DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-4 The utility model provides a technical solution: a thrust ring inner hole polishing device, including a polishing frame 1 and a base 2, the base 2 is fixed to the lower end of the polishing frame 1, the left and right sides of the bottom end of the polishing frame 1 are fixed with guide shafts 3, the outer periphery of the guide shafts 3 are slidably sleeved with support platforms 4, the outer side of the upper end of the support platforms 4 are fixed with guide rods 5, the outer periphery of the guide rods 5 are slidably sleeved with pressure plates 6, the top end of the polishing frame 1 is fixed with an electric cylinder 9, and a clamping position adjustment component is provided below the electric cylinder 9. The tight position adjustment assembly includes a fixed plate 10, a telescopic ruler 11, an adjustment plate 7 and a bidirectional threaded adjustment rod 8. The fixed plate 10 is connected to the power end of the electric cylinder 9. The telescopic ruler 11 is provided with two and is fixed one by one to the left and right ends of the fixed plate 10. The adjustment plate 7 is provided with two pieces and is fixed one by one to the upper ends of the two pressure plates 6. The ends of the telescopic ruler 11 are connected to the adjacent adjustment plates 7. The bidirectional threaded adjustment rod 8 passes through the adjustment plate 7 from left to right through the thread. Handles are fixed to the left and right ends of the bidirectional threaded adjustment rod 8.

[0026] When the inner hole of the thrust ring is polished by the polishing equipment, the distance between the two support platforms 4 is first adjusted according to the size of the thrust ring, so the handle is held and the two-way threaded adjustment rod 8 is turned to drive the two adjustment plates 7 to move closer or farther away from each other. During this process, the adjustment plate 7 will pull the pressure plate 6, the guide rod 5 and the support platform 4 to move back and forth, and the support platform 4 will slide along the guide shaft 3. At this time, the distance between the two support platforms 4 will increase or decrease. At the same time, the adjustment plate 7 will stretch or compress the telescopic ruler 11 when moving left and right, and then according to the scale value on the telescopic ruler 11, it is convenient to accurately adjust the support distance between the two support platforms 4. Therefore, by adjusting the support distance between the two support platforms 4, it is beneficial to support thrust rings with various inner hole sizes.

[0027] In this embodiment, a vacuum cleaner 14 is fixed in the base 2, and the dust suction port of the vacuum cleaner 14 is rotatably connected and communicated with the shaft tube 12. The shaft tube 12 rotates upward and penetrates into the polishing frame 1. Synchronous electric telescopic shafts 18 are fixed on both sides of the shaft tube 12. The power ends of the synchronous electric telescopic shafts 18 are connected to polishing rollers 13. The outer side of the shaft tube 12 is connected to a battery 23, and the battery 23 is connected in series with the synchronous electric telescopic shaft 18.

[0028] And a plurality of thrust rings are stacked and sleeved on the outer periphery of the two polishing rollers 13. After the support platform 4 supports the thrust ring, the synchronous electric telescopic shaft 18 is powered by the battery 23. After the synchronous electric telescopic shaft 18 is extended, it will drive the two polishing rollers 13 to move outward at the same time until the two polishing rollers 13 are in contact with the inner hole wall of the thrust ring at the same time. Moreover, the thrust ring is pushed by the polishing roller 13, which is conducive to quickly aligning and positioning the thrust ring to avoid deviation of the polishing roller 13 when polishing the inner hole of the thrust ring, which is conducive to ensuring the polishing accuracy. Moreover, the extension of the electric cylinder 9 drives the fixed plate 10, the telescopic ruler 11, the adjustment plate 7 and the pressure plate 6 to move downward together, and the pressure plate 6 slides down along the guide rod 5 until the pressure plate 6 presses the thrust ring on the support platform 4, so that the plurality of thrust rings can be quickly and conveniently pressed and fixed to avoid loosening of the thrust ring during polishing.

