DETAILED DESCRIPTION

[0022] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0023] like Figure 1-Figure 9 As shown, a worm tooth removal device described in an embodiment of the present invention includes a body 1, a grinding wheel 24 assembly 2 and a clamping assembly 3, the clamping assembly 3 includes two groups of jaws 31 and two No. 1 brackets 32, the No. 1 bracket 32 ​​is slidably installed on the body 1, and the two groups of jaws 31 are rotatably installed on the two No. 1 brackets 32 respectively, and the grinding wheel 24 assembly 2 includes: a No. 2 bracket 21 slidably installed on the body 1; a No. 1 ring 22 rotatably installed on the No. 2 bracket 21; a plurality of connecting rods 23 installed on the No. 1 ring 22, each of the connecting rods 23 has a different length; a grinding wheel 24 rotatably installed on the connecting rod 23, the size of the grinding wheel 24 on each connecting rod 23 is different, and the length difference after each group of the grinding wheel 24 and the connecting rod 23 is combined is the difference between worms of different specifications.

[0024] Specifically, since the grinding wheel 24 needs to ensure the installation accuracy and stability when grinding the residual teeth, the grinding wheel 24 cannot be easily replaced, so that when the existing device processes the worm, the specifications of the worm are limited and it cannot adapt to worms of various specifications. The use of the device is limited and has certain limitations; The difference in length between each group of the grinding wheels 24 and the connecting rod 23 after being combined is the difference between worms of different specifications, so that after the No. 2 bracket 21 moves to the front, the grinding wheel 24 can just cooperate with the worm; during installation, the worm is placed in the two groups of jaws 31, and the two ends of the worm are clamped by the jaws 31, and then the No. 1 bracket 32 ​​is controlled to slide left and right, driving the jaws 31 and the worm to slide left and right synchronously, and at the same time, the No. 2 bracket 21 is controlled to slide forward, driving the No. 1 ring 22 and the grinding wheel 24 to slide forward synchronously until the grinding wheel 24 contacts one end of the tooth of the worm (taking the left side as an example), and then the jaws 31 are controlled to rotate to drive the worm synchronously, and the grinding wheel 24 is controlled to rotate relative to the connecting rod 23, so as to realize the grinding of the worm. The grinding action is performed, and the No. 1 bracket 32 ​​is controlled to slide to the left, driving the clamping jaw 31 and the worm to slide to the left synchronously until the grinding wheel 24 grinds to the other end of the worm teeth. The residual teeth on the worm can be ground off during the grinding process, and the residual teeth of the worm can be removed. By setting a rotating No. 1 ring 22 and multiple groups of grinding wheels 24, before removing the residual teeth, the No. 1 ring 22 is controlled to rotate, driving the grinding wheel 24 to rotate synchronously around the axis of the No. 1 ring 22 as the center, and the grinding wheel 24 corresponding to the specification of the worm to be processed is rotated to the front to remove the residual teeth of the worm, so that the device can flexibly adapt to worms of various specifications, and there is no need to disassemble and install the grinding wheel 24 according to the specifications of the worm, thereby improving the processing efficiency.

[0025] like Figure 4-Figure 7 As shown, the grinding wheel 24 assembly 2 also includes: a No. 3 bracket 25 slidably mounted on the body 1; a No. 2 circular ring 26 fixedly mounted on the No. 3 bracket 25, and a sieve hole 27 is opened on the inner wall of the No. 2 circular ring 26; a knocking rod 28 slidably mounted on the No. 2 circular ring 26; and a connecting plate 29 detachably mounted on the outer side of the No. 2 circular ring 26, and after the knocking rod 28 knocks the grinding wheel 24, the debris on the grinding wheel 24 falls into the connecting plate 29 through the sieve hole 27.

[0026] Specifically, the connecting rod 23 is slidably connected to the No. 1 ring 22. When the grinding wheel 24 rotates to the frontmost position, the connecting rod 23 can be controlled to extend forward until the grinding wheel 24 contacts the worm. After the residual teeth are removed, the connecting rod 23 can be controlled to slide backward to separate the grinding wheel 24 from the worm. Then the No. 2 bracket 21 is controlled to slide backward to separate the grinding wheel 24 from the worm. Then the connecting rod 23 of the used grinding wheel 24 is controlled to slide backward. Then the No. 1 ring 22 is controlled to rotate, driving the connecting rod 23 and the grinding wheel 24 to rotate above the knocking rod 28. Then the knocking rod 28 is controlled to slide up and down to knock the grinding wheel 24, so that the debris remaining on the grinding wheel 24 falls into the connecting plate 29 through the sieve hole 27, so as to clean the grinding wheel 24 and ensure the cleaning of the grinding wheel 24 when it is used next time.

