Description

Technical Field

[0001] This application relates to the technical field of test benches, and in particular to a modular carrier plate positioning multi-station test bench. Background Technology

[0002] A test bench is a specialized equipment platform used to test and experiment on various products, components, and materials to evaluate whether their performance, quality, and function meet relevant standards or expected requirements. It typically has a sturdy frame or platform to support the object being tested and ensure the stability of the entire device during the testing process.

[0003] In daily use, multiple test station workstations are typically set up to facilitate daily testing. However, in practice, these workstations are fixed, resulting in a large space occupation and hindering personnel movement when conducting a small number of tests. If only a few workstations are selected, a longer time is required for a large number of tests, which in turn affects the convenience of cleaning operations. Furthermore, the positioning parts of many test stations are fixedly integrated into the overall structure. When the type of product to be tested needs to be changed, especially when the product size, shape, interface position, etc., do not match the original positioning structure, it is often difficult to adjust the positioning parts individually. If the positioning parts are damaged, due to their fixed nature and strong correlation with the overall structure, troubleshooting, repairing, or replacing them is difficult and requires significant manpower, material resources, and time costs. During this period, the test station cannot be used normally, which will inevitably slow down the subsequent testing progress and reduce the overall testing efficiency. Utility Model Content

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0018] This application discloses a modular carrier plate positioning multi-station test bench. For example... Figure 1-6 As shown, the test platform includes a test bench body 1. Hidden grooves 2 are provided on both sides of the test bench body 1. Two expansion stations 3 are slidably fitted on the lower side of the inner wall of the hidden groove 2. A sliding opening 4 is provided on one side of the hidden groove 2. An L-shaped block 5 is slidably fitted on the inner wall of the sliding opening 4 and fixedly connected to the expansion station 3. A locking mechanism 6 is provided between the L-shaped block 5 and the test bench body 1.

[0019] Please see Figure 1 and Figure 6The locking mechanism 6 includes a movable opening 601 on the L-shaped block 5, a pin 602 that slides on the inner wall of the movable opening 601, multiple locking slots 603 on one side of the test platform 1 that cooperate with the pin 602, a fixed plate 604 fixedly connected to one end of the pin 602, and a tension spring 605 fixedly connected between the fixed plate 604 and the L-shaped block 5. When the expansion station 3 slides to the corresponding position, the tension spring 605 between the fixed plate 604 and the L-shaped block 5 pushes the pin 602 into the corresponding locking slot 603 on one side of the test platform 1, thereby locking the expansion station 3 to the test platform 1. To unlock, the pin 602 is pulled out by overcoming the tension spring 605.

[0020] The test platform 1 and the two extended workstations 3 are all provided with splicing grooves 7 on the upper side. The inner wall of the splicing groove 7 is fixedly connected with module plates 8. The upper side of the multiple module plates 8 is provided with positioning frames 9. The inner wall of the splicing groove 7 is provided with a fixing mechanism 10 that cooperates with the module plates 8. The lower side of the test platform 1 is provided with a support mechanism 11.

[0021] Please see Figure 2 and Figure 3 The fixing mechanism 10 includes a fixing groove 101 formed on one side of the inner wall of the splicing groove 7, a plug-in block 102 slidably fitted on the inner wall of the fixing groove 101, a spring 103 fixedly connected between the plug-in block 102 and the fixing groove 101, and a plug-in groove 104 formed on one side of the module plate 8 and fitted with the plug-in block 102. The fixing groove 101 is formed on one side of the inner wall of the splicing groove 7, and the plug-in block 102 can slide on the inner wall of the fixing groove 101. When installing the module plate 8, it is placed into the splicing groove 7. At this time, the plug-in block 102 will be inserted into the corresponding plug-in groove 104 on one side of the module plate 8 under the elastic force of the spring 103, thereby fixing the module plate 8. If it is necessary to disassemble the module plate 8, the plug-in block 102 can be pulled out by overcoming the elastic force of the spring 103.

[0022] Please see Figure 4 A support leg 12 is fixedly connected to the lower side of the cross block 113, and a soft pad 13 is fixedly connected to the lower side of the support leg 12. The support leg 12 fixed to the lower side of the cross block 113 is used to support the entire test platform 1. The soft pad 13 fixedly connected to its lower side can increase the friction with the placement surface, play an anti-slip role, and at the same time buffer the external impact of the test platform to ensure the stability of the test platform when it is placed.

