Abstract
The invention discloses a valve grinding device capable of performing positioning. The valve grinding device comprises a motor, a chuck and a handheld sleeve are sequentially connected below the motor, a grinding disk and a pressing plate are sequentially connected below the handheld sleeve, a pressure adjusting device located above the grinding disk is further connected to the handheld sleeve, the pressure adjusting device comprises a pressure adjusting handle, the pressure adjusting handle is installed on a pressure adjusting rotating cover, an adjustable support is connected below the pressure adjusting rotating cover, and the adjustable support is fixed to a fixing swing base through a bolt. The pressure adjusting device is arranged on an existing valve grinding device capable of performing positioning, acting force applied to the grinding disk can be adjusted through the pressure adjusting handle, the acting force on the grinding disk can be prevented from being too large to too small, and therefore the valve grinding device is more favorable for grinding work and convenient and fast to use.
Description
Technical field
The present invention relates to orientable valve grinding device, be specifically related to a kind of fine-tuning valve grinding device in many ways using 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 valve grinding device, when grinding valve seat, can not accurately be located the degree of depth of grinding, and just according to reckoning, carries out the grinding of valve seat, easily causes excessive grinding or grinds inadequate problem.
Summary of the invention
The invention provides orientable valve grinding device, can solve the degree of depth that grind accurate location, reach the object of better grinding valve.
Object of the present invention reaches by the following technical programs:
Orientable valve grinding device, 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 locating piece that is positioned at abrasive disk top, and described pressure locating piece comprises with adjustable support and be arranged on the handle on adjustable support, and pointer is carved with on adjustable support top, the bottom of adjustable support is provided with scale, and adjustable support is bolted on fixing swing seat.On lapping device, be provided with pressure locating piece, can apply to abrasive disk on the one hand the active force of compression, impel abrasive disk to contact with to be processed and be well convenient to processing, the effect of also playing on the other hand location can allow abrasive disk aim at the face that needs processing while making to grind, what guarantee to grind carries out smoothly.In adjustable support, be also provided with rolling bearing, can reduce friction.
Scale and pointer are set on adjustable support, be conducive to the degree of depth of accurately knowing that abrasive disk feeds, can before also grinding base not being installed, first grind the pre-estimation of the degree of depth, hand-held cover is slowly contacted down to abrasive disk and face to be processed, rotary handle regulates pressure locating piece again, according to the grinding degree of depth of pre-estimation, according to the scale on adjustable support, deduct about 0.5mm, be rotated the distance that regulates abrasive disk and to be processed.With this, avoid briquetting and to be processed 's distance too approaching, and also to briquetting, apply certain pressure in the pressure locating piece of rotation, can guarantee that like this briquetting can suitably contact and can guarantee that briquetting and to be processed 's pressure is suitable with to be processed, is unlikely to damage to be processed and briquetting.
Described fixing swing seat comprises fixing swing seat, intermediate connector, lower fixing swing seat, and upper fixing swing seat and lower fixing swing seat link together by intermediate connector bolt.
Described intermediate connector is the two sections of separate type, and these two sections arrange external screw thread, hypomere by epimere and internal thread is set connects.The setting of the intermediate connector of fixing swing seat is the valve that is more suitable for different model, the valve of different model, the degree of depth that is positioned at valve of nature valve seat is inconsistent, be cost-saving raising the efficiency like this, in the time need to carrying out attrition process to the valve of other models, only the bottom of intermediate connector need to be withdrawn together with lower swing seat, when particularly swing seat or intermediate connector damage instantly, only need a replacing part wherein can guarantee the regeneration use of whole device.
Described abrasive disk is connected with hand-held cover bolt.
Described adjustable support is provided with fixed support plate adjustable support is arranged on fixing swing seat, is also provided with rolling bearing in adjustable support, can reduce friction.
The present invention compared with prior art, there is following advantage and beneficial effect:
The present invention on existing orientable valve grinding device, be provided with one can the hand-held cover of accurate adjustment press down the degree of depth can graduated pressure locating piece, can adjust handle by pressure locating piece and regulate the distance that is applied to active force on abrasive disk and rotating scale and adjusts abrasive disk and to be processed, can guarantee that briquetting can suitably contact and can guarantee that briquetting and to be processed 's pressure is suitable with to be processed, is unlikely to damage to be processed and briquetting.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
