Description

Technical Field

[0001] This utility model relates to the field of sheet metal processing technology, specifically to an alignment and positioning device for welding titanium metal sheets. Background Technology

[0002] Titanium, as an important high-performance material, is widely used in aerospace, shipbuilding, chemical equipment and high-end consumer products due to its excellent properties such as high strength, good corrosion resistance and light weight. According to CN211804567U, a positioning and clamping device for an automatic plate welding equipment is disclosed. This technology discloses a technical solution including a welding plate, support columns arranged around the bottom of the welding plate, a collection box arranged on one side of the support columns, a clamping device arranged on one side of the top of the welding plate, and an adjustment device arranged at one end of the clamping device. It has the technical effect of "the first telescopic pump, telescopic rod, sliding plate, pushing groove plate, and sliding groove are provided to facilitate the placement of the plate on the placement groove in the positioning plate when welding the plate. The first telescopic pump extends and retracts the telescopic rod, causing the sliding plate on the surface of the telescopic rod to move in the sliding groove. The pushing groove plate is used to fix the plate. Then, the plates are moved together according to the size of the plate for welding, which can increase the stability of the plate during welding, facilitate movement according to the size of the plate, and facilitate fixing according to the size of the plate". The above solution places the plate directly on a flat processing table for positioning. Although it provides support, the huge table completely blocks the path of the welding torch to approach the weld from the bottom or side of the plate. This means that when welding the bottom of the workpiece is required (such as completing the bottom sealing weld or overhead welding of key components), the operation must be interrupted and the entire workpiece must be flipped over. This greatly reduces the efficiency of the operation. Moreover, the flipping process can easily damage the completed front weld or cause the precisely positioned workpiece to become misaligned, which seriously affects the stability and consistency of the welding quality. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides an alignment and positioning device for welding titanium metal plates. It uses a multi-directional pull-out support rod to quickly adapt to different plate sizes and weld directions, and employs a push-and-spin lock mechanism to ensure stable positioning, thereby improving the efficiency and accuracy of welding.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an alignment and positioning device for welding titanium metal sheets, comprising a base and a sheet workpiece, wherein a positioning mechanism is provided on the base for aligning and positioning the sheet workpiece, the positioning mechanism comprising: An adjustment component, mounted on the base, is used to adjust the dimensions of the sheet metal workpiece. The support assembly includes a support base mounted on the adjustment assembly. An extension rod is slidably installed inside the support base, extending through the left and right sides and through the front and back sides. Several locking holes are arranged in an array on the outer wall of the extension rod. A connecting seat is fixed to the end of the extension rod. An extension platform is fixed to the upper end of the connecting seat. A handle is fixed to the end of the extension rod away from the connecting seat. A locking assembly is mounted on the support and is used to secure the extension rod.

[0005] Preferably, the locking assembly includes a mounting base fixed to the front end and right outer wall of the support base. A locking pin is slidably installed inside the mounting base and cooperates with the locking hole. A knob is fixed to the outer end of the locking pin. An axially arranged straight groove is opened on the outer wall of the locking pin. An annular groove is opened on the locking pin and communicates with the straight groove. A positioning pin is fixed to the upper end inside the mounting base and limits the locking pin.

[0006] Preferably, the support assembly further includes a right-angle baffle fixed to the upper edge of the support base, and the inner wall of the right-angle baffle has a groove at a right angle.

[0007] Preferably, a support platform is fixed to the upper end of the support base, and the top height of the support platform is flush with the top height of the extension platform.

[0008] Preferably, the adjustment assembly includes a length adjustment screw slide mounted on the upper end of the base, a first width adjustment screw slide fixed to the rear end of the length adjustment screw slide, a second width adjustment screw slide mounted on the slider of the length adjustment screw slide, and a support seat mounted on the left end of the second width adjustment screw slide and the slider of the second width adjustment screw slide.

[0009] Preferably, both the top surface of the extension platform and the top surface of the support platform are provided with anti-slip textures.

