Description

Technical Field

[0001] The utility model 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] During the assembly process of large turntables, the contact surface between the turntable and the swivel seat requires scraping and lapping by fitters to ensure rotational stability and accuracy. Scraping and lapping is a combination of scraping and lapping. The fitter uses a scraper to scrape the surface, and lapping reveals the contact surface's lapping state. These two processes are performed in tandem. Lapping involves dyeing the workpiece with a dye, and lapping the tool and workpiece to reveal the scraping quality. Lapping provides a basis for judging the quality of the previous scraping step and indicating the next scraping area.

[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. Utility Model Content

[0005] In order to achieve the above-mentioned purpose, the present utility model adopts the following technical solutions.

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

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

[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] The beneficial effects of the utility model.

[0011] The utility model uses a lifting machine as a power source, utilizes a lifting device to pass through a drum frame, causes the drum to rotate around a fixed axis, changes the dragging direction, thereby realizing the combined use of the lifting machine and the lifting device, solves the waste of manpower and material resources caused by relying entirely on manpower to drag the combined development of a large turntable, and improves 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 with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0013] Figure 1 It is a three-dimensional structural diagram of the utility model.

[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 both 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-fitted, 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] During use, use anchor bolts to pass through the light hole 5 at the bottom of the bracket 1. According to the use conditions of 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 roller 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 roller 4 and is tied to the hanging screw. In this way, the large turntable is dragged using 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 implementation methods of the present invention. Ordinary technicians in this field 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 scope of protection of the present invention.
