Description

Technical Field

[0001] The present invention relates to the field of grinding machines, and more particularly to an efficient grinding machine for the production of steel structure parts Background Art Steel structure is a structure with the highest degree of industrialization. Steel structures are usually used to replace traditional concrete, brick, and wood structures because steel has higher strength, stiffness, wind resistance, and seismic resistance. In addition, due to the construction and design capabilities of steel, longer spans and heights can be achieved, which means that buildings can be taller and larger and provide a more modern design. As people's living standards continue to improve, the use of steel structures in our daily lives is becoming more and more frequent. Among them, steel structure components are an integral part of steel structures. During the production and processing of steel structure parts, a grinding machine tool is required to grind the surface and welding joints of the steel structure parts to improve the roughness and quality of the steel structure part surface and ensure the stability and safety of the subsequent use of the steel structure part

[0002] According to the published patent CN117140299A, an efficient grinding machine tool for the production of steel structure parts includes a machine tool housing. A first one-way threaded rod is threadedly connected to the machine tool housing. An end of the first one-way threaded rod is rotatably connected to a mounting plate. A limiting rod is fixedly connected to the mounting plate. The limiting rod passes through and is slidably connected to a side end of the machine tool housing. An adaptive grinding assembly is mounted on the mounting plate. A web and a flange plate are connected to the adaptive grinding assembly. The web is welded to the flange plate. A dust removal assembly is mounted on the top of the machine tool housing. An ultrasonic flaw detector is mounted on the machine tool housing. A connecting cable is connected to the ultrasonic flaw detector

[0003] In the process of implementing the invention, the inventor found that at least the following problems in the prior art have not been solved. Through the air pump on the collection box and the suction heads on each connecting pipe in the above case, the dust and debris generated by grinding can be efficiently and stably sucked. The two-way threaded rod can drive the fixed frames threadedly connected on both sides to move towards the middle or both sides at the same time, and thus the steel structure parts can be conveniently and stably clamped and positioned. However, during the use process, the dust generated by the grinding disc will spread, and the suction heads are far from the grinding disc. In this way, the negative pressure generated by the suction heads cannot effectively suck the dust, affecting the dust removal effect. Moreover, it is necessary for the staff to manually rotate the threaded rod to push the two groups of fixed frames to clamp the steel component. After the steel component is clamped, the staff also needs to rotate the threaded rod in the reverse direction to release the clamping of the fixed frame on the steel component. The labor intensity of the staff is large and the work efficiency is affected

[0004] Therefore, a new technical solution needs to be designed to solve this problem Summary of the Invention

[0010] As a preferred solution of the present invention, a dust suction pipe is penetrated and fixedly installed on the rear side of the upper surface of the mounting plate, and the suction end of the dust suction pipe is communicated with the dust suction holes.

[0011] As a preferred solution of the present invention, the driving mechanism includes two groups of racks and a gear.

Connecting grooves are vertically and symmetrically opened at both ends of the upper surface of the grinding table. The two groups of racks are respectively vertically welded on both sides of the bottom surface of the electric slide rail. The two groups of racks on the bottom surface of the electric slide rail are respectively slidably connected with the two groups of connecting grooves on the upper surface of the grinding table. A compensation plate is arranged on the side of the clamping block close to the rack. The compensation plate is slidably connected with the upper surface of the grinding table. A threaded sleeve is horizontally and fixedly installed on the side of the compensation plate far from the clamping block. A threaded rod is spirally connected inside the threaded sleeve. One end of the threaded rod placed inside the connecting groove is fixedly connected to the middle of the gear.

[0012] As a preferred solution of the present invention, the threaded rod is rotatably connected with the connecting groove through a bearing, and the thread directions of the threaded rods on both sides of the grinding table are opposite.

[0013] As a preferred solution of the present invention, a spring is provided between the compensation plate and the clamping block.

