Description

Technical Field

[0001] The utility model relates to the technical field of parts assembly, in particular to a turning assembly device for shaft parts. Background Art

[0002] The assembly process is the last link in the production cycle of the industrial field, and it is also the most critical link. Improper assembly can easily cause safety accidents and economic losses. An effective and fast assembly method and device are of great significance to production. Shaft parts are mainly used in mechanical products. The assembly of shaft parts is a more critical part of mechanical products. The efficiency of the assembly determines the length of the production cycle of the mechanical product, and the quality of the assembly determines the service life of the mechanical product. Therefore, how to achieve efficient and high-quality assembly of shaft parts is the key to the production of mechanical products. Shaft parts are mainly used in conjunction with assembly holes on the workpiece. The current mainstream method of assembling shaft parts is manual knocking. This method has certain risks. Improper operation by the operator is prone to safety accidents, and the shaft hole is seriously damaged. Improper assembly of the shaft hole in the machine will seriously affect the shaft hole connection and damage the machine.

[0003] However, for example, Chinese utility model patent CN203622278U discloses a shaft parts assembly device, which connects to the workpiece via a guide rail and a slider to ensure that the two workpieces are in the same straight line, then connects the shaft to one end of the workpiece, and adjusts the distance between the two workpieces by sliding the slider to connect the shaft to the two workpieces. However, this method cannot assemble large shafts and has a narrow scope of application. For example, Chinese invention patent application CN107443297A discloses a large shaft parts assembly tool, the main principle of which is to place the shaft parts on a support frame, adjust the position of the support frame to adjust the position of the shaft parts, and finally apply external force to assemble the shaft parts to the workpiece. However, this method has low adjustment accuracy, low assembly quality and efficiency, and still requires the use of external force to complete the assembly.

[0004] In summary, the existing shaft parts assembly device has a narrow scope of application, low assembly quality and assembly efficiency, and can no longer meet the assembly needs of shaft parts in mechanical production. Utility Model Content

[0029] like Figure 1 and Figure 2As shown, the flipping assembly device for shaft parts of this embodiment includes a limit component 100, a flipping component 200, a translation component 300, a visual detection component 400 and a control component 500. The limit component 100 is arranged on the flipping component 200 and is used to limit the workpiece and the shaft parts respectively. The flipping component 200 is arranged on the translation end of the translation component 300 and is used to flip the workpiece from a horizontal assembly state to a vertical assembly state. The translation component 300 is used to drive the flipping component 200 to move horizontally. The visual detection component 400 is arranged on the limit component 100 and is used to image detect the centering position of the workpiece and the shaft parts. The control component 500 is respectively connected to the flipping component 200, the translation component 300 and the visual detection component 400 and is used to control the flipping component 200, the translation component 300 and the visual detection component 400 to work in coordination so that the workpiece and the shaft parts are vertically centered. Specifically, the shaft parts flipping assembly device of the present invention first arranges the workpiece to be assembled horizontally on the flipping component 200, and ensures that the workpiece is assembled reliably through the limit component 100, and then the control component 500 controls the flipping component 200 to work, so as to flip the workpiece from the horizontal assembly state to the vertical assembly state, and arranges the assembly holes on the workpiece vertically, and then the shaft parts to be assembled are lifted above the assembly holes of the workpiece, so as to detect the centering position of the workpiece and the shaft parts through the image of the visual detection component 400, and finally the control component 500 controls the translation component 300 to translate the flipping component 200, so that the assembly holes of the workpiece on the flipping component 200 and the shaft parts are accurately aligned vertically, and then the shaft parts fall under the action of gravity to be reliably assembled on the workpiece, and the shaft parts are limited by the limit component 100 to prevent the shaft parts from falling. The parts and the flip assembly 200 or the translation assembly 300 directly collide and wear. In this solution, the control assembly 500 controls the flip assembly 200, the translation assembly 300 and the visual inspection assembly 400 to work together to accurately align the workpiece and the shaft parts vertically. The limit assembly 100 reliably fixes the workpiece and prevents the shaft parts from colliding and wearing. Compared with the existing technology, the automatic assembly of the shaft parts is realized, and the assembly efficiency is high. The visual inspection assembly 400 and the translation assembly 300 ensure the centering assembly of the shaft hole, which greatly reduces the assembly error and improves the assembly quality. At the same time, the dead weight of the shaft parts is used for assembly, which causes less damage to the workpiece and the shaft parts. In addition, under the action of the limit assembly 100, the assembly process can be applied to the assembly of workpieces and shaft parts of different specifications. It has a wide range of applications and strong practicality, and is suitable for widespread promotion and application.

