Description

Bearing assembly tooling

technical field

The utility model relates to a bearing assembly tool.

Background technique

When mounting bearings on shafts, larger bearings usually require a press for assembly. However, if the two ends of the shaft need to be installed with bearings and bearing housings, the bearing at one end of the shaft should be assembled first, and then the assembled shaft and bearings should be removed from the press table, and another bearing should be put on after turning over the shaft. And the bearing seat, and then move to the press workbench, carry out the assembly of another bearing and the bearing seat, its assembly efficiency is low, and move the shaft and the bearing seat repeatedly, time-consuming and laborious, the labor intensity of the worker is big.

Utility model content

The purpose of this utility model is to provide a bearing assembly tool to solve the problem of low assembly efficiency when using a press to assemble bearings at both ends of a shaft workpiece.

The technical solution of the utility model is: a bearing assembly tool, including a frame and a pressure mechanism installed on the frame, the frame includes a bottom plate, and the bottom plate is vertically fixed with brackets on both sides opposite to the workpiece installation position , the tops of the two brackets are respectively provided with relatively parallel guide rods, a support beam is slidably mounted on the two guide rods, and the pressure mechanism is vertically fixed in the middle of the support beam.

At the workpiece installation position, a groove is dug on the upper end surface of the bottom plate corresponding to the pressure mechanism for limited cooperation with the shaft workpiece to be assembled.

The support is a door-shaped support, and the door-shaped support is composed of two relatively spaced columns and a beam fixed on the top of the two columns.

The two ends of the upright column are respectively screwed with adjusting nuts which are used to adjust the height of the crossbeam and cooperate with the bottom plate and the crossbeam in a limited position.

The guide rods are fixedly installed on the lower part of the corresponding beams through the connecting plates correspondingly arranged at both ends.

The pressure mechanism is a hydraulic pressure mechanism. The hydraulic pressure mechanism includes a cylinder body and a piston push rod protruding axially downward. The cylinder body is fixedly clamped in a clamp corresponding to the center of the support beam.

In the utility model, the pressure mechanism used for pushing the bearing is slidably assembled on the corresponding two guide rods through the support beam, so that it can slide laterally within the length range of the two guide rods. When installing the bearing, after the bearing at one end is pressed, slide the pressure mechanism to one side of the bracket through the guide rod, and then turn the shaft workpiece directly on the bottom plate, and then slide the pressure mechanism to the original position to realize the bearing at the other end. During the assembly of the bearing seat, there is no need to move the assembly parts back and forth during the entire assembly process, which not only improves the assembly efficiency of the bearing, but also reduces the labor intensity of workers.

Description of drawings

Fig. 1 is a structural schematic diagram of a specific embodiment of the bearing assembly tool of the present invention.

Detailed ways

The specific embodiment of the bearing assembly tool of the present utility model is shown in Figure 1. The assembly tool includes a base plate 1, and two brackets arranged in parallel at opposite intervals are vertically arranged on the opposite sides of the base plate 1. In this embodiment, each bracket They are all door-shaped brackets, and each door-shaped bracket is composed of two vertical columns 2 arranged in parallel at opposite intervals and a crossbeam 10 fixedly installed on the top of the corresponding two vertical columns 2 in the transverse direction. A guide rod 11 is respectively fixed parallel to the lower parts of the two beams, and the guide rod 11 is installed on the corresponding beam through connecting plates correspondingly arranged at both ends thereof. A support beam 5 is slidably mounted on the two guide rods 11, and the middle part of the support beam 5 is equipped with a hydraulic push rod 9 through a vertical fixing clip of a corresponding clamp 6. The hydraulic push rod 9 can be directly applied to a conventional hydraulic cylinder used to draw the hydraulic tension of the bearing. During use, the cylinder body of the hydraulic cylinder is clamped and fixed by the clamp 6, and the piston rod of the hydraulic cylinder is vertically downward.

Because the lengths of various shaft workpieces are not equal, if the length of the piston rod on the hydraulic cylinder alone cannot be used to top-mount the bearing in place, in this embodiment, the upper and lower ends of the above-mentioned columns 2 are respectively adjusted by adjusting nuts 3, 4. Assembled with the corresponding crossbeam 11 and the bottom plate 1. When it is necessary to adjust the height of the hydraulic push rod 9, the position of the corresponding crossbeam 11 can be adjusted by adjusting the adjustment nuts at the upper and lower ends of each column 2, so as to realize the adjustment of the hydraulic push rod. 9 position adjustment.

In order to facilitate the positioning of the shaft workpiece when assembling the bearing and ensure the vertical state of the shaft workpiece, in this embodiment, a rectangular groove with a depth of about 5 mm is dug at the corresponding position on the upper end surface of the bottom plate 1 as the workpiece installation position. , When in use, use the bottom surface and one side of the groove to locate the shaft workpiece. For bearings with a large amount of interference, an additional V-shaped block can be added for positioning.
