Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary positioning devices for steel plate welding, in particular to a large steel plate welding auxiliary device. Background Technique

[0002] With the rapid development of high-tech in our country, more and more large-scale process equipment and large-scale mechanical equipment are put into production and construction. In large-scale infrastructure construction, the demand for plates is large, and the overall size of the plates is relatively large. The size of the plates processed in steel mills is usually fixed. Therefore, in actual large-scale infrastructure construction, it is usually necessary to splice and weld the plates to meet the actual needs.

[0003] During the plate splicing and welding process, an auxiliary device for steel plate welding is required to clamp and fix the steel plates, and then manual welding is carried out. However, in the existing auxiliary devices for steel plate welding, when the steel plates are assisted and fixed, it is not easy to align the steel plates, the steel plates are not fixed firmly, and displacement is likely to occur during the welding process, thus affecting the welding quality of the steel plate splicing. Content of the Utility Model

[0004] In order to solve the above technical problems, the utility model provides a large steel plate welding auxiliary device which can make the steel plates easier to align with each other, fix the steel plates more firmly, prevent displacement during the welding process, and improve the welding quality of the steel plate splicing.

[0005] Technical Solution

[0006] To achieve the above object, the present utility model provides the following technical solutions: A large steel plate welding auxiliary device, including a base, a butt joint mechanism, and a clamping mechanism. Four corners of the bottom end of the base are fixedly provided with anchor feet. The butt joint mechanism includes a motor and two groups of L-shaped support plates. The motor is fixedly installed at the right end of the base. A bidirectional threaded rod is rotatably installed on the base, and the right end of the bidirectional threaded rod is fixedly connected to the output end of the motor. Two groups of guide rods are symmetrically and fixedly provided on the base. Central parts of the bottom ends of the two groups of L-shaped support plates are fixedly connected with transmission sleeve plates. The two groups of transmission sleeve plates are symmetrically screwed and sleeved on the bidirectional threaded rod. Two groups of guide holes are provided on the two groups of transmission sleeve plates. The two groups of transmission sleeve plates are slidably sleeved on the two groups of guide rods through the cooperation of the guide holes. The two groups of L-shaped support plates are symmetrically distributed on both sides of the base. Clamping mechanisms are installed on the two groups of L-shaped support plates. The clamping mechanism includes two groups of clamping cylinders. Two groups of telescopic cylinders are symmetrically and fixedly installed at the front and rear ends of the L-shaped support plates respectively. Output ends of the two groups of telescopic cylinders at the front side and output ends of the two groups of telescopic cylinders at the rear side are fixedly connected with connecting plates. The two groups of clamping cylinders are respectively fixedly installed on the two groups of connecting plates. Output ends of the two groups of clamping cylinders are fixedly connected with L-shaped clamping plates. Bottom ends of the two groups of L-shaped clamping plates are horizontal with the top end of the L-shaped support plate. Limiting guide grooves are provided at the tops of the two groups of L-shaped clamping plates. Two groups of limiting sliders are slidably installed on the two groups of L-shaped clamping plates through the cooperation of the limiting guide grooves. Knob pressing bolts are screwed on the four groups of limiting sliders.

[0007] Preferably, support rollers are fixedly installed at four corners of the bottom ends of the two groups of L-shaped support plates, and the bottoms of the support rollers support against the top end of the base.

[0008] Preferably, two groups of T-shaped guide rods are symmetrically slidably provided on the four groups of connecting plates, and the outer side of each L-shaped clamping plate is connected to the two groups of T-shaped guide rods on each connecting plate.

[0009] Preferably, fastening rubber pads are fixedly connected to the inner walls of the outer sides of the two groups of L-shaped support plates and the vertical inner walls of the four groups of L-shaped clamping plates.

[0010] Preferably, sliding sleeves are fixedly provided in the guide holes of the two groups of transmission sleeve plates.

