[0030] Embodiment 1

[0031] This embodiment records a swing machine that can achieve continuous swinging without converting the motor rotation direction and can meet the swinging requirements during the cutting of various sizes of workpieces on the market.

[0032] As Figure 1 shown, the swing machine includes a swing base 1, a first support seat 2, an inner frame 3, a swing beam 4, a swing motor 5, a reducer 6, a swing transmission shaft 7, a second support seat 8, a crank 9, a linear slide rail 10, etc.

[0033] The inner frame 3 is of a frame structure. On both sides of the middle of the bottom of the inner frame 3, first support seats 2 are symmetrically installed. The first support seats 2 are placed on the swing base 1, and the centers of the first support seats 2 are connected to the swing base 1 through hinge shafts. The first support seats 2 can swing relative to the swing base 1 around the central hinge shaft, and thus the inner frame 3 can swing relative to the swing base 1. The swing base 1 is the support seat of the swing system, and the two symmetrically arranged swing bases 1 can ensure the stability of the swing motion of the swing machine.

[0034] The swing beam 4 is a beam for transmitting swing power, which consists of a fixed part and an extended part. The fixed part is installed on the top of one side of the inner frame 3 through a support frame, and the extended part extends to the front end of the inner frame 3. One or two linear slide rails 10 are fixed on the inner side of the extended part of the swing beam 4.

[0035] On the outer side of the front end of the inner frame 3, the swing motor 5 and the second support seat 8 are respectively installed on the fixed frame. The swing motor 5 is the swing power source, and a precision servo motor can be used. The output shaft of the swing motor 5 is connected to the speed reducer 6. The output shaft of the speed reducer 6 is connected to one end of the crank 9 through the swing transmission shaft 7. The other end of the crank 9 is rotatably connected to the slider on the linear slide rail 10, that is, the crank 9 can rotate relative to the slider. The crank 9 in this embodiment includes, but is not limited to, a long strip structure with arc ends at both ends. When the crank 9 rotates, the slider slides reciprocally along the linear slide rail 10. The second support seat 8 is sleeved on the swing transmission shaft 7 to support the swing transmission shaft 7 and reduce swing vibration.

[0036] The equipment that needs to perform the swing action is installed on the inner frame 4.3. In this embodiment, a wire cutting system is taken as an example for illustration. When the swing machine works, the swing motor 5 drives the crank 9 to rotate through the speed reducer 6 and the swing transmission shaft 7, drives the slider to move along the linear slide rail 10, and at the same time drives the first support seat 2 to swing relative to the swing base 1, so that the slider slides reciprocally along the linear slide rail 10. The linear slide rail 10 drives the entire inner frame 3 to swing back and forth through the swing beam 4, and then drives the wire cutting system to swing. During the cutting process, the wire cutting system increases the cutting amplitude and cutting force through the swing action, which is beneficial to improving the cutting efficiency.

[0037] Embodiment Two

[0038] This embodiment describes a swing machine, which is different from Embodiment One in that the structure of the swing machine is different, such as Figure 2 and Figure 3 As shown, the swing machine includes a swing beam 4, a swing motor 5, a speed reducer 6, a swing transmission shaft 7, a crank 9, a linear slide rail 10, a swing fixed base 11, a swing shaft end plate 12, a swing hinge seat 13, a swing lower cross beam 14, a swing hinge bearing 15, a swing hinge shaft 16, a swing column 17, a swing middle cross beam 18, a swing guide friction plate 19, a crank rotating shaft seat 20, and a coupling 21.

[0039] Two swing fixed bases 11 are arranged in parallel at intervals to support the swing machine. A vertical plate is provided at the center above the swing fixed base 11. The swing hinge seat 13 is a U-shaped structure with an opening facing downwards. The swing hinge seat 13 is buckled on the vertical plate, and the centers of the two are connected by a swing hinge shaft 16. Both ends of the swing hinge shaft 16 are respectively installed on the central side of the swing hinge seat 13 through swing shaft end plates 12. A swing hinge bearing 15 is sleeved on the swing hinge shaft 16. Thus, the swing fixed base 11, the swing shaft end plate 12, the swing hinge seat 13, the swing hinge bearing 15 and the swing hinge shaft 16 form a hinge structure, enabling the swing hinge seat 13 to swing relative to the center of the swing fixed base 11, and the swing hinge bearing 15 can reduce the friction when the swing hinge seat 13 swings relative to the swing fixed base 11.

