Description

Technical Field

[0001] The invention relates to the technical field of commutator copper sheets, and more particularly to a frosted surface commutator copper sheet processing device and method. Background Art

[0002] In the field of modern automobile industry, the performance of the motor system of large vehicles and off-road vehicles is directly related to the power output and reliability of the vehicle. Among them, the surface treatment of the motor commutator copper sheet is a key process link. Since these vehicles often operate in complex environments and need to cope with various harsh working conditions, their motor commutator copper sheets must have a specific surface roughness. In order to meet this technical requirement, a special rough grinding belt is required during the production process to accurately grind the copper sheet surface. This special surface treatment can not only improve the conductivity of the commutator, but also significantly extend the service life of the motor, which is of great significance to the performance improvement of the whole vehicle.

[0003] However, the grinding equipment currently on the market has obvious technical defects in the installation of commutator copper sheets. First, the clamping mechanism design of the existing equipment is not convenient enough, and operators need to perform cumbersome positioning and adjustments when installing the copper sheets; secondly, the equipment lacks the ability to quickly locate and disassemble, resulting in each installation taking time to install and adjust. These problems not only reduce production efficiency, but also increase the labor intensity of workers, and are also prone to cause deviations in processing accuracy. Summary of the invention

[0008] The mounting mechanism comprises a transmission shaft rotatably connected to the slider and an inner sleeve fixedly mounted in the transmission shaft, a fixing rod coaxially arranged with the inner sleeve is slidably arranged in the inner sleeve, two gradient sleeves are mounted on the fixing rod, when the fixing rod is in a fixed state, a plurality of one-way blocks are attached to the fixing rod, the one-way blocks in the same plane are respectively pressed on the gradient sleeves, and a follower block is respectively mounted on each two of the one-way blocks; and

[0009] The positioning mechanism includes a transverse hole opened in the follower block, an extension rod is slidably installed in the transverse hole, and the side wall of the inner sleeve is provided with fixing holes with the same number as the extension rod. The diameter of the fixing holes is larger than the diameter of the transverse holes. When the one-way block rotates at high speed with the transmission shaft, the extension rod will be inserted into the fixing holes.

[0010] Preferably, the positioning mechanism also includes a return spring installed on the side of the extending rod away from the fixing hole, and there are multiple return springs, and the multiple return springs are respectively connected in the transverse holes, and a round head is installed on the extending rod close to the fixing hole.

[0011] Preferably, the installation mechanism also includes a contraction groove opened along the axis of the inner sleeve, and a plurality of the contraction grooves are arranged at equal intervals, and each of the contraction grooves is slidably connected to the follower block, and a push spring is installed on the lower end surface of each follower block, and the plurality of push springs respectively abut against the lower end surface of the inner sleeve.

[0012] Preferably, a plurality of telescopic rods are slidably mounted on the upper end surface of the inner sleeve, and each of the telescopic rods corresponds to one of the follower blocks, a receiving spring is mounted on the upper end surface of the follower block, and the receiving spring is connected to the telescopic rod.

[0013] Preferably, the plurality of telescopic rods are provided with inner nests coaxial with the inner sleeve, and the inner nests are provided with the same number of embedding grooves as the telescopic rods.

[0014] Preferably, a pressure rod is coaxially mounted on the fixing rod, a plurality of outward expansion rods are evenly spacedly mounted on the side wall of the pressure rod, the plurality of outward expansion rods are respectively slidably connected in the embedding groove, and a compression spring is respectively mounted on each of the outward expansion rods.

[0015] Preferably, a spline is installed on the outer wall of the transmission shaft, and a fixed sleeve is installed on the transmission shaft, a plurality of key slots are opened on the inner wall of the fixed sleeve, the splines are stuck in the key slots, and the plurality of compression springs are respectively pressed on the outer wall of the fixed sleeve, and a plurality of copper sheet bodies are installed on the outer wall of the fixed sleeve at equal intervals.

[0016] Preferably, a motor is fixedly mounted on the fixed frame, a driving wheel is coaxially mounted on the protruding end of the motor, two driven wheels are rotatably arranged on the fixed frame, the driving wheel is meshed with the two driven wheels, a universal sleeve is respectively mounted on each of the driven wheels, the other end of the universal sleeve is connected to the transmission shaft, two hydraulic cylinders are mounted on the fixed frame, and the protruding ends of the hydraulic cylinders are connected to the slider.

[0017] Preferably, a grinding frame is installed on the fixed frame, a grinding belt is rotatably connected to the grinding frame, and a plurality of the copper sheet bodies are attached to the grinding belt.

[0018] The present invention provides a method for processing a frosted surface commutator copper sheet, comprising the following steps:

[0019] Step 1 is the installation process of the copper sheet. First, the fixed sleeve and the transmission shaft are slidably connected, and the torque is transmitted through the clamping connection of the spline and the keyway. Then the fixed rod is inserted into the fixed sleeve so that the outer expansion rod and the embedded groove form a sliding fit. When the fixed rod supports the follower block and the one-way block, the thrust of the pressure rod drives the follower block to slide in the contraction groove until the gradient sleeve and the one-way block form a stable locking state.

