Description

Technical Field

[0001] This utility model relates to a protective mechanism, specifically a protective mechanism for a vertical machining center, belonging to the field of CNC machine tool technology. Background Technology

[0002] A vertical machining center is a machining equipment equipped with a vertical spindle. It typically employs a fixed column structure, has a rectangular worktable, and lacks indexing rotation capabilities. It is primarily used for machining discs, sleeves, and sheet metal parts. This equipment generally features three linear motion axes and can machine helical shapes by mounting a rotary table on the worktable.

[0003] When a machining center operates at high speed, the chips that fly out during part processing, the coolant splashed out by the high-speed rotating tools, and the tools that break or are broken off by the workpiece can all pose certain dangers to the operator. To ensure the safety of the operator, machining centers are often equipped with protective mechanisms at the front of the machine housing.

[0004] Chinese Patent Publication CN219026813U discloses a protective mechanism for a vertical machining center. This protective mechanism provides double protection for the machine tool through the installation of explosion-proof glass. The internal explosion-proof glass can be removed for flexible use and has low limitations on usage scenarios. The protective mechanism is installed outside the machining center and connected to it, which can reduce the space occupied compared to external protection.

[0005] In practical applications, it has been found that while the aforementioned patent provides dual protection through explosion-proof glass, the glass is easily affected by contaminants because it is located on the side closest to the processing area. This makes it difficult for operators to observe the processing situation, and the contaminants on the explosion-proof glass are difficult to clean during processing. Therefore, a protective mechanism for vertical machining centers is proposed here. Utility Model Content

[0006] This utility model proposes a protective mechanism for a vertical machining center, which can clean contaminants on explosion-proof glass without stopping the equipment, thereby improving the visibility and ease of cleaning of the explosion-proof glass.

[0007] This utility model is achieved through the following technical solution: a protective mechanism for a vertical machining center, including a guide assembly, the guide assembly including a fixed block, the fixed block being installed on the vertical machining center, a guide rod being fixed on the fixed block, a guide block being slidably connected to the guide rod, the guide block being fixed to a first protective frame, and buffer blocks being fixed at both ends of the fixed block, the outer contour of the buffer block being a cuboid.

[0008] The guide component is provided with a double-layer protective component, which includes a first protective frame and a groove in the horizontal direction.

[0009] The double-layer protective assembly also includes a second protective frame. Both the first and second protective frames are equipped with explosion-proof glass. A first slider is fixed on the second protective frame. The first slider is slidably connected to the first protective frame through a sliding groove. A cleaning rod is fixed to the right end of the second protective frame. The cleaning rod is in slidable contact with the first protective frame. A second slider is fixed to the left end of the cleaning rod. The second slider is slidably connected to the cleaning rod through a sliding groove.

[0010] A cleaning component is provided at the left end of the cleaning rod. The cleaning component includes a cleaning sponge and a fixing bolt. The cleaning sponge is fixed to the left end of the cleaning rod by the fixing bolt, and the cleaning sponge is in contact with the explosion-proof glass on the first protective frame.

[0011] An adjustment assembly is provided on the first and second protective frames. The adjustment assembly includes a slide rod, which is slidably connected to the first protective frame and the slide groove. A handle is fixed on the slide rod, and a tension spring is fixed between the handle and the second protective frame. The tension spring is sleeved on the slide rod.

[0024] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0025] Please see Figures 1-5 The present invention proposes the following implementation scheme: a protective mechanism for a vertical machining center, including a guide component 1, the guide component 1 including a fixing block 101, the fixing block 101 being installed on the vertical machining center, a guide rod 102 being fixed on the fixing block 101, a guide block 103 being slidably connected to the guide rod 102, the guide block 103 being fixed to a first protective frame 201, and the guide block 103 sliding on the fixing block 101 under the drive of the first protective frame 201.

[0026] The fixed block 101 has buffer blocks 104 fixed at both ends. The outer contour of the buffer block 104 is a cuboid. The buffer block 104 can play a buffering role and prevent the guide block 103 from directly hitting the fixed block 101.

[0027] Please refer to this carefully. Figure 2 , Figure 3 , Figure 4 and Figure 5 The guide component 1 is provided with a double-layer protective component 2, which includes a first protective frame 201 and a groove 202 in the horizontal direction.

[0028] The double-layer protective assembly 2 also includes a second protective frame 203. Both the first protective frame 201 and the second protective frame 203 are equipped with explosion-proof glass. A first slider 204 is fixed on the second protective frame 203. The first slider 204 is slidably connected to the first protective frame 201 through a slide groove 202. The first slider 204 can slide in the slide groove 202.

[0029] A cleaning rod 205 is fixed to the right end of the second protective frame 203. When the second protective frame 203 slides, it will also drive the cleaning rod 205 to slide. The cleaning rod 205 slides in contact with the first protective frame 201. A second slider 206 is fixed to the left end of the cleaning rod 205. The second slider 206 is slidably connected to the cleaning rod 205 through the slide groove 202.

[0030] Please refer to this carefully. Figure 4 and Figure 5 A cleaning component 207 is provided at the left end of the cleaning rod 205. The cleaning component 207 includes a cleaning sponge 2071 and a fixing bolt 2072. The cleaning sponge 2071 is fixed to the left end of the cleaning rod 205 by the fixing bolt 2072. The cleaning sponge 2071 is in contact with the explosion-proof glass on the first protective frame 201. After the fixing bolt 2072 is removed, the cleaning sponge 2071 can be removed and then cleaned.

[0031] An adjustment component 208 is provided on the first protective frame 201 and the second protective frame 203. The adjustment component 208 includes a slide rod 2081, which is slidably connected to the first protective frame 201 and the slide groove 202. A handle 2082 is fixed on the slide rod 2081, and a tension spring 2083 is fixed between the handle 2082 and the second protective frame 203. The tension spring 2083 is sleeved on the slide rod 2081.

[0032] Specifically, under normal conditions, the slide bar 2081 is inserted into the first protective frame 201 and the second protective frame 203. At this time, pulling the handle 2082 will simultaneously move the first protective frame 201 and the second protective frame 203, thereby opening the processing area of ​​the vertical machining center.

[0033] When the explosion-proof glass of the first protective frame 201 needs to be cleaned, pull the handle 2082 so that the handle 2082 is disengaged from the first protective frame 201. At this time, move the handle 2082 to the right. The handle 2082 will only move the second protective frame 203, while the first protective frame 201 remains in place. The movement of the second protective frame 203 will also move the cleaning rod 205, the cleaning sponge 2071, and the fixing bolt 2072. Then, the moving cleaning sponge 2071 will clean the explosion-proof glass on the first protective frame 201.

[0034] Furthermore, the friction between the guide block 103 and the fixed block 101 is greater than the friction between the second protective frame 203, the cleaning rod 205, and the cleaning sponge 2071 on the first protective frame 201, thus preventing the first protective frame 201 from moving simultaneously under the action of friction.

[0035] Working principle: The central protective mechanism achieves double-layer protection through the explosion-proof glass on the first protective frame 201 and the second protective frame 203. When contaminants appear on the explosion-proof glass on the first protective frame 201, pull the handle 2082 so that the handle 2082 only contacts the second protective frame 203. At this time, slide the second protective frame 203 to the right. The second protective frame 203 will drive the cleaning rod 205 and the cleaning sponge 2071 to clean the explosion-proof glass on the first protective frame 201. This device can clean the contaminants on the explosion-proof glass of the first protective frame 201 without stopping the equipment, improving the visibility and cleaning convenience of the explosion-proof glass.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
