Description

Technical Field

[0001] The present invention relates to the technical field of quenching equipment, and specifically to a quenching device for the production of bimetallic cylinder liners. Background Art

[0002] After the bimetallic cylinder liner is processed, in order to improve the strength of the cylinder liner, it is also necessary to perform quenching treatment on the inner layer cylinder liner.

[0003] Currently, when quenching the cylinder liner, the cylinder liner is generally hoisted by a hoisting device and then placed into the coolant for quenching treatment.

[0004] When using the existing quenching method, the degree of automation is relatively low. Workers need to manually use fixtures to adjust the position of the cylinder liner, and continuously hoist and disassemble the cylinder liner, resulting in a relatively low overall quenching efficiency. And during the quenching process, there are quenching dead angles at the clamping positions on the surface of the cylinder liner by the fixture, and the clamping positions cannot be in full contact with the coolant, so that the surface of the cylinder liner cannot be uniformly quenched in all directions, resulting in a poor quenching effect of the cylinder liner.

Detailed implementation manners

[0027] It should be noted that, without conflict, the embodiments in the present invention and the features in the embodiments can be combined with each other.

[0028] The following describes in detail the specific implementation of the present invention in conjunction with specific embodiments.

[0029] Such as Figure 1 、 Figure 3 、 Figure 7 、 Figure 8As shown in the figure, it is a structural diagram of a quenching device for the production of a bimetallic cylinder liner provided by an embodiment of the present invention, including a quenching tank 1. The top of the quenching tank 1 is provided with an opening structure. Rotating columns 2 are rotatably installed on the opposite side walls of the quenching tank 1. A bearing plate 21 located inside the quenching tank 1 is fixedly installed on the surface of the rotating column 2. A plurality of groups of horizontally arranged columns 3 distributed in a ring are rotatably installed on the surface of the bearing plate 21. A control mechanism 5 is arranged on the surface of the quenching tank 1. The control mechanism 5 includes a circulating quenching component 51 and an automatic feeding component 52. The circulating quenching component 51 is located on the side wall of the quenching tank 1 and is connected to the rotating column 2. The circulating quenching component 51 is used to control the rotating column 2 and the bearing plate 21 to rotate a certain angle at equal intervals in the inner cavity of the quenching tank 1. The automatic feeding component 52 includes conveying rollers 521, a positioning part 522 and a driving part 523. A plurality of groups of conveying rollers 521 are provided. The positioning part 522 is connected to the conveying rollers 521. The positioning part 522 is used to control the plurality of groups of conveying rollers 521 to be arranged side by side outside the quenching tank 1. The driving part 523 is connected to the positioning part 522. When the rotating column 2 and the bearing plate 21 stop rotating, the driving part 523 controls the plurality of groups of conveying rollers 521 to rotate by cooperating with the positioning part 522. A clamping mechanism 4 is arranged on the surface of the horizontally arranged column 3. The clamping mechanism 4 includes a supporting component 41 and a self-rotating component 42. The supporting component 41 is located on the surface of the horizontally arranged column 3. The supporting component 41 is used to install and disassemble the cylinder liner on the surface of the horizontally arranged column 3. The self-rotating component 42 is located on the inner side wall of the quenching tank 1 and is connected to the horizontally arranged column 3. When the bearing plate 21 drives the horizontally arranged column 3 to rotate, the self-rotating component 42 controls the horizontally arranged column 3 to rotate around its own axis while rotating in the inner cavity of the quenching tank 1.

