Description
Technical Field
[0001] This utility model relates to the technical field of integrated grinding and cutting machines, and in particular to a multifunctional small precision integrated grinding and cutting machine. Background Technology
[0002] The grinding machine is used to grind the workpiece, and the cutting machine is used to cut the workpiece. The two devices are relatively independent, and it is inconvenient to switch back and forth during use. In addition, two sets of electrical equipment are used, which increases the cost of use.
[0003] A Chinese patent for a multi-functional grinding and cutting machine (CN214351675U) was found. This patent technology includes a main structure, which comprises a grinding and cutting chamber, a front seat, and a rear seat. The grinding and cutting chamber is connected to the front seat and the rear seat respectively. The grinding and cutting chamber is equipped with a drive motor and a support frame. The front seat is equipped with a second adjusting valve and a fixed plate connected to the grinding and cutting chamber. The front seat includes front wheels located on both sides of the bottom of the front seat and an auxiliary wheel fixing frame located on one side of the front seat. The auxiliary wheel fixing frame is equipped with auxiliary wheels. The rear seat is equipped with a first adjusting valve, a control mechanism, and rear wheels located on both sides of the bottom of the rear seat. This utility model achieves multi-angle transformation through adjusting holes, thereby enabling the grinding and cutting components to perform both grinding and cutting functions, greatly improving the practicality and novelty of this utility model.
[0004] This patented technology simultaneously drives grinding and cutting during use. However, when the grinding or cutting structure is in use, the other set of equipment will run idle, which increases the load on the motor. The idle structure is prone to accidental activation, posing a safety hazard. To address this, we propose a multi-functional small precision grinding and cutting integrated machine to solve the existing problems. Utility Model Content
[0005] The purpose of this invention is to address the problems existing in the background technology by proposing a multifunctional small precision grinding and cutting integrated machine.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a multifunctional small precision grinding and cutting integrated machine, comprising a central cylinder, a connecting pipe, a first rotating shaft, a second rotating shaft, a mounting shaft, and a motor. The connecting pipe is connected to both ends of the central cylinder. The mounting shaft is provided with symmetrically distributed mounting shafts inside the connecting pipe. The motor is provided inside the central cylinder. A bevel gear is provided at the output end of the motor. A bevel gear is provided at one end of each mounting shaft, meshing with the first bevel gear. A docking seat is provided at one end of each mounting shaft. The first rotating shaft and the second rotating shaft are respectively provided inside the connecting pipe. A docking seat is provided at one end of both the first rotating shaft and the second rotating shaft. A grinding wheel is provided at one end of the first rotating shaft, and a cutting wheel is provided at one end of the second rotating shaft.
[0007] Preferably, the first docking seat has a docking groove arranged in a ring array at one end, and the second docking seat has a docking pin arranged in a ring array at one end. The outer wall of the docking pin and the inner wall of the docking groove are both provided with corresponding arc surfaces. The first docking seat connects with the docking pin of the second docking seat through the docking groove. During the docking process, the arc surfaces guide the docking process.
[0008] Preferably, each connecting pipe is equipped with a bearing bracket inside, and the mounting shaft is rotatably mounted inside the bearing bracket. The bearing bracket provides rotational support for the mounting shaft, which is thus supported within the connecting pipe.
[0009] Preferably, a mounting sleeve is fitted onto the outer side of the first and second rotating shafts, and a travel rod is provided at the upper end of the mounting sleeve. The mounting sleeve rotates outside the first and second rotating shafts, and moves by gripping the travel rod.
[0010] Preferably, the upper end of the connecting pipe has a travel groove, and the travel rod is slidably installed inside the travel groove. The travel rod slides inside the connecting pipe through the travel groove, allowing the travel rod to move within the upper end of the connecting pipe.
