Description

Wedge processing tool

Technical field

The utility model relates to field of machining, is specially a kind of frock for wedge processing.

Background technology

In mould and machining, inclined-plane is installed surface especially tiltedly, owing to there is barb negative angle, directly adopts common three axle machine toolings very difficult (as Fig. 1).Referring to Fig. 2, conventionally, in order to process the wedge 3 of barb negative angle, need to first process the special tooling accessory 4 of corresponding angle, could meet the processing of cutter 5, the needed frock of wedge of different angles is different, has therefore caused huge waste.

CN201329501 discloses a kind of wedge processing device, and it comprises base and the flap hinged with base, and when use, the rotational angle of adjusting as required flap also supports with corresponding back-up block.Although this processing unit (plant) has been realized the needs of wedge processing, the operation inconvenience of this device, for different workpiece, still needs different back-up blocks, and versatility is not high.

Summary of the invention

The purpose of this utility model is to provide a kind of wedge processing tool, and it is simple to operate, versatility is high, is applicable to multiple wedge processing.

Wedge processing tool described in the utility model, comprise holder and turntable, described holder is provided with indent arc sections, on described turntable, be provided with workpiece installed surface, the bottom of described turntable is the arc surface coordinating with the indent arc sections of described holder, and turntable is by the rotating indent arc sections that is assemblied in described holder of described arc surface; The axial two ends of indent arc sections at described holder are respectively equipped with a baffle plate, the medial surface of described baffle plate props up respectively the axial both ends of the surface of described turntable, on the arc surface of described turntable, be circumferentially distributed with multiple indexing troughs, on described holder, be provided with lock piece, it can insert in corresponding indexing trough.

Further, described lock piece is tabular component, and it is located on described holder by a screw.

Further, described workpiece installed surface is parallel to the axis of the arc surface of turntable bottom, on described workpiece installed surface, offers T-shaped groove.

Further, be provided with and the deep-slotted chip breaker of its arc surface coaxial line in the both ends of the surface of described turntable, on the medial surface of described baffle plate, be provided with alignment pin, described alignment pin is inserted in the deep-slotted chip breaker of described turntable.

Further, be all circumferentially distributed with indexing trough at the axial two ends of the arc surface of described turntable, be also respectively provided with two lock pieces at the axial two ends of described holder, two lock pieces of described every one end are located at respectively the both sides at the top of described indent arc sections.

Further, the relative holder of described turntable often turns over an indexing trough, and its rotational angle is 5 °.

Further, the thickness of described tabular lock piece and the width of described indexing trough are consistent.

Wedge processing tool described in the utility model is simple to operate, reliable in function, versatility are high, only need adjust according to the requirement of different workpieces the rotational angle of the relative holder of turntable, can change workpiece angle, has met the processing request of common three axle lathes.Can realize the processing of most wedges by this frock, avoid for different angles wedge and the problem of specialized designs frock greatly reduces processing cost.

The specific embodiment

Below in conjunction with drawings and Examples, the utility model is described in further detail:

Wedge processing tool as shown in Figure 3, comprise holder 1 and turntable 2, described holder is provided with indent arc sections 11, the bottom of described turntable is the arc surface 22 coordinating with the indent arc sections 11 of described holder, and turntable 2 is by the rotating indent arc sections 11 that is assemblied in described holder 1 of described arc surface 22.

Referring to Fig. 5, on described turntable 2, be provided with workpiece installed surface 21, described workpiece installed surface 21 is parallel to the axis of the arc surface 22 of turntable bottom, offers T-shaped groove 24 on described workpiece installed surface, and wedge 3 to be processed is fixed on described T-shaped groove 24.

Referring to Fig. 4, be separately installed with a baffle plate 12 at the axial two ends of indent arc sections 11 of described holder 1 by bolt, the medial surface of described baffle plate props up respectively the axial both ends of the surface of described turntable, to limit the axial location of turntable 2.In the both ends of the surface of described turntable 2, be provided with the deep-slotted chip breaker 25 with its arc surface coaxial line, on the medial surface of described baffle plate 12, be provided with alignment pin 14, described alignment pin 14 is inserted in the deep-slotted chip breaker 25 of described turntable, described alignment pin coordinates with deep-slotted chip breaker, meeting under the prerequisite that turntable can rotate on holder, can guarantee that both can not throw off.

On the arc surface 22 of described turntable 2, be circumferentially distributed with multiple indexing troughs 23, on described holder 1, be provided with the lock piece 13 coordinating with described indexing trough, described lock piece 13 is tabular component, it is located on described holder 1 by a screw, when described lock piece 13 inserts after corresponding indexing trough 23, screwing this screw can lock lock piece 13.For improving the efficiency of assembling of workpiece, while opening this lock piece 13, the general screw that only needs opposite direction to outward winding a little on it, can outwards rotate lock piece and throws off indexing trough completely, does not need lock piece 13 whole unloading from holder 1.

Because the circumferential rotation of turntable 2 is to limit by described lock piece 13, therefore 2 can not become flexible for guaranteeing to add man-hour turntable, the thickness of described tabular lock piece 13 is consistent with the width of described indexing trough 23.

Wedge 3 length of the normal processing of cause are longer, generally can reach 1-2m, for guaranteeing holder 1, the reliable of turntable 2 fixed, axial two ends at the arc surface of described turntable are all circumferentially distributed with indexing trough 23, axial two ends at described holder 1 are also respectively provided with two lock pieces 13, and two lock pieces 13 of described every one end are located at respectively the both sides at the top of described indent arc sections.Four lock pieces are set altogether on described holder, lock respectively four angles of turntable.

The angle of considering wedge 3 ramps mostly is 5 multiple, therefore the minimum calibration of described turntable is made as to 5 °, and the relative holder of described turntable often turns over an indexing trough 23, and its rotational angle is 5 °.

Above-mentioned frock in use, the datum level of wedge 3 is fixed on the workpiece installed surface 21 of described turntable, then according to be processed of the wedge angle with datum level, rotates described turntable 2 to required angle, facilitate common three axle machine toolings, for example, make face to be processed be level or vertical.Then rotate four lock pieces 13 on holder 1, it is all inserted in corresponding indexing trough 23, and tighten the screw on lock piece, just completed the assembling of above-mentioned frock and workpiece.

Above-mentioned example is only explanation technical conceive of the present utility model and feature, and its object is to allow industry technical staff understand content of the present utility model and implement according to this, can not limit protection domain of the present utility model with this.All equivalent transformations doing according to the utility model Spirit Essence or modification, within all should being encompassed in protection domain of the present utility model.
