Description
Technical Field
The utility model relates to a hydro-cylinder mounting structure, concretely relates to connection structure of hydro-cylinder ball seat main part and ball seat gland.
Background
The supporting leg oil cylinder plays a role in supporting equipment to keep a host machine to run stably, and when the host machine works, the load and dead weight of the equipment with the supporting leg oil cylinder structure are completely supported by four supporting legs, so that the supporting leg oil cylinder is required to work reliably, otherwise, the host machine body can be overturned. The support oil cylinder is supported on the ground, and the working ground is usually a non-paved road, so the support oil cylinder is usually provided with a ball seat and a ball head. In practice, the ball seat is subjected to a certain biasing force, which requires that the ball seat is automatically aligned. Traditional ball seat passes through screw fixed connection by ball seat main part, ball seat gland usually, is difficult to guarantee the concentric after the sphere on the ball seat main part and the sphere on the ball seat gland assemble. And the oil cylinder needs to support dozens of tons of force of the main machine, when the oil cylinder is in a correct angle, the ball seat gland which is not concentric with the ball seat main body is extruded by larger lateral force, so that the ball seat gland is easy to deform and damage due to stress, the ball seat gland is not flexibly matched with the ball head, the ball head cannot normally rotate and align, the performance of the oil cylinder of the supporting leg is influenced, and the construction safety of the main machine is reduced.
Patent documents entitled "support hinge device for preventing dump truck cylinder from bending moment" entitled as utility model patent No. 201320182641.4, No. CN 203161821U, and issued patent publication: the device comprises a carriage, a frame and an oil cylinder, wherein the oil cylinder is connected with the frame through a hinge, the carriage is connected with the frame through a hinge, the oil cylinder is connected with the front end of the carriage through a hinge, a cambered surface supporting device is adopted at the joint of the oil cylinder and the frame, and the oil cylinder swings in any direction. The cambered surface supporting device is supported by a ball head hinge, a ball head is arranged on the oil cylinder, a ball surface gland is connected to a ball head seat through a screw, the ball head is restrained in the ball head seat, and the oil cylinder swings in any direction by taking the ball head seat as a center. The patent document of application No. 201720078353.2, publication No. CN 2063972U, entitled "a side supporting device of single cylinder heading machine" discloses a utility model patent: the hydraulic cylinder comprises a single-cylinder double-piston-rod structure, and two groups of guide cylinders, bushes, a flange plate, a ball head, a gland and a ball head seat which are symmetrically arranged at two ends of the hydraulic cylinder, wherein a cylinder barrel of the hydraulic cylinder is connected with the whole machine through a pin shaft, and the end part of each piston rod penetrates through the guide cylinders and is connected with one end of the flange plate; the bushing is arranged on the outer side of the guide cylinder and forms a sliding pair with the guide cylinder; the flange plate is fixedly connected with the ball head and the guide cylinder; the ball head seat is connected with the gland to enable the ball head seat and the ball head to form a rotatable whole; a side support installation cavity is transversely formed in the position of a rear support front cross beam part of the heading machine, and the whole side support device is installed in the installation cavity. The above two utility model patent documents are all provided with a ball head hinge structure, but are not provided with a structure which can ensure the concentricity of the ball seat main body and the ball seat gland.
Disclosure of Invention
The main object of the present invention is to provide a connection alignment structure for a cylinder ball seat main body and a ball seat cover, which can ensure that the spherical surfaces of the ball seat main body and the ball seat cover are in a concentric position during the processing and installation.
The utility model discloses used technical scheme is: a connection alignment structure of an oil cylinder ball seat main body and a ball seat gland comprises a ball seat main body and a ball seat gland; the ball seat main body and the ball seat gland are fixedly connected together by a plurality of screws. At least two pairs of positioning pin mounting holes in transition fit with the positioning pins are further formed in the ball seat main body and the ball seat press cover; when the ball seat main body and the ball seat gland are machined and before the ball seat main body and the ball seat gland are fixedly connected together by using screws in use, the positioning pin is inserted into the positioning pin connecting hole.
Preferably, the center line of the positioning pin connecting hole is arranged on a cylindrical surface determined by the axes of the plurality of screws, and the diameter of the positioning pin mounting hole is equal to the outer diameter of the screw.
In order to ensure the concentricity of the ball seat main body and the spherical surface on the ball seat gland, firstly, a positioning pin with proper size and length is selected, after a through hole and a threaded hole which are used for fixedly connecting the ball seat main body and the ball seat gland together are processed, the ball seat gland and the ball seat main body are fixedly connected together by using a screw, then, a positioning pin connecting hole is processed according to the number and the diameter of the selected positioning pin, and after the positioning pin is installed, the corresponding spherical surface is processed. When the ball seat is used, the corresponding spherical head part of the piston rod is placed in a space determined by the spherical surfaces of the ball seat gland and the ball seat main body, the relative positions of the ball seat gland and the ball seat main body are accurately positioned by the positioning pin, and then the screws can be gradually screwed. The utility model discloses simple structure, convenient to use can guarantee well the concentricity of ball seat gland and ball seat main part in the use, is the connection counterpoint structure of a very outstanding hydro-cylinder ball seat main part and ball seat gland that uses very conveniently.
