The specific embodiment
Be applied to a specific embodiment of washing machine pallet Milling Process as shown in Figure 1 and Figure 2 for the utility model.Pallet positioning clamping device in the present embodiment comprises a body 1 and is arranged on the location of one on the body 1 clamping device 2.Body 1 comprises a upper substrate 11, an infrabasal plate 12, two substrates by a plurality of support vertical shafts 13 between the upper and lower every setting.
Positioning clamping device 2 comprises that a main positioner 21 and is fixedly installed on the tight cylinder 22 of main folder on the infrabasal plate 12, also comprises the main hold down gag 23 with tight cylinder 22 interlocks of main folder.Main positioner 21 comprises that being fixedly installed on one on the infrabasal plate 12 by a plurality of location vertical shaft 211 locatees substrate 212, be set with a main keeper 213 on the substrate 212 of location, main keeper 213 is the horizontal location benchmark of workpiece 5 with the contact surface of location substrate 212.Main hold down gag 23 compresses connecting rod 231 by one and is aided with a compacting ring 232 and forms interlock with the tight cylinder 22 of main folder.
Special feature of the present utility model is that the pallet positioning clamping device also comprises a specially designed multiple spot auxiliary support apparatus.According to the needs of the different strong points in each specific embodiment, this multiple spot auxiliary support apparatus can be changed to 3 auxiliary support apparatus that principle is identical, structure similarly has three strong points or have 4 multiple variations such as auxiliary support apparatus of four strong points.In this specific embodiment, the needs according to 15 Milling Process points of washing machine pallet are provided with one group of 3 auxiliary support apparatus, three groups of 4 auxiliary support apparatus.
Figure 3 shows that among Fig. 2 along A to, 3 auxiliary support apparatus partial schematic sectional view.Figure 4 shows that among Fig. 2 along B to, 4 auxiliary support apparatus partial schematic sectional view.Both principles are identical, and structure is similar.Multiple spot auxiliary support apparatus 3 comprises that (nail is 3 to a plurality of the nails 32 that are arranged on the supplemental support cylinder 31 on the infrabasal plate 12 and lead by upper substrate 11 in 3 auxiliary support apparatus, a nail is 4 in 4 auxiliary support apparatus), a plurality of nails 32 are arranged on the supplemental support cylinder 31 by linkage 33.Linkage 33 comprises one-level connecting rod 331, one-level support column 332 and is arranged on secondary connecting rod 333 on the one-level support column 332 that a plurality of nails 32 are arranged on the secondary connecting rod 333.
For cooperating the support power of above-mentioned four groups of multiple spot auxiliary support apparatus 3, with each auxiliary support apparatus 3 corresponding position on also be respectively arranged with auxiliary clamping device 4.The structure of four groups of auxiliary clamping devices 4 identical (only illustrating one group among Fig. 1) comprises an auxiliary auxiliary pressing plate 43 that compresses cylinder 41 and be rotatably connected by auxiliary connecting rod mechanism 42 that is fixedly installed on upper substrate 11 downsides respectively.Auxiliary connecting rod mechanism 42 is a sliding pin structure, comprises being fixed on auxiliary compressing sliding pin 422 on 41 in the cylinder, being fixed on and compressing supporting seat 421 and fulcrum 423 on the upper substrate 11.
Also be set with a spline part 14 on the upper substrate 11, spline part 14 is a spline alignment pin.
The utility model is by relay, delay circuit control automatic sequence clamping process, and controls and adjust each thrust and support force by air pressure regulator.
The course of work of the present utility model is as follows: workpiece 5 is put into main keeper 213 on the main body 1, and be close to after firmly believing the position of spline part 14 relative workpiece 5, put into compacting ring 232 again, start button.The at first tight cylinder of main folder 22 work, cylinder axis moves down, and drives that to compress connecting rod 231 downward, and the draw that compacting ring 232 pressurizeds are close to bar 231 applies main clamping force to workpiece 5.This moment workpiece 5 datum level near the locating surface of clamping device, the central shaft of the centrally aligned master keeper 213 of workpiece 5, rotation direction is spacing by spline part 14.
Under the control of delay circuit, supplemental support cylinder 31 is started working afterwards.The cylinder axis of supplemental support cylinder 31 moves up and produces top power, jack-up one-level connecting rod 331, by one-level support column 332 roof pressure power is passed to secondary connecting rod 333 again, because the installation site of each nail 32 is the positions, hole by regulation on the upper substrate 11 on the secondary connecting rod 333, so each nail 32 can only move up and down, roof pressure power effect lower support nail 333 at secondary connecting rod 333 can be adjusted the actual height that moves up automatically, and is adjacent to mutually with the supporting surface of workpiece 5.One group of 3 auxiliary support apparatus and three groups of 4 auxiliary support apparatus have the periphery that 15 strong points act on workpiece 5.
Last auxiliary clamping device 4 work.After each support force put in place, auxiliary clamping cylinder 41 was started working.The cylinder axis of auxiliary clamping cylinder 41 moves up, and drives auxiliary connecting rod mechanism 42 upwards, under the effect that compresses supporting seat 421, and the periphery of auxiliary pressing plate 43 downward workpiece pressings 5.At this moment, workpiece 5 has realized being in fully stable state to be processed, and numerical control is milled and can be milled pin processing to workpiece 5.
After process is finished, only need press stop button, each cylinder acting in opposition, each clamping force and support force on the workpiece 5 withdraw from succession, and positioning clamping device restPoses.
The utility model is owing to adopted said structure, behind the work piece feeder, part to be processed center and axial height have been determined in main location, treat that reinforcing compresses after, the multiple spot supplemental support of periphery can be automatically enter the positioning supports point in succession with the nature of part to be processed.Then, can produce a clamping force in succession in the reaction direction of these strong points, stablize with the axial dimension of controlling peripheral a plurality of processing stands errorless, to satisfy the final size stability of Milling Process.
In sum, described in this specification is several preferred embodiment of the present utility model, and above embodiment is only unrestricted in order to the explanation the technical solution of the utility model.All technical staff in the art comply with design of the present utility model on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should be within claim protection domain of the present utility model.
