Description

Technical Field

[0001] This utility model relates to the field of CNC machine tool technology, and in particular to a CNC machine tool with an anti-scalding structure. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. CNC machine tools can effectively process workpieces into the shapes and dimensions required by drawings. However, conventional CNC machine tools have some drawbacks in use, such as:

[0003] For example, in application number "CN202322881546.X", a CNC machine tool fixture that is easy to disassemble cannot be protected during the material handling process. The workpiece needs to be removed by hand. The finished workpiece is usually at a high temperature, so it cannot provide effective protection and makes it easy for the operator to be injured. Utility Model Content

[0004] The purpose of this invention is to provide a CNC machine tool with an anti-scalding structure to solve the problems mentioned in the background art.

[0005] A CNC machine tool with an anti-scalding structure includes a machine tool body, a three-jaw chuck, and a limit frame: a fixed frame is provided on one side of the upper end of the machine tool body, a three-jaw chuck is provided on the side of the fixed frame, a limit frame is provided on the other side of the upper end of the machine tool body, a support mechanism is provided on the rear side of the machine tool body, an adjustment mechanism is provided inside the support mechanism, and a clamping and protective mechanism is provided on the side of the adjustment mechanism.

[0006] The fixed frame allows operation of the three-jaw chuck and the machine tool body to clamp the workpiece. The limit frame then moves the cutting tool to limit and rotate the workpiece, facilitating its processing.

[0007] Preferably, the support mechanism includes a support frame, a motor, and a lead screw. The side of the support frame is located on the side of the machine tool body. The motor is installed on the side of the support frame, and the output end of the motor is connected to the lead screw. The lead screw is rotatably installed inside the support frame.

[0008] Preferably, the adjustment mechanism includes a first electric push rod and a second electric push rod. The first electric push rod is divided into upper and lower sections. The lower section of the first electric push rod is penetrated by a lead screw, and the upper section of the first electric push rod is the main telescopic part. The first electric push rod is slidably disposed inside the support frame, and the extended end of the first electric push rod is provided with a second electric push rod.

[0009] When the device is in use, the motor drives the lead screw to rotate. Since the lead screw and the lower section of the first electric push rod are threaded together, and the support frame limits the first electric push rod, the first electric push rod can only move laterally. This allows the positions of the first and second electric push rods to be adjusted, so that the clamping and protective mechanism can be located at different positions on the workpiece. The first electric push rod will drive the second electric push rod and the clamping and protective mechanism to move up and down, thereby adjusting the height of the clamping and protective mechanism.

[0010] Preferably, the clamping and protective mechanism includes a support rod and a clamping plate. The support rod is the extended end of the second electric push rod. The clamping plate is symmetrically arranged inside the end of the support rod away from the second electric push rod. The clamping plate is V-shaped.

[0011] The second electric push rod can drive the support rod to move back and forth, thereby adjusting the position of the clamping plate to move closer to or further away from the workpiece. The workpiece is then clamped by the clamping plate. Since the temperature of the processed workpiece is high, the clamping plate can effectively hold the workpiece. Afterwards, the position of the workpiece is adjusted by moving the clamping plate, and a new workpiece is installed inside the three-jaw chuck. This avoids the operator from directly handling the workpiece, thus protecting the workers. After the workpiece cools down, the workpiece inside the clamping plate can be removed. This improves processing efficiency and also protects the workers.

[0012] Preferably, a fixed cover is provided at the end of the support rod away from the second electric push rod, a dual-axis motor is provided inside the support rod, and output shafts are provided on both sides of the dual-axis motor, with the other end of the output shaft connected to the clamping plate.

[0013] When the device is in use, the output shaft is driven to rotate by the dual-axis motor, and the clamping plate will rotate with the output shaft. The position of the two clamping plates can be adjusted by the two dual-axis motors, so that workpieces at different angles can be clamped. The dual-axis motor has a self-locking function. The fixed cover and the support rod are fixed by bolts, so the fixed cover can be removed to expose the dual-axis motor inside.

[0014] Preferably, clamping blocks are provided on the opposing sides of the two clamping plates.

[0015] The clamping blocks can increase the contact area between the clamping plate and the workpiece, thereby improving the clamping effect of the device.

[0016] Preferably, the clamping block is made of rubber material.

[0017] Because the clamping block is elastic, it can undergo a certain degree of deformation, further improving the clamping effect of the holding plate.

[0018] The beneficial effects of this utility model are:

[0019] 1. When the device is in use, it uses a three-jaw chuck to limit the workpiece before processing it. After processing, the workpiece is clamped by a clamping plate, and then a new workpiece is placed in for processing. The parts clamped inside the clamping plate are cooled down before being removed, thus achieving a protective effect and avoiding burns to personnel during the material handling process, while also improving processing efficiency.

