The refined grinding device and grinding tool of the large copper sleeve inner hole on the common engine lathe are specially transformed on the common engine lathe so that refined grinding can be carried out on the copper sleeve inner hole. The refined grinding device and the grinding tool have simple structure, are convenient to use, save machining cost and are suitable for large-batch production.
Description
Technical field
The utility model belongs to the lathe servicing unit of machining, and particularly a kind of big copper sheathing endoporus finish grindes processing unit (plant) and grinding tool on engine lathe.The device of a kind of special special use of processing of correct grinding copper sheathing endoporus and a kind of on engine lathe at the special process of copper product inner hole grinding and special grinding tool.
Background technology
In endoporus fine finishining grinding, generally all adopt special-purpose endoporus grinding machine, because the workpiece profile is bigger, generally there is not big like this grinding machine, make grinding to finish.Moreover, because endoporus is a copper material, hardness has only HB40-60, shows as stickingly, and the working surface roughness is difficult to reduce, workpiece has ground the surface and has been scratched easily, this is because copper has low-melting characteristic, in grinding process, under the effect of grinding heat, abrasive dust adheres to easily and causes emery wheel to stop up on the emery wheel, and grinding efficiency is also extremely low.
The utility model content
The purpose of this utility model provides a kind of big copper sheathing endoporus and finish grind processing unit (plant) and grinding tool on engine lathe, be to utilize the in addition transformation of part of engine lathe, on the position of former tool post, installed special-purpose grinding head device additional, utilize the counter-rotating and the axially feed of lathe itself of main shaft (workpiece) and bistrique, use special emery cloth page or leaf sheet wheel, under the situation that does not have big endoporus grinding machine, the use engine lathe has just been finished the fine finishining to the copper sheathing endoporus, the efficient height, the quality perfection.
Content of the present utility model is:
A kind of big copper sheathing endoporus finish grindes processing unit (plant) and grinding tool on engine lathe, it is characterized in that: in the knife rest on engine lathe on the supporting plate with five screw fixed connecting plates, the bearing of bistrique in being equipped with on the connecting plate, bistrique and motor are housed on the bearing, and the belt pulley of bistrique links to each other with the belt pulley of motor by belt.
Grinding wheel on the bistrique is the Emery cloth impellers that has certain angle.
The utility model has the advantages that:
This big copper sheathing endoporus finish grindes processing unit (plant) and grinding tool on engine lathe, be to utilize the special repacking of process on the engine lathe, can finish grind processing to the copper sheathing endoporus on engine lathe, simple in structure, easy to use, save processing cost, be suitable for producing in enormous quantities.

，
The specific embodiment
A kind of big copper sheathing 11 endoporus shown in Fig. 2,3 finish grind processing unit (plant) and grinding tool on engine lathe, on the middle supporting plate 3 of the knife rest on the engine lathe with five screws, 2 fixed connecting plates 1, the bearing 4 of bistrique in being equipped with on the connecting plate, bistrique and motor 8 are housed on the bearing, and the belt pulley 6 of bistrique links to each other with the belt pulley 8 of motor by belt 7.Middle supporting plate 3 and feed wheel 9 interlocks.
Grinding wheel on the bistrique is the Emery cloth impellers 10 that has certain angle.
A kind of special repacking of process on engine lathe, can on engine lathe, finish grind processing to copper sheathing 11 endoporus, it is characterized in that on engine lathe, knife rest partly being dismantled, load onto connecting plate, be fixed on the middle supporting plate with five screws in the place of former knife rest.The bearing of bistrique in being equipped with on connecting plate is equipped with special-purpose grinding head body on the bearing, the belt pulley of bistrique links to each other with the belt pulley of motor by belt.
The grinding bistrique is characterised in that, used the abrasive cloth flapwheel that has certain angle to carry out grinding as grinding tool.
Process two crucial copper sheathings, the outside is a cast iron, in stud with material and be: the copper sheathing of ZQSn6-6-3.As shown in Figure 1.The processing difficulties of this part is
1, internal-external circle concentricity is had relatively high expectations.
2, especially the requirement of endoporus precision and roughness is all very high, is difficult to reach.
3, processing is restricted, and so not big interior circle grinds endoporus, adopts machined into precision and roughness all can not guarantee.
Afterwards, we had adopted on the CW61100 engine lathe through tackling key problem, and the way that time processing survives has guaranteed the high-quality of part processing.
Behind the copper sheathing, we have adopted following process in part has press-fited
One, adopt traditional processing method, earlier the processing of part cylindrical is survived, endoporus stays the mill amount
Two, then the knife rest of lathe is partly dismantled, change the interior grinding head device of repacking, as shown in Figure 2
Three, dividing slightly, finish grind secondary grinding endoporus survives
On lathe knife rest is partly dismantled, load onto connecting plate 1. in the place of former knife rest, 3. supporting plate is gone up in 2. being fixed on five screws.5. 4. the bearing of bistrique be equipped with special-purpose grinding head body in being equipped with on connecting plate on the bearing, and 8. 7. 6. the belt pulley of bistrique link to each other with the belt pulley of motor by belt.Start machine tool chief axis, make main shaft (workpiece) rotation, start grinding head motor and make turning to and the workpiece switched in opposite of bistrique, utilize the axial feed of lathe just can finish the grinding of endoporus.
But copper product hardness is low, and ductility is big, mainly shows as stickingly, and low-melting characteristic makes that in grinding process copper scale is easy to adhere to emery wheel under the effect of grinding heat, causes emery wheel to stop up, and grinding efficiency is extremely low.The surface of grinding is easy to scratch, and the workpiece surface roughness value is difficult to be minimized, and material coefficient of thermal expansion coefficient height, workpiece easy deformation, machining accuracy are difficult for grasping.
We have adopted abrasive cloth flapwheel that emery cloth a slice a slice is bonded together to carry out grinding.And emery wheel page or leaf sheet sticked into axis become certain angle, the generation of heat when having reduced grinding so more helps carrying out smoothly of grinding.Rotate 9. (see figure 2) of middle carriage leading screw handwheel during upper slitter, make abrasive cloth flapwheel contact, and give certain pressure with workpiece.Owing to be that a slice a slice emery cloth layer sticks into, when every layer of emery cloth rotation breaks away from workpiece, be squeezed and release suddenly by original emery cloth sheet, taken away the heat that many grindings produce, also shrugged off the copper scale that cuts simultaneously, make grinding become very brisk.
The selection of emery cloth granularity: corase grind: 80# correct grinding: 100#
The selection of grinding dosage: 2300 rev/mins of speeds of grinding wheel
Corase grind: workpiece rotational frequency 20rpm grinding depth 0.05mm
Axial feeding 3mm/r
Correct grinding: workpiece rotational frequency 16rpm grinding depth 0.01mm
Axial feeding 1mm/r
Facts have proved: No. one time the clamping axiality is guaranteed
The endoporus roughness reaches after testing
Meet the drawing requirement fully.
