Description

Technical Field

[0001] The invention belongs to the technical field of camshaft grinding, and in particular relates to a camshaft grinding structure. Background Art

[0002] The camshaft is one of the most important components in the internal combustion engine, and is mainly responsible for controlling the opening and closing timing of the engine valves. It is connected to the crankshaft of the engine, and uses the cam profile (cam profile) installed on it to push the rocker arm of the valve or directly control the lifting and lowering of the valve. The design and performance of the camshaft directly affect the intake and exhaust process of the engine, and then affect the engine's power, fuel efficiency and emission level. With the advancement of technology, the camshaft in modern engines often adopts a variable valve timing (VVT) system, which can automatically adjust the phase of the camshaft according to the engine speed and load conditions to optimize the engine's performance and efficiency. Therefore, the camshaft is not only a core component in the engine's mechanical structure, but also one of the key factors affecting the engine's fuel economy, power output and emission control.

[0003] The camshaft is at the very end of the engine lubrication system, and the remaining burrs may cause malfunctions in the lubrication system. The existing camshaft grinding structure is generally manually positioned and ground by operators, and the grinding has high repetition and low precision. At the same time, the camshaft has an irregular shape and many corners, resulting in insufficient treatment of the remaining burrs on the camshaft, which is easy to cause damage when the internal combustion engine is working. In addition, when manual grinding is used, multiple camshafts cannot be ground synchronously at the same time, and the degree and depth of grinding cannot be controlled, thereby reducing the grinding effect of the grinding structure on the camshaft. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a camshaft grinding structure.

[0005] The technical solution adopted to solve the above technical problems is: a camshaft grinding structure, comprising a main body, a base is fixedly connected to the bottom of the main body, and an internal groove is opened inside one side of the main body; A transmission mechanism is installed on the inner wall of the inner groove, an adjustment mechanism is installed on the outer wall of the transmission mechanism, a grinding mechanism is installed inside the main body, and a plurality of fixing mechanisms are installed on one end of the grinding mechanism.

[0006] Furthermore, the transmission mechanism includes a first motor fixedly connected to the inner wall of one side of the main body, the output end of the first motor is fixedly connected to the first driving shaft, the outer wall of the first driving shaft is fixedly connected to the first gear, the inner wall of the internal groove is rotatably connected to two second gears, the outer walls of the two second gears are meshed with third gears, one side of the third gears is fixedly connected to a threaded rod, and one side of the other third gear is fixedly connected to a limiting shaft, and the first gear is respectively meshed with the two second gears.

[0007] According to the above technical solution, when the camshaft is placed in the grinding structure, the transmission mechanism can help the camshaft to rotate and move with other components, so that the grinding structure can achieve comprehensive grinding on the camshaft, and can cooperate with other components to realize the rotation of the camshaft itself. By rotating the camshaft and the grinding component at the same time, the working surface of the grinding component can cover more parts of the camshaft, thereby improving the processing efficiency. The rotating camshaft helps to avoid the grinding component staying in certain areas for too long, avoid unnecessary excessive wear and accelerate the processing progress. In addition, the transmission mechanism cooperates with other components and can be adjusted according to the specifications of the camshaft, thereby effectively improving the applicability of the grinding structure. Specifically, the camshaft is placed in the grinding structure, and then the first motor on the inner wall of one side of the main body is started to drive the two first gears meshing on the outer wall of the first drive shaft to start rotating, and then the third gear on one side of the two first gears starts to rotate, and then the threaded rod and the limit shaft are respectively driven to rotate. At the same time, the diameter difference between the first gear and the third gear is used to effectively distinguish the rotation speed of the camshaft itself from the grinding speed, so as to ensure the grinding effect, thereby driving the grinding component to grind and cooperate to adjust, and the overall functionality is maximized.

[0008] Furthermore, the adjustment mechanism includes two hydraulic cylinders rotatably connected to the outer wall of the first drive shaft, arc grooves are opened on opposite sides inside the main body, one side of the two second gears and the third gear is respectively rotatably connected with connecting rods, and the two piston ends of the hydraulic cylinders are respectively rotatably connected to the shaft on the other side of the corresponding third gear.

