Shape measuring assembly

As shown in fig. 11, the shape measuring unit 3 includes a tilt angle measuring unit 31 and a blade measuring unit 32.

As shown in fig. 12, the tilt angle measurement assembly 31 includes a spool post 343 rotatably mounted on the integrated rocker arm carrier 52, and a blade 314 mounted in the spool post 343 for movement with the spool post 343 and for lateral movement relative to the spool post 343; the tooth piece 314 capable of rotating in the measuring plane relative to the rotating shaft of the sliding shaft column 343 is provided with a linear measuring edge on one side or two sides, and the measuring section of the linear measuring edge of the tooth piece 314 is provided with a plurality of sawteeth.

For convenience of describing the form and position relationship, the following explanation is firstly made: in the measuring plane, the connecting line of the tooth tips of the teeth of the tooth piece 314 with a plurality of teeth is a straight line segment, and is marked as a straight line segment A; and the flank wall, which transitions from the tip to the root, forms a valley; meanwhile, the side wall of the piece to be measured corresponding to the cutting edge inclination angle is also a section of straight line segment, and is marked as a straight line segment B. For the cutting edge with a single dip angle, the corresponding straight line section of the side wall with no dip angle (equivalent to the dip angle of 90 degrees) of the cutting edge in the measuring plane is a unified reference datum line; for the cutting edges with double dip angles, taking the central axis of the cutting edge in the measuring plane as a unified reference line; the unified reference line is the reference line O. Based on this, the utility model discloses a theory of operation at blade 314 declination reflection blade inclination as follows: when the straight line segment A is overlapped with the straight line segment B, the included angle between the straight line segment A and the reference line O is equal to the included angle between the straight line segment B and the reference line O, and the deflection angle of the tooth piece 314 is the inclination angle of the cutting edge at the corresponding side of the straight line segment B.

As shown in fig. 16-18, when the inclination angle measuring assembly 31 is used to measure the inclination angle of the cutting edge of the large kitchen knife 100, the initial deflection angle of the tooth 314 is smaller than the inclination angle of the cutting portion of the workpiece, then the measuring section of the linear measuring edge of the tooth 314 is driven to contact with the side wall of the cutting portion of the workpiece and the tooth 314 is driven to linearly approach the workpiece, at this time, the side wall of the cutting portion of the workpiece will push the tooth 314 outwards to rotate along the rotating shaft thereof in the measuring plane, the deflection angle of the tooth 314 will be gradually increased until the measuring section of the linear measuring edge of the tooth 314 just fits the side wall of the cutting portion of the workpiece, the measuring section of the linear measuring edge of the tooth 314 will be driven to contact with the side wall of the cutting portion of the workpiece and the tooth 314 and the workpiece will linearly approach the side wall of a certain sawtooth, at this time, the tip of the cutting portion of the workpiece will be driven to abut against the side wall of a certain sawtooth 314 to make the tooth 314 in a stuck state, the off-angle of the tooth 314 in the critical state or the off-angle of the tooth 314 in the stuck state, that is, the off-angle of the tooth 314 in the measurement suspension state, is obtained, and the off-angle of the tooth 314 in the measurement suspension state can be used for obtaining the inclination angle of the cutting portion of the workpiece.

First, there are several ways to obtain the deflection angle of the blade 314:

firstly, the deflection angle of the tooth plate 314 is directly read manually by comparing the position of the straight measuring edge of the tooth plate 314 through a graduated angle scale;

second, the declination angle of the blade 314 is read directly by an angle sensor;

third, the declination angle of the blade 314 is queried by obtaining the varying parameters of the drive that drives the blade 314 to move linearly.

The first and second are ways of directly reading the deflection angle of the blade 314. The third is the way to calculate the angle of declination of the blade 314.

For the third way of obtaining the deflection angle of the tooth 314 in the stuck state, it is usually assumed that the tilt angle measuring driving device 311 and the integrated linear driving device 56 employ servo motors, and under the condition of the same driving device parameters and tooth 314 parameters, the linear movement distance of the rotating shaft of the tooth 314 and the deflection angle of the tooth 314 have a multi-group one-to-one correspondence relationship, and the corresponding deflection angle of the tooth 314 can be obtained by obtaining the stroke of the moving end of the servo motor. Therefore, multiple sets of corresponding relation data of the servo motor moving end stroke-tooth plate 314 deflection angle can be written into an external controller in advance, and the corresponding servo motor moving end stroke can be obtained only by reading the electric signal parameters of the servo motor in the measuring process, so that the corresponding tooth plate 314 deflection angle is adjusted.

