[0002] Ball screws are important transmission components in mechanical systems and are widely used in fields such as machine tools, automation equipment, communication equipment, robots, electronic equipment, and precision machinery. They have the characteristics of high precision, high speed, and high rigidity, and can meet the high requirements of automation equipment for transmission components.

[0003] During the production process of ball screws, uneven burrs or depressions on their surfaces will affect the transmission efficiency and service life of the equipment. Therefore, polishing treatment is an essential process. However, the existing polishing equipment on the market has certain limitations. Especially when processing ball screws with different radii, it is necessary to manually adjust the rotation speed and pressure of the polishing machine in multiple directions, which reduces the production efficiency.

[0004] In view of this, this application is specifically proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an automatic polishing machine for ball screws to solve the problems raised in the above background art.

[0006] To solve the above technical problems, an automatic polishing machine for ball screws provided by the utility model includes a base. A grinding box is fixedly installed on the top of the base. A fixed rod is fixedly installed at the bottom end of the inner wall of the grinding box. A plurality of telescopic polishing mechanisms are fixedly installed at the bottom of the fixed rod.

[0007] The telescopic polishing mechanism includes a hollow rod fixedly installed at the bottom of the fixed rod. A spring is fixedly connected to the top end inside the hollow rod. One end of the spring away from the hollow rod is fixedly connected to a support rod. The support rod is sleeved inside the hollow rod. A protection rod is fixedly installed at the bottom of the support rod. A fixed column is sleeved inside the protection rod and the support rod. A motor is rotatably installed at the top of the fixed column. A second telescopic column is fixedly connected to the top of the motor. A second wire is fixedly connected to the center of the top of the motor. A grinding head is fixedly installed at one end of the fixed column away from the motor.

[0008] Furthermore, a support plate is fixedly installed on one side of the top of the base away from the grinding box. A first rotating shaft is rotatably installed on the side wall of the support plate. A conveyor belt is connected to the outer wall of the first rotating shaft. A fixing plate is connected to the side wall of the conveyor belt. A baffle is fixedly installed on the side wall of the top of the fixing plate.

[0009] Further, a support column is fixedly installed at the top inside the grinding box on the base. A sliding block is fixedly installed on the surface of the support column. The sliding block is connected to a second rotating shaft. A sliding groove is formed on one side of the second rotating shaft close to the support column. The sliding block is connected to the inner wall of the sliding groove. A first telescopic column is fixedly installed on the side wall of the sliding block. The side of the first telescopic column away from the sliding block is fixedly installed on the inner wall of the sliding groove. A roller is rotatably installed on the outer wall of the second rotating shaft.

[0010] Further, a control cabinet is fixedly installed on the outer wall of the grinding box. A window is opened on the top of the control cabinet. A keyboard laminar board is opened on one side of the control cabinet away from the grinding box. A blower cabinet is fixedly installed at the bottom of the control cabinet. A blower is installed inside the blower cabinet. A cabinet door is opened on the outer wall of the blower cabinet. A first handle is fixedly installed on the surface of the cabinet door. A power distribution block is fixedly installed at the bottom end of the side wall of the blower cabinet away from the grinding box. One side of the power distribution block away from the blower cabinet is fixedly connected to a first electric wire.

[0011] Further, air holes are formed on the top surface of the base. An air suction pipe is connected to the outer wall of the base close to the blower cabinet.

[0012] Further, a dust collection drawer is opened at the bottom of one side of the base away from the support plate. A second handle is fixedly installed on the surface of the dust collection drawer.

[0013] Further, an observation window is opened on one side of the grinding box close to the control cabinet. The material of the observation window is acrylic.

[0014] Further, the material of the outer wall of the roller is rubber. Anti-slip patterns are integrally formed on both the roller and the conveyor belt surface.

[0015] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the lead screw enters the surface of the roller through the conveyor belt, the bottom of the protection rod contacts the lead screw and is squeezed, causing the support rod to retract upward, triggering elastic deformation of the spring. At this time, the grinding head in the support rod extends out, avoiding damage to the cutter head caused by the surface of the lead screw squeezing the cutter head when lead screws with different radii are fed. When the grinding head contacts the surface of the lead screw, the motor starts to grind it. When the lead screw rotates forward, the second telescopic column at the top of the motor undergoes elastic deformation, causing the grinding head to fit onto the surface of the lead screw for grinding. The entire telescopic grinding mechanism only needs to adjust the length of the cutter head extending out before grinding, and can grind lead screws with different radii, avoiding multi-directional adjustment of the polishing machine by manual labor and improving production efficiency.

