Description

Technical Field

[0001] This utility model relates to a linear motor displacement stage, specifically to a motor mounting structure for the linear motor displacement stage. Background Technology

[0002] A linear motor is a transmission device that directly converts electrical energy into linear motion mechanical energy without any intermediate conversion mechanism. It can be viewed as a rotary motor cut radially and unfolded into a plane. Linear motors are also called linear motors, linear actuators, or push rod motors. The most common types of linear motors are flat plate, U-slot, and tubular coils. The typical composition is three-phase, with brushless commutation achieved by Hall elements. The control of linear motors is similar to that of rotary motors. Like brushless rotary motors, the mover and stator are not mechanically connected. Unlike rotary motors, where the mover rotates and the stator position remains fixed, linear motor systems can be magnetically driven or driven by a thrust coil. Most positioning systems use a fixed magnetic track and a moving thrust coil. Motors using a thrust coil have a small weight and load ratio, but require highly flexible cables and their management systems. Motors using a magnetic track must bear not only the load but also the mass of the magnetic track, but do not require a cable management system.

[0003] Existing linear motor displacement tables lack a quick-installation mechanism for the motor. The motors are mostly bolted, which makes it inconvenient to quickly disassemble and assemble them, and consequently, to perform maintenance and other operations on the motor. Utility Model Content

[0004] The main objective of this disclosure is to provide a linear motor displacement stage motor mounting structure to effectively solve the problems raised by the inventors in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A linear motor displacement stage motor mounting structure includes a displacement stage body. A horizontally arranged linear slide rail is fixedly mounted on the top of the displacement stage body, and a motor mounting base is movably mounted above the linear slide rail. A mounting port for mounting a motor is opened at the center of the top of the motor mounting base. Perforated frames are fixedly mounted on the front and rear sides of the top of the motor mounting base. A reciprocating bar is slidably mounted through each of the perforated frames. Positioning clamps are fixedly connected to the sides of two reciprocating bars that are close to each other, and the positioning clamps extend above the mounting port.

[0007] Preferably, an eighth-sized sphere is fixedly connected to the end of the reciprocating bar away from the positioning clamp, and a compression spring is fixedly connected between the eighth-sized sphere and the perforating frame, with the reciprocating bar passing through the compression spring.

[0008] Preferably, the top of the displacement table body is fixedly connected to two parallel vertical bars, the motor mounting base is located between the two vertical bars, and the two one-eighth spheres are respectively abutted against the adjacent sides of the two vertical bars.

[0009] Preferably, an anti-slip pad is fixedly connected to the positioning clamp.

[0010] Preferably, an X-axis linear screw is rotatably installed in the groove of the linear slide rail, and a limiting slide rod parallel to the X-axis linear screw is fixedly installed in the groove. A displacement slide is threaded onto the X-axis linear screw, and the displacement slide is slidably installed through the limiting slide rod. The top of the displacement slide extends outside the linear slide rail and is fixedly connected to the motor mounting base.

[0011] Preferably, the left end of the X-axis linear lead screw extends to the outside of the linear slide rail and is fixedly connected to a driven gear. A servo motor is fixedly installed on the displacement stage body, and the output end of the servo motor is fixedly connected to a driving gear. The driving gear meshes with the driven gear.

[0012] In view of this, compared with the prior art, the beneficial effects of this utility model are:

[0013] (i) In this application, the motor is placed at the mounting port, and two eighth-balls are pressed against each other, and the motor mounting base is moved between the two vertical stops, that is, the vertical stops abut against the eighth-balls to prevent loosening. When the two eighth-balls move towards each other, the reciprocating bar drives the positioning clamp to move, the compression spring is compressed, and then the two positioning clamps close and fix the motor, so as to realize the rapid installation of the motor. During the displacement of the motor mounting base, the vertical stops always limit the eighth-balls, thereby ensuring the secure installation of the motor during the movement.

