DETAILED DESCRIPTION

[0022] 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.

[0023] See also Figure 1-4 In this embodiment, a metal casting positioning and feeding device includes a frame 1, on which a feeding mechanism 2 and a positioning mechanism 3 are provided. The workpiece is sent to the positioning mechanism 3 through the feeding mechanism 2 and is firmly clamped by the positioning mechanism 3, so that the processing equipment can process the workpiece.

[0024] The feeding mechanism 2 can transport several workpieces in an orderly manner, improving the continuity of workpiece processing. Figure 2-3 As shown, the feeding mechanism 2 includes a feeding rack 201 fixed to the right side of the frame 1, and four fixed support plates 202 distributed at equal intervals are fixed on the feeding rack 201. Several workpieces can be placed on the four fixed support plates 202 at intervals, and a moving cylinder 203 is fixed on the feeding rack 201. The output shaft of the moving cylinder 203 is fixed with a moving plate 204, and a pair of lifting cylinders 205 are fixed on the top surface of the moving plate 204. The output shaft of the lifting cylinder 205 is fixed with a lifting plate 206, and three movable support plates 207 distributed at intervals from the fixed support plate 202 are fixed on the top surface of the lifting plate 206. Several arc-shaped support grooves with the same spacing are provided on the movable support plate 207 and the fixed support plate 202. Several workpieces are supported by the arc-shaped support grooves on the fixed support plate 202, and then the workpieces are driven to move in sequence by the movable support plate 207 which can move horizontally and vertically, so that the workpieces can be loaded in an orderly manner and the loading is more regular.

[0025] A horizontal guide rail 208 is fixed on the feeding rack 201, and a horizontal guide slider 209 slidably connected to the horizontal guide rail 208 is fixed on the moving plate 204. Under the guiding action of the horizontal guide rail 208 and the horizontal guide slider 209, the moving plate 204 moves more smoothly. Rectangular guide sleeves 210 are fixed to the four corners of the moving plate 204, and a guide column 211 extending into the rectangular guide sleeve 210 is fixed on the lifting plate 206. Under the guiding action of the rectangular guide sleeve 210 and the guide column 211, the lifting plate 206 moves more smoothly.

[0026] The side of the feeding rack 201 is provided with a limiting groove corresponding to the movable support plate 207, so that the end of the movable support plate 207 can extend to the positioning mechanism 3. A sloped material guide plate 212 is fixed on the frame 1. The sloped material guide plate 212 is provided with a positioning groove corresponding to the limiting groove. The end of the movable support plate 207 extends into the positioning groove. The movable support plate 207 moves downward in the positioning groove, and the workpiece on the movable support plate 207 falls onto the sloped material guide plate 212 and rolls to the positioning mechanism 3 under the guidance of the sloped material guide plate 212. A pair of symmetrically arranged guardrails 213 are also fixed on the feeding rack 201 to limit the front and rear ends of the workpiece.

[0027] The positioning mechanism 3 can firmly hold the workpiece, improve the accuracy of workpiece processing, and thus improve product quality. Figure 4 As shown, the positioning mechanism 3 includes a pair of support rollers 301 arranged on the frame 1, and the sloped guide plate 212 extends to one side of the support roller 301. The workpiece can slide from the sloped guide plate 212 to between the two support rollers 301 and be supported by the two support rollers 301. A pair of suction nozzles 302 located between the two support rollers 301 are also installed on the frame 1. The workpiece slides between the two support rollers 301 and is sucked by the suction nozzles 302, so that the workpiece can be preliminarily positioned.

[0028] A pair of relatively arranged telescopic cylinders 303 are also fixed on the frame 1, and a positioning column 304 is fixed to the output end of the telescopic cylinder 303. When the two telescopic cylinders 303 are pushed out, the positioning column 304 can fine-tune the position of the workpiece to make the position of the workpiece more centered and facilitate subsequent processing.

[0029] A positioning cylinder 305 is fixed on the frame 1, and a clamping cylinder 306 is fixed to the output shaft of the positioning cylinder 305. The two jaws of the clamping cylinder 306 are parallel to the supporting roller 301. In the initial state, the positioning cylinder 305 is in an ejection state to prevent the clamping cylinder 306 from affecting the workpiece to slide onto the two supporting rollers 301. When the clamping operation is required, the positioning cylinder 305 retracts, and finally the workpiece is clamped and stabilized by the clamping cylinder 306, which is convenient for processing the workpiece.

[0030] By adopting the above-mentioned metal casting positioning and loading device, the workpieces can be loaded in an orderly manner. The specific loading method is as follows:

[0031] In the initial state, the movable support plate 207 is located at the rightmost end and is lower than the height of the fixed support plate 202. Several workpieces can be supported by the arc-shaped support groove on the fixed support plate 202, so that the workpieces can be arranged in an orderly manner. When loading, the lifting cylinder 205 is ejected, the movable support plate 207 moves up, and the moving cylinder 203 retracts. The movable support plate 207 can drive the workpiece to move left until the end of the movable support plate 207 extends into the positioning groove of the slope guide plate 212. The lifting cylinder 205 retracts, and the leftmost workpiece can fall onto the slope guide plate 212 and slide onto a pair of support rollers 301. The suction nozzle 302 can suck the workpiece, and the positioning column 304 can also fine-tune the position of the workpiece to make the position of the workpiece more centered. The positioning cylinder 305 retracts, and the clamping cylinder 306 moves down to clamp the left and right sides of the workpiece firmly. After the workpiece is positioned, it can be processed.

[0032] When the movable support plate 207 returns to the initial position, a new workpiece can be loaded and processed again. The above operation is repeated to continuously load and process the workpiece.

[0033] The control method of the present invention is controlled by a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0034] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0035] 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.
