When processing the rack, it is usually necessary to perform cutting, gear milling, heat treatment, grinding, straightening and aging treatment, punching and shaping on the blank. The rack needs a loading device to load it when passing through each process. The traditional loading method can only load one machine, with low loading efficiency and large footprint.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] In the description of the present invention, it is necessary to understand that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention.

[0025] See also Figure 1 - Figure 4 The embodiment of the present invention provides a technical solution: a rack processing device, including a workbench 1, a total of two workbench 1, and a guide rail 10, the guide rail 10 is fixed above the two workbench 1, and connecting pulleys 5 are slidably installed on the guide rail 10 at equal intervals, and the sliding connection between the guide rail 10 and the connecting pulley 5 is used to improve the stability of the connecting pulley 5 during movement.

[0026] In order to drive the movement of the connecting pulley 5, the rack processing device provided in this embodiment also includes a chain 4, which is installed above the guide rail 10 to drive the connecting pulley 5 to move on the guide rail 10. It should be noted that the two workbenches 1 are centrally symmetrical about the center of the chain 4. Preferably, the connection between the connecting pulley 5 and the chain 4 is a detachable connection to facilitate the later inspection and maintenance of the connecting pulley 5 and the chain 4.

[0027] Furthermore, to facilitate the processing of the rack body 26, the rack processing device provided in this embodiment also includes a rack processing machine tool 7, which is arranged between the two workbenches 1. It should be noted that the rack processing machine tool 7 on the same side is parallel to the straight section of the chain 4, so that a rack processing assembly line is formed between the rack processing machine tools 7 on the same side, thereby making there a total of two rack processing assembly lines in this embodiment, and further making it possible for one chain 4 to feed the two assembly lines synchronously, thereby improving the transmission effect of the chain 4. In addition, the distance between the two rack processing machines 7 on the same side is the same as the travel path distance between the two adjacent connecting pulleys 5, so that the rack body 26 can be synchronously processed inside different rack processing machines 7. It should be noted that the number of connecting pulleys 5 is preferably four more than the number of rack processing machines 7, so that the rack bodies 26 on the two assembly lines can be synchronously loaded and unloaded during processing in the later stage, which is convenient for clamping the rack body 26.

[0028] To facilitate the movement of the rack body 26 between the rack processing machines 7, the rack processing device provided in this embodiment also includes a connecting cylinder 6, which is fixed to the lower end of the connecting pulley 5, and a connecting frame 13 is fixed to the telescopic end of the connecting cylinder 6, and an electric telescopic cylinder 15 is rotatably installed on the connecting frame 13. The telescopic end of the electric telescopic cylinder 15 is provided with a fixing tool for fixing the rack body 26 to ensure the stability of the rack body 26 during processing and transportation.

[0029] To facilitate the cleaning of processing debris on the surface of the rack body 26, the rack processing device provided in this embodiment also includes a flipping component, which is arranged on the connecting pulley 5 and is used to fix the tooling to flip, so that the processing debris on the surface of the rack body 26 can be shaken off before entering the downstream rack processing machine 7, thereby avoiding the processing debris from affecting the processing of the rack body 26 and improving the practicability of the equipment.

[0030] In this embodiment, the connecting pulley 5 is driven to move synchronously by the hoisting chain 4, so that the fixed tooling under the connecting pulley 5 is moved, and then the rack body 26 is moved on each rack processing machine 7, which is beneficial to the assembly line processing of the rack body 26 and improves the work efficiency during the processing of the rack body 26. During the movement of the rack body 26, the processing debris on the surface of the rack body 26 is shaken off before entering the downstream rack processing machine 7 through the setting of the flip assembly, so as to avoid the processing debris affecting the processing of the rack body 26 and improve the practicability of the equipment. In addition, the chain 4 and the rack processing machine 7 cooperate to realize a dual assembly line setting, which is beneficial to improve the conveying effect of the rack body 26.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7As shown, the flip assembly includes a transmission rack 22 fixed to the outside of the guide rail 10, and the transmission rack 22 is arranged downstream of each rack processing machine 7. A transmission gear 24 meshing with the transmission rack 22 is rotatably installed inside the connecting pulley 5. Preferably, the length of the transmission rack 22 satisfies the rotation of the transmission gear 24 by an integer number of circles. The lower end of the connecting pulley 5 is provided with a telescopic tube fixedly connected to the center of the transmission gear 24. The lower end of the telescopic tube is synchronously lifted and lowered with the lower end of the connecting cylinder 6, and a first bevel gear 40 is installed at the lower end of the telescopic tube. A second bevel gear 41 meshing with the first bevel gear 40 is installed on the electric telescopic cylinder 15. It should be noted that the first bevel gear 40 can be selected as a worm, and the second bevel gear 41 is correspondingly selected as a worm wheel. The self-locking effect of the meshing between the worm wheel and the worm can prevent the electric telescopic cylinder 15 from actively rotating, and the lower end of the telescopic tube is synchronously lifted and lowered with the lower end of the connecting cylinder 6 to prevent the first bevel gear 40 from disengaging from the second bevel gear 41, thereby improving the stability during transmission.

