[0002] After the pipes are cut and segmented, they need to enter the round tube chamfering device for chamfering. The existing round tube chamfering devices are all provided with an inlet and an outlet. However, the current operation method is to manually load the materials one by one from the storage rack, which has low work efficiency and wastes manpower. With the improvement of the mechanization degree of the production line, this method can no longer meet the production needs. At the same time, before the pipes enter the round tube chamfering device, they need to be accurately positioned to the specified position to facilitate the pipes to enter the chamfering mechanism and be in place at one time. However, the current structure has the following problems: the inlet cannot be positioned, and during the transfer of the pipes, the magnet adsorption method is currently used, which will cause partial position deviations, affecting product quality and production efficiency.

[0005] The feeding mechanism includes a storage component, a feeding component and a positioning component which are connected in sequence. The storage component includes a feeding frame and a feeding guide rail arranged thereon.

[0006] The chamfering mechanism includes a fixed base, a pressure block, and a tool holder with a cutter disc. The cutter disc is connected to a motor. Two tool holders are arranged on both sides of the fixed base. The cutter disc is arranged on the inner side of the tool holder and can rotate. The pressure block is arranged directly above the fixed base and can move up and down. The pressure block is connected to cylinder IV, and the tool holder is connected to the fixed base through a screw slider mechanism.

[0007] The transfer mechanism includes a sliding track, a slide seat, and a manipulator. The sliding track is fixedly connected to the frame and is arranged on the upper part of the frame. It includes two parallel optical axes I. The optical axis I is arranged horizontally and fixed at both ends. A cylinder I is fixedly arranged at one end of the optical axis I.

[0010] The support trough is provided with a vertical retaining edge on one side close to the support plate, the retaining edge is in contact with the processed pipe fitting, and cooperates with the stripping plate to limit the displacement direction of the supported pipe fitting. When the pipe fitting is supported, the pipe fitting slides upward along the retaining edge. When the pipe fitting approaches or exceeds the upper end of the retaining edge, the pipe fitting automatically rolls into the support trough under the action of the inclined surface; further, the inclined surface at this location is an inclined plane or an arc surface;

[0011] The limit baffle plate I and the limit baffle plate II are arranged at the supporting slot, the two plates are arranged in parallel, the limit baffle plate I is connected to the pushing device, and the position of the limit baffle plate II is adjustable.

The telescopic end of cylinder III is connected to the clamping claws on both sides. Cylinder III drives the clamping claws to clamp. There are two optical axes I and two sliding seats to ensure the accuracy of the manipulator during horizontal displacement.

[0013] The clamping jaws include two claw bodies that can be matched and symmetrically arranged. The claw bodies include double parallel connecting rods and a clamping head. The upper ends of the double parallel connecting rods are hinged to the lower ends of the supporting arms, and the lower ends of the double parallel connecting rods are hinged to the upper ends of the clamping heads. The four hinge points form a parallelogram. The telescopic end of the cylinder III is hinged to the double parallel connecting rods on both sides through the connecting rod II at the same time. When the telescopic end of the cylinder III moves downward, pushing the double parallel connecting rods to open, the clamping jaws open. Conversely, when the cylinder III moves upward, the clamping jaws close.

[0015] The device also includes a sensor and a controller. The sensors include sensor I, sensor II, and sensor III. Sensor I is arranged on a seat frame or cylinder I to sense the position of the slide seat. Sensor II is arranged on the seat frame to sense the position of the guide shaft. Sensor III is arranged in a supporting trough to sense whether there are pipe fittings in the supporting trough. Sensor I, sensor II, and sensor III are respectively connected to the controller. The controller is connected to the lifting devices of cylinder I, cylinder II, cylinder III, and cylinder IV. Sensor II and sensor III can be replaced by a delay switch.

[0016] Furthermore, the distance between side plate I and side plate II is slightly greater than the length of the processed pipe; further, a smooth long round rod is laid on the guide plate as a guide rail; the feed port of the storage assembly is a bell mouth, which is convenient for feeding; the optical axis II is arranged on both sides of the screw to limit the displacement direction of side plate I or side plate II, and further, the side plate I and side plate II are provided with shaft sleeves, which are slidably connected to the optical axis II.

