The utility model aims to provide a transmission shaft fixture which can be used to stably fix a transmission shaft and raise assembling efficiency. The transmission shaft fixture is characterized by comprising a fixture block, a hand wheel, a lead screw, a nut and a cylindrical support. The bottom of the cylindrical support is provided with a flange, the bottom of which is equipped with a bump. The nut is sleeved on the top of the support. One end of the lead screw is in a key joint with the hand wheel, and the other end of the lead screw is screwed in the nut. The fixture block is provided with a V-shaped groove, and the fixture block is arranged on the top of the lead screw. Preferably, the cylindrical support is fixed with the nut through screws. The utility model also provides a transmission shaft experiment table assembly with the application of the transmission shaft fixture.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly is used for folding up the anchor clamps with the fixed conveyor axle in the experiment of a kind of transmission shaft.The utility model also relates to the transmission shaft testing table assembly of these transmission shaft anchor clamps of a kind of application.
Background technology
At present, when torsional fatigue test platform is installed transmission shaft test exemplar, take the mode of manually assembling, by the auxiliary suspention of overhead traveling crane, transmission shaft is lifted to testing machine, then transmission shaft two end flanges are connected respectively with the testing machine two ends respectively.Because the transmission shaft quality is big, add that overhead traveling crane suspention can only flexible bundle transmission shaft, transmission shaft can about, left and right directions waves, and highly is difficult to control, and installs also very difficultly, work efficiency is low.
The utility model content
At deficiency of the prior art, the utility model aims to provide a kind of steadily fixed conveyor axle, improves the transmission shaft anchor clamps of efficiency of assembling.
The utility model also provides the transmission shaft testing table assembly of these transmission shaft anchor clamps of a kind of application.
In order to address the above problem, this kind transmission shaft anchor clamps is characterized in that comprising: fixture block, handwheel, screw mandrel, nut and cylindrical shape bearing;
The bottom of cylindrical shape bearing is provided with flange, and the bottom of flange is provided with projection, and nut sleeve is located at the top of bearing, and an end of screw mandrel is connected with the handwheel key, and the other end is screwed in the nut, and fixture block has V-shaped groove, and this fixture block is arranged on the top of screw mandrel.
Preferably, fix by screw between described cylindrical shape bearing and the nut.
A kind of transmission shaft testing table assembly of the present utility model, comprise: testing machine, testing machine stiff end, testing machine free end and trough of belt slide rail, testing machine is arranged on an end of trough of belt slide rail, the testing machine stiff end is connected with testing machine, the testing machine free end is arranged on the other end of trough of belt slide rail, this transmission shaft testing table assembly is characterised in that: also comprise above-mentioned transmission shaft anchor clamps, these transmission shaft anchor clamps are connected with the trough of belt slide rail by the projection of its bottom.
The beneficial effects of the utility model are: transmission shaft anchor clamps of the present utility model bottom has the rectangle projection, move along the center line of two end flanges of testing machine always at the center that can guarantee these anchor clamps, needn't adjust the left and right directions of transmission shaft, only adjust it and just get final product, install accurate, convenient.
Description of drawings
Fig. 1 is the structural representation of transmission shaft anchor clamps of the present utility model;
Fig. 2 is the structural representation of transmission shaft testing table assembly of the present utility model.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
As shown in Figure 1, transmission shaft anchor clamps of the present utility model, it comprises: fixture block 1, handwheel 3, screw mandrel 4, nut 6 and cylindrical shape bearing 7.The bottom of cylindrical shape bearing 7 is provided with flange, and the bottom of flange is provided with rectangle projection 71, is used for being connected with the trough of belt slide rail of transmission shaft testing table.This nut 6 is set in the top of bearing 7 and the shoulder pad structure is arranged, and only endoporus has perfect thread, and outer peripheral face is smooth, can guarantee with screw itself and bearing is convenient fixing.One end of screw mandrel 4 is connected by key 2 with handwheel 3, and the other end is screwed in the nut 6, and fixture block 1 has V-shaped groove, and this fixture block 1 is arranged on the top of screw mandrel.The outer wall that screw 5 passes cylindrical shape bearing 7 is connected with nut 6, and cylindrical shape bearing 7 and nut 6 are connected and fixed.
As shown in Figure 2, a kind of transmission shaft testing table assembly of the present utility model, it comprises: testing machine, testing machine stiff end 8, testing machine free end 12, trough of belt slide rail 11 and two above-mentioned transmission shaft anchor clamps 9, testing machine is arranged on an end of trough of belt slide rail, the testing machine stiff end is connected with testing machine, the testing machine free end is arranged on the other end of trough of belt slide rail, and these transmission shaft anchor clamps 9 are connected with the trough of belt slide rail by the projection 71 of its bottom.
During use, testing machine free end 12 is shifted out, the rectangle projection of two groups of transmission shaft anchor clamps 9 bottoms that assemble is put into trough of belt slide rail 11, again testing machine free end 12 is put into trough of belt slide rail 11, can finish whole assemblings of frock.
When transmission shaft is installed, at first two transmission shaft anchor clamps 9 and testing machine free end 12 are drawn to suitable position according to the length of transmission shaft 10, directly the two ends of transmission shaft 10 are positioned on the V-shaped groove on the two transmission shaft anchor clamps 9.When needs rose transmission shaft 10, the handwheel 3 that turns clockwise with screw mandrel 4 rotations, make screw mandrel 4 along nut 6 axially-movables, thereby the jack-up V-shaped groove was to suitable height by key 2; When needs reduce transmission shaft 10, be rotated counterclockwise handwheel 3 and get final product.
