Description

Technical Field

[0001] The present invention is applicable to the technical field of automobile manufacturing equipment, and provides an integrated equipment for cutting and drilling of automobile plastic pipe fittings. Background Art

[0002] Automobile plastic pipe fittings are generally used in scenarios such as engine intake pipes or automobile air-conditioning ducts, and are usually produced by the hollow blow molding process. Since the hollow blow molding process blows air inside the workpiece to form a cavity, except for the air blowing port, the inside of the product is in a closed state. And automobile plastic pipe fittings usually have multiple interfaces. Therefore, after the product is produced in a prototype by the blow molding process, the excess plastic walls at the interface positions need to be cut off so that the interfaces are exposed before it can be put into use. This cutting process is usually carried out by an operator manually or using a cutter to cut each interface in turn, which not only has low efficiency but also lacks cutting accuracy; at the same time, holes need to be drilled in some side wall positions of the pipe fittings. Due to the limitation of the hollow blow molding process, drilling can only be carried out after the product is produced in a prototype by the hollow blow molding process, which further increases the operation process. Summary of the Invention

[0003] Therefore, the present invention provides an integrated equipment for cutting and drilling of automobile plastic pipe fittings. By placing the prototype of the automobile plastic pipe fitting product produced by blow molding on a special positioning tooling, and then performing one-time cutting and drilling operations on multiple positions of the product through a cutting module and an automatic drilling module with preset positions, the operation efficiency is greatly improved, and at the same time, the dimensional accuracy during batch production is ensured.

[0004] To achieve the above object, the present invention provides the following technical solution: An integrated device for cutting and drilling the plastic pipe fittings of an automobile, comprising a device base, an electrical control cabinet, an action control valve group and a device start switch. On the upper end surface of the aforesaid device base, a pipe fitting bottom positioning module, a side pipe orifice cutting module, a bottom pipe orifice cutting module and an automatic drilling module are fixedly arranged. Among them, the pipe fitting bottom positioning module is processed according to the shape of the plastic pipe fitting of the automobile to be processed. The aforesaid side pipe orifice cutting module includes a side cutting module support seat fixedly connected to the upper end surface of the device base. The side cutting module support seat is fixedly connected with a side cutting main driving cylinder. The moving end of the side cutting main driving cylinder is fixedly connected with a driving connecting plate. The aforesaid driving connecting plate is fixedly connected with a first side cutter driving cylinder and a second side cutter driving cylinder. The moving end of the first side cutter driving cylinder is fixedly connected with a first side cutter, and the moving end of the second side cutter driving cylinder is fixedly connected with a second side cutter. The aforesaid bottom pipe orifice cutting module includes a bottom cutting actuating cylinder fixedly connected to the upper end surface of the device base. The moving end of the bottom cutting actuating cylinder is fixedly connected with a bottom cutting connecting plate, and the bottom cutting connecting plate is fixedly connected with a bottom cutter. The aforesaid automatic drilling module includes several side drilling units and several bottom drilling units.

[0005] Further, the side drilling unit includes a side drilling support seat fixedly connected to the upper end surface of the device base. The side drilling support seat is fixedly connected with a side drilling main driving cylinder. The moving end of the side drilling main driving cylinder is fixedly connected with a side drilling needle driving cylinder. The moving end of the side drilling needle driving cylinder is fixedly connected with a side drilling needle. The bottom drilling unit includes a bottom drilling support seat fixedly connected to the upper end surface of the device base. The bottom drilling support seat is fixedly connected with a bottom drilling main driving cylinder. The moving end of the bottom drilling main driving cylinder is fixedly connected with a bottom drilling needle driving cylinder. The moving end of the bottom drilling needle driving cylinder is fixedly connected with a bottom drilling needle.

[0006] Further, the driving connecting plate is also fixedly connected with several product top fixing units, and these product top fixing units are all processed according to the shape of the plastic pipe fitting of the automobile at the corresponding position. Driven by the driving connecting plate, the product top fixing units can be pressed down to the top of the plastic pipe fitting of the automobile, so as to better fix the plastic pipe fitting of the automobile and ensure the cutting and drilling effects.

