Description

Technical Field

[0001] This utility model relates to the field of retaining ring processing technology, specifically a grinding device for retaining ring processing. Background Technology

[0002] These are common fasteners in mechanical assembly. They are installed in shaft grooves or hole grooves to prevent axial displacement of related parts. Their main material is 65Mn spring steel. According to their shape, they can be divided into two categories: shaft-type and hole-type. Among them, C-type snap rings are widely used in the automotive, hardware, and electronics industries due to their versatility. The retaining ring grinding device is an automated or semi-automated equipment specifically used for surface treatment of retaining ring parts. It is mainly used to remove burrs, improve surface finish, and ensure dimensional accuracy. The existing grinding device for retaining ring processing first fixes the retaining ring to the upper end of the chuck when grinding the retaining ring. Then, multiple electric slide rails drive the grinding head to move in various directions. Next, the drive motor drives the grinding head to rotate at high speed to grind the retaining ring. After grinding, the worker opens the box door and uses a high-pressure air gun to blow and collect the debris inside the machine. Existing grinding devices for retaining ring processing have the following problems: when grinding the retaining ring, opening the chamber door to blow away and collect the grinding debris will cause some debris to fly out, polluting the working environment. At the same time, the machine needs to be stopped for cleaning, which will affect the grinding efficiency of the retaining ring. Therefore, we propose a grinding device for retaining ring processing.

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.

