Therefore, the drawings and the description are considered to be exemplary in nature rather than restrictive.

[0026] The present utility model will be described in detail below with reference to the drawings and embodiments.

[0027] Embodiment 1

[0028] As Figures 1 to 6As shown in the figure, this embodiment provides a multi-track automatic swing device, including: a base 1; a swing table 2; a transmission mechanism 3; one end of the transmission mechanism 3 is movably arranged on the base 1, and the other end of the transmission mechanism 3 is connected to the swing table 2; an adjustment mechanism 4; one end of the adjustment mechanism 4 is arranged on the base 1, and the other end of the adjustment mechanism 4 is connected to the transmission mechanism 3; a driving mechanism 5; the driving mechanism 5 is arranged on the base 1, and the movable end of the driving mechanism 5 is connected to the transmission mechanism 3.

[0029] In this embodiment, the transmission mechanism 3 is movably arranged on the base 1, the swing table 2 is arranged at the upper end of the transmission mechanism 3, and under the action of the driving mechanism 5, the transmission mechanism 3 can drive the swing table 2 to automatically perform reciprocating swing motion;

[0030] The adjustment mechanism 4 is arranged on the base 1 and connected to the transmission mechanism 3. The adjustment mechanism 4 can adjust the transmission mechanism 3 and make it have a variety of different structural states. When the transmission mechanism 3 is in different structural states, the swing trajectory of the transmission mechanism 3 will also change correspondingly, so that the swing table has a variety of different swing modes, and the device is more flexible to use.

[0031] Further, the transmission mechanism 3 includes: a crank rocker 31, a guiding component 32 and a swinging component 33; one end of the crank rocker 31 is connected to the driving mechanism 5, and the other end of the crank rocker 31 is connected to the swinging component 33; one end of the guiding component 32 is movably arranged on the base 1, and the other end of the guiding component 32 is connected to the adjustment mechanism 4; one end of the swinging component 33 is movably arranged on the guiding component 32, and the other end of the swinging component 33 is connected to the swing table 2.

[0032] In this embodiment, the guiding component 32 is rotatably arranged on the base 1 and connected to the swinging component 33. The two ends of the crank rocker 31 are respectively connected to the swinging component 33 and the driving mechanism 5. When the driving mechanism 5 works, the swinging component 33 can be made to perform reciprocating swing motion along the guiding component 32 within a certain range through the crank rocker 31; the guiding component 32 is connected to the adjustment mechanism 4, and the internal structural state of the guiding component 32 can be adjusted through the adjustment mechanism 4. When the guiding component 32 is in different structural states, the movement trajectory of the swinging component 33 also changes accordingly, so as to generate different movement trajectories. The swing table 2 is arranged at the movable end of the swinging component 33. After the movement trajectory of the swinging component 33 changes, the movement trajectory of the swing table 2 can also change correspondingly, so as to achieve the multi-track swing effect of the device.

[0033] Further, the guiding component 32 includes: a lifting plate 321; a first transmission rod 322 and a second transmission rod 323 are respectively rotatably arranged at two ends of the lifting plate 321; the lifting plate 321 is movably arranged on the adjusting mechanism 4; the first transmission rod 322 is rotatably arranged on one side of the base 1; the second transmission rod 323 is rotatably arranged on the other side of the base 1; the swinging component 33 is respectively movably arranged on the first transmission rod 322 and the second transmission rod 323.

[0034] In this embodiment, the lifting plate 321 is sleeved on the adjusting mechanism 4, and the lifting plate 321 can move longitudinally along the adjusting mechanism 4; the first transmission rod 322 and the second transmission rod 323 are respectively rotatably arranged at two ends of the lifting plate 321, and the first transmission rod 322 and the second transmission rod 323 are respectively rotatably arranged on the left and right sides of the base 1, and the first transmission rod 322 and the second transmission rod 323 are arranged in a mirror-symmetrical manner (see Figure 1 and Figure 3 ), when the lifting plate 321 is at different height positions on the adjusting mechanism 4, the first transmission rod 322 and the second transmission rod 323 can have corresponding inclinations;

[0035] Both ends of the swinging component 33 are slidably arranged on the first transmission rod 322 and the second transmission rod 323. When the lifting plate 321 is at different height positions, under the action of different inclinations of the first transmission rod 322 and the second transmission rod 323, the swinging component 33 can generate corresponding different swinging trajectories, thereby driving the swing table 2 to swing along corresponding trajectories;

[0036] In addition, strip-shaped holes 7 are arranged at the ends of the first transmission rod 322 and the second transmission rod 323 (see Figure 6 ), when the lifting plate 321 is at different height positions, the first transmission rod 322 and the second transmission rod 323 rotate and the connection lengths with the lifting plate 321 change. Through the design of the strip-shaped holes 7, the change in the connection distance between the transmission rod and the lifting plate 321 can be satisfied.

