The terms used in the specification of the utility model herein are only for the purpose of describing specific embodiments and are not intended to limit the utility model.

[0028] Reference is made to Figures 1-4The utility model discloses an automatic welding positioning tool, including positioning table 10 and two sets of positioning components, two sets of positioning components are spaced apart in first direction, and two sets of positioning components can move close to each other or move away from each other along the first direction.

[0029] Two positioning blocks 23 and positioning block driving part 24 are installed on positioning seat 21, and two positioning blocks 23 can move close to each other or move away from each other along the second direction, and positioning block driving part 24 can drive positioning block 23 to move along the second direction, so that two positioning blocks 23 can move close to each other or move away from each other on positioning seat 21. In addition, positioning block 23 includes first positioning side and second positioning side 232, and first positioning side and second positioning side 232 are connected by circular arc segment 233; first positioning side is provided with positioning circular arc plate 231.

[0030] It should be noted that the first direction in the embodiment refers to the length direction of the positioning table 10, and the second direction refers to the width direction of the positioning table 10.

[0031] On the basis of the above structure, when the automatic welding positioning tool of the utility model is used, referring to Figure 4 According to the length size of the workpiece 30, one of the positioning seats 21 is driven by the positioning seat driving part 22 to move towards the other positioning seat 21, so that the spacing between the two positioning seats 21 can be adjusted under the driving of the positioning seat driving part 22, and after adjusting the spacing between the two positioning seats 21, the positioning spacing formed between the positioning circular arc plates 231 of the positioning blocks 23 on the two positioning seats 21 can be adjusted to be consistent with the length of the workpiece 30.

[0032] At the same time, the two positioning blocks 23 on the same set of positioning seats 21 can move close to each other or move away from each other under the action of the positioning block driving part 24, so that the positioning spacing between the second positioning sides 232 on the two positioning blocks 23 can be adjusted to be consistent with the width direction of the workpiece 30.

[0033] When the workpiece 30 is placed, the workpiece 30 can be inverted and buckled to the two positioning seats 21, and the positioning arc plates 231 of the two positioning blocks 23 of each set of positioning seats 21 can respectively match the arc connection positions of the bent edges of the ends of the workpiece 30, and the second positioning side edges 232 of the two positioning blocks 23 can respectively abut against the width direction two side edges of the same end of the workpiece 30, so that the abutment is realized. The inner side of the bent edge of the workpiece 30 in the length direction is matched and positioned by the arc of the arc positioning plate 28. This is adapted to the arc structure of the workpiece 30, and the structure is more stable after positioning.

[0034] In addition, the first positioning side edge and the second positioning side edge 232 are also connected by the arc segment 233, so that after the long side and the wide side of the workpiece 30 are respectively positioned, the arc segment 233 is matched and abutted at the connection position of the two sides in an arc, so as to prevent the connection position from being a right angle and scratching the workpiece 30.

[0035] Of course, the spacing between the positioning seats 21 in the present application is driven by the positioning seat driving member 22 to realize the adjustment of the positioning spacing in the length direction, and the spacing between the two positioning blocks 23 in the same set is adjusted by the positioning block driving member 24 to realize the adjustment of the positioning spacing in the width direction, so as to adapt to the positioning of different workpieces 30.

[0036] Further, the positioning assembly further comprises two positioning side plates 25 and a positioning side plate driving member 26, and the two positioning side plates 25 are arranged on the two sides of the positioning seat 21 in the second direction, so that the positioning side plate driving member 26 can drive the positioning side plate 25 to slide in the second direction.

[0037] When positioning, the turned-up edge of the workpiece 30 in the width direction can extend into the space between the positioning side plate 25 and the second positioning side edge 232, and then the positioning side plate 25 is driven by the positioning side plate driving member 26 to move close to the second positioning side edge 232, so that the turned-up edge of the workpiece 30 can be clamped between the positioning side plate 25 and the second positioning side edge 232, preventing shaking.

[0038] Further, the positioning seat 21 is further provided with a positioning strip 27, the positioning strip 27 extends in the second direction, and the positioning strip 27 is located between the two positioning side plates 25; and the positioning strip 27 and the positioning arc plate 231 are spaced apart to form a positioning interval. On the basis of this structure, when the workpiece 30 is positioned, the turned-up edges on the two sides of the workpiece 30 in the width direction can be positioned by the two positioning side plates 25, the bent edge of the workpiece 30 in the length direction can be positioned and guided into the positioning interval by the positioning arc plate 231, and the outer side can be limited by the positioning strip 27, so that the turned-up edges on the two sides of the workpiece 30 and the bent edges at the two ends are all limited by the positioning structure, so that the positioning structure is more stable.

