Description

Technical Field

[0001] The present invention relates to a structure and method for loading and unloading bearing bushes, belonging to the technical field of bearing bush processing. Background Art

[0002] A bearing bush is the part that contacts the journal of a sliding bearing, with a shape of a semi-cylindrical surface in the shape of a tile, generally made of wear-resistant materials such as bronze and antifriction alloy. A very thin oil film is required between the bearing bush and the rotating shaft to play a lubricating role. If the lubrication is poor, there will be direct friction between the bearing bush and the rotating shaft, and the friction will generate a very high temperature.

[0003] At the present stage, in order to make the bearing bush and the rotating shaft have a good lubrication effect, grooved oil lines need to be processed on the bearing bush. The oil line processing generally presses the half bearing bush into a semi-circular tire and processes it by milling. Although the processing quality is high and it is easy to realize automated production line production, burrs will be generated on the tile mouth plane in the tool exit direction of the bearing bush, the tool wear is also large, and the processing cost is high.

[0004] Turning the two bearing bushes into a cylindrical shape for machining can avoid the generation of burrs on the tile mouth plane in the tool exit direction of the bearing bush. How to realize the loading and unloading of the two half bearing bushes in a predetermined docking manner during the automated production line process has important research significance.

[0044] See Figure 1 and Figure 2 , an upper and lower material structure for a bearing shell according to an embodiment of the present invention includes a semi-bearing shell circular splicing assembly 1, a circular spliced semi-bearing shell transfer assembly 2, a circular spliced semi-bearing shell working position switching assembly 3, and a circular spliced semi-bearing shell processing and offline assembly 4;

[0045] Among them, the semi-bearing shell circular splicing assembly 1 docks the semi-bearing shells to be processed into a cylindrical shape and transports them to the loading position;

[0046] Among them, the circular spliced semi-bearing shell transfer assembly 2 transfers the semi-bearing shells docked into a cylindrical shape at the loading position to the circular spliced semi-bearing shell working position switching assembly 3;

[0047] Among them, the circular spliced semi-bearing shell working position switching assembly 3 transfers the unprocessed semi-bearing shells docked into a cylindrical shape to the processing position, and at the same time, the circular spliced semi-bearing shell working position switching assembly 3 transfers the processed semi-bearing shells docked into a cylindrical shape to the unloading position;

[0048] Among them, the circular spliced semi-bearing shell processing and offline assembly 4 outputs the processed semi-bearing shells docked into a cylindrical shape at the unloading position.

[0049] In this embodiment, the semi-bearing shell circular splicing assembly 1, the circular spliced semi-bearing shell transfer assembly 2, and the circular spliced semi-bearing shell processing and offline assembly 4 are commonly connected to an n-shaped base 5; the semi-bearing shell circular splicing assembly 1 is at one end of the base 5, the circular spliced semi-bearing shell processing and offline assembly 4 is at the other end of the base 5, and the circular spliced semi-bearing shell transfer assembly 2 is between the semi-bearing shell circular splicing assembly 1 and the circular spliced semi-bearing shell processing and offline assembly 4; a bottom plate 6 is further connected to the bottom of the base 5, the circular spliced semi-bearing shell working position switching assembly 3 is arranged on the bottom plate 6, and the circular spliced semi-bearing shell working position switching assembly 3 and the circular spliced semi-bearing shell transfer assembly 2 form an operation docking relationship.

[0050] Specifically, the n-shaped base 5 plays a supporting role for the semi-bearing shell circular splicing assembly 1, the circular spliced semi-bearing shell transfer assembly 2, and the circular spliced semi-bearing shell processing and offline assembly 4. At the same time, the bottom plate 6 plays an installation and supporting role for the n-shaped base 5 and the circular spliced semi-bearing shell working position switching assembly 3, so that the semi-bearing shell circular splicing assembly 1, the circular spliced semi-bearing shell transfer assembly 2, the circular spliced semi-bearing shell working position switching assembly 3, and the circular spliced semi-bearing shell processing and offline assembly 4 form a continuous operation docking relationship. That is, the semi-bearing shell circular splicing assembly 1 docks the semi-bearing shells to be processed into a cylindrical shape and transports them to the loading position, the circular spliced semi-bearing shell transfer assembly 2 transfers the semi-bearing shells docked into a cylindrical shape at the loading position to the circular spliced semi-bearing shell working position switching assembly 3, the circular spliced semi-bearing shell working position switching assembly 3 transfers the unprocessed semi-bearing shells docked into a cylindrical shape to the processing position, and at the same time, the circular spliced semi-bearing shell working position switching assembly 3 transfers the processed semi-bearing shells docked into a cylindrical shape to the unloading position; the circular spliced semi-bearing shell processing and offline assembly 4 outputs the processed semi-bearing shells docked into a cylindrical shape at the unloading position.

