Description

Technical Field

[0001] This utility model belongs to the field of engraving and milling machine tool setting technology, specifically, it relates to a fully automatic tool setting engraving and milling machine. Background Technology

[0002] A CNC engraving and milling machine is a type of CNC machine tool. It has an internal control program that enables engraving and milling in three directions: X, Y, and Z, to produce engraved and milled products. During the engraving and milling process, the cutting tools wear down over time, leading to a decrease in machining accuracy. To prevent this decrease in accuracy, current technology incorporates a tool setter within the engraving and milling machine to monitor and inspect the cutting tools.

[0003] Chinese utility model patent CN210452029U discloses a chip-prevention device for a milling machine's tool setting device, including a worktable, a Y-axis moving device, a connecting frame, an X-axis moving device, a milling cutter, a Z-axis moving device, and a mounting frame. The connecting frame is fixed to one end of the top of the worktable, and the mounting frame is fixed to the other end. An X-axis moving device is located between the connecting frame and the mounting frame, connecting to the Z-axis moving device, which in turn connects to the milling cutter. By incorporating a cavity and a blocking device, the tool setting device is prevented from being exposed on the worktable. With the aid of a push-out device, the tool setting device can be pushed out to perform a test on the milling cutter. After the test, the push-out device restores the tool setting device to its original state, while chip-blowing devices A and B clean the tool setting device, preventing contamination from coolant and metal chips. The rotating drums in chip-blowing devices A and B can rotate, thus preventing metal chips from splashing in and affecting the cleaning effect.

[0004] The existing technology has the following drawbacks: when setting the tool on the engraving and milling machine, it is necessary to manually control the tool to contact the tool setting device for tool setting. This method is slow and will produce a large error. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the problem mentioned in the background art that when setting tools on a CNC engraving and milling machine, manual control of the tool to contact the tool setting device is required, which is slow and produces significant errors, this utility model adopts the following technical solution.

[0007] A fully automatic tool-setting engraving and milling machine includes an engraving and milling assembly installed inside the machine body. A cutting tool is installed at the bottom of the engraving and milling assembly. Movable door panels are slidably connected to both sides of the machine body. A control panel is installed on the outer wall of the machine body. A material fixing plate that can move left, right, up, and down is installed on the bottom inner side of the machine body. An installation groove is provided at the center of the upper end of the material fixing plate. A tool-setting assembly is installed inside the installation groove. The tool-setting assembly can set the cutting tool.

[0008] Preferably, a connecting bracket is detachably connected to the top inner side of the engraving and milling machine body, and a tool magazine is rotatably connected to the bottom of the connecting bracket. The connecting bracket has a built-in drive motor that drives the tool magazine to rotate. A measuring component is installed on the inner wall of the engraving and milling machine body, which can detect the length of the tool on the tool magazine.

[0009] Preferably, the tool setting assembly includes an electric telescopic rod, a first rangefinder, and a mounting plate. The electric telescopic rod is detachably connected to the bottom inner side of the mounting groove, and the telescopic end of the electric telescopic rod is detachably connected to the mounting plate. The first rangefinder is detachably connected to the inner wall of the mounting groove near the top. The first rangefinder detects the upward movement distance of the mounting plate. A limit protrusion is fixedly connected to the inner wall of the mounting groove. When the bottom of the mounting plate contacts the limit protrusion, the upper end of the mounting plate is parallel to the upper end of the material fixing plate.

[0010] Preferably, a positioning component is installed on the mounting plate, which causes the electric telescopic rod to stop extending after the mounting plate contacts the tool.

[0011] Preferably, a dust removal component is installed on the mounting plate, which can blow away surrounding debris when the mounting plate moves upward.

[0012] Preferably, the positioning component includes a pressure sensor, which is embedded in the upper end of the mounting plate. When the pressure sensor generates pressure data, the electric telescopic rod stops extending.

[0013] Preferably, the dust removal assembly includes an air outlet, a connecting hose, and a delivery air pump. The outer wall of the mounting plate is provided with multiple air outlets. The bottom of the mounting plate is detachably connected to a connecting hose, which communicates with each air outlet. The connecting hose passes through the material fixing plate and the engraving and milling machine body. The outer wall of the engraving and milling machine body is detachably connected to a delivery air pump, and the air outlet end of the delivery air pump is detachably connected to the end of the connecting hose.

[0014] Preferably, the measuring component includes a second rangefinder, a third rangefinder, and an extension block. The inner wall of the engraving and milling machine is provided with a second rangefinder that is positioned vertically opposite to the inner wall. The two second rangefinders are located on the upper and lower sides of the tool magazine. A third rangefinder is provided below one side of the two second rangefinders and an extension block is provided above it. The third rangefinder is positioned opposite to the second rangefinder below it, and the extension block is positioned opposite to the second rangefinder above it.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] 1. By setting the tool setting component, the engraving and milling component is pre-positioned at the coordinates above the mounting plate and stopped. The electric telescopic rod extends so that the upper end of the mounting plate contacts the unused tool. Then, the first rangefinder detects the rising distance of the mounting plate plus the thickness of the mounting plate. The tool distance is adjusted by the tool coordinates and the rising distance of the mounting plate to obtain the tool setting data, thus achieving the purpose of automatic tool setting. After the tool wears out due to long-term use, the parameters can be adjusted by the change in the rising distance of the mounting plate, and it can also be determined whether the tool needs to be replaced.

[0017] 2. When the pressure sensor in the positioning component comes into contact with the tool, the electric telescopic rod stops extending the moment the pressure is generated, thereby enabling precise positioning of the mounting plate and making the tool setting more accurate.

