Description

[0002] As competition in the automotive industry intensifies, the design of engines is constantly reducing costs and improving efficiency through integration and modularization. The existing camshaft installation method is mainly to first install the camshaft on the cylinder head, and then install it separately through the shaft covers of each gear. There is also a positioning structure on each shaft cover, and it is also necessary to engrave a sequence mark on the shaft cover, resulting in a large number of parts and complex assembly. At present, the disassembly and assembly of the camshaft and the shaft cover still need to be done manually, that is, the bolts are manually removed and the shaft cover is removed, and then the camshaft is manually taken and installed on the cylinder head, and finally the shaft cover is fixed to the camshaft to complete the installation of the camshaft. This disassembly and assembly method takes a long time and has high labor intensity, resulting in low assembly efficiency.

[0054] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific embodiments of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings, are constructed and operated in a specific direction, and are only for the convenience of describing the present technical solution, rather than indicating that the device or element referred to must have a specific direction, and therefore cannot be understood as a limitation to the present invention.

[0055] It should also be noted that, unless otherwise clearly specified and limited, the terms such as "installed", "connected", "connected", "fixed", "set" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. When an element is referred to as being "on" or "under" another element, the element can be "directly" or "indirectly" located on the other element, or there may be one or more intermediate elements. The terms "first", "second", "third", etc. are only for the convenience of describing the present technical solution, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances.

[0056] In the following description, specific details such as specific system structures, technologies, etc. are provided for the purpose of illustration rather than limitation, so as to provide a thorough understanding of the embodiments of the present invention. However, it should be clear to those skilled in the art that the present invention may be implemented in other embodiments without these specific details. In other cases, detailed descriptions of well-known systems, devices, circuits, and methods are omitted to prevent unnecessary details from obstructing the description of the present invention.

[0057] At present, the specific process of disassembling the camshaft is: manually remove the bolts and remove the shaft cover, and then manually take the camshaft out of the shaft chamber of the engine to complete the disassembly of the camshaft. Correspondingly, the specific process of installing the camshaft is: manually put the camshaft into the shaft chamber of the engine, and then press the shaft cover against the camshaft and tighten the bolts to complete the installation of the camshaft. However, whether it is the disassembly or installation of the camshaft, it is conducive to manual operation, which makes the time required longer and the labor intensity high, resulting in low assembly efficiency. At the same time, it is also easy for foreign matter to stick to the shaft diameter of the camshaft, thereby resulting in poor engine production quality. To this end, the present application provides an automatic disassembly and assembly equipment that can realize automated assembly, can effectively reduce labor intensity, improve assembly efficiency, and can effectively eliminate the problem of poor quality caused by manual installation.

[0058] like Figures 1 to 3As shown, an embodiment of the present invention provides an automatic disassembly and assembly device, which is used for disassembling and assembling a camshaft and axle cover of an engine. The automatic disassembly and assembly device includes a frame 10, a conveying device 20, a shaft cover disassembly and assembly device 30, and a camshaft disassembly and assembly device 40. The conveying device 20 is penetrated in the frame 10, and the shaft cover disassembly and assembly device 30 and the camshaft disassembly and assembly device 40 are both connected to the frame 10. The frame 10 can be made of aluminum alloy to ensure that the manufactured frame 10 has sufficient structural strength.

[0059] Specifically, the conveying device 20 is used to convey the engine to be disassembled and assembled along the first direction X, and a disassembly position A is provided on the conveying device 20; the shaft cover disassembly and assembly device 30 includes a first transplanting mechanism 32 and a first disassembly and assembly mechanism 31, the first transplanting mechanism 32 is arranged above the conveying device 20, and is used to drive the first disassembly and assembly mechanism 31 to move back and forth along the first direction X and temporarily stop at the disassembly and assembly position A, and the first disassembly and assembly mechanism 31 can move back and forth along the second direction Y to disassemble and assemble the shaft cover of the engine located at the disassembly and assembly position A; the camshaft disassembly and assembly device 40 includes a second transplanting mechanism 41 and a second disassembly and assembly mechanism 42, the second transplanting mechanism 41 is arranged above the conveying device 20, and is used to drive the second disassembly and assembly mechanism 42 to move back and forth along the third direction Z and temporarily stop at the disassembly and assembly position A, and the second disassembly and assembly mechanism 42 can move back and forth along the second direction Y to disassemble and assemble the camshaft of the engine located at the disassembly and assembly position A; wherein the first direction X, the second direction Y and the third direction Z are perpendicular to each other.

