Description

Technical Field

[0001] The utility model relates to the field of tooling manufacturing, in particular to a tooling device for drilling processing. Background Art

[0002] Currently, the structure of most commercial 3C products is a single piece of plastic inlaid with copper nails and bonded with a single piece of aluminum. This can supplement the problem of CNC processing for small details and fill the multiple structures in the structure. However, since the plastic and aluminum parts are bonded separately, and the copper nails are integrated into the plastic parts as a single body, the copper nails are a locking structure in the entire product and need to withstand the partial applied force of product flipping and fixing. There is a probability that the bonding will be weak and easy to debond. Therefore, the introduction of aluminum-plastic combined with copper nails makes the product become an integrated structure during production, which can avoid the risk of cracking after being subjected to force. For this reason, it is necessary to be able to flexibly process the copper nail holes.

[0003] At present, the plate hole processing involved in 3C is generally carried out by a drilling machine. The drilling machine needs to use a fixture to position and fasten the workpiece before processing. For drilling holes in 3C plates, a guide sleeve for drilling positions needs to be processed in the fixture. Before processing each workpiece, a dedicated and specific fixture needs to be developed. At a time when 3C product updates and iterations are accelerating, this method has seriously affected the introduction of new products. Utility Model Content

[0004] The purpose of the utility model is to provide a tooling device for drilling copper nails in aluminum-plastic combined molds to solve the above technical problems.

[0005] The technical problem solved by the present invention can be achieved by adopting the following technical solutions:

[0006] The tooling device for drilling copper nails in aluminum-plastic combined molds includes a tooling table, a workpiece positioning mechanism is provided on the tooling table, and the tooling table adopts a metal plate made of magnetic stainless steel as a bearing plate; a mounting mechanism is detachably provided on the side of the tooling table; the mounting mechanism includes a pad, and a sunken surface for fixing the workpiece is provided on the side of the upper end face of the pad facing the center of the tooling table, which is called the mounting surface, and the height of the mounting surface from the upper end face of the pad is 1 to 3 mm less than the thickness of the workpiece, and the height of the mounting surface from the tooling table surface is h; the mounting mechanism also includes a gusset plate, the gusset plate and the pad are perpendicular to each other, the gusset plate is connected to the pad by bolts, and a spring member is also provided between the gusset plate and the pad; the mounting mechanism is connected to the tooling table by bolts; the h is 20 to 30 mm; on the table of the tooling table, a drilling position pad is also connected by magnetism at the position relative to the drilling point, and the drilling position pad is a support pad for supporting the downward pressure of the drill bit on the workpiece when drilling.

[0007] In the utility model, the workbench is provided with a workpiece positioning mechanism for positioning and a mounting mechanism for fixing the workpiece. The workpiece positioning mechanism and the mounting mechanism are provided with a sunken surface for mounting the workpiece on the upper end surface. When the workpiece is set on the sunken surface, part of it protrudes from the upper end surface. The fasteners on the mounting mechanism cover the workpiece, and the workpiece is fixed to the workbench by bolts. The workpiece and the workbench are suspended in the air, and the height of the suspension is the height from the sunken surface to the workbench surface.

[0008] The workpiece is processed into through holes of different sizes by the drill bit. The drill bit exerts downward pressure on the workpiece during processing. Therefore, a drill pad that can play a supporting role needs to be set under each drilling position. The lower end of the drill pad is provided with a magnetic component. The tooling table is made of magnetic stainless steel. The drill pad can be flexibly set on the table surface of the workbench through magnetic suction. This method can adapt to the tooling requirements of new workpieces with different drilling positions, shorten the preparation cycle of tooling equipment, save manufacturing costs, and improve production efficiency.

[0009] Furthermore, the workpiece positioning mechanism includes a right-angle fixing block; the upper end face of the right-angle fixing block is respectively provided with sunken surfaces for positioning the workpiece on two adjacent sides on the side facing the center of the workbench, which are called positioning surfaces. The height of the positioning surface from the upper end face of the right-angle fixing block is less than the thickness of the workpiece by 1 to 3 mm; the height of the positioning surface from the workbench surface is h; the workpiece positioning mechanism is arranged at the corner of the workbench surface.

