Referring to fig. 1 and 2, an embodiment of the invention provides a clamping workbench 100, and the clamping workbench 100 is used for clamping an automobile body-in-white 200 so as to assemble the automobile body-in-white 200 in a subsequent step. For example, in some embodiments, when the assembling device including the clamping workbench 100 is used for assembling the automobile body-in-white 200, the clamping workbench 100 can be used for stabilizing the part of the automobile body-in-white 200, which needs to be welded. It should be noted that, the assembling device is used as a main structure of the welding production line, the assembling device includes a welding gun, and the welding gun is used for welding the automobile body-in-white 200 placed on the clamping workbench 100, so that the smaller the occupied space of the clamping workbench 100 is, more space is left to meet the moving requirement of the welding gun on the automobile body-in-white 200 in the welding process, thereby effectively reducing the welding blind spots and improving the welding quality of the automobile body-in-white 200.

Specifically, the clamping table 100 includes a frame 10, a first clamp mechanism 20, and a plurality of second clamp mechanisms 30. Wherein the frame 10 has a top and a side, the first clamping mechanism 20 is mounted to the side of the frame 10, and the second clamping mechanism 30 is mounted to the top of the frame 10. It should be noted that the top and side portions of the frame 10 are those of the automobile body-in-white 200, and specifically, when the clamping table 100 clamps the automobile body-in-white 200, the side portions of the frame 10 correspond to the side portions of the automobile body-in-white 200, and the top portion of the frame 10 corresponds to the side portions of the automobile body-in-white 200. In this embodiment, the first fixture mechanism 20 is mounted on the side portion of the frame 10, so that the first fixture mechanism 20 can conveniently clamp and fix the side portion of the automobile body-in-white 200, and the subsequent assembling stability of the automobile body-in-white 200 is facilitated.

Because the first sliding table 21 can move relative to the frame 10 along the first direction, and the second sliding table 22 can move relative to the first sliding table 21 along the second direction, the mounting seat 23 arranged on the second sliding table 22 can drive the corresponding position of the side portion of the automobile body-in-white 200 of the first tooling fixture to be adjusted, so that the first tooling fixture can clamp the position, which needs to be fixed, on the side portion of the automobile body-in-white 200. Understandably, a plurality of second sliding tables 22 can meet the installation and moving requirements of a plurality of first tool fixtures, so that the side portions of the automobile body-in-white 200 can be clamped and fixed at multiple points by the aid of the first tool fixtures, and in this way, the positions, required to be welded, of the side portions of the automobile body-in-white 200 can be clamped and fixed at different positions by adjusting the first tool fixtures, so that the clamping requirements of the automobile body-in-white 200 of different automobile types can be met, the positions, required to be welded, can be reserved in the mode, more spaces can be emptied to facilitate welding of the automobile body-in-white 200 by a welding gun, the accessibility of welding spots can be guaranteed, the welding blind spots can be reduced, and the welding quality of the automobile body-in-white 200 is improved.

The first sliding table 21 and the second sliding table 22 are slidably connected through a sliding assembly 24, specifically, the sliding assembly 24 includes a guide rail 24a and a slider 24b slidably engaged with the guide rail 24a, where the guide rail 24a is disposed on the first sliding table 21, and the slider 24b is connected with the second sliding table 22.

Referring to fig. 5 and 6, a plurality of second fixture mechanisms 30 are disposed at intervals at the top along the second direction, each second fixture mechanism 30 includes a third sliding table 31, a fourth sliding table 32 and a mounting plate 33, the third sliding table 31 is movable relative to the frame 10 along the second direction, the fourth sliding table 32 is movable relative to the third sliding table 31 along the third direction (e.g., the O-Z direction shown in fig. 1), the mounting plate 33 is connected to the fourth sliding table 32 and is movable relative to the fourth sliding table 32 along the first direction, the mounting plate 33 is used for mounting a second fixture, and the second fixture is used for corresponding to the top of the white body 200 of the automobile. Under the structure setting, the second tooling fixture on the mounting plate 33 can be adjusted to different positions along the first direction, the second direction and the third direction relative to the frame 10, so that the requirement that the top of the white automobile body needs to be fixed to be clamped by the second tooling fixture is met, and in the second fixture mechanisms 30, a plurality of second tooling fixtures can form a plurality of freely-moving clamping fixed points to adapt to multi-point clamping of the top of the white automobile body 200 of the automobile, and the clamping fixing requirement of the top of the white automobile body 200 of the automobile of different types can be met by adjusting the positions of the plurality of tooling fixtures relative to the frame 10.

