Description
Technical field
The present invention relates to machining equipment field, more particularly to a kind of parts fixing device.
Background technology
It is used for fixing processing object during machine-building, is allowed to occupy correct position, is constructed or detected with receiving
Device is generally referred to as fixture, also known as fixture.In a broad sense, appointing during workpiece making, inspection or maintenance process
What process for device that is rapid, easily and safely installing workpiece, all can be described as fixture.Such as welding fixture, inspection jig,
Assembling jig, machine tool fixture etc..
In the prior art, bench vice is one kind in universal fixturing, is essential clamping device on vice bench.Although
Bench vice can clamp large volume of workpiece, while be capable of providing enough chucking powers, but for dimensional accuracy it is higher zero
Component, in the case where not using other easers package parts, when being clamped by bench vice, the jaw of bench vice is different
Position unbalance stress, the dimensional accuracy for be easy to causeing parts are destroyed.
Invention content
In for the above-mentioned prior art, for the higher parts of dimensional accuracy, wrapped up not using other easers
In the case of parts, when being clamped by bench vice, the jaw different location unbalance stress of bench vice be easy to cause parts
The problem of dimensional accuracy is destroyed, the present invention provides a kind of parts fixing devices.
To solve the above problems, a kind of parts fixing device provided by the invention solves to ask by following technical essential
Topic：A kind of parts fixing device including bottom plate, fixes fixture block, active fastening block and for pushing active fastening block to fixed fixture block
The pushing meanss of side movement, bottom plate are in strip, and the fixed fixture block is fixed on one end of bottom plate, the promotion of the pushing meanss
Along the length direction of bottom plate, the both sides of bottom plate are both provided with the sliding slot along floor length direction, the active fastening block in direction
On be provided with two pieces of sliding blocks coordinated respectively from different sliding slots, the mating surface that the side of the sliding slot and the bottom surface of sliding block are formed is
Arcwall face, and in the depth direction of sliding slot, the position peak of the arcwall face is located at openend to the bottom end of sliding slot of sliding slot
Between；Each side of bottom plate is both provided with two sliding slots, and two sliding slots in bottom plate homonymy respectively positioned at the upper end of bottom plate and
Lower end；The top and bottom width of the bottom plate differs, and fixed both fixture block and pushing meanss and the connection mode of bottom plate are equal
To be detachably connected form.
Specifically, in Yi Shang structure, by setting sliding block in the both sides of active fastening block, the sliding block coordinates with sliding slot, can
Realize that the sliding slot of bottom plate both sides is to active fastening block during active fastening block is pushed to move to fixed fixture block by pushing meanss
Into row conductor, active fastening block both sides move distance is avoided to differ, the situation for forming uneven chucking power on parts is caused to go out
Now, in this way, Yi Shang structure is when completing parts clamping, conducive to the uniformity of each point stress on clamping face.
The mating surface formed using the side of upper hopper chute and the bottom surface of sliding block can pass through more than arc as the structure setting of arcwall face
Shape face limits active fastening block and is slided in stress to the width direction of bottom plate, conducive to this clamping device fixing card during the work time
Block and the stability of active fastening block relative position；Meanwhile can avoid accumulating dust thereon with upper arc surface, conducive to active fastening block with
The fit precision of bottom plate.
In more than structure, for various sizes of parts, if element size is smaller, in fixed fixture block and active fastening block
Be sized to it is larger in the case of, in fact it could happen that when this caliper clamps parts, parts be entirely located in promotion dress
The unilateral side with active fastening block position is put, although homonymy move distance does not differ in this way, this structure can play limitation active fastening block
Situation occur, but during permanent use, due to active fastening block and/or bottom plate both sides unbalance stress, cause activity
The flank wear excessive velocities of fixture block and/or bottom plate, influence the fit precision between this caliper component.Structure provided by the invention
In, it is differed, while the shape of a sliding slot is respectively provided on the side of bottom plate upper and lower sides by the upper and lower sides width for being set as bottom plate
Formula convenient for the size according to parts, selects suitable width of jaw, the selection of more than width of jaw can be by selecting on bottom plate
Side or the sliding slot of downside coordinate the active fastening block of different in width and fixed fixture block, by fixed fixture block, pushing meanss and active fastening block
Three is installed on the upside of bottom plate or the form of downside simultaneously, in this way, may be such that the parts in jaw are located at promotion dress
Put on the extended line of motion path, even using active fastening block and the position of pushing meanss as boundary, avoid active fastening block unilateral side by
Power.
Further technical solution is：
As a kind of simple way of realization of pushing meanss, the pushing meanss include threaded rod, threaded block and turning handle, institute
It states threaded block to be fixed on bottom plate, threaded rod is threadedly coupled with threaded block, and the axis direction of threaded rod is parallel to the length of bottom plate
Direction, turning handle are fixed on threaded rod, and active fastening block is located between fixed fixture block and pushing meanss.In more than structure, in screw thread
During bar rotates, the end of threaded rod applies motive force to active fastening block, and the turning handle is used to that threaded rod to be driven to rotate.
There is the specific implementation loosened as a kind of, the screw thread on the threaded rod and threaded block is closely-pitched
Screw thread.
Enter sundries in mating surface to avoid fixture block and sliding slot, influence the cooperation of active fastening block and bottom plate or influence activity
Felt is provided in the mating surface of the smoothness that fixture block is slided along sliding slot, the active fastening block and sliding slot.
