DETAILED DESCRIPTION

[0048] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0049] Unless otherwise specified, directional words such as "upper, lower, left, right" are defined according to the directions indicated in the corresponding drawings, while "inner" and "outer" refer to the inner and outer contours of the corresponding components themselves. In addition, the terms "first", "second", etc. used in this disclosure are to distinguish one element from another, and do not have order and importance.

[0050] like Figures 1 to 10 As shown, an embodiment of the present disclosure provides a travel monitoring device 100, which can be used, for example, in a vehicle production mold system, such as a stamping mold system for a vehicle body component. Specifically, the travel monitoring device 100 of the present disclosure includes a seat, a first indicator 2, and a flexible connector 3. The first indicator 2 is rotatably disposed on the seat 1, and the first indicator 2 can be configured as a pointer, for example, and according to the specific structure of the travel monitoring device 100, the first indicator 2 can be directly mounted on the seat 1, or can be indirectly connected to the seat 1 through other components.

[0051] The flexible connector 3 includes a first end for connecting to the first indicator 2 and a second end for connecting to the movable part 210 of the mechanism to be monitored. The mechanism to be monitored here can be, for example, the aforementioned mold 200 for vehicle production, and the movable part 210 refers to a slider inside the mold 200. It should be noted that the mold 200 generally includes a mold body and a movable part 210, and the movable part 210 can move linearly under the drive of the driving mechanism 220 to drive the mold body to move between the initial position and the predetermined position.

[0052] The flexible connector 3 refers to a wire material that has a certain degree of flexibility and can be rolled up, such as a steel cable. The flexible connector 3 plays the role of transmitting power. The flexible connector 3 is pulled by the movable part 210, thereby driving the first indicator 2 to rotate. In order to ensure effective power transmission, the flexible connector 2 should always be in a tensioned state. This structure of using the flexible connector 2 to transmit the linear motion of the movable part 210 to the first indicator 2 and causing the first indicator 2 to rotate, thereby indicating the movement stroke of the movable part 210, is a purely mechanical mechanism, does not involve power supply and electrical signals, has good on-site adaptability, and has higher reliability than pure mechanical structures, and is not as susceptible to interference as electrical signals.

[0053] The first indicator 2 can rotate to have a first indication position and a second indication position. At the first indication position, the movable component 210 is in an initial state, and at the second indication position, the movable component 210 moves to a predetermined position. Specifically, the first indication position is the zero position when the movable component 210 is not working. The second indication position is pre-set according to the actual required stroke of the movable component 210. For example, the actual required stroke of the movable component 210 is different for different vehicle models. This can be achieved according to different rotation angles of the first indicator 2. The longer the predetermined stroke of the movable component 210, the greater the rotation angle of the first indicator 2.

[0054] When the first indicator 2 rotates to the second indicating position, it indicates that the movable part 210 of the mechanism to be monitored has moved to the predetermined position. In this way, through the stroke monitoring device 100 provided by the present disclosure, although the movable part 210 is hidden inside the mold, which is similar to the movable part 210 being hidden in a dark box and thus its movement stroke cannot be or is not easy to monitor, the monitoring result of the movement stroke of the movable part 210 can be reflected outside the mold through the rotation of the first indicator 2, and the operator can know whether the movable part 210 has moved to the predetermined position by observing whether the first indicator 2 rotates to the second indicating position.

[0055] The technical solution provided by the embodiment of the present disclosure may include the following beneficial effects: the stroke monitoring device 100 provided by the present disclosure configures the first indicator 2 to have a first indication position and a second indication position, and when the movable part 210 of the mechanism to be monitored moves, the flexible connecting member 3 is pulled, thereby driving the first indicator 2 to rotate, and when the first indicator 2 rotates to the second indication position, it indicates that the movable part 210 moves to the predetermined position. In this way, although the movable part 210 is hidden inside the mold 200, the result of the stroke monitoring can be reflected outside the mold 200 through the rotation of the first indicator 2, so that the operator can know whether the movable part 210 inside the mold 200 moves to the predetermined position through the rotation of the first indicator 2, reducing the risk of scrapping the processing parts caused by the inadequate movement of the movable part 210, and improving the yield of the product. In addition, the stroke monitoring device 100 provided by the present disclosure transmits the movement stroke of the movable part 210 to the first indicator 2 through the flexible connecting member 3, does not involve power supply and electrical signals, has good on-site adaptability, and has high reliability of pure mechanical structure.

