For example, railways, highways, bridges, etc. all need pipe piles to lay the foundation.

[0003] Specifically, the pipe pile is composed of concrete and cage reinforcement, and the cage reinforcement is composed of various types of steel bars such as round steel bars, straight steel bars, spiral steel bars, etc. After the cage reinforcement is roll-welded by the roll welding machine, the cage reinforcement enters the next riveting process. Before riveting, the hoop needs to be loaded to the station of the rotary riveting equipment so that the hoop can be put on the end of the cage reinforcement by the rotary riveting equipment in the subsequent process, and the hoop is riveted to the cage reinforcement. However, in the prior art, the hoop is usually loaded manually, but the hoop is usually welded from a 3mm thick sheet metal roll, and its outer surface is relatively sharp.

[0031] An embodiment of the present application provides a ferrule inner support clamp and a ferrule feeding device, wherein the ferrule feeding device includes a ferrule inner support clamp, the ferrule inner support clamp is used to position and fix the ferrule on the ferrule feeding device, and the ferrule feeding device is used to transfer the ferrule to a specified position to complete automatic loading of the ferrule.

[0032] The structures of the ferrule inner support fixture and the ferrule feeding device in the present application are described below. It is understandable that in other embodiments, the ferrule inner support fixture of the present application is not limited to being used only for positioning and fixing the ferrule, but can also be used to position and fix any cylindrical workpiece; the ferrule inner support fixture of the present application is not limited to being used only for feeding the ferrule, but can also be used to feed any cylindrical workpiece, which is not limited here.

[0033] A ferrule feeding device provided in one embodiment of the present application comprises a robotic arm and a ferrule inner support clamp as shown in FIG1 , wherein the ferrule inner support clamp is connected to the robotic arm, the ferrule inner support clamp is used to clamp the ferrule, and the robotic arm is used to transfer the ferrule to a designated position when the ferrule inner support clamp clamps the ferrule.

[0034] Referring to FIG. 1 , a sleeve inner support fixture 10 provided in one embodiment of the present application includes a mounting seat 100, a driving source 200 and a plurality of inner support components 300. The mounting seat 100 has a plurality of mounting portions 111 spaced apart in a circumferential direction defined by a central axis 50, and a plurality of inner support components 300 are slidably disposed on a corresponding mounting portion 111 on the mounting seat 100 at intervals around the central axis 50; the driving source 200 is also disposed on the mounting seat 100 and is connected to all the inner support components 300 through a transmission component 400, which is used to drive the transmission component 400 to drive all the inner support components 300 to slide synchronously on the corresponding mounting portion 111 along the radial direction defined by the central axis 50, so that all the inner support components 300 can be as Figure 2 As shown in FIG. 5 , the inner surface of the sleeve 60 is supported by the inner surface of the sleeve 60, or as shown in FIG. Figure 3 As shown in the figure, the inner support components 300 gather in the direction close to the central axis 50 to loosen the hoop 60. When all the inner support components 300 are spread out, all the inner support components 300 can clamp the hoop 60 so that the hoop 60 is fixed on the hoop inner support fixture 10. It can be understood that the driving source 200 can be any device that can provide power, such as a servo motor, and is not limited here.

[0035] Specifically, in one embodiment, as shown in FIG. 1 , the mounting seat 100 includes a first mounting plate 110 and a second mounting plate 120 which are spaced apart, wherein the second mounting plate 120 is fixedly connected to the end of the robot arm, the driving source 200 is disposed on the second mounting plate 120, the second mounting plate 120 is spaced apart from the first mounting plate 110, the first mounting plate 110 has a mounting portion 111, each mounting portion 111 extends along a radial direction defined by the central axis 50, and each inner support assembly 300 is slidably mounted on the corresponding mounting portion 111. In a preferred embodiment, a slide rail 130 is provided on each mounting portion 111, a slider 140 is slidably disposed on the slide rail 130, and each inner support assembly 300 is mounted on the corresponding slider 140, so that each inner support assembly 300 can only move along the above-mentioned radial direction under the guidance of the slide rail 130.

[0036] More preferably, the first mounting plate 110 and the second mounting plate 120 are interconnected by an elastic element 150 (such as a spring). The purpose of such a setting is that due to the deviation in the height dimension of the ferrule 60, the first mounting plate 110 and the second mounting plate 120 are interconnected by providing the elastic element 150, so that no matter what the height dimension of the ferrule 60 is, when the robot arm loads the ferrule 60 to a specified position (for example, when inserting it into a certain installation position), the elastic element 150 can produce a recoverable deformation to provide a buffer, so that the ferrule 60 can be loaded to a specified depth in the installation position, thereby avoiding the situation where the ferrule 60 is not loaded into place.

