Description

Technical Field

[0001] The invention relates to the technical field of cylinder liner processing devices, and in particular to a cylinder liner local deformation processing device. Background Art

[0002] As one of the key components of the engine, the performance of the cylinder liner directly affects the efficiency and life of the engine. Under high temperature and high pressure working environment, the upper end of the cylinder liner inner hole is prone to form carbon deposits due to the deposits produced by combustion. These carbon deposits will cause local overheating, accelerate the wear of the piston and cylinder liner, and shorten the service life of the engine.

[0003] At present, the common method to remove carbon deposits on the upper end of the inner hole of the cylinder liner is to reduce the size of the upper end of the inner hole and use the extrusion effect to scrape off the carbon deposits. However, the traditional honing method cannot achieve local deformation of the inner hole of the cylinder liner, so it is necessary to install a decarbonizing ring on the upper end of the inner hole. This decarbonizing ring requires high machining accuracy and is not easy to machine, resulting in low machining efficiency. In addition, the existing machining methods often require manual intervention, and it is difficult to detect the thickness of the hardened layer in real time during the machining process, resulting in the cylinder liner may need to be repeatedly processed, thus affecting production efficiency and machining quality.

[0004] Although the existing cylinder liner processing technology can meet the needs to a certain extent, there are still some obvious defects. First, the processing precision of the carbon ring removal is high and the processing difficulty is great, resulting in low production efficiency. Secondly, the existing technology cannot effectively remove the oil stains on the inner surface of the cylinder liner during the processing process, and these oil stains will affect the effect of the high-frequency quenching operation. In addition, the thickness of the hardened layer is difficult to detect during the processing process, resulting in the cylinder liner may need to be reworked multiple times, which not only reduces the processing efficiency, but also may affect the processing quality of the cylinder liner.

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 As shown, a cylinder liner local deformation processing device includes a base 1, a support fixing structure 5 is fixedly connected to the front upper end of the base 1, a processing structure 4 is fixedly connected to the rear upper end of the base 1 and the rear end of the support fixing structure 5, a coolant supply tank 2 is fixedly connected to the rear upper end of the base 1 and the rear end of the processing structure 4, and a central drive cabinet 3 fixedly connected to the processing structure 4 is fixedly connected to the upper right end of the coolant supply tank 2.

[0035] It should be particularly noted that the above-mentioned central drive cabinet 3 is a conventional control device, which is equipped with a high-frequency generator and a circulating pump. It can provide high-frequency current to the coil connected to it, so that it generates a magnetic field, thereby utilizing the thermal effect of the magnetic field to heat the inner surface of the cylinder liner. At the same time, it can also extract the coolant in the coolant supply tank 2 and provide it to the processing structure 4 for cooling. This structure has been widely used in the prior art. In the present invention, it is only used to realize the functions of providing a high-frequency magnetic field and providing coolant, and its internal structure, operating principle, wiring, and control method are not described in detail.

[0036] Further, in order to realize the local deformation processing of the cylinder liner, refer to Figure 2 The processing structure 4 includes a driving seat 41 fixedly connected to the rear portion of the upper end of the base 1, a motor 411 is fixedly connected to the upper end of the driving seat 41, a slide groove 413 is provided at the front end of the driving seat 41, a threaded rod 412 which is rotatably connected to the inner surface of the slide groove 413 and is transmission-connected to the motor 411, a processing auxiliary component 42 which is slidably connected to the inner surface of the slide groove 413 is threadedly connected to the outer surface of the threaded rod 412, and a processing component 43 is provided at the lower end of the processing auxiliary component 42.

[0037] The driving seat 41 drives the threaded rod 412 to rotate, thereby utilizing the action of the threaded rod 412 and the processing auxiliary component 42 to drive the processing auxiliary component 42 to slide up and down in the slide groove 413, thereby compressing and fixing the upper part of the cylinder sleeve, and also allowing the processing component 43 to enter the interior of the cylinder sleeve to perform deformation processing on it.

[0038] Further, in order to realize local deformation processing of the cylinder liner by high frequency quenching, refer to Figure 3 and Figure 4 The processing component 43 includes a support block 431 fixedly connected to the lower end of the sliding tube 423. The support block 431 is hourglass-shaped and its two opposite inclined surfaces are both annularly distributed and fixedly connected with a plurality of spray pipes 433 connected with its inner cavity. The upper and lower groups of spray pipes 433 face opposite directions. An electromagnetic heating ring 432 is fixedly connected to the middle of the outer surface of the support block 431. A connecting pipe 434 connected to the central drive cabinet 3 is fixedly connected to the upper end of the support block 431. A water pipe connected to the plurality of spray pipes 433 and a wire connected to the electromagnetic heating ring 432 are arranged in the connecting pipe 434.

