Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, specifically to a CNC machining tool for metal parts. Background Technology

[0002] CNC machine tools effectively solve the problem of machining complex, precise, small-batch, and multi-variety parts. They are flexible, high-efficiency automated machine tools that represent the development direction of modern machine tool control technology and are a typical mechatronics product.

[0003] For example, a CNC machining tool for metal parts, with authorization announcement number "CN221065436U", uses a chuck that slides along the power shaft towards the grippers. When the chuck approaches, the pressure groove contacts the three grippers, and as the chuck moves closer, it continuously compresses and contracts the three grippers, thus clamping and securing the metal part. This method is simple, convenient, and saves time on loading and unloading. However, when machining metal parts, the operator needs to manually change the material. Furthermore, metal parts have different shapes, requiring different grippers to be used for different parts. Changing the grippers takes a considerable amount of time, resulting in low efficiency when using this device. Utility Model Content

[0004] The purpose of this invention is to solve the problem of low work efficiency caused by the inconvenience of changing the grippers in this device, and to propose a CNC machining tool for metal parts.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a CNC machine tool for machining metal parts, including a housing and a spindle box. The spindle box is fixedly connected to the inner wall of the housing. The right end of the spindle box is rotatably connected to a three-jaw chuck. Multiple insertion rods are fixedly connected to the right end of the three-jaw chuck. The outer wall of the insertion rods is provided with a quick-change device. A bed is fixedly connected to the inner wall of the housing. The upper end of the bed is slidably connected to a support plate. A tool post is provided at the upper end of the support plate.

[0007] Preferably, the quick-change device includes a grooved plate and a slider. The grooved plate is connected to multiple insert rods through multiple through holes on its surface. The surface of the grooved plate is provided with multiple sliding grooves. The inner walls of the multiple sliding grooves are slidably connected to multiple sliders. The surfaces of the multiple sliders are provided with through holes.

[0008] Preferably, the outer wall of the slider is provided with a connecting device, and the grooved disk has a circular hole in the middle.

[0009] Preferably, the connecting device includes clamps and a long bolt. The outer walls of both clamps are provided with grooves. Both clamps on both sides are inserted into the two ends of the slider through the grooves on their surfaces. One end of the long bolt is pressed against one clamp, and the other end of the long bolt passes through both clamps and is threaded to a three-jaw chuck. The long bolt is an internal hex bolt.

[0010] Preferably, the upper end of the bed is slidably connected to the tailstock, and the outer wall of the outer shell is slidably connected to the protective door.

[0011] Preferably, a control panel is installed on the outer wall of the housing, and a handle is provided on the outer wall of the protective door.

[0012] The present invention discloses a CNC machining tool for metal parts, which has the following advantages: through the cooperation of the quick-change device and the connecting device, when the fixture needs to be changed, the operator can rotate and disassemble the six long bolts so that the grooved plate can be pulled out from the surface of the three insert rods. After flipping it over, it can be inserted back into the surface of the three insert rods, so that the fixture at the left end can be exchanged with the fixture at the right end. After installation and fixing according to the above operation, rapid processing can be performed. By allowing the fixture to be changed quickly, the device can shorten the fixture installation time and improve work efficiency. Attached Figure Description

[0023] The present invention will be further described below with reference to the accompanying drawings:

[0024] See attached document Figure 1-9 In this embodiment, a CNC machining tool for metal parts includes a housing 1 and a spindle box 3. The spindle box 3 is fixedly connected to the inner wall of the housing 1. The right end of the spindle box 3 is rotatably connected to a three-jaw chuck 7. A plurality of insertion rods 12 are fixedly connected to the right end of the three-jaw chuck 7. There are three insertion rods 12. The outer wall of the insertion rods 12 is provided with a quick-change device 8. The inner wall of the housing 1 is fixedly connected to a bed 6. The upper end of the bed 6 is slidably connected to a support plate 2. The upper end of the support plate 2 is provided with a tool post 4.

[0025] The outer wall of the slider 803 is provided with a connecting device 9. The grooved plate 801 has a round hole in the middle. The round hole in the middle of the grooved plate 801 is a through hole and its diameter is the same as the through hole on the surface of the three-jaw chuck 7. The upper end of the bed 6 is slidably connected to the tailstock 5. The tailstock 5 can center shaft workpieces. The tailstock 5 is already very mature in the existing technology and will not be described in detail here. The outer wall of the outer shell 1 is slidably connected to the protective door 10. The outer wall of the outer shell 1 is equipped with a control panel 11. The outer wall of the protective door 10 is provided with a handle.

[0026] The quick-change device 8 includes a grooved plate 801 and a slider 803. The grooved plate 801 is connected to multiple insert rods 12 through multiple through holes on its surface. The surface of the grooved plate 801 is provided with multiple sliding grooves 802. There are three sliding grooves 802 and three sliders 803. The inner walls of the multiple sliding grooves 802 are slidably connected to the multiple sliders 803. The surface of the multiple sliders 803 is provided with through holes.

[0027] The connecting device 9 includes a clamp 901 and a long bolt 902. The outer walls of both clamps 901 are provided with grooves. Both clamps 901 are inserted into the two ends of the slider 803 through the grooves on their surfaces. One end of the long bolt 902 is pressed against one clamp 901, and the other end of the long bolt 902 passes through both clamps and is threaded to the three-jaw chuck 7. The long bolt 902 is an internal hex bolt.

[0028] Working principle:

[0029] When machining metal parts:

[0030] The operator inserts two different sets of clamps 901 onto both sides of the three sliders 803. Each set of clamps 901 has three clamps. Friction allows the clamps 901 to be fixed to the surface of the sliders 803. The operator adjusts the two sets of clamps 901 to the appropriate positions and then inserts six long bolts 902 through the through holes on the surfaces of the two clamps 901 and the sliders 803. One end of each bolt 902 is threaded into the threaded hole in the sliding part of the three-jaw chuck 7, completing the installation of the clamps 901. When clamping metal parts, the three clamps 901 on the right side of the grooved disc 801 move synchronously with the three clamps on the right side. When clamping shaft-type workpieces... During machining, it is necessary to adjust the three clamps 901 on the left end so that they do not contact the metal parts (the end of the metal parts will only be inserted into the clamp 901 on the right side, not into the clamp 901 on the left side). The three clamps 901 on the left end are in contact with the surface of the three-jaw chuck 7. Start the spindle box 3 and drive the grooved plate 801 to rotate synchronously through the three-jaw chuck 7. This allows the grooved plate 801 to drive the metal workpiece to rotate synchronously through the three clamps 901, controlling the tool holder 4 to move (the lower end of the support plate 2 at the lower end of the tool holder 4 is threadedly connected to the transverse lead screw inside the bed 6, so that the lead screw can drive the tool holder 4 to move while rotating. This technology is already very mature in the existing technology and will not be described in detail here). This allows the tool on the surface of the tool holder 4 to machine the metal workpiece.

[0031] Replacement process:

[0032] When it is necessary to replace the clamp 901, the operator rotates and removes the six long bolts 902, so that the grooved plate 801 can be pulled out from the surface of the three insert rods 12. After flipping it over, it is reinserted into the surface of the three insert rods 12, so that the left clamp 901 can be interchanged with the right clamp 901. The workpieces to be processed do not include long metal workpieces such as shafts. The metal workpieces are all on the right end of the grooved plate 801 when clamped. After installing and fixing according to the above operation, rapid processing can be carried out.

[0033] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
