Grabbing and clamping mechanism for aluminum formwork reinforcing ribs

Abstract

The utility model discloses an aluminum template reinforcing rib grabbing and clamping mechanism which comprises two sets of clamping assemblies arranged oppositely, each clamping assembly comprises a linear driving device, a positioning plate is fixed to the driving end of each linear driving device, a sliding groove is formed in the surface of the side, away from the corresponding linear driving device, of each positioning plate, and the clamping assemblies are arranged in the sliding grooves. A sliding block is connected into the sliding groove in a sliding mode, an elastic piece is fixed to the top of the sliding block, the elastic piece is fixed to the top in the sliding groove, and a clamping plate used for clamping a reinforcing rib is fixed to one end of the sliding block. Compared with the prior art, after the clamping plates clamp the reinforcing ribs, if the reinforcing ribs are too long, large counter-acting force can be applied to the clamping plates due to the fact that the reinforcing ribs make contact with the inner walls of the two sides of the aluminum formwork, and therefore the sliding blocks overcome the elastic force of the elastic pieces to slide upwards; therefore, the reinforcing ribs cannot continue to descend along with descending of the mechanical arm, and the situation that the two sides of the aluminum formwork protrude outwards due to the fact that the reinforcing ribs are forcibly clamped into the aluminum formwork is avoided.

Description

Technical Field

[0001] The utility model relates to the technical field of production of building aluminum templates, in particular to a grabbing and clamping mechanism for aluminum template reinforcement ribs. Background Art

[0002] Aluminum formwork is one of the commonly used building formworks. Since it is made of aluminum material, the overall weight of the formwork is relatively light. During the production process of the aluminum formwork, in order to increase the strength of the aluminum formwork, reinforcing ribs are welded on the inside of the aluminum formwork.

[0003] Welding reinforcement ribs is generally done in an automated process, where a robotic arm uses a gripping and clamping mechanism to clamp the aluminum formwork and snap the reinforcement ribs into the designated position inside the aluminum formwork. The reinforcement ribs are then welded to the aluminum formwork using welding equipment. During this process, if the reinforcement ribs are too long to fit into the aluminum formwork, the robotic arm's lowering stroke does not change. Therefore, the reinforcement ribs are often forcibly snapped into the aluminum formwork, causing the sides of the aluminum formwork to deform and bulge outward, rendering the aluminum formwork scrapped. Utility Model Content

[0004] The main purpose of the utility model is to provide a grabbing and clamping mechanism for the reinforcement ribs of the aluminum formwork. After the clamping plate clamps the reinforcement ribs, if the length of the reinforcement ribs is too long, the reinforcement ribs will exert a large reaction force on the clamping plate due to the inner walls on both sides of the aluminum formwork that are in contact with them, thereby causing the slider to overcome the elastic force of the elastic part and slide upward, so that the reinforcement ribs will not continue to descend as the robotic arm descends, so as to avoid the reinforcement ribs being forcibly engaged into the aluminum formwork and causing the two sides of the aluminum formwork to bulge outward.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A grabbing and clamping mechanism for aluminum formwork reinforcement ribs includes two groups of relatively arranged clamping components, the clamping components include a linear drive device, a positioning plate is fixed to the driving end of the linear drive device, a sliding groove is provided on the surface of the positioning plate on the side away from the linear drive device, a slider is slidably connected in the sliding groove, an elastic part is fixed to the top of the slider, and the elastic part is fixed to the top of the sliding groove, and a clamping plate for clamping the reinforcement ribs is fixed to one end of the slider.

[0007] Furthermore, a positioning hole is provided at the top of the sliding block, a positioning rod is slidably inserted into the positioning hole, and both ends of the positioning rod are fixed on the inner wall of the sliding groove.

[0008] Furthermore, a limiting plate is fixed on the top of the clamping plate, and the limiting plate is used to contact the top of the reinforcing rib.

[0009] Furthermore, the top of the limiting plate in contact with the top of the reinforcing rib is threadedly connected to a limiting screw.

[0010] Further, the elastic member is a cylindrical spring.

[0011] Further, the linear driving device is an electric cylinder or a pneumatic cylinder.

[0012] Further, a connecting frame is further included, and bottom portions of the connecting frame are fixedly connected to the linear driving devices of the two groups of clamping assemblies.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] After the clamping plate clamps the reinforcing rib, if the length of the reinforcing rib is too long, the reinforcing rib will be in contact with the inner walls on both sides of the aluminum formwork, thereby exerting a large reaction force on the clamping plate, so that the sliding block slides upward to overcome the elastic force of the elastic member, and the reinforcing rib will not continue to drop with the mechanical arm, thereby avoiding the situation that the reinforcing rib is forcibly clamped into the aluminum formwork and causes the two sides of the aluminum formwork to protrude outward.

[0015] The limiting plate of the utility model will be in contact with the top of the reinforcing rib, so that when the reinforcing rib is installed into the aluminum formwork, the force acting on the reinforcing rib will be transmitted to the limiting plate, thereby avoiding the situation that the reinforcing rib moves upward relative to the clamping plate after being clamped and fixed by the clamping plate 1.

