Description

Technical Field

[0001] The utility model belongs to the technical field of welding auxiliary devices, and in particular relates to a workpiece welding butt auxiliary frame. Background Art

[0002] Welding, also known as fusion, is a manufacturing process and technology that joins metals or other thermoplastic materials such as plastics by heating, high temperature or high pressure. Welding has a wide range of applications and can be used for both metals and non-metals.

[0003] The related technology (publication number CN221134629U) discloses a docking device for workpiece welding. When fixing the round tube, first lift the guide block with one hand, and put the round tube into the semicircular clamp with the other hand. After adjusting the position, let go, the compression spring automatically presses the round tube, loosen the bolt, rotate the base with the support cylinder, and the arc-shaped slider slides on the workbench surface. After adjusting the required angle, rotate the screw until the two round tubes contact, and finally tighten the bolts. The base is fixed and cannot rotate, and welding can be carried out at this time. In summary, this device not only fixes the round tube conveniently but also can be fixed at multiple angles.

[0004] Before welding plate-shaped workpieces, existing devices usually move the two workpieces toward the center for docking. During this process, it is difficult to ensure that the two workpieces move synchronously and parallel to the center. The individual workpieces are easily skewed when they are moved horizontally, which leads to the deflection of the docking point of the two workpieces, affecting the straightness of the docking welds of the two workpieces. Utility Model Content

[0005] In response to the existing problems of the single workpiece being easily skewed when it is translated separately, which in turn leads to the deflection of the joint between the two workpieces and affects the straightness of the butt welds between the two workpieces, the utility model provides a workpiece welding butt joint auxiliary frame. By setting up four sets of positioning jaws that move synchronously toward the center, the two workpieces are pushed toward the center synchronously. Compared with the method of butt jointing by moving the single workpieces separately, it can better ensure the straight connection of the joint, thereby ensuring the straightness of the butt welds between the two workpieces. The specific technical solution is as follows:

[0006] The first gear and the second gear are connected with each other via a toothed connection, and the toothed connection is connected with the toothed connection of the gear train, and the toothed connection is connected with the toothed connection of the gear train.

[0007] In the above technical solution, the rear end of the first connecting rod and the rear end of the second connecting rod are located on the same horizontal line, and the front end of the third connecting rod and the front end of the fourth connecting rod are located on the same horizontal line.

[0008] In the above technical solution, the first connecting rod is slidably embedded in the second sliding groove, the second connecting rod is slidably embedded in the first sliding groove, and the third connecting rod and the fourth connecting rod are slidably embedded in the third sliding groove.

[0009] In the above technical solution, support assemblies are respectively provided on the front and rear sides of the first gear;

[0010] Each group of the support components includes a mounting bracket installed in the inner cavity of the shell, a fixing rod is fixedly installed on the mounting bracket, and support plates are fixedly installed on the left and right ends of the fixing rod, a first limit bar and a second limit bar are vertically installed between the two support plates, and the first limit bar is arranged parallel to the second limit bar, a first slider is provided on the sliding sleeve of the first limit bar, and a second slider is provided on the sliding sleeve of the second limit bar.

[0011] In the above technical solution, there are two first sliders, and the two first sliders are connected to the second rack and the first rack respectively; there are two second sliders, and the two second sliders are connected to the third rack and the fourth rack respectively.

[0012] In the above technical solution, the docking assembly includes a bracket and a positioning clamp, the positioning clamp is fixedly mounted on the bracket, and the positioning clamps on the left and right sides are arranged opposite to each other.

[0013] In the above technical solution, the side wall of the housing is provided with a driving assembly;

[0014] The driving assembly includes a supporting seat installed on the side wall of the shell, and a cylinder is installed on the top of the supporting seat.

[0015] In the above technical solution, the cylinder output end is connected to one set of the docking components.

[0016] Compared with the prior art, the workpiece welding butt auxiliary frame of the utility model has the following beneficial effects:

[0017] First, in order to solve the problem that the existing device easily causes skewness in the method of parallel movement of individual workpieces before welding plate-shaped workpieces, which leads to the deflection of the joint between the two workpieces and affects the straightness of the welds between the two workpieces, the utility model provides four sets of positioning jaws, which can move synchronously toward the middle and push the two workpieces toward the middle synchronously. The left and right sets of positioning jaws move synchronously toward the middle, which can better ensure the straight connection of the joint and thus ensure the straightness of the welds between the two workpieces compared to the method of parallel movement of individual workpieces.

