[0037] S3. When the displacement monitoring component 6 monitors that the connecting seat 2 has been displaced to the specified position, stop driving the connecting seat 2.

[0038] Embodiment 2

[0039] Embodiment 2 is an improvement based on Embodiment 1: The clamping mechanism further includes a first connecting plate 8. The first connecting plate 8 is L-shaped and includes a mating plate 17 and a second fixing plate 28 which are integrally connected. The second fixing plate 28 is fixedly connected to the connecting seat 2. A locking mechanism for cooperating with the mating plate 17 to limit the feeding position of the catenary U-shaped clamp 1 is provided on the feeding table 16.

[0040] The mating plate 17 is a rectangular plate with a rounded corner.

[0041] Embodiment 3

[0042] Embodiment 3 is an improvement based on Embodiment 2: The locking mechanism includes a limiting plate 13 fixedly arranged on the feeding table 16. The limiting plate 13 is used to prevent the mating plate 17 from moving. A locking plate 12 that cooperates with the mating plate 17 is rotatably connected to the limiting plate 13. A fixing block 9 is fixedly connected to the feeding table 16. A second spring 10 is connected between the locking plate 12 and the fixing block 9.

[0043] The fixing block 9 is fixedly connected to the feeding table 16 through a third bolt 20. Second bolts 19 and fourth bolts 23 are respectively passed through the fixing block 9 and the locking plate 12. Hooks are fixedly connected to both ends of the second spring 10, and the two ends of the hooks are respectively arranged on the second bolts 19 and the fourth bolts 23. A limiting block 11 is fixedly connected to the locking plate 12, and a limiting groove is formed on the bottom surface of the feeding table 16. The limiting block 11 extends into the limiting groove of the feeding table 16. The locking mechanism further includes a fifth bolt 25 fixedly arranged on the limiting plate 13, and the locking plate 12 is sleeved on the fifth bolt 25.

[0044] As Figure 3 and Figure 4 , the locking plate 12 drives the limiting block 11 to rotate around the fifth bolt 25. Due to the limitation of the limiting block 11 and the feeding table 16, when the limiting block 11 falls into the limiting groove of the feeding table 16, the locking plate 12 cannot rotate in the clockwise direction.

[0045] During use, the connecting seat 2 is first pushed to move, and the first connecting plate 8 moves with the connecting seat 2. The first connecting plate 8 drives the matching plate 17 to move in the direction of the locking plate 12. The locking plate 12 is provided with a rounded corner. When the rounded corner of the matching plate 17 contacts the rounded corner of the locking plate 12, due to the restriction of the limit block 11 and the feed table 16, the locking plate 12 can only rotate counterclockwise. The locking plate 12 is staggered with the matching plate 17, the second spring 10 is compressed, and the matching plate 17 continues to move until the matching plate 17 contacts the limit plate 13. The second spring 10 resets and drives the locking plate 12 to rotate clockwise until the limit block 11 falls into the limit groove of the feed table 16. The locking plate 12 stops rotating and locks the matching plate 17 together with the limit plate 13.

[0046] Example 4

[0047] Example 4 is an improvement based on Example 3: the locking plate 12 includes a contact portion 21, a connecting portion 22, an arc portion 26 and a connecting portion 24 connected in sequence, the arc portion 26 is rotatably connected to the limit plate 13, the connecting portion 24 is connected to the second spring 10, and the mating plate 17 squeezes the contact portion 21 during the movement of the connecting seat 2 through the second fixing plate 28 to drive the locking plate 12 to rotate as a whole until the connecting portion 22 locks the position of the mating plate 17.

[0048] The rounded corner is set on the contact part 21, and the sixth bolt is passed through the contact part 21; the connecting part 22 is fixedly connected to the limit block 11; the fifth bolt 25 is set on the arc part 26; the fourth bolt 23 is set on the connecting part 24, and the connecting part 24 is connected to the second spring 10 through the fourth bolt 23.

[0049] The specific matching process between the matching plate 17 and the locking plate 12 is as follows: the matching plate 17 moves along with the connecting seat 2 through the first connecting plate 8. When the rounded corner of the contact portion 21 contacts the rounded corner of the matching plate 17, the matching plate 17 squeezes the contact portion 21. After the contact portion 21 is squeezed, the arc portion 26 is driven by the connecting portion 22 to rotate counterclockwise around the fifth bolt 25. The arc portion 26 drives the connecting portion 24 to move synchronously. The connecting portion 24 drives one end of the second spring 10 to move through the fourth bolt 23. The end of the second spring fixed to the fixing block 9 does not move, and the second spring 10 is stretched. The matching plate 17 continues to move until it touches the limit plate 13. The matching plate 17 Stop moving, the mating plate 17 is separated from the contact part 21 at this time, the second spring 10 starts to reset, and the second spring 10 drives the entire locking plate 12 to rotate clockwise around the fifth bolt 25 through the connecting part 24 until the limit block 11 falls into the limit groove of the feed table 16, the locking plate 12 stops rotating, the contact part 21 contacts the mating plate 17 and locks the mating plate 17 together with the limit plate 13. Since the mating plate 17 is fixedly connected to the connecting seat 2 through the second fixing plate 28, the position of the connecting seat 2 is fixed.

