Description

Technical Field

[0001] This invention belongs to the field of eyeglasses technology, and relates to an assembly device for eyeglasses components, particularly a spring core assembly device. Background Technology

[0002] As is well known, flexible temples have the following characteristics: When worn, the flexible temples can be bent outwards at a certain angle, opening the outer ends of the temples for the user to wear. When the temples are released, the outer ends of the two temples come together due to the elastic force of the spring, thus ensuring that the glasses are securely worn on the user's head.

[0003] In elastic eyeglass temples, the temple body is hinged to a hinge via a spring core. A typical spring core consists of a core body and a grooved tube, a helical compression spring, and a sealing tube sequentially assembled onto a guide rod of the core body. The assembly process of a spring core in the prior art is illustrated in patent number "200610052052.9," entitled "Manufacturing Method of Spring Core for Elastic Eyeglass Temples." This patent describes a spring core comprising a core body, a grooved tube, a helical compression spring, and a sealing tube. The grooved tube, helical compression spring, and sealing tube are sequentially assembled onto the guide rod of the core body. The assembled spring core is then placed in a fixture and pushed to a limiting point. Finally, the lower end of the core body guide rod is flattened or rounded on a small punch press to form a stop at the tail of the spring core, thus obtaining the elastic eyeglass temple spring core. Because the process of flattening or rounding the lower end of the core body guide rod by the punch press in the existing technology is uncontrollable, the shape and thickness of the resulting stop cannot be kept consistent. More importantly, the flatness of the bottom surface of the stop is low. If the end of the spring is directly in contact with the stop, it will cause uneven force on the spring and the spring will be easily deformed by compression. Therefore, in the existing technology, a small sealing tube must be added to the tail of the spring as a shim to ensure that the spring is normally stressed. However, the addition of the sealing tube also makes the entire spring core longer and the strength after assembly poor. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned problems in the prior art by providing a spring core assembly device that ensures a smooth and flat bottom surface after the limiting block is formed, allowing it to directly fit against the spring end face.

[0005] The objective of this invention can be achieved through the following technical solution: A spring core assembly device includes a fixed base, a first pressing cylinder, a pressing rod, a second pressing cylinder, and a positioning mechanism. The fixed base has a fixing groove, in which a core body is placed. A spring is sleeved on the guide rod of the core body. The positioning mechanism includes a first positioning cylinder and two positioning clamps. The positioning clamps have positioning grooves. The first positioning cylinder drives the two positioning clamps to move towards each other. The second pressing cylinder drives the positioning mechanism to move downward. During the downward movement of the positioning clamps, the spring is squeezed. The pressing rod is located directly above the guide rod. The first pressing cylinder drives the pressing rod to move downward. The upper surfaces of the pressing rod and the positioning clamps cooperate to form a limiting block at the end of the guide rod. The diameter of the limiting block is larger than the inner diameter of the spring end, so that both ends of the spring can contact the core body and the limiting block respectively.

[0006] In the above-mentioned spring core assembly device, the piston rod of the first positioning cylinder is connected to a rack. The positioning mechanism also includes a gear, two guide blocks and a positioning base. The gear meshes with the rack. The piston rod of the first positioning cylinder extends to drive the rack to move. The movement of the rack drives the gear to rotate. The height of the rack is greater than the height of the gear, so that the gear always meshes with the rack during the up-and-down movement.

[0007] In the above-mentioned spring core assembly device, the positioning base has a moving channel, and the two positioning clamps are arranged opposite to each other in the moving channel. The two positioning clamps can move relative to each other or back to back in the moving channel. The center of the positioning base has a through-hole, and the end of the guide rod enters the through-hole and is located in the moving channel.

