Description

A kind of loading machine rocking arm machined fixture
Technical field
The utility model relates to a kind of loading machine rocking arm machined fixture.
Background technology
Rocking arm is one of important building block for working device of loader, as shown in Figure 1, rocking arm comprises interior pasting board 1, outer pasting board 1, stiffener 1, rocking arm side plate 4, middle axle sleeve 5, shrouding 6, outer pasting board 27, stiffener 28 and interior pasting board 29 etc.In working device of loader system, by rocking arm and pull bar make scraper bowl and rotary ink tank hinged, and ensure the operating characteristic that keeping parallelism moves in scraper bowl lifting and decline process; Together with on rocking arm, bearing pin hinge mounted is passed through to connect with pull bar, rotary ink tank and swing arm respectively in three groups of holes, for making the translation performance in loading machine work reach optimum, require the pilot hole position between rocking arm and associated components to possess higher dimensional accuracy and positional precision, must ensure the Stability and veracity of product orientation and clamping in batch production, not allow to exist location and the mismachining tolerance of each pilot hole.
Traditional process for machining equipment adopts Simple positioning device to position rocking arm, periphery is equipped with fastening screw, scheme is more backward, during this device busy, locates, clamps comparatively loaded down with trivial details, operator's labour intensity is very big, owing to being screw rod hand-operated clamping, cannot tackle the phenomenon of the vibration of workpiece aggravation producing because of various situations in process, efficiency is low, cannot adapt to production in enormous quantities, and have potential safety hazard.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of loading machine rocking arm machined fixture with very high safety work coefficient and production efficiency.
In order to solve the problems of the technologies described above, the technical solution of the utility model has been to provide a kind of loading machine rocking arm machined fixture, it is characterized in that: comprise base, at the center of base, be provided with the heavy oil cylinder of square, transition press plate is locked on the heavy oil cylinder of square by self-control joint, on base, be furnished with two set product location and clamping elements, axle sleeve centration axis in the middle of every set product location and clamping element comprise, 3 support cylinders, the locating shaft that is placed in the corner oil cylinder on corner cylinder bearing and locates for product rotation, wherein, middle axle sleeve centration axis is arranged in the side of the heavy oil cylinder of square, at the rear of middle axle sleeve centration axis, be furnished with 1 support cylinder, at the rear of this support cylinder, be furnished with corner cylinder bearing, locating shaft is arranged in a side of corner cylinder bearing, remain the opposite side that 2 support cylinders are arranged in corner cylinder bearing.
Preferably, in the bottom of described base, be provided with 2 alignment pins.
The utility model adopts positioning principle and the clamping mode conforming to machining center equipment, by relevant auxiliary positioning element, product is positioned, the hydraulic system of being provided for oneself by machining center drives each positioning and clamping Hydraulic Elements, and utilize the pressing plate being arranged in each clamp base to implement to clamp action to product, realize accuracy and the stability of product orientation coordinate, the utility model is applicable to the manufacturing procedure of each tonnage loading machine rocking arm.
The utility model has the advantages that simple to operate, safety, efficiency gets a promotion, and is proven, this kind of method compared with adopting before manual device, the welding efficiency of separate unit improves 3 times.
Accompanying drawing explanation
Fig. 1 is loading machine rocking arm stereogram;
Fig. 2 is loading machine rocking arm machined fixture stereogram;
Fig. 3 is that loading machine rocking arm machined fixture is implemented operation top view;
Fig. 4 is that loading machine rocking arm machined fixture is implemented operation stereogram.
The specific embodiment
For the utility model is become apparent, hereby with preferred embodiment, and coordinate accompanying drawing to be described in detail below.
As shown in Figure 2, the loading machine rocking arm machined fixture that the utility model provides comprises base 10, on base 10, be equipped with two set product location and clamping elements, in the middle of being respectively, axle sleeve centration axis 11, support cylinder 12, corner oil cylinder 13 are arranged on corner cylinder supporting seat 14, and the locating shaft 15 of locating for product rotation; Base plate 10 centre positions are provided with the heavy oil cylinder 16 of square, by self-control joint 17, transition press plate 18 are locked on the heavy oil cylinder 16 of square, and the heavy oil cylinder 16 of square utilizes transition press plate 18 that clamping force is passed to 2 pressure strips 19; 2 alignment pins 20 with basic hole system interference fit below base 10.
Two described set product positioning and clamping elements are respectively 11,3 support cylinders 12 of middle axle sleeve centration axis, are placed in the corner oil cylinder 13 on corner cylinder bearing 14 and for product, rotate the locating shaft 15 of locating; On the heavy oil cylinder 16 of square, 1 transition press plate 18 is housed, utilizes transition press plate 18 that clamping force is passed to 2 pressure strips 19, pressure strip 19 compresses 2 processed products simultaneously; 2 alignment pins 20 are with basic hole system interference fit below base 10, and alignment pin 20 coordinates with the locating slot on machining center workbench, implement fast aligning and location.
Its using method is: as shown in Figures 3 and 4, it is positioning datum that product be take axle sleeve 5 in the middle of rocking arm by diagram display direction, middle axle sleeve 5 Internal hole positionings are determined on core pin 11 in middle axle sleeve, locating shaft 15 fully contacts location with tangent locate mode with rocking arm side plate 4, meanwhile, support cylinder 12 automatic capturings of product below, the depth of parallelism of guarantee product and machining center workbench; The corner oil cylinder 13 of settling in alignment pin 15 relative directions applies after clamping force, start the heavy oil cylinder 16 of square, utilize transition press plate 18 that clamping force is passed to 2 pressure strips 19, with this, reach enough carrying or the work progress of clamping dynamics to guarantee that product carries out on frock clamp.
