Description

Technical Field

[0001] This utility model relates to a potting tool, and more particularly to a primary structure potting tool for a linear motor. Background Technology

[0002] Linear motors are increasingly widely used in automation and machine tool fields. They are divided into primary and secondary structures. The primary structure mainly consists of coils and an iron core. When current is applied to the primary structure, a traveling wave magnetic field is generated in the air gap between the primary and secondary structures. This traveling wave magnetic field, along with the secondary permanent magnet, generates a driving force, thus achieving linear motion of the moving parts. To enhance the integrity of the primary structure and improve its resistance to external impacts and vibrations, the primary structure of the linear motor needs to be potted with epoxy resin after assembly. This potting also improves the insulation between internal components and circuits, prevents direct exposure of components and circuits, and improves the waterproof and moisture-proof performance of the components.

[0003] For example, Chinese Patent Publication No. CN220234448U discloses a primary structure potting fixture for a linear motor. The base plate design of this primary structure potting fixture is compatible with primary structures of linear motors of different widths. Simultaneously, the spacing between the two movable side plates is adjustable, allowing the primary structure potting fixture to be compatible with primary structures of linear motors of different widths at the same length. A single fixture can be used for primary structures of linear motors in the same series, demonstrating high versatility. The two movable side plates are not fixed to the base plate with screws, effectively simplifying the installation and disassembly steps. The use of a pneumatic push rod mechanism and a pneumatic pressure plate mechanism for fixing and limiting the primary structure makes loading and unloading more convenient, enabling automated installation and fixing, and improving production efficiency. This invention also avoids repeated screw tightening and uses pressure plates to limit and fix the movable side plates, ensuring fixture accuracy while reducing the cost of later maintenance and replacement.

[0004] Some problems were found when using the existing primary structure potting fixture for linear motors. First, the epoxy resin needs to be poured into the fixture for filling the gap, but one side of the device is not blocked, which makes it easy for the epoxy resin to overflow. At the same time, the chute is set on the inside, which makes it easy for epoxy resin to enter the chute during filling the gap. After hardening, it is difficult to clean. Secondly, the extensive use of cylinders and other components leads to high manufacturing costs. Utility Model Content

[0005] The purpose of this invention is to provide a primary structure potting fixture for a linear motor to solve the existing problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a primary structure potting fixture for a linear motor, comprising a heat-conducting base plate and a primary structure. The heat-conducting base plate has several heat-conducting through holes, and connectors are fixedly connected to both ends of each heat-conducting through hole. A heat-insulating conduit is connected between two adjacent connectors. A baffle plate is fixedly connected to the top of the heat-conducting base plate. A first extrusion slope is provided on one side of the baffle plate. A threaded column is fixedly connected to the top of the heat-conducting base plate. An L-shaped extrusion plate is slidably installed on the threaded column. A second extrusion slope is provided on one side of the L-shaped extrusion plate. The second extrusion slope cooperates with the first extrusion slope.

[0007] Preferably, a compression spring is sleeved on the heat-conducting through hole, and a nut is threaded onto the heat-conducting through hole.

[0008] Preferably, the enclosure includes two horizontal baffles and two vertical baffles, with the two horizontal baffles arranged symmetrically front to back and the two vertical baffles arranged symmetrically left to right and front to back.

[0009] Preferably, a limiting block is fixed to one side of the enclosure plate and at both sides of the first extrusion slope.

[0010] Preferably, the L-shaped extrusion plate has a connecting through hole on its underside, and the connecting through hole cooperates with the threaded post.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By cooperating with the first extrusion slope, the extrusion spring provides a certain downward pressure to the L-shaped extrusion plate, thereby providing sufficient thrust and downward pressure to the enclosure plate, so that the enclosure plate can be closed on the heat-conducting base plate. In the later stage, the mold can be disassembled simply by unscrewing the nut. Compared with the existing device, the structure is simple and the cost is greatly reduced.

[0013] 2. By connecting the connectors and the heat-insulating conduits, multiple heat-conducting holes can be connected together. Then, heat or cold medium can be pumped into the heat-conducting holes to quickly control the temperature of the heat-conducting base plate. In the early stage of epoxy resin pouring, the epoxy resin is heated to maintain its fluidity. After the potting is completed, the epoxy resin can be quickly cooled down to accelerate its hardening, thereby effectively improving the potting quality and speed. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a primary structure potting fixture for a linear motor, including a heat-conducting base plate 1 and a primary structure 6. The heat-conducting base plate 1 has a plurality of heat-conducting through holes 101. Connectors 2 are fixedly connected to both ends of the heat-conducting through holes 101. A heat-insulating conduit 3 is connected between two adjacent connectors 2. A baffle plate 4 is fixedly connected to the heat-conducting base plate 1. A first extrusion slope 403 is opened on one side of the baffle plate 4. A threaded post 102 is fixedly connected to the heat-conducting base plate 1. An L-shaped extrusion plate 5 is slidably installed on the threaded post 102. A second extrusion slope 501 is opened on one side of the L-shaped extrusion plate 5. The second extrusion slope 501 cooperates with the first extrusion slope 403.

