The pure linear-rail ram has the disadvantages of poor rigidity and the cutting force it can bear is not as high as that of the hard-rail surface. Its advantages are fast moving speed, high precision, convenient maintenance, and long service life. How to balance the advantages of pure hard-rail rams and pure linear-rail rams is one of the difficulties in the current slide rail design. Content of the Utility Model

In addition, terms such as "first", "second", "third", etc. are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.
[0020] In the description of the present utility model, it should be noted that, unless otherwise clearly specified and defined, the terms "connected" and "connected to" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.
[0021] Refer to Figures 1-4 As shown, as an embodiment of the present utility model, a hard-wired double-rail combined ram is provided, specifically a hard-wired double-rail combined ram for the Z-axis of a gantry center, including a ram body 1 in the shape of a cuboid. Linear guide positions 2 are respectively arranged on the left and right sides of the ram body 1, and linear guides 4 are installed at the linear guide positions 2. Hard guide positions 3 are respectively arranged on the front and rear sides of the ram body 1. The linear guide position 2 and the hard guide position 3 on one side are reference installation positions, and the linear guide position 2 and the hard guide position 3 on the other side are adjustment installation positions. Specifically, the linear guide position 2 on the right side and the hard guide position 3 on the rear side are reference installation positions, and the linear guide position 2 on the left side and the hard guide position 3 on the front side are adjustment installation positions. That is, a fixed connection plate needs to be installed at the slider 7 corresponding to the linear guide position 2 on the left side for adaptive adjustment and fixation of the slide base, and a strip needs to be installed at the hard guide position 3 on the front side for adaptive adjustment and fixation of the slide base, so as to avoid the hard-wired double-rail combined ram from being unable to be accurately installed on the slide base of the gantry center due to over-positioning. This technical solution combines the hybrid rail connection ram method of hard rails and linear guides 4, making this hard-wired double-rail combined ram take into account the advantages of pure hard-rail rams and pure linear-guide rams, with better rigidity, faster feed speed, thereby improving the machining efficiency of the machine tool, high position accuracy, capable of performing complex machining, high machining accuracy, convenient maintenance, low machining and maintenance costs, high smoothness, and long service life.
[0022] In this embodiment, a linear guide position 2 is provided on each of the left and right sides of the ram body 1, and a linear guide 4 is correspondingly installed at each linear guide position 2. Two hard guide positions 3 are provided on each of the front and rear sides of the ram body 1. The two hard guide positions 3 on the same side are hard guide positions 3 with a stepped structure arranged oppositely, ensuring the installation of the slide seat and the stability of the sliding movement.
[0023] In this embodiment, a pressing block 5 and a blocking step 6 are provided at the linear guide position 2. The pressing block 5 and the blocking step 6 respectively abut and limit the front side and the rear side of the linear guide 4 to prevent the linear guide 4 from loosening in the front-rear direction (lateral direction). That is, the linear guide 4 is fixedly installed at the linear guide position 2 through a locking member. After the rear side of the linear guide 4 abuts and cooperates with the blocking step 6, the pressing block 5 is locked to abut and cooperate with the front side of the linear guide 4, thereby improving the limiting stability of the linear guide 4.
[0024] In this embodiment, the pressing block 5 is hexagonal, and there are multiple pressing blocks 5, further improving the limiting stability of the linear guide 4.
[0025] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes made to the present invention in form and detail without departing from the spirit and scope of the present invention defined by the appended claims all fall within the protection scope of the present invention.