[0039] Specifically, the positioning table 10 is provided with two first sliding rails 11 extending in a first direction, and the two first sliding rails 11 are spaced apart in a second direction; the positioning seat 21 is provided with first sliding blocks 211 on both sides; and the first sliding blocks 211 are in sliding cooperation with the first sliding rails 11. In this way, when the positioning seat driving member 22 drives the positioning seat 21 to move in the first direction, the positioning seat 21 can realize stable sliding by the sliding cooperation between the first sliding blocks 211 and the first sliding rails 11.

[0040] Further, the positioning seat 21 is provided with a second sliding rail extending in a second direction, and the bottom end of the positioning block 23 is provided with a second sliding block; the second sliding block is in sliding cooperation with the second sliding rail. Similarly, when the positioning block driving member 24 drives the positioning block 23 to slide in the second direction, the positioning block 23 can realize stable sliding by the sliding cooperation between the second sliding block and the second sliding rail.

[0041] Further, the positioning seat 21 is provided with positioning plates 28 on both sides, and the positioning plates 28 are provided with first positioning holes 281; and the positioning table 10 is provided with a plurality of second positioning holes 12 spaced apart in the first direction; the first positioning hole 281 can correspond to one of the second positioning holes 12 when the positioning seat 21 slides, and a positioning column is inserted.

[0042] On the basis of the structure, since the positioning seat 21 and the positioning table 10 are in sliding connection, if the positioning seat 21 is not positioned when it slides to the corresponding position, the positioning seat 21 is easy to slide due to external force during the machining of the workpiece 30, which affects the machining precision of the workpiece 30.

[0043] Therefore, in the present application, after the positioning seat 21 slides to the position, the positioning plate 28 on the side of the positioning seat 21 is in correspondence with the second positioning hole 12 on the positioning table 10 through the first positioning hole 281 of the positioning plate 28; at this position, the positioning column is inserted into the second positioning hole 12 through the first positioning hole 281, so that the relative sliding between the positioning seat 21 and the positioning table 10 can be limited to prevent sliding during positioning machining.

[0044] When it is necessary to adjust the position of the positioning seat 21 again, the positioning column can be disassembled through the first positioning hole 281 and the second positioning hole 12, so that the positioning seat 21 can slide relative to the positioning table 10 again.

[0045] More specifically, the positioning column in the embodiment includes a positioning screw 29 and a handle, the positioning screw 29 is threaded through the first positioning hole 281 and screwed to the second positioning hole 12; the handle is arranged at the end of the positioning screw 29. When positioning, the handle structure at the end of the positioning screw 29 is held by hand, the positioning screw 29 is rotated, the positioning screw 29 is threaded through the first positioning hole 281 and screwed to the second positioning hole 12 in turn, so that the positioning plate 28 of the positioning seat 21 keeps a relatively fixed state with the positioning table 10, at this time the positioning seat 21 can keep a stable positioning working state. When the position of the positioning seat 21 needs to be adjusted, the handle is usually rotated in the opposite direction, so that the positioning screw 29 is separated from the second positioning hole 12, so that the positioning seat 21 can slide relative to the positioning table 10 again to adjust the positioning interval.

[0046] Of course, the positioning column can also be realized by using the existing pin structure.

[0047] Further, the end surface of the positioning block 23 is provided with a plurality of vacuum suction holes 234, which can be connected with air pipes inside the positioning block 23, one end of the air pipe is communicated with the vacuum suction hole 234, and the other end of the air pipe can be communicated with a vacuum pumping device. In this way, after the workpiece 30 is positioned, the vacuum pumping device can be used for vacuum pumping, and the workpiece 30 can be adsorbed by the negative pressure generated by the vacuum pumping to keep a stable positioning state by the positioning block 23.

[0048] In the case where the vacuum suction hole 234 is not provided, the workpiece 30 is positioned and limited by two groups of positioning blocks 23 at both ends, and the same group of positioning blocks 23 at both sides, which can also keep a stable positioning state.

[0049] Further, the positioning seat driving member 22 includes a first air cylinder, and the same positioning block driving member 24 includes a second air cylinder, so that the corresponding positioning seat 21 and positioning block 23 are driven to move by the air cylinder, so that the positioning interval in the first direction and the second direction can be adjusted, and the driving structure is simple.

[0050] It should be noted that in the embodiment, the positioning seat driving member can be arranged in one of the positioning assemblies to drive one of the positioning seats to slide, or the positioning seat driving member can be arranged in both of the positioning assemblies to drive both of the positioning seats to slide or to slide separately, so that the adjustment range is more flexible.

[0051] The positioning seat of the same group of positioning assemblies can also be provided with only one positioning block driving member to drive one positioning block to adjust the relative position between the two positioning blocks.

[0052] The technical means disclosed by the utility model scheme are not limited to the technical means disclosed by the above-mentioned embodiments, and also include technical schemes composed of any combination of the above technical features. It should be noted that, for ordinary skilled persons in the art, without departing from the principles of the utility model, a number of improvements and refinements can be made, and these improvements and refinements are also considered within the protection scope of the utility model.
