Description

Technical Field

[0001] This invention relates to the technical field of shock absorber bearings, and particularly to a high-efficiency ball loading device for shock absorber bearings. Background Technology

[0002] The bearings of automotive shock absorbers are generally flat bearings, also known as pressure bearings. This support, combined with the steering knuckle, also serves as the pivot point for left and right steering. The flat bearing is located at the top of the shock absorber, between the spring and the top mount of the shock absorber. It must withstand the pressure from above and below while also being able to rotate freely. The existing patent number 201510942036.6, entitled "An Automatic Steel Ball Loading Machine for a Planar Bearing," includes a ball lowering mechanism and a ball separating mechanism. The ball separating mechanism comprises a ball separating mold, a steel ball arranging ring, a guide groove mold, and a ball guard sleeve. A second cylinder is installed at the top of the ball separating mechanism, allowing the entire mechanism to move downwards above the planar bearing. The rotating shaft of the ball separating mold is connected to a first stepper motor. The ball separating mold has evenly spaced ball separating teeth and is installed inside the steel ball arranging ring. A third cylinder is mounted on a third cylinder mounting plate and is fixedly connected to the steel ball arranging ring. Below the ball separating mold is the guide groove mold, which cooperates with the outer ball guard sleeve to form a falling channel for each steel ball, allowing the steel balls to pass through and fall into the rolling groove of the planar bearing placed on the worktable. It dispenses steel balls into the ball-dispensing mold. Then, the second cylinder drives the entire ball-dispensing mechanism to descend to the bottom, and the third cylinder drives the steel ball arrangement ring to descend to open the falling channel. However, it does not have a pre-loading function, and dispensing and falling of balls cannot be carried out simultaneously, resulting in low efficiency. In addition, it requires an additional driving force to open the falling channel and close the ball-dropping tube. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a high-efficiency ball loading device for shock absorber bearings, which can pre-load steel balls during the ball dropping process and automatically open and close the dropping channels of the ball dropping assembly and the pre-loading ball assembly, so that the ball dropping assembly can move out and in to the loading position, thereby improving efficiency.

[0007] Furthermore, the lower inner guide 10 is composed of a middle stop post 10.2 connecting the upper and lower abutment posts 10.1 and guide posts 10.3. A first inclined guide surface 10.4 is provided between the stop post 10.2 and the guide post 10.3. A stepped hole 10.5 is opened in the middle of the lower inner guide 10, which slides on the fixed post 9 and abuts against the limiting plate 11. An outer inclined surface 10.6 is provided at the upper end of the abutment post 10.1.

[0008] Furthermore, the lower outer guide 13 is composed of an annular ring 13.1 connecting the extensions 13.2 on both sides. The annular ring 13.1 is coaxially arranged with the lower inner guide 10 and the lower ball mold 12. The annular groove 13.3 for fixing the lower ball mold 12 is coaxially formed inside the annular ring 13.1. A second inclined guide surface 13.4 is provided between the annular groove 13.3 and the inner wall of the annular ring 13.1.

[0009] Furthermore, a disassembly position is formed between the outer wall of the stop post 10.2, the ball groove, and the bottom surface of the annular groove 13.3, and a falling channel is formed between the first inclined guide surface 10.4, the second inclined guide surface 13.4, the outer wall of the guide post 10.3, and the inner wall of the ring 13.1.

[0010] Furthermore, the pre-loaded ball assembly 15 includes a fixing sleeve 15.1 connected to the stabilizing platform 6 via a fixing block 14. The fixing sleeve 15.1 is slidably fitted with an upper inner guide 15.3 that can be lifted by the stop post 10.2. A limiting ring 15.2 is coaxially provided at the bottom of the fixing sleeve 15.1 to limit the upper inner guide 15.3. An upper outer guide 15.5 is rotatably provided in the middle of the stabilizing platform 6. An upper ball-splitting mold 15.4 is fixed inside the upper outer guide 15.3. The upper inner guide 15.3, the upper outer guide 15.5, and the upper ball-splitting mold 15.4 are coaxially arranged.

[0011] Furthermore, the servo motor 17 is mounted upwards on the stable platform 6, and a gear 19 is keyed onto the output shaft of the servo motor 17. A gear ring 18 that meshes with the gear 19 is coaxially mounted on the upper outer guide 15.5.

