[0049] 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.

[0050] The core of the present invention is to provide a crankshaft oil circuit plugging device, which can improve the installation efficiency of steel balls and reduce the labor intensity of workers.

[0051] For a specific embodiment of the crankshaft oil circuit plugging device provided by the present invention, please refer to Figures 3 to 11 , including a press-fitting module, which includes: a steel ball silo 2, a steel ball conveying device 3, a steel ball diverting device 4 and at least two steel ball press-fitting devices 5.

[0052] The inlet of the steel ball conveying device 3 is connected to the outlet of the steel ball silo 2 .

[0053] The steel ball diverter device 4 includes a diverter pipeline 41 and a diverter structure. The diverter pipeline 41 includes a feed channel 411 and at least two discharge channels 412 that are simultaneously connected to the outlet of the feed channel 411. The diverter structure is arranged at the docking point between the feed channel 411 and each discharge channel 412, so that the feed channel 411 can be switched and connected to each discharge channel 412, that is, through the arrangement of the diverter structure, the feed channel 411 can be connected to one of the discharge channels 412 in turn. The outlets of each discharge channel 412 face the corresponding preset steel ball press-fitting position A respectively.

[0054] Specifically, the shunt pipe 41 is tilted, with the high end being the inlet of the feed channel 411 and the low end being the outlet of the discharge channel 412 , so that the steel balls 12 can flow in the shunt pipe 41 by virtue of their own weight.

[0055] The output end of each steel ball pressing device 5 respectively moves telescopically through the corresponding preset steel ball pressing position A. Specifically, the steel ball pressing device 5 is a hydraulic oil cylinder. Specifically, the steel ball pressing device 5 is arranged on the oil cylinder support seat, and the oil cylinder support seat is arranged on the bed 10. The steel ball pressing device 5 controls the forward and backward movement of its pressing rod 51 through hydraulic pressure.

[0056] When in use, the crankshaft 1 is placed at a set position, and the inlets of the oil process holes 11 on the crankshaft 1 are respectively located at the preset steel ball press-fitting positions A. The steel ball conveying device 3 conveys the steel balls 12 in the steel ball silo 2 to the feed channel 411 one by one, and the diversion structure switches the connection between the feed channel 411 and each discharge channel 412, so that each steel ball 12 is conveyed to a different preset steel ball press-fitting position A through a different discharge channel 412, so as to enter the inlet of the corresponding oil process hole 11, and the steel ball press-fitting device 5 presses the steel ball 12 at the inlet of the corresponding oil process hole 11 into the corresponding oil process hole 11, so as to realize the simultaneous press-fitting of the steel balls 12 of different oil process holes 11.

[0057] In this embodiment, through the coordinated action of the steel ball conveying device 3, the steel ball diverting device 4 and the steel ball pressing device 5, the automatic conveying and pressing of the steel balls 12 can be realized without adjusting the position and angle of the crankshaft 1. Through the action of different discharge channels 412 and the steel ball pressing device 5, the steel balls 12 of different oil circuit process holes 11 on the crankshaft 1 can be pressed, which can improve the installation efficiency of the steel balls 12 and reduce the labor intensity of the staff.

[0058] Furthermore, if Figure 3 , Figures 6 to 9As shown, the diversion structure includes a movable block 42 rotatably arranged at the docking position, at least two swing arms 421 are sequentially arranged on the movable block 42 around its rotation center line, the two discharge channels 412 are respectively the first channel 413 and the second channel 414, the two side walls of the feed channel 411 are respectively the first side wall 415 and the second side wall 416, the first side wall 415 of the feed channel 411 is docked with the first channel 413 and the second side wall 416 is docked with the second channel 414.

[0059] After one of the swing arms 421 on the movable block 42 forms a guide channel 422 with the first side wall 415, the steel ball 12 can enter the guide channel 422 and enter the first material channel 413 after hitting another swing arm 421 on the movable block 42. After the movable block 42 stops rotating, one of the swing arms 421 on the movable block 42 can form a guide channel 422 with the second side wall 416 to guide the steel ball 12 to the second material channel 414. After the steel ball 12 hits the corresponding swing arm 421 on the movable block 42 and enters the second material channel 414 and the movable block 42 stops rotating, one of the swing arms 421 on the movable block 42 forms a guide channel 422 with the first side wall 415.

