Description

Technical Field

[0001] This application relates to the field of aluminum alloy processing, and more specifically, to a fixture for aluminum alloy processing. Background Technology

[0002] In the production process of aluminum alloy castings, it is usually necessary to fix the aluminum alloy castings in order to facilitate drilling, milling and other processing. To facilitate this, workers usually use aluminum alloy processing fixtures to clamp and fix the aluminum alloy castings.

[0003] In modern aluminum alloy machining fixtures, the clamping head and the main structure are usually fixedly connected, such as by welding or bolting. When it is necessary to process profiles, irregular parts or thin-walled components of different sizes, changing the clamping head of the corresponding profile often requires disassembling multiple fastening parts, and even requires disassembling one by one with tools such as wrenches and screwdrivers, which affects the processing efficiency of aluminum alloy castings. Utility Model Content

[0004] The summary section of this application is intended to provide a brief overview of the concepts, which will be described in detail in the detailed description section below. This summary section is not intended to identify key or essential features of the claimed technical solutions, nor is it intended to limit the scope of the claimed technical solutions.

[0005] The purpose of this application is to address the shortcomings of the prior art by providing a fixture for aluminum alloy processing. In the prior art, the clamping head and the main structure of the fixture are usually fixedly connected, such as by welding or bolting. When it is necessary to process profiles, irregular parts or thin-walled components of different sizes, changing the clamping head of the corresponding profile often requires disassembling multiple fastening components, and even requires disassembling one by one with tools such as wrenches and screwdrivers. This affects the processing efficiency of aluminum alloy castings.

[0006] To achieve the above objectives, this application provides the following technical solution: A fixture for machining aluminum alloys includes: a base, a fixed mounting platform fixedly disposed on one side of the base, and displacement mechanisms disposed on both sides and above the base. The displacement mechanisms include movable mounting platforms, and quick-change mechanisms are disposed in the middle and above the movable and fixed mounting platforms. The quick-change mechanisms include a turntable, which is disposed above the movable and fixed mounting platforms. Disassembly and assembly components are disposed around the four periphery of the turntable. The disassembly and assembly components include multiple mounting brackets, and limit components are disposed at the back ends of the multiple mounting brackets and in the middle of the movable and fixed mounting platforms.

[0007] Furthermore, the assembly / disassembly assembly includes a mounting bracket, which is distributed around the periphery of the turntable. A screw groove is provided above the mounting bracket and at the corresponding position on the turntable, and a bolt rod is screwed into the middle of the screw groove. A fastening clamp is fixed at the front end of the mounting bracket.

[0008] Furthermore, the mounting bracket utilizes screw slots, bolt rods, and a turntable to form a detachable connection.

[0009] Furthermore, the limiting component includes a reserved groove, which is located in the middle of the movable mounting platform and the fixed mounting platform. A fixed hollow plate is fixedly provided on one side of the horizontal groove of the reserved groove, and a return spring is installed on one side of the fixed hollow plate. The end of the return spring is connected to a limiting guide block, and the end of the limiting guide block is connected to a pull cable. A first guide wheel frame is installed at the end of the horizontal groove of the reserved groove, and a second guide wheel frame is installed at the end of the vertical groove of the reserved groove. A pull buckle is fixed at the end of the pull cable, and limiting slots are provided at the rear ends of the plurality of mounting brackets.

[0010] Furthermore, the opening size of the limiting slot matches the size of its limiting guide block, and the limiting guide block is guided and connected to the transverse groove portion of the reserved slot.

[0011] Furthermore, the displacement mechanism includes a side mounting frame, which is fixed to one side of the base. A rotating rod is installed in the middle of the side mounting frame, and first bevel gears are fixed on both sides of the middle of the rotating rod. A second bevel gear meshes with one side of the two first bevel gears, and a transmission screw is fixed in the middle of the two second bevel gears. A screw sleeve is screwed around one side of the two transmission screws, and a guide frame is fixed around the two screw sleeves. A movable mounting platform is fixed at the end of the two guide frames, and guide rails are fixed on both sides above the base.

[0012] Furthermore, the guide rails on both sides of the fixed mounting platform are horizontally guided to their corresponding guide rails.

