Description

Technical Field

[0001] This invention relates to a table-type tool and a workbench. Background Technology

[0002] Table-type tools are among the most widely used tools, commonly used in cutting and grinding operations. Taking cutting as an example, a table-type tool typically includes a worktable and a saw blade mounted on it. Materials cut include wood, plastic, and metal. During cutting, it's crucial to ensure the parallelism between the workpiece edge and the cut kerf; this is usually achieved by installing a guide rail on the worktable. With the increasing sophistication of manufacturing processes, users demand higher precision. On one hand, existing guide rail structures struggle to meet the required parallelism precision. Some lack adjustment mechanisms altogether, while others, even those with such mechanisms, are overly complex and inaccurate. On the other hand, defects in the fixing structure between the guide rail and the worktable can also lead to these parallelism adjustment errors. Summary of the Invention

[0003] To address the shortcomings of existing technologies, the present invention aims to provide a table-type tool and worktable with high precision and strong stability.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A table-type tool includes: a worktable having a working surface for placing a workpiece; a slide rail connected to the worktable, including at least one groove and a first sidewall connected to the worktable and a second sidewall away from the worktable; a rail on the worktable, at least one end of which is movably connected to the slide rail; and a locking device including a locking component and a fine-tuning component, the locking device being used to movably connect the rail to the slide rail and to lock the rail to the slide rail via the locking component, wherein the locked rail is movable via the fine-tuning component.

[0006] A worktable includes: a slide rail connected to the worktable, including at least one groove and a first sidewall connected to the worktable and a second sidewall away from the worktable; a rail on the worktable, one end of which is movably connected to the slide rail, and the other end which is suspended or abuts against the work surface; a locking device including a locking assembly, the locking device being used to movably connect the rail to the slide rail and lock the rail to the slide rail by the locking assembly; the locking device further includes a first support position and a second support position, the first support position abutting against the groove and the second support position abutting against the second sidewall.

[0007] In some embodiments, one end of the gate is movably connected to the slide rail, and one end of the gate is suspended or abuts against the working plane.

[0008] In some embodiments, the locking device includes a first support position and a second support position, the first support position abutting against the slide groove and the second support position abutting against the second sidewall.

[0009] In some embodiments, the fine-tuning component is a second support position, and the fine-tuning component is slidable on the second sidewall.

[0010] In some embodiments, the second sidewall is provided with a motion groove, and the fine-tuning component has a structure that engages with the shape of the motion groove.

[0011] In some embodiments, the first support position is located in the groove.

[0012] In some embodiments, the locking device includes a movable handle and a linkage assembly connected to the movable handle, the linkage assembly being connected to a locking assembly, the locking assembly being disposed in the slide groove; the movable handle drives the locking assembly to move via the linkage assembly, thereby causing the locking assembly to separate from or lock with the slide groove.

[0013] In some embodiments, the linkage assembly includes an active link and a driven link connected to each other, the active link being connected to a movable handle, the driven link being connected to the locking unit, and the driven link moving under the action of the active link.

[0014] In some embodiments, the locking device includes a guide assembly disposed in a groove and movable along the groove.

[0015] In some embodiments, the fine-tuning component includes:

[0016] The fine-tuning wheel moves relative to the slide rail under the action of the user;

[0017] The movable part has one end that is either separate from or connected to the fine-tuning wheel, and the other end that abuts against the second sidewall.

[0018] The guide hub is located on the second side wall and moves on the second side wall under the action of the movable part.

[0019] The advantages of this invention are: its structure achieves a seamless connection between the locking device and the slide rail using its own weight, ensuring the parallelism and accuracy of the rails from the outset. After the user adjusts the position, it can quickly and automatically or self-adjust for parallelism. The fine-tuning structure and locking device are integrated into one unit, making operation convenient without occupying more space and reducing costs. The locking device provides a large locking torque amplification structure, ensuring locking strength, user convenience, and user comfort. Attached Figure Description

[0032] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0033] Example 1

[0034] like Figure 1As shown, this invention relates to a bench-type tool 100, which includes a worktable 200 and a guide rail 300 disposed on the worktable 200. The worktable 200 has a working surface capable of placing a workpiece, and a slide rail 600 is provided on one side of the worktable. Specifically, the working surface is the upper surface of the worktable 200. The tool portion of this bench-type tool is not shown in the figure; the tool is disposed within a mounting hole 201 on the worktable 200. In this embodiment, the tool can be a cutting assembly, a grinding assembly, or a drilling device, etc., and is not limited thereto.

