Abstract
The invention provides a mechanical processing method for hydraulic excavator bucket rod U-shaped plate grooves, which is characterized by comprising the following steps of: firstly, installing a cushion block and a locating pin on a workbench, hoisting two U-shaped plates to the workbench through a permanent magnetic chuck, moving the U-shaped plates to be adjoined with the locating pin, and after confirming that the two U-shaped plates are completely coincided, locking a pressing plate to be located; and secondly, using a 45-degree chamfer mill of a vertical machining centre to sequentially mill each groove on each circular arc part on the U-shaped plates except for the grooves with the front ends being close to a central line, wherein the rotating speed of a main shaft is 650-900r/min, and the feed rate is 250-450mm/r. The invention provides the mechanical processing method for hydraulic excavator bucket rod U-shaped plate grooves, which overcomes the defects in prior art, is beneficial to the improvement of the quality of the production efficiency of the grooves of the U-shaped plates, is simple and safe to operate, and has strong generality.
Description
Technical field
The present invention relates to a kind of hydraulic crawler excavator dipper U template groove machining process, belong to the excavator boom technical field.
Background technology
At present; The dipper of excavator below 15 tons all adopts U template structure; U template circular arc place groove in process generally adopts the manual grinding mode, and is consuming time big, low precision; Not only reduced the efficient of producing, after assembling process in organize right difficulty because the error of manual grinding greatly also can cause.Because the arc groove is connected with preceding bearing, the quality of groove directly has influence on U template and preceding bearing weldquality.
Summary of the invention
The technical problem that the present invention will solve provides the hydraulic crawler excavator dipper U template groove machining process that a kind of crudy is good, production efficiency is high.
In order to solve the problems of the technologies described above, technical scheme of the present invention provides a kind of hydraulic crawler excavator dipper U template groove machining process, and it is characterized in that: this method is made up of following 2 steps:
Step 1: cushion block and alignment pin are installed on workbench, with two U templates of permanent magnetic chuck lifting to workbench, move the U template make it with alignment pin near, check that two U templates overlap fully after, locking pressure plate is located;
Step 2: use 45 ° of rose reamers of vertical machining centre, the speed of mainshaft is 650～900r/min, and the amount of feeding is 250～450mm/r, mills each the circular arc place groove on the U template successively, notices that front end leans on the centerline groove not mill.
A kind of hydraulic crawler excavator dipper U template groove machining process provided by the invention winches to self-control U template groove frock after with the U template through magnechuck; After the clamping and positioning; Use 45 ° of rose reamer cut; Once can process two parts, crudy is good and production efficiency is high, and is applicable to dissimilar hydraulic crawler excavators.
A kind of hydraulic crawler excavator dipper U template groove machining process provided by the invention has overcome the deficiency of prior art, has improved U template groove quality and production efficiency, simple to operate, safety and highly versatile.

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 hydraulic crawler excavator dipper U template groove machining process, it is characterized in that: this method is made up of following 2 steps:
Step 1: like Fig. 1～shown in Figure 4, cushion block 4 and alignment pin 5 are installed on workbench 1, with two U template 3 to workbench 1 of permanent magnetic chuck lifting, move U template 3 make it with alignment pin 5 near, check that two U templates 3 overlap fully after, locking pressure plate 2 is located;
Fig. 1 and LG6060 type hydraulic crawler excavator dipper U template 3a and the LG6150 type hydraulic crawler excavator dipper U template 3b of being respectively shown in Figure 3.
Step 2: like Fig. 5 and shown in Figure 6; Use 45 ° of rose reamers of vertical machining centre GR510, the speed of mainshaft is 650～900r/min, and the amount of feeding is 250～450mm/r; Mill each the circular arc groove 8 that need mill on the U template 3a shown in Figure 7 successively, notice that front end leans on centerline groove 7 not mill.Two U templates of this process 3a washes simultaneously, has improved production efficiency.
After the completion of processing,, guarantee that groove meets processing request with each groove of vernier caliper measurement.
