The first support body 12 can be turned over in a vertical plane by the driving of the first rotation mechanism 111 to change the orientations of the first front clamping piece 13 and the first back clamping piece 14 so as to adapt to workpieces of different types. For example, as in the examples of fig. 1 to 3, the workpiece 3 is in particular a positive T-shaped workpiece, and the first front clamping member 13 on the first support body 12 is disposed upward and clamped in cooperation with the workpiece head 31; as in the examples of fig. 4 and 5, the workpiece 3 is embodied as an L-shaped workpiece, and the first back clamping member 14 on the first support body 12 is disposed upward and clamped in cooperation with the workpiece head 31.

In addition, the specific number of the positioning pins 131 and the specific positions on the first support body 12 may be set according to the model size of the workpiece to be processed. Through the design of the positioning pin 131, the first front clamping piece 13 can be adapted to workpieces with different sizes, and the universality is higher.

The positioning pins 131 may be detachably disposed in the positioning mounting holes 122 according to the specific use requirement, for example, in one specific manner, when in use, the positioning pins 131 are installed in the positioning mounting holes 122 according to the alignment condition of the positioning matching holes of the workpiece head 31 and the positioning mounting holes 122, and the positioning pins 131 in the positioning mounting holes 122 which are aligned are taken out from the positioning mounting holes 122 which are not aligned; in another specific manner, as shown in an example in fig. 7, a positioning pin telescopic mechanism 133 is provided in each positioning mounting hole 122, a positioning pin 131 is connected to a telescopic end of the positioning pin telescopic mechanism 133, and the positioning pin 131 can be driven to move up and down by telescopic movement of the positioning pin telescopic mechanism 133 so as to extend outwards or retract inwards relative to the positioning mounting holes 122, and when in use, the positioning pin 131 in the aligned positioning mounting holes 122 is extended to be matched with the positioning matching holes of the workpiece heads 31 according to the alignment condition of the positioning matching holes of the workpiece heads 31 and the positioning mounting holes 122, and the positioning pin 131 in the non-aligned positioning mounting holes 122 is retracted so as to prevent interference with the workpiece heads 31. The positioning pin telescoping mechanism 133 may specifically be an oil cylinder, an electric cylinder, an air cylinder or other mechanisms capable of realizing telescoping motion.

Taking fig. 7 and 8 as an example, the number of the positioning pins 131 may be four, and two by two, and one by two, are respectively disposed on the first supporting body 12 near the left and right ends. When the positioning pin 131 is matched with the workpiece head 31, at least two positioning pins 131 can be adopted to jointly match with the workpiece head 31 according to the positions of the positioning matching holes, and particularly, various different combination modes can be adopted, for example, the positioning pin 131 at the outer side of the left end and the positioning pin 131 at the inner side of the right end simultaneously extend, or the positioning pin 131 at the inner side of the left end and the positioning pin 131 at the outer side of the right end simultaneously extend, or the positioning pin 131 at the inner side of the left end and the positioning pin 131 at the inner side of the right end simultaneously extend, or the positioning pin 131 at the outer side of the left end and the positioning pin 131 at the outer side of the right end simultaneously extend, and the principle is similar and is not listed.

The specific number and specific positions of the first side clamping structures 132 may be set according to actual machining requirements, for example, in fig. 7 and fig. 9, four first side clamping structures 132 may be set, and two pairs of first side clamping structures 132 are disposed opposite to each other, and are respectively located on two sides of the rotation axis of the first support body 12, so as to help make stress more uniform when the workpiece head 31 is clamped.

In a further embodiment of the present utility model, as shown in fig. 5, 6 and 10, the first back clamping member 14 includes two positioning plates 141 and two first telescopic mechanisms 142. The two positioning plates 141 are vertically disposed on the bottom surface of the first support body 12, and in the second horizontal direction, the two positioning plates 141 are respectively located near the left and right end surfaces of the first support body 12. Correspondingly, the two first telescopic mechanisms 142 are arranged on one side of the first support body 12 in the first horizontal direction, the two first telescopic mechanisms 142 are arranged in opposite directions and are respectively positioned on two sides of the rotation axis of the first support body 12, and each first telescopic mechanism 142 can be matched with the positioning plates 141 on two sides to clamp the workpiece head 31. The distance between the two positioning plates 141 and the corresponding end surfaces on the first support 12 is different, as in the example in fig. 10, one positioning plate 141 located on the first support 12 near the left end is located at a distance L1 from the end surface on the same end of the first support 12, and one positioning plate 141 located on the first support 12 near the right end is located at a distance L2 from the end surface on the same end of the first support 12, where L2 is greater than L1, and when in use, one of the positioning plates 141 can be selected as a positioning reference according to the difference of the lateral dimensions of the workpiece head 31, so that the side wall on the corresponding side of the workpiece head 31 abuts against the positioning plate 141, and then the first telescopic mechanism 142 on the other side extends to abut against the side wall on the other side of the workpiece 3, and applies pressure to cooperate with the positioning plate 141 to clamp the workpiece 3 through the first telescopic mechanism 142.

