Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a high-stability tooling and fixture for automotive interior inspection. Background Technology

[0002] High-stability tooling fixtures for automotive interior parts are specially designed tooling fixtures for inspecting automotive interior parts. They maintain the stability of automotive interior parts, facilitating their inspection. The fixtures allow for visual inspection, using gauges or calipers to check the shape and perimeter of the parts. Inspection pins or visual inspection can also be used to check holes for different purposes on the parts and the connection points between parts. This ensures rapid assessment of part quality during trial production and mass production, guaranteeing accuracy and production efficiency in the long-term production of automotive interior parts.

[0003] Existing high-stability tooling fixtures for automotive interior parts inspection mostly use fixing inserts or clamps to fix automotive interior parts. Although fixing inserts and clamps can fix automotive interior parts, they mostly tighten the automotive interior parts by rotating the screw to shorten the distance between the clamps. When the fixing inserts and clamps are not clamping the automotive interior parts, they need to maintain stability. However, the screw needs to be rotated repeatedly to push the clamps to tighten the automotive interior parts, which is very time-consuming and greatly increases the fixation time of automotive interior parts, reducing inspection efficiency. In order to solve this technical problem, this utility model proposes a high-stability tooling fixture for automotive interior parts inspection. Utility Model Content

[0004] The main objective of this invention is to provide a highly stable tooling fixture for automotive interior inspection, which can effectively solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A high-stability tooling fixture for automotive interior inspection includes a bracket. A slide rail is mounted on the upper surface of the bracket. Two sliders are slidably connected to the inner wall of the slide rail, and the two sliders are symmetrical. Two springs are installed inside the slide rail. A chuck is connected above each of the two sliders. A buffer pad is connected to one side of each of the two chucks. A push block is connected to the lower surface of the two sliders. A push head is provided outside the push block. An electric push rod is provided below the push head.

[0007] Preferably, the push block has an inclination angle, the push head has an inclination angle adapted to the push block, and the push head has a cavity inside to accommodate the push head. The fixed end of the electric push rod is connected to one side of the bracket, and the output end of the electric push rod is connected to the lower surface of the push block.

[0008] Preferably, the inner wall of the pusher is rotatably connected to multiple rollers, and the multiple rollers are arranged in an equidistant array, with the outer surface of the rollers in contact with the outer surface of the pusher block.

[0009] Preferably, the lower surface of the pusher is connected to two guide rods, which are symmetrical to each other, and the outer side of the bracket is connected to two sliding sleeves, which are symmetrical to each other, and the inner wall of the sliding sleeve is slidably connected to the outer surface of the guide rod.

[0010] Preferably, the inner wall of the slide is connected to a slide rod, and the outer surface of the slide rod is slidably connected to the inner wall of the slider.

[0011] Preferably, the inner wall of the slide is connected to a baffle, and the baffle is located in the middle of the slide.

[0012] Preferably, the two springs are sleeved on the outside of the slide rod, and the two springs are respectively located on both sides of the baffle. One end of each of the two springs is connected to one side of the baffle, and the other end of each of the two springs is connected to one side of the two sliders.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] In this invention, the cooperation between the clamps, push blocks, and push head, with an electric push rod as the power source, provides power for the movement of the push head. While the push head moves, the distance between the two push blocks changes. The push blocks drive the two clamps to move through the slider. When the distance between the two clamps decreases, they tighten and fix the automotive interior parts. When the two clamps move away from each other, they release the tightening and fixation of the automotive interior parts. This eliminates the need to repeatedly rotate the screw to change the distance between the clamps, thus improving the fixing efficiency of the tooling fixture for automotive interior parts.

[0015] In this invention, the cooperation between the guide rod, the sliding sleeve, the push head, and the roller, along with the two guide rods guiding the push head at its vertical position, ensures that the push head only moves vertically, preventing it from deviating from its direction and improving its stability. The roller has a rotation function, which reduces friction on the push block when it rotates and contacts it, making it easier to move the push block. Attached Figure Description

[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] like Figure 1-4 As shown, a high-stability tooling fixture for automotive interior inspection includes a bracket 1. A slide 2 is installed on the upper surface of the bracket 1. Two sliders 3 are slidably connected to the inner wall of the slide 2, and the two sliders 3 are symmetrical. The bracket 1 supports and mounts the required parts, and the slide 2 wraps around the sliders 3, supporting the sliders 3 and guiding their sliding direction.

