[0013] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0014] 1. In this utility model, an annular seat is provided, and multiple limiting members are fixed in a circular array on the inner wall of the annular seat. Triangular blocks are movably arranged in a circular array between adjacent limiting members. A clamping member is installed at the end of the triangular block. At the same time, a triangular top block is set between adjacent limiting members, and a driving member is installed between adjacent legs. With the above arrangement, when it is necessary to fix the gear, the gear is placed on the placement seat, and the driving member drives the triangular top block to move upward. The upward movement of the triangular top block pushes multiple triangular blocks outward synchronously, so that the clamping member is pressed against the inner wall of the gear. The gear is fixed by internal support. The structure is simple, the operation is convenient, and the practical performance is effectively increased.

[0015] 2. In this utility model, an electric push rod extending from the triangular block is provided inside the triangular block.

Multiple laser rangefinders are installed in a circular array on the annular seat. Through the above arrangement, each laser rangefinder can accurately measure the distance between itself and the clamping member. When the distances measured by the three laser rangefinders are the same, it can be determined that the central axis of the gear and the central axis of the annular seat are on the same vertical line. Conversely, when the distances detected by the three laser rangefinders are inconsistent, fine adjustment can be made by the electric push rod to ensure that the central axis of the gear and the annular seat coincide, thereby further ensuring the accuracy of gear processing.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0023] Some embodiments of this utility model are described below with reference to the accompanying drawings. Example

[0024] Combination Figure 1-4 As shown, this embodiment provides a precision tooling for gear machining, including: a main body mechanism 100.

[0025] The main body 100 includes an annular seat 110, a plurality of legs 120 fixed in an annular array on the outer surface of the annular seat 110, a plurality of limiting members 130 fixed in an annular array on the inner wall of the annular seat 110, a placement seat 140 fixed in an annular array on the annular seat 110, three triangular blocks 150 arranged in an annular array and slidably fitted between the relative limiting members 130, an electric push rod 160 fixed in the inner cavity of the triangular block 150 and extending out of the triangular block 150, a clamping member 170 fixed at the end of the electric push rod 160, a triangular top block 180 movably fitted between adjacent limiting members 130, and a driving member 190 fixed between the relative legs 120 and extending into the triangular top block 180.

[0026] The annular seat 110 is used to install other components, the support leg 120 is used to support the annular seat 110 and ensure the stability of the annular seat 110, and the limiting member 130 is used to limit the movement of the triangular block 150 and the triangular apex block 180. It includes V-shaped plates 131 fixed in a ring array on the inner wall of the annular seat 110 and round rods 132 symmetrically fixed on the top of the V-shaped plates 131. The number of V-shaped plates 131 in the array is set to three. At this time, a slot is formed between adjacent V-shaped plates 131. The triangular block 150 is fitted into the slot and slides. At the same time, the triangular apex block 180 is also fitted into the slot. Through holes 152 are opened on both sides of the triangular block 150. The round rod 132 passes through the through holes 152 to ensure the stability of the triangular block 150 when it moves.

[0027] A groove is formed on one side of the triangular block 150. The electric push rod 160 is fixed on the inner wall of the groove, with its end extending out of the groove for mounting the clamping member 170 and driving the clamping member 170 to move. The clamping member 170 is used to press against the inner ring of the gear. The clamping member 170 includes a top plate 171 fixed to the end of the electric push rod 160, a rubber pad 172 fixed to one side of the top plate 171, and support rods 173 symmetrically fixed to both sides of the top plate 171. Sleeves 151 are fixed on both sides of the triangular block 150. The support rods 173 move through the sleeves 151 to ensure the stability of the top plate 171 when it moves. The rubber pad 172 can buffer between the top plate 171 and the inner side of the gear to reduce vibration during gear processing.

[0028] In addition, laser rangefinders 111 are mounted in a circular array on the outer surface of the ring seat 110, and a reflector 1711 is fixed at the bottom of the top plate 171. The laser rangefinders 111 and the reflector 1711 correspond to each other. With this arrangement, each laser rangefinder 111 can monitor the position of its corresponding clamping member 170 in real time. When the distances measured by the three laser rangefinders 111 are the same, it can be determined that the central axis of the gear and the central axis of the ring seat 110 are on the same vertical line. Conversely, when the distances detected by the three laser rangefinders 111 are inconsistent, fine adjustment can be made by the electric push rod 160 to ensure that the central axis of the gear and the ring seat 110 coincide, thus effectively improving the gear machining accuracy.

[0029] The triangular apex block 180 moves through the adjacent V-shaped plate 131, and the inclined surface of the triangular apex block 180 is parallel to the inclined surface of the triangular block 150. With this arrangement, when the triangular apex block 180 moves upward, it can drive multiple triangular blocks 150 to move outward synchronously, thereby providing internal support and fixing for the gear. The drive unit 190 is used to drive the triangular apex block 180 to move, including a cross plate 191 with its end fixed to the bottom of the support leg 120 and an electric telescopic rod 192 fixed in the middle of the cross plate 191 and extending into the triangular apex block 180. The cross plate 191 is used to install the electric telescopic rod 192. A circular groove is opened in the middle of the top of the triangular apex block 180. The electric telescopic rod 192 extends into the circular groove, and the top of the electric telescopic rod 192 is fixedly connected to the inner top wall of the circular groove, so that when the electric telescopic rod 192 extends outward, it can drive the triangular apex block 180 to move upward, thereby driving the triangular blocks 150 to push outward, providing internal support and fixing for the gear.

[0030] The working principle and usage process of this utility model are as follows: In use, the gear is placed on the placement seat 140, the electric telescopic rod 192 is activated, which drives the triangular top block 180 to move upward. The upward movement of the triangular top block 180 drives the triangular block 150 to move outward, so that the clamping member 170 is pressed against the inner wall of the gear. The gear is fixed by the internal support. After the fixation is completed, the three laser range sensors 111 are activated synchronously to detect the distance between the three clamping blocks and themselves. When the distances measured by the three laser range sensors 111 are the same, it can be determined that the central axis of the gear and the central axis of the ring seat 110 are on the same vertical line. Conversely, when the distances detected by the three laser range sensors 111 are inconsistent, fine adjustment can be made by the electric push rod 160 to ensure that the central axis of the gear and the ring seat 110 coincide.

[0031] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
