Description

Technical Field

[0001] This application relates to the technical field of auxiliary tooling for welding, and in particular to an auxiliary tooling for welding that is easy to disassemble. Background Technology

[0002] Welding is a process that uses heat or pressure, or both, to permanently join two separate metal workpieces together by forming an atomic bond. During welding, auxiliary tooling is usually required to position, fix, support, and clamp the workpieces.

[0003] In the field of welding, especially when welding long rod-shaped objects, such as welding metal bench legs, it is necessary to weld the end of one long rod to the outer surface of another long rod. The accuracy of the welding angle and the stability of the weldment are extremely critical. Auxiliary tooling is required to fix the weldment, ensure that it is welded at the designed angle, and firmly fix the weldment during welding to avoid shaking, which greatly improves welding quality and production efficiency.

[0004] Most common welding fixtures are designed for conventional vertical angle welding, and can usually only meet the requirements of 90-degree angle welding. When special angle welding is required, such as when making furniture with unique shapes, it is necessary to weld bench legs to crossbars at non-standard angles such as 30° or 45°. Operators often need to spend a lot of time to make major modifications to the fixtures or replace the fixtures, which greatly delays the production schedule and increases the production cost. Therefore, we propose an auxiliary welding fixture that is easy to disassemble. Utility Model Content

[0005] To address the problem of existing welding angle adjustment difficulties, this application provides an auxiliary welding fixture that is easy to disassemble.

[0006] The welding auxiliary tooling provided in this application, which is easy to disassemble, adopts the following technical solution:

[0007] A welding auxiliary fixture that is easy to disassemble includes a base plate. A rotatable rotating plate is provided on the upper surface of the base plate. The rotating plate is used to fix a transverse weldment. A support plate with a semi-circular ring structure is fixedly connected to the upper surface of the rotating plate. A sliding box is slidably connected to one side of the support plate. A fixing mechanism is provided on the side of the sliding box away from the support plate. The fixing mechanism is used to fix a vertical weldment. The support plate is used to restrict the movement path of the sliding box. The angle between the transverse weldment and the vertical weldment can be adjusted by sliding the sliding box along the support plate.

[0008] Furthermore, two limiting plates are fixedly connected to the side of the sliding box away from the fixing mechanism, and a measuring rod is fixedly installed between the two limiting plates. One side of the measuring rod is slidably connected to the protractor.

[0009] Furthermore, one of the limiting plates has a fixing member bolted to its inner wall, and the other limiting plate has an elastic mechanism on its inner wall.

[0010] Furthermore, the elastic mechanism includes a limiting rod, the outer surface of which is slidably connected to a limiting plate, a fixed seat fixedly connected to the end of the limiting rod, a second spring sleeved on the outer surface of the limiting rod, one end of which is fixedly connected to the limiting plate, and the other end of which is fixedly connected to the fixed seat. A ball bearing is movably embedded in the inner wall of the fixed seat, and multiple limiting grooves are provided on the side of the support plate near the elastic mechanism.

[0011] Furthermore, the sliding box is equipped with a fine-tuning mechanism, which includes a rotating knob. The outer surface of the rotating knob is rotatably connected to the sliding box. A rotating roller is fixedly connected to the lower surface of the rotating knob. The outer surface of the rotating roller abuts against the support plate. Both the outer surface of the rotating roller and the side of the support plate near the rotating roller are provided with structures that can increase the friction between them.

[0012] Furthermore, the fixing mechanism includes a fixing plate, one side of which is fixedly connected to the sliding box, and the other side of which has a rectangular groove. A rotating rod is hinged to the outer surface of the sliding box, and the rotating rod is located inside the rectangular groove.

[0013] Furthermore, the inner wall of the fixing plate is threaded with a first threaded knob, and the end of the first threaded knob is rotatably connected to a pressing plate.

[0014] Furthermore, the base plate is provided with a rotation limiting mechanism inside, which is used to fix the rotating plate when it is rotated to different angles.

[0015] In summary, the beneficial technical effects of this application are as follows:

[0016] 1. This easily detachable welding auxiliary fixture, by setting up components such as a support plate and a sliding box, uses a rotating plate to place the horizontal weldment, and then places the vertical weldment inside the fixed mechanism. First, adjust the position of the sliding box so that the sliding box rotates around the center of the support plate. When adjusting the position of the sliding box, the position of the upper end of the vertical weldment changes, thereby changing the angle between the vertical and horizontal weldments, achieving the effect of easy angle adjustment, thus solving the existing problem of inconvenient welding angle adjustment;

[0017] 2. This easily detachable welding auxiliary fixture, through the setting of components such as the elastic mechanism, has multiple limiting grooves opened at the commonly used welding angle of the support plate. During the sliding of the sliding box, the second spring of the elastic mechanism is always in a pre-compressed state, pushing the fixed seat and the embedded ball to fit against the surface of the support plate. When sliding to the commonly used angle position, the ball is embedded into the corresponding limiting groove under the action of the second spring, producing a clear jamming feel. The commonly used angle can be quickly located without observing the protractor, improving the adjustment efficiency. Attached Figure Description

