Abstract
The invention discloses a valve grinding machine which comprises a motor. A chuck and a handheld sleeve are sequentially connected below the motor, a grinding disc and a pressing plate are sequentially connected below the handheld sleeve, a pressure adjusting device above the grinding disc is further connected to the handheld sleeve, the pressure adjusting device comprises a pressure adjusting handle, the pressure adjusting handle is mounted on a pressure adjusting screw cap, an adjustable support is connected below the pressure adjusting screw cap, and the adjustable support is fixed on a fixing placement base through a bolt. The pressure adjusting device is arranged on an existing valve grinding machine, action force exerted on the grinding disc can be adjusted through the pressure adjusting handle, the phenomenon that the action force on the grinding disc is too large or too small can be avoided, therefore, grinding work is facilitated better, and the valve grinding machine is convenient and rapid to use.
Description
Technical field
The present invention relates to a kind of valve grinding machine, be specifically related to a kind of valve grinding machine for stop valve.
Background technology
Grinding-in of valve is exactly the grinding to valve sealing face, the grinding of valve sealing face is not that grinding head or grinding base directly contact mill with polished flap, valve seat, but to pad or spread one deck grinding-material, to utilize the particulate that grinding-material hardness is high that abrasive article is polished.
Existing a kind of valve grinding machine can not be controlled the power of grinding, and the dynamics that is easy to not reach grinding requires or the excessive and damage valve of the dynamics of grinding.
Summary of the invention
The invention provides a kind of valve grinding machine, can solve the problem of adjusting grinding pressure size when grinding, reach the object of better grinding valve.
Object of the present invention reaches by the following technical programs:
A kind of valve grinding machine, comprise motor, motor below is connected with chuck, hand-held cover in turn, hand-held cover below is connected with abrasive disk, pressing plate in turn, hand-held putting is also connected with the pressure regulation device that is positioned at abrasive disk top, and described pressure regulation device comprises pressure adjustment handle and adjustable support, and pressure is adjusted handle and is arranged on pressure adjustment spiral cover, pressure is adjusted spiral cover below and is connected with adjustable support, and adjustable support is bolted on fixedly on swing seat.
Described fixedly swing seat comprises fixedly swing seat, lower fixedly swing seat, and upper fixedly swing seat and lower fixedly swing seat bolt link together.
Described pressing plate is sand paper pressing plate, emery cloth pressing plate or abrasive sand pressing plate.
Described abrasive disk is connected with hand-held cover bolt.Abrasive disk is connected G and according to the valve seat of different model size, changes the size of abrasive disk with hand-held cover bolt, convenient and swift more practical.
Adjustable support is provided with fixed support plate adjustable support is arranged on fixedly on swing seat.Fixed support plate mainly plays the effect of compression adjustable support is fixed.
It is 2 or 3 that described pressure is adjusted handle.
The present invention compared with prior art, there is following advantage and beneficial effect:
The present invention is provided with a pressure regulation device on existing a kind of valve grinding machine, can adjust handle adjusting by pressure and be applied to the active force on abrasive disk, can avoid the active force of abrasive disk excessive or too small, thereby more be conducive to the carrying out of the work of grinding, conveniently.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Wherein, the parts title that Reference numeral is corresponding is as follows:
1-motor, the hand-held cover of 2-, 3-pressure are adjusted handle, 4-adjustable support, 5-fixedly fixedly swing seat, 6-valve, 7-abrasive disk, 8-pressing plate under swing seat, the upper fixedly swing seat of 501-, 502-.
The specific embodiment
Below in conjunction with embodiment, the present invention is described in further detail, but embodiments of the present invention are not limited to this.
Embodiment 1
As shown in Figure 1, a kind of valve grinding machine, comprise motor 1, motor 1 below is connected with chuck, hand-held cover 2 in turn, and hand-held cover 2 belows are connected with abrasive disk 7, pressing plate 8 in turn, on hand-held cover 2, are also connected with the pressure regulation device that is positioned at abrasive disk 7 tops, described pressure regulation device comprises pressure adjustment handle 3 and adjustable support 4, pressure is adjusted handle 3 and is arranged on pressure and adjusts on spiral cover, and pressure is adjusted spiral cover below and is connected with adjustable support 4, and adjustable support 4 is bolted on fixedly on swing seat 5.
The present embodiment is a kind of valve grinding machine for stop valve, the stop valve that is plane for the sealing surface of valve seat, flap, and pressing plate is gauze pressing plate; The stop valve that is the conical surface for the sealing surface of valve seat, flap, pressing plate is emery cloth pressing plate.During enforcement, first fixing swing seat 5 mounted valve 6 tops.Whole fixedly swing seat 5 is for pressure regulation device provides support, and fixedly swing seat 5 is connected with valve 6 bolts, and when rotational pressure adjustment handle is adjusted whole grinding pressure, fixedly swing seat 5 can provide support power to pressure regulation device.
Handle by motor 1 by lapping device toward pressing down, Deng pressing down after a segment distance, rotation pressure is adjusted handle 3 gently, abrasive disk 7 and the face to be processed of hand-held cover 2 lower ends are affixed, sensation compresses gently, avoid damaging valve seat, start motor 1, make abrasive disk 7 rotations get up to polish to be processed.
As shown in Figure 1, described fixedly swing seat 5 comprises fixedly swing seat 501, lower fixedly swing seat 502, and upper fixedly swing seat 501 and lower fixedly swing seat 502 bolts link together.
It is 2 or 3 that pressure is adjusted handle 3, can facilitate rotation pressure to adjust handle 3.
