Description

Technical Field

[0001] This invention belongs to the technical field of commutator processing equipment, specifically referring to a commutator part side groove processing equipment. Background Technology

[0002] Commutator is a core component of motor. Its side usually needs to be filled with multiple evenly distributed grooves to meet the requirements of winding, heat dissipation and assembly positioning. The machining accuracy and efficiency of the grooves directly affect the overall performance and production cycle of the commutator and even the motor.

[0003] Existing commutator side groove processing equipment has a single and fixed processing mode. Most equipment adopts a single-station or dual-station design, which can only perform groove processing on one or two sets of commutators at a time. After processing, the machine needs to be stopped to unload the finished product and clamp the new workpiece. The clamping and processing waiting time accounts for a high proportion, which significantly reduces the overall production efficiency and makes it difficult to adapt to the large-scale production needs of commutators. Summary of the Invention

[0004] In view of the above situation and to overcome the defects of the prior art, the purpose of the present invention is to provide a commutator part side groove processing equipment to at least partially solve the problems mentioned in the background art.

[0005] The technical solution adopted by this invention is as follows: This invention proposes a commutator component side groove processing equipment, comprising: The positioning cylinder has multiple sets of commutators stacked on its outer side, and the positioning cylinder has a sealed air chamber with adjustable air pressure inside. A push-pull rod is slidably mounted on the side wall of the positioning cylinder. Driven by changes in air pressure within the air chamber, it moves axially. The free end of the push-pull rod is provided with a fixed support plate. When the push-pull rod slides outward, it drives the fixed support plate to tighten and fix the commutator from the inside of the commutator. A drive cylinder is located above the positioning cylinder. A drive cavity is provided inside the drive cylinder. A rotating shaft is rotatably provided on the top wall of the drive cylinder. A pressure plate is fixed on the rotating shaft. The pressure plate can switch between a vertical state and a horizontal state as it rotates with the rotating shaft. In the horizontal state, it presses against the top of the stacked commutator. The lifting rod is slidably mounted on the top wall of the positioning cylinder and the bottom wall of the driving cylinder. It is driven to rise and fall by the change in air pressure in the air chamber. When the lifting rod rises and falls, the linkage shaft rotates, which drives the pressure plate to switch states.

[0006] Furthermore, a grooving mechanism is provided on one side of the positioning cylinder. The grooving mechanism includes a lifting frame, a lifting block, an electric telescopic rod, and a grooving cutter. The lifting block is configured to move up and down along the lifting frame. The electric telescopic rod is located on the lifting block, and the grooving cutter is located at the free end of the electric telescopic rod.

[0007] Furthermore, a lifting groove is provided on the side wall of the lifting frame, a lifting motor is provided on the lifting frame, a lifting screw is rotatably provided inside the lifting frame, one end of the lifting screw is connected to the output shaft of the lifting motor, a guide rod is provided on the lifting frame, and the lifting block is connected to the lifting screw by a thread and slidably disposed on the guide rod. Both ends of the lifting block are slidably disposed in the lifting groove. The lifting block can be driven to rise and fall along the lifting frame by the rotation of the lifting screw and the guidance of the guide rod, so as to continuously slot the stacked commutators.

[0008] Furthermore, the inner fixed wall of the positioning cylinder is provided with sleeves corresponding to the position of the lifting rod, and the inner side wall is provided with sleeves corresponding to the position of the push-pull rod. The inner ends of the push-pull rod and the lifting rod are provided with pistons, and the pistons slide in a sealed fit with the inner walls of the corresponding sleeves. Springs are provided on the push-pull rod and the lifting rod. One end of the spring is fixedly connected to the piston. The spring corresponding to the push-pull rod is fixedly connected to the inner side wall of the positioning cylinder, and the spring corresponding to the lifting rod is fixedly connected to the bottom wall of the drive cylinder.

[0009] Furthermore, a drive shaft is rotatably provided inside the drive cavity, a gear is fixedly provided on the drive shaft, a drive block is provided at the upper end of the lifting rod, a rack is provided on the side wall of the drive block, the rack meshes with the gear, the drive shaft is connected to the rotating shaft through belt drive, and the driving rod rotates 90° when it rises to the highest point.

[0010] Furthermore, a positioning seat and a rotating motor are provided on one side of the lifting frame. The output shaft of the rotating motor is fixedly connected to the positioning seat. The diameter of the positioning seat is larger than the diameter of the positioning cylinder and the commutator. The stacked commutators are placed on the positioning seat.

