The method of using clamp body to carry out the machining of hydraulic crawler excavator walker main body is divided into following 4 steps:
Step 1: will not place the clamp body that to move crossbeam and place on the platen, and cooperate the location, and make clamp body parallel with platen X axle with the T type groove of platen;
Step 2: the walker main body is hung to clamp body, make lower plane and the clamp body left side V-block of pivoting support seat connecting plate, the locating surface snap of right V-block; The adjustment first adjustment depression bar, the second adjustment depression bar make the side of walker main body lower cover parallel with platen X axle;
Step 3: can move crossbeam and be placed on first bearing and second bearing and lock second depression bar, and lock first depression bar simultaneously;
Step 4: require the walker main body is carried out machining according to art work sheet.
The machining process of a kind of hydraulic crawler excavator walker main body provided by the invention is through special clamp body, and the lower plane of choosing pivoting support seat connecting plate is that machine adds benchmark, can guarantee the even and flatness requirement of pivoting support seat connecting plate thickness.Clamp body left side V-block can slide, walker main body that can the clamping different type of machines.
The machining process of a kind of hydraulic crawler excavator walker main body provided by the invention has overcome the deficiency of prior art; Can guarantee that walker main body machine adds size, form and position tolerance and complete machine performance, highly versatile, operating procedure is simple; Improve working (machining) efficiency, reduced the excavator manufacturing cost simultaneously.

The specific embodiment
For making the present invention more obviously understandable, now with a preferred embodiment, and conjunction with figs. elaborates as follows.
A kind of machining process of hydraulic crawler excavator walker main body uses clamp body, and in conjunction with Fig. 4～Fig. 6, clamp body is divided into left and right sides two parts.Left-hand component: four hangers 8 are arranged, convenient lifting on the left bottom plate 10; Be fixed with two line slide rails 17 on the left bottom plate 10, sliding support 6 is contained on the line slide rail 17 through seat sliding 18, and sliding support 6 connects together with left V-block 11.Left side V-block 11 promotes and can horizontally slip along line slide rail 17 through manual work.Article two, the outside of line slide rail 17 is equipped with first bearing 9 and second bearing 15 respectively.During clamping, can move 5 on crossbeam on first bearing 9 and second bearing 15, and second depression bar 14 of screwing affacts on sliding support 6 and the left V-block 11 and reaches the purpose that compresses through moving.When workpiece processing centering, adjust the circumferential position that depression bar 19 can be finely tuned work piece walker main body through rotating second on adjustment depression bar 16 of first on the 3rd bearing 20 or the 4th bearing 21.
Right-hand component: four hangers 8 are arranged on the right base plate 13, be fixed with right support 22 above the right base plate 13, right support 22 connects right V-block 12.The clamping of vertical direction is to reach the purpose that compresses through 4 first depression bars 7 on screw left V-block 11, the right V-block 12.
The method of using clamp body to carry out the machining of hydraulic crawler excavator walker main body is divided into following 4 steps:
Step 1: catch on hanger 8 with suspender; Left-hand component and the right-hand component of not placing the clamp body that can move crossbeam 5 are successively hung to platen; Clamp body leans on positioning key 4 to cooperate the location with the T type groove of numerical control gantry machining center platen, makes clamp body parallel with platen X axle.
Step 2: the walker main body is hung to clamp body, make lower plane and the clamp body left side V-block 11 of pivoting support seat connecting plate 1, the locating surface snap of right V-block 12; The adjustment first adjustment depression bar 16, second is adjusted depression bar 19 makes the side of walker main body lower cover 3 parallel with platen X axle.
Step 3: can move crossbeam 5 and be placed on first bearing 9 and second bearing 15 and lock second depression bar 14, and lock first depression bar 7 simultaneously.
Step 4: require the walker main body is carried out machining according to art work sheet.
Check form and position tolerance after the machining; The flatness A=0.15 on plane and thickness
are implemented the flatness A=0.1 on plane on the pivoting support seat connecting plate 1 of this processing method processing back on the drawing requirement pivoting support seat connecting plate 1; Thickness
meets drawing requirement, has solved traditional mechanical processing technique method size and the overproof problem of form and position tolerance.
The machining process of a kind of hydraulic crawler excavator walker main body provided by the invention can not only guarantee that the flatness and the thickness of pivoting support seat connecting plate 1 is even, and can satisfy the process conditions of the walker main body production in enormous quantities of general different type of machines.
