Abstract
A kind of valve body hole hone, belong to a kind of abrasive machining tool, comprise handle of a knife and honing head, wherein, the lower end of handle of a knife is connected with candan universal joint, and honing head is connected to the lower end of candan universal joint by pin, and the lower end of honing head is provided with guide section.The advantage of the utility model valve body hole hone is: valve opening not only machining accuracy is high, and machining accuracy is stable, working (machining) efficiency is high, is applicable to large batch of processing.
Description
Technical field:
The utility model relates to a kind of abrasive machining tool, is specifically a kind of valve body hole hone.
Background technology:
In various valve body processing, the processing of valve opening is a very crucial operation, require that the fit clearance of valve rod and valve opening controls in 0.008 ~ 0.012mm, this just requires that the machining accuracy of valve opening wants high, and will ensure that the dimensional accuracy of valve opening and form and position tolerance require very high to processing technology and machining tool.The processing method of current valve opening is: first on a machine tool equipment through bore hole, and then to ream, stay 0.03mm mill amount after fraising, finally move to this hole of honing head honing with one group of three different accuracy on next device again.When honing valve opening, common method is directly contained in by hone in radial drill spindle taper hole or by gearbox horizontal machine retardation level to be directly contained on electric machine main shaft, so substantially, meet processing request, but also have many weak points: because this honing operation is secondary clamping, it is be rigidly connected that hone is contained in radial drill spindle taper hole, and therefore, the honing head on hone and valve body hole are difficult to aim at, hole dimension uniformity after honing is poor, and there is scuffing fineness local; Even if honing head is contained on horizontal machine main shaft, catches valve body workpiece honing valve opening effect quite a lot of with hand, but catch valve body workpiece firmly uneven with hand, simultaneously also danger close, if the very large hand of resistance is grabbed and tightly can not be injured in one's hands, have hidden danger.When honing valve opening, working (machining) efficiency is lower, precision is unstable for above-mentioned two kinds of methods, is difficult to meet the needs produced in enormous quantities.
Utility model content:
The technical problems to be solved in the utility model is, when providing a kind of valve opening on honing valve body, not only machining accuracy is high, and the valve body hole hone that machining accuracy is stablized, working (machining) efficiency is high.
Technical solution of the present utility model is, provides a kind of valve body hole hone, comprises handle of a knife and honing head, wherein, the lower end of handle of a knife is connected with candan universal joint, and honing head is connected to the lower end of candan universal joint by pin, and the lower end of honing head is provided with guide section.
Valve body hole hone described in the utility model, wherein, on guide section, cover has needle bearing, and the upper end of needle bearing withstands on the step surface on guide section, and the lower end of needle bearing is pressed on the elastic spring that guide section is provided with.
Valve body hole hone described in the utility model, wherein, honing head periphery is electroplate with one deck diamond particles.
Valve body hole hone described in the utility model, wherein, honing head periphery is provided with spiral groove.
Valve body hole hone described in the utility model, wherein, the top periphery of guide section is provided with annular groove, and the bottom surface of guide section is provided with axial hole, and axial hole communicates with annular groove.
After adopting above structure, compared with prior art, the utility model valve body hole hone has the following advantages: because the lower end of handle of a knife is connected with candan universal joint, honing head is connected to the lower end of candan universal joint by pin, the lower end of honing head is provided with guide section, therefore, when the utility model valve body hole hone is arranged on upright drill, when carrying out the valve opening on honing valve body, the torsion of drilling machine is floated by candan universal joint and passes to honing head, and by guide section automatically and the valve opening centering that on valve body, roughing goes out, the centering precision of honing head and valve opening is high, clamping workpiece is convenient, do not need each valve body workpiece centering one by one, valve opening not only machining accuracy is high, and machining accuracy is stablized, working (machining) efficiency is high, be applicable to large batch of processing.Honing head is connected to the lower end of candan universal joint by pin in addition, can also change the honing head of different accuracy easily and fast.
The effect of the needle bearing that guide section is provided with is: because only have rolling friction between needle bearing and valve opening, therefore, can prevent the guide section on honing head from being scratched by valve opening.
Effect honing head periphery being electroplate with one deck diamond particles is: because the hardness of diamond particles is comparatively large, when processing valve opening, can cut very fast, and wear-resistant, and the processing dimension uniformity of valve opening is better.
The effect that honing head periphery is provided with spiral groove is: when processing valve opening, grinding oil can be taken out of the foreign material of grinding very easily by spiral groove.
The effect of axial hole and annular groove is: when processing valve opening, facilitate the discharge of grinding oil.
Accompanying drawing illustrates:
Fig. 1 is the main TV structure schematic diagram of the utility model valve body hole hone.
Detailed description of the invention:
Below in conjunction with the drawings and specific embodiments, the utility model valve body hole hone is described further:
As shown in Figure 1, the utility model valve body hole hone comprises handle of a knife 1 and honing head 3, the lower end of handle of a knife 1 is connected with candan universal joint 2, honing head 3 is connected to the lower end of candan universal joint 2 by pin 6, the lower end of honing head 3 is provided with guide section 4, on guide section 4, cover has needle bearing 5, the upper end of needle bearing 5 withstands on the step surface on guide section 4, the lower end of needle bearing 5 is pressed on the elastic spring 11 that guide section 4 is provided with, honing head 3 periphery is electroplate with one deck diamond particles 8, honing head 3 periphery is provided with spiral groove 7, the top periphery of guide section 4 is provided with annular groove 9, the bottom surface of guide section 4 is provided with axial hole 10, axial hole 10 communicates with annular groove 9.
Above-described specific embodiment is only be described preferred embodiment of the present utility model; not scope of the present utility model is limited; under the prerequisite not departing from the utility model design spirit; the various distortion that those of ordinary skill in the art make the technical solution of the utility model and improvement, all should fall in protection domain that the utility model claims determine.