[0037] Please continue to refer to Figure 1. In one embodiment, the transmission assembly 400 includes a rotating shaft 410 (not shown in the figure), a rotating plate 420 and a plurality of connecting rods 430, wherein one end of the rotating shaft 410 is connected to the output end of the driving source 200, and the other end is passed through the first mounting plate 110 of the mounting base 100 and connected to the rotating plate 420, and one end of each connecting rod 430 is rotatably connected to the rotating plate 420, and the other end is rotatably connected to a corresponding inner support assembly 300.

[0038] In this way, driven by the driving source 200, the rotating shaft 410 and the rotating plate 420 can rotate together around the central axis 50. In response to the rotation of the rotating plate 420, one end of the connecting rod 430 can rotate relative to the rotating plate 420, and the other end can drive the inner support assembly 300 to move along the radial direction defined by the central axis 50.

[0039] Preferably, as shown in Figures 1 to Figure 3 As shown, each connecting rod 430 is in an arc shape. When all the inner support components 300 gather toward the direction close to the central axis 50, the arc opening of each connecting rod 430 faces the central axis 50, so that interference between the connecting rods 430 and the rotating rods can be avoided when the connecting rods 430 rotate.

[0040] Also preferably, in order to enable the rotating shaft 410 to smoothly rotate around its own central axis 50, in combination with FIG. 1 and Figure 4 As shown, a bearing seat 160 is fixedly mounted on the mounting seat 100, and a bearing 170 is arranged in the bearing seat 160. The outer circumference of the bearing 170 is attached to the inner circumference of the bearing seat 160, and the inner circumference of the bearing 170 is sleeved on the rotating shaft 410. Specifically, the bearing seat 160 is mounted on the side of the first mounting plate 110 facing the second mounting plate 120, and the bearing 170 is preferably a deep groove ball bearing 170. The advantage of using the deep groove ball bearing 170 is that the deep groove ball bearing 170 has a small friction resistance, a high rotation speed, and excellent axial and radial load-bearing capacity. At the same time, a retaining spring 180 is also installed at the opposite ends of the bearing 170 in the bearing seat 160, and each retaining spring 180 is sleeved on the rotating shaft 410, which is used to limit the bearing 170 and prevent the bearing 170 from moving along the axial direction of the rotating shaft 410.

[0041] It should be noted that the transmission assembly 400 is not limited to the structure described in the above embodiment, and the driving source 200 may also be connected to a telescopic rod, and the telescopic rod is connected to each inner support assembly 300 through two mutually cooperating wedge blocks, each wedge block has an inclined surface that cooperates with another wedge block. When the driving source 200 drives the telescopic rod to reciprocate in a straight line direction, it can also drive the inner support assembly 300 to reciprocate in the radial direction to diffuse or gather.

[0042] In the structure of the inner support component 300, as shown in Figure 1, the inner support component 300 includes an inner support member 310 and a buffer pad 320. The inner support member 310 is slidably mounted on the mounting portion 111 of the first mounting plate 110. The buffer pad 320 is arranged on the inner support member 310, and its material is made of elastic material, such as rubber, polyurethane, etc. The purpose of arranging the buffer pad 320 is to avoid the support portion 312 from being in hard contact with the inner circumference of the sleeve 60, which causes the sleeve 60 to deform. When the inner support component 300 abuts against the inner circumference of the sleeve 60, the buffer pad 320 can undergo a recoverable deformation, thereby preventing the inner support component 300 from being in hard contact with the inner circumference of the sleeve 60, which causes the sleeve 60 to deform.

[0043] Specifically, the inner support member 310 includes a connecting portion 311 and a supporting portion 312 which are perpendicularly arranged to each other. The connecting portion 311 is mounted on the slider 140 so that the connecting portion 311 is slidably connected to the mounting portion 111 of the mounting seat 100. The buffer pad 320 is arranged on the side of the supporting portion 312 which is opposite to the central axis 50. It can be understood that the structure of the inner support member 310 is not limited to the structure described in the above embodiment, and can also be a structure of any shape, as long as it can support the inner circumference of the hoop 60 when all the inner support components 300 are spread, and is not limited here.

[0044] In addition, in order to limit the movement range of the inner support assembly 300, that is, to prevent the inner support assembly 300 from continuing to gather when all the inner support assemblies 300 gather and move a certain distance, a sensing element 190 is provided on the second mounting plate 120 of the mounting base 100, and a proximity switch 330 corresponding to the sensing element 190 is provided on the inner support assembly 300. The sensing element 190 is configured to contact the proximity switch 330. When the sensing element 190 contacts the proximity switch 330, the inner support assembly 300 cannot continue to move in the direction close to the central axis 50, thereby preventing the inner support assembly 300 from continuing to gather.

[0045] It can be seen that when the ferrule feeding device provided in the present application is used to feed the ferrule, the ferrule is fixed by the ferrule internal support clamp, so that the robotic arm can transfer the ferrule to the designated position for loading instead of manual labor, thereby improving the loading efficiency and eliminating the safety hazard caused by the ferrule scratching the arm during loading.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
