Description

Technical Field

[0001] The utility model relates to the technical field of nut production equipment, and in particular to a large nut pre-setting device. Background Art

[0002] A nut is a screw cap. Through the internal thread, nuts and bolts of the same specification can be screwed together to play a fastening role. It is a component that must be used in all production and manufacturing machinery. According to different materials, it can be divided into several major types such as carbon steel, stainless steel, and non-ferrous metals. Nuts have the characteristics of being easy to install, not requiring washers, being easy to disassemble, and being reusable.

[0003] In the production process of nuts, after the punching machine punches and forms the blank, after the formed nuts are cooled, the internal threads of the nuts need to be processed. However, in the production process, the formed and cooled nuts are stored in large containers in piles. When the internal threads need to be processed, workers need to manually place each large nut in the processing positioning groove, and manually pick up the tap and place it in the inner circle of the nut, and then drive the clamped tap to rotate through the motor to complete the processing of the internal threads.

[0004] Although the above method can complete the processing of the internal threads of nuts, first, the large nuts themselves are heavy, and a large amount of physical strength is consumed when the operators pick up and place them one by one. Long-term work consumption is likely to cause fatigue of the operators, which in turn affects the processing speed and efficiency. Second, when the motor drives the tap to rotate after the nut is placed in the positioning groove, the operator is easily injured by the tap, and the production safety cannot be guaranteed. Therefore, the utility model provides a large nut pre-setting device. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the above traditional technologies, and provide a large nut pre-setting device, which can realize the internal thread processing process of large nuts without manual intervention, cooperate with other driving devices, ensure the safety of workers, and be free from the influence of human factors, and can ensure the processing efficiency of the internal thread processing procedure.

[0006] The purpose of the utility model is achieved by the following technical measures:

[0007] A large nut presetting device includes an upper placing plate and a lower tapping plate. The lower tapping plate is detachably connected to the bottom of the upper placing plate. Four positioning special-shaped grooves are symmetrically arranged at the center of the side of the upper placing plate facing away from the lower tapping plate. A registering screw cone is arranged in each positioning special-shaped groove. The registering screw cone includes a frustum-shaped outer shell, a sleeve screw cone head, and a telescopic spring. The telescopic spring is coaxially fixed at the bottom of the frustum-shaped outer shell and is arranged in the positioning special-shaped groove. A clamping block is fixedly connected to the middle part inside the telescopic spring. The sleeve screw cone head is fixedly connected to the clamping block. A presetting groove adapted to the large nut is formed on the side of the frustum-shaped outer shell facing away from the telescopic spring. The sleeve screw cone head penetrates through the frustum-shaped outer shell and is movably inserted into the presetting groove. A plurality of placing holes are formed through the lower tapping plate. A tapping tip cone for the large nut to be sleeved thereon is arranged in each placing hole. The tapping tip cone can be movably inserted into the presetting groove.

[0008] For further specific optimization, two rotating bearings are symmetrically sleeved on the tapping tip cone. The outer rings of the two rotating bearings are clamped in the placing holes, and the placing holes are adapted to the tapping tip cone and the rotating bearings.

[0009] For further specific optimization, a matching sleeve for adapting to other driving devices is fixedly connected to the end of the tapping tip cone. The matching sleeve is closely attached to the side of any one of the rotating bearings facing away from the other rotating bearing.

[0010] For further specific optimization, a limiting auxiliary cylinder is connected to the bottom of the frustum-shaped outer shell. The sleeve screw cone head is slidably arranged in the limiting auxiliary cylinder, and the limiting auxiliary cylinder is inserted into the frustum-shaped outer shell.

[0029] Embodiment:

[0030] A large nut presetting device comprises an upper placing plate 1 and a lower tapping plate 2, wherein the lower tapping plate 2 is detachably connected to the bottom of the upper placing plate 1, and the upper placing plate 1 is centrally symmetrically provided with four positioning special-shaped grooves 3 on one side away from the lower tapping plate 2, wherein each positioning special-shaped groove 3 is provided with a registration screw cone 4, and the registration screw cone 4 comprises a truncated cone shell 5, a registration screw cone head 6 and a telescopic spring 7, wherein the telescopic spring 7 is coaxially fixed to the bottom of the truncated cone shell 5 and is provided in the positioning special-shaped groove 3, and the telescopic spring A clamping block 8 is fixedly connected to the middle part of 7, and a screw cone head 6 is fixedly connected to the clamping block 8. A preset groove 9 adapted to a large nut is provided on the side of the truncated cone housing 5 away from the telescopic spring 7. The screw cone head 6 penetrates the truncated cone housing 5 and is movably inserted in the preset groove 9. A plurality of placement holes 10 are penetrated and opened on the lower tapping plate 2. Each placement hole 10 is provided with a tapping cone 11 for a large nut to be sleeved thereon, and the tapping cone 11 can be movably inserted in the preset groove 9.

