[0023] For this specific embodiment, the clamping cylinder 102 is fixedly connected to the main board 101 and is located on the side of the main board 101. The pressure plate 103 is fixedly connected to the clamping cylinder 102 and is located on the top of the clamping cylinder 102. The centering sleeve 104 is arranged on the side of the main board 101 close to the pressure plate 103. The cylinder body to be processed is installed on the centering sleeve 104 of the main board 101, and the clamping cylinder 102 is started to push the pressure plate 103 to press the cylinder body, thereby fixing the position of the cylinder body. The connection method and use method of the main board 101, the clamping cylinder 102, the pressure plate 103 and the centering sleeve 104 are detailed in the disclosed Chinese patent CN205325275U, which is not within the protection scope of this application and will not be repeated here.

[0024] The four-axis machine tool 106 is fixedly connected to the main board 101 and is located on one side of the main board 101. The slide rail 107 is fixedly connected to the four-axis machine tool 106 and is located on one side of the four-axis machine tool 106. The slide plate 108 is fixedly connected to the four-axis machine tool 106 and is located on one side of the four-axis machine tool 106. The slide plate 108 is slidably connected to the slide rail 107 and is located on one side of the slide rail 107.

The connecting strip 112 is fixedly connected to the fixed frame 110 and located on a side of the fixed frame 110 close to the transparent plate 111. When the cylinder body needs to be processed, the operator first slides the slide plate 108 to drive the fixed frame 110 to slide, and unfolds the four-axis machine tool 106 to facilitate the staff to place the cylinder body on the main board 101. At this time, the staff places the bottom claw of the cylinder body on the centering sleeve 104 in the mounting hole of the main board 101. The clamping oil cylinder 102 is started to push the pressing plate 103 to move and hold the cylinder body against the cylinder body so that the position of the cylinder body is fixed. After the cylinder body is placed, the staff slides the slide plate 108 again to move the slide plate 108 in the slide rail 107, driving the fixed frame 110 to move, and then closing the four-axis machine tool 106. At this time, the staff can start the four-axis machine tool 106 to process the cylinder body on the main board 101.

The operating box 115 is fixedly connected to the mounting frame 114 and is located on one side of the mounting frame 114. After the cylinder body is clamped and fixed, and the four-axis machine tool 106 is closed, the staff can rotate the rotating frame 113 according to the feel of use, and drive the operating box 115 on the mounting frame 114 to move to a position convenient for the staff to use, and by inputting processing instructions on the operating box 115, the processing components in the four-axis machine tool 106 can process the cylinder body on the main board 101.

[0026] Again, the base plate 116 is fixedly connected to the four-axis machine tool 106 and is located at the bottom of the four-axis machine tool 106. The pull ring 117 is fixedly connected to the fixed frame 110 and is located on one side of the fixed frame 110. The base plate 116 is installed at the bottom of the four-axis machine tool 106, which can facilitate the staff to place the cylinder body on the main board 101, avoiding the need for the staff to bend over to place it, and by holding the pull ring 117, the fixed frame 110 can be driven to move.

[0027] The present embodiment describes a bottom claw positioning and clamping device for four-axis machining of a cylinder body. When the cylinder body needs to be machined, the operator first holds the pull ring 117 to drive the slide plate 108 to move, and the fixed frame 110 slides accordingly, and the four-axis machine tool 106 is unfolded, so that the staff can place the cylinder body on the main board 101 conveniently. At this time, the staff places the bottom claw of the cylinder body on the centering sleeve 104 in the mounting hole of the main board 101, and starts the clamping cylinder 102 to push the pressing plate 103 to move, and hold the cylinder body against the position of the cylinder body. After completing the placement of the cylinder body, the staff holds the pull ring 117 again to drive the slide plate 108 to move, so that the slide plate 108 moves in the slide rail 107, and drives the fixed frame 110 to move, and then the cylinder body is fixed. The four-axis machine tool 106 is closed. At this time, the staff can start the four-axis machine tool 106 to process the cylinder body on the main board 101. At the same time, the staff can check the processing status of the cylinder body through the transparent plate 111 on the fixed frame 110 to avoid accidents and prevent the debris generated by the processing of the cylinder body from splashing onto the staff. The connecting strip 112 is installed on the transparent plate 111 to improve the strength of the transparent plate 111 and extend its service life, thereby solving the problem of the existing cylinder body four-axis processing bottom claw positioning and clamping device. When the centering sleeve 104 is used in conjunction with the positioning support plate to fix the workpiece and process it, the debris generated splashes everywhere, which is easy to cause harm to the operator observing the processing nearby, resulting in inconvenience in use.

The collection box 203 is slidably connected to the guide rail 202 and is located on one side of the guide rail 202. The debris generated during the cylinder body processing can be collected through the collection box 203, and after the processing is completed, the collection box 203 is slid out from the guide rail 202 to process the debris therein.

[0032] Secondly, the rotating rod 204 is rotatably connected to the four-axis machine tool 106 and is located on one side of the four-axis machine tool 106. The baffle 205 is fixedly connected to the rotating rod 204 and slidably connected to the collection box 203 and is located on one side of the rotating rod 204. When the collection box 203 needs to be slid out of the guide rail 202, the rotating rod 204 is first rotated to drive the baffle 205 to move, so that the baffle 205 no longer resists the collection box 203, making it convenient for the staff to slide the collection box 203 out of the guide rail 202.

[0033] The bottom jaw positioning and clamping device for four-axis machining of a cylinder body described in this embodiment, when it is necessary to slide the collection box 203 off the guide rail 202, first rotate the rotating rod 204 to drive the baffle 205 to move, so that the baffle 205 no longer presses against the collection box 203, making it convenient for the staff to slide the collection box 203 off the guide rail 202 and then deal with the debris therein.
