Description

Technical Field

[0001] This utility model relates to the field of motorcycle right crankcase manufacturing technology, and in particular to a right crankcase pressing device. Background Technology

[0002] The right crankcase is a crucial component of a motorcycle. Together with the left crankcase, it forms the sealed chamber of the engine, protecting core components such as the crankshaft, connecting rods, and bearings. This prevents oil leakage and the intrusion of external debris, ensuring the normal operation of the motorcycle engine. Currently, most right crankcases in conventional motorcycles are manufactured using die casting. This requires process holes to achieve proper casting, and after die casting, a plug needs to be pressed into these holes for sealing. Furthermore, to maintain pressure balance within the crankcase, a vent pipe is typically installed; and to guide oil flow, an oil guide pin is usually also installed. In some motorcycle models, both the vent pipe and oil guide pin are located in the right crankcase. Currently, the plugs, vent pipes, and oil guide pins are all manually hammered and pressed into the right crankcase by workers using hammering tools. This process is time-consuming, labor-intensive, and prone to damaging the surfaces of the components. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a right crankcase press-fitting device that can simultaneously press-fit a plug, vent pipe, and oil guide pin onto the right crankcase body, thereby improving production efficiency.

[0004] A right crankcase pressing device according to an embodiment of the present invention includes:

[0005] The positioning assembly includes a support platform and a positioning mechanism. The positioning mechanism is installed above the support platform and is used to position the right crankshaft housing.

[0006] The press assembly includes a first pressing mechanism, a second pressing mechanism, and a third pressing mechanism. The first pressing mechanism, the second pressing mechanism, and the third pressing mechanism are disposed on the side of the support platform and are spaced apart along the circumference of the support platform.

[0007] A right crankcase pressing device according to an embodiment of the present utility model has at least the following beneficial effects:

[0008] The press-fit assembly allows for the separate press-fitting of the plug, oil guide pin, and vent pipe into the right crankshaft housing, improving the press-fitting effect and eliminating the need for manual hammering, thus saving manpower and increasing press-fitting speed. A single press by the first, second, and third pressing mechanisms achieves the press-fitting of the plug, oil guide pin, and vent pipe, reducing the number of contacts between the press-fitting device and the plug, oil guide pin, vent pipe, or right crankshaft housing. It also allows for better control of the consistency of the press-fitting force, minimizing damage to the surfaces of the plug, oil guide pin, vent pipe, or right crankshaft housing. The support platform and positioning mechanism facilitate the positioning and fixing of the right crankshaft housing. After positioning and fixing, the process holes, oil guide pin mounting holes, and vent pipe mounting holes of the right crankshaft housing requiring press-fitting are aligned with the first, second, and third pressing mechanisms, respectively, allowing for convenient and rapid press-fitting of the plug, oil guide pin, and vent pipe using the press-fitting assembly. The first, second, and third pressing mechanisms can simultaneously press the right crankshaft housing, further improving pressing efficiency. Moreover, since the first, second, and third pressing mechanisms are spaced apart along the circumference of the support platform, the pressing forces from the first, second, and third pressing mechanisms can cancel each other out, thereby reducing the resultant force on the right crankshaft housing and further preventing positional changes in the right crankshaft housing during pressing, thus improving pressing quality.

[0009] According to an embodiment of the present invention, a right crankcase pressing device includes a first pressing mechanism comprising a first driving member and a first pressing head, wherein the first pressing head is detachably mounted on the output end of the first driving member.

[0010] According to an embodiment of the present invention, a right crankcase pressing device further includes a first pressing mechanism, wherein the buffer module is connected between the output end of the first driving member and the body of the first driving member.

[0011] According to an embodiment of the present invention, a right crankcase pressing device includes a buffer module comprising a connecting block, a fixing block, and a plurality of springs. The connecting block is fixedly connected to the output end of a first driving member, the fixing block is fixedly connected to the body of the first driving member, and the plurality of springs are connected to the side of the fixing block near the connecting block and disposed between the connecting block and the fixing block.

[0012] According to an embodiment of the present invention, a right crankcase pressing device includes a buffer module that further includes multiple guide posts. One end of each guide post is fixedly connected to the side of the connecting block near the fixed block, and the other end of each guide post is movably disposed through the fixed block. Multiple springs are correspondingly sleeved on the outside of the multiple guide posts.

[0013] According to an embodiment of the present invention, a right crankcase pressing device includes a first pressing mechanism that further includes a protective plate disposed above the buffer module.

[0014] According to an embodiment of the present invention, a right crankcase pressing device includes a second pressing mechanism comprising a second driving member and a second pressing head, wherein the second pressing head is detachably mounted on the output end of the second driving member.

