Description

Technical Field

[0001] This utility model relates to the field of bolt cleaning technology, specifically a tool for cleaning dirt and grime from the thread grooves of bolts. Background Technology

[0002] A bolt is a mechanical part, mainly composed of a head and a thread. It needs to be used with a nut to fasten two parts with through holes. This type of connection is called a bolted connection, which is a detachable connection. As an important component of mechanical connection, bolts can be repaired and reused from old bolts on ball mill liners in order to save material costs. The thread grooves of old bolts often accumulate dirt, oil and other impurities. These impurities not only affect the fastening effect of the bolts, but may also cause damage or corrosion to the bolts, thereby affecting the stability and safety of the entire equipment.

[0003] Current methods for repairing and reusing old bolts typically involve welding and machining. However, the old bolts still require manual fixation to remove the dirt and grime from their threads. They are then cleaned with a wire brush. This method is not only time-consuming and labor-intensive but also inefficient. It is difficult to completely remove stubborn dirt and grease, leaving potential hazards. Furthermore, when using tools to clean old bolts, they need to be clamped and fixed, which can easily cause them to tilt. This requires manual support and adjustment, affecting the efficiency of subsequent cleaning. Utility Model Content

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-4 As shown, a tool for cleaning dirt from bolt thread grooves includes a workbench 1. A first clamping plate 2 is mounted on the top of the workbench 1, and a second clamping plate 3 is fixed to the top of the workbench 1. The workbench 1 facilitates support for the first clamping plate 2 and the second clamping plate 3. It should be noted that the first clamping plate 2, driven by a transmission mechanism inside the workbench 1, can move the first clamping plate 2 and the second clamping plate 3 to fix the bolt body 5. It should also be noted that the inner walls of both the first clamping plate 2 and the second clamping plate 3 have grooves, which make the device more securely fix the bolt body 5. The inner wall of the second clamping plate 3 is provided with two sets of limiting mechanisms 4. These two symmetrically designed limiting mechanisms 4 can limit the bolt body 5 before fixing it, preventing the bolt body 5 from being fixed. Before fixing, the bolt body 5 is tilted. The bolt body 5 is set above the workbench 1. The inner wall of the bolt body 5 is threaded with a nut 6. The inner wall of the nut 6 has a groove 7. When the nut 6 moves downward when the bolt body 5 is threaded, the thread grooves of the bolt body 5 and the nut 6 fit together, so that the dirt in the thread grooves of the bolt body 5 can be discharged from the groove 7. Two sets of snap-fit ​​mechanisms 8 are symmetrically arranged on the outer side of the nut 6. Two sets of handles 9 are arranged on the outer side of the nut 6. The two sets of handles 9 are fixed to the outer side of the nut 6 by the two sets of snap-fit ​​mechanisms 8. The snap-fit ​​mechanism 8 can connect the handles 9 to the nut 6, so that the device can replace the nut 6 according to the bolt body 5 of the body size.

[0023] The limiting mechanism 4 includes two sets of fixing blocks 41 fixed to the inner wall of the second clamping plate 3. The inner walls of the two sets of fixing blocks 41 are slidably connected to sliding rods 42. A spring 43 is fixed to one side of each set of fixing blocks 41. A clamping block 44 is fixed to one end of the sliding rod 42, and one side of the clamping block 44 is fixedly connected to one end of the spring 43. The fixing blocks 41 can limit the sliding rod 42 sliding on its inner wall and fix one end of the spring 43. The sliding rod 42 can support the clamping block 44. The spring 43 can drive the clamping block 44 to be related to the bolt body 5 through the reverse force, thus avoiding the bolt body 5 from tilting before fixing.

[0024] The snap-fit ​​mechanism 8 includes two sets of threaded joints 81 fixed to the outside of the nut 6, and the inner wall of the threaded joint 81 is provided with a groove. The outer sides of the two sets of threaded joints 81 are threadedly connected with snap-fit ​​blocks 82. The two sets of threaded joints 81 are configured so that the snap-fit ​​blocks 82 can rotate on their outer threads, causing the threaded joints 81 to retract from the groove, thereby fixing the handle 9 to both sides of the nut 6.

[0025] A handle 10 is threaded onto the inner wall of the handle 9, and a protective sleeve 11 is provided on the outer side of the handle 10. The protective sleeve 11 is made of polyurethane. The handle 10 increases the length of the handle 9, making it easier for workers to work. At the same time, the polyurethane material of the protective sleeve 11 makes the handle 10 fit the hand better, increasing friction and thus preventing slippage. The inner wall of the workbench 1 has two sets of sliding grooves 12, and the inner walls of both sets of sliding grooves 12 are slidably connected to sliders 13, and the top of the sliders 13 is fixedly connected to the bottom of the first clamping plate 2. The inner wall of the workbench 1 is rotatably connected to a horizontally arranged... A threaded rod 14 has a turntable 15 fixed to one end. A movable block 16 is fixed to the bottom of the first clamping plate 2, and the inner wall of the movable block 16 is rotatably connected to the outer side of the threaded rod 14. The sliding groove 12 can limit the sliding block 13 that slides on its inner wall. Since the sliding block 13 is fixedly connected to the first clamping plate 2, it can limit the first clamping plate 2. The threaded rod 14 can drive the movable block 16 to move. Since the movable block 16 is fixed to the first clamping plate 2 with a bolt, it can drive the first clamping plate 2 to fix the bolt body 5. The turntable 15 can drive the threaded rod 14 to rotate.

[0026] Working principle: In use, first pull the two sets of sliding rods 42 outwards. The two sets of sliding rods 42 drive the clamping blocks 44 to move outwards. Then, place the bolt body 5 between the two sets of clamping blocks 44. After that, release the sliding rods 42. The clamping blocks 44 will clamp the bolt body 5 through the reverse force of the spring 43. Then, rotate the turntable 15. The turntable 15 drives the threaded rod 14 to rotate. The threaded rod 14 drives the movable block 16 to move. The movable block 16 drives the first clamping plate 2 to fix the bolt body 5. Then, tighten the locking block 82 to make the threaded rod 6 match the bolt body 5. The connector 81 retracts, thereby locking the handle 9 onto the outside of the nut 6. Then, the handle 10, along with the protective sleeve 11, is installed at one end of the handle 9. The handle 10 is then rotated, causing the nut 6 to move along the outside of the bolt body 5. Since the thread groove of the nut 6 and the thread groove of the bolt body 5 are mutually engaged, the dirt in the thread groove of the bolt body 5 can be discharged from the inclined groove 7. After cleaning the upper part of the bolt body 5, the bolt body 5 is turned around, and the clamped part of the bolt body 5 is cleaned in the same way, thereby completing the purpose of cleaning the bolt body 5.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
