Description

Technical Field

[0001] This application relates to the field of CNC machine tool fixtures, and more specifically, to a high-precision flexible fixture for CNC machine tools. Background Technology

[0002] CNC machine tools are mainly used for cutting and machining the inner and outer cylindrical surfaces, inner and outer conical surfaces with arbitrary cone angles, complex rotating inner and outer curved surfaces, and cylindrical and conical threads of shaft or disc parts. They can also perform grooving, drilling, reaming, boring, and other operations. Fixtures are one of the important components of CNC machine tools.

[0003] A fixture is a device used in mechanical manufacturing to fix a workpiece in the correct position for machining or inspection; it is also called a clamp. A flexible fixture is a fixture that can adapt to changes in the shape and size of the workpiece and continue to be used.

[0004] Existing technologies include many adaptive high-precision flexible fixtures based on magnetorheological fluids. These fixtures utilize the properties of magnetorheological fluids to achieve adaptive adjustment according to the workpiece shape. However, since the change in the state of the magnetorheological fluid requires the application of a magnetic field, this magnetic field can interfere with the control system of the CNC machine tool, easily leading to control errors and data errors. This not only affects machining accuracy but, in severe cases, can even cause safety accidents. Furthermore, the magnetic field can also affect other parts or workpieces made of ferromagnetic materials, further impacting machining accuracy. Therefore, we propose a high-precision flexible fixture for CNC machine tools. Summary of the Invention

[0005] The purpose of this application is to design a high-precision flexible fixture that can adaptively adjust according to shape without affecting the CNC machine tool. Compared with the prior art, this application provides a high-precision flexible fixture for CNC machine tools, including a clamping control mechanism, a clamping adjustment intelligent controller, and a pair of adaptive gripper mechanisms. The clamping control mechanism includes a support box, in which a bidirectional cylinder with two output ends is fixedly installed. Each output end of the bidirectional cylinder is fixedly connected to an L-shaped connecting rod. The adaptive gripper mechanism includes a support frame, in which a matching adaptive clamping body is fixedly installed on the inner side. The adaptive clamping body consists of a rigid outer box, an elastic outer box matching the rigid outer box, and a hot-melt inner filling material filled inside the rigid outer box and the elastic outer box. The outer casing is made of high-temperature resistant elastic material, and the hot-melt inner filling is made of thermoplastic resin. A support cylinder is fixedly installed on the outer wall of the rigid outer casing, and an electric heating rod is fixedly installed inside the support cylinder. The electric heating rod penetrates the outer wall of the rigid outer casing and extends into the hot-melt inner filling. The clamping and adjusting intelligent controller is equipped with a central control unit and a hot-melt control module. The central control unit is electrically connected to the hot-melt control module, and the hot-melt control module is electrically connected to the electric heating rod. This allows the adaptive clamping mechanism to be adaptively adjusted according to the shape and size of the workpiece. Moreover, the adjustment of the adaptive clamping mechanism does not require an external magnetic field, so it will not affect the control system of the CNC machine tool. This not only improves the machining accuracy but also indirectly improves the machining safety.

[0006] Furthermore, both the rigid outer box and the flexible outer box are hollow boxes. The rigid outer box and the flexible outer box are sealed and fixedly connected, and the interiors of the rigid outer box and the flexible outer box are interconnected.

[0007] Furthermore, the connecting rod passes through the outer wall of the support box and is slidably connected thereto. The two connecting rods are respectively fixedly connected to the two support frames in the two adaptive gripper mechanisms. The clamping and adjusting intelligent controller is also equipped with a clamping release control module. The central control unit is electrically connected to the clamping release control module, and the clamping release control module is electrically connected to the bidirectional cylinder.

[0008] Furthermore, a temperature sensor is fixedly installed on the inner wall of the rigid outer casing, and a ringing reminder module is also set in the clamping intelligent controller. The temperature sensor is electrically connected to the ringing reminder module and the hot melt control module, which can not only improve processing efficiency, but also reduce energy waste.

[0009] Furthermore, a wide conductive mesh plate is fitted on the outer wall of the electric heating rod. The wide conductive mesh plate is made of thermally conductive material, which can improve the heating efficiency of the hot melt inner filling, thereby indirectly improving the processing efficiency. The support frame, rigid outer box, and support cylinder are all made of heat insulation material, which can reduce heat loss and thus reduce energy waste.

