Concentric double-ended self-locking clamp

Abstract

The invention relates to a concentric double-ended self-locking clamping and shaft-coupling tool in the field of mechanical application and medical treatment, and the clamp is used for solving the problems that the conventional clamp is mainly centered by the axis of a cone, a shaft-coupling end has less possibility of being self-locked and is easily uncoupled, the working status is unstable, and the vibration amplitude is large. The concentric double-ended self-locking clamp mainly comprises a shaft sleeve and two self-centering lock nuts, wherein the shaft sleeve is hollow and provided with slots at two ends. Self-centering lock nuts are respectively sleeved outside the front end and rear end of the shaft sleeve; connecting threads are formed on the outer surface of the slotted shaft sleeve; an internal hollow pipeline is highly concentric with the external threads; locking threads are formed in the two self-centering lock nuts; and the slotted shaft sleeve and the two self-centering lock nuts are used for achieving the purpose of locking an original power shaft with a connected article in a dual-effect manner though the threads. The concentric double-ended self-locking clamp is simple in structure, easy to operate, convenient to use, and applicable to connecting and fitting of a precise tool which needs self-locking clamping and concentric positioning with an instrument.

Description

technical field [0001] The invention relates to a precision instrument connection device in the field of mechanical application and medical treatment, in particular to a concentric double-head self-locking clamp. Background technique [0002] At present, there are many types of fixtures in China, mainly relying on the centering connection of the cone shaft. The coupling end cannot be self-locking, the concentric connection of the non-taper shaft is difficult, the working state is unstable, and the vibration amplitude is large during operation. It is mostly used in large-scale equipment, such as Automobile fixtures, lathe fixtures, drilling machine fixtures, tooling fixtures, etc. With the advancement of science and technology in various fields, the equipment is developing towards precision, and the requirements for the equipment connection device - fixture are gradually increasing, especially the demand for high concentricity fixtures in mechanical applications and medical f...

Problems solved by technology

[0002] At present, there are many types of fixtures in China, mainly relying on the centering connection of the cone shaft. The coupling end cannot be self-locking, the concentric connection of the non-taper shaft is difficult, the working state is unstable, and the vibration amplitude is large during operation. It is mostly used in large-scale equipment, such as Automobile fixtures, lathe fixtures, drilling machine fixtures, tooling fixtures, etc.

With the advancement of science and technology in various fields, the equipment is developing towards precision, and the requirements for the equipment connection device - fixture are gradually increasing, especially the demand for high concentricity fixtures in mechanical applications and medical fields is gradually increasing, and some concentric fixtures are used. It is suitable for precision instruments, but its structure is complex, there are many consumables, the operation is cumbersome, it cannot be self-locking, and most of them are single-head fixtures, and there are few double-head fixtures, so the practicability is weak
