Problems solved by technology
At present, the work of inserting the rack support bushing into the bushing slot of the housing is manually installed by the staff using auxiliary tools. During the assembly of the bushing, since the bushing slot of the steering gear housing is a step groove, and the circumference of the lower end of the bushing is a stepped boss corresponding to the slot of the bushing, which can only ensure that the depth dimension of the bushing in the axial direction meets the assembly requirements, and cannot guarantee the assembly in place in the radial direction. The stepped boss of the sleeve is squeezed into the slot of the steering gear housing, resulting in a long time required for the assembly of each workpiece, making the assembly work efficiency low, and the assembly quality of the bush cannot be strictly guaranteed; at the same time, due to the product There are differences in the specifications and sizes of the bushings and the ability of the staff. Manually assembling the bushing is prone to trimming or damage to the bushing during assembly, resulting in a certain loss rate. Therefore, it is necessary to improve it

Embodiment Construction
[0034] The method for assembling the housing bushing of the rack and pinion steering gear by using a press-fitting device includes the following steps:
[0035] First, the bushing 1 is set on the limit head 2 of the assembly device. The assembly device includes a frame 3, a working panel 4, an upper press-fitting cylinder 5, a lower lifting cylinder 6 and a press-fitting tube 7, the frame 3 is provided with a working panel 4, and the working panel 4 is fixedly equipped with a press-fitting tube 7, The press-fit tube 7 is in the shape of "⊥", and the press-fit tube 7 is fixedly installed on the upper surface of the working panel 4 through the fixing bolt. Between 7, a return spring 10 is installed through a spring seat 9, and a press tube 11 is movably installed on the press tube 7 above the spring seat 10. The press-fit cylinder 11 is a cylinder with open ends at both ends, the lower port of the press-fit cylinder 11 is flared (bell mouth), and the upper port of the press-fit...

The invention relates to a method for assembling a rack and pinion steering gear casing bushing by using a press-fitting device, which belongs to the technical field of steering gear installation. In the present invention, the bushing is fitted in the slot of the steering gear housing through the cooperation of the press-fitting cylinder and the pressing tube, and the boss of the bushing is accurately squeezed into the steering gear housing through the cooperation of the expanding rod and the extrusion head. In the card slot corresponding to the boss on the body, the efficiency of the assembly operation is effectively improved; the product quality is guaranteed, and it is avoided that due to differences in product structure, size and the ability of the staff, manual bushing installation is very easy to cause the bushing The sleeve is trimmed or damaged during assembly, causing a certain loss rate problem. It is of positive significance to improve the assembly quality of products.
Description
technical field [0001] The invention relates to a method for assembling a bushing of a steering gear casing by using a press-fitting device, which belongs to the technical field of steering gear installation. Background technique [0002] The rack and pinion steering gear is widely used in the steering gear system of small displacement cars and new energy vehicles because of its simple and compact structure, high quality and low price. When the rack and pinion steering gear is assembled, the shell bushing needs to be inserted into the gear The bushing slot of the rack steering gear housing. At present, the work of inserting the rack support bushing into the bushing slot of the housing is manually installed by the staff using auxiliary tools. During the assembly of the bushing, since the bushing slot of the steering gear housing is a step groove, and the circumference of the lower end of the bushing is a stepped boss corresponding to the slot of the bushing, which can only e...
