Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary devices for testing equipment, and in particular to a multi-directional adjustment adapter plate fixing and protective fixture. Background Technology

[0002] Several technical problems exist in the current testing process that urgently need to be addressed. On the one hand, when the test adapter board is directly inserted into the test equipment port, there are no protective or securing measures. In actual operation, even slight carelessness can easily damage the test equipment port and the adapter board, increasing equipment maintenance costs and affecting the continuity of testing. On the other hand, operators need to visually align the test adapter board during testing, which is extremely inefficient. Prolonged repetitive operations significantly increase the operator's workload and are also detrimental to large-scale production testing. Utility Model Content

[0003] This utility model aims to at least partially solve one of the problems in related technologies. Therefore, one of the objectives of this utility model is to provide a multi-directional adjustable adapter plate fixing and protective fixture, which can be used to achieve compatibility with different models of testing equipment, thereby fixing and protecting the test adapter plate.

[0004] A multi-directional adjustable adapter plate fixing and protective fixture, the multi-directional adjustable adapter plate fixing and protective fixture comprising:

[0005] A first adjustment plate has a first adjustment hole extending vertically, and the first adjustment plate is connected to the test equipment through the first adjustment hole.

[0006] The second adjustment plate has a second adjustment hole that extends horizontally. The second adjustment plate is connected to the first adjustment plate through the second adjustment hole, and the horizontal position of the second adjustment plate can be adjusted.

[0007] The third adjustment plate has a third adjustment hole that extends horizontally and is perpendicular to the extension direction of the second adjustment hole. The third adjustment plate is connected to the second adjustment plate through the third adjustment hole, and the horizontal position of the third adjustment plate can be adjusted. The test adapter plate is installed on the third adjustment plate.

[0008] Furthermore, the first adjustment hole, the second adjustment hole, and the third adjustment hole are all oblong holes.

[0009] Furthermore, there are multiple first adjustment holes, and the multiple first adjustment holes are spaced apart along the extension direction of the first adjustment plate;

[0010] And / or, the number of the second adjustment holes is multiple, and the multiple second adjustment holes are spaced apart along the extension direction of the second adjustment plate;

[0011] The number of the third adjustment holes is multiple, and the multiple third adjustment holes are spaced apart along the extension direction of the third adjustment plate.

[0012] Furthermore, the second adjustment plate is also provided with an auxiliary support member, which is foldably connected to the side surface of the second adjustment plate near the bottom, and the auxiliary support member is opened to abut against the test equipment.

[0013] Furthermore, the first adjustment hole is a double-layer adjustment hole, which includes a lower adjustment hole and an upper adjustment hole stacked together, wherein the diameter of the upper adjustment hole is larger than that of the lower adjustment hole.

[0014] Furthermore, the wall of the first adjustment hole is provided with an elastic liner, the elastic liner being made of rubber or an elastic metal material.

[0015] Furthermore, the third adjustment plate has a mounting groove, the cross-sectional shape of which is adapted to the cross-sectional shape of the test adapter plate, and the test adapter plate is installed in the mounting groove.

[0016] Furthermore, a positioning protrusion is provided in the mounting groove, which is adapted to the groove of the test adapter plate.

[0017] Furthermore, the wall of the mounting groove is connected to a buffer layer.

[0018] Furthermore, the sidewall of the mounting groove has an opening corresponding to the end of the test adapter plate, and the edge of the opening is chamfered.

[0019] The technical solutions provided in this application have the following advantages compared with the prior art:

[0020] In this application, after the fixture is fixed on the testing equipment, the multi-directional adjustment structure composed of the first adjustment plate, the second adjustment plate and the third adjustment plate can be adjusted in different directions such as up and down, left and right, and front and back, so as to meet the compatibility with different models of testing equipment and achieve the purpose of fixing and protecting the test adapter plate.

