Description

Technical Field

[0001] This application relates to the technical field of machining, and more specifically, to an automated clamping device. Background Technology

[0002] In the field of mechanical manufacturing, tool regrinding is a critical process, and its quality directly affects the accuracy of subsequent machining and the surface finish of the workpiece. Tool regrinding typically requires the use of a four-axis linkage system in conjunction with a hydraulic tool holder. The four-axis linkage system supports the precise positioning and rotational control of tools with complex curved surfaces, while the hydraulic tool holder, as the main component for fixing the tool, provides stable and reliable clamping force. By adjusting the angles of the four axes, complex geometric repairs or cutting edge treatments can be achieved.

[0003] Currently, most processes still rely on manual loading and unloading of tools one by one. Special wrenches are used to tighten the screws on the hydraulic tool holder to fix the tools, or to loosen the screws on the hydraulic tool holder to remove the tools. Because loading and unloading tools is cumbersome, frequent human-machine interaction reduces overall production efficiency. Secondly, it increases the labor intensity of operators, and it is easy for human factors to cause error accumulation, which in turn affects the pass rate of tool regrinding. Utility Model Content

[0020] The operator loads materials onto a pallet. A rotating mechanism drives the first clamping mechanism to rotate, aligning it with the pallet for easy gripping of the materials. After gripping the materials, the rotating mechanism controls the first clamping mechanism to rotate until it aligns with the second clamping mechanism, ensuring their angles are consistent. The spindle then drives the material handling device towards the four-axis linkage device, allowing the other end of the material to contact and be clamped by the second clamping mechanism. The first clamping mechanism then releases the material. The machine starts processing the material, and after processing, the first clamping mechanism... The clamping mechanism clamps the material, and then the second clamping mechanism releases it. The processed material is then removed through the first clamping mechanism, thus completing one processing cycle. Because the angles of the four-axis linkage device are different, the material handling device can adjust the rotating mechanism to match the angle of the four-axis linkage device according to the angle required in the actual processing. The first and second clamping mechanisms can automatically handle material handling, effectively reducing the workload of operators in handling material handling and improving the automation level of clamping, thereby increasing production efficiency. Furthermore, automated clamping reduces the accumulation of errors caused by human factors, thereby improving the pass rate of material processing. Attached Figure Description

Detailed Implementation

[0031] The present application will be further described in detail below with reference to the accompanying drawings.

[0032] This application provides an automated clamping device that can effectively reduce the labor intensity of operators, improve production efficiency, and increase the pass rate of material processing.

[0033] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings.

When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by the present application.

[0034] The terms "first," "second," "third," "fourth," etc., used in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover a non-exclusive inclusion; for example, a process, method, system, product, or apparatus that comprises a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to such processes, methods, products, or apparatus.

[0035] Please see Figure 1 This is one embodiment of the automated clamping equipment in this application. The automated clamping equipment includes a machine base (not shown in the figure), a material handling device 100, and a four-axis linkage device 200. The machine base is equipped with a main spindle and a tray for loading materials. The materials are vertically loaded into the tray. The material handling device 100 is located on the main spindle of the machine base and is used to pick up and place materials. The four-axis linkage device 200 is located on the machine base and is situated to one side of the material handling device 100. The four-axis linkage device 200 is used to clamp the materials for subsequent processing. It can be understood that the materials can also be placed directly on the machine base.

[0036] Please see Figure 2 and Figure 3The material handling device 100 includes a rotating mechanism 110 and a first clamping mechanism 120. The rotating mechanism 110 is connected to the machine spindle and drives the first clamping mechanism 120 to rotate so that the first clamping mechanism 120 is aligned with the pallet for clamping materials on the pallet. It can be understood that the operator loads materials onto the pallet, and the rotating mechanism 110 drives the first clamping mechanism 120 to rotate, aligning the first clamping mechanism 120 with the pallet, facilitating the clamping mechanism 120 to clamp the materials in the pallet. After the first clamping mechanism 120 clamps the materials, the rotating mechanism 110 controls the first clamping mechanism 120 to rotate until the angle between the first clamping mechanism 120 and the four-axis linkage device 200 is consistent, thereby enabling the four-axis linkage device 200 to contact and clamp the materials clamped on the first clamping mechanism 120. Since the angles of the four-axis linkage device 200 are different, the material handling device 100 can adjust the rotating mechanism 110 arbitrarily according to the angle required in the actual processing to adapt to the angle of the four-axis linkage device 200. Since the first clamping mechanism 120 can automatically pick up and place materials, it effectively reduces the workload of operators in picking up and placing materials, improves the automation level of clamping, and thus improves production efficiency. Secondly, since automated clamping reduces the accumulation of errors caused by human factors, it improves the pass rate of material processing.