[0035] A guide rail 300 is disposed on the working plane and on one side of the mounting hole 201 to hold the workpiece against the guide rail 300 and the tool. The guide rail 300 is a long and narrow cuboid and is disposed along the first axis 301. Specifically, for example, when the workpiece to be cut needs to be cut into straight strips, the first axis 301 is parallel to the direction of the cutting tool.

[0036] At least one end of the rail 300 is movably connected to the slide rail 600 via a locking device 400. Specifically, when only one end of the rail 300 is connected to the slide rail 600, the slide rail 600 is provided, and the locking device 400 is located between the slide rail 600 and the rail 300. In this case, the other end of the rail 300 is suspended or rests against the working surface. In this embodiment, the rail 300 has a certain gap with the working surface, which facilitates the movement of the rail above the worktable and ensures smooth sliding. This structure only provides the slide rail 600 and the locking device 400 on one side of the worktable 200, which is beneficial for miniaturizing the table tool and making it easier to process and manufacture. Furthermore, the suspended end of the rail 300 is located in the middle of the worktable 200 or near the edge of the worktable away from the locking device 400. The length of the rail is related to the size of its worktable and the weight of the rail itself, and this length should ensure that it can be parallel to the working surface. In other embodiments, locking devices are provided at both ends of the guardrail 300, and slide rails are provided on opposite sides of the worktable. Preferably, the guardrail has a certain gap with the working plane. This structure is suitable for larger table-shaped tools. In other embodiments, there is no gap between the guardrail 300 and the working plane of the worktable 200 in the locked state, which is not limited here.

[0037] like Figure 3As shown, the locking device 400 includes a housing 401 connected to a connecting portion 402, and a retaining gate 300 fixedly connected to the connecting portion 402. Specifically, the retaining gate 300 is a hollow shell shape with at least one open end. The connecting portion 402 extends into the interior of the retaining gate 300 through the opening, and at least one wall surface of the connecting portion 402 is fixedly connected to one wall surface of the retaining gate 300. Further, the connecting portion 402 has a protrusion and a corresponding groove on the inner wall of the retaining gate, so that the connecting portion 402 achieves a guiding and fixing function when it extends into the retaining gate 300. One end face of the housing 401 abuts against one end of the retaining gate 300, and the connecting portion 402 is perpendicular to this end face.

[0038] The housing 401 comprises, from top to bottom, a hinge seat 401c, a trapezoidal portion 401a, and a movable base portion 401b. The hinge seat 401c is a boss located at one end of the upper surface of the trapezoidal portion 401a, and has a connecting hole through which the hinge shaft 411 passes. The cross-section of the trapezoidal portion 401a perpendicular to the left-right direction is approximately trapezoidal, but can also be rectangular, triangular, etc. The upper surface of the trapezoidal portion 401a is close to a first fixed shaft 421, and the upper surface also has a through hole for the active connecting rod to pass through. The trapezoidal portion 401a contains most of the connecting rod assembly 420. The movable base portion 401b is wider than the trapezoidal portion 401a in the left-right direction, and the trapezoidal portion 401a is located in the middle of the movable base portion 401b. The movable base 401b contains at least a portion of the connecting rod assembly 420, a majority of the locking assembly 440, a fine-tuning assembly 430, a guide assembly 450, and an elastic element 460.

[0039] A movable handle 410 is provided on the upper part of the housing 401. The movable handle 410 is hinged to the housing 401 and rotates along a hinge axis 411. In other embodiments, the movable handle 410 may also move vertically up and down or horizontally in a certain direction, and there is no limitation here. Furthermore, the movable handle 410 is located outside the housing 401, partially covering the housing 401 and other structures of the locking device 400.

[0040] like Figure 3-4 As shown, the movable handle 410 is connected to one end of the linkage assembly 420 and drives the linkage assembly 420 to move. Specifically, the linkage assembly 420 includes a driving link 422 and a driven link, the driven link further including a first driven link 423 and a second driven link 424. One end of the driving link 422 is fixedly connected to the inside of the movable handle 410 via a first fixed shaft 421. Further, the end of the driving link 422 connected to the movable handle 410 extends out of the housing 401. Figure 4 As shown, when the movable handle 410 is in the lowered state, the first fixed shaft 421 abuts against the outside of the housing 401. Correspondingly, the housing 401 is provided with a through hole for the active connecting rod 422 to pass through.

