Description

Technical Field

[0001] This utility model relates to the field of shaft polishing technology, specifically to an auxiliary fixing device for polishing stainless steel shafts. Background Technology

[0002] Stainless steel shafts refer to shafts made of stainless steel, primarily used in various mechanical equipment and industrial applications. The selection of stainless steel shafts is usually based on environmental and application requirements. Common types include 304 stainless steel, 316 stainless steel, and 430 stainless steel. Stainless steel shafts offer high cost-effectiveness and a wide range of applications, with good corrosion resistance. They are commonly used in mechanical equipment parts, chemical equipment, pharmaceutical equipment, food processing equipment, and textile equipment. During processing, stainless steel shafts require surface polishing before being secured.

[0003] In the prior art, the stainless steel auxiliary fixing device used to fix the stainless steel shaft is prone to relative slippage during the polishing process, which leads to incomplete polishing of some parts of the stainless steel shaft surface. In addition, the auxiliary fixing device used in the prior art requires the staff to manually adjust the polishing surface after the stainless steel shaft is fixed in order to complete the surface processing of the stainless steel shaft. Manual adjustment is highly subjective and the surface processing accuracy of the stainless steel shaft is low. Utility Model Content

Detailed Implementation

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, in this embodiment, an auxiliary fixing device for polishing stainless steel shafts includes a mounting base 1. Two sets of symmetrically distributed first adjusting rods 2 are slidably mounted inside the mounting base 1. Second adjusting rods 3 are slidably mounted inside each set of first adjusting rods 2. Two sets of symmetrically distributed mounting brackets 4 are provided on both sides of the mounting base 1. The two sets of mounting brackets 4 are respectively fixedly connected to the corresponding two sets of second adjusting rods 3. A fixing seat 5 is provided on the mounting bracket 4. A first turntable 8 and a second turntable 13 are rotatably mounted inside the fixing seat 5. The first turntable 8 and the second turntable 13 are movably sleeved. First annular teeth 11 and second annular teeth 16 are respectively fixedly mounted on the first turntable 8 and the second turntable 13. Three sets of annularly distributed first sliders 12 and second sliders 17 are provided on the fixing seat 5. Both slider 12 and the second slider 17 are fixedly mounted with clamping rods 18, and suction cups 22 are fixedly mounted on clamping rods 18. An adjusting tube 20 is provided inside the clamping rod 18, and the adjusting tube 20 is slidably connected to the clamping rod 18 via an oil groove 19. A third toothed ring 6 is provided on the fixed seat 5, and a bidirectional threaded rod 23 is rotatably mounted inside the mounting seat 1. Threaded tubes 24 are rotatably mounted inside both sets of first adjusting rods 2. Corresponding cylinders drive the sliding of the first rack 10 and the second rack 15 respectively, coordinating with the counter-rotation of the first toothed ring 9 and the second toothed ring 14, thereby causing the first annular tooth 11 and the second annular tooth 16 to rotate accordingly. Under the limiting action of the fixed seat 5, the clamping rods 18 on the three sets of first sliders 12, the three sets of second sliders 17, and the first sliders 12 and the second sliders 17 are all rotated. 8. Simultaneously move inward or outward to initially fix the inner and outer walls of the shaft material to be fixed. A first toothed ring 9 is sleeved on the first turntable 8, and a second toothed ring 14 is sleeved on the second turntable 13. A first rack 10 and a second rack 15 are slidably installed in the fixed seat 5. The first rack 10 is engaged with the first toothed ring 9, and the second rack 15 is engaged with the second toothed ring 14. The first slider 12 and the second slider 17 are correspondingly arranged. All three sets of first sliders 12 and second sliders 17 are slidably connected to the fixed seat 5. The three sets of first sliders 12 are engaged with the first turntable 8 through the first ring tooth 11, and the three sets of second sliders 17 are engaged with the second turntable 13 through the second ring tooth 16. An oil groove 19 is opened in the clamping rod 18. The screw 21 has two ends that pass through and are rotatably connected to the clamping rod 18. The screw 21 also passes through and is threadedly connected to the adjusting tube 20. After the clamping rod 18 installed on the first slider 12 and the second slider 17 and the suction cup 22 on the clamping rod 18 complete the initial fixation of the shaft, the motors inside the clamping rod 18 of the first slider 12 and the second slider 17 are started to drive the screw 21 to rotate. Under the limiting action of the clamping rod 18, the adjusting tube 20 slides inside the clamping rod 18, squeezing the hydraulic oil in the oil groove 19. This causes the clamping rod 18 on the first slider 12 and the second slider 17 to expand to a certain extent, strengthening the fixation strength of the shaft. During the polishing process of the shaft, there will be no slippage that would cause displacement or deviation of the machined surface.

