Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, specifically to a device for pressing holes in automotive parts. Background Technology

[0002] Press-punch drilling refers to the process of punching holes in parts using a punch head. Compared to drilling, press-punch drilling has the advantages of faster processing speed and easier waste disposal. Most automotive parts are processed using press-punch drilling when creating holes.

[0003] According to the description in the patent application CN208450343 U published on the State Intellectual Property Office website, "This utility model discloses a device for pressing holes in automotive parts, comprising a pressing device body, a handle ring fixedly installed on the upper outer surface of the pressing device body, a base fixedly installed on the lower outer surface of the pressing device body, a bracket fixedly installed on the upper outer surface of the base, a motor mechanism fixedly installed on the upper end of the bracket, a protective shell fixedly installed on the lower outer surface of the motor mechanism, a pressing column fixedly installed on the lower outer surface of the protective shell, an operating platform fixedly installed on the lower end of the pressing column, and a first inner base fixedly installed on one side of the inner surface of the base. This utility model's device for pressing holes in automotive parts, with a first inner base, a second inner base, a fan, and a protective cover, provides better stability during use, assists in cleaning waste particles generated by the device, and reduces noise and dust, leading to better application prospects."

[0004] Regarding the above description, the applicant believes the following issues exist:

[0005] During use, this design uses a pressure post to press and drill holes in automotive parts. However, this structure cannot effectively secure the parts during the pressing process, causing the pressure post to easily shift and resulting in inaccurate machining accuracy. Furthermore, the automotive parts need to be manually held during the pressing process, posing a safety hazard. Additionally, a motor-driven fan is used to blow waste materials into the collection box, but when the waste materials are heavy, the airflow is insufficient to blow them into the collection box.

[0006] Therefore, it is necessary to design a puncture device for automotive parts that is both practical and has high processing precision. Summary of the Invention

[0019] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0020] 1. This invention, by providing a downward pressing mechanism, uses a hydraulic rod to drive the punch downward during use, causing the punch to press a hole in the automotive part body. During the pressing process, a sliding sleeve presses against the top of the automotive part body, fixing the automotive part body in position. Then, the punch presses down again, causing the punch to press a hole in the automotive part body, thereby preventing the position of the automotive part body from shifting during the pressing process, and thus improving the processing accuracy of the automotive part body.

[0021] 2. The present invention, by providing a sliding shaft, a clamping block, a stop block and a return spring, allows the clamping block to be engaged in the groove of the punch by the pressure of the return spring during use, thereby fixing the punch inside the fixed cylinder. By pulling the stop block outward, the punch can be automatically dislodged, thus facilitating the replacement of punches of different sizes.

[0022] 3. In this invention, by setting up a part fixing mechanism, during use, the connecting table is moved downward by the electric push rod, so that the pressing rotating plate is pressed against the top of the car part body, thus fixing the car part body. Therefore, during the pressing process, there is no need for manual handling of the car part body, avoiding the occurrence of safety hazards. At the same time, the first motor drives the rotating shaft to rotate, so that the rotating shaft drives the rotating table to rotate and change position, thereby rotating and changing the position of the car part body, which facilitates pressing processing at different positions of the car part body.

[0023] 4. In this invention, by setting up a waste cleaning mechanism, the waste generated during the pressing process is automatically slid onto the transmission belt through the unloading track. The second motor drives the active roller to rotate, so that the active roller drives the transmission belt to drive outside the driven roller and the active roller, thereby automatically discharging and collecting the waste generated during the pressing process.

Example 2:

[0041] Please see Figure 5 and Figure 6 Furthermore, in conjunction with Embodiment 1, the part fixing mechanism 6 includes a first motor 61, which is fixedly installed on the top of the base plate 1. A rotating shaft 62 is fixedly installed at the output end of the first motor 61. A rotating table 63 is fixedly installed at the end of the rotating shaft 62 away from the first motor 61. The rotating table 63 is rotatably installed on the top of the processing table 3. An electric push rod 64 is fixedly installed inside the rotating table 63. A connecting platform 65 is fixedly installed on the top of the electric push rod 64. A fixing plate 66 is fixedly installed on the top of the connecting platform 65. A pressing rotating plate 67 is rotatably installed at the bottom of the connecting platform 65. A tension spring 68 is fixedly installed between the pressing rotating plate 67 and the fixing plate 66 to facilitate the fixing of the automobile part body 8.

