Description

Technical Field

[0001] The present invention relates to the technical field of screw production and processing, and in particular to a high-precision screw intelligent processing device and a processing method. Background Art

[0002] As an important mechanical part, lead screw is widely used in the manufacturing industry. Traditional lead screw processing mainly relies on machine tools. However, these traditional equipment have many limitations in practical applications, which seriously affects production efficiency and product quality.

[0003] First, traditional machine tools rely heavily on manual operation. During the screw processing, manual operations are required, such as loading and unloading, adjusting the workpiece position, changing tools, and handling waste. This not only increases labor costs, but also leads to low production efficiency. The instability and inaccuracy of manual operation also make it difficult to ensure processing accuracy, and product quality varies. Especially in the processing of high-precision screws, this manual-dependent method often cannot meet strict quality requirements.

[0004] Secondly, the waste and coolant generated by traditional machine tools during the processing process are often not effectively collected and treated. The scattering of waste and coolant not only deteriorates the working environment and poses a threat to the health of operators, but may also damage the equipment and shorten its service life. At the same time, the accumulation of waste and the retention of coolant may also affect the processing accuracy and product quality. Therefore, an effective waste treatment and cooling system is essential to improve production efficiency and product quality.

[0005] In order to overcome the limitations of traditional machine tools, some screw processing equipment with a high degree of automation has been developed. However, these devices still have certain limitations.

[0006] First of all, the structure of these automation equipment is often complex, resulting in high costs. The high equipment cost not only increases the investment pressure of enterprises, but also may limit the widespread application of equipment. Especially in some small and medium-sized enterprises, due to funding constraints, they are often unable to introduce these advanced automation equipment.

[0007] Secondly, although these automated equipment have improved the degree of automation to a certain extent, they still require a lot of manual intervention. In particular, manual operations are still required in loading and unloading, workpiece positioning, and tool replacement. This not only increases labor costs, but may also introduce human errors, affecting processing accuracy and product quality. Therefore, truly fully automatic screw processing equipment is still an issue that needs to be solved urgently.

[0008] In addition, these automated equipment generally use a horizontal processing method for processing lead screws. In this method, the transmission device is affected by gravity, resulting in greater vibration and worse stability. When processing the lead screw, the vibration of the lead screw is relatively large, especially the middle part is prone to bending, resulting in low precision in the production of the lead screw. In the horizontal processing method, a follower plate is often used to position and support the lead screw, which can reduce the bending caused by lead screw processing under certain circumstances. However, since the follower plate is fixed on the tool seat and shares a set of moving pairs with the tool, the follower plate will jump with the tool, resulting in limited ability to increase processing accuracy.

[0021] A processing method of a high-precision lead screw intelligent processing device comprises the following steps

[0022] Device preparation and initialization:

[0023] Ensure that the chuck mechanism, top mechanism, cutting tool mechanism, automatic loading mechanism, automatic unloading mechanism and adjustment mechanism of the high-precision screw intelligent processing device are in good working condition, initialize the control system, and ensure that the electrical components are correctly connected and respond to instructions;

[0024] At the starting position, the tool seat of the tool mechanism is located at the upper end of the high-precision linear guide, the adjustment hydraulic cylinder and the top hydraulic cylinder are in a retracted state, and the chuck mechanism is in a fully open state;

[0025] Automatic loading:

[0026] Place the screw material to be processed into the sliding box of the automatic feeding mechanism, and ensure that the screw material to be processed is inside the feeding port;

[0027] The loading hydraulic cylinder drives the sliding box forward, so that the screw material to be processed follows the sliding box into the processing area;

[0028] The control module controls all the adjustment hydraulic cylinders to drive the positioning block to move inward and fully insert it into the slot, so that the lead screw material to be processed is located in the arc-shaped positioning groove of the positioning block;

[0029] The feeding hydraulic cylinder drives the sliding box to retreat, and the screw material to be processed is completely transferred to the arc-shaped positioning groove of the positioning block, and the lower end of the screw material to be processed falls on the upper side of the automatic chuck;

[0030] Positioning and clamping:

