[0002] A gantry machining center is a machining center in which the axis of the spindle Z axis is vertically arranged with the worktable. The overall structure is a large-scale machining center with a gantry structure frame composed of double columns and a top beam. There is also a crossbeam in the middle of the double columns. It is especially suitable for machining large workpieces and workpieces with complex shapes. The ram is another movable mechanism superimposed on a movable mechanism on a machine tool. For example, the base of the turret on a lathe, the boring spindle of a boring and milling machine, the W axis on a moving beam gantry, etc. can all be called a ram.

[0003] In the Chinese Patent Literature Library, the patent with application number 202220358684.2 discloses a ram of a CNC gantry machining center that is easy to install. By setting guide plates and connecting plates, when the ram needs to be inspected and maintained, the top piece at the top is driven to move and open to both sides by adjusting the position of the guide plates and the connecting plates, so as to facilitate the removal of the ram. However, in actual use, it is time-consuming and laborious to adjust each guide plate and connecting plate one by one. At the same time, there are multiple guide plates, which slide relative to the ram. When the guide plates enter the guide grooves on the sides of the ram, when the sizes deviate, it is easy to cause wear on both. Summary of the invention

[0018] See also Figure 1-4 The utility model provides an embodiment: a gantry machining center slide that is easy to inspect and maintain, including a moving part 1 and a slide body 2 slidably arranged on the inner side of the moving part 1, and limit stops 3 for limiting the slide body 2 are arranged on both sides of the top of the moving part 1, and the two limit stops 3 are respectively slidably connected to the two sides of the slide body 2, and the limit stops 3 are adapted to the length of the moving part 1, and guide grooves are symmetrically arranged on both sides of the slide body 2 along its length direction. A guide rail matching the guide groove is arranged on the side of the limit stop 3 close to the slide body 2, and the guide rail always slides inside the guide groove, which can avoid wear caused by errors in the positions of the slide body 2 and the limit stops 3 when the guide rail of the slide body 2 moves out of the guide groove.

[0019] The bottom end of the moving member 1 is provided with an adjusting mechanism 4 for adjusting the distance between the two limit blocks 3. The bottom end of the moving member 1 is provided with an upwardly recessed mounting groove. The adjusting mechanism 4 is arranged inside the mounting groove. Specifically, the adjusting mechanism 4 includes a linear driving member 401 for pushing any one of the limit blocks 3 to move horizontally along the width direction of the moving member 1 and a centering adjustment component connecting the two limit blocks 3. The linear driving member 401 can be any one of an oil cylinder, an air cylinder, etc., and is horizontally fixed to the bottom end of the moving member 1 through a mounting plate.

[0020] The centering adjustment component includes a first connecting rod 402 rotatably arranged at the bottom end of the moving member 1, two second connecting rods 403 and two connecting brackets 404 fixedly connected to the two limit blocks 3 respectively. The middle of the first connecting rod 402 is rotatably connected to the bottom end of the moving member 1, one end of the two second connecting rods 403 is rotatably connected to the two ends of the first connecting rod 402 respectively, and the other ends of the two second connecting rods 403 are fixedly connected to the two connecting brackets 404 respectively. When any connecting bracket 404 pushes the second connecting rod 403 connected thereto to rotate, the second connecting rod 403 pushes the first connecting rod 402 to rotate, and then drives the connecting bracket 404 on the other side to move in the opposite direction through the second connecting rod 403 on the other side, so that the positions of the two limit blocks 3 can be adjusted synchronously. Because the guide grooves on both sides of the slide body 2 are generally symmetrically arranged, by setting the centering adjustment component, the limit block 3 can be quickly driven to separate from the slide body 2 or move to the side close to the slide body 2, while reducing the equipment investment.

[0021] Specifically, the connecting bracket 404 includes a crossbar 4041 and a plurality of vertical rods 4042 vertically fixed to the top of the crossbar 4041 , the top of the vertical rod 4042 is fixedly connected to the limit stopper 3 , and the second connecting rod 403 is rotatably connected to the middle of the crossbar 4041 .

[0022] A plurality of limiting slide rails 101 are arranged on both sides of the top of the moving member 1 along the width direction of the moving member 1 , and the bottom ends of the two limiting blocks 3 are arranged with slide grooves matching the limiting slide rails 101 , so as to improve the movement stability of the limiting blocks 3 .

[0023] Working principle: During operation, the two limit blocks 3 are located on both sides of the top of the slide body 2, and the slide body 2 moves back and forth between the two limit blocks 3. When the slide body 2 needs to be inspected and maintained, the linear drive component 401 pushes the connecting bracket 404 and the limit block 3 on one side to move synchronously along the width direction of the moving component 1 toward the side away from the slide body 2. The connecting bracket 404 then drives the connecting bracket 404 and the limit block 3 on the other side to move in the opposite direction through the first connecting rod 402 and the second connecting rod 403, so that the distance between the two limit blocks 3 is increased, making it convenient to take out the slide body 2 for inspection and maintenance.

[0024] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
