Description

Technical Field

[0001] The utility model relates to the technical field of processing tooling for construction machinery parts, in particular to a processing tooling for the stable support feet at the excavation end of an excavator-loader used on a horizontal machining center. Background Art

[0002] An excavator-loader is a construction machinery that can perform excavation and loading operations simultaneously, with multiple functions of an excavator and a loader, commonly known as a "two-in-one machine". During construction, the operator only needs to turn the seat to change the working end. An excavator-loader includes a power assembly, a loading end, and an excavation end, and the excavation end is provided with stable support feet. When machining the stable support feet by using an ordinary fixture to fix the workpiece by manually pressing the pressing plate, according to the structural characteristics requirements of the workpiece product, it is necessary to press and fix the side surface of the workpiece and perform end face drilling, side milling, drilling, and boring operations. This will inevitably bring problems such as difficult positioning and clamping of the workpiece, not only with high labor intensity, low processing efficiency, but also unstable processing quality and inability to meet the assembly requirements.

[0004] To achieve the above object, the processing tooling for the stable support feet at the excavation end of the utility model's excavating loader includes a fixture body 1, a base 2, a spacer block 3, a rotary clamping cylinder device 4, a connecting plate 5, a compact cylinder device 6, an adjusting limit block 7, and a reinforcing rib 9. The fixture body 1 is an integrally cast inverted T-shaped structure composed of a horizontal bottom plate and a vertical upright plate, and the reinforcing rib 9 is welded between the back of the vertical upright plate and the horizontal bottom plate. The base 2 is fixed on the horizontal bottom plate of the fixture body 1 by two hexagon socket head cap screws and is close to the front edge, for positioning the bottom end face and side face of the stable support foot workpiece 8. There are two rotary clamping cylinder devices 4, which are respectively fixed on the front vertical surfaces on the left and right sides close to the vertical upright plate of the fixture body 1 by four hexagon socket head cap screws. The connecting plate 5 is fixed on the left side surface of the vertical upright plate of the fixture body 1 by two hexagon socket head cap screws. The compact cylinder device 6 is fixed on the connecting plate 5 by two hexagon socket head cap screws. There are six spacer blocks 3, which are respectively fixed on the vertical upright plate of the fixture body 1 by one hexagon socket head cap screw, arranged in three rows of upper, middle, and lower, with one on each side of each row. The adjusting limit block 7 is fixed on the front vertical surface of the vertical upright plate of the fixture body 1 and close to the right side by two hexagon socket head cap screws, and its installation height is the same as that of the compact cylinder device 6. The base 2, the spacer block 3, the rotary clamping cylinder device 4, the connecting plate 5, the compact cylinder device 6, and the adjusting limit block 7 are all used to position and fix the stable support foot workpiece 8 on the fixture body 1.

[0005] The processing tooling for the stable support feet at the excavation end of the utility model's excavating loader has the following technical features and beneficial effects:

[0006] 1. The base 2 is used to position the bottom end face and side face of the stable support foot workpiece 8, and the rotary clamping cylinder device 4 and the compact cylinder device 6 are used to press and hold the stable support foot workpiece 8, which can greatly reduce the labor intensity of the operator, improve the processing efficiency, and avoid workpiece deformation caused by uneven pressing force due to differences in operator skills, thereby improving the yield of workpiece processing.

[0007] 2. The tooling has a simple and compact structure, and the manufacturing and maintenance costs are low. Description of the Drawings