[0009] Through the above technical solution, after the camshaft is placed, the adjustment mechanism is used in conjunction with the transmission mechanism. First, when the transmission mechanism rotates, as other components grind the camshaft, the adjustment mechanism can be telescopically adjusted according to the change to ensure that the grinding structure can meet the size of the camshaft specifications. At the same time, the camshaft can be adjusted on both sides when it changes in height to ensure that the grinding components can move smoothly. Specifically, when the camshaft is being ground, as the diameter of the outer wall of the camshaft changes, starting the two hydraulic cylinders will drive the piston end to contract, and then the piston end will drive the two third gears to contract in the arc groove, and then the two third gears will rotate along the corresponding second gears to ensure the fit between the grinding component and the camshaft during grinding.

[0010] Furthermore, the grinding mechanism includes a fixed strip fixedly connected to the opposite sides of the main body, one of the fixed strips is rotatably connected to a plurality of rotating shafts, and the outer wall synchronous wheels of the plurality of rotating shafts are rotatably connected to synchronous toothed belts, and another fixed strip is fixedly connected to a round block on one side, a plurality of the round blocks are provided with circular grooves, and the outer walls of the plurality of round blocks are rotatably connected to grinding belts, the inner wall of the grinding belt is rotatably connected to two belt rings, the inner wall of the synchronous toothed belt is rotatably connected to the first driving shaft, one of the inner wall of the belt ring is threadedly connected to the threaded rod, and the inner wall of the other belt ring is slidably connected to the limit shaft.

[0011] Through the above technical solution, after the camshaft is placed in the grinding structure, the grinding mechanism, the transmission mechanism and the adjustment mechanism can be used to fully grind the camshaft. When used in conjunction with the transmission mechanism, the grinding mechanism can move repeatedly on the camshaft, and the grinding mechanism reciprocates on the camshaft through the transmission mechanism, and can ensure the normal rotation of the grinding mechanism. This reciprocating motion helps to ensure that the grinding belt evenly distributes friction on the entire camshaft surface, avoiding local over-grinding or insufficient grinding, and can cooperate with the adjustment mechanism to help the grinding mechanism adapt and adjust according to the specifications and changes of the camshaft during grinding, ensuring normal grinding. Multiple camshafts are cross-connected through the grinding mechanism. Through cross-synchronous grinding and precise adjustment of the movement trajectory of the grinding belt, it can be ensured that multiple camshafts are polished at the same time, and the surface of each camshaft can be evenly polished, avoiding quality differences caused by uneven treatment of different workpieces. In addition, the cross method can make the utilization rate of the grinding mechanism higher. , longer service life. Specifically, one end of multiple camshafts is placed in the circular grooves inside multiple round blocks in the air to ensure centering and the grinding belt can move normally to the camshaft. As the threaded rod and the limit shaft rotate, the two belt rings will be driven to rotate respectively, one of which will move on the threaded rod, and the other will drive the grinding belt to rotate according to the rotation of the limit shaft. As one of the belt rings moves, the grinding belt will be offset, and then the grinding belt will be driven to rotate on the camshaft. At this time, the piston ends of the two hydraulic cylinders can be contracted to drive the corresponding threaded rods and the limit shafts to be adjusted to ensure the fit of the grinding belt on the camshaft. At the same time, when the grinding belt is at the high and low exchange position on the camshaft, the corresponding hydraulic cylinder can be selected according to the situation of the camshaft to adjust along the arc groove. The hydraulic cylinder at the rear end can adjust the upper and lower camshafts in the circular groove on the fixed strip, and the front end can adjust the two in the middle to ensure that the grinding belt can move normally. At the same time, the grinding of the grinding belt on the camshaft can be accurate to the corner, so that the grinding can be more perfect.

[0012] Furthermore, the fixing mechanism includes a fixing frame fixedly connected to the other end of the rotating shaft, a second motor is fixedly connected inside the fixing frame, a second driving shaft is fixedly connected to the output end of the second motor, a first circular plate is fixedly connected to the other end of the second driving shaft, a plurality of annular grooves are provided inside the first circular plate, a second circular plate is fixedly connected to one side of the fixing frame, a plurality of limiting grooves are provided inside the second circular plate, cylinders are slidably connected inside the plurality of limiting grooves, extrusion blocks are fixedly connected at one end of the plurality of cylinders, the other ends of the plurality of cylinders are slidably connected to the corresponding annular grooves, and the first circular plate is located between the fixing frame and the second circular plate.