[0031] Through the above technical solution, when it is necessary to perform internal thread processing on the large nuts formed by stamping, the upper placing plate 1 is first clamped on the clamping device, and then the lower tapping plate 2 is removed from the upper placing plate 1, and then the lower tapping plate 2 is connected to other driving devices, so that the lower tapping plate 2 is above the upper placing plate 1 and parallel to the upper placing plate 1. Since the telescopic spring 7 and the clamping block 8 of the alignment screw cone 4 are arranged in the positioning special-shaped groove 3, when the telescopic spring 7 is at its original length, the screw cone head 6 extends out of the positioning special-shaped groove 3, and then the large nuts placed in a pile at random can be inserted into the alignment screw cone by moving and shaking the upper placing plate 1. The cone head 6, and the screw cone head 6 falls into the preset groove 9 for placing the nut, and then the upper placement plate 1 is driven to fit with the lower tapping plate 2, so that the truncated cone shell 5 is inserted into the corresponding placement hole 10. At this time, the screw cone head 6 is resisted by the tapping cone 11, and the screw cone head 6 drives the clamping block 8 to squeeze the telescopic spring 7, so that the screw cone head 6 is retracted into the positioning special-shaped groove 3. At the same time, the truncated cone shell 5 pushes the large nut that falls into the preset groove 9 to be sleeved on the tapping cone 11, and then the driving device is used to drive the tapping cone 11 to rotate to complete the internal thread processing of the stamped nut.

[0032] Then, it is only necessary to flip the upper placement plate 1 and drive it to shake, so that the nuts with processed internal threads can be shaken into and out of the storage tool, completing the automated operation without manual operation. It can cooperate with other driving equipment to realize the internal thread processing process of large nuts, which can ensure the safety of the staff and is not affected by human factors, thereby ensuring the processing efficiency of the internal thread processing process.

[0033] The lower tapping plate 2 is equipped with a spraying component for cooling down to ensure the feasibility of pre-setting tapping.

[0034] Two rotary bearings 12 are symmetrically sleeved on the tapping taper 11. The outer rings of the two rotary bearings 12 are clamped in the placement hole 10. The placement hole 10 is adapted to the tapping taper 11 and the rotary bearings 12. After separating the upper placement plate 1 from the lower placement plate, the lower placement plate is fixed so that the tapping taper 11 is connected to the driving end of other driving devices. The driving device drives the tapping taper 11 to rotate in the placement hole 10, and then taps the large nut sleeved on it to process internal threads.

[0035] A mating sleeve 13 for adapting to other driving devices is fixedly connected to the end of the tapping taper 11. The mating sleeve 13 is attached to one side of any one rotary bearing 12 facing away from the other rotary bearing 12. By connecting with other driving devices using the mating sleeve 13, the connection stability of the tapping taper 11 can be improved, ensuring the stable rotation of the tapping taper 11, and thus ensuring the machining accuracy.

[0036] A limiting auxiliary cylinder 14 is connected to the bottom of the frustum-shaped housing 5. The sleeve tapping cone 6 is slidably arranged in the limiting auxiliary cylinder 14, and the limiting auxiliary cylinder 14 is inserted into the frustum-shaped housing 5. When the sleeve tapping cone 6 is squeezed by the tapping taper 11, the limiting auxiliary cylinder 14 can ensure that the sleeve tapping cone 6 can be limited within a longer stroke when retracting into the positioning special-shaped groove 3, ensuring the stability of the sleeve tapping cone 6, and at the same time, it is more convenient during installation.

[0037] A plurality of positioning magnetic posts 15 are penetrated through the lower tapping plate 2. A plurality of positioning iron blocks 16 are fixedly connected to the bottom of the upper placement plate 1. The plurality of positioning iron blocks 16 are arranged in one-to-one correspondence with the positioning magnetic posts 15. By the cooperation of the positioning magnetic posts 15 and the positioning iron blocks 16, when in use, the two can be separated for internal thread processing. When not in use, the upper placement plate 1 and the lower tapping plate 2 can be attracted together, facilitating storage.

[0038] A sunken groove 17 matching the special-shaped positioning groove is formed on the upper placement plate 1. An extended edge 18 is fixedly connected to the frustum-shaped housing 5. The thickness of the extended edge 18 is the same as the depth of the sunken groove 17. By fixing the extended edge 18 in the sunken groove 17, the stability of the sleeve tapping cone 6 when sleeving the nut can be improved, and when the upper placement plate 1 is flipped to separate the processed nut, it can prevent the sleeve alignment cone 4 from falling out of the positioning special-shaped groove 3, ensuring the safety of processing.

[0039] Limiting clamping grooves 19 are formed on both sides of the upper placement plate 1. Edge grooves 20 for fixing the upper placement plate 1 are also symmetrically arranged on the upper placement plate 1. The upper placement plate 1 is clamped by other driving devices through the limiting clamping grooves 19 on both sides, and the edge grooves 20 can also contact other devices to fix the upper placement plate 1, thereby improving the stability of the upper placement plate 1, ensuring the stability of the nut when the tapping taper 11 is performing internal thread processing, and improving the machining accuracy.
