Pocket hole drilling machine

A pocket-hole drilling apparatus for drilling pocket-holes in a workpiece is disclosed. In one embodiment, an initiation switch actuates clamping the workpiece and the movement of a drilling module to cut a pocket-hole. The drilling module has a motor and a step-drill mounted thereon, which is slidably mounted on a guide module. The axis of the drilling module movement intersects work surface. In another embodiment, a movable fence provides the adjustability of pocket-hole depth. In yet another embodiment, two actuator tips are disposed in a fence to prevent the drilling of a pocket-hole through the sidewall of a workpiece. In still another embodiment, a short stroke clamping actuator is used to prevent human finger injury. In still another embodiment, a blower or an ejector pump is used to remove wood chips, wherein the blower is either attached to a drilling motor or to a separate blower motor; the ejector pump is mounted near the drill guide. In still another embodiment, two pocket-drills are slidably mounted on a block so as to drill two pocket-holes and to adjust pocket-hole spacing. In still another embodiment, a mounting structure is disposed either underneath or above the work surface to mount drilling module(s) so as to drill multiple pocket-holes into a wide workpiece at one setup. In still another embodiment, a drill guide forms a clearance for the cutting edges of the step-drill to minimize wear on the edges. In a further embodiment, an actuator provides both clamping and drilling movements, wherein the actuator is an electric motor or a hand lever.

Highly efficient equidistant drilling equipment for furniture plates

The invention discloses highly efficient equidistant drilling equipment for furniture plates. The equipment comprises a base plate, a left side plate, a right side plate, a top plate, a worktable, support legs, a first spring, a power mechanism, clamping devices, a sliding plate and a mounting plate. A third motor, a cam, a fourth motor and a drill bit are mounted on the lower portion of the mounting plate. The arranged power mechanism includes a first electric push rod, a first motor, a driving plate, a driven sheave, a gear and a rack. Through cooperation of the components above to drive theworktable to intermittently and equidistantly move to the left, equidistant drilling is achieved. The arranged clamping device comprises a second motor, a bidirectional lead screw, a vertical plate,an upper clamping plate and a lower clamping plate and can clamp or loose the plates, and clamping is convenient, fast and reliable. The cam and second springs are arranged and cooperate with each other to drive the sliding plate to move up and down, and the sliding plate drives the fourth motor and the drill bit to move up and down, so that drilling is performed on the plates. The equipment is simple in structure, convenient and fast and high in drilling efficiency.

High-accuracy hole forming device for aircraft wall panel and a method of high-accuracy hole forming device

The invention provides a high-accuracy hole forming device for an aircraft wall panel and a method of the high-accuracy hole forming device. A main shaft module is used for feeding an electric main shaft along a hole forming axis; a feeding module is used for guaranteeing movement of the main shaft module and a pressure pin normal leveling module in the hole forming axis and providing pressure for a pressure pin to be abutted against the wall panel; the pressure pin normal leveling module is used for guaranteeing the stability of the wall panel in the hole forming process; the feeding module is matched with a grating scale module for work to realize accurate control over the hole forming feeding displacement; a visual alignment module and a control system form a closed loop feedback loop; positional deviation error of a projection point of a hole forming main shaft on the wall panel surface and an actual hole forming point can be measured and fed back in real time; and correction is performed through the closed loop system to guarantee that the positional accuracy of a formed hole is within a tolerance requirement range. According to the high-accuracy hole forming device, the positional accuracy, the surface roughness and the dimensional accuracy of the hole can meet the design requirements well; and meanwhile, slanting holes and oblique holes are not formed in the hole forming process, the temperature of a hole forming region is kept at a normal working temperature and the chip removal is normal.

Method and device of disposing holes on carbon fiber composite material and meal material which are overlapped

The invention relates to a method and device of disposing high-quality holes on carbon fiber composite material and meal material which are overlapped, belonging to the field of the mechanical processing and manufacturing technology. The method of disposing high-quality holes on the carbon fiber composite material and the meal material which are overlapped is characterized in that in the process of disposing holes on the carbon fiber composite material and the meal material which are overlapped by a device of disposing holes, such as a polycrystalline diamond (PCD), a coating, a cemented carbide bit and a diamond grinding rod, the rotating speed and the feeding speed of a cutter are automatically changed according to the materials on which holes are to be disposed by the hardware triggering or software numerical-control programming control mode of a feeding position sensor set so that the cutter can be in the optical process parameter state. The device of disposing high-quality holes on the carbon fiber composite material and the meal material which are overlapped is characterized by comprising a body, the cutter the handle of the cutter, an electric main shaft, the feeding position sensor set, a vertical feeding sliding-platform, a main shaft variable-frequency speed-regulating system and a hole disposing device numerical control system. The invention realizes the adaptive continuous processing, obviously improves the quality and the processing efficiency of holes disposed integrally on different overlapped materials and lowers the production cost.