[0011] Furthermore, the positioning seat is equipped with multiple sets of lifting cylinders, and the bottom end of the positioning cylinder is fixedly connected to the free end of the lifting cylinder. The positioning cylinder is driven to rise and fall by the lifting cylinder, so that the distance between the upper surface of the positioning seat and the horizontal pressure plate is an integer multiple of the height of the commutator to be processed.

[0012] Furthermore, the lower surface of the positioning seat is provided with universal rollers. The universal rollers ensure the stability of the rotation of the positioning seat and the positioning cylinder on it driven by the rotating motor.

[0013] Furthermore, multiple sets of fixed support plates are evenly distributed along the circumference of the positioning cylinder, and the sleeves corresponding to each set of fixed support plates are staggered.

[0014] Furthermore, the fixed support plate includes a fixed plate and a movable plate. The fixed plate is fixed to the free end of the push-pull rod. The fixed plate has a T-shaped mounting groove in the vertical direction. The movable plate is snapped into and detachably installed in the mounting groove. The movable plate is available in various specifications. The side wall of the movable plate is an arc-shaped surface adapted to the inner curvature of the commutator. The side wall of the fixed plate has mounting screw holes communicating with the mounting groove. The movable plate has corresponding fixing screw holes and is fixedly connected by fixing bolts.

[0015] Furthermore, the lower end of the movable plate is provided with a sliding groove with a T-shaped cross-section, and an auxiliary support plate is slidably disposed in the sliding groove. The outer surface of the auxiliary support plate is arc-shaped with the outer surface of the movable plate. Under the action of gravity, the auxiliary support plate slides downward along the sliding groove and contacts the upper surface of the positioning seat.

[0016] Furthermore, the sleeve on the top wall of the positioning cylinder is a rotating structure, the driving cylinder is fixedly mounted on the top of the sleeve, a driven gear is fixedly mounted on the outer side of the sleeve, an adjusting motor is fixedly mounted on the inner top wall of the air chamber, and a driving gear is mounted on the output shaft of the adjusting motor, the driving gear meshing with the driven gear.

[0017] Furthermore, the positioning seat is equipped with an air pump, which is connected to the air chamber through an air pipe to regulate the air pressure in the air chamber.

[0018] The technical solution provided by this invention has the following beneficial effects: (1) Multiple sets of commutators are stacked with positioning cylinders and a lifting slotting mechanism are used to realize synchronous slotting of multiple sets of commutators without frequent machine stop for clamping; the pressure plate avoidance is driven by motor gear transmission, without the need to stop the machine for adjustment, further ensuring the continuity of processing and adapting to large-scale production.

[0019] (2) The air-driven radial support and axial compression, combined with the auxiliary support plate for positioning, effectively prevent workpiece displacement; the sealing design of the piston and sleeve ensures stable air pressure in the air chamber, improves positioning consistency, and reduces scrap rate.

[0025] See Figures 1-8In this embodiment, the present invention provides a commutator 2 side groove processing device, including a positioning cylinder 1, a push-pull rod 4, a drive cylinder 6, and a lifting rod 10. Multiple sets of commutators 2 are stacked on the outer side of the positioning cylinder 1, and a pressure-adjustable sealed air chamber 3 is opened inside the positioning cylinder 1. The push-pull rod 4 is slidably disposed on the side wall of the positioning cylinder 1 and moves axially driven by changes in air pressure within the air chamber 3. A fixed support plate 5 is provided at the free end of the push-pull rod 4. When the push-pull rod 4 slides outward, it drives the fixed support plate 5 to tighten and fix the commutator 2 from the inside. The drive cylinder 6 is disposed above the positioning cylinder 1, and a drive cavity 7 is opened inside the drive cylinder 6. A rotating shaft 8 is rotatably disposed on the top wall of the drive cylinder 6, and a fixed device is mounted on the rotating shaft 8. There is a pressure plate 9, which can switch between vertical and horizontal states as it rotates with the rotating shaft 8. In the initial state, the pressure plate 9 is in a vertical state, which facilitates the stacking of the commutator 2. In the horizontal state, it presses on the top of the stacked commutator 2 to ensure the stability of the grooving process. The lifting rod 10 is slidably disposed through the top wall of the positioning cylinder 1 and the bottom wall of the driving cylinder 6. The lower end extends into the air chamber 3 and the upper end extends into the driving chamber 7. It is driven to rise and fall by the air pressure change in the air chamber 3. When the lifting rod 10 rises and falls, it is linked to the rotating shaft 8 to rotate, which drives the pressure plate 9 to switch states.

