The plates that make up the electric vehicle frame usually have holes. It is a common technical means to weld and position the plates with holes. Based on this, a welding positioning device for plates with holes is proposed. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a positioning device for a perforated plate, which is convenient for positioning the perforated plate body.

BRIEF DESCRIPTION OF THE DRAWINGS

[0014] Attached Figure 2 It is a structural schematic diagram of the positioning block and the positioning table. DETAILED DESCRIPTION

[0015] The utility model is further described below in conjunction with the accompanying drawings.

[0016] As attached Figures 1 to 2 The positioning device of a perforated plate comprises a perforated plate 1 and a positioning platform 2. The perforated plate 1 is placed on the positioning platform 2, and the lower plate surface of the perforated plate 1 is in contact with the upper contour surface of the positioning platform 2. The positioning platform 2 provides support for the perforated plate 1. At least one positioning hole 3 is provided on the perforated plate 1, and the perforated plate 1 is positioned through the positioning hole 3.

[0017] A positioning block 4 is provided on the positioning platform 2, and a pressure edge portion 5 is provided on the positioning block 4. The lower end of the positioning block 4 is a clamping portion 6. A downward pressing mechanism is also provided on the positioning platform 2. When the positioning block 4 is opposite to the positioning hole 3, the positioning block 4 can be driven downward by the downward pressing mechanism. As the positioning block 4 moves downward, the clamping portion 6 can be inserted into the positioning hole 3. At this time, the pressure edge portion 5 is correspondingly pressed on the perforated plate 1. The pressure edge portion 5 and the positioning platform 2 cooperate to clamp the upper and lower plate surfaces of the perforated plate 1 to limit the displacement of the perforated plate 1 in the vertical direction. The shape of the clamping portion 6 is adapted to the shape of the positioning hole 3. When the clamping portion 6 is inserted into the positioning hole 3, the displacement of the perforated plate 1 in the horizontal direction can be limited, thereby realizing the positioning of the perforated plate 1.

[0018] As attached Figure 2 As shown in , the bottom end of the block portion 6 has a slit 7, and the positioning platform 2 is provided with an extrusion block 8, and the slit 7 is vertically opposite to the extrusion block 8. When the positioning pressing block 4 is driven downward by the pressing mechanism and the block portion 6 is gradually inserted into the positioning hole 3, the extrusion block 8 will be correspondingly squeezed into the slit 7, thereby stretching the block portion 6, and the block portion 6 will be clamped in the positioning hole 3 after being stretched, so that the block portion 6 and the positioning hole 3 are closely fitted, so as to improve the positioning accuracy of the perforated plate 1.

[0019] The slit 7 is a strip-shaped slit, and the clamping block is divided into two parts, left and right, with the slit 7 as the boundary, and the slit 7 gradually narrows along the depth direction. The extrusion block 8 is a long strip, and the extrusion block 8 gradually narrows from the bottom to the top. The vertical cross-section of the extrusion block 8 is conical, and the taper of the extrusion block 8 is slightly larger than the taper of the slit 7. When the extrusion block 8 is squeezed into the slit 7, the two parts of the clamping block with the slit 7 as the boundary are stretched open, so that the clamping block can be clamped in the positioning hole 3.

[0020] The positioning hole 3 on the perforated plate 1 is a through hole. When the edge pressing part 5 is pressed on the perforated plate 1, a gap is left between the bottom end of the block part 6 and the table surface of the positioning table 2 to ensure that the edge pressing part 5 can be attached to the upper plate surface of the perforated plate 1 for positioning.

[0021] The positioning platform 2 is provided with a guide rod 9, which is a vertical rod. The positioning block 4 is provided with a guide hole, which is matched with the guide rod 9 for vertical sliding, so that the positioning block 4 can slide vertically along the guide rod 9. When the pressing mechanism presses down the positioning block 4, the positioning block 4 will move down along the guide rod 9.

[0022] The guide rod 9 has a threaded section. Figure 2 As shown in the figure, the threaded section is located at the upper end of the guide rod 9. The pressing mechanism includes a nut 10, which is threadedly matched with the threaded section of the guide rod 9. When the nut 10 is rotated downward on the threaded section, the nut 10 presses down the positioning block 4 accordingly, thereby driving the positioning block 4 to slide downward along the guide rod 9.

[0023] The guide hole is a circular hole, and the guide hole is rotatably matched with the guide rod 9, so that the positioning block 4 can rotate on the positioning platform 2. The slit 7 is limitedly matched with the extrusion block 8. When the extrusion block 8 is squeezed into the slit 7, the extrusion block 8 can limit the rotation of the clamping block 6, thereby limiting the rotation of the positioning block 4 relative to the guide rod 9, thereby limiting the rotation of the perforated plate 1 between the edge pressing portion 5 and the positioning platform 2.

[0024] As attached Figure 1 In one embodiment shown in the figure, the part to be welded is a bucket seat bracket on an electric vehicle frame, and the bucket seat bracket is welded by three plates, one of which is a perforated plate 1 with a rectangular positioning hole 3, and a positioning block 4 is provided on the positioning platform 2. The clamping block portion 6 at the lower end of the positioning block 4 is correspondingly clamped in the positioning hole 3, and the edge pressing portions 5 on both sides of the positioning block 4 are correspondingly pressed on the perforated plate 1, thereby realizing the positioning of the perforated plate 1 and facilitating subsequent welding processing.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
