Technical Field

[0001] This invention relates to the field of metal cutting technology, and in particular to a cutting device for processing metal parts. Background Technology

[0002] A cutting device for metal parts processing is a special equipment that separates metal materials by physical means to obtain workpieces of the required size or shape. After fixing the accessories, the workpiece can be cut and separated at fixed points by moving a high-speed rotating saw blade, thereby processing the required parts.

[0003] The cutting device currently in use is not suitable for the rapid adjustment of workpiece position by a circular saw, the multi-angle adjustment and fixation of workpiece position, and the flexible readjustment of moving parts during workpiece fixation. Summary of the Invention

[0004] In view of the above, the present invention addresses the shortcomings of the prior art by providing a cutting device for processing metal parts.

[0005] This invention provides a cutting device for processing metal parts, specifically comprising: a main platform, a traveling frame fixedly mounted on the top of the main platform, a guide frame fixedly mounted above the middle of the traveling frame, a cutter slidably mounted on a guide rail outside the guide frame, a cutting motor fixedly mounted outside the cutter, and a circular saw driven by the cutting motor rotatably mounted inside the cutter; a positioning table, a rotating support fixedly mounted on the bottom of the positioning table, a hollow shaft integrally mounted in the middle of the bottom of the rotating support; a cross groove opened in the middle of the upper part of the positioning table; and two sets of cross sections opened in the middle of the positioning table. The system consists of a U-shaped channel with two sets of guide rods fixedly installed at the bottom inside. U-shaped clamps slide on the outside of the guide rods, with the top of the U-shaped clamps extending out of the channel. Side clamps are fixedly installed on both sides of the positioning platform, and hydraulic telescopic cylinders are fixedly installed above each side clamp. A transmission worm gear is rotatably mounted on the lower exterior of the hollow shaft in conjunction with a bearing. The transmission worm gear has a hollow structure. The lower exterior of the hollow shaft has a hexagonal structure, and an inner ring is fixedly installed on the lower exterior of the hollow shaft, located inside the transmission worm gear. A base frame is fixedly installed at the bottom of the main platform, and two sets of fluid channels are fixedly installed on the top of the base frame.

[0006] Optionally, two sets of limiting blocks are fixedly installed on the top of the main structure platform, and a blocking block is fixedly installed on the bottom of the turntable. The blocking block can contact the limiting blocks during rotation, and the limiting blocks restrict the rotational movement of the blocking block to no more than 90 degrees. A worm gear is rotatably installed on the bottom of the main structure platform, and the worm gear is connected to the transmission worm wheel. A steering motor is fixedly installed on the bottom of the main structure platform, and the steering motor is connected to the worm gear.

[0007] Optionally, a lead screw block is fixedly installed on the outside of the guide frame, and a travel screw is rotatably installed above the travel frame, with the travel screw threadedly connected to the lead screw block; a travel motor is fixedly installed on the outside of the travel frame, and the travel motor is drivenly connected to the travel screw.

[0008] Optionally, a clamping screw is rotatably installed inside the lower part of each through groove, and a clamping motor is fixedly installed on the outside of each positioning chuck. The clamping motor is connected to the clamping screw via a transmission, and the clamping screw is connected to the U-shaped clamp thread.

[0009] Optionally, a positioning ring is fixedly provided on the outside of the hollow shaft, and five sets of positioning grooves are equally spaced outside the positioning ring, with the two furthest sets of positioning grooves staggered by 90 degrees.

[0010] Optionally, each of the hydraulic telescopic cylinders is externally connected to a solenoid valve A. Each solenoid valve A is externally connected to two sets of solenoid valves B, which pass through the internal branches of the hollow shaft. Each set of solenoid valves B is connected to two sets of liquid passages via a steel wire hose.

[0011] Optionally, the transmission worm gear has six sets of worm gear teeth integrally arranged inside, and six sets of propulsion teeth integrally arranged outside the inner ring. The propulsion teeth and worm gear teeth are arranged alternately, and springs are fixedly arranged between the propulsion teeth and the worm gear teeth.

[0012] Optionally, a miniature electric cylinder is fixedly installed at the bottom of the main platform, and a positioning pin is fixedly installed at the telescopic end of the miniature electric cylinder.

[0014] The beneficial effects are as follows:

[0015] This invention employs a dual fixing method combining mechanical clamping and hydraulic assistance. First, the workpiece is initially clamped by a U-shaped clamp and a clamping screw, and then further fixed by a hydraulic telescopic cylinder to ensure that the workpiece does not move during cutting. Moreover, when adjusting the position, there is no need to disassemble the workpiece. By simultaneously controlling the contraction of the hydraulic telescopic cylinder and the movement of the U-shaped clamp, the position can be finely adjusted while maintaining the stability of the workpiece, making the operation convenient and efficient.