[0008] In the above-mentioned spring core assembly device, the top of the positioning base is provided with an insertion block, the gear is sleeved on the insertion block, the gear is provided with two arc-shaped grooves, the guide block is arc-shaped and embedded in the arc-shaped grooves, after the guide block is installed, one end of the guide block away from the center of the positioning base is set as the open end, and the other end of the guide block near the center of the positioning base is set as the clamping end, the end of the positioning clamping block is provided with a guide groove, and the bottom of the guide block is provided with a guide flange, the guide flange is inserted into the guide groove and can slide in the guide groove, when the gear rotates and drives the guide flange to rotate synchronously, the guide flange drives the two positioning clamping blocks to move relative to each other or in opposite directions in the moving channel.

[0009] In the above-mentioned spring core assembly device, the positioning mechanism further includes a positioning cover, which is mounted on the gear and fixed to the positioning base. The positioning cover has a through hole for the pressure rod to pass through, and the piston rod of the second pressing cylinder is connected to the positioning cover.

[0010] In the above-mentioned spring core assembly device, the positioning mechanism further includes a second positioning cylinder, which is arranged opposite to the first positioning cylinder. The piston rod of the second positioning cylinder extends towards the first positioning cylinder. During the movement of the rack, when the rack contacts the piston rod of the second positioning cylinder, the rack stops moving.

[0011] The aforementioned spring core assembly device further includes a mounting block. The mounting block has a movable cavity, and the bottom and top of the movable cavity are provided with movable slide rails. The side of the movable cavity has an engagement opening. The rack is slidably disposed in the movable cavity, and the teeth on the rack protrude from the engagement opening. The bottom and top of the rack are provided with movable grooves, and the movable slide rails are located in the movable grooves. The side of the mounting block is arc-shaped. The first positioning cylinder and the second positioning cylinder are respectively installed on both sides of the mounting block.

[0012] In the above-described spring core assembly device, the first pressing cylinder is installed on the top of the mounting block, and the pressing rod is connected to the piston rod of the first pressing cylinder; the second pressing cylinder is installed on the top of the first pressing cylinder, and the piston rod of the second pressing cylinder passes through the first pressing cylinder and is fixed to the positioning mechanism.

[0013] The aforementioned spring core assembly device also includes a mounting base. The mounting base has an adjustment groove, and a first adjustment block is provided in the adjustment groove. The first adjustment block can move back and forth within the adjustment groove. A second adjustment block is fixed on the first adjustment block and is perpendicular to the first adjustment block. The mounting block is located on the mounting base and can move relative to the mounting base. An adjustment groove is provided at the bottom of the mounting block, and the second adjustment block is located within the adjustment groove. Limiting baffles are also provided on both sides of the mounting base to limit the movement of the mounting block.

[0014] In the above-mentioned spring core assembly device, an adjustment seat is also installed on the side of the mounting base. An adjustment screw is installed on the adjustment seat, and an adjustment insert is threaded to the end of the adjustment screw. An insert groove is also formed at the bottom of the mounting block. The adjustment insert is inserted into the insert groove. By rotating the adjustment screw, the adjustment insert moves back and forth on the adjustment screw. The adjustment insert drives the mounting block and the first adjustment block to move relative to the mounting base.

[0015] Compared with existing technologies, the upper surfaces of the pressure rod and the positioning clamping block in this spring core assembly device ensure that the thickness and shape of the formed limiting block are uniform. Furthermore, the bottom surface of the limiting block contacts the upper surface of the positioning clamping block during forming, ensuring a smooth and flat bottom surface that can directly fit against the spring end face. This guarantees uniform spring force, reduces spring deformation, and eliminates the need for the end-capping tube found in existing technologies, shortening the spring core length and increasing overall assembly strength. The positioning clamping block positions the guide rod, preventing it from wobbling and ensuring stable forming of the limiting block. A rack, gear, and guide block enable a first positioning cylinder to simultaneously move two positioning clamping blocks, ensuring synchronized movement and smooth, stable operation of subsequent spring compression and guide rod clamping. A second positioning cylinder positions the rack and also the relative movement of the two positioning clamping blocks. The mounting block can move laterally and vertically on the mounting base, allowing adjustment of the mounting position of the mounting block and rack, ensuring the rack is always engaged with the gear.

