A half-axle tile butt joint vehicle oil line system and process

Abstract

A half-axle tile docking vehicle oil line system and process. The half-axle tiles to be processed are docked into a cylindrical shape by a half-axle tile circular splicing component and conveyed to the feeding position. A linear driving member drives the feed lever movable seat to move up and down, and the up and down movement of the feed lever movable seat drives the transmission sleeve adapter seat to move up and down. The up and down movement of the transmission sleeve adapter seat is converted into the self-rotation movement of the tool bar shaft body through the tool bar shaft cam sleeve and the transmission sleeve roller shaft. The self-rotation movement of the tool bar shaft body enables the carried axle tile processing cutter head to perform the feed and retraction actions for axle tile oil line processing. The rotation of the main shaft body is controlled to drive the axle tile processing cutter head carried by the tool bar shaft body to rotate, so as to perform oil line processing on the half-axle tiles docked into a cylindrical shape in the upper positioning cone plate. It is output through the circular splicing half-axle tile processing offline component. The present invention realizes the feeding and discharging of two half-axle tiles in a predetermined circular docking manner, is not easy to generate burrs, and has high oil line processing accuracy.

Description

Technical Field

[0001] The present invention relates to a half axle bearing bush butt-joint vehicle oil line system and process, 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, and is 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. At present, 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.

[0003] For oil line processing, generally, the half axle bearing bush is pressed into a semi-circular tire and processed by milling. Although the processing quality is high and it is easy to realize automated assembly 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. Turning the two bearing bushes into a cylindrical shape for machining can avoid generating burrs on the tile mouth plane in the tool exit direction of the bearing bush, but currently, there is a lack of a feasible technical solution for automatically butting the half axle bearing bushes into a circle, making it difficult to apply in the automated assembly line production process.

[0004] In the traditional oil line processing process, the bearing bush needs to be fixed, and a tool is used to process the inner side of the bearing bush. A tool is installed at the front end of the rotating shaft of the motor, and the bearing bush is placed in the accommodating space. When the motor starts, the rotating shaft drives the tool to rotate to process the inner side of the bearing bush. While the tool rotates around the rotating shaft, the rotating shaft moves along the axis direction of the bearing bush to realize the processing of the entire inner side of the bearing bush.

[0005] In the traditional processing method, the rotating shaft itself not only has a rotating motion but also a moving motion along the axis direction of the bearing bush. The feed amplitude and moving trajectory of the tool are controlled by the rotation and movement of the rotating shaft, making it difficult to accurately control the processing dimensions.

[0085] Specifically, half-axle bearings to be spliced into a cylindrical shape are arranged on the split-bearing slideway 63, and the openings of the half-axle bearings face the bearing retaining arm 66, so as to prevent the half-axle bearings from being back-to-back and make the half-axle bearings form a circle with their mouths facing each other. Among them, the bearing fork 67 turns to one side of the bearing retaining arm 66 to form a block, so that the half-axle bearing slides from the other side of the bearing retaining arm 66 to the loading slideway 65. Immediately afterwards, the bearing fork 67 turns to the other side of the bearing retaining arm 66 to form a block, so that the next half-axle bearing slides from the side of the bearing retaining arm 66 that is released from the block to the loading slideway 65, and the half-axle bearings sliding towards the two loading slideways 65 form a circle with their mouths facing each other.

[0086] Among them, the commutation of the bearing fork 67 is realized by the fork driving cylinder 71 driving the swing shaft 70. For the half-axle bearings that slide onto the loading slideway 65 to form a circle, the claw driving cylinder drives the pusher claw 68 through the claw adapter plate 72, and the pusher claw 68 moves along the loading slideway 65 to push the half-axle bearings that form a circle to the loading position.

[0087] Among them, the design of the pusher avoidance gap 69 avoids the interference of the split-bearing slideway 63 when the pusher claw 68 moves along the loading slideway 65, and the support of the split-bearing slideway 63 is realized through the slideway adapter plate 64.

[0088] Auxiliary Figure 6 and Figure 9, in this embodiment, the circular - assembled half - shaft bearing transfer component 2 includes a swing arm body 21, a swing arm drive shaft 22, and a swing arm drive cylinder 23; the swing arm body 21 includes a first transfer part 24, a second transfer part 25, and a swing arm drive part 26, and the first transfer part 24, the second transfer part 25, and the swing arm drive part 26 are in an L - shape; the first transfer part 24 is connected to a first bearing suction cylinder 27, and the first bearing suction cylinder 27 is connected to a first bearing positioning disk 28; the second transfer part 25 is connected to a second bearing suction cylinder 29, and the second bearing suction cylinder 29 is connected to a second bearing positioning disk 30; the swing arm drive shaft 22 is connected to the swing arm drive part 26, and the swing arm drive cylinder 23 is fixed to the connecting swing arm drive shaft 22.

