A limit block is provided at the top of the workbench. Rotating handles are fixedly provided at the top of both screw rods, and guide pressing plates are rotatably provided at the bottom of the screw rods. The bottom ends of the four guide shafts respectively pass through two extension plates and are fixedly installed at the top of the two guide pressing plates. The above-mentioned prior art solutions have the following deficiencies: When fixing a single composite board, this device needs to perform three separate operations before it can limit the composite board in the left-right and up-down directions. The convenience of its operation is average, so there is a certain room for improvement. Content of the Utility Model

[0004] The purpose of the utility model is to provide a splicing positioning device for composite plywood to solve the problem that the existing composite plywood is not easy to be directly limited and fixed at one time during splicing as mentioned in the above background technique.

[0022] Please refer to Figures 1-4 , an embodiment provided by the present invention: a composite plywood splicing and positioning device, including a positioning table 1, and a fixed clamping plate 6 is installed on one side of the top of the positioning table 1;

[0023] A bidirectional lead screw 8 penetrates through the inside of the fixed clamping plate 6, and one end of the bidirectional lead screw 8 extends to the outside of the fixed clamping plate 6 and is installed with a turning handle 11. Movable sleeves 9 are sleeved on both ends of the bidirectional lead screw 8, and driving mechanisms 7 are arranged at the bottom ends of the movable sleeves 9;

[0024] The driving mechanism 7 includes a movable plate 701 installed at the bottom end of the movable sleeve 9, and one end of the movable plate 701 extends to the outside of the fixed clamping plate 6. The cross-section of the movable plate 701 is L-shaped. An electric push rod 702 is installed inside the movable plate 701, and a push plate 703 is installed at one end of the electric push rod 702. Limit guide rods 704 are installed at both ends of the push plate 703 close to one side of the movable plate 701, and one ends of the limit guide rods 704 penetrate through the inside of the movable plate 701;

[0025] There are two movable plates 701 in total, and the two movable plates 701 are symmetrically distributed with respect to the central axis of the fixed clamping plate 6;

[0026] The bottom end of the push plate 703 abuts against the top end of the positioning table 1. The push plate 703 and the movable plate 701 form a sliding structure through the cooperation of the limit guide rods 704;

[0027] Specifically, as Figure 1 、 Figure 2 and Figure 3 shown, when in use, the cooperation of the two movable plates 701 and the push plate 703 is utilized to facilitate the mutual approach of the two composite plywood boards, so as to dock the two composite plywood boards. At the same time, the telescopic action of the electric push rod 702 is utilized to facilitate the adjustment of the pushing distance of the push plate 703, so as to improve its scope of application;

[0028] Moreover, buffer strips II 10 are installed at equal intervals inside the fixed clamping plate 6. An adjustment groove 2 is opened on one side of the top end of the positioning table 1 away from the fixed clamping plate 6. An electric telescopic rod 3 is installed on one side of the adjustment groove 2 close to the fixed clamping plate 6. A sliding block 4 is installed at one end of the electric telescopic rod 3. A guide rod 12 penetrates through the inside of the sliding block 4. At the same time, both ends of the guide rod 12 are connected to the inner wall of the adjustment groove 2. A limit mechanism 5 is arranged at the top end of the sliding block 4, and the position of the limit mechanism 5 corresponds to the inside of the fixed clamping plate 6;

[0029] The limit mechanism 5 includes a connecting plate 501 installed at the top end of the sliding block 4. Side clamping plates 502 are welded on both sides of the connecting plate 501. A plurality of buffer strips I 503 are installed at equal intervals on one side of the two side clamping plates 502 close to the fixed clamping plate 6. At the same time, the bottom ends of the side clamping plates 502 abut against the top end of the positioning table 1;

[0030] The buffer strip I 503 has the same cross-sectional size as the fixed clamping plate 6. The cross-section of the buffer strip I 503 is a right trapezoid, and the short bottom side of the right trapezoid is located at the lower part;

[0031] Specifically, as Figure 1 、 Figure 2 and Figure 4As shown, during use, the cooperation between the side clamping plates 502 and the fixed clamping plate 6 is utilized to achieve the left and right limiting of the composite plywood. At the same time, the special structures of the side clamping plates 502 and the fixed clamping plate 6 are used to synchronously achieve the up and down limiting effect on the composite plywood, thereby reducing the operation steps.

[0032] Working principle: When the present utility model is in use, first, two composite plywoods are respectively placed on both sides of the adjustment groove 2. Then, the electric telescopic rod 3 is started to shorten, so that the electric telescopic rod 3 pulls the sliding block 4 to approach the fixed clamping plate 6 along the guide rod 12, making the connecting plate 501 move synchronously, and driving the two side clamping plates 502 to approach one side of the composite plywood until the side clamping plates 502 are respectively in tight contact with one side of a composite plywood. As the electric telescopic rod 3 continues to shorten, the side clamping plates 502 push the composite plywood towards the fixed clamping plate 6 to achieve the left and right limiting and fixing of the composite plywood by the side clamping plates 502 and the fixed clamping plate 6.

[0033] Secondly, the clamping sides of the side clamping plates 502 and the fixed clamping plate 6 are inclined planes. When they fix the composite plywood left and right, they synchronously drive the second buffer strip 10 and the first buffer strip 503 to fix the side of the composite plywood, and utilize the characteristics of the inclined planes to hinder the upward movement of the composite plywood, thereby synchronously achieving the up and down fixing effect on the composite plywood.

[0034] Finally, rotate the handle 11 to make the bidirectional lead screw 8 rotate, and then make the two movable sleeves 9 approach each other, so as to drive the two movable plates 701 to approach each other, thereby making the push plate 703 abut against the outer side of the corresponding composite plywood, and then playing a role in pushing the two composite plywoods to approach and join together. At the same time, the telescopic movement of the electric push rod 702 is utilized to further adjust the pushing distance of the two push plates 703 for the composite plywood to achieve the joining effect of composite plywoods of different lengths.