It should be noted that, in the embodiment of the present invention, the first direction, the second direction and the third direction are perpendicular to each other, and correspond to the X axis, the Y axis and the Z axis in the three-dimensional rectangular coordinate system.

The third slide table 31 and the fourth slide table 32 may be slidably connected, and the mounting plate 33 and the fourth slide table 32 may be slidably connected. The sliding connection structure may be a sliding rail and a sliding block which are slidably engaged with each other, and will not be described herein.

As shown in fig. 1, 6 and 7, in some embodiments, the frame 10 includes a supporting frame 11 and a cross beam 12, the cross beam 12 is connected to the top of the supporting frame 11, and the third sliding tables 31 of the second clamping mechanisms 30 are slidably connected to the cross beam 12, so that the second clamping mechanisms 30 can freely move relative to the cross beam 12 along the second direction to clamp a portion of the top of the body-in-white 200 of the automobile, which needs to be fixed. Through the structure setting, to the automobile body-in-white 200 of different motorcycle types, a plurality of second fixture mechanism 30 have good adaptability, then when needs are fixed to the automobile body-in-white 200 of different motorcycle types, a plurality of second fixture mechanism 30 only need adapt to the position of the relative frame 10 of adjustment, and need not to carry out the switching of large batch anchor clamps, just so reduce anchor clamps and store and switch required occupation of land space, in order to do benefit to taking welder to add man-hour to the automobile body-in-white 200, increase welder's activity space, reduce the welding blind spot, the welding quality of automobile body-in-white 200 has been improved.

It should be noted that there are many possibilities for the sliding connection structure of the third slide table 31 with the cross beam 12 as long as the third slide table 31 can slide in the second direction with respect to the cross beam 12. For example, as shown in fig. 1 and 6, a sliding block 31a is connected to the third sliding table 31, the cross beam 12 is provided with a sliding rail 12a, and the sliding block 31a is matched with the sliding rail 12a to enable the third sliding table 31 to be slidably connected with the cross beam 12. The slide rail 12a extends along the second direction, so that when the third slide table 31 slides along the slide rail 12a, the second clamp mechanism 30 corresponding to the third slide table 31 integrally slides along the slide rail 12 a. In other embodiments, the third sliding table 31 may also be in sliding fit with the cross beam 12 in a manner of a sliding protrusion and a sliding groove. Specifically, one of the third sliding table 31 and the cross beam 12 is provided with a sliding projection, and the other is provided with a sliding groove matched with the sliding projection, so that the sliding connection between the third sliding table 31 and the cross beam 12 is realized by the sliding fit of the sliding projection and the sliding groove.

The structure of the frame 10 is not limited to the above type, and rather, the supporting frame 11 may be replaced by other structures capable of supporting, such as a base, etc., and correspondingly, the cross beam 12 may be replaced by a plate-shaped structure or a bar-shaped material. The structure of the frame 10 is not limited herein, as long as it can meet the installation requirements of the respective mechanisms in the clamping table 100 and does not interfere with the movement of the respective mechanisms.

For convenience, the mounting of the first clamp mechanism 20 will be further described with respect to the frame 10 structure shown in fig. 7.

Specifically, the frame 10 includes a bottom plate 13 and a connecting seat 14, the bottom plate 13 is disposed between the support frames 11, the connecting seat 14 is connected with the bottom plate 13, and the connecting seat 14 is configured to be slidably connected with the first sliding table 21, so that the first clamp mechanism 20 as a whole can move relative to the frame 10. The sliding connection between the connecting seat 14 and the first sliding table 21 can refer to the sliding connection between the third sliding table 31 and the cross beam 12, which is not described herein in detail. For example, as shown in fig. 7 and 8 in conjunction, the first slide table 21 is slidably connected to the connection base 14 via a plurality of linear guide rails 21a arranged in parallel, thereby achieving the sliding connection of the first slide table 21 to the frame 10.