[0010] In the present invention, two sunken surfaces at right angles to each other are provided on the upper end face of the right-angle fixing block to fix the position of the workpiece and prevent it from moving. The height from the sunken surface to the upper end face is 1 to 3 mm less than the thickness of the workpiece. When the workpiece is placed on the sunken surface, the workpiece protrudes from the upper end face of the right-angle fixing block. This installation of the workpiece is conducive to fixing the workpiece to the mounting pad via fasteners. There is a gap of 20 to 30 mm between the sunken surface and the table top of the workbench. This gap helps prevent the drill bit from hitting the table top after drilling through the workpiece.

[0011] Furthermore, the magnetic stainless steel is at least one of ferritic stainless steel, martensitic stainless steel and duplex stainless steel; the table top of the workbench is provided with threaded holes every 10 mm along the side; and positioning and mounting components with a U-shaped structure are symmetrically provided at the corners of the workbench.

[0012] In this utility model, the workbench, when constructed from at least one of ferritic stainless steel, martensitic stainless steel, and duplex stainless steel, is attracted to magnetic materials. The stronger the magnetism, the more secure the connection between the drill bit and the pad. Threaded holes are provided along the sides of the workbench at 10mm intervals. These holes serve to accommodate mounting mechanisms, which can be flexibly positioned anywhere within the threaded holes, depending on the workpiece.

[0013] Further, the drilling position pad includes a pad with a U-shaped cross-section. The height from the upper end face of the U-shaped pad to the tabletop of the tooling table is h; a magnetic device is fixedly arranged at the lower end of the U-shaped pad.

[0014] In the present utility model, there are usually quite a number of mounting holes appearing at the edge of the sheet metal. This edge position needs to avoid the wall thickness of the drilling position pad itself. Therefore, a drilling position pad with side walls on three sides and one side open is required. The height of the drilling position pad is the same as the distance between the workpiece and the tabletop of the tooling table.

[0015] For further optimization, the width of the area enclosed by the U-shaped pad is 5 - 15 mm, the length is 5 - 30 mm, and the wall thickness of the U-shaped pad is 4 - 6 mm.

[0016] In the present utility model, the size of the area enclosed by the U-shaped pad is suitable for the outer diameter of the drill bit.

[0017] Further, the drilling position pad includes a cylindrical pad. The height from the upper end face of the cylindrical pad to the tabletop of the tooling table is h; a magnetic device is fixedly arranged at the lower end of the cylindrical pad.

[0018] In the present utility model, the cylindrical pad is suitable for the hole positions appearing at non-sheet-metal edges. The height of the drilling position pad is the same as the distance between the workpiece and the tabletop of the tooling table.

[0019] For further optimization, the inner diameter of the cylindrical pad is 5 - 15 mm, and the wall thickness of the cylindrical pad is 4 - 6 mm.

[0020] In the present utility model, the inner diameter size of the cylindrical pad is suitable for the outer diameter of the drill bit.

[0021] Further, the workpiece positioning mechanism is made of at least one of aluminum alloy, polyamide, polycarbonate, polyoxymethylene, polyphenylene ether, and nylon; the mounting mechanism is made of at least one of aluminum alloy, polyamide, polycarbonate, polyoxymethylene, polyphenylene ether, and nylon.

[0022] In the present utility model, the workpiece positioning mechanism and the mounting mechanism made of materials such as aluminum alloy, polyamide, polycarbonate, polyoxymethylene, polyphenylene ether, and nylon have the characteristics of light weight, high strength, and corrosion resistance.