It should be noted that the declination angle of the blade 314 in the initial state may be predetermined, and the declination angle reading is generally known. Therefore, when the inclination angle measuring assembly performs the measurement of the inclination angle of the cutting portion of the workpiece to be measured, the directly read deflection angle of the tooth 314 at the time of measurement suspension may be equal to the inclination angle of the cutting portion of the workpiece to be measured, or the deflection angle of the tooth 314 with respect to the origin may be calculated by calculating the sum of the angle of the tooth 314 from the initial state to the time of measurement suspension and the deflection angle of the tooth 314 at the initial state, thereby calculating the inclination angle of the cutting portion of the workpiece to be measured.

Secondly, there are two cases when the deflection angle of the tooth plate 314 is obtained when the measurement is stopped:

first, the deflection angle of the blade 314 during the critical state is read;

second, the deflection angle of the blade 314 in the stuck state is read.

The case of the deflection angle of the blade 314 in the first reading critical state is suitable for the case of manually reading or recognizing the critical state by using an auxiliary device such as an industrial camera as the measurement suspension state. The second case of the deflection angle of the blade 314 in the stuck state is more suitable for the case of judging the measurement suspended state by using a position sensor such as a touch switch or the like or reading the electromechanical parameters of a servo motor. Further, in the case of the skew angle of the blade 314 in the second reading stuck state, the final measurement accuracy can be improved by adjusting the saw tooth parameter of the blade 314, setting an error compensation parameter, and the like. Two ways of obtaining the timing of the deflection angle of the tooth blade 314 when the measurement is stopped are respectively advantageous and can be selected according to the actual use scene.

As shown in fig. 15, the knife edge measuring assembly 32 includes a knife edge measuring driving device 321 mounted on the integrated bracket 51, a push rod sensor 322 mounted at the linear output end of the knife edge measuring driving device 321, a wheel block 323 mounted at the telescopic end of the push rod sensor 322, and a sheave 324 mounted in the wheel block 323.

In an XYZ coordinate system, the projection of the outer contour of the part to be measured of the measured object on the XZ plane is a line segment, and the projection of the cutting edge of the large kitchen knife on the XZ plane is a straight line segment or an arc segment. The straight line segment includes both an absolute straight line segment and a corresponding approximate straight line segment within the allowable range of machining tolerance. The knife edge measuring driving device 321 can drive the grooved wheel 324 to move linearly in the XY plane along the axial direction of the linear output shaft of the knife edge measuring driving device 321 through the push rod sensor 322 and the wheel clamp 323. When the integrated rocker arm seat 52 is at the origin position, the knife edge measurement driving device 321 can drive the grooved wheel 324 to move along the direction parallel to the X axis through the push rod sensor 322 and the wheel clamp 323, so as to adjust the position of the working end.

The initial position of the grooved wheel 324 is adjusted by the blade-shaped measuring driving device 321, so that the cutting edge of the large kitchen knife 100 as the object to be measured is always in contact with the grooved wheel 324 when passing through the grooved wheel 324 of the blade-shaped measuring driving device 321. In this state, a set of position parameters of the central shaft of the grooved wheel 324 in the time period of the movement of the kitchen knife along the Z axis indirectly reflects the edge shape of the edge of the kitchen knife.

Further, as shown in fig. 14, the inclination angle measuring assembly 31 further includes a pressure plate 350 fixedly connected to the integrated rocker arm base 52 and an angle adjusting bolt 351 mounted on the sliding shaft column 343; one end of the pressure plate 350 is sleeved on the rotating shaft of the integrated rocker arm seat 52 and is provided with an arc-shaped groove, and the other end of the pressure plate 350 extends outwards; the nut of the angle adjusting bolt 351 is positioned in the arc-shaped groove; one end of the wire spring 347 is connected with the sliding shaft column 343, and the other end of the wire spring 347 is connected with the pressing plate 350. Since the angle adjustment screw 351 can only move in the arc-shaped slot, the angle threshold for the deflection of the tooth plate 314 mounted indirectly on the sliding shaft column 343 is limited. The rotational axis of the integrated rocker arm carrier 52 and the rotational axis of the spool post 343 are not coaxial.

