Detailed Description
The utility model provides a fixing device for a working platform of a laser cutting machine, which is further described in detail below by referring to the attached drawings and embodiments in order to make the purpose, technical scheme and effect of the utility model clearer and clearer. It should be understood that the specific embodiments described herein are merely illustrative of the utility model and do not limit the scope of the utility model.
Referring to fig. 1 to 3, the present invention provides a fixing device for a work platform of a laser cutting machine, including a pressing member swingably provided on a main bed 31, the pressing member being capable of pressing the end of the work platform, and a linear actuator 2 for driving the pressing member closer to or farther from the end of the work platform.
For a common laser cutting machine with double working platforms in the market, a plate to be processed is firstly placed on the working platform on the auxiliary bed body 32, and then the positions of the two working platforms 8 are exchanged through the chain transmission device 7, so that the working platform is translated to a set processing area to realize cutting operation. The chain transmission device 7 mainly comprises a driving chain wheel arranged at one end of the main bed body 31, a driving motor used for driving the driving chain wheel to rotate and a driven chain wheel arranged at the other end of the main bed body 31, the driving chain wheel and the driven chain wheel are in transmission connection through a chain 71, and the working platform is connected with the corresponding chain through a chain buckle plate. When the working platforms are exchanged, the driving motor drives the driving chain wheel to rotate, the driven chain also synchronously rotates under the transmission of the chain, and the chain moves along a waist-shaped motion track and pulls the working platforms to smoothly and horizontally move through the chain buckle plates. Although the driving motor is stopped after the working platform is in place, the chain is still in a relaxed state, and the chain and the working platform are easy to shake together in the cutting process. At this moment, the linear driver 2 drives the pressing piece to swing towards the end of the working platform, then the pressing piece is in a vertical state and is pressed on the end of the working platform and applies pressure on the working platform, so that the chain 71 is tensioned by the working platform 8, the working platform cannot shake in the cutting process, and the machining precision of the workpiece is ensured.
It should be noted that, when the work platform is exchanged, in order to prevent the pressing bar 1 from interfering with the movement of the work platform, the linear actuator 2 drives the pressing member to return to the horizontally extending state.
Specifically, the pressing part is a pressing strip 1, one end of the pressing strip 1 is fixedly provided with a rotating shaft 41, the main bed body 31 is provided with a bearing 42 with a seat, the rotating shaft 41 is rotatably connected with the bearing 42 with the seat, and the linear driver 2 is hinged with the middle part of the pressing strip 1. In practical application, the fixing device is lower than the working platform and is disposed on the bottom frame 311 of the main bed 31, the bottom frame 311 includes two first beams 3111 symmetrically disposed and a plurality of second beams 3112 disposed between the two first beams 3111, and the bearing 42 with seat is mounted on the upper surface of one of the second beams 3112. With this arrangement, the molding 1 is in a horizontal state in an initial state, and the molding 1 can smoothly swing to a vertical state around the axis of the rotating shaft 41 under the driving of the linear driver 2.
