Description

Technical Field

[0001] This utility model relates to the field of ball screw processing technology, specifically a ball screw deburring device. Background Technology

[0002] A ball screw deburring device is a device used to remove burrs from the surface of ball screws. It can improve the surface quality and precision of ball screws and is widely used in the outer diameter polishing of various shaft parts, such as crankshafts and camshafts of automobile engines. These shaft parts require high-precision outer diameter surfaces to ensure engine performance and reliability, and can improve the service life and performance of ball screws.

[0003] However, existing technologies still have the following problems:

[0004] Firstly, when deburring and polishing ball screws, manual grinding is often used. However, when polishing the outer surface of the ball screw manually, the polishing speed varies, making it impossible to polish the outer surface of the ball screw at a uniform speed, which fails to improve the quality of the ball screw.

[0005] Secondly, existing deburring devices on the market require the ball screw to be fed into the deburring device during polishing. During this process, the grinding wheel may injure the workers. The existing deburring devices are inconvenient to feed the ball screw effectively and quickly, and have low practicality.

[0006] To address the aforementioned problems, the inventors proposed a ball screw deburring device to solve them. Utility Model Content

[0007] To address the problems of inconvenience in effectively polishing burrs on the outer surface of ball screws and inconvenience in effectively and quickly feeding ball screws, the purpose of this utility model is to provide a ball screw deburring device.

[0008] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a ball screw deburring device, comprising a base plate, a pushing device fixedly connected to the top of the base plate, and a polishing device fixedly connected to both sides of the top of the base plate. The polishing device includes a motor and a bracket, the output end of the motor being rotatably connected to one end of the bracket, a guide wheel fixedly sleeved on the output end of one motor, and a grinding wheel fixedly sleeved on the output end of the other motor. A protective shell is fixedly connected to the top of the base plate, the inner wall of the protective shell being in contact with the outer surface of the grinding wheel, and the output end of one motor penetrating one end of the protective shell. A plurality of fixed rods evenly spaced are fixedly connected to the top of the base plate, and a support plate is fixedly connected to the top of the plurality of fixed rods. Baffles are fixedly connected to both sides of the top of the support plate, and the baffles can guide the ball screw to move in the correct position, ensuring good contact between the ball screw and the guide wheel and the grinding wheel.

[0009] Preferably, the pushing device includes a base, the bottom end of which is fixedly connected to one side of the top end of a base plate. A fixed box is fixedly connected to the top end of the base. A rotating shaft is movably connected through the top end of the fixed box. The bottom end of the rotating shaft is rotatably connected to the lower inner wall of the fixed box. A first bevel gear is fixedly sleeved on the outer surface of the rotating shaft. A second bevel gear is meshed with the outer surface of the first bevel gear. A motor is fixedly connected to the top end of the base. The output end of the motor passes through one end of the fixed box and is fixedly connected to one end of the second bevel gear. A rotating plate is fixedly connected to the top of the rotating shaft, and an eccentric shaft is fixedly connected to the top of the rotating plate. When the first bevel gear rotates, it drives the rotating shaft to rotate, and the rotating plate at the top of the rotating shaft rotates accordingly. Since the eccentric shaft is located at the eccentric point of the rotating plate, the eccentric shaft makes a circular motion when the rotating plate rotates. A connecting plate is rotatably connected to the top of the eccentric shaft, and a push rod is rotatably connected to one side of the bottom end of the connecting plate. A limit plate is fixedly connected to the top of the baffle. The outer surface of the push rod is in contact with the inner wall of the baffle, and the outer surface of the push rod is in contact with the inner wall of the limit plate.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0011] 1. This utility model can drive the ball screw to rotate and move forward by rotating the guide wheel, while the rotating grinding wheel grinds and removes the burrs on the surface of the ball screw, thereby achieving the purpose of effectively and evenly polishing the burrs on the outer surface of the ball screw.

[0012] 2. This utility model can achieve the purpose of conveniently and quickly pushing the ball screw into the polishing device by rotating the rotating plate, causing the eccentric shaft to make circular motion, driving the connecting plate to move, and the connecting plate to push the push rod. Under the restriction of the baffle and the limiting plate, the push rod makes linear reciprocating motion. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0019] Example: Figure 1-3 As shown, this utility model provides a ball screw deburring device, including a base plate 1. A pushing device 2 is fixedly connected to one side of the top of the base plate 1, and a polishing device 3 is fixedly connected to one side of the top of the base plate 1. The polishing device 3 includes multiple motors 31 and multiple brackets 32. The multiple motors 31 and multiple brackets 32 are all fixedly connected to the top of the base plate 1. The output end of the motor 31 is rotatably connected to one end of the bracket 32. A guide wheel 33 is fixedly sleeved on the output end of one motor 31, and a grinding wheel 34 is fixedly sleeved on the output end of another motor 31. The output end of the other motor 31 is movably connected through both ends of a protective shell 35. The protective shell 35 is fixedly connected to the top of the base plate 1. The inner wall of the protective shell 35 is in contact with the outer surface of the grinding wheel 34. Multiple fixed rods 36 are fixedly connected to the top of the base plate 1 at equal intervals. The tops of the multiple fixed rods 36 are jointly fixedly connected to a support plate 37. Baffles 38 are fixedly connected to both sides of the top of the support plate 37. The baffles 38 are "V" shaped. The baffle 38 can guide the ball screw to move in the correct position, ensuring good contact between the ball screw and the guide wheel 33 and the grinding wheel 34.

