Description

Technical Field

[0001] The present invention belongs to the technical field of wood processing, and particularly relates to a wood surface polishing device and a using method thereof. Background Art

[0002] Due to the characteristics of being natural, environmentally friendly, durable and easy to process, wood is widely used in wooden toys. When processing wood, it needs to go through processing procedures such as wood cutting, wood drying, wood gluing, and wood surface treatment. Among them, when processing the wood surface, polishing can grind the rough wood into a smooth and shiny product.

[0003] Traditional wood polishing is mainly carried out by workers holding a small polishing device to polish the wood. With the development of technology, some devices that can polish wood have emerged. These devices generally first clamp the wood, and then polish the wood surface through a polishing wheel or other polishing structures. However, in one polishing, the clamped part on the same surface cannot be processed. The wood needs to be taken off and reclamped, and then the unprocessed position is polished. Workers need to operate more steps, the processing efficiency is low, and it is also easy to affect the overall polishing accuracy of the same wood surface. Therefore, the existing wood polishing devices still need to be improved. Summary of the Invention

[0004] The purpose of the present invention is to provide a wood surface polishing device and a using method thereof for the above-mentioned existing technical problems. When this polishing device polishes the wood, it can simultaneously polish the clamping points on the wood surface, improving the polishing efficiency of the wood.

[0005] In view of this, the present invention provides a wood surface polishing device, including: At least two positioning seats, which are spaced apart in a first direction and can simultaneously contact the wood; Clamping plates with the same number as the positioning seats, each clamping plate is respectively located above a positioning seat, and the clamping plate can approach and move away from the positioning seat in the vertical direction; A longitudinal pushing mechanism, which can individually drive each clamping plate to approach or move away from the corresponding positioning seat; A polishing mechanism, which includes a polishing wheel and a polishing power source, and the polishing wheel can polish the surface of the wood on the side close to the clamping plate under the drive of the polishing power source; A translation mechanism, which can drive the polishing mechanism to move in the first direction; Wherein, after the clamping plate moves away from the positioning seat, the polishing mechanism can pass through the space between the clamping plate and the wood in the first direction.

[0006] In this technical solution, the wood to be polished is placed on multiple positioning seats, so that the bottom surface of the wood contacts multiple positioning seats simultaneously. Then, the longitudinal pushing mechanism is used to control multiple clamping plates to approach the positioning seats. Finally, the multiple clamping plates cooperate with the multiple positioning seats to clamp the wood at multiple points. Then, the translation mechanism is activated to drive the polishing mechanism to move from one end of the wood to the other end. During this process, the polishing mechanism polishes the upper surface of the wood. When the polishing mechanism approaches a certain clamping point, the clamping plate at this clamping point moves away from the wood under the control of the longitudinal pushing mechanism, so that the polishing mechanism can pass through the space between the clamping plate at this clamping point and the wood, enabling the polishing mechanism to polish the clamping point on the wood. At this time, the wood is still clamped at other clamping points to maintain the stability of the polishing process. After polishing the clamping point, the longitudinal pushing mechanism drives the clamping plate to clamp the wood again. As the polishing mechanism moves in the first direction, the polishing process of each clamping point on the wood is completed in sequence.

[0007] In the above technical solution, further, the translation mechanism includes: A base, the position of the base relative to the positioning seat is fixed; A lead screw, the lead screw is rotationally arranged on the base along the first direction; A translation seat, the translation seat is slidably arranged on the base along the first direction, and a nut in transmission cooperation with the lead screw is arranged on the translation seat; A driving member, the driving member can drive the lead screw to rotate.

[0008] In the above technical solution, further, a fixed seat is slidably arranged on the translation seat along the second direction. A flat push cylinder for driving the fixed seat to move in the second direction is arranged on the translation seat, and the polishing mechanism is arranged on the fixed seat.