Further, as shown in fig. 13, the inclination angle measuring assembly 31 further includes a bushing 342 fitted around the sliding shaft 345; the bushing 342 is mounted on the front end of the sleeve 348 in an interference fit. In this configuration, the bushing 342 and the sliding shaft 345 may be in a clearance fit or a small interference fit. Alternatively, the blade position sensor 346 may be a proximity switch or a distance sensor.

Based on the tooth position sensor 346 using the proximity switch, when the bush 342 is clearance-fitted with the slide shaft 345, the link spring 344 connected between the slide shaft 345 and the slide bushing 348 may be in a natural state of neither tension nor compression in the initial state. When the measuring section of the rack 314 is in contact with the side wall of the cutting edge of the kitchen knife 100, the rack 314 and the sliding shaft 345 can generate a small displacement towards the tail end of the sliding shaft sleeve 348 together, but cannot be in contact with the detecting end of the rack position sensor 346, and only when the tip of the cutting edge of the kitchen knife 100 at the part to be detected is abutted against the side wall of the rack 314 and is in a stuck state, the rack 314 and the sliding shaft 345 further generate a section of displacement towards the tail end of the sliding shaft sleeve 348 together, the detecting end of the rack position sensor 346 can be contacted, and the rack position sensor 346 is triggered to send a signal to an external controller.

Based on the tooth position sensor 346 using the proximity switch, when the bushing 342 is in small interference fit with the sliding shaft 345, in the initial state, the connection spring 344 connected between the sliding shaft 345 and the sliding shaft sleeve 348 is in a slightly compressed state, but the elastic force of the connection spring 344 is smaller than the frictional force between the bushing 342 and the sliding shaft 345 in the interference fit, and the sliding shaft 345 on which the tooth is mounted does not easily slide relative to the sliding shaft sleeve 348. The increased reaction force when the measuring section of the toothed plate 314 is contacted with the side wall of the cutting edge of the large kitchen knife 100 can not make the sliding shaft 345 slide relative to the sliding shaft sleeve 348, the tail end of the sliding shaft 345 can not be contacted with the detecting end of the toothed plate position sensor 346 in these states, only when the tip of the cutting edge of the large kitchen knife 100 to be measured is butted against the side wall of the toothed plate 314 and is in a clamping state, the acting force generated by the clamping state received by the sliding shaft 345 provided with the toothed plate 314 is larger than the friction force between the interference fit bush 342 and the sliding shaft 345, so that the sliding shaft 345 is driven to move towards the tail end of the sliding shaft sleeve 348 and is contacted with the detecting end of the toothed plate position sensor 346, and the toothed plate position sensor 346 is triggered to send a signal to an externally connected controller.

One end of a limit pin 349 in the inclination angle measuring component 31 passes through a limit waist-shaped groove and is fixedly installed on the sliding shaft 345, and the other end of the limit pin 349 is located in the limit waist-shaped groove and can move back and forth in the limit waist-shaped groove. When the limit pin 349 contacts with the front end wall surface of the limit waist-shaped groove, the sliding shaft 345 can be prevented from being separated from the sliding shaft sleeve 348; when the tail end of the sliding shaft 345 just contacts the tooth plate position sensor 346, a gap is formed between the limiting pin 349 and the tail end wall surface of the limiting waist-shaped groove on the side close to the tooth plate position sensor 346, so that the tooth plate position sensor 346 can be protected to a certain extent when the tooth plate 314 is subjected to small-intensity excessive impact.

One of the key technical innovation points of the inclination angle measuring assembly 31 provided in the present embodiment is as follows: the inclination angle measurement of the inclined portion is performed using the blade 314 having a plurality of saw teeth. A plurality of linearly arranged sawteeth form a measuring section on the linear measuring edge of the tooth plate 314; and the rotation axis of the blade 314 is coaxial with the rotation axis of the spool column 343.