[0020] Step 2 is the grinding process. The hydraulic cylinder is started to drive the slider to slide along the fixed frame so that the copper sheet is fully in contact with the grinding belt. Then the motor is started to drive the driven wheel to rotate through the driving wheel, and then the rotation is transmitted to the transmission shaft through the universal sleeve, so that the copper sheet rotates in the opposite direction to the grinding belt. This reverse motion design can ensure that the surface of the copper sheet is evenly and effectively polished.

[0021] Step three is the disassembly process. When the processing is completed, the operator needs to press the pressure rod and the inner nest downward at the same time to make the follower block slide downward along the shrinkage groove and expand, thereby releasing the fixation between the one-way block and the gradient sleeve. While keeping the position of the inner nest unchanged, pull the pressure rod upward to remove the fixing rod, and finally release the inner nest to complete the entire disassembly process. This design makes the disassembly operation simple and intuitive, greatly improving work efficiency.

[0022] (III) Beneficial effects

[0023] Compared with the prior art, the present invention provides a frosted surface commutator copper sheet processing device and method, which has the following beneficial effects:

[0024] First of all, in terms of installation structure, the equipment adopts an innovative fixing mechanism design. Through the connection of splines and keyways, combined with the one-way clamping of the one-way block and the gradient sleeve, the rapid positioning of the copper sheet is achieved. The coordination of the gradient sleeve and the one-way block, plus the design of the follower block, not only simplifies the installation process, but also ensures the stability and reliability of the copper sheet installation. This design improves the installation efficiency of the commutator copper sheet and solves the problem of cumbersome installation of traditional equipment.

[0025] Secondly, in terms of the power transmission system, the smooth transmission of power is achieved through the meshing transmission of the motor, the driving wheel and the driven wheel, combined with the flexible connection of the universal sleeve. The design of the hydraulic cylinder ensures the control of the slider, making the contact between the copper sheet and the grinding belt more precise. This transmission method not only improves the processing efficiency, but also ensures the stability of the grinding process.

[0026] Finally, in terms of the positioning system, through the clever coordination of the transverse hole and the fixed hole, combined with the centrifugal force of the extension rod, the automatic positioning function during high-speed operation is realized. The design of the return spring ensures automatic resetting after shutdown. This positioning method not only improves the processing accuracy, but also enhances the safety of the equipment.

A motor 41 is fixedly installed, and a driving wheel 42 is coaxially installed on the extended end of the motor 41. Two driven wheels 43 are rotatably provided on the fixed frame 11. The driving wheel 42 is meshed with the two driven wheels 43. A universal sleeve 44 is installed on each driven wheel 43. The other end of the universal sleeve 44 is connected to the transmission shaft 21. Two hydraulic cylinders 45 are installed on the fixed frame 11. The extended end of the hydraulic cylinder 45 is connected to the slider 12. A grinding frame 46 is installed on the fixed frame 11. A grinding belt 47 is rotatably connected to the grinding frame 46. A plurality of copper sheet bodies 219 are attached to the grinding belt 47. The installation mechanism also includes a contraction opening along the axis of the inner sleeve 22. The inner sleeve 22 is provided with a plurality of contraction grooves 27 at equal intervals, and each contraction groove 27 is respectively slidably connected to a follower block 26, and a push spring 28 is installed on the lower end surface of each follower block 26, and the plurality of push springs 28 are respectively in contact with the lower end surface of the inner sleeve 22, and the upper end surface of the inner sleeve 22 is slidably installed with a plurality of telescopic rods 29, and each telescopic rod 29 corresponds to a follower block 26, and a receiving spring 210 is installed on the upper end surface of the follower block 26, and the receiving spring 210 is connected to the telescopic rod 29, and the plurality of telescopic rods 29 are provided with an inner nesting 211 coaxial with the inner sleeve 22, and the inner nesting 211 is provided with the same number of inserts as the telescopic rod 29. The drive shaft 21 is inserted into the groove 212, and a pressure rod 213 is coaxially installed on the fixed rod 23. A plurality of outward expansion rods 214 are evenly spaced on the side walls of the pressure rod 213. The plurality of outward expansion rods 214 are respectively slidably connected in the embedded groove 212, and a compression spring 215 is respectively installed on each outward expansion rod 214. A spline 216 is installed on the outer wall of the transmission shaft 21, and a fixed sleeve 217 is sleeved and installed on the transmission shaft 21. A plurality of key grooves 218 are opened on the inner wall of the fixed sleeve 217, and the spline 216 is stuck in the key groove 218. A plurality of compression springs 215 are respectively pressed on the outer wall of the fixed sleeve 217, and a plurality of copper sheet bodies 219 are evenly spaced on the outer wall of the fixed sleeve 217.

