[0004] The aforementioned bushing processing device results in a high surface temperature on the bushing after processing. Workers need to cool the bushing before proceeding with subsequent processing. The natural cooling of the bushing takes a long time, which wastes a lot of time and affects production efficiency. Summary of the Invention

[0005] In order to reduce the cooling time required for bushings and improve production efficiency, this application provides a bushing processing device with a cooling function.

[0006] This application provides a bushing machining device with a cooling function, which adopts the following technical solution: A bushing machining device with cooling function includes a chuck and a cutting element located on a frame. The chuck is vertically arranged and connected to the frame, contacting the bushing and used for clamping and limiting the bushing. The cutting element contacts the bushing and is used for machining the bushing. It also includes a rotating component, a cooling plate, a cooling box, and a drive mechanism located on the frame. The rotating component is located on one side of the clamping component, connected to the clamping component, and used to drive the clamping component to rotate. The rotating component includes a drive motor, a driving wheel, and a driven wheel. The drive motor is located on the frame and connected to the frame, and the output shaft of the drive motor is coaxially connected to the driving wheel. The driving wheel is located on one side of the bushing and connected to the frame. The driven wheel is located on one side of the driving wheel and connected to the frame. The driven wheel is coaxially connected to the chuck and meshes with the driving wheel. The cooling plate is vertically arranged and located at the bottom of the bushing. The cooling plate is connected to the frame. The top of the cooling plate contacts the outer wall of the bushing. The bottom of the cooling plate extends into the cooling box and contacts the cooling water inside the cooling box. The cooling box has an opening and is connected to the frame. The drive mechanism is located on the cooling box and is connected to the cooling plate and is used to drive the cooling plate to move along the length of the cooling box.

[0007] By adopting the above technical solution, after the bushing is processed, the operator starts the drive motor. The output shaft of the drive motor rotates, which drives the drive wheel to rotate synchronously, thereby driving the chuck and bushing to rotate synchronously. The outer peripheral wall of the bushing contacts the top of the cooling plate, thereby transferring the heat on the bushing to the cooling plate and finally to the cooling water in the cooling tank, thus accelerating the dissipation of heat from the bushing and accelerating the cooling speed of the bushing. At the same time, the operator adjusts the drive mechanism, thereby driving the cooling plate to move synchronously, thereby increasing the contact area between the cooling plate and the bushing, thereby further improving the cooling effect.

[0008] Preferably, the cooling box is provided with a rotating motor, a rotating shaft and a blade. The rotating motor is located on the cooling box and connected to the cooling box. The output shaft of the rotating motor rotates through the side wall of the cooling box and is coaxially connected to the rotating shaft. The rotating shaft is horizontally arranged. The end of the rotating shaft away from the rotating motor passes through the cooling plate and contacts the cooling plate. The blade is sleeved on the rotating shaft and coaxially connected to the rotating shaft.

[0009] By adopting the above technical solution, the staff starts the rotating motor, and the output shaft of the rotating motor rotates synchronously, thereby driving the blades to rotate synchronously, thereby improving the flow of cooling water in the cooling tank, thereby improving the cooling effect of the cooling water, and thus improving the cooling effect on the cooling plate, and thus accelerating the cooling effect of the bushing.

[0010] Preferably, the driving mechanism includes a cylinder, a driving rod, and a clamping block. The cylinder is located on the side of the cooling box away from the rotating motor. The cylinder body is connected to the side wall of the cooling box. The axial direction of the piston rod of the cylinder is consistent with the length direction of the cooling box. After passing through the cooling box, the piston rod of the cylinder is connected to the end of the driving rod. The driving rod is coaxially arranged with the rotating shaft. The side of the driving rod away from the cylinder is connected to the clamping block. A driving groove is coaxially formed on the driving rod. The side wall of the driving groove contacts the side wall of the rotating shaft. The clamping block is vertically arranged. The clamping block is sleeved on the rotating shaft and contacts the side wall of the rotating shaft. A clamping groove is formed on the clamping block. The clamping groove is vertically arranged. The side wall of the clamping groove contacts the two side walls of the cooling plate.

