Description

Technical Field

[0001] This utility model relates to the field of CNC machining technology, specifically to a tool anti-vibration auxiliary bracket for CNC machining. Background Technology

[0002] CNC machining, also known as computer-controlled milling, CNC machine tool, or numerical control machining, is a precision machining technology that uses computer digital control. The main equipment includes machining lathes, milling machines, boring and milling machines, etc., and it is characterized by stable machining quality and high precision.

[0003] In the existing technology, during CNC machining, the tool and the machine tool must first be assembled. Then, the tool rotation is controlled by numerical control programming of the machine tool so that the tool can process the material.

[0004] There are still some shortcomings in the existing technology. The existing CNC machining equipment does not have a structure to support the tool. During the CNC machining process, the tool is not securely fixed, which can cause vibration during the material processing, thus affecting the accuracy of the material processing. To this end, we propose a tool vibration prevention auxiliary bracket for CNC machining. Utility Model Content

[0005] The purpose of this invention is to provide a tool anti-vibration auxiliary bracket for CNC machining, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a tool anti-vibration auxiliary bracket for CNC machining, including a mounting plate;

[0007] The cutter body is positioned above the mounting plate;

[0008] The mounting plate includes a fixing assembly on its top. The fixing assembly comprises a mounting bracket fixedly connected to the top left side of the mounting plate. A drive motor is fixedly connected to the inner top wall of the mounting bracket. An output shaft is fixedly connected to the output end of the drive motor. A rotating seat is fixedly connected to the other end of the output shaft. Five rectangular slots are provided on the other side of the rotating seat. A forward / reverse motor is fixedly connected to the inner left side of the rotating seat. A rotating shaft is fixedly connected to the output end of the forward / reverse motor. A disc is fixedly connected to the outer wall of the other end of the rotating shaft. Five arc-shaped slots are provided on the inner wall of the disc. Five sliding rods are slidably connected to the inner walls of the five arc-shaped slots, with one end of each sliding rod sliding against the inner wall of the rotating seat. The slide rod is connected in a sliding manner. The outer wall of the other end of the slide rod is slidably connected to the inner wall of the rectangular groove. A clamping block is fixedly connected to the other end of the slide rod. The side wall of the clamping block is slidably connected to the outer wall of one end of the tool body. One end of the tool body is slidably connected to the side wall of the rotating seat. By setting a fixing component, after the disc rotates, the slide rod is pressed by the internal arc groove, which causes the slide rod to move along the inner wall of the rotating seat and drive the slide rod to move linearly along the inside of the rectangular groove. This drives the clamping block to move until all five clamping blocks press against the outer wall of the end face of the tool body. This achieves clamping and fixing of the end face of the tool body, thereby preventing the tool from vibrating during rotation and affecting the machining accuracy.

[0009] Preferably, the top of the mounting plate is further provided with an auxiliary component. The auxiliary component includes a rectangular frame fixedly connected to the top center of the mounting plate. A fixing post is fixedly connected to the top inner wall of the rectangular frame. A first clamping block and a second clamping block are slidably connected to the outer center of the fixing post. The inner center of the first clamping block is slidably connected to the outer center of the tool body. A spring is fixedly connected to the top of the first clamping block. The other end of the spring is fixedly connected to the top inner wall of the rectangular frame. By setting the auxiliary component, the tool body needs to be supported before it is fixed. The operator presses the first and second clamping blocks to both sides, causing them to move along the outer wall of the fixing post and compress the spring. Then, the operator places the tool body in the middle of the rectangular frame and releases the first and second clamping blocks. Under the reaction of the spring, the first and second clamping blocks will reset, enabling them to provide auxiliary support to the outer wall of the tool body, further improving the stability of the tool body during rotation.

[0010] Preferably, four handles are fixedly connected to the top of the four corners of the first clamping block, and the outer wall of the first clamping block is slidably connected to the inner wall of the rectangular frame. The handles make it easy for the operator to pull the first clamping block and the second clamping block.

[0011] Preferably, the first clamping block and the second clamping block have the same shape and size, and the first clamping block and the second clamping block are symmetrically distributed up and down along the central plane of the tool body. When the first clamping block and the second clamping block clamp the tool body, they can provide auxiliary support for the tool body and improve the stability of the tool body during the metal material processing.

[0012] Preferably, the bottom of the mounting plate is fixedly connected with four support legs. The four support legs are equidistantly fixed at the four corners of the bottom of the mounting plate, so that the mounting plate can be stably supported by the four support legs at the bottom of the mounting plate.

[0013] Preferably, there are five clamping blocks, and all five clamping blocks are slidably connected to the outer wall of one end of the tool body.

