Description

Technical Field

[0001] This utility model relates to the field of fixtures, and in particular to a fixture for machining electromechanical equipment. Background Technology

[0002] Fixtures for machining electromechanical equipment are mainly used to ensure the stable positioning of workpieces during the machining process of electromechanical equipment parts.

[0003] Utility model CN221735495U discloses a fixture for machining electromechanical equipment. The key technical points are: it includes a base connected to a moving mechanism and a clamping adjustment mechanism. The clamping adjustment mechanism includes a pneumatic cylinder, a fixed plate, and a first T-shaped slider. The first T-shaped slider has a stepped hole connected to a limiting post. The limiting post is fitted with a spring and connected to a clamping plate via a C-shaped telescopic plate. The fixed plate has a limiting groove. This utility model uses a pneumatic cylinder to move the fixed plate and clamping plate, achieving clamping of electromechanical equipment components. The limiting post enters the limiting groove, fixing the first T-shaped slider. Simultaneously, the spring is compressed. The left and right positions of the electromechanical equipment components can be adjusted by controlling the extension and retraction of the pneumatic cylinder. When the pneumatic cylinder retracts, the limiting post disengages from the limiting groove. Then, a rotating motor drives a lead screw to rotate, thereby moving the support platform and the electromechanical equipment components, adjusting their front and rear positions.

[0004] Regarding the above-mentioned content, the following technical defects were found: Existing fixtures for machining electromechanical equipment cannot clamp and position workpieces of different sizes, which reduces the applicability of the fixtures. In the existing technology, the workpieces of electromechanical equipment need to be flipped for multi-face processing during the processing. However, since the workpieces are clamped and positioned by the fixture, they need to be manually flipped and adjusted, which reduces the processing efficiency of the electromechanical equipment and the practicality of the fixture. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a fixture for machining electromechanical equipment.

[0006] To solve the above technical problems, this utility model provides a fixture for machining electromechanical equipment, including: a worktable and a clamping and flipping structure. A plurality of support columns are fixedly connected to the lower surface of the worktable. The clamping and flipping structure is located on the upper surface of the worktable. The clamping and flipping structure includes a fixed base placed on the upper surface of the worktable. Two rotating shafts are rotatably inserted through the inner wall of the fixed base. One end of one of the rotating shafts is fixedly connected to a turntable. A connecting rod is rotatably connected to the turntable at a centrifugal position away from the rotating shaft. A welding plate is fixedly connected to the upper surface of the fixed base. A cylinder is fixedly connected to the lower surface of the short arm end of the welding plate. The output end of the cylinder is rotatably connected to one end of the connecting rod. An arched plate is fixedly connected to one end of a rotating shaft that is close to the other. A sliding hole is formed on the surface of the arched plate. Two clamping plates are slidably connected to the inner wall of the sliding hole. A lead screw is threaded through the side of the two clamping plates. The lead screw is rotatably connected to the inner wall of the sliding hole. A bidirectional thread is formed on the arc surface of the lead screw. A driven bevel gear is fixedly connected to the arc surface of the lead screw. A rotating rod is rotatably connected to one side of the arched plate. A driving bevel gear is fixedly connected to one end of the rotating rod. The driving bevel gear meshes with the driven bevel gear. A motor base is fixedly connected to one side of the arched plate. A servo motor is fixedly connected to the inner wall of the motor base. The output end of the servo motor is fixedly connected to the end of the rotating rod away from the driving bevel gear.

[0007] The above-mentioned components achieve the following effects: by setting up a clamping and flipping structure, two effects are achieved: first, the clamping plates can be automatically controlled to clamp and stabilize electromechanical equipment parts of different sizes, thus improving the applicability of the processing fixtures; second, after the electromechanical equipment parts are clamped by the fixtures, the parts can be automatically flipped without manual flipping, thus improving the practicality of the electromechanical equipment processing fixtures.

[0008] Preferably, a positioning plate is fixedly connected to one side of each of the two clamping plates, and a positioning rod is slidably passed through the side of the two positioning plates, the positioning rod being fixedly connected to one side of the arched plate.

