The retainer ring for the hole is mainly used for being arranged in an inner hole of a workpiece and used for fixing the axial movement of a part, and the outer diameter of the retainer ring is slightly larger than the diameter of the round hole for assembly. The traditional retainer ring for holes adopts clamp spring pliers, a clamp mouth is inserted into a clamp hole of the retainer ring, the retainer ring is compressed in a clamping mode, the outer diameter of the retainer ring is reduced, the retainer ring is placed into a round hole inner groove machined in the side wall of an inner hole of a workpiece, the clamp spring pliers are loosened, the retainer ring is expanded and clamped into the round hole inner groove, the clamp spring pliers are required to be manually operated in the installation mode, the installation operation is relatively time-consuming and labor-consuming, and especially for some narrow parts or space inner holes with smaller apertures, the installation of the retainer ring is difficult to be completed in the assembly mode operation of the clamp spring pliers.
Disclosure of utility model
In view of the shortcomings of the background art, the technical problem to be solved by the utility model is to provide a narrow hole retainer ring assembly tool for solving the problems.
For this purpose, the utility model is realized by adopting the following scheme:
Narrow type hole is with retaining ring assembly fixture, its characterized in that: the device comprises a sleeve, wherein a push rod is movably arranged in the sleeve, the push rod is connected with a movable driving assembly, one end of the sleeve is provided with a retaining ring sleeve, an inner ring of the retaining ring sleeve can be used for clamping a compressed retaining ring, the aperture of the inner ring of the retaining ring sleeve is smaller than the aperture of an inner hole of a retaining ring to be installed on a workpiece, and the push rod can push the compressed retaining ring in the retaining ring sleeve into a retaining ring installation groove of the inner hole of the retaining ring to be installed on the workpiece.
The movable driving assembly comprises an air cylinder, and a piston rod of the air cylinder is connected with the ejector rod.
And the check ring sleeve is in threaded connection with the sleeve.
The sleeve is fixedly arranged on the mounting frame, and the mounting frame is fixedly connected with the base.
The cylinder body of cylinder sets up on the base, the cylinder is located the below of sleeve.
The assembly fixture for the retainer ring for the narrow hole has the advantages of simple structure, reasonable design and convenience for large-scale popularization and use; through adopting the retaining ring cover to realize the precompression of retaining ring for the external diameter of retaining ring is less than the aperture of installation retaining ring hole on the work piece, and the retaining ring that the rethread ejector pin will compress is jacked into the hole of installation retaining ring on the work piece, and in the round hole inside groove department of its hole, the retaining ring just can automatic card go into the assembly of round hole inside groove completion retaining ring, has effectively replaced the assembly methods of traditional use jump ring pincers, assembly operation is simpler, labour saving and time saving, also can accomplish the assembly operations of retaining ring fast, accurately in some narrow positions and work piece hole aperture simultaneously.
Drawings
The utility model has the following drawings:
FIG. 1 is an external construction diagram of the present utility model;
FIG. 2 is a cross-sectional view of the present utility model;
fig. 3 is a partial enlarged view of fig. 2 at the point a.
Detailed Description
As shown in the figure, the assembly fixture for the retainer ring for the narrow hole comprises a sleeve 5, wherein a push rod 7 is movably arranged in the sleeve 5, the push rod 7 is connected with a movable driving assembly, in the embodiment, the movable driving assembly comprises an air cylinder 2, a piston rod of the air cylinder 2 is connected with the push rod 7, the air cylinder 2 is connected with an air pump, and a handle 4 is arranged on a base and used for controlling the operation of the air pump. Of course, besides the cylinder, the movable driving assembly can also adopt a common linear driving mechanism such as a hydraulic cylinder, a cam structure, a screw rod and the like to drive the ejector rod 7 to perform reciprocating linear movement. One end of the sleeve 5 is provided with a check ring sleeve 6, an inner ring 8 of the check ring sleeve 6 can be used for clamping the compressed check ring, the aperture of the inner ring 8 of the check ring sleeve 6 is smaller than the aperture of an inner hole of the check ring to be installed on a workpiece, and the ejector rod 7 can jack the compressed check ring in the check ring sleeve 6 into a check ring installation groove of the inner hole of the check ring to be installed on the workpiece. Further, the retainer ring sleeve 6 is in threaded connection with the sleeve 5, so that the retainer ring sleeve 6 with the aperture of the inner ring can be replaced conveniently. The sleeve 5 is fixedly arranged on the mounting frame 3, and the mounting frame 3 is fixedly connected with the base 1. The cylinder body of the cylinder 2 is arranged on the base, and the cylinder 2 is positioned below the sleeve 5.
The working principle of the utility model is as follows: firstly, compressing and pressing a retainer ring into an inner ring 8 of a retainer ring sleeve 6, then moving an inner hole of a workpiece to be filled with the retainer ring to the upper side of the retainer ring sleeve 6, aligning the inner hole of the workpiece with the inner ring 8 of the retainer ring sleeve 6, then controlling a cylinder 2 to drive a push rod 7 to act, enabling the push rod 7 to push the retainer ring compressed in the inner ring 8 of the retainer ring sleeve 6 to move and enter the inner hole of the workpiece, and as the retainer ring is pushed continuously, when the retainer ring moves to a circular inner groove of the inner hole of the workpiece, expanding and clamping the retainer ring into the circular inner groove, so that the assembly operation of the retainer ring is completed.
According to the structure, the pre-compression of the retainer ring is realized by adopting the retainer ring sleeve, the compressed retainer ring is ejected into the inner hole of the installation retainer ring on the workpiece by the ejector rod, so that the automatic push-in assembly of the retainer ring can be realized, the traditional assembly mode of using the clamp spring pliers is effectively replaced, the assembly operation is simpler, time and labor are saved, and meanwhile, the assembly operation of the retainer ring can be rapidly and accurately finished at some narrow positions and when the hole diameter of the inner hole of the workpiece is smaller.