[0013] Through the above technical scheme, the camshaft is first placed in the grinding structure, and the camshaft can be fixed by the fixing mechanism at this time. At the same time, the camshaft itself can be rotated under the cooperation of the movement of the grinding mechanism to ensure that the camshaft does not stay in the contact position with the grinding belt, so that the grinding belt moves more smoothly. Specifically, multiple camshafts are placed in the grinding structure, and multiple fixed frames are started. The second motor fixedly connected inside the fixed frames drives the corresponding second drive shaft to rotate, and then the corresponding annular groove on the first circular plate is driven to rotate. Then, the other ends of the multiple cylinders will move in the limiting groove on the corresponding second circular plate with the rotation of the annular groove, and then the multiple camshafts are clamped respectively. The other ends of the multiple camshafts will drive the synchronous toothed belt on the outer wall to rotate with the rotation of the first drive shaft, and then the multiple fixed frames connected to the rotating shaft are rotated, so that the multiple camshafts can rotate, thereby realizing grinding and adjustment.

[0014] The beneficial effects of the present invention are as follows: (1) The present invention designs a transmission mechanism, an adjustment mechanism, a grinding mechanism and a fixing mechanism. When the camshaft is being ground, the camshaft itself and the grinding belt can be rotated, thereby avoiding excessive wear of the grinding belt and the camshaft in certain areas and improving the uniformity of the grinding process. In particular, when the camshaft surface has complex curves and transition areas, such a speed difference can effectively prevent excessive wear or scratches. At the same time, the grinding belt can move on the camshaft, and the grinding belt can be adjusted according to the tightness, so that camshafts of different diameters can be ground. The overall grinding structure has higher applicability. (2) The present invention designs a transmission mechanism, a grinding mechanism and a fixing mechanism. When the camshaft is being ground, one side of the camshaft can be clamped and rotated by itself. When the camshaft is clamped and rotated in the clamping block, the friction between the grinding belt and the shaft surface is relatively uniform, reducing the situation of excessive friction or overheating on one side and reducing the risk of thermal deformation, which is very important for maintaining the geometric accuracy and surface quality of the camshaft. The transmission mechanism not only drives the grinding belt to rotate, but also drives the grinding belt to move repeatedly on the camshaft. At the same time, the grinding belt crosses on multiple camshafts. The grinding belt reciprocates on the camshaft through the screw. This reciprocating motion helps to ensure that the grinding belt evenly distributes friction on the entire camshaft surface, avoiding local over-grinding or under-grinding, and improving the utilization efficiency of the grinding belt. (3) The present invention uses an adjustment mechanism to adjust the grinding belt when grinding camshafts of different diameters to ensure the grinding fit. At the same time, when the grinding belt moves alternately at different heights of the camshaft, the adjustment mechanism can adjust in different directions with different camshafts, which can effectively improve the grinding efficiency, accuracy and consistency, and ensure the stability and surface quality of the processing process. This structural design is not only highly adaptable and can cope with camshafts of different specifications, but also can improve the degree of automation of production, reduce manual intervention, reduce wear and damage, and thus improve the overall processing quality and efficiency.

The transmission mechanism 4 includes a first motor 401 fixedly connected to the inner wall of one side of the main body 1, a first driving shaft 402 is fixedly connected to the output end of the first motor 401, and a first gear 403 is fixedly connected to the outer wall of the first driving shaft 402. Two second gears 404 are rotatably connected to the inner wall of the internal groove 3, and the outer walls of the two second gears 404 are meshed with third gears 405, one side of one of the third gears 405 is fixedly connected to a threaded rod 406, and one side of the other third gear 405 is fixedly connected to a limited position shaft 407, and the first gear 403 is respectively meshed with the two second gears 404. When in use, after the camshaft is placed in the grinding structure, the transmission mechanism 4 can be used to help the camshaft rotate, and cooperate with other components to move together, so that the grinding structure can achieve comprehensive grinding on the camshaft, and can cooperate with other components to achieve automatic grinding of the camshaft By rotating the camshaft and the grinding component at the same time, the working surface of the grinding component can cover more parts of the camshaft, thereby improving the processing efficiency. The rotating camshaft helps to avoid the grinding component from staying in certain areas for too long, avoiding unnecessary excessive wear and accelerating the processing progress. In addition, the transmission mechanism 4 cooperates with other components and can be adjusted according to the specifications of the camshaft, thereby effectively improving the applicability of the grinding structure. Specifically, the camshaft is placed in the grinding structure, and then the first motor 401 on the inner wall of one side of the main body 1 is started to drive the two first gears 403 engaged with the outer wall of the first drive shaft 402 to start rotating, and then the third gear 405 on one side of the two first gears 403 starts to rotate, and then drives the threaded rod 406 and the limit shaft 407 to rotate respectively. At the same time, the diameter difference between the first gear 403 and the third gear 405 is used to effectively distinguish the rotation speed of the camshaft itself from the grinding speed, thereby ensuring the grinding effect, thereby driving the grinding component to grind and cooperate to adjust, and the overall functionality is maximized.