[0032] In this embodiment, when the connecting pulley 5 moves to the transmission rack 22 on the guide rail 10, the telescopic tube rotates through the engagement of the transmission rack 22 and the transmission gear 24, further rotating the first bevel gear 40, and the electric telescopic cylinder 15 rotates through the engagement of the first bevel gear 40 and the second bevel gear 41, further driving the fixed tooling to flip.

[0033] like Figure 1 , Figure 3 , Figure 4 , Fig. 9 and Fig.10 As shown, in order to facilitate the loading and unloading of the rack body 26, the rack processing device provided in this embodiment also includes a loading and unloading assembly, which includes an equipment box 11. The equipment box 11 is fixed at the middle position on the workbench 1, and a first rotating arm 12 is rotatably installed on one side of the upper end of the equipment box 11, and a second rotating arm 38 is rotatably installed on the other side of the upper end of the equipment box 11.

[0034] It should be noted that, preferably, the first rotating arm 12 is a unloading arm, which is mainly used for unloading the rack body 26 on the fixed tooling, and the second rotating arm 38 is a loading arm, which is mainly used for loading the rack body 26 on the workbench 1 into the fixed tooling, and the angle between the first rotating arm 12 and the second rotating arm 38 is an acute angle to ensure that when the first rotating arm 12 grabs the rack body 26 on the fixed tooling, the second rotating arm 38 synchronously grabs the rack body 26 on the workbench 1, and during this process, the rotation angle between the first rotating arm 12 and the second rotating arm 38 is the same.

[0035] In addition, the loading and unloading assembly provided in this embodiment further includes a lifting cylinder 31. The lifting cylinder 31 is respectively fixed to one ends of the first rotating arm 12 and the second rotating arm 38 away from the equipment box 11, and a suction cup 32 for grasping the rack body 26 is installed at the telescopic end of the lifting cylinder 31. Of course, the suction cup 32 can also be an electromagnet, and the rack body 26 is magnetically attracted by the electromagnet to achieve the grasping of the rack body 26, so as to avoid the problem of difficult grasping of the suction cup 32 after the processing of the rack body 26 is completed.

[0036] In addition, to drive the first rotating arm 12 and the second rotating arm 38 to rotate synchronously, the loading and unloading assembly provided in this embodiment further includes a transmission assembly. The transmission assembly is arranged inside the equipment box 11 to drive the first rotating arm 12 and the second rotating arm 38 to rotate in the same direction, so as to facilitate the synchronous unloading and clamping of the rack body 26.

[0037] As Figure 3 and Figure 4 shown, the telescopic tube provided in this embodiment includes a sleeve 30 fixed to the lower end of the connecting trolley 5. A lifting rod 39 is slidably installed inside the sleeve 30. Preferably, the cross-section of the lifting rod 39 is a regular polygon to prevent the lifting rod 39 from rotating inside the sleeve 30.

[0038] In addition, to prevent the first bevel gear 40 from disengaging from the second bevel gear 41 and improve the stability of the transmission between the first bevel gear 40 and the second bevel gear 41, a connecting plate 42 is fixed to the telescopic end of the connecting cylinder 6. The lifting rod 39 is rotatably connected to the connecting plate 42, and the lower end of the lifting rod 39 is fixedly connected to the first bevel gear 40 to ensure the synchronous lifting of the first bevel gear 40 and the second bevel gear 41.

