Description

Technical Field

[0001] This application relates to the field of nut manufacturing, and in particular to a positioning device for a nut tapping machine. Background Technology

[0002] Nut machining requires a nut tapping machine, a specialized machining tool used to create internal threads in the holes of nuts and other parts. The positioning device is a key component ensuring that the nut is precisely aligned and securely clamped during machining.

[0003] Most existing nut tapping machine positioning devices consist of a machine body, drive mechanism, positioning seat, clamping mechanism, and limiting mechanism. The drive mechanism is installed inside the machine body and drives the positioning seat to rotate on the upper side of the machine body. The positioning seat is used to load nuts and limit their position. The clamping mechanism is installed on one side of the positioning seat and is used to fix the nut on the upper side of the positioning seat. The limiting mechanism is installed at the upper end of the machine body to prevent the nut from detaching from the positioning seat. In use, the feeding mechanism of the tapping machine feeds the nut onto the positioning seat. The limiting mechanism then restricts the nut onto the positioning seat. The clamping mechanism then clamps and fixes the nut to be processed. The tapping drill bit of the tapping machine is then used to tap the nut. After processing, the nut is removed, completing the nut tapping process.

[0004] In the existing technology, when the type or size of the nut changes, the positioning seat needs to be replaced accordingly. However, the existing equipment is not convenient for replacing the positioning seat, and the operation is time-consuming and labor-intensive. This not only increases the downtime of the equipment, but also affects the tapping efficiency of the nut. Utility Model Content

[0005] To facilitate the installation or replacement of the positioning seat and improve the tapping efficiency of nuts, this application provides a positioning device for a nut tapping machine.

[0006] The positioning device for a nut tapping machine provided in this application adopts the following technical solution: A nut tapping machine positioning device includes a machine body, a positioning mechanism mounted on the upper side of the machine body, and a clamping mechanism mounted on the upper side of the machine body. One side of the positioning mechanism is provided with a guide rod fixedly connected to the machine body. The positioning mechanism includes a rotating disk and a fixed ring. The rotating disk is driven by a motor inside the machine body. The fixed ring is mounted on the outer side of the rotating disk. Both ends of the rotating disk are equipped with locking elements for locking the fixed ring. One end of the clamping mechanism is equipped with a clamping block for pushing the nut to connect with the fixed ring, and another end of the clamping mechanism is equipped with a positioning pin for limiting the clamping block.

[0007] By adopting the above technical solution, firstly, it can ensure that the nut can be accurately positioned and firmly clamped during the tapping process, guaranteeing the accuracy and stability of tapping and improving the quality and efficiency of nut processing; secondly, when the type of nut being processed changes, the retaining ring can be quickly replaced, thereby reducing equipment downtime and improving the tapping efficiency of the nut.

[0008] Optionally, the outer side of the fixing ring is provided with multiple fixing grooves for inserting nuts, the inner side of the fixing ring is fixedly connected with multiple positioning rods, and the outer side of the rotating disk is provided with positioning grooves for inserting multiple positioning rods.

[0009] By adopting the above technical solution, the accuracy and stability of the fixed ring installation on the rotating disk can be ensured, and displacement of the fixed ring during the tapping process can be avoided, thereby ensuring the machining accuracy of the nut.

[0010] Optionally, each of the fixed grooves has a through hole in its bottom wall that passes through the fixed ring, for the tapping drill bit to pass through.

[0011] By adopting the above technical solution, a channel can be provided for the tapping drill bit to pass directly through the retaining ring, enabling the tapping drill bit to accurately process the nut without the need for additional adjustment of the drill bit position, simplifying the operation process and improving processing efficiency.

[0012] Optionally, two locking components are provided. Each locking component includes a locking plate, a plug, and a return spring. Both ends of the rotating disk are provided with a sliding groove for the locking plate to slide.

The side of the locking plate away from the return spring is fixedly connected to one end of the plug. The inner side of the fixing ring is provided with a slot for one end of the plug to be inserted.

[0013] By adopting the above technical solution, the fixing ring can be firmly locked on the rotating disk, ensuring that the fixing ring will not loosen during processing. At the same time, the design of the return spring allows the locking part to automatically reset when the lock is released, making the operation more convenient and faster.