[0016] According to an embodiment of the present invention, a right crankcase pressing device further includes a machine base, on which both the support platform and the pressing assembly are mounted.

[0017] According to an embodiment of the present invention, a right crankcase pressing device further includes a control box, which is used to control the operation of the positioning mechanism and the pressing assembly.

[0036] The right crankcase of the motorcycle 800 requires press-fitting of a plug, an oil guide pin, and a vent pipe. The plug is usually made of metal and is a solid, truncated cone-shaped structure with one end larger than the other. The oil guide pin is a long cylindrical structure, usually with an oil hole at a specific angle. The vent pipe is a tubular structure, with one end being a conical tube for easy press-fitting and the other end being a pagoda-shaped tube for connecting to a plastic hose.

[0037] Reference Figures 1 to 3This utility model embodiment provides a right crankshaft housing press-fitting device, including a positioning component and a press-fitting component. The positioning component includes a support platform 200 and a positioning mechanism 300. The positioning mechanism 300 is installed above the support platform 200. The support platform 200 is used to support the right crankshaft housing 800, and the positioning mechanism 300 is used to position and fix the right crankshaft housing 800. Specifically, the right crankshaft housing 800 is placed on the support platform 200, and then the positioning mechanism 300 positions the right crankshaft housing 800. The press-fitting component includes a first pressing mechanism 400, a second pressing mechanism 400, and a third pressing mechanism 400. The first pushing mechanism 400, the second pushing mechanism 500, and the third pushing mechanism 600 are arranged on the side of the support platform 200. The first pushing mechanism 400, the second pushing mechanism 500, and the third pushing mechanism 600 are arranged at intervals along the circumference of the support platform 200. Specifically, the first pushing mechanism 400, the second pushing mechanism 500, and the third pushing mechanism 600 can all push towards the support platform 200 to push the plug, oil guide pin, and vent pipe (not shown) into the right crankshaft housing 800.

[0038] Specifically, refer to Figure 1 and Figure 3 The positioning mechanism 300 includes a first positioning post 310, a second positioning post 320, and multiple clamping modules 330. The first positioning post 310 and the second positioning post 320 are both cylindrical and mounted on the top surface of the support platform 200. The first positioning post 310 and the second positioning post 320 can match two larger holes in the right crankshaft housing 800 to achieve positioning and limiting fixation of the right crankshaft housing 800. The multiple clamping modules 330 are mounted on the top surface of the support platform 200 near the edge, and are spaced apart circumferentially along the support platform 200. The multiple clamping modules 330 are used to clamp and fix the right crankshaft housing 800. The clamping module 330 can be a combination of a rotary clamping cylinder, a control solenoid valve, and a clamping block; it can also be a combination of a rotary motor and a clamping block; or it can be other devices or combinations of devices capable of clamping.

[0039] By utilizing the first pressing mechanism 400, the second pressing mechanism 500, and the third pressing mechanism 600, the plug, oil guide pin, and vent pipe can be pressed into the right crankshaft housing 800 respectively, improving the pressing effect. This eliminates the need for workers to use hammering tools for installation, saving manpower and increasing pressing speed. A single pressing operation by the first pressing mechanism 400, the second pressing mechanism 500, and the third pressing mechanism 600 can achieve the pressing of the plug, oil guide pin, and vent pipe, reducing the number of contacts between the pressing device and the plug, oil guide pin, vent pipe, or right crankshaft housing 800. Furthermore, it allows for better control of the consistency of pressing force, reducing damage to the surfaces of the plug, oil guide pin, vent pipe, or right crankshaft housing 800. The support platform 200 and positioning mechanism 300 are used to conveniently position and fix the right crankshaft housing 800. After positioning and fixing, the process holes, oil guide pin mounting holes and vent pipe mounting holes of the right crankshaft housing 800 that need to be press-fitted are aligned with the first pressing mechanism 400, the second pressing mechanism 500 and the third pressing mechanism 600, respectively, so as to facilitate and quickly press-fit the plug, oil guide pin and vent pipe through the press-fitting components. The first pressing mechanism 400, the second pressing mechanism 500, and the third pressing mechanism 600 can simultaneously press the plug, oil guide pin, and vent pipe onto the right crankshaft housing 800, further improving the pressing efficiency. Moreover, since the first pressing mechanism 400, the second pressing mechanism 500, and the third pressing mechanism 600 are spaced apart circumferentially along the support platform 200, the pressing forces from the first pressing mechanism 400, the second pressing mechanism 500, and the third pressing mechanism 600 can cancel each other out, thereby reducing the resultant force on the right crankshaft housing 800 and further preventing the right crankshaft housing 800 from changing position during the pressing process, thus improving the pressing quality.