[0024] like Figure 2 and Figure 5 As shown, the fixed seat 5 is rotatably connected to the mounting frame 4 via bearings. The mounting frame 4 is equipped with a drive wheel 7, which is rotatably connected to the mounting frame 4 via a rotating shaft. The drive wheel 7 is meshed with the third toothed ring 6. After the two sets of fixed seats 5 have completed the fixing of the shaft material, the polishing work on the surface of the shaft material begins. During the polishing process, the motor on the mounting frame 4 is started to drive the drive wheel 7 to rotate. This, in conjunction with the third toothed ring 6, causes the fixed seat 5 to drive the shaft material to rotate at a uniform speed on the mounting frame 4, thus completing the automatic adjustment of the machined surface of the shaft material. The two ends of the bidirectional screw 21 pass through two sets of first adjusting rods 2 and are threadedly connected to the two sets of first adjusting rods 2 respectively. The two sets of threaded tubes 24 pass through the corresponding second adjusting rods 3 and are threadedly connected to the corresponding second adjusting rods 3 respectively. The bidirectional threaded rod 23 has two sets of symmetrically distributed slots 25, and the threaded tubes 24 have two sets of symmetrically distributed locking blocks 26. The locking block 26 and the locking slot 25 are correspondingly set. The threaded tube 24 is slidably sleeved with the bidirectional threaded rod 23 through the locking block 26. The bidirectional threaded rod 23 is sleeved with a first bevel gear 27. The mounting base 1 is provided with a second bevel gear 28. The second bevel gear 28 is rotatably connected to the mounting base 1 through a rotating shaft. The second bevel gear 28 is meshed with the first bevel gear 27. When the motor in the mounting base 1 drives the second bevel gear 28 to rotate, it cooperates with the first bevel gear 27 to make the bidirectional threaded rod 23 rotate. Under the limiting action of the mounting base 1, the two sets of first adjusting rods 2 slide synchronously inward or outward. Under the action of the locking block 26 and the locking slot 25, the threaded tube 24 rotates synchronously with the bidirectional threaded rod 23. Under the action of the first limiting rod, the second adjusting rod 3 slides in the first adjusting rod 2, realizing the adjustment of the distance between the two sets of mounting brackets 4, so that the fixing device can be used to fix different types of shaft materials.

[0025] This utility model provides an auxiliary fixing device for polishing stainless steel shafts. The specific working principle is as follows: Corresponding cylinders drive the sliding of the first rack 10 and the second rack 15, coordinating with the counter-rotation of the first gear ring 9 and the second gear ring 14. This causes the first ring tooth 11 and the second ring tooth 16 to rotate accordingly. Under the limiting action of the fixing seat 5, the three sets of first sliders 12 and three sets of second sliders 17, as well as the clamping rods 18 on the first sliders 12 and the second sliders 17, move synchronously inward or outward, completing the initial fixing of the inner and outer walls of the shaft to be fixed. After the initial fixing of the shaft is completed, the clamping rods 18 installed on the first sliders 12 and the second sliders 17, and the suction cups 22 on the clamping rods 18, respectively activate the motors inside the clamping rods 18 of the first sliders 12 and the second sliders 17, driving the screw 21 to rotate. Under the limiting action of the clamping rods 18, the adjusting tube 20 slides within the clamping rods 18, squeezing the hydraulic oil in the oil groove 19, causing the clamping rods 12 and the second sliders 17 to rotate. All rods 18 expand to a certain extent, strengthening the fixing strength of the shaft material. During the polishing process, slippage will not occur, causing displacement and deviation of the machined surface. After the two sets of fixing seats 5 have completed the fixing of the shaft material, the polishing work on the surface of the shaft material begins. During the polishing process, the motor on the mounting frame 4 is started to drive the drive wheel 7 to rotate. In conjunction with the third gear ring 6, the fixing seat 5 drives the shaft material to rotate at a uniform speed on the mounting frame 4, completing the automatic adjustment of the machined surface of the shaft material. When the motor in the mounting seat 1 drives the second bevel gear 28 to rotate, it cooperates with the first bevel gear 27 to make the bidirectional threaded rod 23 rotate. Under the limiting action of the mounting seat 1, the two sets of first adjusting rods 2 slide synchronously inward or outward. Under the action of the locking block 26 and the locking groove 25, the threaded tube 24 rotates synchronously with the bidirectional threaded rod 23. Under the action of the first limiting rod, the second adjusting rod 3 slides in the first adjusting rod 2, realizing the adjustment of the distance between the two sets of mounting frames 4, so that the fixing device can be used to fix different types of shaft materials.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