[0027] like Figure 4-Figure 7As shown, the grinding wheel 24 assembly 2 also includes: an arc plate 216 rotatably mounted on the connecting plate 29, the knocking rod is slidably connected to the arc plate 216, the arc plate 216 rotates to drive the knocking rod to move towards or away from the grinding wheel 24; a plurality of push rods 210 slidably mounted on the No. 1 ring 22, the contact surface between the push rod 210 and the arc plate 216 is an inclined surface, and a No. 4 spring 217 is installed between the push rod 210 and the No. 1 ring 22; and a No. 1 spring 211 fixedly mounted between the connecting plate 29 and the knocking rod 28.

[0028] Specifically, when the first ring 22 drives the grinding wheel 24 to rotate above the striking rod 28, the push rod 210 is driven to rotate synchronously. During the rotation process, the push rod 210 can drive the arc plate 216 to rotate clockwise (in degrees). Figure 4 Taking the perspective as an example), the clockwise rotation of the arc plate 216 can push the knocking rod 28 to move in the direction away from the axis of the No. 1 ring 22. At this time, the No. 1 spring 211 is compressed. When the arc plate 216 is limited by the stroke and cannot rotate any further, the push rod 210 continues to rotate under the drive of the No. 1 ring 22, and the push rod 210 is acted upon by the inclined surface of the arc plate 216 and moves in the direction away from the arc plate 216. At this time, the No. 4 spring 217 is compressed until the push rod 210 is no longer in contact with the arc plate 216. At this time, the grinding wheel 24 rotates to the top of the knocking rod 28, and the push rod 210 recovers under the action of the elastic force of the No. 4 spring 217. At this time, the knocking rod 28 moves in the direction close to the grinding wheel 24 under the action of the elastic force of the No. 1 spring 211, and at the same time, the arc plate 216 rotates counterclockwise to the initial position to achieve the knocking action on the grinding wheel 24.

[0029] like Figure 6 and 7 As shown, the striking rods 28 on the second ring 26 include a plurality of them.

[0030] Specifically, by providing multiple sets of knocking rods 28 and push rods 210, multiple knocking actions can be performed to make the residual debris on the grinding wheel 24 fall off more thoroughly, thereby improving the cleaning effect.

[0031] like Figure 6 and Figure 7 As shown, the grinding wheel 24 assembly 2 also includes: a number of No. 1 baffles 212 fixedly mounted on the No. 1 ring 22, and the number of the No. 1 baffles 212 are distributed in a circular array about the No. 1 ring 22; and a No. 2 baffle 213 slidably mounted on the No. 1 baffle 212.

[0032] Specifically, during the rotation process, the No. 2 baffle plate 213 is controlled to slide relative to the No. 1 slide plate, so that the knocking rod 28, the No. 1 baffle plate 212 and the No. 2 baffle plate 213 can separate several grinding wheels 24. When the No. 2 baffle plate 213 contacts the No. 1 ring 22, a closed space is formed between two adjacent groups of No. 1 baffle plates 212 and No. 2 baffle plates 213, ensuring that debris does not overflow when the knocking rod knocks the grinding wheel 24, avoiding the problem of debris flying onto the clean grinding wheel 24, and ensuring the cleaning effect.

[0033] like Figure 6 and Figure 7 As shown, the grinding wheel 24 assembly 2 also includes: a plurality of protrusions 214 fixedly mounted on the side wall of the No. 2 ring 26, the protrusions 214 are located within the moving range of the No. 2 baffle plate 213, and the number of the protrusions 214 is consistent with the number of the knocking rods 28; and a No. 2 spring 215 mounted between the No. 1 baffle plate 212 and the No. 2 baffle plate 213.

[0034] Specifically, during the rotation of the No. 1 ring 22, the No. 1 baffle plate 212 and the No. 2 baffle plate 213 are driven to rotate synchronously. During the rotation of the No. 2 baffle plate 213 until it passes the knocking rod 28, the No. 2 baffle plate 213 contacts the inclined surface of the convex plate 214. Therefore, the No. 2 baffle plate 213 slides along the inclined surface of the convex plate 214, so that the No. 2 baffle plate 213 slides relative to the No. 1 baffle plate 212, so that the combination of the No. 2 baffle plate 213 and the No. 1 baffle plate 212 contracts. At this time, the No. 2 spring 215 is compressed, so that the No. 2 baffle plate 213 can pass through the knocking rod 28. After passing through the knocking rod 28, the No. 2 baffle plate 213 slides towards the inner wall of the No. 2 ring 26 under the action of the elastic force of the No. 2 spring 215 until it fits with the inner wall of the No. 2 ring 26 again.

