Description

Technical Field

[0001] This invention relates to the field of industrial equipment technology, and in particular to a workbench with a replaceable auxiliary table. This workbench is suitable for various industrial production and processing fields such as machining and manufacturing, woodworking, profile cutting, welding, laser cutting, and precision engraving, and is especially suitable for working environments requiring frequent adjustments to workpiece position and orientation. Through innovative mechanical structure design, this invention solves the problem of the lack of flexibility of traditional workbenches when dealing with workpieces of different sizes and types, providing a new technical solution for improving work efficiency and adaptability. Background Technology

[0002] In many fields such as machining and manufacturing, woodworking, and profile cutting, workbenches are indispensable pieces of equipment. Traditional workbenches are usually of fixed dimensions; however, in processes such as welding, laser cutting, precision carving, and material cutting, the length and size of the workpiece often need to be changed or repositioned, and the offset of the workpiece's center of gravity also requires a change in the position of the support surface. Therefore, traditional workbenches are difficult to adapt to these diverse work requirements.

[0003] To expand their applications, some designers have developed adjustable worktables, but these improvements still have many limitations. Existing adjustable worktables typically face the following problems: 1. Limited flexibility: The extended or widened parts can often only be used in a single direction and cannot be flexibly transferred to other surfaces.

[0004] 2. Complex operation: Even if it can be converted, the operation process is often cumbersome and complicated, which affects work efficiency.

[0005] 3. Decreased stability and load-bearing capacity: The adjustment mechanism may affect the stability and load-bearing capacity of the worktable.

[0006] 4. Limited adjustment range: Most adjustable worktables have a limited adjustment range, making it difficult to meet the needs of work with extreme dimensions.

[0007] 5. Reduced portability: Some designs may increase the overall weight of the workbench, affecting its portability and ease of storage.

[0008] In recent years, the design and function of workbenches have been continuously innovated to meet the needs of specific industries. For example, in the field of welding, patent announcement number CN 216576292 U discloses a wire rod welding workbench with an auxiliary support structure. This workbench includes a main workbench, a positioning assembly, and an auxiliary support assembly. The positioning assembly, located at the top center of the workbench, consists of a positioning groove, a threaded rod, and a clamping plate, enabling precise positioning of the workpiece to be welded. The auxiliary support assembly is located in grooves at both ends of the workbench, enhancing its stability. Furthermore, the workbench is equipped with an adjustable protective assembly that effectively shields the welding process from debris and sparks, improving operational safety.

[0009] In the automotive manufacturing sector, authorization notice number CN 217596414 U introduces an innovative tightening auxiliary worktable. Developed by GAC Motor Co., Ltd., this worktable is primarily used for tightening assembly operations at fastening points between parts and subframes. Its core features include a positioning mechanism, a tightening auxiliary mechanism, and a clearance groove design. This design enables bottom-up tightening assembly operations, reducing manual labor and improving production efficiency and accuracy.

Detailed Implementation

[0038] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0039] The following is a combination of all the appendices Figure 1-9 The embodiments of the present invention will be described in detail below.

[0040] Example 1: The tabletop shape of most workbenches is square or rectangular, and the tabletop shape of this embodiment is also designed for these two common shapes. A workbench with a replaceable auxiliary table has the following structure: 1) Main work surface 10: serves as the main operating plane of the workbench. 2) Support structure 20: used to support the main table 10 and ensure the stability of the entire workbench.

[0041] 3) Auxiliary tabletop 30: Adjustably installed on one side of the main tabletop 10 via the connecting structure 40.

[0042] 4) Connection structure 40: realizes the connection and adjustment function between the auxiliary tabletop 30 and the main tabletop 10.

[0043] For ease of description, please refer to the appendix. Figure 1Establish an X / Y / Z three-axis coordinate system. In this coordinate system, the auxiliary platform 30 can be installed on either side of the main platform 10 in the X-axis or Y-axis direction.

[0044] The design of the connection structure 40 has several innovative features: Sliding adjustment: Allows the auxiliary table 30 to slide and adjust its position on the side of installation to accommodate workpieces of different sizes or operational needs.

