Abstract
The utility model discloses a kind of online arrangement for grinding of roll narrow zone, including rotation motor, clamping device and grinding wheel；The clamping device has to be connect and the screw rod coaxial with output shaft, the binding nut that is screwed on screw rod with the first part of the output axis connection of the rotation motor, with first part；The grinding wheel has central through hole and the cylinder shape groove coaxial with central through hole, the screw rod passes through the central through hole, and the grinding wheel is clamped between first part and binding nut by screwing the binding nut, the end of binding nut and screw rod is respectively positioned in the cylinder shape groove.The device can be such that the utilization rate of breaking-down roll improves.After coming into operation, roll founds slot-type using the time by original 10 days or so, and increase is used till now at 15 days or so, and 30% efficiency can be improved through counting.Roller consumption is reduced, roll changing time is reduced.Also greatly reduce the surface scratching of finished product to the reconditioning of narrow zone simultaneously.
Description
Technical field
The utility model relates to a kind of strip steel rolling tools, and in particular to online reconditioning roll is narrow when a kind of rolled band steel
The device in region.
Background technique
In ribbon steel field, the rolling of excellent spy's band is to the finish on roll pass surface and the guide groove surface contacted with steel band
Smoothness requirements are higher, when small defect occur in the two positions, it is necessary to the roll more renewed, and the roll changed is repaired
Mill is to solve this problem.This mode cost is larger, and efficiency is lower, and insitu moisture is larger dangerous.
Utility model content
Purpose of utility model: in order to solve the defects of prior art, the utility model provides a kind of roll narrow zone
Online arrangement for grinding, using the device can milling train dally when the small defect on roll pass and guide groove surface is repaired online
Mill.
Technical solution: a kind of online arrangement for grinding of roll narrow zone described in the utility model, including rotation motor,
Clamping device and grinding wheel；The clamping device has and the first part of the output axis connection of the rotation motor and first
Point connection and the screw rod coaxial with output shaft, the binding nut that is screwed on screw rod；The grinding wheel has central through hole and in
The coaxial cylinder shape groove of heart through-hole, the screw rod pass through the central through hole, and will be described by screwing the binding nut
Grinding wheel is clamped between first part and binding nut, and the end of binding nut and screw rod is respectively positioned in the cylinder shape groove.
Wherein, for the ease of holding reconditioning at a distance, the tail portion of the rotation motor is additionally provided with hand-held extension bar, described
Hand-held extension bar is removably connect with the rotation motor.
In order to improve the safety of reconditioning, the rotation motor selects Pneumatic rotary motor.
The utility model has the advantages that the utility model passes through clamping device by connecting clamping device on the output shaft of rotation motor
Clamping grinding wheel forms hand-held arrangement for grinding, realizes the online reconditioning of roll narrow zone, and the surface for avoiding strip finished product is drawn
Wound.Also, the end of the binding nut of clamping device and screw rod is arranged in the cylinder shape groove of grinding wheel, avoids protruding
The influence to grinding quality is caused outside grinding wheel.Mill roll number can be effectively reduced using the device, reduces roller consumption, raising is rolled
The utilization rate of roller.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the online arrangement for grinding of the utility model.
Specific embodiment
In the following, being described in further details in conjunction with attached drawing to the utility model.
As shown in Figure 1, the device includes being used for present embodiment discloses a kind of online arrangement for grinding of roll narrow zone
Pneumatic rotary motor can be selected as power mechanism, now in order to ensure the safety of reconditioning in the rotation motor 1 for driving grinding wheel 3 to rotate
Field connects gas source nearby.Clamping device has the first part 2a connecting with the output shaft 11 of the rotation motor 1 and first
Point 2a connection and the screw rod 2b coaxial with output shaft 11, the binding nut 2c being screwed on screw rod 2b.Binding nut 2c and first
The clamping zone of grinding wheel 3 is formed between the 2a of part.Grinding wheel has central through hole and the cylinder shape groove coaxial with central through hole.It will
Screw rod 2b pass through the central through hole, and by screw the binding nut 2c by the grinding wheel 3 be clamped in first part 2a and
Between binding nut 2c, the end of binding nut 2c and screw rod 2b are respectively positioned in the cylinder shape groove.
Further, for the ease of remote reconditioning operation, the tail portion of the rotation motor 1 is additionally provided with hand-held extension bar
4.The hand-held extension bar 4 is removably connect with the rotation motor 1.Maintenance is also easily removable while facilitating reconditioning.
According to live different situations, grinding wheel 3 be can be selected as spill sand that outer diameter is any size in 50mm, 60mm, 80mm
Wheel.So as to realize the reconditioning to each region of roll pass and the narrow position of guide groove.
The device can be such that the utilization rate of breaking-down roll improves.After coming into operation, roll founds slot-type using the time by original
Come 10 days or so, increase is used till now at 15 days or so, and 30% efficiency can be improved through counting.Roller consumption is reduced, is reduced
Roll changing time.Also greatly reduce the surface scratching of finished product to the reconditioning of narrow zone simultaneously.
