Abstract
Description
Technical Field
[0001] This invention relates to the field of bearing processing technology, specifically to a bearing processing equipment for internal combustion engines. Background Technology
[0002] The bearing shell is the part of the sliding bearing that contacts the journal. It is shaped like a tile-like semi-cylindrical surface and is very smooth. It is generally made of wear-resistant materials such as bronze and anti-friction alloys. In special cases, it can be made of wood, engineering plastics, or rubber. There are two types of bearing shells: integral and split. Integral bearing shells are usually called bushings. Integral bearing shells are available with or without oil grooves. The bearing shell and the journal are fitted with clearance and generally do not rotate with the shaft. The bearing shell of an internal combustion engine is a key component in the sliding bearing of an internal combustion engine. It is usually a tile-shaped semi-cylindrical surface and is mainly used to support the crankshaft and reduce its friction and wear.
[0003] Existing internal combustion engine bearings generally consist of two pieces, upper and lower, installed at the journal position of the crankshaft. However, due to their semi-circular shape, existing equipment can only perform grinding on one side when grinding the bearings. Furthermore, the clamping part of the bearing may be obstructed, making it impossible to grind that area. The bearing position needs to be repeatedly adjusted for grinding, resulting in low grinding efficiency. Summary of the Invention

[0009] Preferably, the outer surface of the lower grinding roller is slidably fitted with a plurality of side grinding plates that fit against the side of the semi-annular bearing.

The side grinding plates are slidably disposed in the cavity and the slides. The top of the processing frame is provided with a spacing adjustment frame for adjusting the spacing between the plurality of side grinding plates.
[0010] Preferably, the spacing adjustment frame has strip-shaped slides at positions opposite to several side grinding plates, and several strip-shaped slides on both sides are arranged in an inverted V-shape. A sliding guide rod is slidably installed inside the strip-shaped slide. A limit anti-detachment plate is fixedly installed at the bottom end of the sliding guide rod, and a support bracket is fixedly installed at the top end of the sliding guide rod.

[0014] Preferably, a plurality of electric push rods are fixedly mounted on the surface of the processing frame, and the output ends of the plurality of electric push rods are all fixedly connected to the adjustment connecting frame.
[0015] Preferably, both the upper conveying roller and the lower conveying roller are provided with anti-slip ribs on their outer surfaces, and the anti-slip ribs are made of an elastic and deformable material.
[0016] Working principle: The semi-annular bearing is placed above the lower conveyor roller. Then, the drive cylinder is opened by controlling the cylinder to drive the support frame to move downward. The downward movement of the support frame drives the upper conveyor roller to move upward synchronously, so that the upper conveyor roller can fit into the surface of the semi-annular bearing. The upper and lower conveyor rollers are then controlled to start rotating, thus realizing the conveying of the semi-annular bearing. The electric push rod is activated, which drives the adjusting connecting frame to move upward. The movement of the adjusting connecting frame drives the lower grinding roller to move upward synchronously, so that the lower grinding roller is in contact with the bottom of the semi-annular bearing. The adjusting thread rod is rotated, which drives the adjusting thread rod to rotate. The rotation of the adjusting thread rod causes the adjusting slider to move downward. The movement of the adjusting slider can drive the upper grinding roller to move synchronously, so that the upper grinding roller is in contact with the surface of the semi-annular bearing. The control starts the drive push rod, which drives the spacing adjustment frame to move. During the movement of the spacing adjustment frame, multiple strip slides drive multiple sliding guide rods to move closer or further apart. The movement of the sliding guide rods drives the side grinding plates to move synchronously through the support bracket, thereby adjusting the position between the multiple side grinding plates. The multiple grinding rollers are adjusted according to the size of the semi-annular bearing, so that the side grinding plates are adjusted to fit against the side of the semi-annular bearing. Then, control the operation of the upper and lower grinding rollers to achieve the grinding of the semi-annular bearing. While the lower grinding roller rotates and grinds, it can drive the side grinding plate to move synchronously to grind, thus achieving multi-directional synchronous grinding of the semi-annular bearing. When the air pump is turned on, it can use the multi-port pipe to extract air from the surface of the processing frame, drawing the debris generated during the grinding process into the dust collection box. The dust collection rack collects the debris uniformly, and the fixed support plate allows the adjusting guide to move synchronously with the telescopic air supply pipe during the movement of the guide, enabling the connecting air pipe to perform comprehensive dust extraction.
