Description

Technical Field

[0001] The utility model relates to the technical field of automatic welding production lines, and more particularly, to an automatic pushing and welding tooling and an automatic welding production line equipment. Background Art

[0002] In an automatic welding production line, in order to improve the welding efficiency, an automatic welding tooling is used to position and fix welding workpieces, so as to greatly improve the positioning and clamping efficiency.

[0003] In addition, for the positioning and clamping of plate workpieces, especially for plate workpieces before rough machining, it is often necessary to keep pushing from multiple different directions to always keep two plate workpieces in a pushed state, so as to prevent the thermal deformation during welding from affecting the welding quality at the butt joint of the two plate workpieces.

[0004] However, even so, the welding quality at the butt joint of the two plate workpieces is still unstable, sometimes good and sometimes bad. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is how to improve the stability of the welding quality at the butt joint of two plate workpieces in an automatic welding production line of plate workpieces.

[0006] To solve the above problems, the utility model provides an automatic pushing and welding tooling for an automatic welding production line equipment. The automatic pushing and welding tooling includes:

[0007] A welding platform for placing a first plate workpiece and a second plate workpiece;

[0008] A lateral pusher, including a lateral telescopic mechanism, a lateral push arm and a plurality of drag reduction components. The lateral push arm is connected to the telescopic member of the lateral telescopic mechanism. The lateral push arm is placed on the same side of the first plate workpiece and the second plate workpiece. A push protrusion for pushing the second plate workpiece is provided on the surface of the lateral push arm facing the second plate workpiece. The plurality of drag reduction components are sequentially arranged along the edge of the lateral push arm facing the first plate workpiece. The surface of each drag reduction component facing the first plate workpiece is a first arc surface, and the axis of the first arc surface is vertically arranged;

[0009] A stop arm connected to the welding platform, and the first plate workpiece is arranged between the stop arm and the lateral push arm; and

[0010] A longitudinal pusher for pushing the first plate workpiece backward;

[0011] Wherein, the conveying device of the automatic welding production line equipment is used to push the second plate workpiece forward.

[0012] Optionally, the resistance reducing component is a cylinder. The transverse pushing arm is provided with a plurality of limiting grooves, and each resistance reducing component is arranged in one of the limiting grooves. The side surface of the resistance reducing component protruding from the opening of the limiting groove is a first arc surface, and the limiting groove is used to prevent the resistance reducing component from separating from the transverse pushing arm.

[0013] Optionally, the limiting groove penetrates the transverse pushing arm from top to bottom. The side wall surface of the limiting groove is a second arc surface, the axis of the second arc surface is vertically arranged, and the width of the opening of the limiting groove is smaller than the diameter of the resistance reducing component.

[0014] Optionally, a cover plate is arranged on the top surface of the transverse pushing arm. The cover plate is arranged above the resistance reducing component, and the cover plate is detachably connected to the transverse pushing arm. The cover plate is used to prevent the resistance reducing component from moving up and down along the limiting groove.

[0015] Optionally, the automatic pushing and welding tooling further includes a base, and the welding platform, the transverse telescopic mechanism and the longitudinal pusher are all arranged on the base.

[0016] Optionally, the transverse pushing arm is L-shaped, the pushing protrusion is the short arm of the transverse pushing arm, and the long arm of the transverse pushing arm extends along the front-rear direction.

[0017] Optionally, the transverse telescopic mechanism includes a cylinder and a piston rod. The piston rod is placed in the cylinder, and the piston rod is the telescopic member of the transverse telescopic mechanism.

[0018] Optionally, the blocking arm is a plate-like structure arranged vertically, and the blocking arm is detachably connected to one side edge of the welding platform.

[0019] Optionally, one side surface of the pushing protrusion is a plane, and one side surface of the pushing protrusion is used to push the second plate-like workpiece. One side surface of the pushing protrusion and the outermost generatrix of the plurality of first arc surfaces are in the same vertical plane.

[0020] In addition, the present invention also provides an automatic welding production line equipment, and the automatic welding production line equipment includes the automatic pushing and welding tooling described above.

