[0002] The automotive oil pressure sensor plays a vital role in the vehicle engine system. It monitors the oil pressure within the engine. Different sensor models have different internal structures. The wafer inside the sensor determines whether the sensor can function properly. Failure can affect driving safety, so ensuring the wafer's elasticity is up to standard is crucial. Testing instruments are used to inspect the wafer.

[0003] Since the wafer itself is small in size, it is easy to move out of position during the inspection process, affecting the accuracy of the inspection. Usually, a placement groove with a matching shape is opened on the inspection tool to prevent the wafer position from shifting during the inspection process. However, since the placement groove is similar in shape and size to the wafer, it will be difficult to remove the wafer after inspection, thereby reducing the practicality of the inspection tool.

[0021] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0022] See also Figure 1 - Figure 4 , the utility model provides a technical solution:

[0023] Example 1:

[0024] A tool for testing the elastic force of a wafer of an automotive oil pressure sensor includes a testing tool 1. A placement groove 2 is formed on the top of the testing tool 1. A support plate 3 is provided inside the placement groove 2. A spring 4 is fixedly connected to the top of the support plate 3. A lifting block 5 is fixedly connected to the top of the spring 4. A toggle groove 6 is provided on one side of the testing tool 1. A locking mechanism is provided inside the toggle groove 6.

[0025] The locking mechanism includes a rotating rod 7 fixedly connected to the inner wall of the toggle groove 6, a toggle rod 8 is fixedly connected to the surface of the rotating rod 7, one end of the toggle rod 8 is fixedly connected to a locking block 9, a locking groove 10 for use with the locking block 9 is provided on one side of the jacking block 5, a stop block 11 is fixedly connected to the bottom of the toggle rod 8, and an elastic adjustment mechanism is provided at the bottom of the support plate 3.

[0026] In this embodiment, it is considered that since the placement groove 2 is of similar shape and size to the wafer, it will be difficult to remove the wafer after testing, thereby reducing the practicality of the testing tool 1. Therefore, by providing a locking mechanism, the testing tool 1 can be mounted on the testing instrument by screws, and then the wafer is placed in the placement groove 2. After the test is completed, the toggle rod 8 is pushed upward around the rotating rod 7 to drive the locking block 9 to leave the locking groove 10. At this time, the lifting block 5 is no longer restricted, and the elastic force generated by the spring 4 will drive the lifting block 5 and the wafer to move upward, pushing the wafer out, thereby facilitating the removal of the wafer.

[0027] The problem that the placement groove 2 is similar in shape and size to the wafer, which makes it difficult to remove the wafer after inspection, thereby reducing the practicality of the inspection tool 1, is solved;

[0028] It should be noted that after taking out the disc, press the lifting block 5 downward to a certain position, and then press the toggle rod 8 in the opposite direction so that the locking block 9 at one end of the toggle rod 8 enters the locking groove 10, and the position of the lifting block 5 can be fixed again.

[0029] A guide rod 21 is fixedly connected to the top of the support plate 3 , and a guide hole 22 for use with the guide rod 21 is formed at the bottom of the jacking block 5 .

[0030] In this embodiment, by providing the guide rod 21 and the guide hole 22 , the lifting block 5 can be restricted to move only along the track of the guide rod 21 and the guide hole 22 , thereby improving the stability during the movement.

[0031] Example 2:

[0032] On the basis of Example 1, this embodiment takes into account that the elastic performance of the spring 4 will deteriorate after long-term use, which will make it difficult to push the lifting block 5 to eject the disc. The elastic force adjustment mechanism in this application includes a traction rod 12 arranged on one side of the detection tooling 1, one end of the traction rod 12 passes through the interior of the placement groove 2, and is fixedly connected to the first bevel gear 13, one side of the first bevel gear 13 is meshedly connected to the second bevel gear 14, the top of the second bevel gear 14 is fixedly connected to the screw rod 15, the surface of the screw rod 15 is transmission-connected to the U-shaped slider 16, and the top of the U-shaped slider 16 is fixedly connected to the bottom of the support plate 3.

[0033] In this embodiment, it is considered that the elastic performance of the spring 4 will deteriorate after long-term use, which will make it difficult to push the lifting block 5 to eject the disc. Therefore, by providing an elastic force adjustment mechanism, the twisting block 23 can be rotated to drive the traction block 18, the traction rod 12 and the first bevel gear 13 to rotate. The first bevel gear 13 will drive the second bevel gear 14 to rotate around the bearing 17. The rotation of the bearing 17 will drive the screw rod 15 to rotate, thereby transmitting the U-shaped slider 16 and the support plate 3, so that the support plate 3 moves upward along the trajectory of the limit block 19 and the limit groove 20. After that, when the lifting block 5 reaches the position where the locking block 9 cooperates with the locking groove 10, the elastic force of the compression of the spring 4 will increase, and the disc can be easily ejected.

[0034] The problem that it is difficult to push the lifting block 5 to eject the disc due to the deterioration of the elastic performance of the spring 4 after long-term use is solved.

[0035] A bearing 17 is provided at the bottom of the second bevel gear 14 , and the second bevel gear 14 is rotatably connected to the inner wall of the receiving groove 2 via the bearing 17 .

[0036] In this embodiment, the bearing 17 is provided to support the second bevel gear 14 and the screw rod 15, thereby improving the smoothness of their rotation and ensuring that the first bevel gear 13 and the second bevel gear 14 are always in meshing state.

[0037] Preferably, one end of the traction rod 12 is fixedly connected to a traction block 18 , and one side of the traction block 18 is fixedly connected to a twisting block 23 .

[0038] In this embodiment, by providing the pulling block 18 and the twisting block 23 , it is convenient for the user to twist the rotating rod 7 to rotate, thereby playing a driving role.

[0039] Preferably, both sides of the support plate 3 are fixedly connected to the limiting blocks 19 , and the inner wall of the placement groove 2 is provided with a limiting groove 20 used in conjunction with the limiting blocks 19 .

[0040] In this embodiment, by setting the limit block 19 and the limit groove 20, the moving trajectory of the support plate 3 can be limited when the screw rod 15 transmits the U-shaped slider 16 and the support plate 3, so that it can only move up and down along the trajectory of the limit block 19 and the limit groove 20.

[0041] Working principle: The user installs the detection tool 1 on the detection instrument with screws, and then places the wafer in the placement slot 2. After the detection is completed, the user pushes the toggle rod 8 upward around the rotating rod 7, driving the locking block 9 to leave the locking slot 10. At this time, the lifting block 5 is no longer restricted. The elastic force generated by the spring 4 will drive the lifting block 5 and the wafer upward to push the wafer out, thereby facilitating the removal of the wafer.

[0042] Taking into account that the elastic performance of the spring 4 will deteriorate after long-term use, it will make it difficult to push the lifting block 5 to eject the disc. By rotating the twisting block 23, the traction block 18, the traction rod 12 and the first bevel gear 13 can be driven to rotate. The first bevel gear 13 will drive the second bevel gear 14 to rotate around the bearing 17. The rotation of the bearing 17 will drive the screw rod 15 to rotate, thereby transmitting the U-shaped slider 16 and the support plate 3, so that the support plate 3 moves upward along the trajectory of the limit block 19 and the limit groove 20. After that, when the lifting block 5 is in the position where the locking block 9 cooperates with the locking groove 10, the elastic force of the compression of the spring 4 will increase, and the disc can be easily ejected.

[0043] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
