Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a dust cover feeding device. Background Technology

[0002] The tie rod assembly is a group of components on a car chassis, consisting of a lateral tie rod sub-assembly, a longitudinal tie rod sub-assembly, and upper and lower suspension ball joints. Each sub-assembly is assembled with the tie rod ball joints, and its main function is to transmit and execute steering force, affecting the directional angle changes of the front wheels, thereby enabling the car to drive correctly on the road.

[0003] For example, a ball joint assembly for an automotive tie rod has been designed and a Chinese patent has been applied for, with application number 201020558118.3 and publication number CN201794912U. This automotive tie rod ball joint assembly consists of a cover, ball seat, ball shell, lower flat spring, dust cover, upper spring, ball pin, hexagonal slotted thin nut, and cotter pin. A ball seat is installed inside the ball shell, a cover is installed at the lower opening of the ball shell, and a dust cover is installed at the upper opening of the ball shell. The lower end of the ball pin has a ball head, and the upper end has a ball pin rod. The ball head is positioned on the ball seat, and the ball pin rod is positioned in a through hole on the dust cover. An upper spring is installed on the upper end of the dust cover. A hexagonal slotted thin nut is threaded to the upper end of the ball pin rod, and a cotter pin is provided on the upper side of the hexagonal slotted thin nut, connecting to the ball pin rod. A ball shell shaft is horizontally arranged on the side of the ball shell, and the ball shell and the ball shell shaft are connected as a single unit.

[0004] After the automotive tie rod ball joint assembly is manufactured, its various components need to be assembled sequentially. Existing assembly machines typically have a centrally located circular turntable with equipment for each assembly process distributed around it. For the assembly of the dust cover, it needs to be transported horizontally and vertically after being picked up before being placed onto the workpiece to be assembled. This often requires a robotic arm connected to a slide that can move along a horizontal track, which in turn is fixed to a slide that can move up and down along a vertical track, thus feeding the dust cover. However, this robotic arm requires the coordination of the horizontal and vertical tracks, two slides, and corresponding transmission structures, resulting in a large overall size and occupying significant space around the turntable. This makes the entire assembly machine too bulky and unsuitable for use in spaces with limited capacity. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a dust cover feeding device, which solves the problem that the existing dust cover feeding devices occupy too much space around the turntable.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] A dust cover feeding device includes a support, a horizontally arranged turntable, a base connected to the turntable for placing workpieces, a chuck positioned above the base for clamping the dust cover, and a lifting drive unit connected to the support and capable of driving the chuck to rise and fall. The device is characterized in that a rotary drive unit is fixed on the support, a cylindrical rotating rod is vertically arranged above the turntable, the upper end of the rotating rod is connected to the rotary drive unit, and the dust cover feeding device further includes a long, horizontally arranged swing arm. One end of the swing arm is fixed to the lower end of the rotating rod, and a loading seat for placing the dust cover is fixed to the upper side of the other end of the swing arm. The rotary drive unit can drive the swing arm to swing horizontally around the axis of the rotating rod and move the loading seat between the chuck and the base.

[0008] During installation, the bracket of this dust cover feeding device is fixed outside the turntable and adjacent to it. When assembly is required, the workpiece, i.e., the semi-finished automotive tie rod ball joint with partially assembled components, is placed on the base on the turntable. The annular dust cover is manually placed on the loading seat in its initial position. The rotary drive unit drives the rotating rod to rotate circumferentially, causing the swing arm and loading seat to swing horizontally around the axis of the rotating rod to between the base and the chuck, i.e., above the base and below the chuck. The lifting drive unit drives the chuck to descend to the loading seat, the chuck jaws open, and after clamping the dust cover, the chuck rises under the drive of the lifting drive unit. The rotary drive unit drives the rotating rod, swing arm, and loading seat to reset, and the operator can continue feeding. Simultaneously, the lifting drive unit can drive the chuck to move downwards, conveying the dust cover to the workpiece on the base before resetting upwards. This completes the dust cover feeding process.

[0009] In this dust cover feeding device, the chuck is located above the base, the rotating rod is located above the turntable, and the lifting and rotating drive components are fixed on the bracket. For ease of assembly, both the lifting and rotating drive components can be arranged above the turntable. This not only eliminates the horizontal track and the slide structure that can move along the horizontal track, reducing the number of parts, size, and space occupied, but also places some feeding components above the turntable, making full use of the space above the center of the turntable and reducing the space occupied around the turntable. The structure is more compact, indirectly reducing the size of the assembly machine and improving its applicability. Furthermore, by separating horizontal and vertical feeding into two components, the translation and lifting processes are relatively independent. While the chuck is lowering to feed, the loading seat can be loaded simultaneously, improving feeding efficiency.

