Abstract
The utility model discloses an annular groove machining tool for a vertical drill. The annular groove machining tool for the vertical drill comprises a tool bar, wherein a limiting nut is connected to the middle part of the tool bar; a core shaft sleeve is fixedly connected to the lower part of the tool bar; a tool disc is installed at the bottom of the tool bar; tool bits are symmetrically installed at the bottom of the tool disc; a casing is supported on the outer circle of the core shaft sleeve through a bearing; and a three-claw positioning sleeve is fixedly connected to the bottom of the casing. The annular groove machining tool for the vertical drill can machine annular grooves with six sizes, along with good size consistency and easy precision control; machined components are convenient to replace, and the assistant time for replacing the machined components is short; the machined components can be positioned conveniently and precisely; the depths of the annular grooves are not influenced by the integral thickness of a hydraulic valve; the labor intensity is low and the production efficiency is high; and compared with the annular grooves machined on a lathe, the quality of the annular grooves machined by the annular groove machining tool for the vertical drill is easily ensured and the production efficiency can be improved by 2 to 3 times.
Description
Technical field
The utility model relates to a kind of process tool of annular groove, particularly relates to a kind of annular groove process tool that is used for vertical drill.
Background technology
At present, the closure gasket groove of hydraulic pressure valve block class adopts machined into usually.Adopt the machined into closure gasket groove to have following technical problem: 1) degree of depth of annular groove is wayward, and is often defective because of the depth dimensions of annular groove, causes scrapping of whole hydraulic pressure valve block, thereby reduced the yield rate of hydraulic pressure valve block; 2) closure gasket groove of processing hydraulic valve block class on lathe, the workpiece difficulty that is installed is big, and the time is long; 3) degree of depth of annular groove receives the thick influence of sheet bigger, causes depth dimensions inconsistent easily.Longer to the sheet adjustment time, cause working (machining) efficiency lower; 4) closure gasket groove of processing hydraulic valve block class on lathe, the skilled worker who needs higher level comes milling cutter, and skilled worker's technical merit is had relatively high expectations; 5) closure gasket groove of processing hydraulic valve block class on lathe, labour intensity is big, and production efficiency is low.
The utility model content
The utility model provides a kind of annular groove process tool that is used for vertical drill for solving the technical problem that exists in the known technology, on vertical drill, uses the closure gasket groove of this process tool processing hydraulic valve block class, and easy and simple to handle, efficient is high, and yield rate is high.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of annular groove process tool that is used for vertical drill; Comprise knife bar; The middle part of said knife bar is connected with spacing locknut; The bottom of said knife bar is connected with core sleeve, and cutterhead is equipped with in the bottom of said knife bar, and the cutter head of symmetric arrangement is equipped with in said cutterhead bottom; Be supported with overcoat through bearing on the cylindrical of said core sleeve, the bottom of said overcoat is connected with the three-jaw positioning sleeve.
Said spacing locknut is provided with opening, and said opening is through clamping screw locking.
Said cutter head is provided with radially adjusts screw.
Advantage and the good effect that the utlity model has are:
1) can once accomplish the processing of six sizes of annular groove, and the high conformity of size, precision is easy to control;
2) adopt this cutter on vertical drill, to process annular groove, can manually compress part to be processed voluntarily, do not need hold-down mechanism; When changing part to be processed, do not need to loosen specially part to be processed, only need loose one's grip and can take out part to be processed, the replacing of part to be processed is convenient, and the non-cutting time of changing part to be processed is short;
3) be convenient to location and accurate positioning;
4) the groove depth size does not receive the influence of hydraulic pressure valve block integral thickness;
5) adopt this cutter on vertical drill, to process annular groove, labour intensity is low, and production efficiency is high.
In sum, the utility model is compared with processing annular groove on lathe, and not only quality guarantees easily, and production efficiency also can improve 2～3 times.
Description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the upward view of Fig. 1.
Among the figure: 1, alignment pin, 2, chamfering, necking cutter bit, 3, cutterhead, 4, core sleeve, 5, overcoat, 6, spring, 7, spacing locknut, 8, knife bar, 9, clamping screw, 10, the three-jaw positioning sleeve, 11, radially adjust screw.
The specific embodiment
For further understanding summary of the invention, characteristics and the effect of the utility model, the following examples of giving an example now, and conjunction with figs. specifies as follows:
See also Fig. 1～Fig. 2; A kind of annular groove process tool that is used for vertical drill; Comprise knife bar 8, the middle part of the said knife bar 8 spacing locknut 7 that has been threaded, the lower thread of said knife bar 8 is connected with core sleeve 4; Cutterhead 3 is equipped with in the bottom of said knife bar 8, and chamfering, the necking cutter bit 2 of symmetric arrangement is housed on the said cutterhead 3; The top of said cutterhead 3 is provided with the holddown spring 6 that is contained in the knife bar centre bore; Be supported with overcoat 5 through bearing on the cylindrical of said core sleeve 4, the bottom of said overcoat 5 is connected with three-jaw positioning sleeve 10, and the bottom of three-jaw positioning sleeve 10 is provided with alignment pin 1.In the present embodiment, said spacing locknut 7 is provided with opening, and said opening is through clamping screw 9 lockings.Said cutter head is provided with and radially adjusts screw 11.This cutter adapts to the needs of processing different depth annular groove through the position of regulating spacing locknut 7.Radially adjust the needs that screw 11 adapts to two circle different-diameters inside and outside the annular groove through regulating, chamfering, necking cutter bit should be adaptive with annular groove chamfering and width.
The operation principle of the utility model:
Handle of a knife is connected on the main shaft of upright drill through the Morse drill holder; Start back main axis rotation also moves down, and when processing the annular groove on the sheet class part end face, locatees with the three-jaw positioning sleeve; After alignment pin inserts the locating hole on the sheet class part; After the bottom surface of alignment pin was adjacent to the bottom surface of part to be processed locating hole, the three-jaw positioning sleeve of overcoat and band alignment pin stopped the rotation, and the three-jaw positioning sleeve plays the effect that compresses part to be processed; Machine spindle drives knife bar, spacing locknut, core sleeve, cutterhead and cutter head and continues to rotate and move down, and when spacing locknut was adjacent to overcoat, main shaft no longer moved down, and once accomplished part processing.
The utility model is suitable for the annular groove on the common vertical drill processing parts end face, and it can the disposable degree of depth with annular groove, six size time processing of two diameter of a circles put in place inside and outside chamfering, annular groove width and the annular groove on inside and outside two circles.Machining accuracy, diametric(al) can be controlled in the 0.06mm, and depth dimensions can be controlled in the 0.05mm, and width can be controlled in the 0.03mm.Can guarantee the dimension precision requirement of hydraulic pressure valve block closure gasket groove fully.
