[0001] This utility model relates to the field of mechanical grinding equipment, specifically a grinding device for spindle production. Background Technology

[0002] A spindle is a shaft in mechanical equipment used to support transmission components and transmit torque, bending moment, and axial force. It is typically connected to transmission elements such as bearings, gears, and pulleys to convert rotary motion into linear motion. It is widely used in machine tools, mechanical equipment, and various transmission systems. For example, in machine tools, the spindle is specifically used to clamp workpieces or cutting tools for cutting, grinding, and other machining operations; in various transmission systems, the spindle is used to transmit torque and bending moment, realizing the transmission and conversion of power.

[0003] As a core component of mechanical equipment, the performance and quality of the spindle directly affect the operating efficiency and machining accuracy of the entire equipment. Therefore, the machining accuracy requirements for spindles are extremely high, and they usually require precision grinding and polishing to ensure that their surface roughness and geometry meet design requirements. In the traditional spindle grinding process, a grinding wheel is usually used to grind the spindle. In the continuous grinding of several spindles, there are drawbacks such as grinding wheel wear, difficulty in maintaining consistent grinding accuracy, and the need for frequent grinding wheel replacement, which affects the grinding effect and efficiency of the spindle. Therefore, this application proposes a grinding device for spindle production. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a grinding device for spindle production, so as to solve the technical problems of the existing method of using grinding wheels to grind spindles, which requires frequent replacement of grinding wheels and has deviations in grinding accuracy before and after.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for spindle production, comprising a base, a clamping mechanism for clamping the spindle and driving the spindle to rotate is mounted on one side of the top of the base, a vertical arm and an adjusting base for driving the vertical arm to move laterally and longitudinally are vertically arranged on the other side of the top of the base, a winding mechanism is mounted on the top and bottom of the side of the vertical arm facing the clamping mechanism, a grinding belt for grinding is wound between the two sets of winding mechanisms, and a support member for supporting the grinding belt away from the vertical arm is arranged between the two sets of winding mechanisms.

[0006] The present invention is further configured such that the clamping mechanism includes a fixed seat vertically fixed on the base, a three-jaw chuck rotatably mounted on the top of the fixed seat facing the middle of the base, and a drive motor mounted on the fixed seat for driving the three-jaw chuck to rotate.

[0008] The present invention is further configured such that a guide groove is provided on the base, the guide groove is distributed perpendicular to the first slide block, and a slider is provided at the bottom of the first slide block to slide and engage with the guide groove.

[0009] The present invention is further configured such that a groove is formed on the upper surface of the first slide block, the second slide block is slidably fitted into the groove, and two slide rods are fixed side by side in the groove, the slide rods movably passing through the second slide block.

[0010] The present invention is further configured such that the winding mechanism includes a fixed frame fixed on the vertical arm and a winding roller rotatably mounted on the fixed frame. One end of the fixed frame is equipped with a rotating handle coaxially connected to the winding roller, and a ratchet is assembled between the rotating handle and the connecting shaft of the winding roller.

[0012] In summary, the present invention has the following main advantages:

[0013] This invention utilizes a winding mechanism and a grinding belt to clamp the spindle to be ground onto a three-jaw chuck. Starting the drive motor rotates the three-jaw chuck and the spindle, pushing the vertical arm closer to the spindle, bringing the grinding belt into contact with the rotating spindle. With the support of a support component, the grinding belt is ground using the friction between the belt and the spindle. In this structure, turning the rotating handles in the two winding mechanisms allows the grinding belt to be wound from one winding roller to the other.

Therefore, after replacing the grinding belt once, multiple spindles can be ground, and each spindle can be ground using the unused portion of the grinding belt, ensuring effective grinding. Furthermore, the used grinding belt can be wound up for easy recycling, making this a more rational and practical design.

[0014] This invention adjusts the base setting and activates the second electric push rod to push the first slide block to slide along the guide groove, thereby adjusting the position of the grinding belt on the spindle. Activating the first electric push rod to move the second slide block can adjust the distance between the grinding belt and the spindle, as well as the friction force. The structure is flexible and highly operable. Attached Figure Description

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0022] A grinding device for spindle production, such as Figure 1 - Figure 5 As shown, the system includes a base 1. A clamping mechanism for mounting and rotating the spindle is mounted on one side of the top of the base 1. The clamping mechanism includes a fixed base 2 vertically fixed to the base 1, a three-jaw chuck 3 rotatably mounted on the top of the fixed base 2 facing the center of the base 1, and a drive motor 4 mounted on the fixed base 2 for rotating the three-jaw chuck 3. The spindle to be polished is clamped on the three-jaw chuck 3, and then the drive motor 4 is started to rotate the three-jaw chuck 3 and the spindle to be polished, entering the polishing state. A vertical arm 6 is vertically arranged on the other side of the top of the base 1. A winding mechanism 7 is mounted on the top and bottom of the vertical arm 6 facing the clamping mechanism. A polishing belt 8 for polishing is wound between the two winding mechanisms 7. Pushing the vertical arm 6 closer to the spindle causes the polishing belt 8 to contact the rotating spindle. The friction between the polishing belt 8 and the spindle allows for polishing of the spindle.

