Detailed implementation manners

[0031] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0032] Please refer to Figures 1-9 As shown, a technical solution provided by the present invention: a ball screw type punching and polishing machine, including a fixed table 1 for providing an installation platform for the workpiece; an operator can install and fix the workpiece according to the position of the fixed table 1.

[0033] In this embodiment, please refer to Figure 6 , a processing assembly 4 for processing the workpiece; the processing assembly 4 includes a hole position processing device for processing the hole position of the workpiece; the hole position processing device includes a rotating sleeve 401, and both sides of the rotating sleeve 401 are connected with a cross plate 406 through a connecting piece 402. Please refer to Figure 7, in this embodiment, the connecting member 402 is composed of a threaded sleeve 4021 and a threaded sleeve shaft 4022 connected in combination. It is also possible to directly use a long-axis type pin to fix the rotating sleeve 401. The use of the threaded sleeve 4021 and the threaded sleeve shaft 4022 is to prevent the pin from loosening and slipping, and the insertion-type threaded connection makes the disassembly more convenient. The cross plate 406 is slidably connected to the movable seat 306 through a chute. The cross plate 406 mainly functions to limit the position of the rotating sleeve 401. When fixed on the cross plate 406, it can directly limit the rotating sleeve 401 to move unidirectionally along the chute on the movable seat 306. An adjusting screw rod 403 is arranged in the rotating sleeve 401. One end of the adjusting screw rod 403 is connected to the ball sleeve 204 through a sleeve body, and the other end of the adjusting screw rod 403 is rotatably connected to the movable seat 306. A connecting seat 404 is connected to the rotating sleeve 401. By rotating the adjusting screw rod 403 and utilizing the threaded connection relationship between the screw rod and the threaded connection, the forward and backward movement of the rotating sleeve 401 will be controlled, and the punching drill bit 409 or the polishing processing device 410 will be moved to the processing dimension position of the required workpiece, thereby realizing the adjustment function. A second gear 408 is rotatably connected to the bottom of the connecting seat 404, and a punching drill bit 409 is inserted into the bottom of the second gear 408. A second motor 405 is installed on the cross plate 406, and the output end of the second motor 405 is connected to a first gear 407. The surface of the first gear 407 meshes with the second gear 408. When the second motor 405 is started to rotate, the second motor 405 will drive the rotation of the first gear 407. After the meshing of the bevel gears, the rotation of the punching drill bit 409 will be driven, thereby realizing downward pressing and rotary punching or drilling. When the hole processing is completed, the connecting member 402 is pulled out, and then the rotation of the rotating sleeve 401 is controlled to rotate the polishing processing device 410 to the lower side. Then, the rotating sleeve 401 and the cross plate 406 are inserted and fixed by using the connecting member 402. Then, by controlling the rotation of the first motor 201 and the second motor 405, the synchronous position downward pressing of the polishing processing device 410 can be realized, and polishing processing can be realized.

[0034] Furthermore, please refer to Figure 8Polishing device 410; used for polishing the hole positions of workpieces. There are multiple connecting seats 404, and the multiple connecting seats 404 can match punching drills 409 of different sizes, or add other rotary processing tools, such as disc cutters, to achieve diversified processing. Moreover, the multiple connecting seats 404 are circularly arrayed with the center of the rotating sleeve 401 as the axis of symmetry. The polishing device 410 is arranged on one of the connecting seats 404. The polishing device 410 includes a plug rod 4101. Inside the plug rod 4101, two elastic pieces 4102 are rotatably connected, and the two elastic pieces 4102 are elastically connected by a connecting spring 4103. By using the elastic connection of the connecting spring 4103, the two elastic pieces 4102 are always in contact with the inner wall of the hole position. When the two elastic pieces 4102 enter the hole position, due to their V-shaped structure, the tip part will enter the hole position first. Then, when continuing to move downward, the two elastic pieces 4102 will contact and contract. Since the elastic pieces 4102 themselves are elastic, when moving downward and contacting the hole position, they will be squeezed. At this time, the diamond-shaped structure will be compressed, and then the upper clamping strip 4104 and the lower clamping strip 4105 will be unhooked and separated under the action of gravity and rotational force, and will fit on the inner wall of the elastic piece 4102. At this time, the two elastic pieces 4102 will be inside the hole. By using the bevel gear transmission of the second motor 405, the rotation of the plug rod 4101 is driven, and the hole position is directly polished by rotating inside. The upper clamping strip 4104 and the lower clamping strip 4105 are respectively rotatably connected inside the two elastic pieces 4102, and the upper clamping strip 4104 and the lower clamping strip 4105 are clamped with each other. A polishing wheel 4106 is connected to the elastic piece 4102, and a clamping piece 4107 is connected to the elastic piece 4102. The clamping piece 4107 is mainly provided for clamping the sandpaper used for polishing. The operator can insert the four sides of the polishing sandpaper into the gap of the clamping piece 4107, and then rotate the locking bolt 4108. By using the pressing of the clamping piece 4107, the sandpaper is clamped and fixed. One side of the clamping piece 4107 is threadedly connected with a locking bolt 4108, and the locking bolt 4108 is rotatably connected to the elastic piece 4102. Therefore, the inner wall of the hole position can be polished and ground by using the polishing wheel 4106 and the sandpaper, improving the overall grinding effect.