[0010] Optionally, a rapid descent efficiency-enhancing component is installed within the support frame. This component includes a cooler, an insulation pipe, a descending guide rod, and a spacer rod that matches the descending guide rod. The cooler is embedded through the outer wall of the support frame. The two ends of the insulation pipe are sealed and fixedly connected to the support frame and the rigid outer box, respectively. The descending guide rod is fixedly connected to the wide guide mesh plate, and the spacer rod is fixedly connected to the descending guide rod. The spacer rod penetrates the outer wall of the rigid outer box and is slidably and sealed therewith. The clamping and adjusting intelligent controller also includes a cooling control module. The cooler and the spacer rod are located inside the insulation pipe, which is made of heat-insulating material. The central control unit is electrically connected to the cooling control module, which is electrically connected to the cooler. The wide guide mesh plate is slidably connected to the electric heating rod. The wide guide mesh plate has a porous mesh structure, and elastic pull ropes are fixedly connected to both the upper and lower ends of the wide guide mesh plate. The other end of the elastic pull rope is fixedly connected to the inner wall of the rigid outer box, which can accelerate the cooling and hardening of the hot-melt inner filling, thereby further improving processing efficiency.

[0011] Optionally, the clamping and adjusting intelligent controller also includes a detection control module and a detection analysis module. A detection assembly is installed within the support frame, comprising a detection adjustment box embedded through the outer wall of the support frame. An electric telescopic rod and a color recognition sensor are fixedly installed inside the detection adjustment box. A detection linkage rod is fixedly connected to the output end of the electric telescopic rod. A color recognition mark is provided on the outer wall of the detection linkage rod. The detection linkage rod is T-shaped and penetrates the outer wall of the detection adjustment box, the outer wall of the rigid outer casing, and the wide guide mesh plate. The detection linkage rod is slidably connected to the outer wall of the detection adjustment box and the wide guide mesh plate, and the detection linkage rod is slidably sealed to the outer wall of the rigid outer casing. Next, the color recognition mark is painted with pigment and is located on the outside of the detection and adjustment box. The temperature sensor is electrically connected to the central control unit, the central control unit is electrically connected to the detection control module, the detection control module is electrically connected to the detection and adjustment box and the color recognition sensor, the color recognition sensor is electrically connected to the detection and analysis module, and the detection and analysis module is electrically connected to the ringing reminder module. The ringing reminder module can emit at least three different ringtones, so that the melting detection component can detect and verify whether the hot melt inner filling has completely melted. This can not only further improve the processing accuracy, but also improve the intelligence of the fixture, and indirectly improve the processing efficiency, greatly improving practicality.

[0012] Furthermore, a light source is fixedly installed inside the detection adjustment box. The central control unit is electrically connected to the light source. When the central control unit issues a detection command to the detection control module, it also activates the light source to illuminate the inside of the detection adjustment box. This facilitates the color recognition sensor's recognition of color markings and improves the accuracy of the detection and verification functions of the fusion testing component.

[0013] Compared to existing technologies, the advantages of this application are:

[0014] (1) This application enables the adaptive gripper mechanism to be adaptively adjusted according to the shape and size of the workpiece by combining the adaptive gripper mechanism and the clamping intelligent controller. The adaptive clamping body in the adaptive gripper mechanism can be deformed into a shape that matches the workpiece, so that it can be tightly attached to the surface of the workpiece, thereby firmly and stably clamping the workpiece. Moreover, the adjustment of the adaptive gripper mechanism does not require an external magnetic field, so it will not affect the control system of the CNC machine tool, etc., thereby not only improving the machining accuracy, but also indirectly improving the machining safety.

[0015] (2) A temperature sensor is fixedly installed on the inner wall of the rigid outer box. The clamping and adjusting intelligent controller is also equipped with a ringing reminder module. The temperature sensor is electrically connected to the ringing reminder module and the temperature sensor is electrically connected to the hot melt control module. This not only improves processing efficiency but also reduces energy waste.

