Description

TECHNICAL FIELD

[0001] The utility model belongs to linear multi-shaft transmission technical field, concretely relates to a linear motor module. BACKGROUND

[0002] The double-drive gantry motion platform is a transmission mode when the linear transmission span is long. Figure 1 As shown in the accompanying drawings, it is composed of two connecting plates (C) connected to the two ends of a horizontal linear transmission shaft (A) and two linear shafts (B) capable of synchronous linear motion, forming a structure like a door frame. The length of the linear transmission shaft (A) is determined by the distance between the two linear shafts (B) capable of synchronous linear motion.

[0003] The precision of the double-drive gantry linear motor motion platform is usually high, and the distance between the two linear transmission shafts capable of synchronous linear motion is usually large. Therefore, if the overall strength of the horizontal shaft is not enough, the two synchronous shafts will be deformed due to the large span, affecting the performance of the equipment.

[0004] The conventional solution is to install a conventional linear module (A) on one side and then connect it with multiple connecting plates (C).

[0005] The existing method has the following disadvantages:

[0006] 1. The multiple connecting plates (C) are used as supports, which makes the structure more complex and the manufacturing cost higher.

[0007] 2. The multiple connecting plates (C) will cause cumulative geometric precision errors due to the large number of machining and assembly surfaces, affecting the precision of the equipment.

[0008] 3. The installation and assembly precision of the conventional linear module (A) and the connecting plate (C) is difficult to control, and the cumulative error is more likely to occur during assembly, affecting the precision.

[0009] 4. The conventional linear module (A) will produce a longer span when the distance between the two linear shafts (B) capable of synchronous linear motion is too large, which is more prone to deformation and more prone to shaking during equipment operation.

[0010] Therefore, a linear motor module is needed to solve the problems of large running precision error and high manufacturing and assembly difficulty in the prior art. INVENTION CONTENTS

[0011] The utility model aims to provide a linear motor module to solve the problems in the background art.

[0012] In order to achieve the above object, the utility model provides the following technical scheme: a linear motor module, including linear module, the linear module includes integral type high strength crossbeam, linear motor stator, linear motor mobile, linear guide and sliding plate, the linear motor stator is installed to integral type high strength crossbeam left side and is assembled with linear motor mobile on integral type high strength crossbeam, the linear guide is located integral type high strength crossbeam left side surface, the sliding plate is installed through linear motor mobile on linear guide.

[0013] It needs to be explained in the scheme that the integral type high strength crossbeam section is triangularly arranged, the integral type high strength crossbeam inner chamber is provided with a rib, and a T-shaped groove is formed in the right surface of the integral type high strength crossbeam.

[0014] It is further worth mentioning that the integral type high strength crossbeam is formed by one-time extrusion of a large-tonnage profile extruder.

[0015] Compared with the prior art, the linear motor module provided by the utility model has at least the following beneficial effects:

[0016] (1) The main body of the linear motor module special for the gantry double-drive motion platform is the integral type high strength crossbeam, which is formed by one-time extrusion of a large-tonnage profile extruder, and is integrated. The integral type high strength crossbeam has high stability and high rigidity and is not easy to deform, and can meet the precision requirement more easily. The cumulative geometric precision error caused by the more machining and assembling surfaces is eliminated by the integral design, and the precision is ensured. The integral design can also save the connecting plate and the assembling error between the connecting plate and the linear shaft of the synchronous linear motion, and the precision is further improved.

[0017] (2) By adopting the linear motor transmission, the linear motor stator and the linear motor mobile are assembled on the module in an integrated manner, and the rigidity of the integral type high strength crossbeam can further exert the high running speed, high response speed and high positioning precision of the linear motor, so as to minimize the cumulative geometric precision error caused by the more machining and assembling surfaces and improve the equipment precision.
