The second ends of both connecting rods are hinged to the connecting seat, and the telescopic column is installed on the connecting seat.

[0011] Preferably, as one possible implementation, the locking assembly further includes a second elastic element, the telescopic column is slidably engaged with the connecting seat, and the second elastic element is connected between the telescopic column and the connecting seat for driving the telescopic column to extend;

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In use, the material can be placed in the material placement area first. Then, switch the locking component to the unlocked state to allow the connecting rod to move freely. At this time, push the second end of the connecting rod towards the material placement area, so that the clamping member hinged to the first end of the connecting rod moves along the first guide structure towards the material placement area. The material will be pushed by the clamping member towards the limiting member. Under the blocking and limiting of the limiting member, the material will be gradually compressed. After the material is compressed, switch the locking component to the locked state to lock the clamping mechanism. Thus, after the external force is removed, the clamping mechanism can remain in the current state to maintain the compression and positioning effect on the material, which can prevent the connecting rod from loosening due to vibration or other reasons on the production line. When it is necessary to disassemble the material, switch the locking component to the unlocked state so that the connecting rod can move freely. This allows the second end of the connecting rod to move away from the material placement area, causing the clamping member hinged to the second end of the connecting rod to move along the first guide structure away from the material placement area, thus removing the clamping force on the material. Then, switch the locking component to the locked state to prevent the clamping mechanism from clamping the material again, so that the material can be disassembled smoothly.

[0023] Therefore, the clamping and locking device provided by this utility model has a better positioning effect, and the material is not easy to shift or even fall off. Attached Figure Description

[0036] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0037] The present invention will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings.

[0038] See Figures 1-3This embodiment provides a clamping and locking device, which includes a fixed base 100, a locking assembly 200, two sets of clamping mechanisms 300, and several limiting members. Each clamping mechanism 300 includes a connecting rod 310, a clamping member 320, and a first guide structure 330. The first guide structure 330 is fixed to the fixed base 100 and cooperates with the clamping member 320 to guide the clamping member 320 to move towards or away from the material placement area. The clamping member 320 is hinged to the first end of the connecting rod 310, and the second ends of the connecting rod 310 in the two sets of clamping mechanisms 300 are hinged. The clamping member 320 and several limiting members are arranged around the material placement area to clamp and position the material in the material placement area. The locking assembly 200 can switch between a locked state and an unlocked state. In the locked state, the connecting rod 310 can be locked; in the unlocked state, the connecting rod 310 can move freely.

[0039] In use, the material can be placed in the material placement area first. Then, switch the locking component 200 to the unlocked state so that the connecting rod 310 can move freely. At this time, push the second end of the connecting rod 310 towards the material placement area, so that the clamping member 320 hinged to the first end of the connecting rod 310 moves along the first guide structure 330 towards the material placement area. The material will be pushed by the clamping member 320 towards the limiting member. Under the blocking and limiting of the limiting member, the material will be gradually compressed. After the material is compressed, switch the locking component 200 to the locked state to lock the clamping mechanism 300. Thus, after the external force is removed, the clamping mechanism 300 can remain in the current state to maintain the compression and positioning effect on the material, and prevent the connecting rod 310 from loosening due to vibration or other reasons on the production line. When it is necessary to disassemble the material, the locking component 200 is switched to the unlocked state, so that the connecting rod 310 can move freely. This allows the second end of the connecting rod 310 to be pulled away from the material placement area, causing the clamping member 320 hinged to the second end of the connecting rod 310 to move away from the material placement area along the first guide structure 330, thus removing the clamping force on the material. Then, the locking component 200 is switched to the locked state to prevent the clamping mechanism 300 from clamping the material again, so that the material can be disassembled smoothly.

[0040] Therefore, the clamping and locking device provided in this embodiment has a better positioning effect, and the material is not easily displaced or even falls off.

