Description

Technical Field

[0001] This utility model relates to the field of welding wire spool testing technology, and in particular to a welding wire spool tensile testing device. Background Technology

[0002] A welding wire spool is a tool used to store and collect welding wire, playing an important role in the welding process. During the production of welding wire spools, tensile tests are conducted to ensure their quality. However, when positioning the welding wire spool, it is necessary to manually position it in multiple ways, which is quite troublesome. If the limit device is controlled by a power device to limit the welding wire spool, it will consume more energy. Utility Model Content

[0003] The main objective of this invention is to provide a welding wire spool tensile testing device, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A welding wire spool tensile testing device includes a support platform and a hydraulic rod. Guide rods are fixedly installed on the upper surface of the support platform near the four corners. A baffle is fixedly installed on the upper end of the guide rod. A hydraulic rod is fixedly installed on the upper surface of the baffle. A lifting plate is fixedly installed at the telescopic end of the hydraulic rod. A pressure rod is fixedly installed on the lower surface of the lifting plate near the four corners. Pull plates are fixedly installed on both sides of the lifting plate below the pressure rods. Clamping blocks are movably installed on the upper surface of the support platform near both sides. A welding wire spool is placed between the clamping blocks. A pressure plate is movably installed on the opposite side surface of the clamping blocks. A positioning wedge is movably installed on the rear surface of the pressure plate near both sides.

[0005] More preferably, a movable groove is provided on the upper surface and near the support platform, and knobs are movably installed on both sides of the support platform, with a double-headed screw fixedly installed between the knobs, passing through the movable groove.

[0006] More preferably, the front surface of the clamping block is provided with positioning grooves near both sides, and the number of positioning grooves is several. The front surface of the clamping block is provided with a rectangular track groove in the middle, and the front surface of the clamping block is provided with a threaded hole at the lower end.

[0007] More preferably, the rear surface of the pressure plate is fitted with a slider that is embedded in a rectangular track groove and can move back and forth, the rear surface of the pressure plate is provided with a storage groove near both sides, and the interior of the pressure plate is provided with a pressing groove in front of the storage groove.

[0008] More preferably, a rod is fixedly installed on the rear surface of the positioning wedge, penetrating the storage groove and the extrusion groove. A retaining ring is fixedly sleeved on the surface of the rod located inside the extrusion groove, and a spring is sleeved on the surface of the rod located inside the extrusion groove and behind the retaining ring.

[0009] In a further preferred embodiment, the double-headed screw passes through a threaded hole, the positioning wedge is embedded in a positioning wedge groove, and the guide rod passes through a lifting plate.

[0010] Compared with the prior art, this utility model proposes a welding wire spool tensile testing device, which has the following beneficial effects: In this invention, a support platform, hydraulic rod, lifting plate, clamping block, pressure rod, pull plate, pressure plate, and positioning wedge are arranged in a coordinated manner. By rotating a knob, the double-headed screw rotates, causing the two clamping blocks to move closer together, thus clamping welding wire reels of different diameters. Then, an external device activates the hydraulic rod, which pushes the lifting plate, pressure rod, and pull plate downwards. When the pull plate contacts the pressure plate, it pushes the pressure plate downwards until the pressure plate presses against the lower upper surface of the welding wire reel. At this point, because the positioning wedge is embedded in the positioning groove, the pressure plate cannot rise, thus completing the vertical positioning of the welding wire reel. When the limit is reached, the hydraulic rod controls the lifting plate and the pull plate to rise until the pull plate contacts the upper inner part of the welding wire spool. At this time, as the hydraulic rod continues to retract, the tensile strength test result of the welding wire spool can be tested using the pressure sensor installed on the upper surface of the pull plate. When the limit of the pressure plate on the welding wire spool is released, pull the pressure plate forward to make the positioning wedge block exit from the positioning wedge groove. Then move the pressure plate up. Finally, rotate the knob in the opposite direction to make the two clamping blocks move away from each other. In the above way, not only can the welding wire spool be limited in many ways, but the hydraulic rod can also control the descent of the pressure plate and position the welding wire spool.

[0013] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0014] It should be noted that all directional indicators such as up, down, left, right, front, back, etc. in the embodiments of this utility model are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indicator will also change accordingly.

