Description

Technical Field

[0001] The invention mainly relates to the technical field of nut processing, and in particular to an automatic nut trimming machine. Background Art

[0002] In the traditional nut processing process, especially the trimming of flange nuts, many of them are done manually. Workers need to pick out nuts one by one from a pile, place them on the processing equipment for trimming, and then remove the nuts after processing. This method is inefficient, manual operation is slow, and as the worker's fatigue increases, the processing speed and quality will be affected. For example, in a small machining plant, workers manually trim flange nuts and may only process dozens of nuts per hour, which is far from meeting the needs of large-scale production.

[0003] The accuracy of manual operation is also difficult to guarantee. During the trimming process, due to human factors, it is difficult to ensure that the cutting knife can accurately cut the edge of the nut every time, which is prone to quality problems such as uneven trimming and rough edges. Moreover, during the grinding process, manual grinding is also difficult to ensure the consistency of grinding, resulting in uneven product quality.

[0004] With the development of the manufacturing industry, the requirements for the processing quality and efficiency of nuts and other parts are getting higher and higher. Enterprises need a device that can efficiently and accurately perform nut trimming. Automated nut trimming machines came into being, which can automatically complete a series of processes such as nut feeding, loading, trimming and unloading, greatly improving production efficiency.

[0005] Although some existing automatic nut trimming machines have achieved automation to a certain extent, they still have deficiencies in terms of feeding continuity, trimming size adjustment flexibility, and overall versatility of the equipment. For example, some trimming machines only have one feeding device. When there is a short interruption in feeding, the equipment needs to stop and wait, which affects production efficiency; some trimming machines have fixed spacing between trimming tools and can only process nuts of one specification. For the processing of nuts of different specifications, different tools or the entire trimming module need to be replaced, which increases production costs and equipment adjustment time.

[0028] The clamping mechanism 10 comprises a pneumatic finger 101 , and clamping blocks 102 are fixedly mounted on two output ends of the pneumatic finger 101 .

[0029] The lifting mechanism 6 includes a support column 61 fixed on the frame 1, a mounting block 62 is provided at the top of the support column 61, a hydraulic cylinder 63 is fixedly installed on the mounting block 62, a lifting plate 64 is provided on the output end of the hydraulic cylinder 63, a linear bearing 65 is provided on the lifting plate 64, and the linear bearing 65 is slidably installed on the support column 61 up and down.

[0030] The trimming mechanism 8 includes an adjusting mechanism, which is used to adjust the distance between the two output ends. A motor mounting seat 84 is fixedly installed on each output end of the adjusting mechanism, and a motor three 85 is fixedly installed on the motor mounting seat 84. A mounting plate 86 is fixed on the output end of the motor three 85. A cutting knife 87 is fixedly installed on the outer side of the mounting plate 86, and a grinding block 88 is fixedly installed on the side thereof.

[0031] The adjustment mechanism includes a rotatably mounted double-headed screw 81, one end of which is connected to a motor 82, and two threaded blocks 83 are threadedly mounted on the double-headed screw 81. When the double-headed screw 81 rotates, the two threaded blocks 83 are driven relatively close to or relatively far away from each other, and the threaded blocks 83 are used to install a motor mounting seat 84.

[0032] Working principle: Feeding mechanism 1 2 and feeding mechanism 2 3 work separately. Taking feeding mechanism 1 2 as an example, the vibration plate 21 is a common automatic feeding device, which arranges the flange nuts 9 in order according to a specific track in the plate through the internal vibration device. The vibration of the vibration plate 21 arranges the flange nuts 9 in order and transports them to the receiving table 22, and the cylinder 1 23 pushes the push plate 24, and the push groove 25 on the push plate 24 pushes a flange nut 9 to the material placement table 26. Feeding mechanism 2 3 performs the feeding operation in the same way.

[0033] The distance between the clamping mechanisms 10 on the two cylinders 3 59, the distance between the feeding mechanism 1 2 and the processing table 4, and the distance between the feeding mechanism 2 3 and the processing table 4 are all equal. When the cylinder 3 59 and the clamping mechanism 10 on the left side are located above the flange nut 9 on the material placement table 26 in the feeding mechanism 1 2, the cylinder 3 59 and the clamping mechanism 10 on the right side are located above the processing table 4. When the cylinder 3 59 and the clamping mechanism 10 on the right side are located above the flange nut 9 on the material placement table 26 in the feeding mechanism 2 3, the cylinder 3 59 and the clamping mechanism 10 on the left side are located above the processing table 4.

[0034] In the initial state, it is assumed that the cylinder three 59 and the clamping mechanism 10 on the left are located above the flange nut 9 on the placing table 26 in the feeding mechanism 1 2 , and the cylinder three 59 and the clamping mechanism 10 on the right are located above the processing table 4 .