[0015] Please see Figure 1-4This embodiment provides a technical solution: a grinding device for processing retaining rings, including a machine base 1. A polishing machine 2 is provided at the upper end of the machine base 1. (The polishing machine 2 is a prior art four-axis grinding machine. The four-axis grinding machine includes an electric slide rail one, a support frame, an electric slide rail two, a support plate, an electric push rod, a mounting frame, a drive motor, and a grinding head. The electric slide rail one is located on the left and right sides of the upper end of the machine base 1. A support frame is provided between the sliding blocks one of the two electric slide rails one. An electric slide rail two is provided between the upper ends of the support frame. A support plate is provided on the front side of the sliding block two at the front end of the electric slide rail two. An electric push rod is provided at the upper end of the support plate. A mounting frame is fixedly connected to the telescopic end of the electric push rod. A drive motor is provided on the bottom wall of the mounting frame. A grinding head is fixedly connected to the lower end of the output shaft of the drive motor.) The input ends of the electric slide rail, electric push rod, and drive motor are all electrically connected to the output end of the microcontroller 11. By controlling the microcontroller 11, the electric slide rail operates, and the electric slide rail moves the support frame back and forth via the sliding block 1. The electric slide rail moves the support plate left and right via the sliding block 2. The telescopic end of the electric push rod moves the drive motor and grinding head up and down via the mounting bracket, thereby adjusting the position of the grinding head. The output shaft of the drive motor rotates the grinding head to grind the retaining ring. A three-jaw chuck 3 is located in the middle of the upper part of the machine base 1. (The three-jaw chuck 3 is a conventional three-jaw chuck, including a chuck body, jaws, spiral groove, large bevel gear, small bevel gear, and adjusting wrench. Rotating the adjusting wrench drives the small bevel gear to rotate, and the rotation of the small bevel gear...) The rotating bevel gear causes the chuck to move towards the center of the spiral groove on the right side of the bevel gear, thus clamping the retaining ring. A protective box 4 is located at the upper edge of the machine base 1, which also includes a debris cleaning mechanism 9. A microcontroller 11 is located at the left end of the machine base 1. The input of the microcontroller 11 is electrically connected to an external power source, and the input of the polishing machine 2 is electrically connected to the output of the microcontroller 11. A strip-shaped channel 10 is located at the front end of the machine base 1, with a baffle 6 at the upper front edge of the strip-shaped channel 10. A debris collection box 7 is located on the lower side of the machine base 1, with the lower end of the strip-shaped channel 10 corresponding to the upper end of the debris collection box 7. (Exhaust holes are located at both ends of the machine base 1, and evenly spaced exhaust vents are located on both sides of the debris collection box 7.) The filter holes of the cloth are designed so that when the debris collection box 7 is inserted into the machine base 1, the feed inlet on the upper side of the debris collection box 7 corresponds to the lower end of the strip channel 10. A rubber sealing ring can be provided at the edge of the feed inlet on the upper side of the debris collection box 7. The height of the debris collection box 7 is the same as the height of the bottom inner wall of the machine base 1. When the debris collection box 7 is inserted into the bottom of the machine base 1, the feed inlet on the upper side of the debris collection box 7 is aligned with and connected to the lower end of the strip channel 10. At the same time, the rubber sealing ring compresses and presses the top wall of the bottom of the machine base 1 to ensure the sealing of the connection. When gas and debris enter the strip channel 10, the gas and debris will enter the interior of the debris collection box 7. The gas will be discharged through the filter holes on both sides of the debris collection box 7, and the debris will be blocked by the filter holes inside the debris collection box 7.Excess gas will be discharged through the exhaust ports at both ends of machine 1. A sealing door 8 is hinged to the front of machine 1. (A door lock is installed between the sealing door 8 and the front of machine 1. The door lock uses a rotary latch lock structure commonly used in existing technology. The rotary latch lock is a mechanical device that achieves locking function through a rotating cam structure. Its core consists of a lock cylinder, a latch, a base, and other components. A sealing ring can be installed at the edge of the sealing door 8 to ensure that sealing debris does not leak out after the sealing door 8 is closed.) Symmetrical doors 5 are hinged to the front of protective box 4. (Observation windows are provided at both ends of protective box 4.) (A door lock is installed between the inner ends of the doors 5. The door lock uses a surface-mounted bolt lock structure commonly used in existing technology. The surface-mounted bolt lock consists of a bolt (with a beveled or conical head), a latch, and a spring. When the door is closed, the bolt is automatically retracted by impact, and the spring drives it back.) The spring is inserted into the locking slot to achieve locking. A sealing ring can be set at the edge of the door 5 to ensure that the sealing debris does not leak out after the door 5 is closed. When grinding the retaining ring, the door 5 is opened first. After the retaining ring is placed on the three-jaw chuck 3, the three-jaw chuck 3 achieves centering clamping through radial synchronous extension and retraction to prevent the retaining ring from shifting or becoming eccentric during grinding. Then, after closing the door 5 of the protective box 4, the polishing machine 2 is operated by the control of the microcontroller 11, so that the contact area between the polishing machine 2 and the retaining ring is evenly stressed along the circumference to achieve the processing purpose of deburring and improving the surface finish. The debris blown off by the high-speed airflow is guided by the baffle 6 and falls into the strip channel 10 at the front of the machine base 1, and slides down the strip channel 10 into the debris collection box 7 on the lower side of the machine base 1. After processing, the debris in the debris collection box 7 can be collected and cleaned by opening the sealing door 8 at the front of the machine base 1. Debris cleaning mechanism 9: It includes a protective cover 91, a sliding plate 92, a rotating frame 93, an adjusting block 94, an air pipe 95, and a nozzle 96. The protective cover 91 is located at the rear end of the protective box 4. The sliding plate 92 is slidably connected between the left and right inner walls of the protective cover 91. The bottom wall of the middle part of the sliding plate 92 is rotatably connected to the rotating frame 93 through a rotating column. The adjusting block 94 is rotatably connected between the left and right inner walls of the rotating frame 93 through a rotating shaft. The air pipe 95 is located in the middle of the adjusting block 94, and the nozzle 96 is located at the front end of the air pipe 95. The debris cleaning mechanism 9 also includes a sliding block 97 and a clearance hole 98. The clearance hole 98 is opened in the middle of the rear end of the protective cover 91. The sliding block 97 is located in the middle of the rear end of the sliding plate 92. The outer wall of the sliding block 97 is slidably connected to the inner wall of the clearance hole 98. (It can be...) Rubber strips are fixedly connected between the upper end of the sliding block 97 and the top wall of the clearance hole 98, and between the bottom wall of the clearance hole 98 and the lower end of the sliding block 97, to prevent debris from flying out of the protective box 4). The lower end of the sliding block 97 is fixedly connected to the outer wall of the rear end of the air pipe 95. The debris cleaning mechanism 9 also includes a drive assembly 99, which includes a second motor 994 and a third motor 995. The second motor 994 is located in the middle of the upper end of the sliding plate 92. The lower end of the output shaft of the second motor 994 is fixedly connected to the upper end of the rotating column. The third motor 995 is located at the left end of the rotating frame 93. The right end of the output shaft of the third motor 995 is fixedly connected to the left end of the rotating shaft. The input ends of the second motor 994 and the third motor 995 are both electrically connected to the output end of the microcontroller 11. The drive assembly 99 also includes a motor. 991, threaded rod 992, and guide rod 993. Guide rod 993 is fixedly connected to the left side between the upper and lower inner walls of protective cover 91. Threaded rod 992 is rotatably connected to the right side between the upper and lower inner walls of protective cover 91. The sliding hole on the left side of sliding plate 92 is slidably connected to guide rod 993, and the threaded hole on the right side of guide rod 993 is threadedly connected to threaded rod 992. (Corrugated pipes are fixedly connected between the top wall of protective cover 91 and the upper end of sliding plate 92, and between the lower end of sliding plate 92 and the bottom wall of protective cover 91. The corrugated pipes are respectively sleeved on the outside of threaded rod 992 to protect threaded rod 992, prevent debris from entering the interior of threaded rod 992, ensure the sealing and lubrication of threaded rod 992, and extend service life.) The upper right side of protective cover 91 is equipped with... There is a motor 991, the lower end of which is fixedly connected to the upper end of the threaded rod 992. The input end of the motor 991 is electrically connected to the output end of the microcontroller 11. During the grinding process, the air pipe 95 is connected to an external air compressor in advance. By controlling the microcontroller 11, the air compressor operates and transmits the high-pressure air generated by the air compressor to the nozzle 96 at the front end through the air pipe 95. The high-speed airflow is sprayed out through the air pipe 95 and blown towards the debris in the grinding area. Then, by controlling the microcontroller 11, the motor 991 operates, and the output shaft of the motor 991 drives the threaded rod 992 to rotate. The sliding plate 92 is slidably connected to the guide rod 993 on the left side and threadedly connected to the threaded rod 992 on the right side. The sliding plate 92 slides up and down along the guide rod 993.This causes the nozzle 96 to move up and down, achieving vertical adjustment. Then, motor 2 994 operates, its output shaft driving the rotating frame 93 to rotate via a rotating column, causing the nozzle 96 to rotate horizontally around the column, achieving horizontal adjustment. Next, motor 3 995 operates, its output shaft driving the adjusting block 94 to rotate via a rotating shaft, causing the nozzle 96 to tilt around the rotating shaft, achieving tilt angle adjustment. The sliding block 97 at the rear end of the sliding plate 92 slides within the clearance hole 98 of the protective cover 91, moving up and down synchronously with the sliding plate 92 while also fixing the position of the air pipe 95, preventing it from becoming tangled or interfering with other components. Finally, the desired spray angle can be adjusted through the observation window.

