Technical Field

[0001] The utility model relates to the technical field of LVDT sensors, and more specifically to a tool for removing a bracket of an LVDT sensor. Background Art

[0002] LVDT is the abbreviation of Linear Variable Differential Transformer, which is a linear displacement sensor. The working principle is simply a core movable transformer. It consists of a primary coil, two secondary coils, an iron core, a coil skeleton, a shell and other components. During the operation of the LVDT, the movement of the iron core cannot exceed the linear range of the coil, otherwise a nonlinear value will be generated, so all LVDTs have a linear range.

[0003] When installing the LVDT sensor, the LVDT sensor needs to be plugged into the mounting surface through the collar bracket. When disassembling, it is difficult to manually disassemble the sensor because the collar bracket is usually clipped into the reserved hole of the mounting surface and the protruding end of the collar bracket is relatively short. Utility Model Content

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an LVDT sensor bracket removal tool. When the ring bracket of the LVDT sensor on the assembly surface needs to be disassembled, the LVDT sensor is first pulled out from the inside of the ring bracket, and then the support frame is placed on the assembly surface, and the through hole of the support frame is arranged on the outside of the ring bracket, and the top plate is pressed down longitudinally relative to the support frame. The reset spring undergoes elastic deformation within the elastic limit, and at the same time, the clamping plates on both sides are slid inwardly along the carrier plate, and the rubber pads on the inner surfaces of the clamping plates are pressed against the outer wall of the ring bracket, which has a good clamping effect. At the same time, under the elastic force of the reset spring, the top plate is lifted longitudinally along the support frame to pull the ring bracket out from the assembly surface, and the disassembly process is more labor-saving.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A LVDT sensor bracket removal tool, comprising a support frame, a through hole is provided on the surface of the support frame, a mounting groove is symmetrically provided on the surface of the support frame, a return spring is fixedly connected inside the mounting groove of the support frame, a support component is installed at the top position of the return spring, and a clamping component is slidably installed on the surface of the support component;

[0007] The support assembly includes a top plate, the top plates are divided into two groups, the inner walls of the two groups of top plates are fixedly connected by a carrier plate, and the surface of the carrier plate is symmetrically provided with sliding grooves;

[0008] The clamping assembly comprises a clamping plate, and a clamping groove is formed on the inner surface of the clamping plate.

[0009] Preferably, the through hole of the support frame is arranged outside the ring bracket.

[0010] Preferably, a guide plate is fixedly connected to the upper surface of the support frame, and a guide groove is provided on the inner wall of the support frame, and a distal end of the guide groove extends to the surface of the guide plate.

[0011] Preferably, a guide block is fixedly connected to the outer surface of the top plate, and the guide block is inserted into the guide groove of the support frame and is slidably connected.

[0012] Preferably, the bottom of the top plate is fixedly connected to the return spring, and the top plate is arranged in parallel with the clamping plate.

[0013] Preferably, a rubber pad is bonded to the clamping groove of the clamping plate.

[0014] Preferably, a push handle is fixedly connected to the upper surface of the clamping plate, and the push handle is located outside the rubber pad.

[0015] Preferably, a groove is formed on the lower surface of the support frame, and a rubber ring is bonded inside the groove of the support frame.

[0016] Preferably, the lower surface of the support frame is symmetrically provided with assembly grooves, and permanent magnets are embedded in the assembly grooves of the support frame, and the permanent magnets are located outside the rubber ring.

[0017] Compared with the prior art, the utility model has at least the following beneficial technical effects:

[0018] (1) When the present scheme requires the disassembly of the collar bracket of the LVDT sensor on the assembly surface, the LVDT sensor is first removed from the collar bracket, and then the support frame is placed on the assembly surface, with the through hole of the support frame arranged outside the collar bracket, and the top plate is pressed down longitudinally relative to the support frame. The reset spring undergoes elastic deformation within the elastic limit, and at the same time, the clamping plates on both sides are slid inwardly along the carrier plate. The rubber pads on the inner surfaces of the clamping plates are pressed against the outer wall of the collar bracket, which has a good clamping effect. At the same time, under the elastic force of the reset spring, the top plate is lifted longitudinally along the support frame, and the collar bracket is pulled out from the assembly surface, making the disassembly process more labor-saving.

[0019] (2) In this solution, a rubber ring is bonded to the lower surface of the support frame, and permanent magnets are symmetrically inlaid on the lower surface of the support frame. When the support frame is placed relative to the assembly surface, the support frame can be magnetically attracted to the assembly surface by the permanent magnets to improve its stability. The friction force of the rubber ring can also provide auxiliary support for the support frame to improve stability. BRIEF DESCRIPTION OF THE DRAWINGS
