Description

Technical Field

[0001] The present invention relates to the field of manufacturing equipment for motor cowls, and particularly to an automated device for assisting in punching small motor cowls. Background Art

[0002] In the current production of the motor industry, automation and intelligence are manifested in all major process flows. However, in the production of auxiliary parts, some parts have not yet achieved automated production. For example, small motor cowls. The common arrangement methods of the ventilation holes on the cowl are arranged in a way of equal division and radiation according to the pitch circle and arranged in a horizontal and vertical uniform distribution. The processing of the ventilation holes of medium and large motor cowls is generally carried out by controlling the movement of the X and Y axes through a numerical control program, changing the workpiece coordinates according to the drawing requirements, and producing in a single-hole cycle punching manner. When punching the ventilation holes of a small motor cowl, according to the actual arrangement of the ventilation holes, it is punched in 4 - 6 times. Taking the horizontal and vertical uniform distribution of the ventilation holes of the motor cowl as an example (such as Figure 1 ), its technological process is as follows: First, punch out the central circular hole and 4 equally divided ventilation holes on the pitch circle with this hole as the center on a punching press (these 4 holes are used as the orientation reference for the next process), and then transfer to the next process; then, position with the central circular hole and orient with any one ventilation hole on the pitch circle to complete one punching. Next, similarly position with the central circular hole and then rotate 90º, and orient with the ventilation hole adjacent to the ventilation hole used for orientation in the previous process, and continue punching; repeat the above actions for the third and fourth times, and rotate in the same direction during rotation to reduce the cumulative error.

[0003] Defects of the prior art are:

[0004] (1) Larger error. According to the current technological characteristics, although the method of rotating in the same side can reduce the error, due to the two positions of the positioning hole and the orientation hole being adjacent, the error will be amplified as the ventilation hole is farther away from the center of the workpiece.

[0005] (2) More punching processes. Five processes require five punching presses, and the production occupies a large area; if punching is carried out on the same punching press, five sets of molds are required, and changing five sets of molds for punching will increase the production cycle and reduce the production efficiency.

[0006] (3) Poor working environment. When multiple punching presses are in production, the noise generated during the production process is relatively large; in this environment for a long time, the operator is prone to occupational diseases, and it is very difficult to eliminate potential safety hazards.

[0007] (4) Inconvenient to change varieties. There are many specifications of motor cowls. When changing varieties, not only the mold part needs to be replaced, but also the supporting mechanical components need to be replaced, which is time-consuming and laborious.

[0008] Therefore, it is necessary to change the production process to complete multiple processes simultaneously on one punching press, and it is necessary to provide an automated device with high production efficiency and convenient variety change. Summary of the Invention

[0056] In this preferred embodiment, a number of customized double-screw stepper motors work simultaneously, and a number of clamping arms A644 and clamping arms B648 move in opposite directions simultaneously to the dimensions corresponding to the product model.

[0057] The working background of the present invention is a punching machine. The original process of punching five times is changed to arranging three sets of molds side by side in a die set, with the same center distance between the molds. The five-time punching is changed to three-time punching. A preparation station and a transition station are respectively installed on the left and right sides of the die set. The center distance between the preparation station and the molds and between the molds and the transition station is equal to the center distance between the molds, and they are at the same height and on the same straight line to cooperate with the automation device of the present invention.

[0058] The operation process of the present invention is as follows:

[0059] 1. Start the punching machine, turn the punching machine selection switch to the single-action option, and make the punching machine slider in the top dead center state to facilitate the automation device of the present invention to control the punching machine.

[0060] 2. Turn on the power, check the external indication signal on the touch screen, confirm that the punching machine top dead center signal lamp is in the lit state, and confirm the product model in the touch screen dialog box (the automation device of the present invention has built-in relevant parameters for various product models).

[0061] 3. Press the origin button on the operation table to return the X, Y, Z axes and the clamping device to the origin of the automation device of the present invention, that is, the X axis is on the left side, the Y axis is on the rear side, the Z axis is in the lower position, and the clamping device is in the open state.

[0062] 4. After completing the preparation work, the photoelectric sensor on the preparation station located on the left side of the mold senses the incoming material (the indicator light is lit), there is no material on any of the three sets of molds, and the photoelectric sensor on the transition station located on the right side of the mold also shows no material (the indicator light is off), then the start condition of the present invention is met.

[0063] 5. Press the start button, the Y axis moves forward to the set distance (this value can be adjusted through the touch screen), and the four customized twin-screw stepper motors work at the same time. The clamping arm A644 and the clamping arm B648 move to a fixed size that meets the product model (this value can be adjusted through the touch screen to change the clamping force). After the clamping action is completed, the Z axis moves upward until the product is completely separated from the lower die (this value can be adjusted through the touch screen), and the X axis moves to the right by a fixed distance (this value is the center distance between the two molds), and the Z axis moves downward to the origin. The workpiece is in place, and the four customized twin-screw stepper motors work at the same time. The clamping arm A644 and the clamping arm B648 are released and returned to their original positions at the same time. The PLC sends a signal, and the punch slider moves one cycle and returns to the top dead center to standby. While the punch is working, the Y axis returns to its initial position, and then the X axis also returns to its initial position on the left, that is, the device returns to its initial state, thus completing a working cycle. As the left preparation station continues to receive materials, the automation device and the punching machine continue to work according to the above working sequence. After three cycles, the punched motor hood is moved to the right transition station by the present invention and taken away by the robot that performs the next process. After that, a finished product will be removed from the mold every time the punching machine and the automation device work in a cycle.

[0064] When the product model needs to be adjusted, only the positioning parts of the mold part, the preparation station and the transition station need to be replaced. The automation device of the present invention has built-in relevant parameters of various product models. Select the corresponding product model in the touch screen dialog box, press the origin button, and the four customized twin-screw stepper motors work at the same time. The clamping arm A644 and the clamping arm B647 are moved to a fixed size that meets the product model. This value can also be adjusted through the touch screen to change the clamping force.

[0065] The above embodiments of the present invention are merely examples to clearly illustrate the present invention, but are not intended to limit the protection scope of the present invention. All equivalent technical solutions also belong to the scope of the present invention. The patent protection scope of the present invention should be defined by the claims.
