Description

Technical Field

[0001] The utility model relates to the technical field of welding processing, in particular to a welding tool for a barrel segment product. Background Art

[0002] The half-cylinder products in the prior art are generally formed by bending sheet metal. When two sets of half-cylinder products are welded, the weld trajectory is a straight weld, and the weld is a butt weld. Figure 1 The figure shows the overall structure of a single group of half-cylinder segment products in the prior art and the state of two groups of half-cylinder segment products arranged relative to each other and waiting to be welded, wherein 101 represents a half-cylinder segment product, 102 represents a convex portion at the end of the half-cylinder segment product, and the two groups of half-cylinder segment products constitute a complete cylinder segment product, 103 represents one end portion of the cylinder segment product, 104 represents one side portion of the cylinder segment product, and 105 represents the top portion of the cylinder segment product.

[0003] After searching, the patent document with authorization announcement number CN218906355U discloses a radial laser welding device for cylindrical products. The welding device includes a chassis, an XY-axis moving mechanism, a laser welding head, a clamping and rotating device, and an extrusion device. The XY-axis moving mechanism is installed inside the chassis. The XY-axis moving mechanism includes a first moving component and a second moving component. The first moving component is horizontally placed inside the chassis, and the second moving component is longitudinally installed on the first moving component. The second moving component is perpendicular to the first moving component. The laser welding head is installed on the second moving component. The clamping and rotating device is installed inside the chassis and is located below the laser welding head. The extrusion device is arranged inside the chassis facing the clamping and rotating device.

[0004] When the aforementioned welding equipment is in use, the clamping and rotating device and the extrusion device cooperate to ensure that the upper and lower parts of the cylindrical product are always compressed, while rotating the cylindrical product. However, this clamping method does not effectively clamp the entire cylindrical product. For example, the ends of the cylindrical product are not clamped and fixed. During the subsequent welding process, the lack of clamping and fixing of the ends of the cylindrical product can cause problems such as excessive weld gaps or weld position deviations, affecting the welding effect and even causing the product to be scrapped.

[0005] If, in order to solve the above problem, a clamping component for clamping the end of the barrel product is simply added to the working cabinet, and the horizontal movement of the clamping component is subsequently used to achieve the clamping limit of the end of the barrel product, since the top of the execution end of the clamping assembly is higher than the end of the barrel product, the presence of the clamping component will interfere with the loading and unloading movement of the barrel product during the horizontal movement of the barrel product. Therefore, the clamping component needs to be disassembled and assembled before and after each welding to ensure the normal loading and unloading movement of the barrel product. Based on this improved clamping method, each welding requires a lot of preliminary preparation work, which greatly reduces the welding process efficiency. In addition, the repeated disassembly and assembly of the clamping component will not only cause the clamping component to be worn faster and affect its service life, but also easily cause failures and cause inconvenience in use.

[0006] To this end, we propose a welding tool for barrel section products to solve the above problems. Utility Model Content

[0007] The purpose of the utility model is to solve the problems in the prior art and to propose a welding jig for barrel segment products. The welding jig adjusts the position of the clamping block used to form the clamping area so that the clamping block has a state in which the barrel segment product can be clamped and limited, and a state in which the barrel segment product cannot be interfered with in loading and unloading. The staff only needs to change the position of the clamping block to make it in the corresponding state. The state switching is convenient and easy to use.

[0008] In order to solve the above problems, the present invention provides the following technical solutions:

[0009] A welding tool for a barrel section product comprises a base and a storage platform located above the base, the top of the storage platform constituting a receiving surface for supporting the barrel section product, and a positioning block is provided on the receiving surface, one end of the storage platform is arranged on the base so that the storage platform as a whole constitutes a cantilever structure, and the other end of the storage platform constitutes a cantilever end for loading and unloading the barrel section product, and a clamping block that can move toward or away from the positioning block is movably provided at the cantilever end, so that the clamping block has a high-position clamping state on the cantilever structure in which it moves toward the positioning block, and a low-position free state in which it moves away from the positioning block, and when the clamping block is in the low-position free state, the clamping block and the loading and unloading path of the barrel section product avoid each other.