[0011] By adopting the above technical solution, the clamping block supports and clamps the cooling plate. When the operator starts the cylinder, the piston rod of the cylinder extends and retracts, causing the drive rod to move synchronously with the clamping block. Through the clamping groove on the clamping block, the cooling plate moves synchronously with the clamping block, thereby increasing the contact area between the cooling plate and the bushing, thus improving the cooling speed of the cooling plate on the bushing, reducing the time required for the bushing to cool, and accelerating the production and processing efficiency.

[0012] Preferably, there are multiple cooling plates, drive rods, clamping blocks, and blades, and the multiple cooling plates, drive rods, clamping blocks, and blades are evenly spaced along the axial direction of the rotating shaft. Each cooling plate, drive rod, clamping block, and blade corresponds to one another. A connecting rod is provided on each cooling plate, and the axial direction of the connecting rod is consistent with the axial direction of the bushing. The connecting rod is connected to the multiple cooling plates.

[0013] By adopting the above technical solution, multiple cooling plates increase the contact area between the cooling plates and the outer wall of the bushing. At the same time, multiple blades further improve the flow of cooling water within the cooling curve, thereby further improving the cooling effect of the cooling water on the cooling plates and bushing. In addition, through the connecting rod, multiple cooling plates move synchronously with multiple drive rods, thereby further improving the flow of cooling water and thus increasing the cooling speed.

[0014] Preferably, a support plate, a lifting block, a blower pipe, and a vacuum pump are provided on the side of the cooling box near the rotating motor. The support plate is vertically arranged and located on the support plate. The bottom of the support plate is connected to the cooling box. A vertical groove is formed on the support plate. The vertical groove is vertically arranged. The lifting block is vertically arranged and located in the vertical groove. The side wall of the lifting block is in contact with the side wall of the vertical groove. One end of the blower pipe is connected to the lifting block and the pipe opening faces the cooling plate. The other end of the blower pipe is connected to the vacuum pump. The vacuum pump is located on one side of the cooling box and connected to the frame.

[0015] By adopting the above technical solution, the support plate supports the lifting block and the air blowing pipe. When the operator starts the vacuum pump, the air blown out by the vacuum pump comes into contact with the cooling plate after passing through the air blowing pipe, thereby cooling the cooling plate and accelerating the heat transfer between the bushing and the cooling plate, thus accelerating the cooling speed of the bushing.

[0016] Preferably, a limiting groove is formed on the side wall of the vertical groove, the limiting groove is vertically arranged, and a lifting component is provided on the lifting block to drive the lifting block to move up and down. The lifting component includes a lifting motor, a screw, and a limiting block. The lifting motor is located at the top of the support plate and is connected to the support plate. The output shaft of the lifting motor passes through the support plate and extends into the vertical groove and is coaxially connected to the screw. The screw is vertically arranged and located in the vertical groove. One end of the screw is threaded through the lifting block and connected to the bottom of the vertical groove. The limiting block is vertically arranged, located on the side wall of the lifting block and connected to the lifting block. One side of the limiting block extends into the limiting groove and contacts the side wall of the limiting groove.

[0017] By adopting the above technical solution, the staff starts the lifting motor. The output shaft of the lifting motor rotates, which drives the screw to rotate synchronously. Through the limit block and the limit groove, the lifting block moves up and down along the length of the limit groove, thereby driving the nozzle of the blower pipe to move up and down synchronously. This increases the contact area between the air blown out of the nozzle of the blower pipe and the cooling plate, accelerates the cooling speed of the cooling plate, and thus accelerates the cooling speed of the bushing.