[0035] Furthermore, please refer to Figures 3-5, the screw assembly 2 is used to control the displacement of the processing assembly 4; the screw assembly 2 includes a fixed seat 202, a first motor 201 is installed at the bottom of the fixed seat 202, an active screw 209 is connected to the output end of the first motor 201, a ball sleeve 204 is arranged on the active screw 209, and the protection assembly 3 is arranged on the ball sleeve 204. A plurality of steel balls are arranged inside the ball sleeve 204, and the surface of the steel balls is movably connected with the surface of the active screw 209. The rotation of the first motor 201 is controlled to drive the rotation of the active screw 209, and the rotation of the active screw 209 causes the plurality of balls arranged inside the ball sleeve 204 to roll and slide in the screw thread groove, thereby driving the ball sleeve 204 to move up and down. Compared with the transmission method of the traditional threaded screw, the method using the ball is smoother and smoother, and finally the entire processing assembly 4 is moved to a suitable height to process the workpiece.

[0036] Also, see Figure 3 , the protection component 3 is used to provide displacement protection for the screw assembly; the protection component 3 includes a contact piece 301, the contact piece 301 is slidably connected to a movable seat 306, a V-shaped groove 302 is provided on the contact piece 301, a sliding pin is slidably connected to the V-shaped groove 302, a pressure plate 303 is connected to the sliding pin, a pull rod 305 is connected to one side of the pressure plate 303, a first spring 304 is sleeved on the surface of the pull rod 305, a slot 307 is provided on the surface of the ball sleeve 204, and the other side of the pressure plate 303 is inserted into the slot 307. Because the processing depth of the traditional method relies on manual calculation and manual control, which leads to inaccuracy in the processing depth, as the first motor 201 drives the active screw rod 209 to rotate, when the ball sleeve 204 moves downward, it will drive the contact piece 301 to contact the limit seat 203. After moving downward, the contact piece 301 will slide in the movable seat 306, and the V-shaped groove 302 will drive the sliding pin to slide. The sliding of the sliding pin will drive one side of the pressure plate 303 to break away from the slot 307 position on the ball sleeve 204. At this time, as the motor rotates, the entire ball sleeve 204 will not move up and down, but will rotate synchronously with the active screw rod 209 at this position. Therefore, the processing depth control can be achieved, and the ball sleeve 204 can also be provided with processing protection to prevent the position from exceeding the tolerance and causing damage to the active screw rod 209 and the ball sleeve 204.

[0037] In addition, see Figure 3, a limiting rod 205 is connected to the fixed seat 202. By setting the limiting rod 205, sliding limitation of the limiting seat 203 can be achieved, enabling it to slide only on the limiting rod 205. The movable seat 306 is slidably connected to the surface of the limiting rod 205. The limiting seat 203 is slidably connected to the surface of the limiting rod 205. A support rod 208 is connected to the bottom of the limiting seat 203, and the support rod 208 is slidably connected to the fixed seat 202. The provided support rod 208 can also provide a certain degree of up-and-down sliding limitation, making the overall sliding of the limiting seat 203 more stable and preventing tilting and jamming.

[0038] Please refer to Figure 3 , scale lines are provided on the limiting rod 205. The provided scale lines can enable the operator to calculate the machining depth, thereby providing a machining reference to ensure that the subsequent machining depth can be more accurate. The upper plane of the fixed seat 202 is horizontally aligned with the upper plane of the fixed table 1. Since the upper plane of the fixed table 1 and the upper plane of the fixed seat 202 form the same plane, that is, the reference plane, it is more convenient and accurate for the operator to perform calculations. A rotating sleeve 206 is threadedly connected to the driving lead screw 209. The bottom of the rotating sleeve 206 is rotatably connected to a connecting sleeve 207, and the connecting sleeve 207 is connected to the limiting seat 203 through a connecting rod. By setting the rotating sleeve 206, the limiting height of the operator, that is, the machining depth, can be provided. Through the rotation of the rotating sleeve 206 and using the connection between the threads, the height of the limiting seat 203 will be driven to change, and the limiting seat 203 is used to limit the depth of the downward movement of the movable seat 306, that is, the machining component 4.