[0010] As a further solution of the present invention: when the clamping block moves toward the positioning block, the movement direction of the clamping block can be decomposed into the horizontal feeding direction along the barrel section product and the vertical upward direction; when the clamping block moves away from the positioning block, the movement direction of the clamping block can be decomposed into the horizontal unloading direction along the barrel section product and the vertical downward direction.

[0011] As a further solution of the present invention: a quick-clamp side-push clamping piece for installing the clamping block is provided at the cantilever end, the quick-clamp side-push clamping piece and the clamping block are integrally arranged in an inclined manner, and the quick-clamp side-push clamping piece is used to drive the clamping block to move.

[0012] As a further solution of the present invention: the quick-clamp side-push clamping member includes a quick-clamp mounting block fixedly arranged on the cantilever end, and the quick-clamp mounting block is lower than the supporting surface, a quick-clamp mounting tube is fixedly arranged on the quick-clamp mounting block, a pin is slidably installed on the quick-clamp mounting tube along its length direction, and a notch is provided on the side of the quick-clamp mounting tube along its length direction, a quick-clamp handle passing through the notch is provided on one end of the pin located in the quick-clamp mounting tube, and the quick-clamp handle is hinged to the quick-clamp mounting tube, and the clamping block is fixedly mounted on one end of the pin located outside the quick-clamp mounting tube.

[0013] As a further solution of the present invention: limit blocks are provided on both sides of the clamping block, and the two limit blocks are arranged opposite to each other, so that the clamping block and the two limit blocks form a U-shaped layout.

[0014] As a further solution of the present invention, the distance between the two limiting blocks is adjustable, so that the whole composed of the clamping block and the two limiting blocks has an opening area with adjustable size.

[0015] As a further solution of the present invention: the welding tool also includes a rotating support mechanism arranged at the cantilever end, and the rotating support mechanism includes a rotating support rotatably arranged on the side of the cantilever end, and the rotating support has a first working state that can conflict with the base and a second working state away from the base. When the rotating support is in the first working state, the rotating support conflicts with the base, and the supporting surface on the storage table is arranged horizontally; when the rotating support is in the second working state, the rotating support is away from the base, so that the position of the rotating support does not interfere with the loading and unloading path of the barrel product.

[0016] As a further solution of the present invention: the rotating support mechanism also includes a first locking component, which includes a pliers arranged at the cantilever end and a lock buckle arranged on the base for cooperating with the pliers.

[0018] As a further solution of the utility model: it also includes a side pressing fixture for side pressing the barrel section product and a top pressing fixture for top pressing the barrel section product.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. Through the arrangement of the cantilever structure and the clamping block, on the basis of the existence of the cantilever structure, the tilting movement of the clamping block is used to realize the relative change of the position with the positioning block, so that the clamping block and the positioning block can perform normal clamping and fixing work. At the same time, after switching the state, it will not interfere with the loading and unloading movement of the barrel product. Compared with the disassembly and assembly of the clamping parts in the prior art, the clamping block in the utility model only needs to adjust its position according to the work content, so as to achieve the function of fast clamping and non-interference in the loading and unloading of the barrel product, which is convenient to use.

[0021] 2. The movement direction of the clamping block is decomposed into horizontal and vertical directions to obtain the optimal movement direction of the clamping block, ensuring that the clamping or releasing function can be achieved with the minimum displacement of the clamping block;

[0022] 3. Through the setting of the quick-clamp side push clamping piece, the quick-clamp side push clamping piece is used to drive the clamping block to move accordingly. By driving the quick-clamp handle to rotate 90 degrees, the clamping block can move towards or away from the positioning block, which is convenient to use;

[0023] 4. Through the setting of two limit blocks, the clamping block and the two limit blocks form a U-shaped layout. The U-shaped layout can adapt to the shape of the convex part on the barrel product. The size of the opening area of ​​the U-shaped layout is the length of the convex part. The convex part is clamped and limited, which facilitates the stable positioning of the weld on the barrel product and facilitates the accurate performance of subsequent welding work.

