Description

Technical Field

[0001] The utility model relates to the technical field of vertical machining centers, in particular to a protective mechanism for a vertical machining center. Background Art

[0002] A vertical machining center refers to a machining center in which the spindle axis is set vertically to the worktable. It is mainly suitable for machining complex parts such as plates, discs, molds and small shells. A vertical machining center can complete milling, boring, drilling, tapping and cutting threads. A vertical machining center is at least three-axis two-linkage, and generally can achieve three-axis three-linkage. Some can perform five-axis and six-axis control. The height of the column of a vertical machining center is limited, and the processing range of box-type workpieces should be reduced, which is a disadvantage of a vertical machining center. However, the workpiece of a vertical machining center is easy to clamp and position; the motion trajectory of the cutting tool is easy to observe, and the debugging program is easy to check and measure, so problems can be discovered in time, and shutdown processing or modification can be carried out; cooling conditions are easy to establish, and the cutting fluid can directly reach the tool and the machining surface; the three coordinate axes are consistent with the Cartesian coordinate system, and the intuitive feeling is consistent with the drawing perspective. The chips are easy to remove and fall, avoiding scratches on the processed surface.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] See also Figure 1-Figure 4 As shown, a technical solution provided by the utility model:

[0026] It includes a machining center body 1; a protective mechanism 2 is connected to the front of the machining center body 1, and the protective mechanism 2 includes a bracket 201, and the bracket 201 is connected to the top and bottom of the front of the machining center body 1.

[0027] Example 1

[0028] A vertical machining center protection mechanism, such as Figure 1-Figure 4 As shown, the protection mechanism 2 also includes a limiting tooth 206, which is connected to the inner side of the bracket 201. The bracket 201 is made of elastic material. The limiting teeth 206 are equidistantly arranged, and the limiting teeth 206 are symmetrically arranged at both ends of the inner side of the bracket 201. The protection mechanism 2 also includes a fixed groove 207, a reset spring 208 and a rotating block 209. The fixed groove 207 is opened on both sides of the front of the machining center body 1, and the two ends of the bracket 201 are arranged inside the fixed groove 207. The reset spring 208 is connected to the two ends of the bracket 201, and the rotating block 209 is connected to the end of the bracket 201. The reset spring 208 is fixedly connected to the rotating block 209. The protection mechanism 2 also includes a protection net 210 and a protection film 211. The protection net 210 is made of a metal mesh material. The protection net 210 is connected to the inner side of the protection frame 202, and the protection film 211 is arranged on the outer side of the protection net 210. The protection mechanism 2 also includes a limiting rod 212 and a limiting wheel 213. The limiting rod 212 is connected to the inner end of the fixing groove 207, and one end of the limiting rod 212 is arranged through the machining center body 1. The limiting wheel 213 is arranged at the end of the limiting rod 212. The limiting wheel 213 is rotatably connected to the limiting rod 212. The two ends of the limiting wheel 213 are connected to a rotating shaft 214, and the two ends of the rotating shaft 214 are connected to the limiting rod 212.

[0029] In this embodiment, the protective mechanism 2 can protect the machining center body 1 during use. The bracket 201 made of elastic material can facilitate the adjustment of the curvature of the bracket 201, thereby adjusting the distance between the protective structure and the machining center body 1. At the same time, the channel between the limiting teeth 206 forms an adjustment groove, which is convenient for the protective frame 202 to be adjusted inside the adjustment groove through the moving wheel 203, and the gap between the limiting teeth 206 facilitates the curvature adjustment of the bracket 201.

[0030] Example 2

[0031] like Figure 1 , 3 As shown, the adjustment mechanism 3 includes a screw 301, an adjustment cylinder 302 and a support block 303, the screw 301 is connected to the top and bottom ends inside the machining center body 1, one end of the screw 301 passes through the machining center body 1 and is arranged on the back of the machining center body 1, the adjustment cylinder 302 is sleeved on the outside of the screw 301, the end of the adjustment cylinder 302 passes through the machining center body 1 and is arranged inside the machining center body 1, the support block 303 is connected to the end of the adjustment cylinder 302, and the support block 303 is an arc structure. The adjustment mechanism 3 also includes a connecting frame 304 and an adjustment handle 305, the connecting frame 304 is connected to the inside of the machining center body 1, the screw 301 is arranged through the connecting frame 304, the connecting frame 304 is respectively connected to the middle of the screw 301 and the end of the screw 301, and the adjustment handle 305 is fixedly set at the end of the screw 301.

[0032] In this embodiment, the adjustment mechanism 3 facilitates the adjustment of the distance between the protection mechanism 2 and the machining center body 1. The adjustment cylinder 302 sleeved on the outside of the screw 301 is meshed with the screw 301. At the same time, the adjustment cylinder 302 is a non-cylindrical structure. Its own shape can be used to limit and guide the movement of the adjustment cylinder 302 to prevent the adjustment cylinder 302 from rotating with the screw 301.

[0033] When a vertical machining center protection mechanism of the utility model is in use, the screw rod 301 is rotated by the driving handle, and the screw rod 301 rotates accordingly and drives the mutually meshing adjustment cylinder 302 to move along the screw rod 301, and the support block 303 at the end of the adjustment cylinder 302 bends the middle of the abutting bracket 201 in a direction away from the machining center body 1, and the two ends of the bracket 201 move outward along the fixed groove 207 accordingly, and the return springs 208 at both ends are stretched. After the bending deformation, the angle between the bracket 201 and the machining center body 1 changes accordingly, so the gap between the bracket 201 at the end of the fixed groove 207 increases. At this time, the limiting rod 212 moves outward under the drive of the buffer spring and moves the limiting wheel 213 to the inside of the bracket 201, so as to assist in limiting the bracket 201. After the bracket 201 is bent and adjusted, the gap between the limiting teeth 206 on the inner side of the bracket 201 decreases, and the gap between the limiting teeth 206 on the outer side of the bracket 201 increases, so as to avoid deformation of the slide groove that limits the moving wheel 203. After the adjustment is completed, the channel formed between the limiting teeth 206 can facilitate the movement of the moving wheel 203 inside. The protective frame 202 moving along the bracket 201 can perform protective operations on the machining center body 1. The protective net 210 structure can protect large-volume debris and prevent debris from splashing. At the same time, the protective film 211 made of transparent material can protect small particles of debris while facilitating the operator to observe the inside. The protective structure of flexible material can facilitate the movement and adjustment of the bracket 201 along different arcs.
