Description

Technical Field

[0001] This application relates to the field of sleeve end face cutting equipment technology, and in particular to a lathe system with sleeve height detection. Background Technology

[0002] A face cutting device is a device or tool used to cut the end face of a material. It is commonly used in the metalworking industry, particularly in steel manufacturing and processing. Face cutting devices can achieve the face cutting of materials through cutting, grinding, or other methods.

[0003] The design and function of end-face cutting devices can vary depending on different application requirements. Some common end-face cutting devices include cutting machines, cutting saws, and cutting blades. These devices are typically equipped with appropriate cutting tools or blades to ensure the accuracy and efficiency of the cutting process. In steel manufacturing and processing, end-face cutting devices are commonly used to cut the end faces of steel. They can be used for length cutting, cutting welded joints, preparing materials for subsequent processing, etc. By using end-face cutting devices, flat and precise cut end faces can be obtained to meet various engineering and manufacturing requirements.

[0004] Regarding the aforementioned technologies, when cutting the end face of the sleeve, the sleeve needs to be fitted onto one end of the fixed post, and the fixed post supports the sleeve. Metal shavings are easily attached to the outside of the fixed post. When fitting the sleeve, the sleeve is pushed outward by a certain distance, resulting in a large cutting error when cutting the sleeve. Summary of the Invention

[0005] To reduce cutting errors, this application provides a lathe system with sleeve height detection.

[0006] This application provides a lathe system with sleeve height detection, which adopts the following technical solution:

[0007] A lathe system with sleeve height detection includes a base, a support rod for supporting the sleeve is provided at the upper end of the base, a cutting mechanism for cutting the sleeve is provided above the base, air nozzles for blowing air to the connection between the support rod and the sleeve are provided on both sides of the support rod, the air nozzles are directly opposite one end of the support rod, the air nozzles are connected to an air supply pipe, the air supply pipe is connected to the base, and the support rod is provided with an opening and closing element for controlling the opening or closing of the air supply pipe.

[0008] By adopting the above technical solution, the sleeve is placed before one end of the support rod. The opening and closing device is activated, which opens the air supply pipe. Then, the air nozzle sprays gas to the support rod, blowing off the metal debris on the support rod. The sleeve is then placed on one end of the support rod, and the cutting mechanism cuts the end face of the sleeve. This helps to reduce the metal debris adhering to the support rod and affecting the cutting of the sleeve end face, thereby reducing cutting errors.

[0009] Optionally, the opening and closing component includes an abutment ring, a transverse rack, a transverse gear, an opening and closing valve for opening or closing the gas pipeline, and a reset assembly for driving the abutment ring to reset. The opening and closing valve is coaxially connected to the transverse gear, the transverse gear meshes with the transverse rack, the transverse rack is fixedly connected to one side of the abutment ring, the transverse rack is perpendicular to the abutment ring, the abutment ring is coaxially arranged with the support rod, and the transverse rack is slidably connected to the support rod. In the initial state, there is a gap between the abutment ring and the support rod. When the abutment ring abuts against the support rod, the opening and closing valve opens the gas pipeline.

[0010] By adopting the above technical solution, when installing the sleeve, one end of the sleeve abuts against one side of the contact ring, which helps to improve the accuracy of installation. The sleeve moves laterally towards the support rod, which drives the contact ring to move laterally. The contact ring drives the lateral rack to move laterally, which drives the lateral gear to rotate. The rotation of the lateral gear drives the opening and closing valve to rotate. When the contact ring just abuts against the support rod, the opening and closing valve opens the gas supply pipe, and the gas supply pipe delivers gas to the gas nozzle, so that the support rod is cleaned during the installation of the sleeve.

[0011] Optionally, the reset assembly includes a fixed ring and a reset spring. The fixed ring is sleeved on the outside of the support rod and is rotatably connected to the support rod through a bearing. The fixed ring and the abutment ring are arranged parallel to each other and on the same horizontal plane. One end of the reset spring is fixedly connected to the side of the fixed ring near the abutment ring, and the other end of the reset spring is fixedly connected to the transverse rack. The reset spring and the transverse rack are arranged parallel to each other.

