Detailed Description

The embodiment of the application discloses stable milling machine of centre gripping. Referring to fig. 1, a clamp-stabilized milling machine includes a milling machine body 1, a clamp assembly 2, and a plexor 3. The milling machine body 1 is used for milling a workpiece; the clamping assembly 2 is used for clamping and fixing the workpiece, so that the workpiece is not easy to move in the machining process; the knocking member 3 is used for improving the fastening of the workpiece to be clamped.

Referring to fig. 2, the clamping assembly 2 includes a fixing frame 21 fixedly connected to the milling machine body 1, and the fixing frame 21 is horizontally disposed and has a frame-shaped structure as a whole. A horizontally arranged worm 22 is rotatably arranged in the fixing frame 21, and one end of the worm 22 passes through the fixing frame 21 and extends to the outer side of the fixing frame 21. One end of the worm 22 extending to the outside of the fixed frame 21 is fixedly connected with a rotating handle 23, the cross section of the rotating handle 23 is rectangular, and two side surfaces far away from one end of the worm 22 are both connected with reinforcing plates 231. The rigidity of the reinforcing plate 231 is greater than the rigidity of the turning handle 23, so that the strength of the turning handle 23 is improved, and the service life of the turning handle 23 is prolonged.

Referring to fig. 2, a ratchet mechanism 4 is disposed between the rotating handle 23 and the fixing frame 21, and the ratchet mechanism 4 includes a ratchet 41 connected to the worm 22 and a pawl 42 rotatably connected to the fixing frame 21. Referring to fig. 3, a limiting plate 211 slidably disposed on the fixing frame 21 is disposed on one side of the pawl 42, and the limiting plate 211 is disposed horizontally. Specifically, the fixing frame 21 is provided with a sliding groove for inserting the limiting plate 211, and after the worker disengages the pawl 42 from the ratchet wheel 41, the limiting plate 211 is slid, and the pawl 42 is lapped on the upper surface of the limiting plate 211, so that the rotation of the worm 22 is not easily influenced by the pawl 42.

Referring to fig. 2, the striking member 3 is used for striking the turning handle 23, the striking member 3 includes a clamping rod 31 and a hammer head 32, and the hammer head 32 is fixedly connected with one end of the clamping rod 31. The side of the clamping rod 31 far away from the hammer head 32 is made into a round rod shape, i.e. the radius of the end of the clamping rod 31 far away from the hammer head 32 is smaller than the radius of the end of the clamping rod 31 near the hammer head 32. Referring to fig. 3, the lower surface of the pawl 42 is provided with a limit groove 43 for inserting one end of the clamping rod 31 away from the hammer head 32. When the worker needs to disengage the ratchet 42 from the ratchet 41, the end of the clamping rod 31 having the shape of a circular rod is inserted into the stopper groove 43, and then the end of the clamping rod 31 having the shape of a circular rod is moved upward, so that the ratchet 42 can be disengaged from the ratchet 41. The limiting groove 43 limits the clamping rod 31, and helps to prevent the clamping rod 31 from sliding along the lower surface of the pawl 42, so that the efficiency is affected.

Referring to fig. 2, a sliding block is connected to the worm 22 through a thread, a first clamping plate 24 is fixedly connected to the upper end of the sliding block, and both sides of the lower surface of the first clamping plate 24 are abutted to the upper surface of the fixing frame 21. The worker rotates the worm 22 to move the slider in a lengthwise direction of the worm 22, thereby moving the first clamping plate 24 to follow the slider. A second clamping plate 25 fixedly connected with the fixed frame 21 is arranged on one side of the first clamping plate 24 far away from the rotating handle 23. When the worker rotates the worm 22 by rotating the handle 23 to move the first clamping plate 24 to a direction close to the second clamping plate 25, the ratchet wheel 41 and the pawl 42 do not influence the rotation of the worm 22; when the first clamping plate 24 is moved in a direction away from the second clamping plate 25, the ratchet wheel 41 and the pawl 42 restrict the worm 22 so that the worm 22 is not easily rotated. A plurality of grooves 26 are formed on the side surface of the first clamping plate 24 close to the second clamping plate 25 and the side surface of the second clamping plate 25 close to the first clamping plate 24.

The implementation principle of the milling machine with stable clamping in the embodiment of the application is as follows: the worker inserts the end of the striking member 3 having a round bar shape into the stopper groove 43 and then pries the pawl 42 to disengage the pawl 42 from the ratchet 41. Then, the stopper plate 211 is moved in a direction to approach the ratchet 42, and the ratchet 42 is caught on the stopper plate 211. The rotating handle 23 is then rotated to move the first clamping plate 24 away from the second clamping plate 25. The rotation handle 23 is stopped after the distance between the first and second holding plates 24 and 25 can accommodate the workpiece, and the workpiece is inserted between the first and second holding plates 24 and 25.

The stopper plate 211 is moved in the reverse direction to engage the pawl 42 with the ratchet 41. The rotating handle 23 is rotated in the reverse direction to move the first holding plate 24 in a direction to approach the second holding plate 25, thereby clamping the workpiece between the first holding plate 24 and the second holding plate 25. Finally, the knocking member 3 is used, and the hammer head 32 is used for striking the reinforcing plate 231 to fasten the worm 22. The worm 22 is limited by the ratchet wheel 41 mechanism 4, so that the movement is not easy to occur, the stability of workpiece processing is ensured, and the processing quality is improved.

The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