[0031] The positioning block of the adjustment mechanism continues to slide inward under the drive of the adjustment hydraulic cylinder, thereby driving the screw material to be processed to slide inward, and the lower end of the screw material to be processed finally falls into the interior of the automatic chuck, and the bottom of the lower end of the screw material to be processed falls on the material withdrawal block;

[0032] The automatic chuck automatically centers and clamps the lower end of the screw material to be processed, and supports the upper end side of the screw material to be processed through the top mechanism;

[0033] Cutting process:

[0034] The automatic chuck of the chuck mechanism is driven by the transmission motor to rotate through the transmission and the rotating gear, thereby driving the rotation of the lead screw material to be processed, and the automatic tool changer is fed through the tool feed seat, and the tool of the automatic tool changer cuts the backing groove on the outer side of the upper end of the lead screw material to be processed;

[0035] Adjust the feed rate of the automatic tool changer disc, operate the tool moving motor, and cut off the outer skin of the lead screw material to be processed;

[0036] After the outer skin of the screw material to be processed is cut off, the tool moving motor is paused, and the tool stays at the position of the tool withdrawal groove. Then, according to the parameters of the screw to be processed, the rotation speed of the transmission motor of the chuck mechanism and the operating parameters of the tool moving motor are adjusted. The automatic tool changer automatically changes the tool according to the processing requirements, and the control module controls the adjustment of the hydraulic cylinder to make the inner side of the arc-shaped positioning groove close to the outer side of the screw material with the outer skin cut off, and the control module controls the laser emission module to emit laser, and the laser can just pass through each laser hole and be received by the laser receiving module. Then, the feed amount of the tool is adjusted, and the tool moving motor is operated to cut the spiral groove of the screw.

[0037] Automatic Adjustment:

[0038] During the cutting process, if the sensor module detects that there is a laser on a certain photosensitive film, it means that the lead screw in the processing is bent at the processing position due to the extrusion of the tool. At this time, the control module controls the adjustment hydraulic cylinder corresponding to the photosensitive film with the laser to extend to compensate for the bending amount of the lead screw. The extension length of the adjustment hydraulic cylinder is the deviation amount of the laser from the laser hole. The deviation amount is detected by the control module through the sensor module.

[0039] Waste handling and cooling:

[0040] The waste generated during the cutting process is sucked in through the suction hood and falls into the waste collection box. The exhaust fan connected to the exhaust pipe works, and the coolant nozzle sprays coolant to cool and clean the cutting area.

[0041] Automatic unloading:

[0042] After the processing is completed, the tool moving motor pauses, the tool stays at the position of the tool withdrawal groove to complete the tool withdrawal, the chuck mechanism releases the material, the push hydraulic cylinder drives the material withdrawal block to push the lower end of the screw out of the inner side of the automatic chuck, and then the hydraulic rod of the adjustment hydraulic cylinder at the bottom is extended, and the hydraulic rod of the adjustment hydraulic cylinder at the bottom is shortened, so that the lower end of the screw will be pushed into the unloading chute, the screw is in an inclined state, and finally slides onto the conveyor belt and passes through the conveyor belt delivery device;

[0043] Cycle processing:

[0044] Repeat the above steps to achieve continuous and high-precision screw processing.

[0045] According to a preferred technical solution, in the cutting process step, when cutting the spiral groove of the lead screw, the tool can be fed and cut multiple times.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] High degree of automation: This high-precision lead screw intelligent processing device integrates functions such as automatic loading, positioning and clamping, cutting processing, waste disposal and automatic unloading. It can realize the full process automated production from raw materials to finished products, significantly reduce labor costs and improve production efficiency.

[0048] High processing precision: The position of the lead screw is precisely controlled by adjusting the mechanism, and the high-precision cutting tool mechanism is used to ensure the accuracy of the processing process and produce high-quality lead screw products. Vertical processing of the lead screw can reduce the impact of gravity on equipment transmission and processing of the lead screw, which is beneficial to improving processing accuracy, enhancing production efficiency, and reducing the impact of thermal deformation.

[0049] Intelligent control: The intelligent control system composed of laser transmitting module, laser receiving module, photosensitive film, sensor module, etc. monitors the processing status in real time and adjusts automatically, which not only ensures the processing accuracy but also improves the adaptability of the processing process.

