Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0030] like Figures 1-10 As shown, an engine gear chamber assembly tool comprises an assembly table 1, the upper surface of which is provided with a fixing component 2 for fixing a gear shaft;

[0031] A top plate 4 is fixedly mounted on the upper surface of the assembly table 1 through a stand 3, an electric guide rail 5 is provided on the lower surface of the top plate 4, a bracket 6 is fixedly mounted on the movable end of the electric guide rail 5, a cylinder 7 is fixedly mounted on the bottom inner side of the bracket 6, and the output end of the cylinder 7 passes through the bracket 6 and is provided with a tightening component 8 for tightening the inner wall of the gear.

[0032] The fixing assembly 2 includes two electric push rods 201 , the output ends of the two electric push rods 201 are arranged opposite to each other, and an arc-shaped clamping plate 202 is fixedly installed on the output ends of the two electric push rods 201 .

[0033] The tightening assembly 8 includes a support column 801, which is fixedly mounted on the output end of the electric push rod 201. A cavity 802 is provided in the support column 801. A rotating rod 803 is rotatably mounted between the inner walls of the cavity 802. The shaft of the rotating rod 803 is sleeved with a pushing frame 804.

[0034] A plurality of slide bars 805 are slidably provided on the inner wall of the cavity 802. A support plate 806 is fixedly installed on one end of adjacent slide bars 805. A movable plate 807 is movably provided on both sides of each support plate 806. An arc-shaped top plate 808 is fixedly installed on one side of adjacent movable plates 807.

[0035] The other ends of the adjacent slide bars 805 are fixedly mounted with a push plate 809;

[0036] The shaft of the rotating rod 803 is sleeved with a first gear 810 , and a motor 811 is fixedly installed on the bottom of the cavity 802 . The output shaft of the motor 811 is sleeved with a second gear 812 , and the second gear 812 is meshed with the first gear 810 .

[0037] The staff places the gear shaft on the assembly table 1, and then controls the electric push rod 201 so that its output end drives the arc-shaped clamping plate 202 to move, so that the arc-shaped clamping plate 202 can clamp the gear chamber. Then the staff controls the electric guide rail 5 and the cylinder 7 to move the support column 801 and the arc-shaped top plate 808 to the center hole of the gear. Then the staff starts the motor 811 so that its output shaft drives the second gear 812 to rotate. The rotating second gear 812 engages with the first gear 810, and the rotating rod 803 drives the push frame 804 to rotate. Under the push of the raised part of the push frame 804, the sliding rod 805 drives the arc-shaped top plate 808 to move, so that the arc-shaped top plate 808 can be tightened against the inside of the gear center hole, so that the gear is fixed in position during transportation and assembly, and there is no need to clamp from the outside of the gear to avoid pinching the teeth and preventing the gear quality from being affected.

[0038] In another embodiment of the present invention, a support frame 9 is fixedly installed on one side of each push plate 809 close to the push frame 804, and a roller 10 is rotatably installed between the two sides of the inner wall of each support frame 9.

[0039] By providing the roller 10 , the sliding friction generated when the pushing frame 804 rotates and pushes the push plate 809 is converted into rolling friction, thereby reducing the wear of the pushing frame 804 and the push plate 809 and extending their service life.

[0040] In another embodiment of the present invention, a first spring 11 is sleeved on a side of each sliding rod 805 close to the corresponding push plate 809 .

[0041] By setting the first spring 11, after the push frame 804 is reset, the elastic force generated by the reset of the first spring 11 drives the push plate 809 and the arc-shaped top plate 808 to reset, and the staff does not need to reset them manually, thereby reducing the workload of the staff.

[0042] In another embodiment of the present invention, a slide groove 12 is provided on both sides of each support plate 806, a slider 13 is slidably provided in each slide groove 12, and one side of each slider 13 is fixedly connected to the corresponding movable plate 807;

[0043] A round rod 14 is fixedly installed between the two sides of the inner wall of each sliding groove 12, a second spring 15 is sleeved on one side of the rod body of each round rod 14, and each slider 13 is sleeved on one side of the rod body of the corresponding round rod 14.

[0044] By providing the second spring 15, when the arc-shaped top plate 808 presses against the inner wall of the gear center hole, the second spring 15 is compressed, so that the arc-shaped top plate 808 can fit more closely against the inner wall of the gear center hole, thereby enhancing the pressing effect.

[0045] The working principle of this engine gear chamber assembly tool:

[0046] During use, the staff places the gear shaft on the assembly table 1, and then controls the electric push rod 201 so that its output end drives the arc-shaped clamping plate 202 to move, so that the arc-shaped clamping plate 202 can clamp the gear chamber. Then the staff controls the electric guide rail 5 and the cylinder 7 to move the support column 801 and the arc-shaped top plate 808 to the center hole of the gear. Then the staff starts the motor 811 so that its output shaft drives the second gear 812 to rotate. The rotating second gear 812 engages with the first gear 810, and the rotating rod 803 drives the pushing frame 804 to rotate. Under the push of the raised part of the pushing frame 804, the sliding rod 805 drives the arc-shaped top plate 808 to move, so that the arc-shaped top plate 808 can be tightened against the inside of the gear center hole, so that the gear is fixed in position during transportation and assembly, and there is no need to clamp from the outside of the gear to avoid pinching the teeth and preventing the gear quality from being affected.

[0047] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
