[0002] Product testing is a crucial step before products leave the factory. Traditional clamping mechanisms have relatively poor repeatability. In automated testing, accurate and repeated positioning of products is a key indicator that directly affects testing results and efficiency. Therefore, we designed an automatic centering clamping mechanism that uses a linkage mechanism to ensure repeatability and positioning accuracy, enabling efficient positioning tasks.

[0005] Preferably, the drive propulsion assembly includes a fixing strip fixedly connected to the bottom of the T-shaped plate, a fixing rod fixedly connected to one side of the fixing strip, a sliding tube slidably connected to the surface of the fixing rod, and a spring sleeved on the surface of the fixing rod, with the two ends of the spring fixedly connected to the fixing strip and the sliding tube respectively.

[0006] Preferably, the bottom of the pre-clamp plate is fixedly connected to a sliding plate sleeved on the surface of the sliding tube, the sliding plate is slidably connected to the surface of the sliding tube, and a second spring is sleeved on the surface of the sliding tube, the two ends of the second spring being fixedly connected to the sliding tube and the sliding plate respectively.

[0009] Preferably, a rubber pad is adhered to one side of both the pre-clamping plate and the fixed clamping plate.

[0010] The beneficial effects of this utility model are:

[0011] 1. This utility model uses a drive propulsion component to move two T-shaped plates toward each other, thereby causing two pre-clamping plates to pre-clamp the product. The T-shaped plates continue to move due to the drive propulsion component. During this time, the T-shaped plates pull the sliding sleeve through the connecting rod, causing the fixed clamping plate on the sliding sleeve to clamp the product from front to back. This achieves a mechanism driven by a linkage mechanism that ensures repeatability and positioning accuracy, enabling efficient positioning tasks.

[0012] 2. By setting a guide rail, the sliding sleeve will slide on the surface of the guide rail during the movement of the sliding sleeve, which provides guidance and limit for the movement of the sliding sleeve and improves the stability of the movement of the sliding sleeve and the fixed clamp.

[0013] 3. By setting a rubber pad, the rubber pad will come into contact with the product first when the fixed clamp and pre-clamp are in contact with the product, thus protecting the product to a certain extent and avoiding scratches on the product surface. Attached Figure Description

Detailed Implementation

[0020] In the following description, embodiments of the automatic centering clamping mechanism of the present invention will be described with reference to the accompanying drawings.

[0021] Figure 1-3 This invention illustrates an embodiment of an automatic centering clamping mechanism, comprising a support plate 1, movable T-shaped plates 2 on both sides of the bottom of the support plate 1, a pre-clamping plate 3 fixedly mounted at the top end of the T-shaped plates 2, rectangular openings 4 for the pre-clamping plates 3 to move on both sides of the top of the support plate 1, a movable sliding sleeve 5 at the bottom of the support plate 1, four guide rails 11 fixedly mounted at the bottom of the support plate 1, the sliding sleeve 5 slidably connected to the surface of the guide rails 11, and a fixed clamping plate 6 fixedly mounted at the top end of the sliding sleeve 5. Through the guide rails 11, the sliding sleeve 5 slides on the surface of the guide rails 11 during movement, providing guidance and limiting for the movement of the sliding sleeve 5, improving the stability of the movement of the sliding sleeve 5 and the fixed clamping plate 6. Rubber pads are adhered to one side of both the pre-clamping plate 3 and the fixed clamping plate 6. Through the rubber pads, when the fixed clamping plate 6 and the pre-clamping plate 3 come into contact with the product, the rubber pads will contact the product first, providing some protection to the product and preventing scratches on the product surface. The bottom of plate 5 is fixedly connected to a pivot pin 7. Two symmetrical pivot pins 8 are fixedly connected to the bottom end of plate 2. A connecting rod 9 is sleeved on the surface of pivot pins 7 and 8. Drive propulsion assemblies 10 are provided on both sides of the bottom of the support plate 1. Each drive propulsion assembly 10 includes a fixing strip 101 fixedly connected to the bottom of plate 2. A fixing rod 102 is fixedly connected to one side of the fixing strip 101. A sliding tube 103 is slidably connected to the surface of the fixing rod 102. A spring is sleeved on the surface of the fixing rod 102. 104, the two ends of spring 104 are fixedly connected to the fixing strip 101 and the slide tube 103 respectively. The bottom of the pre-clamping plate 3 is fixedly connected to a sliding piece 105 sleeved on the surface of the slide tube 103. The sliding piece 105 is slidably connected to the surface of the slide tube 103. Spring 2 106 is sleeved on the surface of the slide tube 103. The two ends of spring 2 106 are fixedly connected to the slide tube 103 and the sliding piece 105 respectively. Cylinder 107 is fixedly installed at the bottom of the bearing plate 1. The output end of cylinder 107 is fixedly installed with the slide tube 103.

[0022] Working principle: When using this utility model, the product is placed on top of the support plate 1. The two springs 106 extend simultaneously, which pushes the slide tube 103 to move. The slide tube 103 slides on the surface of the fixing strip 101. During the movement of the slide tube 103, the springs 106 pull the slide plate 105. The slide plate 105 then drives the pre-clamping plate 3 to move until the pre-clamping plate 3 contacts the product. The two pre-clamping plates 3 achieve pre-clamping of the product. The slide tube 103 continues to move, which compresses the spring 104. The restoring force of the spring 104 presses against the fixing strip 101, thereby driving the T-shaped plate 2 to move. The T-shaped plate 2 then pulls the connecting rod 9 through the shaft pin 8. The connecting rod 9 rotates on the surface of the shaft pin 7, which pulls the sliding sleeve 5 to slide on the surface of the guide rail 11. The four sliding sleeves 5 drive the four fixing plates 6 to move towards the center to fix the product front and back.

[0023] In summary, this automatic centering clamping mechanism, through the drive propulsion component 10, causes the two T-shaped plates 2 to move towards each other, thereby causing the two pre-clamping plates 3 to pre-clamp the product. The T-shaped plates 2 continue to move due to the drive propulsion component 10. During this process, the T-shaped plates 2 pull the sliding sleeve 5 through the connecting rod 9, causing the fixed clamping plate 6 on the sliding sleeve 5 to clamp the product from front to back. This achieves a mechanism driven by a linkage mechanism that ensures repeatability and positioning accuracy, enabling efficient positioning tasks.