[0010] In the aforementioned dust cover feeding device, the rotary drive component is a swing cylinder. A block-shaped swing block is fixed to the outer side of the rotating rod. A limiting component is connected to the bracket. When the rotating rod rotates circumferentially, it can drive the swing block to swing around the axis of the rotating rod and abut against the side of the limiting component. Using a swing cylinder to drive the rotating rod to reciprocate is faster than using a drive motor with gears and racks for precise feeding. The limiting component is used to restrict the rotation angle of the rotating rod, so that the rotating rod can only swing back and forth between the loading and unloading positions.

[0011] In the aforementioned dust cover feeding device, the limiting component includes a block-shaped stop fixed on a bracket and a screw horizontally passing through the stop. The screw is threadedly connected to the stop, and the aforementioned swing block can abut against the end of the screw. By rotating the screw, the position of the screw end can be adjusted, thereby adjusting the rotatable angle of the swing block and the rotating rod to adapt to different usage requirements and improve the applicability.

[0012] In the aforementioned dust cover feeding device, the feeding seat is columnar and vertically arranged. The outer side of the feeding seat has a protruding, annular ring, and the upper end of the feeding seat is higher than the upper end of the protruding ring. The outer surface of the upper end of the protruding ring is conical, and the diameter of the conical surface gradually increases from top to bottom. The dust cover is annular, and when placed on the feeding seat, it abuts against the conical surface of the protruding ring to restrict the vertical position of the dust cover and facilitate clamping by the chuck. Simultaneously, the position of the upper end of the feeding seat being higher than the upper end of the protruding ring results in an upward-protruding columnar structure at the center of the upper side of the protruding ring, which is inserted into the dust cover to restrict its radial position, ensuring relative stability of the dust cover's position and facilitating subsequent feeding.

[0013] In the aforementioned dust cover feeding device, the base includes a seat body with a downwardly recessed hole at the top, a linear guide rail, a slider slidably mounted on the linear guide rail, and a V-shaped block fixed on the slider. The seat body has a through-hole on its side wall facing the V-shaped block. The slider can move along the linear guide rail and approach or move away from the seat body. The seat body is located directly below the chuck. The ball joint of an automotive tie rod has a long, round rod in the middle. Designing the base as a seat body and a V-shaped block provides two-point support, resulting in better positioning stability. The slidable slider allows the base to adapt to the assembly of workpieces of various sizes, making it widely applicable.

[0014] Compared with existing technologies, this dust cover feeding device has the following advantages:

[0015] 1. This dust cover feeding device not only eliminates the horizontal track and the slide structure that can move along the horizontal track, reducing the number of parts, size and space occupied, but also arranges some feeding parts above the turntable, making full use of the space above the center of the turntable, reducing the space occupied around the turntable, making the structure more compact, indirectly reducing the size of the assembly machine and improving the scope of application.

[0016] 2. This dust cover feeding device separates horizontal feeding and vertical feeding into two components, making the translation and lifting processes relatively independent. While the chuck is lowering to feed, the material can be fed to the loading seat, which improves the feeding efficiency. Attached Figure Description

[0019] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0020] like Figure 1 As shown, this dust cover feeding device includes a horizontally arranged disc-shaped turntable 2, a bracket 1 fixedly arranged outside the turntable 2 and adjacent to the turntable 2, a base 3 connected to the upper side of the turntable 2 at an eccentric position for placing the workpiece 12, a chuck 4 arranged above the base 3 for clamping the dust cover, and a lifting drive component 5 connected to the bracket 1 and capable of driving the chuck 4 to rise and fall.

[0021] The base 3 includes a vertically arranged cylindrical seat 3a with a recessed hole at the top, a linear guide rail 3b horizontally fixed to the upper side of the turntable 2, a slider 3c slidably arranged on the linear guide rail 3b, and a V-shaped block 3d fixed on the slider 3c. The V-shaped block 3d is fixed to the top of the slider 3c with the V-shaped opening facing upward. The slider 3c can move along the linear guide rail 3b and move closer to or away from the seat 3a. The seat 3a has a notch 3e through the side wall of the recessed hole facing the V-shaped block 3d. The seat 3a is located directly below the chuck 4. In this embodiment, the chuck 4 is a three-jaw chuck 4, which is an existing device. The three jaws of the chuck 4 are arranged downwards and can tighten or loosen the grip on the dust cover by opening and closing. The chuck 4 and the driving component for driving the opening and closing of the jaws of the chuck 4 are fixed on a slide. A vertically arranged guide rail is fixed on the bracket 1, and the slide can slide along the guide rail. The lifting driving component 5 is a cylinder, the cylinder body of which is fixed on the bracket 1, the piston rod is downwards, and the lower end of the piston rod is fixed to the slide. The turntable 2 is an existing component, which moves the base 3 to different work positions for different assembly processes by rotating it.

