After the snap ring 50 is sleeved on the fixed end of the encoder sensor 5 and the positioning is completed, the fixed end cover 51 is covered on the end of the mounting cylinder seat 8. After the fixed end cover 51 can be engaged with the snap ring 50, the end cover bolts 52 are sequentially inserted into the end cover holes 53 at the edge of the fixed end cover 51 to fasten the fixed end cover 51 to the end of the mounting cylinder seat 8, so that the encoder sensor 5 is fastened inside the mounting cylinder seat 8. The first transmission end of the rotating shaft 4 extends into the mounting cylinder seat 8 along the axis direction of the other port of the mounting cylinder seat 8, so that the first transmission end of the rotating shaft 4 and the sensor shaft 1 at the output end of the encoder sensor 5 are flexibly connected through the flexible connection assembly 10.

[0028] In the present utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the soft connection component 10 includes a toggle member 2 and an elastic contact connector 3, the outer wall of the toggle member 2 is transversely fixed on the end of the sensor shaft 1, the toggle member 2 is embedded in the first transmission end section of the rotating shaft 4 along the radial direction, and the outer wall of the toggle member 2 and the inner wall of the first transmission end section of the rotating shaft 4 are in a soft connection state through the elastic contact connector 3, and a sleeve hole 20 that is sleeved on the end of the sensor shaft 1 is provided on the outer wall of the toggle member 2 and along the radial direction, and the toggle member 2 is vertically sleeved and fixed on the end of the sensor shaft 1 through the sleeve hole 20. In the utility model, a threaded fixing hole 21 that passes through the sleeve hole 20 is provided at the center of one end of the toggle member 2 and along the center of the axis, and a threaded fixing hole 21 on the end of the toggle member 2 is provided along the axis. The screw 6 is tightened in the direction of being screwed into the sleeve hole 20, so that the toggle member 2 is fixedly connected to the outer wall of the sensor shaft 1 through the tightening screw 6. After the toggle member 2 is sleeved on the end of the sensor shaft 1 through the sleeve hole 20, the threaded fixing hole 21 on the end of the toggle member 2 is screwed into the sleeve hole 20, so that the toggle member 2 is fixed to the sensor shaft 1 through the tightening screw 6. The outer wall of the toggle member 2 is embedded in the second rotating end section of the rotating shaft 4 and is in a soft connection state. After the outer wall of the toggle member 2 is covered with the elastic contact connector 3, the elastic contact connector 3 is squeezed and embedded in the second rotating end section of the rotating shaft 4, thereby forming a soft connection state, which can offset the eccentricity between the rotating shaft 4 and the sensor shaft 1 caused by insufficient processing accuracy, thereby avoiding damage to the encoding sensor 5.
[0029] In the present utility model, if Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, a fixed connecting head 40 protruding in the radial direction is provided at the first transmission end of the rotating shaft 4, and a positioning receiving cavity 41 for accommodating the toggle member 2 is opened on the fixed connecting head 40, and the toggle member 2 is embedded in the positioning receiving cavity 41 along the radial direction, and one end or the outer wall of the entire toggle member 2 is softly connected to the inner wall of the positioning receiving cavity 41 through an elastic contact connecting member 3; the side wall of the positioning receiving cavity 41 on the fixed connecting head 40 and the two ends along the same radial direction respectively have a first positioning opening 41a and a second opening 41b that penetrates the inside and outside of the positioning receiving cavity 41, and the circumferential outer wall of the end (first end) of the toggle member 2 away from the side of the threaded fixing hole 21 is provided with an annular positioning groove 22 for sleeve-mounting the elastic contact connecting member 3, the first end of the toggle member 2 is softly connected to the inner wall of the first positioning opening 41a through the elastic contact connecting member 3 on the annular positioning groove 22, and the second end of the toggle member 2 is arranged at the first In the second opening 41b, the toggle member 2 is clamped in the first clamping port 41a of the fixed connecting head 40 through the elastic contact connecting member 3, so that one end of the toggle member 2 can be in elastic, tight and soft contact or soft connection with the inside of the first clamping port 41a through the elastic contact connecting member 3, and the other end of the toggle member 2 is arranged in the second opening 41b without contact. When the rotating shaft 4 rotates, the toggle member 2 can be toggled through the first clamping port 41a of the fixed connecting head 40, and the sensor shaft 1 is driven by the toggle member 2, so that the measurement signal is collected through the encoding sensor 5, and the rotation of the sensor shaft 1 is completed. It can be used for logging machines to measure the diameter of wood and the cutting length, etc. The connection structure can drive the encoder shaft to rotate while protecting the shaft well by directly softly connecting the sensor shaft 1 with the rotating shaft 4, reducing the generation of virtual position during rotation, improving the measurement accuracy, and playing a good role as a coupling.