[0009] In the above technical solution, further, the polishing mechanism further includes a mounting frame and a power transmission mechanism. The mounting frame is arranged on the fixed seat. The first end of the mounting frame extends beyond the fixed seat in the second direction. A polishing wheel is rotationally arranged at the first end of the mounting frame. A polishing power source is arranged at the second end of the mounting frame. The polishing wheel is connected to the polishing power source through the power transmission mechanism, and the power transmission mechanism can transmit the power output by the polishing power source to the polishing wheel.

[0010] In the above technical solution, further, the mounting frame is slidably connected to the fixed seat along the vertical direction. A screw rod is arranged on the fixed seat along the vertical direction. A threaded hole is arranged on the fixed seat and above the mounting frame. The threaded end of the screw rod is rotationally connected to the mounting frame, and the screw rod is in threaded connection with the threaded hole. A one-way driving mechanism for driving the screw rod to rotate is arranged on the fixed seat, and the one-way driving mechanism can limit the active rotation of the screw rod.

[0011] In the above technical solution, further, the one-way driving mechanism includes: A fixed gear ring, on the inner wall of which fixed teeth are distributed circumferentially, and the fixed gear ring is fixed in position relative to the fixed seat; A connecting column, the connecting column is arranged inside the fixed gear ring, one end of the connecting column is coaxially connected with the fixed end of the screw rod, a mounting block is arranged on the side wall of the connecting column, the mounting block does not contact the fixed tooth in the radial direction of the fixed gear ring, two connecting arms are symmetrically arranged on both sides of the mounting block, there is a spacing between the connecting arms and the side walls of the connecting column, the connecting arms are elastic, a contact block is arranged at one end of the connecting arm away from the mounting block, a side surface of the contact block away from the mounting block contacts the surface of the fixed tooth, and a side surface of the contact block close to the mounting block contacts the tooth tip of the fixed tooth; A driving block, the driving block is arranged on a side of the connecting column away from the screw rod, the driving block and the connecting column are coaxially distributed, an arc block is arranged on the driving block, the arc block can extend into the space between the mounting block and the fixed tooth, and the driving block can bring the arc block into contact with the contact block when rotating in the circumferential direction, and push the connecting arm toward the side wall of the connecting column, so that the side of the contact block away from the mounting block is separated from the surface of the fixed tooth.

[0012] In the above technical scheme, further, it also includes a frame whose position is relatively fixed with respect to the positioning seat, the longitudinal pushing mechanism includes a cylinder assembly and a position sensor, the cylinder assembly is arranged on the frame, the cylinder assembly can drive the plywood to approach or move away from the positioning seat, the position sensor can detect the distance between the plywood and the wood in real time, and control the working state of the cylinder assembly.

[0013] In the above technical solution, further, the cylinder assembly includes a cylinder body, a piston, two pipes arranged at both ends of the cylinder body and connected to the interior of the cylinder body, two solenoid valves respectively arranged on the two pipes, and a controller. The ends of the two pipes away from the cylinder body are connected to an air supply device, the position sensor can transmit a signal to the controller, and the controller can control the working status of the two solenoid valves.

[0014] The present invention also discloses a method for using the polishing device, which comprises the following steps: Step 1: Move the polishing mechanism to the initial position through the translation mechanism, place the wood to be polished on multiple positioning seats at the same time, and drive multiple clamps to approach the corresponding positioning seats through the longitudinal push mechanism, so that the multiple clamps cooperate with the multiple positioning seats to clamp the wood; Step 2: Start the polishing mechanism and the translation mechanism, so that the polishing mechanism starts to polish the surface of the wood close to the plywood from the end of the wood, and the translation mechanism drives the polishing mechanism to move toward the other end of the wood in the first direction; Step 3: When the polishing mechanism approaches a clamping point, the translation mechanism first controls the polishing mechanism to pause at the current position. Then, the longitudinal pushing mechanism drives the clamping plate at this clamping point away from the corresponding positioning seat, so that the distance between the clamping plate and the wood is greater than the width of the polishing mechanism in the vertical direction. Then, the translation mechanism continues to drive the polishing mechanism to pass through the space between the clamping plate and the wood at this clamping point. During this process, the polishing mechanism polishes the clamping point on the upper surface of the wood. Step 4: After the polishing mechanism completely passes through this clamping point, the translation mechanism first controls the polishing mechanism to pause at the current position. The longitudinal pushing mechanism drives the clamping plate at this clamping point close to the wood, and makes the clamping plate at this clamping point cooperate with the corresponding positioning seat to clamp the wood again. Then, the translation mechanism continues to drive the polishing mechanism to move in the first direction. Step 5: Repeat Step 3 and Step 4 to complete the polishing treatment of the entire upper surface of the wood.

