[0075] In this embodiment, the six-axis component 2 is connected to the back plate 3-1 via a connector.

This design facilitates the installation and subsequent use of the six-axis component and the clamping assembly.

[0076] Working principle of the robot: The six-axis robot (six-axis component) works to move the clamping assembly to a station (the first station) to clamp the part (the front floor assembly of the car). The first, second, third, fourth, fifth, and sixth flipping mechanisms are actuated to enable the first back clamping head to cooperate with the first front clamping head for clamping, the second back clamping head to cooperate with the second front clamping head for clamping, the third back clamping head to cooperate with the third front clamping head for clamping, the fourth back clamping head to cooperate with the fourth front clamping head for clamping, the fifth back clamping head to cooperate with the fifth front clamping head for clamping, and the sixth back clamping head to cooperate with the sixth front clamping head for clamping, so that the part (the front floor assembly of the car) is clamped by the clamping assembly (the first back clamping head). The six-axis robot cooperates with the slide (the slide is driven by the power device and moves in the lateral direction through the drive gear and rack) to move to another station (the second station). After it is in place, the six-axis robot places the part (the front floor assembly of the car) clamped by the clamping assembly on the second station. After it is in place, the first, second, third, fourth, fifth and sixth flipping mechanisms in the clamping assembly are reset, and the first front clamping head, the second front clamping head, the third front clamping head, the fourth front clamping head, the fifth front clamping head and the sixth front clamping head are flipped so that the clamping assembly does not clamp the workpiece, completing the placement of the part (the front floor assembly of the car). The six-axis robot then resets, slides to the first station via the slide, and repeats the grabbing and moving operations.

[0077] Example 3: The basic scheme is the same as Example 2, with the difference that an inner extension plate structure 1c (in the shape of a U) is provided on the inner circumference of the top of the base to protect the guide rails, etc., to prevent foreign objects from falling in and affecting normal use, and to improve the compactness of the base. An extension plate structure 1a is provided on one side of the top of the base (the extension plate structure and the rack are located on the same side of the base), and a U-shaped support frame 1b is provided at the bottom of the extension plate structure, and the U-shaped support frame is fixedly connected to the base. The above design facilitates the installation and use of auxiliary structures (including but not limited to drag chains), and at the same time forms an identification to a certain extent, that is, the position of the rack can be quickly determined by the position of the extension plate structure, which facilitates the installation and subsequent maintenance of the rack part.

[0078] The seat frame is unique in that it consists of four panels, each with a backing plate 1-1a at each end, a stopper 1-1b positioned above the backing plate, and multiple rectangular holes 1-2a circumferentially arranged around the upper portion of the panel. The special design of the seat panels elevates the mechanism and reduces weight, while the stoppers enhance the structural stability of the seat frame. Ventilation at the rectangular holes helps dissipate heat from the operating guide rail and reduces weight.

[0079] Example 4: The basic scheme is the same as Example 1 or Example 2 or Example 3, the difference is as follows Figure 25, multiple rack mounting holes 1-3a are provided on the rack, and bolts for fixing the rack are arranged at the rack mounting holes (after installation, the top height of the bolt is less than the height of the top of the rack mounting hole). Multiple protection plate mounting holes are provided on the L-shaped protective plate (the number of protection plate mounting holes and rack mounting holes is the same, and a protection plate mounting hole is arranged above each rack mounting hole), the protection plate mounting holes are provided with internal threads, and the upper ends of the protection plate mounting holes are provided with countersunk holes. The attachment rod component is arranged at the protection plate mounting hole, and the attachment rod component has an attachment rod 8-1 with external threads, a circular top head 8-1a is provided at the top of the attachment rod, and a circular bottom head 8-1b is provided at the bottom, and a polygonal operating port is provided in the center of the top of the circular top head (the polygonal operating port can be a hexagonal operating port, etc., which is convenient for tool twisting, and reference can be made to the existing technology), the attachment rod and the protection plate mounting hole are threadedly connected, and the top of the circular top head is flush with the top of the L-shaped protective plate (the circular top head is sunk into the countersunk hole), and the circular bottom head is pressed against the entrance of the rack mounting hole. The L-shaped protective plate has the risk of deformation due to pressure (collision), which affects the normal use of the mechanism. The above risk can be avoided (reduced) by the support of the auxiliary rod components arranged with appropriate density; at the same time, the auxiliary rod components seal the rack mounting holes to avoid (reduce) the exposure of the bolts to rust and affect disassembly and assembly, and facilitate subsequent maintenance and disassembly; the design of the top and bottom heads prevents the auxiliary rod from partially falling out of the mounting hole and falling into the gear meshing position to cause accidents. The flush setting of the circular top head allows visual inspection to check whether the auxiliary rod is installed in place in the later stage of installation.

