Abstract
The utility model relates to a mounting machine, particularly a bearing push mounting machine piston cylinder, and comprises a cylinder body, a piston rod and a piston, wherein, the piston rod is fixedly connected with the piston to form a whole; the piston rod and the piston are arranged in the cylinder body and connected with the cylinder body in a sliding manner; and a hole is formed in the piston rod. The piston cylinder further comprises a mandrel and a travel switch, wherein, a spring is mounted at the tail part of the mandrel, a jacket is mounted at the front part thereof; the mandrel is arranged in the hole of the piston rod; an adjusting nut is sleeved on the middle part of the mandrel and the front end of the piston rod; and the travel switch is arranged on the jacket. The piston cylinder has the advantages of simple and practical structure, and convenient operation. Therefore, the piston cylinder can press mounting not only bearings, but also oil seals, thereby simplifying hydraulic system to save money and improve efficiency.
Description
Technical field:
The utility model relates to a kind of installation machinery, specifically a kind of Piston crock of bearing push mounting machine.
Background technique:
Traditional bearing press effect is single, can only pressing bearing, and efficient is lower, has influenced the whole production progress.Because the required pressure assembling force of installation of oil sealing and bearing differs greatly, and directly adopts original hydraulic system to damage oil seal by pressure too greatly because of extruding force.
Summary of the invention:
Goal of the invention of the present utility model is to overcome the prior art deficiency, and a kind of Piston crock of bearing push mounting machine that can pressing bearing can press-fit oil sealing again is provided.
The purpose of this utility model is finished by the following technical solutions:
A kind of Piston crock of bearing push mounting machine, comprise cylinder body, piston rod, piston, piston rod and piston fix as one, and place cylinder interior, be slidingly connected with cylinder body, be provided with porosely in the described piston rod, also comprise axle and position limit switch, the afterbody of described axle is equipped with spring, chuck is equipped with in the front portion, this axle places the hole of piston rod, adjusts the front end that nut sleeve is connected to axle middle part and piston rod, and described chuck is provided with position limit switch.
Adopt technique scheme, compared with prior art, the utility model has the advantages that: this pressing machine is simple in structure, practical, easy to operate, can pressing bearing, can press-fit oil sealing again, and simplified hydraulic system, economize on the use of funds the efficient height.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment:
See Fig. 1, a kind of Piston crock of bearing push mounting machine is by axle 1, chuck 2, piston rod 4, piston 6, compositions such as cylinder body 7, position limit switch 8.Piston rod 4 fixes as one with piston 6, places cylinder body 7 inside, is slidingly connected with cylinder body 7.Be provided with porose 9 in the piston rod 4, axle 1 afterbody is equipped with spring 5, chuck 2 is equipped with in the front portion, axle 1 places the hole 9 of piston rod 4, adjust nut 3 and be socketed in the middle part of axle 1 and the front end of piston rod 4, the right side of chuck 2 is provided with position limit switch 8, and the trip switch 8 and the stroke distances of adjusting between the nut 3 are a.
See Fig. 1, working principle of the present utility model is:
Adjust nut 3 and can adjust the pretightening force (press-fiting the required power of oil sealing) of spring 5.When press-fiting oil sealing, axle 1 and chuck 2 touch oil sealing and during stop motion, piston rod 4 is being with adjustment nut 3 to continue motion, when moving to apart from a, and impact stroke switch 8, then piston 6 returns, and oil sealing press-fits and finishes.The power of passing to oil sealing by axle 1 equals the elastic force sum that initial tension of spring and decrement a produce.Because spring 5 rigidity are to select according to the pressure assembling force of oil sealing, and pretightening force can adjust, and returned by position limit switch 8 controls, so required pressure assembling force can guarantee to press-fit oil sealing the time.
When pressing bearing, position limit switch 8 and spring 5 are inoperative.Bearing press mounting power by piston rod 4, adjustment nut 3, chuck 2, axle 1, is passed to bearing by piston 6 again.
