Description
Technical Field
The utility model relates to a wheel lathe's top device that stretches out and draws back especially realizes on wheel lathe's the equipment that has the top action demand that stretches out and draws back.
Background
Most of the telescopic centers of the current wheel lathes are driven by adopting a trapezoidal screw rod, but the trapezoidal screw rod has complex structure and low efficiency, the control error of the jacking force is large, and the centers are easy to lock.
Disclosure of Invention
The utility model aims at providing a wheel lathe's flexible top device to the requirement of wheel lathe dress card process.
The utility model adopts the technical proposal that: the oil cylinder pushes the movable center to extend out, flexible movement of the sleeve is achieved through the guide lubricating sleeve at the front end, and the bearing is installed in the middle to bear axial load.
The utility model discloses a wheel lathe's top device that stretches out and draws back, including hydro-cylinder, main shaft, ejector pin, thrust ball bearing, deep groove ball bearing, the lubricated cover of direction, top sleeve and top. The oil cylinder is arranged at the tail end of the main shaft, the front end of the main shaft is fixedly connected with the guide lubricating sleeve, the main shaft is a hollow shaft, the ejector rod is arranged in the main shaft, the tail end of the ejector rod is connected with a piston rod of the oil cylinder, a thrust ball bearing and a deep groove ball bearing are arranged at the front end of the ejector rod, the deep groove ball bearing is arranged in a cavity of the tip sleeve, the tip is arranged at the front end of the tip sleeve, and the tip sleeve is arranged in the guide sliding sleeve and is.
The oil cylinder is a high-thrust oil cylinder.
The thrust ball bearing and the deep groove ball bearing are arranged between the ejector rod and the top sleeve, the thrust ball bearing and the deep groove ball bearing are mainly used for bearing the axial force of the top, the main shaft is prevented from rotating and transmitting to the oil rod, and the top jacking force is directly controlled by controlling the pressure of the oil cylinder; the front end is equipped with the direction lubricated cover, and at top telescopic slip in-process, adopt the direction lubricated cover inner wall to set up the coating and play the lubrication action, the telescopic non-maintaining cycle of extension to can provide fine direction precision.
The utility model discloses the principle of the flexible top device of wheel lathe does: the oil cylinder is used as a main power source, the rotation of the bearing is used for realizing the connection between the rotation and the fixed part, and finally, the positioning precision and the stability required by the tip are kept through the guide sliding sleeve.
Through the inspection, adopt the utility model discloses a flexible top device of wheel lathe uses on the numerical control wheel lathe, can satisfy the requirement to the tight work in top of required part.
Drawings
Fig. 1 is a schematic structural diagram of the present invention.
In fig. 1: 1. the device comprises a large-thrust oil cylinder, 2 ejector rods, 3 main shafts, 4 thrust ball bearings, 5 deep groove ball bearings, 6 guide lubricating sleeves, 7 tip sleeves, 8 tips and 9 box bodies.
Detailed Description
The invention will be further described and explained with reference to the drawings.
Referring to fig. 1, the utility model discloses a big thrust hydro-cylinder 1, main shaft 3, ejector pin 2, thrust ball bearing 4, deep groove ball bearing 5, the lubricated cover 6 of direction, top sleeve 7 and top 8. The large thrust oil cylinder 1 is arranged at the tail end of the main shaft 3, the large thrust oil cylinder 1 is connected with the box body 9 through a screw, the front end of the main shaft 3 is fixedly connected with the guide lubricating sleeve 6, the main shaft 3 is a hollow shaft, the ejector rod 2 is arranged in the main shaft 3, the tail end of the ejector rod 2 is connected with a piston rod of the oil cylinder 1, the front end of the ejector rod 2 is provided with a thrust ball bearing 4 and a deep groove ball bearing 5, and the deep groove ball bearing 5 is arranged in a cavity of the tip sleeve. The centre 8 is arranged at the front end of the centre sleeve 7, and the centre sleeve 7 is arranged in the guide sliding sleeve and is in sliding connection with the guide sliding sleeve, so that the centre sleeve 7 can slide in the guide sliding sleeve 6. The utility model discloses a thrust ball bearing 4 is used for bearing the top axial load who applys.
