Description

Technical Field

[0001] This utility model belongs to the field of mechanical technology and relates to a glue-dispensing fixture, particularly a glue-dispensing fixture for a linear motor actuator. Background Technology

[0002] Existing linear motors generally consist of a mover and a stator, such as... Figure 1 As shown, the moving element 8 is elongated and includes an elongated iron core 8a, copper wire wound on the iron core 8a, a rectangular ring-shaped cooling water pipe assembly 8b that is sleeved around the iron core 8a, and an electrical wire connected to the copper wire. The cooling water pipe assembly includes an inlet 8c and an outlet 8d. The bottom of the iron core 8a is provided with multiple rows of threaded holes 8e.

[0003] To improve the sealing and protection performance of the mover, a new approach is to perform epoxy potting on the mover. However, epoxy potting requires potting fixtures, and the fixtures currently on the market are not designed for linear motor stators, resulting in some degree of incompatibility and inconvenience during use. Utility Model Content

[0004] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a tooling specifically for dispensing glue to the mover of a linear motor.

[0005] The objective of this utility model can be achieved through the following technical solution: A linear motor mover potting fixture includes a rectangular box with an open top, which is formed by two long plates, two short plates, and a bottom plate. The mover is horizontally placed into the rectangular box through the open top and pressed against the bottom plate. One of the short plates is provided with two sealing holes and a wire outlet hole for the mover wire to extend out. The two sealing holes are respectively positioned opposite the water inlet and water outlet of the mover. The feature is that the short plates and long plates are detachably fixed to the bottom plate, and the two ends of the long plates are detachably fixed to the two short plates respectively. The bottom plate has vertical through holes, the number of which is the same as the number of threaded holes on the mover core and their positions are aligned one-to-one. Each through hole is provided with a bolt, the bolt shank is screwed into the corresponding threaded hole, and the bolt head is pressed against the bottom of the bottom plate.

[0006] In use, the mover is placed horizontally into the rectangular box and pressed onto the base plate, and then completely locked in place with bolts. A columnar plug is installed inside the sealing hole, with one end of each plug sealing the inlet and outlet respectively. Epoxy resin is poured in through the opening of the rectangular box, covering the mover except for the bottom surface of the iron core, and some epoxy resin will enter and seal the outlet hole. After the epoxy resin cools and cures, the rectangular box is disassembled and the bolts are unscrewed to remove the potted mover.

[0007] With the cooperation of through holes, bolts and threaded holes on the mover core, the mover is not only stably positioned in the rectangular box, but also the epoxy resin is prevented from blocking the threaded holes. This allows the sealing of the threaded holes and the positioning of the mover to be carried out simultaneously, effectively reducing the number of operation steps and making it convenient to use. At the same time, the bottom wall of the mover core can be flattened, which is beneficial for subsequent installation.

[0008] In the above-mentioned linear motor mover potting fixture, a strip groove with a width matching the mover core is provided on the bottom wall of the base plate. The length of the strip groove extends along the length direction of the rectangular box. The lower end of the mover core is inserted into the strip groove and can slide along the length direction of the rectangular box to quickly align the through hole and the threaded hole, which facilitates the disassembly and assembly of the mover core, thereby further facilitating the use of the fixture.

[0009] In the aforementioned linear motor mover potting fixture, two long plates and two short plates are respectively attached to the four sides of the base plate, with the two end faces of the long plates attached to the two short plates respectively. Each long plate is detachably connected to the two short plates at both ends by at least one screw, and each long plate is detachably connected to the base plate by at least two screws, with the screws arranged horizontally. This design offers advantages such as simple structure and reliable connection, ensuring a stable potting process.

[0010] In the aforementioned linear motor mover potting fixture, both short plates are detachably fixed to the base plate by at least one horizontally positioned screw to further enhance the structural stability of the rectangular box.

[0011] In the above-mentioned linear motor mover potting fixture, a positioning groove is provided on the side of the long plate, which is directly opposite to the bottom plate and runs through the rectangular box along its length. A sealing strip is provided in the positioning groove, with the two sides of the sealing strip pressing against the bottom wall of the positioning groove and the side of the bottom plate, respectively, and the two ends of the sealing strip pressing against the two short plates.

[0012] In the aforementioned linear motor actuator potting fixture, a U-shaped mounting groove is provided on the side of the short plate near the base plate. A U-shaped sealing sheet that matches the mounting groove is provided in the mounting groove. One end face of the sealing sheet presses against the bottom wall of the mounting groove, while the side of the base plate and the end faces of the two long plates press against the other end face of the sealing sheet.

