Description

Technical Field

[0001] The utility model relates to the field of continuous rolling of a rolling mill in a steel bar and wire rolling workshop, and in particular to a welding robot capable of automatically welding a rolling mill base. Background Art

[0002] In the bar and wire workshop of steel enterprises, the rolling mill is an indispensable and important equipment in the rolling process and plays a vital role in metal processing. In actual production adjustments, due to the influence of rolling mill replacement, there is sliding friction between the rolling mill and the rolling mill base, and the rolling mill base will be worn to varying degrees. Manual maintenance has the defects of high cost and low efficiency. Utility Model Content

[0003] The utility model aims to use a welding robot capable of automatically welding a rolling mill base to replace manual welding repair, thereby improving maintenance efficiency and reducing maintenance costs.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is:

[0005] A welding robot capable of automatically welding a rolling mill base comprises two transversely parallel sleeper rails, a sliding base, a guide rail and a welding trolley, wherein the welding trolley is slidably arranged on the guide rails, and the guide rails are detachably mounted on the sliding base, that is, a certain distance is maintained between the guide rails and the sliding base, and both ends of the sliding base are respectively slidably mounted on the sleeper rails on the corresponding sides.

[0006] Furthermore, both sleeper rails are laterally provided with track grooves, and sliders are installed at both ends of the lower side of the sliding base. The sliders can slide back and forth in the track grooves along the length direction of the sleeper rails. The sliding of the sliders can drive the sliding base and the welding trolley on the sliding base to move laterally.

[0007] Furthermore, the slider is connected to the sliding base through a connecting rod, and the upper end of the connecting rod passes through the through hole of the sliding base from the back side of the sliding base. By setting the connecting rod, the slider can be fixed to the lower side of the sliding base; wherein, at least the upper and middle part of the connecting rod can be set as an external thread section with an external thread, and the through hole is provided with an internal thread matching the external thread section, so that the upper end of the connecting rod with the external thread section passes through the through hole with the internal thread and is fixed by a nut.

[0008] Furthermore, the cross-section of the track groove is an inverted T-shape, and the lower part of the connecting rod and the slider are both located in the inverted T-shaped track groove. The setting of the inverted T-shaped track groove has a limiting guiding effect on the slider and the connecting rod, that is, guiding the slider to move along the setting direction of the inverted T-shaped track groove on the sleeper rail.

[0009] Furthermore, a plurality of adjusting bolts are provided on the sliding base near the connecting rod. Specifically, there are four adjusting bolts, that is, an adjusting bolt is respectively provided at the four corners of the sliding base with the through hole as the diagonal center point. Each adjusting bolt can abut against the sleeper rail after passing through the corresponding bolt hole on the sliding base, and then after the sliding base is adjusted laterally, the sliding base is fixed on the sleeper rail.

[0010] Furthermore, the guide rail is fixedly mounted on the sliding base by a first fixed magnet, and the guide rail and the rectangular sliding base are arranged in the same direction along the length direction. The width of the sliding base is much larger than the width of the guide rail to ensure the stability of the welding trolley moving on the guide rail.

[0011] Furthermore, a rack is provided on one side of the guide rail, and the welding carriage includes a gear meshing with the rack at its bottom, the gear is connected to a driving motor provided on the welding carriage through a mounting shaft, and the driving motor drives the gear to rotate on the rack, thereby driving the welding carriage to reciprocate on the guide rail. That is, the welding carriage can automatically reciprocate on the guide rail.

[0012] Furthermore, the sleeper rails are connected to the object to be welded via the second fixed magnet. The second fixed magnet is provided with a slot into which the sleeper rail can be inserted, and the provision of the slot can increase the contact area between the sleeper rail and the second fixed magnet, thereby improving the fixing effect of the second fixed magnet on the sleeper rail.

[0013] The beneficial effect of this utility model patent is: using a welding robot that can automatically weld the rolling mill base ( Figure 1 ) replaces manual welding, which can effectively improve the welding quality of the rolling mill base. The repair time of each rolling mill base is shortened from 24 hours to 8 hours, and the number of welding personnel can be reduced by 2, which greatly improves the maintenance efficiency of the rolling mill base and reduces the maintenance cost.

[0022] The present invention will be further described below in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0023] like Figure 1-Figure 7 As shown, a welding robot capable of automatically welding a rolling mill base comprises two transversely parallel sleeper rails 6, a sliding base 5, a guide rail 1 and a welding trolley 2. The welding trolley 2 is slidably arranged on the guide rail 1, and the guide rail 1 is detachably mounted on the sliding base 5, that is, a certain distance is maintained between the guide rail 1 and the sliding base 5 to prevent the sliding base 5 from affecting the movement of the welding trolley 2. Both ends of the sliding base 5 are slidably mounted on the sleeper rails 6 on the corresponding side. After adjusting the lateral position of the sliding base 5 on the sleeper rail 6, the welding trolley 2 runs on the guide rail 1, and by adjusting the welding parameters of the control panel of the welding trolley 2, the welding trolley 2 can perform uninterrupted reciprocating welding.

[0024] like Figure 6 and Figure 7 As shown, a rack 3 is provided on one side of the guide rail 1, and the welding carriage 2 includes a gear meshing with the rack 3 provided at the bottom thereof, and the gear is connected to a driving motor provided on the welding carriage 2 through a mounting shaft, and the driving motor drives the gear to rotate on the rack 3, thereby driving the welding carriage 2 to reciprocate on the guide rail 1. That is, the welding carriage 2 can automatically move longitudinally on the guide rail 1, thereby performing a reciprocating welding operation uninterruptedly.