[0023] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0024] like Figure 1-6As shown, this spring core assembly device includes a fixed base 1, a first pressing cylinder 2, a pressing rod 3, a second pressing cylinder 6, and a positioning mechanism 4. The fixed base 1 has a fixing groove, in which the core body 5 is placed. A spring 52 is sleeved on the guide rod 51 of the core body 5. The positioning mechanism 4 includes a first positioning cylinder 41 and two positioning clamps 42, each with a positioning groove 422. The first positioning cylinder 41 drives the two positioning clamps 42 to move towards each other, making the space between the two positioning grooves 422 larger than the diameter of the guide rod 51 but smaller than the diameter of the end of the spring 52. The second pressing cylinder 6 drives the positioning mechanism 4 to move downwards, and the positioning clamps 42 compress the spring 52 during this downward movement. The first positioning cylinder 41 again drives the two positioning clamps 42 to move towards each other, causing the two positioning clamps 42 to clamp the guide rod 51. The pressure rod 3 is located directly above the guide rod 51. The first pressing cylinder 2 drives the pressure rod 3 to move downward. The upper surfaces of the pressure rod 3 and the positioning clamps 42 cooperate to round the end of the guide rod 51 into a limiting block 53. The diameter of the limiting block 53 is larger than the inner diameter of the end of the spring 52. Finally, the first pressing cylinder 2 drives the pressure rod 3 to move upward. The first positioning cylinder 41 drives the two positioning clamps 42 to disengage from the guide rod 51. The spring 52 releases its elasticity, and both ends of the spring 52 contact the core body 5 and the limiting block 53 respectively, removing the spring core from the fixing groove and completing the automatic assembly of the spring core. Because the second pressing cylinder 6 drives the positioning mechanism 4 to move down by a fixed amount, and the first pressing cylinder 2 drives the pressure rod 3 to move down by a fixed amount, the upper surfaces of the pressure rod 3 and the positioning clamp 42 cooperate to ensure that the thickness and shape of the formed limiting block 53 are uniform. Furthermore, the bottom surface of the limiting block 53 contacts the upper surface of the positioning clamp 42 during forming, ensuring that the bottom surface of the limiting block 53 is smooth and flat after forming, allowing it to directly fit against the end face of the spring 52. This ensures that the spring 52 is subjected to uniform force, reduces spring 52 deformation, and also reduces the need for the end cap tube in existing technologies, shortens the length of the spring core, and increases the overall strength after assembly. The positioning clamp 42 clamps the guide rod 51 to position it, ensuring that the guide rod 51 does not wobble, thereby ensuring the stable forming of the limiting block 53.

[0025] In the above technical solution: the piston rod of the first positioning cylinder 41 is connected to a rack 44. The positioning mechanism 4 also includes a gear 45, two guide blocks 46, a positioning cover 47, and a positioning base 48. The gear 45 meshes with the rack 44. The extension of the piston rod of the first positioning cylinder 41 drives the rack 44 to move, and the movement of the rack 44 drives the gear 45 to rotate. The height of the rack 44 is greater than the height of the gear 45, so that the gear 45 is always meshed with the rack 44 during its up-and-down movement.

[0026] In the above technical solution: a moving channel 481 is formed on the positioning base 48, and two positioning clamps 42 are arranged opposite each other in the moving channel 481. The two positioning clamps 42 can move relative to each other or move away from each other in the moving channel 481. A machining hole 482 is formed through the center of the positioning base 48, and the end of the guide rod 51 enters the machining hole 482 and is located in the moving channel 481.