[0035] like Figure 1-Figure 3 As shown, the clamping assembly 3 includes: a No. 1 circular plate 33 rotatably mounted on the No. 1 bracket 32, and the clamping jaw 31 is slidably mounted on the No. 1 circular plate 33; a No. 2 circular plate 34 rotatably mounted on the No. 1 circular plate 33, and the No. 2 circular plate 34 is slidably connected to the clamping jaw 31; a plurality of sensors 35 fixedly mounted on the No. 1 circular plate 33; and a contact plate 36 fixedly mounted on the No. 2 circular plate 34, and the contact plate 36 is used to trigger the sensor 35.

[0036] Specifically, the sensor 35 adopts an existing pressure sensor. During installation, the end of the worm is inserted between the jaws 31, and then the second circular plate 34 is controlled to rotate relative to the first circular plate 33, so that the jaws 31 are gradually tightened until the worm is fixed. During the rotation of the second circular plate 34, the contact plate 36 rotates synchronously. During the rotation of the contact plate 36, it contacts the sensor 35. The rotation of the second ring 26 is controlled by the number of triggered sensors 35 to replace grinding wheels 24 of different specifications.

[0037] like Figure 6 , Figure 8 and Fig. 9 As shown, it also includes: a gear 4 rotatably installed on the second bracket 21, a belt for transmission is installed between the gear 4 and the first ring 22; a mounting plate 5 installed on the body 1; a plurality of rack plates 6 slidably installed on the mounting plate 5, the number of the rack plates 6 is consistent with the number of the grinding wheels 24, and the rack plates 6 are used to drive the gear 4 to rotate; a telescopic rod 7 fixedly installed under the rack plate 6, the telescopic rod 7 is controlled by the sensor 35, and after the sensor 35 is triggered, the telescopic rod 7 is controlled to extend.

[0038] Specifically, Figure 7 In the figure, the position without the grinding wheel 24 is the working station, and the grinding wheel 24 with the smallest specification is located below the working station. Each sensor 35 controls the extension of different telescopic rods 7. After the sensor 35 is triggered, the telescopic rod 7 is controlled to extend, driving the rack plate 6 to move upward, so that when the No. 2 bracket 21 moves forward, the gear 4 can contact the rack plate 6 after moving upward, so that the gear 4 rotates, and the gear 4 drives the No. 2 ring 26 and the grinding wheel 24 to rotate through the belt. The smaller the specification of the worm, the more sensors 35 are triggered, the more rack plates 6 are moved upward, and the larger the angle of rotation of the gear 4; through the rack plate 6, according to the specification of the worm, the number of rack plates 6 that move upward is controlled, and the rotation angle of the No. 1 ring 22 and the grinding wheel 24 is controlled, so that the specification of the grinding wheel 24 located at the working station matches the worm.

[0039] like Figure 6 , Figure 8 and Fig. 9 As shown, the mounting plate 5 is connected to the body 1 in an up-and-down sliding manner, the mounting plate 5 has two groups of rack plates 6, which are symmetrically arranged about the mounting plate 5, and the two groups of rack plates 6 are fixedly connected, a rotating rod 8 is rotatably mounted on the No. 2 bracket 21, and a protrusion 9 is provided on the No. 2 bracket 21, and the protrusion 9 is used to limit the rotating rod 8 to rotate only to one side, and the side of the mounting plate 5 close to the clamping assembly 3 is an inclined surface, and a No. 3 spring 10 is installed between the mounting plate 5 and the body 1.

[0040] Specifically, in the process that the No. 2 bracket 21 drives the gear 4 to move closer to the clamping assembly 3, the rotating rod 8 contacts the mounting plate 5 and rotates to pass through the mounting plate 5. When the grinding wheel 24 contacts the worm, the rotating rod 8 passes through the mounting plate 5 and rotates downward under the action of gravity. After the residual teeth of the worm are removed, the No. 2 bracket 21 drives the grinding wheel 24 to move backward, driving the rotating rod 8 to move synchronously. Due to the restriction of the protrusion 9, the worm cannot rotate to one side of the clamping assembly 3. Therefore, in the process that the rotating rod 8 contacts the inclined surface of the mounting plate 5, the mounting plate 5 can be pushed to move downward. At this time, the No. 3 spring 10 is compressed , the mounting plate 5 moves downward, so that the rack plate 6 on the mounting plate 5 moves downward synchronously. For the rack plate 6 connected to the telescopic rod 7 in an extended state, the rack plate 6 does not contact the gear 4. For the rack plate 6 when the telescopic rod 7 is not in an extended state, the rack plate 6 contacts the gear 4. Therefore, the gear 4 rotates a total of one circle during the backward movement and the forward movement, and the grinding wheel 24 rotates one circle with the second ring 26 as the axis. After the residual teeth are removed or before the residual teeth are removed, each grinding wheel 24 can be knocked by the knocking rod 28 to remove the debris on the grinding wheel 24 and then return to its original position.