[0024] 5. By setting the distance between the two limit blocks to be adjustable, the whole formed by the clamping block and the two limit blocks can have an adjustable opening area. The size of the opening area can be adjusted according to the length of the convex part, so that the tooling can be used with products of different sizes and has a wide range of uses;

[0025] 6. Through the setting of the rotating support mechanism, the rotating support in the rotating support mechanism has two working states. When the rotating support is in the first working state, the rotating support conflicts with the base, and the supporting surface on the storage platform is arranged horizontally, which makes the barrel product in a horizontal and stable state, facilitating subsequent welding. When the rotating support is in the second working state, the rotating support is away from the base, and the loading and unloading gap between the storage platform and the base is opened, so that the position of the rotating support does not interfere with the loading and unloading path of the barrel product.

[0026] 7. Through the setting of the first lock and the second lock, the first lock can lock the first working state of the rotating support, so that the horizontal state of the cantilever structure can be maintained; the second lock can lock the second working state of the rotating support, so that the loading and unloading gap between the cantilever structure and the base is opened, which facilitates the loading and unloading of the barrel products.

[0036] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0037] like Figure 2-Figure 7 As shown, a welding tool for a cylindrical product includes a base 1, a connecting seat is fixedly provided on the base 1, and a storage table 2 is fixedly provided on the left side of the connecting seat; at this time, for the storage table 2: the storage table 2 is located above the base 1, there is a gap between the storage table 2 and the base 1, and its right end is installed on the base 1 through the connecting seat. The storage table 2 in this state constitutes a cantilever structure. On the basis of this cantilever structure, the gap between the storage table 2 and the base 1 is the loading and unloading gap, and the left end of the storage table 2 constitutes the cantilever end.

[0038] like Figure 2-Figure 5 As shown, specifically, the shape of the storage platform 2 is a rectangular strip, and its top constitutes a receiving surface 201 for carrying two groups of half-cylinder products 101. When in use, the two groups of half-cylinder products 101 are slid to the right from the cantilever end to achieve the placement of the products to be welded. Figure 5 It can be represented by the positions of two groups of half-cylinder products 101 on the storage table 2, and the gap between the two groups of half-cylinder products 101 is the welding seam.

[0039] In order to be able to Figure 5 The two groups of half-barrel products 101 in the state shown are clamped and fixed in all directions, which is convenient for the subsequent welding work. The utility model is provided with an end pressure clamp for clamping and limiting the two ends of the barrel product, a side pressure clamp 8 for clamping and limiting the two sides of the barrel product, and a top pressure clamp 9 for clamping and limiting the top of the barrel product. Since the positions of the side pressure clamp 8 and the top pressure clamp 9 on the cantilever structure will not interfere with the loading and unloading of the barrel product, the side pressure clamp 8 and the top pressure clamp 9 can be set as conventional technical means in the prior art. In order to avoid cumbersome writing, they will not be described here. However, since the end pressure clamp needs to be set at the cantilever end of the cantilever structure to achieve clamping of the end of the barrel product, and the position of the end pressure clamp here will interfere with the loading and unloading path of the barrel product, based on this, the design of the end pressure clamp is explained below to make it meet the use requirements.

[0040] Specifically, such as Figure 2-Figure 4 As shown, the end pressure fixture includes:

[0041] 1) Positioning block 3, which is fixed on the supporting surface 201 of the cantilever structure. Figure 2 the right end of the middle;

[0042] 2) Clamping block 4, which is movably arranged on the cantilever end of the cantilever structure, i.e. Figure 2At the left end of the barrel, the clamping block 4 can move towards or away from the positioning block. In the initial state, the position of the clamping block 4 is lower than the receiving surface 201, and the clamping block 4 is in a low-position free state. After the barrel product is placed on the cantilever structure, the clamping block 4 can be driven to move towards the positioning block 3, and the position of the clamping block 4 will gradually rise until the clamping block 4 presses the end of the barrel product. At this time, the clamping block 4 is in a high-position clamping state, and the side pressed by the clamping block 4 and the barrel product can be set to a vertical plane; when it is necessary to unload or load the material, the clamping block 4 in the high-position clamping state can be driven to reset to the initial state, so that the position of the clamping block 4 will not interfere with the unloading and loading paths of the barrel product.

[0043] 3) A quick-clamping side-push clamping member 5 , which is arranged at the cantilever end of the cantilever structure, serves as a driving member for driving the clamping block 4 to perform corresponding actions.

