Specific implementation mode

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0019] Referring to Figures 1 - 4 , a milling cutter device for processing rubber ring molds includes a clamping seat 1. The inner wall of the bottom end of the clamping seat 1 is threadedly installed with the driving end of the milling machine. The rotation of the clamping seat 1 is realized by the rotation of the driving end of the milling machine. A telescopic adjustment mechanism 2 is arranged on the top of the clamping seat 1. The telescopic adjustment mechanism 2 includes a telescopic rod 3. An adjustment block 4 is installed on the top of the clamping seat 1. An insertion slot 5 is opened on the surface of the adjustment block 4. The inner wall of the insertion slot 5 is slidably inserted with the surface of the telescopic rod 3.

[0020] One end of the telescopic rod 3 is fixedly installed with a mounting seat 6. The top of the mounting seat 6 is threadedly connected with a cutter clamping block 7 by screws. A clamping groove 8 is opened at the top end of the cutter clamping block 7. A milling cutter 9 is inserted into the inner wall of the clamping groove 8.

A set screw 11 is threadedly connected to the inner wall of the locking hole 10. One end of the set screw 11 is pressed against the surface of the milling cutter 9.

[0021] Specifically implemented in this way, through the design of the clamping groove 8 at the top end of the cutter clamping block 7 and the set screw 11, it can ensure that the milling cutter 9 is firmly fixed on the clamping block, avoiding the loosening of the cutter during the processing, and improving the stability and safety of the processing; when the cutter needs to be replaced, only need to loosen the set screw 11, and the old cutter can be quickly taken out and a new cutter can be inserted, simplifying the cutter replacement process.

[0022] The telescopic adjustment mechanism 2 further includes a drive cavity 12 opened inside the clamping seat 1. An electric push rod 13 is fixedly installed on one inner wall of the drive cavity 12. The telescopic end of the electric push rod 13 is fixedly installed with a drive piston 14. The surface of the drive piston 14 is slidably inserted into the inner wall of the drive cavity 12 through a sealing ring. Hydraulic oil is arranged inside the space formed by the right side of the drive piston 14 and the relative drive cavity 12.

[0023] Specifically, the use of the electric push rod 13 enables the telescopic adjustment of the tool device to be achieved through electric control, improving the degree of automation, reducing manual operation, and enhancing production efficiency. The electric push rod 13 can perform precise telescoping according to programming or remote control instructions, thereby achieving precise control of the tool position and improving machining accuracy. The use of the drive piston 14 and hydraulic oil forms a hydraulic system. Through the pressure transmission of the hydraulic oil, the movement of the drive piston 14 can be made smoother, so that the telescoping of the tool is more uniform and stable.

[0024] A chute 15 is opened at the bottom end of the telescopic rod 3. The inner wall of the chute 15 is slidably inserted into the surface of the boss on the inner bottom wall of the insertion slot 5. An adjustment cavity 16 is further opened inside the adjustment block 4, and the adjustment cavity 16 is located inside the boss on the inner bottom wall of the insertion slot 5.

[0025] Specifically, the sliding insertion design of the chute 15 and the boss allows the telescopic rod 3 to make precise left and right movements inside the adjustment block 4, thereby realizing the adjustment of the position of the milling cutter 9 and ensuring the machining of different positions. The adjustment cavity 16 is located inside the boss, enabling the telescopic rod 3 to be adjusted within a large range to meet the processing requirements of rubber ring molds of different sizes.

[0026] A spring 17 is fixedly installed on the left inner wall of the adjustment cavity 16. The right end of the spring 17 is fixedly installed with an adjustment piston 18. The peripheral surface of the adjustment piston 18 is slidably inserted into the inner wall of the adjustment cavity 16 through a sealing ring.

[0027] Specifically, the function of the spring 17 enables the adjustment piston 18 to automatically adjust according to the position of the telescopic rod 3, thereby realizing the automatic compensation of the tool position and maintaining the machining accuracy. The spring 17 can provide uniform pressure to ensure the smooth movement of the adjustment piston 18 in the adjustment cavity 16 and reduce the machining errors caused by uneven pressure.

