Description

Technical Field

[0001] The utility model relates to a tracking and positioning device for moving a workpiece. Background Art

[0002] During the production process, many moving workpieces need to accurately stop at a specified position to perform the next action. However, in some cases, due to the structure of the moving workpiece itself, it is not possible to directly measure and position it with a switch. The measurement and positioning methods such as laser are affected by the site and have high costs. Content of the Utility Model

[0003] In view of the above problems, the utility model provides a tracking and positioning device. When the moving workpiece comes into contact with the tracking and positioning device during the movement process, the tracking bracket on the tracking and positioning device moves together with the moving workpiece. By setting a detection switch, the position of the moving workpiece can be accurately positioned. By setting a spring, after the moving workpiece leaves, the tracking bracket can automatically reset to the initial position. The device does not require driving, and has the advantages of simple structure, convenient installation and adjustment, stable and reliable tracking and positioning, long service life, and low cost.

[0014] Further, the fixed frame includes a bottom plate and a vertical plate erected on the bottom plate, and the guide rail is arranged above the front side of the vertical plate; a reinforcing rib plate is arranged between the bottom plate and the rear side wall of the vertical plate.

[0015] Further, the proximity switch includes a first proximity switch and a second proximity switch, and the first proximity switch and the second proximity switch are arranged at intervals.

[0016] To achieve the above object, the tracking and positioning method of the present utility model includes the following steps:

[0017] When the moving workpiece is not in contact, the tracking bracket stays at the extended position under the action of the pneumatic spring and the adjusting bolt 1;

[0018] After the moving workpiece moves closer and contacts the second adjusting bolt, the tracking bracket moves together with the moving workpiece;

[0019] During the movement of the tracking bracket, the first proximity switch first senses the signal and outputs the first control signal; after finally stopping, the second proximity switch senses the signal and outputs the second control signal.

[0020] Further, the method further includes the following steps:

[0021] The position of the moving workpiece is observed by combining the scale and the pointer above.

[0022] Further, the method further includes the following steps: the moving workpiece reduces its moving speed after receiving the first control signal.

[0023] The position of this tracking and positioning device can be adjusted conveniently, and it can be applied to the automatic control and manual control of the moving workpiece 6.

[0028] The embodiments of the present utility model will be described in detail below with reference to the drawings.

[0029] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present utility model.

[0030] The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present utility model, unless otherwise specified, the meaning of "a plurality of" is two or more.

[0031] As Figures 1 to 4 shown, the tracking and positioning device of the present utility model at least includes: a fixed frame 1, a connecting bracket 2, a linear guide (assembly) 3, a scale 4, a pointer 5, a moving workpiece 6, an adjusting bolt 7, an adjusting bolt 8, a tracking bracket 9, an induction plate 10, a proximity switch 11, a proximity switch 12, a pneumatic spring 13, etc.
