Utility model content
The technical problems to be solved in the utility model: provide a kind of Self-sealing valve lapping device, to solve in process of lapping the requirement of operator's level of skill is higher and working (machining) efficiency is low, cost high problem.
The technical solution of the utility model:
A kind of Self-sealing valve lapping device, for grinding the inner cylinder face of part and inner conical surface, comprising:
Grinding stand, in spill, has symmetrical first lug boss and the second lug boss, forms a grinding chamber between described first lug boss and the second lug boss;
Power transmission shaft, by one end through described first lug boss, be arranged in described first lug boss rotationally, the described end of described power transmission shaft is positioned at described grinding chamber, and described end has the clamping part matched with part shape;
Motor, is connected by the other end of output shaft with described power transmission shaft;
Finial device, be arranged in described second lug boss, described Finial device has telescopic top, is describedly toply positioned at described grinding chamber, and, described top and described power transmission shaft coaxial line.
Alternatively, the described output shaft of described motor is connected with described power transmission shaft by shaft coupling.
Alternatively, be provided with axle sleeve in described first lug boss, described power transmission shaft is arranged in described axle sleeve rotationally by bearing.
Alternatively, described sleeve end is provided with locking nut.
Alternatively, described Finial device also comprises for regulating described top regulating handle, and described regulating handle is positioned at one end of described second lug boss described grinding chamber dorsad.
The beneficial effects of the utility model: Self-sealing valve lapping device structure of the present utility model is simple, and easy to operate, grinding precision is high, are applicable to batch production type; Grinding axiality can also be solved require higher and produce, cost high problem low to higher, the traditional engine lathe lapping efficiency of operator's level of skill requirement, thus the requirement reduced operator's level of skill, shorten the attrition process time of part, improve working (machining) efficiency, effectively reduce processing cost.
Accompanying drawing explanation
Fig. 1 is the utility model Self-sealing valve lapping device front view;
Fig. 2 is the sectional view on the utility model Self-sealing valve lapping device front view basis;
Fig. 3 is the utility model Self-sealing valve lapping device top view.
Detailed description of the invention
Below in conjunction with accompanying drawing, the Self-sealing valve lapping device involved by the utility model is described in further details.
As shown in Figure 1, 2, 3, Self-sealing valve lapping device of the present utility model, for grinding the inner cylinder face of part and inner conical surface, comprising grinding stand 5 and being arranged on grinding stand 5 and uploading moving axis 6 and Finial device.It should be noted that, Fig. 2 is the sectional view on the utility model Self-sealing valve lapping device front view basis, and wherein front view is not shown.
Wherein, grinding stand 5 is in spill, and have symmetrical first lug boss and the second lug boss, form a grinding chamber between the first lug boss and the second lug boss, the processing of part is mainly carried out in this grinding chamber.
Power transmission shaft 6, is arranged in the first lug boss through the first lug boss rotationally by one end.The above-mentioned end of power transmission shaft 6 is positioned at grinding chamber, and this end has the clamping part matched with part shape, for holding parts.In addition, cause damage to the first lug boss in order to prevent power transmission shaft 6 from rotating for a long time in wearing and tearing and rotation process, be also provided with axle sleeve 4 in the first lug boss, power transmission shaft 6 is arranged on the stepped hole at axle sleeve 4 two ends rotationally by bearing 9.Axle sleeve 4 end is provided with again locking nut 3, for being fixed axle sleeve 4, prevents axle sleeve 4 axial float.
Motor 1, is connected by the other end of output shaft with power transmission shaft 6.Wherein, output shaft can also be connected with power transmission shaft 6 by shaft coupling 2, drives power transmission shaft 6 to rotate by shaft coupling 2.
Finial device is arranged in the second lug boss, Finial device have can axial stretching top 7, top 7 are positioned at grinding chamber.Top 7 with power transmission shaft 6 coaxial line, ensure grinding axiality requirement.By the acting in conjunction of above-mentioned power transmission shaft 6 clamping part and top 7, part is clamped, make part follow power transmission shaft 6 and rotate together, with to be processed.
Finial device also comprises the regulating handle 8 for regulating top 7, and regulating handle 8 is positioned at one end of the second lug boss grinding chamber dorsad.Wherein, the outer surface middle of Finial device is provided with locking screw pit, and equally, inherent Finial device one end of the second lug boss of grinding stand is provided with locking screw pit, and when after top 7 axial locations of regulating handle adjustment, locking screw pit carries out axial locking.
During grinding, first grinding part is installed on the clamping part of power transmission shaft 6, is adjusted the axial location of top 7 by regulating handle 8, utilize top 7 part is carried out axial restraint, by locking screw pit locking top 7 after fixing; Open motor 1 again, adjusting to grinding rotating speed is 15r/min, carries out attrition process; Fineness Ra0.4 requirement needed for part can be reached after attrition process is about 24h.
Lapping device of the present utility model solves grinding inner cylinder face, inner conical surface part requires the problem higher, working (machining) efficiency is low, cost is high to operator's level of skill, thus the requirement reduced operator's level of skill, improve working (machining) efficiency, reduce processing cost, and ensure that product quality.This apparatus structure is simple, and easy to operate, grinding precision is high, is applicable to batch production type.
The above is only preferred embodiment of the present utility model; it should be pointed out that for those skilled in the art, do not departing under the original prerequisite of the utility model; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
