Description

Technical Field

[0001] This utility model relates to the field of metal fixture technology, specifically a metal fixture that is easy to assemble and disassemble. Background Technology

[0002] When manufacturing small metal parts, especially aluminum and copper parts, such as valve bodies made of aluminum and copper castings used in gas pipelines, and other small aluminum and copper castings, a completely manual processing method is adopted, and the workpiece needs to be fixed and limited by a fixture during processing.

[0003] Traditional metal fixtures mainly consist of a metal substrate, positioning components, clamping mechanisms, guiding parts, and functional accessories. In use, first clean the fixture and workpiece surfaces to remove impurities, and adjust the positions of the positioning components and clamping mechanisms according to the workpiece dimensions. Next, place the workpiece into the fixture's positioning area and secure it firmly using the clamping mechanism. Check that the workpiece fits snugly against the positioning surface and is not loose. Then, perform the operation in conjunction with processing equipment (such as a milling machine or drilling machine), observing the fixture's stability during the process. After the operation is complete, loosen the clamping mechanism, remove the workpiece, clean any remaining debris from inside the fixture, check the wear of the positioning components and clamping mechanism, and perform maintenance to ensure accuracy for the next use.

[0004] In actual production scenarios, dimensional errors and assembly gaps in positioning components during the processing of existing metal jigs can easily lead to insufficient reference accuracy of the jigs themselves, making it difficult to meet the requirements of high-precision processing. Furthermore, the clamping mechanism has significant defects, relying on manually adjusting bolts or simple clips for fixation. This is not only cumbersome and time-consuming, but also unable to quickly respond to the efficient clamping requirements of mass production. These jigs often fail to provide uniform and stable tightness and restraint on all four sides of the workpiece, only fixing localized areas. During the pressing and cooling process after dispensing, the workpiece is affected by external forces or temperature changes, and the corners that are not effectively restrained are prone to lateral displacement, resulting in dispensing position deviation and poor pressing adhesion. Utility Model Content

[0005] The purpose of this invention is to provide a metal fixture that is easy to assemble and disassemble, in order to solve the problems in actual production scenarios. Existing metal fixtures often suffer from insufficient reference accuracy due to dimensional errors and gaps in the assembly of positioning components, making it difficult to meet the requirements of high-precision machining. Furthermore, their clamping mechanisms have significant defects, relying on manually adjusting bolts or simple clips for fixation. This is not only cumbersome and time-consuming, but also unable to quickly respond to the efficient clamping requirements of mass production. These fixtures often fail to provide uniform and stable tightness and restraint on all four sides of the workpiece, only fixing localized areas. During the pressing and cooling process after dispensing, the workpiece is affected by external forces or temperature changes, and the corners that are not effectively restrained are prone to lateral displacement, leading to dispensing position deviation and poor pressing adhesion.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A metal fixture that is easy to assemble and disassemble includes a base plate on which a positioning plate is fixedly mounted.

[0008] The positioning unit includes a positioning post 1 fixedly mounted on the positioning plate, and each positioning post 1 is arranged parallel to each other, with equal distance between two adjacent positioning posts 1. A positioning post 2 is fixedly mounted on the positioning plate, and a fixing plate is fixedly mounted on the positioning plate, with each positioning post 1 penetrating through the fixing plate. The fixing plate has a slot for fixing materials. The positioning unit is used to position and fix the materials to be processed.

[0009] The pressing unit includes a pressing plate slidably disposed on the fixed plate, a processing plate fixedly disposed on the pressing plate, and the pressing plate and the fixed plate being arranged parallel to each other. The pressing unit is used to press materials placed in the slots of the fixed plate.

[0010] Preferably, the positioning plate, the fixing plate, and the pressure plate are of equal length and the same width.

[0011] Preferably, each of the positioning posts 2 is evenly distributed at each corner of the positioning plate, and the length of each positioning post 2 is not less than the sum of the thicknesses of the positioning plate, the fixing plate and the pressure plate. A clamping plate 2 is fixedly provided on the top of each positioning post 2, and a plurality of positioning holes 2 matching the positioning posts 2 are provided on the fixing plate.

[0012] Preferably, a dispensing column is fixedly provided on the positioning plate, and a cap is fitted on the outside of the dispensing column. The top of the cap is arc-shaped. A corresponding dispensing hole is provided on the fixing plate, and a dispensing opening is fixedly provided on the top of the dispensing column.

