Description

Technical Field

[0001] The utility model relates to the technical field of sealing ring installation, and more particularly to a small-diameter deep-hole sealing ring filling device. Background Art

[0002] The installation equipment for sealing rings in holes is widely used in the field of automated assembly. For example, some hydraulic valve bodies, gas-liquid connection joints, and automobile brake system cylinders are used. The existing sealing ring installation equipment is designed for working conditions with large inner diameters and shallow installation depths of installation holes. The solution is to use a fixture to shape the sealing ring into a fixture with a diameter smaller than the hole diameter. The sealing ring is then inserted into the installation position of the sealing ring in the hole together with the shaping fixture. The fixture then pulls the sealing ring back or uses compressed air to blow the sealing ring to complete the installation.

[0003] For installation conditions where the inner diameter of the mounting hole is small and the depth is deep, the fixture design needs to be higher due to the depth, while the diameter of the hole requires the fixture diameter to be smaller as well.

In addition, the directional terms mentioned in the following embodiments, such as "up", "down", "left", "right", etc., are only referenced to the directions of the drawings. Therefore, the directional terms used are used to illustrate rather than limit the invention of the present invention.

[0036] The present invention will be further described below with reference to the accompanying drawings and preferred embodiments.

[0037] Example: A small diameter deep hole sealing ring filling device, see attached Figure 1 -Attached Figure 8 , including a positioning mechanism 1, a tapered sleeve 3 and an installation mechanism 2, the positioning mechanism 1 is used to position and support the workpiece on which the sealing ring is to be installed; the tapered sleeve 3 is arranged above the positioning mechanism 1 and can move up and down to approach and move away from the workpiece, the inner diameter of the tapered sleeve 3 gradually decreases from top to bottom and the minimum inner diameter of the tapered sleeve 3 is smaller than the aperture of the installation hole on the workpiece; the installation mechanism 2 is used to push the sealing ring to move downward to pass through the tapered sleeve 3 and then enter the installation hole of the workpiece; the installation mechanism 2 includes a first clamping jaw 231, and there are two first clamping jaws 231, and the two first clamping jaws 231 are vertically arranged. The two first clamping jaws 231 realize tightening and loosening of the sealing ring from the inside of the sealing ring by moving closer to and away from each other, and the two first clamping jaws 231 can move up and down to drive the sealing ring through the tapered sleeve 3 and into the installation hole.

[0038] When installing the sealing ring, the two first clamping jaws 231 are first inserted into the sealing ring. The two first clamping jaws 231 are then moved in opposite directions to tighten the two first clamping jaws 231 against the inner side of the sealing ring, thereby grasping the sealing ring. The cone sleeve 3 is then moved to the top of the workpiece. The two first clamping jaws 231 then drive the sealing ring through the cone sleeve 3. During the process of passing through the cone sleeve 3, the inner diameter of the cone sleeve 3 gradually decreases from top to bottom, thereby gradually reducing the outer diameter of the sealing ring. When the sealing ring passes through the cone sleeve 3, the diameter of the sealing ring is smaller than the diameter of the mounting hole on the workpiece, allowing the sealing ring to smoothly enter the mounting hole and reach the installation position, thereby completing the installation of the sealing ring. Since in this embodiment, the first clamping jaw 231 only needs to tighten the sealing ring and drive it to move, without having to reduce the diameter of the sealing ring, the strength requirement of the first clamping jaw 231 is reduced, making it easier to meet the strength requirement of the first clamping jaw 231 in the prior art, thereby improving the qualified rate of the sealing ring installation.
