Specific implementation manners

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the specification drawings of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts shall fall within the protection scope of the present utility model.

[0022] Refer to Figures 1 - 4, an embodiment provided by the present utility model: a multi-claw synchronous mechanical structure, including a frame 1, an X-axis driving mechanism 3 is installed on the top of the frame 1, a Z-axis driving mechanism 4 is installed on the X-axis driving mechanism 3, and a claw mechanism 2 is installed at the bottom of the Z-axis driving mechanism 4. The claw mechanism 2 includes a bottom plate 230, a left fixing plate 201 and a right fixing plate 203. The bottom sides of the left fixing plate 201 and the right fixing plate 203 are both slidably connected to the upper surface of the bottom plate 230. A left rack 206 is installed on the upper surface of the middle part of the left fixing plate 201, and a right rack 204 is embedded in the middle part of the right fixing plate 203. A gear 205 is rotatably connected to the middle of the bottom plate 230. The adjacent sides of the right rack 204 and the left rack 206 are respectively meshed and connected to both sides of the teeth of the gear 205. A cylinder 202 is installed on the upper surface of the left fixing plate 201, and the output end of the cylinder 202 is connected to the right fixing plate 203. A plurality of uniformly distributed left claws 207 are fixedly connected to one side of the left fixing plate 201, and a plurality of uniformly distributed right claws 208 are fixedly connected to one side of the right fixing plate 203. The right claws 208 and the left claws 207 are alternately distributed.

[0023] Specifically, the X-axis driving mechanism 3 is used to drive the Z-axis driving mechanism 4 to move along the X-axis, and then drive the claw mechanism 2 to move along the X-axis. The Z-axis driving mechanism 4 is used to drive the claw mechanism 2 to move along the Z-axis. The claw mechanism 2 is used to synchronously clamp a plurality of workpieces, which is convenient for clamping and moving the workpieces. By driving the right fixing plate 203 to move axially along the bottom plate 230 by the cylinder 202, the right rack 204 drives the gear 205 to rotate, causing the left rack 206 to move, and further driving the left fixing plate 201 to move in the opposite direction to the right fixing plate 203 along the axial direction of the bottom plate 230, so that the left claws 207 on the left fixing plate 201 and the right claws 208 on the right fixing plate 203 are synchronously opened and closed, and a plurality of products can be clamped at the same time, solving the problem that the synchronization of the existing multi-claw actions is poor and the workpieces often fall.

[0024] Reference Figure 3 and Figure 4 , a relief hole is provided at the middle part of the left fixing plate 201 adjacent to the left rack 206, and the gear 205 is located above the relief hole of the left fixing plate 201. It is convenient for both sides of the gear 205 to be meshed and connected to the right rack 204 and the left rack 206 respectively.

[0025] Reference Figure 1, the X-axis driving mechanism 3 includes an X-axis electric slide rail 301 and a sliding support frame 302. The bottom of the X-axis electric slide rail 301 is fixedly connected to the top of the frame 1, and the top of the X-axis electric slide rail 301 is connected to the sliding support frame 302 and can drive the sliding support frame 302 to move along the X-axis direction. The X-axis electric slide rail 301 adopts an existing electric slide rail, which can be provided by a supplier and is an existing conventional technology, so it will not be elaborated too much. In this application, the X-axis electric slide rail 301 can be used to make the sliding support frame 302 move along the X-axis direction, aiming to realize that the X-axis driving mechanism 3 drives the Z-axis driving mechanism 4 to move along the X-axis.

[0026] Reference Figures 1 - 2 , the Z-axis driving mechanism 4 includes a Z-axis motor 405. The outside of the Z-axis motor 405 is fixedly connected to the inner side of the sliding support frame 302. A Z-axis gear is fixedly connected to the output end of the Z-axis motor 405, and a Z-axis rack 403 is meshed and connected to one side of the Z-axis gear. A fixed bracket 401 is fixedly connected to one side of the Z-axis rack 403, a Z-axis guide rail 402 is fixedly connected to one side of the fixed bracket 401, a Z-axis slider 404 is slidably connected to one side of the Z-axis guide rail 402, and the outside of the Z-axis slider 404 is fixedly connected to the inner side of the sliding support frame 302.

[0027] Specifically, the Z-axis motor 405 is supported and fixed by the sliding support frame 302. By driving the rotation of a Z-axis gear (not shown in the figure) by the Z-axis motor 405 to drive the Z-axis rack 403 to move along the Z-axis, the Z-axis guide rail 402 and the Z-axis slider 404 play a guiding and stabilizing role, and then the fixed bracket 401 can be driven to move along the Z-axis direction, realizing that the Z-axis driving mechanism 4 can drive the jaw mechanism 2 to move along the Z-axis direction.

[0028] There are two fixed brackets 401, and each fixed bracket 401 is provided with a Z-axis guide rail 402 and a Z-axis slider 404. One side of the Z-axis rack 403 is fixedly connected to one of the fixed brackets 401. The two fixed brackets 401 are provided to increase the stability when the jaw mechanism 2 moves along the Z-axis direction.

[0029] The bottom of the fixed bracket 401 is fixedly connected to a through hole in the middle of one side of the bottom plate 230. A plurality of first slide rails 231 are fixedly connected to the side of the bottom plate 230 away from the fixed bracket 401. A first slider 232 is slidably connected to the top of the first slide rail 231, and the top of the first slider 232 is fixedly connected to the bottom surface of the right fixing plate 203. A plurality of second slide rails 241 are fixedly connected to the edge of the side of the bottom plate 230 away from the fixed bracket 401. A second slider 242 is slidably connected to the top of the second slide rail 241, and the top of the second slider 242 is fixedly connected to the bottom surface of the left fixing plate 201.

[0030] Specifically, the first slide rail 231 and the first slider 232 can play a role in stabilizing the right fixed plate 203; the second slide rail 241 and the second slider 242 can play a role in stabilizing the left fixed plate 201.

[0031] Limit slots 221 are provided on both sides of the middle part of the right fixed plate 203, and limit posts 220 are fixedly connected to both sides of the middle part of the bottom plate 230. The limit posts 220 are located in the corresponding limit slots 221. Limit seats 211 are fixedly connected to both sides of the middle part of the bottom plate 230 and at the positions on both sides of the gear 205. A limit block 210 is fixedly connected to the middle part of the limit seat 211. The above design is used to limit the movement of the left fixed plate 201 and the right fixed plate 203, thereby increasing the stability of the left claw 207 and the right claw 208 and preventing the workpiece from being pinched.

[0032] Working principle: The cylinder 202 drives the right fixed plate 203 to move axially along the bottom plate 230. The right rack 204 in the right fixed plate 203 drives the gear 205 to rotate, which drives the left rack 206 on one side of the left fixed plate 201 to move, and then drives the left fixed plate 201 to move in the opposite direction to the right fixed plate 203 along the axis of the bottom plate 230, so that the left claw 207 provided on the left fixed plate 201 and the right claw 208 on the right fixed plate 203 open and close synchronously, and can clamp multiple products. A single cylinder 202 is used as the driving source to simultaneously control multiple left claws 207 and right claws 208. Each pair of opposite left claws 207 and right claws 208 cooperate to form a clamping jaw that can clamp the workpiece, rather than each clamping jaw being equipped with an independent finger cylinder, which can reduce the number of components and maintenance costs and improve stability and reliability.

[0033] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
