Description

Technical Field

[0001] The present application relates to the technical field of welding machines, and in particular, to a method for measuring and adjusting a welding carriage. Background Art

[0002] The narrow lap resistance welding machine includes a welding trolley, on which a welding wheel and a shearing blade are arranged, so that the accuracy of the welding trolley affects the accuracy of the welding wheel and the shearing blade. In order to obtain a qualified weld, the accuracy of the welding trolley needs to be maintained.

[0003] At present, the gap between the eccentric side guide wheel and the side of the track is mainly adjusted to keep the gap between the eccentric side guide wheel and the side of the track at a preset gap to maintain the accuracy of the welding trolley. There are usually two methods for adjusting the gap between the eccentric side guide wheel and the side of the track. The first method is to adjust the gap between the eccentric side guide wheel and the side of the track first, and then use a feeler gauge to measure. According to the measurement result, determine whether to continue adjusting. During the actual measurement, the operator's arm passes through the manhole and extends the feeler gauge to the vicinity of the gap between the eccentric side guide wheel and the side of the track. Because the operator's arm blocks the manhole, it is difficult for the operator to observe the gap between the eccentric side guide wheel and the side of the track, and it is not easy to accurately position the feeler gauge to the gap between the eccentric side guide wheel and the side of the track. , the operability is poor. The second is to adjust the eccentric side guide wheel to a position close to the side of the track, and then slowly adjust the eccentric side guide wheel to a state of just light transmission. At this time, the gap between the eccentric side guide wheel and the side of the track is 0.03-0.05mm, but just light transmission is the subjective feeling of the operator and there may be errors. In particular, the eccentric side guide wheel needs to be replaced frequently. After multiple adjustments, large accumulated errors may occur, affecting the centering of the welding wheel and the weld, the morphology of the strip shear fracture and the straightness of the welding trolley, and even making the welding trolley's travel route S-shaped. In addition, the accumulated errors are gradually generated as the production progresses, which are difficult to detect in time, and ultimately make the weld unqualified or even cause the weld to break.

[0047] Figure 1 A flow chart of a welding carriage measurement method in an embodiment of the present application is shown. Figure 2 FIG. 4 shows a schematic diagram of measuring a first distance in an embodiment of the present application. Figure 3 FIG. 4 shows a schematic diagram of measuring the second distance in an embodiment of the present application. Figure 2 and Figure 3 In the figure, 1 is the entrance clamp, 2 is the upper welding wheel, 3 is the lower welding wheel, 4 is the exit clamp, 5 is the first distance, 6 is the upper shear blade, 7 is the lower shear blade, and 8 is the second distance. Figures 1 to 3 , provides a welding carriage measurement method, which is applied to narrow lap resistance welding machines, including at least S1 to S2, as detailed below:

[0048] In step S1, the entrance clamp and the exit clamp are moved to the welding position, and the exit clamp is swung to the middle position, wherein the entrance clamp and the exit clamp are arranged relative to each other. The welding position refers to the position of the entrance clamp and the exit clamp when welding the steel strip. When the entrance clamp and the exit clamp are in the welding position, a first gap is formed between the entrance clamp and the exit clamp, and the welding carriage can pass through the first gap. When welding the steel strip, the entrance clamp drives the head of the entrance steel strip to move toward the exit clamp to the welding position, and the exit clamp drives the tail of the exit steel strip to move toward the entrance clamp to the welding position, and then the tail of the exit steel strip is overlapped on the head of the entrance steel strip, and then welding is performed. Swinging the exit clamp to the middle position means swinging the exit clamp to a position where the opening direction is parallel to the steel strip.

[0049] In step S2, the welding carriage is moved to at least two first measuring positions between the entrance clamp and the exit clamp, and a first distance between the end face of the lower welding wheel and the end face of the exit clamp is measured at each of the first measuring positions, wherein the lower welding wheel is arranged on the welding carriage, and when the welding carriage is at the first measuring position, the end face of the lower welding wheel and the end face of the exit clamp are relatively distributed, that is, Figure 2 The right end surface of the lower welding wheel and the left end surface of the outlet clamp are relatively distributed.

[0050] In some embodiments, if the exit clamp is a lap platform, the first distance is the distance between the entry clamp and the lower welding wheel.

[0051] In some embodiments, moving the welding carriage to at least two first measurement positions between the entrance clamp and the exit clamp includes: moving the welding carriage to a first target position, wherein the first target position is any position where the lower welding wheel is located between the entrance clamp and the exit clamp when the entrance clamp and the exit clamp are in the welding position; selecting at least two first measurement positions in the first target positions, and moving the welding carriage to each of the first measurement positions respectively.

[0052] In some embodiments, the first measuring position may be a position where the lower welding wheel is located between the inlet clamp and the outlet clamp and the edge of the lower welding wheel and the working side edge of the outlet clamp in the width direction of the strip are flush, that is, Figure 2 The position where the rear edge of the outlet clamp is flush with the rear edge of the lower welding wheel may also be the position where the lower welding wheel is located between the inlet clamp and the outlet clamp and the edge of the lower welding wheel in the strip width direction is flush with the edge of the driving side of the outlet clamp, that is, Figure 2 The front edge of the outlet clamp is flush with the front edge of the lower welding wheel.

