Description

Technical Field

[0001] This invention belongs to the technical field of ball head production and processing of thin-walled hollow tubes, specifically, it relates to a production device for rigid mirror outer tubes. Background Technology

[0002] The rigid endoscope tube is used in the manufacturing process of endoscopes and is one of the essential core components. Currently, the production of the ball head of the rigid endoscope tube is quite complex, requiring specialized metal forming technology and equipment. The conventional method for forming the ball head of a rigid endoscope tube is as follows: 1. Material Preparation: Select 304 stainless steel for the rigid endoscope tube and cut it according to the requirements of the ball head. 2. Pre-treatment: Clean and polish the surface of the rigid endoscope tube to improve the forming effect and surface quality. 3. Clamping: Use clamps to clamp and fix the rigid endoscope tube, ensuring its accurate positioning. 4. Forming: Form the ball head of the rigid endoscope tube through high-temperature heat treatment. Forming method: Spin forming. 5. Shaping: Shape and trim the formed ball head to eliminate any possible defects such as convex corners and textures, and to achieve a smooth, uniform curved surface. 6. Inspection and Adjustment: Inspect the formed ball head, checking its shape, size, surface quality, etc. If necessary, make fine adjustments and corrections to ensure it meets the requirements. In general, the production of the ball head of a rigid mirror outer tube requires the use of professional metal forming technology and equipment, especially forming molds. During the forming process, it is necessary to pay attention to controlling factors such as temperature, pressure and deformation in order to obtain the ideal finished product. The main defects of the existing processing technology are: (1) There are too many uncontrollable factors, such as temperature, pressure and deformation, during the forming process; (2) It is impossible to form the ball head with a tolerance within 0.5mm; (3) The dimensions after forming are unstable, which cannot meet the needs of customers, resulting in a high defect rate.

These outer tubes are then conveyed one by one to the lower end of the material box. Once the outer tubes are in position, the adjustable comb roller stops rotating, and the ball-head forming mechanism is controlled to move towards the end of the outer tube, causing the end of the outer tube to be stamped and formed into a ball head. The ball head is then... As the forming mechanism gradually returns to its original position, the adjustable comb roller continues to rotate, causing the processed hard lens outer tube to be discharged into the receiving box. At the same time, another hard lens outer tube to be processed is conveyed to the lower end of the placement box for the next stamping. In summary, the present invention can continuously stamp the ball head of the hard lens outer tube, effectively reducing uncontrollable factors and unnecessary processes, improving production efficiency. Furthermore, the ball head of the hard lens outer tube produced by stamping has high dimensional accuracy, high pass rate, and low cost, which helps to meet the diverse requirements for hard lens outer tubes.

Detailed Implementation

[0035] The preferred embodiments of the present invention will now be described with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustrative and explanatory purposes only and are not intended to limit the scope of the invention.

[0036] This invention discloses a production apparatus for the outer tube of a rigid endoscope, such as... Figure 1-16As shown, the device includes a material feeding box 100, a receiving box 400, an adjustable combing roller 200, and a ball-head forming mechanism 300. The adjustable combing roller 200 is disposed between the material feeding box 100 and the receiving box 400, and the ball-head forming mechanism 300 is disposed at one axial end of the adjustable combing roller 200. The adjustable combing roller 200 is connected to the outlet of the material feeding box 100 and the inlet of the receiving box. The adjustable combing roller 200 of this invention includes a first transmission mechanism and a second transmission mechanism, which are arranged opposite to each other. A plurality of combing rods 201 are disposed between the first and second transmission mechanisms. These combing rods 201 are evenly arranged along the circumferential direction and form a roller-like structure. Both ends of each combing rod 201 are connected to the first and second transmission mechanisms respectively. The working principle and advantages of this invention are as follows: This invention synchronously drives the first transmission mechanism and the second transmission mechanism to operate, so that the first transmission mechanism drives each comb bar 201 to rotate, and the second transmission mechanism drives all the comb bars 201 to revolve around the roller structure. This causes the comb bars 201 to gradually comb the hard lens outer tubes to be processed in the material box 100, and these hard lens outer tubes to be processed are transported one by one to the lower end of the material box 100, that is, the hard lens outer tubes to be processed are combed to the gap between two adjacent comb bars 201. When the hard lens outer tubes to be processed are in place, the adjustable comb roller 200 is controlled to stop rotating, and the ball head forming mechanism 300 is controlled to move toward the end of the hard lens outer tube to be processed. At this time, the hard lens outer tube to be processed... The tube is confined between two adjacent combing rods 201. The ball-head forming mechanism 300 stamps the end of the hard lens outer tube to be processed, forming a ball head. Then, the ball-head forming mechanism 300 gradually returns to its original position, and the adjustable combing roller 200 continues to rotate, so that the processed hard lens outer tube is discharged into the receiving box 400. At the same time, another hard lens outer tube to be processed is conveyed to the lower end of the placing box 100 for the next stamping. In summary, the present invention can continuously stamp the ball head of the hard lens outer tube, effectively reducing uncontrollable factors and unnecessary processes, improving production efficiency, and producing hard lens outer tubes with high dimensional accuracy, high pass rate, and low cost through stamping, which helps to meet the diverse requirements for hard lens outer tubes.

