As shown in fig. 4, 5 and 7, in the present embodiment, the translating assembly 300 includes an avoiding cylinder 301, a first sliding base 302 and a second sliding base 303.

The first sliding bases 302 are connected with an output end of the electric lifting assembly 400, and specifically, the connecting assemblies on the screw rods 405 of the electric lifting assembly 400 are respectively connected and fixed with the two first sliding bases 302. The first slider 302 is connected to the guide bar 501 of the base 500 in a vertically sliding manner.

The second sliding base 303 can be connected with the first sliding base 302 in a sliding way through a guide rail sliding block pair or an optical axis, so that the second sliding base 303 can slide in the left-right direction relative to the first sliding base 302.

The milling cutter assembly 200 may be mounted on the second slide 303 by bolts.

When a piston rod of the avoiding cylinder 301 extends, the avoiding cylinder 301 can drive the second sliding seat 303 and the milling cutter assembly 200 to move to the right, so that the milling cutter assembly 200 can pre-mill the step surface of the plate 100. When the piston rod of the avoiding cylinder 301 is shortened, the avoiding cylinder 301 can drive the second sliding base 303 to drive the milling cutter assembly 200 to move towards the left, so that the milling cutter assembly 200 is far away from the step surface of the plate 100, and the pre-milling of the plate 100 by the milling cutter assembly 200 is avoided.

As shown in fig. 4, 6 to 8, in some embodiments, the first sliding seat 302 is provided with a shaft hole, the second sliding seat 303 includes a connecting plate 304 and a connecting seat 305, the connecting plate 304 and the connecting seat 305 are fixedly connected by two optical axes 306, and the two optical axes 306 are correspondingly disposed through the shaft hole of the first sliding seat 302, so that the second sliding seat 303 can move smoothly in the left-right direction relative to the first sliding seat 302. The piston rod of the avoiding cylinder 301 is fixedly connected with the connecting plate 304, and the piston rod of the avoiding cylinder 301 can drive the connecting plate 304 to move together with the connecting seat 305. And the milling cutter assembly 200 is mounted on the connecting block 305.

The first slider 302 is provided with a counter 308, a screw 309 is provided in a connection hole of the counter 308, and the screw 309 is mounted on the first slider 302 via a bearing. Both ends of the screw 309 extend in the left-right direction. The right end of the screw 309 is connected with a limiting block 307 through a threaded structure, the cross section of the limiting block 307 is polygonal, specifically square, the right end of the limiting block 307 is a limiting portion, the connecting plate 304 is provided with a limiting hole, and the left end of the limiting block 307 penetrates through the limiting hole and is connected with the inner circumferential surface of the limiting hole in a sliding manner. The limiting block 307 is provided with a threaded through hole and can be connected with the external thread of the screw 309.

When the screw 309 rotates clockwise, the screw 309 rotates around the central axis thereof relative to the first slide base 302, and at this time, the screw 309 is screwed into the threaded through hole of the limit block 307, so that the left-right distance between the limit block 307 and the avoidance cylinder 301 is reduced. When the screw 309 rotates counterclockwise, the screw 309 is screwed out of the threaded through hole of the stopper 307, so that the left-right distance between the stopper 307 and the avoiding cylinder 301 is increased.

After the avoiding cylinder 301 drives the connecting plate 304 to move to the right for a certain distance, the connecting plate 304 is stopped by the limiting part of the limiting block 307, so that the milling cutter assembly 200 is driven to move to the right. When the screw 309 rotates for a certain number of turns, the counter 308 can read the left and right distance between the limiting block 307 and the avoiding cylinder 301, so that the distance of the milling cutter assembly 200 moving to the right under the driving of the avoiding cylinder 301 can be obtained.

The two milling cutter assemblies 200 are spaced apart in the front-to-rear direction. The milling cutter assembly 200 located at the rear side is referred to as a first milling cutter assembly 210, and the milling cutter assembly 200 located at the front side is referred to as a second milling cutter assembly 220, as shown in fig. 3 and 6. It will be appreciated that the first and second milling cutter assemblies 210, 220 are identical in construction.

As shown in fig. 1, 3, 6 and 7, assuming that the plate material 100 moves from front to back, the first and second milling cutter assemblies 210 and 220 perform a preliminary milling process on the step surface of the left side of the plate material 100. The first mill assembly 210 is responsible for pre-milling the rear portion of the left side of the sheet material 100 and the second mill assembly 220 is responsible for pre-milling the front portion of the left side of the sheet material 100.

Specifically, the milling cutter assembly 200 includes a pre-mill and mill motor 203. The output shaft of the milling cutter motor 203 extends in the vertical direction, the output shaft of the milling cutter motor 203 is in transmission connection with the pre-milling cutter, and when the milling cutter motor 203 works, the pre-milling cutter can rotate around the axis extending vertically. The pre-milling cutter is detachably connected with an output shaft of the milling cutter motor 203. In this embodiment, the output shaft of milling cutter motor 203 is located to the milling cutter cover in advance to install in the output shaft of milling cutter motor 203 through the key-type connection mode, then, pass the bolt and connect in the output shaft of milling cutter motor 203, prevent that the milling cutter in advance from throwing away from the output shaft of milling cutter motor 203.

It should be noted that the peripheral surface of the pre-milling cutter is provided with a first blade 201 and a second blade 202, the second blade 202 is located below the first blade 201, and the outer diameter of the first blade 201 is smaller than the outer diameter of the second blade 202, so that the first blade 201 pre-mills the convex surface of the step surface of the plate 100, and the second blade 202 pre-mills the concave surface of the step surface of the plate 100, as shown in fig. 7, and by such design, the accumulation of the scraps generated by the pre-milling operation on the step surface can be avoided. It is understood that fig. 1, 3, 4, 6 to 8 all clearly show the blade of the second blade section 202, but the blade of the first blade section 201 is not shown.

Further, as shown in fig. 6, in the two milling cutter assemblies 200, the cutting edges of the pre-mill are rotationally arranged inward toward each other in the direction of rotation. When the plate material 100 moves from front to back, the pre-mill of the first mill assembly 210 rotates clockwise in the pre-milling operation, and the pre-mill of the second mill assembly 220 rotates counterclockwise in the pre-milling operation.

It can be understood that, as shown in fig. 6, when the plate 100 moves from front to back, the second milling cutter assembly 220 is driven by the translation assembly 300 to move to the left, so that the pre-milling cutter of the second milling cutter assembly 220 is spaced from the plate 100, and the second milling cutter assembly 220 is temporarily not pre-milled. In the process of moving the plate 100 backward, the pre-milling cutter of the first milling cutter assembly 210 pre-mills the rear part of the step surface of the plate 100, and because the pre-milling cutter of the first milling cutter assembly 210 rotates clockwise, edge breakage or band breakage at the joint between the rear side surface and the left side surface of the plate 100 can be avoided; then, the pre-milling cutter of the second milling cutter assembly 220 pre-mills the front portion of the step surface of the plate 100, and due to the counter-clockwise rotation of the pre-milling cutter of the second milling cutter assembly 220, edge breakage or belt breakage at the connection between the front side surface and the left side surface of the plate 100 can be avoided.
