A positioning fixture for component inspection

Abstract

This utility model discloses a positioning fixture for component inspection, relating to the field of component inspection and positioning technology. It includes symmetrically arranged tracks on the surface of an operating table, with several corresponding movable seats slidably connected to the outer sides of the two tracks. Several support mechanisms and two opposing positioning mechanisms are mounted on the tracks via the movable seats. An abutment plate is connected to an interlaced sliding rod within the mounting frame of the positioning mechanism, allowing the abutment plate to move along the sliding rod while the sliding rod moves along a groove on the surface of the mounting frame. This allows for free adjustment of the three-dimensional position of the abutment plate within the mounting frame, precisely adapting to the two ends of irregularly shaped pipe fittings. Simultaneously, telescopic rods extending obliquely in opposite directions within the support mechanism and pipe clamps form a triangular support structure. By clamping the portion of the pipe fitting located between the two mounting frames, any position of the pipe fitting can be supported. The user can freely adjust the position of the pipe clamp by changing the extension length of the corresponding telescopic rod to adapt to different bending directions of the pipe fitting.

Description

Technical Field

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

[0002] After production, parts are sampled and inspected. Regular parts can be clamped and positioned using three-jaw or four-jaw clamps or specific models of clamps corresponding to the parts, so that users can perform inspections.

[0003] However, the components include not only conventional parts, but also some pipes of various shapes. Some pipes have multiple bending areas at different angles due to special use scenarios or specific use requirements. These bending areas make the pipes unsuitable for conventional fixtures. On the other hand, using specific fixtures for testing may result in a large amount of money being spent on research and development, but the frequency of use is limited, resulting in a waste of resources. Existing pipe clamps can only fix the two ends of irregularly shaped pipes, leaving the middle part of the pipe suspended. The suspended pipe part may deform due to its own weight or external forces during testing. Deformation of the pipe will directly affect the accuracy of subsequent testing, or even render the pipe unusable. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a positioning fixture for component inspection, which solves the problem that the clamps used for clamping and fixing irregularly shaped pipes cannot be well adapted to the shape of the pipes.

[0005] The technical solution of this utility model is as follows: it includes two aluminum alloy profile tracks symmetrically arranged on the surface of the operating table, and several corresponding movable seats are slidably connected to the two tracks. Several support mechanisms and two positioning mechanisms arranged opposite each other are installed on the tracks through the movable seats. The positioning mechanism includes a mounting frame connected to a movable seat. The mounting frame has grooves around its perimeter. The mounting frame is provided with staggered sliding rods through the grooves. A stop plate is provided at the staggered position of the sliding rods. The support mechanism includes a telescopic rod connected to the movable seat, and a pipe clamp is rotatably connected to the top of the telescopic rod.

[0006] Furthermore, the movable seats are arranged in groups of two, with positioning mechanisms installed on the top of the two groups of movable seats located on both sides of the track, and a support mechanism installed on the top of the movable seat located between the two positioning mechanisms.

[0007] Furthermore, the mounting frame is integrated into a U-shaped frame structure, and the sliding groove is a through groove connecting the inner and outer sides of the mounting frame. The inner wall of the sliding groove is provided with a limiting protrusion. The sliding groove is slidably engaged with a slider through the limiting protrusion. The sliders in two opposite sliding grooves are connected by a connecting rod, and the connecting rod and the slider constitute a sliding rod.

[0008] Furthermore, the two mounting frames have through grooves on opposite sides of their surfaces that connect to the sliding grooves. Bolts that pass through the through grooves and connect to the sliders are inserted into the outside of the mounting frames. When the bolts are tightened, they abut against the surface of the mounting frames to limit the travel position of the sliders.

[0009] Furthermore, the abutment includes a base plate with an inserted slide rod and an annular stepped protrusion on the surface of the base plate, wherein the diameter of the stepped protrusion is adapted to the inner diameter of pipe fittings of different specifications.

[0010] Furthermore, the telescopic rod is a first-order sleeve, and the section of the telescopic rod connected to the movable seat is the fixed section of the sleeve. A movable section is inserted inside the fixed section, and a fastening bolt that passes through the fixed section and abuts against the movable section is provided on one side of the opening of the fixed section.

[0011] Furthermore, the telescopic rods on the top of the movable seats in the same group are inclined in opposite directions, and the inclined telescopic rods are connected to the same pipe clamp.

[0012] Furthermore, the pipe clamp includes a receiving plate with a downward arc-shaped recess on its surface. A hinge seat is provided at the bottom of the receiving plate for connecting the telescopic rod. An arc-shaped cover plate is hinged to one side of the top of the receiving plate, which covers the receiving plate. The arc-shaped cover plate and the recess on the surface of the receiving plate form a pipe clamp. The end of the arc-shaped cover plate is provided with a buckle for connecting to the receiving plate.

