Description

Technical Field

[0001] The present application relates to the technical field of concrete pipe pile production equipment, and particularly relates to a recognition device for identifying the position of bolts and a bolt disassembly device. Background Art

[0002] With the rapid development of China's economy, pipe piles are required for the foundation of railways, highways, bridge buildings, etc., and the demand for pipe piles has increased significantly. During the production process of pipe piles, a head plate and a tail plate are respectively installed at both ends of the pipe pile. After the pipe pile is cured and taken out of the curing pond, these head plates and tail plates need to be disassembled and recycled. The above-mentioned head plate is fixed to the end plate on the end face of the pipe pile by external hexagon bolts. Therefore, during the disassembly process, these external hexagon bolts need to be disassembled first.

[0003] Before disassembling the bolts, it is necessary to first identify the positions of the bolts so that the pneumatic wrench used to disassemble the bolts can accurately locate the positions of the bolts and accurately move to the positions where the bolts are located to clamp the heads of the bolts, so as to smoothly disassemble the bolts. Therefore, in the bolt disassembly device for the head and tail plates of pipe piles, the core technology is the automatic positioning of the positions of the bolts. However, currently, most of the bolt positioning methods basically use a vision camera to perform machine vision recognition on the positions where the bolts are located. Although the machine vision recognition method can accurately locate the positions of the bolts, the vision camera is usually expensive, and from the perspective of the production and manufacturing of the bolt disassembly device, the cost is too high. Utility Model Content

[0004] Based on this, in view of the problem of too high cost existing in the existing bolt disassembly device using machine vision positioning to locate the positions of bolts, it is necessary to provide a recognition device for identifying the positions of bolts and a bolt disassembly device including the recognition device that can solve the above problems.

[0005] According to one aspect of the present application, a recognition device for identifying the position of a bolt is provided, including:

[0006] A mounting seat;

[0007] A sensor, arranged on the mounting seat;

[0008] A connecting shaft, extending along a first horizontal direction, one end of the connecting shaft is connected to the mounting seat;

[0009] An induction collision block, spaced from the sensor in the vertical direction, the induction collision block has a first end and a second end oppositely arranged along a second horizontal direction perpendicular to the first horizontal direction, the first end is rotatably connected to the connecting shaft, and the second end is used for contacting the bolt head of the bolt;

[0010] When the second end abuts against the bolt head from bottom to top along the vertical direction, the second end can rotate around the central axis of the connecting shaft, so as to change the distance between the induction bump and the sensor. In response to the position change generated between the induction bump and the sensor, the sensor can identify the position of the bolt.

[0011] In one embodiment, the mounting seat includes a body, a first mounting portion and a second mounting portion. The first mounting portion and the second mounting portion are arranged at one side of the body at intervals along the vertical direction to jointly form a mounting groove. The first mounting portion or the second mounting portion is provided with a mounting hole communicating with the mounting groove. The sensor is inserted through the mounting hole, and the induction bump is partially received in the mounting groove.

[0012] In one embodiment, the second mounting portion is arranged above the first mounting portion at intervals. The mounting hole is opened on the second mounting portion. A first contact portion capable of floating up and down along the vertical direction is arranged in the mounting groove. The lower side of the induction bump is lapped on the first contact portion.

[0013] In one embodiment, the identification device further includes a first indexing pin. One end of the first indexing pin is fixedly connected to the first mounting portion, and the other end penetrates through the second mounting portion from bottom to top along the vertical direction and extends into the mounting groove. The first contact portion is located at the end of the first indexing pin extending into the mounting groove.

[0014] In one embodiment, a second contact portion capable of floating up and down along the vertical direction is further arranged in the mounting groove. The second contact portion abuts against the upper side of the induction bump.

[0015] In one embodiment, the identification device further includes a second indexing pin. One end of the second indexing pin is fixedly connected to the second mounting portion, and the other end penetrates through the second mounting portion from top to bottom along the vertical direction and extends into the mounting groove. The second contact portion is located at the end of the second indexing pin extending into the mounting groove.

