DETAILED DESCRIPTION

[0023] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0024] The disclosure below provides many different embodiments or examples to realize the different structures of the present application. In order to simplify the disclosure of the present application, the parts and settings of specific examples are described below. Of course, they are only examples, and the purpose is not to limit the present application. In addition, the present application can repeat reference numbers and / or reference letters in different examples, and this repetition is for the purpose of simplification and clarity, which itself does not indicate the relationship between the various embodiments and / or settings discussed.

[0025] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0026] See also Figure 1 and Figure 3 The embodiment of the present application provides a connecting arm 100, which is used to connect with the rotating shaft 410 of the product 400. The rotating shaft 410 is provided with a connecting hole 411. The connecting arm 100 includes a main body 10 and a plurality of connecting components 20. The main body 10 is, for example, in the shape of a plate, a strip or other shapes. The main body 10 can be straight or bent. The main body 10 is used to connect with an external detection device. The external detection device performs torque detection on the product 400 through the main body 10. Therefore, the shape and structure of the main body 10 can be connected by the external detection device.

[0027] Specifically, see Figure 1 and Figure 2 , a connecting end 11 is provided at one end of the main body 10, and a plurality of mounting holes 111 corresponding to the positions of the connecting holes 411 are provided at the connecting end 11, and the mounting hole 111 includes a first accommodating section 112, a spacing section 113 and a second accommodating section 114 connected in sequence, and the diameter of the spacing section 113 is smaller than the diameter of the first accommodating section 112 and the second accommodating section 114; and a plurality of connecting components 20, each of which includes a connecting member 21, and the connecting member 21 is arranged in the mounting hole 111, and the connecting member 21 includes a driving portion 211, a sliding portion 212 and a connecting portion 213 connected in sequence, see Figure 3 The driving part 211 is used to be driven by an external driving mechanism, and then the connecting part 213 is driven to connect with the rotating shaft 410 through the sliding part 212. The connecting part 21 is, for example, a bolt or other part that can connect the connecting part 213 with the rotating shaft 410 of the product 400. The external driving mechanism is, for example, a screwdriver, a hexagonal wrench, an electric screwdriver, etc. Among them, the diameter of the sliding part 212 is smaller than the diameter of the spacing section 113, so that the sliding part 212 can slide along the spacing section 113, and the diameter of the connecting part 213 is larger than the diameter of the spacing section 113 and smaller than the diameter of the second accommodating section 114, so that the sliding part 212 can be accommodated by the second accommodating section 114 and blocked by the spacing section 113. In this way, the connecting part 213 of the connecting part 21 can be blocked in the second accommodating section 114 through the spacing section 113 of the mounting hole 111, so that the connecting part 21 will not fall off from the mounting hole 111, eliminating the step of the operator taking the connecting part 21, and improving efficiency. It can be understood that there can be multiple mounting holes 111, such as two, four or six, and there can be multiple groups of connecting components 20, such as two, four or six. The number of connecting components 20 is selected based on the standard of being able to stably connect the connecting end 11 with the rotating shaft 410 of the product 400. For example, two groups are set. Under the premise of stable connection, the installation and disassembly time can be reduced and the efficiency can be improved.

[0028] The use process of the connecting arm 100 provided in some embodiments is roughly as follows: first, the connecting end 11 of the main body 10 is aligned with the rotating shaft 410 of the product 400, and then the connecting member 21 is connected to the rotating shaft 410 of the product 400 through an external driving mechanism, thereby completing the connection between the product 400 and the connecting arm 100. In this way, the connection operation can be performed by only aligning the connecting arm 100 with the product 400, without the need to take the connecting member 21, thereby reducing the operation steps and improving the operation efficiency. When disassembly is required, the connecting member 21 can be separated from the rotating shaft 410 of the product 400 through an external driving mechanism. In this way, the product 400 can be separated by loosening the connecting member 21 from the product 400, without the need to take out the connecting member 21, thereby further reducing the operation steps and improving the efficiency.