Further, the frame 10 includes a plurality of coupling seats 14, and the plurality of coupling seats 14 are coupled to opposite sides of the bottom plate 13, so that the first clamping mechanism 20 can be conveniently provided to both sides of the frame 10. For example, as shown in connection with fig. 7 and 8, 2 sides of the frame 10 are each provided with a first clamp mechanism 20. In this way, the first clamping means 20 on different sides can be adjusted to the clamping fixing requirements of the respective side of the body-in-white 200 of the motor vehicle.

The clamping table 100 includes a first driving mechanism (not shown) for driving the 2 sets of first clamping mechanisms 20 to approach or move away from each other along a first direction, so as to efficiently adapt to the widths of different automobile body-in-white 200. It is understood that when only one set of first fixture mechanisms 20 is provided on the clamping table 100, the first fixture mechanisms 20 may be moved in the first direction by providing a first driving mechanism on the clamping table 100.

The first drive mechanism may be a motor-screw arrangement, for example, a motor that drives the screw in a rotational motion such that the screw threadingly drives the first clamp mechanism 20 in a first direction. The first drive mechanism may also be a motor-driven wheel arrangement, for example, a motor that supports the first gripper mechanism 20 in a first direction by driving the wheel in rotation. In other embodiments, the first driving mechanism may also be a motor-driven gear structure, for example, a motor is used to drive the driving gear to rotate, and the driving gear is engaged with a rack gear disposed on the frame 10, so that when the motor drives the driving gear to rotate, the first clamping mechanism 20 is moved in the first direction by the engaging transmission force of the driving gear and the rack gear. The structure of the first driving mechanism is not described herein, as long as the first clamping mechanism 20 can be driven to move along the first direction relative to the frame 10.

In some embodiments, the first sliding table 21 is provided with a plurality of second driving mechanisms (not shown), and the plurality of second driving mechanisms are respectively used for driving the plurality of second sliding tables 22 to move along the second direction relative to the first sliding table 21, so that the requirement that each second sliding table 22 moves in the second direction relative to the frame 10 efficiently is met, and the clamping and fixing requirements of different automobile body-in-white 200 can be met quickly.

In some embodiments, the first fixture mechanism 20 includes a third driving mechanism (not shown) for driving at least a portion of the mounting seat 23 to move in a third direction relative to the corresponding second sliding table 22, so as to adapt to the height adjustment requirement of the mounting seat 23, so that the first fixture can clamp and fix the portions of the side portion of the vehicle body-in-white 200 at different height positions.

It should be noted that, the structures of the second driving mechanism and the third driving mechanism may refer to the first driving mechanism, for example, a motor-screw structure, a motor-driving wheel structure, or a motor-driving gear structure, which are not described herein again.

Referring to fig. 1 again, in some embodiments, the clamping workbench 100 includes a plurality of third clamping mechanisms 40, the plurality of third clamping mechanisms 40 are all located below the second clamping mechanism 30, and the third clamping mechanisms 40 are used for corresponding to the bottom of the automobile body-in-white 200, so as to meet the requirement of clamping the part of the bottom of the automobile body-in-white 200, which needs to be fixed.

In embodiments where frame 10 includes a base plate 13 and attachment sockets 14, a plurality of third clamp mechanisms 40 may be mounted on base plate 13. Further, a plurality of third fixture mechanisms 40 are arranged on the bottom plate 13 in an array manner, so that the whole structure of the clamping workbench 100 is compact, and the space above the bottom plate 13 is fully utilized to meet the requirement of clamping the bottom of the automobile body-in-white 200.

Referring to fig. 9, the third fixture mechanism 40 includes a first translating assembly 41, a second translating assembly 42 and a lifting assembly 43, the first translating assembly 41 and the second translating assembly 42 are respectively used for driving the lifting assembly 43 to move along a first direction and a second direction, the lifting assembly 43 is used for driving the third fixture to move along a third direction, and the third fixture is used for clamping the bottom of the body-in-white 200 of the automobile. The third fixture mechanism 40 can move in the first direction, the second direction and the third direction at the bottom of the automobile body-in-white 200, so that the fixture can clamp different positions of the bottom of the automobile body-in-white 200 and can meet the clamping and fixing requirements of body-in-white of different automobile types.

