Description

Technical Field

[0001] This application relates to the field of product fixtures, and particularly to a hydrolysis glue bonding and precision carving positioning tooling. Background Art

[0002] Precision carving alignment tooling is widely used in various fields that require high-precision machining, such as aerospace, automotive manufacturing, mold manufacturing, electronic product manufacturing, etc. In these fields, the precision and surface quality of workpieces often have an important impact on the overall performance and service life of products. Therefore, using precision carving alignment tooling for machining can significantly improve the machining precision and surface quality of products. With the enhancement of environmental awareness, the use of traditional mechanical machining tooling faces challenges in terms of environmental protection.

[0003] For example, in the patent application No. CN202221564226.0, a wire cutting positioning tooling is disclosed, which includes a plate positioning tooling. Above the plate positioning tooling, there is a cutting plate, and the cutting plate is in fitting connection with the plate positioning tooling. On the outside of the plate positioning tooling, there are rubber screw buttons, and the rubber screw buttons are rotationally connected to the plate positioning tooling through internal threads. On one side of the cutting plate, there is a first positioning seat shaft, and on the adjacent side of the first positioning seat shaft, there is a second positioning seat shaft. The following are the deficiencies of the above device during actual use:

[0004] This device uses the first positioning seat and the second positioning seat to position a single module through mechanical machining. However, during the positioning process, the first positioning seat and the second positioning seat are in use, resulting in the inability to synchronously fix multiple modules, reducing the positioning efficiency. At the same time, the metal material of the tooling used has high VOC emissions, which affects the environmental protection requirements of the manufacturing industry. Summary of the Utility Model

[0005] In order to improve the problem that the use of high-VOC-emission materials in conventional positioning tooling affects environmental protection and at the same time cannot position multiple modules, reducing efficiency, this application provides a hydrolysis glue bonding and precision carving positioning tooling.

[0006] The hydrolysis glue bonding and precision carving positioning tooling provided by this application adopts the following technical solutions:

[0007] A hydrolysis glue bonding and precision carving positioning tooling includes a bottom plate. On the surface of the bottom plate, there are multiple modules inserted for precision carving. On the top of the multiple modules, there is a cover plate. At the positions of the multiple modules on the bottom of the cover plate, positioning columns are fixedly provided. At the bottom of the multiple positioning columns, there are adhesive layers, and the bottom of the multiple adhesive layers is connected to the modules. The vertically aligned multiple positioning columns and the modules are integrally fixedly connected.

[0008] There are multiple stud bolts threadedly arranged between the bottom plate and the cover plate, and nuts are provided on the opposite sides of the bottom plate and the cover plate for the multiple stud bolts.

[0009] By adopting the above technical solution, the positioning posts are inserted into the positioning holes, so that the adhesive layer is bonded and fixed to the module, and the nut rotates at the bottom of the stud to push the bottom plate and the cover plate to clamp, continuously maintaining the fixing effect of the adhesive layer and the module, and multiple modules can be fixed synchronously.

[0010] Preferably, positioning holes are formed on the surface of the bottom plate at the positions of multiple modules, and the inner walls of the multiple positioning holes are inserted into the multiple modules one by one.

[0011] By adopting the above technical solution, the module is inserted into the positioning hole to form a horizontal fixation. At the same time, the positioning hole is aligned with the positioning post, guiding the insertion of the positioning post.

[0012] Preferably, ventilation grooves are communicated and formed between adjacent ones of the multiple positioning holes.

[0013] By adopting the above technical solution, the ventilation grooves connect the multiple positioning holes, facilitating the flow of air and accelerating the solidification of the adhesive layer.

[0014] Preferably, a main groove is formed on the lower end surface of the cover plate, and positioning bumps are fixedly arranged on the bottom of the main groove around the positions of the multiple positioning posts.

[0015] By adopting the above technical solution, the positioning bumps surround the multiple positioning posts. When the positioning posts are inserted into the positioning holes, the positioning posts are limited, so that there is a gap between the positioning posts and the main groove, preventing the surface of the main groove from rubbing against the bottom plate, thereby reducing wear.

[0016] Preferably, a stepped diamond groove is formed on the bottom of the main groove around the multiple positioning bumps.

[0017] By adopting the above technical solution, the diamond groove is formed at the bottom of the main groove, making the bottom of the main groove uneven, thereby increasing the friction of the cover plate and facilitating the installation of the cover plate on the top of the bottom plate by personnel.

[0018] Preferably, lower through holes are formed on the bottom plate at the positions of the multiple studs, and the multiple lower through holes are respectively abutted against the nuts.

