[0043] Specifically, there is only one first drive motor 2, which is arranged on the base 1. There are two first motion components, both of which extend in the left-right direction, and are installed on the front and rear sides of the base 1. Each first motion component includes a first bidirectional lead screw 3 extending in the left-right direction, and the first drive motor 2 is connected to one of the first bidirectional lead screws 3. The first transmission component is installed on the base 1, and the first transmission component extends in the front-rear direction.

[0045] Specifically, Figure 4As shown, in this embodiment, each first bidirectional lead screw 3 has a first rod segment 4 and a second rod segment 5, and the first rod segments 4 of the two first bidirectional lead screws 3 are located on the same side (left side), and the second rod segments 5 of the two first bidirectional lead screws 3 are located on the same side (right side).

[0046] Two support plates 10 are installed between the two first bidirectional lead screws 3, that is, one of the support plates 10 is installed on the first rod section 4 of the two first bidirectional lead screws 3, and the other support plate 10 is installed on the second rod section 5 of the two first bidirectional lead screws 3. The first drive motor 2 drives one of the first bidirectional lead screws 3 to rotate, driving the two support plates 10 to approach or move away from each other. There is only one second drive motor 11, and the second drive motor 11 is arranged on one of the support plates 10. Both support plates 10 extend in the front-to-back direction. There are two second motion components, and the two second motion components are respectively installed on the corresponding support plates 10, and the second motion components extend in the front-to-back direction.

[0047] The second transmission assembly is mounted on the base 1 and extends in the front-rear direction. The second transmission assembly is respectively connected to the two second bidirectional lead screws 21 so that the two second bidirectional lead screws 21 rotate simultaneously.

[0048] Specifically, the second transmission assembly includes a second transmission rod, two connecting members 14, two third bevel gears 13 and two fourth bevel gears 12. The second transmission rod extends in the front-back direction, and includes an outer rod 15 and an inner rod 16.

The two connecting members 14 are respectively mounted on the corresponding support plates 10, and the other ends of the outer rod 15 and the inner rod 16 are respectively rotatably mounted on the corresponding connecting members 14, that is, the other end of the outer rod 15 is mounted on the corresponding connecting member 14 through two tapered roller bearings, and the other end of the inner rod 16 is also mounted on the corresponding connecting member 14 through two tapered roller bearings. The two third bevel gears 13 are coaxially mounted on the outer rod 15 and the inner rod 16. The two fourth bevel gears 12 are coaxially mounted on the corresponding second bidirectional lead screws 21 , respectively, and the fourth bevel gears 12 are meshed with the corresponding third bevel gears 13 .

[0049] Specifically, Figure 4 As shown, each second motion assembly includes a second bidirectional lead screw 21, and the second bidirectional lead screw 21 has the same structure as the first bidirectional lead screw 3, and the second drive motor 11 is connected to one of the second bidirectional lead screws 21 by transmission. Each second bidirectional lead screw 21 has a third rod segment 22 and a fourth rod segment 23, and the third rod segments 22 of the two second bidirectional lead screws 21 are located on the same side (front side), and the fourth rod segments 23 of the two second bidirectional lead screws 21 are located on the same side (rear side). The thread directions on the third rod segment 22 and the fourth rod segment 23 of the same second bidirectional lead screw 21 are opposite, and the thread directions of the third rod segments 22 of the two second bidirectional lead screws 21 are the same, and the thread directions of the fourth rod segments 23 of the two second bidirectional lead screws 21 are the same. And one of the fourth bevel gears 12 is located on the front side of the corresponding third bevel gear 13, and the other fourth bevel gear 12 is located on the rear side of the corresponding third bevel gear 13.

[0050] There are four limit assemblies 18, namely, two limit assemblies 18 are provided on the third rod segment 22 of the two second bidirectional lead screws 21, and two limit assemblies 18 are also provided on the fourth rod segment 23 of the two second bidirectional lead screws 21, so that the second drive motor 11 drives the second bidirectional lead screw 21 to rotate, driving the two limit assemblies 18 on the same second bidirectional lead screw 21 to approach or move away from each other.

[0051] By setting a first transmission assembly between the two first motion assemblies, the two first bidirectional lead screws 3 can rotate synchronously, so only one first drive motor 2 is used to drive the two first bidirectional lead screws 3 to rotate synchronously, reducing the number of first drive motors 2 installed without affecting the use effect; then, a second transmission assembly is set between the two second motion assemblies, so that the two second bidirectional lead screws 21 can rotate synchronously, so only one second drive motor 11 is used to drive the two second bidirectional lead screws 21 to rotate synchronously, reducing the number of second drive motors 11 installed without affecting the use effect.

[0052] The structures of the first bidirectional lead screw 3 and the second bidirectional lead screw 21 in this embodiment can also refer to a bidirectional lead screw disclosed in the patent application document with publication number CN116838765A.

[0053] In order to support the outer rod 15 and prevent the outer rod 15 from being distorted, the second transmission assembly further includes a second support seat 17 . The second support seat 17 is fixedly mounted on the base 1 , and the outer rod 15 is slidably mounted on the second support seat 17 .

[0054] In order for the outer rod 15 to slide and rotate more smoothly on the second support seat 17 , a linear bearing 20 is provided on the second support seat 17 , and the linear bearing 20 is sleeved on the outer rod 15 .