[0010] Beneficial effects This invention provides an alignment and positioning device for welding titanium metal sheets. Compared with the prior art, it has the following advantages: 1. The support base itself is machined into a hollow structure, and slides that precisely match the size of the extension rod are cut through the walls on its left, right, front, and rear sides. This key structural feature allows the operator to freely choose to insert and slide the extension rod from any pair of directions—left or right, front or rear—of the support base, depending on the placement of the sheet metal workpiece and the specific position of the required support edge in the actual welding process. The extension rod and its end-fixed extension platform can be manually configured to the most needed direction by hand, parallel to the weld seam to provide edge support, enhancing versatility and on-site strain efficiency.

[0011] 2. When locking is required, the operator pushes the knob inward to slide the locking pin along the mounting base, so that the front end of the locking pin is precisely inserted into the corresponding lock hole on the extension rod. At this time, continue to rotate the knob, so that the positioning pin fixed inside the mounting base slides from the axial straight groove on the outer wall of the locking pin into the annular groove that communicates with it. Due to the radial constraint of the annular groove, the positioning pin will be locked in the annular groove, thereby effectively preventing the locking pin from coming out of the lock hole when the equipment vibrates or is accidentally touched, forming a reliable double insurance. When unlocking is required, simply rotate the knob in the opposite direction to align the straight groove with the positioning pin, and manually push the locking pin back to its original position, improving the locking efficiency and safety after adjusting the extension rod.

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1 - Figure 6This utility model provides a technical solution: an alignment and positioning device for welding titanium metal plates, including a base 1 and a plate workpiece 3. The base 1 is provided with a positioning mechanism 2 for aligning and positioning the plate workpiece 3. The positioning mechanism 2 includes: Adjustment component 21 is mounted on base 1 and is used to adjust the specifications of sheet metal workpiece 3; The support assembly 22 includes a support base 221 disposed on the adjustment assembly 21. An extension rod 222 is slidably installed inside the support base 221, passing through the left and right sides and the front and back sides. The outer wall of the extension rod 222 has a plurality of lock holes 223 arranged in an array. A connecting seat 224 is fixed to the end of the extension rod 222. An extension platform 225 is fixed to the upper end of the connecting seat 224. A handle 226 is fixed to the end of the extension rod 222 away from the connecting seat 224. Locking assembly 23 is mounted on support base 221 and is used to fix extension rod 222.

[0016] In this embodiment, the support base 221 itself is machined into a hollow structure, and slides that precisely match the size of the extension rod 222 are opened through the walls on its left, right and front sides and front and rear sides. This key structural feature allows the operator to freely choose to insert and slide the extension rod 222 from any pair of directions, such as the left or right, front or rear side of the support base 221, according to the placement direction of the plate workpiece 3 in the actual welding process and the specific position of the required support edge. The extension rod 222 and the extension platform 225 fixed to its end can be quickly configured to the most needed direction by manually using the handle 226, so as to provide edge support parallel to the weld, thereby enhancing versatility and on-site strain efficiency.

[0017] Specifically, the locking assembly 23 includes a mounting base 231 fixed to the front end and right outer wall of the support base 221. A locking pin 232 is slidably mounted inside the mounting base 231 and cooperates with the lock hole 223. A knob 233 is fixed to the outer end of the locking pin 232. An axially arranged straight groove 234 is opened on the outer wall of the locking pin 232. An annular groove 235 is opened on the locking pin 232 and communicates with the straight groove 234. A positioning pin 236 is fixed to the upper end inside the mounting base 231 and limits the locking pin 232.

[0018] In this embodiment, when locking is required, the operator pushes the knob 233 inward to cause the locking pin 232 to slide along the mounting base 231, so that the front end of the locking pin 232 is precisely inserted into the corresponding locking hole 223 on the extension rod 222. At this time, the knob 233 is rotated again, so that the positioning pin 236 fixed inside the mounting base 231 slides from the axial straight groove 234 on the outer wall of the locking pin 232 into the annular groove 235 that communicates with it. Due to the radial constraint of the annular groove 235, the positioning pin 236 will be stuck in the annular groove 235, thereby effectively preventing the locking pin 232 from coming out of the locking hole 223 when the equipment vibrates or is accidentally touched, forming a reliable double insurance. When unlocking is required, the knob 233 is rotated in the opposite direction to align the straight groove 234 with the positioning pin 236, and the locking pin 232 can be pushed back to its original position by manual external force, improving the locking efficiency and safety after adjusting the extension rod 222.

