Description
Technical field
The utility model relates to electric magnetic no-core clamp, the Novel electromagnetic centreless clamp that especially a kind of vertical grinder uses, and belongs to mechanical equipment technical field.
Background technology
Vertical numerical control grinding machine is recent year development multi-functional compound grinding machine faster, is widely used in the clamped one time multi-surface composite grinding processing such as the surfaces externally and internally of the industry parts such as large size bearing, gear, water pump and end face.Present stage, the installation way of vertical grinder workpiece had two kinds: the first adopts the installation way of three-jaw or four paws floral disc; The second adopts magnechuck, relies on magnetic force to hold the mode of workpiece end face.
The shortcoming of prior art: when the first adopts the installation way of three-jaw or four paws floral disc, Workpiece clamping power is large.Be easier to cause distortion when processing parts wall is thin, affect machining accuracy; The part of loading, unloading simultaneously comparatively bothers, and affects efficiency.The second adopts magnechuck, relies on magnetic force to hold the mode of workpiece end face, and relative first method distortion is little.But when part wall is thin, because suction is directly proportional to contact area, because contact area diminishes, in order to ensure that suction need strengthen magnetic force, after causing grinding, residual force is out of shape.Not taking simultaneously cylindrical as positioning datum because adding man-hour, the axiality requirement of the inside and outside circle of processing parts cannot be ensured.Do not have positioning datum when installing workpiece simultaneously, repeatedly must repeatedly come centering workpiece center consistent with work table rotation center by rotary table, adjustment comparatively bothers.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, provides the electric magnetic no-core clamp that a kind of vertical grinder uses, and this fixture had both solved clamping quick position, does not need artificial centering; Employing excircle orientation supports, and solves again because magnetic force greatly easily causes a distortion difficult problem; Simultaneously because doing the axiality requirement of inside and outside circle of supporting position assurance with cylindrical.
According to the technical scheme that the utility model provides, the electric magnetic no-core clamp that a kind of vertical grinder uses comprises lathe bed, rotary table; Be provided with rotary table in described lathe bed, magnechuck is arranged on rotary table, turns round around the sucker alignment of shafts with rotary table; Feature is: also comprise workpiece end face supporting, clamp base, retainer ring, rear support seat, rear supports, left support body and left support seat; Described workpiece end face supporting is arranged on magnechuck, and workpiece lower surface is bearing in workpiece end face supporting and above also can slides on end surface supporting; Be provided with clamp base in the workbench outer of lathe bed, Plane Installation fixture retainer ring in clamp base, retainer ring is provided with two T-slot, and rear support seat and left support seat are arranged on retainer ring respectively by T-slot; Rear supports is arranged on rear support seat, and left support body is arranged on left support seat.
As further improvement of the utility model, described clamp base adopts 6.
As further improvement of the utility model, described T-slot is circular arc.
As further improvement of the utility model, between described workpiece and sucker main shaft rotation center, adjust eccentric amount e.
Compared with the prior art the utility model has the following advantages:
The utility model is for the disadvantage of traditional structure, and when there is no the desirable electric magnetic no-core clamp for vertical grinder at home, a set of electric magnetic no-core clamp being applicable to vertical grinder of independent research, had both solved clamping quick position, and do not needed artificial centering; Employing excircle orientation supports, and required magnetic force is much smaller compared with magnechuck, solves again because magnetic force greatly easily causes a distortion difficult problem; Simultaneously because doing the axiality requirement of inside and outside circle of supporting position assurance with cylindrical.Owing to adopting two sleeve clamps to be supported on retainer ring, before and after it, angle, height adjustable.Be not in the mood for a fixture supports and be arranged to left supporting and rear support, expediently blanking; The inside and outside circle of energy clamped one time grinding work piece and end face; Its magnetic force size, eccentric size, height is adjustable, and after adjustment, locking can batch machining product, does not need to adjust again, facilitates machine operation and grinding.

Fig. 2 is the utility model electric magnetic no-core clamp structural front view.
Fig. 3 is the utility model electric magnetic no-core clamp structure top view.
Detailed description of the invention
Embodiment in is by reference to the accompanying drawings further described by the utility model below:
As Figure 1-3, lathe bed 1, rotary table 2, magnechuck 3, workpiece end face supporting 4, clamp base 5, retainer ring 6, rear support seat 7, rear supports 8, workpiece 9, bistrique 10, left support body 11, supporting mass 12 and left support seat 13 is comprised.
As shown in Fig. 2-Fig. 3, lathe bed 1 inside is provided with rotary table 2, and magnechuck 3 is arranged on rotary table 2, turns round around the alignment of shafts with rotary table.Workpiece end face supporting 4 is arranged on magnechuck 3, and can be adjustable in radial direction according to workpiece size.Workpiece 9 lower surface is bearing on end surface supporting 4 and also can slides on end surface supporting.
In the table rest outer of lathe bed 1,6 clamp base 5 are installed, Plane Installation fixture retainer ring 6 in clamp base 5, retainer ring 6 is provided with two circular arc T-slot, rear support seat 7 and left support seat 13 are arranged on retainer ring 6 by T-slot, its angle and front and back position adjustable according to workpiece size.Rear supports 8 is arranged on rear support seat 7, and left support body 11 is arranged on left support seat 13, and both can be regulated by screw positions different on supporting seat by height.
The utility model electric magnetic no-core clamp principle: as shown in Figure 1, workpiece is with external diameter and support end face on a left side for electric magnetic no-core clamp, on rear support body behind location, d-c solenoid is utilized to produce suction, workpiece end face is tightly inhaled on the end face of end surface supporting, and make to adjust certain eccentric amount e between workpiece 9 and sucker main shaft rotation center, when sucker rotates around its main shaft gyration axle center O, magnetic pole just makes workpiece rotate around itself center O ', owing to there being an eccentric amount e between the two, under centrifugal action, between magnetic pole and workpiece, end face produces relative sliding, so magnetic pole passes through O ' and perpendicular to the frictional force F of OO ' in the face of workpiece produces a moment of friction and one.The former makes workpiece turn round, and latter makes workpiece be close on two bearing contact, thus makes workpiece obtain stable gyration.
When workpiece 9 level is lifted in workpiece end face supporting 4, radial direction pushes two supporters 12 that adjusted puts in place to, comes to.Magnetic on magnechuck 3 on lathe, rotary work-table 2.Due to the effect of electromagnetic force and eccentric force, workpiece is just firmly axially positioned on end surface supporting 4; Be radially positioned in two not to be in the mood on supporting mass 12.At this moment bistrique 10 just can start to carry out grinding to the inside and outside circle of workpiece.Whole process is convenient, reliable.