[0012] Furthermore, the lower ball assembly 16 includes a lower ball rigid tube 16.4 and a support block 16.1 vertically disposed on the stable platform 6. A second guide rod 16.2 is laterally slidably mounted on the support block 16.1. A limit post is provided at the end of the second guide rod 16.2. A stop block 16.3 that cooperates with the outer inclined surface 10.6 and the stop post 10.1 is connected to the left end of the second guide rod 16.2. An elastic element connecting the stop block 16.3 and the support block 16.1 is sleeved on the second guide rod 16.2. The lower ball rigid tube 16.4 is vertically and adjustablely inserted through the stop block 16.3.

[0013] Furthermore, the lower ball hard tube 16.4 is locked to the abutment block 16.3 by a locking bolt.

[0014] The advantages of this invention are: the pre-loading of steel balls can be completed during the ball dropping process, and the falling channels of the ball dropping assembly and the pre-loading ball assembly can be automatically opened and closed, so that the ball dropping assembly can be moved out and in to the dispensing position, thereby improving efficiency; the third cylinder drives the lifting block to lift the shock absorber bearing on the positioning plate, the second cylinder drives the slider to move one position to the right, the third cylinder drives the frame plate to descend and reset, the shock absorber bearing is fitted into the positioning plate for positioning, and the second cylinder drives the slider to move to the left and reset, thereby moving the shock absorber bearing one position to the right; Under the influence of gravity, the lower inner guide descends synchronously with the limiting plate and the fixing column. The lower inner guide detaches from the upper inner guide and the stop block. The upper inner guide of the pre-assembled ball assembly descends to the bottom under gravity to close the falling channel. After the lower inner guide stops against the positioning plate, the lower outer guide and the lower ball mold continue to descend to open the falling channel. The steel ball falls along the falling channel to the shock absorber bearing. Under the influence of gravity, the lower inner guide rises with the limiting plate and the fixing column, thus closing the falling channel. It then pushes against the upper inner guide of the pre-assembled ball assembly, causing the pre-assembled ball assembly to open the falling channel. The outer inclined surface drives the stop block of the lower ball assembly, carrying the lower ball tube, to move away. The stop block abuts against the outer wall of the stop column to maintain the moved-away state. The stop column is used to form the sub-assembly position. The first inclined guide surface and the guide column are used to form the lower... The drop channel is formed between the outer wall of the stop post, the bottom surface of the ball groove and the ring groove, and between the first inclined guide surface, the second inclined guide surface, the outer wall of the guide post and the inner wall of the ring. The servo motor drives the upper outer guide to rotate one revolution, and the upper outer guide takes the upper ball mold to rotate one revolution, so that the lower ball hard tube that moves into the ball groove of the upper ball mold will fill the steel ball into the ball groove. The lower inner guide descends, and the abutment block disengages from the abutment post and the outer inclined surface under the elastic action. The lower ball hard tube moves into the upper ball groove of the upper ball mold. The lower inner guide rises, and the outer inclined surface drives the abutment block to move to the right with the lower ball hard tube. The abutment block abuts against the outer wall of the abutment post and remains stationary. The lower ball hard tube moves out of the ball groove of the upper ball mold and is located above the upper ball mold. The bottommost steel ball is blocked by the upper end face of the upper ball mold. Attached Figure Description

[0028] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings.

