Description
Technical field
This utility model is related to part processing clamping engineering device technique field, more specifically, it relates to a kind of jig.
Background technology
Fixture is for fixing processing object during machine-building, allows processing object occupy correct position, to accept
Processing, makes the surface energy of processing object reach the dimensions that drawing specifies, geometry and the mutual alignment essence with other surfaces
The instrument of the technical requirements such as degree.
During processing criterion part, generally use universal fixturing, universal fixturing can process different works within the specific limits
Part, adaptability is wider.But when surface of the work has one side to be curved surface, fixture just can not clamp and fixing workpiece well, impact
Crudy.
Content of the invention
The purpose of this utility model is to provide a kind of jig that can clamp curve surface work pieces.
Above-mentioned technical purpose of the present utility model technical scheme is that：
A kind of jig, including clamp body, the location-plate located at clamp body two ends, the gripping block on location-plate,
Described gripping block surface is provided with the projection being wholely set with gripping block, and lug surface is provided with one layer of cushion；Gripping block is provided with
Projection one is arranged facing to location-plate.
It is arranged such, when surface of the work is curved surface, fixture clamping workpiece, the cushion of lug surface is occurred with absorption surface
Deformation, surface of the work of fitting, reach the purpose of clamping curve surface work pieces；And can be reduced during clamping workpiece to work using cushion
The damage that part surface produces.
Arrange further：Described cushion is made using elastomeric material.
It is arranged such, because rubber has higher elasticity at normal temperatures, slightly carry plasticity, protection surface of the work is had
Good effect, and rubber has extraordinary mechanical strength, and hysteresis loss is little, and flexible resistance is also fine, is hardly damaged, no
Need often to change, reduces cost.
Arrange further：It is provided with axial height adjusting means in described gripping block, adjust including the screw thread through adjustment hole
Nodal axisn, it is set on threaded adjusting axle and contacts at the regulating bolt that gripping block deviates from lug surface.
It is arranged such, the height of gripping block can change to adjust with workpiece height, and gripping block is adjacent to workpiece all the time, reaches
To best clamping effect；Location-plate, gripping block can be connected by threaded adjusting axle and regulating bolt simultaneously, convenient
Operator's tightening and loosening.
Arrange further：Described gripping block is provided with radial orientation adjustment unit, oval including the regulation penetrating gripping block
Hole.
It is arranged such, gripping block can move radially around adjustment axis, the change with diameter of work adjusts gripping block and work
The contact point of part, to coordinate the size of clamped part, reaches optimal clamping effect, expands the scope of application of fixture.
Arrange further：Described clamp body and location-plate correspondence position are provided with connecting hole.
It is arranged such, clamp body and location-plate can be connected by fastening, spacing location-plate simultaneously, anti-fastening by connecting hole
Movement during the plate work of position.
Arrange further：Described gripping block and regulating bolt resistance surface are provided with metal washer.
It is arranged such, metal washer can disperse the pressure to gripping block surface for the threaded adjusting axle, in order to protect gripping block
Surface is not abraded by threaded adjusting axle, increases the service life of gripping block, and increases fastening effect.
Arrange further：It is provided with the alignment pin intercommunicating pore penetrating clamp body in the middle of described clamp body.
It is arranged such, can be secured fixtures on lathe using alignment pin by alignment pin intercommunicating pore, and can determine
Position fixture and the relative position of lathe.
As preferred：Described clamp body surface Chang Bian side is provided with the specific stopper slot of fixation clamp.
It is arranged such, the position of fixture when securing fixtures on lathe, can be limited by stopper slot, reduce fixture in work
The movement being produced because impacting when making, increases the accuracy of part processing.
In sum, this utility model has the advantages that：It is the workpiece of curved surface that wherein one side can be clamped, and reduces
The damage to surface of the work for the gripping block, strengthens the effect of clamp workpiece, limits chucking position, prevents displacement, increases part
The accuracy of processing.

Specific embodiment
With reference to Fig. 1 to Fig. 3, a kind of jig is described further.
Embodiment 1：A kind of jig, as shown in figure 1, include clamp body 1, located at clamp body 1 two ends by connect
The location-plate 2 that hole 5 is connected, the gripping block 3 on location-plate 2, gripping block 3 be provided with projection 31 facing to location-plate 2
Setting.
Referring to Fig. 2, above-mentioned gripping block 3 is provided with projection 31, and projection 31 surface is provided with cushion 32, when workpiece 10 and elasticity
During pad 32 contact, cushion 32 deforms upon, and reduces the pressure to workpiece 10 surface, protect workpiece 10 while fastening workpiece 10
Shape.
Embodiment 2：A kind of jig, as shown in figure 3, being with the difference of embodiment 1, is provided with gripping block 3
