[0025] By placing the automobile parts on the transmission device 21 in reverse, the transmission device 21 drives the parts to move to the right, and then the parts will fall into the receiving rack 24 through the guide plate 22.

[0026] The bushing loading assembly 3 includes a vertical plate 31 arranged on the top rear side of the base plate 1, a hydraulic rod 32 is arranged on the top of the front of the vertical plate 31, the telescopic end of the bottom of the hydraulic rod 32 is located above the processing frame 23, and a discharge frame 33 is arranged on the front of the vertical plate 31.

[0027] A first telescopic rod 25 is rotatably provided on the inner side of the processing frame 23, and the telescopic end at the top of the first telescopic rod 25 is rotatably connected to the right side of the material receiving frame 24. An infrared sensor is provided on the inner side of the material receiving frame 24. A placement seat 26 is provided on the top of the base plate 1 and at the bottom of the processing frame 23. Two sliding frames 27 are horizontally provided on the top of the placement seat 26 in the front and rear directions. A placement box 28 is provided on the top of the two sliding frames 27 so as to slide left and right along the length direction thereof.

[0028] When the infrared sensor detects that there are accessories inside the receiving rack 24 , the transmission device 21 is first stopped, and then the first telescopic rod 25 is retracted to flip the receiving rack 24 , so that the accessories are upright and located on the left side of the top of the processing rack 23 .

[0029] Two clamping frames 29 are slidably arranged on the inner side of the placement box 28 in a mirror-image manner. The top opposite sides of the two clamping frames 29 are located on the top of the processing frame 23.

[0030] By moving the placement box 28 to the left, when the two clamping frames 29 clamp the accessories, the placement box 28 moves to the right again and places the accessories at the bottom of the processing position of the hydraulic rod 32. During processing, the placement box 28 will reset to the left. After processing, the placement box 28 will drive another accessory to be processed to move to the right. At the same time, the other clamping parts of the two clamping frames 29 will drive the processed accessories to move to the right, so that they will eventually fall into the collection box on the top right side of the bottom plate 1.

[0031] A first rotating screw 4 is laterally rotatably arranged at the top of the placement seat 26 and on the side opposite to the two sliding frames 27. A first motor 5 for driving the first rotating screw 4 is arranged inside the placement seat 26. The right end of the first rotating screw 4 is connected to the output end belt on the right side of the first motor 5.

[0032] The rotation of the output end of the first motor 5 drives the rotation of the first rotating screw 4, and then drives the placement box 28 to move to one side on the top of the placement seat 26. The rotation direction of the first motor 5 can be adjusted in advance so that the placement box 28 can meet the timing of moving left and right.

A second motor 7 for driving the second rotating screw rod 6 to rotate is arranged at the bottom of the inner wall of the placement box 28, and the output end on the back side of the second motor 7 is meshed with the peripheral side surface of the second rotating screw rod 6 through a set of gears.

[0034] The rotation of the output end of the second motor 7 drives the rotation of the gear and then drives the rotation of the second rotating screw 6, so that the two clamping frames 29 move relative to or away from each other.

[0035] The bushing loading assembly 3 also includes a second telescopic rod 34 arranged on the right side of the inner wall of the discharge frame 33 , a discharge fork 35 is arranged at the telescopic end on the left side of the second telescopic rod 34 , and a storage pipe 36 is connected to the top of the discharge frame 33 .

[0036] By placing the required bushing into the storage tube 36, each time the second telescopic rod 34 is extended, a bushing will be driven to move to the left and finally fall onto the accessory that is already in place. The bushing is pressed into the accessory by extending the telescopic end of the hydraulic rod 32 to achieve overall press-fitting. Since the placement of the accessory and the drop point of the bushing are fixed, the bushing will not be offset and unable to be pressed in.

[0037] The working principle of the press-fitting equipment for automobile bushings provided by the utility model is as follows:

[0038] Step 1: When in use, the accessory is placed on the top of the transmission device 21 in reverse, and the transmission device 21 drives the accessory to move to the right, and finally falls on the receiving rack 24 through the guide plate 22. The infrared sensor receives a signal, so that the first telescopic rod 25 retracts to flip the receiving rack 24 and the accessory, so that the accessory is placed upright and located on the top of the processing rack 23;

[0039] Step 2: The placement box 28 moves to the left through the rotational cooperation of the output ends of the first motor 5 and the second motor 7. After the two clamping frames 29 clamp the accessories, the placement box 28 moves to the right again and places the accessories at the bottom of the processing position of the hydraulic rod 32. During processing, the clamping frame 29 releases the accessories and the placement box 28 is reset to the left. After processing, the placement box 28 drives another accessory to be processed to move to the right. At the same time, the other clamping parts of the two clamping frames 29 drive the processed accessories to move to the right, so that they finally fall into the collection box on the top right side of the bottom plate 1.

[0040] Step 3: When the accessory is moved, the discharging fork 35 is driven by the extension of the second telescopic rod 34 to move a bushing to the left and finally drop it into the top of the accessory, and then the bushing is pressed into the interior of the accessory by the extension of the telescopic end of the hydraulic rod 32 to complete the overall press-fitting. The structure is compact and automatic feeding of the device is realized. While improving the press-fitting efficiency, it also avoids the safety hazards caused by manual material replacement.

[0041] Compared with the related art, the press-fitting equipment for automobile bushings provided by the utility model has the following beneficial effects:

[0042] Through the cooperation of the accessory feeding assembly 2 and the bushing feeding assembly 3, every time an accessory is pressed and installed, the subsequent accessories to be processed will be continuously fed in and processed, and the processed automotive accessories will be gradually discharged and collected. The device greatly improves the pressing efficiency of the pressing equipment and avoids safety hazards caused by manual material replacement.

[0043] Finally, it should be pointed out that the above embodiments are only representative examples of the present utility model.
