Description

Technical Field

[0001] The invention relates to the technical field of punching equipment, and in particular discloses an anti-deviating mechanism for decorative and finishing punching equipment. Background Art

[0002] During the decoration process, the important material for making cabinets, tables and chairs is boards. In order to ensure the connection between the boards, it is necessary to use punching equipment to punch holes in the boards. When punching the boards, in order to ensure that their position does not shift, it is necessary to use a clamping mechanism (anti-shift mechanism) to limit the position of the boards.

[0003] For example, the patent with announcement number CN117001034B, with announcement date of January 9, 2024, discloses a CNC device for punching holes in furniture panels, which relates to the technical field of furniture CNC processing equipment. The device comprises a base, a drilling mechanism fixedly connected to the top of the base, a material pushing mechanism located below the drilling mechanism fixedly connected to the top of the base, and a fixing seat, an air chamber, a piston, a pull rod, a suction cup, a connecting rod, and a return spring. The present invention pushes the rack to slide downward during the descent of the crossbeam, thereby causing the connecting rod to drive the pull rod to slide downward, and causing the connecting rod to compress the return spring, thereby driving the piston to slide downward inside the air chamber, generating negative pressure inside the air chamber, thereby causing the suction cup to absorb and fix the upper panel. During the reset of the rack, the return spring rebounds and pushes the connecting rod to reset, causing the connecting rod to reset the piston through the connecting rod, thereby causing the piston to push the air inside the air chamber between the suction cup and the panel, thereby automatically contacting the panel to limit the position, thereby improving the efficiency of panel processing.

[0004] The disadvantage of the anti-deviating mechanism of the existing punching equipment, including the above-mentioned patent, is that the existing decorative panels are mostly fixed by the four sides of the panels during processing, and the drilling position is not subject to any limit. When the thickness of the panels to be drilled is relatively small, the withdrawal of the drill will cause the panels to deform upward. For thicker composite panels (laminated panels and composite panels), the part near the hole is easily affected by the cutting force during drilling, resulting in tearing or burrs on the hole wall. Summary of the Invention

[0005] The purpose of the present invention is to provide an anti-deviating mechanism for decorative and finishing punching equipment.

[0006] In order to achieve the above object, the present invention provides the following technical solutions: Disclosed is an anti-deviation mechanism for decorative and finishing punching equipment, which is used to prevent deflection when punching holes in flat plates. The mechanism comprises a mounting seat on which a drilling assembly is mounted, and an extrusion piece movably mounted on the mounting seat. The extrusion piece is provided with a clearance hole for the drill bit of the drilling assembly to pass through, and the extrusion piece is driven to squeeze the drilling position on the plate.

[0007] The anti-deviating mechanism comprises an extrusion member including a cylindrical extrusion cylinder which is sleeved on the outside of the drill bit, the lower part of the inner cavity of the extrusion cylinder is funnel-shaped, and the extrusion cylinder is slidably mounted on the mounting seat.

[0008] The anti-deviating mechanism is provided with an elastic member on the mounting seat for maintaining the relative positions of the extrusion cylinder and the mounting seat. The elastic member is deformed by extrusion to enable the extrusion cylinder and the drill bit to move relative to each other.

[0009] The above-mentioned anti-deviance mechanism has a piston cylinder fixedly connected to the inner wall of the extrusion cylinder, and a piston block is slidably installed in the piston cylinder. After the mounting seat is driven downward until the extrusion cylinder contacts the plate, the drilling assembly moves downward relative to the extrusion cylinder. At the same time, the drilling assembly drives the piston block to move in the piston cylinder and discharge the gas in the piston cylinder to the outside.

[0010] The above-mentioned anti-deviation mechanism, the drilling assembly includes a shell and a drill bit rotatably installed at the lower part of the shell, the outer wall of the shell is fixedly connected to an extrusion block that cooperates with the push rod, the upper end of the push rod is fixedly connected to an adjustment block, and the adjustment block extends to the bottom of the extrusion block.

[0011] The anti-deviating mechanism has a second spring sleeved on the push rod. When the second spring is in a natural state, the piston block is at the uppermost end inside the piston cylinder.

[0012] The anti-deviating mechanism has a mounting seat slidably connected to a fixing seat, and the extrusion cylinder includes two groups of extrusion parts that are in contact with each other and symmetrically arranged, and the two extrusion parts are driven to separate.

