[0029] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] Reference Figure 1 - Figure 2 , Figure 4 The utility model provides an embodiment: an automatic nut tightening machine, including a nut tightening machine body 1, a fixing fixture 2 is arranged on the front surface of the nut tightening machine body 1, the fixing fixture 2 is a prior art, and can be manufactured and replaced according to the appearance of the product to ensure the stability of clamping and fixing, and can be realized by technicians in this field. Since it is a prior art, it will not be described in detail in this case. A material picking component 3 is arranged on the inner wall of the fixing fixture 2, and a moving component 4 is arranged on the inner wall of the bottom end of the nut tightening machine body 1. The material picking component 3 includes a round rod 32, the round rod 32 passes through the lower surface of the rear end of the fixing fixture 2 and is slidably connected, a fixed plate 31 is fixedly connected to the upper surface of the round rod 32, and a spring 34 is sleeved on the outer wall of the round rod 32. The spring 34 always pulls the round rod 32 upward by its own elasticity, which can increase the material picking speed. One end of the spring 34 is fixedly connected to the inner wall of the bottom end of the rear side of the fixing fixture 2, and the other end of the spring 34 is fixedly connected to the upper surface of the round rod 32.

[0031] Reference Figure 1 , Figure 3 The moving assembly 4 includes a rotating rod 46, which is rotatably connected to the inner wall at the bottom end of the nut tightening machine body 1. A motor 41 is fixedly connected to the right surface of the rotating rod 46. The motor 41 is a prior art and can be implemented by technicians in this field. Since it is a prior art, it will not be described in detail in this case. The motor 41 is fixedly connected to the right surface at the bottom end of the nut tightening machine body 1. A connecting plate 45 is fixedly connected to the outer wall at the left end of the rotating rod 46. When the connecting plate 45 is in a vertical state, the roller 42 contacts the ground to adjust the position of the nut tightening machine body 1. If the connecting plate 45 is tilted, the roller 42 is stored inside the bottom end of the nut tightening machine body 1 to ensure the stability of the nut tightening machine body 1 when parked.

[0032] Reference Figure 2 , Figure 4 The material picking component 3 also includes a rectangular shell 33, which is slidably connected to the inner wall of the top end of the rear side of the fixing fixture 2. The upper surface of the rear end of the rectangular shell 33 is threadedly connected with a threaded rod 38. The threaded rod 38 is a prior art, which is a rod-shaped structure with a threaded outer wall. When rotating, the structure connected to its outer wall will move linearly. At the same time, it has the characteristic of axial self-locking to ensure the stability of the structural connection. The threaded rod 38 penetrates and is rotatably connected to the upper surface of the rear end of the fixing fixture 2.

[0033] Reference Figure 2 , Figure 4 A handle 37 is slidably connected to the right surface of the rectangular shell 33, and a blocking block 35 is fixedly connected to the left surface of the handle 37. The blocking block 35 is slidably connected to the inner wall of the rectangular shell 33, and a spring 2 36 is sleeved on the outer wall of the handle 37. The spring 2 36 has a certain elasticity and always pushes the blocking block 35 to the left to ensure its stability in blocking the product. One end of the spring 2 36 is fixedly connected to the inner wall of the rectangular shell 33, and the other end of the spring 2 36 is fixedly connected to the right surface of the blocking block 35. The left surface of the blocking block 35 is set to an inclined surface. The set inclined surface can increase the speed of placing the product into the fixing fixture 2, thereby improving work efficiency.

[0034] Reference Figure 3The moving component 4 also includes a slide plate 43, which is slidably connected to the inner wall of the bottom end of the nut tightening machine body 1. A rectangular groove 44 is provided on the inner wall of the slide plate 43. When the connecting plate 45 drives the slide bar 47 to move to the front end of the inner wall of the rectangular groove 44, it will no longer be able to move. At this time, the roller 42 will contact the ground and support the nut tightening machine body 1, so that the nut tightening machine body 1 can be moved to adjust its position. A roller 42 is provided on the lower surface of the slide plate 43. The roller 42 is a prior art, which is a universal wheel and can adjust the direction of movement at will. The right surface of the bottom end of the connecting plate 45 is rotatably connected with a slide bar 47, and the slide bar 47 is slidably connected to the inner wall of the rectangular groove 44.

[0035] The nut tightening machine body 1 can be started to process the product by putting the product into the fixing fixture 2. When the product is put into the fixing fixture 2, the front end of the product will push it to move along the inclined surface of the blocking block 35, and the blocking block 35 will squeeze the spring 2 36. At the same time, the product will contact the fixed plate 31 and push the fixed plate 31 to move. The fixed plate 31 will drive the round rod 32 to move and stretch the spring 1 34 until the product moves to the bottom of the blocking block 35. At this time, the spring 2 36 will push the blocking block 35 to move in the opposite direction through its own elasticity to block the product, ensuring the stability of the fixation. After the processing is completed, pull the handle 37 to release the blocking of the product by the blocking block 35. At this time, the spring 1 34 will pull the round rod 32 upward through its own elasticity, and the round rod 32 will drive the fixed plate 31 to move upward to eject the product. Then the worker can directly take the product away to complete the material removal, which is quick and convenient. If the thickness of the product is different, the rectangular shell 33 can be driven by rotating the threaded rod 38 to ensure the accurate positioning of the product.

[0036] When the nut tightening machine body 1 needs to be moved, the motor 41 is started to drive the rotating rod 46 to rotate, and the rotating rod 46 will drive the connecting plate 45 to rotate. At this time, the sliding rod 47 will slide on the inner wall of the rectangular groove 44, and the sliding plate 43 will also move accordingly until the connecting plate 45 remains in a vertical state, so that the roller 42 will contact the ground and support the nut tightening machine body 1, so that the position of the nut tightening machine body 1 can be moved. When parking, the motor 41 is started to drive the rotating rod 46 to reverse, and the subsequent structural coordination method is the same as above, so that the roller 42 can be retracted into the inner wall of the nut tightening machine body 1, so that the lower surface of the nut tightening machine body 1 is in contact with the ground, thereby improving its stability.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