[0053] In some embodiments, the step of moving the inlet clamp and the outlet clamp to the welding position includes: determining a first position corresponding to the inlet clamp and a second position corresponding to the outlet clamp according to the welding position; moving the inlet clamp to the first position, and moving the outlet clamp to the second position. The first position is the position of the inlet clamp when welding steel strips, and the second position is the position of the outlet clamp when welding steel strips.

[0054] In some embodiments, when measuring the first distance, the lower end surface of the upper welding wheel is moved to a position contacting the upper end surface of the lower welding wheel.

[0055] In some embodiments, the method further includes: moving the inlet clamp and the outlet clamp to a shearing position, and swinging the outlet clamp to a middle position; lifting the lower shear blade to a highest position, wherein the lower shear blade and the outlet clamp are arranged relative to each other; moving the welding carriage to at least two second measuring positions between the inlet clamp and the outlet clamp, and measuring a second distance between the lower shear blade and an end face of the outlet clamp at each second measuring position, wherein the lower shear blade is arranged on the welding carriage, and when the welding carriage is in the second measuring position, the end face of the lower shear blade and the end face of the outlet clamp are arranged relative to each other, that is, Figure 2 The right end face of the lower shear blade and the left end face of the outlet clamp are arranged relatively. Swinging the outlet clamp to the middle position means swinging the outlet clamp to a position where the opening direction is parallel to the strip.

[0056] In some embodiments, moving the welding carriage to at least two second measurement positions between the entrance clamp and the exit clamp includes: moving the welding carriage to a second target position, wherein the second target position is any position where the lower shear blade is located between the entrance clamp and the exit clamp when the entrance clamp and the exit clamp are in the shearing position; selecting at least two second measurement positions in the second target positions, and moving the welding carriage to each of the second measurement positions respectively.

[0057] In some embodiments, the second measuring position may be a position where the lower shear blade is located between the inlet clamp and the outlet clamp and the edge of the lower shear blade close to the outlet clamp in the width direction of the strip is flush with the working side edge of the outlet clamp, that is, Figure 3 The position where the rear edge of the outlet clamp is flush with the rear edge of the lower shear blade on the right side can also be the position where the lower shear blade is located between the inlet clamp and the outlet clamp and the lower shear blade edge close to the outlet clamp in the strip width direction is flush with the driving side edge of the outlet clamp, that is, Figure 3The front edge of the outlet clamp in the middle is flush with the front edge of the lower shear blade on the right side.

[0058] In some embodiments, the step of moving the inlet clamp and the outlet clamp to the shearing position includes: determining a third position corresponding to the inlet clamp and a fourth position corresponding to the outlet clamp according to the shearing position; moving the inlet clamp to the third position, and moving the outlet clamp to the fourth position. The third position refers to the position of the inlet clamp when shearing the strip, and the fourth position refers to the position of the outlet strip when shearing the strip.

[0059] In some embodiments, the distance between the outlet clamp and the inlet clamp when they are in the welding position is smaller than the distance between the outlet clamp and the inlet clamp when they are in the shearing position.

[0060] In some embodiments, when the shearing blade of the welding trolley is a double shearing blade, the second distance is the distance between the lower shearing blade end face close to the outlet clamp and the outlet clamp end face, wherein the double shearing blade includes two shearing blade groups, each shearing blade group includes an upper shearing blade and a lower shearing blade.

[0061] In some embodiments, the first distance and the second distance are measured using a vernier caliper.

[0062] In some embodiments, if the outlet clamp is a lap platform, the second distance is the distance between the inlet clamp and the lower shear blade.

[0063] It should be noted that the present application is applicable to the case where the entrance clamp is a overlapping platform. When the entrance clamp is a overlapping platform, the overlapping amounts on the working side and the transmission side are inconsistent. Therefore, the first distance and the second distance are measured based on the exit clamp.

[0064] According to a second aspect of the present application, a welding trolley adjustment method is provided, comprising: obtaining the first distance according to a welding trolley measurement method described in any embodiment of the first aspect of the present application; comparing the first distance with a first preset distance, and adjusting the distance between the side guide wheel and the track according to the comparison result. The first preset distance is the distance between the lower welding wheel and the exit clamp when the exit clamp is in the welding position and the distance between the side guide wheel and the track is the set distance. The greater the difference between the first distance and the first preset distance, the worse the accuracy of the welding trolley.

[0065] In some embodiments, the first distance is compared with the first preset distance, and the distance between the side guide wheel and the track is adjusted according to the comparison result, including: if the first distance is greater than the first preset distance, reducing the distance between the side guide wheel and the track; if the first distance is equal to the first preset distance, keeping the distance between the side guide wheel and the track unchanged; if the first distance is less than the first preset distance, increasing the distance between the side guide wheel and the track.

