Consequently, product quality requirements may not be met, and measurement costs are increased. Examples include three copper busbars used in plastic coating. Figure 4 As shown, this is a product made of multiple hardware parts and steel sleeves during injection molding. The plastic material is PPS+GF20, and the shape is irregular with many holes and pillars. Under these circumstances, traditional measurement methods are difficult to meet the needs of efficient and accurate measurement. Utility Model Content

[0020] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Reference Figures 1 to 4 As shown, this utility model provides a simple measuring fixture for die-cutting parts. In one embodiment, it includes a base 1; a support block 2 is connected to the base 1, and a fixing seat 3 is also installed on the support block 2; a first through hole 31 extending to the other side is opened on one side of the fixing seat 3, and two first stops 32 are also installed on the bottom inner wall of the first through hole 31 on one side of the fixing seat 3; the top plane of one of the first stops 32 is flush with the bottom inner wall of the first through hole 31, and one end of the other first stop 32 extends to one side of the first through hole 31; a second stop 33 is also installed on one end of the fixing seat 3 near the first through hole 31, and one end of the second stop 33 extends toward the first through hole 31; a plurality of pads 34 are installed on the top and bottom of the other side of the fixing seat 3 near the first through hole 31, and one end of each pad 34 passes through the first through hole 31; a clamping and limiting component for clamping and limiting the product is also installed on one side of the fixing seat 3.

[0022] Continue to refer to Figure 4 As shown, this utility model targets a plastic-coated three-copper busbar, with the plastic material being PPS+GF20. During injection molding, multiple copper busbar hardware parts and steel sleeves are engraved. The product has irregular shapes, and there are many holes, posts, and dimensions, making measurement difficult and time-consuming. To improve measurement efficiency, facilitate repeated testing of multiple parts, and ensure testing accuracy, this utility model designs this measuring fixture. After computer programming, it can be used for three-dimensional measurement. The measuring fixture includes a base 1 (made of S50C), a support block 2 (made of S50C), a fixing seat 3 (made of aluminum alloy), a stop block, a pad block 34, a clamping and limiting component, etc. After the fixture is manufactured, it needs to be verified to be OK before it can be used.

[0023] Continue to refer to Figure 1-4 As shown, in this embodiment, the pad 34 has an L-shaped structure. The vertical end of the L-shaped pad 34 is fixedly connected to the other side of the fixing base 3, and the horizontal end of the L-shaped pad 34 passes through the first through hole 31. There are five pads 34: three at the bottom of the first through hole 31 and two at the top. Simultaneously, extension blocks extend inward from the inner walls of both ends of the first through hole 31, and each extension block is equipped with an adjusting screw 38 along the depth direction of the first through hole 31. Figure 1As shown, after placing the plastic-coated three-copper busbar product on the measuring fixture, the three stops cooperate to achieve X and Y direction positioning of the product, while the five pads 34 and two adjusting screws 38 can achieve Z direction positioning of the product. The product is then clamped and fixed by the clamping and limiting assembly. After the product is clamped, the X / Y / Z reference is determined by taking the corresponding reference hole position (the waist-shaped hole on the left side of the product is the Y-direction reference hole, the round hole on the right side of the product is the X-direction reference hole, and the plane where the steel sleeve on the product is located is the Z-axis reference plane) and the surface. Then, the corresponding dimensions are measured according to the inspection program to ensure the normal operation of the product inspection.

[0024] In one embodiment, the clamping and limiting assembly includes a plurality of guide rods 35 mounted on one side of the fixing base 3, and the plurality of guide rods 35 are arranged around the first through hole 31; each guide rod 35 is equipped with an elastic clip, and one end of the elastic clip extends into the first through hole 31. (Continuing to refer to...) Figure 2 As shown, in this embodiment, there are 10 guide rods 35, with 2 on the upper part and 6 on the lower part of one side of the fixing seat 3, and 1 at each of two opposite corners on one side of the fixing seat 3. The elastic clamp includes a sliding block 36 movably sleeved on the guide rod 35, and an elastic pressure plate 37 integrally connected to one end of the sliding block 36 and extending into the first through hole 31. After the product is placed, the sliding block 36 is pressed down, and the elastic pressure plate 37 presses and fixes the product. To prevent product compression, a buffer pad is provided at the bottom of the end of the elastic pressure plate 37 used to press and limit the product. Furthermore, the top of the support block 2 has an L-shaped mounting slot, and the fixing seat 3 is arranged in the mounting slot. A locking screw 21 is installed at the vertical end of the L-shaped mounting slot to lock and fix the fixing seat 3. The fixing seat 3 can be quickly and easily locked onto the support block 2 with the screw, making assembly convenient.

[0025] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