[0007] Further, the side cutting module support seat is also provided with a side cutting stable track. A side cutting stable slide is slidably connected to the side cutting stable track. The side cutting stable slide is also fixedly connected with the moving end of the side cutting main driving cylinder. The side cutting stable slide can help the operation of the side cutting stable slide to be more stable and avoid the decrease in accuracy caused by the long-term operation of the cylinder.

[0008] Furthermore, a pressure sensor is provided below the side cutting stable slide. The pressure sensor can help detect whether the product top fixing unit accurately fixes the automotive plastic pipe fitting according to the pressure received. If the pressure value is too large, it may be due to reasons such as the product being placed off-position, while if the pressure value is too small, it may be due to reasons such as the product not being placed. Once these situations occur, the equipment will stop working to prevent accidents.

[0009] Furthermore, a number of universal wheels are provided at the lower end of the equipment base, and the equipment start switch is a two-handed start switch. The two-handed start switch requires pressing two start buttons simultaneously for the equipment to start, which greatly avoids the accidental touch situation that may occur with a single-button switch.

[0010] Furthermore, the automotive plastic pipe fitting incision and drilling integrated equipment further includes an air filter. One end of the aforementioned air filter is connected to the air source, and the other end is connected to the action control valve group. The air filter can ensure the smoothness of the air path and will not malfunction after long-term use.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] The side pipe orifice cutting module, bottom pipe orifice cutting module, and automatic drilling module set according to the requirements of the specified automotive plastic pipe fitting can simultaneously complete the interface incision and drilling operations of the automotive plastic pipe fitting as needed, greatly improving the operation efficiency;

[0013] Through the cooperation of the pipe fitting bottom positioning module and several product top fixing units, the automotive plastic pipe fitting can be firmly fixed on the equipment to ensure that it does not move during the operation process. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] The processing process of the side pipe orifice cutting module 2 is as follows: The side cutting main drive cylinder 202 drives the drive connection plate 203 to press down. As the drive connection plate 203 presses down, it will drive the product top fixing unit 208 to abut against the upper part of the automotive plastic pipe fitting 9. The pressure sensor 211 arranged below the side cutting stable slide 210 is used to sense and judge whether the automotive plastic pipe fitting 9 is properly placed.

At the same time, the downward pressing of the drive connection plate 203 will also drive the first side cutter drive cylinder 204 and the second side cutter drive cylinder 205 to reach the specified working positions, and then the first side cutter drive cylinder 204 and the second side cutter drive cylinder 205 will respectively drive the first side cutter 206 and the second side cutter 207 to start cutting the side interface position of the automotive plastic pipe fitting 9;

[0024] The processing process of the bottom pipe orifice cutting module 4 is as follows: The bottom cutting actuating cylinder 401 drives the bottom cutting connection plate 402, and the bottom cutting connection plate 402 drives the bottom cutter 403 to cut the bottom interface position of the automotive plastic pipe fitting 9;

[0025] The processing process of the automatic drilling module 3 is as follows: The side drilling main drive cylinder drives the side drilling needle drive cylinder to approach the drilling position, and then the side drilling needle drive cylinder drives the side drilling needle to drill the specified position of the automotive plastic pipe fitting 9. Similarly, the bottom drilling main drive cylinder drives the bottom drilling needle drive cylinder to approach the drilling position, and then the bottom drilling needle drive cylinder drives the bottom drilling needle to drill the specified position of the automotive plastic pipe fitting 9;

[0026] After the above three processing processes are completed, the side cutting main drive cylinder 202 drives the drive connection plate 203 to lift up, so that the product top fixing unit 208 is separated from the automotive plastic pipe fitting 9. At this time, the entire processing process is completed, and the product can be taken out of the equipment.

[0027] The above is only a preferred embodiment of the present invention.
