Abstract
Screw rod drilling tool test bench is from big moment of torsion clamping device of centering relates to a clamping device, and including rocking handle, tong teeth, tong teeth seat, adjust lead screw, direction thick stick, end plate, base, tong teeth passes through on fixing bolt fixes two relative about tong teeth seats respectively, and the tong teeth seat presss from both sides tightly or loosens through adjusting lead screw control, leads through the direction thick stick simultaneously, adjusts the lead screw and is connected with the end plate respectively with direction thick stick both ends, and the end plate passes through fastening bolt to be fixed respectively in the base left and right sides, the rocking handle with adjust screw connection, it has adopted soon to opposite trapezoidal thread to adjust the both ends of lead screw. The utility model discloses can realize the automatic centering pressing from both sides tight in -process to antitorque ability reinforce can bear great moment of torsion.
Description
Technical field
The utility model relates to a kind of clamping device, is that a kind of screw rod drilling tool testing stand is from centering high pulling torque clamping device specifically.
Background technology
In the test process of petroleum geology industry helicoid hydraulic motor testing stand and other kinds test platform, the clamping of workpiece is vital link, can be used for the shaped article of clamping workpiece at present, comprises all kinds of bench vice, vice.Bench vice, vice are widely used, but have following shortcoming: 1, vice is many is used alone in shop assembled maintenance process, and clamping process does not have centering, can not be applied to test platform as parts; 2, bench vice is many uses in all kinds of stock-removing machine, because cutting force is little, so the moment of torsion that can bear is very limited.
Utility model content
In order to overcome the shortcoming that above-mentioned prior art exists, the purpose of this utility model is to provide a kind of screw rod drilling tool testing stand from centering high pulling torque clamping device, and it in clamping process, can realize automatic centering, and anti-twisting property is strong, can bear larger moment of torsion.
In order to solve the problem, the utility model is by the following technical solutions: helicoid hydraulic motor testing stand is from centering high pulling torque clamping device, it is characterized in that, comprise rocking handle, pincers tooth, pliers tooth base, adjusting screw, guiding thick stick, end plate, base, pincers tooth is separately fixed on two relative pliers tooth bases of left and right by set bolt, pliers tooth base controls clamping by adjusting screw or unclamps, led by guiding thick stick simultaneously, adjusting screw and guiding thick stick two ends respectively with end plate connection, end plate is separately fixed at the base left and right sides by fastening bolt, described rocking handle is connected with adjusting screw, the two ends of described adjusting screw have employed the contrary trapezoidal thread of rotation direction.
The beneficial effects of the utility model are:
1, because adjusting screw two ends have employed the contrary trapezoidal thread of rotation direction, easily can realize the uniformity of two pliers tooth base motion processes, realize automatic centering.
2, lead owing to have employed large diameter guiding thick stick, significantly can improve the overturn-preventing moment of clamping device, significantly improve operation torque.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described further:
Fig. 1 is front view of the present utility model;
Fig. 2 is sectional view of the present utility model;
In figure: 1 rocking handle, 2 pliers tooth bases, 3 pincers teeth, 4 adjusting screws, 5 guiding thick sticks, 6 end plates, 7 fastening bolts, 8 bases, 9 set bolts.
Detailed description of the invention
As Fig. 1, shown in Fig. 2, helicoid hydraulic motor testing stand is from centering high pulling torque clamping device, comprise rocking handle 1, pincers tooth 3, pliers tooth base 2, adjusting screw 4, guiding thick stick 5, end plate 6, base 8, pincers tooth 3 is separately fixed on two relative pliers tooth bases 2 of left and right by set bolt 9, pliers tooth base 2 controls clamping by adjusting screw 4 or unclamps, led by guiding thick stick 5 simultaneously, adjusting screw 4 is connected with end plate 6 respectively with guiding thick stick 5 two ends, end plate 6 is separately fixed at base 8 left and right sides by fastening bolt 7, described rocking handle 1 is connected with adjusting screw 4, the two ends of described adjusting screw 4 have employed the contrary trapezoidal thread of rotation direction.
During clamping work pieces, workpiece is put in the middle of two pincers teeth 3, shake rocking handle 1, rocking handle 1 drives adjusting screw 4 to rotate, because adjusting screw 4 two ends are respectively left hand thread and right-handed thread, so shake rocking handle 1 clockwise, two pliers tooth bases 2 move toward center position simultaneously, clamping work pieces, counterclockwise shake rocking handle 1, two pliers tooth bases 2 move toward both sides simultaneously, unclamp workpiece.After Workpiece clamping, because trapezoidal thread has auto-lock function, can ensure that, in whole test process, workpiece can not get loose.Guiding thick stick 7 in the helicoid hydraulic motor testing stand course of work, significantly can improve clamping device anti-twisting property.
The utility model is not only confined to above-described embodiment.