[0021] The robust structure formed by the combination of the first, second, and third adjustment plates securely fixes the test adapter plate in a specific position. Once the test adapter plate is mounted on the third adjustment plate and secured with fastening bolts, it is stably restrained and will not shake or shift due to external impacts or improper operation. This effectively protects the test adapter plate from potential damage caused by hard friction or collisions with the test equipment ports during testing.

[0022] Furthermore, during the initial preparation phase, operators can adjust the fixture and test adapter plate to accurately align with the test equipment port by using the first adjustment hole and bolt on the first adjustment plate, moving the second adjustment plate on the first adjustment plate, and moving the third adjustment plate on the second adjustment plate, depending on the model of the test equipment. Once adjusted and fixed, for each subsequent test, simply insert the fixture with the test adapter plate into the test equipment port according to the fixed position and direction; no visual alignment by the operator is required, truly achieving blind insertion and improving production efficiency.

Therefore, they should not be construed as limitations on this invention.

[0035] like Figures 1 to 5 As shown, the multi-directional adjustment adapter plate fixing and protective fixture 1 provided in this application includes:

[0036] The first adjustment plate 10 has a first adjustment hole 11, which extends vertically, and the first adjustment plate 10 is connected to the test equipment through the first adjustment hole 11.

[0037] The second adjustment plate 20 has a second adjustment hole 21, which extends horizontally. The second adjustment plate 20 is connected to the first adjustment plate 10 through the second adjustment hole 21, and the horizontal position of the second adjustment plate 20 can be adjusted.

[0038] The third adjustment plate 30 has a third adjustment hole 31, which extends horizontally and is perpendicular to the extension direction of the second adjustment hole 21. The third adjustment plate 30 is connected to the second adjustment plate 20 through the third adjustment hole 31, and the horizontal position of the third adjustment plate 30 can be adjusted. The test adapter plate 2 is installed on the third adjustment plate 30.

[0039] The first adjustment plate 10 is connected to the testing equipment through the first adjustment hole 11 extending vertically, enabling vertical adjustment; the second adjustment plate 20 is connected to the first adjustment plate 10 through the second adjustment hole 21 extending horizontally, allowing it to move left and right; the third adjustment plate 30 is connected to the second adjustment plate 20 through the third adjustment hole 31 perpendicular to the second adjustment hole 21, enabling it to be adjusted forward and backward; the test adapter plate 2 is mounted on the third adjustment plate 30, thereby achieving multi-directional adjustment and fixing the adapter plate to the testing equipment.

[0040] The specific usage steps are as follows:

[0041] The first adjustment plate 10 is fixed to a suitable position on the test equipment with bolts to ensure that the first adjustment plate 10 is vertical and stable.

[0042] Based on the specific model of the testing equipment and the position of the testing adapter plate 2, the height of the first adjustment plate 10 is adjusted by adjusting the position of the positioning pin in the first adjustment hole 11, thereby achieving preliminary adjustment in the vertical direction.

[0043] Install the second adjusting plate 20 onto the first adjusting plate 10 through the second adjusting hole 21. Adjust the position of the second adjusting plate 20 on the first adjusting plate 10 as needed, and then tighten the fastening bolts to fix it.

[0044] Install the third adjustment plate 30 onto the second adjustment plate 20 through the third adjustment hole 31, install the test adapter plate 2 onto the third adjustment plate 30, adjust the position of the third adjustment plate 30 according to the position of the test equipment port, and finally tighten the fastening bolts to fix it.

[0045] After completing the above installation and adjustments, the test adapter board 2 can be accurately connected to the port of the test equipment using the fixture to carry out the test.

[0046] Optionally, the first adjustment plate 10 is made of high-strength aluminum alloy, which is lightweight and high-strength, and can reduce the overall weight of the fixture while ensuring structural stability.

[0047] Optionally, the part of the first adjustment plate 10 that connects to the testing equipment is configured as a dovetail groove structure, and a dovetail block is correspondingly provided on the testing equipment. The two are fastened together by bolts passing through the first adjustment hole 11. This connection method is not only easy to install, but also enhances the stability of the connection and prevents the first adjustment plate 10 from shifting during the test.

