Description

Technical Field

[0001] The invention belongs to the technical field of thread processing, and in particular relates to an external thread grinder and an adjusting component thereof. Background Art

[0002] An external thread grinder refers to a thread processing machine tool that uses a formed grinding wheel as a grinding tool to process precision threads. It is mainly used for precision grinding of external threads of parts such as screws, worms, and lead screws (screws). With the continuous development and changes in various market demands, there are more and more styles of threaded parts such as ball screws and worms and internal threaded parts such as nuts and modules, and there are more and more models of external thread grinders used for processing.

[0003] For example, the Chinese patent with publication number CN112191955A discloses a debris collection device and a pipe threading lathe, wherein the debris generated during the pipe threading process falls into the receiving groove, driving the first lateral push plate and the second lateral push plate to push the scattered debris to a position close to the through hole, and the hydraulic cylinder drives the telescopic rod to extend, thereby driving the first clamping plate and the second clamping plate to move toward the through hole. During the movement, the first clamping plate and the second clamping plate respectively slide and abut against the first lateral push plate and the second lateral push plate, thereby pushing the debris between the first lateral push plate and the second lateral push plate into the through hole and falling into the placement tank, so that the debris generated by the processing can be cleaned into the placement tank.

[0004] In actual use, there are still the following problems:

[0005] In the current external thread grinder processing technology, external thread grinders are generally used for thread processing. This process requires the operator to place the workpiece to be processed in a chuck for fixing. However, this manual operation link has certain limitations, which are mainly reflected in the following aspects: First, it is difficult for the operator to place the workpiece in the chuck quickly and accurately, which affects the processing efficiency and accuracy; second, if the cutting fluid and lubricating oil used in the previous process of the workpiece are not thoroughly cleaned, the residual liquid and debris may adhere to the surface of the workpiece during storage or transportation. These impurities will cause wear on the tool during processing and even cause carbon deposition on the surface of the workpiece; in addition, the high temperature state of the workpiece after processing, as well as the picking and placing and hand-held operations of the workpiece, all bring considerable challenges to operational efficiency and safety.

[0019] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0020] 1. In the present invention, a rotating support wheel, a cleaning roller, a first gear, a second gear, an extrusion wheel, a movable plate, and a contact block are adopted. The rotating support wheel cleverly controls the rotation of the workpiece inside the support frame by using friction force, thereby ensuring the stable rotation of the workpiece. In this process, the rotation of the workpiece is transmitted through friction force, driving the cleaning roller, the rotating shaft and the first gear to rotate synchronously, and the cleaning roller effectively wipes and cleans the surface of the workpiece to remove residual cutting fluid, lubricating oil and debris. In addition, the rotation of the first gear accurately controls the movement of the second gear, the connecting shaft and the extrusion wheel. During the rotation process, the extrusion wheel applies pressure to the movable plate and the contact block to separate them from the fixed frame. When the extrusion wheel is separated from the movable plate, the second elastic component quickly intervenes to control the resetting of the movable plate and the contact block. At this time, the contact block acts on the fixed frame in a knocking manner, and the fixed frame then transmits this vibration to the surface of the workpiece, which is combined with the wiping action of the cleaning roller, thereby significantly improving the cleaning effect, so that the cleanliness of the workpiece surface is optimized.

[0021] 2. In the present invention, an air storage frame, an extrusion plate, an air outlet valve, an air inlet valve and an air outlet head are adopted. When the electric slider moves upward in the electric slide rail, the contact plate and the extrusion plate are synchronously pushed upward by the action of the cross bar. The movement of the extrusion plate effectively compresses the gas in the air storage frame, forcing the gas to be discharged through the air outlet valve, the intermediate pipe, the connecting plate and the air outlet head. The airflow blown upward by the air outlet head directly acts on the surface of the rotating workpiece, which greatly improves the cleaning effect of the workpiece itself and ensures the cleanliness of the workpiece surface. After the processing is completed, when the support frame removes the workpiece, the first elastic component plays a role to control the downward movement of the extrusion plate. At the same time, the suction effect of the air inlet valve accelerates the air flow near the workpiece. This design not only helps to quickly discharge the high temperature generated during the processing, but also accelerates the heat dissipation process of the workpiece, thereby improving the cooling efficiency of the workpiece and the stability after processing.

