Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a CNC machine tool for processing hardware parts. Background Technology

[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, input them into the CNC device through an information carrier, and after calculation and processing, the CNC device sends out various control signals to control the machine tool's movements. It automatically processes parts according to the shape and size required by the drawings and is a widely used machining equipment.

[0003] Existing CNC machine tools have the following drawbacks when processing hardware parts: Compared with large workpieces, hardware parts are relatively small in size. When processing hardware parts using CNC machine tools, mass production is usually carried out. Due to the large quantity and small size of the parts, frequent loading and unloading are required. Existing CNC machine tools must be stopped before loading and unloading operations can be carried out. The downtime during loading and unloading is long and has a significant impact on production efficiency. Therefore, we propose a CNC machine tool for processing hardware parts. Utility Model Content

[0004] The main purpose of this utility model is to provide a CNC machine tool for processing hardware parts. By improving the loading and unloading structure of the CNC machine tool, the downtime during the loading and unloading process can be reduced, the processing efficiency can be improved, and the problems in the background art can be effectively solved.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0006] A CNC machine tool for processing hardware parts includes a machine tool body and a loading / unloading mechanism. The loading / unloading mechanism is provided inside the machine tool body. The loading / unloading mechanism includes through holes, guide tables, slots, fixed tables, insert plates, base plates, and positioning blocks. Through holes are provided on both sides of the surface of the machine tool body. Guide tables are provided inside the machine tool body, and both ends of the guide tables extend through the through holes to the outside of the machine tool body. Slots are provided between the guide tables. A fixed table is detachably connected to the top of the guide tables. An insert plate inserted into the slot is fixedly connected to the bottom of the fixed table, and a base plate is fixedly connected to the bottom of the insert plate. A positioning block is fixedly connected to the middle position of the bottom of the base plate.

[0007] Furthermore, it also includes a positioning mechanism. The positioning mechanism is provided inside the machine tool body. The positioning mechanism includes a hydraulic cylinder, a ferrule, a side slide plate, a locking block, and a positioning groove. The hydraulic cylinder is installed at the bottom of the guide table inside the machine tool body. The power output end of the hydraulic cylinder is equipped with a ferrule corresponding to the position of the positioning block. The inner walls of the ferrule are integrally formed with side slide plates on both sides, and the inner walls of the ferrule are fixedly connected with locking blocks. The surface of the positioning block is provided with positioning grooves corresponding to the positions of the locking blocks on both sides. When the sliding fixed plate is moved to the processing position, the power end of the hydraulic cylinder lifts the ferrule. The ferrule can only move in the vertical direction. When it approaches the bottom of the positioning block, it will fit into the outer periphery of the positioning block. At this time, the locking block is just locked into the positioning groove, thereby fixing the position of the positioning block, and thus fixing the position of the fixed table and the workpiece on top, maintaining its positional stability during the processing. After processing is completed, the power end of the hydraulic cylinder retracts, and the fixed table can be removed for workpiece removal.

[0008] Furthermore, a main protective door is slidably connected to one side of the machine tool body surface in the horizontal direction; the main protective door can protect the operator's front during the machining process of the machine tool body.

[0009] Furthermore, side protective doors are vertically slidably connected inside the through holes of the machine tool body; during processing, the side protective doors are in a closed state, which protects the through holes on both sides of the machine tool body.

[0010] Furthermore, the bottom of the positioning block has side slopes on both sides, and the angle of the side slopes corresponds to that of the side slide plate; the side slopes correspond to the side slide plate, so that the sleeve can be inserted into the outer periphery of the positioning block more smoothly.

[0011] Compared with the prior art, this utility model has the following advantages: The machine tool body has a guide platform structure inside, and the guide platform extends through a through hole to both sides of the machine tool body. A fixed platform can be inserted into the top of the guide platform. The top of the fixed platform is used to install fixtures and position the workpiece. When using the machine tool body to produce hardware parts, fixtures can be added to the top of multiple fixed platforms and their positions calibrated. During operation, a set of fixed platforms and the workpiece are moved into the internal processing position of the machine tool body for processing. After processing, they slide out along the side of the guide platform. During processing, other workpieces can be loaded and unloaded from the top of the platform. After loading, the workpiece is inserted into the end of the guide platform for preparation. In the machine tool area, after the workpiece is processed, the side protective door can be opened directly to slide it into the machine tool body and position it. This is suitable for batch production of small-sized hardware parts, shortening the downtime for loading and unloading and improving processing efficiency. When the sliding fixed plate is moved to the processing position, the hydraulic cylinder power end lifts the ferrule. The ferrule can only move in the vertical direction. When it approaches the bottom of the positioning block, it will fit into the outer periphery of the positioning block. At this time, the ferrule is just locked into the positioning groove, thus fixing the position of the positioning block, thereby fixing the position of the fixed table and the workpiece on top, maintaining its positional stability during the processing. After processing is completed, the hydraulic cylinder power end retracts, and the fixed table can be removed for part removal. Attached Figure Description

