Technical Field

[0001] This utility model relates to the field of hole-making technology for parts, and in particular to a hole-making device for parts manufacturing. Background Technology

[0002] Machinery manufacturing refers to the industrial sector engaged in the production of various power machinery, lifting and transportation machinery, chemical machinery, textile machinery, machine tools, tools, instruments, meters, and other mechanical equipment. The machinery manufacturing industry provides technical equipment for the entire national economy. Drilling devices are commonly used in machinery manufacturing. Drilling devices are a collective term for machinery and equipment that use tools harder and sharper than the target object to create cylindrical holes or openings in the target object through extrusion or rotation. They play a very important role in mechanical operations.

[0003] However, existing patents have the following drawbacks:

[0024] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this disclosure. Rather, they are merely examples of apparatuses consistent with some aspects of this disclosure as detailed in the appended claims.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Example 1:

[0027] like Figures 1 to 8 As shown, a component manufacturing opening device includes:

[0028] A fixed base plate 1 has fixed holes at its four corners. A support frame 2 is fixedly connected to the top of the fixed base plate 1. A support column 3 is fixedly connected between the bottom of the support frame 2 and the fixed base plate 1. A placement platform 4 is fixedly connected to the top of the fixed base plate 1. A discharge hole 5 is opened at the top of the placement platform 4. A discharge groove is opened on the front side of the placement platform 4. A hole-opening tool holder assembly 6 is set on the outside of the support column 3. A positioning assembly 7 is set on the outside of the support column 3. A hydraulic rod 8 is fixedly connected to the bottom of the support frame 2.

[0029] The positioning assembly 7 includes: a second connecting pipe 701, a connecting plate 702, a positioning bolt 703, a second spring 704, and a fixed shaft 705. A sliding groove 706 is provided on the outer side of the support column 3. The fixed shaft 705 is fixedly connected to the inner side of the sliding groove 706. The second connecting pipe 701 is slidably connected to the inner side of the sliding groove 706. The second connecting pipe 701 is slidably connected to the fixed shaft 705. The connecting plate 702 is fixedly connected to the outer side of the second connecting pipe 701. The positioning bolt 703 is fixedly connected to the bottom end of the connecting plate 702. A positioning hole 709 is provided at the top of the tool holder disc 601. The positioning bolt 703 is slidably connected to the positioning hole 709. The second spring 704 is fixedly connected between the sliding groove 706 and the second connecting pipe 701.

[0030] A limiting protrusion 707 is fixedly connected to the inner side of the connecting pipe 701, and a limiting groove 708 is opened on the outer side of the fixed shaft 705. The limiting protrusion 707 and the limiting groove 708 are slidably connected. The limiting protrusion 707 and the limiting groove 708 cooperate to prevent the connecting pipe 701 from rotating.

[0031] The punch holder assembly 6 includes: a punch holder disk 601, a connecting tube 602, an extrusion column 603, a punching knife 604, and a spring 605. The punch holder disk 601 is rotatably connected to the outside of the support column 3. There are several connecting tubes 602, which are fixedly connected to the bottom of the punch holder disk 601. The extrusion column 603 is slidably connected to the inside of the connecting tube 602. The punching knife 604 is fixedly connected to the bottom of the extrusion column 603. There are a total of eight punching knives 604, and the eight punching knives 604 have different hole diameters, which can be used to punch holes of different diameters. The spring 605 is fixedly connected between the connecting tube 602 and the extrusion column 603.

[0032] The top of the tool holder 601 has an insertion hole 606. The bottom end of the connecting pipe 602 is fixedly connected to a limiting protrusion 607. The outer side of the extrusion column 603 has a limiting groove 608. The limiting protrusion 607 and the limiting groove 608 are slidably connected. The limiting protrusion 607 and the limiting groove 608 cooperate to prevent the extrusion column 603 from rotating when making the hole, and at the same time, to ensure the stability of the hole.

[0033] In practical use, pulling the connecting plate 702 upwards causes the connecting tube 701 to slide in the groove 706, while the positioning bolt 703 is removed from the positioning hole 709 at the top of the tool holder disk 601, at which point the tool holder disk 601 is unlocked and rotated.

[0034] Rotate the tool holder disk 601, select the required hole-opening knife 604 according to the needs, adjust it to be directly above the discharge hole 5 of the placement table 4, then loosen the connecting plate 702. The second spring 704 pushes the second connecting tube 701, so that the connecting plate 702 drives the positioning bolt 703 to press down and insert it into the positioning hole 709 of the tool holder disk 601, locking the tool holder disk 601 and preventing it from rotating when opening holes.

[0035] Place the part requiring drilling on the top of the placement platform 4, activate the hydraulic rod 8, insert the drive end of the hydraulic rod 8 into the insertion hole 606 at the top of the tool holder 601, push the extrusion column 603 down in the connecting pipe 602, so that the drilling knife 604 presses down on the part and completes the drilling on the surface of the part. Control the hydraulic rod 8 to retract, and the spring 605 pushes the extrusion column 603 to rise and reset. The waste material from the drilling falls from the discharge hole 5 into the discharge trough and is discharged.

[0036] The hydraulic rod in the device is connected to an external hydraulic system. Since the hydraulic system is common knowledge in the field and is not an improvement in this case, it will not be described in detail here.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