[0013] The two extrusion parts of the anti-deviating mechanism are both rotatably mounted on the lower surface of the fixing seat.

[0014] The above-mentioned anti-deviance mechanism is that the mounting seat is movably mounted on the movable seat, the inner walls of the two extrusion parts are provided with adjustment parts, and the middle part of the movable seat is provided with a baffle for limiting the height of the fixed seat. When the mounting seat is driven to move upward until the fixed seat contacts the baffle and continues to move upward, the two adjustment parts respectively drive their corresponding extrusion parts to rotate.

[0015] In the above-mentioned anti-deviation mechanism, a first torsion spring is provided on the rotating shaft of the two extrusion parts. The two first torsion springs are respectively used to maintain their corresponding extrusion parts in a vertical state. The adjusting part includes an extrusion rod installed on the inner wall of the extrusion part. When the drilling assembly moves upward relative to the fixed seat, the extrusion rod is driven to push its corresponding extrusion part to rotate.

[0016] In the above technical solution, the anti-deviation mechanism provided by the present invention is provided with an extrusion part and a clearance hole for the drill bit to pass through is opened on the extrusion part. When drilling, the drilling position on the plate is pressed by the extrusion part, leaving only a position the size of the clearance hole for drilling. The plate is directly pressed and limited by the periphery of the drilling position on the plate, and the limiting effect is good. The plate is not easily torn due to the restriction of the extrusion part. When the processed plate is a laminated plate, it can also prevent interlayer peeling. After the plate is punched, the extrusion part blocks the plate, which can also prevent the thinner plate from being pulled upward and deformed by the drill bit, thereby facilitating the separation of the drill bit from the plate.

[0020] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms “connected” and “connected” should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0022] like Figure 1-Figure 7 As shown, an embodiment of the present invention provides an anti-deviation mechanism for decorative and finishing punching equipment, which is used to prevent deflection when punching holes in flat plates, including a mounting base 1, on which a drilling assembly 2 is mounted, and an extrusion member 3 is movably mounted on the mounting base 1, and the extrusion member 3 is provided with a clearance hole 32 for the drill bit 22 of the drilling assembly 2 to pass through, and the extrusion member 3 is driven to squeeze the drilling position on the plate.

[0023] Specifically, the anti-deviation mechanism is used to press the outer side of the plate at the drilling position, which includes a mounting seat 1, and the punching equipment includes a workbench and an adjusting frame installed on the workbench. The mounting seat 1 is movably installed on the adjusting frame, and the adjusting frame is provided with a lateral adjustment mechanism 7 for driving the mounting seat 1 to move horizontally, and a longitudinal adjustment mechanism 8 for driving the mounting seat 1 to move vertically; the drilling assembly 2 of the punching equipment is installed on the mounting seat 1, and the mounting seat 1 is also movably provided with an extrusion member 3. Optionally, the extrusion member 3 includes a linear drive mechanism such as a cylinder fixedly mounted on the mounting seat 1, and a horizontally arranged pressure plate installed at the output end of the cylinder. The cylinder is vertically fixed on the mounting seat 1, and the pressure plate is fixedly connected to the output end of the cylinder, so that the extension of the cylinder can drive the pressure plate to move vertically downward relative to the mounting seat 1. The middle part of the pressure plate is provided with a clearance hole 32 for the drill bit 22 to pass through, and the diameter of the clearance hole 32 is larger than the drill bit. The diameter of the head 22, preferably, the diameter of the clearance hole 32 is 0.5cm to 1cm larger than the drill bit 22, which can prevent the drill bit 22 and the pressure plate from contacting each other, and can also be used to discharge the debris generated during drilling. Obviously, in order to avoid damage to the workbench and the drill bit 22, a small hole is provided on the workbench to avoid the drill bit 22, so as to ensure that the drill bit 22 can extend into the small hole when drilling through the plate without direct contact with the workbench. Preferably, the small hole on the workbench is the same size as the clearance hole 32 on the pressure plate. In addition, the workbench is also provided with a limiting structure for clamping and limiting the plate (not shown in the figure). The limiting structure limits the plate from all sides of the plate, and cooperates with the extrusion limiting member to further enhance the limiting effect of the plate. The limiting structure is an existing clamping member. It is an existing technology to limit the plate on the workbench and prevent it from moving by the clamping member. It can be directly applied and will not be elaborated on.