[0028] A sliding groove 19 is opened on the right end surface of the adjustment cavity 16. A connecting rod 20 is slidably inserted into the inner wall of the sliding groove 19. One end of the connecting rod 20 is fixedly installed on the surface of the adjustment piston 18, and the other end of the connecting rod 20 is fixedly installed on the right inner wall of the chute 15. The surface of the connecting rod 20 is also slidably sealed with the inner wall of the sliding groove 19 through a sealing ring.

[0029] Specifically, it is implemented as follows. The connecting rod 20 transmits the movement of the adjusting piston 18 to the sliding groove 15, realizing the linkage between the adjusting piston 18 inside the adjusting cavity 16 and the external telescopic rod 3, and ensuring the synchronization of the adjustment. The hydraulic oil inside generates oil pressure to push the connecting rod 20 to slide inside the adjusting cavity 16, and then realizes the left and right movement of the telescopic rod 3 on the surface of the adjusting block 4, thereby adjusting the diameter size of rubber rings of different sizes. When processing rubber rings with a mold, the size can be automatically adjusted for rapid processing, improving the working effect.

[0030] A flow hole 21 is provided in the inner bottom wall of the space formed between the right end of the adjusting piston 18 and the adjusting cavity 16. The bottom end of the flow hole 21 is fixedly communicated with the inner top wall of the space formed between the right side of the driving piston 14 and the relative driving cavity 12.

[0031] Specifically, it is implemented as follows. The setting of the flow hole 21 allows the hydraulic oil to flow between the adjusting piston 18 and the driving piston 14, forming a hydraulic transmission system, thereby realizing the hydraulic drive of the adjusting piston 18.

[0032] By setting the telescopic adjustment mechanism 2, the automatic design can automatically adjust the position of the telescopic rod 3 according to the diameter size of the rubber ring without manual intervention, greatly improving the automation degree of processing. Since the automatic adjustment can accurately control the position of the tool, the groove size accuracy of the processed rubber ring can be guaranteed, reducing the rejection rate. The traditional multi-axis movement processing method requires complex operations and adjustments. However, in this device, the movement of the telescopic rod 3 is automatically controlled to adjust the processing position according to the diameter size of the rubber ring. Under the rotary motion processing, the operation is more convenient, and the dependence on the multi-axis control system can be reduced, lowering the equipment cost and maintenance cost. Utilizing the rotary motion of the driving end of the milling machine, the tool processes on the surface of the mold to form a rubber ring mold, which can quickly complete the manufacture of the rubber ring mold, improving the production speed.

[0033] Working principle: During operation, when taking the mold core and processing the rubber ring size on the surface, the electric push rod 13 is used for telescopic movement to control the internal hydraulic power to be transmitted through the flow hole, so that the oil pressure inside the adjusting cavity 16 increases or decreases. When processing a rubber ring with a large diameter size, control the connecting rod 20 to retract inside the adjusting cavity 16, thereby driving the telescopic rod 3 to move leftward, increasing its diameter. Under the rotary motion of the driving end of the milling machine, drive the milling cutter 9 of the milling machine to perform circular rotary processing on the surface of the mold for the large-diameter rubber ring size;

[0034] After the processing of the rubber ring groove with a large diameter size is completed, the moving position of the telescopic rod 3 is adjusted according to the rubber ring with a small diameter size. Further, a rubber ring groove with a small diameter is machined inside the rubber ring groove with a large diameter, so as to form grooves with multiple rubber ring sizes at the top of the mold, and the large ring and the small ring are concentrically arranged. Thus, rubber rings with different sizes can be generated after the mold is processed and formed. When processing the rubber ring groove of the device, only the diameter size needs to be adjusted, and then a rotational movement is carried out to process the circular groove, avoiding the existing use of a multi-axis system to achieve circular processing. The processing equipment is simple and suitable for the processing of most small factories, with low costs.

[0035] The above are only the preferred specific embodiments of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
