Referring to fig. 1, the present invention provides a cutting device for cutting a pipe 50. In one embodiment, the tube 50 may be a heat shrink.

In an embodiment of the present invention, the cutting device includes a frame 10, a cutter assembly 20, a rotary driving member 30 and a fixing assembly 40; wherein, the cutter component 20 is arranged on the frame 10; the rotary driving piece 30 is arranged on the frame 10; the fixing assembly 40 is connected to the rotary driving member 30, the fixing assembly 40 is used for limiting and fixing the pipe 50, and the fixing assembly 40 can also be driven by the rotary driving member 30 to rotate, so that the pipe 50 limited and fixed to the fixing assembly 40 rotates relative to the cutter assembly 20 to be cut by the cutter assembly 20.

In an embodiment of the present invention, the frame 10 can be mainly used for mounting and carrying the cutter assembly 20, the rotary driving member 30, and other parts of the cutting device, so that each part of the cutting device can form a whole body to facilitate carrying and managing the cutting device. The frame 10 may be made of plastic, for example: ABS (acrylonitrile-butadiene-styrene), POM (polyoxymethylene), PS (polystyrene), PMMA (polymethyl methacrylate), PC (polycarbonate), PET (polyethylene terephthalate), and the like; this reduces the mass of the frame 10 and further facilitates handling. Of course, in order to increase the supporting strength of the frame 10, the frame 10 may also be made of metal, such as: aluminum materials, aluminum alloy materials, copper alloy materials, iron materials, stainless steel materials and the like. The projection of the shape of the frame 10 on the horizontal plane may be substantially square, rectangular, or circular, etc. to make the shape of the frame 10 more regular and convenient for forming, but of course, the frame 10 may also be other shapes, and it is sufficient to mount and bear the cutter assembly 20, the rotary driving member 30, and other components of the cutting device. The cutting assembly 20 is mainly used for cutting the pipe 50 fixed to the fixing assembly 40 in a limited manner, so as to cut the long pipe 50 into a short pipe with a preset length. The rotary drive 30 may be used primarily to provide power to drive the rotation of the stationary assembly 40. The rotary drive 30 may be a motor. The fixing assembly 40 can be mainly used for performing limit fixing on the pipe 50, so that the pipe 50 which is limited and fixed on the fixing assembly 40 rotates relative to the cutter assembly 20 through rotation of the fixing assembly 40 to realize cutting.

The technical scheme of the utility model cutting device when cutting pipe fitting 50, carry out spacing fixed to pipe fitting 50 through fixed subassembly 40. Then the fixing assembly 40 is driven to rotate by the rotary driving member 30, so that the pipe 50 fixed to the fixing assembly 40 in a limited manner rotates relative to the cutter assembly 20 to be cut by the cutter assembly 20, thereby completing the cutting process of the pipe 50.

In addition, because the cutter assembly 20 of the cutting device in the scheme is limited and fixed, the cutter assembly 20 and the pipe fitting 50 can move relatively to cut through the rotation of the fixing assembly 40. The cutter assembly 20 does not need to move in the cutting process, the cutter assembly 20 is small in size, space is saved, and the fixing assembly 40 only needs to rotate to ensure a stable moving process. So compare in prior art cutting device's over-and-under type circular knife rotation cutting in the in-process that cuts pipe fitting 50, cutter 23 need go up and down simultaneously and make its stability that influences easily and cut the in-process and lead to pipe fitting 50's incision to have the burr in carrying out rotation process, cutting device's cutter unit 20 in this scheme can be comparatively stable and the incision that has reduced pipe fitting 50 has the possibility of burr phenomenon in the in-process that cuts pipe fitting 50. In addition, compared with a cutting device adopting lifting type cutting in the prior art, the cutting device in the scheme does not need to apply opposite shearing force to the cut of the pipe fitting 50, so that the phenomenon that the pipe orifice of the pipe fitting 50 after being cut is deformed and generates indentation due to extrusion deformation of the cut caused by the shearing force can be avoided. Therefore, the cutting device in the present scheme can improve the quality of the cut pipe 50, thereby improving the quality of the cut pipe 50.

