DETAILED DESCRIPTION

[0020] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0021] like Figures 1 to 6 As shown, an embodiment of the utility model proposes a negative pressure clamp quick-install structure, which includes a load-bearing arm 1; movable arms 2, which are in two groups and are movably arranged at both ends of the load-bearing arm 1 through an adjusting mechanism, and each of the two ends of the movable arm 2 is provided with an adsorption device with an adjustable position, wherein the adjusting mechanism is used to adjust the relative distance between the two movable arms 2, and the adsorption device is used to adsorb the mold 100; a folding mechanism, which is arranged at one end of the load-bearing arm 1, is used to adjust the rotation angle of the load-bearing arm 1; sink grooves 104 are provided at both ends of the load-bearing arm 1, and each movable arm 2 is respectively located in the corresponding sink groove 104, and each sink groove 104 is provided with a T-slot 105, and each movable arm 2 is provided with a T-block 202, and the T-blocks 202 are respectively slidably arranged in the corresponding T-slot 105.

[0022] The detailed working process of this embodiment is as follows: by arranging movable arms 2 with adjustable relative positions and adsorption devices that can move on the movable arms 2 at both ends of the load-bearing arms 1, the relative positions of the two movable arms 2 are adjusted by an adjusting mechanism to change the positions of the two movable arms 2 and the adsorption devices to meet the adsorption and clamping of molds of different sizes, improve the stability of the negative pressure clamp, and avoid the problem of being unable to stably clamp the mold due to the mold being too large and the adsorption force area being too small, or the mold being too small and the relative distance of the adsorption devices on the clamp being too far. At the same time, the folding mechanism can rotate the load-bearing arm 1 to different angles and then fix it to meet different work requirements.

[0023] Under the arrangement of the T-slot 105 and the T-block 202 , the movable arm 2 is arranged in the sinking groove 104 and can slide within the range of the sinking groove 104 .

[0024] like Figures 2 to 6As shown, each adsorption device includes a suction cup 4 and an air pipe 401, one end of the air pipe 401 is connected to the suction cup 4, a stud 402 is provided on the suction cup 4, and a travel groove 201 is opened at both ends of each movable arm 2. The stud 402 is located in the corresponding travel groove 201, and a butterfly nut 404 is threadedly connected to the stud 402, wherein the butterfly nut 404 abuts against the movable arm 2.

[0025] The detailed working process of this embodiment is as follows: the function of the suction cup 4 is to adsorb the mold, the air pipe 401 is connected to the vacuum pump, and the adsorption of the suction cup 4 is controlled by the vacuum pump. A stud 402 is provided on the upper end of the suction cup 4, and the stud 402 can slide in the stroke groove 201 to adjust the relative position of each suction cup 4 on the corresponding movable arm 2, and the butterfly nut 404 is used to fix the position of the suction cup 4 on the movable arm 2. When fixing, just tighten the butterfly nut 404 to make it abut against the movable arm 2. When the position of the suction cup 4 needs to be adjusted, just loosen the butterfly nut 404.

[0026] like Figures 2 to 6 As shown, mounting surfaces 403 are provided on both sides of the stud 402 , and both mounting surfaces 403 are located in the travel groove 201 and abut against the travel groove 201 .

[0027] The detailed working process of this embodiment is as follows: mounting surfaces 403 are opened on both sides of the stud 402, so that the upper end of the stud 402 is in the shape of a rectangular column, and a step is formed at the intersection of the cylinder and the rectangular column. The rectangular column is located in the travel groove 201 and is restricted by the travel groove 201, so that it can only move in the travel groove 201 and cannot rotate, thereby preventing the suction cup 4 from rotating with the butterfly nut 404 when the butterfly nut 404 is turned, affecting the use. The step abuts against the lower end of the movable arm 2, and the butterfly nut 404 on the rectangular column abuts against the upper end of the movable arm 2, so that the suction cup 4 can be fixed on the movable arm 2.