[0041] like Figure 4 , Figure 7 As shown, the end of the active link 422 away from the movable handle 410 is connected to the first driven link 423 and the second driven link 424. The other end of the first driven link 423 is fixedly connected to the housing 201 via the second fixed shaft 425, and the first driven link 423 rotates around the second fixed shaft 425. The other end of the second driven link 424 is fixedly connected to the locking assembly 440. The movement of the active link 422 drives the driven link to move, which in turn drives the locking assembly 440 to move between the locked position and the unlocked position. Further, both the active link 422 and the first driven link 423 are generally composed of two connecting pieces connected together. The two connecting pieces of the first driven link 423 are sleeved on the outside of the active link 422 and are connected to each other via the third fixed shaft 426. One end of the second driven link 424 is connected to the third fixed shaft 426. Specifically, one end of the second driven link 424 is threaded and screwed into the middle of the third fixed shaft 426. The other end of the second driven link 424 can also be connected to the upper part of the locking assembly 440 in the same way. When the locking assembly is in the locked position, the first driven link 423 and the second driven link 424 move to a parallel state. The structure of the above-mentioned link assembly ensures the connection strength of each component while also providing the required degree of freedom of movement, and the structure is easier to assemble and connect. In addition, a large amplified torque can be provided near the dead point of the locked position. For example, the magnification is 200 times in this embodiment, which can provide a comfortable handle locking feel.

[0042] The locking assembly 440 includes a base 442 and a locking element 441. The upper part of the base 442 is connected to the second driven link 424. The locking element 441 is generally L-shaped and includes a bent edge whose shape matches the shape of the groove on the slide rail 600. Specifically, the slide rail 600 includes a first groove 601 and a second groove 602. The locking element 441 is disposed in the first groove 601, and when in the locked state, its bent edge rests against the inner wall of the first groove 601. Further, the inner wall extends along a first direction, which is perpendicular to or inclined relative to the working plane. When inclined, the inclination direction of the first direction is consistent with the separation movement direction of the locking element. That is, when the locking element moves from the locked position to the separation position behind the slide rail, the first direction is inclined relative to the rear of the slide rail, which makes the locking more secure. Figure 4 As shown, the locking assembly 440 is located at the lower front part of the housing 401, and an elastic element 460 is provided between the locking assembly 440 and the housing 401. Specifically, one end of the elastic element 460 is fixed to the base 442, and the other end is fixed to the inner wall of the housing 401. When the locking assembly 440 is in the locked position, the elastic element 460 is in a natural state or a slightly stretched state.

[0043] The slide rail 600 includes a first sidewall connected to the worktable 200 and a second sidewall away from the worktable. The locking device 400 includes a first support position and a second support position, the first support position abutting against the inner wall of the slide groove, and the second support position abutting against the second sidewall of the slide rail. In one embodiment, the first support position is the plane in contact with the inner wall of the slide groove for the locking element 442.

[0044] The locking device 400 also includes a fine-tuning component 430. The fine-tuning component 430 contacts the second sidewall, and the contact surface (or line) forms a second support position. Specifically, as... Figure 1 As shown, the fine-tuning component 430 is at least one roller connected to the housing 401. In this embodiment, two rollers are provided, symmetrically arranged on both sides of the connecting rod assembly. Further, each roller consists of two smaller rollers, upper and lower, with an hourglass-shaped cross-section. A groove is formed between the smaller rollers, the diameter of which is smaller than the diameter of the smaller rollers. Correspondingly, the second sidewall protrudes outward to form a movement groove, specifically a convex groove. This groove cooperates with the convex groove, allowing the locking device 400 to move along the convex groove. The groove, convex groove, and cross-sectional gap can be "V-shaped," stepped, etc. At least a portion of the roller is located outside the housing 401, or flush with the outer surface of the housing, allowing the user to directly rotate the roller. The structure of the convex groove and groove on the second support surface cooperates, ensuring that the fine-tuning component always generates internal locking stress regardless of whether the locking assembly is locked or disengaged. No matter the force applied from the front, back, left, right, up, or down directions, the locking device and the second support surface cannot disengage from the slide rail. During replacement and disassembly, simply lift the suspended end of the gate (i.e., the end furthest from the locking device) to counteract its weight's effect on the structure, and the gate can be removed. This method of detachment makes replacement and disassembly very simple. Similarly, assembly of the structure is also very simple. In other embodiments, rollers may be omitted, and a surface-contact sliding friction structure may be used directly; this is not a limitation.

