[0020] like Figure 1 and Figure 2 As shown,

[0021] As an optional embodiment,

[0022] A positioning and clamping device comprises a limit bar 3, a Z-axis drive assembly 6, a Y-axis drive assembly 5, an X-axis drive assembly 4 and a first base plate 1, wherein the Z-axis drive assembly 6 is connected to the limit bar 3, and the Z-axis drive assembly 6 is used to drive the limit bar 3 to move forward and backward, the Y-axis drive assembly 5 is connected to the Z-axis drive assembly 6, and the Y-axis drive assembly 5 is used to drive the Z-axis drive assembly 6 and the limit bar 3 to move up and down as a whole, the X-axis drive assembly 4 is connected to the Y-axis drive assembly 5, and the X-axis drive assembly 4 is used to drive the Y-axis drive assembly 5, the Z-axis drive assembly 6 and the limit bar 3 to move left and right as a whole, and the first base plate 1 is installed below the X-axis drive assembly 4, and a limit assembly 2 for the limit bar 3 to cooperate with the locking workpiece is installed on the first base plate 1.

[0023] Specifically, the workpiece is clamped by the cooperation of the limit bar 3 and the limit assembly 2. The limit bar 3 requires three-axis linkage, that is, the spatial position of the limit bar 3 is adjusted in the three directions of the X-axis, Y-axis and Z-axis in the coordinate system. First, the X-axis drive assembly 4 is installed on the first base plate 1, and the X-axis drive assembly 4 drives the Y-axis drive assembly 5 to translate the upper end surface of the first base plate 1 to the left and right. When the X-axis drive assembly 4 moves into place, the Z-axis drive assembly 6 is moved up and down by the Y-axis drive assembly 5 to adjust the height change. The height change is further It is described that the movement direction of its height change is perpendicular to the direction parallel to the vertical line of the upper end surface of the first base plate 1. When the Y-axis driving component 5 drives the Z-axis driving component 6 to move into place, the Z-axis driving component 6 drives the limit bar 3 to move forward and backward, pushing the limit bar 3 to abut the workpiece against the limit component 2, so as to realize the positioning of the workpiece. The spatial displacement of the limit bar 3 can also be adjusted through the three-axis linkage structure to provide a larger space for the subsequent placement of the workpiece to be clamped or the removal of the processed workpiece, and the removal of the workpiece will not be hindered because the position of the limit bar 3 cannot be moved.

[0024] The specific structural design of the "X-axis drive assembly 4" mentioned above is as follows:

The guide rail 7 is fixedly connected to the upper end surface of the first base plate 1. The third slide 61 is slidably connected to the guide rail 7. The third cylinder 62 is fixed on the first base plate 1. The piston rod of the third cylinder 62 is connected to the third slide 61. The third cylinder 62 uses the first base plate 1 as a support and its piston rod pushes the third slide 61 to move left and right on the guide rail 7 to limit the spatial change of the limit bar 3 in the X-axis.

[0026] The specific structural design of the "Y-axis drive assembly 5" mentioned above is as follows:

[0027] The Y-axis driving assembly 5 includes a second slide 52 and a second cylinder 51. The second slide 52 is an L-shaped bracket, and the L-shaped bracket is vertically slidably connected to the side of the third slide 61. The second cylinder 51 is fixedly installed on the top of the third slide 61. The second cylinder 51 is used to drive the second slide 52 to slide vertically on the side of the third slide 61. The piston rod of the second cylinder 51 passes through the third slide 61 and is connected to the second slide 52. The third slide 61 is supported by the second cylinder 51. The piston rod of the second cylinder 51 pushes the second slide 52 to slide vertically on the side of the third slide 61 to achieve the height change of the limit bar 3 along the Y-axis.

[0028] The specific structural design of the "Z-axis drive assembly 6" mentioned above is as follows:

[0029] The Z-axis driving assembly 6 includes a first slide 41 and a first cylinder 42 . The first cylinder 42 is fixedly connected to the second slide 52 , and the first slide 41 is slidably connected to the second slide 52 .

[0030] The first cylinder 42 is supported by the second slide 52. The piston rod of the first cylinder 42 pushes the limit bar 3 to move forward and backward, so that the horizontal distance between the limit bar 3 and the limit assembly 2 is adjusted.

[0031] In addition, a first groove 411 and a connecting block 421 are selectively provided between the first slide 41 and the first cylinder 42. The connecting block 421 is connected to the first groove 411 through a fastener. The first groove 411 is opened on the first slide 41. The angle of the limit strip 3 can be finely adjusted through the cooperation of the connecting block 421 and the first groove 411, so as to facilitate better clamping of the workpiece later.

[0032] In order to prevent the workpiece from deviating, first limiting grooves 101 for positioning are provided on both sides of the first base plate 1. The workpiece is subsequently placed in the first limiting grooves 101, and the limiting bar 3 is subsequently moved along the X-axis, Y-axis and Z-axis directions to change the spatial position of the limiting bar 3.