[0055] In order to prevent the support plate 10 from being too long and the support plate 10 from bending and deforming due to the weight of the second moving component, a guide member 19 can be used to bear the weight of the support plate 10. Two guide members 19 are provided on the base 1. The two guide members 19 are respectively located under the corresponding support plates 10, and the support plate 10 is slidably installed on the guide members 19.

[0056] The working process of this utility model is as follows:

[0057] The first drive motor 2 drives one of the first bidirectional lead screws 3 to rotate, and the rotation of the first bidirectional lead screw 3 will be transmitted to the other first bidirectional lead screw 3 through the first transmission assembly, causing it to rotate, which will drive the two limit assemblies 18 on the same side of the two second bidirectional lead screws 21 to approach or move away from each other, wherein the two limit assemblies 18 are not on the same second bidirectional lead screw 21, but on the same side. The rotation directions of the two first bidirectional lead screws 3 are the same.

[0058] The second drive motor 11 drives one of the second bidirectional lead screws 21 to rotate, and the rotation of the second bidirectional lead screw 21 will be transmitted to the other second bidirectional lead screw 21 through the second transmission assembly, causing it to rotate, which will drive the two limit assemblies 18 on the same second bidirectional lead screw 21 to approach or move away from each other. The rotation directions of the two first bidirectional lead screws 3 are the same.

[0059] The positions of the four limit assemblies 18 are adjusted by driving the first drive motor 2 and the second drive motor 11 .

[0060] Example 2

[0061] In Example 1, the thread directions on the first rod segment 4 and the second rod segment 5 of the same first bidirectional screw 3 are opposite, the thread directions of the first rod segments 4 of the two first bidirectional screws 3 are the same, and the thread directions of the second rod segments 5 of the two first bidirectional screws 3 are the same.

[0062] like Figure 3 As shown, in this embodiment, the thread directions on the first rod segment 4 and the second rod segment 5 of the same first bidirectional screw 3 are also opposite, but in this embodiment, the thread directions of the first rod segments 4 of the two first bidirectional screws 3 are opposite, and at the same time, the thread directions of the second rod segments 5 of the two first bidirectional screws 3 are opposite, that is, the thread directions of the first rod segment 4 of one first bidirectional screw 3 and the second rod segment 5 of the other first bidirectional screw 3 are the same, and the thread directions of the second rod segment 5 of the first first bidirectional screw 3 and the first rod segment 4 of the second first bidirectional screw 3 are the same.

[0063] At the same time, the two second bevel gears 6 are located on the same side (left side or right side) of the first bevel gear 7. In this way, the two ends of the support plate 10 can move in the same direction.

[0064] Example 3

[0065] In Example 1, the thread directions on the third rod segment 22 and the fourth rod segment 23 of the same second bidirectional screw 21 are opposite, the thread directions of the third rod segments 22 of the two second bidirectional screws 21 are the same, and the thread directions of the fourth rod segments 23 of the two second bidirectional screws 21 are the same.

[0066] like Figure 3 As shown, in this embodiment, the thread directions on the third rod segment 22 and the fourth rod segment 23 of the same second bidirectional screw 21 are also opposite, but in this embodiment, the thread directions of the third rod segments 22 of the two second bidirectional screws 21 are opposite, and at the same time, the thread directions of the fourth rod segments 23 of the two second bidirectional screws 21 are opposite, that is, the thread directions of the third rod segment 22 of one second bidirectional screw 21 and the fourth rod segment 23 of the other second bidirectional screw 21 are the same, and the thread directions of the fourth rod segment 23 of the first second bidirectional screw 21 and the third rod segment 22 of the second bidirectional screw 21 are the same.

[0067] Meanwhile, the two fourth bevel gears 12 are located on the same side (front side or rear side) of the third bevel gear 13 .

[0068] Example 4

[0069] The difference between this embodiment and embodiment 1 is that the first transmission assembly in this embodiment is a worm gear structure, that is, the first transmission assembly includes two first support seats 9, a first transmission rod 8, two first worms and two first worm wheels, and a first worm is provided on the first bidirectional lead screw 3 that is transmission-connected to the first drive motor 2, and a first worm wheel is coaxially mounted on one end of the first transmission rod 8, and the first worm and the first worm wheel are meshed here. A first worm wheel is provided on the other first bidirectional lead screw 3, and a first worm is coaxially mounted on the other end of the first transmission rod 8, and the first worm wheel and the first worm are meshed here. The above structure can realize the synchronous rotation of the two first bidirectional lead screws 3.

[0070] The structure of the second transmission assembly is consistent with that of the first transmission assembly. However, the second transmission rod in the second transmission assembly still includes an outer rod 15 and an inner rod 16, and one end of the outer rod 15 is splined to one end of the inner rod 16, that is, the outer rod 15 and the inner rod 16 can slide relative to each other, and the outer rod 15 and the inner rod 16 can also rotate simultaneously. The above structure can realize the synchronous rotation of the two second bidirectional lead screws 21.

[0071] Example 5

[0072] The difference between this embodiment and embodiment 1 is that the first transmission assembly in this embodiment is a belt drive or a sprocket chain drive. At this time, pulleys are coaxially mounted on the two first bidirectional lead screws, and belts are wound around the two pulleys, so that the two first bidirectional lead screws rotate synchronously. The structures of the sprocket chain drive and the belt drive are similar, and will not be repeated in this embodiment.
