Description

Technical Field

[0001] The invention relates to bicycle production technology, and in particular to a fully automatic bicycle production device. Background Art

[0002] As a common means of transportation, the structure of a bicycle is relatively simple, mainly including a frame, wheels, transmission system, braking system, steering system and seat. Among them, the wheel is an important component of the bicycle, which can support the bicycle body, buffer external impact, achieve contact with the road surface and ensure the driving performance of the bicycle. The wheel mainly includes a hub, spokes and a hub.

[0003] For example, the patent with the authorization announcement number CN117862870B and the authorization announcement date May 28, 2024, is named a bicycle assembly production line, including an assembly base, two arc-shaped slide rails are arranged on the top of the assembly base, and the two arc-shaped slide rails are fixedly connected to a first connecting frame on the side away from each other, and the first connecting frame is fixedly connected to the top of the assembly base, and a plurality of connecting plates are circumferentially arranged between the two arc-shaped slide rails, and the two ends of the connecting plates are fixedly connected to a slide seat; the present invention uses the action of a synchronous assembly mechanism to synchronously assemble the center shaft and the center sleeve, and uses an arc groove and two clamping rings to limit and clamp the bicycle hub, so that the upper bearing, the lower bearing, the center sleeve and the center shaft can be assembled and installed through two assembly steps, reducing the assembly steps and the time for the bicycle hub to move and stay, and effectively improving the assembly efficiency of the bicycle hub.

[0033] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0034] like Figure 1-10 As shown, an embodiment of the present invention provides a fully automatic bicycle production device, including a plate chain conveyor belt 1, on which a plurality of mounting bases 15 for mounting a hub are rotatably mounted, and also includes a spoke output mechanism 3 and an intermittent drive mechanism 4, wherein the intermittent drive mechanism 4 is used to intermittently drive the mounting base 15 to rotate; when the mounting base 15 stops rotating, the spoke output mechanism 3 outputs the spokes and inserts them into the holes on the hub.

[0035] Specifically in the present embodiment, the plate chain conveyor belt 1 is composed of a plurality of plates connected end to end, and certain activities can be performed between the plates. The plate chain conveyor belt 1 is an annular structure when working, and it itself performs intermittent movement, cooperating with the spoke output mechanism 3 and the intermittent drive mechanism 4. It is mainly used for intermittent conveying of the mounting base 15 and the hub. When the plate chain conveyor belt 1 is stationary, the spokes are installed on the hub through the spoke output mechanism 3 and the intermittent drive mechanism 4. The plate chain conveyor belt 1 is commonly used as a conveying structure in the prior art, and will not be described in detail; the mounting base 15 is a circular block structure, and a clamping groove is provided at one end away from the plate chain conveyor belt 1, and the clamping groove is used The hub is used for clamping and installation. After clamping, the hub cannot move on the mounting base 15. Of course, the hub is installed on the mounting base 15 by a manipulator or other mechanical equipment when the clamping groove is facing upward. When the hub is in the initial state, one of the holes corresponds to the output position of the spoke output mechanism 3; the spoke output mechanism 3 is arranged obliquely, because the holes on the hub are also arranged obliquely, and the spoke conveying mechanism is used to output the spokes one by one. A plurality of spokes are arranged vertically in the spoke conveying mechanism in sequence for easy output one by one. The spoke output mechanism 3 also outputs spokes intermittently and cooperates with the intermittent driving mechanism 4; the intermittent driving mechanism 4 is used to When the plate chain conveyor belt 1 stops moving, it intermittently drives the mounting base 15 and the hub to rotate intermittently. When the hub is stationary, the spokes are output through the spoke output mechanism 3 and inserted into the holes on the hub. Specifically, in a complete spoke installation process, it includes a hub conveying stroke, a first spoke installation stroke and a second spoke installation stroke. The hub conveying stroke: when the plate chain conveyor belt 1 is stationary, the hub is installed on the mounting base 15 and one of the holes is aligned with the output position of the spoke output mechanism 3. After the hub is installed, the plate chain conveyor belt 1 moves and drives the hub to move to the bottom of the spoke output mechanism 3 and remains stationary. The first spoke installation stroke: when the hub is stationary After stopping, a spoke is outputted through the spoke output mechanism 3 and directly inserted into the hole on the hub; second spoke installation stroke: after the first spoke installation stroke is completed, the hub is driven by the intermittent drive mechanism 4 to rotate a specific angle (the angle is determined according to the number of holes on the hub) and then remains stationary. At this time, the new hole on the hub corresponds to the output position of the spoke, and then a spoke is outputted through the spoke output mechanism 3 and inserted into the new hole, and then the second spoke installation stroke is repeated until multiple spokes are fully installed; in this way, the installation efficiency of the spokes is improved. In addition, the entire spoke installation process is an assembly line operation, which can be adapted to the entire bicycle installation production process.

