Description

Technical Field

[0002] Cylinder liner is the abbreviation of cylinder liner. It is a cylindrical part located in the cylinder of an internal combustion engine. Its main function is to form a combustion chamber together with the piston and piston ring, and to guide the movement of the piston. It has the advantages of high density, high strength, and strong stability in use. When processing cylinder liner, such as surface grinding by a grinder, the workbench will inevitably generate vibrations from various sources, which will be transmitted to the cylinder liner being processed, affecting the processing accuracy and quality, and then affecting the processing efficiency. The traditional shock-absorbing method for cylinder liner processing mostly uses simple springs or rubber pads placed at the connection between the machine tool and the ground or the machine tool parts. Although it has a certain buffering capacity, it has limited absorption of high-frequency and large-amplitude vibrations, poor durability, and is easy to affect the accuracy and work efficiency of cylinder liner processing.

[0003] To this end, the Chinese invention patent with patent number CN108799404A discloses a shock-absorbing CNC machine tool base, in which a shock-absorbing box is fixed in the ground support frame, and a plurality of through holes communicating with the interior of the shock-absorbing box are opened on the upper end surface of the shock-absorbing box, and a support column is inserted into each through hole; the upper end of each support column is fixedly connected to the bottom of the machine tool support platform, and the lower end of each support column is fixedly connected to the upper end of the support block, and the lower end of each support block is connected to the bottom of the shock-absorbing box through a support spring; a plurality of horizontal sliding seats are also arranged around each support block, and each horizontal sliding seat is slidably connected to the side wall of the support block, and adjacent horizontal sliding seats corresponding to different support blocks are also connected through horizontal springs, which can effectively absorb the vibration generated during the operation of the machine tool and have a good effect of absorbing vibration energy.

[0004] However, the above-mentioned device will experience rapid spring wear after long-term use and is prone to loosening. Once the spring becomes loose, it will not only affect its shock absorption quality and effect, but also easily cause the workbench to shake. It has poor durability and wears too quickly, affecting processing quality and efficiency. Summary of the invention

[0040] By adopting the above scheme, the longitudinal vibration force exerted on the workbench 2 can be easily buffered and absorbed through the main shock-absorbing mechanism, and the lateral vibration force exerted on the workbench 2 can be easily buffered and absorbed through the side shock-absorbing mechanism, thereby realizing a multi-directional anti-vibration effect. When the main shock-absorbing mechanism and the side shock-absorbing mechanism become loose after long-term use, the tightening turn plate 8 can be rotated upward by the tightening mechanism to drive the fixed plate 4 to move toward the base plate 3 to a certain distance, thereby realizing the tightening effect of the rubber tube 6, the buffer airbag 7 and the transverse buffer spring 503, ensuring the anti-vibration effect and quality of the device, effectively improving the anti-vibration performance of the cylinder liner during processing, enhancing the durability of the shock-absorbing device, extending its service life, and ensuring the processing accuracy and quality, thereby improving work efficiency.

[0041] Specifically, the upper and lower ends of the rubber tube 6 are fixedly connected with rubber blocks 601, the end faces of the rubber blocks 601 are fixedly connected with slides 603, the middle parts of the two rubber blocks 601 are respectively inserted into the fixed plate 4 and the base plate 3, a vertical buffer spring 604 is fixedly connected between the rubber blocks 601, and the vertical buffer spring 604 is sleeved on the rubber tube 6.

[0042] By adopting the above scheme, the sliding piece 603 is helpful to reduce the friction between the rubber block 601, the fixed plate 4 and the base plate 3, so that the rubber block 601 can be inserted into the fixed plate 4 and the base plate 3 more conveniently, thereby effectively improving the stability of the installation structure of the main shock absorbing mechanism, and effectively enhancing the seismic performance of the bottom of the workbench 2 through the rubber tube 6, the rubber block 601 and the vertical buffer spring 604.

The inner top of the lower cover plate 702 is fixedly connected with a support rod 703, and the support rod 703 is slidably connected to the top of the tightening turn plate 8.

[0046] The above scheme effectively improves the stability of the installation structure of the cushion airbag 7. When the tightening turntable 8 is rotated upward, the tightening turntable can lift the lower cover plate 702 through the support rod 703, thereby facilitating the tightening of the cushion airbag 7, thereby ensuring its anti-seismic performance and extending its service life.

[0047] Specifically, a threaded rod 803 is fixedly connected to the middle part of the base plate 3, a stop plate 804 is fixedly connected to the top of the threaded rod 803, the middle part of the tightening turn plate 8 is threadedly sleeved on the threaded rod 803, the top and bottom of the tightening turn plate 8 are connected to the first swivel 801 and the second swivel 802 through bearings, the support rod 703 is fixedly connected to the first swivel 801, and the lower end of the nylon rope 9 is fixedly connected to the second swivel 802.

[0057] Specifically, a positioning ring 201 is fixedly connected to the inner top of the workbench 2 .

[0058] The above solution facilitates the stable insertion of the cylinder sleeve onto the workbench 2, facilitates the positioning of the cylinder sleeve, and facilitates the processing operation.

[0059] Working principle of the present invention:

[0060] When in use, the cylinder sleeve to be processed is placed on the workbench 2 and inserted into the positioning ring 201, and then the cylinder sleeve is fixed with a clamping device to perform cutting, drilling, grinding and other processing operations. At this time, the vibration force generated during the processing will be multiple buffered and absorbed by the main shock absorbing mechanism and the side shock absorbing mechanism, that is, the longitudinal vibration force exerted on the workbench 2 is buffered and absorbed by the cooperation of the buffer airbag 7, the vertical buffer spring 604, the rubber tube 6 and the rubber block 601, and then the vibration force is further absorbed by the support plate 5, the horizontal buffer spring 503, the slide frame 502, the guide slider 504 and the guide slide groove 505, thereby achieving a multi-directional anti-seismic effect; when the shock absorbing mechanism becomes loose due to long-term use, the tightening rotating plate 8 is rotated upward to drive the support rod 70 3. The lower cover plate 702 pushes the buffer airbag 7 upward, and at the same time pulls the nylon rope 9 upward, driving the limit plate 902 to push the fixed plate 4 downward, so that the fixed plate 4 tightens the rubber tube 6 and the vertical buffer spring 604, and the fixed plate 4 pushes the support plate 5 to tighten the horizontal buffer spring 503, thereby effectively ensuring the seismic quality, improving the durability of the shock absorbing device, and extending its service life; when the main shock absorbing mechanism needs to be replaced, first twist the limit plate 902 to disengage from the nylon rope 9, so that the nylon rope 9 is separated from the rubber tube 6 and the base plate 3, and the buffer airbag 7 is deflated, so that the positioning block 704 is driven to disengage from the positioning plug 11, and then the staff takes the rubber block 601 and slides it out of the positioning plug 11, which is flexible and convenient to disassemble and use.
