Description

Technical Field

[0001] This utility model relates to the field of mechanical parts processing technology, and in particular to a high-precision metal mechanical parts processing fixture. Background Technology

[0002] In the processing of metal mechanical parts, it is necessary to fix the parts to prevent them from moving during processing. In order to ensure the positional accuracy of the parts during processing and improve processing efficiency and product quality, a high-precision metal mechanical parts processing fixture is used.

[0003] To address this, patent CN211073272U discloses a machining fixture for mechanical parts, comprising a base, a fixture table, a fixed plate, a first electric telescopic rod, brush bristles, a brush bristle fixing plate, a first support plate, a second electric telescopic rod, a first clamping plate, a rectangular block, a second support plate, a motor, a rotating roller fixing plate, a third electric telescopic rod, a rotating roller, a slide rod, a third support plate, a fourth electric telescopic rod, a second clamping plate, a cavity, and a spring. This utility model is reasonably designed. The brush bristles effectively remove waste material from the fixture table, and the cotton cloth on the rotating roller effectively removes oil stains, ensuring that the fixture is not affected by subsequent uses. Furthermore, the slide rod can be adjusted in size via the inner diameter of the square tube, and the motor output is connected to the rectangular block, allowing the rectangular block to rotate. This enables the machining of multiple surfaces of the square tube at once, making machining more convenient.

[0004] Although the aforementioned machining fixtures for mechanical parts allow for the processing of multiple surfaces of square tubes at once, their lack of support and the inconvenience of feeding and unloading parts make them extremely inconvenient to use. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision metal mechanical parts processing fixture to solve the problem that existing high-precision metal mechanical parts processing fixtures are inconvenient to support.

[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-precision metal mechanical parts processing fixture, including a worktable and a rotating assembly;

[0007] The top of the workbench is fixed with a support structure, which includes a support, a first electric push rod, a guide rod and a placement seat. The support is fixed to the top of the workbench, and the first electric push rod passes through the top of the support. The top of the first electric push rod is fixed with a placement seat, and guide rods pass through the interior of the supports on both sides of the first electric push rod.

[0008] A movable structure is fixed on one side of the top of the workbench;

[0009] A rotating assembly is fixed to the other side of the top of the workbench. A first turntable is fixed to one end of the rotating assembly, and a clamping structure is fixed to one side of the first turntable.

[0010] When using this device, the supporting structure facilitates feeding and unloading, thereby improving the convenience of using this high-precision metal parts processing fixture; the clamping structure facilitates fixing, thereby improving the stability of this high-precision metal parts processing fixture during use; and the movable structure facilitates support, thereby improving the applicability of this high-precision metal parts processing fixture during use.

[0011] Preferably, the guide rod and the support form a sliding structure, with the top end of the guide rod fixedly connected to the bottom end of the placement seat. The placement seat facilitates support for the accessory, and the first electric push rod enables the placement seat to move the accessory up and down. The guide rod enhances the stability of the placement seat during movement.

[0012] Preferably, the rotating assembly includes a housing, a driven gear, a rotating shaft, a first servo motor, and a driving gear. The housing is fixed to the top of the worktable. A driving gear is located on one side of the housing's interior. A driven gear is meshed with one side of the driving gear. A rotating shaft is fixed to one end of the driven gear. The first servo motor is mounted on the outer wall of the housing at one end of the driving gear. When the first servo motor is started, it drives the driving gear to rotate inside the housing. The driving gear, through the driven gear, drives the rotating shaft to rotate.

[0013] Preferably, one end of the rotating shaft extends to the outside of the housing and is fixedly connected to one side of the first turntable, and the output end of the first servo motor extends to the inside of the housing and is fixedly connected to one end of the drive gear. The rotating shaft drives the fixed frame to rotate via the first turntable, and the fixed frame drives the second turntable to rotate inside the moving plate via the accessory, so as to process the various surfaces of the accessory.

[0014] Preferably, the clamping structure includes a fixed frame, a threaded rod, a movable seat, a slide bar, a second servo motor, a clamping plate, and a rubber pad. The fixed frame is fixed to one side of the first turntable. A threaded rod is provided on one side inside the fixed frame. A second servo motor is installed on the outer wall of the fixed frame at one end of the threaded rod. Movable seats are threaded to the outer sides of both ends of the threaded rod. A slide bar passes through one side of the inner side of each movable seat. One side of each movable seat extends to the outside of the fixed frame and is fixed with a clamping plate. A rubber pad is fixed to one side of each clamping plate. By having the threads at both ends of the threaded rod in opposite directions, the movable seats at both ends move in opposite directions. Under the action of the slide bar, the movable seats are prevented from rotating with the threaded rod. The movable seats drive the clamping plate to move, so that the rubber pad is clamped on one side of the accessory.

[0015] Preferably, the threads at both ends of the threaded rod are in opposite directions, one end of the threaded rod extends to the outside of the fixed frame and is fixedly connected to the output end of the second servo motor, the slide rod and the moving seat form a sliding structure, and both ends of the slide rod are fixedly connected to the inner wall of the fixed frame. The rubber pad enhances the friction between the clamping plate and the accessory, thus securing the accessory and preventing displacement during processing.

