[0009] The telescopic rod has a mounting groove at one end, a fixing hole perpendicular to the mounting groove, and a stop flange formed circumferentially.

[0010] Two grippers, the main body of the grippers is in the shape of a "7", one end is connected to a pressure plate, and the other end is machined with a second pin hole. The first pin hole is located between the pressure plate and the second pin hole.

The telescopic rod's movement towards the support causes one end of the gripper to move synchronously, rotating the gripper around the first pin hole, thus separating the mating pressure blocks. Releasing the handle releases the compressed spring, pushing the telescopic rod back to its original position. The telescopic rod then moves one end of the gripper away from the support, causing the pressure blocks at the other end of the gripper to close again, thus clamping the aluminum plate. Controlling the clamping mechanisms on both sides of the base by rotating the handle ensures worker safety and prevents accidents. Attached Figure Description

[0053] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.

[0054] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.

[0055] This embodiment provides a clamping device 100 for twin-roll cast aluminum plates, mainly composed of a base 200, a clamping mechanism 300, and a driving mechanism 400. The driving mechanism 400 enables the clamping mechanism 300 to open and close. When the clamping mechanism 300 clamps the aluminum plate, the motor 205 is started to drive the rollers 206 under the base 200, thereby causing the clamping device 100 to move with the aluminum plate. This solves the problem of the risk of falling during the transfer of cast aluminum plates in the prior art, which can easily cause burns and scratches, so as to ensure the safety of workers during operation and avoid accidents.

[0056] Figure 3 This is a schematic diagram of the structure of the base 200 in the clamping device 100. The base 200 mainly includes a working platform 201, a mounting base 202, a bracket 203, support legs 204, a motor 205, rollers 206, and a crossbeam 207. As shown in the figure, the base 200 is centrally symmetrically arranged. Two crossbeams 207 are arranged parallel to each other along the width direction of the base 200. The two ends of the crossbeams 207 are respectively connected to the support legs 204. The upper end of the support legs 204 is connected to the working platform 201. The lower end of the support legs 204 has a groove, and the rollers 206 are assembled inside the groove. The output end of the motor 205 is fixedly connected to the mounting shaft of the rollers 206. The motor 205 drives the rollers 206, thereby realizing the movement of the base 200.

[0057] A mounting base 202 is welded to the center of the upper part of the work platform 201. A slot 2021 is machined at the center of the mounting base 202 for mounting the clamping mechanism 300. Threaded holes are opened on both sides of the slot 2021. A bracket 203 is provided behind the mounting base 202. The bracket 203 is welded to the work platform 201 and is symmetrically arranged along the width direction of the work platform 201. A bearing seat 2031 is formed at the end of the bracket 203 away from the work platform 201.

[0058] See Figure 1 and Figure 2 As can be seen, the drive mechanism 400 is installed below the work platform 201. The drive mechanism 400 mainly consists of a handle 401, a first gear 402, a drive shaft 403, a long connecting rod 404, a short connecting rod 405, a second gear 406, and a driven shaft 407. The first gear 402 is sleeved on the drive shaft 403, and the first gear 402 meshes with the rack 3054 of the clamping mechanism 300. The drive shaft 403 passes through the bracket 203 and is fixedly connected to the handle 401, and is installed in the bearing seat 2031 through a bearing to achieve a rotatable connection with the bracket 203. The handle 401 is located above the first gear 402, and a grip 4011 is formed at the end of the handle 401 away from the drive shaft 403. The lower end of the drive shaft 403 is formed with a connecting flange 4031. The end of the connecting flange 4031 away from the drive shaft 403 is machined with a through hole. Both ends of the long connecting rod 404 are respectively provided with through holes of the same diameter. The connecting flange 4031 is rotatably connected to one end of the long connecting rod 404 by a pin.

[0059] One end of the short connecting rod 405 has a through hole with the same diameter as the end of the long connecting rod 404. The short connecting rod 405 is movably connected to the other end of the long connecting rod 404 via a pin. The other end of the short connecting rod 405 is welded to the second gear 406, and the second gear 406 is located above the short connecting rod 405. The second gear 406 is rotatably connected to the lower part of the working platform 201. The driven shaft 407 is mounted on the bracket 203 via bearings. The driven shaft 407 has a first gear 402 sleeved at both ends. The first gear 402 sleeved at the upper end meshes with the rack 3054 of the clamping mechanism 300, and the first gear 402 sleeved at the lower end meshes with the second gear 406.

[0060] The worker rotates handle 401 by gripping handle 4011, which drives drive shaft 403 and connecting flange 4031 to rotate, causing the first gear 402 mounted on drive shaft 403 to rotate synchronously. The first gear 402 meshes with rack 3054, driving rack 3054 to move, thereby opening and closing clamping mechanism 300. Rotation of connecting flange 4031 causes long connecting rod 404 to move, which in turn drives short connecting rod 405 to rotate, thereby causing second gear 406 to rotate. Second gear 406 meshes with first gear 402 mounted on the bottom of driven shaft 407, causing driven shaft 407 to rotate, which in turn drives first gear 402 mounted on the top of driven shaft 407 to rotate. The first gear 402 at the top of the driven shaft 407 meshes with the rack 3054 in the clamping mechanism 300 installed on the other side of the base 200. Thus, by rotating the handle 401, the clamping mechanisms 300 on the left and right sides are controlled to move synchronously to clamp the cast aluminum plate.