[0015] The beneficial effects of the present invention are as follows: 1. Through the cooperation of multiple positioning seats, multiple clamping plates, and the longitudinal pushing mechanism, multi-point clamping can be achieved when clamping the wood. The polishing mechanism can move from one end of the wood to the other end under the drive of the translation mechanism. Each time the polishing mechanism reaches a clamping point during the moving process, the clamping plate at the corresponding clamping point can be driven away from the wood separately by the longitudinal pushing mechanism, and the polishing mechanism can pass through the space between the clamping plate and the wood at this clamping point. In this way, the polishing mechanism can polish the clamping point on the wood, and at this time, other clamping points still clamp the wood, keeping the wood stable during the polishing process. After the polishing of this clamping point is completed, the longitudinal pushing mechanism drives the clamping plate to clamp the wood again. In this way, as the polishing mechanism moves in the first direction, the polishing treatment of each clamping point on the wood is completed in sequence, realizing the polishing treatment of the entire surface of the wood and improving the efficiency of wood polishing.

[0016] 2. By designing the translation mechanism as the cooperation of a base, a lead screw, a translation seat, a driving member, a fixed seat, and a horizontal pushing cylinder, the polishing mechanism can move in the first direction and the second direction, and the second direction is perpendicular to the first direction. In this way, the requirement for the diameter of the polishing wheel is lower, and the polishing effect on the wood is better by the reciprocating movement of the polishing mechanism in the second direction.

[0017] 3. By designing the polishing mechanism as the cooperation of a polishing wheel, a polishing power source, a mounting bracket, and a power transmission mechanism, the structure of the polishing mechanism above the wood is less. The clamping plate only needs to move a short distance to enable the polishing mechanism to pass through the space between the clamping plate and the wood. In this way, the overall volume of the polishing equipment can also be controlled to be smaller.

[0018] 4. By designing the mounting bracket to be vertically slidably connected to the fixed seat and setting the cooperation of the screw rod and the threaded hole to adjust the height of the mounting bracket, the polishing precision of the wood can be adjusted, and the polishing equipment can also be applied to woods of different thicknesses. In addition, the screw rod is rotationally driven by a unidirectional driving mechanism, and the height of the mounting bracket can be adjusted only when the unidirectional driving mechanism applies a rotational force to the screw rod. This can avoid the accidental rotation of the screw rod caused by vibration or other factors during the operation of the polishing mechanism, and improve the stability of the polishing equipment during the polishing process.

[0019] 5. By designing the longitudinal pushing mechanism as the cooperation of a cylinder assembly and a position sensor, the position sensor can detect the distance between the clamping plate and the wood, so that when the thickness of the wood changes before and after polishing, the cylinder assembly can drive the clamping plate to accurately clamp the wood, further improving the stability of the polishing equipment during the polishing process.

[0034] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] In the description of the present application, it should be noted that the terms used herein are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present application. For ease of description, the sizes of the various parts shown in the drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to ordinary technicians in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as merely exemplary, rather than as a limitation. Therefore, other examples of the exemplary embodiments may have different values. It should be noted that similar numbers and letters represent similar items in the following drawings, so once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0036] The polishing equipment recorded in the present invention mainly polishes the two surfaces with larger surface areas of the wood 100. It can be understood that after clamping the two surfaces with larger areas of the wood 100, the side surfaces of the wood 100 are completely exposed, so the side surfaces of the wood 100 can be polished by conventional polishing methods, which will not be repeated here. In the embodiment of the present invention, only the polishing method of the polishing equipment for the two surfaces with larger surface areas of the wood 100, that is, the two clamping surfaces, is described, and the polishing treatment of the two clamping surfaces is performed separately, that is, each polishing treatment is only performed on the upper surface of the wood 100 when it is clamped. When the other surface needs to be polished, the wood 100 needs to be flipped 180 degrees on the vertical plane and then clamped.

