The slot tool bar is an L-shaped bar which comprises a horizontal rectangular bar and a vertical bar tip which is located at the left end of the rectangular bar and is vertical to the rectangular bar; the front end of the upper surface of the bar tip is provided with an open slot penetrating through the left end; one end of a blade is horizontally arranged in the open slot; a pressing plate is abutted in the front of the blade; the pressing plate is fixedly connected with the slot tool bar through a bolt; a wedge-shaped block is welded on the upper surface of the rectangular bar; the front end face and the rear end face of the wedge-shaped block are respectively on the same plane with the front end face and the rear end face of the rectangular bar; and the upper surface of the wedge-shaped block is an angular surface inclining towards the bottom left. By adopting the end face angle T-slot tool, the defect that one tool is adopted from different angles to correspond to cushion blocks with different angles to carry out multiple trial cut and coordinate measuring machine (CMM) frequent detection processing in the past is overcome, the problems of slot base gear marks, surface toughness and low dimensional precision are thoroughly solved, the processing precision and the processing efficiency are improved and the cost is reduced.

Description

End plane angle T groove cutter

Technical field

The utility model relates to the machine tool technical field, especially a kind of used cutter of angle T type groove of processing the butterfly type valve end face.

Background technology

As shown in Figure 1, partial structurtes schematic diagram for the U.S. A11/31/41 of FISHER company series high-performance butterfly type valve, comprise valve body 1 ' and butterfly plate 2 ', valve body 1 ' is gone up and there is a key position angle T type groove 3 ' butterfly plate 2 ' sealing contact position, this T type groove 3 ' cooperates the metal o-ring 4 ' sealing of pressurized, this T type groove can keep closely isolating with the butterfly plate 2 ' that off-centre is installed during work, thus the leakage rate and the flow of liquid in can strict application valve body 1 '.Being positioned at valve body 1 ' bottom surface that T type groove 3 ' locates to seal and side has relatively high expectations adding man-hour: surface roughness is Ra1.6, and the facial contour degree is 0.05mm.The T type groove 3 ' of this butterfly type valve adds 30 kinds of angles man-hour, specification is from 2inch to 48inch, the lathe tool structure of existing processing T type groove 3 ' comprises the standard cell knife bar, blade, pressing plate and bolt, the groove knife bar is to rectangular shaft with vertically constitute to the rod end head by level, on the rod end head, be processed with open slot, blade is installed in the open slot, the open front end face that pressing plate is against open slot is squeezed in blade in the open slot, pressing plate is fixed together by bolt and groove knife bar, when processing T type groove 3 ', this cutter cuts by filling up different angle block gauges at every turn, this T type groove has 30 kinds of angles, cooperate processing to need 30 kinds of angle block gauges, must be during the different angles of at every turn cutting T type groove 3 ' by detecting to determine by CMM whether angle meets the drawing requirement, and trial cut does not all reach drawing required standard angle many times repeatedly sometimes behind the trial cut.This processing method is also often because pad angle block gauge misoperation causes the angle of T type groove 3 ' suddenly big or suddenly small, bottom land produces and connects tool marks, and surface roughness and facial contour degree all do not satisfy the requirement of drawing, and working (machining) efficiency is extremely low, existing in addition cutter is the nonstandardized technique customization, and cost is very high.

The utility model content

The purpose of this utility model provides a kind of end plane angle T groove cutter, and it has improved machining accuracy and working (machining) efficiency and cutter and has realized standardization, reduces cost greatly.

In order to realize such scheme, technical solution of the present utility model is: a kind of end plane angle T groove cutter, comprise the standard cell knife bar, blade, pressing plate and bolt, described groove knife bar is by the horizontal rectangular bar and is positioned at the rectangular shaft left end and perpendicular to the L shaped bar that vertically constitutes to the rod end head of rectangular shaft, the front end of described rod end head upper surface has an open slot that connects left end, one end of described blade is placed horizontally in the open slot, described pressing plate is against the front of blade, described pressing plate is fixedlyed connected with the groove knife bar by bolt, the upper surface of wherein said rectangular shaft is welded with wedge, before the described wedge, rear end face respectively with described rectangular shaft before, rear end face at grade, the upper surface of described wedge is the oblique inclined-plane of square neck to left down.

After adopting such scheme, the utility model end plane angle T groove cutter is processed as the inclined plane that has angle by the upper surface with the groove knife bar, make an angle corresponding T groove cutter, make cutter realize standardization like this, can produce in enormous quantities, reduce cost, one the corresponding corresponding machining angle of cutter during use, directly machining gets final product, it has overcome different angles in the past and has adopted one cutter correspondence different angles cushion block carried out repeatedly the shortcoming that trial cut and CMM frequently detect processing, thoroughly solve bottom land and connect tool marks, the problem of surface roughness and poor dimensional precision, it has improved machining accuracy and working (machining) efficiency.

The specific embodiment

As shown in Figures 2 and 3, the utility model end plane angle T groove cutter comprises standard cell knife bar 1, blade 2, pressing plate 3 and bolt 4, groove knife bar 1 is the rectangular shaft 11 and the L shaped bar that vertically constitutes to rod end head 12 that is positioned at rectangular shaft 11 left ends by horizontal positioned, the upper surface of rectangular shaft 11 welds the useless knife bar 112 of a wedge shape, during welding the right side and both sides, the front and back installed surface of standard cell knife bar 1 are opened 5 * 45 ° bevel for welding respectively, welding position corresponding with groove knife bar 1 on the useless knife bar 112 is also opened 5 * 45 ° bevel for welding respectively, then the useless knife bar 112 of the standard cell knife bar 1 of bevelling and wedge shape welds, guarantee two knife bars before, the back respectively at grade, align with the right side of rectangular shaft 111 in the right side of the useless knife bar 112 of wedge shape, the upper surface of the useless knife bar 112 of wedge shape be the oblique inclined-plane of square neck to left down, and wedge shape is given up the length of knife bar 112 less than the length of rectangular shaft 111.Rod end head 12 upper surface front ends are processed with the open slot 121 that connects left end, and an end of blade 2 is placed horizontally in the open slot 121, and pressing plate 3 is against the front of blade 2, and pressing plate 3 is fixed together by bolt 4 and groove knife bar 1.

The utility model end plane angle T groove cutter is processed as the inclined plane that has angle by the upper surface with groove knife bar 1, make an angle corresponding T groove cutter, make cutter realize standardization like this, can produce in enormous quantities, reduce cost, one the corresponding corresponding machining angle of cutter during use, directly machining gets final product, it has overcome different angles in the past and has adopted one cutter correspondence different angles cushion block carried out repeatedly the shortcoming that trial cut and CMM frequently detect processing, thoroughly solve bottom land and connect tool marks, the problem of surface roughness and poor dimensional precision, it has improved machining accuracy and working (machining) efficiency.

The above embodiment is described preferred implementation of the present utility model; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that the common engineers and technicians in this area make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
