Definitions

  • the invention relates to a crack testing device with at least one test unit for checking parts for cracks using a suitable crack testing method and a method for testing parts for cracks using the suitable crack testing method, a first part of the parts to be tested being fed to a first test position and using the in the first test position arranged test unit is checked for cracks.
  • Such crack testing devices or crack testing systems are usually used in manufacturing companies to check the finished products.
  • On the one hand there are crack test systems which destroy the body to be tested during the test, and on the other hand there are non-destructive crack test systems to which the present invention relates.
  • non-destructive crack testing systems of interest a distinction is made between different crack testing methods, for example penetration methods, optical methods or eddy current methods.
  • the eddy current method is a suitable method for locating cracks in the bodies conducting electrical current.
  • Methods using X-ray radiation are suitable as optical crack detection methods.
  • a generic crack testing system is used to find cracks in parts with an outer contour that is rotationally symmetrical in the measuring range.
  • Crack testing systems of this type are based on a substructure that carries the complete testing device including the test specimen supply and removal. Using a rotary table, the test objects are placed in one
  • Transfer position transported.
  • the test specimens are transferred into the test device by transfer devices, where they rotate for the Exam to be transferred.
  • a sensor travels the outer contour of the test specimen, which is coupled to a so-called setting master, who detects the contour of a corresponding sample test specimen and transmits this contour query to the sensor with a corresponding offset for the test (copying unit). After completing the test, the sensor moves into one
  • the crack test device has at least one test unit for checking parts for cracks using a suitable crack test method, the test unit using a displacement unit between at least two
  • Test positions can be moved. Each of the test positions can be supplied with a part of the parts to be tested.
  • a first part of the parts to be tested is fed to a first test position of the test positions and is checked for cracks using the at least one test unit arranged in the first test position. Furthermore, a second Part of the parts to be tested is fed to a second test position of the test positions and the test unit moves to the second test position after testing the first part. Then the second part is checked for cracks using the test unit.
  • the invention includes the technical teaching that the test unit by means of a
  • Travel unit can be moved in at least two test positions. This solution offers the advantage that more parts can be tested per unit of time, with the test device having significantly shorter downtimes, which leads to higher efficiency.
  • the setting master can be saved, which means that the parts to be tested can be changed more quickly by other parts to be tested with different shapes and geometries.
  • CNC programmable controller
  • a supply and removal unit which preferably comprises at least two linearly movable test slide units arranged vertically one above the other, which moves the parts to be tested between different positions. This means that several parts to be tested can be efficiently analyzed in a shorter time.
  • the linearly movable test carriage unit preferably moves between the three positions of the feed, test and removal positions, since optimal utilization of all essential crack test device components is thereby achieved while minimizing the downtimes.
  • the parts to be tested are rotatably mounted in the test carriage unit in the test position, with which the test carriage unit also assumes an abutment function in addition to a transport function.
  • a drive unit can be provided for rotating the parts to be tested, it being advantageous if the drive unit is designed as an electromotive driven friction wheel in the test position on the part to be tested. In this way, an inexpensive drive for the part to be tested can be realized.
  • a control unit with a programmable contour tracking control is preferably provided, with which the movable test unit can be controlled. This enables safe and easy-to-implement control without many components, such as in a copying unit. Contour tracking control can be simple
  • Operation can be programmed by scanning, e.g. the test unit itself or a learning device (manually) is guided along the test route to be traveled by the test unit during the test.
  • the test route to be traveled can also be determined optically by means of image processing.
  • test unit comprises at least one measurement sensor and that the test unit comprising the measurement sensor is mounted on a travel unit. This enables optimal use of the relatively expensive test unit while minimizing downtimes.
  • the travel unit can preferably be a biaxial linear travel unit, since all parts to be tested can be reached for a test of the test positions which are located essentially vertically one above the other.
  • Another advantageous development of the invention also provides that the parts to be tested are transported from the feed and removal unit via a test carriage unit. This enables safe transport of the parts to be tested between the most important positions for the test.
  • Removal unit has at least one longitudinal transfer system per test position, which is coupled to the respective test carriage unit. This allows the transfer of the Decouple the testing parts from a cycle time, so that downtimes can be largely avoided.
  • each longitudinal transfer system transports different parts to be tested. This means that different parts can be fed in parallel during the test.
  • the test unit of the test device additionally has at least one distance measuring unit that measures the distance between the test unit and the part to be tested during the test of a part of the parts to be tested.
  • a corresponding control loop can thus ensure that the test unit is always at the optimum distance from the part to be tested for the measurement.
  • the permanent distance measurement also makes it possible to test parts with an outer contour that is not rotationally symmetrical in the measuring range, the test unit automatically setting the desired distance to the parts to be tested.
  • the distance measurement can be used to implement a self-learning system.
  • the crack testing device has a load-bearing substructure, so that the crack testing device can be adjusted and adjusted via this.
  • a positive development of the invention is that the drive unit rotates the parts to be tested such that they preferably have a speed of at least 1000 revolutions, since this ensures optimal testing of the parts to be tested.
  • a further positive development of the invention is that the parts, in particular ball pins, are provided with an outer contour that is rotationally symmetrical in the measuring range, so that a contour tracking control can be implemented particularly easily on the basis of the geometric conditions.
  • the test position between the feed and take-away positions is arranged with them lying on a straight line.
  • the crack test method is an eddy current method or an optical crack detection method, which e.g. can be realized by means of digital image processing.
  • the test cycle according to the invention can e.g. have the following steps: (a) testing a first part of the parts fed to the first test position for cracks by means of the test unit arranged in the first test position,
  • process step (g) After process step (g), it is possible to return to process step (a) in the test cycle, where the next but one part is then tested as the first part.
