[0034] Example 1

[0035] Reference Figure 1-10 As shown in the figure, in order to realize the rapid installation and disassembly of the threading die head, greatly simplify the installation and disassembly process, and improve processing efficiency, this embodiment proposes a rapid installation and disassembly structure for the threading die head, including a main body 100, a quick-release assembly 200 and a threading die head 300. The main body 100 is the main body of the threading machine, which is used to carry the quick-release assembly 200 and the threading die head 300, and perform the routine work of the threading machine. It is not difficult to understand that the main body 100 is provided with electronic components and related parts for the existing threading machine to carry out work. This embodiment only focuses on the rapid installation and disassembly of the threading die head 300, because what is needed on the main body 100 is only the structure for cooperating with the installation and disassembly of the threading die head, so other parts are not described in detail. The threading die head 300 is installed in the main body 100, and quick installation and disassembly are achieved through the structure of the quick-release assembly 200.

[0036] Furthermore, the main body 100 includes a body 101, a back cover 102 and a cavity 103. The back cover 102 is arranged to cover the body 101. The tooth pieces 104 are arranged in the cavity 103. Tooth grooves 105 are formed between adjacent tooth pieces 104. The cavity 103 is an inwardly concave circular groove.

[0037] The quick-release assembly 200 includes an inner ring body 201, teeth 202, a receiving ring body 203, a rotating ring body 204, a locking pin 205, a mounting cavity 206, and a locking assembly 207. The teeth 202 are arranged on the outer annular surface of the inner ring body 201 and mesh with the tooth grooves 105. The receiving ring body 203 extends along the side of the inner ring body 201 to form a limited space s. The locking assembly 207 is disposed in the limited space s, and the rotating ring body 204 is disposed on the side of the locking assembly 207 and pressed tightly. It should be noted that the meshing of the teeth 202 and the tooth grooves 105 not only serves to fix the inner ring body 201, but also limits the rotation of the inner ring body 201. The locking assembly 207 is disposed in the limited space s and is limited by the rotating ring body 204 on the side. The threading die head 300 includes a limiting groove 301 . The threading die head 300 is embedded in the installation cavity 206 and can be installed and disassembled by correspondingly clamping and disengaging between the limiting groove 301 and the locking pin 205 .

[0038] More specifically, in this embodiment, the locking assembly 207 includes a sliding slot 207a, a first pin hole 207b, a spring 207c, and a sliding member 207d. The locking pin 205 and spring 207c are positioned within the first pin hole 207b, and the sliding member 207d is positioned within the sliding slot 207a. The first pin hole 207b is hollowed out on one side within the sliding slot 207a. The sliding slot 207a is provided with a sliding plane 207a-1 and a sliding side surface 207a-2. The sliding member 207d slides against the sliding plane 207a-1 and the sliding side surface 207a-2.

[0039] To cooperate with the limitation, the locking pin 205 in this embodiment includes a top surface 205a, a limiting surface 205b, a protrusion 205c and a bottom surface 205d; the locking pin 205 is located in the first pin hole 207b and slides up and down, and the spring 207c is arranged between the bottom surface 205d and the inner ring wall of the accommodating ring body 203. The locking pin 205 moves inward under the squeezing force of the spring 207c and is limited outward by the limiting surface 205b.

[0040] A contact surface 207b-1 is provided within the first pin hole 207b, and the limiting surface 205b is configured to contact the contact surface 207b-1. The top surface 205a is coplanar with the inner ring wall of the receiving ring body 203. The sliding member 207d includes a long strip 207d-1 and a limiting portion 207d-2. The limiting portion 207d-2 slides along the sliding plane 207a-1. Once the bottom surface 205d is coplanar with the sliding plane 207a-1, the limiting portion 207d-2 can contact the bottom surface 205d, preventing the locking pin 205 from moving.