[0016] In one embodiment, the induction bump is further slidably connected to the connecting shaft along the first horizontal direction, and the induction bump is provided with a through hole penetrating through opposite sides of itself. When the induction bump touches the end face of the bolt head, the induction bump can retreat in a direction away from the bolt along the first horizontal direction, so that the through hole is aligned with the sensor.

[0017] In one embodiment, an elastic member is sleeved on the connecting shaft. One end of the elastic member is connected to the mounting base, and the other end is connected to the first end of the sensing striker. The elastic member is configured to provide an elastic force for resetting the sensing striker along the first horizontal direction when the sensing striker abuts against the end face of the bolt head.

[0018] In one embodiment, the identification device further includes a first driving member and a second driving member. The mounting base is connected to the first driving member, and the first driving member is connected to the output end of the second driving member. The first driving member is used to drive the mounting base, the sensor, the connecting shaft, and the sensing striker to move together along the first horizontal direction, and the second driving member is used to drive the first driving member, the mounting base, the sensor, the connecting shaft, and the sensing striker to move together along the vertical direction or along a circumferential direction.

[0019] According to another aspect of the present application, a bolt disassembling device is provided, including:

[0020] The identification device and the disassembling device as described in any of the above solutions. The disassembling device has a pneumatic wrench, and the pneumatic wrench is used to position to the position where the bolt is located according to the bolt position identified by the identification device, so as to disassemble the bolt from the workpiece.

[0021] The above-mentioned identification device for identifying the bolt position and the bolt disassembling device including the identification device are provided with a sensor and a connecting shaft on the mounting base, and the first end of the sensing striker is rotatably connected to the connecting shaft, so that when the second end of the sensing striker opposite to the first end abuts against the bolt head of the bolt from bottom to top, the second end of the sensing striker can rotate around the central axis of the connecting shaft. At this time, the position between the sensing striker and the sensor will change. In response to the position change generated between the sensing striker and the sensor, the sensor can identify the position where the bolt is located. Therefore, compared with the traditional machine vision recognition method, it uses a simple mechanical recognition method for recognition, so the structure is simple, the operation is convenient, the manufacturing cost and cost are relatively low, and the production and manufacturing cost of the bolt disassembling device is effectively saved.

[0036] An embodiment of this application provides an identification device for identifying the position of a bolt and a bolt disassembly device. The bolt disassembly device includes the above-mentioned identification device. The bolt disassembly device is used to automatically disassemble the bolts on a workpiece, so as to reduce the labor intensity and improve the disassembly efficiency. The identification device is used to accurately locate the bolt with a pneumatic wrench used for disassembling the bolt before disassembling the screw and can accurately move to the position where the bolt is located, so that the bolt can be smoothly disassembled from the workpiece.

[0037] Taking the workpiece as a pipe pile as an example, and taking the identification device for identifying the position of the bolts connecting the pipe pile and the head or tail plate of the pipe pile (hereinafter referred to as the head and tail plate) as an example, and taking the bolt disassembly device for disassembling the bolts connecting the pipe pile and the head or tail plate of the pipe pile (hereinafter referred to as the head and tail plate) as an example, the structure of the bolt automatic disassembly device and the structure of the identification device in the present application will be described. It can be understood that in other embodiments, the bolt automatic disassembly device of the present application is not limited to only being able to disassemble the bolts connecting the pipe pile and the head and tail plates of the pipe pile, and can also be used to disassemble the bolts on any workpiece, and the identification device for identifying the position of the bolts in the present application is not limited to only being able to identify the position of the bolts connecting the pipe pile and the head and tail plates of the pipe pile, and can also be used to identify the position of the bolts on any workpiece, which is not limited herein.

[0038] The bolt disassembly device provided by an embodiment of the present application includes Figure 1 and Figure 2 the identification device 10 and the disassembly device (not shown in the figure) as shown. As described above, the identification device 10 is used to identify the position of the bolts connecting the pipe pile and the head and tail plates. The disassembly device has a pneumatic wrench, which is used to locate to the position where the bolts are located according to the bolt positions identified by the identification device 10 to disassemble the bolts from the pipe pile.