[0089] Specifically, the L - shaped swing arm body 21 formed by the first transfer part 24, the second transfer part 25, and the swing arm drive part 26 realizes the continuity of loading and unloading. That is, when the first transfer part 24 adsorbs the circular - assembled half - shaft bearing from the loading position of the half - shaft bearing circular - assembling component 61, the second transfer part 25 adsorbs the processed half - shaft bearing on the circular - assembled half - shaft bearing station - switching component 3 at this time. The swing arm drive cylinder 23 drives the swing arm body 21 to rotate through the swing arm drive shaft 22. Due to the L - shaped design, when the second transfer part 25 adsorbs the processed bearing and moves to the unloading position, the circular - assembled half - shaft bearing station - switching component 3 becomes vacant at this time, and the first transfer part 24 just carries the unprocessed bearing and transfers it to the corresponding station of the just - vacated circular - assembled half - shaft bearing station - switching component 3. The whole process is more closely connected.

[0090] Among them, the first transfer part 24 uses the first bearing suction cylinder 27 to adsorb and dock the circular - assembled half - shaft bearing by the first bearing positioning disk 28. The first bearing positioning disk 28 has adsorption holes and sucks the cross - section of the half - shaft bearing by the principle of vacuum adsorption. Similarly, the second transfer part 25 uses the second bearing suction cylinder 29 to adsorb the circular - assembled half - shaft bearing by the second bearing positioning disk 30.

[0091] Auxiliary Figure 7 And Figure 9 , in this embodiment, the circular - assembled half - shaft bearing station - switching component 3 includes a station - switching beam 31, a first station turntable 32, a second station turntable 33, a switching beam drive shaft 34, and a switching beam drive cylinder 35; the first station turntable 32 is connected to one end of the station - switching beam 31, and the second station turntable 33 is connected to the other end of the station - switching beam 31; the switching beam drive shaft 34 is connected to the station - switching beam 31, and the switching beam drive cylinder 35 is connected to the switching beam drive shaft 34; a first bearing positioning fixture 36 is provided inside the first station turntable 32, and a second bearing positioning fixture 37 is provided inside the second station turntable 33; both the first bearing positioning fixture 36 and the second bearing positioning fixture 37 are formed with a clamping adjustment gap 38, and a placing flange 39 is formed at the upper ends of both the first bearing positioning fixture 36 and the second bearing positioning fixture 37.

[0092] Specifically, the switching beam driving cylinder 35 drives the station switching beam 31 to rotate through the switching beam driving shaft 34. The rotation of the station switching beam 31 drives the first station turntable 32 and the second station turntable 33 at both ends to perform station switching. When the first station turntable 32 is at the processing station, the second station turntable 33 is at the unloading station. After the second station turntable 33 at the unloading station unloads, it simultaneously receives the unprocessed half bearing shells. When the station switching beam 31 rotates to drive the first station turntable 32 and the second station turntable 33 to rotate again, the unprocessed half bearing shells received by the second station turntable 33 after unloading are transferred to the processing station. At the same time, the processed half bearing shells on the first station turntable 32 are transferred to the unloading station. By repeating this process, continuous flow operation of feeding, processing, and unloading is achieved.

[0093] Among them, the first station turntable 32 carries the butted and rounded half bearing shells received through the first bearing shell positioning fixture 36, and the second station turntable 33 carries the butted and rounded half bearing shells received through the second bearing shell positioning fixture 37. The first bearing shell positioning fixtures 36 are all placed on the first station turntable 32 through the shelving flanges 39, and the second bearing shell positioning fixtures 37 are all placed on the second station turntable 33 through the shelving flanges 39. The design of the clamping adjustment gap 38 enables the first bearing shell positioning fixture 36 and the second bearing shell positioning fixture 37 to finely adjust the size of the bearing shells carried.

