DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1

[0024] like Figure 1-5 As shown, the utility model provides a positioning fixture for a milling machine that is easy to install, including: a milling machine fixture base 1; a milling machine fixture clamping device 2, which is arranged on the base 1 and is used to clamp a workpiece for processing; a milling machine fixture lifting device 3, which is arranged on the base 1 and is used to lift the base 1 to adapt to people of different heights; the milling machine fixture, wherein the clamping device 2 includes: a milling machine fixture spring device 21, which is arranged on the base 1 and is used to clamp the workpiece; a milling machine fixture sliding device 22, which is arranged on the base 1 and is used to limit the clamping device 2 to prevent deviation and affect the processing accuracy.

[0025] The spring device 21 includes a fixed block 211, a pull rod 212, a pull ring 213, and a spring 214. The fixed block 211 is fixedly connected to the top of the base 1, the pull rod 212 movably passes through the fixed block 211, and the right side of the pull rod 212 is fixedly connected to the left side of the clamping block 221, the pull ring 213 is fixedly connected to the left side of the pull rod 212, and the spring 214 is movably sleeved on the outer wall of the pull rod 212, and the two ends of the spring 214 are respectively fixedly connected between the fixed block 211 and the clamping block 221. The spring 214 is a compression spring. The compression spring is easy to manufacture and process, has low cost, and can be applied to different shapes, sizes and load requirements, so it has high applicability. The compression spring has a compression force and can apply force in the vertical direction.

[0026] The sliding device 22 includes a clamping block 221, a slide groove 222, and a slider 223. The slide groove 222 is opened at the top of the base 1, and the slider 223 is slidably connected to the inner wall of the slide groove 222. The clamping block 221 is fixedly connected to the top of the slider 223. The slider 223 and the slide groove 222 are T-shaped, which can well prevent the clamping block 221 from running off, thereby reducing the processing accuracy. The slider 223 is cast in an integrated manner, which improves the integrity. There is no interface inside, and there is no weakness problem at the interface. No assembly is required, and it can be directly installed, which is convenient for production and maintenance.

[0027] In this embodiment, by pulling the pull ring 213, the pull ring 213 drives the fixedly connected pull rod 212, and the pull rod 212 drives the clamping block 221 on the right side. When the clamping block 221 moves, it drives the slider 223 fixedly connected to the bottom. The slider 223 slides on the inner wall of the slide groove 222 to limit the clamping block 221 and prevent the clamping block 221 from deviating during the movement. At the same time, when the pull rod 212 drives the clamping block 221 to move, the clamping block 221 will compress the spring 214 between the clamping block 221 and the fixed block 211, and the workpiece to be processed is placed on the top of the base 1. The pull ring 213 is released, and the spring 214 is not compressed, which will drive the clamping block 221 and the pull rod 212 to move to the left to clamp the workpiece.

[0028] Example 2

[0029] like Figure 1-5As shown, on the basis of embodiment 1, the utility model provides a technical solution: the lifting device 3 includes a lifting assembly 31, a transmission device 32, and an adjustment mechanism 33. The lifting assembly 31 is arranged on the base 1, the transmission device 32 is arranged on the base 1, and the adjustment mechanism 33 is arranged on the base 1. The lifting assembly 31 includes a support leg 311, a support plate 312, a motor box 313, a motor 314, and a worm 315. The support leg 311 is connected to the outer wall of the sliding rod 332, and the support plate 312 is fixedly connected to the back of the support leg 311. The motor box 313 is connected to the bottom of the support plate 312, the motor 314 is fixedly connected to the bottom of the inner wall of the motor box 313, the worm 315 is rotatably connected to the top of the support plate 312 through the bearing, and movably extends downward through the support plate 312, and its extended end is fixedly connected to the output end of the motor 314. The bearing is a ball bearing, which can bear radial and axial loads, and can bear composite loads at the same time. The ball bearing and the shaft are matched using interference fit or clearance fit, which is more convenient to install and the force direction is relatively stable, so the installation error has little effect on it.

[0030] The transmission device 32 includes a support block 321, a rotating rod 322, and a worm gear 323. The support block 321 is fixedly connected to the top of the support plate 312, the worm gear 323 is fixedly sleeved on the outer wall of the rotating rod 322, and the rotating rod 322 is rotatably connected to the support block 321 through a bearing.

[0031] The adjusting mechanism 33 includes a moving fork 331, a sliding rod 332, and a pulley 333. The moving fork 331 is fixedly sleeved on the outer wall of the rotating rod 322, the sliding rod 332 is slidably connected to the inner wall of the supporting leg 311, and the pulley 333 is hinged at the bottom of the sliding rod 332. The pulley 333 is made of rubber and has good friction performance. It can avoid the problem of unstable sliding of the pulley or shaking during rolling, thereby improving the stability of use. It has strong shock absorption ability, can absorb the impact force when the object moves, avoid damage to mechanical hardware, and improve the service life of the equipment. It has good wear resistance and can reduce the wear on the roller surface. At the same time, it can also effectively reduce damage to the device and extend the service life of the equipment. The appearance shape and internal structure have good deformation ability and can adapt to complex environments and working conditions, including different temperatures, humidity, movement speeds, wear degrees and other factors. It can play a stabilizing role in various occasions.

[0032] In this embodiment, by starting the motor 314 fixedly connected to the bottom of the inner wall of the motor box 313, the motor 314 drives the worm 315, the rotation of the worm drives the two worm wheels 323 to rotate, the rotation of the worm wheel 323 drives the rotating rod 322 to rotate, the rotation of the rotating rod 322 drives the moving fork 331 fixedly mounted on the outer wall, when the moving fork 311 moves upward, its inner wall slides on the outer wall of the pulley 333 hinged at the bottom of the sliding rod 332, driving the sliding rod 332 to move upward and adjust to a suitable height.

[0033] The following is a detailed description of the working principle of this easy-to-install positioning fixture for milling machines.

[0034] like Figure 1-5 As shown, when in use, the pull ring 213 is pulled, and the pull ring 213 drives the fixedly connected pull rod 212, and the pull rod 212 drives the clamping block 221 on the right side. When the clamping block 221 moves, it drives the slider 223 fixedly connected at the bottom, and the slider 223 slides on the inner wall of the slide groove 222 to limit the clamping block 221 to prevent the clamping block 221 from deviating during the movement. At the same time, when the pull rod 212 drives the clamping block 221 to move, the clamping block 221 will compress the spring 214 between the fixed block 211, and the workpiece to be processed is placed on the top of the base 1, and the pull ring 213 is released. The spring 214 is pressed. When not under pressure, the clamp block 221 and the pull rod 212 will move to the left to clamp the workpiece. When the height needs to be adjusted, the motor 314 fixedly connected to the bottom of the inner wall of the motor box 313 is started, and the motor 314 drives the worm 315. The rotation of the worm drives the two worm wheels 323 to rotate. The rotation of the worm wheel 323 drives the rotating rod 322 to rotate. The rotation of the rotating rod 322 drives the moving fork 331 fixedly mounted on the outer wall. When the moving fork 311 moves upward, its inner wall slides on the outer wall of the pulley 333 hinged at the bottom of the sliding rod 332, driving the sliding rod 332 to move upward and adjust to a suitable height.
