[0018] In order to make the technical methods, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1 , 4 , 5, 6 and Figure 7As shown, in response to the problems in the prior art, the present invention provides a coating tool assembly suitable for different reaming shapes, including an equipment body 1, the positioning assembly 5 is installed on the outer wall of the equipment body 1, the interior of the positioning assembly 5 includes a fixed ring 51, a first electric push rod 52, a sliding ring 53, a connecting frame 54, a rotating shaft 55 and a second motor 56, the fixed ring 51 is fixedly installed on the outer wall of the equipment body 1, multiple groups of bases of the first electric push rods 52 are fixedly connected to the lower end of the fixed ring 51, the sliding ring 53 is slidably connected to the outer wall of the connecting tube 2, the upper end of the sliding ring 53 is fixedly connected to the output shafts of multiple groups of first electric push rods 52, the multiple groups of connecting frames 54 are fixedly installed on the outer wall of the sliding ring 53, the rotating shaft 55 is rotatably connected to the inside of the connecting frame 54, the output shaft of the second motor 56 is fixedly connected to one end of the rotating shaft 55, and the second motor 56 is fixedly installed on the connecting tube 2. On one side of the connecting frame 54, one end of the mounting box 61 is fixedly connected to the outer wall of the rotating shaft 55, and the reaming blade 62 is slidably connected to the inside of the mounting box 61. The second motor 56 drives the rotating shaft 55 to rotate to a maximum angle of 180 degrees in the forward direction and 30 degrees in the reverse direction. The reaming tool assembly 6 is fixedly installed on the outer wall of the rotating shaft 55. The interior of the reaming tool assembly 6 includes a mounting box 61, a reaming blade 62, a slide groove 63, a fixing frame 64 and a second electric push rod 65. Two groups of slide grooves 63 are opened inside the mounting box 61, and a group of fixing frames 64 are slidably connected in the slide grooves 63. A group of reaming blades 62 are placed inside the fixing frame 64. The reaming blade 62 and the fixing frame 64 are fixedly connected by bolts. The lower end of the fixing frame 64 is fixedly connected to the output shaft of the second electric push rod 65, and the second electric push rod 65 is fixedly installed inside the mounting box 61.

[0020] In the present invention, when it is necessary to expand the hole, the hole diameter is first expanded to a range that can accommodate the entire expansion tool assembly 6, and then the first electric push rod 52 is started, which will drive the sliding ring 53 to slide downward on the connecting tube 2. When the first electric push rod 52 is extended to the maximum position, the expansion tool assembly 6 will be located at the periphery of the tool 3. At this time, if a tapered hole needs to be processed, the second motor 56 needs to be started to reverse, which will drive the rotating shaft 55 to rotate in the opposite direction, and the rotating shaft 55 will drive the expansion tool assembly 6 to rotate as a whole, thereby changing the cutting angle of the expansion tool assembly 6 to adapt to the processing of the tapered hole. The staff can adapt to the size requirements of the tapered hole by changing the angle at which the second motor 56 drives the rotating shaft 55 to rotate; If it is necessary to process an inverted tapered hole, it is only necessary to start the second motor 56 in the forward direction, which will drive the rotating shaft 55 to rotate forward, and the rotating shaft 55 will drive the reaming tool assembly 6 to rotate as a whole, thereby changing the cutting angle of the reaming tool assembly 6, so as to achieve the processing of the inverted tapered hole. There is no need for the staff to manually adjust the angle of the reaming tool assembly 6. When the normal cylindrical hole needs to be expanded and the hole diameter expansion demand is large, it is only necessary to control the second electric push rod 65 to extend, which will control the fixed frame 64 to slide inside the slide groove 63, thereby driving the reaming blade 62 to extend outward, and the hole expansion demand is met by controlling the extension length of the reaming blade 62.