[0094] Auxiliary Figure 8 And Figure 9 In this embodiment, the half bearing shell rounding assembly 61, the rounded half bearing shell transfer assembly 2, and the rounded half bearing shell processing and offline assembly 62 are jointly connected to an n-shaped base 73. Among them, the rounded half bearing shell processing and offline assembly 62 includes a blanking chute support arm 74 and a blanking chute body 75; the blanking chute support arm 74 is connected to the side of the base 73, and the lower end of the blanking chute body 75 is connected to the blanking chute support arm 74 through a blanking chute support column; a correcting drive motor 76 is connected to the upper part of the blanking chute support arm 74, the correcting drive motor 76 is connected to a bearing shell correcting block 77, and the bearing shell correcting block 77 is located above the blanking chute body 75.

[0095] Specifically, the blanking chute body 75 is installed on the base 73 through the blanking chute support arm 74. The rounded half bearing shell processing and offline assembly 62 receives the processed half bearing shells transferred by the rounded half bearing shell transfer assembly 2 through the blanking chute body 75, and the half bearing shells are output in sequence on the blanking chute body 75. Since the postures of the half bearing shells on the blanking chute body 75 are different and the butted and rounded state has been released, in order to make the posture of the half bearing shell with the opening facing up and the back fitting the blanking chute body 75, the correcting drive motor 76 drives the bearing shell correcting block 77 to rotate. When the posture of the half bearing shell is inclined or the opening faces down, the bearing shell correcting block 77 can correct the half bearing shells with unqualified postures.

[0096] Auxiliary Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, the feed lever movable seat 5, the feed lever body 6, the feed lever fixed seat 7, and the transmission sleeve adapter seat 8 form a lever structure. The connection position between the feed lever fixed seat 7 and the feed lever body 6 forms a fulcrum. The linear drive member 4 can adopt a double-headed oil cylinder. When the linear drive member 4 drives the feed lever movable seat 5 upward, the central position of the feed lever body 6 moves upward, and then the transmission sleeve adapter seat 8 moves upward; when the linear drive member 4 drives the feed lever movable seat 5 downward, the central position of the feed lever body 6 moves downward, and then the transmission sleeve adapter seat 8 moves downward. The lever design makes it easier to drive the transmission sleeve adapter seat 8. The transmission sleeve adapter seat 8 drives the upper transmission sleeve body 9 to move up and down. During the up and down movement of the upper transmission sleeve body 9, since the transmission sleeve roller 14 and the tool bar shaft cam sleeve 11 are in contact through the spiral track groove 16, the tool bar shaft cam sleeve 11 can be rotated. The rotation of the tool bar shaft cam sleeve 11 drives the connected tool bar shaft body 12 to rotate, and the rotation of the tool bar shaft body 12 drives the connected bearing shell processing tool disk 20 to rotate. Since the tool bar shaft body 12 is eccentrically designed relative to the main shaft body 13, the rotation of the tool bar shaft body 12 driving the bearing shell processing tool disk 20 can realize the feed and retraction actions.

[0097] Among them, feeding refers to the rotation of the bearing shell processing tool disk 20 to offset and contact the inner wall of the bearing shell where the oil line is processed, and retraction refers to the rotation of the bearing shell processing tool disk 20 to offset and disengage from the inner wall of the bearing shell where the oil line is processed. That is, through the eccentric design, the rotation of the tool bar shaft body 12 driving the bearing shell processing tool disk 20 will have a radial offset, and the feed and retraction are realized through this offset.

[0098] Among them, after feeding, the bearing shell processing tool disk 20 will rotate integrally under the drive of the main shaft body 13. Since the bearing shell processing tool disk 20 contacts the inner wall of the bearing shell, the processing of the bearing shell oil line is realized. The processing depth of the oil line is controlled by controlling the feed amount, and the processing width of the oil line is controlled by controlling the up and down movement amount of the bearing shell processing tool disk 20.

[0099] Auxiliary Figure 1 、 Figure 2 、 Figure 3 and Figure 4, in this embodiment, a first slider 40 is connected to one end of the feed lever body 6. The feed lever movable seat 5 is formed with a first through groove 41. The first slider 40 is located inside the first through groove 41, and the first slider 40 and the feed lever movable seat 5 are hinged by a first pin shaft; a second slider 42 is connected to the other end of the feed lever body 6. The feed lever fixed seat 7 is formed with a second through groove 43. The second slider 42 is located inside the second through groove 43, and the second slider 42 and the feed lever fixed seat 7 are hinged by a second pin shaft; a support flange 44 is formed in the middle of the feed lever body 6. The transmission sleeve adapter seat 8 is formed with a third through groove 45. The support flange 44 is located inside the third through groove 45, and the support flange 44 and the transmission sleeve adapter seat 8 are hinged by a third pin shaft.