[0045] Locking mechanism: After being adjusted to the appropriate position, the auxiliary tabletop 30 can be firmly locked to ensure working stability.

[0046] Folding storage: When the auxiliary work surface 30 is not needed, it can be folded and stored to save space and improve the flexibility of the work surface.

[0047] Steering function: The auxiliary table 30 can be steered to an adjacent surface, for example, from the X-axis to the Y-axis, or vice versa. This design greatly increases the adaptability of the worktable, enabling it to meet various complex work requirements.

[0048] Specifically, the structure and function of the connection structure 40 are as follows: 1) Right-angle guide rail 41: The right-angle guide rail 41 is a one-piece L-shaped structure, seamlessly connected by two mutually perpendicular strip rails. This guide rail is installed on two adjacent edges of the main tabletop 10, forming a precise right angle. Its main function is to provide a sliding and positioning track for the auxiliary tabletop 30. High-strength, high-wear-resistant alloy materials are selected, such as 7075 aerospace aluminum alloy or 440C stainless steel.

[0049] 2) Sliding connector 42: Installed on the lower surface of one side of the auxiliary platform 30, it serves as a load-bearing and support for the auxiliary platform 30, forming a sliding engagement with the right-angle guide rail 41, allowing the auxiliary platform 30 to move smoothly along the guide rail. Typically, two rails are provided, parallel to each other. The spacing between the two rails is appropriately selected based on the rationality of the support and the dimensions of the auxiliary platform 30 to ensure stability and load-bearing capacity. The use of low-friction materials or roller designs can be considered to reduce resistance during movement.

[0050] 3) Pivot 43: Vertically fixed at the intersection of right-angle guide rails 41, the main body is made of high-strength materials, such as heat-treated alloy steel or titanium alloy, ensuring high strength and wear resistance. Pivot 43 is equipped with a controllable lifting mechanism in the vertical direction, such as a precision screw lifting system or a hydraulic cylinder lifting device. Lifting control can be manual or electric, and is equipped with a position control system. As the fulcrum for the steering of the auxiliary platform 30, pivot 43 should also ensure good lubrication to achieve smooth rotation.

[0051] 4) Sliding controller 44: It is fixed on an auxiliary platform 30 between two sliding connectors 42, wherein the upper surface is flush with or slightly lower than the auxiliary platform 30. Its structure and function are as follows: a. An operating part is provided on the upper surface. The operating part is designed to be easy to operate, such as a handle or knob that can be turned with a wrench, for controlling the position locking and unlocking of the auxiliary table 30.

[0052] b. The lower surface has a guide surface 01 and a mating hole 02. The guide surface 01 is precisely fitted with the right-angle guide rail 41 to guide the auxiliary platform 30 to accurately enter the pivot position 43 for pivoting. The pivot 43 is precisely fitted with the mating hole 02 to ensure the stability and accuracy of the rotation process.

[0053] c. An internal locking mechanism is integrated, which can employ existing technologies such as spring-loaded pins, friction braking devices, or electromagnetic locks to ensure that the auxiliary platform 30 can be securely locked in any position.

[0054] Operating principle: The main work surface 10 serves as the basic working plane, and the auxiliary work surface 30 is connected to the right-angle guide rail 41 through the sliding controller 44 and the sliding connector 42.

[0055] Under normal use conditions: 1. Sliding adjustment: S1 Unlock the sliding controller 44; S2 The auxiliary table 30 can slide freely along the right-angle guide rail 41 to achieve precise position adjustment in the X-axis or Y-axis direction; S3 After adjusting to the desired position, lock the sliding controller 44 to fix the auxiliary table 30.