[0060] It should be noted that the "first direction X", "second direction Y" and "third direction Z" mentioned above are fictitious for the purpose of describing the relative positional relationship between the conveying device 20, the shaft cover disassembling device 30 and the camshaft disassembling device 40, and do not play a limiting role. Figure 1 , the “first direction X” can refer to Figure 1 The X direction in the “second direction Y” can refer to Figure 1 The Y direction in the “third direction Z” can refer to Figure 1 The Z direction in .

[0061] For example, the disassembly position A refers to the position for disassembling the shaft cover and camshaft of the engine, which can be determined according to the actual situation. For example, since the first disassembly mechanism 31 and the second disassembly mechanism 42 are used to disassemble the shaft cover and camshaft on the engine respectively, the disassembly position A needs to be set at the intersection of the stroke of the first disassembly mechanism 31 driven by the first transfer mechanism 32 and the stroke of the second disassembly mechanism 42 driven by the second transfer mechanism. Specifically in this embodiment, the disassembly position A is Figure 1 At point A in the middle.

[0062] The present application uses a conveying mechanism to convey the engine to be disassembled to the disassembly position A, and then uses the first transfer mechanism 32 to drive the first disassembly mechanism 31 to move back and forth along the first direction X, and uses the second transfer mechanism 41 to drive the second disassembly mechanism to move back and forth along the third direction Z, so that the first disassembly mechanism 31 and the second disassembly mechanism 42 can temporarily stop above the disassembly position A, and then move along the second direction Y to disassemble and assemble the shaft cover and the camshaft of the engine located at the disassembly position A respectively. Compared with the traditional manual operation method, automated assembly is realized, which can effectively reduce labor intensity, improve assembly efficiency, and effectively eliminate the problem of poor quality caused by manual installation.

[0063] It should be noted that the automatic disassembly and assembly device of the present application can not only automatically install the camshaft, but also automatically disassemble the camshaft. For ease of understanding, the following description will be given by taking the disassembly of the camshaft as an example, as follows:

[0064] The engine is placed in the conveying device 20, and is transferred to the disassembly position A driven by the conveying device 20, and then the first disassembly mechanism 31 is driven by the first transferring mechanism 32 to move along the first direction X, so that the first disassembly mechanism 31 moves to the disassembly position A and stops temporarily, and then the first disassembly mechanism 31 moves along the second direction Y to approach the engine for shaft cover disassembly, and clamps the shaft cover to be brought away from the disassembly position A, and then the second transferring mechanism 41 drives the second disassembly mechanism 42 to move along the third direction Z, so that the second disassembly mechanism 42 moves to the disassembly position A and stops temporarily, and then the second disassembly mechanism 42 moves along the second direction Y to approach the engine for camshaft disassembly, thereby completing the automatic disassembly of the camshaft without manual operation, which is beneficial to reducing labor intensity and improving production efficiency.

[0065] Please refer to Figures 4 to 6 In one embodiment, the first disassembly and assembly mechanism 31 includes a fixed plate 311, a first power member 312, a first mounting plate 313 and a plurality of shaft cover disassembly and assembly units 316, the fixed plate 311 is located between the conveying device 20 and the first transplanting mechanism 32; the first power member 312 is fixed on the fixed plate 311 and connected to the first transplanting mechanism 32; the first mounting plate 313 is located below the fixed plate 311, the output end of the first power member 312 passes through the fixed plate 311 and is connected to the first mounting plate 313 to drive the first mounting plate 313 to reciprocate along the second direction Y, and a plurality of shaft cover disassembly and assembly units 316 are connected to the first mounting plate 313 for disassembling and assembling the shaft cover of the engine.

