Description

Technical Field

[0001] The invention relates to the technical field of high-frequency spark machine calibration, in particular to a high-frequency spark machine calibration device. Background Art

[0002] High frequency spark machine is a fast and continuous withstand voltage test method, mainly used for withstand voltage test of rubber and plastic insulated wires, or rubber and plastic insulated wire cores of sheathed wire and cable products, generally suitable for products with voltage level of 1000V and below. Due to its simple equipment and fast speed, it is widely used in manufacturers.

[0003] When a high-frequency spark machine is used to test a cable, the cable is usually passed through the spark machine bead chain, with the bead chain used as an electrode. The speed at which the wire passes through the electrode ensures that the total contact time between any point on the wire and the electrode is not less than 18 positive and negative peak values ​​of the power supply voltage, and then the cable is subjected to a voltage withstand test.

[0004] In the prior art, high-frequency spark machines are generally provided with holes on both sides to facilitate the insertion of cables, which are usually pushed into the interior of a bead chain to make contact with the cables. However, in this process, due to the different thicknesses of the cables, thinner cables can be completely wrapped by the bead chain assembly according to a predetermined route, but for thicker cables, more of the cable may not be wrapped in the bead chain, thereby affecting the test accuracy of the spark machine for the cable. It is also inconvenient to artificially limit the insertion of cables of different thicknesses into the spark machine bead chain at different positions. Summary of the invention

[0005] In view of the shortcomings of the prior art, the purpose of the present invention is to provide a high-frequency spark machine calibration device to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. Through the cooperation between the limit assembly and the base, the limit assembly can drive the base to move upward, and the cable is sent into the base and then pushed into the interior of the bead chain assembly. Since there is a certain height difference between the clamped arc plate and the base, there will be a certain interval between the bottom of the cable and the base. The excess length of the bead chain assembly enters the mutual grooves of the base, and cables of different thicknesses are maintained in the middle position of the bead chain assembly, so that there is sufficient contact surface for voltage resistance testing, which is convenient for calibrating the horizontal position of the cable before testing cables of different thicknesses, so as to improve the accuracy of the test.

[0007] Furthermore, baffles are provided on both sides of the top of the base, and the bottom of the baffles is in extrusion contact with the base, an insertion strip is fixed on the top of the baffle, a sliding frame is fixed on the mounting frame of the bead chain assembly at the position corresponding to the insertion strip, and the insertion strip slides out of the sliding frame.

[0008] Furthermore, a guide plate is fixed to the bottom of the outer side of the baffle, and the guide plate is tilted upward toward the side of the delivery inlet. Slide grooves are symmetrically opened on the inner wall of the front end of the protective shell, and the guide plate slides along the slide grooves.

[0009] Furthermore, the limit assembly also includes a plug plate, two groups of plug plates are slidably plugged on both sides of the spark machine body, a bidirectional screw is rotatably installed between the two groups of plug plates through bearings, a connecting plate is meshingly sleeved on the surface of the bidirectional screw, and the connecting plate is fixedly connected to the outer side of the arc plate.

[0010] Furthermore, a telescopic rod is fixed on the side of the mounting block facing the arc plate, and the extended end of the telescopic rod is fixed to the outer side of the arc plate, an insertion rod is fixed on the inner side of the mounting block, and the insertion rod slides into the interior of the spark machine body, and the insertion rod and the insertion plate are inserted into the interior of the spark machine body and are connected to springs.

[0016] Beneficial effects of the invention: A high-frequency spark machine calibration device of the invention comprises a spark machine body; a control button; a protective shell; a feeding port; a slit window; a moving slot; a flat plate; a sliding slot; a limit assembly; an inserting plate; a bidirectional screw; a vertical column; a convex block; a connecting plate; a mounting block; a telescopic rod; an arc plate; an inserting rod; a transmission assembly; a rotating plate; a sliding rod; a transmission belt; a reset spring; a slot; a bead chain assembly; a base; a baffle; an inserting strip; a guide plate; a connecting frame; a sliding frame; a vertical plate;

[0017] 1. After the arc plate of the present invention clamps the cables passing through both sides of the protective shell, it moves outward to straighten the cables. At this time, due to the height difference between the arc plate and the base, the bottom of the cable is not in direct contact with the base. The cable enters the interior of the bead chain assembly, and the bottom of the bead chain assembly moves along the arc groove of the base and wraps around the bottom of the cable, thereby avoiding a large blank position of the cable that is not in contact with the bead chain assembly.

[0018] 2.

