DETAILED DESCRIPTION

[0030] The following will be described in detail in combination with the accompanying drawings. Figures 1-2 The present application will be further described in detail.

[0031] The embodiment of the application discloses a roll torque compensation structure for an external grinding machine. Figure 1 Figure 2 The roll torque compensation structure for the external grinding machine is matched with a driving disc 1 of the external grinding machine, and comprises a compensation assembly 2 and a clamping assembly 3 for clamping a roll, the compensation assembly 2 comprises a sleeve 21, a first adjusting rod 22 and a second adjusting rod 23, the first adjusting rod 22 is arranged at one end of the sleeve 21, the second adjusting rod 23 is arranged at the other end of the sleeve 21, and the first adjusting rod 22 and the second adjusting rod 23 are both in threaded connection with the inner wall of the sleeve 21. The first adjusting rod 22 is connected with the driving disc 1, and the second adjusting rod 23 is connected with the clamping assembly 3. The adjustable first adjusting rod 22 and the second adjusting rod 23 facilitate the compensation assembly 2 to adapt to rolls of different sizes, meanwhile, the compensation assembly 2 is connected with the driving disc 1 and the clamping assembly 3, so that kinetic energy provided by the driving disc 1 can be more completely conducted to the roll, and the possibility of damage of the roll in the rotating process due to torque exceeding a set threshold is reduced.

[0032] In order to improve the connection stability between the first adjusting rod 22 and the driving disc 1, a limiting plate 11 is fixed on the driving disc 1, a plurality of first tooth grooves 111 are formed in the limiting plate 11, a limiting seat 4 is fixed on the first adjusting rod 22, and a plurality of second tooth grooves 41 matched with the first tooth grooves 111 are formed in the limiting seat 4. Figure 1 Figure 2 In order to facilitate the connection between the limiting seat 4 and the first adjusting rod 22, a support plate 221 is fixed on the first adjusting rod 22 and abuts against the limiting seat 4. A plurality of conducting rods 42 are fixed on the limiting seat 4, and each conducting rod 42 penetrates through the support plate 221.

[0033] The second tooth grooves 41 on the limiting seat 4 are matched with the first tooth grooves 111 at the corresponding positions of the limiting plate 11, which on one hand increases the contact area between the limiting seat 4 and the limiting plate 11, and on the other hand provides limiting for the limiting seat 4, thereby reducing the possibility of separation between the limiting seat 4 and the limiting plate 11 in the roll machining process. Meanwhile, the plurality of conducting rods 42 are arranged, so that the second adjusting rod 23 can rotate with the limiting seat 4, so that the driving disc 1 can more stably provide rotating kinetic energy for the compensation assembly 2, the clamping assembly 3 and the roll.

[0034] Each end of each conducting rod 42 away from the limiting seat 4 is arranged in an arc shape, so that the conducting rod 42 is not easy to cause damage to the support plate 221 in the process of penetrating through the support plate 221.

[0035] Each end of each conducting rod 42 away from the limiting seat 4 is arranged in an arc shape, so that the conducting rod 42 is not easy to cause damage to the support plate 221 in the process of penetrating through the support plate 221. Figure 2

[0036] In order to improve the connection stability between the first adjusting rod 22 and the driving disc 1, a limiting plate 11 is fixed on the driving disc 1, a plurality of first tooth grooves 111 are formed in the limiting plate 11, a limiting seat 4 is fixed on the first adjusting rod 22, and a plurality of second tooth grooves 41 matched with the first tooth grooves 111 are formed in the limiting seat 4. Figure 2 ​​​A plurality of spacers 5 are arranged between the limiting seat 4 and the sleeve 21. The spacers 5 close to the sleeve 21 abut against the sleeve 21, and the spacers 5 close to the limiting seat 4 abut against the limiting seat 4. The spacers 5 compensate the position between the limiting seat 4 and the sleeve 21, and improve the structural strength of the compensation assembly 2 as a whole, so that the compensation assembly 2 can more stably compensate the torque required during the rolling mill processing.

[0037] With reference to Figure 1 The clamping assembly 3 comprises two limiting frames 31 arranged oppositely and connected through a connecting rod 32. The connecting rod 32 is threadedly connected with a first fixing ring 33, and each limiting frame 31 corresponds to one first fixing ring 33. The first fixing ring 33 abuts against the limiting frame 31 at the corresponding position, and the second adjusting rod 23 is connected with the connecting rod 32 at the end away from the sleeve 21.

[0038] The worker abuts the two limiting frames 31 against the rolling mill, passes the connecting rod 32 through the two limiting frames 31, and installs the first fixing ring 33 on the connecting rod 32, so that the first fixing ring 33 abuts against the limiting frame 31 at the corresponding position. In this way, the installation between the clamping assembly 3 and the rolling mill is completed.

[0039] With reference to Figure 1 and Figure 2 In order to facilitate the fixation of the second adjusting rod 23 and the connecting rod 32, the end of the second adjusting rod 23 away from the sleeve 21 is provided with a fixing plate 231 abutting against the connecting rod 32, and the fixing plate 231 is fixed with a fixing column 232. The connecting rod 32 is provided with a fixing hole 321, and the fixing plate 231 passes through the fixing hole 321. The fixing plate 231 is connected with the connecting rod 32 through a connecting assembly 6.

[0040] The connecting assembly 6 comprises a connecting column 61 and a connecting plate 62. The connecting column 61 is fixed on the fixing plate 231, and the connecting plate 62 is slidingly connected on the second adjusting rod 23. The connecting column 61 and the fixing column 232 both pass through the connecting plate 62. The connecting column 61 and the fixing column 232 are both threadedly connected with a second fixing ring 63 abutting against the connecting plate 62.

[0041] The worker passes the fixing column 232 through the fixing hole 321, so that the fixing plate 231 abuts against the connecting rod 32. Then the worker moves the connecting plate 62, so that the fixing column 232 and the connecting column 61 pass through the connecting plate 62. After the connecting plate 62 abuts against the connecting rod 32, the worker installs the second fixing ring 63 on the connecting column 61 at the corresponding position and the fixing column 232 at the corresponding position, so that the connecting plate 62 abuts against the connecting rod 32. At this time, the connecting plate 62 cooperates with the fixing plate 231 to provide a limit for the second adjusting rod 23 and the connecting rod 32, and reduces the possibility of separation of the second adjusting rod 23 and the connecting rod 32.

[0042] The implementation principle of the roll torque compensation structure for the cylindrical grinding machine is that the adjustable first adjusting rod 22 and the second adjusting rod 23 are matched with the sleeve 21, so that the compensation assembly 2 is adapted to different types of rolls. And since the first adjusting rod 22 is connected with the driving disc 1, and the second adjusting rod 23 is connected with the clamping assembly 3, the driving disc 1 can more stably transmit the rotational kinetic energy to the roll, compensate the torque required during the processing of the roll, and reduce the possibility of damage of the roll due to excessive torque.

[0043] The above are preferred embodiments of the present application, and do not limit the protection scope of the present application, so that: any equivalent changes made according to the structure, shape, principle of the present application should be covered within the protection scope of the present application.