[0016] The bottom height of the limiting screw can be adjusted, so that when the clamping plate clamps reinforcing ribs of different heights, the limiting screw can resist the top of the reinforcing rib to limit the reinforcing rib. BRIEF DESCRIPTION OF DRAWINGS

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, purposes and effects realized by the utility model easy to understand, the utility model is further described below in combination with specific implementation manners.

[0022] As shown in Figures 1-3 , a kind of aluminum formwork reinforcing bar grabbing clamping mechanism, including two sets of oppositely arranged clamping components 1, clamping component 1 includes linear drive device 105, the driving end of linear drive device 105 is fixed with positioning plate 103, the side surface of positioning plate 103 away from linear drive device 105 is equipped with sliding groove 106, sliding groove 106 is slidably connected with sliding block 102, the top of sliding block 102 is fixed with elastic element 101, elastic element 101 is fixed to the top in sliding groove 106, the one end of sliding block 102 is fixed with the clamping plate 104 for clamping reinforcing bar, elastic element 101 is cylindrical spring, linear drive device 105 is electric cylinder or air cylinder.

[0023] In the embodiment, as shown in Figure 1 , two linear drive devices 105 are oppositely arranged, so when the driving end of two sets of linear drive devices 105 works, it will drive two sets of positioning plates 103 to approach, so that two sets of clamping plates 104 clamp reinforcing bar, and then the clamping reinforcing bar is engaged into the inner wall of aluminum formwork using mechanical arm, if the length of reinforcing bar is too long, reinforcing bar will exert greater reaction force on clamping plate 104 due to contact with the inner wall of aluminum formwork on both sides during the process of reinforcing bar descending driven by mechanical arm, so that sliding block 102 slides upward to compress elastic element 101, so that reinforcing bar will not continue to descend with the descent of mechanical arm, to avoid the outward bulging of both sides of aluminum formwork caused by forcibly engaging reinforcing bar into aluminum formwork.

[0024] And when the length of reinforcing bar is in the required interval, although both ends of reinforcing bar contact with the inner wall of aluminum formwork on both sides, the reaction force exerted on clamping plate 104 is not enough to make sliding block 102 overcome the elastic force of elastic element 101, so as to ensure that reinforcing bar can be installed to the specified position inside aluminum formwork under the action of mechanical arm.

[0025] As shown in Figure 1 and Figure 2 , positioning hole 6 is formed in the top of sliding block 102, positioning rod 5 is slidably inserted into positioning hole 6, and both ends of positioning rod 5 are fixed on the inner wall of sliding groove 106. Sliding block 102 will slide in sliding groove 106 under force, and during sliding, since positioning rod 5 penetrates sliding block 102, positioning rod 5 can make sliding block 102 slide up and down along the specified path during sliding, so as to ensure that clamping plate 104 also moves up and down along the specified path.

[0026] As shown in Figure 1 and Figure 3As shown, a limiting plate 3 is fixed on the top of the clamping plate 104. When the clamping plate 104 clamps the reinforcing rib, the limiting plate 3 will contact the top of the reinforcing rib. Therefore, when the reinforcing rib is installed inside the aluminum formwork, the force acting on the reinforcing rib will be transmitted to the limiting plate 3, thereby preventing the reinforcing rib from moving upward relative to the clamping plate 104 after being clamped and fixed by the clamping plate 104.

[0027] Among them, Figure 3 As shown, the top of the limit plate 3 in contact with the top of the reinforcing rib is threadedly connected to the limit screw 4. Rotating the limit screw 4 changes the height of the bottom of the limit screw 4, so that when the clamping plate 104 clamps reinforcing ribs of different heights, the limit screw 4 can all resist the top of the reinforcing rib.

[0028] Among them, Figure 1 As shown, it also includes a connecting frame 2, the bottom of which is fixedly connected to the linear drive device 105 of the two groups of clamping components 1. The connecting frame 2 is connected to the robotic arm, and the robotic arm is used to move the mechanism.

[0029] Working principle: First, use the connecting frame 2 to connect and fix this mechanism to the robotic arm. When grabbing and clamping the reinforcement rib, the robotic arm electrically moves this mechanism, so that the two clamping plates 104 are aligned with the two sides of the reinforcement rib. Then, the robotic arm drives this mechanism down until the reinforcement rib is located between the two sets of clamping plates 104. Next, the linear drive device 105 drives the two sets of clamping plates 104 close together through the positioning plate 103, thereby clamping and fixing the reinforcement rib. Then, the robotic arm puts the clamped reinforcement rib into the inside of the aluminum template. In this process, if the length of the reinforcement rib is too long, then in the process of the robotic arm driving the reinforcement rib to descend, the reinforcement rib will exert a large reaction force on the clamping plate 104 due to the contact with the inner walls on both sides of the aluminum template, thereby causing the slider 102 to slide upward and compress the elastic part 101, so that the reinforcement rib will not continue to descend as the robotic arm descends, so as to avoid the reinforcement rib being forced into the aluminum template and causing the two sides of the aluminum template to bulge outward.
