[0002] The welded structures of bus frames commonly include rectangular, U-shaped, L-shaped, trapezoidal, and triangular structures. The smallest unit in these structures is a profile, L-shaped component, or U-shaped component. Traditionally, the process of assembling the frame using these smallest units involves welding positioning blocks to corresponding positions on a positioning fixture according to the desired frame shape. However, this type of positioning fixture has limited versatility; different positioning fixtures need to be prefabricated for use with frames of different planar shapes and sizes, resulting in high overall manufacturing costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide an adjustable welding positioning device that does not require frequent model changes, is compatible with various planar shapes and various sizes of skeleton splicing structures, and has higher versatility and flexibility.

[0004] The present invention includes a positioning base plate, a first positioning block, and positioning modules. The positioning base plate is provided with a first sliding groove and a second sliding groove, which are intersecting and perpendicular to each other. The first positioning block is disposed between the edge of the positioning base plate and one side of the first sliding groove. There are several positioning modules, which are correspondingly disposed in the first or second sliding groove and can all move along the intersection of the first and second sliding grooves. Each positioning module is provided with a locking structure for fixing the position of the positioning module.

[0005] Furthermore, the positioning module includes a second positioning block, a screw, and a locking block. The width of the second positioning block and the locking block is greater than the width of the first slide groove and the second slide groove. The second positioning block is rotatably mounted on the upper end of the screw. The first slide groove and the second slide groove are both through grooves. The lower end of the screw passes through the first slide groove or the second slide groove and is threadedly connected to the locking block located below the positioning base plate.

[0007] Furthermore, the positioning module also includes a handle, which is disposed at the top of the upper end of the screw.

[0008] Furthermore, one end of the handle is arc-shaped, and the arc-shaped end of the handle is hinged to the top of the upper end of the screw. The axis of the hinge is set radially along the screw and eccentrically at the arc-shaped end of the handle.

[0009] Furthermore, it also includes a supporting base plate, wherein the positioning base plate is mounted above the supporting base plate by a support member, and the bottom surface of the positioning base plate is spaced apart from the top surface of the supporting base plate.

[0010] Furthermore, the support member consists of several locking pins, and both the positioning base plate and the support base plate are provided with several slots.

[0024] like Figures 1-8 As shown, this utility model provides an adjustable welding positioning device, including a positioning base plate 1, a first positioning block 2, and positioning modules 3. The positioning base plate 1 is provided with a first sliding groove 11 and a second sliding groove 12, which are intersecting and perpendicular to each other. The first positioning block 2 is located between the edge of the positioning base plate 1 and one side of the first sliding groove 11, and the end of the second sliding groove 12 extends between the first positioning block 2 and the first sliding groove 11. Several positioning modules 3 are provided, correspondingly positioned within either the first sliding groove 11 or the second sliding groove 12. All positioning modules 3 can move along the intersection of the first and second sliding grooves 11 and 12 within the first and second sliding grooves 11, i.e., each positioning module 3 is slidably positioned within either the first or second sliding groove 12. A positioning module 3 located in the first sliding groove 11 can move into the second sliding groove 12 along the intersection of the first and second sliding grooves 11, and vice versa. Each of the positioning modules 3 is equipped with a locking structure to fix its current position when it moves to the corresponding position within the first slide groove 11 or the second slide groove 12. Preferably, there are three or more positioning modules 3.

[0025] When this utility model is used, Figure 7Taking the rectangular skeleton 100 shown as an example, move two positioning modules 3 into the first slide groove 11 adjacent to the first positioning block 2, and position the two positioning modules 3 at both ends of the first slide groove 11. Then move another positioning module 3 into the second slide groove 12. The first positioning block 2 limits one side of the splicing structure of the rectangular skeleton 100. Then, the two positioning modules 3 in the first slide groove 11 limit the other two sides of the splicing structure of the rectangular skeleton 100. Finally, the positioning module 3 in the second slide groove 12 limits the last side of the splicing structure of the rectangular skeleton 100. Figure 8 The positioning method for the trapezoidal skeleton 200 is similar. When used to position a U-shaped skeleton, the positioning modules 3 within the first positioning block 2 and the second slide groove 12 limit the lateral side of the U-shaped skeleton splicing structure in two directions. Then, the corresponding number of positioning modules 3 within the first slide groove 11 limit the vertical sides of the U-shaped skeleton splicing structure. The positioning method for other planar skeleton splicing structures is similar; simply move the positioning modules 3 to the corresponding positions to limit the corresponding sides of the skeleton splicing structure.

