Description

Technical Field

[0001] The utility model relates to the technical field of aluminum alloy milling, in particular to a splash preventer for an aluminum alloy milling cutter. Background Art

[0002] When cutting metal parts, a large amount of flying chips will be generated. These flying chips often splash onto the operator, causing harm to the operator's body. The existing protective device installed on the tool part only installs a baffle above the tool part to shield the flying chips. In actual use, it can only block the flying chips above the tool part, and the flying chips in other directions of the tool part cannot be blocked. In addition, the baffle may become loose and slide off, which reduces the protectiveness and may increase the harm to the operator. Therefore, there is an urgent need for a tool part that can fully prevent flying chips from splashing to protect the operator from being injured. Utility Model Content

[0003] The utility model aims to provide an aluminum alloy milling cutter splash guard, which is used to overcome the above-mentioned defects in the prior art.

[0004] According to the utility model, an aluminum alloy milling cutter splash preventer comprises a tool seat, a detachable milling cutter is fixedly arranged at the lower end of the tool seat, four sliding cavities uniformly distributed in the circumference are opened on the outer circumference of the tool seat, a steel cylinder capable of sliding up and down is arranged on the outer circumference of the tool seat, a protective cylinder is fixedly arranged at the lower end of the steel cylinder, a storage cavity corresponding to the sliding cavity is opened on the inner circumference of the steel cylinder, a pressure block is slidably connected in each of the storage cavities, a thrust spring is connected between the storage cavity and the pressure block, the pressure block extends inwardly and abuts against the sliding cavity, a push plate is slidably connected in each of the sliding cavities, a push spring is connected between the sliding cavity and the push plate, the upper end of the pressure block abuts against the push plate, an abutment plate uniformly distributed in the circumference of the steel cylinder is hinged, the abutment plate is located in the sliding cavity, uniformly distributed opening grooves are opened on the outer circumference of the protective cylinder, a collection box is fixedly arranged on the outer circumference of the protective cylinder, and a collection pipe is connected at the upper end of the collection box.

[0005] The beneficial effects of the utility model are:

[0006] By arranging four circumferentially evenly distributed pressure blocks between the steel cylinder and the tool seat and connecting thrust springs at the pressure blocks, the steel cylinder can be fitted onto the outer circumference of the tool seat to prevent the steel cylinder from falling and improve the stability of the steel cylinder. The protective cylinder at the lower end of the steel cylinder can shield the debris generated during the working process and improve the safety of the milling cutter during use. The debris is absorbed by air extraction through the collecting pipe to further prevent the debris from splashing and make the milling surface clean. During the replacement of the milling cutter, the abutment plate abuts against the push plate to prevent the push plate from excessively descending and causing the subsequent pressure block and push plate to be stuck.

Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0017] It should be noted that when an element is said to be "fixed to" another element, it can be directly on the other element or there can be an intermediate element. When an element is said to be "connected to" another element, it can be directly connected to the other element or there can be an intermediate element at the same time:

[0018] Embodiment 1:

[0019] Reference Figure 1-Figure 7 According to an embodiment of the utility model, an aluminum alloy milling cutter splash guard comprises a cutter seat 10, a detachable milling cutter 11 is fixedly arranged at the lower end of the cutter seat 10, four sliding cavities 17 evenly distributed in the circumference are opened on the outer periphery of the cutter seat 10, a steel cylinder 12 capable of sliding up and down is arranged on the outer periphery of the cutter seat 10, a protective cylinder 13 is fixedly arranged at the lower end of the steel cylinder 12, a receiving cavity 19 corresponding to the sliding cavity 17 is opened on the inner periphery of the steel cylinder 12, and a pressure block 21 is slidably connected in each receiving cavity 19, and a pressure block 21 is provided between the receiving cavity 19 and the pressure block 21. A thrust spring 20 is connected, a pressure block 21 extends inwardly and abuts against the sliding cavity 17, a push plate 22 is slidably connected in each sliding cavity 17, a push spring 18 is connected between the sliding cavity 17 and the push plate 22, the upper end of the pressure block 21 abuts against the push plate 22, an abutment plate 23 evenly distributed in the circumference is hinged on the outer periphery of the steel cylinder 12, the abutment plate 23 is located in the sliding cavity 17, and an evenly distributed opening groove 16 is opened on the outer periphery of the protection cylinder 13, a collection box 14 is fixed on the outer periphery of the protection cylinder 13, and a collection pipe 15 is connected to the upper end of the collection box 14;

[0020] The milling cutter 11 is installed at the lower end of the tool seat 10, and the steel cylinder 12 is inserted from bottom to top into the outer peripheral part of the tool seat 10. The pressure block 21 on the steel cylinder 12 is abutted against the peripheral surface of the tool seat 10, pushing the abutment plate 23 to swing upward and abut against the peripheral surface of the pressure block 21, overcoming the spring force of the thrust spring 20 to extend and retract into the storage cavity 19, pushing the steel cylinder 12 upward, so that the steel cylinder 12 is positioned as a whole on the outer peripheral part of the tool seat 10, protecting the steel cylinder 13 as a whole. At this time, the pressure block 21 is partially located on the peripheral side of the sliding cavity 17, and the steel cylinder 12 is rotated circumferentially to align the pressure block 21 on the steel cylinder 12 with the sliding cavity 17. The pressure block 21 slides toward the tool seat 10 under the spring thrust of the thrust spring 20, pushing the abutment plate 23 to swing downward through the hinge rod, and the pressure block 21 abuts against the peripheral side wall of the sliding cavity 17. Figure 7 As shown, the lower end of the milling cutter 11 abuts against the aluminum alloy plate to perform milling. During the milling process, the protective tube 13 can abut against the plate. As the milling depth of the milling cutter 11 changes, the spring force of the push spring 18 that the protective tube 13 needs to overcome changes accordingly. The debris generated during the milling process of the milling cutter 11 enters the collection box 14 through the opening groove 16. Air is extracted from the collection box 14 to form a low-pressure environment. At the same time, the debris in the collection box 14 is absorbed by the collection pipe 15, and the debris is shielded by the protective tube 13 to prevent the debris from splashing.

[0021] The steel cylinder 12 is pushed upward, and the pressure block 21 simultaneously pushes the push plate 22 upward. The spring force of the push spring 18 on the push plate 22 gradually increases until the pressure block 21 moves to the upper end of the sliding cavity 17. The fillet between the push plate 22 and the pressure block 21 allows the pressure block 21 to overcome the spring force of the thrust spring 20 and slide into the storage cavity 19. The steel cylinder 12 is clamped on the tool seat 10, and the pressure block 21 abuts against the push plate 22 to prevent the push plate 22 from sliding downward excessively. The protective cylinder 13 is located on the tool seat 10, and the milling cutter 11 is disassembled and replaced at the lower end of the tool seat 10.

[0022] It is clear to those skilled in the art that various modifications to the above embodiments can be made without departing from the overall spirit and concept of the present invention. All of them fall within the protection scope of the present invention. The protection scheme of the present invention shall be subject to the claims attached to the present invention.