[0018] Preferably, the clamping groove is provided with a spring and an abutment plate. The spring is horizontally arranged and located in the clamping groove. One end of the spring is connected to the side wall of the clamping groove, and the other end of the spring is connected to the abutment plate. The abutment plate is vertically arranged and located on one side of the cooling plate. The side wall of the abutment plate abuts against the cooling plate.

[0019] By adopting the above technical solution, when the cooling plate moves along the axial direction of the bushing, the elastic potential energy of the spring causes the abutment plate to abut and limit the cooling plate, thereby improving the stability of the cooling plate and making it less likely for the cooling plate to move arbitrarily and cause the cooling plate to detach from the bushing. At the same time, through the contact between the abutment plate and the cooling plate, heat is transferred to the cooling plate, so that part of the heat on the cooling plate is transferred to the abutment plate, thereby accelerating the cooling speed of the cooling plate.

[0020] Preferably, a plurality of balls are provided on the side wall of the rotating shaft, the plurality of balls are evenly distributed along the circumference of the rotating shaft, one side of each ball is connected to the side wall of the rotating shaft, and the other side of each ball is in contact with the inner side wall of the drive rod.

[0021] By adopting the above technical solution, the ball bearings convert the sliding friction between the drive groove of the drive rod and the side wall of the shaft into rolling friction, thereby reducing the friction between the drive rod and the shaft, reducing the wear of the drive rod and the shaft, and extending the service life of the drive rod.

[0022] In summary, this application includes at least one of the following beneficial technical effects: 1. After the workers process the bushing, the top of the cooling plate contacts the outer peripheral wall of the bushing, thereby transferring the heat from the bushing to the cooling plate and finally to the cooling water in the cooling tank, thus accelerating the cooling speed of the bushing. The workers start the rotating parts, which drives the chuck and bushing to rotate synchronously, thereby increasing the contact area between the bushing and the cooling plate, so that the bushing can be cooled evenly. This makes the bushing less likely to be damaged due to uneven cooling speed, improving the cooling quality of the bushing, and thus improving the processing quality of the bushing. 2. When the operator starts the cylinder, the piston rod of the cylinder extends and retracts, which drives the drive rod to move synchronously. Through the spring on the clamping block and the abutment plate, the cooling plate moves synchronously, further increasing the contact area between the cooling plate and the bushing, thereby improving the cooling effect of the cooling plate. 3. One side of the ball contacts the inner wall of the drive groove, and the other side of the ball contacts the side wall of the shaft, thereby reducing wear between the drive groove and the shaft and extending the service life of the drive rod. At the same time, the ball transfers the heat from the drive rod to the clamping block to the shaft, further cooling the cooling plate and improving the cooling effect of the cooling plate on the bushing.

[0029] The present application will be further described in detail below with reference to all the accompanying drawings.

[0030] This application discloses a bushing processing device with a cooling function.

[0031] Reference Figure 1 and Figure 2 A bushing 12 machining device with a cooling device includes a frame 1. A chuck 11, a cutting element 13, and a rotating element 2 are mounted on the frame 1. The vertically arranged chuck 11 is rotatably connected to the frame 1 and contacts the bushing 12, serving to clamp and limit its movement. The cutting element 13 is located on one side of the chuck 11, contacts the bushing 12, and is used for machining the bushing 12. The rotating element 2 includes a drive motor 21, a driving wheel 22, and a driven wheel 23. The drive motor 21 is located on the frame 1 and fixedly connected to it. The output shaft of the drive motor 21 is coaxially fixedly connected to the driving wheel 22. The driving wheel 22 is located on one side of the bushing 12 and rotatably connected to the frame 1. The driven wheel 23 is located on one side of the driving wheel 22 and rotatably connected to the frame 1. The driven wheel 23 is coaxially fixedly connected to the chuck 11 and meshes with the driving wheel 22.

