Description

Technical Field

[0001] This application relates to the field of sawing auxiliary equipment, and in particular to a plate saw cutting depth adjustment device. Background Technology

[0002] Currently, common processing techniques for cutting and processing boards include cutting the boards and grooving the boards.

[0003] Grooving refers to cutting grooves of a certain depth into the surface of a board using a saw. However, current tabletop circular saws have many limitations in grooving boards, mainly in the following aspects: In a tabletop circular saw (hereinafter referred to as a saw), the saw blade protrudes from the table surface of the saw as the cutting part. When sawing a workpiece, the workpiece slides forward against the table surface of the saw, and is cut by the saw blade.

[0004] Thus, traditional circular saws are only suitable for grooving thicker workpieces. In order to adapt to the sawing of some plates, some circular saws are designed with height-adjustable saw blades, that is, the saw blades can be adjusted up and down relative to the machine table to adjust the height of the saw blade protruding from the table, thereby adapting to the grooving of thinner workpieces and adjusting the grooving depth.

[0005] However, while such saws with adjustable blade height can adapt to different grooving depths, they are relatively cumbersome to adjust. Specifically, the saw blade is mounted on the machine head, so adjusting the saw blade requires adjusting the entire machine head, which is quite laborious. Therefore, this application aims to provide a plate saw cutting depth adjustment device. Summary of the Invention

[0006] In order to solve at least one of the technical problems mentioned in the background art, the purpose of this application is to provide a plate saw cutting depth adjustment device.

[0007] To achieve the above objectives, this application provides the following technical solution.

[0008] This application provides a plate saw cutting depth adjustment device, which includes at least two support components for mounting on the saw machine platform and located on both sides of the saw blade. Each support component includes a carrier and a mounting part. The carrier can be mounted on the machine platform surface via the mounting part. The carrier includes a cross-section for supporting the plate and parallel to the machine platform surface. The cross-section can move vertically relative to the mounting part to adjust the vertical distance between the cross-section and the machine platform surface. A locking member is provided between the carrier and the mounting part for locking the relative position between the cross-section and the mounting part. In the working state, the cross-sections of the two support components are located on both sides of the saw blade and at the same height to jointly support the plate.

[0009] As an optional embodiment of this application, one of the carrier and the mounting part is provided with a vertically extending guide rod, and the other is provided with a slide for the guide rod to move vertically through. The guide rod passes into the slide so that the carrier can move vertically relative to the mounting part.

[0010] As an optional embodiment of this application, the locking component includes a locking bolt, and a carrier or mounting part, one of which is fixed with a sliding sleeve, and the sliding sleeve forms the slide rail; the locking bolt is threadedly connected to the sliding sleeve, and in the locked state, the inner end of the locking bolt extends into the slide rail to abut against the outer peripheral wall of the guide rod.

[0011] As an optional embodiment of this application, the guide rod is provided with scale lines distributed along the axial direction of the guide rod.

[0012] As an optional embodiment of this application, in at least one of the two support components, the support component further includes a positioning surface, the positioning surface being perpendicular to the support surface and protruding vertically upward from the support surface, and the positioning surface being parallel to the saw blade of the sawing machine.

[0013] As an optional embodiment of this application, the mounting part includes a fixed end and a locking member. The fixed end forms a slot for the table surface of the saw to be inserted into. The locking member is used to lock the table surface of the saw in the slot after it is inserted into the slot.

[0014] As an optional embodiment of this application, the locking element includes a locking bolt.

[0015] As an optional embodiment of this application, the fixed end includes a bent portion, and the bent portion and the mounting portion together form the bayonet.

[0016] As an optional embodiment of this application, the mounting part and / or carrier is in the form of a plate structure.

[0017] As an optional embodiment of this application, the bottom wall of the mounting part has a planar structure parallel to the cross-section.

[0018] Compared with the prior art, this application has the following advantages: As can be seen, in this scheme, the board is supported by two cross-sections located on both sides of the saw blade. At this time, the vertical distance between the cross-section and the highest point of the saw blade is equivalent to the depth of the groove formed by the subsequent sawing of the board.

[0019] Since the cross-section is vertically adjustable, the grooving depth can be adjusted by adjusting the vertical height of the cross-section. This device not only enables the circular saw to perform grooving, but also allows the grooving depth to be adjusted as needed.

[0024] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0025] Reference Figures 1-4 As shown, this embodiment provides a plate saw cutting depth adjustment device, which is applicable to circular saws for grooving plate M. In use, the device is installed on the circular saw to support the plate M in order to adjust the grooving depth of the plate M.