[0026] Specifically, see Figure 1 and Figure 8 In this embodiment, a grooving mechanism is provided on one side of the positioning cylinder 1. The grooving mechanism includes a lifting frame 11, a lifting block 12, an electric telescopic rod 13, and a grooving cutter 14. The lifting block 12 is configured to be able to move up and down along the lifting frame 11. The electric telescopic rod 13 is located on the lifting block 12. The grooving cutter 14 is located at the free end of the electric telescopic rod 13. The electric telescopic rod 13 is used to install the grooving cutter 14 and adjust the horizontal position of the grooving cutter 14. It is suitable for commutators 2 of different diameters. It should be noted that the grooving cutter 14 adopts existing technology.

[0027] Specifically, see Figure 1 and Figure 8 In this embodiment, a lifting groove 15 is provided on the side wall of the lifting frame 11, a lifting motor 16 is provided on the lifting frame 11, a lifting screw 17 is rotatably provided inside the lifting frame 11, one end of the lifting screw 17 is connected to the output shaft of the lifting motor 16, a guide rod 18 is provided on the lifting frame 11, and a lifting block 12 is connected to the lifting screw 17 by a thread and slidably disposed on the guide rod 18. Both ends of the lifting block 12 are slidably disposed in the lifting groove 15. The lifting block 12 can be driven to rise and fall along the lifting frame 11 by the rotation drive of the lifting screw 17 and the guidance of the guide rod 18, so as to continuously slot the stacked commutator 2.

[0028] Specifically, see Figure 4 , Figure 6 and Figure 7In this embodiment, sleeves 19 are provided on the inner fixed wall of the positioning cylinder 1 corresponding to the position of the lifting rod 10 and on the inner side wall corresponding to the position of the push-pull rod 4. Pistons 20 are provided on the inner ends of the push-pull rod 4 and the lifting rod 10. The pistons 20 slide in a sealed fit with the inner wall of the corresponding sleeves 19 to ensure the air chamber 3 is sealed. Springs 21 are provided on the push-pull rod 4 and the lifting rod 10. One end of the spring 21 is fixedly connected to the piston 20. The spring 21 corresponding to the push-pull rod 4 is fixedly connected to the inner side wall of the positioning cylinder 1, and the spring 21 corresponding to the lifting rod 10 is fixedly connected to the bottom wall of the drive cylinder 6. When the air pressure in the air chamber 3 decreases, the elastic force of the spring 21 cooperates with the drive piston 20 to drive the push-pull rod 4 and the lifting rod 10 to reset.

[0029] Specifically, see Figure 4 and Figure 6 In this embodiment, a drive shaft 22 is rotatably mounted inside the drive cavity 7, and a gear 23 is fixedly mounted on the drive shaft 22. A drive block 24 is mounted on the upper end of the lifting rod 10, and a rack 25 is mounted on the side wall of the drive block 24. The rack 25 meshes with the gear 23. The drive shaft 22 is connected to the rotating shaft 8 via a belt drive. When the lifting rod 10 rises to its highest position, it drives the rotating shaft 8 to rotate 90°. Specifically, when the lifting rod 10 drives the drive block 24 to rise, the rack 25 drives the gear 23 to rotate the drive shaft 22 by 90°, which in turn drives the rotating shaft 8 to rotate by 90° via the belt, causing the pressure plate 9 to switch from a vertical state to a horizontal state. When the lifting rod 10 returns to its lower position, the gear 23 and rack 25 reverse their transmission, causing the pressure plate 9 to rotate back to a vertical state.

[0030] Specifically, see Figure 3 and Figure 5 In this embodiment, a positioning seat 26 and a rotating motor 27 are provided on one side of the lifting frame 11. The output shaft of the rotating motor 27 is fixedly connected to the positioning seat 26. The diameter of the positioning seat 26 is larger than the diameter of the positioning cylinder 1 and the commutator 2. The stacked commutator 2 is placed on the positioning seat 26.

