[0002] A Y-type compressor is a piston compressor with V-shaped cylinders arranged symmetrically in a Y-shape. It typically employs a double-row or multi-row layout and features a compact structure, low vibration, and stable operation. Therefore, it is widely used in tobacco industry production. For example, Y-type compressors can be used in tobacco drying processes. By driving a heat cycle, precise temperature and humidity control is achieved, providing a stable heat source for the tobacco curing barn and improving drying efficiency.

[0003] As a key component of the compressor, the accurate measurement of the piston rod's displacement is crucial for ensuring the compressor's normal operation. Therefore, in the practical application of Y-type compressors, eddy current sensors are typically used to measure the piston rod's displacement. Currently, most commercially available eddy current sensor adjustment devices are external, making it difficult to accurately locate and monitor the piston rod's displacement within the narrow and complex internal space of a Y-type compressor.

The X-axis adjusting rod is provided with a first external thread. The first movable nut and the first locking nut are both screwed into the first external thread. The second adjusting component is fixedly connected to the first movable nut.

[0009] Furthermore, the second adjustment assembly includes a Y-axis adjustment rod extending along the Y-axis direction, and a Y-axis adjustment member disposed on the Y-axis adjustment rod.

The Y-axis adjustment member can move axially on the Y-axis adjustment rod.

[0010] Furthermore, the Y-axis adjusting component includes a second movable nut and a second locking nut sleeved on the Y-axis adjusting rod. The Y-axis adjusting rod is provided with a second external thread. The second movable nut and the second locking nut are both screwed into the second external thread. The second movable nut is fixedly connected to the first adjusting component.

[0011] Furthermore, the third adjustment component includes a Z-axis adjustment plate and a sensor mounting component. One end of the Z-axis adjustment plate is fixedly connected to the second adjustment component, and the other end extends along the Z-axis direction. The eddy current sensor is disposed on the Z-axis adjustment plate and can move axially on the Z-axis adjustment plate. The sensor mounting component is used to fix the eddy current sensor on the Z-axis adjustment plate or to release the eddy current sensor from the Z-axis adjustment plate.

[0012] Furthermore, the Z-axis adjustment plate is provided with a strip-shaped hole, which extends along the axial direction of the Z-axis adjustment plate. The eddy current sensor passes through the strip-shaped hole and slides in cooperation with it.

[0013] Furthermore, the eddy current sensor is provided with a third external thread, and the sensor mounting component includes a third locking nut disposed at one end of the eddy current sensor that passes through the strip hole, and the third locking nut is screwed to the third external thread.

[0014] Furthermore, the sensor mounting component also includes a fourth locking nut disposed on the eddy current sensor.

(3) The first adjustment component of this device includes an X-axis adjustment rod and an X-axis adjustment piece.

[0019] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-4 This utility model discloses a three-axis adjustment device for an eddy current sensor, which is applied in a Y-type compressor. It includes a support frame 1, a first adjustment component 2, a second adjustment component 3, a third adjustment component 4, and an eddy current sensor 5. The support frame 1 is fixed on the Y-type compressor, the second adjustment component 3 is disposed on the support frame 1, the second adjustment component 3 is disposed on the first adjustment component 2, the third adjustment component 4 is disposed on the second adjustment component 3, and the eddy current sensor 5 is disposed on the third adjustment component 4.

[0021] The first adjustment component 2 adjusts the position of the second adjustment component 3 in the X-axis direction, so that the second adjustment component 3 drives the third adjustment component 4 to adjust its position in the X-axis direction. The third adjustment component 4 drives the eddy current sensor 5 to adjust its position in the X-axis direction, thereby realizing the position adjustment of the eddy current sensor 5 in the X-axis direction.

[0022] The second adjustment component 3 adjusts the position of the third adjustment component 4 in the Y-axis direction, so that the third adjustment component 4 drives the eddy current sensor 5 to adjust its position in the Y-axis direction, thereby realizing the position adjustment of the eddy current sensor 5 in the Y-axis direction.

[0023] The position of the eddy current sensor 5 in the Z-axis direction is adjusted by the third adjustment component 4, thereby enabling the eddy current sensor 5 located inside the Y-type compressor to adjust its position in the X, Y, and Z axes, and thus enabling the eddy current sensor 5 to accurately monitor the displacement of the piston rod of the Y-type compressor.

