Problems solved by technology

Since the apron has a certain amount of interference, the manual installation of the apron is uneven in force, and there is a gap in the sealing groove, so it is easy to cause the apron to twist and deform, and work with stress

Embodiment Construction

[0017] A sealing rubber ring installation introduction device, including a positioning support device for fixing the actuator, the positioning support device includes an L-shaped support 1, a V-shaped block 4 is installed on the upper part of the L-shaped support 1, and the actuator 8- One side is installed close to the V-shaped block 4, and the other side is pressed with a pressure plate 5, and fastened with bolts 7 and nuts 6 to press the actuator 8, and a threaded guide matching its inlet thread is set at the entrance of the actuator 8. Sleeve 3, the inner surface of the threaded guide sleeve 3 is bell-shaped, used to guide the sealing rubber ring, and the positioning sleeve 2 is installed on the threaded guide sleeve 3 to ensure that the piston rod is concentric with the outer cylinder during installation and ensure that the rubber ring is protected. The force is uniform, reducing the chance of the apron twisting during the installation process. Convenient clamping and ali...

Abstract

The invention relates to a guide-into device and a guide-into method for installation of seal rubber rings, and belongs to the technical field of machining. The device comprises a locating and supporting device used for fixing an actuator cylinder, a threaded guide sleeve matched with threads at an inlet of the actuator cylinder is arranged on the inlet of the actuator cylinder, the inner surface of the threaded guide sleeve is of a horn mouth shape, and a locating sleeve is installed on the threaded guide sleeve. The locating and supporting device comprises an L-shaped support, a V-shaped block is installed at the upper part of the L-shaped support, one side of the actuator cylinder is closely attached to the V-shaped block, the other side of the actuator cylinder is pressed by a pressing plate and fastened by a nut, and the actuator cylinder is pressed. According to the guide-into device and the guide-into method, piston rods with the rubber rings can be installed in a guide-into mode, special requirements for equipment and operating personnel are avoided, the product quality is guaranteed, the technological problems of production are solved, products are more stable and reliable, and economic benefits are created.

Description

technical field [0001] The invention relates to a sealing rubber ring installation and introduction device and introduction method, belonging to the technical field of machining. Background technique [0002] O-ring is a common sealing medium. When working, the O-ring is installed in the sealing groove. Since the groove width is greater than the cross-sectional diameter d2 of the O-ring, and the groove depth H is less than d2, the O-ring after assembly There is a certain amount of compression in the axial direction to produce elastic deformation, and there is a certain equivalent Cauchy stress on the contact surface to play a sealing role. Under the action of the medium pressure, the O-ring has a displacement tendency, which may move to the low-pressure side, and increase the elastic deformation, tighten and close the sealing gap, and enhance the sealing effect. The compression of the O-ring after installation should be appropriate. The compression rate of the ordinary rubb...
