Description

Technical Field

[0001] The utility model belongs to the technical field of detection devices, and particularly relates to a welding point detection device. Background Art

[0002] The welding spot detection device is the most important tooling component for controlling the quality of steel cords. Its function is to weld two steel cords of the same specification and model, ensure the quality and wire diameter requirements of the welding spot at the welding point, meet the passing performance of the wire plate during customer use, obtain more ideal performance, and improve the quality of steel cords. The existing welding spot detection device uses a straight-bar welding spot detection device. According to the specifications of the steel cord, the corresponding welding spot detection device is selected for testing.

[0003] Different types of welding spot detection devices are used to detect different types of steel cords. Each type of steel cord corresponds to a welding spot detection device. Due to structural design defects, the built-in detection strip of the long strip welding spot detection device is a linear structure. The linear structure is determined according to the corresponding specifications of the steel cord model. The linear structure causes that only the left and right sides of the steel cord welding spot can be detected during the welding spot detection process, and 360° circumferential detection cannot be performed, resulting in the risk of missing the upper and lower sides. The site requires operators to perform circumferential detection more than 3 times when detecting welding spots to ensure that the welding spot quality is detected in the circumferential direction of the steel cord. The welding spot quality directly affects whether the customer will have quality risks and customer complaints during production. However, in the actual detection process, even if the operator performs more than 3 circumferential detections, there will still be defective products that pass the detection, and the existing detection device has the risk of missing detection. Summary of the invention

[0004] In view of the above-mentioned deficiencies in the prior art, the utility model provides a welding spot detection device using 360° circular detection to solve the above-mentioned problems.

[0005] The utility model provides a welding spot detection device, comprising a fixing frame, a lower base plate is arranged at the top of the fixing frame, an upper top plate is arranged above the lower base plate, a plurality of first positioning pins are arranged at the bottom of the upper top plate, a first pin hole corresponding to the first positioning pins is arranged at the top of the lower base plate, a first locking portion is arranged between the lower base plate and the upper top plate, and a plurality of matching semicircular grooves are respectively arranged on the lower base plate and the upper top plate.

[0006] Furthermore, the first locking portion includes a locking screw, one end of which passes through the upper top plate and is screwed to the lower bottom plate, and an adjustment handle is provided on the top of the locking screw.

[0007] Furthermore, a spreading spring is sleeved on the locking screw, two ends of the spreading spring abut against the upper top plate and the lower bottom plate respectively, and a spring groove cooperating with the spreading spring is opened on the top of the lower bottom plate.

[0016] It should be noted that the directions "front, back, left, right, up, down" mentioned in the text are all based on Figure 1 The directions of “front, back, left, right, up, and down” are used as the basis.

[0017] See also Figure 1 and Figure 2The utility model is a welding spot detection device, comprising a fixing frame 1 connected to a welding machine, a lower base plate 2 is arranged at the top of the fixing frame 1, an upper top plate 3 is arranged above the lower base plate 2, a plurality of first positioning pins 4 are arranged at the bottom of the upper top plate 3, a first pin hole 5 corresponding to the first positioning pin 4 is arranged at the top of the lower base plate 2, and the first positioning pin 4 is slidably connected with the first pin hole 5; a first locking portion is arranged between the lower base plate 2 and the upper top plate 3, and the first locking portion is used to align and lock the lower base plate 2 and the upper top plate 3 up and down; a plurality of matching semicircular grooves 6 are respectively arranged on the lower base plate 2 and the upper top plate 3, and when the lower base plate 2 is aligned with the upper top plate 3, the upper and lower corresponding semicircular grooves 6 form a detection hole, and the sizes of the left and right adjacent semicircular grooves 6 are different, and the sizes are determined according to the steel cords commonly detected.

[0018] In the preferred technical solution of this embodiment, the first locking part includes a locking screw 7, one end of which passes through the upper top plate 3 and is screwed to the lower bottom plate 2, and an adjustment handle 8 is provided on the top of the locking screw 7. By holding the adjustment handle 8 and applying force to tighten the locking screw 7, the upper top plate 3 and the lower bottom plate 2 can be aligned and locked.

[0019] The preferred technical solution in this embodiment is that in order to facilitate opening the lower bottom plate 2 and the upper top plate 3, a spreading spring 9 is sleeved on the locking screw 7, and the two ends of the spreading spring 9 abut against the upper top plate 3 and the lower bottom plate 2 respectively, and a spring groove 10 is opened on the top of the lower bottom plate 2 to cooperate with the spreading spring 9. When the upper top plate 3 and the lower bottom plate 2 are aligned and locked by tightening the locking bolt, the compressed spreading spring 9 is received in the spring groove 10; when the locking bolt is rotated in the opposite direction, the spreading spring 9 spreads the upper top plate 3 and the lower bottom plate 2 apart by elastic force.

[0020] The preferred technical solution in this embodiment is that, considering that the semicircular groove 6 will be worn after long-term detection, and the detection accuracy will be lost due to continuous wear, the semicircular groove 6 is separated from the lower bottom plate 2 and the upper top plate 3, and is designed as a detachable and replaceable replacement part structure, as shown in the following figure. Figure 1 and Figure 2 As shown in the figure, a mounting groove 11 is provided on the upper top plate 3 and the lower bottom plate 2, and a plurality of second positioning pins 12 are provided in each of the mounting grooves 11. A detection plate 13 is provided in each of the mounting grooves 11, and a second pin hole 14 corresponding to the second positioning pins 12 is provided on the detection plate 13, and the second positioning pins 12 are slidably connected with the second pin holes 14, and the semicircular groove 6 is provided on the detection plate 13; a second locking portion is provided between each of the mounting grooves 11 and the detection plate 13, and the second locking portion is used to fix the detection plate 13 in the mounting groove 11.

[0021] The preferred technical solution in this embodiment is as follows Figure 2 As shown in the figure, the second locking portion includes a locking screw 15, a countersunk hole 16 is provided on the detection plate 13, and a locking screw hole 17 corresponding to the countersunk hole 16 is opened in the mounting groove 11. The locking screw 15 passes through the countersunk hole 16 and is screwed to the locking screw hole 17.

[0022] The preferred technical solution in this embodiment takes into account the different diameters of the steel cords to be tested. In order to enable the operator to quickly identify the aperture of the test hole, one side of each semicircular groove 6 is laser-marked with a corresponding number for identifying the aperture of the semicircular groove 6.

[0023] The use and principle of the utility model: when the first locking part aligns and locks the upper top plate 3 and the lower bottom plate 2, the semicircular grooves 6 aligned up and down form detection holes of different apertures. After the steel cord passes through the detection hole, the welding point is tested for 360° in the circumference. The test result can be obtained according to the passability of the steel cord welding point, and no re-testing is required. When the semicircular grooves 6 on the upper top plate 3 and the lower bottom plate 2 are worn out due to too many tests, a new detection plate 13 can be replaced to ensure its detection accuracy.
