Detailed Description
Specific examples of the present invention will be described in further detail below. It should be understood that the description herein of embodiments of the invention is not intended to limit the scope of the invention.
As shown in fig. 1 to 5, which are schematic structural views of the high-stability linear motor type guide rail provided by the present invention. The high-stability linear motor type guide rail comprises two bases 10 arranged at intervals, two guide rods 20 arranged at intervals and respectively arranged between the two bases 10, a linear motor assembly 30 erected on the two guide rods 20, a sliding assembly 40 erected on the guide rods 20 and connected with the linear motor assembly 30, and a drag chain assembly 50 arranged on the bases 10. It is contemplated that the high stability linear motor type guide rail may further include other functional modules, such as assembly components, electrical connection components, etc., which are well known to those skilled in the art and will not be described in detail herein.
The base 10 can be arranged according to actual needs and can be fixed on some additional equipment for erecting parts such as the guide rod 20.
The two guide rods 20 have the same structure and they may be made of stainless steel or aluminum profile. The guide rod 20 may be circular, or square, or other shapes. In this embodiment, the guide bar 20 has a square shape. The guide bar 20 comprises two trapezoidal guide grooves 21 arranged opposite to each other in a cross section perpendicular to the sliding direction of the sliding assembly 40. The trapezoid guide grooves 21 are isosceles trapezoids, the heights of the two trapezoid guide grooves 21 arranged on the guide rod 20 are parallel to each other, and the arrangement direction of the two trapezoid guide grooves 21 is the same as that of the two guide rods 20. Two ends of the guide rod 20 are fixed on the two bases 10 and are spaced to arrange the linear motor assembly 30.
The linear motor assembly 30 includes a secondary rod 31 disposed between two of the bases 10, and a primary assembly 32 fitted over the secondary rod 31. The linear motor assembly 30 is a conventional linear motor assembly, and its working principle is that a magnetic flux generated in the primary assembly 32 after the alternating current is introduced induces an eddy current on the secondary rod 31 of the moving body according to lenz's law. Assuming that the induced voltage causing the eddy current is E, the secondary rod 31 has an inductance L and a resistance R, and the eddy current and the magnetic flux density will generate a continuous thrust F according to the fisher-minting law, so that the primary assembly 32 slides along the secondary rod 31, and further the primary assembly 32 is driven to slide along the secondary rod 31. It is conceivable that the secondary lever 31 is a circular lever. Due to the existence of the linear motor assembly 30, repeated and accurate positioning can be achieved, and the precision of the whole guide rail is improved.
The sliding assembly 40 includes a sliding seat 41 fixedly disposed on the primary assembly 32, at least two sliding blocks 42 respectively disposed between the sliding seat 41 and the guide rods 20, and at least two rollers 43 disposed on the sliding seat 41 and respectively abutted against the two guide rods 20. The sliding seat 41, which may be made of a lightweight material such as plastic, is fixed to the primary assembly 32 to slide with the primary assembly 32, so that when a device is placed on the sliding seat 41, the device can be driven to slide together. Two through slots 411 are arranged on the sliding seat 41. The extending direction of the two through slots 411 is the same as the axial direction of the two guide rods 20. The sliding block 42 is fixedly disposed on the through groove 41 and has a trapezoidal boss 421. The trapezoid boss 421 is engaged with the trapezoid guide slot 21, two waists of the trapezoid boss 421 are respectively abutted against two waists of the trapezoid guide slot 21, and an upper bottom of the trapezoid boss 421 and an upper bottom of the trapezoid guide slot 21 are arranged at an interval. Because the two waists with a certain angle can reduce the gap existing due to errors, the two waists of the trapezoidal boss 421 are always abutted against the two waists of the trapezoidal guide groove 21, and thus the stability between the sliding block 42 and the guide rod 20 can be ensured. In addition, to reduce friction and improve temperature resistance, the slider assembly 40 includes a wear plate 44 disposed on the slider 42. The wear-resistant sheet 44 is wrapped on the outer side wall of the trapezoid boss 421 and made of wear-resistant material, so that the friction system is reduced, and the service life of the linear motor type guide rail is prolonged. The two rollers 43 are identical in structure and include a shaft 431 fixed to the sliding seat 41, a wheel 432 sleeved on the shaft 431, and at least one bearing 433 disposed between the shaft 431 and the wheel 432. The shaft 431, the bearing 433 themselves, and the connection and fixation between the shaft 431 and the bearing 433 should be the prior art, and are not described herein again. The wheel 432 has a trapezoidal edge 434, and the size of the trapezoidal edge 434 is the same as that of the trapezoidal guide slot 21, such as the angle between two waists and the upper and lower bottoms, the length of the upper bottom, etc., so that when the trapezoidal edge 434 of the wheel 432 abuts against the trapezoidal guide slot 21 of the guide rod 20, the two waists of the trapezoidal edge 434 and the two waists of the trapezoidal guide slot 21 are attached to each other, thereby achieving the purpose of guiding. When the rollers 43 are provided, the axial direction of each roller 43 is perpendicular to the sliding direction of the sliding seat 41 and two rollers 43 are provided between the two guide rods 20. Preferably, the axial direction of the two rollers 43 is perpendicular to the plane of the arrangement direction of the two guide rods 20, so that the two wheels 431 only play a role of guiding without bearing weight and further without deformation, thereby ensuring that the guiding accuracy is not reduced for a long time.
The drag chain assembly 50 includes a guard 51 installed between two bases 10, a drag chain 52 having one end installed on one of the two bases 10, and a link 53 connected between the other end of the drag chain 52 and the sliding seat 41. The protective cover 51 is used for protecting the drag chain 52 from being damaged by dropping sundries into the chain blocks coupled with each other. The drag chain 52 is prior art in itself, and one end thereof can slide with the sliding seat 41, while the other end is fixed. The connecting element 53 is used to connect the drag chain 52 with the sliding seat 41, and can be designed according to actual needs, and will not be described in detail here.
Compared with the prior art, the high-stability linear motor type guide rail provided by the invention uses two guide rods 20, one linear motor assembly 30 arranged between the two guide rods 20, and the sliding assembly 40 is arranged on the linear motor assembly 30, and the sliding assembly 40 comprises a sliding seat 41, at least two sliding blocks 42 respectively arranged between the sliding seat 41 and the guide rods 20, and at least two rollers 43 arranged on the sliding seat 41 and respectively abutted against the two guide rods 20. The linear motor 30 can achieve repeated and accurate positioning, and the precision of the whole guide rail is improved. The slide block 42 is easy to maintain and reduces the coefficient of friction between the guide rod 20 and the slide seat 41, thereby increasing the speed while increasing the load. Meanwhile, the sliding precision of the sliding seat 42 can be ensured through the wear-resistant and high-temperature-resistant design of the sliding block 42. Due to the existence of the roller 43, and the two rollers 43 are disposed between the two guide rods 20, and the axial direction of each roller 43 is perpendicular to the sliding direction of the sliding seat 41, so that the roller 43 is not stressed but only plays a role of guiding, in particular, the guide rods 20 are provided with at least two trapezoidal guide grooves 21, and the roller 43 is provided with a trapezoidal edge 434, and the trapezoidal edge 434 abuts against the waist of the trapezoidal guide groove 21 and is spaced from the upper bottom of the trapezoidal guide groove 21, so that the stability of the sliding seat 41 when sliding along the guide rods 20 can be improved, that is, the stability of the sliding seat 41 is ensured under the combined action of the abutting guide of the roller 43 and the sliding guide of the sliding block 42.
