Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning tooling technology, and more specifically, to a positioning tooling for Z-axis reliability testing. Background Technology
[0002] Traditional Z-axis reliability testing fixtures require specialized jigs depending on the product or test item, making them unreliable. For example, in various reliability tests of common Ring components in the Z-axis, the different test standards and requirements necessitate the design and development of dedicated test jigs for each test item. Furthermore, significant structural differences between products in different projects mean that test jigs for one product cannot be directly applied to others, resulting in poor jig versatility and reusability. During multi-item testing, testers frequently need to disassemble, install, and replace jigs. This repetitive mechanical operation not only increases the workload of operators but also makes the entire testing process extremely cumbersome, ultimately artificially extending the testing cycle and reducing testing efficiency. Utility Model Content
[0003] In view of this, the present invention provides a positioning fixture for Z-axis reliability testing, which aims to solve the above-mentioned technical problems.
[0004] This utility model discloses a positioning fixture for Z-axis reliability testing, comprising a base and a cover plate. A bottom plate, a top plate, and a positioning pin are provided between the base and the cover plate. A connecting limiting structure is provided between the top plate and the cover plate. The base and the cover plate are detachably connected by a locking assembly. An clearance position is provided on the cover plate, and at least a portion of the test pull head extends through the clearance position into the product positioning space between the bottom plate and the top plate.

[0007] In some embodiments of this application, the product positioning space includes a product positioning slot one and a product positioning slot two, the product positioning slot one being disposed on the top plate and the product positioning slot two being disposed on the bottom plate.
[0008] In some embodiments of this application, at least a portion of the positioning pin passes through the product positioning space.
[0009] In some embodiments of this application, the connection limiting structure includes a connection groove and a stepped portion extending into the connection groove. The stepped portion is disposed on both sides of one of the top plate and the cover plate parallel to the Y-axis direction, and the connection groove is disposed on both sides of the remaining one of the top plate and the cover plate parallel to the Y-axis direction.
[0010] In some embodiments of this application, the connection limiting structure further includes a limiting member one and a limiting member two.