[0039] Referring to Figure 1 and Figure 2 , the identification device 10 provided by an embodiment of the present application includes a mounting base 100, a sensor 200, a connecting shaft 300, and an induction bumper 400. The sensor 200 is arranged on the mounting base 100. The connecting shaft 300 extends along the first horizontal direction (i.e., the X direction shown in the figure). One end of the connecting shaft 300 is connected to the mounting base 100. The induction bumper 400 is spaced from the sensor 200 in the vertical direction (i.e., the Z direction shown in the figure). The induction bumper 400 has a first end 401 and a second end 402 oppositely arranged along the second horizontal direction perpendicular to the first horizontal direction (i.e., the Y direction shown in the figure). The first end 401 is rotatably connected to the connecting shaft 300. The second end 402 is used to contact the bolt head 20 of the bolt. When the second end 402 abuts against the bolt head 20 from bottom to top in the vertical direction, the second end 402 can rotate around the central axis of the connecting shaft 300, so that the distance between the induction bumper 400 and the sensor 200 changes. Specifically, the distance between the part of the induction device close to the first end 401 and the sensor 200 changes. In response to the position change generated between the induction bumper 400 and the sensor 200, the sensor 200 can generate a signal and identify the position of the bolt.

[0040] It can be understood that the change in the distance between the part of the induction bump 400 close to the first end 401 and the sensor 200 can be an increase or a decrease. In the embodiment shown in the figure, the sensor 200 is installed on the upper side of the mounting base 100 in the vertical direction. Therefore, as Figures 2 to 4 shown, when the second end 402 of the induction bump 400 abuts against the bolt head 20 from bottom to top in the vertical direction, as the induction bump 400 rotates around the central axis of the connecting shaft 300, the distance between the part of the induction bump 400 close to the first end 401 and the sensor 200 will decrease, so that the sensor 200 can generate a signal and identify the position of the bolt. Similarly, when the sensor 200 is installed on the lower side of the mounting base 100 in the vertical direction, as the induction bump 400 rotates around the central axis of the connecting shaft 300, the distance between the part of the induction bump 400 close to the first end 401 and the sensor 200 will increase, and the sensor 200 can also generate a signal and identify the position of the bolt, which will not be elaborated here.

[0041] Specifically, please continue to refer to Figure 1 and Figure 2 , in the structure of the mounting base 100, the mounting base 100 includes a body 110, a first mounting portion 120 and a second mounting portion 130. The first mounting portion 120 and the second mounting portion 130 are arranged at intervals in the vertical direction on one side of the body 110 to jointly form a mounting groove 100a. As shown in the embodiment in the figure, the first mounting portion 120 is located below the second mounting portion 130 at intervals in the vertical direction. The second mounting portion 130 is provided with a mounting hole communicating with the mounting groove 100a, and the sensor 200 is inserted through the mounting hole, so that the sensor 200 is installed on the upper side of the mounting base 100, and part of the induction bump 400 is accommodated in the mounting groove 100a. Of course, the mounting hole can also be opened on the first mounting portion 120, so that the sensor 200 is installed on the lower side of the mounting base 100.

[0042] Preferably, in order to prevent the induction bump 400 from rotating randomly around the central axis of the connecting shaft 300 when it does not touch the bolt head 20 of the bolt under a very small force (such as the influence of environmental wind force), a first contact portion 501 that can float up and down in the vertical direction is provided in the mounting groove 100a, and the lower side of the induction bump 400 is lapped on the first contact portion 501. In this way, when the induction bump 400 does not touch the bolt head 20 of the bolt, since the lower side of the induction bump 400 is lapped on the first contact portion 501 in the vertical direction, even if a very small force is applied to the upper side of the second end 402 of the induction bump 400, the second end 402 of the induction bump 400 will not rotate around the central axis of the connecting shaft 300, so that the situation of misidentification will not occur.

