Description

Technical Field

[0001] The utility model relates to the technical field of switch point detection of automobile oil pressure sensors, in particular to a switch point detection device of an automobile oil pressure sensor. Background Art

[0002] The primary function of an automotive oil pressure sensor (also called an oil pressure switch) is to detect oil pressure and convert it into an electrical signal, which is then transmitted to the control system via signal processing circuitry to ensure the engine operates within the ideal pressure range. When the oil pressure falls below a preset value, the sensor promptly issues an alarm, alerting the driver via the oil fault light on the dashboard. This helps prevent mechanical damage caused by insufficient oil pressure. Therefore, in actual production, oil pressure sensors must undergo 100% switch point testing to ensure adequate engine lubrication, thereby safeguarding vehicle performance and safety.

[0003] Generally, testing tooling and control instruments are used to test the switch points of automobile oil pressure sensors. The detection principle is to input the rated air pressure from the head of the oil pressure sensor, overcome its internal spring force to disconnect the contacts, and the controller records the instantaneous pressure value when the disconnection occurs, that is, the switch point data. However, the position of the automobile oil pressure sensor is easily offset by the testing tooling, which affects the accuracy of the detection. Utility Model Content

DETAILED DESCRIPTION

[0023] 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.

[0024] See also Figure 1 - Figure 5 , the utility model provides a technical solution:

[0025] Example 1:

[0026] A switch point detection device for an automobile oil pressure sensor includes a control instrument 1, a base 2, and a detection tool 3. The control instrument 1 is arranged on one side of the base 2, and the detection tool 3 is fixedly installed on the top of the base 2. The top of the base 2 is fixedly connected to a placement rack 4, and the top of the placement rack 4 is provided with a positioning mechanism.

[0027] The positioning mechanism includes two hydraulic rods 5 fixedly connected to the top of the placement frame 4, the output end of the hydraulic rod 5 is fixedly connected to the transmission block 6, one side of the transmission block 6 is fixedly connected to the adjustment block 7, one side of the adjustment block 7 is provided with two arc-shaped clamping blocks 8, the interior of the adjustment block 7 is provided with an adjustment slot 9, and the interior of the adjustment slot 9 is provided with a transmission mechanism.

[0028] In this embodiment, it is taken into account that the position of the automobile oil pressure sensor is easily offset by the detection tool 3, thereby affecting the detection efficiency. Therefore, by setting a positioning mechanism, it is possible to select the "switch point detection" mode on the control instrument 1, set the detection time, then set the upper and lower pressure limits, then select the switch point normally open / normally closed, select the enable channel, and then connect the switch point signal lines of the detection tool 3 and the control instrument 2. Finally, the automobile oil pressure sensor is placed on the placement rack 4, and the hydraulic rod 5 is started to drive the transmission block 6, the adjustment block 7 and the arc clamping block 8 to move toward the side close to the automobile oil pressure sensor until the two sets of arc clamping blocks 8 clamp the automobile oil pressure sensor. Then, the detection tool 3 is started, and the detection is completed after waiting for the end of the test. Through the clamping of the positioning mechanism, the position of the automobile oil pressure sensor can be effectively avoided from being offset, thereby improving the accuracy of the detection.

[0029] A protective pad 19 is fixedly connected to one side of the arc-shaped clamping block 8 , and the material of the protective pad 19 is rubber.

[0030] In this embodiment, the protective pad 19 is provided to avoid direct hard contact between the arc-shaped clamping block 8 and the automobile oil pressure sensor, thereby playing a protective and buffering role.

[0031] Example 2:

[0032] On the basis of Example 1, this embodiment takes into account the different diameters of automobile oil pressure sensors. If the distances between the same group of arc-shaped clamping blocks 8 cannot be matched, the clamping effect will also be affected. The transmission mechanism in this application includes a threaded rod 10 arranged inside the adjustment groove 9. The surface of the threaded rod 10 is transmission-connected with a moving block 11. One side of the moving block 11 is fixedly connected with a traction block 12. One side of the traction block 12 is fixedly connected to one side of the arc-shaped clamping block 8. The surface of the moving block 11 is provided with a threaded hole 13 for use with the threaded rod 10.