[0012] By adopting the above technical solution, when the contact ring moves laterally toward the support rod, it drives the transverse rack to squeeze the return spring. The fixed ring supports the return spring. After the sleeve is cut, the sleeve separates from the support rod, and the return spring rebounds, driving the contact ring to return to its original position, thus facilitating the processing of different sleeves.

[0013] Optionally, the upper end of the base is fixedly connected to a cover, the support rod is rotatably connected to the cover, the cutting mechanism is fixedly connected to the upper end of the cover, and one end of the cover is fixedly connected to a drive motor for driving the support rod to rotate.

[0014] By adopting the above technical solution, the machine cover supports the support rod and the cutting mechanism. When the sleeve needs to be cut, the drive motor is driven, which drives the support rod to rotate, thereby facilitating circumferential cutting of the sleeve end face. The machine cover also helps to reduce metal debris from splashing to other places.

[0015] Optionally, the cutting mechanism includes a cutting tool for cutting the sleeve, a lifting cylinder for driving the cutting tool to rise and fall, and a connecting block for connecting the lifting cylinder and the cutting tool. The cylinder body of the lifting cylinder is fixedly connected to the upper end of the machine cover, the lifting cylinder is vertically arranged, the connecting block is detachably connected to the piston rod of the lifting cylinder, and the lower end of the connecting block is connected to the cutting tool.

[0016] By adopting the above technical solution, when the sleeve needs to be cut, the lifting cylinder is activated. The piston rod of the lifting cylinder drives the connecting block to descend, and the connecting block drives the cutting tool to descend to the end face of the sleeve, thus making the process of cutting the end face of the sleeve more convenient.

[0017] Optionally, one side of the base is provided with a robotic arm for installing or removing sleeves, and another side of the base is provided with a placement plate for holding sleeves, with several grooves for engaging sleeves on the upper surface of the placement plate.

[0018] By adopting the above technical solution, the robotic arm is driven to install the sleeve onto the support rod, and the processed sleeve is removed and placed in the groove of the placement plate, which helps to reduce the workload of the workers.

[0019] Optionally, both ends of the placement plate are fixedly connected to connecting frames, and the connecting frames are embedded with lifting screws. A lifting plate is threaded between the two lifting screws. The lifting plate is slidably connected to the connecting frames and is parallel to the placement plate. The lifting plate has several through holes that extend along the height direction of the lifting plate. The through holes are opposite to the grooves. Several sliding blocks are slidably connected to the lifting plate. The sliding blocks are slidably connected to the through holes of the lifting plate. Two limiting plates for limiting the separation of the sliding blocks from the lifting plate are fixedly connected to the outside of the sliding blocks. The limiting plates are slidably connected to the through holes of the lifting plate. A support plate is fixedly connected to the upper end of the connecting frame. A compression cylinder is fixedly connected to the upper end face of the support plate. A compression plate is fixedly connected to the end of the piston rod of the compression cylinder that passes through the support plate. The compression plate is horizontally arranged. An elastic layer is fixedly connected to the lower end face of the compression plate. The lower end face of the elastic layer is movably connected to the end of the sliding block that protrudes from the lifting plate.

[0020] By adopting the above technical solution, after the sleeve is placed on the placement plate, the lifting screw is rotated, the lifting plate descends, and the lifting plate drives the sliding block to descend until it contacts the sleeve. If the sleeve with an excessively large end face cut does not contact the sliding block, the extrusion cylinder is activated. The piston rod of the extrusion cylinder extends, driving the extrusion plate to descend. The extrusion plate drives the elastic layer to descend, and the elastic layer extrudes the sliding block. The sleeve with an excessively large end face cut contacts the sliding block, and then the sliding block descends. This makes it more convenient for workers to discover defective sleeves.

[0021] Optionally, the lifting plate is fixedly connected with several lifting racks, which are vertically arranged at the through holes of the lifting plate. A drive gear is rotatably connected inside the sliding block. The drive gear meshes with the lifting racks. A rotating rod is coaxially connected to the drive gear. The rotating rod is connected to a driven gear through a bevel gear pair. The driven gear is coaxially connected to the sliding block. Both sides of the driven gear are meshed with linkage racks. The linkage racks are slidably connected to the sliding block. A clamping plate is fixedly connected to one end of the linkage rack that extends out of the sliding block. The clamping plate is vertically arranged. When the sliding block descends, the two clamping plates move closer to each other.