[0025] The matching parts of welding carriage 2 and guide rail 1 are purchased directly from the manufacturer. After welding carriage 2 is powered on, it moves linearly on guide rail 1, driving the welding gun to complete linear continuous welding. The welding parameters can be adjusted according to the control panel on welding carriage 2. The control panel of welding carriage 2 mainly adjusts the welding data: walking speed, welding swing, swing speed, left stop time, right stop time, left and right compensation. There is a welding arm on the right side of welding carriage 2, which is used to fix the welding clamp. The tightening screw can be adjusted to adjust the tightness of the welding arm.

[0026] like Figure 1As shown, track grooves 10 are transversely provided on the two sleeper rails 6, and sliders 7 are installed at both ends of the lower side of the sliding base 5. The sliders 7 can slide back and forth in the track grooves 10 along the length direction of the sleeper rails 6; the sliding of the sliders 7 can drive the sliding base 5 and the welding trolley 2 on the sliding base 5 to move transversely.

[0027] The device manually pushes the sliding base 5 to move the slider 7 in the track groove 10, which can then drive the welding trolley 2 on the sliding base 5 to move horizontally. The reason why manual pushing is considered instead of setting an electric pushing structure is mainly because, during use, the lateral movement adjustment range of the welding trolley 2 is not very large, and only fine-tuning is required. Therefore, considering unnecessary waste and making the welding robot simple and practical, the electric pushing sliding base 5 structure is not set.

[0028] like Figure 4 As shown, the slider 7 is connected to the sliding base 5 through a connecting rod 8, and the upper end of the connecting rod 8 passes through the through hole of the sliding base 5 from the back side of the sliding base 5. By setting the connecting rod 8, the slider 7 can be fixed to the lower side of the sliding base 5; wherein at least the middle and upper part of the connecting rod 8 is set as an external thread section, and the through hole is provided with an internal thread matching the external thread section, so that the upper end of the connecting rod 8 with the external thread section passes through the through hole with the internal thread and is fixed by a nut.

[0029] like Figure 3 and Figure 5 As shown, the cross section of the track groove 10 is an inverted T-shaped, and the lower part of the connecting rod 8 and the slider 7 are both located in the inverted T-shaped track groove 10. The setting of the inverted T-shaped track groove 10 has a limited guiding effect on the slider 7 and the connecting rod 8, that is, it guides the slider 7 to move along the direction of the inverted T-shaped track groove 10 on the sleeper rail 6. The two sleeper rails 6 are placed in parallel with both ends aligned to ensure that the slider 7 connected to the sliding base 5 through the connecting rod 8 slides smoothly in the inverted T-shaped track groove 10 of the sleeper rail 6.

[0030] like Figure 2 As shown, a plurality of adjusting bolts 9 are provided on the sliding base 5 near the connecting rod 8. Specifically, there are four adjusting bolts 9, that is, an adjusting bolt 9 is respectively provided at the four corners of the sliding base 5 with the through hole as the diagonal center point. Each adjusting bolt 9 can be abutted against the sleeper rail 6 after passing through the corresponding bolt hole on the sliding base 5, and then after the sliding base 5 is adjusted laterally, the sliding base 5 is fixed on the sleeper rail 6.

[0031] like Figure 6As shown, the guide rail 1 is fixedly mounted on the sliding base 5 through the first fixed magnet 4. The installation direction of the guide rail 1 is parallel to the direction of the weld. A plurality of first fixed magnets 4 can be provided according to the installation requirements. By providing the first fixed magnet 4, the disassembly and assembly of the guide rail 1 can be facilitated. The guide rail 1 and the rectangular sliding base 5 are arranged in the same direction along the length direction. The width of the sliding base 5 is much larger than the width of the guide rail 1 (at least 4 times larger than the width of the guide rail 1) to ensure the stability of the welding trolley 2 moving on the guide rail 1. The sleeper rails 6 are connected to the objects to be welded through the second fixed magnets 11. A plurality of second fixed magnets 11 are provided. Generally, a second fixed magnet 11 is installed at the bottom of both ends of each sleeper rail 6.

[0032] Due to the unevenness and narrow space of the welding mill base, it is not suitable for welding robots with mobile working platforms (such as welding robots with platform bases installed under the two sleeper rails 6 and the sliding base 5) to perform operations. However, the present application is suitable for welding sites with small and uneven spaces through the design of two sleeper rails 6, sliders 7, connecting rods 8, adjusting bolts 9, and inverted T-shaped track grooves 10. It is easy to install, highly practical, and the entire equipment is low in price.

[0033] Example 2

[0034] The difference between this embodiment and the first embodiment is that the guide rail 1 and the first fixed magnet 4 are re-fixed by fastening bolts, and the provision of the fastening bolts can play a positioning role for the guide rail 1. The second fixed magnet 11 is provided with a slot into which the sleeper rail 6 can be inserted, and the provision of the slot can increase the contact area between the sleeper rail 6 and the second fixed magnet 11, thereby improving the fixing effect of the second fixed magnet 11 on the sleeper rail 6.

[0035] The above are only preferred implementations of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
