[0031] In order to make the purpose, technical solution and advantages of the technical solution of the utility model clearer, the technical solution of the embodiment of the utility model will be clearly and completely described in conjunction with the drawings of the specific embodiments of the utility model. The same figure marks in the drawings represent the same parts. It should be noted that the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the described embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] Compared with the embodiments shown in the drawings, feasible implementations within the scope of protection of the present invention may have fewer components, other components not shown in the drawings, different components, differently arranged components, or differently connected components, etc. In addition, two or more components in the drawings may be implemented in a single component, or a single component shown in the drawings may be implemented as multiple separate components.

[0033] Unless otherwise defined, the technical terms or scientific terms used herein shall have the usual meanings understood by persons with ordinary skills in the field to which the utility model belongs. The words "first", "second" and similar words used in the specification and claims of the utility model patent application do not indicate any order, quantity or importance, but are only used to distinguish different components. Similarly, words such as "one" or "one" do not necessarily indicate quantity restrictions. Words such as "include" or "comprise" mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. Words such as "connect" or "connected" are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative positional relationships.

[0034] The utility model proposes a tool capable of simultaneously measuring the apertures of the upper and lower surfaces, which is used in the product inspection process. The utility model does not limit the type of product, but the structure of the tool capable of simultaneously measuring the apertures of the upper and lower surfaces is particularly suitable for the need to inspect the relative sides.

[0035] In general, the tooling capable of simultaneously measuring the apertures of the upper and lower surfaces proposed in the present invention mainly comprises a base 1, a product positioning seat 2, a top aperture measuring unit, and a top aperture measuring unit. Figure 1 , which shows the arrangement relationship of the base 1, the product positioning seat 2, the top aperture measurement unit, and the top aperture measurement unit.

[0036] In order to achieve the purpose of adapting different molding machines to the same mold, and to solve the problem that the existing fixtures for detecting the aperture of parts in the background technology all rely on conventional structures, and can only measure the aperture on the same side of the structure. When measuring the opposite side, the workpiece needs to be flipped. The flipping structure is complicated and will also lead to increased costs, which will require more time and manpower to adjust and calibrate the position of the product. Once inaccurate positioning occurs during the processing, it will affect the subsequent processing accuracy and product quality. For this reason, in the technical solution provided in this embodiment, a top aperture measurement unit and a top aperture measurement unit are integrated on the base 1, which does not affect the installation of the product to be inspected, ensures the installation alignment, and can also quickly detect the top and bottom at the same time.

[0037] like Figure 1The base 1 is installed on the operating table through a positioning unit, and a product positioning seat 2 is installed on the machine base 1. Since the product has concave arc structures on both sides, in order to achieve the need for rapid alignment and installation of the product, limiting grooves 3 are symmetrically arranged on both vertical side surfaces of the product positioning seat 2; in addition, in order to ensure the accuracy of the relative position between the machine base 1 and the top aperture measuring unit, the base 1 is installed on the operating table through a positioning unit. The positioning unit includes three consecutive groups of positioning blocks 5 installed around the base 1. Bolts are passed through the positioning blocks 5 to connect with the base 1 and the operating table. During installation, since the positioning block 5 adopts a circular setting, positioning connection holes 6 and positioning alignment holes 7 are respectively arranged around the central bolt hole 8, and the positioning connection holes 6 and the positioning alignment holes 7 can achieve the effect of precise installation.

[0038] As described above, the present embodiment provides a bottom aperture measuring unit for measuring the bottom aperture of a product. The bottom aperture measuring unit includes a measuring mounting seat 9 and a No. 2 positioning pin 10. A through hole with the No. 2 positioning pin 10 installed is provided on the central axis of the measuring mounting seat 9 for installing the No. 2 positioning pin 10. After installation, the top of the No. 2 positioning pin 10 protrudes from the upper surface of the measuring mounting seat 9 and is configured to be inserted into the aperture to be measured at the bottom of the product.

[0039] In order to be able to quickly locate the installation of the measuring mounting seat 9, top hole connecting holes 11 are respectively opened on the diagonally opposite corners of the measuring mounting seat 9 located at the second positioning pin 10 for passing bolts to connect and install with the base 1 at the bottom. In addition, a top hole positioning hole 12 is also opened on the corresponding connecting line perpendicular to the pair of top hole connecting holes 11 and located at the diagonally opposite corner on the other side. The purpose is to achieve rapid positioning before bolt connection to ensure that the position of the measuring mounting seat 9 is accurate and not offset. Since corresponding through holes are provided on the base 1 corresponding to the top hole connecting hole 11 and the top hole positioning hole 12, the installation of the measuring mounting seat 9 and the base 1 is convenient.

[0040] It should be specifically explained that the No. 1 positioning pin 4 in the top aperture measurement unit is arranged above the top hole of the product. When no measurement is required, the No. 1 positioning pin 4 is moved to the side away from the product positioning seat 2. For this purpose, the top aperture measurement unit includes a No. 1 positioning pin 4 and a support unit for installing and clamping the No. 1 positioning pin 4. The bottom of the support unit is installed on the base 1, and the top is arranged higher than the product to be inspected.

[0041] On this basis, the supporting unit preferably adopts a supporting rod 13 whose bottom is installed on the base 1, and the top is extended with a connecting end with a reduced diameter upward, and then an elastic sleeve 14 is sleeved on the connecting end. One end of the rotating rod 15 is tightly sleeved on the elastic sleeve 14, and a No. 1 positioning pin 4 is installed on the other end. Since the elastic sleeve 14 adopts an external polygonal structure, the rotating rod 15 has a damping feeling when rotating, which can stabilize the No. 1 positioning pin at any angle, which is convenient for the installation of the product to be tested and can also improve the flexibility of the fixture.

[0042] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