[0013] The beneficial effects of this application are as follows: Workers can pre-select appropriate fastening clamps based on the shape of the aluminum alloy profile to be processed. Then, they sequentially pull the latches on one side of the fixed mounting platform and the movable mounting platform. Taking the movable mounting platform as an example: when the latches are pulled, the cable will follow the guides of the first and second guide wheel frames, causing the end-connected limit guide block to move in accordance with the transverse groove guide of the pre-reserved groove. During this process, the limit guide block will compress the return spring at its end. At this time, the limit guide block can disengage from the limit slot at the rear end of the corresponding mounting bracket. Afterwards, the worker can rotate the unrestricted turntable to... After adjusting the front end of the mounting bracket with a suitable fastening clamp to the working surface, release the pull buckle. Under the reset action of the return spring, the limit guide block will be aligned and inserted into the limit slot at the rear end of the new mounting bracket, thereby fixing the position of the fastening clamp of the corresponding profile at the front end of the new mounting bracket. At this time, the matching aluminum alloy profile can be clamped and fixed by the displacement mechanism. It is worth mentioning that there are four sets of mounting positions around the top of the turntable. When it is necessary to install a fastening clamp other than the four sets, the operator can use the screw slot and bolt rod to perform the corresponding replacement operation.

[0014] After the mounting brackets and clamps on the opposite sides of the fixed mounting platform and the movable mounting platform are adjusted, the operator can manually rotate the rotating rod, causing the first bevel gears on both sides of the middle of the rotating rod to rotate. The second bevel gears, which mesh with the two first bevel gears respectively, will rotate synchronously and drive their respective fixed transmission screws to rotate. At this time, the screw sleeves that cooperate with the two transmission screws will carry the guide frames and the same movable mounting platform connected to the end of the guide frames to move along the guide rail. Through this series of transmissions, the distance between the clamps on the working surfaces of the movable mounting platform and the fixed mounting platform can be indirectly adjusted, ultimately achieving the clamping of the aluminum alloy profile.

[0022] The present application will now be described in detail with reference to the accompanying drawings and embodiments.

[0023] Reference Figures 1-4As shown, this utility model provides a fixture for aluminum alloy processing, including: a base 1, a fixed mounting platform 2 fixedly mounted on one side of the base 1, and displacement mechanisms 3 arranged on both sides and above the base 1. The displacement mechanism 3 includes a movable mounting platform 39, and a quick switching mechanism 4 is arranged in the middle and above the movable mounting platform 39 and the fixed mounting platform 2. The displacement mechanism 3 includes a side mounting frame 31, which is fixedly mounted on one side of the base 1. A rotating rod 32 is installed in the middle of the side mounting frame 31, and first bevel gears 33 are fixedly mounted on both sides of the middle of the rotating rod 32. A second bevel gear 34 meshes with one side of the two first bevel gears 33, and a transmission screw 35 is fixedly mounted in the middle of the two second bevel gears 34. A screw sleeve 36 is screwed around one side of the two transmission screws 35, and a guide frame 37 is fixed around the two screw sleeves 36. A movable mounting platform 39 is fixed at the end of the two guide frames 37. Guide rails 38 are fixed on both sides of the upper part of the fixed mounting platform 2. The guide frames 37 on both sides of the fixed mounting platform 2 are horizontally connected to the guide rails 38. After the mounting brackets 421 and fastening clamps 424 on the opposite side of the fixed mounting platform 2 and the movable mounting platform 39 are adjusted, the operator can manually rotate the rotating rod 32, so that the first bevel gears 33 on both sides of the middle part of the rotating rod 32 rotate accordingly. The second bevel gears 34 that mesh with the two first bevel gears 33 will rotate synchronously and drive the transmission screws 35 fixed on them to rotate. At this time, the screw sleeves 36 that cooperate with the two transmission screws 35 will carry the guide frame 37 connected to them and the same movable mounting platform 39 connected to the end of the guide frame 37 to move along the guide rails 38. Through this series of transmissions, the distance between the fastening clamps 424 on the working surface of the movable mounting platform 39 and the fixed mounting platform 2 can be indirectly adjusted, and finally the aluminum alloy profile can be clamped.

