The existing screws also have burrs on the surface after processing, affecting subsequent use and making it inconvenient to quickly clean the screws. Therefore, we propose a new device to solve the above problems. Utility Model Content

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: an adjustable length screw thread rolling machine, comprising a main housing, a movable motor sleeved inside the main housing, a movable lead screw inserted at one end of the movable motor, a movable block slidably connected inside the main housing, a mating plate inserted on one side of the movable block, a movable hydraulic rod sleeved on one side of the mating plate, a main rolling plate inserted at one end of the movable hydraulic rod, a secondary rolling plate sleeved on one side of the main housing, a lubrication assembly sleeved on one side of the main housing, a grinding assembly installed inside the main housing, a main observation plate rotatably connected inside the main housing, a mating spring inside the main observation plate, a mating rod inserted at one end of the mating spring, a secondary observation plate rotatably connected inside the main housing, a fixing spring inside the secondary observation plate, a fixing rod inserted at one end of the fixing spring.

[0006] Optionally, the lubrication assembly includes a lubrication box, a lubrication cover plate, a water pump, a bamboo tube, and a nozzle. The lubrication cover plate is installed on the upper surface of the lubrication box, and a water pump is sleeved inside the lubrication box. One end of the water pump is sleeved with a bamboo tube, and one end of the bamboo tube is inserted with a nozzle.

[0007] Optionally, the upper surface of the lubrication cover is threaded with fixing bolts, and the lubrication cover is threaded with a lubrication box through the fixing bolts, wherein the number of fixing bolts is two.

[0008] Optionally, the grinding assembly includes a grinding base, a feed hopper, a rotary motor, a grinding cylinder, a discharge pipe, and a collection box. The feed hopper is sleeved on the upper surface of the grinding base, the rotary motor is sleeved inside the grinding base, one end of the rotary motor is inserted into the grinding cylinder, the discharge pipe is sleeved inside the grinding base, and the collection box is slidably connected inside the grinding base.

[0009] Optionally, the surface of the grinding cylinder is provided with multiple holes, and a limiting rod is sleeved on one side of the grinding seat to limit the collection box. The number of limiting rods is two.

[0010] Optionally, a threaded hole is provided on one side of the movable block, and the movable lead screw passes through the threaded hole to move the movable block within the main housing.

[0011] Optionally, a cleaning box is slidably connected inside the main housing, and a limiting rod is sleeved on one side of the main housing to limit the cleaning box. There are two limiting rods. An ultrasonic plate is installed inside the cleaning box, and a stirring motor is sleeved inside the cleaning box. A stirring shaft is inserted into one end of the stirring motor.

[0012] Optionally, a base is installed at the lower part of the main housing, a main cover plate is installed on the upper surface of the main housing, and multiple limiting holes are opened on one side of the main housing.

[0013] In summary, the technical effects and advantages of this utility model are as follows: 1. This utility model has a reasonable structure. Unprocessed screws are placed into the equipment via an external feeding device. The main and auxiliary washing plates clamp the screws. A moving motor drives a moving screw to rotate, causing the screw to move a moving block within the main housing. The moving block, in turn, moves a moving hydraulic rod and the main washing plate to perform the thread-rolling operation on the screws. The distance between the main and auxiliary washing plates is adjusted by moving the main washing plate via a moving hydraulic rod on one side of the mating plate, achieving convenient and quick thread-rolling of screws of different sizes. The simple and flexible operation improves thread rolling efficiency, thus reducing the limitations of the equipment's limited applicability and its inability to meet diverse needs. Lubricating oil is added to the lubrication tank through the water inlet pipe on the upper surface of the lubrication cover plate. A water pump extracts the lubricating oil from the tank and sprays it onto the screw surface through a nozzle. The nozzle position is adjusted via a bamboo-joint tube, enabling convenient and quick application of lubricating oil to unprocessed screws. The ease of nozzle position adjustment reduces the risk of screw breakage during thread rolling due to lack of lubrication during machining.

