Description of reference numerals:

1. a threaded sleeve; 2. a support; 3. a movable screw; 4. rotating the handle; 5. locking the nut; 6. positioning a plate; 7. fixing the screw rod; 8. adjusting the nut; 9. a motor base; 10. base channel steel; 11. carrying out top thread; 12. and a baffle plate.

Detailed Description

The embodiments of the invention will be described in detail below with reference to fig. 1 to 3, but the invention can be implemented in many different ways as defined and covered by the claims.

It is to be understood that the following detailed description is exemplary and is intended to provide further explanation of the invention as claimed, unless otherwise specified, and all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this disclosure belongs.

According to the technical problems recorded in the background art, the jackscrew 11 passes through the baffle 12 with the threaded hole to act on the side surface of the motor base 9, and the motor on the motor base 9 is moved by pushing the motor base 9, but the jackscrew 11 of the current walking beam machine is thin and long and the used metal material is unqualified, the working end surface of the jackscrew 11 is easy to slip after contacting with the motor base 9, and even the jackscrew 11 bends and deforms seriously, so that the efficiency of motor moving operation is influenced.

With reference to fig. 1 to 3, the utility model provides a tensioning device for a motor jackscrew working part, which comprises a positioning plate 6 capable of being matched with the inner wall of a base channel steel 10, wherein a fixing screw 7 is welded on the upper surface of the positioning plate 6 along the longitudinal direction, the fixing screw 7 is simultaneously screwed with a locking nut 5 and an adjusting nut 8, the locking nut 5 can be matched with the upper surface of the base channel steel 10, and the adjusting nut 8 is positioned above the locking nut 5; the upper portion of adjusting nut 8 still revolves and is equipped with movable screw rod 3, the top of movable screw rod 3 is fixed to be provided with and is used for revolving the swivel nut 1 who establishes jackscrew 11.

According to the structure of above-mentioned embodiment can discover, because locating plate 6 can cooperate with the inner wall of base channel-section steel 10, and lock nut 5 can cooperate with the higher authority of base channel-section steel 10, locating plate 6 just can be fixed in the inside of base channel-section steel 10 by lock nut 5 like this, fixing screw 7 is also fixed simultaneously, the staff rotates adjusting nut 8 just so and can make 3 longitudinal movement of movable screw rod, make 3 longitudinal movement of movable screw rod drive swivel nut 1, swivel nut 1 longitudinal movement just can be given and wear to establish 11 certain effort of jackscrew wherein, prevent 11 radial movement of jackscrew.

With reference to fig. 1 to 3, in order to facilitate the worker to rotate the adjusting nut 8, the outer edge of the adjusting nut 8 is welded with a rotating handle 4.

With reference to fig. 1 and fig. 3, a support 2 having an arc-shaped groove is fixedly disposed on the movable screw rod 3, and the threaded sleeve 1 is fixedly connected to the support 2.

The utility model discloses an in the above-mentioned embodiment, set up the support 2 that has the arc wall between activity screw rod 3 and swivel nut 1, can fix swivel nut 1 better, because when the taut swivel nut 1 of activity screw rod 3, swivel nut 1 need bear great pulling force, and this embodiment can make swivel nut 1 can not break away from activity screw rod 3 when bearing great pulling force, and of course, the staff also can directly weld swivel nut 1 on activity screw rod 3.

It should also be noted that the above-mentioned embodiment of this utility model is described in detail with the walking beam machine as an example, to the motor jackscrew of the plateau machine that the bore is great and length is shorter, the staff can the optional use, according to the utility model discloses a structure can discover, locating plate 6 can be followed the inside of base channel-section steel 10 and taken out after unscrewing lock nut 5, and swivel nut 1 also can be followed jackscrew 11 and unscrewed, and is visible, this utility model's installation and dismantlement are all very simple, and to the plateau machine motor jackscrew that the problem of skidding often appears not taking place, the staff can only install when needing, takes off after the operation is accomplished.

To sum up, this utility model creatively has utilized the structural feature of base channel-section steel 10, fixes locating plate 6 in the inside of base channel-section steel 10, then closes fixing screw 7 and movable screw 3's adjusting nut 8's rotation by the while soon and realizes movable screw 3's axial displacement to by the work portion of the taut jackscrew 11 of swivel nut 1, just so can avoid the side of jackscrew 11 and motor base 9 to skid, thereby guarantee that the staff accomplishes smoothly and moves the motor operation.