[0060] More specifically, there are three swing arms 421, which are evenly arranged on the movable block 42. Figure 6 and Figure 7 As shown, a swing arm 421 on the movable block 42 forms a guide channel 422 with the first side wall 415 on the right side. Since the resistance of the guide channel 422 in this direction is small, the steel ball 12 flows out of the feed channel 411 and enters the guide channel 422. Under the guidance of the guide channel 422, it hits the swing arm 421 blocking the front of the steel ball 12. The movable block 42 rotates counterclockwise, and the steel ball 12 enters the first feed channel 413. After the movable block 42 stops rotating, a swing arm 421 on the movable block 42 and the second side wall 416 form a guide channel 422. Figure 8 and Fig. 9 As shown, the second steel ball 12 flows out of the feed channel 411 and enters the guide channel 422. Under the guidance of the guide channel 422, it hits the swing arm 421 blocking the front of the steel ball 12. The movable block 42 rotates clockwise, and the steel ball 12 enters the second material channel 414. After the movable block 42 stops, a swing arm 421 on the movable block 42 and the first side wall 415 form a guide channel 422, so that the third steel ball 12 can be guided into the first material channel 413.

[0061] In this embodiment, the steel ball diverter device 4 is installed at the outlet of the steel ball conveying device 3. After the steel ball conveying device 3 delivers the steel balls 12, the steel ball diverter device 4 distributes the steel balls 12 to the two discharge channels 412 in sequence. There is no need to respectively set up a steel ball conveying device 3 for each oil circuit process hole 11, which is conducive to cost saving.

[0062] Of course, in other embodiments, the diversion structure can also be baffles respectively arranged at the entrance of each discharge channel 412 , and the steel balls 12 in the discharge channel 412 can flow into one of the discharge channels 412 by controlling the cylinder to open one baffle at a time.

[0063] Furthermore, if Fig.10 and Fig.11 As shown, the steel ball conveying device 3 includes a turntable 31, a turntable driving device 32 and a turntable cover plate 33. The turntable 31 is connected to the output end of the turntable driving device 32 to drive the turntable 31 to rotate through the turntable driving device 32. Specifically, the turntable driving device 32 is a motor, more specifically a low-speed motor. At least two steel ball grooves 311 are arranged on the turntable 31 on a preset circumference line with its rotation center line as the center of the circle, and the turntable cover plate 33 is provided with a turntable outlet 332 connected to the inlet of the feed channel 411 and a turntable inlet 331 connected to the outlet of the steel ball silo 2. Each steel ball groove 311 can be rotated to the turntable outlet 332 and the turntable inlet 331 in sequence to enter and exit the corresponding steel ball groove 311, and when rotating to other positions, the steel ball groove 311 is blocked by the turntable cover plate 33.

[0064] In this embodiment, the steel balls 12 in the steel ball silo 2 can be transmitted to subsequent equipment one by one in an orderly manner through the transmission of the turntable 31, which is beneficial to improving the transmission efficiency.

[0065] Furthermore, the rotation centerline of the turntable 31 is set horizontally, and the turntable outlet 332 is set above the turntable inlet 331. The turntable outlet 332 is connected to the feed channel 411 through the inclined transition channel 35. The high end of the transition channel 35 is connected to the turntable outlet 332 and the low end is connected to the inlet of the feed channel 411.

[0066] Specifically, the motor support plate 34 and the turntable cover plate 33 are respectively arranged at the front and rear sides of the turntable 31, and the turntable drive device 32 is installed on the motor support plate 34. In addition, the turntable 31 has two steel ball grooves 311 with an interval of 180 degrees. When one steel ball 12 enters the lower steel ball groove 311, the other steel ball 12 flows out from the upper steel ball groove 311.

[0067] Specifically, the bottom plate 21 of the steel ball silo 2 is an inclined surface and its lower end surface is connected to the turntable cover 33 and is located below the turntable inlet 331. The steel balls 12 in the steel ball silo 2 can directly flow into the turntable inlet 331 under the action of gravity.