[0030] In the present utility model, if Figure 1 , Figure 5 , Figure 6 and Figure 7 As shown, the accommodation space inside the positioning receiving cavity 41 is gradually increased from the first positioning port 41a to the second opening port 41b, and the size of the second opening port 41b is larger than that of the first positioning port 41a. The two ends of the toggle member 2 are arranged between the first positioning port 41a and the second opening port 41b of the positioning receiving cavity 41. The outer wall of the first end of the toggle member 2 is positioned in the first positioning port 41a through the elastic contact connecting member 3. The second end of the toggle member 2 is arranged in the first positioning port 41a, and the second end of the toggle member 2 does not contact the first positioning port 41a.
[0031] In the present utility model, if Figure 1 , Figure 5 , Figure 6 and Figure 7As shown, the toggle member 2 is snap-fitted into the first clamping port 41a of the fixed connection head 40 through the elastic contact connecting member 3, so that one end of the toggle member 2 can be elastically and closely soft-contacted or soft-connected with the inside of the first clamping port 41a through the elastic contact connecting member 3. The other end of the toggle member 2 is arranged in the second opening port 41b with a larger size and does not make contact. When the rotating shaft 4 rotates, the toggle member 2 can be toggled through the first clamping port 41a of the fixed connection head 40. During the process that the rotating shaft 4 rotates to toggle the toggle member 2, the fixed connection head 40 at the end of the rotating shaft 4 is only soft-connected or closely soft-contacted through the elastic contact connecting member 3 at one end of the toggle member 2. There is a large gap between the other end of the toggle member 2 and the second opening port 41b on the side wall of the clamping receiving cavity 41. A part of the whole toggle member 2 is connected to the clamping receiving cavity 41 inside the fixed connection head 40, reducing the overall contact between the toggle member 2 and the rotating shaft 4. When the two rotating shafts are not concentrically connected, it can avoid damage to the coding sensor, so as to achieve the purpose of driving the sensor shaft 1 to rotate, making its installation and maintenance simpler and faster.
[0032] In the present utility model, as Figure 1 , Figure 5 , Figure 6As shown, the outer wall of the first end of the toggle member 2 is squeezed and positioned in the first positioning port 41a of the positioning receiving cavity 41 by the elastic contact connector 3. After the elastic contact connector 3 is sleeved on the toggle member 2, the elastic contact connector 3 is squeezed and deformed and then squeezed and positioned in the first positioning port 41a, so that a soft connection is formed between the toggle member 2 and the rotating shaft 4, avoiding the formation of a gap between the toggle member 2 and the rotating shaft 4 (no virtual position at the connection), and avoiding the non-concentric installation between the rotating shaft 4 and the sensor shaft 1, which may cause damage to the encoding sensor. On the side walls of the first positioning port 41a, there are respectively symmetrically arranged limit slots 41c for squeezing and positioning the elastic contact connector 3 in the axial direction. After squeezing and deforming the elastic contact connector 3, it is pushed into the limit slots 41c on both sides of the first positioning port 41a, so that the elastic contact connector 3 is squeezed and placed in the limit slots 41c on both sides of the first positioning port 41a. In the utility model, the elastic contact connecting member 3 is an annular rubber ring or an O-ring, the toggle member 2 is a rod, and the rod-shaped member is a solid round rod, a hollow round rod or a polygonal strip rod. When the driving wheel 7 (gear, sprocket or pulley) rotates, it drives the transmission shaft 4 to rotate. The elastic contact connecting member 3 (annular rubber ring or O-ring) is sleeved on the toggle member 2, so that the transmission shaft 4 toggles the toggle member 2, thereby rotating the sensor shaft 1, and the sensor 5 gives a