[0045] The locking device 400 also includes a guide assembly 450 disposed within the slide groove for guiding. For example... Figure 5-6 As shown, the guide assembly 450 includes a fixed base 452 and a roller 451 disposed within the fixed base. The fixed base 452 is fixedly connected to the housing 401. The roller can be a cylinder that rotates along an axis or a sphere. The fixed base 452 is placed inside the housing 401, and its width is slightly smaller than the width of the housing 401 in the left-right direction. Its height is less than or equal to the depth of the slide groove, or slightly greater than the depth of the slide groove, to ensure motion stability while achieving structural compactness. In other embodiments, the roller may not be provided, and the fixed base directly contacts the second slide groove 602, with the locking device 400 moving on the slide groove through contact friction.

[0046] When the height of the fixed seat 452 is slightly greater than the depth of the slide groove, the fixed seat 452 protrudes from the upper end of the second slide groove 602, and the position of the second fixed shaft 425 is higher than the upper end of the fixed seat 452, so that the lower edge of the first driven link 423 is higher than the upper end of the fixed seat 452. At this time, the driven link is inclined relative to the working plane in the locked state.

[0047] In this embodiment, the slide rail includes a first slide rail 601 and a second slide rail 602. The locking component 440 is disposed within the first slide rail 601. The guide component 450 can be disposed together with the locking component 440 within the first slide rail 601, in which case they are arranged side-by-side in the left-right direction. Alternatively, the guide component 450 can be disposed within the second slide rail 602, in which case they are arranged side-by-side in the front-back direction. In the first case, the front-back width of the entire slide rail is smaller. In the second case, the locking device 400 has a smaller left-right width, making it more compact. In the third case, the guide component 450 can be disposed together with the locking component 440 within the first slide rail 601, abutting against opposite side walls and arranged side-by-side in the front-back direction. In this case, the slide rail has only one slide rail, but the total width of the slide rail is approximately the sum of the first and second slide rails, and the total width of the slide rail is slightly smaller than in the second case. The positional relationship between the guide component 450 and the locking component will not be exhaustively listed here. Regardless of the above situation, the guide component 450 and the locking component 440 together form the second support position.

[0048] The working principle of the table-type tool in this embodiment is as follows:

[0049] Taking cutting as an example, when cutting a workpiece, the position of the guide rail 300 needs to be adjusted so that the workpiece rests against the guide rail to complete a cut of a certain size. At this time, the guide rail 300 is in a locked state. Lifting the movable handle 410 upwards causes the ends of the first and second driven links connected to the driving link to move upwards under the action of the driving link 422, that is, the first and second driven links rotate clockwise and counterclockwise respectively. The second driven link 424 drives the locking assembly 440 to move away from the inner wall of the slide groove, and the elastic element 460 is stretched by the second driven link. At this time, the locking device is in a disengaged state. Moving the guide rail 300 to the desired position, the locking device moves on the slide rail under the guidance of the guide assembly. When the guide rail 300 is in the target position, pressing the movable handle 410 downwards restores the locking assembly 440 to the locked state based on the above principle. If there is an error in the position, and the guide rail needs to be fine-tuned, the roller of the fine-tuning assembly is turned to adjust the position of the guide rail.

[0050] In existing technologies, locking or fine-tuning devices inevitably have gaps with the guide rail due to errors or the need to meet sliding requirements. These gaps prevent the parallelism of the guide rail and the tool from being guaranteed, requiring users to make multiple adjustments to ensure a certain level of parallelism, and sometimes even failing to achieve accurate adjustment. Rapidly moving the guide rail cannot achieve accurate distance from the saw blade, so users need to fine-tune the guide rail near the cutting range to achieve precise positioning. Because of these gaps, when adjusting the guide rail within a small range, it's uncertain whether the two ends are aligned. Often, after adjusting one end, the other end cannot follow suit to parallelism, or when adjusting the second end, the adjusted end moves with the one being adjusted. To solve this problem, this invention makes the aforementioned improvement. This invention achieves a seamless connection between the locking device and the guide rail, ensuring the parallelism and accuracy of the guide rail from the outset. After the user adjusts the position, parallelism can be quickly achieved. The fine-tuning structure and locking device are integrated into one unit, making operation convenient, saving space, and reducing costs. The locking device provides a large locking torque amplification structure, ensuring locking strength, user convenience, and user comfort. Specifically, under the influence of gravity, the downward component of gravity causes the first support position to press firmly against the slide groove, and the roller at the second support position to engage with the protrusion. With this structure, regardless of whether the locking assembly is in the locked or disengaged position, a gapless connection between the first and second support positions is always guaranteed, thus ensuring the parallelism between the guard and the tool.

[0051] Example 2

[0052] like Figure 9-12 As shown, structures that are the same as or similar to those in Embodiment 1 are numbered in the same way or without additional labeling. For convenience, this embodiment only describes the differences from Embodiment 1.

