DETAILED DESCRIPTION

[0026] See also Figure 1-4A magnesium alloy die-casting clamping device comprises a base 1, a workbench 2 is arranged above the base 1, a clamping assembly 3 for clamping the magnesium alloy die-casting is arranged on the workbench 2, an adjusting assembly 4 for adjusting the height and rotation angle of the workbench 2 is arranged between the base 1 and the workbench 2, movable wheels 5 are arranged on the four corners of the bottom of the workbench 2, and a braking assembly 6 for braking the movement of the movable wheel 5 is arranged at a position corresponding to each movable wheel 5 on the workbench 2.

[0027] The brake assembly 6 includes a threaded hole 61 extending through the upper surface of the base 1 , and a threaded rod 62 is threadedly sleeved in the threaded hole 61 .

[0028] A knob 63 is fixedly installed on the top of the threaded rod 62, and a brake plate 64 is rotatably connected to the bottom of the threaded rod 62. Telescopic rods 65 are symmetrically arranged on both sides of the threaded rod 62, and the two ends of the telescopic rods 65 are fixedly connected to the top inner wall of the base 1 and the top of the brake plate 64 respectively.

[0029] When in use, the knob 63 is turned, and the rotation of the knob 63 causes the threaded rod 62 to move up and down in the threaded hole 61. Under the guidance of the telescopic rods 65 on both sides, the threaded rod 62 moves up and down, driving the brake plate 64 to move up and down, thereby making the brake plate 64 approach or move away from the movable wheel 5, completing the braking and releasing of the movable wheel 5.

[0030] Such a design not only allows the movement of the threaded rod 62 to be precisely controlled by turning the knob 63, thereby achieving precise adjustment of the position of the brake plate 64; the user also only needs to turn the knob 63 to brake and release the movable wheel 5, which is simple and convenient to operate; at the same time, the guiding effect of the telescopic rods 65 on both sides ensures the stability of the movement of the threaded rod 62 and the brake plate 64, thereby improving the reliability of the braking system; in addition, it can adapt to different working conditions and requirements, and flexibly adjust the distance between the brake plate 64 and the movable wheel 5.

[0031] The brake plate 64 is in an arc-shaped structure and matches the movable wheel 5 . A brake pad 66 is arranged on the inner wall of the brake plate 64 . The brake pad 66 is made of an elastic wear-resistant material.

[0032] With such a design, firstly, the brake plate 64 has an arc-shaped structure and matches the movable wheel 5, so that the brake plate 64 can better fit the movable wheel 5, increase the contact area, and enhance the braking effect; secondly, by arranging a brake pad 66 on the inner wall of the brake plate 64, the friction between the brake plate 64 and the movable wheel 5 is increased, thereby improving the braking effect; thirdly, by using elastic wear-resistant material for the brake pad 66, not only the braking process is made smoother and the impact is reduced, but also the wear-resistant property prolongs the service life of the brake pad 66.

[0033] The clamping assembly 3 includes a groove 31 formed on the top of the workbench 2 . A double-threaded rod 32 is disposed in the groove 31 , and two ends of the double-threaded rod 32 rotate in opposite directions.

[0034] One end of the double-threaded rod 32 is rotatably connected to the inner wall of the groove 31 , and the other end of the double-threaded rod 32 passes through the workbench 2 and is transmission-connected to the first motor 33 , which is fixedly mounted on the workbench 2 .

[0035] The double-threaded rod 32 is symmetrically threaded with two driving blocks 34 , and the driving blocks 34 are slidably connected to the groove 31 . The top of each driving block 34 extends above the groove 31 and is fixedly connected with a clamping plate 35 .

[0036] When in use, the first motor 33 is started to drive the double-headed threaded rod 32 to rotate. Since the two ends of the double-headed threaded rod 32 rotate in opposite directions and the driving block 34 is slidably connected to the groove 31, the two driving blocks 34 move toward or away from each other along the groove 31 under the action of the threads. As the two driving blocks 34 move, the clamping plate 35 connected on the top also moves accordingly, thereby clamping and releasing the magnesium alloy die-casting workpiece.