[0029] See Figures 1 to 13This invention provides a high-efficiency ball loading device for shock absorber bearings, comprising a base 1, a horizontal plate 2 arranged horizontally above the base 1, positioning discs 3 for positioning the shock absorber bearings equidistantly arranged on the horizontal plate 2, a vertical block 5 and a shifting assembly 4 for shifting the shock absorber bearings arranged on the base 1, the shifting assembly 4 including a slider 4.2 that slides left and right on the base 1 and is driven by a second cylinder 4.1, a slide rail arranged horizontally on the base to accommodate the slider, a third cylinder 4.3 symmetrically arranged on the front and rear sides of the slider 4.2, a frame plate 4.4 horizontally arranged at the piston rod end of the third cylinder 4.3, lifting blocks 4.5 for lifting the shock absorber bearings to the positioning discs 3 equidistantly mounted on the frame plate 4.4, the third cylinder driving the frame plate and the lifting blocks to rise, the lifting blocks lifting the shock absorber bearings on the positioning discs, the second cylinder driving the slider and its components to move one position to the right, the third cylinder driving the frame plate and its lifting blocks and the shock absorber bearings to move... The shock absorber bearing is lowered and reset, and then fitted into the positioning plate for positioning. The second cylinder drives the slider and its components to move to the left and reset, thereby shifting the shock absorber bearing one position to the right. The upright block 5 is equipped with a stabilizing platform 6 and a first cylinder 7. The piston rod end of the first cylinder 7 is longitudinally provided with a connecting plate 8. The connecting plate 8 is equipped with a ball drop assembly that slides onto the stabilizing platform 6. The stabilizing platform 6 is equipped with a lower ball assembly 16 and a pre-loaded ball assembly 15 driven by a servo motor 17. The lowering ball drop assembly disengages from the pre-loaded ball assembly 15 and the lower ball assembly 16 in sequence. The pre-loaded ball assembly 15 closes the falling channel, and the lower ball assembly 16 moves in elastically. The steel ball is distributed from the lower ball assembly 16 to the pre-loaded ball assembly 15 to complete the pre-loading. The ball drop assembly abuts against the positioning plate 3 to drop the ball onto the shock absorber bearing. The rising ball drop assembly moves the lower ball assembly 16 out, and the ball drop assembly opens the falling channel of the pre-loaded ball assembly 15. The steel ball distributed by the pre-loaded ball assembly 15 falls onto the ball drop assembly. The first cylinder drives the connecting plate to descend, which in turn lowers the ball-dropping assembly. The ball-dropping assembly disengages from the pre-loaded ball assembly and then the lower ball assembly. The pre-loaded ball assembly closes the descent channel (the descent channel is blocked after the steel balls are loaded into the pre-loaded ball assembly). The lower ball assembly elastically moves into the loading position of the pre-loaded ball assembly. Simultaneously, the shifting assembly moves the shock absorber bearing to the positioning plate. The servo motor drives the pre-loaded ball assembly, and the steel balls are loaded from the lower ball assembly into the pre-loaded ball assembly to complete the pre-loading. After the ball-dropping assembly abuts against the positioning plate, it opens the lower ball assembly. The ball dropper assembly, which is pre-loaded with steel balls, falls into the shock absorber bearing. The first cylinder drives the connecting plate to rise, which in turn lifts the ball dropper assembly. The ball dropper assembly first contacts the lower ball assembly, which then moves out of the pre-loaded ball assembly's loading position (the steel balls inside the lower ball assembly are blocked and will not roll down the dropper assembly). The ball dropper assembly then contacts the pre-loaded ball assembly, causing it to open the dropper assembly's loading channel. The steel balls pre-loaded in the pre-loaded ball assembly fall into the ball dropper assembly, while the shifting assembly shifts the shock absorber bearing.

[0030] The ball-dropping assembly includes a fixed column 9 vertically connected to the bottom of the connecting plate 8 and a first guide rod 20. A lower inner guide 10 is slidably mounted on the outside of the fixed column 9. A limiting plate 11 for limiting the lower inner guide 10 is coaxially provided at the bottom of the fixed column 9. A lower outer guide 13 is connected to the bottom of the first guide rod 20 slidably mounted on the stable platform 6. A lower ball-splitting mold 12 is fixed inside the lower outer guide 13. Ball grooves are evenly distributed circumferentially along the axis of the inner wall of the lower ball-splitting mold 12. The connecting plate, along with the fixing post, limiting plate, and first guide rod, descends. The lower outer guide and lower ball mold descend with the first guide rod. The lower inner guide, under the influence of gravity, descends synchronously with the limiting plate and fixing post. The lower inner guide disengages from the upper inner guide and the stop block of the lower ball assembly of the pre-assembled ball assembly. The upper inner guide of the pre-assembled ball assembly descends to the bottom under the influence of gravity to close the falling channel. The stop block, carrying the lower ball rigid tube, moves into the disassembly position of the pre-assembled ball assembly under the influence of elasticity. Then, the lower inner guide rests against the positioning plate and remains stationary. The lower outer guide and lower ball mold continue to descend to open the lower ball assembly. The steel ball falls along the drop channel to the shock absorber bearing. Then, the connecting plate, along with the fixed column, the limiting plate, and the first guide rod, rises. The lower outer guide and the lower ball mold rise with the first guide rod. The lower inner guide rises with the limiting plate and the fixed column under the action of gravity, thereby closing the drop channel. The lower inner guide first moves the abutment block of the lower ball assembly, along with the lower ball hard tube, out of the pre-assembled ball assembly's disassembly position, and then pushes the upper inner guide of the pre-assembled ball assembly, causing the pre-assembled ball assembly to open the drop channel. The steel balls disassembled in the pre-assembled ball assembly fall along the drop channel to the drop ball assembly and are disassembled.

