Description

Technical Field

[0001] The present invention relates to the field of laser cutting technology, and more specifically to a laser cutting processing device for agricultural machinery parts. Background Art

[0002] Laser cutting is very common in agricultural machinery parts, especially in situations where high precision, high efficiency and complex shape processing are required. For example, pipes are often used in agricultural machinery and equipment, such as structural components of irrigation systems and livestock equipment. Laser cutting machines can accurately cut and shape these pipes to meet various complex design requirements.

[0003] The existing laser cutting equipment dedicated to pipes includes a clamping mechanism, a rotating mechanism and a moving mechanism. When laser cutting the surface of the pipe, most of the time, the clamping mechanism is used to clamp the surface of the pipe multiple times. The rotating mechanism is arranged at the active end of the moving mechanism, and the end of the pipe is fixed to the rotating end of the rotating mechanism. The rotating end of the rotating mechanism rotates to drive the pipe to rotate relative to the clamping mechanism, and the moving end of the moving mechanism moves to drive the rotating mechanism to move the pipe relative to the clamping mechanism to assist laser cutting. However, agricultural machinery irrigation pipes are relatively long, and the horizontal length of the moving mechanism required for the laser cutting equipment suitable for agricultural machinery irrigation pipes is relatively long, resulting in the laser cutting equipment being too large in size. In addition, when installing the pipe, the end and surface of the pipe need to be fixed, which is time-consuming and labor-intensive, and has low applicability. In view of this, we propose a laser cutting processing equipment for agricultural machinery accessories. Summary of the invention

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention forms a clamping cavity by setting the gaps between four clamping wheel units to clamp the pipe fittings of agricultural machinery, and sets a transmission belt to make the two clamping wheel units form a linkage, and sets a rotating mechanism A to drive the two clamping wheel units to rotate to drive the displacement of the pipe fittings of agricultural machinery, thereby greatly reducing the volume. By setting the movable end of the control mechanism to be connected with the input end of the friction mechanism, when the friction mechanism is controlled to be frictionally connected with the fixed part, the output end of the rotating mechanism B drives the ring block A to rotate, and the ring block B does not rotate, so that the size of the clamping cavity formed by the gaps between the four clamping wheel units changes for loading and unloading the pipe fittings of agricultural machinery. When the friction mechanism is controlled to rub with the pipe block, when the output end of the rotating mechanism B drives the ring block A to rotate, the ring block B rotates synchronously, driving the rotation of the pipe fittings of agricultural machinery, and assisting the laser cutting of the pipe fittings of agricultural machinery, thereby improving the functionality and solving the technical problem of low applicability of laser cutting processing equipment for agricultural machinery fittings.

[0021] 2. The present invention further designs the clamping wheel unit and arranges the clamping wheel cross-section to be a trapezoidal structure, so that four clamping wheel units, that is, eight clamping wheels, constitute an octagonal column-shaped clamping cavity, so that the agricultural machinery pipe can be automatically positioned to the center of the clamping cavity by adjusting the size of the clamping cavity at any angle, so that the inclined parts of the eight clamping wheels contact the surface of the agricultural machinery pipe, thereby clamping and limiting the agricultural machinery pipe.

[0022] 3. The present invention designs the rotating mechanism A so that when the output shaft of the motor A is controlled to rotate by an external control mechanism, the connecting shaft A rotates, causing the gear A to drive the annular tooth groove to rotate, thereby causing the clamping wheel to rotate, and then one of the pulleys drives the other pulley to rotate through the transmission belt, causing the two clamping wheel units to rotate. The number of teeth of the gear A is designed to be smaller than the number of teeth of the annular tooth groove, thereby reducing the rotational resistance of the output shaft of the motor A, allowing the motor A to use a smaller volume with relatively low power, further reducing the volume of the device, and improving the relative variation range of the clamping cavity size, thereby further improving the applicability of the device.