It should be noted that, the first telescopic mechanism 142 may specifically be an oil cylinder, an electric cylinder, an air cylinder, or other mechanisms capable of implementing telescopic motion.

Further, as shown in fig. 5, 10 and 11, the first back clamping member 14 further includes a first lifting pressing mechanism 143. The first lifting pressing mechanism 143 is provided at one side of the first supporting body 12 for pressing the top surface of the workpiece head 31.

Specifically, the specific number and specific positions of the first lifting and pressing mechanisms 143 may be set according to actual processing requirements, for example, as illustrated in fig. 10, three first lifting and pressing mechanisms 143 may be set, one of which is disposed on the first support 12 at a position close to the rotation axis, that is, at a position close to the center, the other two are respectively located on the left and right sides, and the three first lifting and pressing mechanisms 143 are disposed at intervals in the second horizontal direction to perform pressing operations on different positions on the top surface of the workpiece head 31.

It should be noted that the rotational connection between the first pressing structure 1432 and the first lifting mechanism 1431 may take different forms, for example, the first pressing structure 1432 may be configured to rotate relative to the first lifting mechanism 1431 in a horizontal plane, or the first pressing structure 1432 may be configured to rotate relative to the first lifting mechanism 1431 in a vertical plane. When the workpiece 3 is lifted, the first pressing structure 1432 is rotated to a position far away from the first supporting body 12 so as to prevent blocking interference on the workpiece 3, after the workpiece 3 is lifted, the first pressing structure 1432 is rotated to a corresponding working position, and the height of the first pressing structure 1432 is adjusted through the first lifting mechanism 1431 so that the first pressing structure 1432 is abutted against the top surface of the workpiece head 31 for pressing.

In a further embodiment of the present utility model, as shown in fig. 1, 2 and 12, the tail clamp device 2 includes a horizontal movement mechanism 21, a second body 22, and a second support 23. The horizontal movement mechanism 21 is provided as a mounting base along a first horizontal direction; the second body 22 is disposed on the horizontal movement mechanism 21, and the second body 22 can move in the first horizontal direction under the driving of the horizontal movement mechanism 21 to adjust the interval between the second body 22 and the first body 11 of the head clamp device 1 to adapt to workpieces with different length sizes. The horizontal movement mechanism 21 may specifically be a linear motor or other linear movement mechanism. The second body 22 is provided with a second rotation mechanism 221, and the second support 23 is disposed on a side of the second body 22 facing the first support 12 and is connected to the second rotation mechanism 221, for example, through a second connection flange 231 as shown in fig. 2, to the second rotation mechanism 221, so that the second support 23 can rotate in a vertical plane under the driving of the second rotation mechanism 221 to cooperate with the first support 12 to perform a tilting operation on the workpiece 3. The second supporting body 23 is provided with a main lifting mechanism 24 and a second clamping piece 25, the second clamping piece 25 is connected to the main lifting mechanism 24, the second clamping piece 25 can lift under the motion of the main lifting mechanism 24 so as to adjust the height of the second clamping piece 25, and the second clamping piece 25 can clamp the tail portion 32 of the workpiece and is matched with the first front clamping piece 13 or the first back clamping piece 14 of the head clamp device 1 to jointly realize the clamping operation on the workpiece 3.

Through the scheme in this embodiment, after the head clamp device 1 and the tail clamp device 2 of the clamp tool 100 are installed, the distance between the first support body 12 and the second support body 23 can still be adjusted through the horizontal movement mechanism 21, so that workpieces with different length sizes can be adapted, and after the first support body 12 is turned over, the height of the second clamping piece 25 can be adjusted through the main lifting mechanism 24, so that the height of the first front clamping piece 13 or the first back clamping piece 14 is adapted, and the universality and the compatibility of the clamp tool 100 are stronger.

It will be appreciated that, due to the different structures of the first front clamping member 13 and the first back clamping member 14 on the first support body 12, when the first support body 12 is turned over to a state in which the first front clamping member 13 faces upward or the first back clamping member 14 faces upward, the same working height is not necessarily maintained, and the second clamping member 25 can be adjusted in height correspondingly by the main lifting mechanism 24 so as to adapt to the height of the first front clamping member 13 or the first back clamping member 14, so that the workpiece 3 can be kept in a horizontal state for performing corresponding machining operations.

Further, as shown in fig. 12 and 13, the second clamping member 25 includes a lateral movement mechanism 251, two lateral clamping structures 252, and a support table 253. The transverse movement mechanism 251 is disposed along the second horizontal direction and connected to the main lifting mechanism 24, so as to perform lifting movement under the driving of the main lifting mechanism 24; the second water direction is perpendicular to the first horizontal direction, i.e. the first horizontal direction is understood to be longitudinal and the second horizontal direction is understood to be transverse, based on the orientation of the workpiece 3.
