Description
Technical Field
[0001] This utility model belongs to the field of die casting processing technology, and in particular relates to a fixing device for die casting processing. Background Technology
[0002] Fixtures for die casting are specialized tooling equipment used for precise positioning and stable clamping of die castings during the machining process. By adapting to the shape, size, and processing requirements of the die castings, they ensure that the die castings maintain a stable posture during machining processes such as cutting, drilling, and grinding, preventing deviations in machining accuracy or safety hazards caused by displacement or vibration. At the same time, they facilitate efficient and precise machining of die castings by automated processing equipment or manual operation, making them an important auxiliary device for ensuring the quality and production efficiency of die casting processing.
[0003] However, in the use of existing equipment, the angle of its fixing device is difficult to adjust. When it is necessary to adjust the processing angle of the die casting according to the actual needs of the workpiece specifications and processing procedures in the actual production scenario, the operation process is not only cumbersome and consumes a lot of manual time, but it is also difficult to guarantee the accuracy of the angle adjustment. This will affect the processing quality of the die casting and even cause deviations in subsequent processes, which will have an adverse impact on production efficiency and product qualification rate. Utility Model Content
[0004] The purpose of this utility model is to provide a fixing device for die casting processing. By setting an adjustment part, it solves the problem that the angle of the fixing device is difficult to adjust. When it is necessary to adjust the processing angle of the die casting according to the actual needs of the workpiece specifications and processing procedures in the actual production scenario, the operation process is not only cumbersome and consumes a lot of manual time, but it is also difficult to ensure the accuracy of the angle adjustment. This will affect the processing quality of the die casting and even cause deviations in subsequent processes, which will have an adverse impact on production efficiency and product qualification rate.
[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a fixing device for die-casting part processing, including a worktable, and further comprising: an adjusting part disposed on the top of the worktable; a clamping part disposed on the top of the adjusting part; the adjusting part including an adjusting assembly mounted on the top of the worktable; and a limiting assembly mounted on the adjusting assembly; the adjusting assembly including a support frame fixedly connected to the top of the worktable, a rotating rod rotatably connected to the support frame, a rotating block sleeved on the outer wall of the rotating rod, and an adjusting plate fixedly connected to the top of the rotating block; the rotating rod... Two gears are fitted on the outer wall. Two slide rails are fixedly connected to the top of the worktable. Racks are slidably connected to the outer surfaces of the two slide rails. The two racks mesh with the two gears. Connecting plates are fixedly connected to the front of the two racks. A driving component is provided on the support frame. The left and right ends of the rotating rod extend outside the support frame and are rotatably connected to the support frame. The driving component includes a hydraulic push rod provided on the support frame. The output end of the hydraulic push rod is fixedly connected to the connecting plate. A hoop is provided on the outer wall of the hydraulic push rod and is fixedly connected to the support frame.
[0006] Furthermore, the clamping part includes a clamping assembly mounted on top of the adjusting plate; and a driving assembly mounted on the clamping assembly.
[0007] Furthermore, the limiting assembly includes a support plate fixedly connected to the top of the workbench. The support plate has several limiting holes. A limiting plate is fixedly connected to the outer wall of the rotating rod. A limiting rod is slidably connected to the limiting plate. The right end of the limiting rod extends into the corresponding limiting hole and is slidably connected to the corresponding limiting hole. The left end of the rotating rod extends out of the support plate and is rotatably connected to the support plate. The support plate at the top of the workbench provides stable support for the rotating rod. The rotatable connection between the left end of the rotating rod and the support plate ensures smooth rotation of the rotating rod. The limiting plate on the outer wall of the rotating rod is slidably connected to the limiting rod. The right end of the limiting rod can extend into the corresponding limiting hole on the support plate. The engagement between the limiting rod and the limiting hole restricts the rotation of the rotating rod and prevents accidental deviation of the rotating rod.
[0008] Furthermore, the clamping assembly includes a rectangular plate fixedly connected to the top of the adjusting plate. Two slide rails are fixedly connected to the front of the rectangular plate, and two sliding plates are slidably connected to the outer surfaces of the two slide rails. Anti-slip clamping plates are fixedly connected to the front of each of the two sliding plates. A transmission component is provided on each of the two sliding plates. Anti-slip textures are provided on the anti-slip clamping plates. Each transmission component includes a connecting rod hinged to the back of each of the two sliding plates. The ends of the two connecting rods away from the sliding plates are hinged to connecting rods. The two slide rails on the top rectangular plate of the adjusting plate provide stable sliding guidance for the sliding plates, ensuring smooth movement of the anti-slip clamping plates. The anti-slip textures on the anti-slip clamping plates enhance clamping friction and prevent the clamped object from slipping. The two sliding plates are hinged to connecting rods on their backs to form a linkage structure, which can synchronously drive the opening and closing of the two clamping plates, achieving symmetrical clamping of the object and ensuring balanced force.