[0039] It should be noted that, please refer to Figure 9 , a cavity is provided inside the connecting seat 404, and polishing liquid is provided in the cavity. Liquid outlet holes 4110 are provided on the inserting rod 4101. The liquid outlet holes 4110 are interconnected with the cavity inside the connecting seat 404 through pipelines. A liquid adding pipe 4109 is connected to the connecting seat 404. The operator can inject polishing liquid into the cavity according to the set liquid adding pipe 4109 to achieve replenishment after consumption. Liquid outlet holes 4110 are also provided on the inserting rod 4101. During rotation, the polishing liquid inside the connecting seat 404 will also flow along the pipeline to the position of the liquid outlet holes 4110 and be thrown onto the inner wall of the hole. With the rotation of the polishing wheel 4106, the inner wall is polished efficiently. Because of the polishing liquid, the polishing effect is better.

[0040] When a ball screw type punching and polishing machine of the present invention is in use, first, the rotation of the first motor 201 can be controlled to drive the rotation of the active screw 209. The rotation of the active screw 209 causes multiple balls arranged inside the ball sleeve 204 to roll and slide within the thread grooves of the screw, thereby driving the vertical movement of the ball sleeve 204. Compared with the traditional transmission method of a threaded screw, the use of balls is smoother. Finally, the entire processing component 4 is moved to an appropriate height to process the workpiece. When it reaches the appropriate height, the adjusting screw 403 is then rotated. Using the same principle, the forward and backward movement of the rotating sleeve 401 is controlled to move the punching drill bit 409 or the polishing device 410 to the processing dimension position required for the workpiece. Then, the rotation of the second motor 405 is started. The second motor 405 will drive the rotation of the first gear 407. Through the meshing of bevel gears, the rotation of the punching drill bit 409 will be driven to achieve downward rotation type punching or drilling. When the hole position processing is completed, the connecting piece 402 is pulled out, and then the rotation of the rotating sleeve 401 is controlled to rotate the polishing device 410 to the lower position. Then, the rotating sleeve 401 and the cross plate 406 are inserted and fixed using the connecting piece 402. Then, the rotation of the first motor 201 and the second motor 405 is controlled, and the synchronous position downward pressure on the polishing device 410 can be achieved to realize polishing processing. When the two elastic pieces 4102 enter the hole position, due to their V-shaped structure, the tip part will enter the hole position first. When continuing to move downward, the two elastic pieces 4102 will contact and contract. The elastic pieces 4102 themselves are elastic. When moving downward and contacting the hole position, they will be squeezed. At this time, the diamond-shaped structure will be compressed, and then the upper clamping strip 4104 and the lower clamping strip 4105 will be decoupled and separated under the action of gravity and rotational force, and will adhere to the inner wall of the elastic piece 4102. At this time, the two elastic pieces 4102 will be inside the hole. Using the bevel gear transmission of the second motor 405, the rotation of the insertion rod 4101 is driven to directly rotate and polish inside the hole position. And through the elastic connection of the connecting spring 4103, the two elastic pieces 4102 are always in contact with the inner wall of the hole position. Small polishing wheels 4106 are provided on the two rotating elastic pieces 4102. The inner wall of the hole position is polished using the rotating polishing wheels 4106. At the same time, liquid outlet holes 4110 are provided on the insertion rod 4101. During the rotation process, the polishing liquid inside the connecting seat 404 will also flow along the pipeline to the position of the liquid outlet holes 4110 and be thrown onto the inner wall of the hole position. With the rotation of the polishing wheels 4106, the inner wall is polished efficiently. Because of the polishing liquid, the polishing effect is better.Since it is considered that the processing depth in the traditional method depends on manual calculation and manual control, resulting in inaccuracy of the processing depth, this technical solution sets up another method of control and adjustment. After the workpiece is fixed on the fixed table 1, because the upper plane of the fixed table 1 and the upper plane of the fixed seat 202 form the same plane, that is, the reference plane. Then, by rotating the rotating sleeve 206, using the rotation between the lead screw and the thread, the height change of the limit seat 203 will be driven. The limit seat 203 is used to limit the depth of the downward movement of the movable seat 306, that is, the processing component 4. Based on this as the calculation basis, then the lifting adjustment is carried out according to the scale line on the limit rod 205. After completion, when the first motor 201 drives the rotation of the driving lead screw 209 and the ball sleeve 204 moves downward, it will drive the contact piece 301 to contact the limit seat 203. After moving downward, the contact piece 301 will slide within the movable seat 306. Using the V-shaped groove 302 will drive the sliding of the sliding pin. When the sliding pin slides, it will drive one side of the pressing plate 303 to disengage from the slot 307 position on the ball sleeve 204. At this time, with the rotation of the motor, the entire ball sleeve 204 will not move up and down, but will rotate synchronously with the driving lead screw 209 at this position. Therefore, in this way, the processing control of the depth can be achieved, and the processing protection can also be provided for the ball sleeve 204 to prevent damage to the driving lead screw 209 and the ball sleeve 204 caused by position over-tolerance.
