Description

Technical Field

[0001] The utility model relates to the technical field of cylinder turning devices, in particular to an engine cylinder turning device. Background Art

[0002] The engine block is the main part of the engine. It connects the cylinders and the crankcase together and provides a support frame for the piston, crankshaft and other parts and accessories. When the engine block is repaired and maintained, it is necessary to lift the engine block to facilitate the operation. When the engine block is lifted, an engine block flip stand is needed.

[0003] The engine block flip stand is a special device used to flip and support the engine block. It allows technicians to easily flip the engine block 360 degrees during maintenance and inspection, so as to perform detailed inspection and maintenance operations on various parts of the block.

[0004] With respect to the existing related technologies, it is believed that the following defects exist: when the engine block is assembled on the turning frame, since the engine block itself has a certain weight and the installation location of the turning frame is at a certain height from the ground, a hook is required to lift the engine block onto the turning frame each time the engine block is installed and disassembled. When there is no lifting tool such as a hook, it will be difficult to install the engine block on the turning frame; therefore, an engine block turning device is proposed to address the above problems. Utility Model Content

[0005] In order to make up for the deficiencies of the prior art and solve at least one technical problem raised in the background technology, the utility model provides an engine cylinder body turning device.

[0006] The technical solution adopted by the utility model to solve its technical problems is: an engine cylinder flipping device described in the utility model includes a flipping frame, one side of the flipping frame is fixedly installed with four electric push rods symmetrically arranged in groups of two, the output end of the electric push rod is fixedly installed with a workbench, the top of the workbench is provided with an engine cylinder; the top of the workbench is provided with a moving component that assists the engine cylinder to slide, and the top of the workbench is provided with a clamping mechanism that cooperates with the engine cylinder to position.

[0007] Furthermore, the moving component includes a through slot opened on the workbench, a rolling column is rotatably connected inside the through slot, and a rubber sleeve is fixedly installed on the surface of the rolling column.

[0008] Furthermore, the clamping mechanism includes two rectangular frames fixedly installed on the surface of the workbench, the two rectangular frames are symmetrical parts with respect to the central axis of the workbench, a rectangular groove is opened inside the rectangular frame, a sliding rod is slidably connected inside the rectangular frame, a triangular clamping plate is fixedly installed at one end of the sliding rod away from the rectangular frame, and a spring fixedly connected to the rectangular frame is arranged on the sliding rod; an air blowing assembly for assisting in cleaning the clamping plate is arranged inside the rectangular frame.

[0009] Furthermore, a threaded rod is threadedly connected to the top of the rectangular frame, and a plurality of threaded grooves are formed on the surface of the sliding rod.

[0010] Furthermore, the blowing assembly includes a sealing plate fixedly mounted on the surface of the sliding rod, the sealing plate and the rectangular groove are sealingly and slidingly connected, one end of the spring is fixedly mounted on the sealing plate, one end of the rectangular frame is fixedly mounted with an air outlet pipe connected to the rectangular groove, and a bracket is fixedly mounted on the top of the splint, and one end of the bracket is fixedly connected to the air outlet pipe.

[0011] Furthermore, the inclined surface of the clamping plate is rotatably connected to a plurality of guide columns, and a gasket is fixedly installed on the bottom of the clamping plate.

[0012] The utility model is beneficial in that:

[0013] 1. The utility model lowers the workbench to the lowest point through the electric push rod, at which time the engine cylinder block can be moved to the workbench, and there is no need to use a sling to assist because the installation point of the engine cylinder block is too high for the turning frame. After the engine cylinder block is placed on the workbench, the electric push rod is started, and the workbench and the engine cylinder block are lifted to a suitable position by the electric push rod. At this time, the bottom of the engine cylinder block is in contact with the rubber sleeve. Since the rubber sleeve is made of flexible material, when the engine cylinder block is pushed, the rolling column and the rubber sleeve drive the engine cylinder block to move, and at the same time, the surface of the engine cylinder block will not be scratched, thereby achieving the purpose of conveniently moving the engine cylinder block while protecting it.

[0014] 2. When the engine cylinder body of the utility model is placed on the workbench, it will first contact the triangular clamping plate and the guide column. The guide column drives the two clamping plates to slide away from each other, thereby increasing the space between the two clamping plates, making it easier to put the engine cylinder body in. At the same time, the guide column can also reduce friction and protect the engine cylinder body. When the clamping plate moves into the rectangular frame, it will drive the slide bar and the sealing plate to move together. The sealing plate is used to squeeze the gas in the rectangular groove, so that the gas in the rectangular groove is sprayed to the clamping plate and the engine cylinder body through the outlet pipe, thereby achieving air blowing cleaning of the clamping plate and the engine cylinder body. Under the action of the spring, the clamping plate is always in contact with the engine cylinder body. When the engine cylinder body is completely placed between the two clamping plates, the gasket at the bottom of the clamping plate plays a role in increasing friction and assisting in fixing the engine cylinder body. At this time, the threaded rod is twisted, so that the threaded rod is fixed in the threaded groove of the slide bar, and then the engine cylinder body is fixed on the workbench, preventing the engine cylinder body from shaking and falling when the workbench moves.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 As shown, an engine cylinder body turning device includes a turning frame 1, one side of the turning frame 1 is fixedly mounted with four electric push rods 3 symmetrically arranged in groups of two, the output end of the electric push rods 3 is fixedly mounted with a workbench 4, and the top of the workbench 4 is provided with an engine cylinder body 2.

[0023] Specifically, a moving assembly for assisting the engine cylinder block 2 to slide is arranged on the top of the workbench 4, and the moving assembly includes a through slot 5 opened on the workbench 4, a rolling column 6 is rotatably connected inside the through slot 5, and a rubber sleeve 7 is fixedly installed on the surface of the rolling column 6.

