[0001] This application relates to the technical field of grinding equipment, and in particular to a grinding apparatus for a streamlined, low-noise crankshaft. Background Technology

[0002] As a core component of the engine, the crankshaft's machining accuracy directly affects the engine's performance and lifespan. Currently, crankshaft grinding technology has evolved from traditional manual grinding to CNC grinding, significantly improving machining accuracy and efficiency.

[0003] The existing publication number CN212762594U, entitled "A Grinding Equipment Based on Crankshaft Machining," includes a base, a U-shaped bracket fixedly mounted on the top of the base, a groove formed on the inner wall of the top of the U-shaped bracket, and a lead screw rotatably mounted on both inner walls of the groove. One end of the lead screw passes through one side of the bracket. A first motor is fixedly mounted on the top of the U-shaped bracket, a first pulley is fixedly mounted on the end of the lead screw near the first motor, a second pulley is fixedly mounted on the output shaft of the first motor, a lead screw sleeve is threaded onto the lead screw, and a second motor is fixedly mounted on the bottom ends of two telescopic rods away from the lead screw sleeve. This utility model is easy to operate, provides a more secure fixation of the crankshaft during crankshaft machining, and allows for timely cooling of the grinding blade for efficient grinding, greatly reducing risks and accelerating production.

[0004] Regarding the aforementioned technologies, the inventors discovered that the vibrations generated during the grinding process of the grinding blades and the operation of the mechanical equipment cause vibration noise in the grinding device, leading to an increasingly prominent problem of processing noise in the grinding equipment, and making it impossible to reduce the noise environment of the grinding equipment. Utility Model Content

[0005] In order to overcome the problem that vibrations generated during the processing of grinding blades and operation of mechanical equipment in existing grinding devices cause vibration noise in the grinding device, resulting in increasingly prominent processing noise problems and the inability to reduce the noise environment of grinding equipment, this application provides a grinding device for a streamlined low-noise crankshaft.

[0006] The grinding device for a streamlined, low-noise crankshaft provided in this application adopts the following technical solution:

[0007] A grinding device for a streamlined, low-noise crankshaft includes a frame, a processing table, an adjustment assembly, a locking component, and a grinding motor. The processing table is horizontally fixed on the top surface of the frame, and the adjustment assembly is provided on the top surface of the processing table. The adjustment assembly includes an X-axis adjustment component, a Y-axis adjustment component, a Z-axis adjustment component, and a moving table. The X-axis adjustment component is slidably assembled on the top surface of the processing table along the X-axis direction, and a Y-axis adjustment component is slidably assembled on the X-axis adjustment component along the Y-axis direction. A Z-axis adjustment component is slidably assembled on the Y-axis adjustment component along the Z-axis direction, and a moving table is mounted on the Z-axis adjustment component. The grinding motor is mounted on the moving table via the locking component.

[0008] By adopting the above technical solution, the grinding motor is locked to the front of the moving table by a locking component during use. Then, the crankshaft to be ground is horizontally clamped and fixed on the processing table. The processing position of the moving table is adjusted by the X-axis, Y-axis and Z-axis adjustment components of the adjustment assembly. This is suitable for the position requirements of crankshaft grinding. The locking component helps to stop the vibration generated by the grinding motor and the noise of the grinding tool, thereby reducing the noise environment of the grinding equipment.

[0009] Optionally, the locking components include a rubber back seat and a rubber front seat, which are respectively located on the front and rear sides of the grinding motor. A clamping frame is vertically installed on the outer side of the rubber front seat, and the top of the clamping frame is threaded onto the moving table by locking bolts.

[0010] By adopting the above technical solution, the rubber back seat and rubber front seat in the locking component are respectively set on the front and rear sides of the grinding motor to support and install the grinding motor on the front end face of the moving table. The rubber front seat is pressed against the grinding motor on the front side of the moving table by the clamping frame. The vibration generated by the grinding motor is absorbed by the deformation of the rubber back seat and rubber front seat, avoiding the noise generated by the vibration of the rigidly connected grinding motor and improving the noise reduction effect of the grinding equipment.

[0011] Optionally, multiple anchor rods are symmetrically and horizontally fixed on the front end face of the moving stage, and the multiple anchor rods are inserted and connected to the rubber back seat and the rubber front seat on the front and rear sides of the grinding motor.

[0012] By adopting the above technical solution, multiple anchor rods fixed to the front end face of the moving stage are used to anchor the rubber back seat and rubber front seat of the insert support, ensuring the stability of the grinding motor supported by the rubber back seat and rubber front seat on the front end face of the moving stage in the later stage.

