Abstract
The utility model discloses a split permanent magnet fixing device for a permanent magnet linear synchronous motor. The device consists of a magnetic steel fixing plate and two magnetic steel pressing plates. A plurality of cylindrical magnetic isolating pins are arranged on the plate surface of the magnetic steel fixing plate, and are used for isolating magnetic steel to ensure the consistency of polar distances. A magnetic steel pressing plate step is arranged on each of the two sides of the magnetic steel fixing plate. A raised edge is arranged on the upper part of one lateral surface of each magnetic steel pressing plate. The two magnetic steel pressing plates are fixed on the magnetic steel pressing plate steps on the two sides of the magnetic steel fixing plate respectively. The raised edges of the two magnetic steel pressing plates are opposite. According to the split permanent magnet fixing device, the magnetic steel is conveniently and accurately arranged and positioned, the polar distances of the magnetic steel can be ensured, so that the thrust of the permanent magnet linear synchronous motor is highly stable; and the magnetic steel can be prevented from being separated by fixed connection between the aluminum magnetic steel pressing plates and the steps on the two sides of the magnetic steel fixing plate, so that the safety and reliability of the permanent magnet linear synchronous motor can be improved.
Description
Technical field:
The utility model relates to a kind of permanent-magnet linear motor, is a kind of auxiliary of permanent-magnet linear motor specifically.
Background technology:
The permanent-magnet linear synchronous machine has obtained application more and more widely as linear drive system in Digit Control Machine Tool, in other mechanisms, also begin to be applied.In the permanent-magnet linear synchronous machine, the positioning accuracy of permanent magnet and fixed form quality can directly influence the stationarity of motor thrust and the security reliability of motor.The main frock of leaning on is gluing fixing with magnet in the assembling of in the past permanent magnet, because the magnetic field intensity of permanent magnet is very high, the active force between adjacent is very big; And the gluing firmly frock of glue meeting; Make the attaching of permanent magnet relatively more difficult like this, relative position between the magnet steel and positioning accuracy are difficult to be guaranteed, and have influenced the stationarity of permanent-magnet linear synchronous machine thrust; Magnet steel simultaneously fixedly only depends on adhesive glue to fix; The reinforcing anti-drop device that does not have other, the magnet steel bonding impacts the motor safety reliability with making magnet steel break away from the magnet steel fixed head easily behind the glue high temperature ageing like this.
The utility model content:
The purpose of the utility model is to overcome the defective that prior art exists; A kind of relative position and positioning accuracy that can fully guarantee between each permanent magnet is provided; And can make the magnet steel anticreep, thereby make the split type permanent magnet positioner in the stationarity permanent-magnet linear synchronous machine good, safe and reliable, that help to dispel the heat of permanent-magnet linear synchronous machine thrust.
The technical solution of the utility model is: the split type permanent magnet fixture in the permanent-magnet linear synchronous machine; Constitute by a magnet steel fixed head and two magnet steel pressing plates; Said magnet steel fixed head plate face is provided with some at a distance from the magnetic straight pin, is used for magnet steel and isolates, and guarantees the consistency of anode-cathode distance; Magnet steel pressing plate step is respectively established in magnet steel fixed head both sides; The top of a side of said magnet steel pressing plate is provided with the convex edge; Two magnet steel pressing plates are separately fixed on the magnet steel pressing plate step of magnet steel fixed head both sides, and the position, convex edge of two magnet steel pressing plates is relative.
The beneficial effect of the utility model is: the magnet steel installing and locating is accurately convenient; Can guarantee the magnet steel anode-cathode distance; Thereby make the stationarity of permanent-magnet linear synchronous machine thrust good; Aluminium magnet steel pressing plate was fixed with being connected of magnet steel fixed head both sides step can make the magnet steel anticreep, thereby improves the security reliability of permanent-magnet linear synchronous machine.

Embodiment
Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail
Embodiment: as shown in Figure 1, the split type permanent magnet fixture in the utility model permanent-magnet linear synchronous machine is made up of a magnet steel fixed head 1 and two magnet steel pressing plates 2.
As shown in Figure 2, said magnet steel fixed head plate face is provided be arranged in parallel in twos some at a distance from the magnetic straight pin, is used for magnet steel and isolates, and guarantees the consistency of anode-cathode distance; Magnet steel pressing plate step is respectively established in magnet steel fixed head both sides; As shown in Figure 3, the top of a side of said magnet steel pressing plate is provided with convex edge 5; Be useful on the screwed hole 4 that connection is used on the magnet steel pressing plate step; Two magnet steel pressing plates are separately fixed on the magnet steel pressing plate step of magnet steel fixed head both sides through screw; The convex edge of magnet steel pressing plate embeds in the magnet steel corresponding grooves, can magnet steel be carried out anticreep and fix.
Fig. 2 is a magnet steel fixed head structural representation; With machine work magnet steel fixed head main part is processed earlier; And manufacture straight pin at the magnet steel wall-attached surface; So promptly help guaranteeing the flatness of magnet steel wall-attached surface, help the precision of magnet steel again, thereby make the stationarity of permanent-magnet linear synchronous machine thrust good at a distance from magnetic.
Fig. 3, Fig. 4 are the structural representations of magnet steel pressing plate; With screw aluminium magnet steel pressing plate and magnet steel fixed head both sides step are fastenedly connected, the position, convex edge of two magnet steel pressing plates is relative, cooperates with corresponding grooves on the magnet steel; Just can be with the magnet steel stationary positioned; Realization is to the reinforcing anticreep of magnet steel, and the magnet steel pressing plate is an aluminium with material simultaneously, helps the stationary part heat radiation.