[0026] The technical solutions of this application will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0027] This application discloses an auxiliary welding fixture that is easy to disassemble. (Refer to...) Figure 1-6 It includes a base plate 1, with a rotatable rotating plate 2 on the upper surface of the base plate 1 for fixing the transverse weldment. A support plate 3 with a semi-circular structure is fixedly connected to the upper surface of the rotating plate 2. A sliding box 4 is slidably connected to one side of the support plate 3. A fixing mechanism 5 is provided on the side of the sliding box 4 away from the support plate 3 for fixing the vertical weldment. The support plate 3 restricts the movement path of the sliding box 4. By sliding the sliding box 4 along the support plate 3, the angle between the transverse and vertical weldments can be adjusted. The base plate 1 provides overall support. A slot 11 is provided in the middle of the rotating plate 2 for placing the transverse weldment. If the diameter of the transverse weldment is smaller than the slot 11... The diameter is adjusted so that the horizontal weldment is pushed close to one side of the support plate 3, and the other side is plugged with an external object to ensure the fixation of the horizontal weldment. Alternatively, bolts can be installed on the rotating plate 2 to hold the horizontal weldment in place. The vertical weldment is then placed inside the fixing mechanism 5. The position of the sliding box 4 is adjusted so that the sliding box 4 rotates around the center of the support plate 3. The side of the sliding box 4 facing the vertical weldment is aligned with the inner side of the slot 11 near the support plate 3, so that the vertical weldment and the horizontal weldment are on the same plane. When adjusting the position of the sliding box 4, the upper position of the vertical weldment is changed, thereby changing the angle between the vertical weldment and the horizontal weldment, achieving the effect of easy angle adjustment.

[0028] Two limiting plates 6 are fixedly connected to the side of the sliding box 4 away from the fixed mechanism 5. A measuring rod 8 is fixedly installed between the two limiting plates 6. One side of the measuring rod 8 is slidably connected to the protractor 9. When the sliding box 4 slides, it can drive the limiting plates 6 and the measuring rod 8 to rotate synchronously, so that the measuring rod 8 slides on the protractor 9. The protractor 9 is set with a scale. By observing the position of the measuring rod 8 on the protractor 9, the angle value formed by the vertical weldment and the horizontal weldment can be accurately obtained. It is suitable for welding methods that require very precise welding angles.

[0029] One of the limiting plates 6 has a fixing member 7 bolted to its inner wall, and the other limiting plate 6 has a spring mechanism 13 on its inner wall. The fixing member 7 is a bolt. After adjusting to the appropriate position, tightening the fixing member 7 can cause the fixing member 7 to press against the outer surface of the support plate 3, thereby fixing the position of the sliding box 4. This adopts a common fixing method. The spring mechanism 13 is used to optimize the feel during the sliding of the sliding box 4. When sliding to some commonly used angles, there is a limiting effect. When adjusting some commonly used angles, it is not necessary to accurately observe the protractor 9, thus increasing efficiency.

[0030] The elastic mechanism 13 includes a limiting rod 1301. The outer surface of the limiting rod 1301 is slidably connected to the limiting plate 6. A fixed seat 1302 is fixedly connected to the end of the limiting rod 1301. A second spring 1303 is sleeved on the outer surface of the limiting rod 1301. One end of the second spring 1303 is fixedly connected to the limiting plate 6, and the other end of the second spring 1303 is fixedly connected to the fixed seat 1302. A ball bearing 1304 is movably embedded in the inner wall of the fixed seat 1302. The support plate 3 has multiple limiting grooves 1305 on the side near the elastic mechanism 13. The limiting grooves 1305 are opened at commonly used welding angles, such as 90 degrees, 60 degrees, and 120 degrees. When the limiting plate 6 slides to the corresponding position, under the action of the second spring 1303, the ball bearing 1304 will be driven into the interior of the limiting groove 1305, thereby blocking the hand feel and facilitating positioning. At this time, the sliding box 4 can be directly fixed.

[0031] The sliding box 4 is equipped with a fine-tuning mechanism 12, which includes a rotating knob 1201. The outer surface of the rotating knob 1201 is rotatably connected to the sliding box 4. A rotating roller 1202 is fixedly connected to the lower surface of the rotating knob 1201. The outer surface of the rotating roller 1202 abuts against the support plate 3. Both the outer surface of the rotating roller 1202 and the side of the support plate 3 near the rotating roller 1202 are provided with structures that can increase the friction between the two. The position where the rotating roller 1202 contacts the support plate 3 is provided with a rough surface. When the rotating knob 1201 is turned, it can drive the rotating roller 1202 to rotate. The friction causes the sliding box 4 to move, achieving the effect of fine adjustment. In use, coarse adjustment is first performed by manual sliding, and then fine adjustment is performed by rotating the knob 1201 to increase efficiency. In another embodiment, the structure that increases the friction between the two can also be a tooth meshing relationship for easy cooperation.