[0016] (3) A wide conductive mesh plate is fitted on the outer wall of the electric heating rod. The wide conductive mesh plate is made of heat-conducting material, which can improve the heating efficiency of the hot melt inner filling, thereby improving the processing efficiency. The support frame, rigid outer box and support cylinder are all made of heat insulation material, which can reduce heat loss and thus reduce energy waste.

[0017] (4) By setting up the speed reduction efficiency improvement component, the cooling and hardening of the hot melt inner filler can be accelerated, thereby further improving the processing efficiency.

[0018] (5) By setting up the clamping and adjusting intelligent controller, the melting detection component can detect and verify whether the hot melt inner filling has been completely melted. The melting detection component can also feed back the detection and verification results to the staff through the ringing reminder module. If the ringing reminder module emits a second ring, the staff can directly carry out subsequent operations. If the ringing reminder module emits a second ring, the hot melt inner filling needs to be heated again. This can not only further improve the processing accuracy, but also improve the intelligence level of the fixture and indirectly improve the processing efficiency, thus greatly improving the practicality.

[0019] (6) A light source is fixedly installed inside the detection adjustment box. The central control unit is electrically connected to the light source. When the central control unit issues a detection command to the detection control module, it will also start the light source to illuminate the inside of the detection adjustment box. This will help the color recognition sensor to recognize the color mark, thereby improving the accuracy of the detection and verification functions of the fusion assembly.

[0033] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0034] Example 1

[0035] This application discloses a high-precision flexible fixture for CNC machine tools. Please refer to [link / reference]. Figure 1-5The system includes a clamping mechanism, a clamping intelligent controller 003, and a pair of adjustable gripper mechanisms. The clamping mechanism includes a support box 101, inside which a bidirectional cylinder 102 with two output ends is fixedly installed. Each output end of the bidirectional cylinder 102 is fixedly connected to an L-shaped connecting rod 103. The adjustable gripper mechanism includes a support frame 201, on the inner side of which a matching adjustable clamping body is fixedly installed. The adjustable clamping body consists of a rigid outer box 202, an elastic outer box 203 matching the rigid outer box 202, and a hot-melt inner filling 204 filled inside the rigid outer box 202 and the elastic outer box 203. All boxes 203 are hollow boxes. The rigid outer box 202 and the elastic outer box 203 are sealed and fixedly connected, and the interiors of the rigid outer box 202 and the elastic outer box 203 are connected. The elastic outer box 203 is made of high-temperature resistant elastic material, and the hot-melt inner filling 204 is made of thermoplastic resin material. A support cylinder 205 is fixedly installed on the outer wall of the rigid outer box 202, and an electric heating rod 206 is fixedly installed inside the support cylinder 205. The electric heating rod 206 penetrates the outer wall of the rigid outer box 202 and extends into the hot-melt inner filling 204. The clamping intelligent controller 003 is equipped with a central control unit and a hot-melt control module. The central control unit and the hot-melt control module are electrically connected. The hot melt control module is electrically connected to the electric heating rod 206. During use, the central control unit sends a heating command to the hot melt control module. Upon receiving the command, the hot melt control module activates the electric heating rod 206, heating the hot melt inner filling body 204 until it melts. The workpiece is then placed between two adjusting jaw mechanisms. The clamping mechanism moves these mechanisms, ensuring they are tightly against both ends of the workpiece. During this contact, the hot melt inner filling body 204 is molten, causing the elastic outer box 203 to deform and adjust according to the shape of the workpiece. After the hot-melted inner filling 204 cools and hardens again, the two adaptive gripper mechanisms further clamp the workpiece through the clamping control mechanism, thus firmly holding the workpiece. Therefore, through the combined setting of the adaptive gripper mechanism and the clamping intelligent controller 003, the adaptive gripper mechanism can be adaptively adjusted according to the shape and size of the workpiece. The adaptive clamping body in the adaptive gripper mechanism can deform into a shape that matches the workpiece, so that it can be closely attached to the surface of the workpiece, thereby firmly and stably clamping the workpiece. Moreover, the adjustment of the adaptive gripper mechanism does not require an external magnetic field, so it will not affect the control system of the CNC machine tool, thus not only improving the machining accuracy, but also indirectly improving the machining safety.

