Description
Technical Field
[0001] This utility model relates to a double-headed grooving mechanism for steering gear steel pipes, belonging to the technical field of steering gear steel pipe milling equipment. Background Technology
[0002] One important component in automotive steering systems is the steering gear tube. The steering gear tube is round, and to fit the steering gear, rectangular slots are usually cut at both ends of the steering gear tube to accommodate the steering gear assembly.
[0003] Currently, the rectangular grooves in steering gear steel pipes are mainly cut manually using a cutter to grind and cut a rectangular groove along the circumference of one end of the steel pipe. After cutting, the end of the steel pipe is turned around, and a rectangular groove is cut again along the circumference of the other end. This cutting method is not only labor-intensive and inefficient, but also prone to mismatches in the cutting positions of the rectangular grooves at both ends of the steel pipe due to individual differences among workers, which directly affects the yield rate of steering gears. Therefore, it is necessary to improve this method. Summary of the Invention
[0004] The purpose of this utility model is to provide a double-end grooving mechanism for steering gear steel pipes that effectively reduces manual labor intensity, improves grooving efficiency, and solves the problem of mismatched rectangular groove cutting positions at both ends of the steering gear steel pipe in existing manual cutting methods.
[0005] The technical solution of this utility model is: A double-headed grooving mechanism for steering gear steel pipes includes a frame, a first cutting blade, a second cutting blade, and a lifting plate. The lifting plate is slidably mounted on the frame via a first guide rod. A lower positioning block is mounted on the lifting plate. An upper clamping block is slidably mounted on the lifting plate on one side of the lower positioning block via a mounting plate and a second guide rod. A locking screw is movably mounted on the upper clamping block and threadedly connected to the mounting plate. A handle is mounted at the top of the locking screw. A first cutting blade is movably mounted on the frame on one side of the handle via a first rotating shaft. A second cutting blade is movably mounted on the frame on one side of the handle via a second rotating shaft. A lifting cylinder is provided at the bottom of the lifting plate, and the piston rod of the lifting cylinder is fixedly connected to the lifting plate.
[0006] The lifting plate is a rectangular plate, and a first guide hole is provided at each of the four corners of the lifting plate. The first guide hole is slidably connected with the first guide rod.
[0007] The lower positioning block is a rectangular strip, and a positioning groove is provided on the upper surface of the lower positioning block.
[0008] Limiting plates are fixedly mounted on the frame at the corresponding positions at both ends of the lower positioning block. The limiting plates are rectangular plates.
[0009] The upper pressing block is a rectangular strip, and a pressing groove is provided on the lower surface of the upper pressing block.
[0010] A first driven sprocket is fixedly mounted on the first rotating shaft, and a second driven sprocket and a third driven sprocket are spaced apart on the second rotating shaft. The first driven sprocket and the second driven sprocket are connected by a first transmission chain. A drive motor is mounted on the frame below the second rotating shaft via a motor mounting bracket. A drive sprocket is fixedly mounted on the drive shaft of the drive motor, and the third driven sprocket and the drive sprocket are connected by a second transmission chain.
[0011] The advantages of this utility model compared with the prior art are as follows: The double-grooved steering gear tube mechanism positions the steering gear tube using the positioning groove of the lower positioning block, while the limiting plate limits both ends of the tube, effectively ensuring the tube remains centered within the positioning groove of the lower positioning block. Rotating the handle rotates the locking screw, causing it to descend relative to the mounting plate. The second guide rod limits the upper clamping block, and with the movable connection between the locking screw and the upper clamping block via a movable seat, the upper clamping block descends axially along the locking screw without rotating synchronously with it, until its clamping groove contacts the circumference of the steering gear tube. The friction between the locking screw and the mounting plate, combined with the interplay between the clamping groove of the upper clamping block and the positioning groove of the lower positioning block, clamps the steering gear tube. After the steering gear steel pipe is clamped, the drive motor is started. The drive motor drives the first and second cutting blades to rotate through the first and second rotating shafts. The lifting cylinder is activated, and the piston rod of the lifting cylinder is extended outward. The outwardly extended piston rod can drive the lifting plate to rise. The lifting plate moves upward along the first guide rod. The upward movement of the lifting plate drives the upper clamping block, the lower positioning block and the steering gear steel pipe to rise synchronously. When the steering gear steel pipe contacts the first and second cutting blades, the first and second cutting blades cut a groove at the end of the steering gear steel pipe, thereby completing the grooving operation at both ends of the steering gear steel pipe. This double-head grooving mechanism for steering gear steel pipes effectively reduces the intensity of manual labor, improves the efficiency of grooving, and solves the problem of mismatched rectangular groove cutting positions at both ends of the steering gear steel pipe in existing manual cutting methods.

