[0035] An embodiment of the present application provides a ferrule centering device, which is used to center and position the ferrule before a robot grabs the ferrule to a rotary riveting device, so that the robot can smoothly put the ferrule on the end of the cage reinforcement at one time, and then the rotary riveting device can rivet the ferrule to the cage reinforcement in a subsequent process.

[0036] The structure of the ferrule centering device in the present application is described below. It is understandable that in other embodiments, the ferrule centering device in the present application is not limited to being used only for centering the ferrule to locate the center of the ferrule, but can also be used for centering any cylindrical workpiece, which is not limited here.

[0037] See also Figure 1 , Figure 1 The schematic diagram of the structure of the ferrule centering device 10 in one embodiment of the present application is shown. The ferrule centering device 10 provided in one embodiment of the present application comprises a conveying line body 100, a centering mechanism 200 and a height measuring mechanism 300, wherein the conveying line body 100 is used to convey the ferrule 50 along a first horizontal direction (the X direction shown in the figure); the centering mechanism 200 is connected to the conveying line body 100, and is used to center the ferrule 50 being transported on the conveying line body 100; the height measuring mechanism 300 is used to measure the height of the ferrule 50 before the ferrule 50 is centered by the centering mechanism 200, so as to determine whether the height dimension of the ferrule 50 is within a specified range, so as to avoid a large height error of the produced ferrule 50, resulting in position deviation during riveting in subsequent processes and causing unstable product quality.

[0038] Specifically, in one embodiment, the conveying line body 100 includes a bracket 110 and a conveying assembly 120 arranged above the bracket 110. The bracket 110 is used to be installed on the ground through an adjusting bolt 120 to play a supporting role. The adjusting bolt 120 can adjust the height of the bracket 110, thereby adjusting the overall installation height of the ferrule centering device 10.

[0039] The conveying assembly 120 includes a second driving source (not shown in the figure) and a plurality of conveying rollers 121 spaced apart along the first horizontal direction. Each conveying roller 121 can rotate around its own central axis. The second driving source is transmission-connected to any one of the conveying rollers 121. The second driving source can be a driving source such as a servo motor. Driven by the second driving source, the conveying roller 121 connected to the second driving source can rotate around its own central axis, thereby driving the hoop 50 to move forward along the first horizontal direction. While the hoop 50 moves forward along the first horizontal direction, it also drives the other conveying rollers 121 to rotate around their own central axes.

[0040] Preferably, on the basis of the above embodiment, any two adjacent conveying rollers 121 can also be connected to each other through a transmission chain or a synchronous belt. In this way, when one of the conveying rollers 121 rotates around its own central axis under the drive of the second driving source, it can simultaneously drive all other conveying rollers 121 to rotate around their own central axes, which can improve the reliability of transportation.

[0041] More preferably, the conveying assembly 120 further includes two mounting seats 122 arranged at intervals relative to each other in a second horizontal direction (the Y direction shown in the figure) perpendicular to the first horizontal direction, and the opposite ends of each conveying roller 121 are rotatably connected to a corresponding mounting seat 122, and at least two equal-height blocks 210 are respectively provided on the top of the centering mechanism 200 in the second horizontal direction, and each mounting seat 122 is overlapped on the equal-height block 210 located at a corresponding end of the centering mechanism 200. By providing the equal-height blocks 210, it can be ensured that the two mounting seats 122 can be located in the same horizontal plane, so that each conveying roller 121 can be arranged horizontally, and the hoop 50 is prevented from being offset when being conveyed on the conveying roller 121.

[0042] See also Figure 2 and Figure 3 In terms of the structure of the centering mechanism 200, the centering mechanism 200 includes two centering components 220 that are relatively spaced apart along a second horizontal direction. The two centering components 220 can be controllably moved closer to or farther away from each other along the second horizontal direction to center the ferrule 50 being transported on the conveyor line body 100.

[0043] More specifically, the centering assembly 220 is driven by the third driving source 230 and can be controlled to move. In one embodiment, the centering mechanism 200 further includes a support seat 240 and a transmission assembly 250. The support seat 240 is fixedly mounted on the bracket 110, the equal height block 210 is arranged on the support seat 240, and the mounting seat 122 of the conveying assembly 120 is overlapped on the equal height block 210. The third driving source 230 is fixedly mounted on the support seat 240, each centering assembly 220 is slidably arranged on the support seat 240 and penetrates the conveying assembly 120 in the vertical direction, specifically penetrates the gap formed by two adjacent conveying rollers 121, and each centering assembly 220 is also connected to the third driving source 230 through the transmission assembly 250.