[0036] Please see Figure 1-2 and Figure 5The connecting rod 103 passes through the outer wall of the support box 101 and is slidably connected to it. The two connecting rods 103 are respectively fixedly connected to the two support frames 201 in the two adaptive gripper mechanisms. The clamping and adjusting intelligent controller 003 is also equipped with a clamping and releasing control module. The central control unit is electrically connected to the clamping and releasing control module, and the clamping and releasing control module is electrically connected to the bidirectional cylinder 102. When the clamping mechanism drives the adaptive gripper mechanism to move, the central control unit can issue a clamping command to the clamping and releasing control module. After receiving the command, the clamping and releasing control module will start the bidirectional cylinder 102, causing the bidirectional cylinder 102 to drive the two connecting rods 103 to move towards each other and thus drive the two adaptive gripper mechanisms to move towards each other to clamp the workpiece. Similarly, by issuing a releasing command to the clamping and releasing control module through the central control unit, the bidirectional cylinder 102 can drive the two adaptive gripper mechanisms to move away in the opposite direction to remove the workpiece. After connecting the central control unit to the control system of the CNC machine tool, the operation of the fixture can be directly controlled through the control system of the CNC machine tool.

[0037] Please see Figure 4-5 A temperature sensor 207 is fixedly installed on the inner wall of the rigid outer casing 202. The clamping intelligent controller 003 is also equipped with a ringing reminder module. The temperature sensor 207 is electrically connected to the ringing reminder module and the hot melt control module. The temperature sensor 207 can detect the temperature of the hot melt filling material 204. When the temperature sensor 207 detects that the temperature of the hot melt filling material 204 is higher than its melting point, the ringing reminder module can emit a sound to remind the staff, prompting the staff to take the next step in time, thereby improving processing efficiency. At the same time, the hot melt control module can also know from the temperature sensor 207 that the temperature of the hot melt filling material 204 is higher than its melting point, so that the hot melt control module will shut off the electric heating rod 206 in time to stop heating, thereby reducing energy waste.

[0038] Please see Figure 3-4 The outer wall of the electric heating rod 206 is fitted with a wide conductive mesh plate 208. The wide conductive mesh plate 208 is made of thermally conductive material, which can improve the heating efficiency of the hot melt inner filling body 204, thereby indirectly improving the processing efficiency. The support frame 201, the rigid outer box 202, and the support cylinder 205 are all made of heat insulation material, which can reduce heat loss and thus reduce energy waste.

[0039] Please see Figure 3-6The support frame 201 is equipped with a rapid descent efficiency improvement component, which includes a cooler 401, an insulation pipe 402, a descending guide rod 403, and a spacer rod 404 matching the descending guide rod 403. The cooler 401 is embedded through the outer wall of the support frame 201. The two ends of the insulation pipe 402 are respectively sealed and fixedly connected to the support frame 201 and the rigid outer box 202. The descending guide rod 403 is fixedly connected to the wide guide mesh plate 208, and the spacer rod 404 is fixedly connected to the descending guide rod 403. Rod 404 penetrates the outer wall of the rigid outer casing 202 and is slidably and sealingly connected to it. A cooling control module is also installed in the clamping intelligent controller 003. The cooler 401 and the connecting rod 404 are both located inside the insulation pipe 402, which is made of heat-insulating material. The central control unit is electrically connected to the cooling control module, which is electrically connected to the cooler 401. A wide-beam mesh plate 208 is slidably connected to the electric heating rod 206. The wide-beam mesh plate 208 has a porous mesh structure. Both ends of the 08 are fixedly connected with elastic pull ropes 209. The other end of the elastic pull ropes 209 is fixedly connected to the inner wall of the rigid outer box 202. When the elastic outer box 203 is in close contact with the workpiece, the molten hot melt filling 204 will be compressed. When the hot melt filling 204 is compressed, it will push the wide guide plate 208, causing the wide guide plate 208 to drive the descending guide rods 403 and the spacer rods 404 to move closer to the cooler 401, causing some of the descending guide rods 403 to move towards the rigid outer box. The outer side of 202 is inserted into the inner side of the insulation pipe 402. At this time, the central control unit sends a cooling command to the cooling control module. After receiving the command, the cooling control module will start the cooler 401, so that the cooler 401 starts to cool. The cooling effect of the cooler 401 can be applied to the hot melt inner filling body 204 under the heat conduction of the guide rod 403. Therefore, by setting the fast cooling efficiency improvement component, the cooling hardening of the hot melt inner filling body 204 can be accelerated, thereby further improving the processing efficiency.