[0036] In another embodiment provided by the present invention, it also includes a fixed seat 2, two support frames 11 are installed on the fixed seat 2, and a drive roller 12 is rotatably installed on the upper end of the support frame 11. The plate chain conveyor belt 1 is connected between the two drive rollers 12. In addition, it also includes a power source for driving the drive roller 12 to rotate, such as a drive motor (not shown in the figure), and the drive roller 12 is controlled to rotate and stop by starting and stopping the drive motor, thereby intermittently driving the plate chain conveyor belt 1 to move.

[0037] In another embodiment provided by the present invention, the mounting bases 15 are arranged at intervals on the plate chain conveyor belt 1. Preferably, a mounting base 15 is installed between every two plates.

[0038] In another embodiment provided by the present invention, the mounting base 15 is rotatably mounted on the plate chain conveyor belt 1 via a rotating shaft 151, and the lower end of the rotating shaft 151 passes through the plate chain conveyor belt 1 and extends to the bottom of the plate chain conveyor belt 1. The rotating shaft 151 provides an installation position for the mounting base 15 and can drive the mounting base 15 to rotate by driving the rotating shaft 151 to rotate.

[0039] In another embodiment provided by the present invention, the spoke output mechanism 3 includes a first bracket 31 fixed to the upper end of the fixing seat 2, and a receiving frame 32 for receiving the spokes is installed on the upper end of the first bracket 31. The receiving frame 32 is arranged obliquely, so that the spokes are conveniently output from the receiving frame 32 under the action of their own gravity. Preferably, the inclination angle of the receiving frame 32 is consistent with the inclination angle of the hole, so that the hole on the hub coincides with the output path of the spoke, and a receiving groove is provided in the receiving frame 32, and the width of the receiving groove is equal to the diameter of the spoke, so that multiple spokes can be arranged vertically in the receiving groove, and the bottom of the receiving frame 32 is close to the plate chain transmission A discharge port is provided at one end of the conveyor belt 1, and a discharge assembly (not shown in the figure) is also installed on the accommodating frame 32. The discharge assembly is used to discharge the spokes one by one. In the prior art, there are a variety of schemes that can realize the function of the discharge assembly. Preferably, the discharge assembly is connected by an electric telescopic rod and a blocking block, and the blocking block is used to block the spoke at the bottom (that is, to close the discharge port). When the spoke needs to be output, the blocking block is pulled outward by the electric telescopic rod. At this time, the lowest spoke will slide downward under the action of its own gravity and output from the accommodating frame 32. After a spoke is output, the upper spoke also moves downward as a whole, and the blocking block is pushed by the electric telescopic rod to continue to block the discharge port.