[0011] The beneficial effects of the present utility model compared with the prior art are as follows: When in use, according to the length of the steel plate, the telescopic cylinder is started, so that the telescopic cylinder pushes the connecting plate to move outward. The connecting plate drives the clamping cylinder and the L-shaped clamping plate to move outward, so that the steel plate can be placed on the L-shaped supporting plate. Then the steel plate is placed on the L-shaped supporting plate. The width of the L-shaped supporting plate is smaller than the width of the steel plate, so that the left end of the steel plate abuts against the left side of the L-shaped supporting plate, and the right end of the steel plate extends out of the right end of the L-shaped supporting plate. Then, by starting the clamping cylinder, the clamping cylinder is made to push the L-shaped clamping plate to move towards the steel plate, so that the L-shaped clamping plate clamps the steel plate from the front and back sides of the steel plate. Then, according to the width of the steel plate, the position of the limit slider on the L-shaped clamping plate is slidably adjusted, so that the knob pressing bolt can press on the appropriate position at the top of the steel plate. After the position of the limit slider is adjusted, the knob pressing bolt is screwed to make the bottom end of the knob pressing bolt tightly press on the steel plate, thus completing the fixation of the steel plate. Another steel plate is fixed on another group of L-shaped supporting plates in the same way. After the two steel plates are fixed, the motor is started, so that the motor drives the bidirectional threaded rod to rotate, and the bidirectional threaded rod drives the transmission sleeve plate to slide inward along the guide rod. Thus, the guide rod drives the L-shaped supporting plate to slide inward, and the L-shaped supporting plate drives the two steel plates to move inward, so that the two steel plates are spliced together. When clamping the steel plate, the extension lengths of the telescopic cylinder and the clamping cylinder are the same, so that the steel plate is centered at the position of the L-shaped supporting plate, and the front and rear ends of the two steel plates are aligned. Then welding can be carried out, which can make it easier to align the steel plates. By the steel plate abutting against the L-shaped supporting plate, and together with the clamping and fixation of the L-shaped clamping plate and the knob pressing bolt, the steel plate is fixed more firmly, preventing displacement during the welding process and improving the welding quality of the steel plate splicing welding.

The following embodiments are used to illustrate the present utility model, but are not used to limit the scope of the present utility model.

[0019] Embodiment

[0020] Please refer to Figures 1-4, A large steel plate welding auxiliary device of the present utility model includes a base 1. At the four corners of the bottom end of the base 1, anchor feet 2 are fixedly provided. A motor 3 is fixedly installed at the right end of the base 1. A bidirectional threaded rod 4 is rotatably installed on the base 1, and the right end of the bidirectional threaded rod 4 is fixedly connected to the output end of the motor 3. Two groups of guide rods 5 are symmetrically and fixedly provided on the base 1. At the center of the bottom ends of two groups of L-shaped support plates 6, transmission sleeve plates 7 are fixedly connected. The two groups of transmission sleeve plates 7 are symmetrically screwed and sleeved on the bidirectional threaded rod 4. Two groups of guide holes are provided on each of the two groups of transmission sleeve plates 7. The two groups of transmission sleeve plates 7 are slidably sleeved on the two groups of guide rods 5 through the cooperation of the guide holes. The two groups of L-shaped support plates 6 are symmetrically distributed on both sides of the base 1. At the front and rear ends of the L-shaped support plates 6, two groups of telescopic cylinders 8 are symmetrically and fixedly installed. The output ends of the two groups of front telescopic cylinders 8 and the output ends of the two groups of rear telescopic cylinders 8 are fixedly connected with connecting plates 9. Two groups of clamping cylinders 10 are respectively fixedly installed on the two groups of connecting plates 9. The output ends of the two groups of clamping cylinders 10 are fixedly connected with L-shaped clamping plates 11. The bottom ends of the two groups of L-shaped clamping plates 11 are horizontal with the top end of the L-shaped support plate 6. Limiting guide grooves are provided at the tops of the two groups of L-shaped clamping plates 11. Two groups of limiting sliders 12 are slidably installed on each of the two groups of L-shaped clamping plates 11 through the cooperation of the limiting guide grooves. Knob pressing bolts 13 are screwed on the four groups of limiting sliders 12;During use, according to the length of the steel plate, the telescopic cylinder 8 is started, so that the telescopic cylinder 8 pushes the connecting plate 9 to move outward. The connecting plate 9 drives the clamping cylinder 10 and the L-shaped clamping plate 11 to move outward, so that the steel plate can be placed on the L-shaped supporting plate 6. Then, the steel plate is placed on the L-shaped supporting plate 6. The width of the L-shaped supporting plate 6 is smaller than the width of the steel plate, so that the left end of the steel plate abuts against the left side of the L-shaped supporting plate 6, and the right end of the steel plate extends out of the right end of the L-shaped supporting plate 6. Then, by starting the clamping cylinder 10, the clamping cylinder 10 is pushed to move the L-shaped clamping plate 11 toward the steel plate, so that the L-shaped clamping plate 11 clamps the steel plate from both the front and back sides of the steel plate. Then, according to the width of the steel plate, the position of the limit sliding block 12 on the L-shaped clamping plate 11 is slidably adjusted so that the knob pressing bolt 13 can press on the appropriate position at the top of the steel plate. After the position of the limit sliding block 12 is adjusted, the knob pressing bolt 13 is screwed to make the bottom end of the knob pressing bolt 13 tightly press on the steel plate, thus completing the fixation of the steel plate. Another steel plate is fixed on another group of L-shaped supporting plates 6 in the same way. After the two steel plates are fixed, by starting the motor 3, the motor 3 drives the bidirectional threaded rod 4 to rotate, so that the bidirectional threaded rod 4 drives the transmission sleeve plate 7 to slide inward along the guide rod 5, thereby driving the guide rod 5 to drive the L-shaped supporting plate 6 to slide inward, so that the L-shaped supporting plate 6 drives the two steel plates to move inward, and further the two steel plates are spliced together. When clamping the steel plate, the extension lengths of the telescopic cylinder 8 and the clamping cylinder 10 are the same, so that the steel plate is centered at the position of the L-shaped supporting plate 6, and the front and back ends of the two steel plates are aligned. Then welding can be carried out, which can make it easier to align the steel plates. By the steel plate abutting against the L-shaped supporting plate 6, plus the clamping and fixation of the L-shaped clamping plate 11 and the knob pressing bolt 13, the steel plate is fixed more firmly, preventing displacement during the welding process and improving the welding quality of the steel plate butt welding.