[0051] See Figure 3 and Figure 4 In this embodiment, the split bearing shell circular assembly 1 includes a split bearing shell slideway 7, a slideway adapter plate 8, a loading slideway 9, a bearing shell stop arm 10, a bearing shell fork 11 and a pusher claw 12; one end of the split bearing shell slideway 7 is connected to one end of the loading slideway 9 through the slideway adapter plate 8, the other end of the split bearing shell slideway 7 faces upward above the loading slideway 9, and a pusher avoidance gap 13 is formed between the loading slideway 9 and the split bearing shell slideway 7; the bearing shell stop arm 10 is connected to the middle position of the split bearing shell slideway 7, the bearing shell fork 11 is located upstream of the bearing shell stop arm 10, and a swing shaft 14 is connected between the bearing shell fork 11 and the split bearing shell slideway 7; the pusher claw 12 is located at the upper part of the loading slideway 9, and the pusher claw 12 moves along the loading slideway 9 and passes through the pusher avoidance gap 13 to push the bearing shell on the loading slideway 9. A fork driving cylinder 15 is connected to the bottom of the split bearing shell slideway 7, and the fork driving cylinder 15 is connected to the swing shaft 14; a claw adapter plate 16 is connected to the side of the pusher claw 12, and the claw adapter plate 16 is connected to a claw driving cylinder 17.

[0052] Specifically, split bearing shells to be spliced into a cylindrical shape are arranged on the split bearing shell slideway 7, and the openings of the split bearing shells face the bearing shell stop arm 10, so as to prevent the split bearing shells from being back-to-back and make the split bearing shells form a circle with their mouths facing each other. Among them, the bearing shell fork 11 turns to one side of the bearing shell stop arm 10 to form a block, so that the split bearing shell slides from the other side of the bearing shell stop arm 10 to the loading slideway 9. Immediately afterwards, the bearing shell fork 11 turns to the other side of the bearing shell stop arm 10 to form a block, so that the next split bearing shell slides from the side of the bearing shell stop arm 10 that is released from the block to the loading slideway 9, and the split bearing shells that slide to the two loading slideways 9 form a circle with their mouths facing each other.

[0053] Among them, the commutation of the bearing shell fork 11 is realized by the fork driving cylinder 15 driving the swing shaft 14. For the split bearing shells that slide to the loading slideway 9 to form a circle, the claw driving cylinder 17 drives the pusher claw 12 through the claw adapter plate 16, and the pusher claw 12 moves along the loading slideway 9 to push the split bearing shells that form a circle to the loading position.

[0054] Among them, the design of the pusher avoidance gap 13 avoids the interference of the split bearing shell slideway 7 when the pusher claw 12 moves along the loading slideway 9, and the support of the split bearing shell slideway 7 is realized through the slideway adapter plate 8.

[0055] In this embodiment, the circular-joining half-shaft bearing transfer assembly 2 includes a swing arm body 18, a swing arm drive shaft 19, and a swing arm drive cylinder 20. The swing arm body 18 includes a first transfer portion 21, a second transfer portion 22, and a swing arm drive portion 23. The first transfer portion 21, the second transfer portion 22, and the drive portion are in an L shape. The first transfer portion 21 is connected to a first bearing suction cylinder 24, and the first bearing suction cylinder 24 is connected to a first bearing positioning disk 25. The second transfer portion 22 is connected to a second bearing suction cylinder 26, and the second bearing suction cylinder 26 is connected to a second bearing positioning disk 27. The swing arm drive shaft 19 is connected to the swing arm drive portion 23, and the swing arm drive cylinder 20 is fixed to the swing arm drive shaft 19.