[0017] This invention provides a machining equipment for internal combustion engine bearings. It has the following beneficial effects: 1. This invention, by setting up a drive cylinder, a support crossbeam, an upper conveying roller, and a lower conveying roller, utilizes the rotational cooperation of the upper and lower conveying rollers to achieve the conveying of semi-annular bearing shells, causing the semi-annular bearing shells to rotate on their own. This eliminates the need for repeated manual adjustments by operators, enabling multi-directional grinding of the surface of the semi-annular bearing shells. It effectively avoids the problem of obstruction at the clamping point. The drive cylinder moves the support crossbeam up and down, adjusting the distance between the upper and lower conveying rollers to adapt to the processing requirements of semi-annular bearing shells of different thicknesses, thus improving the versatility of the equipment.
[0018] 2. This invention, by setting up an upper grinding roller and a lower grinding roller, utilizes the rotation of the upper and lower grinding rollers to grind the surface of the semi-annular bearing bush. It can simultaneously grind the upper and lower surfaces of the semi-annular bearing bush. In conjunction with the upper and lower conveying rollers, it can achieve continuous grinding without the need to repeatedly stop the machine to adjust the position of the bearing bush, thus improving work efficiency.
[0019] 3. This invention, by setting a side grinding plate and a spacing adjustment frame, utilizes the side grinding plate to grind the side of the semi-annular bearing. The side grinding plate slides within the cavity of the lower grinding roller, and the cavity and slide rail limit the side grinding plate, so that while the lower grinding roller rotates and grinds, it can drive the side grinding plate to move synchronously for grinding, realizing multi-directional synchronous grinding of the semi-annular bearing and improving work efficiency.
[0020] 4. This invention, by setting up a drive motor, a rotating disk, a sliding guide rod, a connecting fixing plate, and an adjusting guide frame, allows the drive motor to drive the rotating disk to rotate. The rotation of the rotating disk causes the sliding guide rod to rotate eccentrically. While rotating, the sliding guide rod slides inside the adjusting guide frame, causing the adjusting guide frame to reciprocate left and right. The movement of the adjusting guide frame drives the mounting bracket to move synchronously through the connecting fixing plate. The movement of the mounting bracket drives the upper and lower grinding rollers to reciprocate synchronously. This allows the upper and lower grinding rollers to perform left and right grinding while rotating, ensuring that the contact trajectory between the upper and lower grinding rollers and the surface of the semi-annular bearing evenly covers the entire processing surface, avoiding over-grinding or under-grinding in local areas due to repeated grinding.
[0021] 5. This invention, by setting up a dust collection box, an air pump, a multi-port air supply pipe, a telescopic air supply pipe, a fixed support plate, a connecting air pipe, and a dust collection hood, allows the air pump to extract air from the surface of the processing frame using the multi-port pipe. This draws the debris generated during grinding into the dust collection box for unified collection, preventing the debris from scattering in the air and affecting the working environment. It also reduces debris residue on the surface of the semi-annular bearing, avoiding any impact on the grinding effect. The fixed support plate, in conjunction with the telescopic air supply pipe, allows the adjusting guide to move synchronously with the connecting air pipe during movement, enabling the connecting air pipe to perform comprehensive dust collection and increasing the dust collection range. The dust collection hood further expands the dust collection range and improves the dust collection effect. Attached Figure Description

[0024] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0025] Please see the appendix Figure 1 -Appendix Figure 3 This invention provides an internal combustion engine bearing processing equipment, including a processing frame 1, a drive adjustment mechanism 4 on the processing frame 1, a support frame 2 fixedly installed on the upper surface of the processing frame 1, and a drive cylinder 3 for adjusting the height of the drive adjustment mechanism 4 installed on the support frame 2. The drive adjustment mechanism 4 includes a support crossbeam 401 fixedly installed at the end of the output shaft of the drive cylinder 3. Multiple electric upper conveying rollers 402 are installed on the support crossbeam 401. An adjustment connecting frame 403 is fixedly installed on the surface of the processing frame 1. Multiple electric lower conveying rollers 404 are installed on the adjustment connecting frame 403. A semi-annular bearing 7 is placed between the upper conveying rollers 402 and the lower conveying rollers 404. By setting up a drive cylinder 3, a support crossbeam 401, an upper conveying roller 402, and a lower conveying roller 404, the semi-annular bearing 7 can be conveyed by the rotational cooperation of the upper and lower conveying rollers 402 and 404. This allows the semi-annular bearing 7 to rotate on its own, eliminating the need for repeated manual adjustments by the operator. This enables multi-directional grinding of the surface of the semi-annular bearing 7 and effectively avoids obstruction at the clamping point. The drive cylinder 3 moves the support crossbeam 401 up and down, adjusting the distance between the upper and lower conveying rollers 402 and 404 to meet the processing requirements of semi-annular bearings 7 of different thicknesses, thus improving the versatility of the equipment.