[0066] For example, the first power member 312 may be a cylinder, and the extension and contraction of the cylinder piston rod may be used to drive the first mounting plate 313 to move back and forth along the second direction Y, thereby driving the plurality of shaft cover disassembly units 316 to approach or move away from the engine at the disassembly position A, so as to facilitate subsequent disassembly and assembly of the shaft covers. The above is only an example and is not limited thereto.

[0067] Please refer to Figure 5 and Figure 6 Since the sizes of the shaft caps used in different models are different, in order to be applicable to the disassembly and assembly of shaft caps of different models, in other embodiments, the surface of the first mounting plate 313 facing the fixed plate 311 is provided with a first slide rail 314 extending along the first direction X, and the first slide rail 314 is slidably connected with the first slider 315. Each shaft cap disassembly and assembly unit 316 includes a connecting bar and two first clamps symmetrical to the center line of the first mounting plate 313. The connecting bar is provided on the first mounting plate 313 along the third direction Z and connected to the first slider 315. The first clamp is provided below the first mounting plate 313 and connected to the connecting bar. The first clamp is used to disassemble and assemble the shaft cap on the engine. The driving unit 317 includes a driving member 3171 and a driving shaft 3172. The driving member 3171 is mounted on the first mounting plate 313, and the output end of the driving member 3171 is connected to one end of the driving shaft 3172. The driving shaft 3172 is rotatably arranged on the inner side of the slide rail along the first direction X. The connecting plate 3161 is transmission-connected to the driving shaft 3172 through the first connecting seat so that the connecting plate 3161 can be driven to move back and forth along the first direction X.

[0068] That is to say, when disassembling and assembling shaft covers of different sizes, the driving member 3171 is used to drive the driving shaft 3172 to rotate, so that the first connecting seat is driven to slide on the driving shaft 3172. Since the connecting plate 3161 is connected to the first connecting seat, the connecting plate 3161 can be driven to move along the first direction X, thereby driving the first clamp connected to the connecting plate 3161 to move, thereby adjusting the distance between two adjacent shaft cover disassembly and assembly units 316, which can be suitable for disassembling and assembling shaft covers of different sizes, and has a wider applicability. At the same time, a first slide rail 314 is set on the first mounting plate 313, and a first slider 315 is slidably connected to the first slide rail 314. The first slider 315 is connected to the connecting plate 3161, so that the connecting plate 3161 can drive the first clamp to move along a predetermined direction.

[0069] Specifically, the first clamp includes a first clamping cylinder 3162, an electric screwdriver 3164, and first clamping claws 3163 located on both sides of the first clamping cylinder 3162. The top of the cylinder body of the first clamping cylinder 3162 is connected to the connecting plate 3161. The first clamping cylinder 3162 is connected to the first clamping claws 3163 to drive the two first clamping claws 3163 to open or close. The electric screwdriver 3164 is installed at the bottom of the cylinder body and is used to loosen or tighten the bolts on the shaft cover. In other words, when disassembling the shaft cover, the electric screwdriver 3164 is used to loosen the bolts on the shaft cover, and then the first clamping cylinder 3162 is used to drive the first clamping claws 3163 to open to clamp the shaft cover. Then, the first power member 312 is used to drive the first mounting plate 313 to reciprocate along the second direction Y, so that the clamped shaft cover is lifted upward and away from the disassembly position A, thereby completing the automatic disassembly of the shaft cover without the need for manual assistance, which is conducive to reducing labor intensity.

[0070] Please refer to Figure 5 and Figure 6 In one embodiment, the first transplanting mechanism 32 includes a first slide 321, a first drive motor 322, a rack 324 and a second slide rail 326, the first slide 321 is connected to the top of the first power member 312; the first drive motor 322 is installed on the first slide 321, and the output end of the first drive motor 322 is connected to the active tooth 323; the rack 324 is arranged above the conveying device 20 along the first direction X, and the tooth portion of the rack 324 is meshed with the active tooth 323; the second slide rail 326 is arranged on the outer side of the rack 324 along the first direction X, and the second slide rail 326 is slidably connected with the second slider 325, and the second slider 325 is connected to the lower surface of the first slide 321. That is to say, the first driving motor 322 drives the active gear 323 to rotate, so that the first slide plate 321 is driven to move along the extension direction of the rack 324, thereby driving the first disassembly and assembly mechanism 31 to move back and forth along the first direction X, so as to accurately move the first disassembly and assembly mechanism 31 to above the disassembly and assembly position A, so that the first disassembly and assembly mechanism 31 can remove the shaft cover of the engine located at the disassembly and assembly position A.