[0056] Specifically, the L-shaped swing arm body 18 formed by the first transfer portion 21, the second transfer portion 22, and the swing arm drive portion 23 realizes the continuity of loading and unloading. That is, when the first transfer portion 21 adsorbs the half-shaft bearings joined into a circle from the loading position, the second transfer portion 22 adsorbs the processed half-shaft bearings on the circular-joining half-shaft bearing station switching assembly 3 at this time. The swing arm drive cylinder 20 drives the swing arm body 18 to rotate through the swing arm drive shaft 19. Due to the L-shaped design, when the second transfer portion 22 adsorbs the processed bearings and moves to the circular-joining half-shaft bearing processing offline assembly 4, the circular-joining half-shaft bearing station switching assembly 3 is vacated at this time, and the first transfer portion 21 just carries the unprocessed bearings to the corresponding station of the just-vacated circular-joining half-shaft bearing station switching assembly 3, and the whole process is more closely connected.

[0057] Among them, the first transfer portion 21 uses the first bearing positioning disk 25 to adsorb the half-shaft bearings joined into a circle through the first bearing suction cylinder 24. The first bearing positioning disk 25 has adsorption holes and sucks the cross-section of the half-shaft bearings using the vacuum adsorption principle. Similarly, the second transfer portion 22 uses the second bearing positioning disk 27 to adsorb the half-shaft bearings joined into a circle through the second bearing suction cylinder 26.

[0058] See Figure 5 In this embodiment, the circular-joining half-shaft bearing station switching assembly 3 includes a station switching beam 28, a first station turntable 29, a second station turntable 30, a switching beam drive shaft 31, and a switching beam drive cylinder 32. The first station turntable 29 is connected to one end of the station switching beam 28, and the second station turntable 30 is connected to the other end of the station switching beam 28. The switching beam drive shaft 31 is connected to the station switching beam 28, and the switching beam drive cylinder 32 is connected to the switching beam drive shaft 31. The first bearing positioning fixture 33 is provided inside the first station turntable 29, and the second bearing positioning fixture 34 is provided inside the second station turntable 30. Clamping adjustment gaps 35 are formed in both the first bearing positioning fixture 33 and the second bearing positioning fixture 34, and shelving flanges 36 are formed at the upper ends of the first bearing positioning fixture 33 and the second bearing positioning fixture 34.

[0059] Specifically, the switching beam driving cylinder 32 drives the workstation switching beam 28 to rotate through the switching beam driving shaft 31. The rotation of the workstation switching beam 28 drives the first workstation turntable 29 and the second workstation turntable 30 at both ends to switch the workstations. When the first workstation turntable 29 is in the processing workstation, the second workstation turntable 30 is in the unloading workstation. The second workstation turntable 30 at the unloading workstation receives the unprocessed half-bearing shell after unloading. When the workstation switching beam 28 rotates and drives the first workstation turntable 29 and the second workstation turntable 30 to rotate again, the unprocessed half-bearing shell received by the second workstation turntable 30 after unloading is transferred to the processing workstation. At the same time, the processed half-bearing shell on the first workstation turntable 29 is transferred to the unloading workstation at the same time. The process is repeated to realize the continuous flow operation of loading, processing and unloading.

[0060] Among them, the first station turntable 29 supports the received half-bearing that is butt-jointed into a circle through the first bearing positioning fixture 33, and the second station turntable 30 supports the received half-bearing that is butt-jointed into a circle through the second bearing positioning fixture 34. The first bearing positioning fixture 33 is placed on the first station turntable 29 through the rest flange 36, and the second bearing positioning fixture 34 is placed on the second station turntable 30 through the rest flange 36. The design of the clamping adjustment gap 35 enables the first bearing positioning fixture 33 and the second bearing positioning fixture 34 to fine-tune the size of the bearing.

[0061] See also Figure 6 In this embodiment, the rounded half bearing processing line assembly 4 includes a feed chute support arm 37 and a feed chute body 38; the feed chute support arm 37 is connected to the side of the base 5, and the lower end of the feed chute body 38 is connected to the feed chute support arm 37 through a feed chute support column. The upper part of the feed chute support arm 37 is connected to a correction drive motor 39, and the correction drive motor 39 is connected to a bearing correction block 40, and the bearing correction block 40 is located above the feed chute body 38.

