DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. If not specifically indicated, the technical means used in the embodiments are conventional means familiar to those skilled in the art.

[0035] In the description of the invention, it should be understood that the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the invention, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the invention.

[0036] A flow production line, comprising a chain conveying line 1 and a machining assembly. The chain conveying line 1 is used to convey workpieces, and the machining assembly is arranged along the conveying line to machine the workpieces. Wherein, the chain conveying line 1 comprises a plurality of connecting pieces 12 and a plurality of chain plates 11 connected in sequence. Along the conveying direction of the chain conveying line 1, the two sides of the chain plate 11 are respectively provided with a first matching part 111 and a second matching part 112. The first matching part 111 is provided with a first through hole 1111, and the second matching part 112 is provided with a second through hole 1121. The axis of the first through hole 1111 and the second through hole 1121 is parallel. The first matching part 111 of one of the two adjacent chain plates 11 and the second matching part 112 of the other are matched, so that the axis of the first matching part 111 and the axis of the second matching part 112 coincide.

[0037] The connecting piece 12 comprises a shaft body 121 and an abutting part 123. The shaft body 121 is arranged through the first through hole 1111 and the second through hole 1121. Along the axial direction of the shaft body 121, one end of the shaft body 121 is provided with a limiting part 122, and the abutting part 123 is eccentrically connected to the other end of the shaft body 121. The rotation axis of the abutting part 123 is parallel to the axis of the shaft body 121.

[0038] The abutting part 123 comprises a storage state and a limiting state. When the abutting part 123 is in the storage state, the projection of the abutting part 123 on the end face of the shaft body 121 is located within the end face of the shaft body 121 along the axial direction of the shaft body 121, so that the end of the shaft body 121 provided with the abutting part 123 can pass through the first through hole 1111 and the second through hole 1121. When the abutting part 123 is in the limiting state, the projection of the abutting part 123 on the end face of the shaft body 121 is located outside the end face of the shaft body 121. The abutting part 123 and the limiting part 122 cooperate to limit the shaft body 121.

[0039] The machining assembly can include various machining components, which can include one or more, for example, the machining components can include a circular saw component 3, a lathe and a centerless grinding machine, which can be provided with one or more respectively.

[0040] The chain plate conveying line 1 and the machining assembly form a flow production line, so that the workpiece can pass through the chain plate conveying line 1 between the machining assemblies, and the production efficiency is improved.

[0041] The chain plate 11 of the chain plate conveying line 1 forms a bearing surface for placing the workpiece. When the chain formed by the plurality of chain plates 11 connected end to end rotates, the chain plate 11 moves to achieve the purpose of conveying the workpiece. The driving structure of the chain can be selected in the prior art, which will not be described here.

[0042] The first fitting part 111 and the second fitting part 112 are connected, so that the two adjacent chain plates 11 can be rotatably connected. Specifically, when the shaft body 121 is arranged in the first through hole 1111 and the second through hole 1121, the two chain plates 11 can be connected and can rotate relative to each other.

[0043] The limiting part 122 and the abutting part 123 cooperate to prevent the shaft body 121 from being pulled out of the first through hole 1111 and the second through hole 1121. For example, the shaft body 121 passes through the first through hole 1111 and the second through hole 1121 from one end of the first through hole 1111. The limiting part 122 and the abutting part 123 sandwich the first fitting part 111 and the second fitting part 112 therebetween, so that the shaft body 121 cannot be pulled out of the first through hole 1111 and the second through hole 1121.

[0044] The eccentric rotation of the abutting part 123 on the shaft body 121 means that the rotation center of the abutting part 123 is greater than 0 from the shaft center of the shaft body 121, so that the abutting part 123 has a receiving state and a limiting state.

[0045] When the abutting part 123 is in the receiving state, the abutting part 123 is projected on the end face of the shaft body 121, and the shaft body 121 can freely pass through the first through hole 1111 and the second through hole 1121, so that the connecting piece 12 can be installed on the chain plate 11.

[0046] When the abutting part 123 is in the limiting state, the abutting part 123 is projected on the end face of the shaft body 121. At this time, the shaft body 121 cannot pass through the first through hole 1111 and the second through hole 1121 due to the limiting action of the abutting part 123. When the connecting piece 12 is installed, the abutting part 123 is switched to the limiting state to limit the shaft body 121, preventing the shaft body 121 from being pulled out of the first through hole 1111 and the second through hole 1121.

