Description

Technical Field

[0001] This invention relates to the field of automated assembly technology for power tools, and more particularly to an assembly system for a spindle and dust seal. Background Technology

[0002] Handheld power tools are machines that perform mechanical functions by being driven by an electric motor or electromagnet. They can be categorized by use into: metal cutting, abrasive, and assembly tools. Angle grinders, as a type of abrasive tool, are also known as grinding machines or disc grinders and are mainly used for cutting, grinding, and brushing metals and stone.

[0003] The main components of an angle grinder include: spindle, dust seal, head housing, machine housing, stator, rotor, transmission gears, controller, and shaft. Given the large variety of components and the complex connections between them, there is currently no fully automated assembly line for angle grinders in the industry. The common method to improve assembly efficiency is to use a semi-automatic, semi-manual assembly process.

[0004] The spindle, a commonly used component in angle grinders, is cylindrical in shape. Before assembling the angle grinder, a dust seal ring is often fitted onto it to provide dust protection during later use. Normally, the dust seal ring and spindle are interference-fitted, requiring a certain amount of pressure to be applied during assembly.

[0005] Due to its unique structure and assembly method, angle grinders have lacked suitable assembly equipment in current automated assembly processes. A common approach is to manually pick up materials and assemble them, which is not only labor-intensive and results in a low yield rate but also extremely inefficient. Alternatively, a production line can be used for material handling, followed by manual picking and placement of materials under designated pressing fixtures. After pressing, the materials are collected, and the process is repeated.

[0006] It can be seen that the above-mentioned traditional solutions cannot achieve fully automated feeding, pressing and unloading of dust seals and spindles, which will seriously restrict the efficiency of angle grinder assembly and increase the manufacturer's costs.

[0007] Therefore, a new technical solution is urgently needed to solve the above-mentioned technical problems. Summary of the Invention

[0008] The purpose of this invention is to overcome the problems of the prior art and provide a spindle and dust seal assembly system that can effectively solve the technical problems of slow material feeding, low pressing qualification rate and time-consuming material removal in the prior art when assembling dust seals and spindles by manual or semi-manual means, and the safety hazards in the pressing process due to manual operation.

[0009] The above objectives are achieved through the following technical solutions:

[0015] Furthermore, the piston of the main shaft pressing cylinder is connected to the main shaft pressing rod through a main shaft coupling. The main shaft coupling is connected to the main shaft support plate. The main shaft support plate is movably connected to the upright of the main shaft pressing bracket and can slide up and down relative to the upright.

[0016] Furthermore, the spindle feeding mechanism includes a material box connected to the worktable, a material transfer module is arranged along the outer side of the material box's outlet, and a feeding module is arranged along the inner side of the material box's outlet.

[0017] The feeding module includes a cylinder, and the piston end of the cylinder is connected to a lifting plate connecting seat. A first lifting plate and a second lifting plate are vertically arranged on the lifting plate connecting seat and are parallel to each other.

[0018] The material box's outlet is provided with a first baffle plate and a second baffle plate that are parallel to each other. The first baffle plate and the second baffle plate respectively form a first through groove and a second through groove with the material box, through which the first lifting plate and the second lifting plate can enter the material box. The second baffle plate serves as one side of the material box and forms a U-shaped outlet with the material box.

[0019] The material transfer module includes a material transfer track disposed on the outer side of the second baffle plate, and a material pushing device that can push the main shaft entering the material transfer track.

[0020] The material transfer track includes a first track side plate connected to the second baffle plate and a second track side plate parallel to the first track side plate. The second track side plate and the first track side plate form a hollow track groove that can clamp the main shaft. The main shaft can be vertically arranged in the track groove. The top of the first baffle plate is flush with the top of the second baffle plate. A baffle block is provided at one end of the track groove to position the main shaft during transmission, facilitating clamping by the material transfer mechanism.

