Description

Technical Field

[0001] This application relates to the field of grinding machine tool technology, and more specifically, to a multi-segment circular arc convexity grinding machine that facilitates material loading. Background Technology

[0002] Multi-segment arc convexity grinding is a precision machining process that uses a CNC grinding machine or special grinding equipment to clamp the workpiece and process its surface to form a convex profile composed of multiple arc segments of different radii.

[0003] In related technologies, for example, the prior art patent with publication number CN212794523U provides a loading mechanism for a multi-segment arc convexity grinding machine. This device places the bearing rings on a guide plate, and the bearing rings move downwards under their own gravity. When they move into the positioning gap between the blocking member and the positioning member, the driving member drives the blocking member and the positioning member to move downwards to complete the loading of the bearing rings. When the blocking member moves downwards into the drop channel, the distance between the blocking member and the guide plate is less than the length of the workpiece, so the bearing rings cannot enter the drop gap. After loading is completed, the driving member retracts, allowing the bearing rings close to the blocking member to enter the positioning gap between the blocking member and the positioning member. This process is repeated to achieve loading of the bearing rings one by one, thereby improving the loading efficiency of the bearing rings.

[0004] Although the existing technical solutions described above have solved the problems in the background art, when grinding bearing rings, it is often necessary to fix the bearing rings with a fixture and then grind them with a grinding mechanism. After the bearing rings are loaded, they cannot fall into the clamping end of the fixture, which is not convenient for subsequent clamping of the bearing rings.

[0005] In view of this, we propose a multi-segment circular arc convexity grinding machine that is easy to load. Utility Model Content

[0038] The present application will be further described in detail below with reference to the accompanying drawings.

[0039] Reference Figure 1 , Figure 2 , Figure 4 , Figure 7 and Figure 8 This application discloses a multi-segment arc convexity grinding machine for easy loading, including a grinding assembly 1. A clamp 2 is provided on the inner side of the grinding assembly 1 for clamping the bearing ring body 100. A loading assembly 3 is provided on the inner side of the grinding assembly 1, located on one side of the clamp 2. The loading assembly 3 includes a fixed side plate 31 and a movable side plate 32. A guide plate 33 and a limiting plate 34 are fixedly provided on the side of the fixed side plate 31 and the movable side plate 32 that are close to each other. The guide plate 33 and the limiting plate 34 are arranged in a V-shape to support and limit the bearing ring body 100. A movable seat 311 is fixedly provided at the bottom of the fixed side plate 31. The movable seat 311 is driven to rise and fall by external force to drive the bearing ring body 100 to be concentrically aligned with the clamp 2. The movable seat 311 is also driven to move horizontally by external force to drive the bearing ring body 100 closer to the clamp 2.

[0040] After the feeding assembly 3 feeds the bearing ring body 100, the bearing ring body 100 falls between the guide plate 33 and the limiting plate 34. Since the guide plate 33 and the limiting plate 34 are arranged in a V shape, the centers of the bearing ring bodies 100 of different diameters are on the same vertical line when they are located between the guide plate 33 and the limiting plate 34. By driving the moving seat 311 with external force, the height of the moving seat 311 is adjusted, thereby adjusting the height of the fixed side plate 31 and the moving side plate 32, thereby adjusting the height of the guide plate 33 and the limiting plate 34, so that the bearing ring body 100 is concentrically set with the clamp 2, which facilitates the subsequent clamping of the bearing ring body 100 by the clamp 2.

[0041] After the bearing ring body 100 is concentric with the clamp 2, the fixed side plate 31 and the movable side plate 32 are moved by external force, thereby driving the bearing ring body 100 to move closer to the clamp 2, so that the clamp 2 can clamp the bearing ring body 100. Then, the bearing ring body 100 is ground in multiple arc convexity by the grinding assembly 1. The grinding assembly 1 and the clamp 2 are existing technology equipment. The clamp 2 is a three-jaw chuck, which is mainly used to clamp workpieces with symmetrical shapes such as cylinders, rings, and equilateral triangles.

[0042] Reference Figure 6 , Figure 7 , Figure 8 and Figure 9 The outer sides of the fixed side plate 31 and the movable side plate 32 are provided with machining ports 38 corresponding to the grinding assembly 1 and the fixture 2. A drive assembly 4 is provided on the outer side of the movable seat 311 to drive its movement. The drive assembly 4 includes two electric push rods B41 for driving the movable seat 311 to move vertically. The electric push rods B41 are fixedly mounted on the outer side of the fixed frame 42. The output end of the electric push rods B41 is connected to the movable seat 311 through an adjusting assembly A44. The adjusting assembly A44 is used to drive the movable seat 311 to move horizontally. The adjusting assembly A44 includes an electric push rod C441. A mounting bracket is fixedly mounted on the outer side of the fixed frame 42. Mounting plate 43, electric push rod C441 is fixedly installed inside the mounting plate 43, the output end of electric push rod C441 is fixedly installed on the outside of movable seat 311, the adjustment component A44 also includes two slide rails 442, two sliders A3111 are fixedly installed at the bottom of movable seat 311, sliders A3111 are slidably installed with the corresponding slide rails 442, the output end of electric push rod B41 is fixedly installed with the bottom of slide rail 442, slider B4421 is fixedly installed on the outside of slide rail 442, and grooves 421 are opened on both sides of the fixing frame 42 corresponding to slider B4421, slider B4421 is slidably installed with grooves 421.