[0014] (ii) In this application, the servo motor works and can drive the X-axis linear screw to rotate, so that the displacement slide moves along the limit slide bar in the linear slide rail, thereby causing the motor mounting base to drive the motor to move. When removing the motor, the motor mounting base is moved out between the two vertical stops, that is, the vertical stops no longer abut against the one-eighth ball. Under the elastic force of the compression spring, the two positioning clamps immediately move apart to release the motor, making disassembly and assembly very convenient.

Detailed Implementation

[0020] 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.

[0021] Please see Figs. 1-3 The present invention provides the following embodiments:

[0022] A linear motor displacement stage motor mounting structure includes a displacement stage body 1. A horizontally arranged linear slide rail 2 is fixedly installed on the top of the displacement stage body 1, and a motor mounting base 3 is movably installed above the linear slide rail 2. A mounting port for placing a motor is opened at the center of the top of the motor mounting base 3. A through-hole frame 4 is fixedly installed on the front and rear sides of the top of the motor mounting base 3. A reciprocating bar is slidably installed on each through-hole frame 4. A positioning clamp 5 is fixedly connected to the side of two reciprocating bars that are close to each other, and the positioning clamp 5 extends above the mounting port.

[0023] Specifically, an eighth-ball 6 is fixedly connected to the end of the reciprocating bar away from the positioning clamp 5, and a compression spring 8 is fixedly connected between the eighth-ball 6 and the perforating frame 4. The reciprocating bar passes through the compression spring 8. Two parallel vertical stops 7 are fixedly connected to the top of the displacement table body 1. The motor mounting base 3 is located between the two vertical stops 7, and the ends of the two eighth-balls 6 that are far apart abut against the sides of the two vertical stops 7 that are close to each other. The length of the vertical stops 7 is smaller than the length of the linear slide rail 2.

[0024] Specifically, anti-slip pads are fixedly connected to the positioning clamp 5 to increase friction.

[0025] Specifically, an X-axis linear screw 9 is rotatably installed in the groove of the linear slide rail 2, and a limiting slide rod 10 parallel to the X-axis linear screw 9 is fixedly installed in the groove. A displacement slide block 11 is threaded onto the X-axis linear screw 9, and the displacement slide block 11 is slidably installed through the limiting slide rod 10. The top of the displacement slide block 11 extends to the outside of the linear slide rail 2 and is fixedly connected to the motor mounting base 3. The left end of the X-axis linear screw 9 extends to the outside of the linear slide rail 2 and is fixedly connected to the driven gear 14. A servo motor 12 is fixedly installed on the displacement table body 1, and a driving gear 13 is fixedly connected to the output end of the servo motor 12. The driving gear 13 meshes with the driven gear 14.

[0026] The specific implementation method of this embodiment is as follows: the motor is placed at the mounting port, the two eighth balls 6 are pressed towards each other, and the motor mounting base 3 is moved between the two vertical stops 7, that is, the vertical stops 7 abut against the eighth balls 6 to prevent loosening. When the two eighth balls 6 move towards each other, the reciprocating bar drives the positioning clamp 5 to move, the compression spring 8 is compressed, and then the two positioning clamps 5 close and fix the motor, so as to realize the quick installation of the motor. During the displacement process of the motor mounting base 3, the vertical stops 7 always limit the eighth balls 6, thereby ensuring the firm installation of the motor during the movement process.

[0027] When the servo motor 12 is working, it can drive the X-axis linear screw 9 to rotate, causing the displacement slide 11 to move along the limit slide 10 within the linear slide rail 2. This, in turn, causes the motor mounting base 3 to move the motor. When removing the motor, the motor mounting base 3 is moved out between the two vertical stops 7, meaning the vertical stops 7 no longer abut against the one-eighth ball 6. Under the elastic force of the compression spring 8, the two positioning clamps 5 immediately move apart to release the motor, making disassembly and assembly very convenient.
