A kind of endoporus knife rest centralized positioning holder structure; It includes: socket main body and a holder and a locking lock, and this socket main body is a tubular body, and plugs in the center and to be fixed with the center tool rest; Be fixed with cutter within this center tool rest; It is characterized in that: this socket main body is held level with both hands to cut at one of outer tube wall and is formed with the joint portion, and the dual-side of this joint portion inwardly contracts and form sliding edge, and this holder cooperates this joint portion and has been recessed to form engagement groove; And this holder combines this clamping block at the upper end of engagement groove; The other end at engagement groove is provided with a fixed part again, and this joint portion is slidingly installed in the engagement groove of this holder, and props up the dual-side of this engagement groove with the interior sliding edge that contracts.
Preferably, equidistance offers a plurality of screws on this clamping block, and bolt passes screw and is locked on the fixing hole of holder, adjusts the size of engagement groove through the locking degree of clamping block.
Preferably, this cutter can be internal lathe-tool, drill bit or external diameter lathe tool.
Preferably, this socket main body is locked and is provided with the bolt of a plurality of fixed center tool rest use.
With respect to prior art; The socket main body that the described knife rest fixed seat structure of the utility model is comprised can cooperate different cutters to be processed into different sizes and internal diameter; Be shape disconnected from each other through socket main body and holder; Make the socket main body of different size all can cooperate same holder, thereby can reduce the material cost and the processing cost of socket main body.

Embodiment
To combine accompanying drawing below, so that the described knife rest fixed seat structure of the utility model is elaborated.
Please one consult Fig. 1 and shown in Figure 2; The described endoporus knife rest of the utility model centralized positioning holder structure is made up of a socket main body (10) and a holder (20), and this socket main body is a tubular body, and plugs in the center and to be fixed with center tool rest (11); The internal fixation of tool rest (11) has cutter (12) in the center again; In addition, one of this socket main body (10) outer tube wall is held level with both hands to cut and is formed with a joint portion (13), and the dual-side of joint portion (13) inwardly contracts and forms sliding edge (131).
This holder (20) cooperates the joint portion (13) of this socket main body (10) to be recessed to form engagement groove (21); In the present embodiment; This holder (20) is combined with a clamping block (22) at the upper end of engagement groove (21); Whether lock through this clamping block (22), promptly can adjust the size of engagement groove (21).In addition, the other end at this engagement groove (21) is provided with a fixed part (23).
Please consult Fig. 2,3,4 together; This holder (20) has a clamping block (22) in the end locking of this engagement groove (21); And this clamping block (22) is gone up equidistance and is offered a plurality of screws (221), therefore bolt (222) can be provided, and makes it pass screw (221) and is locked on the fixing hole (211) of holder (20); Through the locking degree of bolt (222), change the size of engagement groove (21).In addition; Hold level with both hands to cut at the tube wall one of this socket main body (10) and be formed with a joint portion (13); This joint portion (13) is slidingly installed in the engagement groove (21) of this holder (20), and props up the dual-side of engagement groove (21) with the interior sliding edge that contracts (131), makes this socket main body (10) can't be directly by taking out in the engagement groove (21) of holder (20); Lock start by bolt (222) end of clamping block (22) again; Clamping block (22) is approached to holder (20) end, reduce the size of engagement groove (21) thus, reach socket main body (10) is carried out sealed fixing effect.Further; Can plug center tool rest (11) in the center of socket main body (10), and at the center center fixed cutting tool (12) of tool rest (11), in the present embodiment; This cutter (12) can be internal lathe-tool, drill bit or external diameter lathe tool; In addition, locking in this socket main body (10) is provided with the bolt (111) that a plurality of fixed center tool rests (11) use, and should accomplish the assembling of knife rest centralized positioning holder structure thus.
See also Fig. 4 and Fig. 5, in actual use, the described knife rest centralized positioning of the utility model holder structure can be applicable on lathe or the CNC lathe; Figure is the signal that general lathe is shown, owing to cooperate hole within the turning processing object, it must use socket main body (10) and holder (20) to increase the structural strength of cutter (12); And can reach the adjustment of extending cutter (12) length and height, wherein, the fixed part (23) of holder (20) is locked on the toolframe (30) of lathe; Engagement groove (21) through holder (20) carries out sealed to the joint portion (13) of socket main body (10); Can cutter (12) be fixed on the toolframe (30), when desiring to carry out cutter (12) replacement, directly unclamp the bolt (222) that is positioned on the clamping block (22); And extract socket main body (10) out by the side openings of engagement groove (21); Through replacing the action of different socket main bodys (10), can reach the effect of quick replacing cutter (12), reduce the time of changing cutter (12).
In sum; The described knife rest centralized positioning of the utility model holder structure has following benefit: its socket main body (10) can cooperate the difference of cutter (12) and process different sizes and internal diameter; Be shape disconnected from each other through socket main body (10) and holder (20); Make the socket main body (10) of different size can both cooperate same holder (20), thereby can reduce the material cost and the processing cost of socket main body (10).
Need to prove; The utility model is not limited to above-mentioned embodiment; Creative spirit according to the utility model; Those skilled in the art can also make other and change, the variation that these are done according to the creative spirit of the utility model, all should be included in the utility model scope required for protection in.
