Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a testing tooling. Background Technology

[0002] In the process of inspecting the finished dimensions of precision support rods, it is usually necessary to place and position a large number of precision support rods. In the existing technology, the placement of precision support rods is generally done manually. However, manual placement is inefficient and it is difficult to ensure the neatness and positioning accuracy of the precision support rods. Manual placement is also prone to damaging the materials, increasing production and inspection costs.

[0003] Currently, although there are some specialized tooling tools available for placing and inspecting precision support rods, these tooling tools are usually only applicable to precision support rods of specific specifications, have poor versatility and insufficient precision, and there is a problem that it is difficult to align and position the tail ends of multiple precision support rods.

[0004] Chinese patent CN215749107U, published on February 8, 2022, discloses a placement device for photovoltaic module testing fixtures. The device includes a movable platform with a support for placing the fixtures. The support has multiple grooves, with any two adjacent grooves spaced apart, and any groove is used to limit the placement of the fixtures. While this device can stably place multiple fixtures on one device, the groove dimensions are fixed, making it unsuitable for precision support rods of different specifications. Furthermore, the groove dimensions are relatively large, making it impossible to neatly place and position hundreds of precision pins. In addition, for the dimensional inspection of precision support rods, the horizontal alignment of their placement significantly affects the accuracy of μm dimension detection. Therefore, this device cannot yet meet the needs of high-precision, high-efficiency batch testing of precision support rods.

[0005] It is evident that providing a universal, high-precision placement fixture capable of efficiently and neatly placing rods of different specifications and aligning the ends of multiple rods for use in loading / unloading of rods or in dimensional inspection of precision support rods remains a pressing technical problem to be solved in this field. Utility Model Content

[0006] To address the technical problem of how to provide a universal, high-precision inspection fixture for efficiently and neatly placing rod-shaped materials and achieving flush tail ends, this utility model provides an inspection fixture, including a support component and auxiliary components;

[0007] The support member includes a support plate and support side plates located on both sides of the support plate along its length.

[0008] The length of the supporting side plate is greater than the width of the supporting plate;

[0009] The auxiliary component includes an auxiliary plate and auxiliary side plates located on both sides of the auxiliary plate along its length.

[0010] The length of the auxiliary plate is equal to the length of the support plate;

[0011] The auxiliary component is located on the support side plate and can move along the support side plate in the width direction of the support plate;

[0012] The upper surface of the support plate is provided with a plurality of equally spaced grooves, the grooves being perpendicular to the length direction of the auxiliary component and penetrating the side of the support plate near the auxiliary component;

[0013] The auxiliary plate protrudes towards the support plate, and the height of the protruding part is greater than or equal to the vertical distance from the upper surface of the support side plate to the bottom of the groove.

[0014] In one embodiment, the supporting side plate is relatively higher than the supporting plate.

[0015] In one embodiment, the groove is an arc-shaped groove.

[0016] In one embodiment, the groove is a V-shaped groove with an included angle of 30° to 60° between the two side walls.

[0017] In one embodiment, the bottom of the trench is a curved surface with a radius of curvature R ≤ 0.075 mm.

[0018] Furthermore, the groove opening width is 0.06 mm ~ 1 mm, and the groove depth is 0.09 mm ~ 1 mm.

[0019] In one embodiment, the distance between two adjacent grooves is 1.5 mm to 3.5 mm.

[0020] In one embodiment, the auxiliary component further includes a tooling plate disposed on the opposite side of the auxiliary plate; the tooling plate protrudes relative to the auxiliary side plate, and the height of the protruding portion is less than or equal to the vertical distance from the upper surface of the support side plate to the upper surface of the support plate.

[0021] Furthermore, the tooling plate is a flat plate structure or a grooved plate structure; wherein, when the tooling plate is a grooved plate structure, the groove shape is V-shaped or arc-shaped, the groove width is 0.1 mm ~ 1 mm, and the included angle between the two side walls of the V-shaped groove is 30° ~ 60°.

