Description

Technical Field

[0001] The utility model relates to the technical field of crankshaft production, in particular to a deburring mechanism for crankshaft production. Background Technique

[0002] The crankshaft is the most important component in an engine. It bears the force transmitted by the connecting rod and converts it into torque, which is output through the crankshaft and drives other accessories on the engine to work. The crankshaft is jointly affected by the centrifugal force of the rotating mass, the gas inertia force that changes periodically, and the reciprocating inertia force, so that the crankshaft bears the action of bending and torsional loads.

[0003] During the production process of the crankshaft, there may be some protrusions or irregular edges on the crankshaft, which are called burrs. The existence of burrs may affect the quality and performance of the crankshaft, and may cause problems during subsequent processing and use. The presence of burrs on the crankshaft will affect the normal operation of equipment such as engines.

[0004] After retrieval, in a deburring device for general-purpose engine crankshaft production with the patent publication number CN218254265U, it is proposed that "the deburring device for general-purpose engine crankshaft production can deburr crankshafts of different sizes by setting an adjustment component, and at the same time, by setting two groups of deburring components, it can comprehensively deburr irregular crankshafts";

[0005] However, there are still certain deficiencies in the above scheme during actual use. During the deburring process of the crankshaft, the removed burr waste chips fly outwards, and there is no protective structure on the outside of the deburring device in the above scheme, resulting in the burr waste chips being easily ejected from the working area in an indefinite direction. The flying burr waste chips will pose a threat to the personal safety of the staff and cause pollution to the environment of the processing workshop, making the use safety of the deburring device relatively low. Content of the Utility Model

[0006] The utility model provides a deburring mechanism for crankshaft production to solve the problems in the background technique.

[0007] To achieve the above purpose, the utility model provides the following technical scheme: A deburring mechanism for crankshaft production, including a crankshaft body and a processing table. A fixing device, a cleaning device, and a lifting device are fixedly installed at the top of the processing table. The crankshaft body is located inside the fixing device, the cleaning device is located behind the fixing device, and a protective cover structure is fixedly installed at the movable end of the lifting device;

[0008] The lifting device includes a driving frame. An inner wall of the driving frame is rotationally connected with a driving turntable through a built-in motor. An eccentric wheel is fixedly installed on an outer side of the driving turntable. An outer side of the eccentric wheel is movably sleeved with a movable collar. A bottom end of the movable collar is fixedly installed with a connecting rod. A bottom end of the connecting rod extends to an outer side of the driving frame and is fixedly connected with a side end of a protective cover structure;

[0009] The protective cover structure includes a protective cover lid. A lifting door is slidably connected inside the protective cover lid.

[0010] Furthermore, the fixing device includes a first mounting seat and a second mounting seat. A bottom end of the first mounting seat is fixedly connected with a top end of a processing table. A bottom end of the second mounting seat is slidably connected with the top end of the processing table through a servo electric cylinder.

[0011] Furthermore, a clamping head is rotationally connected to inner walls of the first mounting seat and the second mounting seat through a servo motor and a rotating shaft. The clamping head is connected with a side end of a crankshaft body.

[0012] Furthermore, the cleaning device includes a linear motor. A cleaning brush is movably clamped to a movable end of the linear motor. The cleaning brush is located on an outer side of the crankshaft body.

[0013] Furthermore, a vertical rod is fixedly installed on an inner wall of the driving frame. A side end of the movable collar is slidably connected with a surface of the vertical rod.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4 , the present utility model discloses a deburring mechanism for crankshaft production, including a crankshaft body 1 and a processing table 2. A fixing device 3, a cleaning device 4, and a lifting device 5 are fixedly installed at the top end of the processing table 2. The crankshaft body 1 is located inside the fixing device 3. The cleaning device 4 is located behind the fixing device 3. A protective cover structure 6 is fixedly installed at the movable end of the lifting device 5.

[0023] The fixing device 3 includes a first mounting seat 301 and a second mounting seat 302. The bottom end of the first mounting seat 301 is fixedly connected to the top end of the processing table 2. The inner walls of the first mounting seat 301 and the second mounting seat 302 are rotatably connected with a clamping head 304 through a servo motor 303 and a rotating shaft. The clamping head 304 is connected to the side end of the crankshaft body 1. The bottom end of the second mounting seat 302 is slidably connected to the top end of the processing table 2 through a servo electric cylinder 305.

[0024] The working principles of the servo motor 303 and the servo electric cylinder 305 have been described in detail in a carbon fiber tube forming device with a patent publication number of CN221560723U, and will not be elaborated here.