[0042] Furthermore, a through hole is provided at the corresponding position of the processing table 3 and the rotating shaft 62, and the rotating shaft 62 is rotatably installed inside the through hole. The automotive part body 8 is located between the pressure plate 67 and the rotating table 63, so that the rotating shaft 62 can pass through the processing table 3 to rotate.

[0043] Furthermore, four of each of the fixed plate 66, the pressing rotating plate 67, and the pulling spring 68 are provided. The connecting platform 65 and the corresponding position of the pulling spring 68 are provided with grooves, and the pulling spring 68 passes through the grooves, so that the pulling spring 68 can drive the pressing rotating plate 67 to automatically reset. Example 3:

[0044] Please see Figure 7 and Figure 8 Furthermore, in conjunction with Embodiment 1 and Embodiment 2, the waste cleaning mechanism 7 includes a discharge track 71, which is fixedly installed at the bottom of the processing table 3. A mounting frame 72 is fixedly installed on the top of the base plate 1. A second motor 73 is fixedly installed on the front of the mounting frame 72. An active roller 74 is fixedly installed at the output end of the second motor 73. The active roller 74 is rotatably installed on the inner side of the mounting frame 72. A driven roller 75 is rotatably installed on the inner side of the mounting frame 72. A transmission belt 76 is provided between the active roller 74 and the driven roller 75 to facilitate the automatic discharge of waste.

[0045] Furthermore, a through groove is provided at the corresponding position of the punch 525 on the processing table 3, and the top of the unloading track 71 corresponds to the position of the through groove, so as to facilitate the automatic discharge of the punching waste.

[0046] In actual operation, when using this device, first pull the stop block 528 outward, so that the stop block 528 drives the sliding shaft 526 to move outward, so that the sliding shaft 526 drives the clamping block 527 to move outward, and at the same time, the clamping block 527 compresses the return spring 529. Then insert the punch 525 from the bottom of the fixed cylinder 522 until the top of the punch 525 contacts the bottom of the mounting plate 521. Then release the stop block 528, and the elastic force of the return spring 529 drives the clamping block 527 to slide inward, so that the clamping block 527 is locked into the groove outside the punch 525, thereby fixing the punch 525.

[0047] The electric push rod 64 drives the connecting platform 65 to move upward, and then the car part body 8 is inserted from the top of the connecting platform 65. During the insertion process, the car part body 8 presses down on the pressing rotating plate 67. After the car part body 8 passes through the pressing rotating plate 67, the spring force of the pulling spring 68 causes the pressing rotating plate 67 to automatically return to its original position. Then, the electric push rod 64 drives the connecting platform 65 to move downward, so that the connecting platform 65 and the pressing rotating plate 67 are pressed tightly against the top of the car part body 8, thereby fixing the car part body 8. Then, the hydraulic rod 511 drives the fixing cylinder 522 to move downward through the connecting plate 512 and the mounting plate 521. When the sliding sleeve 523 contacts the car part body 8, the sliding sleeve 523 is pressed down under pressure. The sliding sleeve 523 slides into the fixed cylinder 522 and compresses the fixed spring 524. The sliding sleeve 523 positions and fixes the car part body 8. Then, the punch 525 is pressed down to perform hole pressing on the car part body 8. After the processing is completed, the hydraulic rod 511 moves upward to separate the punch 525 from the car part body 8. At this time, the sliding sleeve 523 automatically resets to the left and right sides of the fixed spring 524. Then, the first motor 61 drives the rotating shaft 62 to rotate, so that the rotating shaft 62 drives the rotating table 63 to rotate and change position on the top of the processing table 3, so that the car part body 8 rotates and changes position. Then, the above operation is repeated to continue to perform hole pressing on the car part body 8.

[0048] During the pressing process, the waste material is generated and slides down through the unloading track 71 and falls onto the transmission belt 76. The second motor 73 drives the drive roller 74 to rotate, so that the drive roller 74 drives the transmission belt 76 to transmit between the drive roller 74 and the driven roller 75. Thus, the waste material is transported to the right by the transmission belt 76 and automatically falls into the collection box.