[0014] As attached Figure 1-4 As shown The double-headed grooving mechanism for steering gear steel pipe includes a frame 1, a first cutting blade 2, a second cutting blade 3, and a lifting plate 4. A first guide rod 5 is fixedly installed in an array on the frame 1, and a lifting plate 4 is slidably installed on the first guide rod 5. The lifting plate 4 is a rectangular plate, and a first guide hole is opened at each of the four corners of the lifting plate 4 corresponding to the position of the first guide rod 5. The first guide hole and the first guide rod 5 are slidably connected. During operation, the first guide rod 5 limits the lifting plate 4 through the first guide hole, and the lifting plate 4 can only move upward or downward along the axial direction of the first guide rod 5.
[0015] A lifting cylinder 6 is provided at the bottom of the lifting plate 4. The piston rod of the lifting cylinder 6 is fixedly connected to the lifting plate 4. During operation, the lifting plate 4 can be driven to rise or fall by the piston rod of the lifting cylinder 6.
[0016] A lower positioning block 7 is fixedly installed in the middle of the lifting plate 4. The lower positioning block 7 is a rectangular strip. A positioning groove 8 is provided on the upper surface of the lower positioning block 7. During operation, the positioning groove 8 cooperates with the circumference of the steering gear steel tube 24 to realize the positioning of the steering gear steel tube 24, and at the same time, it can prevent the steering gear steel tube 24 from rolling on the lower positioning block 7.
[0017] An installation plate 9 is fixedly installed on the lifting plate 4 on one side of the lower positioning block 7. A second guide rod 10 is symmetrically slidably installed on the installation plate 9. An upper clamping block 11 is fixedly installed at the bottom of the second guide rod 10. The upper clamping block 11 is a rectangular strip. A clamping groove 12 is provided on the lower surface of the upper clamping block 11. During operation, the clamping groove 12 can limit the steering gear steel pipe 24. The clamping groove 12 of the upper clamping block 11 and the positioning groove 8 of the lower positioning block 7 cooperate with each other to achieve the clamping of the steering gear steel pipe 24.
[0018] Limiting plates 13 are fixedly installed on the frame 1 at the corresponding positions at both ends of the lower positioning block 7. The limiting plates 13 are rectangular plates. During operation, the limiting plates 13 can be used to limit the ends of the steering gear steel pipe 24, effectively ensuring that the steering gear steel pipe 24 remains centered in the positioning groove 8 of the lower positioning block 7, which facilitates the subsequent simultaneous grooving operation at both ends.
[0019] A locking screw 14 is movably mounted on the upper clamping block 11 via a movable seat. The locking screw 14 is threadedly connected to the mounting plate 9. A handle 15 is fixedly mounted on the top of the locking screw 14. During operation, the handle 15 can drive the locking screw 14 to rotate, thereby causing the locking screw 14 to rotate upward or downward relative to the mounting plate 9. Through the limiting effect of the second guide rod 10 on the upper clamping block 11, and with the cooperation of the movable connection between the locking screw 14 and the upper clamping block 11 via the movable seat, the upper clamping block 11 can rise or fall along the axial direction of the locking screw 14 without rotating synchronously with the locking screw 14.
[0020] A first rotating shaft 16 is movably mounted on the frame 1 on one side of the handle 15 via a bearing. A first cutting blade 2 is fixedly mounted on the first rotating shaft 16. A second rotating shaft 17 is movably mounted on the frame 1 on one side of the handle 15 via a bearing. A second cutting blade 3 is fixedly mounted on the second rotating shaft 17.