[0037] Please refer to the following: Figure 4 The rotating mechanism 110 includes a mounting base 111 fixedly connected to the machine tool spindle, a drive assembly 112, and a rotating component 113. The rotating component 113 is located in the central area of ​​the mounting base 111 and is rotatably mounted on the mounting base 111. The drive assembly 112 is mounted on the mounting base 111 and drives the rotating component 113 to rotate. The rotation of the rotating component 113 drives the first clamping mechanism 120 to rotate synchronously to realize the angle adjustment of the first clamping mechanism 120, so that the first clamping mechanism 120 can be aligned with the tray or the four-axis linkage device 200. Specifically, the drive assembly 112 includes a first sliding member 1121 and a second sliding member 1122 slidably disposed on the mounting base 111. The first sliding member 1121 and the second sliding member 1122 are respectively disposed on both sides of the rotating member 113, and the first sliding member 1121 and the second sliding member 1122 move in opposite directions. The first sliding member 1121 and the second sliding member 1122 are provided with racks on their end faces facing the rotating member 113. The rotating member 113 is configured as a rotating gear, and the rotating gear meshes with the first sliding member 1121 and the second sliding member 1122.

[0038] Please see Figure 4In this embodiment, the mounting base 111 is provided with a receiving cavity 1111, which includes a first chamber for accommodating a first sliding member 1121, a second chamber for accommodating a second sliding member 1122, and a third chamber for accommodating a rotating member 113. The first chamber and the second chamber are connected to the third chamber. The first sliding member 1121 is slidably connected to the inner wall of the first chamber, and the second sliding member 1122 is slidably connected to the inner wall of the second chamber. One end of the mounting base 111 is provided with an air inlet pipe 1112 for communicating with external equipment and a solenoid valve (not shown). There are two air inlet pipes 1112, which are respectively provided for the first chamber and the second chamber. The solenoid valve is used to control the entry and exit of compressed gas into the first chamber and the second chamber. Understandably, when the rotating mechanism 110 needs to drive the first clamping mechanism 120 to rotate, the solenoid valve controls the compressed gas to enter and exit the first chamber and the second chamber, so that the first sliding member 1121 and the second sliding member 1122 move in opposite directions. At this time, the first sliding member 1121 and the second sliding member 1122, which move in opposite directions, cause the rotating member 113 to rotate under the cooperation of the gear and rack. The rotating member 113 cooperates with the first sliding member 1121 and the second sliding member 1122 to convert the linear motion of the first sliding member 1121 and the second sliding member 1122 into the rotational motion of the rotating member 113. In this application, the drive assembly 112, through the gear and rack transmission between the rotating component 113 and the first sliding component 1121 and the second sliding component 1122, can ensure high positional accuracy and speed stability of the first clamping mechanism 120 during rotation. At the same time, it can transmit large torque and has good rigidity, maintaining stable operation under heavy load conditions. This results in high positioning accuracy and strong stability of the first clamping mechanism 120 when aligning with the pallet or the four-axis linkage device 200, improving the success rate of material clamping or transfer, thereby further improving production efficiency.

[0039] Furthermore, in order to precisely control the rotation angle of the rotating component 113 and ensure accurate positioning when the rotating component 113 rotates to align with the four-axis linkage device 200, two limiting components 114 are rotatably provided at one end of the mounting base 111. The two limiting components 114 are respectively provided for the first sliding component 1121 and the second sliding component 1122, and are used to limit the movement range of the first sliding component 1121 and the second sliding component 1122. The limiting component 114 is provided with a graduated thread and can move axially to adjust its position. The spacing of the graduated thread is the same as the tooth spacing of the rotating gear to control the rotation angle of the rotating component 113. In this embodiment, the limiting member 114 is preferably a limiting screw. The limiting member 114 is rotatably connected to the mounting base 111 through a graduated thread, which reduces the possibility that the position of the limiting member 114 after adjustment may be displaced due to vibration or load changes. The limiting member 114 can move axially through the graduated thread to adjust the length of the limiting member 114 extending into the first chamber and the second chamber. Therefore, by adjusting the position of the two limiting members 114, different stop points can be flexibly set to limit the movement range of the first sliding member 1121 and the second sliding member 1122. It is understandable that the same scale thread pitch as the tooth pitch of the rotating part 113 means that for every scale movement of the limiting part 114, the position change of the limiting part 114 is equivalent to one tooth pitch of the rotating part 113, which in turn causes the rotating part 113 to rotate by the angle of one tooth. By adjusting the position of the limiting part 114, the rotation angle of the rotating part 113 can be precisely controlled, ensuring that the rotating part 113 stops accurately at the required position. This allows the first clamping mechanism 120 to adapt to different alignment requirements. Operators can make precise adjustments according to the scale without the need for complex measuring tools, thus improving the convenience and accuracy of operation.

