DETAILED DESCRIPTION

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of 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. Example
[0026] A locator for processing and polishing eyeglass frames comprises two brackets 1 arranged opposite to each other, a threaded rod 2 is rotatably mounted on one end of one side of the bracket 1, an adjusting plate 3 located on the outside of the bracket 1 is threadedly mounted on the surface of the threaded rod 2, evenly distributed clamping arms 4 are penetrated between the bracket 1 and the adjusting plate 3, and positioning holes 5 distributed at equal intervals are opened on the top of the clamping arms 4, one end of the clamping arms 4 is fixedly connected to a baffle 8 located on the outside of the adjusting plate 3, a spring 9 is sleeved on the surface of the clamping arms 4, and the two ends of the spring 9 are respectively fixedly connected to the baffle 8 and the adjusting plate 3, one side of the bracket 1 is provided with through holes 6 evenly distributed and matched with the clamping arms 4, one side of the adjusting plate 3 is provided with through holes 7 evenly distributed and matched with the clamping arms 4, a positioning component matched with the positioning holes 5 is penetrated on the top of the bracket 1, and reserved mounting holes 19 are opened on both sides of the bottom of the bracket 1.
[0027] The specific usage process is as follows: first, when grinding a frame that matches the size of the frame clamping block 15, the user can directly put the frame onto the frame clamping block 15. In this way, the frame clamping block 15 is stuck in the frame, and the frame can be positioned to ensure that the frame will not move at will during the grinding process. Then the user can grind the frame. After grinding one side, the frame can be removed and turned over for grinding again. In this way, the burrs on the surface of the frame can be polished smooth to facilitate later spraying processing. After grinding, the frame can be directly removed. If it is a large-sized frame, when grinding, the user first pulls up the positioning assembly composed of the positioning pin 10, the connecting rod 11, the spring 12, and the pull rod 13 to release the restriction on the clamping arm 4, and then rotates the threaded rod 2. The threaded rod 2 is threadedly connected to the adjustment plate 3, and under the restriction of multiple clamping arms 4, the threaded rod 2 will drive the adjustment plate 3 to move toward the outside of the bracket 1, because the spring 1 9 connected to the baffle 8 is also connected to the adjustment plate 3, and the baffle 8 is fixed on the clamping arm 4. Therefore, when the adjustment plate 3 moves, it will also drive all the clamping arms 4 to move, so that the distance between the two brackets 1 is adjusted and expanded, and the two side walls of the inner cavity of the through hole 2 7 are not smooth, but are wavy like the two sides of the clamping arm 4. Therefore, it can also limit the clamping arm 4 when the adjustment plate 3 moves, so that the clamping arm 4 moves with the adjustment plate 3, and the inner wall of the through hole 1 6 is smooth, which will not affect the movement of the clamping arm 4. It should be noted that the setting of the shape of the inner cavity of the through hole 2 7 , it will not completely restrict the clamping arm 4 from working inactively. When the external force is greater than the friction between the clamping arm 4 and the inner wall of the through hole 7, the clamping arm 4 can slide in the inner cavity of the through hole 7. This is the prior art. After adjustment, the user places the frame that needs to be processed on the frame block 15. Since the size of the frame block 15 is smaller than the frame, it is difficult to position the frame. After that, the user needs to reversely rotate the threaded rod 2 again to push the adjustment plate 3 back in the direction of the bracket 1, so that the clamping arm 4 will move back with it, and the end of the clamping arm 4 facing the frame will contact the frame, and then continue to rotate the threaded rod 2. When the clamping arm 4 contacts the frame, it will also be blocked by the frame, and then the clamping arm 4 will be pushed outward. At this time, the reverse thrust generated by the frame is greater than the friction between the clamping arm 4 and the through hole 7. Due to the friction force of the inner wall of the second hole 7, the clamping arm 4 will move outward in the corresponding through hole 27, and the clamping arm 4 will also drive the baffle 8 to move, and the baffle 8 will stretch the spring 19. Under the joint action of the spring 19 and the inner wall of the second hole 7 on the clamping arm 4, the frame is clamped and positioned. Moreover, since each clamping arm 4 can move freely, all the clamping arms 4 can fit on the surface of the frame to firmly position the frame, ensuring that the frame will not move arbitrarily during the grinding work. Moreover, even large-sized frames can be positioned in the above manner, which provides convenience for users, and small-sized frames can also be directly placed on the frame block 15, and then clamped and positioned by the clamping arm 4. In this way, the positioner can meet the positioning requirements of large-sized frames.It can also realize the positioning of small-sized frames, expand the use range of the positioner, improve the flexibility of the positioner, and the positioner has more contact points with the frame, and the stability after positioning is also higher.
