Description

Technical Field

[0001] The utility model relates to the technical field of clamps, in particular to a clamp for processing carbon fiber composite materials. Background Art

[0002] Carbon fiber composite parts are generally formed as a whole after laying and curing. In order to meet the requirements of assembly and dimensional accuracy, they need to be further processed by milling and other secondary processing. They need to be reliably clamped before processing to prevent vibration and deformation. At present, there is a modular vacuum adsorption combination fixture specially used for wall panel milling. The fixture can quickly position and clamp the workpiece by adsorbing it through a suction cup. However, the modular adsorption fixture cannot be adjusted in height and the inclination angle of the panel, and cannot achieve the follow-shaped adsorption of the carbon fiber composite workpiece.

[0003] In order to solve the above technical problems, a Chinese patent application with publication number CN107414552A discloses an adjustable adsorption fixture for milling carbon fiber composite materials, which realizes accurate adjustment of the height of the carbon fiber composite material workpiece by setting a lead screw nut, a sliding guide rail and a fastening bolt; by adjusting the angle of the support seat and the support rib, the inclination angle of the carbon fiber composite milling workpiece is adjusted, and the shape-adsorption of the slightly curved workpiece is realized. However, this solution still has defects: the support rib and the support seat are connected by an ordinary hinge method. When the workpiece is placed on the suction cup to calibrate the relative angle between the support rib and the support seat, the workpiece will exert pressure on the support seat due to its own gravity, thereby forcing the support seat to rotate relative to the support rib. In order to prevent the support seat from slipping, it is necessary to press the support seat manually, and then use the fastening bolts to fix the support seat and the support rib. Therefore, the operation of the device is cumbersome and inefficient. Utility Model Content

DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0046] See also Figure 1-5 The utility model provides a technical solution: a fixture for processing carbon fiber composite materials, comprising: a support platform 3 and at least one adsorption component for positioning a workpiece arranged on the support platform 3. In this embodiment, the adsorption component has three components and is arranged in a central ring about the support platform 3. The adsorption component includes a suction cup 24 and a movable rod 21 connected to the suction cup 24 at one end; a bracket 17 with a movable groove, and the other end of the movable rod 21 is rotatably arranged in the movable groove; at least one clamping plate 18 that fits the side of the movable rod 21. In this embodiment, the clamping plate 18 has two components and is symmetrically arranged front and back about the bracket 17; an elastic structure for keeping the clamping plate 18 and the movable rod 21 in a fitting state; a driving component for driving the clamping plate 18 to apply a tightening force to the movable rod 21;

[0047] The above-mentioned technical solution can realize the pre-fixation of the movable rod 21. When in use, the workpiece is placed on the suction cup 24, and the movable rod 21 is rotated to make it rotate in the movable groove of the bracket 17. Since the clamp 18 is provided, the clamp 18 can keep in contact with the movable rod 21 under the action of the elastic structure, thereby forming a large damping effect on the movable rod 21 to prevent the workpiece from pressing the movable rod 21. Therefore, there is no need to manually press the movable rod 21 to prevent it from moving, and the operation is relatively convenient. After manually adjusting the angle of the movable rod 21 to an appropriate level, the clamp 18 applies a tightening force to the movable rod 21 by controlling the drive assembly, thereby fixing the movable rod 21 and completing the angle adjustment; preferably, the suction cup 24 can be externally connected to a vacuum pump (not shown in the figure) to increase the adsorption force of the suction cup 24 on the surface of the workpiece.

[0048] like Figure 4 As shown, in this embodiment, a rotating groove 19 and an arc groove 20 are formed on the surface of the clamping plate 18, the center of the rotating groove 19 coincides with the center of the arc groove 20, a rotating column 22 rotatably matched with the rotating groove 19 is provided on the side of the movable rod 21, and a sliding column 23 slidably matched with the arc groove 20 is provided on the side of the movable rod 21;

[0049] The above technical solution can ensure that the movable rod 21 can stably rotate in the movable groove of the bracket 17. When rotating, the rotating column 22 of the movable rod 21 rotates around the rotating groove 19, and at the same time, the sliding column 23 slides along the arc groove 20, thereby realizing the angle adjustment of the movable rod 21.

[0050] like Figure 3 As shown, in this embodiment, the elastic structure includes: an elastic member 27 having one end fixed to the movable groove, and the other end of the elastic member 27 is connected to the clamping plate 18; a limiting rod 25 is provided on the side of the clamping plate 18 away from the movable rod 21, and the limiting rod 25 is slidably matched with the limiting groove 26 provided on the surface of the bracket 17;

[0051] The above-mentioned technical solution can make the splint 18 apply damping pressure to the movable rod 21 to prevent the movable rod 21 from being easily moved. When in use, due to the provision of the elastic member 27, the elastic member 27 can apply elastic force to the splint 18, so that the splint 18 fits with the movable rod 21, so that the movable rod 21 will not loosen easily. The limiting rod 25 and the limiting groove 26 can guide the movement direction of the splint 18 to prevent the splint 18 from rotating or shaking, thereby improving the stability of the structure; preferably, the splint 18 is provided with an anti-slip structure in the area where it fits with the movable rod 21, such as anti-slip protrusions or anti-slip grooves (not shown in the figure), so as to increase the fastening force of the splint 18 on the movable rod 21.