[0022] By adopting the above technical solution, during the descent of the sliding block, the lifting rack drives the driving gear to rotate, the driving gear drives the rotating rod to rotate, the rotating rod drives the driven gear to rotate through the bevel gear pair, and the driven gear drives the two clamping plates to move closer to each other through the linkage rack. The two clamping plates clamp the sleeve, and when the lifting plate rises, the unqualified sleeve is picked out, which facilitates the collection of qualified sleeves.

[0023] In summary, this application includes at least one of the following beneficial technical effects of a lathe system with sleeve height detection:

[0024] By setting up an air nozzle, air supply pipe, and opening / closing device, the sleeve is placed before one end of the support rod. Activating the opening / closing device opens the air supply pipe, allowing the air nozzle to spray gas onto the support rod, blowing off metal debris. Then, the sleeve is placed on one end of the support rod, and the cutting mechanism cuts the end face of the sleeve. This helps reduce the amount of metal debris adhering to the support rod and affecting the cutting of the sleeve end face, thereby reducing cutting errors. Attached Figure Description

[0032] The present application will be further described in detail below with reference to all the accompanying drawings.

[0033] This application discloses a lathe system with sleeve height detection.

[0034] Reference Figure 1 A lathe system with sleeve height detection includes a support mechanism 1, a cutting mechanism 2, a cleaning mechanism 3, a conveying mechanism 4, and a detection mechanism 5. The support mechanism 1 supports the cutting mechanism 2 and the cleaning mechanism 3. The conveying mechanism 4 and the detection mechanism 5 are located on one side of the support mechanism 1. The cleaning mechanism 3 cleans the connection between the sleeve and the support mechanism 1. The support mechanism 1 supports the sleeve. The cutting mechanism 2 cuts the end face of the sleeve. The conveying mechanism 4 conveys the sleeve. The detection mechanism 5 selects out unqualified sleeves, thereby reducing the need for workers to manually select unqualified sleeves one by one and reducing the workload of workers.

[0035] Reference Figure 1 and Figure 2 The support mechanism 1 includes a base 11, a cover 12, a support rod 13, a drive motor 14, a clamping cylinder 15, and a clamping block 16. The base 11 is rectangular. The cover 12 is fixedly connected to the upper surface of the base 11. The support rod 13 is fixedly connected to one end of the cover 12 and is horizontally arranged. The drive motor 14 is fixedly connected to one end of the cover 12 and the output shaft of the drive motor 14 is coaxially connected to the support rod 13. The clamping cylinder 15 is fixedly connected to one end of the cover 12 and is horizontally arranged and at the same level as the support rod 13. The clamping block 16 is fixedly connected to the piston rod of the clamping cylinder 15 and faces the support rod 13.

[0036] Reference Figure 1 and Figure 2 The base 11 supports the machine cover 12, which in turn supports the support rod 13, drive motor 14, and clamping cylinder 15. When the sleeve needs to be cut, the sleeve is placed on one end of the support rod 13, which supports the sleeve. The clamping cylinder 15 is activated, and its piston rod extends, causing the clamping block 16 to move laterally. The clamping block 16 presses the sleeve, which helps to reduce the possibility of the sleeve falling off. When the sleeve is ground and cut, the machine cover 12 helps to reduce the possibility of metal chips flying out and injuring people. At the same time, the drive motor 14 is activated, which drives the support rod 13 to rotate, which facilitates circumferential cutting of the sleeve end face.

[0037] Reference Figure 1 and Figure 2 The cutting mechanism 2 includes a lifting cylinder 21, a connecting block 22, and a cutting tool 23. The cylinder body of the lifting cylinder 21 is fixedly connected to the upper end of the machine cover 12. The lifting cylinder 21 is vertically arranged. The connecting block 22 is fixedly connected to the piston rod of the lifting cylinder 21. The cutting tool 23 is detachably connected to the lower end of the connecting block 22 by bolts. When the sleeve needs to be cut, the lifting cylinder 21 is activated. The piston rod of the lifting cylinder 21 drives the connecting block 22 to descend, and the connecting block 22 drives the cutting tool 23 to descend to the end face of the sleeve, thus making the process of cutting the end face of the sleeve more convenient.

