DETAILED DESCRIPTION

[0023] The technical solution of the present invention is further elaborated in detail below in conjunction with specific embodiments. The parts that are not described and disclosed in detail in the following embodiments of the present invention should be understood as existing technologies known or should be known to those skilled in the art, such as the specific structure of the swing arm 1, the installation of the rack 1001 and the connecting block, the structure of the buffer 4, etc.

[0024] Example

[0025] A mechanical arm for transporting cylindrical rollers, such as Figure 1As shown, it includes a base 5 and a swing rod 1. The base 5 is rotatably provided with a rotating shaft 2. A connecting block is fixedly connected to the upper surface of the base 5. The rotating shaft 2 is rotatably connected to the connecting block, and one end of the rotating shaft 2 extends out of the connecting block. The rotating shaft 2 is vertically fixedly connected to the end of the swing rod 1. The bottom end of the swing rod 1 is provided with a connecting hole with the same diameter as the rotating shaft 2. The rotating shaft 2 passes through the connecting hole and is key-connected to the swing rod 1, so that the rotating shaft 2 can drive the swing rod 1 to swing during the rotation of the rotating shaft 2. The end of the swing rod 1 away from the rotating shaft 2 is provided with a receiving tube 8 capable of accommodating a roller. The axis of the receiving tube 8 is parallel to the axial direction of the rotating shaft 2. The receiving tube 8 is a circular cylindrical structure with two ends open. In this embodiment, a connector 101 is fixed to the end of the swing rod 1 away from the rotating shaft 2. The connection method of the connector 101 and the swing rod 1 is bolt connection. The top of the connector 101 is an arc-shaped end face. The radius of curvature of the arc-shaped end face is the same as the radius of curvature of the outer wall of the receiving tube 8. When the receiving tube 8 is installed on the connector 101, part of the outer wall of the receiving tube 8 fits with the arc-shaped end face. The connection method between the two is bolt connection. The outer wall of the receiving tube 8 is provided with a processing hole 801 for processing equipment to process the roller. The processing hole 801 is a square hole. The roller is processed in the receiving tube 8, which simplifies the roller transportation process and improves the roller transportation efficiency and processing efficiency.

[0026] During the rotation of the rotating shaft 2, the accommodating cylinder 8 is driven to swing back and forth from the loading area to the processing area. The loading area is the position of the accommodating cylinder 8 when the roller enters the accommodating cylinder 8. Figure 1 As shown; the processing area is the position of the receiving tube 8 when the roller is processed, such as Figure 3 As shown, when the rotating shaft 2 rotates clockwise, it drives the accommodating cylinder 8 to deflect from the loading area to the processing area. When the rotating shaft 2 rotates counterclockwise, it drives the accommodating cylinder 8 to deflect from the processing area to the loading area. Two parallel slide rails 11 are arranged at the bottom of the base 5, and the length direction of the slide rails 11 is parallel to the axis of the rotating shaft 2. The slide rails 11 are fixedly connected to the processing equipment for processing the rollers. The connection method of the two is bolt connection. The base 5 can reciprocate along the slide rails 11 to drive the accommodating cylinder 8 to reciprocate from the loading area to the separation area. The separation area is the position of the accommodating cylinder 8 when the roller is separated from the accommodating cylinder 8. Figure 4 As shown; the base 5 moves in a direction parallel to the axis of the rotating shaft 2, and during the movement of the base 5, the accommodating tube 8 is separated from the roller inside it, completing a roller transfer process. The transfer process is simple and efficient, which improves the processing efficiency of the roller; at the same time, during the entire transfer process, the roller is located in the accommodating tube 8, and its surface is not subjected to pressure, reducing the wear on the roller surface.

[0027] The diameter of the accommodating cylinder 8 is 1-2mm larger than the diameter of the roller, which facilitates the roller to enter the accommodating cylinder 8 and, at the same time, prevents the roller from shaking violently in the accommodating cylinder 8 during transportation, causing the outer wall of the roller to collide with the accommodating cylinder 8; after the roller is transported to the processing area, the fixing component of the processing equipment fixes the roller. When the roller is processed, the roller rotates relative to the accommodating cylinder 8. At this time, the axis of the roller coincides with the axis of the accommodating cylinder 8, so that a gap is formed between the outer wall of the roller and the inner wall of the accommodating cylinder 8, avoiding friction between the outer wall of the roller and the inner wall of the accommodating cylinder 8 to cause wear on both, thereby improving the processing quality of the roller and the service life of the accommodating cylinder 8.

[0028] A stopper 802 is provided in the receiving tube 8 to limit the position of the roller inside the receiving tube 8, so as to ensure that the roller is completely located in the receiving tube 8 and prevent the roller from entering the receiving tube 8 too deeply, thereby affecting the fixation of the processing equipment. When the roller enters the receiving tube 8, it will hit the stopper 802 due to inertia. Therefore, the stopper 802 is made of nylon to prevent the end face of the roller from being damaged by the impact.

