Abstract
The utility model discloses a grinding machine tool fixture which comprises a center shaft, positioning shafts and a lock nut. One end part of the center shaft is provided with a limiting ring in the peripherical direction; both ends of the center shaft are respectively provided with internal screw thread holes along the center lines; two positioning shafts are provided and are respectively screwed in the internal screw thread holes by external screw threads; the outer ends of the positioning shafts are provided with center positioning holes along the center lines; the excircle of the other end part of the center shaft is provided with an external screw thread; and the other end of the center shaft is sleeved with the lock nut in a screwed manner. Both ends of the center shaft are respectively provided with the internal screw thread holes along the center lines, the positioning shafts are screwed in the internal screw thread holes, the outer ends of the positioning shafts are provided with the center positioning holes along the center lines, the grinding machine tool fixture is matched with a grinding machine to carry out positioning by the center positioning holes of the positioning shafts, and when the center positioning holes are worn, only the positioning shafts need to be replaced without processing the center shaft, therefore, the grinding machine tool fixture not only is rapid and convenient, but also saves cost and improves production efficiency.
Description
Technical field
The utility model relates to a kind of frock clamp, relates in particular to a kind of grinding machine frock clamp.
Background technology
Often need the processing cover parts in machine-building.The demanding cover parts work in-process of dimensional accuracy and roughness need to just can be completed through grinding.Because the general wall thickness dimension of cover parts is less, the clamping difficulty, and easily deform.In order to guarantee to process the part that meets designing requirement, often need to design cover parts is fixed on grinding machine frock clamp on the grinding machine positioning center hole.
In prior art, grinding machine frock clamp mainly adopts central shaft, and the two ends of central shaft arrange center positioning hole along center line, and cover parts to be ground is sleeved on central shaft, then the center positioning hole of central shaft is fixed by the top on grinding machine.Use above-mentioned grinding machine frock clamp mainly to have following defective: frock clamp is along with the growth of time, the center positioning hole at central shaft two ends weares and teares gradually, therefore, must regularly carry out machining to the two ends of central shaft, again bore center positioning hole, like this, both be difficult to guarantee the coaxial precision of the each center positioning hole that bores in central shaft two ends, and long processing time, production cost is high, efficient is low.
The utility model content
For above-mentioned the deficiencies in the prior art part, the utility model provides a kind of need not to process the grinding machine frock clamp that just can guarantee than high-axiality to central shaft, uses this grinding machine frock clamp cost low, and efficient is high.
In order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
A kind of grinding machine frock clamp comprises central shaft, locating shaft and locking nut; One end of described central shaft arranges spacing ring along its circumferencial direction, is respectively equipped with internal thread hole at the two ends of central shaft along center line; Locating shaft is two, is combined in internal thread hole by external thread rotary respectively, and the outer end of locating shaft arranges center positioning hole along center line; The other end cylindrical of described central shaft arranges external screw thread, and the locking nut rotation set is on the other end of central shaft.
As a kind of preferred version of the present utility model, described locating shaft is regular polygon near the outer circle cross-section of centralized positioning nose end.
The beneficial effects of the utility model are: the two ends at central shaft are respectively equipped with internal thread hole along center line, screw locating shaft in internal thread hole, the outer end of locating shaft arranges center positioning hole along center line, center positioning hole by locating shaft coordinates the location with grinding machine, during the center positioning hole wearing and tearing, only need to change locating shaft, need not central shaft is processed, both quick and easy, save again cost simultaneously, enhance productivity.
Description of drawings
Fig. 1 is a kind of structural representation of grinding machine frock clamp.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As shown in Figure 1, a kind of grinding machine frock clamp comprises central shaft 1, locating shaft 2 and locking nut 3.One end of central shaft 1 arranges spacing ring 8 along its circumferencial direction, is respectively equipped with internal thread hole 4 at the two ends of central shaft 1 along center line.Locating shaft 2 is two, is combined in internal thread hole 4 by external thread rotary respectively, and the outer end of locating shaft 2 arranges center positioning hole 5 along center line.The other end cylindrical of central shaft 1 arranges external screw thread, and locking nut 3 rotation sets are on the other end of central shaft 1.
Carry out installation or removal for the ease of locating shaft 2, locating shaft 2 is that regular polygon 7(the present embodiment is processed into orthohexagonal near the outer circle cross-section of center positioning hole 5 ends).
When using this fixture, at first at close locating shaft 2 and being tightened of internal thread hole 4 inward turnings at central shaft 1 two ends; Then cover parts to be ground 6 is sleeved on central shaft 1, on the spacing ring 8 of the end by central shaft 1 and the other end, the locking nut 3 of rotation set is axially fixed in cover parts 6 on central shaft 1, at last the center positioning hole 5 of locating shaft 2 top with grinding machine is fixed.After center positioning hole 5 wearing and tearing of locating shaft 2, only need it is screwed off, from new installation locating shaft 2.
Explanation is at last, above embodiment is only unrestricted in order to the technical solution of the utility model to be described, although with reference to preferred embodiment, the utility model is had been described in detail, those of ordinary skill in the art is to be understood that, can modify or be equal to replacement the technical solution of the utility model, and not breaking away from aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of claim scope of the present utility model.
