[0025] 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.

[0026] like Figures 1 to 4 As shown, this utility model provides an automated multi-position fixing device for a chuck, including a base plate 1, a base 2, a chuck body 3, a fixing unit 4, a fixing groove 5, a fixing mechanism 7, an automated drive mechanism 8, and a horizontal adjustment mechanism 9.

[0027] The base 2 provides stable support for the entire device and is movably connected to the base plate 1. The bottom of the base plate 1 is equipped with shock-absorbing pads, which can effectively reduce the vibration generated during the operation of the device and ensure the stability of processing. The chuck body 3 is located above the base 2, and its surface has three fixing slots 5. Fixing units 4 are set at the positions where the fixing slots 5 are opened. The fixing units 4 can slide in the fixing slots 5 opened in the chuck body 3 and are driven by an external cylinder to clamp and fix the workpiece.

[0028] The fixing mechanism 7 is set on the upper surface of the base 2 and includes an electric push rod 71 and a clamping finger 72. The electric push rod 71 is installed on the upper surface of the base 2, and the clamping finger 72 is installed on the extended end of the electric push rod 71. The extension and retraction of the electric push rod 71 drives the clamping finger 72 to move, further strengthening the fixing of the workpiece.

[0029] The automated drive mechanism 8 is located inside the base 2 and includes a rotary drive motor 81 and a transmission component 82. The rotary drive motor 81 is installed inside the base 2, and its output shaft is connected to the chuck body 3 through the transmission component 82, which can drive the chuck body 3 to rotate and realize automated processing operations.

[0030] It should be noted that the transmission component 82 adopts gear transmission, which has the advantages of accurate transmission ratio and high transmission efficiency.

[0031] The clamping surface of the clamping finger 72 is provided with a wear-resistant rubber layer 73, and the clamping surface of the wear-resistant rubber layer 73 is provided with anti-slip teeth, which can increase the friction between the clamping finger 72 and the workpiece, improve the fixing effect, and at the same time, the wear-resistant rubber layer 73 can also prevent the workpiece surface from being damaged.

[0032] The clamping surface of the clamping fingers 72 is also equipped with a pressure sensor. The pressure sensor is connected to an external controller and can monitor the clamping pressure of the clamping fingers 72 on the workpiece in real time and feed the data back to the external controller so as to adjust the clamping force according to the actual situation and ensure the stability and safety of the fixation.

[0033] The inner wall of the through hole on the surface of the chuck body 3 is provided with a removable positioning bushing 6. The positioning bushing 6 is designed with various specifications according to the inner hole size of different workpieces. The positioning bushing 6 is screwed to the chuck body 3 through a screw sleeve, which can easily replace the positioning bushing 6 to meet the fixing requirements of workpieces of different specifications.

[0034] like Figures 1 to 4 As shown, the horizontal adjustment mechanism 9 is located between the base plate 1 and the base 2, and includes adjusting bolts 91, a moving block 92, and a guide groove 93. Multiple adjusting bolts 91 are installed inside the base plate 1. One end of each adjusting bolt 91 is inserted into the base plate 1 and rotatably connected to it. The moving block 92 is threaded onto the surface of each adjusting bolt 91 and slides within a groove on the surface of the base plate 1. A triangular guide groove 93 is provided on the bottom surface of the base 2 corresponding to the position of the moving block 92. One end of the moving block 92 abuts against the guide groove 93 and has an oblique cut. By rotating the adjusting bolts 91, the moving block 92 is moved, thereby adjusting the horizontal position of the base 2.

[0035] One end of the adjusting bolt 91 is equipped with a scale 94, which facilitates accurate adjustment of the horizontal position of the base 2 and improves the precision of the adjustment.

[0036] Working principle and process: When using this automated multi-position fixing device for chucks, firstly, select a suitable positioning bushing 6 according to the size and shape of the workpiece to be processed, and install it on the inner wall of the through hole on the surface of the chuck body 3 using a screw sleeve. Then, place the workpiece on the chuck body 3, so that the inner hole of the workpiece mates with the positioning bushing 6, and start the external cylinder to drive the fixing unit 4 to slide in the fixing groove 5, thus initially clamping the workpiece.

[0037] Next, the electric push rod 71 is activated, causing the gripper fingers 72 to extend and clamp the workpiece. At this time, the pressure sensor on the gripping surface of the gripper fingers 72 monitors the clamping pressure in real time and transmits the data to the external controller. If the pressure value is not within the preset range, the external controller automatically adjusts the thrust of the electric push rod 71 until the pressure is appropriate.

[0038] According to the processing requirements, by rotating the adjusting bolt 91, the moving block 92 is moved within the guide groove 93 to adjust the horizontal position of the base 2 and the chuck body 3. Observe the scale 94 to ensure that the device is in a horizontal state. Finally, start the rotary drive motor 81, which drives the chuck body 3 to rotate through the transmission component 82 to perform the workpiece processing operation.

[0039] If it is necessary to change the workpiece during the processing, first turn off the rotary drive motor 81 to stop the rotation of the chuck body 3, then control the electric push rod 71 to retract the clamping finger 72, turn off the external cylinder, and release the fixing unit 4 so that the workpiece can be taken out. Repeat the above operation after replacing the new workpiece.

[0040] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0041] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
