[0028] The above solution is adopted: by setting the slide rod 8 and the slide sleeve 9, when the movable splint 43 moves on the top of the placement plate 2, the slide rod 8 and the slide sleeve 9 can control the moving position of the movable splint 43, so that the movable splint 43 will not move randomly during movement.

[0029] refer to Figure 2 A plug-in slot 10 is provided at the top of the slide bar 8 , and the number of the plug-in slots 10 is multiple and evenly provided at the top of the slide bar 8 .

[0030] The above solution is adopted: by setting the plug-in slots 10, the plug-in blocks 53 are inserted into the plug-in slots 10 at different positions, so that the movable clamping plate 43 can be positioned at different positions, so that the movable clamping plate 43 can clamp workpieces of different sizes.

[0031] refer to Figure 4 The plug-in assembly 5 includes a trapezoidal block 51, and the opposite sides of the two trapezoidal blocks 51 are fixedly connected with a U-shaped rod 52, and the opposite sides of the two trapezoidal blocks 51 are fixedly connected with a plug-in block 53 used in conjunction with the plug-in slot 10. The side of the plug-in block 53 away from the trapezoidal block 51 passes through the movable splint 43 and the sliding sleeve 9 and extends to the inner cavity of the plug-in slot 10, and the surface of the U-shaped rod 52 is provided with a spring 54.

[0032] The above scheme is adopted: by setting the plug-in assembly 5, after the plug-in block 53 is inserted into the plug-in slot 10, the pressure of the travel block 12 is exerted by the spring 54, so that the travel block 12 will drive the U-shaped rod 52 to squeeze the trapezoidal block 51, so that the trapezoidal block 51 will not drive the plug-in block 53 to leave the plug-in slot 10.

[0033] refer to Figure 4 A travel shell 11 is sleeved on the surface of the U-shaped rod 52 , and a travel block 12 is slidably connected to the inner cavity of the travel shell 11 , and the side of the travel block 12 close to the U-shaped rod 52 is fixedly connected to the U-shaped rod 52 .

[0035] refer to Figure 2 and Figure 3 The anti-deviation component 6 includes a moving block 61, a moving groove 62 for use with the moving block 61 is opened on the rear side of the movable splint 43, the moving block 61 is slidably connected to the inner cavity of the moving groove 62, a protective plate 63 is fixedly connected to the rear side of the moving block 61, and a positioning groove 64 is opened on the top of the moving block 61.

[0036] The above solution is adopted: by setting the anti-deviating component 6, after the movable clamping plate 43 clamps the workpiece, the protective plate 63 is pulled to drive the moving block 61 to move in the moving groove 62, so that the protective plate 63 can position the left and right sides of the workpiece.

[0037] refer to Figure 3The lifting and positioning assembly 7 includes a control electric cylinder 71, and the front and rear sides of the bottom of the control electric cylinder 71 are fixedly connected to connecting plates 72. The bottom of the connecting plate 72 is fixedly connected to the movable clamping plate 43. The output end of the control electric cylinder 71 is fixedly connected to a fixing plate 73, and the bottom of the fixing plate 73 is fixedly connected to a lifting plate 74. A positioning rod 75 used in conjunction with the positioning groove 64 is provided at the bottom of the lifting plate 74, and the number of the positioning rods 75 is multiple. A matching groove 76 is provided at the top of the lifting plate 74. The bottom of the positioning rod 75 passes through the movable clamping plate 43 and extends to the inner cavity of the positioning groove 64. The matching groove 76 is chamfered on one side close to the trapezoidal block 51 for extruding the trapezoidal block 51.

[0038] The above scheme is adopted: by setting the lifting and positioning component 7, when it is necessary to control the plug-in block 53 and the positioning rod 75 at the same time, the output end of the electric cylinder 71 is controlled to rise, which will drive the fixed plate 73 to rise, and the fixed plate 73 will drive the positioning rod 75 to move. At this time, the chamfered surface on the matching groove 76 will squeeze the trapezoidal block 51, and the trapezoidal blocks 51 will be squeezed away from each other.

[0039] The working principle of this utility model:

[0040] When in use, place the metal part to be processed on the top of the placement plate 2, then push the metal part to contact the fixed clamping plate 41, and then control the electric cylinder 71 through the PLC controller 45. The rise of the output end of the electric cylinder 71 will drive the fixed plate 73 to rise, and the rise of the fixed plate 73 will drive the lifting plate 74 to rise. At this time, the chamfered slope on the matching groove 76 will squeeze the trapezoidal block 51, and the trapezoidal blocks 51 will be squeezed away from each other. The movement of the trapezoidal block 51 will drive the U-shaped rod 52 to move in the stroke shell 11. At this time, the U-shaped rod 52 will drive the stroke block 12 to move the squeezing spring 54. After the trapezoidal block 51 drives the plug-in block 53 to disengage from the plug-in slot 10, it pushes the movable clamping plate 43 to move on the top of the placement plate 2. The movement of the movable clamping plate 43 will drive the sliding sleeve 9 to move on the surface of the sliding rod 8. When the movable splint 43 moves and contacts the metal part, the protective plate 63 is pulled to drive the movable block 61 to move in the movable groove 62. When the protective plate 63 contacts the metal part, the electric cylinder 71 is controlled by the PLC controller 45. The output end of the electric cylinder 71 is controlled to descend, which will drive the lifting plate 74 and the fixed plate 73 back to their original positions. At this time, the fixed plate 73 will drive the positioning rod 75 to be inserted into the positioning groove 64 at the top of the movable block 61, so as to fix the position of the movable block 61. After the lifting plate 74 is no longer in contact with the trapezoidal block 51, the spring 54 will undergo elastic deformation and drive the U-shaped rod 52 back to its original position. At this time, the U-shaped rod 52 will drive the plug-in block 53 fixed on the trapezoidal block 51 to be inserted into the plug-in groove 10 at the appropriate position, so as to fix the position of the movable splint 43.

[0041] To sum up: the gantry machine tool with a protective mechanism, by setting the clamping component 4, the plug-in component 5, the anti-deviation component 6 and the lifting and positioning component 7 for coordinated use, pushes the movable clamp 43 to move on the top of the placement plate 2, and the movement of the movable clamp 43 will drive the sliding sleeve 9 to move on the surface of the sliding rod 8. When the movable clamp 43 moves and contacts the metal part, it solves the problem that the clamp is often difficult to adjust to match the workpiece within a similar size range, resulting in a smaller scope of application of the clamp, so that when the clamped workpiece is too long or too short, it cannot be clamped.
