Description
Technical Field
The utility model relates to the field of tools, in particular to a clamping tool for processing a long-head shaft diameter of a wind power gear box planet carrier on a vertical lathe.
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. Various machining tools can be used in the machining process of the planet carrier, for example, a clamping tool for finish turning of the long-head side shaft diameter and the inner hole of the planet carrier.
At present, when the axle diameter and the inner hole of the long head side of a planet carrier are finish turned, three equal-height blocks with independent fixed heights are usually used for supporting the large end face of the short head side of the planet carrier, the large outer circle of the short head side of the planet carrier is clamped by a movable clamping jaw, and the axle diameter and the inner hole of the long head side of the planet carrier are finish turned after the large end face of the long head side is clamped and positioned by a pressing plate;
the axial dimension from the long head end face of the planet carrier to the long head shaft diameter end face provided by designers in the prior art supports the large end face of the short head side of the planet carrier in a mode of padding with equal-height blocks, and the height of the planet carrier needs to be adjusted by a jack. After the distance from the long-head side large end face of the planet carrier to the short-head shaft diameter end face of the planet carrier is calculated, a tool screw with a certain height is matched, and the long-head side large end face of the planet carrier is pressed in a mode of tightening a nut to press a pressing plate.
The prior art has the following disadvantages:
1. when the planet carriers of different types are processed, equal-height cushion 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, and the contact position of the equal-height block and the planet carrier needs to be adjusted by packing paper, so that the adjustment difficulty is high;
3. when the equal-height iron with fixed height is clamped, the efficiency is low when the part is clamped and corrected on a machine tool, and the adjustment consumes time.
4. The process reference of the end face of the long head side of the planet carrier is easy to deform due to stress caused by the compression of the large end face of the long head side, so that the calibration data is not accurate enough, and the precision of finish turning of the whole workpiece and the coaxiality of the shaft diameters of two sides are visualized.

As shown in fig. 1 and 2:
the tool provided by the utility model is mainly suitable for the requirement of processing the shaft diameter of the single planet carrier 2 on the finish turning long head side 22 of the vertical lathe.
The carrier 2 is placed on the machine table 1 with its short end 21 facing downward for machining.
The shaft diameter of the planet carrier 2 is clamped and fixed by a machine tool clamp 3 of the machine tool.
The three jacks 7 are uniformly arranged on the machine tool workbench 1 relative to the axis circumference of the shaft hole 20 of the planet carrier 2, and the heads of the jacks 7 prop against the large end surface 23 on the short head side of the planet carrier.
The tooling pressing plate 6 is placed on the inner cavity end face 25 of the planet carrier short-head side pin shaft hole 24, the tooling pressing plate 6 covers the planet carrier short-head side pin shaft hole 24, and the tooling pressing plate 6 is provided with a strip-shaped hole 61 as an installation through hole.
The T-shaped bolt 4 passes through a T-shaped groove 11 on the machine tool workbench 1, then passes through a short-head side pin shaft hole 24 of the planet carrier, then passes through a strip-shaped hole 61 of the tool pressing plate 6, and then the pressing nut 5 is screwed on the T-shaped bolt 4 and presses the tool pressing plate 6 tightly,
the planet carrier 2 generally has 3 planet carrier stub side pin shaft holes 24, has three sets of T type bolts 4, frock clamp plate 6, gland nut 5, and three frock clamp plate 6 is pressed respectively on the inner chamber terminal surface 25 in 3 planet carrier stub side pin shaft holes 24 to compress tightly fixed machine tool workstation 1 with planet carrier 2.
The T-bolt 4 can be adjusted to the appropriate position by moving within the T-slot 11. The tool pressure plate 6 and the T-shaped bolt 4 can be adjusted to proper positions through the strip-shaped holes 61.
The planet carrier 2 needs to calibrate the large end surface 26 on the long head side of the planet carrier 1 before machining, and the planeness of the large end surface 26 on the long head side of the planet carrier is controlled by adjusting 3 jacks 7 so as to achieve the best effect of calibrating the meter.
The existing tooling for finish turning of the long-head side 22 shaft diameter of the planet carrier is to use three equal-height blocks with fixed height to support the short-head side large end surface 23 of the planet carrier. Due to casting and machining errors of parts per se, after one equal-height block contacts the end face, gaps may exist between the upper end faces of the other two equal-height blocks and the large end face 23 on the short head side of the planet carrier, and the proper height is adjusted by heightening the height of the equal-height block on the single side, so that the efficiency is too low.
This frock is directly placed in the jack 7 of planet carrier short-end side 21 through three circumference equipartitions and is supported planet carrier 2 to can reach the clearance adjustment between the head of jack 7 and the big terminal surface 23 of planet carrier short-end side. The efficiency of part clamping is fixed has effectively been promoted like this to reduced the high indisputable height of high-speed railway and mismatch, the cost that needs the preparation frock in addition.
Original fixed mode goes on fixing for compressing tightly the big terminal surface 26 of planet carrier long head side with frock bolt and clamp plate, the work piece is though compressing tightly in the course of working like this, but the work piece processing is accomplished the back, the frock clamp plate that compresses tightly planet carrier 2 loosens the process that has a stress release after loosening, will lead to the precision to descend like this, and this patent is fixed through the inner chamber terminal surface 25 that compresses tightly planet carrier short head side round pin shaft hole 24, this kind of deformation that compresses tightly the mode and produce long head side 22's axle footpath is very little, thereby the machining precision of the axle footpath of assurance planet carrier long head side 22 that can be better.
