[0002] In current parts processing, the edges of parts often have burrs due to limitations in the processing technology. Burrs can affect product performance and, in severe cases, lead to devastating consequences. Currently, methods for removing burrs during processing include adding a deburring program to the processing flow, using chamfering and then reprocessing to remove the burrs. However, this method results in inconsistent surface quality after deburring. Another method utilizes devices similar to grinding shafts to handle burrs.

[0003] Patent application number 202321524222.4 discloses a portable grinding spindle device, including a drive assembly, a spindle connected to the drive assembly, a housing surrounding the spindle, a front cover for limiting the spindle at the front end of the housing, an elastic limiting assembly on the spindle, a span adjustment assembly surrounding the spindle, a secondary angular contact ball bearing at the front end of the span adjustment assembly, a primary angular contact ball bearing at the rear end of the span adjustment assembly, a mechanical seal assembly distributed on the secondary angular contact ball bearing, and a locking nut at the rear end of the primary angular contact ball bearing, the locking nut being sleeved on the spindle.

[0004] The above technical solution uses a grinding block installed on the drive equipment to grind the main body. However, due to the lack of positioning of the spindle, the spindle has poor stability during the processing. At the same time, due to the difficulty in controlling the grinding force and position of the grinding block, the grinding effect on the spindle is poor. Utility Model Content

[0005] Based on this, the purpose of this utility model is to provide a spindle machining device to solve the technical problems of poor spindle stability during machining due to lack of spindle positioning, and poor grinding effect of spindle due to difficulty in controlling the grinding force and position of the grinding block.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a spindle machining device, comprising a mounting frame and a spindle body disposed above the mounting frame, wherein movable frames are symmetrically arranged on one side of the top surface of the mounting frame, and a lifting grinding block tightly connected to the spindle body is disposed on the other side of the top surface of the mounting frame, a driving mechanism is disposed between the two movable frames, and telescopic plates are symmetrically and elastically inserted at both ends of the two movable frames, and a roller for driving the spindle body to rotate is rotatably disposed between the two telescopic plates on the same side.

[0007] The present invention is further configured such that a plurality of fastening bolts are embedded in a rectangular array on one side of the top surface of the mounting bracket, and the top of the mounting bracket is symmetrically provided with sliding grooves.

[0008] The present invention is further configured such that the driving mechanism includes a double-threaded screw rotatably disposed between two slide grooves and a fastening motor fixed to the side wall of the mounting bracket, wherein the shaft of the fastening motor is fixedly connected to the double-threaded screw.

[0009] The present invention is further configured such that the bottom ends of the two movable frames are each fixed with a sliding part that is slidably inserted into the sliding groove, and the two ends of the double threaded screw are respectively threaded into the two sliding parts.

[0010] The present invention is further configured such that a fixed seat is provided at the top of the mounting frame, the bottom end of the lifting grinding block is fitted into the fixed seat, and the top of the lifting grinding block is provided with an arc-shaped grinding groove that fits against the outer wall of the main shaft body.

[0011] The present invention is further configured such that an adjusting bolt is rotatably engaged at the bottom end of the mounting bracket, a screw hole is provided at the bottom end of the lifting grinding block, and the top end of the adjusting bolt extends into the fixed seat and is threaded into the screw hole.

[0012] The present invention is further configured such that springs are embedded in both ends of the movable frame, and the telescopic plate is inserted into one end of the movable frame and abuts against the springs.

[0013] The present invention is further configured such that both ends of the roller are equipped with mounting shafts that are rotatably inserted into the telescopic plate, and the side wall of the telescopic plate is fixed with a steering motor for driving the roller to rotate.

[0014] In summary, this utility model has the following advantages: By providing movable frames on both sides of the top surface of the mounting frame, the fastening motor drives the two movable frames to move towards each other after startup, causing the rollers on the movable frames to clamp and fix the main shaft body. During the fixing process, the telescopic plate slides within the movable frame, compressing the spring during sliding. As the spring continues to deform, the pressure between the rollers and the main shaft body increases until the protrusion at the bottom of the telescopic plate abuts against the inner wall of the top of the fixed seat and remains stable. The rollers on the movable frame facilitate clamping and fixing the main shaft body, improving the stability of the main shaft grinding. Furthermore, by installing a steering motor on the side wall of the telescopic plate, the steering motor drives one of the rollers to rotate via the mounting shaft, causing the clamped main shaft body to rotate synchronously during rotation. After rotation, the adjusting bolt drives the lifting grinding block to rise in the fixed seat, causing the arc-shaped grinding groove to abut against the main shaft body. Through the rotation of the main shaft body and its contact with the lifting grinding block, the rotating main shaft body can be fully ground, improving the grinding effect of the main shaft.

[0020] 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.