[0024] When punching a hole in a plate, the plate is initially restricted on the workbench by a limiting structure provided on the workbench. Then, the lateral adjustment mechanism 7 drives the mounting base 1 to move horizontally to the top of the punching position. Then, the longitudinal adjustment mechanism 8 drives the mounting base 1 to move down a certain distance to reduce the distance between the drill bit 22 and the pressing plate and the plate. The cylinder extends and drives the pressing plate to move vertically downward until it contacts the plate surface and squeezes the plate tightly against the working platform of the punching equipment. The drilling machine is started and the mounting base 1 is driven to move vertically downward. At the same time, the cylinder is in contact with the mounting base 1. The seat 1 is shortened at the same speed when it moves downward, ensuring that the pressure plate limits the extrusion of the plate while allowing the drill bit 22 to move relative to the pressure plate until the drill bit 22 passes through the clearance hole 32 on the pressure plate and completely drills through the plate. After drilling is completed, the mounting seat 1 is driven upward by the longitudinal adjustment mechanism 8. During this process, the cylinder extends at the same speed as the mounting seat 1 moves upward, ensuring that the pressure plate can still maintain the extrusion of the plate. After the drill bit 22 moves completely to the top of the plate, the longitudinal adjustment mechanism 8 is temporarily paused, the cylinder shortens and drives the pressure plate upward.

[0025] The anti-deviation mechanism provided by the embodiment of the present invention is provided with an extrusion part 3 and a clearance hole 32 for the drill bit 22 to pass through the extrusion part 3. When drilling, the drilling position on the plate is pressed by the extrusion part 3, leaving only a position the size of the clearance hole 32 for drilling. The plate is directly pressed and limited by the periphery of the drilling position on the plate, and the limiting effect is good. The plate is not easily torn due to the restriction of the extrusion part 3. When the processed plate is a laminated plate, it can also prevent interlayer peeling. After the plate is punched, the extrusion part 3 blocks the plate, which can also prevent the thinner plate from being pulled upward and deformed by the drill bit 22, making it easier for the drill bit 22 to separate from the plate.

[0026] Furthermore, the extrusion member 3 includes a cylindrical extrusion cylinder 31 , which is sleeved on the outside of the drill bit 22 . The lower part of the inner cavity of the extrusion cylinder 31 is funnel-shaped, and the extrusion cylinder 31 is slidably mounted on the mounting seat 1 .

[0027] Specifically, during the actual drilling process, the splashing of wood chips and the diffusion of dust pose a great threat to the health of workers. In this embodiment, the extrusion member 3 includes an extrusion cylinder 31, which is cylindrical and has a cavity inside. The extrusion cylinder 31 is mounted on the outside of the drill bit 22, and the lower part of the inner cavity of the extrusion cylinder 31 is funnel-shaped, so that the wood chips and dust generated during drilling can be guided upward by the drill bit 22. In this embodiment, the extrusion cylinder 31 is directly slidably installed on the mounting base 1, and the output end of the above-mentioned cylinder is fixedly connected to the extrusion cylinder 31. With this arrangement, the wood chips and dust generated during drilling will be blocked by the extrusion cylinder 31, thereby avoiding the splashing of wood chips and the diffusion of dust.

[0028] Furthermore, an elastic member is provided on the mounting base 1 to maintain the relative positions of the extrusion cylinder 31 and the mounting base 1 . The elastic member is deformed by extrusion to enable the extrusion cylinder 31 and the drill bit 22 to move relative to each other.

