Description
Technical field
The present invention relates to valve press-loading device technical fields, and in particular to a kind of valve pressing machine.
Background technology
Valve oil seal installation is the important step in valve press fitting, and valve oil seal is mounted on valve guide bushing and can effectively be prevented
Only fluid enters in exhaust pipe and causes the loss and pollution of fluid, and engine motor oil is avoided to enter combustion chamber.In installation valve
During oil sealing, it is necessary to assure valve oil seal combines closely with valve guide bushing and is press-fit into place, and otherwise still be easy to cause the possibility of oil leak.
Valve guide bushing when installing valve oil seal, is first kept vertical state, by valve by valve oil seal press-loading device of the prior art
After oil sealing is placed in the surface of valve guide bushing, valve oil seal is pressed on the valve oil seal conduit of lower section using press-loading device.
In the process, the alignment of valve oil seal and valve guide bushing relies solely on artificial observation realization, it is difficult to ensure that valve oil seal is led with valve
The accurate practical effect that inconsistent phenomenon easily occurs in place, influences after valve oil seal installation between pipe.
Invention content
The invention is intended to provide a kind of valve pressing machine, to ensure the accurate connection of valve oil seal and valve guide bushing, prevent
Dislocation.
In order to achieve the above objectives, basic technology scheme of the invention is as follows：A kind of valve pressing machine, including board, board
Column is equipped with, is rotatably connected to the shaft being arranged in parallel and locating shaft on column, shaft is connected with actuating unit, connects in shaft
Swing arm is connected to, sliding block is connected in swing arm, is rotatably connected to rocker on locating shaft, rocker is equipped with bar hole and is fixedly connected
Pawl, sliding block are slidably connected in bar hole, and ratchet is also fixedly connected on locating shaft, and pawl is stuck between the ratchet of ratchet；It is vertical
Slide bar is fixedly connected on column, conveyer frames are slidably connected on slide bar, conveyer frames include the water chestnut that multiple transverse directions are arranged in order distribution
Shape frame, diamond shape frame include four head and the tail sequentially hinged connecting rod, and four connecting rods close to each other are common between neighboring diamonds frame
Disk is hinged with, arc groove is equipped on disk, arc groove is located in the axial direction of locating shaft, and bullet is connected between adjacent discs
Spring；Transmission mechanism and the cam of rotation connection are additionally provided on board, between transmission mechanism and cam, between transmission mechanism and shaft
Equal belt connection, the side of disk are equipped with the sliding slot with cam engagement.
The principle and advantage of this programme be：During practical application, valve guide bushing is horizontally placed in the arc groove of disk, valve guide bushing
Multiple arcs slot is sequentially passed through, valve guide bushing can be limited, ensures the straight of valve guide bushing, in order to valve oil seal
Accurate installation, and valve oil seal is enclosed on locating shaft.When actuating unit drives shaft rotation, shaft passes through transmission mechanism band
Moving cam rotates, and cam is against during rotation on the sliding slot of disk side, and disk is made to be moved to locating shaft side,
Disk drives the connecting rod movement for being connected to two diamond shape framves on disk so that two adjacent diamond shapes during movement
The width of frame becomes larger, and neighboring diamonds frame is mutually drawn when moving so that multiple disks are able to one sidesway of locating shaft
It is dynamic, so that valve guide bushing be pushed and be sleeved on locating shaft, and valve oil seal is squeezed to the end for the valve guide bushing for being inserted to face
On, realize the Primary Location between valve guide bushing and valve oil seal.Meanwhile close to locating shaft disk slide into valve guide bushing with
At the connecting portion of valve oil seal, the connecting portion between valve guide bushing and valve oil seal is clasped and incited somebody to action by the arc groove of the disk
Connecting portion is temporarily fixed, and valve oil seal is prevented to be detached from from valve guide bushing.
The swing arm associated movement that will drive connection while shaft rotates, so as to the slide block movement for connecting swing arm, sliding block
It reciprocatingly slides in bar hole, since rocker is rotatably connected on locating shaft, sliding block shakes promotion during slip
Plate reciprocally swinging.The pawl being fixedly connected on rocker follows rocker to swing, and is detached from from ratchet, when pawl is swung back again,
It will be caught between the ratchet of ratchet, and push ratchet that the rotation of certain angle occurs.Due to being fixed between locating shaft and ratchet
Connection, thus the rotation that locating shaft will be driven and occurred by ratchet certain angle, the portion that valve oil seal is connect with valve guide bushing
Position follows locating shaft to rotate and rotate in arc groove, and the connecting portion between valve oil seal and valve guide bushing is by arc groove
The blocking of cell wall and be constantly aligned, the place that connecting portion misplaces is adjusted, so as to fulfill valve guide bushing and gas
Accurate connection between door oil sealing, avoids and misplaces therebetween, ensure the accurate installation of valve oil seal.
Preferably, as an improvement, cam, ratchet, pawl and conveyer frames are equipped with corresponding two groups, two groups of conveyer frames
It is distributed by axisymmetrical of slide bar, and two symmetrical close ends of diamond shape frame are hinged and hinge point is slided jointly
It is dynamic to be connected on slide bar.Two groups of conveyer frames and click can simultaneously assemble two groups of valve guide bushings and valve oil seal,
Improve the installation effectiveness of valve oil seal.
Preferably, as an improvement, baffle is equipped in the arc groove on the disk of cam.When disk slides,
Baffle is against on the end of valve guide bushing, valve guide bushing can be pushed to locating shaft side, is prevented valve guide bushing from being transported to disk
Dynamic negative direction is mobile and can not be transferred on locating shaft.
Preferably, as an improvement, friction protrusion is equipped in arc groove.Friction protrusion can increase arc groove and gas
Rubbing action between door conduit, so as to which valve guide bushing to be effectively pushed to the press fitting that valve oil seal is carried out on locating shaft.
Preferably, as an improvement, sliding rail is fixedly connected on column, disk is slidably connected on sliding rail.Sliding rail
The moving direction of disk can be oriented to, ensure the flat transmission of valve guide bushing, reduce valve guide bushing and valve oil seal it
Between the probability that misplaces.
Preferably, as an improvement, transmission mechanism includes the first bevel gear and the second bevel gear of engagement, the first umbrella tooth
Wheel is fixedly connected with transmission shaft, and belt connects between transmission shaft and shaft, and the second bevel gear is connect with cam belt.Shaft rotates
When, transmission shaft is driven to rotate by belt, transmission shaft drives the first bevel-gear rotating, the promotion of the first bevel gear engage the
Two bevel-gear rotatings so that power is transferred on cam and is rotated with moving cam by the second bevel gear, utilizes the energy in system
It realizes the control to cam, reduces energy consumption.
Preferably, as an improvement, locating shaft is equipped with stop collar.Stop collar can limit the position of valve oil seal,
When avoiding valve guide bushing contact valve oil seal, valve oil seal persistently slides on locating shaft and causes valve oil seal that can not be inserted to gas
On door conduit.