[0031] Specifically, see Figure 5 In this embodiment, the positioning seat 26 is provided with multiple sets of lifting cylinders 28. The bottom end of the positioning cylinder 1 is fixedly connected to the free end of the lifting cylinder 28. The positioning cylinder 1 is driven to rise and fall by the lifting cylinder 28, so that the distance between the upper surface of the positioning seat 26 and the horizontal pressure plate 9 is an integer multiple of the height of the commutator 2 to be processed, ensuring that multiple sets of stacked commutators 2 can be pressed by the pressure plate 9.

[0032] Specifically, see Figure 3 and Figure 5 In this embodiment, the lower surface of the positioning seat 26 is provided with universal rollers 29. The universal rollers 29 ensure the stability of the rotation of the positioning seat 26 and the positioning cylinder 1 on it driven by the rotating motor 27.

[0033] Specifically, see Figure 3 and Figure 5 In this embodiment, multiple sets of fixed support plates 5 are evenly distributed along the circumference of the positioning cylinder 1, and the sleeves 19 corresponding to each set of fixed support plates 5 are staggered, which not only leaves enough space for the axial movement of the push-pull rod 4 to meet the fixed support requirements of different specifications of commutators 2, but also avoids mutual interference.

[0034] Specifically, see Figure 2 and Figure 7 In this embodiment, the fixed support plate 5 includes a fixed plate 30 and a movable plate 31. The fixed plate 30 is fixed to the free end of the push-pull rod 4. The fixed plate 30 has a T-shaped mounting groove 32 vertically. The movable plate 31 is snapped into and detachably installed in the mounting groove 32. The movable plate 31 has various specifications. The side wall of the movable plate 31 is an arc-shaped surface that matches the inner curvature of the commutator 2. It can be flexibly replaced according to the specifications of the commutator 2. The upper dimension of the movable plate 31 is larger than the dimension of the mounting groove 32. The dimensions of the other parts of the movable plate 31 are adapted to the dimensions of the mounting groove 32. The difference in dimensions allows the mounting groove 32 to limit the movable plate 31, making it easy to determine that the movable plate 31 is installed in place. The side wall of the fixed plate 30 has a mounting screw hole that communicates with the mounting groove 32. The movable plate 31 has a corresponding fixing screw hole and is fixedly connected by fixing bolts 33.

[0035] Specifically, see Figure 3 and Figure 5 In this embodiment, the lower end of the movable plate 31 is provided with a sliding groove 34 with a T-shaped cross-section. The outer surface of the sliding groove 34 penetrates the outer surface of the movable plate 31. An auxiliary support plate 35 is slidably provided in the sliding groove 34. The outer surface of the auxiliary support plate 35 is concentric with the outer surface of the movable plate 31, and the upper dimension of the auxiliary support plate 35 is larger than the dimension of the sliding groove 34. The dimensions of the remaining parts of the auxiliary support plate 35 are adapted to the sliding groove 34. The setting of this dimension difference prevents the auxiliary support plate 35 from completely sliding out of the sliding groove 34. When the lifting cylinder 28 drives the positioning cylinder 1 to rise, the auxiliary support plate 35 slides down along the sliding groove 34 under the action of gravity and contacts the upper surface of the positioning seat 26, which helps to tighten the lower commutator 2 and improves the overall positioning stability.

[0036] Specifically, see Figure 4 and Figure 6 In this embodiment, the sleeve 19 on the top wall of the positioning cylinder 1 is a rotating structure. The driving cylinder 6 is fixedly installed on the top of the sleeve 19. A driven gear 36 is fixedly installed on the outer side of the sleeve 19. An adjusting motor 37 is fixedly installed on the inner top wall of the air chamber 3. An active gear 38 is installed on the output shaft of the adjusting motor 37. The active gear 38 meshes with the driven gear 36. When the pressure plate 9 rotates with the positioning seat 26 to the slotted path, the adjusting motor 37 drives the active gear 38 to rotate. Through the meshing of the gear 23, the sleeve 19, the driving cylinder 6 and the pressure plate 9 rotate synchronously to achieve the position avoidance of the pressure plate 9.

[0037] It should be noted that the top wall of the positioning cylinder 1 is equipped with a sealed motor housing, and the top wall of the motor housing is equipped with a vent hole to communicate with the outside. The adjusting motor 37 is fixed inside the motor housing to prevent changes in air pressure in the air chamber 3 from affecting the service life of the adjusting motor 37.

[0038] Specifically, see Figure 3 and Figure 5 In this embodiment, the positioning seat 26 is equipped with an air pump 39, which is connected to the air chamber 3 through an air pipe and is used to adjust the air pressure in the air chamber 3. The air pump 39 can apply high pressure or low pressure to the air chamber 3.