[0071] Please refer to Figure 7 and Figure 8, please refer to the figure. In one embodiment, the second disassembly and assembly mechanism 42 includes a second slide plate 421, a support plate 422, a second power member 423, a third power member 424, a second mounting plate 425 and a camshaft disassembly and assembly unit 426. The second slide plate 421 is connected to the second transplanting mechanism 41 so as to be able to move back and forth along the third direction Z; the support plate 422 is slidably connected to the second slide plate 421. The second power member 423 is fixed on the second slide plate 421, and the output end of the second power member 423 is connected to the top of the support plate 422 to drive the support plate 422 to move back and forth along the second direction Y; the third power member 424 is fixed on the support plate 422; the second mounting plate 425 is located below the support plate 422, and the output end of the third power member 424 passes through the support plate 422 and is connected to the second mounting plate 425 to drive the second mounting plate 425 to move back and forth along the second direction Y. The camshaft disassembly and assembly unit 426 includes a second clamp 4261, which includes a second clamping cylinder 42611 and two second clamping jaws 42612. The second clamping cylinder 42611 is connected to the lower surface of the second mounting plate 425, and the two second clamping jaws 42612 are connected to the second clamping cylinder 42611 to drive the opening or closing of the two second clamping jaws 42612 through the second clamping cylinder 42611.

[0072] Exemplarily, the support plate 422 can be slidably connected to the second slide plate 421 in a manner that a slide rail and a slider cooperate with each other, that is, a fourth slide rail 428 is arranged on the second slide plate 421 along the second direction Y, and a fourth slider 429 is slidably connected to the fourth slide rail 428, and the fourth slider 429 is connected to the support plate 422.

[0073] Illustratively, after the second transplanting mechanism 41 moves the second disassembly and assembly mechanism 42 to above the disassembly and assembly position A, the second power member 423 drives the support plate 422 to move along the second direction Y, so as to drive the third power member 424 fixed on the support plate 422 and the second mounting plate 425 to approach the engine located at the disassembly and assembly device, and then drive the second clamping cylinder 42611 connected to the lower surface of the second mounting plate 425. At this time, the two second clamping jaws 42612 are in an open state under the action of the second clamping cylinder 42611. After the two second clamping jaws 42612 contact the camshaft, the second clamping cylinder 42611 drives the two second clamping jaws 42612 to close to clamp the camshaft on the engine. Finally, under the action of the third power member 424 and the second power member 423, the clamped camshaft is removed from the engine, thereby completing the automatic disassembly and assembly of the camshaft without manual operation, which is conducive to improving production efficiency. That is to say, the present application uses a secondary drive method to drive the second clamp 4261 to move back and forth along the second direction Y, that is: the first time is to use the second power member 423 to drive the support plate 422 to move, so as to drive the third power member 424, the second mounting plate 425 and the second clamp 4261 to move along the second direction Y, and the second time is to drive the second mounting plate 425 to move along the second direction Y by the third power member 424, so as to drive the second clamp 4261 to move, thereby ensuring that the second clamp 4261 can have a longer stroke, and can also ensure smoother operation and more stable clamping of the camshaft. In addition, the second power member 423 and the third power member 424 can both use cylinders, or can use power components that can achieve lifting in the prior art, without limitation.

[0074] Specifically, the camshaft disassembly and assembly unit 426 further includes a third clamp 4262 and a fourth clamp 4263 which are arranged at intervals on both sides of the second clamp 4261. The third clamp 4262, the fourth clamp 4263 and the second clamp 4261 are located on the same straight line, and the third clamp 4262 and the fourth clamp 4263 are both connected to the lower surface of the second mounting plate 425 for clamping the camshaft. In this way, by respectively clamping the middle and both ends of the camshaft using the second clamp 4261, the third clamp 4262 and the fourth clamp 4263, the camshaft is clamped more firmly to avoid the risk of falling during the process of disassembling and assembling the camshaft.

