Description
Technical Field
The utility model belongs to the technical field of wind-powered electricity generation gear box processing frock and specifically relates to a frock of reprocessing usefulness after LSS planet carrier and main shaft assembly.
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;
before the main shaft and the LSS planet carrier are assembled, all finish machining processes of the main shaft are finished, but a pin shaft hole of the LSS planet carrier is not subjected to finish boring in place; and the pin shaft hole of the LSS planet carrier can be finely bored after the pin shaft hole is assembled with the main shaft which is finished by finish machining.
The main reasons for the process schedule are: due to the general interference fit of the matching between the LSS planet carrier and the main shaft, the planet carrier and the main shaft can be assembled only after the planet carrier needs to be placed in an oven for high-temperature isothermal treatment, and in order to prevent the pin shaft hole from deforming after the LSS planet carrier and the main shaft are assembled at high temperature, the fine boring process of the pin shaft hole of the LSS planet carrier must be arranged after the LSS planet carrier and the main shaft are rotationally matched, so that the form and position tolerance of the pin shaft hole of the LSS planet carrier is ensured.
At present, when a combination is machined, the large outer circle of the planet carrier and the outer circle of the main shaft are clamped by a V-shaped iron with a fixed height, and the pin shaft hole of the LSS planet carrier is finely bored after clamping and positioning.
One scheme is as follows: the height of the V-shaped iron is calculated in advance through the size of the excircle of the main shaft flange provided by designers, the main shaft flange is fixed through the V-shaped iron with fixed height, and the large excircle of the LSS planet carrier is fixed through the jack.
The disadvantages of this solution are:
1. the height of the V-shaped iron is fixed, and the V-shaped iron with the fixed height is not strong in universality due to the fact that the size of the large excircle of the LSS planet carrier is different from the size of the excircle of the main shaft flange aiming at different types of combined bodies;
2. the processing of the combination bodies of different machine types needs to manufacture V-shaped irons with different heights in advance, so that the processing cost is higher;
3. the height of one side is adjusted by a jack, the contact area is too small, the clamping is not stable enough, the processing process is careless, the workpiece is easy to displace, and the processing precision of the part is influenced;
4. when the V-shaped iron with the fixed height is clamped, the efficiency of parts is low when the parts are clamped and corrected on a machine tool, and the adjustment is time-consuming.
The other scheme is as follows: through the LSS planet carrier big excircle size that the designer provided and the size of main shaft flange excircle, calculate the height of V-arrangement iron in advance, the main shaft flange is fixed through the V-arrangement iron of fixed height, and the big excircle of LSS planet carrier is fixed through the V-arrangement iron of fixed height equally.
The disadvantages of this solution are:
1. the height of the V-shaped iron is fixed, and the universality of the V-shaped iron with the fixed height is not strong due to the fact that the size of the large excircle of the LSS planet carrier is different from the size of the excircle of the main shaft flange aiming at different types of combined bodies;
2. both sides all use the V-arrangement iron of fixed height to carry out the clamping location, because the part of self exists casting and machining error, after one side and V-arrangement iron are fixed, probably there is the clearance between another one side excircle and the V-arrangement iron, need adjust suitable height through raising unilateral V-arrangement iron at this moment, and efficiency is too low.
SUMMERY OF THE UTILITY MODEL
The utility model provides a but processing height-adjusting's processing frock is used in LSS planet carrier and main shaft assembly back processing, but its purpose is solved the shortcoming of prior art, promotes the fixed efficiency of part clamping to reduce the cost of preparation frock.
The utility model provides a technical scheme that its technical problem adopted is:
but LSS planet carrier and main shaft assembly post-processing use height-adjusting's processing frock, and the main shaft assembles with the LSS planet carrier, and the main shaft supports on V shaped iron, its characterized in that:
the base support is placed on a workbench of a machine tool, the lower surface with the slope of the upper plate is lapped on the upper surface with the slope of the lower plate and is in inclined plane fit, and the slope of the lower surface of the upper plate is the same as that of the upper surface of the lower plate;
the upper surface of the upper plate is fixedly provided with a V-shaped iron, and the LSS planet carrier is supported on the V-shaped iron;
two guide plates are respectively arranged on the two side surfaces of the upper plate and the lower plate and fixed on the base support;
the stud support is fixed on the base support, the stud penetrates through the transverse through hole of the stud support and then is screwed into the threaded hole in the side face of the lower plate, and the stud is limited on the stud support left and right;
two limiting pins extend out of two sides of the upper plate respectively;
the two limiting pins on the same side are positioned on the opposite inner sides of the two guide plates on the same side, or the two limiting pins on the same side are positioned on the opposite outer sides of the two guide plates on the same side;
and the two limit pins are respectively propped against the two guide plates.
The head of the stud is provided with a hexagonal head.
The structure that the double-screw bolt is spacing about on the double-screw bolt supports does: the pin supported and extended by the stud is inserted into the ring groove arranged on the stud.
The structure that the double-screw bolt is spacing about on the double-screw bolt supports does: the stud is welded on two sides of the stud support to form a limiting block which abuts against the side face of the stud support.
The utility model discloses an useful part lies in:
the structure is simple, and the processing and the manufacturing are easy; the universality is stronger, and the tooling cost is saved; the operation can be carried out by a single person, so that the labor cost is reduced; the height of the V-shaped iron is adjusted at any time, so that the V-shaped iron is clamped and fixed at the most appropriate position, the fixation is firmer, and the processing stability is improved. The existing tool is clamped and positioned by using V-shaped iron with fixed height on two sides, and due to casting and machining errors of parts per se, after one side of the tool is fixed with the V-shaped iron, a gap may exist between the excircle on the other side of the tool and the V-shaped iron, and at the moment, the proper height is adjusted by raising the V-shaped iron on one side, so that the efficiency is too low. This frock moves the hypoplastron removal that the double-screw bolt drove and has the grade of a definite slope through the board to drive the V-arrangement iron on the upper plate and remove from top to bottom, can reach the altitude mixture control of V-arrangement iron, effectively promoted the fixed efficiency of part clamping like this, and reduced because of the V-arrangement iron highly mismatch, need make the cost of frock in addition.
