Description

Technical Field

[0001] This invention relates to the field of universal joint parts technology, specifically to a multi-degree-of-freedom sorting and assembling machine for universal joint parts. Background Technology

[0002] In the field of automotive transmission system manufacturing, the universal joint is a core component for realizing variable angle power transmission, and its assembly precision directly affects transmission efficiency and vehicle driving safety.

[0003] Universal joint types, such as cross-type and ball-cage type, and size differences require precise matching of parameters such as gasket thickness and aperture. Traditional sorting equipment, such as cross-belt sorters, rely on fixed paths and cannot adapt to the dynamically changing gasket requirements in the assembly process.

[0004] Traditional vibratory feeder systems use a fixed slide design, which can only handle parts of a single specification. Because the slide spacing is not adjustable, it is easy to cause stacking and jamming, resulting in a high sorting error rate and a long changeover time, making it unable to meet the needs of multi-variety mixed production.

[0020] This invention provides a multi-degree-of-freedom sorting and allocation machine for universal joint parts, such as... Figure 1-9 As shown, the device includes an annular base 101, which is annular in shape. The top of the annular base 101 has an outward-facing base opening ring 123. An annular rotating disk 102 is rotatably mounted inside the base opening ring 123. Several part storage compartments 120 are fixedly installed at the top of the annular rotating disk 102, arranged in a circular array along the top of the annular rotating disk 102. Two drive gearboxes 121 are fixedly mounted on both sides of the inner annular surface of the annular base 101, and the drive gearboxes 121 on both sides are symmetrically positioned. An arc-shaped channel support ring 125 is installed between 21. A conical sorting channel 124 is provided at the center between the channel support rings 125. A channel ring support frame 141 is installed and connected between the outer end face of the conical sorting channel 124 and the inner arc surface of the channel support ring 125. The channel ring support frame 141 provides a stable support effect. The conical sorting channel 124 is conical. An arc-shaped guide channel 131 with an opening and vertical connection is provided inside the conical sorting channel 124. The arc-shaped guide channel 131 is wider at the top and narrower at the bottom. The inner wall of the arc-shaped guide channel 131 is curved.

[0021] It should be further explained that the drive gearbox 121 is equipped with a transmission gear and a drive motor. The transmission gear meshes with the inner arc surface of the annular rotating disk 102. When the drive motor starts and drives the transmission gear to rotate, it in turn drives the annular rotating disk 102 to rotate along the guide of the lifting base 103 through meshing.

[0022] Furthermore, an output frame 107 is provided below the annular base 101, and a crossbeam support plate 108 of a cross frame is fixed on the top of the output frame 107. Two conveyor belt supports 109 are fixed on both sides of the top of the crossbeam support plate 108, and the two conveyor belt supports 109 are symmetrically positioned.

[0023] Furthermore, a conveyor belt roller 128 is rotatably mounted between the two conveyor belt supports 109. A conveyor belt wheel 129 is fixedly mounted on the outer end face of the conveyor belt roller 128. An output conveyor belt 111 is wound between the two conveyor belt wheels 129. A parts collection box 112 for output is placed at the top of the output conveyor belt 111. A conveyor motor 132 is fixedly mounted at one end of one conveyor belt support 109. One end of the conveyor belt roller 128 is poweredly connected to the conveyor motor 132.

[0024] It is worth further explaining that when the conveyor motor 132 starts, the conveyor belt roller 128 on one side can rotate, which in turn drives the conveyor belt wheel 129 on one side to rotate, which in turn drives the output conveyor belt 111 to move, which in turn drives the conveyor belt wheel 129 on the other side to rotate. The output conveyor belt 111 is supported and driven to move by the conveyor belt wheels 129 on both sides, which achieves the effect of moving the placed parts collection box 112.

[0025] Furthermore, a number of array support legs 106 are fixedly provided at the bottom of the annular base 101. The array support legs 106 are arranged in a circular array. A hydraulic lifting column 105 is fixedly connected to the bottom of the array support legs 106. A lifting base 103 is fixedly provided below the array support legs 106 on each side. The lifting base 103 is connected to the hydraulic lifting column 105 for lifting.