Specifically, the first translation member 310 drives the second translation member 320 to move horizontally in the horizontal plane, and then the second translation member 320 drives the flip assembly 200 to move horizontally in the horizontal plane. Since the translation direction of the translation end on the first translation member 310 and the translation direction of the translation end on the second translation member 320 are orthogonally arranged in the horizontal plane, the flip assembly 200 can be translated to any position in the horizontal plane under the action of the first translation member 310 and the second translation member 320, ensuring that the workpiece and shaft parts can be accurately aligned, and the orthogonal arrangement also facilitates the establishment of a translation coordinate system, thereby improving the translation accuracy and further improving the assembly quality of the workpiece and shaft parts.

Sufficient driving force is ensured by the plurality of second sliding drive members 324, and the movement direction is ensured to be accurate due to the mutual interference of the plurality of second sliding drive members 324, thereby realizing precise adjustment of the horizontal position of the flip assembly 200, thereby improving the centering accuracy.

[0033] like Figure 3 As shown, in this embodiment, the flip assembly 200 includes a flip base 210 fixedly mounted on the translational end of the second translating member 320, a flip frame 220 hingedly connected to the flip base 210 for supporting the workpiece, and a flip driver 230 fixedly mounted on the translational end of the second translating member 320 and hingedly connected at its telescopic end to the flip frame 220 for driving the flip frame 220 to flip relative to the flip base 210. Specifically, the flip frame 220 is mounted on the flip base 210. When the workpiece is assembled onto the flip frame 220, the telescopic end of the flip driver 230 extends to drive the flip frame 220 to flip relative to the flip base 210 until the workpiece is in a vertically assembled state. Optionally, the flip base 210 and the flip driver 230 are fixedly mounted on the second sliding plate 323. Optionally, the flip driver 230 is one of an oil cylinder, a pneumatic cylinder, and an electric push rod.

Sufficient driving force is provided by the multiple flip driving members 230, and the rotation direction of the flip frame 220 is ensured to be accurate under the mutual interference of the multiple flip driving members 230.

[0034] like Figure 3As shown, in this embodiment, the flip assembly 200 further includes support columns 240 disposed on the flip base 210 for supporting the flip frame 220 during workpiece installation. Specifically, when the workpiece is installed, the support columns 240 support the flip frame 220, thereby ensuring a horizontal arrangement of the support frame and facilitating stable placement of the workpiece on the flip frame 220. Optionally, a plurality of support columns 240 may be provided, with the plurality of support columns 240 spaced apart on the flip base 210 to provide reliable support for the flip frame 220.

[0035] like Figure 3 and Figure 4 As shown, in this embodiment, the limiting assembly 100 includes a first limiting member 110 disposed on the turning frame 220 for limiting the position of the workpiece, and a second limiting member 120 disposed on the turning assembly 200 for being disposed below the assembly hole of the workpiece to vertically limit the position of the shaft-like components. Specifically, after the workpiece is placed on the turning frame 220, the first limiting member 110 limits the position of the workpiece to ensure reliable assembly of the workpiece, while the second limiting member 120, disposed below the assembly hole of the workpiece, vertically limits the position of the shaft-like components to prevent the shaft-like components from colliding and wearing against the turning assembly 200 or the translation assembly 300 under their own weight. Optionally, the second limiting member 120 is annular. Optionally, the second limiting member 120 is disposed on the workpiece. Optionally, the second limiting member 120 is disposed on the turning assembly 200. Optionally, the second limiting member 120 is disposed on the translation assembly 300.

[0036] like Figure 3 As shown, in this embodiment, the first limiting member 110 includes a horizontal limiting structure 111 disposed on the turning frame 220 for horizontally limiting the workpiece, and a rotation limiting structure 112 disposed on the turning frame 220 for rotationally limiting the workpiece. Specifically, after the workpiece is placed on the turning frame 220, the horizontal limiting structure 111 is used to limit the workpiece horizontally, and then the rotation limiting structure 112 is used to limit the workpiece rotationally, so that the workpiece is securely fixed on the turning frame 220. Optionally, the horizontal limiting structure 111 includes a limiting post detachably disposed on the turning frame 220 for abutting and limiting the first end face of the workpiece in the horizontal direction, a mounting post disposed on the turning frame 220, and a limiting bolt threadedly connected to the mounting post for abutting and limiting the second end face of the workpiece in the horizontal direction, wherein the mounting post is provided with a limiting hole threadedly connected to the limiting bolt. Optionally, the rotation limiting structure 112 includes two limiting plates spaced apart on the flip frame 220 and a limiting pin passing through the two limiting plates for passing through the workpiece. The limiting pin is installed through the two limiting plates so as to pass through the limiting hole on the workpiece through the limiting pin to achieve rotation limiting of the workpiece.

