An on-line calibration device for a spinning machine

Abstract

This utility model discloses an online calibration device for a spinning machine, belonging to the technical field of spinning equipment. It includes a frame, an electric push rod fixedly connected to the inner wall of the frame, a rotating seat fixedly connected to the upper end of the frame, and an abutment seat fixedly connected to the telescopic end of the electric push rod. The abutment seat is slidably connected to the upper end of the frame. An adjustment mechanism is also installed at the upper end of the frame. The device performs a centering calibration operation on the sheet metal being spun. By slowly rotating the sheet metal, the rotating handle gradually rotates, causing the threaded column to rotate within the threaded sleeve, allowing the sliding seat to move along a fixed rail. Two abutment seats sequentially contact the sheet metal, which can be clamped and positioned using a tool clamp. The rotating handle is then moved to the center of the calibration assembly for positioning, reducing the large offset between the center of the sheet metal and the rotation center. This helps to distribute the centrifugal force more evenly during sheet metal rotation, ensuring a higher yield rate for the finished product.

Description

Technical Field

[0001] This utility model relates to the field of spinning equipment technology, and specifically to an online calibration device for a spinning machine. Background Technology

[0002] Spinning is a process that uses a spinning wheel and a mandrel to rotate and extrude a blank into shape. Spinning forming technology is a pressure processing technology that uses the near point contact between the spinning wheel and the workpiece and the unit high pressure to cause local plastic deformation of the processed material. This forming technology has the advantages of high material utilization and significantly improved processing performance. It is suitable for processing high-strength and difficult-to-deform materials and integral processing of seamless rotating hollow parts.

[0003] A search of existing technology revealed a "large horizontal spinning machine suitable for long-distance spinning," with publication number "CN209189580U." This device uses a slide table mechanism to mount the spinning wheel and is driven by a slide rail and screw mechanism, enabling long-distance spinning of long workpieces. However, when spinning sheet metal, the sheet metal may deviate significantly from the rotation center during placement, resulting in abnormal centrifugal force distribution during spinning and affecting the yield of finished products.

[0004] Based on this, the present invention designs an online calibration device for a spinning machine to solve the above problems. Utility Model Content

[0005] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an online calibration device for spinning machines.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An online calibration device for a spinning machine includes a frame, an electric push rod fixedly connected to the inner wall of the frame, a rotating seat fixedly connected to the upper end of the frame, an abutment seat fixedly connected to the telescopic end of the electric push rod, the abutment seat being slidably connected to the upper end of the frame, and an adjustment mechanism installed at the upper end of the frame. The adjustment mechanism includes a guide rail installed at the upper end of the frame, a support plate slidably connected to the upper end of the guide rail, an adjustment component at the upper end of the support plate, two calibration components inside the adjustment component, the calibration components being installed at the upper end of the support plate, and a rectangular hole at the upper end of the support plate.

[0008] Furthermore, the adjustment assembly includes multiple fixed rails fixedly connected to the upper end of the support plate, a translation plate slidably connected to the upper end of the fixed rails, multiple abutment brackets fixedly connected to the upper end of the translation plate, and two sliding seats fixedly connected to the lower end of the translation plate, the sliding seats being slidably connected to the surface of the fixed rails.

[0009] Furthermore, the calibration assembly includes multiple fixed seats fixedly connected to the upper end of the support plate. The multiple fixed seats are located on both sides of the rectangular hole. The upper end of the fixed seat is provided with an upper groove, and one end of the fixed seat is provided with an inner sliding groove. An abutment rod is slidably connected to the inner wall of the inner sliding groove, and the inner sliding groove communicates with the upper groove.

[0010] Furthermore, a threaded sleeve is provided between the two sliding seats, the threaded sleeve is fixedly connected to the lower end of the translation plate, and the inner wall of the threaded sleeve is threaded with a threaded post.

[0011] Furthermore, a connecting rod is fixedly connected between the two threaded posts, and a rotating handle is fixedly connected to the middle of the surface of the connecting rod, with the rotating handle located above the rectangular hole.

[0012] Furthermore, an arc-shaped pressure block is fixedly connected to the end of the abutment rod away from the fixed base, and adjacent arc-shaped pressure blocks are combined to form a circular tube, which is sleeved on the surface of the rotating handle.

[0013] Furthermore, a horizontal actuating rod is fixedly connected between the abutting rods on one side, with both ends of the horizontal actuating rod penetrating into the interior of the abutting rod. Beneficial effects

[0014] The aforementioned online calibration device for spinning machines can perform centering calibration on the sheet metal being spun under the action of the adjustment mechanism. The device rotates the sheet metal slowly, gradually rotating the rotating handle to drive the threaded column to rotate on the inner wall of the threaded sleeve, causing the sliding seat to move along the fixed rail. The two contact frames contact the sheet metal in sequence, and the sheet metal can be clamped and positioned by the tool clamp. Then, the rotating handle is moved to the center of the calibration component for positioning, reducing the large offset between the center of the sheet metal and the rotation center, and helping to distribute the centrifugal force more evenly when the sheet metal is rotated, thus ensuring the pass rate of the finished product.

[0015] By setting up a calibration component, after the calibration component has clamped the sheet material, the rotating handle can be moved between the two arc-shaped pressure blocks for clamping and alignment. Moving the horizontal lever will cause the abutment rod to drive the arc-shaped pressure blocks to fit against the surface of the rotating handle. At this time, the abutment rod will move linearly under the guidance of the inner slide groove. The arc-shaped pressure blocks on both sides will be fitted onto the surface of the rotating handle, so that the calibration component carries the sheet material towards the center of rotation, ensuring the pass rate of the processed product.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0024] The present invention will be further described below with reference to the embodiments.

