[0024] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0025] Please refer to Figure 1 and Figure 2 A eutectic table 1 clamping structure includes a frame and a eutectic table 1, a push rod 2, a driving assembly 3 and an elastic member 4 arranged on the frame. A limiting groove 11 is provided on one surface of the eutectic table 1. The push rod 2 can slide relative to the eutectic table 1 to approach or move away from the limiting groove 11. The elastic member 4 is connected to the push rod 2 to drive the push rod 2 to move in a direction close to the limiting groove 11. The driving assembly 3 is used to drive the push rod 2 to move in a direction away from the limiting groove 11.

[0026] From the above description, it can be seen that the beneficial effect of the utility model is that the elastic member 4 of the clamping structure of the eutectic table 1 is used to drive the ejector 2 to press the TO tube holder against the limiting groove 11 of the eutectic table 1 to achieve positioning, and the driving assembly 3 is used to make the ejector 2 release the TO tube holder. The clamping structure of the eutectic table 1 has fewer components and a simple movement process, which is conducive to improving production efficiency.

[0027] Furthermore, the driving assembly 3 includes a rotating driving member 31 and a cam 32 which are connected to each other, and the cam 32 can slidably contact the end of the push rod 2 away from the eutectic table 1 .

[0028] It can be seen from the above description that the driving assembly 3 has a simple structure and is easy to manufacture.

[0029] Furthermore, a roller 21 is provided at one end of the push rod 2 away from the eutectic table 1 .

[0030] It can be seen from the above description that the roller 21 can reduce the friction between the end of the push rod 2 and the cam 32, so that the process of the cam 32 driving the push rod 2 to slide is smoother.

[0031] Furthermore, the rotary driving member 31 is a motor.

[0032] As can be seen from the above description, the rotary drive member 31 is easy to obtain and use.

[0033] Furthermore, a detection sensor 5 is disposed on the frame, a blocking piece 6 is disposed on the cam 32 corresponding to the detection sensor 5 , and the detection sensor 5 is electrically connected to the rotation driving member 31 .

[0034] It can be known from the above description that the detection sensor 5 and the blocking piece 6 cooperate to determine the angle of the cam 32 , thereby controlling the opening and closing of the rotating driving member 31 .

[0035] Furthermore, the blocking piece 6 is connected to the cam 32 via bolts or buckles.

[0036] It can be seen from the above description that the rotation stroke of the cam 32 can be changed by changing the shape of the baffle 6 or the relative angle between the baffle 6 and the cam 32 .

[0037] Furthermore, two ends of the elastic member 4 are detachably connected to the frame and the top rod 2 respectively.

[0038] It can be seen from the above description that the squeezing force of the ejector rod 2 on the TO tube socket can be changed by replacing the elastic member 4 of different models and sizes.

[0039] Furthermore, there are multiple elastic members 4 , and the multiple elastic members 4 are evenly distributed around the circumference of the push rod 2 .

[0040] It can be seen from the above description that the uniform distribution of the plurality of elastic members 4 around the circumference of the push rod 2 can prevent the push rod 2 from tilting to one side.

[0041] Furthermore, the elastic member 4 is a spring, a spring sheet or a spring washer.

[0042] It can be seen from the above description that the type of the elastic member 4 can be selected according to actual use requirements or production conditions.

[0043] Furthermore, an elastic pad is provided at one end of the push rod 2 close to the eutectic table 1 .

[0044] It can be seen from the above description that the elastic pad can prevent the ejector rod 2 from crushing the TO tube socket.

[0045] Please refer to Figure 1 and Figure 2 , Embodiment 1 of the utility model is: a eutectic table 1 clamping structure, comprising a frame and a eutectic table 1, a push rod 2, a driving assembly 3 and an elastic member 4 arranged on the frame, a limiting groove 11 is provided on one surface of the eutectic table 1, the push rod 2 can slide relative to the eutectic table 1 to approach or move away from the limiting groove 11, the elastic member 4 is connected to the push rod 2 to drive the push rod 2 to move in the direction close to the limiting groove 11, and the driving assembly 3 is used to drive the push rod 2 to move in the direction away from the limiting groove 11. Specifically, the push rod 2 slides along its own length direction. The frame is provided with a sliding groove or an assembly hole, and the push rod 2 slides with the sliding groove or the assembly hole. The limiting groove 11 is adapted to the shape of a part of the TO tube seat, and the end of the push rod 2 close to the eutectic table 1 is adapted to the shape of a part of the TO tube seat. In this embodiment, the elastic member 4 is preferably a spring. In other embodiments, the elastic member 4 can be set as a spring sheet or a spring washer.

[0046] Preferably, both ends of the elastic member 4 are detachably connected to the frame and the top rod 2. In a certain embodiment, both ends of the elastic member 4 are provided with hooks, and the elastic member 4 is detachably connected to the frame and the top rod 2 through the hooks.

[0047] The driving assembly 3 includes a rotating driving member 31 and a cam 32 which are connected to each other, and the cam 32 can slide against the end of the ejector rod 2 away from the eutectic table 1. In this embodiment, the rotating driving member 31 is preferably a motor.

[0048] In order to reduce the friction between the push rod 2 and the cam 32 , a roller 21 is provided at one end of the push rod 2 away from the eutectic table 1 .

[0049] A detection sensor 5 is provided on the frame, and a baffle 6 is provided on the cam 32 corresponding to the detection sensor 5, and the detection sensor 5 is electrically connected to the rotating drive member 31. Specifically, the detection sensor 5 is preferably a contact sensor. The baffle 6 is fan-shaped, and the axial direction of the baffle 6 is colinear with the rotational axis of the cam 32. When the cam 32 rotates to a predetermined angle under the drive of the rotating drive member 31, the baffle 6 triggers the detection sensor 5. At this time, the push rod 2 is in an extreme position away from the limit groove 11, and the detection sensor 5 sends an electrical signal to the rotating drive member 31 so that it no longer applies torque to the cam 32, and the push rod 2 and the cam 32 are reset under the elastic force of the spring.

[0050] Preferably, the baffle 6 is connected to the cam 32 by bolts or buckles. By changing the shape of the baffle 6 or the relative angle between the baffle 6 and the cam 32, the rotation stroke of the cam 32 can be changed, that is, the movement stroke of the ejector rod 2 can be changed.

[0051] Preferably, there are multiple elastic members 4, and the multiple elastic members 4 are evenly distributed around the circumference of the top rod 2. The multiple elastic members 4 are evenly distributed around the circumference of the top rod 2 to prevent the top rod 2 from tilting to one side and causing excessive wear on one side of the top rod 2. In some embodiments, it is also feasible to sleeve the elastic member 4 on the top rod 2.

[0052] An elastic pad is provided at one end of the push rod 2 close to the eutectic table 1. The elastic pad can be made of rubber or silicone. The elastic pad can prevent the push rod 2 from crushing the TO tube seat.

[0053] In summary, the elastic member of the eutectic table clamping structure provided by the utility model is used to drive the ejector rod to press the TO tube holder against the limiting groove of the eutectic table to achieve positioning, and the driving assembly is used to make the ejector rod release the TO tube holder. The eutectic table clamping structure has fewer components and a simple movement process, which is conducive to improving production efficiency.
