Description

Technical Field

[0001] This utility model relates to the field of clamping technology for motor controller processing, and more specifically, it relates to a clamping device for motor controller processing. Background Technology

[0002] In existing technologies, motor controllers are core control devices used to control important functions such as motor operation, speed regulation, and power distribution. The clamping device used in motor controller processing is a crucial tooling for stably clamping and fixing the controller body or key components during production. It needs to reliably position and clamp the workpiece to ensure processing accuracy and quality. However, in actual motor controller production, due to differences in size between batches, changes in processing technology, equipment maintenance, and wear and aging of the clamping device, disassembly, maintenance, and even replacement of the clamping device are frequently required. In existing technologies, the clamping device for motor controller processing typically uses traditional fixing methods such as bolt fastening. Disassembly and assembly usually require the use of wrenches, screwdrivers, and specialized disassembly tools, involving multiple rotations and repetitive steps. This process is cumbersome and time-consuming. Furthermore, in cases of incompatible tool models, incomplete tool configuration, or lost or damaged tools, timely disassembly, maintenance, or even replacement of the clamping device can be impossible, impacting production progress and equipment maintenance efficiency.

[0003] Secondly, while some improved clamping devices for motor controller machining in the existing technology have achieved tool-free disassembly, maintenance, and replacement of the clamping frame to a certain extent by adopting certain devices, the structural stability and locking reliability of the fixed clamping frame are lacking. In actual use, the clamping device for motor controller machining will frequently be subjected to various dynamic external forces such as cutting forces, vibration impacts, clamping force fluctuations, and shaking and bumping during equipment movement. In addition, there may be adverse factors such as accidental contact by operators. These simple structures and unstable quick-locking mechanisms and tool-free disassembly devices are prone to loosening of the locking structure of the fixed clamping frame, failure of the connecting mechanism, or even accidental unlocking and detachment due to external force impacts, equipment vibrations, accidental contact, processing force fluctuations, or equipment operation. This not only affects the stability and processing accuracy of motor controller machining, but may also lead to adverse effects such as clamping frame detachment and damage, displacement of the processed object, reduction in processing quality, and equipment safety hazards.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a clamping device for processing motor controllers, comprising a movable frame, a fastening sleeve detachably provided on one side of the movable frame, a clamping frame detachably provided on one side of the movable frame, a fastening rod detachably provided on the inner side of the fastening sleeve, a release sleeve slidably provided on the outer side of the fastening sleeve, a fastening groove provided on the outer side of the fastening rod, a mating sleeve rotatably provided on one side of the fastening sleeve, a driving gear connected to one side of the mating sleeve, an auxiliary groove provided on the inner side of the fastening sleeve, a compression spring and a fastening block movably provided in the auxiliary groove, both ends of the compression spring being connected to the inner wall of the auxiliary groove and one end of the fastening block respectively, and one end of the fastening block being inserted into the fastening groove, a screw rod connected to one side of the release sleeve, a threaded sleeve movably connected to the outer side of the screw rod, a driven gear fixedly connected to one side of the threaded sleeve, multiple driven gears meshing with the driving gear, sliding grooves provided on both sides of the auxiliary groove, an auxiliary block fixedly provided on the inner side of the release sleeve, and a control groove provided on the inner side of the fastening sleeve.

[0006] The present invention is further configured such that a plurality of push springs are connected to one side of the clamping frame, and a clamping plate is connected to the other end of the push springs, wherein the clamping surface of the clamping plate is made of rubber.

[0007] The present invention is further configured such that a drive shaft is rotatably provided at the bottom end of the mobile frame, and a transmission gear is detachably connected to the outer ends of both drive shafts. A drive assembly is detachably provided at the bottom end of the mobile frame, and the output end of the drive assembly is respectively connected to one end of the drive shafts provided on both sides. A base is provided below the mobile frame, and a rack is detachably provided on the base, with the transmission gear meshing with the rack.

[0008] The present invention is further configured such that a slider is detachably provided at the bottom of the mobile frame, and a slide rail is detachably provided on the upper side of the base, and the slider is slidably mounted on the slide rail.

[0009] The present invention is further configured such that sliding rods are fixedly connected to both sides of the fastening block, and the sliding rods slide in the sliding groove.

[0010] The present invention is further configured such that an mounting plate is fixedly provided on the outer side of the fastening sleeve, and a plurality of the screw sleeves are rotatably mounted on the mounting plate.

[0011] The present invention is further configured such that the auxiliary block slides in the control groove, and the outer wall of the sliding rod is in contact with one side of the auxiliary block.

