This reduces costs and shortens test preparation time, and is widely used in the quality inspection of batch and multi-category products.

[0003] However, the existing testing fixtures have fixed PIN test block positions during use, making it difficult to adjust them flexibly. This makes it inconvenient to test products of different sizes and shapes, reducing the versatility of the device. Utility Model Content

[0004] The purpose of this utility model is to provide a universal testing fixture for various product forms. By setting up a detection unit, it solves the problem that existing testing fixtures have fixed PIN test block positions during use, making it difficult to flexibly adjust them, which is inconvenient for testing products of different sizes and shapes, and reduces the versatility of the device.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a universal testing fixture for various product forms, including a base plate and several support legs fixedly connected to the bottom of the base plate. It also includes: a detection unit mounted on the top of the base plate; an installation unit mounted on the top of the base plate; the detection unit includes an installation assembly disposed on the base plate; and a moving assembly mounted on the installation assembly. The installation assembly includes a first fixing block fixedly connected to the top of the base plate, a moving plate slidably connected to the inner wall of the first fixing block, a second fixing block fixedly connected to the top of the base plate, two limiting blocks fixedly connected to the top of the base plate, and two sliders fixedly connected to the top of the base plate; wherein the two sliders are disposed below the moving plate.

[0007] Furthermore, the mounting part includes a connecting component mounted on the top of the base plate; and a pressing component mounted on the connecting component; wherein the pressing component is disposed within the connecting component.

[0008] Furthermore, the moving component includes a moving block disposed on the top of the base plate, two sliders passing through the moving block and slidably connected to the outer wall of the moving block, a hydraulic cylinder fixedly connected between the two limiting blocks, the hydraulic cylinder passing through the two limiting blocks, a connecting block one fixedly connected to the bottom of the moving block, the output shaft of the hydraulic cylinder fixedly connected to the connecting block one, and a pressing element disposed on the moving block; wherein, the hydraulic cylinder provides the necessary power output for the movement of the moving block.

[0009] Furthermore, the connecting assembly includes a processing box fixedly connected to the top of the base plate. A connecting plate is fixedly connected to the top inner wall of the processing box. A support block is fixedly connected to the bottom of the connecting plate. A working plate is fixedly connected to the bottom of the support block. An mounting block is fixedly connected to the top of the base plate. The top of the mounting block is fixedly connected to the working plate. Several support rods are fixedly connected to the bottom of the base plate. The tops of the several support rods are all fixedly connected to the working plate. There are four support rods, which are linearly distributed and fixed to the bottom of the working plate.

[0010] Furthermore, the pressing assembly includes a cylinder fixedly connected to the bottom of the working plate, the output shaft of the cylinder being fixedly connected to the pressing plate, and a detection element being provided on the pressing plate.

[0011] Furthermore, the extrusion component includes an extrusion block fixedly connected to the bottom of a fixed block one, a spring fixedly connected to the rear side of the extrusion block, the side of the spring away from the extrusion block fixedly connected to a fixed block two, and a PIN test block fixedly connected to the top of the movable block; wherein, the spring is in a stretched state under natural conditions.

[0012] Furthermore, the detection device includes a Hall effect programming probe fixedly connected to the lower pressure plate.

The test probes are adapted to the PIN test pins on the PIN test block.

[0013] This utility model has the following beneficial effects:

[0014] 1. By setting up a detection unit, after the hydraulic cylinder is started, its output shaft pulls the moving block through connecting block one, causing the moving block to slide smoothly along the two sliders. During the movement, the moving block synchronously drives the pressing block to move towards the fixed block two, thereby compressing the spring. The spring effectively buffers the tension of the hydraulic cylinder during this process. Finally, the moving block drives the PIN test block to gradually reach the preset appropriate position. When conducting product testing, the position of the PIN test block can be flexibly adjusted, avoiding the fixed position of the PIN test block, which would be inconvenient for testing products of different sizes and shapes, thus improving the versatility of the device.

[0015] 2. By setting up the mounting section, after the PIN test block reaches the designated position, the cylinder starts and drives the lower platen to move downward, causing the test probe and Hall effect programming probe to synchronously approach the PIN test block. Before contact, the system pre-programs the Hall effect programming probe. When the lower platen continues to descend until the test probe contacts the PIN test pin on the PIN test block, the test data is immediately fed back to the control system through the probe group. During product testing, this provides a stable test frame, avoids deviations in test results due to vibration during the test, and improves the stability of product testing.

[0016] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0027] 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.

[0028] Please see Figure 1-7 As shown, this utility model is a test fixture that can be used for various product forms, including a base plate 111 and a number of support legs 112 fixedly connected to the bottom of the base plate 111, and also includes a detection unit 2, which is installed on the top of the base plate 111.