[0009] Furthermore, the drive assembly includes a motor mounted on a rectangular plate. The output shaft of the motor is fixedly connected to a rotating shaft via a coupling. A connecting rod 2 is sleeved on the outer wall of the rotating shaft. A motor slot is provided on the rectangular plate, and the motor is located in the motor slot. The motor in the motor slot of the rectangular plate drives the rotating shaft to rotate via the coupling, causing the connecting rod 2 sleeved on the outer wall of the rotating shaft to rotate synchronously, providing power for the sliding of the slide plate in the clamping assembly, and driving the anti-slip clamping plate to open and close.
[0010] This utility model has the following beneficial effects: 1. By setting an adjustment section, when the machining angle needs to be adjusted after the die-casting part is fixed, first pull out the limiting rod on the outer wall limit plate of the rotating rod to release the limitation on the limit plate and the rotating rod. Then, start the hydraulic push rod, which drives the two racks to slide back and forth along the slide rail through the connecting plate. Because the racks mesh with the gears on the rotating rod, the rotating rod, the rotating block and the die-casting part on the adjustment plate will adjust the angle synchronously. After the die-casting part is adjusted to the appropriate angle, insert the limiting rod into the limit hole corresponding to the limit plate and the support plate to fix the limit plate to fix the rotating rod synchronously, preventing the die-casting part from rotating accidentally during processing. This setting can flexibly and accurately adjust the machining angle of the die-casting part to meet the needs of various processes, while ensuring the stability and machining accuracy after the angle is fixed. 2. By setting up a clamping part, when in use, place the die-cast part to be processed on the top of the adjusting plate, start the motor, and the motor drives the connecting rod two to rotate counterclockwise through the rotating shaft. Because the connecting rod two is hinged to two connecting rods one, and the other end of the connecting rod one is hinged to the slide plate on the slide rail two, when the motor drives the connecting rod two to rotate, it will be transmitted through the two connecting rods one, so that the two slide plates synchronously drive the anti-slip clamping plates to move closer to each other along the slide rail two, and firmly clamp the die-cast part. This setting can quickly clamp and fix die-cast parts of different specifications, ensure the stability of the workpiece during processing, and at the same time reduce the manual operation intensity of fixing.

[0015] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0016] Please see Figure 1-5As shown, this utility model is a fixing device for die casting processing, including a worktable 1, and further including: an adjustment part 2, which is disposed on the top of the worktable 1; and a clamping part 3, which is disposed on the top of the adjustment part 2. The adjustment unit 2 includes an adjustment assembly 21, which is mounted on the top of the workbench 1; and a limiting assembly 22, which is mounted on the adjustment assembly 21. The adjustment assembly 21 includes a support frame 211 fixedly connected to the top of the workbench 1. A rotating rod 212 is rotatably connected to the support frame 211. A rotating block 213 is sleeved on the outer wall of the rotating rod 212. An adjustment plate 214 is fixedly connected to the top of the rotating block 213. Two gears 215 are sleeved on the outer wall of the rotating rod 212. Two slide rails 216 are fixedly connected to the top of the workbench 1. A rack 217 is slidably connected to the outer surface of each of the two slide rails 216. Each rack 217 meshes with one of the two gears 215. The front surfaces of the two racks 217 are fixedly connected to... The system includes a connecting plate 218, a driving component on a support frame 211, and a rotating rod 212 whose left and right ends extend outside the support frame 211 and are rotatably connected to it. A limiting assembly 22 includes a support plate 221 fixedly connected to the top of the workbench 1, with several limiting holes 222 on the support plate 221. A limiting plate 223 is fixedly connected to the outer wall of the rotating rod 212, and a limiting rod 224 is slidably connected to the limiting plate 223. The right end of the limiting rod 224 extends into the corresponding limiting hole 222 and is slidably connected to it. The left end of the rotating rod 212 extends outside the support plate 221 and is rotatably connected to it. The driving component includes a hydraulic push rod 2 on the support frame 211. 19. The output end of the hydraulic push rod 219 is fixedly connected to the connecting plate 218. The outer wall of the hydraulic push rod 219 is provided with a hoop, and the hoop is fixedly connected to the support frame 211. By setting the adjustment part 2, after the die-casting part is fixed, if it is necessary to adjust its angle according to the actual processing requirements, the limiting rod 224 fixed on the limiting plate 223 on the outer wall of the rotating rod 212 can be pulled out first, so that the limiting plate 223 and the rotating rod 212 are released from the limit, so as to avoid affecting the angle adjustment operation. Then, the hydraulic push rod 219 is started. The hydraulic push rod 219 will drive the two racks 217 connected to it to slide back and forth along the outer surface of the two slide rails 216 through the connecting plate 218. Since the two racks 217 are respectively connected to the two gears on the rotating rod 212, The gears 215 mesh with each other. Therefore, when the hydraulic push rod 219 drives the rack 217 to slide, the gear 215 meshing with it will drive the rotating rod 212, the rotating block 213 and the die-casting parts on the adjusting plate 214 to adjust their angles synchronously. After the die-casting parts are adjusted to the appropriate angle, the limiting rod 224 can be inserted into the limiting plate 223 on the rotating rod 212 and the limiting hole 222 corresponding to the support plate 221. By fixing the limiting plate 223, the rotating rod 212 is synchronously fixed, thereby preventing the die-casting parts from rotating accidentally during processing. With this setting, the precise adjustment of the processing angle of the die-casting parts can be achieved flexibly and conveniently, meeting the diverse angle requirements of different processing procedures, while ensuring the stability after the angle is fixed and ensuring processing accuracy.
