Technical Field
[0001] This invention relates to the field of drilling technology, specifically to a multi-hole positioning drilling machine for automotive seat lock tongues. Background Technology
[0002] With technological advancements and economic development, automobiles, especially sedans, are becoming increasingly common, and people are relying more heavily on them for transportation. Consequently, the automotive industry is developing rapidly, driving the growth of related industries such as the auto parts industry. A car seat lock, typically referring to the locking mechanism of an adjustable seat, has a locking tongue as its core force-bearing and engaging component. This tongue is usually installed on the seat back and works with a latch on the seat frame to lock and adjust the seat back angle, ensuring that the seat back does not move arbitrarily when locked. It is usually made of high-strength steel sheet through stamping or precision casting, and has a complex shape. It requires the machining of multiple high-precision positioning holes (such as mounting shaft holes, guide holes, and spring pin holes). The positional accuracy, dimensional precision, and consistency of these holes directly determine the smoothness of the engagement between the locking tongue and the locking plate, the locking strength, and the safety, reliability, and noise-free performance of the entire seat system.
[0003] Chinese patent CN105081395B discloses a multi-hole automatic drilling machine, including a frame, an operating table mounted on the frame, and a drill bit mechanism. The drill bit mechanism is located above the operating table. At least one of the two components, the operating table and the drill bit mechanism, is vertically and flexibly mounted on the frame. The machine also includes multiple clamping components fixed to the upper surface of the operating table, which clamp the workpiece to be drilled onto the upper surface of the operating table. The drill bit mechanism includes a mounting base and drill bits vertically mounted on the mounting base. The number of drill bits and mounting bases corresponds one-to-one. The drill bits are rotatably mounted on the mounting base around their own axis. The automatic drilling machine also includes a power mechanism for driving the drill bit movement and a synchronization mechanism located between all the drill bits for driving the drill bits to rotate synchronously. This drilling machine has a simple structure, can simultaneously drill multiple holes in a workpiece, saves manpower, ensures personal safety, improves drilling efficiency, and ensures consistent spacing between holes, facilitating installation. When drilling multiple holes in a workpiece, this device cannot adjust the hole positions in multiple directions according to processing requirements, and it cannot clamp and fix irregularly shaped workpieces of different sizes.
