Description

Technical Field

[0001] This utility model relates to the field of wire threading groove forming technology, and in particular to a wire threading groove forming device for annular tube assembly. Background Technology

[0002] After precision cutting and processing, the annular tubular metal material is threaded through the inner side of the near end of the annular tube and welded to the far end. To ensure the accuracy of the bending angle and position of the annular tube, the traction rope inserted into the annular tube needs to be longitudinally positioned to reduce fluctuations. This is achieved by intermittently adding threading grooves longitudinally on the annular tube. The traction rope is threaded through the grooves and then connected. This ensures that a single traction rope is always stretched in one direction. For bending in different directions, grooves need to be made in different directions to achieve the required angle and position under different traction rope tensions. Regarding the annular tube groove forming, the current production method involves placing the cut annular tube into a mold and then pressing it on a press to form the grooves one by one. However, because there are many grooves on a single annular tube, and because the annular tube is small, and the placement is determined manually by visual inspection, the consistency of groove forming is poor, the pass rate is low, and the production efficiency is low. Utility Model Content

[0003] The purpose of this invention is to overcome the defects of the prior art by providing a ring tube assembly threading slot forming device that ensures the consistency of slot forming; adapts to the precise forming of each ring tube, ensuring the qualified rate of slot forming; simplifies operation; and improves overall efficiency.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0005] This utility model provides a wire-threading groove forming device for annular tube assembly, including: a machine base, an X-axis moving axis, a Y-axis moving axis, a Z-axis moving axis, a work platform, groove pressing pins, and an image capture assembly;

[0006] The X-axis, Y-axis, and Z-axis are positioned according to the required points set by computer software; the slot pressure pin is located on the Z-axis.

[0007] The working platform includes: a workbench, an X-axis positioning block, a Y-axis positioning block, and a fixture; the fixture is used to install the annular pipe, the fixture is placed on the workbench, and the fixture is attached to the X-axis positioning block and the Y-axis positioning block;

[0008] The tooling includes: a tooling base plate, a V-groove on the base plate, a mold core, an annular tube, an annular tube slot, an annular tube positioning piece, a mold core positioning pin slot, a mold core positioning pin, and a fixing elbow clamp.

[0009] The mold core is machined to fit the shape and size of the annular tube, and the mold core is equipped with an annular tube positioning plate and a mold core positioning pin; the fixed elbow clamp is used to fix the mold core; the tooling base plate is provided with a mold core positioning pin groove and a base plate V-groove; the annular tube is provided with an annular tube clamping groove.

[0010] Furthermore, a safety cover is also provided on the outside of the device.

[0011] Furthermore, the slot pressure pin is located at the end of the Z-axis moving shaft.

[0012] Furthermore, the image capture component is used to capture the situation of the slot and feed it back to the computer software program for precise shaping of the slot.

[0013] Furthermore, a control cabinet is also provided at the bottom of the machine.

[0014] Furthermore, the fixed elbow clamp is connected to the mold core pressure block and is used to press down the mold core measuring end.

[0015] Furthermore, the image capture component includes: a camera, a display, and a capture card; the camera is aimed at the fixture, the display is connected to the camera, and the capture card is connected to both the camera and the display.

[0016] Furthermore, the X-axis, Y-axis, and Z-axis are driven by motors.

[0017] Furthermore, the tooling can accommodate two annular tubes.

[0018] Furthermore, the image capture component is located on the Z-axis of movement.

[0019] The working principle is as follows:

[0020] Install the ring tube: First, insert the ring tube slot end of the ring tube into the far end of the mold core positioning pin on the mold core, and then insert the ring tube slot to the bottom of the ring tube positioning piece. Insert the installed ring tube and mold core together, and insert the mold core positioning pin along the mold core positioning pin slot on the tooling base plate to the bottom. Then, press down the fixed elbow handles on both sides in sequence to make the mold core pressure block press down on the mold core measuring end.

[0021] Place the fixture with the annular tube installed in the positioning area of ​​the worktable, close to the X-axis and Y-axis positioning blocks. Using the equipment's computer software, position the required multi-point slots via image capture using the X-axis, Y-axis, and Z-axis moving axes. After precise positioning, set the slot forming program. Following the automatic program execution, the slot pressing pins on the Z-axis will sequentially and continuously form slots on the annular tube, thus completing the slot formation in one direction in a single operation. The formed slots are wide enough for the traction rope to pass through.

[0022] Generally, annular tubes require bending in two or more directions. Therefore, if there are requirements in other directions according to the product design, the groove can be formed again after adjusting the angle of the mold core on the annular tube as a whole.

[0023] Compared with the prior art, the present invention has the following advantages:

[0024] (1) The structure of this device ensures the consistency of each slot by reliably positioning the annular tube and tooling and using high-precision control of the three-axis moving axis. It changes the current production method that relies on manual visual placement and manual operation to form the slots one by one by the pressure needles. It solves the problem of poor consistency of slot forming due to the large number of slots on the annular tube, the small size of the annular tube, and reduces the labor intensity of the operators.

[0025] (2) By configuring image capture function on the basis of precision three-axis moving axis, the image capture positioning is used to memorize each slot of the annular tube, and then the slots of the annular tube are formed sequentially according to the memorized position through the three axes. This avoids human factors in slot forming, makes up for the impact of fluctuations in the size of the annular tube itself, achieves precise forming of each annular tube, and ensures the qualified rate of slot forming.

[0026] (3) To produce high-quality products at a lower cost, two annular tubes are installed simultaneously for slot forming. A single program run can complete two products at the same time, and the manual clamping and slot forming are matched in time, maximizing efficiency. At the same time, due to the simplification of operation and the solution of the molding consistency problem, the overall efficiency is improved by more than 100%. Attached Figure Description
