Description
Technical field
The utility model relates to Machining Technology field, specifically relates to a kind of cover parts cylindricalo grinding frock.
Background technology
Cover parts refers to porose part, is widely used in machinery industry.Yet the outer round surface of cover parts need to carry out grinding on plain external grinding machine, so the clamping of cover parts is the requisite link of grinding.At present grinding machine normally adopts scroll chuck clamping workpiece, or adopts the two top dependence heart cover tensioner workpiece that rises.Although adopt the above-mentioned installation way can be to its fixation of workpiece, clamping be inconvenient, and working (machining) efficiency is low, and workpiece easily produces distortion in process, thereby reduce, makes product percent of pass, is difficult to guarantee that processing carries out smoothly.
Utility model content
In order to address the above problem, the utility model provides a kind of cover parts cylindricalo grinding frock, thereby has solved the problem of cover parts clamping difficulty, has guaranteed carrying out smoothly of cover parts Excircle machining.
The utility model is achieved by following technical solution.
A kind of cover parts cylindricalo grinding frock, comprise axle body, resilient sleeve and gland, described axle body is comprised of construction section and the polished rod section and the thread segment that are positioned at construction section two ends, described resilient sleeve is sleeved on the construction section outside of axle body, on described thread segment, be provided with external screw thread, gland is connected by internal thread and the external screw thread of the portion of setting within it.
Described construction section is truncated cone-shaped structure, at the large end of truncated cone-shaped structure, is provided with step.
Described resilient sleeve is the loop configuration of boring, and boring is partly set to the interior round table surface that truncated cone-shaped structural outer surface matches.
The end face of described polished rod section and thread segment is equipped with centre bore.
Described gland is provided with outer-hexagonal.
Described resilient sleeve is provided with breach.
The beneficial effects of the utility model are:
Compared with prior art, the utility model by arranging resilient sleeve on axle body, and lock by gland, because adopting round table surface, the installed surface of resilient sleeve and axle body coordinates, make resilient sleeve and axle body on mating surface, form wedge structure, in tightening the process of gland, make axle body and resilient sleeve produce relative motion, make resilient sleeve distortion open generation clamping force, thus clamping work pieces.Adopt the utility model not only can guarantee machining accuracy, and greatly improved production efficiency, meanwhile, can effectively prevent that workpiece from producing distortion in process, improves the quality of products.The utility model is simple in structure, easy to use, can be widely used in grinding cover parts on plain external grinding machine.

The specific embodiment
Below in conjunction with accompanying drawing, further describe the technical solution of the utility model, but described in claimed scope is not limited to.
As shown in Figures 1 to 7, a kind of cover parts cylindricalo grinding frock described in the utility model, comprise axle body 1, resilient sleeve 2 and gland 3, described axle body 1 is comprised of construction section 12 and the polished rod section 11 and the thread segment 13 that are positioned at construction section 12 two ends, described resilient sleeve 2 is sleeved on construction section 12 outsides of axle body 1, on described thread segment 13, be provided with external screw thread 131, gland 3 is connected with external screw thread 131 by the internal thread 31 of the portion of setting within it.Adopt the technical program, by resilient sleeve 3 is installed on axle body 1, on adopting plain external grinding machine, during grinding cover parts, cover parts to be processed is arranged on to resilient sleeve 3 outsides, not only can guarantee machining accuracy, and greatly improve production efficiency.Meanwhile, with this type of elasticity frock clamping grinding thin-wall sleeve parts, can effectively prevent workpiece deformation, obtain good effect.
Described construction section 12 is truncated cone-shaped structure 122, at the large end of truncated cone-shaped structure 122, is provided with step 121.Like this, in use, can be undertaken by 121 pairs of resilient sleeve of step 2 spacingly, by gland 3 extruding, resilient sleeve is locked between step and workpiece.
The loop configuration that described resilient sleeve 2 is boring, and boring is partly set to the interior round table surface 21 that truncated cone-shaped structure 122 outer surfaces match.Wherein resilient sleeve 2 outer surfaces are the face of cylinder matching with workpiece 5 inner surfaces, can make like this resilient sleeve 2 form wedge structures, make resilient sleeve 2 produce outside tension force in the compaction process of gland 3, effectively prevent that workpiece 5 from producing distortion in process.
The end face of described polished rod section 11 and thread segment 13 is equipped with centre bore 4.The effect of centre bore 4 is during for grinding and clamping, is convenient to the top installation location to grinding machine.
Described gland 3 is provided with outer-hexagonal 31.While being convenient to gland 3 is installed like this, adopting spanner to snap in outer-hexagonal 32 and tighten gland 3.
Described resilient sleeve 2 is provided with breach 22.Like this can be so that the installation of resilient sleeve 2 can make resilient sleeve 2 have larger shrinkage simultaneously.
As shown in Fig. 2, Fig. 6, while adopting the utility model to carry out grinding outer round surface to workpiece 5, first workpiece 5 is sleeved in resilient sleeve 2, again resilient sleeve 2 and workpiece 5 are packed into the construction section 12 of axle body 1, finally the internal thread 31 of gland 3 is screwed in to the external screw thread 131 of axle body 1, with spanner, snap in outer-hexagonal 32 and tighten gland 3, workpiece 5 and step 121 are adjacent to, impel construction section 12 and resilient sleeve 2 relative motions of axle body 1, in the process of relative motion, make resilient sleeve 2 distortion open generation clamping force, thus clamping work pieces 5; Now, the centre bore 4 arranging with polished rod section 11 and thread segment 13 end faces of the top aligning axle body 1 of two grinding machines, clamping grinding fixture described in the utility model, and installing after driver plate, can be on cylindrical grinder grinding work piece 5.On plain external grinding machine, with this frock clamping grinding cover parts, not only can guarantee machining accuracy, and improve production efficiency.Meanwhile, with this type of elasticity frock clamping grinding thin-wall sleeve parts, can effectively prevent workpiece deformation, obtain good effect.
