Detailed Description

In order to make the technical problems, technical schemes and beneficial effects to be solved more clear, the invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the invention.

Referring to fig. 1 to 7, a description will now be given of a multifunctional component fixing apparatus according to the present invention. The multifunctional component fixing device comprises a workbench 200 for placing a component 100, a transverse clamping mechanism 300 for providing a transverse clamping force for the component 100, a vertical clamping mechanism 400 for providing a vertical clamping force for the component 100, and a flexible clamping mechanism 500 for flexibly clamping the component 100; the table 100 includes a center plate 210 and a plurality of circumferential plates 220 disposed along the circumference of the center plate 100, and the center plate 210 and the circumferential plates 220 are respectively connected with different elevating mechanisms 230; at least one of the peripheral plates 220 and the corresponding lifting mechanism 230 are provided with a turnover mechanism 240, so that the plate surface of the peripheral plate 220 can be turned from the plate surface horizontal state to the direction of the central plate 210 to the plate surface vertical state by the turnover mechanism 240, and the plate surface horizontal state and the plate surface vertical state can be switched.

Compared with the prior art, the multifunctional component fixing device provided by the embodiment has the following beneficial effects:

For the component 100 placed on the workbench 200, the mode of mutual matching of transverse clamping, vertical clamping and flexible clamping can be adopted, the fixing direction is selected in various ways, the adaptability selection can be carried out according to components with different shapes, and the application range and the reliability of the fixing device are enlarged.

2. By adopting the mode that the central plate 210 and the circumferential plate 220 are respectively lifted, the central plate 210 can be higher than the circumferential plate 220 in height, the circumferential plate 220 can be kept away, more processing space can be exposed, as shown in the state of fig. 6, the processing reserved space is effectively increased, and the processing difficulty is reduced.

3. By imparting a turnover function to at least one of the peripheral plates 220, the turnover of the member 100 placed on the table 100, for example, the turnover of the member 100, can be controlled by controlling the turnover state of the peripheral plate 220, and the table 200 is controlled to be switched from the state of fig. 5 to the state of fig. 4 without requiring an operator to perform manual turnover, thereby reducing the labor intensity.

As a way of assembling the lifting mechanism 230 with the center plate 210 and the circumferential plate 220, the lifting ends may be formed as a bracket structure having a large area (as shown in fig. 4 to 6), providing a sufficient installation space for the center plate 210, the circumferential plate 220, and the structure for controlling inversion. The power portion of the lifting mechanism 230 may be a cylinder, a hydraulic cylinder, a linear driving motor, or the like, which is not limited herein.

In specific implementation, the required circumferential plate 220 is determined according to the size of the cross section of the component 100, and the non-adaptive circumferential plate 220 moves downwards under the drive of the corresponding lifting mechanism 230, so that more operation space is provided for component processing; also, the adapted circumferential plate 220 may satisfy the movement and flipping function of the member 100 through flipping of the circumferential plate 220. For a component 100 with less space requirements to operate, all of the circumferential plates 220 may be moved upward to be flush with the center plate 210, which cooperate to provide a greater support plane.

In some embodiments, referring to fig. 1 to 6, considering applicability of the placement space, the workbench 200 is set to be square, corresponding to two circumferential plates 220, which are both "U" shaped members, and after the two circumferential plates 220 are spliced, a "back" frame is formed, where a central plate 210 is disposed in a middle hollow position of the frame, and the splicing position of the two circumferential plates 220 is the position where the rotating shaft of the circumferential plate 220 that can be turned is located. It should be understood that the shape of the workbench 200 and the docking manner of the circumferential plate 220 may meet the actual working requirements and the assembly requirements, which are not limited herein.

In addition, in the present embodiment, the number of the reversible circumferential plates 220 is exemplarily shown as one, but it is of course possible to provide all the circumferential plates 220 with the reversing function, or some of the circumferential plates 220 with the reversing function, and the specific arrangement is not limited herein.

In some embodiments, referring to fig. 1-7, the center plate 210 includes a center core 211 and a plurality of center webs 212 circumferentially disposed along the center core 211, the center core 211 having a first suction attachment mechanism 250 disposed thereon; the center coamings 212 are in one-to-one correspondence with the circumferential plates 220, the center coamings 212 corresponding to the circumferential plates 220 connected with the turning mechanisms 240 are hinged with the lifting mechanisms 230 corresponding to the center coamings 212, and follow-up limiting structures are arranged between the center coamings 212 and the corresponding circumferential plates 220 so that the center coamings 212 and the corresponding circumferential plates 220 can turn synchronously. In particular, the first adsorption fixing mechanism 250 is a vacuum adsorption mechanism, such as a vacuum chuck connected with an air pump.

In this embodiment, the layout of the center core plate 211 and the center shroud 212 is similar to that of the center plate 210 and the circumferential plate 220, and since the center shroud 212 can be turned over along with the circumferential plate 220, the turning contact area with the member 100 is increased, so that the turning operation is smoother. Meanwhile, in the present embodiment, the space of the center plate 210 is fully utilized, and the first adsorption fixing mechanism 250 is disposed on the center plate 211 thereof, so that each clamping mechanism can be assisted in processing, and the reliability of fixing is improved by adsorbing the member 100, so as to ensure the processing precision, or the member 100 (for example, a member with a smaller volume) which cannot be effectively clamped by each clamping mechanism is fixed; in addition, through the mode of vacuum adsorption, the unstable problem of fixation can be avoided through the mode of adsorption fixation under the condition that the surface part of the component is smooth, and the flexible contact between the component 100 and the workbench 200 can be realized, so that the component is prevented from being knocked and damaged.