[0056] The travel monitoring device 100 provided by the present disclosure may further include an elastic member 4, which is used to provide an elastic force for the first indicator member 2 to return to the first indication position. When the movable component 210 returns to the initial state from the predetermined position, the first indicator member 2 can automatically return to the first indication position, that is, return to the zero position under the action of the elastic member 4, without the operator manually dialing it back to the first indication position, and the degree of automation is higher. According to the different specific structures for realizing the rotation of the first indicator member 2, the elastic member 4 can be in different forms such as a coil spring or an angled torsion spring.

[0057] As an implementation method for realizing the rotation of the first indicator 2, Figure 3 As shown, the travel monitoring device of the present disclosure also includes: a first shaft 5 and a rotating body 6. The first shaft 5 is arranged on the base body 1. The rotating body 6 is rotatably arranged on the first shaft 5. Specifically, a bearing 51 is arranged between the rotating body 6 and the first shaft 5. The flexible connection member 3 is wound on the rotating body 6, wherein the rotating body 6 is rotated by pulling the flexible connection member 3, and the first indicator member 2 is arranged on the rotating body 6 and can rotate with the rotation of the rotating body 6. The specific power transmission path is: the linear motion of the movable part 210 pulls the flexible connection member 3, and the winding action of the flexible connection member 3 on the rotating body 6 drives the rotating body 6 to rotate, and the rotation of the rotating body 6 drives the first indicator member 2 to rotate. As shown Figure 7 As shown, the elastic member 4 can be constructed as a coil spring and is respectively connected to the rotating body 6 and the base body 1. The rotating body 6 and the base body 1 can be respectively provided with slots for fixing the two ends of the coil spring to prevent the coil spring from accidentally falling out during the compression process.

[0058] The rotating body 6 may be provided with a mounting shaft 63 at the rotating axis position, and the mounting shaft 63 is configured as a hollow shaft for the first shaft body 5 to pass through, and the first indicator 2 is provided on the mounting shaft 63. The first indicator 2 is provided with a mounting hole, and the mounting shaft 63 is also provided with a mounting hole, so that the first indicator 2 can be fixedly mounted on the mounting shaft 63 by bolts. The mounting shaft 63 can be integrally formed with the rotating body 6, which is conducive to saving the number of parts during assembly and improving assembly efficiency.

[0059] Also refer to Figure 4 and Figure 5 , a limiting member 7 may be provided at the first end of the flexible connector 3, and the flexible connector 3 may be connected to the limiting member 7 as a whole by, for example, welding. The limiting member 7 may be, for example, a cylindrical limiting block. The rotating body 6 includes a first limiting groove 611 and a first line groove 621. The first limiting groove 611 is provided on the end surface of the rotating body 6 for accommodating the limiting member 7; the first line groove 621 connects the first limiting groove 611 and the outer peripheral wall of the rotating body 6 for the flexible connector 3 to pass through. The width of the first line groove 621 is smaller than the radial dimension of the limiting member 7, so as to fix the end of the flexible connector 3 to the rotating body 6 and prevent the flexible connector 3 from being completely pulled out of the rotating body 6 during the winding process and being unable to continue to drive the rotating body 6 to rotate. When installing the flexible connector 3, firstly, the limiting member 7 is placed in the first limiting groove 611, and then the flexible connector 3 is wound on the outer peripheral wall of the rotating body 6 through the first line groove 621.