[0026] Based on the above, this utility model can be applied to the welding of various planar shape skeletons, such as rectangular skeleton 100, L-shaped skeleton, trapezoidal skeleton 200 and triangular skeleton. The welding positioning of different planar shape skeleton splicing structures can be achieved simply by moving the corresponding number of positioning modules 3 to the corresponding positions and fixing them in the first slide groove 11 and the second slide groove 12. Moreover, by moving the positioning modules 3, it can also be compatible with various planar shape skeleton splicing structures within a certain size range. Therefore, a single positioning device can be compatible with multiple planar shapes and multiple sizes of skeleton splicing structures, thereby realizing the welding positioning of different planar shapes and different sizes of skeleton splicing structures. It has higher versatility and flexibility of use, does not require frequent model changes, and has a lower total manufacturing cost.

[0027] The positioning module 3 includes a second positioning block 31, a screw 32, and a locking block 33. The widths of the second positioning block 31 and the locking block 33 are both greater than the widths of the first slide groove 11 and the second slide groove 12. The second positioning block 31 is rotatably mounted on the upper end of the screw 32, meaning that the second positioning block 31 can rotate relative to the screw 32. The first slide groove 11 and the second slide groove 12 are both through grooves. The second positioning block 31 is located on the top surface of the positioning base plate 1. The lower end of the screw 32 passes through the first slide groove 11 or the second slide groove 12 and is threadedly connected to the locking block 33 located below the positioning base plate 1.

[0028] The positioning module 3 has a simple overall structure, is easy to manufacture, and its movement and locking operations are convenient and quick. Specifically, the positioning module 3 uses a second positioning block 31 to limit the frame assembly structure. The second positioning block 31, screw 32, and locking block 33 form an I-shaped structure. Rotating the screw 32 increases the distance between the second positioning block 31 and the locking block 33, allowing the positioning module 3 to move. After moving the positioning module 3 to the corresponding position, rotating the screw 32 decreases the distance between the second positioning block 31 and the locking block 33, causing the second positioning block 31 and locking block 33 to clamp the positioning base plate 1, thus fixing the current position of the positioning module 3. The screw 32 and locking block 33 together form the locking structure of the positioning module 3. Since the second positioning block 31 can rotate relative to the screw 32, when one side of the frame assembly structure to be limited by the positioning module 3 is tilted, the second positioning block 31 can be rotated to align with the tilted side of the frame assembly structure. Figure 8 As shown.

[0029] The locking block 33 has a guide pin 331 on its top. The guide pin 331 passes through the first slide groove 11 or the second slide groove 12, and a threaded hole is formed on its top. The lower end of the screw 32 is threadedly connected to the threaded hole. The guide pin 331 has a rectangular cross-section. After passing through the first slide groove 11 or the second slide groove 12, it facilitates the movement of the positioning module 3 within the first slide groove 11 or the second slide groove 12, and also restricts the locking block 33 from rotating with the screw 32, ensuring the reliability of adjusting the distance between the second positioning block 31 and the locking block 33 by rotating the screw 32. The aforementioned threaded hole can pass through the locking block 33, for example... Figure 4 As shown, the threaded hole may be provided only on the guide sliding limit post 331, and the specific machining can be carried out according to actual needs.

[0030] The positioning module 3 also includes a handle 34, which is located at the top of the upper end of the screw 32 to facilitate rotation of the screw 32.

