[0026] Example

[0027] Reference Figure 1-Figure 3 , which is an embodiment of the utility model, provides a high-efficiency grinding and positioning fixture for metal processing, including: a main unit 100, a metal positioning unit 200 and a waste chip collection unit 300.

[0028] The main unit 100 includes a support arm 101 and a metal plate 102 located on one side of the support arm 101. The outer surface of the support arm 101 is plated with an anti-corrosion coating of uniform thickness, and the thickness of the support arm 101 is consistent with that of the bending plate 202. The setting of the anti-corrosion coating improves the overall anti-corrosion ability of the bending plate 202.

[0029] The metal positioning unit 200 includes a reduction motor 201 fixedly mounted on the support arm 101 and a bending plate 202 fixedly connected to the output shaft of the reduction motor 201, a symmetrically positioned fixing ear 203 is fixedly mounted on the back side of the bending plate 202, a rotating rod 204 is rotatably connected between the two fixing ears 203, and a symmetrically positioned moving block 205 is threadedly connected to the rotating rod 204, each moving block 205 is fixedly connected to a clamping sleeve 207 through a connecting block 206, and a strip opening matching the connecting block 206 is opened on the bending plate 202, two clamping sleeves 207 are abutted against the metal plate 102, and a frosted pad is padded on the inner wall of each clamping sleeve 207, and the frosted pad is abutted against the metal plate 102, and the provision of the frosted pad increases the friction between the clamping sleeve 207 and the metal plate 102, thereby improving the positioning effect of the clamping sleeve 207 on the metal plate 102.

[0030] The waste collecting unit 300 comprises a waste collecting box 301 and a cover plate 302 hinged to the waste collecting box 301, the cover plate 302 is made of transparent plastic, and a pull handle is fixedly connected to the lower end of the side wall of the cover plate 302, the cover plate 302 made of transparent plastic is convenient for the staff to observe the amount of metal waste in the waste collecting box 301, so as to collect the metal waste in it in time, and the setting of the pull handle is convenient for opening the cover plate 302, the lower end of the support arm 101 is fixedly connected to one end of the upper side wall of the waste collecting box 301, and a waste collecting tray 303 is fixedly installed at the center of the upper side wall of the waste collecting box 301, a material dropping port connected to the waste collecting box 301 is opened at the center of the waste collecting tray 303, and scrapers 304 with symmetrical positions are slidably installed on both sides of the waste collecting tray 303;

[0031] Each scraper 304 is configured to be bent, and the upper side wall of the scraper 304 is inclined. This configuration is to ensure that the scraper 304 falls on the back side of the scraper 304 when scraping the metal scraps in the scrap collection tray 303 into the scrap collection box 301, which makes it inconvenient for the thick scraper 304 to clean these metal scraps. A symmetrical fixed plate 305 is fixedly installed on one side of the scrap collection tray 303, and a servo motor 306 is fixedly installed on one of the fixed plates 305. The output shaft of the servo motor 306 passes through the fixed plate 305 and is fixedly connected to a rotating column 307. The rotating column 307 is provided with symmetrical reciprocating threaded portions, and each reciprocating threaded portion is threadedly connected to a corresponding threaded block 308. The threaded block 308 is fixedly connected to the scraper 304 by a connecting rod 309, and a strip opening matching the connecting rod 309 is opened on the scrap collection tray 303.

[0032] During use, the metal plate 102 to be polished is installed between the clamping sleeves 207, and the rotating rod 204 is rotated. The moving block 205 threadedly connected thereto drives the clamping sleeve 207 to position the metal plate 102 through the connecting block 206. After the grinding of the cut surface on one side of the metal plate 102 is completed, when the other side needs to be polished, it is only necessary to control the output shaft of the reduction motor 201 to drive the bending plate 202 and the metal plate 102 to rotate 180 degrees, and the other side can be polished. There is no need to repeatedly load and unload the metal plate 102, which saves the time required for loading and unloading the metal plate 102 back and forth;

[0033] The waste chips generated by grinding fall into the waste chip collection tray 303 due to the influence of gravity, and the output shaft of the servo motor 306 drives the rotating column 307 to rotate, and the threaded block 308 threadedly connected to the rotating column 307 drives the scraper 304 to move back and forth, thereby regularly scraping the metal waste chips in the waste chip collection tray 303 into the waste chip collection box 301, and the staff does not need to manually clean the metal waste chips in the waste chip collection tray 303.

[0034] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
