[0002] When a workpiece is being ground, most of the processing is carried out using a grinding machine. In actual production, when using a grinding machine to process a conical workpiece, the outer diameter is generally used as the main reference, and one end face is used as the auxiliary reference, and then the other end face is processed. When the workpiece needs to rotate, the main reference support point will rub against the rotating workpiece, and the generated frictional force mainly comes from the contact point between the main support and the product, and this contact point cannot be avoided. The generated frictional force will not only affect the surface quality of the product, but also make it inconvenient for the workpiece to rotate. Therefore, a device for supporting the outer diameter of a portable workpiece is needed. Summary of the Utility Model

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0025] Reference Figure 1-6 , a lightweight base surface grinding machine support device, including a support main body 1, and a bearing 7 for supporting a workpiece is arranged at the top of the support main body 1;

[0026] There are two bearings 7, and the distance between the two bearings 7 can be adjusted by a slider mechanism;

[0027] The support main body 1 is installed on the work loading table of the grinding machine through a base 2.

[0028] In a specific embodiment of the present utility model, the bearing 7 can adopt a high-precision bearing to improve the accuracy during support; by arranging two bearings 7 and setting the distance between the two bearings 7 to be adjustable, it can be used to support workpieces of different lengths, making the adaptability of this device stronger and capable of adapting to most usage scenarios; in some embodiments, the connection between the support main body 1 and the base 2 can be set to be adjustable to adjust the angle of the support main body 1, so that the two bearings 7 can support the taper of different tapered workpieces.

[0029] When the base 2 is installed on the work loading table, it is installed by using the conventional fixing method of bolts and nuts.

[0030] For key reference Figure 1 , this device is used in pairs, and two symmetrically arranged devices are used to jointly support the workpiece, that is, it is equivalent to using four bearings 7 to all fit the circumferential surface of the workpiece to provide a stable support effect.

[0031] An installation groove 8 is opened at one end of the top of the support main body 1, and this end of the support main body 1 is upwardly convex. The installation groove 8 is located at this convex position, and one of the bearings 7 is installed in the installation groove 8;

[0032] A support shaft is fixedly arranged in the installation groove 8, and the bearing 7 is installed on this support shaft. The bearing 7 and the support shaft can be in interference fit, and rely on the self-rotating effect of the bearing 7 to realize rotation along with the workpiece.

[0033] The slider mechanism includes a slider 6 and a chute 4 opened on the upper part of the support main body 1. The slider 6 is slidably arranged in the chute 4, and the other bearing 7 is installed on the upper part of the slider 6;

[0034] The opening position of the chute 4 is located at the top of the support main body 1 except for the convex position, that is, the outer end of the chute 4 is flush with the outer end of the support main body 1, and the inner end of the chute 4 stops at the side of the convex position. The lower part of the slider 6 is slidably arranged in the chute 4; the upper part of the slider 6 is U-shaped, and a support shaft is also fixedly arranged at this position of the slider 6. The other bearing 7 is installed on this support shaft, so that the other bearing 7 is located inside the U-shape of the slider 6, and the installation methods of the two bearings 7 are the same.

[0035] The slider mechanism further includes a first bolt 9 for limiting the slider 6. An upper portion of the front surface of the support body 1 is provided with a first straight notch 5. The first bolt 9 passes through the first straight notch 5 and is threadedly connected to the lower portion of the slider 6. A threaded hole matching the first bolt 9 is provided in the lower portion of the slider 6, and the opening of the threaded hole faces the direction of the first straight notch 5. When limiting the slider 6, after the first bolt 9 passes through the first straight notch 5, it is screwed into the threaded hole, and the head of the first bolt 9 clamps the support body 1 with the slider 6, and the friction force is used to limit the slider 6.

[0036] The connection between the support body 1 and the base 2 is detachable, and the height and angle of the support body 1 can be adjusted. In some embodiments, the upper vertical plate of the base 2 is inclined. When arranged in pairs, the distance between the tops of the vertical plates of the two bases 2 is greater than the distance between their bottoms, that is, the cross-sections of the vertical plates of the two bases 2 together form a trapezoid. By adjusting the height and angle of the support body 1, workpieces with different outer diameters and different tapers can be supported, making the adaptability of the device stronger. Specifically, since the vertical plate of the base 2 is inclined, when adjusting the height of the support body 1, the horizontal distance between the tops of the two support bodies 1 will be farther or closer, thereby changing the distance between the bearings 7 on different support bodies 1, and then adapting to workpieces with different outer diameters. At the same time, when adjusting the height, the angle of the support body 1 is also adaptively adjusted so that the two bearings 7 on the same support body 1 can adapt to the taper of the workpiece.

[0037] In some embodiments, chamfers are provided on both the protrusion of the support body 1 and the upper portion of the slider 6. The chamfer position can refer to Figure 1 , and the chamfers are located on the side where two sets of this device are close to each other, avoiding interference when the distance between the two support bodies 1 is too close or affecting the workpiece.

[0038] An arc-shaped groove 3 and a screw hole 12 are provided in the upper part of the base 2, and a second straight notch 10 is provided in the lower part of the support body 1. The support body 1 is connected to the base 2 by two second bolts 11. When connecting the support body 1 and the base 2, one of the second bolts 11 is passed through the second straight notch 10 and then screwed into the screw hole 12 to clamp the support body 1 and the base 2. Then, the other second bolt 11 is sequentially passed through the second straight notch 10 and the arc-shaped groove 3, and then the matching nut is screwed onto the second bolt 11 to clamp the support body 1 and the base 2, completing the connection between the support body 1 and the base 2; through the provided second straight notch 10, the height of the support body 1 can be adjusted. During adjustment, the relative position of the second bolt 11 in the second straight notch 10 is changed; through the provided arc-shaped groove 3, the angle of the support body 1 can be adjusted, that is, by changing the position of the second bolt 11 with a nut on the arc-shaped groove 3, the angle of the support body 1 can be adjusted.

[0039] Installation process: According to the length of the conical workpiece, the distance between the two bearings 7 on the same support body 1 is adjusted respectively, and then according to the taper of the conical workpiece, the angle of the support body 1 is adjusted so that the annular surfaces of the two bearings 7 on the same support body 1 can adapt to the taper of the conical workpiece. Then, the height of the support body 1 can be adjusted according to the outer diameter of the conical workpiece, so that the two pairs of this device can adapt to the outer diameter of the workpiece, so that the four bearings 7 can all hold against the workpiece, playing a role in stably supporting the workpiece and preventing one end of the workpiece from sinking under the action of gravity after being fixed; during the processing, when the workpiece needs to rotate, since the annular surface of the workpiece is in contact with the bearing 7, when the workpiece rotates, the bearing 7 can also rotate accordingly, thereby reducing the damage to the workpiece.
