[0034] In one embodiment of this utility model, such as Figures 1-5 As shown, a tapping fixture for a rotating shaft cover is provided, comprising a base frame 1, a base 2, a clamping cylinder 3, a lower clamping plate 4, and an upper clamping plate 5.

[0035] The base frame 1 provides support for the entire fixture, and the base 2 is fixed to the base frame 1 with bolts. The base 2 is I-shaped, which ensures the strength of the base 2 while reducing its weight. Multiple mounting holes 21 are evenly distributed on the base 2 for connecting with the base frame 1; at the same time, the base 2 is also provided with an arc-shaped clearance groove 22 to avoid interference with the tapping equipment during processing.

[0036] Three clamping cylinders 3 are provided and are evenly fixed on the base 2. Each clamping cylinder 3 includes a clamping cylinder body 31 and a clamping piston rod 32. The clamping cylinder body 31 is fixed to the base 2 by bolts. The clamping piston rod 32 can reciprocate within the clamping cylinder body 31, and one end of it passes through the base 2 and is fixedly connected to the upper clamping plate 5.

[0037] The lower clamping plate 4 is fixed to the base 2 by bolts, and multiple lower positioning seats 6 are evenly distributed on it. Adjacent lower positioning seats 6 are parallel and spaced apart. Each lower positioning seat 6 is provided with a lower positioning groove 61 for placing the rotating shaft cover 7.

[0038] The upper clamping plate 5 is located on the top side of the lower clamping plate 4, and a limiting protrusion 8 is provided at its bottom corresponding to the position of the lower positioning groove 61. The limiting protrusion 8 can be installed in the lower positioning groove 61. A limiting shaft hole 81 is provided on one side of the limiting protrusion 8. The limiting shaft hole 81 is located above the lower positioning groove 61 and is used to position the shaft part of the rotating shaft cover 7.

[0039] The rotary cover tapping fixture provided in this application can accurately position the rotary cover 7 by cooperating with the lower positioning groove 61 and the limiting protrusion 8, as well as setting the limiting shaft hole 81, thus ensuring the accuracy of the tapping position. The three evenly distributed clamping cylinders 3 provide balanced clamping force, avoiding the problem of deformation of the rotary cover 7 caused by uneven clamping force in traditional fixtures.

[0040] To ensure that the clamping piston rod 32 of the clamping cylinder 3 can pass smoothly through the lower clamping plate 4 and the upper clamping plate 5, the lower clamping plate 4 is provided with a lower clearance hole 41 in the middle, through which the clamping piston rod 32 of one of the clamping cylinders 3 passes; the upper clamping plate 5 is provided with an upper clearance hole 51 at the top, through which all the clamping piston rods 32 of the clamping cylinders 3 pass and are fixedly connected to the upper clamping plate 5.

[0041] In addition, multiple guide rods 9 are provided between the base 2 and the upper clamping plate 5. One end of the guide rod 9 is fixed to the base 2, and the other end is movably inserted through the upper clamping plate 5. The function of the guide rods 9 is to ensure the smooth movement of the upper clamping plate 5 during the clamping process, avoid tilting or shaking, thereby improving the clamping accuracy and stability.

[0042] Work process:

[0043] When using this fixture for tapping the shaft cover, first place the shaft cover 7 in the lower positioning groove 61 of the lower positioning seat 6, aligning the shaft portion of the shaft cover 7 with the limiting shaft hole 81. Then, activate the clamping cylinder 3, causing the clamping piston rod 32 to move downwards, which in turn moves the upper clamping plate 5 downwards, allowing the limiting protrusion 8 to insert into the lower positioning groove 61, thus firmly clamping the shaft cover 7 between the lower clamping plate 4 and the upper clamping plate 5. At this point, the position of the shaft cover 7 is precisely positioned, and tapping can be performed. After processing, the clamping piston rod 32 of the clamping cylinder 3 moves upwards, causing the upper clamping plate 5 to move upwards, releasing the clamp on the shaft cover 7, and the processed shaft cover 7 can then be removed.

[0044] The rotary cover tapping fixture provided in this application can accurately position the rotary cover 7 by cooperating with the lower positioning groove 61 and the limiting protrusion 8, as well as setting the limiting shaft hole 81, thus ensuring the accuracy of the tapping position. The three evenly distributed clamping cylinders 3 provide balanced clamping force, avoiding the problem of deformation of the rotary cover 7 caused by uneven clamping force in traditional fixtures.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
