Description

Technical Field

[0001] This utility model relates to the field of nut assembly technology, and in particular to a high-precision assembly device for hexagonal flange nuts. Background Technology

[0002] With the rapid development of modern industry, hexagonal flange nuts, as key fasteners, are widely used in automobile manufacturing, construction machinery, aerospace, rail transportation, and other fields. Their assembly quality directly affects the stability and safety of equipment operation. In scenarios such as high-pressure pipeline connections and heavy machinery structural component fixing, hexagonal flange nuts, through the integrated anti-slip teeth and sealing gasket design, can effectively resist vibration and prevent loosening. However, their high-precision assembly requirements pose a severe challenge to traditional processes. Traditional assembly methods rely on manual operation, which is not only inefficient but also susceptible to subjective factors, making it difficult to meet key requirements such as torque control accuracy and perpendicularity deviation. Especially under complex working conditions (such as oily or corrosive environments), errors in human judgment are more likely to lead to assembly failure.

[0003] In current technology, the assembly of nuts is mostly done using torque wrenches, but this requires workers to put the nuts in their pockets and place them on top of the bolts before assembly. If multiple nuts need to be assembled, the work efficiency is low and it takes a long time. Therefore, we propose a high-precision assembly device for hexagonal flange nuts. Utility Model Content

[0007] The high-precision nut cutting and assembly assembly includes a rotating cylinder, a replaceable nut assembly bracket, and a fixing bolt. The rotating cylinder is rotatably mounted on the bottom of the nut placement bracket, the replaceable nut assembly bracket is located inside the rotating cylinder, and the fixing bolt is threaded onto the inside of the rotating cylinder.

The motor is fixedly installed at the bottom of the nut placement bracket, the drive shaft is fixedly installed at the output end of the motor, and the transmission gear is fixedly installed on the outside of the drive shaft and the rotating cylinder, with adjacent transmission gears meshing.

[0010] As a further improvement to the above solution, the continuous nut feeding limiting assembly includes a nut storage slot, a nut clamping slot, a second mounting bracket, and a sliding limiting bracket. The nut storage slot is located at the top of the nut placement bracket, the nut clamping slot is located on the right side of the nut placement bracket, the second mounting bracket is fixedly installed on the outside of the nut placement bracket, and the sliding limiting bracket is slidably installed on the inside of the second mounting bracket.

[0011] As a further improvement to the above solution, a locking bolt is installed on the inner thread of the second mounting bracket, and an anti-slip pad is rotatably installed on one end of the locking bolt and the fixing bolt. The anti-slip pad abuts against the sliding limit bracket and the replaceable nut assembly bracket.

[0012] As a further improvement to the above solution, the top of the second mounting bracket is provided with a sliding groove, and the sliding limit bracket is slidably installed on the inner side of the sliding groove. Both the sliding limit bracket and the sliding groove are U-shaped.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] (1) The present invention provides a high-precision assembly device for hexagonal flange nuts. By setting a high-precision nut cutting and assembly component, when assembling multiple nuts, multiple nuts can be stacked and placed inside the nut storage slot on the inner side of the nut placement frame. The position of the sliding limit frame is adjusted according to the height of the assembled nuts, so that the sliding limit frame slides inside the second mounting frame. After the sliding limit frame blocks the nut clamping slot, it can ensure that when the clamping caliper clamps the nut, only one nut can be pulled out, so that the device can work continuously.

[0017] (2) The present invention provides a high-precision assembly device for hexagonal flange nuts. Through the setting of a nut continuous feeding limit component, the clamping caliper is controlled to clamp the nut, and the electric telescopic rod drives the clamping caliper to move to the initial position.

A torque sensor is set above the motor. When the torque reaches a certain value when the replaceable nut assembly frame drives the nut assembly, it can stop in time, so that the device has a better assembly effect.

[0028] The high-precision nut cutting and assembly assembly 1 includes a rotating cylinder 11, a replaceable nut assembly bracket 12, and a fixing bolt 13. The rotating cylinder 11 is rotatably mounted on the bottom of the nut placement bracket 8, the replaceable nut assembly bracket 12 is located inside the rotating cylinder 11, and the fixing bolt 13 is threadedly mounted on the inside of the rotating cylinder 11.

[0029] In a further preferred embodiment of the present invention, a grip handle 4 is fixedly installed on the top of the first mounting bracket 3, and a nut continuous feeding limit component 2 is provided above the nut placement bracket 8.