[0041] In the specific structure of the clamping mechanism 300, a first elastic element 340 and a pressing element 350 may also be provided. The pressing element 350 is fixed to the fixed base 100. One end of the first elastic element 340 is connected to the pressing element 350, and the other end is connected to the clamping element 350. The elastic force applied by the first elastic element 340 to the clamping element 320 is directed towards the material placement area. On the one hand, when the material is clamped, the first elastic element 340 can always provide a force to the pressing element 350 to compress the material, which is beneficial to improving the clamping and positioning effect of the material. On the other hand, when the connecting rod 310 is pushed to move towards the material placement area, the first elastic element 340 can provide assistance to the pressing element 350 towards the material placement area, so that the pressing element 350 can move smoothly towards the material placement area under the drive of the connecting rod 310, and is less likely to jam. The first elastic element 340 may be a spring.

[0042] In the same clamping mechanism 300, the elastic force direction of the first elastic member 340 is preferably set to be consistent with the guide direction of the first guide structure 330, so as to give full play to the role of the first elastic member 340 in pushing the pressing member 350 to squeeze the material, and to minimize the friction between the pressing member 350 and the first guide structure 330.

[0043] In the specific structure of the locking assembly 200, a connecting seat 210, a telescopic column 220, and a blocking member 230 can be provided. The second ends of the connecting rods 310 in both sets of clamping mechanisms 300 are hinged to the connecting seat 210. The telescopic column 220 is installed on the connecting seat 210 and can extend or retract on the connecting seat 210. The blocking member 230 is fixed to the fixed seat 100 and is configured to block the telescopic column 220 in the extended state, while allowing the telescopic column 220 in the retracted state to pass through the blocking member 230. The blocking member 230 has a first blocking surface 231 and a second blocking surface 232. The first blocking surface 231 is set to face the material placement area, and the second blocking surface 232 is set to face away from the material placement area.

[0044] After the material is placed in the material placement area, the telescopic column 220 can be retracted first, so that the connecting seat 210 can move freely. Then, the connecting seat 210 is driven to move toward the material placement area. Under the action of the connecting rod 310, the pressing member 350 can move toward the material placement area along the first guide structure 330 to press the material in the material placement area. After that, the telescopic column 220 is driven to extend. The telescopic column 220 in the extended state will abut against the first blocking surface 231 of the blocking member 230. Since the first blocking surface 231 faces the material placement area, the connecting seat 210 cannot move away from the material placement area under the blocking of the blocking member 230, thereby locking the clamping mechanism 300. When it is necessary to disassemble the material, the telescopic column 220 can be retracted first. Then, the connecting seat 210 can be moved away from the material placement area. After it is in place, the telescopic column 220 can be extended. The extended telescopic column 220 is on the side facing the second blocking surface 232 of the blocking member 230. Therefore, once the connecting seat 210 moves towards the material placement area for some reason, the second blocking surface 232 will block the telescopic column 220 in the extended state, so that the connecting seat 210 cannot continue to move towards the material placement area, and the material can be disassembled smoothly.

[0045] The blocking member 230 has a blocking frame, and the connecting seat 210 and the telescopic column 220 in the retracted state can pass through the blocking frame. The two sides of the blocking frame can be used as the first blocking surface 231 and the second blocking surface 232, respectively.

[0046] In the specific structure of the locking assembly 200, a second elastic element 240 may also be provided. The telescopic post 220 is slidably engaged with the connecting seat 210, and the second elastic element 240 is connected between the telescopic post 220 and the connecting seat 210. The second elastic element 240 can drive the telescopic post 220 to extend. Thus, when the telescopic post 220 extends, the locking assembly 200 can remain locked under the action of the second elastic element 340 without the need for additional driving force. The second elastic element 240 may be a spring.

[0047] In the specific structure of the locking component 200, a button 250 may also be provided, which is slidably engaged with the connecting seat 210 and is configured to protrude from the connecting seat 210. A first inclined surface 221 is provided on the telescopic column 220, which is configured to tilt in the direction of extension toward the side opposite to the button 250. Thus, pressing the button 250 will drive the telescopic column 220 to retract, which facilitates structural layout and operation. Specifically, the button 250 can be pressed manually; or it can be pressed using a cylinder or other power mechanism.