[0023] 4. The present invention further designs the displacement guide groove, so that after the friction mechanism moves to squeeze and rub with the fixed part or the pipe block, the reaction force causes the second ring to have a displacement tendency, so that the hemispherical block has a reaction force on the displacement guide groove, and the gear ring C has a rotation tendency. By designing that both ends of the partial thread groove are connected and open with arc grooves, when the hemispherical block moves to the arc groove, the force applied by the hemispherical block to the arc groove cannot drive the gear ring C to rotate, thereby eliminating the force on the output shaft of the motor C in a static state, reducing the loss of the motor C, and improving the service life of the device.

[0024] 5. The present invention further designs the friction ring to ensure that when the rotation state of the clamping cavity size is changed to the rotating ring of the control clamping mechanism as a whole to drive the agricultural machinery pipe to rotate, the inclined parts of the eight clamping wheels can always be in contact with the surface of the agricultural machinery pipe, and the size of the clamping cavity will not be driven by the weight of the agricultural machinery pipe to drive the ring block B to rotate. When the friction mechanism moves, when one friction ring is not completely separated from the head end of the fixed ring block, the other friction ring needs to be squeezed and contacted with the pipe block, so that the fixed ring block, the friction mechanism and the ring block B form a relatively fixed structure. The friction resistance makes it difficult for the ring block B to rotate by itself. The outer ring part and the inner ring part are designed to be integrally connected at both ends by a V-shaped part, which improves the deformation ability of the friction ring. In the initial stage of movement of the friction mechanism, the angle of the V-shaped part is opened, so that the two friction rings are in friction contact with the pipe block and the fixed ring block respectively, providing rotation resistance for the ring block B.

The head end of the connecting shaft C78 is fixed with a gear C79, and the gear C79 is meshed and connected with the gear ring C71. The motor C70 is fixed at one side of the tail end of the mounting frame 2 relative to the position of the connecting shaft C78, ​​and the motor C70 is fixedly connected with the tail end of the connecting shaft C78. Through the above arrangement, the present invention makes the above arrangement so that when the output shaft of the motor C70 is controlled to rotate by the external control mechanism, the connecting shaft C78 and the gear ring C71 rotate, so that the gear ring C71 rotates and drives the displacement guide groove 73 to rotate, so that the hemispherical blocks 76 move in the displacement guide groove 73 and drive the second ring 74 to move.

[0064] In the embodiment of the present invention, the displacement guide groove 73 includes a partial thread groove 731, and both ends of the partial thread groove 731 are connected to form an arc groove 732. The present invention further designs the displacement guide groove 73, so that after the friction mechanism 5 moves to squeeze and rub with the fixed part 6 or the pipe block 32, the reaction force causes the second ring 74 to have a displacement tendency, so that the hemispherical block 76 has a reaction force on the displacement guide groove 73, so that the gear ring C71 has a rotation tendency, and by designing that both ends of the partial thread groove 731 are connected to form an arc groove 732, when the hemispherical block 76 moves to the arc groove 732, the force applied by the hemispherical block 76 to the arc groove 732 cannot drive the gear ring C71 to rotate, thereby eliminating the force on the output shaft of the motor C70 in a static state, reducing the loss of the motor C70, and improving the service life of the device.

[0065] In an embodiment of the present invention, the friction ring 54 includes an embedding portion 541, an inner ring portion 542 and an outer ring portion 543. The embedding portion 541 is embedded in the embedding groove 53, the inner ring portion 542 is fixed to the end of the embedding portion 541 away from the embedding groove 53, and the outer ring portion 543 is arranged at the end of the inner ring portion 542 away from the embedding portion 541. Both ends of the outer ring portion 543 and the inner ring portion 542 are integrally connected by a V-shaped portion 544, and the two V-shaped portions 544 are arranged in a symmetrical structure. The present invention further designs the friction ring 54. In order to ensure that when the rotation state of controlling the size of the clamping cavity is changed to the rotating ring of controlling the overall rotation of the clamping mechanism 3 to drive the agricultural machinery pipe to rotate, the inclined parts of the eight clamping wheels 3922 can always be in contact with the surface of the agricultural machinery pipe, and the size of the clamping cavity will not be driven by the weight of the agricultural machinery pipe to drive the ring block B37 to rotate. When the friction mechanism 5 moves, when one friction ring 54 is not completely separated from the head end of the fixed ring block 63, the other friction ring 54 needs to be squeezed and contacted with the pipe block 32, so that the fixed ring block 63, the friction mechanism 5 and the ring block B37 form a relatively fixed structure. The friction resistance makes it difficult for the ring block B37 to rotate by itself. The outer ring part 543 and the inner ring part 542 are designed to be integrally connected at both ends by the V-shaped part 544, which improves the deformation ability of the friction ring 54. In the initial stage of movement of the friction mechanism 5, the angle of the V-shaped part 544 is opened, so that the two friction rings 54 are in friction contact with the pipe block 32 and the fixed ring block 63 respectively, providing rotation resistance for the ring block B37.

