All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In order to enhance the understanding of the solution of the present invention, the technical problems need to be elaborated in combination with the related technologies, and the specific contents are as follows:
in the production process of products such as reinforcement cages, reinforcement nets and the like, some automatic equipment is required to be used for conveying the reinforcement. Taking a railway track slab reinforcement cage as an example, a row of longitudinal reinforcement ribs on the side surface of the reinforcement cage need to penetrate into the reinforcement cage simultaneously for binding.
However, after the steel bar grabbing device in the related art grabs the longitudinal steel bar, due to the influence of the rib height of the steel bar, the longitudinal steel bar slips, deflects around the grabbing position and deviates, so that the steel bar cannot be accurately penetrated into the steel bar cage.
In order to alleviate the above technical problems, the present invention provides a gripping device for steel bars, and embodiments of the present invention are described in detail below with reference to fig. 1 to 9.
Specifically, referring to fig. 1, 3 and 4, the grabbing device for steel bars provided by the invention comprises a frame 110, a clamping mechanism 120 and a guiding mechanism 130. The clamping mechanism 120 comprises a first driving member 121 arranged on the frame 110, and a fixed clamping jaw 122 and a movable clamping jaw 123 arranged on the first driving member 121, wherein the first driving member 121 is suitable for driving the movable clamping jaw 123 to be close to or far from the fixed clamping jaw 122, and a clamping space 124 is formed between the fixed clamping jaw 122 and the movable clamping jaw 123; the guide mechanism 130 includes a second driving member 131 disposed on the frame 110, and a guide member 132 disposed on the second driving member 131, wherein the guide member 132 has a limiting cavity 134, and the second driving member 131 is adapted to drive the guide member 132 to approach the reinforcing steel bar 200 after the clamping space 124 clamps the reinforcing steel bar 200, so that the reinforcing steel bar 200 is limited in the limiting cavity 134.
Specifically, the present solution performs preliminary limiting on the steel bar 200 through the clamping space 124 between the fixed clamping jaw 122 and the movable clamping jaw 123, and drives the movable clamping jaw 123 to clamp the steel bar 200 through the first driving piece 121; in addition, this scheme carries out spacing again to reinforcing bar 200 through guiding mechanism 130's spacing cavity 134 for reinforcing bar 200 is firmly snatched by grabbing device 100, has avoided reinforcing bar 200 to skid, the skew problem after being snatched, makes follow-up production can go on smoothly.
Further, the longitudinal reinforcement bar 200 is a special-purpose reinforcement bar, and is mainly used for improving the longitudinal strength of the side surface of the reinforcement cage, and comprises a middle section and two side sections connected with the folding angles of the middle section respectively, wherein the clamping mechanism 120 and the guiding mechanism 130 are suitable for clamping and limiting the middle section of the longitudinal reinforcement bar.
It should be noted that, the present invention may be used to grip other types of steel bars 200 besides the longitudinal reinforcing bars, or to grip other rod-shaped, tubular, and beam-shaped materials, and the present invention enumerates the longitudinal reinforcing bars only to be beneficial to illustrate the present solution, but does not limit the application scope of the present invention, so the above-mentioned expanded content also falls within the protection scope of the present invention.
In addition, as shown in fig. 3, the guide 132 may be moved back and forth. Specifically, after the clamping mechanism 120 clamps the steel bar 200, the guide member 132 moves forward, so that the steel bar 200 is located in the limiting cavity 134, and plays a role in guiding; when the steel bar 200 is placed in the steel bar cage, the guide piece 132 moves backwards, so that the steel bar 200 is separated from the limiting cavity 134, and interference between the guide piece 132 and the steel bar cage is avoided.
Preferably, the width of the spacing cavity 134 is greater than the diameter of the rebar 200 and less than 1.5 times the diameter of the rebar 200. The width of the limiting cavity 134 can be slightly smaller than the diameter of the steel bar 200, and the steel bar 200 is limited in an interference fit manner, so that the limiting cavity 134 is preferably larger than the diameter of the steel bar 200 and smaller than 1.5 times of the diameter of the steel bar 200, and the limiting process is easier and smoother.