[0024] The quick-change mechanism 4 includes a turntable 41, which is mounted above the movable mounting platform 39 and the fixed mounting platform 2. Disassembly and assembly components 42 are provided around the four periphery of the turntable 41. Each component includes a mounting bracket 421, which is distributed around the turntable 41. Screw grooves 422 are provided above the mounting brackets 421 and at corresponding locations on the turntable 41. Bolt rods 423 are screwed into the center of each screw groove 422. A fastening clamp 424 is fixed to the front end of each mounting bracket 421. The mounting brackets 421 are detachably connected via the screw grooves 422, bolt rods 423, and the turntable 41. Limiting components 43 are provided at the back ends of the multiple mounting brackets 421 and in the middle of the movable mounting platform 39 and the fixed mounting platform 2. 3 includes a reserved groove 431, which is located in the middle of the movable mounting platform 39 and the fixed mounting platform 2. A fixed hollow plate 432 is fixedly installed on one side of the horizontal groove of the reserved groove 431, and a return spring 433 is installed on one side of the fixed hollow plate 432. The end of the return spring 433 is connected to a limit guide block 434, and the end of the limit guide block 434 is connected to a pull cable 435. A first guide wheel frame 436 is installed at the end of the horizontal groove of the reserved groove 431, and a second guide wheel frame 437 is installed at the end of the vertical groove of the reserved groove 431. A pull buckle 438 is fixed at the end of the pull cable 435. Limit slots 439 are opened at the rear ends of multiple mounting brackets 421. The opening size of the limit slots 439 is consistent with that of the limit guide block 434. The dimensions of the 34 profiles are matched, and the limiting guide block 434 is guided and connected to the transverse groove of the reserved groove 431. The operator can pre-select a suitable fastening clamp 424 according to the shape of the aluminum alloy profile to be processed. Then, the pull buckle 438 on one side of the fixed mounting platform 2 and the movable mounting platform 39 is pulled in sequence. Taking the movable mounting platform 39 as an example: when the pull buckle 438 is pulled, the cable 435 will follow the guidance of the first guide wheel frame 436 and the second guide wheel frame 437, driving the limiting guide block 434 connected at the end to move in coordination with the transverse groove of the reserved groove 431. During this process, the limiting guide block 434 will compress the return spring 433 at the end. At this time, the limiting guide block 434 can disengage from the limiting slot 439 at the rear end of the corresponding mounting bracket 421. The operator can then rotate the unrestricted turntable 41 to adjust the front end of the mounting bracket 421 with the appropriate fastening clamp 424 to the working surface. After adjustment, the pull buckle 438 is released. Under the reset action of the return spring 433, the limit guide block 434 will be aligned and inserted into the limit slot 439 at the rear end of the new mounting bracket 421, thereby fixing the position of the fastening clamp 424 of the corresponding profile at the front end of the new mounting bracket 421. At this time, the clamping and fixing of the matching aluminum alloy profile can be achieved through the displacement mechanism 3. It is worth mentioning that there are four sets of mounting positions around the top of the turntable 41. When it is necessary to install a fastening clamp 424 other than the four sets, the operator can use the screw groove 422 and the bolt rod 423 to perform the corresponding replacement operation.

[0025] Working principle: When using this aluminum alloy processing fixture, the operator can pre-select a suitable fastening chuck 424 according to the shape of the aluminum alloy profile to be processed. Then, the operator sequentially pulls the latches 438 on one side of the fixed mounting platform 2 and the movable mounting platform 39. Taking the movable mounting platform 39 as an example: when the latches 438 are pulled, the cable 435 will follow the guidance of the first guide wheel frame 436 and the second guide wheel frame 437, driving the end-connected limiting guide block 434 to move in accordance with the transverse groove guide of the reserved groove 431. During this process, the limiting guide block 434 will compress the end-end return spring 433. At this time, the limiting guide block 434 can disengage from the limiting slot 439 at the rear end of the corresponding mounting bracket 421. Afterwards, the operator can rotate... The rotating turntable 41, which moves without resistance, adjusts the front end of the mounting bracket 421 with a suitable fastening clamp 424 to the working surface. After adjustment, the pull buckle 438 is released. Under the reset action of the return spring 433, the limit guide block 434 will be inserted into the limit slot 439 at the rear end of the new mounting bracket 421, thereby fixing the position of the fastening clamp 424 of the corresponding profile at the front end of the new mounting bracket 421. At this time, the clamping and fixing of the matching aluminum alloy profile can be achieved by the displacement mechanism 3. It is worth mentioning that there are four sets of mounting positions on the upper periphery of the turntable 41. When it is necessary to install a fastening clamp 424 other than the four sets, the operator can use the screw groove 422 and the bolt rod 423 to perform the corresponding replacement operation.