[0037] As a preferred embodiment of the present invention, such as Figure 2 , 7As shown in Figure 13, the material box 100 includes a vertically arranged box body 101. The box body 101 has a placement cavity 102 with its upper end open. The outer tubes of hard mirrors to be processed are placed in batches in the placement cavity 102. An arc-shaped discharge section 103 is constructed at the lower part of the box body 101. The discharge section 103 is adapted to the corresponding part of the adjustable comb roller 200, and a combing port 104 is opened on the side surface of the discharge section 103 near the adjustable comb roller 200. The combing port 104 extends from one end of the box body 101 to the other end, and the combing port 104 communicates with the lower end of the placement cavity 102. In this embodiment, the ball head forming mechanism 300 is located near the second transmission mechanism. A retaining edge 105 is formed at the end of the discharge section 103 near the first transmission mechanism. The retaining edge 105 extends downward in a curve following the shape of the discharge section 103. In this embodiment, multiple spiral guide lines 202 are formed on the outer circumferential surface of the comb bar 201. These spiral guide lines 202 are evenly arranged along the circumference of the comb bar 201, and each spiral guide line 202 extends spirally along the axis of the comb bar 201 to both ends of the comb bar 201. The working principle and advantages of this embodiment are as follows: Since the comb bar 201 is provided with spiral guide lines 202, during the rotation and revolution of the comb bar 201, the hard lens outer tube to be processed is gradually combed between two adjacent comb bars 201. Under the action of the rotation of the comb bar 201, the spiral guide lines 202 gradually convey the hard lens outer tube to be processed located between the two comb bars 201 towards the flange 105, so that the end of the hard lens outer tube to be processed at the stamping position abuts against the end face of the flange 105. At the same time, under the constraint of the two comb bars 201, the hard lens outer tube to be processed is prevented from deflecting during the stamping process of the ball head forming mechanism 300.

[0038] As a preferred embodiment of the present invention, such as Figure 14 , 15As shown, the ball-head forming mechanism 300 includes a guide rail 301, a ball-head forming mold 302, a connecting pipe 304, and a hydraulic cylinder 305. The guide rail 301 is mounted on the frame and extends axially along the adjustable comb roller 200. The ball-head forming mold 302 is slidably mounted on the guide rail 301. In this embodiment, a ball-head forming hole 303 is provided at the end of the ball-head forming mold 302 near the adjustable comb roller 200. The connecting pipe 304 is detachably mounted at the end of the ball-head forming mold 302 away from the adjustable comb roller 200, and extends along the guide rail 301. In this embodiment, the hydraulic cylinder 305 is located at the end of the connecting pipe 304 away from the ball-head forming mold 302, and one end of the hydraulic rod 306 of the hydraulic cylinder 305 extends into the insertion cavity 308 of the connecting pipe 304. A buffer spring 307 is fitted around the hydraulic cylinder 305 outside the connecting pipe 304. The two ends of the buffer spring 307 are connected to the hydraulic cylinder 305 and the connecting pipe 304, respectively. The working principle and advantages of this embodiment are as follows: When the hard lens outer tube to be processed is conveyed to the position by the adjustable comb roller 200, the end of the hard lens outer tube to be processed is aligned with the ball head forming hole 303 on the ball head forming mold 302. The hydraulic cylinder 305 is then controlled to drive the connecting pipe 304, causing the ball head forming mold 302 to slide along the guide rail 301. This allows the ball head forming mold 302 to gradually move closer to the hard lens outer tube to be processed. When the end of the hard lens outer tube extends into the ball head forming hole 303 of the ball head forming mold 302... After 3 seconds, the outer tube of the hard lens to be processed contacts the end of the ball-head forming hole 303, causing the ball-head forming die 302 to stop, and the connecting pipe 304 also stops moving. At this time, the hydraulic cylinder 305 continues to move. In this way, the buffer spring 307 is gradually compressed and stores energy, and drives the ball-head forming die 302 to continue moving towards the outer tube of the hard lens to be processed through the connecting pipe 304 until the end of the outer tube of the hard lens to be processed forms a ball. After the forming is completed, the hydraulic cylinder 305 is controlled to drive the ball-head forming die 302 to return to its original position. In this embodiment, the buffer spring 307 is used to achieve the purpose of buffered stamping of the outer tube of the hard lens to be processed, avoiding hard contact between the ball-head forming die 302 and the outer tube of the hard lens to be processed, thereby preventing damage, deformation, and breakage of the end of the hard lens outer tube due to hard stamping.