[0051] Example 5 is an improvement based on Example 2: A support plate 7 is fixedly arranged on the feeding table 16, the displacement monitoring assembly 6 is arranged through the support plate 7, and a plurality of first springs 4 are connected between the support plate 7 and the connecting seat 2.

[0052] In this embodiment, the number of the first springs 4 is two. The support plate 7 is fixedly connected with a first fixing plate 5, two first bolts 3 are fixedly arranged on both the first fixing plate 5 and the connecting seat 2, and two ends of the first spring 4 are respectively connected with the corresponding first bolts 3.

[0053] In this embodiment, the displacement monitoring assembly 6 adopts a displacement sensor. The displacement sensor is arranged through the support plate 7, and the sensing head of the displacement sensor is fixedly connected with the connecting seat 2.

[0054] During the process that the catenary U-bolt 1 is sent to the designated position, the first spring 4 is stretched under the action of tension, the sensing head of the displacement sensor moves synchronously with the connecting seat 2, and the feeding amount of the connecting seat 2 detected by the displacement sensor can obtain the position of the catenary U-bolt 1. After the catenary U-bolt 1 is sent to the designated position, the catenary U-bolt 1 is taken off from the clamping assembly, and then the sixth bolt on the contact part 21 is toggled by the manipulator, and the whole locking plate 12 rotates counterclockwise about the fifth bolt 25, and the contact part 21 is separated from the mating plate 17. The connecting seat 2 slides on the slide rail 15 towards the direction where the support plate 7 is located under the reset of the first spring 4; then the sixth bolt is loosened, the second spring 10 is reset, and the second spring 10 drives the locking plate 12 to rotate clockwise about the fifth bolt 25 until the limiting block 11 falls into the limiting groove of the feeding table 16, and the locking plate 12 is reset.

[0055] Example 6

[0056] Example 6 is an improvement based on Example 5: The connecting seat 2 includes a main body 38 and a second connecting plate 40 which are integrally connected. The main body 38 is connected with the first spring 4, the main body 38 is fixedly connected with the clamping assembly, the second connecting plate 40 is slidably arranged on the feeding table 16, and the second connecting plate 40 is fixedly connected with the second fixing plate 28.

[0057] The first bolt 3 is fixedly arranged on the main body 38. The main body 38 is connected with the first spring 4 through the first bolt 3. An installation groove is formed on the main body 38, and the catenary U-bolt 1 is located in the installation groove; the second connecting plate 40 is slidably arranged on the slide rail 35 through a slider 35, a groove 39 is formed on the second connecting plate 40, and the second fixing plate 28 is fixedly arranged in the groove 39.

[0058] Example 7

[0059] Embodiment 7 is an improvement based on Embodiment 6: The clamping assembly includes a connecting block 29 and two pin shafts 30. Two circular holes are formed in the connecting block 29. After the pin shafts 30 pass through the corresponding circular holes, they are fixedly connected to the main body 38. A third spring 31 is fixedly connected between the connecting block 29 and the main body 38. Two parallel elastic pieces 32 are arranged on the connecting block 29, and a pressing block 33 for pressing the bottom of the catenary U-shaped clamp 1 to the main body 38 is fixedly arranged on the elastic piece 32.

[0060] The pressing block 33 is spherical. The pressing block 33 is embedded in the elastic piece 32, and a part of the pressing block 33 extends between the two elastic pieces 32.

[0061] The clamping process of the catenary U-shaped clamp 1 is as follows: Push the connecting block 29 to move on the pin shaft 30 until the connecting block 29 contacts the main body 38, and the third spring 31 is compressed. After the catenary U-shaped clamp 1 is placed in the installation groove of the main body 1, release the connecting block 29, and the third spring 31 resets to drive the connecting block 29 to move away from the main body 1 on the pin shaft 30 until the two pressing blocks 33 press the semi-circular arc plate 37 of the catenary U-shaped clamp 1 in the installation groove, and the connecting block 29 stops moving.

[0062] When the catenary U-shaped clamp 1 is sent to the designated position, a connecting bolt is passed through the two through holes 36 to fix the catenary U-shaped clamp 1. Then, the sixth bolt is toggled, the locking plate 12 moves, and the first spring 4 drives the entire connecting seat 2 to move towards the direction of the support plate 7 through the main body 38. Since the catenary U-shaped clamp 1 is fixed, the pressing block 33 is squeezed, the elastic piece 32 deforms, the pressing block 33 crosses the semi-circular arc plate 37, and the clamping assembly is separated from the catenary U-shaped clamp 1.