[0020] After the push rod 210 pushes the ball screw into the polishing device 3, the rotating guide wheel 33 drives the ball screw to rotate and move forward. At the same time, the rotating grinding wheel 34 grinds and removes the burrs on the surface of the ball screw, which facilitates the effective polishing of the burrs on the outer surface of the ball screw.

[0021] The pushing device 2 includes a base 201, a fixed box 202 fixedly connected to the top of the base 201, a fixed bottom of the base 201 fixedly connected to one side of the top of the base plate 1, a fixed bottom of the fixed box 202 fixedly connected to the top of the base 201, a rotating shaft 203 movably connected through the top of the fixed box 202, a rotating bottom of the rotating shaft 203 rotatably connected to the lower inner wall of the fixed box 202, a first bevel gear 204 fixedly sleeved on the outer surface of the rotating shaft 203, a second bevel gear 205 meshing with the outer surface of the first bevel gear 204, a motor 206 fixedly connected to the top of the base 201, the output end of the motor 206 passing through one end of the fixed box 202 and fixedly connected to one end of the second bevel gear 205, and the top of the rotating shaft 203... A rotating plate 207 is fixedly connected, and an eccentric shaft 208 is fixedly connected to the top of the rotating plate 207. The eccentric shaft 208 is located at the eccentric part of the rotating plate 207. When the first bevel gear 204 rotates, it drives the rotating shaft 203 to rotate. The rotating plate 207 at the top of the rotating shaft 203 rotates accordingly. Since the eccentric shaft 208 is located at the eccentric part of the rotating plate 207, the eccentric shaft 208 makes a circular motion when the rotating plate 207 rotates. A connecting plate 209 is rotatably connected to the top of the eccentric shaft 208. A push rod 210 is rotatably connected to one side of the bottom end of the connecting plate 209. A limit plate 211 is fixedly connected to the top of the baffle 38. The outer surface of the push rod 210 is in contact with the inner wall of the baffle 38, and the outer surface of the push rod 210 is in contact with the inner wall of the limit plate 211.

[0022] When the rotating plate 207 rotates, the eccentric shaft 208 makes a circular motion, which drives the connecting plate 209 to move. The connecting plate 209 then pushes the push rod 210. Under the restriction of the baffle 38 and the limiting plate 211, the push rod 210 makes a linear reciprocating motion, which facilitates the effective and rapid pushing of the ball screw into the polishing device 3.

[0023] Working principle: After the motor 206 starts, its output end drives the second bevel gear 205 to rotate. The second bevel gear 205 meshes with the first bevel gear 204, thereby causing the first bevel gear 204 to rotate, which in turn drives the rotating shaft 203 to rotate. The rotating plate 207 at the top of the rotating shaft 203 rotates accordingly. Since the eccentric shaft 208 is located at the eccentric part of the rotating plate 207, when the rotating plate 207 rotates, the eccentric shaft 208 makes a circular motion. The eccentric shaft 208 drives the connecting plate 209 to move, and the connecting plate 209 pushes the push rod 210. Under the restriction of the baffle 38 and the limiting plate 211, the push rod 210 makes a linear reciprocating motion, thereby achieving the purpose of conveniently and quickly pushing the ball screw into the polishing device 3.

[0024] Multiple motors 31 are activated. One motor 31 drives the guide wheel 33 to rotate, and another motor 31 drives the grinding wheel 34 to rotate. The output end of the motor 31 is movably connected to the protective shell 35. The protective shell 35 can protect the operator and prevent the debris generated by the grinding wheel 34 from flying when rotating at high speed. The fixing rod 36 and the support plate 37 serve to support and fix the baffle 38. The "V"-shaped baffle 38 can guide the ball screw to move in the correct position and ensure good contact between the ball screw and the guide wheel 33 and the grinding wheel 34. When the push rod 210 pushes the ball screw into the polishing device 3, the rotating guide wheel 33 drives the ball screw to rotate and move forward. At the same time, the rotating grinding wheel 34 grinds and removes the burrs on the surface of the ball screw, thereby achieving the purpose of effectively polishing the burrs on the outer surface of the ball screw.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