[0018] At least one of the limit baffles I and II is a displacement party, and the limit baffle I or the limit baffle II is displaced closer to the other party. The two ends of the processed pipe are in contact and connected with the limit baffles I and II. The limit baffles I and II are used to limit the left and right positions of the pipe. After the pipe is clamped by the limit baffles I and II, the displacement party moves away from the pipe, and the position of the pipe is positioned, which is convenient for the pipe to enter the next process. During the working process, the limit baffle II is fixed and the pushing device is in motion. For example, under the driving action of the cylinder II, the limit baffle I approaches or moves away from the limit baffle II. The limit baffle II is connected to the frame through a screw, and the position of the limit baffle II and the frame can be adjusted by rotating the screw.

[0019] The working process of the present invention is as follows: a plurality of pipe fittings enter the upper part of the loading guide rail through the feeding port of the material storage component and are arranged in sequence. The front end of the pipe fitting B at the lowest position at the material storage component's discharge port is in contact with and connected to the baffle edge of the fixed component, and the pipe fitting C is in contact with and connected to the pipe fitting B. When there is no pipe fitting in the fixed component, the sensor sends a signal to the controller, the lifting device is activated, the supporting plate lifts the pipe fitting B above it, and the pipe fitting B slides up along the baffle edge. When its height reaches a certain height, it rolls into the supporting trough, and the supporting plate is reset. During the lifting process, the pipe fitting C is blocked by the supporting plate or the lifting device. During the resetting process of the supporting plate, when it is lower than the end edge of the discharge port, the pipe fitting C automatically rolls to the upper part of the supporting plate. After the pipe fitting B enters the supporting trough, it no longer moves forward and backward, and at least one of the limit baffle I and the limit baffle II moves close to the other, and the pipe fitting B is inferred to the specified position, and the positioning is completed.

[0020] Two groups of manipulators are used to transfer pipe fittings at two positions. Pipe fitting A at the center position is fixed on the fixed base of the round tube chamfering device for processing. The front and rear positions are the feed and position respectively. The specific working process is: manipulator A and manipulator B correspond to two adjacent positions of the three positions respectively. When the pipe fitting B to be processed is put into the feed support slot of the round tube chamfering device, manipulator A and manipulator B fall at the same time. After falling to a certain extent, the manipulators open and then clamp the pipe fittings at the corresponding positions. Manipulator A clamps the chamfered pipe fitting A in the seat of the round tube chamfering device, and the manipulator clamps the pipe fitting B. The manipulator rises, and the slide slides to the left end of the track. The two manipulators fall at the same time and release. Pipe fitting A is put into the discharge port, and pipe fitting B is put into the fixed seat of the round tube chamfering device. Then the manipulator rises, and the slide slides to the edge end to reset. After the round tube chamfering device completes processing of pipe fitting B, the transfer device repeats the action.

[0021] The beneficial effects of the present invention are as follows: the device is provided with a handwheel assembly, and the guide rail spacing can be adjusted according to the length of the pipe fitting; the guide rail is arranged obliquely, and the pipe fitting at the end of the guide rail is lifted into the positioning assembly through the loading assembly; the loading process of the entire round tube chamfering device is fully mechanized, and the pipe fitting is accurately positioned through the positioning assembly, and the workpiece can be accurately transferred through the transfer mechanism; the entire device is easy to operate and has precise positioning, which improves production efficiency, reduces labor intensity, and improves processing quality.

The pipe fitting A at the center position is fixed on the fixed base 18 of the round tube chamfering device for processing. The front and rear positions are the feed and position respectively. The specific working process is: manipulator A and manipulator B correspond to two adjacent positions of the three positions respectively. When the pipe fitting B to be processed is put into the feed support slot 12 of the round tube chamfering device, manipulator A and manipulator B fall at the same time. After falling to a certain extent, the manipulators open and then clamp the pipe fittings at the corresponding positions. Manipulator A clamps the chamfered pipe fitting A in the seat of the round tube chamfering device, and the manipulator clamps the pipe fitting B. The manipulator rises, and the slide 22 slides to the left end of the track. The two manipulators fall at the same time and release. Pipe fitting A is put into the discharge port, and pipe fitting B is put into the fixed seat of the round tube chamfering device. Then the manipulator rises, and the slide 22 slides to the edge end to reset. After the round tube chamfering device completes processing of pipe fitting B, the transfer device repeats the action.