[0048] Optionally, the second adjustment plate 20 is made of stainless steel and has a rust-proof surface treatment to adapt to complex testing environments.

[0049] Optionally, a T-shaped slider is provided on the side where the second adjustment plate 20 is connected to the first adjustment plate 10. It cooperates with the T-shaped slide groove on the first adjustment plate 10. The position of the second adjustment plate 20 in the T-shaped slide groove is adjusted by bolts through the second adjustment hole 21 to achieve more precise horizontal adjustment.

[0050] Optionally, the third adjustment plate 30 is made of carbon fiber composite material, which has the advantages of high strength, high rigidity and low weight, and can effectively reduce the adjustment error caused by its own weight.

[0051] Optionally, the third adjusting plate 30 is connected to the second adjusting plate 20 via a ball bearing guide. The ball bearing guide reduces the coefficient of friction, making the horizontal movement of the third adjusting plate 30 smoother, and together with the third adjusting hole 31, it achieves high-precision front and rear position adjustment.

[0052] Furthermore, the first adjustment hole 11, the second adjustment hole 21 and the third adjustment hole 31 are all oblong holes.

[0053] Specifically, the first, second, and third adjustment holes are all designed as waist-shaped holes. The elongated structure of the waist-shaped holes allows the connecting parts to have room to move in the extension direction of the holes, making it convenient to adjust their positions. Moreover, this shape is simple to process, low in cost, and can meet the needs of multi-directional adjustment.

[0054] Optionally, anti-slip grooves are provided on the walls of the first, second, and third adjustment holes. The anti-slip grooves adopt a fine serrated design. When the bolts are tightened, the anti-slip grooves can increase the friction between the bolts and the adjustment holes, preventing the bolts from loosening due to vibration or external force during the test, and ensuring that the position of the adjustment plate is fixed.

[0055] Furthermore, there are multiple first adjustment holes 11, and the multiple first adjustment holes 11 are spaced apart along the extending direction of the first adjustment plate 10;

[0056] And / or, the number of second adjustment holes 21 is multiple, and the multiple second adjustment holes 21 are spaced apart along the extension direction of the second adjustment plate 20;

[0057] There are multiple third adjustment holes 31, which are spaced apart along the extension direction of the third adjustment plate 30.

[0058] In this embodiment, multiple first adjustment holes 11 are spaced apart along the extension direction of the first adjustment plate 10, providing more vertical adjustment points; similarly, multiple second and third adjustment holes are distributed along the extension direction of their respective adjustment plates, allowing for more precise horizontal (left and right, front and back) adjustments to meet the installation requirements of different testing equipment and adapter plates.

[0059] Optionally, in addition to being spaced apart along the extension direction of the adjustment plate, some adjustment holes are also added on the diagonal of the adjustment plate to form a cross-distributed layout of adjustment holes. This layout allows the second adjustment plate 20 and the third adjustment plate 30 to be adjusted more flexibly in the horizontal direction, and can meet the complex port position requirements of test equipment.

[0060] Furthermore, the second adjustment plate 20 is also provided with an auxiliary support member, which is foldably connected to the side surface of the second adjustment plate 20 near the bottom, and the auxiliary support member is opened to support the test equipment.

[0061] Specifically, foldable or retractable auxiliary supports are provided at the edges or specific locations of the first adjustment plate 10, the second adjustment plate 20, and the third adjustment plate 30. When the adjustment plates need to withstand large external forces (such as the heavy test adapter plate 2) or are used in complex environments, the auxiliary supports can be unfolded or extended to enhance the stability of the adjustment plates and prevent deformation due to uneven force, which would affect the fixing and adjustment accuracy of the test adapter plate 2. For example, a retractable metal support foot is installed on the side of the second adjustment plate 20 closest to the test equipment. When the adapter plate is heavy, the support foot extends out to contact the surface of the test equipment, sharing part of the weight of the adapter plate.