[0024] In this embodiment, one end of the support frame 1 is fixedly connected to the outer wall of the Y-type compressor, and the other end extends through the window of the Y-type compressor to the piston rod in the Y-type compressor. The first adjustment component 2 is located at the end of the support frame 1 that extends to the piston rod. Thus, through the first adjustment component 2, the second adjustment component 3 and the third adjustment component 4, the eddy current sensor 5 located in the internal space of the Y-type compressor can be adjusted in the X, Y and Z axes, thereby enabling the eddy current sensor 5 to accurately position and monitor the displacement of the piston rod of the Y-type compressor.

[0025] Specifically, in actual implementation, the support frame 1 can be made of square steel, that is, a square steel is fixedly connected to the outer wall of the Y-type compressor, and the square steel is bent and extended through the window of the Y-type compressor to the piston rod in the Y-type compressor.

[0026] By setting the first adjustment component 2 at one end of the square steel extending to the piston rod, setting the second adjustment component 3 on the first adjustment component 2, setting the third adjustment component 4 on the second adjustment component 3, and setting the eddy current sensor 5 on the third adjustment component 4, the eddy current sensor 5 is located in the internal space of the Y-type compressor, so that the eddy current sensor 5 can monitor the displacement of the piston rod in the internal space of the Y-type compressor.

[0027] In this embodiment, the first adjustment component 2 includes an X-axis adjustment rod 21 and an X-axis adjustment member. One end of the X-axis adjustment rod 21 is fixedly connected to the support frame 1, and the other end extends along the X-axis direction. The X-axis adjustment member is disposed on the X-axis adjustment rod 21, and the second adjustment component 3 is fixedly connected to the X-axis adjustment member.

[0028] The position of the second adjustment component 3 in the X-axis direction is adjusted by moving the X-axis adjustment rod 21 axially along the X-axis adjustment component. This causes the third adjustment component 4 to move synchronously in the X-axis direction, and the third adjustment component 4 causes the eddy current sensor 5 to move synchronously in the X-axis direction, thereby adjusting the position of the eddy current sensor 5 in the X-axis direction.

[0029] Specifically, in this embodiment, the X-axis adjusting rod 21 is provided with a first external thread 211, and the X-axis adjusting component includes a first moving nut 22 and a first locking nut 23. The first moving nut 22 and the first locking nut 23 are both sleeved on the X-axis adjusting rod 21 and are screwed to the first external thread 211 on the X-axis adjusting rod 21. The second adjusting component 3 is fixedly connected to the first moving nut 22.

[0030] When the first locking nut 23 is tightened, the axial pressure generated by its contact with the first moving nut 22 fixes the first moving nut 22 onto the X-axis adjusting rod 21. When the first locking nut 23 is loosened, the first moving nut 22 can move axially on the X-axis adjusting rod 21, thereby driving the second adjusting component 3 to move in the X-axis direction. The second adjusting component 3 drives the third adjusting component 4 to move synchronously in the X-axis direction, and the third adjusting component 4 drives the eddy current sensor 5 to move synchronously in the X-axis direction, thereby realizing the position adjustment of the eddy current sensor 5 in the X-axis direction.

[0031] In this embodiment, the second adjustment component 3 includes a Y-axis adjustment rod 31 and a Y-axis adjustment member. The Y-axis adjustment rod 31 extends along the Y-axis direction, and the Y-axis adjustment member is disposed on the Y-axis adjustment rod 31. The Y-axis adjustment member is fixedly connected to the first adjustment component 2. Specifically, the Y-axis adjustment member is fixedly connected to the first moving nut 22, so that when the first moving nut 22 moves axially along the X-axis adjustment rod 21, it drives the second adjustment component 3 to move synchronously in the X-axis direction.

