Description

Technical Field

[0001] This utility model relates to the field of heat pipe testing and positioning technology, specifically a functional testing and positioning fixture. Background Technology

[0002] It is necessary to test the temperature difference between different test points on the processed heat pipe. When locating the test points, a test positioning fixture is required to ensure the accuracy of the positioning.

[0003] When performing functional testing on a heat pipe, different test points need to be tested. During testing, the heat pipe needs to be clamped and fixed. The traditional clamping and fixing method uses a movable clamp, and then a positioning fixture mounted on the movable clamp is used to position the test points on the heat pipe. The positioning fixture is usually connected to the movable clamp with only one set of bolts, which is convenient for adjusting the positioning fixture. However, during the adjustment process, the positioning fixture is prone to rotating along the bolts, causing one side of the fixture to form a certain angle with the side of the movable clamp. When the positioning fixture is used to test the test points of the heat pipe, it will cause the test point position to deviate, affecting the accuracy of the test results. Utility Model Content

[0004] The purpose of this utility model is to provide a functional testing positioning fixture, which restricts the orientation of the adjustment plate by means of a limiting seat. When the limiting seat is engaged with the outside of the movable clamp, it ensures that the adjustment plate is perpendicular to the side of the limiting seat, thereby ensuring that the positioning plate is parallel to the side of the limiting seat and the side of the movable clamp. When the movable clamp is used to clamp and fix the heat pipe, it ensures that the positioning plate can accurately position the test point, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a functional testing positioning fixture, comprising:

[0006] Main structure of the jig;

[0007] The main structure of the fixture includes a positioning plate, an adjustment plate is fixed on one side of the positioning plate, an adjustment groove is provided at the center of the adjustment plate along the length of the adjustment plate, and a limit seat is slidably provided on the adjustment plate;

[0008] The main structure of the fixture is mounted on the movable clamp by locking bolts.

[0009] Preferably, the movable clamp has two sets of threaded holes on its outer side, and the locking bolt passes through the adjusting groove and is threadedly connected to the threaded holes.

[0010] Preferably, the limiting seat is fitted to the outside of the movable clamp, and the limiting seat has a through hole aligned with the threaded hole, with the locking bolt located inside the through hole.

[0011] Preferably, the adjusting plate has a storage groove on the side near the movable clamp, and the limiting seat is movably disposed in the storage groove.

[0012] Preferably, the inner cavity of the storage slot is provided with two sets of sliding grooves, and the inner cavity of the sliding groove is provided with a limiting strip. The opposite side of the limiting strip passes through the sliding groove and is fixed to the outside of the limiting seat.

[0013] Preferably, the inner cavity of the receiving groove is provided with limiting teeth on the side away from the limiting seat, and the outer side of the limiting seat is provided with locking teeth that engage with the limiting teeth.

[0014] Preferably, both the main structure of the fixture and the limiting seat are L-shaped, and the positioning plate is parallel to one side of the limiting seat.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. When the main structure of the fixture and the limiting seat are installed on the movable clamp simultaneously by locking bolts, the limiting seat is made to fit against the side wall of the movable clamp. Then, the limiting seat is used to limit and adjust the adjusting plate to ensure that the positioning plate and the side wall of the movable clamp remain parallel. This ensures that when the movable clamp clamps and fixes the heat pipe, the heat pipe can accurately position the test point under the restriction of the positioning plate, thus ensuring the accuracy of the positioning.

[0017] 2. This utility model ensures the stability between the adjusting plate and the limiting seat through the cooperation of the limiting teeth and the locking teeth, preventing the adjusting plate from still being limited within a certain range even when the locking bolt is loose, and ensuring that the adjusting plate will not slide on the outside of the limiting seat, thus causing a change in the position of the positioning plate.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] This utility model provides, for example Figures 1-4 The functional test positioning fixture shown includes:

[0025] The main structure of the fixture 1 is made of bakelite.

[0026] The main structure 1 of the fixture includes a positioning plate 101, an adjusting plate 102 is fixed on one side of the positioning plate 101, an adjusting groove 2 is provided at the center of the adjusting plate 102 along the length direction of the adjusting plate 102, and a limiting seat 3 is slidably provided on the adjusting plate 102.

[0027] The main structure 1 of the fixture is mounted on the movable clamp 5 by locking bolts 4;

[0028] When the main structure 1 of the fixture and the limiting seat 3 are installed on the movable clamp 5 by tightening the bolt 4, the limiting seat 3 is made to fit against the side wall of the movable clamp 5. Then, the limiting seat 3 is used to limit and adjust the adjusting plate 102 to ensure that the positioning plate 101 and the side wall of the movable clamp 5 remain parallel. This ensures that when the movable clamp 5 clamps and fixes the heat pipe, the heat pipe can accurately position the test point under the restriction of the positioning plate 101, thus ensuring the accuracy of the positioning.