[0100] Specifically, relative rotation cannot occur between the first slider 40 and the first through groove 41. It is preferably designed that the first slider 40 and the first through groove 41 are square. The first pin shaft can realize the rotation movement between the feed lever movable seat 5 and the feed lever body 6, which is convenient for up and down driving. Similarly, relative rotation cannot occur between the second slider 42 and the second through groove 43. It is preferably designed that the second slider 42 and the second through groove 43 are square. Since the feed lever fixed seat 7 cannot move up and down, when the feed lever movable seat 5 drives the feed lever body 6 to move up and down, only relative rotation can occur between the feed lever body 6 and the feed lever fixed seat 7 through the second pin shaft. The cooperation between the support flange 44 and the third through groove 45 realizes the driving of the upper transmission sleeve body 9 during the up and down movement of the feed lever body 6, so as to realize the precise control of the up and down movement and the self-rotation of the tool bar shaft body 12 for feed and retraction.

[0101] Again assist Figure 4 , in this embodiment, a thrust ball bearing is provided at the contact part between the transmission sleeve adapter seat 8 and the upper transmission sleeve body 9. A first locking nut is connected to the bottom of the transmission sleeve adapter seat 8, and the first locking nut is located below the thrust ball bearing; the main shaft drive pulley 17 is configured with a main shaft drive motor 46; the main shaft drive motor 46 and the main shaft drive pulley 17 are connected by a main shaft transmission belt; a second locking nut is provided between the main shaft drive pulley 17 and the main shaft sleeve 18.

[0102] Specifically, the first locking nut locks the thrust ball bearing at the contact position between the transmission sleeve adapter seat 8 and the upper transmission sleeve body 9. The upper transmission sleeve body 9 can rotate relative to the transmission sleeve adapter seat 8. When driving the main shaft body 13, the entire tool bar shaft cam sleeve 11, the tool bar shaft body 12 and the transmission sleeve roller shaft 14 can rotate simultaneously, so as to realize the tool bar shaft body 12 driving the bearing bush processing cutter head 20 to perform oil line processing.

[0103] Among them, the tool shank axis body 12 drives the bearing bush machining cutter head 20 to rotate following the main shaft body 13 to realize the control of the oil line track, and the tool shank axis body 12 rotates relative to the main shaft body 13 itself to realize the control of the machining depth and width of the oil line.

[0104] Among them, the second locking nut plays a supporting role for the main shaft drive pulley 17, and the main shaft sleeve 18 plays a protective role for the main shaft body 13. At the same time, the upper end positioning cone disk 19 is installed through the main shaft sleeve 18 to facilitate the positioning of the bearing bush. A bearing is provided between the main shaft body 13 and the main shaft sleeve 18, and the main shaft body 13 can rotate relative to the main shaft sleeve 18.

[0105] Auxiliary Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , in this embodiment, symmetrically elevated protrusions 47 are provided at the upper end of the lower transmission sleeve body 10, the top of the elevated protrusions 47 contacts the bottom of the upper transmission sleeve body 9, and a roller shaft installation gap 15 is formed at the side of the elevated protrusions 47; the transmission sleeve roller shafts 14 are symmetrically arranged on both sides of the elevated protrusions 47, and roller shaft mounting seats 48 are connected to the ends of the transmission sleeve roller shafts 14; a main shaft reducing sleeve 49 is provided inside the lower transmission sleeve body 10, a main shaft reducing sliding key 50 is provided between the main shaft reducing sleeve 49 and the lower transmission sleeve body 10, and the lower transmission sleeve body 10 moves up and down relative to the main shaft reducing sleeve 49 through the main shaft reducing sliding key 50.

[0106] Specifically, the purpose of designing the elevated protrusions 47 is to form a roller shaft installation gap 15 between the lower transmission sleeve body 10 and the upper transmission sleeve body 9. The transmission sleeve roller shafts 14 are arranged in the roller shaft installation gap 15 through the roller shaft mounting seats 48, and the transmission sleeve roller shafts 14 can rotate relative to the roller shaft mounting seats 48 themselves. Furthermore, when the tool shank axis cam sleeve 11 moves up and down, it can rotate under the action of the transmission sleeve roller shafts 14.