[0030] In a further preferred embodiment of the present invention, the high-precision nut unloading assembly 1 further includes a motor 14, a drive shaft 15, and a transmission gear 16. The motor 14 is fixedly installed at the bottom of the nut placement bracket 8, the drive shaft 15 is fixedly installed at the output end of the motor 14, and the transmission gear 16 is fixedly installed on the outside of the drive shaft 15 and the rotating cylinder 11, with adjacent transmission gears 16 meshing with each other.

[0031] In a further preferred embodiment of the present invention, the continuous nut feeding limiting assembly 2 includes a nut storage groove 21, a nut clamping groove 22, a second mounting frame 23, and a sliding limiting frame 24. The nut storage groove 21 is opened on the top of the nut placement frame 8, the nut clamping groove 22 is opened on the right side of the nut placement frame 8, the second mounting frame 23 is fixedly installed on the outside of the nut placement frame 8, and the sliding limiting frame 24 is slidably installed on the inside of the second mounting frame 23.

[0032] In a further preferred embodiment of the present invention, a locking bolt 25 is threaded on the inner side of the second mounting bracket 23, and an anti-slip pad is rotatably mounted on one end of the locking bolt 25 and the fixing bolt 13. The anti-slip pad abuts against the sliding limit bracket 24 and the replaceable nut assembly bracket 12.

[0033] In a further preferred embodiment of this utility model, a sliding groove 26 is provided on the top of the second mounting bracket 23, and a sliding limit bracket 24 is slidably installed inside the sliding groove 26. Both the sliding limit bracket 24 and the sliding groove 26 are U-shaped. When assembling multiple nuts, multiple nuts can be stacked and placed inside the nut storage groove 21 inside the nut placement bracket 8. The position of the sliding limit bracket 24 is adjusted according to the height of the assembled nuts, so that the sliding limit bracket 24 slides inside the second mounting bracket 23. After the sliding limit bracket 24 blocks the nut clamping groove 22, it can ensure that when the clamping caliper 7 clamps the nut, only one nut can slide out.

[0034] In a further preferred embodiment of this utility model, a high-definition industrial camera is fixedly installed on the top inner wall of the first mounting frame 3, and a torque sensor is fixedly installed above the rotating cylinder 11.

The nut assembly groove is larger than the size of the nut, so that the nut can fall into the inner side of the replaceable nut assembly rack 12 after it is lowered. This device needs to be placed above the bolt in advance so that the nut will not fall off during the assembly process.

[0036] Specifically, when assembling multiple nuts, the nuts can be stacked inside the nut storage slot 21 on the inner side of the nut placement rack 8. The position of the sliding limit rack 24 is adjusted according to the height of the assembled nuts, allowing the sliding limit rack 24 to slide inside the second mounting rack 23. After the sliding limit rack 24 blocks the nut clamping slot 22, it ensures that when the clamping caliper 7 clamps the nut, only one nut can slide out, thus enabling the device to work continuously. The replaceable nut assembly rack 12 is inserted into the inner side of the rotating cylinder 11, and the fixing bolt 13 is used to abut against the replaceable nut assembly rack 12, while the locking bolt 25 abuts against the sliding limit rack 24, ensuring that the sliding limit rack 24 and the replaceable nut assembly rack 12 will not become loose during the operation of the device.

[0037] The electric telescopic rod 5 drives the fixed box 6 and clamping caliper 7 to move. After the clamping caliper 7 slides into the inner side of the nut clamping slot 22, it can be controlled to clamp the nut, allowing the electric telescopic rod 5 to drive the clamping caliper 7 to move to the initial position. A high-definition camera is installed on the top inner wall of the first mounting frame 3. The camera can capture the position of the clamped nut. The motor 14 drives the drive shaft 15 and the transmission gear 16 to rotate. After the transmission gear 16 meshes, it can drive the rotating cylinder 11 and the replaceable nut assembly frame 12 to rotate. After the assembly slot above the replaceable nut assembly frame 12 is adapted to the nut, the clamping caliper 7 can be controlled to release the clamp, allowing the nut to descend to the inner side of the replaceable nut assembly frame 12. A torque sensor is installed above the rotating cylinder 11. When the torque reaches a certain value when the replaceable nut assembly frame 12 drives the nut assembly, it can stop in time, making the device have a better assembly effect.