signal through the rotation angle to measure the diameter of the wood or the length of the cut. The elastic contact connecting member 3 (annular rubber ring or O-ring) achieves the effect of soft connection. The width of the positioning cavity 41 (or groove) of the transmission shaft 4 is larger than the diameter of the toggle member 2. If the elastic contact connector 3 (annular rubber ring or O-ring) is not assembled, there will be a large gap between the positioning cavity 41 (or recess) of the transmission shaft 4 and the diameter of the toggle member 2. There will be a virtual position when the transmission shaft 4 rotates back and forth. The outer diameter of the elastic contact connector 3 (annular rubber ring or O-ring) is larger than the positioning cavity 41 (or recess) of the transmission shaft 4. After the toggle member 2 is put on the elastic contact connector 3 (annular rubber ring or O-ring), this gap is filled, ensuring that there is no virtual position between the diameter of the rotating shaft 4 and the toggle member 2 when the rotating shaft 4 rotates. The elasticity of the elastic contact connector 3 (annular rubber ring or O-ring) itself can effectively offset the non-concentricity of the transmission shaft 4 and the sensor shaft 1 due to insufficient machining accuracy, greatly reducing the machining difficulty and avoiding damage to the sensor due to non-concentricity.
[0033] In the present utility model, combined with Figures 1 to 7As shown, the connection process of a connection structure for driving the sensor shaft to rotate of the utility model is further explained. First, the soft connection component 10 is fixed to the sensor shaft 1 of the encoding sensor 5, and the sensor shaft 1 of the encoding sensor 5 is inserted into the interior of the mounting cylinder seat 8 together with the soft connection component 10 from one end of the mounting cylinder seat 8, and the rotating shaft 4 is inserted into the interior of the mounting cylinder seat 8 from the other end of the mounting cylinder seat 8, and the soft connection component 10 is embedded in the clamping receiving cavity 41 in the fixed connection head 40 of the rotating shaft 4, and one end of the toggle member 2 of the soft connection component 10 is located in the second opening 41b and the elastic contact connecting member 3 on the end of the toggle member 2 is squeezed and embedded in the first clamping opening 41a, and the elastic contact connecting member 3 is squeezed and set in the first clamping opening 41a, and the toggle member 2 is set in the first clamping opening 41a of the rotating shaft 4 without a virtual position, so that the sensor shaft 5 forms a soft connection with the rotating shaft 4 through the elastic contact connecting member 3 of the soft connection component 10, After an elastic, tight, soft contact or soft connection is formed between the connecting member 3 and the rotating shaft 4, the fixed end of the encoding sensor 5 is preliminarily positioned and installed in the mounting cartridge seat 8 through the retaining ring 50 and the fixed end cover 51. At this time, after the pressing and shifting member 2 is positioned between the first clamping opening 41a and the second opening 41b, the encoding sensor 5 assembly component preliminarily completed in the mounting cartridge seat 8 can be installed in the required measuring position, and then the bearing 9 is sleeved on the rotating shaft 4 and slidably placed in the mounting cartridge seat 8. At this time, bolts are used to fix the sleeve of the bearing 9 on the rotating shaft 4 and the outer shell of the bearing 9 is fixedly connected to the mounting cartridge seat 8. Finally, the driving wheel 7 is installed on the rotating shaft 4. The driving wheel 7 of the utility model is a gear, a sprocket or a pulley. When the driving wheel 7 drives the rotating shaft 4 to rotate, the rotating shaft 4 drives the sensor shaft 5 to rotate without empty position through the shifting member 2 of the soft connection assembly 10, that is, the connection assembly is completed, so that the encoding measurement signal of the sensor shaft 5 during the rotation process can be collected by the encoding sensor 5.
[0034] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