[0025] The cleaning device 4 includes a linear motor 401. A cleaning brush 402 is movably clamped at the movable end of the linear motor 401. The cleaning brush 402 is located outside the crankshaft body 1.

[0026] The lifting device 5 includes a driving frame 501. The inner wall of the driving frame 501 is rotatably connected with a driving turntable 502 through a built-in motor. An eccentric wheel 503 is fixedly installed on the outer side of the driving turntable 502. An activity collar 504 is movably sleeved on the outer side of the eccentric wheel 503. A connecting rod 505 is fixedly installed at the bottom end of the activity collar 504. The bottom end of the connecting rod 505 extends to the outside of the driving frame 501 and is fixedly connected with the side end of the protective cover structure 6;

[0027] The protective cover structure 6 includes a protective cover 601. A lifting door 602 is slidably connected inside the protective cover 601.

[0028] By setting the lifting device 5 and the protective cover structure 6, the driving turntable 502 inside the driving frame 501 included in the lifting device 5 can promote the activity collar 504 to drive the protective cover structure 6 at the side end of the connecting rod 505 to adjust the height through the eccentric wheel 503, so that the protective cover 601 included in the protective cover structure 6 gradually covers the top of the processing table 2, making the protective cover 601 form a wrapped protective structure outside the fixing device 3 and the cleaning device 4, preventing the burr waste chips from flying out of the working area in an indefinite direction when the cleaning device 4 is working, providing protection for the personal safety of the staff and protecting the environment of the processing workshop.

[0029] Specifically, a vertical rod is fixedly installed on the inner wall of the driving frame 501. The side end of the activity collar 504 is slidably connected with the surface of the vertical rod.

[0030] In this implementation scheme, the vertical rod can be used to limit the movement track of the activity collar 504, so that the activity collar 504 can only slide along the direction of the vertical rod.

[0031] During use, first measure the length of the crankshaft body 1, and then adjust the distance between the first mounting seat 301 and the second mounting seat 302 according to this length, so that the servo electric cylinder 305 drives the second mounting seat 302 to displace, and then completes the subsequent adjustment of the interval between the first mounting seat 301 and the second mounting seat 302. Then connect the two ends of the crankshaft body 1 with the two clamping heads 304 respectively;

[0032] When the crankshaft body 1 needs to be rotated, start the servo motor 303, so that the servo motor 303 drives the clamping head 304 inside the first mounting seat 301 to rotate, and the clamping head 304 inside the first mounting seat 301 drives the crankshaft body 1 to rotate, so that the crankshaft body 1 can be comprehensively deburred;

[0033] After the crankshaft body 1 is fixed, start the lifting device 5, so that the built-in power supply inside the driving frame 501 drives the driving turntable 502 to rotate, and the driving turntable 502 drives the eccentric wheel 503 to perform a circular motion. Since the eccentric wheel 503 is located inside the movable collar 504 and is slidably connected to the inner wall of the movable collar 504, the relative position between the eccentric wheel 503 and the movable collar 504 will change during the movement, causing the eccentric wheel 503 to drive the movable collar 504 to perform a vertical movement on the front side of the driving turntable 502, so that the movable collar 504 drives the protective cover 601 to gradually descend through the connecting rod 505, prompting the bottom end of the protective cover 601 to gradually overlap with the top end of the processing table 2, so that the protective cover 601 gradually covers the fixing device 3 and the cleaning device 4 therein, and the protective cover 601 forms a wrapped protective structure outside the fixing device 3 and the cleaning device 4;

[0034] Subsequently, start the cleaning device 4, so that the movable end of the linear motor 401 drives the cleaning brush 402 to slide horizontally, prompting the cleaning brush 402 to clean the burrs on the crankshaft body 1.

[0035] In summary, for the deburring mechanism for crankshaft production, by setting the lifting device 5 and the protective cover structure 6, the driving turntable 502 inside the driving frame 501 included in the lifting device 5 can promote the movable collar 504 to drive the protective cover structure 6 at the side end of the connecting rod 505 to adjust the height through the eccentric wheel 503, prompting the protective cover 601 included in the protective cover structure 6 to gradually cover the top end of the processing table 2, so that the protective cover 601 forms a wrapped protective structure outside the fixing device 3 and the cleaning device 4, preventing the burr waste chips from flying out of the working area in an indefinite direction when the cleaning device 4 is working, providing protection for the personal safety of the staff and protecting the environment of the processing workshop.
