Abstract
The invention provides a clamp for assembly of a piston and an oil gun barrel. The clamp is a tubular body. A connecting part is arranged at one end of the tubular body. A guide part is arranged at the other portions of the tubular body. The internal diameter of the connecting part is slightly larger than the external diameter of the oil gun barrel. The inner wall of the guide part is conical. The end, close to the connecting part, of the guide part is a small end, and the internal diameter of the small end is slightly smaller than that of the oil gun barrel. The problems that installation is complex and labor hours are long in the assembling process of the piston and the oil gun barrel are solved, and the clamp for assembly of the piston and the oil gun barrel can greatly shorten assembly time, and is simple in structure and low in cost.
Description
Technical field
The present invention relates to a kind of assembling jig, relate to a kind of piston and oil barrel clamp for assembling specifically.
Background technology
In the process of assembly lube gun barrel and piston; because the piston ring on piston is only overlap also not shrink on the piston body; therefore the external diameter of piston ring is greater than the internal diameter of oil barrel; need during assembling first to make piston ring shrink and then install; usual piston body all overlaps and has multiple piston ring; therefore complex installation process, makes extend man-hour.
Summary of the invention
The object of this invention is to provide a kind of piston and oil barrel clamp for assembling, it can shorten installation time greatly, and structure is simple, cost is low.
To achieve these goals, technical solution of the present invention is: a kind of piston and oil barrel clamp for assembling, described fixture is tubular body, one end of tubular body is connecting portion, the remainder of tubular body is guide part, and the internal diameter of connecting portion is slightly larger than the external diameter of oil barrel, and the inwall of guide part is taper, one end of close connecting portion is small end, and the internal diameter of small end is slightly less than the internal diameter of oil barrel.
Inventive piston and oil barrel clamp for assembling, wherein, the tube wall of described tubular body has the breach extended vertically, the length of breach is equal with the length of tubular body.
After adopting such scheme, because the inwall of the tubular body guide part of inventive piston and oil barrel clamp for assembling is taper, one end of close connecting portion is small end, therefore first can be inserted in guide part by piston body during assembling, and promote inwards, in pushing course, piston ring shrinks gradually, when piston body is near oil barrel inwall, piston ring is contracted to and is slightly less than oil barrel internal diameter, makes assembling simpler, convenient, shortens installation time, and fixture is a tubular body, and structure is simple, cost is low.

Fig. 1 is the front sectional view of inventive piston and oil barrel clamp for assembling;
Fig. 2 be inventive piston and oil barrel clamp for assembling overlook partial sectional view;
Fig. 3 is the using state figure of inventive piston and oil barrel clamp for assembling;
Fig. 4 is oil barrel after assembling and the structure chart of piston.
Detailed description of the invention
As shown in Figure 1, 2, inventive piston and oil barrel clamp for assembling, this fixture is tubular body 11, one end of tubular body 11 is connecting portion 12, and the remainder of tubular body 11 is guide part 13, and the internal diameter of connecting portion 12 is slightly larger than the external diameter of oil barrel, connecting portion 12 can be enclosed within oil barrel, the inwall of guide part 13 is taper, and be small end near one end of connecting portion 12, the internal diameter of small end is slightly less than the internal diameter of oil barrel.
As Fig. 3, shown in 4, during use, the connecting portion 12 of tubular body 11 is enclosed within oil barrel 21, the piston body 221 of piston 22 is inserted in the guide part 13 of tubular body 11, in the process promoting piston 22 inwards, piston ring 222 on piston body 221 shrinks gradually, when piston body 221 from the small end of guide part 13 through later, piston ring 222 has been contracted to and has been slightly less than oil barrel 21 internal diameter, promote piston again, then piston body 221 enters in oil barrel 21 smoothly, easy for installation, after piston 22 is in place, take off tubular body 11, carry out other assembling again, oil barrel after assembling and piston are as shown in Figure 4.
For ease of fixture dismounting, the tube wall of tubular body 11 has the breach 111 extended vertically, the length of breach 111 is equal with the length of tubular body 11.
The above embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that the common engineers and technicians in this area make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determine.