[0040] Example 2

[0041] Please see Figure 7-11Components identical or corresponding to those in Embodiment 1 are referenced in the accompanying drawings as in Embodiment 1. For simplicity, only the differences from Embodiment 1 are described below. The difference between Embodiment 2 and Embodiment 1 is that the clamping intelligent controller 003 is further provided with a detection control module and a detection analysis module. A fusion detection assembly is provided inside the support frame 201. The fusion detection assembly includes a detection adjustment box 501 embedded through the outer wall of the support frame 201. An electric telescopic rod 502 and a color recognition sensor 503 are fixedly installed inside the detection adjustment box 501. A detection linkage rod 504 is fixedly connected to the output end of the electric telescopic rod 502. A color recognition mark 505 is provided on the outer wall of the detection linkage rod 504. The detection linkage rod 504 is T-shaped. 04. The detection linkage rod 504 is slidably connected to the outer wall of the detection adjustment box 501, the outer wall of the rigid outer box 202, and the wide guide plate 208. The detection linkage rod 504 is also slidably and sealed to the outer wall of the rigid outer box 202. The color recognition mark 505 is painted with pigment and is located on the outside of the detection adjustment box 501. The temperature sensor 207 is electrically connected to the central control unit. The central control unit is electrically connected to the detection control module. The detection control module is electrically connected to the detection adjustment box 501 and the color recognition sensor 503. The color recognition sensor 503 is electrically connected to the detection analysis module. The detection analysis module is electrically connected to the ringing reminder module. The ringing reminder module has at least... It can emit three different ringtones. The ringing reminder module will emit the first ringtone. However, sometimes, due to uneven heating or a malfunction of the temperature sensor 207, the hot-melt inner filling 204 may not be completely melted. Through the setting of the melt detection component, when the temperature sensor 207 detects that the temperature of the hot-melt inner filling 204 is higher than its melting point, the central control unit will automatically issue a detection command to the detection control module. After receiving the command, the detection control module will activate the electric telescopic rod 502, causing the electric telescopic rod 502 to pull the color recognition mark 505. At the same time, the detection control module will also activate the color recognition sensor 503. When the electric telescopic rod 502 pulls the detection linkage rod 504, the detection linkage rod 504 will pass through its T If the hot-melt inner filling 204 has completely melted, the electric telescopic rod 502 can pull the detection linkage rod 504 and the wide guide plate 208, allowing the color identification mark 505 to enter the detection adjustment box 501. This enables the color recognition sensor 503 to identify the color of the color identification mark 505. The identification result of the color recognition sensor 503 will be fed back to the detection analysis module. In this case, the detection analysis module will control the ringing reminder module to emit a second ringtone. Conversely, if the hot-melt inner filling 204 has not completely melted, it will obstruct the movement of the wide guide plate 208, preventing the electric telescopic rod 502 from smoothly pulling the detection linkage rod 504 and the wide guide plate 208.This prevents the color recognition sensor 503 from recognizing the color of the color mark 505. In this case, the detection and analysis module controls the ringing reminder module to emit a third ringtone. Therefore, through the settings of the clamping intelligent controller 003 and the melting detection component, the melting detection component can detect and verify whether the hot-melt inner filling 204 has completely melted. The melting detection component can also feed back the detection and verification results to the operator through the ringing reminder module. If the ringing reminder module emits a second ringtone, the operator can proceed with subsequent operations directly. If the ringing reminder module emits a second ringtone, it is necessary to continue heating the hot-melt inner filling 204. This not only further improves the processing accuracy but also enhances the intelligence of the fixture and indirectly improves processing efficiency, greatly increasing practicality.

[0042] Please see Figure 10-11 A light source 506 is fixedly installed inside the detection adjustment box 501. The central control unit is electrically connected to the light source 506. When the central control unit sends a detection command to the detection control module, it will also turn on the light source 506 to illuminate the inside of the detection adjustment box 501. This will help the color recognition sensor 503 to recognize the color mark 505, thereby improving the accuracy of the detection and verification functions of the fusion detection component.
