After the stamping and forming of auto parts, various indicators need to be tested, and inspection tools are required for testing. The inspection tool is a kind of inspection tool specially manufactured according to specific requirements. When the inspection tool is inspected, it is necessary to locate the parts to be inspected, and then to inspect each inspection position of the parts. The existing positioning device has low precision and cannot be flexibly adjusted and locked. The depth, the compression locking part directly contacts the surface of the workpiece, the damage caused to the workpiece will reduce the product quality and affect the detection accuracy.

Utility model content

The purpose of this utility model is to provide a pair of positioning pins for inspection tools to solve the problems in the prior art above, so that the locking depth of the auxiliary positioning pins can be flexibly adjusted, and the positioning and locking effect is better.

In order to achieve the above object, the utility model provides the following scheme:

The utility model provides a pair of positioning pins for inspection tools, which is characterized in that it includes a locking rod, a handle is fixed on the locking rod, an insertion rod is fixed at one end of the locking rod, and the insertion rod is movable A pin positioning block is connected, and the locking rod is movably connected with a locking nut and a special-shaped pressing block,

One end of the locking rod is semi-cylindrical, and the middle part of the special-shaped pressing block is provided with a semi-circular through hole. The block slides on the locking lever.

Preferably, the shape of the special-shaped compacting block is one of oblong, elliptical, pentagonal or hexagonal.

Preferably, the handle, locking nut, special-shaped pressing block, and pin positioning block are arranged in sequence, and the handle, locking rod, and insertion rod are arranged coaxially.

Preferably, the insertion rod is a threaded rod that is movably connected with the pin positioning block through threads.

Preferably, the lock nut is movably connected to the lock rod through threads.

Preferably, part identification is engraved on the handle.

The utility model discloses the following technical effects:

The auxiliary positioning pin of the inspection tool of the utility model adopts a split structure, which can adjust the pressing depth and locking depth. Effectively avoid the locking surface being not parallel to the product, resulting in poor locking and affecting the detection structure, avoiding the damage caused by the direct screwing and locking of the lock nut to the workpiece, and indirectly improving the quality of the workpiece and the accuracy of detection .

The utility model has the advantages of simple structure and low cost, and can ensure the precision and locking depth of the positioning fixture.

detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

In order to make the above purpose, features and advantages of the utility model more obvious and understandable, the utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

The utility model provides a pair of positioning pins for inspection tools, which include a locking rod 1, on which a handle 2 is fixed, on which a part mark is engraved, and one end of the locking rod 1 is fixed with an insertion rod 3, which is inserted into the The pin positioning block 4 is movably connected on the rod 3, and the locking rod 1 is movably connected with a lock nut 5 and a special-shaped compression block 6, so that the special-shaped compression block 6 slides on the locking rod 1, and the handle 2, the lock nut 5 , special-shaped pressing block 6, and pin positioning block 4 are set in sequence, handle 2, locking rod 1, and inserting rod 3 are coaxially arranged, and inserting rod 3 is a threaded rod that is movably connected with the pin positioning block 4 through threads to lock The nut 5 is movably connected with the locking rod 1 through threads.

To further optimize the scheme, in order to adapt to the shape of the workpiece, the shape of the special-shaped pressing block 6 is one of oblong, elliptical, pentagonal or hexagonal, and the application range is wider.

To further optimize the scheme, when the lock nut 5 is screwed, it will drive the special-shaped compression block 6 to compress downwards. In order to prevent the special-shaped compression block 6 from rotating and causing damage to the workpiece, one end of the locking rod 1 is semi-cylindrical. The middle part of the tight block 6 is provided with a semicircular through hole 7, and the semicircular through hole 7 is compatible with the semi-cylindrical shape at one end of the locking rod 1. The workpiece is pressed downward along the locking rod 1, and the pressing effect is good, the damage to the workpiece is small, and the detection accuracy is improved.

When in use, the insertion rod 3 is inserted into the auxiliary positioning pin hole on the inspection tool by turning the handle 2, the pin positioning block 4 positions the workpiece, and the locking nut 5 drives the special-shaped pressing block 6 to lock the workpiece downward. Tighten, inspect after fixing the parts, unscrew the auxiliary positioning pin after the inspection is completed.

The above-mentioned embodiment is only to describe the preferred mode of the present utility model, not to limit the scope of the present utility model. The various deformations and improvements mentioned above should all fall within the scope of protection determined by the claims of the present utility model.
