Description

Technical Field

[0001] This utility model relates to clamping technology, specifically an arc-shaped plate auxiliary clamp. Background Technology

[0002] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for construction or inspection. It is also called a clamp. When processing and inspecting curved plates, a support structure is set at the bottom of the curved plate, and fixtures are needed on both sides of the curved plate to prevent the curvature of the side of the curved plate from changing due to gravity, thus ensuring the accuracy of the processing and inspection of the curved plate.

[0003] However, existing clamps are generally fixed on the support, making it impossible to adjust their position according to the size of the curved plate, and it is also difficult to adjust the clamping angle according to the side angle of the curved plate. Utility Model Content

[0004] To address the shortcomings of the prior art, this utility model provides an auxiliary clamp for curved plates, which can quickly and effectively adjust the position and clamping angle of the clamp according to the size of the curved plate and the angle of its side.

[0005] To achieve the above technical objectives, the present invention adopts the following technical solution: an auxiliary clamp for an arc-shaped plate, comprising two telescopic units, one end of which is provided with a ball joint, and the other end of which is provided with a hinge joint or a clamping unit, wherein the clamping unit is used to clamp the side of the arc-shaped plate;

[0006] The clamping unit includes a locking block, a clamping block, and a quick clamp. The locking block has a slot, which is arc-shaped. The locking block has a limiting component. The clamping block has a protrusion below it. The clamping block and the protrusion cooperate to form a cylinder. A clamping groove is provided between the clamping block and the protrusion. The clamping block is rotatably connected to the slot through the limiting component. Both ends of the protrusion have fixing posts, and both fixing posts are fixed to a fixing plate. The quick clamp is set on the fixing plate. The quick clamp drives the clamping end to extend and retract. The clamping end passes through the fixing plate to cooperate with the clamping block to clamp the side of the arc-shaped plate.

[0007] Preferably, the telescopic unit includes a first telescopic rod, a second telescopic rod, and a third telescopic rod. The ball joint is fixed to one end of the first telescopic rod, the other end of the first telescopic rod is sleeved on one end of the second telescopic rod, and the other end of the second telescopic rod is sleeved on the third telescopic rod.

[0008] Preferably, the hinge joint and the locking block are respectively fixed to the ends of the two third telescopic rods, and the hinge joint is used to realize the hinged connection of the two third telescopic rods.

[0009] Preferably, both the first telescopic rod and the second telescopic rod are equipped with clamps.

[0010] Preferably, both the locking block and the clamping block are provided with a clearance groove, which is used to guide the clamping end through the locking block and the clamping block.

[0011] Preferably, the limiting component includes a pin and a slot, the pin passing through the top of the clamping block and extending into the slot, and the slot being disposed on the outer wall of the clamping block and slidingly engaging with the pin.

[0012] In summary, this utility model achieves the following technical effects:

[0013] The auxiliary clamp for the arc plate of this utility model adopts two telescopic units, which can adjust the position of the clamping unit according to the size of the arc plate. The two telescopic units are hinged to each other, which increases the load-bearing capacity and can effectively prevent the clamping unit from being misaligned during clamping. In addition, through the cooperation of the rotatable clamping block and quick clamp, the clamping angle can be quickly adjusted according to the angle of the side of the arc plate.

[0023] Example 1:

[0024] like Figure 1As shown, an auxiliary clamp for an arc-shaped plate includes two telescopic units. One end of each telescopic unit is provided with a ball joint 1, and the other end of each telescopic unit is provided with a hinge joint 6 or a clamping unit. The clamping unit is used to clamp the side of the arc-shaped plate. Each telescopic unit includes a first telescopic rod 2, a second telescopic rod 3, and a third telescopic rod 4. The ball joint 1 is fixed to one end of the first telescopic rod 2, the other end of the first telescopic rod 2 is sleeved on one end of the second telescopic rod 3, and the other end of the second telescopic rod 3 is sleeved on the third telescopic rod 4. The hinge joint 6 and the locking block 7 are respectively fixed to the ends of the two third telescopic rods 4. The hinge joint 6 is used to realize the hinged connection of the two third telescopic rods 4.

[0025] The ball joint 1 allows the telescopic unit to be fixed to the bracket.

[0026] The arc plate auxiliary clamp of this embodiment uses two telescopic units, which can adjust the position of the clamping unit according to the size of the arc plate. The two telescopic units are hinged to each other, which increases the load-bearing capacity and can effectively prevent the clamping unit from being misaligned during clamping.

[0027] The first telescopic rod 2 and the second telescopic rod 3 are both equipped with clamps 5; the clamps 5 are used to fix the first telescopic rod 2 and the second telescopic rod 3, the second telescopic rod 3 and the third telescopic rod 4, thereby fixing the position of the clamping unit.

[0028] like Figure 2 As shown, the clamping unit includes a locking block 7, a clamping block 9, and a quick clamp 14. The locking block 7 has a slot, which is arc-shaped, so the locking block 7 is U-shaped. The locking block 7 has a limiting component. The clamping block 9 has a protrusion below it, making the clamping block 9 cylindrical. A clamping groove is provided between the clamping block 9 and the protrusion to allow the side of the arc-shaped plate to enter. The clamping block 9 is rotatably connected to the slot through the limiting component. Both ends of the clamping block 9 have fixing posts 11, and both fixing posts 11 are fixed to a fixing plate 12. The quick clamp 14 is disposed on the fixing plate 12. The quick clamp 14 drives the clamping end 13 to extend and retract. The clamping end 13 passes through the fixing plate 12 to cooperate with the clamping block 9 to clamp the side of the arc-shaped plate. The limiting component includes a pin 8 and a pin groove 10. The pin 8 passes through the top of the locking block 7 and extends into the slot. The pin groove 10 is disposed on the outer wall of the clamping block 9 and slides with the pin 8.

[0029] When the clamping end 13 and the clamping block 9 are used to clamp the side of the arc plate, the clamping clamp 14 can quickly move backward. Through the fixing plate 12 and the fixing post 11, the protrusion moves away from the clamping block 9, so that the protrusion and the clamping block 9 are stuck in the inner wall of the slot, limiting the radial rotation of the clamping block 9 and the clamping block 7, and ensuring the clamping effect.

[0030] Both the bottom of the clamping block 7 and the middle of the protrusion are provided with a clearance groove. The clearance groove is used to guide the clamping end 13 through the clamping block 7 and the clamping block 9. At the same time, the clearance groove can limit the movement of the clamping end 13 in the axial direction of the clamping block 7, prevent the clamping block 7 from moving axially, and ensure the clamping effect.

[0031] The arc plate auxiliary clamp of this embodiment, through the cooperation of the rotatable clamping block 9 and the quick clamp 14, can quickly adjust the clamping angle by rotating the clamping block 9 inside the clamping block 7 according to the angle of the side of the arc plate.

[0032] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall fall within the scope of the technical solution of the present utility model.
