Detailed implementation mode

[0031] In order to further understand the features, technical means, specific purposes and functions achieved by the present invention, the present invention will be described in further detail below in conjunction with the accompanying drawings and specific implementation modes.

[0032] See Figures 1 - 6 As shown, a protective device for machining includes a fixed plate 1, a clamping seat 2 arranged on the fixed plate 1 for placing a workpiece, a threaded clamping block 3 respectively arranged on the fixed plate 1 for clamping the workpiece on the clamping seat 2, a drilling machine 4 vertically slidably arranged on the fixed plate 1 for drilling the workpiece on the clamping seat 2, an electric telescopic rod 5 arranged on the fixed plate 1 for driving the drilling machine 4 to slide vertically, and a protection and cleaning mechanism 6 vertically slidably arranged on the drilling machine 4 for covering and protecting the clamping seat 2 to prevent splashing. The protection and cleaning mechanism 6 includes a protective cover 61 and a scraper 62 for scraping and cleaning the area covered and protected by the protective cover 61.

[0033] When it is necessary to drill the workpiece on the clamping seat 2, first rotate a pair of oppositely arranged threaded clamping blocks 3 until the threaded clamping blocks 3 clamp and position the workpiece on the clamping seat 2. Then, the electric telescopic rod 5 is activated and drives the drilling machine 4 to slide downward in the vertical direction. During this process, the protective cover 61 shell follows the downward movement of the drilling machine 4 until the drilling machine 4 contacts the workpiece. During the contact between the drilling machine 4 and the workpiece, the protective cover 61 can first contact the fixed plate 1 and cover the upper part of the drilling machine 4 and the clamping seat 2 to form a protection area. When the protective cover 61 first contacts the fixed plate 1, it can drive the protective cover 61 to continue to move downward along the guide rod 63 following the drilling machine 4, and during this process, the return spring 64 is compressed inside, so that when the drilling machine 4 descends, it can drive the connected protective cover 61 to descend synchronously to form a complete protection area. When the protective cover 61 follows the drilling machine 4 to move downward in the vertical direction, it can drive the hinge rod 65 to move the connecting column 66 that is slidably arranged in the horizontal linear direction on the limiting groove 68. During this process, the connecting column 66 is in a scraping state, so as to achieve automatic scraping when the protective cover 61 follows the drilling machine 4 to descend, and when the protective cover 61 follows the drilling machine 4 to rise, it can scrape the area near the edge of the clamping seat 2 on the fixed plate 1 again through the hinge rod 65 and the scraper, so as to achieve protection during the drilling of the drilling machine 4 and also scrape and collect the waste chips generated in the processing area.

[0034] See Figures 4 - 11 As shown, the protection and cleaning mechanism 6 further includes a guide rod 63 and a return spring 64; the guide rod 63 is arranged on the fixed plate 1 and is in clearance fit with the protective cover 61; the return spring 64 is arranged on the guide rod 63 and is fixed to the guide rod 63 and the end of the fixed plate 1 to provide a return force for the movement of the protective cover 61. A first sliding chamber 631 for the guide rod 63 to slide is provided on the protective cover 61, and the first sliding chamber 631 can compress and release the return spring 64.

[0035] When the protective cover 61 follows the drilling machine 4 to synchronously move downward in the vertical direction, it can drive the protective cover 61 to slide smoothly in the vertical direction along several guide rods 63 arranged on the fixed plate 1. During the downward movement of the protective cover 61, the return spring 64 can be compressed in the first sliding chamber 631 until the protective cover 61 fits with the upper end of the fixed plate 1 and covers the working areas of the clamping seat 2 and the drilling machine 4 to form a protection area, preventing waste chips and waste gas from leaking during the drilling process of the drilling machine 4.

[0036] See Figures 5 - 10As shown, the protection and cleaning mechanism 6 includes hinge rods 65 and connecting columns 66; the hinge rods 65 are rotatably arranged on the protective cover 61 and there are a pair of them; the connecting columns 66 are arranged on the fixed plate 1 in the horizontal linear sliding direction and are rotatably connected to the hinge rods 65 to provide support and guidance when the protective cover 61 moves. A positioning plate rotatably connected to the hinge rod 65 is arranged on the protective cover 61, and the connecting column 66 is fixedly connected to the scraping plate 62.