Specific implementation manners

[0022] 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. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: an automatic ball screw polishing machine, including a base 1, a grinding box 6 is fixedly installed on the top of the base 1, a fixed rod 16 is fixedly installed at the bottom end of the inner wall of the grinding box 6, and a plurality of telescopic polishing mechanisms are fixedly installed at the bottom of the fixed rod 16;

[0024] The telescopic polishing mechanism includes a hollow rod 17 fixedly installed at the bottom of the fixed rod 16. At the top end inside the hollow rod 17, a spring 30 is fixedly connected. One end of the spring 30 away from the hollow rod 17 is fixedly connected to a support rod 18. The support rod 18 is sleeved inside the hollow rod 17. At the bottom of the support rod 18, a protection rod 19 is fixedly installed. A fixing column 34 is sleeved inside the protection rod 19 and the support rod 18. At the top of the fixing column 34, a motor 32 is rotatably installed. At the top of the motor 32, a second telescopic column 31 is fixedly connected. At the center of the top of the motor 32, a second wire 33 is fixedly connected. At one end of the fixing column 34 away from the motor 32, a grinding head 29 is fixedly installed.

[0025] It should be noted that when the ball screw enters the grinding mechanism, only the set screw thread depth needs to be input. When the protection rod 19 touches the outer wall of the screw, as the protection rod 19 is squeezed, the support rod 18 will retract upward into the hollow rod 17. At this time, the second telescopic column 31 will extend to the preset length, and the motor 32 fixed to the top of the fixing column 34 and the connected grinding head 29 will correspondingly extend until the grinding head 29 touches the surface of the screw, and then start the grinding operation on the screw. This avoids damage to the grinding head 29 caused by the surface of the screw squeezing the grinding head 29 when screws of different radii are fed.

[0026] Refer to Figure 1 As shown in the figure, for an automatic ball screw polishing machine, on one side of the top of the base 1 away from the grinding box 6, a support plate 2 is fixedly installed. On the side wall of the support plate 2, a first rotating shaft 3 is rotatably installed. On the outer wall of the first rotating shaft 3, a conveyor belt 4 is connected. On the side wall of the conveyor belt 4, a fixing plate 35 is connected. On the top side wall of the fixing plate 35, a baffle 5 is fixedly installed.

[0027] It should be noted that the baffle 5 is usually located on the side wall at the end of the conveyor belt 4. When the screw advances on the conveyor belt 4, the baffle 5 will act as a physical obstacle to restrict the lateral movement of the screw and force it to vertically enter the grinding mechanism along a predetermined path.

[0028] Refer to Figures 1-2 As shown in the figure, for an automatic ball screw polishing machine, on the top inside the grinding box 6 of the base 1, a support column 20 is fixedly installed. On the surface of the support column 20, a sliding block 36 is fixedly installed. The sliding block 36 is connected to a second rotating shaft 21. On one side of the second rotating shaft 21 close to the support column 20, a sliding groove 22 is opened. The sliding block 36 is connected to the inner wall of the sliding groove 22. On the side wall of the sliding block 36, a first telescopic column 23 is fixedly installed. One side of the first telescopic column 23 away from the sliding block 36 is fixedly installed on the inner wall of the sliding groove 22. On the outer wall of the second rotating shaft 21, a roller 24 is rotatably installed.

[0029] It should be noted that: through the cooperation of the sliding block 36 and the sliding groove 22, and the elastic action of the first telescopic column 23, the roller 24 on the second rotating shaft 21 can be adjusted adaptively within a certain range, so that the roller 24 can better adapt to lead screws of different diameters or sizes, ensuring stable contact of the lead screw during transmission and grinding, and avoiding slipping or wear caused by size mismatch.

