Description

Technical Field

[0001] The utility model relates to the field of pipe cutting machines, in particular to a feeding device for pipe cutting machines. Background Art

[0002] The pipe cutting machine is a mechanical device specially used for cutting pipes, and is commonly used for processing materials such as metal pipes, plastic pipes, and composite pipes. It has the advantages of high efficiency, precision, safety, and easy operation, and is widely used in manufacturing, construction, pipeline installation, mechanical processing, and other fields. The pipe cutting machine generally includes a frame, a cutting system, a feeding system, a control system, a power supply system, etc. The feeding system is a device used to feed the pipe to be cut into the cutting system, which is generally also called a feeding device.

[0003] Existing feeding devices usually include clamping mechanisms, conveyor belts, rollers or sliders, etc., which can complete automatic feeding of pipes. However, after a pipe is cut, the tail pipe left after cutting, that is, the last section of the pipe, often does not meet the required size. In the prior art, the tail pipe is generally handled by manually removing it from the chuck and then placing it in a collection box. However, this method is inconvenient, and the incision temperature of the pipe that has just been cut is high. Manually removing the tail pipe may also burn the worker. If the tail pipe is removed after cooling for a period of time, a certain waiting time is required, which reduces production efficiency. Alternatively, the chuck is loosened, causing the tail pipe to automatically fall into the collection box of pipes that meet the size, which is easy to cause confusion. Finally, it still needs to be picked out manually. In order to solve the above problems, a feeding device for a pipe cutting machine is proposed. Utility Model Content

DETAILED DESCRIPTION

[0022] Various exemplary embodiments, features and aspects of the present application will be described in detail below with reference to the accompanying drawings. The same reference numerals in the accompanying drawings represent elements with the same or similar functions. Although various aspects of the embodiments are shown in the accompanying drawings, the drawings are not necessarily drawn to scale unless otherwise specified.

[0023] The word “exemplary” is used exclusively herein to mean “serving as an example, example, or illustration.” Any embodiment described herein as “exemplary” is not necessarily to be construed as preferred or advantageous over other embodiments.

[0024] In addition, in order to better illustrate the present application, numerous specific details are provided in the specific embodiments below. It should be understood by those skilled in the art that the present application can also be implemented without certain specific details. In some examples, methods, means, and elements well known to those skilled in the art are not described in detail in order to highlight the subject matter of the present application.

[0025] Example 1, please refer to Figure 1-Figure 5The structure shown in the utility model embodiment, a feeding device for a pipe cutting machine includes a frame 1, a positioning fixture 2 slidably mounted on the frame 1, a mounting frame 3 detachably mounted on the side of the frame 1, and a feeding mechanism 5 arranged on the frame 1, the mounting frame 3 is provided with a clamping mechanism 4 arranged opposite to the positioning fixture 2, and the positioning fixture 2 is provided with a material taking mechanism 6. In this embodiment, the frame 1 includes a workbench 101, a working motor 102, a slide 103, a screw rod 2 and a nut (not shown in the figure) threadedly connected to the screw rod 2, and the slide 103 is arranged along the workbench 101. The positioning fixture 2 is arranged in the length direction, and includes an installation box 201, a movable plate 202 arranged on the lower end surface of the installation box 201, and a slider 203 screwed to the lower end surface of the movable plate 202. The slider 203 is slidably arranged in the slideway 103. After the working motor 102 is started, the screw rod 2 is driven to rotate. Through the connection between the screw rod 2 and the nut, the rotating screw rod 2 will drive the positioning fixture 2 to reciprocate along the slideway 103. The positioning fixture 2 also includes a chuck 204 and a pulley 205. The chuck 204 is used to clamp the pipe, and the pulley 205 is used to drive the chuck 204 to rotate.