[0016] Preferably, the movable structure includes a movable plate, a support plate, a second electric push rod, a slide rail, a fixed plate, a second turntable, and a slide block. The support plate is fixed to the top of the worktable, and the second electric push rod passes through the top of the support plate. A movable plate is fixed to one end of the second electric push rod. The second turntable is rotatably connected to one side of the top of the movable plate. A fixed plate is fixed to the bottom of the movable plate. Slide rails are fixed to both sides of the top of the worktable below the fixed plate, and slide blocks are slidably connected to the outer sides of the top of each slide rail. Under the action of the second electric push rod, the movable plate drives the second turntable to move back and forth. The cooperation of the slide blocks and slide rails enhances the stability of the movable plate during movement.

[0017] Preferably, the bottom end of the fixed plate is fixedly connected to the top end of the slide, and an anti-slip pad is fixed to one side of the second turntable. The moving plate drives the anti-slip pad to abut against one end of the accessory through the second turntable. Under the action of the anti-slip pad, the friction between the accessory and the second turntable is enhanced, so as to support the accessory.

[0018] The present invention provides a high-precision metal machining fixture, the advantages of which are:

[0019] With the support structure, the parts are easily supported by the placement seat. The first electric push rod enables the placement seat to move the parts up and down. The guide rod enhances the stability of the placement seat during movement, realizing the function of easy feeding and unloading of materials. This improves the convenience of using the high-precision metal mechanical parts processing fixture.

[0020] By incorporating a clamping structure, the opposite threads at both ends of the threaded rod cause the moving seats at both ends to move in opposite directions. Under the action of the sliding rod, the moving seats are prevented from rotating along with the threaded rod. The moving seats drive the clamping plate to move, causing the rubber pad to clamp onto one side of the part. The rubber pad enhances the friction between the clamping plate and the part, thus fixing the part in place and preventing displacement during processing. This device facilitates easy fixing and improves the stability of the high-precision metal machining fixture during use.

[0021] By incorporating a movable structure, the second electric push rod enables the movable plate to move the second turntable back and forth. The cooperation of the slide block and slide rail enhances the stability of the movable plate during movement. The movable plate, through the second turntable, causes an anti-slip pad to contact one end of the component. The anti-slip pad enhances the friction between the component and the second turntable, thus supporting the component. This design facilitates support and improves the applicability of the high-precision metal machining fixture. Attached Figure Description

An anti-slip pad is fixed to one side of the second turntable 606.

[0033] Reference Figure 2 and Figure 6 As shown, the second electric push rod 603 is activated, which drives the moving plate 601 to move. The moving plate 601 drives the slide block 607 to move outside the slide rail 604 through the fixed plate 605. With the cooperation of the slide block 607 and the slide rail 604, the stability of the moving plate 601 during movement is enhanced. At the same time, the moving plate 601 drives the anti-slip pad to abut against one end of the accessory through the second turntable 606. Under the action of the anti-slip pad, the friction between the accessory and the second turntable 606 is enhanced, so as to support the accessory.

[0034] A rotating assembly 3 is fixed to the other side of the top of the workbench 1. A first turntable 4 is fixed to one end of the rotating assembly 3.

Movable seats 503 are threaded to the outer sides of both ends of the threaded rod 502. A slide rod 504 passes through one side inside the movable seat 503. One side of the movable seat 503 extends to the outside of the fixed frame 501 and is fixed with a clamping plate 506. A rubber pad 507 is fixed to one side of the clamping plate 506. The threads at both ends of the threaded rod 502 are in opposite directions. Extending to the outside of the fixed frame 501 and fixedly connected to the output end of the second servo motor 505, the slide rod 504 and the moving seat 503 form a sliding structure. Both ends of the slide rod 504 are fixedly connected to the inner wall of the fixed frame 501. The rotating component 3 includes a housing 301, a driven gear 302, a rotating shaft 303, a first servo motor 304 and a driving gear 305. The housing 301 is fixed to the top of the worktable 1.

The output end of the first servo motor 304 extends to the inside of the housing 301 and is fixedly connected to one end of the driving gear 305.

[0035] Reference Figure 3 and Figure 4As shown, the second servo motor 505 is activated, driving the threaded rod 502 to rotate inside the fixed frame 501. Because the threads at both ends of the threaded rod 502 are in opposite directions, the moving seats 503 at both ends can move in opposite directions. Simultaneously, the moving seats 503 move outside the slide rod 504. Under the action of the slide rod 504, the moving seats 503 are prevented from rotating with the threaded rod 502. The moving seats 503 drive the clamping plate 506 to move, causing the rubber pad 507 to clamp onto one side of the accessory. Under the action of the rubber pad 507, the clamping effect is enhanced. The friction between the clamping plate 506 and the accessory is reduced to fix the accessory and prevent it from shifting during processing. The first servo motor 304 is started, which drives the drive gear 305 to rotate inside the housing 301. The drive gear 305 drives the rotating shaft 303 to rotate through the driven gear 302. The rotating shaft 303 drives the fixed frame 501 to rotate through the first turntable 4. The fixed frame 501 drives the second turntable 606 to rotate inside the moving plate 601 through the accessory, so as to process the various surfaces of the accessory.

[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