[0015] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can refer to a fixed connection, a detachable connection, or an integral part; it can also refer to a mechanical connection, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0016] like Figure 1-4 As shown, a welding wire spool tensile testing device includes a support platform 1 and a hydraulic rod 4. Guide rods 2 are fixedly installed on the upper surface of the support platform 1 near the four corners. A baffle 3 is fixedly installed on the upper end of the guide rod 2. A hydraulic rod 4 is fixedly installed on the upper surface of the baffle 3. A lifting plate 5 is fixedly installed at the telescopic end of the hydraulic rod 4. A pressure rod 8 is fixedly installed on the lower surface of the lifting plate 5 near the four corners. Pull plates 9 are fixedly installed on both sides of the lifting plate 5 below the pressure rod 8. Clamping blocks 7 are movably installed on the upper surface of the support platform 1 near both sides. A welding wire spool 6 is placed between the clamping blocks 7. A pressure plate 10 is movably installed on the opposite side surface of the clamping blocks 7. A positioning inclined block 11 is movably installed on the rear surface of the pressure plate 10 near both sides.

[0017] In a preferred embodiment: a movable groove 102 is provided on the upper surface of the support platform 1 and close to it; knobs 101 are movably installed on both sides of the support platform 1; and a double-headed screw 103 that passes through the movable groove 102 is fixedly installed between the knobs 101.

[0018] In the above structure, the double-headed screw 103 can be rotated by manually rotating the knob 101, thereby controlling the two clamping blocks 7 to move closer or further apart.

[0019] In a preferred embodiment: the front surface of the clamping block 7 is provided with positioning grooves 701 near both sides, and the number of positioning grooves 701 is several; the front surface of the clamping block 7 is provided with a rectangular track groove 703 in the middle; and the front surface of the clamping block 7 is provided with a threaded hole 702 at the lower end.

[0020] In the above structure, when the positioning inclined block 11 is embedded in the positioning inclined groove 701, the pressure plate 10 cannot move up, but can only move down and make the positioning inclined block 11 embedded in another positioning inclined groove 701.

[0021] In a preferred embodiment: a slider 1001 is installed on the rear surface of the pressure plate 10 and is embedded in the rectangular track groove 703 and can move back and forth; a storage groove 1002 is provided on the rear surface of the pressure plate 10 near both sides; and a pressing groove 1003 is provided inside the pressure plate 10 and in front of the storage groove 1002.

[0022] In the above structure, when the pressure plate 10 is pressed down, the positioning wedge 11 will exit from the positioning wedge groove 701 and move into the receiving groove 1002. During this process, the spring 1103 will be compressed until the positioning wedge 11 is embedded in another positioning wedge groove 701. At this time, the spring 1103 will extend again. When the pressure plate 10 is pulled forward, the slider 1001 will always be embedded in the rectangular track groove 703, and the distance between the rear surface of the pressure plate 10 and the clamping block 7 will increase until the positioning wedge 11 exits from the positioning wedge groove 703. There is a certain friction between the slider 1001 and the pressure plate 10, and the coefficient of friction must ensure that when the pressure plate 10 is pressed down, the pressure plate 10 will not produce a gap between the pressure plate 10 and the clamping block 7 due to the positioning wedge 11 exiting from the positioning wedge groove 703.

[0023] In a preferred embodiment: a rod 1101 that penetrates the storage groove 1002 and the extrusion groove 1003 is fixedly installed on the rear surface of the positioning wedge 11. A retaining ring 1102 is fixedly sleeved on the surface of the rod 1101 located inside the extrusion groove 1003. A spring 1103 is sleeved on the surface of the rod 1101 located inside the extrusion groove 1003 and behind the retaining ring 1102.

[0024] In a preferred embodiment: the double-ended screw 103 passes through the threaded hole 702, the positioning wedge 11 is embedded in the positioning wedge groove 701, and the guide rod 2 passes through the lifting plate 5.

[0025] In use, rotating the knob 101 causes the double-headed screw 103 to rotate, bringing the two clamping blocks 7 closer together to hold the welding wire reels 6 of different diameters. Then, an external device activates the hydraulic rod 4, which pushes the lifting plate 5, pressure rod 8, and pull plate 9 downwards. When the pull plate 9 contacts the pressure plate 10 and pushes it downwards until it presses against the lower upper surface of the welding wire reel 6, the pressure plate 10 cannot rise because the positioning inclined block 11 is embedded in the positioning inclined groove 701, thus completing the welding process. When the upper and lower positions of the wire spool 6 are limited, the hydraulic rod 4 controls the lifting plate 5 and the pull plate 9 to rise until the pull plate 9 contacts the upper inner end of the wire spool 6. At this time, as the hydraulic rod 4 continues to retract, the tensile test result of the wire spool 6 can be tested using the pressure sensor installed on the upper surface of the pull plate 9. When the pressure plate 10 is released from limiting the wire spool 6, the pressure plate 10 is pulled forward to make the positioning inclined block 11 exit from the positioning inclined groove 701. Then the pressure plate 10 is moved up. Finally, the knob 101 is rotated in the opposite direction to make the two clamping blocks 7 move away from each other.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
