Description

Technical Field

[0001] This utility model belongs to the field of round tube processing, and in particular relates to a device for milling bevels at the ends of round tubes. Background Technology

[0002] In the field of modern industrial manufacturing, round tubes are widely used in industries such as petrochemicals, construction engineering, and machinery manufacturing. The milling of the ends of round tubes is a preliminary step for subsequent processes such as welding and assembly, and its processing accuracy and efficiency directly affect product quality and production efficiency.

[0003] With the continuous improvement of industrial automation, traditional milling equipment for the beveling end of round tubes has gradually revealed its limitations. Before milling the bevel of a round tube, it is necessary to adjust the angle of the tube so that the bevel is aligned with the milling head of the milling machine.

[0004] In the process of adjusting the angle of the round tube before beveling, traditional equipment generally lacks an integrated automatic angle calibration mechanism and relies solely on mechanical limiters or fixed tracks to achieve angle positioning, which is difficult to adapt to the beveling angle processing requirements of round tubes of different specifications. Utility Model Content

[0005] In view of the above problems, the purpose of this utility model is to provide a beveling device for the end milling of round tubes, which aims to solve the problems of inaccurate angle adjustment and unstable positioning of round tubes in existing beveling devices for the end milling of round tubes.

[0006] The present invention adopts the following technical solution:

[0007] The milling device for the end beveling of the round tube includes a machine base. The machine base is sequentially equipped with a feeding box, a clamping and feeding mechanism, and a milling machine. The feeding box has a feeding port at the bottom. The machine base is equipped with a liftable pusher seat located inside the feeding port. The top surface of the pusher seat is equipped with a row of support seats. Each support seat has a pair of support wheels rotatably mounted at both ends. The feeding box is equipped with an adjustment component facing the pusher seat. The adjustment component includes a pressing cylinder. The drive shaft of the pressing cylinder is equipped with a fixed seat. A synchronous shaft is rotatably mounted inside the fixed seat. Synchronous wheels are mounted at both ends of the synchronous shaft. Two pairs of left and right adjustment wheels are rotatably mounted below the fixed seat. The fixed seat is also equipped with a bidirectional motor. Each drive shaft of the bidirectional motor is equipped with a drive wheel. The drive wheel, synchronous wheel, and adjustment wheel on the same side are in close contact in sequence.

[0008] Furthermore, the side wall of the fixed base is provided with a mounting base, and the mounting base is provided with a sensor facing downwards.

[0009] Furthermore, the support base has a U-shaped groove, and a small portion of the support wheel protrudes from the U-shaped groove.

[0010] Furthermore, the machine base is equipped with a transverse linear motor, the moving end of the transverse linear motor is equipped with a top seat, the top seat is equipped with a moving cylinder, the drive shaft of the moving cylinder is equipped with a connecting seat, and the connecting seat is equipped with a pair of grippers.

[0011] The beneficial effects of this utility model are:

[0012] 1. This device can achieve precise adjustment of the angle of round tubes by adjusting the coordination of the bidirectional motor, drive wheel, synchronous wheel and adjustment wheel in the components. Compared with the traditional equipment that relies on mechanical limit or fixed track, it can better adapt to the beveling angle processing requirements of round tubes of different specifications, and effectively improve the consistency of beveling angle and processing accuracy.

[0013] 2. The U-shaped groove and support wheel design on the support base, combined with real-time detection by sensors, can effectively limit the movement and offset of the round tube during feeding and angle adjustment, providing a stable positioning effect. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this utility model patent clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0021] To illustrate the technical solution described in this utility model, specific embodiments are described below.

[0022] For ease of explanation, only the parts relevant to the embodiments of this utility model are shown.

