Description

Technical Field

[0001] The utility model relates to the technical field of potentiometer brackets, in particular to an adjustable potentiometer bracket. Background Art

[0002] In control systems, angle potentiometers are often used as feedback measurement elements to measure the angular output of servo mechanisms. The accuracy of angle measurement directly affects the design quality of the control system. Usually, after the angle potentiometer is fixed to the servo mechanism through the potentiometer bracket, axial misalignment or axial angle is easily generated between its shaft and the servo mechanism angular output shaft, resulting in a large error between the measured angle and the actual angle.

[0003] The Chinese patent with the announcement number CN102435134B discloses an adjustable potentiometer bracket, including a transverse fine-tuning block, a longitudinal fine-tuning block and a housing. The transverse fine-tuning block is installed in the inner groove of the longitudinal fine-tuning block, and the longitudinal fine-tuning block is installed in the inner groove of the housing. The transverse fine-tuning block and the longitudinal fine-tuning block, as well as the longitudinal fine-tuning block and the housing are fixed and connected to each other through springs and fine-tuning screws between blind holes.

[0004] The adjustable potentiometer bracket described in the above patent is mainly used to first install the angle measuring potentiometer on the adjustment plate by bolts, and then adjust the position of the potentiometer after installation by adjusting the vertical bolts and the horizontal bolts, so as to reduce the misalignment and axial angle between the potentiometer shaft and the servo mechanism angle output shaft, and reduce the error of the measured angle. However, on the one hand, the angle measuring potentiometer is fixedly connected to the bracket by screwing the bolts, and the whole fixing process is relatively cumbersome, which is not convenient for efficient installation and use of the potentiometer. On the other hand, the installation position of the potentiometer is adjusted by manual screwing fine-tuning, and the adjustment bolts need to be rotated with the help of external tools, which is time-consuming and labor-intensive, and is not convenient for efficient adjustment of the potentiometer position.

[0011] Furthermore, the connecting block is welded to the adjusting seat, and a gap is reserved between the bottom end of the adjusting seat and the support.

[0012] By adopting the above technical solution, it can be ensured that the adjusting seat moves and adjusts synchronously with the connecting block.

[0013] Furthermore, a through hole is provided in the middle of the mounting plate for the angle measuring potentiometer to pass through.

[0014] By adopting the above technical solution, it can be ensured that after the angle measurement potentiometer is installed, the measuring shaft can easily pass through the mounting plate and dock with the shaft of the servo motor.

[0015] Furthermore, the guide block is welded to the mounting plate, the electric push rod is bolted to the adjustment seat and the guide block, and the guide block is slidably connected to the slide groove.

[0018] By adopting the above technical solution, it can be ensured that the clamping plate and the outer wall of the angle measuring potentiometer are fully clamped, so as to achieve stable fixation of the angle measuring potentiometer.

[0019] Furthermore, a battery is embedded in one side of the upper end of the support, and an operation panel is installed on the upper end of the support, located on one side of the battery.

[0020] By adopting the above technical solution, the battery can provide electrical energy for the device to ensure the normal operation of various electrical components.

[0021] Furthermore, the operation panel is electrically connected to the micro motor, the electric push rod and the bidirectional electric slide rail.

[0022] By adopting the above technical solution, the operation panel mainly controls the micro motor, the electric push rod and the bidirectional electric slide rail to open and close in an orderly manner by controlling the on and off of the circuit, so as to achieve efficient installation and adjustment of the potentiometer for angle measurement.

However, on the one hand, the angle measuring potentiometer is fixedly connected to the bracket by screwing the bolts, and the whole fixing process is cumbersome, which is not convenient for efficient installation and use of the potentiometer. On the other hand, the installation position of the potentiometer is adjusted by manually screwing fine adjustment. In order to adjust the position, it is necessary to use external tools to rotate the adjusting bolt, which is time-consuming and labor-intensive, and is not convenient for efficient adjustment of the potentiometer position. The utility model can, on the one hand, realize the rapid clamping and fixation of the potentiometer for angle measurement under the cooperation of the bidirectional electric slide rail and the clamping plate in the clamping mechanism, which is convenient for the efficient installation and use of the potentiometer for angle measurement.