[0029] Specifically, in the above embodiment, the cylinder is used to drive the extrusion cylinder 31, and the longitudinal adjustment mechanism 8 is used to drive the mounting seat 1 to move in the vertical direction, so that the extrusion of the plate can be maintained during the drilling process. This has high requirements for the extension and contraction speed of the cylinder and the speed of the longitudinal adjustment mechanism 8 to drive the mounting seat 1 to move downward. Careless operation may easily cause damage to the cylinder and the connection position between the extrusion cylinder 31 and the mounting seat 1; in this embodiment, an elastic member is provided on the mounting seat 1 to maintain the relative position of the extrusion cylinder 31 and the mounting seat 1, and the elastic member includes a guide rod 11 connected to the extrusion cylinder 31, and the guide rod 11 is provided with a first spring 12, and the mounting seat 1 is provided with a spring for cooperating with the guide rod 11 The guide block 13 of the guide rod 11 passes through the guide block 13; with such a configuration, when the longitudinal adjustment mechanism 8 drives the mounting seat 1 to move downward, the extrusion cylinder 31 can move downward synchronously with the drill bit 22, and when the extrusion cylinder 31 contacts the surface of the plate, the downward movement of the extrusion cylinder 31 is restricted. At this time, the extrusion cylinder 31 slides upward on the mounting seat 1 and squeezes the first spring 12 to deform; and in the process of the mounting seat 1 being driven to move upward, the reset of the first spring 12 can push the extrusion cylinder 31 to slide downward on the mounting seat 1, so as to keep the extrusion cylinder 31 in contact with the plate, thereby preventing the plate from being pulled upward and deformed by the drill bit 22. After the first spring 12 is completely reset, the mounting seat 1 can drive the extrusion cylinder 31 to move upward synchronously.

[0030] In another embodiment proposed by the present invention, the inner wall of the extrusion cylinder 31 is fixedly connected to the piston cylinder 4, and a piston block 41 is slidably installed in the piston cylinder 4. After the mounting seat 1 is driven to move downward until the extrusion cylinder 31 contacts the plate, the drilling assembly 2 moves downward relative to the extrusion cylinder 31. At the same time, the drilling assembly 2 drives the piston block 41 to move in the piston cylinder 4 and discharge the gas in the piston cylinder 4 to the outside.

[0031] Furthermore, the drilling assembly 2 includes a shell 21 and a drill bit 22 rotatably mounted on the lower part of the shell 21. The outer wall of the shell 21 is fixedly connected to an extrusion block 23 that cooperates with the push rod 42. The upper end of the push rod 42 is fixedly connected to an adjustment block 43, which extends to the bottom of the extrusion block 23.

[0032] Specifically, in the above embodiment, the relative positions of the extrusion cylinder 31 and the drill bit 22 are limited by the elastic member, ensuring that the extrusion cylinder 31 squeezes the plate while the drill bit 22 can move downward to drill. However, due to the characteristics of the elastic member itself, in the early stage of drilling, the relative displacement of the extrusion cylinder 31 and the drill bit 22 is small, so that the force exerted by the elastic member on the extrusion cylinder 31 is small, resulting in the extrusion cylinder 31 being insufficient to tightly press the plate. In this embodiment, the inner wall of the extrusion cylinder 31 is fixedly connected to the piston cylinder 4, such as Figures 4 to 6As shown, the piston cylinder 4 is arranged vertically, and a piston block 41 is slidably installed in the inner cavity of the piston cylinder 4, and a push rod 42 is fixed to the upper surface of the piston block 41, and the upper end of the push rod 42 passes through the outside of the piston cylinder 4, and an air inlet 401 and an air outlet 402 are provided at the lower part of the piston cylinder 4, wherein the diameter of the air inlet 401 is larger than the diameter of the air outlet 402, and a one-way valve 403 is installed at the air inlet 401 and the air outlet 402, the outlet end of the one-way valve 403 at the air inlet 401 faces the inside of the piston cylinder 4, and the air inlet end of the one-way valve 403 at the air outlet 402 faces the inside of the piston cylinder 4, by providing the air outlet 402 with a smaller aperture, the speed at which the air in the piston cylinder 4 is discharged outwards when the piston block 41 moves is limited, ensuring that when the mounting seat 1 is driven to move downward, it can provide sufficient pressure to enable the extrusion cylinder 31 to press the plate , and the provision of an air inlet 401 with a larger aperture can reduce the resistance of the piston block 41 when it moves in the opposite direction (moving from the lower part to the upper part of the piston cylinder 4), thereby facilitating the upward movement and reset of the piston block 41; the drilling assembly 2 includes a shell 21 and a drill bit 22 rotatably mounted on the lower part of the shell 21, and a motor (not shown in the figure) is provided in the shell 21 for driving the drill bit 22 to rotate, an extrusion block 23 is fixedly connected to the outer wall of the shell 21, and an adjustment block 43 is fixedly connected to the upper end of the push rod 42, and the adjustment block 43 extends horizontally to the bottom of the extrusion block 23; preferably, the air inlet 401 passes through the side wall of the first extrusion part 311 or the second extrusion part 312 and communicates with the outside, thereby preventing dust or wood chips in the extrusion cylinder 31 from being sucked into the piston cylinder 4, and the air outlet 402 is communicated with the internal space of the first extrusion part 311 or the second extrusion part 312.