[0030] During use, the inner cavity of the quenching tank 1 is filled with an appropriate amount of coolant. A batch of cylinder liners are placed on the surface of the conveying rollers 521. Multiple groups of conveying rollers 521 can stably support and position the cylinder liners. The circulating quenching assembly 51 controls the rotation of the rotating column 2 by a certain angle. The rotating column 2 drives the bearing plate 21 and the cross column 3 to rotate synchronously by a certain angle, so that a group of cross columns 3 are aligned with the conveying rollers 521. After the cross columns 3 are aligned with the conveying rollers 521, the rotating column 2 stops rotating. The driving part 523 and the positioning part 522 cooperate with each other to control the rotation of multiple groups of conveying rollers 521. When the conveying rollers 521 rotate, they push the cylinder liners towards the bearing plate 21, so that a group of cylinder liners are inserted onto the surface of the cross columns 3. At this time, the supporting assembly 41 can stably support and fix the cylinder liners on the surface of the cross columns 3. After the cylinder liners are inserted onto the surface of the cross columns 3, the conveying rollers 521 stop rotating. The circulating quenching assembly 51 controls the rotating column 2 to rotate by a certain angle again. The rotating column 2 drives the bearing plate 21 and the cross column 3 to rotate synchronously. The cross column 3 drives the cylinder liners to rotate synchronously, so that the cylinder liners rotate into the quenching tank 1 and are immersed in the coolant. The coolant can fully quench the cylinder liners. Repeat this process multiple times. The bearing plate 21 can drive the cylinder liners on the surface of the cross columns 3 to continuously rotate in the inner cavity of the quenching tank 1. When the bearing plate 21 drives the cross column 3 to rotate, the self-rotation assembly 42 can control the cross column 3 to rotate around its own axis. The cross column 3 and the supporting assembly 41 cooperate with each other to change the supporting position of the cylinder liners in the inner cavity of the quenching tank 1, so that the coolant is in full contact with the surface of the cylinder liners, effectively improving the quenching effect of the cylinder liners. The bearing plate 21 drives the cylinder liners to continuously rotate. After the cylinder liners rotate to the outside of the quenching tank 1, the staff can conveniently remove the quenched cylinder liners from the surface of the cross columns 3.

[0031] As Figure 1 , Figure 3 , Figure 4 , Figure 5 shown, as a preferred embodiment of the present invention, one end of the rotating column 2 of the circulating quenching assembly 51 extends to the outside of the quenching tank 1 and is fixedly installed with a fixed gear disk 511. A fixed frame 512 is fixedly installed on the side wall of the quenching tank 1. A motor 513 is fixedly installed on the surface of the fixed frame 512. The output shaft of the motor 513 is fixedly installed with a transmission disk 514. An arc-shaped transmission rack 515 is fixedly installed on the side wall of the transmission disk 514. The transmission rack 515 is meshed and cooperated with the fixed gear disk 511. A limiting part 6 that cooperates with the bearing plate 21 is arranged at the top of the quenching tank 1. When the transmission rack 515 is separated from the fixed gear disk 511, the limiting part 6 is used to control the bearing plate 21 and the rotating column 2 to stop rotating synchronously in the inner cavity of the quenching tank 1, so that a group of cross columns 3 on the surface of the bearing plate 21 are aligned with the conveying rollers 521.

[0032] During use, the motor 513 drives the drive disk 514 to rotate, thereby driving the drive rack 515 to rotate synchronously. When the drive rack 515 comes into contact with the fixed gear disk 511, the drive rack 515 meshes with the fixed gear disk 511 and drives it to rotate. The fixed gear disk 511 drives the rotating column 2 to rotate synchronously. The rotating column 2 drives the bearing disk 21 to rotate synchronously inside the quenching tank 1, thereby adjusting the positions of the cross column 3 and the cylinder liner. The cylinder liner on the surface of the cross column 3 rotates towards the inside of the quenching tank 1, thereby quenching the cylinder liner. When the drive rack 515 continues to rotate and separates from the fixed gear disk 511, at this time, the drive rack 515 releases the restraining force on the fixed gear disk 511. The limiting part 6 controls the bearing disk 21 to stop rotating inside the quenching tank 1. At this time, a group of cross columns 3 on the surface of the bearing disk 21 are aligned with the conveying rollers 521. The driving part 523 and the positioning part 522 cooperate with each other to control the conveying rollers 521 to rotate. The conveying rollers 521 insert the next group of cylinder liners to be quenched onto the surface of the cross column 3, and the batch of cylinder liners can be quenched in sequence.

[0033] As Figure 2 , Figure 3 , Figure 7 shown, as a preferred embodiment of the present invention, the limiting part 6 includes a plurality of first magnetic blocks 61 fixedly installed on the side wall of the bearing disk 21 and distributed at equal intervals in a ring shape. A vertical rod 62 is fixedly installed at the top of the quenching tank 1, and a second magnetic block 63 that cooperates with the first magnetic block 61 is fixedly installed at the top of the vertical rod 62.

