As shown in figure 1, according to the concrete of the disassembling fixture of the engine valve lock clamp of the utility model specific embodiment
Structure includes：Switching regulator magnet base 1, guide pillar 2, gripper shoe 3, nut 4, capstan handle thread spindle 5, work briquetting 6 and work
Pressing plate 7.Wherein, two switching regulator magnet bases 1 are individually positioned in the air inlet side and exhaust side of cylinder cap, for the machine to be keeped in repair
Type feature, the locking nut 4 on appropriate adjustment guide pillar 2 makes distance between two guide pillars 2 suitable, the circular cone in the middle of the pressing plate 7 that works
After hole is placed on the cotter seat for be dismantled valve collet, by the switch rotary on switching regulator magnet base 1 to adhesive
State, now first with hand by the pre-screwing of capstan handle thread spindle 5, then can twist capstan handle thread spindle 5 by instrument, make work
Briquetting 6 is moved down under pressure, and then the pressing plate 7 that pushes the work forward downwards shrinks valve spring extruding, treats valve collet
After completely out cotter seat, failure valve collet is taken out with hand, change new valve collet, then the capstan handle that comes up
Thread spindle 5, that is, complete changeing for valve collet,
Specifically, as shown in Figures 2 and 3, the quantity of switching regulator magnet base 1 is two, for being pull-in on cylinder respectively
The air inlet side and exhaust side of lid, the magnet base top surface central authorities of the switching regulator magnet base 1 offer guide pillar screwed hole, for solid
Determine guide pillar 2.
Guide pillar 2 is that, with externally threaded screw rod, its quantity is and corresponding two of switching regulator magnet base 1 to pass through respectively
Its one end is screwed into the screwed hole of switching regulator magnet base top surface and is vertically arranged, and the mainly operation to the pressing plate 7 that works play the guiding role.
As shown in figure 4, gripper shoe 3 is rectangle steel plate, one end of gripper shoe 3 processes an energy and leads to through the first of guide pillar
Hole, the middle part of gripper shoe 3 processes a thread spindle screw that can be screwed into capstan handle thread spindle 5, and the other end is processed one and can be worn
The first U-lag of guide pillar is crossed, the position of side switching regulator magnet base 1 and guide pillar 2 is conveniently adjusted, the fortune of different type of machines is realized
With.After the type to be keeped in repair determines, two nuts 4 are first screwed on guide pillar 2, then gripper shoe 3 are installed on guide pillar 2,
By adjusting the following two nut of gripper shoe 3, the holding level of gripper shoe 3 and certain altitude are made, after being adjusted in place, then in guide pillar 2
On be screwed into two nuts 4, fix gripper shoe 3.
As shown in Figure 5 and Figure 6, capstan handle thread spindle 5 includes：Screw shaft and it is separately positioned on the screw shaft two ends
Capstan handle and spinning ball.Capstan handle includes：Spheroid and the capstan handle of the spheroid the week side of boss is welded on, capstan handle
A spherula is all welded in end, and cross handle is convenient with hand operation and tubing instrument application.Spinning ball is used for and work
The spherical interporal lacuna of the top semi-circular of briquetting 6 coordinates.
As shown in Figure 7 and Figure 8, the briquetting 6 that works is made using a block length cube nylon block, and its basal surface position processes semicircle
The slot to make way of bridge opening shape, top surface processes a semicircle spherical pore, between the spinning ball formation for capstan handle thread spindle 5
Gap ball-and-socket coordinates, and butter lubrication is added between the two, to reduce the abrasion of the briquetting 6 that works nylon.The diameter of semicircle spherical pore
1-1.5mm bigger than the diameter of the spinning ball of capstan handle thread spindle 5 or so.
As shown in Figure 9 and Figure 10, the pressing plate 7 that works is made using a block length cube nylon block, one end processing of the pressing plate 7 that works
Through the second through hole of guide pillar, centre processes a trapezoidal conical bore, trapezoidal circular cone bore dia little one side during installation to one energy
Down, the other end of work pressing plate 7 processes second U-lag that may pass through guide pillar, conveniently adjusts the side switching regulator magnet bottom
The position of seat 1 and guide pillar 2, realizes utilization of this disassembling fixture in different type of machines.Use suitable between work pressing plate 7 and work briquetting 6
Amount glue connection, it is convenient that associated components are changed at any time according to abrasion or damaged condition.
The course of work is：This disassembling fixture is placed on into cylinder cap top, two switching regulator magnet bases 1 are individually positioned in cylinder
The air inlet side and exhaust side of lid, for the Machine structural features to be keeped in repair, the locking nut 4 on appropriate adjustment guide pillar 2, makes two to lead
Distance is suitable between post 2, and the round taper hole in the middle of the pressing plate 7 that works is placed on the cotter seat to be dismantled valve collet
Afterwards, by the switch rotary on switching regulator magnet base 1 to attracting state, now can be first pre- by capstan handle thread spindle 5 with hand
Tighten, then capstan handle thread spindle 5 is twisted by instrument, work briquetting 6 is moved down under pressure, and then push the work forward
Pressing plate 7 downwards shrinks valve spring extruding, after the completely out cotter seat of valve collet, with hand failure valve lock is taken out
Folder, changes new valve collet, then the capstan handle thread spindle 5 that comes up, that is, complete changeing for valve collet, such as to tear open
Other valve collets are changed, then need to only unclamp the switch on capstan handle thread spindle 5, then moving switch type magnet base 1 is to suitable
Position, with same method the dismantlement work of other valve collets is completed.
To sum up, the disassembling fixture of the engine valve lock clamp facilitates maintenance personal arbitrarily to adjust suction of the base in top surface of cylinder cover
Position is closed, can be used for the maintenance of different engines (Cast Iron Cylinder Head) valve collet；And this frock need not borrow cylinder bolt
And the cylinder bolt hole on body, quality impact is not resulted on cylinder bolt, body；And intermediate pressing block and work briquetting are adopted
With nylon material, nylon material can reduce frock total quality, and it is little that maintenance personal moves physical demands.
The aforementioned description to specific illustrative embodiment of the present utility model be in order to illustrate and illustration purpose.These
Description is not wishing to for the utility model to be defined to disclosed precise forms, and it will be apparent that according to above-mentioned teaching, can carry out
It is many to change and change.The purpose of selecting and describing the exemplary embodiment is that explaining certain principles of the present utility model
And its practical application, so that those skilled in the art can realize and using a variety of examples of the present utility model
Property embodiment and a variety of selections and change.Scope of the present utility model is intended to by claims and its waits similar shape
Formula is limited.