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-4 The technical solutions provided by the present invention specifically include the following embodiments: Embodiment: An efficient grinding machine for the production of steel structure parts includes a grinding table 1. Above the grinding table 1, there is a grinding motor 11. The shaft end of the grinding motor 11 is detachably installed with a grinding disc 12. Above the grinding table 1, there is an adjustment structure for adjusting the grinding disc 12. The adjustment structure includes an electric slide rail 15 and two electro-hydraulic push rods 17. The outer side of the electric slide rail 15 is slidably connected with a sliding sleeve 14. The bottom end of the sliding sleeve 14 is horizontally welded with a mounting plate 13. The grinding motor 11 is fixedly connected to the middle of the bottom side of the mounting plate 13. The telescopic ends of the two electro-hydraulic push rods 17 are respectively fixedly connected to the two ends of the bottom side of the electric slide rail 15. On both sides of the grinding table 1, support plates 16 are symmetrically installed. The ends of the two electro-hydraulic push rods 17 away from the electric slide rail 15 are respectively fixedly connected to the upper surfaces of the two support plates 16.

[0024] By controlling the electric slide rail 15 to work through the corresponding controller, the mounting plate 13 can be driven to move left and right under the electric slide rail 15 through the sliding sleeve 14, so as to drive the grinding disc 12 on the bottom side of the mounting plate 13 to move left and right, and adjust the grinding position of the steel structure member on the upper surface of the grinding table 1. Controlling the two electro-hydraulic push rods 17 to work synchronously can drive the electric slide rail 15 to move up and down above the grinding table 1, so as to adjust the use height of the grinding disc 12 according to the size of the steel structure member. Controlling the grinding motor 11 to work can drive the grinding disc 12 to rotate, and effectively grind the steel structure member on the upper surface of the grinding table 1, which is convenient and fast.

[0025] A dust collection mechanism is provided on the outer side of the grinding disc 12. The dust collection mechanism includes a dust collection hood 2 covering the outer side of the grinding disc 12 and dust collection holes 21 equidistantly distributed on the inner wall of the dust collection hood 2. On both sides of the upper surface of the dust collection hood 2, limiting rods 23 are vertically and fixedly installed. Through holes are vertically formed through both sides of the upper surface of the mounting plate 13, and the limiting rods 23 are slidably connected to the through holes. The dust collection hood 2 is dimensionally matched with the grinding disc 12. At the rear side of the upper surface of the mounting plate 13, a dust collection pipe 22 is penetrated and fixedly installed. The suction end of the dust collection pipe 22 is communicated with the dust collection holes 21.

[0026] By means of the sliding connection between the limiting rods 23 and the through holes, the installation stability of the dust collection hood 2 can be improved. At the same time, the dust collection hood 2 can slide on the outer side of the grinding disc 12. During the process of the grinding disc 12 grinding the steel member, the bottom end of the dust collection hood 2 can abut against the upper surface of the steel member and cover the outer side of the grinding disc 12, which can protect the grinding disc 12 and prevent sparks and debris from splashing during the grinding process of the grinding disc 12 and causing harm to the staff. At the same time, through the dust collection holes 21 equidistantly distributed on the inner wall of the dust collection hood 2, the dust collection pipe 22 can effectively clean the dust generated by the grinding of the grinding disc 12 inside the dust collection hood 2 and avoid the diffusion of the dust, which affects the cleaning effect. It should be noted that the dust collection pipe 22 is communicated with the dust suction port of the corresponding dust collector, and the dust collector is controlled to work to generate negative pressure in the dust collection holes 21 for dust collection operation.

[0027] On both sides of the upper surface of the grinding table 1, clamping blocks 3 are symmetrically arranged. It also includes a driving mechanism for driving the clamping blocks 3 to move. The driving mechanism includes two groups of racks 41 and a gear 43. The racks 41 are meshed with the gear 43, and the racks 41 are dimensionally matched with the gear 43. The grinding table 1 is U-shaped. At both ends of the upper surface of the grinding table 1, connecting grooves 4 are vertically and symmetrically formed. The two groups of racks 41 are respectively vertically welded on both sides of the lower surface of the electric slide rail 15. The two groups of racks 41 on the lower surface of the electric slide rail 15 are respectively slidably connected to the two groups of connecting grooves 4 on the upper surface of the grinding table 1. On the side of the clamping block 3 close to the rack 41, a compensation plate 31 is provided. The compensation plate 31 is slidably connected to the upper surface of the grinding table 1. On the side of the compensation plate 31 away from the clamping block 3, a threaded sleeve 32 is horizontally and fixedly installed. A threaded rod 42 is spirally connected inside the threaded sleeve 32. One end of the threaded rod 42 placed inside the connecting groove 4 is fixedly connected to the middle of the gear 43.