[0047] The traditional chain plate 11 connection mode includes at least two components, for example, a pin shaft and a blocking piece, the pin shaft is provided with a fixed hole penetrating the pin shaft in the radial direction at both ends, the pin shaft is arranged in the first through hole 1111 and the second through hole 1121, and the two ends of the pin shaft are not blocked by the first through hole 1111 and the second through hole 1121, and then the blocking piece is inserted into the fixed hole.

[0048] This connection mode is complex in steps and increases the number of separate components of the chain, which is not convenient for installation and storage. For example, if a blocking piece is missing, the chain cannot be normally installed.

[0049] In the embodiment of the application, the connection of the two chain plates 11 can be completed by using only one component of the connecting piece 12, which is convenient for connecting the chain plates 11 to form a chain and reduces the risk of the chain being unable to be normally installed due to the lack of components.

[0050] In some embodiments, the connecting piece 12 further includes a control shaft 125, an elastic member 126 and a guide portion 124, the shaft body 121 is eccentrically provided with a sliding hole in the axial direction of the shaft body 121, the control shaft 125 is inserted into the sliding hole, the elastic member 126 is connected to the shaft body 121 and the control shaft 125, the abutting portion 123 is connected to the control shaft 125, the side wall surface of the abutting portion 123 is provided with a driving sliding groove 1231, the driving sliding groove 1231 is curved and extends away from the reference axis parallel to the axis of the shaft body 121, and the guide portion 124 is connected to the shaft body 121 and partially arranged in the driving sliding groove 1231.

[0051] The control shaft 125 is inserted into the sliding hole, on the one hand, the control shaft 125 can rotate relative to the shaft body 121, and on the other hand, the control shaft 125 can move in the axial direction of the shaft body 121.

[0052] The abutting portion 123 is connected to the control shaft 125, on the one hand, so that the abutting portion 123 can rotate relative to the shaft body 121, and on the other hand, so that the abutting portion 123 can move in the axial direction of the shaft body 121.

[0053] The guide portion 124 and the driving sliding groove 1231 cooperate to facilitate the rotation of the abutting portion 123, specifically, since the driving groove is curved and extends away from the reference axis, the guide portion 124 is inserted into the driving sliding groove 1231, so when the abutting portion 123 moves in the axial direction of the shaft body 121, the guide portion 124 pushes the abutting portion 123 to rotate, so that the abutting portion 123 switches between the storage state and the limiting state.

[0054] The elastic member 126 can be used to provide an elastic force for moving the control shaft 125 into the sliding hole, thereby being able to provide power for driving the abutting portion 123 to rotate, and the elastic member 126 can be a spring, and the two ends of the spring are connected to the shaft body 121 and the control shaft 125.

[0055] The driving sliding groove 1231 is curved from the side close to the shaft body 121 to the side away from the shaft body 121 along the reference axis, that is, when the abutting part 123 is located close to the shaft body 121, the abutting part 123 is in the limiting state, and when the abutting part 123 is located away from the shaft body 121, the abutting part 123 is in the storage state. When the connecting piece 12 is installed, the control shaft 125 can be moved first, so that the abutting part 123 can be switched to the storage state. One end of the shaft body 121 provided with the abutting part 123 passes through the first through hole 1111 and the second through hole 1121. When the abutting part 123 moves out of the first through hole 1111 and the second through hole 1121, the control shaft 125 is pulled back to the original position under the action of the elastic piece 126, and then the abutting part 123 rotates to the limiting state. The abutting part 123 and the limiting part 122 cooperate to prevent the shaft body 121 from being pulled out of the first through hole 1111 and the second through hole 1121.

[0056] Compared with the traditional chain plate 11 connection mode, the chain plate 11 of the embodiment only needs to be connected to two chain plates 11 through the connecting piece 12, thereby reducing the number of separate parts. Moreover, the connection process can be realized without professional tools, so that the chain plate 11 is convenient and fast to install.