[0026] In this embodiment, the number of feeding mechanisms 5 is no less than two groups, and the feeding mechanisms 5 are screwed to the front end surface or the rear end surface of the workbench 101. The feeding mechanism 5 includes a lifting component and a placement table installed at the lifting end of the lifting component. The placement table moves with the up and down movement of the lifting component. The placement table is used to place pipes, and the pipes are moved to a position relative to the chuck 204 through the lifting component. Generally, the size of the pipe is relatively long, so at least two groups of feeding mechanisms 5 are required to move the pipes. The feeding mechanism 5 also includes a rotating component 67, and the lifting component is installed on the rotating component 67. When loading, the rotating component 67 drives the lifting component to rotate until the placement table is located on the workbench 101, and the chuck 204 can clamp the pipe. After loading, the rotating component 67 drives the lifting component to rotate until the placement table is away from the workbench 101 to avoid interference with the placement table when the slide 103 of the positioning fixture 2 moves. The rotating component 67 and the lifting component are both existing technologies, and their structures are no longer repeated.

[0027] It should be noted that the two ends of the pipe are clamped by the chuck 204 and the clamping mechanism 4 respectively. By conveying the pipe by the positioning fixture 2 and clamping the pipe by the clamping mechanism 4, the pipe of a specified size can be conveyed to the cutting part of the pipe for cutting. The clamping mechanism 4 is a prior art and its structure will not be repeated.

[0028] The material picking mechanism 6 includes a mounting platform 61, a rotating component 67 rotatably connected to the mounting platform 61, a driving component arranged on the rotating component 67, a storage component 68 and a material picking component 66. The material picking component 66 includes a screw rod 663 and an airbag 666 arranged on the top of the screw rod 663. The driving component is used to drive the material picking component 66 to move to move the airbag 666. The material picking component 66 also includes an air pump 6610. The air pump 6610 is used to inflate or exhaust the airbag 666. The airbag 666 is used to hold the tail pipe. The material picking mechanism 6 is used to place the tail pipe in the positioning fixture 2 into the storage component 68.

[0029] Furthermore, the driving assembly includes a driving member 62 and a driving member 64. The displacement end of the driving member 62 is screwed to a receiving box 63. The driving member 62 is used to drive the receiving box 63 to move up and down in the vertical direction. The driving member 62 can optionally use a ball screw. The motor drives the ball screw to rotate, thereby driving its moving end (nut) to move along the screw, and then controlling the receiving box 63 to move in the vertical direction, wherein the ball screw needs to be set vertically.

[0030] Furthermore, the rotating assembly 67 includes a rotating motor (not shown in the figure) and a rotating shaft, the rotating shaft is detachably connected to the output end of the rotating motor, and a driving member 62 is vertically installed on the upper end surface of the rotating shaft, wherein the rotating motor is arranged in the mounting platform 61, the output end of the rotating motor is vertically arranged upward, and the driving member 62 is arranged on the upper end surface of the rotating shaft. After the rotating motor is started, the rotating shaft can be controlled to rotate, thereby controlling the driving member 62 to rotate. It should be noted that the rotating shaft of the pulley 205 needs to pass through the mounting platform 61. When opening a space for placing the rotating motor in the mounting platform 61, it should be noted that the space for placing the rotating motor and the space for the rotating shaft to pass through cannot be penetrated to prevent interference between the rotating motor and the rotating shaft.

[0031] Further, the second driving member 64 is arranged horizontally, the second driving member 64 is arranged on the receiving box 63, a connecting member 65 is arranged on the moving end of the second driving member 64, the second driving member 64 is used to drive the connecting member 65 to reciprocate in a straight line direction, and the material taking component 66 is arranged on the connecting member 65, wherein the second driving member 64 can select an electric push rod, the power part of the electric push rod is arranged in the receiving box 63, and its moving part (rod body for reciprocating movement) passes through the side wall of the receiving box 63 and extends to the receiving box 63. In addition, correspondingly, a through hole is opened on the side wall of the receiving box 63 for its moving part to pass through. Through the electric push rod, the position of the connecting member 65 can be changed in the horizontal direction. The connecting member 65 is used to connect the driving member 2 64 and the material picking component 66. It is also necessary to ensure that the airbag 1 666 of the material picking component 66 after connection is opposite to the chuck 204. The connecting member 65 can be an L-shaped rod. The horizontal part of the L-shaped rod, the moving part of the driving member 2 64 and the slide 103 are parallel to each other and are all horizontally arranged.