[0043] After the bearing ring body 100 is fed, the bearing ring body 100 falls between the guide plate 33 and the limiting plate 34. The slide rail 442 is driven to rise and fall by the electric push rod B41, which in turn drives the slider A3111 to rise and fall. The slider A3111 drives the moving seat 311 to rise and fall. Adjusting the height of the moving seat 311 adjusts the height of the bearing ring body 100, so that the bearing ring body 100 and the clamp 2 are concentrically set, which makes it easier for the clamp 2 to clamp the bearing ring body 100. The slider B4421 slides inside the slide groove 421 to limit the rising and falling movement of the moving seat 311.

[0044] After the bearing ring body 100 is concentric with the clamp 2, the moving seat 311 is driven to move by the electric push rod C441, thereby driving the fixed side plate 31 and the moving side plate 32 to move, thereby driving the bearing ring body 100 to move closer to the clamp 2, so that the clamp 2 can clamp the bearing ring body 100. Then, the bearing ring body 100 is ground with multi-segment arc convexity by the grinding assembly 1, wherein the slider A3111 slides inside the slide rail 442 to limit the horizontal movement of the moving seat 311.

[0045] Reference Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 and Figure 10A support plate 35 is fixedly installed on the side of the fixed side plate 31 and the movable side plate 32 that are close to each other. A sliding plate 36 is slidably installed on the bottom of the support plate 35. A sliding opening 361 is opened on the outer side of the sliding plate 36 on the outer side of the movable side plate 32. A sliding block 362 is fixedly installed on the inner side of the sliding plate 36 on the outer side of the fixed side plate 31. The sliding opening 361 and the sliding block 362 are slidably installed. A moving groove 37 is opened on the outer side of the fixed side plate 31 and the movable side plate 32 corresponding to the sliding plate 36. A connecting piece 363 is fixedly installed on the side of the sliding block 362 away from the movable side plate 32. The connecting piece 363 is fixedly installed on the electric push rod A3. At the output end of 64, the electric push rod A364 is fixedly installed on the outside of the fixed side plate 31. An adjustment component B5 is provided on the side of the fixed side plate 31 near the movable side plate 32 for driving the movable side plate 32 to move. The adjustment component B5 includes a sliding column 51, which is fixedly installed on the side of the fixed side plate 31 near the movable side plate 32. The movable side plate 32 is slidably installed on the outside of the sliding column 51. A fixed plate 53 is fixedly installed on the outside of the fixed side plate 31 through the housing 54. An electric push rod D52 is fixedly installed on the outside of the fixed plate 53. The output end of the electric push rod D52 is fixedly installed on the outside of the movable side plate 32.

[0046] When feeding the bearing ring body 100, the bearing ring body 100 is placed into the support plate 35 through the feed port on the outside of the outer shell 54. The bearing ring body 100 moves along the support plate 35 and the sliding plate 36 to the top of the guide plate 33. The connecting piece 363 is moved by the electric push rod A364, which drives the sliding block 362 to slide inside the moving groove 37. The sliding block 362 drives the two sliding plates 36 to slide, so that the two sliding plates 36 move away from the guide plate 33. This allows the bearing ring body 100 to fall from the gap between the guide plate 33 and the sliding plate 36, achieving the effect of feeding the bearing ring body 100 one by one.

[0047] When feeding bearing ring bodies 100 of different thicknesses, the moving side plate 32 is driven to move by the electric push rod D52. The moving side plate 32 slides outside the sliding column 51, adjusting the distance between the fixed side plate 31 and the moving side plate 32, thus adapting to bearing ring bodies 100 of different thicknesses.

[0048] In summary, when using the multi-segment arc convexity grinding machine disclosed in this application embodiment, the bearing ring body 100 is placed onto the support plate 35 through the feed port on the outside of the housing 54. The bearing ring body 100 moves along the support plate 35 and the sliding plate 36 to the top of the guide plate 33. The connecting piece 363 is moved by the electric push rod A364, thereby causing the sliding block 362 to slide inside the moving groove 37. The sliding block 362 causes the two sliding plates 36 to slide, moving the two sliding plates 36 away from the guide plate 33. This allows the bearing ring body 100 to fall from the gap between the guide plate 33 and the sliding plate 36, achieving the effect of feeding the bearing ring body 100 one by one.

[0049] The bearing ring body 100 rests between the guide plate 33 and the limiting plate 34. Since the guide plate 33 and the limiting plate 34 are arranged in a V-shape, the centers of the bearing ring bodies 100 of different diameters are on the same vertical line when they are located between the guide plate 33 and the limiting plate 34. The slide rail 442 is driven to rise and fall by the electric push rod B41, which in turn drives the slider A3111 to rise and fall. The slider A3111 drives the moving seat 311 to rise and fall. Adjusting the height of the moving seat 311 adjusts the height of the bearing ring body 100, so that the bearing ring body 100 is concentrically set with the clamp 2, which facilitates the subsequent clamping of the bearing ring body 100 by the clamp 2.

[0050] After the bearing ring body 100 is concentric with the clamp 2, the moving seat 311 is driven to move by the electric push rod C441, thereby driving the fixed side plate 31 and the moving side plate 32 to move, thereby driving the bearing ring body 100 to move closer to the clamp 2, so that the clamp 2 can clamp the bearing ring body 100. Then, the bearing ring body 100 is ground with multi-segment arc convexity by the grinding assembly 1.