[0034] When the drive rack 515 comes into contact with the fixed gear disk 511, the drive rack 515 meshes with the fixed gear disk 511 and drives it to rotate. The fixed gear disk 511 drives the rotating column 2 to rotate synchronously. The rotating column 2 drives the bearing disk 21 to rotate synchronously inside the quenching tank 1. The bearing disk 21 drives the first magnetic blocks 61 to rotate synchronously. At this time, the first magnetic blocks 61 on the surface of the bearing disk 21 are separated from the second magnetic block 63. When the drive rack 515 continues to rotate and separates from the fixed gear disk 511, at this time, the drive rack 515 releases the restraining force on the fixed gear disk 511. Another group of first magnetic blocks 61 on the surface of the bearing disk 21 come into contact with the second magnetic block 63. The first magnetic blocks 61 are attached to the second magnetic block 63 through magnetic attraction and form a whole. At this time, the bearing disk 21 stops rotating in time inside the quenching tank 1, so that a group of cross columns 3 on the surface of the bearing disk 21 are aligned with the cylinder liners on the surface of the conveying rollers 521.

[0035] As Figure 1 , Figure 2 , Figure 3As shown, as a preferred embodiment of the present invention, the positioning portion 522 includes a placement rack 5221 disposed outside the quenching tank 1. The placement rack 5221 is in a long strip-shaped inverted U structure. Support legs 5223 are fixedly installed around the bottom wall of the placement rack 5221. A plurality of groups of bearing columns 5222 distributed side by side are rotatably installed in the placement rack 5221. The conveying rollers 521 are fixedly installed on the surfaces of the bearing columns 5222, and the bearing columns 5222 are connected to the driving portion 523.

[0036] The support legs 5223 support and position the placement rack 5221. The placement rack 5221 and the bearing columns 5222 cooperate with each other to support and position a plurality of groups of conveying rollers 521, and the conveying rollers 521 support and position the cylinder sleeves. After the bearing plate 21 stops rotating and the cross column 3 is aligned with the cylinder sleeves on the surfaces of the conveying rollers 521, the driving portion 523 controls the synchronous rotation of a plurality of groups of bearing columns 5222. The bearing columns 5222 drive the conveying rollers 521 to rotate in the placement rack 5221. A plurality of groups of conveying rollers 521 cooperate with each other to push a plurality of groups of cylinder sleeves towards the bearing plate 21. The group of cylinder sleeves closest to the bearing plate 21 is inserted outside the cross column 3.

[0037] As Figure 1 、 Figure 4 、 Figure 5 As shown, as a preferred embodiment of the present invention, the driving portion 523 includes a vertical plate 5233 fixedly installed at the top of the quenching tank 1. A control column 5234 is rotatably installed on the surface of the vertical plate 5233. A control gear disk 5237 is fixedly installed on the surface of the control column 5234. The control gear disk 5237 is in meshing cooperation with the transmission rack 515. One ends of a plurality of groups of bearing columns 5222 respectively extend outside the placement rack 5221 and are fixedly installed with synchronous gear disks 5231. A synchronous belt 5232 is commonly connected to a plurality of groups of synchronous gear disks 5231. A driven bevel gear disk 5236 is fixedly installed at the end of one group of bearing columns 5222. A driving bevel gear disk 5235 is fixedly installed on the surface of the control column 5234. The driving bevel gear disk 5235 is in meshing connection with the driven bevel gear disk 5236.

[0038] The motor 513 drives the transmission disc 514 to rotate, and then drives the transmission rack 515 to rotate synchronously. When the transmission rack 515 continues to rotate and separates from the fixed tooth disc 511, the transmission rack 515 contacts the control tooth disc 5237. The transmission rack 515 and the control tooth disc 5237 engage and drive to drive the control column 5234 to rotate. The control column 5234 drives the active helical disc 5235 to rotate synchronously. The active helical disc 5235 and the driven helical disc 5236 engage and drive, which can drive a group of bearing columns 5222 to rotate. The bearing columns 5222 drive the synchronous tooth disc 5231 to rotate. Multiple groups of synchronous tooth discs 5231 cooperate with the synchronous belt 5232, which can drive multiple groups of bearing columns 5222 to rotate synchronously. The bearing columns 5222 drive the conveying roller 521 to rotate and then push the cylinder sleeve to move towards the bearing disc 21. After the transmission rack 515 separates from the control tooth disc 5237, the control tooth disc 5237 stops rotating. At this time, the conveying roller 521 stops rotating synchronously.