[0029] In this embodiment, a rotation drive assembly is provided under the polishing frame 1, and the rotation drive assembly includes a motor 15, a main gear 16 and a sub gear 17. The motor 15 is fixed to the lower end of the polishing frame 1, the main gear 16 is connected to the power end of the motor 15, and the sub gear 17 is fixedly sleeved on the outer periphery of the shaft tube 12, and the main gear 16 is meshed with the sub gear 17.

[0030] Then, the motor 15 drives the main gear 16, the sub-gear 17, the shaft tube 12, the synchronous electric telescopic shaft 18, and the polishing roller 13 to rotate together. The two polishing rollers 13 will polish the inner hole wall of the thrust ring at the same time, and multiple thrust rings are stacked together, so it is beneficial to polish the inner hole walls of multiple thrust rings at the same time. Compared with the single polishing process of the thrust ring in the prior art, it is beneficial to effectively improve the polishing efficiency of the thrust ring.

[0031] In this embodiment, two telescopic rods 22 are connected between the polishing roller 13 and the shaft tube 12 and are distributed vertically.

[0032] When the polishing roller 13 is pushed outward by the synchronous electric telescopic shaft 18, the polishing roller 13 will stretch the telescopic rod 22 at the same time, which is beneficial to ensure the stability of the polishing roller 13 when moving. In addition, when the polishing roller 13 is polishing the inner hole of the push ring, the telescopic rod 22 is connected between the shaft tube 12 and the polishing roller 13, which is beneficial to prevent the occurrence of insufficient stress on the synchronous electric telescopic shaft 18 for the polishing roller 13.

[0033] In this embodiment, a vacuum cleaner 14 is fixed in the base 2, and the dust suction port of the vacuum cleaner 14 is rotatably connected and communicated with the shaft tube 12, and the shaft tube 12 rotates upward and penetrates into the polishing frame 1, and synchronous electric telescopic shafts 18 are fixed on both sides of the shaft tube 12, and the power ends of the synchronous electric telescopic shafts 18 are connected to polishing rollers 13, and dust suction pipes 20 are fixed at the front and rear ends of the polishing rollers 13. The outsides of the dust suction pipes 20 are connected to a plurality of dust hoods 21, and two telescopic pipes 19 are connected between the dust suction pipes 20 and the shaft tube 12.

[0034] Moreover, when the polishing roller 13 is polishing the inner hole wall of the thrust ring, the rotation of the shaft tube 12 will drive the telescopic tube 19, the polishing roller 13, the dust suction tube 20 and the dust suction hood 21 to rotate together, and multiple dust suction hoods 21 are set at the front and rear ends of each polishing roller 13. Therefore, the dust generated by the polishing roller 13 during polishing will be absorbed by the dust suction hood 21 at the first time, and the dust will be absorbed into the dust collector 14 by the dust suction tube 20, the telescopic tube 19 and the shaft tube 12, thereby preventing the dust from flying and polluting the working environment, and reducing the trouble of cleaning and collecting dust in the later stage, making the polishing work of the thrust ring easier.

[0035] Working principle:

[0036] A plurality of thrust rings are stacked and sleeved on the outer periphery of the two polishing rollers 13, and then the electric telescopic shaft 18 is extended to drive the two polishing rollers 13 to contact the inner hole wall of the thrust ring at the same time, and the fixed plate 10, the telescopic ruler 11, the adjustment plate 7 and the pressure plate 6 are moved downward together by the extension of the electric cylinder 9, and the pressure plate 6 slides down along the guide rod 5 until the pressure plate 6 presses the thrust ring on the support platform 4, and then the main gear 16, the sub-gear 17, the shaft tube 12, the synchronous electric telescopic shaft 18, and the polishing roller 13 are driven to rotate together by the operation of the motor 15, and the two polishing rollers 13 will polish the inner hole wall of the thrust ring at the same time, and the vacuum cleaner 14 starts to work, so the dust generated during the polishing of the polishing roller 13 will be absorbed by the dust hood 21 at the first time, and finally the dust is absorbed into the vacuum cleaner 14 by the dust suction pipe 20, the telescopic tube 19 and the shaft tube 12.
