[0025] Reference Figure 1-2 A positioning device for an automotive inner panel drawing die includes a base 1, a positioning assembly 2, a fixing plate 3, a drive assembly 6, a clamping plate 4, and a damping assembly 7. The fixing plate 3 is fixed above the base 1. The drive assembly 6 is mounted on the fixing plate 3. The clamping plate 4 moves vertically under the action of the drive assembly 6. The damping assembly 7 is mounted on the positioning assembly 2. The clamping plate 4 and the damping assembly 7 cooperate to clamp the sheet metal. The drive assembly 6 includes a second motor 601, a worm gear 602, a worm wheel 603, a transmission shaft 604, a first bevel gear 605, a second bevel gear 606, a threaded rod 607, and a threaded sleeve 608. The second motor 601 is mounted on the fixing plate 3. The output end of the second motor 601 is connected to the worm gear 602. The worm wheel 603 is sleeved on the transmission shaft 604. The worm wheel 603 and the worm gear 602 are connected to each other. 02. The two ends of the drive shaft 604 are equipped with bevel gear 1 605, which mesh with each other. The bottom of bevel gear 2 606 is equipped with a rotating shaft, which is rotatably connected to the fixed plate 3. A threaded rod 607 is provided on bevel gear 2 606, and a threaded sleeve 608 is threadedly fitted on the top of the threaded rod 607. The threaded sleeve 608 is connected to the bottom of the clamping plate 4. By setting the drive assembly 6, the drive shaft 604 can drive the bevel gear 1 605 and bevel gear 2 606 to rotate, so that the threaded rod 607 rotates in the threaded sleeve 608. The threaded sleeve 608 drives the clamping plate 4 at the top to move vertically upward. The plate is placed on the clamping plate 4 until it presses against the damping assembly 7 below the limiting plate 205 and deforms it, preventing rigid contact from damaging the surface of the plate.

[0026] A pressure sensor is installed at the bottom of the pressure plate 702. The pressure sensor can accurately reflect the magnitude of the clamping force, so that it can not only firmly fix the inner panel of the car and prevent the inner panel from shifting during the drawing process, but also avoid the inner panel from loosening due to insufficient clamping force, which would affect the drawing effect and dimensional accuracy, ensure the smooth progress of the drawing process, and improve the consistency and pass rate of the products.

[0027] Example 2

[0028] Positioning component 2 includes a motor 201, a bidirectional screw 202, a sliding seat 203, a bracket 204, and a limiting plate 205. A groove 101 is formed on the inner wall of the base 1. Two sets of sliding seats 203 are provided, with both ends of the two sets inserted into the groove 101 and slidingly engaged with it. The motor 201 is located on the outer wall of the base 1, and its output end is connected to the bidirectional screw 202. The two sets of sliding seats 203 are threadedly engaged with the bidirectional screw 202. When the motor 201 rotates, the bidirectional screw 202 rotates accordingly, causing the two sets of sliding seats 203 to move in opposite directions. The bracket 204 is located on the sliding seat 205. On the movable seat 203, the limiting plate 205 is set on the top of the bracket 204.

The spring 701 is set at the bottom of the limiting plate 205, and the pressure plate 702 is fixed to the bottom end of the spring 701. With this design, since the two sets of sliding seats 203 can move freely under the drive of the bidirectional screw 202, the distance between the limiting plates 205 can be flexibly adjusted according to the size of the object to be positioned. This adjustable design allows the positioning component 2 to adapt to objects of different sizes, improving the versatility and applicability of the positioning component 2.
