Description
Technical field
The utility model crank guide acts specific purpose tool and belongs to oil recovery machiner area of maintenance.
Background technology
Oil pumping machine crank bearing pin is one of crucial rotary part that can oil pumper run well, and such as it can not reliably be operated
Easily cause all kinds of failures of oil pumper or even turn over the accident taken out.It is very important link in maintenance work to change crank guide,
Old guide is subject to corrosion viscous dead in crank internal surface of hole, acts narrow space, staff tap take out when, if pounded
To crank bounce-back, danger can be brought to operating personnel, if bushing unbalance stress causes deflection during percussion, can also extended when safeguarding
Between, need welding to take out if necessary, maintenance cost is increased again.
Utility model content
In order to solve the above problems, the utility model provides a kind of crank guide and acts specific purpose tool, and the instrument can
The disposable crank guide that completes acts operation, increased the security of operating personnel, has saved maintenance time and maintenance cost, and
When resume production.
What the purpose of this utility model was realized in：
A kind of crank guide acts specific purpose tool, including round platform baffle plate, fixed screw, limit spring, catch and impact bar；
Described round platform baffle plate is for circumference taper is identical with crank guide inner surface taper, be provided centrally with the circle of through hole A
Platform；
Described catch is diameter and crank guide external diameter identical cylinder, and the center of circle sets through hole B, at the 20mm of the center of circle
Through hole C is set, connectivity slot is provided between through hole B and through hole C, positioning circular groove is coaxially disposed with through hole B；
Described impact bar is divided into coupling part and impact part, and coupling part is the body of rod of diameter 15mm, impacts part
Be the body of rod of a diameter of 30mm, coupling part is fixedly connected with impact part, and the coupling part other end sets screw thread, can with it is solid
Determine screw cooperation, the impact part other end sets impact end；
Described limit spring is covered on the connection portion, between round platform baffle plate fixed screw.
Above-mentioned crank guide acts specific purpose tool, and through hole A internal diameters, through hole B internal diameters, connectivity slot groove width are more than 15mm, and
Less than 30mm, through hole C diameters and positioning circular groove are with diameter greater than 30mm.
Beneficial effect：The utility model crank guide rise specific purpose tool, the instrument using impact bar coupling part according to
The secondary screw that is connected, limit spring and round platform baffle plate, and in crank bushing, make in the circumference of round platform baffle plate and crank
Surface is fitted, and the impact of impact bar is partially passed through the through hole C of catch, and catch is placed on into liner rim, and tension makes impact bar
Coupling part can enter through hole B through connectivity slot, the impact part of impact bar snaps in the positioning circular groove of catch after release, limit
The tightening force of position spring enables round platform baffle plate, impact bar and catch to be fitted close, the impact end of hammer impacts bar, you can once
Property complete crank guide and act operation.
The utility model crank guide acts specific purpose tool, and simple structure is easy to operate, increased the safety of operating personnel
Property, maintenance time and maintenance cost have been saved, resume production in time.
Brief description of the drawings
Fig. 1 is the structural representation that the utility model crank guide acts specific purpose tool.
Fig. 2 is the structural representation that the utility model crank guide acts catch in specific purpose tool.
In figure：1 round platform baffle plate, 2 fixed screws, 3 limit springs, 4 catch, 5 impact bars, 51 coupling parts, 52 impact portions
Point.
Specific embodiment
The utility model specific embodiment is described in further detail below in conjunction with the accompanying drawings.
Specific embodiment one
The crank guide of the present embodiment rise specific purpose tool, structural representation as shown in figure 1, include include round platform baffle plate 1,
Fixed screw 2, limit spring 3, catch 4 and impact bar 5；
Described round platform baffle plate 1 is for circumference taper is identical with crank guide inner surface taper, be provided centrally with the circle of through hole A
Platform；
Described catch 4 is diameter and crank guide external diameter identical cylinder, and the center of circle sets through hole B, away from center of circle 20mm
Place sets through hole C, and connectivity slot is provided between through hole B and through hole C, and positioning circular groove is coaxially disposed with through hole B；
5 points described of impact bar is coupling part 51 and impact part 52, and coupling part 51 is the body of rod of diameter 15mm, punching
The body of rod that part 52 is a diameter of 30mm is hit, coupling part 51 is fixedly connected with impact part 52, and the other end of coupling part 51 sets
Screw thread is put, can be coordinated with fixed screw 2, the impact other end of part 52 sets impact end；
Described limit spring 3 is enclosed within coupling part 51, between the fixed screw 2 of round platform baffle plate 1.
The utility model crank guide acts specific purpose tool, and the instrument is sequentially connected fixation using the coupling part of impact bar
Screw, limit spring and round platform baffle plate, and in crank bushing, the circumference of round platform baffle plate is fitted with crank inner surface,
The impact of impact bar is partially passed through the through hole C of catch, catch is placed on liner rim, tense, make the connecting portion of impact bar
Dividing can enter through hole B through connectivity slot, and the impact part of impact bar snaps in the positioning circular groove of catch after release, limit spring
Tightening force enables round platform baffle plate, impact bar and catch to be fitted close, the impact end of hammer impacts bar, you can disposable to complete bent
Handle guide acts operation.
Specific embodiment two
The crank guide of the present embodiment acts specific purpose tool, on the basis of specific embodiment one, further limited hole A
Internal diameter, through hole B internal diameters, connectivity slot groove width are more than 15mm, and less than 30mm, through hole C diameters and positioning circular groove are with diameter greater than 30mm.
This is designed to enable round platform baffle plate, impact bar and catch to be fitted close, it is ensured that the validity of instrument.
