[0042] The present invention proposes an elastic clamping tray 100, such as Figures 1 to 6As shown, it includes: a shell 1, a driving mechanism 2, and a clamping mechanism 40. The driving mechanism 2 includes an elastic member 30, a first lever 21, a connecting rod assembly 3, and a torsion spring 20. The first end of the connecting rod assembly 3 is rotatably mounted on the shell 1, the first lever 21 is rotatably connected to the first end of the connecting rod assembly 3, and the second end of the connecting rod assembly 3 is rotatably connected to the clamping mechanism 40; the first end of the elastic member 30 is mounted on the shell 1, and the second end of the elastic member 30 is mounted on the first lever 21; the torsion spring 20 is sleeved on the first end of the connecting rod assembly 3, the first end of the torsion spring 20 is fixed to the first lever 21, and the second end of the torsion spring 20 is fixed to the connecting rod assembly 3; the first lever 21 has a first moving position and a second moving position. In the first moving position, the clamping mechanism 40 is in an open state; in the second moving position, the clamping mechanism 40 is in a closed state; wherein, in the first moving position or the second moving position, the elastic member 30 is in a taut state.

[0043] Specifically, refer to Figure 2 and Figure 3 As shown, Figure 2 is a schematic diagram of the clamping mechanism 40 when the first lever 21 is in the first moving position, Figure 3 The figure is a schematic diagram of the clamping mechanism 40 of the first lever 21 at the second moving position. When the elastic clamping tray 100 is used, the first lever 21 is driven to rotate counterclockwise to move the first lever 21 from the first moving position to the second moving position. The first lever 21 is rotationally connected to the connecting rod assembly 3, but the torsion spring 20 is sleeved on the outside of the first pin 33 of the connecting rod assembly 3. The first lever 21 drives the connecting rod assembly 3 to move through the elasticity of the torsion spring 20, and drives the first end of the connecting rod assembly 3 to rotate counterclockwise. The connecting rod assembly 3 drives the clamping mechanism 40 to move, so that the clamping position 7 is in a closed state. During the process of the first lever 21 moving to the second moving position, the elastic member 30 is stretched, and the clamping mechanism 40 clamps the workpiece at the clamping position 7, and the elastic member 30 is in a taut state.

[0044] If workpieces of different sizes are encountered, after the inner wall of the clamping mechanism 40 abuts against the workpiece, the clamping mechanism 40 stops moving, the tension of the elastic member 30 is greater than the elastic force of the torsion spring 20, and when the first lever 21 is in the second moving position, the elastic member 30 will pull the first lever 21, the torsion spring 20 is deformed by the pressure, and the first lever 21 will squeeze the workpiece through the torsion spring 20, so that when the elastic clamping tray 100 clamps a larger workpiece, the clamping force of the clamping mechanism 40 is greater. When it is necessary to pick up the workpiece on the clamping position 7, the first lever 21 is driven to rotate clockwise, so that the first lever 21 moves from the second moving position to the first moving position, the first end of the connecting rod assembly 3 moves clockwise, and the clamping position 7 of the clamping mechanism 40 is driven to open, and the workpiece can be picked up from the clamping position 7.

[0045] When operating the elastic clamping tray 100, it is only necessary to move the first lever 21 in a clockwise or counterclockwise direction to switch the first lever 21 between the first moving position and the second moving position. The elastic member 30 is in a taut state, that is, the elastic force of the elastic member 30 itself can limit the clamping mechanism 40 in the closed or expanded state. In the absence of external force, the clamping mechanism 40 is relatively stable in the closed or expanded state, thereby improving the stability of the workpiece at the clamping position 7 and facilitating the processing of the workpiece at the clamping position 7.

