[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figure 1-8 As shown, the present invention is a fully automatic U-bolt thread processing equipment, including a workbench 1, on which a steering mechanism 2 is provided; the steering mechanism 2 includes a mounting frame 201, a turntable 202 and a first cylinder 203. The mounting frame 201 is fixedly connected to the bottom of the workbench 1, and a column 204 is rotatably connected to the mounting frame 201. One end of the column 204 passes through a ratchet 205 and is fixedly connected to the bottom of the turntable 202. The turntable 202 is rotatably connected to a rotating hole 206, which is formed through the workbench 1. A collar 207 is rotatably connected to the column 204. The first cylinder 203 is rotatably connected to the mounting frame 201, and a push rod 208 is rotatably connected to the movable end of the first cylinder 203. One end of the push rod 208 is fixedly connected to the collar 207.

[0029] A push assembly 3 is provided on the push rod 208. The push assembly 3 includes a pawl 31 and a spring 32. A first shaft 33 is rotatably connected to the pawl 31. The first shaft 33 is fixedly connected to the push rod 208. One end of the spring 32 is fixedly connected to the pawl 31, and the other end of the spring 32 is fixedly connected to the push rod 208. The pawl 31 is matched with the ratchet 205.

[0030] A locking assembly 4 is provided on the turntable 202. The locking assembly 4 includes a second cylinder 41, a second shaft 42 is rotatably connected to the second cylinder 41, a pull rod 43 is rotatably connected to the movable end of the second cylinder 41, and a third shaft 44 is rotatably connected to the pull rod 43. The second shaft 42 and the third shaft 44 are both fixedly connected to the bottom of the worktable 1. A locking block 45 is fixedly connected to the pull rod 43. The locking block 45 is slidably connected in a slot 46. The slot 46 is opened on the turntable 202, and multiple slots 46 are provided.

[0031] The input ends of the first cylinder 203 and the second cylinder 41 are both connected to an external power source. The pawl 31 and the slot 46 are located below the worktable 1. The spring 32 is a tension spring, which makes the pawl 31 engage with the ratchet 205.

[0032] A support cylinder 209 is fixedly connected to the turntable 202, and an equipment box 210 is fixedly connected to the support cylinder 209. A rotating component 5 is provided inside the equipment box 210, and a ratchet 205 is fixedly connected to the column 204.

[0033] The first cylinder 203 pushes the push rod 208 to rotate, causing the pawl 31 to intermittently push the ratchet 205, column 204 and turntable 202 to rotate, thereby causing the support cylinder 209 to drive the upper rotating component 5 and clamping component 6 to rotate intermittently by a certain angle, so as to achieve the effect of adjusting the bolt angle to match the processing operation in different directions.

[0034] The rotating assembly 5 includes a first motor 51, a rotating rod 52, and a rotating box 53. The first motor 51 is installed inside the equipment box 210. The output end of the first motor 51 is fixedly connected to a main gear 54. The open end of the rotating box 53 is rotatably connected to a disc 55, which is fixedly connected to the open end of the equipment box 210. A through hole 56 is provided through the disc 55. One end of the rotating rod 52 passes through a first support plate 57 and is fixedly connected to a driven gear 58. The first support plate 57 is fixedly connected inside the equipment box 210. The other end of the rotating rod 52 passes through the through hole 56 and is fixedly connected inside the rotating box 53. A slot 59 is provided through the rotating box 53. The main gear 54 and the driven gear 58 mesh with each other. A clamping assembly 6 is provided on the rotating rod 52.

[0035] The input end of the first motor 51 is connected to an external power source. The rotation of the first motor 51, in conjunction with the transmission of the main gear 54 and the driven gear 58, causes the rotating rod 52 to drive the rotating box 53 to rotate, which in turn drives the two clamping plates 63 and the bolt to rotate, thereby achieving the effect of machining or polishing the bolt.

[0036] The clamping assembly 6 includes a second motor 61, a toothed tube 62, and a clamping plate 63. The second motor 61 is installed inside the equipment box 210. The output end of the second motor 61 is fixedly connected to a worm gear 64. A second support plate 65 is rotatably connected to the worm gear 64. The second support plate 65 is fixedly connected inside the equipment box 210. The other end of the worm gear 64 is rotatably connected to a disc 55. The toothed tube 62 is sleeved on a rotating rod 52. Two clamping plates 63 are symmetrically arranged.

[0037] Tooth tube 62 is a tubular toothed rack.

[0038] The toothed tube 62 and the rotating rod 52 are connected by a clearance fit to form a sliding-rotating connection. A connecting plate 66 is fixedly connected to each of the two clamping plates 63. The connecting plate 66 passes through the slot 59 and is fixedly connected to a sleeve 67. A threaded rod 68 is threadedly connected between the two sleeves 67. Both ends of the threaded rod 68 are rotatably connected to the rotating box 53. A first gear 69 is fixedly connected to the middle of the surface of the threaded rod 68. The first gear 69 meshes with the toothed tube 62.

[0039] The input end of the second motor 61 is connected to an external power source. The threads on both sides of the first gear 69 on the threaded rod 68 are two threads with opposite directions and equal pitch. When the threaded rod 68 rotates, it drives the two sleeves 67 on it to move closer or further away, which is similar to the effect of a bidirectional lead screw.

[0040] A connecting assembly 7 is provided between the worm 64 and the gear tube 62. The connecting assembly 7 includes a connecting rod 71, both ends of which are rotatably connected to the equipment box 210. A worm wheel 72 and a second gear 73 are respectively fixedly connected to the connecting rod 71. The worm wheel 72 meshes with the worm 64, and the second gear 73 meshes with the gear tube 62.

[0041] The rotation of the second motor 61, in conjunction with the meshing relationship between the worm gear 72 and the worm 64, the toothed tube 62 and the first gear 69, and the second gear 73, causes the threaded rod 68 to rotate, thereby achieving the effect of clamping the bolt between the two clamping plates 63. The U-bolt processing process should first batch process the threads at one end of the bolt rod, then batch process the threads at the other end, and finally perform batch stamping and testing.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0043] The working principle of this invention is as follows: The movable end of the first cylinder 203 shortens, causing the push rod 208, collar 207, and push assembly 3 to rotate. The pawl 31 engages with the ratchet 205. Then, the movable end of the second cylinder 41 extends, causing the pull rod 43 to rotate, thereby causing the locking block 45 to move away from the slot 46. Next, the movable end of the first cylinder 203 extends, causing the pawl 31 to push the ratchet 205, column 204, and turntable 202 to rotate. Finally, the movable end of the first cylinder 203 shortens, causing the pull rod 43 to rotate and causing the locking block 45 to engage into the corresponding slot 46, realizing one rotation of the turntable 202. This process is repeated. This process allows the bolt to be intermittently rotated to other positions. The first motor 51 drives the main gear 54 to rotate, which in turn drives the rotating box 53 to rotate via the driven gear 58 and the rotating rod 52. This, in turn, drives the threaded rod 68, sleeve 67, connecting plate 66, and clamping plate 63 to rotate. The second motor 61 drives the worm gear 64 to rotate, which in turn drives the connecting rod 71 and the second gear 73 to rotate via the worm wheel 72. This causes the toothed tube 62 to slide on the surface of the rotating rod 52, which in turn drives the first gear 69 and the threaded rod 68 to rotate. This causes the two sleeves 67 to drive the two connecting plates 66 and clamping plate 63 to move towards each other and clamp the bolt.

[0044] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