[0013] With the cooperation of sealing strips and sealing sheets, a reliable seal is formed between the long plate, short plate and base plate to prevent potting leakage.

[0014] In the aforementioned linear motor mover potting fixture, the short plate has a top hole that runs through the rectangular box along its length, and the top hole is located below the sealing sheet.

[0015] In the aforementioned linear motor mover potting fixture, the long plate has a second top hole that extends through the width of the rectangular box, and the second top hole is located below the sealing strip.

[0016] Top hole one and top hole two are respectively provided on the short plate and the long plate, so that in actual use, the mover after potting can be moved by the push rod passing through top hole one or top hole two, so that the mover can be demolded more smoothly and further facilitated.

[0017] In the aforementioned linear motor mover potting fixture, a connecting groove is horizontally threaded through the side of the long plate near the base plate, and the length of the connecting groove extends along the length direction of the rectangular box. The cross-section of the connecting groove is L-shaped, matching the long side of the base plate, and the two long sides of the base plate are respectively inserted into the two connecting grooves. The aforementioned strip groove is set on the inner wall of the connecting groove. With the cooperation of the long plate and the connecting groove, the long plate and the base plate are pre-connected, facilitating subsequent screw installation and positioning.

[0018] In the aforementioned linear motor mover potting fixture, the side of the short plate closest to the long plate has a protrusion. The protrusion is located inside the mounting groove, and the two sides of the protrusion distributed along the width direction of the rectangular box are respectively attached to the two long plates, realizing the pre-connection of the long plate and the short plate, which facilitates the subsequent screw installation and positioning.

[0019] Compared with existing technologies, this linear motor mover dispensing fixture has the following advantages:

[0020] 1. With the cooperation of through holes, bolts and threaded holes on the mover core, the mover is not only stably positioned in the rectangular box, but also the epoxy resin is prevented from blocking the threaded holes. This allows the sealing of the threaded holes and the positioning of the mover to be carried out simultaneously, effectively reducing the number of operation steps and making it convenient to use. At the same time, the bottom wall of the mover core can be flattened, which is conducive to subsequent installation.

[0021] 2. With the cooperation of sealing strips and sealing sheets, a reliable seal is formed between the long plate, short plate and base plate to prevent potting leakage.

[0022] 3.

[0029] like Figure 2 As shown, this linear motor mover potting fixture includes a rectangular box 1 with an open top. The rectangular box 1 is formed by two long plates 2, two short plates 3, and a bottom plate 4. The two long plates 2 are distributed along the width direction of the rectangular box 1, and the two short plates 3 are distributed along the length direction of the rectangular box 1. In actual use, the mover 8 is horizontally placed into the rectangular box 1 through the above-mentioned opening and pressed against the bottom plate 4.

[0030] in,

[0031] One of the short plates 3 is provided with two sealing holes 3a and a wire outlet hole 3b for the electric wire of the mover 8 to extend out, and the two sealing holes 3a are respectively set to face the water inlet 8c and the water outlet 8d of the mover 8.

[0032] Both the short plate 3 and the long plate 2 are detachably fixed to the base plate 4, and both ends of the long plate 2 are detachably fixed to the two short plates 3 respectively. Specifically, the two long plates 2 and the two short plates 3 are respectively attached to the four sides of the base plate 4, and the two ends of the long plates 2 are respectively attached to the two short plates 3. Each end of each long plate 2 is detachably fixed to the two short plates 3 by at least one screw 5; each long plate 2 is detachably fixed to the base plate 4 by at least two screws 5; each short plate 3 is detachably fixed to the base plate 4 by at least one screw 5; the screws 5 are horizontally arranged, and the heads of the screws 5 are outside the rectangular box 1. The above design has the advantages of simple structure and reliable connection, ensuring stable potting process. The number of screws 5 is determined by the length and width of the rectangular box 1, and there is no precise value.