[0039] The support block 431 is used to provide an installation place for the electromagnetic heating ring 432 and the spray pipe 433. The water pipe inside the upper connecting pipe 434 is connected to the spray pipe 433 to provide cooling water, and the wire inside the connecting pipe 434 is connected to the electromagnetic heating ring 432 to emit a magnetic field through the electromagnetic heating ring 432 to heat the local area of ​​the inner surface of the cylinder liner. This heating technology has been widely used in the prior art, and its specific operating principle and structure will no longer be displayed and explained in the present invention.

[0040] Furthermore, in order to clamp and fix the cylinder sleeve during the processing to prevent it from being deformed and shifted due to the impact of water flow, refer to Figure 2 The supporting and fixing structure 5 includes an installation frame 51 fixedly connected to the front part of the upper end of the base 1, and a supporting driving component 54 is fixedly connected to the bottom wall of the inner surface of the installation frame 51. A supporting platform 52 slidably connected to the upper end of the installation frame 51 is arranged on the upper end of the supporting and driving component 54. Horizontal limiting grooves 521 are arranged in an annular distribution on the upper end of the support platform 52. A plurality of fixing components 53 slidably connected to the inner surfaces of adjacent horizontal limiting grooves 521 are arranged in an annular distribution on the upper end of the installation frame 51. A plurality of guide pipes 523 are arranged in the inner cavity of the support platform 52. The plurality of guide pipes 523 are connected to each other, and the guide pipe 523 in the innermost circle is provided with a connecting pipe 522 connected to the horizontal limiting groove 521, and the inner surface of the guide pipe 523 in the outermost circle is fixedly connected with a connecting pipe 2 524 connected to the central driving cabinet 3.

[0041] When the cylinder liner is placed on the support platform 52, the fixing component 53 and the support drive component 54 are used to cooperate to drive the fixing component 53 to expand outward, thereby preliminarily fixing the cylinder liner to ensure that the processing component 43 can smoothly enter the inner side of the cylinder liner during the descent process. At the same time, the guide pipe 523, the connecting pipe 522 and the connecting pipe 2 524 opened in the support platform 52 are used to promote the circulation of the coolant and reduce the consumption rate of the coolant.

[0042] During the operation of this embodiment, the fixing component 53 and the support drive component 54 are used to cooperate to drive the fixing component 53 to expand outward, thereby preliminarily fixing the cylinder liner to ensure that the processing component 43 can smoothly enter the inner side of the cylinder liner during the descent process. At the same time, the processing auxiliary component 42 and the support platform 52 are further used to prompt the support drive component 54 to convert the preliminary fixation into forced fixation on the fixing component 53, thereby avoiding the shaking and swinging of the cylinder liner due to the continuous impact of the coolant during the deformation process, thereby affecting its stability and the accuracy of the deformation process.

[0043] Embodiment 2. Based on embodiment 1, this embodiment drives the driving shaft 4223 to rotate through the motor 2 4221, and drives the ball rod 4225 to move in the vertical limit groove 4226 through the curved slide groove 4224 provided on the driving shaft 4223. Through the path setting of the threaded block 424, the vertical limit groove 4226 is prompted to present an upward-pause-downward-pause-downward movement trend, thereby realizing slope processing of the inner surface of the cylinder sleeve, thereby achieving the effect of its local deformation processing, increasing the processing rate, reducing the frequency of repeated processing, and thus improving the processing efficiency.

[0044] Specifically, to achieve the drive of deformation processing, refer to Figure 4 The processing auxiliary component 42 includes a threaded block 424 that is slidably connected to the inner surface of the slide groove 413 and threadedly connected to the outer surface of the threaded rod 412. The front end of the threaded block 424 is fixedly connected to a compression plate 421. The inner surface of the compression plate 421 is slidably connected to a sliding tube 423. The lower end of the sliding tube 423 is fixedly connected to the processing component 43. The rear part of the upper end of the compression plate 421 is fixedly connected to a reciprocating drive part 422 that is fixedly connected to the outer surface of the sliding tube 423.

[0045] The main purpose of deformation processing is to form a bulge on the inner surface of the cylinder liner, so that it can scrape off the oil and other attachments on the surface of the cylinder piston during the movement of the piston. Therefore, deformation processing requires forming a slope-shaped bulge on the upper part of the inner surface of the cylinder liner;

[0046] The sliding tube 423 slides on the compression plate 421 and is driven by the reciprocating drive part 422, thereby driving the sliding tube 423 to present an upward-pause-downward-pause-downward movement trend, thereby achieving a higher processing frequency in the middle than the processing frequency on the upper and lower sides, so that the number of hardened layers in the middle is greater, thereby achieving a bulge in the middle and forming relatively smooth slopes on both sides.