[0068] When in use, the steel balls 12 are placed in the steel ball silo 2. After one of the steel ball grooves 311 on the turntable 31 rotates to the bottom, the steel balls 12 enter the steel ball groove 311 from the outlet of the steel ball silo 2. After the turntable driving device 32 drives the turntable 31 to rotate 180°, the steel balls 12 in the steel ball silo 2 enter the transition channel 35 through the turntable outlet 332, and the steel balls 12 then enter the feed channel 411 under the action of their own weight.

[0069] In this embodiment, by placing the turntable 31 upright, the steel balls 12 can be transferred by utilizing the gravity of the steel balls 12 , which is beneficial to saving energy.

[0070] Furthermore, the press-fitting module also includes a press-fitting platform 6 , on which a fixture is arranged, so that there is no need to manually fix the crankshaft 1 , and the press-fitting efficiency of the steel ball 12 can be further improved.

[0071] Furthermore, a V-shaped groove is provided on the top of the press-fitting platform 6, and the fixture includes a limit block 61 and a material ejection driving device 62, and specifically, the material ejection driving device 62 is a cylinder. The limit block 61 and the material ejection driving device 62 are respectively provided at both ends of the V-shaped groove. Specifically, the limit block 61 is provided at one side opening of the V-shaped groove, and the output end of the material ejection driving device 62 can move toward or away from the limit block 61 through the other side opening of the V-shaped groove.

[0072] At this time, the crankshaft 1 can be placed on the V-groove with its axis centerline horizontal, and the crankshaft 1 can be pressed onto the limit block 61 by the push-up drive device 62. The two inclined sides of the V-groove, the push-up drive device 62 and the limit block 61 can reliably position the crankshaft 1 on all sides in the horizontal direction to ensure the accurate position of the crankshaft 1. Accordingly, the inlets of the oil circuit process holes 11 of the crankshaft 1 are located on the side of the crankshaft 1, specifically on the same pressing plane, and the steel ball pressing devices 5 are correspondingly arranged in sequence on the horizontal plane, so that the crankshaft oil circuit sealing device constitutes a horizontal pressing device.

[0073] Further, a detection switch is provided at the outlet of the discharge channel 412 to detect whether the steel ball 12 passes through, and the detection switch is communicatively connected to the control device. By providing the detection switch, it is detected whether the steel ball 12 is delivered in place to avoid pressure leakage.

[0074] Furthermore, the output end of the steel ball press-fitting device 5 is a press rod 51. Specifically, the press rod 51 includes a dedicated fixing sleeve, in which a press rivet head is installed, which is simple and easy to replace. A displacement sensor and a pressure sensor are arranged on the press rod 51. The displacement sensor, the pressure sensor and the steel ball press-fitting device 5 are communicatively connected to the control device.

[0075] In this embodiment, the pressure sensor can obtain the pressure curve of the pressure rod 51 and record the pressure information of each set of steel balls 12 of the crankshaft 1. It can collect and record the pressure information of each steel ball 12 on each crankshaft 1 during riveting, and then synthesize the pressure-displacement curve with the displacement information collected by the displacement sensor, make a clear record of the crankshaft 1 gear pressing data, and store it in the memory, so as to facilitate the search of the steel ball data of each set of crankshafts 1 and determine whether the steel ball 12 is pressed tightly.

[0076] Furthermore, the crankshaft oil circuit plugging device also includes a loading module 7, a unloading module 8 and a workpiece conveying device 9. The output end of the workpiece conveying device 9 moves in turn above the loading module 7, the press-fitting module and the unloading module 8. Through the arrangement of the workpiece conveying device 9, the loading module 7 and the unloading module 8, the crankshaft 1 can be automatically loaded, the steel ball 12 is pressed, the unloading and the transmission between the modules can be realized, and the efficiency of the press-fitting process can be further improved.

[0077] Furthermore, the loading module 7, the pressing module and the unloading module 8 are arranged linearly in the horizontal direction, specifically arranged in sequence along the horizontal X direction. The workpiece conveying device 9 includes a workpiece linear driving device 91, a workpiece lifting driving device 92 connected to the output end of the workpiece linear driving device 91, and a pick-up mechanism 93 provided at the output end of the workpiece lifting driving device 92. The workpiece linear driving device 91 is used to drive the workpiece lifting driving device 92 and the pick-up mechanism 93 to move above the loading module 7, the pressing module and the unloading module 8.