[0037] When the protective cover 61 slides downward in the vertical direction along the guide rod 63, the hinge rod 65 rotatably installed on the positioning plate can drive the connecting column 66 and the scraping plate 62 rotatably connected to it in the horizontal linear direction.

[0038] See Figures 7 - 9 As shown, the protection and cleaning mechanism 6 further includes a limiting block 67 and a limiting groove 68; the limiting block 67 is arranged on the fixed plate 1 and is close to one side of the clamping seat 2; the limiting groove 68 is opened on the limiting block 67 and is in notch fit with the connecting column 66 to limit the horizontal sliding distance of the connecting column 66. A discharge groove 11 for waste chips to pass through is opened on the fixed plate 1, and there are two pairs of discharge grooves 11 which are respectively arranged on both sides close to the clamping seat 2. A chip collecting box 12 is arranged on the fixed plate 1 below the discharge groove 11, and the chip collecting box 12 is used for collecting the storage of the waste chips scraped by the connecting column 66.

[0039] When the hinge rod 65 drives the connecting column 66 to move, the connecting column 66 can be restricted by the limiting groove 68 opened on the limiting block 67 and slide in the horizontal linear direction. During the sliding process of the connecting column 66, the waste chips at the edge area of the clamping seat 2 can be automatically scraped off. The scraped waste chips can fall onto the chip collecting box 12 through the discharge groove 11 opened on the fixed plate 1, and can be reset along the limiting groove 68 immediately when the protective cover 61 rises with the drilling machine 4. While protecting the clamping seat 2 and the working area of the drilling machine 4, the waste chips generated during processing can be automatically scraped off, avoiding the accumulation of waste chips in the dead corner area at the edge of the clamping seat 2, and there is no need for manual cleaning and collection of waste chips in the processing area.

[0040] See Figures 7 - 9 As shown, the protection and cleaning mechanism 6 further includes a vacuum generator 69 and a waste chip collecting box 691; the vacuum generator 69 is arranged on the fixed plate 1; the waste chip collecting box 691 is arranged on the fixed plate 1, and the suction end of the waste chip collecting box 691 is communicated with the suction end of the vacuum generator 69 for collecting the waste chips generated during the drilling process. An installation groove for sliding and installing a sliding pull plate 693 is opened on the waste chip collecting box 691.

[0041] When the protective cover 61 covers above the clamping seat 2 and the drilling machine 4, and the drilling machine 4 starts to enter the working state, the vacuum generator 69 starts, and through the dust suction pipe 692 connected to the waste chip collection box 691, it can suck air in the working area of the drilling machine 4 covered by the protective cover 61. At this time, the waste chips generated at the drilling machine 4 can be sent into the waste chip collection box 691 through the dust suction pipe 692, achieving automatic collection of the processing area of the bottom drilling machine 4.

[0042] See Figure 6 and Figure 7 As shown, the protection and cleaning mechanism 6 further includes a dust suction pipe 692 and a sliding pull-out plate 693; the dust suction pipe 692 is arranged on the vacuum generator 69, and the dust suction pipe 692 is respectively arranged on the waste chip collection box 691 and the protective cover 61; the sliding pull-out plate 693 is slidably arranged in the vertical direction on the waste chip collection box 691, facilitating the cleaning of the waste chips in the waste chip collection box 691.

[0043] When the collected waste chips pass through the waste chip collection box 691, they can fall onto the sliding pull-out plate 693, and the sliding pull-out plate 693 near the suction end of the dust suction pipe 692 is made of a filter mesh material, which can block the collected waste chips and make them fall onto the sliding pull-out plate 693, and through the opening on the waste chip collection box 691 for pulling, the taking and dumping of the sliding pull-out plate 693 are achieved, further improving the collection effect of the waste chips generated during the operation of the drilling machine 4.
