[0042] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following description is given in conjunction with the embodiments and the accompanying drawings.

[0043] For curved trims, in order to make them fit on the contoured tooling, using clamps to clamp the product can easily leave dents on the product surface, causing refraction problems on the product. The suction force of the suction cup tool is easily limited by the size between the ribs of the product, and there is a certain risk of the product falling.

[0044] Based on this, please refer to Figures 1 to 4 The present application proposes a clamping mechanism, including a contouring tooling, an inner support assembly and a driving device; the inner support assembly is arranged on the contouring tooling, and a control end 1, a first movable end 2 and a second movable end 3 are provided on the inner support assembly. The driving device is transmission-connected to the control end 1, and the driving device can drive the first movable end 2 and the second movable end 3 to move closer to or away from each other; when the first movable end 2 and the second movable end 3 move away from each other, the first movable end 2 and the second movable end 3 jointly clamp the product located on the contouring tooling.

[0045] Preferably, the internal support assembly includes a first gear 4, a second gear 5, a mounting seat 6, a first internal support member 7 and a second internal support member 8; the first gear 4 and the second gear 5 are respectively rotatably arranged on the mounting seat 6; the first gear 4 is engaged with the second gear 5; the first internal support member 7 is arranged on the circumferential side wall of the first gear 4, and the second internal support member 8 is arranged on the circumferential side wall of the second gear 5; the mounting seat 6 is arranged on the contoured tooling 14; the driving device is transmission-connected to the first gear 4; the transmission connection of the first gear 4 is controlled by the driving device, and the first internal support member 7 and the second internal support member 8 can approach or move away from each other.

[0046] like Figure 2As shown, the first movable end 2 of the inner support assembly is composed of a first gear 4 and a first inner expansion member 7, and the second movable end 3 is composed of a second gear 5 and a second inner expansion member 8. The first gear 4 rotates synchronously with the first inner expansion member 7 when the first gear 4 rotates, and the second inner expansion member 8 rotates synchronously when the second gear 5 rotates, and the rocker 9 controls the rotation of the first gear 4 by swinging, and the control end 1 is located at the end of the rocker 9 away from the first gear 4; when in use, the driving device drives the first gear 4 to rotate; under the action of meshing transmission, the second gear 5 rotates accordingly; due to the meshing relationship, the rotation directions of the first gear 4 and the second gear 5 are opposite On the contrary; when the first gear 4 rotates clockwise, the second gear 5 rotates counterclockwise, and the first inner supporting part 7 and the second inner supporting part 8 approach each other; when the first gear 4 rotates counterclockwise, the second gear 5 rotates clockwise, and the first inner supporting part 7 and the second inner supporting part 8 move away from each other; after the product is fitted on the contoured tooling 14, the spacing between the first inner supporting part 7 and the second inner supporting part 8 can be reduced by rotating the first gear 4 clockwise, so that the first inner supporting part 7 and the second inner supporting part 8 can be extended into the position at the bottom of the product for internal support, such as a groove structure, and then the first gear 4 is rotated counterclockwise to complete the internal supporting fixation.

[0047] In some embodiments, a groove is provided on one side of the contoured tooling 14 for supporting the product, and the mounting base 6 is fixed in the groove; when the product is placed on the contoured tooling 14, the groove structure at the bottom of the product is against the first inner support member 7 and the second inner support member 8, thereby performing internal support fixation.

[0048] In some embodiments, as Figure 2 As shown, in order to improve stability, the first inner support member 7 and the second inner support member 8 can both adopt profiling members. For example, when the clamping object is a curved decorative strip 15, the bottom of which has a barb structure, the end of the first inner support member 7 and the end of the second inner support member 8 can be provided with the same barb, so as to hook together with the barb at the bottom of the curved decorative strip 15.

[0049] In some embodiments, as Figure 1 As shown, the driving device includes a swing rod 9 and a linear drive assembly; one end of the swing rod 9 is connected to the first gear 4, and the other end of the swing rod 9 corresponds to the movable end of the linear drive assembly; the linear drive assembly can control the swing rod 9 to swing, and the swing rod 9 drives the first gear 4 to rotate when it swings. Figure 2 As shown, the rotational control of the gear is converted into the swing control of the rocker 9, thus requiring only a linear drive assembly. Furthermore, because internally supported clamping is employed, the required range of movement of the first internally supported member 7 is limited to a certain angle. Therefore, using the swing angle of the rocker 9 for conversion control provides greater adaptability and simpler control.

