Description
Technical Field
[0001] This utility model relates to the technical field of steel grinding equipment, and more specifically, to a steel grinding machine device. Background Technology
[0002] As a core force in steel structure construction, the riveting and welding team in the machine repair workshop shoulders the heavy responsibility of constructing various steel structure projects. Within their complex and crucial work scope, the grinding and rust removal processes of steel occupy a pivotal position, serving as the foundation for ensuring the quality of subsequent construction. The quality of these two processes, whether they achieve a flawless surface and uniform treatment, directly affects the success or failure of the final painting process of the steel structure project. A smooth surface formed after grinding is a prerequisite for ensuring even paint adhesion; while thorough rust removal prevents rust from damaging the paint surface, providing a stable base for painting.
[0003] A grinding machine is a manual power tool used for grinding metal surfaces. Existing grinding machines, when grinding steel pipes, rely solely on manual control. This makes it prone to slippage between the grinding disc and the pipe surface, hindering manual grinding and making it difficult to control the grinding depth. Furthermore, the efficiency is low. Inadequate grinding can result in uneven surfaces, rust residue, or incomplete rust removal, leading to uneven paint application. This uneven painting not only detracts from the smoothness and luster of the steel structure, causing defects such as patchy spots and noticeable color differences, but also indirectly affects the overall quality and professional impression, negatively impacting the final project presentation. Therefore, for welding teams, meticulous, thorough, and uniform grinding and rust removal are crucial for ensuring the quality of the steel structure's appearance. Utility Model Content

[0014] Figure 1 This is a schematic diagram of the overall structure of the present invention. Figure 2 This is a schematic diagram of the specific structure of the clamping mechanism of this utility model. Detailed Implementation
[0015] The present invention will be further described below with reference to specific embodiments.
[0016] A steel grinding machine device includes a grinding machine body 1. A horizontal plate 2 is fixedly connected to the lower surface of the grinding machine body 1. The horizontal plate has a clearance hole for the rotation shaft of the grinding machine body 1 to pass through. A grinding brush connected to the rotation shaft of the grinding machine body 1 is located below the horizontal plate 1. Vertical plates 3 are fixedly connected to both ends of the horizontal plate 2. An adjustment mechanism 4 is provided at the lower end of each of the two vertical plates 3. A clamping mechanism 5 is provided at the inner end of each of the two adjustment mechanisms 4. The clamping mechanism clamps a guide wheel 6.
[0017] In use, the workpiece is placed between the two guide wheels 6, and the guide wheels 6 are brought into contact with the workpiece through the adjusting mechanism 4. The clamping mechanism 5 securely clamps the guide wheels 6, ensuring that they do not shift during grinding. At this point, the grinding brush can contact the workpiece. Then, the grinding machine body 1 is started, and its rotating shaft drives the grinding brush to rotate at high speed, efficiently grinding the workpiece placed between the two guide wheels 6. The adjusting mechanism 4 can be flexibly adjusted according to the actual size of the workpiece, ensuring that the guide wheels 6 and the workpiece always maintain close contact, thereby improving the grinding accuracy and effect. Compared with handheld grinding machine 1, it can effectively reduce the errors and instabilities caused by manual operation, improve the stability and consistency of grinding quality, significantly improve production efficiency, and reduce production costs.
[0018] In a preferred embodiment, the adjusting mechanism 4 includes a through hole 41 at the lower end of the vertical plate 3, through which a threaded rod 42 passes. Two locking bolts 43 are threaded onto the threaded rod 42, located on the inner and outer sides of the vertical plate 3 respectively. The inner ends of the two threaded rods 42 are connected to the clamping mechanism 5. In actual operation, when it is necessary to adjust the position of the clamping mechanism 5 to accommodate workpieces of different sizes, simply rotate the adjusting cap 44 to rotate the threaded rod 42. Since the two locking bolts 43 are located on the inner and outer sides of the vertical plate 3 and are threaded onto the threaded rod 42... Next, by tightening and loosening the locking bolts 43, the threaded rod 42 can be easily moved back and forth in the through hole 41, thereby driving the clamping mechanism 5 connected to the inner end of the threaded rod 42 to move. When the clamping mechanism 5 moves to the appropriate position, so that the guide wheel 6 is in close contact with the workpiece, the two locking bolts 43 are tightened to make it fit tightly against the vertical plate 3, thereby fixing the threaded rod 42 on the vertical plate 3. This ensures that the position of the clamping mechanism 5 and the guide wheel 6 is stable during the grinding process and will not be displaced due to the vibration generated by grinding, thereby ensuring that the grinding work can be carried out continuously, stably and accurately.
[0019] In a preferred embodiment, an adjusting cap 44 is fixedly connected to the outer end of the threaded rod 42. The surface of the adjusting cap 44 may be provided with anti-slip texture. When the operator rotates the adjusting cap 44, it can effectively increase the friction between the hand and the adjusting cap 44, avoiding slippage and making the rotation operation easier and more precise. This, in turn, makes it easier to drive the threaded rod 42 to rotate, thereby adjusting the position of the clamping mechanism 5. Moreover, the adjusting cap 44 is made of high-strength plastic material. This material is not only lightweight and easy for the operator to hold, but also has a certain degree of toughness and is not easily damaged. It can maintain good performance during long-term use and extend the service life of the entire adjusting mechanism 4.
