Description

Technical Field

[0001] This utility model relates to the field of steel structure welding fixture technology, and in particular to a steel structure welding fixture. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. The structure is mainly composed of steel beams, steel columns, steel trusses, steel pipes and other components made of steel sections and steel plates. During the construction of steel structures, it is often necessary to weld steel beams, steel columns, steel pipes and other components.

[0003] In existing technologies, workers often place the workpiece on the ground before welding, or hold the workpiece down with one hand while operating the welding tool with the other. Both of these welding methods have the problem of unstable contact surfaces of the workpiece, which can easily lead to problems such as poor weld formation, uneven weld width, porosity, and slag inclusions in subsequent welding operations. Furthermore, they can reduce the connection strength of the welded structure, thereby affecting the overall stability of the steel structure.

[0004] Therefore, there is an urgent need to provide a steel structure welding fixture to solve the above problems. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a steel structure welding fixture.

[0006] To solve the above-mentioned technical problems, the present invention adopts a technical solution as follows: a steel structure welding fixture is provided, including a base and a hand-tightening clamping mechanism. The base is provided with an electric clamping mechanism for clamping two workpieces. The top of the electric clamping mechanism is provided with a mounting platform mechanism. The top of the mounting platform mechanism is provided with a rotation adjustment mechanism for adjusting the clamping direction.

[0007] The rotation adjustment mechanism is provided with a slide mechanism for limiting the position of the clamping part;

[0008] The slide mechanism is equipped with a hand-tightening clamping mechanism for clamping a single workpiece.

[0009] The present invention is further configured such that: the electric clamping mechanism includes a motor fixed to one end of the base, the output shaft of the motor is connected to a rotating rod, the rotating rod is provided with an external thread, and the external thread of the external thread is connected to a slider.

[0010] With the above technical solution, a groove is provided in the base to limit the movement of the slider. When the motor starts, the rotating rod will rotate, and the rotating external thread will cause the slider to move along the rotating rod.

[0011] The present invention is further configured such that: the outside of the rotating rod is provided with an external thread two, the external thread two having the opposite thread direction to the external thread one, and the external thread of the external thread two being connected to a slider two.

[0012] With the above technical solution, when the motor starts, the second external thread will also drive the second slider to move. Since the second external thread is opposite to the first external thread, when the motor rotates forward or reverses, the second slider will move towards the first slider or in the opposite direction, thereby driving the clamping component to clamp the two workpieces or release the two workpieces.

[0013] The present invention is further configured such that: the mounting platform mechanism includes a platform body fixed to the top of the slider, two limiting ears 1 are fixed to the outside of the platform body, and two limiting ears 2 are also fixed to the outside of the platform body.

[0014] Through the above technical solution, the top of the second slider is provided with the same mounting platform mechanism as the top of the first slider. The first limiting ear is fixed to both ends of the platform, the second limiting ear is fixed to the outside of the platform, and the setting direction of the second limiting ear is perpendicular to the setting direction of the first limiting ear.

[0015] The present invention is further configured such that: the rotation adjustment mechanism includes a rotating seat rotatably connected to the platform, a pin is movably disposed on the rotating seat, and a compression spring is disposed outside the pin.

[0016] With the above technical solution, one end of the compression spring is fixed to the rotating seat, and the other end of the compression spring is fixed to the pin. The user can pull out the pin, so that the pin leaves the first limiting ear, and rotate the rotating seat to put the pin into the second limiting ear. At this time, the rotating seat will rotate 90 degrees.

[0017] The present invention is further configured such that: the sliding mechanism includes a seat fixed to the top of the platform, the seat is provided with an internal threaded sleeve, and a slide rail is also fixed on the seat.

[0018] Through the above technical solution, the slide rail can limit the clamping block, thereby improving the stability of the clamping block's movement, while the internal threaded sleeve can improve the self-locking friction of the threaded torsion block and prevent the clamping block from loosening.

[0019] The present invention is further configured such that: the hand-twisting clamping mechanism includes a clamping block slidably disposed on the slide rail, a rotating connector is fixed on the clamping block, and a threaded torsion block is fixed at the other end of the rotating connector.

[0020] Through the above technical solution, the rotating connector allows the threaded torsion block and the clamping block to rotate relative to each other. When the user screws the threaded torsion block, the clamping block will move along the slide rail. When the user screws the two opposing hand-cranked clamping mechanisms, the two clamping blocks can clamp or release the workpiece. The user can also change the orientation of the hand-cranked clamping mechanism by rotating the adjustment mechanism, so that the device can clamp the workpiece in various postures, thus making the device suitable for various welding processing occasions.

[0021] The beneficial effects of this utility model are as follows:

[0022] 1. This utility model, through the setting of an electric clamping mechanism and a hand-tightening clamping mechanism, enables the device to clamp and squeeze two workpieces separately, thereby facilitating welding operations;

[0023] 2. With the inclusion of an electric clamping mechanism, a hand-tightening clamping mechanism, and a rotation adjustment mechanism, this utility model allows the user to change the orientation of the hand-tightening clamping mechanism, making the device suitable for various welding processing applications.