[0023] Please see Figure 4The support mechanism 11 includes multiple hollow blocks 111 fixedly connected to the lower side of the test bench body 1, guide rods 112 slidably fitted on the inner wall of the hollow blocks 111, and a cross block 113 fixedly connected to the lower end of the multiple guide rods 112. The support mechanism 11 also includes a threaded sleeve 114 fixedly connected to the upper side of the cross block 113, a drive screw 115 rotatably fitted on the lower side of the test bench body 1 and threadedly fitted with the threaded sleeve 114, a worm gear 116 fixedly connected to the drive screw 115, a U-shaped frame 117 fixedly connected to the lower side of the test bench body 1, and a worm gear 116 rotatably fitted on the U-shaped frame 117. The worm 118, which is located on the inner wall of the frame 117 and meshes with the worm gear 116, drives the drive screw 115, which is fixed to the worm gear 116, to rotate by rotating the worm 118 inside the U-shaped frame 117 on the lower side of the test platform 1. Since the drive screw 115 is threadedly engaged with the threaded sleeve 114 on the upper side of the cross block 113, under the sliding guidance of multiple guide rods 112 and hollow block 111, when the drive screw 115 rotates, it causes the threaded sleeve 114 to drive the cross block 113 to move up and down along the guide rod 112, thereby realizing the adjustment of the height of the test platform 1.

[0024] Please see Figure 4 One end of the worm gear 118 extends to one side of the U-shaped frame 117 and is rotatably engaged. One end of the worm gear 118 is fixedly connected to a turntable 14. By rotating the turntable 14 fixedly connected to one end of the worm gear 118, the worm gear 118 can be driven to rotate, thereby driving the movement of related components that are threadedly engaged with the drive screw, thus realizing subsequent functions such as adjusting the height of the test platform 1.

[0025] The implementation principle of a modular carrier plate positioning multi-station test bench according to an embodiment of this application is as follows: In use, the extension station 3 can slide within the hidden grooves 2 on both sides of the test bench body 1. The sliding action is achieved through the cooperation of the L-shaped block 5 and the sliding port 4. The locking mechanism 6 is used for locking. When the extension station 3 slides into place, the insertion pin 602 is inserted into the corresponding locking groove 603 on one side of the test bench body 1 under the action of the tension spring 605, thereby fixing the extension station 3 to the test bench body 1 and ensuring that the extension station 3 can stably participate in the work. If the extension station 3 needs to be retracted, the insertion pin 602 can be pulled out to slide the extension station 3. The number of stations can be flexibly increased or decreased according to the actual testing needs. When large-scale testing or more test items are required, the extension station 3 can be unfolded for use to improve testing efficiency. When space or the amount of testing tasks is small, the extension station 3 can be retracted to save space and facilitate use and storage. A module board 8 is installed in the splicing slot 7 of the test bench body 1 and the expansion station 3. The fixing mechanism 10 is used to fix the module board 8. When installing the module board 8, it is placed into the splicing slot 7. The plug block 102 is inserted into the corresponding plug slot 104 on one side of the module board 8 under the action of the spring 103, so as to fix the module board 8. If the module board 8 needs to be replaced, the plug block 102 is pulled out to overcome the elastic force of the spring 103, so that the module board 8 can be removed. The module board 8 is fixed in the splicing slot 7, which makes the module board 8 easy to disassemble and replace. For different test objects, test items, etc., the appropriate module board 8 can be quickly replaced, which enhances the versatility and adaptability of the entire test bench and meets diverse test requirements. When height adjustment is required, the worm gear 118 is rotated by rotating the turntable 14. Since the drive screw 115 is threadedly engaged with the threaded sleeve 114, and the rotation of the drive screw 115 is stably transmitted through the meshing transmission of the worm wheel 116 and the worm gear 118, the threaded sleeve 114 can drive the cross block 113 to move up and down along the guide rod 112, thereby driving the support leg 12 to move up and down, changing the height of the test platform 1. The soft pad 13 on the underside of the support leg 12 can enhance the friction with the placement surface and play a buffering role, ensuring the stability of the test platform 1. The test platform can adapt to different operating environments, the height of operators, and the height matching requirements of different testing equipment, ensuring the comfort and convenience of testing operations.

[0026] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