[0033] With such arrangement, in the initial stage when the mounting seat 1 is driven to move downward, the extrusion cylinder 31, maintained by the above-mentioned elastic member, keeps moving downward synchronously with the shell 21 until the extrusion cylinder 31 contacts the surface of the plate. The extrusion cylinder 31 is blocked by the plate and cannot continue to move downward, and it will slide upward on the mounting seat 1. At this time, the extrusion block 23 arranged on the outside of the shell 21 contacts the adjustment block 43, and pushes the piston block 41 to move downward in the piston cylinder 4 through the adjustment block 43 and the push rod 42, and discharges the air in the piston cylinder 4 to the outside through the air outlet. In this process, since the discharge speed of the air in the piston cylinder 4 is limited, the air pressure in the lower part of the piston cylinder 4 gradually increases, and the piston block 41 will encounter upward resistance when moving downward. Similarly, the piston cylinder 4 will also be subjected to a downward force, and the extrusion cylinder 31 is restricted by the plate and cannot move. Under the action of the downward force exerted on the piston cylinder 4, the extrusion cylinder 31 can be tightly pressed against the surface of the plate.

[0034] In this embodiment, a piston cylinder 4 is provided on the inner wall of the extrusion cylinder 31, and a piston block 41 is provided in the piston cylinder 4, and a small-aperture air outlet 402 is opened in the lower part of the piston cylinder 4. When the shell 21 moves downward to push the piston block 41 to move downward in the piston cylinder 4, the extrusion cylinder 31 can be subjected to a downward force by limiting the downward movement speed of the piston block 41, thereby ensuring that the extrusion cylinder 31 can be tightly pressed against the plate at the initial stage of drilling; on the other hand, at the moment when the drill bit 22 penetrates the plate, the obstruction of the movement of the piston block 41 in the piston cylinder 4 can also buffer the shell 21, thereby preventing the shell 21 and its internal structure from being damaged due to inertia.

[0035] Furthermore, a second spring 421 is sleeved on the push rod 42 . When the second spring 421 is in a natural state, the piston block 41 is at the uppermost end inside the piston cylinder 4 .

[0036] Specifically, in order to ensure that the piston block 41 can automatically move up to the upper part of the piston cylinder 4 when the push rod 42 is not squeezed, a second spring 421 is installed on the push rod 42. The upper end of the second spring 421 contacts the above-mentioned adjustment block 43, and the lower end of the second spring 421 contacts the upper surface of the piston cylinder 4. Figures 4 to 6 As shown, when the second spring 421 is in a natural state, the length of the push rod 42 extending out of the piston cylinder 4 is the largest, so that when the push rod 42 is not squeezed, the piston block 41 can remain at the uppermost part in the piston cylinder 4.

[0037] In another embodiment of the present invention, a fixing seat 33 is slidably connected to the mounting seat 1 , and the extrusion cylinder 31 includes two groups of extrusion parts that are in contact with each other and symmetrically arranged, and the two extrusion parts are driven to separate.

