[0028] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0029] This utility model provides a novel double-sided table welding clamping mechanism (hereinafter referred to as "double-sided table welding clamping mechanism"), see [link to relevant documentation]. Figures 1-9 The double-sided welding clamping mechanism is installed on the automotive center channel assembly welding fixture 1 to fix the part fixture 8 on the automotive center channel assembly welding fixture 1. The part fixture 8 is used for welding the automotive center channel assembly. The automotive center channel assembly welding fixture 1 is provided with a connecting frame 3 for fixing the part welding fixture (i.e., part fixture 8, two sets of part fixtures are respectively distributed on the upper and lower surfaces of the connecting frame). The connecting frame 3 is provided with side suspensions 7 at both ends. The side suspensions are rotatably connected to the two end support platforms (one seat driven end and one seat active end). One of the support platforms is provided with a drive motor as the active end to meet the requirements of the part fixture flipping action.

[0030] See Figure 2 The double-sided welding clamping mechanism includes a locking mechanism 5 installed on the welding fixture 1 of the automotive center channel assembly, see [link / reference]. Figure 3 The locking mechanism 5 includes a safety seat 5a disposed on the side suspension surface, which has a transverse channel to meet the locking and unlocking needs of the safety latch. The top of the safety seat has a longitudinal channel leading to the transverse channel, which accommodates the assembly of the safety pin. The safety latch 5b, slidably mounted on the transverse channel of the safety seat, has multiple safety locking holes 5c along its length, for example, four equally spaced holes to meet the needs of four working positions. When the safety latch moves forward, it presses against the worktable of the part fixture; when it moves backward, it releases the worktable, facilitating the removal of the part fixture 8 from the automotive center channel assembly welding fixture 1. The safety pin 5d, installed in the longitudinal channel of the safety seat and engaging with the safety latch, prevents accidental sliding of the safety latch, thus preventing safety risks.

[0031] See also Figure 3The transverse channel outlet (i.e., the protrusion of the safety tongue block) of the safety seat 5a is provided with a U-shaped notch 5a-1 opened on the side wall of the transverse channel. There are two symmetrical U-shaped notches here (the structural surface of the safety tongue block can be observed through the notches during routine maintenance to see if it is damaged). The front end of the safety tongue block is provided with an outwardly protruding limiting protrusion 5b-1 as a limiting mechanism. During the retraction of the safety tongue block, the limiting protrusion can prevent the safety tongue block from falling out of the transverse channel. The limiting protrusion can be a transverse end block installed at the front end of the safety tongue block, which is embedded in the transverse groove provided at the front end of the safety tongue block.

[0032] See Figure 2 and Figure 4 The double-sided welding clamping mechanism also includes a bidirectional clamping device 2 distributed on both sides of the locking mechanism and installed at the side suspension. It includes a bidirectional clamping cylinder 6 and a four-bar clamping mechanism 4 installed on the bidirectional clamping cylinder. The bidirectional clamping action is completed by the bidirectional clamping cylinder at a single bidirectional clamping cylinder. Figure 2 The document describes two states of the four-bar clamping mechanism: the pressing part 4c is in the working position and the non-working position (the non-working position is when the pressing part is vertically distributed, and the working position is when the pressing part is horizontally distributed, at which time the clamping part tooling table is engaged). The four-bar clamping mechanism includes an irregularly shaped base 4a, a U-shaped side mounting block 4b, a pressing part 4c, and a duck-shaped block 4d. See details... Figures 5-8 As shown in the figures, the following descriptions are provided in conjunction with each figure:

[0033] See Figure 5 The irregularly shaped seat 4a is bolted to the side suspension surface. The seat 4a has a base 4a-1 (to provide a larger support surface to ensure the safety of the overall structure) and a vertical plate 4a-2 mounted on the base, thus accommodating the installation of corresponding supporting components in the height direction. The upper part of the vertical plate has symmetrically arranged square side ears 4a-3, and the two side ears have connecting openings to facilitate the installation of corresponding rotating shaft components. The irregularly shaped seat has a cantilever 4a-4 located at the edge of the base. This cantilever 4a-4 facilitates the installation of duck-shaped blocks 4d, which in turn connect to the clamping cylinder. It should be noted that a single duck-shaped block 4d only fixes one clamping cylinder. The bidirectional clamping cylinder, used to clamp parts in two directions, is fixed by two duck-shaped blocks 4d at their respective positions. For example… Figure 2 The two clamping cylinders shown are bidirectional clamping cylinders used to clamp the upper part tooling and the lower part tooling, respectively.

[0034] See Figure 6 The duck-shaped block 4d is mounted on the irregular seat wing via a pivot. The duck-shaped block 4d has a duck body 4d-1 for fixing the cylinder and a double duck head neck 4d-2 connected to the wing. The duck-shaped block 4d can meet the cylinder mounting requirements, which is crucial for the reasonable layout of space.

[0035] See Figure 7 The U-shaped side mounting block 4b is installed on the irregularly shaped base. The U-shaped side mounting block 4b has a vertically distributed side back 4b-1 and symmetrically distributed side wing blocks 4b-2 on the side back. The side back and the two side wing blocks form a U-shaped structure. The side back is provided with a rear protrusion 4b-3 for connecting the cylinder rod. The lower protrusions 4b-4 of the two side wing blocks are clamped and installed at the side ears of the upright plate by a rotating shaft.

[0036] See Figure 8 The pressing part 4c of the four-bar linkage clamping mechanism has a pressure rod 4c-1, a pressure head 4c-2 connected to the pressure rod, two L-shaped blocks 4c-3, and an H-shaped suspension block 4c-4. The two L-shaped blocks 4c-3 are symmetrically installed on the side of the tail of the pressure rod through a rotating shaft. The L-shaped blocks are located between the pressure rods. The upper part of the H-shaped suspension block is connected to the mounting hole at the top of the side wing block through a rotating shaft. The lower part of the H-shaped suspension block is connected to the pressure rod through a rotating shaft.

[0037] In this case, the surfaces of the press-fitting part and the safety tongue can be covered with carbon fiber cloth or glass fiber material. This ensures structural strength while also preventing scratches on the surfaces of the mating structures.

[0038] The working principle of this utility model is as follows:

[0039] 1. Place part fixture 8 (middle channel assembly) on the table of connecting frame 3.

[0040] 2. Four sets of 80 cylinders on one side (i.e., the cylinders required to fix the workpiece table on one of the surfaces of the connecting bracket when the workpiece is fixed) press the table, push the locking mechanism to the workpiece table, and insert the mounting pin.

[0041] 3. The clamping design is a four-bar linkage mechanism. Even if the tooling suddenly loses air pressure while in the clamping state, the tooling will not loosen.

[0042] 4. After placing one side, rotate the table of connecting bracket 3 180° and repeat the above actions to place another set of parts.

[0043] 5. The clamping cylinder makes reasonable use of space and there is no interference.

[0044] Those skilled in the art will understand that the above embodiments are specific examples of implementing the present invention, and in practical applications, various changes can be made to them in form and detail without departing from the spirit and scope of the present invention.