[0029] Mounting part 3 is mounted on the top of base plate 111. Detection part 2 includes mounting assembly 21, which is disposed on base plate 111; and moving assembly 22, which is mounted on mounting assembly 21. Mounting assembly 21 includes a fixing block 211 fixedly connected to the top of base plate 111, a moving plate 212 slidably connected to the inner wall of fixing block 211, a fixing block 213 fixedly connected to the top of base plate 111, two limiting blocks 214 fixedly connected to the top of base plate 111, and two sliders 215 fixedly connected to the top of base plate 111. Two sliders 215 are positioned below the movable plate 212. The movable assembly 22 includes a movable block 221 positioned on top of the base plate 111.

A connecting block 223 is fixedly connected to the bottom of the movable block 221, and the output shaft of the hydraulic cylinder 222 is fixedly connected to the connecting block 223. An extrusion member is provided on the movable block 221. The hydraulic cylinder 222 provides the necessary power output for the movement of the moving block 221. The extrusion component includes an extrusion block 224 fixedly connected to the bottom of the first fixed block 211. A spring 225 is fixedly connected to the rear side of the extrusion block 224. The side of the spring 225 away from the extrusion block 224 is fixedly connected to the second fixed block 213. A PIN test block 226 is fixedly connected to the top of the moving block 221. The spring 225 is in a stretched state under natural conditions. By setting the detection unit 2, after the hydraulic cylinder 222 is started, its output shaft pulls the moving block 221 through the first connecting block 223, causing... The moving block 221 slides smoothly along the two sliders 215. During the movement, the moving block 221 simultaneously drives the pressing block 224 to move towards the fixed block 213, thereby pressing the spring 225. During this process, the spring 225 effectively buffers the tension of the hydraulic cylinder 222. Finally, the moving block 221 drives the PIN test block 226 to gradually reach the preset appropriate position. When conducting product testing, the position of the PIN test block 226 can be flexibly adjusted to avoid the PIN test block being fixed in position, which would make it inconvenient to test products of different sizes and shapes, thus improving the versatility of the device.

[0030] The mounting section 3 includes a connecting assembly 31, which is mounted on the top of the base plate 111; and a pressing assembly 32, which is mounted on the connecting assembly 31. The pressing assembly 32 is disposed within the connecting assembly 31. The connecting assembly 31 includes a processing box 311 fixedly connected to the top of the base plate 111. A connecting plate 312 is fixedly connected to the inner top wall of the processing box 311. A support block 313 is fixedly connected to the bottom of the connecting plate 312. A working plate 314 is fixedly connected to the bottom of the support block 313. The top of the base plate 111... A mounting block 315 is fixedly connected to the base plate 314. The top of the mounting block 315 is fixedly connected to the working plate 314. Several support rods 316 are fixedly connected to the bottom of the base plate 311, and the tops of the support rods 316 are all fixedly connected to the working plate 314. There are four support rods 316, which are linearly distributed and fixed to the bottom of the working plate 314. The pressing assembly 32 includes a cylinder 321 fixedly connected to the bottom of the working plate 314. The output shaft of the cylinder 321 is fixedly connected to a pressing plate 322, and a detection element is provided on the pressing plate 322. The testing component includes a Hall effect probe 323 fixedly connected to a lower pressure plate 322. A connecting block 324 is fixedly connected to the bottom of the lower pressure plate 322. Several test probes 325 pass through the connecting block 324, and the inner walls of the test probes 325 are fixedly connected to the connecting block 324. The test probes 325 are adapted to the PIN test pins on the PIN test block 226. After the PIN test block 226 reaches the designated position by setting the mounting part 3, the cylinder 321 is activated and drives the lower pressure plate 322 to move downward. The system drives the test probe 325 and Hall effect programming probe 323 to approach the PIN test block 226 simultaneously. Before contact, the system prepares the Hall effect programming probe 323 for programming. When the pressure plate 322 continues to descend until the test probe 325 contacts the PIN test pin on the PIN test block 226, the test data is immediately fed back to the control system through the probe group. During product testing, this provides a stable test frame and avoids deviations in test results due to vibration during the test, thereby improving the stability of product testing.

[0031] A specific application of this embodiment is as follows: In use, the hydraulic cylinder 222 is activated, and the output shaft of the hydraulic cylinder 222 pulls the moving block 221 along the two sliders 215 through the connecting block 1 223. When the moving block 221 moves, it drives the pressing block 224 to move towards the fixed block 213, pressing the spring 225. The spring 225 buffers the pulling force of the hydraulic cylinder 222 until the moving block 221 drives the PIN test block 226 to the appropriate position. After the PIN test block 226 has moved, the cylinder 321 is activated, and the cylinder 321 drives the lower pressure plate 322 to move. The lower pressure plate 322 drives the test probe 325 to move. Under the movement of the lower pressure plate 322, the test probe 325 and the Hall effect programming probe 323 gradually approach the PIN test block 226. Before approaching, the Hall effect programming probe 323 is programmed. When the test probe 325 contacts the PIN test pin on the PIN test block 226, the test data is fed back, and the test is completed.