Referring to fig. 1, fig. 2 and fig. 3, in an embodiment of the present invention, the fixing assembly 40 includes a clamping main body 41 and at least two clamping jaws 43, the clamping main body 41 is connected to the rotary driving member 30; at least two clamping jaws 43 are spaced apart from each other on the clamping body 41, and the at least two clamping jaws 43 can be moved toward each other to clamp the fixed tubular 50.

It can be understood that the fixing assembly 40 can realize the limiting and fixing of the pipe 50 by the at least two clamping jaws 43 connected to the clamping body 41 approaching to each other, and can realize the unlocking of the pipe 50 by the at least two clamping jaws 43 moving away from each other after the pipe 50 is cut. So can realize locking fast or unblock to pipe fitting 50 through comparatively simple mechanical mechanism to the convenience of the dismouting of pipe fitting 50 has been improved. The clamping body 41 may be in a ring shape, and at least two clamping jaws 43 surround the outer side of the ring opening of the clamping body 41. The tube 50 can now be inserted between at least two gripping dogs 43 from the side of the gripping body 41 facing away from the gripping dogs 43 by the collar of the gripping body 41, thereby further improving the ease of placement of the tube 50. Of course, in other embodiments, the clamping body 41 may also be a plate-shaped structure without a collar, and the pipe 50 may be inserted between the at least two clamping jaws 43 from an end of the at least two clamping jaws 43 away from the clamping body 41 to complete the installation. The number of the clamping claws 43 can be two, and the two clamping claws 43 are oppositely arranged; of course, the number of the clamping jaws 43 may be three or more, and the three or more clamping jaws 43 are evenly spaced around the center of the clamping body 41 to increase the clamping area of the outer circumferential surface of the pipe 50 to improve the stability of clamping and fixing the pipe 50. When the pipe 50 is cylindrical, at least the inner surface of the clamping jaw 43 is a curved surface so as to be attached to the outer wall surface of the pipe 50 to ensure the stability of clamping and fixing the pipe 50. Of course, when the pipe 50 has a square tubular shape, at least the inner surface of the holding claw 43 is a flat surface so as to be attached to the outer wall surface of the pipe 50. The application does not limit the specific shape and number of the clamping jaws 43, and can stably clamp and fix the pipe fitting 50. In addition, it should be noted that, the present invention is not limited to this, and in other embodiments, the fixing assembly 40 may include a suction fan and a suction plate, the suction plate has a wind cavity communicated with the suction fan, and a suction hole communicated with the wind cavity is further provided on a surface of the suction plate for contacting with the pipe 50, so that when the suction plate contacts with the pipe 50, the suction fan is activated to suck air between the suction plate and the pipe 50 through the suction hole and form a negative pressure, thereby achieving vacuum suction fixing of the pipe 50.

In an embodiment of the present invention, the fixing assembly 40 further includes a push ring 44, the push ring 44 is movably sleeved on the outer sides of the at least two clamping jaws 43, and the push ring 44 moves relative to the at least two clamping jaws 43 to drive the at least two clamping jaws 43 to deform and approach each other.

It can be understood that the at least two clamping jaws 43 are driven by the push ring 44 to approach each other by deformation so as to clamp and fix the pipe 50, so that the at least two clamping jaws 43 can be distributed relatively close to each other on the connecting body, which is beneficial to reduce the space occupied by the at least two clamping jaws 43 and reduce the overall volume of the fixing assembly 40. Meanwhile, the connecting structure of the clamping jaw 43 and the clamping main body 41 can be simplified by the arrangement, namely the clamping jaw 43 is limited and fixed on the clamping main body 41, and a relative sliding connection and other driving structures are not required to be arranged, so that the manufacturing cost of the fixing component 40 is reduced. Wherein the push ring 44 is moved relative to the at least two holding jaws 43 to drive the at least two holding jaws 43 to deform in the direction facing each other, the outer surfaces of the at least two holding jaws 43 may be formed with inclined surfaces, and the inner diameter of the push ring 44 is kept constant. When the push ring 44 moves in the direction close to the inclined surface relative to the at least two clamping jaws 43, the clamping jaws 43 are driven to deform towards the inner side by matching with the inclined surface, so that the pipe 50 is clamped and fixed; when the push ring 44 is then moved in a direction away from the inclined surface relative to the at least two gripping dogs 43, the gripping dogs 43 and the inclined surface disengage such that the gripping dogs 43 are reset towards the outside to unlock the tubular 50. Of course, in other embodiments, the fixing element 40 may be provided without the push ring 44, and at least two clamping jaws 43 may be disposed relatively close to each other, i.e. clamped and fixed by the pipe 50 when being elastically inserted into the at least two clamping jaws 43, and unlocked when being elastically pulled out from the at least two clamping jaws 43. Further, in order to improve the stability of the connection of the at least two clamping jaws 43 and the clamping body 41, the at least two clamping jaws 43 and the clamping body 41 may be an integral structure to improve the connection strength of the two at the connection position; meanwhile, the at least two clamping jaws 43 and the clamping main body 41 can be manufactured by integral molding, so that the processing technology of the two clamping jaws is simplified, and the production efficiency is improved. Of course, in other embodiments, at least two clamping jaws 43 may also be detachably connected to the clamping body 41, specifically may be screwed or snapped in.