[0107] Specifically, since the transmission sleeve adapter seat 8 moves up and down driven by the feed lever body 6, the upper transmission sleeve body 9 and the lower transmission sleeve body 10 connected to the transmission sleeve adapter seat 8 will also move up and down accordingly. In order to realize the up and down movement while the upper transmission sleeve body 9 and the lower transmission sleeve body 10 are rotating, a main shaft reducing sliding key 50 is provided between the main shaft reducing sleeve 49 and the lower transmission sleeve body 10, and the lower transmission sleeve body 10 moves up and down relative to the main shaft reducing sleeve 49 through the main shaft reducing sliding key 50. Furthermore, the linear motion of the linear driving member 4 is converted into a rotational motion, and at the same time, it will not interfere with the rotation of the upper transmission sleeve body 9 and the lower transmission sleeve body 10.

[0108] It should be emphasized that the design purpose of the spindle diameter-changing sleeve 49 and the spindle diameter-changing sliding key 50 is to enable the spindle body 13 to change its diameter up and down. During the up-and-down diameter-changing process, the linear motion is used to realize the self-rotation of the tool rod shaft body 12 through the tool rod shaft cam sleeve 11 and the driving sleeve roller shaft 14.

[0109] Auxiliary Figure 1 、 Figure 2 、 Figure 3 and Figure 4 In this embodiment, a sleeve upper fixing base plate 51 is provided on the outer periphery of the upper end of the spindle sleeve 18, and the linear driving member 4 is connected to the edge of the sleeve upper fixing base plate 51; the spindle driving motor 46 is connected to the side of the sleeve upper fixing base plate 51; a sleeve lower fixing base plate 52 is provided on the outer periphery of the lower end of the spindle sleeve 18, and a column body 53 is connected between the sleeve lower fixing base plate 52 and the sleeve upper fixing base plate 51.

[0110] Specifically, the sleeve upper fixing base plate 51 plays a role in installing and supporting the spindle sleeve 18 and the spindle driving motor 46, and the column body 53 plays a role in supporting the sleeve lower fixing base plate 52 and the sleeve upper fixing base plate 51. At the same time, the feed lever fixing base 7 is supported by the column fixing top plate 54 and the sleeve upper fixing base plate 51. The upper end cone plate fixing base plate 60 plays a role in installing and positioning the upper end positioning cone plate 19, and the base bottom plate 55 plays a role in supporting the entire column body 53.

The bottom of the lower end positioning cone sleeve 56 is at the center of the base bottom plate 55, and the upper end of the lower end positioning cone sleeve 56 corresponds to the lower end of the first bearing positioning fixture 36 / second bearing positioning fixture 37; the lower end positioning cone sleeve 56 is connected to a clamping beam 57, the upper part of the clamping beam 57 is connected to a clamping adjustment oil cylinder 58, and the top end of the clamping adjustment oil cylinder 58 is connected to the upper end cone plate fixing base plate 60; a chip suction cover 59 is communicated with the bottom of the lower end positioning cone sleeve 56.

[0112] Specifically, the lower positioning cone sleeve 56 plays a role in positioning the first bearing shell positioning fixture 36 or the second bearing shell positioning fixture 37, ensuring the stability of the bearing shell when the first bearing shell positioning fixture 36 or the second bearing shell positioning fixture 37 is at the processing station. Among them, the clamping adjustment oil cylinder 58 can drive the entire lower positioning cone sleeve 56 to approach the first bearing shell positioning fixture 36 or the second bearing shell positioning fixture 37 through the clamping beam 57, and then bring the upper end of the first bearing shell positioning fixture 36 or the second bearing shell positioning fixture 37 close to the upper positioning cone disc 19, realizing the positioning of the upper positioning cone disc 19 to the semi-bearing shells spliced into a cylindrical shape inside the first bearing shell positioning fixture 36 or the second bearing shell positioning fixture 37, ensuring the stability of the bearing shell during the processing. Among them, the chip suction hood 59 can be docked to the dust suction system to collect the debris generated during the bearing shell processing.