[0037] Such a design can not only clamp magnesium alloy die-casting workpieces of different shapes and sizes, thus improving the versatility of the device, but also has a simple structure, low manufacturing cost and easy maintenance.

[0038] An anti-skid pad 36 is disposed on one side wall of the two clamping plates 35 that are close to each other. In this embodiment, the anti-skid pad 36 is made of rubber.

[0039] The adjusting assembly 4 includes a lifting assembly 41 for adjusting the height of the workbench 2 and a rotating assembly 42 for adjusting the rotation angle of the workbench 2 .

[0040] The rotating assembly 42 includes a rotating rod 421 , a rotating disk 422 is fixedly connected to the top of the rotating rod 421 , and the top of the rotating disk 422 is fixedly connected to the lifting assembly 41 .

[0041] The top of the rotating rod 421 passes through the base 1 and extends to the inside of the base 1 and is rotatably connected to the bottom inner wall of the base 1 , and a bearing 423 is fixedly provided at the connection between the rotating rod 421 and the base 1 .

[0042] A worm gear 424 is fixedly sleeved on the rotating rod 421 located in the base 1 , and two fixing plates 425 are symmetrically arranged on both sides of the worm gear 424 . The two ends of the fixing plates 425 are fixedly connected to the top inner wall of the base 1 and the bottom inner wall of the base 1 respectively.

[0043] A worm 426 is rotatably connected between the two fixing plates 425 , and the worm 426 is meshingly connected with the worm wheel 424 . A second motor 427 is fixedly connected to one of the fixing plates 425 , and the second motor 427 is drivingly connected to the worm 426 .

[0044] The lifting component 41 is an electric telescopic rod, a telescopic cylinder, or a telescopic oil cylinder.

[0045] In this embodiment, the lifting component 41 is an electric telescopic rod 65 .

[0046] When in use, first start the lifting assembly 41, adjust the height of the workbench 2 to a suitable position, close the lifting assembly 41, and then start the second motor 427. The second motor 427 drives the worm 426 to rotate. Since the worm 426 is meshingly connected with the worm wheel 424, the rotation of the worm 426 drives the worm wheel 424 to rotate synchronously. The rotation of the worm wheel 424 drives the turntable 422 to rotate through the rotating rod 421, and the turntable 422 drives the workbench 2 to rotate through the lifting assembly 41, thereby realizing the adjustment of the rotation angle of the workbench 2.

[0047] Such a design, firstly, can accurately control the height and rotation angle of the workbench 2, so as to adapt to different work requirements and flexibly adjust the state of the workbench 2; secondly, the operation is convenient and fast, thereby improving work efficiency.

[0048] When in use, the clamping device is moved to the work site, and then the four threaded rods 62 are rotated respectively, so that the four brake plates 64 move downward under the guidance of the telescopic rod 65 and abut against the four movable wheels 5 for braking, thereby fixing the entire device at the work site to prevent uncontrolled movement due to external forces during the work process.

[0049] The magnesium alloy casting is then placed on top of the workbench 2 and between the two clamps 35. The first motor 33 is then started to drive the double-headed threaded rod 32 to rotate forward. Since the two ends of the double-headed threaded rod 32 rotate in opposite directions and the drive block 34 is slidably connected to the groove 31, the two drive blocks 34 move toward each other along the groove 31 under the action of the threads. As the two drive blocks 34 move, the clamp 35 connected on the top also moves accordingly, thereby clamping the magnesium alloy die-casting workpiece.

[0050] When the height and angle of the workbench 2 need to be adjusted, first start the lifting assembly 41, adjust the height of the workbench 2 to a suitable position, close the lifting assembly 41, and then start the second motor 427. The second motor 427 drives the worm 426 to rotate. Since the worm 426 is meshingly connected with the worm wheel 424, the rotation of the worm 426 drives the worm wheel 424 to rotate synchronously. The rotation of the worm wheel 424 drives the turntable 422 to rotate through the rotating rod 421, and the turntable 422 drives the workbench 2 to rotate through the lifting assembly 41, thereby realizing the adjustment of the rotation angle of the workbench 2. When the workbench 2 rotates to a suitable angle, stop the second motor 427.

[0051] For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the protection scope of the present invention.