[0038] Reference Figure 1 and Figure 3 The cleaning mechanism 3 includes two air supply pipes 31, two air nozzles 32, and an opening and closing component 33. The opening and closing component 33 includes an abutment ring 331, two transverse racks 332, two transverse gears 333, two opening and closing valves 334, and a reset assembly 34. The reset assembly 34 includes a fixed ring 341 and two reset springs 342. The fixed ring 341 is coaxially connected to the support rod 13 through a bearing. The reset springs 342 are fixedly connected to one side of the fixed ring 341. The two reset springs 342 are symmetrically arranged and are parallel to the support rod 13. The end of the reset spring 342 away from the fixed ring 341 is fixedly connected to the transverse rack 332. The transverse rack 332 is horizontally arranged. The abutment ring 331 is fixedly connected between the two transverse racks 332 and is coaxially connected to the support rod 13. The transverse rack 332 meshes with the transverse gear 333, the transverse gear 333 is coaxially connected with the on / off valve 334, the on / off valve 334 is set on the air supply pipe 31, the air supply pipe 31 is fixedly connected to the base 11, the air nozzle 32 is fixedly connected to the end of the air supply pipe 31 away from the base 11, the air supply pipe 31 and the air nozzle 32 are connected, and the air nozzle 32 is directly facing the end of the support rod 13 near the contact ring 331.

[0039] Reference Figure 1 and Figure 3When installing the sleeve, one end of the sleeve abuts against one side of the contact ring 331, which helps improve the accuracy of installation. The sleeve moves laterally towards the support rod 13, causing the contact ring 331 to move laterally. The contact ring 331 drives the transverse rack 332 to move laterally, and the transverse rack 332 drives the transverse gear 333 to rotate. The transverse gear 333 drives the on / off valve 334 to rotate. When the contact ring 331 just abuts against the support rod 13, the on / off valve 334 opens the gas supply pipe 31, and the gas supply pipe 31 delivers gas to the gas nozzle 32. Then the gas nozzle 32 sprays the gas onto the support rod 13, blowing off the metal debris on the support rod 13. Then the sleeve is fitted onto one end of the support rod 13, which helps reduce the metal debris adhering to the support rod 13 and affecting the cutting of the sleeve end face, thus helping to reduce cutting errors.

[0040] Reference Figure 1 and Figure 3 When the abutment ring 331 moves laterally toward the support rod 13, it drives the transverse rack 332 to squeeze the return spring 342. The fixed ring 341 supports the return spring 342. After the sleeve is cut, the sleeve separates from the support rod 13, and the return spring 342 rebounds, driving the abutment ring 331 to return to its original position, thus facilitating the processing of different sleeves.

[0041] Reference Figure 1 and Figure 4 The conveying mechanism 4 includes a robotic arm 41 and a placement plate 42, which are located on one side of the base 11. The upper end of the placement plate 42 has several grooves for engaging the sleeve. The robotic arm 41 is driven to install the sleeve onto the support rod 13. At the same time, the robotic arm 41 can remove the processed sleeve and place it in the grooves of the placement plate 42. The grooves prevent the sleeve from shaking, thereby reducing the workload of the workers.

[0042] Reference Figure 4 and Figure 5The testing mechanism 5 includes two connecting frames 51, two lifting screws 52, two lifting motors 53, a lifting plate 54, several sliding blocks 55, a support plate 56, a compression cylinder 57, a compression plate 58, and several clamping components 59. The connecting frames 51 are fixedly connected to both ends of the placement plate 42 and are vertically arranged. The lifting screws 52 are rotatably connected to the connecting frames 51 and are vertically arranged. The two ends of the lifting plate 54 are threadedly engaged with the two lifting screws 52 respectively, and the lifting plate 54 is slidably connected to the connecting frames 51. The lifting motors 53 are fixedly connected to the upper end of the connecting frames 51, and the output shaft of the lifting motors 53 is coaxially connected to the lifting screws 52. The lifting plate 54 has several through holes. Extending along the height direction of the lifting plate 54, a sliding block 55 is slidably connected to the through hole of the lifting plate 54. Two limiting plates 551 are fixedly connected to the outside of the sliding block 55. The limiting plates 551 are slidably connected to the through hole of the lifting plate 54. A support plate 56 is fixedly connected between two connecting frames 51. The support plate 56 is set at the upper end of the connecting frame 51 and is horizontally set. A compression cylinder 57 is fixedly connected to the upper end face of the support plate 56 and is vertically set. The piston rod of the compression cylinder 57 passes through one end of the support plate 56 and is fixedly connected to the compression plate 58. The compression plate 58 is horizontally set. An elastic layer 581 is fixedly connected to the lower end face of the compression plate 58 and is evenly distributed.

