Description

Technical Field

[0001] This utility model relates to the field of engine cylinder block processing technology, specifically a multi-station engine cylinder block end face grinding device. Background Technology

[0002] An engine block is a structure that contains the cylinders and other components of an internal combustion engine. In early automobile engines, the engine block consisted only of the cylinder block and a separate crankcase. Modern engine blocks typically integrate the crankcase and cylinder block into a single assembly. During engine block production, the surface needs to be polished to remove burrs.

[0003] Most grinding discs are fixed to the drive shaft of the grinding machine by fasteners. When disassembling and assembling the grinding disc, the operator needs to use tools. The replacement process is time-consuming and laborious, making it difficult to achieve convenient replacement of the grinding disc.

[0004] As disclosed in CN220260421U, an engine cylinder block end face grinding device allows the operator to rotate a rotating wheel, causing two insert blocks to move relative to each other and disengage from the slots. This allows the operator to remove the grinding disc from the mounting shaft. After placing a new grinding disc on the mounting shaft, the operator rotates the rotating wheel in the opposite direction, causing the two insert blocks to move away from each other and re-insert into the slots, thus positioning the grinding disc and completing its installation. This enables quick replacement of the grinding disc, allowing operators to quickly disassemble and assemble it by hand. The replacement process is time-saving and labor-saving, achieving convenient grinding disc replacement.

[0005] However, during the use of this device, after the engine block is ground, the ground engine block needs to be removed and then the engine block to be ground is placed on the worktable. The process of removing and placing the engine block wastes a certain amount of time, thereby reducing the processing efficiency of the engine block.

[0006] Therefore, we urgently need to provide a multi-station engine cylinder end face grinding device. Utility Model Content

[0007] The purpose of this invention is to provide a multi-station engine cylinder block end face grinding device to solve the problem mentioned in the background art of wasting time and reducing the processing efficiency of engine cylinder blocks during the engine cylinder block loading and unloading process.

[0008] To achieve the above objectives, the present invention provides the following technical solution: a multi-station engine cylinder end face grinding device, comprising a worktable and a support, wherein the support is fixedly installed on the top of the worktable, and a grinding device is provided on the top of the worktable, the grinding device comprising a switching mechanism, a fixing mechanism and a grinding mechanism.

[0010] The switching mechanism includes a rotating shaft, a processing table, an annular block, a support rod, rollers, a first motor, an output shaft, and gears. The rotating shaft is rotatably connected to the top of the worktable, the processing table is fixedly installed on the top of the rotating shaft, the annular block is fixedly installed on the bottom of the processing table, the support rod is fixedly installed around the bottom of the annular block, the rollers are rotatably connected to the bottom of the support rod, the first motor is fixedly installed inside the left side of the worktable, the output shaft is fixedly installed on the top of the first motor, and the gear is fixedly installed on the outer side of the upper end of the output shaft.

[0011] Preferably, the outer surface of the annular block is provided with toothed grooves, and the gear meshes with the toothed grooves of the annular block. By starting the motor, the output shaft and the gear rotate and mesh with the toothed grooves of the annular block, thereby causing the annular block to drive the processing table to rotate around the rotating shaft, realizing the switching of the four processing stations on the top of the processing table.

[0012] Preferably, the upper surface of the worktable is provided with an annular groove, and the roller is rotatably connected to the inner wall of the annular groove. The roller and the support rod cooperate to support the annular block and the worktable, thereby improving the stability of the worktable.

[0013] Preferably, the fixing mechanism includes a fixed clamping plate, a telescopic component one, and a movable clamping plate. The fixed clamping plate is fixedly installed on the top of the processing table, the telescopic component one is fixedly installed on the top of the processing table, and the movable clamping plate is fixedly installed at the output end of the telescopic component one.

[0014] Preferably, there are four fixing mechanisms, which are distributed at equal angles on the top of the processing table. A rubber pad is installed on the side of the fixed clamping plate and the movable clamping plate adjacent to each other. The rubber pad prevents the movable clamping plate and the fixed clamping plate from causing scratches on the surface of the cylinder block when they clamp the engine cylinder block.

[0015] Preferably, the grinding mechanism includes a second motor, a threaded rod, a moving block, a second telescopic component, a support plate, a telescopic rod, and a grinding machine.

When the movable block is threadedly connected to the threaded rod, the movement of the movable block is limited by the cooperation between the protrusion and the sliding groove, so that the movable block drives the grinding machine to move back and forth in a straight line, thereby realizing the position adjustment of the grinding machine.

[0017] Preferably, the bottom of the telescopic rod is fixedly connected to the top of the support plate. The telescopic rod reduces the torque generated on the telescopic component two when the grinder rotates, thereby improving the service life of the telescopic component two and improving the grinding stability of the engine cylinder block.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.

[0027] Example 1:

[0028] The existing technology wastes time during the engine block loading and unloading process, reducing the efficiency of engine block processing. Please refer to [link / reference needed]. Figures 1-4 This embodiment provides a multi-station engine cylinder block end face grinding device, which can shorten the time for picking up and placing engine cylinder blocks and the idle time of the grinding machine, and improve the processing efficiency of engine cylinder blocks. The multi-station engine cylinder block end face grinding device includes a worktable 1 and a support 2. The support 2 is fixedly installed on the top of the worktable 1. A grinding device is provided on the top of the worktable 1. The grinding device includes a switching mechanism, a fixing mechanism and a grinding mechanism.