[0009] The effect achieved by the above components is that when the clamping plate moves, the positioning plate fixed on the clamping plate will move along the arc surface of the positioning rod, thereby improving the stability of the clamping plate movement process.

[0010] Preferably, the fixed base has an arc-shaped hole on the side away from the turntable, the center of the arc-shaped hole is coaxial with the axis of rotation of the rotating shaft, the cross-section of the arc-shaped hole is half a circle arc, and a sliding rod is slidably connected to the inner wall of the arc-shaped hole, one end of the sliding rod is fixedly connected to one side of the arched plate.

[0011] The effect achieved by the above components is that when the rotating shaft drives the arched plate to rotate, the slide rod fixed on the arched plate will slide along the inner wall of the arc-shaped hole. Since the arc-shaped hole is set as a half-circle arc, the rotation angle of the arched plate can be limited.

[0012] Preferably, rubber pads are fixedly connected to the sides of the two clamping plates that are close to each other, and the rubber pads are adapted to the size of one side of the clamping plate.

[0013] The effect achieved by the above components is that the rubber pad can increase the friction on one side of the clamping plate, thereby improving the clamping plate's limiting effect on the electromechanical equipment parts.

[0014] Preferably, the surface of the workbench is provided with an auxiliary structure, which includes several insertion holes and two screws. The insertion holes are opened on the surface of the workbench, and the screws are slidably inserted into the inner wall of the insertion holes. The upper end of the screws is fixedly connected to the lower surface of the fixed seat. A threaded ring is threadedly connected to the arc surface of the screws, and a washer is fixedly connected to the upper surface of the threaded ring. The diameter of the washer is larger than the diameter of the threaded ring.

[0015] The effect achieved by the above components is that, by setting up auxiliary structures, personnel can easily adjust the position of the jig used for machining on the worktable and make the jig securely fixed on the worktable, so that the machine tool can be processed at different positions on the worktable as needed.

[0016] Preferably, the outer wall of the threaded ring is provided with a plurality of anti-slip patterns, which are evenly distributed on the outer wall of the threaded ring.

[0017] The effect achieved by the above components is that personnel can rotate the threaded ring with the help of the anti-slip texture, thus achieving convenient control of the threaded ring.

[0018] Preferably, a guide block is fixedly connected to the lower end of the screw, and the guide block is configured as a tapered structure.

[0019] The effect achieved by the above components is that by setting a tapered guide block at the lower end of the screw, the screw can be easily inserted into the socket due to the small size of the guide block.

[0020] Compared with related technologies, the jig for machining electromechanical equipment provided by this utility model has the following beneficial effects: This utility model provides a jig for machining electromechanical equipment. By setting a clamping and flipping structure, it achieves two effects: first, it can automatically control the clamping plates to hold electromechanical equipment parts of different sizes firmly, thus improving the applicability of the jig; second, after using the jig to clamp the electromechanical equipment parts, it can automatically flip the parts without manual flipping, thus improving the practicality of the jig for machining electromechanical equipment.

[0021] By setting up auxiliary structures, personnel can easily adjust the position of the jigs used for machining electromechanical equipment on the worktable and ensure that the jigs are fixed firmly on the worktable, so that the electromechanical equipment can be processed at different positions on the worktable as needed.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0026] Please see Figure 1 and Figure 2 The present invention provides a fixture for machining electromechanical equipment, comprising: a worktable 1 and a clamping and flipping structure 3, wherein a plurality of support columns 2 are fixedly connected to the lower surface of the worktable 1.

[0027] The clamping and flipping structure 3 is located on the upper surface of the worktable 1, and the surface of the worktable 1 is provided with an auxiliary structure 4.

