[0029] See Figure 1The CNC machine tool processing unit 1 provides installation space for the plate changing unit 2, the first vise unit 3, the dual-station unit 4, and the second vise unit 5.

[0030] See Figure 1 Any one of the following components—plate changing unit 2, first vise unit 3, dual-station unit 4, and second vise unit 5—can be freely combined with the CNC machine tool processing unit 1 to form a clamping device for holding workpieces.

[0031] See Figure 2 The CNC machine tool processing unit 1 includes a worktable 11. A four-axis drive device 12 and a tailstock positioning mechanism 13 are symmetrically arranged on the top of the worktable 11. A bridge plate structure 14 is arranged in the middle of the four-axis drive device 12 and the tailstock positioning mechanism 13.

[0032] The four-axis drive device 12 is a servo motor driven rotary axis assembly, and the tailstock positioning mechanism 13 is an auxiliary support and locking assembly that works with the four-axis drive device 12. The bridge plate structure 14 can be fixedly installed through the tailstock positioning mechanism 13 and the four-axis drive device 12. Furthermore, the tailstock positioning mechanism 13 can also adjust the position of the bridge plate structure 14 by cooperating with the four-axis drive device 12 to meet the needs of multi-angle processing.

[0033] The bridge plate structure 14 provides installation positions for the plate changing unit 2, the first vise unit 3, the dual-station unit 4, and the second vise unit 5, facilitating their installation. By cooperating with the plate changing unit 2, the first vise unit 3, the dual-station unit 4, and the second vise unit 5, the bridge plate structure 14 enables rapid mold changing of the clamping tools, forming a connection between the clamps, improving mold changing efficiency, and reducing the workload of operators.

[0034] See Figure 3 and Figure 4 The bridge plate structure 14 includes a bridge plate body 141, on which a second mounting hole group 143, a first mounting hole group 142, a third mounting hole group 144, and a fourth mounting hole group 145 are sequentially provided. See Figure 3 and Figure 4 The second mounting hole group 143 and the third mounting hole group 144 are located on the top of the bridge plate body 141, and the first mounting hole group 142 and the fourth mounting hole group 145 are located on the bottom of the bridge plate body 141.

[0039] Mounting holes 4, 7, and 10 have the same structure as mounting hole 1 (1421); mounting holes 5, 8, and 11 have the same structure as mounting hole 2 (1422); and mounting holes 6, 9, and 12 have the same structure as mounting hole 3 (1423). This means that plate changing unit 2, first vise unit 3, dual-station unit 4, and second vise unit 5 can be correspondingly positioned at the first mounting hole group 142, second mounting hole group 143, third mounting hole group 144, and fourth mounting hole group 145 for rapid installation, achieving the purpose of rapid mold changing. Furthermore, by setting multiple sets of mounting holes, various fixtures can be adapted to meet the needs of multiple product types.

[0040] See Figure 2 and Figure 5 The plate changing unit 2 includes a plate changing body 21. The bottom of the plate changing body 21 is provided with two sets of fixing posts 23. The two sets of fixing posts 23 can be installed at the positions of the second mounting hole group 143 and the third mounting hole group 144.

[0041] The second mounting hole group 143 includes mounting hole four, mounting hole five, and mounting hole six in sequence, and the third mounting hole group 144 includes mounting hole seven, mounting hole eight, and mounting hole nine in sequence. The two sets of fixing posts 23 are respectively adapted to mounting hole five and mounting hole eight, that is, the two sets of fixing posts 23 can be fixedly installed at the positions of mounting hole five and mounting hole eight. After the two sets of fixing posts 23 are installed at the positions of the second mounting hole group 143 and the third mounting hole group 144, the tool to be processed can continue to be placed on the plate changing body 21 to meet the needs of CNC machining.

[0042] Furthermore, since the structures of mounting holes five, eight, eleven and two (1422) are identical, the two sets of fixing posts 23 can also be installed at the positions of mounting holes eleven and two (1422). That is, the two sets of fixing posts 23 can be fixedly installed at the positions of the first mounting hole group 142 and the fourth mounting hole group 145 to meet the needs of production and processing.

[0043] See Figure 2 and Figure 6 The first vise unit 3 includes a first vise body 31. A fixed shaft 32 is provided at the bottom of the first vise body 31. The fixed shaft 32 can be installed at any position of the second mounting hole group 143 or the third mounting hole group 144.

