Description

A turntable indexing mechanism in a tapered bearing assembly machine

technical field

The utility model belongs to the technical field of machinery and relates to a turntable indexing mechanism in a tapered bearing assembly machine.

Background technique

The tapered bearing assembly machine includes a rotating shaft, a turntable assembly and a bearing assembly module, the bearing assembly module includes a cage separation mechanism, and the cage separation mechanism includes a structure capable of taking out the cage.

The current turntable assembly is driven by a stepping motor, which has high requirements on the motor, which leads to a high cost of the motor, but in fact, it can be replaced by a mechanical indexing mechanism, which can save costs.

Contents of the invention

The purpose of this utility model is to solve the above-mentioned problems existing in the existing technology, and provide a turntable indexing mechanism in a tapered bearing assembly machine with relatively low cost.

The purpose of this utility model can be achieved through the following technical solutions:

A rotary table indexing mechanism in a tapered bearing assembly machine. The tapered bearing assembly machine includes a rotary table assembly and a rotating shaft. The indexing mechanism is arranged between the rotating shaft and the rotary table assembly. It is characterized in that the indexing mechanism includes a rotary sleeve and a driving shaft, the inside of the rotating sleeve is provided with a through installation hole that can be sleeved on the rotating shaft, the outer surface of the rotating sleeve is provided with a spiral groove, and the upper end of the driving shaft has a The connecting end of the turntable assembly described above is fixedly connected with several rollers on the side of the lower end of the drive shaft, and the rollers can rotate around their own axes, and the rollers are inserted into the spiral recesses. In the groove, and when the rotating sleeve rotates, the roller can roll along the side wall of the spiral groove.

In the above-mentioned turntable indexing mechanism in a tapered bearing assembly machine, there are 4 to 8 rollers, the number of which corresponds to the number of workpiece positioning cylinders on the turntable assembly.

In the above-mentioned turntable indexing mechanism in a tapered bearing assembly machine, the lower end of the drive shaft has a disc protruding radially outward, and the roller is fixed on the disc , and the axis of the roller is perpendicular to the axis of the drive shaft, and the rollers are evenly distributed along the circumference of the drive shaft.

Compared with prior art, the utility model has the following advantages:

1. This device drives the turntable assembly by connecting the rotating sleeve and the driving shaft. When the rotating shaft transmits power to the rotating sleeve to make the rotating sleeve rotate, the driving shaft rotates sequentially through the engagement of the spiral groove and the roller. An angle, so as to achieve the purpose of precise indexing of the turntable, the structure of this device is simple, and the cost is much lower than that of expensive stepping motors.

Description of drawings

Fig. 1 is a structural schematic diagram of the turntable indexing mechanism in the embodiment.

In the figure, 1. Rotary sleeve; 2. Drive shaft; 3. Mounting hole; 4. Spiral groove; 5. Connecting end; 6. Roller.

Detailed ways

The following are specific embodiments of the utility model and in conjunction with the accompanying drawings, the technical solution of the utility model is further described, but the utility model is not limited to these embodiments.

As shown in Figure 1, the tapered bearing assembly machine includes a turntable assembly and a rotating shaft, the indexing mechanism is arranged between the rotating shaft and the turntable assembly, the indexing mechanism includes a rotary sleeve 1 and a drive shaft 2, inside the rotary sleeve 1 There is a through mounting hole 3 that can be sleeved on the rotating shaft. The outer surface of the rotating sleeve 1 is provided with a spiral groove 4. The upper end of the driving shaft 2 has a connecting end 5 that can be fixedly connected with the turntable assembly. The driving shaft 2 There are several rollers 6 fixed on the lower end side of the shaft. The rollers 6 can rotate around their own axes. The groove 4 side walls roll. There are 4 to 8 rollers 6, corresponding to the quantity of the workpiece positioning cylinders on the turntable assembly. The lower end of the drive shaft 2 has a disc protruding radially outwards, the roller 6 is fixed on the disc, and the axis of the roller 6 is perpendicular to the axis of the drive shaft 2, and the roller 6 moves along the axis of the drive shaft. 2 evenly distributed around the circumference.

The specific embodiments described herein are only examples to illustrate the spirit of the present invention. Those skilled in the technical field to which the utility model belongs can make various modifications or supplements to the described specific embodiments or adopt similar methods to replace them, but they will not deviate from the spirit of the utility model or go beyond the appended claims defined range.