[0029] Two limit rods 6 are symmetrically arranged on the swing rod 1, and the limit rods 6 are fixedly connected to the swing rod 1. Two limit blocks 7 corresponding to the limit rods 6 are arranged on the base 5, and the limit blocks 7 are fixedly connected to the base 5. The connection method of the two is bolt connection. When the accommodating cylinder 8 rotates to the loading area or the processing area, the end of the limit rod 6 conflicts with the corresponding limit block 7. The cooperation of the limit block 7 and the limit rod 6 can limit the rotation angle of the accommodating cylinder 8 and position it, so that the accommodating cylinder 8 can be accurately located in the loading area and the processing area, ensuring that the roller can smoothly enter the accommodating cylinder 8 when the accommodating cylinder 8 is located in the loading area; at the same time, it is ensured that when the accommodating cylinder 8 is located in the processing area, the roller is fixed by the processing equipment and is coaxial with the accommodating cylinder 8.

[0030] When the accommodating cylinder 8 deflects to the loading area or the processing area, the limiting rod 6 will collide with the limiting block 7 due to inertia, causing damage to the limiting member 802 or the limiting block 7. Figure 1 As shown, two buffers 4 are arranged on the base 5, and the two buffers 4 are located on both sides of the manipulator. Specifically, the buffer 4 on the left is fixedly connected to the base 5 through the first fixed plate 401, and a reinforcing plate is fixedly connected between the first fixed plate 401 and the base 5; the buffer 4 on the right is fixedly connected to the base 5 through the second fixed plate 402. A buffer block 3 located between the two buffers 4 is fixedly connected to the rotating shaft 2. Specifically, a fixing hole with the same diameter as the rotating shaft 2 is opened at the bottom end of the buffer block 3, and the rotating shaft 2 passes through the fixing hole and is key-connected with the buffer block 3. When the accommodating cylinder 8 rotates to the loading area or the processing area, the buffer block 3 contacts the corresponding buffer 4 to avoid a violent collision between the limiter 802 and the limiter block 7.

[0031] like Figure 5As shown, a first driving assembly for driving the rotating shaft 2 to rotate is provided on the base 5, and the first driving assembly includes a rack 1001 slidably connected to the base 5 and a first driving cylinder 10 for driving the rack 1001 to reciprocate. A transmission gear 201 meshing with the rack 1001 is coaxially fixedly connected to the rotating shaft 2. The piston of the first driving cylinder 10 is fixedly connected to the rack 1001 and can drive the rack 1001 to reciprocate. The reciprocating movement of the rack 1001 drives the reciprocating rotation of the transmission tooth, thereby driving the reciprocating rotation of the rotating shaft 2.

[0032] The base 5 is connected to a second driving cylinder 12 for driving the base 5 to reciprocate. The piston of the second driving cylinder 12 is fixedly connected to the base 5 to drive the base 5 to reciprocate along the slide rail 11 .

[0033] The loading area is fixedly provided with a baffle plate 9, the extension direction of which is perpendicular to the axial direction of the rotating shaft 2, and the baffle plate 9 is fixed on a mounting frame, and the mounting frame is fixedly connected to the processing equipment. The baffle plate 9 is fixedly connected to the mounting frame through a third fixing plate, and the third fixing plate is an "L"-shaped plate structure, including a vertical portion fixedly connected to the mounting frame and a horizontal portion connected to the baffle plate 9, wherein the vertical portion and the mounting frame are connected by welding or bolting. In this embodiment, the connection between the two is bolted, and the vertical portion is provided with long strip holes distributed in the vertical direction, and the height of the baffle plate 9 can be adjusted according to the diameter of the roller; the horizontal portion is provided with an adjustment hole, and the adjustment hole extends in a direction parallel to the axial direction of the rotating shaft 2, and the baffle plate 9 can slide along the extension direction of the long strip hole and can be fixed, and the connection between the horizontal portion and the baffle plate 9 is bolted, that is, the distance between the baffle plate 9 and the mounting frame is adjusted according to the height of the roller, which improves the applicability of the utility model.

[0034] A separation groove 803 is provided on the outer wall of the accommodating tube 8. The separation groove 803 includes a first part and a second part which are connected to each other. The first part extends along the axial direction of the accommodating tube 8, and the second part extends along the circumference of the accommodating tube 8. When the accommodating tube 8 moves from the loading area to the separation area, the baffle plate 9 is located in the separation groove 803 and restricts the roller, so that the roller is separated from the accommodating tube 8. The first part and the second part are both long strip holes, and the ends of the two are connected to make the separation groove 803 "L" shaped. The end of the first part away from the second part extends to the edge of the accommodating tube 8, that is, the end of the first part away from the second part is an opening. When the accommodating tube 8 is in the first orientation, the baffle plate 9 passes through the connection between the first part and the second part; when the accommodating tube 8 moves from the loading area to the separation area, the baffle plate 9 slides relative to the first part to block the roller from moving with the accommodating tube 8. The width of the first part is greater than the width of the baffle plate 9, so as to avoid friction between the baffle plate 9 and the first part when the baffle plate 9 slides relative to each other, thereby causing wear on the edge of the baffle plate 9 and the inner wall of the first part. When the accommodating cylinder 8 rotates from the loading area to the processing area, the baffle plate 9 and the second part slide relative to each other until the baffle plate 9 is separated from the separation groove 803. The setting of the second part prevents the baffle plate 9 from colliding with the accommodating cylinder 8 during the rotation of the accommodating cylinder 8; the width of the second part is greater than the thickness of the baffle plate 9, which prevents friction between the baffle plate 9 and the second part when they slide relative to each other, thereby causing wear between the end face of the baffle plate 9 and the inner wall of the second part.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention.
