Description

Technical Field

[0001] This utility model belongs to the field of automotive parts inspection tools, specifically relating to a linear slide inspection mechanism on automotive inspection tools. Background Technology

[0002] In automotive parts inspection fixtures, due to the limitations of the parts' structure, some inspection positions require sliding mechanisms with a larger stroke to meet space constraints. However, the standard sliding mechanisms used in practice have a fixed stroke and limited sliding range, which cannot meet the design requirements of the fixture. In addition, some fixtures require the movement of the entire unit, i.e., several inspection blocks or inspection blocks with supports moving together, which is quite heavy. Standard fixture sliding mechanisms are even less able to meet these requirements. They cannot connect multiple inspection blocks, cannot withstand excessive weight, cannot quickly switch between different inspection needs, cannot select the length of the linear guide rail according to the required stroke, and cannot select a single or double slider on a single rail according to the size of the slide table connecting plate. The structure is not stable enough, the positioning is not accurate enough, and the inspection accuracy of the fixture cannot be effectively guaranteed, thus failing to meet the usage requirements of the fixture.

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.

[0017] Please see Figure 1-4 This utility model provides a technical solution: a linear slide mechanism for automotive inspection tools, including a base plate 1, a guide rail assembly 2, a connecting plate 3, a limiting block 4, a positioning seat 5, a flip-up positioning block 6, a rotating shaft 7, and an anti-loosening nut 8. The guide rail assembly 2 is provided on the base plate 1, and the connecting plate 3 is provided above the guide rail assembly 2. The connecting plate 3 is used to install multiple different inspection blocks, which can meet the needs of quick switching between different inspections. Installing multiple inspection blocks can withstand a large weight. At the same time, the guide rail assembly 2 has limiting blocks at both ends. Block 4, limit block 4 In order to prevent the connecting plate 3 from falling off the guide rail assembly 2, a positioning seat 5 is provided on one side of the guide rail assembly 2. The positioning seat 5 is used to fix the connecting plate 3 in the position required by the user. The side of the connecting plate 3 close to the positioning seat 5 is provided with a flip-up positioning block 6 through the rotating shaft 7. The flip-up positioning block 6 can be positioned and fixed in the slot of the positioning seat (5) according to the detection needs. An anti-loosening nut 8 is provided at one end of the rotating shaft 7. The anti-loosening nut 8 is used to fix the rotating shaft 7 on the connecting plate 3 to prevent the rotating shaft 7 from falling off the connecting plate 3.

[0018] The guide rail assembly 2 in this example includes a guide rail 201 and a slide table 202. There are two guide rails 201, which provide a fixed movement path for the slide table 202, ensuring that it moves in a predetermined direction and avoiding deviation or shaking. The structure is stable and the positioning is accurate, which can effectively guarantee the detection accuracy of the inspection tool. The length of the linear guide rail can also be selected according to the needs of the usage stroke. Each guide rail 201 is equipped with a slide table 202, which is a moving part that can be loaded and can bear weight. At the same time, the slide table 202 has a threaded hole, which is for easy fixing of the connecting plate 3 to the slide table 202 with screws.

[0019] In this example, the positioning seat 5 includes a non-detection positioning seat 501 and a detection positioning seat 502. The non-detection positioning seat 501 and the detection positioning seat 502 are used to fix the connecting plate 3 in a suitable position according to the needs of non-detection or detection. Both the non-detection positioning seat 501 and the detection positioning seat 502 are provided with slots. The slots are provided to facilitate the positioning and fixing of the flip-up positioning block 6.

[0020] In this example, the connecting plate 3 is fixed to the slide table 202 with screws. The screw fixing facilitates the disassembly and installation of the connecting plate 3. The connecting plate 3 is provided with multiple threaded holes.

[0021] In this example, the flip-up positioning block 6 can rotate around the rotation axis 7, and the flip-up positioning block 6 can rotate to facilitate the movement of the connecting plate 3.

[0022] In this example, the guide rail assembly 2, the limit block 4, and the positioning seat 5 are all positioned on the base plate 1 by bolts. The bolts facilitate the installation and disassembly of each component.

[0023] Working principle: such as Figure 4The image shows a three-way catalytic converter assembly for a car exhaust pipe (e.g., Figure 4 The fixture at point c is designed with two sets of guide rail assemblies (e.g., ...). Figure 4 At points a and b), multiple detection blocks are mounted on the connecting plate 3. These blocks are relatively heavy and are used to inspect parts in two different states. During loading, first open all moving mechanisms on the fixture, open the pneumatic clamping mechanism, and move the two sets of guide rail assemblies 2 outwards to the non-detection positioning seat 501 slot. After loading the parts and pressing the cylinder clamping button, the parts can be inspected. When it is necessary to use... Figure 4 When inspecting guide rail assembly 2 at point a, it is only necessary to... Figure 4 The reversible positioning block 6 of the guide rail assembly 2 at point a flips out from the slot of the non-detection positioning seat 501, and... Figure 4 The guide rail assembly 2 at point a is pushed to the detection position, and the flip-up positioning block 6 is flipped into the slot of the detection positioning seat 502 for positioning. At this time, Figure 4 The detection mechanism on the guide rail assembly 2 at point a detects the dimensions of the part. Figure 4 When inspecting guide rail assembly 2 at point b, simply follow the same method first... Figure 4 The guide rail assembly 2 at point a slides out and then is pushed in. Figure 4 After the guide rail assembly 2 at point b is positioned, the part can be inspected. After the inspection is completed, both guide rail assemblies 2 are pushed out to the non-inspection position. After the cylinder is opened, the part can be removed. This completes the entire work.
