The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the invention, the technical scheme in the embodiment of the invention is clearly and completely described.
The invention provides a kind of excavator swing arm processing tool, as shown in Figure 3, comprise pedestal 1, be provided with middle supporting positioning seat 5, rear leaning seat 6, front side board retaining mechanism 2, latus inframedium retaining mechanism 3, back side panel retaining mechanism 4 on the described pedestal 1, and auxiliary retaining mechanism 7.
Described middle supporting positioning seat 5 is located at bending plate bending below in the swing arm, be U-shaped, its opening both sides end face is for before mating respectively described interior bending plate bending, the arc supporting face 501 of back segment shape, its U-shaped bottom is provided with axis hole 502 and cover is through on the vertical shaft 8, the lower end of described vertical shaft 8 is fixedly connected with described pedestal 1, the axle body of described vertical shaft 8 is provided with screw thread, and be connected with clamp nut 9 in the below of described middle supporting positioning seat 5, in this, can support described middle supporting positioning seat 5 by clamp nut 9, after when clamping, finely tuning up and down, supporting positioning seat 5 in can locating by this clamp nut 9.
Described rear leaning seat 6 is located at assembly assembly tail side behind the described swing arm, and described rear leaning seat 6 is comprised of the positioning base that is fixedly connected with described pedestal 1 and vertical support, and in this, described rear leaning seat 6 adds in feed and plays a part man-hour against supporting.
Outside lateral plate locking mechanism 2,3,4 lays respectively at before, during and after the swing arm biside plate before, during and after described.Particularly it is symmetrically arranged with front side board retaining mechanism 2 outside front portion of swing arm biside plate, and its outside, middle part is symmetrically arranged with latus inframedium retaining mechanism 3, and its rear outside is symmetrically arranged with back side panel retaining mechanism 4; Lateral plate locking mechanism 2,3,4 is comprised of vertical several screw rods 89 of being located at the hold-down support 88 on the described pedestal 1 and being located on the described hold-down support 88 respectively before, during and after described.In the present embodiment, described hold-down support 88 is parallel to the swing arm side plate and is symmetrically distributed in twos swing arm side plate both sides, wherein, described forward and backward lateral plate locking mechanism 2,4 the hold-down support 88 plate body shape that is rectangle, the hold-down support 88 of described latus inframedium retaining mechanism 3 is inverted u-shaped, two avris of each hold-down support 88 have all extended upper lug 881 and lower lug 882, on each described lug screw rod 89 are installed all.In this, the screw rod 89 of installing on upper lug 881 and the lower lug 882 can lock when swing arm is positioned on the frock varying level position.And the hold-down support 88 on the latus inframedium retaining mechanism 3 is set to inverted u-shaped, the clamp nut 9 on the described vertical shaft 8 of being convenient to advance and retreat from the outside, handled easily.
Each described hold-down support 88 inboard also slidely connects auxiliary retaining mechanism 7 by the slide construction of vertical setting; In present embodiment, described auxiliary retaining mechanism 7 is comprised of support plate 701 and the fastening stud 702 of being located on the described support plate 701.Simultaneously, in present embodiment, described hold-down support vertically is provided with slide rail 10 on 88 inboards, the slide block 11 that described support plate 701 outsides are provided with, and slide rail 10 and slide block 11 Corresponding matchings consist of described slide construction.Linear electric motors are connected with described support plate 701.In this, be respectively equipped with a slide rail 10 on each described forward and backward lateral plate locking mechanism 2,4 the hold-down support 88, be connected with respectively an auxiliary retaining mechanism 7; And the hold-down support 88 of latus inframedium retaining mechanism 3 is inverted u-shaped, symmetrical two slide rails 10 on it, thus being connected with respectively two auxiliary retaining mechanisms 7, structure is more reliable and more stable when location, clamping thus.
Described middle supporting positioning seat 5 is fixedly connected with described auxiliary retaining mechanism 7 with described latus inframedium retaining mechanism 3 inboards, namely in supporting positioning seat 5 lower ends be fixedly connected with the support plate 701 of described auxiliary retaining mechanism 7.Thus, behind the fastening stud 702 locking swing arms on the auxiliary retaining mechanism 7, driven by linear electric motors, when slide block 11 slides up and down along slide rail 10, the swing arm of middle supporting positioning seat 5 and upper support thereof is subjected to displacement together, with this horizontal level of adjusting swing arm, satisfies the range of work of lathe, and under the guide effect of the slide rail 10 of vertical setting, can guarantee four parallel to each other and left-right symmetry of hinge hole that process.
During clamping, swing arm is supported on the described middle supporting positioning seat 5, after the hinge hole contraposition and linear electric motors driving adjustment swing arm horizontal level with swing arm, clamp nut 9 on locking vertical shaft 8 axle bodies and the fastening stud 702 on the auxiliary retaining mechanism 7, detect the depth of parallelism of each hinge hole, if not parallel or inclination is arranged, again adjust and definite range of work after, can process behind the screw rod 89 on the lateral plate locking mechanism 2,3,4 before, during and after the locking respectively.So when processing swing arm on the less lathe of the range of work, can unclamp/tightly lock screw rod 89, driven up and down by linear electric motors and adjust, namely when linear electric motors driving adjustment makes swing arm be positioned at horizontal level minimum on the frock, can process the top of swing arm; When driving to adjust, linear electric motors make swing arm be positioned at horizontal level the highest on the frock, with the bottom of processing swing arm.
In sum, the present invention by middle supporting positioning seat 5 in below general support swing arm, leaning seat 6 comes against supporting in the tail side later on, and by after assisting retaining mechanism 7 to come auxiliary clamp, under the slide construction guide effect that vertically arranges, driven the horizontal level that gets off to adjust swing arm by linear electric motors, simultaneously, by before, during and after lateral plate locking mechanism 2,3,4 lock, realizing having realized adjusting up and down the horizontal level of swing arm on the reliable basis of positioning and clamping, can adapt to the little lathe of the range of work, so that it is good to have applicability, and the advantage of saving cost.
To the above-mentioned explanation of the disclosed embodiments, make this area professional and technical personnel can realize or use the present invention.Multiple modification to these embodiment will be apparent concerning those skilled in the art, and General Principle as defined herein can in the situation that does not break away from the spirit or scope of the present invention, realize in other embodiments.Therefore, the present invention will can not be restricted to these embodiment shown in this article, but will meet the widest scope consistent with principle disclosed herein and features of novelty.