[0038] Specifically, due to the small diameter of the clearance hole 32 opened on the extrusion cylinder 31, the wood chips and dust generated during drilling cannot be completely discharged through the clearance hole 32, and the wood chips and dust are retained in the extrusion cylinder 31, which will affect the rotation and heat dissipation of the drill bit 22, and the strip-shaped wood chips will also be entangled with the outside of the drill bit 22; in this embodiment, a fixing seat 33 is slidably installed on the mounting seat 1, such as Figure 3 As shown, the fixing seat 33 is sleeved on the outside of the shell 21, and the extrusion cylinder 31 includes two symmetrically arranged extrusion parts, one of which is Figures 4 to 6The left side is the first extrusion part 311, and the right side is the second extrusion part 312. The first extrusion part 311 and the second extrusion part 312 have the same structure and are both semi-cylindrical. When the two are in contact with each other, they can form the above-mentioned extrusion cylinder 31, and the clearance hole 32 in this embodiment is also divided into two semi-circular holes. When the first extrusion part 311 and the second extrusion part 312 are in contact, the clearance hole 32 can be formed. In this embodiment, the first extrusion part 311 and the second extrusion part 312 can be slidably installed on the fixing seat 33, and the first extrusion part 311 and the second extrusion part 312 are both It can slide horizontally on the fixed seat 33, and the sliding directions of the two are opposite, and a linear drive mechanism (not shown in the figure) is provided on the fixed seat 33 to drive the first extrusion part 311 and the second extrusion part 312 away from each other. After the drilling is completed, the first extrusion part 311 and the second extrusion part 312 are driven horizontally and in opposite directions by the linear drive mechanism to pour out the wood chips and dust inside them. Different from the above embodiment, in this embodiment, the guide rod 11 of the above-mentioned elastic member is fixedly connected to the fixed seat 33, so that the elastic member can simultaneously maintain the relative positions of the two extrusion parts and the mounting seat 1.

[0039] Furthermore, the first extrusion portion 311 and the second extrusion portion 312 are both rotatably mounted on the lower surface of the fixing seat 33 .

[0040] Specifically, in order to prevent wood chips from gathering near the drill bit 22, the inner diameter of the extrusion cylinder 31 needs to be much larger than the diameter of the drill bit 22, and the slope of the lower part of the inner cavity of the extrusion cylinder 31 needs to be as small as possible, so that the centrifugal force generated by the rotation of the drill bit 22 can be used to keep the wood chips away from the surface of the drill bit 22. This results in the wood chips not being able to be smoothly poured out by horizontally moving the first extrusion part 311 and the second extrusion part 312 to the sides, and some wood chips will still be retained on the inclined inner wall of the lower part of the extrusion cylinder 31; in this embodiment, the first extrusion part 311 and the second extrusion part 312 are both rotatably mounted on the lower surface of the fixing seat 33, as shown in FIG. Figures 4 to 6 As shown, what is different from the above embodiment is that a rotating driving member (not shown in the figure) is provided on the fixing seat 33 to drive the first extrusion part 311 and the second extrusion part 312 to rotate. For example, motors are respectively provided corresponding to the first extrusion part 311 and the second extrusion part 312, and the output ends of the two motors are respectively connected to the rotating shafts of the first extrusion part 311 and the second extrusion part 312. This is the existing technology and will not be repeated.

[0041] In another embodiment proposed by the present invention, the mounting seat 1 is movably mounted on the movable seat 5, the inner walls of the two extrusion parts are provided with adjustment parts, and the middle part of the movable seat 5 is provided with a baffle 51 for limiting the height of the fixed seat 33. When the mounting seat 1 is driven to move upward until the fixed seat 33 contacts the baffle 51 and continues to move upward, the two adjustment parts respectively drive the corresponding extrusion parts to rotate.

[0042] Furthermore, a first torsion spring (not shown in the figure) is provided on the rotating shaft of the two extrusion parts. The two first torsion springs are respectively used to maintain their corresponding extrusion parts in a vertical state. The adjusting part includes an extrusion rod 6 rotatably installed on the inner wall of the extrusion part. When the drilling assembly 2 moves upward relative to the fixed seat 33, the extrusion rod 6 is driven to push its corresponding extrusion part to rotate.