[0056] 2. Direction Conversion: When it is necessary to change the working direction, the operation steps are as follows: S1. Unlock the sliding controller 44; S2. Operate the handle or knob of the sliding controller 44 to guide the auxiliary table 30 to move smoothly along the right-angle guide rail 41 to the position of the pivot 43; S3. After reaching the position of the pivot 43, the mating hole 02 of the sliding controller 44 is precisely aligned with the pivot 43; S4. Slightly lift the pivot 43 to disengage the sliding connector 42 from the right-angle guide rail 41; S5. Apply gentle force to rotate the auxiliary table 30 90 degrees around the pivot 43; S6. After rotation, slide the auxiliary table 30 to the desired position in the new direction; S7. The pivot 43 is reset, and the sliding connector 42 enters the right-angle guide rail 41 on the new side; S8. Relock the sliding controller 44 to complete the direction conversion.

[0057] This design allows for flexible switching of the auxiliary table 30 between the X and Y axes, greatly enhancing the versatility and adaptability of the worktable. It not only allows users to adjust the position of the auxiliary table according to workpieces of different sizes or specific operational needs, but also easily handles complex scenarios requiring changes in working direction.

[0058] In some embodiments, the auxiliary platform 30 is provided with a folding support assembly 31, which is installed on the side of the bottom surface of the auxiliary platform 30 away from the sliding connector 42. The folding support assembly 31 adopts a foldable structure design, which can be folded away when not in use to reduce space occupation. Furthermore, the folding support assembly 31 is equipped with foldable swivel casters to participate in support and steering in scenarios where the auxiliary platform 30 is heavy. These swivel casters can rotate freely 360 degrees when unfolded, improving the mobility and flexibility of the auxiliary platform. When the auxiliary platform 30 is carrying heavy objects, the folding support assembly 31 can be unfolded to share the weight with the sliding connector 42, enhancing overall stability. At the same time, the design of the swivel casters makes it easy to move and adjust the position of the auxiliary platform 30 even under load. When no additional support is needed, the folding support assembly 31 can be easily folded away, maintaining the simple appearance and space efficiency of the auxiliary platform 30.

[0059] Example 2: To further optimize the flip-and-fold storage function, this invention employs an innovative sliding engagement structure in some embodiments. See also Figure 7 The sliding fit between the right-angle guide rail 41 and the sliding connector 42 adopts an arc-shaped surface contact design, and the specific structure is as follows: 1. Right-angle guide rail 41: A concave arc surface 411 is designed on its upper surface. The concave arc surface 411 extends along the length of the guide rail to form a continuous arc track.

[0060] II. Sliding Connector 42: Composed of two main parts: a convex arc surface 421 and a connecting plate surface 422. The convex arc surface 421: Its curvature matches the concave arc surface 411 of the right-angle guide rail 41, ensuring smooth sliding between the two. The connecting plate 422: One end is fixedly connected to the convex arc surface 421, and the other end is fixedly connected to the bottom surface of the auxiliary platform 30. The thickness of the end connected to the convex arc surface 421 is less than the diameter of the convex arc surface 421.

[0061] Installation configuration: A certain distance is maintained between the convex arc surface 421 and the bottom surface of the auxiliary tabletop 30. This distance serves as clearance when the auxiliary tabletop 30 is flipped over for storage.

[0062] Its functional features include: Sliding function: The arc-shaped surface design allows the sliding connector 42 to slide smoothly on the right-angle guide rail 41, enabling position adjustment of the auxiliary platform 30. Flipping function: The arc-shaped surface structure allows the auxiliary platform 30 to flip around the axis of the sliding connector 42 for easy storage. Self-locking effect: Within a certain angle range, the contact of the arc-shaped surface provides a certain self-locking effect, increasing stability during use.

[0063] Example 3: To further improve the stability of sliding and adjustment, the present invention introduces additional structural designs in some embodiments. See also Figure 2-1 , Figure 7 The specific improvements are as follows: 1. Guide arc surface 412: Location: Set above the concave arc surface 411.

[0064] Shape: The cross-section is arc-shaped, partially covering the concave arc surface 411.

[0065] Function: Provides additional guidance and stabilization when the auxiliary platform 30 moves.

[0066] II. Optimized design of the sliding controller 44: Installation location: redesigned so that its guide surface 01 falls exactly on the guide arc surface 412.

[0067] Structural adjustment: The guide surface 01 is designed to match the shape of the guide arc surface 412.