[0037] Example 1 like Figures 1-7 As shown, this embodiment provides a wood surface polishing device, including: a fixed frame, a plurality of positioning seats 1, a plurality of clamping plates 2, a longitudinal pushing mechanism, a polishing mechanism 4 and a translation mechanism; See also Figure 1 and Figure 2 In this embodiment, a plurality of positioning seats 1 are arranged on a fixing frame, and a positioning block higher than the positioning seat 1 in the vertical direction Z is arranged on one side of the upper surface of the positioning seat 1 close to the fixing frame, and the wood 100 can be positioned by the positioning block; a plurality of positioning seats 1 are spaced apart in the first direction X, and these positioning seats 1 can contact with the wood 100 at the same time, and the effective number of positioning seats 1 is at least two, and the effective number of positioning seats 1 here can be understood as that the number of positioning seats 1 can be more, but when the wood 100 is placed on the positioning seat 1, the bottom surface of the wood 100 can contact with at least two of the plurality of positioning seats 1; illustratively, three positioning seats 1 are taken as an example in the accompanying drawings; There may also be multiple plywoods 2, each of which is located above a positioning seat 1, and the plywood 2 can approach and move away from the positioning seat 1 in the vertical direction Z. When the wood 100 is placed on the positioning seat 1, the plywood 2 can cooperate with the positioning seat 1 to clamp the wood 100. Each plywood 2 cooperates with a positioning seat 1 to form a clamping point on the wood 100. After the plywood 2 moves away from the positioning seat 1, the polishing mechanism 4 can pass through the space between the plywood 2 and the wood 100 in the first direction X. In this embodiment, at least two plywoods 2 cooperate with at least two positioning seats 1 to form at least two clamping points on the wood 100. By way of example, three plywoods 2 are taken as an example in the accompanying drawings, and the three plywoods 2 cooperate with the three positioning seats 1 to form three clamping points on the wood 100. See also Figure 2 , the longitudinal pushing mechanism can independently drive each clamping plate 2 to approach or move away from the corresponding positioning seat 1. The longitudinal pushing mechanism can be one, which independently drives each clamping plate 2 in a selective driving manner. The longitudinal pushing mechanism can also be multiple, and each clamping plate 2 is independently equipped with a longitudinal pushing mechanism to achieve independent driving of each clamping plate 2. The structures that can achieve the above two driving effects in the prior art can be used as the longitudinal pushing mechanism in this embodiment; See also Figure 3 The polishing mechanism 4 includes a polishing wheel 401 and a polishing power source 402. The end surface of the polishing wheel 401 has a polishing function. The polishing power source 402 can drive the polishing wheel 401 to rotate. The polishing wheel 401 can polish the surface of the wood 100 close to the plywood 2 under the drive of the polishing power source 402. In this embodiment, the polishing wheel 401 can be a product sold on the market, and the polishing power source 402 can be a motor. The translation mechanism can drive the polishing mechanism 4 to move in the first direction X. Any structure in the prior art that can drive the polishing mechanism 4 to move back and forth in a straight line can be used as the translation mechanism in this embodiment. In this embodiment, please refer to Figure 4 , the wood 100 to be polished is placed on multiple positioning seats 1, so that the bottom surface of the wood 100 contacts the multiple positioning seats 1 at the same time, and then the multiple clamping plates 2 are controlled by the longitudinal pushing mechanism to approach the positioning seats 1, and finally the multiple clamping plates 2 cooperate with the multiple positioning seats 1 to clamp the wood 100 at multiple points, and then the translation mechanism is started to move the polishing mechanism 4 from one end of the wood 100 to the other end. In this process, the polishing mechanism 4 polishes the upper surface of the wood 100; please refer to Figure 5 When the polishing mechanism 4 approaches a certain clamping point, the clamping plate 2 at the clamping point moves away from the wood 100 under the control of the longitudinal pushing mechanism. Figure 6 and Figure 7, at this time, the bottom surface of the clamping plate 2 is higher than the top of the polishing mechanism 4, so that the polishing mechanism 4 can pass through the space between the clamping plate 2 at this clamping point and the wood 100, enabling the polishing mechanism 4 to polish the clamping point on the wood 100. And at this time, the wood 100 is also clamped at other clamping points to maintain the stability of the polishing process. After polishing the clamping point, the longitudinal pushing mechanism drives the clamping plate 2 to clamp the wood 100 again. As the polishing mechanism 4 moves in the first direction X, the polishing process is sequentially completed at each clamping point on the wood 100, realizing the polishing of the entire surface of the wood 100 and improving the polishing efficiency of the wood 100.