[0057] In some embodiments, the flow production line further comprises a loading component 2 for moving the workpiece to the machining position of the machining assembly. The loading component 2 comprises a three-axis moving assembly and a clamping component 24 connected to the three-axis moving assembly. The three-axis moving assembly is used to move the clamping component 24 in space, and the clamping component 24 is used to clamp the workpiece.

[0058] The loading component 2 facilitates the movement of the workpiece conveyed by the chain plate conveying line 1 to the machining position, and also facilitates the placement of the machined workpiece on the chain plate conveying line 1. Specifically, the three-axis moving assembly can move the clamping component 24 in space, so that the clamping component 24 can be moved to a specified position to clamp the workpiece.

[0059] In some embodiments, the three-axis moving assembly comprises a first sliding rail 21, a second sliding rail 22 and a third sliding rail 23. The first sliding rail 21 extends along a first direction. The second sliding rail 22 is slidingly connected to the first sliding rail 21 and extends along a second direction. The third sliding rail 23 is slidingly connected to the second sliding rail 22 and extends along a third direction. The clamping component 24 is slidingly connected to the third sliding rail 23. The first direction, the second direction and the third direction are perpendicular to each other.

[0060] The first direction can be the direction indicated by the X axis in the figure, and the first direction can also be the conveying direction of the chain plate conveying line 1. The second direction can be the direction indicated by the Y axis in the figure, and the third direction can be the direction indicated by the Z axis in the figure. The third direction can also be a vertical direction.

[0061] The second slide rail 22 is slidingly connected to the first slide rail 21, so that the second slide rail 22 can move in the first direction. The third slide rail 23 is slidingly connected to the second slide rail 22, so that the third slide rail 23 can move in the third direction. The clamping component 24 is slidingly connected to the third slide rail 23, so that the clamping component 24 can move in the third direction. Under the action of the first slide rail 21, the second slide rail 22 and the third slide rail 23, the clamping component 24 can move in the space, so that the clamping component 24 can transfer the workpiece in the space.

[0062] In some embodiments, the clamping component 24 comprises a seat body 241, a first clamping part 242 and a second clamping part, and a locking part. The seat body 241 is connected to the three-axis moving assembly. The first clamping part 242 is movably arranged on the seat body 241 in the fourth direction. The second clamping part comprises a fixed part 245 and a turnover part 246. The fixed part 245 is connected to the seat body 241. The turnover part 246 is rotationally connected to the fixed part 245. The rotation axis of the turnover part 246 is perpendicular to the fourth direction. The turnover part 246 and the first clamping part 242 are arranged in the fourth direction. The locking part is used to lock the turnover part 246 to the fixed part 245.

[0063] The fourth direction can be the same as the third direction. The fourth direction can also be a vertical direction.

[0064] The clamping part commonly used for clamping the workpiece usually comprises a clamping end which can be separated and folded. The disadvantage of this clamping method is that the space required for clamping the workpiece is large, and it is difficult to clamp the workpiece in a narrow space. For example, in order to prevent the workpiece from falling off the chain plate 11, a baffle can be arranged on both sides of the chain plate conveying line 1 perpendicular to the conveying direction of the chain plate conveying line 1. When clamping the workpiece between the baffles, the conventional clamping part can not clamp normally.

[0065] The first clamping part 242 can be driven by a hydraulic cylinder or a pneumatic cylinder, so that it can move in the fourth direction.

[0066] The turnover part 246 can rotate relative to the fixed part 245, which facilitates the turnover part 246 to shovel the workpiece. For example, the initial state of the turnover part 246 can be an inclined state. When clamping the workpiece, the clamping component 24 is first lowered until the turnover part 246 abuts against the chain plate 11. Then, in order to move the workpiece above the turnover part 246, the clamping component 24 can move towards the baffle. Under the limiting action of the baffle, the workpiece is shoveled. Then, the first clamping part 242 moves towards the turnover part 246, and under the action of the two, the workpiece is clamped.

[0067] The locking part is used to lock the turnover part 246, so as to prevent the turnover part 246 from rotating when the turnover part 246 and the first clamping part 242 cooperate in the clamping state.

[0068] Compared with the traditional clamping piece, the clamping part 24 of the embodiment of the application requires smaller operation space when clamping the workpiece, and is convenient for clamping the workpiece in a narrow space.