[0012] The present invention is further provided that a plurality of rubber strips are fixedly provided on the outer side of the mating sleeve.

[0013] (III) Beneficial Effects Compared with the prior art, the present invention provides a clamping device for machining motor controllers, which has the following advantages: 1. A tool-free quick disassembly and assembly system, consisting of components such as a release sleeve, fastening sleeve, fastening rod, auxiliary block, compression spring, fastening block, and sliding rod, allows operators to easily disassemble and assemble the clamping frame by simply rotating and pulling. The entire process requires no auxiliary tools such as wrenches or screwdrivers; the disassembly and assembly of the clamping frame can be completed manually. This effectively solves the technical defects of existing technologies, which require multiple auxiliary tools for multi-step repetitive operations, have cumbersome and time-consuming procedures, and cannot achieve timely disassembly and maintenance when tools are unsuitable or incomplete. This improves the convenience and efficiency of clamping frame disassembly and assembly, and avoids the adverse effects of tool problems on production progress and equipment maintenance efficiency.

[0014] 2. By setting up a locking mechanism composed of components such as a screw, threaded sleeve, mating sleeve, driving gear, and driven gear, after the clamping frame is installed, the threaded engagement between the screw and the threaded sleeve prevents the release sleeve from sliding easily. The release sleeve limits the sliding rod through an auxiliary block, keeping the fastening block stable. The locking mechanism effectively resists various dynamic external forces during processing, such as cutting forces, vibration impacts, clamping force fluctuations, shaking and bumping during equipment movement, and accidental contact by operators. It effectively solves the technical defects of existing tool-free disassembly and assembly devices, such as lack of structural stability and locking reliability, and easy loosening or even accidental unlocking and detachment of the locking structure due to external impacts or equipment vibrations. It ensures the structural stability and locking reliability of the clamping frame after installation, and avoids adverse effects such as clamping frame detachment and damage, displacement of the workpiece, reduction in processing quality, and equipment safety hazards.

[0020] Please see Figures 1-5 A clamping device for machining a motor controller includes a movable frame 1. A fastening sleeve 2 is detachably provided on one side of the movable frame 1, and a clamping frame 3 is detachably provided on one side of the movable frame 1. A fastening rod 4 is detachably provided inside the fastening sleeve 2, and a release sleeve 5 is slidably sleeved on the outside of the fastening sleeve 2. A fastening groove 6 is formed on the outside of the fastening rod 4. A mating sleeve 7 is rotatably provided on one side of the fastening sleeve 2, and a drive gear 8 is connected to one side of the mating sleeve 7. An auxiliary groove 9 is formed inside the fastening sleeve 2, and a compression spring 10 and a fastening block 11 are movably arranged in the auxiliary groove 9. The compression spring 10 is connected to the inner wall of the auxiliary groove 9 and one end of the fastening block 11 respectively. One end of the fastening block 11 is inserted into the fastening groove 6. A screw 12 is connected to one side of the release sleeve 5. A threaded sleeve 13 is connected to the outside of the screw 12 through a thread. A driven gear 14 is fixedly connected to one side of the threaded sleeve 13. Multiple driven gears 14 mesh with the driving gear 8. Sliding grooves 15 are opened on both sides of the auxiliary groove 9. An auxiliary block 16 is fixedly installed inside the release sleeve 5. A control groove 17 is opened inside the fastening sleeve 2.

[0021] Multiple push springs 18 are connected to one side of the clamping frame 3, and a clamping plate 19 is connected to the other end of the push spring 18. The clamping surface of the clamping plate 19 is made of rubber.

[0022] The bottom of the mobile frame 1 is provided with a drive shaft 20 that can be rotated. The outer ends of the two drive shafts 20 can be detachably connected to a transmission gear 21. The bottom of the mobile frame 1 is provided with a drive assembly 22 that can be detachably connected to one end of the drive shafts 20 on both sides. The bottom of the mobile frame 1 is provided with a base 23. A rack 24 is detachably provided on the base 23. The transmission gear 21 meshes with the rack 24. The bottom of the mobile frame 1 is detachably equipped with a slider 25, and the upper side of the base 23 is detachably equipped with a slide rail 26. The slider 25 is slidably mounted on the slide rail 26.