[0023] Combination Figure 2-3 as well as Figure 6 As shown, the milling device for the end beveling of the round tube includes a machine base 1. The machine base 1 is provided with a feeding box 2, a clamping and feeding mechanism, and a milling machine 3 in sequence. The feeding box 2 has a feeding port at the bottom. The machine base 1 is provided with a liftable push seat 4 located in the feeding port. The top surface of the push seat 4 is provided with a row of support seats 5. Each support seat 5 has a pair of support wheels 6 rotatably mounted at both ends. The upper part of the feeding box 2 facing the push seat 4 is provided with an adjustment component. The adjustment component includes a pressing cylinder 7. The drive shaft of the pressing cylinder 7 is provided with a fixed seat 8. The fixed seat 8 is provided with a synchronous shaft 9 rotatably mounted. Both ends of the synchronous shaft 9 are provided with synchronous wheels 10. The fixed seat 8 is provided with two pairs of left and right adjustment wheels 11 rotatably mounted below it. The fixed seat 8 is also provided with a bidirectional motor 12. The drive shaft of the bidirectional motor 12 is provided with a drive wheel 13. The drive wheel 13, synchronous wheel 10, and adjustment wheel 11 on the same side are in close contact in sequence.

[0024] In this embodiment, the bottom surface of the loading box is inclined, and a loading port is opened below the bottom surface of the loading box. A push cylinder 22 is provided on the machine base, which drives the push seat to move up and down. Before milling the bevel of a round tube using this device, the round tube to be processed is first placed in the loading box as required, with the push seat at its lowest position. Driven by the push cylinder, the push seat rises, and the support seat and support wheels on it lift the round tube from bottom to top to its highest position, placing the round tube in an adjustment state. Then, the adjustment assembly adjusts the position of the round tube so that the bevel of the round tube is aligned with the milling head of the milling machine. After the round tube is adjusted, the clamping and feeding mechanism clamps the round tube and sends it to the milling machine for processing.

[0025] When adjusting the position of the circular tube using the adjusting assembly, the downward-pressing cylinder first drives the fixed base to descend until the adjusting wheel contacts the surface of the circular tube, and the circular tube is positioned between the pair of adjusting wheels. Then, the bidirectional motor starts, driving the synchronous wheel and adjusting wheel to rotate via the drive wheel. The adjusting wheel generates friction with the surface of the circular tube, thereby adjusting the angle of the circular tube.

[0026] This device can achieve precise adjustment of the angle of a round tube by adjusting the coordination of the bidirectional motor, drive wheel, synchronous wheel and adjustment wheel in the assembly. Compared with traditional equipment that relies on mechanical limit or fixed track, it can better adapt to the beveling angle processing requirements of round tubes of different specifications, and effectively improve the consistency of beveling angle and processing accuracy.

[0027] like Figure 1The circular tube a has a milled bevel a1 at one end and a groove a2 formed on its side wall. As a specific structure, the side wall of the fixed base 8 is provided with a mounting base 14, and a sensor 15 is positioned downwards on the mounting base 14. When adjusting the position of the circular tube using the adjustment assembly, the circular tube rotates slowly. The sensor detects the position and state of the circular tube in real time. When the sensor detects the groove, it feeds the data back to the control system, and the bidirectional motor immediately stops rotating. At this point, the milled bevel of the circular tube is aligned with the milling head of the milling machine.

[0028] In this structure, such as Figure 5 The support base 5 has a U-shaped groove 16, and a small portion of the support wheel 6 protrudes from the U-shaped groove. The design of the U-shaped groove can effectively restrict the lateral movement of the round tube, while the exposed support wheel can contact the round tube, providing stable support while reducing friction.

[0029] In this device, a horizontal linear motor 17 is provided on the machine base, a top seat 18 is provided on the moving end of the horizontal linear motor, a moving cylinder 19 is provided on the top seat, a connecting seat 20 is provided on the drive shaft of the moving cylinder 19, and a pair of grippers 21 are provided on the connecting seat.

[0030] After the tube angle is adjusted, the gripper clamps the tube, the downward cylinder drives the fixed seat to move upward, the adjusting wheel moves away from the tube, and the pusher moves down to its lowest position. The moving cylinder retracts a short distance, and then the horizontal linear motor drives the top seat to move laterally, sending the tube to the milling machine for end milling and beveling.

[0031] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
