Abstract
The utility model discloses a high-efficient adds clamping apparatus of electric power steering device casing, the anchor clamps body has four working faces, there is at least one station on every working face, the clamping mechanism of every working face is driven by independent hydraulic system, hydraulic system includes hydraulic cylinder and defeated oil pipe way all as to the inside of the anchor clamps body that the working face encloses, wherein, every work piece is pressed from both sides tightly by two the same hydro-cylinders, every station is including installing the tip locating piece on the working face, the main part locating piece, the assistance-localization real-time subassembly, install the valve body on the anchor clamps body. The clamp minimizes the occupied space of local single stations, maximizes the number of stations of the clamp, reasonably avoids interference between workpiece clamping mechanisms, and avoids interference of a machine tool rotary table, a main shaft, the clamp, a cutter and the like. The influence of the clamping and positioning mechanism on the deformation of the workpiece is verified by using finite element analysis, the deformation of the workpiece is minimum, the requirement on product precision is met, and the automation degree is high.
Description
Technical Field
The utility model relates to a machining technical field, concretely relates to high-efficient adds clamping apparatus of electric power steering device casing.
Background
The aluminum shell of the electric power steering device is a key part in the system, heart parts such as a worm gear and a worm of a transmission system are contained in the aluminum shell, and the connection with a vehicle body is born outside the aluminum shell. But the processing characteristics are more, the working procedure is beat-to-beat long, the bottleneck working procedure is formed, and the improvement of the productivity is restricted. Meanwhile, due to the fact that the shape is complex, the wall thickness is thin (the average wall thickness is 3.5 mm), clamping and positioning are difficult, clamping is prone to deformation, and the precision of a processed product is poor (the roundness of a hole is poor).
SUMMERY OF THE UTILITY MODEL
The utility model discloses aim at reduces the process beat through the innovation of anchor clamps structure is vice greatly, improves production efficiency, improves product quality simultaneously.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the high-efficiency machining clamp for the shell of the electric power steering device is characterized in that the clamp body is provided with four working faces, at least one station is arranged on each working face, a clamping mechanism of each working face is driven by an independent hydraulic system, each hydraulic system comprises a hydraulic oil cylinder and an oil conveying pipeline, the hydraulic system is arranged inside the clamp body enclosed by the working faces, each workpiece is clamped by two identical oil cylinders, each station comprises a small end positioning block, a large end positioning block, a pressing mechanism assembly and an auxiliary pressing assembly, and a valve body is arranged on the clamp body.
The end part of the clamp body is provided with a cover plate.
An energy accumulator is arranged in the clamp body.
And a pressure gauge is arranged on the clamp body.
The utility model has the advantages that: the fixture enables the occupied space of local single stations to be minimized, the number of the work stations of the fixture is maximized, interference between workpiece clamping mechanisms is reasonably avoided, interference of a machine tool rotary table, a main shaft, the fixture, a cutter and the like is avoided, and the maximization of the efficiency is achieved. The influence of the clamping and positioning mechanism on the deformation of the workpiece is verified by using finite element analysis, the deformation of the workpiece is minimum, the requirement on product precision is met, and the automation degree is high.

Detailed Description
The invention will be further explained with reference to specific embodiments.
As shown in fig. 1-2, the maximum effective space of the numerical control machine tool is fully utilized to arrange the fixture, the fixture body 1 is provided with four working surfaces, each working surface is provided with 4 stations, the total number of the working surfaces is sixteen, and the space of the machine tool is extremely utilized; the clamping mechanism of every working face is driven by independent hydraulic system, and hydraulic system includes that hydraulic cylinder 5 and defeated oil pipe way all are in the inside of the anchor clamps body that the working face encloses, and wherein, every work piece is pressed from both sides tightly by two the same hydraulic cylinder 5, adopts hydraulic pressure pressurize clamping mode and built-in type hydro-cylinder, and the oil duct is built-in inside the anchor clamps main part, and every work piece is pressed from both sides tightly with two the same hydro-cylinders, guarantees quick clamping efficiency, reduces the shared space of complementary unit simultaneously.
Each station comprises a small end positioning block 11, a large end positioning block 12 and a clamping mechanism which are arranged on a working surface, the clamping mechanism comprises a pressing mechanism component 10 and an auxiliary pressing component 7, and a valve body 2 is arranged on a clamp body. The end of the clamp body 1 is provided with a cover plate 20. An energy accumulator 21 is arranged in the clamp body, and a pressure gauge 15 is arranged on the clamp body.
The fixture enables the occupied space of local single stations to be minimized, the number of the work stations of the fixture is maximized, interference between workpiece clamping mechanisms is reasonably avoided, interference of a machine tool rotary table, a main shaft, the fixture, a cutter and the like is avoided, and the maximization of the efficiency is achieved. The influence of the clamping and positioning mechanism on the deformation of the workpiece is verified by using finite element analysis, the deformation of the workpiece is minimum, the requirement on product precision is met, and the automation degree is high.
