Abstract
The invention discloses a fixture for milling a tile slot and a thrust surface of an engine cylinder body. The fixture comprises a base which is provided with a front supporting block and a back supporting block; two supporting rods are arranged on the outer side of the front supporting block, and two supporting rods are arranged in the corresponding positions of the outer side of the back supporting block; pressing blocks are movably installed at the upper ends of the supporting rods on the inner sides, and locking nuts for locking the pressing blocks are installed at the upper ends of the supporting rods on the inner sides in a screwing matching mode; a longitudinal baffle matched with the back side surface of the engine cylinder body is installed in the position, between the front supporting block and the supporting rods on the inner sides, of the base, and the upper end of the longitudinal baffle is provided with a limiting plate matched with the bottom surface of the engine cylinder body; and the middle of the limiting plate is provided with a guiding slide groove matched with one of the pressing blocks, and positioning pins matched with positioning pin holes in the bottom surface of the engine cylinder body are arranged in the positions, on the two sides of the guiding slide groove, of the limiting plate. According to the fixture for milling the tile slot and the thrust surface of the engine cylinder body, the supporting blocks, the supporting rods, the pressing blocks, the positioning pins and other assemblies which are arranged on the base are used in a matched mode so that the top surface and the bottom surface of the cylinder body can be quickly clamped; and after clamping, the stability of the cylinder body is good, and milling machining of the tile slot and the thrust surface is convenient to conduct.
Description
Technical field:
The present invention relates to engine cylinder-body processing, particularly relate to a kind of engine cylinder-body milling watt groove thrust surface fixture.
Background technology:
Electromotor is made up of cylinder block and cylinder cover two large divisions, is inter-connected via a bolt joint.Cylinder block material should have enough intensity, good opourability and machinability, and price is low, and therefore conventional cylinder block material is cast iron, alloy cast iron.But the cylinder body of aluminium alloy uses more and more universal, because aluminium alloy cylinder is lightweight, heat conductivity is good, and the capacity of coolant can reduce.After startup, cylinder body quickly reaches operating temperature, and just the same with aluminium recovery thermal coefficient of expansion, and the post gap that is heated change is little, can reduce impact noise and consumption of lubricating oil.And identical with aluminum alloy cylinder cover thermal expansion, work can reduce thermal stress produced by thermal shock.
Its planform of engine cylinder-body is relatively complicated, before watt groove in cylinder body and the processing of thrust surface, needs to carry out clamping, and clamping fastness and stability directly result in the crudy of watt groove.
Summary of the invention:
In order to make up prior art problem, it is an object of the invention to provide a kind of engine cylinder-body milling watt groove thrust surface fixture, novel in structural design, can quickly cylinder body bottom surface and end face be clamped, clamping rear-bank rotor housing good stability, the Milling Machining operation of convenient watt groove and thrust surface.
Technical scheme is as follows:
Engine cylinder-body milling watt groove thrust surface fixture, including pedestal, pedestal upper surface is parallel and is arranged at intervals with and supports forward support block, the aft support block that engine cylinder-body end face matches, outside forward support block, aft support block, opposite position is equipped with two support bars, medial branch strut upper end is movably installed with compact heap, medial branch strut upper end screws the locking nut being provided with locking compact heap, and the afterbody of compact heap rides on lateral branch strut；
The longitudinal baffle matched with engine cylinder-body trailing flank is installed on the pedestal between forward support block with medial branch strut, longitudinal baffle upper end is provided with the limiting plate matched with engine cylinder-body bottom surface, offer the guide chute matched with compact heap in the middle part of limiting plate, the limiting plate of guide chute both sides is equipped with the alignment pin matched with engine cylinder-body bottom surface dowel hole.
Described engine cylinder-body milling watt groove thrust surface fixture, it is characterised in that described compact heap is taper block, wherein compressing end is head width, and afterbody rides on the support bar in outside, offers and the kidney-shaped adjustment hole movable for interior survey support bar in the middle part of compact heap.
The invention have the advantage that
Present configuration is novel in design, by the bracer on pedestal, support bar, compact heap, the inferior assembly in location with the use of, quickly cylinder body bottom surface and end face can be clamped, clamping rear-bank rotor housing good stability, the Milling Machining operation of convenient watt groove and thrust surface, improve machining accuracy, reduce hand labor intensity.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the use state diagram of the present invention.
Detailed description of the invention:
See accompanying drawing:
Engine cylinder-body milling watt groove thrust surface fixture, including pedestal 1, pedestal 1 upper surface is parallel and is arranged at intervals with and supports forward support block 2, the aft support block 3 that engine cylinder-body end face matches, outside forward support block 2, aft support block 3, opposite position is equipped with two support bars 4,5, medial branch strut 4 upper end is movably installed with compact heap 12, medial branch strut 4 upper end screws the locking nut 6 being provided with locking compact heap, and the afterbody of compact heap 12 rides on lateral branch strut 5；
The longitudinal baffle 7 matched with engine cylinder-body trailing flank is installed on the pedestal between forward support block 2 with medial branch strut, longitudinal baffle 7 upper end is provided with the limiting plate 8 matched with engine cylinder-body bottom surface, offer the guide chute 9 matched with compact heap 12 in the middle part of limiting plate 8, the limiting plate of guide chute 9 both sides is equipped with the alignment pin 10 matched with engine cylinder-body bottom surface dowel hole.
Compact heap 12 is taper block, and wherein compressing end is head width, and afterbody rides on lateral branch strut 6, offers and the kidney-shaped adjustment hole 11 movable for interior survey support bar in the middle part of compact heap 12.
Engine cylinder-body is sling by electric block and is transported to correct position by the present invention, engine cylinder-body end face positions with forward support block 2, aft support block 3, engine cylinder-body trailing flank longitudinal baffle 7 matches, and matched with engine cylinder-body bottom surface dowel hole location by alignment pin, lock finally by compact heap 12 and locking nut 6, finally carry out Milling Machining operation.
