Description
Technical field
The utility model is related to machining, particularly a kind of crosshead pin and the both ends of the surface with analogous shape part
Processing tool and its processing method.
Background technology
Crosshead pin is the peculiar part of large-sized low-speed diesel engine, is the part for connecting piston component and connecting rod, it has
The effect of guiding, and bear the side-thrust and pulling force of piston, piston reciprocates through it and is transmitted to bent axle.
It is by directly placing one piece of V on lathe table top for the processing of crosshead pin both ends of the surface among prior art
Sections is fixed in the middle of the table top of lathe as frock after correction；Part is placed on v block, reference plane has been proofreaded
After start processing datum, after again by lathe table top rotate 180 ° processing other ends.
The problem of existing process technology is present：Because the lathe table top for processing crosshead pin end face at present is generally larger, and
Total class of current part is various, when processing small size type, and the boring bar of lathe needs to stretch out relatively long distance, can reduce main shaft firm
Property, so as to influence the flatness of processed part；And the running accuracy of big table top lathe is not universal high, also has one to crudy
It is fixing to ring.
Utility model content
The purpose of this utility model is to overcome the defect of above-mentioned existing machining technique, and there is provided a kind of crosshead pin two ends
The processing tool and its processing method in face, disclosure satisfy that the convenient of existing equipment, realize simple reliably complete on existing
Into the processing of crosshead pin, especially the crosshead pin both ends of the surface of small size.Special tooling of the present utility model have it is easy to use,
With low cost, high in machining efficiency, machining accuracy ensures reliable advantage.
The technical solution of the utility model is as follows：
A kind of processing tool of crosshead pin both ends of the surface, including hydraulic swivel, connecting plate, two pieces of v blocks, connecting bolt and
Two block pressur plates；

Described hydraulic pump is used to provide pressure.
Described connecting plate is connected as work top, bottom using alignment pin and bolt with described hydraulic swivel
Connect, top is provided with T-slot, is fixed for described v block.
Described v block and connecting bolt, pressing plate are used cooperatively, and complete the clamping to crosshead pin.
Described hydraulic swivel head is as the base of a whole set of tool component, and it is directly placed on lathe table top, it is necessary to bear
The weight of whole tool component, the frock is used for the crosshead pin (type from 35MEB to 50MEB) for processing small type, so its
Weighted design chooses most heavy 50MEB types, adds the deadweight of frock, and puts 30% safety coefficient, so the liquid of this frock
The design load-bearing of pressure rotating disk should be not less than 2500kg.After hydraulic swivel head rotation specified angle, it is desirable to have alignment pin can be locked
Tightly.Selected hydraulic swivel head meets above-mentioned condition.
Described connecting plate is used as work top, and it is connected with hydraulic swivel head by alignment pin, and is used
Fixing bolt is fixed.Because it is used as work top, it is necessary to have the good depth of parallelism, and load-bearing is needed, mesa designs will
Table top is met in load-bearing 2000kg parallelism errors without departing from 0.02mm.Meanwhile, in order to preferably be pacified on connecting plate
Dress is used, so the design of the connecting plate is designed using the T-slot similar to lathe table top.
Described v block is mounted on connecting plate, utilizes V-type face holding parts；For the facility that part is tuned up, two pieces
The corresponding depth of parallelism will get well between having the inclined-plane of the good depth of parallelism, especially two between v block.While in order to mitigate certainly
Weight, discharges stress, also allows for clamping, v block, which is used, hole design.According to the size of the part of required processing, two v blocks are determined
Spacing；If subsequently requiring machining for smaller like parts, the spacing of two v blocks can also be adjusted.
Depending on size of the design size of connecting bolt and pressing plate according to part, plurality of specifications can be designed, is entered as needed
Row selection.
Hydraulic pump needs to provide enough pressure for fixture system, and the hydraulic pump of selection should be more light and easy to use.
Small volume is also wanted not take up space simultaneously.
Using the processing method of the processing tool of described crosshead pin both ends of the surface, this method comprises the following steps：
1. hydraulic swivel head is arranged on lathe table top close to main shaft side, is stretched out and grown according to the size of lathe table top and boring bar
Degree determines precise mounting position, and hydraulic swivel head is locked on lathe table top using alignment pin, and by hydraulic swivel head and hydraulic pump
Connection；
2. connecting plate is arranged on hydraulic swivel head by alignment pin and bolt, and ensures that its flatness tolerance does not surpass
0.02mm；
3. two pieces of v blocks are arranged on connecting plate, coordinated using the T-slot of T-nut, stud and connecting plate,
It is fixed, it is ensured that the parallelism tolerance of two v blocks is no more than 0.01mm；
4. crosshead pin is centrally placed on two pieces of v blocks, reference plane corrects transverse plane just to boring bar, by even
Connecting bolt and pressing plate make after crosshead pin fixation, start processing datum；
5. after reference plane is machined, the alignment pin on hydraulic swivel head is unclamped, the use of hydraulic pump is hydraulic swivel head voltage supply, makes
It floats and rotated after 180 °, using positioning pin locked, post-processing crosshead pin other end, after the completion of complete whole
The processing of process.
Compared with prior art, the beneficial effects of the utility model are as follows：
1) installed when using on machine-tool platform face close to machine tool chief axis side, overcome accessory size and lathe table top not phase
The shortcoming of matching；
2) because there is frock itself good precision, once mounting just can be used for a long time after regulating, no
The workload of the tune-up of part can additionally be increased.
3) the characteristics of having simple in construction, v block spacing can also be adjusted as the case may be by having during demand.
4) easy to use, the characteristics of stable accuracy is reliable, satisfaction to middle-size and small-size crosshead pin and has on existing lathe
The convenient processing of similar structures part both ends of the surface.