[0028] like Figure 5 As shown, the adjustment mechanism includes two groups of screw rods 5, and the two screw rods 5 are rotatably arranged in the load-bearing arm 1, and the two screw rods 5 are respectively located in two sinking grooves 104, wherein the two screw rods 5 are respectively threadedly connected with each movable arm 2, a countersunk hole 102 is opened in the middle of the load-bearing arm 1, and a hexagonal prism 501 is rotatably arranged in the countersunk hole 102, and bevel gears 502 are arranged at the ends of the two screw rods 5 close to each other and at one end of the hexagonal prism 501, and the three groups of bevel gears 502 are meshed with each other.

[0029] The detailed working process of this embodiment is as follows: the function of the two sets of screw rods 5 is to drive the movable arms 2 in the relative grooves 104, and the hexagonal prism 501 is the driving source. By rotating the bevel gear 502 on the hexagonal prism 501, the bevel gears 502 at the ends of the two sets of screw rods 5 are driven to rotate, thereby driving the two sets of screw rods 5 to rotate. Since the two sets of screw rods 5 are driven by the same bevel gear 502, the thread rotation directions of the two sets of screw rods 5 need to be relatively set to meet the requirements that when the hexagonal prism 501 is rotated to drive the two sets of screw rods 5, the two driven movable arms 2 move away from or approach each other.

[0030] like Figure 2 and Figure 3 As shown, the folding mechanism includes a connecting arm 3, a connecting seat 103 and two toothed discs 302, wherein the connecting seat 103 is arranged at one end of the load-bearing arm 1, and the two toothed discs 302 are arranged at one end of the connecting arm 3, wherein the connecting seat 103 is clamped between the two toothed discs 302 and is connected by a screw rod 301 with a handle, and the connecting arm 3 is used to connect the power equipment and the load-bearing arm 1.

[0031] The detailed working process of this embodiment is as follows: one end of the connecting arm 3 is connected to a robotic arm-type device, and the other end has two toothed discs 302. The connecting seat 103 at one end of the load-bearing arm 1 is clamped in the middle through the two toothed discs 302, and is connected through a handle screw rod 301. Under the action of the handle screw rod 301, the two toothed discs 302 are meshed and clamped with the connecting seat 103 to make them stably connected. Under the setting of the two toothed discs 302 and the connecting seat 103, the angle between the connecting arm 3 and the load-bearing arm 1 can be controlled to meet different work requirements. When the load-bearing arm 1 needs to be rotated, only the handle screw rod 301 needs to be loosened, and the two toothed discs 302 will unfold under their own elastic force, so that the two toothed discs 302 are loosened from the connecting seat 103, and the load-bearing arm 1 can be rotated. After rotating to the desired position, the handle screw rod 301 is tightened to press the two toothed discs 302 to engage with the connecting seat 103.

[0032] like Figure 2 As shown, the load-bearing arm 1 is provided with multiple sets of fixing rings 101 , and the air pipe 401 is located inside the fixing rings 101 .

[0033] The detailed working process of this embodiment is as follows: the function of the fixing ring 101 is to regulate the multiple groups of air pipes 401 to prevent the multiple groups of air pipes 401 from being scattered on the load-bearing arm 1.

[0034] like Figure 1 As shown, scale lines are provided on the load-bearing arm 1 .

[0035] The detailed working process of this embodiment is as follows: the role of the scale line is to facilitate intuitive observation and adjustment of the position of the movable arm 2.

[0036] The implementation principle of the embodiment of the present application is: first, the two movable arms 2 on the load-bearing arm 1 are adjusted according to the mold. During adjustment, the bevel gear 502 on the hexagonal prism 501 is rotated to drive the bevel gears 502 at the ends of the two sets of screws 5 to rotate, thereby driving the two sets of screws 5 to rotate and drive the two movable arms 2 to move away from or closer to each other. Secondly, the suction cup 4 is adjusted. The suction cup 4 on the movable arm 2 can be adjusted by loosening the butterfly nut 404. When fixing, only the butterfly nut 404 needs to be tightened to make it abut against the movable arm 2.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