[0033] In this embodiment, taking into account the different diameters of the automotive oil pressure sensors, if the distances between the arc-shaped clamping blocks 8 of the same group cannot match, the clamping effect will also be affected. Therefore, by providing a transmission mechanism, the threaded rod 10 can be driven to rotate by rotating the twisting block 15. As the threaded rod 10 rotates, the external thread on its surface squeezes the internal thread of the threaded hole 13, causing the two moving blocks 11 to move away from each other along the trajectory of the sliding block 17 and the sliding groove 18, thereby driving the traction block 12 and the two arc-shaped clamping blocks 8 to move away from each other, so that the distance between the two arc-shaped clamping blocks 8 matches the diameter of the automotive oil pressure sensor, thereby improving the stability of subsequent clamping;

[0034] The problem that the clamping effect will be affected if the distances between the arc-shaped clamping blocks 8 in the same group cannot be matched due to the different diameters of the automobile oil pressure sensors is solved is solved.

[0035] One end of the threaded rod 10 is provided with a bearing 14 , and is rotatably connected to the inner wall of the adjustment groove 9 through the bearing 14 .

[0036] In this embodiment, the bearing 14 is provided to support the threaded rod 10 and limit the threaded rod 10 to rotate only around the bearing 14, thereby improving the smoothness of the rotation process.

[0037] One end of the threaded rod 10 passes through one side of the adjustment block 7 and is fixedly connected to a twisting block 15 . Twisting grooves 16 are symmetrically formed on the circumferential side of the twisting block 15 .

[0038] In this embodiment, the twisting block 15 and the twisting groove 16 are provided to facilitate the user to rotate the threaded rod 10 , thereby providing the user with a gripping point.

[0039] A sliding block 17 is fixedly connected to one side of the moving block 11 , and a sliding groove 18 for use with the sliding block 17 is formed on the inner wall of the adjusting groove 9 .

[0040] In this embodiment, by providing the sliding block 17 and the sliding groove 18, when the threaded rod 10 rotates to transmit the moving block 11 and other structures, the moving trajectory of the moving block 11 and other structures can be limited, while improving the smoothness of the movement process.

[0041] The two threaded holes 13 are threaded in opposite directions to each other.

[0042] In this embodiment, by setting the two threaded holes 13 to have opposite threads, when the threaded rod 10 rotates, the two moving blocks 11 will move away from each other, thereby increasing the adjustment rate.

[0043] Working principle: The user selects the "switch point detection" mode on the control instrument 1, sets the detection time, and then sets the upper and lower pressure limits. Then, the user selects the normally open / normally closed switch point and the enabled channel. Then, the user connects the switch point signal line of the detection tool 3 and the control instrument 2. Finally, the automobile oil pressure sensor is placed on the placement rack 4, and the hydraulic rod 5 is started to drive the transmission block 6, the adjustment block 7 and the arc-shaped clamping block 8 to move toward the side close to the automobile oil pressure sensor until the two sets of arc-shaped clamping blocks 8 clamp the automobile oil pressure sensor. Then, the detection tool 3 is started and the test is completed after waiting for the end of the test. The clamping of the positioning mechanism can effectively prevent the position of the automobile oil pressure sensor from being offset, thereby improving the accuracy of the test.

[0044] Taking into account the different diameters of automobile oil pressure sensors, if the distances between the same group of arc-shaped clamping blocks 8 cannot match, it will also affect the clamping effect. The screwing block 15 can be rotated to drive the threaded rod 10 to rotate. While the threaded rod 10 rotates, the external thread on its surface will squeeze the internal thread of the threaded hole 13, causing the two moving blocks 11 to move away from each other along the trajectory of the sliding block 17 and the sliding groove 18, thereby driving the traction block 12 and the two arc-shaped clamping blocks 8 to move away from each other, so that the distance between the two arc-shaped clamping blocks 8 matches the diameter of the automobile oil pressure sensor, thereby improving the stability of subsequent clamping.

[0045] It should be noted that the hydraulic rod 5 is a device or equipment existing in the prior art, or a device or equipment that can be realized in the prior art, and the specific composition and principle of the power supply of the hydraulic rod 5 are clear to those skilled in the art, so they will not be described in detail.

[0046] 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.
