The connecting pin is sleeved and connected to the sleeve. A retaining ring is threaded to the outer wall of the connecting pin.

[0004] In the above-mentioned solutions, locking is achieved by relying on threaded fasteners, and the adjustment process requires multiple tightening of the fixing ring, which is not only inefficient but also prone to loosening in a vibrating environment. Therefore, this application proposes a quick adjustment device for the worktable height of a common milling machine. Summary of the Invention

[0005] In view of the above situation and to overcome the defects of the prior art, this utility model provides a quick adjustment device for the worktable height of a common milling machine, which effectively solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rapid adjustment device for the worktable height of a common milling machine, comprising a worktable, wherein a plurality of T-shaped plates are fixed at the upper end of the worktable, the plurality of T-shaped plates are spaced apart, the T-shaped plates are provided with an adjustment mechanism, and a fixing mechanism is provided at the upper end of the adjustment mechanism.

[0007] Preferably, the adjusting mechanism includes a movable block located between the two T-shaped plates. A mounting cylinder is fixed to one upper side of the movable block, and a support rod is slidably connected inside the mounting cylinder. The fixing mechanism is fixed to the upper end of the support rod. A T-shaped block is fixed to the other upper side of the movable block. A fixing rod is symmetrically slidably connected to one side of the T-shaped block. An adjusting hole is arrayed at the upper end of the T-shaped plate. One end of the fixing rod is movably inserted into the adjusting hole. A circular block is fixed to the outside of the fixing rod. A spring is sleeved on the outside of the fixing rod. One end of the spring is fixedly connected to the T-shaped block, and the other end of the spring abuts against the circular block. The other ends of the two fixing rods extend to the outside of the T-shaped block and are fixed with a pull rod.

[0008] Preferably, a U-shaped block is fixed to the upper part of the mounting cylinder, a fixing rod two is slidably connected to the middle of one side of the U-shaped block, an adjustment hole two is arrayed on one side of the support rod, one end of the fixing rod two is movably inserted into the adjustment hole two, a circular block is fixed to the outside of the fixing rod two, a spring two is sleeved on the outside of the fixing rod two, one end of the spring two is fixedly connected to the U-shaped block, the other end of the spring two abuts against the circular block, and the other end of the fixing rod two extends to the outside of the U-shaped block and is fixed with a pull rod two.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. Through the adjustment mechanism, pulling the first pull rod causes the first fixed rod to disengage from the first adjustment hole, releasing the lock and pushing the moving block along the T-shaped plate to the target position. Releasing the first pull rod causes the first spring to push the first fixed rod back into the corresponding adjustment hole, thus fixing the horizontal position and adapting to the processing position requirements of workpieces of different sizes. Pulling the second pull rod causes the second fixed rod to disengage from the second adjustment hole, releasing the lock and moving the support rod up and down. The operator can control the lifting distance through the scale line on one side of the support rod. After adjusting to the target height, releasing the second pull rod causes the second spring to push the second fixed rod into the corresponding adjustment hole, thus locking the height. Compared with the traditional threaded adjustment method, this height adjustment method is more convenient to operate and faster to adjust. 2. With the fixed mechanism in place, when the worm gear is rotated, the worm gear drives the lower rotating block to rotate while moving up and down along the thread direction, thereby driving the upper lower pressure plate to rise and fall synchronously. When the lower pressure plate moves down, it can press the workpiece to be processed placed on the worktable. The smooth rod slidably connected to the upper end of the rectangular plate is fixed to the lower pressure plate, which can effectively prevent the lower pressure plate from deflecting during the lifting process, ensuring that the contact surface between the lower pressure plate and the workpiece remains parallel, and improving the stability and reliability of workpiece clamping.

