Detailed Implementation
[0031] To enable those skilled in the art to better understand the technical solutions of this utility model, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
[0032] like Figure 1 As shown, a welding fixture for a robotic welding workstation according to one embodiment of the present invention includes a first support rod 1 and a limiting component 2. When used on a welding platform, the first support rod 1 can be inserted into a positioning hole 8 on the platform 7. The limiting component 2 is sleeved on the outside of the first support rod 1. The limiting component 2 slides on the platform to adjust the depth of the first support rod 1 inserted into the positioning hole 8, thereby adjusting the length of the first support rod 1 exposed on the surface of the platform to adapt to the fixing of workpieces of different thicknesses. At the same time, the length of the exposed part of the first support rod 1 on the platform can be adjusted to the minimum value required, reducing the obstruction of the welding torch's movement space by the excess part.
[0033] like Figure 4 As shown, the limiting component 2 includes a limiting ring 21, a pair of springs 22 and a pair of limiting pins 23. The limiting ring 21 is sleeved on the outside of the first support rod 1 and can control the length of the first support rod 1 entering the positioning hole 8.
[0034] like Figure 9 As shown, the limiting ring 21 has a first cavity 212 that matches the limiting pin 23, and the limiting pin 23 slides inside the first cavity 212.
[0035] like Figure 8As shown, when the limiting pin 23 slides to the center of the limiting ring 21, the limiting pin 23 protrudes into the hole of the limiting ring 21, a limiting hole 102 is arranged on the side wall of the first supporting rod 1, the limiting pin 23 matches the limiting hole 102, at this time, the limiting pin 23 is clamped in the limiting hole 102, thereby preventing the first supporting rod 1 from sliding inside the limiting assembly 2, and further fixing the limiting assembly 2 at a specified position of the first supporting rod 1.
[0036] As shown in the figure, Figure 7 The limiting pin 23 includes a limiting column 231, which is a cylinder and can be clamped in the limiting hole 102 from inside the first cavity 212. A sliding block 232 is integrally formed on one side of the limiting column 231, which is a hollow cylindrical shell. A pair of first limiting blocks 211 are welded on the opposite end faces of the limiting ring 21, and are located at the opening of the first cavity 212, which can prevent the sliding block 232 from sliding out of the first cavity 212.
[0037] A sliding groove 233 matching the first limiting block 211 is arranged on the sliding block 232, the first limiting block 211 passes through the sliding groove 233, and the first limiting block 211 can clamp the sliding block 232 to prevent the sliding block 232 from rotating. A spring 22 is placed in the shell of the sliding block 232, one end of the spring 22 abuts against the shell of the sliding block 232, and the other end of the spring 22 abuts against one side of the first limiting block 211. Under the action of the spring 22, one side of the sliding groove 233 abuts against the first limiting block 211, and one side of the sliding block 232 abuts against the side wall of the first cavity 212. At this time, the limiting column 231 protrudes from the limiting ring 21, and the limiting column 231 is clamped in the limiting hole 102, thereby preventing the first supporting rod 1 from sliding inside the limiting assembly 2, and further fixing the limiting assembly 2 at a specified position of the first supporting rod 1.
[0038] One side of the sliding block 232 is fixedly connected with a ring 234, which is located on both sides of the limiting ring 21. When it is necessary to adjust the length of the first supporting rod 1, two fingers are inserted into the ring 234 respectively, and the sliding block 232 is pulled outwards by force, compressing the spring 22, and the sliding block 232 drives the limiting column 231 to retract into the first cavity 212. At this time, the limiting column 231 is no longer clamped in the limiting hole 102, and the limiting assembly 2 can slide freely in the first supporting rod 1. After adjusting to the appropriate position, the fingers are released, and under the action of the spring 22, the limiting column 231 slides out of the first cavity 212 and is clamped in the limiting hole 102 again, and the position of the limiting assembly 2 is fixed again.
[0039] As shown in the figure, Figure 2As shown, the side end of the first supporting rod 1 is a sleeve, and the second supporting rod 3 is slidably connected in the sleeve, and the length of the second supporting rod 3 sliding out of the sleeve is determined according to the requirement. The side end of the second supporting rod 3 is also a sleeve, and the third supporting rod 4 is threadedly connected in the sleeve. When the third supporting rod 4 is threadedly rotated in the sleeve, the length of the third supporting rod 4 extending out of the sleeve can be adjusted, and then the third supporting rod 4 is abutted against the workpiece to fix the workpiece. The side end of the third supporting rod 4 is clamped with the handle 5, and the handle 5 is rotated to drive the third supporting rod 4 to rotate. After the third supporting rod 4 is rotated to the position and abutted against the workpiece, the handle 5 can be removed and inserted into the positioning hole 8 to reduce the space occupied by the clamp and provide more welding space.
[0040] As shown in the drawings, Figure 4 The handle 5 includes the handle first section 501, and the second limiting block 508 is integrally formed on the side end face of the handle first section 501. The side end of the third supporting rod 4 is provided with the first limiting slot 401 matched with the second limiting block 508, and the second limiting block 508 can be inserted into the slot wall of the first limiting slot 401 to realize the rotation of the handle 5 to drive the third supporting rod 4 to rotate. The side end face of the second limiting block 508 is provided with a sharp head with a certain length, and the second limiting block 508 can be used as a shovel to remove the welding bumps on the workpiece when the handle 5 is removed.
