The pre-fixing component 5 includes: a slide groove 50, a slider 51, a fixing block 52, a spring 53, a clamping block 54, a slope 1 55, a slope 2 56, and a mounting groove 57.

[0022] The slide groove 50 is provided at the bottom of the clamping seat chuck body 1, and a slider 51 is slidably connected to the inner wall of the slide groove 50. A fixing block 52 is fixed to the bottom of the slider 51, and a spring 53 is fixed to the surface of the slider 51. The end of the spring 53 away from the slider 51 is fixed to the inner wall of the slide groove 50. A clamping block 54 is fixed to the side of the fixing block 52 away from the center of the clamping seat chuck body 1. The side of the clamping block 54 away from the clamping seat chuck body 1 is set as an inclined surface 1 55, and the side of the clamping block 54 away from the inclined surface 1 55 is provided with an inclined surface 2 56. A mounting groove 57 is provided on the surface of the mounting platform 2, and a limiting groove 58 is provided on the inner side of the mounting groove 57. The inclined surface 55 of the clamping block 54 contacts the surface of the mounting platform 2, driving the fixing block 52 to move close to the center of the circle of the clamping chuck body 1. When the bottom of the clamping chuck body 1 is in contact with the surface of the mounting platform 2, the clamping chuck body 1 is rotated, and the spring 53 drives the clamping block 54 to enter the limiting groove 58, thereby preliminarily stabilizing the clamping chuck body 1 and the mounting platform 2, and at the same time, the mounting hole 1 3 is parallel to the mounting hole 2 4.

[0023] The positioning assembly 6 includes a positioning plate 60, which is fixed on the surface of the clamp-type chuck body 1. A positioning groove 61 is opened on the surface of the mounting table 2. The positioning plate 60 is placed in the positioning groove 61. There is no need for personnel to accurately locate the positions of the mounting holes 1 3 and 2 4, thereby improving the installation efficiency.

[0024] There are four groups of slide grooves 50, sliders 51, fixed blocks 52, springs 53, and clamping blocks 54, and the four groups of slide grooves 50, sliders 51, fixed blocks 52, springs 53, and clamping blocks 54 are all arranged in a circular array with the center of the circle of the clamp-type chuck body 1 as the axis, thereby increasing the stability of the installation between the clamp-type chuck body 1 and the mounting platform 2. The surface of the clamp-type chuck body 1 is provided with a mounting hole 1 3, and the surface of the mounting platform 2 is provided with a mounting hole 2 4, which is convenient for personnel to install bolts. The fixed block 52 is arranged in an arc shape, and no motion interference will occur when the clamp-type chuck body 1 is rotated. The clamping block 54 is consistent in shape with the limiting groove 58, so that the clamping block 54 can completely enter the limiting groove 58 for limiting.

There is no need for personnel to accurately locate the positions of the mounting holes 1 3 and 2 4, thereby improving the installation efficiency. At this time, the surface of the inclined surface 1 55 of the clamping block 54 will contact the surface of the mounting platform 2, thereby driving the fixing block 52 to move close to the center of the clamping chuck body 1. When the bottom of the clamping chuck body 1 fits the surface of the mounting platform 2, the personnel can rotate the clamping chuck body 1. When the position of the clamping block 54 is parallel to the limiting groove 58, the spring 53 will drive the clamping block 54 to enter the limiting groove 58, thereby preliminarily stabilizing the clamping chuck body 1 and the mounting platform 2. At the same time, the mounting hole 1 3 is parallel to the mounting hole 2 4, so there is no need for personnel to hold the clamping chuck body 1 all the time. The bolts can be tightened at this time, and there will be no deviation that affects the installation efficiency, which is convenient for personnel to install. When the clamping chuck body 1 needs to be inspected and repaired, the bolts are removed at this time, and the clamping chuck body 1 is rotated so that the inclined surface 2 56 of the clamping block 54 contacts the inner wall of the limiting groove 58. At this time, the clamping block 54 drives the fixing block 52 to move close to the side of the center of the clamping chuck body 1 again, so that the clamping block 54 is separated from the limiting groove 58. At this time, the personnel can separate the clamping chuck body 1 and the mounting table 2, which is convenient for personnel to disassemble and inspect.

[0026] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention.
