Abstract

The utility model discloses a roller drawing and rotating device, which comprises a roller clamping position and a locking bolt, wherein the middle of the roller clamping position is provided with a through hole to cause the end part of the roller clamping position to form an annular structure and form a drawing and rotating position. The roller drawing and rotating device is characterized in that the drawing and rotating position is at least provided with one step. The roller drawing and rotating device has the advantages that the original drawing and rotating position groove is changed into a drawing and rotating step, and rest parts are milled to lower the weight of the drawing and rotating device and simultaneously increase the size of the original drawing and rotating position; because the drawing and rotating position is enlarged, a gap between a drawing and rotating bolt and the drawing and rotating position is enlarged, which is convenient for the drawing and rotating bolt to align at the drawing and rotating position; complex and difficult position aligning work which needs to be carried out when a roller is grinded each time is saved; the clamping difficulty is greatly improved; and operation time is saved, and the working efficiency is improved.

Description

Roll leads the commentaries on classics device

Technical field

The utility model relate to a kind of in order to lead change roll lead the commentaries on classics device, particularly a kind ofly can be used for leading the roll that changes sendzimir mill and lead the commentaries on classics device.

Background technology

Milling train is a kind of machinery that is used for the metal pressure rolling, and in use, roll needs often to grind to grinding machine; Need use to lead the rotation of commentaries on classics device drive roll in the process of lapping and grind, existing mode is to utilize leading shown in the figure one to change device to lead commentaries on classics, and having the transposition of leading of leading the commentaries on classics device now is a groove 9 leading on the commentaries on classics device; During use; To lead earlier changes the device clamping after locking on the roll, and handling is to grinding machine, again top 5 of grinding machine is changeed screw 6 and aims at respectively and lead through hole 8 and the groove 9 that changes on the device with leading; And the rotation of drive roll is ground; Because it is less usually to lead transposition groove 9, thereby often cause leading commentaries on classics device clamping difficulty on grinding machine, the time-consuming operating efficiency that reduces simultaneously.

Summary of the invention

The utility model technical problem to be solved provide a kind of conveniently lead change screw aim at lead transposition lead the commentaries on classics device, thereby reduce the clamping difficulty, increase work efficiency.

The said roll of the utility model leads the commentaries on classics device, comprises roll clamping position and lock-screw, and the middle part of said roll clamping position is that a through hole makes its end form loop configuration and constitute to lead transposition, it is characterized in that, leads to comprise at least one in the transposition and lead the turntable rank.

The said roll of the utility model leads the commentaries on classics device, and its advantage is following:

1. original transposition groove that leads is changed into and leads the turntable rank, the remainder mill off reduces to lead and changes the amount of thinking highly of, and has enlarged the size of leading transposition originally simultaneously;

2. owing to increase and to lead transposition, lead that to change screw very big with the space of leading transposition, conveniently leading changes screw and aims at and lead transposition, and the loaded down with trivial details and difficult contraposition work when having saved each grainding rolls improves the clamping difficulty greatly, saves the operating time and increase work efficiency.

Description of drawings

Fig. 1 leads the structural representation that changes device for existing roll;

Fig. 2 is the structural representation of grinding machine;

Fig. 3 leads the structural representation that changes device for the said roll of the utility model.

The specific embodiment

Roll leads the commentaries on classics device, and its structure is following:

Like Fig. 2, shown in Figure 3; Comprise roll clamping position 1 and lock-screw 4, roll clamping position 1 is in order to being connected with roll, and tightens up through lock-screw 4; The middle part of roll clamping position 1 has through hole 8 to make its end form loop configuration and formation is led transposition; Said through hole 8 mainly inserts in order to socket grinding machine top 5 and cooperation, is rotated by the leading commentaries on classics screw 6 drive roll clamping positions 1 that are installed on the flange 7, leads to have a step 3 in the transposition at least; Lead commentaries on classics screw 6 and roll clamping position 1 is rotated with step 3 interactions formation moments of torsion, thus the drive roll rotation.

Its advantage is, original transposition groove that leads is changed into and leads the turntable rank, and the remainder mill off has been equivalent to enlarge the size of leading transposition originally; Increase and to lead transposition, to change screw very big with the space of leading transposition owing to lead, and conveniently leading changes screw and aim at and lead transposition, and the loaded down with trivial details and difficult contraposition work when having saved each grainding rolls improves the clamping difficulty greatly, saves the operating time and increase work efficiency.

In sum, the utility model provides and can lead the commentaries on classics device by rolls quick, laborsaving installation and removal, effectively solves the problem that traditional roll leads changes the long-standing contraposition of device, clamping difficulty.

Claims

1. roll leads the commentaries on classics device, comprises roll clamping position, and the middle part of said roll clamping position has through hole to make its end form loop configuration and formation is led transposition, it is characterized in that, leads to have a step on the transposition at least.