[0044] like Figure 3 As shown, in one embodiment, the transmission assembly 250 includes a transmission rod 251 and two screw nuts 252, the transmission rod 251 is rotatably connected to the support seat 240 around its own central axis, and one end of the transmission rod 251 is connected to the third driving source 230 through transmission, the two screw nuts 252 are connected to the transmission rod 251 through transmission, and the two centering assemblies 220 are respectively connected to a corresponding screw nut 252. In the embodiment shown in the figure, the transmission rod 251 is connected to the third driving source 230 through synchronous belt transmission. Specifically, the output end of the third driving source 230 is equipped with a driving synchronous pulley 253, and one end of the transmission rod 251 is equipped with a passive synchronous pulley 254, and the two ends of the synchronous belt are respectively wound around the driving synchronous pulley 253 and the passive synchronous pulley 254. The third driving source 230 may also be a servo motor, etc. Under the drive of the third driving source 230, the driving rod 251 can rotate around its own central axis through the transmission of the active synchronous pulley 253, the synchronous belt and the passive synchronous pulley 254, thereby driving the two screw nuts 252 to move along the axial direction of the driving rod 251, and then driving the two centering components 220 to move. Of course, the driving rod 251 can also be directly connected to the output end of the third driving source 230, which is not limited here.

[0045] Further, in a more specific embodiment, see Figure 3 The transmission rod 251 includes a first transmission screw rod 251a and a second transmission screw rod 251b connected end to end. The thread rotation directions of the first transmission screw rod 251a and the second transmission screw rod 251b are opposite. One screw nut 252 is transmission-connected to the first transmission screw rod 251a, and the other screw nut 252 is transmission-connected to the second transmission screw rod 251b. The two centering components 220 are respectively connected to a corresponding screw nut 252, so that when the transmission rod 251 rotates around its own central axis, the two centering components 220 can be driven to move closer to or away from each other along the second horizontal direction.

[0046] It is understandable that the first transmission screw rod 251a and the second transmission screw rod 251b may be integrally connected or may be connected as shown in FIG. Figure 3 As shown in FIG. 2 , the two components are connected by a coupling 255 , which is not particularly limited here.

[0047] In the specific structure of the centering assembly 220, each centering assembly 220 includes a roller fixing plate 221 and at least two centering rollers 222. The roller fixing plate 221 is connected to a corresponding screw nut 252 in the transmission assembly 250, and the centering roller 222 is arranged on the roller fixing plate 221. In the embodiment shown in the figure, each centering assembly 220 includes two centering rollers 222, and the two centering rollers 222 are arranged at intervals along the first horizontal direction. Each centering roller 222 is vertically inserted into the gap formed by any two conveying rollers 121. All the centering rollers 222 in the two centering assemblies 220 jointly form a centering gap 201 with a variable size, so that the position of the hoop 50 can be automatically adjusted according to the diameter of the hoop 50 to achieve the centering of the hoop 50. In other embodiments, the number of centering rollers 222 in each centering assembly 220 is not limited, and may be more than two. All centering rollers 222 are arranged at intervals along the first horizontal direction, or the centering rollers 222 may be replaced by flat plates, etc., which is not limited here.

[0048] In order to detect whether there is a ferrule 50 in the centering gap 201 formed by the two centering components 220, the ferrule centering device 10 also includes a photoelectric device (not shown in the figure), which includes a transmitting part and a receiving part. The transmitting part and the receiving part are respectively arranged at opposite ends of the conveying line body 100 along the second horizontal direction. The transmitting part is used to transmit light, and the receiving part is used to receive light. The light is used to illuminate the ferrule 50. When the receiving part can receive the light emitted by the transmitting part, it indicates that there is no ferrule 50 in the centering gap 201. When the receiving part cannot receive the light emitted by the transmitting part, it indicates that there is a ferrule 50 in the centering gap 201, and the ferrule 50 blocks the light emitted by the transmitting part, so that the receiving part cannot receive the light.