[0026] For further details, please refer to the appendix. Figure 3 -Appendix Figure 6 The processing frame 1 is equipped with a grinding mechanism 5 for grinding the semi-annular bearing shell 7. The grinding mechanism 5 includes two mounting brackets 501. An electric upper grinding roller 504 and an electric lower grinding roller 505 are provided between the two mounting brackets 501. The lower grinding roller 505 is installed between the two mounting brackets 501, and the upper grinding roller 504 is slidably mounted on the two mounting brackets 501. The processing frame 1 is equipped with a reciprocating motion mechanism for driving the two mounting brackets 501 to move back and forth.
[0027] By setting up an upper grinding roller 504 and a lower grinding roller 505, the surface of the semi-annular bearing 7 can be ground by the rotation of the upper grinding roller 504 and the lower grinding roller 505. The upper and lower surfaces of the semi-annular bearing 7 can be ground simultaneously. In conjunction with the upper conveying roller 402 and the lower conveying roller 404, continuous grinding can be achieved without repeatedly stopping the machine to adjust the position of the bearing, thus improving work efficiency.
[0028] For details, please refer to the appendix. Figure 3 and attached Figure 8 The reciprocating motion mechanism includes an adjusting guide frame 510. Both ends of the adjusting guide frame 510 are fixedly installed with connecting fixing plates 515. The two connecting fixing plates 515 are respectively fixedly installed on adjacent mounting brackets 501. The mounting brackets 501 are slidably arranged in a slide groove opened on the processing frame 1. The processing frame 1 is equipped with a drive motor 512. The output shaft of the drive motor 512 is fixedly installed with a rotating disk 511. A sliding guide rod 513 is eccentrically installed on the rotating disk 511. The sliding guide rod 513 is slidably arranged in the adjusting guide frame 510.
[0029] By setting up a drive motor 512, a rotating disk 511, a sliding guide rod 513, a connecting fixing plate 515, and an adjusting guide frame 510, the drive motor 512 drives the rotating disk 511 to rotate. The rotation of the rotating disk 511 drives the sliding guide rod 513 to rotate eccentrically. While rotating, the sliding guide rod 513 slides inside the adjusting guide frame 510, driving the adjusting guide frame 510 to reciprocate left and right. The movement of the adjusting guide frame 510 drives the mounting bracket 501 to move synchronously through the connecting fixing plate 515. The movement of the mounting bracket 501 drives the upper grinding roller 504 and the lower grinding roller 505 to reciprocate synchronously. This allows the upper grinding roller 504 and the lower grinding roller 505 to perform left and right grinding while rotating and grinding. This ensures that the contact trajectory between the roller body of the upper grinding roller 504 and the surface of the semi-annular bearing 7 evenly covers the entire processing surface, avoiding over-grinding or under-grinding in local areas due to repeated grinding.
[0030] For details, please refer to the appendix. Figure 8 and attached Figure 9 Both ends of the upper grinding roller 504 are equipped with adjusting sliders 503. The adjusting sliders 503 are slidably disposed inside the sliding groove opened on the mounting bracket 501. The mounting bracket 501 is threadedly installed with an adjusting threaded rod 502 at the position of the sliding groove. The top end of the adjusting threaded rod 502 is fixed with a rotating plate, and the bottom end of the adjusting threaded rod 502 is rotatably mounted on the adjusting slider 503. Several electric push rods 405 are fixedly installed on the surface of the processing frame 1. The output ends of the several electric push rods 405 are all fixedly connected to the adjusting connecting frame 403.