[0039] As Figure 1 、 Figure 3 、 Figure 7 and Figure 8 shown, the fixed tooling tongue plate 14 provided in this embodiment is arranged at the lower end inside the connecting frame 13. The tongue plate 14 is fixedly connected to the connecting frame 13, and the connection can be selected as bolt connection, riveting or welding. It should be noted that preferably the connecting frame 13 is in an inverted "U" shape structure to facilitate the installation of the tongue plate 14.

[0040] To facilitate the loading of the rack body 26, the fixed tooling provided in this embodiment further includes a carrier 23. The carrier 23 is arranged above the tongue plate 14, and one side of the carrier 23 is fixedly connected to the telescopic end of the electric telescopic cylinder 15. An installation groove 25 is provided on the upper surface of the carrier 23 for placing the rack body 26. Preferably, the installation groove 25 is open on one side facing the rack processing machine tool 7 and on the upper surface, so as to facilitate the processing, loading and unloading of the rack body 26 inside the installation groove 25. Preferably, the upper surface of one end of the tongue plate 14 close to the rack processing machine tool 7 is a slope structure to facilitate the movement of the carrier 23 on the tongue plate 14.

[0041] In this embodiment, the carrier frame 23 is driven to move by the electric telescopic cylinder 15, so that the carrier frame 23 extends into the rack processing machine 7 to achieve horizontal movement of the carrier frame 23, which is beneficial for the rack processing machine 7 to directly process the rack body 26 on the mounting groove 25.

[0042] In order to achieve the fixation of the rack body 26, the fixing tool provided in this embodiment also includes a pressure plate 27, which is installed at the two end positions inside the installation groove 25. The two ends of the outer side of the carrier frame 23 are fixed with clamping cylinders 28 for driving the pressure plates 27 to move toward each other. The upper end of the pressure plate 27 is preferably an arc structure, so that an inverted "eight" structure is formed between the two pressure plates 27. The installation of the rack body 26 can be achieved without accurately aligning the rack body 26 with the installation groove 25, thereby improving the fault tolerance rate during the installation of the rack body 26. It should be noted that in order to improve the processing accuracy of the rack body 26, the pressure plate 27 is preferably a metal workpiece, which can be selected from hard metal materials such as stainless steel, pure copper or aluminum alloy to avoid the deformation of the pressure plate 27 causing the position of the rack body 26 to be offset after clamping, thereby causing the problem of reduced processing accuracy.

[0043] like Fig.10 As shown, the transmission assembly provided in this embodiment includes a servo motor 33, which is fixed inside the equipment box 11, and a driving gear 34 is fixed at the output end of the servo motor 33. The transmission assembly provided in this embodiment also includes a rotating shaft 36, which is rotatably installed on both sides of the equipment box 11. Bearings are provided at the connections between the two ends of the rotating shaft 36 and the equipment box 11 to facilitate the rotation of the rotating shaft 36, and the upper ends of the two rotating shafts 36 pass through the upper surface of the equipment box 11 and are fixedly connected to the first rotating arm 12 and the second rotating arm 38 respectively. The preferred fixed connection method is welding to ensure the stability of the first rotating arm 12 and the second rotating arm 38 after installation. In addition, a limit gear 37 is fixedly sleeved on the two rotating shafts 36, and the limit gear 37 is preferably a half gear; the transmission assembly provided in this embodiment also includes a linkage gear 35, which is rotatably installed inside the equipment box 11, and the linkage gear 35 is located between the driving gear 34 and the limit gear 37, and the linkage gear 35 is meshed with the driving gear 34 and the limit gear 37.

[0044] In this embodiment, the servo motor 33 drives the driving gear 34 to rotate, and the interlocking gear 35 is rotated through the meshing between the driving gear 34 and the interlocking gear 35. Further, the interlocking gear 35 is meshed with the limiting gear 37, so that the limiting gear 37 drives the rotating shaft 36 to rotate, thereby causing the first rotating arm 12 and the second rotating arm 38 to rotate respectively.