[0011] Preferably, a support block is provided on the outer wall of the connecting pipe, a sliding sleeve is embedded inside the support block, a positioning rod is slidably inserted inside the sliding sleeve, and the upper end of the travel rod has symmetrically distributed positioning holes that slidably engage with the positioning rod. The support block and the sliding sleeve provide slidable support for the positioning rod, which is inserted into the stationary positioning hole to position the moved mounting sleeve.
[0012] Preferably, a limiting ring is sleeved on the outer wall of the positioning rod, and a spring is sleeved on the outside of the positioning rod between the limiting ring and the support block. A pull ring is provided at the upper end of the positioning rod. The elastic force of the spring acts on the positioning rod through the limiting ring, so that when the pull ring is gripped and moves the positioning ring, the spring supports the positioning rod, and the positioning rod is effectively fixed inside the positioning hole.
[0013] Preferably, both the first and second rotating shafts are fitted with mounting rings rotatably mounted inside the mounting sleeve. The outer wall of each mounting ring is rotatably mounted with a ring-shaped array of first-type balls, and both ends of the mounting ring are rotatably mounted with ring-shaped second-type balls. The mounting ring rolls against the inner wall of the mounting sleeve via the first and second-type balls. As the mounting ring rotates with the first and second rotating shafts, it reduces frictional resistance with the mounting sleeve. The movement of the mounting sleeve then drives the first and second rotating shafts to move.
[0014] Preferably, the lower end of the mounting sleeve is disposed on the slider, and the inner wall of the lower end of the connecting tube is provided with a guide rail that is slidably mounted to the slider. The slider supports the lower end of the mounting sleeve, and the mounting sleeve is laterally guided by the slider sliding on the outer wall of the guide rail.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] 1. The motor of this utility model drives two mounting shafts to rotate through bevel gear one and bevel gear two. When the mounting shafts rotate, shaft one and shaft two are connected to the mounting shafts through docking seats one and two. After docking, the rotational force is transmitted, so that shaft one drives the grinding wheel to rotate to grind the workpiece, and shaft two drives the cutting wheel to rotate to cut the workpiece. During use, the two sets of equipment are avoided from working at the same time, avoiding idling and reducing the motor load during use. At the same time, the equipment avoids the safety hazards of accidental activation when the equipment is idling. Moreover, the overall structure of the equipment is small and compact, easy to use, and realizes multi-functional use. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] like Figures 1-5 As shown, the present invention proposes a multifunctional small precision grinding and cutting integrated machine, including a central cylinder 1, a connecting pipe 2, a rotating shaft 7, a rotating shaft 8, a mounting shaft 11, and a motor 13. The connecting pipe 2 is connected to both ends of the central cylinder 1. The mounting shafts 11 are symmetrically distributed inside the connecting pipe 2. The motor 13 is installed inside the central cylinder 1. A bevel gear 14 is installed at the output end of the motor 13. A bevel gear 15 that meshes with the bevel gear 14 is installed at one end of each mounting shaft 11. A docking seat 16 is installed at one end of each mounting shaft 11. The rotating shaft 7 and the rotating shaft 8 are installed inside the connecting pipe 2. A docking seat 17 is installed at one end of both the rotating shaft 7 and the rotating shaft 8. A grinding wheel 5 is installed at one end of the rotating shaft 7, and a cutting wheel 6 is installed at one end of the rotating shaft 8.
[0025] The first docking seat 16 has a docking groove 29 arranged in a ring array at one end, and the second docking seat 17 has a docking pin 30 arranged in a ring array at one end. The outer wall of the docking pin 30 and the inner wall of the docking groove 29 are both provided with corresponding arc surfaces.