[0022] 3. In the present invention, a support frame, an electric slide rail and an electric slider are used. The electric slider slides in the vertical direction in the electric slide rail, so as to accurately control the vertical movement of the support frame. When the support frame moves upward, the workpiece to be processed can be accurately lifted to the center position of the rotary chuck assembly. The synergistic effect with the tailstock ensures that the workpiece is placed quickly and accurately, greatly improving the clamping efficiency. After the thread processing is completed, the support frame also plays a key role and can safely remove the workpiece in a high temperature state from the rotary chuck assembly. This design not only improves the accuracy and operating efficiency of workpiece placement, but also reduces potential risks of work-related injuries while ensuring operational safety.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] The use of a rotating motor 19 and a rotating support wheel 20 can utilize friction to control the rotation of the workpiece, so that the workpiece can rotate and contact the cleaning roller 213 to achieve wiping and cleaning of the workpiece. The electric slider 11 and the electric slide rail 12 cooperate to control the vertical movement of the support frame 9 and the workpiece, making it convenient to accurately move the workpiece to the position corresponding to the rotating chuck assembly 3, thereby facilitating the removal of the processed workpiece.

[0037] Specifically, Figure 1-3 As shown, the support frame 9 is configured to be V-shaped, a middle hole 16 is provided on the left side of the support frame 9 , the cross bar 13 is located at the lower side of the extrusion blowing device 14 , and the connecting plate 17 is located between the two rotating support wheels 20 .

[0038] Specifically, Figure 2-3 and Figure 7 As shown, the extrusion blowing device 14 includes an air storage frame 141, in which an extrusion plate 145 is slidably connected, the air storage frame 141 is connected to an air outlet valve 142, the air outlet valve 142 is connected to an intermediate tube 143, the other end of the intermediate tube 143 is connected to the connecting plate 17, and the side of the air storage frame 141 is connected to an air inlet valve 144, and the air inlet valve 144 and the air outlet valve 142 are both connected to the air storage cavity in the air storage frame 141 located on the upper side of the extrusion plate 145.

[0039] A vertical rod 147 is fixedly connected to the extrusion plate 145, and the vertical rod 147 passes through and is slidably connected to the bottom of the gas storage frame 141. A contact plate 148 is fixedly connected to the bottom end of the vertical rod 147. A first elastic component 146 is fixedly connected to the extrusion plate 145, and the first elastic component 146 is fixedly connected in the gas storage frame 141.

[0040] When the extrusion plate 145 moves upward, the gas in the gas storage frame 141 is squeezed and discharged through the outlet valve 142, the intermediate tube 143, the connecting plate 17 and the outlet head 18. The outlet head 18 blows gas upward to act on the surface of the rotating workpiece. When the extrusion plate 145 loses external extrusion, the first elastic component 146 controls the extrusion plate 145 to move downward, and the external gas is sucked into the gas storage frame 141 through the inlet valve 144.

[0041] Specifically, Figure 5-6 As shown, the rotating wiping mechanism 21 includes a fixed frame 211, which is fixedly connected to the elastic supporting mechanism 23. A rotating shaft 212 passes through both sides of the fixed frame 211 and is rotatably connected thereto. A cleaning roller 213 is fixedly connected to the outside of the rotating shaft 212. The rotating shaft 212 is disposed in the rotating vibration mechanism 22, and the cleaning roller 213 is disposed in the connecting hole 15.

[0042] The cleaning roller 213 can be used to wipe and clean the rotating workpiece surface, and the rotating shaft 212 rotates in the fixed frame 211, so that the cleaning roller 213 can rotate smoothly;

[0043] Specifically, Figure 3 , Figure 5 and Fig. 9 As shown, the elastic support mechanism 23 includes a movable frame 231, and the movable frame 231 is fixedly connected to one side close to the support frame 9 with two connecting rods 232, and the connecting rod 232 is fixedly connected to the outside of the support frame 9. A guide sleeve 233 is penetrated through the side of the movable frame 231, and a guide rod 234 is slidably connected in the guide sleeve 233. The guide rod 234 is fixedly connected to the outside of the fixed frame 211, and the other end of the guide rod 234 is fixedly connected to the outside of the fixed frame 211. A third elastic component 236 is provided on the outer sleeve of the guide rod 234, and the two ends of the third elastic component 236 are respectively fixedly connected to the guide sleeve 233 and the limiting plate 235.

[0044] The guide rod 234 and the guide sleeve 233 are used to allow the fixing frame 211 to slide along the guide sleeve 233. The elastic force of the third elastic component 236 acts on the outside of the guide rod 234 to keep the cleaning roller 213 in contact with the workpiece, and the elastic force can prevent the cleaning roller 213 from shaking randomly.

