For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0027] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0028] like Figure 1-5 As shown, a flattening tool for quick rotation of 90° comprises: a base 1, having an inner hole 101, the base 1 is used to be set on the tailstock of the grinding machine, the base 1 has a clamping groove 102, the clamping groove 102 has four, the four clamping grooves 102 are arranged in an array with equal angle intervals along the circumference of the base 1, the clamping groove 102 is arranged along the radial direction of the base 1, the clamping groove 102 has a through portion 1021 and a clamping portion 1022, the through portion 1021 is connected to the clamping portion 1022, and the through portion 1021 is connected to the outside of the base 1. The clamping portion 1022 is connected to the inner hole 101; a rotating chuck 2 is rotatably sleeved in the inner hole 101, the rotating chuck 2 has a clamping nozzle 201, and the clamping nozzle 201 is used to clamp the workpiece 5; an elastic clamp 3 is arranged on the rotating chuck 2, the elastic clamp 3 has a clamping member 301, and the clamping member 301 is used to clamp with the clamping portion 1022. The push rod 4 is also included. The push rod 4 is slidably disposed in the through portion 1021 , and the end of the push rod 4 is used to abut against the locking member 301 .

[0029] When in use, the base 1 is mounted on the tailstock of the grinder for fixing, and then the rotating chuck 2 uses the clamping nozzle 201 to clamp the workpiece 5, and the elastic clamp 3 can make the clamping member 301 clamped in the clamping portion 1022, and at the same time, the clamping member 301 can be separated from the clamping portion 1022 under the action of external force. After the clamping member 301 is clamped in the first clamping portion 1022, the rotating chuck 2 cannot rotate relative to the base 1, and the first flat position of the workpiece 5 is ground. After the processing of the flat position is completed, the push rod 4 can be inserted into the through hole. Part 1021, use the push rod 4 to press the clamping piece 301, so that the clamping piece 301 is disengaged from the clamping part 1022, and the push rod 4 is in the clamping groove 102. At this time, the rotating chuck 2 can rotate 90° relative to the base 1, and the clamping piece 301 is opposite to the next clamping groove 102 adjacent to the circumferential direction. Pull out the push rod 4, and the clamping piece 301 is clamped and positioned with the second clamping part 1022. After the rotating chuck 2 rotates 90°, it is fixedly clamped on the base 1. After the workpiece 5 completes the 90° rotation, the second flat position can be ground. By analogy, the four flat positions can be quickly exchanged, the operation is simple and fast, and the positioning is accurate.

[0030] The rotating chuck 2 is matched with a small clearance inside the base 1, or a bearing connection can be added, for example, the bearing is set inside the base 1, the outer side of the bearing is set on the base 1, and the inner side of the bearing is set outside the rotating chuck 2, so as to improve the coaxiality of the rotating chuck 2 and the base 1, make the rotation smoother and more labor-saving, and the grinding accuracy of the workpiece 5 is higher.

[0031] The rotary chuck 2 clamping the workpiece 5 is a prior art, which will not be described in detail herein. When the base 1 is mounted on the tailstock of the grinding machine, a corresponding adaptation structure is sufficient, and a person skilled in the art can implement it.

[0032] Further, the rotating chuck 2 has a mounting hole 202, which is arranged along the radial direction of the rotating chuck 2, and the mounting hole 202 is opposite to the clamping groove 102. The clamping member 301 is slidably arranged in the mounting hole 202, and the clamping member 301 is engaged or disengaged with the clamping portion 1022 after sliding; the elastic clamping member 3 also has: an elastic member 302, which is arranged in the mounting hole 202, one end of the elastic member 302 acts on the clamping member 301, and the other end acts on the rotating chuck 2, and is used to provide pressure for the clamping member 301 to abut against the clamping groove 102. The elastic member 302 is a compression spring.

[0033] When in use, the elastic clamp 3 can adopt the structure of a compression spring and a clamping member 301. Under the action of the push rod 4, the clamping member 301 can compress the compression spring and move in the axial direction to break away from the clamping connection with the clamping portion 1022. In the process of breaking away from the clamping portion 1022, the clamping member 301 can try to rotate the rotating chuck 2 slightly so that the worker can feel it after breaking away from the clamping connection. Of course, a clamping protrusion can be set in the mounting hole 202 to provide a limit prompt. After the clamping member 301 compresses the compression spring for a distance, it abuts on the clamping protrusion. The clamping member 301 breaks away from the clamping connection with the clamping portion 1022, and the push rod 4 does not enter the mounting hole 202.

[0034] The elastic member 302 may be a compression spring, an elastic rubber column, an elastic tube, etc. The mounting hole 202 may be a stepped hole to facilitate mounting the elastic member 302 .

[0035] Furthermore, the locking member 301 is a steel ball, and the locking portion 1022 is a truncated cone structure.

[0036] When in use, the locking member 301 is a spherical steel ball, and the locking portion 1022 is a truncated cone structure. The opening diameter of the locking portion 1022 of the truncated cone structure close to the rotating chuck 2 is larger than the other side. The steel ball can abut against the conical locking portion 1022, and when in the locking state, the locking member 301 can be half located in the locking portion 1022 and the other half located in the mounting hole 202 to achieve stable locking.

[0037] The locking member 301 can also be a cylindrical structure, a truncated cone structure or a conical structure, the locking portion 1022 can be a truncated cone structure or a cylindrical structure, the through portion 1021 can be a through hole structure, and the diameter of the locking portion 1022 is smaller than the diameter of the through portion 1021. At this time, the end of the locking member 301 can be chamfered to facilitate disengagement from the locking portion 1022.

[0038] It is understood that the present invention is described by some embodiments, and those skilled in the art are aware that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application are within the scope of protection of the present invention.
