Abstract
The utility model relates to a take pneumatic cylinder piston rod of flat head, including piston rod, flat head, piston rod one end be equipped with the hookup cylinder, flat head on be equipped with and hookup cylinder complex blind hole, hookup cylinder and blind hole adopt interference fit to be connected, the blind hole in still be equipped with the hot charge exhaust hole. Compared with the prior art, the utility model has the advantages that: the piston rod and the flat head in the device are split parts, so that the processing difficulty of equipment is effectively reduced, and the piston rod and the flat head are connected in an interference fit manner, so that the piston rod and the flat head are safe and reliable, and the cost is low.
Description
Technical field
The utility model relates to the hydraulic machinery technical field, particularly a kind of hydraulic cylinder piston rod with homalocephalus.
Background technique
The piston rod of oil hydraulic cylinder and equipment adopt homalocephalus to be connected, and existing Placement has: piston rod and homalocephalus are fabricated to that integral type, piston rod are threaded with the homalocephalus employing, piston rod is connected with homalocephalus employing snap ring.Wherein, The piston rod of piston rod and homalocephalus integral type is the most firm, but wherein the size of homalocephalus is bigger than piston rod, and the blank dimension that needs is big; Cause Forging Technology complicated; The manufacture cost that causes this kind piston rod is than higher, the occasion that the piston rod incompatibility high temperature of other Connecting format is moist, impact shock is big, and screw thread is perishable, loosening and cause thread failure; Throat depth is not enough, the occasion that the incompatibility impact shock is big, tensile force is big; Piston rod and homalocephalus snap ring connecting mode are because of the existence in gap, the occasion that the incompatibility impact shock is big; Piston rod and homalocephalus screw thread, welding connecting mode be because worker's required precision of double thread is very high, otherwise have only several roads screw thread of limited quantity to work, and do not reach the tensile force of design.
Summary of the invention
The purpose of the utility model provides a kind of hydraulic cylinder piston rod with homalocephalus, and piston rod in this device and homalocephalus are the split part, and adopts interference fit to connect, and is safe and reliable, and with low cost.
For realizing above-mentioned purpose, the utility model is realized through following technological scheme:
A kind of hydraulic cylinder piston rod with homalocephalus; Comprise piston rod, homalocephalus, described piston rod one end is provided with the connection cylinder, and described homalocephalus is provided with and connects the blind hole that cylinder cooperates; Described connection cylinder adopts interference fit to be connected with blind hole, also is provided with the hot charging exhaust port in the described blind hole.
Compared with prior art, the utility model has the advantages that: piston rod in this device and homalocephalus are the split part, have effectively reduced the difficulty of processing of equipment, and adopt interference fit to connect, and be safe and reliable, and with low cost.
Description of drawings
Fig. 1 is the structural representation of the utility model.
Among the figure: 1-piston rod 2-blind hole 3-connects cylinder 4-hot charging exhaust port 5-homalocephalus
Embodiment
Describe in further detail below in conjunction with the embodiment of accompanying drawing the utility model.
See Fig. 1; A kind of hydraulic cylinder piston rod with homalocephalus; Comprise piston rod 1, homalocephalus 5, described piston rod 1 one ends are provided with and connect cylinder 3, and described homalocephalus 5 is provided with and connects the blind hole 2 that cylinder 3 cooperates; Connect cylinder 3 and adopt interference fit to be connected, also be provided with hot charging exhaust port 4 in the described blind hole 2 with blind hole 2.
This device when installation and processing, at first with the blind hole 2 of homalocephalus 5 and piston rod 1 one ends connect cylinder 3 hot chargings, piston rod 1 is welded with the connection part cylindrical place of homalocephalus 5 get final product then.