[0013] Optionally, a damping rod is horizontally fixed to the front side of the inner side of the clamping frame, and a pressure plate is vertically fixed to the other end of the damping rod, with the pressure plate pressing against the rubber front seat.

[0014] By adopting the above technical solution, the damping rod pushes the pressure plate to press against the rubber front seat, clamping and installing the grinding motor between the rubber back seat and the rubber front seat, thereby improving the vibration reduction performance of the grinding motor during processing.

[0015] Optionally, a spring is horizontally sleeved on the outside of the damping rod, and the two ends of the spring are fixed to the clamping frame and the pressure plate, respectively.

[0016] By adopting the above technical solution, the vibration generated when the grinding motor is working causes the spring to deform and the damping rod to extend, absorbing the vibration. The potential energy of the spring deformation is offset by the damping force of the damping rod, which reduces the mechanical vibration when the grinding motor is working and improves the stability of the grinding motor during operation.

[0017] Optionally, the bottom of the clamping frame is provided with a grinding wheel cover, which includes a housing fixed to the bottom surface of the clamping frame and positioned behind the cutting tool of the grinding motor.

[0018] By adopting the above technical solution, the grinding wheel cover is installed behind the tool of the grinding motor, which further blocks the path of the noise generated by the tool processing of the grinding motor to the outside, thereby improving the noise level of the grinding equipment.

[0019] Optionally, the interior of the cover is provided with a hollow cavity, and the hollow cavity is filled with sound insulation cotton.

[0020] By adopting the above technical solution, the hollow cavity inside the cover is filled with sound-insulating cotton, which utilizes an internal porous design to counteract the noise generated by the grinding motor's cutting tool.

[0021] Optionally, felt sheets are fixed to the inner wall of the casing.

[0022] By adopting the above technical solution, the felt sheet fixed inside the casing further cancels out noise transmission by utilizing the porous structure of the felt sheet.

[0023] In summary, this application includes at least one of the following beneficial technical effects: by using the rubber back seat and rubber front seat in the locking component to be respectively set on the front and rear sides of the grinding motor, the grinding motor is supported and installed on the front end face of the moving table, and the rubber front seat is pressed against the grinding motor on the front side of the moving table by the clamping frame. The vibration generated by the grinding motor during processing is absorbed by the deformation of the rubber back seat and rubber front seat, avoiding the noise generated by the vibration of the rigidly connected grinding motor, and improving the noise reduction effect of the grinding equipment.

[0030] The present application will be further described in detail below with reference to the accompanying drawings.

[0031] This application discloses a grinding apparatus for a streamlined, low-noise crankshaft. (Refer to...) Figure 1 , Figure 2 , Figure 3 and Figure 4 A grinding device for a streamlined, low-noise crankshaft includes a frame 1, a processing table 2, an adjustment assembly 3, a locking element 4, and a grinding motor 5. The processing table 2 is horizontally fixed on the top surface of the frame 1, and the adjustment assembly 3 is provided on the top surface of the processing table 2. The adjustment assembly 3 includes an X-axis adjustment component 31, a Y-axis adjustment component 32, a Z-axis adjustment component 33, and a moving table 34. The X-axis adjustment component 31 is slidably assembled on the top surface of the processing table 2 along the X-axis direction, and the Y-axis adjustment component 32 is slidably assembled on the X-axis adjustment component 31 along the Y-axis direction. The Z-axis adjustment component 33 is slidably assembled on the Y-axis adjustment component 32 along the Z-axis direction, and the moving table 34 is mounted on the Z-axis adjustment component 33. The grinding motor 5 is mounted on the moving table 34 through the locking element 4.

[0032] By adopting the above technical solution, the grinding motor 5 is locked and installed on the front side of the moving table 34 by the locking member 4. Then, the crankshaft to be ground is horizontally clamped and fixed on the processing table 2. The processing position of the moving table 34 is adjusted by the X-axis adjustment member 31, Y-axis adjustment member 32 and Z-axis adjustment member 33 of the adjustment component 3. This is suitable for the position requirements of crankshaft grinding. The locking member 4 is set to facilitate the subsequent vibration reduction of the grinding motor 5 and the noise of the grinding tool of the grinding motor 5, thereby reducing the noise environment of the grinding equipment.

