Description

Grip clamping positioning structure

This creation is about the clamping and positioning structure of the fixture, especially for the case where various workpieces are clamped, the fixture can be assembled quickly, and the clamping structure of the workpiece is firmly clamped.

The workpiece clamping mechanism (commonly known as the vise), which is commonly used in processing machines, is mainly provided with a fixed cymbal at one end, and a movable cymbal driven by a screw is slid on the top surface, thereby fixing the workpiece.颚 and movable 颚 are clamped and fixed to facilitate the processing operation; however, such a clamping mechanism can only clamp one workpiece at a time for single workpiece processing, and the processing personnel must frequently operate during a large number of processing operations. Replacing the workpiece on the clamping mechanism causes troubles and inconveniences in the work.

Another common workpiece clamping mechanism is disclosed in the sixth and seventh figures of the new patent application No. M380192, "Vise clamp structure", which has an elongated body with a longitudinally extending T-shaped groove in the center. The top surface of the body is distributed with a plurality of fixed teeth, and the top surface of the body is provided with a plurality of reference blocks and an array clamp. Each of the bottom surfaces of the reference block forms a plurality of fixed teeth to be engaged with the fixed teeth of the body, and the bottom of the reference block is screwed. A T-shaped locking block that is slidably disposed in the T-shaped groove of the body.

Each clamp is composed of left and right clamps, and the opposite sides of the left and right clamps form an inclined surface, and a V-shaped clamping block is interposed between the left and right clamps, and the bottom of the V-shaped clamping block is screwed with a T a locking block, the locking block is slidably disposed in the T-shaped groove of the body, and the V shape of each clamp When the clamping block locks the bolt, the V-shaped clamping block is forced to be pressed down, and the left and right clamps are moved outward to clamp the workpiece, so that the workpieces are respectively fixed between the clamp and the reference block.

Since the spacing between the left and right clamps of the vise structure is very small, when the operator wants to clamp the workpiece for production and processing, only the loosening and locking of the bolts is required to achieve the function of releasing and clamping the workpiece. It is not necessary to use a vise as a conventional one, and it takes time and effort to rotate the screw, and the vise can hold many workpieces at the same time for production and processing, effectively solving the lack of application of the aforementioned workpiece clamping mechanism.

However, in the above structure, the following problems still exist in use:

1. Since the center of the body is provided with a T-shaped groove extending longitudinally (opening upwards), the metal slag generated by the tool machine machining the workpiece easily falls into the T-shaped groove, so the body must be periodically removed. Metal slag in the T-shaped groove, otherwise the metal slag will hinder the movement of the T-shaped locking block in the T-shaped groove, forming an application defect.

2. Whenever different reference blocks and clamping jaws need to be replaced according to different workpiece sizes, in order to replace the T-shaped locking block, the chip must be removed before the locking block can be loosened, and then the lock can be re-removed and then re-inserted. After the block is tightened, the locking block is re-fixed, so that the reference blocks and the clamps are not easy to be aligned with the T-shaped locking block, so that the adjustment work of each T-shaped locking block and each reference block and the jig is extremely time-consuming and troublesome, and the application is formed. Missing.
