The utility model relates to a wheel lathe double cylinder closing device especially realizes the drive to the wheel pair when wheel pair is processed to wheel lathe.
Background
At present, the running speed of a high-speed rail is accelerated, the running mileage is increased, the maintenance efficiency of a vehicle wheel set is higher and higher, the wheel set is clamped by a disc chuck jaw in a traditional wheel lathe, the preparation period is long, the workload is large, bearings on two sides of the wheel set need to be dismounted from the wheel set, then the wheel set is hoisted into a machine tool to be clamped and aligned, the processing is carried out, the efficiency is low, and the resource loss is large.
Disclosure of Invention
The utility model aims at providing a double-cylinder closing device of wheel lathe wheel pair to the processing requirement of rail vehicle wheel pair.
The utility model adopts the technical proposal that: a double-oil-cylinder pressing device comprises a box body, oil cylinders, a support, a main shaft, a friction wheel mounting frame and friction wheels. The main shaft is arranged on two sides of the front end of the box body, the oil cylinders are arranged on two sides of the rear end of the box body, one end of the support is sleeved on the main shaft and is in radial limit connection with the main shaft through a key groove, the other end of the support is hinged on a piston rod of the oil cylinder, the oil cylinder drives the main shaft to rotate through the support, and the end part of a cylinder body of the oil cylinder is hinged on the box body; one end of the friction wheel mounting frame is fixed on the main shaft, the other end of the friction wheel mounting frame is provided with a friction wheel, the friction wheel mounting frame and the oil cylinder are connected through the main shaft, and the wheel pair is pressed through the friction wheel on the friction wheel mounting frame.
One end of the support is sleeved on the main shaft and is connected with the main shaft in a radial limiting mode through a key groove, namely one end of the support is in a sleeve shape, an axial key is arranged in the sleeve, an axial groove matched with the axial key is formed in the main shaft, the sleeve is sleeved on the main shaft, and the axial key is inserted into the axial groove to form the key groove to be matched and realize radial limiting.
The utility model discloses the principle of double cylinder closing device who says does: the support is connected with the main shaft through a key, the support is driven to rotate through the oil cylinder, the main shaft is driven to rotate by the support, a friction wheel is installed at the front end of the main shaft, and the friction wheel presses the wheel pair.
Through the inspection, adopt the utility model discloses the hydro-cylinder closing device of saying uses on the wheel lathe, can satisfy the requirement that compresses tightly required wheel pair.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a rear view of FIG. 1;
FIG. 3 is a left side view of FIG. 1;
fig. 4 is a sectional view a-a of fig. 1.
Detailed Description
The structure and principle of the dual-cylinder pressing device of the present invention will be further described and explained with reference to the accompanying drawings.
Referring to fig. 1-3, the utility model comprises a box body 2, an oil cylinder 1, a bracket 3, a main shaft 5, a friction wheel mounting frame 6 and a friction wheel 7. The main shaft 5 is arranged on two sides of the front end of the box body 2, the oil cylinders 1 are arranged on two sides of the rear end of the box body 2, one end of the support 3 is sleeved on the main shaft 5 and is in radial limit connection with the main shaft 5 through a key groove, the other end of the support 3 is hinged on a piston rod 1.1 of the oil cylinder 1 through a pin, the oil cylinder 1 drives the main shaft 5 to rotate through the support 3, and the end part of a cylinder body 1.2 of the oil cylinder 1 is hinged on the box body; one end of the friction wheel mounting frame 6 is fixed on the main shaft 5, the other end of the friction wheel mounting frame is provided with a friction wheel 7, the friction wheel mounting frame 6 and the oil cylinder 1 are connected through the main shaft 5, and the wheel pair 8 is pressed through the friction wheel 7 on the friction wheel mounting frame 6.
The one end suit of support 3 is on main shaft 5 and is connected with main shaft 5 radial spacing through the keyway, means that 3 one end of support is the sleeve form, establishes axial key 4 in the sleeve, is equipped with on the main shaft 5 with axial key complex axial groove, the sleeve suit is on main shaft 5, axial key 4 inserts the axial groove and forms the keyway cooperation and realize radial spacing. Fig. 2 is a rear view of fig. 1, with the spindle 5 mounted in the housing 2 and the pair of wheels 8 to be machined placed in front of the housing 2.
Fig. 4 is a sectional view taken along line a-a of fig. 1, the bracket 3 and the main shaft 5 are driven by a key 4, the front end of the main shaft 5 is provided with a friction wheel mounting frame 6, a friction wheel 7 is arranged on the friction wheel mounting frame 6, and the main shaft 5 is arranged in the box body 2 by a bearing.
During the use, the utility model discloses the installation is fixed on the lathe to make and be processed wheel pair 8 and place in box the place ahead. The oil cylinder is started, the main shaft is driven to rotate by the oil cylinder driving support, the main shaft is installed in the box body through the bearing, the main shaft drives the friction wheel installation frame to rotate, and the friction wheel at the other end of the friction wheel installation frame compresses the wheel pair.
