Description

Technical Field

[0001] The utility model relates to the technical field of vibration detection, in particular to a positioning fixture tooling for vibration detection. Background Art

[0002] In vibration detection, in order to ensure that the installation position and direction of the sensor (such as accelerometer, displacement sensor, etc.) on the object to be measured are accurate and that there is good contact and fixation between the sensor and the object to be measured, so as to obtain accurate and reliable vibration signals, it is usually necessary to clamp the sensor on the object to be measured.

[0003] Existing positioning fixtures for vibration detection mostly use bolt threads to connect the limit baffle to the two sides of the object to be detected. The setting of multiple bolts makes the connection more complicated, and the continuous vibration generated during the detection process will also cause the threaded connection to loosen, which makes it impossible for the sensor to maintain a stable position with the object to be detected, thereby affecting the accuracy of the detection results. Utility Model Content

[0004] 1. Technical Problems Solved

[0005] The technical problem to be solved by the utility model is that the connection efficiency is low and the connection is easy to loosen, which affects the accuracy of the detection result.

[0006] 2. Technical Solution

[0007] In order to solve the above technical problems, the technical solution provided by the utility model is: a positioning fixture tool for vibration detection, including a mounting shell and a sensor, the sensor is connected to the mounting shell, and clamping blocks for clamping the detection component are respectively provided on both sides of the mounting shell, a driving cavity is connected inside the mounting shell, a driving disk is rotatably connected inside the driving cavity, first hinges are respectively hinged on both sides of the driving disk, a second hinge is hinged on the other end of the first hinge, and the other end of the second hinge is hinged to a clamping block, and the clamping blocks are respectively connected to both sides of the mounting shell in a relatively slidable manner; a positioning component for positioning the driving disk is connected to the mounting shell.

[0008] Furthermore, the mounting shell is respectively connected with slide grooves on both sides of the driving cavity, and the slide grooves penetrate the mounting shell. The clamping block is connected with a slider, and the slider slides in cooperation with the slide grooves to guide the clamping block and facilitate the clamping block to clamp the inspection workpiece.

[0009] Furthermore, the clamping block is respectively connected with anti-skid pads on the inner side and the outer side. The anti-skid pads are arranged to increase the friction between the clamping block and the vibration detection workpiece, thereby improving the stability of the clamping limit.

[0010] The cam is provided with a plurality of springs which are connected to the bottom of the cam and are spring-loaded to the bottom of the cam, and the springs are connected to the plurality of springs which are spring-loaded to the bottom of the cam.

[0011] Furthermore, a limiting ball is connected to the top end of the pin shaft. The setting of the limiting ball facilitates limiting the top of the pin shaft to prevent the pin shaft from slipping off the handle, and also facilitates the stretching drive of the pin shaft.

[0012] Furthermore, the connecting shaft is rotatably connected to the mounting shell, and a square hole is penetrated and connected on the driving disk. The middle part of the connecting shaft is a square column structure that cooperates with the square hole. The position of the driving disk is conveniently limited by the matching arrangement of the upper column of the connecting shaft and the upper hole of the driving disk. The driving disk can be driven while the connecting shaft rotates, thereby avoiding invalid rotation of the connecting shaft.

[0025] The matching arrangement of the mounting shell 1, the sensor 2, the clamping block 3, the driving cavity 4, the driving disk 5, the first hinge rod 6 and the second hinge rod 7 in the above structure facilitates the rotation of the driving disk 5. The driving disk 5 drives the clamping blocks 3 to approach each other through the first hinge rod 6 and the second hinge rod 7. The slider 9 and the slide groove 8 are slidably matched to guide the clamping block 3, thereby facilitating the clamping block 3 to rigidly clamp the detection workpiece, so that the sensor 2 is firmly fixed on the detection workpiece, thereby obtaining an accurate and reliable vibration signal.

[0026] Embodiment 2

[0027] Based on the first embodiment, combined with the attached Figure 3 and Figure 4 The mounting shell 1 is connected with a positioning assembly for positioning the driving disk 5, and the positioning assembly includes a connecting shaft 11 connected to the driving disk 5, the connecting shaft 11 is rotatably connected to the mounting shell 1, and a square hole 18 is penetrated and connected on the driving disk 5. The middle part of the connecting shaft 11 is a square column structure that cooperates with the square hole 18, and the other end of the connecting shaft 11 is rotatably penetrated through the mounting shell 1 and is connected with a handle 12 at the end, and a pin 13 is slidably penetrated and connected on the handle 12, and a limiting ball 17 is connected to the top of the pin 13, and a limiting plate 14 is connected to the bottom of the pin 13, and a spring 15 that is sleeved on the outside of the pin 13 is connected between the limiting plate 14 and the handle 12, and the mounting shell 1 is evenly connected to a plurality of limiting grooves 16 circumferentially distributed on the connecting shaft 11, and the limiting grooves 16 cooperate with the bottom of the pin 13.

[0028] The arrangement of the positioning assembly in the above structure facilitates locking the angular position of the drive disk 5 , thereby preventing the drive disk 5 from rotating and displacing during the vibration test, thereby preventing the clamp from loosening.

[0029] The specific usage is as follows:

[0030] When the driving disk 5 needs to be driven, the limiting groove 16 is extended by pulling the pin shaft 13. The setting of the limiting ball 17 is convenient for limiting the top of the pin shaft 13 to prevent the pin shaft 13 from slipping off the handle 12, and it is also convenient for the stretching drive of the pin shaft 13. At this time, the limiting plate 14 rises to compress the spring 15, and then the handle 12 is driven to rotate with the connecting shaft 11 as the axis by driving the pin shaft 13. The connecting shaft 11 drives the driving disk 5 to rotate. The matching setting of the column above the connecting shaft 11 and the hole 18 above the driving disk 5 is convenient for limiting the position of the driving disk 5. While satisfying the rotation of the connecting shaft 11, the driving disk 5 can also be driven to prevent the connecting shaft 11 from rotating ineffectively, thereby facilitating the adjustment of the spacing between the clamping blocks 3 through the first hinge rod 6 and the second hinge rod 7.

[0031] The driving disk 5 drives the first hinge rod 6, and the first hinge rod 6 drives the slider 9 to slide relatively along the slide groove 8 through the second hinge rod 7, and then the slider 9 clamps and limits the detection workpiece through the clamping block 3. The anti-slip pad 10 is provided to facilitate increasing the friction between the clamping block 3 and the vibration detection workpiece, thereby improving the stability of the clamping limit.

[0032] After the clamping block 3 stably clamps the test workpiece, slowly release the pin shaft 13. Under the action of the spring 15, the pin shaft 13 passes through the handle 12 and moves downward until the bottom of the pin shaft 13 cooperates with the limit groove 16, thereby realizing the positioning component to lock the position of the driving disk 5, preventing the driving disk 5 from rotating and displacing during the vibration test and causing the clamping to loosen.
