Description

Technical Field

[0001] The invention relates to the technical field of motor shaft turning, and more specifically, to a turning device for producing motor shafts. Background Art

[0002] In the current motor shaft manufacturing field, turning is a key process to ensure the accuracy and quality of motor shafts. However, the existing motor shaft turning equipment has obvious technical defects in actual application, which is mainly reflected in the design of the support system. Traditional turning equipment usually supports the motor shaft by fixing both ends. However, since the turning process is a dynamic processing process with continuous movement, the fixed support frame cannot make corresponding adjustments as the tool moves. This not only increases the risk of deformation of the workpiece, but may also lead to a decrease in processing accuracy. Especially when processing long or thin shaft workpieces, the support problem in the middle position is more prominent.

[0003] More importantly, the lubrication problem of the existing support frame during operation also needs to be solved urgently. Due to the lack of an effective lubrication system, the friction between the support frame and the motor shaft will gradually increase with the extension of processing time, which will not only aggravate the wear of the workpiece surface, but also cause the temperature of the support frame itself to rise, affecting the processing accuracy. At the same time, insufficient lubrication will also accelerate the wear of the support frame, shorten the service life of the equipment, and increase maintenance costs. The design deficiencies of this support frame not only affect the production efficiency, but also cannot guarantee the stability of product quality. Summary of the invention

[0023] The overall working principle is: first, the motor shaft is installed on the lathe 1, and the two ends of the motor shaft are fixed respectively, and then the cylinders 4 on both sides are started. As the extended end of the cylinder 4 moves, the two bidirectional frames 6 will be driven to move in the same direction, and then the fixed plate 13 will move accordingly. First, the multiple balls 38 on the clamping seats 7 at both ends are respectively fitted on the side walls of the motor shaft, and then as the movement continues, the multiple semicircular blocks 36 will rotate along the clamping seats 7, so that the multiple balls 38 are stably stuck on the side walls of the motor shaft. At this time, the two clamping seats 7 will stop moving due to their mutual fit with the motor shaft, and then the support spring 19 is continuously compressed, and the guide rod 18 slides along the guide sleeve 17 until the clamping seat 7 is against the two guide sleeves 17. At this time, the fixing process is completed, and while stopping moving, the push rod 12 has been against the baffle 14, so the seal between the sealing disk 10 and the sealing sleeve 11 will be released. At this time, the side of the oil storage pipe 20 is against the closed groove 24, so the oil inlet pipe 21 is in a closed state. At this time, the oil storage pipe 20 and the oil outlet pipe 22 The movable sleeve 15 prevents the lubricating oil from flowing out at the other end. Since the air inlet pipe 35 is connected to the air pump, as the push rod 12 moves backward, the throttle plate 32 also moves backward, thereby releasing the seal between the throttle plate 32 and the partition plate 33. The gas enters between the oil storage pipe 20 and the piston 28 through the air inlet pipe 35, the sliding frame 34, the air inlet groove 31 and the through groove 30, and then applies pressure to the piston 28, and applies pressure to the lubricating oil in the oil storage pipe 20 through the piston 28, thereby pushing the lubricating oil to the Pushed from the outside, the lubricating oil flows into the semi-enclosed groove 39 through the oil outlet pipe 22, the hose 37 and the lubrication hole 40, and the ball 38 is lubricated by the lubricating oil. At this time, the lathe 1 has been started, and then multiple balls 38 rotate accordingly, and are lubricated by the lubricating oil. As the moving platform 2 turns the motor shaft, the ball 38 can not only rotate axially but also move with the movement of the moving platform 2. Therefore, the motor shaft can be dynamically supported as the moving platform 2 moves, thereby ensuring the processing accuracy.