[0069] In some embodiments, the locking piece includes a piston cavity 244, a piston 243, and an air bag 248. The piston cavity 244 is arranged in the seat body 241. The piston 243 is in movable sealing connection with the inner wall of the piston cavity 244. The piston 243 is connected to the first clamping part 242. One of the fixed part 245 and the turnover part 246 is provided with a shaft sleeve 247. The other one of the fixed part 245 and the turnover part 246 is provided with a rotating shaft 2410. The rotating shaft 2410 is arranged in the shaft sleeve 247, so that the fixed part 245 and the turnover part 246 are rotationally connected. The side wall surface of the shaft sleeve 247 is internally provided with a containing cavity. The air bag 248 is arranged in the containing cavity. Part of the surface wall of the air bag 248 is fixed to the side of the containing cavity away from the rotating shaft 2410. The surface wall surface of the air bag 248 is provided with a column body 249. The inner side wall of the shaft sleeve 247 is provided with a guide hole 2411. The guide hole 2411 is in communication with the containing cavity. The circumferential wall surface of the rotating shaft 2410 is provided with a plurality of limiting holes 2412 around the axis of the rotating shaft 2410. The column body 249 is inserted into the limiting hole 2412 through the guide hole 2411. The air bag 248 is in communication with the piston cavity 244.

[0070] The piston 243 is connected to the first clamping part 242, so that the first clamping part 242 can control the movement of the piston 243. When the piston 243 moves, the air pressure in the air bag 248 changes, so that the column body 249 can move along the guide hole 2411.

[0071] The rotating shaft 2410 and the shaft sleeve 247 cooperate, so that the turnover part 246 and the fixed part 245 can be rotationally connected.

[0072] The containing cavity can be annular around the axis of the shaft sleeve 247. Correspondingly, the air bag 248 can also be annular arranged in the containing cavity.

[0073] The side of the containing cavity away from the rotating shaft 2410 refers to the side of the containing cavity away from the rotating shaft 2410 in the radial direction of the rotating shaft 2410. In the embodiment in which the containing cavity is annular, the side can be the outer circular side wall of the containing cavity. The air bag 248 can be bonded with the surface wall surface of the containing cavity. By fixing the air bag 248 to the side of the containing cavity away from the rotating shaft 2410, when the air bag 248 expands or shrinks, the column body 249 can move in the radial direction of the shaft body 121.

[0074] The column 249 cooperates with the limiting hole 2412 to lock the rotating shaft 2410, that is, when the air bag 248 expands, the column 249 is inserted into the limiting hole 2412, at this time the rotating shaft 2410 cannot rotate relative to the shaft sleeve 247, on the contrary, when the air bag 248 contracts, the column 249 is withdrawn from the limiting hole 2412, and the rotating shaft 2410 can rotate relative to the shaft sleeve 247.

[0075] The piston 243 is controlled to move by the first clamping part 242, and then the expansion and contraction of the air bag 248 are controlled to realize the locking of the rotating shaft 2410, on the one hand, the first clamping part 242 and the locking part form linkage, and the working reliability of the clamping part 24 is improved, and on the other hand, the first clamping part 242 and the locking part are controlled at the same time.

[0076] In some embodiments, the processing assembly includes a circular saw part 3, a machining part 4 and a centerless grinding machine part 5, which are arranged in sequence along the chain plate conveying line 1.

[0077] The blank is cut by the circular saw part 3 so that the blank has a designed length, the blank is machined by the machining part 4 to form the features of the workpiece, and then the blank is ground by the centerless grinding machine so that the workpiece can be in the shape of a shaft.

[0078] The machining part 4 can be a lathe, a planer, a milling machine or a punch, etc. The specific machining equipment is selected according to the machining requirements of the workpiece.

[0079] The structures and working principles of the circular saw part 3, the machining part 4 and the centerless grinding machine part 5 are known to those skilled in the art, and will not be described here.

[0080] In some embodiments, first and second baffles 13 and 14 are respectively arranged on the two sides of the chain plate conveying line 1 in a direction perpendicular to the conveying direction of the chain plate conveying line 1, the first baffle 13 includes a shielding part 132 and an inclined part 131, the shielding part 132 and the second baffle 14 are arranged obliquely, and the inclined part 131 is connected to the shielding part 132.

