Technical field
The invention belongs to the technical field of the wide face grinding of cam work, particularly a kind of machinery applied strip lap tool and disc cams working surface is ground.
Background technology
Disc cams is strength member circular motion being changed into the rectilinear motion vertical with its axial direction.The processing of current disc cams adopts three-dimensional vertical knee-type milling machine, Linear cut or boring-milling center to carry out more, its fine finishining also have adopt finger cutter complete curved surface streamline processing, but because still having obvious machining locus in copying, thus the quality of impact motion conversion in engineering reality, directly affects the quality of product.As for the fine finishining using other special grinder bed or numerically control grinder to carry out its working profile, because of high cost, application is restricted.The international and domestic report not yet having the investigation and application it being carried out to the simple machinery equipment of accurately machined structure at present.
Summary of the invention
The object of this invention is to provide close contact and the vertical constant force effect of a kind of lap tool and work piece working profile, by means of the relative sliding kept between work piece working profile and lap tool under close contact state, reach the accurately machined disc cams working profile of working profile to grinding machine.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of disc cams working profile is to grinding machine, it is characterized in that: guiding axle 4 is overlapped upper bearing (metal) 3 and is arranged in bearing block 7, bearing block closed end cap 5 and bearing block 7 are arranged on arbor support 1, arbor support 1 bottom is fixed on base 21, handwheel handle 6 is connected with guiding axle 4 by handwheel 2, cam orientation retaining sleeve 8 is fixed in guiding axle 4 by cam orientation retaining sleeve lock-screw 9, cam orientation retaining sleeve 8 is connected with disc cams 11 by camlock screw 10, lap tool 12 is fixed on lap tool retaining sleeve 14 by lap tool lock-screw 13, the lap tool slide-and-guide post screw 15 be arranged on lap tool retaining sleeve 14 is inserted in the pilot hole of lap tool slide 16 and is slidably connected with lap tool slide 16, lap tool slide 16 is sleeved in guiding axle 4, the stopper slot on base 21 put into by the lap tool slide holding screw 17 be arranged on lap tool slide 16, weight 20 is installed by non-resilient rope 18 and lap tool retaining sleeve counter-jib 22 horizontal symmetrical and is suspended on the both sides of lap tool retaining sleeve 14, the weight limited post 19 be arranged on base 21 is placed in the spacing hole on weight 20, weight 20 and weight limited post 19 are slidably connected in vertical direction.
Beneficial effect of the present invention: by the relative sliding between disc cams working profile and lap tool, in addition weight hangs and ensure that strip lap tool and cam work wide face close contact, vertical direction stress equalization, reaches the object to the grinding of disc cams working profile.Its structure is simple, does not need more power, under the prerequisite ensureing Grinding Quality, reduces processing cost, has saved the energy.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is further described.
A kind of disc cams working profile is to grinding machine, as Fig. 1, shown in Fig. 2 and Fig. 3, one end is guiding axle, screw coordinates disc cams spacing with disc cams clamping device-spacing collar, the other end is that guiding axle matches with strip lap tool clamping device-lap tool slide, the axis of the axis of disc cams and strip lap tool is parallel to each other, strip lap tool is made to contact closely with disc cams working profile with suspension weight, vertical direction producing balanced forces, when handwheel band action-oriented axle rotates, disc cams starts to rotate, and lap tool does not turn, then disc cams working profile and lap tool produce relative sliding, in addition weight hangs and ensure that strip lap tool and cam work wide face close contact, vertical direction stress equalization, strip lap tool is driven to make periodically rectilinear motion with the curvilinear motion of working profile, realize keeping between the wide face of strip lap tool and cam work the relative motion under close contact state, and then reach the object of grinding.Its concrete structure is:
Guiding axle 4 is overlapped upper bearing (metal) 3 and is arranged in bearing block 7, locate with bearing block closed end cap 5 pairs of bearings 3, bearing block closed end cap 5 is arranged on arbor support 1 together with bearing block 7, arbor support 1 bottom is fixed on base 21, and base 21 is supported and position-limiting action guiding axle 4 together with bearing block 7 by arbor support 1, bearing block closed end cap 5, bearing 3.Handwheel handle 6 is connected with guiding axle 4 by handwheel 2, cam orientation retaining sleeve 8 is fixed in guiding axle 4 by cam orientation retaining sleeve lock-screw 9, cam orientation retaining sleeve 8 is connected with disc cams 11 by camlock screw 10, power is by handwheel handle 6, handwheel 2, guiding axle 4 and cam orientation retaining sleeve 8 pass to disc cams 11, disc cams 11 is rotated around guiding axle 4 axis, simultaneously, by cam orientation retaining sleeve lock-screw 9, cam orientation retaining sleeve 8 is fixed in guiding axle 4, cam orientation retaining sleeve 8 and camlock screw 10 pairs of disc camses 11 spacing and fixations, form cam clamping device overall.Lap tool 12 is fixed on lap tool retaining sleeve 14 by lap tool lock-screw 13, the lap tool slide-and-guide post screw 15 be arranged on lap tool retaining sleeve 14 is inserted in the pilot hole of lap tool slide 16 and is slidably connected with lap tool slide 16, coordinated with at lap tool slide 16 pilot hole by lap tool slide-and-guide post screw 15, make lap tool 12 make vertical linear motion along the axis direction of slide-and-guide post screw 15.Be sleeved in guiding axle 4 by lap tool slide 16, coordinate with the stopper slot on base 21 by means of the lap tool slide holding screw 17 be arranged on lap tool slide 16, form fixing spacing relation, lap tool clamping device entirety is not moved horizontally at work.Weight 20 is installed by non-resilient rope 18 and lap tool retaining sleeve counter-jib 22 horizontal symmetrical and is suspended on the both sides of lap tool retaining sleeve 14, makes lap tool 12 be subject to vertical tension, ensures lap tool 12 and disc cams 11 working profile close contact.The weight limited post 19 be arranged on base 21 is placed in the spacing hole on weight 20, weight 20 and weight limited post 19 are slidably connected in vertical direction, coordinated with the spacing hole on weight 20 by weight limited post 19, prevent weight 20 from swinging and producing the component on other direction.