[0046] The clamping working principle of the elastic clamping tray 100 is as follows: the second end of the elastic member 30 is fixed to the first lever 21, and the first end thereof is fixed to the clamping mechanism 40. When the first lever 21 rotates, the second end of the elastic member 30 will move circumferentially around the first end thereof. The force of the elastic member 30 always acts on the first lever 21, but will generate a counterclockwise or clockwise force according to the position of the first lever 21. Therefore, when the first lever 21 is in the first moving position, the force generated by the elastic member 30 acts on the first lever 21, so that the first lever 21 has a counterclockwise force. The first lever 21 rotates counterclockwise to drive the connecting rod assembly 3 to be in a folded state. The connecting rod assembly 3 drives the clamping assembly 40 to make the clamping position 7 in an open state. At this time, the torsion spring 20 is in an initial state. The first lever 21 is in the second moving position, and the force generated by the elastic member 30 acts on the first lever 21, so that the first lever 21 has a clockwise force. The first lever 21 drives the connecting rod assembly 3 to move through the torsion spring 20, and drives the connecting rod assembly 3 to a vertical state. The connecting rod assembly 3 drives the clamping position 7 of the clamping mechanism 40 to close, thereby clamping the workpiece.

[0047] When the size of the workpiece is large, the connecting rod assembly 3 is slightly bent, the elastic member 30 is greatly deformed, and the torsion spring 20 is also compressed. The reaction force generated by the torsion spring 20 acts on the connecting rod assembly 3, and the force is transmitted to the clamping mechanism 40 through the connecting rod assembly 3, so that the clamping mechanism 40 is firmly clamped. Therefore, the larger the clamped object is, the greater the deformation of the torsion spring 20 is, and the clamping is more firmly when the first lever 21 moves from the first moving position to the second moving position. Since the elastic member 30 is always in a taut state, when the first lever 21 is in the first moving position, the elastic member 30 will drive the clamping position 7 of the clamping mechanism 40 to open. In the absence of external force, the elastic force of the elastic member 30 can always drive the clamping mechanism 40 to prevent the clamping position 7 from closing. When the first lever 21 is in the second moving position, the elastic member 30 will drive the clamping mechanism 40 to close. Similarly, the elastic force of the elastic member 30 always drives the clamping mechanism 40 to prevent the clamping force of the clamping mechanism 40 from being loosened.

[0048] In some embodiments, Figure 2 , Figure 5 , Figure 6As shown, the connecting rod assembly 3 includes a first transmission rod 31, a second transmission rod 32, a first pin shaft 33, a first rotating shaft 34, and a second rotating shaft 35. The first end of the first transmission rod 31 is rotatably connected to the first pin shaft 33, the first shift rod 21 is rotatably connected to the first pin shaft 33, the torsion spring 20 is sleeved on the outside of the first pin shaft 33, and the two ends of the torsion spring 20 are respectively fixed to the first shift rod 21 and the first transmission rod 31, and the first pin shaft 33 is rotatably arranged on the housing 1; the second end of the first transmission rod 31 is sleeved on the outside of the first rotating shaft 34, the first end of the second transmission rod 32 is sleeved on the outside of the first rotating shaft 34, the first transmission rod 31 is rotatably connected to the second transmission rod 32 through the first rotating shaft 34; the second rotating shaft 35 is rotatably installed on the clamping mechanism 40, the second end of the second transmission rod 32 is sleeved on the outside of the second rotating shaft 35, and is rotatably connected to the second rotating shaft 35.

[0049] Specifically, refer to Figure 2 and Figure 3 As shown, when the first lever 21 rotates counterclockwise around the first pin 33 on the housing 1, the first lever 21 drives the first transmission rod 31 to move through the torsion spring 20, and the first rotating shaft 34 between the first transmission rod 31 and the second transmission rod 32 rotates, and drives the first transmission rod 31 and the second transmission rod 32 to open, and the first transmission rod 31 drives the second transmission rod 32 to move toward the clamping mechanism 40, and pushes the clamping position 7 of the clamping mechanism 40 to close. At this time, the elastic member 30 is stretched and limits the clamping mechanism 40. In the absence of external force, the clamping position 7 of the clamping mechanism 40 is always in a closed state and can stably clamp the workpiece. When the first lever 21 rotates clockwise, the elastic member 30 is stretched again, and the first lever 21 drives the first transmission rod 31 and the second transmission rod 32 to approach each other, so that the clamping position 7 of the clamping mechanism 40 expands, which is convenient for picking up the workpiece.