[0038] Embodiment 2 Based on Embodiment 1, this embodiment also discloses a structure of the translation mechanism. In this embodiment, the translation mechanism includes: a base 501, a lead screw 502, a translation seat 503, and a driving member 504. Please refer to Figure 1 , the base 501 is arranged on one side of the fixed frame, and the base 501 is fixed relative to the positioning seat 1. Specifically, the base 501 has a cross plate and two vertical plates respectively installed at both ends of the cross plate, and the cross plate is located on top of the two vertical plates. Please refer to Figure 2 , the lead screw 502 is rotatably arranged on the base 501 along the first direction X, and the end of the lead screw 502 can be connected to the vertical plate through a bearing. Please refer to Figure 1 , the translation seat 503 is slidably arranged on the cross plate along the first direction X. A nut (not shown in the figure) that is in transmission cooperation with the lead screw 502 is arranged on the translation seat 503. In this embodiment, the polishing mechanism 4 is arranged on the translation seat 503. The driving member 504 can drive the lead screw 502 to rotate. In this embodiment, the driving member 504 can adopt manual driving, such as setting a handwheel at the end of the lead screw 502, or the driving member 504 can also adopt electric control driving, such as connecting a motor to the end of the lead screw 502. Figure 2 The schematic diagrams of setting a handwheel and a motor at both ends of the lead screw 502 are given in , and in actual use, only one can be set according to needs. In this embodiment, after clamping the wood 100, the polishing mechanism 4 is located at one end of the wood 100. Start the polishing power source 402 to drive the polishing wheel 401 to rotate, and then drive the lead screw 502 to rotate through the driving member 504, so that the translation seat 503 drives the polishing mechanism 4 to move towards the other end of the wood 100 in the first direction X to polish the wood 100. The movement of the translation seat 503 is relatively slow. During the movement of the polishing mechanism 4, the worker can observe with the naked eye whether the polishing mechanism 4 has approached the clamping point on the wood 100, so as to pause the movement of the translation seat 503.

[0039] Example 3 On the basis of Example 2, the structure of the translation mechanism is further optimized in this example; In this example, please refer to Figure 1 , a fixed seat 505 is slidably arranged on the translation seat 503 along the second direction Y. A flat push cylinder 506 for driving the fixed seat 505 to move in the second direction Y is arranged on the translation seat 503. The flat push cylinder 506 can be a pneumatic cylinder or a hydraulic cylinder. When in use, the flat push cylinder 506 can be used in combination with a flat driving power source. For example, when the flat push cylinder 506 is a pneumatic cylinder, the pneumatic cylinder is used in combination with the air supply device 306. When the flat push cylinder 506 is a hydraulic cylinder, the hydraulic cylinder is used in combination with the liquid supply device; In this example, the polishing mechanism 4 is arranged on the fixed seat 505. The polishing wheel 401 can be a product with a smaller diameter. When the translation seat 503 moves to a certain position in the first direction X, the translation seat 503 is paused. At this time, the flat push cylinder 506 drives the fixed seat 505 to reciprocate in the second direction Y, so that the polishing wheel 401 reciprocates on the surface of the wood 100 in the second direction Y, and the positions of the wood 100 in the width direction here are polished, so that the polishing effect on the wood 100 is better.