The first translating assembly 41, the second translating assembly 42 and the lifting assembly 43 may be identical in structure to simplify the structure of the third clamping mechanism 40 and reduce costs. Taking the structure of the first translating assembly 41 as an example, the first translating assembly 41 may include a horizontal sliding rail 12a, a horizontal sliding block 31a, and a driving mechanism for driving the horizontal sliding block 31a to move along the horizontal sliding rail 12a, where the driving mechanism may be, for example, a motor-screw structure, a motor-driving wheel structure, or a motor-driving gear structure, and the structure of the driving mechanism is not described herein again.

In some embodiments, the plurality of third clamping mechanisms 40 are arranged in the array on the bottom plate 13 and located between the 2 sets of first clamping mechanisms 20 arranged oppositely, so that the structure of the assembling device is compact and occupies a small space. Moreover, the 2 groups of first fixture mechanisms 20 can respectively clamp and position the left side and the right side of the automobile body-in-white 200, so that the clamping and positioning efficiency is improved.

Each of the 2 sets of first clamp mechanisms 20 is capable of independently moving toward the bottom plate 13 or away from the bottom plate 13 in the first direction, so that clamping positioning of both sides of the automotive body-in-white 200 can be independently performed. Specifically, when only one side of the body-in-white 200 of the automobile needs to be welded, the first fixture mechanism 20 on the corresponding side operates, and the first fixture mechanism 20 on the other side can be in a stop or standby state, so that the overall energy consumption of the clamping workbench 100 is reduced. It should be noted that after the welding of the body-in-white 200 is completed, another set of the first clamping mechanisms 20 may be used to clamp and position the other side. It will be appreciated that the 2 groups of first fixture mechanisms 20 are each independently capable of moving in a first direction toward the base plate 13 or away from the base plate 13, such that the operating states of the 2 groups of first fixture mechanisms 20 do not interfere, i.e., can be moved simultaneously, or can be operated in steps as previously described.

In other embodiments, the 2 sets of first clamping mechanisms 20 are linked through a transmission mechanism, and when one set of first clamping mechanisms 20 approaches the bottom plate 13 along the first direction, the transmission mechanism drives the other set of first clamping mechanisms 20 to approach the bottom plate 13 along the first direction. Through the structure arrangement, the movement of the 2 groups of first clamp mechanisms 20 has synchronicity, and for the symmetrical structure of the automobile body-in-white 200, the 2 groups of first clamp mechanisms 20 can realize centered clamping and alignment of the automobile body-in-white 200, so that the clamping and positioning efficiency is improved, and meanwhile, the 2 groups of first clamp mechanisms 20 are linked through the transmission mechanism, so that only one group of driving mechanisms need to be configured, and the driving mechanisms do not need to be respectively configured to realize the opposite movement or the back-to-back movement between the 2 groups of first clamp mechanisms 20. Wherein, the movement in opposite directions means that the 2 groups of first clamp mechanisms 20 are close to each other, and the movement in opposite directions means that the 2 groups of first clamp mechanisms 20 are far away from each other.

The construction of the transmission mechanism has a plurality of embodiments, which are described below by way of example only.

In some embodiments, the transmission mechanism includes a first rack, a second rack, and a transmission gear, the first sliding table 21 of the 2 sets of first clamping mechanisms 20 is respectively connected with the first rack and the second rack, the first rack and the second rack are engaged with different sides of the transmission gear, and the transmission gear is rotatably disposed on the frame 10 and is used for engaging and transmitting the first rack and the second rack to move in opposite directions. Through the structure, when the transmission gear is meshed with the first rack and the second rack to move towards the opposite direction, the first sliding table 21 of the 2 groups of first fixture mechanisms 20 respectively connected with the first rack and the second rack moves towards the opposite direction, and then the 2 groups of first fixture mechanisms 20 move towards or back to back on the two opposite sides of the bottom plate 13, so that the requirements of clamping and positioning parts on the left side and the right side of the automobile body-in-white 200 are met.
