Description

Technical Field

[0001] This utility model relates to the field of threaded sleeve processing technology, specifically to an external thread turning fixture for threaded sleeve processing. Background Technology

[0002] A threaded sleeve is a new type of internal threaded fastener suitable for threaded connections. It is screwed into and fastened in the threaded hole of one of the connected parts to form a standard internal thread. The bolt (or screw) is then screwed into it. It is also known as a threaded insert or simply a threaded sleeve. It is a spring-shaped concentric body with internal and external threads, precisely machined from high-strength, high-precision, and smooth-surfaced cold-rolled diamond-shaped stainless steel wire. It is mainly used to reinforce and protect the internal threads of low-strength materials. When machining a threaded sleeve with a die, a clamp is required to hold and limit the threaded sleeve.

[0003] Traditional clamps can only externally hold threaded sleeves, which prevents tapping at the clamping position. This necessitates secondary processing or turning to cut off the threaded sleeve, increasing the workload of workers and reducing processing efficiency. Therefore, they are not suitable for clamping and limiting, failing to meet customer needs. To address these issues, we propose an external thread turning clamp for threaded sleeve machining.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 A thread turning fixture for machining threaded sleeves includes a mounting plate 1, a positioning plate 2 fixedly connected to the top of the mounting plate 1, a movable frame 3 slidably connected to the outer surface of the positioning plate 2, a drive box 4 fixedly connected to the top of the movable frame 3, a positive and negative threaded rod 5 rotatably connected between the left and right sides of the inner cavity of the drive box 4 via bearings, a rectangular plate 6 threadedly connected to the left and right sides of the outer surface of the positive and negative threaded rod 5, a drive plate 7 fixedly connected to the front of the rectangular plate 6, a movable plate 8 slidably connected to the left and right sides of the front of the drive box 4, a horizontal plate 9 fixedly connected to the front of the movable plate 8, and a tensioning plate 10 fixedly connected to one side of the top of the horizontal plate 9.

[0021] In this embodiment: By setting up an installation plate 1, a positioning plate 2, a movable frame 3, a limiting bolt 11, and a pin hole 12, the device's height can be easily adjusted. By setting up a drive box 4, positive and negative threaded rods 5, a rectangular plate 6, a drive plate 7, a movable plate 8, a horizontal plate 9, and a tensioning plate 10, it is possible to easily internally tension and clamp threaded sleeves of different sizes. By setting up the above structure, the fixture has the advantage of easy tensioning, clamping, and limiting during use, solving the problem that traditional fixtures are not easy to clamp and limit during use, thereby reducing the labor intensity of workers and improving processing efficiency.

[0022] As a technical optimization of this utility model, the left and right sides of the movable frame 3 are threaded with limit bolts 11, and the left and right sides of the positioning plate 2 are evenly provided with pin holes 12, with one end of the limit bolt 11 extending into the inner cavity of the pin hole 12.

[0023] In this embodiment, by setting the limiting bolt 11 and the pin hole 12, the connection between the movable frame 3 and the positioning plate 2 can be conveniently limited.

[0024] As a technical optimization of this utility model, a guide plate 13 is fixedly connected to the bottom of the rectangular plate 6, and guide grooves 14 that cooperate with the guide plate 13 are opened on both the left and right sides of the bottom of the inner cavity of the drive box 4. The outer surface of the guide plate 13 is slidably connected to the inner surface of the guide groove 14.

[0025] In this embodiment, by setting the guide plate 13 and the guide groove 14, the rectangular plate 6 can be guided and limited.

[0026] As a technical optimization of this utility model, slide rails 15 are fixedly connected to the upper and lower positions of the front of the drive box 4, and the outer surface of the slide rails 15 is slidably connected to the inner surface of the movable plate 8.

[0027] In this embodiment: by setting the slide rail 15, the movable plate 8 can be easily guided and supported.

[0028] As a technical optimization of this utility model, the right end of the positive and negative threaded rod 5 passes through the drive box 4 and is fixedly connected to the handle 16, and a hexagonal groove 17 is opened on the right side of the handle 16.

[0029] In this embodiment: by setting the handle 16 and the hexagonal groove 17, it is possible to easily drive the forward and reverse threaded rod 5 to rotate using an external hexagonal wrench.

[0030] As a technical optimization of this utility model, the left and right sides of the front of the drive box 4 are provided with moving grooves 18 that cooperate with the drive plate 7, and the outer surface of the tension plate 10 is provided with anti-slip texture.

[0031] In this embodiment: by setting the moving groove 18, the drive plate 7 can be moved easily; by setting the anti-slip texture, the friction of the tension plate 10 can be improved, thereby improving the stability of the tension clamping.

[0032] As a technical optimization of this utility model, mounting holes 19 are provided at the four corners of the top of the mounting plate 1, and the mounting holes 19 are circular.

[0033] In this embodiment, the device can be easily installed by providing mounting holes 19.

[0034] Working principle: The operator uses the mounting hole 19 and screws to fix the device in the designated position. Then, when the operator needs to adjust the height of the tension plate 10 according to the actual use, the operator moves the movable frame 3 upward, which causes the drive box 4 to move upward. The drive box 4 causes the movable plate 8 and the horizontal plate 9 to move upward, which in turn causes the horizontal plate 9 to move the tension plate 10 upward. When the tension plates 10 on both sides move upward to the appropriate height, the movable frame 3 causes the limit bolts 11 to move to the corresponding pin holes 12. Then, the operator rotates the limit bolts 11 on both sides in sequence, so that the limit bolts 11 rotate and move on the inner surface of the movable frame 3 and insert into the inner cavity of the pin holes 12, thereby limiting the connection between the positioning plate 2 and the movable frame 3, and completing the adjustment of the height of the tension plate 10.

[0035] Next, the operator inserts threaded sleeves of different sizes into the outer sides of the tensioning plates 10 on both sides. Then, the operator moves the external hex wrench so that it is inserted into the inner cavity of the hexagonal slot 17. Then, the operator rotates the hex wrench, causing the handle 16 to rotate. The handle 16 causes the threaded rods 5 to rotate on the inner surfaces of the rectangular plates 6 on both sides. This causes the rectangular plates 6 to move the drive plate 7. The drive plate 7 causes the movable plate 8 to slide on the outer surface of the slide rail 15. At the same time, the movable plate 8 causes the horizontal plate 9 and the tensioning plate 10 to move and make tension contact with the inner surface of the threaded sleeve, thereby achieving internal tension clamping and limiting of the threaded sleeve. This makes it convenient for the operator to use a die to process the threaded sleeve from all directions. The device is simple to operate and easy to use for clamping and limiting, thereby reducing the labor intensity of the operator and improving the processing efficiency.

[0036] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
