Description

Technical Field

[0001] This utility model relates to the field of steel component processing technology, specifically a steel component welding fixture. Background Technology

[0002] In the field of modern industrial manufacturing, steel component welding is a key link in steel structure production and is widely used in industries such as construction, bridges, machinery manufacturing, automobiles and aerospace. With the continuous development of industrial technology, the requirements for the quality and efficiency of steel component welding are becoming increasingly stringent. As the core equipment to ensure welding accuracy and stability, the performance of steel component welding fixtures directly affects product quality and production efficiency.

[0003] When welding and clamping existing steel components, the clamps mostly use rigid clamping methods, such as bolt pressure plates and mechanical claws. This rigid clamping is prone to leaving indentations, scratches and other damage on the surface of the steel components. At the same time, for steel components of different shapes and sizes, it is often necessary to replace them with special clamps, which leads to increased clamping costs and extended production preparation cycles. Therefore, we have introduced a steel component welding clamp. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a steel component welding fixture that is adaptable to different models, provides non-marking clamping, and facilitates easy disassembly, thus solving the problems mentioned in the background art.

[0005] This utility model provides the following technical solution: a steel component welding fixture, including a working chassis, an arc-shaped groove on the inner wall of the working chassis, a turbine on the top of the working chassis, a placement platform on the top of the turbine, a slider slidably connected to the inner wall of the working chassis, an adjustment component in the inner cavity of the slider, and a non-marking clamping component on the top of the slider.

[0006] The non-marking clamping assembly includes a clamp body, an air bladder in the inner cavity of the clamp body, an air tube on the outer wall of the clamp body, a corrugated compression tube on the inner wall of the arc-shaped groove, and a one-way valve fixedly mounted on the outer wall of the corrugated compression tube.

[0008] As a preferred technical solution of this utility model: the spring is located at the bottom of the sphere, and the two ends of the outer wall of the spring are respectively connected to the inner wall of the fixed sleeve and the outer wall of the sphere. The diameter of the spring is larger than the opening diameter of the fixed sleeve. The outer wall of the fixed sleeve has the same shape as the inner wall of the arc groove two, and the outer wall of the fixed sleeve is adapted to the inner wall of the arc groove two. The helix of the worm gear is intersected and meshed with the outer edge of the turbine.

[0009] As a preferred technical solution of this utility model: the adjustment component is regarded as a movable component, and the movable component is respectively arranged on both sides of the inner wall of the slider, and the ends of the two adjustment components away from the slider are connected to the bottom of the non-marking clamping component.

[0010] As a preferred technical solution of this utility model: the outer wall of the clamp body has the same shape as the inner wall of the working chassis, and the outer wall of the clamp body is slidably fitted to the inner wall of the working chassis. There are four air bladders, and the air inlets of the four air bladders are connected to air pipes.

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

[0013] 1. This steel component welding fixture, through the coordinated transmission of an air bladder, motor, worm gear, fixture body, and corrugated compression tube, causes the fixture body and slider to move to the fixed point of the steel component. The air bladder deforms under the filling of gas, and the deformed surface clamps and fixes the steel component, thus avoiding indentations caused by rigid clamping during steel component welding. At the same time, the corrugated compression tube can also adaptively adjust the gas in the air bladder cavity under the coordinated transmission of the motor, worm gear, and slider, thereby effectively achieving non-marking and stable clamping of components of different specifications and improving the versatility of the fixture.

[0014] 2. This steel component welding fixture, through the combination of pins, springs and arc grooves, allows for easy disassembly of the non-marking clamping components and sliders by simply inserting and pulling. At the same time, if the airbag or the main body of the fixture malfunctions, it can be quickly disassembled and replaced, thereby reducing maintenance time and labor costs. It also facilitates the quick switching of the non-marking clamping components according to different production needs, thereby effectively improving equipment utilization.

[0024] 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.