Detailed Implementation

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0032] Please see Figures 1-6 A steel structure welding fixture includes a base 1 and a hand-operated clamping mechanism 6. The base 1 has an internal electric clamping mechanism 2 for clamping two workpieces. The electric clamping mechanism 2 includes a motor 201 fixed to one end of the base 1. The output shaft of the motor 201 is connected to a rotating rod 202. The rotating rod 202 has an external thread 203 on its exterior. A slider 204 is connected to the external thread of the external thread 203. The rotating rod 202 also has an external thread 205 on its exterior. The external thread 205 has the opposite thread direction to the external thread 203. A slider 204 is connected to the external thread of the external thread 205. Block 206, the base 1 has a groove for limiting the movement of slider 204. When the motor 201 starts, the rotating rod 202 will rotate. At this time, the rotating external thread 203 will cause slider 204 to move along the rotating rod 202. When the motor 201 starts, the external thread 205 will also drive slider 206 to move. Since the external thread 205 and the external thread 203 are opposite in direction, when the motor 201 rotates forward or reverses, slider 206 will move towards slider 204 or in the opposite direction, thereby driving the clamping component to clamp the two workpieces or release the two workpieces.

[0033] like Figure 2 and Figure 3 As shown, the top of the electric clamping mechanism 2 is provided with a mounting platform mechanism 3. The mounting platform mechanism 3 includes a platform body 301 fixed to the top of the slider 204. Two limiting ears 302 are fixed to the outside of the platform body 301. Two limiting ears 303 are also fixed to the outside of the platform body 301. The top of the slider 206 is provided with the same mounting platform mechanism 3 as the top of the slider 204. The limiting ears 302 are fixed to both ends of the platform body 301. The limiting ears 303 are fixed to the outside of the platform body 301. The setting direction of the limiting ears 303 is perpendicular to the setting direction of the limiting ears 302.

[0034] like Figure 3 and Figure 4As shown, the top of the mounting platform mechanism 3 is provided with a rotation adjustment mechanism 4 for adjusting the clamping direction. The rotation adjustment mechanism 4 includes a rotating seat 401 rotatably connected to the platform body 301. A pin 402 is movably disposed on the rotating seat 401. A compression spring 403 is disposed on the outside of the pin 402. One end of the compression spring 403 is fixed to the rotating seat 401, and the other end of the compression spring 403 is fixed to the pin 402. The user can pull out the pin 402, so that the pin 402 is away from the first limiting ear 302, and rotate the rotating seat 401 to put the pin 402 into the second limiting ear 303. At this time, the rotating seat 401 will rotate ninety degrees.

[0035] like Figure 3 and Figure 4 As shown, the rotation adjustment mechanism 4 is provided with a slide mechanism 5 for limiting the clamping part. The slide mechanism 5 includes a seat 501 fixed to the top of the platform 301, an internal threaded sleeve 502 provided on the seat 501, and a slide rail 503 fixed on the seat 501. The slide rail 503 can limit the clamping block 601, thereby improving the stability of the movement of the clamping block 601. The internal threaded sleeve 502 can improve the self-locking friction of the threaded torsion block 603 and prevent the clamping block 601 from loosening.

[0036] like Figures 3-6 As shown, the slide mechanism 5 is equipped with a hand-tightening clamping mechanism 6 for clamping a single workpiece. The hand-tightening clamping mechanism 6 includes a clamping block 601 slidably disposed on the slide rail 503. A rotating connector 602 is fixed on the clamping block 601, and a threaded torsion block 603 is fixed at the other end of the rotating connector 602. The rotating connector 602 allows the threaded torsion block 603 and the clamping block 601 to rotate relative to each other. When the user screws the threaded torsion block 603, the clamping block 601 will move along the slide rail 503. When the user screws the two opposing hand-tightening clamping mechanisms 6, the two clamping blocks 601 can clamp or release the workpiece. The user can also change the orientation of the hand-tightening clamping mechanism 6 by rotating the adjustment mechanism 4, so that the device can clamp the workpiece in various postures, thus making the device suitable for various welding processing occasions.

[0037] When using this invention, if a worker needs to connect two workpieces, the two workpieces can be clamped by two sets of hand-cranked clamping mechanisms 6, and the electric clamping mechanism 2 can be activated. At this time, the electric clamping mechanism 2 will squeeze the two workpieces together, and the worker can perform welding at the contact point of the workpieces. When the worker needs to perform T-shaped welding on the two workpieces, one set of hand-cranked clamping mechanisms 6 can be rotated 90 degrees by rotating the adjustment mechanism 4, and one workpiece can be rotated 90 degrees and placed on the hand-cranked clamping mechanism 6. Then the electric clamping mechanism 2 can be activated. At this time, the device can clamp the two workpieces in a T-shape, which is convenient for the worker to weld. Similarly, when both sets of rotation adjustment mechanisms 4 are rotated, the device can also perform lateral welding on the two workpieces.

[0038] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
