Description
Technical field
The utility model is the maintenance unit of the automobile plunger displacement pump used of a kind of oil field, is a kind of supply-water pump cylinder sleeve handler.
Background technology
Cylinder sleeve on the supply-water pump used of oil field is because wearing and tearing need to change in time after long-term use, and the lubricant reservoir otherwise water under high pressure can bleed, makes deterioration of lubricant, causes device damage.Changing at present cylinder sleeve will carry out dismounting from the lubricant reservoir of plunger, compact conformation herein, and narrow space, dismounting is very difficult, assembly and disassembly methods can not guarantee dismounting quality, wastes time and energy, and labor strength is large, inefficiency, work quality is poor, is difficult to assure feed water pump and normally works.In order to address this problem, technical staff has made some instruments cylinder sleeve has been dismantled, although the cylinder sleeve of dismounting supply-water pump easily and efficiently, but it need to remove pump head to be installed on lathe and could implement after its left end processes internal thread, so not only have the workload of machining screw, also will increase the workload of dismounting pump head, labor strength is large, inefficiency, implements inconvenient.
Summary of the invention
The purpose of this utility model is a kind of supply-water pump cylinder sleeve handler of design, and the cylinder sleeve of dismounting supply-water pump, alleviates labor strength easily and efficiently, increases work efficiency.
The purpose of this utility model is achieved in that and comprises rotating shaft, clamping nut, righting axle core, pump head, cylinder sleeve, cylinder sleeve gland, transmission cover, gear cap, on righting axle core, be set with cylinder sleeve, make in the sleeve port of cylinder sleeve in pump head, the external screw thread of cylinder sleeve gland is connected with the internal thread of pump head right-hand member, the circular bead surface of cylinder sleeve is withstood in cylinder sleeve gland left side, on cylinder sleeve gland, there is protruding key, fluted on transmission cover, protruding key and groove interlock, rotating shaft is through righting axle core, transmission cover, rotating shaft right part surface is polygon and matches with the polygonal hole on transmission cover, make can not relatively to rotate between rotating shaft and transmission cover, the screw thread of rotating shaft right-hand member is threaded with gear cap, the screw thread of rotating shaft left end is threaded with clamping nut, between the right part of pump head and righting axle core, 2-3 piece slips is installed, on the outer wall of slips, there are teeth, the contact-making surface of righting axle core and slips is coned face, tapering is 4-6 °.
The beneficial effects of the utility model are: the contact-making surface of righting axle core and slips is coned face, and tapering is 4-6 °, be less than Self-locking angle, can produce self-locking, righting axle core and slips can be locked into one certainly, on the outer wall of slips, there are teeth, can embed in the stomidium of pump head, thereby righting axle core is maintained static, the left end machining screw that not be used in pump head when handling cylinder sleeve just can be implemented, the workload that there is no dismounting pump head and machining screw, can facilitate, the cylinder sleeve of dismounting supply-water pump efficiently, alleviate labor strength, increase work efficiency, not dismounting pump head can also improve repair quality, therefore, the utlity model has significant economic benefit.
Accompanying drawing explanation
Fig. 1 is the installation diagram of the utility model embodiment.
The specific embodiment
Below in conjunction with Fig. 1, the utility model embodiment is described.
As seen from the figure, embodiment of the present utility model comprises rotating shaft 1, clamping nut 2, righting axle core 3, slips 4, pump head 5, cylinder sleeve 6, cylinder sleeve gland 7, transmission cover 8, gear cap 9, on righting axle core 3, be set with cylinder sleeve 6, make in the sleeve port of cylinder sleeve 6 in pump head 5, the external screw thread of cylinder sleeve gland 7 is connected with the internal thread of pump head 5 right-hand members, the circular bead surface of cylinder sleeve 6 is withstood in cylinder sleeve gland 7 left sides, on cylinder sleeve gland 7, there is protruding key 10, on transmission cover 8 fluted 11, protruding key 10 interlocks with groove 11, make it can transmitting torque, rotating shaft 1 is through righting axle core 3, transmission cover 8, rotating shaft 1 right part surface is polygon and matches with the polygonal hole on transmission cover 8, make can not relatively to rotate between rotating shaft 1 and transmission cover 8, make it can transmitting torque, the screw thread of rotating shaft 1 right-hand member is threaded with gear cap 9, the screw thread of rotating shaft 1 left end is threaded with clamping nut 2, between the right part of pump head 5 and righting axle core 3,2-3 piece slips 4 is installed, on the outer wall of slips 4, there are teeth, righting axle core 3 is coned face with the contact-making surface of slips 4, tapering is 4-6 °, this angle is less than Self-locking angle, both can be locked into one.
On righting axle core 3, be set with cylinder sleeve 6, make cylinder sleeve 6 and sleeve port concentric, be convenient to cylinder sleeve 6 and pack sleeve port into, do not need manually to align, rotating shaft 1 can drive 7 rotations of cylinder sleeve gland, cylinder sleeve gland 7 can be quickly installed on pump head 5, also can fast cylinder sleeve 6 be pressed in sleeve port.