[0029] Among them, such as Figure 2 As shown:

[0030] Two sets of threaded holes 6 are provided on the outer side of the movable clamp 5. The locking bolt 4 passes through the adjustment groove 2 and is threadedly connected to the threaded hole 6. Through the threaded hole 6 provided on the movable clamp 5, the main structure 1 of the fixture can be easily installed on the movable clamp 5 using the locking bolt 4. By tightening or loosening the locking bolt 4, the distance between the positioning plate 101 and the movable clamp 5 can be directly adjusted to adjust the test point of the heat pipe.

[0031] Furthermore, such as Figure 2-4 As shown:

[0032] The limiting seat 3 is attached to the outside of the movable clamp 5. The limiting seat 3 has a through hole 7 aligned with the threaded hole 6. The locking bolt 4 is located in the through hole 7. By setting the through hole 7, when the locking bolt 4 installs the limiting seat 3 on the movable clamp 5, the limiting seat 3 is just attached to the movable clamp 5, ensuring that the limiting seat 3 will not shake. Then, the limiting seat 3 is used to limit the main structure 1 of the fixture.

[0033] Preferred, such as Figure 3 As shown:

[0034] The adjusting plate 102 has a storage groove 8 on the side near the movable clamp 5. The limiting seat 3 is movably installed in the storage groove 8. The storage groove 8 facilitates the storage of the limiting seat 3, ensuring that the limiting seat 3 and the adjusting plate 102 remain stable, so as to prevent the adjusting plate 102 from rotating on the limiting seat 3.

[0035] It is worth noting that, such as Figure 3 As shown:

[0036] The inner cavity of the storage slot 8 is provided with two sets of sliding grooves 9. A limiting strip 10 is slidably provided in the inner cavity of the sliding groove 9. The opposite side of the limiting strip 10 passes through the sliding groove 9 and is fixed to the outside of the limiting seat 3. By sliding the limiting strip 10 in the sliding groove 9, the limiting seat 3 can not only be limited to ensure that the limiting seat 3 will not move out of the storage slot 8, but also assist the sliding adjustment of the limiting seat 3 in the storage slot 8.

[0037] In a further preferred embodiment, such as Figure 3-4 As shown:

[0038] A limiting tooth 11 is provided on the side of the inner cavity of the storage slot 8 away from the limiting seat 3. A locking tooth 12 is provided on the outer side of the limiting seat 3 to engage with the limiting tooth 11. Through the cooperation of the limiting tooth 11 and the locking tooth 12, the stability between the adjusting plate 102 and the limiting seat 3 is ensured, and the adjusting plate 102 can still be limited within a certain range even if the locking bolt 4 is loose. This ensures that the adjusting plate 102 will not slide on the outer side of the limiting seat 3, which would cause the position of the positioning plate 101 to change.

[0039] In addition, such as Figure 3-4 As shown:

[0040] Both the main body structure 1 of the fixture and the limiting seat 3 are L-shaped. The positioning plate 101 is parallel to one side of the limiting seat 3. By setting the shape of the main body structure 1 of the fixture and the limiting seat 3, it is ensured that the limiting seat 3 and the main body structure 1 of the fixture have right angles. Then, by limiting the adjustment plate 102, the parallelism between the positioning plate 101 and the movable clamp 5 can be guaranteed.

[0041] In practical use, the limiting seat 3 is placed in the storage groove 8, and the limiting strip 10 is slidably set in the slide groove 9. Then, the limiting seat 3 is snapped onto the movable clamp 5, aligning the through hole 7 with the threaded hole 6. At the same time, the locking bolt 4 passes through the adjusting groove 2 and through the through hole 7, aligning with the threaded hole 6. The locking bolt 4 is rotated to screw the locking bolt 4 into the threaded hole 6, thereby locking the adjusting plate 102 and the limiting seat 3. While the limiting seat 3 is in contact with the side wall of the movable clamp 5, the limiting seat 3 also limits the adjusting plate 102, ensuring that the positioning plate 101 is parallel to the side wall of the movable clamp 5. When adjusting... After the plate 102 is locked to the limit seat 3, the limit tooth 11 and the locking tooth 12 engage to prevent the adjusting plate 102 from sliding on the limit seat 3. Even if the locking bolt 4 is slightly loose, the adjusting plate 102 will not move due to the restriction of the locking tooth 12 and the limit tooth 11, which would cause the position of the positioning plate 101 to shift. Loosen the locking bolt 4, adjust the distance between the positioning plate 101 and the movable clamp 5, and then tighten the locking bolt 4 again to position the heat pipe test point. When the movable clamp 5 clamps the heat pipe, one end of the heat pipe rests on the positioning plate 101, which can accurately position the test point.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
