[0023] Embodiment 1

[0024] A high-precision sheet metal part batch forming device includes a base 1, a mold 2 and a clamping mechanism 3. The base 1 is assembled with a welding machine group, and the mold 2 is spliced with the base 1 for adjusting the position of the mold 2. The clamping mechanism 3 is used to adjust the edge positions of two clamped sheet metal parts.

[0025] A number of pin holes are provided on the base 1, and pins are provided on the mold 2. By inserting the pins into different pin holes, the purpose of fixing the mold 2 at different positions on the base 1 is achieved.

[0026] The mold 2 includes a template 21 and a mold core 22. Pins are fixed on the template 21, and the mold core 22 is detachably connected to the template 21. The mold core 22 is a quarter-spherical mold. When in use, the quarter-spherical sheet metal part is attached to the mold core 22.

[0027] The clamping mechanism 3 includes sliding grooves 31, clamping plates 32, double-headed studs 33 and handles 34. Sliding grooves 31 are provided on both sides of the mold core 22, and clamping plates 32 are slidably connected in the sliding grooves 31. The cross-section of the clamping plate 32 is U-shaped, and both sides of the sheet metal part can be inserted into the corresponding clamping plates 32. By adjusting the positions of the clamping plates 32, the rapid fixation of the sheet metal position is achieved.

[0028] Furthermore, the two clamping plates 32 are in threaded transmission connection with the same double-headed stud 33, and a handle 34 is rotatably connected to the double-headed stud 33. The position of the handle 34 can be fixed at the end of the double-headed stud 33 or in the middle of the double-headed stud 33.

[0029] For the welding of the two quarter-spherical sheet metal parts targeted by this solution, it is necessary to synchronously align the sheet metal parts clamped by the two clamping mechanisms 3. Specifically, either fix the two handles 34 to the ends of the stud 33 simultaneously, or fix the two handles 34 to the middle of the stud 33 simultaneously. By using a belt drive connection or a gear drive connection between the two handles 34, the two studs 33 rotate at the same speed, driving the two clamping plates 32 to move inward or outward simultaneously. The specific rotation direction of the stud 33 is not considered because it can be specifically selected according to the drive connection method between the handles 34 during actual operation.

[0030] The above-mentioned stud 33 refers to a cylinder with threads of opposite rotation directions at both ends. When rotating, it can drive the components located at both ends to approach or move away from each other.

[0031] The above technical solution is also applicable to the welding after butt-joint of curved sheet metal parts.

[0032] Embodiment 2

[0033] On the basis of Embodiment 1, a pressing plate mechanism 4 is further provided. The pressing plate mechanism 4 includes a V-shaped clip 41, a cylinder 42, a cam 43, and a tension cord 44. A relief groove is provided on the template 21, and the V-shaped clip 41 slides in the relief groove. The two symmetrical V-shaped clips 41 are connected by the tension cord 44. A cylinder 42 is installed below the template 21. The cylinder block of the cylinder 42 is fixed to the template 21, and the telescopic rod of the cylinder 42 is fixedly connected to the cam 43. The cam 43 abuts against the tension cord 44. When the cam 43 presses the tension cord 44, the two V-shaped clips 41 approach each other under the pulling of the tension cord 44 to clamp the sheet metal part located between the V-shaped clip 41 and the die core 22. When the cam 43 does not press the tension cord 44, the user can take out or put in the sheet metal part, achieving the purpose of quickly replacing the sheet metal part and improving the overall efficiency during the processing of a batch of sheet metal parts.

[0034] The working principle of the present utility model:

[0035] This application mainly uses a belt drive method or a gear drive method to drive the two studs 33 to drive the clamping plates 32 to contract inward or expand outward synchronously, so as to determine the accuracy of the relative positions of the sheet metal parts on the two die cores 22, facilitating the user to weld the positioned sheet metal parts and improving the precision during batch processing of sheet metal parts.