[0081] The first and second baffles 13 and 14 cooperate to reduce the risk of the workpiece falling off the chain plate conveying line 1, and the inclined part 131 is used to guide the workpiece, that is, the workpiece is placed on the inclined part 131, and the workpiece can roll from the inclined part 131 to between the shielding part 132 and the second baffle 14. If the machining part 4 has a discharge port, the inclined part 131 can extend to the discharge port of the machining part 4, so that after the machining part 4 finishes machining the workpiece, the workpiece can roll from the inclined part 131 to the chain plate conveying line 1 and be conveyed to the next station by the chain plate conveying line 1.

[0082] In some embodiments, two sides of the chain conveying line 1 are respectively provided with a third baffle 15 and a fourth baffle 16 in a direction perpendicular to the conveying direction of the chain conveying line 1, and the spacing between the third baffle 15 and the fourth baffle 16 is smaller than the spacing between the first baffle 13 and the second baffle 14.

[0083] In the conveying direction of the chain conveying line 1, the third baffle 15 and the fourth baffle 16 can be arranged behind the first baffle 13 and the second baffle 14. The third baffle 15 and the fourth baffle 16 further precisely control the position of the workpiece on the chain plate 11.

[0084] The ends of the third baffle 15 and the fourth baffle 16 can be provided with a centerless grinding machine, so that the workpiece is accurately sent between the grinding wheel and the adjusting wheel of the centerless grinding machine.

[0085] The fifth baffle 17 can be arranged between the third baffle 15 and the fourth baffle 16, and the fifth baffle 17 includes a bent portion 171 bent towards the third baffle 15 or the fourth baffle 16. The fifth baffle 17 precisely positions the workpiece.

[0086] In some embodiments, the assembly line further includes a feeding component 6, and the feeding component 6 includes a support frame 61, a feeding assembly 63, and a discharging assembly. The feeding assembly 63 includes a first seat body 631 and a second seat body 632, and the first seat body 631 and the second seat body 632 are oppositely arranged in a direction perpendicular to the conveying direction of the chain conveying line 1. The first seat body 631 is rotatably provided with a closing rod connected to the second seat body 632. The support frame 61, the first seat body 631, the second seat body 632, and the closing rod form a feeding channel extending in the conveying direction of the chain conveying line 1. The feeding assembly 63 and the discharging assembly are arranged in a direction perpendicular to the conveying direction of the chain conveying line 1. The discharging assembly includes a support plate 62 rotatably arranged on the support frame 61, and the rotation axis of the support plate 62 is parallel to the conveying direction of the chain conveying line 1.

[0087] The feeding channel formed by the support frame 61, the first seat body 631, the second seat body 632, and the closing rod is used to guide the workpiece to the chain conveying line 1. Since the closing rod is rotatably arranged on the first seat body 631, the closing rod can rotate relative to the first seat body 631. The closing rod can abut against the second seat body 632 or be connected to the second seat body 632 by a latch. When the closing rod is in an open state, the workpiece can be placed into the feeding channel from the gap between the first seat body 631 and the second seat body 632. When the closing rod is in a closed state, i.e., the closing rod is connected to the second seat body 632, the feeding channel is closed by the closing rod, preventing the workpiece from escaping from the feeding channel.

[0088] The support plate 62 is used to support the workpiece.

[0089] The feeding assembly 63 and the discharging assembly are arranged in a direction perpendicular to the conveying direction of the chain plate conveying line 1, i.e. the first seat body 631 or the second seat body 632 can be arranged opposite to the support plate 62.

[0090] In addition, the support plate 62 is rotationally connected to the support frame 61, so when the support plate 62 is rotated to be inclined, the workpiece will move to the low side of the support plate 62, so that the low side of the support plate 62 is close to the feeding assembly 63, and the workpiece can abut against the first seat body 631 or the second seat body 632, thereby facilitating the movement of the workpiece into the feeding channel.

[0091] The driving structure of the support plate 62 can be selected in the prior art, which will not be described here.

[0092] The above embodiments only describe the preferred modes of the application, and do not limit the scope of the application. Any modification, transformation, modification and replacement of the technical solutions of the application made by those skilled in the art without departing from the spirit of the application shall fall within the protection scope determined by the claims of the application.
