It can process planes (horizontal and vertical surfaces), grooves (keyways, T-slots, dovetail grooves, etc.), toothed parts (gears, spline shafts, sprockets), spiral surfaces (threads, spiral grooves) and various curved surfaces. In addition, it can also be used for processing the surface of rotating bodies, internal holes and cutting. When the milling machine is working, the workpiece is mounted on the workbench or on accessories such as the indexing head. The rotation of the milling cutter is the main motion, supplemented by the feed motion of the workbench or the milling head, and the workpiece can obtain the required processing surface. Due to the multi-blade intermittent cutting, the productivity of the milling machine is relatively high. Simply put, the milling machine is a machine tool that can perform milling, drilling and boring on the workpiece.

When the work station plate returns to the specified position after processing, the entire positioning pin is taken out by the second cylinder, so that the workpiece can continue to be placed on the workpiece plate for processing.

[0009] Further configuration: a stabilizing device is also provided on the feed port, and the stabilizing device includes a concave chute connected to the feed port on both sides and a slider located on both sides of the work station plate for clamping into the concave chute.

[0010] By adopting the above technical solution, the provided stabilizing device can effectively enable the work station plate to smoothly enter the feed port, so that it can be effectively processed by the milling machine.

[0011] Further configuration: auxiliary devices are also provided on both sides of the feed port, and the auxiliary devices include auxiliary cylinders provided on both sides of the slide slot and a second electromagnetic relay provided at the outlet of the auxiliary cylinder and cooperating with the slider.

[0012] By adopting the above technical solution, the auxiliary device can effectively help the work station plate to move in front of the feed port, thereby effectively assisting the pushing cylinder to push the work station plate to the position of the feed port, effectively increasing the stability of the workpiece.

[0013] It is further configured that: a protective shell for covering the moving path of the second electromagnetic relay is also provided on the outer wall of the slide slot.

[0016] By adopting the above technical solution, the provided fixing device can effectively determine the position of the work station plate at the beginning, thereby providing an initial accurate basis for subsequent work, and the provided soft insert can be effectively inserted into the slot at the bottom of the work station plate. At the same time, since it is a soft insert, it will not affect the pushing of the pushing cylinder, so subsequent work can be effectively carried out.

[0017] In summary, the present invention has the following beneficial effects: it can effectively stabilize the entire work station plate, and at the same time, after stabilizing the work station plate, its initial accuracy is higher, reducing the change in placement position during transportation, thereby causing accuracy errors, and effectively improving production accuracy.

A work station plate 34 is provided at the outlet of the first cylinder 32, a fixing device 7 is also provided between the work station plate 34 and the outlet of the first cylinder 32, the fixing device 7 comprises a base 71 provided at the outlet of the first cylinder 32, support blocks 72 for supporting the work station plate 34 are provided on both sides of the upper surface of the base 71, and a soft insert 73 vertically upward is provided between the support blocks 72, and a slot 74 matching the soft insert 73 is also provided at the bottom of the work station plate 34.

[0024] The work station plate 34 is provided with a plurality of positioning holes 35, the outlet of the second cylinder 33 is provided with a plurality of positioning pins 36 matching the positioning holes 35, and an iron block 37 is provided at the top of the positioning pin 36. A first electromagnetic relay 38 is also fixedly provided at the outlet of the second cylinder 33, and a groove 39 is provided at the bottom of the first electromagnetic relay 38. The iron block 37 at the top of the positioning pin 36 is inserted into the groove 39, so that the positioning pin 36 can be fixed at the outlet of the second cylinder 33 by starting the first electromagnetic relay 38. At the same time, the work station plate 34 is provided with a plurality of positioning holes 35 matching the positioning pin 36, so as to effectively fix the work station plate 34, and the bracket 31 is also provided with a pushing cylinder 310 for pushing toward the feed port 2.

[0025] A stabilizing device 4 is also provided between the pushing cylinder 310 and the feed port 2, and the stabilizing device 4 includes a concave chute 41 connected to the feed port 2 on both sides and a slider 42 located on both sides of the work plate 34 for inserting into the concave chute 41. An auxiliary device 5 is also provided on both sides of the feed port 2, and the auxiliary device 5 includes an auxiliary cylinder 51 located on both sides of the chute and a second electromagnetic relay 52 located at the outlet of the auxiliary cylinder 51 and cooperating with the slider 42.
