Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described in further detail.
As shown in Figures 1 to 6, this manual pallet truck oil pump case hole machined tool mechanism comprises:
Numerical control scale-division dish 2 is the executing agency of this tool mechanism, can rotate, calibration and location under the effect of the heart in the controlling.Numerical control scale-division dish positioning key 91 is connected with workbench 9 centering at machine tooling center, and by pressing plate 92 and follower bolt 93 fixing on the table, prevent from adding man-hour numerical control scale-division dish and rotate voluntarily; Oil pipe 25 on numerical control scale-division dish is communicated with external hydraulic station (not shown), and the control line 26 of numerical control scale-division dish is by holding wire (not shown) and amplifier (not shown) connecting machine tool control system (not shown).
Ring flange 1, is arranged on the chuck 22 of numerical control scale-division dish 2, plays the effect of pedestal.In the present embodiment, the connected mode of ring flange 1 and chuck 22 is: on ring flange 1 and chuck 22, be respectively equipped with corresponding centre bore 15,21, and mandrel 3 is plugged in two corresponding centre bores; The both sides of centre bore are also provided with two locating holes, and setting circle pin 7 is plugged in corresponding locating hole; Surrounding multiple T-nut 8 and the screw lock of mandrel.By said method, firm for ring flange is arranged on chuck 22, and connects accurately, firmly.Thus ensure that the centre of gyration of ring flange, oil pump case to be processed is consistent with the centre of gyration of described numerical control scale-division dish.
Manufactured flat surface part ring flange 1 corresponding to oil pump case 6 to be processed is also provided with the first bolt 21 and the second bolt 27.Ring flange can also arrange according to the manufactured cylinder holes of oil pump case to be processed the position connecting bearing pin.Oil pump case to be processed in the present embodiment has processed large cylinder holes and little cylinder holes before carrying out shoulder hole processing, therefore ring flange 1 corresponds on these two cylinder holes positions and is also provided with two pin-and-holes, by large cylinder holes locating shaft 23 and little cylinder holes locating shaft 24 oil pump case to be processed is spacing further.In order to enable oil pump case to be processed be assembled to smoothly on ring flange, avoid because the pitch-row mismachining tolerance between large cylinder holes and little cylinder holes causes clamping inconvenient, the little cylinder holes locating shaft in the present embodiment adopts cuts flat design.
When installing to make this tool mechanism and oil pump case to be processed, the debugging of angle zero-bit is convenient, the present embodiment also processes a long plane at ring flange circumference, the installing hole of this long plane and large cylinder holes locating shaft, little cylinder holes locating shaft processes simultaneously, during installation, even up this plane with dial gauge and get final product zero set.
Clamping plate 5, for clamping and locating oil pump case 6 to be processed.An ora terminalis of the clamping plate 5 in the present embodiment is interval with the first breach 51 and the second breach 52 and a screw.Clamping plate through attaching nut 4 after screw, thus are rotatably connected on ring flange 1 by the first bolt 21.Second bolt 27 is corresponding with the position of the first breach 51, and it is also connected with nut 4, and the first breach 51 and screw are symmetrical centered by the second breach 52.
Above-mentioned numerical control scale-division dish is by holding wire and amplifier connecting machine tool control system (not shown).
Before oil pump case to be processed is installed, first screw out clamping plate, then horizontal positioned oil pump case to be processed, oil pump case to be processed is inserted in little cylinder holes locating shaft and large cylinder holes locating shaft respectively, after oil pump case to be processed large cylinder holes medial plane and large cylinder holes locating shaft step surface are fitted, rotate clamping plate, make the second bolt and mandrel snap in the first breach and the second breach respectively, tighten the nut on the first bolt and the second bolt, accurately can locate and steadily lock oil pump case to be processed.
Numerical control scale-division dish is connected with vertical machining center by holding wire, amplifier, by any anglec of rotation that can set around X-axis of programming, thus drive ring flange to rotate together with oil pump case to be processed, complete the processing in hole, oil pump case Different Plane place.