[0025] Please see Figure 1 - Figure 6 A steel component welding fixture includes a working chassis 1, an arc-shaped groove 2 on the inner wall of the working chassis 1, a turbine 3 on the top of the working chassis 1, a placement platform 4 on the top of the turbine 3, a slider 5 slidably connected to the inner wall of the working chassis 1, an adjustment component 6 in the inner cavity of the slider 5, and a non-marking clamping component 7 on the top of the slider 5.

[0026] The non-marking clamping assembly 7 includes a clamp body 701, an airbag 702 in the inner cavity of the clamp body 701, an air tube 703 on the outer wall of the clamp body 701, a corrugated compression tube 704 on the inner wall of the arc groove 2, and a one-way valve 705 fixedly mounted on the outer wall of the corrugated compression tube 704.

[0027] In the above structure, by setting the non-marking clamping component 7 and the adjusting component 6, when the steel component is placed on the surface of the placement platform 4, by activating the adjusting component 6, the non-marking clamping component 7 will clamp and fix the surface of the steel component through the transmission cooperation of the adjusting component 6.

[0028] In a preferred embodiment: the adjusting component 6 includes a motor 601, a worm gear 602 is fixedly sleeved on the outer edge of the output shaft of the motor 601, a slot 603 is provided on the inner wall of the slider 5, an arc groove 604 is provided on the inner wall of the slot 603, a pin 605 is slidably connected to the inner wall of the slot 603, a fixing sleeve 606 is fixedly assembled on the inner wall of the pin 605, and a spring 607 and a ball 608 are respectively provided in the inner cavity of the fixing sleeve 606;

[0029] In a preferred embodiment: the spring 607 is located at the bottom of the sphere 608, and the two ends of the outer wall of the spring 607 overlap with the inner wall of the fixed sleeve 606 and the outer wall of the sphere 608 respectively. The diameter of the spring 607 is larger than the opening diameter of the fixed sleeve 606. The outer wall of the fixed sleeve 606 has the same shape as the inner wall of the arc groove 604, and the outer wall of the fixed sleeve 606 is adapted to the inner wall of the arc groove 604. The helix of the worm 602 intersects and meshes with the outer edge of the turbine 3.

[0030] In the above structure, the arrangement of the worm 602, the second arc groove 604, the spring 607, and the ball 608 allows the motor 601 to be started by an external power source. This causes the spiral of the worm 602 to rotate under the drive of the motor's output shaft. The rotating spiral of the worm 602 interlocks with the outer edge of the turbine 3, causing the worm 602 to drive the slider 5 to slide along the inner wall of the working chassis 1. This allows the slider 5 to extend and slide to the fixed point of the steel component. Simultaneously, when it is necessary to disassemble and replace the non-marking clamping component 7, the pin 605 is slid out along the inner wall of the slot 603, allowing the ball 608 to move along the second arc groove 604 under the drive of the pin 605. The inner wall of the 4 slides away, causing the ball 608 to move away from the inner wall of the arc groove 604. This causes the bottom spring 607 to compress and move closer to the inner wall of the fixing sleeve 606, so that the ball 608 slides into the inner cavity along the inner wall of the fixing sleeve 606. Then, the outer wall of the ball 608 will contact the inner wall of the slot 603. When the pin 605 is completely removed, the ball 608 will return to its original position under the rebound of the spring 607. The fixing sleeve 606, whose diameter opening is smaller than that of the ball 608, will fix the ball 608 to the inner wall, thus completing the separation and disassembly of the non-marking clamping component 7 from the slider 5. At the same time, the non-marking clamping component 7 can be easily installed by performing the reverse operation.

[0031] In a preferred embodiment: the adjustment component 6 is regarded as a movable component, and the movable component is respectively disposed on both sides of the inner wall of the slider 5, and the ends of the two adjustment components 6 away from the slider 5 are connected to the bottom of the non-marking clamping component 7.