[0043] Preferably, in order to prevent the lower side of the second end 402 of the sensing block 400 from rotating about the central axis of the connecting shaft 300 even when a very small force is applied, a second contact portion 601 that can float up and down in the vertical direction is further provided in the installation groove 100a. The second contact portion 601 abuts against the upper side of the sensing block 400. In this way, whether it is the upper side or the lower side of the second end 402 of the sensing block 400, even when a very small force is applied, the second end 402 of the sensing block 400 will not rotate about the central axis of the connecting shaft 300. Only when the sensing block 400 abuts against the bolt head 20 and the sensing block 400 is subjected to a large force, the second end 402 of the sensing block 400 will push the first contact portion 501 or the second contact portion 601 to float up and down. Only at this time will the second end 402 of the sensing block 400 rotate about the central axis of the connecting shaft 300, causing the distance between the portion of the sensing block 400 close to the first end 401 and the sensor 200 to change. Therefore, the accuracy of recognition can be better guaranteed.

[0044] Exemplarily, in the recognition device 10 provided in the present application, a first indexing pin 500 and a second indexing pin 600 are provided to respectively form a first contact portion 501 and a second contact portion 601 in the installation groove 100a. One end of the first indexing pin 500 is fixedly connected to the first installation portion 120, and the other end passes through the second installation portion 130 from bottom to top in the vertical direction and extends into the installation groove 100a. The first contact portion 501 is located at the end of the first indexing pin 500 extending into the installation groove 100a. One end of the second indexing pin 600 is fixedly connected to the second installation portion 130, and the other end passes through the second installation portion 130 from top to bottom in the vertical direction and extends into the installation groove 100a. The second contact portion 601 is located at the end of the second indexing pin 600 extending into the installation groove 100a.

[0045] In other embodiments, it is not limited to setting the first indexing pin 500 and the second indexing pin 600 to respectively form the first contact portion 501 and the second contact portion 601. Elastic elements can also be provided on the bottom wall and the top wall of the installation groove 100a respectively, and the first contact portion 501 and the second contact portion 601 are respectively connected to the corresponding elastic elements to realize the up and down floating of the first contact portion 501 and the second contact portion 601 in the vertical direction, which is not limited herein.

[0046] It should be noted that when identifying the position of the bolt, since the position of the bolt is unknown, it is not necessarily guaranteed that the sensing block 400 can abut against the bottom of the bolt head 20 from bottom to top every time. In some cases, for example Figure 5As shown, the induction bumper 400 may touch the end face of the bolt head 20. At this time, if the identification device 10 is moved upward from the bottom, the induction bumper 400 will never be able to abut against the bolt head 20 of the bolt. Therefore, the second end 402 of the induction bumper 400 cannot rotate around the central axis of the connecting shaft 300, and the distance between the part of the induction bumper 400 near the first end 401 and the sensor 200 will not change. Therefore, the position of the bolt cannot be recognized.

[0047] To solve this problem, in an improved embodiment, in combination with Figure 5 and Figure 6 As shown, the induction bumper 400 is slidably connected to the connecting shaft 300 in the first horizontal direction, and the induction bumper 400 is provided with a through hole 403 penetrating through its opposite sides. When the induction bumper 400 touches the end face of the bolt head 20, the induction bumper 400 can retreat in the first horizontal direction away from the bolt, so that the through hole 403 is aligned with the sensor 200. When the through hole 403 is not aligned with the sensor 200, the sensor 200 can sense the induction bumper 400, and when the through hole 403 is aligned with the sensor 200, the sensor 200 cannot sense the induction bumper 400. Thus, based on the change of the signal sensed by the sensor 200 from having to not having, it is determined whether the induction bumper 400 touches the end face of the bolt head 20.

[0048] Furthermore, when the induction bumper 400 touches the end of the bolt head 20 and retreats in the first horizontal direction away from the bolt, in order to enable the induction bumper 400 to automatically reset after separating from the bolt head 20, an elastic member 700 such as a spring is sleeved on the connecting shaft 300. One end of the elastic member 700 is connected to the mounting seat 100, and the other end is connected to the first end 401 of the induction bumper 400. The elastic member 700 is configured to provide an elastic force for resetting the induction bumper 400 in the first horizontal direction when the induction bumper 400 abuts against the end face of the bolt head 20. After the mounting seat 100 and the induction bumper 400 continue to move their positions together by automatically resetting the induction bumper 400, the second end 402 of the induction bumper 400 can identify the positions of other bolts.