[0029] The connecting arm 100 provided in the embodiment of the present application is provided with a main body 10 and a connecting component 20, and the main body 10 can be connected to the product 400 through the connecting component 20. The connecting end 11 is provided with a plurality of mounting holes 111, and the connecting member 21 of the connecting component 20 is arranged in the mounting hole 111; the mounting hole 111 includes a first accommodating section 112, a spacing section 113 and a second accommodating section 114, the diameter of the spacing section 113 is smaller than the diameters of the first accommodating section 112 and the second accommodating section 114, the connecting member 21 includes a driving part 211, a sliding part 212 and a connecting part 213, the sliding part 212 can slide along the spacing section 113, and the diameter of the connecting part 213 is larger than the diameter of the spacing section 113, so that when the sliding part 212 slides along the spacing section 113, the connecting part 213 will be blocked by the spacing section 113 on one side of the second accommodating section 114, so that the connecting member 21 will not fall off from the mounting hole 111, eliminating the step of the operator taking the connecting member 21, and improving the working efficiency.

[0030] In some embodiments, see Figure 2 , the spacing section 113 is provided with an internal thread 1131, and the connecting portion 213 is provided with an external thread 2131 matched with the internal thread 1131, and the connecting portion 213 can be rotated through the spacing section 113 through the external thread 2131 and the internal thread 1131. In this way, the connecting member 21 can pass through the spacing section 113 through the external thread 2131 of the connecting portion 213 and the internal thread 1131 of the spacing section 113, so that when the connecting member 21 needs to be replaced, the connecting member 21 can be removed from the connecting end 11. It can be understood that the maximum diameter of the external thread 2131 is greater than the minimum diameter of the internal thread 1131, so that the spacing section 113 can block the connecting portion 213 on one side of the second accommodating section 114, and at the same time, when a force is applied to the connecting member 21 in the direction from the second accommodating section 114 to the first accommodating section 112, the connecting member 21 can also be removed.

[0031] In some embodiments, see Figure 2 and Figure 3Each set of connecting components 20 further includes an elastic member 22 and a limiting member 23. The elastic member 22 is sleeved on the sliding portion 212 and is disposed in the first accommodating section 112. The limiting member 23 is sleeved on the elastic member 22 and abuts against the driving portion 211. The limiting member 23 can slide in the first accommodating section 112. The elastic member 22 and the limiting member 23 cooperate to limit the position of the connecting member 21. The elastic member 22 is, for example, a spring or the like. The driving portion 211 of the connecting member 21 is abutted by the elastic member 22, so that when the connecting member 21 is not in use, the connecting portion 213 is accommodated in the second accommodating section 114, so as to facilitate the connection between the connecting arm 100 and the product 400. It can also prevent the connecting portion 213 from scratching the product 400 when the connecting arm 100 and the product 400 are assembled. The limiting member 23 can protect the elastic member 22 and can also limit the connecting member 21 when the connecting member 21 slides along the mounting hole 111 to prevent the connecting member 21 from being misplaced during use.

[0032] In some embodiments, see Figure 3 The rotating shaft 410 is provided with a clamping hole 412, and the main body 10 further includes a clamping block 12 corresponding to the clamping hole 412, the clamping block 12 is connected to the connecting end 11, and the connecting arm 100 is clamped with the rotating shaft 410 through the clamping block 12. By providing the clamping block 12 connected to the connecting end 11, the connecting arm 100 can be quickly clamped with the rotating shaft 410 of the product 400, which is convenient for positioning between the connecting arm 100 and the product 400. After the operator clamps the connecting arm 100 with the rotating shaft 410 of the product 400 through the clamping block 12, the connecting member 21 can be connected with the rotating shaft 410 of the product 400, which is convenient, fast and efficient.

[0033] See also Figure 4 An embodiment of the present application provides a protective device 300 , including a positioning assembly 310 , a connecting arm 100 , a supporting assembly 320 , a pressing assembly 330 and a protective mechanism 340 .