[0030] Refer to Figures 1-4 As shown, on the outer wall of a ball screw automatic polishing machine, a control cabinet 8 is fixedly installed on the outer wall of the grinding box 6. A window 13 is opened at the top of the control cabinet 8. A keyboard layer board 12 is opened on one side of the control cabinet 8 away from the grinding box 6. A blower cabinet 9 is fixedly installed at the bottom of the control cabinet 8. A blower is installed inside the blower cabinet 9. A cabinet door 10 is opened on the outer wall of the blower cabinet 9. A first handle 11 is fixedly installed on the surface of the cabinet door 10. A power distribution block 14 is fixedly installed at the bottom end of the side wall of the blower cabinet 9 away from the grinding box 6. A first electric wire 15 is fixedly connected to one side of the power distribution block 14 away from the blower cabinet 9.

[0031] It should be noted that: the window 13 opened at the top of the control cabinet 8 is used to display the working status, parameter settings or alarm information of the device, enabling the operator to intuitively understand the working conditions of the device. At the same time, the setting of the keyboard layer board 12 provides an input device, allowing the operator to set parameters and operate the control of the device through a keyboard or other input devices, improving the convenience of human-machine interaction.

[0032] Refer to Figure 4 As shown, on the top surface of the base 1 of a ball screw automatic polishing machine, air holes 25 are opened. An air suction pipe 28 is connected to the outer wall of the base 1 close to the blower cabinet 9.

[0033] It should be noted that: a large amount of pollutants such as dust, debris and powder will be generated during the grinding process. By sucking out the pollutants inside the grinding box 6 through the air holes 25 and the air suction pipe 28, the pollutant concentration in the working area can be effectively reduced.

[0034] Refer to Figure 4 As shown, a dust collection drawer 26 is opened at the bottom of one side of the base 1 away from the support plate 2. A second handle 27 is fixedly installed on the surface of the dust collection drawer 26.

[0035] It should be noted that: the dust collection drawer 26, as a collection container for dust and debris, can effectively collect and store the pollutants sucked in through the air holes 25. The operator can regularly take out the dust collection drawer 26 by pulling the second handle 27 to clean the dust and debris inside, avoiding the accumulation of dust and debris inside the device or in the working area.

[0036] Refer to the figure shown. An observation window 7 is opened on one side of the grinding box 6 close to the control cabinet 8. The material of the observation window 7 is acrylic.

[0037] It should be noted that the observation window 7 allows the operator to directly observe the internal working state and the grinding process without opening the grinding box 6.

[0038] Refer to Figures 4-5 As shown, the outer wall material of the roller 24 is rubber, and both the roller 24 and the conveyor belt 4 are provided with integrally formed anti-slip patterns on their surfaces.

[0039] It should be noted that the design of the anti-slip pattern further increases the roughness of the contact surface, enabling the roller 24 to drive the lead screw more stably during rotation and avoiding the occurrence of slipping.

[0040] Working principle: When the ball screw is placed on the surface of the conveyor belt 4, the conveyor belt 4 transports the ball screw forward. When the lead screw contacts the baffle 5, the baffle 5 restricts the lateral movement of the lead screw and forces it to enter the surface of the roller 24 vertically along a predetermined path. At this time, the bottom of the protection rod 19 first contacts the lead screw. Due to the different thread radii on the surface of the lead screw, the protection rod 19 will be squeezed to different degrees. As the protection rod 19 is squeezed, the support rod 18 will retract upward into the hollow rod 17, and the spring 30 will be compressed and undergo elastic deformation, allowing the telescopic polishing mechanism to automatically adjust its position according to the diameter of the lead screw without manual adjustment. As the support rod 18 retracts, the second telescopic column 31 will extend to a preset length at this time, and the motor 32 fixed on the top of the fixed column 34 and its connected grinding head 29 will extend accordingly until the grinding head 29 contacts the surface of the lead screw, and then start the grinding operation on the lead screw. In this way, it is avoided that the surface of the lead screw squeezes the grinding head 29 when lead screws with different radii are fed, resulting in damage to the grinding head 29. When the lead screw advances and rotates on the roller 24, the second telescopic column 31 at the top of the motor 32 will further play a role. Due to the possible unevenness or slight changes on the surface of the lead screw, the elastic deformation of the second telescopic column 31 can ensure that the grinding head 29 always fits on the surface of the lead screw, maintaining a stable grinding effect. The entire grinding mechanism can automatically adapt to lead screws with different radii for grinding, avoiding multi-directional adjustment of the polishing machine by manual labor and improving production efficiency.