[0021] A first driven sprocket 18 is fixedly mounted on the first rotating shaft 16. A second driven sprocket 19 and a third driven sprocket 20 are fixedly mounted on the second rotating shaft 17 at intervals. The first driven sprocket 18 and the second driven sprocket 19 are connected by a first transmission chain 21. A drive motor 25 is fixedly mounted on the frame 1 below the second rotating shaft 17 via a motor mounting bracket. A drive sprocket 22 is fixedly mounted on the drive shaft of the drive motor 25. The third driven sprocket 20 and the drive sprocket 22 are connected by a second transmission chain 23. During operation, the drive motor 25 drives the drive sprocket 22 to rotate via the drive shaft. The drive sprocket 22 drives the third driven sprocket 20 and the second rotating shaft 17 to rotate synchronously via the second drive chain 23. The second rotating shaft 17 drives the second driven sprocket 19 to rotate synchronously. The second driven sprocket 19 drives the first driven sprocket 18 and the first rotating shaft 16 to rotate synchronously via the first drive chain 21. Thus, the first cutting blade 2 and the second cutting blade 3 are driven to rotate via the first rotating shaft 16 and the second rotating shaft 17.
[0022] When using the double-ended grooving mechanism for steering gear steel pipes, first place the steering gear steel pipe 24 to be grouted into the positioning groove 8 of the lower positioning block 7, so that both ends of the steering gear steel pipe 24 abut against the limiting plate 13. The limiting plate 13 limits the ends of the steering gear steel pipe 24, effectively ensuring that the steering gear steel pipe 24 remains centered in the positioning groove 8 of the lower positioning block 7. By rotating the handle 15, the locking screw 14 can be rotated, thereby causing the locking screw 14 to rotate and descend relative to the mounting plate 9, and press against the upper pressing block 1 through the second guide rod 10. The limiting function of 1, with the cooperation of the movable connection between the locking screw 14 and the upper clamping block 11 through the movable seat, allows the upper clamping block 11 to descend along the axial direction of the locking screw 14 without rotating synchronously with it, until the clamping groove 12 of the upper clamping block 11 contacts the circumference of the steering gear steel tube 24. Under the friction between the locking screw 14 and the mounting plate 9, the clamping groove 12 of the upper clamping block 11 and the positioning groove 8 of the lower positioning block 7 cooperate to clamp the steering gear steel tube 24.
[0023] After the steering gear steel pipe 24 is clamped, the drive motor 25 is started. The drive shaft of the drive motor 25 drives the drive sprocket 22 to rotate. The drive sprocket 22 drives the third driven sprocket 20 and the second rotating shaft 17 to rotate synchronously through the second drive chain 23. The second rotating shaft 17 drives the second driven sprocket 19 to rotate synchronously. The second driven sprocket 19 drives the first driven sprocket 18 and the first rotating shaft 16 to rotate synchronously through the first drive chain 21. Thus, the first cutting blade 2 and the second cutting blade 3 are driven to rotate through the first rotating shaft 16 and the second rotating shaft 17.
[0024] Start the lifting cylinder 6, control the piston rod of the lifting cylinder 6 to extend outward, the outward extension of the piston rod can drive the lifting plate 4 to rise, the lifting plate 4 moves upward along the first guide rod 5, the upward movement of the lifting plate 4 drives the upper clamping block 11, the lower positioning block 7 and the steering gear steel pipe 24 to rise synchronously. When the steering gear steel pipe 24 contacts the first cutting blade 2 and the second cutting blade 3, the first cutting blade 2 and the second cutting blade 3 cut a groove at the end of the steering gear steel pipe 24. After cutting, control the piston rod of the lifting cylinder 6 to reset, then loosen the locking screw 14 to remove the cut steering gear steel pipe 24, and replace it with the next steering gear steel pipe 24 to be cut. In this way, the grooving operation of the steering gear steel pipe 24 can be repeated.