[0039] As a preferred embodiment of the present invention, such as Figure 16As shown, the receiving box 400 includes an integrally formed guiding section 401 and a collecting section 402. The guiding section 401 has a guiding cavity, and the collecting section 402 has a collecting cavity; the guiding cavity and the collecting cavity are interconnected. The end of the guiding section 401 away from the collecting section 402 is connected to the stamping station at the lower end of the adjustable comb roller 200, and the guiding cavity gradually slopes downwards towards the collecting cavity. The hard mirror outer tube, stamped by the ball-head forming mechanism 300, is conveyed into the guiding cavity as the adjustable comb roller 200 rotates, and gradually rolls downwards from the bottom wall of the guiding cavity into the collecting cavity.

[0040] As a preferred embodiment of the present invention, such as Figure 8 , 9 As shown, the first transmission mechanism includes a first mounting base 218, a first mounting disc 212, a drive gear 222, a first drive rod 213, and a first transmission sprocket 214. The first mounting disc 212 is rotatably mounted on the first mounting base 218 via a mounting ring 233. Each comb bar 201 has its end near the first mounting base 218 rotatably connected to the first mounting disc 212. The drive gear 222 is rotatably mounted on the first mounting disc 212, and its axis coincides with that of the first mounting disc 212. In this embodiment, the first drive rod 213 moves along the axis of the drive gear 222, passing through it. A transmission gear 207 is mounted at the end of each comb bar 201 near the first mounting base 218, and the first transmission sprocket 214 is coaxially mounted on the first drive rod 213. Figure 10 , 11 As shown, the second transmission mechanism includes a second mounting base 229, a second mounting disc 223, a second drive rod 224, and a second transmission sprocket 225. The second mounting disc 223 is rotatably mounted on the second mounting base 229 via another mounting ring 233. One end of each comb bar 201 near the second mounting base 229 is rotatably connected to the second mounting disc 223. The second drive rod 224 moves along the axis of the second mounting base 229, passing through it, and the second transmission sprocket 225 is mounted on the second drive rod 224. In this embodiment, the axes of the mounting ring 233, the first mounting disc 212, and the second mounting disc 223 coincide, as shown... Figure 12As shown, an annular groove 234 is constructed on the inner peripheral wall of the assembly ring 233, and the first assembly disc 212 and the second assembly disc 223 are respectively assembled into the annular groove 234 of the corresponding assembly ring 233. Two connecting ears 235 are symmetrically constructed on the outer peripheral surface of the assembly ring 233, and these two connecting ears 235 are connected to the corresponding first assembly seat 218 or second assembly seat 229; moreover, in order to facilitate the assembly and disassembly of the assembly ring 233 from the first assembly seat 218 or the second assembly seat 229, the assembly ring 233 adopts a split structure. The working principle and advantages of this embodiment are as follows: The first drive rod 213 and the second drive rod 224 are synchronously driven to rotate. The first drive rod 213 drives the drive gear 222 to rotate, and during this rotation, the drive gear 222 drives all the transmission gears 207 to rotate, thereby driving each comb bar 201 to rotate. Simultaneously, the second drive rod 224 drives the second assembly disc 223 to rotate, and the second assembly disc 223 drives all the comb bars 201 to revolve along the axis of the second drive rod 224. Furthermore, the direction of rotation of the second assembly disc 223 is... Figure 3 The comb bar 201 rotates clockwise while the comb bar 201 rotates counterclockwise. In this embodiment, during the synchronized revolution and rotation of the comb bar 201, the adjustable comb roller 200 gradually conveys the hard lens outer tube to be processed, located at the comb opening 104, downwards along the arc of the discharge section 103, so that the hard lens outer tube to be processed gradually arranges itself in the gap between corresponding adjacent comb bars 201, thereby achieving the purpose of feeding the hard lens outer tube to be processed one by one. Moreover, since the hard lens outer tubes to be processed located between adjacent comb bars 201 are uneven, during the rotation of the comb bar 201, under the action of the spiral guide 202, the end of the hard lens outer tube to be processed gradually approaches the stop 105 until it abuts against the inner end face of the stop 105, thereby avoiding relative sliding or skew of the ball head forming mechanism 300 during the stamping process, thus ensuring the quality of the stamped product.

