Abstract
Description
Technical Field
[0001] The present application belongs to the technical field of cold rolling mills, and more specifically, to a two-degree-of-freedom mechanical tube end detection mechanism. Background Art
[0002] The cold rolling mill is a widely used equipment for metal forming processing, mainly used to produce metal pipes of various specifications. During the working process of the cold rolling mill, accurate detection of the end of the blank tube is conducive to improving the cold rolling forming quality of the tube.
[0003] In a fully automatic tube rolling mill, the tube end detection generally adopts the method of electromagnetic induction comparison circuit; that is, a tube seam detector is installed on the outside of the core. When the blank tube is sleeved on the core rod and passes through the tube seam detector, the blank tube covers the core rod, and the tube end position is judged by weakening the magnetic field (copper tube, stainless steel tube) or strengthening the magnetic field (carbon steel tube). Since there are many high-power electrical appliances on the cold rolling tube mill, the electromagnetic interference is large, and the hidden danger of tube end detection failure is large. At the same time, the vibration generated on the tube blank during tube rolling is also easy to cause damage and failure of the detection equipment, and the service life is short; therefore, it is necessary to solve the above technical problems. Summary of the invention
[0004] The purpose of the embodiments of the present application is to provide a two-degree-of-freedom mechanical pipe end detection mechanism to solve the technical problem of short service life of pipe end detection equipment in the prior art.
[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is: to provide a two-degree-of-freedom mechanical pipe end detection mechanism, including:
[0006] A first connecting seat;
[0007] A second connecting seat, rotatably connected to the first connecting seat;
[0008] A rotating shaft, passing through the second connecting seat and being rotatable relative to the second connecting seat, wherein a rotating axis of the rotating shaft and a rotating axis of the second connecting seat are perpendicular to each other;
[0009] Two collision flaps are connected to the rotating shaft at intervals and can rotate along with the rotating shaft;
[0010] A collision plate connected to the collision flap and used to be arranged on the side of the core rod;
[0011] The induction switch is spaced apart from the end of the rotating shaft and is used to detect the position of the rotating shaft.
[0012] Optionally, the collision flap is detachably connected to the rotating shaft and can adjust its relative position to the rotating shaft along the axial direction of the rotating shaft.
[0013] Optionally, the collision flap is connected to the rotating shaft by bolts, and the rotating shaft has a cut surface for abutting against the end of the bolt.
[0014] Optionally, the collision plate corresponds to a side of the core rod and gradually moves away from the core rod in a direction in which its own height decreases.
[0015] Optionally, the collision plate is detachably connected to the collision flap.
[0016] Optionally, the two-degree-of-freedom mechanical tube end detection mechanism further includes a column for mounting on the cold rolling mill body and a crossbeam connected to the column;
[0017] Two upright posts are arranged at intervals, the crossbeam is placed horizontally between the two upright posts, and the first connecting seat is installed at the middle position of the crossbeam.
[0018] Optionally, the two-degree-of-freedom mechanical pipe end detection mechanism further includes an induction switch seat clamped on the crossbeam and capable of rotating around the central axis of the crossbeam;

[0023] The beneficial effect of the two-degree-of-freedom mechanical pipe end detection mechanism provided by the present application is that: compared with the prior art, the second connection seat in the present application is rotatably mounted on the first connection seat, the rotating shaft is rotatably mounted on the second mounting seat, and the rotation axis of the rotating shaft is perpendicular to the rotation axis of the second mounting seat, so that the collision flap and the collision plate connected to the rotating shaft have freedom in two rotation directions and can rotate more smoothly in space. After the core rod drives the tube blank into the cold rolling mill, the collision between the tube blank and the collision plate will cause the collision flap to rotate around the central axis of the rotating shaft on the one hand, and can also rotate around the rotation axis of the second rotating seat, automatically adapting to the vibration of the tube blank in all directions, effectively avoiding damage to the tube blank detection mechanism, and significantly improving the service life of the tube end detection equipment, which is far superior to the prior art.

[0032] Please also read Figure 1 and Figure 2 Now, a two-degree-of-freedom mechanical pipe end detection mechanism provided in an embodiment of the present application is described. The two-degree-of-freedom mechanical pipe end detection mechanism includes a first connection seat 101, a second connection seat 102, a rotating shaft 103, a collision flap 104, a collision plate 105 and an induction switch 106. Among them:
[0033] The second connection seat 102 is rotatably connected to the first connection seat 101, the rotating shaft 103 passes through the second connection seat 102 and can rotate relative to the second connection seat 102, and the rotation axis of the rotating shaft 103 is perpendicular to the rotation axis of the second connection seat 102. As a preferred embodiment, this embodiment is described by taking the rotation axis of the rotating shaft 103 being perpendicular to the rotation axis of the second connection seat 102 as an example. Two collision flaps 104 are connected to the rotating shaft 103 at intervals and can rotate with the rotating shaft 103. The collision plate 105 is connected to the collision flap 104 and is used to be set on the side by side side of the core rod 201, and has an adaptive gap with the outer diameter of the core rod 201. The induction switch 106 is set at intervals from the end of the rotating shaft 103 and is used to detect the position of the rotating shaft 103.
