Abstract
The utility model discloses a quick clamping device for connecting a screw thread member, which mainly comprises a bridge structure, a split nut mechanism and a handle, wherein a bridge comprises an upper bridge and a lower bridge, and the split nut comprises an upper split nut and a lower split nut which are connected by a hinge; and the upper and lower split nuts are fixed on the upper and lower bridges. When the quick clamping device is used, the upper bridge is opened, a threaded part of a measured object is put in a semi-circular threaded groove of the lower split nut, and the upper bridge is closed, accordingly, internal threads of the upper and lower split nuts are meshed with external threads of the measured object to form stable coaxial connection. The quick clamping device for connecting the screw thread member provides an advanced installation mode, the assembly and disassembly are quick to save man-hour, the assembly quality can be ensured, and the skill requirements for operators is low. The quick clamping device for connecting the screw thread member is especially for large volume production tests.
Description
Technical field:
The utility model relates to a kind of rapid-mounted device that is used for the connecting thread rod member, belongs to the quick machinery technical field of structures that is installed.
Background technique:
All be thread connecting mode greatly in the present mechanical connection.Plurality of advantages such as thread connecting mode has firm, flexible for installation, convenient and highly versatile, therefore the annex of many big machinery devices all adopts this mode to connect.The utility model has designed a kind of rapid-mounted device of connecting thread rod member according to a kind of testing apparatus of use for diesel engine final controlling element.
Object that this testing apparatus is surveyed is a kind of electromagnetic actuator of threaded rod member, and this final controlling element need be connected with pulling force sensor, and traditional Placement is used nut and other mechanical device is connected.Because need to change after the electromagnetic actuator test is finished, use traditional Placement can cause the dismounting difficulty, waste time and energy, greatly influenced the working efficiency of test, and if install not in placely when mounted or have when installing deviation may cause test data inaccurate even can damaged screw.Therefore in conjunction with existing testing apparatus and the machinery technology etc. that is installed, we propose a kind of quick and convenient, installing/dismounting is simple, automaticity is high rapid-mounted device that is used for the connecting thread rod member.
The model utility content:
The purpose of this utility model is to overcome the be connected dismounting difficulty of technology of existing nut, and inaccurate shortcoming is installed, and a kind of rapid-mounted device that is used for the connecting thread rod member is provided,
The purpose of this utility model solves by the following technical programs:
A kind of rapid-mounted device that is used for the connecting thread rod member, described rapid-mounted device comprise pedestal, last crane span structure, following crane span structure, go up half nuts, following half nuts and are connected hinge; Described crane span structure down is fixed on above the pedestal, and following half nuts is arranged on down in the middle of the crane span structure; The described half nuts of going up is arranged in the middle of the crane span structure.
Described crane span structure one end down is provided with the connection hinge, and last crane span structure flexibly connects with following crane span structure by connecting hinge.
The described free end of going up crane span structure is provided with the folding handle.
The described half nuts of going up is provided with identical internal thread with following half nuts inside.
The angle of thread of described internal thread is 60 degree.
This device mainly is made up of portal structure, half nuts mechanism and handle.Crane span structure is divided into crane span structure and following crane span structure, and half nuts is divided into half nuts and following half nuts, connects with hinge, and upper and lower half nuts is fixed on the upper and lower crane span structure.Open crane span structure during use, the helical thread portion of measured article is put in down in the semicircle thread groove of half nuts, crane span structure on the closure, the internal thread of upper and lower half nuts and the engagement of the outside thread of measured article form firm coaxial connection.
To go up the lower nut machining screw that is fixed together by original on the designing and manufacturing technique of half nuts, and change into and be processed into an integral body, use linear cutting machine edge of bed midline incision again.Because thread angle is 60 degree angles, when the screw thread member of measured article produces axial tension, can produce a radial component to half nuts, firmly mesh for guaranteeing the half nuts and the screw thread member of measured article, we will about crane span structure on surface grinding machine, together grind thickness.Two clamping plate are fixed on down on the crane span structure, when last crane span structure inserts, form the zero clearance and fix, bigger frictional force has guaranteed the firm engagement of half nuts.
This device is a kind of advanced person's a mounting type, can ensure the quality of products, and can save man-hour again, and is lower to operator's technical ability requirement, is specially adapted to produce in enormous quantities test.
Description of drawings:
Fig. 1 is a principle of device structural drawing of the present utility model;
Fig. 2 is that device of the present utility model uses schematic representation.
Wherein: 1 is last crane span structure; 2 are following crane span structure; 3 are following half nuts; 4 is last half nuts; 5 is the device pedestal; 6 for connecting hinge; 7 are the folding handle; 8 is connecting object.
Embodiment:
Below in conjunction with accompanying drawing the utility model is done and to be described in further detail:
Referring to Fig. 1-2, a kind of rapid-mounted device that is used for the connecting thread rod member, described rapid-mounted device comprise pedestal, last crane span structure, following crane span structure, go up half nuts, following half nuts and are connected hinge; Described crane span structure down is fixed on above the pedestal, and following half nuts is arranged on down in the middle of the crane span structure; The described half nuts of going up is arranged in the middle of the crane span structure.
Described crane span structure one end down is provided with the connection hinge, and last crane span structure flexibly connects with following crane span structure by connecting hinge.
The described free end of going up crane span structure is provided with the folding handle.
The described half nuts of going up is provided with identical internal thread with following half nuts inside.
The angle of thread of described internal thread is 60 degree.
At first, will connect pedestal according to the position dimension of applicable object is fixedly mounted on the test bench; Then, regulate the screw thread member part of applicable object, the following half nuts on making it and being installed in down crane span structure closely contacts; At last, closing up crane span structure will go up half nuts and following half nuts and be interlocked.The screw thread member of applicable object and half nuts formation zero clearance is fixed like this, and bigger frictional force has guaranteed the firm engagement of half nuts.
Above content is to further describing that the utility model is done in conjunction with concrete preferred implementation; can not assert that embodiment of the present utility model only limits to this; for the utility model person of an ordinary skill in the technical field; under the prerequisite that does not break away from the utility model design; can also make some simple deduction or replace, all should be considered as belonging to the utility model and determine scope of patent protection by claims of being submitted to.