[0020] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.
[0021] Example 1, combined with Figures 1 to 3 As shown, this embodiment provides a positioning fixture for Z-axis reliability testing, including a base 1 and a cover plate 2. A bottom plate 3, a top plate 4, and a positioning pin 31 are provided between the base 1 and the cover plate 2. A connecting limiting structure is provided between the top plate 4 and the cover plate 2. The base 1 and the cover plate 2 are detachably connected by a locking assembly. An clearance position 21 is provided on the cover plate 2. At least a portion of the test pull head 5 passes through the clearance position 21 and extends into the product positioning space between the bottom plate 3 and the top plate 4.
[0022] Specifically, base 1 and cover plate 2 provide a universal and stable support structure. A locking assembly is installed between base 1 and cover plate 2. During testing, the locking assembly secures the bottom plate 3 and top plate 4 between base 1 and cover plate 2, ensuring the stability of the product within the product positioning space between bottom plate 3 and top plate 4 and guaranteeing efficient testing. For different test items or different products, only the locking assembly needs to be opened and the corresponding bottom plate 3 and top plate 4 replaced, avoiding the need for complete disassembly and assembly of the tooling, improving testing efficiency, and requiring only a few design changes to components, thus reducing production costs.
[0023] Combination Figure 5 , Figure 6 As shown, preferably, at least a portion of the product positioning space is disposed on the base plate 3, and the remaining portion of the product positioning space is disposed on the top plate 4.
[0024] Specifically, the product positioning space includes product positioning slot one 41 and product positioning slot two 32. Product positioning slot one 41 is located on the top plate 4, and product positioning slot two 32 is located on the bottom plate 3. The product positioning space is used to accommodate and fix the product, and the layered positioning slots facilitate disassembly and maintenance. During installation, the bottom plate 3 is first placed on the base 1, the product is placed in product positioning slot two 32 on the bottom plate 3, and then the top plate 4 and the cover plate 2 are integrated with the base 1 and locked in place by the locking assembly to ensure that the product remains stable during testing and will not be subject to unnecessary interference from external factors.
[0025] Preferably, at least a portion of the positioning pin 31 passes through the product positioning space.
[0026] Specifically, before the base plate 3 and top plate 4 are closed, at least part of the product is fitted onto the positioning pin 31, and then the base plate 3 and top plate 4 are closed and locked by the locking assembly to further fix the product and ensure stability during the test.
[0027] Combination Figures 1 to 3 as well as Figures 6 to 8 As shown, preferably, the connection limiting structure includes a connection groove 22 and a step portion 42 extending into the connection groove 22. The step portion 42 is disposed on both sides of one of the top plate 4 and the cover plate 2 parallel to the Y-axis direction, and the connection groove 22 is disposed on both sides of the remaining one of the top plate 4 and the cover plate 2 parallel to the Y-axis direction.
[0028] Specifically, since the top plate 4 and the cover plate 2 have mutually cooperating stepped portions 42 and connecting grooves 22 on both sides along the Y-axis, the top plate 4 can be embedded into the cover plate 2 along the Y-axis to form an integral structure during installation. At the same time, the mutually cooperating stepped portions 42 and connecting grooves 22 keep the top plate 4 and the cover plate 2 relatively fixed in the X-axis and Z-axis directions.
[0029] Preferably, the connecting limiting structure further includes a limiting member 23 and a limiting member 24. One end of the limiting member 23 passes through the cover plate 2 along the Z-axis and extends into the top plate 4. One end of the limiting member 24 passes through the cover plate 2 and / or the top plate 4 and extends into the limiting member 23.
[0030] Specifically, based on the mutually cooperating stepped portions 42 and connecting grooves 22 on both sides of the top plate 4 and the cover plate 2 along the Y-axis direction, a limiting member 23 extends through the cover plate 2 and into the top plate 4 along the Z-axis direction, preventing relative movement between the top plate 4 and the cover plate 2 along the Y-axis direction. Furthermore, a second limiting member 24 is cross-fixed with the first limiting member 23, keeping the first limiting member 23 fixed in the Z-axis direction, thus forming a relatively fixed whole between the cover plate 2 and the top plate 4.
[0031] Specifically, the X-axis, Y-axis, and Z-axis are all perpendicular to each other.
[0032] Understandably, the connection and limiting structure ensures that the top plate 4 and the cover plate 2 remain relatively fixed during testing, thereby guaranteeing the stability of the product within the product positioning space and improving testing accuracy. Furthermore, the connection and limiting structure is detachable, allowing for quick disassembly and replacement of the connection between the top plate 4 and the cover plate 2 during testing of different items or products, thus improving testing efficiency.
[0033] Preferably, the locking assembly includes a connector 11 and a slot 25, at least a portion of the connector 11 is rotatably disposed on one of the base plate 3 and the cover plate 2, the slot 25 is disposed on the other of the base plate 3 and the cover plate 2, and the remaining portion of the connector 11 is engaged in the slot 25.
[0034] Specifically, at least one set of locking components is provided on both sides of the base 1 and the cover plate 2 that are parallel to each other.
[0035] Understandably, after at least a portion of the connector 11 is inserted into the slot 25, the remaining portion is provided with a limiting part, which can fix the relative distance between the product positioning component and the support plate, thereby achieving locking.
[0036] Specifically, in this embodiment, the connector 11 can be a knurled screw.
[0037] Preferably, a second positioning pin 12 is provided between the base 1 and the cover plate 2, and a third positioning pin 13 is provided between the base 1 and the bottom plate 3.
[0038] Understandably, locating pin 12 is used to ensure precise alignment between base 1 and cover plate 2, and locating pin 13 is used to ensure precise alignment between base 1 and base plate 3, which helps to improve the stability and accuracy of the entire structure.
[0039] Combination Figure 4 As shown, preferably, the base 1 is provided with a receiving groove 14 for accommodating the base plate 3, which is used to further improve the positioning accuracy between the base 1 and the base plate 3.

Take the corresponding test pull head and lock or fix it to the corresponding test structure position on the product to start the test.
[0041] Example 2: Based on Example 1, this example sets the product positioning space on the top plate 4. The product positioning space includes a product placement slot on the side of the top plate 4 facing the bottom plate 3 and an end face of the bottom plate 3 adjacent to the top plate 4. During installation, the product is first placed in the product placement slot, and simultaneously, the product is attracted to the other side of the top plate 4 where the product placement slot is located using a magnet. Then, the top plate 4 and the cover plate 2 are completely fitted together with the bottom plate 3 and the base 1.
[0042] This embodiment provides a specific operating method for a positioning fixture used for Z-axis reliability testing, as follows: S21. Fix the base 1 onto the platform of the tensile testing equipment; S22. Based on S21, place a magnet at the corresponding position of the clearance position 21 of the cover plate 2 and the product placement slot 1, rotate the cover plate 2 so that the bottom is facing upward, put the product into the product placement slot 1, and fix the product by adsorption of the magnet. S23. Place the base plate 3 on the base 1 according to the positioning pin 3 13 and the receiving groove 14; S24.
