[0002] In existing mechanical processing, one processing method is to process circular plate workpieces on a horizontal boring and milling machine. Since the circular plate workpiece is vertically lifted and clamped, the traditional clamping method has no support for the bottom of the circular plate workpiece and no accurate positioning of the circular plate workpiece, which is time-consuming and labor-intensive during clamping.

[0003] Since the circular plate workpiece is not accurately positioned, the clamping position of the circular plate workpiece is inconsistent, which makes the operation complicated for workers and requires adjustments every time. In addition, the weight of the workpiece itself is too heavy, and there will be great safety hazards every time the operator makes manual adjustments. In addition, since the horizontal boring and milling machine needs to be re-zeroed before each processing, the auxiliary time is too long. Summary of the invention

[0006] Furthermore, the bearing is an oil-free bearing arranged in the shaft hole of the shaft seat.

[0016] The technical solution of the present invention is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0017] The circular plate processing rapid positioning device of the present invention comprises a positioning support mechanism 2 arranged on a tool support 1, wherein the tool support 1 comprises a base and a vertical clamping panel 1-1 (square plate) vertically welded to the front end of the base, and the left and right ends of the vertical clamping panel 1-1 are welded to the base by left and right ribs to enhance stability, and the left and right positioning support mechanisms 2 are symmetrically arranged at the lower part of the plate body on both sides of the vertical center plane of the vertical clamping panel 1-1, such as Figure 1 , Figure 2 shown.

[0018] like Figure 3 , Figure 4 As shown, the structure of the positioning support mechanism 2 is described as follows by taking the left positioning support mechanism 2 as an example:

[0019] The positioning support mechanism 2 includes a rectangular support block 3 (with four positioning support surfaces: upper, lower, left and right), and the rectangular support block 3 is installed on the corresponding position of the vertical clamping panel 1-1 through a rotating pair. The rotating pair includes an axle seat 8 welded on the vertical clamping panel 1-1 and a rotating shaft 7 welded on the rear end surface of the rectangular support block 3. The rotating shaft 7 is installed in an oil-free bearing 9 in the shaft hole of the axle seat 8 and locked in position by a cotter pin 10; the axis of the rotating shaft 7 deviates from the center point of the rectangular support block 3 to the lower left, and the rectangular support block 3 is rotated through the rotating shaft The rotation of 7 can make the mid-vertical planes of the upper, lower, left and right four positioning support surfaces respectively located at the support positions obliquely to the upper right (at an angle of 45° to the horizontal plane). Corresponding to the upper, lower, left and right four support positions, four pin holes 4 are evenly distributed on the circumference of the rectangular support block 3 with the axis of the rotating shaft 7 as the center, and a limiting hole 8-1 is opened on the shaft seat 8. The limiting hole 8-1 is located on the rotation path of the four pin holes 4 on the rectangular support block 3. The limiting hole 8-1 and the pin holes 4 can limit the positions of the positioning support surfaces of the rectangular support block 3 through the inserted axle pins 5.

[0020] The mid-vertical planes between the positioning support surfaces corresponding to the left and right rectangular support blocks 3 intersect vertically upward, and the intersection line (horizontal line in the front and rear directions) is located on the vertical center plane of the vertical clamping panel 1-1. The position of the intersection line is the center position of the circular plate workpiece 6 positioned and supported by the left and right rectangular support blocks 3. The four pairs of positioning support surfaces of the left and right rectangular support blocks 3 can position and support four circular plate workpieces 6 of different sizes, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 shown.

[0021] When the present invention is in use, the left and right rectangular support blocks 3 can be rotated according to the size of the circular plate workpiece 6 to select the corresponding positioning support surface, and after the positioning support gears of the left and right rectangular support blocks 3 are selected, the positions are fixed with the pin shaft 5, and the circular plate workpiece 6 is vertically hoisted into place on the left and right rectangular support blocks 3 with a special lifting device. The left and right rectangular support blocks 3 not only play a supporting role but also accurately position the circular plate workpiece 6, and the centers of circular plate workpieces 6 of different sizes are positioned at the same position.

[0022] When the circular plate workpiece 6 is processed on a horizontal boring and milling machine, the positioning device of the present invention is used to quickly position and support the circular plate workpiece 6 to achieve accurate positioning.