[0066] In some embodiments, the method comprises: obtaining the second distance according to the welding carriage measurement method according to the first aspect of the present application; comparing the second distance with a second preset distance, and adjusting the distance between the side guide wheel and the track according to the comparison result. The second preset distance is the distance between the lower shear blade and the exit clamp when the exit clamp is in the shearing position and the distance between the side guide wheel and the track reaches the set distance.

[0067] In some embodiments, the comparing the second distance with the second preset distance and adjusting the distance between the side guide wheel and the track according to the comparison result includes: if the second distance is greater than the second preset distance, reducing the distance between the side guide wheel and the track; if the second distance is equal to the second preset distance, keeping the distance between the side guide wheel and the track unchanged; if the second distance is less than the second preset distance, increasing the distance between the side guide wheel and the track. The greater the difference between the second distance and the second preset distance, the worse the accuracy of the welding carriage.

[0068] In some embodiments, a first adjustment position of the side guide wheel is determined according to the first measurement position, and when the first distance is greater than or less than the first preset distance, the side guide wheel at the first adjustment position is adjusted.

[0069] In some embodiments, determining the first adjustment position of the side guide wheel based on the first measurement position includes: acquiring a first target distance between the first measurement position and the side guide wheel; and taking the position of the side guide wheel with the smallest first target distance as the first adjustment position.

[0071] In some embodiments, when the first distance is equal to the first preset distance, the side guide wheel at the first adjustment position is not adjusted.

[0072] In some embodiments, the welding carriage has two side guide wheels in the length direction of the strip and the side guide wheels on the same side are distributed along the width direction of the strip, the first measuring position is the position when the lower welding wheel is located between the entrance clamp and the exit clamp and the edge of the lower welding wheel and the working side edge of the exit clamp in the width direction of the strip are flush, and the first adjustment position is the position of the side guide wheel located at the rear side close to the exit clamp in the width direction of the strip.

[0073] In some embodiments, the welding carriage has two side guide wheels in the length direction of the strip and the side guide wheels on the same side are distributed along the width direction of the strip. The first measuring position is the position when the lower welding wheel is located between the entrance clamp and the exit clamp and the edge of the lower welding wheel and the transmission side edge of the exit clamp in the width direction of the strip are flush. The first adjustment position is the position of the side guide wheel located in front of the side close to the exit clamp in the width direction of the strip.

[0074] In some embodiments, a second adjustment position of the side guide wheel is determined according to the second measurement position, and when the second distance is greater than or less than the second preset distance, the side guide wheel at the second adjustment position is adjusted.

[0075] In some embodiments, determining the second adjustment position of the side guide wheel based on the second measurement position includes: acquiring a second target distance between the second measurement position and the side guide wheel; and taking the position of the side guide wheel with the smallest second target distance as the second adjustment position.

[0076] In some embodiments, when the second distance is greater than or less than the second preset distance, the side guide wheels at the second adjustment position are adjusted, including: when the second distance is greater than the second preset distance, the side guide wheels at the second adjustment position are adjusted to reduce the gap between the side guide wheels at the second adjustment position and the track; when the second distance is less than the second preset distance, the side guide wheels at the second adjustment position are adjusted to increase the gap between the side guide wheels at the second adjustment position and the track.

[0077] In some embodiments, when the second distance is equal to the second preset distance, the side guide wheel at the second adjustment position is not adjusted.

[0078] In some embodiments, the welding carriage has two side guide wheels in the length direction of the strip and the side guide wheels on the same side are distributed in the width direction of the strip. The second measuring position is the position when the lower shear blade is located between the inlet clamp and the outlet clamp and the edge of the lower shear blade close to the outlet clamp in the width direction of the strip is flush with the working side edge of the outlet clamp. The second adjustment position is the position of the side guide wheel located at the rear side close to the outlet clamp in the width direction of the strip. Figure 2 and Figure 3 The front and rear direction of the strip is Figure 2 and Figure 3 left and right direction.

[0079] In some embodiments, the welding carriage has two side guide wheels in the length direction of the strip and the side guide wheels on the same side are distributed along the width direction of the strip, the second measuring position is the position when the lower shear blade is located between the entrance clamp and the exit clamp and the edge of the lower shear blade close to the exit clamp in the width direction of the strip is flush with the transmission side edge of the exit clamp, and the second adjustment position is the position of the side guide wheel located in front of the side close to the exit clamp in the width direction of the strip.

[0080] In the present application, on the one hand, by measuring the first distance, the running accuracy of the welding trolley, that is, the accuracy of the welding wheel during welding, can be measured. By measuring the second distance, the straightness of the fracture when shearing the strip can be measured, thereby indirectly detecting the quality of the lap fracture of the strip. On the other hand, the side guide wheel and the exit clamp are connected, and the center of the welding trolley is used as the base point. The first distance and the second distance will magnify the error between the side guide wheel and the track by about 4 times, making it easier to observe and adjust the installation deviation of the side guide wheel, thereby better ensuring the accuracy of the welding trolley.
