[0030] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0031] An embodiment of the present application discloses a centering fixture for a gear grinding machine.

[0032] Reference Figure 1-3 A centering fixture for a gear grinding machine includes a base plate 1, a mounting hole 2 provided on the base plate 1 for auxiliary mounting, two first cylinders 3 symmetrically fixedly mounted on the top outer wall of the base plate 1, a mounting frame 4 fixedly mounted to the output ends of the two first cylinders 3, and a centering mechanism, a collecting mechanism, and a mounting mechanism provided on the mounting frame 4;

[0033] The centering mechanism includes two second cylinders 6 fixedly mounted on the mounting frame 4, and the output ends of the two second cylinders 6 are fixedly mounted with sliding plates 7, two connecting frames 8 fixedly mounted on the two sliding plates 7, two mounting boxes 9 fixedly mounted on the two connecting frames 8, two clamping blocks 10 detachably mounted on the two mounting boxes 9, two limiting grooves 11 provided on the top outer wall of the mounting frame 4, and two limiting blocks 12 slidably mounted in the two limiting grooves 11, and the two limiting blocks 12 are fixedly connected to the corresponding sliding plates 7;

[0034] When in use, by starting the two second cylinders 6, the output ends of the two second cylinders 6 will drive the corresponding two sliding plates 7 and two connecting frames 8 to approach each other. The two connecting frames 8 approaching each other will drive the two clamping blocks 10 to approach each other, thereby playing a role of centering clamping.

[0035] Reference Figure 2-4 The mounting mechanism includes a driving block 21 slidably mounted in the mounting box 9, two rotating plates 22 rotatably mounted on the outer wall of one side of the driving block 21, two elongated plates 25 rotatably mounted on the outer wall of one side of the two rotating plates 22, two positioning blocks 26 fixedly mounted on the outer wall of one side of the two elongated plates 25, a mounting block 20 fixedly mounted on the outer wall of one side of the clamping block 10, a mounting groove 19 provided on the outer wall of one side of the mounting box 9, and the mounting block 20 is slidably mounted in the mounting groove 19, a fixing frame 17 fixedly mounted on the mounting box 9, a third cylinder 18 fixedly mounted on the fixing frame 17, and the output end of the third cylinder 18 passes through the mounting box 9 and is fixedly connected to the driving block 21, A fixed plate 29 fixedly installed in the installation box 9, two elongated grooves 30 symmetrically opened on the bottom outer wall of the fixed plate 29, and the two elongated plates 25 are respectively slidably installed in the corresponding elongated grooves 30, the two rotating plates 22 are penetrated and rotatably installed with the first limiting columns 23, and the two first limiting columns 23 are both fixedly installed in the installation box 9, the two elongated plates 25 are penetrated and slidably installed with the second limiting columns 24, and the two second limiting columns 24 are both fixedly installed in the installation box 9, two card slots 27 opened on the outer walls on both sides of the installation block 20, two card blocks 28 slidably installed in the two card slots 27, and the two card blocks 28 are fixedly connected to the corresponding positioning blocks 26.

[0036] During use, the third cylinder 18 is started by control, and the output end of the third cylinder 18 will drive the driving block 21 to move. The driving block 21 moves and drives the two rotating plates 22 to rotate, and drives the two long plates 25 and the two positioning blocks 26 to move away from each other. The two positioning blocks 26 move away from each other, and then the fixed installation of the mounting block 20 and the clamping block 10 can be released. Therefore, the corresponding clamping block 10 can be quickly replaced according to needs, thereby improving convenience and work efficiency during use.

[0037] Reference Figure 2-5 The collecting mechanism includes a discharge port 13 provided on the mounting frame 4, a collecting box 14 fixed to the bottom outer wall of the mounting frame 4 by bolts, a push plate 5 slidably mounted in the collecting box 14, two sliding rods 15 symmetrically fixedly mounted on the outer wall of one side of the push plate 5, and one side of the two sliding rods 15 passes through the outer wall of one side of the collecting box 14 and is fixedly mounted with the same connecting rod 16, and a box door 31 hinged to the outer wall of one side of the collecting box 14;

[0038] During use, the discharge port 13 is provided so that the metal chips generated during processing can be discharged and dropped into the collection box 14, where they are collected and stored. When the metal chips in the collection box 14 need to be discharged, the box door 31 is first opened, and then the connecting rod 16 is pushed to move. The movement of the connecting rod 16 drives the two sliding rods 15 and the push plate 5 to move. The push plate 5 moves and discharges the metal chips in the collection box 14, thereby improving the working environment and reducing labor costs.

[0039] The implementation principle of the centering fixture for a gear grinding machine according to the embodiment of the present application is as follows: when in use, by controlling the two first cylinders 3, the output ends of the two first cylinders 3 will push the mounting frame 4 to move upward, so that the corresponding working height can be adjusted according to the height of the staff, thereby improving the flexibility during use; by starting the two second cylinders 6, the output ends of the two second cylinders 6 will drive the corresponding two sliding plates 7 and two connecting frames 8 to move closer to each other, and the two connecting frames 8 moving closer to each other will drive the two clamping blocks 10 to move closer to each other, thereby achieving the effect of centering and clamping;

[0040] When the clamping block 10 needs to be replaced, the third cylinder 18 is controlled to start, and the output end of the third cylinder 18 drives the driving block 21 to move. The driving block 21 moves and drives the two rotating plates 22 to rotate, and drives the two long plates 25 and the two positioning blocks 26 to move away from each other. The two positioning blocks 26 move away from each other, and then the fixed installation of the mounting block 20 and the clamping block 10 can be released. Therefore, the clamping block 10 that is suitable can be quickly replaced according to needs, thereby improving convenience and work efficiency during use;

[0041] The discharge port 13 allows the metal chips generated during processing to be discharged and fall into the collection box 14, where they are collected and stored. When the metal chips in the collection box 14 need to be discharged, the box door 31 is first opened, and then the connecting rod 16 is pushed to move. The movement of the connecting rod 16 drives the two sliding rods 15 and the push plate 5 to move. The push plate 5 moves and discharges the metal chips in the collection box 14, thereby improving the working environment and reducing labor costs.

[0042] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
