Description

Technical Field

[0001] This utility model relates to the field of welding tool technology, and in particular to a lifting support frame. Background Technology

[0002] When welding products with rigid and flexible joints, an external support frame is needed to adjust the product height. The head of the product lacks positioning, which is inconvenient for production operations. Therefore, positioning fixtures are needed to fix the head and tail of the product, typically supported by a support frame.

[0003] However, different products have different sizes, and the height of the graphite varies when the product is welded to the graphite. This means that the existing support frame can only handle a single product model. When switching between different products, a single support frame and positioning fixture cannot guarantee the positioning and welding dimensions of the front end of the product, so the support frame and positioning fixture must be replaced accordingly.

[0004] Therefore, there is an urgent need for a lifting support frame to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a lifting support frame to solve the technical problem of poor versatility of support frames in the prior art.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0010] The lifting mechanism includes locking components and a lifting column;

[0011] One of the base and the fixed platform is provided with the locking element, and the other is provided with the lifting column, which passes through the locking element;

[0012] The locking element has a locked state and an unlocked state. When the locking element is in the locked state, the lifting column is fixed to the locking element. When the locking element is in the unlocked state, the lifting column is separated from the lifting column.

[0013] Preferably, the placement portion of the fixed platform has multiple placement holes.

[0014] Preferably, the locking element is fixedly connected to the base, one end of the lifting column is fixedly connected to the fixed platform, and the other end passes through the base.

[0015] Preferably, the base has a mounting hole, and the locking member is at least partially located in the mounting hole.

[0016] Preferably, the locking member is provided with an operating handle, which is configured to switch the locking member from a locked state to an unlocked state or from an unlocked state to a locked state.

[0017] Preferably, multiple locking elements and lifting columns are provided, with at least two lifting columns having the locking element.

[0018] Preferably, at least one locking element is provided on each side of the placement portion.

[0019] Preferably, the base is provided with a horizontally protruding fixing protrusion, and the fixing protrusion is provided with fixing holes, through which screws pass to fix the base to the mounting surface.

[0020] Preferably, the fixed platform has an avoidance notch on the side opposite to the fixed protrusion.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0036] like Figures 1 to 3As shown, this embodiment discloses a lifting support frame. The lifting support frame includes a base 1, a fixed platform 2, and a lifting mechanism 3. A placement part 21 is provided on the fixed platform 2, configured to place a positioning fixture. The lifting mechanism 3 includes a locking member 31 and a lifting column 32. One of the base 1 and the fixed platform 2 is provided with the locking member 31, and the other is provided with the lifting column 32, which passes through the locking member 31. The locking member 31 has a locked state and an unlocked state. When the locking member 31 is in the locked state, the lifting column 32 is fixed to the locking member 31. When the locking member 31 is in the unlocked state, the lifting column 32 is separated from the locking member 31.

[0037] It is understood that the lifting support frame proposed in this embodiment, by setting a base 1, a fixed platform 2 and a lifting mechanism 3, the fixed platform 2 is provided with a placement part 21 for placing positioning fixtures. The locking member 31 in the lifting mechanism 3 switches between locked and unlocked states to lock or unlock the position of the fixed platform 2. Then, through the lifting column 32 in the lifting mechanism 3, the fixed platform 2 can be raised and lowered relative to the base 1, thereby adjusting the height position of the fixed platform 2. This makes the adjustment of the lifting support frame quick and simple, and the lifting support frame can be used for positioning fixtures of different products, improving the versatility of the lifting support frame.

[0038] Furthermore, in order to better fix different positioning fixtures, in some embodiments, the placement part 21 of the fixing platform 2 is provided with multiple placement holes 211.

[0039] Specifically, such as Figure 2 As shown, in this embodiment, the placement portion 21 of the fixed platform 2 has an array of placement holes 211, which penetrate the placement portion 21 of the fixed platform 2. It can be understood that through the array of placement holes 211, positioning fixtures for different products can be installed on the fixed platform 2. Moreover, the installation and replacement of the fixed platform 2 are convenient and simple, improving work efficiency. For example, the bottom of the positioning fixture is provided with multiple protrusions that mate with the placement holes 211, and the positioning fixture is fixed by the interference fit between the protrusions and the placement holes 211.

[0040] Of course, in some other embodiments, the positioning fixtures of different products are provided with fixing holes 121, and bolts pass through the fixing holes 121 and the placement holes 211 in sequence and are threadedly connected to the nuts to fix the positioning fixtures on the fixed platform 2.

[0041] Furthermore, such as Figure 3As shown, in this embodiment, the locking member 31 is fixedly connected to the base 1, and one end of the lifting column 32 is fixedly connected to the fixed platform 2, while the other end passes through the base 1. Exemplarily, the fixed platform 2 has a countersunk hole, through which a screw passes and connects to one end of the lifting column 32. The base 1 has a lifting hole, through which the other end of the lifting column 32 passes, and the locking member 31 is fixedly connected to the base 1 by bolts. It can be understood that after changing the positioning fixture for different products, the locking member 31 is first switched to the unlocked state, then the fixed platform 2 is pulled or pushed to slide along with the lifting column 32 within the lifting hole. When the positioning fixture is at a suitable working height, the locking member 31 is switched to the locked state, thus fixing the position of the fixed platform 2 relative to the base 1.

