Description

A garbage compression device and its self-adjusting pin shaft

technical field

The invention relates to garbage compression equipment and a self-adjusting pin shaft thereof, belonging to the technical field of environmental protection equipment.

Background technique

With the development of waste compression equipment, especially the widespread use of three-compression oil cylinder staged relay compression technology, the problem of pin connection between hydraulic cylinders and structural parts is faced in the equipment manufacturing process. As a commonly used fastener, the pin shaft is fixed by inserting the pin shaft into the pin hole. Since the pin shaft connection is a static rigid connection, once a pair of shaft holes are fitted in place, the central shaft system of the other pin shafts is the same as the axis of the hinge hole. It is difficult to adjust the shaft degree, which makes it difficult to install the subsequent pin shaft. If the pin shaft is forced into the hinged hole, it is easy to cause scratches or damage on the processed surface of the pin shaft or the hinged hole.

At present, for the pin shaft connection method, the usual method is: one structure, a large chamfer is processed at the joint between the pin shaft and the hinge hole, to increase the guiding of the workpiece when the pin shaft is installed axially, and the other structure, The cross section of the pin shaft seat adopts the form of an oblong hole. There are following defects in the above-mentioned pin mechanism mode:

1. The pin shaft is processed with a large chamfer. After installation, the workpiece must protrude from the pin shaft seat, which requires more space at the pin shaft connection, resulting in an increase in the structure of related parts, which has a greater obstacle to the improvement of the performance of the garbage compression equipment. .

2. The fit between the hinged hole and the pin shaft is generally a transition fit. If the centerline of the pin shaft and the axis of the hinged hole are not on the same axis, the workpiece will be subjected to a certain bending stress if the pin shaft is forcibly installed.

3. The contact surface between the hinged hole and the pin shaft is in linear contact, and the stress on the pin shaft is poor, which will easily cause the pin shaft to fail and affect the service life of the pin shaft.

Contents of the invention

The technical problem to be solved by the present invention is to overcome the defects of the prior art, provide a garbage compression equipment and its self-adjusting pin shaft, and realize the horizontal adjustment of the pin shaft through a guide block sliding horizontally in the pin shaft seat, thereby The horizontal adjustment of the position of the pin shaft relative to the hinge hole is realized, which effectively solves the problem of horizontal adjustment of the pin shaft and hinge hole installation, effectively protects the processed surface of the pin shaft, and improves the reliability of the pin shaft installation.

In order to solve the above technical problems, the present invention provides a self-adjusting pin shaft, including a pin shaft seat, which is characterized in that a horizontal sliding device is provided in the pin shaft seat, and a guide block is provided in the horizontal sliding device. There is a movement gap between the guide block and the horizontal sliding device; a pin hole is provided in the guide block, and the pin shaft is installed in the pin shaft hole; a pin for fixing the guide block is provided on the pin seat. Shaft baffle.

The aforementioned self-adjusting pin is characterized in that the horizontal sliding device is a sliding hole.

The aforementioned self-adjusting pin is characterized in that the section of the sliding hole is trapezoidal.

The aforementioned self-adjusting pin is characterized in that the section of the guide block is square.

The aforementioned self-adjusting pin is characterized in that the pin baffle is fixed on the guide block by a fastener.

The aforementioned self-adjusting pin is characterized in that the fastener is a bolt or a screw.

The present invention also provides a garbage compression device, which is characterized in that the aforementioned self-adjusting pin is arranged on the garbage compression device.

The beneficial effects achieved by the present invention: through the pin connection mode, the shortcomings of the prior art of garbage compression equipment are overcome, and the guide block can be horizontally slid in the pin seat, and the pin shaft can be conveniently installed on the guide block ;The use of guide blocks can ensure that the pin shaft adjustment, pin shaft guidance, and installation are in a better protection state, effectively preventing scratches or damage on the pin shaft's processed surface.

detailed description

The present invention will be further described below in conjunction with the accompanying drawings. The following examples are only used to illustrate the technical solution of the present invention more clearly, but not to limit the protection scope of the present invention.

As shown in Figures 2 to 5, a self-adjusting pin includes a pin seat 3, and a horizontal sliding device is provided in the pin seat 3, and the horizontal sliding device is a sliding hole 6, and the sliding hole 6 The cross section is trapezoidal. A guide block 2 is arranged inside the horizontal sliding device, and the cross section of the guide block 2 is square. The guide block 2 is provided with a pin hole 7 , and the pin 1 is installed in the pin hole 7 .

There is a movement gap between the guide block 2 and the sliding hole 6, thereby protecting the pin shaft 1, avoiding the bending stress of the pin shaft 2, improving the overall reliability of the pin shaft connection mode, and effectively preventing the pin shaft from being damaged. Scratches or damage to the machined surface.
