The back surface of the arc-shaped seat is provided with three positioning cavities 113. The clamping jig is overturned by the clamping and overturning driving mechanism.

[0050] In this embodiment, as shown in Figure 5 , Figure 5 , the bottom surface of the middle positioning block is provided with four positioning columns. Only one is shown in the figure. The clamping jig further comprises a positioning block 15. The lower surface of the positioning block is provided with four positioning columns 151.

[0052] In this embodiment, the upper part of the ring-shaped workpiece is provided with a ring of outwardly extending hanging tables. The hanging tables are hung at the upper opening of the central cavity.

[0053] In this embodiment, as shown in Figure 3 andFigure 4 As shown in the figure, the turnover positioning mechanism 25 includes a positioning rod 251 and a positioning drive cylinder 252, the power output end of the positioning drive cylinder is fixed to one end of the positioning rod, and the other end of the positioning rod is inserted into or pulled out of the positioning cavity by the drive of the positioning drive cylinder.

[0054] In this embodiment, the power output end of the clamping turnover drive mechanism is connected to the bottom plate, and the clamping turnover drive mechanism is a structure matched with a servo motor and a speed reducer. This is prior art, and thus will not be described in detail. The clamping turnover drive mechanism can drive the clamping carrier to turn over by a certain angle.

[0055] In this embodiment, the clamping translation drive mechanism is a structure matched with a motor and a screw rod. This is prior art, and thus will not be described in detail.

[0056] In this embodiment, as shown in the figure, Figure 4 As shown in the figure, the upper end of the support frame is provided with a cylindrical hole 221 for placing a cylindrical pin, and the discharge port of the cylindrical pin feeder is connected to the cylindrical hole through a hose. The hose is not shown in the figure, and other mechanisms can also be used to place the cylindrical pin in the cylindrical hole, and the upper end of the cylindrical pin can be extended.

[0057] In this embodiment, as shown in the figures, Figure 1 , Figure 2 and Figure 11 As shown in the figures, the inclined pin clamping and turnover device 7 includes a gas claw 71, a first turnover drive unit 72, a connecting arm 73, and a second turnover drive unit 74. The gas claw is fixed to the end of the first turnover drive unit, one end of the connecting arm is fixed to the first turnover drive unit, and the other end of the connecting arm is fixed to the power output end of the second turnover drive unit. In this embodiment, the first turnover drive unit is a rotary cylinder, and the second turnover drive unit is a servo motor, but is not limited thereto, and can be any device capable of driving the gas claw to turn over or rotate.

[0058] Figure 2 and Figure 11 Positions A and B in the figures simulate two states of the gas claw. Actually, there is only one gas claw. Position A refers to the state when the inclined pin is taken from the inclined pin feeder 6, and position B refers to the state when the gas claw is right below the second pressing device. At this time, the second pressing device takes away the inclined pin and then presses the inclined pin into the inclined hole of the annular workpiece.

[0059] In this embodiment, since the upper end and the lower end of the inclined pin are different in structure, the detector detects which end of the inclined pin is upward. If the required end is not upward, the first turnover drive unit drives the gas claw to turn over by 180°, and then the second turnover drive unit drives the connecting arm to rotate by 180°, so that the connecting arm is right below the second pressing device (i.e. Figure 2 and Figure 11Position B) in the middle of the screen.

[0060] In this embodiment, the detector is an infrared light detector, a laser detector or an industrial camera.

[0061] As shown in the drawings, the machine table is also provided with a code scanner 100 and a code scanning driving cylinder 200 for scanning the code. Figure 1 The code scanner is driven to translate along the Y direction by the code scanning driving cylinder, and the code scanner is used to scan and record the annular workpiece.

[0062] In this embodiment, the first and second pressing devices are used to suck the cylindrical pin or inclined pin by vacuum or magnetic attraction, and then press them into the straight hole and inclined hole of the annular workpiece respectively.

[0063] The working principle and working process of the utility model:

[0064] Press the cylindrical pin into the straight hole of the annular workpiece: the clamping and translating driving mechanism drives the clamping jig to the right side of the machine table (the right side of the machine table is the side of the machine table farthest from the operator), and the annular workpiece is placed in the center cavity of the profiling block manually or by other automatic material taking and placing mechanisms. Figure 2 The upper part of the clamping jaw is located inside the annular workpiece, and then the positioning block is taken to make the positioning column inserted into the positioning hole and the straight hole, indicating that the annular workpiece is placed in position. If it cannot be inserted at the same time, the annular workpiece is rotated until the positioning column is inserted into the positioning hole and the straight hole. Then the two clamping jaw driving cylinders act to drive the connecting rod to descend and drive the top block to descend. Through the cooperation of the inclined outer peripheral surface of the top block and the inclined inner wall surface of the clamping jaw, the clamping jaw arm is expanded and supported, and finally the annular workpiece is supported and fixed. At this time, the positioning driving cylinder drives the positioning rod to be inserted into the positioning cavity in the middle of the arc-shaped seat. The cylindrical pin is fed by the cylindrical pin feeder and enters the cylindrical hole of the support frame through the hose. Because the two ends of the cylindrical pin have the same structure and do not need to be distinguished, the cylindrical pin stands in the cylindrical hole at this time. The clamping and translating driving mechanism drives the support frame to move so that the cylindrical hole is located directly below the first pressing device, and the cylindrical pin is taken out. Then the clamping and translating driving mechanism drives the support frame to move so that the straight hole of the annular workpiece is located directly below the first pressing device. Then the cylindrical pin is pressed into the straight hole, and the other cylindrical pin is pressed into the other straight hole of the annular workpiece.

[0065] The inclined pin is pressed into the inclined hole of the annular workpiece: then the positioning driving cylinder drives the positioning rod to pull out, and then the clamping overturning driving mechanism drives the clamping fixture to overturn by a certain angle until the positioning driving cylinder drives the positioning rod to insert into the positioning cavity on one side, and the clamping translation driving mechanism drives the clamping fixture to be directly below the second pressing device; at the same time, the inclined pin is automatically fed through the inclined pin feeder, and then the gas gripper clamps the inclined pin, since the upper end and the lower end of the inclined pin are different in structure, the upper end and the lower end are distinguished, so the detector detects which end of the inclined pin is upward, if the required end is upward, the first overturning driving unit does not need to act; if the required end is not upward, the first overturning driving unit drives the gas gripper to overturn 180° upward and downward, then the second overturning driving unit drives the connecting arm to rotate 180° left and right, so that it is located directly below the second pressing device, then the second pressing device takes the inclined pin, and then the gas gripper is loosened, and then the second pressing device presses the inclined pin into one of the inclined holes; similarly, the other inclined pin is pressed into the other inclined hole of the annular workpiece, and then the clamping translation driving mechanism drives the clamping fixture to the right side of the machine table Figure 2 ) unloading;

[0066] In the above process, the code scanning driving cylinder can also drive the code scanner to translate along the Y direction, and the code scanner can scan and record the annular workpiece.

[0067] The above is only an embodiment of the present application, and is not limited to the above, and does not limit the patent range of the present application, and any equivalent structure or direct or indirect application in other related technical fields is also included in the patent protection range of the present application.