[0039] The specific usage and operating methods of this equipment are as follows: (1) Workpiece fitting and clamping: According to the specifications of the commutator 2 to be processed, select the corresponding arc-shaped movable plate 31, and insert the movable plate 31 into the T-shaped mounting groove 32 of the fixed plate 30. The movable plate 31 is fixed by passing the mounting screw hole and the fixing screw hole through the fixing bolt 33. Multiple sets of commutators 2 are stacked and sleeved on the outside of the positioning cylinder 1 so that the lower end of the commutator 2 is placed on the positioning seat 26.

[0040] (2) Positioning height adjustment: Start the lifting cylinder 28 on the positioning seat 26 to drive the positioning cylinder 1 to rise and fall vertically, adjust the distance between the upper surface of the positioning seat 26 and the pressure plate 9 below the driving cylinder 6 so that the distance is equal to an integer multiple of the height of the commutator 2 to be processed, and ensure that all stacked commutators 2 can be covered and pressed by the pressure plate 9.

[0041] (3) Pneumatic positioning and fixing: Start the air pump 39 in the positioning seat 26 to apply high pressure to the air chamber 3 of the positioning cylinder 1. The air pressure pushes the piston 20 on the push rod 4 and the lifting rod 10 to slide along the sleeve 19. The push rod 4 extends outward and drives multiple sets of fixed support plates 5 to be synchronously tightened from the inside of the commutator 2 to achieve radial positioning. At the same time, the lifting rod 10 rises upward and meshes with the gear 23 on the drive shaft 22 through the rack 25 on the drive block 24, driving the drive shaft 22 to rotate 90°. Then, through the belt drive, the rotating shaft 8 rotates 90°, so that the pressure plate 9 switches from the vertical state to the horizontal state and presses on the top of the uppermost commutator 2 to achieve axial positioning. At this time, the auxiliary support plate 35 slides down along the sliding groove 34 of the movable plate 31 under the action of gravity, and the lower end contacts the upper surface of the positioning seat 26 to help tighten the lower commutator 2.

[0042] (4) Slotting position adjustment: Start the electric telescopic rod 13 and adjust the horizontal position of the slotting knife 14 so that the slotting knife 14 fits the preset slotting position on the side of the commutator 2; then start the lifting motor 16 of the slotting mechanism to drive the lifting screw 17 to rotate, and drive the lifting block 12 to rise and fall along the guide rod 18 and the lifting groove 15, and slot the multiple sets of commutators 2 stacked by the slotting knife 14.

[0043] (5) Synchronous grooving and circumferential adjustment: After the grooving of the commutator 2 is completed at the position directly below the grooving knife 14, the rotating motor 27 is started to drive the positioning seat 26, the positioning cylinder 1 and the stacked commutator 2 to slowly rotate at a fixed angle, so as to realize the continuous processing of multiple grooves in the circumferential direction of the side of the commutator 2.

[0044] (6) Pressure plate 9 avoids and continues to process: When the pressure plate 9 rotates with the commutator 2 to the processing path of the grooving cutter 14, the air pump 39 stops pressurizing and draws air from the air chamber 3 to reduce the pressure. The spring 21 drives the piston 20 to reset the push-pull rod 4 and the lifting rod 10. The push-pull rod 4 retracts and releases the commutator 2. The lifting rod 10 descends and drives the pressure plate 9 back to the vertical position. The adjusting motor 37 in the motor housing is started. Through the meshing of the driving gear 38 and the driven gear 36, the sleeve 19, the drive cylinder 6 and the pressure plate 9 are driven to rotate to a position that avoids the grooving path. Then the air pump 39 pressurizes the air chamber 3 again. The push-pull rod 4 and the pressure plate 9 are reset and repositioned to continue the grooving process.

[0045] (7) Processing completion and unloading: After all grooves are processed, the air pump 39 draws air to reduce the pressure in the air chamber 3, the positioning structure is reset, the pressure plate 9 rotates back to the vertical position, and the fixed support plate 5 retracts; all drive components are turned off, the stacked commutator 2 finished product is removed, and one processing cycle is completed.

[0046] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0047] The embodiments have been described above, and such description is not restrictive. The figures shown are only one embodiment, and the actual structure is not limited to this. In short, if a person skilled in the art is inspired by this description and designs a similar structure and embodiment without departing from the inventive spirit, such design should fall within the scope of protection.