[0039] As Figure 3 , Figure 7 , Figure 8 shown, as a preferred embodiment of the present invention, the support assembly 41 includes a plurality of support columns 411 fixedly installed on the surface of the cross column 3 and distributed in a ring shape. A receiving hole 412 is formed at one end of the support column 411 away from the cross column 3, and a ball 413 extending to the outside of the support column 411 is placed in the receiving hole 412.

[0040] When the conveying roller 521 rotates and then pushes the cylinder sleeve to move towards the bearing disc 21, the cylinder sleeve closest to the bearing disc 21 is inserted outside the cross column 3. At this time, the ball 413 at the end of the support column 411 contacts the inner wall of the cylinder sleeve. Multiple groups of support columns 411 and balls 413 cooperate with each other, and the cylinder sleeve can be stably supported and positioned outside the cross column 3. The bearing disc 21 drives the cross column 3 to rotate and then drives the cylinder sleeve to rotate synchronously. After the cylinder sleeve rotates into the inner cavity of the quenching tank 1, the coolant can perform efficient quenching treatment on the cylinder sleeve.

[0041] As Figure 2 , Figure 7 , Figure 8 shown, as a preferred embodiment of the present invention, the self-rotation assembly 42 includes a positioning tooth disc 421 fixedly installed at one end of the cross column 3 away from the support column 411 and extending to the other side of the bearing disc 21. An arc-shaped positioning rack 422 is fixedly installed on the inner side wall of the quenching tank 1, and the positioning rack 422 engages with the positioning tooth disc 421.

[0042] When the carrier plate 21 drives the cross column 3 to rotate inside the quenching tank 1, the positioning tooth disc 421 at the end of the cross column 3 rolls along the surface of the positioning rack 422. The positioning tooth disc 421 drives the cross column 3 to rotate around its own axis during rotation. The cross column 3 drives the support column 411 and the ball 413 to rotate synchronously, which can conveniently change the contact position between the ball 413 and the inner wall of the cylinder sleeve, effectively avoiding dead corners at the contact position and affecting the quenching quality.

[0043] As Figure 3 , Figure 5 , Figure 6 shown, as a preferred embodiment of the present invention, a diversion mechanism 7 is arranged inside the quenching tank 1. The diversion mechanism 7 includes a stirring component 71 and a rotating component 72. The stirring component 71 is located inside the quenching tank 1, and the rotating component 72 is connected to the stirring component 71. When the carrier plate 21 rotates inside the quenching tank 1, the stirring component 71 accelerates the flow of the coolant inside the quenching tank 1 by cooperating with the rotating component 72.

[0044] When the carrier plate 21 drives the cylinder sleeve on the surface of the cross column 3 to rotate inside the quenching tank 1, the rotating component 72 and the stirring component 71 cooperate with each other, which can fully stir the coolant inside the quenching tank 1, making the coolant fully contact with the cylinder sleeve, and further improving the quenching effect on the cylinder sleeve.

[0045] As Figure 3 , Figure 5 , Figure 6 shown, as a preferred embodiment of the present invention, the stirring component 71 includes a plurality of fixed rods 711 rotatably installed inside the quenching tank 1 and located outside the carrier plate 21. A plurality of uniformly distributed stirring blades 712 are arranged on the surface of the fixed rods 711.

[0046] When the carrier plate 21 rotates inside the quenching tank 1, the rotating component 72 controls the fixed rods 711 to rotate inside the quenching tank 1. The fixed rods 711 drive the stirring blades 712 to rotate synchronously. The stirring blades 712 fully stir the coolant inside the quenching tank 1, and the coolant accelerates to flow inside the quenching tank 1, effectively improving the quenching effect on the cylinder sleeve.

[0047] As Figure 3 , Figure 5 , Figure 6 shown, as a preferred embodiment of the present invention, the rotating component 72 includes a guiding tooth disc 721 fixedly installed on the surface of the fixed rod 711. A guiding tooth ring 722 is fixedly installed on the annular side wall of the carrier plate 21. The guiding tooth ring 722 is meshed and connected with the guiding tooth disc 721.

[0048] When the carrier plate 21 rotates, it drives the guide gear ring 722 to rotate synchronously. The guide gear ring 722 meshes with the guide gear disc 721 for transmission, which can drive the fixed rod 711 to rotate inside the quenching tank 1.