[0026] Each connecting pipe 2 is equipped with a bearing bracket 12, and the mounting shaft 11 is rotatably mounted inside the bearing bracket 12;
[0027] A mounting sleeve 18 is sleeved on the outer side of rotating shaft 7 and rotating shaft 8, and a stroke rod 4 is provided on the upper end of the mounting sleeve 18;
[0028] The upper end of the connecting pipe 2 is provided with a stroke groove 3, and the stroke rod 4 is slidably installed inside the stroke groove 3;
[0029] A support block 21 is provided on the outer wall of the connecting pipe 2. A sliding sleeve 22 is embedded inside the support block 21. A positioning rod 23 is slidably inserted inside the sliding sleeve 22. A symmetrically distributed positioning hole 19 is opened inside the upper end of the stroke rod 4 and is slidably inserted with the positioning rod 23.
[0030] A limiting ring 24 is sleeved on the outer wall of the positioning rod 23. A spring 25 is sleeved on the outside of the positioning rod 23 between the limiting ring 24 and the support block 21. A pull ring 20 is provided at the upper end of the positioning rod 23.
[0031] Both the outer walls of the rotating shaft 7 and the rotating shaft 8 are fitted with mounting rings 26 that are rotatably installed inside the mounting sleeve 18. The outer walls of the mounting rings 26 are rotatably installed with balls 27 arranged in a ring array. The outer walls of both ends of the mounting rings 26 are rotatably installed with balls 28 arranged in a ring array.
[0032] The lower end of the mounting sleeve 18 is set on the slider 10, and the inner wall of the lower end of the connecting tube 2 is provided with a guide rail 9 that is slidably installed with the slider 10;
[0033] Based on the implementation steps of Embodiment 1: In use, the operator first starts the motor 13, grips the outer wall of the connecting cylinder, and the bevel gear 14 at the output end of the motor 13 drives the bevel gear 15 at one end of the mounting shaft 11 to rotate, thereby driving the mounting shaft 11 to rotate. One end of the mounting shaft 11 is provided with a docking seat 16, while one end of the rotating shaft 7 and the rotating shaft 8 inside the connecting pipe 2 is respectively provided with a docking seat 17. By docking the docking groove 29 of the docking seat 16 with the docking pin 30 of the docking seat 17, the arc surface design of the outer walls of both is used to guide the docking process and achieve precise torque transmission. After docking, the rotating shaft 7 and the rotating shaft 8 can drive the grinding wheel 5 and the cutting wheel 6 to rotate respectively. According to the processing requirements, the operator can adjust the position of the grinding wheel 5 or the cutting wheel 6 by moving the mounting sleeve 18 to realize the use of different equipment.
[0034] The stroke rod 4 is slidably installed in the stroke groove 3 at the upper end of the connecting pipe 2. When it is necessary to switch the grinding or cutting function, the operator grasps the stroke rod 4 to drive the mounting sleeve 18 to move outside the rotating shaft 7 and rotating shaft 8, so that the corresponding rotating shaft is connected with the mounting shaft 11. In order to ensure that the mounting sleeve 18 can be stably positioned after movement, a sliding sleeve 22 is embedded in the support block 21 on the outer wall of the connecting pipe 2. The positioning rod 23 slidably inserted in the sliding sleeve 22 can be inserted into the positioning hole 19 at the upper end of the stroke rod 4 under the action of the spring 25, so as to achieve reliable fixation of the mounting sleeve 18. In addition, a mounting ring 26 is also sleeved on the outer side of the rotating shaft 7 and rotating shaft 8. The outer wall and both ends of the mounting ring 26 are rotatably installed with balls, which effectively reduces the frictional resistance between the rotating shaft and the mounting sleeve 18, making the mounting sleeve 18 move more smoothly and also extending the service life of the equipment.
[0035] Compared to traditional independent grinding and cutting machines, this utility model achieves rapid switching between grinding and cutting functions through a single motor 13 drive and transmission structure. This avoids energy waste caused by two sets of equipment running idle at the same time and increases the load on motor 13. At the same time, since the grinding wheel 5 and the cutting wheel 6 can maintain a safe distance from the workpiece in standby mode, it effectively prevents safety hazards caused by accidental contact. This integrated machine has a compact structure and is easy to operate, which not only reduces the cost of use but also improves the practicality and safety of the equipment.