[0021] like Figure 2 as well as Figure 3 As shown, a group of chip removal components 4 are fixedly installed inside the equipment body 1, and the interior of the chip removal component 4 includes a barrier cover 41, a drill bit 42, a suction box 43, a mounting tube 44, a connecting tube 45, a dust collector 46, an air outlet pipe 47, a storage cylinder 48 and a first motor 49. The barrier cover 41 is fixedly installed at the lower end of the tool 3, and a plurality of notches are provided on the outer wall of the barrier cover 41. The first motor 49 is fixedly installed at the inner top end of the connecting cylinder 2, and the output shaft of the first motor 49 is fixedly connected to the upper end of the storage cylinder 48. The lower end of the storage cylinder 48 is fixedly connected to a group of dust collectors 46, and the dust collectors 46 are rotatably connected to the inner bottom plate of the connecting cylinder 2. A group of air outlet pipes 47 are fixedly connected to both sides of 46, and there is a gap between the air outlet pipes 47 and the connecting tube 2. When the air outlet pipe 47 rotates, the air outlet end at its upper end coincides with the air outlet opened at the upper end of the connecting tube 2. The first motor 49 drives the storage tube 48 to rotate at an angle of 35 degrees in the positive direction. The lower end of the vacuum cleaner 46 is fixedly connected to one end of the connecting pipe 45, and the other end of the connecting pipe 45 is fixedly connected to one end of the mounting pipe 44. The connecting pipe 45 is rotatably connected to the inside of the tool 3. A plurality of suction boxes 43 are fixedly connected to the outer wall of the mounting pipe 44. The suction boxes 43 are fixedly installed inside the drill bit 42, and the drill bit 42 and the mounting pipe 44 are fixedly connected.

[0022] In the present invention, after the first motor 49 is started to rotate, the first motor 49 will drive the storage tube 48 to rotate 30 degrees, and the vacuum cleaner 46 and the drill bit 42 will also rotate 30 degrees driven by the storage tube 48. At this time, the feeding port of the suction box 43 is just aligned with the slot opened on the barrier cover 41. Then the vacuum cleaner 46 is started again, and the debris generated by the hole expansion will be sucked into the storage tube 48 through the connecting pipe 45 through the suction box 43 for storage, which is convenient for subsequent staff to clean it up, and can prevent the processed debris from remaining in the hole when processing the tapered hole or the inverted tapered hole, thereby aggravating the wear of the reaming blade 62, thereby effectively improving the service life and work efficiency of the reaming blade 62.

[0023] Working principle: First, fix the device body 1 as a whole on the punching device, start the device to drive the device body 1 to rotate for punching. When the hole needs to be enlarged, first expand the hole diameter to a range that can accommodate the entire enlarging tool assembly 6, and then start the first electric push rod 52, which will drive the sliding ring 53 to slide downward on the connecting tube 2. When the first electric push rod 52 extends to the maximum position, the enlarging tool assembly 6 will be located on the periphery of the tool 3. At this time, if a tapered hole needs to be processed, the second motor 56 needs to be started to reverse, which will drive the rotating shaft 55 to rotate in the opposite direction, and the rotating shaft 55 will drive the enlarging tool assembly 6 to rotate as a whole, thereby changing the cutting angle of the enlarging tool assembly 6 to adapt to the processing of the tapered hole. The staff can adapt to the size requirements of the tapered hole by changing the angle at which the second motor 56 drives the rotating shaft 55 to rotate. If an inverted tapered hole needs to be processed, only the second motor 56 needs to be started to rotate forward. The principle of driving the parts to rotate is consistent with the above-mentioned reversal, only the rotation direction is different, so as to achieve the processing of the inverted tapered hole, without the need for the staff to manually adjust the enlarging tool assembly The angle of the component 6 is adjusted to improve the working efficiency. When the normal cylindrical hole needs to be expanded and the expansion demand of the hole diameter is large, it is only necessary to control the extension of the second electric push rod 65, which will control the fixing frame 64 to slide inside the slide groove 63, thereby driving the reaming blade 62 to extend outward. By controlling the extension length of the reaming blade 62 to meet the reaming demand, while the reaming work is being carried out, the first motor 49 can be started to rotate, and the first motor 49 will drive the storage cylinder 48 to rotate 30 degrees, while the vacuum cleaner 46, the connecting pipe 45, the mounting pipe 44, the suction box 43 and the like are rotated. The drill bit 42 will also rotate 30 degrees driven by the storage tube 48. At this time, the inlet of the suction box 43 is just aligned with the notch opened on the barrier cover 41. After the adjustment is completed, the vacuum cleaner 46 is started. The vacuum cleaner 46 will suck the debris generated by the expansion through the suction box 43 through the mounting tube 44 and the connecting tube 45 into the storage tube 48 for storage, which is convenient for subsequent staff to clean it up. It can also prevent the processing debris from remaining inside the hole when processing the tapered hole or the inverted tapered hole, thereby aggravating the wear of the expansion blade 62 and reducing its work efficiency.