[0031] By setting up an adjusting slider 503, an adjusting threaded rod 502, and an electric push rod 405, the electric push rod 405 drives the adjusting connecting frame 403 to move up and down. The movement of the adjusting connecting frame 403 drives the lower grinding roller 505 to move up and down synchronously, thereby adjusting the position of the lower grinding roller 505. Rotating the adjusting threaded rod 502 drives the adjusting threaded rod 502 to rotate, which in turn causes the adjusting slider 503 to move up and down. Simultaneously, the movement of the adjusting slider 503 drives the upper grinding roller 504 to move synchronously, thereby adjusting the position of the upper grinding roller 504. This method can be used for semi-annular bearings 7 of different specifications and thicknesses, thus improving its applicability.
[0032] For details, please refer to the appendix. Figure 3 Appendix Figure 5 and attached Figure 6The outer surface of the lower grinding roller 505 is slidably fitted with several side grinding plates 506 that fit against the side of the semi-annular bearing 7. The lower grinding roller 505 has a cavity inside, and the grinding roller has multiple slides that communicate with the cavity. The side grinding plates 506 are slidably disposed in the cavity and slides. The top of the processing frame 1 is provided with a spacing adjustment frame 508 for adjusting the spacing between the multiple side grinding plates 506.
[0033] By setting a side grinding plate 506 and a spacing adjustment frame 508, the side grinding plate 506 can be used to grind the side of the semi-annular bearing 7. The side grinding plate 506 slides in the cavity inside the lower grinding roller 505. The cavity and slide rail limit the side grinding plate 506, so that while the lower grinding roller 505 rotates and grinds, it can drive the side grinding plate 506 to move synchronously and grind, realizing multi-directional synchronous grinding of the semi-annular bearing 7 and improving work efficiency.
[0034] For details, please refer to the appendix. Figure 3 and attached Figure 8 The spacing adjustment frame 508 has strip-shaped slides at positions directly opposite several side grinding plates 506. Several strip-shaped slides on both sides are arranged in an inverted V-shape. Sliding guide rods 513 are slidably installed inside the strip-shaped slides. Limiting anti-detachment plates 514 are fixedly installed at the bottom end of the sliding guide rods 513. Support brackets 507 are fixedly installed at the top end of the sliding guide rods 513. Side support plates are rotatably set in the corresponding support brackets 507. Multiple drive push rods 509 are fixedly installed on the processing frame 1. The spacing adjustment frame 508 is fixedly connected to the output end of the drive push rods 509.
[0035] By setting up a drive push rod 509, a sliding guide rod 513, a support bracket 507, and a limiting anti-detachment plate 514, the drive push rod 509 drives the spacing adjustment frame 508 to move. During the movement of the spacing adjustment frame 508, multiple strip slides drive multiple sliding guide rods 513 to move closer or further apart. The movement of the sliding guide rods 513 drives the side grinding plates 506 to move synchronously through the support bracket 507, thereby adjusting the position between the multiple side grinding plates 506. This allows for the grinding of semi-annular bearing shells 7 of different specifications, and also limits the semi-annular bearing shells 7 to prevent displacement between the multiple semi-annular bearing shells 7.
[0036] For details, please refer to the appendix. Figure 4 and attached Figure 7The processing frame 1 is equipped with a dust collection mechanism 6. The dust collection mechanism 6 includes a dust collection box 601 fixedly installed inside the processing frame. The dust collection box 601 is equipped with a cleaning door. The dust collection box 601 is fixedly installed with an air pump 602 and several multi-port air pipes 603. The air inlet pipe of the air pump 602 passes through the outside of the dust collection box 601 and extends into the inside of the dust collection box 601. The multi-port air pipes 603 are connected to each other and the bottom air inlet end passes through the outer wall of the dust collection box 601 and extends into the inside of the dust collection box 601.
[0037] By setting up a dust collection box 601, an air pump 602, and a multi-port air supply pipe 603, the air pump 602 can be turned on to extract air from the surface of the processing frame 1 through the multi-port pipe, drawing the debris generated during the grinding process into the dust collection box 601 for unified collection, preventing the debris from being scattered in the air and affecting the working environment. At the same time, it reduces the amount of debris residue on the surface of the semi-annular bearing 7, thus avoiding affecting the grinding effect.