[0022] Furthermore, the pushing device includes a base plate vertically connected to the bottom of the second baffle plate, and symmetrical lead screw support blocks are provided between the second baffle plate and the base plate for movably clamping both ends of the lead screw. Either end of the lead screw is connected to a lead screw motor. A matching lead screw slider is sleeved on the lead screw, and a pushing block is connected to the lead screw slider.

[0023] A pusher block slide rail is provided on the outer side of the top of the second baffle plate. The thickness of the pusher block slide rail is less than the thickness of the second baffle plate. The pusher block slide rail matches the pusher block groove provided on the bottom side of the pusher block.

[0024] Furthermore, the material transfer mechanism includes a material transfer base plate fixedly connected to the surface of the worktable. A pair of symmetrical material transfer supports are provided on the material transfer base plate. A material transfer crossbeam is provided on each of the material transfer supports. A material transfer translation device is provided on the material transfer crossbeam. The material transfer translation device includes a material transfer slide rail and a matching material transfer slide block on the material transfer crossbeam. The side of the material transfer slide block is connected to the piston end of an electric linear push rod provided on the material transfer crossbeam. The electric linear push rod can drive the material transfer slide block to slide linearly along the material transfer slide rail. A material transfer lifting cylinder is also provided on the material transfer slide block, which can drive a cylinder gripper to move vertically.

[0026] This invention provides a spindle and dust ring assembly system. It employs a separate feeding method to load components of different shapes or categories to designated pressing positions. Specifically, a lifting spindle feeding mechanism moves irregularly stored spindles in a material box onto a transfer track, where they are systematically stacked. A pushing device then horizontally pushes the spindles arranged on the transfer track to achieve the feeding purpose. Simultaneously, workpiece position correction is performed, enabling more efficient pressing. After pressing, the completed assembly can be quickly removed, allowing for secondary assembly. This device is not only simple in structure and highly automated, but also enables fully unattended continuous operation while ensuring a sufficient supply of parts to be assembled. This reduces enterprise production costs and improves the efficiency of angle grinder processing. Attached Figure Description

[0051] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. The described embodiments are merely some, not all, of the embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0052] like Figure 1 and 2As shown, a spindle and dust ring assembly system includes a worktable 1. A spindle assembly seat 2 for mounting a spindle 9 is provided on the surface of the worktable 1. A spindle pressing mechanism 3 is provided directly above the spindle assembly seat 2. A dust ring feeding mechanism 4 and a spindle feeding mechanism 5 are provided on the surface of the worktable 1 along the periphery of the spindle assembly seat 2. The dust ring feeding mechanism 5 can transmit dust rings 10 into the spindle assembly seat 2. The spindle feeding mechanism 5 can automatically stack the spindle 9 for transfer mechanism 6 to move to the spindle assembly seat 2. The transfer mechanism 6 can remove the assembled spindle 9 onto a spindle carrier 7. The spindle carrier 7 matches a conveyor belt 8 provided on the side of the worktable 1.

[0053] Specifically, this system is mainly used for the insertion of dust rings 10 and spindle 9 in an angle grinder. The dust rings 10 are stored and fed by the dust ring feeding mechanism 5, and the spindle 9 is stored and stacked by the spindle feeding mechanism 5. Since the dust rings 10 are all circular, they can be directly transferred to the spindle assembly seat 2. However, since the spindle 9 is cylindrical and has different annular grooves, it is not convenient to directly feed it to the spindle assembly seat 2. Instead, the disordered bulk spindle 9 needs to be stacked first, and then transferred one by one to the spindle assembly seat 2 by the material transfer mechanism 6. The pre-placed dust rings 10 are inserted, and finally, the spindle pressing mechanism 3 at the top of the spindle assembly seat 2 applies downward pressure to achieve the pressing between the spindle 9 and the dust rings 10. The assembled spindle 9 is then removed by the material transfer mechanism 6.

[0054] In this embodiment, the assembled spindle 9 is moved onto the spindle carrier 7 and collected via the conveyor belt 8.

