Abstract
The utility model relates to a clamping device, specifically to a positioning clamping device comprising a base body, a clamping jaw, a bolt and a resetting spring piece. The base body is formed by a vertical support and a horizontal support, the clamping jaw plays a role in supporting and clamping a workpiece on the lower surface of the workpiece, the bolt serves as a force applying device, and the resetting spring piece plays a role in resetting and supporting a driving end of the clamping jaw. The middle part of the clamping jaw is in hinge joint with the vertical support of the base body, the upper surface of the driving end of the clamping jaw is pressed against the lower end of the bolt; the bolt is connected with a thread of the horizontal support of the base body, the lower surface of the driving end of the clamping jaw is pressed against a supporting end of the resetting spring piece, and the resetting spring piece is fixed to the vertical support of the base body. The positioning clamping device is simple in structure and low in cost, is energy-saving and environment-friendly and is of high repairability.
Description
Technical field
The utility model relates to a kind of clamping device, is specifically related to a kind of positioning clamping device.
Background technology
In the machining manufacturing industry, positioning clamping device plays important effect, and it guarantees that the relative lathe of workpiece, cutter etc. are in correct position all the time, guarantees uniformity and the crudy of workpiece processing.
For location and the clamping of miniature workpiece, usually adopt artificial free-hand finishing in order to reduce cost, by utilizing lever, spring, pulley, cam, compound modes such as handle reach the effect of clamping work pieces, this wherein bolt drive jaw to come workpiece pressing be a kind of common clamping device.Though existing clamping device can satisfy the clamping demand of workpiece to a certain extent, but in the actual use, still exist following some shortcomings: 1, adopt traditional lever principle to need the direction of multiple conversions power to clamp effect with realization, cause its structure setting complicated; 2, for the general clamping requirement of miniature workpiece, if adopt hydraulic pressure or bigger force application apparatus structure such as pneumatic easily to cause the wasting of resources and environmental pollution; 3, the force application apparatus of integral structure wearing and tearing occur or damages in long-term use, is easy to cause the discarded of whole apparatus structure, and recoverability is not strong, cost is high.
The utility model content
The technical problems to be solved in the utility model provides a kind of simple in structure, energy-conserving and environment-protective, has stronger recoverability, the positioning clamping device that cost is low.
In order to solve the problems of the technologies described above, the utility model provides a kind of positioning clamping device, include matrix, described matrix is made of vertical support frame and horizontal stand, the workpiece lower surface is worked the jaw that supports with clamping action, bolt as force application apparatus, drive end to described jaw has the reseting spring leaf that resets with supporting role, wherein, the middle part of described jaw and the vertical support frame of matrix are hinged, and the drive end upper surface of described jaw and the lower end of described bolt offset, and described bolt is threaded with the horizontal stand of matrix, the drive end lower surface of jaw and the support end of reseting spring leaf offset, and described reseting spring leaf is fixed in the vertical support frame of matrix.
Tight a bolt, bolt moves down, drive end until its lower end and jaw offsets, the position that bolt is combined for the downward pressure of jaw drive end to make jaw with the support force that reseting spring leaf makes progress to this end driven end keeps relative stability, and workpiece is by firm clamping; Unclamp bolt, bolt moves up, until the drive end of its lower end and jaw from, bolt disappears for the downward pressure of jaw drive end thereupon, at this moment, the elastic force that reseting spring leaf makes progress for this drive end also exists, and its drive end and driven end all are rotation counterclockwise, thereby the lower surface that departs from workpiece makes workpiece released.
Adopt the positioning clamping device of technique scheme to have following advantage: 1, realize clamping effect owing to adopted bolt to cooperate with jaw, therefore simple in structure; 2, because the manual operation clamping device has replaced the big power source mechanism of energy consumption, so the energy-conserving and environment-protective of this clamping device; 3, owing to adopt simple screw bolt reinforcing, bolt is threaded with matrix, is convenient to reparation and replacing to force application apparatus, thereby reduces the cost of making and using.
As preferred version, consider convenience and the flexibility of swivel bolt, described bolt force side is provided with handle.
As preferred version, consider the stability of putting into workpiece, make the clamping better effects if of workpiece, described matrix vertical support frame is provided with to match with the matrix horizontal stand and forms the boss of pinch zones.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of the utility model embodiment positioning clamping device.
The specific embodiment
Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:
As shown in Figure 1, the utility model provides a kind of positioning clamping device, include matrix 1, matrix 1 is made of vertical support frame and horizontal stand, the workpiece lower surface is worked the jaw 2 that supports with clamping action, bolt 3 as force application apparatus, drive end to jaw 2 has the reseting spring leaf 5 that resets with supporting role, wherein, the vertical support frame of the middle part of jaw 2 and matrix 1 is hinged, and the drive end upper surface of jaw 2 and the lower end of bolt 3 offset, and bolt 3 is threaded with the horizontal stand of matrix 1, the drive end lower surface of jaw 2 and the support end of reseting spring leaf 5 offset, and reseting spring leaf 5 is fixed in the vertical support frame of matrix 1.In addition, bolt 3 force sides are provided with handle 4, and matrix 1 vertical support frame is provided with to match with the matrix horizontal stand and forms the boss of pinch zones.
Specifically be to use method to be: to tight a bolt 3, bolt 3 moves down, drive end until its lower end and jaw 2 offsets, the position that bolt 3 is combined for the downward pressure of jaw 2 drive ends to make jaw 2 with the support force that reseting spring leaf 5 makes progress to this end driven end keeps relative stability, workpiece is by firm clamping; Unclamp bolt 3, bolt 3 moves up, until the drive end of its lower end and jaw 2 from, bolt 3 disappears for the downward pressure of jaw 2 drive ends thereupon, at this moment, the elastic force that reseting spring leaf 5 makes progress for this drive end also exists, and its drive end and driven end all are rotation counterclockwise, thereby the lower surface that departs from workpiece makes workpiece released.
Above-described only is preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
