Technical Field

[0001] This utility model relates to the field of gantry support technology, and specifically to a gantry support for a machining center. Background Technology

[0002] Gantry cranes are essential for factories and companies in their daily production needs, including moving equipment, loading and unloading goods in and out of warehouses, lifting and repairing heavy equipment, and transporting materials. With the development of the manufacturing industry, CNC machining centers are increasingly widely used in industrial production, especially in aerospace, automobile manufacturing, and mold processing. Gantry machining centers have become the preferred equipment for processing large workpieces due to their stable structure, high rigidity, and large processing range. In the process of lifting and installing large equipment, due to the large size and height of the equipment, it is inconvenient to fix the lifting cables to the surface of the equipment. In this case, it is necessary to use ladders or other tools to lift the workers to a certain height before fixing the lifting cables to the surface of the equipment.

[0003] However, in actual use, escalators or other tools need to be carried back and forth by operators, and it is inconvenient to adjust them freely according to the height of the equipment during use, resulting in low ease of use. This leads to a slow fixing speed of the lifting steel cable and low handling efficiency.

[0004] Therefore, it is necessary to invent a gantry support for machining centers to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a gantry support for a machining center to solve the problem that ladders or other tools are not easy to adjust freely according to the height of the equipment, resulting in low ease of use, which in turn leads to slow fixing speed of lifting steel cables and low handling efficiency.

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 6 The diagram shows a gantry frame for a machining center, comprising a gantry frame body 1. A lifting device body 11 is provided on the lower side of the crossbeam in the gantry frame body 1. Two sets of transmission components 2 are provided on the upper side of the crossbeam in the gantry frame body 1. A protective plate 4 is fixedly connected to the upper side of the transmission components 2. A lifting component 3 that can slide left and right is provided on the surface of the transmission components 2. The lifting component 3 includes a mounting plate 31, a transmission frame 311, an adjusting screw 312, a guide groove 313, a second motor 314, a transmission rod 315, a first support block 316, a scissor lift 36, a working platform 37, a guide rod 371, a positioning slider 372, and a second support block 373.

[0026] When using the gantry frame body 1 to transport equipment, the lifting device body 11 is first moved to the upper side of the equipment. Then, the steel cable in the lifting device body 11 is lowered, and the hook or clamp at the lower end of the steel cable is fixed to the equipment. The lifting device body 11 then raises the steel cable to lift the equipment. The gantry frame body 1 is then moved to transport the equipment. When the equipment is at a high height, the lifting assembly 3 can be used to raise the work platform 37 to a suitable working height for fixed operation. At the same time, the transmission assembly 2 can adjust the left and right positions of the work platform 37, making it easier to move the workers to different positions, effectively improving the convenience and efficiency of the operation.

[0027] See Figures 4 to 6The transmission frame 311 is fixedly connected to the left side of the lower surface of the mounting plate 31. Guide grooves 313 are provided on both the front and rear surfaces of the transmission frame 311. The two ends of the transmission rod 315 are slidably connected to the two sets of guide grooves 313 respectively. The two ends of the adjusting screw 312 are rotatably connected to the left and right surfaces of the transmission frame 311 respectively. The second motor 314 is fixedly installed on the right side of the transmission frame 311. The output end of the second motor 314 is fixedly connected to the right end of the adjusting screw 312. The middle part of the transmission rod 315 is threadedly connected to the adjusting screw 312. The left side of the upper end of the scissor lift 36 is connected to the front and rear surfaces of the transmission rod 315 respectively. The two ends are rotatably connected. Two sets of first support blocks 316 are fixedly connected to the right side of the lower surface of the mounting plate 31. The right side of the upper end of the scissor lift 36 is rotatably connected to the two sets of first support blocks 316 respectively. Two sets of guide rods 371 are fixedly connected to the left side of the upper surface of the working platform 37. Positioning sliders 372 are slidably connected to the surfaces of the two sets of guide rods 371. The left side of the lower end of the scissor lift 36 is rotatably connected to the two sets of positioning sliders 372 respectively. Two sets of second support blocks 373 are fixedly connected to the right side of the upper surface of the working platform 37. The right side of the lower end of the scissor lift 36 is rotatably connected to the two sets of second support blocks 373 respectively.

[0028] Specifically, during use, the lifting assembly 3 activates the second motor 314. The output of the second motor 314 drives the adjusting screw 312 to rotate. The adjusting screw 312 drives the transmission rod 315 to move to the right, thereby unfolding the scissor lift 36 downwards. At this time, the working platform 37 moves downwards. When the operator is on the upper side of the working platform 37, the second motor 314 rotates in the opposite direction, cooperating with the adjusting screw 312 to push the transmission rod 315 to the left, thereby causing the scissor lift 36 to fold upwards and retract, moving the working platform 37 upwards to adjust the height of the operator.

[0029] Meanwhile, when the work platform 37 is not in use, the second motor 314 and the adjusting screw 312 work together to move the transmission rod 315 to the leftmost end. At this time, the scissor lift 36 moves the work platform 37 to the top, avoiding any impact on equipment transportation and enabling automatic storage of the lifting component 3. This eliminates the need for operators to carry it back and forth, further improving the convenience of operation.

[0030] See Figures 2 to 4The transmission assembly 2 includes a fixed plate 21, a linear guide rail 22, a transmission screw 23, and a first motor 24. Two sets of linear guide rails 22 are provided, and fixed plates 21 are fixedly connected to both ends of the two sets of linear guide rails 22. The fixed plates 21 are fixedly connected to the upper surface of the crossbeam in the gantry frame body 1. The two ends of the transmission screw 23 are rotatably connected to the middle of the two sets of fixed plates 21 respectively. The first motor 24 is fixedly installed on the surface of the outer fixed plate 21. The output end of the first motor 24 is fixedly connected to the right end of the transmission screw 23. Two sets of connecting frames 32 are fixedly connected to the upper surface of the mounting plate 31. Positioning grooves 33 are opened on the front and rear sides of the upper end of the two sets of connecting frames 32. The positioning grooves 33 on the front and rear sides are slidably connected to the linear guide rails 22 on the front and rear sides respectively. A connecting rod 34 is fixedly connected between the two sets of connecting frames 32. A transmission block 35 is fixedly connected to the middle of the connecting rod 34. The transmission block 35 is threadedly connected to the transmission screw 23.

[0031] In addition, during the process of adjusting the height of the operator by the lifting assembly 3, the first motor 24 is started. The output end of the first motor 24 drives the transmission screw 23 to rotate. The transmission screw 23 drives the transmission block 35 to move left and right, which in turn drives the connecting frame 32 to slide on the surface of the two sets of linear guide rails 22. The linear guide rails 22 and the connecting frame 32 cooperate to position the lifting assembly 3, improving the stability of the lifting assembly 3 during movement. At the same time, the connecting frame 32 drives the mounting plate 31 to move left and right, adjusting the left and right position of the work platform 37, realizing precise adjustment of the work position, which can greatly improve the convenience and safety of operation.

[0032] The working principle of this utility model is as follows: The lifting component 3 drives the working platform 37 to move up and down to adjust the height of the operator. During the operation, the height of the working platform 37 can be freely adjusted, which facilitates the fixing of equipment at different heights. At the same time, the transmission component 2 can adjust the left and right position of the working platform 37, effectively improving the convenience of operation. Furthermore, through the cooperation of the second motor 314 and the adjusting screw 312, the transmission rod 315 is pushed to the left, which folds and retracts the scissor lift 36, moving the working platform 37 to the top. This allows the working platform 37 to be automatically folded and stored when not in use, further improving the convenience of use and avoiding any impact on equipment transportation.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