[0040] Please see Figure 3 and Figure 5The first clamping mechanism 120 rotates via the rotating component 113. Specifically, the first clamping mechanism 120 includes a mounting assembly 121, a driving component 122, and a clamping assembly 123. The mounting assembly 121 rotates synchronously with the rotating component 113. The driving component 122 is disposed on the mounting assembly 121 and controls the clamping assembly 123 to close to clamp the material, or controls the clamping assembly 123 to open to release the material. In this embodiment, the mounting assembly 121 includes a mounting plate 1211 and a receiving cylinder 1212. The mounting plate 1211 is parallel to the rotating component 113 and is fixedly connected to the rotating component 113. The rotating component 113 rotates synchronously with the mounting plate 1211, the driving component 122, and the clamping assembly 123, thereby achieving overall angle adjustment of the clamping assembly 123. The receiving cylinder 1212 is vertically disposed and fixed to the mounting plate 1211. The rotation of the mounting plate 1211 synchronously drives the receiving cylinder 1212 to rotate. The inner wall of the receiving cylinder 1212 is provided with multiple detachable rotating shafts 1234. The driving component 122 and the clamping assembly 123 are both located inside the receiving cylinder 1212. The driving component 122 is located above the clamping assembly 123 and is fixedly installed on the top of the receiving cylinder 1212. The clamping assembly 123 is rotatably mounted on the rotating shaft 1234 of the receiving cylinder 1212, which facilitates direct contact with the end of the material and facilitates clamping. The driving component 122 is preferably a cylinder.

[0041] Furthermore, the clamping assembly 123 includes a plurality of grippers 1231 evenly and spaced along the circumference. All grippers 1231 are housed within the receiving cylinder 1212, and move towards the center of the receiving cylinder 1212 to clamp the material. The design of multiple grippers 1231 provides a more uniform pressure distribution, reducing the risk of material damage due to excessive localized force. Secondly, the evenly distributed grippers 1231 on the circumference improve the equipment's balance, avoiding skewness caused by unilateral force application. Specifically, this embodiment includes three grippers 1231, and three corresponding rotating shafts 1234, forming a triangle. Each gripper 1231 includes a connecting portion 12311 and a clamping portion 12312. The length direction of the connecting portion 12311 is perpendicular to the length direction of the clamping portion 12312, and one end of the connecting portion 12311 is rotatably connected to the receiving cylinder 1212 via a corresponding rotating shaft 1234.

[0042] To simultaneously control multiple grippers 1231, the first clamping mechanism 120 also includes a pull claw 124 and a positioning pin 125 disposed within the receiving cylinder 1212. The pull claw 124 is located between the driving member 122 and the clamping assembly 123, with the pull claw 124 positioned at the output end of the driving member 122. The positioning pin 125 is located at the other end of the connecting portion 12311, and the pull claw 124 is fixed to the connecting portion 12311 by the positioning pin 125. The driving member 122 drives the pull claw 124 to move up and down, so that the connecting portion 12311 moves up and down synchronously with the pull claw 124 under the action of the positioning pin 125, thereby driving the clamping portion 12312 to rotate around the pivot 1234 to clamp or release materials. Understandably, when material needs to be gripped, the drive unit 122 drives the pull claw 124 to move downwards, and the pull claw 124 moves downwards synchronously. At the same time, the connecting part 12311 of the gripper 1231 moves downwards synchronously with the pull claw 124 under the action of the positioning pin 125. At this time, the gripping part 12312 of the gripper 1231 rotates around the pivot 1234 so that the gripping part 12312 moves toward the central axis of the gripping assembly 123 to clamp the material. Conversely, when material needs to be released, the drive unit 122 drives the pull claw 124 to move upwards, and the pull claw 124 moves upwards synchronously. At the same time, the connecting part 12311 of the gripper 1231 moves downwards synchronously with the pull claw 124 under the action of the positioning pin 125. At this time, the gripping part 12312 of the gripper 1231 rotates around the pivot 1234 so that the gripping part 12312 moves away from the central axis of the gripping assembly 123 to release the material.

