Description
Technical field
The utility model relates to frock technical field, especially a kind of clamping tool.
Background technology
Existing miniature workpiece carries out adding man-hour, need to carry out repeatedly resetting to miniature workpiece, one adopts bolt and pressing plate etc. to fix miniature workpiece, more complicated in the process of clamping, and another kind adopts to be undertaken carrying out clamping to miniature workpiece by the clamp system of hydraulic control, hydraulic system structure is complicated, noise is large, and needs oil pump oil transportation, and the oil in hydraulic system easily leaks into ground, cause working environment relatively more severe, and this clamp system cost by hydraulic control is higher.
Utility model content
The technical problems to be solved in the utility model is: add adopt man-hour bolt and pressing plate etc. to fix miniature workpiece to solve existing miniature workpiece, more complicated in the process of clamping, or employing causes by the clamp system of hydraulic control the problem that working environment is relatively more severe and cost is high, a kind of clamping tool is now provided, utilizes the dead point in frock to realize the clamping to workpiece.
The utility model solves the technical scheme that its technical problem adopts: a kind of clamping tool, comprise pedestal, mount pad, rocking bar and clamping bar, described mount pad is fixed on described pedestal, the both sides of described pedestal are extended with first protruding and the second projection respectively, connecting rod is provided with between described clamping bar and described rocking bar, the two ends of described connecting rod respectively with described clamping bar and rocking bar hinged, described clamping bar and described second protruding hinged, described rocking bar and described first protruding hinged, described connecting rod is positioned at the position hinged with rocking bar and is extended with handle, described rocking bar and connecting rod point-blank time, the top contact of described handle and described first projection, workpiece is placed between clamping bar and pedestal, pull handle until rocking bar and connecting rod point-blank, now clamping bar is just by Workpiece clamping, the line of two pin joints on clamping bar is vertical with pedestal, at this moment mount pad, clamping bar, between connecting rod and rocking bar, the position of connecting rod and rocking bar conllinear is exactly position, dead angle, no matter workpiece has great power to clamping bar, connecting rod all can not be made to start.
For the ease of clamping highly different workpiece, further, described clamping bar is provided with connector, described connector is provided with screwed hole, the bolt matched with it is provided with in described screwed hole, during swivel bolt, the distance between adjustable bolt and pedestal.
Preferably, the groove caved inward is provided with between described first projection and the second projection.
Preferably, described first height of projection is lower than the height of the second projection.
The beneficial effects of the utility model are: the new clamping tool of this practicality only needs when clamping work pieces to pull spanner, until the top contact of spanner and the first projection, now connecting rod and rocking bar conllinear, no matter workpiece has great power to clamping bar, connecting rod all can not be made to start, the utility model structure is simple, convenient and swift during use, workpiece can be clamped firmly.

Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of clamping tool, comprise pedestal 1, mount pad 2, rocking bar 3 and clamping bar 4, described mount pad 2 is fixed on described pedestal 1, as shown in Figure 3, the both sides of described pedestal 1 are extended with the first protruding 5 and second projection 6 respectively, the groove 11 caved inward is provided with between described first protruding 5 and second projection 6, described first protruding 5 height are lower than the height of the second projection 6, connecting rod 7 is provided with between described clamping bar 4 and described rocking bar 3, the two ends of described connecting rod 7 respectively with described clamping bar 4 and rocking bar 3 hinged, described clamping bar 4 is hinged with described second projection 6, described rocking bar 3 is hinged with described first projection 5, as shown in Figure 4, described connecting rod 7 is positioned at the position hinged with rocking bar 3 and is extended with handle 8, described rocking bar 3 and connecting rod 7 point-blank time, the top contact of described handle 8 and described first projection 5, workpiece is placed between clamping bar 4 and pedestal 1, pull handle 8 until rocking bar 3 and connecting rod 7 point-blank, now clamping bar 4 is just by Workpiece clamping, the line of two pin joints on clamping bar 4 is vertical with pedestal 1, at this moment mount pad 2, clamping bar 4, between connecting rod 7 and rocking bar 3, connecting rod 7 is exactly position, dead angle with the position of rocking bar 3 conllinear, no matter workpiece has great power to clamping bar 4, connecting rod 7 all can not be made to start.
As shown in Figure 1, described clamping bar 4 is provided with connector 9, described connector 9 is provided with screwed hole, the bolt 10 matched with it is provided with in described screwed hole, during swivel bolt 10, the distance between adjustable bolt 10 and pedestal 1, is convenient to clamp highly different workpiece.
Operation principle:
Workpiece is placed between clamping bar 4 and pedestal 1, pull handle 8 until the top contact of handle 8 and the first projection 5, now rocking bar 3 and connecting rod 7 are point-blank, clamping bar 4 is just by Workpiece clamping simultaneously, the line of two pin joints on clamping bar 4 is vertical with pedestal 1, at this moment mount pad 2, clamping bar 4, between connecting rod 7 and rocking bar 3, connecting rod 7 is exactly position, dead angle with the position of rocking bar 3 conllinear, no matter workpiece has great power to clamping bar 4, connecting rod 7 all can not be made to start, during the top contact of handle 8 and the first projection 5, rocking bar 3 and connecting rod 7 are point-blank, effectively prevent staff to pull handle 8 and deviate from dead-centre position.
Above-mentioned is enlightenment according to desirable embodiment of the present utility model, and by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
