Linear slide with reinforced device

The invention is a linear transmission element, in particular a linear slide with a reinforcing device.

Referring to FIG. 1 , it 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. The rail and the rolling body form a linear slide which 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. The linear slide of the specification, and the structural design of the slider of Figure 1 is applied to the industry of high speed demand, because the speed of the slider (1) during operation is quite fast, so the rolling body inside the slider (1) is at the end When the 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 the vibration is relatively generated, so that the end cover (2) and the slider are prevented from being fixed. (1) The screw is loose, and a reinforcing device (4) is further installed. The reinforcing device (4) is provided with an axial groove (41), a lateral groove (44), and a plurality of convex portions (42, 43), the axial groove (41) and the lateral groove (44) are mutually staggered, and the axial groove (41) is sleeved by a rail (not shown), the horizontal A recess (44) provided in the sleeve cap line (2), and the plurality of convex portions (42, 43) is provided with a perforated line (421, 431), The slider (1) is provided with a concave portion (11) opposite to the convex portion (42, 43), and the concave portion (11) is provided with a screw hole (111) opposite to the through hole (421, 431), when the reinforcement After the device (4) is sleeved on the end cover (2), the convex portion (42, 43) is received in the concave portion (11), and the through hole (421, 431) is disposed opposite to the screw hole (111). And the screw (5) is threaded and locked with the screw hole (111) after being inserted through the hole (421, 431) to position the reinforcing device (4) on the slider (1). And the end cover (2) can be prevented from being loosened when the slider (1) is running, thereby increasing the speed at which the slider (1) can move.

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.

Based on the problems of the above-mentioned conventional techniques, the inventors of the present invention have succeeded in research and development, and the inventions which can achieve the object of the following inventions are finally born.

That is, the object of the present invention is to develop a reinforcing device that does not need to be screwed to the slider, nor does it need to machine any structure on the slider to cooperate with the reinforcing device.