One end of the fixing rod 305 is movably inserted into the adjustment hole 306. A circular block is fixed to the outside of the fixing rod 305. A spring 307 is sleeved on the outside of the fixing rod 305. One end of the spring 307 is fixedly connected to the T-shaped block 304. The other end of the spring 307 abuts against the circular block. The other ends of the two fixing rods 305 extend to the outside of the T-shaped block 304 and are fixed with a pull rod 308. The movable block 301 of the adjusting mechanism 3 is set between two T-shaped plates 2. A support rod 303 is slidably connected inside the mounting cylinder 302 on one side of the upper end of the movable block 301. The support rod 303 supports the fixing mechanism 4. A fixing rod 305 is symmetrically slidably connected to the T-shaped block 304 on the other side of the upper end of the movable block 301. The elastic force of the spring 307 pushes the circular block, so that one end of the fixing rod 305 is inserted into the adjusting hole 306 on the T-shaped plate 2, thereby fixing the position of the movable block 301 on the T-shaped plate 2. Pulling the pull rod 308 can drive the fixing rod 305 to disengage from the adjusting hole 306, thereby adjusting the position of the movable block 301. The movable block 301 can move along the T-shaped plate 2. With the locking of the fixing rod 305 and the adjusting hole 306, the horizontal position of the adjusting mechanism 3 can be flexibly adjusted to meet the processing requirements of workpieces of different sizes. A U-shaped block 309 is fixed to the upper part of the mounting cylinder 302. A fixing rod 310 is slidably connected to the middle of one side of the U-shaped block 309. An adjustment hole 311 is arrayed on one side of the support rod 303. One end of the fixing rod 310 is movably inserted into the adjustment hole 311. A circular block is fixed to the outside of the fixing rod 310. A spring 312 is sleeved on the outside of the fixing rod 310. One end of the spring 312 is fixedly connected to the U-shaped block 309. The other end of the spring 312 abuts against the circular block. The other end of the fixing rod 310 extends to the outside of the U-shaped block 309 and is fixed with a pull rod 313. A U-shaped block 309 is fixed above the outside of the mounting cylinder 302. A fixing rod 310 is slidably connected to the U-shaped block 309. The elastic force of the spring 312 pushes the fixing rod 310 into the adjustment hole 311 on the support rod 303, thereby locking the height of the support rod 303 inside the mounting cylinder 302. Pulling the pull rod 313 can cause the fixing rod 310 to disengage from the adjustment hole 311, releasing the height lock. At this time, the support rod 303 can be moved up and down to adjust the height. After adjustment, releasing the pull rod 313 will complete the locking. Compared with the traditional threaded adjustment method, the adjustment speed is faster and the operation is more convenient. A scale line 314 is provided on one side of the support rod 303; A scale line 314 is provided on one side of the support rod 303. When adjusting the height of the support rod 303, the operator can control the lifting distance of the support rod 303 by observing the reading of the scale line 314. The fixing mechanism 4 includes a rectangular plate 401 fixed at the upper end of the support rod 303, a worm gear 402 threadedly connected to the upper end of the rectangular plate 401, a rotating block 403 fixed at the lower end of the worm gear 402, and a lower pressure plate 404 fixed at the upper end of the worm gear 402. When the worm 402 is rotated, the worm 402 drives the rotating block 403 at the lower end to rotate using the principle of thread transmission. At the same time, the worm 402 moves up and down along the thread direction, which in turn drives the lower pressure plate 404 at the upper end to move up and down. When the lower pressure plate 404 moves down, it presses the workpiece to be processed, thereby fixing the workpiece. A light rod 405 is slidably connected to the upper end of the rectangular plate 401, and the upper end of the light rod 405 is fixedly connected to the lower pressure plate 404. The smooth rod 405 can effectively prevent the lower pressure plate 404 from deflecting during the lifting process, ensuring that the contact surface between the lower pressure plate 404 and the workpiece remains parallel, and improving the stability and reliability of clamping. Working principle: When adjusting the horizontal position, pull rod 308 to disengage the fixed rod 305 from the adjustment hole 306, releasing the lock. This pushes the moving block 301 along the T-plate 2 to the target position. Releasing pull rod 308 causes spring 307 to push the fixed rod 305 back into the corresponding adjustment hole 306, thus fixing the horizontal position and adapting to the processing position requirements of workpieces of different sizes. When adjusting the height, pull rod 313 to disengage the fixed rod 310 from the adjustment hole 311, releasing the lock. This moves the support rod 303 up and down. The operator can control the lifting distance via the scale line 314 on one side of the support rod 303. After adjusting to the target height, release pull rod 313. Spring 2 312 pushes the fixing rod 2 310 into the corresponding adjustment hole 2 311 to complete the height locking. Compared with the traditional threaded adjustment method, this height adjustment method is more convenient to operate and faster to adjust. When the worm gear 402 is rotated, the worm gear 402 drives the lower rotating block 403 to rotate while moving up and down along the thread direction, thereby driving the upper lower pressure plate 404 to rise and fall synchronously. When the lower pressure plate 404 moves down, it can press the workpiece to be processed placed on the worktable 1. The light rod 405 slidably connected to the upper end of the rectangular plate 401 is fixed to the lower pressure plate 404, which can effectively prevent the lower pressure plate 404 from deflecting during the lifting process, ensuring that the contact surface between the lower pressure plate 404 and the workpiece remains parallel, and improving the stability and reliability of workpiece clamping.
