Description

Technical Field

[0001] The utility model relates to the technical field of valve lock clip assembly, in particular to valve lock clip assembly equipment. Background Art

[0002] The valve lock clip is a device used to fix the valve stem, usually composed of a valve spring and a valve lock clip. The valve lock clip can prevent the valve from closing accidentally during engine operation, ensuring that the valve opens and closes at the correct time, thereby ensuring the normal operation of the engine;

[0003] When using existing valve lock clamp assembly equipment, a press machine is usually used to press and assemble the valve spring and the valve stem. During the process, foreign matter and impurities in the environment may splash onto the press rod of the press, which may cause the press rod to be unable to retract smoothly and affect the assembly accuracy. In addition, due to different valve lock clamp models, the installation heights are also different, and it is difficult to control the extension and retraction of the push rod. The valve push rod may be slightly offset during assembly, making it difficult to install in the exact position. At the same time, directly pulling the assembly pressure head for a long time to replace it can easily cause the press rod to tilt, which may interfere with the subsequent assembly stability.

[0020] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0021] like Figure 1-3 As shown, a valve lock clip assembly device includes a support platform 1, an assembly chassis body 2 is arranged on the top of the support platform 1, and a plurality of valve lock clip bodies 3 are arranged inside the assembly chassis body 2, and a press-fitting component 4 is arranged on the top of the support platform 1, and the press-fitting component 4 includes a mounting plate 5;

[0022] The mounting plate 5 is fixedly connected and installed on one side of the top of the support platform 1. A driving cylinder 6 is installed on the top of the mounting plate 5. A pressing rod 7 is connected to the bottom end of the driving cylinder 6. The end of the pressing rod 7 away from the driving cylinder 6 passes through the mounting plate 5 and is fixedly connected with a connecting head 8. The bottom end of the connecting head 8 is threadedly connected with a pressing head 9 through a threaded extension head. The top of the connecting head 8 is fixedly connected with a connecting block 10. Sliding rods 12 are fixedly connected to the top of the support platform 1 and close to the front and rear ends of the pressing rod 7. Limiting blocks 11 are slidably installed on the outer rings of the two sliding rods 12. The limiting blocks 11 are connected to the connecting blocks 10 through fixing bolts.

[0023] In this embodiment, the top end of the slide rod 12 is fixedly connected to the mounting plate 5, and the outer ring of the slide rod 12 is provided with external threads near the upper and lower ends. The lower position of the outer ring of the slide rod 12 is threadedly connected to a fixing block 2 14 through an external thread, and the upper position of the outer ring of the slide rod 12 is threadedly connected to a fixing block 13 through an external thread. By twisting the fixing block 2 14 or the fixing block 1 13, the position of the fixing block 2 14 or the fixing block 13 can be raised or lowered, thereby adjusting the blocking height of the limit block 11 to prevent the press head 9 from moving to a dangerous position.

[0024] In this embodiment, the fixing block 1 13 and the fixing block 2 14 are both slidably connected to the portion of the slide rod 12 where no external thread is provided, and the sizes of the fixing block 13 and the fixing block 2 14 match each other. By adjusting the fixing block 13 and the fixing block 2 14 to the same external thread and continuously twisting them so that they are against the upper and lower ends of the limit block 11, the press-fitting rod 7 is secondary fixed, thereby reducing the probability of bending the press-fitting rod 7.

[0025] In this embodiment, the mounting plate 5 is set in an inverted "L" shape, and a cleaning block 15 is set at the upper position of the outer ring of the press-fitting rod 7, and the cleaning block 15 is fixedly connected to the side of the mounting plate 5 close to the press-fitting rod 7. Through the cleaning block 15, when the press-fitting rod 7 is extended or retracted, the outer ring can be aligned for cleaning to prevent possible adhered debris or impurities from following the press-fitting rod 7 into the interior of the driving cylinder 6.

[0026] In this embodiment, the press fitting rod 7 is detachably connected to the press fitting head 9 via the connecting head 8, and the size of the press fitting head 9 matches the valve lock clamp body 3, so that different press fitting heads 9 can be replaced according to the specifications of the valve lock clamp body 3.

[0027] It should be noted that the utility model is a valve lock clamp assembly device. When in use, first, the valve lock clamp body 3 to be assembled can be pre-fixed to a suitable position of the assembly chassis body 2 according to the existing steps, and after being fixed, the valve lock clamp body 3 is moved to the bottom of the press-fitting head 9. After accurate alignment, the press-fitting head 9 is fixed to the end of the press-fitting rod 7 through various components, so that the driving cylinder 6 can be started to extend the press-fitting rod 7 downward, driving the press-fitting head 9 to press-fit the valve lock clamp body 3.

[0028] After the press-fitting head 9 has completed press-fitting one of the valve lock clip bodies 3, the press-fitting rod 7 of the driving cylinder 6 can be retracted by control. During retraction, since the cleaning block 15 is arranged at the upper position of the outer ring of the press-fitting rod 7, the cleaning block 15 cleans and scrapes the outer ring of the press-fitting rod 7, thereby cleaning the debris or impurities that may be adhered to the press-fitting rod 7 during the press-fitting process, so as to prevent them from following the press-fitting rod 7 into the interior of the driving cylinder 6, thereby preventing the sliding stability from being affected;

[0029] When the press-fitting rod 7 moves, the limit block 11 is connected to the press-fitting rod 7 through the connector 8, and the limit block 11 is installed on the outer rings of the two slide bars 12, so that the limit block 11 can be driven to move on the slide bars 12 by the extension and contraction of the press-fitting rod 7, which is convenient for increasing the stability during sliding, reducing the probability of the press-fitting rod 7 deflecting, and improving the press-fitting stability;

[0030] At the same time, the slide rod 12 is threadedly connected with a fixing block 2 14 and a fixing block 1 13. The limit block 11 contacts the fixing block 2 14 or the fixing block 13, which can limit the moving distance of the press-fitting head 9. Therefore, according to the actual situation of the valve lock clamp body 3 to be press-fitted, the fixing block 2 14 or the fixing block 13 can be screwed to raise or lower its position, thereby adjusting the blocking height of the limit block 11;

[0031] It can prevent the press fitting rod 7 from driving the press fitting head 9 to move to a dangerous position due to different specifications of the valve lock clamp body 3, thereby preventing the press fitting head 9 from moving to a dangerous position and crushing the valve lock clamp body 3. At the same time, when replacing a different press fitting head 9 according to the specifications of the valve lock clamp body 3, the limit block 11 can be moved to the external thread on the slide rod 12 by control, and the driving cylinder 6 can be closed for self-locking;

[0032] Because the fixing block 13 is slidably connected to the fixing block 2 14 and the sliding rod 12, the fixing block 13 and the fixing block 2 14 can be adjusted to the same external thread and continuously twisted to make them abut against the upper and lower ends of the limit block 11, so as to perform secondary fixation on the press-fitting rod 7, thereby preventing the press-fitting rod 7 from rocking back and forth when the press-fitting head 9 is pulled and disassembled, thereby reducing the probability of bending the press-fitting rod 7, thereby reducing the frequency of maintenance and replacement, and effectively extending the working time of the press-fitting rod 7, which is convenient for improving assembly efficiency.

[0033] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
