[0002] A vertical lift table milling machine is a general-purpose metal-cutting machine with a worktable that can be raised and lowered vertically and moved horizontally. This machine is primarily used for machining flat surfaces, bevels, grooves, and holes. Equipped with a variety of milling cutters, such as cylindrical milling cutters, face milling cutters, and form milling cutters, it can produce a wide variety of complex parts. Its stable structure and excellent rigidity make it suitable for industries such as machinery manufacturing, molds, automotive, and aerospace, meeting the machining needs of parts of varying sizes and shapes.

[0003] Milling machines generate metal chips during operation. These chips can fly onto the operator's body or eyes due to centrifugal force or airflow during high-speed cutting, potentially causing injury. To prevent this potential danger, milling machines require protective devices, such as shields or screens, to block the flying metal chips and protect the operator from potential bodily harm.

[0004] Currently, commonly used safety guards on the market rely primarily on bolted, threaded connections or direct clamping onto the workbench. However, the former is time-consuming and labor-intensive to disassemble and maintain, inevitably reducing work efficiency. The latter, on the other hand, can become detached during operation due to factors like milling machine vibrations and the impact of metal chips, posing a threat to worker safety. Therefore, these protection methods have certain limitations.

[0005] Currently, no effective solutions have been proposed for the problems in related technologies. Utility Model Content

Figure 1-Figure 7 As shown, the safety protection structure for a vertical lifting platform milling machine according to an embodiment of the present invention includes a clamping groove 3 symmetrically arranged on the top of the workbench 2, and the workbench 2 is located on one side of the vertical lifting platform milling machine 1, and a limiting groove 4 symmetrically arranged on both longitudinal sides of the workbench 2; safety protection plates 5 that cooperate with the limiting groove 4 are symmetrically arranged on both lateral sides of the workbench 2, and the sides where the two groups of safety protection plates 5 are close to each other are each provided with a clamping part 6 that cooperates with the clamping groove 3, and the sides where the two groups of clamping parts 6 are away from each other are each provided with a connecting component 7 that cooperates with the workbench 2 and the safety protection plate 5; limiting protrusions 8 that cooperate with the limiting groove 4 are symmetrically arranged on both longitudinal sides of the safety protection plate 5, and the shapes of the limiting protrusions 8 and the limiting groove 4 are both convex; limiting grooves 9 are symmetrically arranged on the sides where the two groups of safety protection plates 5 are close to each other, and the shape of the limiting grooves 9 is an isosceles trapezoid.

[0027] With the help of the above technical solution, the utility model, with the cooperation of the workbench 2, the safety protection plate 5, the clamping part 6 and the connecting assembly 7, can avoid the operator from being physically injured due to the splashing of metal chips during the operation of the vertical lifting platform milling machine 1, thereby protecting the safety of the operator and avoiding physical injuries caused by the splashing of metal chips; with the cooperation of the clamping part 6 and the connecting assembly 7, the safety protection plate 5 can be disassembled and maintained more conveniently while ensuring the effectiveness of protection, thereby reducing the burden on manpower and improving work efficiency.

[0028] In one embodiment, for the above-mentioned clamping member 6, the clamping member 6 includes a clamping block 601 arranged at the top of the clamping groove 1 3, and a limiting protrusion 2 602 that cooperates with the limiting groove 2 9 is symmetrically arranged on the side of the clamping block 601 close to the safety protection plate 5, and a handle 1 603 is arranged on the top of the clamping block 601; a clamping groove 2 604 is opened on the side of the bottom end of the clamping block 601 close to the safety protection plate 5, and a clamping groove 3 605 that cooperates with the clamping block 601 is arranged on the top of the clamping groove 2 604; the shape of the limiting protrusion 2 602 is an isosceles trapezoid; thereby ensuring the stability of the safety protection structure.

