Description

Technical Field

[0001] The utility model relates to the technical field of cutting and polishing devices, and in particular to a buffer mechanism applied to a cutting and polishing all-in-one machine. Background Art

[0002] Mechanical parts are the basic components of machinery. There are many materials used to make mechanical parts, which can be divided into metal materials and non-metallic materials. Metal materials include cast iron, steel, cast steel, copper alloy, etc., while non-metallic materials include rubber, plastic, etc. The molding of mechanical parts requires multiple processing steps, such as cutting, and cutting requires the use of cutting devices.

[0003] For example, products such as large shaft seats and large pump casings need to be cut during the processing. However, since their materials are generally high-chromium cast iron, high-chromium alloy and other materials with extremely high hardness, and they are large in size and complex in shape, hand-held grinders are generally used for cutting and grinding. However, it is easy for the cutting surface to be uneven and the edges to be jagged during cutting. This is because factors such as the cutting speed, cutting angle and stability of the cutting tool are difficult to maintain constant during the cutting process, and the adjustment of the position of heavy products is also difficult to operate. Therefore, the quality of cutting and grinding depends on manual experience. If these products are cut with an automatic cutting machine, the tool may be damaged due to the excessive hardness of the product.

[0004] Therefore, those skilled in the art provide a buffer mechanism applied to a cutting and grinding machine to solve the problems raised in the above background technology. Utility Model Content

The lifting drive device 7 can adopt a hydraulic cylinder, an air cylinder or a push rod motor. The driving end of the lifting drive device 7 is installed with a second horizontal moving device 8, and the driving end of the second horizontal moving device 8 is connected to the cutting and grinding mechanism through this buffer structure, and the cutting and grinding mechanism includes a cutting and grinding drive mechanism 9, and the driving end of the cutting and grinding drive mechanism 9 is installed with a cutting and grinding disc 10, which is a grinding wheel.

[0023] When using this buffer structure, the workpiece is first placed on the workpiece fixture 3, and the cutting and grinding disk 10 is used in coordination with the first horizontal moving mechanism 6, the lifting drive device 7, the second horizontal moving device 8 and the cutting and grinding drive mechanism 9 to realize the cutting process of the workpiece (the cutting and grinding disk 10 cuts the periphery and grinds the side after cutting). In this process, the buffer structure can effectively absorb the vibration generated during the cutting process, so that the cutting tool maintains a stable cutting trajectory and makes the grinding pressure more stable, thereby improving the accuracy of the cutting size and reducing the roughness of the cutting surface. It can also absorb the impact force generated by cutting and reduce damage to the cutting tool (if the hardness of the product is extremely high, it is easy to damage the cutting tool without adding a buffer structure).

[0024] In this embodiment, the buffer structure includes a mounting seat 11 installed at the driving end of the second horizontal moving device 8 and a mounting frame 12 rotatably connected to one side of the mounting seat 11 via a rotating shaft. The other end of the mounting frame 12 is installed with a first spring assembly, and the other end of the first spring assembly is connected to the mounting seat 11. The cutting and grinding drive mechanism 9 is installed below the mounting frame 12.

[0025] The first spring assembly includes a connecting rod 13 fixedly mounted on the side of the mounting frame 12 and a first spring 14 . The bottom end of the first spring 14 is connected to the other end of the connecting rod 13 , and the top end of the first spring 14 is connected to the side end of the mounting seat 11 .

[0026] The implementation process of the above buffer structure is as follows: when subjected to a force impact, the mounting bracket 12 rotates around the corresponding rotation axis as a base point to compress the first spring 14 and the second spring 17 to achieve buffering.

[0027] In this embodiment, the side of the interior of the mounting seat 11 is provided with an elastic adjustment component and a second spring component, the second spring component includes a rotating seat 15 installed on the side of the mounting frame 12, a support rod 16 rotatably connected to the rotating seat 15 through a rotating shaft, and a second spring 17, the bottom end of the second spring 17 is connected to the other end of the support rod 16, and the top end of the second spring 17 is connected to the side end of the mounting seat 11, the elastic adjustment component includes a first slide rail 18 installed on the top side of the interior of the mounting seat 11, a first slider 19 slidably connected to the first slide rail 18, a first slider 19 that passes through the first slider 19 and is connected to the first slider 19 by a thread The connected threaded rod 20, the rotating wheel 21 installed at one end of the threaded rod 20 and rotatably connected to the side of the mounting seat 11 through a bearing, the first connecting block 22 installed on the outside of the first slider 19, and the second connecting block 23 rotatably connected to the first connecting block 22 through a rotating shaft, the second connecting block 23 is slidably sleeved on the outside of the support rod 16, and the threaded rod 20 can be rotated by rotating the rotating wheel 21, so that the first slider 19 moves outside the threaded rod 20, thereby driving the second connecting block 23 to move outside the support rod 16, so that the vertical distance between the mounting seat 11 and the mounting frame 12 can be adjusted, and the adjustment can be adjusted according to the actual working conditions.

[0028] In this embodiment, the second horizontal moving device 8 includes a support 24 arranged at the driving end of the lifting drive device 7, a rotary drive motor 25 installed on the support 24, a turntable 26 installed at the driving end of the rotary drive motor 25, and a power rod 27 rotatably connected to one side of the surface of the turntable 26 through a rotating shaft. The other end of the power rod 27 is rotatably connected to the top of the mounting seat 11 through a rotating shaft. Second slide rails 28 are installed on both sides of the bottom inner cavity of the support 24, and second sliders 29 are installed on both sides of the mounting seat 11. The second sliders 29 are slidably arranged on the corresponding second slide rails 28. When the rotary drive motor 25 is started, the turntable 26 rotates, and then reciprocating motion is realized through the power rod 27 to complete the reciprocating process of cutting and polishing the workpiece surface.

[0029] In this embodiment, a counterweight is installed on the other side of the cantilever 5. The counterweight is located on the other side of the support shaft 4, that is, the relative position of the cantilever 5, and is used to achieve the balance of the entire device and the cantilever 5.

The clamping block is screwed into the adjustment slot by bolts, and the workpiece is placed between several clamping blocks, and the workpiece is fixed by tightening the clamping blocks.

[0031] In this embodiment, the cutting and grinding drive mechanism 9 and the clamp rotation drive mechanism 2 both adopt a belt-driven rotation method (that is, a rotating motor drives a pulley, which is driven by a belt to rotate the pulley installed on one side of the cutting and grinding disc 10 / clamp, thereby driving the cutting and grinding disc 10 / clamp to rotate), and the first horizontal moving mechanism 6 can adopt an electric slide or directly insert the lifting drive device 7 into the cantilever 5 (that is, the first horizontal mechanism is a slot opened on the cantilever 5), and use gravity and friction to adjust its position on the cantilever 5.
