Description

Technical Field

[0001] The utility model relates to the technical field of camshaft chamber processing, in particular to an oil seal press-fitting mechanism with a back support. Background Art

[0002] The camshaft chamber is a product widely used in modern industrial applications. Figure 1 The common camshaft chamber 100 has a shaped hole 101 on its top surface, and an oil seal matching hole 102 is provided on the end wall. During the processing, an oil seal needs to be pressed into the oil seal matching hole 102. However, the wall thickness of lightweight parts is relatively thin. The thickness of the end wall of the camshaft chamber 100 is only 4mm. When the existing single-sided oil seal pressing tool is used to press the oil seal into the oil seal matching hole 102, due to the large pressing force (about 300Kg), and the lack of back support force due to single-sided pressing, the end wall of the camshaft chamber 100 is easily deformed under pressure, which seriously affects the quality of the product. Utility Model Content

[0003] In view of the deficiencies in the prior art, the utility model provides an oil seal press-fitting mechanism with a back support to overcome the deficiencies in the prior art.

[0004] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0005] An oil seal press-fitting mechanism with a back support, comprising a base, an approach slide slidably arranged on the base through a first slide rail, a press-fitting assembly arranged at one end of the approach slide, and a back support assembly spaced apart at the other end of the approach slide; an approach cylinder is arranged on one side of the base, and an output shaft of the approach cylinder is connected to the approach slide;

[0006] The press-fitting assembly comprises a press-fitting electric cylinder and a press-fitting head driven by the press-fitting electric cylinder;

[0007] The back support assembly comprises a back support seat fixedly arranged near the other end of the sliding seat and a back support rod installed on the back support seat.

[0008] Furthermore, the press-fitting assembly also includes a press-fitting slide and a second slide rail; the press-fitting electric cylinder is fixedly installed near one end of the slide, and the output shaft of the press-fitting electric cylinder is connected to the press-fitting head, the second slide rail is fixedly set near the top surface of the slide, the press-fitting slide is slidably set near the top surface of the slide through the second slide rail, and the press-fitting head is fixedly installed on the press-fitting slide.

[0009] Preferably, the back support seat is vertically fixedly arranged on the approach slide seat.

[0010] Preferably, the back support rod is transversely mounted on the back support seat, and the head of the back support rod faces the press-fitting head.

[0011] Preferably, the head of the back support rod extends to one side of the back support seat.

[0012] Preferably, the back support rod is detachably mounted on the back support seat.

[0013] Preferably, the approach slide is arranged horizontally and tilted.

[0014] Compared with the prior art, the beneficial effects of the utility model are as follows: the oil seal press-fitting mechanism with a back support in the present case supports the end wall of the camshaft chamber from the inner wall through the back support component, so that when the oil seal is press-fitted into the oil seal fitting hole of the camshaft chamber, the end wall does not deform. The press-fitting oil seal mechanism in the present case adds a back support component on the basis of the existing single-sided press-fitting technology, so that the single-sided press-fitting becomes a double-sided press-fitting with a back support, which effectively solves the problem of deformation of the end wall of the camshaft chamber caused by single-sided press-fitting.

[0024] See also Figure 1-7 The utility model provides an oil seal pressing mechanism with a back support, comprising a base 1, an approach slide 3 slidably arranged on the base 1 through a first slide rail 2, a pressing assembly arranged at one end of the approach slide 3 and a back support assembly spaced apart at the other end of the approach slide 3; an approach cylinder 4 is arranged on one side of the base 1, and the output shaft of the approach cylinder 4 is connected to the approach slide 3, so that the approach cylinder 4 drives the approach slide 3 to perform linear reciprocating motion on the base 1.

[0025] The press-fitting assembly includes a press-fitting electric cylinder 51, a press-fitting head 52, a press-fitting slide 53 and a second slide rail 54; the press-fitting electric cylinder 51 is fixedly installed near one end of the slide 3, and the output shaft of the press-fitting electric cylinder 51 is connected to the press-fitting head 52, the second slide rail 54 is fixedly set on the top surface of the slide 3, the press-fitting slide 53 is slidably set on the top surface of the slide 3 through the second slide rail 54, and the press-fitting head 52 is fixedly installed on the press-fitting slide 53; under the drive of the press-fitting electric cylinder 51, the press-fitting slide 53 carries the press-fitting head 52 to make a linear reciprocating motion on the top surface of the slide 3.

[0026] The back support assembly includes a back support seat 61 vertically fixedly arranged near the other end of the slide seat 3 and a back support rod 62 laterally installed on the back support seat 61, the head of the back support rod 62 faces the press-fitting head 52, and the head of the back support rod 62 extends to one side of the back support seat 61.

[0027] Preferably, in this embodiment, the back support rod 62 is detachably mounted on the back support seat 61, and different types of back support rods 62 can be replaced when necessary to adapt to tighten the camshaft chamber end wall from the inside to enhance its applicability.

[0028] Preferably, in the present embodiment, the approach slide 3 is arranged to be horizontally inclined, so that in actual working conditions, the back-support rod 62 can more easily approach the inner wall of the camshaft chamber 100 .

[0029] The working process of the press-fit oil seal mechanism in this case is divided into two stages:

[0030] The first stage, the stage before the oil seal is pressed (please refer to Figures 3 to 5 );

[0031] 1. Install the oil seal into the press fitting head 52;

[0032] 2. The approach cylinder 4 extends to drive the approach slide 3, thereby driving the press-fitting assembly and the back-support assembly on the approach slide 3 to move forward. At this time, the back-support rod 62 and the press-fitting head 52 have an initial assembly spacing (the camshaft chamber 100 can be placed into or taken out of the fixture without interference under this spacing);

[0033] 3. The camshaft housing 100 is placed in the fixture and positioned on the fixture. At this time, the back support rod 62 passes through the shaped hole 101 of the camshaft housing 100;

[0034] 4. The approach cylinder 4 retracts, driving the approach slide 3, thereby driving the press-fit assembly and the back-support assembly on the approach slide 3 to return. Since the camshaft chamber 100 is positioned on the fixture and does not move, the returned back-support rod 62 presses against the end wall of the camshaft chamber 100;

[0035] The second stage is the oil seal press installation stage (please refer to Figure 6 to Figure 7 );

[0036] 5. The press-fitting electric cylinder 51 extends to drive the press-fitting head 52 to push forward, and the press-fitting head 52 presses the oil seal into the oil seal fitting hole 102 of the camshaft chamber 100;

[0037] 6. The press-fitting electric cylinder 51 retreats, driving the press-fitting head 52 to retreat and reset, so that the press-fitting head 52 is separated from the camshaft chamber 100;

[0038] 7. The approach cylinder 4 extends again, driving the approach slide 3, thereby driving the press-fit assembly and the back-support assembly on the approach slide 3 forward, so that the back-support rod 62 also leaves the camshaft chamber 100;

[0039] 8. Take out the camshaft chamber 100 with the oil seal pressed in from the fixture, and the pressing process is completed.

[0040] Compared with the prior art, the oil seal pressing mechanism with a back support in this case adds a back support component on the basis of the existing single-sided pressing technology, so that the single-sided pressing becomes a double-sided pressing with a back support, which effectively solves the problem of deformation of the end wall of the camshaft chamber caused by single-sided pressing.

[0041] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model.