[0040] According to some embodiments of this application, refer to Figures 1 to 3 The first pressing mechanism 400 includes a first driving member 410 and a first pressing head 420, the first pressing head 420 being detachably mounted on the output end of the first driving member 410. Optionally, the first pressing head 420 can be adapted to a plug, an oil guide pin, or a vent pipe for pressing and installing the plug, oil guide pin, or vent pipe. The detachable structure allows for easy replacement of different first pressing heads 420 according to different applications. Specifically, the first driving member 410 is a double-acting cylinder, a double-acting hydraulic cylinder, or other device capable of forward pressing or backward retraction. The first driving member 410 drives the first pressing head 420 to move towards the right crankshaft housing 800, which is fixedly placed in the positioning assembly, to press the plug, oil guide pin, or vent pipe into the right crankshaft housing 800.

[0041] Furthermore, referring to Figure 2The first pushing mechanism 400 also includes a buffer module 430, which is connected between the output end of the first driving member 410 and the body of the first driving member 410, so that the output end of the first driving member 410 can be buffered when it retracts, thereby extending the service life of the first driving member 410.

[0042] Furthermore, referring to Figure 2 The buffer module 430 includes a connecting block 431, a fixing block 432, and multiple springs 433. The connecting block 431 is fixedly connected to the output end of the first driving member 410, the fixing block 432 is fixedly connected to the body of the first driving member 410, and the multiple springs 433 are connected to the side of the fixing block 432 near the connecting block 431 and are disposed between the connecting block 431 and the fixing block 432. When the output end of the first driving member 410 retracts, it causes the connecting block 431 fixedly connected to the output end of the first driving member 410 to retract as well. At this time, since the fixing block 432 is fixedly connected to the body of the first driving member 410 and the multiple springs 433 are disposed between the connecting block 431 and the fixing block 432, the multiple springs 433 can play a buffering role, preventing the output end of the first driving member 410 from directly causing too much impact on the body of the first driving member 410, thus extending the service life of the first driving member 410.

[0043] Furthermore, referring to Figure 2 The buffer module 430 also includes multiple guide posts 434. One end of each guide post 434 is fixedly connected to the side of the connecting block 431 near the fixing block 432, and the other end of each guide post 434 is movably disposed through the fixing block 432. Multiple springs 433 are correspondingly sleeved on the outside of the guide posts 434. Specifically, the fixing block 432 is provided with multiple through holes, and the other ends of the guide posts 434 are correspondingly inserted into the multiple through holes, which can guide the guide posts 434, thereby guiding the output end of the connecting block 431 and the first driving member 410, improving the consistency of the forward pressing or backward retraction trajectory of the output end of the first driving member 410. The multiple springs 433 are correspondingly sleeved on the outside of the guide posts 434, which can achieve the positioning effect of the multiple springs 433, enabling the multiple springs 433 to better perform the buffering function.

[0044] According to some embodiments of this application, refer to Figure 2 The first pushing mechanism 400 also includes a protective plate 440, which is disposed above the buffer module 430. The protective plate 440 is used to isolate the operating space of the buffer module 430 from the external space, so as to prevent the buffer module 430 from colliding with external devices or workers during operation, thereby improving safety.

[0045] According to some embodiments of this application, refer to Figure 1 and Figure 3 The second pressing mechanism 500 includes a second driving member 510 and a second pressing head 520, the second pressing head 520 being detachably mounted on the output end of the second driving member 510. Optionally, the second pressing head 520 can be adapted to a plug, an oil guide pin, or a vent pipe for pressing and installing the plug, oil guide pin, or vent pipe. The detachable structure allows for easy replacement of different second pressing heads 520 according to different applications. Specifically, the second driving member 510 is a double-acting cylinder, a double-acting hydraulic cylinder, or other device capable of forward pressing or backward retraction. The second driving member 510 drives the second pressing head 520 to move towards the right crankshaft housing 800, which is fixedly placed in the positioning assembly, to press the plug, oil guide pin, or vent pipe into the right crankshaft housing 800.