[0055] It should be noted that all the electronic control components involved in this system are controlled by the electronic control system 12, which is installed on the enclosure 11. In this embodiment, the enclosure 11 can be understood as a protective cover with a cabinet door.

[0056] The status detection of each functional component in this system is obtained by installing sensors in different locations so that the electronic control system 12 can coordinate and control the system, thereby achieving automated operation.

[0057] like Figure 2 and 4 As shown, in this embodiment, the spindle mounting base 2 includes a spindle base 21 that is vertically connected to the worktable 1, and a spindle sleeve 22 that can be sleeved on the spindle 9 is connected to the spindle base 21.

[0058] A dustproof ring inlet 23 is provided on the side of the top port of the main shaft sleeve 22, allowing the dustproof ring 10 to enter. The dustproof ring inlet 23 is connected to the dustproof ring feeding mechanism 4.

[0059] The dustproof ring feeding mechanism 4 includes a vibratory feeder 41 connected to the workbench 1, and the dustproof ring 10 is stored in the vibratory feeder 41. The vibratory feeder 41 is connected to the dustproof ring inlet 23 through the dustproof ring conveying track 42. A linear feeder 43 is connected to the lower side of the dustproof ring inlet 23 and is connected to the workbench 1.

[0060] In this embodiment, the vibratory feeder 41 is an auxiliary feeding device for automatic assembly or automatic processing machinery, referred to as a parts feeding device. The working principle of the vibratory feeder is: frequency converter and motor achieve automatic conveying.

[0061] The linear feeder, also known as a linear vibratory feeder or a horizontal feeder, is an auxiliary device of an electromagnetic vibratory feeding system. It can be synchronized with the main vibratory feeder for feeding. The linear feeder is an automatic directional and sorting feeding device. Its purpose is to automatically and orderly arrange the vibrating workpieces neatly and accurately and transport them to the next process. Inside the linear feeder is a pulse electromagnet that causes the feed channel to vibrate vertically. Due to the inclination of the spring plates, the hopper oscillates around its vertical axis until it reaches the discharge port.

[0062] like Figure 3 and 4 As shown, in order to ensure that the dustproof ring 10 can be accurately transmitted into the vibratory plate 41 along the dustproof ring conveying track 42, this embodiment also provides a right-angle reversing track 44 between the discharge end of the dustproof ring conveying track 42 and the dustproof ring inlet 23. A reversing push rod 45 is provided on the side of the right-angle reversing track 44. The reversing push rod 45 is connected to the piston of the reversing cylinder 46. When the dustproof ring 10, which is linearly transmitted on the dustproof ring conveying track 42, is then conveyed to the right-angle reversing track 44, it is pushed by the reversing push rod 45 to the dustproof ring locking position provided at the port of the main shaft sleeve 22 for the main shaft 9 to insert.

[0063] like Figure 2 As shown, the spindle pressing mechanism 3 in this embodiment includes a spindle pressing bracket 31 that is vertically connected to the worktable 1. A spindle pressing cylinder 32 is provided on the top of the spindle pressing bracket 31. The piston end of the spindle pressing cylinder 32 is connected to a spindle pressing rod 33 that matches the end of the spindle. The spindle pressing cylinder 32 can drive the spindle pressing rod 33 to move vertically up and down along the spindle bracket 31.

[0064] The piston of the main shaft pressing cylinder 32 is connected to the main shaft pressing rod 33 through the main shaft coupling 34. The main shaft coupling 34 is connected to the main shaft support plate 35. The main shaft support plate 35 is movably connected to the upright rod 36 of the main shaft pressing bracket 31 and can slide up and down relative to the upright rod 36.

[0065] like Figures 5-11 As shown, in this embodiment, the spindle feeding mechanism includes a material box 51 connected to the worktable 1. A material transfer module 52 is provided on the outer side of the material box 51's discharge port, and a feeding module 53 is provided on the inner side of the material box 51's discharge port. The feeding module 53 lifts the scattered spindles 9 stored in the material box 51 and drops them into the material transfer module 52.