[0043] Specifically, the output end of the above-mentioned lateral adjustment mechanism 7 is equipped with a moving seat 5, the lateral adjustment mechanism 7 is used to drive the moving seat 5 to move horizontally, and the mounting seat 1 is movably installed on the moving seat 5, and the above-mentioned longitudinal adjustment mechanism 8 is installed on the moving seat 5, and can drive the mounting seat 1 to move vertically on the moving seat 5. In this embodiment, the inner walls of the first extrusion portion 311 and the second extrusion portion 312 are both provided with adjustment members, and in this embodiment, when the elastic member is in a natural state, the fixed seat 33 is in the middle of the mounting seat 1, that is, when the fixed seat 33 is in this position, it can slide toward the upper part of the mounting seat 1, and can slide toward the lower part of the mounting seat 1. Optionally, the upper end of the first spring 12 is fixedly connected to the above-mentioned guide block 13, and the lower end of the first spring 12 is fixedly connected to the upper surface of the fixed seat 33. When the first spring 12 is in a natural state (in this state, it is not the original length of the first spring 12. At this time, the first spring 12 is in a preliminary stretched state under the action of the gravity of the fixed seat 33 and the two extrusion portions); as shown in FIG. Figures 3 to 6 As shown, a baffle 51 is provided in the middle of the movable seat 5, the baffle 51 is fixedly connected to the movable seat 5, and the end of the baffle 51 away from the movable seat 5 is bent to directly above the fixed seat 33, and the first extrusion part 311 and the second extrusion part 312 are both provided with a first torsion spring at the position where they are rotatably connected to the fixed seat 33, and the two first torsion springs respectively maintain the first extrusion part 311 and the second extrusion part 312 in a vertical state. When in this state, the first extrusion part 311 and the second extrusion part 312 are completely in contact to form the above-mentioned extrusion cylinder 31, in addition, the upper inner walls of the first extrusion part 311 and the second extrusion part 312 are both rotatably connected to the extrusion rod 6, and a second torsion spring (not shown in the figure) is provided at the rotating axis where the extrusion rod 6 is rotatably connected to the first extrusion part 311 or the second extrusion part 312. When the second torsion spring is in a natural state, the end of the extrusion rod 6 away from the first extrusion part 311 or the second extrusion part 312 is directly above the extrusion block 23, as shown in FIG. Figure 5 and Figure 6 shown.

[0044] In this embodiment, the fixing base 33 has a first position, a second position and a third position relative to the mounting base 1: When in the first position, the fixing seat 33 is in the middle of the mounting seat 1. In this state, the first extrusion portion 311 and the second extrusion portion 312 are kept in contact with each other under the maintenance of the first torsion spring. Figure 4 As shown; In the second position, which is the late stage of drilling, that is, when the drill bit 22 completely penetrates the plate, the fixing seat 33 is located on the mounting seat 1, and the fixing seat 33 is located in the upper middle part of the mounting seat 1. In this state, the first extrusion portion 311 and the second extrusion portion 312 are still in contact, and the extrusion rod 6 is not in contact with the extrusion block 23, but the extrusion block 23 is in contact with the adjustment block 43. Figure 5 shown.

[0045] When in the third position, the fixing seat 33 is at the lowest part on the mounting seat 1. In this state, the extrusion rod 6 contacts the extrusion block 23 and rotates to the state with the smallest angle with the horizontal direction under the push of the extrusion block 23 (the end of the extrusion rod 6 connected to the first extrusion part 311 or the second extrusion part 312 needs to be always higher than the extrusion block 23, otherwise it cannot push the first extrusion part 311 and the second extrusion part 312 to rotate). At this time, the first extrusion part 311 and the second extrusion part 312 are rotated to the open state under the push of the extrusion rod 6, that is, at this time, the angle between the first extrusion part 311 and the second extrusion part 312 is the largest. Figure 6 shown.

[0046] When the longitudinal adjustment mechanism 8 drives the mounting base 1 to move downward on the movable base 5, the mounting base 1 first drives the first extruding portion 311, the second extruding portion 312 and the shell 21 to move downward synchronously. During this process, the first extruding portion 311 and the second extruding portion 312 remain in contact with each other under the restriction of the first torsion spring, that is, the lower surfaces of the first extruding portion 311 and the second extruding portion 312 are in a horizontal state, and the fixed base 33 remains in the first position on the mounting base 1. When the first extruding portion 311 and the second extruding portion 312 contact the surface of the plate, they are blocked and slide upward on the mounting base 1, that is, from the first position to the second position. At this time, the shell 21 moves downward relative to the first extruding portion 311 and the second extruding portion 312, and the above-mentioned first spring 12 is compressed, so that the drill bit 22 can extend to the lower part of the first extruding portion 311 and the second extruding portion 312 to drill a hole. After the drilling is completed, the longitudinal adjustment mechanism 8 drives the mounting base 1 to move upward on the movable base 5. During this process, the first spring 12 gradually returns to its natural state (due to the gravity of the first extrusion portion 311 and the second extrusion portion 312, the first spring 12 is stretched in its natural state. The first spring 12 first returns to its original length from the compressed state, and then is initially pulled up by the gravity of the first extrusion portion 311 and the second extrusion portion 312). The first extrusion portion 311 and the second extrusion portion 312 are kept in contact with the surface of the plate. During this process, the housing 21 moves upward relative to the fixed base 33, and the fixed base 33 slides from the second position to the first position on the mounting base 1. When the fixed base 33 returns to the first position, the first extrusion portion 311 and the second extrusion portion 312 can be driven by the fixed base 33 to move upward synchronously with the mounting base 1 together with the housing 21. When the fixing seat 33 moves up with the mounting seat 1 until it contacts the baffle 51, it is blocked by the baffle 51 and cannot move further up. At this time, the longitudinal adjustment mechanism 8 drives the mounting seat 1 to continue to move up. When the extrusion block 23 on the shell 21 contacts the adjustment rod and pushes the extrusion rod 6 away from one end of the first extrusion part 311 or the second extrusion part 312 to move upward, the extrusion rod 6 rotates relative to the first extrusion part 311 or the second extrusion part 312 and pushes the first extrusion part 311 or the second extrusion part 312 to rotate around its rotation axis. When the extrusion rod 6 rotates to a horizontal state, the fixing seat 33 is in the above-mentioned third position. At this time, the angle between the first extrusion part 311 and the second extrusion part 312 is the largest, that is, the extrusion cylinder 31 is in a fully open state.