[0016] This invention uses a worm gear and worm wheel to drive the positioning table to rotate, and with the help of a limit block, the angle adjustment range is controlled within 90 degrees, fundamentally avoiding the problem of connecting wires and oil pipes getting tangled. After the angle is adjusted to the correct position, a positioning pin is inserted into the positioning slot to lock the position, and the positioning accuracy is better than that of electronic positioning methods. At the same time, the spring between the inner ring and the transmission worm wheel can automatically offset the transmission error, further improving the accuracy of angle positioning and meeting the cutting needs of different angles.

[0017] This invention can automatically complete the entire cutting process. After the cutting motor is started, the travel motor drives the lead screw to drive the cutter to move automatically, and the rotating circular saw achieves the cutting. After a single cutting is completed, the cutter can automatically reset. After the workpiece is replaced, the next cutting can be started without frequent manual intervention. This design reduces the intensity of manual operation and reduces the error caused by manual operation, and significantly improves efficiency in batch processing scenarios.

Two sets of oil pumps 11 are connected to the outside of the oil tank 10, and the two sets of oil pumps 11 are respectively connected to the bottom of the two sets of liquid passages 9 by pipes.

[0040] Workpiece fixing operation

[0041] Initial placement: Place the workpiece to be processed above the positioning table 3 to ensure that the workpiece is initially centered.

[0042] Mechanical clamping and fixing:

[0043] Start the clamping motor 306, and the motor drives the clamping screw 305 to rotate;

[0044] The clamping screw 305 drives the two sets of U-shaped clamps 304 to move synchronously, so that the two sets of U-shaped clamps 304 come closer to each other until the workpiece is clamped, thus completing the mechanical fixation.

[0045] Hydraulic assisted fixation:

[0046] The lower oil pump 11 is responsible for supplying oil to the system, and the upper oil pump 11 is responsible for returning oil from the system.

[0047] Open the solenoid valve A502 on the outside of the hydraulic telescopic cylinder 501, and at the same time open the solenoid valve B503 above the inner liquid passage 9.

[0048] Oil is injected into the hydraulic telescopic cylinder 501 using the lower oil pump 11, causing the hydraulic telescopic cylinder 501 to open and further fix the workpiece.

[0049] Through a preset control program, the hydraulic telescopic cylinder 501 and the U-shaped clamp 304 work together to precisely center and fix the workpiece.

[0050] Contraction control:

[0051] Close the solenoid valve B503 above the inner liquid passage 9, and at the same time open the solenoid valve B503 above the outer liquid passage 9.

[0052] Start the upper oil pump 11 to pump the hydraulic oil in the hydraulic control telescopic cylinder 501 back to the oil tank 10, thereby realizing the retraction of the hydraulic control telescopic cylinder 501.

[0053] Coordinated position adjustment:

[0054] The retraction amplitude of the hydraulic telescopic cylinder 501 and the moving distance of the U-shaped clamp 304 are synchronously controlled.

[0055] While maintaining a stable clamping state, the position of the workpiece can be finely adjusted or moved.

[0056] Cutting preparation: Ensure that the workpiece has been centered and fixed through the above steps.

[0057] Example 2: Cutting execution:

[0058] Start the cutting motor 203, which drives the circular saw 204 to rotate at high speed;

[0059] Start the travel motor 207, and the motor drives the travel screw 206 to rotate;

[0060] The lead screw 206 drives the lead screw block 205 to move, and the lead screw block 205 synchronously drives the cutter 202 to move, and the workpiece is cut by the rotating circular saw 204.

[0061] Loop cutting:

[0062] After a single cut is completed, a new workpiece is replaced.

[0063] Controlling the travel motor 207 to rotate in reverse will drive the cutter 202 to move in the opposite direction to the initial position, thus starting the next cut and achieving an automatic cyclic cutting effect.

[0064] Drive angle rotation:

[0065] Start the steering motor 103, which drives the worm gear 102 to rotate.

[0066] The worm gear 102 meshes with the transmission worm wheel 6, driving the transmission worm wheel 6 to rotate;

[0067] The transmission worm gear 6 drives the inner ring 7 and the hollow shaft 401 to rotate synchronously, thereby adjusting the angle of the positioning chuck 3 and the workpiece above it.

[0068] Angle limitation: The angle adjustment range does not exceed 90 degrees, which can effectively avoid the problem of equipment connection lines and oil pipes getting tangled, while meeting the cutting angle requirements of most workpieces.