[0018] Second, the present invention provides a rotating shaft, a first gear, and a second gear, and can realize the synchronous movement of the above four by moving one of the first rack, the second rack, the third rack, or the fourth rack, thereby realizing the synchronous movement of the above four groups of positioning jaws toward the middle, realizing the linkage of the four groups of positioning jaws. Compared with the method of adjusting the position of the positioning jaws one by one, the synchronization is higher, and the synchronization of the docking movement of the left and right groups of positioning jaws can be better ensured;

[0019] 3. The utility model can drive the first rack and the second rack to move synchronously toward the middle by rotating the first gear, so as to realize the synchronous relative movement of the positioning claws on the first connecting rod and the second connecting rod. The second gear can drive the positioning claws on the third rack and the fourth rack to move synchronously relative to each other, thereby realizing the synchronous movement of the left and right positioning claws toward the middle and realizing the docking of the two workpieces.

[0020] Fourth, the utility model can limit the movement direction of the first and second limiting bars through the mounting frame, the fixing rod, the support plate, the first limiting bar and the second limiting bar, ensuring that the first and second limiting bars move straight and will not tip over;

[0021] 5. The utility model drives the movement of one of the first rack, the second rack, the third rack or the fourth rack through the cylinder, thereby driving the synchronous linkage of all the positioning jaws;

[0022] In summary, the utility model realizes the synchronous pushing of two workpieces toward the middle by setting four groups of positioning clamps to move toward the middle synchronously. Compared with the method of separately moving and docking a single workpiece, it can better ensure the straight connection of the docking joint, and thus ensure the straightness of the docking welds of the two workpieces.

The cam 5 is provided with a second gear 6 and a second gear 7. The cam 5 is provided with a second gear 6 and a second gear 7. They are arranged in parallel, and a second connecting rod 10 is installed at the right end of the first rack 7, and a first connecting rod 9 is installed at the left end of the second rack 8. The second connecting rod 10 is driven to move synchronously by the moving block of the first rack 7, and the first connecting rod 9 is driven to move synchronously by the movement of the second rack 8. A third connecting rod 14 is installed at the left end of the third rack 12, and a fourth connecting rod 15 is installed at the right end of the fourth rack 13. The third connecting rod 14 is driven to move synchronously by the movement of the third rack 12, and the fourth connecting rod 15 is driven to move synchronously by the movement of the fourth rack 13. Docking assemblies are respectively installed on the top ends of the first connecting rod 9, the second connecting rod 10, the third connecting rod 14 and the fourth connecting rod 15. Through the movement of the first connecting rod 9, the second connecting rod 10, the third connecting rod 14 and the fourth connecting rod 15, the four groups of docking assemblies are moved synchronously. The four groups of docking assemblies moving toward the middle can realize the synchronous movement and docking of the workpieces from both sides to the middle, so as to assist the subsequent welding device in the welding processing of the welds of the two workpieces.

[0031] Specific reference Figure 2 and Figure 3As shown, the rear end of the first connecting rod 9 is located on the same horizontal line as the rear end of the second connecting rod 10, thereby ensuring that the docking assemblies respectively arranged at the top ends of the first connecting rod 9 and the second connecting rod 10 can be located on the same horizontal line, and the front end of the third connecting rod 14 is located on the same horizontal line as the front end of the fourth connecting rod 15, thereby ensuring that the docking assemblies respectively arranged at the top ends of the third connecting rod 14 and the fourth connecting rod 15 can be located on the same horizontal line, thereby ensuring that the docking assemblies can be arranged symmetrically in pairs, ensuring that the two subsequent corresponding left and right groups of docking assemblies can synchronously push the two workpieces to the middle to achieve stable docking of the two workpieces; the first connecting rod 9 is slidably embedded in the second slide groove 3, the second connecting rod 10 is slidably embedded in the first slide groove 2, and the third connecting rod 14 and the fourth connecting rod 15 are slidably embedded in the third slide groove 4, and the moving direction of the first connecting rod 9 is limited by the second slide groove 3, the moving direction of the second connecting rod 10 is limited by the first slide groove 2, and the moving direction of the third connecting rod 14 and the fourth connecting rod 15 can be limited by the third slide groove 4.

[0032] Main references Figures 3 to 5 As shown, support assemblies are respectively provided on the front and rear sides of the first gear 6; each group of support assemblies includes a mounting frame 16 installed in the inner cavity of the shell 1, and a fixing rod 17 is fixedly installed on the mounting frame 16, and support plates 18 are respectively fixedly installed on the left and right ends of the fixing rod 17, and a first limit bar 19 and a second limit bar 20 are vertically installed between the two support plates 18, and the first limit bar 19 is arranged parallel to the second limit bar 20, and a first slider 21 is provided on the sliding sleeve of the first limit bar 19, and a second slider 22 is provided on the sliding sleeve of the second limit bar 20. Under the action of external force, the first slider 21 can move along the first limit bar 19, and the second slider 22 can move along the second limit bar 20.