[0023] In this embodiment, the winding mechanism 7 includes a fixed frame 18 fixed on the vertical arm 6 and a winding roller 19 rotatably mounted on the fixed frame 18. One end of the fixed frame 18 is equipped with a rotating handle 21 coaxially connected to the winding roller 19. A ratchet 20 is installed between the rotating handle 21 and the connecting shaft of the winding roller 19. By turning the rotating handle 21 in the two sets of winding mechanisms 7, the polishing belt 8 can be wound from the winding roller 19 in one set of winding mechanisms 7 toward the winding roller 19 in another set of winding mechanisms 7. The ratchet 20 in the two sets of winding mechanisms 7 can lock and position the winding roller 19 axially. Thus, after replacing the polishing belt 8 once, it can be used for polishing multiple spindles. Each spindle can be adjusted to use the unused part of the polishing belt 8 for polishing, ensuring the polishing effect of the spindle. It can also be used to wind up the waste polishing belt 8 after polishing for easy recycling.

[0024] In a further embodiment, a support member 9 is provided between the two sets of winding mechanisms 7 to support the grinding belt 8 away from the vertical arm 6. The support member 9 includes a fixed sleeve 22 that is vertically fixed to the side of the vertical arm 6 facing the grinding belt 8 and a support rod 23 that is movably inserted through the end of the fixed sleeve 22. A U-shaped bracket 24 is fixed to one end of the support rod 23 that extends out of the fixed sleeve 22. A support roller 25 is rotatably installed inside the U-shaped bracket 24. A baffle 26 is provided at one end of the support rod 23 that extends into the fixed sleeve 22. A spring 27 is provided between the baffle 26 and the end face of the fixed sleeve 22 facing the vertical arm 6. The elastic force of the spring 27 in the two sets of support members 9 on the support rod 23 enables a pair of support rollers 25 to push the grinding belt 8 to be elastically tightened, which is beneficial for the grinding belt 8 to contact the rotating spindle for grinding.

[0025] In a further embodiment, the base 1 is further provided with an adjusting base 5 for driving the vertical arm 6 to move laterally and longitudinally. The adjusting base 5 includes a first slide 11 slidably mounted on the upper surface of the base 1 and a second slide 12 slidably mounted on the top of the first slide 11. The vertical arm 6 is vertically fixed on the second slide 12. A reinforcing plate 28 is fixedly connected between the upper surface of the second slide 12 and the side wall of the vertical arm 6. A first electric push rod 15 is mounted on the first slide 11. The telescopic end of the first electric push rod 15 is connected to the second slide 12. A second electric push rod 17 is mounted on the base 1. The telescopic ends of the second electric push rod 17 are connected to the first slide block 11. The second electric push rod 17 and the first electric push rod 15 are vertically distributed. The first slide block 11 and the first electric push rod 15 are distributed along a direction perpendicular to the central axis of the three-jaw chuck 3. The second electric push rod 17 is distributed perpendicular to the first slide block 11. With this structure, starting the second electric push rod 17 pushes the first slide block 11 to slide along the guide groove 10, which can adjust the position of the grinding belt 8 on the spindle. Starting the first electric push rod 15 drives the second slide block 12 to move, which can adjust the distance between the grinding belt 8 and the spindle, as well as the friction force.

[0026] In this embodiment, a guide groove 10 is provided on the base 1, and the guide groove 10 is distributed perpendicular to the first slide block 11. A slider 16 is provided at the bottom of the first slide block 11, which is slidably engaged with the guide groove 10, which is beneficial to the sliding adjustment of the first slide block 11. A sliding groove 13 is provided on the upper surface of the first slide block 11, and the second slide block 12 is slidably engaged with the sliding groove 13. Two sliding rods 14 are fixed side by side in the sliding groove 13, and the sliding rods 14 move through the second slide block 12, which is beneficial to the sliding and translation of the second slide block 12.

[0027] The working principle of this utility model is as follows: In use, the spindle to be ground is clamped on the three-jaw chuck 3. Then, the drive motor 4 is started to rotate the three-jaw chuck 3 and the spindle to be ground. Subsequently, the first electric push rod 15 is activated to drive the second slide block 12 to slide along the slide groove 13. The second slide block 12, carrying the vertical arm 6, drives the grinding belt 8 to contact the rotating spindle. With the support member 9 supporting the grinding belt 8, the friction between the grinding belt 8 and the spindle is used to grind the spindle. By activating the second electric push rod 17 to push the first slide block 11 to slide along the guide groove 10, the position of the grinding belt 8 on the spindle can be adjusted. The structure is flexible and can... This structure offers high operability. By turning the rotating handle 21 in the two sets of winding mechanisms 7, the grinding belt 8 can be wound from the winding roller 19 in one set of winding mechanisms 7 towards the winding roller 19 in the other set of winding mechanisms 7. The ratchet 20 in the two sets of winding mechanisms 7 can lock and position the winding roller 19 axially. Thus, after replacing the grinding belt 8 once, it can be used for grinding multiple spindles. Moreover, each spindle can be adjusted to use the unused portion of the grinding belt 8 for grinding, ensuring the grinding effect of the spindle. Furthermore, the used grinding belt 8 can be wound up after grinding for easy recycling, making it more reasonable and practical.
