Description

Technical Field

[0001] This utility model relates to the technical field of large tooling processing equipment, and in particular to a large tooling positioning structure. Background Technology

[0002] In the aerospace field, the use of large tooling is common. When using overhead cranes to hoist tooling into machine tools and align it with the positioning base, the outer wall of the tooling can obstruct the operator's view, making it difficult to observe the mating positions of the positioning pins and holes. This hinders the installation of large tooling and positioning devices, resulting in lengthy installation times and a high risk of damaging the tooling base. Therefore, there is an urgent need for a large tooling positioning structure that allows the operator to easily observe the mating positions of the positioning pins and holes when hoisting the tooling into the machine tool and aligning it with the positioning base, reducing hoisting difficulty and preventing damage to the tooling base. Utility Model Content

[0003] In view of the above-mentioned problems of the prior art, this application provides a large tooling positioning structure, which allows the operator to easily observe the mating position of the positioning pin and the positioning hole when the tooling is hoisted into the machine tool and docked with the positioning base, thereby reducing the difficulty of hoisting and avoiding damage to the tooling base.

[0004] To achieve the above objectives, this application provides a large tooling positioning structure, comprising: a tooling, wherein a positioning pin is vertically disposed at the bottom of the tooling; and a positioning base, wherein a positioning hole is disposed on the upper surface of the positioning base at the position corresponding to the positioning pin, and the positioning hole is adapted to the positioning pin.

[0005] By adopting the above structure, placing the locating pin at the bottom of the fixture and the locating hole on the upper surface of the locating base, the connection point between the locating pin and the locating hole can be moved from the bottom of the fixture to the upper surface of the locating base. This allows the operator to shift their line of sight from looking upwards to looking downwards, preventing the outer wall of the fixture from obstructing their view. This facilitates observation of the mating position of the locating pin and the locating hole, reduces lifting difficulty, and avoids damage to the fixture base.

[0006] In some embodiments, multiple positioning pins are provided corresponding to the positioning holes.

[0007] By adopting the above structure and setting multiple positioning pins and positioning holes, large tooling can be positioned at multiple positions, thereby improving the firmness and stability of positioning large tooling.

[0008] In some embodiments, the positioning base is a cuboid component, and the positioning holes are arranged in pairs, with the two positioning holes in a pair located at opposite corners on the upper surface of the positioning base.

[0009] By adopting the above structure, the two locating pins can be connected to the locating holes at the farthest position on the upper surface of the locating base, thereby improving the firmness and stability of positioning large tooling.

[0010] In some embodiments, the lower edge of the locating pin is chamfered.

[0011] By employing the above structure, a chamfer is provided at the lower edge of the locating pin. This chamfer guides the locating pin as it is inserted into the locating hole, facilitating insertion from both sides. This reduces the difficulty of hoisting and prevents damage to the tooling base.

[0012] In some embodiments, the positioning pin is cylindrical, the positioning hole is circular, and the diameter of the positioning pin is adapted to the diameter of the positioning hole.

[0013] The above structure allows for easy insertion of the positioning pin into the positioning hole, thereby reducing the difficulty of hoisting and preventing damage to the tooling base.

[0014] In some embodiments, the length of the locating pin is less than or equal to the depth of the locating hole.

[0015] By adopting the above structure, the length of the positioning pin is less than or equal to the depth of the positioning hole, so that the positioning pin can be fully inserted into the positioning hole, allowing the bottom of the large tooling to fit against the upper surface of the positioning base, thereby improving the stability of the connection between the large tooling and the positioning base.

[0016] In some embodiments, the lower surface of the positioning base is adapted to the bottom surface of the tooling.

[0017] By adopting the above structure, the lower surface of the positioning base is adapted to the bottom surface of the tooling, so that the bottom of the large tooling can be completely fitted with the upper surface of the positioning base, thereby improving the stability of the connection between the large tooling and the positioning base.

[0018] These and other aspects of this invention will become more readily apparent in the following description of several embodiments. Attached Figure Description

Furthermore, in one or more embodiments, the particular features, structures, or characteristics can be combined in any suitable manner, as will be apparent to those skilled in the art from this disclosure.

[0025] The following is a detailed description of the specific structure 10 of the large tooling positioning structure 10 in this application, with reference to the accompanying drawings.