[0022] In one embodiment, the support side plate is provided with a limiting groove, and the auxiliary side plate is provided with a limiting block. The limiting block can be wedged into the limiting groove and move along the width direction of the support plate.

[0023] In this invention, the angular tolerance is ±1° and the dimensional tolerance is ±0.005 mm.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The testing fixture provided by this utility model solves the problem of manual sampling and placement of each rod by opening several equally spaced precision grooves on the surface of the support plate. This is done to place precision support rods and achieve positioning and limiting, thus solving the problem that existing rod inspection and placement fixtures require manual sampling and placement of each rod. Furthermore, with the use of auxiliary parts, it enables rapid flushing of the tail ends of precision support rods, greatly improving the efficiency of neat material placement. In addition, the use of the fixture plate can also enable rapid placement of precision support rods, and the use of limiting blocks and limiting grooves can further ensure operational accuracy during rapid material placement and tail end flushing.

[0026] In addition, the V-groove design allows grooves of the same size to accommodate the placement of rods and materials of various sizes and specifications, resulting in good tooling versatility and reducing material waste.

[0027] In summary, the testing fixture provided by this utility model is suitable for the rapid positioning and placement of precision support rods of various specifications and in large quantities. It effectively limits the material at equal intervals, ensuring that the material tail ends are neatly oriented. It overcomes the risks and defects of manual placement, such as being time-consuming and labor-intensive, having large positioning errors, inconsistent orientations, inconsistent spacing, and being prone to material damage. When used for batch automatic testing of precision support rods, the fixture significantly improves efficiency. Furthermore, because the material is accurately positioned and at equal intervals after the fixture is installed, the image of the material captured by the testing equipment is clear, the testing continuity is good, and the testing efficiency is high.

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.

[0044] Example 1

[0045] This embodiment provides a testing fixture for placing precision support rods and similar materials, which, in conjunction with automated testing equipment, completes efficient dimensional inspection. (See reference...) Figure 1 As shown, it includes a support member 100 and an auxiliary member 200;

[0046] The support member 100 includes a support plate 110 and support side plates 120 located on both sides of the support plate 110 along its length.

[0047] It should be noted that, in this utility model, as shown in... Figure 1 The longer side of the support plate 110 shown is its length direction, and the shorter side is its width direction. The length direction of the support side plate 120 corresponds to the width direction of the support plate 110.

[0048] See Figure 2 As shown, the length of the support side plate 120 is greater than the width of the support plate 110, and both ends of the support side plate 120 protrude from the support plate 110.

[0049] See Figure 3 As shown, the auxiliary component 200 includes an auxiliary plate 210 and auxiliary side plates 220 located on both sides of the auxiliary plate 210 in the length direction;

[0050] It should be noted that in this utility model, the length and width of the auxiliary plate 210 are consistent with those of the support plate 110, and the length and width of the auxiliary side plate 220 are consistent with those of the support side plate 120.

[0051] The length of the auxiliary plate 210 is equal to the length of the support plate 110;

[0052] The auxiliary component 200 is located on the support side plate 120 and can move along the support side plate 120 in the width direction of the support plate 110;

[0053] See Figure 1 , Figure 4 As shown, the upper surface of the support plate 110 is provided with a plurality of equally spaced grooves 111. The grooves 111 are perpendicular to the length direction of the auxiliary component 200 and penetrate the side of the support plate 110 near the auxiliary component 200.

[0054] See Figure 5 As shown, the auxiliary plate 210 protrudes towards the support plate 110, and the height of the protruding part is greater than or equal to the vertical distance from the upper surface of the support side plate 120 to the bottom of the groove 111.

[0055] In practical use, the precision support rod material is placed into the groove 111, and the auxiliary component 200 is pushed to slide along the support side plate 120 toward the rear end of the support plate 110. The auxiliary plate 210 will contact the end of the material and continue to push it until it abuts the front end face of the support plate 110.

[0056] It should be noted that, in this utility model, the term "front end" refers to, for example, Figure 1 In the orientation and device state shown, the support plate 110 is located at one end close to the auxiliary component 200, and the "rear end" refers to the end away from the auxiliary component 200 along the width direction of the support plate 110.

