Description

Technical Field

[0001] This utility model relates to the field of positioning and processing technology, and in particular to a positioning base for multi-station composite processing of modular box-type parts. Background Technology

[0002] A positioning base is a basic positioning device used in industrial production processes such as machining, assembly, and testing. It provides precise positioning and stable support for workpieces or fixtures and is one of the key components to ensure machining accuracy and production efficiency.

[0003] In the traditional machining process of box-type parts, the positioning base used has certain limitations. In the existing positioning base, the position of the positioning hole is mostly fixed and cannot be adjusted. This means that when dealing with box-type parts of different sizes and different machining requirements, it is often necessary to replace the entire positioning base to install the appropriate fixture, thereby reducing the machining speed. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the positions of the positioning holes in existing positioning bases are mostly fixed, and to propose a modular box-type part multi-station composite processing positioning base.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A modular box-type part multi-station composite machining positioning base includes a base, a cover plate installed on the top of the base, a locking block and a locking groove installed on one side of the base by screws, a number of insertion holes provided inside the base, a machining table inserted into the number of insertion holes, and an adjustment component that can adjust the position of the insertion holes inside the base.

[0007] The adjustment assembly includes symmetrical through slots on the cover plate. Several first guide rails are fixedly installed on the bottom of the inner wall of the base. A moving block is slidably connected between two first guide rails. Positive and negative threaded rods are rotatably connected inside the two moving blocks. A fixing component capable of limiting the position of the processing table is installed inside the insertion hole. A rotating component capable of adjusting the spacing between the insertion holes is installed inside the base. A clamping assembly capable of fixing box-type parts is also installed on the processing table.

[0008] As a further description of the above technical solution:

[0009] The fixing component includes symmetrically formed grooves inside the insertion hole, a clamping block is inserted into the inside of the groove, the top of the clamping block is set as a downward inclined surface, and a first spring is fixedly installed between the clamping block and the groove.

[0010] As a further description of the above technical solution:

[0011] The rotating component includes a worm gear and a worm wheel rotatably mounted on the bottom side of the inner wall of the base. A turntable is mounted on the shaft of the worm wheel by screws. Two arc-shaped grooves are formed on the turntable. A second guide rail is symmetrically mounted on the bottom end of the inner wall of the base. A movable frame is slidably connected to the top end of the second guide rail. A cylinder is fixedly mounted on one side of the top end of the movable frame.

[0012] As a further description of the above technical solution:

[0013] The worm gear meshes with the worm wheel, the moving block is fixedly installed on the moving frame, the cylinder is located in the arc groove, and the insertion hole is threaded at both ends of the positive and negative threaded rod, with the insertion hole located in the through groove.

[0014] As a further description of the above technical solution:

[0015] The clamping assembly includes vertical plates symmetrically mounted on the top of the processing table. The vertical plates are internally threaded with threaded rods. One end of the threaded rod is rotatably connected to a stop plate, and both ends of the stop plate are inserted with extension plates.

[0016] As a further description of the above technical solution:

[0017] A second spring is fixedly installed between the end of the abutment inserted into the extension plate and the abutment, and a rod with a diameter smaller than the insertion hole is installed at the bottom of the processing table.

[0018] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0019] By setting adjustment components, the position of the insertion holes can be flexibly adjusted. The meshing of the worm and worm wheel, as well as the setting of the positive and negative threaded rods, makes the adjustment of the insertion hole spacing simple and convenient, enabling flexible adjustment of the insertion hole position. This allows for adaptation to the processing needs of box-type parts of different sizes and shapes without replacing the entire positioning base, greatly improving the versatility and flexibility of the positioning base and enabling rapid response to multi-variety, small-batch production tasks. The cooperation between the fixing components and the insertion holes can reliably limit and fix the processing table, ensuring the stability of box-type parts during processing, thereby effectively guaranteeing processing accuracy and reducing processing errors caused by part displacement. The design of the clamping components can meet the fixing requirements of different types of box-type parts, further broadening the application range of this positioning base and enabling it to play an excellent positioning and clamping role in the processing of various box-type parts.

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] like Figure 1 - Figure 7As shown, the present invention provides a modular box-type part multi-station composite processing positioning base, including a base 10, a cover plate 11 installed on the top of the base 10, and the base 10 and the cover plate 11 are fixed together by screws. A locking block 12 and a locking groove 13 are installed on one side of the base 10 by screws. When several bases 10 need to be spliced ​​together, the locking block 12 and the locking groove 13 are respectively installed on both sides of the base 10 by screws, such as... Figure 1 As shown, several bases 10 are then inserted together to complete the splicing. By adjusting the position of the insertion hole 14 on each base 10, multiple processing tables 15 can be installed, thereby realizing multi-station processing of box-type parts. The base 10 has several insertion holes 14 inside, and processing tables 15 are inserted into several insertion holes 14. The base 10 is also equipped with an adjustment component 20 that can adjust the position of the insertion holes 14.

