[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] (1) By setting up components such as a press-fitting drive electric cylinder and a spindle switching assembly, the spindle switching electric cylinder is started. Under the action of the spindle switching guide column, the spindle switching seat is pushed by the output end of the spindle switching electric cylinder to adjust the left and right positions, thereby switching different spindle switching components, so that different contact plates are pressed down by the press-fitting plate, thereby pressing the preset steel balls into the workpiece.

[0021] (2) By setting up components such as a steel ball silo and a steel ball outlet, open the top cover and put the steel balls to be used into the steel ball silo. The observation window is used to observe the internal steel ball storage. The steel ball pressure-feeding electric cylinder is started to drive the steel ball top plate to rise so that it matches the inside of the steel ball slide-out part to allow the steel balls to pass through the steel ball outlet and be sent out. The steel balls are sent into the steel ball inlet through the connected pipe for pressure feeding. The two groups of steel ball silos can hold steel balls of different sizes or steel balls of the same size. Steel balls of a certain size in one group of steel ball silos can enter one or another group of steel ball inlets through the pipe, and steel balls of a certain size in another group of steel ball silos can enter one or another group of steel ball inlets through the pipe. Different steel ball conveying methods can be changed according to the pressing requirements.

[0022] (3) By setting up components such as the limit drive unit moving forward and backward electric cylinder, the workpiece switching left electric cylinder, and the workpiece switching right electric cylinder, after determining the workpiece to be pressed, start the limit drive unit moving left and right electric cylinder to adjust the horizontal position of the limit drive unit moving forward and backward electric cylinder, so that the workpiece push block can select and connect with the appropriate first push plate or second push plate. When removing the completed workpiece and adding a new workpiece, start the workpiece switching left electric cylinder or the workpiece switching right electric cylinder to push the first fixed part or the second fixed part to the position to be pressed, start the limit drive unit moving forward and backward electric cylinder, and use the limit drive unit moving forward and backward electric cylinder to push the workpiece push block to send the workpiece (brake master cylinder) to the predetermined position and complete the limit. After the steel ball is pressed, the workpiece is pushed. The feeding block withdraws, and under the influence of the hook spring, the first movable part or the second movable part falls back, releasing the limit of the brake master cylinder, and switching to the next workpiece for pressing. The number of the first fixed part or the second fixed part corresponds to the number of steel ball pressing modules, and both of them can be switched to realize the steel ball pressing of multiple models of brake master cylinders. The side calibration head is used for calibration limit of the workpiece. Two notches are provided on one side of the workpiece, and a reserved groove matching the aforementioned notches is provided on the left side of the side calibration head to prevent dust from entering the inside of the workpiece during pressing. At the same time, after power is turned on, the side calibration part is used to move the electric cylinder up and down to adjust the up and down position of the side calibration head, and the side calibration part is used to move the electric cylinder left and right to adjust the left and right position of the side calibration head, so that the side calibration head is consistent with the side of the workpiece to achieve calibration limit.

The steel ball pressing and feeding electric cylinder 807 is started to drive the steel ball top plate 809 to rise, so that it coincides with the inside of the steel ball slide-out part 806 to allow the steel balls to pass through the steel ball outlet 805 and be sent out. The steel balls are sent into the steel ball inlet 911d through the connected pipe for pressing and feeding. The spindle switching electric cylinder 909 is started. Under the action of the spindle switching guide column 910, the spindle switching seat 912 is pushed by the output end of the spindle switching electric cylinder 909 to adjust the left and right positions, thereby switching different spindle switching components 911. After determining the workpiece that needs to be pressed, the limit drive unit left and right moving electric cylinder 1510 is started to adjust the limit drive unit forward and backward moving electric cylinder 1514 , so that the workpiece pushing block 1519 can select the appropriate first pushing plate 1517a or second pushing plate 1517b for connection. When the completed workpiece is removed and a new workpiece is added, the workpiece switching left electric cylinder 1508 or the workpiece switching right electric cylinder 1511 is started to push the first fixed part 1512a or the second fixed part 1513a to the position where pressing is required, and the limit driving part is started to move the electric cylinder 1514 forward and backward. The workpiece pushing block 1519 is pushed by the limit driving part to move the electric cylinder 1514 forward and backward, and the brake master cylinder is sent to the predetermined position and the limit is completed. After the steel ball is pressed, the workpiece pushing block 1519 is withdrawn, and under the influence of the hook spring, the first movable part 1512b or the second movable part 1513b falls back, the limit of the brake master cylinder is released, and the next workpiece is switched for pressing.
