Furthermore, in one or more embodiments, the specialized features, structures, or characteristics may be combined in any suitable manner.

[0052] Please also read Figures 1 to 9 The belt tensioner press-fit detection integrated device provided by the embodiment of the present invention is now described. Figure 1 , Figure 2 , Figure 3 and Figure 6 The belt tensioner press-fitting and testing integrated equipment provided in the embodiment of the present invention includes an operating table 1, a positioning tool 2, a moving mechanism 3, a pressing device 4, a height detection device 5 and a code scanning device 6. Different positions on the operating table 1 are correspondingly provided with a loading station for operators to load materials, a pressing station for pressing bolts 30, a detection station for detecting the height of the bolts 30 and a code scanning station for code scanning detection. The positioning tool 2 is movably arranged on the operating table 1, and the positioning tool 2 can position the tensioner body 50 to be pressed. The moving mechanism 3 can drive the positioning tool 2 and the tensioner body 50 on the positioning tool 2 to move to the pressing station, the detection station and the code scanning station in sequence. The pressing device 4 is arranged at a position corresponding to the pressing station on the operating table 1, and the pressing device 4 can press the bolt 30 (such as Fig.12 The height detection device 5 is arranged at a position corresponding to the detection station on the operating table 1, and the height detection device 5 can detect the height of the bolt 30 with the bushing 40 after being pressed into the mounting hole. The code scanning device 6 is arranged at a position corresponding to the code scanning station on the operating table 1, and the code scanning device 6 can scan and identify the tensioner after being pressed, so as to determine whether the tensioner after being pressed is qualified.

[0053] When the belt tensioner press-fitting and testing integrated device provided by the embodiment of the present invention is working, the positioning fixture 2 is located at the loading station on the operating table 1, and the operator places the tensioner body 50 to be press-fitted on the positioning fixture 2. After the tensioner body 50 to be press-fitted is positioned on the positioning fixture 2, the moving mechanism 3 drives the positioning fixture 2 to move to the press-fitting station, and the press-fitting device 4 then presses the bolt 30 with the bushing 40 into the mounting hole on the tensioner body 50. After the press-fitting device 4 presses the bolt 30 with the bushing 40 into the mounting hole on the tensioner body 50, the moving mechanism 3 drives the positioning fixture 2 to move to the testing station, and the height of the bolt 30 with the bushing 40 after being press-fitted into the mounting hole is detected by the height detection device 5. When the height of the bolt 30 with the bushing 40 after being pressed into the installation hole does not meet the preset standard, it is judged as unqualified, and the moving mechanism 3 drives the positioning tool 2 to move to the loading station for unloading, and then the operator places another tensioner body 50 to be pressed on the positioning tool 2. When the height of the bolt 30 with the bushing 40 after being pressed into the installation hole meets the preset standard, it is judged as qualified, and the moving mechanism 3 drives the positioning tool 2 to move to the code scanning station, and the code scanning device 6 scans and identifies the tensioner after being pressed. If the code scanning device 6 does not meet the preset standard when scanning the code, it is judged as unqualified, and the moving mechanism 3 drives the positioning tool 2 to move to the loading station for unloading, and then the operator places another tensioner body 50 to be pressed on the positioning tool 2. If the code scanning device 6 determines that the product is qualified when the code scanning detection reaches the preset standard, the moving mechanism 3 drives the positioning fixture 2 to move to the loading station for unloading, and then the operator unloads the qualified product and places another tensioner body 50 to be pressed on the positioning fixture 2 for press-fitting detection. This is repeated, and the press-fitting and detection operations of the bolt 30 and the tensioner body 50 are automatically completed at one time through the belt tensioner press-fitting and detection integrated equipment. The press-fitting and detection production cycle of a single product can be shortened to 10 seconds, which can not only reduce the labor intensity of the operator and improve the efficiency of tensioner assembly and detection, but also ensure that the assembly and detection of the tensioner have good consistency.

[0054] Compared with the prior art, the belt tensioner press-fitting and testing integrated device provided in the embodiment of the present invention has a loading station, a press-fitting station, a testing station and a code scanning station correspondingly arranged at different positions on the operating table 1. After the operator places the tensioner body 50 to be press-fitted on the positioning fixture 2 at the loading station, the moving mechanism 3 drives the positioning fixture 2 to move to the pressing station, and the bolt 30 with the bushing 40 is pressed into the mounting hole on the tensioner body 50 by the pressing device 4 on the pressing station. The moving mechanism 3 then drives the positioning fixture 2 to move to the testing station, and the height of the bolt 30 with the bushing 40 after being pressed into the mounting hole is detected by the height detection device 5 on the testing station. The moving mechanism 3 then drives the positioning fixture 2 to move to the code scanning station, and the code scanning device 6 on the code scanning station scans and identifies the tensioner after press-fitting. In this way, the pressing and testing operations of the bolt 30 and the tensioner body 50 can be automatically completed at one time through the belt tensioner pressing and testing integrated equipment, which can not only reduce the labor intensity of the operating workers and improve the efficiency of tensioner assembly and testing, but also ensure that the tensioner assembly and testing have good consistency.