[0023] In this embodiment, when the clamping frame 3 needs to be removed, the mating sleeve 7 is first rotated forward, causing the mating sleeve 7 to drive the one-sided driving gear 8 to rotate forward. Then, the driving gear 8 will drive the multiple driven gears 14 meshing with it to rotate in the opposite direction. Then, the driven gears 14 will drive the threaded sleeve 13 to rotate in the opposite direction on the mounting plate 28. Since the threaded sleeve 13 and the screw 12 are connected by threads, and the multiple screws 12 are arranged so that the screw 12 will not rotate, the screw 12 will drive the release sleeve 5 connected to one side to slide. At the same time, the release sleeve 5 will drive the inner auxiliary block 16 to slide along the control groove 17, and compress the spring. 10 will gradually reset, causing the compression spring 10 to pull the fastening block 11 to slide into the inner side of the auxiliary groove 9. The fastening block 11 will drive the sliding rods 27 on both sides to slide along the sliding groove 15, so that the outer wall of the sliding rod 27 is always in contact with one side of the auxiliary block 16. At the same time, the fastening block 11 will gradually detach from the fastening groove 6. After the fastening block 11 is completely detached from the fastening groove 6, the fastening sleeve 2 can be removed by pulling it to one side. Then, the fastening rod 4 can be removed by pulling it to the other side. Then, the other fastening sleeves 2 and fastening rods 4 can be removed by following the above steps. Then, the clamping frame 3 can be removed from the moving frame 1.

[0024] Please see Figures 3-5 As a further implementation of the overall equipment: the fastening block 11 is fixedly connected to both sides with sliding rods 27, which slide in the sliding groove 15.

[0025] A mounting plate 28 is fixedly provided on the outside of the fastening sleeve 2, and multiple screw sleeves 13 are rotatably mounted on the mounting plate 28.

[0026] The auxiliary block 16 slides in the control groove 17, and the outer wall of the sliding rod 27 is in contact with one side of the auxiliary block 16.

[0027] Multiple rubber strips 29 are fixed on the outer side of the sleeve 7.

[0028] More specifically, when it is necessary to reinstall the clamping frame 3, first place the clamping frame 3 in the corresponding position on the movable frame 1, and align the pre-drilled mounting holes on the clamping frame 3 with the pre-drilled mounting holes on the movable frame 1. Then, pass the fastening rod 4 through the corresponding pre-drilled mounting holes on the movable frame 1 and the clamping frame 3 from one side. Then, fit the fastening sleeve 2 onto the outside of the fastening rod 4 from the other side. Then, rotate the mating sleeve 7 in the reverse direction, causing the mating sleeve 7 to drive the driving gear 8 on one side to rotate in the reverse direction. Then, the driving gear 8 drives the driven gear 14 meshing with it to rotate in the forward direction, causing the driven gear 14 to drive the threaded sleeve. 13 rotates forward on the mounting plate 28, and then the screw 12 slides back to its original position through the threaded engagement. The screw 12 then drives the release sleeve 5 to slide back to its original position, causing the release sleeve 5 to drive the inner auxiliary block 16 to slide back to its original position in the control groove 17. The auxiliary block 16 pushes the sliding rod 27 to slide along the sliding groove 15. The sliding rod 27 then drives the fastening block 11 to gradually slide out of the auxiliary groove 9. Simultaneously, the fastening block 11 drives the compression spring 10 connected to one end to stretch, causing the fastening block 11 to re-engage in the fastening groove 6. The engagement of the screw 12 and the threaded sleeve 13 releases... Sleeve 5 cannot slide easily, and the release sleeve 5 limits the sliding rod 27 through the inner auxiliary block 16, so that the sliding rod 27 and the fastening block 11 will not move, achieving a stable connection. Then, follow the above steps to engage the other fastening sleeves 2 and fastening rods 4, thereby achieving a stable installation of the clamping frame 3. The drive component 22 is a dual-head output motor. Since the clamping device is a mature technology in the prior art, the specific operating principle of the clamping device will not be described in detail in this article. When clamping is required, first place the workpiece to be clamped between the two clamping plates 19, and then simultaneously open the two drive components. The driving component 22 causes the two driving components 22 to rotate synchronously in opposite directions. Then, the driving component 22 drives the transmission gear 21 to rotate through the drive shaft 20. Due to the meshing of the transmission gear 21 and the rack 24, the moving frame 1 will drive the bottom slider 25 to slide along the slide rail 26, so that the two moving frames 1 move inward synchronously. Then, the inner wall clamping surfaces of the two clamping plates 19 first contact the outer wall of the workpiece. Then, the clamping plates 19 stop moving, and the clamping frame 3 continues to move with the moving frame 1, so that the clamping frame 3 and the clamping plate 19 cooperate to squeeze the push spring 18. After the clamping is stable, the driving component 22 can be turned off.

