Technical Field

[0002] Mechanical parts are the basic components of machinery. There are many materials for making 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 forming of mechanical parts requires multiple processing steps, such as cutting, and cutting requires the use of cutting devices.

Therefore, handheld grinders are needed for cutting and grinding. During cutting, it is easy to have uneven cutting surfaces and jagged edges. This is because during the cutting process, factors such as cutting speed, cutting angle and stability of the cutting tool are difficult to keep constant, 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.

DETAILED DESCRIPTION
[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.
[0025] Reference Figure 1-Figure 7 A flexible structure feeding cutting and grinding integrated machine comprises a base 1, on which a fixture rotation driving mechanism 2 is arranged, and a driving end of the fixture rotation driving mechanism 2 is provided with a workpiece fixture 3 located on the side of the base 1, and a support shaft 4 is installed on the top of the base 1, and a cantilever 5 is rotatably installed on the outer side of the support shaft 4, and a first horizontal moving mechanism 6 is installed on one side of the cantilever 5, and a lifting driving device 7 is installed on the driving end of the first horizontal moving mechanism 6, and the lifting driving device 7 can adopt a hydraulic cylinder, a cylinder or a push rod motor, and a second horizontal moving device 8 is installed on the driving end of the lifting driving device 7, and the driving end of the second horizontal moving device 8 is connected to the cutting and grinding driving mechanism 9 through a buffer structure, and a cutting and grinding disc 10 is installed on the driving end of the cutting and grinding driving mechanism 9, and the cutting and grinding disc 10 is a grinding wheel.
[0026] This device integrates the existing grinding and cutting design with a buffer structure. When in use, the workpiece is first placed on the workpiece fixture 3, and the cutting and grinding process of the workpiece by the cutting and grinding disk 10 is realized through the coordinated use of 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 (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 the cutting and reduce damage to the cutting tool (if the hardness of the product is extremely high, the cutting tool is easily damaged without adding a buffer structure).
[0027] 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 through a rotating shaft, and a first spring assembly is installed at the other end of the mounting frame 12, and the other end of the first spring assembly is connected to the mounting seat 11, and the cutting and grinding drive mechanism 9 is installed below the mounting frame 12;
[0028] The first spring assembly includes a connecting rod 13 fixedly mounted on the side of the mounting frame 12 and a first spring 14 , wherein 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 .
[0029] The implementation process of the above buffer structure is as follows: when impacted by a force, the mounting frame 12 rotates with the corresponding rotating shaft as a base point to compress the first spring 14 and the second spring 17 to achieve buffering.
[0030] In this embodiment, an elastic adjustment component and a second spring component are provided on the side of the interior of the mounting seat 11. 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, and a first slider 19 that penetrates the first slider 19 and is connected to the first slider 19 by a thread A connected threaded rod 20, a 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, a first connecting block 22 installed on the outside of the first slider 19, and a 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 actual working conditions.
[0031] 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 rotating drive motor 25 installed on the support 24, a turntable 26 installed at the driving end of the rotating drive motor 25, and a power rod 27 rotatably connected to one side of the surface of the turntable 26 through a rotating shaft, and 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 inner cavity at the bottom 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 rotating 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 front and back cutting and grinding the workpiece surface.
[0032] 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, for achieving the balance of the entire device and the cantilever 5, which is not shown in the figure.
[0033] In this embodiment, the workpiece clamp 3 includes a turntable installed on the driving end of the clamp rotation drive mechanism 2, an adjustment slot opened on the outside of the turntable and a clamping block arranged inside the adjustment slot. 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.
[0034] 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, and a pulley installed on one side of the cutting and grinding disc 10 / clamp rotates through a belt transmission, 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 on 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.