[0066] Working principle:

[0067] The feeding module 53 lifts the main shaft 9, which does not need to be stacked, from the material box 51 and lowers it into the material transfer module 52, thereby arranging and stacking the main shaft 9.

[0068] Specifically, the feeding module 53 includes a cylinder 518, the piston end of which is connected to a lifting plate connecting seat 519, and a first lifting plate 520 and a second lifting plate 521 that are parallel to each other are vertically arranged on the lifting plate connecting seat 519.

[0069] In this embodiment, the discharge port of the material box 51 is provided with a first baffle plate 54 and a second baffle plate 55 that are parallel to each other. The first baffle plate 54 and the second baffle plate 55 respectively form a first through groove 56 and a second through groove 57 through which the first lifting plate 520 and the second lifting plate 521 can pass. The first lifting plate 520 and the second lifting plate 521 can enter the material box 51 through the first through groove 56 and the second through groove 57. The second baffle plate 55 serves as a side of the material box 51 and forms a U-shaped discharge port 58 with the material box 51.

[0070] The material transfer module 52 includes a material transfer track 516 disposed on the outer side of the second baffle plate 55, and a material pushing device 517 that can push the main shaft 9 that enters the material transfer track 516.

[0071] The material transfer track 516 includes a first track side plate 59 connected to the second baffle plate 55 and a second track side plate 510 parallel to the first track side plate 59. The second track side plate 510 and the first track side plate 59 form a hollow track groove 511 that can clamp the main shaft 9. The main shaft 9 can be vertically arranged in the track groove 511.

[0072] Specifically, due to the special cross-shaped structure of the main shaft 9, the top of the first baffle plate 54 needs to be flush with the top of the second baffle plate 55 in order to provide a horizontal conveying surface for the main shaft 9.

[0073] like Figures 5-8 As shown, as an optimization of this embodiment, the top end of the first baffle plate 54 is flush with the top end of the second baffle plate 55;

[0074] A stop block 512 is provided at one end of the track groove 511 to position the main shaft 9 during transmission, so as to facilitate the material transfer mechanism 6 to clamp it.

[0075] An inclined bottom plate 513 is provided in the material box 51, which can slide the main shaft 9 into the first through groove 56.

[0076] like Figures 5-11 As shown, in order to facilitate the guidance of the main shaft 9 in the material box 51 to the material transfer track 516, this embodiment has a guide inclined edge 514 with the same inclination angle and the same orientation on the top of the first lifting plate 520, the second lifting plate 521, the first baffle plate 54 and the second baffle plate 55.

[0077] The inclined angle of the guide bevel 514 is 30° to 60°.

[0078] To prevent blockage due to an excessive number of spindles 9 during the material guiding process, this embodiment also provides several material leakage slots 515 on the top of the first lifting plate 520, which are opposite to the material guiding inclined edge 514. These are used to guide any unguided spindles 9 into the material box 51.

[0079] like Figure 5 As shown, the pushing device 517 in this embodiment includes a base plate 522 vertically connected to the bottom of the second baffle plate 55. Symmetrical lead screw support blocks 523 are provided between the second baffle plate 55 and the base plate 522 for movably clamping both ends of the lead screw 524. Either end of the lead screw 524 is connected to the lead screw motor 525. A matching lead screw slider 526 is sleeved on the lead screw 524. A pushing block 527 is connected to the lead screw slider 526. The pushing block 527 is used to push the main shaft 9 that enters the track groove 511.

[0080] To facilitate the smooth movement of the pusher block 527 above the track groove 511, this embodiment provides a pusher block slide rail 528 on the outer side of the top of the second baffle plate 55. The thickness of the pusher block slide rail 528 is less than the thickness of the second baffle plate 55. The pusher block slide rail 528 matches the pusher block groove 529 located on the bottom side of the pusher block 527. Driven by the lead screw motor 525, the pusher block 527 can directly act on the side of the main shaft 9 to achieve horizontal linear movement.