[0024] In order to achieve continuous oil supply, add an oil inlet mechanism, please refer to Figures 4 to 10The oil inlet mechanism includes an oil storage pipe 20, an oil inlet pipe 21 and an oil outlet pipe 22. The oil storage pipe 20 is slidably connected in the side sleeve 8. The oil inlet pipe 21 is installed on the side wall of the side sleeve 8, and the oil inlet pipe 21 is at the upper end of the sealing sleeve 11. The side wall of the side sleeve 8 is connected and installed with an oil outlet pipe 22. The oil outlet pipe 22 is between the sealing sleeve 11 and the movable sleeve 15. An intermediate ring 23 is coaxially provided on the inner wall of the side sleeve 8, and a closed groove 24 is opened in the side sleeve 8. A segmented ring 25 is coaxially provided in the oil storage pipe 20. The segmented ring 25 is slidably connected in the side sleeve 8. The intermediate rod 9 is slidably connected in the oil storage pipe 20. A follower plate 26 is coaxially provided on the side wall of the oil storage pipe 20. A rotating sleeve 27 is provided on the inner thread of the side sleeve 8. The rotating sleeve 27 The rotating sleeve is connected to the follower plate 26, and the rotating sleeve 27 is rotatably connected to the outer wall of the oil storage tube 20. A piston 28 is slidably provided on the intermediate rod 9, and the piston 28 is slidably connected to the inner wall of the oil storage tube 20. An internal sleeve 29 is provided in the oil storage tube 20, and a plurality of through grooves 30 are equidistantly provided on the internal sleeve 29 along the axis. The intermediate rod 9 is slidably connected in the internal sleeve 29, and an air intake groove 31 is provided on the intermediate rod 9. A throttle plate 32 is provided on the intermediate rod 9. A partition plate 33 is coaxially provided in the oil storage tube 20, and the throttle plate 32 is slidably connected in the partition plate 33. A sliding frame 34 is coaxially provided on the throttle plate 32. An air intake pipe 35 is coaxially provided in the oil storage tube 20, and the air intake pipe 35 is connected to the oil storage tube 20, and the air intake pipe 35 is connected to the air pump.

[0025] Working principle: When there is lubricating oil in the oil storage pipe 20, the oil inlet pipe 21 needs to be closed. At this time, the rotating sleeve 27 is rotated so that the rotating sleeve 27 rotates along the thread of the side sleeve 8. Since the follower plate 26 is connected to the rotating sleeve 27, it will drive the rotating sleeve 27 to move in the direction of the oil inlet pipe 21, and the oil storage pipe 20 also moves in the same direction. Then the segmented ring 25 abuts against the closed groove 24, thereby sealing the oil inlet pipe 21. Then, as the push rod 12 presses on the baffle 14, the sealing disc 10 is untied and the space between the sealing sleeve 11 is The connection between the piston 28 and the oil storage pipe 20 is connected, and the movement of the piston 28 pushes the lubricating oil through the sealing sleeve 11 and the oil outlet pipe 22 to flow into the hose 37, thereby completing the lubrication process. When the lubricating oil needs to be replenished, the rotating sleeve 27 is driven to move toward the direction of the air inlet pipe 35, so that the segmented circle 25 abuts against the middle circle 23. At this time, the oil storage pipe 20 and the side sleeve 8 are in a sealed state, and then the lubricating oil is injected into the oil inlet pipe 21. Since the oil inlet pipe 21 is at the upper end, the oil storage pipe 20 can be filled, thereby completing the oil replenishment process.

[0026] See also Figure 11 to Figure 12In order to achieve effective fitting with the motor shaft, a fitting mechanism is added. The fitting mechanism includes a semicircular block 36, a hose 37 and a ball 38. The semicircular block 36 is rotatably connected in the clamping seat 7. A plurality of half-grooves 39 and lubrication holes 40 are provided on the semicircular block 36. Each lubrication hole 40 is connected to the hose 37. The lubrication hole 40 is connected to the half-groove 39. The other end of the hose 37 is connected to the oil outlet pipe 22. A ball 38 is rotatably installed in each half-groove 39.

[0027] Working principle: when the motor shaft needs to be fixed, as the two clamping seats 7 move toward the motor shaft at the same time, the ball 38 in the middle position first contacts the motor shaft, and at this time the semicircular block 36 rotates along the clamping seat 7, and then the ball 38 at the upper end also contacts the motor shaft, thereby completing the clamping process. Since the semicircular block 36 can rotate along the clamping seat 7, it can adapt to various types of motor shafts, thereby ensuring the versatility of the clamping, and the ball 38 can not only rotate with the rotation of the motor shaft, but also rotate when the movable table 2 moves. Therefore, as the movable table 2 is turned at different positions, the stability of use is guaranteed. As the ball 38 rotates, the lubricating oil can be filled in the entire semi-groove 39, and a layer of oil film is formed by the lubricating oil, thereby reducing the friction between the semi-groove 39 and ensuring the continuity of turning.

[0028] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which will not be described one by one here. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