After the plug-in limit is lost, the plug plate drives the bidirectional screw and the arc plate to move outward. At this time, the arc plate is adjusted to a slightly clamped state. As the arc plate moves, the cable is straightened to keep the cable in a straight state and avoid bending.

[0019] 3. The present invention is driven by a transmission belt, and the rotation of the bidirectional screw drives the connecting plate to move in opposite directions synchronously. The two arc blocks are close to limit the cables of different thicknesses. When in the extrusion and clamping state, they can move to both sides to clamp the cables. When testing is performed later, the extrusion and clamping effect on the cables is released, and the structure acts as a guide and limiter to assist the cables to move through the bead chain assembly.

[0020] 4. The present invention tilts the baffle plate slightly upward near the delivery inlet, so that one end of the delivery inlet is opened larger, and the inner side shields both sides of the base through the baffle plate, and limits both sides of the bead chain assembly. When the cable is delivered along the delivery inlet, affected by the thickness of the cable, the front end of the guide plate slides along the slide groove, and the rear end drives the baffle plate and the insert strip to slide along the slide frame, opening one side of the base for the cable to enter. This way of delivering the cable can prevent the hazard of electric shock caused by accidental contact with the bead chain assembly.

[0021] 5. Compared with the prior art, the present invention, through the cooperation between the limit assembly and the base, the limit assembly can drive the base to move upward, and the cable is sent into the base and then pushed into the inside of the bead chain assembly. Since there is a certain height difference between the clamped arc plate and the base, there will be a certain interval between the bottom of the cable and the base. The excess length of the bead chain assembly enters the mutual grooves of the base, and the cables of different thicknesses are maintained in the middle position of the bead chain assembly, so that there is sufficient contact surface for voltage resistance testing, which is convenient for calibrating the horizontal position of the cable before testing the cables of different thicknesses, so as to improve the accuracy of the test.

The transmission belt 33 drives the bidirectional screw 22 to rotate and drive the connecting plate 24 to move in the opposite direction synchronously. The two arc blocks are close to limit the cables of different thicknesses. When in the extrusion and clamping state, they can move to both sides to clamp the cable. When testing is performed later, the extrusion and clamping effect of the cable is released, acting as a guiding and limiting structure to assist the cable to move through the bead chain assembly 4 (the mounting block 25 and the bidirectional screw 22 are installed on the spark machine body 1 through the plug rod 28 and the plug plate 21. The built-in spring can automatically pop out the plug plate 21 and the plug rod 28 after the transmission belt 33 is separated from the vertical column 23.

After the rotating plate 31 moves upward along the sliding rod 32, the protrusion 231 of the plug column separates from the slot 35, and then the rotating plate 31 is rotated ninety degrees to be misaligned with the bidirectional screw 22. After losing the plug-in limit, the plug plate 21 drives the bidirectional screw 22 and the arc plate 27 to move outward. At this time, the arc plate 27 is adjusted to a slightly clamping state, and the cable is straightened as the arc plate 27 moves.

Similarly, when the arc plate 27 is close to the outer surface of the protective shell 12, it is plugged with the vertical plate 56 (this plugging method is a common sliding plugging structure, not shown in the figure). After the arc plate 27 clamps the cable passing through both sides of the protective shell 12, it moves outward to straighten the cable.

Then, the two ends of the cable pass through the leak window 14, driving the two sets of bidirectional screws 22 to rotate, the arc plate 27 clamps the two ends of the cable, and drives the base 5 to rise, so that the cable is delivered into the bead chain assembly 4. After the rotating plate 31 moves upward along the slide rod 32, the protrusion 231 of the plug column is aligned with the slot 35 is separated, and then the rotating plate 31 is rotated ninety degrees to be misaligned with the bidirectional screw 22. After losing the plug-in limit, the plug plate 21 drives the bidirectional screw 22 and the arc plate 27 to move outward. At this time, the arc plate 27 is adjusted to a slightly clamped state. As the arc plate 27 moves, the cable is straightened. At this time, due to the height difference between the arc plate 27 and the base 5, the bottom of the cable is not in direct contact with the base 5. The cable enters the bead chain assembly 4, and the bottom of the bead chain assembly 4 moves along the arc groove of the base 5, wrapped around the bottom of the cable, releasing the squeezing and clamping effect on the cable, acting as a guiding and limiting structure, and the cable is pulled by one end to move through the bead chain assembly 4 for a voltage resistance test, and the test value is fed back to the display screen of the high-frequency spark machine.