[0068] Working principle: a. Slip stability: When the auxiliary platform 30 moves, the convex arc surface 421 of the sliding connector 42 slides on the concave arc surface 411. Simultaneously, the guide surface of the sliding controller 44 slides on the guide arc surface 412. This dual contact provides better motion stability and accuracy.

[0069] b. Location locking mechanism: Locking operation: Operate the sliding controller 44 to make its guide surface 01 press downward against the guide arc surface 412.

[0070] Locking effect: The sliding controller 44 and the two sliding connectors 42 work together to form a three-point lock.

[0071] Advantages: Disperses locking force, improves stability, and reduces single-point wear.

[0072] Design advantages: Improved stability: The dual-guide structure significantly enhances the stability of the auxiliary platform 30 during movement.

[0073] Simplified locking operation: Fast and reliable locking can be achieved simply by operating the slide controller 44.

[0074] Uniform force distribution: The three-point locking mechanism ensures that the auxiliary platform 30 is subjected to uniform force when locked.

[0075] Reduced wear: By distributing contact points, single-point wear is reduced, extending component life.

[0076] Precise operation: The improved guidance system allows for more precise position adjustments.

[0077] Potential applications: This design is particularly suitable for working environments that require frequent adjustments and high-precision positioning.

[0078] This design can provide better stability under operating conditions with greater vibration.

[0079] III. Space-saving design for auxiliary countertops when flipped up for storage: Reference Figure 7 , Figure 8 Two clearance notches 03 are made on the right-angle guide rail 41. The distance between the two clearance notches 03 is the same as the distance between the two sliding connectors 42. The width of the clearance notches 03 is slightly larger than the width of the sliding connectors 42.

[0080] Furthermore, a center hole 04 is made on the convex arc surface 421, and a flip pin 05 is installed at the end of the right-angle guide rail 41. The flip pin 05 is coaxial with the concave arc surface 411 and its free end faces the center. The flip pin 05 is used to cooperate with the center hole 04 to improve the flipping stability of the auxiliary table 30.

[0081] Example 4: Building upon embodiments 1-3, this embodiment aims to provide a mechanical locking mechanism that does not require continuous power support, adapting to special applications such as field operation environments, prolonged power outages, or scenarios requiring low power consumption. This design solves the problem that the pivot 43 requires a controllable lifting mechanism and typically necessitates power support.

[0082] Specifically, this embodiment designs a sliding controller 44 with an integrated mechanical locking mechanism. Combined with... Figure 4-1 , Figure 6 and Figure 6-1 The slide controller 44 includes the following components: 1) Operation part body 441: The disc is shaped like a disk with one corner vertically cut off. A pin 06 is located on the cut-off surface, and a screw hole 07 is located in the center. The operating unit body 441 is embedded in the upper surface of the auxiliary table 30. Wear-resistant alloys, such as 7075 aerospace aluminum alloy, are used to ensure long-term stability.

[0083] 2) Lower fixing component 442: Located on the lower surface of the auxiliary table 30, the operating unit body 441 is fixed to the auxiliary table 30 by bolts. It is made of high-strength stainless steel, which is corrosion-resistant and has good strength.

[0084] 3) Dual-function screw actuator 443: The main body 08 is a bolt, its threaded screw fitting into the screw hole 07. The shank of the bolt is on the upper surface of the operating part body 441, and a dual-function head 081 is fixedly mounted on the head. The dual-function head 081 includes: Locking top pressure part 082: A ring-shaped structure with a slightly larger diameter, for example, a diameter 5mm larger than the main body 08 and a thickness of 2mm.

[0085] Pushing part 083: Located below the locking and pressing part 082, it is cylindrical with the same diameter as the main body 08 and a height of 5mm. It is made of high-strength alloy steel with a hardened surface to improve wear resistance.

[0086] 4) Guide and pivot fitting 444: The shape is a disc with one corner cut off vertically. An arc-shaped protrusion 09 is provided on the cut-off surface, and the bottom is a spherical arc surface (optionally, such as a radius of curvature of 50mm). The guide surface 01 described in embodiments 1 and 3 is provided on the spherical arc surface, and the center of the guide and pivoting mating part 444 is provided with the mating hole 02 described in embodiment 1.