[0029] In one embodiment, for the above-mentioned connecting component 7, the connecting component 7 includes a limiting slider 701 arranged on one side of the clamping groove three 605 and cooperating with the workbench 2, and a connecting rod 702 is symmetrically arranged on the other side of the limiting slider 701, and the other side of the two sets of connecting rods 702 is provided with a handle 2 703 cooperating with the safety protection plate 5, and the outer side of the connecting rod 702 is provided with a spring 704 cooperating with the limiting slider 701 and the safety protection plate 5; the cross-sections of the clamping groove two 604, the clamping groove three 605 and the limiting slider 701 are all inclined surfaces with the same inclination angle; thereby, the safety protection plate 5 can be disassembled and maintained more conveniently.

[0030] The working principle of the clamping member 6 and the connecting assembly 7 is as follows:

[0031] When the safety guard plate 5 needs to be disassembled and maintained, first hold the handle 703 of the connecting assembly 7, and then pull the handle 703 in the direction away from the workbench 2, so that the handle 703 moves horizontally. Under the action of the horizontal movement of the handle 703, the connecting rod 702 moves. Under the action of the movement of the connecting rod 702, the spring 704 is squeezed, and the limit slide 701 moves, so that the limit slide 701 disengages from the locking groove 3 605. At this time, hold the handle 603 in the clamping member 6, and then pull the handle 603 in the vertical direction, driving the clamping block 601 to rise vertically under the cooperation of the limiting protrusion 602 and the limiting groove 9, so that the clamping block 601 separates from the clamping groove 3. At this time, the safety guard plate 5 can be separated from the workbench 2 under the cooperation of the limiting groove 4 and the limiting protrusion 8, and the safety guard plate 5 can be disassembled;

[0032] When it is necessary to install the safety guard plate 5, the safety guard plate 5 is first moved to the position where the workbench 2 is completely in contact with the inner side of the safety guard plate 5 under the cooperation of the limit groove 1 4 and the limit protrusion 1 8. At this time, the clamping block 601 is lowered vertically under the cooperation of the limit protrusion 2 602 and the limit groove 2 9 until the clamping block 601 contacts the clamping groove 1 3, and the clamping groove 2 604 contacts the limit slider 701. At this time, it continues to descend. Under the action of the inclined surface shape, the clamping groove 2 604 squeezes the limit slider 701 horizontally and squeezes the spring 704. When the clamping groove 2 604 is disengaged from the limit slider 701, under the reset action of the spring 704, the limit slider 701 is driven to move to the recovery starting position. At the same time, the limit slider 701 contacts the clamping groove 3 605, and the clamping block 601 contacts the inner bottom end of the clamping groove 1 3, completing the installation and fixation of the safety guard plate 5.

[0033] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in actual process is described in detail below.

[0034] In practical applications, such as Figure 1-Figure 3 and Figure 4-Figure 7 (Specific application diagram of the safety protection structure in practice), when it is necessary to use the vertical lifting table milling machine 1 for processing operations, first install the safety protection plate 5 on both sides of the workbench 2 through the limiting protrusion 8 along the limiting groove 4, and fix the safety protection plate 5 through the cooperation of the clamping part 6 and the connecting component 7 to achieve protection against metal chips generated during the operation of the vertical lifting table milling machine 1. When it is necessary to disassemble and maintain the safety protection plate 5, the safety protection plate 5 is contacted and fixed through the cooperation of the clamping part 6 and the connecting component 7, so that the safety protection plate 5 is detached from the workbench 2 through the limiting protrusion 8 along the limiting groove 4.

[0035] The working principles of the clamping member 6 and the connecting assembly 7 are as described above.

[0036] To sum up, with the help of the above-mentioned technical scheme of the present invention, the present invention can avoid the operator from being injured by metal chips flying during the operation of the vertical lifting platform milling machine 1 with the cooperation of the workbench 2, the safety protection plate 5, the clamping part 6 and the connecting assembly 7, thereby protecting the safety of the operator and avoiding physical injuries caused by metal chips flying; with the cooperation of the clamping part 6 and the connecting assembly 7, the safety protection plate 5 can be disassembled and maintained more conveniently while ensuring the effectiveness of protection, thereby reducing the burden on manpower and improving work efficiency.
