The utility model content
The purpose of the utility model provide a kind of can to cylindrical sleeve fast, the accurate drilling tool of location, add the problem that man-hour, cylindrical sleeve can't be located in order to solve boring.
The utility model adopts following technical scheme: a kind of drilling tool that is used for cylindrical sleeve; Comprise clamp body; Offer the blind hole that is used to hold cylindrical sleeve of extending forward on the rear end face of clamp body; Offer the duct of running through said clamp body of the axis spatial vertical of axis and said blind hole on the outer wall of clamp body, the rear end of said clamp body is equipped with through retaining mechanism and is used for the latch of cylindrical sleeve roof pressure at blind-hole bottom.
Said latch is provided with the detent mechanism that is used for latch location, and said detent mechanism comprises the alignment pin that is inserted on the clamp body rear end face, and said alignment pin is used for direct or indirect latch being positioned at clamp body.
The degree of depth of said clamp body blind hole is fixed with location-plate greater than the cylindrical sleeve height on the rear end face of said latch, and said alignment pin is used for location-plate is positioned at clamp body.
Said retaining mechanism comprises the lock shaft along the extension of clamp body axial direction on the front end face that is fixed on latch; Has the gap that is used to be provided with cylindrical sleeve between lock shaft and the said clamp body; Said lock shaft stretches out said clamp body through the through hole that extends forward that is opened on the clamp body blind-hole bottom face, and the clamp body part of stretching out of lock shaft is equipped with the locking locking nut that is used to lock cylindrical sleeve through screw thread.
Said lock shaft is a multidiameter, and the enlarged diameter section of lock shaft and said latch are connected, and the reduced diameter section of said lock shaft has screw thread.
Adopt the drilling tool of said structure, offer the blind hole of placing cylindrical sleeve on the clamp body of this frock, latch is used for cylindrical sleeve is locked in the clamp body; Thereby through retaining mechanism latch being applied thrust is fixed in the clamp body cylindrical sleeve; Simple in structure, easy to operate, can realize locking fast to cylindrical sleeve; The position of positioning hole to be processed place of corresponding circle column sleeve offers the duct of running through clamp body on clamp body; Rely on this passage can directly confirm the position of positioning hole to be processed of cylindrical sleeve, accurate positioning has improved the boring working (machining) efficiency of cylindrical sleeve.

The specific embodiment
As shown in Figure 1; A kind of embodiment that is used for the drilling tool of cylindrical sleeve of the utility model: this frock is made up of clamp body 3, latch 6, retaining mechanism and detent mechanism; Offer forward the blind hole adaptive of extending on the rear end face of clamp body 3 with cylindrical sleeve to be processed 5; During assembling, cylindrical sleeve 5 is inserted in the blind hole of clamp body 3, and the degree of depth of blind hole is greater than the height of cylindrical sleeve 5 to be processed.The front end face of said latch 6 cooperates with the rear end face roof pressure of cylindrical sleeve 5; Its roof pressure cooperates through retaining mechanism to be realized; Retaining mechanism has the lock shaft 4 that extends along the blind hole axial direction; Said lock shaft 4 is a multidiameter, and the enlarged diameter section 42 of lock shaft 4 is fixed on the front end face of latch 6, and enlarged diameter section 42 and inwall matched in clearance cylindrical sleeve 5 to be processed; The blind-hole bottom of clamp body 3 offers through hole; The reduced diameter section 41 of lock shaft 4 extends forward and passes this through hole; And the reduced diameter section 41 of lock shaft 4 is provided with screw thread, realizes that through being located at the locking nut 1 that lock shaft 4 stretches out on clamp body 3 parts latch 6 compresses cylindrical sleeve 5 to be processed, also is provided with pad 2 between locking nut 1 and the clamp body; In specific operation process, tighten locking nut 1 with the bottom of cylindrical sleeve 5 roof pressures to be processed in blind hole.The drill bit work of drilling machine for ease; Offer the duct of running through clamp body 3 on the outer wall of said clamp body 3; Spatially perpendicular to the axis of blind hole, this duct is consistent with the locating hole that cylindrical sleeve 5 to be processed will be processed for the axis in duct, simultaneously can be through the enlarged diameter section 42 of lock shaft 4 for drill bit; Position, corresponding duct offers groove on the enlarged diameter section 42, and passage and groove all are passing through for the ease of the drilling machine drill bit.Said detent mechanism comprises latch 6 is positioned at the alignment pin 8 on the clamp body 3; Because the degree of depth of blind hole is greater than the height of cylindrical sleeve 5; The location-plate inconvenience directly is positioned on the clamp body 3; Therefore, stipulate on the rear end face of latch 6 that has location-plate 7, alignment pin 8 passes location-plate 7 latch 6 is assemblied on the clamp body 3.
In other embodiments, said retaining mechanism can also adopt other structure, and fixed flange on clamp body 3 is realized the locking of 6 pairs of cylindrical sleeve 5 of latch through on ring flange and location-plate, wearing clamping screw, and alignment pin 8 need not be set.
In the foregoing description; The degree of depth of said clamp body 3 blind holes is greater than the height of cylindrical sleeve 5; In other embodiments, the degree of depth of said blind hole can directly be arranged in alignment pin 8 on the latch 6 less than the height of cylindrical sleeve 5 like this; Realize the direct location of latch 6 on clamp body 3, and location-plate 7 need be set.
The embodiment of the utility model is sleeved on cylindrical sleeve 5 on the lock shaft 4 earlier when concrete the use, and the lock shaft 4 that cylindrical sleeve 5 will be housed is then packed in the clamp body 3 together; Load onto alignment pin 8 and pad 2 and locking nut 1 more respectively; Tighten locking nut 1, promptly accomplish the locking of cylindrical sleeve 5 to be processed, add man-hour; The drilling tool that installs cylindrical sleeve 5 is placed on the workbench of drilling machine, the duct on the drill bit clamp body of drilling machine just can be processed.
