Description
Technical Field
The invention belongs to the technical field of machine tool machining, and particularly relates to a disengagement protection device.
Background
When a machine tool is used for processing a short shaft part, the short shaft part is required to have a required extending length after being clamped into a chuck, if the extending length is not enough, the whole part is not in accordance with the size requirement, the blank size of the short shaft part is short, and after clamping is finished, if the feeding amount of a tool is wrong, the tool is easy to collide with the chuck of the machine tool, so that potential safety hazards exist.
Disclosure of Invention
The invention aims to provide a disengagement protection device, which avoids the cutter collision accident caused by the fact that a short shaft part touches a cutter during machining. In order to achieve the purpose, the invention adopts the following technical scheme:
a throw-off protection device is matched with a polished rod for use and comprises a hollow sleeve, a connecting shaft, a driven shaft, a compression spring, an adjusting sleeve and an adjusting screw;
one end of the hollow sleeve is fixed on the output gear shaft, and the other end of the hollow sleeve is fixed with the connecting shaft through a pin shaft;
the first end part of the connecting shaft, which is back to the hollow sleeve, is propped against and matched with the second end part of the driven shaft, which is towards the connecting shaft; the driven shaft is provided with a key slot;
the compression spring is sleeved on the driven shaft and abuts against the second end part;
the first end part and the second end part are clamped in the adjusting sleeve; the adjusting screw props against the compression spring and is clamped on the end face of the adjusting sleeve.
Preferably, the diameter of the first end portion is larger than the diameter of the connecting shaft toward the hollow housing portion.
Preferably, the diameter of the second end part is larger than that of the key slot part of the driven shaft.
Preferably, the mating surface of the first end portion is a curved surface.
Preferably, a sealing ring is arranged at one end, facing the hollow sleeve, of the connecting shaft.
Preferably, the pin is a resilient cylindrical pin.
Compared with the prior art, the invention has the beneficial effects that: the connecting shaft and the driven shaft are disconnected through the compression spring, so that the cutter collision accident caused by the fact that the short shaft part touches the cutter during machining is avoided.

Detailed Description
The trip protection device of the present invention will now be described in more detail with reference to the schematic drawings, in which preferred embodiments of the invention are shown, it being understood that a person skilled in the art may modify the invention described herein while still achieving the advantageous effects of the invention. Accordingly, the following description should be construed as broadly as possible to those skilled in the art and not as limiting the invention.
As shown in figures 1-2, a trip protection device is used in conjunction with a polish rod 12, wherein a slide carriage box is arranged on the polish rod 12, and a cutter head is arranged on the slide carriage box. The disengagement protection device is mounted on the output end (output gear 2 shaft) of the machine tool gearbox. Normally, the gearbox, the trip protection device and the polished rod 12 rotate and are sequentially driven to realize the feeding motion of the tool rest. When the slide carriage or the feeding amount is too large, the internal transmission of the disconnection protection device is disconnected, so that the disconnection protection device interrupts the transmission between the gearbox and the polished rod 12, the polished rod 12 cannot rotate further, and the tool rest is protected. Specifically, the structure of the trip protection device is as follows:
comprises a hollow sleeve 1, a connecting shaft 8, a driven shaft 10, a compression spring 7, an adjusting sleeve 4 and an adjusting screw 5.
Wherein, one end of the hollow sleeve 1 is sleeved and fixed on the output gear 2, and the other end is fixed with the connecting shaft 8 through a pin shaft.
The first end of the connecting shaft 8, which is back to the hollow sleeve 1, is abutted against and matched with the second end of the driven shaft 10, which is towards the connecting shaft 8.
The driven shaft 10 is provided with a key slot 9 which is matched with a connecting key 11 on a polished rod 12, and the polished rod 12 axially passes through a spring and an adjusting screw 5, extends out of the release protection device and is connected with the slide carriage box; meanwhile, the polished rod 12 and the adjusting screw 5 are fixed through a pin.
The compression spring 7 is sleeved on the driven shaft 10 and abuts against the second end part.
The first end part and the second end part are clamped in the adjusting sleeve 4; the adjusting screw 5 is propped against the compression spring 7 and clamped on the end surface of the adjusting sleeve 4. When the slide carriage or the feeding amount is too large, the compression spring 7 is further compressed, the first end part and the second end part are separated, the internal transmission of the disengagement protection device is disengaged, the smooth rod stops rotating, and the cutter stops feeding.
In the embodiment, the diameter of the first end part is larger than that of the part of the connecting shaft 8 facing the hollow sleeve 1, and the diameter of the second end part is larger than that of the part of the driven shaft 10 provided with the key groove 9; the matching surface of the first end part is a curved surface.
In the present embodiment, the connecting shaft 8 is provided with a sealing ring 6 towards one end of the hollow sleeve 1.
In this embodiment, the pin 3 is a resilient cylindrical pin.
The working principle of the invention is as follows:
normally, the gearbox, the trip protection device and the polished rod 12 rotate and are sequentially driven to realize the feeding motion of the tool rest. When the slide carriage or the feeding amount is too large, the compression spring 7 is further compressed, the first end part and the second end part are separated, the internal transmission of the disengagement protection device is disengaged, the smooth rod stops rotating, and the cutter stops feeding.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