[0080] Example 5: The difference between this example and Example 1 is that the rack mounting base is provided with notches 1-3-2 on one side to mount the rack. Since the notches are stepped, a rack positioning stop structure is provided at the end of the rack, which can improve both the stability and the accuracy of the rack mounting. Figures 26-27 The rack positioning and stopping structure includes a stop post 1-3-2a located at the end of the rack. The slot wall of the slot 1-3-2 is provided with a stop post hole that cooperates with the stop post. The cross-section of the stop post is T-shaped to prevent the stop post from falling out of the stop post hole. A wedge block movement channel 1-3-2b is provided on the lower slot wall of the slot, located below the stop post hole. A wedge block 1-3-2c is provided in the wedge block movement channel to cooperate with the stop post. One end of the wedge block is connected to a return spring 1-3-2d located in the wedge block movement channel and used to reset the wedge block, allowing the stop post to descend and enter the stop post hole. A push screw 1-3-2e is provided at the end of the lower slot wall of the slot, which can be screwed into the wedge block movement channel. Figure 27This is the effect diagram of the stop column in the stop positioning state after it is raised. At this time, the right end of the push screw enters the wedge moving block after passing through the screw hole, pushing the wedge to the right until the surface of the wedge pushes the stop column out of the stop column hole. Conversely, after the stop screw exits the wedge movement channel, under the action of the reset spring, the wedge moves to the left, and the stop column drops until the upper surface is flush with the working surface of the slot.

[0081] The appearance of the reset spring can keep the stop column in the rack mounting seat bar of repeated vibration in the pop-up state without automatically falling. When the stop column needs to be lowered, push the screw out of the screw hole and the spring will Figure 27 In the state shown, push the wedge with the inclined surface to the left, so that the stop post slowly descends into the stop post hole to be in this state.

[0082] As a further improvement to this embodiment, see Figures 28-29 The wedge motion channel is equipped with a release mechanism 1-3-2f. This is because the wedge motion channel is relatively closed, and the lubricating oil inside needs to be released and injected. Through this release mechanism, the deteriorated lubricating oil can be released outwards, and the release mechanism can also be used to reversely inject lubricating oil to improve the smooth movement and service life of the internal mechanism. When installing the release mechanism, the end of the rack mounting seat bar 1-3-1 needs to be partially cantilevered so that the operating part of the mechanism is exposed to facilitate the operator's operation. For example, if the lower surface of the rack mounting seat bar is also provided with a corresponding fixing seat or other supporting structure, the end of the rack mounting seat bar needs to be cantilevered about 3-5cm to facilitate the exposure of the operating part of the release mechanism. The lower surface of the wedge block movement channel is provided with a circular stepped recess and a cylindrical channel communicating with the circular stepped recess and extending to the lower surface of the rack mounting seat strip. The circular stepped recess is provided with a circular head 1-3-2f-1. When the circular head is placed in the circular stepped recess, the release through hole cannot be communicated with the inner cavity of the wedge block movement channel. On the contrary, the inner cavity of the wedge block movement channel is kept in communication with the through hole. Figure 29The release mechanism is in the closed state. The cylindrical channel is equipped with a cylindrical body 1-3-2f-2 connected to the circular head. The cylindrical body is an operating structure. The circular head enters the inner cavity of the wedge motion channel by pushing up, and then the horizontal through hole 1-3-2f-3 provided in the radial direction of the circular head is connected to the inner cavity of the wedge motion channel. The cylindrical body is provided with a vertical through hole 1-3-2f-4 connected to the horizontal through hole. This vertical through hole can release the deteriorated lubricating fluid inside the wedge motion channel to the outside. The side wall of the cylindrical channel is provided with a ring shaped inner groove, the annular inner groove is provided with a straight-line side ear 1-3-2f-5 which is an integral structure with the cylindrical body, and the annular inner groove is provided with a closing spring 1-3-2f-6 which is connected to the straight-line side ear and keeps the release mechanism in a closed state. This closing spring can keep the release structure in a normally closed state, and when an external force pushes the cylindrical body upward, the release mechanism can be placed in an open state, thereby completing the external discharge of deteriorated lubricating oil or the reverse injection of lubricating oil inward. Note that the reverse injection of lubricating oil can only be carried out after the external discharge work is completed.
