Description

Technical Field

[0001] This utility model relates to the technical field of steel structure assembly equipment, and in particular to a steel structure assembly workbench with adjustable height. Background Technology

[0002] Steel structure assembly workbenches are indispensable basic equipment in steel structure manufacturing and building construction. They are mainly used to support and fix steel pipes, structural steel and other components to be processed, so that operators can perform welding, cutting or assembly operations.

[0003] In actual assembly operations, the different heights of operators and the varying sizes and shapes of the workpieces all necessitate different working height requirements for the workbench. A suitable working height is crucial for ensuring processing accuracy, improving work efficiency, and reducing the labor intensity of operators.

[0004] Currently, existing steel structure assembly workbenches have significant shortcomings in height adjustment. Some workbenches have a completely fixed height, unable to adapt to changing operational needs. Others, while offering adjustment functions, often rely on manual cranks or pin holes for positioning. When the workbench bears heavy steel structure workpieces, manual height adjustment is not only extremely laborious and inefficient, but also makes it difficult to ensure that the multiple legs of the workbench rise and fall synchronously, easily causing the platform to tilt. This affects stability, poses safety hazards, and lacks the necessary convenience.

[0005] Therefore, this utility model proposes a steel structure assembly workbench with adjustable height to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the steel structure assembly workbench, such as cumbersome and laborious height adjustment process, low efficiency, difficulty in ensuring smooth lifting, and lack of convenient clamping and waste collection functions integrated with the platform, this utility model aims to provide a steel structure assembly workbench with improved structure that can effectively solve the above problems and is easy to adjust in height.

[0007] This utility model provides a steel structure assembly workbench with adjustable height, comprising: a platform, and a shell fixedly connected to the bottom of the platform; the workbench also includes a height adjustment component disposed inside.

[0008] The height adjustment component is the core component for achieving automated and smooth lifting. It includes at least two sliders, a bidirectional threaded rod rotatably disposed within the housing, a motor, and at least two support legs.

[0009] Furthermore, a slide rail is provided on the inner wall of the outer shell for the slider to slide. The two ends of the bidirectional threaded rod have threads with opposite directions of rotation and are threadedly engaged with the two sliders respectively. The output end of the motor is fixedly connected to the bidirectional threaded rod to provide driving force. The upper end of the support leg is rotatably connected to the bottom of the platform, and its lower end is rotatably connected to the outer shell. The middle part of each support leg is rotatably connected to its corresponding slider through a hinge mechanism consisting of a connecting block and a pivot pin. Through this ingenious combination of linkage structures, the horizontal reciprocating motion of the slider is efficiently converted into the vertical lifting motion of the entire platform.

[0010] Preferably, in order to make the sliding fit between the slider and the slide rail more stable and smooth, the slider is provided with a groove that matches the shape and size of the slide rail.

[0011] Preferably, the workbench further includes a clamping assembly for clamping the workpiece. A bracket and a fixing plate are fixedly connected to the upper surface of the platform. The clamping assembly includes a steel pipe placed on the platform and adjacent to the fixing plate, a first electric push rod vertically mounted on the bracket, and a pressure plate connected to the output end of the first electric push rod and located above the steel pipe. This structure is used to achieve vertical clamping of the steel pipe.

[0012] Preferably, in order to achieve horizontal positioning and clamping of the workpiece, a side block is fixedly connected to the upper surface of the platform. The clamping assembly also includes a second electric push rod horizontally installed on the side block and a push plate connected to the output end of the second electric push rod. The push plate is located on the side of the steel pipe away from the fixed plate. By extending and retracting, the steel pipe can be horizontally pushed and pressed against the fixed plate, thereby cooperating with the pressure plate to complete the bidirectional fixation of the steel pipe.

[0013] Preferably, in order to facilitate the collection of welding waste or metal shavings generated during the operation, the platform is provided with a waste port that extends through its thickness.

[0014] Preferably, the workbench also includes a collection component detachably installed at the bottom of the platform, which is located directly below the waste inlet to receive and centrally store materials falling from the waste inlet, thus maintaining a clean working environment.