[0026] In related technologies, such as Figure 2 As shown, the circular saw (hereinafter referred to as the saw) mainly includes a horizontally arranged plate-shaped machine base 1, and a circular saw blade 11 (hereinafter referred to as the saw blade 11) mounted on the machine base 1 and driven to rotate by a motor. A cutter groove is provided on the machine base 1 corresponding to the position of the saw blade 11, and the upper part of the saw blade 11 extends out of the table surface of the machine base 1 through the cutter groove to serve as the sawing part. This type of saw has been extensively described and applied in existing technology, and will not be elaborated upon further here.

[0027] The device provided in this embodiment mainly includes at least two support components 2, which are respectively installed on the machine base 1 of the saw and located on both sides of the saw blade 11 of the saw. The structure of each support component 2 is basically the same, but there are slight differences in some embodiments. The specific differences will be described in the following description.

[0028] It is worth noting that the aforementioned "both sides of the saw blade 11" mainly refers to the two axial sides of the saw blade 11; the specific number of support components 2 can be determined according to actual needs, as long as there is at least one support component 2 on each side of the saw blade 11; for example, in this embodiment, the following will take the case of using two support components 2 as an example for specific explanation.

[0029] The reason for needing two support components 2 positioned on either side of the saw blade 11 is that, when grooving the plate M, both sides of the plate M extend towards both sides of the saw blade 11. By setting up two support components 2, the portions of the plate M located on either side of the saw blade 11 can be supported respectively. Figure 3 The state shown.

[0030] Among them, such as Figure 1 As shown, the support assembly 2 includes a carrier 22 and a mounting part 21. The mounting part 21, as the mounting part of the entire support assembly 2, is mainly used to attach the entire support assembly 2 to the table surface of the saw machine 1.

[0031] That is, the carrier 22 can be mounted on the table of the machine tool 1 via the mounting part 21; for example, in some embodiments, the mounting part 21 is mainly a plate structure, specifically, it is a long strip plate structure.

[0032] The mounting part 21 mainly includes a fixed end and a locking component. The fixed end has a slot 210 for the table surface of the saw machine 1 to be inserted into.

[0033] In some embodiments, combined with Figure 1 As shown, the specific structure of the bayonet 210 is as follows: the fixed end includes a bent portion 211, wherein the bent portion 211 can be integrally formed with the mounting portion 21, or it can be fixedly connected to the mounting portion 21 by a fixed connection means, such as screw connection, welding, riveting and other fixed connection methods, which are not specifically limited here.

[0034] The bending portion 211 is basically L-shaped, and it and the mounting portion 21 together form the bayonet 210, with the opening direction of the bayonet 210 facing the length direction of the mounting portion 21.

[0035] The locking component is used to lock the table of machine 1 into the slot 210 after the table of machine 1 is engaged in the slot 210.

[0036] In some embodiments, the locking element may be a locking bolt 23, and the specific method of locking using the locking bolt 23 may be as follows: The locking bolt 23 extends vertically and is threaded through the bent portion 211. When fixing the mounting portion 21, as follows: Figure 4 As shown, the mounting part 21 is placed on the table surface of the saw machine base 1, and then the bayonet 210 of the mounting part 21 is snapped into the end side of the machine base 1.

[0037] The term "end side" here can be understood as follows: the direction that is horizontal and perpendicular to the axial direction of the saw blade 11 is denoted as the first direction. In this case, the aforementioned end side refers to the end of the machine base 1 in the first direction.

[0038] After the bayonet 210 is engaged with the end of the machine base 1, tighten the locking bolt 23 so that the inner end is pressed against the bottom wall of the machine base 1. At this time, the entire mounting part 21 is fixed to the machine base 1.

[0039] To position the mounting part 21 so that its length is parallel to the disc surface of the saw blade 11 after it is mounted on the machine base 1, in some embodiments, such as... Figure 4 As shown, the side wall opposite to the opening side of the bayonet 210 is a vertically arranged plane. When this plane is in contact with the end side of the machine base 1, the length direction of the mounting part 21 is parallel to the saw blade 11.

[0040] The carrier 22 is mainly used to support the plate M, and it mainly includes a carrier surface 221 that supports the plate M and is parallel to the table surface of the machine tool 1. During operation, the plate M is placed on the carrier surface 221, and the plate M is pushed to slide forward along the carrier surface 221 to realize the grooving process of the plate M.

[0041] Specifically, in the working state, which can be understood as the state in which the device is fixed on the machine base 1, the cross-sectional surfaces 221 of the two support components 2 are respectively located on both sides of the saw blade 11 of the saw and at the same height to jointly support the plate M, such as... Figure 3 As shown.

[0042] It is understandable that when grooving the sheet M, the side of the sheet M to be grooved (i.e. the processing surface) is facing down, that is, the processing surface of the sheet M is in contact with the aforementioned cross surface 221.

[0043] In order to adapt to grooving processes of different depths, in this embodiment, the cross surface 221 is designed to be adjustable. Specifically, the cross surface 221 can move vertically relative to the mounting part 21 to adjust the vertical distance between the cross surface 221 and the table surface of the machine tool 1.

