Description

Technical Field

[0001] This application relates to the field of spring processing technology, and in particular to a device for processing the end face of a shock-absorbing spring. Background Technology

[0002] The published patent document CN219465665U discloses a spring end face processing device, including a fixed base. Support plates are symmetrically mounted on the left and right sides of the upper end of the fixed base. A sliding plate is slidably connected to the middle of the fixed base. A first rack seat and a second rack seat are movably inserted into the left and right ends of the sliding plate, respectively. A first gear meshes between the first rack seat and the second rack seat. The first gear is rotatably connected to the fixed base via a rotating shaft and is driven by a lower motor. An upper rack is fixedly mounted on the upper end of the sliding plate. An upper motor is fixedly mounted at the rear middle of the fixed base. A second gear is fixedly mounted on the output shaft of the upper motor, meshing with the upper rack. Limiting wheels are provided on both the front and rear sides of the sliding plate. This application allows for automatic grinding of the other end after grinding one end of the spring. The entire operation can be performed continuously with a high degree of automation. Furthermore, the use of blocking and pushing can further improve the grinding effect of the spring.

[0003] In practical use, the above devices grind one end of the spring before grinding the other end, resulting in low operating efficiency. Therefore, this application provides a device for processing the end face of a shock-absorbing spring. Utility Model Content

[0004] In view of the shortcomings of the prior art, this application provides a device for processing the end face of a shock-absorbing spring, which overcomes the shortcomings of the prior art and aims to solve the problems in the prior art.

[0005] To achieve the above objectives, this application provides the following technical solution: a shock-absorbing spring end face processing device, comprising a bracket, a spring support frame fixedly installed at the top of the bracket, a spring body placed on the top of the spring support frame, an L-shaped fixing frame fixedly installed at the bottom of the bracket, an adjustment mechanism provided above the L-shaped fixing frame, the adjustment mechanism comprising a dual-head motor, the dual-head motor fixedly installed at the top of the L-shaped fixing frame, screws fixedly installed at both output ends of the dual-head motor, two sets of rotating seats fixedly installed at the bottom of the bracket, the ends of the two sets of screws away from the dual-head motor being rotatably connected to the rotating seats, the screws... The outer surface is threaded with a movable block. The top of the bracket has two sets of adjustment slots. A rectangular frame is fixedly installed on the top of the movable block. A grinding mechanism is installed on the top of the rectangular frame through the adjustment slot. The grinding mechanism includes a motor. An inverted L-shaped fixing frame is fixedly installed on the opposite sides of the two sets of rectangular frames. A rotating shaft is fixedly installed on the output end of the motor. A grinding head is fixedly installed on one end of the rotating shaft through the inverted L-shaped fixing frame. A sensor is fixedly installed on the top of the spring support. A controller is fixedly installed on one side of the bracket and is signal-connected to the sensor. The controller is electrically connected to the control end of the dual-head motor.

[0006] By adopting the above technical solution, the spring body to be polished is placed on top of the spring support frame. A dual-head motor drives two sets of screws to rotate, bringing the two sets of moving blocks closer together until the two sets of polishing heads contact the two end faces of the spring body. Then, the two sets of motors are turned on to drive the two sets of rotating shafts to rotate. The rotating shafts, in conjunction with the polishing heads, polish the two ends of the spring body. At the same time, the position and size of the spring body are detected by sensors, and the signals are transmitted to the controller. When the sensors detect that the spring body is not in contact with the polishing heads, the controller controls the dual-head motors to start again until the sensors detect that the spring body is in contact with the polishing heads. The controller then controls the dual-head motors to stop running. This ensures both the polishing effect on the end faces of the spring body and improves the polishing efficiency.

[0007] As a preferred technical solution of this application, a limit block is fixedly installed at the end of each of the two sets of screws near the dual-head motor.

[0008] By adopting the above technical solution, the position of the moving block is restricted by the limiting block, which prevents the moving block from falling off the screw surface and improves its practicality during use.

[0009] As a preferred technical solution of this application, a guide rod is fixedly installed at the bottom of the bracket directly below the screw, and two sets of guide blocks are slidably connected to the outer surface of the guide rod. The two sets of guide blocks are respectively fixedly connected to the two sets of moving blocks by connecting blocks.

[0010] By adopting the above technical solution, the two sets of moving blocks drive the two sets of connecting blocks and guide blocks to move when they move. The two sets of guide blocks slide along the surface of the connecting blocks, which guides the moving blocks and improves the stability of the moving blocks when they move.

[0011] As a preferred technical solution of this application, the top of the bracket is provided with clamping mechanisms on both sides of the spring body. The clamping mechanism includes two sets of fixing frames, which are respectively fixedly installed on the side wall of the bracket. An electric push rod is fixedly installed on the top of the fixing frame, and a clamping block is fixedly installed on the telescopic end of the electric push rod.

[0012] By adopting the above technical solution, the spring body is clamped by moving two sets of clamping blocks through the extension and retraction of two sets of electric push rods, which improves the stability of the spring body during the processing and helps to improve the processing accuracy of the spring body.