[0013] Preferably, the fixing plate has a positioning hole that matches the positioning post, and a retaining ring is fixedly provided on the inner wall of the positioning hole. The diameter of the positioning hole matches the positioning post, and a retaining plate is fixedly provided on the top of the positioning post.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] This invention uses a base plate at the bottom of the positioning plate to position and fix the entire device. A fixing plate and a pressure plate on the positioning plate allow for material placement. First, the pressure plate and fixing plate are separated. Then, the material to be processed is placed in the slot on the fixing plate and secured by spring clips. A reinforcing rod on the processing plate fixes the processing plate and connecting plate, ensuring the stability of the device during use and preventing lateral thrust on the material during pressing, which could lead to dispensing failure. Furthermore, during the pressing process, the pressure plate presses down on the airbag on the fixing plate. The airbag releases its internal gas through the telescopic rod of the device via a pipeline, thus moving the clamping plate and improving the stability of the material clamping. Both the telescopic rod and the pipeline body are made of highly elastic rubber, ensuring good elasticity and preventing damage to the material during clamping. Attached Figure Description

[0027] The positioning unit includes positioning posts 21 fixedly mounted on the positioning plate 2, with each positioning post 21 arranged parallel to each other and the distance between two adjacent positioning posts 21 being equal. Positioning posts 24 are fixedly mounted on the positioning plate 2, and a fixing plate 3 is fixedly mounted on the positioning plate 2, with each positioning post 21 penetrating through the fixing plate 3.

The pressing unit is used to press the material placed in the slot of the fixed plate 3.

[0029] Reference Figures 1-4 The positioning plate 2, the fixing plate 3, and the pressure plate 4 are of equal length and width. By setting the size relationship between the positioning plate 2, the fixing plate 3, and the pressure plate 4, the stability of the device during processing is ensured.

[0030] Reference Figures 1-3 Each positioning post 24 is evenly distributed at each corner of the positioning plate 2, and the length of the positioning post 24 is not less than the sum of the thicknesses of the positioning plate 2, the fixing plate 3, and the pressure plate 4. A clamping plate 241 is fixedly installed on the top of the positioning post 24. The fixing plate 3 has multiple positioning holes 34 that match the positioning post 24. The positioning posts 24 installed on the positioning plate 2 facilitate the stability of the device after it is fixed.

[0031] Reference Figures 2-4A dispensing column 22 is fixedly installed on the positioning plate 2, and a cap 23 is fitted on the outside of the dispensing column 22. The top of the cap 23 is arc-shaped. A corresponding dispensing hole 32 is opened on the fixing plate 3. A dispensing nozzle 221 is fixedly installed on the top of the dispensing column 22. By using the dispensing column 22 installed on the positioning plate 2, the staff can apply glue to the material after fixing it.

[0032] Reference Figures 2-4 The fixed plate 3 has a positioning hole 311 that matches the positioning post 21, and a retaining ring 312 is fixedly installed on the inner wall of the positioning hole 311. The diameter of the positioning hole 311 matches the positioning post 21. A retaining plate 211 is fixedly installed on the top of the positioning post 21.

[0033] Reference Figures 1-4 An airbag 33 is fixedly installed on the fixed plate 3. A telescopic rod 351 is slidably installed at the slot of the fixed plate 3, and a clamping plate 35 is fixedly installed on one end of the telescopic rod 351. The other end of the telescopic rod 351 is connected to the airbag 33 through a pipe. The airbag 33 installed on the fixed plate 3 can compress the airbag 33 when the pressure plate 4 is pressed down. At this time, the gas in the airbag 33 can be transported to the telescopic rod 351 of the device through the pipe, and the clamping plate 35 can be used to clamp and fix the material.

[0035] Reference Figures 2-4 The positioning holes on the processing plate 41 are inclined at the edges, and the diameter of each reinforcing rod 42 matches the positioning holes. By setting the positioning holes to be inclined, the assembly of the reinforcing rods 42 is improved.

[0036] Specifically, this solution involves: positioning and fixing the entire device by setting a base plate 1 at the bottom of the positioning plate 2; separating the pressure plate 4 from the fixed plate 3 when placing materials by setting a fixing plate 3 and a pressure plate 4 on the positioning plate 2; placing the material to be processed at the slot on the fixed plate 3; and assembling the product by fixing it with a spring 45. The reinforcing rod 42 on the processing plate 41 can fix the position of the processing plate 41 and the connecting plate 43, ensuring the stability of the device during use and avoiding lateral pushing force on the material during pressing, which could lead to dispensing failure. During the pressing process, the pressure plate 4 can press the airbag 33 on the fixed plate 3. At this time, the airbag 33 releases the gas inside through the telescopic rod 351 of the device in the pipeline, thereby pushing the clamping plate 35 to move, improving the stability of the device in clamping the material. Furthermore, the telescopic rod 351 and the pipeline body are both made of highly elastic rubber material to ensure good elasticity and avoid damage to the material during clamping.