[0022] The support 1 has a plate-shaped top plate extending horizontally above the center of the turntable 2. The aforementioned lifting drive 5 is fixed to the upper side of the top rod, and the piston rod passes downward through the top plate. A swing cylinder, serving as a rotation drive 7, is also fixed to the upper side of the top plate near the center of the turntable 2. A cylindrical rotating rod 6 is vertically arranged above the turntable 2, and the upper end of the rotating rod 6 is connected to the output end of the rotation drive 7. The dust cover feeding device also includes a long, horizontally arranged swing arm 8 above the turntable 2. One end of the swing arm 8 is fixed to the lower end of the rotating rod 6, and a loading seat 9 for placing the dust cover is fixed to the upper side of the other end of the swing arm 8. The rotation drive 7 can drive the swing arm 8 to swing horizontally around the axis of the rotating rod 6 and move the loading seat 9 between the chuck 4 and the base 3.

[0023] Specifically, a cuboid-shaped swing block 10 is horizontally arranged below the top plate. The upper end of the rotating rod 6 passes through the eccentric position of the swing block 10 and is fixed to the swing block 10, so that the end of the swing block 10 farther from the rotating rod 6 can swing around the axis of the rotating rod 6 as the rotating rod 6 rotates. A limiting member 11 is fixed on the lower side of the top plate. When the rotating rod 6 rotates circumferentially, it can drive the swing block 10 to swing around the axis of the rotating rod 6 and abut against the side of the limiting member 11. In this embodiment, the limiting member 11 includes a block-shaped stop 11a fixed to the lower side of the top plate and a screw 11b horizontally passing through the stop 11a. The screw 11b is threadedly connected to the stop 11a, and the swing block 10 can abut against the end of the screw 11b.

[0024] The feeding seat 9 is columnar and vertically arranged. The outer side of the feeding seat 9 has a protruding annular ring 9a, and the upper end of the feeding seat 9 protrudes above the upper end of the ring 9a. That is, the position of the upper end of the feeding seat 9 is higher than the upper end of the ring 9a, so as to form a columnar limiting part above the ring 9a. The outer surface of the upper end of the ring 9a is a conical surface 9b, and the diameter of the conical surface 9b gradually increases from top to bottom.

[0025] When the dust cover feeding device needs to assemble the dust cover, the workpiece 12, that is, the semi-finished automobile tie rod ball head that has completed the assembly of some parts, is placed on the base 3 on the turntable 2. That is, the workpiece 12 is set horizontally, with one end inserted into the top of the seat 3a, and the round rod in the middle section of the workpiece 12 passes through the notch 3e and is placed on the V-shaped opening to support the workpiece 12.

[0026] Manually place the annular dust cover onto the loading seat 9 in its initial position, which is the position of the loading seat 9 when the swing arm 8 swings back to the point where the swing block 10 abuts against the screw 11b. The dust cover is annular and, when placed on the loading seat 9, it fits over the outside of the limiting part, with its lower end abutting against the conical surface 9b of the convex ring 9a.

[0027] The rotary drive 7 drives the rotating rod 6 to rotate circumferentially, causing the swing arm 8 and the loading seat 9 to swing horizontally around the axis of the rotating rod 6 to the extreme position on one side of the swing cylinder, that is, the loading seat 9 is located between the base 3 and the chuck 4. The lifting drive 5 drives the chuck 4 to descend to the loading seat 9, the jaws of the chuck 4 open, and after clamping the dust cover, the chuck 4 rises under the drive of the lifting drive 5. The rotary drive 7 drives the rotating rod 6, the swing arm 8 and the loading seat 9 to reset, and the operator can continue to load materials. At the same time, the lifting drive 5 can drive the chuck 4 to move down, transport the dust cover to the workpiece 12 on the base 3, and then open the jaws so that the dust cover is fitted onto the workpiece 12 and then moves up to reset. The feeding of the dust cover is completed.
