Description

Technical Field

[0001] This utility model relates to the field of automotive parts assembly equipment technology, specifically a multi-functional worktable that can be raised, lowered, and rotated. Background Technology

[0002] In automotive parts assembly, the workbench serves as the core operating platform, and its performance directly impacts assembly accuracy, efficiency, and worker workload. Traditional workbenches used in the industry suffer from numerous technical bottlenecks, failing to meet the ever-increasing assembly demands of the automotive manufacturing industry. Most traditional automotive parts assembly workbenches employ a fixed structure or are only equipped with simple screw adjustments and shim stacking. This design struggles to accurately adapt to the assembly height requirements of different vehicle models. Fixed-height workbenches force workers to frequently bend over or stand on tiptoe, reducing assembly efficiency and potentially leading to occupational health problems such as lumbar muscle strain with prolonged use. The lack of angle adjustment functionality is another major shortcoming of traditional workbenches. Automotive parts assembly involves numerous multi-angle and multi-directional operations, such as the snapping and installation of mechanical parts. However, with traditional workbench surfaces fixed horizontally, workers can only find suitable angles by constantly adjusting their position or manually flipping the workpiece. This not only increases worker workload but can also cause scratches and deformation of parts due to repeated flipping, affecting product quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a multifunctional worktable that can be raised, lowered, and rotated to solve the problems of difficulty in height adjustment and lack of angle adjustment function in existing technologies.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-functional workbench with adjustable height and rotation angle, including a base, with first hinges at the four corners of the base, and support legs on the base. The lower ends of the support legs are movably connected to the base through the first hinges, and a support frame is provided at the upper end of the support legs. The support frame includes a base plate, a support rod, and a support frame. Second hinges are provided at the four corners of the bottom of the base plate, and the upper ends of the support legs are movably connected to the support frame through the second hinges. A workbench is provided at the upper end of the support frame.

[0005] A third hinge is provided on one side of the first hinge on the base. One end of the hydraulic rod is movably connected to the base through the third hinge. A fourth hinge is provided on the upper end of the support leg on the side corresponding to the third hinge. The other end of the hydraulic rod is movably connected to the support leg through the fourth hinge.

[0006] Preferably, a first support column is provided at the middle of the upper end of the base plate of the support frame, a first connecting column is provided at the upper end of the first support column, the first connecting column and the first support column are rotatably connected, a first gear is provided on the outer periphery of the first connecting column, and the top of the first connecting column is fixedly connected to the worktable.

[0007] On the upper part of the base plate of the support frame, a second connecting column is provided on one side of the first support column, and a second support column is provided on the upper end of the second connecting column. The second support column and the second connecting column are rotatably connected. A handwheel is fixedly connected to the second support column, and a second gear is provided on the outer periphery of the upper end of the second support column. The first gear and the second gear are connected by chain drive.

[0008] Preferably, a slide rail is provided between the support frame of the support frame and the worktable.

[0009] Preferably, the bottom of the first support column is provided with a first fixing plate, the first fixing plate is provided with a plurality of first fixing holes, and the first fixing plate is detachably connected to the base plate through the first fixing holes;

[0010] The bottom of the second connecting column is provided with a second fixing plate, and the second fixing plate is provided with multiple second fixing holes. The second fixing plate is detachably connected to the base plate through the second fixing holes.

[0011] Preferably, the worktable is engraved with scale lines.

[0012] Compared with the prior art, the present invention provides the following beneficial effects:

[0013] By installing a hydraulic rod on the base that is movably connected to the support leg, one end of the hydraulic rod is connected to the base via a third hinge, and the other end is connected to the support leg via a fourth hinge, thus realizing flexible adjustment of the workbench height.

[0014] The worktable's rotation function is achieved by utilizing a transmission structure consisting of a first gear, a second gear, and a chain on the support frame, along with a handwheel connected to the second gear. During multi-angle assembly of automotive parts, the operator only needs to turn the handwheel, which drives the first and second gears via the chain, to rotate the worktable, fixed to the first connecting column, to the desired angle. This eliminates the need for frequent workpiece or personnel repositioning. Furthermore, the scale lines on the worktable assist in accurately positioning the rotation angle, further improving assembly precision.

[0015] The slide rails installed between the support frame and the worktable provide stable support and guidance for the rotation of the worktable. During the rotation of the worktable, the slide rails slide smoothly along the guide rails, effectively distributing the weight of the worktable and the workpiece, reducing the swaying and friction of the rotating parts, making the rotation of the worktable smoother and more fluid. At the same time, it enhances the stability during the rotation process and avoids assembly errors caused by swaying. Especially when assembling precision automotive parts, it can ensure the accuracy and reliability of the operation.