[0060] Optionally, the rotating body 6 can be constructed to include a disc-shaped main body 61 and limiting flanges 62 respectively arranged at both ends of the main body 61 along the axial direction. The flexible connector 3 is rolled up on the main body 61, and the limiting flange 62 protrudes radially from the outer peripheral wall of the main body 61. The first wire groove 621 is arranged on the limiting flange 62. In this way, the limiting flanges 62 at the axial ends of the main body 61 actually form a wire winding groove, which increases the winding space of the flexible connector 3 and can prevent the flexible connector 3 from slipping off the rotating body 6.

[0061] Also refer to Figure 1 and Figure 6 The seat body 1 can be constructed in a shell shape, including a housing cavity 122 for accommodating the rotating body 6 and an opening 121 arranged on the shell wall for the flexible connector 3 to pass through. Figure 3As shown, the seat body 1 can adopt a split design, that is, it includes an upper shell 11 and a lower shell 12, and the upper shell 11 and the lower shell 12 are buckled to form an accommodating space. This split design is conducive to the disassembly and maintenance of the internal parts of the seat body 1. The opening 121 is configured so that the exit point of the flexible connector 3 and the tangent line of the flexible connector 3 wound on the rotating body 6 are located on the same straight line. This design allows the flexible connector 3 to be pulled out or retracted from the seat body 1 more smoothly, thereby allowing the rotating body 6 and the first indicator 2 to respond more quickly to the power transmitted by the flexible connector 2, thereby improving the accuracy of monitoring.

[0062] The second end of the flexible connection 3 may be provided with a protective sleeve 8, which is used to prevent the flexible connection member 3 from directly contacting the seat body 1 with friction. The opening 121 includes a second limiting groove 1211 and a second line groove 1212. Among them, the protective sleeve 8 is at least partially accommodated in the second limiting groove 1211 in a shape-matching manner; the second line groove 1212 connects the second limiting groove 1211 and the accommodating cavity 122, and is used for the flexible connection member 3 to pass through. The second line groove 1212 is in shape with the flexible connection member 3 to prevent the flexible connection member 3 from moving in the second line groove 1212, and the width of the second line groove 1212 is smaller than the radial dimension of the protective sleeve 8, which can prevent the protective sleeve 8 from being accidentally brought into the seat body 1 during the winding process of the flexible connection member 3.

[0063] like Figure 2 and Figure 3 As shown, the travel monitoring device 100 provided by the present disclosure may also include a dial 101 disposed on the seat body 1, and a scale mark is disposed on the dial 101. The scale mark may be a scale value indicating a length, or a scale value indicating an angle. It is worth noting that if a scale value indicating an angle is used, it is necessary to convert the length of one circle of the flexible connection member 3 according to the diameter of the rotating body 6. The length of one circle of the flexible connection member 3 is the travel of the movable part 210 indicated by one circle of the first indicator 2, and then calculate the predetermined angle corresponding to the predetermined travel of the movable part 210, and the predetermined angle is the second indication position. By setting the dial 101, it is possible to more accurately determine whether the first indicator 2 has rotated to the second indication position.

[0064] The travel monitoring device 100 may also include a second indicator 9 rotatably arranged on the first shaft 5, the second indicator 9 is used to be set to a second indication position according to the predetermined travel of the movable part 210, and when the movable part 210 moves to the predetermined position, the first indicator 2 coincides with the second indicator 9. The second indicator 9 is arranged on the first shaft 5, that is, the second indicator 9 does not rotate with the rotating body 6. The purpose of setting the second indicator 9 is to calibrate the second indication position in advance, that is, the second indicator 9 is moved to the second indication position in advance before the mold works, so that it can be judged whether the movable part 210 moves to the predetermined position according to whether the first indicator 2 moves to a position that coincides with the second indicator 9. Compared with directly observing the position of the first indicator 2 marked with a scale on the dial 101, it is more intuitive and quick to observe whether the first indicator 2 coincides with the second indicator 9.

