Detailed Description

The preferred embodiments of the present utility model will be described in detail below with reference to the accompanying drawings so that the advantages and features of the present utility model can be more easily understood by those skilled in the art, thereby making clear and defining the scope of the present utility model.

Referring to fig. 1 to 4, an embodiment of the present utility model includes:

a riveter oil tube assembly jig, the oil tube assembly comprising an oil tube 1 and an oil seal 2, the riveter oil tube assembly jig comprising: the fixture frame, the oil pipe locating plate 16 and the oil seal ejection assembly mechanism; the fixture frame comprises a top plate 3, a bottom plate 5 and two side plates 4, leveling feet 6 are arranged below the bottom plate, an oil seal positioning plate 16 is fixed on the bottom plate 5, an oil seal ejection assembly mechanism is mounted by means of the

top plate

3, 4 oil seal fixing seats 17 matched with the bottom outline of the oil seal 1 are arranged on the oil

seal positioning plate

16, 4 oil seal mounting positions are arranged on the oil seal ejection assembly mechanism and correspond to the oil seal fixing seats 17 one by one, the oil seal mounting positions are located right above the pipe orifices of the oil pipe 1 after the oil pipe 1 is placed on the oil pipe fixing seats, and the oil seal ejection assembly mechanism can drive the oil seal mounting positions to vertically move to reach the pipe orifice positions of the oil pipe 1 and then jack the oil seal 2 placed in the oil seal mounting positions into the oil pipe 1.

The oil pipe support plate 14 is further installed in the clamp frame, two ends of the oil pipe support plate 14 are fixed on the side plates 4 on two sides and are integrally parallel to the

bottom plate

5, 4 oil pipe clamping ports 15 are formed in the oil pipe support plate 14, and the number of the oil pipe clamping ports 15 is the same as that of the oil pipe fixing seats 17 and is located right below the oil seal installation position. In this way, when the bottom of the oil pipe 1 is mounted on the oil pipe fixing seat 17, the neck of the oil pipe 1 is clamped by the oil pipe clamping opening 15, so that the form of the oil pipe 1 can be further stabilized, and the misalignment of the pipe orifice of the oil pipe 1 and the oil seal mounting position can be prevented. The back of the oil pipe locating plate 16 is provided with a limiting back plate 18, and the position deviation in the front-back direction when the oil pipe 1 is put in can be prevented from causing the spatial position error of the pipe orifice by using the limiting back plate 18.

The material of the oil pipe locating plate 16 and the oil pipe supporting plate 14 is generally PP or PE, because PP or PE has better strength and certain elasticity, and the hardness is lower than that of the oil pipe 1, and the surface of the oil pipe 1 is not damaged when certain clamping force can be generated to the clamping position during the interference fit loading.

The oil seal ejection assembly mechanism comprises a driving cylinder 7, a cylinder telescopic rod 8, a push plate 10, a pressing plate 11 and a limiting slide rod 9, wherein the driving cylinder 7 is arranged at the middle position of a top plate 3, the cylinder telescopic rod 8 penetrates through a through hole in the center of the top plate 3 and then is connected with the

push plate

10, 2 lifting slide rods 12 with the same specification are symmetrically arranged on the push plate 10 about the cylinder telescopic rod 8, the pressing plate 11 is lifted under the push plate 10 through the lifting slide rods 12, oil seal installation positions are uniformly distributed on the pressing plate 11, a penetrating ejector pin hole is formed in the bottom of each oil seal installation position, ejector pins 13 are arranged on the push plate 10 according to the ejector pin hole positions of the oil seal installation positions, each ejector pin 13 corresponds to one oil seal installation position, the limiting slide rods 9 are symmetrically arranged on the inner side of the bottom plate 5, and the rod body of each limiting slide rod 9 continuously penetrates through the preset limiting holes on the push plate 10 and the pressing plate 11. In this way, when the oil seal 2 is placed in the oil seal installation position, as long as the driving cylinder 7 is started, the cylinder telescopic rod 8 extends forwards, the push plate 10 and the pressing plate 12 synchronously downwards together, when the pressing plate 12 reaches the pipe orifice of the oil pipe 1, the push plate 10 continuously pushes down, the ejector pin 13 is ejected into the oil seal installation position through the ejector pin hole 13, the oil seal 2 is pressed into the oil pipe 1, and after the pressing-in action is completed, the cylinder telescopic rod 8 contracts and resets, so that the assembly action is completed.

The distance between the plane of the end of the limit sliding rod 9 and the plane of the pipe orifice of the well placed oil pipe 1 is smaller than the thickness of the pressing plate 11. Therefore, the pressing plate 11 can be prevented from being separated from the limiting slide bar after reset, and dislocation between the limiting slide bar 9 and a limiting hole on the pressing plate 11 is easily caused after long-term use, so that faults are caused.

The section shape of the oil seal installation position is matched with the outline of the oil seal 2, and is in interference fit with the oil seal 2. Because the oil seal 2 is lighter, and the outside of the oil seal 2 is provided with an elastic rubber ring structure, when the oil seal is installed, the friction between the rubber ring and the oil seal installation position can reversely suspend the oil seal 2 in the oil seal installation position through interference fit, otherwise, the oil seal 2 is easy to be separated after being installed because the opening of the oil seal installation position is downward.

The foregoing description is only illustrative of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structures or equivalent processes or direct or indirect application in other related technical fields are included in the scope of the present utility model.