[0081] Working principle:

[0082] like Figure 9 and 10 As shown, when the cylinder 518 is in the retracted state, the first lifting plate 520 and the second lifting plate 521 are at the lowest position in the material box 51 (which can also be understood as being at the lowest position of the first through groove 56 and the second through groove 57). The numerous main shafts 9 in the material box 51 will slide down along the inclined bottom plate 513 and accumulate at the opening of the first through groove 56 due to their own gravity.

[0083] At this time, the top of the first lifting plate 520 does not extend out of the first through groove 56; when the cylinder 518 extends for the first time, the first lifting plate 520 and the second lifting plate 521 move upward along the first through groove 56 and the second through groove 57, and lift the main shaft 9 located at the first through groove 56 to the top of the first baffle plate 54. Then, the cylinder 518 moves backward, and the main shaft 9, which has been lifted to the top of the first baffle plate 54, falls to the top of the second lifting plate 521. Then, the cylinder 518 moves upward, and the main shaft 9, which has been lifted to the top of the second lifting plate 521, flips over the second baffle plate 55 and falls into the track groove 511.

[0084] By controlling the continuous extension and retraction of the cylinder 518, the main shaft 9 in the material box 51 is continuously lifted into the track groove 511 to complete the feeding purpose; when the main shaft 9 in the track groove 511 reaches a predetermined number, the pushing device 517 is controlled by the external central control system to push the multiple main shafts 9 arranged in the track groove 511 to the upper feeding end so that the cylinder gripper 68 on the material transfer mechanism 6 can clamp them.

[0085] like Figure 2 and 3As shown, the material transfer mechanism 6 includes a material transfer base plate 61 fixedly connected to the surface of the worktable 1. A pair of symmetrical material transfer supports 62 are provided on the material transfer base plate 61. A material transfer crossbeam 63 is provided on the material transfer support 62. A material transfer translation device 64 is provided on the material transfer crossbeam 63. The material transfer translation device 64 includes a material transfer slide rail 65 provided on the material transfer crossbeam 63 and a matching material transfer slide block 66. The side of the material transfer slide block 66 is connected to the piston end of an electric linear push rod 67 provided on the material transfer crossbeam 63.

[0086] The electric linear push rod 67 can drive the material transfer slide 66 to slide linearly along the material transfer slide rail 65; the material transfer slide 66 is also provided with a material transfer lifting cylinder 69 that can drive the cylinder gripper 68 to move vertically up and down, the piston end of the material transfer lifting cylinder 69 is connected to a cylinder connecting seat 610, and the bottom side of the cylinder connecting seat 610 is connected to the cylinder gripper 68.

[0087] like Figure 2 and 3 As shown in the figure, in order to realize material picking (picking up material from the spindle loading mechanism 5) and material transfer (moving the assembled spindle 9 from the spindle mounting seat 2 to the spindle carrier 7), there are two cylinder grippers 68, including a first cylinder gripper 611 and a second cylinder gripper 612. Correspondingly, there are two material transfer lifting cylinders 69, including a first material transfer lifting cylinder 613 and a second material transfer lifting cylinder 614.

[0088] The first cylinder gripper 611 is connected to the first material transfer lifting cylinder 613, and the second cylinder gripper 612 is connected to the second material transfer lifting cylinder 614. The first material transfer lifting cylinder 613 and the second material transfer lifting cylinder 614 are symmetrically arranged on the material transfer slide 66.

[0089] To ensure coordinated operation, the distance between the first cylinder gripper 611 and the second cylinder gripper 612 is equal to the distance between the stop blocks 512 of the track groove 511 of the main shaft feeding mechanism 6 and the main shaft mounting base 2, and equal to the distance between the main shaft mounting base 2 and the main shaft carrier 7.

[0090] The above description is merely illustrative of the embodiments of the present invention and is not intended to limit the present invention. For those skilled in the art, any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