[0029] In summary, during the use or operation of the overall equipment: when it is necessary to remove the clamping frame 3, first rotate the mating sleeve 7 in the forward direction, causing the mating sleeve 7 to drive the one-sided driving gear 8 to rotate in the forward direction. Then, the driving gear 8 will drive the multiple driven gears 14 meshing with it to rotate in the reverse direction. Then, the driven gears 14 will drive the threaded sleeve 13 to rotate in the reverse direction on the mounting plate 28. Since the threaded sleeve 13 and the screw 12 are connected by threads, and the multiple screws 12 are arranged so that the screw 12 will not rotate, the screw 12 will then drive the release sleeve 5 connected to one side to slide. At the same time, the release sleeve 5 will drive the inner auxiliary block 16 to slide along the control groove 17. The compression spring 10 will gradually reset, causing the compression spring 10 to pull the fastening block 11 to slide into the inner side of the auxiliary groove 9. The fastening block 11 will drive the sliding rods 27 on both sides to slide along the sliding groove 15, so that the outer wall of the sliding rod 27 is always in contact with one side of the auxiliary block 16. At the same time, the fastening block 11 will gradually detach from the fastening groove 6. After the fastening block 11 is completely detached from the fastening groove 6, the fastening sleeve 2 can be removed by pulling it to one side. Then, the fastening rod 4 can be removed by pulling it to the other side. Then, the other fastening sleeves 2 and fastening rods 4 can be removed by following the above steps. Then, the clamping frame 3 can be removed from the moving frame 1.

[0030] When it is necessary to reinstall the clamping frame 3, first place the clamping frame 3 in the corresponding position on the movable frame 1, and align the pre-drilled mounting holes on the clamping frame 3 with the pre-drilled mounting holes on the movable frame 1. Then, pass the fastening rod 4 through the corresponding pre-drilled mounting holes on the movable frame 1 and the clamping frame 3 from one side. Then, fit the fastening sleeve 2 onto the outside of the fastening rod 4 from the other side. Next, rotate the mating sleeve 7 in the reverse direction, causing the mating sleeve 7 to drive the one-sided drive gear 8 to rotate in the reverse direction. Then, the drive gear 8 drives the driven gear 14 meshing with it to rotate in the forward direction, causing the driven gear 14 to drive the threaded sleeve 13 to rotate in the installation position. The mounting plate 28 is rotated in the forward direction, and then the screw 12 slides back to its original position through the threaded engagement. The screw 12 then drives the release sleeve 5 to slide back to its original position, causing the release sleeve 5 to drive the inner auxiliary block 16 to slide back to its original position in the control groove 17. The auxiliary block 16 pushes the sliding rod 27 to slide along the sliding groove 15. The sliding rod 27 then drives the fastening block 11 to gradually slide out of the auxiliary groove 9. Simultaneously, the fastening block 11 drives the compression spring 10 connected to one end to stretch, causing the fastening block 11 to re-engage in the fastening groove 6. The engagement of the screw 12 and the threaded sleeve 13 allows the release sleeve 5 to... The slide bar 27 can be easily slid, and the release sleeve 5 limits the sliding rod 27 through the inner auxiliary block 16, so that the sliding rod 27 and the fastening block 11 will not move, achieving a stable connection. Then, follow the above steps to engage the other fastening sleeves 2 and fastening rods 4, thereby achieving a stable installation of the clamping frame 3. The drive assembly 22 is a dual-head output motor. Since the clamping device is a mature technology in the prior art, the specific operating principle of the clamping device will not be described in detail in this article. When clamping is required, first place the workpiece to be clamped between the two clamping plates 19, and then simultaneously open the two drive assemblies. The component 22 causes the two drive components 22 to rotate synchronously in opposite directions. Then, the drive component 22 drives the transmission gear 21 to rotate through the drive shaft 20. Due to the meshing of the transmission gear 21 and the rack 24, the moving frame 1 will drive the bottom slider 25 to slide along the slide rail 26, so that the two moving frames 1 move inward synchronously. Then, the inner wall clamping surfaces of the two clamping plates 19 first contact the outer wall of the workpiece. Then, the clamping plates 19 stop moving, and the clamping frame 3 continues to move with the moving frame 1, so that the clamping frame 3 and the clamping plate 19 cooperate to squeeze the push spring 18. After the clamping is stable, the drive component 22 can be turned off.

For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
