Description

Technical Field

[0001] The utility model relates to the technical field of pipe piles in the construction industry, and in particular to an adaptive sleeve clamping claw device. Background Art

[0002] Pipe piles are a product used in the construction industry and are often used in soft foundation treatment. Due to the soil squeezing effect, pipe piles can compact the soft soil layer, thereby improving the bearing capacity of the soft soil foundation.

[0003] Pipe piles are made of concrete and cage reinforcement, which is composed of various types of steel bars, such as round bars, straight bars, and spiral bars. After the cage reinforcement is roll-welded by a roll welder, it enters the next riveting process. Currently, the cage reinforcement is manually placed on both ends of the cage reinforcement. The cage reinforcement is then transported by transplanting equipment to a rotary riveting machine for riveting at both ends. Since the ferrule is generally welded from a 3mm thick sheet metal coil, the outer surface is sharp and manual loading can easily scratch the arm, posing a certain safety hazard. In addition, the cage reinforcement is long, and in order to improve production efficiency, it is often necessary to arrange for two workers to simultaneously apply the ferrule at both ends, resulting in a waste of human resources.

[0020] In order to more clearly describe the technical content of the present invention, it is further described below in conjunction with specific embodiments.

[0021] like Figures 1 to 3 The figure shows an embodiment of the adaptive ferrule clamping device of the present invention. The clamping device includes a shaft assembly 1 and a clamping assembly 2. The shaft assembly 1 includes a shaft 3 and a drive mechanism. The drive mechanism is used to drive the shaft 3 to rotate around the rotation axis. The clamping assembly 2 includes three clamping units evenly distributed along the circumference of the shaft 3. Each clamping unit includes an inner support rod 4, a guide rail 5, and a sliding portion having a clamping plate 6. The clamping plate 6 is used to be sleeved in the ferrule. The sliding portion is movably provided on the guide rail 5. The guide rail 5 is radially arranged along the shaft 2. The sliding portion extends outward, and the sliding portion is connected to the rotating shaft 3 via the inner support link 4, so that when the positive rotational motion of the rotating shaft 3 is converted by the inner support link 4 into the radial outward movement of the sliding portion along the guide rail 5 toward the rotating shaft 3, the clamping plates 6 clamp the inner wall of the ferrule to achieve the ferrule material removal; and when the reverse rotational motion of the rotating shaft 3 is converted by the inner support link 4 into the radial inward movement of the sliding portion along the guide rail 5 toward the rotating shaft 3, the clamping plates 6 release the inner wall of the ferrule to achieve the ferrule material discharge. The inner support links 4 are distributed along the circumference of the rotating shaft 3 and are arc-shaped.

[0022] Therefore, the clamping jaw device of the present invention can clamp and release ferrules of different specifications through three clamping jaw assemblies evenly distributed along the circumference, so as to clamp ferrules of different specifications and improve production efficiency.

[0023] like Figure 2 As shown, the sliding part includes a clamping jaw fixing plate 7 and a sliding block 8, the clamping jaw plate 6 is vertically mounted on the clamping jaw fixing plate 7, the clamping jaw fixing plate 7 is mounted on the sliding block 8, and the inner support connecting rod 4 drives the clamping jaw plate 6, the clamping jaw fixing plate 7 and the sliding block 8 to move simultaneously, thereby precisely controlling and adapting to various specifications of ferrules.

[0024] like Figure 2As shown, the clamping plate is provided with a buffer mechanism, which includes a buffer plate 9, an elastic member 10, a guide shaft 11 and a buffer bearing 12. The outer side surface of the buffer plate 9 cooperates with the inner wall of the hoop, and the buffer bearing 12 is transversely arranged on the clamping plate 6. One end of the guide shaft 11 is connected to the inner side surface of the buffer plate 9, and the other end of the guide shaft 11 is passed through the buffer bearing 12. One end of the elastic member 10 is connected to the buffer plate 9, and the other end of the elastic member 10 is connected to the clamping plate 6 to generate an elastic force between the buffer plate 9 and the clamping plate 9. In this embodiment, the elastic member 10 is a spring, and the spring is sleeved outside the guide shaft 11. The buffer mechanism can effectively buffer and adapt to the deformation of the hoop to a certain extent. The buffer plate 9 can use a polyurethane buffer plate.

[0025] In the embodiments provided by the present invention, Figure 2 As shown, two sets of guide shafts and buffer bearings are used. The two guide shafts can be connected with a connecting rod, which can effectively ensure that the axes of the two guide shafts are parallel. There is no need for repeated debugging to prevent them from getting stuck during movement. Use 201 to connect both ends with limits and just install them.

[0026] like Figure 1 As shown, the gripper unit includes a laser sensor 15. When the gripper device of the present invention is mounted on a manipulator, the laser sensor 15 can be used to detect the position of the material and grasp the material.

[0027] like Figure 3 As shown, the rotating shaft 3 is mounted on the mounting seat via a bearing seat 13, in which a retaining spring and a bearing are disposed. In this embodiment, the driving mechanism may be composed of a servo motor 14, a worm gear reducer, etc. The servo motor 14 drives the rotating shaft 3 to rotate, which in turn drives the internal support links 4 to move, causing the sliding portion to move along the guide rail 5.

[0028] When the adaptive ferrule clamp device of the present invention performs a material picking operation, the servo motor rotates clockwise, driving the rotating shaft to rotate, and the sliding part is pulled radially outward by the inner support connecting rod to support the inner wall of the ferrule; when performing a material discharging operation, the principle is the same as the material picking operation. After the robotic arm places the material on the production station, the servo motor rotates counterclockwise to loosen the ferrule.

[0029] In this specification, the present invention has been described with reference to specific embodiments thereof. However, it is apparent that various modifications and variations may be made without departing from the spirit and scope of the present invention. Accordingly, the specification and drawings are to be regarded as illustrative rather than restrictive.