[0047] Further, in order to realize driving the processing assembly 43 to move back and forth along a predetermined trajectory, refer to Figure 5 The reciprocating driving part 422 includes a limit cover 4222 fixedly connected to the upper end of the compression plate 421, a motor 2 4221 fixedly connected to the upper end of the limit cover 4222, and an output end of the motor 2 4221 passes through the upper end of the limit cover 4222 and extends to the inner cavity of the limit cover 4222 and is fixedly connected to a driving shaft 4223. The outer surface of the driving shaft 4223 is provided with a curved slide 4224 connected end to end, and the front and rear paths of the curved slide 4224 are respectively V-shaped and the left and right sides are both horizontal paths. The inner surface of the curved slide 4224 is slidably connected to a ball rod 4225 fixedly connected to the rear of the outer surface of the sliding tube 423, and the front surface of the outer surface of the limit cover 4222 is provided with a vertical limit groove 4226 slidably connected to the outer surface of the ball rod 4225.

[0048] Motor 2 4221 drives the driving shaft 4223 to rotate. During the rotation of the driving shaft 4223, due to the guiding effect of the threaded block 424 and the limiting effect of the vertical limiting groove 4226, the height of the ball rod 4225 will change, thereby driving the sliding tube 423 to move upward with the ball rod 4225. During this process, the height change of the ball rod 4225 will change synchronously with the path change of the curved sliding groove 4224, thereby realizing the movement trend of upward-pause-downward-pause-downward, so as to achieve the purpose of forming a slope bulge.

[0049] Embodiment 3: Based on embodiment 2, this embodiment further uses the gravity of the cylinder liner to compress the compression spring 3 543 when the cylinder liner is placed on the support platform 52, so that the central axis 544 rises relative to the support platform 52. During this process, the connecting rod 545 is transformed from an inclined direction to a horizontal direction, thereby pushing the inner ring fixing portion 531 to move toward the inner surface of the cylinder liner, and simultaneously using the cable 533 to drive the skirt fixing portion 532 to move toward the skirt of the cylinder liner, thereby preliminarily centering and fixing the cylinder liner, so that the processing component 43 can just enter the middle part of the inner side of the cylinder liner during the falling process, avoiding collision and without the need for additional manual fixing; at the same time, after the processing is completed, the cylinder liner can be directly lifted up to be taken out, and no additional operation is required to release the fixation.

[0050] Specifically, in order to drive the fixing assembly 53 so that it fits on the skirt and inner surface of the cylinder liner, refer to Figure 6 The support driving assembly 54 includes a plurality of spring telescopic rods 541 which are annularly distributed and fixedly connected to the bottom wall of the inner cavity of the mounting frame 51, and a base 542 which is fixedly connected to the bottom wall of the inner cavity of the mounting frame 51. The upper end of the base 542 is fixedly connected to a central axis 544. The outer surface of the central axis 544 is provided with a second slide groove 546 which is slidably connected to the support platform 52. A plurality of connecting rod grooves 547 are annularly distributed on the upper portion of the outer surface of the central axis 544. The lower portions of the inner surfaces of the plurality of connecting rod grooves 547 are rotatably connected to connecting rods 545 which are rotatably connected to adjacent fixed assemblies 53. The upper end of the base 542 is fixedly connected to a compression spring three 543 which is sleeved on the outer surface of the central axis 544 and fixedly connected to the lower end of the support platform 52.

[0051] After the cylinder liner is placed on the support platform 52 , the support platform 52 will be pressed to move downward, thereby causing the relative height between the central axis 544 and the fixing assembly 53 to change.

[0052] Further, in order to achieve the preliminary fixation of the inner surface and skirt of the cylinder liner, refer to Figure 7 and Figure 8The fixing assembly 53 includes an inner ring fixing portion 531 rotatably connected to the adjacent connecting rod 545, and one end of the inner ring fixing portion 531 close to the central axis 544 is fixedly connected to a cable 533, and one end of the cable 533 away from the inner ring fixing portion 531 bypasses the slip ring at the front of the horizontal limit groove 521, passes through the inner ring fixing portion 531, extends to the end of the inner ring fixing portion 531 away from the central axis 544 and is fixedly connected to a skirt fixing portion 532, and both the inner ring fixing portion 531 and the skirt fixing portion 532 are slidably connected to the inner surface of the adjacent horizontal limit groove 521.

