Description
Technical field
The present invention relates to machining fixture field, more particularly, to a kind of machining fixture locking device.
Background technology
At present in field of machining such as gem, crystals, need the workpieces to be processed such as gem, crystal to pass through fixture locking
Locking, therefore, the clamping performance of fixture locking device is extremely important for device.As shown in figure 1, traditional gem machining fixture
Drive rod 100 one end of locking device is connected on cylinder piston rod 400, drive rod 100 and locking arm 200 clamping, locking arm
200 is hinged with lock 300；Cylinder piston rod 400 drives drive rod 100 to move downward, by drive rod 100 and locking arm 200
Between bayonet socket locking arm 200 is compressed, and simultaneously pass through locking arm 200 and lock 300 between buckle lock 300 clamping,
But, when cylinder internal gas pressure is not enough, whole device will produce related loosen, lead to latch 300 being in loosening state, simultaneously
Workpiece is in and loosens or half loosening state, the machining accuracy of impact workpiece, and produces a series of production safety problems.
In a word, current work piece holder locking device is primarily present both sides problem: first, existing fixture is in clamping work
Part can change with the change of the cylinder operation air pressure in system during being processed, and lead to workpiece to produce and get loose, simultaneously
Do not have a good locking effect it is ensured that the not process safety of the workpiece to be processed such as gem, crystal and machining accuracy；Its
Secondary, existing machining fixture locking device volume is larger, is not easy to install.
For above-mentioned technical problem, it is badly in need of providing a kind of locking property more good fixture locking device.
Content of the invention
It is an object of the invention to provide a kind of machining fixture locking device, this device is easily operated, and locking property is good, no
Easily get loose；The present invention can effectively improve working (machining) efficiency it is ensured that the machining accuracy of workpiece, improves the quality of production of workpiece, and
Ensure that production safety.
For achieving the above object, the present invention provide a kind of machining fixture locking device, including shell, lock and with gas
The drive rod that cylinder piston rod connects；It is provided with a self-locking mechanism that can lock lock between described lock and drive rod, described
One end of self-locking mechanism is hinged with drive rod, and the other end is hinged with lock；When drive rod activity downwards, self-locking mechanism is driven to live
Move and lock lock, when drive rod activity upwards, drive self-locking mechanism activity and unlock described lock.
As a further improvement on the present invention, described self-locking mechanism is formed by the first self-locking arm is hinged with the second self-locking arm,
Described first self-locking arm and the second self-locking arm are hinged with drive rod and lock respectively.
As the further improvement of the present invention, described second self-locking arm is provided with self-locking arm locking face, on described lock
It is provided with the lock locking face matching with self-locking arm locking face, when drive rod activity downwards, self-locking mechanism is locked by self-locking arm
To realize locking lock, when drive rod activity upwards, self-locking arm locking face departs from lock locking to tight face clamping lock button locking face
Face is to realize unlocking described lock.
As the further improvement of the present invention, the second self-locking arm in described self-locking mechanism and housing hinge.
As the further improvement of the present invention, described shell is provided with the position-limit mechanism making drive rod along lengthwise movement.
Beneficial effect
Compared with prior art, a kind of machining fixture locking device of the present invention, this device is easy to operate, producers
When clamping the workpiece to be processed such as gem, convenient to operation, workpiece locking force foot be locking property well it is not easy to loose
De-.In a word, the present invention effectively increases production efficiency, prevents from leading to appearance safety etc. to be asked because workpiece to be processed gets loose, splashes etc.
Inscribe the safety it is ensured that producing.
By description below and combine accompanying drawing, the present invention will become more fully apparent, and these accompanying drawings are used for explaining the present invention
Embodiment.

Specific embodiment
With reference now to Description of Drawings embodiments of the invention,.
Embodiment
, as shown in Fig. 2 is to 5, a kind of machining fixture locking device, including shell 3, lock for the specific embodiment of the present invention
Button 2 and the drive rod 1 being connected with cylinder piston rod 400；It is provided with one between described lock 2 and drive rod 1 and can lock lock
The self-locking mechanism 4 of button 2, one end of described self-locking mechanism 4 is hinged with drive rod 1, and the other end is hinged with lock 2；When drive rod 1 to
During lower activity, drive self-locking mechanism 4 activity and lock lock 2, when drive rod 1 activity upwards, drive self-locking mechanism 4 activity simultaneously
The described lock 2 of unblock.
As the improvement further of present embodiment, described self-locking mechanism 4 is by the first self-locking arm 41 and the second self-locking arm 42
Hinged composition, the first self-locking arm 41 and the second self-locking arm 42 are hinged by the first self-locking shaft 6, described first self-locking arm 41 and second
Self-locking arm 42 is hinged with drive rod 1 and lock 2 respectively.Described second self-locking arm 42 is provided with self-locking arm locking face 421, described lock
Button 2 is provided with the lock locking face 21 matching with self-locking arm locking face 421；When drive rod 1 downward activity, self-locking mechanism 4
Realize locking lock 2 by self-locking arm locking face 421 clamping lock button locking face 21, when drive rod 1 activity upwards, self-locking arm
Locking face 421 departs from lock locking face 21 to realize unlocking described lock 2.
Specifically, when present embodiment uses, when drive rod 1 is promoted upwards by cylinder piston rod 400, drive rod
1 moves up, and drive rod 1 drives the right-hand member of the first self-locking arm 41 to move up, and moves up in the right-hand member of the first self-locking arm 41
During, because the second self-locking arm 42 in described self-locking mechanism 4 is hinged with shell 3, now the second self-locking arm 42 is around itself
Second self-locking shaft 7 hinged with shell 3 rotates clockwise, and because lock 2 and the second self-locking arm 42 are articulated with lock axle 8, now locks
Button 2 is converted to releasing orientation.
When piston rod 400 drives drive rod 1 to move down, when the first self-locking arm 41 becomes horizontality, the second self-locking
Arm 42 also returns to horizontality, and the second self-locking arm 42 lock 2 clamps locking, now, does not produce the feelings of displacement in drive rod 1
Under condition, the first self-locking arm 41 no moment of torsion makes it produce rotation, and lock 2 is locked by self-locking mechanism 4.Therefore, the present invention make to be processed
The locking force foot of workpiece is it is not easy to get loose, and effectively increases production efficiency, and exclusion gets loose, splashes because of workpiece to be processed
Processing problems and a series of safety problems of producing.
In the present embodiment, described shell 3 is provided with the position-limit mechanism 5 making drive rod 1 along lengthwise movement.This position-limit mechanism 5
Drive rod 1 is made to produce upper and lower displacement in vertical direction；Described drive rod 1 is flake joint.Described drive rod 1 can use gas
Body pressure promotes, it is possible to use hydraulic drive, and power source is various, adapts to the different demands producing.
Above in association with most preferred embodiment, invention has been described, but the invention is not limited in enforcement disclosed above
Example, and modification, the equivalent combinations that the various essence according to the present invention are carried out should be covered.
