Description

Technical Field

[0001] This utility model relates to the technical field of machining, specifically to a parallel guide rail assembly and testing device. Background Technology

[0002] In existing processes, the assembly quality inspection of parallel guide rails is mainly carried out through manual visual inspection. The inspection items mainly include: whether the assembly direction and riveting direction of the guide wheels are correct, whether the installation direction of the two wing sliding plates is correct, and whether there are any missing parts.

[0003] The aforementioned existing technical solutions have the following drawbacks: relying on operators for visual inspection is not only prone to errors due to visual fatigue, but also inevitably affected by subjective judgment. This has become a potential risk point in quality control, directly restricting the improvement of product qualification rate. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a parallel guide rail assembly and inspection device that can replace manual operation, reduce the decline in output and quality caused by subjective judgment, and improve the product assembly qualification rate.

[0005] The above-mentioned objective of this utility model is achieved through the following technical solution:

[0006] A parallel guide rail assembly testing device includes a base plate on which two parallel support blocks are mounted. A limiting block is connected above the two support blocks, and the two ends of the limiting block are respectively connected to the two different support blocks.

[0007] In the vertical direction, the projection of the limiting block is perpendicular to the projection of the supporting block;

[0008] A proximity switch is also installed on the base plate. A power supply is provided on one side of the proximity switch, and an indicator light is connected to the other side of the power supply. The proximity switch, the indicator light, and the power supply are electrically connected.

[0009] In a preferred embodiment, the present invention can be further configured such that: a limiting strip is also connected to the lower side of the limiting block, the limiting strip is parallel to the support block, and the limiting strip is detachably connected to the limiting block.

[0010] In a preferred embodiment, the present invention can be further configured such that: a limiting pin is provided on the lower side of the limiting strip, the bottom of the limiting pin is a threaded rod, and the limiting pin is connected to the test piece by bolts.

[0011] In a preferred embodiment, the present invention can be further configured such that: an L-shaped component is sleeved on the limiting pin, one side of the L-shaped component faces the proximity switch, and when the test piece is a qualified product, the L-shaped component is in contact with the proximity switch.

[0012] In summary, this utility model has at least one of the following beneficial technical effects:

[0013] The mistake-proof structure adopted in this application can accurately and reliably replace traditional manual inspection methods, effectively eliminating subjective misjudgments and batch quality problems caused by human factors. This system significantly improves the consistency and pass rate of the product assembly process, enhancing quality control while also significantly optimizing production efficiency, thereby driving a dual leap in both quality and efficiency.

[0018] The present invention will be further described in detail below with reference to the accompanying drawings.

[0019] like Figure 1-3 As shown, a parallel guide rail assembly testing device includes a base plate 1, on which two parallel support blocks 2 are installed. A limiting block 3 is connected above the two support blocks 2, and the two ends of the limiting block 3 are respectively connected to the two different support blocks 2.

[0020] In the vertical direction, the projection of the limiting block 3 is perpendicular to the projection of the support block 2;

[0021] A proximity switch 4 is also installed on the base plate 1. A power supply 5 is provided on one side of the proximity switch 4. An indicator light 6 is also connected to the side of the power supply 5. The proximity switch 4, the indicator light 6 and the power supply 5 are electrically connected.

[0022] Furthermore, a groove can be formed between the two support blocks 2, which can also be used to limit the position of the test piece 10. In addition, the position of the two support blocks 2 is not limited here, and a pushing device can be used for the support blocks 2, for example, by using a cylinder to push the support blocks 2 to change the distance between the two support blocks 2, thereby improving the applicability of the device.

[0023] Furthermore, a limiting strip 7 is connected to the lower side of the limiting block 3. The limiting strip 7 is parallel to the support block 2 and is detachably connected to the limiting block 3. A limiting pin 8 is also provided on the lower side of the limiting strip 7. The bottom of the limiting pin 8 is a threaded rod, and the limiting pin 8 is connected to the test piece 10 by bolts. The limiting strip 7 and the limiting pin 8 here, like the support block 2 mentioned above, are foolproof structures used to fix the test piece 10. Similarly, the limiting strip 7 and the limiting pin 8 can also be equipped with a pushing device to improve the applicability of the device.

[0024] Furthermore, an L-shaped component 9 is fitted onto the limit pin 8, with one side of the L-shaped component 9 facing the proximity switch 4. When the part to be tested 10 is a qualified product, the L-shaped component 9 is in contact with the proximity switch 4. The end face of the L-shaped component 9 is provided with contacts for forming a circuit with the proximity switch 4. This design enables automatic full inspection of the product, improving the quality of the parts.

[0025] The contact point here is a metal guide wheel, which limits the conditions for triggering indicator light 6. The triggering condition is set as follows: when the metal guide wheel approaches proximity switch 4 (i.e., the proximity sensor, which detects metal at a distance ≤2mm), proximity switch 4 is activated, outputting a low-level signal. This low-level signal is connected to the pass / fail indicator light 6, and the other end is connected to the positive terminal of the switching power supply 5, forming a circuit and illuminating indicator light 6). If the guide wheel is incorrectly installed, missing, or riveted in the wrong direction, the triggering condition of proximity switch 4 will not be met, and indicator light 6 will not illuminate.

[0026] The device in this application is mainly used for, for example Figure 2 The test piece 10 shown includes an upper connector 101 and a lower connector. The test content is whether the upper connector 101 and the lower connector 102 are perpendicular to each other after they are connected.

[0027] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