[0057] See Figure 4 As shown, the supporting side plate 120 is relatively higher than the supporting plate 110;

[0058] In this embodiment, preferably, the thickness of the supporting side plate 120 is 10 mm, the thickness of the supporting plate 110 is 9.5 mm, and the lower surfaces of the supporting side plate 120 and the supporting plate 110 are flush.

[0059] In this embodiment, preferably, the auxiliary side plate 220 has a thickness of 10 mm, the auxiliary plate 210 has a thickness of 12 mm, and the height of the portion of the auxiliary plate 210 protruding from the auxiliary side plate 220 is 2 mm.

[0060] In this embodiment, preferably, the groove 111 is a V-shaped groove with an included angle of 60° between the two side walls;

[0061] In this embodiment, preferably, the groove 111 has a groove opening width of 0.3 mm, a groove depth of 0.26 mm, and a groove bottom curvature radius R of 0.075 mm;

[0062] The vertical distance from the upper surface of the support side plate 120 to the bottom of the groove 111 is 0.76 mm, which is less than the height of the protruding part of the auxiliary plate 210 relative to the auxiliary side plate 220 by 2 mm.

[0063] In practical use, when the auxiliary component 200 is pushed, the auxiliary side plate 220 slides along the support side plate 120, and the auxiliary plate 210 is embedded between the two support side plates 120 and protrudes relative to the auxiliary side plate 220. The horizontal height of the lower surface of the protruding part is lower than the horizontal height of the bottom of the groove 111. Therefore, when the protruding part successively abuts the end of the precision support rod material, it pushes the material to slide towards the rear end of the support plate 110 in the groove 111. When it reaches the front end of the support plate 110, it will be abutted and will no longer move, thereby achieving the alignment of the tail ends of multiple precision support rod materials.

[0064] In this embodiment, preferably, the distance between two adjacent grooves 111 is 2.5 mm; the distance between the first and last grooves 111 and the supporting sidewall 120 is 2 mm.

[0065] In practical use, the 2.5 mm slot spacing enables the detection equipment to capture material images more clearly, improving detection and analysis efficiency and accuracy.

[0066] It should also be noted that, in this embodiment, the size design of the groove 111 is suitable for precision support rod materials with a diameter of 0.1 mm to 1 mm. Those skilled in the art can design the groove size according to the specific product size and the requirements of the detection accuracy. If necessary, the size of the support and auxiliary parts can also be adapted and designed at the same time, but it is still within the protection scope of this utility model.

[0067] Example 2

[0068] This embodiment provides a testing fixture that can be used to quickly place precision support rods or similar materials.

[0069] Based on Example 1, see [link / reference] Figure 6 As shown, the auxiliary component 200 also includes a tooling plate 230 with a flat plate structure, which is disposed on the opposite side of the auxiliary plate 210;

[0070] The tooling plate 230 protrudes relative to the auxiliary side plate 220, and the height difference between the tooling plate 230 and the auxiliary side plate 220 is 0.5 mm, which is equal to the vertical distance of 0.5 mm between the upper surface of the support side plate 120 and the upper surface of the support plate 110.

[0071] In practical use, a certain number of precision support rod materials are laid on the surface of the support plate 110. The auxiliary component 200 is located at the front end of the support component 100, and the tooling plate 230 is facing downwards. The tooling plate 230 is pushed to slide towards the rear end of the support plate 110. The protruding part of the tooling plate 230 relative to the auxiliary side plate 220 will abut against the tail end of the material that has not fallen into the groove 111, and under the pushing action of the tooling plate 230, it will be pushed out of the surface area of ​​the support plate 110, thereby realizing the efficient and rapid placement of precision support rod materials. Furthermore, the auxiliary component 200 is flipped over, and the auxiliary plate 210 is used to achieve the flush treatment of the tail end of the material, that is, the flush and rapid placement of multiple precision support rod materials is completed, which meets the requirements of automated testing equipment to complete efficient dimensional testing.