[0061] The three-dimensional structure of the clamping mechanism 300 is as follows Figure 4 As shown in the figure, the clamping mechanism 300 mainly includes a pressure block 301, a gripper 302, a support base 303, a spring 304, and a telescopic rod 305. Figures 5 to 7 These are schematic diagrams of the clamping jaw 302, support base 303, and telescopic rod 305 in the clamping mechanism 300. (See attached diagram.) Figure 5 The gripper body 3021 is shaped like a "7". A pressure plate 3025 is welded to one end of the gripper body 3021. Threaded holes are machined on both sides of the pressure plate 3025. The other end of the gripper body 3021 is machined with a second pin hole 3023 and an installation notch 3024. The depth of the installation notch 3024 is half the thickness of the gripper body 3021. The first pin hole 3022 is opened on the gripper body 3021 between the pressure plate 3025 and the second pin hole 3023.

[0062] Depend on Figure 6 It can be seen that a second through hole 3033 is formed in the center of the support body 3031, and first through holes 3032 are formed on both sides of the second through hole 3033. The diameter of the second through hole 3033 is much larger than the diameter of the first through hole 3032. Connecting fingers 3034 are symmetrically formed on both sides of the support body 3031, and through holes are formed at the ends of the connecting fingers 3034 away from the support body 3031. A sleeve 3035 is formed at the bottom of the support body 3031. The inner diameter of the sleeve 3035 is the same as the diameter of the second through hole 3033, and a sliding groove 3036 is formed around the sleeve 3035.

[0063] See Figure 7The telescopic rod 305 is cylindrical in shape, with a stop flange 3053 formed in the circumferential direction at its center. A rack 3054 and a mounting groove 3051 are respectively machined on both sides of the stop flange 3053. A fixing hole 3052 is opened through the telescopic rod in a direction perpendicular to the mounting groove 3051.

[0064] according to Figures 4 to 7 It can be seen that the pressure block 301 is fixed to the pressure plate 3025 at the end of the gripper 302 by bolts. The two grippers 302 are installed in the mounting groove 3051 of the telescopic rod 305. The mounting notches 3024 fit together and the second pin hole 3023 is aligned with the fixing hole 3052 on the telescopic rod 305. Then, the pin is inserted to form a movable connection between the gripper 302 and the telescopic rod 305. The telescopic rod 305 is inserted into the second through hole 3033 at the center of the support 303, forming a sliding connection with the support 303. At the same time, the gripper 302 is also installed in the sliding groove 3036 of the sleeve 3035. The first pin hole 3022 of the gripper 302 is aligned with the through hole at the end of the connecting finger 3034 and the pin is inserted to form a rotatable connection between the gripper 302 and the support 303. Spring 304 is sleeved on telescopic rod 305, located between support body 3031 and stop flange 3053, and rack 3054 meshes with first gear 402 for transmission. Support body 3031 fits against mounting base 202, aligning the first through hole 3032 with the threaded hole on mounting base 202. Then, bolts are used to fix clamping mechanism 300 to mounting base 202, thus connecting clamping mechanism 300 to base 200.

[0065] Therefore, when the first gear 402 drives the rack 3054 to move, the telescopic rod 305 slides within the support 303, causing the stop flange 3053 to approach the support body 3031, and the spring 304 is compressed. The movement of the telescopic rod 305 towards the support 303 causes one end of the gripper 302 to move synchronously, and the gripper 302 rotates around the first pin hole 3022, thereby separating the mating pressure blocks 301. Then, the handle 401 is released, and the compressed spring 304 releases its elastic force, pushing the telescopic rod 305 back to its original position. The telescopic rod 305 causes one end of the gripper 302 to move away from the support 303, causing the pressure blocks 301 at the other end of the gripper 302 to close again, thus clamping the aluminum plate.

[0066] When in use, the clamping device 100 is placed under the aluminum plate. The worker rotates the handle 401, which drives the drive shaft 403 to rotate, causing the first gear 402 mounted on the drive shaft 403 to rotate synchronously. The first gear 402 meshes with the rack 3054, driving the rack 3054 to move. As a result, the telescopic rod 305 slides within the support seat 303, causing the stop flange 3053 to approach the support seat body 3031, and the spring 304 is compressed. The movement of the telescopic rod 305 towards the support seat 303 causes one end of the gripper 302 to move synchronously. The gripper 302 then rotates around the first pin hole 3022 as the center, thereby separating the mutually fitted pressure blocks 301 and opening the clamping mechanism 300.

[0067] The rotation of the drive shaft 403 causes the long connecting rod 404 to move, which in turn drives the short connecting rod 405 to rotate, thereby causing the second gear 406 to rotate. The second gear 406 meshes with the first gear 402 sleeved at the bottom of the driven shaft 407, causing the driven shaft 407 to rotate, which in turn drives the first gear 402 sleeved at the top of the driven shaft 407 to rotate. The first gear 402 at the top of the driven shaft 407 meshes with the rack 3054 in the clamping mechanism 300 installed on the other side of the base 200, thereby opening the clamping mechanism 300 on the other side of the base 200. Then, the handle 401 is released, and the compressed spring 304 releases its elastic force, pushing the telescopic rod 305 back to its original position. The telescopic rod 305 then drives one end of the gripper 302 to move backward, causing the pressure block 301 at the other end of the gripper 302 to close again, clamping the aluminum plate. Subsequently, the motor 205 is started, causing the roller 206 to rotate, thereby driving the base 200 to move the aluminum plate to the next work station.

[0068] Therefore, by rotating the handle 401 on one side, the clamping mechanisms 300 on both sides are controlled to move synchronously to clamp the cast aluminum plate, ensuring the safety of the workers and preventing accidents.

[0069] The above embodiments are merely a more detailed description of the present utility model. For those skilled in the art, modifications or equivalent substitutions can still be made to the technical solutions in the foregoing embodiments. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model patent.