[0028] In the embodiments of this utility model, please refer to Figures 3 to 5The clamping and flipping structure 3 includes a fixed base 301, which is placed on the upper surface of the workbench 1. Two rotating shafts 302 are rotatably mounted on the inner wall of the fixed base 301. One end of one rotating shaft 302 is fixedly connected to a turntable 303. A connecting rod 304 is rotatably connected to the centrifugal position of the turntable 303 away from the rotating shaft 302. A welding plate 305 is fixedly connected to the upper surface of the fixed base 301. A cylinder 306 is fixedly connected to the lower surface of the short arm end of the welding plate 305. The output end of the cylinder 306 is rotatably connected to one end of the connecting rod 304. An arched plate 309 is fixedly connected to the ends of the two rotating shafts 302 that are close to each other. A sliding hole 310 is opened on the surface of the arched plate 309, and the inner wall of the sliding hole 310 is slidably connected to... There are two clamping plates 311, and a lead screw 312 is threaded through the side of the two clamping plates 311. The lead screw 312 is rotatably connected to the inner wall of the sliding hole 310. The arc surface of the lead screw 312 is provided with a bidirectional thread. The arc surface of the lead screw 312 is fixedly connected to a driven bevel gear 313. A rotating rod 314 is rotatably threaded through one side of the arched plate 309. One end of the rotating rod 314 is fixedly connected to a driving bevel gear 315. The driving bevel gear 315 meshes with the driven bevel gear 313. A motor base 316 is fixedly connected to one side of the arched plate 309. A servo motor 317 is fixedly connected to the inner wall of the motor base 316. The output end of the servo motor 317 is fixedly connected to the end of the rotating rod 314 away from the driving bevel gear 315. By setting up the clamping and flipping structure 3, two effects are achieved: First, the clamping plates 311 can be automatically controlled to firmly clamp electromechanical equipment parts of different sizes, improving the applicability of the machining fixture; second, after the electromechanical equipment parts are clamped by the fixture, the parts can be automatically flipped without manual flipping, improving the practicality of the electromechanical equipment machining fixture. Positioning plates 319 are fixedly connected to one side of each of the two clamping plates 311, and a positioning rod 320 slides through the side of each positioning plate 319. The positioning rod 320 is fixedly connected to one side of the arched plate 309. When the clamping plates 311 move, the positioning plates 319 fixed to the clamping plates 311 move along the arc surface of the positioning rod 320, thereby improving the stability of the clamping plates 311 during movement. An arc-shaped hole 307 is provided on the side of the fixed base 301 away from the turntable 303. The center of the arc-shaped hole 307 is coaxial with the axis of rotation of the rotating shaft 302. The cross-section of the arc-shaped hole 307 is a half-circle arc. A slide rod 308 is slidably connected to the inner wall of the arc-shaped hole 307. One end of the slide rod 308 is fixedly connected to one side of the arched plate 309. When the rotating shaft 302 drives the arched plate 309 to rotate, the slide rod 308 fixed on the arched plate 309 will slide along the inner wall of the arc-shaped hole 307. Since the arc-shaped hole 307 is set as a half-circle arc, the rotation angle of the arched plate 309 can be limited. Rubber pads 318 are fixedly connected to the sides of the two clamping plates 311 that are close to each other. The size of the rubber pads 318 is adapted to one side of the clamping plate 311.The rubber pad 318 can increase the friction on one side of the clamping plate 311, thereby improving the limiting effect of the clamping plate 311 on the electromechanical equipment parts.

