Referring now to fig. 1 to 3, the workpiece is a front frame 101 of a refrigerated container 200 for mounting a refrigeration unit 210 by bolts. In the illustrated embodiment, the front frame 101 is rectangular, and holes are punched on four sides thereof.

Referring now to fig. 4 to 6, the laser cutting and punching apparatus 100 is provided with a lifting device 120. Each of the lifting devices includes a positioning plate 121 and a lifting rod 125, and the positioning plate 121 can be moved up and down between a retracted position and a lifted position by the lifting rod 125 as will be described in detail below. The positioning plate 121 is provided with an eccentric positioning wheel 122, and when the front frame 101 is supported by the positioning plate 121, the eccentric positioning wheel 122 makes the front frame 101 perform position adjustment in the horizontal direction through a rotating action. In addition, a moving rail 112 is installed above the lifting device 120, and a plane on which the moving rail 112 is located and a plane on which the front frame 101 is located are parallel. A laser cutting head 113 capable of moving along the track is mounted on the moving track 112, and the laser cutting head 113 is connected to a power system (not shown) and a control device (not shown), so that the control device can control the movement of the laser cutting head 113 relative to the moving track 112 and perform punching on the front frame 101.

In this way, the front frame 101 is well protected from the offset of the hole sites due to misalignment when drilling, thereby affecting the later installation process. Moreover, compared with the drilling of the electric drill before improvement, the laser cutting has the advantage that the influence of noise is greatly reduced.

In fig. 5 and 6, the moving rail 112 is mounted on the base 110, specifically, connected to the top end of the base 110. In addition, the elevating device 120 is connected to the bottom end of the base 110. The feeding wheel 114 is connected with the base 110 through a special transmission device, the axis of the feeding wheel 114 is parallel to the plane of the positioning plate 121, and the feeding wheel 114 is arranged between the lifting position and the retracting position of the positioning plate 121.

In fig. 4, the cross-sectional shape of the base 110 may be substantially rectangular, and a total of 4 sets of the lifting devices 120 are installed at positions on two corresponding sides of the base 110. Wherein each of the lifting devices includes four lifting rods 125 and four lifting gears 127. Wherein each lifting rod 125 is perpendicular to the positioning plate 121. The positioning plate 121 is fixedly connected with four lifting rods 125 through bolts. And the lifting rod 125 has a rack gear structure 126 at a side thereof, and the rack gear structure 126 of the lifting rod 125 is engaged with the lifting gear 127. The lifting gear 127 is connected with the driving motor 111 through a transmission system inside the lifting device 120. The lifting gear 127 is rotated by the driving motor 111, thereby moving the lifting rod 125 up and down with respect to the base 110.

In this way, the four lifting rods 125 can move up and down synchronously, ensuring that the positioning plate 121 is always parallel to the bottom of the base 110. The front frame 101 is moved into the laser cutting and punching device 100 by the feeding wheel 114, the positioning plate 121 moves from the retracted position to the lifted position, and during the movement, the positioning plate 121 supports the front frame 101 to move upward and away from the feeding wheel 114 until the lifted position is reached.

Six eccentric positioning wheels 122 are fixedly mounted on the positioning plate 121, and each eccentric positioning wheel 122 comprises a fixed shaft 123 and a rotating wheel 124. Wherein, the fixed shaft 123 is fixed on the positioning plate 121. The rotating wheel 124 is eccentrically sleeved outside the fixed shaft 123 and is rotatable relative to the fixed shaft. The eccentric positioning wheel 122 is connected with a driving motor. So that the rotation wheel 124 can be eccentrically rotated about the fixed shaft 123. The outer circumferential surfaces of the six rotation wheels 124 are in contact with the front frame 101 and rotated at a certain angle to position the front frame 101.

Preferably, the positioning plate 121 and the moving rail 112 have a rectangular outer profile in cross section, and the upper and lower surfaces are parallel.

In this way, in the punching process of the front frame 101, not only the accuracy of the hole position is ensured, but also the loss of the front frame 101 caused by the inclination of the front frame 101 is avoided.
