For purposes of clarity, many practical details will be set forth in the following description. However, the reader should appreciate that these practical details should not be used to limit the invention. That is, in some embodiments of the invention, these practical details are unnecessary. Moreover, for the sake of simplicity of the drawing, some well-known and conventional structures and elements are shown in the drawings in a simplified schematic manner; and repeated elements will likely be indicated by identical or analogous numerals.
In addition, the terms first, second, third, etc. are used herein only to describe different elements or components, and there is no limitation on the elements/components themselves, and thus, the first element/component may be modified as a second element/component. And the combination of elements/components/mechanisms/modules herein is not a common, conventional or known combination in the art, and it is not possible to determine whether the combination of elements/components/mechanisms/modules is easily accomplished by a person of ordinary skill in the art by whether the combination of elements/components/mechanisms/modules is known per se.
Referring to fig. 1, 2 and 3, fig. 1 is a perspective view of a linear slider 100 according to a first embodiment of the present invention, fig. 2 is an exploded view of the linear slider 100 according to the first embodiment of fig. 1, and fig. 3 is a front view of the linear slider 100 according to the first embodiment of fig. 1. As shown in fig. 1 to 3, the linear slider 100 includes a first component 110 and a second component 120. The first component 110 is made of a metal material and includes a sliding base 111, two ball sliding rails 112 and two ball through holes 113. The second component 120 is made of a non-metallic composite material, and the second component 120 is mounted to the first component 110. The ball sliding rail 112 is integrally disposed at two sides of the sliding base body 111 and extends along an axial direction. The ball through holes 113 axially penetrate through the slide body 111, and the two ball through holes 113 are arranged at intervals. By combining the first component 110 made of metal material with the second component 120 made of non-metal composite material, the weight of the linear slider 100 can be reduced, and the ball sliding rail 112 and the ball through hole 113 for sliding the balls are integrally arranged on the sliding base body 111 made of wear-resistant and rigid metal material, so that the balls only contact with the first component 110 made of metal material. Therefore, the assembly process of the linear slide block 100 can be simplified, the linear slide block 100 can be light, the rolling smoothness of the balls can be maintained, and the possibility of the service life of the linear slide block 100 being reduced due to the light weight can be avoided.
Specifically, the first component 110 may further include a plurality of supporting members 114, each supporting member 114 is disposed on the slide body 111 at intervals, and the second component 120 may include a plurality of engaging holes 121, and each supporting member 114 is inserted into each engaging hole 121. The first component 110 and the second component 120 can be combined by inserting the supporting member 114 into the engaging hole 121, and the supporting member 114 can disperse the external force acting on the second component 120 on the first component 110 made of high-strength metal material, thereby reducing the possibility of damage of the second component 120 due to stress.
Further, each support 114 may include a cylindrical pin 1141 and a horizontal pin 1142, and the height of each cylindrical pin 1141 along a depth direction of the vertical axis is greater than the height of each horizontal pin 1142. Furthermore, each of the engaging holes 121 may include a circular hole penetrating the body of the second component 120 along the depth direction, and the height of each cylindrical pin 1141 is the same as the height of the circular hole along the depth direction. As shown in fig. 2 and 3, carefully speaking, the cylindrical pins 1141 and the horizontal pins 1142 are integrally connected, the shape of each engagement hole 121 corresponds to the shape of each supporting member 114 including the cylindrical pins 1141 and the horizontal pins 1142, that is, includes a circular hole and a rectangular hole, and the stability of the supporting member 114 engaged with the engagement hole 121 can be improved by the arrangement of the cylindrical pins 1141 and the horizontal pins 1142, so as to prevent the second component 120 from falling off from the first component 110 due to external force. Furthermore, the circular holes are configured along the height of the depth direction, so as to further provide a complete supporting force for the second component 120, thereby reducing the external force born by the second component 120.
The second component 120 may be adhesively secured to the first component 110. In detail, the surface of the engaging hole 121 of the second component 120 and the surface contacting the upper surface of the first component 110 may be coated with an adhesive, so that the second component 120 is glued and fixed to the first component 110, but the invention is not limited thereto. Thereby, the stability of the combination of the first component 110 and the second component 120 can be increased.
In the embodiment of fig. 1 to 3, the metal material may be a wear-resistant and high-strength rigid material, such as steel, and the non-metal composite material may be a high-strength plastic, such as carbon fiber or fiber reinforced plastic (Fiber Reinforced Plastics; FRP), but the invention is not limited thereto.
In other embodiments, the second component may be bonded to the first component in a thermocompression bond. Specifically, the first component and the second component are heated first, the surface of the second component is in a molten state, and then the molten second component is mounted on the first component in a pressurizing mode. Therefore, the process of installing the second component on the first component can be simplified, and the bonding strength of the first component and the second component can be increased.
Referring to fig. 4, a schematic diagram of an actuating device 10 according to a second embodiment of the invention is shown. As shown in fig. 4, the actuating device 10 includes a guide rail 200, a linear slider 11 and a plurality of balls 13.

The ball guide 220 is made of a metal material, and the ball guide 220 is disposed inside the track body 210. The linear slider 11 is slidably disposed on the guide rail 200, and specifically, the linear slider 11 may be the linear slider 100 of the first embodiment, which is not described herein. The balls 13 are rollably disposed between the ball guide 220 and the linear slider 100. By the guide rail 200 and the linear slider 11 made of the nonmetallic composite material and the metallic material, the weight reduction of the actuator 10 can be achieved while maintaining the smoothness of rolling of the balls 13.
Furthermore, the rail body 210 may be coupled to the ball guide 220 in a thermo-compression bonding manner. Thereby, the strength of the coupling of the rail body 210 and the ball guide 220 is increased.
Referring to fig. 5, a schematic diagram of a guide rail of an actuating device according to a third embodiment of the invention is shown. In the third embodiment, the structure and configuration of the linear slider (not shown in fig. 5) of the actuating device can be the same as those of the linear slider 100 of the first embodiment, and will not be repeated here. As shown in fig. 5, the guiding track of the actuating device includes a track body 310 and two ball guide tracks 320. The track body 310 is made of a non-metallic composite material. The ball guide 320 is made of a metal material, and the ball guide 320 is disposed inside the track body 310. In particular, the track body 310 may include a plurality of protruding structures 311, each ball rail 320 may include a plurality of engaging grooves 321, and a portion of the protruding structures 311 is engaged with the engaging groove 321 of one ball rail 320, and another portion of the protruding structures 311 is engaged with the engaging groove 321 of another ball rail 320.
Specifically, the protruding structures 311 may be respectively arranged at intervals on two inner sides of the track body 310 in the sliding direction (i.e., the axial direction) of the linear slider. The protruding structure 311 is engaged with the engaging groove 321 of the ball guide 320, so as to increase the strength of the combination of the track body 310 and the ball guide 320, and prevent the ball guide 320 from falling off from the track body 310 due to external force.