More specifically, the circumferential plate 220 to which the turning mechanism 240 is connected is rotatably connected to the corresponding lifting mechanism 230, and a damping rebound member is provided at a rotation shaft of the circumferential plate 220, and the damping rebound member is configured with a pre-tightening force for keeping the plate surface of the corresponding circumferential plate 220 horizontal. When the circumferential plate 220 is turned from the vertical to the horizontal state, the damping rebound member can assist the circumferential plate 220 to reset, enhancing the reliability of the reset.

When the circumferential plate 220 is required to be overturned in a vertical state, the overturning motor 241 drives the overturning bracket 242 to overturn, and the overturning bracket 242 drives the circumferential plate 220 to overturn in the process of contacting with the circumferential plate 220; the reverse operation can realize the turnover switching of the circumferential plate 220 to the horizontal state under the elastic reset action of the damping elastic piece. The turnover mechanism 240 of the embodiment does not need to have a substantial connection relationship with the circumferential plate 220, so that the connection mode between the turnover mechanism 240 and the circumferential plate 220 is greatly simplified, the arrangement of a huge connection guide structure is avoided, and the failure rate is greatly reduced.

As one embodiment of the stopper structure, the side of the circumferential plate 220 facing the center plate 210 is formed with a first stopper step. The corresponding center coaming 212 is provided with a second limiting step, and the two limiting steps are mutually clamped and matched, so that limiting can be realized; if the center plate 210 is required to be lifted relative to the circumferential plate 220, the first limit step and the second limit step do not block each other, and the circumferential plate 220 can be lowered or the center plate 210 can be lifted.

The two opposite sides of the working table 200 along the second horizontal direction are respectively provided with a flexible clamping mechanism 500, and the flexible clamping mechanism 500 reciprocates along the vertical direction through a third guiding mechanism arranged at the side of the working table 200.

The lateral clamping mechanism 300 can flexibly adjust the position at the side of the workbench 200 under the drive of the first guiding mechanism 600, and then flexibly change clamping points are provided in the second horizontal direction according to different components 100; driven by the second guiding mechanism 700, the vertical clamping mechanism 400 can flexibly adjust the position at the side of the workbench 200, and then provide flexibly changed clamping points in the first horizontal direction according to different components 100; meanwhile, the third guiding mechanism enables the flexible clamping mechanism 500 to be lifted, then to descend for avoiding in the moving process of the vertical clamping mechanism 400, and when the flexible clamping mechanism 500 is required to clamp, the height of the flexible clamping mechanism 500 can be adjusted adaptively according to different components 100. According to the embodiment, the space around the workbench is reasonably utilized, flexible transformation of the positions of the transverse clamping, the vertical clamping and the flexible clamping is realized, then clamping points can be flexibly selected according to different components 100, the transverse clamping mode, the vertical clamping mode and the flexible clamping mode can be independently used or combined for use, and the flexibility and the applicability of component fixing are greatly improved.

Meanwhile, since the second adsorption fixing mechanism 340 is provided, the lateral clamping plate 320 can be assisted in processing, and the reliability of fixing can be improved by adsorbing the member 100; in addition, through the vacuum adsorption mode, the problem of unstable fixation can be avoided through the adsorption fixation mode under the condition that the surface part of the component is flat, and the flexible contact between the component 100 and the transverse clamping plate 320 can be realized, so that the component 100 is prevented from being knocked and damaged.

In some embodiments, referring to fig. 16, a plurality of position sensors 800 are further disposed on one side of the table 200 and distributed in a straight line, and the plurality of position sensors 800 are symmetrically disposed along the central axis of the table 200, and the position sensor 800 of this embodiment can determine whether the component positions are aligned by sensing the distance between the component side walls and the sensor columns.

In this embodiment, the number of the position sensors 800 is four, which are defined as a position sensor a, a position sensor B, a position sensor C, and a position sensor D, respectively, taking the processing of the quadrangular prism-shaped member 100 as an example, the predetermined placement position needs to make the central axis of the member 100 face the central axis of the table 200, and the plurality of position sensors 800 are distributed along the second horizontal direction.

After the component 100 is placed on the workbench 200, if the placement position is not the predetermined position (as shown in fig. 16), the position sensor a, the position sensor B, the position sensor C and the position sensor D respectively acquire distance information of the side surface of the component 100, in the predetermined state, the distance information acquired by all the sensors should be consistent with the predetermined value (or be within the predetermined error range), but in the attached state, the distance information acquired by the position sensor a and the position sensor B is obviously much smaller than the predetermined value, and the distance information acquired by the position sensor C and the position sensor D is obviously much larger than the predetermined value, so that the placement position deviation of the component 100 can be determined; then, the control unit obtains the deflection degree according to the predetermined placement data, and controls the transverse clamping mechanisms 300 on both sides to perform synchronous or asynchronous expansion and contraction to adjust the position of the component 100.

It should be understood that the position sensor 800 may be disposed around the table 200, obtain actual position information of the component 100 according to actual processing conditions, determine whether the component 100 is deflected according to the actual position information, and then control the transverse clamping mechanism 300 to adaptively stretch and retract to adjust the position of the component 100.