[0034] Specifically, see Figure 5 and Figure 8 , the positioning assembly 310 is used to carry the product 400 and position the product 400; the supporting assembly 320 is used to carry the connecting arm 100, and the supporting assembly 320 and the positioning assembly 310 are arranged adjacent to each other, so that when the connecting arm 100 is placed on the supporting assembly 320, the clamping block 12 can be clamped with the product 400; the pressing assembly 330 includes a first driving member 331 and a pressing member 332, the first driving member 331 is used to drive the pressing member 332 to rise and fall and rotate, so that the pressing member 332 can press the connecting arm 100 on the supporting assembly 320, and the first driving member 331 is, for example, a lifting and rotating cylinder or the like; please refer to Figure 6The protection mechanism 340 includes a second driving member 341 and a shielding member 342. The second driving member 341 is used to drive the shielding member 342 to move so that the shielding member 342 can shield the product 400 when the connecting arm 100 is connected or disassembled from the product 400. The second driving member 341 is, for example, a cylinder, a motor or other device. After the product 400 is placed on the positioning assembly 310, the second driving member 341 drives the shielding member 342 to move to shield the position of the product 400 that is not used for connection.

[0035] The working process of the protection device 300 provided in some embodiments is roughly as follows: during assembly, first, the product 400 is placed on the positioning assembly 310, and the positioning assembly 310 is used to position the product 400 so that the rotating shaft 410 of the product 400 is placed at a position to be connected to the connecting arm 100. Then the second driving member 341 in the protection mechanism 340 drives the shielding member 342 to move, shielding the position of the product 400 that is not used for connection. Figure 7, then the first driving member 331 drives the holding member 332 to move away from the first driving member 331, and rotates the holding member 332 to a certain angle, such as 90°, so as to facilitate the installation of the connecting arm 100. After the first driving member 331 stops moving, the connecting arm 100 is placed on the supporting assembly 320, and the clamping block 12 is engaged with the rotating shaft 410. At this time, the first driving member 331 drives the holding member 332 to rotate and move toward the connecting arm 100, thereby pressing the connecting arm 100 on the supporting assembly 320. Then, the connecting member 21 on the connecting arm 100 can be connected to the rotating shaft 410 of the product 400 through an external driving mechanism, so that the connection between the product 400 and the connecting arm 100 can be completed. After the connection is completed, the second driving member 341 drives the shielding member 342 to move away from the product 400, and the first driving member 331 drives the holding member 332 to move away from the connecting arm 100, so that the connected product 400 and the connecting arm 100 can be removed, and then the torque detection is performed through the external detection device. During disassembly, first the first driving member 331 drives the holding member 332 to move away from the first driving member 331, and the holding member 332 is rotated a certain angle, and then the product 400 is placed on the positioning assembly 310. At this time, the connecting arm 100 is connected to the product 400. When placing the product 400, the connecting arm 100 is placed on the supporting assembly 320 together, and then the first driving member 331 drives the holding member 332 to rotate and move toward the connecting arm 100, and then the connecting arm 100 is pressed on the supporting assembly 320. Since the connecting arm 100 and the product 400 are still in a connected state, at this time, by pressing the connecting arm 100 on the supporting assembly 320, the rotating shaft 410 can be driven to rotate, so that the rotating shaft 410 is restored to its original angle. After the product 400 and the connecting arm 100 are positioned, the second driving member 341 drives the shielding member 342 to move to shield the position of the product 400 that is not used for connection, and then the connecting member 21 on the connecting arm 100 and the rotating shaft 410 of the product 400 are separated by an external driving mechanism. After the separation is completed, the second driving member 341 drives the shielding member 342 to move away from the product 400, and the first driving member 331 drives the holding member 332 to move away from the connecting arm 100, so that the product 400 and the connecting arm 100 can be removed respectively.

