Abstract

The utility model provides a drawing device used for shafts, which comprises a drawing screw, wherein a support saddle and a handwheel nut is sleeved on the drawing screw; a thrust bearing which is used for reducing friction is arranged between the support saddle and the handwheel nut; a nipple which is connected with a pressure wheel shaft is arranged at the front end of the drawing screw; and a screw thread used for the rotation of the handwheel nut is arranged at the back end of the drawing screw. The drawing device has the characteristics of simple structure, convenient use and the like.

Description

The axle drawbench

Technical field

The utility model relates to a kind of and uses drawbench, is used for the dismounting of casting machine wheel pressing shaft.

Background technology

The dismounting of casting machine pinch roller can be hung oneself out pinch roller integral body after must earlier wheel pressing shaft being removed because design and installation and position are limit from frame, generally primitive axis is cut off length consuming time and cost height when needing the disintegration pinch roller usually with acetylene.

Summary of the invention

The purpose of this utility model just provides a kind of and uses drawbench, and this drawbench can easily be pulled out wheel pressing shaft from frame, thereby reaches the raising removal efficiency, reduces labour intensity and maintenance cost.

The purpose of this utility model can realize by following scheme: comprise a drawing screw rod, be with bearing and hand wheel nut on the drawing screw rod, between bearing and hand wheel nut, be provided with thrust bearing, be used to alleviate friction, the front end of drawing screw rod is provided with the nipple that is connected with wheel pressing shaft, and the rear end is provided with the screw thread for the hand wheel nut rotation.

The utlity model has characteristics such as simple in structure, easy to use.

Description of drawings

Fig. 1, the utility model structural representation.

The specific embodiment

Contrast Fig. 1 as can be known, the utility model comprises a drawing screw rod 1, be with bearing 2 and hand wheel nut 3 on the drawing screw rod 1, between bearing 2 and hand wheel nut 3, be provided with thrust bearing 4, be used to alleviate friction, the front end of drawing screw rod 1 is provided with the nipple 5 that is connected with wheel pressing shaft, and the rear end is provided with the screw thread for the hand wheel nut rotation.

Operation principle of the present utility model is as follows:

1, hangs pinch roller with driving, prevent that wheel pressing shaft from removing the back pinch roller damage equipment that drops;

2, remove wheel pressing shaft two ends gland, the nipple 5 of drawing screw front end be connected with wheel pressing shaft,

3, rotate hand wheel nut, by spiral power transmission principle, wheel pressing shaft is pulled out from frame.

Claims

1 one kinds of axle drawbench, it is characterized in that comprising a drawing screw rod (1), be with bearing (2) and hand wheel nut (3) on the drawing screw rod (1), between bearing (2) and hand wheel nut (3), be provided with thrust bearing (4), the front end of drawing screw rod (1) is provided with the nipple (5) that is connected with wheel pressing shaft, and the rear end is provided with the screw thread for the hand wheel nut rotation.