[0049] It can be understood that the way to move the induction block 400 can be to manually move the mounting base 100 to change the position of the induction block 400, or to drive the mounting base 100 to move through a driving source such as a cylinder to change the position of the induction block 400. Referring to the figure, in the embodiment shown in the figure, the identification device 10 further includes a first driving member 800. The mounting base 100 is connected to the output end of the first driving member 800. The first driving member 800 is used to drive the mounting base 100, the sensor 200, the connecting shaft 300 and the induction block 400 to move together along the first horizontal direction to approach or move away from the pipe pile. Preferably, the identification device 10 further includes a second driving member. The output end of the second driving member is connected to the first driving member 800. The second driving member is used to drive the first driving member 800, the mounting base 100, the sensor 200, the connecting shaft 300 and the induction block 400 to move together along the vertical direction or along a circumferential direction. That is, when the bolts on the workpiece are arranged in the vertical direction, through the driving of the second driving member, the induction block 400 can sequentially identify the positions of each bolt along the vertical direction. When the bolts on the workpiece are arranged in the circumferential direction (for example, the bolts connecting the pipe pile and the head and tail plates on the pipe pile), through the driving of the second driving member, the induction block 400 can sequentially identify the positions of each bolt along the circumferential direction.

[0050] When using the identification device 10 for identifying the position of bolts provided in the present application to identify the position of bolts, the operation steps are as follows:

[0051] In the first case, as Figure 3 and Figure 4 shown, when the first driving member 800 drives the mounting base 100 to extend in the direction approaching the workpiece, the elastic member 700 is in a normal state and is not compressed or stretched. At this time, the second driving member will drive the first driving member 800, the mounting base 100, the sensor 200, the connecting shaft 300 and the induction block 400 to move together as a whole along the vertical direction or the circumferential direction until the second end 402 of the induction block 400 contacts the bottom side of the bolt head 20 from bottom to top. At this time, the second end 402 of the induction block 400 will be subjected to a large force and rotate around the axis of the connecting shaft 300, causing the distance between the part of the induction block 400 close to the first end 401 and the sensor 200 to change, so as to enable the sensor 200 to sense the signal of identifying the bolt position and send the signal to the disassembly device, so that the pneumatic wrench of the disassembly device can accurately locate the position of the bolt and move to the position of the bolt to clamp and disassemble the bolt.

[0052] In the second case, as Figure 5 and Figure 6As shown, after the first driving member 800 drives the mounting base 100 to extend in the first horizontal direction towards the workpiece, if the sensing block 400 contacts the end face of the bolt head 20, the sensing block 400 will retract in the first horizontal direction away from the bolt, and the through hole 403 formed in the sensing block 400 will be aligned with the sensor 200. At this time, the signal of the sensing block 400 sensed by the sensor 200 changes from having to not having, indicating that the position of the bolt is not correctly recognized. At the same time, the elastic member 700 will be compressed. After the sensing block 400 is separated from the bolt head 20, the sensing block 400 will reset under the action of the elastic force provided by the elastic member 700. At this time, the second driving member will drive the first driving member 800, the mounting base 100, the sensor 200, the connecting shaft 300 and the sensing block 400 to move together in the vertical direction or the circumferential direction, start to recognize from the next bolt again, and then repeat the steps of the first case.

[0053] It can be seen that the identification device for identifying the position of the bolt and the bolt disassembly device including the identification device provided by the present application adopt a simple mechanical identification method for identification. Therefore, compared with the traditional machine vision identification method, the structure is simple, the operation is convenient, the manufacturing cost and the cost are relatively low, and the production and manufacturing cost of the bolt disassembly device is effectively saved.

[0054] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, 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, it should be considered as the scope described in this specification.

[0055] The above-described embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application should be subject to the appended claims.