[0037] like Figure 4As shown, in this embodiment, the visual inspection component 400 includes a camera 410 disposed on the second stopper 120 for photographing and transmitting images of the workpiece and the shaft-like parts, and a central processor 420 electrically connected to the camera 410 and the control component 500, respectively, for receiving and processing the images and transmitting the processing results to the control component 500. Optionally, the camera 410 is a CCD camera. Specifically, a CCD camera is mounted at the center of the second stopper 120 and directly below the assembly hole of the workpiece, so that the camera 410 and the assembly hole of the workpiece are coaxially arranged. The CCD is composed of a large number of pixels, each corresponding to a charge sensor, which can record the light intensity information corresponding to each pixel. The light intensity information recorded by the CCD camera is transmitted to the central processor 420. Based on the light intensity information, the central processor 420 can extract the edge of the assembly hole through image processing. The center of the assembly hole can be calculated based on the edge points of the assembly hole. The shaft part is hoisted above the assembly hole, and the edge of the shaft part is extracted based on the light intensity information. The center of the shaft part is then calculated. The center of the shaft part is then compared with the center of the assembly hole to calculate the difference. The difference is then converted into a propulsion pressure and speed and transmitted to the control component 500. The control component 500 controls the horizontal movement of the translation component 300 to accurately align the assembly hole and the shaft part to ensure assembly quality. It should be understood that the specific structure of the central processor 420 and the CCD camera is well known to those skilled in the art and will not be described in detail here.

[0038] like Figure 4As shown, in this embodiment, the control assembly 500 includes a translation sensor disposed on the translation assembly 300, a flip sensor disposed on the flip assembly 200, a control driver connected to the translation assembly 300 and the flip assembly 200, respectively, and a controller electrically connected to the translation sensor, the flip sensor, the control driver, and the visual detection assembly 400. Optionally, the first sliding driver 314, the second sliding driver 324, and the flip driver 230 are all hydraulic cylinders, the control driver includes a hydraulic station and a servo valve, two translation sensors are provided, one disposed on the first sliding driver 314 and the second sliding driver 324, respectively, and three servo valves are provided, one connected to the first sliding driver 314, the second sliding driver 324, and the flip driver 230, respectively. Specifically, the central processor 420 collects the displacement data of the displacement sensors in the first sliding drive 314 and the second sliding drive 324, and records the corresponding stroke and pressure. Then, the data is collected based on the visual detection component 400 to calculate the coordinate difference between the shaft part and the center of the assembly hole, and the coordinate difference is converted into a displacement. The propulsion pressure and propulsion speed of the first sliding drive 314 and the second sliding drive 324 are calculated based on the displacement, and the signal is transmitted to the controller. The controller transmits the signal to each servo valve. The servo valve controls the lateral displacement, vertical displacement and flipping of the workpiece by controlling the hydraulic oil pressure and flow rate of the hydraulic station, thereby achieving the precise alignment of the shaft part and the assembly hole. Optionally, the controller is a PLC controller. It should be understood that the specific structure of the PLC controller belongs to the well-known technology of those skilled in the art.

[0039] like Figures 1-4As shown, the working process of the shaft parts flip assembly device of this embodiment is as follows: place the flip frame 220 horizontally on the support column 240, lift the workpiece to the flip frame 220 and place it stably, use the horizontal limiting structure 111 and the rotation limiting structure 112 to limit the workpiece in multiple directions, align the assembly hole of the workpiece through the second limiting member 120, install the CCD camera to the center of the second limiting member 120, connect the wires and hydraulic pipelines of each component, start the hydraulic station, and extend the telescopic end of the flip drive member 230. As the telescopic end of the flip drive member 230 extends, the flip frame 220 rotates relative to the flip base 210 until the flip frame 220 rotates 90° with the workpiece, and the flip drive member 230 is no longer working. At this time, the orientation of the assembly hole on the workpiece is adjusted from horizontal to vertical. The shaft is then hoisted above the assembly hole. The CCD camera uses light intensity information to identify the edges of the assembly hole and the shaft, and transmits this light intensity information to the central processor 420. The central processor 420 uses a built-in algorithm to calculate the displacement required for shaft-hole alignment. This displacement is transmitted to the controller as pressure and velocity signals, controlling the opening of the servo valve, and thus controlling the extension and retraction of the telescopic ends of the first and second sliding drive members 314 and 324 to achieve precise alignment between the assembly hole and the shaft. After alignment, the shaft is slowly lowered. Due to the inherent gravity of the shaft, the shaft is generally lowered without the need for additional power. Once the shaft is in place, the second stopper 120 limits further movement of the shaft. This shaft is assembled and the next shaft can be assembled. After the shaft is assembled, the telescopic end of the tilting drive 230 retracts, adjusting the tilting frame 220 and the workpiece to a horizontal position. The support base is then used to support the entire assembly process. The only manual operation required during the entire assembly process is to secure the workpiece in a horizontal position; the subsequent assembly process is automated.

[0040] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