When in measurement, the initial deflection angle of the tooth piece 314 is made smaller than the inclination angle of the cutting edge of the large kitchen knife 100, then the measuring section of the linear measuring edge of the tooth piece 314 is driven to contact with the side wall of the cutting edge of the large kitchen knife 100 and the tooth piece 314 is driven to linearly approach the piece to be measured, at this time, the side wall of the cutting edge of the large kitchen knife 100 can outwards push the tooth piece 314 to rotate along the rotating shaft thereof in the measuring plane, the deflection angle of the tooth piece 314 is gradually increased until the measuring section of the linear measuring edge of the tooth piece 314 is just attached to the side wall of the cutting edge of the large kitchen knife 100, the measuring section of the linear measuring edge of the tooth piece 314 is continuously driven to contact with the side wall of the cutting edge of the large kitchen knife 100 and the tooth piece 314 is driven to linearly approach the piece to be measured, at this time, the tip end of the cutting edge of the large kitchen knife 100 can be positioned on the side wall of a certain sawtooth piece 314 to make the tooth piece 314 be in a stuck state, the deflection angle of the tooth piece 314 in a stuck state or the deflection angle in a stuck state in a critical state can be obtained, i.e., the inclination angle of the cutting edge of the large kitchen knife 100 can be obtained. The method adopts unilateral measurement once, and can realize bilateral measurement once left-right measurement twice in the same way.

The deflection angle of the tooth 314 in the critical state or the deflection angle of the tooth 314 in the stuck state is used as the deflection angle of the tooth 314 at the time of measurement suspension. On the one hand, the influence on the accuracy of the measured angle is usually within the practical production tolerance. On the other hand, according to the actual situation, the structure parameters can be adjusted or the measurement precision can be improved by adopting an error compensation mode.

Further, with the solution of providing the tooth position sensor 346, since the sliding shaft 345 mounted with the tooth 314 hits the detecting end of the tooth position sensor 346 and sends a signal to the controller in the stuck state, the solution is more suitable for automatically acquiring the adaptive scene of the deflection angle of the tooth 314 when the measurement is stopped by the controller.

The second important technical innovation point of the technical solution provided in the present embodiment is: the angle of rotation of the teeth 314 can be directly read by a measuring device such as an angle sensor, or can be calculated and obtained by the controller in an analog manner.

The technical solution provided in the embodiment has the following key technical innovation points: the wire spring 347 indirectly provides the toothed plate 314 with a trend of moving towards an original position without deflection all the time through the sliding shaft column 343, so that the toothed plate 314 can be well attached to the inclined part of the cutting edge of the large kitchen knife 100 when the inclination angle is measured.

As shown in fig. 28 and 29, the shape measuring unit 3 includes a tilt angle measuring unit 31 and a blade measuring unit 32 mounted on a middle partition plate 102.

As shown in fig. 30 and 31, the inclination angle measuring assembly 31 includes an inclination angle measuring driving device 311, an inclination angle measuring linear guide pair 312 composed of a sliding table and a linear guide rail which are connected in a sliding manner, a torsion spring 315, a rack holder 313 rotatably mounted on the sliding table through the torsion spring 315, a rack 314 mounted on the rack holder 313, and a rack position sensor 346 capable of identifying a stuck state of the rack 314; the measuring section of the tooth plate 314 is provided with a plurality of saw teeth along a straight measuring edge; the linear guide rail of the inclination angle measurement linear guide rail pair 312 is installed on the intermediate partition plate 102, the inclination angle measurement driving device 311 drives the tooth piece 314 to move linearly through the sliding table of the linear guide rail pair 312, and the tooth piece 314 can rotate in the measurement plane relative to the sliding table through the rack seat 313; in the measuring plane, when the cutting edge of the object to be measured contacts the measuring section of the tooth plate 314, the tooth plate 314 is pushed to rotate to form a deflection angle.

The specific structure of the inclination measuring driving device 311 for driving the tooth piece 314 to linearly move through the sliding table of the linear guide pair 312 may adopt the following typical structures or simple modified structures thereof.

In the first tilt angle measurement driving device 311, the tilt angle measurement driving device 311 directly uses a fixed shaft stepping motor or a through shaft stepping motor, the motor main body is installed on a sliding table, and the motor output shaft is installed in parallel with a linear guide rail. When the fixed shaft stepping motor or the through shaft stepping motor works, the motor main body and the sliding table are linearly moved by the limiting action of the motor output shaft and the linear guide rail, and the tooth piece 314 mounted on the sliding table through the rack holder 313 is linearly moved along with the motor main body and the sliding table.

During initial installation, an initial deflection angle of a certain angle is kept between the tooth piece 314 and the linear guide rail, and the initial deflection angle is smaller than the inclination angle of the part to be measured.

The inclination angle measurement component 31 is arranged independently, so that inclination angle measurement can be carried out, and the edge shape measurement component 32 is arranged independently, so that the outline of the cutting edge can be obtained. The inclination angle measuring component 31 and the edge shape measuring component 32 are arranged simultaneously, so that the edge shape and the inclination angle of the cutting edge of the large kitchen knife serving as a piece to be measured can be obtained simultaneously, and the subsequent operation of polishing the cutting edge is facilitated.