[0029] In the embodiments of this utility model, please refer to Figure 6 The auxiliary structure 4 includes several insertion holes 41 and two screws 42. The insertion holes 41 are formed on the surface of the worktable 1. The screws 42 are slidably inserted into the inner wall of the insertion holes 41. The upper end of the screw 42 is fixedly connected to the lower surface of the fixed seat 301. A threaded ring 43 is threadedly connected to the arc surface of the screw 42. A washer 45 is fixedly connected to the upper surface of the threaded ring 43. The diameter of the washer 45 is larger than the diameter of the threaded ring 43. By setting the auxiliary structure 4, the operator can easily adjust the position of the machining fixture on the worktable 1 and fix the fixture firmly on the worktable 1, so that the machining equipment can perform machining at different positions on the worktable 1 as needed. Several anti-slip patterns 44 are formed on the outer wall of the threaded ring 43. The anti-slip patterns 44 are evenly distributed on the outer wall of the threaded ring 43. The operator can rotate the threaded ring 43 with the help of the anti-slip patterns 44, achieving the effect of convenient control of the threaded ring 43. A guide block 46 is fixedly connected to the lower end of the screw 42. The guide block 46 is designed with a tapered structure. By providing a tapered guide block 46 at the lower end of the screw 42, the screw 42 can be easily inserted into the socket 41 due to the small size of the guide block 46. The working principle of the fixture for machining electromechanical equipment provided by this utility model is as follows: When it is necessary to use the fixture to clamp and limit the electromechanical equipment parts, the electromechanical equipment parts are first placed on the arch plate 309, and then the servo motor 317 is started to drive the rotating rod 314 to rotate. The rotating rod 314 drives the active bevel gear 315 to rotate. The active bevel gear 315 drives the driven bevel gear 313 to rotate. The driven bevel gear 313 drives the lead screw 312, so that the lead screw 312 rotates along the inner wall of the sliding hole 310. During the rotation of the lead screw 312, it will drive the two clamping plates 3 11. Move the two clamping plates 311 towards each other simultaneously. Once the clamping plates 311 and the rubber pads 318 have firmly clamped the electromechanical parts, stop the servo motor 317. When the electromechanical parts need to be reversed during processing, first start the cylinder 306 to drive the connecting rod 304 to rotate. The connecting rod 304 drives the turntable 303 to rotate. The turntable 303 drives the rotating shaft 302 to rotate along the inner wall of the fixed seat 301. The rotating shaft 302 drives the arched plate 309 and the electromechanical parts to rotate. When the electromechanical parts are reversed... After rotating to the appropriate angle, the cylinder 306 can be stopped. After the machining of the electromechanical equipment parts is completed, the servo motor 317 is started to drive the active bevel gear 315 to rotate in the opposite direction. The active bevel gear 315 drives the driven bevel gear 313 to rotate in the opposite direction. The driven bevel gear 313 drives the lead screw 312 to rotate in the opposite direction. The lead screw 312 drives the two clamping plates 311 to move simultaneously in a direction away from each other. When the clamping plates 311 separate the rubber pad 318 from the electromechanical equipment parts, the electromechanical equipment parts can be removed. During the movement of the clamping plates 311, the parts are fixed in place. The positioning plate 319 on 311 moves along the arc surface of the positioning rod 320, thereby improving the stability of the movement of the clamping plate 311. In addition, when the rotating shaft 302 drives the arched plate 309 to rotate, the sliding rod 308 fixed on the arched plate 309 slides along the inner wall of the arc-shaped hole 307. Since the arc-shaped hole 307 is set as a half-circle arc, the rotation angle of the arched plate 309 can be limited. Finally, the rubber pad 318 can increase the friction on one side of the clamping plate 311, thereby improving the limiting effect of the clamping plate 311 on the electromechanical equipment parts.

[0030] When it is necessary to adjust the position of the machining fixture on the worktable 1, first rotate the adjusting ring to move the shim 45 along the arc surface of the screw 42, causing the threaded ring 43 to separate from the screw 42. Then move the fixed seat 301 to move the screw 42, causing the screw 42 to separate from the insertion hole 41 on the worktable 1. After the screw 42 separates from the insertion hole 41, the position of the fixed seat 301 can be moved. After the fixed seat 301 is moved to the appropriate position, the screw 42 is then inserted into the corresponding screw hole. Then, the adjusting ring is placed on the arc surface of the screw 42, and finally the threaded ring 43 is rotated to drive the shim 45 to abut against the lower surface of the worktable 1, thus completing the adjustment of the fixture position. In this way, by setting a tapered guide block 46 at the lower end of the screw 42, the screw 42 can be easily inserted into the insertion hole 41 due to the small size of the guide block 46. In addition, the operator can rotate the threaded ring 43 with the help of the anti-slip texture 44, thus achieving the effect of convenient control of the threaded ring 43.
