Utility Model Content

[0004] The main purpose of this utility model is to provide a quick clamping fixture for 3D laser cutting of automotive heat shields, which can effectively solve the problem that the pressing mechanism of the positioning fixture used in the background technology is fixed in position and not easy to be adjusted by the operator. The fixed pressing mechanism can only clamp workpieces of specific specifications. If the product is changed, the fixture cannot be adjusted, resulting in incompatibility with the new workpiece.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A quick-clamping fixture for 3D laser cutting of automotive heat shields includes a base. Several first electric push rods are fixedly mounted on the upper surface of the base. Each first electric push rod has a mounting bracket fixedly mounted at its output end. A first motor is fixedly mounted at the bottom of each mounting bracket. The output shaft of each first motor passes through the corresponding mounting bracket and is fixedly mounted with a circular plate. A positioning bracket is fixedly mounted on the upper surface of each circular plate. A support bracket is movably arranged inside the positioning bracket. A pressure head is fixedly mounted at one end of the support bracket.

[0007] Preferably, a lead screw is rotatably mounted on one side of the inner wall of each positioning frame, and each support frame is threaded onto one side of the corresponding lead screw.

[0008] A second motor is fixedly installed on one side of each positioning frame, and one end of each lead screw passes through the corresponding positioning frame and is fixedly connected to the output shaft end of the opposite second motor.

[0009] Preferably, two positioning rods are fixedly installed on one side of the inner wall of each positioning frame, and each support frame is slidably disposed on one side of the corresponding positioning rod.

[0010] Preferably, a connecting ring is fixedly installed on the upper surface of each mounting bracket, and each circular plate is rotatably installed inside the corresponding connecting ring via a bearing.

[0011] Preferably, each pressure head has a stepped hole on its upper surface, and a number of top plates are slidably disposed through the inner wall of each stepped hole, and a trapezoidal plate is fixedly installed on the upper surface of each top plate.

[0012] Each of the stepped holes has several spring rods on its inner wall, and the movable end of each spring rod is fixedly connected to the corresponding trapezoidal plate.

[0013] Preferably, a second electric actuator is fixedly installed at the upper end of the pressure head, and a push ball is fixedly installed at the output end of each second electric actuator.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

Detailed Implementation

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0025] like Figures 1-7 As shown, a quick-clamping fixture for 3D laser cutting of automotive heat shields includes a base 1. Several first electric push rods 2 are fixedly installed on the upper surface of the base 1. Each first electric push rod 2 has a mounting bracket 3 fixedly installed at its output end. Each mounting bracket 3 has a first motor 301 fixedly installed at its bottom. The output shaft end of each first motor 301 passes through the corresponding mounting bracket 3 and is fixedly installed with a circular plate 302. Each circular plate 302 has a positioning bracket 4 fixedly installed on its upper surface. A support bracket 5 is movably arranged inside the positioning bracket 4. A pressure head 6 is fixedly installed at one end of the support bracket 5.

[0026] Each positioning frame 4 has a lead screw 7 rotatably installed on one side of its inner wall, and each support frame 5 is threaded onto one side of the corresponding lead screw 7.

[0027] A second motor 8 is fixedly installed on one side of each positioning frame 4, and one end of each lead screw 7 passes through the corresponding positioning frame 4 and is fixedly connected to the output shaft end of the opposite second motor 8.

[0028] Two positioning rods 9 are fixedly installed on one side of the inner wall of each positioning frame 4, and each support frame 5 is slidably set on one side of the corresponding positioning rod 9.

[0029] The worker places the car heat shield on the surface of the base 1, and then starts the first motor 301, which drives the circular plate 302 to rotate. The circular plate 302 then drives the pressure head 6 to rotate. The worker starts the second motor 8, which drives the lead screw 7 to rotate. The rotating lead screw 7 drives the support frame 5 to move along the positioning rod 9 by screwing in the thread. This allows the support frame 5 to drive the pressure head 6 to move along the positioning frame 4. The worker can then adjust the horizontal position of the pressure head 6 according to the specifications of the heat shield to accommodate new workpieces.

[0030] In another embodiment of this utility model, a connecting ring 10 is fixedly installed on the upper surface of each mounting bracket 3, and each circular plate 302 is rotatably installed inside the corresponding connecting ring 10 through a bearing 11.

[0031] By setting the connecting ring 10 and the bearing 11, the connecting ring 10 serves as a transition component between the mounting bracket 3 and the circular plate 302, providing a stable mechanical connection and ensuring that the circular plate 302 maintains concentricity during rotation, thus avoiding wobbling.

[0032] In another embodiment of the present invention, a stepped hole 601 is provided on the upper surface of each pressure head 6, and a plurality of top plates 12 are slidably disposed through the inner wall of each stepped hole 601, and a trapezoidal plate 13 is fixedly installed on the upper surface of each top plate 12.

[0033] Each stepped hole 601 has several spring rods 14 on its inner wall, and the movable end of each spring rod 14 is fixedly connected to the corresponding trapezoidal plate 13.

[0034] A second electric actuator 15 is fixedly installed on the upper end of the pressure head 6, and a push ball 16 is fixedly installed on the output end of each second electric actuator 15.

[0035] The operator activates the second electric actuator 15, which pushes the ball 16 to push the trapezoidal plate 13, allowing the top plate 12 to move. When the pressure head 6 is fixing the surface of the large hole, after the pressure head 6 enters the hole, the top plate 12 moves and presses against the inner wall of the hole, thus completing the fixing. After the pressing work is completed, the operator controls the output end of the second electric actuator 15 to retract, causing the ball 16 to reset. Under the pushing action of the spring rod 14, the top plate 12 resets.

[0036] The working principle of this rapid clamping fixture for 3D laser cutting of automotive heat shields:

[0037] In use, the operator places the car heat shield on the surface of the base 1, then starts the first motor 301, causing its output shaft to drive the circular plate 302 to rotate, which in turn drives the pressure head 6 to rotate. The operator then starts the second motor 8, causing its output shaft to drive the lead screw 7 to rotate. The rotating lead screw 7 drives the support frame 5 to move along the positioning rod 9 by screwing in, so that the support frame 5 can drive the pressure head 6 to move along the positioning frame 4. This allows the operator to adjust the horizontal position of the pressure head 6 according to the specifications of the heat shield to accommodate new workpieces.

[0038] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. For those skilled in the art, other variations or modifications can be made based on the above description. It is impossible to exhaustively list all the implementation methods here. Any obvious variations or modifications derived from the technical solutions of this utility model are still within the protection scope of this utility model.