[0028] Therefore, a design is adopted that can achieve tight fitting and clamping according to the surface shape of the product. When clamping and fixing the product, each clamping arm will move independently to adapt to the surface shape of the product and fit on the surface of the product to clamp the product mutually, thereby completing the positioning of frames of different types and sizes, providing convenience for the user's polishing work.
[0029] The positioning assembly includes a plurality of positioning pins 10 plugged into the bracket 1, the top of the bracket 1 is provided with a socket connected to the through hole 6, the positioning pins 10 are adapted to the positioning hole 5, the tops of the plurality of positioning pins 10 are fixedly connected with a connecting rod 11, and the tops of the connecting rod 11 are fixedly connected with a pull rod 13.
[0030] Specifically, with the setting of the positioning assembly, the pull rod 13 can pull the connecting rod 11 by lifting the pull rod 13, and the connecting rod 11 will simultaneously drive all the positioning pins 10 to move upward, and then all the positioning pins 10 will also move out from the positioning holes 5, which can limit the contact of all the clamping arms 4. In this way, all the clamping arms 4 can move flexibly, and can clamp and fix the frame according to the shape of the frame, providing convenience for the user's polishing work. Similarly, all the clamping arms 4 can also be positioned to ensure the stability of the frame after being clamped.
[0031] Two springs 12 are fixedly connected to both sides of the bottom of the connecting rod 11 . The two springs 12 are respectively sleeved on the corresponding two positioning pins 10 . One end of the spring 12 away from the connecting rod 11 is fixedly connected to the bracket 1 .
[0032] Specifically, the setting of spring 2 12 will stretch spring 2 12 upward when the connecting rod 11 is pulled for use. When the user releases the connecting rod 11 after use, the connecting rod 11 will be pulled back to its original position under the action of spring 2 12, so that the user can use it next time, providing convenience for the user's work.
[0033] A support plate 14 is disposed between the two brackets 1 , and connecting bolts 16 are penetrated at both ends of the support plate 14 . The support plate 14 is fixedly mounted on the two brackets 1 by the connecting bolts 16 .
[0034] Specifically, the support plate 14 is provided with the frame block 15 which is provided on the support plate 14 to support and ensure the stability of the frame block 15, to provide convenience for the user and to improve the grinding accuracy of the frame. The support plate 14 is also used to support the two brackets 1 to ensure the stability of the two brackets 1 after installation.
[0035] The two ends of both sides of the support plate 14 are provided with bolt holes 17 adapted to the connecting bolts 16 , and the two ends of one side of the bracket 1 are provided with bolt holes 18 adapted to the connecting bolts 16 .
[0036] Specifically, the connection bolt 16, bolt hole 17 and bolt hole 2 18 are arranged, and the bolt hole 17 and bolt hole 2 18 are both used to install the connection bolt 16. During installation, the connection bolt 16 is inserted from the bolt hole 17 on the support plate 14 and the connection bolt 16 is controlled to be inserted into the bolt hole 2 18 on the bracket 1. Finally, the connection bolt 16 is tightened to fasten the support plate 14 between the two brackets 1. At the same time, it can also be quickly disassembled, which provides convenience for users to use and carry.
[0037] The top of the support plate 14 is integrally formed with two frame blocks 15 , and the surfaces of the two frame blocks 15 are sleeved with frames.
[0038] Specifically, the two frame clamps 15 form a mold for sleeved frames, so as to place the frames, realize the positioning of the frames, ensure the stability of the frames during grinding, and provide convenience for users' work.
