[0007] Furthermore, a plurality of clamping structures for clamping the parts to be processed are installed on the bridge plate tooling, and the plurality of clamping structures are respectively located on two opposite sides of the positioning transition plate.

[0008] Furthermore, the clamping structure includes a screw rod supported on the bridge plate fixture, and a pressing block for pressing the part to be processed is installed on the upper end of the screw rod.

[0009] Furthermore, the bridge plate tooling is provided with a plurality of mounting holes for mounting the processing mechanism.

[0010] Furthermore, a groove is provided on the bridge plate tooling, and a protrusion which is plugged and matched with the groove is provided on the positioning transition plate.

[0011] Furthermore, the inner side surfaces of the two turntables are provided with support seats, and the two ends of the bridge plate tooling are respectively supported and fixed on the two support seats.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings and implementation examples. It is to be understood that the specific implementation examples described herein are only used to explain the relevant content, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention are shown in the accompanying drawings.

[0024] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0025] like Figure 1 , Figure 2 , Figure 3 As shown, the utility model provides a tooling that can process multiple surfaces after one clamping, including two relatively arranged turntables 3, both of which are supported by supports, and there is a certain distance between two adjacent turntables 3, one of which is equipped with a power device for driving the turntable 3 to rotate, and the turntable 3 is driven to rotate by the power device, and the power device can be a motor, and the turntable 3 is driven to rotate by a gear transmission structure, a belt transmission structure, a chain transmission structure, etc., and a bridge plate tooling 4 is connected between the two turntables 3, and the bridge plate tooling 4 is plate-shaped, and the bridge plate tooling 4 is wide at both ends and narrow in the middle, so that the contact area between the two ends of the bridge plate tooling 4 and the turntable 3 is larger, so as to ensure that the installation of the two ends of the bridge plate tooling 4 is more stable.

[0026] The bridge plate fixture 4 is also equipped with a positioning transition plate 5, which is used to install the parts to be processed. In order to facilitate the processing of the parts to be processed, the positioning transition plate 5 can be located in the center of the bridge plate fixture 4. In order to ensure that the parts to be processed installed on the positioning transition plate 5 are more stable, a pull rod 6 is also installed on the bridge plate fixture 4. The pull rod 6 is located in the center of the bridge plate fixture 4, and the lower end of the pull rod 6 passes through the positioning transition plate 5 and the bridge plate fixture 4 and extends downward, and is locked and fixed with the bridge plate fixture 4 by a nut. An upper pressure plate 7 is also installed on the upper end of the pull rod 6. The position of the upper pressure plate 7 on the pull rod 6 can be adjusted up and down. When the parts to be processed are installed on the positioning transition plate 5, the upper pressure plate 7 is pressed on the parts to be processed, and finally the upper pressure plate 7 is locked by a nut, so that the parts to be processed are fixed between the positioning transition plate 5 and the upper pressure plate 7, and the parts to be processed are pressed and fixed.

[0027] In the utility model, the positioning transition plate 5 is circular, and the upper diameter of the positioning transition plate 5 is smaller than the lower diameter of the positioning transition plate 5, so that the positioning transition plate 5 has an annular step surface, so that after the part to be processed is installed on the positioning transition plate 5, the part to be processed can be positioned by cooperating with the upper part of the positioning transition plate 5 and the lower part of the positioning transition plate 5, which not only ensures that the part to be processed remains vertical, but also ensures that the central axis of the part to be processed and the central axis of the pull rod 6 are in the same straight line, thereby ensuring the centrality of the part to be processed; at the same time, the upper pressure plate 7 is also circular, and the upper pressure plate 7 can be used to horizontally limit the upper end of the part to be processed while pressing and fixing the part to be processed, so as to make the position accuracy of the part to be processed higher.

[0028] The bridge plate fixture 4 is also equipped with a plurality of clamping structures, which are used to clamp the upper edge of the part to be processed, thereby assisting in clamping the part to be processed. In order to ensure that the pressure applied by the plurality of clamping structures can be evenly distributed on the part to be processed, the plurality of clamping structures are evenly distributed on the opposite sides of the positioning transition plate 5. Specifically, the plurality of clamping structures are divided into two groups, and the two groups of clamping structures are respectively located at the two ends of the bridge plate fixture 4, so that the installation of the part to be processed is more stable, and the parts are more accurate after processing.

