These problems not only affect the product's appearance quality but can also lead to functional defects, increasing the defect rate and production costs. Therefore, improving the induction positioning accuracy of hydraulic motors in the production of threaded products has become a pressing technical challenge. Utility Model Content

[0019] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0020] Reference Figures 1 to 3 As shown, this utility model provides a threaded product forming device with adjustable sensing position. In one embodiment, it includes a fixed base 1, a lifting and rotating mechanism 2 mounted on the fixed base 1, and a first lifting rod 3 and a second lifting rod 4 connected to the lifting and rotating mechanism 2. The first lifting rod 3 is arranged inside the fixed base 1, and the upper part of the first lifting rod 3 extends movably from the top of the fixed base 1. A sensing element is also connected to the top of the first lifting rod 3. A first bracket 11 is installed on the top of the fixed base 1, and an adjusting slider 12 is slidably connected to one side of the first bracket 11. An upper sensor 13 is also installed on one side of the adjusting slider 12 in the vertical direction, and the upper sensor 13 is located above the sensing element. A lifting adjustment assembly connected to the adjusting slider 12 is also installed on one side of the first bracket 11. The second lifting rod 4 is arranged near one end of the fixed base 1, and the upper outer wall of the second lifting rod 4 is provided with an external thread 41 for forming the product.

[0021] Continue to refer to Figures 1 to 3As shown, in this embodiment, a pad 5 is also connected to the top of the fixed base 1. The first bracket 11 is screwed to one side of the pad 5. The upper part of the first lifting rod 3 moves through the fixed base 1 and the pad 5 in sequence. The lifting and rotating mechanism 2 can drive the first lifting rod 3 and the second lifting rod 4 to perform synchronous lifting and rotating movements. The upper outer wall of the second lifting rod 4 is provided with an external thread 41. Under the drive of the lifting and rotating mechanism 2, the upper part of the second lifting rod 4 can be inserted into the product and rotate inside the product to form an internal thread on the inner wall of the product through the external thread 41. At the same time, when the first lifting rod 3 drives the sensing element to the position of the upper sensor 13, the upper sensor 13 (position sensor) senses the signal. This indicates that the second lifting rod 4 has risen to its position (the product has already been formed; if it continues to rise, it will cause the rotating rod to burn out). The lifting and rotating mechanism 2 stops and begins to drive the first lifting rod 3 and the second lifting rod 4 to descend and reset. At the same time, if the position of the upper sensor 13 is not accurate enough and is in a low position, the sensor will already be against the upper sensor 13 before the second lifting rod 4 has risen to its position, and the lifting and rotating mechanism 2 will stop. At this time, the product may be burred because the second lifting rod 4 is not in position. Therefore, a lifting adjustment component is provided, which can drive the adjustment slider 12 to move according to actual usage needs, thereby adjusting the position of the upper sensor 13 to ensure the accuracy of product forming.

[0022] In one embodiment, a first sliding groove 14 is provided on one side of the first bracket 11 in the vertical direction; a guide block 15 is provided at one end of the adjusting slider 12, and the guide block 15 is movably inserted into the first sliding groove 14; the lifting adjustment assembly includes a fixing block 16 and an adjusting screw 17; the fixing block 16 is installed on one side of the first bracket 11 and located above the adjusting slider 12; a limiting groove 18 is provided at one end of the fixing block 16, and the threaded end of the adjusting screw 17 is screwed to the top of the adjusting slider 12, and the other end of the adjusting screw 17 is movably arranged in the limiting groove 18.

[0023] In this embodiment, the adjusting screw 17 is a hexagonal key rotating screw. By rotating the screw, the adjusting slider 12 is driven to move along the first slide groove 14, thereby adjusting the position of the upper sensor 13. Specifically, the adjustment can be turned into a fine adjustment by using one rotation of the screw as one thread pitch, which is divided into 360 thread pitches for adjustment. At the same time, one end of the adjusting slider 12 is also provided with a guide slide hole 19 extending to the other end in the vertical direction; a limiting screw 10 is also installed on one side of the first bracket 11, and the limiting screw 10 is arranged through the guide slide hole 19.

[0024] In one embodiment, the sensing element includes a sensing rod 31 arranged vertically and connected to the top of the first lifting rod 3, and a sensing block 32 connected to the top of the sensing rod 31; a first fixing plate 101 is also connected to one side of the adjusting slider 12, and an upper sensor 13 is located above the sensing block 32 and installed on the first fixing plate 101; a second fixing plate 102 is also connected to the lower part of one side of the first bracket 11, and a lower sensor 103 (position sensor) is also installed on the second fixing plate 102 vertically; the lower sensor 103 is arranged below the sensing block 32. By setting the upper and lower sensors 103, the lifting stroke of the first lifting rod 3 and the second lifting rod 4 can be limited to avoid excessive lifting.

[0025] In one embodiment, the lifting and rotating mechanism 2 includes a motor 21 mounted on a fixed base 1, a drive gear 22 arranged inside the fixed base 1 and mounted on the output shaft of the motor 21, a rotating shaft 23 arranged near one end of the fixed base 1, and a first driven gear 24 mounted on the rotating shaft 23 and meshing with the drive gear 22; a first mounting block 25 is also connected to the bottom of the fixed base 1, and a first nut seat 26 is also fixedly mounted on the first mounting block 25; the lower part of the first lifting rod 3 is screwed to the first nut seat 26, and a second driven gear 27 meshing with the drive gear 22 is also mounted in the middle of the first lifting rod 3; a second nut seat 28 is also fixedly mounted near the rotating shaft 23, and the lower part of the second lifting rod 4 is screwed to the second nut seat 28; a third driven gear 29 meshing with the drive gear 22 is also mounted in the middle of the second lifting rod 4; the lifting and rotating mechanism 2 also includes two bearings 20 arranged at intervals in the vertical direction, and the top and bottom of the rotating shaft 23 are respectively connected to a bearing 20. In this embodiment, a gear transmission method is used to drive the first lifting rod 3 and the second lifting rod 4 to perform synchronous lifting and rotating motion, which can ensure the stability of their movement.

[0026] In summary, this utility model can finely adjust the position of the upper sensor 13 through the lifting and adjusting component, thereby making the sealing position more precise and avoiding problems such as product burrs and burnt rotating rods. Its overall design is reasonable, compact, easy to use, and highly practical.
