Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0030] Please refer to Figure 1-8, the utility model provides a technical solution: a long screw processing guiding device for a horizontal thread rolling machine, which includes a base 1, two fixed guiding plates 2, multiple guide rods 3, two movable guiding plates 4 and a guiding driving mechanism 5. The two fixed guiding plates 2 are fixedly connected to the base 1, and a first guiding chute 6 is formed between the two fixed guiding plates 2. The multiple guide rods 3 are fixedly connected to the two fixed guiding plates 2, and the multiple guide rods 3 are perpendicular to the surfaces of the fixed guiding plates 2. The two movable guiding plates 4 are slidably connected to the multiple guide rods 3, and a second guiding chute 7 is formed between the two movable guiding plates 4. The movable guiding plates 4 are parallel to the fixed guiding plates 2. The guiding driving mechanism 5 is slidably connected to the multiple guide rods 3, and the guiding driving mechanism 5 is located between the fixed guiding plates 2 and the movable guiding plates 4;

[0031] The guiding driving mechanism 5 includes a support plate 51, two clamping plates 52, two belt pulleys 53, a driving motor 54 and a synchronous belt 55. The support plate 51 is slidably connected to the multiple guide rods 3. The two clamping plates 52 are respectively fixedly connected to the opposite end faces of the support plate 51. The two belt pulleys 53 are respectively located on the opposite sides of the support plate 51. The belt pulleys 53 are hinged to the two clamping plates 52. The driving motor 54 is fixedly connected to any one of the clamping plates 52, and the driving motor 54 is connected to and drives any one of the belt pulleys 53. The synchronous belt 55 is sleeved on the support plate 51 and the two belt pulleys 53. The side surface of the support plate 51 abuts against the inner wall of the synchronous belt 55. The two belt pulleys 53 are both engaged with the synchronous belt 55. A plurality of positioning grooves 8 are formed on the outer wall of the synchronous belt 55, so that the whole guiding driving mechanism 5 can be adjusted along the guide rods 3. The driving motor 54 rotates to drive the belt pulley 53 to rotate, and the belt pulley 53 rotates to drive the synchronous belt 55 to run. The side surface of the support plate 51 has a stable supporting effect on the movement of the synchronous belt 55, so that the synchronous belt 55 drives the long screw located in the first guiding chute 6 and the second guiding chute 7 to move smoothly;

[0032] A plurality of limit nuts 9 are screwed on the guide rods 3. The limit nuts 9 respectively abut against the bottoms of the two movable guiding plates 4 and the bottom of the clamping plate 52 located below, and have an adjusting and supporting effect on the movable guiding plates 4 and the guiding driving mechanism 5;

[0033] The synchronous belt 55 is located between the two clamping plates 52. The two clamping plates 52 can limit the synchronous belt 55 well and prevent the synchronous belt 55 from shifting in position during movement;

[0034] The orthographic projection contour of the first guide chute 6 in the direction of the surface of the base 1 coincides with the orthographic projection contour of the second guide chute 7 in the direction of the surface of the base 1, ensuring the stable sliding of the long screw along the first guide chute 6 and the second guide chute 7;

[0035] The edge of the synchronous belt 55 extends into the orthographic projection contour of the first guide chute 6 in the direction of the surface of the base 1, ensuring that the long screw can be caught in the positioning groove 8.

[0036] Working principle: First, according to the length of the long screw to be processed, slide and adjust the position of the movable guide plate 4 along the guide rod 3. After the adjustment of the movable guide plate 4 is completed, turn the limit nut 9 to press against the bottom of the movable guide plate 4. At the same time, slide and adjust the height of the guide driving mechanism 5, that is, the support plate 51 slides along the guide rod 3 so that the support plate 51 is located at the middle position between the fixed guide plate 2 and the movable guide plate 4. After the position adjustment of the support plate 51 is completed, turn the limit nut 9 so that the limit nut 9 presses against the clamping plate 52 below. Secondly, when loading the long screw, the first guide chute 6 guides and slides the lower end of the long screw, and the second guide chute 7 guides and slides the upper end of the long screw. The middle part of the long screw is caught in the positioning groove 8 of the synchronous belt 55. Finally, the driving motor 54 rotates to drive the belt pulley 53 to rotate, and the belt pulley 53 rotates to drive the synchronous belt 55 to run. The side surface of the support plate 51 has a stable supporting effect on the movement of the synchronous belt 55, so that the synchronous belt 55 drives the long screw to move smoothly.