[0050] In addition, if Figure 5 and Figure 6 As shown, the driving mechanism 2 has two second pins 36, one of which is mounted on the first lever 21, and the other second pin 36 is mounted on the housing 1. The first rotating rod 31 also has a second pin 36, so that the two ends of the torsion spring 20 are fixed to the first lever 21 and the second pin 36 on the first rotating rod 31 respectively. The elastic member 30 is a spring, and the two ends of the spring are fixed to the first lever 21 and the second pin 36 on the housing 1 respectively. The second pin 36 is used to raise the installation height of the spring so that when the first lever 21 moves, the spring will not be interfered by the connecting rod assembly 3. In addition, the second pin 36 is also used to fix the torsion spring 20 to the first lever 21 and the first rotating rod 31 respectively.

[0051] In some embodiments, Figure 2As shown, the driving mechanism 2 further comprises a first gear shaft 22, a second gear shaft 23, and a second lever 24. The first gear shaft 22 and the second gear shaft 23 are both rotatably mounted on the housing 1, and the first gear shaft 22 meshes with the second gear shaft 23. The second lever 24 is sleeved outside the first gear shaft 22, and the second gear shaft 23 is fixed to the first end of the connecting rod assembly 3. The second lever 24 is arranged along the radial direction of the first gear shaft 22, and the first lever 21 is arranged along the radial direction of the second gear shaft 23. Specifically, by rotatably mounting the first gear shaft 22 and the second gear shaft 23 on the housing 1, the second lever 24 is used to drive the first gear shaft 22 to rotate, and the first lever 21 is used to drive the second gear shaft 23 to rotate. When the first lever 21 rotates counterclockwise, the second gear shaft 23 drives the first gear shaft 22 to rotate, so that the second lever 24 rotates clockwise. When the second lever 24 rotates clockwise, the first gear shaft 22 drives the second gear shaft 23 to rotate, so that the first lever 21 rotates counterclockwise. Therefore, in the elastic clamping tray 100 , the first lever 21 or the second lever 24 can be used to drive the clamping mechanism 40 to open or close, thereby further improving the flexibility of the elastic clamping tray 100 .

[0052] In addition, if Figure 1 As shown, the housing 1 has a first opening 11, a second opening 12, a support frame 13, a support platform 14, and a third opening 15. The tops of the first gear shaft 22 and the second gear shaft 23 are rotatably mounted on the support frame 13, and the bottoms of the first gear shaft 22 and the second gear shaft 23 are rotatably mounted on the bottom of the housing 1. The support frame 13 is used to support the first gear shaft 22 and the second gear shaft 23. The first opening 11 and the second through hole 12 are opened on the outer wall of the housing 1. The first opening 11 is used for allowing the first lever 21 to be at least partially exposed relative to the housing 1, and the second opening 12 is used for allowing the second lever 24 to be at least partially exposed relative to the housing 1. The third opening 15 is opened on the top of the housing 1 for allowing the clamping mechanism 40 to be at least partially exposed. The support platform 14 is set on the clamping position 7 to support the workpiece on the clamping position 7.

[0053] In some embodiments, Figure 2 and Figure 3As shown, the clamping mechanism 40 includes a first clamping member 4, a second clamping member 5, and a transmission assembly 6. The first clamping member 4 and the second clamping member 5 are both movably arranged in the housing 1, and a clamping position 7 is formed between the first clamping member 4 and the second clamping member 5; the transmission assembly 6 is movably installed in the housing 1, the first clamping member 4 is transmitted and cooperated with the second clamping member 5 through the transmission assembly 6, and the first clamping member 4 or the second clamping member 5 is installed at the output end of the driving mechanism 2; there is a moving path between the first clamping member 4 and the second clamping member 5 that approaches or moves away from each other, the first lever 21 is in the first moving position, the first clamping member 4 and the second clamping member 5 are away from each other; the first lever 21 is in the second moving position, the first clamping member 4 and the second clamping member 5 are close to each other.

[0054] Specifically, when the connecting rod assembly 3 drives the first clamping member 4 to move, the first clamping member 4 is transmitted and cooperated with the second clamping member 5 through the transmission assembly 6, so that the first clamping member 4 and the second clamping member 5 have a moving path that approaches or moves away from each other; therefore, when the first clamping member 4 moves toward the second clamping member 5, the second clamping member 5 will also move toward the first clamping member 4, so that the first clamping member 4 and the second clamping member 5 move toward each other; when the first clamping member 4 moves away from the second clamping member 5, the second clamping member 5 will also move toward the first clamping member 4, so that the first clamping member 4 and the second clamping member 5 move away from each other, thereby reducing the moving clamping time of the clamping mechanism 40 and improving the clamping efficiency of the clamping mechanism 40.