[0041] As a preferred embodiment of the present invention, such as Figure 5-11As shown, a first universal joint assembly and a second universal joint assembly are connected to both ends of each comb bar 201. The ends of the first and second universal joint assemblies that are close to each other are connected to the comb bar 201, while the ends that are far apart are connected to the first shaft 206 and the second shaft 211, respectively. The axes of the first shaft 206 and the second shaft 211 coincide and are parallel to the axis of the comb bar 201. Each of the aforementioned transmission gears 207 is coaxially mounted on the corresponding first shaft 206. A first adjustment assembly and a second adjustment assembly are provided between the first assembly plate 212 and the second assembly plate 223. The first adjustment assembly is rotatably connected to the end of the first drive rod 213, and the second adjustment assembly is rotatably or fixedly connected to the end of the second drive rod 224. The specific structure of the first universal joint assembly in this embodiment is as follows: the first universal joint assembly includes a first universal coupling 203 and a second universal coupling 204.

The end of the second universal coupling 204 away from the first universal coupling 203 is connected to the first shaft 206. The second universal joint assembly has the following structure: it includes a third universal joint 208 and a fourth universal joint 209. The ends of the third universal joint 208 and the fourth universal joint 209 that are close to each other are connected by a second connecting rod 210. The radial cross-section of the second connecting rod 210 is a regular polygon. The end of the third universal joint 208 that is close to the second connecting rod 210 has a slot with a regular polygonal cross-section.

The specific structure of the first adjustment component is as follows: the first adjustment component includes a first hinge plate 215, the axis of which coincides with the axis of the first drive rod 213. A plurality of first hinge rods 216 are evenly hinged around the first hinge plate 215.

The second adapter sleeve 228 is rotatably connected to the other end of the corresponding comb rod 201. A second adjustment member is connected to the end of the second drive rod 224 away from the second hinge plate 226. The working principle and advantages of this embodiment are as follows: Since the diameter of the rigid lens outer tube can be divided into various types, when it is necessary to stamp a corresponding model of rigid lens outer tube to be processed, it is necessary to adjust the gap between adjacent comb rods 201 so that the corresponding model of rigid lens outer tube to be processed can fit within the aforementioned gap. The specific adjustment method is as follows: the first and second adjusting components are controlled synchronously so that the first drive rod 213 and the second drive rod 224 move closer or further away simultaneously. In this way, the first drive rod 213 and the second drive rod 224 drive the first hinge plate 215 and the second hinge plate 226 to move respectively. During the process of the first hinge plate 215 and the second hinge plate 226 moving closer or further away from each other, the first hinge plate 215 drives all the first hinge rods 216 to contract or expand, and the second hinge plate 226 drives all the second hinge rods 227 to contract or expand. This causes all the comb rods 201 to converge or expand, thereby making the gap between adjacent comb rods 201 smaller or larger, thus adapting to the corresponding model of hard lens outer tube and ensuring the conveying, positioning and subsequent stamping operation of the hard lens outer tube of this model.

[0042] As a preferred embodiment of the present invention, such as Figure 8 As shown, the first adjusting component includes a first rotating seat 219, a first adjusting screw 220, and a first locking nut 221. The first rotating seat 219 is rotatably connected to the corresponding end of the first drive rod 213. One end of the first adjusting screw 220 is fixedly connected to the first rotating seat 219. The axis of the first adjusting screw 220 coincides with the axis of the first drive rod 213, and the first adjusting screw 220 extends out of the first mounting base 218. The first adjusting screw 220 is threadedly connected to the first mounting base 218. The first locking nut 221 is threadedly connected to the first adjusting screw 220 and is locked onto the first mounting base 218. Figure 10As shown, the second adjusting component includes a second rotating seat 230, a second adjusting screw 231, and a second locking nut 232. The second rotating seat 230 is rotatably connected to the corresponding end of the second drive rod 224. The second adjusting screw 231 is fixedly connected to the second rotating seat 230, and the axis of the second adjusting screw 231 coincides with the axis of the second drive rod 224. The second adjusting screw 231 extends out of the second mounting base 229 and is threadedly connected to the second mounting base 229. In this embodiment, the second locking nut 232 is threadedly connected to the second adjusting screw 231, and the second locking nut 232 is locked onto the second mounting base 229. The working principle of this embodiment is as follows: When it is necessary to adjust the gap between adjacent comb rods 201, loosen the first locking nut 221 and the second locking nut 232, and then rotate the first adjusting screw 220 and the second adjusting screw 231 simultaneously, so that the two respectively drive the first driving rod 213 and the second driving rod 224 to move closer or further away from each other, thereby causing the first driving rod 213 and the second driving rod 224 to drive the first adjusting component and the second adjusting component to move, so that the first adjusting component and the second adjusting component drive all the comb rods 201 to gather together or spread outward, thereby realizing the adjustment of the gap between adjacent comb rods 201.