[0032] The operator transfers the machined bushing 12 to the chuck 11, and then starts the drive motor 21. The output shaft of the drive motor 21 rotates, causing the drive wheel 22 to rotate synchronously. The driven wheel 23 meshes with the drive wheel 22, so that the driven wheel 23 rotates with the drive wheel 22, thereby driving the chuck 11 to rotate synchronously, which in turn causes the bushing 12 to rotate synchronously. This allows the bushing 12 to cool down quickly, reducing the cooling time required and improving processing efficiency.

[0033] Reference Figure 2 and Figure 3The bottom of the bushing 12 is equipped with a cooling box 14, a rotating motor 31, a rotating shaft 32, a cooling plate 15, a connecting rod 33, and a blade 34. The cooling box 14, which has an opening, is located at the bottom of the bushing 12, and the bottom of the cooling box 14 is fixedly connected to the frame 1. Cooling water is placed inside the cooling box 14. The rotating motor 31 is located on the side of the cooling box 14 away from the drive motor 21. The rotating motor 31 is fixedly connected to the side wall of the cooling box 14. The output shaft of the rotating motor 31 rotates through the side wall of the cooling box 14 and is coaxially fixedly connected to the rotating shaft 32. The axial direction of the horizontally arranged rotating shaft 32 is consistent with the axial direction of the bushing 12. The end of the rotating shaft 32 away from the rotating motor 31 passes through the cooling plate 15 and is rotatably connected to the inner side wall of the cooling box 14. Multiple sets of balls 35 are installed on the rotating shaft 32. Specifically, there are three sets of balls 35, and the three sets of balls 35 are evenly distributed along the axial direction of the rotating shaft 32. Specifically, each set of balls 35 includes six balls 35, which are evenly distributed along the circumference of the rotating shaft 32. One side of each ball 35 is rotatably connected to the side wall of the rotating shaft 32.

[0034] There are multiple vertically arranged cooling plates 15, specifically three, which are evenly distributed along the axial direction of the rotating shaft 32. Each cooling plate 15 is fitted onto and in contact with the rotating shaft 32. The top of each cooling plate 15 contacts the outer wall of the bushing 12, and the bottom of each cooling plate 15 extends into the cooling tank 14 and contacts the cooling water. A horizontally arranged connecting rod 33 is located at the bottom of the cooling plate 15, and the axial direction of the connecting rod 33 is consistent with the axial direction of the bushing 12. The connecting rod 33 is fixedly connected to the three cooling plates 15. There are three vertically arranged blades 34, each corresponding to one of the three cooling plates 15. Each blade 34 is fitted onto the rotating shaft 32 and is coaxially fixedly connected to the rotating shaft 32.

[0035] After the bushing 12 is machined, the heat on the bushing 12 is transferred to the cooling water in the cooling tank 14 after passing through the cooling plate 15. This conducts heat to the cooling plate 15, thereby cooling the bushing 12 and accelerating its cooling speed. This reduces the cooling time required for the bushing 12 and improves production efficiency. Simultaneously, the operator starts the rotating motor 31. The output shaft of the rotating motor 31 rotates, causing the rotating shaft 32 to rotate synchronously. This causes the impeller 34 to rotate synchronously, increasing the flow of cooling water in the cooling tank 14. This makes it easier for heat from the cooling plate 15 to be transferred to the cooling water, further accelerating the cooling process.