[0041] As shown in the drawings, Figure 5 The side end face of the handle first section 501 is integrally formed with the third limiting block 509 perpendicular to the second limiting block 508, and the length of the third limiting block 509 is much smaller than that of the second limiting block 508. The side end face of the third supporting rod 4 is provided with the second limiting slot 402 matched with the third limiting block 509. When the second limiting block 508 is inserted into the slot wall of the first limiting slot 401, the third limiting block 509 is also inserted into the slot wall of the second limiting slot 402. At this time, the central axis of the third supporting rod 4 and the handle 5 is on the same straight line, and the third limiting block 509 can increase the stability of the insertion of the handle 5 and the third supporting rod, and prevent the handle 5 from being tilted.
[0042] The other side end face of the handle first section 501 is integrally formed with the handle second section 502, and the handle second section 502 is a cylinder with the same diameter as the hole diameter of the positioning hole 8. The handle second section 502 can be inserted into the positioning hole 8, and the handle 5 can be kept in the vertical fixed state when the handle 5 is removed from the third supporting rod 4 and inserted into the positioning hole 8. At this time, the handle 5 can be used as a clamp abutting against the workpiece.
[0043] The side end face of the handle second section 502 is integrally formed with the handle third section 503, and the handle third section 503 is a cylinder with a square bottom surface. When the handle 5 is used as a clamp, the side face of the handle third section 503 is a plane, which can increase the contact area with the workpiece and fix the workpiece more stably.
[0044] The third section 503 of the handle is integrally formed with a fourth section 504 of the handle, and the fourth section 504 of the handle is provided with a first through hole 505. When the handle 5 is removed from the third supporting rod 4, the handle 5 can be hung on the hook through the first through hole 505, so as to facilitate the storage of the handle 5.
[0045] The fourth section 504 of the handle is sleeved with a handle sleeve 507 made of plastic, which is more comfortable to hold and can increase the friction force, so that the handle 5 is easier to rotate. Since the handle sleeve 507 is sleeved on the fourth section 504 of the handle, it is more convenient to replace the handle sleeve 507 when it is worn out.
[0046] As shown in Figure 1 the other end of the second supporting rod 3 is threadedly connected with a movable supporting rod 6, and the side end surface of the second supporting rod 3 is provided with a second internal thread 301. The side end surface of the movable supporting rod 6 is integrally formed with a threaded column 601 matched with the second internal thread 301. The threaded column 601 can be screw-connected in the second supporting rod 3, so as to fix the movable supporting rod 6 and the second supporting rod 3 together. When the second supporting rod 3 needs not to be long in length, the movable supporting rod 6 can be removed to reduce the occupied space of the clamp and increase the welding space of the welding gun. When the second supporting rod 3 needs to be longer, the movable supporting rod 6 is screw-fixed on the second supporting rod 3 as an extension of the second supporting rod 3, which is equivalent to increasing the length of the second supporting rod 3.
[0047] As shown in Figure 6 the side end surface of the first supporting rod 1 is provided with a first internal thread 101 matched with the threaded column 601. The threaded column 601 can be screw-connected in the first internal thread 101, so as to fix the movable supporting rod 6 and the first supporting rod 1 together. At this time, the movable supporting rod 6 is used as an extension of the first supporting rod 1, which is equivalent to increasing the length of the first supporting rod 1, so as to make the clamp applicable to workpieces in a larger thickness range.
[0048] The side end surface of the fourth section 504 of the handle is provided with a third internal thread 506 matched with the threaded column 601. The threaded column 601 can be screw-connected in the third internal thread 506. When the movable supporting rod 6 is not used as an extension, the movable supporting rod 6 can be screw-connected on the handle 5, so as to store the movable supporting rod 6 and prevent it from being lost.
[0049] In use, as shown in Figure 2The handle 5 is inserted into the third supporting rod 4, the handle 5 is rotated to drive the third supporting rod 4 to rotate, the third supporting rod 4 is firmly abutted with the workpiece, then the handle 5 is removed, the space occupied by the clamp can be reduced, and a larger welding space is provided. At this time, the handle 5 is fixed on the hook through the first through hole 505, the handle 5 is stored, and loss is prevented; or the handle 5 is inserted into the positioning hole 8 and used as a clamp; or the handle 5 is used as a shovel to remove the welding bumps on the surface of the workpiece.
[0050] When the length of the second supporting rod 3 is sufficient for use, the movable supporting rod 6 is removed and is screwed on the handle 5, so that the space occupied by the clamp is reduced; when the length of the second supporting rod 3 is insufficient for use, the movable supporting rod 6 is screwed on the second supporting rod 3 and is used as an extension of the second supporting rod 3, so that the application range of the clamp is increased.
[0051] When the exposed part of the first supporting rod 1 needs to be short, the position of the limiting assembly 2 on the first supporting rod 1 can be adjusted, so that the exposed part of the first supporting rod 1 is reduced, and the space occupied by the clamp is reduced; when the exposed part of the first supporting rod 1 needs to be more, the limiting assembly 2 can be adjusted to the appropriate position of the first supporting rod 1, or the movable supporting rod 6 is screwed on the first supporting rod 1 at the same time, so that the application range of the clamp is increased, the number of types of required clamps is reduced, and the cost is saved.
