Problems solved by technology
The ball of this quick clip device needs to be plugged into the first side hole on the first press sleeve through the first ball plug hole on the body. During the installation process, the first press sleeve should be prevented from detaching from the body. After the completion, it must be ensured that the diameter of the external tangent circle formed by multiple spheres is larger than the diameter of the smaller radial end of the first taper hole to prevent the first pressing sleeve from detaching from the body. The structure is complex and the assembly process is cumbersome.

Embodiment Construction
[0024] The present invention will be described in detail below in conjunction with the accompanying drawings.
[0025] Such as figure 2 and image 3 As shown, a quick clip device of the present invention includes a body 10 , a pressing sleeve 40 , an elastic element 50 and a ball 60 .
[0026] The body 10 plays the role of transmitting the torque of the rotating shaft 20 to the tool 30, one end of which is connected to the rotating shaft 20 for torque transmission, and the connection between the two can be through pins, couplings, or other transfer components Or detachable connection methods such as mechanisms can also be fixedly connected or integrally formed, as long as the body 10 and the rotating shaft 20 can be rigidly connected to transmit the torque to the body 10 and then to the tool 30, and the relationship between the two The connection mode is not a novelty of the present invention, and will not be described in detail here.
[0027] The other end of the body 10 ...

The invention relates to a quick clamping device, which comprises a body and a pressing cover, wherein the body is provided with an insertion hole and a tapered hole; the insertion hole is used for containing the top end part of a cutter handle part and transferring torque; the peripheral surface of the side wall of the pressing cover is provided with side holes; ball bodies are arranged in the side holes; when the cutter handle part is inserted into the pressing cover, the ball bodies support the cutter handle part and the hole wall of the tapered hole to realize cutter positioning; the outerwall of the pressing cover is convexly provided with extrusion parts; the excircle diameter of each extrusion part is greater than the diameter of the smaller end of the tapered hole so as to conveniently restrict a position, which is provided with the side hole, of the pressing cover in the tapered hole; and in an assembling process, a user only needs to slightly put forth strength to enable theextrusion part to realize elastic deformation, then, the pressing cover can be inserted into the body, and the position, which is provided with the side hole, of the pressing cover can be restrictedin the tapered hole without falling. The quick clamping device has a simple structure and can be conveniently assembled.
Description
technical field [0001] The invention relates to a tapping device, in particular to a quick-clamping device with the function of quickly changing tools, a multi-axis device, and a tapping machine. Background technique [0002] The quick clamping device is used to clamp the cutting tool and process the inner surface of the hole of various through holes or blind holes with different specifications on the parts to process the internal thread, screw or the clamp of the mechanical processing equipment called the tooth button. supporting institutions. At present, there are many types of quick-clamping devices on the market, but the structure is complex, the production cost is high, the processed thread has the problem of messy thread, and the precision is poor, and the tap is easy to break. [0003] Chinese Invention Patent Application Announcement CN204975582U discloses a quick clip device, such as figure 1 As shown, it includes a main body 10 and a first pressing sleeve 40, one...