[0044] There are many situations for the movement direction of the clamping block 4 at the cantilever end, as long as it meets the use requirements of the clamping block 4. The preferred movement direction of the clamping block 4 is described below: the clamping block 4 is arranged as a whole in an inclined manner. Figure 4 As shown in the state, the tilt direction is set to tilt to the upper right. From the decomposition of the movement, it can be seen that the movement direction of the clamping block 4 can be synthesized by the horizontal direction and the vertical direction. When the clamping block 4 moves toward the positioning block 3, the movement direction of the clamping block 4 can be decomposed into the horizontal feeding direction of the barrel product (the horizontal feeding direction can be Figure 5 The vertical upward direction can make the clamping block 4 in the initial state gradually rise to above the receiving surface 201 until it contacts the end of the barrel product; when the clamping block 4 moves away from the positioning block 3, the movement direction of the clamping block 4 can be decomposed into the horizontal feeding direction along the barrel product (the horizontal feeding direction can be represented by Figure 5 The vertical downward direction is indicated by the arrow b in FIG. 4 , and the vertical downward direction can cause the clamping block 4 to gradually descend to the initial state.

[0045] like Figure 4 and Figure 6As shown, for the setting of the above-mentioned quick-clamp side-push clamping member 5, when the clamping block 4 is set to be inclined, the quick-clamp side-push clamping member 5 also needs to be set to a corresponding inclination. Specifically, the quick-clamp side-push clamping member 5 includes a quick-clamp mounting block 501 fixedly set at the cantilever end, and the quick-clamp mounting block 501 is lower than the receiving surface 201, and a quick-clamp mounting tube 502 is fixedly set on the quick-clamp mounting block 501, and a pin shaft 503 is slidably installed on the quick-clamp mounting tube 502 along its length direction, and a notch groove is provided on the side of the quick-clamp mounting tube 502 along its length direction, and a quick-clamp handle 504 passing through the notch groove is provided at one end of the pin shaft 503 located inside the quick-clamp mounting tube 502, and the quick-clamp handle 504 is hinged to the quick-clamp mounting tube 502, and the clamping block 4 is fixedly mounted on one end of the pin shaft 503 located outside the quick-clamp mounting tube 502. Figure 6 In the state shown, when the quick-clamping handle 504 is rotated 90 degrees clockwise, the pin 503 can drive the clamping block 4 to move to the right, and the clamping block 4 moves closer to the positioning block 3 to clamp the barrel product; in this clamping state, if the quick-clamping handle 504 is rotated 90 degrees counterclockwise to Figure 6 The state shown is that the clamping block 4 releases the clamping of the barrel product.

[0046] like Figure 6 As shown, since there is a protrusion 102 on the end of the barrel section product, in order to adaptively clamp and limit the protrusion 102, in some possible embodiments, a limiting block 6 is set on both sides of the clamping block 4, and the two limiting blocks 6 are arranged relative to each other so that the clamping block 4 and the two limiting blocks 6 form a U-shaped layout. The U-shaped layout can adapt to the shape of the protrusion 102, and the size of the opening area of ​​the U-shaped layout is the length of the protrusion 102. In order for the U-shaped layout to adapt to protrusions 102 of different sizes, the distance between the two limiting blocks 6 is adjustable, so that the clamping block 4 and the two limiting blocks 6 form a whole with an adjustable opening area, and the size of the opening area can be adaptively adjusted according to the length of the protrusion 102. Furthermore, for the setting of the adjustable distance between the two limiting blocks 6, a gasket or the like can be added between the limiting block 6 and the clamping block 4. It should be noted that, based on this setting, the overall shape of the positioning block 3 can also be set to the above-mentioned U-shaped layout to effectively clamp and limit the other end of the barrel segment product.