[0035] First, the left cylinder 3 59 located above the feeding mechanism 1 2 adjusts the lowering height of the clamping mechanism 10, and the pneumatic finger 101 drives the clamping block 102 to clamp the flange nut 9. Then the left cylinder 3 59 drives the clamping mechanism 10 to rise back to the initial height. Next, the piston rod of the cylinder 2 55 retracts, driving the longitudinal block 57 to move forward. The cylinder 2 55 and the longitudinal block 57 are set to avoid the support column 61. The slider assembly 2 58 at the lower end of the longitudinal block 57 is installed on the transverse block 54 to play a guiding role, ensuring that the longitudinal block 57 can move forward and backward smoothly.

[0036] The motor 1 52 drives the synchronous belt assembly 53 to drive the lateral block 54 to move rightward, so that the right cylinder 3 59 and the clamping mechanism 10 move from above the processing table 4 to above the flange nut 9 on the material placement table 26 in the feeding mechanism 2 3, and at the same time, the left cylinder 3 59 and the clamping mechanism 10 carry the flange nut 9 to move above the processing table 4, and the piston rod of the cylinder 2 55 extends to drive the longitudinal block 57 to move backward, so that the clamping center of the clamping mechanism 10 is located directly above the center of the flange nut 9. Afterwards, the right cylinder 3 59 located above the feeding mechanism 2 3 adjusts the height of the clamping mechanism 10 to descend, the pneumatic finger 101 drives the clamping block 102 to clamp the flange nut 9, and the right cylinder 3 59 drives the clamping mechanism 10 to rise back to the initial height. At this time, the left cylinder 3 59 adjusts the height of the clamping mechanism 10 to descend, places the flange nut 9 on the processing table 4, and then rises back to the initial height. A clamp is provided on the processing table 4 to fix the flange nut 9.

[0037] Then the motor 1 52 drives the synchronous belt assembly 53 again to drive the traverse block 54 to move to the left, and the cylinder 3 59 and the clamping mechanism 10 on the right carry the flange nut 9 from above the feeding mechanism 2 3 to above the processing table 4, and the cylinder 3 59 and the clamping mechanism 10 on the left move from the processing table 4 to the upper feeding mechanism 1 2. Repeating the above steps, the feeding mechanism 5 can alternately grab the flange nut 9 from the feeding mechanism 1 2 and the feeding mechanism 2 3 and place them on the processing table 4, realizing a continuous feeding process, improving the feeding efficiency and ensuring the continuity of production.

[0038] The hydraulic cylinder 63 on the mounting block 62 at the top of the support column 61 fixed on the frame 1 extends its piston after receiving the processing signal. The extension of the piston drives the lifting plate 64 to descend. The linear bearing 65 installed on the lifting plate 64 slides up and down along the support column 61, playing a role in guiding and stabilizing the lifting. The motor 85 installed on the motor mounting seat 84 starts to rotate after being powered on, and its output shaft drives the mounting plate 86 to rotate. The cutting knife 87 on the outside of the mounting plate 86 trims the flange nut 9 as the mounting plate 86 rotates.

[0039] Before trimming, the motor 2 82 drives the double-headed screw 81 to rotate according to the size of the flange nut 9. Due to the effect of the threads, the two threaded blocks 83 on the double-headed screw 81 are relatively close to or relatively far away from each other when the double-headed screw 81 rotates. The threaded blocks 83 drive the motor mounting seat 84 to move, thereby adjusting the distance between the two motors 3 85, that is, adjusting the distance between the two cutting knives 87, to adapt to the trimming of flange nuts 9 of different specifications.

[0040] The grinding block 88 installed on the side of the mounting plate 86 grinds the edge of the nut after the cutting knife 87 trims the edge. The adjustment mechanism can also adjust the position of the mounting plate 86. By adjusting the spacing of the grinding blocks 88 through the double-headed screw 81, the grinding blocks 88 can be accurately fitted to the edge of the nut, ensuring that nuts of various specifications can be effectively polished. Accurate spacing adjustment can ensure that the two grinding blocks 88 maintain uniform contact pressure and a suitable contact angle with the edge of the nut during the grinding process. In this way, the edge of the nut after grinding can be smoother and flatter, reducing grinding defects, and improving the grinding accuracy and quality of the product.

[0041] The rotating cylinder 71 rotates to the top of the processing table 4, and the cylinder 4 72 drives the connecting plate 73 to descend, and the clamping mechanism 10 on the connecting plate 73 clamps the processed flange nut 9. Then the cylinder 4 72 drives the connecting plate 73 to rise, and the rotating cylinder 71 rotates to the top of the unloading chute 74, and the cylinder 4 72 drives the connecting plate 73 to descend again, and the clamping mechanism 10 loosens the flange nut 9, and the flange nut 9 slides along the unloading chute 74 into the collection box 75.

[0042] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