[0032] Since the Y-axis adjusting component is fixedly connected to the first adjusting assembly 2, the Y-axis adjusting component can move axially on the Y-axis adjusting rod 31. Therefore, the Y-axis adjusting rod 31 can move along its own axis on the Y-axis adjusting component. The third adjusting assembly 4 is fixedly connected to the Y-axis adjusting rod 31. Thus, by moving the Y-axis adjusting rod 31 along its own axis, the third adjusting assembly 4 moves synchronously in the Y-axis direction. The third adjusting assembly 4 then drives the eddy current sensor 5 to move synchronously in the Y-axis direction, thereby adjusting the position of the eddy current sensor 5 in the Y-axis direction.

[0033] Specifically, in this embodiment, the Y-axis adjusting rod 31 is provided with a second external thread 311, and the Y-axis adjusting component includes a second moving nut 32 and a second locking nut 33. The second moving nut 32 and the second locking nut 33 are both sleeved on the Y-axis adjusting rod 31 and are screwed to the second external thread 311 on the Y-axis adjusting rod 31.

[0034] The second movable nut 32 is fixedly connected to the first adjusting assembly 2. Specifically, the second movable nut 32 is fixedly connected to the first movable nut 22. When the second locking nut 33 is tightened, the axial pressure generated by its contact with the second movable nut 32 fixes the second movable nut 32 onto the Y-axis adjusting rod 31.

[0035] When the second locking nut 33 is loosened, the second moving nut 32 can move axially on the Y-axis adjusting rod 31. That is, the Y-axis adjusting rod 31 can move relative to the second moving nut 32 along its own axis, thereby driving the third adjusting component 4 to move in the Y-axis direction. The third adjusting component 4 drives the eddy current sensor 5 to move synchronously in the Y-axis direction, thereby realizing the position adjustment of the eddy current sensor 5 in the Y-axis direction.

[0036] In this application, the axial movement of the first movable nut 22 on the X-axis adjusting rod 21 is achieved by screwing the first movable nut 22 onto the first external thread 211. Therefore, it is foreseeable that when the first movable nut 22 is screwed onto the first external thread 211, the first movable nut 22 both rotates on the X-axis adjusting rod 21 and moves axially on the X-axis adjusting rod 21. At this time, driven by the first movable nut 22, the second adjusting component 3, the third adjusting component 4, and the eddy current sensor 5 both rotate around the axis of the X-axis adjusting rod 21 and move in the X-axis direction.

[0037] Similarly, in the second adjustment assembly 3, the Y-axis adjustment rod 31 moves relative to the second moving nut 32 along its own axis by engaging with the second external thread 311 on the Y-axis adjustment rod 31. Therefore, it can be foreseen that in the second adjustment assembly 3, the Y-axis adjustment rod 31 moves relative to the second moving nut 32 along its own axis by rotating the Y-axis adjustment rod 31 and keeping the second moving nut 32 fixed. At this time, driven by the Y-axis adjustment rod 31, the third adjustment assembly 4 and the eddy current sensor 5 both rotate around the axis of the Y-axis adjustment rod 31 and move in the Y-axis direction.

[0038] Based on the above technical solution, it can be foreseen that the position adjustment of the eddy current sensor 5 in the X, Y, and Z axes by this three-axis adjustment device is a fine adjustment within a small range. That is, by rotating the first moving nut 22 on the X-axis adjusting rod 21 within a small range, the first moving nut 22 moves within a small range in the X-axis direction, thereby achieving a fine adjustment of the position of the eddy current sensor 5 in the X-axis direction.

[0039] By rotating the Y-axis adjusting rod 31 within a small range on the second moving nut 32, the Y-axis adjusting rod 31 can move within a small range in the Y-axis direction relative to the second moving nut 32, thereby achieving fine adjustment of the position of the eddy current sensor 5 in the X-axis direction. Specifically, in this application, the first moving nut 22, the first locking nut 23, the second moving nut 32, and the second locking nut 33 can all be fine-pitch nuts, and the first external thread 211 and the second external thread 311 can both be fine-pitch threads.

[0040] As the first movable nut 22 rotates, it also causes the eddy current sensor 5 to rotate in the two-dimensional plane space formed by the Y-axis and Z-axis; the rotation of the Y-axis adjusting rod 31 also causes the eddy current sensor 5 to rotate in the two-dimensional plane space formed by the X-axis and Z-axis. Therefore, the X-axis displacement generated by the eddy current sensor 5 during rotation, together with the X-axis position adjustment of the eddy current sensor 5 by the first movable nut 22, together form the adjusted position of the eddy current sensor 5 in the X-axis direction of this device.