[0047] like Figure 3-Figure 5As shown, since it is necessary to ensure that the cantilever structure and the barrel section product thereon are in a horizontal state during welding, the present invention further includes a rotating support mechanism 7 for keeping the cantilever structure in a horizontal state. Specifically, the rotating support mechanism 7 includes a rotating support 701 rotatably arranged on the side of the cantilever end, and an operating handle 706 is fixedly arranged on the rotating support 701. This article shows a case where two groups of rotating supports 701 are preferably arranged. The rotating support 701 has a first working state in which it can conflict with the base 1 and a second working state away from the base 1. When the rotating support 701 is in the first working state, the rotating support 701 conflicts with the base 1, and the receiving surface 201 on the storage table 2 is arranged horizontally, which means that the barrel section product is in a horizontal state. This state can be controlled by Figure 5 When the rotating support 701 is in the second working state, the rotating support 701 is away from the base 1 so that the position of the rotating support 701 does not interfere with the loading and unloading path of the barrel product. This second working state can be Figure 5 In the first working state shown in , the rotating support 701 is driven to rotate clockwise by a certain angle. After rotating by a certain angle, the loading and unloading gap between the storage table 2 and the base 1 will be opened, and the subsequent barrel products can move through the loading and unloading gap.

[0048] like Figure 4 and Figure 7 As shown, in order to stably open the above-mentioned loading and unloading gap, the rotating support mechanism 7 further includes a second locking member, which includes a plunger 704 movably arranged at the cantilever end. The end of the plunger 704 facing the rotating support 701 is a curved surface, and an elastic member (not shown in the figure) connected to the plunger 704 is provided on the cantilever end. A locking hole 705 for inserting the plunger 704 is provided on the rotating support 701. When the rotating support 701 is Figure 5 During the clockwise rotation from the first working state shown to the second working state, the side of the rotating support 701 facing the plunger 704 will press and push the curved end of the plunger 704, compressing the elastic member. When the locking hole 705 on the rotating support 701 rotates to a position relative to the curved end of the plunger 704, the plunger 704 will automatically be inserted into the locking hole 705 under the action of the elastic member. At this time, the position of the rotating support 701 is locked, and the loading and unloading gap is stably opened. When it is necessary to switch the rotating support 701 from the second working state to the first working state, it is only necessary to apply force to rotate the rotating support 701, so that the curved end of the plunger 704 is subjected to force, compressing the elastic member, and then continuing to rotate the rotating support 701 to move the plunger 704 away from the locking hole 705, releasing the plunger 704 from the locking hole 705.

[0049] For example Figure 4 and Figure 7As shown, in order to keep the bearing surface 201 in a horizontal state, the rotating support mechanism 7 further includes a first locking member, which includes a clamp 702 provided at the cantilever end and a lock 703 provided on the base 1 for cooperating with the clamp 702. When the rotating support 701 is in the first working state, that is, Figure 5 In the state shown, the clamp 702 and the lock 703 are locked. It should be noted that the first locking member is not limited to the connection between the clamp 702 and the lock 703, and can also be configured as other conventional configurations in the prior art, as long as it can lock and maintain the horizontal state of the receiving surface 201.

[0050] like Figure 7 As shown, during the rotation of the rotating support 701, in order to provide good limiting protection for the rotating support 701, a limiting bolt 12 can be set at the cantilever end, and at the same time, an arc groove is opened on the rotating support 701, and the arc groove is coaxially arranged with the virtual circle formed by the rotation of the rotating support 701. The limiting bolt 12 is placed on the arc groove, and during the rotation of the rotating support 701, the arc groove will be driven to rotate on the limiting bolt 12, thereby ensuring the stability of the rotation of the rotating support 701. At the same time, due to the presence of the limiting bolt 12, the rotation angle of the rotating support 701 can also be limited to prevent its rotation angle from being too large.

[0051] like Figure 3 As shown, further, in order to ensure that the barrel product will not be deformed or damaged after being pressed by the side pressure clamp 8, in some possible implementations, multiple auxiliary pads 11 will be added to the side of the cantilever structure to fill the gap between the barrel product and the side of the cantilever structure, so that when the barrel product is pressed laterally by the side pressure clamp 8, the auxiliary pads 11 can play a certain supporting role on the inner side of the barrel product. At the same time, in order to facilitate the smooth loading and unloading movement of the barrel product on the cantilever structure, a roller table consisting of multiple parallel assist rollers 10 can be provided on the base 1. The roller table is set in two groups and distributed below the cantilever structure. When the barrel product is loaded and unloaded, the roller table can assist in pushing the bottom of the barrel product, making its movement smooth and unstuck, thereby shortening the loading and unloading time.

[0052] The above describes an embodiment of the present invention in detail. However, the above content is only a preferred embodiment of the present invention and should not be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent application of the present invention.
