Description

Technical Field

[0001] The utility model relates to the technical field of bearing bush processing, in particular to a milling machine tool for bearing bush processing. Background Art

[0002] The bearing is the part where the sliding bearing and the journal contact. It is a semi-cylindrical surface in the shape of a tile, very smooth, and generally made of wear-resistant materials such as bronze and anti-friction alloys. There are two types of bearings: integral and split. The integral bearing is usually called a sleeve. The split bearing is divided into two identical upper and lower bearing structures relative to the semicircular structure that cuts the center of the sleeve in half;

[0003] Referring to the patent document with application number "CN201620887158.X" and titled "Tooling fixture for chamfered bearing shells", the semicircular structure of the tooling fixture not only matches the circular sleeve, but also can grasp the clamping column through the chuck of the milling machine, so that the milling machine can horizontally process the chamfered bearing shells to avoid bumping into the fixture body. However, this tooling fixture can only clamp bearing shells of one size and cannot clamp bearing shells of different sizes, and its scope of application is too small.

[0004] Therefore, we designed a milling machine tool for bearing processing. Utility Model Content

[0010] Two first sliding blocks, the two first sliding blocks slide in the installation groove, and the first sliding blocks are threadedly connected to the first bidirectional screw rod, and the two first sliding blocks are respectively fixedly connected to the two clamping plates.

[0011] Preferably, a connecting block is rotatably connected to the side wall of the mounting seat, the connecting block is fixedly connected to the first bidirectional screw rod, and a handle is slidably inserted into the connecting block.

[0012] Preferably, one of the clamping plates is provided with a connecting groove, in which a second bidirectional screw is rotatably connected, in which two second sliders are slidably connected, and the second sliders are threadedly connected to the second bidirectional screw.

[0017] The beneficial effects of the utility model are:

[0018] The utility model adopts a limiting mechanism to limit the bearing body to avoid the bearing body being biased by force when processing the bearing body. The two sides of the bearing body are clamped and fixed by the clamping mechanism. The clamping mechanism and the limiting mechanism cooperate with each other to clamp and fix the bearing body on the mounting seat, so that the operator can process the bearing body. The clamping mechanism and the limiting mechanism can be adjusted according to the size of the bearing body, so that the clamping mechanism can clamp and fix bearing bodies of different sizes, and the application range is wider.

DETAILED DESCRIPTION

[0024] Reference Figure 1-Figure 4 A bearing shell processing milling machine tool comprises a mounting seat 1 and a bearing shell body 4 placed above the mounting seat 1. The mounting seat 1 is provided with a mounting groove, and a clamping mechanism is provided in the mounting groove. The clamping mechanism comprises two clamping plates 3 for clamping and fixing the bearing shell body 4. Two limiting mechanisms are provided between the two clamping plates 3. The limiting mechanism comprises a limiting rod 8 for limiting the bearing shell body 4.

[0025] Reference Figure 2 As shown, the clamping mechanism also includes a first bidirectional screw rod 10, which is rotatably connected in the mounting groove; the clamping mechanism also includes two first sliders 2, which slide in the mounting groove, and the first sliders 2 are threadedly connected to the first bidirectional screw rod 10, and the two first sliders 2 are respectively fixedly connected to the two clamping plates 3, and a connecting block 5 is rotatably connected to the side wall of the mounting seat 1, and the connecting block 5 is fixedly connected to the first bidirectional screw rod 10, and a handle 6 is slidably inserted on the connecting block 5.

[0026] When in use, the operator manually rotates the handle 6 to drive the first bidirectional screw 10 to rotate. The rotating first bidirectional screw 10 drives the two first sliders 2 to move toward each other, and then drives the clamping plates 3 fixed on the first sliders 2 to move toward each other. The two clamping plates 3 are close to each other to clamp and fix the bearing body 4. The clamping mechanism can be adjusted according to the size of the bearing body 4, so as to achieve the purpose of clamping and fixing bearing bodies 4 of different sizes, and has a wider range of applications.

[0027] Reference Figure 3 and Figure 4 As shown, a connecting groove is opened on one of the clamping plates 3, in which a second bidirectional screw rod 11 is rotatably connected, and two second sliders 12 are slidably connected in the connecting groove, and the second sliders 12 are threadedly connected to the second bidirectional screw rod 11; a knob 7 is rotatably connected to the side wall of the clamping plate 3, and the knob 7 is coaxially fixed to the second bidirectional screw rod 11.

[0028] During use, the operator manually turns the knob 7 to drive the second bidirectional screw 11 to rotate. The rotating second bidirectional screw 11 drives the two second sliders 12 to move toward each other, and then drives the limiting mechanism to move toward each other. The distance between the two limiting mechanisms is controlled according to the size of the bearing body 4, so that the limiting rod 8 limits the bearing body 4. The limiting mechanism can be adjusted according to the size of the bearing body 4, so that the limiting mechanism can limit bearing bodies 4 of different sizes, and has a wider range of applications.

[0029] The limiting mechanism further includes two connecting rods 9, which are slidably connected to the limiting rod 8 through a spring 14, one of which is fixedly connected to the second slider 12, and the other connecting rod 9 is slidably connected to the clamping plate 3; the limiting mechanism further includes two limiting plates 13, which slide in the limiting rod 8, and the limiting plates 13 are fixedly connected to the connecting rod 9;

[0030] When the two clamping plates 3 in the clamping mechanism move toward each other, the clamping plates 3 will drive the connecting rod 9 to move, thereby stretching or compressing the spring 14. Regardless of whether the spring 14 is stretched or compressed, the limiting rod 8 is always in the center position to limit the bearing body 4.

[0031] The working principle of the utility model is as follows:

[0032] Manually rotating the knob 7 drives the second bidirectional screw 11 to rotate, and the rotating second bidirectional screw 11 drives the two second sliders 12 to move toward each other, thereby driving the limiting mechanism to move toward each other, and controlling the distance between the two limiting mechanisms according to the size of the bearing body 4, so that the limiting rod 8 limits the bearing body 4;

[0033] The manually rotating handle 6 drives the first bidirectional screw 10 to rotate, and the rotating first bidirectional screw 10 drives the two first sliders 2 to move toward each other, thereby driving the clamping plates 3 fixed on the first sliders 2 to move toward each other, and the two clamping plates 3 approach each other to clamp and fix the bearing body 4. At the same time, the clamping plates 3 drive the connecting rod 9 to move the tension spring 14, so that the limit rod 8 is always in the center position to limit the bearing body 4.

[0034] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