[0036] The protective device 300 provided in the embodiment of the present application is convenient for positioning the product 400 by setting a positioning component 310, and is convenient for positioning the connecting arm 100 by setting a supporting component 320. The positioning component 310 and the supporting component 320 cooperate with each other to facilitate the connection between the product 400 and the connecting arm 100. The pressing component 330 can improve the stability of the connecting arm 100 when assembling the connecting arm 100 of the product 400, and facilitate the connection between the connecting piece 21 and the rotating shaft 410 of the product 400. The connecting arm 100 can also be pressed when disassembling the connecting arm 100, so that the connecting arm 100 drives the rotating shaft 410 of the product 400 to rotate to the initial angle position. The protective mechanism 340 is provided to protect the product 400 when assembling or disassembling the product 400 and avoid scratching the product 400. The protective device 300 provided in the present application drives the shielding member 342 to move through the first driving member 331. When assembling the product 400 and the connecting arm 100, it can provide protection for the product 400 to prevent the surface of the product 400 from being scratched. It has low cost, reduces the operation process, and improves work efficiency.

[0037] In some embodiments, see Figure 6 The positioning assembly 310 includes a support member 311 and a side positioning member 312. The side positioning member 312 is arranged on the side of the support member 311. The support member 311 is used to support the product 400, and the side positioning member 312 is used to position the product 400. The support member 311 is, for example, a plate-shaped structure that can carry the product 400. The size of one side of the support member 311 used to carry the product 400 is adapted to the product 400. The side positioning member 312 is, for example, a strip-shaped, plate-shaped structure. Multiple side positioning members 312 can be provided, for example, two, three, etc., to limit the product 400 from multiple angles. In this way, it is convenient to install the product 400 on the positioning assembly 310 and to position the product 400.

[0038] In some embodiments, see Figure 8 A through hole 420 is provided in the middle of the product 400, and the positioning assembly 310 further includes a precise positioning member 313 that matches the through hole 420. The precise positioning member 313 is disposed on the support member 311 and is used to match the through hole 420 to position the product 400. It can be understood that the precise positioning member 313 corresponds to the through hole 420 structure on the product 400, so that the product 400 can be precisely positioned by matching the through hole 420 of the product 400 with the precise positioning member 313.

[0039] In some embodiments, see Figure 6The positioning assembly 310 further includes a vacuum pump 314, the support member 311 is a vacuum suction plate 3111, the vacuum pump 314 is connected to the vacuum suction plate 3111, and the vacuum pump 314 sucks air from the vacuum suction plate 3111 to generate negative pressure, thereby adsorbing the product 400 on the vacuum suction plate 3111. In this way, after the product 400 is placed on the vacuum suction plate 3111 and positioned by the side positioning member 312 and the precise positioning member 313, the product 400 can be adsorbed on the vacuum suction plate 3111 by the vacuum pump 314, so that the position of the product 400 is fixed, and the product 400 is prevented from shifting during other operations.

[0040] In some embodiments, please refer to Figure 6 The vacuum suction plate 3111 is provided with a sealing groove 3112, which surrounds one side of the vacuum suction plate 3111 for carrying the product 400. The precise positioning member 313 is also provided with a sealing groove 3112 around it, and a sealing strip 3113 is provided in the sealing groove 3112. The sealing strip 3113 is used to contact the product 400 to play a sealing role. The sealing strip 3113 is, for example, a rubber strip, and the sealing strip 3113 protrudes from the sealing groove 3112, so that when the product 400 is placed on the vacuum suction plate 3111, the sealing strip 3113 contacts the product 400. In this way, by providing the sealing strip 3113, the sealing effect of the vacuum suction plate 3111 can be improved, and the adsorption effect of the vacuum pump 314 on the product 400 can be further improved. At the same time, the sealing strip 3113 can also prevent the product 400 from contacting the vacuum suction plate 3111, thereby reducing the risk of scratching the surface of the product 400.