[0015] Preferably, in order to achieve quick assembly and disassembly of the collection component, the collection component includes a residue bin with a T-slot correspondingly provided at the bottom of the platform, and a T-block fixed at the top of the residue bin that can slide and engage with the T-slot. Through this sliding rail connection, the residue bin can be easily pulled out or pushed in for installation.

[0016] Preferably, in order to make it easier and more convenient for users to pull out or move the waste bin filled with waste, a handle for easy gripping is fixedly connected to the outer wall of the waste bin.

[0017] Preferably, in order to prevent the residue bin from accidentally sliding out during operation due to vibration or other reasons, the collection assembly also includes a side plate, which is detachably fixed between the platform and the residue bin by hexagonal bolts, providing reliable limiting and locking for the residue bin.

[0018] This utility model has the following beneficial effects:

[0019] 1. This utility model, by setting up a linkage-type height adjustment component consisting of a motor, a bidirectional threaded rod, a slider, support legs, connecting blocks, and pivot pins, converts the rotational motion of the motor into the vertical lifting motion of the entire platform, solving the problem of cumbersome, time-consuming, and labor-intensive process of fixing or adjusting the height of the worktable in the prior art, and achieving the technical effects of automated lifting, convenient adjustment, stable operation, and labor saving.

[0020] 2. This utility model, by setting up a pressure plate driven by a first electric push rod and a push plate driven by a second electric push rod, in coordination with a fixing plate, realizes the vertical clamping and horizontal pushing positioning of steel pipe workpieces, solving the problems of inconvenient clamping and unstable fixing of irregular workpieces in the prior art, and achieving the technical effects of automated clamping, accurate positioning, and stable and reliable clamping.

[0021] 3. This utility model solves the problem of welding residue and waste being scattered everywhere, polluting the environment, and difficult to clean in the prior art by opening a waste inlet on the platform and setting a pull-out residue box at the bottom of the platform using a T-slot and a T-block sliding fit, and supplemented by a handle and hexagonal bolts. It achieves the technical effect of automatic waste collection, keeping the environment clean, and making the residue box easy and quick to clean. Attached Figure Description

[0030] 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.

[0031] Please refer to Figures 1 to 6 This utility model provides a steel structure assembly workbench with adjustable height, which aims to solve the problems of cumbersome and laborious fixed or adjustable height of steel structure assembly workbench in the prior art, inconvenient workpiece clamping, and difficulty in cleaning welding residue.

[0032] like Figure 1 , Figure 3 and Figure 4 As shown, the height-adjustable steel structure assembly workbench includes a platform 1, with a housing 401 fixedly connected to the bottom of the platform 1. The platform 1 is used to support the workpiece and serves as the mounting base for the entire device. The workbench also includes a height adjustment component 4, which includes at least two sliders 404. A slide rail 403 is provided on the inner wall of the housing 401, and the sliders 404 are slidably mounted on the slide rail 403. Please refer to... Figure 4The slider 404 has a groove 408, and the slide rail 403 slides in cooperation with the groove 408. The height adjustment assembly 4 also includes a bidirectional threaded rod 405 rotatably disposed in the housing 401. The two ends of the bidirectional threaded rod 405 have opposite threads and are threaded in cooperation with the two sliders 404 respectively. The height adjustment assembly 4 also includes a motor 409, the output end of which is fixedly connected to the bidirectional threaded rod 405. The height adjustment assembly 4 also includes at least two support legs 402. The upper end of each support leg 402 is rotatably connected to the bottom of the platform 1, and the lower end of each support leg 402 is rotatably connected to the housing 401. The middle part of each support leg 402 is rotatably connected to its corresponding slider 404 through a hinge mechanism. The hinge mechanism includes a connecting block 407 and a pivot pin 406.

[0033] To solve the above-mentioned technical problems, the technical solution of this embodiment is that the steel structure assembly workbench with adjustable height is also provided with a structure for clamping the workpiece on the upper surface of the platform 1.