[0029] The clamping structure includes a screw rod 8 supported on the bridge plate fixture 4, the lower end of the screw rod 8 is fixed to the bridge plate fixture 4, and the upper end of the screw rod 8 is provided with a pressing block 9 for pressing the part to be processed. The position of the pressing block 9 on the screw rod 8 can be adjusted in height. When the part to be processed is mounted on the positioning transition plate 5, the pressing block 9 is pressed on the part to be processed, and then the pressing block 9 is locked by a nut, thereby further pressing the part to be processed.

[0030] The bridge plate fixture 4 is provided with a plurality of mounting holes 42, all of which are used to mount the processing mechanism, and the mounting holes 42 are long waist holes, and the axial direction of the mounting holes 42 is consistent with the radial direction of the positioning transition plate 5. When it is necessary to install a processing mechanism for processing the parts to be processed, a bolt can be provided at the lower end of the processing mechanism, and the lower end of the bolt is passed through the mounting hole 42 and then locked and fixed by a nut. When it is necessary to adjust the position of the processing mechanism, the nut on the bolt is loosened to move the processing mechanism along the axial direction of the mounting hole 42. When the processing mechanism is adjusted, the nut on the bolt can be tightened, thereby fixing the processing mechanism on the bridge plate fixture 4.

[0031] In order to ensure the installation accuracy of the positioning transition disc 5, a groove 41 is also provided on the upper surface of the bridge plate tooling 4, and a protrusion 51 matching the groove 41 is provided on the lower surface of the positioning transition disc 5, so that when the positioning transition disc 5 is installed, the protrusion 51 is inserted into the groove 41 to realize the positioning of the positioning transition disc 5, so that the position accuracy of the positioning transition disc 5 is higher. In the present utility model, the groove 41 and the protrusion 51 can be circular, triangular, polygonal, etc., and the protrusion 51 and the groove 41 are clearance-matched; at the same time, in the present utility model, while ensuring that the protrusion 51 on the positioning transition disc 5 of different sizes can be inserted into the groove 41, the groove 41 and the protrusion 51 can also be multiple, and the protrusion 51 can also be located at the center or edge of the positioning transition disc 5. In addition, in the present utility model, the groove 41 can also be provided on the lower surface of the positioning transition disc 5, and the protrusion 51 can be provided on the bridge plate tooling 4.

[0032] The inner side surfaces of the two turntables 3 are both provided with support seats, which are in the shape of long strips. The length of the support seats is adapted to the width of the ends of the bridge deck tooling 4. When the bridge deck tooling 4 is installed, the two ends of the bridge deck tooling 4 are first supported on the support seats, and then the ends of the bridge deck tooling 4 are fixed to the support seats with screws, which not only ensures the stability of the bridge deck tooling 4, but also facilitates the installation and disassembly of the bridge deck tooling 4.

[0033] The tooling provided by the utility model that can process multiple surfaces after one clamping also includes a base plate 2 that can be installed on a CNC machine tool workbench 1 or other similar equipment workbench 1, and two turntables 3 are fixed on the base plate 2 by screws.

[0034] When it is necessary to process the part to be processed, the upper pressure plate 7 is removed from the pull rod 6, and the nut of the locking pressure block 9 is loosened to rotate the pressure block 9 outward. Then, the part to be processed is installed on the positioning transition plate 5, and the upper pressure plate 7 is installed on the screw 8. The nut that locks the upper pressure plate 7 is tightened, and the upper pressure plate 7 is pressed on the part to be processed. At the same time, the pressure block 9 is rotated to rotate the pressure block 9 to the part to be processed, and the nut that locks the pressure block 9 is tightened, and the pressure block 9 is pressed on the part to be processed; finally, when the CNC machine tool processes the part to be processed fixed between the positioning transition plate 5 and the upper pressure plate 7, the power device drives one of the turntables 3 to rotate, so that the bridge plate tooling 4 installed between the two turntables 3 can rotate 360°, so that the part to be processed installed between the positioning transition plate 5 and the upper pressure plate 7 is rotated, thereby realizing multi-faceted automated CNC processing of the part to be processed after one clamping is completed, improving processing efficiency, processing quality, degree of automated processing, processing safety, and reducing processing costs.
