Abstract
The utility model provides a novel cylindrical grinding fixture comprising a lever, a mandrel, an elastic sleeve, a swivel nut, a first washer, a second washer, a check washer, a first nut, and a second nut. Both inner and outer cylindrical surfaces of the swivel nut are in threaded structures. The lever is fixedly connected with the mandrel which is connected with the swivel nut in a threaded manner. The first washer, the elastic sleeve, the second washer, the first nut, the check washer and the second nut sequentially sleeve the swivel nut; the swivel nut and the elastic sleeve are fixed into a whole. The first washer is disposed between the outer end face of the elastic sleeve and the end face of the swivel nut. The second washer is disposed between the outer end face of the elastic sleeve and the first nut. The check washer is disposed between the first nut and the second nut. The elastic sleeve and the swivel nut are fixedly connected into a whole by tightening force applied to the first nut and the second nut. The novel cylindrical grinding fixture is compact in structure, high in operating efficiency, high in machining precision and convenient to use, and product quality is stable.
Description
Technical field
The utility model relates to the technical field of fixture, relates in particular to a kind of Novel cylindrical grinding jig.
Background technology
At present, the technical scheme that circle hole type parts cylindrical grinding adopts is that tapering mandrel coordinates with part cylinder endoporus, but because tapering mandrel and part cylinder are that line contacts, contact area is little, and shakiness, causes processing parts cylindrical to beat greatly, and precision cannot ensure.
Summary of the invention
The utility model, in order to address the above problem, provides a kind of high-precision peripheral milling fixture.
The purpose of this utility model is achieved through the following technical solutions: a kind of Novel cylindrical grinding jig, comprise plate stem, mandrel, resilient sleeve, swivel nut, the first packing ring, the second packing ring, stop washer, the first nut, the second nut, swivel nut inner headed face and periphery are all helicitic textures, wherein plate stem is fixedly connected with mandrel, mandrel and swivel nut pass through thread connection, the first packing ring, resilient sleeve, the second packing ring, the first nut, stop washer, the second nut is enclosed within on swivel nut successively, swivel nut and resilient sleeve are fixed into an entirety, be, between resilient sleeve outer face and swivel nut end face, the first packing ring is installed, between resilient sleeve outer face and the first nut, the second packing ring is installed, between the first nut and the second nut, stop washer is installed, the power producing while relying on the first nut and the second nut screwing clamping is connected to one resilient sleeve and swivel nut.
The beneficial effects of the utility model are: compact overall structure, and operating efficiency is high, and machining accuracy is high, constant product quality, and use easily.
Brief description of the drawings
Fig. 1 is that master of the present utility model looks cutaway view.
Detailed description of the invention
Below in conjunction with embodiment, the utility model is described further.
Embodiment: a kind of Novel cylindrical grinding jig, comprise plate stem 1, mandrel 2, resilient sleeve 3, swivel nut 4, the first packing ring 5, the second packing ring 6, stop washer 7, the first nut 8, the second nut 9, swivel nut 4 inner headed faces and periphery are all helicitic textures, wherein plate stem 1 is fixedly connected with mandrel 2, mandrel 2 passes through thread connection with swivel nut 4, the first packing ring 5, resilient sleeve 3, the second packing ring 6, the first nut 8, stop washer 7, the second nut 9 is enclosed within on swivel nut 4 successively, swivel nut 4 is fixed into an entirety with resilient sleeve 3, be, between resilient sleeve 3 outer faces and swivel nut 4 end faces, the first packing ring 5 is installed, the second packing ring 6 is installed between resilient sleeve 3 outer faces and the first nut 8, stop washer 7 is installed between the first nut 8 and the second nut 9, the power producing while relying on the first nut 8 and the second nut 9 to tighten is connected to one resilient sleeve 3 and swivel nut 4.
When use, pulling plate stem 1 is with moving mandrel 2 to rotate, mandrel 2 rotations can make to produce axial displacement between mandrel 2 and resilient sleeve 3, it is outwards swollen until closely cooperate with part that when mandrel 2 is shifted to elasticity 3 and overlapped, the outer conical surface of mandrel 2 can promote resilient sleeve 3, thereby realizing mandrel 2 coordinates with the gapless of inner bore of part, when mandrel 2 moves apart resilient sleeve 3, resilient sleeve 3 is shunk with inner bore of part and is formed gap, and part can take off.
Claims (1)
1. a Novel cylindrical grinding jig, comprise mandrel, it is characterized in that: also comprise plate stem, resilient sleeve, swivel nut, the first packing ring, the second packing ring, stop washer, the first nut, the second nut, swivel nut inner headed face and periphery are all helicitic textures, wherein plate stem is fixedly connected with mandrel, mandrel and swivel nut are by thread connection, and the first packing ring, resilient sleeve, the second packing ring, the first nut, stop washer, the second nut are enclosed within on swivel nut successively, and swivel nut and resilient sleeve are fixed into an entirety.