[0045] Specifically, Figure 3 , Figure 5 and Figure 8 As shown, the rotating vibration mechanism 22 includes a first gear 221 fixedly connected to the outside of the rotating shaft 212, a second gear 222 is meshed with the outside of the first gear 221, a connecting shaft 223 is fixedly connected to the axial position of the side of the second gear 222, the connecting shaft 223 is rotatably connected to the outside of the fixed frame 211, a pressing wheel 224 is fixedly connected to the side of the connecting shaft 223, a moving plate 225 is slidably connected to the side of the pressing wheel 224, and a contact block 226 is fixedly connected to the side of the moving plate 225 close to the fixed frame 211.

[0046] A linear bearing 227 is provided on the side of the movable plate 225, and a fixed rod 228 is slidably connected inside the linear bearing 227. The fixed rod 228 is fixedly connected to the outside of the fixed frame 211. A second elastic component 229 is provided on the outer sleeve of the fixed rod 228, and the other end of the second elastic component 229 is fixedly connected to the linear bearing 227.

[0047] The linear bearing 227 allows the fixed rod 228 to move linearly without rotating. The first gear 221 and the second gear 222 can use the rotation of the cleaning roller 213 to control the rotation of the extrusion wheel 224. The rotation process of the extrusion wheel 224 will intermittently squeeze the movable plate 225. The second elastic component 229 can control the movable plate 225 and the contact block 226 to quickly reset. The reset process of the contact block 226 will show a knocking effect on the fixed frame 211, and the knocking vibration acts on the fixed frame 211, the cleaning roller 213 and the workpiece surface.

[0048] An external thread grinder also includes a bed 1 and a support rail 2, the bed 1 is fixedly connected to the support rail 2, a tailstock 5 is slidably provided on the support rail 2, a first adjusting wheel group 6 is provided on the side of the tailstock 5, a rotating chuck assembly 3 is fixedly installed on the bed 1, and an electric slide rail 12 and an air storage frame 141 are both fixedly connected to the side of the support rail 2.

[0050] Working principle, when using:

[0051] First, the workpiece to be processed is placed on the support frame 9, and the elastic force of the third elastic component 236 controls the guide rod 234, the fixing frame 211 and the cleaning roller 213 to keep in contact with the workpiece, and then the electric hydraulic rod rotation motor 19 and the electric slide rail 12 are controlled to operate. The rotation motor 19 drives the rotation support wheel 20 to rotate while working. The rotation support wheel 20 uses friction to control the workpiece to rotate inside the support frame 9. During the rotation of the workpiece, the friction is used to drive the cleaning roller 213, the rotating shaft 212 and the first gear 221 to rotate, and the cleaning roller 213 wipes and cleans the surface of the workpiece;

[0052] The first gear 221 controls the second gear 222, the connecting shaft 223, and the extrusion wheel 224 to rotate. The extrusion wheel 224 will squeeze the movable plate 225 and the contact block 226 to separate from the fixed frame 211 during the rotation process. After the extrusion wheel 224 is separated from the movable plate 225, the second elastic component 229 controls the movable plate 225 and the contact block 226 to reset. The contact block 226 knocks on the fixed frame 211. The fixed frame 211 transmits the vibration to the workpiece surface through the cleaning roller 213, so that the cleaning roller 213 wipes the workpiece surface in coordination with the vibration, and the cleaning effect is better.

[0053] When the electric slider 11 moves upward in the electric slide rail 12, it squeezes the contact plate 148 and the squeezing plate 145 upward through the cross bar 13. When the squeezing plate 145 moves, the gas in the gas storage frame 141 is squeezed out through the gas outlet valve 142, the intermediate pipe 143, the connecting plate 17 and the gas outlet head 18. The gas outlet head 18 blows gas upward to act on the surface of the rotating workpiece, so that the cleaning effect of the workpiece itself is optimized. When the support frame 9 moves upward to move the workpiece to the position corresponding to the rotary chuck assembly 3, the tailstock 5 slides in the support rail 2 and pushes the workpiece to be inserted into the rotary chuck assembly 3. The rotary chuck assembly 3 clamps the workpiece in position, and the electric slider 11 moves downward to separate the support frame 9 from the workpiece, and then the workpiece can be threaded. After the threading is completed, the electric slider 11 moves upward to allow the support frame 9 to support the workpiece that has completed the threading. The electric slider 11 drives the support frame 9 and the workpiece to move downward to complete the removal operation of the workpiece.
