Abstract
The utility model provides a kind of piston and oil barrel clamp for assembling, can easily carry out the assembly of piston Yu oil suction gun barrel by the fixture, to reduce cost of labor, reduces and is lost, greatly improve production efficiency.The fixture is the guide sleeve with axial gap, the inner surface of guide sleeve includes the tapered surface section that cylindroid section and small end are connected with cylindroid section, and the internal diameter of cylindroid section is consistent with the outer diameter of oil barrel, the internal diameter of tapered surface section small end is consistent with piston body diameter, respectively less than the internal diameter of oil barrel；The piston ring being arranged in piston body outer circumference surface annular groove is the ring structure with opening, is installed in the annular groove of piston body outer circumference surface；After piston body protrudes into guide sleeve inside from the big end of guide sleeve tapered surface section, the opening of piston ring is gradually tapered up by tapered surface, to be allowed to be dimensioned slightly smaller than oil barrel internal diameter, and then so that piston body is pierced by guide sleeve and be smoothly fitted into oil barrel.
Description
Technical field
The utility model relates to a kind of fixture, in particular to a kind of piston and oil barrel clamp for assembling.
Background technique
Structure after oil barrel and piston assembly needs for piston rod to be connected with the one of piston body as shown in Fig. 2, when assembling
Hold coaxial package inside oil barrel, due between the piston ring and oil barrel that are arranged in piston body outer circumference surface annular groove
It is difficult for piston body to be smoothly packed into oil barrel in assembly for interference fit, it usually needs two people are coupled, and fill
With low efficiency, it is easily damaged piston.
Summary of the invention
In view of this, the present invention provides a kind of pistons and oil barrel clamp for assembling, can be facilitated by the fixture
The assembly of progress piston and oil suction gun barrel reduce and be lost, greatly improve production efficiency to reduce cost of labor.
The piston includes piston rod and the coaxially connected piston body in piston rod one end, the outer circumference surface of the piston body
On be machined with more than one annular groove coaxial with the piston body, a piston ring is placed in each annular groove；The piston
Ring and the oil barrel are interference fitted；
The fixture is the guide sleeve with axial gap, the inner surface of the guide sleeve include cylindroid section and small end with
The connected tapered surface section of the cylindroid section, and the internal diameter of the cylindroid section is consistent with the outer diameter of the oil barrel, the cone
The internal diameter of shape face section small end is consistent with the piston body diameter, the internal diameter of the respectively less than described oil barrel；
The piston ring is the ring structure with opening, is installed in the annular groove of the piston body outer circumference surface；When
After the piston body protrudes into guide sleeve inside from the big end of the guide sleeve tapered surface section, the piston is made by the tapered surface
The opening of ring gradually tapers up.
The utility model has the advantages that
By guide sleeve taper make piston rod be welded on piston ring (opening) gradually taper up, to be allowed to be dimensioned slightly smaller than oil
Gun barrel internal diameter, and then it is fitted into piston body integrally smoothly in oil barrel.It processes on guide sleeve simultaneously jagged, completes to fill
After matching, convenient for being removed from piston rod.The use of the fixture, reduces cost of labor, reduces loss, saves human resources,
Substantially increase production efficiency.
Detailed description of the invention
The connection schematic diagram that Fig. 1 is welded to piston rod for the fixture using the utility model and oil suction gun barrel is assembled；
Fig. 2 is that piston rod is welded and the structural schematic diagram after the assembly of oil suction gun barrel；
Fig. 3 is the structural schematic diagram of piston ring；
Fig. 4 is the structural scheme of mechanism of guide sleeve.
Wherein: 1- oil barrel, 2- guide sleeve, 3- piston rod, 4- piston ring, 5- pump nozzle, 6- piston body, 7- handle
Specific embodiment
With reference to the accompanying drawings and examples, the utility model is described in detail.
The present embodiment provides a kind of pistons and oil barrel clamp for assembling, for realizing the smooth dress of piston and oil barrel
Match.
As depicted in figs. 1 and 2, oil barrel 1 is hollow tubular construction, and one end coaxial welding has pump nozzle 5；Piston packet
It includes piston rod 3 and by the coaxially connected piston body 6 in 3 one end of piston rod of nut, the other end of piston rod is provided with handle 9.
There are three the annular groove coaxial with piston body 6, each annular groove is interior to place a piston ring for processing on the outer circumference surface of piston body 6
4, the structure of piston ring 4 clamps as shown in figure 3, for the ring structure with gap in a ring groove, due to piston ring 4 and mistake
Addiction cooperation, 4 outer diameter of piston ring is slightly larger than 6 outer diameter of piston body at this time.
The fixture is guide sleeve 2 shown in Fig. 4, and guide sleeve 2 is tool hollow tubular construction jaggy, that is, is led
There is axial gap to set 2, radial section is to have ring structure jaggy.The inner surface of guide sleeve 2 includes cylindroid section
The tapered surface section being connected with small end with the cylindroid section, and the diameter of tapered surface section small end is less than cylindrical portion diameter, thus in column
The junction of shape face section and tapered surface section forms step.2 inner surface of guide sleeve is the internal diameter of cylindroid section and the outer diameter of oil barrel
Unanimously, the internal diameter of tapered surface section small end is consistent with 6 diameter of piston body, is slightly less than the internal diameter of oil barrel.
When being assembled using guide sleeve 2 to piston and oil barrel, the opposite end of 1 pump nozzle of oil barrel, 5 connecting pin is coaxial
It is set in one end that 2 inner surface of guide sleeve is cylindroid section, and the end of oil barrel 1 contradicts the step surface inside guide sleeve 2
On；End where the piston body of piston is protruded into inside guide sleeve 2 from the big end of tapered surface section, passes through the taper of guide sleeve tapered surface section
Piston body upper piston ring (opening) is gradually tapered up, to be allowed to be dimensioned slightly smaller than oil barrel internal diameter, and then wears piston body
Guide sleeve is smoothly fitted into oil barrel 1 out, until piston rod is welded, the piston body 6 of end and the pump nozzle 5 of 1 end of oil barrel are supported
Touching.It after piston body 6 is fitted into oil barrel 1, since piston ring 4 is no longer pressurized, gradually opens, to be interference fitted with oil barrel 1.
Since guide sleeve 2 is set on piston rod in use, it is provided with notch, after completing assembly,
It can easily be removed from piston rod.Coming into operation for the fixture guide sleeve, reduces cost of labor, reduces loss, section
About human resources substantially increase production efficiency.
To sum up, the above is only the preferred embodiments of the present utility model only, is not intended to limit the protection of the utility model
Range.Within the spirit and principle of the utility model, any modification, equivalent replacement, improvement and so on should be included in
Within the protection scope of the utility model.