[0019] Specifically, the support assembly 22 also includes a right-angle baffle 227 fixed to the upper edge of the support base 221, and the inner wall of the right-angle baffle 227 has a right-angle groove.

[0020] In this embodiment, a standard rectangular coordinate system is formed by the two mutually perpendicular inner wall surfaces of the right-angle baffle 227. During operation, it is only necessary to press the two adjacent sides of the plate workpiece 3 tightly against the right-angle surface to quickly achieve accurate two-dimensional positioning.

[0021] Specifically, a support platform 228 is fixed to the upper end of the support base 221, and the top height of the support platform 228 is flush with the top height of the extension platform 225.

[0022] In this embodiment, the sheet metal workpiece 3 can obtain complete and uniform bottom support regardless of the extension position of the extension platform 225.

[0023] Specifically, the adjustment assembly 21 includes a length adjustment screw slide 211 mounted on the upper end of the base 1, a first width adjustment screw slide 212 fixed to the rear end of the length adjustment screw slide 211, a second width adjustment screw slide 213 mounted on the slider of the length adjustment screw slide 211, and a support seat 221 mounted on the left end of the second width adjustment screw slide 213 and the slider of the second width adjustment screw slide 213.

[0024] In this embodiment, the two support seats 221 can be synchronously and precisely displaced in the longitudinal direction by adjusting the component 21, and the lateral relative distance between the two support seats 221 can be adjusted independently. The entire support system can also be laterally offset and adjusted by the first width adjusting screw slide 212, thereby providing positioning for titanium metal sheet workpieces 3 of different sizes and different docking forms.

[0025] Specifically, the top surface of the extension platform 225 and the top surface of the support platform 228 are both provided with anti-slip textures.

[0026] The working principle and usage process of this utility model are as follows: First, the support base 221 itself is processed into a hollow structure, and slides that precisely match the size of the extension rod 222 are opened through the walls on its left, right and front sides and front and rear sides. This key structural feature allows the operator to freely choose to insert and slide the extension rod 222 from any pair of directions, such as the left or right side, front or rear side of the support base 221, according to the placement direction of the plate workpiece 3 in the actual welding process and the specific position of the required support edge. The extension rod 222 and the extension platform 225 fixed to its end can be quickly configured to the most needed direction by manually using the handle 226 to provide edge support parallel to the weld. Then, when locking is required, the operator pushes the knob 233 inward to make the locking pin 232 slide along the mounting base 231, so that the front end of the locking pin 232 is precisely inserted into the corresponding locking hole 223 on the extension rod 222. At this time, the knob 233 is rotated again, so that the positioning pin 236 fixed inside the mounting base 231 slides from the axial straight groove 234 on the outer wall of the locking pin 232 into the annular groove 235 that communicates with it. Due to the radial constraint of the annular groove 235, the positioning pin 236 will be stuck in the annular groove 235, thereby effectively preventing the locking pin 232 from coming out of the locking hole 223 when the equipment vibrates or is accidentally touched, forming a reliable double insurance. When unlocking is required, simply rotate the knob 233 in the opposite direction to make the straight groove 234 align with the positioning pin 236, and the locking pin 232 can be pushed back to its original position by manual external force, improving the locking efficiency and safety after adjusting the extension rod 222. Finally, by adjusting component 21, the two support seats 221 can be synchronously and precisely displaced in the longitudinal direction, and the lateral relative distance between the two support seats 221 can be adjusted independently. The entire support system can also be laterally offset and adjusted by the first width adjusting screw slide 212, thereby providing positioning for titanium metal sheet workpieces 3 of different sizes and different docking forms.