[0027] In the above technical solution: an insertion block 483 is formed at the top center of the positioning base 48, and the gear 45 is sleeved on the insertion block 483 to ensure the concentricity of the gear 45 and the positioning base 48. Two arc-shaped grooves 451 are formed on the gear 45, and the guide block 46 is arc-shaped and embedded in the arc-shaped grooves 451. Figure 4 As shown, after the guide block 46 is installed, one end of the guide block 46 away from the center of the positioning base 48 is set as the opening end 462, and the other end of the guide block 46 near the center of the positioning base 48 is set as the clamping end 463. The two guide blocks 46 are set in opposite directions. The end of the positioning clamping block 42 is provided with a guide groove 421, and the bottom of the guide block 46 is provided with a guide flange 461. The guide flange 461 is inserted into the guide groove 421 and can slide in the guide groove 421. When the gear 45 rotates and drives the guide flange 461 to rotate synchronously, the guide flange 461 drives the two positioning clamping blocks 42 to move relative to each other or in opposite directions in the moving channel 481. The positioning cover 47 is placed on the gear 45 and fixed to the positioning base 48. The positioning cover 47 is provided with a through hole for the pressure rod 3 to pass through. The rack 44, gear 45, and guide block 46 enable the first positioning cylinder 41 to simultaneously drive the two positioning clamping blocks 42 to move, ensuring that the movement between the two positioning clamping blocks 42 is synchronized, thereby ensuring the smooth and stable operation of the subsequent compression spring 52 and clamping guide rod 51.

[0028] In the above technical solution, the positioning mechanism 4 further includes a second positioning cylinder 43, which is arranged opposite to the first positioning cylinder 41. The piston rod of the second positioning cylinder 43 extends a certain length towards the first positioning cylinder 41. During the movement of the rack 44, when the rack 44 contacts the piston rod of the second positioning cylinder 43, the rack 44 stops moving. The second positioning cylinder 43 positions the movement of the rack 44, and at the same time positions the relative movement of the two positioning blocks 42.

[0029] The above technical solution also includes a mounting block 8, which has a movable cavity 81. Movable slide rails 82 are formed at the bottom and top of the movable cavity 81, and meshing openings 83 are formed on the side of the movable cavity 81. A rack 44 is slidably disposed within the movable cavity 81, with the teeth of the rack 44 protruding from the meshing openings 83. Movable slide grooves are formed at the bottom and top of the rack 44, and the movable slide rails 82 are located within the slide grooves. The side of the mounting block 8 is rounded to prevent interference with the gear 45. A first positioning cylinder 41 and a second positioning cylinder 43 are respectively mounted on both sides of the mounting block 8.

[0030] The above technical solution also includes a mounting base 7, which has an adjustment groove 71. A first adjustment block 72 is provided within the adjustment groove 71 and can move back and forth within it. A second adjustment block 73 is fixed to the first adjustment block 72 and is perpendicular to it. A mounting block 8 is located on the mounting base 7 and can move relative to it. An adjustment groove 84 is provided at the bottom of the mounting block 8, and the second adjustment block 73 is located within it. The adjustment groove 84 and the second adjustment block 73 cooperate to guide the lateral movement of the mounting block 8 on the mounting base 7. Limiting baffles 77 are also provided on both sides of the mounting base 7 to limit the lateral movement of the mounting block 8. The ability of the mounting block 8 to move laterally on the mounting base 7 allows for adjustment of its lateral mounting position, facilitating better cooperation with the gear 45, the second positioning cylinder 43, and the first positioning cylinder 41.

[0031] In the above technical solution: an adjusting seat 74 is also installed on the side of the mounting base 7, and an adjusting screw 75 is installed on the adjusting seat 74. An adjusting insert 76 is threaded to the end of the adjusting screw 75. An insert groove is also formed at the bottom of the mounting block 8, and the adjusting insert 76 is inserted into the insert groove. Rotating the adjusting screw 75 causes the adjusting insert 76 to move back and forth on the adjusting screw 75, thereby causing the adjusting insert 76 to drive the mounting block 8 and the first adjusting block 72 to move vertically relative to the mounting base 7, thereby adjusting the installation position of the rack 44 and ensuring that the rack 44 is always engaged with the gear 45.

[0032] In the above technical solution: the first pressing cylinder 2 is installed on the top of the mounting block 8, and the pressing rod 3 is connected to the piston rod of the first pressing cylinder 2; the second pressing cylinder 6 is installed on the top of the first pressing cylinder 2, and the piston rod of the second pressing cylinder 6 passes through the first pressing cylinder 2 and is fixed to the positioning cover 47 in the positioning mechanism 4; thereby realizing that the second pressing cylinder 6 drives the positioning mechanism 4 to move up and down, and the first pressing cylinder 2 drives the pressing rod 3 to move up and down, and the movement processes are independent of each other and do not interfere with each other.