[0053] When the height of the center axis 544 changes relative to the fixed assembly 53, the connecting rod 545 will push the inner ring fixing portion 531 to move toward the inner surface of the cylinder liner, and simultaneously use the cable 533 to pull the skirt fixing portion 532 to move toward the outer skirt of the cylinder liner until the inner ring fixing portion 531 and the skirt fixing portion 532 are both in contact with the cylinder liner. At this time, the cylinder liner is initially fixed above the support platform 52. At the same time, since the inner ring fixing portions 531 on all sides move synchronously, the centering action will be completed during the fixing process.

[0054] Embodiment 4. Based on embodiment 3, this embodiment utilizes the pressure of the pressure plate 421 to force the support platform 52 to continue to descend, so that the connecting rod 545 continues to push the inner ring fixing portion 531 to move outward, thereby converting the elastic pressure provided by the tension spring 5315 into the forced fixation provided by the direct contact of the L-shaped plate 5312 and the contact plate 5313. At the same time, the external L-shaped block 5321 will pull the limit frame 5324 into the comb plate 5326 due to the tightening of the cable 533, thereby blocking the movement path of the L-shaped block 5321 and forcibly fixing the skirt, thereby avoiding the cylinder liner shaking due to the continuous impact of the coolant during the processing, affecting the processing accuracy.

[0055] Further, in order to realize the forced fixation of the inner surface of the cylinder liner, refer to Figure 8 The inner ring fixing portion 531 includes a pulley 5311 that is slidably connected to the inner surface of the horizontal limit groove 521 and connected to the cable 533. The upper end of the pulley 5311 is fixedly connected to an L-shaped plate 5312 that is rotatably connected to the adjacent connecting rod 545. A contact plate 5313 is provided at the end of the L-shaped plate 5312 away from the central axis 544. The end of the contact plate 5313 close to the L-shaped plate 5312 is symmetrically fixedly connected to the limit rods 5314 that are slidably connected to the L-shaped plate 5312. The ends of the two limit rods 5314 away from the central axis 544 are fixedly connected to tension springs 5315 that are fixedly connected to the inner arc surface of the L-shaped plate 5312.

[0056] The L-shaped plate 5312 is pushed by the connecting rod 545 and gradually pushes the contact plate 5313 to contact the inner surface of the cylinder sleeve through the tension spring 5315. At this time, the cylinder sleeve is in an elastic fixed state, and the cylinder sleeve will not shake without excessive external force.

[0057] When the connecting rod 545 continues to push the L-shaped plate 5312 , the tension spring 5315 reaches its force limit, and the L-shaped plate 5312 fits together with the contact plate 5313 . At this time, the cylinder sleeve no longer has elastic space and is completely fixed above the support platform 52 .

[0058] Further, in order to realize the forced fixation of the cylinder liner skirt, refer to Fig. 9 and Fig.10 The skirt fixing part 532 includes a T-shaped slide 5322 and an L-shaped block 5321. The lower part of the inner surface of the T-shaped slide 5322 is slidably connected to a limiting frame 5324. The end of the limiting frame 5324 close to the pulley 5311 is fixedly connected to the cable 533. The end of the limiting frame 5324 close to the cable 533 is fixedly connected to a compression spring 2 5327 fixedly connected to the inner wall of the T-shaped slide 5322. The side of the limiting frame 5324 close to the cable 533 is symmetrically slidably connected to a spring lock tongue 5325. The upper part of the inner surface of the T-shaped slide 5322 is slidably connected to the outer surface of the vertical part of the L-shaped block 5321. The lower end of the vertical part of the L-shaped block 5321 is fixedly connected to a compression spring 1 5323 fixedly connected to the inner wall of the T-shaped slide 5322 through a limiting plate. The lower end of the L-shaped block 5321 is symmetrically fixedly connected to a comb plate 5326 overlapping the arc surface part of the spring lock tongue 5325.

[0059] When the L-shaped plate 5312 is continuously pushed by the connecting rod 545, the cable 533 is also continuously tightened. At this time, the pulling force of the cable 533 exceeds the reaction force provided by the second compression spring 5327. The second compression spring 5327 begins to compress, and the limit frame 5324 slides in the L-shaped block 5321 toward the inner ring fixing portion 531. As a result, the arc surface of the spring locking tongue 5325 enters the comb-shaped plate 5326, and the comb-shaped plate 5326 is stuck and cannot move up and down.

[0060] When the compression plate 421 leaves the upper part of the cylinder sleeve, the central axis 544 will move upward under the action of the compression spring three 543. At this time, the connecting rod 545 will pull the inner ring fixing part 531 to reset, thereby restoring the elastic fixed state. The cable 533 will reset following the movement of the pulley 5311. The limit frame 5324 will slide in the direction away from the inner ring fixing part 531 under the action of the compression spring two 5327. At this time, the arc surface of the spring lock tongue 5325 overlaps with the teeth of the comb plate 5326, and the comb plate 5326 can move freely up and down.