[0040] In another embodiment provided by the present invention, a second bracket 14 is further fixedly connected to the fixed seat 2, and the second bracket 14 is used to install the intermittent drive mechanism 4; the intermittent drive mechanism 4 includes a driving gear 48 fixedly arranged at the lower end of the rotating shaft 151, and an electric push rod 49 is installed at the upper end of the second bracket 14. A moving rod 50 is fixedly connected to the movable part of the electric push rod 49, and a plurality of racks 51 are arranged at intervals on the moving rod 50, and the gaps between the racks 51 are defined as static gaps. The plurality of gear sets are preferably arranged at even intervals, and the racks 51 and the driving gear 48 are arranged in a corresponding matching manner, and the racks 51 and the driving gear 48 are meshed with each other. Each rack 51 can allow the driving gear 48 to rotate a specific angle; during the second spoke installation stroke, after the previous spoke is installed, the electric push rod 49 pushes the moving rod 50 to continue to move in the direction close to the driving gear 48, so that the rack 51 contacts the driving gear 48 and drives the driving gear 48 and the rotating shaft 151 to rotate, and the moving rod 50 continues to move, so that the driving gear 48 is located in the static gap. At this time, the driving gear 48 remains stationary. In this way, the electric push rod 49 continuously and steadily pushes the moving rod 50 to move, so that the driving gear 48 can be intermittently rotated and the spokes can be installed into the hub when the driving gear 48 is stationary.

[0041] In another embodiment provided by the present invention, the intermittent drive mechanism 4 includes a driving protrusion 41 fixed at the bottom of the rotating shaft 151, and a first connecting portion 42 is slidably installed on the upper end of the second bracket 14. There is a certain distance between the driving protrusion 41 and the end of the first connecting portion 42 close to the driving protrusion 41. A plurality of friction plates 43 are installed at intervals on the end of the first connecting portion 42 close to the driving protrusion 41. The friction plates 43 have a certain thickness so that they can contact the driving protrusion 41. The gap between the two friction plates 43 is defined as a non-contact gap. The friction plates 43 and the driving protrusion 41 are correspondingly arranged. When the friction plates 43 contact the driving protrusion 41, the driving protrusion 41 can be driven to rotate by friction. In addition, a power source such as a hydraulic rod (not shown in the figure) that can drive the first connecting portion 42 to move is also included, which will not be described in detail; the driving protrusion 41 includes a cylindrical portion 411, and the cylindrical portion 411 is used to connect The friction plate 43 is driven to collect and rotate intermittently. Preferably, the height of the first connecting part 42 is consistent with the height of the cylindrical part 411, so that the first connecting part 42 is in full contact with the cylindrical part 411; specifically, after the previous spoke is installed, the first connecting part 42 is pushed by the hydraulic rod to continuously move in the direction close to the driving protrusion 41, so that the friction plate 43 is in contact with the outer wall of the cylindrical part 411 and drives the rotating shaft 151 to rotate, and the moving rod 50 continues to move, so that the driving boss is located in the non-contact gap. At this time, the driving boss remains stationary, and then the spokes are output to the holes on the hub through the spoke output mechanism 3. In this way, the first connecting part 42 is continuously and stably pushed by the hydraulic rod to move, so that the driving boss and the hub can be rotated intermittently and the spokes can be installed into the hub when the hub is stationary. Through the above technical solution, the intermittent driving mechanism 4 and the spoke output mechanism 3 can cooperate with each other to stably output a single spoke to the hole on the hub.

[0042] In another embodiment of the present invention, an annular through groove 13 is provided in the middle of the arc-shaped side wall of the driving roller 12. The annular through groove 13 has a certain thickness. This design is to facilitate the passage of the driving gear 48 or the driving protrusion 41.