[0021] The technical effects of the present invention at least include:

[0022] Only the first plate-like workpiece is laterally clamped by using the retaining arm and the lateral pushing arm, instead of clamping the first plate-like workpiece and the second plate-like workpiece simultaneously, so as to avoid the first plate-like workpiece being unable to move back and forth relative to the second plate-like workpiece. Then, since the surface of each of the resistance-reducing components facing the first plate-like workpiece is a first arc surface, the clamping force of the lateral pushing arm on the first plate-like workpiece is reduced. More precisely, the first arc surface is used to reduce the contact friction force between the first plate-like workpiece and the resistance-reducing component. Moreover, the second plate-like workpiece is pushed by the pushing protrusion, thus playing a guiding role to ensure accurate positioning of the first plate-like workpiece and the second plate-like workpiece in the front-back direction. In addition, the conveying device of the automatic welding production line equipment pushes the second plate-like workpiece forward, while the longitudinal pusher pushes the first plate-like workpiece backward, so that the first plate-like workpiece and the second plate-like workpiece are more likely to be closely attached together, effectively eliminating the gap between the first plate-like workpiece and the second plate-like workpiece. Thus, the gap between the two plate-like workpieces is effectively pushed and eliminated from the front end or the rear end, improving the stability of the welding quality at the butt joint of the two plate-like workpieces.

[0033] See Figures 1 to 3 , this embodiment provides an automatic pushing and welding tooling for an automatic welding production line equipment, including:

[0034] A welding platform 1 for placing a first plate-like workpiece 2 and a second plate-like workpiece 3;

[0035] A transverse pusher 4, including a transverse telescopic mechanism 41, a transverse push arm 42 and a plurality of drag reduction components 43. The transverse push arm 42 is connected to the telescopic member of the transverse telescopic mechanism 41. The transverse push arm 42 is placed on the same side of the first plate-like workpiece 2 and the second plate-like workpiece 3. A pushing protrusion 423 for pushing the second plate-like workpiece 3 is provided on the side surface of the transverse push arm 42 facing the second plate-like workpiece 3. The plurality of drag reduction components 43 are sequentially arranged along the side edge of the transverse push arm 42 facing the first plate-like workpiece 2. The surface of each drag reduction component 43 facing the first plate-like workpiece 2 is a first arc surface, and the axis of the first arc surface is vertically arranged;

[0036] A stop arm 6, connected to the welding platform 1, and the first plate-like workpiece 2 is arranged between the stop arm 6 and the transverse push arm 42; and

[0037] A longitudinal pusher 5 for pushing the first plate-like workpiece 2 backward;

[0038] Wherein, the conveying device of the automatic welding production line equipment is used to push the second plate-like workpiece 3 forward.

[0039] In the process of analyzing the above problems, the inventor of the present utility model found that the main reason for the still unstable welding quality at the butt joint of two plate-like workpieces is that the existing clamping device clamps the left and right sides of the two plate-like workpieces simultaneously, causing the two plate-like workpieces to be clamped simultaneously and unable to move forward and backward. When subsequently pushing the plate-like workpieces from the front or the rear, since the above-mentioned clamping device has made the two plate-like workpieces unable to move forward and backward, it is impossible to effectively push and eliminate the gap between the two plate-like workpieces from the front or the rear, resulting in unstable welding quality at the butt joint of the two plate-like workpieces.

[0040] Therefore, in the present utility model, the first plate-like workpiece 2 is only laterally clamped by the retaining arm 6 and the transverse pushing arm 42, instead of clamping the first plate-like workpiece 2 and the second plate-like workpiece 3 simultaneously, so as to avoid the first plate-like workpiece 2 being unable to move forward and backward relative to the second plate-like workpiece 3. Then, by using the surface of each of the resistance-reducing components 43 facing the first plate-like workpiece 2 as a first arc surface, the clamping force of the transverse pushing arm 42 on the first plate-like workpiece 2 is reduced. More precisely, the first arc surface is used to reduce the contact friction force between the first plate-like workpiece 2 and the resistance-reducing component 43. And, the second plate-like workpiece 3 is pushed by the pushing protrusion 423, so as to play a guiding role and ensure the accurate positioning of the first plate-like workpiece 2 and the second plate-like workpiece 3 in the front-back direction. In addition, the conveying device of the automatic welding production line equipment pushes the second plate-like workpiece 3 forward, and the longitudinal pusher 5 pushes the first plate-like workpiece 2 backward, so that the first plate-like workpiece 2 and the second plate-like workpiece are more easily pressed against each other, effectively eliminating the gap between the first plate-like workpiece 2 and the second plate-like workpiece. Thus, the gap between the two plate-like workpieces can be effectively pushed and eliminated from the front or the rear, improving the stability of the welding quality at the butt joint of the two plate-like workpieces.