[0032] Furthermore, the material picking assembly 66 also includes a mounting plate 662 and a rotating motor 661 arranged on the side wall of the mounting plate 662, a screw rod 663 passes through the mounting plate 662, and one end of the screw rod 663 is detachably connected to the output end of the rotating motor 661, a moving seat 664 is threadedly connected to the screw rod 663, and the rotating motor 661 is used to drive the moving seat 664 to move along the length direction of the screw rod 663, and accordingly, two opposite through holes are opened on both sides of the mounting plate 662, and bearings 667 are arranged at the two through holes, and the screw rod 663 passes through the two bearings 667 and is pin-connected or key-connected to the two bearings 667.

[0033] Furthermore, a telescopic rod 669 is also provided on the mounting plate 662, and both ends of the telescopic rod 669 are detachably connected to the mounting plate 662 and the movable seat 664 respectively. In this embodiment, there are two telescopic rods 669, and the two telescopic rods 669 are respectively connected to the upper and lower ends of the movable seat 664, and the two are parallel, which can make the movable seat 664 more stable when moving.

[0034] Furthermore, airbag 2 665 is provided on the movable seat 664, and the air inlet end of airbag 2 665 is connected with the air outlet end of air pump 6610. Airbag 2 665 is used to carry the tail pipe. Air pump 6610 is provided on the storage box 63. Air pump 6610 has at least two air outlet ends, which are respectively connected with airbag 1 666 and airbag 2 665. Generally, air pipes can be used to connect airbag 1 666 and airbag 2 665 with air pump 6610. Airbag 1 666 can be connected with screw 1 663 through connecting rod 668.

[0035] In this embodiment, airbag 2 665 is arranged on the front end outer surface of the movable seat 664 and is perpendicular to airbag 1 666. When carrying special-shaped pipes, airbag 2 665 can assist airbag 1 666 in carrying the pipes, and can increase the contact area between the inner wall of the pipe and the airbag, so that the force area of ​​the pipe is increased when it is carried. In particular, the cross-section of the inner wall of the special-shaped pipe is also special-shaped. When airbag 1 666 carries the pipe, airbag 1 666 can only contact a smaller part of the inner wall of the pipe, which makes it easy for airbag 1 666 to fall off when carrying the pipe.

[0036] Furthermore, the feeding device for the pipe cutting machine also includes a controller 7 , and the material taking mechanism 6 , the working motor 102 and the feeding mechanism 5 are all control-connected to the controller 7 .

[0037] In this embodiment, the controller 7 controls the opening and closing of the driving member 1 62 and the driving member 2 64, so as to move the material taking component 66 to the detection position. The detection position refers to the position corresponding to the industrial camera 6611 and the chuck 204. The shape of the pipe cross section is obtained by the industrial camera 6611 to determine whether it is a special-shaped pipe and whether the airbag 2 665 is needed to assist the airbag 1 666 in carrying the pipe. If necessary, the rotating motor 661 is started to move the airbag 2 665 to a position close to the airbag 1 666, and then the airbag 1 666 and the airbag 2 665 are moved by the driving member 2 64. When it reaches the inside of the tail pipe, air is supplied to airbag one 666 and airbag two 665 through air pump 6610 until the two are in contact with the inner wall of the tube, the chuck 204 is released, and the tail pipe held by airbag one 666 and airbag two 665 is taken out from the chuck 204 through driving member two 64, and the held tail pipe is moved to the top of the storage member 68 through the rotating assembly 67, and the gas in airbag one 666 and airbag two 665 is extracted, and then airbag one 666 and airbag two 665 are retracted through driving member two 64, so that the two fall off the tail pipe, and the tail pipe loses support and falls into the storage member 68, completing the automatic recovery of the tail pipe.
