[0019] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0020] In the description of this utility model, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections, electrical connections; direct connections, indirect connections through an intermediate medium, and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0021] Please see the attached Figure 1 -Attached Figure 2The present invention provides an embodiment of a turning machine rotation angle positioning assembly, comprising a turning spindle 1, a turning machine frame 2 is provided on one side of the turning spindle 1, the turning spindle 1 passes through the turning machine frame 2 and is rotatably connected to the turning machine frame 2 through a bearing, the outer surface of the turning spindle 1 and located on the side of the turning machine frame 2 away from the fixed shell 4 is transmission-connected with a first sprocket 7, the outer ring of the first sprocket 7 is meshed with a chain 8, the other end of the chain 8 is meshed with a second sprocket 9, the middle part of the second sprocket 9 is fixedly connected with an input shaft 10, the other end of the input shaft 10 is connected to a reduction motor (not shown in the figure), the input shaft 10 is connected to the reduction motor by a coupling, driving the second sprocket 9 to rotate, and the first sprocket 7 is driven by the chain 8 to rotate, thereby realizing the rotation of the turning spindle 1, and the turning spindle 1 is used to drive the turning machine to achieve a certain angle of rotation. Therefore, by fixing the induction shell of the angle positioning assembly to the turning spindle 1 so that they rotate synchronously, the angle of rotation of the turning machine can be directly obtained from the angle of rotation of the induction shell 3.

[0022] Specifically, because the installation space of the two groups of proximity switches is limited, the optimal flip angle that can be measured by the positioning component is 0°-210°.

[0023] An induction shell 3 is fixedly connected to one end of the flip spindle 1. The induction shell is made of metal material. A fixed shell 4 is coaxially arranged on the outside of the induction shell 3. The fixed shell 4 is fixedly connected to the flip machine frame 2. Two groups of slide grooves 41 are respectively provided on both sides of the fixed shell 4. The induction shell 3 is cylindrical. The induction shell 3 includes an induction cylinder 31 that is axially threaded with the flip spindle 1. A square hole 32 is provided on the side wall of the induction cylinder 31. The induction cylinder 31 is away from the end of the flip spindle 1 and is located on one side of the square hole 32. An arc-shaped induction plate 33 is integrally connected. The width of the square hole 32 is the same as the width of the arc-shaped induction plate 33. The square hole 32 and the slide groove 41 at one end close to the flip machine frame 2 are in the same vertical plane, and the arc-shaped induction plate 33 and the slide groove 41 at the end away from the flip machine frame 2 are in the same vertical plane.

[0024] Position sensing components 5 are detachably provided in the slide grooves 41 on both sides, wherein the position sensing components 5 include a normally open proximity switch 51 and a normally closed proximity switch 52. The normally open proximity switch 51 is located in the slide groove 41 at one end close to the turning machine frame 2, and the normally closed proximity switch 52 is located in the slide groove 41 at one end away from the turning machine frame 2. The normally open proximity switch 51 is open when no metal is detected and closed when metal is detected. Therefore, during the rotation process, when the detection probe is close to the wall of the sensing cylinder 31, the sensing circuit is in a closed state, allowing current to pass, thereby generating a signal output; when the detection probe is close to the square hole 32, the circuit is disconnected, no current passes, and therefore no signal output is generated.

[0025] On the contrary, the normally closed proximity switch 52 is closed when no metal is detected and is open when metal is detected. When the detection probe is close to a position other than the arc-shaped sensing plate 33, the sensing circuit is in a closed state, allowing current to pass, thereby generating a signal output; when the detection probe is close to the arc-shaped sensing plate 33, the circuit is disconnected, no current passes, and therefore no signal output is generated.

[0026] The controller processes these signals to determine whether the flip machine has flipped into place. By setting two position sensor components 5 in each group, it can also avoid the problem of positioning failure caused by damage to one of the sensors in a special environment, thereby providing double protection for the positioning work of the flip machine's rotation angle.

[0027] An installation assembly 6 is provided between the position sensing assembly 5 and the slide 41 for adjusting the angle between the two sets of position sensing assemblies 5 to adapt to the different angle changes required under different production conditions of the turning machine, so that a more precise turning angle can be positioned.

[0028] Furthermore, the mounting assembly 6 includes fixing plates 61 respectively arranged inside and outside the fixed shell 4, each fixing plate 61 is threadedly connected to the position sensing assembly 5, a protrusion 62 is provided between one fixing plate 61 and the inner wall of the fixed shell 4, and a recessed block 63 is provided between the other fixing plate 61 and the outer wall of the fixed shell 4, wherein the protrusion 62 and the recessed block 63 can be made of rubber material. After adjusting the position, the fixing plate 61 outside the fixed shell 4 is rotated, and the concave surface of the recessed block 63 can be in close contact with the fixed shell 4 with an annular appearance. The distance between the two fixing plates 61 gradually decreases, and the convex surface of the protrusion 62 is in close contact with the inner wall of the fixed shell 4, so that the position sensing assembly 5 is firmly fixed on the annular fixed shell 4.

The units described as separate components may or may not be physically separate, and the components shown as units may or may not be physical units, i.e., they may be located in one location or distributed across multiple network units.