[0046] According to some embodiments of this application, refer to Figure 1 and Figure 3 The third pressing mechanism 600 includes a third driving member 610 and a third pressing head 620, the third pressing head 620 being detachably mounted on the output end of the third driving member 610. Optionally, the third pressing head 620 can be adapted to a plug, an oil guide pin, or a vent pipe for pressing and installing the plug, oil guide pin, or vent pipe. The detachable structure allows for easy replacement of different third pressing heads 620 according to different applications. Specifically, the third driving member 610 is a double-acting cylinder, a double-acting hydraulic cylinder, or other device capable of forward pressing or backward retraction. The third driving member 610 drives the third pressing head 620 to move towards the right crankshaft housing 800, which is fixedly placed in the positioning assembly, to press the plug, oil guide pin, or vent pipe into the right crankshaft housing 800.

[0047] It should be noted that, referring to Figure 1 and Figure 3 The first pressure head 420, the second pressure head 520 and the third pressure head 620 have different structures. The first pressure head 420, the second pressure head 520 and the third pressure head 620 are respectively matched with the plug, the oil guide pin and the vent pipe to facilitate the matching and pressing of the plug, the oil guide pin and the vent pipe.

[0048] As a preferred embodiment, the first pressure head 420 is matched with the plug and can press the plug into the right crankshaft housing 800; the second pressure head 520 is matched with the oil guide pin and can press the oil guide pin into the right crankshaft housing 800; the third pressure head 620 is matched with the vent pipe and can press the vent pipe into the right crankshaft housing 800.

[0049] As a preferred option, refer to Figure 1 and Figure 3The second driving component 510, the third driving component 610 and the first driving component 410 have the same structure, and all include a buffer module 430 and a protective plate 440.

[0050] According to some embodiments of this application, refer to Figure 1 and Figure 3 It also includes a machine base 100, a support platform 200 and a pressing assembly, all of which are installed on the machine base 100 to improve the stability of the relative position of the support platform 200 and the pressing assembly, thereby improving the stability of the relative position between the right crankshaft housing 800, which is positioned on the support platform 200 and the pressing assembly, and improving the consistency of the pressing effect.

[0051] According to some embodiments of this application, refer to Figure 1 The system also includes a control box 700, which controls the movement of the positioning mechanism 300 and the pressing assembly. Specifically, control devices are installed on the connection channels between the first drive member 410, the second drive member 510, the third drive member 610 and the external power source (such as a high-pressure air source or a hydraulic oil source). For example, when the first drive member 410, the second drive member 510, and the third drive member 610 are all double-acting cylinders, the external power source is a high-pressure air source, and the control device is a solenoid valve. In this case, the control box 700 is electrically connected to these solenoid valves to control the connection or disconnection between the first drive member 410, the second drive member 510, the third drive member 610 and the high-pressure air source. Specifically, the control box 700 is also electrically connected to the clamping module 330 to control the clamping and releasing actions of the clamping module 330. The control box 700 facilitates the control of the movement of the positioning mechanism 300 and the pressing assembly.

[0052] Understandably, referring to Figure 1 and Figure 3 In some other embodiments, the machine tool 100 is also equipped with three pressure relief devices 110. These pressure relief devices 110 are respectively connected between the first drive member 410 and the external power source, the second drive member 510 and the external power source, and the third drive member 610 and the external power source. The pressure relief devices 110 can release the pressure of the first drive member 410, the second drive member 510, or the third drive member 610, so as to quickly relieve the pressure of the first drive member 410, the second drive member 510, or the third drive member 610 on the right crankshaft housing 800 in an emergency. Specifically, the pressure relief device 110 is a push-button type pressure relief valve. When the button switch of the pressure relief valve is manually pressed, the pressure relief valve can be connected to the external environment so as to quickly release the pressure in the first drive member 410, the second drive member 510, or the third drive member 610.

[0053] Working principle: The right crankshaft housing 800 is placed on the support platform 200. At this time, the first positioning pin 310 and the second positioning pin 320 position the right crankshaft housing 800. Then, the clamping module 330 clamps and fixes the right crankshaft housing 800. The smaller diameter end of the plug is inserted into the process hole of the right crankshaft housing 800, the oil guide pin is inserted into the oil guide pin mounting hole of the right crankshaft housing 800, and the conical end of the vent pipe is inserted into the vent pipe mounting hole of the right crankshaft housing 800. The first drive component 410, the second drive component 510, and the third drive component 610 are operated simultaneously, as shown in the figure. Figure 3 The first drive unit 410, the second drive unit 510 and the third drive unit 610 respectively drive the first pressure head 420, the second pressure head 520 and the third pressure head 620 to move simultaneously toward the support platform 200, so as to push the plug, oil guide pin and vent pipe to press into the right crankshaft housing 800; operate the first drive unit 410, the second drive unit 510 and the third drive unit 610 and the clamping module 330 to retract, and complete one right crankshaft housing press-fit process.