[0050] Waste and cooling treatment: The used coolant and impurities generated by cutting are sucked through the suction hood, which not only ensures the cleanliness of the working environment, but also cools the cutting area through the coolant nozzle, extending the service life of the tool.

[0051] Continuous production capability: The device supports continuous processing and realizes rapid material replacement through automatic loading and unloading mechanism, which enables the device to operate uninterruptedly and further improves production efficiency.

[0052] In short, this high-precision lead screw intelligent processing device provides a high-efficiency, high-precision, and low-cost solution for the production of lead screws through its highly automated and intelligent design, which is particularly suitable for large-scale production environments.

[0078] Automatic loading:

[0079] Place the lead screw material 100 to be processed into the sliding box 72 of the automatic feeding mechanism 7, and ensure that the lead screw material 100 to be processed is inside the feeding port 78;

[0080] The feeding hydraulic cylinder 73 drives the sliding box 72 forward, and the tool of the cutting tool mechanism 6 and the suction cover 67 correspond to the position of the avoidance groove 79, so as to prevent the sliding box 72 from touching the parts of the cutting tool mechanism 6 during the forward movement. The sliding box 72 moves forward so that the lead screw material 100 to be processed follows the sliding box 72 into the processing area;

[0081] The control module controls all the adjustment hydraulic cylinders 92 to drive the positioning block 93 to move inward and fully insert it into the slot 75, so that the lead screw material 100 to be processed is located in the arc-shaped positioning slot 94 of the positioning block 93;

[0082] The feeding hydraulic cylinder 73 drives the sliding box 72 to retreat, the bending plate 76 flips over, the screw material 100 to be processed is completely transferred to the arc-shaped positioning groove 94 of the positioning block 93, the return spring 77 and the bending plate 76 return to their original positions, and the lower end of the screw material 100 to be processed falls on the upper side of the automatic chuck 41;

[0083] Positioning and clamping:

[0084] The positioning block 93 of the adjustment mechanism 9 continues to slide inward under the drive of the adjustment hydraulic cylinder 92, thereby driving the screw material 100 to be processed to slide inward, and the lower end of the screw material 100 to be processed finally falls into the interior of the automatic chuck 41, and the bottom of the lower end of the screw material 100 to be processed falls on the material stripping block 84;

[0085] The automatic chuck 41 automatically centers and clamps the lower end of the screw material 100 to be processed, and supports the upper end side of the screw material 100 to be processed through the top mechanism 5;

[0086] Cutting process:

[0089] After the outer skin of the screw material 100 to be processed is cut off, the tool moving motor 66 is paused, and the tool stays at the position of the tool withdrawal groove.

[0090] Automatic Adjustment:

[0091] like Figure 1 As shown, during the cutting process, if the sensor module 98 detects that there is a laser on a certain photosensitive film 97, it means that the lead screw being processed is bent at the processing position due to the extrusion of the tool. At this time, the control module controls the adjustment hydraulic cylinder 92 corresponding to the photosensitive film 97 with the laser to extend to compensate for the bending amount of the lead screw. The length of the extension of the adjustment hydraulic cylinder 92 is the deviation amount of the laser from the laser hole. The deviation amount is detected by the control module through the sensor module 98;

[0095] like Figure 8 As shown, after the processing is completed, the tool moving motor 66 is paused, the tool stays at the position of the tool withdrawal groove to complete the tool withdrawal, the chuck mechanism 4 releases the material, the push hydraulic cylinder 83 drives the material withdrawal block 84 to push the lower end of the screw out of the inner side of the automatic chuck 41, and then the hydraulic rod of the lower adjustment hydraulic cylinder 92 is extended, and the hydraulic rod of the lower adjustment hydraulic cylinder 92 is shortened, so that the lower end of the screw will be pushed into the unloading groove 81, the screw is in an inclined state, and finally slides onto the conveyor belt 82 and is sent out of the device through the conveyor belt 82;

[0096] Cycle processing:

[0097] Repeat the above steps to achieve continuous and high-precision screw processing.

[0098] In the cutting process step, when cutting the spiral groove of the lead screw, the tool can be fed multiple times and cut multiple times.
