Figure 1-6 As shown, by setting the clamping assembly 10, shaft workpieces of different sizes can be clamped and stabilized. By setting the locking assembly 11, the fixing plate 1013 can be limited and locked, thereby ensuring that the vibration force generated when drilling the workpiece will not cause the extrusion plate 1015 to separate from the workpiece, thereby causing the workpiece to deviate. At the same time, the drilling accuracy of the workpiece can also be improved.

[0031] An extension rod 1105 is fixedly connected to one side surface of the sleeve 1101, and a stabilizing rod 1106 is fixedly connected to one side surface of the clamping rod 1102 away from the sleeve 1101.

Figure 4 , 5 As shown, after the limit rod 1107 is pulled to separate the limit rod 1107 from the limit slot 1110, and then the clamping rod 1102 is pulled to separate the clamping rod 1102 from the clamping slot 1018, the stabilizing plate 1011 can be pushed so that the stabilizing plate 1011 can drive the extrusion plate 1015 to move, and the shaft workpiece can be positioned and clamped through the movement of the extrusion plate 1015. At the same time, the third spring 1104 and the fourth spring 1108 are rubber composite springs in the prior art. The elastic force of the rubber composite spring is relatively large, so that the vibration generated during drilling will not separate the clamping rod 1102, the limit rod 1107 from the clamping slot 1018 and the limit slot 1110, thereby ensuring the stable clamping of the workpiece.

[0032] The extension plate 4 has a groove 5 formed inside, a linear guide 6 is fixedly installed inside the groove 5, a sleeve 7 is slidably connected to the surface of the linear guide 6, a cylinder 8 is connected through the middle of the top surface of the sleeve 7, and a drilling member 9 is fixedly connected to the bottom surface of the cylinder 8. Figure 2 As shown, the model of the linear guide rail 6 is JSA-LZG35K, and the cylinder 8 and the linear guide rail 6 are staggered and penetrate the sliding sleeve 7.

[0033] A fixing rod 1005 is fixedly connected to one side of the surface of the clamping plate 1004, a first spring 1006 is fixedly connected to one side of the fixing rod 1005, a support plate 1007 is fixedly connected to the middle of the top surface of the connecting plate 1001, a rotating block 1008 is rotatably connected to the top surface of the supporting plate 1007, a connecting rod 1009 is fixedly connected to the middle of the surface of the rotating block 1008, a push rod 1010 is fixedly connected to one side of the surface of the rotating block 1008, a stabilizing plate 1011 is penetrated and connected to the side surface of the connecting rod 1009 away from the rotating block 1008, and a side surface of the connecting rod 1009 away from the stabilizing plate 1011 A rotating disk 1012 is fixedly connected, the rotating disk 1012 is rotatably connected to the stabilizing plate 1011, the bottom surface of the stabilizing plate 1011 is fixedly connected to the connecting plate 1001, a second spring 1014 is symmetrically installed on one side surface of the fixing plate 1013, and a pressing plate 1015 is fixedly connected to the side surface of the second spring 1014 away from the fixing plate 1013, a sliding groove 1017 is provided on the top surface of the clamping plate 1004, the sliding groove 1017 is slidably connected to the sliding block 1016, and a plurality of card slots 1018 are provided inside the sliding groove 1017, and the card slot 1018 is card-engaged with the card rod 1102, such as Figure 1-3 As shown, by pushing the push rod 1010, the push rod 1010 drives the connecting rod 1009 to rotate, and the rotation of the connecting rod 1009 drives the rotating disk 1012 to rotate. By the rotation of the rotating disk 1012, the rotating disk 1012 no longer squeezes the clamping plate 1004, so that the two clamping plates 1004 move toward the middle under the action of the first spring 1006, so that the shaft workpiece can be clamped. When facing a smaller shaft workpiece, the clamping rod 1102 on the locking assembly 11 is separated from the clamping groove 1018 Afterwards, by pushing the fixed plate 1013, the fixed plate 1013 can drive the extrusion plate 1015 to move. Through the movement of the extrusion plate 1015, the shaft workpiece can be positioned and clamped. At the same time, the first spring 1006 and the second spring 1014 are also rubber composite springs in the prior art. The rubber composite spring has a large elasticity, so that the vibration generated during drilling will only cause the second spring 1014 to vibrate slightly, thereby not reducing the clamping force of the extrusion plate 1015 on the workpiece, thereby ensuring the stability and accuracy of the workpiece during drilling.

[0034] Working principle: Before using this precision shaft drilling machine with a locking component, it is necessary to check the overall condition of the device to ensure that it can work normally. Figure 1 - Figure 6As shown, firstly, by setting the locking assembly 11, by pulling the limit rod 1107, the limit rod 1107 is separated from the limit groove 1110, and by pulling the clamping rod 1102, the clamping rod 1102 is separated from the clamping groove 1018, the stabilizing plate 1011 can be pushed so that the stabilizing plate 1011 can drive the extrusion plate 1015 to move, and the movement of the extrusion plate 1015 can position and clamp the shaft workpiece, and at the same time, through the action of the second spring 1014, the second spring 1014 is squeezed, so that the second spring 1014 The extrusion plate 1015 will be squeezed, so that the extrusion plate 1015 will squeeze the shaft workpiece after being squeezed, thereby ensuring the stability of the shaft workpiece. At the same time, when the stabilizing plate 1011 moves to a suitable position, by loosening the clamping rod 1102, the clamping rod 1102 is re-engaged with the clamping slot 1018 under the action of the third spring 1104, and at the same time, by loosening the limiting rod 1107, the limiting rod 1107 is re-engaged with the limiting slot 1110 under the action of the fourth spring 1108, thereby completing the movement and limitation of the stabilizing plate 1011.

[0035] Secondly, by setting the clamping assembly 10, by pushing the push rod 1010, the push rod 1010 drives the connecting rod 1009 to rotate, and the rotation of the connecting rod 1009 drives the rotating disk 1012 to rotate. Through the rotation of the rotating disk 1012, the rotating disk 1012 no longer squeezes the clamping plate 1004, so that the two clamping plates 1004 move toward the middle under the action of the first spring 1006, so that the shaft workpiece can be clamped. When facing a smaller shaft workpiece, after separating the clamping rod 1102 on the locking assembly 11 from the clamping groove 1018, the fixed plate 1013 is pushed, so that the fixed plate 1013 can drive the extrusion plate 1015 to move. Through the movement of the extrusion plate 1015, the shaft workpiece can be positioned and clamped, so that the clamping of shaft workpieces of different sizes and models can be met, and the accuracy of drilling holes in the shaft workpiece is also ensured.
