Description

Technical Field

[0001] The utility model relates to the field of cylinder processing equipment, in particular to an inner wall grinding device for processing a cylinder barrel. Background Art

[0002] The cylinder usually refers to a component in an internal combustion engine. It is a hollow cylinder used to accommodate the piston, while the cylinder barrel refers to the wall of the cylinder, which is usually made of metal material. In an internal combustion engine, the cylinder and the cylinder barrel usually work together to generate compressed and burned gases through the up and down movement of the piston to drive the operation of the engine. In the production and processing of the cylinder, it is usually necessary to use a grinding device to grind the inner wall of the cylinder barrel.

[0003] However, in the use of the inner wall grinding device in the prior art, after the cylinder is placed on the device, the motor is first started to drive the grinding disc to rotate, and then the driving structure is used to drive the grinding disc to move downward until it contacts the cylinder, and then the inner wall of the cylinder is ground. Therefore, before the grinding disc contacts the cylinder, the grinding disc idles. In mass production, this part of energy is wasted greatly, and it is difficult to achieve adaptive adjustment of the grinding timing.

[0004] In addition, during the grinding process of the cylinder barrel, debris is generated and falls onto the fixing fixture. After a long period of processing, the debris gradually accumulates on the fixing fixture, resulting in the bottom of the cylinder barrel being uneven due to the debris when it is subsequently placed, which in turn causes vibration during the subsequent grinding of the cylinder barrel, affecting the grinding of the cylinder barrel and making it difficult to clean the debris during the processing;

[0005] In view of the above technical defects, a solution is now proposed. Utility Model Content

[0031] Among them, the rotating rod 1 203 and the rotating rod 3 207 are both screw rods, which form a screw rod transmission structure with the moving block 1 216 and the moving block 220. The threads are not drawn in the figure, and the threads on the rotating rod 1 203 and the rotating rod 3 207 are opposite, so when the moving block 1 216 moves downward, the moving block 2 220 moves upward.

[0035] Embodiment 2:

[0036] This embodiment is used to solve the problem that during the grinding process of the cylinder barrel, debris is generated and falls onto the fixing fixture. After a long period of processing, the debris gradually accumulates on the fixing fixture, resulting in an uneven bottom of the cylinder barrel due to the debris when it is subsequently placed, which in turn causes vibration during the subsequent grinding of the cylinder barrel, affecting the grinding of the cylinder barrel and making it difficult to clean the debris during the processing.

[0037] See also Figure 4 - Figure 5 As shown, the utility model also includes an airbag 214, which is fixedly installed at the bottom of the block 213, and a nozzle 215 is fixedly installed on the fixed plate 3. The airbag 214 is fixedly connected to the nozzle 215 through a hose. When the airbag 214 shrinks, the gas is transported to the nozzle 215 through the hose and is sprayed out by the nozzle 215.

[0038] When the rotating rod three 207 rotates and drives the stopper 213 to move upward, the airbag 214 gradually expands. After the processing is completed, the motor 204 drives the rotating rod 203 to rotate, driving the fixed block 208 and the stopper 213 to reset. During the resetting process of the stopper 213, the airbag 214 is squeezed. At this time, high-speed gas is ejected from the nozzle 215 to clean the debris on the fixed plate 3. There is no need to stop the machine during the cleaning process, thereby realizing the cleaning of debris during the processing.

[0039] A clamping block 301 is movably installed on the fixed plate 3, a cylinder 4 is fixedly installed on the fixed plate 3, the clamping block 301 is located on both sides of the cylinder 4, a sliding groove 302 is opened on the fixed plate 3, the sliding groove 302 is located on both sides of the cylinder 4, a sliding block 303 is movably installed inside the sliding groove 302, a vertical rod 304 is fixedly installed on the top of the sliding block 303, a movable plate 305 is fixedly installed on the top of the vertical rod 304, a fixing bolt 306 is movably installed on the movable plate 305 through a thread, and a clamping block 301 is movably installed on the side of the fixing bolt 306 close to the cylinder 4.

[0040] After placing the cylinder 4 on the fixing plate 3, pull the clamping block 301, tighten the fixing bolt 306, and drive the clamping block 301 to move toward the cylinder 4 until the clamping block 301 fits against the outer wall of the cylinder 4, and use the clamping blocks 301 on both sides of the cylinder 4 to clamp and fix the cylinder 4. At the same time, the clamping block 301 is arc-shaped, which ensures that the cylinder 4 is concentric when fixing the cylinder 4, and avoids position deviation that affects subsequent grinding, thereby realizing rapid fixation of the cylinder 4.

[0041] At the same time, the sliding groove 302 and the sliding block 303 are used to adjust the spacing of the block 301, so as to adapt to cylinder barrels 4 of various sizes, and the application range is wide.

[0042] In combination with Example 1 and Example 2, the stopper 213 and the fixed block 208 are driven to move by a thread, and then the motor 3 211 is started. After the extrusion block 222 contacts the stopper 213, the motor 206 is started to drive the grinding disc 212 to rotate, and the inner wall of the cylinder 4 is polished to reduce the idling time of the grinding disc 212, so that the adaptive adjustment of the polishing timing can be achieved, and the energy loss is effectively reduced to achieve energy saving. After the processing is completed, the motor 1 204 drives the rotating rod 1 203 to rotate, and drives the fixed block 208 and the stopper 213 to reset. During the resetting process of the stopper 213, the airbag 214 is squeezed, and at this time, high-speed gas is ejected from the nozzle 215 to clean the debris on the fixed plate 3, thereby realizing the cleaning of the debris during the processing.

[0043] The working process and principle of the utility model are as follows:

[0044] First, start the motor 1 204 to drive the rotating rod 1 203 and the rotating rod 3 207 to rotate synchronously, and use the thread to drive the stopper 213 and the fixed block 208 to move. At this time, start the motor 3 211 to drive the cross plate 209 to move downward. After the extrusion block 222 contacts the stopper 213, the motor 3 211 stops. At this time, the motor 206 is started to drive the grinding disc 212 to rotate. At the same time, the electric push rod 210 is started to drive the motor 206 to move downward to grind the inner wall of the cylinder 4, reducing the idling time of the grinding disc 212, so as to realize the adaptive adjustment of the grinding timing, effectively reduce energy loss and realize energy saving, and through the setting of the stopper 213, it is suitable for cylinders 4 of various heights, and has a wide range of applications;

[0045] Further, when the rotating rod 3 207 rotates and drives the stopper 213 to move upward, the airbag 214 gradually expands. After the processing is completed, the motor 1 204 drives the rotating rod 1 203 to rotate, driving the fixed block 208 and the stopper 213 to reset. During the reset process of the stopper 213, the airbag 214 is squeezed, and high-speed gas is ejected from the nozzle 215 to clean the debris on the fixed plate 3. There is no need to stop the machine during the cleaning process, so that the debris can be cleaned during the processing.

[0046] Further, after the cylinder barrel 4 is placed on the fixing plate 3, the clamping block 301 is pulled until the clamping block 301 fits against the outer wall of the cylinder barrel 4, and the clamping blocks 301 on both sides of the cylinder barrel 4 are used to clamp and fix the cylinder barrel 4. At the same time, the clamping block 301 is arc-shaped, which ensures that when the cylinder barrel 4 is fixed, the cylinder barrel 4 is concentric, and the position deviation is avoided to affect the subsequent grinding, so as to achieve the rapid fixation of the cylinder barrel 4;

[0047] In summary, the utility model realizes the self-adaptive adjustment of the grinding timing and also cleans the debris during the machining process by means of the adjustment component 2 provided.
