Technical Field

[0001] The utility model relates to the technical field of linear motors, and more particularly, to a linear motor facilitating positioning. Background Art

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. During the assembly process of a linear motor, the stator and the base plate are often connected by bolts. However, since a large number of stators are required for installation, when each stator needs to be individually installed with bolts, not only does the overall installation efficiency slow down, but also displacement occurs during the installation of the stator, resulting in a low straightness between stators, which reduces the performance of the linear motor. Therefore, we propose a linear motor facilitating positioning to solve the above problems. Summary of the Utility Model

The placement rack 701 is snap-fitted inside the guiding groove 5. A plurality of placement grooves 702 are provided on the upper surface of the placement rack 701. A plurality of stators 6 are respectively installed inside the placement grooves 702. An engaging rack 703 is snap-fitted at the upper end of the placement rack 701, and the two ends of the upper surface inside the engaging rack 703 are in contact with the two ends of the upper surface of the stator 6.

[0021] As Figure 4As shown, in another embodiment of the present utility model, first grooves 706 are respectively provided at both ends inside the placement rack 701. Positioning racks 705 are respectively and movably installed through both ends inside the first grooves 706. First positioning holes 704 are respectively provided through the front and rear ends of the engaging rack 703. The mutually remote ends of the positioning racks 705 are respectively engaged and installed inside the first positioning holes 704. First springs 707 are respectively provided between the mutually close ends of the positioning racks 705 and the first grooves 706. Positioning blocks 708 are respectively installed at the front and rear ends of the lower surface of the placement rack 701. Positioning grooves 709 are respectively provided at the front and rear ends of the inner lower surface of the guiding groove 5. The positioning blocks 708 are respectively engaged and installed inside the positioning grooves 709. Second grooves 712 are respectively provided at the front and rear ends inside the sliding rail 2. The second grooves 712 are parallel to the positioning grooves 709. Positioning rods 711 are respectively and movably installed through the second grooves 712. The mutually close ends of the positioning rods 711 are respectively and movably installed inside the positioning grooves 709. Second positioning holes 710 are provided through one end of the positioning blocks 708 located inside the positioning grooves 709. One end of the positioning rods 711 located inside the positioning grooves 709 is engaged and installed inside the second positioning holes 710. Clamping plates 714 are respectively installed on the outer sides of the rod bodies of the positioning rods 711 located inside the second grooves 712, and the clamping plates 714 are movably installed inside the second grooves 712.

[0022] When the user needs to position and install the stator 6, they only need to place the stator 6 into the placement slots 702 respectively to complete the installation work of the stator 6. The distance and shape between the placement slots 702 can ensure that the distance between each stator 6 is consistent, and at the same time, there will be no situation of angular or positional deviation of the stator 6. Then, the user sleeves the engaging rack 703 on the upper end of the placement rack 701, and the engaging rack 703 cooperates with the placement rack 701 to clamp and position the stator 6. The first spring 707 can then push the positioning rack 705 into the first positioning hole 704 to achieve the positioning of the engaging rack 703, so that the engaging rack 703 can stably clamp the stator 6. Then, the user moves the placement rack 701 down along the guiding groove 5 for placement, so that the placement rack 701 drives the positioning blocks 708 to be inserted into the positioning grooves 709 to accurately position the placement rack 701. After the installation of the placement rack 701 is completed, the positioning of the placement rack 701 can be achieved through the engagement between the positioning rod 711 and the second positioning hole 710 to complete the installation work of the stator 6, and it is also convenient for the user to disassemble the stator 6 later;

[0023] When it is necessary to disassemble the clamping frame 703, the user only needs to push the positioning frame 705 to make the positioning frame 705 disengage from the first positioning hole 704, and then the user can remove the clamping frame 703, which is more convenient.

[0024] The working principle of the linear motor that is convenient for positioning is as follows:

[0025] When in use, first, when the user needs to position and install the stator 6, the user only needs to place the stator 6 into the interior of the placement groove 702 respectively, and the installation work of the stator 6 can be completed. The distance and shape between the placement grooves 702 can ensure that the distance between each stator 6 is consistent, and at the same time, the situation of angle or position deviation of the stator 6 will not occur. Then the user sleeved the clamping frame 703 on the upper end of the placement frame 701, and the clamping frame 703 cooperated with the placement frame 701 to clamp and position the stator 6. The first spring 707 can push the positioning frame 705 to snap into the interior of the first positioning hole 704, realizing the positioning of the clamping frame 703, so that the clamping frame 703 can stably clamp the stator 6. Then the user moves the placement frame 701 downward along the guiding groove 5 for placement, so that the placement frame 701 drives the positioning block 708 to snap into the interior of the positioning groove 709 to accurately position the position of the placement frame 701. Then after the installation of the placement frame 701 is completed, the positioning of the placement frame 701 can be achieved through the engagement between the positioning rod 711 and the second positioning hole 710, completing the installation work of the stator 6, and it is also convenient for the user to disassemble the stator 6 later.
