Description

Bridge clamp

Technical Field

The utility model relates to a check out test set field especially relates to an electric bridge anchor clamps.

Background

According to the national standard, in the production process of metal wires, direct current resistance measurement is required to be carried out on metal conductors and wire cores of wires and cables, and the resistance of a test sample is generally measured by adopting a four-terminal measurement method, and the detection is usually carried out by a bridge resistance detector to measure the conductor resistance value of a certain length of wires or cables. The wire is typically clamped and energized using a bridge clamp. However, if the cable or the cable is long in the experimental process, the intermediate position of the cable or the cable, especially the cable, may sag due to its own weight, so that the cable or the cable to be detected is not straight, thereby affecting the detection accuracy.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that overcome exist among the prior art not enough, provide a bridge anchor clamps, it has the advantage that can help improving the degree of accuracy.

The utility model discloses a realize through following technical scheme: the utility model provides an electric bridge anchor clamps, includes the base, fixes the scale on the base and fixes the electrode holder at the base both ends, the base surface is close to the electrode holder at both ends and is located the both sides punishment of scale do not the rigid coupling have two sets of bracing pieces, the inside standing groove that is equipped with of base, it is connected with reciprocal lead screw to rotate between the surface of bracing piece and standing groove, threaded connection has the sliding block on the reciprocal lead screw, and the rigid coupling has the layer board between four sliding blocks, and the surperficial rigid coupling of layer board has the cushion, be equipped with drive assembly in the standing groove, the rotation of the.

Further, drive assembly includes servo motor, and servo motor fixes in one side of base, and servo motor's main shaft runs through the base and extends to the standing groove in, is fixed with first bevel gear on being close to servo motor's the reciprocal lead screw, is fixed with the second bevel gear with first bevel gear meshing on servo motor's the main shaft, all is fixed with the belt pulley on four bracing pieces, has cup jointed the belt on the belt pulley of adjacent both sides.

Furthermore, two vertical second scales are fixed on the surface of the supporting plate, one of the two vertical second scales is fixed at the position close to the center of the supporting plate, and the other second scale is fixed at the position close to the electrode chuck.

The utility model has the advantages that: like this at first through the electrode chuck at both ends press from both sides tight back this moment make reciprocal lead screw rotate through drive assembly, reciprocal lead screw rotates and can drive sliding block and layer board and reciprocate to make the cable butt of cushion and flagging part and upwards lift up it, guaranteed the depth of parallelism, thereby help improving measuring degree of accuracy.

Detailed Description

In order to make those skilled in the art better understand the technical solution of the present invention, the present invention will be further described in detail with reference to the accompanying drawings and preferred embodiments.

As shown in the figure, the utility model discloses a base 1, fix scale 2 on base 1 and fix the electrode holder 3 at base 1 both ends, the electrode holder 3 that base 1 surface is close to both ends and the both sides department that is located scale 2 respectively the rigid coupling has two sets of bracing pieces 4, the inside standing groove 5 that is equipped with of base 1, it is connected with reciprocal lead screw 6 to rotate between bracing piece 4 and standing groove 5's the surface, threaded connection has sliding block 7 on the reciprocal lead screw 6, and the rigid coupling has layer board 8 between four sliding block 7, and layer board 8's surface rigid coupling has cushion 9, be equipped with drive assembly in the standing groove 5, drive assembly drive reciprocal lead screw 6's rotation.

Further, the driving assembly comprises a servo motor 10, the servo motor 10 is fixed on one side of the base 1, a main shaft of the servo motor 10 penetrates through the base 1 and extends into the placing groove 5, a first bevel gear 11 is fixed on a reciprocating screw 6 close to the servo motor 10, a second bevel gear 12 meshed with the first bevel gear 11 is fixed on the main shaft of the servo motor 10, belts 13 are fixed on four support rods 4, and belts 13 are sleeved on the belts 13 on two adjacent sides. The servo motor 10 can firstly drive the second bevel gear 12 to rotate so as to drive the first bevel gear 11 to rotate, so that the reciprocating lead screw 6 can rotate, the reciprocating lead screws 6 on two sides can be simultaneously rotated through the belt 13 and the belt 13 wheel, the speed can be controlled by the servo motor 10, the position precision is very accurate, and the accuracy of the lifting height of the cushion block 9 is improved.

Further, two vertical second scales 152 are fixed on the surface of the supporting plate 8, wherein one second scale 152 is fixed near the center of the supporting plate 8, and the other second scale 152 is fixed near the electrode chuck 3. The actual height of the cable at the center can thus be referenced during the raising by the cable height measured close to the second scale 152 of the electrode chuck 3, so that the cable height close to the center is as high as possible at the same height as the cable height at the end points.

The utility model has the advantages that: like this at first through the electrode chuck 3 at both ends press from both sides tight back this moment make reciprocal lead screw 6 rotate through drive assembly, reciprocal lead screw 6 rotates and can drive sliding block 7 and layer board 8 and reciprocate to make the cable butt of cushion 9 and flagging part and lift up it upwards, guaranteed the depth of parallelism, thereby help improving measuring degree of accuracy.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
