Description
Technical field
The present invention relates to a kind of fixture that is exclusively used in the test of gate valve closing member combination broach.
Background technology
In prior art, to detect the intensity of gate valve be all after the body of bolt that is connected by gate valve and with gate valve connects for gate valve closing member combination broach test, whether the connecting portion that adopts puller system to test gate valve and body of bolt reaches criterion of acceptability, if puller system pulling force process is until fracture, and fracture location occurs on the body of bolt body of rod, the intensity of gate valve is up to standard, if fracture position on gate valve with connecting portion body of bolt, the insufficient strength of gate valve.Present gate valve is mostly cross section and is trapezoidal shape wide at the top and narrow at the bottom, but not rectangle, the two sides of gate valve are not parallel, therefore in the time that gate valve is fixed on to one end of puller system, being not easy fixing steadily generally has several fixed forms, and the one, as shown in Figure 5 gate valve two sides are cut after flat fixing again; The 2nd, on gate valve, weld as shown in Figure 6 a club in order to fixing; The 3rd, directly in the middle of gate valve, bore a hole in order to fixing as shown in Figure 7, above three kinds of common modes will be fixed on and on puller system, all have defect in order to gate valve, gate valve is cut to flat or perforation in the middle of gate valve, all the stress structure of gate valve will directly be destroyed, the intensity of gate valve will directly be had influence on, to such an extent as to have influence on the last testing result of gate valve, and club of welding is in order to fixing, in welding process, because high temperature also will, to the material production chemical change of gate valve itself, finally also will have influence on the testing result of gate valve.
Summary of the invention
In order to overcome the deficiencies in the prior art, the invention provides the fixture that is exclusively used in the test of gate valve closing member combination broach that a kind of original form that does not change gate valve can facilitate, directly gate valve be fixed securely.
In order to address the above problem, the present invention is by the following technical solutions: a kind of fixture that is exclusively used in the test of gate valve closing member combination broach, comprise clamp base, described clamp base top the right and left is respectively provided with a spill bayonet socket, and described two spill bayonet sockets are symmetrical set, the inner side of each spill bayonet socket is equipped with a chopping block, described chopping block is embedded on corresponding spill bayonet socket, chopping block is hard material, a compact heap is respectively close in chopping block inner side, clamp base below is provided with top board movable up and down, described top board movable up and down is connected with the telescopic oil cylinder that clamp base below is provided with, it is upwards movable that described top board can promote compact heap, the face matching with compact heap in the inner side of each chopping block is oblique, described compact heap connects and coordinates and can obliquely slide along oblique with oblique face, the slipping plane of oblique the composition "eight" shape in inner side of two chopping blocks, two compact heaps can upper and lower oblique slip along the slipping plane of "eight" shape, before and after each spill bayonet socket, both sides are provided with fixed head, described two fixed heads that are positioned on same spill bayonet socket are clamped both sides before and after compact heap, and the sliding tray while forming compact heap slip, two opposed facing medial surfaces of compact heap are back slope, two back slopes are inverted "eight" shape structure, the back slope top of compact heap is also provided with the anti-skidding boss of protrusion.
The invention has the beneficial effects as follows: the chopping block of establishing spill bayonet socket and embed hard material in clamp base can increase the local strength of the pressure-acting face of pedestal in the time carrying out tensile test, prevent compact heap extrusion clamp pedestal, make clamp base local deformation, slipping plane and two opposed facing medial surfaces of compact heap of oblique the composition "eight" shape in inner side of two chopping block chopping blocks are back slope, two back slopes are inverted "eight" shape structure, that gate valve in order to be trapezoidal shape wide at the top and narrow at the bottom at pair cross-section is while carrying out tensile test, two opposed facing medial surfaces of compact heap are inverted "eight" shape structure can be in the time clamping gate valve, more large area and gate valve contact gripping, clamping force to greatest extent can be provided, and the slipping plane of oblique the composition "eight" shape in the inner side of two chopping block chopping blocks is in order to carry out in process in tensile test, along with the increasing compact heap of pulling force clamps gate valve and moves up with gate valve, now compact heap is upward to slip along "eight" shape slipping plane, in sliding process, two compact heap relative positions dwindle gradually, thereby cause compact heap to increase gradually the snap-in force of gate valve, reach the object that gate valve is clamped, clamp base below is provided with the top board can the up and down telescopic oil cylinder being provided with clamp base below being connected, for before not clamping gate valve completely at fixture, compact heap upwards can be pushed to the position that gate valve need to clamp and close compact heap and tentatively clamp gate valve, and the back slope top of compact heap arranges the anti-skidding boss of protrusion, for before not clamping gate valve completely at compact heap, while preventing from upwards pulling gate valve, between gate valve and compact heap, failing to reach enough friction force drives compact heap to move up together, thereby cause compact heap to fail to clamp gate valve before gate valve deviates from the middle of two compact heaps, anti-skidding boss can match with the cocked bead of upper end, gate valve clamping section, the butt power that provided compact heap to move up with gate valve before compact heap does not clamp gate valve, therefore this fixture that is exclusively used in the test of gate valve closing member combination broach can facilitate in the original form that does not change gate valve, directly gate valve is fixed on puller system securely.
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