[0014] Optionally, two slide rods are fixedly connected to the inner side of each slide groove, and the two slide rods are respectively inserted through both ends of the locking plate.

[0015] By adopting the above technical solution, the sliding of the locking plate can be guided and limited, making the sliding of the locking plate more stable and accurate, and ensuring that the insert can stably extend out of the slide groove and insert into the inner wall of the slot.

[0016] Optionally, a push plate is fixedly connected to the upper end of the locking plate, and the push plate is slidably connected to the upper side of the rotating disk to block the upper end of the slide groove.

[0017] By adopting the above technical solution, dust or impurities generated during tapping of nuts can be prevented from entering the slide groove, thereby ensuring the normal operation of the locking components and improving the stability and reliability of the equipment.

[0018] Optionally, connecting rods for connecting the body are provided on both sides of the fixing ring, wherein the upper end of one of the connecting rods is fixedly connected to a push rod connected to the upper side of the fixing ring for pushing the nut away from the fixing ring, and the upper end of the other connecting rod is fixedly connected to a limit plate for restricting the connection between the nut and the fixing ring.

[0019] By adopting the above technical solution, the limiting plate can restrict the connection position between the nut and the retaining ring, ensuring the accurate placement of the nut in the fixing groove and further improving the processing accuracy; the push rod can push the nut away from the retaining ring, making it easier to remove the nut after processing.

[0020] Optionally, the clamping mechanism includes a hydraulic push rod, a movable block, and a mounting base. The hydraulic push rod is fixedly installed on the upper side of the machine body, and one end of the piston rod of the hydraulic push rod is fixedly connected to one side of the movable block. The mounting base is installed on the upper side of the movable block and is used for loading the clamping block.

[0021] By adopting the above technical solution, a stable clamping force can be provided to fix the nut in the fixing groove, ensuring the machining accuracy of the nut. Furthermore, the corresponding clamping blocks can be replaced according to the shape and size of the nut, thereby adapting to the machining needs of nuts of different specifications.

[0022] Optionally, one end of the mounting base is provided with a mounting groove for inserting one end of the clamping block, one end of the clamping block is provided with a positioning hole for the positioning pin to pass through, both ends of the positioning pin are inserted into the inner walls of both sides of the mounting groove, and one end of the positioning pin is connected to a latch for limiting the positioning pin.

[0023] By adopting the above technical solution, the clamping block can be installed quickly and accurately, ensuring the installation of the clamping block firmly and preventing it from loosening during processing, thereby guaranteeing the clamping effect of the nut and the processing quality.

[0024] Optionally, both ends of the movable block are slidably connected to limit rods, and both ends of the two limit rods are fixedly connected to a fixed rod fixedly connected to the upper side of the organism.

[0025] By adopting the above technical solution, the sliding of the movable block can be limited, preventing excessive sliding or displacement of the movable block during clamping, thus ensuring the stability and reliability of the clamping component.

[0026] In summary, this application has the following beneficial effects: 1. When the type or size of the nut being processed changes, the retaining ring and clamping block can be quickly installed or removed, reducing downtime and making the operation convenient, thereby improving the tapping efficiency of the nut.

[0027] 2. This application, through the cooperation of the rotating disk, the fixing ring and the locking component, can ensure that the nut is accurately positioned during the tapping process, and the clamping mechanism firmly clamps the nut in the fixing groove, which can effectively prevent the nut from shifting or loosening during the processing, thereby ensuring the accuracy and stability of tapping.

[0030] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0031] This application discloses a positioning device for a nut tapping machine.

[0032] Reference Figure 1The nut tapping machine positioning device includes a body 1, with a motor installed on the inner wall of the body 1. A positioning mechanism 2, fixedly connected to the motor output shaft, is located on the upper side of the body 1. A clamping mechanism 3 for fixing nuts is also installed on the upper side of the body 1. A guide rod 4, fixedly connected to the body 1, is located on one side of the positioning mechanism 2 to orderly convey nuts to the upper side of the positioning mechanism 2. The positioning mechanism 2 includes a rotating disk 21 fixedly connected to the motor output shaft and a fixing ring 22 installed on the outside of the rotating disk 21. The rotating disk 21 is driven to rotate by the motor inside the body 1, and the fixing ring 22 is used for inserting nuts. Locking elements 5 are installed at both ends of the rotating disk 21 to lock the fixing ring 22, ensuring the stability of the connection between the fixing ring 22 and the rotating disk 21. A clamping block 34 is installed at one end of the clamping mechanism 3 to push the nut to connect with the fixing ring 22. A groove matching the outer side of the nut is opened on one side of the clamping block 34 to improve the fixing effect of the nut. One end of the clamping mechanism 3 is equipped with a positioning pin 6 for limiting the clamping block 34, which is used to ensure the stability of the connection between the positioning pin 6 and the clamping mechanism 3.

