Abstract
The utility model discloses an eccentric thread cam clamp which comprises a clamping platform and a U-shaped seat, the clamping platform is connected with a first supporting rod of the U-shaped seat, a hole drilling guide sleeve is arranged on a second supporting rod of the U-shaped seat, a locating check block is arranged on the left side of the clamping platform, a spline shaft is movably connected on the clamping platform opposite to the front opposite face of the U-shaped seat, an eccentric cam and a handle are connected on the spline shaft in sequence, and threads are arranged on the vertical face of the eccentric cam. According to the eccentric thread cam clamp, a workpiece can be simply clamped and located with manual force, the operation is convenient, external power is not needed any more, and energy sources are saved.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly a kind of eccentric screw thread cam anchor clamps.
Background technology
Workpiece during such as boring, needs first clamping and positioning usually before processing, existing general clamping mode in usefulness mainly contains hydraulic pressure, air pressure or electronic control etc., and clamping force is big, the precision height, but all need consume certain energy by outer power.
The utility model content
For solving the problems of the technologies described above, it is a kind of simple in structure, easy to operate that the utility model provides, by manually firmly getting final product the eccentric screw thread cam anchor clamps of clamping and positioning workpiece.
For achieving the above object, the technical solution of the utility model is: a kind of eccentric screw thread cam anchor clamps, comprise and clamp platform, U-shaped seat, clamping platform links to each other with first pole of U-shaped seat, second pole of U-shaped seat is provided with the boring guide pin bushing, clamps the platform left side and is provided with position block, relatively the right opposite of U-shaped seat and be positioned to clamp on the platform and be connected with splined shaft, be connected with eccentric cam and handle on the splined shaft in turn, the vertical plane of eccentric cam is provided with screw thread.
The beneficial effects of the utility model are: easy to operate by manually firmly can the clamping and positioning workpiece, and need not again to have saved the energy by outer power.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure: clamp platform 1, U-shaped seat 2, first pole 21, second pole 22, boring guide pin bushing 3, position block 4, splined shaft 5, eccentric cam 6, vertical plane 61, handle 7.
The specific embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the utility model is described further.
Embodiment:
As shown in Figure 1, a kind of eccentric screw thread cam anchor clamps, comprise and clamp platform 1, U-shaped seat 2, clamping platform 1 links to each other with first pole 21 of U-shaped seat 2, second pole 22 of U-shaped seat 2 is provided with boring guide pin bushing 3, clamps platform 1 left side and is provided with position block 4, relatively the right opposite of U-shaped seat 2 and be positioned to clamp on the platform 1 and be connected with splined shaft 5, be connected with eccentric cam 6 and handle 7 on the splined shaft 5 in turn, the vertical plane 61 of eccentric cam 6 is provided with screw thread.
Operation principle of the present utility model is: workpiece is put in and clamps on the platform 1, the back side is by first pole, 21 location of U-shaped seat 2, the left side is by position block 4 location, the place ahead is then by turning handle 7, drive eccentric cam 6 by splined shaft 5 and rotate, the vertical plane 61 by eccentric cam 6 when going to certain blocks clamping work pieces.In addition, on the vertical plane 61 of eccentric cam 6, by screw thread is set, strengthen friction, thereby increase clamping force.