[0013] The beneficial effects of this utility model are as follows: 1. This utility model sets up staggered sliding rods to connect the abutment plate in the mounting frame, so that the abutment plate can move along the sliding rods and the sliding rods can move along the sliding grooves on the surface of the mounting frame. The three-dimensional position of the abutment plate can be freely adjusted in the mounting frame to accurately fit the two ends of the irregular pipe fitting.

[0014] 2. This utility model forms a triangular support structure by using telescopic rods that extend in opposite directions and pipe clamps. By clamping the pipe fitting between the two mounting frames, the pipe fitting can be supported at any position. Users can freely adjust the position of the pipe clamp by changing the extension length of the corresponding telescopic rod to adapt to different bending directions of the pipe fitting.

[0015] 3. Both the positioning mechanism and the support mechanism are installed via rails. Users can set up a number of support mechanisms between the two positioning mechanisms according to actual needs, thereby adapting to pipes of different lengths and with different degrees of curvature and improving the adaptability of the pipes.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figure 1-4 As shown, a positioning fixture for component inspection includes two aluminum alloy profile rails 1 symmetrically arranged on the surface of the operating table. Several corresponding movable seats 2 are slidably connected to the two rails 1. Several support mechanisms 3 and two positioning mechanisms 4 arranged opposite each other are installed on the rails 1 through the movable seats 2. The movable seats 2 are in groups of two. The positioning mechanism 4 is set on the top of the two groups of movable seats 2 located on both sides of the rails 1. The support mechanism 3 is set on the top of the movable seat 2 located between the two positioning mechanisms 4. The positioning mechanism 4 includes a mounting frame 401 connected to the movable seat 2. The mounting frame 401 has a sliding groove 402 around its perimeter. The surfaces of the two mounting frames 401 facing each other have through grooves that communicate with the sliding grooves 402. Bolts that pass through the mounting frame 401 and connect to the slider are provided in the through grooves. When the bolts are tightened, they abut against the surface of the mounting frame 401 and tighten the slider's stroke position limit. The mounting frame 401 is provided with staggered sliding rods 403 within the mounting frame 401 via a sliding groove 402. The mounting frame 401 is integrated into a U-shaped frame structure. The sliding groove 402 is a through groove connecting the inner and outer sides of the mounting frame 401. A limiting protrusion is provided on the inner wall of the sliding groove 402. A slider is slidably engaged in the sliding groove 402 through the limiting protrusion. The sliders in two opposite sliding grooves 402 are connected by a connecting rod. The connecting rod and the slider constitute the sliding rod 403. A stop plate 404 is provided at the staggered position of the sliding rods 403. The stop plate 404 includes a base plate through which the sliding rods 403 pass and an annular stepped protrusion provided on the surface of the base plate. The diameter of the stepped protrusion is adapted to the inner diameter of pipe fittings of different specifications. The support mechanism 3 includes a telescopic rod 301 connected to the movable seat 2. The telescopic rod 301 is a first-stage sleeve. One section of the telescopic rod 301 connected to the movable seat 2 is a fixed section of the sleeve. A movable section is inserted into the fixed section. A fastening bolt that passes through the fixed section and abuts against the movable section is provided on one side of the opening of the fixed section. A pipe clamp 302 is rotatably connected to the top of the telescopic rod 301. The telescopic rods 301 on the top of the movable seat 2 in the same group are inclined towards each other. The inclined telescopic rods 301 are connected to the same pipe clamp 302. The pipe clamp 302 includes a receiving plate. The surface of the receiving plate is provided with a downward arc-shaped recess. A hinge seat is provided at the bottom of the receiving plate to connect the telescopic rod 301. An arc-shaped cover plate covering the receiving plate is hinged to one side of the top of the receiving plate. The arc-shaped cover plate and the recess on the surface of the receiving plate form a pipe clamp. A buckle connected to the receiving plate is provided at the end of the arc-shaped cover plate.

[0020] Working principle of this utility model: Using two parallel aluminum alloy tracks 1 on the operating table surface as a reference, the movable seat 2 slides along the tracks 1 to adjust the distance between the support mechanism 3 and the positioning mechanism 4. The support mechanism 3 adopts a triangular stable structure formed by the opposing inclined telescopic rods 301 and the pipe clamp 302. The telescopic rods 301 extend and retract to drive the pipe clamp 302 to rise and fall and deflect at an angle. The pipe clamp formed by its arc-shaped concave and the cover plate adaptively clamps the pipe fitting and disperses stress. The positioning mechanism 4 drives the stepped abutment plate 404 to perform three-dimensional spatial adjustment through the staggered sliding rods 403 in the sliding grooves 402 around the mounting frame 401. The stepped surface of the abutment plate 404 abuts the bend or end face of the pipe fitting to achieve adaptive positioning. Finally, through the synergistic effect of the sliding adjustment of the movable seat 2, the triangular rigid support of the support mechanism 3, and the multi-dimensional adaptive positioning of the positioning mechanism 4, the irregularly shaped bent pipe fittings of different specifications can obtain accurate spatial positioning, multi-point stable support, and rapid shape change capability during the inspection process, thereby ensuring inspection accuracy and efficiency.
