[0002] A grinding machine is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinding machines use high-speed rotating grinding wheels for grinding, while a few use other abrasive tools such as oilstones, abrasive belts, and free abrasives for processing. Examples include honing machines, superfinishing machines, belt grinders, lapping machines, and polishing machines.

BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Figure 1 The utility model is a schematic diagram of the overall structure of an adjustable support device for offline static balance adjustment of a grinding wheel of a grinding machine. DETAILED DESCRIPTION

[0021] The following is a more detailed description of the adjustable support device for offline static balancing of a grinding wheel of the present invention, with reference to schematic diagrams. Preferred embodiments of the present invention are shown, and it should be understood that those skilled in the art may modify the present invention described herein while still achieving the advantageous effects of the present invention. Therefore, the following description should be understood as being generally known to those skilled in the art and not as limiting the present invention.

[0022] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description and claims. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0023] like Figure 1 As shown, an embodiment of the present invention proposes an adjustable support device for offline static balancing of a grinding wheel of a grinding machine, comprising a base 1, a support frame 2, a swing frame 3 and a balance bar 4.

[0024] Specifically, two support frames 2 are provided, and the two support frames 2 are fixedly mounted on the base 1 .

[0025] The center position of the bottom of the swing frame 3 is rotatably mounted on the support frame 2 , and adjustment screws 5 for adjusting the horizontal state of the swing frame 3 are installed at both ends of the swing frame 3 .

[0026] The balance bar 4 is arranged on the top of the swing frame 3, and the balance bar 4 is used to calibrate the static balance of the grinding wheel of the grinding machine.

[0027] In this embodiment, the swing frame 3 is rotatably mounted on the support frame 2 via a rotating shaft, the adjusting screw 5 is threadedly mounted on the swing frame 3 , and the bottom end of the adjusting screw 5 abuts against the support frame 2 .

[0028] When the adjustable support device needs to be horizontally adjusted, the adjustment screw 5 is rotated. Since the adjustment screw 5 is threadedly connected to the swing frame 3, during the rotation of the adjustment screw 5, the adjustment screw 5 moves along its length and abuts against the upper surface of the support. When the adjustment screws 5 at both ends of the swing frame 3 abut against the upper surface of the support, and the swing frame 3 support plane is horizontal, the adjustable support device is horizontally adjusted.

[0029] In order to ensure that the swing frame 3 maintains a stable horizontal support state after completing the horizontal adjustment, a locking nut 6 is threadedly installed on the adjustment screw 5, and the locking nut 6 is in contact with the upper surface of the swing frame 3.

[0030] Furthermore, nylon retaining rings 7 are provided at both ends of the balance bar 4 , and the nylon retaining rings 7 are used to position the balance bar 4 and prevent the balance bar 4 from sliding.

[0031] Specifically, the balance bar 4 is slidably set on the swing frame 3. Before the swing frame 3 is horizontally adjusted, the nylon retaining ring 7 is not installed. The horizontal adjustment personnel can judge whether there is a height difference between the two ends of the swing frame 3 (that is, whether it is horizontal) based on the sliding of the balance bar 4 on the swing frame 3, which is convenient for the horizontal adjustment personnel to perform adjustments.

[0032] When the horizontal adjustment of the swing frame 3 is completed, the nylon retaining rings 7 are inserted into the two ends of the balance bar 4. At this time, the nylon retaining rings 7 can effectively prevent the balance bar 4 from sliding off the swing frame 3.

[0033] Furthermore, a plurality of adjustable support seats are provided on the bottom surface of the base 1 , and the adjustable support seats are distributed on the bottom surface of the base 1 in a rectangular shape.

[0034] Specifically, the adjustable support seat includes a fixed wedge block 8, an adjusting wedge block 9 and an adjusting seat 10. The fixed wedge block 8 is fixedly mounted on the bottom surface of the base 1, and the adjusting wedge block 9 is mounted on the adjusting seat 10. The inclined surface of the adjusting wedge block 9 fits and slides in contact with the inclined surface of the fixed wedge block 8. A positioning groove 11 is vertically provided on the adjusting seat 10, and an adjusting bolt 12 is movably provided in the positioning groove 11, and the adjusting bolt 12 is threadedly connected to the fixed wedge block 8.

[0035] When the support height and level adjustment are required, tightening the adjustment bolt 12 causes the adjustment seat 10 to push the adjustment wedge 9. At this point, the inclined surface of the adjustment wedge 9 lifts the inclined surface of the fixed wedge 8, increasing the support height. When loosening the adjustment bolt 12, the inclined surface of the fixed wedge 8 pushes the adjustment wedge 9 and the adjustment seat 10 in a downward direction, lowering the support height. By adjusting the adjustable support seat in sequence according to the above method, the support height and level adjustment can be achieved. Combined with the horizontal adjustment of the swing frame 3, the horizontal adjustment of the adjustable support device can be achieved quickly and stably.

[0036] Compared with the prior art, the present invention has at least the following beneficial effects:

[0037] The utility model utilizes the rotation of the adjustment screw 5 to change the horizontality of the support plane of the swing frame 3, can quickly and conveniently realize the horizontal adjustment of the support plane of the swing frame 3, and then facilitates the static balance calibration of the grinding wheel of the grinder, and has the characteristics of simple structure and convenient operation.

[0038] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