[0041] In some embodiments, see Figure 5 and Figure 8 The support assembly 320 is provided with a profiling groove 321, which is adapted to the connecting arm 100 and is used to position the connecting arm 100. Thus, by providing the profiling groove 321, the connecting arm 100 is conveniently installed quickly, and the connecting arm 100 can be positioned by the profiling groove 321, so that the connecting piece 21 of the connecting arm 100 corresponds to the product 400.

[0042] In some embodiments, see Figure 8 The protective mechanism 340 is provided with two groups, which are respectively provided on both sides of the support assembly 320, so that the shielding member 342 shields the product 400 from both sides of the support assembly 320. In this way, the protective mechanism 340 can quickly shield the product 400, thereby improving the working efficiency. Figure 5 and Figure 8, the shielding member 342 is provided with an avoidance groove 3421, which corresponds to the connection end 11, so that when the shielding member 342 blocks the product 400, the shielding member 342 avoids the connection end 11 through the avoidance groove 3421. By setting the avoidance groove 3421, the shielding members 342 of the two sets of protection mechanisms 340 can avoid the connection end 11 when blocking the product 400, so as to avoid the shielding member 342 and the connection end 11 from being scratched and affecting the operation of the shielding member 342. It can be understood that when the shielding member 342 blocks the product 400, the avoidance groove 3421 exposes the position of the rotating shaft 410 of the product 400 to be connected with the connecting arm 100. When the connecting arm 100 is installed on the supporting assembly 320, the connecting end 11 is located at the position of the avoidance groove 3421, and cooperates with the shielding member 342 to completely block the position of the product 400 to be connected.

[0043] In some embodiments, see Figure 6 and Figure 8 The protection mechanism 340 further includes a slide rail 343 and a connecting rod 344. The shielding member 342 is slidably connected to the slide rail 343. The connecting rod 344 is respectively connected to the second driving member 341 and the shielding member 342, so that the second driving member 341 drives the shielding member 342 to slide along the slide rail 343 through the connecting rod 344. In this way, by setting the slide rail 343, the shielding member 342 can be moved along the slide rail 343, thereby limiting the movement trajectory of the shielding member 342, and allowing the shielding member 342 to move along a preset trajectory, thereby improving the stability of the operation of the shielding member 342 and preventing the shielding member 342 from deflecting during the movement, thereby preventing the product 400 from being scratched.

[0044] In some embodiments, see Figure 6 The protection mechanism 340 further includes a buffer assembly 345, which includes a connection seat 3451, a slide bar 3453 and a buffer 3454. Both ends of the slide bar 3453 are connected to the connection seat 3451, and the buffer 3454 is sleeved on the slide bar 3453. The second driving member 341 is connected to the shielding member 342 through the buffer assembly 345. The output end of the second driving member 341 is connected to the side of the connection seat 3451 away from the slide bar 3453, and the end of the connection bar 344 away from the shielding member 342 is slidably connected to the slide bar 3453, wherein the buffer 3454 is used to buffer the connection bar 344 when the protection mechanism 340 moves. The buffer 3454 is, for example, a spring, a rubber pad, or the like. When the second driving member 341 drives the shielding member 342 to move through the buffer assembly 345 and the connecting rod 344, the buffer 3454 can buffer the connecting rod 344, that is, also buffer the shielding member 342, to prevent the shielding member 342 from a high-intensity impact. The buffer assembly 345 only includes the connecting seat 3451, the sliding rod 3453 and the buffer 3454, which can achieve the buffering effect, with low cost and small space occupation.

[0045] In some embodiments, see Figure 6 and Figure 8 The connecting seat 3451 is provided with two limiting protrusions 3452, and the two ends of the slide bar 3453 are respectively connected to the two limiting protrusions 3452, so that the connecting rod 344 slides along the slide bar 3453 between the two limiting protrusions 3452. There are two buffers 3454, which are respectively provided on both sides of one end of the connecting rod 344 used for connecting the slide bar 3453, and are used to buffer the two sides of the connecting rod 344. In this way, by providing two buffers 3454, when the second driving member 341 drives the shielding member 342 to move toward the product 400, and when the shielding member 342 is driven to move away from the product 400, the connecting rod 344 and the shielding member 342 can be buffered, thereby improving the buffering effect.

