Description

Technical Field

[0001] This utility model relates to the field of five-axis machining centers, specifically a tool removal structure for a five-axis machining center. Background Technology

[0002] A five-axis machining center is a high-tech, high-precision machining center specifically designed for machining complex curved surfaces. It belongs to the category of advanced CNC machine tools and has five independent motion axes. In addition to the three linear axes (X, Y, and Z), it adds rotary axes (A and C axes), enabling machining of workpieces at different angles. Through the combined motion of these five axes, multiple surfaces of a workpiece can be precisely cut and machined in a single setup. To facilitate the installation and removal of the tool head, a tool-retrieving structure is required. The "Tool Retrieving Structure for a Five-Axis Machining Center" disclosed in application number "202410633771.8" represents an increasingly mature technology. The technology, by setting a limit slider and a sealing plate in combination, forms a sealed cavity between the sealing plate, the limit slider, the fixing frame, and the front cover. Air is supplied from inside the cavity through an air supply pipe, and guided by a traction rope. While stretching the elastic element, the two clamping bars move towards each other, thereby clamping the tool. When the tool is removed, the air pump extracts the gas, and the elastic element drives the clamping bars to reset. This solves the technical problem in existing machining centers where the tool clamping may not be calibrated in time during tool magazine operation, leading to easy tool damage. It achieves the technical effect of enhancing the stability of the clamping mechanism, providing double protection for tool clamping, and reducing the risk of tool damage.

[0003] However, this tool-retrieving structure has the following drawbacks during use: While it can indeed grip the tool head using the clamping bar, elastic element, and traction rope, it is not convenient to grip tool heads of different sizes, thus limiting its usability. Therefore, it is necessary to provide a tool-retrieving structure that can easily grip tool heads of different sizes and enhance its versatility. In addition, this tool-retrieving structure is not convenient to grip tool heads of different heights as needed, thus affecting ease of use. Therefore, it is necessary to provide a gripping structure that is easy to adjust in height and improves ease of use. Utility Model Content

[0004] This utility model provides a tool retrieval structure for a five-axis machining center, aiming to solve the problem that existing tool retrieval structures are inconvenient for clamping tool heads of different heights and sizes.

[0005] To achieve the above objectives, this utility model provides a tool-retrieving structure for a five-axis machining center, including a tool-retrieving assembly and a lifting assembly;

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1 - Figure 4 This utility model provides a tool retrieval structure for a five-axis machining center, including a tool retrieval assembly 100 and a lifting assembly 200;

[0027] The knife-removing assembly 100 includes two crossbeams 101. Each of the two crossbeams 101 is rotatably connected to a lead screw 102 and a guide rod 103. The side surfaces of the lead screw 102 and the guide rod 103 are provided with two movable plates 104. The opposing surfaces of the two movable plates 104 are each fitted with a clamping plate 105. A transmission mechanism 106 is installed at one end of the lead screw 102.

[0028] The lifting assembly 200 includes a base frame 201. Toothed plates 202 are fixedly connected to both sides of the upper end of the base frame 201. Toothed grooves 203 are formed on the opposite surfaces of the two toothed plates 202. Guide beams 204 are installed at the upper ends of each pair of toothed plates 202. Connecting plates 205 are fixedly connected to the lower ends of the two guide beams 204. First transmission gears 206 and second transmission gears 207 are rotatably connected to both ends of the two connecting plates 205, respectively. Transmission rods 208 are fixedly connected between the two first transmission gears 206 and the two second transmission gears 207. A rotating mechanism 209 is installed at one end of the transmission rod 208 within the two second transmission gears 207.

[0029] In one specific embodiment, the tool-grabbing assembly 100, in conjunction with the lifting assembly 200, not only facilitates the automatic clamping of tool heads of different sizes, thus enhancing the versatility of the tool-grabbing structure, but also facilitates the clamping of tool heads of different heights, thereby improving the ease of use of the tool-grabbing structure. In use, the rotating mechanism 209 is first activated, causing the transmission rods 208 within the two second transmission gears 207 to rotate, which in turn rotates the two second transmission gears 207 and the first transmission gear 206, thereby controlling the two first transmission gears 207... 06 and the second transmission gear 207 move up and down along the tooth groove 203, thereby adjusting the height of the guide beam 204. Then, the transmission mechanism 106 is started to rotate the lead screw 102. With the help of the guide rod 103, the two moving plates 104 can be controlled to reciprocate along the lead screw 102 and the guide rod 103. The clamping plates 105 on the opposite side of the two moving plates 104 can clamp the blades of different sizes. The two rubber clamping plates 105 can be squeezed and deformed according to the size of the blade, thereby enhancing the clamping stability of blades of different sizes and thus enhancing the versatility of the blade removal structure.

