Description

Technical Field

[0001] This utility model relates to the field of product processing tooling, and in particular to an adjustable angle drilling tooling. Background Technology

[0002] In existing technology, high-voltage connector panels for automotive parts have multiple holes for connection with other components, requiring drilling equipment to drill holes at multiple locations. Because the high-voltage connector panel has multiple faces with different angles, drilling must be performed to match the angles of these faces. Furthermore, existing drilling techniques require fixing the high-voltage connector panel for precise positioning, necessitating the use of tooling to secure it.

[0003] Existing workpiece drilling fixtures require removing the workpiece from the fixture and adjusting the angle before drilling when drilling multiple angle surfaces. This process is very time-consuming and labor-intensive. Therefore, it is necessary to design a drilling fixture that can adjust the angle to eliminate the need for repeated workpiece disassembly and adjustment.

[0004] In addition, since the same mold core is inconvenient for drilling different workpieces, it is necessary to design a structure that can be easily adapted to the assembly of various different workpieces. Utility Model Content

[0021] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0022] like Figures 1 to 5 The present invention preferably provides an adjustable angle drilling fixture, including a fixture base 1, a support plate 2 for placing a workpiece on the fixture base 1, a rotating structure 3 for rotating the support plate 2 at a fixed point on the fixture base 1, a lifting structure 4 for adjusting the angle of the support plate 2 along the rotation point, a bottom mold 5 that can be replaced according to the workpiece on the support plate 2, and a clamping structure 6 for fixing the workpiece.

[0023] This adjustable-angle drilling fixture is specifically designed for high-pressure insert panels in automotive parts, and can also be used for drilling other workpieces. In use, the workpiece is placed on the bottom mold and clamped in place by the clamping structure. Drilling can then be performed. When the workpiece angle needs to be adjusted, the lifting structure is activated, and under the action of the rotating structure, the bottom mold and support plate can be adjusted in angle, allowing the workpiece on the bottom mold to be drilled at different angles.

[0024] The rotating structure 3 described in this utility model includes two columns 31 disposed on the front side of the top of the tooling base 1. A rotating support 32 is disposed on the top of the columns 31. A rotating shaft 33 is horizontally inserted into the two rotating supports 32. Several shaft clamps 34 are disposed at the bottom front side of the support plate 2 and are fixedly connected to the rotating shaft 33. The rotating shaft can rotate on the rotating support, so the shaft clamps that clamp the rotating shaft can rotate. Since the shaft clamps are fixedly installed at the bottom of the support plate, the support plate and the bottom mold on it can be adjusted by flipping.

[0025] The rotating structure 3 of this utility model also includes two uprights 35 disposed on the rear side of the top surface of the tooling base 1. A side groove 36 is provided on the facing side of the two uprights 35. The rear end of the support plate 2 is positioned between the two side grooves 36 for limited rotational movement. The side grooves of the two uprights are symmetrical and face each other, allowing the rear end of the support plate to move within them. When the angle of the support plate is adjusted, its highest position can touch the top wall of the side groove, and its lowest position can touch the bottom wall of the side groove, thereby limiting the rotation angle limit of the support plate. The uprights are fixed with bolts, and the user can replace the uprights to allow the size of the side grooves to be changed according to the workpiece requirements.

[0026] The lifting structure 4 described in this utility model includes a lifting base 41 disposed on the top surface of the tooling base 1. An electric push rod 42 is hinged to the lifting base 41. A through hole 43 is provided on the support plate 2 above the electric push rod 42. The movable end of the electric push rod 42 passes through the through hole 43, and a lifting top connecting seat 44 is hinged to the top of the movable end of the electric push rod 42. When the electric push rod is activated, the movable end pushes upward, thereby allowing the bottom mold to be angled. The lifting base and the lifting top connecting seat are both hinged to the electric push rod, so that the movable end automatically adapts and rotates during the extension process. The through hole allows the movable end to contact the bottom mold directly for pushing, thereby causing the support plate to rotate accordingly. The extension data of the electric push rod can be controlled by connecting to an external CNC device or control console.

[0027] The bottom mold 5 of this invention includes four fixed supports 51 disposed on the top of the support plate 2. A lower template 52 is provided on the top of each fixed support 51, and a mold core 53 for stably placing the workpiece is provided on the top of the lower template 52. The lower template 52 and the mold core 53 are connected by bolts. The fixed supports are fixed between the support plate and the lower template, allowing them to rotate synchronously. The mold core is bolted together, thus allowing for replacement. By adapting the mold core to different workpieces, this fixture can be used with various workpieces.

[0028] In this invention, the lifting top connecting seat 44 is fixedly connected to the bottom of the lower template 52. The movable end of the lifting top connecting seat and the electric push rod is hinged, so the lifting top connecting seat and the movable end adapt to each other when the lower template rotates.

[0029] The clamping structure 6 described in this utility model includes cylinders 61 disposed on the front and rear sides of the support plate 2. A pressure rod 62 is hinged to the top of the movable end of the cylinder 61. A hinge member 63 is disposed on the body of the cylinder 61. A connecting rod 64 is hinged between the hinge member 63 and the pressure rod 62. When the cylinder is activated, the movable end pushes one end of the pressure rod upward. Since the hinge member tightens the middle section of the pressure rod through the connecting rod, the other end of the pressure rod will press downward, thereby fixing the workpiece on the mold core. When one end of the pressure rod is pushed upward by the movable end of the cylinder, the hinge member and the connecting rod will adapt to the movement, making the pressure rod rotate smoothly.
