Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a precision positioning fixture for optical inspection. Background Technology

[0002] After the parts are manufactured, they need to be optically inspected to ensure product quality. Taking copper tubes as an example, their cross-sections need to be inspected for outer and inner diameters, thickness, number of teeth, and tooth angle, etc. The fixation of the copper tube is particularly important during the inspection process. The stability of the copper tube needs to be ensured during the optical inspection. At the same time, since copper tubes come in various specifications, a fixture that can be applied to various specifications needs to be designed. Utility Model Content

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0025] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the present invention. To better illustrate the embodiments of the present invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings.

[0026] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "inner," and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this utility model. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0027] See Figures 1 to 3 As shown, a precision positioning fixture for optical inspection includes: a support member 100, which supports a positioning member 200, a limiting member 300, and the part to be clamped; preferably, the support member 100 is a plate-like structure; a positioning member 200, disposed on the upper end of the support member 100, with a plurality of positioning grooves 201 evenly recessed along the circumference of the positioning member 200; preferably, the positioning member 200 is a cylindrical structure; a limiting member 300, disposed on the upper end of the support member 100 and located outside the positioning member 200; preferably, the limiting member 300 is an annular structure; and a plurality of clamping members 400 are provided on the sidewall of the limiting member 300, the clamping members 400 being rotatably connected to the limiting member 300 and their ends extending into the interior of the limiting member 300, with the ends of the clamping members 400 approaching... The positioning groove 201 moves in a direction to make the part to be clamped in close contact with the positioning groove 201. In the above technical solution, the part to be clamped can be cylindrical, tubular, triangular or other shapes. For ease of understanding, this solution takes a tubular part as an example. The part to be clamped is placed inside the limiting member 300 (i.e., outside the positioning groove 201). The bottom of the part to be clamped can be supported by the supporting member 100. Then, by rotating the clamping member 400, the end of the clamping member 400 moves inward continuously, thereby pushing the part to be clamped to move in the direction of the positioning groove 201 until the part to be clamped is in close contact with the positioning groove 201, thus realizing the clamping process of the part to be clamped. This technical solution can adapt to workpieces of different sizes and shapes by rotating the clamping member 400, ensuring the stability of the position of the part to be clamped during the inspection process and improving accuracy and efficiency.

[0028] As a preferred embodiment of this technical solution, a multi-axis slide table is also included, which is disposed at the lower end of the support member 100; as a preferred embodiment of the multi-axis slide table, the multi-axis slide table is an XY dual-axis slide table; in the above technical solution, the clamp is fixed on the electric XY dual-axis slide table, which is a device that can accurately control the movement of the object in the X and Y axes. After the clamping process is completed, the movement of the part is realized by controlling the operation of the XY slide table to facilitate multi-directional observation and inspection of the clamped part.

[0029] See Figure 1 As shown, the positioning groove 201 is a "V" shaped groove. As a preferred embodiment, the included angle of the positioning groove 201 is 30 degrees to 150 degrees, preferably 100 degrees. In the above technical solution, the positioning groove 201 with the "V" shaped structure design can better limit the position of the part to be clamped. Together with the clamping component 400, the part to be clamped can be clamped better, making it more stable and reliable in subsequent observation and testing.

[0030] See Figure 1 and Figure 3 As shown, the clamping member 400 includes a tightening section 401, a threaded section 402, and a clamping section 403 arranged sequentially. The tightening section 401 is located outside the limiting member 300, and the clamping section is located inside the limiting member. In the above technical solution, the side wall of the limiting member 300 is provided with multiple threaded holes, and the threaded section 402 of the clamping member 400 is threadedly connected to the limiting member 300 through the threaded holes. The tightening section 401 is used for manually rotating the clamping member 400. The end of the clamping member 400 is the end of the clamping section 403. This technical solution mainly relies on the clamping section 403 to apply a pushing force to the part to be clamped so that the end of the clamping section 403 and the positioning groove 201 clamp the part to be clamped.

[0031] As a further preferred embodiment, the clamping member 400 also includes a locking nut, which is screwed onto the threaded section 402 and located outside the limiting member 300. The locking nut is used to prevent the clamping member 400 from loosening. In this technical solution, although the clamping member 400 has a threaded section 402, it is prone to loosening during the use of the entire fixture, which can cause the threaded section 402 to loosen. This can cause the part to be clamped to loosen, thus affecting observation and inspection. Therefore, after the clamping section 403 of the clamping member 400 has completed the clamping process of the part to be clamped, the locking nut is rotated to make the locking nut and the limiting member 300 come into close contact, so that the clamping member 300 can be locked and prevented from loosening.

[0032] See Figure 1 and Figure 3As shown, the end of the clamping section 403 is a hemispherical structure; the design of the hemispherical structure can not only ensure the clamping effect, but also avoid damage to the clamped parts.

[0033] The above are merely preferred embodiments of this utility model, but the scope of protection of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this utility model, based on the technical solution and inventive concept of this utility model, should be included within the scope of protection of this utility model.