[0025] In some embodiments, please refer to the appendix to the instruction manual. Figure 1-4An online calibration device for a spinning machine includes a frame 1, an electric push rod 2 fixedly connected to the inner wall of the frame 1, a rotating seat 11 fixedly connected to the upper end of the frame 1, a contact seat 21 fixedly connected to the telescopic end of the electric push rod 2, the contact seat 21 being slidably connected to the upper end of the frame 1, and an adjustment mechanism 3 installed on the upper end of the frame 1. The adjustment mechanism 3 includes a guide rail 33 installed on the upper end of the frame 1, a support plate 34 slidably connected to the upper end of the guide rail 33, an adjustment component 31 provided on the upper end of the support plate 34, two calibration components 32 provided on the inner side of the adjustment component 31, the calibration components 32 being installed on the upper end of the support plate 34, and a rectangular hole opened on the upper end of the support plate 34.

[0026] In one embodiment of this utility model, when the device is in use, the telescopic end of the drive electric push rod 2 drives the contact seat 21 to move on the upper end of the frame 1, so that the contact seat 21 and the rotating seat 11 initially clamp and position the spun sheet. The support plate 34 moves on the upper end of the guide rail 33 and cooperates with the adjustment component 31 set on the side of the sheet. The drive rotating seat 11 drives the sheet to rotate slowly. At this time, the adjustment component 31 will move horizontally with the sheet. Adjust the adjustment component 31 to contact the edge of the spun sheet. Move the contact seat 21 away from the sheet so that the sheet can move with the adjustment component 31. Move the adjustment component 31 carrying the sheet to the middle of the calibration component 32. Then move the contact seat 21 towards the rotating seat 11 to clamp the sheet.

[0027] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, in a preferred embodiment of the present invention, the adjustment component 31 includes a plurality of fixed rails 311 fixedly connected to the upper end of the support plate 34. A translation plate 312 is slidably connected to the upper end of the fixed rails 311. A plurality of abutment brackets 313 are fixedly connected to the upper end of the translation plate 312. Two sliding seats 314 are fixedly connected to the lower end of the translation plate 312. The sliding seats 314 are slidably connected to the surface of the fixed rails 311. A threaded sleeve 315 is provided between the two sliding seats 314. The threaded sleeve 315 is fixedly connected to the lower end of the translation plate 312. A threaded post 316 is threadedly connected to the inner wall of the threaded sleeve 315. A connecting rod 317 is fixedly connected between the two threaded posts 316. A rotating handle 318 is fixedly connected to the middle of the surface of the connecting rod 317. The rotating handle 318 is located above the rectangular hole.

[0028] In one embodiment of this utility model, rotating the rotating handle 318 causes the connecting rod 317 to rotate accordingly. At this time, the threaded column 316 rotates on the inner wall of the threaded sleeve 315 under the drive of the connecting rod 317. The threaded sleeve 315 drives the translation plate 312 to move horizontally, so that the sliding seat 314 moves along the fixed rail 311. At this time, the two translation plates 312 will move closer to or further away from the two abutting frames 313. When the two abutting frames 313 clamp the plate, the middle part of the rotating handle 318 will move with the plate and be misaligned with the rotation center of the rotating seat 11 in the longitudinal direction. The longitudinal section of the fixed rail 311 is similar to a trapezoid to prevent the sliding seat 314 from easily slipping out. At the same time, the abutting frames 313 on both sides clamp and position the plate. The abutting frames 313 are provided with a colloidal airbag near the surface of the plate.

[0029] In some embodiments, such as Figure 1 , Figure 2 , Figure 4 As shown, in a preferred embodiment of the present invention, the calibration component 32 includes a plurality of fixed seats 321 fixedly connected to the upper end of the support plate 34. The plurality of fixed seats 321 are located on both sides of the rectangular hole. The upper end of the fixed seat 321 is provided with an upper groove 326. One end of the fixed seat 321 is provided with an inner sliding groove 322. The inner wall of the inner sliding groove 322 is slidably connected with a contact rod 323. The inner sliding groove 322 communicates with the upper groove 326. The end of the contact rod 323 away from the fixed seat 321 is fixedly connected with an arc-shaped pressure block 325. Adjacent arc-shaped pressure blocks 325 are combined to form a round tube. The round tube is sleeved on the surface of the rotating handle 318. A horizontal actuating rod 324 is fixedly connected between the contact rods 323 on one side. The two ends of the horizontal actuating rod 324 penetrate into the interior of the contact rod 323.

[0030] In this embodiment of the invention, after the adjustment component 31 clamps the plate, the rotating handle 318 can be moved between the two arc-shaped pressure blocks 325 for clamping and alignment. Moving the horizontal lever 324 will cause the abutment rod 323 to drive the arc-shaped pressure blocks 325 to adhere to the surface of the rotating handle 318. At this time, the abutment rod 323 will move linearly under the guidance of the inner slide groove 322. The arc-shaped pressure blocks 325 on both sides will be sleeved on the surface of the rotating handle 318, so that the adjustment component 31 carries the plate closer to the rotation center. After the plate is clamped by the abutment seat 21 and the rotating seat 11, moving the rotating handle 318 will cause the abutment frames 313 on both sides of the plate to gradually move away, thereby bringing the middle of the plate closer to the rotation center.

[0031] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