[0018] 3. When the air outlet of the blowing assembly extends beyond the upper end of the material fixing plate, the electric telescopic rod stops extending. The external air is then blown out from the inside of the air outlet through the connecting hose by the air pump, which can blow away the debris on the upper end of the material fixing plate and prevent the debris from entering the installation groove and blocking the first rangefinder during the knife setting.

[0019] 4. By setting the measurement components, the position coordinates of the second and third rangefinders on both sides are determined in advance. The second rangefinders on both sides detect the distance above and below the tool on the tool magazine plate, respectively. The third rangefinder detects the distance to the protruding block. Then, the length of the tool can be obtained by subtracting the distance above and below the tool from the distance of the third rangefinder. The tool on the tool magazine plate can be automatically measured to avoid the tool being too short to be usable. Attached Figure Description

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments. The present invention provides the following embodiments.

[0031] like Figure 1The diagram shows a preferred embodiment of a fully automatic tool-setting engraving and milling machine of this utility model. This embodiment includes an engraving and milling assembly 102 installed inside the machine body 100. A tool 103 is installed at the bottom of the engraving and milling assembly 102. Movable door 101 is slidably connected to both sides of the machine body 100. A control panel 104 is installed on the outer wall of the machine body 100. A material fixing plate 200 that can move left, right, up, and down is installed on the inner bottom of the machine body 100. In this embodiment, the workpiece to be engraved and milled is fixed on the upper end of the material fixing plate 200. The workpiece is engraved and milled by coordinating the left, right, up, and down movement of the material fixing plate 200 and the forward and backward movement of the engraving and milling assembly 102. Closing the two movable door 101 on both sides prevents debris from splashing outwards during engraving and milling.

[0032] like Figure 2 As shown, this is a schematic diagram of the knife-setting assembly structure in this embodiment. A mounting groove 201 is provided at the center of the upper end of the material fixing plate 200. An electric telescopic rod 202 is detachably connected to the bottom inner side of the mounting groove 201. The telescopic end of the electric telescopic rod 202 is detachably connected to a mounting plate 204. A first rangefinder 203 is detachably connected to the inner wall of the mounting groove 201 near the upper part. The first rangefinder 203 detects the upward movement distance of the mounting plate 204. A limiting protrusion is fixedly connected to the inner wall of the mounting groove 201. When the bottom of the mounting plate 204 contacts the limiting protrusion, the upper end of the mounting plate 204 is parallel to the upper end of the material fixing plate 200. In this embodiment... The milling assembly 102 is pre-set to the coordinates above the mounting plate 204 and then stopped. The electric telescopic rod 202 extends so that the upper end of the mounting plate 204 contacts the unused tool 103. The first rangefinder 203 detects the rising distance of the mounting plate 204 plus the thickness of the mounting plate 204. The distance of the tool 103 is adjusted by the coordinates of the tool 103 and the rising distance of the mounting plate 204 to obtain tool setting data, thereby achieving the purpose of automatic tool setting. After the tool 103 wears out from long-term use, the parameters can be adjusted by the change in the rising distance of the mounting plate 204, and it can be determined whether the tool 103 needs to be replaced.

[0033] It is worth noting that the electric telescopic rod 202, the first rangefinder 203, and the mounting plate 204 mentioned above are the tool setting components in this embodiment.

[0034] like Figure 2As shown, this is a schematic diagram of the positioning component structure in this embodiment. A pressure sensor 205 is embedded in the upper end of the mounting plate 204. When the pressure sensor 205 generates pressure data, the electric telescopic rod 202 stops extending. In this embodiment, the electric telescopic rod 202 stops extending the instant the pressure sensor 205 contacts the tool 103 and generates pressure, thereby enabling precise positioning of the mounting plate 204 and making the tool setting more accurate.

[0035] It is worth noting that the pressure sensor 205 mentioned above is a positioning component in this embodiment. Positioning components include, but are not limited to, the pressure sensor 205.

[0036] like Figure 3 As shown, this is a schematic diagram of the dust removal component structure in this embodiment. The outer wall of the mounting plate 204 is provided with multiple air vents 207. A connecting hose 208 is detachably connected to the bottom of the mounting plate 204. The connecting hose 208 communicates with each air vent 207 and extends out of the material fixing plate 200 and the engraving and milling machine body 100. A conveying air pump 206 is detachably connected to the outer wall of the engraving and milling machine body 100. The air outlet of the conveying air pump 206 is detachably connected to the end of the connecting hose 208. In this embodiment, when the air vent 207 exceeds the upper end of the material fixing plate 200, the electric telescopic rod 202 stops extending.

A second rangefinder 302, positioned vertically opposite each other, is installed on the inner wall of the engraving and milling machine body 100. The two second rangefinders 302 are located on the upper and lower sides of the tool magazine 301. A third rangefinder 303 is installed below one side of each of the two second rangefinders 302, with an extension block above it. The third rangefinder 303 and the second rangefinder 302 below it are connected. With the protruding block positioned opposite the second rangefinder 302 above it, in this embodiment, the position coordinates of the second rangefinders 302 and the third rangefinder 303 on both sides are determined in advance. The second rangefinders 302 on both sides detect the distance above and below the tool 103 on the tool magazine 301, respectively. The third rangefinder 303 detects the distance to the protruding block. The length of the tool 103 can be obtained by subtracting the distance on both sides of the tool 103 from the distance of the third rangefinder 303. The tool 103 on the tool magazine 301 can be automatically measured in length to avoid it being too short to be usable.

[0039] It is worth noting that the second rangefinder 302, the third rangefinder 303 and the protruding block mentioned above are the measuring components in this embodiment.
