[0039] The present application provides an embodiment: a multi-workpiece rapid clamping and positioning tool, comprising a shell 1, the bottom end of the side wall of the shell 1 is fixedly connected with a mounting foot 2, the surface of the mounting foot 2 is provided with an annular groove, and the whole can be fixed on the workpiece machining table through the cooperation of the annular groove and the bolt, the top end of the outer wall of the shell 1 is fixedly connected with two groups of partition plates 3, the different workpieces can be separated through the partition plates 3, so that the workpieces are not hindered during machining, and the inner side of the shell 1 is provided with a positioning mechanism 4. Figure 3 Figure 4 ​​​The top end of the outer wall of the connecting plate 44 is in contact with the top end of the inner side wall of the shell 1, the outer wall of the connecting plate 44 is matched in size with the inner cavity of the shell 1, so that the connecting plate 44 can only move forward and backward on the inner wall of the shell 1, the plug rod 48 penetrates and is slidingly connected to the inner wall of the fixed block 43, the outer side wall of the connecting plate 44 is provided with three groups of connecting rods 45, the middle connecting rod 45 is fixedly connected to the outer side wall of the connecting plate 44, and the two side connecting rods 45 penetrate and are slidingly connected to the inner wall of the connecting plate 44 through the limiting assembly 410. When the connecting plate 44 moves, the three groups of connecting rods 45 are driven to move synchronously, so that the two groups of hinged rods 46 at the bottom ends of the three groups of connecting rods 45 drive the corresponding positioning plates 47 to move close to each other, so that the workpieces can be clamped and positioned, and the two side connecting rods 45 can be moved separately, so that the length of the connecting rod 45 can be extended and adjusted when fixing three groups of workpieces of different sizes. The outer wall of the end of the three groups of connecting rods 45 is hinged with two groups of hinged rods 46, and the positioning plates 47 are hinged at the ends away from the connecting rods 45.

[0040] With reference to Figure 2 - Figure 4 A guide groove is formed in the surface of the top end of the shell 1, and the bottom end of the outer wall of the positioning plate 47 penetrates and is slidingly connected to the inner wall of the guide groove. By forming the guide groove matching the positioning plate 47 on the surface of the shell 1, the two groups of positioning plates 47 can only move close to or away from each other at the top end of the shell 1, so that workpieces of different sizes can be clamped and positioned. The inner wall of the fixed block 43 is elastically connected with the plug rod 48 through the limiting spring 49, one end of the limiting spring 49 is fixedly connected to the surface of the plug rod 48, and the other end of the limiting spring 49 is fixedly connected to the inner wall of the fixed block 43. The limiting spring 49 functions to automatically reset the position of the plug rod 48 after being pulled outward. A through hole is formed in the surface of the threaded block 42, and the end of the plug rod 48 is inserted into the inner wall of the through hole. The plug rod 48 and the through hole are inserted into each other, so that the fixed block 43 and the connecting plate 44 can be fixed at multiple positions on the surface of the threaded block 42, so that three groups of workpieces can be quickly clamped and fixed. At the same time, the threaded block 42 can be moved in threads by the threaded rod 41, so that the fixed block 43 and the connecting plate 44 can be fine-tuned with the threaded block 42, to prevent the clamping from being too tight or too loose.

[0041] With reference to Figure 3 and Figure 5The limiting assembly 410 comprises a limiting rod 412 which is elastically connected to the inner wall of the front end of the connecting plate 44 by a reset spring 411, one end of the reset spring 411 is fixedly connected to the surface of the limiting rod 412, the other end of the reset spring 411 is fixedly connected to the inner wall of the front end of the connecting plate 44, the reset spring 411 is used to automatically reset the position after the reset spring 411 is pulled outward, the limiting rod 412 penetrates and is slidingly connected to the inner wall of the front end of the connecting plate 44, the two side connecting rods 45 penetrate and are slidingly connected to the inner wall of the connecting plate 44, the side wall of the connecting rod 45 is provided with a slot hole, the distal end of the limiting rod 412 is inserted into the inner wall of the slot hole, and the two are inserted between each other, so that the two side connecting rods 45 can drive the hinged rods 46 and the positioning plates 47 to move and adjust the position of the workpieces of different sizes and fix the position, so that the movement of the connecting plate 44 can clamp and fix three workpieces of different sizes at the same time.

[0042] Working principle: before clamping the workpiece, according to the size and quantity of the workpiece, the positioning mechanism 4 is preliminarily adjusted, if three workpieces of different sizes are to be clamped, the limiting rod 412 can be pulled to make it separate from the slot hole in the side wall of the two side connecting rods 45, and the reset spring 411 is compressed, at this time, the two side connecting rods 45 can be moved alone to adjust the length of the extension to adapt to the position requirement of different workpieces, after adjustment, the limiting rod 412 is inserted into the corresponding slot hole under the action of the reset spring 411 to fix the position of the two side connecting rods 45.

[0043] In the process of positioning the workpiece, the workpiece is placed between the positioning plates 47 at the top end of the shell 1, and then the plug rod 48 can be pulled outward to make it separate from the plug-in of the through hole in the current position of the threaded block 42, and the limiting spring 49 is elastically compressed, at this time, the fixed block 43 can be directly pushed to drive the connecting plate 44 to move, the movement of the connecting plate 44 drives the three groups of connecting rods 45 to move synchronously, the hinged rods 46 at the ends of the connecting rods 45 move accordingly, so that the two groups of positioning plates 47 approach each other in the guide groove at the top end of the shell 1 to quickly clamp and position the workpiece, at this time, the plug rod 48 is loosened and it is inserted into the through hole in the surface of the threaded block 42 under the action of the limiting spring 49, the fixed block 43 drives the connecting plate 44 to be fixed in the position of the surface of the threaded block 42, so as to stably fix the workpiece, at this time, the threaded rod 41 can be operated to rotate, since the threaded block 42 is in contact with the bottom end of the inner side wall of the shell 1, it cannot rotate with the threaded rod 41, but only can move in threads on the threaded rod 41, the movement of the threaded block 42 pushes the fixed block 43 in contact with it to move, the fixed block 43 drives the connecting plate 44 to move back and forth in the inner wall of the shell 1, so that the three groups of connecting rods 45 can approach each other through the two groups of hinged rods 46 to drive the corresponding positioning plates 47, so as to finely adjust the clamping of the positioning plates 47 and the workpiece.

[0044] Finally, it should be noted that: the above only for the preferred embodiments of the present application, and is not intended to limit the present application, although the foregoing embodiments of the present application has been described in detail, for the skilled in the art, it still can be modified, or for part of the technical features of the equivalent replacement, the spirit and principles of the present application, made any modification, equivalent replacement, improvement, etc., should be included within the scope of the present application.
