Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing machine tools, and more particularly to a mechanical processing machine tool with adjustable height. Background Art

[0002] The existing mechanical processing machine tools lack an effective height adjustment method when processing workpieces, which makes it inconvenient for workers to adjust the position of the workpiece during processing, and it is difficult to accurately observe the processing results of the workpiece, resulting in reduced utilization efficiency of the device. The existing mechanical processing machine tools will produce certain vibrations when working. Long-term exposure to a vibration environment will aggravate the wear of the machine tool itself, resulting in a reduced service life of the machine tool. The existing patent is a mechanical processing machine tool with adjustable height. The patent authorization number is CN 216264568 U. The threaded sleeve drives the equipment frame to rise and fall through the cooperation of the motor and the threaded rod to adjust the height of the equipment frame. At the same time, the cooperation with the slide rod and the limit guide rod can ensure the stability of the equipment frame when rising and falling, avoiding the problem that the worker cannot adjust the position of the workpiece during processing and it is difficult to accurately observe the processing results of the workpiece due to the lack of an effective height adjustment method of the machine tool, thereby improving the utilization efficiency of the device.

[0003] However, in the patent authorization number CN 216264568 U, the output shaft of the motor drives the threaded rod to rotate, so that the threaded sleeve drives the equipment frame to rise and fall, so as to adjust the height of the equipment frame to adapt to the overall processing requirements. Since only the height of the equipment frame can be adjusted, the height of the machine tool workbench cannot be adjusted. When the workpiece to be processed is placed on the machine tool workbench, the operator's height is different and the optimal working posture cannot be adjusted. Therefore, we propose a height-adjustable machining machine to solve the above-mentioned problems. Utility Model Content

[0033] Example:

[0034] See also Figure 1-6 , a height-adjustable machining machine tool, comprising a machine tool workbench 1;

[0035] The lower surface of the machine tool workbench 1 is symmetrically fixedly connected with a support plate 2, and the inner vertical surface of the support plate 2 is welded with a connecting plate 3;

[0036] A support frame 7 is installed below the support plate 2. A transmission shaft 8 is rotatably connected to the inner bottom of the support frame 7. A driving bevel gear 9 is installed on the transmission shaft 8. A right-angle reducer 12 is symmetrically installed on the outer side of the support frame 7. The output end of the right-angle reducer 12 is transmission-connected to the transmission shaft 8. The power input end of the right-angle reducer 12 is transmission-connected to a drive motor 13 through a coupling.

[0037] A shaft 4 is installed through the connecting plate 3, and the two ends of the shaft 4 are rotatably connected to the bottom surface of the machine tool table 1 and the inner bottom wall of the support frame 7 respectively. A threaded portion 5 is provided on the outer wall of the shaft 4, and the threaded portion 5 is screwed to the connecting plate 3. A driven bevel gear 6 is installed on the outer wall of the shaft 4 below the threaded portion 5, and the driven bevel gear 6 is meshed with the driving bevel gear 9;

[0038] The outer surface of the support plate 2 is symmetrically fixed with guide blocks 11 , and the outer walls on both sides of the support frame 7 are symmetrically provided with guide holes 10 , and the guide blocks 11 are slidably connected to the guide hole 10 brackets.

[0039] It should be noted that by connecting the drive motor 13 to an external control device and using the control device to set a suitable forward and reverse rotation program for the power output end of the drive motor 13, the right-angle reducer 12 is driven by the power output end of the drive motor 13, and the right-angle reducer 12 drives the transmission shaft 8 to cooperate with the support frame 7 to operate, and then the active bevel gear 9 engages the driven bevel gear 6 to rotate the shaft 4, and the connecting plate 3 rotates with the threaded portion 5, so that the guide block 11 can move up and down with the guide hole 10, and then the height of the machine tool worktable 1 can be adjusted, so that workers of different heights can adjust the height of the machine tool worktable 1 to adapt to the best working posture.

[0040] like Figure 1As shown, an equipment mounting frame 14 is installed at the edge of the upper surface of the machine tool workbench 1, and the equipment mounting frame 14 is arranged in an L-shaped structure. A fan group 15 is installed at the root of the equipment mounting frame 14, and the air outlet end of the fan group 15 corresponds to the upper surface of the machine tool workbench 1;

[0041] It should be noted that after the workpiece placed on the machine tool workbench 1 is processed, the fan group 15 installed at the equipment mounting frame 14 is powered on to clean the metal debris left on the machine tool workbench 1, which is very convenient to clean.

[0046] It should be noted that the shaft 4 can keep rotating, so that the threaded portion 5 provided on the shaft 4 can be used in conjunction with the connecting plate 3 to realize the lifting and lowering of the machine tool worktable 1.

[0047] like Figure 1 As shown, the guide block 11 extends to the inner side of the guide hole 10, and the outer wall of the guide block 11 fits the inner wall of the guide hole 10. The inner wall of the guide hole 10 and the outer wall of the guide block 11 are both coated with a wear-resistant coating, and the wear-resistant coating is made of silicon carbide;

[0048] It should be noted that the stability of the guide block 11 in cooperation with the guide hole 10 during movement is ensured, thereby ensuring the stability of the machine tool worktable 1 during adjustment, while reducing the wear between the guide block 11 and the guide hole 10.

[0049] During use: by connecting the drive motor 13 to an external control device, and using the control device to set a suitable forward and reverse rotation program for the power output end of the drive motor 13, the right-angle reducer 12 is driven by the power output end of the drive motor 13, and the right-angle reducer 12 drives the transmission shaft 8 to cooperate with the support frame 7 to operate, and then the active bevel gear 9 engages the driven bevel gear 6 to rotate the shaft 4, and the connecting plate 3 cooperates with the threaded part 5 to rotate, so that the guide block 11 can cooperate with the guide hole 10 to move up and down, and then the height of the machine tool worktable 1 can be adjusted.