[0065] Furthermore, if Figure 3 As shown, the travel monitoring device 100 may further include a knob 52 disposed on the first shaft 5, and the knob 52 is fixedly connected to the second indicator 9 to drive the second indicator 9 to rotate. The second indicator 9 can be rotated more conveniently by the knob 52. In order to prevent the dial 101 from affecting the monitoring result due to the unexpected rotation of the second indicator 9, as shown in FIG. Figure 2 As described above, the outer peripheral edge of the dial 101 is provided with a first limiting portion 1011, and the seat body 1 is provided with a second limiting portion 13 for cooperating with the first limiting portion 1011 to limit the circumferential rotation of the dial 101. The first limiting portion 1011 can be a limiting protrusion, and the second limiting portion 13 is a limiting slot cooperating with the limiting protrusion. In addition, a protective cover 102 made of a transparent material can also be provided on the dial 101, and the position of the protective cover 102 corresponding to the knob 52 is a non-smooth surface, which is used to increase the friction between the protective cover 102 and the knob 52, so as to prevent the second indicator 9 from unexpectedly rotating and deviating from the predetermined position during the operation of the monitoring device.

[0066] In addition, the stroke monitoring device of the present disclosure may further include a reduction gear set disposed between the rotating body 6 and the first indicator 2, the reduction gear set including a first gear and a second gear meshing with each other, the purpose of which is to be able to expand to a larger monitoring stroke range, specifically, the number of teeth of the first gear is smaller than the number of teeth of the second gear, the first gear is connected to the rotating body 6, and the second gear is connected to the first indicator 2. That is, by utilizing the characteristic that the first gear rotates one circle while the second gear only rotates a small angle, a larger stroke of the movable component 210 can be monitored.

[0067] like Figures 8 to 10As shown, the present disclosure also provides another method for realizing the rotation of the first indicator 2. Specifically, the travel monitoring device also includes a second shaft body, and the second shaft body 14 is arranged on the base body 1. For example, the second shaft body 14 can be integrally formed on the base body 1. The first indicator 2 is rotatably arranged on the second shaft body 14. That is, different from the aforementioned embodiment including the rotating body 6, in this embodiment, the flexible connecting member 3 directly pulls the first indicator 2 to rotate. Specifically, the first indicator 2 indicates the end and the connecting end, and the first indicator 2 is installed on the base body 1 through the second shaft body 14 at the middle position of the indicating end and the connecting end, and a threaded component 15 is arranged at the connecting end, and the flexible connecting member 3 is connected to the first indicator 2 through the threaded component 15. Among them, the flexible connecting member 2 is wound on the stud and is tightened between the nut and the first indicator 2 by the nut. The elastic member 4 is a torsion spring and is connected to the base body 1 and the first indicator 2 respectively, wherein the torsion spring is wound on the second shaft body 14. The seat body 1 is provided with a first stop surface 16 and a second stop surface 17 for stopping two angled deformation portions of the torsion spring so as to compress the torsion spring when the first indicator 2 rotates.

[0068] A second object of the present disclosure is to provide a vehicle production mold system, such as Fig.11 As shown, it includes a mold 200 and a travel monitoring device 100, wherein the mold 200 includes a movable part 210 and a driving mechanism 220 for driving the movable part 210 to move. The travel monitoring device 100 is the travel monitoring device in any of the above embodiments, wherein the second end of the flexible connector 3 of the travel monitoring device 100 is connected to the movable part 210.

[0069] Furthermore, the mold may be an upper mold. In vehicle production, especially when a set of molds is used for different vehicle models, the upper mold has different movement strokes, so monitoring the movement stroke of the upper mold is particularly important. This can be achieved by connecting the flexible connector 3 of the stroke monitoring device 100 provided by the present disclosure to the movable part 210 of the upper mold.