[0052] like Figure 2 and Figure 3As shown, in this embodiment, the driving assembly includes: a second threaded rod 28, which cooperates with a threaded groove 29 provided on the surface of the bracket 17; a first locking nut for locking the second threaded rod 28; a pressure block 30, which is rotatably disposed at one end of the second threaded rod 28 close to the clamping plate 18; a first turning handle 31, which is disposed at one end of the second threaded rod 28 away from the pressure block 30;

[0053] The above-mentioned technical solution can enable the clamping plate 18 to clamp the movable rod 21. When in use, the first turning handle 31 is rotated to drive the second threaded rod 28 to rotate, and the second threaded rod 28 drives the pressure block 30 to approach the clamping plate 18 until the pressure block 30 applies pressure to the clamping plate 18. The clamping plate 18 forms pressure on the movable rod 21 to prevent the movable rod 21 and the suction cup 24 from moving during workpiece processing. After the adjustment is completed, a locking force is applied to the second threaded rod 28 through the first locking nut to prevent the second threaded rod 28 from being accidentally touched.

[0054] like Figure 2 As shown, in this embodiment, the fixture for processing carbon fiber composite materials also includes: an adjustment component for adjusting the rotation angle of the bracket 17; specifically, the adjustment component includes: a box body 9 arranged at the lower end of the support platform 3; a worm 10 rotatably arranged in the box body 9; a worm wheel 13 matched with the worm 10; a second handle 11 connected to one end of the worm 10, the second handle 11 matches with a first through slot 12 opened in the box body 9, and the surface of the second handle 11 is provided with an external thread; a second locking nut for locking the second handle 11; a rotating shaft 14 connected to the worm wheel 13, the rotating shaft 14 passes through a second through slot 15 opened on the surface of the support platform 3; a connecting rod 16 connected to the bracket 17 at one end, and the other end of the connecting rod 16 is connected to the rotating shaft 14;

[0055] The above technical solution can be used to adjust the rotation angle of the bracket 17. When in use, the second rotating handle 11 is rotated to drive the worm 10 to rotate, the worm 10 drives the worm wheel 13 to rotate, the worm wheel 13 drives the connecting rod 16 to rotate, the connecting rod 16 drives the bracket 17 to rotate, and the bracket 17 drives the movable rod 21 and the suction cup 24 to rotate, thereby achieving adjustment. After the adjustment is completed, the second rotating handle 11 can be locked using the second locking nut to prevent accidental touch.

[0056] like Figure 1 and Figure 5As shown, in this embodiment, the fixture for processing carbon fiber composite materials also includes: a base 1 with a mounting hole 2, and the base 1 is provided with an adjustment component for adjusting the height of the support platform 3; specifically, the adjustment component includes: a first threaded rod 6 with one end arranged at the lower end of the support platform 3; a sleeve 7 arranged at the upper end of the base 1; a nut sleeve 8 threadedly matched with the first threaded rod 6, and the nut sleeve 8 is rotatably arranged at the top of the sleeve 7; a guide component for guiding the lifting direction of the support platform 3; specifically, the guide component includes a plurality of guide parts, and the guide part includes: a guide rod 4 with one end connected to the bottom end of the support platform 3; a guide cylinder 5 slidably matched with the guide rod 4, and the guide cylinder 5 is arranged at the upper end of the base 1;

[0057] The above technical solution can be used to conveniently adjust the height of the support platform 3. When in use, the first threaded rod 6 can be driven to rise and fall in the sleeve 7 by rotating the nut sleeve 8, thereby adjusting the height of the support platform 3. Since the guide rod 4 and the guide cylinder 5 are provided, it is possible to avoid the first threaded rod 6 and the support platform 3 from rotating synchronously when the nut sleeve 8 is rotated, thereby improving the stability of the structure.

[0058] Working principle: When in use, first place the workpiece on the suction cup 24, rotate the movable rod 21 to make it rotate in the movable groove of the bracket 17. When rotating, the rotating column 22 of the movable rod 21 rotates around the rotating groove 19. At the same time, the sliding column 23 slides along the arc groove 20, thereby realizing the angle adjustment of the movable rod 21. Since the splint 18 is provided, the splint 18 can keep in contact with the movable rod 21 under the action of the elastic structure, thereby forming a large damping effect on the movable rod 21 to prevent the workpiece from pressing the movable rod 21. Therefore, there is no need to manually press the movable rod 21 to prevent it from moving, and the operation is relatively convenient. After manually adjusting the angle of the movable rod 21 to an appropriate level, the driving assembly is controlled so that the splint 18 applies a tightening force to the movable rod 21, thereby fixing the movable rod 21 and completing the angle adjustment.

[0059] Thereby completing a series of tasks, the contents not described in detail in this specification belong to the prior art known to professional and technical personnel in this field.