[0033] The working process of this invention is as follows: First, the piston rod of the second positioning cylinder 43 is extended a certain length towards the first positioning cylinder 41. The extension of the piston rod of the first positioning cylinder 41 drives the rack 44 to move. At the same time, the rack 44 drives the gear 45 to rotate clockwise, causing the guide flange 461 to move from the open end 462 towards the gripping end 463 within the guide groove 421. Since the gripping end 463 is closer to the center of the positioning base 48 than the open end 462, the movement of the guide flange 461 drives the positioning clamp... Block 42 moves toward the machining hole 482, that is, the guide flange 461 drives the two positioning blocks 42 to move relative to each other in the moving channel 481; until the rack 22 contacts the piston rod of the second positioning cylinder 43, the rack 22 stops moving, the gear 45 stops rotating, and the positioning blocks 42 also stop moving. At this time, the space between the two positioning grooves 422 is greater than the diameter of the guide rod 51 and less than the diameter of the end of the spring 52. The second pressing cylinder 6 drives the positioning mechanism 4 to move down, and the positioning blocks 42 squeeze the spring 52 during the downward movement.

[0034] Next, the piston rod of the second positioning cylinder 43 shortens by a certain length in a direction away from the first positioning cylinder 41. The first positioning cylinder 41 then drives the piston rod of 41 to extend, causing the rack 44 to move. At the same time, the rack 44 drives the gear 45 to continue rotating clockwise. The guide flange 461 drives the two positioning clamps 42 to continue moving relative to each other within the moving channel 481. Until the rack 22 contacts the piston rod of the second positioning cylinder 43 again, the rack 22 stops moving, the gear 45 stops rotating, and the positioning clamps 42 also stop moving. At this time, the clamping end 463 moves into the guide groove 421, as shown. Figure 4 As shown, two positioning clamps 42 grip the guide rod 51. Finally, the first pressing cylinder 2 drives the pressure rod 3 to move downward. The upper surfaces of the pressure rod 3 and the positioning clamps 42 cooperate to round the end of the guide rod 51 into a limiting block 53. The diameter of the limiting block 53 is larger than the inner diameter of the end of the spring 52. Finally, the first pressing cylinder 2 drives the pressure rod 3 to move upward. The first positioning cylinder 41 drives the two positioning clamps 42 to disengage from the guide rod 51. The two ends of the spring 52 contact the core body 5 and the limiting block 53 respectively, removing the spring core from the fixing groove and completing the automatic assembly of the spring core.

[0035] In this spring core assembly device, the limiting block 53, formed by the upper surfaces of the pressure rod 3 and the positioning clamp 42, has a uniform thickness and shape. Furthermore, the bottom surface of the limiting block 53 contacts the upper surface of the positioning clamp 42 during forming, ensuring a smooth and flat bottom surface that can directly fit against the end face of the spring 52. This ensures uniform force distribution on the spring 52, reduces spring deformation, and eliminates the need for the end-capping tube found in existing technologies, shortening the spring core length and increasing overall assembly strength. The positioning clamp 42 clamps and positions the guide rod 51, preventing it from wobbling and thus ensuring the limiting block's position. Positioning block 53 is stably formed; the rack 44, gear 45, and guide block 46 enable a first positioning cylinder 41 to simultaneously drive two positioning clamping blocks 42 to move, ensuring synchronous movement between the two positioning clamping blocks 42, thereby ensuring smooth and stable operation of the subsequent compression spring 52 and clamping guide rod 51; the second positioning cylinder 43 positions the movement of the rack 44, and also positions the relative movement of the two positioning clamping blocks 42; the mounting block 8 can move laterally and vertically on the mounting base 7, allowing the mounting positions of the mounting block 8 and rack 44 to be adjusted, ensuring that the rack 44 is always meshed with the gear 45.