[0048] Preferably, a second inclined surface 222 can be provided at the protruding end of the telescopic column 220. When the clamping mechanism 300 clamps the material, the second inclined surface 222 at the protruding end can abut against the first blocking surface 231. In this way, the telescopic column 220 can retract automatically by simply pulling the connecting seat 210 towards the side opposite to the material placement area, improving the ease of operation. Specifically, the connecting seat 210 can be moved manually; alternatively, a robot or other mechanical structure can be used to pull the connecting seat 210. In this case, a hole can be pre-drilled in the connecting seat 210 so that the robot can be inserted into the pre-drilled hole to achieve the connection between the robot and the connecting seat 210.

[0049] Furthermore, the first blocking surface 231 can be set as an inclined surface, and the first blocking surface 231 can be set to be inclined in the direction away from the second blocking surface 232 along the telescopic column 220. Similarly, the telescopic column 220 can be retracted by simply pulling the connecting seat 210 towards the side away from the material placement area.

[0050] Preferably, the first blocking surface 231 and the second inclined surface 222 of the telescopic column 220 are arranged parallel to each other, which can increase the contact area when the two come into contact and reduce local stress.

[0051] A second guide structure 500 can be fixed on the fixed base 100. The second guide structure 500 is matched with the connecting base 210 to guide the connecting base 210 to move towards or away from the material placement area. This can improve the displacement accuracy and smoothness of the connecting base 210 and make it easy to operate.

[0052] The aforementioned locking assembly 200 may further include a handle 260, which engages with the second guide structure 500 to guide the movement of the handle 260. The handle 260 is positioned between the two connecting rods 310, specifically on the side of the connecting rods 310 facing the material placement area, allowing the handle 260 to abut against each of the two connecting rods 310. Thus, when material needs to be removed, manually pulling the handle 260 releases the clamping mechanism 300, enabling rapid unlocking. Preferably, a bearing 261 can be fitted over the handle 260, allowing the handle 260 to abut against the two connecting rods 310 via the bearing 261, improving operational smoothness.

[0053] The aforementioned limiting components include two sets of first limiting components 400. The limiting surfaces of each first limiting component 400 in the same set are set to be coplanar, and the limiting surfaces of the two sets of first limiting components 400 are set to be perpendicular to each other, i.e., the limiting surface of one set of first limiting components 400 is perpendicular to the limiting surface of the other set of first limiting components 400. The limiting surfaces of the two clamping components 320 are respectively set to be parallel to the limiting surfaces of the two sets of first limiting components 400, i.e., the limiting surface of one clamping component 320 is parallel to the limiting surfaces of one of the clamping components 320. The limiting surfaces of the first limiting member 400 are parallel, and the limiting surface of the other clamping member 320 is parallel to the limiting surface of the other first limiting member 400. The guides of the two first guide structures 330 are respectively set to be perpendicular to the limiting surfaces of the corresponding clamping members 320. The material placement area is located in the area enclosed by the two first limiting members 400 and the two clamping members 320. Driving the two clamping members 320 to move toward the material placement area can make the clamping members 320 cooperate with the limiting members to clamp the material.

[0054] Specifically, the guide angle between the second guide structure 500 and the first guide structure 330 can be set to 45°.

[0055] Both the first guide structure 330 and the second guide structure 500 mentioned above can be slide rails.

[0056] Two sets of second limiting members 600 can also be set among the several limiting members. The limiting surfaces of the two sets of second limiting members 600 are parallel to and opposite to the limiting surfaces of the two sets of first limiting members 600, and the two sets of first limiting members 600 and the two sets of second limiting members 600 form a material placement area. In this way, the material can be placed closer to the preset locking position.

[0057] Furthermore, a transport ear 700 can be fixed on the fixed base 100, so that the transport mechanism can grasp the transport ear 700 for transport.

[0058] In summary, this utility model embodiment discloses a clamping and locking device that overcomes many technical defects of traditional clamping mechanisms, such as poor positioning effect. The clamping and locking device provided by this utility model embodiment, by setting a clamping mechanism 300 and its locking component 200, enables the clamping mechanism 300 to maintain a good clamping and positioning effect after clamping the material, making it less likely for the material to shift or even fall off.