[0033] In use, multiple nuts are first fed to the outside of the fixing ring 22 by the guide rod 4. Then, the rotating disk 21 is driven by the motor to rotate, which moves the nuts to one side of the clamping mechanism 3. Then, the clamping mechanism 3 is driven to run until one side of the clamping block 34 presses against one side of the nut, fixing the nut on the fixing ring 22 and completing the positioning of the nut so that the nut can be tapped.

[0034] Reference Figure 1 Connecting rods 8 are provided on both sides of the fixing ring 22, which are rotatably connected to the body 1. The upper end of one connecting rod 8 is fixedly connected to a push rod 9, which is connected to the upper side of the fixing ring 22. When the tapped nut contacts the push rod 9, it pushes the nut away from the fixing ring 22, thus completing the unloading of the nut. The upper end of the other connecting rod 8 is fixedly connected to a limit plate 10, which is used to prevent the nut from falling off during the rotation of the fixing ring 22 and the movement of the nut to one side of the clamping block 34.

[0035] Reference Figure 1 , Figure 2 and Figure 3The outer side of the retaining ring 22 has multiple retaining grooves 221 for inserting nuts, preventing the nuts from rotating during tapping. Multiple positioning rods 222 are fixedly connected to the inner side of the retaining ring 22. The outer side of the rotating disk 21 has positioning grooves 211 for inserting the positioning rods 222. The positioning grooves 211 are used for positioning the retaining ring 22. The connection between the positioning rods 222 and the inner wall of the positioning grooves 211 prevents the retaining ring 22 from rotating during equipment operation. Each retaining groove 221 has a through hole 223 penetrating the retaining ring 22 on its bottom wall, allowing the tapping drill bit to pass through, preventing damage to the retaining ring 22 during tapping and improving the service life of the equipment.

[0036] Reference Figure 3 , Figure 4 The locking element 5 has two parts, including a locking plate 51, an insert block 52 fixedly connected to one side of the locking plate 51, and a return spring 53 fixedly connected to the other side of the locking plate 51. Both ends of the rotating disk 21 have sliding grooves 212 for the locking plate 51 to slide, which limit the sliding range of the locking plate 51. Two sliding rods 54, passing through both ends of the locking plate 51, are fixedly connected to the inner wall of the sliding groove 212. The sliding rods 54 prevent the locking plate 51 from becoming misaligned during sliding. The other end of each return spring 53 is fixedly connected to one side of the inner wall of the sliding groove 212, and the elastic force of the return spring 53 can push the locking plate 51 to slide within the inner wall of the sliding groove 212. A push plate 54 is fixedly connected to the upper end of each locking plate 51. The push plate 54 pushes the locking plate 51 to slide within the sliding groove 212 and can also block the upper end of the sliding groove 212 to prevent dust or impurities from entering the sliding groove 212. The inner side of the fixing ring 22 is provided with a slot 224 for inserting one end of the plug 52. When the fixing ring 22 is connected to the rotating disk 21, the locking plate 51 is pushed to slide in the slide groove 212 by the return spring 53 until one end of the plug 52 extends out of the slide groove 212 and inserts into the inner wall of the slot 224, thereby locking the fixing ring 22 and preventing the fixing ring 22 from coming off the rotating disk 21.

