Description

Technical Field

[0001] The invention relates to the technical field of roll welding machines, in particular to a roll welding machine used for welding shelf plates. Background Art

[0002] Roll welding machine is a special welding equipment dedicated to the roll welding process. Roll welding is also called girth welding. It uses a pair of roller electrodes instead of the cylindrical electrodes of spot welding, and moves the workpiece to be welded between the rollers to produce a sealed weld with overlapping molten cores, thereby welding the workpieces together.

[0003] In the production process of shelves, in order to reduce the use of materials while ensuring effective protection of the items on the shelves, mesh plates or wire mesh are generally welded between two adjacent columns of the shelves as side baffles. Since the thickness of the shelf plates is mostly less than 2mm, the plate thickness is thin, and the welding of argon arc welding, double arc welding, etc. requires the welders to have a high level of skills, otherwise it is easy to cause damage to the plate, and the use of roll welding process can avoid this problem. However, when welding with existing roll welding machines, since most of the shelf columns are made of angle steel or plates bent into a right angle, it is impossible to place the mesh plate on the side wall of the column after stable placement, which makes welding very inconvenient. Summary of the invention

[0005] The technical solution of the present invention is achieved in this way:

[0010] Transverse translation mechanism: fixed on the two longitudinal translation mechanisms, the transverse translation mechanism is equipped with a roll welding mechanism, and the roll welding mechanism can be driven to move horizontally through the transverse translation mechanism;

[0011] The rolling welding mechanism comprises a fixing frame installed on the lateral translation mechanism, a welding wheel is rotatably installed at one end of the fixing frame, and the distance between the welding wheel and the upper surface of the clamping mechanism is adjustable.

[0012] Furthermore, the two clamping mechanisms are arranged opposite to each other, and there is a distance of at least one centimeter between a side of the clamping mechanism close to the side wall of the frame and the side wall of the frame.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] like Figure 1-Figure 6 As shown, a seam welding machine for welding shelf plates comprises a frame 1, a clamping mechanism 2, a longitudinal translation mechanism 3, a transverse translation mechanism 4, and a seam welding mechanism 5.

[0031] Rack 1: It is a U-shaped structure. A step for installing the clamping mechanism 2 is formed on the inner side of the rack 1. The interior of the rack 1 is a hollow structure for installing electrical appliances and wiring;

[0032] Clamping mechanism 2: There are two in total. The two clamping mechanisms 2 are symmetrically fixed on the frame 1. The clamping mechanism 2 includes a fixed plate 201 and a movable plate 202 plugged together. The fixed plate 201 is fixed to the frame 1 through a support frame 203 fixed thereunder. A plurality of parallel slots 204 are formed on the fixed plate 201. A spline 205 plugged into the slots 204 is formed on the movable plate 202. A transmission shaft 207 is fixed below the fixed plate 201 through a bearing seat 206. A plurality of gears 209 are fixed on the transmission shaft 207. The gears 209 are arranged opposite to the slots 204. A fixed vertical plate 210 is fixed below one end of which the spline 205 corresponding to the gear 209 is inserted into the slot 204 by screws. A horizontally arranged rack 211 is fixed to the lower end of the fixed vertical plate 210. The rack 211 is meshed with the gear 209. The fixed vertical plate 210 is symmetrically fixed on both sides of one end away from the rack 211. A horizontal slider 213, a support rail 212 is fixed on the lower surface of the fixed plate 201 and is installed in cooperation with the horizontal slider 213. A driving motor 208 connected to the transmission shaft 207 is fixed at one end of the fixed plate 201. The driving motor 208 is a servo motor and can rotate forward and reverse. The cooperation between the horizontal slider 2013 and the support rail 212 can ensure that the movable plate 202 is fixed horizontally. The transmission shaft 207 is driven to rotate by the driving motor 208, which can drive the gear 209 to rotate. When the gear 209 rotates, it drives the rack 211 meshing with it to move horizontally to drive the movable plate 202 to move relative to the fixed plate 201. The width of the clamping mechanism 2 can be adjusted to realize the expansion of the articles covered on the clamping mechanism 2, and the two clamping mechanisms 2 can be used to clamp and fix the workpiece. The width and lateral telescopic length of the two clamping mechanisms 2 can be different to increase the processing range of the equipment.

