Description

Technical Field

[0001] This utility model relates to the technical field of test fixtures, specifically to an FCT test fixture with automatic clamping function. Background Technology

[0002] FCT test fixtures are mainly used for functional testing of products, such as voltage, current, power, and frequency. FCT test fixtures can test semi-finished or finished products. Nowadays, the control mode of FCT test fixtures is mainly fully automatic. This type of control fixture has a very fast testing speed and accurate test data.

[0003] Currently, in the FCT testing fixture, during product testing, personnel place the product to be tested on the testing table, and then a cylinder drives the pressure plate to move down, thereby pressing the product so that the pins can contact the outside of the product. However, when personnel place the product on the testing table, there is no function to clamp the outside of the product. As a result, when the pressure plate presses the product, the vibration generated by the start of the equipment can cause the product to shift to a certain extent. To address this issue, we propose an FCT testing fixture with an automatic clamping function. Utility Model Content

[0004] The purpose of this invention is to provide an FCT test fixture with automatic clamping function to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an FCT test fixture with automatic clamping function, comprising a test fixture body, the test fixture body including a test platform, a connecting seat fixedly disposed on the surface of the test platform, a square hole opened on the connecting seat, an elongated plate inserted inside the square hole, a limiting block fixedly installed on the outer side of the elongated plate, the limiting block being inserted into the interior of a limiting groove, the limiting groove being opened on the side wall of the square hole, a long rod fixedly installed on the outer side of the elongated plate, one end of the long rod passing through the connecting seat and fixedly connected to a connecting plate on the test platform, a screw engaged with the connecting plate, the screw being fixedly disposed on the end of the shaft of a servo motor, the servo motor being fixedly disposed on the outer side of the fixed seat, the fixed seat being fixedly disposed inside the test platform, a sliding groove opened on the elongated plate, a clamping plate inserted inside the sliding groove, and a fixing member for fastening the position of the clamping plate being disposed on the outer side of the elongated plate.

[0006] As a further preferred embodiment of this technical solution, the outer side of the elongated plate abuts against the inner wall of the square hole, and the outer side of the clamping plate abuts against the inner wall of the sliding groove.

[0007] As a further preferred embodiment of this technical solution, the outer side of the limiting block abuts against the inner wall of the limiting groove, and both the outer sides of the limiting block and the limiting groove are provided with an arc shape.

[0008] As a further preferred embodiment of this technical solution, the limiting blocks are provided in two sets, and the two sets of limiting blocks are symmetrically arranged on the outer side of the elongated plate.

[0009] As a further preferred embodiment of this technical solution, the fixing member includes a column, which is fixedly disposed on the outer side of the clamping plate. The column is inserted into the interior of the limiting hole, which is opened on the outer side of the elongated plate. A threaded hole is opened on the outer side of the elongated plate, and a bolt is engaged with the interior of the threaded hole. The bottom end of the bolt is tightly attached to the outer side of the clamping plate.

[0010] As a further preferred embodiment of this technical solution, the bolt has anti-slip grooves on its outer side, and the anti-slip grooves are evenly distributed on the outer side of the bolt.

[0011] As a further preferred embodiment of this technical solution, an L-shaped groove is provided on the outer side of the clamping plate, a protective pad is inserted inside the L-shaped groove, a groove is provided on the side wall of the L-shaped groove, and magnetic sheets are fixedly provided inside the groove and on the outer side of the protective pad.

[0012] This utility model provides an FCT test fixture with automatic clamping function, which has the following beneficial effects:

[0013] As the product is placed on the test bench surface, the servo motor drives the screw to rotate, causing the connecting plate to move the long rod downwards. The long plate then slides inside the square hole, allowing the clamping plate to fit tightly against the outside of the product. This pre-clamping function prevents the product from shifting due to vibration during startup of the test fixture.

[0014] This utility model is equipped with a fixing component. When the position of the clamping plate needs to be adjusted, the operator pushes the clamping plate so that it slides inside the sliding groove. During this process, the column can move inside the limiting hole, thereby restricting the clamping plate. Then, the bolt engages and rotates in the threaded hole, so that the bottom end of the bolt can fasten the moved clamping plate in position. Attached Figure Description