[0019] By adopting the above technical solution, the stud penetrates through the lower through hole, and the nut is in threaded connection with the stud, so that the whole bottom of the stud is fixed in the lower through hole.

[0020] Preferably, upper through holes are formed on the cover plate at the positions of the multiple studs, and the multiple upper through holes are respectively abutted against the nuts.

[0021] By adopting the above technical solution, the stud penetrates through the upper through hole, and the nut is in threaded connection with the stud, so that the whole top of the stud is fixed in the upper through hole, and then the bottom plate and the cover plate are integrally connected in cooperation with the lower through hole.

[0022] Preferably, the four diagonals of the side surfaces of the bottom plate and the cover plate are all arranged as arc surfaces.

[0023] By adopting the above technical solution, the outer surfaces of the bottom plate and the cover plate are both arranged as arc surfaces, thereby reducing the contact force between the four diagonals of the bottom plate and the cover plate and the outside, and thus reducing the wear risk.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. The positioning posts are used to drive the adhesive layer to bond with the module, and the stud connection is used to continuously clamp the bottom plate and the cover plate, so that the positioning posts and the module as a whole are fixed, thereby synchronously fixing multiple modules at the same time, improving the positioning efficiency. At the same time, the adhesive layer bonding method has low VOC emissions, is non-toxic and harmless, and improves the environmental protection effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will further describe the present application in detail with reference to the attached Figure 1 - Figure 4 drawings.

[0033] The embodiment of the present application discloses a hydrolysis glue bonding and precision carving positioning tooling.

[0034] Refer to Figure 1 , Figure 2 , Figure 4, A hydrolysis glue bonding and precision carving positioning tooling, including a bottom plate 1. A plurality of positioning holes 3 (the number of positioning holes 3 is at least eight) are provided on the upper end surface of the bottom plate 1. The plurality of positioning holes 3 are distributed in two rows on the upper surface of the bottom plate 1 in pairs, and a fitting module 5 is inserted into each positioning hole 3. The thickness of the module 5 is less than the depth of the positioning hole 3. An air vent groove 4 is provided on the upper end surface of the bottom plate 1 between two adjacent positioning holes 3, and the air vent groove 4 penetrates the bottom plate 1 to connect two adjacent positioning holes 3.

[0035] The module 5 is integrally inserted into the bottom plate 1 from the positioning hole 3, so that the inner wall of the positioning hole 3 laterally fixes the module 5 to form a limit to prevent the module 5 from shifting. After the module 5 is inserted into the positioning hole 3, there is a space reserved on the inner wall of the positioning hole 3 and exposed to the outside, so as to assist in guiding the subsequent insertion of the cover plate 2. At the same time, the air vent groove 4 connects a plurality of positioning holes 3, leaving a through groove between a plurality of modules 5, facilitating air circulation and assisting in air drying for the subsequent gluing operation.

[0036] Refer to Figure 1 、 Figure 2 、 Figure 3 On the top of the bottom plate 1, a cover plate 2 is aligned and connected, and the width of the cover plate 2 is the same as that of the bottom plate 1. Positioning posts 10 are fixedly provided at positions on the lower end surface of the cover plate 2 that are aligned with the plurality of positioning holes 3, and the widths of the plurality of positioning posts 10 are the same as those of the positioning holes 3. A glue layer 12 is fixedly provided at the bottom of each positioning post 10. The glue layer 12 is set as an ultraviolet curable glue. At the same time, positioning bumps 11 are glued and fixedly connected around the plurality of positioning posts 10 on the lower end surface of the cover plate 2. The positioning bumps 11 are made of rubber material and have a certain elasticity. The positioning bumps 11 are in a ring-shaped stepped state to surround and cover the top of the positioning posts 10. A main groove 8 is inwardly provided on the part of the lower end surface of the cover plate 2 outside the plurality of positioning bumps 11, and a diamond-shaped groove 9 is provided at the bottom of the main groove 8 between the plurality of positioning bumps 11. The diamond-shaped groove 9 is in a diamond-shaped stepped state.

[0037] The cover plate 2 is pressed down to drive the positioning posts 10 to descend synchronously, so that the bottom of the positioning posts 10 is inserted into the positioning holes 3. When the positioning posts 10 are pressed down onto the surface of the module 5, the glue layer 12 is driven to bond and fix with the upper end surface of the module 5, forming an integral connection between the cover plate 2 and the module 5. When the positioning posts 10 are inserted downward, the positioning bumps 11 cover the bottom of the positioning posts 10 to form a protrusion, preventing the main groove 8 from contacting the surface of the bottom plate 1 and generating friction when the positioning posts 10 are completely inserted into the positioning holes 3, reducing wear. At the same time, the opening of the diamond-shaped groove 9 makes the bottom of the main groove 8 uneven, thereby increasing friction and facilitating personnel to take.

