Description

Technical Field

[0001] The utility model relates to the technical field of positioning, in particular to a reaming positioning device based on a rack of a car safety belt. Background Art

[0002] Reaming is a method in which a reamer removes a trace amount of metal layer from the hole wall of a workpiece to improve its dimensional accuracy and hole surface quality. Reaming is one of the finishing methods for holes and is widely used in production. For smaller holes, reaming is a more economical and practical processing method compared to internal grinding and fine boring. When reaming a car seat belt rack, it is usually necessary to fix the rack through a positioning device so that the processing can be carried out smoothly.

[0003] During use, the existing positioning device can usually clamp and fix the rack through a cylinder, but in actual use, it can usually only fix the rack and cannot flip the rack according to processing requirements. It needs to be flipped manually, which is inconvenient to operate. For this reason, we propose a reaming positioning device based on the car seat belt rack. Utility Model Content

[0025] The working principle of the above technical solution is as follows:

[0026] During use, the clamping and flipping mechanism 6 can clamp and fix the rack. At the same time, when the rack needs to be flipped, the first electric telescopic rod 3 can be retracted, so that the lifting plate 4 moves downward and no longer lifts the rack. At this time, the clamping and flipping mechanism 6 can flip the rack. After the flipping is completed, the first electric telescopic rod 3 pushes the lifting plate 4 upward, so that the lifting plate 4 can stably lift the rack, so that the rack can be in a stable state for processing, which is easy to operate.

[0027] In another embodiment, if Figure 2 As shown, the clamping and flipping mechanism 6 includes a movable mounting base 9, a fixed through groove 10 is provided at the bottom end of the movable mounting base 9, a fixed mounting block 11 is fixedly connected to the top end of the movable mounting base 9, a second electric telescopic rod 12 is fixedly connected to one side of the fixed mounting block 11, a fixed support sleeve block 13 is fixedly sleeved on the outside of the other end of the second electric telescopic rod 12, a first connecting frame 14 is fixedly connected to the output end of the second electric telescopic rod 12, a servo motor 15 is provided inside the first connecting frame 14, a fixing groove 16 is provided on the side of the first connecting frame 14 away from the second electric telescopic rod 12, a rotating rod 17 is fixedly connected to the output end of the servo motor 15, a rotating sleeve rod 18 is movably sleeved on the outer surface of the rotating rod 17, the other end of the rotating sleeve rod 18 is fixedly connected to the second connecting frame 19, and a protective pad 20 is provided on one side of the second connecting frame 19.

[0028] The second electric telescopic rod 12 is convenient for pushing the first connecting frame 14, the servo motor 15, the rotating rod 17, the rotating sleeve rod 18, the second connecting frame 19 and the protective pad 20, so that the rack can be clamped and fixed between the protective pads 20, so that the rack can be stably processed, and when the servo motor 15 rotates the rotating rod 17, the rotating sleeve rod 18, the second connecting frame 19 and the protective pad 20 can be driven to rotate, thereby driving the rack to rotate, so as to turn the rack over.

[0029] In another embodiment, if Figure 3 As shown, the outer surface of the rotating rod 17 and the inner surface of the fixing groove 16 are slidably fitted to each other.

[0030] When the rotating rod 17 is rotating, the rotating rod 17 can stably rotate inside the fixing groove 16, which is easy to operate.

[0031] In another embodiment, if Figure 3 As shown, a fixed connecting rod 21 is symmetrically provided on one side of the first connecting frame 14 close to the rotating rod 17, and a connecting limit plate 22 is fixedly connected to the other end of the fixed connecting rod 21. A movable limit sleeve block 23 is movably sleeved on the outer side of the surface of the fixed connecting rod 21, and a fixed installation groove 24 is provided on the inner side of the movable limit sleeve block 23.

[0032] When the servo motor 15 and the rotating rod 17 need to be disassembled and maintained later, the rotating sleeve rod 18 drives the fixed limiting ring 25 to move, so that the fixed limiting ring 25 can drive the movable limiting sleeve block 23 to move outside the surface of the fixed connecting rod 21, so that the rotating rod 17 and the rotating sleeve rod 18 are separated from each other, so that the servo motor 15 can be quickly pulled out from the inner side of the first connecting frame 14, and the rotating rod 17 can be quickly pulled out from the inner side of the fixed groove 16, so that the servo motor 15 and the rotating rod 17 can be quickly disassembled and maintained.

[0033] In another embodiment, if Figure 3 As shown, the outer surface of the fixed limiting ring 25 and the inner surface of the fixed installation groove 24 are slidably fitted with each other.

When the rack needs to be turned over, the first electric telescopic rod 3 can be retracted to lower the height of the lifting plate 4, so that the lifting plate 4 and the rack are separated from each other, and when the servo motor 15 rotates the rotating rod 17, it can drive the rotating sleeve rod 18, the second connecting frame 19 and the protective pad 20 to rotate, thereby driving the rack to rotate, so as to turn the rack over. When the servo motor 15 and the rotating rod 17 need to be disassembled and maintained later, the rotating sleeve rod 18 drives the fixed limiting ring 25 to move, so that The fixed limiting collar 25 can drive the movable limiting sleeve 23 to move on the outer side of the surface of the fixed connecting rod 21, so that the rotating rod 17 and the rotating sleeve rod 18 are disengaged from each other, so that the servo motor 15 can be quickly pulled out from the inner side of the first connecting frame 14, and the rotating rod 17 can be quickly pulled out from the inner side of the fixed groove 16, so that the servo motor 15 and the rotating rod 17 can be quickly disassembled and maintained. When it is necessary to disassemble, maintain, repair or replace the clamping and flipping mechanism 6 as a whole, the connecting lifting rod 30 is pulled up to drive the movable plug rod 27 and the force-bearing collar 28 to move, compressing the force-bearing spring 29, and the bottom end of the movable plug rod 27 can be pulled out from the inner side of the top of the operating table 1, and then the movable mounting base 9 is moved horizontally, so that the movable mounting base 9 is disengaged from the fixed limiting bottom block 5, so that the clamping and flipping mechanism 6 as a whole can be quickly disassembled, maintained, repaired or replaced. The overall structure is simple and the operation is convenient and fast.
