Embodiment 1

[0021] see Figure 1 to Figure 4 , the figure shows a screw length detection and positioning fixture provided by Embodiment 1 of the present invention, including a bench vise 1 and a positioning block 2, the bench vise 1 includes a vise body 11 and a movable pliers arm 12, the vise body 11 is provided with a fixed jaw 111, the movable clamp arm 12 is provided with a movable jaw 121 corresponding to the fixed jaw 111, the positioning block 2 is fixedly installed on the movable jaw 121, and the positioning block 2 is provided with a V-shaped groove 21, The opening of the V-shaped groove 21 extends to the top of the positioning block 2 , the screw 3 is placed in the V-shaped groove 21 , and the screw 3 is perpendicular to the positioning block 2 .

[0022] Specifically, see Figure 1 to Figure 4 , The bench vise 1 also includes a rotating base 13 on which the vise body 11 is rotatably mounted.

[0023] Specifically, see Figure 1 to Figure 4 , The two sides of the vise body 11...

Embodiment 2

[0029] see Figure 1 to Figure 4 , the figure shows a screw length detection and positioning jig provided by Embodiment 2 of the present invention. On the basis of the above embodiments, this embodiment further makes the following technical solutions as improvements: the pressure rod 42 is set There is an arc bent portion 421 .

[0030] In order to make the contact area of ​​the pressure rod larger when pressing against the surface of the screw and fit the surface of the screw more closely, the pressure rod is provided with an arc-shaped bending part, which effectively improves the positioning effect of the screw.

Embodiment 3

[0032] see Figure 1 to Figure 4 , the figure shows a screw length detection and positioning jig provided by Embodiment 3 of the present invention. On the basis of the above embodiment, this embodiment further makes the following technical solution as an improvement: the bump 23 is slidingly connected On the positioning block 2 , two symmetrically arranged rods 232 are arranged on the back of the protruding block 23 , the rods 232 are perpendicular to the positioning block 2 , and the rods 232 pass through the positioning block 2 .

[0033] The bump is slidingly connected to the positioning block through two rods, and the movable jaw is also provided with a groove corresponding to the rod body, so that the length of the bump protruding from the positioning block is greater than the thickness of the positioning block, and the bump can extend out of the positioning block by changing length to support screws of different lengths.

Abstract

The invention provides a screw length detecting and positioning jig. The jig comprises a bench vice and a positioning block, the bench vice comprises a vice body and a movable vice arm, a fixed vice opening is formed in the vice body, a movable vice opening corresponding to the fixed vice opening is formed in the movable vice arm, the positioning block is fixedly installed on the movable vice opening, a V-shaped groove is formed in the positioning block, an opening of the V-shaped groove extends to the top end of the positioning block, the screw is placed in the V-shaped groove, and the screwis perpendicular to the positioning block. According to the screw length detecting and positioning jig provided by the invention, screws with different diameters can be positioned, and the screws areensured to be perpendicular to the fixed jaw, so that data is accurate during screw length detection.

Description

technical field [0001] The invention relates to a positioning jig, in particular to a screw length detection and positioning jig. Background technique [0002] Screws are a common fastener widely used in machinery, electrical appliances and buildings. It is generally made of metal or plastic and is cylindrical in shape. The grooves carved on the surface are called threads. [0003] When screw length detection is required, a vise is often used to fix the screw for length detection. When positioning the screw with a vise, the screw cannot be effectively positioned to ensure the horizontal placement of the screw, so the error of the measurement data is relatively large. Contents of the invention [0004] In view of this, the present invention provides a screw length detection and positioning jig, which can fully locate the position of the screw and ensure the accuracy of data during screw length detection. [0005] For this reason, the present invention provides a kind of ...