[0062] Specifically, the unloading chute body 38 is installed on the base 5 through the unloading chute support arm 37, and the rounded half-bearing shell processing offline assembly 4 receives the processed half-bearing shell transferred from the rounded half-bearing shell transfer assembly 2 through the unloading chute body 38, and the half-bearing shells are output in sequence on the unloading chute body 38. Since the postures of the half-bearing shells on the unloading chute body 38 are different, and the docking into a circle state has been released, in order to make the posture of the half-bearing shell open to the upper back to fit the unloading chute body 38, the bearing alignment block 40 is driven to rotate by the alignment drive motor 39. When the posture of the half-bearing shell is tilted or the opening is facing downward, the bearing alignment block 40 can align the half-bearing shell whose posture does not meet the requirements.

[0063] The present invention also provides a bearing loading and unloading method, which adopts the bearing loading and unloading structure of the above embodiment, and comprises the following steps:

[0064] S1. Butt the half shaft tiles to be processed into a cylindrical shape and convey them to the loading position;

[0065] S2. Transfer the unprocessed half shaft tiles butt-jointed into a cylindrical shape to the processing position, and at the same time transfer the processed half shaft tiles butt-jointed into a cylindrical shape to the unloading position;

[0066] S3. Output the processed half shaft tiles butt-jointed into a cylindrical shape at the unloading position.

