Description

Technical Field

[0001] The utility model relates to a tool, in particular to a retaining ring assembly device for a thrust rod hole. Background Art

[0002] Currently, commercial vehicle suspension systems, after using coil springs and other elastic elements to withstand vertical loads, require a guide mechanism consisting of additional transverse and longitudinal thrust rods, reinforcement rods, and shock absorbers, ultimately connecting the left and right wheels together through a single, integrated axle. The rear end of the longitudinal thrust rod and the front end of the axle are hinged to the vehicle frame. The transverse thrust rod is hinged to the vehicle body at one end and to the axle at the other. During operation, the springs withstand vertical loads, while the longitudinal and transverse forces are borne by the longitudinal and transverse thrust rods, respectively. When the wheels bounce, the entire axle swings around the hinge points of the longitudinal and transverse thrust rods on the vehicle body. Rubber bushings at these hinge points eliminate motion interference caused by axle swing.

[0003] However, the rubber bushing of the thrust rod is elastic and needs to be locked with a hole retaining ring after assembly to control the rubber bushing in a certain compression state, so that the rubber bushing and the thrust rod assembly part generate friction through extrusion to prevent rotation caused by external forces. Because the rubber bushing and the vehicle body have relative position requirements, the installation handle of the rubber bushing needs to be set according to a predetermined angle during the assembly process to ensure vehicle matching. Therefore, to achieve the above structure, when assembling the thrust rod, rubber bushing, and hole retaining ring, it is necessary to first position the rubber bushing using an angle control device, and then press the rubber bushing into the thrust rod assembly space using a hydraulic press or other equipment. While keeping the rubber bushing in a compressed state, the hole retaining ring is manually placed using circlip pliers and pressed in a second time, thereby realizing the hole retaining ring locking function on the rubber bushing. However, the above production efficiency is low and the labor intensity is high. There is an urgent need for a convenient hole retaining ring assembly device. Utility Model Content

[0004] In order to solve the above problems, the purpose of the utility model is to provide a thrust rod hole retaining ring assembly device.

[0005] To achieve the above-mentioned purpose, the technical solution of the present invention is: a retaining ring assembly device for a thrust rod hole, comprising a positioning block and a connecting plate located above the positioning block, a guide block is provided on the upper surface of the positioning block, a vertical positioning shaft passes through the guide block and the positioning block in sequence from top to bottom, and the lower part of the positioning block is a cylindrical structure, the positioning shaft is elastically supported by a telescopic spring in the cylindrical structure of the positioning block, and is sleeved on the positioning shaft, the upper end of the supporting positioning shaft is located in the guide block, and a positioning groove is provided, a fixed column and a movable column are fixed in sequence on the lower surface of the connecting plate, a tightening block is fixed to the lower end of the connecting block, the connecting block and the tightening block are elastically slidably arranged at the lower end of the movable column, the inner cavity of the tightening block is provided with a conical tightening cavity, and a positioning boss structure is provided on the periphery of the lower end opening.

[0006] Furthermore, the inner cavity of the movable column is provided with a central pressure column that can move up and down, and a rebound spring is sleeved on the central pressure column. The lower end of the rebound spring is supported on the outward-protruding boss of the lower side wall of the central pressure column, and the upper end is supported on the top of the inner cavity of the fixed column.

[0007] Furthermore, a positioning plate is fixed to one side of the positioning block, and a fixing groove for connecting the device is provided on one side of the positioning plate.

[0008] Furthermore, a positioning arm opposite to the positioning plate is provided on the other side of the positioning block, and the outer end of the positioning arm is bent upward and provided with a contoured groove.

[0009] Furthermore, a hollow buffer opening is provided on one side of the connection portion between the tightening block and the connecting block.

[0010] Furthermore, long strip-shaped equipment fixing grooves are respectively provided on both sides of the connecting plate.

[0011] Furthermore, the movable column is fixedly connected to the lower end of the fixed column through a threaded structure.

[0012] Through the above configuration, the beneficial effects of the present invention are:

[0013] ① The coordination of the positioning device (i.e., the positioning block) and the guide device (i.e., the guide block) enables accurate positioning of the thrust rod while effectively controlling the angular dimensions of the rubber bushing, resulting in smoother operation. The guide device effectively improves the angular dimensional accuracy of the rubber bushing during lathing while also ensuring that the rubber bushing and the outer cavity, which could be caused by misalignment during assembly, are not interfered with, thus preventing damage.

[0014] ② During the downward pressing process of the equipment, the pressing device (i.e. the fixed column and movable column parts) and the tightening device (i.e. the tightening block part) can realize the pre-pressing of the rubber bushing, reducing the pressing process once. At the same time, the tightening device is linked to adjust the size of the preset hole retaining ring and release it at the set position to lock the compressed rubber bushing, replacing the manual use of circlip pliers to install the hole retaining ring. The operation is simple and the labor intensity is reduced. BRIEF DESCRIPTION OF THE DRAWINGS