[0043] Furthermore, since the spokes themselves have a small diameter and the holes on the hub that match them are also small, in actual operation, the spokes need to slide downward under their own gravity and be inserted into the holes with high precision, which places high demands on the movement accuracy of the intermittent drive mechanism 4. Moreover, even if the holes on the hub are on the output path of the spokes, the spokes may get stuck in the holes. For this reason, the present embodiment provides a further solution; a truncated cone portion 412 is formed at one end of the cylindrical portion 411 away from the rotating shaft 151, and the truncated cone portion 412 is a truncated cone-shaped block structure, and the diameter of the truncated cone portion 412 on the side close to the cylindrical portion 411 is larger than the diameter of the truncated cone portion 412. The diameter of the part 412 away from the cylindrical part 411, and also includes a second connecting part 44, a side rod 45 is connected between the end of the second connecting part 44 away from the driving protrusion 41 and the first connecting part 42, the second connecting part 44 and the first connecting part 42 are arranged opposite to each other, and the lengths of the two are the same, and there is also a certain distance between the end of the second connecting part 44 close to the driving protrusion 41 and the driving protrusion 41. Different from the above embodiment, in this embodiment, the movable end of the hydraulic rod is connected to the side rod 45, and the hydraulic rod controls the movement of the side rod 45 to control the synchronous movement of the first connecting part 42 and the second connecting part 44. The non-contact gap on the first connecting part 42 A first reciprocating assembly 46 is installed inside, and the first reciprocating assembly 46 includes a plurality of first contact rods 461 evenly spaced and fixed on the first connecting portion 42. The first contact rod 461 is an L-shaped structure and is connected by a horizontal section and a vertical section. The vertical section is fixed to the first connecting portion 42, and the horizontal section is located below the first connecting portion 42. One end of the horizontal section close to the driving protrusion 41 is an inclined surface. Preferably, the inclination angle of the inclined surface is consistent with the inclination angle of the side wall of the truncated cone portion 412, so as to make the first contact rod 461 fully contact with the side wall of the truncated cone portion 412. In addition, second reciprocating assemblies 47 are also installed at intervals on the second connecting portion 44. The second reciprocating assembly 47 is arranged corresponding to the first reciprocating assembly 46, and the second reciprocating assembly 47 also includes a plurality of second contact rods 471 evenly spaced and fixed on the second connecting portion 44. The second contact rods 471 have the same shape and size as the first contact rods 461. The difference is that the first contact rods 461 and the second contact rods 471 (in the horizontal direction) are arranged alternately, and the first contact rods 461 and the second contact rods 471 and the truncated cone portion 412 are arranged correspondingly, but the first contact rods 461 and the second contact rods 471 will not contact the truncated cone portion 412 at the same time. In addition, preferably, the number of the first contact rods 461 and the second contact rods 471 are both seven.

[0044] During the continuous synchronous movement of the first connecting portion 42 and the second connecting portion 44, the movement of the mounting base 15 is divided into two strokes, and the two strokes are performed alternately in sequence, namely, the shifting stroke and the auxiliary feeding stroke. When the first spoke is installed, the hydraulic rod is started and the shifting stroke is immediately entered. During the shifting stroke, the friction plate 43 contacts the outer wall of the cylindrical portion 411 and drives the rotating shaft 151 to rotate, so that the mounting base 15 rotates a certain angle. At this time, the hub also rotates a certain angle and makes the new hole correspond to the spoke output mechanism 3. In this process, although the second connecting portion 44 moves synchronously, the second connecting portion 44 does not If there is no contact with the cylindrical part 411, the movement of the mounting base 15 will not be affected. At this time, a spoke is output through the spoke output mechanism 3. If the spoke is inserted into the hole on the hub, the installation is completed. If the spoke is not inserted into the hole on the hub, it will rest against the inner wall of the upper end of the hub. The first connecting part 42 continues to move, thereby entering the auxiliary feeding stroke. At this time, the friction plate 43 is separated from the cylindrical part 411, and the end of the horizontal section of the first contact rod 461 contacts the outer wall of the upper end of the conical part 412 and then pushes the conical part 412 to rotate slightly (this rotation is defined as the positive direction). The first connecting part 42 continues to move, thereby A contact rod 461 is separated from the conical portion 412. At this time, the second contact rod 471 contacts the outer side wall of the conical portion 412 and then pushes the conical portion 412 to rotate slightly (the rotation is defined as reverse). In this way, during the continuous movement of the first connecting portion 42, the conical portion 412 and the mounting base 15 are driven to continuously rotate in the positive and reverse directions with a small amplitude, that is, the mounting base 15 is rotated and shaken continuously, so that the spokes resting on the inner side wall of the upper end of the hub contact with the holes and are inserted into the holes under the action of their own gravity. Through the above technical scheme, the spokes are installed one by one through the displacement stroke, and the installation is achieved through the auxiliary feeding stroke. After rotating a specific angle, the base 15 can shake to a certain extent to facilitate the installation of the spokes. In addition, the auxiliary feeding stroke actually has two functions. First, in the actual working process, even if the position of the installation base 15 or the position of the hub is slightly offset, it will not affect the insertion of the spokes into the holes of the hub, and there is no need to make high requirements on the movement accuracy of the intermittent drive mechanism 4. In addition, it also avoids the situation where the spokes are stuck in the hole. In addition, secondly, after the spokes are inserted into the holes, continuous shaking can make the spokes continue to slide in the holes until their ends are stuck in the holes, thereby preventing the spokes from being unable to continue to slide down to the installation position under the action of their own gravity.