[0014] This invention provides a tool anti-vibration auxiliary bracket for CNC machining. This tool anti-vibration auxiliary bracket for CNC machining has the following beneficial effects:

[0015] (1) The CNC machining tool anti-vibration auxiliary bracket, by setting a fixed component, in order to improve the stability of the tool body in the process of machining metal materials during CNC machining, the tool body first needs to be installed and fixed. The operator puts the end face of the tool body against the side wall of the rotating seat, and then starts the forward and reverse motor to make the rotating shaft rotate. During the rotation of the rotating shaft, the disc will be driven to rotate. After the disc rotates, the sliding rod will be pressed by the internal arc groove, which will cause the sliding rod to move along the inner wall of the rotating seat and drive the sliding rod to move in a straight line along the inside of the rectangular groove, and drive the clamping block to move until all five clamping blocks press against the outer wall of the end face of the tool body, thereby achieving clamping and fixing of the end face of the tool body, thus avoiding the tool from vibrating during rotation and affecting the machining accuracy. After the tool body is installed, the operator starts the drive motor to make the output shaft rotate. During the rotation of the output shaft, the rotating seat and the tool body will rotate, and the metal material can be machined during the rotation of the tool body.

[0016] (2) The CNC machining tool anti-vibration auxiliary bracket, by setting auxiliary components, firstly needs to provide auxiliary support for the tool body before fixing it. The operator presses the first clamping block and the second clamping block to both sides, so that the first clamping block and the second clamping block move along the outer wall of the fixed column and compress the spring. Then, the operator places the tool body in the middle of the rectangular frame and releases the first clamping block and the second clamping block. Under the reaction of the spring, the first clamping block and the second clamping block will be reset, so that the first clamping block and the second clamping block can provide auxiliary support for the outer wall of the tool body, further improving the stability of the tool body during rotation.

[0023] To provide a clearer understanding of the technical features, objectives, and effects of this utility model, the specific embodiments of this utility model are now described with reference to the accompanying drawings.

[0024] like Figure 1-5 As shown, this utility model has the following two specific embodiments.

[0025] Example 1

[0026] A tool anti-vibration auxiliary bracket for CNC machining includes a mounting plate 1;

[0027] The cutter body 3 is positioned above the mounting plate 1;

[0028] The mounting plate 1 is equipped with a fixing assembly 41. The fixing assembly 41 includes a fixing bracket 411 fixedly connected to the top left side of the mounting plate 1. A drive motor 412 is fixedly connected to the inner wall of the top of the fixing bracket 411. An output shaft 413 is fixedly connected to the output end of the drive motor 412. A rotating seat 414 is fixedly connected to the other end of the output shaft 413. Five rectangular slots 415 are provided on the other side of the rotating seat 414. A forward and reverse motor 416 is fixedly connected to the inner wall of the left side of the rotating seat 414. A rotating shaft 417 is fixedly connected to the output end of the forward and reverse motor 416. The outer wall of the other end of the rotating shaft 417 is fixedly connected to... A disc 418 is attached, and five arc-shaped grooves 419 are formed on the inner wall of the disc 418. Five sliding rods 4110 are slidably connected to the inner walls of the five arc-shaped grooves 419 respectively. One end of each sliding rod 4110 is slidably connected to the inner wall of the rotating seat 414, and the outer wall of the other end of each sliding rod 4110 is slidably connected to the inner wall of a rectangular groove 415. A clamping block 4111 is fixedly connected to the other end of each sliding rod 4110. The side wall of the clamping block 4111 is slidably connected to the outer wall of one end of the tool body 3, and one end of the tool body 3 is slidably connected to the side wall of the rotating seat 414. By setting the fixing component 41, in order to achieve the desired performance during CNC machining... To improve the stability of the tool body 3 during the machining of metal materials, the tool body 3 first needs to be installed and fixed. The operator aligns the end face of the tool body 3 with the side wall of the rotating seat 414, and then starts the forward and reverse motor 416 to cause the rotating shaft 417 to rotate. During the rotation of the rotating shaft 417, the disc 418 will rotate. After the disc 418 rotates, the sliding rod 4110 will be pressed by the internal arc groove 419, causing the sliding rod 4110 to move along the inner wall of the rotating seat 414 and along the inside of the rectangular groove 415. The machine moves linearly, causing the clamping blocks 4111 to move as well. Once all five clamping blocks 4111 have pressed against the outer wall of the end face of the tool body 3, the end face of the tool body 3 can be clamped and fixed, thus preventing the tool from vibrating during rotation and affecting the machining accuracy. After the tool body 3 is installed, the operator turns on the drive motor 412 to make the output shaft 413 rotate. During the rotation of the output shaft 413, the rotating seat 414 and the tool body 3 will rotate, thus enabling the machining of metal materials during the rotation of the tool body 3.

