DETAILED DESCRIPTION

[0018] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0019] See also Figure 1-5 The utility model provides a technical solution: a spring chamfering mechanism, comprising a bracket 1, a support plate 2 is fixedly connected to one side surface of the bracket 1, a first motor 3 is fixedly connected to one side surface of the support plate 2, a connecting shaft 4 is fixedly connected to one end of the first motor 3, a triangular crawler 5 is fixedly connected to one end of the connecting shaft 4, an adjusting mechanism 6 is arranged on one side surface of the bracket 1, and a cleaning mechanism 7 is arranged on one side surface of the bracket 1;

[0020] The adjusting mechanism 6 includes a first slide groove 601, a second slide groove 602, a third slide groove 603, a sliding base 604, a second motor 605, a fixing screw 606, a fixing nut 607, a grinding blade 608, a limiting groove 609 and a conveying rack 610. The first slide groove 601 is provided on one side surface of the bracket 1, the second slide groove 602 is provided on one side surface of the bracket 1, the third slide groove 603 is provided on one side surface of the bracket 1, a sliding base 604 is arranged inside the first slide groove 601, one side surface of the sliding base 604 is fixedly connected with the second motor 605, a fixing screw 606 is provided on one side surface of the sliding base 604, and the fixing nut 607 is threadedly connected to the outer surface of the fixing screw 606, a limiting groove 609 is provided on one side surface of the sliding base 604, and the conveying rack 610 is arranged inside the limiting groove 609. 601, the second slide groove 602, the third slide groove 603, the sliding base 604, the second motor 605, the fixing screw 606, the fixing nut 607, the grinding blade 608, the limiting groove 609 and the conveying frame 610 are set. When adjustment is needed, the fixing nut 607 is first unscrewed from the fixing screw 606, and then the sliding base 604 is pulled to slide, so that it slides in the first slide groove 601 and the second slide groove 602, thereby driving the second motor 605 to slide. When adjusted to the appropriate position, the fixing screw 606 and the fixing nut 607 are threadedly connected to fix them in the third slide groove 603 and tighten them. Then, the conveying frame 610 with a suitable spring size is replaced and installed through the limiting groove 609 so that it is engaged between the sliding base 604 and the support plate 2, and then the chamfering can be polished.

[0021] Furthermore, eight groups of first slide grooves 601 are provided on the bracket 1, and two groups of sliding bases 604 are provided on the bracket 1. By providing the first slide grooves 601 on the bracket 1, the sliding base 604 can slide better, thereby adapting to more types of spring sizes. By providing the sliding base 604 on the bracket 1, the second motors 605 on both sides can be better driven for grinding, thereby preventing the chamfer of the spring from being ground too large or too small.

[0022] Furthermore, the second motor 605 is provided with four groups on the sliding base 604, and the outer surface of the fixing screw 606 is in contact with the inner surface of the third slide groove 603. By setting the second motor 605 on the sliding base 604, the spring can be better polished and chamfered. The four-group setting can enable it to perform multiple fine polishing, so that the polished surface of the spring is smoother. By setting the fixing screw 606 and the third slide groove 603, the sliding base 604 can be better fixed, so that there will be no offset problem during polishing.

[0023] Furthermore, the cleaning mechanism 7 includes a blower 701, an air pipe 702, an air nozzle 703, a chip guard plate 704 and a chip receiving bucket 705. The blower 701 is fixedly connected to the surface of one side of the sliding base 604, the air pipe 702 is fixedly connected to the outer surface of the blower 701, the air pipe 702 is fixedly connected to the surface of one end of the air pipe 702, the air nozzle 703 is fixedly connected to the outer surface of the sliding base 604, and the chip guard plate 704 is embedded on the outer surface of the sliding base 604. The outer surface of the bracket 1 is provided with a chip receiving bucket 705. The chip plate 704 and the chip bucket 705 are set up. When it is necessary to clean the iron chips, first install the chip plate 704 of appropriate size on the sliding base 604. When grinding, turn on the blower 701 and the gas will be transported through the gas pipe 702, and then sprayed through the nozzle 703, so that the iron chips after grinding are blown away, so that the stickiness of the iron chips can be reduced each time the spring is grinded, so that it can be polished more smoothly. After that, the blown iron chips will fall into the chip bucket 705 for collection, which can reduce the scattering of a certain amount of iron chips.

[0024] Furthermore, the air pipe 702 has four branches, and four groups of nozzles 703 are arranged on the sliding base 604. Through the arrangement of the air pipe 702, the nozzles 703 can be better driven to spray, thereby blowing away the iron filings. Through the arrangement of the nozzles 703 on the sliding base 604, the spring can be better purged each time it is polished, thereby better performing the next polishing or discharging.

[0025] Working principle: First, when the spring needs to be ground and chamfered, the first motor 3 is started first, and then the first motor 3 rotates, thereby driving the connecting shaft 4 to rotate, and then driving the triangular track 5 to rotate. At this time, the spring to be ground is placed in the conveying rack 702, and the triangular track 5 drives the spring to drive inward. At this time, the second motor 605 is started so that the second motor 605 drives the grinding blade 608 to grind. At this time, the blower 701 is also turned on, and then the gas is delivered through the gas pipe 702, and then the gas is sprayed through the nozzle 703, so that the iron filings after grinding are blown away, so that the stickiness of the iron filings can be reduced each time the spring is ground, so that it can be ground more smoothly, and then the iron filings will fall into the chip receiving bucket 705 for collection. At this time, each time it is ground, it will be purged until the spring is discharged.

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