[0047] In this embodiment, by rotating the extrusion rod 6 installed on the inner wall of the first extrusion part 311 and the second extrusion part 312, and cooperating with the baffle 51 set on the movable seat 5 to block the fixed seat 33, the mounting seat 1 can be driven to move upward, and the extrusion block 23 can be used to push the extrusion rod 6 to rotate, thereby passively driving the first extrusion part 311 and the second extrusion part 312 to rotate, completely pouring out the wood chips in the first extrusion part 311 and the second extrusion part 312, and also facilitating the replacement of the drill bit 22.

[0048] In another embodiment proposed by the present invention, the outside of the first extrusion portion 311 and the second extrusion portion 312 are both rotatably connected with an adjustment plate 9, and a third torsion spring is provided at the rotatable connection between the adjustment plate 9 and the first extrusion portion 311 or the second extrusion portion 312. When the third torsion spring is in a natural state, the side of the adjustment plate 9 away from the first extrusion portion 311 or the second extrusion portion 312 is lower than the first extrusion portion 311 and the second extrusion portion 312.

[0049] Specifically, in the above embodiment, the first extrusion portion 311 and the second extrusion portion 312 are in a vertical state completely relying on their corresponding first torsion springs. As the device is used, the first torsion spring gradually fails, which will cause the first extrusion portion 311 and the second extrusion portion 312 to be unable to fully contact each other. At this time, the lower surfaces of the first extrusion portion 311 and the second extrusion portion 312 will be in an inclined state, which will reduce the limiting effect of the plate and the effect of preventing wood chips from flying, and will not be able to prevent the surface of the plate from tearing; in this embodiment, the first extrusion portion 311 and the second extrusion portion 312 are both rotatably connected to an adjustment plate 9, and a third torsion spring (not shown in the figure) is provided at the position where the adjustment plate 9 is rotatably connected to the first extrusion portion 311 or the second extrusion portion 312. When the third torsion spring is in a natural state, the adjustment plate 9 is away from the first extrusion portion 311 or the second extrusion portion 312. The side of the adjusting plate 9 is lower than the lower surface of the first extrusion portion 311 and the second extrusion portion 312. With this arrangement, when the mounting seat 1 is driven to move downward, before the first extrusion portion 311 and the second extrusion portion 312 contact the plate, the side of the adjusting plate 9 away from the first extrusion portion 311 or the second extrusion portion 312 will preferentially contact the plate and rotate relative to the first extrusion portion 311 or the second extrusion portion 312 under the restriction of the plate. At this time, the third torsion spring gradually accumulates force, and the force of the third torsion spring on the first extrusion portion 311 or the second extrusion portion 312 will drive the first extrusion portion 311 and the second extrusion portion 312 to rotate and approach each other until the first extrusion portion 311 and the second extrusion portion 312 are completely in contact with each other, thereby ensuring that the first extrusion portion 311 and the second extrusion portion 312 can be adjusted to a state of contact with each other before contacting the plate.

It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims.