[0031] See Figures 9-12 The lower inner guide 10 is composed of a central stop post 10.2 connecting upper and lower abutment posts 10.1 and guide posts 10.3. A first inclined guide surface 10.4 is provided between the stop post 10.2 and the guide post 10.3. A stepped hole 10.5 is provided in the middle of the lower inner guide 10, which slides onto the fixed post 9 and abuts against the limiting plate 11. An outer inclined surface 10.6 is provided at the upper end of the abutment post 10. The outer inclined surface drives the abutment block of the lower ball assembly to move away with the lower ball hard tube. The abutment block abuts against the outer wall of the abutment post to maintain the moved state. The stop post is used to form a dispensing position, and the first inclined guide surface and guide post are used to form a falling channel.

[0032] See Figure 8 , Figure 13 The lower outer guide 13 is composed of a ring 13.1 connecting extensions 13.2 on both sides. The ring 13.1 is coaxially arranged with the lower inner guide 10 and the lower ball mold 12. An annular groove 13.3 for fixing the lower ball mold 12 is coaxially formed inside the ring 13.1. A second inclined guide surface 13.4 is provided between the annular groove 13.3 and the inner wall of the ring 13.1. A guide groove corresponding to the ball groove is formed on the inner wall of the ring. A disassembly position is formed between the outer wall of the stop post 10.2, the ball groove, and the bottom surface of the annular groove 13.3. A falling channel is formed between the first inclined guide surface 10.4, the second inclined guide surface 13.4, the outer wall of the guide post 10.3, and the inner wall of the ring 13.1.

[0033] The pre-assembled ball assembly 15 includes a fixed sleeve 15.1 connected to the stabilizing platform 6 via a fixed block 14. An upper inner guide 15.3 is slidably mounted on the outside of the fixed sleeve 15.1 and can be lifted by a stop post 10.2. A limiting ring 15.2 for limiting the upper inner guide 15.3 is coaxially provided at the bottom of the fixed sleeve 15. The upper outer guide 15.5 is rotatably provided in the middle of the stabilizing platform 6. An upper ball-splitting mold 15.4 is fixed inside the upper outer guide 15.3. The upper inner guide 15.3, the upper outer guide 15.5, and the upper ball-splitting mold 15.4 are coaxially arranged. The upper inner guide has the same structure as the lower inner guide, except for the abutment part. The outer wall of the guide post of the upper inner guide can overlap with the outer wall of the stop post of the lower inner guide. The upper and lower ball molds have the same structure. The inner walls of the upper and lower outer guides have the same structure, but their dimensions are different. A falling channel is formed between the upper inner guide and the upper outer guide. The ball groove of the lower ball mold is smaller than that of the upper ball mold. The descending lower inner guide detaches from the upper inner guide. The upper inner guide is subjected to gravity. The ball descends to the bottom (the upper inner guide is stopped by the limit ring), thus closing the falling channel. The servo motor drives the upper outer guide to rotate one revolution, and the upper outer guide rotates the upper ball mold one revolution, causing the lower ball hard tube, which has moved into the ball groove of the upper ball mold, to pack the steel balls into the ball groove. The stop post of the lower inner guide pushes against the upper inner guide, causing the pre-loaded ball assembly to open the falling channel. The steel balls packed in the ball groove of the upper ball mold fall along the falling channel into the ball groove of the lower ball mold and are packed.

[0034] The servo motor 17 is mounted upwards on the stable platform 6. A gear 19 is keyed onto the output shaft of the servo motor 17. A gear ring 18, which meshes with the gear 19, is coaxially mounted on the upper outer guide 15.5. The servo motor drives the gear to rotate, the gear drives the gear ring to rotate, and the gear ring rotates the upper outer guide and the upper ball mold.