[0055] In some embodiments, Figure 4 As shown, the transmission assembly 6 includes a first connecting rod 63, a second connecting rod 64, and a first transmission member 61. The first transmission member 61 includes a first transmission rack 611, a first transmission gear 612, and a second transmission rack 613. The first end of the first connecting rod 63 is mounted on the first clamping member 4, and the second end of the first connecting rod 63 is fixed to the first transmission rack 611; the first end of the second connecting rod 64 is mounted on the second clamping member 5, and the second end of the second connecting rod 64 is mounted on the second transmission rack 613; the first transmission rack 611 is transmitted and matched with the second transmission rack 613 through the first transmission gear 612. Specifically, when the connecting rod assembly 3 pushes the first transmission rack 611 to move, the first transmission rack 611 drives the first transmission gear 612 to rotate, and the first transmission gear 612 drives the second transmission rack 613 to move, so that the first transmission rack 611 and the second transmission rack 613 are closer to or farther away from each other, and the second transmission rack 613 will drive the second clamping member 5 to move when moving, further realizing the first clamping member 4 and the second clamping member 5 to approach or move away from each other, so that the clamping mechanism 40 has the function of clamping the workpiece.

[0056] Preferably, Figure 4As shown, the first transmission rack 611 and the second transmission rack 613 are both provided with a plurality of tooth grooves on one side facing the first transmission gear 612, and the tooth grooves of the first transmission rack 611 are arranged opposite to the tooth grooves of the second transmission rack 613, and the first transmission gear 612 is respectively meshed with the tooth grooves of the first transmission rack 611 and the second transmission rack 613. Specifically, the first transmission rack 611 and the second transmission rack 613 are both meshed with the first transmission gear 612, and when the first transmission rack 611 moves forward, the first transmission rack 611 drives the first transmission gear 612 to rotate clockwise, and the first transmission gear 612 will drive the second transmission rack 613 to move backward; similarly, when the first transmission rack 611 moves backward, the first transmission rack 611 drives the first transmission gear 612 to rotate counterclockwise, and the first transmission gear 612 will drive the second transmission rack 613 to move forward, further realizing the first clamping member 4 and the second clamping member 5 to move closer to or away from each other.

[0057] In order to improve the stability of the first transmission rack 611 and the second transmission rack 613 in the housing 1.

[0059] In this embodiment, the technical principle and effect of the second transmission member 62 to achieve the mutual approach or mutual distance between the first clamping member 4 and the second clamping member 5 have been described in the first transmission member 61, and will not be repeated here. The first clamping member 4 is supported by the first connecting rod 63, the second connecting rod 64 supports the second clamping member 5, and the first transmission member 61 and the second transmission member 62 are arranged on both sides of the first connecting rod 63 and the second connecting rod 64.

Specifically, when the first clamping member 4 and the second clamping member 5 are close to each other, the first clamping plate 41 and the second clamping plate 51 are surrounded, so that the inner walls of the first clamping plate 41 and the second clamping plate 51 are against the workpiece, thereby clamping or fixing the workpiece on the clamping position 7. When the connecting rod assembly 3 drives the first clamping member 4 to move, the first connecting seat 42 drives the first connecting rod 63 to move, and drives the second connecting seat 52 to move through the first transmission member 61 and the second transmission member 62, drives the second clamping plate 51 to move, and further realizes the movement of the second clamping member 5.

[0061] The present invention also provides an operating method of the elastic clamping tray 100, comprising the following steps:

[0062] The first lever 21 is driven to move clockwise or counterclockwise, and the first lever 21 drives the clamping mechanism 40 to move through the connecting rod assembly 3, so that the clamping mechanism 40 moves to a closed or open state;

[0063] During the process of the first lever 21 moving from the first moving position to the second moving position and / or during the process of the first lever 21 moving from the second moving position to the first moving position, the elastic member 30 is in a stretched state.

[0064] By driving the first lever 21 to rotate clockwise or counterclockwise, the clamping mechanism 40 can clamp the workpiece, and the operation method is simple. The elastic member 30 is in a tight state after the clamping mechanism 40 clamps the workpiece. When the size of the workpiece is larger than the preset size clamped at the clamping position 7, the elastic member 30 is also in a tight state.