[0043] Reference Figure 4 and Figure 5 When the sleeve is placed on the placement plate 42, the lifting motor 53 is started. The output shaft of the lifting motor 53 rotates, which drives the lifting screw 52 to rotate. The lifting plate 54 descends, and the lifting plate 54 drives the sliding block 55 to descend until it contacts the sleeve. The sleeve with an oversized end face does not contact the sliding block 55. The extrusion cylinder 57 is started. The piston rod of the extrusion cylinder 57 extends, which drives the extrusion plate 58 to descend. The extrusion plate 58 drives the elastic layer 581 to descend. The elastic layer 581 extrudes the sliding block 55. The sleeve with an oversized end face contacts the sliding block 55, and then the sliding block 55 descends. This makes it easier for workers to find defective sleeves.

[0044] Reference Figure 5 and Figure 6The clamping assembly 59 includes a lifting rack 591, a driving gear 592, a rotating rod 593, a driven gear 594, two linkage racks 595, and two clamping plates 596. The lifting rack 591 is fixedly connected to the through hole of the lifting plate 54 and is vertically arranged. The driving gear 592 is rotatably connected to the sliding block 55 and is disposed inside the sliding block 55. The driving gear 592 meshes with the lifting rack 591. 2. It is coaxially connected to the rotating rod 593. The rotating rod 593 is connected to the driven gear 594 through a bevel gear pair. The driven gear 594 is horizontally set. Two linkage racks 595 are respectively meshed on both sides of the driven gear 594. The linkage racks 595 are slidably connected to the sliding block 55. One end of the linkage rack 595 that passes through the sliding block 55 is fixedly connected to the clamping plate 596. The clamping plate 596 is vertically set. The two clamping plates 596 are symmetrically set along the axis of the sliding block 55.

[0045] Reference Figure 5 and Figure 6 During the descent of the sliding block 55, the lifting rack 591 drives the drive gear 592 to rotate, the drive gear 592 drives the rotating rod 593 to rotate, the rotating rod 593 drives the driven gear 594 to rotate through the bevel gear pair, and the driven gear 594 drives the two clamping plates 596 to move closer to each other through the linkage rack 595. The two clamping plates 596 clamp the sleeve, and when the lifting plate 54 rises, the unqualified sleeve is picked out, which facilitates the collection of qualified sleeves.

[0046] The implementation principle of a lathe system with sleeve height detection according to an embodiment of this application is as follows: When installing the sleeve, one end of the sleeve abuts against one side of the abutment ring 331. The sleeve moves laterally towards the support rod 13, causing the abutment ring 331 to move laterally. The abutment ring 331 drives the transverse rack 332 to move laterally. The transverse rack 332 drives the transverse gear 333 to rotate. The transverse gear 333 drives the on / off valve 334 to rotate. When the abutment ring 331 just abuts against the support rod 13, the on / off valve 334 opens the air supply pipe 31. The air supply pipe 31 delivers gas to the air nozzle 32, and then the air nozzle 32 sprays the gas to the support rod 13, blowing off the metal debris at the support rod 13.

[0047] After the sleeve is fitted onto one end of the support rod 13, the lifting cylinder 21 is activated. The piston rod of the lifting cylinder 21 drives the connecting block 22 to descend, and the connecting block 22 drives the cutting tool 23 to descend to the end face of the sleeve. The cutting tool 23 cuts the end face of the sleeve.

[0048] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
