The purpose of the present invention is to provide a kind of single-stages to assemble loop resistance test tool, to solve to assemble pull rod to single-stage
The difficult problem of assembly test.
To achieve the above object, the technical solution of single-stage assembly loop resistance test tool of the present invention is：Single-stage fits back into
Road resistance test tooling includes pressure equipment and load transfer device setting up and down, and load transfer device includes that mandril and top are set mounted in pressure
The standby spring between mandril, the pull rod top pressure cooperation that the mandril is used to assemble with single-stage.
The load transfer device guiding is assemblied in positioning sleeve, and the bottom of positioning sleeve offers the bottom outlet passed through for mandril.
The load transfer device further includes the gland and pressing plate being located between pressure equipment and spring, and gland is matched with pressing plate top pressure
It closes, pressing plate is installed on outside mandril, and the side that cooperation is oriented to positioning sleeve of gland is equipped with scale value.
The tooling further includes frame body, and the frame body includes top plate and pedestal, and the positioning sleeve is fixed on the base, pressure
Equipment is fixed on top plate.
The fastening nut for clam member upper surface is installed on the mandril, gland, which is equipped with, accommodates fastening nut
Space.
The spring includes the inside and outside inner spring and outer spring being set with.
The pedestal includes positioning plate, bottom plate and the spaced side gusset between positioning plate and bottom plate or so.
Positioning plate is equipped with the mounting hole for installing the positioning sleeve, and positioning sleeve is welded in mounting hole.
The beneficial effects of the invention are as follows：It is located at the spring below pressure equipment in load transfer device in the pressure for receiving pressure equipment
Mandril is transmitted the force to while power, mandril and the pull rod top pressure of single-stage assembly coordinate.Spring-compressed is set to carry out analog equipment single-stage
The working condition of assembly, when the equipment that presses pushes specific range, single-stage assembly reaches operating position.Pass through dedicated test work
Dress solves the problems, such as difficult to single-stage assembly pull rod assembly test.
The side that cooperation is oriented to positioning sleeve of gland is equipped with scale value, by directly observing the scale value energy on gland
Enough know gland moves down distance, convenient for control.
Description of the drawings
Fig. 1 is the structure chart for the specific embodiment that single-stage of the present invention assembles loop resistance test tool.
Specific implementation mode
The specific embodiment of the single-stage assembly loop resistance test tool of the present invention, as shown in Figure 1, the tooling includes along upper
The frame body that lower direction extends, frame body includes top plate 1 and the pedestal below top plate, passes through supporting rod 2 between top plate 1 and pedestal
Connection.The jack 3 for exporting downward pressure is fixed on top plate 1,3 lower section of jack is equipped with for transmitting downward pressure
Load transfer device.Load transfer device includes mandril 10 and the spring that is set in outside mandril 10, further includes pressing plate 6 of the top pressure in spring upper end
And gland 4 of the top pressure on pressing plate 6, spring include the inner-outer sleeve inner spring 7 set of installing and outer spring 8, spinning on mandril 10
There are fastening nut 5, fastening nut 5 to be used for the upper surface of clam member 6, gland 4 is equipped with the space for accommodating fastening nut 5.Top
The spring base 11 for fixed spring lower end is integrally formed on bar 10, the bottom of positioning sleeve 9 offers bottom outlet 15, and mandril 10 passes through
Bottom outlet 15 is connected with the pull rod that single-stage is assembled.The positioning sleeve 9 of upper end opening is fixed on pedestal, the guiding of gland 4 is slidedly assemblied in
In the upper end opening of positioning sleeve 9, the side for coordinating with positioning sleeve 9 of gland 4 is equipped with scale value, and 4 top pressure of gland is being pressed
On plate 6,6 top pressure of pressing plate is in the upper end of spring, and the lower end of spring is by 11 block of spring base on mandril 10.Pedestal includes positioning plate
12, bottom plate 14 and the spaced side gusset in left and right 13 between positioning plate 12 and bottom plate 14.Positioning plate 12, which is equipped with, to be used
In the mounting hole for installing the positioning sleeve 9, positioning sleeve 9 is welded in mounting hole.
When in use, the pedestal of tooling is fixed up first, make fitted position of the spring on mandril 10 reach 76 ±
0.2 compressive state is then placed in positioning sleeve 9, and jack 3 is made to press downwards, drives gland 4 to move down, pushing tow pressing plate 6
So that spring further compresses, 10 stress of mandril moves down, and to which the pull rod of pushing tow single-stage assembly moves down, is observed in folding process
Scale value on gland 4, according to the specific range for being required to learn jack and pushing of the size of single-stage assembly, i.e. gland 4
When being moved to specific scale value, the size of single-stage assembly reaches definite value requirement, and single-stage assembly reaches operating position, stops pressure.
At this moment staff assembles the resistance value in circuit by apparatus measures single-stage, judges whether loop resistance is exceeded, whole to complete
A test process.During the test, the interior outer spring of single-stage assembly compresses under the action of jack, and worker need to only control thousand
The size that jin top makes single-stage assemble reaches definite value, easy to operate simple, time saving and energy saving, ensure that assembly technical requirement, improves
Working efficiency.
In other embodiments, the pressure equipment such as other hydraulic cylinders or the cylinder in addition to jack can also be used.
In other embodiments, the scale value on gland can also not be used, pressure can be known by other measurement methods
The distance of the downward top pressure of equipment.