[0045] Furthermore, the continuous small-amplitude shaking of the mounting base 15 causes the hub to shake slightly, which has two functions. The two functions also correspond to two working processes, namely, the feeding process and the installation process of the spokes. The feeding process is to insert the spokes into the holes, and the installation process is to make the spokes swing slightly after entering the holes so as to continuously move to the installation position. However, obviously, during the feeding process, the swinging speed of the mounting base 15 should not be too large, in order to ensure that the spokes can be stably inserted into the holes, and the swinging amplitude during the installation process should not be too small, in order to ensure that the spokes will not be stuck. For this reason, the present embodiment provides a further solution, so that the shaking speed of the mounting base 15 can be small at first and then large, so as to cooperate with the above-mentioned two working strokes; the first A plurality of first driving rods 462 are evenly spaced in the reciprocating assembly 46, and the first driving rods 462 are also L-shaped structures. The number of the first driving rods 462 is preferably three. In this embodiment, the number of the first contact rods 461 is preferably four. The size of the first driving rod 462 is larger than the first contact rod 461. The first driving rod 462 is composed of a first section and a second section. The first section is in a vertical state, and the second section is in a horizontal state. The vertical height of the second section is less than the vertical height of the vertical section of the first contact rod 461, and the length of the second section is also longer than the length of the horizontal section of the first contact rod 461. The first driving rod 462 is corresponding to the side wall of the truncated cone portion 412 away from the mounting base 15, and the first driving rod 462 is driven at the first connecting portion 42. 62 moves, the second section of the first driving rod 462 will contact the side wall of the truncated cone portion 412. In addition, a plurality of second driving rods 472 are evenly spaced in the second reciprocating assembly 47. The first driving rod 462 and the second driving rod 472 have the same size and shape. The difference is that the first driving rod 462 and the second driving rod 472 are arranged alternately, and the two will not contact the truncated cone portion 412 at the same time; during the auxiliary feeding stroke, the hydraulic cylinder maintains a stable moving speed. At this time, the first connecting portion 42 and the second connecting portion 44 continue to move, and the first contact rod 461 and the second contact rod 471 alternately contact the outer wall of the truncated cone portion 412 close to the mounting base 15. Since the diameter of the truncated cone portion 412 is larger at this point, the contact time per unit time is The truncated cone 412 can be rotated at a smaller angle to achieve a slow shaking of the truncated cone 412, thereby causing the mounting base 15 to also shake slowly. The first connecting portion 42 and the second connecting portion 44 continue to move. At this time, the first driving rod 462 and the second driving rod 472 begin to contact alternately with the side of the outer wall of the truncated cone 412 away from the mounting base 15. Since the diameter of the truncated cone 412 at this point is smaller, the truncated cone 412 can be rotated at a larger angle per unit time, thereby achieving a rapid shaking of the truncated cone 412. In this way, during the auxiliary feeding stroke, the speed of the mounting base 15 is changed from slow to fast. For the feeding process, it can ensure that the spokes can be stably inserted into the holes, and for the installation process, it can ensure that the spokes will not be stuck.

[0046] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