[0013] As a preferred technical solution of this application, anti-slip pads are fixedly installed on the top of both sets of clamping blocks.

[0014] By adopting the above technical solution, the friction between the clamping block and the spring body is increased by the anti-slip pad, which prevents the spring body from sliding during processing and improves the stability of the spring body during processing.

[0015] As a preferred technical solution of this application, the top of the bracket is fixedly installed with an isolation cover on the outer periphery of the two sets of grinding mechanisms. The side wall of the isolation cover is slidably connected with two sets of cover doors, and the interior of the two sets of cover doors is provided with grooves that match the clamping mechanism.

[0016] By adopting the above technical solution, the dust generated during the grinding process of the spring body is blocked by the cover, which helps to prevent a large amount of dust from entering the working environment and helps to maintain the cleanliness of the working environment.

[0017] As a preferred embodiment of this application, the thread directions of the two sets of screws are opposite.

[0018] By adopting the above technical solution, and by using two sets of screws with opposite directions, when the dual-head motor drives the two sets of screws to rotate in the forward or reverse direction, it is beneficial for the two sets of rotating seats to move closer or further apart synchronously.

[0019] As a preferred technical solution of this application, observation windows are fixedly installed on the front surface of both sets of doors.

[0020] By adopting the above technical solution, the observation window facilitates the observation of the spring body's processing, thus improving its practicality during use.

[0021] The beneficial effects of this application are:

[0022] 1. By placing the spring body to be polished on top of the spring support frame, the two sets of moving blocks are brought closer together by the dual-head motor driving two sets of screws until the two sets of polishing heads contact the two end faces of the spring body. Then, the two sets of motors are turned on to drive the two sets of rotating shafts to rotate. The rotating shafts are linked with the polishing heads to polish the two ends of the spring body. At the same time, the position and size of the spring body are detected by the sensor and the signal is transmitted to the controller. When the sensor detects that the spring body is not in contact with the polishing head, the controller controls the dual-head motor to start again until the sensor detects that the spring body is in contact with the polishing head. The controller then controls the dual-head motor to stop running. This ensures both the polishing effect on the end face of the spring body and improves the polishing efficiency.

[0023] 2. The position of the moving block is restricted by the limiting block to prevent the moving block from falling off the screw surface, thus improving its practicality during use. Attached Figure Description

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4 A shock-absorbing spring end face processing device includes a bracket 1, a spring support frame 2 fixedly installed at the top of the bracket 1, a spring body 3 placed on the top of the spring support frame 2, an L-shaped fixing frame 4 fixedly installed at the bottom of the bracket 1, an adjustment mechanism 5 arranged above the L-shaped fixing frame 4, the adjustment mechanism 5 including a double-head motor 501, the double-head motor 501 fixedly installed at the top of the L-shaped fixing frame 4, and screws 502 fixedly installed at both output ends of the double-head motor 501. Two sets of rotating seats 503 are fixedly installed at the bottom of the bracket 1, and the ends of the two sets of screws 502 away from the double-head motor 501 are rotatably connected to the rotating seats 503. Moving blocks 504 are threadedly connected to the outer surface of the screws 502. Two sets of adjustment grooves 505 are opened at the top of the bracket 1, and a rectangular frame 506 is fixedly installed at the top of the moving block 504. A grinding mechanism 6 is provided at the top of the frame 506 through an adjustment groove 505. The grinding mechanism 6 includes a motor 601. An inverted L-shaped fixing bracket 602 is fixedly installed on the opposite sides of the two sets of rectangular frames 506. A rotating shaft 603 is fixedly installed at the output end of the motor 601. A grinding head 604 is fixedly installed at one end of the rotating shaft 603 through the inverted L-shaped fixing bracket 602. A sensor 7 is fixedly installed at the top of the spring support frame 2. A controller 13 is fixedly installed on one side of the bracket 1, and the controller 13 is signal-connected to the sensor 7. The controller 13 is electrically connected to the control end of the dual-head motor 501. A guide rod 8 is fixedly installed at the bottom of the bracket 1 directly below the screw 502. Two sets of guide blocks 9 are slidably connected to the outer surface of the guide rod 8. A connecting block 10 is fixedly connected between the two sets of guide blocks 9 and the two sets of moving blocks 504 respectively.

[0031] By placing the spring body 3 to be ground on top of the spring support 2, the dual-head motor 501 drives the two sets of screws 502 to rotate and the two sets of moving blocks 504 to move closer together until the two sets of grinding heads 604 respectively abut against the two end faces of the spring body 3. Then, the two sets of motors 601 are turned on to drive the two sets of rotating shafts 603 to rotate. The rotating shafts 603, in conjunction with the grinding heads 604, grind both ends of the spring body 3. At the same time, the sensor 7 detects the position and size of the spring body 3 and transmits the signal to the controller 13. When the sensor 7 detects that the spring body 3 and the grinding head 604 are in contact, the controller will take action. When there is no contact, the dual-head motor 501 is restarted by the controller 13 until the sensor 7 detects that the spring body 3 is in contact with the grinding head 604. The controller 13 then controls the dual-head motor 501 to stop running, thus ensuring both the grinding effect on the end face of the spring body 3 and improving the grinding efficiency. When the two sets of moving blocks 504 move, they drive the two sets of connecting blocks 10 and guide blocks 9 to move. The two sets of guide blocks 9 slide along the surface of the connecting blocks 10, which guides the moving blocks 504 and improves the stability of the moving blocks 504 during movement.

