Description

Technical Field

[0001] The utility model relates to a manual press-fitting machine for assembling a bushing for an automobile, and belongs to the technical field of mechanical parts assembly. Background Art

[0002] Bushings are parts that are often used to fill gaps between parts. Bearings are parts that support rotating shafts. Friction is inevitable in the parts that support rotating shafts. In order to reduce this friction, bearings must be used to keep the rotating shaft in the correct position. Self-lubricating bushings are bearings that do not require lubrication, that is, they can operate without adding lubricating oil. They are also called oil-free bearings. Self-lubricating bushings have lubricating oil adsorbed or solid lubricants embedded in the bearing body, so they are sliding bearings with a structure of "self-lubricating use" or "reduced number of lubrication times". The characteristics of self-lubricating bushings can be roughly summarized as follows: no lubricating oil is required, and by using self-lubricating materials, there is no need to supply lubricants to the friction surface, and maintenance-free. Although there are self-lubricating bushings that are appropriately lubricated to increase bearing life and reduce friction coefficients, in principle, self-lubricating bushings can be used in a dry, non-lubricated state. Rotation and linear motion can be achieved at the same time. Due to the matching structure of the shaft and the hole, linear motion in the axial direction and rotation around the axis can be achieved at the same time. In addition, the required functions can be achieved in a compact form with the minimum required space. Affordable cost. The mechanical components consist of only two parts, the shaft and the bushing, with a small number of parts. The lubricating material is a metal material that can be mass-produced, so the cost is acceptable. In addition, since no lubricant is required, maintenance costs can be reduced, which can reduce investment costs and man-hours.

[0003] The Chinese utility model patent discloses a simple manual stamping device named as CN205110484U, and its structure is described as comprising a first linear guide shaft 1, a second linear guide shaft 2, a toggle clamp 3, a first oil-free bushing fixing seat 4, a second oil-free bushing fixing seat 5, a base 6, and a pressing plate 7, wherein the toggle clamp 3 is connected to the support rod of the base 6, the lower end of the toggle clamp 3 is connected to the pressing plate 7, and the two ends of the pressing plate 7 are respectively connected to the first linear guide shaft 1 through the first oil-free bushing fixing seat 4, and connected to the second linear guide shaft 2 through the second oil-free bushing fixing seat 5. When working, the toggle clamp 3 is manually controlled to adjust the pressing plate 7 to move up and down to perform simple stamping on the workpiece.

[0004] The disadvantage of this patent is that the elbow clamp 3 is manually pushed and clamped, and the pressure plate 7 is pushed downward for press-fitting. This structure is not conducive to batch assembly of bushings. The manual push clamp requires manual up and down pushing. Large-scale assembly of bushings requires manual frequent removal of bushings, which increases the fatigue of operators and increases the labor intensity of operators. Summary of the invention

[0005] In order to solve the problems existing in the prior art, the purpose of the utility model is to provide a manual press machine for assembling automobile bushings.
