Refer to Fig. 5, described pressing plate 3 comprises pressing plate seat 31, pressing plate head 32 and Compress Spring 33; Described pressing plate seat 31 is fixedly installed in the upper plane of described fixed head 5, described pressing plate head 32 is inserted in the centre bore of described pressing plate seat 31, and this pressing plate head 32 can rotate in the centre bore of pressing plate seat 31, described Compress Spring 33 is arranged in this centre bore and between described pressing plate seat 31 and pressing plate head 32, described pressing plate head 32 is connected on pressing plate seat 31 through this Compress Spring 33 by a bolt 34.
Described hydraulic selector 4 is arranged at the bottom of described base body 1, is connected with described hydraulic claw 2, and this hydraulic selector 4 can drive described hydraulic claw 2 to carry out moving to clamp described cooling injection plate A along the radial direction of described fixed head 5.
Because of the design feature in hole on cooling injection plate A, bolt hole A4 and pin-and-hole A6 cannot machine on same station, need part to stand up clamping once, so need the two cover various combinations adopting described frock on two stations, and stand up rear part and strictly need control repetitive positioning accuracy.
First station frock main parts size see Fig. 9, comprise base body 1, hydraulic claw 2, pressing plate 3, hydraulic selector 4, for the cooling injection plate A of different type of machines and the removable fixed head 5 customized and back-up block 8.Its installation method is as follows:
1, described frock guarantees that each part is intact bad before installing, and guarantees that each threaded connector screw thread is without rotten tooth, base welding region flawless.
2, the workbench of clean upright type five-shaft machining center, ensures without iron filings.
3, lift by crane described frock by hanger, ensure level, slowly keep flat and be placed on workbench.
4, base body 1 (together with the hydraulic cylinder on it, hydraulic selector 4 and hydraulic claw 2) with the center positioning hole on workbench for benchmark, by alignment pin 6, rely on side locating piece 7 by tool locating and keep flat and be mounted on workbench, then by uniform 4 bolt and nuts, base body 1 is compressed on the table.
5, select corresponding fixed head 5 according to cooling injection plate A to be processed, installation pressing plate 3 and back-up block 8 are on the relevant position of fixed head 5.
6, process front probe to measure on the isometry position of hydraulic claw 2, namely height error is considered as frock installation within 0.02mm.
The utility model is installed according to above-mentioned installation method when first time uses, and the part of different model also only needs to change fixed head 5, and without the need to pulling down base body 1, hydraulic claw 2 only uses when part location and installation.After process finishing, as next part processing need be carried out, as long as allow hydraulic claw 2 pressure release, unclamp pressing plate 3, without the need to again adjusting hydraulic claw 2 position, greatly reduce like this frock repeatedly get on or off the bus and part multiple operation get on the bus school adjust time.
Second station frock as shown in Figure 10, comprise base body 1, pressing plate 3, back-up block 8, for the cooling injection plate A of different type of machines and the removable fixed head 5 customized and locating piece 9.Second station part pin-and-hole A6 locates, and without the need to hydraulic claw 2, therefore eliminates hydraulic test.
Second station frock installation method, with reference to the first station installation method, finally also needs, with probe calibration platen support place isometry position, to determine that height error is within 0.02mm.
Described frock is installed according to above-mentioned installation method, because the cooling injection plate A shape of the Wa Xilan diesel engine of different cylinder diameter is similar, only size has size to distinguish, so only need the fixed head 5 of replacing first station during cooling injection plate A clamping, and change pressing plate 3 position; Second station frock change locating piece 9 position, pressing plate 3 position, all without the need to pulling down base body 1.Hydraulic claw 2 only uses when part location and installation.After process finishing, as next part processing need be carried out, as long as allow hydraulic claw 2 pressure release, unclamp pressing plate 3, without the need to again adjusting hydraulic claw 2 position.Greatly reduce during such processing different bore diesel engine jet tray different frock repeatedly get on or off the bus and part multiple operation get on the bus school adjust time.The utility model is applicable to part in enormous quantities and produces, and if lathe is single workbench, unifies processing first station man-hour adding, changes the second station frock and process after the first station all machines.
Adopt the concrete operation of the utility model processing cooling injection plate A as follows:
First station:
Preparation: by clean for part clean, guarantee datum plane impulse-free robustness flange, whether initial workpiece is reviewed last process size and processed according to process.
Operation 1: part lies on the supporting plane of hydraulic claw 2 and back-up block 8, sees Fig. 6, with hydraulic pressure draw-bar or numerical control program adjustment jaw position, makes claw automatically clamp part outer (self-centering).
Operation 2: the pressing plate 3 of compression tooling surrounding is in part end face, and pressing plate 3 compacted position is close to 1/4 semicircle place in frock, sees Fig. 7, attentional manipulation thrust, to prevent from unclamping the rear part deformation of pressing plate 3, shutoff operation door.After clamping as shown in Figure 9.
Operation 3: run full-automatic numerical control program, the main processing content of the first station is as follows:
1) bore by figure, expand, cut with scissors 18 the first inclined hole A1.
2) bore, expand, cut with scissors 12 the second inclined hole A2.
3) bore, expand, cut with scissors 6 the 3rd inclined hole A3.
4) bore, expand, cut with scissors 2 pin-and-hole A6 and pin-and-hole mouth carries out chamfering 2 × 45 °.
Operation 4: unclamp pressing plate 3, see Fig. 8, part stands up.
Second station:
Preparation is as the first station.
Operation 1: part stands up and lies in described frock, positions with locating piece 9 in pin-and-hole A6 on part and frock.
Operation 2: compression tooling surrounding pressing plate 3 is in part end face, and pressing plate 3 compacted position is close to 1/4 semicircle place in frock, sees Fig. 7, attentional manipulation thrust, to prevent from unclamping part deformation after pressing plate, shutoff operation door.After clamping as shown in Figure 10.
Operation 3: run full-automatic numerical control program, the main processing content of the second station:
1) bore 9, hole through hole A5.
2) bore, expand 3, hole bolt hole A4.
3) bottom outlet to bolt hole A4 is bored.
4) screw thread to bolt hole A4 is attacked.
Operation 4: process finishing, unclamp pressing plate 3, see Fig. 8, part is got off.
Be more than a best embodiment of the present utility model, protection domain of the present utility model can not be limited with this.What protection domain of the present utility model also comprised other is apparent conversion for those skilled in the art and substitutes.