[0020] In a preferred embodiment, the clamping mechanism 5 includes U-shaped clamping pieces 51 fixedly connected to the inner end of the threaded rod 42. The open sections of the two U-shaped clamping pieces 51 are arranged opposite each other. The guide wheel 6 is disposed inside the U-shaped clamping pieces 51. A locking bolt 52 passes through the center hole of the guide wheel 6 through the U-shaped clamping pieces 51. Both ends of the locking bolt 52 are fastened with nuts. This design ensures that the guide wheel 6 is securely clamped between the two U-shaped clamping pieces 51. During the grinding process, the guide wheel 6 remains stable with the clamping mechanism 5 and will not wobble or shift. Furthermore, the U-shaped clamping pieces 51 can be made of high-quality alloy steel, which has high strength and hardness. It is not easily deformed when subjected to the large forces generated during the grinding process, and can continuously provide reliable support for the guide wheel 6, ensuring the normal operation of the grinding work. At the same time, the locking bolt 52 can also undergo a special heat treatment process, resulting in high surface hardness and strong wear resistance. It is not easily worn during frequent friction with the center hole of the guide wheel 6, further ensuring the stability and durability of the entire clamping structure 5.
[0021] In a preferred embodiment, shims 53 are provided between the upper and lower sides of the guide wheel 6 and the U-shaped clamp 51. These shims 53 are made of highly elastic rubber. On the one hand, they can effectively buffer the vibration of the guide wheel 6 during the grinding process, reduce the damage to the guide wheel 6 and the clamping mechanism 5 caused by the vibration, and extend the service life of the equipment. On the other hand, the shims 53 can fill the small gap between the guide wheel 6 and the U-shaped clamp 51, making the contact between the guide wheel 6 and the U-shaped clamp 51 tighter, further enhancing the stability of the guide wheel 6 in the clamping mechanism 5, and preventing the guide wheel 6 from loosening when it is running at high speed or subjected to large external forces, thereby ensuring the accuracy and quality of the grinding work.
[0022] In a preferred embodiment, the vertical plate 3 is divided into an outer plate 31 and an inner plate 32. An opening 33 is formed at the lower end of the outer plate 31, and the inner plate 32 is slidably connected within the opening 33. The outer plate 31 and the inner plate 32 are connected by a fixing structure 7. An adjustment mechanism 4 is located at the lower end of the inner plate 32, facilitating disassembly and adjustment of the inner plate 32's position within the opening 33. The adjustment mechanism 4 allows operators to precisely adjust the inner plate 32 according to actual polishing needs, thereby changing parameters such as the height or angle of the entire vertical plate 3 to better adapt to different polishing scenarios and improve the flexibility and efficiency of the polishing work.
[0023] In a preferred embodiment, the fixing structure 7 includes a fixing threaded hole 71 on the outer plate 31, with a fixing bolt 72 internally threaded into the fixing threaded hole 71. This design makes the connection between the outer plate 31 and the inner plate 32 both stable and easy to disassemble. When it is necessary to adjust the height or angle of the vertical plate 3 according to different grinding requirements, simply loosen the fixing bolt 72, move the inner plate 32 to the appropriate position, and then retighten the fixing bolt 72 to fix the inner plate 32, which greatly improves the applicability and ease of operation of the equipment. The cooperation between the adjusting mechanism 4 and the clamping mechanism 5 enables the device to adapt to steel workpieces of different sizes and specifications, greatly improving its versatility and flexibility.
[0024] In a preferred embodiment, a base 8 is fixedly connected to the upper end of the grinder body 1. A fixing frame 81 is provided above the base 8. The two sides of the fixing frame 81 are rotatably connected to the base 8. A sleeve 82 with an upward opening is fixedly connected to the upper surface of the fixing frame 81. A handle 83 is detachably fixedly connected inside the sleeve 82. Preferably, the sleeve (82) and the handle (83) are disassembled and assembled by a pin, so that the handle 83 can be flexibly replaced according to actual usage needs. When the handle 83 is damaged or different types and sizes of handles 83 are needed to adapt to different operating habits and grinding scenarios, simply pull out the pin, take the old handle 83 out of the sleeve 82, insert the new handle 83 into the sleeve 82, and fix it with the pin. This greatly improves the convenience and flexibility of using the grinder. Meanwhile, the design of the fixed frame 81 being rotatably connected to the base 8 allows the fixed frame 81 to rotate at a certain angle relative to the base 8, thereby driving the sleeve 82 and the handle 83 to rotate. The operator can adjust the angle of the handle 83 according to their own operating posture and comfort to obtain a better operating experience and further improve the efficiency and quality of the grinding work.