[0044] The aforementioned groove depth can be understood as the depth of the groove in the direction perpendicular to the machined surface.

[0045] As can be seen, in this scheme, the plate M is supported by two cross surfaces 221 located on both sides of the saw blade 11. At this time, the vertical distance between the cross surface 221 and the highest point of the saw blade 11 is equivalent to the depth of the groove formed by the subsequent sawing of the plate M.

[0046] In other words, the higher the cross-section 221 is relative to the machine tool 1, the smaller the depth of the groove formed subsequently.

[0047] In addition, in order to make the cross surface 221 parallel to the machine base 1, in some embodiments, the cross surface 221 is parallel to the bottom surface of the mounting part 21, and the bottom surface of the mounting part 21 is a horizontally arranged planar structure.

[0048] In some embodiments, the carrier 22 has a long strip-shaped structure, and the top surface of the carrier 22 constitutes the cross surface 221.

[0049] In order to enable the cross surface 221 to be vertically adjusted relative to the machine base 1, in some embodiments, a guide rod 24 extending vertically downward is fixed to the bottom of the end side of the carrier 22, and a slide rail is provided on the mounting part 21 corresponding to the position of the guide rod 24 for the guide rod 24 to move vertically through. The guide rod 24 passes into the slide rail so that the carrier 22 can move vertically relative to the mounting part 21.

[0050] It is worth noting that in some other alternative embodiments, the positions of the guide rod 24 and the slide rail can be interchanged; that is, the guide rod 24 can also be provided on the mounting part 21, while the slide rail is provided on the carrier 22. This method can also achieve vertical relative movement between the carrier 22 and the mounting part 21.

[0051] The slide can be formed by fixing a sliding sleeve 25 on the carrier 22, and the slide is formed by the sliding sleeve 25, which vertically penetrates the mounting part 21.

[0052] It is worth noting that, in order to prevent the guide rod 24 from rotating circumferentially within the slide, in some embodiments, two sets of guide rods 24 are provided, located at both ends of the carrier 22 respectively.

[0053] Of course, in some other alternative embodiments, only one guide rod 24 may be provided, wherein the radial cross section of the guide rod 24 has edges, for example, the radial cross section is a polygon, such as a triangle, a quadrilateral, etc., and the slide is adapted to the radial cross section. In this way, the guide rod 24 can also be prevented from rotating circumferentially within the slide.

[0054] In addition, in order to keep the cross surface 221 of the carrier 22 in its current position during operation, in some embodiments, a locking member is provided between the carrier 22 and the mounting part 21 for locking the relative position between the cross surface 221 and the mounting part 21.

[0055] In some embodiments, the locking member may be a locking bolt 251.

[0056] The specific structure of the locking mechanism using locking bolt 251 is as follows: The locking bolt 251 is threaded onto the sliding sleeve 25, wherein the locking bolt 251 is preferably arranged radially along the sliding sleeve 25.

[0057] When locking is required, rotate the locking bolt 251 so that the inner end of the locking bolt 251 abuts against the outer peripheral wall of the guide rod 24. At this time, the guide rod 24 is locked and cannot slide up and down in the slide, which in turn locks the height of the cross surface 221 relative to the machine base 1, and then enters the locked state.

[0058] In some embodiments, in order to intuitively indicate the height of the cross surface 221, the guide rod 24 is provided with scale lines distributed along the axial direction of the guide rod 24. During operation, a reference is selected (for example, the lower end of the sliding sleeve 25 is used as a reference), and the scale lines are used to indicate the height of the cross surface 221.

[0059] Under certain working conditions, the grooves formed need to be basically parallel to the length direction of the plate M. Based on this working condition, the plate M needs to maintain a straight line when it is moving forward to cut the groove.

[0060] Therefore, in some embodiments, in order to guide the sheet material M to move forward in a straight line, at least one of the two support components 2 includes a positioning surface 222 on its carrier 22. For example, this embodiment shows that only one carrier 22 has a positioning surface 222 formed on it, wherein the positioning surface 222 is mainly for the side of the sheet material M to abut.

[0061] The positioning surface 222 is perpendicular to the cross surface 221 and protrudes vertically upward from the cross surface 221, which is equivalent to the cross surface 221 and the positioning surface 222 intersecting perpendicularly to form an L-shaped structure.

[0062] Furthermore, the positioning surface 222 is parallel to the saw blade 11 of the sawing machine, which can also be understood as the positioning surface 222 being horizontally perpendicular to the axial direction of the saw blade 11; thus, when the plate M moves forward while adhering to the positioning surface 222, it can be ensured that the plate M is grooved in a basically straight-line state.

[0063] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution disclosed in this application can be achieved, and this is not limited herein.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0065] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application.