[0023] In the present utility model, on the premise that the workpiece is firmly installed, the drilling pads can be flexibly set according to different hole positions. The drilling pads include U-shaped pads and cylindrical pads, which can adapt to the holes located at the edge of the workpiece and ordinary holes with different diameters. The beneficial effects are reducing manufacturing costs, shortening the production cycle, and improving production efficiency. Description of the Drawings

[0036] Reference Figure 1 、 Figure 3 As shown, a tooling device for drilling copper nails in aluminum-plastic composite molds includes a tooling table 1, on which a workpiece positioning mechanism 3 is provided. The tooling table 1 uses a metal plate made of magnetic stainless steel as a carrier plate; a mounting mechanism 2 is detachably provided on the side of the tooling table 1; the mounting mechanism 2 includes a pad, and a sunken surface for fixing the workpiece is provided on the side of the pad facing the center of the tooling table 1, which is called a mounting surface 20. The height of the mounting surface 20 from the upper end surface of the pad is less than the thickness of the workpiece. 1~3mm, the height of the mounting surface 20 from the table top of the workbench 1 is h; the mounting mechanism 2 also includes a gusset plate, the gusset plate and the pad are perpendicular to each other, the gusset plate is connected to the pad by bolts, and a spring member 22 is also provided between the gusset plate and the pad; the mounting mechanism 2 is connected to the workbench 1 by bolts; the h is 20~30mm; on the table top of the workbench 1, a drilling position pad is also magnetically connected at the position relative to the drilling point, and the drilling position pad is a support pad that supports the downward pressure of the drill bit on the workpiece when drilling.

[0037] In this embodiment, the workbench 1 is provided with a workpiece positioning mechanism 3 for positioning and a mounting mechanism 2 for fixing the workpiece. The workpiece positioning mechanism 3 and the mounting mechanism 2 are provided with a sunken surface for mounting the workpiece on the upper end surface. When the workpiece is set on the sunken surface, part of it protrudes from the upper end surface. The fastener 21 on the mounting mechanism 2 covers the workpiece, and the workpiece is fixed to the workbench 1 by bolts. The workpiece and the workbench 1 are suspended in the air, and the height of the suspension is the height from the sunken surface to the surface of the workbench 1.

[0038] The workpiece is processed into through holes of different sizes by the drill bit. The drill bit exerts downward pressure on the workpiece during processing. Therefore, a drilling pad that can play a supporting role needs to be set under each drilling position. A magnetic component is set at the lower end of the drilling pad. The tooling table 1 is made of magnetic stainless steel. The drilling pad can be flexibly set on the table surface of the workbench through magnetic suction.

The height of the sunken surface from the upper end surface is less than the thickness of the workpiece by 1 - 3 mm. When the workpiece is arranged on the sunken surface, the workpiece protrudes from the upper end surface of the right-angle fixing block. Installing the workpiece in this way is beneficial to fixing the workpiece on the mounting pad by the fastener 21. There is a gap of 20 - 30 mm between the sunken surface and the tabletop of the tooling table 1, and this gap is beneficial for the drill bit to avoid hitting the tabletop of the tooling table 1 after drilling through the workpiece.

[0042] In this embodiment, when the tooling table 1 uses at least one of ferritic stainless steel, martensitic stainless steel and duplex stainless steel as the bearing table, it can attract magnetic bodies, and the stronger the magnetism, the more stable the connection of the drill position pad. Threaded holes are provided every 10 mm along the side of the tabletop of the tooling table 1. The function of the threaded holes is to set the installation mechanism 2, and the installation mechanism 2 can be flexibly set at any place with threaded holes according to different workpieces.

[0044] In this embodiment, there are usually many mounting holes on the edge of the sheet metal. This edge position needs to avoid the wall thickness of the drilling pad itself. Therefore, a drill position pad with side walls on three sides and one side open is required. The height of the drill position pad is the same as the distance between the workpiece and the tabletop of the tooling table 1.

[0045] The width of the area surrounded by the U-shaped pad 4 is 5 - 15 mm, the length is 5 - 30 mm, and the wall thickness of the U-shaped pad 4 is 4 - 6 mm.

[0046] In this embodiment, the size of the area surrounded by the U-shaped pad 4 is suitable for the outer diameter of the drill bit.