[0040] Example 4 On the basis of Example 3, the structure of the polishing mechanism 4 is further optimized in this example; In this example, the polishing mechanism 4 further includes a mounting frame 507 and a power transmission mechanism 403. Please refer to Figure 3 , the mounting frame 507 is arranged on the fixed seat 505. The first end of the mounting frame 507 extends beyond the fixed seat 505 in the second direction Y. The polishing wheel 401 is rotatably arranged below the first end of the mounting frame 507. The polishing power source 402 is arranged below the second end of the mounting frame 507. The polishing wheel 401 is connected to the polishing power source 402 through the power transmission mechanism 403. The power transmission mechanism 403 can transmit the power output by the polishing power source 402 to the polishing wheel 401; Specifically, the power transmission mechanism 403 includes a first connecting wheel, a second connecting wheel, and a connecting body. The first connecting wheel is disposed above the first end of the mounting bracket 507. The first connecting wheel is coaxially connected to the polishing wheel 401. When the first connecting wheel rotates, it can drive the polishing wheel 401 to rotate. The second connecting wheel is disposed above the second end of the mounting bracket 507. The second connecting wheel is coaxially connected to the output shaft of the polishing power source 402. When the polishing power source 402 is started, its output shaft can drive the second connecting wheel to rotate. The connecting body drives the first connecting wheel and the second connecting wheel to be connected. In this embodiment, the connecting body can be a transmission belt or a transmission chain. That is, the power transmission mechanism 403 in this embodiment can adopt a belt transmission mechanism or a chain transmission mechanism in the prior art. These two transmission methods are well known to those skilled in the art and will not be further described herein; In this embodiment, the power supply structure for the polishing power source 402 can be installed on the fixed seat 505.

[0041] Embodiment 5 Based on Embodiment 4, this embodiment further optimizes the connection method between the polishing mechanism 4 and the translation mechanism; In this embodiment, please refer to Figure 9 , the fixed seat 505 has a vertical section and a horizontal section at the top of the vertical section. The mounting bracket 507 is slidably connected to the vertical section of the fixed seat 505 along the vertical direction Z. A screw rod 6 is disposed on the fixed seat 505 along the vertical direction Z. A threaded hole 601 is disposed on the horizontal section of the fixed seat 505. The threaded end of the screw rod 6 is rotatably connected to the mounting bracket 507. The screw rod 6 is threadedly connected to the threaded hole 601. A one-way driving mechanism 7 for driving the screw rod 6 to rotate is disposed on the fixed seat 505. The one-way driving mechanism 7 can limit the active rotation of the screw rod 6; By driving the screw rod 6 to rotate through the one-way driving mechanism 7, the vertical position of the mounting bracket 507 on the fixed seat 505 can be adjusted, so as to adjust the vertical distance between the polishing mechanism 4 and the wood 100. In this way, the polishing accuracy of the wood 100 can be adjusted, and the polishing equipment can also be applied to woods 100 of different thicknesses; when adjusting the position of the polishing mechanism 4, it can be used in conjunction with external measuring tools such as a scale; In this embodiment, an additional auxiliary support structure that can expand and contract as the position of the mounting bracket 507 moves can also be disposed between the mounting bracket 507 and the fixed seat 505 to ensure the structural stability of the mounting bracket 507. For example, a guide sleeve is disposed on the fixed seat 505, a guide post is disposed on the mounting bracket 507, the guide post is slidably inserted into the guide sleeve along the vertical direction Z, and a locking structure is disposed between the guide sleeve and the guide post. The locking structure can lock the guide post in the guide sleeve after the position of the mounting bracket 507 is adjusted. When the vertical position of the mounting bracket 507 needs to be adjusted, the guide post and the guide sleeve are unlocked; such auxiliary support structures are relatively common in the art and will not be further described herein; The one-way drive mechanism 7 can limit the active rotation of the screw rod 6, so that the screw rod 6 can only be driven to rotate through the one-way drive mechanism 7, and the screw rod 6 cannot actively rotate to drive the one-way drive mechanism 7 to move. This can avoid the accidental rotation of the screw rod 6 caused by vibration or other factors during the operation of the polishing mechanism 4, and improve the stability of the polishing equipment during the polishing process.