[0066] In an embodiment of the present invention, the rotating mechanism B8 includes a gear ring B81, a connecting shaft B82 and a motor B84, the gear ring B81 is fixed at the head end of the ring block A34, the connecting shaft B82 is rotatably arranged on the other side of the fixed seat 61 relative to the position of the gear ring B81, the head end of the connecting shaft B82 passes through the rotating seat 31 and is fixed with a gear B83, the gear B83 is meshed and connected with the gear ring B81, the connecting shaft B82 is rotatably connected with the rotating seat 31, the motor B84 is fixed at the other side of the tail end of the mounting frame 2 relative to the position of the connecting shaft B82, and the output shaft of the motor B84 is fixedly connected to the tail end of the connecting shaft B82. The present invention, through the design of the rotating mechanism B8, controls the rotation of the output shaft of the motor B84 through an external control mechanism, so that the connecting shaft B82 and the gear B83 rotate, and the rotation of the gear ring B81 drives the ring block A34 to rotate.

[0067] Working principle: This embodiment provides a laser cutting and processing device for agricultural machinery parts. When in use, the agricultural machinery pipe is transferred to the clamping cavity formed by the gap between the four clamping wheel units 392;

[0068] When the output shaft of the motor C70 is controlled to rotate by the external control mechanism, the connecting shaft C78 and the gear ring C71 rotate, so that the gear ring C71 rotates and drives the displacement guide groove 73 to rotate, causing the hemispherical block 76 to move in the displacement guide groove 73 and drive the second ring 74 to move, causing the connecting ring 55 to drive the first ring 51 to move, and the first limit slider 52 slides relative to the first limit slide groove 372, causing the friction ring 54 to squeeze the fixed ring block 63, and the friction force makes the ring block B37 unable to rotate;

[0069] The present invention designs the rotating mechanism B8 so that the output shaft of the motor B84 can be controlled to rotate by an external control mechanism, so that the connecting shaft B82 and the gear B83 can rotate, so that the gear ring B81 can rotate to drive the ring block A34 to rotate, and the movable ring 3913 can move in the inclined guide groove 35, so that the movable slider 3914 can slide in the centripetal guide groove 38, so that the entire clamping assembly 39 can move, and the gap between the four clamping wheel units 392 can form a clamping cavity that becomes smaller to clamp the surface of the agricultural machinery pipe.

[0070] Control so that one friction ring 54 is completely separated from the head end of the fixed ring block 63, and the other friction ring 54 needs to be in extrusion contact with the pipe block 32;

[0071] At this time, the rotation of the output shaft of motor B84 is controlled by an external control mechanism, which can drive the entire clamping mechanism 3 to rotate, thereby causing the agricultural machinery pipe to rotate. When the output shaft of motor A42 is controlled by an external control mechanism to rotate, the connecting shaft A41 rotates, causing the gear A43 to drive the annular tooth groove 3924 to rotate, thereby causing the clamping wheel 3922 to rotate, and then one of the pulleys 3923 drives the other pulley 3923 to rotate through the transmission belt 393, causing the two clamping wheel units 392 to rotate and drive the agricultural machinery pipe to move.