[0045] like Figure 1 , Figure 3 and Figure 8As shown, in order to facilitate the positioning of the rack body 26 during processing, a positioning column 8 is fixed on the front surface of the rack processing machine 7, a laser sensor is provided on the upper end of the positioning column 8, and a hole groove 29 adapted to the laser sensor is opened on the lower surface of the tongue plate 14.

[0046] It should be noted that the laser sensor is a sensor that uses laser technology for measurement. It is composed of a laser, a laser detector and a measuring circuit. Its advantages are that it can realize non-contact long-distance measurement, fast speed, high accuracy, large range, and strong resistance to light and electrical interference. Using the above principle, we use a laser sensor to measure the distance between the positioning column 8 and the tongue plate 14. When the hole groove 29 on the tongue plate 14 corresponds to the laser sensor, the distance measured by the laser sensor becomes larger, thereby judging the position of the hole groove 29, thereby realizing the positioning of the rack body 26 during processing.

[0047] like Figure 1 - Figure 5 As shown, in order to facilitate the driving of the chain 4, sprockets 2 are rotatably installed on the upper ends of the two workbenches 1, the two sprockets 2 are adapted to the chain 4, and a driving motor 3 is fixed above one of the sprockets 2, and the driving motor 3 drives one of the sprockets 2 to rotate, and one of the sprockets 2 is rotated by the driving motor 3, and the chain 4 is driven by the transmission action of the sprocket 2 and the chain 4.

[0048] It should be noted that, in order to facilitate the control of the working process of the present equipment, a control cabinet 16 is installed on the workbench 1. The signal input end of the control cabinet 16 is electrically connected to the signal output end of the laser sensor, and the signal output end of the control cabinet 16 is electrically connected to the drive motor 3, the servo motor 33 and the electric telescopic cylinder 15 respectively. When the control cabinet 16 receives the distance signal of the laser sensor, it ensures that the distance signal is the same as the distance between the positioning column 8 and the hole groove 29, thereby locating the position of the hole groove 29, and then locating the position of the fixed tooling. At this time, the control cabinet 16 sends a signal to control the drive motor 3 to stop working, so that the fixed tooling position remains unchanged. The servo motor 33 is controlled by the control cabinet 16 to make the first rotating arm 12 and the second rotating arm 38 rotate respectively, so as to realize the synchronous unloading and clamping of the rack body 26. The electric telescopic cylinder 15 is extended by the control cabinet 16, so that the rack body 26 enters the rack processing machine 7, and then realizes the synchronous processing of the rack body 26.

[0049] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, in order to facilitate the storage of the rack body 26 on the workbench 1, a material receiving assembly is opened on the workbench 1, and the material receiving assembly includes a material receiving trough 17, and the material receiving trough 17 is opened on the workbench 1, and a material receiving box 9 is slidably installed inside the material receiving trough 17 to facilitate the movement of the material receiving box 9, and a handle 19 is installed at one end of the material receiving box 9 away from the material receiving trough 17. The handle 19 facilitates the pulling of the material receiving box 9, thereby facilitating the collection of the rack body 26 inside the material receiving box 9.

[0050] In order to avoid the rack body 26 from colliding and causing surface scratches during unloading, the material receiving assembly provided in this embodiment also includes an inclined plate 18, which is arranged inside the material receiving box 9, and the angle between the inclined plate 18 and the horizontal plane is an acute angle. The height of the inclined plate 18 on one side facing the material receiving trough 17 is greater than the height on the other side. Preferably, the inclined plate 18 is a workpiece made of rubber material to improve the buffering effect of the rack body 26 during unloading. When the rack body 26 is unloading, it falls onto the inclined plate 18. Due to the structural characteristics of the inclined plate 18, the rack body 26 slides along the inclined plate 18 to the bottom of the material receiving box 9, thereby reducing the surface scratches caused by the rack body 26 colliding during unloading.

[0051] like Figure 5 and Figure 6 As shown, in order to facilitate the fixation of the material receiving box 9, baffle bars 21 are rotatably installed on the outer wall of the workbench 1 at both sides of the material receiving trough 17, and the material receiving box 9 is symmetrically provided with limit grooves 20 adapted to the baffle bars 21. By rotating the baffle bars 21, the baffle bars 21 are embedded in the limit grooves 20, so that the material receiving box 9 is fixed inside the material receiving trough 17, preventing the material receiving box 9 from slipping out of the material receiving trough 17 and causing a decrease in the material receiving effect.

