Description

Technical Field

[0001] The present invention relates to the field of drilling machines, in particular to a vacuum suction cup drilling machine. Background Art

[0002] Drilling machines are widely used. A common example is the magnetic drill, a mobile electric tool that uses electromagnetic principles to attract and drill holes on steel surfaces. Its working principle is that the electromagnet at the bottom of the machine generates magnetism when energized, adsorbing it to the steel structure for a secure fixation. However, magnetic drills can only perform drilling operations on metal plates. They cannot fully utilize the drilling efficiency when drilling on flat workpieces such as aluminum, plastic, wood, floor tiles, and marble, greatly affecting the type of production operations.

[0003] In order to increase the operating range of the drilling machine, vacuum suction cup drilling machines have appeared on the market. The drilling machine can be fixed on the flat board surface by vacuuming through its fixed suction cup device, which improves the type of construction operation.

DETAILED DESCRIPTION

[0034] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0035] The present invention will be further described below with reference to the embodiments.

[0036] Example: Refer to Figures 1 to 9The vacuum suction cup drilling machine 101 includes a body 100, a drilling machine 101 is movably installed on one side of the body 100, a control system 102 is installed in the middle of the body 100, a suction cup base 200 is installed at the bottom of the body 100, and the bottom of the suction cup base 200 has a concave adsorption groove 201, and a sealing strip 202 is installed on the edge of the suction cup base 200. When the sealing strip 202 contacts the working surface, the adsorption groove 201 forms an adsorption cavity, and one end of the upper surface of the suction cup base 200 is installed with a vacuum pump 103 for evacuating the adsorption cavity, a pressure switch 104 for sensing the vacuum pressure in the adsorption cavity, and a pressure relief button 105 for relieving the pressure in the adsorption cavity, wherein the vacuum pump 103, the drilling machine 101 and the pressure switch 104 are all electrically connected to and controlled by the control system 102;

[0037] During operation, the suction cup base 200 is first placed on a flat workpiece, and the vacuum pump 103 is started by the switch on the control system 102 to start working, and the suction chamber of the suction cup base 200 is evacuated. When the vacuum pressure reaches the pressure value set by the pressure switch 104, the pressure indicator light on the control system 102 lights up, and then the drilling machine 101 switch is turned on, and the drilling machine 101 is started to start working, which plays a good role in safety protection. When the drilling is completed and needs to be shifted, just turn off the switch controlling the vacuum pump 103 and press the pressure relief button 105. The drilling machine 101 can not only carry out drilling operations on metal iron plates, but also on flat and smooth workpieces such as aluminum parts, stainless steel plates, plastics, wooden boards, floor tiles, marble, glass, etc., with better work efficiency.

[0038] Among them, there are two adsorption grooves 201, and the two adsorption grooves 201 are connected to the vacuum pump 103 through the vacuum switching mechanism 300. The vacuum switching mechanism 300 is used to control the connection status between the two adsorption grooves 201 and the vacuum pump 103, and then the corresponding adsorption groove 201 can be selected to work according to the actual surface conditions of the board, thereby improving the practicality and flexibility of the operation of the drilling machine 101.

[0039] Furthermore, a pair of slide rails 106 are installed at the side ends of the body 100, and the two slide rails 106 are respectively located on both sides of the body 100. The side of the body 100 has a movable opening 107, and the movable opening 107 is located in the middle of the two slide rails 106. A slide plate 108 that slides with the slide rail 106 is installed on the back side of the drilling machine 101, and a rack 109 that passes through the movable opening 107 and is located in the body 100 is installed on the inner side of the slide plate 108. A handle 111 is rotatably installed on the upper part of the body 100, and a gear 110 that meshes with the rack 109 is installed on the inner end of the handle 111. During drilling operations, by rotating the handle 111 clockwise or counterclockwise, since the position of the gear 110 is unchanged, the gear 110 is driven to rotate by the handle 111, and then the rack 109 can be controlled to drive the drilling machine 101 to move up and down to perform drilling operations.

[0040] Furthermore, the middle of the adsorption tank 201 has a rectangular enclosure 203, such as Figure 3 and Figure 4 As shown in the figure, the enclosure 203 divides the adsorption tank 201 into an inner tank 2011 and an outer tank 2012. The inner tank 2011 is rectangular, and the outer tank 2012 is round and surrounds the inner tank 2011. The vacuum switching mechanism 300 is installed in the outer tank 2012, and the vacuum switching mechanism 300 has a first connecting pipe 301 and a second connecting pipe 302 which are respectively connected to the inner tank 2011 and the outer tank 2012. One end of the first connecting pipe 301 passes through the enclosure 203 and extends into the inner tank 2011. A pipe is opened in the outer tank 2012 to communicate with the vacuum pump 103. The vacuum interface 303, when the vacuum pump 103 is connected to the inner groove 2011 through the first connecting pipe 301, can extract the air in the cavity formed between the inner groove 2011 and the board surface to fix the drilling machine 101. Similarly, when the vacuum pump 103 is connected to the outer groove 2012 through the second connecting pipe 302, can extract the air in the cavity formed between the outer groove 2012 and the board surface to fix the drilling machine 101. Then, when drilling the board surface, the inner groove 2011 or the outer groove 2012 can be selected as the vacuum chamber according to the actual flatness of the board surface.