[0033] Adjustment component 20 includes symmetrically formed through slots 21 on cover plate 11, allowing insertion hole 14 to move. Several first guide rails 22 are fixedly mounted on the bottom of the inner wall of base 10. A moving block 23 is slidably connected between two first guide rails 22, maintaining stability during movement via the two first guide rails 22. Positive and negative threaded rods 24 are rotatably connected inside the two moving blocks 23. Figure 1 As shown, two square slots are provided on one side of the base 10. The positive and negative threaded rods 24 are located in the square slots. The square slots ensure that the positive and negative threaded rods 24 are not blocked when they move with the moving block 23. The socket 14 is equipped with a fixing component 25 that can limit the position of the processing table 15. The base 10 is equipped with a rotating component 26 that can adjust the spacing of the socket 14. The processing table 15 is also equipped with a clamping assembly 30 that can fix box-type parts.

[0034] like Figure 5 As shown, the fixing component 25 includes grooves 251 symmetrically opened inside the insertion hole 14. Clamping blocks 252 are inserted into the grooves 251. One side of each clamping block 252 is an arc-shaped opening, and the top of each clamping block 252 is a downwardly inclined slope. A first spring 253 is fixedly installed between the clamping blocks 252 and the grooves 251. When the insertion rod at the bottom of the processing table 15 is inserted into the insertion hole 14, the insertion rod will first contact the inclined slope at the top of the clamping block 252. The descending insertion rod gradually squeezes the clamping blocks 252 on both sides, causing the clamping blocks 252 on both sides to move towards the grooves 251. The reaction force of the first spring 253 causes the clamping blocks 252 on both sides to clamp and fix the insertion rod through the arc-shaped opening, thereby completing the limitation of the processing table 15.

[0035] like Figure 4 - Figure 6As shown, the rotating component 26 includes a worm gear 261 and a worm wheel 262 rotatably mounted on the bottom side of the inner wall of the base 10. One end of the worm gear 261 extends to the outside of the base 10 and is flush with the outer wall of the base 10. A turntable 263 is mounted on the shaft of the worm wheel 262 by screws. When the worm wheel 262 starts to rotate, it will also drive the turntable 263 to start to rotate. Two arc-shaped grooves 264 are opened on the turntable 263. A second guide rail 265 is symmetrically mounted on the bottom end of the inner wall of the base 10. A movable frame 266 is slidably connected to the top end of the second guide rail 265. The movable frame 266 can move through the second guide rail 265. A cylinder 267 is fixedly mounted on one side of the top end of the movable frame 266.

[0036] In more detail, the worm 261 meshes with the worm wheel 262. Rotating the worm 261 causes the worm wheel 262 to rotate through the meshing. The moving block 23 is fixedly installed on the moving frame 266. The cylinder 267 is located in the arc groove 264. When the turntable 263 rotates, the arc groove 264 pushes the cylinder 267, causing the cylinder 267 to move the moving frame 266. The moving frame 266 then moves the moving block 23, thereby allowing the insertion hole 14 to move to adapt to different sizes of processing tables 15. The insertion hole 14 is threaded at both ends of the positive and negative threaded rods 24. By rotating the positive and negative threaded rods 24 in both directions, the insertion hole 14 can move to the opposite or opposite sides, and the insertion hole 14 is located in the through groove 21.

[0037] When it is necessary to adjust the distance between the two sockets 14, the forward and reverse threaded rods 24 are rotated in both directions to allow the sockets 14 to move in opposite directions within the through slots 21. When it is necessary to adjust the spacing between the two sets of sockets 14, the worm gear 261 is rotated, and the worm wheel 262 is engaged to drive the turntable 263 to start rotating. The arc-shaped groove 264 on the turntable 263 allows the cylinder 267 to be pushed when the turntable 263 rotates, which in turn drives the moving frame 266 to move. The moving frame 266 then drives the moving block 23 to move, thereby allowing the sockets 14 to move to adapt to different sizes of processing tables 15.

[0038] like Figure 7 As shown, the clamping assembly 30 includes vertical plates 31 symmetrically mounted on the top of the processing table 15. A threaded rod 32 is threadedly connected to the inside of the vertical plate 31. One end of the threaded rod 32 is rotatably connected to a stop plate 33. The stop plate 33 is slidably mounted on the top of the processing table 15. The stop plate 33 can be moved by rotating the threaded rod 32. Extension plates 34 are inserted into both ends of the stop plate 33. The four sides of the box-shaped part can be clamped and fixed by the extension plates 34 and the stop plate 33.

[0039] In more detail, a second spring is fixedly installed between the end of the abutment plate 33 inserted into the extension plate 34 and the abutment plate 33. When the extension plate 34 extends, the reaction force of the second spring allows the extension plate 34 to clamp both ends of the box-shaped part. A plug rod with a diameter smaller than the insertion hole 14 is installed at the bottom of the processing table 15. In use, the processing table 15 is installed on the top of the cover plate 11, so that the plug rod at the bottom of the processing table 15 can be inserted into the insertion hole 14. Then, the box-shaped part is placed in the middle of the processing table 15, such as... Figure 7 As shown, by rotating the threaded rods 32 on both sides, the abutment plate 33 causes the extension plate 34 to move toward the box-shaped part. The abutment plate 33 presses against both sides of the box-shaped part, and the extension plate 34 and the reaction force of the second spring enable the extension plate 34 to clamp and fix the other two sides of the box-shaped part.

[0040] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