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] like Figure 1-4 As shown, a CNC machine tool for processing hardware parts includes a machine tool body 1 and a loading / unloading mechanism 2. The loading / unloading mechanism 2 is provided inside the machine tool body 1. The loading / unloading mechanism 2 includes a through hole 202, a guide table 203, a slot 204, a fixed table 206, an insert plate 207, a base plate 208, and a positioning block 209. Through holes 202 are provided on both sides of the surface of the machine tool body 1. The guide table 203 is provided inside the machine tool body 1, and both ends of the guide table 203 extend through the through holes 202 to the outside of the machine tool body 1. A slot 204 is provided between the guide tables 203. The fixed table 206 is detachably connected to the top of the guide table 203. The insert plate 207, which is inserted into the slot 204, is fixedly connected to the bottom of the fixed table 206. The base plate 208 is fixedly connected to the bottom of the insert plate 207. The positioning block 209 is fixedly connected to the middle position of the bottom of the base plate 208.

[0019] The machine tool body 1 also includes a positioning mechanism 3. The positioning mechanism 3 is installed inside the machine tool body 1. The positioning mechanism 3 includes a hydraulic cylinder 301, a ferrule 302, a side slide plate 303, a locking block 304, and a positioning groove 306. The hydraulic cylinder 301 is installed at the bottom of the guide platform 203 inside the machine tool body 1. A ferrule 302 corresponding to the position of the positioning block 209 is installed at the power output end of the hydraulic cylinder 301. Side slide plates 303 are integrally formed on both sides of the inner wall of the ferrule 302, and locking blocks 304 are fixedly connected to the inner wall of the ferrule 302. The positioning block 209 has openings on both sides of its surface. There is a positioning groove 306 corresponding to the position of the locking block 304; when the sliding fixed plate is moved to the processing position, the hydraulic cylinder 301 pushes the sleeve 302 with its power end. The sleeve 302 can only move in the vertical direction. When it approaches the bottom of the positioning block 209, it will fit into the outer periphery of the positioning block 209. At this time, the locking block 304 is just locked into the positioning groove 306, thereby fixing the position of the positioning block 209, and thus fixing the position of the fixed table 206 and the top workpiece, maintaining its positional stability during the processing. After the processing is completed, the hydraulic cylinder 301 retracts with its power end, and the fixed table 206 can be moved out for the part to be picked up.

[0020] The machine tool body 1 has a main protective door 201 that is slidably connected horizontally on one side of its surface, and side protective doors 205 that are slidably connected vertically inside the through holes 202. The main protective door 201 can protect the operator's front during the machining process of the machine tool body 1, while the side protective doors 205 are closed during the machining process to protect the through holes 202 on both sides of the machine tool body 1.

[0021] The positioning block 209 has side slopes 305 on both sides of its bottom, and the side slopes 305 are angled to the side slide plate 303. The side slopes 305 and the side slide plate 303 are aligned so that the sleeve 302 can be inserted into the outer periphery of the positioning block 209 more smoothly.

[0022] It should be noted that this utility model is a CNC machine tool for processing hardware parts. During operation, the machine tool body 1 has a guide table 203 structure inside, and the guide table 203 extends to both sides of the outside of the machine tool body 1 through the through hole 202. A fixed table 206 can be inserted into the top of the guide table 203. The top of the fixed table 206 is used to install fixtures and position the workpiece. When using the machine tool body 1 to produce hardware parts, fixtures can be added to the top of multiple sets of fixed tables 206 and their positions can be calibrated. During operation, a set of fixed tables 206 and the workpiece are moved into the internal processing position of the machine tool body 1 for processing. After processing, the workpiece slides out along the side of the guide table 203. During the processing, other workpieces can be loaded and unloaded from the top of the workpiece table. After loading, the workpiece is inserted into the guide table 203. In the end spare area, after the workpiece is processed, the side protective door 205 can be opened directly and the workpiece can be slid into the machine tool body 1 and positioned. This is suitable for batch production of small-sized hardware parts, shortening the downtime for loading and unloading and improving processing efficiency. When the sliding fixed plate is moved to the processing position, the hydraulic cylinder 301 lifts the sleeve 302. The sleeve 302 can only move in the vertical direction. When it approaches the bottom of the positioning block 209, it will fit into the outer periphery of the positioning block 209. At this time, the locking block 304 is just locked into the positioning groove 306, which fixes the position of the positioning block 209, thereby fixing the position of the fixed table 206 and the workpiece on top, maintaining its positional stability during the processing. After the processing is completed, the hydraulic cylinder 301 retracts, and the fixed table 206 can be removed for part removal.
