Description

Linear slide

This creation is a linear guide, especially a linear slide.

Please refer to the fifth figure, which is a conventional slider with a reinforcing device, the slider is sleeved on a rail, and a plurality of rolling bodies are arranged between the slider and the rail, and the sliding is performed by the above The block, the rail and the rolling body form a linear slide, and the rolling body can serve as a medium for the two to reciprocate the slider relative to the rail, and is widely used in various industries, and is developed in response to various industries. Linear slides of different specifications. The structural design of the slider of the fifth figure is applied to the industry of high speed demand, because the speed of the slider (1) during operation is quite fast, so the rolling element inside the slider (1) is reflowed when the end cover (2) is reflowed. The rolling element hits the surface of the return passage (not shown) provided by the end cover (2) at a relatively frequent frequency, and relatively generates vibration, and the rolling element often rushes out at the return passage of the end cover after a long time running. Mainly because the strength of the connecting portion is weak, a reinforcing device (4) is further added to strengthen the portion, and the reinforcing device (4) is provided with an axial groove (41) and a lateral groove (44). a plurality of convex portions (42, 43), the axial grooves (41) and the lateral grooves (44) are alternately arranged, the axial grooves (41) being sleeved by a rail (not shown), The lateral groove (44) is sleeved on the end cover (2), and the plurality of protrusions (42, 43) are provided with a through hole (421, 431), and the slider (1) is provided with the opposite protrusion a recess (11) of the portion (42, 43), the recess (11) is provided with a screw hole (111) opposite to the through hole (421, 431), when the reinforcing device (4) is sleeved on the end cover (2) After the convex portion (42, 43) is received in the concave portion (11), The through hole (421, 431) is disposed opposite to the screw hole (111), and is screwed to the screw hole (111) by a screw (5), and is screwed to the screw hole (111) to The reinforcing device (4) is positioned on the slider (1).
However, since the reinforcing device (4) is locked to the slider (1) by screws (5), a plurality of screw holes (111) must be processed on both ends of the slider (1), and the screw holes are processed (111). In case of inadvertent processing, the rigidity of the slider (1) is also affected. In addition, the reinforcing device (4) is more complicated in manufacturing because of the complicated configuration, and when the reinforcing device (4) is assembled. Because the plurality of screws (5) are to be locked, the assembly time is long, so that the entire manufacturing and assembly time course of the conventional use and the manufacturing and assembly time without the reinforcing device (4) are 20 to 30% longer. Therefore, in view of the foregoing, the structural design of the reinforcing device (4) and the slider (1) is still necessary for improvement and improvement.

In view of the above problems, the main purpose of this creation is to develop a design of the reflow structure to avoid the rolling element running out of the return channel due to the weaker strength of the return channel.
In order to achieve the above purpose, the present invention is a linear slide comprising: a rail which is elongated into a strip-like structure in the direction of extension, defining the direction of elongation as the direction of the axis, and the sides of the axis of the rail Each has a rolling groove; a slider is slidably disposed on the rail, the slider has a rolling groove and two fixing grooves relative to the rolling groove, the rolling groove and the rolling groove form a load path; two reflow elements The reflow elements are respectively formed by a body and two extensions extending from the body, and the reflow elements are U-shaped, and the reflow elements are respectively The extending portion is disposed on the fixing groove, and the two extending portions are butted against each other. When the connecting portion has an annular positioning piece, the annular positioning piece is inserted into the fixing ring of the other extending portion, so that the annular positioning piece is The fixing ring is covered, and the body and the extension portion are provided with a J-type return flow path, and the J-type return flow path forms a return path, and the return flow path is coupled with the load path to form a circulation path; the complex rolling system is designed On the loop path
Preferably, the reflow element comprises: a first member and a second member, the first member having a first body, a first half and a second half, wherein the first half and the second half are The first body extends, the first half has a first half flow channel and a first positioning piece, the second half has a second half flow channel and a second positioning piece; the second component has a second body and a third half and a fourth half, the third half and the fourth half being extended by the second body, the third half having a third half flow channel and a fixing ring, the fourth half a fourth half flow channel and a third positioning piece; the first body and the second body are combined with each other to form the body; the first half and the third half are combined with each other to form the extension; the second half And the fourth half is combined with each other to form the extension; the first semi-flow passage and the third semi-flow passage system constitute the J-type return passage; the second semi-flow passage and the fourth semi-flow passage system constitute the J-shaped The first positioning piece is inserted into the fixing ring; the second positioning piece and the third positioning piece form the annular positioning piece.