[0032] The fixing mechanism 5 includes a fixing plate 501. One side of the fixing plate 501 is fixedly connected to the sliding box 4. A rectangular groove 502 is provided on the other side of the fixing plate 501. A rotating rod 503 is hinged to the outer surface of the sliding box 4. The rotating rod 503 is located inside the rectangular groove 502. The fixing plate 501 can be opened or closed by rotating the rod 503 to facilitate the handling of vertical welding parts.

[0033] The inner wall of the fixing plate 501 is threaded with a first threaded knob 504. The end of the first threaded knob 504 is rotatably connected to a pressing plate 505. By turning the first threaded knob 504, the pressing plate 505 can be driven to approach the vertical weldment to press and fix it. A similar structure can also be used at the horizontal weldment, which will not be described in detail.

[0034] The base plate 1 is internally equipped with a rotation limiting mechanism 10, which is used to fix the rotating plate 2 at different angles. During welding, the rotating plate 2 can be rotated to rotate the workpiece, thereby welding the back side. Depending on cost requirements, the rotation limiting mechanism 10 can use a simple bolt pressing and fixing structure, where the rotating plate 2 is pressed and fixed by bolts, and the bolts are loosened to release the fixing when the rotating plate 2 is rotated. Alternatively, a more convenient but slightly more expensive structure can be used. In this embodiment, the rotation limiting mechanism 10 includes a rotating disk 1001, which is fixedly connected to the lower surface of the rotating plate 2 and is located inside the base plate 1. Multiple locking holes 1003 are provided on the rotating disk 1001, and a locking mechanism is provided on the front side. A rod 1002 is slidably connected to the base plate 1. When the rod 1002 is inserted into the slot 1003, the rotating plate 2 can be fixed. A fixing ring 1004 is fixedly installed on the rod 1002. A first spring 1005 is provided between the fixing ring 1004 and the inner wall of the base plate 1. The two ends of the first spring 1005 are respectively connected to the fixing ring 1004 and the inner wall of the base plate 1. The elastic force of the first spring 1005 pushes against the fixing ring 1004, so that the rod 1002 is continuously inserted into the slot 1003. When it is necessary to rotate the rotating plate 2, the rod 1002 is pulled outward. The external rod 1002 is connected to a pull plate 1006 to facilitate pulling the rod 1002, eliminating the need for the screwing operation required by using a threaded rod. However, this embodiment has multiple structures, and in reality, it can be selected according to the needs.

[0035] The implementation principle of the welding auxiliary tooling that is easy to disassemble according to the embodiments of this application is as follows:

[0036] Place the horizontal weldment in the slot 11 in the middle of the rotating plate 2, open the rotating rod 503 that is hinged to the sliding box 4, and put the vertical weldment into the rectangular slot 502 of the fixed plate 501.

[0037] The support plate 3 adopts a semi-circular ring structure, and its arc trajectory determines the movement path of the sliding box 4. When the sliding box 4 is pushed to slide along the arc surface of the support plate 3, the fixing mechanism 5 rotates synchronously with the sliding box 4 around the center of the support plate 3, thereby changing the spatial posture of the vertical weldment. The sliding of the sliding box 4 realizes the continuous adjustment of the angle between the vertical weldment and the horizontal weldment, which meets the welding requirements of non-standard angles and conventional 90° angles.

[0038] When the sliding box 4 slides, the two limiting plates 6 fixed on its side synchronously drive the measuring rod 8 to move. The measuring rod 8 slides along the surface of the protractor 9. The protractor 9 is marked with clear angle scales. By observing the corresponding scales of the measuring rod 8 on the protractor 9, the angle between the vertical and horizontal weldments can be read in real time.

[0039] The support plate 3 has multiple limiting grooves 1305 corresponding to commonly used welding angles such as 90°, 60°, and 120°. During the sliding of the sliding box 4, the second spring 1303 of the elastic mechanism 13 is always in a pre-compressed state, pushing the fixed seat 1302 and the embedded ball 1304 to fit against the surface of the support plate 3. When sliding to the commonly used angle position, the ball 1304 is embedded in the corresponding limiting groove 1305 under the elastic force of the second spring 1303, producing a clear blocking feel. The commonly used angle can be quickly located without observing the protractor 9, improving the adjustment efficiency.

[0040] After adjusting the angle to the target value, tighten the fixing part 7 on the inner wall of one of the limiting plates 6 so that the end of the fixing part 7 is tightly pressed against the outer surface of the support plate 3. The position of the sliding box 4 is locked by friction to prevent the angle from shifting during welding. The fixing method is simple, reliable and easy to disassemble.

[0041] To meet the requirements of high-precision welding, rotating the knob 1201 drives the rotating roller 1202 to rotate, converting the rotational motion of the knob 1201 into a small displacement of the sliding box 4, thereby achieving fine adjustment of the angle. In actual operation, coarse adjustment can be completed by manual sliding first, and then calibration can be performed by fine adjustment mechanism 12, balancing adjustment efficiency and accuracy.
