Hereinafter, several preferred embodiments of the present invention are cited, and further detailed descriptions are made in conjunction with the drawings as follows: As shown in the first to third figures, a preferred embodiment of the present invention is a circular part of a circular knitting machine The processing method and the processing mechanism 10 are mainly to install one of the ring parts 1 of a circular knitting machine on a processing machine 2, and first use the processing machine 2 to perform processing on the inner, outer or end surfaces of the ring parts 1 that are generally cylindrical. Milling or/and drilling, and then using the processing machine 2 to perform milling or/and drilling with an inclination angle on the ring part 1, and depending on the type of processing to control the rotation state of the ring part 1, it is possible to obtain The effect of processing can be performed by replacing the processing machine.

In detail, the ring part 1 is processed after being cut for use as parts of a circular knitting machine, such as parts such as the inner and outer needle cylinder seats of the disc, or inner and outer cam adjustment parts. The processing machine 2 series conventionally includes a worktable 3, a head body 4 and a spindle 5, etc., which can be used for milling and drilling of workpieces. The processing equipment of the processing program, the detailed structure and operation mode of the processing machine 2 will not be repeated here. The worktable 3 is pre-installed with a tilting mechanism 12 and a rotating worktable 14, and an additional head 16 and a number are also provided. The cutter 18, the tilting mechanism 12 is set on the worktable 3 and located below the head body 4, the spindle 5 is set on the bottom end of the head body 4, and the rotary table 14 is a conventional rotary table. Driven by a motor to rotate or rotate by a predetermined angle, it is arranged on the tilting mechanism 12 to install the ring part 1. The tilting mechanism 12 can tilt the rotary table 14 at any angle, and the additional head 16 is a conventional processing method. The additional head of the equipment is detachably set at the bottom end of the main shaft 5. Each of the cutters 18 is a cutter such as a milling cutter and a drilling cutter, and can be installed on the additional head 16 or the additional head 16 is removed and then installed on the main shaft 5. .

When the processing machine 2 performs milling or/and drilling on the inner, outer or end surface of the ring part 1, the tilt mechanism 12 is not activated, and the ring part 1 is in a horizontal state (opening up and down), so that An additional head 16 installed at the bottom end of the main shaft 5 can be used to mill or/and drill the ring part 1, as shown in the first figure. When performing milling processing, the additional head 16 is installed with a milling cutter, the rotary table 14 is intermittently rotated, so that the additional head 16 can mill the ring part 1, and when drilling is performed, the rotary table 14 Then, the intermittent rotation of a predetermined angle is provided for the drilling tool installed with the additional head 16 to perform drilling. The intermittent rotation angle of the rotary table 14 can be controlled by a motor.

When milling or/and drilling with an inclination angle is performed on the ring part 1, the inclination mechanism 12 is driven to enable a rotary operation The table 14 is inclined at a predetermined angle relative to the worktable 3 (depending on the machining angle of the ring part 1), so that the ring part 1 is also in an inclined state. At this time, the additional head 16 is removed, and the cutters 18 are directly removed. It is installed at the bottom end of the main shaft 5, so that the cutter 18 installed at the bottom end of the main shaft 5 can be used to mill or/and drill the inclined ring part 1, as shown in the third figure. When performing milling processing, the tool 18 is a milling cutter, and the rotary table 14 is continuously rotated so that the tool 18 can mill the ring part 1. When drilling is performed, the tool 18 is a drilling tool. The rotary table 14 intermittently rotates a predetermined angle for the tool 18 to drill holes.

In addition, the head body 4 can drive the main shaft 5 and the additional head 16 to move, the workbench 3 is a movable workbench that can drive the tilt mechanism 12, the rotary workbench 14 and the ring part 1 to move, and the additional head 16 can be fixedly locked and removed with the head body 4 to change the machining direction of the tool. The above is a conventional technology.

Secondly, the tilting mechanism 12 includes a base 22, the base 22 is set on the workbench 3, a bearing platform 24 is tilted and movably set on the base 22, and one end is pivotally connected to the base 22 and the other end. It can be driven by a driving mechanism to incline a predetermined angle with respect to the base 22, and the rotary table 14 is arranged on the carrying table 24. The driving mechanism can be a conventional hydraulic, pneumatic or other driving equipment. This embodiment is a hydraulic equipment (not shown) that includes two hydraulic cylinders 26 and a hydraulic supply and control mechanism.

In addition, as shown in Figures 4 and 5, the implementation of the present invention The other processing mechanism 30 of the method for processing circular parts of a disc knitting machine has substantially the same structure as the processing mechanism 10, and the same components use the same symbol symbols. The difference lies in: it does not need to use the tilt mechanism 12, and its structure The additional head 32 is a conventional vertical and horizontal head with three machining directions: horizontal, vertical, and inclined (relative to the spindle 5) (in this embodiment, two machining directions are 90 degrees and 45 degrees), which can be equipped with tools 18 in different machining directions. . Thereby, the processing mechanism 30 still uses the rotary table 14 to drive the ring part 1 to rotate or rotate a predetermined angle, and first uses the horizontal and vertical tool 18 on the additional head 32 to process the inner, outer or end surface of the ring part 1 Then, it is not necessary to remove the additional head 32, and then use the tool in the inclined direction on the additional head 32 to process the annular part 1 with an oblique angle.

It can be seen from the above that the machining mechanism of the circular part of the circular knitting machine of the present invention can process the inner and outer circular parts of the circular part through the cooperation of the rotary table and the additional head, the cutter or/and the tilting mechanism. Tilting processing is integrated on the same processing machine, which solves the disadvantages of dismantling, moving and installing inconveniences and increased man-hours caused by the processing of conventional ring parts on different machines, which is of practical value.

It must be mentioned that although the two-axis spindles of some of the conventional high-end processing equipment may be allowed to rotate and adjust the inclination angle at the same time for the tilt processing of the workpiece, these two-axis spindles are expensive, and some two-axis spindles The head spindle has a relatively large volume and cannot be placed inside the ring part for processing. The space and use range are limited. The present invention does not need to use these expensive spindles. The aforementioned effects can be obtained, and it is even more obvious that the present invention has economic benefits, and does not have the disadvantages of the large-volume two-axis head spindle space and the limited use range.

The above are only two preferred embodiments of the present invention, and are not intended to limit the present invention. Anyone with ordinary knowledge in the relevant technical field can make some modifications without departing from the spirit and scope of the present invention. Modifications and modifications, therefore, the scope of protection of the present invention shall be subject to the scope of the attached patent application.