[0036] Reference Figure 1 , Figure 2 and Figure 3A drive mechanism 4 for moving the cooling plates 15 is installed on the cooling box 14. The drive mechanism 4 includes a cylinder 41, a drive rod 42, and a clamping block 43. The cylinder 41 is located on the side of the cooling box 14 away from the rotating motor 31. The cylinder body of the cylinder 41 is fixedly connected to the side wall of the cooling box 14. The axial direction of the piston rod of the cylinder 41 is consistent with the axial direction of the bushing 12. After passing through the cooling box 14, the piston rod of the cylinder 41 is fixedly connected to the end of the drive rod 42, and the rotation axis of the piston rod of the cylinder 41 is parallel to the rotation axis of the drive rod 42. There are multiple horizontally arranged drive rods 42. Specifically, there are three drive rods 42, and the three drive rods 42 are evenly distributed along the axial direction of the rotating shaft 32. Each drive rod 42 corresponds to each cooling plate 15. Each drive rod 42 is coaxial with the rotating shaft 32, and one end of the drive rod 42 is fixedly connected to the piston rod of the cylinder 41, and the other end of the drive rod 42 is fixedly connected to the clamping block 43. Each drive rod 42 has a coaxial drive groove 51 that extends horizontally through the drive rod 42. The sidewall of the drive groove 51 contacts the sidewall of the multiple balls 35. There are three vertically arranged clamping blocks 43, each corresponding to one of the three cooling plates 15. Each clamping block 43 is located between an adjacent drive rod 42 and a blade 34. Each clamping block 43 is sleeved on the rotating shaft 32 and contacts the side wall of the rotating shaft 32. Each clamping block 43 has a clamping groove 52 that extends vertically through the clamping block 43. The side wall of the clamping groove 52 contacts the two side walls of the cooling plate 15. A spring 61 and an abutment plate 62 are installed in each clamping groove 52. The horizontally arranged spring 61 is located in the clamping groove 52, with one end of the spring 61 fixedly connected to the side wall of the clamping groove 52 and the other end of the spring 61 fixedly connected to the abutment plate 62. The vertically arranged abutment plate 62 is located on one side of the cooling plate 15, and the side wall of the abutment plate 62 abuts against the cooling plate 15.

[0037] Multiple baffles 53 are installed on the rotating shaft 32. Specifically, there are three baffles 53, and each of the three baffles 53 corresponds to one of the three cooling plates 15. Each vertically arranged baffle 53 is located between the clamping block 43 and the blade 34. Each baffle 53 is sleeved on the rotating shaft 32 and fixedly connected to the side wall of the rotating shaft 32. This makes it less likely for the drive rod 42, the clamping block 43 and the cooling plate 15 to move excessively and cause the clamping block 43 to collide with the blade 34, thereby improving production safety.

[0038] Spring 61 and abutment plate 62 abut and limit the cooling plate 15, thereby keeping the relative position of the cooling plate 15 and clamping block 43 unchanged and improving the stability of the cooling plate 15. When the operator starts cylinder 41, the piston rod of cylinder 41 extends and retracts, driving drive rod 42 to move synchronously, thereby driving clamping block 43 to move axially along rotating shaft 32. Through spring 61 and abutment plate 62, the cooling plate 15 on the side near cylinder 41 moves synchronously. Through connecting rod 33, multiple cooling plates 15 move synchronously, thereby increasing the contact area between cooling plate 15 and bushing 12, making bushing 12 cool evenly, thereby improving the cooling effect of bushing 12 and thus improving the machining quality of bushing 12.

[0039] Reference Figure 4 and Figure 5 The cooling box 14 is equipped with a support plate 7, a lifting block 81, an air blowing pipe 82, and a vacuum pump 83. The vertically arranged support plate 7 is located on the side of the support plate 7 closest to the rotating motor 31. The bottom of the support plate 7 is fixedly connected to the top of the cooling box 14. A vertical groove 71 is formed on the support plate 7. The vertical groove 71 is vertically arranged. Two limiting grooves 72 are formed on the side wall of the vertical groove 71. The two vertically arranged limiting grooves 72 are located on both sides of the vertical groove 71, and each limiting groove 72 is connected to the vertical groove 71. A horizontal plate 73 is installed on the top of the support plate 7. The bottom of the horizontal plate 73 is fixedly connected to the top of the support plate 7.

