[0002] Cylindrical grinding machines are used to process the outer surfaces of cylindrical, conical or other shaped workpieces and the shoulder end faces. They are the most widely used and can process various cylindrical, conical outer surfaces and shoulder end faces.

[0003] Currently, when using a cylindrical grinder to process a workpiece, there may be a mismatch between the workpiece axis and the fixture axis, resulting in a deviation between the workpiece clamped by the fixture and the grinding head, causing the workpiece to tilt after grinding and not meet actual needs. Utility Model Content

[0004] In view of the defects in the prior art, the utility model provides an axis compensation fixture for an external cylindrical grinder to solve the problem that the axis and cross section of the workpiece may have deviations, so that the workpiece after grinding does not meet the actual needs.

[0005] The utility model provides an axis compensation fixture for an external cylindrical grinder, comprising:

[0006] A flange seat, one end of which is connected to the cylindrical grinder, and a first positioning hole is formed on the side wall of the other end of the flange seat;

[0007] A clamping plate, the clamping plate comprises an integrally formed matching portion and a clamping portion, the end surface of the matching portion is provided with a matching groove, the other end of the flange seat is arranged in the matching groove, the side wall of the matching portion is provided with a second positioning hole, the first positioning hole and the second positioning hole are matched and provided with a positioning pin, and the clamping portion is used to clamp a workpiece;

[0008] The steel ball is arranged in the matching groove and is located between the flange seat and the clamping plate.

[0009] It can be seen from the above technical scheme that the utility model provides an axis compensation fixture for an external cylindrical grinder, in which the flange seat and the clamping plate are connected by steel balls, and a certain angle adjustment can be achieved, so that the axis of the workpiece can coincide with the rotation axis of the fixture to achieve axis compensation.

[0010] Optionally, a first spherical groove is formed on the bottom surface of the matching groove, a second spherical groove is formed on the other end surface of the flange seat, and the steel ball is located between the first spherical groove and the second spherical groove.

[0011] Optionally, there is a gap between the inner wall of the mating groove and the outer wall of the clamping portion, there is a gap between the end face of the mating groove and the end face of the clamping portion, and there is a gap between the surface of the mating groove and the end face of the clamping portion.

[0012] It can be seen from the above technical solution that based on the above multiple gaps, a certain angle deviation can be generated between the clamping plate and the flange seat to adapt to the grinding requirements of the workpiece. By adjusting the specific dimensions of each gap, the deflection angle formed by the flange seat and the clamping plate can be adjusted to adapt to different working conditions.

[0013] Optionally, a rubber ring is further provided on the outer wall of the matching portion, and the outer diameter of the rubber ring is larger than the inner diameter of the matching groove.

[0014] It can be seen from the above technical solution that by setting a rubber ring and the outer diameter of the rubber ring is larger than the inner diameter of the matching groove, on the one hand, it can effectively reduce the workpiece powder from entering the interior of the fixture, thereby affecting the problem of the deflection angle between the flange and the clamping plate; on the other hand, it can adapt to the gap between the inner wall of the matching groove and the outer wall of the clamping part, avoiding mutual interference between the flange seat and the clamping plate.

[0015] Optionally, the end surface of the clamping portion is also provided with a rubber gasket and a wear-resistant gasket in sequence from the inside to the outside.

[0029] like Figure 1-3As shown, the present embodiment provides an axis compensation fixture for an external cylindrical grinder, comprising a flange seat 1, a clamping plate 2 and a steel ball 3. One end of the flange seat 1 is connected to the external cylindrical grinder, and a first positioning hole 11 is provided on the side wall of the other end of the flange seat 1; the clamping plate 2 comprises an integrally formed mating portion 21 and a clamping portion 22, a mating groove 211 is provided on the end surface of the mating portion 21, the other end of the flange seat 1 is arranged in the mating groove 211, a second positioning hole 212 is provided on the side wall of the mating portion 21, the first positioning hole 11 and the second positioning hole 212 are matingly provided and a positioning pin is provided through them, and the clamping portion 22 is used to clamp the workpiece 7; the steel ball 3 is arranged in the mating groove 211, and is located between the flange seat 1 and the clamping plate 2.

[0030] The cylindrical grinder axis compensation fixture provided in this embodiment is connected between the flange seat 1 and the clamping plate 2 by the steel ball 3, which can achieve a certain swing angle adjustment. When in use, the axis of the workpiece 7 can be coincident with the rotation axis of the fixture by adjusting the positioning pin, so as to avoid the problem of tilting of the workpiece 7 after grinding. At the same time, the end where the flange seat is connected to the cylindrical grinder can be specifically adjusted according to the bearing position and the connection method.

[0031] Optionally, the cylindrical grinder axis compensation fixture provided in this embodiment is made of 45# steel as a whole, which has strong wear resistance and is not easy to deform.

[0032] like Figure 3 As shown, a first spherical groove 211 a is formed on the bottom surface of the matching groove 211 , a second spherical groove 12 is formed on the other end surface of the flange seat 1 , and the steel ball 3 is located between the first spherical groove 211 a and the second spherical groove 221 .

[0033] Optionally, the surfaces of the first spherical groove 211a and the second spherical groove 12 are annealed to have strong wear resistance, thereby ensuring product precision and preventing segregation. When used, the specific sizes of the first spherical groove 211a and the second spherical groove 12 can be adjusted according to the outer diameter of the steel ball.

[0034] Specifically, there is a gap between the inner wall of the matching groove 211 and the outer wall of the clamping part 22, a gap between the end face of the matching groove 211 and the end face of the clamping part 22, and a gap between the surface of the matching groove 211 and the end face of the clamping part 22. Based on the above various gaps, a certain angle deviation can be generated between the clamping plate 2 and the flange seat 1 to meet the grinding requirements of the workpiece 7. By adjusting the specific size of each gap, the deflection angle formed by the flange seat 1 and the clamping plate 2 can be adjusted.

[0035] See also Figure 3The outer wall of the mating portion 21 is also provided with a rubber ring 4, and the outer diameter of the rubber ring 4 is larger than the inner diameter of the mating groove 211. By providing the rubber ring 4, and the outer diameter of the rubber ring 4 is larger than the inner diameter of the mating groove 211, on the one hand, a sealing effect can be achieved, and the problem of powder of the workpiece 7 entering the interior of the fixture, thereby affecting the deflection angle between the flange seat 1 and the clamping plate 2, can be effectively reduced; on the other hand, the gap between the inner wall of the mating groove 211 and the outer wall of the clamping portion 22 can be adapted to avoid mutual interference between the flange seat 1 and the clamping plate 2.

[0036] like Figure 4 As shown, the end surface of the clamping portion 22 is also provided with a rubber gasket 5 and a wear-resistant gasket 6 in sequence from the inside to the outside. The rubber gasket 5 can form an elastic contact between the clamp and the workpiece 7, which can ensure that the clamp clamps the workpiece 7 without damaging the workpiece 7 due to excessive clamping force. The wear-resistant gasket 6 is used to balance the pressure on the rubber gasket and avoid wear of the rubber gasket 5.

[0037] Based on the external cylindrical grinder axis compensation fixture provided in this embodiment, the specific usage process is: place the workpiece 7 between the symmetrically arranged external cylindrical grinder axis compensation fixtures, and adjust the deflection angle between the flange seat 1 and the clamping plate 2 by fine-tuning the positioning pins, so that the axis of the workpiece 7 and the rotation axis of the fixture coincide with each other, thereby realizing axis compensation.