[0032] Reference Figure 1-3Limit blocks 18 are fixedly installed at one end of each of the two sets of screws 502 near the dual-head motor 501; clamping mechanisms 11 are provided on both sides of the top of the bracket 1 located on the spring body 3. The clamping mechanism 11 includes two sets of fixing frames 1101. The two sets of fixing frames 1101 are fixedly installed on the side wall of the bracket 1. An electric push rod 1102 is fixedly installed on the top of the fixing frame 1101. A clamping block 1103 is fixedly installed on the telescopic end of the electric push rod 1102.

[0033] The position of the moving block 504 is restricted by the limiting block 18 to prevent the moving block 504 from falling off the surface of the screw 502, thus improving its practicality during use. The two sets of electric push rods 1102 extend and retract to drive the two sets of clamping blocks 1103 to move, thereby clamping the spring body 3, improving the stability of the spring body 3 during the processing, and helping to improve the processing accuracy of the spring body 3.

[0034] Reference Figure 2-4 Both sets of clamping blocks 1103 have anti-slip pads 12 fixedly installed on their tops; the threads of the two sets of screws 502 are opposite in direction; the anti-slip pads 12 increase the friction between the clamping blocks 1103 and the spring body 3, preventing the spring body 3 from sliding during processing and improving the stability of the spring body 3 during processing; the opposite thread directions of the two sets of screws make it easier for the two sets of rotating seats 503 to move closer or further apart synchronously when the double-headed motor 501 drives the two sets of screws 502 to rotate in the forward or reverse direction.

[0035] Reference Figure 1-3 An isolation cover 14 is fixedly installed on the top of the bracket 1 around the outer periphery of the two grinding mechanisms 6. Two sets of cover doors 15 are slidably connected to the side wall of the isolation cover 14. The interior of each set of cover doors 15 is provided with a groove 16 that matches the clamping mechanism 11. An observation window 17 is fixedly installed on the front surface of each set of cover doors 15. The cover doors 15 block the dust generated during the grinding process of the grinding head 604 and the spring body 3, which helps to prevent a large amount of dust from entering the working environment and helps to maintain the cleanliness of the working environment. The observation window 17 allows the staff to observe the processing of the spring body 3, which improves the practicality of use.

[0036] Working principle: The spring body 3 to be ground is placed on top of the spring support 2. The dual-head motor 501 drives two sets of screws 502 to rotate, bringing the two sets of moving blocks 504 closer together until the two grinding heads 604 contact the two end faces of the spring body 3. Then, the two sets of motors 601 are turned on to drive the two sets of rotating shafts 603 to rotate. The rotating shafts 603, in conjunction with the grinding heads 604, grind both ends of the spring body 3. At the same time, the sensor 7 detects the position and size of the spring body 3 and transmits the signal to the controller 13. When the sensor 7 detects... When it is detected that the spring body 3 is not in contact with the grinding head 604, the controller 13 controls the dual-head motor 501 to start again until the sensor 7 detects that the spring body 3 is in contact with the grinding head 604. Then the controller 13 controls the dual-head motor 501 to stop running, thus ensuring the grinding effect on the end face of the spring body 3 and improving the grinding efficiency. The position of the moving block 504 is restricted by the limit block 18 to prevent the moving block 504 from falling off the surface of the screw 502, thus improving the practicality during use.

[0037] Among them, the two sets of moving blocks 504 drive the two sets of connecting blocks 10 and guide blocks 9 to move when they move. The two sets of guide blocks 9 slide along the surface of the connecting blocks 10, which guides the moving blocks 504 and improves the stability of the moving blocks 504 when they move. The two sets of electric push rods 1102 extend and retract to drive the two sets of clamping blocks 1103 to move, thereby clamping the spring body 3 and improving the stability of the spring body 3 during the processing, which is conducive to improving the processing accuracy of the spring body 3.

[0038] Meanwhile, the anti-slip pad 12 increases the friction between the clamping block 1103 and the spring body 3, preventing the spring body 3 from sliding during processing and improving the stability of the spring body 3 during processing; the cover 15 blocks the dust from the grinding head 604 during the grinding process of the spring body 3, which helps to prevent a large amount of dust from entering the working environment and helps to maintain the cleanliness of the working environment.

[0039] In addition, by having the two sets of threads in opposite directions, when the dual-head motor 501 drives the two sets of screws 502 to rotate in the forward or reverse direction, it is beneficial for the two sets of rotating seats 503 to move closer or further apart synchronously; the observation window 17 makes it easy for staff to observe the processing of the spring body 3, thus improving its practicality during use.

[0040] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