[0041] like Figure 2 and Figure 8 As shown, the number of the sensors 35 is one less than the number of the grinding wheels 24, and the telescopic rod 7 of the rack plate 6 closest to the clamping assembly 3 is always in an extended state.

[0042] Specifically, since the telescopic rod 7 of the rack plate 6 closest to the clamping assembly 3 is always in an extended state, when there is no sensor 35 triggered, the gear 4 can rotate by an angle to transfer the largest grinding wheel 24 to the work station. At the same time, when the grinding wheel 24 contacts the worm, the gear 4 is in a meshing state with the rack plate 6 to ensure that the grinding wheel 24 will not rotate in the direction of the center of the circle of the No. 1 ring 22 as the axis during the operation of removing the residual teeth of the worm, thereby ensuring that the grinding wheel 24 is always in close contact with the surface of the worm, thereby ensuring the accuracy and efficiency of removing the residual teeth.

[0043] Working principle: During installation, the end of the worm is inserted between the clamping jaws 31, and then the second circular plate 34 is controlled to rotate relative to the first circular plate 33, so that the clamping jaws 31 are gradually tightened until the worm is fixed. During the rotation of the second circular plate 34, the contact plate 36 rotates synchronously, and the contact plate 36 contacts the sensor 35 during the rotation. After the sensor 35 is triggered, the telescopic rod 7 is controlled to extend, driving the rack plate 6 to move upward, so that during the forward movement of the second bracket 21, the gear 4 can contact the upwardly moved rack plate 6, so that the gear 4 rotates, and the gear 4 drives the second bracket 21 through the belt. The ring 26 and the grinding wheel 24 rotate, and according to the specifications of the worm, the number of the rack plate 6 that moves up is controlled, and the rotation angle of the No. 1 ring 22 and the grinding wheel 24 is controlled so that the specifications of the grinding wheel 24 located at the working station match the worm. Then the No. 1 bracket 32 ​​is controlled to slide left and right, driving the clamping jaw 31 and the worm to move left and right synchronously. At the same time, the No. 2 bracket 21 is controlled to slide forward, driving the No. 1 ring 22 and the grinding wheel 24 to slide forward synchronously until the grinding wheel 24 contacts one end of the teeth of the worm (taking the left side as an example), and then the clamping jaw 31 is controlled to rotate to drive the worm synchronously, and the grinding wheel 24 is controlled to rotate relative to the connecting rod 23 , that is, the action of grinding the worm is realized, and at the same time, the No. 1 bracket 32 ​​is controlled to slide to the left, driving the clamping claw 31 and the worm to slide to the left synchronously until the grinding wheel 24 grinds to the other end of the worm teeth. The residual teeth on the worm can be ground off during the grinding process, and the residual teeth of the worm can be removed. After completion, the No. 2 bracket 21 drives the grinding wheel 24 to move backward, driving the rotating rod 8 to move synchronously. Due to the limitation of the protrusion 9, the worm cannot rotate to one side of the clamping assembly 3. Therefore, during the process of the rotating rod 8 contacting the inclined surface of the mounting plate 5, the mounting plate 5 can be pushed downward. At this time, the No. 3 spring 10 is compressed, and the mounting plate 5 moves downward, so that the rack plate 6 on the mounting plate 5 moves downward synchronously. For the rack plate 6 connected to the telescopic rod 7 in the extended state, the rack plate 6 does not contact the gear 4. For the rack plate 6 when the telescopic rod 7 is not in the extended state, the rack plate 6 contacts the gear 4. Therefore, in the process of the gear 4 moving backward and forward, the gear 4 rotates a total of one circle, so that the grinding wheel 24 rotates a circle with the second ring 26 as the axis. After the residual teeth are removed or before the residual teeth are removed, each grinding wheel 24 can be knocked by the knocking rod 28 to remove the debris on the grinding wheel 24 and then return to its original position.