[0021] In this embodiment, four baffle plates 4 are arranged together to form a groove at the center. The primary structure 6 is placed inside the groove. Then, an L-shaped extrusion plate 5 is fitted onto the threaded post 102, and the second extrusion ramp 501 is aligned with the first extrusion ramp 403. The L-shaped extrusion plate 5 is then pushed down. During this downward movement, the second extrusion ramp 501 and the first extrusion ramp 403 work together to decompose a portion of the downward pressure on the L-shaped extrusion plate 5 into a vertical thrust. Thus, the L-shaped extrusion plate 5 provides thrust and downward pressure to the baffle plates 4, causing the four baffle plates 4 to close together, while simultaneously providing thrust to the central area. The primary structure 6 provides extrusion pressure to compress and fix it, facilitating the subsequent grouting operation. Simultaneously, the connector 2, in conjunction with the heat-insulating conduit 3, connects the internal components of multiple heat-conducting holes 101. Heat or cold medium is then pumped into the heat-conducting holes 101, rapidly transferring heat to the heat-conducting base plate 1. This heats the epoxy resin during the initial pouring stage, maintaining its fluidity and preventing it from hardening. After the final encapsulation, the heat-conducting base plate 1 is cooled, rapidly reducing the epoxy resin's temperature and accelerating its hardening, thus improving both the quality and speed of the encapsulation process.

[0022] In order to provide thrust to the L-shaped extrusion plate 5, the device adopts the following technical solution: a compression spring 103 is sleeved on the heat conduction through hole 101, a nut 104 is threaded on the heat conduction through hole 101, and the baffle plate 4 includes two horizontal baffles 401 and two vertical baffles 402. The two horizontal baffles 401 are symmetrically arranged front and back, and the two vertical baffles 402 are symmetrically arranged left and right and front and back.

[0023] The compression spring 103 is located between the L-shaped compression plate 5 and the nut 104. The compression spring 103 can provide a downward pushing force to the L-shaped compression plate 5. Rotating the nut 104 can compress or release the compression spring 103, thereby changing the downward pushing force of the compression spring 103 on the L-shaped compression plate 5. The enclosure is composed of two sets of horizontal baffles 401 and vertical baffles 402. The vertical baffles 402 abut against both ends of the horizontal baffles 401, so that the connection between the horizontal baffles 401 and the vertical baffles 402 is kept tightly connected. At the same time, rubber seals are provided at both ends and the bottom of the enclosure plate 4, thereby sealing the connection between the enclosure plates 4. The two horizontal baffles 401 are used to clamp and fix the primary structure 6.

[0024] In order to achieve the purpose of restricting the L-shaped extrusion plate 5, the device adopts the following technical solution: a limiting block 404 is fixedly connected to one side of the baffle plate 4 and at both sides of the first extrusion inclined surface 403. A connecting through hole 502 is opened under the L-shaped extrusion plate 5, and the connecting through hole 502 cooperates with the threaded post 102.

[0025] The L-shaped extrusion plate 5 can be restricted by the two limiting blocks 404, so that the L-shaped extrusion plate 5 can only move up and down, and the second extrusion slope 501 and the first extrusion slope 403 can be completely attached together.

[0026] The working principle and usage process of this utility model are as follows: During use, the connector 2, whose two ends are not connected to the heat insulation conduit 3, needs to be connected to an external circulation pump. Four baffles 4 are then assembled together, with the primary structure 6 placed in the center. The nut 104 is then rotated to press down the compression spring 103. The compression spring 103 provides a certain thrust to the L-shaped compression plate 5. The second compression slope 501 cooperates with the first compression slope 403, thereby using the L-shaped compression plate 5 to compress the baffles 4, fixing the primary structure 6 in the center and ensuring a sealed connection at the baffle joint. The circulation pump pumps heat medium into the heat conduction hole 101, allowing epoxy resin to be poured onto the surface of the primary structure 6. This heats the epoxy resin, maintaining its fluidity and preventing it from cooling and hardening. After the potting process, the circulation pump pumps coolant to the heat conduction hole 101, lowering the temperature of the heat conduction base plate 1 and rapidly cooling the epoxy resin, accelerating its hardening.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
