Abstract
The invention provides a kind of with the super hard abrasive instrument after Overheating Treatment, having certain material hardness, the internal splined hole key side that deforms and lose precision is by interior centering requirement, to buffet the honing grinding machine that the honing principle is carried out the technology of honing shaping and used this technology development.Evidence, the internal spline after shaping meets the national standard of GB1144-87 disc flower key connecting decided at the higher level but not officially announced fully.Its productivity ratio is 15～20 times of domestic and international special-purpose splined hole grinding technique.
Description
The present invention relates to plover mill machine or device.
The invention provides a kind of employing and be coated with the grinding equipment of the instrument of super hard abrasive (diamond or cubic boron nitride) by the internal spline key side of interior centering principle, buffeting honing mechanism high accuracy, high efficiency processing generation distortion after heat treatment is hardened, forfeiture precision.
At present this technical field be adopt super hard abrasive emery wheel under the high speed rotation status, carry out grinding by interior centering principle.The vertical rectangular spline key side grinding bed of the horizontal internal spline key side grinding bed that West Germany produces and China's development is to utilize outside diameter to stretch in the splined hole less than the emery wheel that is coated with the CBN abrasive material of workpiece splined hole, utilize abrasive wheel end face to carry out grinding, ground a keyway and divided once degree, till whole key side grindings are intact.Another kind is to adopt the broaching tool that is coated with super hard abrasive to realize the processing of internal spline key side.These methods all exist the low shortcoming of working (machining) efficiency.
The objective of the invention is in order to solve a kind of instrument that is coated with super hard abrasive, the internal spline key side that deforms, loses precision behind heat-treatment quenching by interior centering principle, is carried out the device that shaping is processed to buffet honing mechanism.
Technical solution of the present invention is: have a lathe bed, a workbench that places the column at lathe bed rear portion and place the anterior holding workpieces of lathe bed and indexing mechanism and testing agency, one is equipped with the planker (5) of buffeting system and super hard abrasive instrument and the planker (7) that is connected with column, it is characterized in that: planker (7) is rolled with column by accurate guiding mechanism and is connected.Planker (7) is driven by ball screw (14) by oil cylinder or numerical control stepper motor (2) and does vertical feed campaign, and planker (5) is connected, buffets that device (3) is connected with the instrument that is coated with super hard abrasive (12) with coupling (6) by planker (5) and drive instrument (12) is done the vibration of the big amplitude of high frequency by accurate guiding mechanism and planker (7) rolling.
Placing turn device (1) on the workbench of lathe bed front portion to promote precision positioning cover (9) by the processing technology requirement drives workpiece and do accurate, quantitative deflection.Amount of deflection can be aligned in advance, and by placing the checkout gear (4) on the workbench to carry out Clinical detection.Place precision positioning cover (9) and clamping device (8) on the workbench to make workpiece accurately location and clamping.
Adopt disc flower keyhole key side decided at the higher level but not officially announced honing in 1～2 minute, to repair completion of processing to the internal spline key side more than one six key, and the internal spline key side of existing one six key of producing of the every finishing of grinding machine needs 30～45 minutes, evidence, the internal spline after shaping meet the national standard that GB1144-87 disc flower key decided at the higher level but not officially announced connects fully.Its productivity ratio is 15～20 times of domestic and international grinding technique.
Concrete structure of the present invention is provided by following examples and accompanying drawing.
Fig. 1 is a mounting structure schematic diagram of the present invention.
Fig. 2 is the A-A profile of Fig. 1.
Fig. 3 is the vertical view of Fig. 1.
Fig. 4～Fig. 7 is the shaping processing work sheet that is coated with the super hard abrasive instrument.
The structure of this device comprises: lathe bed 11, column 10 places the lathe bed rear portion, numerical control stepper motor 2 and ball screw 14 are installed on it, and planker 7 is connected with column 10 by accurate guiding mechanism, and does the vertical direction feed motion by numerical control stepper motor 2 by ball screw 14 driving plankers 7.Upper slide rest 5 of planker 7 positive installations is connected by accurate guiding mechanism between the two, and axially bored line and tool axis are in full accord in X, Y, Z direction in the precision positioning cover 9 assurance splines.Be equipped with on the planker 5 and buffet device 3 and the instrument 12 that is coated with super hard abrasive is installed, buffet device 3 drive instruments 12 and make the big amplitude dither of high frequency by coupling 6.
Place on the workbench of lathe bed front portion turn device 1 is housed, drive precision positioning cover 9 by turn device 1 and do accurate, quantitative deflection by technological requirement.Amount of deflection can be pressed the technological requirement adjustment in advance, and by checkout gear 4 Clinical detection, places precision positioning cover 9 on the workbench and clamping device 8 and checkout gear 4 to make accurately location and clamping of workpiece.Checkout gear 4 is realized the Clinical detection of amount of deflection.
After workpiece is installed clamping by precision positioning, by the PC device sender of finishing operation sequence in advance, numerical control stepper motor 2 is carried out, make planker 7 do vertical feed by ball screw 14 with the speed of setting up in advance, make the super hard abrasive instrument 12 that is coated with that is loaded on the planker 5 by coupling 6 enter the processing district, at this moment buffet device 3 and do the big amplitude vibration of high frequency by PC control drive planker 5, its vibration frequency and amplitude can be done stepless adjustment by the processing technology requirement in prescribed limit.PC carries out by the program sender control turn device 1 of preliminary election simultaneously, by precision positioning cover 9 workpiece is done along reverse accurate quantification deflection, thereby realize workpiece 13 is done honing processing, after being worked into given size, the PC device sets back each parts, machine-tool quits work, and refills workpiece and enters next fabrication cycles, carries out honing processing so again and again.
