[0002] After the automotive pump handle is manufactured, the choice of inspection methods for quality control is a key consideration for enterprises. Currently, the most commonly used tool for parts inspection is the coordinate measuring machine (CMM). This tool is widely used due to its high precision and intelligence; however, it is time-consuming and inefficient, making it unsuitable for mass production. Operators of CMMs must invest significant time and effort to complete the work quickly and accurately, adding intangible costs to the enterprise. Such inspection instruments are unsuitable for parts requiring rapid and multi-directional inspection in large-scale production. General measuring tools, on the other hand, often fail to reflect the true condition of the product, frequently resulting in misjudgments and failing to meet on-site production requirements. To address this issue, our company has invented and designed a dedicated inspection tool for pump handles. Therefore, the purpose of this invention is to provide a simple, inexpensive inspection tool that can quickly determine the quality of automotive pump handles, solving the aforementioned problems.

[0037] Reference Figure 1 In this embodiment, the car Pump handle 16 includes a handle operating part 161 and a handle mounting part 162 connected to each other. The bottom surface of the handle mounting part 162 is lower than the bottom surface of the handle operating part 161. The handle mounting part 162 has a main positioning hole 163 and a secondary positioning hole 164 for mounting and positioning, as well as a positioning through hole 165 to be detected and a profile.

[0038] Reference Figure 2-5 This utility model provides a gauge for a car pump handle, comprising:

[0039] Base plate 1;

[0040] The detection block 8 is fixed on the base plate 1. The detection block 8 has a placement groove 3 that is adapted to the car Pump handle 16. The placement groove 3 is divided into an operation part support section 31 and a mounting part support section 32. The depth of the mounting part support section 32 is greater than the depth of the operation part support section 31.

[0041] The main positioning pin 4 is inserted into the operating part support section 31 and is adapted to the main positioning hole 163 of the car Pump handle 16.

[0042] The secondary positioning pin 5 is inserted into the operating part support section 31 and is adapted to the secondary positioning hole 164 of the car Pump handle 16.

[0043] A clamping device (6,7) is provided on the base plate 1 for clamping and fixing the car Pump handle 16 in the placement groove 3;

[0044] The active detection pin 9 is inserted into the operating part support section 31 and is used to detect whether the positioning through hole 165 of the car Pump handle 16 is qualified.

[0045] Several profile go / no-go gauges (10, 11, 12) are used to check whether the profile of the automobile Pump handle 16 is up to standard.

[0046] It should be noted that the operating part support section 31 has holes corresponding to the main positioning pin 4, the secondary positioning pin 5 and the movable detection pin 9, so the main positioning pin 4, the secondary positioning pin 5 and the movable detection pin 9 can all be inserted into the operating part support section 31.

[0047] When using this inspection tool, the specific steps are as follows: 1) Open all clamping devices and pull out all locating pins (including main locating pin 4 and secondary locating pin 5) and movable detection pin 9, so that the entire inspection tool is in a non-working state; 2) Place the car Pump handle 16 on the placement groove 3, with the bottom surface of the placement groove 3 serving as the locating surface. The surface of the part must be clean, free of oil stains and obvious burrs; 3) According to the operation manual, correctly position the car Pump handle 16 with its bottom surface against the locating surface. Insert the main locating pin 4 and secondary locating pin 5 into the main locating hole 163 and secondary locating hole 164 of the car Pump handle 16 and close the clamping devices to confirm that the car Pump handle 16 will not move; 4) Use the movable detection pin 9 to check the locating through hole 165; 5) Use several profile gauges to check the corresponding profile of the car Pump handle 16; 6) After the inspection is completed, open the clamping devices, pull out the main locating pin 4, secondary locating pin 5 and movable detection pin 9, remove the car Pump handle 16, and then restore all parts of the inspection tool to their original positions.

[0048] This invention places the car pump handle 16 on the placement groove 3, and uses the placement groove 3, the main positioning pin 4, and the secondary positioning pin 5 as the positioning reference for the car pump handle 16 to ensure the accuracy of the car pump handle 16's position. Then, a clamping device is used to press the car pump handle 16 tightly to prevent the car pump handle 16 from shifting. After positioning, the positioning through hole 165 and the profile of the car pump handle 16 can be inspected by using the movable detection pin 9 and several profile go / no-go gauges. The operation is simple and inexpensive, and it can quickly determine whether the positioning through hole 165 and the profile of the car pump handle 16 are qualified, improving measurement efficiency and reducing measurement costs.

[0049] It should be noted that using the active detection pin 9 and the surface go / no-go gauge to detect the positioning through hole 165 and the surface profile of the car Pump handle 16 is a conventional technical means in this field. Specifically, in this embodiment, the part is judged to be qualified when the go end of the surface go / no-go gauge can be inserted but the no-go end cannot be inserted and the active detection pin 9 can be fully inserted into the positioning through hole 165; otherwise, it is unqualified.

[0050] As a preferred implementation scheme, refer to Figure 3-5 The placement slot 3 has no sidewall on one side, making it easy to insert the car Pump handle 16.

[0054] As a preferred embodiment, there are two clamping devices located on the base plate 1 near the mounting support section 32. The front end of the clamping clamp 6 is U-shaped, which can press down along the main locating pin 4 and the auxiliary locating pin 5. The clamping position is around the main locating pin 4 and the auxiliary locating pin 5. The main and auxiliary locating pins are the core references that restrict the X / Y movement and Z rotation of the part. There is a small gap between the part and the reference hole (to ensure assemblability). The clamping force is applied directly to the periphery of the locating pin. It can "press" the part against the reference surface of the locating pin through the rigid area around the reference hole of the part, completely eliminating the radial gap between the hole and the pin, preventing the part from rotating around the locating pin or moving along the pin axis, and ensuring that the part is completely in contact with the locating reference.

The first detection pin 91 includes a first detection block 911, one end of which is fan-shaped and matches the fan-shaped segment in the middle of the positioning through hole 165. A first insertion pin 912 is fixedly inserted into the first detection block 911 and is used to insert into the operating part support section 31. The second detection pin 92 includes a second detection block 921, which is circular and matches the arc-shaped segments on both sides of the positioning through hole 165. A second insertion pin 922 is fixedly inserted into the second detection block and is used to insert into the operating part support section 31. The first detection pin 91 and the second detection pin 92 are used independently for detection. The operating part support section 31 has holes corresponding to the first insertion pin 912 and the second insertion pin 922.