[0014] 2. In this utility model, the processed screws fall into the grinding cylinder through the feed hopper at the top of the grinding base. A rotary motor rotates the grinding cylinder, removing burrs from the screw surface. The burrs fall into a collection box through holes in the grinding cylinder surface, and then into a cleaning box through a discharge pipe. When the collection box is full, the limiting rod on one side of the grinding base is removed, the collection box is taken out, emptied, and then put back. This achieves convenient and quick removal of screw burrs, facilitating subsequent cleaning and use, saving significant manpower and resources. It also reduces the risk of burrs being difficult to collect, which could potentially reduce the grinding effect. By pouring cleaning solution into the cleaning box, the stirring motor drives the stirring shaft to rotate, dispersing the screws inside for cleaning. Ultrasonic vibrations then perform deep cleaning on the screws, achieving convenient and quick screw cleaning with a more thorough finish. This reduces the risk of a large number of screws being concentrated together, which could reduce the cleaning effect. By removing the limiting rod on one side of the main body, the cleaning box can be taken out, and the cleaned screws can be removed. Pulling the connecting rod compresses the connecting spring, opening the main observation plate for observation and adjustment. Pulling the fixing rod compresses the fixing spring, opening the secondary observation plate for observation and adjustment. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example: Reference Figures 1-8 The adjustable length screw thread rolling machine shown includes a main housing 1. A movable motor 2 is sleeved inside the main housing 1. A movable screw 3 is inserted into one end of the movable motor 2. A movable block 4 is slidably connected inside the main housing 1. A docking plate 5 is inserted into one side of the movable block 4. A movable hydraulic rod 6 is sleeved into one side of the docking plate 5. A main rolling plate 7 is inserted into one end of the movable hydraulic rod 6. A secondary rolling plate 8 is sleeved into one side of the main housing 1. A lubrication assembly 9 is sleeved into one side of the main housing 1. A grinding assembly 10 is installed inside the main housing 1. A main observation plate 11 is rotatably connected inside the main housing 1. A docking spring 12 is provided inside the main observation plate 11. A docking rod 13 is inserted into one end of the docking spring 12. A secondary observation plate 14 is rotatably connected inside the main housing 1. A fixing spring 15 is provided inside the secondary observation plate 14. A fixing rod 16 is inserted into one end of the fixing spring 15.

[0019] As a preferred embodiment of this example, Figures 1 to 5 As shown, a moving motor 2 is sleeved inside the main housing 1. A moving screw 3 is inserted into one end of the moving motor 2. A moving block 4 is slidably connected inside the main housing 1. A threaded hole is opened on one side of the moving block 4, through which the moving screw 3 passes, allowing the moving block 4 to move within the main housing 1. A docking plate 5 is inserted into one side of the moving block 4. A moving hydraulic rod 6 is sleeved on one side of the docking plate 5. A main washboard 7 is inserted into one end of the moving hydraulic rod 6. A secondary washboard 8 is sleeved on one side of the main housing 1. A lubrication assembly 9 is sleeved on one side of the main housing 1. The lubrication assembly 9 includes a lubrication box 901, a lubrication cover plate 902, and water. The system includes a pump 903, a bamboo-joint tube 904, and a nozzle 905. A lubrication cover 902 is mounted on the upper surface of the lubrication box 901. Two fixing bolts are threaded through the upper surface of the lubrication cover 902 and threaded through the lubrication box 901. A water pump 903 is fitted inside the lubrication box 901. A bamboo-joint tube 904 is fitted to one end of the water pump 903, and a nozzle 905 is inserted into the other end of the bamboo-joint tube 904. A base 21 is mounted on the lower part of the main box 1, and a main cover 22 is mounted on the upper surface of the main box 1. During use, materials are fed in from the outside. The equipment places unprocessed screws into the machine, where they are clamped by the main thread-rolling plate 7 and the auxiliary thread-rolling plate 8. A moving motor 2 drives a moving screw 3, which in turn moves a moving block 4 within the main housing 1. The moving block 4 then moves a moving hydraulic rod 6 and the main thread-rolling plate 7 to perform the thread-rolling operation. The distance between the main thread-rolling plate 7 and the auxiliary thread-rolling plate 8 is adjusted by moving the moving hydraulic rod 6 on one side of the mating plate 5, allowing for convenient and quick thread-rolling of screws of different sizes. The operation is simple and flexible, improving thread-rolling efficiency. This reduces the problem of the equipment being too limited in its application range and unable to meet different needs. Lubricating oil is added to the lubrication tank 901 through the water inlet pipe on the upper surface of the lubrication cover plate 902. The lubricating oil in the lubrication tank 901 is extracted by the water pump 903 and sprayed onto the surface of the screw through the nozzle 905. The position of the nozzle 905 is adjusted by the bamboo tube 904, which makes it convenient and quick to spray lubricating oil onto the unprocessed screws. The position of the nozzle 905 can be easily adjusted, thereby reducing the possibility of damage to the screws during thread rolling due to lack of lubricating oil when the screws are being processed.