[0035] The lower ball assembly 16 includes a lower ball rigid tube 16.4 and a support block 16.1 vertically mounted on the stable platform 6. A second guide rod 16.2 is laterally slidable on the support block 16.1. A limit post is provided at the end of the second guide rod 16.2. The left end of the second guide rod 16.2 is connected to a stop block 16.3 that cooperates with the outer inclined surface 10.6 and the stop post 10.1. An elastic element connecting the stop block 16.3 and the support block 16.1 is sleeved on the second guide rod 16.2. The lower ball rigid tube 16.4 is vertically and adjustablely inserted through the stop block 16.3. The elastic element is a pre-compressed spring. The cross-section of the second guide rod consists of a square in the middle connected to an arc on the upper and lower sides. The lower ball hard tube is a steel pipe, which can be connected to the ball barrel above the steel pipe through a flexible hose. The flexible hose is in a bent state, and its bottom can move with the lower ball hard tube. The steel ball falls from the steel ball barrel, the flexible hose, and the lower ball hard tube into the ball groove of the upper ball mold in sequence. The distance between the lower end face of the lower ball steel tube and the upper end face of the upper ball mold is less than 1 / 3 of the diameter of the steel ball. The lower inner guide descends, and the abutment block disengages from the abutment post and the outer inclined surface under elastic action. The lower ball hard tube moves into the upper ball groove of the upper ball mold. As the upper ball mold rotates, the steel balls in the lower ball hard tube are distributed into the ball groove. The lower inner guide rises, and the outer inclined surface drives the abutment block to move the lower ball hard tube to the right. The abutment block abuts against the outer wall of the abutment post and remains stationary. The lower ball hard tube moves out of the ball groove of the upper ball mold and is located above the upper ball mold. The lowest steel ball is blocked by the upper end face of the upper ball mold.

[0036] The lower ball hard tube 16.4 is locked to the abutment block 16.3 by a locking bolt. The locking bolt is screwed to the abutment block. Loosening the locking bolt allows adjustment of the upper and lower position of the lower ball hard tube, and then tightening the locking bolt locks the lower ball hard tube.

[0037] The specific workflow of this invention is as follows: The first cylinder drives the connecting plate to descend. The connecting plate, along with the fixing column, limiting plate, and first guide rod, descends. The lower outer guide and lower ball mold descend with the first guide rod. The lower inner guide, under the action of gravity, descends synchronously with the limiting plate and fixing column. The lower inner guide disengages from the upper inner guide and the stop block of the pre-installed ball assembly. The upper inner guide descends to the bottom under the action of gravity to close the falling channel. The stop block, under elastic action, disengages from the stop column and outer inclined surface. The lower ball hard tube moves into the ball groove of the upper ball mold. Simultaneously, the third cylinder drives the frame plate and its lifting block and shock absorber bearing to descend. The shock absorber bearing is fitted into the positioning plate for positioning. The servo motor drives the gear to rotate. The gear drives the gear ring to rotate one revolution. The gear ring, along with the upper outer guide and upper ball mold, rotates one revolution. The steel ball is disassembled from the lower ball hard tube into the ball groove of the upper ball mold to complete the pre-installation. Figure 5 As shown, the lower inner guide then stops after hitting the positioning plate, while the lower outer guide and lower ball mold continue to descend to open the falling channel. The steel ball falls along the falling channel to the shock absorber bearing. At the same time, the second cylinder drives the slider and its components to move to the left, as shown. Figure 6As shown, the connecting plate then rises along with the fixed column, limiting plate, and first guide rod. The lower outer guide and lower ball mold rise with the first guide rod. The lower inner guide rises with the limiting plate and fixed column under gravity, thus closing the falling channel. The outer inclined surface of the lower inner guide drives the stop block to move to the right with the lower ball tube. The stop block abuts against the outer wall of the stop column and remains stationary. The lower ball tube moves out of the ball groove of the upper ball mold and is located above the upper ball mold. The lowest steel ball is blocked by the upper end face of the upper ball mold. The stop column of the lower inner guide pushes against the inner guide, causing the pre-assembled ball assembly to open the falling channel. The steel balls assembled in the ball groove of the upper ball mold fall into the ball groove of the lower ball mold along the falling channel and are assembled. At the same time, the third cylinder drives the frame plate and its lifting block to rise. The lifting block lifts the shock absorber bearing on the positioning plate. The second cylinder drives the slider and its components to move one position to the right. Figure 4 As shown.

[0038] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