[0062] Optionally, the auxiliary support component adopts a telescopic hydraulic rod structure. One end of the hydraulic rod is connected to the surface of the second adjusting plate 20 near the bottom via a hinge, and the other end is equipped with a rubber suction cup. In use, the hydraulic rod is extended, allowing the rubber suction cup to adhere to the surface of the testing equipment. Stable support force is provided by the hydraulic oil pressure inside the hydraulic rod. The surface of the rubber suction cup is designed with anti-slip textures to enhance adhesion and prevent the auxiliary support component from sliding on the surface of the testing equipment. Simultaneously, a pressure adjustment knob is provided on the hydraulic rod, allowing adjustment of the support force according to the weight of the adapter plate and the requirements of the testing environment.

[0063] Furthermore, the first adjustment hole 11 is a double-layer structure adjustment hole, which includes a lower adjustment hole and an upper adjustment hole stacked together, with the diameter of the upper adjustment hole being larger than that of the lower adjustment hole.

[0064] Specifically, two layers of adjustment holes are provided on the first adjustment plate 10. The upper layer of adjustment holes has a larger diameter and is used for coarse adjustment of the adapter plate's position; the lower layer of adjustment holes has a smaller diameter and a denser spacing, and is used for fine adjustment of the adapter plate's position, improving the accuracy and flexibility of the adjustment. Similarly, double-layer adjustment holes can be provided on the second adjustment plate 20 and the third adjustment plate 30 to achieve the same effect.

[0065] Optionally, a sliding partition is provided between the upper and lower adjustment holes in the double-layer structure. The partition has through holes corresponding to the upper and lower adjustment holes. For coarse adjustments, the partition is slid upwards to fully expose the upper adjustment hole, facilitating quick adjustments using larger diameter bolts. For fine adjustments, the partition is slid downwards to cover most of the upper adjustment hole, leaving only the lower adjustment hole for fine adjustments. Additionally, scale markings are provided on both sides of the partition to help operators accurately determine its position, thereby achieving more precise adjustment control.

[0066] Furthermore, the wall of the first adjustment hole 11 is provided with an elastic liner, which is made of rubber or elastic metal material.

[0067] Specifically, when the bolt passes through the adjustment hole to fix the adjustment plate, the elastic material can provide a certain degree of cushioning and self-adaptation. Even if the equipment experiences slight vibration during testing, the elastic adjustment hole can prevent damage to the bolt and the adjustment hole due to hard friction, while ensuring that the adjustment plate automatically fine-tunes within a certain range, maintaining a good connection between the adapter plate and the test equipment port.

[0068] Optionally, the elastic liner adopts a multi-layer composite structure. The inner layer is made of rubber material, which provides good cushioning performance; the middle layer is an elastic metal mesh, which enhances the overall strength and wear resistance of the elastic liner; and the outer layer is a polytetrafluoroethylene coating, which has the characteristics of low friction coefficient, which can reduce the friction between bolts and elastic liner, and at the same time play a self-lubricating role, making it convenient for bolt installation and removal.

[0069] Optionally, several raised elastic particles are provided on the surface of the elastic liner. When the bolt passes through the elastic liner, the elastic particles will undergo elastic deformation, further increasing the friction and preventing the bolt from loosening. Furthermore, when the test equipment vibrates, the elastic particles can better absorb vibration energy.

[0070] Furthermore, the third adjustment plate 30 has an installation groove 33, the cross-sectional shape of which is adapted to the cross-sectional shape of the test adapter plate 2, and the test adapter plate 2 is installed in the installation groove 33.

[0071] Specifically, the cross-sectional shape of the mounting groove 33 is adapted to the test adapter plate 2. The adapter plate is installed in the groove, and the two fit tightly together, which can prevent the adapter plate from shaking or shifting, protect the adapter plate and the test equipment port, and improve test stability.

[0072] Furthermore, a positioning protrusion is provided inside the mounting groove 33, which is adapted to the groove of the test adapter plate.

[0073] Specifically, the positioning protrusion matches the positioning groove on the test adapter plate 2, which can further accurately position the adapter plate, avoid misalignment during installation, and enhance the fixing effect.

