Description

Technical Field

[0001] The utility model relates to a tool, in particular to a universal assembly tool for rubber nodes. Background Art

[0002] The rubber node is formed by vulcanizing the core shaft and the outer sleeve into one piece. It is an important connecting element between the axle box swing arm and the frame of the rail vehicle. It is widely used in urban rail vehicles such as subways and light rails and high-speed trains. The rubber node is responsible for transmitting the longitudinal force of traction or braking, ensuring the stable operation of the train and having good guiding capabilities. Since the rubber node for rail transit needs to be assembled with the traction rod body, the product interface size requirements are relatively strict, and the installation angle requirements for the rubber node are relatively high. Usually, the planes at both ends of the core shaft of the rubber node are deflected at an angle from the center line of the installation holes at both ends of the traction rod body.

[0003] Most of the existing assembly tools process assembly positioning blocks 11 at different angles for rubber nodes at different angles, and different positioning block connecting rods 12 need to be processed for traction rod bodies with different center distances, such as Figure 1 This type of tooling is prone to angle deviation after assembly and has poor versatility, and is not suitable for installing rubber nodes of various angles. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a universal assembly tool for rubber nodes which has accurate installation angle, good versatility and can improve production efficiency.

[0005] In order to solve the above problems, the utility model adopts the following technical solutions:

[0006] A universal assembly tool for rubber nodes, comprising a bottom plate, a fixed support sleeve and a movable support sleeve are respectively arranged near both ends of the bottom plate, the fixed support sleeve is fixedly connected to the bottom plate, the movable support sleeve is slidably connected to the bottom plate, angle adjustment rings are respectively installed at the lower ends of the fixed support sleeve and the movable support sleeve through clearance fit, a lever is fixed at the outer edge of the angle adjustment ring, and the lever is respectively led out from fan-shaped notches arranged at the lower ends of the fixed support sleeve and the movable support sleeve;

[0007] An angle plate is provided on the fixed sleeve at the outer edge of the lower end of the fixed support sleeve and the movable support sleeve, and an angle scale line is provided on the angle plate for cooperating with the lever to adjust the angle of the angle adjustment ring;

[0008] Guide columns are symmetrically fixed on the angle adjustment ring, and springs are respectively sleeved on the guide columns. Positioning sleeves are respectively installed on the upper ends of the fixed support sleeve and the movable support sleeve through clearance fit. A positioning hole that matches the core shaft end of the rubber node is provided in the center of the positioning sleeve. The upper end of the guide column is plugged into the corresponding positioning sleeve for positioning the traction rod and rubber node to be assembled.

[0009] As a further preference, two strip holes are symmetrically provided on the bottom plate corresponding to one end of the movable support sleeve, and two bosses are symmetrically provided on the bottom surface of the movable support sleeve and are respectively inserted into the corresponding strip holes through sliding fit.

[0010] As a further preference, the outer diameter of the positioning sleeve is matched with the mounting hole clearance at both ends of the traction rod, and in the initial state, the upper end surface of the positioning sleeve is higher than the upper end surfaces of the fixed support sleeve and the movable support sleeve to facilitate positioning of the traction rod to be assembled.

[0011] As a further preference, the lever is fixed radially to the lower end of the outer edge of the angle adjustment ring, and a groove is provided on the outer end of the lever, which corresponds to the angle scale line on the angle disk to accurately adjust the angle.

[0012] As a further preference, the central angle corresponding to the fan-shaped notch is 180 degrees.

[0013] The beneficial effects of the utility model are:

[0014] 1. Since a fixed support sleeve and a movable support sleeve are respectively provided near both ends of the bottom plate, the fixed support sleeve is fixedly connected to the bottom plate, and the movable support sleeve is slidably connected to the bottom plate, the traction rod to be assembled is supported by the fixed support sleeve and the movable support sleeve, so that the assembly of traction rods with different center distances and rubber nodes can be realized, and the versatility is good. When installing traction rods with different center distances, there is no need to replace tooling, which can improve production efficiency.

[0015] 2. Angle adjustment rings are installed at the lower ends of the fixed support sleeve and the movable support sleeve through clearance fit, and angle plates are provided on the fixed sleeves at the outer edges of the lower ends of the fixed support sleeve and the movable support sleeve. The angles of the angle adjustment ring and the positioning sleeve can be adjusted by cooperating with the lever fixed on the outer edge of the angle adjustment ring and the angle plate, thereby adjusting the installation angle of the rubber node. The installation angle is precise, and the rubber node can be adjusted to different angles for precise press-fitting. BRIEF DESCRIPTION OF THE DRAWINGS