[0021] A spindle machining apparatus, such as Figures 1-4 As shown, the device includes a mounting frame 1 and a main spindle body 5 disposed above the mounting frame 1. A movable frame 6 is symmetrically arranged on one side of the top surface of the mounting frame 1, and a lifting grinding block 11 tightly connected to the main spindle body 5 is arranged on the other side of the top surface of the mounting frame 1. A drive mechanism is provided between the two movable frames 6, and telescopic plates 17 are symmetrically and elastically inserted at both ends of the two movable frames 6. A roller 15 for driving the main spindle body 5 to rotate is rotatably arranged between the two telescopic plates 17 on the same side.

[0022] The top surface of the mounting bracket 1 has multiple fastening bolts 2 embedded in a rectangular array on one side, and the top of the mounting bracket 1 has symmetrically opened sliding grooves 8. In use, one side of the mounting bracket 1 is fixed to the tabletop by the fastening bolts 2, and the other side of the mounting bracket 1 protrudes from the side wall of the tabletop. When the arc-shaped grinding groove 13 of the lifting grinding block 11 wears, the height of the lifting grinding block 11 can be adjusted by rotating the adjusting bolt 10 from the bottom of the mounting bracket 1. The drive mechanism includes a double-threaded screw 9 rotatably disposed between the two sliding grooves 8 and a fastening motor 3 fixed to the side wall of the mounting bracket 1. The shaft of the fastening motor 3 is fixedly connected to the double-threaded screw 9. The bottom ends of the two movable brackets 6 are each fixed with a sliding part 7 that slides into the sliding groove 8. Both ends of the threaded screw 9 are threaded into the two sliding parts 7 respectively. The top of the mounting frame 1 is provided with a fixed seat 4. The bottom end of the lifting grinding block 11 is fitted into the fixed seat 4. The top of the lifting grinding block 11 is provided with an arc-shaped grinding groove 13 that fits against the outer wall of the main shaft body 5. After the fastening motor 3 is started, it drives the two moving frames 6 to move towards each other, so that the roller 15 on the moving frame 6 clamps and fixes the main shaft body 5. During the fixing process, the telescopic plate 17 slides in the moving frame 6 and compresses the spring 14 to deform. During the continuous deformation of the spring 14, the compressive force between the roller 15 and the main shaft body 5 also increases until the protrusion at the bottom of the telescopic plate 17 abuts against the inner wall at the top of the fixed seat 4 and remains stable.

[0023] Furthermore, the bottom end of the mounting bracket 1 is rotatably engaged with an adjusting bolt 10, and the bottom end of the lifting grinding block 11 is provided with a screw hole 12. The top end of the adjusting bolt 10 extends into the fixed seat 4 and is threaded into the screw hole 12. The lifting grinding block 11 is made of non-rigid grinding material, and will undergo slight deformation when squeezed by the main shaft body 5, thereby avoiding the situation where the friction between the lifting grinding block 11 and the main shaft body 5 is too large and cannot rotate. Both ends of the movable frame 6 are embedded with springs 14, and the telescopic plate 1 7 is inserted into one end of the movable frame 6 and abuts against the spring 14. Both ends of the roller 15 are equipped with mounting shafts 18 that are rotatably inserted into the telescopic plate 17. The side wall of the telescopic plate 17 is fixed with a steering motor 16 for driving the roller 15 to rotate. After the adjusting bolt 10 rotates, it drives the lifting grinding block 11 to rise in the fixed seat 4, so that the arc-shaped grinding groove 13 abuts against the main shaft body 5. Through the rotation of the main shaft body 5 and contact with the lifting grinding block 11, the rotating main shaft body 5 can be fully ground.

[0024] The working principle of this utility model is as follows: During use, the main shaft body 5 is held and moved between the two movable frames 6. After the fastening motor 3 is started, it drives the two movable frames 6 to move towards each other, causing the rollers 15 on the movable frames 6 to clamp and fix the main shaft body 5. During this fixing process, the telescopic plate 17 slides within the movable frame 6, compressing the spring 14 and causing it to deform. As the spring 14 continues to deform, the pressure between the rollers 15 and the main shaft body 5 also increases until the protrusion at the bottom of the telescopic plate 17 abuts against the inner wall of the top of the fixed base 4. After connection, the main shaft body 5 is kept stable. The rollers on the movable frame 6 facilitate clamping and fixing of the main shaft body 5. The steering motor 16 is started to drive one of the rollers 15 to rotate through the mounting shaft 18. During the rotation, the clamped main shaft body 5 rotates synchronously. After the adjustment bolt 10 rotates, it drives the lifting grinding block 11 to rise in the fixed seat 4, so that the arc-shaped grinding groove 13 abuts against the main shaft body 5. Through the rotation of the main shaft body 5 and the contact of the lifting grinding block 11, the rotating main shaft body 5 can be fully ground, improving the grinding effect of the main shaft.