[0113] The present invention also provides a process for connecting the oil line of the semi-bearing shell docking vehicle, using the above-mentioned semi-bearing shell docking vehicle oil line system, including the following steps:

[0114] S1. The semi-bearing shells to be processed are docked into a cylindrical shape by the semi-bearing shell circular splicing assembly 61 and conveyed to the feeding position;

[0118] S5. The up and down movement of the transmission sleeve adapter seat 8 is converted into the self-rotation movement of the tool bar shaft body 12 through the tool bar shaft cam sleeve 11 and the transmission sleeve roller shaft 14;

[0119] S6. The self-rotation movement of the tool bar shaft body 12 enables the bearing shell processing tool disc 20 carried thereon to perform the feed and retraction actions for the bearing shell oil line processing;

[0123] In summary, the present invention is provided with an oil line processing mechanism 1, a semi-axle tile circular splicing assembly 61, a circular splicing semi-axle tile transfer assembly 2, a circular splicing semi-axle tile station switching assembly 3, and a circular splicing semi-axle tile processing and offline assembly 62; the oil line processing mechanism 1 is provided with a linear drive member 4, a feed lever movable seat 5, a feed lever body 6, a feed lever fixed seat 7, a transmission sleeve adapter seat 8, an upper transmission sleeve body 9, a lower transmission sleeve body 10, a tool bar shaft cam sleeve 11, a tool bar shaft body 12, a main shaft body 13, and a transmission sleeve roller shaft 14; the upper end of the linear drive member 4 is connected to the feed lever movable seat 5, and one end of the feed lever movable seat 5 is hinged to the feed lever body 6; the other end of the feed lever body 6 is hinged to the feed lever fixed seat 7, and the middle of the feed lever body 6 is hinged to the transmission sleeve adapter seat 8; the upper end of the upper transmission sleeve body 9 is connected to the lower end of the transmission sleeve adapter seat 8, the upper end of the lower transmission sleeve body 10 is connected to the lower end of the upper transmission sleeve body 9, and a roller shaft installation gap 15 is formed between the lower transmission sleeve body 10 and the upper transmission sleeve body 9; the upper end of the tool bar shaft cam sleeve 11 is inside the upper transmission sleeve body 9, and the lower edge of the tool bar shaft cam sleeve 11 is exposed in the roller shaft installation gap 15; the top end of the tool bar shaft body 12 is inside the tool bar shaft cam sleeve 11, the lower end of the tool bar shaft body 12 extends out of the bottom of the main shaft body 13, and the tool bar shaft body 12 is at a preset eccentric position of the main shaft body 13; the transmission sleeve roller shaft 14 is arranged in the roller shaft installation gap 15, the tool bar shaft cam sleeve 11 is formed with a spiral track groove 16, and the transmission sleeve roller shaft 14 is in contact with the spiral track groove 16; a main shaft drive pulley 17 is arranged below the lower transmission sleeve body 10, and the main shaft body 13 passes through the center of the main shaft drive pulley 17; a main shaft sleeve 18 is arranged below the main shaft drive pulley 17, and the main shaft body 13 passes through the center of the main shaft sleeve 18; the bottom of the main shaft sleeve 18 is connected with an upper end positioning cone plate 19; the bottom of the tool bar shaft body 12 is connected with a bearing shell processing tool disc 20, and the bearing shell processing tool disc 20 is inside the upper end positioning cone plate 19; the semi-axle tile circular splicing assembly 61 docks the semi-axle tiles to be processed into a cylindrical shape and conveys them to the loading position; the circular splicing semi-axle tile transfer assembly 2 transfers the semi-axle tiles docked into a cylindrical shape at the loading position to the circular splicing semi-axle tile station switching assembly 3; the circular splicing semi-axle tile station switching assembly 3 transfers the unprocessed semi-axle tiles docked into a cylindrical shape to the upper end positioning cone plate 19 of the oil line processing mechanism 1; the bearing shell processing tool disc 20 performs oil line processing on the semi-axle tiles docked into a cylindrical shape transferred to the upper end positioning cone plate 19; at the same time, the circular splicing semi-axle tile station switching assembly 3 transfers the semi-axle tiles docked into a cylindrical shape that have been processed by the bearing shell processing tool disc 20 to the unloading position; the circular splicing semi-axle tile processing and offline assembly 62 outputs the processed semi-axle tiles docked into a cylindrical shape at the unloading position. The semi-axle tiles to be spliced into a cylindrical shape are arranged on the split bearing shell slideway 63, and the openings of the semi-axle tiles face the bearing shell stop arm 66, so as to prevent the semi-axle tiles from being back-to-back and make the semi-axle tile openings face each other to form a circle.Among them, the side of the