The utility model discloses an adjustable external grinding device, including be used for with top axle and two the at least adjusting plates of being connected of grinding machine two, the adjusting plate is equipped with central through -hole, at least one axle fastening through -hole and a plurality of part fastening through -hole, the axle is worn to locate in the central through -hole, be equipped with the annular groove around central through -hole on the adjusting plate, the inside wall and the central through -hole of axle fastening through -hole intercommunication annular groove, the lateral wall and the outer periphery of adjusting plate of part fastening through -hole intercommunication annular groove, be equipped with a fastening screw in the axle fastening through -hole, be equipped with part fastening screw in the part fastening through -hole. This device is suitable for the work piece of different length, simple structure, and the simple operation need not to inlay more the large size vexed head or joins in marriage and do the mandrel, reduce cost.
Description
Technical field
This utility model is related to a kind of scalable cylindrical grinding device, especially for coal-winning machine tubular class part cylindrical grinding
Device, belongs to machining tool clamp technical field.
Background technology
In cylindrical grinding process, common installation way is on the top centre bore withstanding on part in two.Tube shape component
Body can not possibly retain centre bore, and common processing technique, by the way of inlaying silently or doing cooperation heart axle, meets cylindricalo grinding
Installation way.
When tube shape component size is larger or endoporus does not have higher required precision, using the economy of above two mode
Just very poor with manufacturability.It is mainly manifested in：Edge large-size silently, increases subsidiary materials cost, and silently can not be secondary
Use；Part inner hole precision itself requires low, for doing cooperation heart axle, inner bore of part polish, increase manufacturing cost.
Utility model content
This utility model provides a kind of scalable cylindrical grinding device, realizes clamping during tube shape component cylindrical grinding, and real
Now reuse.
Technical solutions of the utility model are as follows：A kind of scalable cylindrical grinding device, including for connection top with grinding machine two
Axle and at least two adjustment plates, described adjustment plate is provided with center through hole, at least one axle fastening through-hole and some fastening parts
Through hole, described axle is arranged in described center through hole, and described adjustment plate is provided with annular groove around described center through hole, described
Axle fastening through-hole connects the medial wall of described annular groove and described center through hole, and described fastening parts through hole connects described annular
The lateral wall of groove and described adjustment plate outer circumference surface, are provided with axle trip bolt, described fastening parts in described axle fastening through-hole
It is provided with fastening parts screw in through hole.
Further, described axle is provided with vertically some location holes, described axle trip bolt passes through axle fastening through-hole and twists
Enter described location hole.
Preferably, described fastening parts through hole is provided with eight.
Preferably, described fastening parts through hole is equidistantly spaced from along the annular of annular groove.
The advantage of technical scheme provided by the utility model is：By the change of adjustment plate axial location on axle,
It is suitable for the workpiece of different length；Adjusted by the screwing length of holding screw, be suitable for the workpiece of different inner diameters within the specific limits.
This apparatus structure is simple, simple operation, can save large-size silently or heart axle is hence it is evident that improve utilization ratio of device, reduce life
Produce cost.
Brief description
Fig. 1 is this utility model structural representation.
Fig. 2 is adjustment plate structural representation.
Specific embodiment
With reference to embodiment, the utility model is described in further detail, but not as to restriction of the present utility model.
As shown in Figures 1 and 2, the scalable cylindrical grinding device involved by the present embodiment, including for top with grinding machine two
The axle 1 connecting and two adjustment plates 2.Axle 1 adopts quenched material, is made using techniques such as car, mill, grindings.During adjustment plate 2 is provided with
Centre 3, axle fastening through-hole 4 of through hole and eight fastening parts through holes 5.Adjustment plate 2 is provided with annular around center through hole 3 recessed
Groove 6, axle fastening through-hole 4 connects medial wall 61 and the center through hole 3 of annular groove 6, and eight fastening parts through holes 5 are along annular groove
6 annular is equidistantly spaced from, and connects lateral wall 62 and the adjustment plate outer circumference surface 21 of annular groove 6, is provided with axle fastening through-hole 4
Axle trip bolt 7, is provided with fastening parts screw 8 in fastening parts through hole 5.Some location holes are provided with axle 1, axle 1 is worn vertically
In center through hole 3, axle trip bolt 7 is screwed into location hole by axle fastening through-hole 4.This device passes through adjustment plate 2 and axle 1 phase
Change to position, is adjusted being relatively fixed it is achieved that adapting to different length of disk 2 and axle 1 using the location hole of diverse location
Degree workpiece clamp and cylindrical grinding work.
When specifically carrying out clamping regulation, adjustment plate 2 is arranged on inner hole of workpiece both sides, pretension fastening parts screw 8, incites somebody to action
Adjustment plate 2 is connected with workpiece；Axle 1 is passed through the center through hole 3 of two adjustment plates 8, by two axle trip bolts 7 fixing axle 1
With adjustment plate 2；By lathe in integral hoisting (or waving instrument), two top withstand axle 1, in the collateral dial gauge of excircle of workpiece two, adjust
Bearing trip bolt 7 it is ensured that excircle of workpiece is coaxial with axle 1, fastenings trip bolt 8 again；Start grinding work piece cylindrical.
