The present application is described in further detail below with reference to figures 1-3.
The embodiment of the application discloses a grinding machine clamping device.
Referring to fig. 1, a clamping device for a grinding machine includes a clamping base 1 and a clamping drive 2.
Referring to fig. 1 and 3, a mounting hole 11 is formed in the middle of the clamping base 1, the mounting hole 11 includes a clamping hole 111 and a limiting hole 112 which are coaxial, the diameter of the limiting hole 112 is smaller than that of the clamping hole 111, and a positioning circular plate 31 of the single-rod bearing 3 is coaxially inserted into the clamping hole 111 and abuts against the bottom wall of the clamping hole 111. The single-rod bearing 3 is limited along the self axial direction.
Referring to fig. 1 and 2, the clamping base 1 is coaxially and integrally formed with a guiding tapered surface 12 at an end of the limiting hole 112 away from the clamping hole 111. After the clamping base body 1 clamps the single-rod bearing 3, the guide conical surface 12 of the clamping base body 1 is abutted to the tip of the grinding machine to slide, the tip can automatically slide to the positioning groove 32 at one end of the single-rod bearing 3, and then the other tip of the grinding machine is abutted to the positioning groove 32 at the other end of the single-rod bearing 3 to complete the fixed clamping of the single-rod bearing 3, so that the operation of clamping the single-rod bearing 3 is more convenient.
The clamping base 1 is integrally formed with a guiding inclined surface 13 at one end of the clamping hole 111 far away from the limiting hole 112. The single-rod bearing 3 can be conveniently coaxially positioned in the clamping hole 111, so that the installation operation of the single-rod bearing 3 on the clamping base body 1 is more convenient.
The clamping base body 1 is provided with a deformation groove 14 penetrating through the clamping hole 111 and the limiting hole 112 along the direction perpendicular to the axial line of the clamping hole 111, and the deformation groove 14 is communicated to one side end of the clamping base body 1 along the length direction of the clamping base body 1. One end, far away from the opening of the deformation groove 14, of the clamping base body 1 in the deformation groove 14 is provided with a pressure reducing hole 15 communicated with the deformation groove 14, the diameter of the pressure reducing hole 15 is larger than the width of the deformation groove 14, and the axis of the pressure reducing hole 15 is parallel to the axis of the clamping hole 111. The clamping base body 1 is integrally formed into an arc surface 16 at one side end of the pressure relief hole 15 far away from the deformation groove 14. The pressure relief hole 15 increases the stress area of the clamping base body 1 when the deformation groove 14 is narrowed, reduces the stress when the clamping base body 1 is deformed, and the cambered surface 16 further reduces the stress applied to the clamping base body 1 compared with a plane, reduces the probability of fracture of the clamping base body 1 caused by frequent deformation, and is beneficial to prolonging the service life.

The groove 19 reduces the axial length of the insertion hole 17 along the insertion hole 17, so that when the clamping base body 1 deforms and the deformation groove 14 narrows, the radial displacement of the end, far away from the deformation groove 14, of the clamping base body 1 along the insertion hole 17 is small, the probability that the clamping bolt 21 is not coaxial with the threaded hole 18 due to the fact that the inner peripheral wall of the insertion hole 17 abuts against the peripheral side end of the clamping bolt 21 is reduced, the probability of thread damage is reduced, and the service life of the clamping bolt 21 and the service life of the threaded hole 18 are prolonged.
A wrench 22 for driving the clamping bolt 21 to rotate is coaxially welded to the head 211 of the clamping bolt 21. The wrench 22 does not need to be aligned with the screw head 211 of the clamping bolt 21 and then screwed again, so that the operation of turning the clamping bolt 21 is more convenient.
The material of the head 211 of the clamping bolt 21 is copper. The texture of copper is softer and more plastic than steel, reducing the probability of wear of the clamping base 1 and the clamping bolt 21 caused by vibration when the grinding machine is used for machining an excircle.
