Abstract
The invention relates to a power-driven device for grinding a valve element of a stop valve. The device is used for grinding the valve element of the stop valve. The power-driven device comprises a rack, a motor, a speed reducer, a gear, an abrasive paper bottom plate, abrasive paper and an abrasive paper cover plate. The motor and the speed reducer are located below a supporting plate of the rack, the gear is located above the supporting plate, the motor output drives the gear to rotate after speed changing of the speed reducer, the abrasive paper bottom plate is fixedly installed on the gear, the abrasive paper cover plate is fixedly installed on the abrasive paper bottom plate, the abrasive paper is arranged between the abrasive paper bottom plate and the abrasive paper cover plate, a grinding hole is formed in the abrasive paper cover plate, and the valve element is located in the grinding hole and ground by the abrasive paper. According to the power-driven device for grinding the valve element of the stop valve, power-driven valve element grinding is achieved, manual grinding is replaced, the labor intensity is relieved, the working efficiency is improved, valve elements of stop valves with different diameters can be ground, and the grinding effect is good.
Description
Technical field
The present invention relates to lapping device field, be specifically related to a kind of device of electric grinding stop valve spool.
Background technology
The pipeline of boiler and boiler fixture thereof is nearly all provided with the stop valve of high temperature, high pressure, and therefore concerning boiler, the tightness of valve is particularly important.
According to statistics, stop valve on boiler and boiler fixture pipeline thereof has DN15, DN20, DN25, DN32, DN50, DN65, DN100, the valve of 7 kinds of different latus rectums, its quantity about more than 80, kind is many, quantity is large, and existing be all hand lapping to the spool of stop valve, length consuming time, hand lapping labour intensity is large.
Summary of the invention
For solving the problem, technical problem to be solved by this invention is to provide a kind of device of electric grinding stop valve spool.
The technical scheme that the present invention solves the problems of the technologies described above is as follows: a kind of device of electric grinding stop valve spool, this device is for grinding the spool of stop valve, comprise frame, motor, decelerator, gear, sand paper base plate, sand paper and sand paper cover plate, the top of described frame is provided with gripper shoe, described motor and described decelerator are in described frame, and be positioned at the below of described gripper shoe, described gear is in the top of described gripper shoe, described motor exports and drive described pinion rotation after described decelerator speed change, described gear fixedly mounts described sand paper base plate, described sand paper base plate fixedly mounts described sand paper cover plate, described sand paper is provided with between described sand paper base plate and described sand paper cover plate, and on sand paper cover plate, be provided with grinding hole, described spool is in described grinding hole and is ground it by described sand paper.
Further, described frame is also provided with the described gauge tap controlling described motor and open and close.
Further, described sand paper base plate is fixedly mounted on described gear by dormant bolt I, and described sand paper cover plate is fixedly mounted on described sand paper base plate by dormant bolt II.
The invention has the beneficial effects as follows: the device of a kind of electric grinding stop valve spool provided by the invention, realizes electric grinding spool, thus substitute hand lapping, reduce labor intensity, increase work efficiency, and can grind the spool of different latus rectum stop valve, grinding effect is good.
Accompanying drawing explanation
Fig. 1 is overall structure schematic diagram of the present invention.
In accompanying drawing, the list of parts representated by each label is as follows:
1, frame, 2, motor, 3, decelerator, 4, gear, 5, sand paper base plate, 6, sand paper, 7, sand paper cover plate, 8, grinding hole, 9, dormant bolt I, 10, dormant bolt II, 12, spool, 13, gauge tap.
Detailed description of the invention
Be described principle of the present invention and feature below in conjunction with accompanying drawing, example, only for explaining the present invention, is not intended to limit scope of the present invention.
As shown in Figure 1, a kind of device of electric grinding stop valve spool, this device is for grinding the spool of stop valve, comprise frame 1, motor 2, decelerator 3, gear 4, sand paper base plate 5, sand paper 6 and sand paper cover plate 7, the top of described frame 1 is provided with gripper shoe 11, described motor 2 and described decelerator 3 are in described frame 1, and be positioned at the below of described gripper shoe 11, described gear 4 is in the top of described gripper shoe 11, the output of described motor 2 drives described gear 4 to rotate after described decelerator 3 speed change, described sand paper base plate 5 is fixedly mounted on described gear 4 by dormant bolt I 9, described sand paper cover plate 7 is fixedly mounted on described sand paper base plate 5 by dormant bolt II 10, described sand paper 6 is provided with between described sand paper base plate 5 and described sand paper cover plate 7, and on described sand paper cover plate 7, be provided with grinding hole 8, described spool 12 is in described grinding hole 8 and is ground it by described sand paper 6.
When processing sand paper base plate 5, require that the plane of sand paper base plate 5 and vertical precision ensure the abradant surface not run-off the straight of described sand paper base plate 5 and described spool 12.The sand paper base plate 5 processed and sand paper cover plate 7 are connected, and between sand paper base plate 5 and sand paper cover plate 7, put sand paper 6 well and clamp,
Described frame 1 is also provided with the described gauge tap 13 controlling described motor 2 and open and close, with hand-held steady spool 12, it is made to be in grinding hole 8, and ensure that the abradant surface of spool 12 contacts with sand paper 6, open motor 2 by gauge tap 13 to run, sand paper 6 forms pivoting friction with the abradant surface of spool 12, thus the rust grinding on spool 12 abradant surface and pit hot spot thereof, reach the object of electric grinding spool 12.The transmission of electric grinding stop valve spool machine and decelerator 3 mechanism adopt the driving mechanism of waste and old electric block, contrast as calculated, and the velocity of rotation of output to turn left the right side than underhand polish spool speed many 10 just, meets the requirement of grinding spool speed.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