[0041] In this embodiment, in order to realize the sliding of the sliding member 207d by the rotating ring body 204, the rotating ring body 204 also includes a bayonet 204a, a sliding column groove 204b and a toggle portion 204c; the long strip 207d-1 is embedded in the bayonet 204a, and can be manually toggled by the toggle portion 204c until the rotating ring body 204 rotates, thereby driving the sliding member 207d to slide in the sliding groove 207a. The toggle portion 204c increases friction and is set to an undulating wave-like protrusion to facilitate manual toggle.

[0042] As a preferred embodiment of this embodiment, regarding the fixing solution, the locking assembly 207 further includes a fixing pin 207e and a second pin hole 207f. A fixing hole 201a is provided on the side of the inner ring body 201 to cooperate with the fixing pin 207e. The fixing pin 207e passes through the second pin hole 207f and is fixed to the fixing hole 201a. The locking assembly 207 further includes a gasket 207g, which is disposed on one side of the rotating ring body 204. The fixing pin 207e passes through the gasket 207g, the sliding column slot 204b, and the second pin hole 207f in sequence, and is fixed to the fixing hole 201a. The fixing pin 207e slides within the sliding column slot 204b.

[0043] For ease of understanding, the disassembly and assembly process of the threading die head 300 of this embodiment is as follows:

[0044] When the threading die 300 is aligned with the cavity 103, and then pushed in, the toggle portion 204c of this embodiment is manually toggled to rotate. At this time, the limiting effect of the long strip 207d-1 embedded in the bayonet 204a drives the sliding member 207d in the locking assembly 207 to slide until the sliding member 207d is no longer above the bottom surface 205d. At this time, the locking pin 205 is located in the first pin hole 207b and can slide inward and outward. The inward movement is not limited by the sliding member 207d, that is, the locking pin 205 can be retracted inward under the compression spring 207c, and the protrusion 205c is retracted into the inner surface wall of the locking assembly 207. At this time, the threading die 300 can move on both sides. In this state, the threading die 300 is installed inward to squeeze the locking pin 205. When it is disassembled, the locking pin 205 pops out under the elastic force of the spring 207c, and reaches a detachable state.

[0045] When the threading die head 300 is installed in place, the locking pin 205 falls into the limiting groove 301 and reaches the maximum moving stroke under the action of elastic force. At this time, the bottom surface 205d is coplanar with the sliding plane 207a-1, the conflicting surface 207b-1 conflicts with the limiting surface 205b, and the top surface 205a is coplanar with the inner surface wall of the locking component 207. At this time, the locking installation operation can be started, and the toggle part 204c of this embodiment is manually toggled in the reverse direction to rotate. The limiting effect of the long strip 207d-1 embedded in the bayonet 204a drives the sliding part 207d in the locking component 207 to slide until the sliding part 207d is above the bottom surface 205d. In this state, the limiting part 207d-2 conflicts with the bottom surface 205d until the locking pin 205 cannot move, thereby realizing the locking of the locking pin 205 falling into the limiting groove 301, and the installation is completed.

[0046] When disassembly is required, the toggle portion 204c of this embodiment is manually toggled in the opposite direction again. The limiting action of the long strip 207d-1 embedded in the bayonet 204a drives the sliding member 207d in the locking assembly 207 to slide until the sliding member 207d is above the bottom surface 205d. At this time, the locking pin 205 can jump up and down under the action of the elastic force. Due to the guide surface provided by the protrusion 205c, the locking pin 205 is squeezed inward by the guide surface when the threading die 300 is pulled out. After the locking pin 205 is released from the limiting groove 301, the locking pin 205 is restored to the maximum outward travel position under the action of the elastic force, waiting for the next installation. In this way, the threading die 300 can be quickly installed and disassembled.

[0047] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. The embodiments should be considered as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the foregoing description. It is intended that all variations within the meaning and range of equivalents of the claims be encompassed within the present invention, and any reference signs in the claims should not be construed as limiting the claims to which they relate.