[0028] When the grinding disc 12 at the bottom side of the electro-hydraulic push rod 17 drives the electro-hydraulic push rod 17 to move downward, it can simultaneously push the two groups of racks 41 to slide in the two groups of connecting grooves 4 on the upper surface of the grinding table 1. Through the engagement of the rack 41 and the gear 43, during the downward movement of the rack 41, it can drive the gear 43 to rotate, thereby driving the threaded rod 42 to rotate. Since the threaded rod 42 is rotationally connected to the threaded sleeve 32, during the rotation of the threaded rod 42, it can push the two groups of compensation plates 31 and the two groups of clamping blocks 3 connected to the threaded sleeve 32 to move relatively. Through the linkage method, during the process of grinding the steel member, the steel member can be automatically clamped, with high working efficiency. On the contrary, when the steel member on the upper surface of the grinding table 1 is polished, control the electro-hydraulic push rod 17 to drive the electric slide rail 15 to move upward, so that the grinding disc 12 at the bottom side of the mounting plate 13 is far away from the steel member. At the same time, the electric slide rail 15 drives the two groups of racks 41 to move upward, thereby driving the two groups of gears 43 to rotate in the reverse direction. Further, the threaded rod 42 can drive the two groups of compensation plates 31 to move in the reverse direction through the threaded sleeve 32, thereby pulling the two groups of clamping blocks 3 to move in the reverse direction and reset, further automatically releasing the clamping of the clamping block 3 on the steel member, facilitating the staff to quickly collect the polished steel member, with a high degree of automation.

[0029] The threaded rod 42 is rotationally connected to the connecting groove 4 through a bearing, and the thread directions of the threaded rods 42 on both sides of the grinding table 1 are opposite.

[0030] During the up and down movement of the two groups of racks 41, they can simultaneously drive the two groups of gears 43 to rotate synchronously, further driving the threaded rods 42 in the middle of the two groups of gears 43 to rotate synchronously. Due to the opposite thread directions of the threaded rods 42 on both sides of the grinding table 1, during the synchronous rotation of the two groups of threaded rods 42, through the threaded sleeve 32, the two groups of clamping blocks 3 can be driven to move relatively or in the reverse direction, further realizing the clamping operation of the clamping block 3 on the steel member on the upper surface of the grinding table 1.

[0031] A spring 34 is arranged between the compensation plate 31 and the clamping block 3. At the front and rear ends of the side of the clamping block 3 close to the compensation plate 31, a compensation rod 33 is horizontally and fixedly installed. The compensation rod 33 horizontally penetrates the compensation plate 31 and is slidably connected to the compensation plate 31. The spring 34 is sleeved on the outside of the compensation rod 33. On the side of the clamping block 3 away from the compensation plate 31, a fixing groove 35 is provided, and the fixing groove 35 is in an inverted V shape.