bearing bush fork 67 facing the bearing bush stop arm 66 forms a block, causing the half bearing bush to slide from the other side of the bearing bush stop arm 66 onto the feeding chute 65. Immediately afterwards, the side of the bearing bush fork 67 facing the other side of the bearing bush stop arm 66 forms a block, causing the half bearing bush on the side of the bearing bush stop arm 66 that is released from the block to slide onto the feeding chute 65. The half bearing bushes sliding onto the two feeding chutes 65 front and back are spliced end to end to form a circle. The reversal of the bearing bush fork 67 is achieved by driving the swing shaft 70 through the fork driving cylinder 71. For the half bearing bushes that slide onto the feeding chute 65 and are spliced into a circle, the claw driving cylinder drives the pusher claw 68 through the claw adapter plate 72, and the pusher claw 68 moves along the feeding chute 65 to push the half bearing bushes spliced into a circle to the feeding position. The design of the pushing avoidance gap 69 avoids the interference of the split bearing bush chute 63 when the pusher claw 68 moves along the feeding chute 65, and the support of the split bearing bush chute 63 is realized through the chute adapter plate 64. The feed lever movable seat 5, the feed lever body 6, the feed lever fixed seat 7, and the transmission sleeve adapter seat 8 form a lever structure. The connection position between the feed lever fixed seat 7 and the feed lever body 6 forms a fulcrum. The linear drive member 4 can adopt a double-headed oil cylinder. When the linear drive member 4 drives the feed lever movable seat 5 upward, the central position of the feed lever body 6 moves upward, and then the transmission sleeve adapter seat 8 moves upward; when the linear drive member 4 drives the feed lever movable seat 5 downward, the central position of the feed lever body 6 moves downward, and then the transmission sleeve adapter seat 8 moves downward. The lever design makes it easier to drive the transmission sleeve adapter seat 8. The transmission sleeve adapter seat 8 drives the upper transmission sleeve body 9 to move up and down. During the up and down movement of the upper transmission sleeve body 9, since the transmission sleeve roller 14 and the tool bar shaft cam sleeve 11 are in contact through the spiral track groove 16, the tool bar shaft cam sleeve 11 can be rotated. The rotation of the tool bar shaft cam sleeve 11 drives the connected tool bar shaft body 12 to rotate, and the rotation of the tool bar shaft body 12 drives the connected bearing bush processing tool disc 20 to rotate. Since the tool bar shaft body 12 is eccentrically designed relative to the main shaft body 13, the rotation of the tool bar shaft body 12 driving the bearing bush processing tool disc 20 can achieve the feeding and retracting actions. Feeding means that the bearing bush processing tool disc 20 rotates and offsets to contact the inner wall of the bearing bush where the oil line is processed, and retracting means that the bearing bush processing tool disc 20 rotates and offsets to disengage from the inner wall of the bearing bush where the oil line is processed. That is, through the eccentric design, the rotation of the tool bar shaft body 12 driving the bearing bush processing tool disc 20 will have a radial offset, and the feeding and retracting are achieved through this offset. After feeding, the bearing bush processing tool disc 20 will rotate integrally under the carrying of the main shaft body 13. Since the bearing bush processing tool disc 20 contacts the inner wall of the bearing bush, the processing of the bearing bush oil line is realized. The processing depth of the oil line is controlled by controlling the feeding amount, and the processing width of the oil line is controlled by controlling the up and down movement amount of the bearing bush processing tool disc 20.The present invention realizes the separate drive control of the spindle body 13 and the tool bar shaft body 12. The spindle body 13 only needs to perform a rotating motion and does not need to perform an offset motion. The lever design of the feed lever movable seat 5, the feed lever body 6, the feed lever fixed seat 7, and the transmission sleeve adapter seat 8 enables the tool bar shaft body 12 to realize the conversion from a linear motion to its own rotational motion by means of the tool bar shaft cam sleeve 11 and the transmission sleeve roller shaft 14. The self-rotation of the eccentrically designed tool bar shaft body 12 can control the feed and push tool actions of the bearing shell processing tool disc 20 connected thereto, which is beneficial to controlling the processing dimensions and accuracy of the bearing shell oil line; it can realize the loading and unloading of the semi-circular half bearing shells being butted into a cylindrical shape, and at the same time, the semi-circular half bearing shells are butted into a cylindrical shape for processing, avoiding the generation of burrs in the tool exit direction during the individual processing of the half bearing shells, improving the oil line processing quality, and reducing the processing cost.