[0049] The working principle of the present invention is as follows: During use, an appropriate amount of coolant is contained in the inner cavity of the quenching tank 1. A batch of cylinder liners are placed on the surface of the conveying rollers 521. Multiple groups of conveying rollers 521 can stably support and position the cylinder liners. Initially, the first magnetic block 61 adheres to the second magnetic block 63 through magnetic attraction to form a whole. At this time, the carrier plate 21 stops rotating in time inside the quenching tank 1, so that a set of cross columns 3 on the surface of the carrier plate 21 are aligned with the cylinder liners on the surface of the conveying rollers 521.

[0050] The motor 513 drives the transmission disc 514 to rotate, and then drives the transmission rack 515 to rotate synchronously. The transmission rack 515 contacts the control gear disc 5237. The transmission rack 515 meshes with the control gear disc 5237 for transmission, which drives the control column 5234 to rotate. The control column 5234 drives the active bevel gear disc 5235 to rotate synchronously. The active bevel gear disc 5235 meshes with the driven bevel gear disc 5236 for transmission, which can drive a set of load-bearing columns 5222 to rotate. The load-bearing columns 5222 drive the synchronous gear disc 5231 to rotate. Multiple groups of synchronous gear discs 5231 cooperate with the synchronous belt 5232, which can drive multiple groups of load-bearing columns 5222 to rotate synchronously. The load-bearing columns 5222 drive the conveying rollers 521 to rotate, thereby pushing the cylinder liners towards the carrier plate 21. The set of cylinder liners closest to the carrier plate 21 are inserted outside the cross columns 3. At this time, the balls 413 at the ends of the support columns 411 contact the inner wall of the cylinder liners. Multiple groups of support columns 411 and the balls 413 cooperate with each other to stably support and position the cylinder liners outside the cross columns 3. After the transmission rack 515 separates from the control gear disc 5237, the control gear disc 5237 stops rotating. At this time, the conveying rollers 521 stop rotating synchronously.

[0051] The motor 513 drives the transmission disk 514 to rotate, and then drives the transmission rack 515 to continuously rotate. When the transmission rack 515 contacts the fixed gear disk 511, the transmission rack 515 meshes with the fixed gear disk 511 to drive the fixed gear disk 511 to rotate. The fixed gear disk 511 drives the rotating column 2 to rotate synchronously. The rotating column 2 drives the bearing disk 21 to rotate synchronously in the inner cavity of the quenching tank 1, thereby adjusting the positions of the cross column 3 and the cylinder liner. The cylinder liner on the surface of the cross column 3 rotates towards the inner cavity of the quenching tank 1, and then the cylinder liner is quenched. When the transmission rack 515 continuously rotates and separates from the fixed gear disk 511, at this time, the transmission rack 515 releases the restraining force on the fixed gear disk 511. Another set of first magnetic blocks 61 on the surface of the bearing disk 21 contacts the second magnetic blocks 63. The first magnetic blocks 61 are attached to the second magnetic blocks 63 through magnetic attraction to form a whole. At this time, the bearing disk 21 stops rotating in the inner cavity of the quenching tank 1 in time, so that a set of cross columns 3 on the surface of the bearing disk 21 are aligned with the cylinder liners on the surface of the conveying rollers 521. Repeating this process multiple times, the bearing disk 21 can drive the cylinder liners on the surfaces of multiple sets of cross columns 3 to continuously rotate in the inner cavity of the quenching tank 1, and can continuously and automatically quench multiple sets of cylinder liners. After the cylinder liner rotates to the outside of the quenching tank 1, the staff can conveniently remove the quenched cylinder liner from the surface of the cross column 3.

[0052] When the bearing disk 21 drives the cross column 3 to rotate in the inner cavity of the quenching tank 1, the positioning gear disk 421 at the end of the cross column 3 rolls along the surface of the positioning rack 422. The positioning gear disk 421 drives the cross column 3 to rotate around its own axis during rotation. The cross column 3 drives the support column 411 and the ball 413 to rotate synchronously, which can conveniently change the contact position between the ball 413 and the inner wall of the cylinder liner, effectively avoiding dead corners at the contact position and affecting the quenching quality.

[0053] The above has described the preferred embodiments of the present invention in detail, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those of ordinary skill in the art, various changes can be made without departing from the gist of the present invention.