[0042] In this embodiment, please refer to Figure 9 , the one-way drive mechanism 7 includes: a fixed gear ring 701, a connecting column 702 and a driving block 704; Please refer to Figure 9 and Figure 10 , the fixed gear ring 701 is integrally in a ring structure. Fixed teeth are distributed along the circumferential direction on the inner wall of the fixed gear ring 701. The fixed gear ring 701 is fixedly installed on the horizontal section of the fixed seat 505, so that the position of the fixed gear ring 701 relative to the fixed seat 505 is fixed, and the fixed gear ring 701 and the screw rod 6 are coaxially distributed; The connecting column 702 is arranged inside the fixed gear ring 701. Please refer to Figure 10 , the length of the connecting column 702 in the vertical direction Z is less than the length of the fixed gear ring 701 in the vertical direction Z. The end of the screw rod 6 far from the mounting frame 507 is a fixed end. The contour of the fixed end of the screw rod 6 is a regular polygon. A transmission groove 703 adapted to the fixed end of the screw rod 6 is arranged in the middle of the bottom surface of the connecting column 702, and the contour of the transmission groove 703 is also a regular polygon. Figure 10 Taking a regular hexagon as an example in Please refer to Figure 10 and Figure 11, an installation block 7031 is installed on the side wall of the connecting column 702. The installation block 7031 does not contact the fixed teeth in the radial direction of the fixed tooth ring 701. Two connecting arms 7032 are symmetrically arranged on both sides of the installation block 7031. The connecting arms 7032 extend along the circumferential direction of the connecting column 702. There is a spacing between the connecting arms 7032 and the side wall of the connecting column 702. The connecting arms 7032 are elastic. A contact block 7033 is arranged at one end of the connecting arm 7032 away from the installation block 7031. When the contact block 7033 is squeezed towards the axis direction of the connecting column 702, the connecting arm 7032 can be deformed. When the contact block 7033 is squeezed towards the circumferential direction of the connecting column 702, the connecting arm 7032 will not be deformed; the surface of the side of the contact block 7033 away from the installation block 7031 contacts the surface of the fixed tooth, and the surface of the side of the contact block 7033 close to the installation block 7031 contacts the tooth tip of the fixed tooth; Take Figure 11 the contact block 7033 at the lower left in the figure as an example. Temporarily regard the other contact blocks 7033 as hidden. At this time, the surface of the side of the contact block 7033 away from the installation block 7031 contacts the surface of the fixed tooth. When the connecting column 702 has a tendency to rotate counterclockwise at this time, the surface of the side of the contact block 7033 away from the installation block 7031 abuts against the surface of the fixed tooth, restricting the rotation of the connecting column 702; when the connecting column 702 has a tendency to rotate clockwise at this time, the surface of the side of the contact block 7033 close to the installation block 7031 will be squeezed by the tooth tip of the fixed tooth, so that the whole contact block 7033 is squeezed towards the axis direction of the connecting column 702. In this way, the connecting arm 7032 is deformed, causing the surface of the side of the contact block 7033 away from the installation block 7031 to separate from the surface of the fixed tooth. At this time, the rotation of the connecting column 702 is allowed; therefore, after the connecting arms 7032 and the contact blocks 7033 are arranged on both sides of the installation block 7031, the rotation actively initiated by the connecting column 702 can be restricted, and the screw 6 is coaxially driven to connect with the connecting column 702, that is, the active rotation of the screw 6 is restricted; Please refer to Figure 9 or Figure 10 , a driving block 704 is arranged on the side of the connecting column 702 away from the screw 6. The driving block 704 is coaxially distributed with the connecting column 702. An arc-shaped block 7041 is arranged on the driving block 704. The inner wall and the outer wall of the arc-shaped block 7041 are both arc-shaped. The arc-shaped block 7041 can extend into the space between the installation block 7031 and the fixed teeth. Please refer to Figure 11 and Figure 12, the arc-shaped block 7041 will not contact the fixed teeth. When the driving block 704 rotates circumferentially, it can drive the arc-shaped block 7041 to contact the contact block 7033. The surface where the arc-shaped block 7041 contacts the contact block 7033 is an inclined surface, so that the contact block 7033 is located on the movement path of the arc-shaped block 7041. In this way, the arc-shaped block 7041 can squeeze the contact block 7033 and push the connecting arm 7032 towards the side wall of the connecting column 702, separating the side of the contact block 7033 away from the mounting block 7031 from the surface of the fixed teeth. The distance between the connecting arm 7032 and the connecting column 702 is limited. Please refer to Figure 12 , to Figure 12 , taking the contact block 7033 at the lower left in Figure 12 as an example, when the driving block 704 rotates counterclockwise, after the contact block 7033 contacts the outer wall of the connecting column 702, the position of the contact block 7033 will not move further. At this time, the arc-shaped block 7041 can still contact the surface of the contact block 7033. In this way, the arc-shaped block 7041 can push the contact block 7033, the connecting arm 7032 and the mounting block 7031 to move counterclockwise, while , the contact block 7033 at the upper left in Figure 12 can follow the movement of the mounting block 7031. When the contact block 7033 moves counterclockwise, it will drive the connecting column 702 to move counterclockwise, thereby driving the screw 6 to rotate counterclockwise; Figure 12 Through the above description, it can be understood that when the driving block 704 rotates clockwise, taking the contact block 7033 on the left side in as an example, the arc-shaped block 7041 can squeeze and push the contact block 7033 on the upper left side in to move clockwise, thereby driving the screw 6 to rotate clockwise. In this way, the rotation of the connecting column 702 and the screw 6 is driven by the driving block 704;