[0074] Optionally, the positioning protrusion has an adjustable height and angle. The bottom of the positioning protrusion is threaded to the bottom of the mounting groove 33, and its height can be adjusted by rotating the positioning protrusion.

[0075] Optionally, a universal ball joint is provided on the top of the positioning protrusion so that the top of the positioning protrusion can rotate flexibly within a certain range to adapt to the grooves at different positions and angles on the test adapter plate 2.

[0076] Optionally, an anti-slip rubber pad can be provided on the surface of the positioning protrusion to increase the friction between it and the groove of the test adapter plate 2, ensuring that the adapter plate will not shift after positioning.

[0077] Furthermore, the wall of the mounting groove 33 is connected with a buffer layer.

[0078] Specifically, the buffer layer can be made of elastic materials such as rubber or silicone, which acts as a buffer when the adapter plate is inserted into the mounting slot 33, preventing damage to the adapter plate due to hard impact. During testing, the buffer layer can also absorb vibrations generated by the equipment, reducing the impact on the adapter plate and protecting the electronic components on the adapter plate. For example, several hemispherical rubber positioning protrusions are evenly distributed on the bottom and sides of the mounting slot 33, and the buffer layer can completely cover the inner surface of the mounting slot 33, with a thickness controlled at 2-3 mm.

[0079] Optionally, the buffer layer adopts a multi-layer structure of different materials. The innermost layer is made of polyurethane foam, which has good cushioning performance and can effectively absorb the impact force when the adapter plate is inserted; the middle layer is made of butyl rubber, which provides good damping characteristics and can reduce the impact of test equipment vibration on the adapter plate; the outer layer is made of silicone coating, which is soft and wear-resistant and can protect the surface of the adapter plate from scratches.

[0080] Optionally, several conical grooves are provided on the surface of the buffer layer, with the tips of the grooves pointing into the mounting groove 33. When the adapter plate is inserted, the grooves can guide the air out, avoiding the difficulty of installing the adapter plate due to air compression. At the same time, the conical grooves can further enhance the buffering effect.

[0081] Furthermore, the side wall of the mounting groove 33 has an opening corresponding to the end of the test adapter plate 2, and the edge of the opening is chamfered.

[0082] Specifically, a guide ramp or chamfer is provided at the entrance of the mounting slot 33 to facilitate the smooth insertion of the test adapter plate 2. The inclination angle of the guide ramp can be designed to be 15-30 degrees, so that the adapter plate can automatically align with the mounting slot 33 when inserted, reducing the difficulty of insertion.

[0083] Optionally, a lubrication layer can be provided inside the mounting slot 33, such as by applying lubricating oil or attaching a self-lubricating material (such as a polytetrafluoroethylene film), to reduce friction when the adapter plate is inserted and removed. This not only improves operating efficiency but also prevents damage to the metal pins or coating on the surface of the adapter plate due to friction.

[0084] Optionally, a foldable guide plate is provided at the opening on the side wall of the mounting slot 33. The guide plate is made of a thin metal sheet and is normally folded onto the side wall of the mounting slot 33 without affecting the normal use of the mounting slot 33; when it is necessary to insert the test adapter plate 2, the guide plate is unfolded, forming an inclined guide channel between the guide plate and the side wall of the mounting slot 33, guiding the adapter plate to be smoothly inserted into the mounting slot 33. A lubricating coating is applied to the surface of the guide plate to further reduce the friction when the adapter plate is inserted.

[0085] Optionally, a rubber strip is provided at the chamfer of the opening edge. The rubber strip has a certain degree of elasticity. When the adapter plate is inserted, the rubber strip can play a buffering role to prevent the adapter plate from colliding with the opening edge and being damaged.

[0086] It is understood that the above embodiments only illustrate preferred embodiments of the present utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the present utility model patent. It should be noted that for those skilled in the art, the above technical features can be freely combined, and several modifications and improvements can be made without departing from the concept of the present utility model, all of which fall within the protection scope of the present utility model.