[0037] Further, the swinging component 33 includes: a mounting plate 331; a first transmission shaft sleeve 332 and a second transmission shaft sleeve 333 are respectively rotatably arranged at two ends of the mounting plate 331; the mounting plate 331 is connected to the crank rocker 31; the first transmission shaft sleeve 332 is slidably arranged on the first transmission rod 322; the second transmission shaft sleeve 333 is slidably arranged on the second transmission rod 323; the swing table 2 is arranged on the mounting plate 331.

[0038] In this embodiment, one end of the first transmission shaft sleeve 332 is rotatably connected to the mounting plate 331, and the other end is slidably disposed on the first transmission rod 322; one end of the second transmission shaft sleeve 333 is rotatably connected to the mounting plate 331, and the other end is slidably disposed on the second transmission rod 323. The first transmission shaft sleeve 332 and the second transmission shaft sleeve 333 can jointly drive the mounting plate 331 to swing. When the lifting plate 321 is at different height positions, the mounting plate 331 has corresponding different swinging trajectories through the above connection relationship, thereby driving the swing table 2 to swing along corresponding trajectories.

[0039] Further, the adjusting mechanism 4 includes: a support plate 41; a plurality of limiting blocks 42 that are movably disposed on the support plate 41 and can position the lifting plate 321; the support plate 41 is disposed on the base 1; the lifting plate 321 is slidably disposed on the support plate 41.

[0040] In this embodiment, there are two limiting blocks 42. The two limiting blocks 42 divide the support plate 41 into three regions: an upper section, a middle section, and a lower section. The lifting plate 321 can be fixed in the above three regions respectively, so that the lifting plate 321 has three different height positions, thereby enabling the first transmission rod 322 and the second transmission rod 323 of the guiding assembly 32 to have three corresponding inclinations (respectively, the upward convex position, the horizontal position, or the downward convex position). The swinging trajectories of the mounting plate 331 corresponding to different positions are also different. Furthermore, the movement trajectory of the swing table on the transmission mechanism 3 can be changed through the adjusting mechanism 4.

[0041] Further, a receiving cavity is provided inside the support plate 41; a pull plate 43 that can control the moving position of the limiting block 42 is movably disposed in the receiving cavity.

[0042] In this embodiment, the pull plate 43 is disposed in the receiving cavity of the support plate 41. The pull plate 43 has a ramp structure (see Figure 4 ) corresponding to the position of the limiting block 42. When the pull plate 43 moves upward, the limiting block 42 can be moved inward, so that the limiting block 42 is separated from the lifting plate 321, facilitating the adjustment of the height position of the lifting plate 321; when the pull plate 43 moves downward and resets, the limiting block 42 can reset under the action of the spring and re-engage with the lifting plate 321, thereby achieving the positioning effect on the lifting plate 321.

[0043] Further, at least one guide rail 44 is provided on the outer side of the support plate 41; at least one slider corresponding to and slidably connected to the guide rail 44 is provided on the lifting plate 321.

[0044] In this embodiment, two guide rails 44 are provided on the outer side of the support plate 41, and two sliders are provided on the inner side of the lifting plate 321. The sliders can reciprocally slide on the guide rails 44, so that the lifting plate 321 can move longitudinally more smoothly under the matching effect between the guide rails 44 and the sliders, preventing jamming.

[0045] Further, the driving mechanism 5 includes: a bracket 51, a driving motor 52 and a transmission gear set 53; the bracket 51 is arranged on the base 1; the driving motor 52 is arranged on the bracket 51, and the output end of the driving motor 52 is in transmission connection with the transmission gear set 53; the transmission gear set 53 is arranged on the bracket 51, and the output end of the transmission gear set 53 is connected to the crank rocker 31.

[0046] In this embodiment, the bracket 51 is arranged on the base 1, the driving motor 52 and the transmission gear set 53 are both arranged on the bracket 51, the output end of the driving motor 52 is connected to the transmission gear set 53, and the driving motor 52 and the transmission gear set 53 can be in transmission connection by means of synchronous belt wheels. The output end of the transmission gear set 53 is connected to the crank rocker 31. When the driving motor 52 works, the torque can be transmitted to the crank rocker 31 through the transmission gear set 53, so that the crank rocker 31 drives the mounting plate 331 to swing within a certain range, thereby achieving the driving effect on the transmission mechanism 3 and enabling the transmission mechanism 3 to operate automatically.

[0047] Further, an output rotating shaft 6 is arranged on the transmission gear set 53; the output rotating shaft 6 is connected to the crank rocker 31.

[0048] In this embodiment, the output rotating shaft 6 is installed on the transmission gear set 53 and rotates synchronously with the gears of the transmission gear set 53. The output rotating shaft 6 is connected to the crank rocker 31, and the torque output by the transmission gear set 53 can be synchronously transmitted to the crank rocker 31, so that the crank rocker 31 drives the mounting plate 331 to swing within a certain range, thereby achieving the driving effect on the transmission mechanism 3.