[0078] Specifically, the workpiece conveying device 9 is a truss robot. The workpiece linear drive device 91 is an X-axis horizontal push cylinder whose output end moves in the horizontal X direction, and the workpiece lifting drive device 92 is a Z-axis servo motor that moves in the vertical Z direction, which is connected to the pick-up mechanism 93 through a gear rack transmission mechanism. In addition, the housing of the Z-axis servo motor is slidably connected to the X-direction linear guide rail 94 to guide the workpiece lifting drive device 92 and the pick-up mechanism 93 in the X direction.

[0079] In addition, if Figure 4 As shown, in the arrangement direction of the loading module 7, the pressing module and the unloading module 8, the loading module 7 is arranged between the loading conveyor belt 71 and the pressing module, and the unloading module 8 is arranged between the unloading conveyor belt 81 and the pressing module.

[0080] Specifically, the pick-up mechanism 93 is a gripper, including two gripper cylinders and grippers respectively connected to each gripper cylinder. The two grippers are driven by the two gripper cylinders to move closer or farther away, thereby achieving the gripping and releasing of the crankshaft 1. In addition, the output end of the workpiece lifting drive device 92 is provided with four grippers sequentially arranged along the X direction. When in use, three of the pick-up mechanisms 93 can be respectively located above the loading module 7, the pressing module and the unloading module 8, and another pick-up mechanism 93 is located above the loading conveyor belt 71 or the unloading conveyor belt 81, so that the four pick-up mechanisms 93 can perform pick-up and unloading operations at different workstations, realize the automatic conversion of loading and unloading, further improve the work efficiency, and the automatic loading of the crankshaft 1 and the automatic feeding of the steel ball 12 can be performed synchronously, which can save time.

[0081] In this embodiment, a workpiece linear drive device 91 capable of bidirectionally driving the workpiece is used to replace manual handling, thereby realizing automatic loading and unloading of the crankshaft 1 and automatic handling of the crankshaft 1 between various workstations, thereby reducing labor intensity.

[0082] The crankshaft oil circuit blocking device provided in this embodiment has the following working principle:

[0083] Loading process: the Z-axis servo motor moves downward and into position, the gripper clamps the crankshaft 1, the gripper moves upward and into position, the X-axis lateral push cylinder pushes forward, so that each gripper moves forward one station and into position, the Z-axis servo motor moves downward and into position, the gripper is released, and each crankshaft 1 is transferred to its next adjacent station, and the crankshafts 1 of the loading conveyor belt 71, the loading module 7, the pressing module and the unloading module 8 are moved forward one station in turn. One loading process can realize the installation and movement of the crankshafts 1 of three stations at one time, which is convenient, fast and efficient. Each crankshaft 1 performs corresponding operations at the corresponding station, and the Z-axis servo motor reverses to make the gripper return along the Z direction and into position, and the X-axis lateral push cylinder retreats, waiting for the signal to complete the next cycle;

[0084] Press-fitting process of steel ball 12: In the press-fitting module, crankshaft 1 is installed on the fixture, and steel ball 12 is transported to the inlet of each oil process hole 11 by steel ball conveying device 3 and steel ball diverter device 4. Steel ball press-fitting device 5 feeds forward, and after conveying steel ball 12 to the designated position in oil process hole 11, it maintains pressure for a certain period of time to complete the press riveting process of steel ball 12. After the press riveting is completed, the pressure rod 51 of steel ball press-fitting device 5 returns to its original position, the press-fitting process is completed, and the signal is waited for the next cycle.

[0085] The crankshaft oil circuit plugging device in this embodiment makes full use of the mechanical principle design to automatically feed the steel balls 12 and orderly deliver them to the press-fitting positions at both ends of the crankshaft 1, replacing manual installation. The detection sensor of the press-fitting module detects whether the steel balls 12 are delivered to the right position, replacing manual detection. The truss manipulator, the loading module 7, the unloading module 8 and the steel ball conveying device 3 are used to form an automatic machine tool, and then through the conveyor belt, a whole crankshaft 1 steel ball 12 press-fitting automatic production line is formed, which improves production efficiency and reduces the labor of manual handling of the crankshaft 1.