[0026] It should be further explained that the lifting base 103 is equipped with a hydraulic lifting system. When the lifting base 103 is started, it can drive the hydraulic lifting column 105 to move up and down, and then drive the array support leg 106 to move up and down through the lifting transmission of the hydraulic lifting column 105, and then drive the annular base 101 to move up and down through the support of the array support leg 106.

[0027] Furthermore, two vertical shock-absorbing support columns 140 are respectively provided on one side of the top of the conical sorting channel 124 and one side of the top of the channel support ring 125. The length of the shock-absorbing support column 140 at the top of the channel support ring 125 is longer than that of the shock-absorbing support column 140 at the top of the conical sorting channel 124. An inclined part guide slide 137 is installed on the top of each side of the shock-absorbing support column 140. Vertical slide fixing plates 135 are fixed on both sides of the part guide slide 137. The tail end of the part guide slide 137 is located above the arc-shaped guide channel 131. Two arc-shaped slide baffles 130 are fixed at the top of the conical sorting channel 124. The slide baffles 130 on both sides are symmetrically arranged. One end of the slide baffle 130 abuts against one end of the slide fixing plate 135.

[0028] It should be further explained that the shock-absorbing support column 140 is equipped with a shock-absorbing spring, which enhances the shock-absorbing support effect.

[0029] Furthermore, the parts storage compartment 120 is provided with an outward-facing lifting cavity 122, and the lifting cavity 122 is provided with a lifting plate 126 that can be lifted and moved. A hydraulic lifter 139 is fixedly provided at the bottom of the lifting cavity 122, and a lifting drive rod 138 that can be lifted and moved is provided in the hydraulic lifter 139. The top end of the lifting drive rod 138 is fixedly connected to the bottom of the lifting plate 126.

[0030] It is worth further explaining that the hydraulic lifter 139 is connected to the control terminal. When the hydraulic lifter 139 is started, it can drive the lifting drive rod 138 to move up and down, thereby driving the part lifting plate 126 to move up and down, and the part lifting plate 126 is tilted.

[0031] Furthermore, the parts storage compartment 120 is provided with two rotating plate supports 118 at one end, and the rotating plate supports 118 on both sides are symmetrically arranged. A release shaft 133 is rotatably provided between the rotating plate supports 118. A reset torsion spring 134 is installed and connected between the release shaft 133 and the rotating plate support 118. A parts release rotating plate 119 is fixedly connected to the outer end face of the release shaft 133.

[0032] It should be further explained that the different lifting cavities 122 are used to place and store various universal joint assembly parts. When the part lifting plate 126 moves upward, it can drive the height of the universal joint assembly parts to exceed the horizontal height of the part release plate 119. At this time, the universal joint assembly parts slide down along the part release plate 119 to the surface of the part guide slide 137, and move to the top of the conical sorting channel 124 through the inclined guide of the part guide slide 137, and fall down through the arc guide channel 131.

[0033] It is worth further explaining that during the process of the assembly parts falling through the guide slide 137, the shock-absorbing support column 140 provides a buffering support effect.

[0034] Furthermore, the annular base 101 is provided with an auxiliary material supply frame 113 on its side, and an auxiliary material supply frame 113 is provided with an auxiliary material beam 114 at the top of the auxiliary material supply frame 113. Several arrayed electromagnetic control valves 115 are fixedly provided at the top of the auxiliary material beam 114, and several support rods 127 are fixedly provided on the side of the auxiliary material beam 114. One end of the support rod 127 extends to the top of the part guide slide 137 and is connected to an auxiliary material storage tank 117.

[0035] It should be further explained that the auxiliary material storage tank 117 stores assembly materials such as gaskets of different specifications. The bottom of the drive gearbox 121 is equipped with a switch valve. The electromagnetic control valve 115 is connected to the auxiliary material storage tank 117 via data connection. The electromagnetic control valve 115 controls and drives the switch valve in the auxiliary material storage tank 117 to close and start.

[0036] It is worth further explaining that when the electromagnetic control valve 115 controls and drives the switch valve in the auxiliary material storage tank 117 to start, the gaskets and other universal joint assembly materials stored inside can fall down to the top of the parts guide slide 137, and guide the various materials to move into the arc-shaped guide channel 131, and then fall down into the parts collection box 112 for storage.