That is, the fixed shaft 32 can be fixedly installed at any one of the mounting holes five, eight, eleven, and two 1422. The first vise unit 3 can be installed at any one of the first mounting hole group 142, the third mounting hole group 144, and the fourth mounting hole group 145. By setting the first vise unit 3, it can be installed at multiple positions to meet the needs of multi-variety production and processing.

[0045] See Figure 2 and Figure 7 The dual-station unit 4 includes a placement platform 41. The bottom of the placement platform 41 is provided with two sets of positioning posts 42 and four sets of mounting posts 43. The two sets of positioning posts 42 can be placed at the positions of the second mounting hole group 143 and the third mounting hole group 144. The four sets of mounting posts 43 can be installed at the positions of the second mounting hole group 143 and the third mounting hole group 144 by plugging in.

[0046] The second mounting hole group 143 includes mounting hole four, mounting hole five, and mounting hole six in sequence, and the third mounting hole group 144 includes mounting hole seven, mounting hole eight, and mounting hole nine in sequence. Two sets of positioning posts 42 are adapted to mounting hole five and mounting hole eight respectively. The two sets of positioning posts 42 can be placed at the positions of mounting hole five and mounting hole eight. At this time, the two sets of positioning posts 42 can perform preliminary positioning of the placement platform 41, which facilitates the positioning and installation of the placement platform 41. Four sets of mounting posts 43 are adapted to mounting hole four, mounting hole six, mounting hole seven, and mounting hole nine respectively. The four sets of mounting posts 43 can be fixedly installed at the positions of mounting hole four, mounting hole six, mounting hole seven, and mounting hole nine by plugging in, and the placement platform 41 is fixedly installed in this way. That is, by setting two sets of positioning posts 42 and four sets of mounting posts 43, the placement platform 41 can be fixedly installed at the positions of the second mounting hole group 143 and the third mounting hole group 144, thereby realizing the installation of the placement platform 41.

[0047] Furthermore, since the structures of mounting holes five, eight, and eleven are identical to those of mounting hole two 1422, the two sets of positioning posts 42 can also be placed at the positions of mounting holes two 1422 and eleven. The structures of mounting holes five, eight, and eleven are identical to those of mounting hole two 1422, and the structures of mounting holes six, nine, and twelve are identical to those of mounting hole three 1423. The four sets of mounting posts 43 can also be inserted and installed at the positions of mounting holes three 1423, one 1421, six, and twelve, thereby enabling multi-directional installation and fixing, suitable for installation in multiple positions.

[0048] In addition, the dual-station unit 4 is equipped with two sets of processing stations. After the dual-station unit 4 is installed, two sets of workpieces can be placed on the dual-station unit 4 for processing.

[0049] See Figure 2 and Figure 8 The second vise unit 5 includes a second vise body 51. The bottom of the second vise body 51 is provided with four sets of fixing holes 52. Two sets of limiting posts 53 are provided in the middle of the four sets of fixing holes 52. The two sets of limiting posts 53 can be placed at the positions of the first mounting hole group 142 and the fourth mounting hole group 145.

[0050] Among them, the two sets of limiting posts 53 are respectively adapted to the mounting hole 1422 and mounting hole 11. The two sets of limiting posts 53 can be placed at the positions of mounting hole 1422 and mounting hole 11 for positioning. After the two sets of limiting posts 53 are positioned, the four sets of fixing holes 52 correspond to mounting hole 1421, mounting hole 3423, mounting hole 10 and mounting hole 12 respectively. The four sets of fixing holes 52 can be fixedly installed with mounting hole 1421, mounting hole 3423, mounting hole 10 and mounting hole 12 respectively by bolts, so as to realize the fixed installation of the second vise unit 5 and the bridge plate body 141, and meet the needs of workpiece processing and production.

[0051] Furthermore, since mounting holes four, seven, and ten have the same structure as mounting hole one 1421, mounting holes five, eight, and eleven have the same structure as mounting hole two 1422, and mounting holes six, nine, and twelve have the same structure as mounting hole three 1423, the second vise unit 5 can also be placed in the second mounting hole group 143 and the third mounting hole group 144 for installation, realizing multi-directional fixed installation of the second vise unit 5 and meeting the needs of workpiece production and processing.
