Detailed Implementation Manner:

[0042] The following further describes the present utility model with specific embodiments. Refer to Figure 1 —6:

[0043] The honing and reaming processing equipment for the bushing includes a frame and a rotary device arranged on the frame. The frame is provided with a loading and unloading station and a plurality of honing and reaming stations. The loading and unloading station is provided with a loading and unloading device, and the honing and reaming station is provided with a honing and reaming device. The rotary device includes a turntable 1 driven to rotate by a power device. A plurality of fixture assemblies for fixing the bushing 2 are circumferentially distributed on the turntable 1. Each fixture assembly enters each honing and reaming station in sequence from the loading and unloading station with the rotation of the turntable 1 and then returns to the loading and unloading station. The loading and unloading device includes a loading device, an unloading device, and a feeding device. The feeding device includes a cross slide 3.

[0044] The working principle of the present utility model: As shown in Figure 1As shown in the figure, the first driving device 5 drives the mounting plate 6 to rotate upward so that the clamping device faces the feeding device. The cross slide 3 drives the slider 4 to move downward, driving the clamping device to move downward to the feeding device. After the clamping device clamps the bushing 2 of the feeding device, the cross slide 3 drives the slider 4 to move upward, driving the clamping device to move upward. Then, the first driving device 5 drives the mounting plate 6 to rotate downward so that the clamping device faces downward. The cross slide 3 drives the slider 4 to move radially along the parallel turntable 1 to the fixture assembly at the loading and unloading station and then move downward. After the fixture assembly clamps the bushing 2, the clamping device releases the bushing 2. The power device drives the turntable 1 to rotate. The fixture assemblies at the loading station enter each honing station in sequence, and after being processed by the honing devices at each station, they return to the loading and unloading station. When the processed bushing 2 enters the loading and unloading station, the clamping device clamps the bushing 2 of the fixture assembly. The cross slide 3 drives the slider 4 to move upward, move radially along the parallel turntable 1, move downward to the unloading device. Finally, the clamping device releases the bushing 2, and the cross slide 3 drives the slider 4 to move upward, and so on.

[0045] As Figure 1 shown, the present utility model sets multiple honing stations in one device. The bushing 2 at the previous station is moved to the next station through the turntable 1. All honing processes of the bushing 2 can be completed through the device of the present utility model. The bushing 2 does not need to be transferred, there are few semi-finished products in the workshop, the occupied space and capital cost are low, and the production efficiency is high. At the same time, the present utility model only uses one station to complete loading and unloading, effectively saving the space on the turntable 1, so that more honing stations can be installed on the turntable 1.

The unloading device is a conveyor belt 10, and one end of the conveyor belt 10 is located below the clamping device.

[0052] Furthermore, the push rod 9 is arranged on the piston rod of a cylinder.

[0053] In order to load multiple bushings 2 at one time, the loading device further includes an inclined guide bar 11. A guiding groove 12 for placing the bushing 2 is provided in the guide bar 11. The lower end of the guiding groove 12 leads to the placing groove 8. The guide bar 11 is arranged on the side of the placing block 7, and on the other side of the placing block 7, there is a telescopic rod for pressing against the bushing 2 at the bottom end of the guiding groove 12. When there is no bushing 2 in the placing groove 8, the telescopic rod retracts, and the bushing 2 at the bottom end of the guiding groove 12 drops into the placing groove 8. Then the telescopic rod extends to press against the bushing 2 at the bottom end of the guiding groove 12 to prevent it from dropping. The present utility model arranges the guide bar 11 to place the bushing 2, eliminating the need to wait for loading and reducing the labor intensity of the operator.

[0054] Furthermore, the telescopic rod is the piston rod of a cylinder.

[0055] To prevent the unprocessed bushings 2 on the guide bar 11 from falling into the conveyor belt 10 and mixing with the processed bushings 2, a baffle 13 is provided above the conveyor belt 10.

The air enters the cavity 21 through the air inlet channel 22, expands the elastic membrane 20, and squeezes the elastic bushing 19. The elastic bushing 19 contracts to clamp the shaft sleeve. After the shaft sleeve 2 is processed, no air is introduced into the trachea. The elastic bushing 19 and the elastic membrane 20 reset under the action of elastic force, and squeeze the air in the cavity 21 into the air inlet channel 22 and the trachea, releasing the shaft sleeve 2. The reaming cutter can automatically find the center of the inner hole of the shaft sleeve 2 when it moves down to the shaft sleeve 2, with low requirements for the positional accuracy of the reaming cutter and the shaft sleeve 2, which is convenient for installation.