[0055] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the press-fitting device 4 includes a press-fitting bracket 41 arranged at a corresponding press-fitting station on the operating table 1, a sliding seat 42 slidably arranged on the press-fitting bracket 41, a clamping mechanism 43 for clamping the bolt 30 with a bushing 40, and a first linear drive mechanism 44 for driving the sliding seat 42 to move toward the positioning tool 2, the clamping mechanism 43 is arranged on the sliding seat 42, the first linear drive mechanism 44 is arranged on the press-fitting bracket 41, and the sliding seat 42 is connected to the power output end of the first linear drive mechanism 44. In this embodiment, the operator only needs to place the bolt 30 with the bushing 40 on the clamping mechanism 43, and the clamping mechanism 43 can firmly clamp and position the bolt 30 with the bushing 40, and can ensure that the bolt 30 with the bushing 40 is aligned with the mounting hole of the tensioner body 50 on the positioning fixture 2. The first linear drive mechanism 44 drives the sliding seat 42 to move toward the tensioner body 50 on the positioning fixture 2, and the sliding seat 42 drives the clamping mechanism 43 to move, and the clamping mechanism 43 further drives the bolt 30 with the bushing 40 to move toward the tensioner body 50 on the positioning fixture 2 until the bolt 30 with the bushing 40 is pressed into the mounting hole on the tensioner body 50, and the clamping mechanism 43 loosens the bolt 30, and the first linear drive mechanism 44 drives the sliding seat 42 and the clamping mechanism 43 on the sliding seat 42 to return to the initial position, completing the press-fitting of the bolt 30 and the tensioner body 50. It should be noted that the first linear drive mechanism 44 can be, but is not limited to, a cylinder.

[0056] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the press-fitting device 4 further includes a first guide assembly 45 for guiding the sliding seat 42 to move up and down. The first guide assembly 45 includes a plurality of first sleeves 451 provided on the press-fitting bracket 41 and a first guide column 452 slidably inserted in the first sleeves 451 along the axial direction. The number of the first sleeves 451 is consistent with the number of the first guide columns 452, and the first sleeves 451 and the first guide columns 452 are arranged one by one. The sliding seat 42 is connected to the plurality of first guide columns 452, so that the sliding seat 42 is slidably installed on the first bracket 451 through the first guide assembly 45, and the sliding seat 42 is guided to move up and down by the first guide assembly 45, which can ensure the stability and reliability of the sliding seat 42 moving up and down, so as to facilitate the press-fitting device 4 to accurately press-fit the bolt 30 with the bushing 40 into the mounting hole on the tensioner body 50.

[0057] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the press-fit device 4 further includes a positioning seat 46 disposed on the sliding seat 42, and a positioning hole 461 is provided on the positioning seat 46 for inserting the head of the bolt 30. The operator only needs to insert the head of the bolt 30 into the positioning hole 461 to achieve the position of the positioning bolt 30, so that the bolt 30 can be aligned with the mounting hole of the tensioner body 50 on the positioning tool 2, thereby facilitating the press-fit device 4 to accurately press-fit the bolt 30 with the bushing 40 into the mounting hole on the tensioner body 50. In addition, a magnetic suction member 47 for adsorbing the bolt 30 is provided in the positioning hole 461, and the bolt 30 can be adsorbed in the positioning hole 461 by the magnetic suction member 47, so that the operator can quickly achieve the positioning of the bolt 30. In addition, after the press-fitting device 4 accurately presses the bolt 30 with the bushing 40 into the mounting hole on the tensioner body 50, when the first linear drive mechanism 44 drives the sliding seat 42 and the positioning seat 46 on the sliding seat 42 to retract, it only needs to overcome the magnetic attraction force of the magnetic part on the bolt 30 to quickly achieve the separation of the sliding seat 42 and the bolt 30, which is beneficial to improve the press-fitting efficiency of the tensioner.