[0032] As the grinding disc 12 grinds the surface of the steel member, the thickness of the steel member will decrease. In order to continue to control the grinding of the steel member by the grinding disc 12, it is necessary to control the electro-hydraulic push rod 17 to drive the grinding disc 12 to move downward continuously, so that the grinding disc 12 is closely attached to the upper surface of the steel member to continue the grinding operation. In this way, the electric slide rail 15 will push the rack 41 to move downward continuously, thereby driving the threaded rod 42 to rotate, and continue to push the two sets of compensation plates 31 to move relatively through the threaded sleeve 32. By providing a spring 34 between the compensation plate 31 and the clamping block 3, it can be avoided that when the clamping block 3 clamps the steel member, the compensation plate 31 cannot move, thus affecting the adjustment of the grinding height of the grinding disc 12 by the electro-hydraulic push rod 17. By providing an inverted V-shaped fixing groove 35 on the side of the clamping block 3 away from the compensation plate 31, the special-shaped steel member can be clamped. It should be noted that the dimensions of the threaded rod 42, the gear 43 and the rack 41 need to be designed according to the dimensions of the steel member to ensure that when the electro-hydraulic push rod 17 pushes the grinding disc 12 at the bottom side of the mounting plate 13 to grind the steel member, the displacement of the rack 41 can drive the gear 43 and the threaded rod 42 to rotate, so that the threaded sleeve 32 pushes the compensation plate 31 and the clamping block 3 to clamp both sides of the steel member.

[0033] Working principle: Place the steel component to be polished on the upper surface of the polishing table 1 and between two sets of clamping blocks 3. Control the electric slide rail 15 to work through the corresponding controller. The sliding sleeve 14 can drive the mounting plate 13 to move left and right on the bottom side of the electric slide rail 15, thereby driving the grinding disc 12 on the bottom side of the mounting plate 13 to move left and right, and adjusting the polishing position of the steel component on the upper surface of the polishing table 1. Control the two electro-hydraulic push rods 17 to work synchronously, which can drive the electric slide rail 15 to move up and down above the polishing table 1, so as to adjust the use height of the grinding disc 12 according to the size of the steel component. When the electro-hydraulic push rod 17 drives the grinding disc 12 on the bottom side of the electric slide rail 15 to move downward, it can simultaneously push the two racks 41 to slide in the two connecting grooves 4 on the upper surface of the polishing table 1. Through the engagement of the rack 41 and the gear 43, during the downward movement of the rack 41, it can drive the gear 43 to rotate, thereby driving the threaded rod 42 to rotate. Through the rotational connection of the threaded rod 42 and the threaded sleeve 32, during the rotation of the threaded rod 42, it can push the two compensation plates 31 and the two clamping blocks 3 connected to the threaded sleeve 32 to move relatively, and automatically clamp the steel component during the polishing process of the steel component in a linkage manner. Control the polishing motor 11 to work, which can drive the grinding disc 12 to rotate, and effectively polish the steel component on the upper surface of the polishing table 1. Through the sliding connection of the limiting rod 23 and the limiting groove 24, the installation stability of the dust suction hood 2 can be improved. At the same time, the dust suction hood 2 can slide outside the grinding disc 12. During the polishing process of the grinding disc 12 on the steel component, the bottom end of the dust suction hood 2 can abut against the upper surface of the steel component and cover the outside of the grinding disc 12, which can protect the grinding disc 12 and prevent the sparks and debris generated during the grinding of the grinding disc 12 from splashing and causing harm to the staff. At the same time, the dust suction pipe 22 can effectively clean the dust generated by the grinding of the grinding disc 12 inside the dust suction hood 2 through the dust suction holes 21 equidistantly distributed on the inner wall of the dust suction hood 2, avoiding the diffusion of dust and affecting the cleaning effect. As the grinding disc 12 polishes the surface of the steel component, the thickness of the steel component will decrease. In order to continue to control the grinding disc 12 to polish the steel component, it is necessary to control the electro-hydraulic push rod 17 to drive the grinding disc 12 to move downward continuously, so that the grinding disc 12 is closely attached to the upper surface of the steel component and continues to perform the polishing operation. By arranging a spring 34 between the compensation plate 31 and the clamping block 3, it can prevent the compensation plate 31 from being unable to move when the clamping block 3 clamps the steel component. Control the electric slide rail 15 to drive the two racks 41 to move upward, thereby driving the two gears 43 to rotate in the reverse direction. Further, the threaded rod 42 can drive the two compensation plates 31 to move in the reverse direction through the threaded sleeve 32, thereby pulling the two clamping blocks 3 to move in the reverse direction and reset, further automatically releasing the clamping of the clamping block 3 on the steel component, which is convenient for the staff to quickly collect the polished steel component.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