[0026] This application provides a large tooling positioning structure 10, including a tooling 100 and a positioning base 200. A positioning pin 110 is vertically disposed at the bottom of the tooling 100. The positioning pin 110 can be fixedly disposed at the bottom of the tooling 100 or disposed at the bottom of the tooling 100 via a detachable connection; there is no limitation on this. A positioning hole 210 is provided on the upper surface of the positioning base 200 at the corresponding position of the positioning pin 110, and the positioning hole 210 is adapted to the positioning pin 110. Therefore, by placing the positioning pin 110 at the bottom of the tooling 100 and the positioning hole 210 on the upper surface of the positioning base 200, the connection position between the positioning pin 110 and the positioning hole 210 can be transferred from the bottom of the tooling 100 to the upper surface of the positioning base 200. This allows the operator to shift their line of sight from looking upwards to looking downwards, thus preventing the outer wall of the tooling 100 from obstructing the operator's view. It also makes it easier for the operator to observe the mating position of the positioning pin 110 and the positioning hole 210, reducing the difficulty of hoisting and preventing damage to the base of the tooling 100.

[0027] In some embodiments, multiple positioning pins 110 and positioning holes 210 are provided correspondingly. Thus, by providing multiple positioning pins 110 and positioning holes 210, the large tooling 100 can be positioned at multiple positions, thereby improving the firmness and stability of positioning the large tooling 100.

[0028] In some embodiments, the positioning base 200 is a cuboid component, with positioning holes 210 arranged in pairs, each pair of positioning holes 210 positioned diagonally on the upper surface of the positioning base 200. This allows the two positioning pins 110 to connect with the positioning holes 210 at the furthest point on the upper surface of the positioning base 200, thereby improving the firmness and stability of positioning the large tooling 100.

[0029] In some embodiments, a chamfer is provided at the lower edge of the positioning pin 110. Therefore, by providing a chamfer at the lower edge of the positioning pin 110, the positioning pin 110 can be guided by the chamfer when inserted into the positioning hole 210, facilitating insertion from two directions. This reduces the difficulty of hoisting and avoids damage to the fixture 100 base.

[0030] In some embodiments, the positioning pin 110 is cylindrical, and the positioning hole 210 is circular, with the diameter of the positioning pin 110 matching that of the positioning hole 210. This allows the positioning pin 110 to be easily inserted into the positioning hole 210, thereby reducing the difficulty of hoisting and preventing damage to the fixture 100 base.

[0031] In some embodiments, the length of the positioning pin 110 is less than or equal to the depth of the positioning hole 210. Therefore, by making the length of the positioning pin 110 less than or equal to the depth of the positioning hole 210, the positioning pin 110 can be fully inserted into the positioning hole 210, so that the bottom of the large tooling 100 fits against the upper surface of the positioning base 200, thereby improving the stability of the connection between the large tooling 100 and the positioning base 200.

[0032] In some embodiments, the lower surface of the positioning base 200 is adapted to the bottom surface of the tooling 100. Thus, by adapting the lower surface of the positioning base 200 to the bottom surface of the tooling 100, the bottom of the large tooling 100 can be completely fitted with the upper surface of the positioning base 200, thereby improving the stability of the connection between the large tooling 100 and the positioning base 200.

[0033] The above description provides an exemplary description of possible embodiments of the large tooling positioning structure 10. Below, with reference to the accompanying drawings, a detailed description of the specific structure 10 of the large tooling positioning structure 10 will be given in a particular embodiment.

[0034] Figure 1 This is a three-dimensional structural diagram of the large tooling positioning structure 10 in this application. As shown in the figure, the large tooling positioning structure 10 in this application includes a tooling 100 and a positioning base 200. The positioning base 200 can be detachably mounted on a machine tool, and the tooling 100 can be hoisted onto the positioning base 200 by means of an overhead crane or other equipment, and can be detachably connected to the positioning base 200 shell, thereby facilitating the machine tool to process the tooling 100.

[0035] like Figure 1 As shown, the positioning base 200 is a cuboid component. The upper surface of the positioning base 200 is provided with two circular positioning holes 210, which are located at a set of diagonal positions on the upper surface of the positioning base 200.

[0036] like Figure 1 As shown, the bottom of the fixture 100 is flat, and a positioning pin 110 is provided at each of the two corresponding positions of the positioning holes 210 on the bottom of the fixture 100. The positioning pin 110 is cylindrical, and the diameter of the positioning pin 110 is adapted to the diameter of the positioning hole 210. The edge of the positioning pin 110 away from the fixture 100 is chamfered to facilitate the insertion of the positioning pin 110 into the positioning hole 210. The length of the positioning pin 110 is less than the depth of the positioning hole 210 so that the positioning pin 110 can be fully inserted into the positioning hole 210, so that the bottom surface of the fixture 100 fits against the upper surface of the positioning base 200.

Those skilled in the art will understand that this utility model is not limited to the specific embodiments described herein, and various obvious changes, readjustments, and substitutions can be made without departing from the protection scope of this utility model.
