Abstract
The utility model relates to an enameled wire detector, in particular to a snap tester capable of quick snap test, which comprises a panel (1), an air cylinder (2) communicated with a high pressure air source, a mobile chuck (3) clamping the measured enameled wire and a fixing chuck (4). A piston (5) is arranged in the air cylinder (2) and a piston link (6) is arranged at the end part of the piston (5). The mobile chuck (3) is arranged on the piston link (6) and the fixing chuck (4) is arranged on the panel (1). A long hole (7) and a calibration (8) marked with the stretch rate are arranged on the panel (1) and a stop block (9) capable of adjusting the position so as to control the stretch rate is arranged in the long hole (7). A buffer cushion (10) is arranged on the stop block (9). The utility model has the advantages that the utility model can be used for carrying out the snap test so as to inspect the products conforming to the national standard BG/T4074 and the international standard IEC60851 and can also be used for doing the quick stretch test so as to inspect the products conforming to the U.S. standard NEMA. The utility model also has wide application range and can deliver multiple purposes as one machine.
Description
Technical field
The utility model relates to a kind of enameled wire detecting instrument, particularly a kind of jerk test instrument of doing tension test rapidly.
Background technology
Enameled wire detecting instrument--the jerk test instrument of domestic production at present, it generally is the principle that adopts pneumatic stretching, it includes panel, fixed chuck, mobile chuck and the cylinder that is communicated with high-pressure air source, piston is housed in the cylinder, and top land is equipped with piston rod, and mobile chuck is installed on the piston rod, fixed chuck is installed on the panel, and a slotted hole is arranged on the panel.During test, piston rod is broken the detected enameled wire that is fixed on the active chuck suddenly along slotted hole with the speed greater than 2 meter per seconds under the promotion of power, uses the paint film situation of lens examination enameled wire incision position then.Its weak point is can only do to jerk disconnected test, meets the product of standard GB/T4074 and international standard IEC60851 with detection; And can not do tension test rapidly, and can not detect the exported product that meets U.S. NEMA standard, this exported product needs to do thermal shock test again after the speed stretching of detected enameled wire with the 3.7-4.9 meter per second.Like this, original jerk test instrument just can not meet the demands.
Summary of the invention
The purpose of this utility model provides a kind of jerk test instrument of doing tension test rapidly, to solve the prior art above shortcomings.
The technical scheme that the utility model adopted is: the jerk test instrument that can do tension test rapidly includes panel, fixed chuck, mobile chuck and the cylinder that is communicated with source of the gas, piston is housed in the cylinder, top land is equipped with piston rod, mobile chuck is installed on the piston rod, and fixed chuck is installed on the panel, and a slotted hole is arranged on the panel, stretching end at panel is provided with the link stopper of adjustable position with the control stretching rate, is useful on the scale of mark extensibility on the panel of end that stretches.
The further technical scheme of the utility model is that block is provided with cushion pad.
The utility model has the advantages that both can do to jerk disconnected test, meet the product of national standard BG/T4074 and international standard IEC60851, can do tension test rapidly again, meet the product of Unite States Standard (USS) NEMA with check with check, applied widely, a tractor serves several purposes.
Description of drawings
Fig. 1 is a synoptic diagram of the present utility model.
Below in conjunction with accompanying drawing structure of the present utility model is described further.
Embodiment
Shown in the accompanying drawing 1: the jerk test instrument that can do tension test rapidly comprises panel (1), the cylinder that is communicated with high-pressure air source (2), clamp the mobile chuck (3) and the fixed chuck (4) of tested enameled wire, piston (5) is arranged in the cylinder (2), piston rod (6) is equipped with in piston (5) end, mobile chuck (3) is installed on the piston rod (6), fixed chuck (4) is installed on the panel (1), it is 10% that slotted hole (7) and mark extensibility are arranged on the panel (1), 20%, 30%, 40% and 50% scale (8), the block (9) of adjustable position with the control stretching rate is housed in the slotted hole (7), cushion pad (10) is arranged on the block (9).Block (9) can unclamp or tighten, can mobile block (9) when unclamping, and when tightening, can fixed stop (9).Do when jerking disconnected the test, link stopper (9) is moved to 50% place.When doing extensibility test rapidly,, block (9) is moved on on the corresponding scale (8) then by the extensibility requirement.When gases at high pressure promote piston (5) and piston rod (6) when advancing to the relevant position, piston (5) is run into block (9) and is promptly halted, and enameled wire promptly is stopped stretching, and cushion pad (10) then plays buffer action.
Claims (2)
1, a kind of jerk test instrument of doing tension test rapidly includes panel, fixed chuck, mobile chuck and the cylinder that is communicated with source of the gas, piston is housed in the cylinder, top land is equipped with piston rod, mobile chuck is installed on the piston rod, and fixed chuck is installed on the panel, and a slotted hole is arranged on the panel, it is characterized in that the link stopper of adjustable position with the control stretching rate being set, on the panel of end that stretches, be useful on the scale of mark extensibility at the stretching end of panel.
2, the jerk test instrument of doing tension test rapidly as claimed in claim 1 is characterized in that block is provided with cushion pad.