[0040] When the copper sheet body 219 is polished, since the multiple copper sheet bodies 219 are respectively installed on the fixed sleeve 217, the fixed sleeve 217 and the transmission shaft 21 are first fixed. After the installation is completed, the hydraulic cylinders 45 on the upper and lower sides are started to drive the slider 12 to slide along the fixed frame 11 so that the multiple copper sheet bodies 219 are attached to the corresponding polishing belt 47. Due to the action of the universal sleeve 44, the driven wheel 43 and the transmission shaft 21 can be connected in multiple directions. The surface of the copper sheet body 219 can be polished by the rotation of the polishing belt 47, and then the starting motor 41 can drive the driving wheel 42 to rotate, and then the two driven wheels 43 and the driven wheel 43 rotate accordingly, and then the transmission shaft 21 and the multiple copper sheet bodies 219 are driven to rotate through the two universal sleeves 44, and the rotation direction of the transmission shaft 21 is opposite to the rotation direction of the polishing belt 47. Therefore, the surfaces of the multiple copper sheet bodies 219 can be polished by the rough polishing belt 47, thereby completing the rough polishing process.

[0041] When fixing the multiple copper sheet bodies 219, firstly, the fixing sleeve 217 is slidably connected to the transmission shaft 21, and the spline 216 is stuck in the keyway 218, and the fixing sleeve 217 is made to contact the transmission shaft 21, and the torque can be transmitted through the clamping of the spline 216 and the keyway 218, and then the axial position of the fixing sleeve 217 needs to be limited. Since the inner sleeve 22 is fixedly installed in the transmission shaft 21, firstly, the fixing rod 23 is inserted into the fixing sleeve 217, and the multiple outward expansion rods 214 are slidably connected in the embedding groove 212. When the fixing rod 23 is pressed against the follower block 26 and the one-way block 25, the thrust of the pressure rod 213 will drive the multiple follower blocks 26 to move along the contraction groove 27. The sliding movement causes the multiple follower blocks 26 to expand while sliding downward, and the multiple push springs 28 are also in the process of compression. When the gradient sleeve 24 passes through the one-way block 25 and the one-way block 25 abuts against the side wall of the fixed rod 23, the extension rod 32 and the fixing hole 33 are in a coaxial state. At this time, the one-way block 25 not only presses on the side wall of the fixed rod 23, but also presses on the gradient sleeve 24. At this time, the fixed rod 23 is in a fixed state in the upward direction. At the same time, the compression springs 215 on the multiple outward expansion rods 214 are respectively pressed on the fixed sleeve 217. The multiple compression springs 215 will apply corresponding fixing force to the fixed sleeve 217, thereby ensuring axial stability and the whole is in a fixed state.

[0042] When it is necessary to unlock, the lock is in a stopped state. The operator holds the pressure rod 213 with one hand and the multiple inner nests 211 with the other hand, and exerts force downward at the same time. Then the telescopic rod 29 will slide downward and push the follower block 26 to slide downward synchronously through the receiving spring 210. When sliding downward, the follower block 26 will expand along the contraction groove 27, thereby unlocking the fixation between the one-way block 25 and the gradient sleeve 24. At this time, the inner nest 211 should not move, and the pressure rod 213 is pulled upward to pull out the fixing rod 23, and then the inner nest 211 is released to complete the unlocking process. The unlocking process is simply described as: pressing the rod 213 and the inner nest 211 at the same time, after unlocking, first pull the pressure rod 213 upward, and then release the inner nest 211 to unlock the connection.

[0043] See also Figure 7 to Figure 8 The positioning mechanism includes a transverse hole 31 provided in the follower block 26, a protruding rod 32 is slidably installed in the transverse hole 31, and the side wall of the inner sleeve 22 is provided with the same number of fixing holes 33 as the protruding rod 32, and the diameter of the fixing hole 33 is larger than the diameter of the transverse hole 31. When the one-way block 25 rotates at a high speed along with the transmission shaft 21, the protruding rod 32 will be inserted into the fixing hole 33. The positioning mechanism also includes a return spring 34 installed on the side of the protruding rod 32 away from the fixing hole 33, and a plurality of return springs 34 are provided, and the plurality of return springs 34 are respectively connected in the transverse hole 31, and a round head 35 is installed on the protruding rod 32 on the side close to the fixing hole 33.

[0044] When the transmission shaft 21 is in high-speed rotation, since the inner sleeve 22 will rotate accordingly, the extension rods 32 in the multiple follower blocks 26 will also rotate at high speed, and the transverse hole 31 and the fixed hole 33 are in a coaxial state. Under the action of strong centrifugal force, the multiple extension rods 32 will expand outward. Since the diameter of the return spring 34 is very small and only plays a return role, it will not limit the expansion of the telescopic rod 29. Since the diameter of the fixed hole 33 is larger than the transverse hole 31 and the extension rod 32, the telescopic rod 29 can be inserted into the fixed hole 33, thereby forming a second fixation. When rotating, the follower block 26 will be doubly fixed, thereby ensuring the stability of grinding. When the grinding stops, the telescopic rod 29 will be pulled back into the transverse hole 31 under the action of the return spring 34, so the connection can be released after stopping.

[0045] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