[0069] After the angle is adjusted to the target position, the micro electric cylinder 8 is activated, and the micro electric cylinder 8 advances the positioning pin 801;

[0070] Precise fixing: Insert the positioning pin 801 into the positioning groove 404 of the positioning ring 403 to lock the position of the positioning ring 403, thereby maintaining the stability of the workpiece angle and facilitating subsequent processing operations.

[0071] Example 3: Error Problems and Positioning Optimization

[0072] Source of error: The meshing transmission between the worm gear 102 and the transmission worm wheel 6 is prone to positioning errors due to problems such as assembly accuracy deviation and component wear.

[0073] Advantages of the positioning method: The mechanical positioning method of "positioning groove 404 + positioning pin 801" has higher stability and better accuracy compared with the electronic positioning of proximity sensors. After the positioning pin 801 contacts the positioning groove 404, it can automatically align itself, and the position of the transmission worm gear 6 and the inner ring 7 can be adaptively adjusted to offset the transmission error.

[0074] The elastic structure function: A spring is provided between the propulsion tooth 701 of the inner ring 7 and the worm gear tooth 601 of the transmission worm gear 6. The spring provides elastic space for the adjustment of the relative position of the two, ensuring that the component can be self-adaptively fine-tuned when the positioning pin 801 is inserted into the positioning groove 404.

[0075] To avoid defects in fixed structures: If a fixed integrated worm gear structure is used, it will form a self-locking mechanism after meshing with the worm 102, which will force the angle of the positioning groove 404 to be fixed. It will be impossible to achieve accurate positioning of the workpiece angle through the adaptive adjustment of the positioning pin 801. Therefore, the flexible split structure is the key design to ensure positioning accuracy.

[0076] The specific usage and function of this embodiment: In this invention, when in use, the workpiece is placed above the positioning table 3, the clamping motor 306 is started to drive the clamping screw 305 to rotate, the clamping screw 305 drives the U-shaped clamp 304, and the two sets of U-shaped clamps 304 are brought together to fix the workpiece.

[0077] The lower oil pump 11 is responsible for supplying oil, and the upper oil pump 11 is responsible for returning oil. By opening the solenoid valve A502 outside the hydraulic telescopic cylinder 501 and the solenoid valve B503 above the inner liquid passage 9, oil can be injected into the hydraulic telescopic cylinder 501 using the oil pump 11, which opens the hydraulic telescopic cylinder 501 and fixes the workpiece. Through the control program, the hydraulic telescopic cylinder 501 and the U-shaped clamp 304 work together to fix the workpiece in the center.

[0078] Conversely, by closing the solenoid valve B503 above the inner fluid passage 9 and opening the solenoid valve B503 above the outer fluid passage 9, the hydraulic oil in the hydraulic control telescopic cylinder 501 can be drawn back to the oil tank 10 by the upper oil pump 11, which can control the retraction of the hydraulic control telescopic cylinder 501. By controlling the retraction of the hydraulic control telescopic cylinder 501 and the movement of the U-shaped clamp 304, the position of the workpiece can be adjusted, and the position can be moved while keeping the workpiece stable.

[0079] Start the cutting motor 203 to drive the circular saw 204 to rotate, start the travel motor 207 to drive the travel screw 206 to rotate, move the screw block 205 and the cutter 202 to cut, after the cutting is completed, change the workpiece, and then move the cutter 202 in the opposite direction to cut again, so as to achieve the effect of automatic cutting.

[0080] The steering motor 103 is started to drive the worm gear 102 to rotate, the worm gear 102 drives the transmission worm wheel 6 to rotate, and the transmission worm wheel 6 drives the inner ring 7 and the hollow shaft 401 to rotate. This allows the positioning table 3 and the workpiece to be adjusted. The angle adjustment does not exceed 90 degrees, which can prevent the wire and tube from getting tangled and meet most cutting requirements.

[0081] After adjusting the angle, start the miniature electric cylinder 8 to push the positioning pin 801, insert the positioning pin 801 into the positioning groove 404 to fix the position of the positioning ring 403, thus maintaining the workpiece angle and facilitating subsequent processing;

[0082] Because the transmission of the worm gear 102 and the transmission worm wheel 6 is prone to problems such as assembly and wear, there are certain errors. The positioning groove 404 is used for positioning, which is more stable and accurate than the positioning using a proximity sensor. After the positioning pin 801 contacts the positioning groove 404, it automatically aligns. The positions of the transmission worm wheel 6 and the inner ring 7 can automatically adapt and adjust. The spring between the push tooth 701 and the worm wheel tooth 601 provides an adaptive effect.

[0083] If a fixed integrated worm gear is used, the angle of the positioning groove 404 will be fixed after the worm gear and worm 102 are self-locked, and the positioning pin 801 cannot be used to accurately position the workpiece angle. Therefore, an adaptable transmission method is used for drive control.