[0038] Refer to Figure 1 、 Figure 3 、 Figure 4, on the upper end surface of the bottom plate 1, lower through holes 14 are provided at four diagonal positions around multiple positioning holes 3. The lower through holes 14 are funnel-shaped, and the funnel openings of the lower through holes 14 penetrate downward through the bottom of the bottom plate 1 and communicate with the outside. Upper through holes 13 are provided at the positions of the four lower through holes 14 at the bottom of the main groove 8. The upper through holes 13 are funnel-shaped, and the funnel openings of the upper through holes 13 penetrate upward through the top of the cover plate 2 and communicate with the outside. Threads are provided on the inner walls of the four upper through holes 13 and the lower through holes 14. At the same time, the side surfaces of the bottom plate 1 and the cover plate 2 at the four diagonal positions are both provided with arc surfaces 15.

[0039] It should be noted that stud bolts 6 are connected in all four upper through holes 13, and the stud bolts 6 are screwed into the upper through holes 13 from the top downward. The bottom of the stud bolts 6 is screwed out of the lower through holes 14 and thus protrudes from the bottom of the bottom plate 1. Nuts 7 are screwed on the surfaces of the stud bolts 6 at the positions of the funnel openings of the upper through holes 13 and the lower through holes 14.

[0040] The bottom of the stud bolt 6 is turned downward from the funnel opening at the top of the upper through hole 13, and then turned out from the funnel opening at the bottom of the lower through hole 14, so as to integrally connect the bottom plate 1 and the cover plate 2. By rotating the nut 7 located in the lower through hole 14, the nut 7 is threadedly moved upward along the surface of the stud bolt 6, so as to apply a thrust to the bottom plate 1. At the same time, the cover plate 2 is kept stationary by the abutment of the nut 7 at the top of the stud bolt 6. With the rotation of the nut 7, the bottom plate 1 is pushed to make the upper end surface of the module 5 abut and adhere to the adhesive layer 12, and the bottom plate 1 and the cover plate 2 are kept in a clamping state to apply a fixing force to the module 5, so that the module 5 is connected to the positioning post 10.

[0041] The implementation principle of a hydrolysis glue bonding and precision carving positioning tooling in an embodiment of the present application is as follows: When using this device, the operator first inserts the module 5 to be positioned into the positioning holes 3 from top to bottom, and then applies an adhesive layer 12 to the bottom of the positioning posts 10;

[0042] The operator takes the cover plate 2 and aligns the positioning posts 10 downward with the positioning holes 3, and then moves the cover plate 2 downward so that the positioning posts 10 are inserted into the positioning holes 3. As the positioning posts 10 continue to be inserted, the adhesive layer 12 abuts against the surface of the module 5, and an overall bond is formed between the module 5 and the adhesive layer 12 through the adhesive in the adhesive layer 12. After the adhesive layer 12 is bonded to the module 5, the four stud bolts 6 are screwed into the four upper through holes 13, and then the bottoms of the stud bolts 6 are turned out from the lower through holes 14. Then, the nuts 7 are turned out from the bottoms of the stud bolts 6 and partially threadedly connected, and the nuts 7 are rotated to make the nuts 7 threadedly move upward along the surfaces of the stud bolts 6, so that the stud bolts 6 push the entire bottom plate 1 upward, thereby compressing the gap between the adhesive layer 12 and the module 5 during bonding, and discharging the air from the ventilation grooves 4 to the outside. At the same time, when the nuts 7 abut against the inner walls of the funnels of the lower through holes 14, the bottom plate 1 and the cover plate 2 are integrally fixed, and continuous clamping is applied to the adhesion between the adhesive layer 12 and the module 5, facilitating the fixing of the module 5;

[0043] Then, the operator irradiates the adhesive layer 12 with an ultraviolet lamp, so that the adhesive layer 12 is cured, integrally connecting the module 5 and the positioning post 10, removing the nut 7 from the surface of the stud 6, and turning the stud 6 out from between the bottom plate 1 and the cover plate 2, so that the cover plate 2 is separated from the bottom plate 1, and the cover plate 2 drives the module 5 to be withdrawn, thus facilitating the engraving operation of the module 5.

[0044] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