[0020] 2. The lateral position of the clamping plate can be adjusted by using the lead screw. The height of the clamping plate and the distance from the workpiece can be adjusted by the first electric push rod and the second electric push rod, which facilitates clamping workpieces in different positions.

[0027] 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.

[0028] In practical implementation: such as Figure 1-4 As shown, a CNC machine tool with an anti-scalding structure includes a machine tool body 1, a three-jaw chuck 3, and a limit frame 4. A fixed frame 2 is provided on one side of the upper end of the machine tool body 1, and a three-jaw chuck 3 is provided on the side of the fixed frame 2. A limit frame 4 is provided on the other side of the upper end of the machine tool body 1. A support mechanism is provided on the rear side of the machine tool body 1. An adjustment mechanism is provided inside the support mechanism, and a clamping and protective mechanism is provided on the side of the adjustment mechanism.

[0029] The fixed frame 2 allows operation of the three-jaw chuck 3 and the machine tool body 1, thereby clamping the workpiece. The limit frame 4 then drives the tool to move, thereby limiting and rotating the workpiece, which facilitates the processing of the workpiece.

[0030] The support mechanism includes a support frame 5, a motor 6, and a lead screw 7. The side of the support frame 5 is on the side of the machine tool body 1. The motor 6 is installed on the side of the support frame 5. The output end of the motor 6 is connected to the lead screw 7. The lead screw 7 is rotatably installed inside the support frame 5.

[0031] The adjustment mechanism includes a first electric push rod 8 and a second electric push rod 9. The first electric push rod 8 is divided into upper and lower sections. The lower section of the first electric push rod 8 is penetrated by a lead screw 7, and the upper section of the first electric push rod 8 is the main telescopic part. The first electric push rod 8 is slidably installed inside the support frame 5, and the extended end of the first electric push rod 8 is provided with the second electric push rod 9.

[0032] When the device is in use, the motor 6 drives the lead screw 7 to rotate. Since the lead screw 7 and the lower section of the first electric push rod 8 are threadedly connected, and the support frame 5 limits the first electric push rod 8, the first electric push rod 8 can only move laterally. This allows the positions of the first electric push rod 8 and the second electric push rod 9 to be adjusted, so that the clamping and protective mechanism can be located at different positions on the workpiece. The first electric push rod 8 will drive the second electric push rod 9 and the clamping and protective mechanism to move up and down, thereby adjusting the height of the clamping and protective mechanism.

[0033] The clamping and protective mechanism includes a support rod 10 and a clamping plate 14. The support rod 10 is the extended end of the second electric push rod 9. The clamping plate 14 is symmetrically arranged inside the end of the support rod 10 away from the second electric push rod 9. The clamping plate 14 is V-shaped.

[0034] The second electric push rod 9 can drive the support rod 10 to move back and forth, thereby adjusting the position of the clamping plate 14 to move closer to or further away from the workpiece. The workpiece is then clamped by the clamping plate 14. Since the temperature of the processed workpiece is high, the clamping plate 14 can effectively clamp the workpiece. Afterwards, the position of the workpiece is adjusted by moving the clamping plate 14, and a new workpiece is installed inside the three-jaw chuck 3. This avoids the operator from directly picking up the workpiece, thus protecting the workers. After the workpiece cools down, the workpiece inside the clamping plate 14 can be removed. This not only improves the processing efficiency but also protects the workers.

[0035] A fixed cover 11 is provided at the end of the support rod 10 away from the second electric push rod 9. A dual-axis motor 12 is provided inside the support rod 10, and output shafts 13 are provided on both sides of the dual-axis motor 12. The other end of the output shaft 13 is connected to the clamping plate 14.

[0036] When the device is in use, the output shaft 13 is driven to rotate by the dual-axis motor 12, and the clamping plate 14 will rotate with the output shaft 13. The positions of the two clamping plates 14 can be adjusted by the two dual-axis motors 12 respectively, so that workpieces at different angles can be clamped. The dual-axis motor 12 has a self-locking function. The fixed cover 11 is fixed to the support rod 10 by bolts, so the fixed cover 11 can be removed to expose the dual-axis motor 12 inside.

[0037] Clamping blocks 15 are provided on the opposing sides of the two clamping plates 14.

[0038] The clamping block 15 can increase the contact area between the clamping plate 14 and the workpiece, thereby improving the clamping effect of the device.

[0039] The clamping block 15 is made of rubber material.

[0040] Because the clamping block 15 is elastic, it can undergo a certain deformation, which further improves the clamping effect of the holding plate 14.