Example 5:

this embodiment proposes another structure of the tool holding assembly 6 on the basis of any one of embodiments 1 to 4.

The tool holding assembly 6 holds the tool assembly 26 laterally and moves the tool assembly 27 vertically.

The transverse clamping tool assembly 26 comprises two clamping pieces, a transverse clamping screw 263 and a transverse clamping driving device 264; an output shaft of the transverse cutter clamping driving device 264 is in transmission connection with one end of a transverse cutter clamping screw rod 263, the transverse cutter clamping screw rod 263 is connected with a jig seat 273 into a whole through a cutter clamping bearing seat arranged on the jig seat 273, and two sections of threads with equal thread pitches and opposite thread directions are arranged on one left side and one right side of the transverse cutter clamping screw rod 263; the left clamping piece 261 and the right clamping piece 262 are respectively in threaded connection with a section of thread on the left and the right, and the left clamping piece 261 and the right clamping piece 262 are respectively in linear sliding connection with the jig seat 273; the transverse clamping driving device 264 drives the left clamping piece 261 and the right clamping piece 262 to move transversely in opposite directions simultaneously through the transverse clamping screw rod 263.

A tool clamping assembly 6 provided with a transverse clamping tool assembly 26 and a vertical moving tool assembly 27; the transverse clamping tool assembly 26 can clamp a tool, and the vertical moving tool assembly 27 can drive the transverse clamping tool assembly 26 to drive the clamped tool to move vertically; the whole process of subsequent blade measurement, blade grinding and cleaning can be completed only by clamping the cutter once when the cutter is placed, so that the consistency of a blade measurement and blade grinding reference system is ensured, and the subsequent blade grinding precision is greatly improved; compared with a structure for storing a plurality of cutters at one time, the cutter taking structure needs to be used for taking the cutters independently every time, and the whole structure is greatly simplified.

Other parts of this embodiment are the same as any of embodiments 1 to 4, and thus are not described again.

Example 6:

this embodiment will be described in comparison with the structure of the inclination angle measuring unit 31 in embodiments 1 and 4.

The inclination angle measuring assembly 31 in embodiment 1 is mounted on the integrated rocker arm seat 52, and the initial angle and position of the tooth plates 314 are adjusted by the external integrated rocker arm seat 52.

The inclination angle measuring assembly 31 of embodiment 4 is installed on the housing, and the initial angle and position of the tooth 314 are adjusted by the adjusting structure of the inclination angle measuring assembly 31 itself.

Further, the same blade 314 structure can be employed in both embodiment 1 and embodiment 4.

In order to facilitate the measurement of the inclination angles of the two sides of the cutting edge, two tooth plates 314 may be arranged on the left and right sides, and a measurement section with a linear measurement edge may be arranged on the opposite side of the two tooth plates 314, or measurement sections with linear measurement edges may be arranged on both the left and right sides of one tooth plate 314. Of course, when two left and right teeth 314 are provided, the two teeth 314 need to be staggered one above the other to avoid structural interference.

Usually, the saw teeth adopt triangular teeth. The tail end of the measuring section of the tooth plate 314 is also provided with a tail tooth limiting convex part.

Further, in both of embodiment 1 and embodiment 4, a restoring force is indirectly provided to the blade 314 by the spring. When the tooth plate 314 does not contact the to-be-measured part, the deflection angle of the tooth plate 314 relative to the unified reference at this time is an initial deflection angle, and the initial deflection angle needs to be controlled to be smaller than the inclination angle of the measuring side of the to-be-measured part with a small inclination angle; when the tooth 314 contacts the measuring side of the member to be measured and the distance between the tooth 314 and the member to be measured is continuously shortened, the tooth 314 is pushed outward to make its deflection angle larger. At this time, a restoring force is required to directly or indirectly provide the blade 314 pushed outward with a force urging it to return toward the initial declination angle. The restoring force is supplied to the tooth plate 314 by the wire spring 347 in embodiment 1; the restoring force is provided to the rack 314 by the torsion spring 315 in embodiment 4.