[0040] The swing hinge seat 13, the swing lower cross beam 14, the swing columns 17, the swing middle cross beam 18 and the swing beam 4 form a swing frame. Two swing columns 17 are symmetrically installed on the swing hinge seat 13. At the lower part of the swing columns 17, both ends of the swing lower cross beam 14 are respectively fixed on the side walls of the swing columns 17. Multiple swing middle cross beams 18 are installed at intervals on the upper part of the swing columns 17. The fixed part of the swing beam 4 is installed on the tops of the two swing columns 17, and the extension part of the swing beam 4 extends to the front end of the swing columns 17.

[0041] In the middle of the extension parts of the two swing beams 4, a swing motor 5 is installed on a fixed frame. The output shaft of the swing motor 5 is connected to a speed reducer 6. The output end of the speed reducer 6 is connected to the center of a swing transmission shaft 7. Both ends of the swing transmission shaft 7 are respectively connected to a crank 9 through couplings 21. And crank rotation shaft seats 20 are symmetrically arranged on both sides of the speed reducer 6. The crank rotation shaft seats 20 are installed on the fixed frame. The swing transmission shaft 7 passes through the crank rotation shaft seats 20. The crank rotation shaft seats 20 provide rotational support for the swing transmission shaft 7 and reduce the vibration of the swing transmission shaft 7 during swinging. The crank 9 is connected to the inner side of the end of the extension part of the swing beam 4 through a slider on a linear slide rail 10. The crank 9, the slider and the linear slide rail 10 form a crank-slider structure.

[0042] When the swing motor 5 drives the crank 9 to rotate through the swing transmission shaft 7, the slider reciprocates along the linear slide rail 10. The crank 9 converts the received rotational power into linear power to drive the swing beam 4 to generate a linear motion, and the swing beam 4 drives the swing frame to swing back and forth.

[0043] Swing guide friction plates 19 can be respectively installed at both outer ends of the two swing beams 4. The swing guide friction plates 19 are in contact with the guide limit plates installed on the inner side of the fixed frame. When the swing machine swings, the swing guide friction plates 19 cooperate with the guide limit plates to achieve the lateral guide and limit function during the movement of the swing machine, ensuring swinging along the predetermined trajectory.

[0044] The rocking machine of this embodiment has a non-closed structure, which is beneficial for the loading and unloading of large and even extra-large workpieces.

[0045] Embodiment Three

[0046] This embodiment describes a rocking machine. The difference from the above two embodiments is that there is no linear slide rail 10 on the rocking beam 4 of the rocking machine. As Figure 4 shown, the extension part of the rocking beam 4 has a chute 22 along the axial direction. The slider 23 is placed in the chute 22, and the center of the inner end of the slider 23 is rotatably connected to one end of the crank 9. The other end of the crank 9 is connected to the rocking transmission shaft 7. When the rocking motor 5 drives the crank 9 to rotate through the rocking transmission shaft 7, the slider 23 reciprocates in the chute 22, converting the rotational motion into a linear motion. In this embodiment, to ensure the stable movement of the slider 23 along the chute 22, limit plates are provided at both ends of the slider 23. The diameter of the limit plates is larger than the width of the chute 22 to prevent the slider 23 from deviating from the chute 22 during movement.

[0047] In addition, to ensure the strength of the extension part of the rocking beam 4, the extension part integrates a reinforcing rib below the chute 22, and there is at least one weight-reducing hole 24 on the reinforcing rib, which can not only ensure the strength of the extension part but also avoid increasing the weight of the rocking beam 4.

[0048] Although the principle of the present invention has been described in detail above in conjunction with the preferred embodiments of the present invention, those skilled in the art should understand that the above embodiments are only explanations of the illustrative implementation manners of the present invention and do not limit the scope of the present invention. The details in the embodiments do not constitute a limitation on the scope of the present invention. Without departing from the spirit and scope of the present invention, any obvious changes such as equivalent transformations and simple replacements based on the technical solution of the present invention fall within the protection scope of the present invention.
