Description

Pole bend test device

Technical field

The present invention relates to conducting wires to produce detection technique field, specially pole bend test device.

Background technique

Conducting wire such as enameled wire or paper insulation stranded wire etc. are needed after the completion of production to its flexibility and attached Property tested, flexibility and adhesion have reacted winding wire through the outer active force such as Tensile, winding, bending or twisting When, the ability of adhesion is not cracked or is lost in insulation, standard GB/T/T 4074.3-2008 for flexibility and The detection of adhesion has detailed introduction, can be generally tested using pole coiling to be detected, Fig. 4 of the standard is just introduced Pole bend test device, by the way that two handles coaxial with pole are arranged, handle places sample equipped with ball bearing After on pole, by the way that two sides rotational handle, sample is bent 180 degree by the ball bearing on handle respectively, thus It is tested；Wherein the diameter of pole has regulation, such as paper insulation stranded wire in the standard of corresponding article Standard GB/T/T 7673.5-2008 in provide, paper insulation stranded wire is bent on the pole of predetermined outside diameter multiplying power After 180 degree insulating layer should not crack or without local protuberance, it is specified that outer diameter multiplying power are as follows: ZJ, ZJM:(10-11) times；ZJD:(6- 7) again；Namely sometimes can be different for the size of different conductor size poles, so above-mentioned pole bend test fills The conducting wire for being only applicable to a kind of size is set, when needing the pole using other sizes to be tested, it is necessary to using other Experimental rig leads to higher cost.

Summary of the invention

Aiming at the problem that traditional pole bend test device is unable to the conducting wire of suitable for multiple sizes, the present invention provides poles Bend test device can be used for the bend test of the conducting wire of sizes.

Its technical solution is such that pole bend test device comprising pedestal, the pedestal are connected with by bracket Fixing axle, the fixing axle are equipped with pole, are also rotatably equipped with handle in the fixing axle, pass through connecting rod on the handle It is connected with bearing, the pole is connected with limit plate towards described handle one end, and the pole is socketed far from described handle one end There is pole clamping plate, the conductor clamping being placed under the action of locking nut by pole clamping plate and limit plate on the pole, It is characterized by: the pole includes shell and core cylindrical, and the core and the fixed axis connection, the core It is socketed with the shell more than or equal to 1 outward, is socketed with the pole clamping plate, the shell on the outermost shell Including with tight lock part from the socket part to the fixing axle that the core body concentric socket part and extend from, the core and institute The conductor size that the outer diameter of shell detects as needed is stated to be configured.

It is further characterized by:

Regulating tank is provided on the handle, described connecting rod one end connects the bearing, and the connecting rod other end is connected with lock Tight screw rod, the tie down screw pass through the regulating tank, are locked the connecting rod by nut；

The core is wrapped up by inner most shell and the limit plate；

When the shell is more than or equal to two, be successively socketed with the shell outside the core, by external shell and The limit plate respectively wraps up internal shell；

The fixing axle is equipped with screw thread.

After with such a structure, when needing to change size, circle is removed according to required pole outer diameter accordingly The shell and pole clamping plate of stick, until the outer diameter of pole and the outer diameter of requirement are identical, the shell that can be removed the last one at this time Body is clamped conducting wire by locking nut as pole clamping plate, then carries out bend test by handle, and then can pass through One detection device carries out bend test to the conducting wire of sizes.

Specific embodiment

As shown in Figure 1, Figure 2, the pole bend test device that Fig. 3 shows comprising pedestal 1, pedestal 1 are connected with solid by bracket 2 Dead axle 3, fixing axle 3 are equipped with pole 4, and handle 5 is also rotatably equipped in fixing axle 3, is connected on handle 5 by connecting rod 6 Bearing 7, pole 4 are connected with limit plate 8 towards 5 one end of handle, and pole 4 is socketed with pole clamping plate 9 far from 5 one end of handle, passes through Pole clamping plate 9 and limit plate 8 are placed on the clamping of the conducting wire 11 on pole 4, aforementioned specific structure under the action of locking nut 10 It is similar with the structure used in the standard being previously mentioned in background technique, in addition to being conveniently connected and fixed axis 3 equipped with screw thread, circle Stick 4 includes that shell 4-1 and core 4-2 cylindrical, core 4-2 are connect with fixing axle 3, is socketed with and is greater than outside core 4-2 The shell equal to 1 is socketed with pole clamping plate 9 on outermost shell 4-2, and shell 4-1 includes concentric with core 4-2 The outer diameter of socket part 4-11 and the tight lock part 4-12 extended from socket part 4-11 to fixing axle 3, core 4-2 and shell 4-1 according to The conductor size for needing to detect is configured.

After with such a structure, when being tested using maximum outside diameter, conducting wire 11 can be placed on pole 4 and be led to It crosses pole clamping plate 9 to be clamped, then so that such as Fig. 2 of conducting wire 11 is bent 180 degree by bearing 7 by rotational handle 5, thus and conventional Bend test device equally carries out bend test, when needing to change size, pole clamping plate 9 can be removed, according to required Pole outer diameter remove the shell 4-1 of pole 4 accordingly, until the outer diameter of pole 4 and the outer diameter of requirement are identical, at this time such as Fig. 4 It is shown to be clamped the shell 4-1 that the last one is removed to conducting wire 11 by locking nut 10 as pole clamping plate, then Bend test is carried out by handle 5, and then bend test can be carried out by conducting wire of the detection device to sizes.

In addition, being provided with regulating tank 5-1, connecting rod on handle 5 to make the bearing 7 on handle 5 be preferably bonded conducting wire 11 6 one end connect bearing 7, and 6 other end of connecting rod is connected with tie down screw, and tie down screw passes through regulating tank 5-1, will even by nut Extension bar 6 is locked, and allows up and down adjustment position in the range of regulating tank 5-1 of bearing 7 by tie down screw and nut.

Core 4-1 is wrapped up by inner most shell 4-2 and limit plate 8；When shell 4-1 is more than or equal to two, It is successively socketed with shell 4-1 outside core 4-2, is respectively wrapped up internal shell by external shell and limit plate 8； Furthermore it is possible to it is threadedly coupled shell 4-1 with fixing axle 3, it is more stable.

In addition, can increase between shell 4-1 or pole clamping plate 9 and conducting wire to be preferably clamped to conducting wire 11 If backing plate, damage wires 11 are prevented, meanwhile, although the section of conducting wire is that the round present apparatus is preferably applied to flat wire in figure.

More than, it is merely preferred embodiments of the present invention, but scope of protection of the present invention is not limited thereto, it is any It is familiar with the people of the technology within the technical scope disclosed by the invention, any changes or substitutions that can be easily thought of, should all cover at this Within the protection scope of invention.Therefore, protection scope of the present invention should be subject to the protection scope in claims.
