Description

Technical Field

[0001] The invention belongs to the technical field of mechanical processing tools, and in particular relates to a large-scale rotary table scraping and grinding device. Background Art

[0002] In the assembly process of large turntables, in order to ensure the rotation stability and rotation accuracy of large turntables, the contact surface between the turntable and the swivel seat needs to be scraped and ground by fitters. Scraping and grinding is a combination of scraping and grinding. The fitter uses a scraper to scrape the plane, and the grinding shows the contact surface grinding state. The two processes are carried out in coordination. The grinding is the process of using a display agent to dye the workpiece, and the grinding tool and the workpiece are ground to show the scraping quality. The grinding provides a basis for judging the scraping quality of the previous step and showing the scraping area of ​​the next step.

[0003] Usually, when scraping and grinding small parts, the fitter can push the grinding tool and the workpiece to grind. However, large turntables are heavy and difficult to push entirely by manpower. This causes inconvenience to the grinding work, increases the scraping and grinding process time, reduces assembly efficiency, and relies entirely on manpower, resulting in a waste of manpower and material resources. Summary of the invention

[0004] The present invention is aimed at the above-mentioned problems, makes up for the deficiencies of the prior art, and provides a large-scale turntable scraping and grinding device; the present invention can use a lifting machine as a power source, solve the waste of manpower and material resources caused by relying entirely on manpower to drag the large-scale turntable for grinding, and improve the assembly efficiency of the large-scale turntable.

[0005] To achieve the above purpose, the present invention adopts the following technical solution.

[0006] The present invention provides a large-scale turntable scraping and grinding device, comprising a bracket, characterized in that a roller frame is connected to the top surface of the bracket, the bracket and the roller frame are both welded parts, and are welded together using tubular steel and plate steel. A fixed shaft is fixed on the roller frame, a rotatable roller is sleeved on the outside of the fixed shaft, and a plurality of light holes are arranged at the bottom of the bracket.

[0007] Furthermore, the fixed shaft is fixedly connected to the roller frame via a top screw.

[0008] Furthermore, the fixed shaft and the roller are clearance-fitted.

[0009] Furthermore, the roller frame is detachably connected to the bracket via screws and washers.

[0010] Beneficial effects of the present invention.

[0011] The present invention uses a lifting machine as a power source and utilizes a lifting device to pass through a drum frame, so that the drum rotates around a fixed axis and changes the dragging direction, thereby realizing the combined use of the lifting machine and the lifting device, solving the waste of manpower and material resources caused by completely relying on manpower to drag a large turntable for combined research, and improving the assembly efficiency of the large turntable. BRIEF DESCRIPTION OF THE DRAWINGS

[0012] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described herein are only used to explain the present invention and are not used to limit the present invention.

[0013] Figure 1 It is a three-dimensional structural schematic diagram of the present invention.

[0014] Markings in the figure: 1 is the bracket, 2 is the roller frame, 3 is the fixed shaft, 4 is the roller, 5 is the light hole, 6 is the screw, 7 is the washer, and 8 is the top screw. DETAILED DESCRIPTION

[0015] As shown in the accompanying drawings, this embodiment provides a large-scale turntable scraping and grinding device, including a bracket 1, a roller frame 2 is connected to the top surface of the bracket 1, and the roller frame 2 is detachably connected to the bracket 1 through screws 6 and washers 7.

[0016] The bracket 1 and the roller frame 2 are both welded parts, and are welded together by using tubular steel and plate steel.

[0017] A fixed shaft 3 is fixed on the roller frame 2, and the fixed shaft 3 is fixedly connected to the roller frame 2 through a top screw 8. The fixed shaft 3 cannot rotate. A rotatable roller 4 is sleeved on the outside of the fixed shaft 3. The fixed shaft 3 and the roller 4 are clearance-matched, and the roller 4 can rotate around the fixed shaft 3.

[0018] A plurality of light holes 5 are provided at the bottom of the bracket 1 .

[0019] When in use, use anchor bolts to pass through the light holes 5 at the bottom of the bracket 1. According to different use conditions at different positions and heights, use different numbers of washers (depending on the height requirements) to fix the bracket 1 on the ground rail, so that the horizontal height of the drum 4 is slightly lower than the hanging screw. The hanging screw is placed on the large turntable, one end of the lifting rope is hung on the hook, and the other end passes through the drum 4 and is tied to the hanging screw. The large turntable is then dragged by lifting machinery and lifting equipment to complete the joint research.

[0020] It can be understood that the above specific description of the present invention is only used to illustrate the present invention and is not limited to the technical solutions described in the embodiments of the present invention. Those skilled in the art should understand that the present invention can still be modified or replaced by equivalents to achieve the same technical effects; as long as the use requirements are met, they are within the protection scope of the present invention.