[0017] The clamping part 3 includes a clamping assembly 31, which is mounted on the top of the adjusting plate 214; and a driving assembly 32, which is mounted on the clamping assembly 31. The clamping assembly 31 includes a rectangular plate 311 fixedly connected to the top of the adjusting plate 214. Two slide rails 312 are fixedly connected to the front of the rectangular plate 311. Two sliding plates 313 are slidably connected to the outer surfaces of the two slide rails 312. Anti-slip clamping plates 314 are fixedly connected to the front of each of the two sliding plates 313. Each of the two slide plates 313 is equipped with a transmission component. The anti-slip clamping plate 314 is provided with anti-slip texture. The drive assembly 32 includes a motor 321 mounted on the rectangular plate 311. The output shaft of the motor 321 is fixedly connected to a rotating shaft 322 via a coupling. A connecting rod 323 is sleeved on the outer wall of the rotating shaft 322. A motor slot is provided on the rectangular plate 311, and the motor 321 is located in the motor slot. The transmission component includes a connecting rod 315 that is hinged to the back of both slide plates 313. The two connecting rods 315 are far from each other. One end of the slide plate 313 is hinged to the second connecting rod 323. By setting the clamping part 3, the die-casting part to be processed can be placed on the top of the adjusting plate 214 during use. After placement, the motor 321 can be started. The motor 321 will drive the second connecting rod 323 to rotate counterclockwise through the rotating shaft 322. Since there are two connecting rods 315 hinged on the second connecting rod 323, and the other ends of the two connecting rods 315 are hinged to the two slide plates 313 sliding on the two slide rails 312, during the process of the motor 321 driving the second connecting rod 323 to rotate through the rotating shaft 322, the two slide plates 313 hinged to them can be driven by the transmission of the two connecting rods 315 to move the anti-slip clamping plates 314 on them to slide closer to each other along the two slide rails 312, thereby firmly clamping the die-casting part placed therein. With this setting, the die-casting parts of different specifications can be quickly clamped and fixed, ensuring the stability of the workpiece during processing, while reducing the intensity of manual fixing.
[0018] One specific application of this embodiment is as follows: During use, the die-cast part to be processed can be placed on top of the adjusting plate 214. After placement, the motor 321 can be started. The motor 321 will drive the connecting rod 2 323 to rotate counterclockwise via the rotating shaft 322. Since two connecting rods 1 315 are hinged to the connecting rod 2 323, and the other ends of both connecting rods 1 315 are hinged to two sliding plates 313 sliding on the two slide rails 2 312, during the process of the motor 321 driving the connecting rod 2 323 to rotate via the rotating shaft 322, Through the transmission of two connecting rods 315, the two hinged sliding plates 313 synchronously drive the anti-slip clamping plates 314 on them to slide closer to each other along the two slide rails 312, thereby firmly clamping the die-casting parts placed therein. This setting enables quick clamping and fixing of die-casting parts of different specifications, ensuring the stability of the workpiece during processing, while reducing the manual fixing operation intensity. After the die-casting parts are fixed, if it is necessary to adjust their angle according to actual processing requirements, the limiting plate 22 fixed to the outer wall of the rotating rod 212 can be pulled out first. The limiting rod 224 on the 3rd section releases the limiting plate 223 and the rotating rod 212 from their limits, preventing interference with the angle adjustment operation. Then, the hydraulic push rod 219 is activated. The hydraulic push rod 219, through the connecting plate 218, drives the two racks 217 connected to it to slide back and forth along the outer surfaces of the two slide rails 216. Since the two racks 217 mesh with the two gears 215 on the rotating rod 212 respectively, when the hydraulic push rod 219 drives the racks 217 to slide, the meshing gears 215 will drive the rotating rod 212, the rotating block 213, and the adjusting plate. The die-casting part on 214 is adjusted at the same angle. After the die-casting part is adjusted to the appropriate angle, the limiting rod 224 can be inserted into the limiting plate 223 on the rotating rod 212 and the limiting hole 222 corresponding to the support plate 221. The rotating rod 212 is fixed at the same time by fixing the limiting plate 223, thereby preventing the die-casting part from rotating accidentally during the processing. With this setting, the precise adjustment of the processing angle of the die-casting part can be realized flexibly and conveniently, meeting the diverse angle requirements of different processing procedures, while ensuring the stability after the angle is fixed and ensuring the processing accuracy.