Detailed Implementation

[0021] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0022] This utility model provides a technical solution: such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown in this embodiment, an FCT test fixture with automatic clamping function includes a test fixture body 1. The test fixture body 1 includes a test platform 2. A connecting seat 3 is fixedly disposed on the surface of the test platform 2. A square hole 4 is opened on the connecting seat 3. An elongated plate 5 is inserted into the square hole 4. A limiting block 6 is fixedly installed on the outer side of the elongated plate 5. The limiting block 6 is inserted into the interior of a limiting groove 7. The limiting groove 7 is opened on the side wall of the square hole 4. A long rod 8 is fixedly installed on the outer side of the elongated plate 5. One end of the long rod 8 passes through the connecting seat 3 and is fixedly connected to the test platform 2. A connecting plate 9 is connected to a screw 10, which is fixedly mounted on the end of the shaft of a servo motor 11. The servo motor 11 is fixedly mounted on the outside of a fixed base 12, which is fixedly mounted inside the test bench 2. A sliding groove 13 is provided on the elongated plate 5, and a clamping plate 14 is inserted into the sliding groove 13. A fixing element for securing the clamping plate 14 is provided on the outside of the elongated plate 5. When a product is placed on the surface of the test bench 2, the servo motor 11 drives the screw 10 to rotate, causing the connecting plate 9 to move the long rod 8 downwards. The elongated plate 5 slides inside the square hole 4, allowing the clamping plate 14 to fit snugly against the outer side of the product. This pre-clamps the product, preventing displacement caused by vibration during startup of the test fixture body 1. The outer side of the elongated plate 5 abuts against the inner wall of the square hole 4, and the outer side of the clamping plate 14 abuts against the inner wall of the slide groove 13, allowing the elongated plate 5 and the clamping plate 14 to move. The outer side of the limiting block 6 abuts against the inner wall of the limiting groove 7. Both the outer sides of the limiting block 6 and the limiting groove 7 are arc-shaped. Two sets of limiting blocks 6 are provided. The limiting blocks 6 are symmetrically arranged on the outer side of the elongated plate 5, which improves the stability of the elongated plate 5 when it moves. The clamping plate 14 has an L-shaped groove 19 on its outer side. A protective pad 20 is inserted into the L-shaped groove 19. A groove is formed on the side wall of the L-shaped groove 19. Magnetic sheets are fixedly arranged in the groove and on the outer side of the protective pad 20. With the action of the L-shaped groove 19 and the protective pad 20, the protective pad 20 can be tightly attached to the outer surface of the object, thus playing a protective role to a certain extent. The magnetic sheets also make it easy for personnel to replace the protective pad 20.

[0023] like Figure 2 , Figure 3 and Figure 5As shown, the fixing component includes a column 15, which is fixedly mounted on the outer side of the clamping plate 14. The column 15 is inserted into the interior of a limiting hole 16, which is located on the outer side of an elongated plate 5. A threaded hole 17 is provided on the outer side of the elongated plate 5, and a bolt 18 is engaged inside the threaded hole 17. The bottom end of the bolt 18 is tightly attached to the outer side of the clamping plate 14. By providing the fixing component, when the position of the clamping plate 14 needs to be adjusted, the operator can adjust the clamping plate 14. 4. Pushing the clamping plate 14 causes it to slide inside the slide groove 13. During this time, the column 15 can move inside the limiting hole 16, thereby restricting the clamping plate 14. Then, the bolt 18 engages and rotates in the threaded hole 17, thereby securing the moved clamping plate 14 in position at the bottom end of the bolt 18. The bolt 18 has anti-slip textures on its outer side, which are evenly distributed on the outer side of the bolt 18 to facilitate the rotation of the bolt 18 by personnel.

[0024] This utility model provides an FCT test fixture with automatic clamping function, and its working principle is as follows:

[0025] In use, after a person places an object on the surface of the test bench 2, the servo motor 11 starts and drives the screw 10 to rotate. This causes the connecting plate 9, positioned on the screw 10, to move the long rod 8 downwards. The elongated plate 5 then slides down inside the square hole 4, while the limiting block 6 moves inside the limiting groove 7. The elongated plate 5 then moves the clamping plate 14 downwards, allowing the protective pad 20 to directly contact the outer surface of the object, thus automatically clamping the object. If the position of the clamping plate 14 needs adjustment, the person... The clamping plate 14 is pushed so that it slides inside the slide groove 13. During this time, the column 15 can move inside the limiting hole 16, thereby restricting the clamping plate 14. Then, the bolt 18 is engaged and rotated in the threaded hole 17, so that the bottom end of the bolt 18 can fasten the moved clamping plate 14 in position. Under the action of the L-shaped groove 19 and the protective pad 20, the protective pad 20 can be closely attached to the outer surface of the object, thereby playing a certain protective role. The magnetic sheet provided can facilitate the replacement of the protective pad 20 by personnel.

[0026] 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.
