Description

Fixed frock Technical Field The technical scheme relates to the technical field of fixture tools, in particular to a fixing tool. Background The fixed tool, also called a fixture tool, is a key tool for fixing and positioning a workpiece in mechanical manufacturing and machining, so that the workpiece can keep a stable and accurate position in the machining process, a customized solution is provided for different workpiece shapes and machining requirements, the machining precision is improved, the production efficiency is improved, and the operation safety is ensured. The existing traditional fixed fixture is applied to automatic production line production organized around a rotating table, a plurality of fixed fixture assemblies are installed on the rotating table, and when the fixed fixture assemblies sequentially pass through a plurality of processing or assembling stations, it becomes extremely difficult to maintain consistent and accurate positioning of all workpieces at each station, because workpieces of different types have differences in appearance, sizes and key positioning characteristics (such as positioning holes and bolting holes), one set of fixture optimized for specific workpieces cannot be suitable for other workpieces, when the workpiece types need to be switched on the production line, operators have to frequently and manually adjust positioning elements on the fixed fixture according to samples of new workpieces, and the operation is troublesome and inconvenient. Disclosure of Invention The technical scheme provides a fixed frock in order to improve current traditional fixed frock and lead to the problem that the adjustment is loaded down with trivial details, use inconvenience because of manual debugging efficiency is lower in automated line production. The technical scheme aims at realizing the following steps: the utility model provides a fixed frock, its installs rotationally sets up in the turning to bench of frame for cooperate unlocking device to carry out centre gripping location to the work piece, include: the bearing base is movably arranged on the steering table, and fixed pressure parts are arranged on two sides of the bearing base; The fixed clamp is movably arranged on the bearing base and used for clamping a workpiece, two sides of the fixed clamp are respectively extended with an abutting part which is arranged corresponding to the fixed pressure part, and the fixed clamp can be switched between a locking state and an unlocking state; The limiting device comprises a limiting frame and an elastic piece, the limiting frame is in relative sliding fit with the bearing base, two ends of the elastic piece respectively lean against the limiting frame and the bearing base, the elastic force of the elastic piece pushes the limiting frame to lean against the fixed mounting clamp, so that the abutting part has a tendency of abutting against the fixed pressing part, and the fixed mounting clamp is in a locking state at the moment; Under unlocking device's drive, bear the weight of the base with take place to remove between the spacing, make the butt portion with the constant pressure portion separates, and the constant dress anchor clamps are in the unblock state this moment. According to the technical scheme, when the fixed fixture is normally used, in the operation flow, the unlocking device drives the bearing base and the limiting frame to move, so that the bearing base moves upwards relative to the limiting frame, the bearing base moves upwards to compress the elastic piece based on the position fixing of the limiting frame, the abutting portion and the fixed pressing portion are separated, the fixed fixture clamps the sample block and is freely and movably adjusted to a preset position, when the locking driving piece releases thrust, the bearing base falls and drives the fixed fixture to synchronously descend, the elastic piece is gradually released, the limiting frame abuts against the fixed fixture through the elastic piece, the abutting portion abuts against the fixed pressing portion through elastic force, and therefore the fixed fixture is mechanically locked, movement of the fixed fixture is limited, locking and unlocking of the fixed fixture are automatically controlled through the driving piece, manual debugging is reduced, operation efficiency is improved, the elastic piece is buffered, stable and accurate motion is ensured, and the fixed fixture is more convenient to use. Preferably, the fixing clamp comprises: a bottom plate arranged on the bearing base, the bottom plate having the constant pressure part; a clamping driving member provided on the base plate; two clamping jaw members which are arranged on the clamping driving member in a sliding way, the clamping jaw members are provided with a plurality of clamping convex points for abutting against a workpiece, the clamping driving piece drives the two clamping jaw pieces to be close to or far away from each other.
