Detailed Description
The present invention will now be described in detail with reference to the drawings, which are provided for illustrative and explanatory purposes only and should not be construed as limiting the scope of the present invention in any way.
The utility model provides an adjusting device for a grinding tool of an internal thread grinding machine, which comprises a main shaft fixing device, an adjusting mechanism 7 and an internal thread grinding base 1;
the main shaft fixing device is fixed on the internal thread mill base 1, and the adjusting mechanism 7 is fixed on the main shaft fixing device.
The spindle fixing device comprises a spindle base 2, a spindle adjusting seat 3 which is concentrically fixed with the spindle base 2 through a positioning pin 8 and is arranged on one side face of the spindle base 2, a spindle seat 4 fixed on the other side face of the spindle adjusting seat 3, an electric spindle 5 which is arranged in a through hole of the spindle seat 4, and a grinding wheel fixing shaft 6 which is fixed on the electric spindle 5 and is coaxially arranged with the electric spindle 5, wherein a grinding wheel for grinding a workpiece is fixed at the end of the grinding wheel fixing shaft 6.
The main shaft fixing device is also provided with a positioning pin 8 for fixing the main shaft base 2 and the main shaft adjusting seat 3; the central position of the positioning pin 8 and the central position of the workpiece are at the same central height. The workpiece is positioned opposite the spindle fixture (the workpiece is not shown in the figures). The spindle seat 4, the electric spindle 5 and the grinding wheel fixing shaft 6 are arranged at the same central height.
By the arrangement of the structure, when the main shaft adjusting seat 3 moves on the main shaft base 2, the position of the positioning pin 8 is unchanged, because the positioning pin 8 and the central position of a workpiece (namely a nut needing grinding internal threads) are at the same central height, and as long as the central height is unchanged, the angle cannot deviate during grinding.
The adjusting mechanism 7 is fixed on the top of the spindle base 2.
By the arrangement of the structure, the main shaft adjusting seat 3 can be attached to the vertical plane of the main shaft base 2 to slide up and down, and horizontal deviation and vertical deviation in the main shaft adjusting process cannot occur.
In this embodiment, preferably, the spindle base 2 is further provided with a spindle slide rail, and the spindle slide rail is arc-shaped.
The structure is arranged, so that the main shaft adjusting seat 3 can circumferentially slide on the main shaft base 2 along the main shaft slide rail by taking the positioning pin 8 as the center of a circle.
Preferably, in this embodiment, two main shaft slide rails are arranged in parallel.
By adopting the structure, the sliding of the main shaft adjusting seat 3 on the main shaft base 2 is more stable, and the deviation can not occur.
In this embodiment, preferably, the adjusting mechanism 7 further includes an adjusting screw 71, an adjusting nut 72, an adjusting seat 73, and an adjusting seat connecting member 74;
the adjusting seat 73 is fixed on the top of the spindle base 2, and the adjusting seat connecting piece 74 is connected with the adjusting seat 73 and the adjusting nut 72; one end of the adjusting screw 71 is fixedly connected with the main shaft adjusting seat 3 through the adjusting nut 72, and the other end is fixedly connected with the adjusting seat connecting piece 74.
The above structure is provided, so that the adjusting mechanism 7 can adjust and control the position of the spindle adjusting seat 3 on the spindle base 2.
Preferably, in this embodiment, the internally threaded grinding base 1 includes an upper base 11 and a lower base 12, and the upper base 11 and the lower base 12 are matched.
In the present embodiment, preferably, the upper base 11 and the lower base 12 are matched by a sliding rail.
The above-described structure is provided to allow the upper base 11 and the grinding wheel fixing device provided on the upper base 11 to displace together with the upper base 11 relative to the lower base 12.
The working principle is as follows: when the grinding wheel is required to grind and mill a workpiece, the upper base 11 and the lower base 12 can control the displacement of the upper grinding wheel fixing device to approach the workpiece. The electric spindle 5 drives the grinding wheel to rotate, and the grinding wheel grinds the threads inside the workpiece (namely the nut). The spindle adjusting seat 3 needs to be adjusted in position because the threads are tapered. The adjusting mechanism 7 can adjust the position of the spindle adjusting seat 3 for fixing the electric spindle 5 on the spindle base 2, so as to be matched with milling at different angles. The center position of the positioning pin 8 and the center position of the workpiece are at the same center height, so that the grinding angle of the internal thread of the workpiece does not deviate as long as the center height of the positioning pin 8 is unchanged.
It should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of describing the present invention and simplifying the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus should not be construed as limiting the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