[0049] like Figure 4As shown, in one embodiment, the height measuring mechanism 300 includes a mounting plate 310, a first driving source 320, a first pressing plate 330 and a measuring element 340, wherein the mounting plate 310 is fixedly mounted on one side of the bracket 110 of the conveyor line body 100, the first driving source 320 is fixedly mounted on the mounting plate 310, the first pressing plate 330 is connected to the first driving source 320, and the measuring element 340 is mounted on the mounting plate 310 and connected to the first pressing plate 330. The first driving source 320 may be a cylinder or a hydraulic cylinder controlled by a solenoid valve, etc., which is used to drive the first pressing plate 330 to rise and fall relative to the conveyor line body 100, and the measuring element 340 may be a displacement sensor, which is used to measure the height of the hoop 50 when the hoop 50 is centered by the centering mechanism 200 and the first pressing plate 330 presses the top of the hoop 50.

[0050] The specific measurement method is as follows: when the first driving source 320 drives the first pressing plate 330 to rise to an initial position, the measuring element 340 records the height M of the initial position. Then, the first driving source 320 drives the first pressing plate 330 to descend a certain distance until the first pressing plate 330 presses the top of the hoop 50. The measuring element 340 then records the height N of the first pressing plate 330. The height of the hoop 50 can be calculated by subtracting M from N.

[0051] When the measurement is completed, the hoop 50 is grabbed and raised by the robot arm, in order to avoid the hoop 50, the height measuring mechanism 300 also includes a fourth driving source 350, and the fourth driving source 350 is connected to the output end of the first driving source 320, and the first pressing plate 330 is connected to the output end of the fourth driving source 350. The first driving source 320 can drive the fourth driving source 350 and the first pressing plate 330 to rise and fall together in the vertical direction; and under the drive of the fourth driving source 350, the first pressing plate 330 can also rotate around an axis extending in the vertical direction, so as to avoid the hoop 50 when the robot arm grabs the hoop 50 and raises it.

[0052] In addition, when the height of the hoop 50 is measured by the height measuring mechanism 300, in order to fix the hoop 50 to prevent the hoop 50 from moving at will, the hoop 50 is fixed to the height measuring mechanism 300. Figure 1 and Figure 5 As shown, the ferrule centering device 10 also includes a pressing mechanism 400, which includes a fifth driving source 410 and a second pressing plate 420. The fifth driving source 410 is installed on the edge of the bracket 110 of the conveyor line body 100, and the second pressing plate 420 is connected to the output end of the fifth driving source 410. Driven by the fifth driving source 410, the second pressing plate 420 can be controlled to rise and fall in the vertical direction like the first pressing plate 330, and / or rotate around an axis extending in the vertical direction, so as to press the top of the ferrule 50 to prevent the ferrule 50 from moving at will when the height is measured, and also to avoid the ferrule 50 when the manipulator grabs the ferrule 50 and rises. It will not be repeated here.

[0053] Combination Figure 2 and Figure 3 ,as well as Figure 6 and Figure 7 As shown, the action flow of the ferrule centering device 10 provided by the present application is as follows:

[0054] When the hoop 50 needs to be centered and measured in height, the second driving source drives the conveying roller 121 to convey the hoop 50 to the centering gap 201 formed between the two centering components 220 along the first horizontal direction; then the second driving source is closed, and the third driving source 230 is turned on, and the driving transmission component 250 drives the two centering components 220 to approach each other along the second horizontal direction, so that the two centering components 220 adjust the positions of the hoop 50 to complete the centering of the hoop 50; finally, the fifth driving source 410 is started, and the second pressing plate 420 is used to press the top of the hoop 50, and then the third driving source 230 is driven, and the first pressing plate 330 is used to rise to an initial position and press the top of the hoop 50, and the height of the hoop 50 is measured according to the value recorded by the measuring element 340.

[0055] After the height measurement and centering of the ferrule 50 are completed, the above-mentioned driving sources drive the components to perform opposite actions, so that the robot can grab the ferrule 50 and move it to the riveting equipment for subsequent processes, which will not be repeated here.

[0056] It can be seen that the ferrule centering device provided by the present application, on the one hand, can automatically adjust the position of the ferrule according to the diameter of the ferrule by using a simple mechanical structure, and can center the ferrule without using a visual positioning device, so that when the manipulator grabs the ferrule, the ferrule can be smoothly put on the end of the cage reinforcement at one time, which not only improves the efficiency of pipe pile production, but also saves the cost of production. On the other hand, by setting up a height measuring mechanism, the ferrule centering device has the function of centering and the function of height measuring, making the ferrule centering device more comprehensive and convenient for users to use.

[0057] 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.

[0058] 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.
