Technical field
The invention belongs to spray equipment technical fields, and in particular to a kind of spray equipment for planar valve seat.
Background technique
In order to improve the anticorrosion antiwear performance for the valve base surface that petrochemical industry uses, usually in two planes of valve seat
The alloy or alloy carbide coating that upper spraying a layer thickness is 0.1 ~ 0.5mm or so, the valve seat of gate valve is ring-shaped work pieces, sees figure
1.Under normal conditions, in the coating for preparing valve base surface, all it is to fix valve seat vertically, then, is sprayed using supersonic flame
The a wide range of horizontal reciprocating movement of rifle, to realize the spraying to valve base surface.Due to there is a macropore among valve base surface,
Most of powder all do not deposit to valve seat up, cause very big waste, are badly in need of tooling and work to conventional spray paint valve seat
Skill improves.
Summary of the invention
It is a kind of for plane technical problem to be solved by the present invention lies in view of the above shortcomings of the prior art, providing
The spray equipment of valve seat.Valve seat of the invention is clamped by scroll chuck and is made high speed rotation, and spray gun only needs the position according to valve seat
It sets and moves horizontally and moving back and forth up and down by a small margin, so that it may spray uniform coating on valve seat, this makes the overwhelming majority
Powder all deposits on valve seat, and sprayed on material, the energy and spraying time is greatly saved.
In order to solve the above technical problems, the technical solution adopted by the present invention is that: a kind of spray equipment for planar valve seat,
It is characterized in that, the spray equipment has the feature that
A kind of spray equipment for planar valve seat, including bracket, speed regulating motor, drive sprocket, main shaft, driven sprocket, bearing
Seat, chain, scroll chuck and spray gun, the main shaft pass through bearing block, and the front end of main shaft is connected with scroll chuck, and rear end is provided with
Driven sprocket, bearing block is rack-mount, and one end of bracket is provided with speed regulating motor, is equipped with drive chain on speed regulating motor
Wheel, spray gun are fixed on the movable fixture apart from valve seat surface 150-450mm to be sprayed, and when speed regulating motor rotates, valve seat exists
Spray gun alternately pumps and intermittent horizontal movement while rotation under the drive of main shaft.
The drive sprocket is by chain drive driven sprocket, and then driving spindle drives the valve seat on scroll chuck to make together
Walk high speed rotation.
The valve seat reversely supports the front end for being fixed on main shaft by the interior claw of scroll chuck outside.
The drive sprocket is connect by motor shaft with speed regulating motor.
The bearing block, which is embarked on journey, to be symmetrically fixed on bracket, is provided with main shaft on each bearing block.
The scroll chuck is connect by main shaft with driven sprocket.
The chain is closed chain, driven sprocket is bypassed in a manner of alternate up and down, finally and on speed regulating motor
Drive sprocket connection.
The middle position of neighbouring valve seat is arranged in the spray gun, and intermittent level is done under the drive of movable fixture
Mobile, when the middle position of neighbouring valve seat is arrived in spray gun horizontal movement, spray gun stops moving horizontally, and changes and does by a small margin
It moves back and forth up and down.
The movable fixture is two-dimentional machinery hand.
Compared with the prior art, the present invention has the following advantages:
(1) valve seat is clamped by scroll chuck and is made high speed rotation, by spray gun intermittent horizontal movement and pumps
Alternately, being sprayed on coating uniform on valve seat, most coating can deposit on valve seat, compensate for existing
There are most of powder depositions in technology that sprayed on material, the energy and spraying time is greatly saved less than the deficiency on valve seat.
(2) high-speed rotating valve seat in air can cooling faster, no longer need to it is cooling using additional compressed air,
The claw of scroll chuck can be movable in a big way, and the size range for the valve seat that can be gripped is wide, increases the dress
The applicability set.
(3) enclosed chain bypasses driven sprocket in upper and lower alternation method, can increase chain to the cornerite of sprocket wheel, increase
The reliability being driven by force.
Technical solution of the present invention is described in further detail below by the drawings and specific embodiments.