[0032] In the above structure, by setting the slider 5 and the non-marking clamping component 7, when the slider 5 and the non-marking clamping component 7 need to be disassembled and connected, their connection points can be easily disassembled and removed through the two movable component adjustment components 6. At the same time, by performing the reverse operation, the slider 5 and the non-marking clamping component 7 can be quickly installed and used.

[0033] In a preferred embodiment: the outer wall of the clamp body 701 has the same shape as the inner wall of the working chassis 1, and the outer wall of the clamp body 701 is slidably fitted to the inner wall of the working chassis 1. There are four airbags 702, and the air inlets of the four airbags 702 are connected to the air pipes 703. The end of the air pipes 703 away from the four airbags 702 is connected to the air inlet of the corrugated compression pipe 704.

[0034] In the above structure, by setting up the clamp body 701, airbags 702, air pipes 703, and corrugated compression pipes 704, when the clamp body 701 moves, the corrugated compression pipes 704 are compressed. The gas inside the corrugated compression pipes 704 is compressed and transmitted through the air pipes 703 to the four airbags 702 set on the inner wall of the clamp body 701. The surface of the airbags 702 will deform, and the deformed surface will clamp and fix the surface of the steel component, thereby achieving a markless clamping of the steel component. At the same time, the airbags 702 can also be filled with gas of different sizes by the movement of the clamp body 701 and the compression of the air pipes 703, so that they can be adapted to clamp and fix steel components of different widths.

[0035] In a preferred embodiment: the turbine 3, slider 5, adjustment component 6 and non-marking clamping component 7 are regarded as a single movable component, and the movable component is respectively arranged on both sides of the inner wall of the working chassis 1.

[0036] In the above structure, by setting the turbine 3, slider 5, adjustment component 6 and non-marking clamping component 7, the movable components turbine 3, slider 5, adjustment component 6 and non-marking clamping component 7 arranged opposite to each other on both sides of the inner wall of the working chassis 1 will position and fix the two ends of the surface of the steel component when they are synchronously driven, thereby making the steel component more stable during welding.

[0037] Working principle: When in use, the steel component is placed on top of the platform 4, and then the motor 601 is started by an external power source. The spiral of the worm 602 rotates under the drive of the output shaft of the motor 601. The rotating spiral of the worm 602 interlocks with the outer edge of the turbine 3, causing the worm 602 to drive the slider 5 to slide along the inner wall of the working chassis 1. When the slider 5 extends and slides to the fixed point of the steel component, it drives the clamp body 701 to slide. At the same time, the corrugated compression pipe 704 is compressed by the sliding of the slider 5. The gas is compressed, and the compressed gas inside the corrugated compression pipe 704 is transmitted to the inner cavity of the four airbags 702 through the air pipe 703. When the clamping body 701 moves to the fixed point of the steel component, the outer wall of the four airbags 702 will deform under the filling of gas. The deformed four airbags 702 will fix and clamp the fixed point of the steel component. At the same time, the turbine 3, slider 5, adjustment component 6 and non-marking clamping component 7 on the other side of the inner cavity of the working chassis 1 can fix and clamp both ends of the steel component through the same operation.

[0038] Simultaneously, when it is necessary to repair or disassemble the non-marking clamping component 7, it is removed by sliding the pin 605 along the inner wall of the slot 603. Under the action of the pin 605, the ball 608 slides away along the inner wall of the arc groove 604. When the ball 608 is removed from the inner wall of the arc groove 604, it will drive the bottom spring 607 to compress and approach the inner wall of the fixing sleeve 606. The ball 608 will slide into the inner cavity along the inner wall of the fixing sleeve 606, and then the outer wall of the ball 608 will contact the inner wall of the slot 603. When the pin 605 is completely removed, the ball 608 will return to its original position under the rebound of the spring 607. The fixing sleeve 606, whose diameter opening is smaller than that of the ball 608, will fix the ball 608 to the inner wall, thus completing the disassembly and removal of the non-marking clamping component 7 from the slider 5. At the same time, the non-marking clamping component 7 can be easily installed by performing the reverse operation.

[0039] 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.