[0040] A vertically positioned lifting block 81 is located within a vertical groove 71, with its sidewall in contact with the sidewall of the groove 71. A lifting component 9 is mounted on the lifting block 81, comprising a lifting motor 91, a screw 92, and a limiting block 93. The lifting motor 91 is located at the top of a horizontal plate 73 and is fixedly connected to it. The output shaft of the lifting motor 91 passes through the horizontal plate 73 and extends into the vertical groove 71. The vertically positioned screw 92 is located within the vertical groove 71, with one end coaxially fixedly connected to the output shaft of the lifting motor 91, and the other threaded end threaded through the lifting block 81 and rotatably connected to the bottom of the vertical groove 71. Two vertically positioned limiting blocks 93 are located on either side of the lifting block 81. One side of each limiting block 93 is fixedly connected to the sidewall of the lifting block 81, and the other side of each limiting block 93 extends into the limiting groove 72 and contacts the sidewall of the limiting groove 72. The air blowing pipe 82 is made of a stretchable flexible material. One end of the air blowing pipe 82 is fixedly connected to the lifting block 81, and the opening of the air blowing pipe 82 faces the cooling plate 15. The other end of the air blowing pipe 82 is connected to the vacuum pump 83, which is located on one side of the cooling box 14 and fixedly connected to the frame 1.

[0041] The operator starts the vacuum pump 83. The cold air blown out by the vacuum pump 83 is transferred to the cooling plate 15 after passing through the air blower 82, thereby cooling the cooling plate 15 and increasing the temperature difference between the cooling plate 15 and the bushing 12. This further accelerates the heat transfer between the bushing 12 and the cooling plate 15, thus speeding up the cooling rate of the bushing 12 and reducing the cooling time required, thereby improving production efficiency. At the same time, the operator starts the lifting motor 91. The output shaft of the lifting motor 91 rotates, driving the screw 92 to rotate synchronously. Through the limit block 93 and the limit groove 72, the lifting block 81 moves up and down vertically in the vertical groove 71, thereby driving the air blower 82 to move up and down synchronously. This increases the contact area between the air blown out by the air blower 82 and the cooling plate 15, thereby increasing the cooling speed.

[0042] The implementation principle of the bushing 12 processing device with cooling device in this application embodiment is as follows: After the operator processes the bushing 12 with the cutting part 13, the operator starts the drive motor 21. The output shaft of the drive motor 21 rotates, driving the drive wheel 22 to rotate. Through the driven wheel 23, the chuck 11 rotates synchronously, thereby driving the bushing 12 to rotate. Through the cooling plate 15, the heat on the bushing 12 is transferred to the cooling box 14.

[0043] The operator then activates cylinder 41. The piston rod of cylinder 41 extends and retracts, causing drive rod 42 to move synchronously. Through spring 61 in clamping groove 52 and abutment plate 62, cooling plate 15 moves synchronously along the axial direction of bushing 12. Through connecting rod 33, the three cooling plates 15 move synchronously, increasing the contact area between cooling plate 15 and bushing 12. This makes it easier for heat on bushing 12 to be transferred to cooling plate 15, facilitating rapid cooling of bushing 12 and reducing the time required for the operator to wait for bushing 12 to cool down. Simultaneously, the operator activates rotating motor 31. The output shaft of rotating motor 31 rotates, causing rotating shaft 32 to rotate synchronously, which in turn drives blade 34 to rotate synchronously. Blade 34 increases the flow of cooling water in cooling tank 14, allowing the cooling water to quickly cool cooling plate 15, thereby improving the cooling effect.

[0044] The staff then restarts the lifting motor 91. The output shaft of the lifting motor 91 rotates, causing the screw 92 to rotate synchronously. Through the limit block 93 and the limit groove 72, the lifting block 81 rises and falls vertically, thereby causing the air blower 82 to rise and fall synchronously. This increases the contact area between the air blown out by the air blower 82 and the cooling plate 15, thereby causing the cooling plate 15 to cool down quickly, which in turn causes the bushing 12 to cool down quickly, thus reducing the cooling time required for the bushing 12 and improving production efficiency.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
