Background

Wind power generation has been developed rapidly in recent years due to its advantages of no pollution, low construction cost, and the like. The processing efficiency of the internal parts of the gear box plays a crucial role. The gear transmission in the gear box is mainly divided into parallel stage gear transmission and planetary stage gear transmission. The planet carrier is one of the main components of the planetary gear transmission device, and the planet wheel shaft or the bearing is arranged on the planet carrier. The machining precision of the planet carrier can directly influence the meshing between the planet stage gears, so the machining precision of the planet carrier plays an important role. The planet carrier can use various processing tools in the processing process.

At present, when the axle diameter and the inner hole of the short head side of a planet carrier are finely turned, three equal-height blocks with independent fixed heights are usually used for supporting the large end face of the long head side of the planet carrier, the axle diameter of the long head of the planet carrier is clamped by a movable clamping jaw, and after clamping and positioning, the axle diameter and the inner hole of the short head side of the planet carrier are finely turned;

the axial dimension from the long head end face of the planet carrier to the shaft diameter end face of the long head provided by designers in the prior art supports the large end face of the long head side of the planet carrier in a mode of raising with equal height blocks, and the height adjustment needs to be adjusted through a jack.

The disadvantages of the prior art are as follows:

1. when the planet carriers of different machine types are processed, equal-height blocks with different heights need to be manufactured in advance, and the universality is not strong, so that the processing cost is high;

2. the height is adjusted by a jack, the contact position between the equal-height block and the planet carrier needs to be adjusted by packing paper, and the jack needs to be placed on the equal-height block with a certain height and is not stable enough;

3. when the equal-height blocks with fixed height are clamped, the efficiency is low when the parts are clamped and corrected on a machine tool, and the time is consumed for adjusting.

As shown in fig. 1:

the utility model relates to a clamping tool with adjustable height for finish turning of the shaft diameter and the inner hole of the short head side of a planet carrier.

The planet carrier 2 is placed on the machine tool workbench 1, and the long head side shaft diameter of the planet carrier 2 is clamped and fixed through a machine tool clamp 8 of the machine tool.

The tool upright column 3 and the tool pressing plate 4 are fixedly connected through welding.

T type bolt 6 passes T type groove 11 on the lathe workstation 1 to after T type bolt 6 passed the through-hole on the frock clamp plate 4, the spiral shell of round nut 5 was established on T type bolt 6 and is compressed tightly frock clamp plate 4, thereby frock clamp plate 4 is fixed on lathe workstation 1, consequently frock stand 3 is fixed on lathe workstation 1, and frock clamp plate 4 and frock stand 3 can adjust suitable position through removing in T type groove 11 before fixed.

The upper end face of the tooling upright post 3 is provided with a threaded hole 31 with a certain depth, and the tooling bolt 7 is connected with the tooling upright post 3 by screwing into the threaded hole 31. The head of the tooling bolt 7 is semicircular and abuts against and contacts with the large end surface 21 of the long head side of the planet carrier 2 in a point contact manner.

The end face of the workpiece needs to be calibrated before machining of the planet carrier 2, and the height of the tooling bolt 7 is controlled by adjusting the screwing depth of the tooling bolt 7.
