[0023] Example

[0024] like Figure 1-5As shown, an embodiment of the utility model proposes a connecting rod bushing press-fitting device for automobiles, comprising a base 1 and a fixing seat 2. The connecting rod bushing press-fitting device for automobiles designed in this scheme solves the problem of misalignment affecting the press-fitting quality when the connecting rod and the bushing are press-fitted through a matching design, and can be used for the press-fitting of connecting rods and bushings of different sizes. A fixing seat 2 is fixedly connected to one side of the base 1, a pressing part 3 is matched with the top of the base 1, the pressing part 3 is matched with an anti-misalignment part 4, and the anti-misalignment part 4 is matched with the bottom of the base 1, and a clamping part 5 is symmetrically matched on the fixing seat 2. The pressing part 3 is composed of a cylinder 301, a pressing mounting plate 302, a movable groove 303, a first screw rod 304, a motor 305 and an inner support resistance block 306. The cylinder 301 is movable A pressing and mounting disk 302 is fixedly connected to the plug rod, and three movable grooves 303 are opened in a circular array of the pressing and mounting disk 302. A first screw rod 304 is rotatably connected in the movable groove 303, and one end of the first screw rod 304 is fixedly connected to a motor 305, and the motor 305 is fixedly connected to the outer ring of the pressing and mounting disk 302. An inner support block 306 is threadedly connected to the first screw rod 304, and the inner support block 306 is slidably connected in the movable groove 303. The device is electrically connected to an external control device through a conductive line, and the operating state of the device is controlled by the external control device. When the connecting rod is press-fitted with a bushing, the connecting rod is first placed on the base 1 so that the press-fitting port of the connecting rod is at the center of the base 1, so that the rod body of the connecting rod is between two The second screw rod 501 is rotated by the operation of the motor 502, so that the clamping block 503 threadedly connected to the second screw rod 501 can be adjusted in translation and sliding in the sliding groove 202, so that the two clamping blocks 503 clamp and fix the rod body. At this time, the inner support block on the anti-misalignment component 4 is supported at the press-fitting port of the connecting rod. By supporting the port of the connecting rod, the press-fitting port of the connecting rod can be located at the center of the base 1. The center of the pressing and holding mounting plate 302 is also located at the center of the base 1. The bushing is taken and placed at the position of the three retracted inner support abutment blocks 306. Then, the first screw rod 304 is rotated by the operation of the motor 305, so that the threaded connection on the first screw rod 304 and the sliding connection in the moving The inner support abutment block 306 in the movable groove 303 performs inner support extraction on the inner wall of the bushing. At this time, the bushing is accurately aligned at the press-fitting port of the connecting rod through the downward pressure of the cylinder 301. When the bushing is accurately press-fitted at the port of the connecting rod, as the cylinder 301 is pressed downward, the cylinder on the anti-misalignment component 4 will shrink, and along with the operation of the motor on the anti-misalignment component 4, the inner support clamping of the port of the connecting rod by the inner support block on the anti-misalignment component 4 will loosen. When the pressing and holding mounting plate 302 abuts against the edge of the press-fitting port of the connecting rod, the cylinder at the anti-misalignment component 4 is in a fully contracted state, and the abutment block at the anti-misalignment component 4 is below the adjusting groove 101, which will not affect the perfect press-fitting use of the bushing. The upper end of the bushing is pressed and held by the pressing and holding mounting plate 302.The bushing can be completely press-fitted into the press-fitting port of the connecting rod, and then the motor 305 is running to rotate the first screw rod 304, so that the inner support abutment block 306 clamping the bushing inner support is loosened, and the cylinder 301 is lifted to meet the next press-fitting use. Through the matching design, it can ensure that there will be no misalignment when the bushing and the connecting rod are press-fitted, which will lead to the problem of unsuccessful press-fitting, and improve the applicability of the device.