[0067] In summary, the present invention is provided with a split bearing shell circular splicing assembly 1, a circular splicing bearing shell transfer assembly 2, a circular splicing bearing shell station switching assembly 3, and a circular splicing bearing shell processing and offline assembly 4. The split bearing shell circular splicing assembly 1 docks the bearing shells to be processed into a cylindrical shape and conveys them to the loading position. The circular splicing bearing shell transfer assembly 2 transfers the bearing shells docked into a cylindrical shape at the loading position to the circular splicing bearing shell station switching assembly 3. The circular splicing bearing shell station switching assembly 3 transfers the unprocessed bearing shells docked into a cylindrical shape to the processing position, and at the same time, the circular splicing bearing shell station switching assembly 3 transfers the processed bearing shells docked into a cylindrical shape to the unloading position. The circular splicing bearing shell processing and offline assembly 4 outputs the processed bearing shells docked into a cylindrical shape at the unloading position. The n-shaped base 5 serves as a support for the split bearing shell circular splicing assembly 1, the circular splicing bearing shell transfer assembly 2, and the circular splicing bearing shell processing and offline assembly 4. At the same time, the bottom plate 6 serves as an installation support for the n-shaped base 5 and the circular splicing bearing shell station switching assembly 3, thereby enabling the split bearing shell circular splicing assembly 1, the circular splicing bearing shell transfer assembly 2, the circular splicing bearing shell station switching assembly 3, and the circular splicing bearing shell processing and offline assembly 4 to form a continuous docking relationship for operation. That is, the split bearing shell circular splicing assembly 1 docks the bearing shells to be processed into a cylindrical shape and conveys them to the loading position. The circular splicing bearing shell transfer assembly 2 transfers the bearing shells docked into a cylindrical shape at the loading position to the circular splicing bearing shell station switching assembly 3. The circular splicing bearing shell station switching assembly 3 transfers the unprocessed bearing shells docked into a cylindrical shape to the processing position, and at the same time, the circular splicing bearing shell station switching assembly 3 transfers the processed bearing shells docked into a cylindrical shape to the unloading position. The circular splicing bearing shell processing and offline assembly 4 outputs the processed bearing shells docked into a cylindrical shape at the unloading position. The split bearing shells are arranged on the split bearing shell slideway 7, and the openings of the bearing shells face the bearing shell stop arm 10, thereby preventing the bearing shells from being back-to-back and enabling the bearing shell openings to be mouth-to-mouth to form a circle. Among them, the bearing fork 11 turns to one side of the bearing shell stop arm 10 to form a block, so that the bearing shell slides from the other side of the bearing shell stop arm 10 onto the loading slideway 9. Immediately afterwards, the bearing fork 11 turns to the other side of the bearing shell stop arm 10 to form a block, so that the next bearing shell slides from the side of the bearing shell stop arm 10 where the block is released onto the loading slideway 9. The bearing shells sliding onto the two loading slideways 9 are mouth-to-mouth spliced into a circle. The commutation of the bearing fork 11 is achieved by driving the swing shaft 14 through the fork driving cylinder 15. For the bearing shells spliced into a circle and sliding onto the loading slideway 9, the claw driving cylinder 17 drives the pusher claw 12 through the claw adapter plate 16, and the pusher claw 12 moves along the loading slideway 9 to push the bearing shells spliced into a circle to the loading position. The design of the pusher avoidance gap 13 avoids the interference of the split bearing shell slideway 7 when the pusher claw 12 moves along the loading slideway 9, and the support of the split bearing shell slideway 7 is realized through the slideway adapter plate 8.The L-shaped swing arm body 18 formed by the first transfer part 21, the second transfer part 22 and the driving part realizes the continuity of loading and unloading. That is, when the first transfer part 21 adsorbs the half axle tiles spliced into a circle at the loading position, the second transfer part 22 adsorbs the processed half axle tiles on the half axle tile assembling station switching component 3 at this time. The swing arm driving cylinder 20 drives the swing arm body 18 to rotate through the swing arm driving shaft 19. Due to the L-shaped design, when the second transfer part 22 adsorbs the processed axle tile and moves it to the half axle tile assembling and processing offline component 4, the half axle tile assembling station switching component 3 is vacated at this time, and the first transfer part 21 just carries the unprocessed axle tile and transfers it to the corresponding station of the just-vacated half axle tile assembling station switching component 3. The whole process is more closely connected. The first transfer part 21 uses the first axle tile suction cylinder 24 to adsorb the half axle tiles docked into a circle by using the first axle tile positioning plate 25. The first axle tile positioning plate 25 has adsorption holes and sucks the cross section of the half axle tile by using the principle of vacuum adsorption. Similarly, the second transfer part 22 uses the second axle tile suction cylinder 26 to adsorb the half axle tiles docked into a circle by using the second axle tile positioning plate 27. The switching beam driving cylinder 32 drives the station switching beam 28 to rotate through the switching beam driving shaft 31. The rotation of the station switching beam 28 drives the first station turntable 29 and the second station turntable 30 at both ends to perform station switching. When the first station turntable 29 is at the processing station, the second station turntable 30 is at the unloading station. After the second station turntable 30 at the unloading station unloads the material, it receives the unprocessed half axle tiles at the same time. When the station switching beam 28 rotates to drive the first station turntable 29 and the second station turntable 30 to rotate again, the unprocessed half axle tiles received after the second station turntable 30 unloads the material are transferred to the processing station. At the same time, the processed half axle tiles on the first station turntable 29 are transferred to the unloading station at the same time. Repeating this process realizes the continuous flow operation of loading, processing and unloading. The first station turntable 29 uses the first axle tile positioning fixture 33 to carry the half axle tiles docked into a circle received. The second station turntable 30 uses the second axle tile positioning fixture 34 to carry the half axle tiles docked into a circle received. The first axle tile positioning fixtures 33 are all placed on the first station turntable 29 through the shelving flange 36, and the second axle tile positioning fixtures 34 are all placed on the second station turntable 30 through the shelving flange 36. The design of the clamping adjustment gap 35 enables the first axle tile positioning fixture 33 and the second axle tile positioning fixture 34 to finely adjust the size of the axle tile carried. The blanking chute body 38 is installed on the base 5 through the blanking chute support arm 37. The half axle tile assembling and processing offline component 4 receives the processed half axle tiles transferred by the half axle tile transfer component 2 through the blanking chute body 38, and the half axle tiles are output in sequence on the blanking chute body 38.Since the attitude of the half-axis bearing shell is different on the blanking chute body 38 and the butt-jointed and circular state has been released, in order to make the attitude of the half-axis bearing shell with the opening facing upward and the back fitting the blanking chute body 38, the shaft bearing shell aligning driving motor 39 drives the bearing shell aligning block 40 to rotate. When the attitude of the half-axis bearing shell is inclined or the opening faces downward, the bearing shell aligning block 40 can align the half-axis bearing shell with an unsatisfactory attitude. The present invention can realize the butt-joint of the semi-circular half-axis bearing shell into a cylindrical shape for loading and unloading processing, avoid burrs generated in the cutting direction during the individual processing of the half-axis bearing shell, improve the processing quality of the oil line, and reduce the processing cost.