[0034] According to the above structure provided in this embodiment, since the second connecting seat 102 is rotatably installed on the first connecting seat 101, the rotating shaft 103 is rotatably installed on the second mounting seat and the rotation axis of the rotating shaft 103 is perpendicular to the rotation axis of the second mounting seat, the collision flap 104 and the collision plate 105 connected to the rotating shaft 103 have freedom in two rotation directions and can rotate more smoothly in space. After the core rod 201 drives the tube blank 202 into the cold rolling mill, since the tube blank 202 is sleeved outside the core rod 201, the end face of the tube blank 202 will collide with the flap 104. The collision between the tube blank 202 and the collision plate 105 will cause the collision flap 104 to be able to rotate around the central axis of the rotating shaft 103 to trigger the sensor switch 106 to detect the position of the tube end, and to rotate around the rotation axis of the second rotating seat. In this way, the vibration generated by the tube blank 202 can be adaptively offset, and the damage to the detection mechanism by the tube blank 202 is effectively avoided, which significantly improves the service life of the tube end detection equipment. Since the amplitude of the tube blank vibration is much smaller than the difference between the outer diameter of the tube blank 202 and the core rod 201, the tube end detection mechanism has strong anti-interference ability and high detection accuracy during tube end detection. At the same time, it also has the characteristics of long service life and good reliability, which is far superior to the existing technology.
[0035] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The collision flap 104 is detachably connected to the rotating shaft 103 and can adjust its relative position with respect to the rotating shaft 103 along the axial direction of the rotating shaft 103. According to the above structure provided in this embodiment, since the collision flap 104 can adjust its relative position with respect to the rotating shaft 103 along the axial direction of the rotating shaft 103, the two-degree-of-freedom mechanical tube end detection mechanism provided in this embodiment can be used for end detection of tube blanks 202 of different sizes, and has a wider range of applications.
[0036] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The collision flap 104 is connected to the rotating shaft 103 by bolts, and the rotating shaft 103 has a cut surface 107 for abutting against the end of the bolt. According to the above structure provided in this embodiment, due to the cut surface 107 provided on the rotating shaft 103, when the collision flap 104 is connected to the rotating shaft 103 by bolts, it can be more stably connected to the rotating shaft 103.
[0037] In another embodiment of the present application, please refer to Figure 1 and Figure 2, the collision plate 105 gradually moves away from the core rod 201 along the direction of its own height decrease on one side corresponding to the core rod 201. According to the above structure provided in this embodiment, when the tube blank 202 fed by the core rod 201 collides with the collision plate 105, it can be guided by the inclined surface formed by the collision plate 105 and move relative to the inclined surface to avoid hard contact with the collision plate 105, further improving the service life of the two-degree-of-freedom mechanical tube end detection mechanism provided in this embodiment.
[0038] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The collision plate 105 is detachably connected to the collision flap 104. According to the above structure provided in this embodiment, when the collision plate 105 is damaged and needs to be repaired or replaced, it can be easily removed from the collision flap 104 for repair and replacement, thereby reducing the use cost of the two-degree-of-freedom mechanical pipe end detection mechanism provided in this embodiment.
[0039] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The two-degree-of-freedom mechanical tube end detection mechanism also includes a column 108 for installation on the cold rolling mill body and a crossbeam 109 connected to the column 108. Two columns 108 are arranged at intervals, and the crossbeam 109 is horizontally placed between the two columns 108. The first connecting seat 101 is installed in the middle position of the crossbeam 109. According to the above structure provided in this embodiment, the column 108 can be used to stably fix the crossbeam 109 and the first mounting seat and facilitate the first mounting seat to be arranged on the cold rolling mill to be more suitable for the position of the tube blank 202, which has a flexible use effect.
[0040] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The two-degree-of-freedom mechanical pipe end detection mechanism also includes an induction switch seat 110 clamped on the crossbeam 109 and capable of rotating around the central axis of the crossbeam 109, and the induction switch 106 is installed on the induction switch seat 110. According to the above structure provided in this embodiment, since the induction switch 106 is installed on the induction switch seat 110 and the induction switch seat 110 can rotate relative to the crossbeam 109, the relative position relationship between the induction switch 106 and the rotating shaft 103 can be flexibly adjusted by setting the induction switch seat 110, which is conducive to the two-degree-of-freedom mechanical pipe end detection mechanism provided in this embodiment being more flexibly adjusted to the detection accuracy required by the designer, and has good flexibility in use.
[0041] In another embodiment of the present application, please refer to Figure 1 and Figure 2, a clamping ring 111 is provided on the rotating shaft 103 for limiting the axial movement of the second connecting seat 102 relative to the rotating shaft 103. According to the above structure provided in this embodiment, the axial movement of the rotating shaft 103 relative to the second connecting seat 102 can be prevented by providing the clamping ring 111, so that the collision plate 105 can be stably maintained at the preset position for a long time, which is conducive to the long-term stable operation of the two-degree-of-freedom mechanical pipe end detection mechanism provided in this embodiment.
[0042] In another embodiment of the present application, please refer to Figure 1 and Figure 2 The first connection seat 101 is also provided with a locking nut 112 for limiting the axial clearance of the second connection seat 102 relative to the first connection seat 101. According to the above structure provided in this embodiment, the locking nut 112 can keep the second connection seat 102 on the first connection seat 101 on the one hand, and can also reserve a rotation clearance for the second connection seat 102 relative to the first connection seat 101 on the other hand, so as to ensure that the second connection seat 102 can rotate smoothly. Further, in another embodiment of the present application, please refer to Figure 1 and Figure 2 The locking nuts 112 are provided with two mutually self-locking ones, so that the axial clearance of the second connecting seat 102 relative to the first connecting seat 101 remains stable, thereby ensuring that the second connecting seat 102 can rotate flexibly relative to the first connecting seat 101.
[0043] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
