Description

Technical Field

[0001] This utility model relates to the field of testing tool technology, specifically to a rapid inspection tool structure for determining the outer clamp of a fixed clamp back plate. Background Technology

[0002] The outer clamp of the brake backplate is a core dimension for the installation of brake pads and calipers. Deviations in this dimension can cause problems such as dragging, vibration, and abnormal noise during braking. Furthermore, the outer clamp length of the fixed caliper is typically 40mm to 60mm, which is 2 to 3 times the length of the outer clamp of the floating caliper. As a core dimension, its manufacturing tolerance requirement is ±0.05, and the engineering capability requirement is Cpk 1.67 or higher. Customers usually require 100% inspection control.

[0003] Orders for this type of backplate typically range from 180,000 to 200,000 pieces per month, with a gradually increasing trend. Because full inspection is required, the efficiency of traditional external card inspection tools for floating clamps averages 5 to 6 seconds per piece, while the efficiency for fixed clamps averages 12 to 15 seconds per piece. Based on a standard production of 12,000 pieces per shift, 4 to 5 people are needed to perform full inspection of the external cards using fixed clamps to complete the shift's production target. Summary of the Invention

[0004] This invention addresses the shortcomings of existing technologies by providing a rapid inspection fixture structure for determining the size of the outer clamp of a fixing clamp back plate. This structure is characterized by its simple structure, convenient operation, and high efficiency. It enables rapid determination of the outer clamp size of the fixing clamp back plate, improving production efficiency and preventing defective products from leaving the factory.

[0005] The above-mentioned technical problems of this utility model are mainly solved by the following technical solutions:

[0006] A quick inspection fixture structure for determining the external clamping of a fixed clamp backplate includes a brake backplate and an inspection fixture base. The inspection fixture base is provided with a slider for placing the brake backplate. The front end of the slider is provided with a pair of positioning posts that are inserted into the brake backplate. A main guide rail is provided between the slider and the inspection fixture base, which is slidably inserted into the slider. A pair of go gauge limit blocks are provided at the rear ends of both sides of the slider. Each of the go gauge limit blocks is provided with a no-go gauge limit block at its front end.

[0007] The stop gauge limit blocks are located on both sides of the end of the main guide rail. The dimension between the stop gauge limit blocks is the upper limit dimension of the brake backplate. When the product enters the stop gauge limit block, it means that the outer clamp of the brake backplate has exceeded the upper limit dimension, and the stop gauge is unqualified.

[0008] The go gauge limit blocks are located on both sides of the middle of the main guide rail. The dimension between the go gauge limit blocks is the lower limit dimension of the brake backplate. If the product cannot pass through the go gauge limit blocks completely, it means that the outer clamp of the brake backplate has exceeded the lower limit dimension, and the brake backplate is unqualified.

[0009] Preferably, the main guide rail is provided with an auxiliary guide rod that is slidably sleeved with the slider, and both ends of the auxiliary guide rod are provided with guide rod seats that are screwed and fixed to the fixture base.

[0010] Preferably, a limiting post is provided between the end of the main guide rail and the guide rod seat.

[0011] Preferably, the four corners of the lower end of the inspection fixture base are provided with shock-absorbing pads that are screwed and fixed to the inspection fixture base.

[0012] Preferably, the base of the inspection tool is provided with handles on both sides.

[0013] This invention can achieve the following effects:

[0014] This invention provides a rapid inspection fixture structure for determining the outer dimensions of a fixed clamp backplate. Compared with existing technologies, it features a simple structure, convenient operation, and high efficiency. It enables rapid determination of the outer dimensions of the fixed clamp backplate, improving production efficiency and preventing defective products from leaving the factory.

[0015] Simulated testing: The actual positioning and movement of the product are simulated using sliders and positioning pins.

[0016] Highly efficient judgment: Adopting the classic "go / no" principle, the dimensional measurement is simplified to a quick "yes / no" judgment, which greatly improves the inspection efficiency and is very suitable for mass quality inspection on the production line.

[0019] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.

[0020] Example: Figure 1As shown, a quick inspection fixture structure for determining the external clamping of a fixed clamp backplate includes a brake backplate 5 and a fixture base 7. Each of the four corners of the lower end of the fixture base 7 is provided with shock-absorbing pads 8 that are screwed and fixed to the fixture base 7. Handles 11 are provided on both sides of the fixture base 7. A slider 6 for placing the brake backplate 5 is provided on the fixture base 7. A pair of positioning posts 9 that insert into the brake backplate 5 are provided at the front end of the slider 6. A main guide rail 12 that slides into the slider 6 is provided between the slider 6 and the fixture base 7. An auxiliary guide rod 3 that slides into the slider 6 is provided on the side of the main guide rail 12. Guide rod seats 2 that are screwed and fixed to the fixture base 7 are provided at both ends of the auxiliary guide rod 3. A limiting post 1 is provided between the end of the main guide rail 12 and the guide rod seat 2. A pair of go gauge limiting blocks 10 are provided at the rear ends of both sides of the slider 6. A no-go gauge limiting block 4 is provided at the front end of each go gauge limiting block 10.

[0021] Working principle: Place the brake backplate 5 on the raised positioning planes on both sides of the slider 6, ensuring the head plane of the brake backplate 5 is in full contact with the positioning post 9. Press down on the brake backplate 5 with one hand and push it forward. As the slider 6 moves forward on the main guide rail 12, it passes through the go gauge limit block 10 and stops before reaching the stop gauge limit block 4. In this case, the brake backplate 5 is deemed qualified.

[0022] If the brake backplate 5 does not completely pass through the go gauge limit block 10, or if it gets stuck in contact with the go gauge limit block 10, the product is deemed unqualified; if the brake backplate 5 does not stop in front of the stop gauge limit block 4, and enters or completely passes through the stop gauge limit block 4, the brake backplate 5 is deemed unqualified.

[0023] In summary, this rapid inspection fixture structure for determining the dimensions of the fixing clamp backplate is characterized by its simple structure, convenient operation, and high efficiency. It enables rapid determination of the dimensions of the fixing clamp backplate, improving production efficiency and preventing defective products from leaving the factory.