[0037] Reference Figure 5 , Figure 6The clamping mechanism 3 includes a hydraulic push rod 31 fixedly connected to the machine body 1, a movable block 32 fixedly connected to one end of the piston rod of the hydraulic push rod 31, and a mounting base 33 fixedly installed on the upper side of the movable block 32. Fixed rods 12 arranged on both sides of the movable block 32 are fixedly connected to the upper end of the machine body 1. A limiting rod 11, which is slidably connected to the lower end of the movable block 32, is fixedly connected between the two fixed rods 12 to ensure the stability of the sliding of the movable block 32. The mounting base 33 is fixedly installed on the upper side of the movable block 32 by fasteners, and one side of the mounting base 33 has a mounting groove 331 for inserting one end of the clamping block 34 for positioning and installation. A positioning pin 6 passes through one end of the mounting base 33, and a positioning hole 341 is provided at one end of the clamping block 34 inserted into the mounting groove 331 for the positioning pin 6 to pass through, ensuring the stability of the connection between the clamping block 34 and the mounting base 33. A locking buckle 7 is provided at one end of the positioning pin 6. The locking buckle 7 is used to fix the positioning pin 6 between the mounting base 33 and the clamping block 34 to prevent the positioning pin 6 from falling off. In this application, the locking buckle 7 is a pin buckle. In other embodiments, the pin buckle can also be a nut, a retaining ring, or other types.

[0038] In use, the hydraulic push rod 31 pushes the movable block 32 to slide along the limit rod 11 until the clamping block 34 abuts against the outside of the nut, thereby fixing the nut in the fixing groove 221. When the clamping block 34 needs to be replaced, the locking buckle 7 is removed and the positioning pin 6 is pulled out to pull the clamping block 34 away from the mounting groove 331 of the mounting base 33. Then, the new clamping block 34 is inserted into the mounting groove 331 until it fits against the mounting base 33. At this time, the positioning pin 6 is inserted into the mounting base 33 and passes through the positioning hole 341. Then, the locking buckle 7 is inserted into one end of the positioning pin 6, thereby completing the replacement of the new clamping block 34.

[0039] The implementation principle of the nut tapping machine positioning device in this application embodiment is as follows: When in use, the first step is to feed the nut into the fixing groove 221 of the fixing ring 22 by the guide rod 4. At this time, the nut is placed in the fixing groove 221 one by one by the rotation of the rotating disk 21. Then, the limiting plate 10 prevents the nut from falling off the fixing ring 22 until the nut moves to one side of the clamping block 34. At this time, the rotating disk 21 stops rotating. Step 2: Start the hydraulic push rod 31 to push the movable block 32 to move along the limit rod 11 until one side of the clamping block 34 abuts against the outside of the nut, fixing the nut in the fixing groove 221. At this time, the tapping machine will tap the nut. After tapping is completed, control the hydraulic push rod 31 to retract. At this time, the rotating disk 21 continues to rotate until the nut contacts the push rod 9, so that the nut is separated from the fixing ring 22, and the nut is unloaded.

[0040] When it is necessary to replace the retaining ring 22, the first step is to push the push plate 54 to drive the locking plate 51 to slide in the slide groove 212 until the insert block 52 is disengaged from the slot 224. At this time, support the lower side of the retaining ring 22 and lift the retaining ring 22 upward until the retaining ring 22 is disengaged from the rotating disk 21, thus completing the disassembly of the retaining ring 22. Step 2: Align the positioning rod 222 on the inner side of the new fixing ring 22 with the positioning groove 211 on the outer side of the rotating disk 21, press the fixing rod 12 until the positioning rod 222 is fully inserted into the positioning groove 211. At this time, with the help of the elastic force of the return spring 53, push the locking plate 51 to slide on the inner wall of the slide groove 212 until the insert block 52 is inserted into the slot 224, thus completing the installation of the new fixing ring 22.

[0041] When it is necessary to replace the clamping block 34, the first step is to remove the latch 7 at one end of the positioning pin 6, and then pull one end of the positioning pin 6 to pull it away from the mounting base 33. At this time, pull one end of the clamping block 34 to drive one end of the clamping block 34 out of the mounting groove 331, thus completing the disassembly of the clamping block 34. Step 2: Insert one end of the new clamping block 34 into the mounting groove 331, and then pass the positioning pin 6 through the positioning hole 341 of the mounting base 33 and the clamping block 34 until one end of it extends out of the other end of the mounting groove 331. At this time, insert the latch 7 into one end of the positioning pin 6 so that the positioning pin 6 is fixed between the new clamping blocks 34, thus completing the installation of the new clamping block 34.

[0042] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