For the structure of the inclination angle measuring unit 31 in embodiment 1, the wire spring 347 may be mounted in any one of the following two typical structures: first, one end of the wire spring 347 is connected to the sliding shaft column 343 of the mounting rack 314, and the other end of the wire spring 347 is fixed to the integrated rocker arm seat 52; secondly, a pressing plate 350 fixedly connected with the integrated rocker arm seat 52 is added, one end of the pressing plate 350 is sleeved on the rotating shaft of the sliding shaft column 343, the other end of the pressing plate 350 is a far end far away from the sliding shaft column 343, one end of the wire spring 347 is connected with the sliding shaft column 343 of the installation tooth piece 314, and the other end of the wire spring 347 is connected with the far end of the pressing plate 350.

On the basis of the second wire spring 347 connection mode, the pressing plate 350 is provided with an arc-shaped groove concentric with the rotation axis of the sliding shaft column 343, and the range of the rotation angle of the sliding shaft column 343 is limited by an angle adjusting bolt 351 penetrating through the arc-shaped groove and mounted on the sliding shaft column 343, so that the range of the rotation angle of the tooth piece 314 is indirectly limited.

For the structure of the inclination angle measuring assembly 31 in embodiment 4, the torsion spring 315 may be used instead of the wire spring 347, and the installation manner of the torsion spring 315 may be any one of the two installation manners of the wire spring 347.

The plurality of saw teeth on the linear measuring edge of the tooth plate 314 are simultaneously contacted with the inclined angle wall surface of the to-be-measured piece to form a critical position, and the cutting edge tip of the to-be-measured piece is collided with the tooth wall of one of the saw teeth when the tooth plate 314 just passes through the critical position and continues to enlarge the deflection angle, so that the tooth plate 314 and the to-be-measured piece cannot continue to shorten the distance and are blocked. Because the precision requirement of the measured inclination angle is not high, the deflection angle of the tooth piece 314 in the clamping state can be used for calculating the inclination angle of the cutting edge of the to-be-measured piece.

Furthermore, in order to identify the stuck state of the blade 314, a sensor may be provided to detect the stuck state of the blade 314 during the continuous linear advancement, and whether the blade 314 is stuck may also be identified by comparing the forward and backward operation states of the driving device.

For example: in embodiment 1, the toothed plate 314 is driven by the integrated linear driving device 56 to move the toothed plate 314 along a straight line toward the workpiece, and the controller can compare the operating state of the integrated linear driving device 56 in real time to identify whether the toothed plate 314 is in a stuck state. In embodiment 4, the rack 314 is driven by the tilt measurement driving device 311 to move the rack 314 along a straight line toward the object to be measured, and the controller can compare the operating status of the tilt measurement driving device 311 in real time to identify whether the rack 314 is in a stuck state.

Another example is: in embodiment 1, the sliding shaft 345 is slidably mounted in the sliding shaft column 343 through the connecting spring 344, the rack 314 is mounted at the front end of the sliding shaft 345, and the rear end of the sliding shaft 345 is disposed corresponding to the rack position sensor 346 mounted at the rear end of the sliding shaft column 343. In the non-stuck state, the rear end of the slide shaft 345 does not contact the detection end of the blade position sensor 346, and a small distance is left. When the deflection angle of the rack 314 gradually increases to a point where the rack 314 is in a stuck state, the rack 314 is pushed to drive the sliding shaft 345 to move backward in the sliding shaft column 343, thereby triggering the rack position sensor 346 to send a signal to the controller. Further, the inclination angle measuring assembly 31 further includes a limit pin 349 and a sliding shaft sleeve 348 sleeved between the sliding shaft 345 and the sliding shaft column 343; a waist-shaped through groove is formed in the sliding shaft sleeve 348, and a limit pin 349 in the waist-shaped through groove is connected with the sliding shaft 345; when the tail end of the sliding shaft 345 just contacts the blade position sensor 346, a gap exists between the limit pin 349 and the wall surface of the kidney-shaped through groove on the side close to the blade position sensor 346. The blade position sensor 346 may be a proximity switch, among others.

On the premise of identifying the stuck state of the tooth 314, the deflection angle of the tooth 314 at the time can be collected through an angle sensor, the deflection angle of the tooth 314 at the time can also be identified through an image identification technology, and the deflection angle of the tooth 314 at the time can also be calculated through the corresponding relation between the deflection angles of a plurality of groups of teeth 314 and the distance for driving the tooth 314 to linearly move by a driving device.

Other parts of this embodiment are the same as those of the above embodiment, and thus are not described again.