[0041] The vacuum switching mechanism 300 includes a sphere 307 that is rotatably mounted in the outer groove 2012 along a horizontal direction. The outer groove 2012 has a spherical cavity for mounting the sphere 307. The bottom of the spherical cavity is connected to the vacuum interface 303 through a vacuum channel 308. A lower connecting channel 3071 that connects to the vacuum channel 308 is vertically opened in the middle of the bottom end of the sphere 307. A first channel 3072 and a second channel 3073 are horizontally opened in the middle of the sphere 307. The first channel 3072 and the second channel 3073 are connected to the lower connecting channel 3071, forming a "T" shape as a whole. The first connecting pipe 301 and the second connecting pipe 302 are arranged vertically and are located in the same horizontal plane as the first channel 3072 and the second channel 3073.

[0042] During drilling operation, by rotating the sphere 307 90° clockwise or counterclockwise, the first channel 3072 can be connected to the second connecting pipe 302 (the second channel 3073 is staggered with the first connecting pipe 301 and is blocked by the inner wall of the spherical cavity, as shown in FIG. Figure 7 As shown in ), the vacuum pump 103 can extract the air in the outer tank 2012 through the channel formed by the vacuum channel 308, the lower connecting channel 3071, the first channel 3072 and the second connecting pipe 302, or connect the second channel 3073 to the first connecting pipe 301 (the first channel 3072 and the second connecting pipe 302 are staggered and blocked by the inner wall of the spherical cavity, as shown in Figure 8 As shown in FIG, the vacuum pump 103 can extract the air in the inner tank 2011 to realize the selective switching of the inner tank 2011 or the outer tank 2012.

[0043] Furthermore, a third channel 3074 is provided in the middle of the sphere 307, which is connected to the first channel 3072, the second channel 3073 and the lower connecting channel 3071. The third channel 3074 is arranged vertically to the first channel 3072 and the second channel 3073.

[0044] As can be seen from the above-mentioned first channel 3072 and the second channel 3073 being arranged linearly, and the first connecting pipe 301 and the second connecting pipe 302 being arranged vertically, there is only a situation where the first channel 3072 is connected to the second connecting pipe 302 or the second channel 3073 is connected to the first connecting pipe 301. Considering that in actual working process, the entire plate surface is relatively flat, but the plate surface is thick as a whole, and the drilling work intensity is relatively high, a third channel 3074 is provided, and the vacuum pump 103 can be connected to the inner tank 2011 and the outer tank 2012 at the same time through the third channel 3074 (such as Figure 9 ), thereby increasing the volume of the vacuumed inner cavity and improving the fixing effect of the drilling machine 101.

[0045] Furthermore, the outer groove 2012 has a cylindrical hollow mounting portion 2013, which is in the shape of a hollow column. A lower base 309 and an upper fixing seat 310 are installed in the mounting portion 2013. The vacuum channel 308 is located in the middle of the lower base 309 and is connected to the vacuum interface 303. The docking end of the lower base 309 and the upper fixing seat 310 has a hemispherical groove 311 and a connecting groove 312 corresponding to the first connecting tube 301 and the second connecting tube 302. The first connecting tube 301 and the second connecting tube 302 have a sealing protrusion 314 at the end of the connecting groove 312, and a sealing groove corresponding to the sealing protrusion 314 is opened on the groove wall in the middle of the connecting groove 312. 315, convenient for assembling the sphere 307 and the first connecting tube 301 and the second connecting tube 302, wherein the top of the sphere 307 has a control rod 3075 passing through the middle of the upper fixing seat 310, and the middle of the upper fixing seat 310 has a hole for the control rod 3075 to pass through. A locking cover 313 for limiting the control rod 3075 is installed on the upper fixing seat 310, and the end of the control rod 3075 has a regular polygonal control groove. The rotation angle of the sphere 307 is rotated by an external operating rod adapted to the control groove to achieve the control of the connection state between the first channel 3072, the second channel 3073 and the third channel 3074 and the first connecting tube 301 and the second connecting tube 302.

[0046] Furthermore, auxiliary pressure relief ports 304 are provided in both the inner tank 2011 and the outer tank 2012, and a main pressure relief port 305 is provided on the upper portion of the suction cup base 200. The two auxiliary pressure relief ports 304 are respectively connected to the main pressure relief port 305 (i.e., the two auxiliary pressure relief ports 304 are two branches of the main pressure relief port 305, not shown in the figure), and the pressure relief button 105 is installed at the main pressure relief port 305. That is, regardless of whether the inner tank 2011 or the outer tank 2012 is used as the working chamber, the corresponding pressure can be relieved through the pressure relief button 105. Auxiliary pressure detection ports 306 are provided in both the inner groove 2011 and the outer groove 2012, and a main pressure detection port is provided on the upper part of the suction cup base 200. The two auxiliary pressure detection ports 306 are respectively connected to the main pressure detection port (similar to the two auxiliary pressure relief ports 304 being respectively connected to the main pressure relief port 305, not shown in the figure), and the pressure switch 104 is installed at the main pressure detection port. Similarly, the vacuum pressure when the inner groove 2011 or the outer groove 2012 is evacuated can be detected through the pressure switch 104 to facilitate subsequent drilling work.

[0047] Furthermore, mounting grooves 204 are provided at the bottom of the outer edges of the enclosure 203 and the adsorption groove 201, and two sealing strips 202 are provided and adapted to the corresponding mounting grooves 204. The outer ends of the sealing strips 202 protrude from the mounting grooves 204, facilitating precise contact with the panel surface.