[0031] In one embodiment of this utility model, the handle 34 is fixedly disposed at the top of the upper end of the screw 32. In a preferred embodiment of this utility model, as... Figure 3 and Figure 4As shown, one end of the handle 34 is arc-shaped, and the arc-shaped end of the handle 34 is hinged to the top of the upper end of the screw 32. The axis of the hinge is arranged radially along the screw 32, and the axis of the hinge is eccentrically arranged at the arc-shaped end of the handle 34, that is, off-center from the center of the arc at the arc-shaped end of the handle 34. In this preferred embodiment, since the handle 34 is hinged radially along the screw 32, the screw 32 can still be rotated through the handle 34. Based on the eccentric arrangement of the hinge axis, after the positioning module 3 is moved to the corresponding position, when the handle 34 is pressed down, the distance between the lower edge of the arc-shaped area of ​​the handle 34 and the hinge point increases, thereby pressing the second positioning block 31 downward to improve the effectiveness and reliability of fixing the position of the positioning module 3. When the handle 34 is lifted, the distance between the lower edge of the arc-shaped area of ​​the handle 34 and the hinge point decreases, thereby releasing the second positioning block 31.

[0032] This utility model also includes a supporting base plate 4. The positioning base plate 1 is mounted on top of the supporting base plate 4 via a support member, and there is a gap between the bottom surface of the positioning base plate 1 and the top surface of the supporting base plate 4. The positioning base plate 1 is raised by the support member, and the supporting base plate 4 serves as the base of the entire positioning device, ensuring the stability of the overall structure of the positioning device, while facilitating the movement of the locking block 33 below the positioning base plate 1.

[0033] The support consists of several locking pins 5. Both the positioning base plate 1 and the support base plate 4 have several slots. One end of each locking pin 5 is inserted into a corresponding slot on the support base plate 4, and the other end is inserted into a corresponding slot on the positioning base plate 1. The shape of the locking pin 5 is as follows: Figure 6 As shown, corresponding limiting bosses are provided on both ends of the plate to ensure the effectiveness of supporting the positioning base plate 1 after insertion. Based on the design of this locking pin 5, the positioning base plate 1 and the support base plate 4 are easy and quick to install, and the positioning base plate 1 can be easily replaced according to different positioning requirements. To ensure the reliability of the insertion and engagement between the locking pin 5 and the slot, a 0.1mm gap is used between the locking pin 5 and the slot.

[0034] The positioning base plate 1 and the supporting base plate 4 have several slots that correspond to each other, and the number of slots is greater than the number of card slots. The first positioning block 2 is cylindrical and is inserted into the corresponding slots on the positioning base plate 1 and the supporting base plate 4, with the top of the first positioning block 2 protruding from the top surface of the positioning base plate 1. This design facilitates the installation of the first positioning block 2. Furthermore, since both the first positioning block 2 and the card slots are installed using card slots, it also allows for changing the installation position of the locking pin 5 and the first positioning block 2 according to actual positioning needs, enabling the first positioning block 2 to be inserted into slots at other positions on the positioning base plate 1 and the supporting base plate 4, thus providing more options for the installation position of the first positioning block 2.

[0035] An opening 13 is provided on the positioning base plate 1 at least one end of the first slide groove 11 and the second slide groove 12. The width of the opening 13 is greater than the width of the first slide groove 11, the second slide groove 12, and the positioning module 3, that is, greater than the width of the second positioning block 31 and the locking block 33. After the positioning module 3 is moved to the area where the opening 13 is located, the positioning module 3 can be completely released from the positioning base plate 1, so that the positioning module 3 can be moved in or out. This makes it easy to set the positioning module 3 on the positioning base plate 1, and also makes it easy to add or remove the number of positioning modules 3 on the positioning base plate 1 according to actual needs.

[0036] The first slide groove 11 and / or the second slide groove 12 have two or more, and the specific number can be processed according to the actual positioning needs of the production line while ensuring the integrity of the positioning base plate 1. For example Figure 1 , Figure 7 and Figure 8 As shown, there are two first slide grooves 11 and one second slide groove 12. The second slide groove 12 intersects with both first slide grooves 11. When there are more than two first slide grooves 11 and two slide grooves 12, in order to ensure the integrity of the positioning base plate 1, only one second slide groove 12 should intersect with all first slide grooves 11, and the remaining second slide grooves 12 should only intersect with one of the first slide grooves 11.