[0033] Reference Figure 3 and Figure 4 The locking component 4 includes a rubber back seat 41 and a rubber front seat 42, which are respectively located on the front and rear sides of the grinding motor 5. A clamping frame 43 is vertically installed on the outer side of the rubber front seat 42, and the top of the clamping frame 43 is threaded onto the moving table 34 by locking bolts 431. In use, the rubber back seat 41 and rubber front seat 42 in the locking component 2 are respectively located on the front and rear sides of the grinding motor 5 to support and install the grinding motor 5 on the front end face of the moving table 34. The clamping frame 43 presses the rubber front seat 42 against the grinding motor 5 on the front side of the moving table. The vibration generated by the grinding motor 5 during processing is absorbed by the deformation of the rubber back seat 41 and rubber front seat 42, avoiding noise generated by the vibration of the rigidly connected grinding motor 5, and improving the noise reduction effect of the grinding equipment. Multiple anchor rods 35 are symmetrically and horizontally fixed on the front end face of the moving table 34, and the multiple anchor rods 35 are inserted and connected to the rubber back seat 41 and rubber front seat 42 on the front and rear sides of the grinding motor 5. Multiple anchor rods 35 fixed to the front end face of the moving table 34 are used to anchor the rubber back support 41 and the rubber front support 42, ensuring the stability of the grinding motor 5 supported by the rubber back support 41 and the rubber front support 42 on the front end face of the moving table 34 in the later stage.

[0034] Reference Figure 3 and Figure 4 A damping rod 44 is horizontally fixed to the front side of the clamping frame 43, and a pressure plate 46 is vertically fixed to the other end of the damping rod 44, with the pressure plate 46 pressing against the rubber front seat 42. The damping rod 44 pushes the pressure plate 46 to press against the rubber front seat 42, clamping and installing the grinding motor 5 between the rubber back seat 41 and the rubber front seat 42, thus improving the vibration damping of the grinding motor 5. A spring 45 is horizontally sleeved on the outside of the damping rod 44, and the two ends of the spring 45 are fixed to the clamping frame 43 and the pressure plate 46, respectively. The vibration generated when the grinding motor 5 is working causes the spring 45 to deform and the damping rod 44 to extend, absorbing the vibration. The deformation potential energy of the spring 45 is offset by the restoring damping force of the damping rod 44, reducing the mechanical vibration of the grinding motor 5 during operation and improving the stability of the grinding motor 5 during operation.

[0035] Reference Figure 4 and Figure 5The bottom of the clamping frame 43 is covered with a grinding wheel cover 47, which includes a housing 471. The housing 471 is fixed to the bottom surface of the clamping frame 43 and is positioned behind the cutting tool of the grinding motor 5. The grinding wheel cover 47, positioned behind the cutting tool of the grinding motor 5, further blocks the path of noise generated by the grinding motor 5 during tool processing, improving the noise reduction of the grinding equipment. The housing 471 has a hollow cavity 472 filled with sound-absorbing cotton 474. The sound-absorbing cotton 474, with its porous structure, effectively cancels out the noise generated by the grinding motor 5 during tool processing. Felt sheets 473 are fixed to the inner wall of the housing 471. The porous structure of the felt sheets 473 further reduces noise transmission.

[0036] The implementation principle of the streamlined low-noise crankshaft grinding device in this application embodiment is as follows: During use, the grinding motor 5 is locked and installed on the front side of the moving table 34 by the locking member 4. Then, the crankshaft to be ground is horizontally clamped and fixed on the processing table 2. The processing position of the moving table 34 is adjusted by the X-axis adjustment member 31, Y-axis adjustment member 32 and Z-axis adjustment member 33 of the adjustment assembly 3 to meet the position requirements of crankshaft grinding. The rubber back seat 41 and rubber front seat 42 in the locking member 2 are respectively set on the front and rear sides of the grinding motor 5. Multiple anchor rods 35 fixed on the front end face of the moving table 34 are used to anchor the insert support of the rubber back seat 41 and rubber front seat 42, support and install the grinding motor 5 on the front end face of the moving table 34, and press it with the clamping frame 43. The rubber front seat 42 presses against the grinding motor 5 on the front side of the moving table. The vibration generated by the grinding motor 5 during processing is absorbed by the deformation of the rubber back seat 41 and the rubber front seat 42. The vibration generated by the grinding motor 5 during operation causes the spring 45 to deform and the damping rod 44 to extend, absorbing the vibration. The deformation potential energy of the spring 45 is offset by the restoring damping force of the damping rod 44, reducing the mechanical vibration of the grinding motor 5 during operation and improving the stability of the grinding motor 5 during operation. The grinding wheel cover 47 is installed behind the tool of the grinding motor 5, further blocking the path of noise generated by the tool processing of the grinding motor 5 to the outside. The sound insulation cotton 474 filled in the hollow cavity 472 inside the cover 471 and the felt sheet 473 fixed inside the cover 471 further offset the noise transmission by utilizing the porous structure of the felt sheet 473.

[0037] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