[0052] In addition, the material receiving component can also be a first conveyor belt arranged on the workbench 1, so that the rack body 26 is directly placed on the first conveyor belt during unloading, thereby transporting the rack body 26 to the outside of the equipment. Of course, a second conveyor belt can also be arranged on the workbench 1. The second conveyor belt is mainly used for loading the rack body 26 embryo, and transporting the rack body 26 embryo to the workbench 1, so that the suction cup 32 on the second rotating arm 38 can grab the rack body 26 embryo.

[0053] When in use (working), the lifting cylinder 31 is started to adjust the height of the suction cup 32 so that the suction cup 32 grabs the rack body 26, and the servo motor 33 is started. The servo motor 33 drives the driving gear 34 to rotate, and the driving gear 34 is meshed with the linkage gear 35, so that the linkage gear 35 is rotated, and further the linkage gear 35 is meshed with the limit gear 37, so that the limit gear 37 drives the rotating shaft 36 to rotate, so that the first rotating arm 12 and the second rotating arm 38 are rotated respectively, and further the rack body 26 on the fixed tooling is moved to the top of the receiving trough 17, so that the rack body 26 blank on the workbench 1 is moved to the fixed tooling, and at this time, the two suction cups 32 release the rack body 26 and the rack body 26 blank respectively, so that the rack body 2 6 falls into the material receiving box 9. When the rack body 26 is unloading, it falls onto the inclined plate 18. Due to the structural characteristics of the inclined plate 18, the rack body 26 slides along the inclined plate 18 to the bottom of the material receiving box 9, thereby reducing the surface scratches caused by the collision of the rack body 26 during unloading. By forming an inverted "eight" structure between the two pressure plates 27, the installation of the rack body 26 blank can be achieved without accurately aligning the rack body 26 blank with the installation groove 25, thereby improving the fault tolerance rate during the installation of the rack body 26 blank. After the rack body 26 blank moves to the inside of the installation groove 25, the clamping cylinder 28 is started, and the clamping cylinder 28 makes the pressure plates 27 move toward each other, so that the pressure plates 27 clamp the rack body 26 blank, thereby improving the stability of the rack body 26 blank during subsequent processing.

[0054] At this time, the driving motor 3 is started, and one of the sprockets 2 is rotated by the driving motor 3. Under the transmission action of the sprocket 2 and the chain 4, the chain 4 works, and the fixed tooling under the connecting pulley 5 is further moved, and then the rack body 26 is moved on each rack processing machine 7, which is beneficial to the assembly line processing of the rack body 26 and improves the working efficiency during the processing of the rack body 26. Through the cooperation of the chain 4 and the rack processing machine 7, a double assembly line setting is realized, which is beneficial to improve the conveying effect of the rack body 26. When the connecting pulley 5 moves to the transmission rack 22 on the guide rail 10, the transmission rack 22 is meshed with the transmission gear 24 to rotate the telescopic tube, and further rotate the first bevel gear 40. The first bevel gear 40 is meshed with the second bevel gear 41 to rotate the electric telescopic cylinder 15, which further drives the fixed tooling to flip, so that the processing debris on the surface of the rack body 26 is shaken off before entering the downstream rack processing machine 7, so as to avoid the processing debris affecting the processing of the rack body 26 and improve the practicability of the equipment.

[0055] When the fixed tooling passes through the positioning column 8, the control cabinet 16 receives the distance signal of the laser sensor to ensure that the distance signal is the same as the distance between the positioning column 8 and the hole groove 29, thereby locating the position of the hole groove 29, and then locating the position of the fixed tooling. At this time, the control cabinet 16 sends a signal to control the drive motor 3 to stop working, so that the position of the fixed tooling remains unchanged. The servo motor 33 is controlled by the control cabinet 16 to rotate the first rotating arm 12 and the second rotating arm 38 respectively, so as to realize the synchronous unloading and clamping of the rack body 26. The electric telescopic cylinder 15 is extended by the control cabinet 16, so that the rack body 26 enters the interior of the rack processing machine 7, and then realizes the synchronous processing of the rack body 26.
