Abstract
The utility model discloses an inner hole forming device of a tungsten steel double straight hole round bar, which includes a center drill and a V-shaped groove bed which is arranged corresponding to a machining position of a drill bit of the center drill; the center drill and the V-shaped groove bed are disposed on a frame; the V-shaped groove bed is slidably disposed on the frame along an axial direction of the drill bit by means of a sliding guide rail; a tungsten steel workpiece is fixed in a V-shaped notch of the V-shaped groove bed; and a diamond is electroformed on the drill bit of the center drill. As compared with the conventional device of a long working procedure and with the drill bit that is easy to wear, the center drill especially adapted for machining of a center hole in an end face of the shaft workpiece is adopted in the inner hole forming device of the tungsten steel double straight hole round bar provided by the utility model; the center drill works in conjunction with the sliding V-shaped groove bed used for fixation of the tungsten steel workpiece so as to greatly increase work efficiency; and the drill bit with the electroformed diamond facilitates prolongation of service life of the drill bit and cost reduction.
Description
Technical field
The utility model relates to a kind of pin assembly that mills, and especially refers to a kind of drilling equipment of wolfram steel double straight-hole ball rod.
Background technology
At present, the endoporus forming processing device of wolfram steel double straight-hole ball rod is as shown in Figure 1, and the wolfram steel workpiece 3 ' that cuts into small plate is fixed on the CNC CNC milling machine with vice 2 '; Programmed then; Choose drill bit 1 ', with the drill bit 1 ' handle of a knife of packing into, handle of a knife refills on the CNC CNC milling machine; To good zero point, last start-up routine.Adopt above-mentioned CNC CNC milling machine boring procedure to waste a lot of times, the general long ball rod of 1PCS200mm will bore the few 2H of 2 Kongzuis; And the drill bit waste is big, and 1PCS ball rod need be used 2 drill bits, and production cost is high.
The utility model content
To the weak point that exists in the prior art, the utility model provides a kind of novel excellent interior hole forming equipment of wolfram steel double straight-hole ball.Adopt this device not only to shorten operation, and significantly provide cost savings, efficient improves greatly.
For realizing above-mentioned purpose, the utility model technical scheme is:
The interior hole forming equipment of wolfram steel double straight-hole ball rod; This device comprises the centre drill that is arranged on the frame and a pair of V-type groove seat that is provided with of Working position that should the centre drill drill bit; This V-type groove seat through a sliding guide rail device along the drill bit axial slip on frame, the wolfram steel workpiece is fixed in the V-type notch of V-type groove seat.
Further, electroforming diamond on the drill bit of centre drill.
The usefulness of technique scheme is:
Long with operation in the prior art; The endoporus forming processing device of the wolfram steel double straight-hole ball rod that the drill bit loss is big is compared; The interior hole forming equipment of the utility model wolfram steel double straight-hole ball rod adopts the centre drill that is particularly suitable for the processing of shaft-like workpiece end face centre bore; Cooperate the slip V-type groove seat that is used for fixing the wolfram steel workpiece, can improve work efficiency greatly.And the drill bit of electroforming diamond has improved the service life of drill bit, provides cost savings greatly.