[0019] like Figure 4-Figure 6As shown, an adjusting mechanism 5 is installed on the outer wall of the transmission mechanism 4, and the adjusting mechanism 5 includes two hydraulic cylinders 501 rotatably connected to the outer wall of the first driving shaft 402. The opposite sides of the main body 1 are provided with arc grooves 502. The two second gears 404 and the third gear 405 are rotatably connected to the connecting rods 503 on one side, and the piston ends of the two hydraulic cylinders 501 are respectively rotatably connected to the shafts on the other side of the corresponding third gears 405. When the camshaft is placed, the adjusting mechanism 5 is used in conjunction with the transmission mechanism 4. First, when the transmission mechanism 4 rotates, as other components grind the camshaft, the adjusting mechanism 5 can be telescopically adjusted according to the change, so as to ensure that the grinding structure can meet the size of the camshaft specifications. At the same time, the camshaft can be adjusted on both sides when it changes in height, so as to ensure that the grinding component can move smoothly. Specifically, when the camshaft is being ground, as the diameter of the outer wall of the camshaft changes, starting the two hydraulic cylinders 501 will drive the piston end to contract, and then the piston end will drive the two third gears 405 to contract in the arc groove 502, and then the two third gears 405 will rotate along the corresponding second gear 404, so as to ensure the fit between the grinding component and the camshaft during grinding.

[0020] like Figure 6-Figure 7As shown, a grinding mechanism 6 is installed inside the main body 1, and the grinding mechanism 6 includes a fixed strip 601 fixedly connected to the opposite side of the main body 1, wherein a plurality of rotating shafts 602 are rotatably connected inside one of the fixed strips 601, and the synchronous wheels on the outer walls of the plurality of rotating shafts 602 are rotatably connected to a synchronous toothed belt 603, and a round block 604 is fixedly connected to one side of the other fixed strip 601, and a circular groove 605 is provided inside the plurality of round blocks 604, and a grinding belt 606 is rotatably connected to the outer walls of the plurality of round blocks 604, and the inner wall of the grinding belt 606 is rotatably connected to two belt rings 607, and the inner wall of the synchronous toothed belt 603 is rotatably connected to the first driving shaft 402, and the inner wall of one belt ring 607 is threadedly connected to the threaded rod 406, and the inner wall of the other belt ring 607 is threadedly connected to the limit shaft 407. Sliding connection, after the camshaft is placed in the grinding structure, the grinding mechanism 6, the transmission mechanism 4 and the adjusting mechanism 5 can be used to fully grind the camshaft. When used in conjunction with the transmission mechanism 4, the grinding mechanism 6 can move repeatedly on the camshaft, and the grinding mechanism 6 reciprocates on the camshaft through the transmission mechanism 4, and can ensure the normal rotation of the grinding mechanism 6. This reciprocating motion helps to ensure that the grinding belt 606 evenly distributes friction on the entire camshaft surface, avoiding local over-grinding or insufficient grinding, and can cooperate with the adjusting mechanism 5 to help the grinding mechanism 6 adapt to the specifications and changes of the camshaft during grinding, thereby ensuring the normal progress of grinding. The structure 6 cross-connects multiple camshafts. Through cross-synchronous grinding and precise adjustment of the movement trajectory of the grinding belt 606, it can be ensured that multiple camshafts are polished at the same time, and the surface of each camshaft can be evenly polished, avoiding quality differences caused by uneven processing of different workpieces.