[0016] The working principle of the grinding device for retaining ring processing provided by this utility model is as follows: When grinding the retaining ring, the door 5 is first opened, and the retaining ring is placed on the three-jaw chuck 3. The three-jaw chuck 3 achieves centering clamping through radial synchronous extension and retraction, preventing the retaining ring from shifting or becoming eccentric during grinding. Then, after closing the door 5 of the protective box 4, the polishing machine 2 is operated under the control of the microcontroller 11, so that the contact area between the polishing machine 2 and the retaining ring is evenly stressed along the circumference, achieving the processing purpose of deburring and improving the surface finish. During the grinding process... In the process, the air pipe 95 is connected to an external air compressor in advance. Through the control of the microcontroller 11, the air compressor operates, and the high-pressure air generated by the air compressor is transmitted through the air pipe 95 to the nozzle 96 at the front end. A high-speed airflow is then ejected through the air pipe 95, blowing towards the debris in the grinding area. Then, through the control of the microcontroller 11, the motor 991 operates. The output shaft of the motor 991 drives the threaded rod 992 to rotate. The sliding plate 92 is slidably connected to the guide rod 993 on the left side and threadedly connected to the threaded rod 992 on the right side. The movable plate 92 slides up and down along the guide rod 993, thereby driving the nozzle 96 to move up and down, achieving vertical adjustment. Then, the second motor 994 operates, and the output shaft of the second motor 994 drives the rotating frame 93 to rotate through the rotating column, causing the nozzle 96 to rotate horizontally around the rotating column, achieving horizontal adjustment. Then, the third motor 995 operates, and the output shaft of the third motor 995 drives the adjusting block 94 to rotate through the rotating shaft, causing the nozzle 96 to tilt around the rotating shaft, achieving tilt angle adjustment. The sliding block 97 at the rear end of the sliding plate 92 is in the protective cover 91. The air pipe 95 slides within the clearance hole 98, moving up and down synchronously with the sliding plate 92, while also fixing the position of the air pipe 95 to prevent it from getting tangled or interfering with other components. The required blowing angle can then be adjusted through the observation window. The debris blown off by the high-speed airflow is guided by the baffle 6 and falls into the strip channel 10 at the front of the machine 1, then slides down the strip channel 10 into the debris collection box 7 on the lower side of the machine 1. After processing, the debris in the debris collection box 7 can be cleaned by opening the sealing door 8 at the front of the machine 1.

[0017] It is worth noting that, in the above embodiments, the polishing machine 2, motor 1 991, motor 2 994, and motor 3 995 can all be selected from the following: polishing machine 2 can be HPD-43-4A5027-2, motor 1 991 can be D180M-0160030B-E, and motor 2 994 and motor 3 995 can both be YS8024.
