Technical field
A kind of elbow formula hand clamping device belongs to technical field of mechanical manufacturing equipment, is specifically related to a kind of clamping device of using for clamping mechanical processing parts.
Background technology
Machining refers to the process that by the various machinery appearance and size to workpiece or performance change.The machining of broad sense refers to the process that can manufacture a product by mechanical means; The machining of narrow sense refers to make of special mechanical equipments such as lathe, milling machine, drilling machine, grinding machine, stamping machine, die casting machines the process of part.For the machining of narrow sense, be the important operation step that is related to part processing precision to the clamping of part to be processed, and clamping device play vital effect for this step.But, existing clamping device is all 1:1 transfer function power, need very large clamping force could realize the clamping to part to be processed, this clamping mode has very significantly shortcoming: workman's working strength is large, and easily occur because active force is inadequate, clamped part do not have clamped and processes unsuccessfully, the waste of raw materials having caused.
Ways of addressing this issue is to provide very little active force of a kind of needs, just can obtain the clamping device of desirable clamping effect.But regrettably, in found data, do not find relevant product.
Utility model content
For the problems referred to above, the utility model has designed a kind of elbow formula hand clamping device, this binding clasp utilizes triangle of forces principle, only need a very little active force, just can obtain desirable clamping effect, not only can reduce workman's working strength, and can effectively avoid because clamped part is because active force is inadequate, do not have clamped and process the waste of raw materials that unsuccessfully caused.
The purpose of this utility model is achieved in that
A kind of elbow formula hand clamping device, comprise that the opening that is arranged on bottom is at " recessed " shape base of side, base top is provided with circular open, axle bed is seated in the opening of base, be connected with shutter housing with axle bed top outside screw, the position of shutter housing off-axis, is provided with circular open, inverse-T-shaped revolving body stretches out from the circular open of shutter housing by thrust bearing, and described revolving body bottom is provided with gap; The centre of axle bed has upper coarse and lower fine shoulder hole, the ladder position of shoulder hole is connected with pressure axis by compression spring, the position that pressure axis symmetrical centre is departed from described pressure axis top is provided with gap, between the gap of revolving body and the gap of pressure axis, is connected with elbow wall; Centre position, pressure axis bottom connects briquetting by the compression axis through axle bed shoulder hole, and clamped part is pressed in base openings bottom by briquetting.
Above-mentioned a kind of elbow formula hand clamping device, is provided with the revolving body limited screw of horizontal arrangement on the sidewall of described shutter housing, the sidewall along continuous straight runs that described revolving body limited screw withstands on revolving body moves.
Above-mentioned a kind of elbow formula hand clamping device, the gap of revolving body is positioned at the position of departing from revolving body symmetrical centre.The misalignment of revolving body
Above-mentioned a kind of elbow formula hand clamping device, described compression spring is compressive state under nature.
The beneficial effect of the utility model elbow formula hand clamping device is:
By spanner apparatus rotating revolving body, make the gap of revolving body act on elbow wall, known according to triangle of forces rule, in the time that elbow wall only departs from the very little angle of numerical value direction, it is a very little value that the stressed horizontal component of elbow wall is compared with vertical component, therefore very little active force of horizontal direction, will just have very large active force by the vertical direction.Therefore can realize to very little active force of revolving body, will obtain the clamping effect desirable to clamped part, not only can reduce workman's working strength, and can effectively avoid because clamped part is because active force is inadequate, do not have clamped and process the waste of raw materials that unsuccessfully caused.
Brief description of the drawings
Fig. 1 is the mechanical assembly drawing of the utility model elbow formula hand clamping device.
In figure: 1 base, 2 axle beds, 3 shutter housings, 4 revolving bodies, 5 thrust bearings, 6 pressure axis, 7 compression springs, 8 elbow walls, 9 compression axises, 10 briquettings, 11 clamped parts, 12 revolving body limited screws.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model detailed description of the invention is described in further detail.
Specific embodiment one
The elbow formula hand clamping device of the present embodiment, mechanical assembly drawing as shown in Figure 1.This elbow formula hand clamping device comprises that the opening that is arranged on bottom is at " recessed " shape base 1 of side, base 1 top is provided with circular open, axle bed 2 is seated in the opening of base 1, be connected with shutter housing 3 with axle bed 2 top outside screw, the position of shutter housing 1 off-axis, be provided with circular open, inverse-T-shaped revolving body 4 stretches out from the circular open of shutter housing 1 by thrust bearing 5, and described revolving body 4 bottoms are provided with gap; The centre of axle bed 2 has upper coarse and lower fine shoulder hole, the ladder position of shoulder hole is connected with pressure axis 6 by compression spring 7, the position that pressure axis 6 symmetrical centre are departed from described pressure axis 6 tops is provided with gap, between the gap of revolving body 4 and the gap of pressure axis 6, is connected with elbow wall 8; Pressure axis 6 centre positions, bottom are by connecting briquetting 10 through the compression axis 9 of axle bed 2 shoulder holes, and clamped part 11 is pressed in base 1 open bottom by briquetting 10.
