[0026] Reference Figure 1 , Figure 2A magnetic axis linear motor mover glue pouring fixture, comprising a fixture top seat 1, a fixture cover plate 2, a fixing rod 3, a fixture base 4, a clamping block 5 and a mover assembly 6, wherein the mover assembly 6 is provided with a mover body and a motor housing 61, the mover body is sleeved on the bottom of the fixing rod 3, and the two ends of the fixing rod 3 are respectively inserted into the fixture top seat 1 and the fixture base 4 to position the mover body, which can avoid the mover body being squeezed by the colloid and then shifted during the glue pouring process; and the two ends of the fixture cover plate 2 are respectively fixedly connected to the fixture top seat 1 and the fixture base 4, while ensuring that there is a gap between the fixture cover plate 2 and the mover assembly 6 for subsequent glue injection.

[0027] The motor housing 61 is arranged outside the mover body, and the motor housing 61 is connected to the clamp cover 2 and the clamp base 4, so that a glue filling space is formed between the motor housing 61 and the clamp, and a glue filling port 611 is provided at the upper end of the motor housing 61, and the glue can be injected into the glue filling space through the glue filling port 611.

[0028] The clamping block 5 is sleeved on the outside of the motor housing 61 and the fixture cover 2, and can be fastened with screws and other fasteners to tighten the clamping block 5, so that the clamping block 5 presses against the motor housing 61, so that the connection between the motor housing 61 and the fixture cover 2 is tighter, preventing glue leakage, and also facilitating later demoulding. By adopting this fixture structure, the positioning of the mover assembly 6 is more accurate during glue pouring, and the consistency of the motor movers produced can be guaranteed, which is convenient for the later assembly of the movers; at the same time, different models of movers can be produced according to motor housings of different lengths, which is highly practical.

[0029] Reference Figure 2 In an embodiment of the utility model, the mover body includes a coil 62 and a carbon fiber tube 63. The carbon fiber tube 63 is sleeved on the outside of the fixing rod 3, and the coil 62 is sleeved on the outside of the carbon fiber tube 63, so that the colloid is wrapped around the outside of the coil after the glue is poured to form a mover slider, which is also convenient for the mover slider to fall off from the fixing rod 3 after the colloid solidifies.

[0030] Reference Figure 3 In an embodiment of the utility model, an axial hole 11 is provided in the middle of the clamp top seat 1, and one end of the fixing rod 3 is inserted into the axial hole 11 to position the upper end of the fixing rod 3. The clamp top seat 1 is provided with an upper countersunk through hole 12 for fixed connection with the clamp cover plate 2.

[0031] Specifically, a limiting ring 13 is protruding from the bottom of the clamp top seat 1, and the axial hole 11 penetrates the limiting ring 13, so that the fixing rod 3 can be positioned in the limiting ring 13. At the same time, the outer diameter of the limiting ring 13 is larger than the outer diameter of the coil 62. After the clamp top seat 1 and the clamp cover plate 2 are fixedly connected, the limiting ring 13 is clamped on the inner side of the clamp cover plate 2 to further position the fixing rod 3, so that there is a glue filling space between the movable subassembly 6 sleeved on the fixing rod 3 and the clamp cover plate 2, so that the glue wraps the coil 62 after glue filling.

[0032] Reference Figure 2 In an embodiment of the utility model, a groove 21 is provided on the inner side of the clamp cover 2, and the groove 21 is matched with the limit ring 13. After the clamp top seat 1 and the clamp cover 3 are fixedly connected, the limit ring 13 is clamped in the groove 21, and the fixing rod 3 is further limited, so that there is a glue pouring space between the clamp cover 2 and the mover assembly 6; at the same time, connecting screw holes 22 are also provided at both ends of the clamp cover 2, and the connecting screw holes 22 are matched with the upper countersunk through hole 12. A countersunk screw is passed through the upper countersunk through hole 12 and tightened in the connecting screw hole 22, so that the clamp top seat 1 and the clamp cover 2 are fixedly connected together.

[0033] Reference Figure 4 , Figure 6 In the embodiment of the utility model, a positioning groove 41 is provided in the middle of the clamp base 4, and the positioning groove 41 is coaxially arranged with the shaft hole 11, and then the bottom end of the fixing rod 3 is embedded in the positioning groove 41, and the bottom of the fixing rod 3 is positioned to ensure that the fixing rod 3 is in a vertical state, which is convenient for the later installation of the movable slider and the magnetic axis; a positioning through hole 42 is provided in the positioning groove 41, and a positioning fixing hole 31 is provided at the bottom end of the fixing rod 3, and the positioning fixing hole 31 is coaxially arranged with the shaft hole 11. The positioning through hole 42 is adapted to the positioning through hole 42, and a screw is passed through the positioning through hole 42 and tightened to be fixed in the positioning fixing hole 31, so as to further fix the fixing rod 3 to avoid the problem that the fixing rod 3 will be separated from the positioning groove 41 during the later colloid solidification process and cause the solidification failure; and countersunk through holes 43 are provided on both sides of the positioning groove 41, and the countersunk through holes 43 are adapted to the connecting screw holes 22 of the clamp cover 2, and screws are also used to fix the connection between the clamp base 4 and the clamp cover 2, so as to achieve complete limitation of the fixing rod 3.

[0034] Reference Figure 5 In an embodiment of the utility model, the width of the motor housing 61 is consistent with the width of the clamp cover 2. On the one hand, when the clamp cover 2 is connected to the motor housing 61, the positioning is more accurate to prevent the phenomenon of glue leakage caused by position offset; on the other hand, it is convenient to install and top-connect the clamping block 5.

[0035] Specifically, a receiving groove 612 is provided on the inner side of the motor housing 61, and the carbon fiber tube 63 and the coil 62 are arranged in the receiving groove 612. At the same time, the internal size of the receiving groove 612 is larger than the outer diameter of the coil 62, so that a glue filling space is formed between the outer wall of the coil 62 and the groove wall of the receiving groove 612, which is conducive to the colloid wrapping the coil 62. The glue filling space is connected to the glue filling port 611 to facilitate the injection of the colloid.

[0036] Specifically, a circular limit 613 and a screw hole 614 are provided at the bottom end of the motor housing 61. The inner diameter of the circular limit 613 is smaller than the outer diameter of the coil 62, ensuring that the coil 62 is in the accommodating groove of the motor housing 61. The screw hole 614 is adapted to the countersunk through hole 43. Screws are also used to fix the motor housing 61 and the clamp base 4 to position the motor housing 61.

[0037] Reference Figure 2 In an embodiment of the utility model, a fastening screw hole 51 is provided on the side of the clamping block 5 opposite to the clamp cover plate 2. A screw is screwed into the fastening screw hole 51, and the head of the screw abuts against the end of the clamp cover plate 2. The tightness between the clamping block 5, the clamp cover plate 2 and the motor housing 61 can be adjusted by adjusting the length of the screw. The structure is simple and the operation is convenient. In addition, fasteners can be added between the clamping block 5 and the clamp cover plate 2 for clamping.