[0016] Furthermore, the first fixing plate at the bottom of the first support column and the second fixing plate at the bottom of the second connecting column are detachably connected to the base plate via first fixing holes and second fixing holes, respectively. The hinged design of the support legs to the base and support frame also contributes to the modularity of this workbench. When a component is damaged or requires functional expansion according to production needs, the corresponding module can be quickly disassembled and replaced, significantly reducing maintenance and time costs. Simultaneously, the modular structure facilitates equipment transportation and installation, allowing assembly without specialized tools and personnel, greatly improving the flexibility and convenience of equipment use.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides a technical solution: a multi-functional workbench with adjustable height and rotation angle, including a base 1, with first hinges 201 at the four corners of the base 1, and support legs 2 on the base 1. The lower end of the support legs 2 is movably connected to the base 1 through the first hinges 201, and a support frame 4 is provided at the upper end of the support legs 2. The support frame 4 includes a base plate 401, a support rod 402, and a support frame 403. The bottom four corners of the base plate 401 are provided with second hinges 202, and the upper end of the support legs 2 is movably connected to the support frame 4 through the second hinges 202. A workbench 5 is provided at the upper end of the support frame 4.

[0023] A third hinge 301 is provided on one side of the first hinge 201 on the base 1. One end of the hydraulic rod 3 is movably connected to the base 1 through the third hinge 301. A fourth hinge 302 is provided on the upper end of the support leg 2 on the side corresponding to the third hinge 301. The other end of the hydraulic rod 3 is movably connected to the support leg 2 through the fourth hinge 302.

[0024] Through the above technical solution, a first hinge 201 and a third hinge 301 are provided on the base 1, a fourth hinge 302 is provided on the support leg 2, and a second hinge 202 is provided at the bottom of the base plate 401. The lower end of the support leg 2 is movably connected to the base 1 through the first hinge 201, and the upper end is movably connected to the support frame 4 through the second hinge 202. At the same time, one end of the hydraulic rod 3 is connected to the base 1 through the third hinge 301, and the other end is connected to the support leg 2 through the fourth hinge 302, realizing the flexible lifting and lowering of the worktable 5. Among them, the hydraulic rod 3 is a mature existing technology, and its extension and retraction can be achieved through the operating panel or other control devices. Its specific driving details will not be described here.

[0025] When the hydraulic rods 3 extend, the four hydraulic rods 3 simultaneously push the four support legs 2 to tilt outward with the first hinge 201 as the fulcrum. Since the upper end of the support leg 2 is movably connected to the support frame 4 through the second hinge 202, the support frame 4 will be raised accordingly, thereby driving the worktable 5 to rise. When the hydraulic rods 3 retract, under the action of gravity, the support legs 2 retract inward and rotate in the opposite direction with the first hinge 201 as the fulcrum, and the support frame 4 and the worktable 5 descend.

[0026] This utility model provides a technical solution: a first support column 13 is provided in the middle of the upper end of the base plate 401 of the support frame 4, a first connecting column 14 is provided at the upper end of the first support column 13, the first connecting column 14 is rotatably connected to the first support column 13, a first gear 11 is provided on the outer periphery of the first connecting column 14, and the top of the first connecting column 14 is fixedly connected to the workbench 5.

[0027] On the upper end of the base plate 401 of the support frame 4, a second connecting column 18 is provided on one side of the first support column 13, and a second support column 17 is provided on the upper end of the second connecting column 18. The second support column 17 and the second connecting column 18 are rotatably connected. A handwheel 6 is fixedly connected to the second support column 17. A second gear 12 is provided on the outer periphery of the upper end of the second support column 17. The first gear 11 and the second gear 12 are connected by a chain 10.

[0028] A slide rail 9 is provided between the support frame 403 of the support frame 4 and the workbench 5;

[0029] The workbench 5 is engraved with scale lines 501.

[0030] Through the above technical solution, a first support column 13 and a second connecting column 18 are set on the base plate 401 of the support frame 4. The first connecting column 14 on the first support column 13 is fixedly connected to the worktable 5. The second support column 17 on the second connecting column 18 is driven by a handwheel 6. A first gear 11 is set on the first connecting column 14, and a second gear 12 is set on the second support column 17. The first gear 11 and the second gear 12 are connected by a chain 10, realizing the rotation function of the worktable 5. When the operator turns the handwheel 6, the second support column 17 drives the second gear 12 to rotate, and the power is transmitted to the first gear 11 through the chain 10, so that the worktable 5 fixed to the first connecting column 14 rotates around the axis of the first support column 13. Compared with the traditional electric rotating mechanism, this gear-chain transmission structure has the advantages of simple operation, low cost, and simple maintenance. It can also achieve arbitrary angle adjustment of the worktable 5 through manual control, meeting the multi-angle assembly requirements of automotive parts.