[0024] During operation, the workbench 4 is lowered to the lowest point by the electric push rod 3, and the engine block 2 can be moved onto the workbench 4 at this time, so there is no need to use a sling to assist because the installation point of the turning frame 1 for the engine block 2 is too high. After the engine block 2 is placed on the workbench 4, the electric push rod 3 is started, and the workbench 4 and the engine block 2 are lifted to a suitable position by the electric push rod 3. At this time, the bottom of the engine block 2 is in contact with the rubber sleeve 7. Since the rubber sleeve 7 is made of a flexible material, when the engine block 2 is pushed, the rolling column 6 and the rubber sleeve 7 drive the engine block 2 to move, and at the same time, the surface of the engine block 2 will not be scratched, thereby achieving the goal of conveniently moving the engine block 2 while also protecting it.

[0025] A clamping mechanism for positioning the engine cylinder block 2 is provided on the top of the workbench 4, and the clamping mechanism includes two rectangular frames 8 fixedly mounted on the surface of the workbench 4, the two rectangular frames 8 are symmetrical parts with respect to the central axis of the workbench 4, a rectangular groove 9 is provided inside the rectangular frame 8, a slide rod 10 is slidably connected inside the rectangular frame 8, a triangular clamping plate 11 is fixedly mounted on one end of the slide rod 10 away from the rectangular frame 8, a plurality of guide columns 18 are rotatably connected to the inclined surface of the clamping plate 11, a gasket 19 is fixedly mounted on the bottom of the clamping plate 11, a spring 12 fixedly connected to the rectangular frame 8 is provided on the slide rod 10, a threaded rod 14 is threadedly connected to the top of the rectangular frame 8, and a plurality of threaded grooves 13 are provided on the surface of the slide rod 10.

[0026] Specifically, a blowing assembly for assisting in cleaning the splint 11 is provided in the rectangular frame 8, and the blowing assembly includes a sealing plate 15 fixedly mounted on the surface of the sliding rod 10, the sealing plate 15 and the rectangular groove 9 are sealingly and slidably connected, one end of the spring 12 is fixedly mounted on the sealing plate 15, an air outlet pipe 16 connected to the rectangular groove 9 is fixedly mounted at one end of the rectangular frame 8, a bracket 17 is fixedly mounted on the top of the splint 11, and one end of the bracket 17 is fixedly connected to the air outlet pipe 16.

[0027] During operation, when the engine block 2 is placed on the workbench 4, it will first contact the triangular clamping plate 11 and the guide column 18. The guide column 18 drives the two clamping plates 11 to slide away from each other, thereby increasing the space between the two clamping plates 11, making it easier to put the engine block 2 in. At the same time, the guide column 18 can also reduce friction and protect the engine block 2. When the clamping plate 11 moves into the rectangular frame 8, it drives the slide bar 10 and the sealing plate 15 to move together. The sealing plate 15 squeezes the gas in the rectangular groove 9, so that the gas in the rectangular groove 9 is sprayed toward the clamping plate 11 and the engine block 2 through the outlet pipe 16, thereby achieving air blowing and cleaning of the clamping plate 11 and the engine block 2. Under the action of the spring 12, the clamping plate 11 is always in contact with the engine block 2. When the engine block 2 is completely placed between the two clamping plates 11, the gasket 19 at the bottom of the clamping plate 11 increases the friction and assists in fixing the engine block 2. At this time, the threaded rod 14 is twisted to fix the threaded rod 14 in the threaded groove 13 of the sliding rod 10, thereby fixing the engine block 2 on the workbench 4 to prevent the engine block 2 from shaking and falling when the workbench 4 moves.

[0028] Working principle: the workbench 4 is lowered to the lowest point by the electric push rod 3, and the engine block 2 can be moved to the workbench 4 at this time, so there is no need to use a sling to assist because the installation point of the turning frame 1 for the engine block 2 is too high. After the engine block 2 is placed on the workbench 4, the electric push rod 3 is started, and the workbench 4 and the engine block 2 are lifted to a suitable position by the electric push rod 3. At this time, the bottom of the engine block 2 is in contact with the rubber sleeve 7. Since the rubber sleeve 7 is made of flexible material, when the engine block 2 is pushed, the rolling column 6 and the rubber sleeve 7 drive the engine block 2 to move, and at the same time, the surface of the engine block 2 will not be scratched, thereby achieving the convenience of moving the engine block 2 while protecting it.

[0029] When the engine block 2 is placed on the workbench 4, it will first contact the triangular clamping plate 11 and the guide column 18. The guide column 18 drives the two clamping plates 11 to slide away from each other, thereby increasing the space between the two clamping plates 11, making it easier to put the engine block 2 in. At the same time, the guide column 18 can also reduce friction and protect the engine block 2. When the clamping plate 11 moves into the rectangular frame 8, it drives the slide bar 10 and the sealing plate 15 to move together. The sealing plate 15 squeezes the gas in the rectangular groove 9, so that the gas in the rectangular groove 9 is sprayed toward the clamping plate 11 and the engine block 2 through the outlet pipe 16, thereby achieving air blowing cleaning of the clamping plate 11 and the engine block 2. Under the action of the spring 12, the clamping plate 11 is always in contact with the engine block 2. When the engine block 2 is completely placed between the two clamping plates 11, the gasket 19 at the bottom of the clamping plate 11 increases the friction and assists in fixing the engine block 2. At this time, the threaded rod 14 is twisted to fix the threaded rod 14 in the threaded groove 13 of the sliding rod 10, thereby fixing the engine block 2 on the workbench 4 to prevent the engine block 2 from shaking and falling when the workbench 4 moves.