[0029] The bottom of the mounting plate 1 is fixedly connected with four support legs 2. The four support legs 2 are fixedly connected at equal intervals at the four corners of the bottom of the mounting plate 1. The four support legs 2 at the bottom of the mounting plate 1 can provide stable support for the mounting plate 1.

[0030] There are five clamping blocks 4111, and all five clamping blocks 4111 are slidably connected to one end of the outer wall of the tool body 3.

[0031] Example 2

[0032] The difference from Embodiment 1 is that this embodiment discloses auxiliary components, such as... Figure 5 As shown:

[0033] An auxiliary component 42 is also provided on the top of the mounting plate 1. The auxiliary component 42 includes a rectangular frame 421 fixedly connected to the top center of the mounting plate 1. A fixing post 422 is fixedly connected to the top inner wall of the rectangular frame 421. A first clamping block 423 and a second clamping block 424 are slidably connected to the outer center of the fixing post 422. The inner center of the first clamping block 423 is slidably connected to the outer center of the tool body 3. A spring 425 is fixedly connected to the top of the first clamping block 423. The other end of the spring 425 is fixedly connected to the top inner wall of the rectangular frame 421. By setting the auxiliary component 42, the tool body 3 needs to be supported before it is fixed. The operator presses the first clamping block 423 and the second clamping block 424 to both sides, causing them to move along the outer wall of the fixed column 422 and compress the spring 425. Then, the operator places the tool body 3 in the middle of the rectangular frame 421 and releases the first clamping block 423 and the second clamping block 424. Under the reaction of the spring 425, the first clamping block 423 and the second clamping block 424 will reset, enabling them to provide auxiliary support to the outer wall of the tool body 3, further improving the stability of the tool body 3 during rotation.

[0034] Four handles 426 are fixedly connected to the top of the four corners of the first clamping block 423. The outer wall of the first clamping block 423 is slidably connected to the inner wall of the rectangular frame 421. The handles 426 make it easy for the operator to pull the first clamping block 423 and the second clamping block 424.

[0035] The first clamping block 423 and the second clamping block 424 have the same shape and size. The first clamping block 423 and the second clamping block 424 are symmetrically distributed up and down along the center plane of the tool body 3. When the first clamping block 423 and the second clamping block 424 clamp the tool body 3, they can provide auxiliary support for the tool body 3 and improve the stability of the tool body 3 in the process of processing metal materials.

[0036] Working principle: Before fixing the tool body 3, auxiliary support is first required. The operator presses the first clamping block 423 and the second clamping block 424 to both sides, causing the first clamping block 423 and the second clamping block 424 to move along the outer wall of the fixing column 422 and compress the spring 425. Then, the operator places the tool body 3 in the middle of the rectangular frame 421 and releases the first clamping block 423 and the second clamping block 424. Under the reaction of the spring 425, the first clamping block 423 and the second clamping block 424 will be reset, so that the first clamping block 423 and the second clamping block 424 can provide auxiliary support for the outer wall of the tool body 3, further improving the stability of the tool body 3 during rotation.

[0037] In the CNC machining process, to improve the stability of the tool body 3 during the machining of metal materials, the tool body 3 first needs to be installed and fixed. The operator aligns the end face of the tool body 3 with the side wall of the rotating seat 414, and then starts the forward and reverse motor 416 to cause the rotating shaft 417 to rotate. During the rotation of the rotating shaft 417, the disc 418 will rotate. After the disc 418 rotates, the sliding rod 4110 will be pressed by the internal arc groove 419, causing the sliding rod 4110 to move along the inner wall of the rotating seat 414 and along the rectangular... The groove 415 moves linearly inside, driving the clamping blocks 4111 to move until all five clamping blocks 4111 press against the outer wall of the end face of the tool body 3, thereby clamping and fixing the end face of the tool body 3. This prevents the tool from vibrating during rotation, which would affect the machining accuracy. After the tool body 3 is installed, the operator turns on the drive motor 412 to make the output shaft 413 rotate. During the rotation of the output shaft 413, it will drive the rotating seat 414 and the tool body 3 to rotate, thus enabling the machining of metal materials during the rotation of the tool body 3.

[0038] The above description is merely an illustrative embodiment of this utility model and is not intended to limit the scope of this utility model. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of this utility model should fall within the protection scope of this utility model. Furthermore, it should be noted that the components of this utility model are not limited to the overall application described above. Each technical feature described in the specification of this utility model can be used individually or in combination as needed. Therefore, this utility model naturally covers other combinations and specific applications related to this application.