[0041] The Y-axis displacement generated during the rotation of the eddy current sensor 5, together with the Y-axis position adjustment of the eddy current sensor 5 by the Y-axis adjustment rod 31, together form the adjusted position of the eddy current sensor 5 in the Y-axis direction of this device.

[0042] The Z-axis displacement generated during the rotation of the eddy current sensor 5, together with the Z-axis position adjustment of the eddy current sensor 5 on the third adjustment component 4, together form the adjusted Z-axis position of the eddy current sensor 5 in this device.

[0043] In this embodiment, the third adjustment component 4 includes a Z-axis adjustment plate 41 and a sensor mounting component. One end of the Z-axis adjustment plate 41 is fixedly connected to the second adjustment component 3, and the other end extends along the Z-axis direction. Specifically, one end of the Z-axis adjustment plate 41 is fixedly connected to the Y-axis adjustment rod 31, and the other end extends along the Z-axis direction.

[0044] The eddy current sensor 5 is mounted on the Z-axis adjustment plate 41 and can move axially on the Z-axis adjustment plate 41. The sensor mounting piece is used to fix the eddy current sensor 5 on the Z-axis adjustment plate 41 or to release the eddy current sensor 5 from the Z-axis adjustment plate 41.

[0045] When the sensor mounting component releases the eddy current sensor 5 from the Z-axis adjustment plate 41, the eddy current sensor 5 can move axially on the Z-axis adjustment plate 41, thereby adjusting the position of the eddy current sensor 5 in the Z-axis direction.

[0046] After the position of the eddy current sensor 5 in the Z-axis direction is adjusted, the eddy current sensor 5 is fixed on the Z-axis adjustment plate 41 by the sensor mounting component, so that the adjusted Z-axis position of the eddy current sensor 5 is fixed, thereby enabling the eddy current sensor 5 to accurately position and monitor the displacement of the piston rod of the Y-type compressor.

[0047] Specifically, in this embodiment, a strip-shaped hole is provided on the Z-axis adjustment plate 41. The strip-shaped hole extends along the axial direction of the Z-axis adjustment plate 41. Since the Z-axis adjustment plate 41 extends along the Z-axis direction, the strip-shaped hole extends along the Z-axis direction on the Z-axis adjustment plate 41.

[0048] The eddy current sensor 5 passes through the strip hole and slides with the strip hole, so that when the sensor mounting part releases the eddy current sensor 5 from the Z-axis adjustment plate 41, the eddy current sensor 5 can move along the strip hole, thereby realizing the position adjustment of the eddy current sensor 5 in the Z-axis direction.

[0049] Specifically, in this embodiment, the eddy current sensor 5 is provided with a third external thread 51, and the sensor mounting component includes a third locking nut 42. The third locking nut 42 is disposed at one end of the through-hole of the eddy current sensor 5 and is screwed to the third external thread 51 on the eddy current sensor 5. Thus, when the third locking nut 42 is screwed to the third external thread 51 and abuts against the Z-axis adjusting plate 41, the eddy current sensor 5 is fixed on the Z-axis adjusting plate 41; when the third locking nut 42 is screwed to the third external thread 51 and moves away from the Z-axis adjusting plate 41, the eddy current sensor 5 is released from the Z-axis adjusting plate 41.

[0050] Furthermore, in this embodiment, the sensor mounting component includes a fourth locking nut 43, which is disposed on the eddy current sensor 5 and located on both sides of the Z-axis adjustment plate 41, respectively, along with the third locking nut 42. Thus, by simultaneously screwing the third locking nut 42 and the fourth locking nut 43 onto the third external thread 51 on the eddy current sensor 5, the eddy current sensor 5 is more securely fixed on the Z-axis adjustment plate 41, thereby better fixing the adjusted position of the eddy current sensor 5 and ensuring the positional accuracy of the eddy current sensor 5.

[0051] The above-described contents can be implemented individually or in combination in various ways, and all such variations are within the protection scope of this utility model.
