[0002] Roller grinder is a special machine tool used for grinding the surface of rolls. It is mainly used for the maintenance and processing of rolls in industries such as steel, nonferrous metals, and aluminum. The quality of the roll surface directly affects the quality and production efficiency of metal materials such as steel, so roll grinders play an important role in industrial production. In the application of roll grinders, some key components, such as chucks, bearings, and couplings, need to have high precision and stability to ensure the working quality of the entire machine. In addition, the chuck and coupling will sag due to their own gravity, causing damage to the equipment, so a support device is required for support.

[0003] At present, in the operation process, when grinding roller workpieces of different diameters and lengths, the small diameter roller is placed eccentrically on the headstock spindle so that the grinding wheel can grind to the roller surface. In this way, the universal coupling will have yaw and telescopic movement, while the traditional support device for supporting the chuck and the coupling is fixed. Therefore, when facing the above-mentioned rollers of different diameters and lengths, the fixed support device cannot move, so the support effect is not ideal, which will cause equipment damage for a long time and affect the processing accuracy.

DETAILED DESCRIPTION

[0021] Reference Figures 1-2 , is the first embodiment of the utility model, which provides an adjustment auxiliary support device, which is arranged on the head frame, and the head frame includes a bearing seat, and a head frame main shaft arranged in the bearing seat, and a driving source is arranged at one end of the head frame main shaft, and the driving source is generally a motor driving the main shaft to rotate; specifically, the adjustment auxiliary support device includes: a fixed support 300 arranged on the head frame and located below the head frame main shaft, and a rotatable adjustment component 400 is arranged on the fixed support 300. In this embodiment, the rotatable installation can be realized in the following form: a connecting support is clamped on the fixed support 300, and a rotating shaft is arranged on the connecting support, and the adjustment component is rotatably connected with the rotating shaft to realize the hinge connection between the adjustment component 400 and the fixed support 300. A support component 500 is arranged at the output end of the adjustment component 400. The support component 500 in this embodiment has a lifting function, so the support component 500 has a degree of freedom in the vertical direction. In order to realize the degree of freedom of the support component 500 in the horizontal direction, the adjustment component 400 in this embodiment has a moving function. In other words, by driving the adjustment assembly 400 to move horizontally and / or telescopically, the support assembly 400 moves horizontally to achieve the desired horizontal positioning.

[0022] Correspondingly, a mounting piece is arranged on the main shaft of the head frame, and a fixing part is arranged at the end of the mounting piece, wherein the fixing part is used to fix the object to be supported. In order to make the position of the fixing part correspond to the position of the supporting assembly and achieve the supporting effect, the mounting piece also has a telescopic function.

[0023] Preferably, two sets of slide rails may be installed in the adjustment assembly 400 and the support assembly 500 in the horizontal and vertical directions instead.

[0024] In a further embodiment, the mounting member in this embodiment is a universal coupling 100 disposed at the free end of the head frame main shaft, and the required length adjustment is achieved through the joints of the universal coupling 100, that is, the contraction is achieved. The fixed part is a four-jaw chuck 200 fixed at the end of the universal coupling, and the support assembly is used to support the four-jaw chuck 200. The four-jaw chuck 200 is an existing technology for clamping and will not be described in detail. The further support assembly is used to support the bottom of the four-jaw chuck 200 in this embodiment to prevent the four-jaw chuck 200, the universal coupling 200 and other assembled parts from sagging due to their own weight, thereby extending the service life of the equipment.

[0025] Preferably, when facing workpieces of different diameters, the general operation process is to eccentric the four-jaw chuck 200, and at this time, only the adjustment component 400 needs to be moved horizontally to achieve the corresponding position of the support component 500 and the four-jaw chuck 200. When facing workpieces of different lengths, the universal coupling 100 will be telescopic with a certain amount of telescopic movement. At this time, it is necessary to adjust the telescopic movement of the adjustment component 400 to achieve the corresponding position of the support component 500 and the four-jaw chuck 200. When the positions correspond, the four-jaw chuck 200 is limited by the support component 500, and the whole process can be manually operated. Combined with the above, the head frame spindle drives the universal coupling 100 and the four-jaw chuck 200 to rotate, realizing the processing of the roller.

[0026] Furthermore, the adjustment assembly 400 in this embodiment includes: a first connecting rod 401 and a second connecting rod 402, wherein one end of the first connecting rod 401 is hingedly mounted on the fixed support 300. The second connecting rod 402 is hingedly connected to the other end of the first connecting rod 401. In other words, the overall length of the adjustment assembly 400 is adjusted by controlling the angle between the first connecting rod 401 and the second connecting rod 402, thereby adjusting the horizontal position of the support assembly 500. It should be noted that the number of connecting rods can be selected according to actual conditions, and they can be hinged to each other.

[0027] It should be noted that the horizontal or telescopic movement of the support assembly 500 can be achieved by adjusting the angles of the first and second connecting rods; the support block 502 is in direct contact with the four-jaw chuck 200, and the contact surface between the support block 502 and the four-jaw chuck 200 is set to an arc shape so that the shapes of the two are adapted to each other. A card slot can also be set on the support block 502, and a card block can be set on the four-jaw chuck 200, and the card slot and the card block are adapted to further stabilize the equipment.

[0028] Furthermore, the adjustment assembly 400 includes a first connecting rod 401 rotatably disposed at one end of the fixing support 300 , and a second connecting rod 402 rotatably disposed at the other end of the first connecting rod 401 .

[0029] Furthermore, the support assembly 500 includes a telescopic assembly 501 which is transmission-disposed at the end of the second connecting rod 402 , and a support block 502 which is disposed at one end of the telescopic assembly 501 close to the four-jaw chuck 200 .

[0030] Furthermore, a threaded hole is formed at the end of the second connecting rod 402; the telescopic assembly 501 includes: an adjusting screw 501a disposed in the threaded hole; and the supporting block 502 is connected to the top of the adjusting screw 501a.

[0031] It should be noted that the height of the support block 502 is adjusted by rotating the adjustment screw 501 a to achieve a supporting effect.

[0032] Furthermore, a thrust ball bearing 502a is disposed in the support block 502; the thrust ball bearing 502a is connected to the adjustment screw 501a.

[0033] It should be noted that the above-mentioned middle support block 502 is in direct contact with the four-jaw chuck 200. When in contact, there will be friction problems, which will make it difficult to rotate when continuing to adjust the height. Therefore, in order to save effort and improve the support accuracy, a thrust ball bearing 502a is set to ensure that the rotation of the adjustment screw 501a is effortless and can also improve the support accuracy.

[0034] Furthermore, a hand wheel dial 501b is provided at the end of the adjusting screw 501a.

[0035] It should be noted that in the prior art, a square head is generally provided at the end of the adjusting screw rod 501a, while the present invention adopts a hand wheel turntable 501b, which is convenient for operators to operate.

[0036] The working principle of the utility model is as follows: first, the workpiece is placed in the four-jaw chuck 200 to achieve positioning, and according to the position of the four-jaw chuck 200, the first connecting rod 401 and the second connecting rod 402 are adjusted, and after the support block 502 is adjusted to correspond to the position of the four-jaw chuck 200, the handwheel turntable 501b is rotated to make the adjustment screw 501a adjust the height of the support block 502 until it supports the four-jaw chuck 200 to achieve limit positioning, thereby preventing the four-jaw chuck 200, the universal coupling 200 and other assembled parts from sagging due to their own weight, thereby extending the service life of the equipment.

[0037] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