[0029] The switching mechanism is located on the top of the worktable 1, the fixing mechanism is located on the top of the switching mechanism, and the grinding mechanism is located above the worktable 1.

[0030] The switching mechanism includes a rotating shaft 301, a processing table 302, an annular block 303, a support rod 304, a roller 305, a motor 306, an output shaft 307, and a gear 308. The rotating shaft 301 is rotatably connected to the top of the worktable 1, and the lower end of the rotating shaft 301 is mounted to the worktable 1 via a bearing. The processing table 302 is fixedly mounted on the top of the rotating shaft 301, and the annular block 303 is fixedly mounted on the bottom of the processing table 302. The outer surface of the annular block 303 has toothed grooves, and the gear 308 meshes with the toothed grooves of the annular block 303. By starting the motor 306, the output shaft 307 and the gear 308 are driven to rotate and mesh with the toothed grooves of the annular block 303, thereby causing the annular block 303 to rotate. The machining table 302 is rotated around the rotating shaft 301, enabling the switching of the four machining stations on the top of the machining table 302. The support rod 304 is fixedly installed around the bottom of the annular block 303, and the roller 305 is rotatably connected to the bottom of the support rod 304. An annular groove is provided on the upper surface of the worktable 1, and the roller 305 is rolled and connected to the inner wall of the annular groove. The roller 305 and the support rod 304 cooperate to support the annular block 303 and the machining table 302, improving the stability of the machining table 302. The motor 306 is fixedly installed inside the left side of the worktable 1, the output shaft 307 is fixedly installed on the top of the motor 306, and the gear 308 is fixedly installed on the outer side of the upper end of the output shaft 307.

[0031] To prevent the engine block from shaking during grinding, it needs to be clamped and fixed. Therefore, this device is also equipped with a fixing mechanism, which includes a fixed clamping plate 401, a telescopic component 402, and a movable clamping plate 403. The fixed clamping plate 401 is fixedly installed on the top of the processing table 302. There are four fixing mechanisms, which are evenly distributed on the top of the processing table 302. The four fixing mechanisms are four processing stations. Rubber pads are installed on the adjacent side of the fixed clamping plate 401 and the movable clamping plate 403. The rubber pads prevent the movable clamping plate 403 and the fixed clamping plate 401 from scratching the surface of the engine block when clamping the engine block. The telescopic component 402 is a cylinder of model QTB, which is fixedly installed on the top of the processing table 302. The movable clamping plate 403 is fixedly installed at the output end of the telescopic component 402.

[0032] Example 2:

[0033] Based on Example 1, please refer to Figures 1-4 To improve the grinding flexibility of the engine block and achieve position adjustment of the grinder 507, this device also includes a grinding mechanism. The grinding mechanism includes a second motor 501, a threaded rod 502, a moving block 503, a second telescopic component 504, a support plate 505, a telescopic rod 506, and the grinder 507. The second motor 501 is fixedly mounted on the upper back of the bracket 2. The threaded rod 502 is fixedly mounted on the output end of the second motor 501. The moving block 503 is threadedly connected to the outside of the threaded rod 502. A groove is provided on the upper inner surface of the bracket 2. A protrusion is provided on the upper end of the moving block 503, and the protrusion is slidably connected to the inner wall of the groove. When the moving block 503 is threadedly connected to the threaded rod 502, the protrusion, in cooperation with the groove, limits the movement of the moving block 503, allowing it to move... The moving block 503 drives the grinding machine 507 to move linearly back and forth, thereby adjusting the position of the grinding machine 507. The telescopic component 504 is fixedly installed at the bottom of the moving block 503. The telescopic component 504 is of model XTL and its length is adjustable, which facilitates the adjustment of the lifting height of the grinding machine 507. The support plate 505 is fixedly installed at the bottom of the telescopic component 504. The telescopic rod 506 is fixedly installed on the top left and right sides inside the bracket 2. The bottom of the telescopic rod 506 is fixedly connected to the top of the support plate 505. The telescopic rod 506 reduces the torque generated on the telescopic component 504 when the grinding machine 507 rotates, thereby improving the service life of the telescopic component 504 and improving the grinding stability of the engine cylinder block. The grinding machine 507 is fixedly installed at the bottom of the support plate 505.

[0034] In use, the engine block to be ground is placed on top of the machining table 302, and the telescopic component 402 is activated to push the movable clamping plate 403 to clamp the engine block. Then, the motor 306 is started, driving the output shaft 307 and gear 308 to rotate and mesh with the toothed grooves in the annular block 303. This causes the annular block 303 to drive the machining table 302 to rotate around the rotating shaft 301. When the engine block moves directly below the grinder 507, the telescopic component 504 is activated to push the grinder 507 downwards, thus grinding the engine block. The engine cylinder block is ground. After grinding, the motor 306 is started again to rotate the processing table 302 until the next engine cylinder block is moved directly under the grinding machine 507. Then the grinding machine 507 grinds the engine cylinder block. At the same time, the previously ground engine cylinder block can be removed, and the engine cylinder block to be ground is fixed on the top of the processing table 302 again. This process is repeated to shorten the time for picking up and putting down the engine cylinder block, reduce the idle time of the grinding machine 507, and thus improve the processing efficiency of the engine cylinder block.