[0031] The slide rail 9 provided between the support frame 403 of the support frame 4 and the worktable 5 has its guide rail fixedly connected to the upper end of the support frame 403 and the slide rail 9 fixedly connected to the bottom of the worktable 5, providing a stable support and guiding structure for the rotation of the worktable 5.

[0032] The scale line 501 engraved on the worktable 5 provides a precise reference for the rotation angle of the worktable 5. When the operator turns the handwheel 6 to adjust the angle of the worktable 5, the rotation angle can be read visually through the scale line 501, ensuring the accuracy of the angle of the worktable 5 during the assembly process.

[0033] This utility model provides a technical solution: a first fixing plate 15 is provided at the bottom of the first support column 13, and a plurality of first fixing holes 16 are provided on the first fixing plate 15. The first fixing plate 15 is detachably connected to the base plate 401 through the first fixing holes 16.

[0034] The bottom of the second connecting column 18 is provided with a second fixing plate 19, and the second fixing plate 19 is provided with a plurality of second fixing holes 20. The second fixing plate 19 is detachably connected to the base plate 401 through the second fixing holes 20.

[0035] Through the above technical solution, a first fixing plate 15 is provided at the bottom of the first support column 13, and a second fixing plate 19 is provided at the bottom of the second connecting column 18. The two fixing plates are detachably connected to the base plate 401 through the first fixing hole 16 and the second fixing hole 20, respectively, realizing the modular design of the core components of the workbench 5. When it is necessary to repair or replace the first support column 13 and the second connecting column 18, it is only necessary to remove the bolts or other connecting parts in the fixing holes to separate the corresponding components from the base plate 401.

[0036] Working Principle: When the height of the worktable 5 needs to be adjusted, the operator activates the hydraulic rod 3 via the control panel or other control device. One end of the hydraulic rod 3 is movably connected to the base 1 via the third hinge 301, and the other end is connected to the support leg 2 via the fourth hinge 302. As the hydraulic rod 3 extends, it pushes the support leg 2 to tilt outward with the first hinge 201 on the base 1 as the fulcrum. Since the upper end of the support leg 2 is movably connected to the base plate 401 of the support frame 4 via the second hinge 202, the support frame 4 will be raised accordingly, thereby driving the worktable 5 fixed on the upper end of the support frame 4 to rise synchronously. Conversely, when the hydraulic rod 3 retracts, under the action of gravity, the support leg 2 retracts inward and rotates in the opposite direction with the first hinge 201 as the fulcrum, so that the support frame 4 and the worktable 5 descend smoothly. By controlling the extension and retraction of the hydraulic rod 3, the worktable 5 can be precisely adjusted to a suitable height to meet the needs of different assembly stations and operators.

[0037] During multi-angle assembly of automotive parts, the operator turns handwheel 6, causing the second support column 17, which is fixedly connected to handwheel 6, to rotate accordingly. The second support column 17 is rotatably connected to the second connecting column 18, and the second gear 12 on the outer periphery of the upper end of the second support column 17 is connected to the first gear 11 via chain 10. When the second gear 12 rotates, it transmits power to the first gear 11 through chain 10. Since the first gear 11 is fixedly sleeved on the outer periphery of the first connecting column 14 connected to the worktable 5, and the first connecting column 14 is rotatably connected to the first support column 13, the first gear 11 drives the first connecting column 14 and the worktable 5 to rotate around the axis of the first support column 13. The scale lines 501 engraved on the worktable 5 assist the operator in visually reading the rotation angle, achieving precise positioning, and ensuring the accuracy of the assembly angle.

[0038] During the rotation of the worktable 5, the slide rail 9 between the support frame 403 and the worktable 5 plays a crucial role. The guide rail of the slide rail 9 is fixedly installed on the upper end of the support frame 403, and the slide rail 9 is fixedly connected to the bottom of the worktable 5. The slide rail 9 slides smoothly along the guide rail, which can effectively distribute the weight of the worktable 5 and the workpiece, reduce the shaking and friction generated during rotation, ensure that the worktable 5 rotates smoothly and stably, avoid assembly errors caused by shaking, and improve the accuracy and reliability of assembly operations;

[0039] When components of the workbench 5 are damaged or require functional upgrades, the first fixing plate 15 at the bottom of the first support column 13 and the second fixing plate 19 at the bottom of the second connecting column 18 come into play. The first fixing plate 15 is detachably connected to the base plate 401 through multiple first fixing holes 16, and the second fixing plate 19 is detachably connected to the base plate 401 through multiple second fixing holes 20. Maintenance personnel only need to remove the connecting bolts and other components in the fixing holes to separate the first support column 13 and the second connecting column 18 from the base plate 401 for individual repair or replacement, quickly and conveniently completing equipment maintenance and upgrades, and reducing maintenance costs.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