[0030] Please see Figure 2 The transmission mechanism 106 includes a first synchronous pulley 1061 mounted on one end of the lead screw 102, a first motor 1062 mounted on the lower end of a crossbeam 101, a second synchronous pulley 1063 mounted on the output end of the first motor 1062, and a synchronous belt 1064 connecting the first synchronous pulley 1061 and the second synchronous pulley 1063.

[0031] In one specific embodiment, the first motor 1062 is started to rotate the second synchronous pulley 1063, which in turn rotates the first synchronous pulley 1061 with the synchronous belt 1064, and then rotates the lead screw 102, so as to control the two moving plates 104 to move closer to each other to clamp the cutter heads of different sizes.

[0032] Please see Figure 2 Two limiting grooves 111 are provided on the opposite sides of the two movable plates 104, and two limiting strips 112 are fixedly connected to the opposite sides of the two clamping plates 105. The two limiting strips 112 are slidably connected inside the limiting grooves 111.

[0033] In one specific embodiment, the limiting strip 112 is snapped into the limiting groove 111, thereby improving the ease of assembly and disassembly between the clamping plate 105 and the moving plate 104.

[0034] Please see Figure 2 Both ends of the crossbeam 101 are fixedly connected to the locking blocks 121, and the lower end of the crossbeam 101 is fixedly connected to two fixing blocks 122.

[0035] In one specific embodiment, the locking block 121, in conjunction with the fixing block 122, can improve the installation stability between the crossbeam 101 and the guide beam 204.

[0036] Please see Figure 3 and Figure 4 Guide bars 131 are fixedly installed at both ends of the movable plate 104.

[0037] In one specific embodiment, the guide bar 131 is used to improve the stability and smoothness of the moving plate 104 during reciprocating motion.

[0038] Please see Figure 3 and Figure 4 The rotating mechanism 209 includes a first transmission disc 2091 installed at one end of the transmission rod 208, a second motor 2092 installed at the upper end of the base frame 201, a second transmission disc 2093 installed at the output end of the second motor 2092, and a transmission belt 2094 connecting the first transmission disc 2091 and the second transmission disc 2093.

[0039] In one specific embodiment, by starting the second motor 2092 to rotate the second transmission disk 2093, and cooperating with the transmission belt 2094 to rotate the first transmission disk 2091 and the transmission rod 208 on its surface, the stability of the tool-removing structure during lifting and lowering can be improved.

[0040] Please see Figure 3 and Figure 4 The upper end of the toothed plate 202 is provided with a positioning groove 211, and the lower end of the guide beam 204 is fixedly installed with two positioning rods 212, which are inserted into the positioning groove 211.

[0041] In one specific embodiment, the positioning rod 212 is inserted into the positioning groove 211, which can play a positioning role when the guide beam 204 is raised or lowered, thereby improving the stability of the guide beam 204 during the raising and lowering process.

[0042] Please see Figure 2 - Figure 4 The upper surface of the guide beam 204 has a slot 221 and a fixing slot 222 at both ends. The locking block 121 is engaged in the inside of the slot 221, and the fixing block 122 is engaged in the inside of the fixing slot 222. The opposite surfaces of the two guide beams 204 have guide grooves 223, and the guide strip 131 is slidably connected in the inside of the guide groove 223.

[0043] In one specific embodiment, the locking block 121 is engaged in the locking groove 221, and the fixing block 122 is engaged in the fixing groove 222. Therefore, the ease of disassembly and assembly and the installation stability between the guide beam 204 and the crossbeam 101 can be improved. The stability of the moving plate 104 when moving along the guide beam 204 can be improved by moving the guide bar 131 along the guide groove 223.

[0044] Working principle: In use, the rotating mechanism 209 is first started, which drives the transmission rods 208 inside the two second transmission gears 207 to rotate clockwise or counterclockwise. This drives the two second transmission gears 207 and the first transmission gear 206 to rotate, thereby controlling the two first transmission gears 206 and the second transmission gears 207 to rise and fall along the tooth grooves 203, so as to adjust the height of the guide beam 204. Then, the transmission mechanism 106 is started, which drives the lead screw 102 to rotate. With the help of the guide rod 103, the two moving plates 104 can be controlled to reciprocate along the lead screw 102 and the guide rod 103. The clamping plates 105 on the opposite sides of the two moving plates 104 can clamp the blades of different sizes. At the same time, the two rubber clamping plates 105 can be squeezed and deformed according to the size of the blade, thereby enhancing the clamping stability of blades of different sizes and significantly enhancing the versatility and ease of use of the blade removal structure.
