[0024] The clamp of the present invention is mainly used for automatic clamping of beam parts of new energy vehicles. The clamp includes a base 10, a clamp body 20, a first clamping assembly, a support member 50, a second clamping assembly and a transfer mechanism 70. The clamp clamps the part to be clamped 40 in the horizontal direction through the first clamping member 30 and the clamp body 20, and clamps the part to be clamped 40 in the vertical direction through the second clamping member 60 and the support member 50, so as to achieve reliable fixation of the part to be clamped 40. In addition, the transfer mechanism 70 is movably arranged between the processing position and the avoidance position. During the loading and unloading process of the part to be clamped 40, the transfer mechanism 70 moves to the avoidance position to achieve the avoidance of the second clamping assembly to the part to be clamped 40. After the part to be clamped 40 is loaded, the transfer mechanism 70 moves to the processing position to enable the second clamping assembly to clamp the part to be clamped 40. It can be seen that the clamp solves the problem of interference between the clamp and the parts in the processing process of beam products in the prior art.

[0025] In specific implementation, the part 40 to be clamped is a beam-type component. The clamp helps to achieve the function of rapid clamping and positioning during the processing of the beam-type components, reduce product clamping time, improve processing efficiency, and focus on solving the difficulty of requiring the second clamping component to move as a whole to avoid interference.

[0026] In this embodiment, the transfer mechanism 70 includes a movable frame 71, and the first clamping assembly is arranged on the movable frame 71; the clamp also includes: a first driving member 80, which is arranged on the base 10, and the first driving member 80 is drivingly connected to the movable frame 71 to drive the movable frame 71 to move, so that the transfer mechanism 70 can switch between the processing position and the avoidance position.

[0027] Specifically, the first driving member 80 is a linear electric cylinder.

[0028] In this embodiment, the fixture further includes a slide rail and slider assembly, which includes a slide rail 91 and a slider 92 .

[0030] In this embodiment, the fixture also includes: a first stop block 100, which is arranged on the base 10, and the first stop block 100 is used to abut on the movable frame 71 to stop the transfer mechanism 70 at the processing position; and / or, a second stop block 110, which is arranged on the base 10, and the second stop block 110 is used to abut on the movable frame 71 to stop the transfer mechanism 70 at the avoidance position.

Such a setting realizes the fixing of the transfer mechanism 70, avoids displacement of the clamped member 40 during processing, and reduces the production accuracy.

[0032] Specifically, the third pressing member 121 is used to clamp the moving body 711 of the moving frame 71 .

[0033] Optionally, the clamp includes two third pressing assemblies, and the two third pressing assemblies are arranged on opposite sides of the moving body 711 .

[0034] During specific implementation, when the clamping member 40 is loaded and installed, the third clamping member 121 is relaxed, and the first driving member 80 pushes the transfer mechanism 70 away from the processing position. The position is determined by the second stop block 110 to ensure that there is no interference in the loading of parts. The movement of the transfer mechanism 70 is guided and supported by two sets of slide rail slider assemblies to ensure smooth and stable movement.

[0035] In this embodiment, the first clamping assembly also includes: a second driving member 31, which is arranged on the clamp body 20, and the telescopic rod of the second driving member 31 is connected to one end of the first clamping member 30; a first supporting portion, which is arranged on the second driving member 31, and the first clamping member 30 is rotatably connected to the first supporting portion.

[0036] Optionally, there are at least two first clamping assemblies to improve the clamping effect.

[0037] In this embodiment, the transfer mechanism 70 includes a mobile frame 71, the mobile frame 71 includes a mobile body 711 and a plurality of mounting posts 712, and the plurality of mounting posts 712 are arranged at intervals on the mobile body 711; the clamp includes a plurality of second clamping assemblies, the plurality of second clamping assemblies are arranged one-to-one correspondingly to the plurality of mounting posts 712, and each second clamping assembly is installed on the top of the corresponding mounting post 712. The arrangement of the plurality of second clamping assemblies improves the clamping effect.

[0038] In this embodiment, the second clamping assembly also includes: a third driving member 61, which is arranged on the transfer mechanism 70, and the telescopic rod of the third driving member 61 is connected to one end of the second clamping member 60; a second supporting part, which is arranged on the third driving member 61, and the second clamping member 60 is rotatably connected to the second supporting part.

[0039] Specifically, the second driving member 31 , the third driving member 61 and the fourth driving member 122 are all oil cylinders.

[0040] In this embodiment, the clamp also includes: a positioning member 130, which is arranged on the clamp body 20, and the positioning member 130 is used to abut against the positioning surface on the part to be clamped 40; and / or, a positioning pin 140, which is arranged on the clamp body 20, and the positioning pin 140 is used to be inserted into a positioning hole on the part to be clamped 40; and / or, a plurality of guide columns 150, which are arranged on the clamp body 20, and the plurality of guide columns 150 are arranged at intervals to guide and support the part to be clamped 40.

[0041] Optionally, there are at least two positioning members 130 and at least two positioning pins 140 .

[0042] In specific implementation, multiple guide columns 150 assist in loading, and positioning members 130 and positioning pins 140 are used to achieve surface positioning and hole positioning, thereby improving positioning reliability. After the part to be clamped 40 is positioned, the first clamping assembly moves to position and pre-clamp the part to be clamped 40. After positioning and pre-clamping, the first driving member 80 is controlled by the oil circuit to pull the transfer mechanism 70 close to the processing position, and the position is determined by the first stop block 100 to ensure that the second clamping assembly on the transfer mechanism 70 moves to the position to clamp the part to be clamped 40. After the transfer mechanism 70 moves to the processing position, the third clamping assembly clamps and fixes the transfer mechanism 70, and then controls multiple groups of second clamping assemblies in sequence through the oil circuit and oil circuit hose on the fixture body 20 to perform the clamping action of the part to be clamped 40, ensuring the effective fixation of the part to be clamped 40 to meet the needs of the part processing conditions. After automated processing, it becomes a finished part, and the oil circuit is controlled to release the first clamping assembly and the second clamping assembly, and the above-mentioned release process of the transfer mechanism 70 is performed in sequence to realize the action cycle.

[0045] The clamp of the present invention solves the problem of cylinder interference in loading and unloading of beam-type components by modularizing the cylinder that needs to be moved and designing an independent transfer mechanism to perform overall movement and control of the second clamping component.

[0046] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0047] The clamp of the present invention is mainly used for automatic clamping of beam parts of new energy vehicles.

In addition, the transfer mechanism 70 is movably arranged between the processing position and the avoidance position. During the loading and unloading process of the part to be clamped 40, the transfer mechanism 70 moves to the avoidance position to achieve the avoidance of the second clamping assembly to the part to be clamped 40.
