In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0026] See Figures 1 to 3A tool clamping device shown in a preferred embodiment of the present application includes a conveyor frame 1 and a clamping mechanism 2. The conveyor frame 1 is provided with a tool plate 3 that can move in the horizontal direction. The clamping mechanism 2 is used to clamp the movable tool plate 3. It is arranged on the side of the conveyor frame 1 and can be moved in the horizontal direction in a controlled manner. The clamping mechanism 2 includes a first clamping assembly 21, a driving cylinder 22, and a second clamping assembly 23. The first clamping assembly 21 includes a fixed sleeve 211, a camshaft 212 that is movably arranged in the fixed sleeve 211, and a first clamping block 213 connected to one end of the camshaft 212. The camshaft 212 is provided with a plurality of guide grooves 2121. The fixed sleeve 211 is provided with a plurality of guide pins 2111 that respectively correspond to the plurality of guide grooves 2121. The guide grooves 2121 cooperate with the guide pins 2111 to enable the camshaft 212 to drive the first clamping block 213 to achieve both linear and rotational motion. The movable end of the driving cylinder 22 is rotatably connected to one end of the camshaft 212. The second clamping assembly 23 includes a connecting shaft 231 and a second clamping block 232 sleeved on one end of the connecting shaft 231 . The connecting shaft 231 is telescopically connected to the other end of the cam shaft 212 and can rotate synchronously with the cam shaft 212 .

[0027] According to the solution of the embodiment of the present utility model, the camshaft 212 is pushed forward by driving the oil cylinder 22, and the camshaft 212 drives the first clamping block 213 to realize both linear and rotational movements under the cooperation of the guide groove 2121 and the guide pin 2111, so that the first clamping block 213 is close to the tooling plate 3 and abuts against one side of the tooling plate 3. At the same time, the second clamping block 232 rotates together with the camshaft 212 and the first clamping block 213, and the first clamping block 213 and the second clamping block 232 move at the same time to cooperate and abut against both sides of the tooling plate 3, thereby achieving the purpose of quickly and stably clamping the tooling plate 3. It should be noted that, in the initial state, the first clamping block 213 and the second clamping block 232 are respectively located on both sides of the tooling plate 3 and are in a vertical state to avoid the tooling plate 3 being installed and placed on the conveyor line. The second clamping block 232 is close to one side of the tooling plate 3. When the tooling plate 3 is quickly clamped, the first clamping block 213 is driven by the camshaft 212 to approach the other side of the tooling plate 3 and rotate until it is in contact with the other side of the tooling plate 3. At the same time, the second clamping block 232 is driven by the connecting shaft 231 to rotate synchronously with the first clamping block 213 and abut against one side of the tooling plate 3, thereby quickly clamping the tooling plate 3. After clamping the tooling plate 3, the clamping mechanism 2 drives the tooling plate 3 to move and convey it as a whole in the horizontal direction.

[0028] The following is a detailed description with specific embodiments:

[0029] See Figure 1The conveyor frame 1 is provided with multiple tooling plates 3 in the center, and two sets of clamping mechanisms 2 are provided on either side of the conveyor frame 1. Each set of clamping mechanisms 2 includes multiple clamping mechanisms 2 corresponding to the multiple tooling plates 3. Each tooling plate 3 is rapidly clamped and moved more stably by a pair of clamping mechanisms 2 on either side. Specifically, in this embodiment, linear motors are provided on either side of the conveyor frame 1 to drive the two sets of clamping mechanisms 2 for movement. Furthermore, an oil seal assembly is provided between one end of the camshaft 212 and the movable end of the drive cylinder 22 for sealing.

[0030] See Figure 3 The other end of the camshaft 212 is provided with a connecting rod 214, and the other end of the connecting shaft 231 is provided with a connecting sleeve 233. The connecting rod 214 is retractably limited within the connecting sleeve 233. Specifically, in this embodiment, the connecting sleeve 233 is provided with a limiting groove 2331, and the connecting rod 214 is provided with a limiting rod 2141. The limiting rod 2141 is horizontally movable within the limiting groove 2331. The second clamping assembly 23 also includes two fixed seats 234. The connecting sleeve 233 and the connecting shaft 231 are both provided on the fixed seats 234 and are rotatably connected to the fixed seats 234. Since the second clamping block 232 is close to one side of the tooling plate 3, it only needs to rotate to abut against the side of the tooling plate 3, so no horizontal movement is required. Therefore, by setting the connecting rod 214 to telescopically move in the connecting sleeve 233, the camshaft 212 can only drive the connecting shaft 231 and the second clamping block 232 to rotate synchronously, and will not drive the second clamping block 232 to move synchronously in a straight line. At the same time, a fixed seat 234 is set to fix the connecting sleeve 233 and the connecting shaft 231 to further position and fix the horizontal position of the second clamping block 232, ensuring that the second clamping block 232 can abut the tooling plate 3 after rotation and cooperate with the first clamping block 213 to clamp the tooling plate 3.

[0031] See Figure 3 The guide groove 2121 includes a rotating portion 2122 and a straight portion 2123. The rotating portion 2122 is used to cooperate with the guide pin 2111 to drive the camshaft 212 to rotate. Specifically, in this embodiment, the axis of the rotating portion 2122 intersects with the axis of the straight portion 2123 at an obtuse angle. The rotating portion 2122 is provided to enable the camshaft 212 to drive the first clamping block 213 to rotate to the target angle so that it can be clamped to one side of the tooling plate 3. The straight portion 2123 is provided so that after the first clamping block 213 rotates to the target angle, it can move linearly close to the side of the tooling plate 3 and abut against the tooling plate 3. Specifically, in this embodiment, three guide grooves 2121 are provided on the camshaft 212. Correspondingly, three guide pins 2111 that cooperate with the guide grooves 2121 are provided on the fixed sleeve 211.

[0032] See Figure 1At least one set of transmission rollers 4 is provided between the conveyor frame 1 and the tooling plate 3. The transmission rollers 4 are used to drive the tooling plate 3 to move horizontally. The transmission rollers 4 are provided to assist the clamping mechanism 2 in driving the tooling plate 3 to move smoothly in the horizontal direction.

[0033] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
