Description
Technical Field
The utility model relates to a specialized tool for following fluid coupling ware is dismantled on motor shaft belongs to workshop tool technical field.
Background
A fluid coupling is a mechanical device for connecting a power source (usually an engine or a motor) and a working machine to transmit rotary power, and is widely used in industrial and mining enterprises at present. The existing method for disassembling the hydraulic coupler mainly adopts a drawing method, which has the defects of high disassembling difficulty, low efficiency and manpower and material waste, and the hydraulic coupler shell is made of an aluminum alloy material, so that the hydraulic coupler is poor in stress capability and easy to damage during drawing. It is therefore necessary to design a simple and effective fluid coupling tool.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a specialized tool for dismantling fluid coupling ware to the drawback of prior art to reduce fluid coupling ware and dismantle the degree of difficulty, improve and dismantle efficiency, and ensure fluid coupling ware's safety.
In order to achieve the above purpose, the utility model adopts the following technical scheme:
a special tool for disassembling a hydraulic coupler comprises an ejector rod, a sleeve, a jacking nut and a disc frame, wherein the front end of the ejector rod is abutted to the end face of a motor shaft connected with the hydraulic coupler, the rear end of the ejector rod sequentially penetrates through the sleeve, the jacking nut and the disc frame, external threads at the front end of the sleeve are matched with internal threads in a shaft hole of the hydraulic coupler, the disc frame is connected with the sleeve through a connecting mechanism, and the jacking nut is matched with the ejector rod through threads.
According to the special tool for disassembling the hydraulic coupler, the connecting mechanism between the disc rack and the sleeve is the tensioning screw rod (3), the front end of the tensioning screw rod (3) is connected with the flange at the rear end of the sleeve, and the rear end of the tensioning screw rod is connected with the disc rack.
The special tool for disassembling the hydraulic coupler is characterized in that the front end of the ejector rod is provided with an external thread matched with a threaded hole in the end face of a motor shaft.
The special tool for disassembling the hydraulic coupler is characterized in that the two tensioning screw rods (3) are symmetrically arranged on two sides of the ejector rod.
Above-mentioned specialized tool for dismantling fluid coupling ware, be clearance fit between ejector pin and the sleeve pipe, between ejector pin and the plate rail.
The utility model discloses the utilization provides the dismantlement power through screw thread matched with jacking nut and ejector pin, and the shaft hole position that the dismantlement power transmitted hydraulic coupler through the sleeve pipe, and operating personnel only need rotatory jacking nut can extract hydraulic coupler, and not only greatly reduced hydraulic coupler's the dismantlement degree of difficulty, improved dismantlement efficiency, dismantle the shell of in-process hydraulic coupler moreover and can not warp to hydraulic coupler's safety has been ensured.

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Fig. 1 is a schematic structural view of the present invention;
fig. 2 is a schematic view of the using method of the present invention.
The reference numbers in the figures are as follows: 1. ejector pin, 2, sleeve pipe, 3, tensioning lead screw (3), 4, jacking nut, 5, plate rail, 6, motor, 7, fluid coupling.
Detailed Description
The utility model provides a specialized tool for dismantling fluid coupling ware, this instrument can make operation personnel safety, extract fluid coupling ware from the motor shaft fast.
Referring to fig. 1, the utility model discloses mainly include ejector pin 1, sleeve pipe 2, taut lead screw (3) 3, jacking nut 4 and plate rail 5, the front end of sleeve pipe 2 has the external screw thread, and the rear end is equipped with the flange, and sleeve pipe 2 links together through taut lead screw (3) 3 with the plate rail 5 of device rear end, and in the threaded hole on the back screw in motor shaft terminal surface was worn together with sleeve pipe 2 to ejector pin 1. In the use process, the external thread of the sleeve 2 is connected with the mounting thread in the shaft hole of the hydraulic coupler, a jacking nut 4 is mounted between the rear end of the ejector rod 1 and the rear end disc frame 5 of the device, and the hydraulic coupler can be pulled out by rotating the jacking nut 4 with a wrench after the tool is mounted.
The working process of the utility model is as follows: when the hydraulic coupler needs to be disassembled, an operator firstly connects the sleeve 2 with the external thread with the disc frame 5 through the tensioning screw rod (3) 3, and the ejector rod 1 and the sleeve 2 penetrate together and then rotate to enter a shaft end screw hole of the motor. The external thread of the sleeve 2 is connected with the threaded connection in the coupler shaft hole, the jacking nut 4 is arranged in the gap between the sleeve 2 and the disc frame 5, the jacking nut 4 is in threaded fit with the ejector rod 1, and the hydraulic coupler can be pulled out by rotating the jacking nut 4.
The tool mainly utilizes the jacking nut to push the ejector rod, and the hydraulic coupler is pulled out from the shaft through the counterforce of the ejector rod. The disassembling method effectively reduces the disassembling difficulty of the hydraulic coupler and improves the operation efficiency.
The tool does not need to use any external energy in the whole working process, is convenient and quick to operate, and can ensure the safety of the hydraulic coupler.