[0034] Please refer to the following carefully. Figure 1 and Figure 2 The clamping structure will be described in detail below:

[0035] A bracket 3 and a fixing plate 12 are fixedly connected to the upper surface of platform 1. The steel pipe 2 is placed on platform 1 and adjacent to the fixing plate 12. The clamping structure includes a first electric push rod 7 and a pressure plate 8. The first electric push rod 7 is vertically installed on the bracket 3. The pressure plate 8 is connected to the output end of the first electric push rod 7 and is located above the steel pipe 2 for vertically clamping the steel pipe 2. The clamping structure also includes a side block 9, a second electric push rod 10, and a push plate 11. The side block 9 is fixedly connected to the upper surface of platform 1. The second electric push rod 10 is horizontally installed on the side block 9. The push plate 11 is connected to the output end of the second electric push rod 10 and is located on the side of the steel pipe 2 away from the fixing plate 12 for horizontally pushing the steel pipe 2 to abut against the fixing plate 12. Through the coordinated work of the first electric push rod 7 and the second electric push rod 10, reliable fixation of the steel pipe 2 in both vertical and horizontal directions is achieved.

[0036] Based on the above embodiments, the present invention may further include the following preferred technical solutions:

[0037] Please refer to Figure 1 , Figure 5 and Figure 6To facilitate centralized processing of waste generated during operations, platform 1 has a waste inlet 6 extending through its thickness. The workbench also includes a collection component 5 detachably installed at the bottom of platform 1. The collection component 5 is located directly below the waste inlet 6 to receive materials. The collection component 5 includes a residue box 501. To facilitate easy assembly and disassembly of the residue box 501, a T-slot 505 is provided at the bottom of platform 1. A T-block 506 is fixed to the top of the residue box 501, and the T-block 506 slides within the T-slot 505. Furthermore, to facilitate pulling, a handle 502 is fixedly connected to the outer wall of the residue box 501. To prevent the residue box 501 from accidentally sliding out during use, the collection component 5 also includes a side plate 503. The side plate 503 is detachably fixed between platform 1 and residue box 501 by hexagonal bolts 504 to limit and fix the residue box 501.

[0038] The working principle of this utility model of a height-adjustable steel structure assembly workbench is as follows:

[0039] When the height of the worktable needs to be adjusted, the motor 409 is started. The output end of the motor 409 drives the bidirectional threaded rod 405 to rotate. Since the two ends of the bidirectional threaded rod 405 have opposite threads and are threadedly engaged with the two sliders 404 respectively, when it rotates, it will drive the two sliders 404 to move horizontally in opposite directions along the slide rail 403 on the inner wall of the outer shell 401. The horizontal movement of the sliders 404 pushes the support leg 402, which is rotatably connected to its middle part, to swing through the hinge mechanism including the connecting block 407 and the pivot pin 406. Since the upper end of the support leg 402 is rotatably connected to the bottom of the platform 1 and the lower end is rotatably connected to the outer shell 401, the swinging motion of the support leg 402 is converted into a smooth vertical lifting motion of the entire platform 1, thereby realizing the height adjustment.

[0040] When assembling the steel structure, the steel pipe 2 is placed on the platform 1 near the fixed plate 12. The second electric push rod 10, which is horizontally mounted on the side block 9, is activated. The second electric push rod 10 pushes the push plate 11, pushing the steel pipe 2 horizontally and firmly against the fixed plate 12. Then, the first electric push rod 7, which is vertically mounted on the bracket 3, is activated. The first electric push rod 7 drives the pressure plate 8 to move downward, firmly pressing the steel pipe 2 below it onto the upper surface of the platform 1. Through the synergistic action of the push plate 11 and the pressure plate 8, the steel pipe 2 is reliably fixed in both horizontal and vertical directions, facilitating subsequent welding operations.

[0041] During the operation, welding slag and waste are generated and fall through the waste inlet 6 on the platform 1, which is 6 through its thickness, and enter the collection component 5 located directly below the waste inlet 6. They are eventually collected in the slag box 501. When the slag box 501 is full and needs to be cleaned, first loosen the hexagonal bolts 504 used for fixing and remove the side plate 503. Then, hold the handle 502 on the outer wall of the slag box 501 and use the sliding engagement between the T-shaped block 506 at the top of the slag box 501 and the T-shaped groove 505 at the bottom of the platform 1 to pull the slag box 501 out smoothly for dumping. After cleaning, push it back in and fix it with the side plate 503 and hexagonal bolts 504.

[0042] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
