The specific embodiment

Describe the preferred embodiment that paperback is put that mills of the utility model in detail below in conjunction with accompanying drawing.

Shown in Fig. 1-4, it shows according to the paperback of milling of the utility model and puts 100.Milling paperback puts 100 and comprises base 10, fixture 20, guide rail 30, support 40, depthkeeping grip assembly 50 and milling cutter 60.Base 10 the place aheads are provided with platform 11, are used for placing treating miller part 70; Fixture 20 is used for treating that miller part 70 remains on platform 11; Guide rail 30 is fixed on the base 10; Support 40 is slidably mounted on the guide rail 30; Depthkeeping grip assembly 50 is installed on the support 40, and is positioned at the top of platform 11; Milling cutter 60 is installed on the depthkeeping grip assembly 50, is used to mill the flat miller part 70 of treating.

Fixture 20 comprises two L shaped pressing plates 21, is placed on respectively on the both sides of platform 11.L shaped pressing plate 21 has horizontal component and vertical component, and wherein vertical component is used to push and treats that miller part 70, horizontal component are used for fixing on the base 10 in the groove that is provided with.The horizontal component of L shaped pressing plate 21 is provided with a

long slot bore

22, and 22 one-tenth of this long slot bores stepped (seeing shown in Fig. 3), screw 23 pass long slot bore 22 L shaped pressing plate 21 is fixed in the groove 12 on the base 10.The head of screw 23 is positioned at the larger-size part of long slot bore, and its threaded portion is positioned at the less part of size, and tightens in the groove 12.In addition, fixture 20 also comprises nut 24 and screw rod 25, and screw rod 25 passes the hole 26 on the L shaped pressing plate, tightens screw rod 25 through nut 24, is used for compressing L shaped pressing plate 21 and adjusting its level when treating miller part 70 compressing.According to the position of rivet on the workpiece, can adjust the relative position of screw 23 and long slot bore 22, thereby rivet portion is exposed in the position of the L shaped pressing plate 21 in adjustment both sides.Another or the 3rd L shaped pressing plate 21 ' also can be set, and it is positioned at platform central authorities, and the structure of L shaped pressing plate 21 ' and L shaped pressing plate 21 are roughly the same, and just size is less, and has saved nut and screw rod.L shaped pressing plate 21 ' can play the auxiliary effect of treating miller part 70 of pushing.

Guide rail 30 is installed on the upper surface of base 10 through screw etc.Support 40 is slidably mounted on the guide rail 30.The place ahead of support 40 is provided with hole 41, is used for accommodating depthkeeping grip assembly 50.Behind the height of adjusting depthkeeping grip assembly 50, be fixed on through locknut in the hole 41 of support 40.Support 40 downsides are provided with guide rail slide block 42, cooperate with guide rail 30 to form guideway.Guide rail slide block 42 is provided with dovetail groove, and guide rail 30 is provided with the projection that is slidingly matched with dovetail groove, thereby support 40 can slide along guide rail 30.

Depthkeeping grip assembly 50 comprises axle 51, rolling bearing 52, outer sleeve 53, upper bush 54 and lower sleeve 55, spring 56, bottom 57 etc.The below of axle 51 is provided with screwed hole 511, and milling cutter 60 passes and is tightened in the screwed hole 511 from depthkeeping cover bottom 57.Can connect the pneumatic tool (not shown) on the axle 51 and come driving shaft 51 to rotate, mill flat thereby drive milling cutter 60 rotations.During use, pneumatic tool can be pressed axle 51 and driving shaft rotation, so during the position of adjustment milling cutter 60; Axle 51 is pressed, upwards promoted upper bush 54 compression springs 56, upwards tighten lower sleeve 55 then; When the lower surface of adjusting to milling cutter 60 just flushes with the lower surface of depthkeeping cover bottom 57, unclamp upper bush 54, upper bush 54 moves down under the effect of spring 56; Tooth up to upper bush 54 belows is meshed with the tooth of lower sleeve 55 tops, thereby prevents that lower sleeve 55 from rotating.

Mill paperback and put 100 and also comprise positioning element 80, this positioning element 80 is fixed on the sidewall 13 with platform 11 perpendicular abutment.Among the embodiment shown in the figure, positioning element 80 comprises left and right alignment pin, through its extension elongation of screw thread control.Machine adds edge strip and is divided into left and right, and wallboard is curved surface, utilizes base groove to carry out Primary Location, when looking part again and being left part or right part, locatees with different alignment pins.

Milling cutter 60 also is special cutter, adopts the welded type carbide alloy to mill flat cutter, and carbide chip is carried out the angle reconditioning, prevents to mill scratch side wall panel at ordinary times.

This it is known to the person skilled in the art that the depthkeeping cover is a kind of instrument that leans on screw thread control milling cutter outreach.But common depthkeeping cover can't be put into so narrow and small position, thereby need change a social system the depthkeeping cover, enlarges its base diameter, and covering need be milled flat rivet position.But the enlarged-diameter of depthkeeping cover can cause the center line of depthkeeping cover to be positioned at outside the base, firmly presses down to cause easily to mill flat instrument and part turns up; Therefore designing support fixes the flat instrument that mills; Adopt telescopic clamping, regulate the position after, lock with holding screw.

Need mill flat rivet not point-blank though machine adds edge strip, it is little to differ the position, is milling at ordinary times; Because mill flat cutter enlarged diameter, can look after all rivet hole positions, so select for use guideway to fix support; Can horizontally slip, not need to carry out again repetitive operations such as dismounting.Owing to mill at ordinary times, the vibration of generation is bigger, and the bottom wallboard is damaged in order to prevent; Do not allow to adopt pressing plate to press-fit, slot so be employed on the base, the installation pressing plate adds edge strip to machine and press-fits; When not needing pressing plate; Can unclamp soket head cap screw, pressing plate is removed, avoid repetition dismounting and part to lose.

The case of practical implementation described in the utility model is merely the preferable case study on implementation of the utility model, is not the practical range that is used for limiting the utility model.Be that all equivalences of doing according to the content of the utility model claim change and modification, all belong to the protection domain of the utility model.