[0033] Main references Figure 3 As shown, two first sliders 21 are provided, and the two first sliders 21 are connected to the second rack 8 and the first rack 7 respectively. When the first rack 7 or the second rack 8 moves, it can drive the first slider 21 installed on the corresponding outer wall to move along the first limit bar 19 at the corresponding position, and the moving direction of the first slider 21 is limited by the first limit bar 19, thereby realizing the limitation in the moving direction of the first rack 7 and the second rack 8. Two second sliders 22 are provided, and the two second sliders 22 are connected to the third rack 12 and the fourth rack 13 respectively. When the first third rack 12 or the fourth rack 13 moves, it can drive the second slider 22 installed on the corresponding outer wall to move along the second limit bar 20 at the corresponding position. The moving direction of the second slider 22 is limited by the second limit bar 20, thereby realizing the limitation in the moving direction of the first third rack 12 and the fourth rack 13.

[0034] Specific reference Figure 3 and Figure 4 As shown, the docking assembly includes a bracket 23 and a positioning clamp 24. The positioning clamp 24 is fixedly mounted on the bracket 23, and the positioning clamps 24 on the left and right sides are arranged opposite to each other. The positioning clamps 24 respectively arranged on the first connecting rod 9, the second connecting rod 10, the third connecting rod 14, and the fourth connecting rod 15 move synchronously toward the middle to drive the two workpieces respectively arranged in the inner cavities of the positioning clamps 24 on the left and right sides to the middle to achieve docking at the weld.

[0035] In addition, the main reference Figure 2 and Figure 3 As shown, a driving assembly is provided on the side wall of the shell 1; the driving assembly includes a supporting seat 25 installed on the side wall of the shell 1, and a cylinder 26 is installed on the top of the supporting seat 25. The opened cylinder 26 drives the bracket 23 connected to the output end of the cylinder 26 to move to the left, so as to prompt the second connecting rod 10, the first rack 7 and the positioning claw 24 provided on the second connecting rod 10 to move to the left, so as to realize the subsequent synchronous movement of all positioning claws 24 to the middle.

[0036] The output end of the cylinder 26 is connected to one of the docking assemblies. In the present embodiment, the cylinder 26 is connected to the docking assembly on the second connecting rod 10. Of course, the cylinder 26 can be selectively connected to any one of the docking assemblies provided on the first connecting rod 9, the second connecting rod 10, the third connecting rod 14, and the fourth connecting rod 15. Thus, the cylinder 26 can drive one of the first rack 7, the second rack 8, the third rack 12 or the fourth rack 13 to move, thereby driving the synchronous linkage of all the positioning jaws 24.

[0037] It is worth noting that the cylinder 26 used in this application is a self-locking cylinder commonly used on the market, and its output end can stay at any position and be locked; the above-mentioned existing components will not be described in detail here.

[0038] The working principle of the workpiece welding butt auxiliary frame in this embodiment is as follows:

[0039] The opened cylinder 26 drives the bracket 23 connected to the output end of the cylinder 26 to move to the left, so as to prompt the second connecting rod 10, the first rack 7 and the positioning claw 24 provided on the second connecting rod 10 to move to the left. The first rack 7 moving to the left drives the first gear 6 to rotate counterclockwise. At this time, the first gear 6 drives the rotating shaft 5 and the second gear 11 to rotate counterclockwise synchronously. At the same time, the counterclockwise rotating first gear 6 drives the second rack 8 to move to the right, prompting the first connecting rod 9 and the positioning claw 24 provided on the first connecting rod 9 to move to the right, thereby realizing that the positioning claw 24 on the first connecting rod 9 and the positioning claw 24 on the second connecting rod 10 move synchronously toward the middle; at the same time, the counterclockwise rotating second gear 11 prompts the third rack 12 to move to the right. To promote the third rack 12, the third connecting rod 14 and the positioning claw 24 on the third connecting rod 14 to move synchronously to the right, the counterclockwise rotation of the second gear 11 promotes the fourth rack 13 to move left, so as to promote the fourth rack 13, the fourth connecting rod 15 and the positioning claw 24 on the fourth connecting rod 15 to move synchronously to the left, thereby achieving the positioning claw 24 on the third connecting rod 14 and the positioning claw 24 on the fourth connecting rod 15 to move synchronously toward the middle; that is, through the drive of the cylinder 26, the positioning claws 24 respectively provided on the first connecting rod 9, the second connecting rod 10, the third connecting rod 14 and the fourth connecting rod 15 are moved synchronously toward the middle, so as to drive the two workpieces respectively provided in the inner cavities of the positioning claws 24 on the left and right sides to the middle to achieve docking at the weld;

[0040] The utility model realizes synchronous pushing of two workpieces toward the middle by arranging four groups of positioning jaws 24 to move toward the middle synchronously. Compared with the method of separately moving and docking a single workpiece, it can better ensure the straight connection of the docking joint, thereby ensuring the straightness of the docking welds of the two workpieces.