[0042] In some embodiments, the base 1 has a mounting hole 11, and the locking member 31 is at least partially located in the mounting hole 11. It is understood that by placing the locking member 31 at least partially in the mounting hole 11, the contact area between the locking member 31 and the base 1 can be increased, the firmness of the locking member 31 can be improved, and the sliding of the lifting column 32 can be more stable.

[0043] Specifically, such as Figure 3 and Figure 4 As shown, in this embodiment, the lifting hole is the mounting hole 11. The locking member 31 includes a large-diameter section 312 and a small-diameter section 313. The small-diameter section 313 is located inside the hole, and its outer wall abuts against the inner diameter of the mounting hole 11. The large-diameter section 312 is fixedly connected to the base 1 by bolts. This arrangement facilitates the positioning of the locking member 31 on the base 1 during installation, and also makes the small-diameter section 313 of the locking member 31 more stable, providing stable guidance for the sliding of the lifting column 32.

[0044] Furthermore, the length of the small diameter section 313 of the locking member 31 is greater than the thickness of the base 1. It can be understood that after the locking member 31 is installed in the mounting hole 11, the end of the small diameter section 313 away from the large diameter section 312 can extend out of the base 1 away from the fixed platform 2. This setting can increase the contact area between the locking member 31 and the lifting column 32 and improve the fixing effect of the locking member 31 on the lifting column 32.

[0045] Furthermore, in some embodiments, the locking member 31 is provided with an operating handle 311, which is configured to switch the locking member 31 from a locked state to an unlocked state or from an unlocked state to a locked state. It is understood that the operating handle 311 can rotate on the locking member 31, and the state of the locking member 31 can be switched by rotating the operating handle 311.

[0046] Specifically, in this embodiment, when the operating handle 311 is rotated to be perpendicular to the axis of the lifting column 32, the operating handle 311 can abut against the lifting column 32, thereby fixing the lifting column 32 and thus fixing the fixed platform 2. When the operating handle 311 is rotated to be parallel to the axis of the lifting column 32, the operating handle 311 can separate from the lifting column 32, and the lifting column 32 can slide up and down, thereby adjusting the position of the fixed platform 2.

[0047] Furthermore, in some embodiments, the lifting support frame includes multiple locking elements 31 and lifting columns 32, with at least two lifting columns 32 having locking elements 31. It is understood that increasing the number of locking elements 31 and lifting columns 32 improves the fixing effect on the lifting columns 32, ensuring that the locking elements 31 stably fix the lifting columns 32. This ensures that when the locking elements 31 are in the locked state, the fixed platform 2 will not fall due to insecure fixing of the lifting columns 32 by the locking elements 31.

[0048] Furthermore, in some embodiments, to further improve the fixing effect of the locking member 31 on the lifting column 32, at least one locking member 31 is provided on each side of the placement part 21. It is understood that by providing locking members 31 on both sides of the placement part 21 to fix the lifting column 32, the fixing platform 2 is more balanced, which is beneficial to the stability of the fixing platform 2.

[0049] For example, in this embodiment, two lifting columns 32 are provided, located on opposite sides of the placement portion 21 on the fixed platform 2. Two locking members 31 are also fixedly installed on the base 1, each corresponding to one lifting column 32. The operating handles 311 on the two locking members 31 are arranged symmetrically at the center. This arrangement ensures that the operating handles 311 on both sides of the locking members 31 rotate in the same direction, reducing the probability of operator error and further ensuring the stability of the fixed platform 2 in the fixed position.

[0050] Furthermore, in some embodiments, the base 1 is provided with a horizontally protruding fixing protrusion 12, and a fixing hole 121 is provided on the fixing protrusion 12. Screws pass through the fixing hole 121 of the base 1 and are fixed to the mounting surface. It can be understood that this arrangement can reduce the size of the base 1, facilitate the installation of the base 1, and still maintain a good fixation of the base 1.

[0051] Specifically, in this embodiment, such as Figure 2As shown, fixing protrusions 12 are provided at both ends of the same side of the base 1. This arrangement can fix the base 1 and provide better anti-overturning torque, improve the connection stability between the base 1 and the mounting plane, make the base 1 more firmly fixed, and ensure that the fixed platform 2 will not shake during use due to the base 1 not being firmly fixed.

[0052] Furthermore, in some embodiments, such as Figure 1 and Figure 2 As shown, the fixed platform 2 has a clearance notch 22 on the side opposite to the fixed protrusion 12. It is understood that some positioning fixtures are relatively large. In order to facilitate the installation of the large positioning fixtures onto the fixed platform 2 so that they can fix the product, the fixed platform 2 has a clearance notch 22. The installation of the large positioning fixtures is achieved through the clearance notch 22.

[0053] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