[0021] Four corners at the bottom of each group of the L-shaped supporting plates 6 are fixedly provided with supporting rollers 14, and the bottom of the supporting rollers 14 is supported by the top of the base 1; by providing the supporting rollers 14, the L-shaped supporting plate 6 can be supported. When the L-shaped supporting plate 6 moves, the L-shaped supporting plate 6 drives the supporting rollers 14 to roll on the base 1, thereby preventing the L-shaped supporting plate 6 from bending the bidirectional threaded rod 4 and the guide rod 5 when moving and ensuring the smooth movement of the L-shaped supporting plate 6.

[0022] Two groups of T-shaped guide rods 15 are symmetrically and slidably arranged on each of the four groups of the connecting plates 9, and the outer side of each group of the L-shaped clamping plates 11 is connected to the two groups of T-shaped guide rods 15 on each of the connecting plates 9; by providing the T-shaped guide rods 15, the movement of the L-shaped clamping plate 11 pushed by the clamping cylinder 10 can be made more stable and reliable.

[0023] Fastening rubber pads 16 are fixedly connected to the inner walls on the outer sides of each group of the L-shaped supporting plates 6 and the vertical inner walls of each of the four groups of the L-shaped clamping plates 11; by providing the fastening rubber pads 16, the steel plate can be clamped and fixed more tightly and firmly.

[0024] Sliding sleeves 17 are fixedly arranged in the guiding holes of the two groups of transmission sleeve plates 7; by providing the sliding sleeves 17, the sliding of the transmission sleeve plates 7 on the guiding rods 5 can be made smoother.

[0025] For a large steel plate welding auxiliary device of the present utility model, its working principle is as follows: during use, according to the length of the steel plate, the telescopic cylinder 8 is started, so that the telescopic cylinder 8 pushes the connecting plate 9 to move outward. The connecting plate 9 drives the clamping cylinder 10 and the L-shaped clamping plate 11 to move outward, so that the steel plate can be placed on the L-shaped supporting plate 6. Then the steel plate is placed on the L-shaped supporting plate 6. The width of the L-shaped supporting plate 6 is smaller than the width of the steel plate, so that the left end of the steel plate abuts against the left side of the L-shaped supporting plate 6, and the right end of the steel plate extends out of the right end of the L-shaped supporting plate 6. Then, by starting the clamping cylinder 10, the clamping cylinder 10 is made to push the L-shaped clamping plate 11 to move towards the steel plate, so that the L-shaped clamping plate 11 clamps the steel plate from the front and back sides of the steel plate. Then, according to the width of the steel plate, the position of the limiting slider 12 on the L-shaped clamping plate 11 is slidably adjusted so that the knob pressing bolt 13 can press on the appropriate position at the top of the steel plate. After the position of the limiting slider 12 is adjusted, the knob pressing bolt 13 is screwed to make the bottom end of the knob pressing bolt 13 tightly press on the steel plate to complete the fixation of the steel plate. Another steel plate is fixed on another group of L-shaped supporting plates 6 in the same way. After the two steel plates are fixed, by starting the motor 3, the motor 3 drives the bidirectional threaded rod 4 to rotate, so that the bidirectional threaded rod 4 drives the transmission sleeve plate 7 to slide inwards along the guiding rod 5, thereby making the guiding rod 5 drive the L-shaped supporting plate 6 to slide inwards, making the L-shaped supporting plate 6 drive the two steel plates to move inwards, and further making the two steel plates spliced together. When clamping the steel plate, the extended lengths of the telescopic cylinder 8 and the clamping cylinder 10 are the same, so that the steel plate is centered at the position of the L-shaped supporting plate 6, and the front and back ends of the two steel plates are aligned, and then welding can be carried out.

[0027] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present utility model, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as the protection scope of the present utility model.