[0033] To further explain, such as Figure 3 and Figure 4As shown, a positioning groove is formed on the side of the long plate 2, directly opposite the base plate 4. The positioning groove is elongated and extends along the length of the rectangular box 1. A sealing strip 6 is provided inside the positioning groove. The two sides of the sealing strip 6 press against the bottom wall of the positioning groove and the side of the base plate 4, respectively, and the two ends of the sealing strip 6 press against the two short plates 3. A U-shaped mounting groove 3e is formed on the side of the short plate 3 near the base plate 4, and the mounting groove 3e and the short plate 3 are coaxially arranged. A U-shaped sealing sheet is provided inside the mounting groove 3e, matching the mounting groove 3e. One end of the sealing sheet presses against the bottom wall of the mounting groove 3e, and the side of the base plate 4 and the ends of the two long plates 2 press against the other end of the sealing sheet. With the cooperation of the sealing strip 6 and the sealing plate, a reliable seal is formed between the long plate 2, the short plate 3 and the bottom plate 4 to prevent potting leakage. At this time, the screws 5 used to connect the short plate 3 and the long plate 2 and the screws 5 used to connect the short plate 3 and the bottom plate 4 are both located outside the sealing plate; the screws 5 used to connect the long plate 2 and the bottom plate 4 are located below the sealing strip 6.

[0034] Furthermore, a connecting groove 2a is horizontally penetrating the side of the long plate 2 near the base plate 4, and the length of the connecting groove 2a extends along the length direction of the rectangular box 1. The cross-section of the connecting groove 2a is L-shaped, matching the long side of the base plate 4, and the two long sides of the base plate 4 are respectively inserted into the two connecting grooves 2a. The aforementioned strip groove 4b is provided on the inner wall of the connecting groove 2a. With the cooperation of the long plate 2 and the connecting groove 2a, the long plate 2 and the base plate 4 are pre-connected, facilitating the subsequent installation and positioning of the screws 5. The short plate 3 has a protrusion 3c on the side near the long plate 2. The protrusion 3c is located inside the mounting groove 3e, and the two sides of the protrusion 3c distributed along the width direction of the rectangular box 1 are respectively attached to the two long plates 2, achieving the pre-connection of the long plate 2 and the short plate 3, facilitating the subsequent installation and positioning of the screws 5.

[0035] like Figure 1 , Figure 2 and Figure 3 As shown, the base plate 4 has vertical through holes 4a. The number of through holes 4a is the same as the number of threaded holes 8e on the iron core 8a of the mover 8, and their positions are directly opposite each other. Each through hole 4a is provided with a bolt 7. The shank of the bolt 7 is screwed into the corresponding threaded hole 8e, and the head of the bolt 7 presses against the bottom of the base plate 4.

[0036] In use, the mover 8 is placed horizontally into the rectangular box 1 and pressed onto the base plate 4, and the mover 8 is completely locked in place by the bolt 7; the sealing hole 3a is equipped with a columnar plug, one end of which seals the inlet 8c and the outlet 8d respectively; epoxy resin is poured in through the opening of the rectangular box 1, covering the part of the mover 8 except for the bottom surface of the iron core 8a, and some epoxy resin will enter the outlet hole 3b and seal it; after the epoxy resin cools and cures, the rectangular box 1 is disassembled and the bolt 7 is unscrewed to remove the mover 8 after it has been filled with epoxy resin.

[0037] With the cooperation of through hole 4a, bolt 7 and threaded hole 8e on the core 8a of mover 8, not only is mover 8 stably positioned in rectangular box 1, but epoxy resin is also prevented from blocking threaded hole 8e, so that the sealing of threaded hole 8e and positioning of mover 8 are carried out simultaneously, effectively reducing operation steps and making it convenient to use. At the same time, the bottom wall of core 8a of mover 8 can be flattened, which is conducive to subsequent installation.

[0038] To further explain, a strip groove 4b with a width matching that of the moving element 8 core 8a is provided on the bottom wall of the base plate 4. The length of the strip groove 4b extends along the length direction of the rectangular box 1. The lower end of the moving element 8 core 8a is inserted into the strip groove 4b and can slide along the length direction of the rectangular box 1 to quickly align the through hole 4a and the threaded hole 8e, which facilitates the disassembly and assembly of the moving element 8 core 8a and further facilitates the use of the tooling.

[0039] In actual products, such as Figure 2 and Figure 4 As shown, the short plate 3 has a top hole 3d extending through the rectangular box 1 along its length, and the top hole 3d is located below the sealing strip. The long plate 2 has a top hole 2b extending through the rectangular box 1 along its width, and the top hole 2b is located below the sealing strip 6. Preferably, each long plate 2 has two top holes 2b, and the two top holes 2b are distributed at both ends of the long plate 2. The top holes 3d and 2b are respectively provided on the short plate 3 and the long plate 2 so that, in actual use, the push rod passing through the top hole 3d or the top hole 2b can push the potted mover 8 to move, making the mover 8 easier to demold and further facilitating its use.
