Detailed implementation manners

[0021] Since there are many types of rolls to be machined, there are also many types of corresponding center rests. Therefore, when grinding different types of rolls, it is necessary to frequently hoist and replace the center rest.

[0022] In the prior art, when the grinding object of the numerically controlled roll grinder is switched from the work roll to the pinch roll in the current grinding operation, the original work roll center rest needs to be removed, and then the pinch roll center rest is installed. After the pinch roll is ground, the pinch roll center rest is removed again. Because when preparing to grind the work roll, the pinch roll center rest must be removed.

[0023] Therefore, for the repeated operation of frequently hoisting and replacing the center rest as described above, when it is necessary to grind a small batch of pinch rolls with many types, the disadvantages will be more prominent.

[0024] To solve the above problems, this embodiment provides a combined center rest for a numerically controlled roll grinder. Please refer to Figure 1 which includes a center rest base 100, a work roll center rest 200, and a pinch roll center rest 300. When the combined center rest is applied, it needs to be installed on the tailstock side and the headstock side of the numerically controlled roll grinder respectively.

[0025] Specifically, the center rest base 100 is provided with a first installation position and a second installation position. The work roll center rest 200 is detachably installed at the first installation position of the center rest base 100, and the work roll to be ground is supported by the work roll center rest 200. The pinch roll center rest 300 is detachably installed at the second installation position of the center rest base 100, and the pinch roll to be ground is supported by the pinch roll center rest 300. When the numerically controlled roll grinder is installed on the tailstock side and the headstock side respectively, the work roll and the pinch roll can be placed on the combined center rest at the same time, and the work roll and the pinch roll are staggered from each other.

[0026] In the case where the work roll was ground previously and the pinch roll needs to be ground this time, there is no need to disassemble the work roll steady rest 200. Instead, the corresponding pinch roll steady rest 300 can be directly installed on the steady rest base 100 to achieve rapid tooling change and smoothly carry out the pinch roll grinding operation. After grinding is completed, the pinch roll steady rest 300 is lifted away, and the grinding of the work roll can be immediately resumed.

[0027] With this device, a single base can be commonly used for the grinding functions of both the work roll and the pinch roll with a box, reducing the replacement of the steady rest, reducing the workload of lifting the pinch roll steady rest 300, reducing the frequency of replacement and lifting, increasing the switching speed between different operations, and improving the on-site operation efficiency.

[0028] This device can not only complete the quick replacement of the pinch roll steady rest 300 but also quickly resume the grinding of the original work roll, effectively reducing the labor intensity and effectively increasing the operating rate of the grinding machine.

[0029] In some embodiments, the steady rest base 100 is configured to be installed on a pair of guide rails of a numerically controlled roll grinder. The guide rails are provided with guide grooves, and the bottom of the steady rest base 100 is provided with guide members that cooperate with the guide grooves. The steady rest base 100 can move along the guide grooves under the condition that the steady rest base 100 is not fixedly connected to the guide rails. After the steady rest base 100 moves to a preset position, the steady rest base 100 is then fixed to the guide rails to achieve the installation of the steady rest base 100 in the numerically controlled roll grinder.

[0030] In some embodiments, please refer to Figure 2 , the work roll steady rest 200, the U1 axis clamping plate 20, and the steady rest base 100 are connected in sequence. The work roll steady rest 200 is installed on the U1 axis clamping plate 20, and the U1 axis clamping plate 20 is installed on the steady rest base 100. The U1 axis clamping plate 20 is an existing structure of the numerically controlled roll grinder, and the relative positions of the U1 axis clamping plate 20 and the steady rest base 100 can be adjusted, thereby adjusting the orientation of the work roll installed on the work roll steady rest 200 to square the work roll.

[0031] In some embodiments, please refer to Figure 2 , the work roll steady rest 200 includes a first frame body 210 and a bearing pad 220 connected to the first frame body 210. The first frame body 210, the U1 axis clamping plate 20, and the steady rest base 100 are connected in sequence. The work roll to be ground is supported by the bearing pad 220. Bearing pads 220 of different specifications are provided, and the grinding of rolls with different roll diameters is achieved by replacing the bearing pads 220.

[0032] In some embodiments, please refer to Figure 3, the pinch roll center frame 300 includes a second frame body 310, a bearing seat height compensation cushion plate 320, a bearing seat width compensation cushion block 330, and a locking bolt 340. The second frame body 310 is detachably installed at the second installation position of the center frame base 100. The bearing seat height compensation cushion plate 320 is detachably installed in the second frame body 310, specifically by means of bolt connection. The bearing seat width compensation cushion block 330 is detachably installed on one side of the top of the second frame body 310, and the locking bolt 340 is horizontally installed on the other side of the top of the second frame body 310. When the bearing seat of the pinch roll is placed on the second frame body 310, the locking bolt 340 presses the bearing seat of the pinch roll against the bearing seat width compensation cushion block 330.

[0033] The pinch roll center frame 300 is equipped with bearing seat height compensation cushion plates 320 and bearing seat width compensation cushion blocks 330 of different specifications. According to the dimensions of the pinch roll and its bearing seat, the pinch roll center frame 300 is designed, and different specifications of bearing seat width compensation cushion blocks 330 and bearing seat height compensation cushion plates 320 are combined to reduce the types of the frame bodies of the pinch roll center frame 300.

[0034] Through the lightweight and miniaturized bearing seat width compensation cushion block 330 and bearing seat height compensation cushion plate 320, the number of the second frame bodies 310 is reduced by half after integration, reducing the manufacturing cost of the second frame body 310 by about 40%. By replacing the second frame body 310 and the bearing seat width compensation cushion block 330 and the bearing seat height compensation cushion plate 320, grinding of different types of pinch rolls is achieved.

[0035] In some embodiments, the material of the bearing seat height compensation cushion plate 320 is nylon, and the material of the bearing seat width compensation cushion block 330 can also be nylon, so that the compensation cushion plate has the advantage of light weight and meets the support requirements of the pinch roll. Thus, manual handling can be easily completed.

[0036] Although the preferred embodiments of the present invention have been described, those skilled in the art can make additional changes and modifications to these embodiments once they know the basic creative concept. Therefore, the appended claims are intended to be construed to include the preferred embodiments and all changes and modifications falling within the scope of the present invention.

[0037] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalent technologies, the present invention is also intended to include these modifications and variations.
