The compressor piston plane milling and center hole drilling device can achieve the technical purposes that the structure is simple, production efficiency is high, and manufacturing cost is low.

Description

Compressor piston milling flat and centering device
Technical field
The utility model relates to a kind of device that piston of air-conditioning compressor is carried out to milling flat and drill centers, say more specifically a kind of device that swash-plate air conditioner compressor for automobile piston is carried out to milling flat and drill centers, belong to automobile air conditioner compressor manufacturing technology field.
Background technology
Existing automobile air conditioner compressor adopts oblique tray type compressor mostly, and piston two ends of oblique tray type compressor are cylindrical shape, and centre is swash plate socket, in manufacturing the Piston Process of compressor, first die casting piston blank, for easy to process, is also cast with technique handle at two ends of piston blank.The first operation of compressor piston being carried out to machining is that milling end flat bores two ends centre bore.In the time of can be to piston milling flat for enhancing productivity preferably, can also carry out drill centers work.The structure of the device of existing piston milling flat and drill centers as shown in Figure 1, the base 1 of device has a slide unit 2 in centre position above, piston 3 is contained on slide unit 2, slide unit 2 two sides are furnished with four unit heads 7 altogether, front-seat two is the unit head 7 that carries out Milling Process, for milling piston two transverse planes, two of rear rows are the unit head 7 that carries out Drilling operation, for side face of piston ring drill centers.
Add and first piston 3 is arranged on slide unit 2 man-hour, the milling unit head 7 of first row two sides advances to behind operating position towards piston 3 directions, and slide unit 2 moves forward, and it is good that the cutter blade 4 on unit head is held piston 3 two level with both hands respectively facing cut, and then unit head 7 is return.When slide unit 2 moves on to behind the position of piston drill centers, travel switch sends instruction, slide unit 2 stops, at this moment two side drilling power head 7 F.F.s, the work of second row are entered, centre drill 5 on drilling power head bores respectively piston two ends centre bore, after having bored centre bore, two end centre drills exit backward, and slide unit returns to original position, pulls down workpiece.As can be seen from Figure 1, the milling flat of existing structure and centering device milling flat and drill centers two ends, respectively with a unit head, have been used 4 unit heads altogether.Divide two stations to process, exist apparatus structure complicated, cost is high, and processing beat waits not enough slowly.
Utility model content
The purpose of this utility model is to provide a kind of compressor piston milling flat and centering device, solves and how to make apparatus structure simple, and production efficiency is high, the technical problem that cost is low.
Compressor piston milling flat and a centering device, comprise base, slide unit, the unit head being symmetrically distributed, compound cutterhead, cutter blade, centre drill; Slide unit and unit head are all fixed on base, compound cutterhead is fixed on the rotating shaft of unit head, centre drill is equipped with at this cutterhead intermediate groove place, the center of this centre drill is consistent with the center of unit head rotating shaft, the outer ring of cutterhead is fixed with cutter blade, and the top of this cutter blade exceeds the top 2-4mm of centre drill in the horizontal direction.
The top of described cutter blade exceeds the top 2mm of centre drill.
The beneficial effects of the utility model are: due to cutter blade and centre drill are arranged on same cutterhead, milling flat and drill centers can complete in a station like this, needn't use two unit heads to carry out work, thereby make that whole apparatus structure is simple, operating efficiency is high and cost is low.
Accompanying drawing explanation
Fig. 1 is the schematic diagram of the device of existing piston milling flat and drill centers;
Fig. 2 is the schematic diagram of the device of piston milling flat and drill centers in the specific embodiment;
In figure: 1. base, 2. slide unit, 3. piston, 4. cutter blade, 5. centre drill, 6. compound cutterhead, 7. unit head.
The specific embodiment
Please refer to Fig. 2, compressor piston milling flat and centering device in figure, comprise a base 1, slide unit 2, two unit heads that are symmetrically distributed 7, two compound cutterheads 6, cutter blade 4, centre drill 5; Slide unit 2 and unit head 7 are all fixed on base 1, compound cutterhead 6 is fixed on the rotating shaft of unit head 7, wherein base 1, slide unit 2, unit head 7, cutter blade 4, centre drill 5 are the normal parts that adopt of existing apparatus, and the present embodiment does not too much improve above-mentioned parts, therefore exceed description.
Compressor piston milling flat in the present embodiment and centering device are mainly that former cutterhead is improved, make milling into, bored the compound cutterhead 6 of dual-purpose, on the cutterhead of former installation cutter blade, increase again a centre drill 5, linear velocity when guaranteeing drill centers, when drill centers by the corresponding raising of electrical equipment program setting unit head drive motors rotating speed.The center of above-mentioned centre drill 5 is consistent with the center of the rotating shaft of unit head 7, and cutter blade 4 is installed in the outer ring of compound cutterhead 6, and the top of this cutter blade 4 exceeds the top 2-4mm of centre drill 5 in the horizontal direction, preferably 2mm.
Operation principle and the process of this device are as follows: first piston 3 is fixedly mounted on slide unit 2, two side unit heads 7 advance to behind milling position towards piston 3 direction levels, cutter blade 4 on compound cutterhead 6 just starts the plane at milling piston 3 two ends, when the alignment of shafts of piston 3 centers and two side unit heads 7 is consistent, travel switch sends instruction, slide unit stops, and now two side unit heads 7 enter to piston 3 two ends works respectively, bores two ends centre bore.Two ends centre drill is after set depth, and unit head 7 exits backward, and slide unit returns to original position, pulls down workpiece.Because centre drill 5 tops at compound cutterhead 6 centers are lower than cutter blade 4 top 2mm, so centre drill 5 can not encountered piston 3 end faces when milling flat.Due to the technique shank diameter at piston 3 two ends, be less than again the rotating diameter of the blade on unit head 7, so move to piston center and two ends unit head 7 centers when consistent when slide unit 2, milling is complete for the technique pommel face at piston 3 two ends.