[0058] Please refer to Figure 4 In some embodiments, an elastic member 48 supporting the magnetic member 47 is further provided in the positioning hole 461, and the elastic member 48 plays a floating supporting role on the magnetic member 47 through elasticity, so as to prevent the magnetic member 47 from being damaged due to excessive pressure of the bolt 30 against the magnetic member 47 during the process of press-fitting the bolt 30. It should be noted that the magnetic member 47 can be a magnet, or an electromagnet. The elastic member 48 can be a spring, or an elastic pad such as rubber.

[0059] Please refer to Figure 3 , Figure 4 and Figure 5 In some embodiments, the clamping mechanism 43 includes a pair of clamping jaws 431, a clamping jaw cylinder 432 driving the two clamping jaws 431 to move away from or toward each other, and a positioning block 433 provided inside the clamping jaws 431 to limit the position of the bushing 40 on the bolt 30, the top end surface of the positioning block 433 abuts against the head of the bolt 30, and the bottom end surface of the positioning block 433 abuts against the top end of the bushing 40. When the operator positions the bolt 30 with the bushing 40 in the positioning hole 461 of the positioning seat 46, the clamping jaw cylinder 432 drives the two clamping jaws 431 to move toward each other, and the positioning block 433 inside the clamping jaw 431 firmly clamps and positions the bolt 30 with the bushing 40. While the two positioning blocks 433 clamp the positioning bolt 30, the top end surface of the positioning block 433 abuts against the head of the bolt 30, and the bottom end surface of the positioning block 433 abuts against the top end of the bushing 40, which can limit the bushing 40 and prevent the bushing 40 from moving during the process of pressing the bolt 30, thereby limiting the bushing 40 to a preset position on the bolt 30.

[0060] Please refer to Figure 5 In some embodiments, an arc-shaped engaging groove 434 adapted to the bolt 30 is provided on the side of the positioning block 433 facing the bolt 30. The arc groove surface of the engaging groove contacts the bolt 30, which is beneficial to increase the contact area between the positioning block 433 and the bolt 30. On the one hand, it can enhance the firmness of the positioning block 433 in clamping the positioning bolt 30, and on the other hand, it can prevent the positioning block 433 from scratching the bolt 30.

[0061] Please refer to Figure 1 , Figure 2 and Figure 7 In some embodiments, the height detection device 5 includes a first support frame 51 arranged at a corresponding detection station on the operating table 1, a first sliding support frame 52 slidingly arranged on the first support frame 51, a plurality of displacement sensors 53 arranged on the first sliding support frame 52, and a second linear drive mechanism 54 driving the first support frame 51 to move toward the positioning fixture 2, wherein the plurality of displacement sensors 53 are arranged at intervals, and the plurality of displacement sensors 53 are located on the same horizontal plane. In this embodiment, when the moving mechanism 3 drives the positioning fixture 2 to move to the detection station, the cylinder drives the first sliding support frame 52 and the plurality of displacement sensors 53 on the first sliding support frame 52 to move toward the tensioner body 50 on which the bolt 30 is pressed, and the plurality of displacement sensors 53 located on the same horizontal plane contact the tensioner body 50 to ensure the height of the tensioner body 50 is balanced and tested, thereby ensuring the accuracy of the height of the bolt 30 with the bushing 40 pressed into the mounting hole by the height sensor. It should be noted that the second linear drive mechanism 54 can be, but is not limited to, a cylinder.

[0062] Please refer to Figure 1 , Figure 2 and Figure 8 In some embodiments, the height detection device 5 further includes a second guide assembly 55 for guiding the first sliding bracket 52 to move up and down. The second guide assembly 55 includes a plurality of second sleeves 551 provided on the first support frame 51 and a second guide column 552 slidably inserted in the second sleeves 551 along the axial direction. The number of the second sleeves 551 is consistent with the number of the second guide columns 552, and the second sleeves 551 and the second guide columns 552 are arranged one by one. The first sliding bracket 52 is connected to the plurality of second guide columns 552, so that the first sliding bracket 52 is slidably installed on the first support frame 51 through the second guide assembly 55, and the first sliding bracket 52 is guided to move up and down by the second guide assembly 55, so that the stability and reliability of the up and down movement of the first sliding bracket 52 can be ensured, thereby facilitating the accuracy of the balance test of the tensioner body 50 by the plurality of displacement sensors 53 on the height detection device 5.

[0063] Please refer to Figure 7 In some embodiments, in order to further improve the accuracy of the balance test of the tensioner body 50 by the multiple displacement sensors 53, the multiple displacement sensors 53 are arranged in a ring shape, and the distance between two adjacent displacement sensors 53 is equal. It should be noted that the number of displacement sensors 53 can be more than 3.
