Description

Technical Field

[0001] The utility model relates to the technical field of supporting facilities for punching machines, and in particular to a positioning mechanism of a punching machine for processing automobile parts. Background Art

[0002] A punch press is a stamping press. In national production, the stamping process has the advantages of saving materials and energy, high efficiency, low technical requirements for operators, and the ability to produce products that cannot be produced by mechanical processing through various mold applications. Therefore, its use is becoming more and more extensive. Stamping production is mainly for sheet metal. Through molds, it can produce blanking, punching, forming, drawing, trimming, fine blanking, shaping, riveting and extrusion, etc., and is widely used in various fields.

[0003] The design principle of the punch press is to convert circular motion into linear motion. The main motor outputs power to drive the flywheel, and the clutch drives the gear, crankshaft (or eccentric gear), connecting rod, etc. to achieve the linear motion of the slider. The movement from the main motor to the connecting rod is circular motion. There must be a transition point between the circular motion and the linear motion between the connecting rod and the slider. There are roughly two mechanisms in its design, one is a ball type and the other is a pin type (cylindrical type). Through this mechanism, the circular motion is converted into the linear motion of the slider. The punch press applies pressure to the material to make it plastically deform and obtain the required shape and precision. Therefore, a set of molds (upper mold and lower mold) must be used to place the material between them. The machine applies pressure to make it deform. The reaction force caused by the force applied to the material during processing is absorbed by the punch press machine body. It is widely used in the stamping and forming of electronics, communications, computers, household appliances, furniture, transportation, (cars, motorcycles, bicycles) hardware parts, etc.

[0004] However, during the operation of the punching machine, the workpiece is usually fixed on the punching table for processing, and ordinary clamping workpieces cannot be positioned. There is a deviation in the corresponding position of the punching hole after clamping. In view of this, a positioning mechanism for a punching machine for processing automotive parts is developed. Utility Model Content

[0005] The utility model provides a positioning mechanism for a punching machine for processing automobile parts, which solves the problem in the prior art that ordinary clamping workpieces cannot be positioned, and there is a deviation in the corresponding position of the punching holes after clamping, which causes errors in the punching position and size.

[0006] The technical solution of the utility model is as follows:

[0007] A punching table, wherein a punching hole is formed on the punching table;

[0008] A bidirectional clamping assembly, wherein the bidirectional clamping assembly is arranged on the stamping table;

[0009] Auxiliary conveying components, the auxiliary conveying components are arranged on two opposite side walls of the punching table;

[0010] The bidirectional clamping assembly includes a clamping plate, which is arranged on the stamping table. A door-shaped connecting frame is arranged on the back of the clamping plate, and the door-shaped connecting frame is connected to a transverse plate, and a driving rack is connected to the transverse plate. A motor frame is arranged on the back of the stamping table, and an output motor is arranged on the motor frame. A driving gear is arranged at the output end of the output motor, and the driving gear is meshed with the driving rack.

[0011] As a further technical solution, a limiting track is provided on the driving rack, an L-shaped connecting frame is provided at the bottom of the punching table, a limiting protrusion is provided on the L-shaped connecting frame, and the limiting protrusion is embedded in the limiting track.

[0012] As a further technical solution, the auxiliary conveying assembly includes an inclined frame, which is arranged on two opposite side walls of the punching table, and a conveyor belt is arranged inside the inclined frame.

[0015] As a further technical solution, punching machine connection mounting columns are provided at the four corners of the bottom surface of the punching table.

[0016] As a further technical solution, the rotation speed and direction of the conveyor belts located on both sides of the punching table are the same.

[0017] As a further technical solution, the conveyor belt adopts PVC belt transmission.

[0018] The working principle and beneficial effects of the utility model are:

A door-type connecting frame 3-2 is arranged on the back of the clamping plate 3-1, and the door-type connecting frame 3-2 is connected to a transverse plate 3-3, and a driving rack 3-4 is connected to the transverse plate 3-3. A motor frame 3-5 is arranged on the back of the stamping table 1, and an output motor 3-6 is arranged on the motor frame 3-5. A driving gear 3-7 is arranged at the output end of the output motor 3-6, and the driving gear 3-7 is meshed with the driving rack 3-4.

[0031] In this embodiment, the motor frame 3-5 is an L-shaped structure, the output motor 3-6 is located on the motor frame 3-5, the main body of the output motor 3-6 is located at the lower end of the driving rack 3-4, and the output end of the output motor 3-6 drives the driving gear 3-7 to rotate. The driving gear 3-7 is meshed with two parallel driving racks 3-4. When the driving gear 3-7 rotates, the driving rack 3-4 moves accordingly, thereby driving the clamping plate 3-1 to clamp.

[0032] Specifically, a limiting track 3-8 is provided on the driving rack 3-4, an L-shaped connecting frame 3-9 is provided at the bottom of the punching table 1, a limiting protrusion 3-10 is provided on the L-shaped connecting frame 3-9, and the limiting protrusion 3-10 is embedded in the limiting track 3-8.

[0033] In this embodiment, the limiting track 3-8 and the limiting protrusion 3-10 are used to limit the driving rack 3-4 to prevent the driving rack 3-4 from moving around.

[0034] Furthermore, the auxiliary conveying assembly 4 includes an inclined frame 4 - 1 , which is disposed on two opposite side walls of the punching table 1 , and a conveyor belt 4 - 2 is disposed inside the inclined frame 4 - 1 .

[0036] Furthermore, an anti-slip pad 5 is provided on the inner side of the clamping plate 3 - 1 . The clamping plate 3 - 1 is a rectangular structure.