[0087] 5) Limiting component 445: The overall structure is a plate. One end has a waist hole 4451 that engages with pin 06; the other end has an arc-shaped groove 4452 that matches and engages with arc-shaped protrusion 09. The arc length of the arc-shaped protrusion 09 is less than that of the arc-shaped groove 4452. This design gives the guide and pivoting mating part 444 two degrees of freedom: Vertical direction: The stroke is limited by the combination of the waist hole 4451 and the pin 06. Horizontal swing: Along the extension direction of the right-angle guide rail 41, the stroke is limited by the fit between the arc groove 4452 and the arc protrusion 09. The material is an elastic alloy, such as beryllium copper alloy, which combines strength and elasticity.

[0088] 6) Elastic component 446: A compression spring design is employed, with one end resting against the lower surface of the operating part body 441 and the other end resting against the upper surface of the pivoting mating part 444. The spring material is stainless steel, and the preload is 50N to ensure the mechanism's sensitive response and stability.

[0089] 7) Improvements to Pivot 43: Designed to have vertical elasticity, it integrates a compression spring with a spring constant of 500 N / mm and a maximum compression of 10 mm. This design provides the necessary cushioning and adaptive capability when the auxiliary platform rotates 30 degrees.

[0090] 8) Improvements to avoid gap 03: The position of the clearance gap 03 along the extension direction of the right-angle guide rail 41 is optimized. Specifically: When turning, the rear sliding connector 42 rotates out from the clearance notch 03 near the pivot 43. The specific position of the clearance notch 03 is reasonably allocated according to the position of the pivot 43.

[0091] Working principle: 1. Position adjustment: When the position of the auxiliary platform 30 needs to be adjusted, the main body 08 is rotated to raise it. This releases the pressure of the locking top pressure part 082 on the guide and pivoting engagement part 444, and at the same time, the two sliding connectors 42 are released from the locked state. At this time, the auxiliary platform 30 can slide freely.

[0092] 2. Turning preparation: The freedom of design of the pivot fitting 444 and the elastic expansion and contraction capability of the pivot 43 in the vertical direction make the steering operation simple. Simply push the auxiliary platform 30 towards one side of the pivot 43 to complete the docking of the mating hole 02 with the pivot 43.

[0093] 3. Steering process: a) After docking is complete, start the redirection process.

[0094] b) The sliding connector 42 located at the front slides directly off the track.

[0095] c) When the auxiliary platform 30 rotates, the sliding connector 42 located at the rear rotates out from the corresponding clearance notch 03.

[0096] d) After completing a 90-degree rotation, the sliding connector 42, which was originally located in front, moves into the new track through another clearance notch 03.

[0097] 4. Reversal complete: Rotate the main body 08 so that the push part 083 contacts the pivot 43, and gradually disengage the pivot 43 from the mating hole 02. At this time, pushing the auxiliary table 30 will complete the reversal.

[0098] 5. Locking mechanism: Position locking is achieved by rotating the main body 08, causing the locking top pressure part 082 to press against the guide and pivot fitting 444, thereby making it in close contact with the right-angle guide rail 41. This securely locks the position of the auxiliary table 30.

[0099] This design allows for flexible adjustment, smooth steering, and secure locking of the auxiliary platform 30, adapting to various work requirements. Operation is simple and intuitive, requiring no complex external power system, making it particularly suitable for use in diverse environments.

[0100] Relationship with previous embodiments: This embodiment is fully compatible with the basic structure of embodiments 1-3, and mainly optimizes the internal mechanism of the sliding controller 44, providing a locking solution that does not require continuous power. It can directly replace the sliding controller in the previous embodiments without requiring significant modifications to the overall structure.

[0101] Through this design, Embodiment 4 provides a more flexible and adaptable workbench solution, which is particularly suitable for use in various complex environments.

[0102] The above are merely specific embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in the present invention, and these should all be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
