Description
Technical Field
The utility model relates to a relevant technical field of gear, concretely relates to guarantee pressure equipment anchor clamps that bush oilhole and gear oilhole align.
Background
In the engine timing gear produced by our company, the oil path needs to reach the inner hole of the bushing from the tooth surface, so that the oil hole on the bushing needs to be communicated with the oil hole on the inner hole of the gear without shielding when the bushing is pressed, a former worker uses a common pressing guide post and presses the oil hole after watching the position of the oil hole with eyes, the situation that the oil hole of the gear is shielded by the bushing is frequently generated on site, the worker often reworks, the gear or the bushing is scrapped due to the reworking, the processing efficiency is seriously influenced, and the rejection rate is high.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome the not enough problem of above-mentioned, a guarantee pressure equipment anchor clamps that bush oilhole and gear oilhole align is provided.
The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: guarantee pressure equipment anchor clamps that bush oilhole and gear oilhole align, last pressure head assembly, the base assembly that corresponds from top to bottom is including, install the gear on the base assembly, it is equipped with the bush to go up pressure head assembly lower part cover, it has seted up the location shaft hole to go up the position that pressure head assembly lower part is located the suit bush, location shaft hole one end has been inserted the location axle, the fluting butt holding screw is installed to the location shaft hole other end, install the spring between location axle and the fluting butt holding screw.
The gear inner hole is sleeved on a shaft of the base assembly, the base assembly is provided with a cylindrical pin, and the cylindrical pin is inserted into a tooth groove corresponding to the gear oil hole of the gear.
The outer diameter of the end part of the positioning shaft is smaller than the inner diameter of the oil hole of the bushing.
The utility model is characterized in that: the structure is simple, the use is convenient, the gear oil hole and the bush oil hole can be ensured to be communicated without shielding, the rework time of workers is saved, the production efficiency is improved, the rejection rate is reduced, and the economic benefit is improved.

Fig. 2 is a partially enlarged view of fig. 1.
Wherein: 1. the device comprises an upper pressure head assembly 11, a positioning shaft hole 12, a slotted flat end set screw 13, a spring 14, a positioning shaft 2, a bush 21, a bush oil hole 3, a gear 31, a gear oil hole 32, an inner hole 4, a cylindrical pin 5, a base assembly 51 and a shaft.
Detailed Description
As shown in fig. 1 and 2, the utility model relates to a press mounting fixture for ensuring alignment of a bush oil hole and a gear oil hole, which comprises an upper press head assembly 1 and a base assembly 5 which correspond up and down, wherein the base assembly 5 is provided with a gear 3, an inner hole 32 of the gear 3 is sleeved on a shaft 51 of the base assembly 5, the base assembly 5 is provided with a cylindrical pin 4, the cylindrical pin 4 is inserted in a tooth groove corresponding to the gear oil hole 31 of the gear 3, the gear 3 is positioned by the inner hole 31 of the gear 3 and the tooth groove corresponding to the gear oil hole 32 of the gear 3, so as to determine the position of the gear 3, the lower part of the upper press head assembly 1 is sleeved with a bush 2, the lower part of the upper press head assembly 1 is provided with a positioning shaft hole 11 at the position where the bush 2 is sleeved, a positioning shaft 14 is inserted at the step at one end of the positioning shaft hole 11, the other end of the positioning shaft hole 11 is provided with a slotted flat-end fastening screw 12, the positioning shaft 14 and the slotted flat end set screw 12 are connected by screw threads, a spring 13 is arranged between the positioning shaft 14 and the slotted flat end set screw 12, the outer diameter of the end part of the positioning shaft 14 is smaller than the inner diameter of the bush oil hole 21 of the bush 2, so that the positioning shaft 14 can extend into the bush oil hole 21, when the bush 2 is arranged at the lower part of the upper pressure head assembly 1, the end part of the positioning shaft 14 is pressed by the inner wall of the bush 2 to shrink in the positioning shaft hole 11, at the moment, the spring 13 is stressed and compressed, when the bush oil hole 21 of the bush 2 reaches the position of the positioning shaft 14, because the positioning shaft hole 11 is communicated with the bush oil hole 21 without obstruction, the positioning shaft 14 pops out under the action of the spring force of the spring 13 and extends into the bush oil hole 21 to be matched with the bush oil hole 21, thereby determining the position of the bush 2, then, the upper pressure head assembly 1 presses down to drive the bush 2 to be pressed into the inner hole 32 of the gear 3, so that the gear oil hole 31 and the bush oil hole 21 are ensured to correspond to each other and are communicated without shielding.
When the press fitting device is used, a worker firstly installs the gear 2 on the base assembly 5, positions the gear oil hole 31 tooth space and the inner hole 32 of the gear 3 through the cylindrical pin 4 and the base assembly 5, then installs the bushing 2 on the lower part of the upper pressure head assembly 1, positions the bushing oil hole 21 through the positioning shaft 14, then starts a machine tool to start press fitting, the gear oil hole 31 and the bushing oil hole 21 can be communicated without shielding after the press fitting, and the worker takes away the press-fitted gear 3 after the press fitting and continues to process the next gear 3.
The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be within the technical scope of the present invention, and the technical solutions and the inventive concepts of the present invention are equivalent to or changed according to the present invention, and all those skilled in the art should be covered by the scope of the present invention.