[0023] Each of the two sliders 3 has a clamp 5 connected above it, and a buffer pad 6 is connected to one side of each clamp 5. The two clamps 5 can move closer to each other and further apart. By moving the two clamps 5 closer together, the interior parts of the car are tightened. By moving the two clamps 5 further apart, the interior parts of the car are released from being fixed. The buffer pad 6 is made of rubber. Rubber has good extensibility and can play a cushioning role to prevent the clamps 5 from being damaged when clamping the interior parts of the car.

[0024] The lower surfaces of the two sliders 3 are connected to push blocks 7. Push heads 8 are provided on the outside of push blocks 7. Electric push rods 9 are provided below push heads 8. The electric push rods 9 provide power to move the push heads 8. When the push heads 8 move, they push the push blocks 7 to retract inward. The electric push rods 9 are devices that convert the rotational motion of the electric motor into the linear reciprocating motion of the push rod. The electric push rods 9 include a drive motor, a reduction mechanism, a screw, and a nut. The electric push rods 9 have a self-locking function through the cooperation of various structures, which can maintain the stability of the push rod and prevent the push rod from shifting. After the clamps 5 tighten and fix the automotive interior parts, they have high stability.

[0025] The push block 7 has an inclination angle, the push head 8 has an inclination angle that matches the push block 7, and the push head 8 has a cavity inside to accommodate the push head 8. The fixed end of the electric push rod 9 is connected to one side of the bracket 1, and the output end of the electric push rod 9 is connected to the lower surface of the push block 7. By adjusting the inclination angles of the push block 7 and the push head 8, the push head 8 can change the position of the push block 7 when it moves.

[0026] Multiple rollers 10 are rotatably connected to the inner wall of the push head 8, and the multiple rollers 10 are arranged at equal intervals. The outer surface of the rollers 10 is in contact with the outer surface of the push block 7. The push head 8 contacts the push block 7 through the rotation of the rollers 10, which reduces friction on the push block 7 and makes it easier to move the push block 7 to a different position.

[0027] Two guide rods 11 are connected to the lower surface of the push head 8, and the two guide rods 11 are symmetrical. Two sliding sleeves 12 are connected to the outer side of the bracket 1, and the two sliding sleeves 12 are symmetrical. The inner wall of the sliding sleeve 12 is slidably connected to the outer surface of the guide rod 11. The sliding sleeve 12 wraps around the guide rod 11 to maintain the stability of the guide rod 11 when sliding. The guide rod 11 guides the push head 8 to move up and down, prevents the push head 8 from tilting, and maintains the stability of the push head 8.

[0028] The inner wall of the slide 2 is connected to a slide rod 13. The outer surface of the slide rod 13 is slidably connected to the inner wall of the slider 3. The slide rod 13 supports the slider 3 to improve its stability during sliding and guides the sliding direction of the slider 3.

[0029] The slide 2 is equipped with two springs 4 inside. The inner wall of the slide 2 is connected to a baffle 14, which is located in the middle of the slide 2. The baffle 14 provides support for the slide rod 13 to maintain its stability, and also provides support for the springs 4. The two springs 4 are sleeved on the outside of the slide rod 13, and are located on both sides of the baffle 14. One end of each spring 4 is connected to one side of the baffle 14, and the other end of each spring 4 is connected to one side of each of the two sliders 3. When the two sliders 3 contract, they compress the springs 4. The compressed springs 4 deform. After losing thrust outside the clamp 5, the springs 4 push the clamp 5 to move outward and reset, and the springs 4 return to their initial state.

[0030] It should be noted that in actual use, the car interior parts are first placed inside the two clamps 5. The electric push rod 9 is activated to push the push head 8 to move. Then, the push head 8 drives the roller 10 to move. The roller 10 pushes the push block 7 to move, and at the same time, the slider 3 drives the clamps 5 to move together. Then, the two clamps 5 tighten and fix the car interior parts. At the same time, the slider 3 moves and the spring 4 is compressed. After the car interior parts are inspected, the electric push rod 9 is activated again. The electric push rod 9 drives the roller 10 to disengage from the push block 7. At the same time, the spring 4 pushes the slider 3 to separate. The slider 3 drives the clamps 5 to separate, releasing the tightening and fixing of the car interior parts.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
