Description

Technical Field

[0001] This utility model belongs to the field of measurement technology, and in particular relates to a gauge for internally fixed parts. Background Technology

[0002] With the development of technology, the precision requirements of parts are getting higher and higher. Therefore, after the industrial products are manufactured, comprehensive dimensional measurements are often required to check whether they meet the design requirements. However, product designs are generally quite complex, with many irregular surfaces, and the outer surface of the product also has surface finish requirements, which makes it impossible to clamp from the outside during measurement. If clamping is not possible, measuring various dimensions becomes very troublesome. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0004] A fixture for internal fixation parts includes a frame body, a contour block mounted on the frame body, and several internal fixation components;

[0005] The internal fixation assembly includes a driving part and several fixing parts, and the driving part and the fixing parts are connected by a connecting part; when the driving part is driven, the fixing parts can be fixed / loosened through the connecting part.

[0006] Furthermore, the fixing part includes a fixing block and a limiting block rotatably connected to the fixing block. The fixing block is also provided with an elastic element and a receiving hole. One end of the elastic element abuts into the hole, and the other end abuts against the limiting block.

[0007] Furthermore, the drive unit is a brake handle.

[0008] Furthermore, the connecting part is a brake cable, and the brake handle is provided with several connection ports. One end of the brake cable is connected to the connection port, and the other end is connected to the fixing part.

[0009] Furthermore, the elastic element is a spring.

[0010] Furthermore, one end of the gate cable connection fixing part passes through the spring and is fixedly connected to the limiting block. When the gate cable is pulled, the limiting block rotates towards the gate cable entry side to limit it. After being released, the spring resets and opens the limiting block in the opposite direction.

[0011] Furthermore, the top of the limiting block is provided with a buckle, which is used to engage the inner edge of the product.

[0012] Furthermore, the frame body is also equipped with a transport bracket for easy handling.

[0013] The beneficial effects of this utility model are:

[0014] When using this invention, the product is placed on the contour block, and the limit block is pulled by the brake cable. The limit block has a buckle on the top. When the brake cable is pulled, the buckle can lock the inner edge of the product to the side, clamping and fixing the product from the inside. For products with requirements on the outer surface, it can effectively protect the outer surface of the product. For products whose outer surface cannot be clamped, it is also a good solution.

[0024] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention. Specific Implementation Example 1:

[0026] like Figures 1 to 4As shown, a fixture for internally fixed parts includes a frame body 1, a contour block 2 and several internally fixed components 3 mounted on the frame body 1; for ease of handling, the frame body 1 is also provided with a handling bracket 11 for easy handling.

[0027] The internal fixing component 3 includes a driving part 31 and several fixing parts 32. The driving part 31 and the fixing parts 32 are connected by a connecting part 33. When the driving part 31 is driven, the fixing parts 32 can be fixed / released through the connecting part 33. Specifically, the driving part 31 is a brake handle. Specifically, the connecting part 33 is a brake cable. The brake handle has several connection ports. One end of the brake cable is connected to the connection port, and the other end is connected to the fixing part 32. Specifically, one end of the brake cable connected to the fixing part 32 passes through a spring and is fixedly connected to the limiting block 322. When the brake cable is pulled, the limiting block 322 rotates towards the side where the brake cable enters to limit it. After release, the spring returns to its original position, opening the limiting block 322 in the opposite direction.

[0028] Specifically, the fixing part 32 includes a fixing block 321 and a limiting block 322 rotatably connected to the fixing block 321. The fixing block 321 also has an elastic element 323 with a receiving hole. One end of the elastic element 323 abuts into the hole, and the other end abuts against the limiting block 322. Specifically, the elastic element is a spring. The limiting block 322 has a buckle 322-1 at its top, which is used to engage the inner edge of the product.