[0033] There are two longitudinal translation mechanisms 3, which are symmetrically fixed on the frame 1. The longitudinal translation mechanisms 3 are arranged along the length direction of the clamping mechanism 2. The transverse translation mechanism 4 is driven by the two longitudinal translation mechanisms 3 to move longitudinally and horizontally above the clamping mechanism 2;

[0034] Transverse translation mechanism 4: fixed on the two longitudinal translation mechanisms 3, a roll welding mechanism 5 is installed on the transverse translation mechanism 4, and the roll welding mechanism 5 can be driven to move horizontally through the transverse translation mechanism 4. The cooperation of the longitudinal translation mechanism 3 and the transverse translation mechanism 4 can drive the roll welding mechanism 5 to adjust the position in the plane to realize welding at different positions;

[0035] The rolling welding mechanism 5 comprises a fixing frame 51 mounted on the lateral translation mechanism 4, a welding wheel 53 is rotatably mounted on one end of the fixing frame 51, and the distance between the welding wheel 53 and the upper surface of the clamping mechanism 2 is adjustable, so as to facilitate the welding of materials with different thicknesses.

[0036] In this embodiment, the two clamping mechanisms 2 are arranged opposite to each other, and there is a distance of at least one centimeter between the side of the clamping mechanism 2 close to the side wall of the frame 1 and the side wall of the frame 1, so that when welding the shelf columns on both sides of the mesh plate, the already welded shelf columns can be placed in the space between the clamping mechanism 2 and the frame 1, so as to ensure that the shelf mesh plate is horizontally laid on the clamping mechanism 2 waiting for welding on the other side.

[0037] In this embodiment, the longitudinal translation mechanism 3 includes a first screw 31 and a longitudinal guide rail 34 installed in parallel on the frame 1. The first screw 31 is rotatably mounted with the frame 1 through a bearing. A longitudinal drive motor 32 connected to the first screw 31 is fixed at one end of the frame 1. The first screw 31 is rotatably engaged with the first ball sleeve 33. A longitudinal slider 46 is slidably mounted on the longitudinal guide rail 34. The longitudinal slider 46 is fixed to the first ball sleeve 33. The first screw 31 is driven to rotate by the longitudinal drive motor 32, and the first ball sleeve 33 and the longitudinal slider 46 can be driven to move along the length direction of the first screw 31.

[0038] In this embodiment, the transverse translation mechanism 4 includes a transverse optical axis 47 whose two ends are fixed on two first ball sleeves 33 and a second screw 41 and a transverse guide rail 44 whose two ends are fixed on two longitudinal sliders 46. A transverse motor 42 that is transmission-connected to the second screw 41 is fixed on one of the longitudinal sliders 46. A second ball sleeve 43 is rotatably mounted on the second screw 41. The second ball sleeve 43 is slidably mounted on the transverse guide rail 44. The second screw 41 is rotated by the transverse motor 42, and the second ball sleeve 43 can be driven to move along the length direction of the second screw 41. A plurality of threading rings 45 are nested on the transverse guide rail 44. The threading rings 45 can be used to hang and fix the wire pipe connected to the rolling welding mechanism 5 to avoid the pipeline being scattered.

[0039] In this embodiment, the fixing frame 51 is slidably installed on the transverse optical axis 47 through the welding wheel 53. A telescopic rod 54 is installed at one end of the fixing frame 51 away from the welding wheel 53. The two ends of the telescopic rod 54 are respectively hinged with the second ball sleeve 43 and the fixing frame 51 through a pin shaft. The power source of the telescopic rod 54 is any one of hydraulic oil, high-pressure gas source, and electricity. The telescopic rod 54 drives the fixing frame 51 to rotate and then drives the welding wheel 53 to approach or move away from the workpiece to be welded.

[0040] In this embodiment, a drag chain 6 with one end installed together with the lateral translation mechanism 4 is fixed on the upper end surface of the frame 1. The drag chain 6 can not only maintain the stability of the movement of the lateral translation mechanism 4, but also the interior of the drag chain 6 is a hollow structure, which can protect the pipeline connected to the rolling welding mechanism 5.

[0041] The working principle of the present invention is:

[0042] When welding, when welding the mesh plate on the first column, the column is placed between the two clamping mechanisms 2, and the two movable plates 202 are driven by the driving motor 208 to move toward each other to clamp the column, and then the mesh plate is laid on the upper surface of the clamping mechanism 2, and the position of the mesh plate is adjusted so that the edge of the mesh plate is placed on the shelf column and parallel to it, and then the position of the rolling welding mechanism 5 is adjusted by the longitudinal translation mechanism 3 and the transverse translation mechanism 4, so that the welding wheel 53 is close to one end of the column, and the fixed frame 51 is driven to rotate by the telescopic rod 54 to drive the welding wheel 53 to move down and contact the mesh plate, and then start rolling welding. As the first screw 31 rotates, the welding wheel 53 is driven to move along the length direction of the shelf column to weld the edge of the mesh plate to the side wall of the shelf column. When the welding of one of the columns is completed, one end of the welded column is placed on the clamping mechanism 2 close to the end of the frame 1, so that the mesh plate can be placed horizontally on the clamping mechanism 2, and at the same time, the other shelf column is clamped between the two clamping mechanisms 2. The position of the shelf column is adjusted and welding can be carried out.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
