Description
Technical field
The present invention relates to a kind of mechanical extracting tool, in particular to a kind of fluid coupling draw bench special.
Background technology
Because producing or maintenance purpose, need to take drawing means to dismantle some equipment, such as fluid coupling, or the leading screw displacement utilizing rotating threaded shaft to produce, fluid coupling is shirked mutually with reductor high speed shaft.The shortcoming of above-mentioned technology is: take drawing means to dismantle effect undesirable, and easy damage equipment, and the mode taking leading screw to rotate needs the frictional force overcoming screw thread pair generation, and screw head and reductor high speed shaft are removed and relatively rotated the frictional force produced.Because fluid coupling and reductor high speed shaft are interference fit, need very large axial force when making it be separated, this axial force makes screw thread pair rotate and produces great frictional force, and leading screw must overcome this frictional force and could rotate, and therefore operational effectiveness is low.
Summary of the invention
The technical problem to be solved in the present invention is to provide one and alleviates operative employee's labour intensity, improves the fluid coupling draw bench special of operational effectiveness.
The technical solution adopted for the present invention to solve the technical problems is: comprise and draw horse base plate, adjusting screw, draw head of the horse portion, adjusting screw two ends respectively with draw horse base plate and draw head of the horse portion to form to be fixedly connected with, head of the horse portion is drawn to comprise head base, be fixedly connected with head base one with externally threaded column, head base and column are run through in head center hole.
After adopting said structure, its feature is: by means of conventional jack and common round steel, first the column drawing head of the horse portion to be threaded part is screwed in the screw thread of fluid coupling central shaft, in order adjusting screw, round steel, draw horse base plate, hydraulic jack is seated, utilize artificial less strength, starting jack makes jack spindle nose stretch out, round steel is utilized to conduct the strength of jack, overcome the frictional force produced when fluid coupling axle is separated with reductor high speed shaft, fluid coupling is just split to get off.
Preferably, adjusting screw two ends respectively by screwed hole with draw horse head base and draw horse base thread to be connected, draw horse head base and draw horse base plate respectively with adjusting screw nut pretension, to be carried on the axial load overcoming frictional force when fluid coupling is separated with reductor high speed shaft and produce, avoid producing displacement or slip when drawing horse stand under load.
Preferably, draw head of the horse portion to comprise the deep floor be fixedly connected with it, strengthen the impact strength of drawing head of the horse portion.
Compared with prior art, the invention has the beneficial effects as follows: the present invention reduces labor intensity, by jack, just fluid coupling can be separated from reductor high speed shaft by less power, improve production efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the top view drawing head of the horse portion in Fig. 1;
Fig. 3 is the structural representation that the present invention dismantles fluid coupling when coordinating with jack, round steel.
Be labeled as in figure:
1, draw horse base plate 2, draw head of the horse portion 21, draw horse head base 22, deep floor 23, column 24, head center hole 25, screwed hole 3, adjusting screw 4, jack 5, round steel 6, fluid coupling 7, reductor high speed shaft 8, nut.
It is pointed out that Reference numeral identical in figure represents same or analogous device or parts.
Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the present invention is described further:
Fluid coupling draw bench special as shown in Figure 1, comprise and draw horse base plate 1, draw head of the horse portion 2, with head base 21 be fixed with one with externally threaded column 23, and head base 21 and column 23 are run through in head center hole 24, head center hole 24 allows the round steel 5 of pushing tow reductor high speed shaft 7 to pass through when dismantling, this draws horse base plate 1 and draws the size in head of the horse portion 2 suitably to adjust according to the large I of the base of jack 4, adjusting screw 3 can select two ends with externally threaded leading screw, adjusting screw 3 two ends respectively with draw horse base plate 1 and draw horse head base 21 to form to be fixedly connected with, be suitable for mutually with the height of jack 4 when dismantling to meet.
Fig. 2 shows and draws the top view of head of the horse portion 2 when Fig. 1 position, column 23 external screw thread and the fluid coupling 6 central shaft screw that will dismantle match, the deep floor 22 drawing head of the horse portion 2 also to comprise to be fixedly connected with it, draws the impact strength of head of the horse portion 2 in unloading process to strengthen.Adjusting screw 3 two ends by draw horse base plate 1 and draw in head of the horse portion 2 arrange screwed hole 25 respectively with draw head of the horse portion 2 and draw horse base plate 1 to be threaded, draw horse head base 21 and draw horse base plate 1 fastening in advance with adjusting screw 3 nut 8 respectively, strengthen the reliability and compactness that connect, prevent from, in unloading process, Relative sliding occurs.
The course of work of the present invention is as follows:
As shown in Figure 3, first drawing the threaded column 23 in head of the horse portion 2 to screw in inside the screw thread of fluid coupling 6 central shaft, round steel 5 imports in the central shaft screw of fluid coupling 6 along drawing head of the horse portion centre bore 24, successively by adjusting screw 3, draw horse base plate 1, jack 4 is in place, nut 8 can be used adjusting screw 3 and draw horse base plate 1 and draw head of the horse portion 2 fastening in advance, start jack 4, round steel 5 is utilized to transmit the service load of jack 4, round steel 5 continuous extrusion reductor high speed shaft 7, when the service load of jack 4 can overcome the frictional force produced when fluid coupling 6 is separated with reductor high speed shaft 7, fluid coupling will slowly be removed.
So, compared with traditional dismounting mode, the present invention can greatly increase work efficiency, and operative employee just can produce larger service load by less power by small-sized common hydraulic jack, and use simple, mounting or dismounting are convenient.
The above is only preferred embodiment of the present invention, and be not restriction the present invention being made to other form, any those skilled in the art may utilize the technology contents of above-mentioned announcement to be changed or be modified as the Equivalent embodiments of equivalent variations.But everyly do not depart from technical solution of the present invention content, any simple modification, equivalent variations and the remodeling done above embodiment according to technical spirit of the present invention, still belong to the protection domain of technical solution of the present invention.
