Description

Technical Field

[0001] This utility model relates to the field of fixture positioning technology, and in particular to a sliding positioning structure for a fixture. Background Technology

[0002] In the industrial manufacturing sector, especially in the production of parts with complex and irregular structures, inspection fixtures are key equipment used to check whether the dimensions, contours, and positional tolerances of products meet design requirements. Their core function is to quickly and accurately position and fix the measured item at a preset inspection reference position for subsequent measurement and judgment.

[0003] For irregularly shaped inspection items with non-planar bottom structures, protrusions, depressions, or curved surfaces, traditional fixture positioning methods typically employ fixed support blocks or clamps to hold the irregular surfaces. However, fixtures using this method are often only suitable for a specific product and have poor versatility. When the product model changes or when it is necessary to inspect parts with similar but different irregular structures, it is difficult to flexibly adjust the support points, which may lead to unstable positioning of irregular parts, uneven distribution of clamping force, or even scratches or deformation of the product surface during clamping, affecting the inspection accuracy. In some cases, it may even be necessary to redesign and manufacture the entire fixture, which is costly and time-consuming. Utility Model Content

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] This utility model provides, for example Figures 1-4 The diagram shows a sliding positioning structure for an inspection fixture.

[0019] Example 1 includes an operating table 100, a support frame 200, a positioning component 300, a fixing frame 400, a support sleeve 600, and a U-shaped frame 700. The operating table 100 serves as the inspection surface for the test item. Multiple support frames 200 are installed at both ends of the operating table 100. Multiple positioning components 300 are disposed between two opposing support frames 200. The positioning components 300 are used to support the irregular bottom of the test item. The fixing frame 400 is fixed to the middle of the operating table 100 and is used to support the middle of the test item. The support sleeve 600 and the U-shaped frame 700 are respectively installed on one side of the multiple positioning components 300. The support sleeve 600 has a rectangular cylindrical structure, and the U-shaped frame 700 has a U-shaped structure, which facilitates clamping and limiting the bottom of the test item.

[0020] The support frame 200 includes a frame body 201 and a mating groove 202. The frame body 201 is fixed to the upper surface of the operating table 100 by screws. The mating groove 202 is opened on the top side of the frame body 201. The mating groove 202 is used to engage with the end of the test sample. The opening of the mating groove 202 facilitates the limiting of the end of the test sample and improves the stability of the support and positioning of the test sample.

[0021] In addition, the positioning component 300 includes a positioning frame 301, rubber pads 302, and an electric telescopic rod 303. The positioning frame 301 slides between the frame 201 and the fixed frame 400. The positioning frame 301 has an L-shaped structure. Multiple rubber pads 302 are fixed to the top of the positioning frame 301 and the top of the fixed frame 400, respectively. The rubber pads 302 are made of rubber to reduce frictional damage to the bottom of the sample. The electric telescopic rod 303 is fixedly inserted into one side of the positioning frame 301. The top telescopic end of one electric telescopic rod 303 is fixedly connected to the bottom of the support sleeve 600, and the top telescopic end of the other electric telescopic rod 303 is fixedly connected to the bottom of the U-shaped frame 700. The electric telescopic rod 303 is electrically connected to an external power source through an external switch. Driven by the electric telescopic rod 303, the support sleeve 600 and the U-shaped frame 700 can engage and limit the irregular parts of the lower surface of the sample, thereby improving the stability of the sample detection.

[0022] Example 2, based on Example 1, further includes a limiting component 500. The limiting component 500 is installed between the positioning component 300 and the operating table 100. The limiting component 500 is also installed between multiple positioning frames 301 and the operating table 100. The limiting component 500 includes a T-slot 501, a positioning block 502, a wear-resistant pad 503, and a screw 504. The T-slot 501 is formed on the upper surface of the operating table 100, and the positioning block 502 is inserted into the bottom of the positioning frame 301. The side cross-section of the positioning block 502 is an inverted T-shaped structure. Multiple positioning blocks 502 slide within the inner cavity of the T-slot 501. The positioning blocks 502 can slide horizontally within the inner cavity of the T-slot 501 without detaching from it. A wear-resistant pad 503 is fixed to the top of the positioning block 502. The wear-resistant pad 503 has a ring-shaped structure and is used for pressing and adhering to the top of the inner wall of the T-slot 501. The screw 504 rotates via a bearing. Inserted into the top of the positioning block 502, the screw 504 is threadedly connected to one side of the positioning frame 301. By manually rotating the top of the screw 504, it can move at the bottom of the positioning frame 301, allowing the positioning block 502 to move up and down. This facilitates the wear-resistant pad 503 to tightly fit the inner wall of the T-slot 501, improving the stability of the positioning frame 301 on the operating table 100. It also allows the positioning frame 301 to move to different parts of the bottom of the test item, enabling the electric telescopic rod 303 to drive the support sleeve 600 and the U-shaped frame 700 to provide irregular support for the bottom of the test item, improving the stability of the bottom position of the test item and facilitating strength testing of the test item by the inspection tool. The limiting component 500 constitutes a set of efficient fine-tuning and locking mechanisms, which can firmly lock the positioning frame 301 in any desired position on the operating table 100, improving the convenience of adjustment and ensuring the rigidity of the entire structure when subjected to testing force.