[0053] In this embodiment, the fine-tuning component 430 is also located at the end of the housing 401. The structure of the fine-tuning component 430 is different from that in the first embodiment. It includes a fine-tuning wheel 431 for user control and a guide wheel hub 436 located on the second side wall of the guide rail. By adjusting the fine-tuning wheel 431, the user causes the fine-tuning component 430 to drive the guide wheel hub 436 to move along the second side wall of the guide rail 600.

[0054] Specifically, such as Figure 10-12As shown, the fine-tuning component 430 includes a movable member 433, one end of which is connected to the fine-tuning wheel 431 in a certain state. Further, during fine-tuning, the movable member 433 is connected to the fine-tuning wheel 431; in other states, one end of the movable member 433 is separated from the fine-tuning wheel 431. This change in state is achieved by the user pressing the fine-tuning wheel 431. In other embodiments, other control methods may also be used. Specifically, the fine-tuning wheel 431 includes a fine-tuning motion part 431a and fine-tuning connecting parts 431b located at both ends, such as... Figure 11 As shown, the fine-tuning motion part 431a and the fine-tuning connecting part 431b are roughly cross-shaped, with the extension direction of the fine-tuning connecting parts 431b on both sides perpendicular to the movement direction of the fine-tuning motion part 431a. The fine-tuning connecting part 431b has spiral patterns or grooves, and the movable part 433 has a corresponding structure to allow it to connect with the fine-tuning connecting part 431b. Furthermore, since there are two fine-tuning connecting parts 431b in this embodiment, two movable parts 433 can also be provided accordingly, and the two movable parts can be connected by a mechanism. Alternatively, the movable part 433 can be an integral structure with two connecting arms, which are respectively connected to the fine-tuning connecting parts 431b. In other embodiments, the structure of the movable part 433 is determined by the structure of the fine-tuning connecting part 431b, and can be adjusted accordingly; this is not limited here. The outer ends of the two fine-tuning connecting parts 431b abut against the inner wall of the housing 401, allowing the fine-tuning wheel 431 to move in a fixed direction under the user's action.

[0055] The fine-tuning assembly 430 also includes a reset mechanism, which comprises a reset spring 432 and a reset spring 437. The first end of the reset spring 432 is fixed to the housing, and the second end is located between the fine-tuning motion part 431a and the movable member 433. The reset spring 437 is disposed between the movable member 433 and the housing 401. The movable member 433 also includes a receiving groove 433a for accommodating one end of the reset spring. The second end of the reset spring 432 can elastically deform within a certain range. When performing a fine-tuning action, the user presses or pushes the fine-tuning wheel 431, compressing the reset spring 432 and deforming the reset spring 437. After the fine-tuning is completed, the fine-tuning wheel 431 returns to its original position under the elastic restoring force of the reset spring 432 and the reset spring 437.

[0056] The structure of the guide hub 435 is similar to that of the roller structure in Embodiment 1, and will not be described in detail here. At least one guide hub 435 is provided; in this embodiment, two are spaced apart. A movable member 433 is provided between the two guide hubs 435, and the movable member 433 and the guide hub 435 preferably also have a certain gap. The two guide hubs 435 are connected by a guide housing 437. The width of the guide housing 437 in the left-right direction is greater than the width of the fine-tuning wheel 431 in the left-right direction to ensure the stability of the fine-tuning assembly.

[0057] One end of the movable component 433 abuts against the second side wall of the slide rail 600, or is directly connected to the guide housing 437 outside the guide wheel hub 436. In this embodiment, this end of the movable component 433 is located between the two guide wheel hubs, passes through the guide housing 437, and abuts against the second side wall of the slide rail 600. Similar to Embodiment 1, the second side wall of the slide rail in this embodiment also has a V-shaped or protruding groove, and the end of the movable component 433 has a structure of a corresponding shape that engages with the second side wall.

[0058] The fine-tuning component 430 includes a housing 438, which houses and partially accommodates the entire structure of the fine-tuning component 430 and is connected to the housing 401. The housing 438 primarily provides support for the lower part of the component, while the housing 401 covers the fine-tuning component 430 in the left, right, front, and rear directions. The fine-tuning wheel 431 protrudes from the opening in the housing 401, with its front end slightly extending beyond or flush with the housing 401.

[0059] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the above embodiments do not limit the present invention in any way, and all technical solutions obtained by equivalent substitution or equivalent transformation fall within the protection scope of the present invention.