[0041] See Figures 1 to 3 Furthermore, the resistance-reducing component 43 is a cylinder, the transverse pushing arm 42 is provided with a plurality of limiting grooves 421, each resistance-reducing component 43 is arranged in one of the limiting grooves 421, and the side surface of the resistance-reducing component 43 protruding from the opening of the limiting groove 421 is a first arc surface. The limiting groove 421 is used to prevent the resistance-reducing component 43 from separating from the transverse pushing arm 42.

[0042] The limiting groove 421 can not only prevent the resistance-reducing component 43 from separating from the transverse pushing arm 42, but also enable the cylinder to roll inside it, thus changing the sliding friction between the resistance-reducing component 43 and the first plate-like workpiece 2 into rolling friction, further reducing the resistance when the longitudinal pusher 5 pushes the first plate-like workpiece 2.

[0043] See Figures 1 to 3, Further, the limiting groove 421 penetrates the transverse pushing arm 42 from top to bottom. The side wall surface of the limiting groove 421 is a second arc surface, the axis of the second arc surface is vertically arranged, and the width of the opening of the limiting groove 421 is smaller than the diameter of the resistance reducing component 43. Thus, the resistance reducing component 43 is prevented from separating from the transverse pushing arm 42.

[0044] Preferably, the diameter of the corresponding arc of the second arc surface of the limiting groove 421 is equivalent to the diameter of the corresponding arc of the first arc surface of the resistance reducing component 43, so that the two are in clearance fit. The resistance reducing component 43 is prevented from shaking in the limiting groove 421.

[0045] Preferably, the automatic push-top welding tooling further includes a base, and the welding platform 1, the transverse telescopic mechanism 41, and the longitudinal push-top device 5 are all arranged on the base.

[0046] Preferably, the longitudinal push-top device 5 is a cylinder piston device or an electric push rod device.

[0047] See Figures 1 to 3 , Further, a cover plate 422 is arranged on the top surface of the transverse pushing arm 42. The cover plate 422 is arranged above the resistance reducing component 43. The cover plate 422 is detachably connected to the transverse pushing arm 42, and the cover plate 422 is used to prevent the resistance reducing component 43 from moving up and down along the limiting groove 421.

[0048] See Figures 1 to 3 , Further, the cover plate 422 is detachably connected to the transverse pushing arm 42 through a threaded connector.

[0049] See Figures 1 to 3 , Further, the transverse pushing arm 42 is L-shaped, the pushing protrusion 423 is the short arm of the transverse pushing arm 42, and the long arm of the transverse pushing arm 42 extends along the front-rear direction. The transverse pushing arm 42 is integrally formed.

[0050] See Figures 1 to 3 , Further, the transverse telescopic mechanism 41 includes a cylinder and a piston rod. The piston rod is placed in the cylinder, and the piston rod is the telescopic member of the transverse telescopic mechanism 41.

[0051] See Figures 1 to 3 , Further, the blocking arm 6 is a plate-like structure arranged vertically, and the blocking arm 6 is detachably connected to one side edge of the welding platform 1.

[0052] The blocking arm 6 is prone to being squeezed and deformed by the first plate-like workpiece 2 after being used for a period of time. Therefore, it needs to be replaced regularly. By detachably connecting the blocking arm 6 to one side edge of the welding platform 1, the replacement is convenient. Preferably, the detachable connection is realized through a threaded connector.

[0053] See Figures 1 to 3 , further, one surface of the pushing protrusion 423 is a flat surface, and the one surface of the pushing protrusion 423 is used to push the second plate-like workpiece 3, and the one surface of the pushing protrusion 423 and the outermost generatrix of the plurality of first arc surfaces are in the same vertical plane.

[0054] That is to say, the protruding surface of the pushing protrusion 423 is flush with the outermost vertical edge of the first arc surface, so as to ensure that one side edge of the first plate-like workpiece 2 and the second plate-like workpiece 3 are aligned on the same straight line.

[0055] In addition, this embodiment also provides an automatic welding production line device, and the automatic welding production line device includes the automatic pushing and welding tooling described above.

[0056] Since the technical effects obtained by the automatic welding production line device are the same as those of the automatic pushing and welding tooling, the automatic welding production line device will not be explained anymore.

[0057] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present disclosure, and these changes and modifications will all fall within the protection scope of the present invention.
