[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 , a reaming and honing machine with multiple stations in this embodiment is used to realize multi-station reaming and honing processing;

[0024] Specifically, the present embodiment includes a machine base 1, a seven-sided center column 2 is vertically arranged at the center of the upper surface of the machine base 1, and at least six reaming and honing mechanisms 3 are installed on the outer side of the seven-sided center column 2; a large CNC turntable 4 is rotatably connected to the machine base 1, corresponding to the at least six reaming and honing mechanisms 3, and at least seven processing stations 5 are installed on the large CNC turntable 4, one of which is a loading and unloading station, and the other six processing stations 5 are reaming and honing stations.

[0025] During actual use, the workpiece is placed on the loading and unloading station. The large CNC turntable 4 is rotated to rotate the workpiece on the loading and unloading station to the bottom of the reaming and honing mechanism 3, and the workpiece is processed by the reaming and honing mechanism 3. During the rotation of the large CNC turntable 4, the workpiece on the loading and unloading station passes through the six reaming and honing mechanisms 3 in turn, and the workpiece is processed in turn by the six reaming and honing mechanisms 3.

[0026] Furthermore, in order to facilitate driving the CNC large turntable 4 to rotate, a transmission mechanism 6 connected to the CNC large turntable 4 is installed on the outer side of the machine base 1 to drive the CNC large turntable 4 to rotate.

[0027] During actual use, the CNC large turntable 4 is driven to rotate through the cooperation between the internal components of the transmission mechanism 6, and each rotation of the CNC large turntable 4 at one workstation is one beat, that is, when the CNC large turntable 4 rotates one beat, the workpiece will be moved to the bottom of the next side reaming and honing mechanism 3, and will be processed by the next reaming and honing mechanism 3.

[0028] Specifically, in order to perform reaming and honing processing on the workpiece, the reaming and honing mechanism 3 in this embodiment includes a lifting mechanism 301, a motor 302 and a reaming and honing assembly 303; the lifting mechanism 301 is vertically installed on the outer peripheral surface of the seven-sided center column 2, the motor 302 is assembled on the lifting mechanism 301, the reaming and honing assembly 303 is assembled on the lifting mechanism 301, and the reaming and honing assembly 303 is transmission connected to the motor 302.

[0029] In addition, the reaming and honing assembly 303 includes at least five reaming and honing tools 304 , and the at least five reaming and honing tools 304 are all in driving connection with the motor 302 .

[0030] In actual use, when the operator issues a work instruction at the seventh station, that is, the loading and unloading station, the reaming and honing tool 304 at the 1-6 reaming and honing station is in a state of up and down movement and rotation at the same time through the cooperation of the lifting mechanism 301 and the motor 302.

[0031] Moreover, when the operator loads the workpiece at the seventh station in each beat, after the seventh beat, the five holes on the workpiece loaded in the first beat have been reamed and honed in sequence at six stations to meet the high-precision hole requirements. At this time, the processed workpiece can be removed and replaced with a new one. In this way, the completed workpiece can be removed and replaced with a new one in each continuous beat to continue processing.

[0032] It should be noted that the rotation speed, up and down movement speed, up and down positioning of the reamer and honing tool 304, as well as the rotation speed of the CNC large turntable 4 and the duration of each beat are all regulated by CNC programming and can be set freely. The number and distance of the reamer and honing tools 304 can be configured and adjusted according to different products. After the program is set, the operator only needs to perform simple operations, take down the completed ones according to the beat, and install the new ones, and the operation can be carried out without stopping the machine.

[0033] In detail, one cycle takes about 2 minutes. During this short period of time, dozens of knives work together to perform 6 precision processes on each reaming and honing hole, achieving high efficiency, high precision and multi-purpose use of one machine.

[0034] It should be noted that the CNC large turntable 4 rotates with the seven-sided center column 2 as the base point. In addition, in order to prevent the temperature of the reaming honing tool 304 from being too high, reaming honing fluid is used during processing to reduce the temperature of the reaming honing tool 304. At the same time, a drain pipe 7 is installed at the bottom of the machine base 1 for recovering the reaming honing fluid. The shape of the cross-section of the upper end of the seven-sided center column 2 is a regular heptagon.

[0035] It can be understood that at least five reamer-honing tools 304 are perpendicular to the direction of the processing stations 5 , and at least seven processing stations 5 are distributed in a circular array on the large CNC turntable 4 .

[0036] Furthermore, in order to facilitate the installation of six reaming mechanisms 3 while retaining one workstation for loading and unloading workpieces, the cross-section of the upper end of the seven-sided central column 2 is preferably in the shape of a regular heptagon in this embodiment.

[0037] In actual setting, six reaming mechanisms 3 are respectively installed on six faces of the seven-faceted central column 2 , and the remaining one face is vacant, so as to facilitate loading and unloading of the workpiece on the processing station 5 .

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