[0037] It is worth further explaining that when the annular rotating disk 102 is controlled to rotate in a certain direction, it can move different parts storage compartments 120 to one side of the parts guide slide 137. The parts release rotating plate 119 is equipped with a magnetic strip at the bottom of its tail end. When the corresponding parts storage compartment 120 moves above the parts guide slide 137, it is magnetically connected to the top of the parts guide slide 137 through the magnetic strip at the bottom of the tail end of the parts release rotating plate 119. At this time, the parts release rotating plate 119 is driven to rotate to an inclined position. When the parts release rotating plate 119 is driven to rotate away from the magnetic attraction of the parts guide slide 137, the release rotating shaft 133 connected to the parts storage compartment 120 is torn back to a horizontal state by the reset torsion spring 134.

[0038] The usage method of this solution is as follows: S1. Based on the current assembly requirements of the production line, the central control system sets the type and specification parameters of the required universal joint parts, such as gasket thickness and hole diameter. The operator fills the universal joint assembly parts of different specifications into the corresponding parts storage bins 120. The lifting cavity 122 of each storage bin holds one type of parts, while the auxiliary material storage tank 117 is filled with other auxiliary materials required for assembly, such as gaskets of specific specifications.

[0039] S2. After the equipment is started, the annular rotating disk 102 starts to rotate under the drive of the drive gearbox 121, so that the designated type of parts storage bin 120 rotates to the top of the parts guide slide 137. During this process, when the magnetic strip at the tail end of the part release plate 119 is magnetically attracted to the magnetic material at the top end of the part guide slide 137, the release plate 119 rotates downward to form an inclined outlet.

[0040] S3, the hydraulic lifter 139 is started, pushing the lifting drive rod 138 and the part lifting plate 126 to rise, pushing the part out of the lifting cavity 122; When the height of a part exceeds the part release turntable 119, the part slides down along the turntable, is guided by the part guide slide 137, and enters the arc-shaped guide channel 131 above the conical sorting channel 124. Because the arc-shaped guide channel 131 has a tapered structure that is wider at the top and narrower at the bottom, and the inner wall is a smooth arc-shaped surface, the parts can fall smoothly along it, effectively preventing jamming and stacking.

[0041] S3.1 When the assembly of a single universal joint assembly requires multiple different parts, the central control system, according to the preset program, instructs the gearbox 121 to work, driving the annular rotating disk 102 to perform intermittent indexing rotation. Each time the annular rotating disk 102 rotates by a predetermined angle, it precisely rotates and positions a parts storage bin 120 containing parts of the required specifications above the parts guide slide 137. When the magnetic strip at the tail end of the part release turntable 119 magnetically attracts the magnetic material at the top of the part guide slide 137, the release turntable 119 rotates downward to form an inclined outlet. Subsequently, the corresponding hydraulic lift 139 is activated, pushing the lifting drive rod 138 and the part lifting plate 126 upward to push the part out. The part slides down the turntable, is guided by the part guide slide 137, and enters the arc-shaped guide channel 131 above the conical sorting channel 124.

[0042] This process repeats until all the different parts required for the current allocation task have been output in sequence, at which point it stops.

[0043] S4. The electromagnetic control valve 115 opens the switch valve at the bottom of the corresponding auxiliary material storage tank 117 according to the control command, so that the required specifications of gaskets and other auxiliary materials fall into the parts guide slide 137, enter the arc guide channel 131 together with the main parts, and finally fall into the parts collection box 112 located on the output conveyor belt 111.

[0044] S5. After the parts collection box 112 at the receiving station receives a complete set of parts, the central control system will issue a command to start the conveyor motor 132, which will drive the output conveyor belt 111 to move forward through the conveyor belt roller 128 and the conveyor belt wheel 129, and output to connect with the subsequent assembly workshop.

[0045] S6. If it is necessary to adjust the height of the equipment to adapt to different production line interfaces, the hydraulic lifting column 105 can be raised and lowered through the hydraulic lifting system in the lifting base 103, thereby driving the entire annular base 101 and its structure to adjust the height.

[0046] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
