Description

Technical Field

[0001] This utility model relates to the technical field of eddy current sensor support tube clamping device, and in particular to eddy current sensor support tube clamping device. Background Technology

[0002] According to Faraday's principle of electromagnetic induction, when a metallic conductor (whether in block form or not) is placed in a changing magnetic field, or moves within a magnetic field cutting magnetic field lines (note that cutting a constant magnetic field does not generate eddy currents), induced currents in the form of eddy currents are generated inside the conductor. These currents are called eddy currents, and the corresponding phenomenon is the eddy current effect. Sensors that utilize the eddy current effect are called eddy current sensors. The core working principle of these sensors is based on the eddy current effect, enabling them to accurately measure the relative position between the object being measured and the sensor probe surface.

[0003] In the aforementioned technologies, the probe of an eddy current sensor is usually supported by a support tube. However, in actual use, without a clamping device, the force distribution at the connection point of the support tube is uneven and fluctuates, which can easily lead to local stress concentration and make it inconvenient to use. Therefore, an eddy current sensor support tube clamping device is proposed to solve the above problems. Summary of the Invention

[0004] To overcome the above deficiencies, this utility model provides a clamping device for the support tube of an eddy current sensor, which aims to solve the problem that in the absence of a clamping device, the force distribution at the connection point of the support tube is uneven and fluctuates, which can easily lead to local stress concentration.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an eddy current sensor support tube clamping device, including a fixed end, a support tube detachably connected inside the fixed end, a disassembly component provided on the rear wall of the fixed end, a clamping component provided on the rear wall of the disassembly component, and a retaining ring fixedly connected to the outer wall of the support tube;

[0006] The clamping assembly includes a ring, a connecting block is fixedly connected to the outer wall of the ring, a connecting column is elastically connected to the inside of the ring by a buffer spring, and an arc-shaped clamping block is fixedly connected to the outer wall of the connecting column.

[0007] As a further description of the above technical solution:

[0008] One end of the buffer spring is fixedly connected to the inside of the ring, and the other end of the buffer spring is fixedly connected to the outer wall of the connecting column.

[0009] As a further description of the above technical solution:

[0010] The arc-shaped clamps are provided in multiple sets, and the multiple sets of arc-shaped clamps are distributed in a ring along the central axis of the ring.

[0011] As a further description of the above technical solution:

[0012] The connecting blocks are provided in multiple sets, and the multiple sets of connecting blocks are distributed in a ring along the central axis of the ring.

[0013] As a further description of the above technical solution:

[0014] The disassembly assembly includes a retaining ring, and a retaining block is elastically connected inside the retaining ring by a spring. The outer wall of the retaining ring has a retaining groove.

[0015] As a further description of the above technical solution:

[0016] The front end of the connecting block is fixedly connected to the outer wall of the fixing ring.

[0017] As a further description of the above technical solution:

[0018] One end of the spring is fixedly connected to the inside of the fixing ring, and the other end of the spring is fixedly connected to the rear wall of the locking block.

[0019] As a further description of the above technical solution:

[0020] The outer wall of the card block is engaged inside the card slot, and the rear wall of the fixing ring is fixedly connected to the outer wall of the fixing end.

[0021] This utility model has the following beneficial effects:

[0022] In this utility model, by setting buffer springs, connecting columns, and arc-shaped clamps, multiple sets of annularly distributed arc-shaped clamps can form a uniform and tight clamping force on the support tube from different directions under the action of buffer springs. This achieves the effect of adapting to the size error or slight deformation of the support tube, and the buffer springs absorb the impact force to avoid damage to the tube wall.

[0023] In this utility model, by setting a fixing ring, a spring, and a locking block, when the support tube is inserted into the fixed end, the locking block inside the fixing ring automatically extends under the action of the spring and locks into the locking groove of the locking ring, forming a mechanical locking fit. This achieves the effect of quick disassembly and replacement when the support tube is damaged, thanks to the locking structure. Attached Figure Description

[0032] The clamping assembly 3 includes a ring 31. A connecting block 35 for connecting the ring 31 and the disassembly assembly 4 is fixedly connected to the outer wall of the ring 31. A connecting post 33 for transmitting the elastic force of the buffer spring 32 is elastically connected to the inside of the ring 31 through a buffer spring 32. An arc-shaped clamping block 34 for directly contacting and clamping the support tube 2 is fixedly connected to the outer wall of the connecting post 33 through a buffer spring 32. One end of the buffer spring 32 is fixedly connected to the inside of the ring 31, and the other end of the buffer spring 32 is fixedly connected to the outer wall of the connecting post 33. The arc-shaped clamping block 34 is connected to the inside of the ring 31 of the clamping assembly 3 through multiple sets of buffer springs 32. When the support tube 2 is inserted into the ring 31, the arc-shaped clamping block 34 is tightly attached to the outer wall of the support tube 2 under the elastic force of the buffer spring 32. The multiple sets of annularly distributed arc-shaped clamping blocks 34 apply clamping force to the support tube 2 from different directions to achieve elastic clamping of the support tube 2.

[0033] Reference Figures 2-4Multiple sets of arc-shaped clamping blocks 34 are provided, and these multiple sets of arc-shaped clamping blocks 34 are distributed in a ring along the central axis of the ring 31, clamping the support tube 2 from multiple directions. Multiple sets of connecting blocks 35 are provided, and these multiple sets of connecting blocks 35 are distributed in a ring along the central axis of the ring 31, making the connection between the ring 31 and the fixing ring 41 more stable. The disassembly assembly 4 includes a fixing ring 41. Inside the fixing ring 41, a locking block 43 for engaging with the locking slot 44 is elastically connected by a spring 42. The outer wall of the locking ring 5 is provided for accommodating the locking block. Block 43 forms a fixed slot 44. The front end of connecting block 35 is fixedly connected to the outer wall of fixed ring 41. Spring 42 provides elastic force to block 43. One end of spring 42 is fixedly connected to the inside of fixed ring 41, and the other end of spring 42 is fixedly connected to the rear wall of block 43. The outer wall of block 43 engages with the inside of slot 44. The rear wall of fixed ring 41 is fixedly connected to the outer wall of fixed end 1. When support tube 2 is inserted into fixed end 1, the retaining ring 5 on its outer wall will cooperate with fixed ring 41. Block 43 inside fixed ring 41 extends outward under the elastic action of spring 42 and just engages with slot 44 on the outer wall of retaining ring 5. Through the engagement of block 43 and slot 44, support tube 2 and fixed ring 41 are firmly connected, thereby fixing support tube 2 inside fixed end 1.

[0034] Working principle: During use, the circular ring 31 of the clamping assembly 3 is connected to the arc-shaped clamping blocks 34 through multiple sets of buffer springs 32. When the support tube 2 is inserted into the circular ring 31, the arc-shaped clamping blocks 34 are tightly attached to the outer wall of the support tube 2 under the elastic force of the buffer springs 32. The multiple sets of annularly distributed arc-shaped clamping blocks 34 apply clamping force to the support tube 2 from different directions, achieving elastic clamping of the support tube 2. When the support tube 2 is inserted into the fixed end 1, the retaining ring 5 on its outer wall will cooperate with the fixed ring 41.

Through the engaging cooperation between the retaining block 43 and the retaining groove 44, the support tube 2 and the fixed ring 41 are firmly connected, thereby fixing the support tube 2 inside the fixed end 1.