[0043] Please see Figure 5 To improve the clamping degree of the material, the clamping part 12312 is provided with a clamping block 1232 and a connecting rod 1233 facing the end face of the material. The clamping block 1232 includes a mounting part 12321 and a pressing part 12322. The mounting part 12321 and the pressing part 12322 are fixedly connected. The connecting rod 1233 passes through the mounting part 12321 and the clamping part 12312 so that the mounting part 12321 is detachably connected to the clamping part 12312. There is a gap between the mounting part 12321 and the clamping part 12312 so that the pressing part 12322 can rotate. Understandably, the clamping block 1232 adopts a detachable design, which allows the gripper 1231 to adapt to the material size when changing to materials of different diameters, or to facilitate the replacement of the clamping block 1232 if it is damaged. This improves the clamping tightness of the gripper 1231 and reduces the probability of the material slipping out of the clamping assembly 123. Since the mounting part 12321 and the clamping part 12312 are connected by the connecting rod 1233, and there is a gap between the mounting part 12321 and the clamping part 12312, the pressing part 12322 can rotate slightly after being subjected to force to achieve the effect of automatic fine adjustment of the angle, so that the pressing part 12322 can contact the material as much as possible to clamp the material.

[0044] Please see Figure 6 Furthermore, the end face of the pressing part 12322 facing the material is provided with an arc surface 12323. The arc surface 12323 is used to adapt to the outer peripheral wall of the material to increase the contact area with the material. The increased contact area helps to disperse the pressure between the pressing part 12322 and the material, preventing damage to the material due to local stress concentration. Secondly, the larger contact range improves the effect of friction, thereby strengthening the clamping force and making the entire equipment more stable and reliable in operation. Moreover, when dealing with materials of various shapes, especially those with large curvature changes, the design of the pressing part 12322 with the arc surface 12323 shows greater adaptability, meeting diverse production needs without the need for frequent changes of special tools.

[0045] Please see Figure 7 The four-axis linkage device 200 includes a second clamping mechanism 210, a bracket 220, and a four-axis body 230. The bracket 220 is fixedly connected to the machine tool. The second clamping mechanism 210 is disposed on the four-axis body 230. The four-axis body 230 is fixedly disposed on the bracket 220. The rotating mechanism 110 drives the first clamping mechanism 120 to rotate so that the first clamping mechanism 120 is aligned with the second clamping mechanism 210. The second clamping mechanism 210 is used to clamp the material from the first clamping mechanism 120. Understandably, after the first clamping mechanism 120 clamps the material, the rotating mechanism 110 controls the first clamping mechanism 120 to rotate until it is aligned with the second clamping mechanism 210 to ensure that the angles of the first clamping mechanism 120 and the second clamping mechanism 210 are consistent. The machine spindle drives the material handling device 100 to move toward the four-axis linkage device 200 so that the other end of the material can contact and be clamped by the second clamping mechanism 210. Then the first clamping mechanism 120 releases the material. The machine starts to process the material. After the material is processed, it is clamped by the first clamping mechanism 120 and then released by the second clamping mechanism 210. The processed material is removed by the first clamping mechanism 120, which means that one processing cycle is completed.

[0046] In this embodiment, the second clamping mechanism 210 has the same structure as the first clamping mechanism 120, so it will not be described again. The four-axis body 230 is configured as a horizontal four-axis, an angled four-axis, or a vertical four-axis. The central axis of the second clamping mechanism 210 is consistent with the central axis of the four-axis body 230. Since the angles of the four-axis body 230 are different, the material handling device 100 can drive the first clamping mechanism 120 to rotate through the rotating mechanism 110. The angle can be adjusted arbitrarily according to the angle required in the actual processing, so that the first clamping mechanism 120 and the second clamping mechanism 210 are precisely aligned to complete the material transfer, achieve the effect of automatic material clamping, and expand the applicability of the equipment.

[0047] The above-described embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this application.