[0050] In some embodiments, combined Figure 1 and Figure 3 As shown, the linear drive assembly includes a support base 10, a slider 11, a sliding control member 12, and a pusher 13. The support base 10 is provided with a slide rail, on which the slider 11 slides, and the pusher 13 is mounted on the slider 11. The end of the rocker arm 9 away from the first gear 4 corresponds to the pusher 13. When the slider 11 slides, the pusher 13 slides and swings the rocker arm 9. As the slider 11 moves, the pusher 13 pushes the rocker arm 9 away from the end of the first gear 4, thereby rotating the first gear 4. By controlling the movement distance of the slider 11, the rotation angle of the first gear 4 and the second gear 5 can be controlled accordingly, thereby controlling the internal expansion distance of the first and second internal expansion members 7 and 8.

[0051] And, as Figure 4 As shown, the pusher 13 is provided with a clearance opening 16, and the end of the swing rod 9 away from the first gear 4 is arranged through the clearance opening 16. Preferably, the clearance opening 16 is a U-shaped opening, and the two vertical sides of the U-shaped opening can limit the left and right positions of the swing rod 9, thereby pushing the swing rod 9 to the left or right respectively when the slider 11 slides horizontally to the left or right.

[0052] In some embodiments, as Figure 3 As shown, the sliding control member 12 includes an adapter 121, a mounting plate 125, a connecting rod 122, and an operating handle 123. The connecting rod 122 is axially slidably mounted on the support base 10, and its direction is parallel to the distribution direction of the slide rails. The connecting rod 122 is connected to the slider 11 via the adapter 121, and the operating handle 123 is mounted on the connecting rod 122. The mounting plate 125 is mounted on the support base 10 and has a through hole through which the connecting rod 122 is mounted. A sliding stop block 126 is provided on the side of the mounting plate 125 facing the operating handle 123.

[0053] During use, the operator manually controls the operating handle 123 to control the connecting rod 122 to slide, and the connecting rod 122 drives the slider 11 to slide synchronously through the adapter 121, swings the rocker arm 9, rotates the first gear 4, and completes the internal support.

[0054] like Figure 4As shown, the sliding control member further includes a transmission member 17, and the operating handle 123 includes an operating portion 1231 and a connecting portion 1232; one end of the transmission member 17 is hinged to the sliding limit block 126; the operating handle 123 drives the transmission member 17 to rotate, so that the connecting rod 122 slides; moreover, the operating portion 1231 is connected to one end of the connecting portion 1232, and the portion of the operating portion 1231 connected to the connecting portion 1232 is simultaneously hinged to the other end of the transmission member 17; the other end of the connecting portion 1232 is hinged to the connecting rod 122. Thus, the specific process for an operator to manually control the operating handle 123 to control the sliding of the connecting rod 122 is as follows:

[0055] First, in the initial state, as Figure 4 shown, the connecting portions among the operating portion 1231, the connecting portion 1232, and the transmission member 17 form a "T" - shaped structure; then, the operator rotates the operating portion 1231 in the direction indicated by the arrow of Figure 4 . Since the transmission member 17 is hinged to the sliding limit block 126 and the connecting portion 1232 is hinged to the connecting rod 122, the transmission portion and the connecting rod 122 rotate as the operating portion 1231 rotates; during the rotation process, the connecting portions among the operating portion 1231, the connecting portion 1232, and the transmission member 17 evolve into a "Y" - shaped structure, and under the hinged transmission effect, the rotation of the operating portion 1231 is converted into the sliding of the connecting rod 122.

[0056] When the sliding stroke of the connecting rod 122 is limited, the connection position of the adapter 121 on the connecting rod 122 is adjustable. By adjusting the installation position of the adapter 121, the moving range of the slider 11 relative to the swing rod 9 is correspondingly adjusted, thereby changing the magnitude of the swing angle change when the pushing member 13 of the slider 11 pushes the swing rod 9, and finally converting it into the modification of the magnitude range of the inner expansion distance between the first inner expansion member 7 and the second inner expansion member 8 for use in different products.

[0057] Specifically, as Figure 4 shown, the connecting rod 122 is a threaded rod, and two adjusting bolts 124 are provided on the connecting rod 122; one end of the adapter 121 is sleeved on the connecting rod 122 and clamped between the two adjusting bolts 124. Rotating the two adjusting bolts 124 changes the connection position of the adapter 121 on the connecting rod 122. In addition, as an alternative fixing solution, an adjusting bolt 124 can be rotatably provided on the adapter 121, and the adjusting bolt 124 is screwed into the connecting rod 122 during connection, or three or more adjusting bolts 124 can be provided to assist in fixing.

[0058] In some embodiments, the mounting base 6 is detachably mounted on the contoured tooling 14. Because the first inner expansion member 7 and the second inner expansion member 8 are contoured, the contoured tooling 14 and the mounting base 6 with different first inner expansion members 7 and second inner expansion members 8 can be replaced to accommodate different types of products, thereby increasing the flexibility of the mechanism.
