[0025] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0026] This application provides a precision fitting fixture, which solves the problems of poor fitting accuracy and poor versatility of existing fixtures.

[0027] By setting the bonding groove 204 and the placement groove 301, the position of the material and the position of the product can be positioned to ensure that the material can be accurately bonded to the designated position of the product, effectively avoiding bonding offset and misalignment, improving bonding consistency and yield. At the same time, the mounting plate 2 and the pressing block 3 can be replaced according to the size and shape of the product or material, realizing the universality of the fixture and reducing the fixture replacement cost. The guide reset component prevents the pressing block 3 from tilting or getting stuck during the pressing process, ensuring stable bonding between the product and the material and improving the reliability of the operation.

[0028] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0029] Reference Figure 1 , Figure 2As shown, a precision fitting fixture includes: a base plate 1, a mounting block 101 mounted on the top of the base plate 1, a mounting plate 2 on the top of the mounting block 101, a pressing block 3 on the top of the mounting plate 2, a placement groove 301 on the top of the pressing block 3 for placing and positioning the product, and a slot 302 on the top of the pressing block 3; and a mounting assembly, disposed between the mounting plate 2 and the mounting block 101, for mounting and fixing the mounting plate 2, the mounting assembly including: mounting holes 102, openings 201, fixing holes 202, and fixing bolts 203, and multiple mounting holes 102 on the top of the mounting block 101. 2. The top of the mounting plate 2 has an opening 201, and a fixing hole 202 is opened inside the opening 201. A fixing bolt 203 passes through the fixing hole 202. The guide reset assembly is located between the pressing block 3 and the base plate 1 and is used to spring the pressing block 3 back to its original position. The guide reset assembly includes: a reset hole 303, a reset spring 304, a positioning rod 4 and a positioning hole 401. The bottom of the pressing block 3 has multiple reset holes 303. The reset spring 304 is connected inside the reset hole 303. The top of the base plate 1 is connected to the positioning rod 4. The bottom of the pressing block 3 has a positioning hole 401.

[0030] Combination Figure 4 As shown, the top of the mounting plate 2 has multiple bonding grooves 204 for placing materials so that the materials can be accurately bonded to the product later. The four corners of the bonding grooves 204 have corner grooves. The corner grooves serve as venting channels during the material placement process, allowing the gas between the material and the bonding grooves 204 to be discharged, thus preventing the formation of air bubbles between the material and the bonding grooves 204, which would prevent the material from being fully placed and affect the subsequent bonding.

[0031] Before using the fixture, install the mounting plate 2 corresponding to the shape of the material to be bonded onto the mounting block 101 using the mounting assembly. Then, install the pressing block 3 corresponding to the product onto the bottom plate 1 to complete the assembly of the fixture. When using it, place the material to be bonded into the bonding groove 204, then place the product into the placement groove 301, and then press the product so that the product moves the pressing block 3 down as a whole, so that the lower surface of the product can bond with the material inside the bonding groove 204. Then, the pressing block 3 and the product are returned to their original positions by the guide reset assembly, thus completing the process of bonding the material to the product.

[0032] Reference Figure 1 , Figure 2As shown, the mounting hole 102 corresponds to the fixing hole 202. The bottom end of the fixing bolt 203 extends through the fixing hole 202 and into the mounting hole 102. Place a suitable mounting plate 2 on the upper surface of the mounting block 101 and align the mounting plate 2 with the edge of the mounting block 101. At this time, the fixing hole 202 corresponds to the mounting hole 102, and the fixing bolt 203 can be screwed into the mounting hole 102 to connect the mounting plate 2 and the mounting block 101. At the same time, the opening 201 can accommodate the nut of the fixing bolt 203, preventing the fixing bolt 203 from protruding and causing the product to be unable to contact the material in the bonding groove 204, or even damaging the product surface.

[0033] Combination Figure 2 As shown, the placement groove 301 is connected to the slot 302. The cross-sectional size of the slot 302 is matched with the cross-sectional size of the mounting plate 2, so that the surface of the mounting plate 2 can be flush with the surface of the placement groove 301 during the downward movement of the pressing block 3, so that the lower surface of the product can contact and adhere to the material in the bonding groove 204.

[0034] Reference Figure 1 , Figure 3 and Figure 8 As shown, multiple reset holes 303 are symmetrically arranged and evenly distributed. The positioning rod 4 corresponds to the positioning hole 401, and the top end of the positioning rod 4 extends into the positioning hole 401 and is connected to a baffle. Multiple connecting holes 402 are provided on both sides of the pressing block 3, and the connecting holes 402 communicate with the positioning holes 401. A connecting bolt 403 passes through the connecting hole 402, and one end of the connecting bolt 403 extends into the positioning hole 401 and is located below the baffle.

[0035] During the bonding process, the product is pressed down, causing the pressing block 3 to move downwards together. At this time, the return spring 304 is compressed and accumulates elastic force. After bonding is completed, the pressure on the product is released. At this time, the pressing block 3 rebounds and resets under the action of the return spring 304, thereby separating the product from the mounting plate 2 and resetting it. During the downward movement of the pressing block 3, the positioning rod 4 and the positioning hole 401 can limit the movement direction of the pressing block 3, preventing the pressing block 3 from tilting and causing jamming or the product from being unable to fully bond with the material in the bonding groove 204, thus affecting the bonding effect.

[0036] When installing the pressing block 3, the pressing block 3 can be placed above the base plate 1, and the mounting block 101 can be aligned with the slot 302 so that the positioning rod 4 and the positioning hole 401 are in the same position. Then, the pressing block 3 is lowered so that the positioning rod 4 is inserted into the positioning hole 401. At this time, the pressing block 3 is supported by multiple return springs 304, and the baffle at the top of the positioning rod 4 is higher than the position of the connecting hole 402. Then, the connecting bolt 403 is screwed into the connecting hole 402, and one end of the connecting bolt 403 extends below the baffle to prevent the positioning rod 4 from falling out of the positioning hole 401, thus completing the installation of the pressing block 3.

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.