It can be understood that the inner ring 441 is movably sleeved on the clamping claw 43, and includes two movement modes of the inner ring 411, namely, the relative rotation and the relative translation. At this time, the push ring 44 is composed of an inner snap ring 441 and an outer snap ring 443, so that the inner snap ring 441 moves relative to the clamping jaw 43 to drive the clamping jaw 43 to deform and clamp the pipe 50, and the outer snap ring 443 can be connected to the push ring driving member 45, and because the inner snap ring 441 and the outer snap ring 443 can rotate relative to each other, the inner snap ring 441 and the outer snap ring 443 are prevented from affecting the outer snap ring 443 and the push ring driving member 45 when rotating along with the clamping jaw 43. And the outer snap ring 443 is driven to move by the push ring driving piece 45, so that the automation degree of the cutting device is improved without manual operation of a worker. The push ring driving member 45 may be a cylinder or a linear motor, and it is only required to drive the outer snap ring 443 to perform linear motion. The number of the push ring driving members 45 may be one, or may be two, and further, in order to improve the smoothness of the inner snap ring 441 and the outer snap ring 443 in the movement process, a first bearing 445 may be sleeved between the inner snap ring 441 and the outer snap ring 443.

It can be understood that, by rotatably providing the clamping body 41 on the mounting plate 46, the clamping body 41 can be better supported by the mounting plate 46, so that the stability of the installation of the clamping body 41 can be improved. The push ring driving member 45 is mounted on the mounting plate 46, so that the installation between the push ring driving member 45 and the clamping body 41 can be more compact, and the overall size of the cutting device can be further reduced, thereby reducing the occupied space. Further, in order to reduce the resistance of the clamping body 41 during the rotation, the fixing assembly 40 may further include a rotating shaft sleeve 47, the rotating shaft sleeve 47 is sleeved outside the clamping body 41, a gap is formed between an inner side wall of the rotating shaft sleeve 47 and an outer side wall of the clamping body 41, the rotating shaft sleeve 47 is further rotatably connected to the mounting plate 46 and connected to the rotary driving member 30, and an end portion of one end of the clamping body 41, which is away from the clamping jaw 43, extends outward to form a flange to connect with the rotating shaft sleeve 47. In order to improve the smoothness of the rotation between the rotation sleeve 47 and the mounting plate 46, a second bearing 48 may be inserted between the rotation sleeve 47 and the mounting plate 46.

It can be understood that the guide column 461 and the guide sleeve 4431 are matched to guide the moving stroke of the outer snap ring 443, so that the outer snap ring 443 can only move along the extending direction of the guide column 461 when being driven to move by the push ring driving element 45, thereby ensuring the stability of the outer snap ring 443 in the moving process, so that the inner snap ring 441 can accurately drive the clamping jaw 43 to deform and stably clamp the fixed pipe 50. Wherein, the mounting plate 46 may be provided with a guide post 461, and the outer snap ring 443 is provided with a guide sleeve 4431; of course, the mounting plate 46 may be provided with the guide sleeve 4431 and the outer clamp ring 443 may be provided with the guide posts 461. In addition, the guide column 461 and the guide sleeve 4431 can be detachably fixed by screws or buckles, so that the guide column can be detached for maintenance and replacement when the guide column is damaged. The guide sleeve 4431 may be a linear bearing or a common guide sleeve, which is not limited in the present application, and the moving process of the outer snap ring 443 can be guided.