[0075] Please refer to Figure 8In one embodiment, the second disassembly and assembly mechanism 42 also includes a positioning assembly 427, which includes an elastic column 4272, a positioning plate 4271 and a positioning column 4273. The elastic column 4272 is located on the outside of the second clamp 4261, and the upper end of the elastic column 4272 is connected to the lower surface of the second mounting plate 425; the positioning plate 4271 is connected to the lower end of the elastic column 4272; the positioning column 4273 is installed at both ends of the positioning plate 4271 for positioning the engine. In this way, when the third power member 424 drives the second mounting plate 425 along the second direction Y to approach the disassembly position A of the engine, since the positioning plate 4271 is connected to the second mounting plate 425 through the elastic column 4272, the positioning plate 4271 moves along with the movement of the second mounting plate 425, thereby driving the positioning column 4273 connected to the positioning plate 4271 to approach the engine until the positioning column 4273 contacts the fixing fixture on which the engine is placed, thereby ensuring that the second clamp 4261, the third clamp 4262 and the fourth clamp 4263 connected to the lower surface of the second mounting plate 425 can accurately clamp the middle and both ends of the camshaft, thereby avoiding the failure to clamp due to the inability to align the camshaft.

[0076] Please refer to Figure 7 In one embodiment, the second transplanting mechanism 41 includes a third mounting plate 411 and a second drive motor 412. The third mounting plate 411 is arranged above the conveying device 20 along the third direction Z. A rotating rod 413 extends from the third mounting plate 411 along the third direction Z. A second connecting seat is connected to the transmission rod for transmission. The second connecting seat is connected to the back of the second slide plate 421. The second drive motor 412 is fixed to one end of the third mounting plate 411, and the output end of the second drive motor 412 is connected to one end of the transmission rod.

[0077] That is to say, when the second disassembly and assembly mechanism 42 is needed to cam the engine located at the disassembly and assembly position A, the second drive motor 412 is used to drive the rotating rod 413 to rotate, so as to drive the second connecting seat to move along the third direction Z, thereby driving the second slide plate 421 to move back and forth, so as to accurately move the second disassembly and assembly mechanism 42 to the top of the disassembly and assembly position A, so that the second disassembly and assembly mechanism 42 can disassemble the camshaft of the engine located at the disassembly and assembly position A.

[0078] Please refer to Fig. 9In one embodiment, two third slide rails 414 are further included. The two third slide rails 414 are fixed on the third mounting plate 411 along the third direction Z and are located outside the rotating rod 413. A third slider 415 is slidably connected to the third slide rails 414. The third slider 415 is connected to the back of the second slide plate 421. In this way, during the movement of the second slide plate 421, due to the action of the third slide rails 414 and the third slider 415, the accuracy and stability of the movement of the second slide plate 421 can be guaranteed.

[0079] Please refer to Fig.10 In one embodiment, the conveying device 20 includes a frame 21 and a grating assembly 23, and a plurality of conveying rollers 22 are spaced across the top surface of the frame 21. The plurality of conveying rollers 22 can be rotatably connected to the frame 21 by a motor drive, that is, adjacent conveying rollers 22 are connected by a transmission belt, and the output end of the motor is connected to one of the conveying rollers 22, so that the plurality of conveying rollers 22 are driven by the motor to rotate; the grating assembly 23 includes a first grating unit 231 and a second grating unit 232, and the first grating unit 231 and the second grating unit 232 are spaced apart on the outside of the frame 21, and the area defined between the first grating unit 231 and the second grating unit 232 is the disassembly position A.

[0080] Exemplarily, the engine to be disassembled is driven by the conveying roller 22. When the first grating unit 231 senses that an object has entered and transmits a signal to the controller, the controller appropriately controls the rotation speed of the conveying roller 22 to reduce the speed of conveying the engine until the second grating unit 232 senses the object. The conveying roller 22 stops running, so that the engine is accurately transported to the disassembly position A, ensuring that the subsequent first disassembly mechanism 31 and the second disassembly mechanism 42 can accurately disassemble the shaft cover and camshaft of the engine located at the disassembly position A.

[0081] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principles of the present invention. These improvements and substitutions should also be regarded as the scope of protection of the present invention.
