[0001] The invention belongs to the technical field of double-threaded connection joint processing, and in particular relates to a double-threaded connection joint processing device. Background Art

[0002] In the current field of double-threaded connection joint processing technology, double-threaded head refers to a spiral line with a specific cross-section of continuous raised spiral lines made on the surface of both ends of a cylindrical or conical bolt, which is used to connect bolts and nuts.

[0003] The current double-threaded connection joint processing uses a fixture to clamp the bar, and then uses a thread processing tool to contact the bar. The fixture holds the bar and rotates it, while also moving linearly to form a thread segment. When the head thread segment is processed, the tool is retracted, and the fixture holds the bar and moves a distance before re-entering the tool to process the tail thread segment. After processing is completed, the tool is retracted and the bar is cut off with a cutter before blanking. This results in a slow processing process and low efficiency. Summary of the Invention

DETAILED DESCRIPTION

[0032] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0033] See also Figure 1-4 The present invention provides a technical solution: a processing device for a double-headed threaded connection joint, comprising a base 1, a fixed base 2, a fixed base 3, a movable base 4, a connection joint 5 and a clamping device 6, a movable groove 101 is provided on the base 1, a slider 405 matching the movable groove 101 is installed on the lower surface of the movable base 4, the movable base 4 is slidably connected to the base 1 through the slider 405, and a threaded hole 406 is provided on the slider 405, a driving screw 407 matching the threaded hole 406 is rotatably installed in the movable groove 101, the driving screw 407 is driven and connected to the slider 405, and a driving motor 408 connected to the driving screw 407 is fixedly installed on the side wall of the base 1.

[0034] The driving motor 408 drives the driving screw 407 to rotate, thereby driving the slider 405 to move laterally in the moving groove 101, so as to facilitate the adjustment of the movement of the moving seat 4 and the position of the connecting joint 5.

[0035] The fixing seat 1 2 and the fixing seat 2 3 are both fixedly mounted on the upper surface of the base 1, a lifting rod 1 201 is mounted on the inner wall of the fixing seat 1 2, an adjusting member 1 202 which is transmission-connected to the lifting rod 1 201 is provided on the upper surface of the fixing seat 2, a movable frame 1 203 is transmission-connected to the lifting rod 1 201, a knife holder 204 is detachably mounted on the movable frame 1 203, and a processing knife 205 is detachably mounted on the lower surface of the knife holder 204.

[0036] Among them, the adjusting part 202 can drive the lifting rod 201 to move, and then adjust the lifting rod 201 to move longitudinally, and then drive the movable frame 203 to move longitudinally. When the movable frame 203 moves downward, it drives the tool holder 204 to move the processing tool 205, and processes the connecting joint 5 through the processing tool 205. When the movable frame 203 moves upward, the processing tool 205 is away from the connecting joint 5.

[0037] A lifting rod 2 301 is installed on the inner wall of the fixed seat 2 3, and an adjusting part 2 302 which is transmission-connected to the lifting rod 2 301 is provided on the upper surface of the fixed seat 2 3. A movable frame 2 303 is transmission-connected to the lifting rod 2 301, and a knife holder 2 304 is detachably installed on the movable frame 2 303. A processing knife 2 305 is detachably installed on the lower surface of the knife holder 2 304.

[0038] In addition, the lifting rod 2 301 can be moved by the adjusting part 2 302, and then the movable frame 2 303 can be moved up and down. The movable frame 2 303 descends, driving the processing knife 2 305 of the tool holder 2 304 to move, and the connecting joint 5 is processed by the processing knife 2 305. The movable frame 2 303 rises, and the processing knife 2 305 of the tool holder 2 304 rises, so that the processing knife 2 305 is kept away from the connecting joint 5, preventing the processing knife 2 305 from damaging the connecting joint 5.

[0039] A positioning sleeve 501 is sleeved on the connecting joint 5, and a sliding groove 1 206 and a sliding groove 2 306 for sliding connection with the positioning sleeve 501 are respectively opened on the fixing seat 1 2 and the fixing seat 2 3.

[0040] In addition, the positioning sleeve 501 can be slidably connected to the first slide groove 206 and the second slide groove 306. At the same time, the positioning sleeve 501 can be made into a connecting joint 5, thereby improving the positioning accuracy of the connecting joint 5 during processing.

[0041] A fixing sleeve 402 that matches the connecting joint 5 is fixedly installed on the upper surface of the movable seat 4. Two sliding grooves 401 are opened on the upper surface of the base 1. Support slide rods 403 are slidably connected in the two sliding grooves 401. Arc-shaped clamping plates 404 are installed on the two support slide rods 403.

[0042] Furthermore, the connecting joint 5 passes through the fixing sleeve 402 to limit the position of the connecting joint 5 and at the same time support the connecting joint 5. The two arc-shaped clamping plates 404 clamp the connecting joint 5 after the connecting joint 5 completely passes through the fixing seat 2, and then fix the connecting joint 5 to prevent the connecting joint 5 from moving and affecting the processing accuracy.

[0043] The clamping device 6 clamps the connecting joint 5 , and the clamping device 6 can be detachably mounted on the machine tool.

[0044] Specifically, the clamping device 6 can be a three-jaw chuck, a four-jaw chuck, etc., and the machine tool drives the clamping device 6 to rotate and drives the clamping device 6 to move axially, thereby driving the connecting joint 5 to move and perform thread processing on the connecting joint 5.

[0045] The working principle and use process of the present invention are as follows: after the present invention is installed, the machine tool drives the clamping device 6 to rotate, and drives the clamping device 6 to move axially, thereby driving the connecting joint 5 to move. When the connecting joint 5 passes through the fixed seat 2, the adjusting member 202 can drive the lifting rod 201 to move, and drive the movable frame 203 to move downward, and the connecting joint 5 is processed by the processing knife 205, and one end of the connecting joint 5 is threaded. At the same time, after the processing is completed, the movable frame 203 rises, and the processing knife 205 is away from the connecting joint 5, and the connecting joint 5 passes through the fixed sleeve 402 to limit the position of the connecting joint 5 to support the connecting joint 5. The two arc-shaped clamping plates 404 clamp the connecting joint 5 after the connecting joint 5 completely passes through the fixed seat 2, and then fix the connecting joint 5. After the connecting joint 5 completely passes through the fixing seat 2, the driving motor 408 drives the driving screw 407 to rotate, and then drives the slider 405 to move horizontally in the moving groove 101, so that the connecting joint 5 is aligned with the fixing seat 2 3, and the connecting joint 5 passes through the fixing seat 2 3. The clamping device 6 clamps the connecting joint 5, and drives the connecting joint 5 to rotate and axially pulls the connecting joint 5. At the same time, the adjusting part 2 302 drives the lifting rod 2 301 to move, drives the moving frame 2 303 to descend, and the processing knife 2 305 moves downward. The connecting joint 5 is processed by the processing knife 2 305. After the thread processing is completed, the moving frame 2 303 rises, and the knife seat 2 304 can rise the processing knife 2 305, so that the processing knife 2 305 is away from the connecting joint 5 to prevent the processing knife 2 305 from damaging the connecting joint 5, thereby completing the processing of the connecting joint 5.

[0046] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