[0020] like Figures 5 to 8As shown, in this embodiment, a grinding assembly 10 is installed inside the main housing 1. The grinding assembly 10 includes a grinding base 101, a feed hopper 102, a rotary motor 103, a grinding cylinder 104, a discharge pipe 105, and a collection box 106. The feed hopper 102 is sleeved on the upper surface of the grinding base 101. The rotary motor 103 is sleeved inside the grinding base 101. One end of the rotary motor 103 is inserted into the grinding cylinder 104. Multiple holes are opened on the surface of the grinding cylinder 104. The discharge pipe 105 is sleeved inside the grinding base 101. The collection box 106 is slidably connected inside the grinding base 101. A limiting rod is sleeved on one side of the grinding base 101, and the limiting rod limits the collection box 106. There are two limiting rods. The main observation plate 11 is rotatably connected inside the main body 1. A docking spring 12 is installed inside the main observation plate 11, and a docking rod 13 is inserted into one end of the docking spring 12. A secondary observation plate 14 is rotatably connected inside the main body 1. A fixing spring 15 is installed inside the secondary observation plate 14, and a fixing rod 16 is inserted into one end of the fixing spring 15. A cleaning box 17 is slidably connected inside the main body 1. Two limit rods are fitted onto one side of the main body 1 to limit the movement of the cleaning box 17. An ultrasonic transducer 18 is installed inside the cleaning box 17. A stirring motor 19 is fitted inside the cleaning box 17, and a stirring shaft 20 is inserted into one end of the stirring motor 19. Multiple limit holes are opened on one side of the main body 1 for use. During the process, the processed screws fall into the grinding cylinder 104 through the feed hopper 102 at the top of the grinding base 101. The rotating motor 103 drives the grinding cylinder 104 to rotate, removing burrs from the screw surface. The burrs fall into the collection box 106 through holes in the surface of the grinding cylinder 104, and then the screws fall into the cleaning box 17 through the discharge pipe 105. When the collection box 106 is full, the limiting rod on one side of the grinding base 101 is removed, the collection box 106 is taken out, emptied, and then put back. This achieves convenient and quick removal of burrs from the screws, facilitating subsequent cleaning and use, saving a lot of manpower and resources, and reducing the difficulty of collecting removed burrs, which could reduce grinding efficiency. The effect is that by pouring cleaning solution into the cleaning box 17, the stirring motor 19 drives the stirring shaft 20 to rotate, which disperses the screws in the cleaning box 17 for cleaning. The ultrasonic plate 18 vibrates to deeply clean the screws, achieving convenient and quick screw cleaning, and cleaning more thoroughly. This reduces the possibility of a large number of screws being concentrated together, which may reduce the cleaning effect. By removing the limiting rod on one side of the main box 1, the cleaning box 17 can be taken out and the cleaned screws can be taken out. By pulling the docking rod 13 to compress the docking spring 12, the main observation plate 11 can be opened for observation and adjustment. By pulling the fixing rod 16 to compress the fixing spring 15, the secondary observation plate 14 can be opened for observation and adjustment.

[0021] The working principle of this practical application is as follows: During operation, unprocessed screws are fed into the equipment via external feeding equipment. The main and auxiliary screw plates 7 and 8 clamp the screws. A moving motor 2 drives a moving screw 3, which in turn moves a moving block 4 within the main housing 1. The moving block 4 then moves a moving hydraulic rod 6 and the main screw plate 7 to perform the thread-rolling operation on the unprocessed screws. The moving hydraulic rod 6 on one side of the mating plate 5 moves the main screw plate 7 to adjust the distance between the main and auxiliary screw plates 7 and 8. Lubricating oil is added to the lubrication tank 901 through the water inlet pipe on the upper surface of the lubrication cover plate 902. A water pump 903 extracts the lubricating oil from the lubrication tank 901 and sprays it onto the screw surface through a nozzle 905. The position of the nozzle 905 is adjusted via a bamboo-joint tube 904. The processed screws fall into the grinding cylinder 104 through the feed hopper 102 on the upper part of the grinding base 101. The screws are then rotated by a rotating motor 1. 03. The grinding cylinder 104 is rotated to remove burrs from the surface of the screws. The burrs fall into the collection box 106 through the holes on the surface of the grinding cylinder 104. The screws fall into the cleaning box 17 through the discharge pipe 105. When the collection box 106 is full, the limiting rod on one side of the grinding seat 101 is removed, the collection box 106 is taken out, emptied, and then put back. Cleaning liquid is poured into the cleaning box 17. The stirring motor 19 drives the stirring shaft 20 to rotate, which disperses the screws in the cleaning box 17 for cleaning. The screws are deeply cleaned by the vibration of the ultrasonic plate 18. The limiting rod on one side of the main box 1 is removed, the cleaning box 17 is taken out, and the cleaned screws are taken out. The connecting rod 13 is pulled to compress the connecting spring 12, and the main observation plate 11 is opened for observation and adjustment. The fixing rod 16 is pulled to compress the fixing spring 15, and the secondary observation plate 14 is opened for observation and adjustment.
