[0044] The present utility model provides a special tool for assembling a linear bearing of a wire cutting machine. Refer to Figure 1 , which includes a base 1, on which a rotary assembly mechanism 2 and a bearing transportation mechanism 3 and a bearing pressing mechanism 4 respectively arranged on both sides of the rotary assembly mechanism 2 are provided. The rotary assembly mechanism 2 includes a rotary motor 21 and a rotary plate 22 sleeved on the driving shaft of the rotary motor 21. The rotary plate 22 rotates synchronously with the rotary motor 21. Generally speaking, the shape of the rotary plate 22 is circular and concentrically matched with the driving shaft of the rotary motor 21. A plurality of assembly grooves 23 arranged in a ring are provided on the upper surface of the rotary plate 22. Generally speaking, the plurality of assembly grooves 23 arranged in a ring are concentrically matched with the driving shaft of the rotary motor 21. A positioning post 23.1 is provided in the assembly groove 23, and a part to be assembled is suitable for being sleeved on the positioning post 23.1. The bearing transportation mechanism 3 includes a bracket 3 arranged on the base 1 and a bearing groove 32 supported by the bracket 3. A bearing 5 is suitable for being loaded in the bearing groove 32. A through groove 32.1 is provided at one end of the bearing groove 32 close to the rotary plate 22. The size of the through groove 32.1 is generally slightly larger than the bearing 5 to ensure that only one bearing can pass through the through groove 32.1 each time. During loading, the rotary motor 21 rotates the assembly groove 23 to the lower part of the through groove 32.1, and the bearing 5 falls from the through groove 32.1 and falls above the part to be assembled with the positioning post 23.1 as the axis. The bearing pressing mechanism 4 includes a truss 41 arranged on the base 1 and a pressing part 42 arranged on the truss 41. During pressing, the rotary motor 21 rotates the assembly groove 23 loaded with the part to be assembled and the bearing 5 to the lower part of the through hole, and the pressing part 42 presses the bearing downward. Through the above settings, the device realizes the automatic assembly of the linear bearing of the wire cutting machine, and the device has a simple structure, convenient operation and high assembly efficiency.

[0045] Furthermore, the number of the assembly grooves 23 is 4 to 12, and preferably, the number of the assembly grooves 23 is 6.

In this device, refer to Figure 1 , regardless of the number of the assembly grooves 23, the assembly grooves 23 form a queue in turn waiting for operation. Generally speaking, there will be several assembly grooves 23 between the operations of the bearing transportation mechanism 3 and the bearing pressing mechanism 4 to leave time and space for taking out the assembled parts in the assembly groove 23 and putting in the parts to be assembled again. In addition, the bearing transportation mechanism 3 and the bearing pressing mechanism 4 can operate on different assembly grooves 23 at the same time, and the assembly grooves 23 not being operated continue to wait until their positions are rotated under the bearing transportation mechanism 3 or the bearing pressing mechanism 4.

[0051] For the special tool for assembling linear bearings provided by the present utility model, the top end of the positioning post 23.1 is a tip, enabling the bearing 5 to pass through the through groove 32.1 more smoothly.

[0052] A usage method of the present utility model is provided herein. The rotating motor 21 in this device always rotates without special instructions. When the assembly groove 23 loaded with parts to be assembled rotates below the through groove 32.1 and when the assembly groove 23 loaded with parts to be assembled and the bearing 5 rotates below the pressing member 42, the rotating motor 21 stops briefly until the loading or pressing action is completed, and then the rotating motor 21 continues to rotate. The specific steps are as follows:

[0053] 1) Manually sleeved the parts to be assembled on the positioning post 23.1 in the assembly groove 23;

[0054] 2) The assembly groove 23 loaded with parts to be assembled rotates below the bearing groove 32, and the conveyor belt 32.2 in the bearing groove 32 starts to push the bearing 5 towards the direction of the through groove 32.1 until a bearing falls above the parts to be assembled with the positioning post 23.1 as the axis;

[0055] 3) The assembly groove 23 loaded with parts to be assembled and the bearing 5 rotates below the pressing member 42, and the pressing member 42 presses down the bearing to complete the assembly;

[0056] 4) The assembly groove 23 loaded with assembled parts rotates away from below the pressing member 42, and then manually take out the assembled parts and put in new parts to be assembled.

[0057] 5) Repeat the above steps until all parts to be assembled are assembled.

[0058] The above are only the preferred embodiments of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present utility model, several improvements and substitutions can be made, and these improvements and substitutions should also be regarded as the protection scope of the present utility model.
