Description
Technical Field
[0001] The utility model belongs to the technical field of milling machine clamps, and in particular relates to a side clamp shock absorbing structure of a milling machine. Background Art
[0002] A milling machine is a machine tool that uses a milling cutter to mill workpieces. In addition to milling planes, grooves, gear teeth, threads and spline shafts, milling machines can also process more complex surfaces. They are more efficient than planers and are widely used in machinery manufacturing and repair departments.
[0003] With the development of the manufacturing industry, higher requirements are placed on the processing efficiency and precision of parts. Among the milling machine fixtures currently used, for shaft parts, when the parts are milled on the milling machine, the clamped parts on the milling machine are clamped and fixed, and the parts are processed by the rotation of the milling cutter. However, when the clamped parts are milled, since most of the milled parts are metal, the milling cutter uses a large force, and the clamped parts are prone to shaking due to vibration, which is inconvenient to use, affecting the milling effect and reducing work efficiency.

[0007] The technical effects of a side clamp shock-absorbing structure of a milling machine provided by the utility model are as follows: a driving motor drives the threaded rod to rotate, so as to drive the two threaded blocks to move toward the middle on the threaded rod, so as to facilitate the clamping block fixedly connected to the threaded block to clamp the component; by setting a shock-absorbing mechanism, it is convenient to clamp the component on the milling machine, and when the milling cutter drills the component, strong vibration is avoided to cause the component to deviate, and the shock-absorbing mechanism is used for buffering, and the component is damaged due to the force clamping. During operation, when the component moves, the telescopic rod retracts, the first spring is compressed, and at the same time, the first connecting rod and the second connecting rod cooperate to push the slider to be squeezed toward the two sides of the through hole. Due to the cooperation of the second spring, the second spring is compressed and rebounds under the elastic force of the second spring, thereby pushing the slider back to the initial position, thereby driving the first spring back to the initial position, buffering and shock-absorbing the component.
[0008] Wherein, the thread block is arranged in an L shape.
[0009] On the basis of the above technical solution, the side clamp shock absorbing structure of a milling machine of the utility model can also be improved as follows:
[0010] Furthermore, it also includes a second spring, which is arranged in the second through hole, one end of the second spring is fixedly connected to the inner wall of the second through hole, and the other end of the second spring is fixedly connected to the sliding block.
[0011] Furthermore, the number of the first connecting rods and the number of the second connecting rods are both four.
[0012] Furthermore, the number of the sliders is set to two, and every two of the first connecting rods and the second connecting rods are rotatably connected to each of the sliders.
[0013] The beneficial effect of adopting the above further solution is: by arranging two of the first connecting rods and the second connecting rods on each slider, the slider can slide more stably in the through hole and prevent the slider from falling out of the through hole.
[0014] Furthermore, an elastic rubber pad is fixedly connected to the clamping block, and the elastic rubber pad is made of rubber material.
[0015] The beneficial effect of adopting the above further solution is: by providing an elastic rubber pad, the friction between the clamping block and the clamped component can be increased, so that the clamping is more stable.
[0016] Furthermore, the threaded rod is a bidirectional threaded rod, and the number of the threaded blocks is set to two.
[0017] Compared with the prior art, the beneficial effects of the side clamp shock-absorbing structure of a milling machine provided by the utility model are: by driving the threaded rod to rotate through a driving motor, it is convenient to drive the two threaded blocks to move toward the middle on the threaded rod, so that the clamping block fixedly connected to the threaded block is convenient to clamp the component; by setting the shock-absorbing mechanism, it is convenient to clamp the component on the milling machine, and when the milling cutter drills the component, it is avoided that the strong vibration causes the component to deviate, and the shock-absorbing mechanism is used for buffering, and the component is damaged due to the force clamping. During operation, when the component moves, the telescopic rod retracts, the first spring is compressed, and at the same time, the first connecting rod and the second connecting rod cooperate to push the slider to be squeezed to both sides of the through hole. Due to the cooperation of the second spring, the second spring is compressed and rebounds under the elastic force of the second spring, thereby pushing the slider back to the initial position, thereby driving the first spring back to the initial position, buffering and shock-absorbing the component.

[0025] like Figure 1-2 As shown, the utility model provides a milling machine side clamp shock absorbing structure, which includes a base 10, a driving motor 21, a threaded rod 31, a threaded block 32 and a shock absorbing mechanism. The base 10 is provided with a first through hole 11, the driving motor 21 is fixedly installed on the side wall of the base 10, the output shaft of the driving motor 21 is fixedly connected to one end of the threaded rod 31, and drives the threaded rod 31 to rotate, the other end of the threaded rod 31 is rotatably installed on the inner wall of the base 10, the threaded block 32 is threadedly connected to the threaded rod 31, and a shock absorbing mechanism is arranged on the threaded block 32, and the shock absorbing mechanism includes a connecting frame 40, a connecting block 41, a sliding block 42, and a telescopic rod 50, a clamping block 60, a first spring 70, a first connecting rod 91 and a second connecting rod 92, one end of the telescopic rod 50 is fixedly connected to the threaded block 32, and the other end is fixedly connected to the clamping block 60, the connecting frame 40 is fixedly connected to the threaded block 32 outside the telescopic rod 50, and the connecting block 41 is fixedly connected to the connecting frame 40, a through hole is provided on the connecting block 41, and a slider 42 is arranged in the through hole, one end of the first connecting rod 91 is hinged to the threaded block 32, and the other end is hinged to the slider 42, one end of the second connecting rod 92 is hinged to the clamping block 60, and the other end is hinged to the slider 42, and a first spring 70 is sleeved on the outside of the telescopic rod 50.
[0026] The thread block 32 is arranged in an L shape.
[0027] Optionally, in the above technical solution, a second spring 80 is further included. The second spring 80 is arranged in the second through hole. One end of the second spring 80 is fixedly connected to the inner wall of the second through hole, and the other end is fixedly connected to the slider 42.
[0028] Optionally, in the above technical solution, four first connecting rods 91 and four second connecting rods 92 are provided.