[0038] For details, please refer to the appendix. Figure 7 The end of the multi-channel air supply pipe 603 is fixed with a telescopic air supply pipe 604, and the top of the telescopic air supply pipe 604 is fixedly installed with a connecting air pipe 605. The connecting air pipe 605 is fixedly connected to the adjusting guide frame 510 through a fixed support plate 608, and the top of the connecting air pipe 605 is installed with a guide dust collection hood 606.
[0039] By setting up a telescopic air supply pipe 604, a fixed support plate 608, a connecting air pipe 605, and a dust collection hood 606, the fixed support plate 608 enables the adjusting guide frame 510 to move synchronously with the telescopic air supply pipe 604 during its movement. This allows the connecting air pipe 605 to perform comprehensive dust collection, increasing the dust collection range. The dust collection hood 606 further expands the dust collection range and improves the dust collection effect.
[0040] For details, please refer to the appendix. Figure 7 The dust collection box 601 has a detachable and sliding dust collection rack 607 installed inside. The dust collection rack 607 is installed between the air inlet end of the air supply pipe and the air inlet pipe of the air pump 602.
[0041] By setting up a dust collection rack 607, the dust and debris drawn in can be isolated, making it easier to process later, while preventing them from entering the exhaust fan and causing damage to the exhaust fan.
[0042] Furthermore, both the upper conveyor roller 402 and the lower conveyor roller 404 are provided with anti-slip ribs on their outer surfaces. The anti-slip ribs are made of elastic and deformable material. By setting the elastic anti-slip ribs, the stability of the upper conveyor roller 402 and the lower conveyor roller 404 in relation to the semi-annular bearing 7 can be increased. At the same time, it can avoid damage to the surface of the semi-annular bearing 7 caused by rigid force. It can also better adapt when encountering uneven protrusions.
[0043] Working principle: The semi-annular bearing 7 is placed above the lower conveying roller 404. Then, the drive cylinder 3 is opened by controlling the drive cylinder 3 to drive the support crossbeam 401 to move downward. The downward movement of the support crossbeam 401 drives the upper conveying roller 402 to move upward synchronously, so that the upper conveying roller 402 can fit into the surface of the semi-annular bearing 7. The upper conveying roller 402 and the lower conveying roller 404 are controlled to start rotating, so as to realize the conveying work of the semi-annular bearing 7. The electric push rod 405 is activated, which drives the adjusting connecting frame 403 to move upward. The movement of the adjusting connecting frame 403 drives the lower grinding roller 505 to move upward synchronously, so that the lower grinding roller 505 is in contact with the bottom of the semi-annular bearing 7. The adjusting threaded rod 502 is rotated, which drives the adjusting threaded rod 502 to rotate. The rotation of the adjusting threaded rod 502 causes the adjusting slider 503 to move downward. At the same time, the movement of the adjusting slider 503 can drive the upper grinding roller 504 to move synchronously, so that the upper grinding roller 504 is in contact with the surface of the semi-annular bearing 7. The control starts the drive push rod 509, which drives the spacing adjustment frame 508 to move. During the movement of the spacing adjustment frame 508, multiple strip slides drive multiple sliding guide rods 513 to move closer or further apart. The movement of the sliding guide rods 513 drives the side grinding plates 506 to move synchronously through the support bracket 507, thereby adjusting the position between the multiple side grinding plates 506. The multiple grinding rollers are adjusted according to the size of the semi-annular bearing 7, so that the side grinding plates 506 are adjusted to fit against the side of the semi-annular bearing 7. Then, control the operation of the upper grinding roller 504 and the lower grinding roller 505 to achieve the grinding work of the semi-annular bearing 7. While the lower grinding roller 505 rotates and grinds, it can drive the side grinding plate 506 to move synchronously to grind, so as to achieve multi-directional synchronous grinding of the semi-annular bearing 7. When the air pump 602 is turned on, it can perform air extraction on the surface of the processing frame 1 using a multi-port pipe, drawing the debris generated during the grinding process into the dust collection box 601. The dust collection rack 607 collects the debris uniformly. The fixed support plate 608 allows the adjusting guide 510 to move synchronously with the telescopic air supply pipe 604 during its movement, enabling the connecting air pipe 605 to perform comprehensive dust extraction.
[0044] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