[0046] In some embodiments, see Figure 4 The protective device 300 also includes a locking assembly 350, which includes an adjusting member 351 and a locking member 352. The adjusting member 351 is disposed adjacent to the supporting assembly 320, and the locking member 352 is connected to the adjusting member 351. The adjusting member 351 is used to limit the position of the locking member 352, and the locking member 352 is used to connect or disassemble the connecting member 21 and the product 400. The adjusting member 351 is, for example, a device such as a universal adjusting arm that can support the locking member 352, and the locking member 352 is, for example, a device such as an electric screwdriver that can connect or disassemble the connecting member 21 and the product 400. The arrangement of the adjusting member 351 makes it convenient for operators to take the locking member 352, thereby improving the efficiency of connecting and disassembling the product 400 and the connecting arm 100.

[0047] The working process of the protective device 300 provided in some embodiments is roughly as follows: during assembly, first, place the product 400 on the vacuum suction plate 3111 of the positioning assembly 310, and position the product 400 through the side positioning member 312 and the precise positioning member 313. After positioning is completed, turn on the vacuum pump 314, adsorb the product 400 on the vacuum suction plate 3111, and then turn on the two sets of second driving members 341. The two sets of second driving members 341 drive the shielding member 342 to move along the slide rail 343 to shield the part of the product 400 to be connected to the connecting arm 100, and at the same time, the avoidance groove 3421 exposes the position of the product 400 to be connected. After shielding is completed, the first driving member 331 drives the holding member 332 to move away from the first driving member 331, and rotates the holding member 332 to a certain angle, such as 90°, to facilitate the installation of the connecting arm 100. After the first driving member 331 stops moving, the connecting arm 100 is placed in the contoured groove 321 of the supporting assembly 320, and the clamping block 12 is engaged with the rotating shaft 410. At this time, the first driving member 331 drives the holding member 332 to rotate and move toward the connecting arm 100, thereby holding the connecting arm 100 against the supporting assembly 320. Then, the connecting member 21 is connected to the rotating shaft 410 of the product 400 through the locking member 352, and the connection between the product 400 and the connecting arm 100 is completed. After the connection is completed, the second driving member 341 drives the shielding member 342 to move away from the product 400, and the first driving member 331 drives the holding member 332 to move away from the connecting arm 100, and the connected product 400 and the connecting arm 100 can be removed.

[0048] During disassembly, the first driving member 331 first drives the holding member 332 to move away from the first driving member 331, and the holding member 332 is rotated to a certain angle, and then the product 400 is placed on the vacuum suction plate 3111, and the product 400 is positioned by the side positioning member 312 and the precise positioning member 313. After the positioning is completed, the vacuum pump 314 is turned on, the product 400 is adsorbed on the vacuum suction plate 3111, and then the first driving member 331 drives the holding member 332 to rotate and move toward the connecting arm 100, and then the connecting arm 100 is pressed against the supporting assembly 320. Since the connecting arm 100 and the product 400 are still in a connected state, at this time, by pressing the connecting arm 100 against the supporting assembly 320, the rotating shaft 410 can be driven to rotate, so that the rotating shaft 410 is restored to the initial angle. Then, the two sets of second driving members 341 are opened, and the two sets of second driving members 341 drive the shielding member 342 to move along the slide rail 343 to shield the part of the product 400 to be connected to the connecting arm 100. After the shielding is completed, the connecting member 21 and the rotating shaft 410 of the product 400 can be disassembled through the locking member 352. After the disassembly is completed, the second driving member 341 drives the shielding member 342 to move away from the product 400, and the first driving member 331 drives the holding member 332 to move away from the connecting arm 100. The vacuum pump 314 is turned off, and the product 400 and the connecting arm 100 can be removed respectively.
