Description

Power head device for turret lathe

Technical Field

The utility model belongs to the field of lathe accessories, and particularly relates to a power head device for a turret lathe.

Background

With the continuous progress of society and the continuous development of processing industry, the requirements of people on the convenience, rigidity, efficiency and the like of processing equipment are continuously improved. The original lathe can not meet the requirements of people, the machining industry has more and more great requirements on turning and milling composite lathes, and meanwhile, the requirements on the machining efficiency, the rigidity and the like of a machine tool are more and more emphasized.

Although the traditional turret type turning and milling combined lathe can sufficiently cope with simple processing environments and can freely cope with simple milling work with small processing amount, the efficiency cannot keep up with the traditional turret type turning and milling combined lathe when the lathe is used in the environments with large processing amount.

Disclosure of Invention

The utility model aims to overcome the defects and shortcomings of the prior art and provide the power head device for the turret lathe, which has the advantages of reliable quality, convenience in adjustment and high machining efficiency.

In order to achieve the above purpose, the technical solution of the utility model is as follows: the utility model provides a power head device for turret lathe, includes body, bearing frame, output shaft and input shaft, pass through drive gear transmission power, its characterized in that between output shaft and the input shaft: the input shaft is sleeved in the bearing seat through an upper end bearing and a needle bearing, and an eccentric pin is fixed at the bottom of the body on one side of the bearing seat.

This internal waterproof sealing device that is provided with of angular contact bearing's front end, waterproof sealing device includes sealing washer and manger plate groove, the sealing washer is located between angular contact bearing and the manger plate groove.

And the tail end of the output shaft is sleeved with a locking nut.

A plurality of water way holes are distributed in the body.

The transmission gear is a gleason tooth type conical gear.

Compared with the prior art, the utility model has the following advantages:

1. according to the utility model, by utilizing the characteristics of small contact area, high rotating speed and the like of the angular contact ball bearing, the angular contact ball bearing is combined and matched with the output shaft, so that the rotating speed can still reach 6000rpm while the integral rigidity of the power head is improved; the transmission gear adopts a conical gear structure, and a needle bearing is arranged at the lower end of the input shaft, so that the transmission of large torque is facilitated; the axis of the power head can be quickly adjusted to be parallel to the main shaft through the eccentric pin, so that the power head has the capability of quick adjustment, and convenience is provided for quick installation and disassembly of the power head.

2. According to the utility model, the waterproof sealing device with the sealing ring and the water retaining groove is arranged in the body at the front end of the angular contact bearing, so that water can be effectively prevented from accumulating and entering the power head from the gap between the sealing ring and the shaft.

3. According to the utility model, a plurality of water channel holes are arranged in the body, and cutting fluid flows through the through holes among the body, the output shaft and the power head rear cover and finally flows out of the power head to play a role of internal cooling.

Drawings

Fig. 1 is a schematic structural view of the present invention.

Fig. 2 is a partially enlarged view of a portion a in fig. 1.

Fig. 3 is a schematic view of the installation of the present invention.

In the figure: the bearing comprises a body 1, a bearing seat 2, an output shaft 3, an input shaft 4, a transmission gear 5, an angular contact bearing 6, a rear end bearing 7, an upper end bearing 8, a needle bearing 9, an eccentric pin 10, a waterproof sealing device 11, a sealing ring 12, a water retaining groove 13, a locking nut 14 and a waterway hole 15.

Detailed Description

The present invention will be described in further detail with reference to the following description and embodiments in conjunction with the accompanying drawings.

Referring to fig. 1-2, a power head device for a turret lathe comprises a body 1, a bearing seat 2, a hollow output shaft 3 and an input shaft 4, wherein a plurality of water passage holes 15 are distributed in the body 1, power is transmitted between the output shaft 3 and the input shaft 4 through a transmission gear 5 of a gleason toothed bevel gear, the transmission gear 5 is meshed with a gear on the input shaft 4, the transmission gear 5 is connected to the output shaft 3 in a key connection mode, a locking nut 14 is connected to the tail end of the output shaft 3 in a sleeved mode, the bearing seat 2 is connected to the bottom of the body 1 in a screwed mode through threads, the output shaft 3 is connected to the body 1 in a sleeved mode through two angular contact bearings 6 located at the front end and a rear end bearing 7 located at the rear end, a waterproof sealing device 11 is arranged in the body 1 at the front end of the angular contact bearings 6, the waterproof sealing device 11 comprises a sealing ring 12 and a water retaining groove 13, the sealing ring 12 is positioned between the angular contact bearing 6 and the water retaining groove 13, the input shaft 4 is sleeved in the bearing seat 2 through two upper end bearings 8 positioned at the upper end and a needle bearing 9 positioned at the lower end, and the bottom of the body 1 at one side of the bearing seat 2 is fixedly provided with an eccentric pin 10.

When the device is installed, the bearing seat 2 is inserted into the installation hole A, the eccentric pin 10 is inserted into the adjusting hole B, and according to the principle that two points are arranged in a straight line, the power head can deviate by taking the bearing seat 2 as the center of a circle in the rotating process of the eccentric pin 10, so that the axis of the power head is quickly adjusted to be parallel to the main shaft, and the specific installation schematic diagram is shown in figure 3.

The power head can adjust the fit clearance between the gears at any time only by rotating the bearing seat 2 before assembly. This is because the distance (i.e. the gap) between the gear on the input shaft 4 and the transmission gear 5 can be increased by the rotation of the bearing seat 2 and the body 1 through the screw thread connection. The transmission gear 5 is connected with the output shaft 3 through a key, so that the power from the input shaft 4 is transmitted.
