Abstract

The utility model discloses a clamp for grinding a small outer circle of an eccentric sleeve. The clamp comprises a base and a fixing sleeve, wherein the base and the fixing sleeve are connected and fixed through a locating pin, a counter platform which is the same with the eccentric sleeve in appearance is arranged on the fixing sleeve in an eccentric mode, and the counter platform is provided with two locating pins. A clamping screw is arranged on the side wall of the fixing sleeve. The clamp limits the rotational degree of freedom of workpieces through a rivet hole locating pin and a grinding hole locating pin, and ensures that elements of the workpieces are located at accurate positions, and the clamping screw on the side face limits the movement degree of freedom of the workpieces. The eccentric outer circle needing to be machined is located in the center of the clamp, and the eccentric degree of the clamp can be adjusted according to a measurement result. The positions of machined products are good in precision, requirements for a machine tool are low, and even an ordinary universal cylindrical grinding machine can meet the requirements, so that cost is greatly reduced. The clamp is high in quality of the machined products, easy to operate, low in requirements for labor skills of workers, and capable of being popularized in a large-scale mode and greatly improving production efficiency.

Description

A kind of eccentric bushing grinds little cylindrical anchor clamps
Technical field
The utility model relates to a kind of eccentric bushing and grinds little cylindrical anchor clamps.
Background technology
A kind of eccentric bushing has two eccentric circular holes and a biasing post as shown in Figure 1, 2.The biasing post cylindrical ground add man-hour figure, because the processing request height of eccentric excircle, there is very high requirement size, shape, position, and difficulty of processing is big.Requirement height to lathe has increased cost of investment, has increased the cost of product virtually, and efficiency has been subjected to very big influence.
Summary of the invention
The utility model purpose is to provide a kind of accurate positioning, clamping conveniently, and the eccentric bushing of being convenient to machine tooling grinds little cylindrical anchor clamps.
The utility model adopts following technical scheme for achieving the above object:
A kind of eccentric bushing grinds little cylindrical anchor clamps, it is characterized in that: it comprises base and fixed cover; Described base and fixed cover are connected and fixed by alignment pin, and off-centre is provided with the heavy stand identical with the eccentric bushing profile on the described fixed cover, and described heavy stand is provided with two alignment pins.
It is further characterized in that: described fixed cover sidewall is provided with clamping screw.
The utility model is according to six point location principles of anchor clamps, the rivet hole alignment pin, and the rotary freedom of grinding out alignment pin restriction workpiece, and guarantee that each key element of workpiece is in correct position, the clamping screw restriction workpiece movement free degree of side.The eccentric excircle that need process is positioned at the center of anchor clamps.The offset of anchor clamps can also be adjusted according to measurement result.The product space degree precision that processes is good, and to the requirement reduction of lathe, common universal cylindrical grinder can be competent at, and greatly reduces cost; The product quality height that processes, and simple to operate requires to reduce to workman's labour skill, can large-scale promotion, improved production efficiency greatly.
Description of drawings
Fig. 1 is the eccentric bushing side cutaway view.
Fig. 2 is the eccentric bushing front view.
Fig. 3 is the utility model profile.
Fig. 4 is the utility model vertical view.
The specific embodiment
A kind of eccentric bushing grinds little cylindrical anchor clamps shown in Fig. 3,4, and it comprises base 1 and fixed cover 2; Described base 1 and fixed cover 2 are connected and fixed by alignment pin 3, and off-centre is provided with the heavy stand identical with the eccentric bushing profile on the described fixed cover 2, and described heavy stand is provided with two alignment pins.Described fixed cover 2 sidewalls are provided with clamping screw 6.
The utility model is by rivet hole alignment pin 4, and grinding out alignment pin 5 limits the rotary freedom of workpiece, and guarantees that each key element of workpiece is in correct position, the clamping screw restriction workpiece movement free degree of side.The eccentric excircle that need process is positioned at the center of anchor clamps.The offset of anchor clamps can also be adjusted according to measurement result.The product space degree precision that processes is good, and to the requirement reduction of lathe, common universal cylindrical grinder can be competent at, and greatly reduces cost; The product quality height that processes, and simple to operate requires to reduce to workman's labour skill, can large-scale promotion, improved production efficiency greatly.