One end of the two pipes 303 is respectively connected to the two pressure chambers. The ends of the two pipes 303 away from the cylinder block 301 are connected to a gas supply device 306. The gas supply device 306 can supply gas to the pressure chambers through the pipes 303. By the pressure change in the two pressure chambers, the piston 302 is driven to move in the chamber. The solenoid valve 304 can control the conduction and cut-off of the pipe 303. A connecting rod is arranged outside the cylinder block 301. One end of the connecting rod passes through the cylinder block 301 and is connected to the piston 302, and the other end of the connecting rod is connected to the clamping plate 2.

During the process of the cylinder assembly 3 driving the clamping plate 2 to approach the positioning seat 1 or the wood 100, the position sensor 9 monitors the distance between the bottom surface of the clamping plate 2 and the positioning seat 1 or the wood 100 in real time and can transmit the signal to the controller 305. The controller 305 can store a preset value and compare the signal value transmitted by the position sensor 9 with the preset value, so as to control the working state of the two solenoid valves 304. When the clamping plate 2 does not reach the preset position (that is, when it does not press the positioning seat 1 or the wood 100), the controller 305 controls the two solenoid valves 304 to conduct the pipes 303, and the gas supply device 306 passes through Figure 8The pipeline 303 on the upper middle side fills the pressure chamber above the piston 302 with gas, causing the piston 302 to move downward. During this process, the gas in the pressure chamber below the piston 302 can be discharged from the pressure chamber through the corresponding pipeline 303, enabling the clamping plate 2 to continue approaching the positioning seat 1 or the wood 100; when the clamping plate 2 presses against the positioning seat 1 or the wood 100, the controller 305 controls both solenoid valves 304 to cut off the pipeline 303, so that the pressure values in the two pressure chambers do not change, thereby stabilizing the piston 302 at the current position and ensuring the stable clamping of the clamping plate 2; In this embodiment, the controller 305 can be a PLC or a single-chip microcomputer, and the gas supply device 306 can be a product such as an air compressor.