[0072] It should be noted that, based on the size design of the support plate, auxiliary plate, tooling plate and groove in embodiments 1 and 2 of this utility model, this embodiment is applicable to precision support rod materials with a diameter of 0.1 mm. Those skilled in the art can adjust the groove size according to the size of the product to be inspected, and further make adaptive adjustments and designs to the dimensions of the support plate, support side plate, auxiliary plate and auxiliary side plate thickness according to the size design principles in this utility model, but it is still within the protection scope of this utility model.

[0073] Example 3

[0074] This embodiment provides a testing fixture that can be used to quickly place precision support rods or similar materials.

[0075] Based on Example 1, see [link / reference] Figure 7 As shown, the auxiliary component 200 also includes a tooling plate 230 with a grooved plate structure, which is disposed on the opposite side of the auxiliary plate 210;

[0076] The tooling plate 230 protrudes relative to the auxiliary side plate 220, and the height difference between the tooling plate 230 and the auxiliary side plate 220 is 0.5 mm, which is equal to the vertical distance of 0.5 mm from the upper surface of the support side plate 120 to the upper surface of the support plate 110.

[0077] The groove plate structure has a V-shaped groove, a 60° included angle between the two side walls, a groove width of 0.3 mm, a groove spacing of 2.5 mm, and a vertical distance of 2 mm between the first and last grooves and the auxiliary side wall 220.

[0078] In practical use, precision support rods that do not fall into the groove 111 will be pushed away from the surface of the support plate 110 by the tooling plate 230, while precision support rods that have completely fallen into or partially or more of the groove 111 can be retained on the support plate 110 through the V-shaped groove of the tooling plate 230.

[0079] It should be noted that, based on the size design of the support plate, auxiliary plate, tooling plate and groove in embodiments 1 and 3 of this utility model, this embodiment is applicable to precision support rod materials with a diameter of 0.1 mm to 0.15 mm. Those skilled in the art can adjust the groove size according to the size of the product to be inspected, and further make adaptive adjustments and designs to the dimensions of the support plate, support side plate, auxiliary plate and auxiliary side plate thickness according to the size design principles in this utility model, but it is still within the protection scope of this utility model.

[0080] Example 4

[0081] This embodiment provides a testing fixture that can be used for the precise and rapid placement of precision support rods and similar materials.

[0082] Based on Example 3, see [link to Example 3] Figure 8 , 9 The supporting side plate 120 is provided with a limiting groove 121, see reference. Figure 10 , 11 The auxiliary side plate 220 is provided with a limiting block 221, which can wedge and slide with the limiting groove 121;

[0083] The combined use of the limiting block 221 and the limiting groove 121 can improve the tooling accuracy of multiple precision support rods in rapid tooling.

[0084] In practical use, the limiting block 221 on the tooling plate 230 side is aligned with the limiting groove 121 to complete the assembly of the quick tooling mode of the detection tooling. The limiting block 221 is wedge-fitted and slids in the limiting groove 121 to complete the quick positioning and placement of multiple precision support rods. Then, the limiting block 221 on the auxiliary plate 210 side is aligned with the limiting groove 121 and wedge-fitted and slids to complete the flushing of the tail ends of multiple precision support rods.

[0085] It should be noted that the limiting block 221 can be any one of the following: square, cylindrical, hemispherical, 3 / 4 spherical, and spherical. The limiting groove 121 can also be adjusted accordingly. However, the changes, selections, and adjustments of the above design do not cause the essence of the corresponding technical solution to deviate from the scope of the technical solution of this utility model.

[0086] Although this document frequently uses terms such as testing fixture, support component, auxiliary component, support plate, support side plate, groove, auxiliary plate, auxiliary side plate, fixture plate, limiting block, limiting groove, arc groove, V-groove, flat plate structure, groove plate structure, precision support rod material, and rod material, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this utility model; interpreting them as any additional limitation would contradict the spirit of this utility model.

[0087] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
