Description

Technical Field

[0001] The present invention belongs to the technical field of accessory processing, and specifically relates to a two-way centering processing device for injection-molded accessories of an optical lens. Background Technique

[0002] Optical lenses are essential components in machine vision systems, directly affecting the quality of imaging and the implementation and effect of algorithms. Optical lenses can be divided into short-focus lenses, medium-focus lenses, and long-focus lenses according to their focal lengths.

[0003] There are some injection-molded accessories on the optical lens, and these accessories often need to grind the burrs on their surfaces during injection molding. Before grinding, it is necessary to first use clamping equipment to clamp and fix the accessories to facilitate subsequent grinding work.

[0004] Two-way centering means automatically adjusting the position of the workpiece through symmetric two-way clamping mechanisms so that its axis is precisely aligned with the center of the fixture. For example, a two-way threaded structure of a lead screw can drive the jaws on both sides to move synchronously to ensure that the workpiece is always at the center of the fixture during clamping.

[0005] However, traditional two-way centering fixtures often lack multiple clamping methods, resulting in a reduced adaptability of the device. Summary of the Invention

[0006] To solve the problem of lacking multiple clamping methods proposed in the above background technique, the present invention provides a two-way centering processing device for injection-molded accessories of an optical lens.

[0007] To achieve the above object, the present invention provides the following technical solution: A two-way centering processing device for injection-molded accessories of an optical lens, including a rectangular housing and two first circular plates located outside the rectangular housing. Four linearly arranged grooves equally spaced in a circumferential manner are provided on one side of each of the two first circular plates close to each other. A long rod is slidably connected in each linearly arranged groove, and a first clamping plate is fixedly connected to the free end of each long rod. A second clamping plate is rotatably connected to one side of the first clamping plate. A two-way centering mechanism for driving the two first circular plates to move horizontally is provided inside the rectangular housing. A changing component for driving the second clamping plate to rotate to different angles is provided on the first clamping plate. An adjusting mechanism for driving the first clamping plate and the second clamping plate to move along the linearly arranged grooves is provided inside the rectangular housing.

[0008] Preferably, the two-way centering mechanism includes two threaded rods rotatably connected and coaxially fixed inside the rectangular housing. The two threaded rods are symmetrically distributed and have opposite thread directions on their surfaces. Inner threaded sleeves threadedly connected to the two threaded rods are sleeved on both of the threaded rods.

[0009] Preferably, the rectangular housing is provided with limiting grooves parallel to the threaded rod on its surface. Fixedly connected to the surfaces of the two internal thread sleeves are L-shaped rods that extend to the outside of the rectangular housing through the limiting grooves. Fixedly connected to the end of the L-shaped rod away from the internal thread sleeve is a U-shaped seat, and the two first circular plates are respectively fixed on the two U-shaped seats.

[0010] Preferably, the adjusting mechanism includes a second circular plate rotatably connected to the first circular plate, and a worm gear coaxially fixed to the second circular plate. The surface of the second circular plate is provided with an arc-shaped groove adapted to the long rod. The two side walls of the U-shaped seat are penetrated by a first circular shaft rotatably connected thereto, and a worm engaged with the worm gear is sleeved on the first circular shaft.

[0011] Preferably, two symmetrically distributed rectangular frames are arranged inside the rectangular housing. The two opposite side walls of the rectangular frame are penetrated by an external spline shaft rotatably connected thereto, and a first bevel gear fixedly connected thereto and located inside the rectangular frame is sleeved on the external spline shaft.

[0012] Preferably, an internal spline shaft parallel to the threaded rod is rotatably connected inside the rectangular housing. The internal spline shaft passes through the external spline shaft and is adapted to the external spline shaft. The surface of the rectangular housing is provided with a strip-shaped groove parallel to the internal spline shaft.

[0013] Preferably, the two first circular shafts both extend into the rectangular housing through the strip-shaped groove, and respectively penetrate the side walls of the two rectangular frames and then extend into the rectangular frames. The first circular shaft is rotatably connected to the rectangular frame. A second bevel gear fixedly connected thereto is sleeved on the end of the first circular shaft located inside the rectangular frame, and the second bevel gear meshes with the first bevel gear.

[0014] Preferably, the changing assembly includes a second circular shaft penetrating through the first clamping plate and rotatably connected to the first clamping plate. The second clamping plate is sleeved on the second circular shaft and fixedly connected to the second circular shaft. An annular sleeve fixedly connected thereto is sleeved on one end of the second circular shaft. Two symmetrically distributed rectangular seats are fixedly connected to the surface of the annular sleeve. Spring rods are fixedly connected to the two rectangular seats, and ratchet teeth are fixedly connected to the free ends of the spring rods.

[0015] Preferably, a hollow shaft is rotatably connected to the side wall of the first clamping plate. A ratchet wheel is fixedly connected to the inner wall of the hollow shaft. The ratchet wheel meshes with the two ratchet teeth. A gear fixedly connected thereto is sleeved on the surface of the hollow shaft. A bent rod is fixedly connected to the side wall of the first circular plate, and a rack is fixedly connected to the free end of the bent rod.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: By setting up a two-way centering mechanism, it is possible to drive the two first circular plates to move towards each other or away from each other. The first circular plate can drive the first clamping plate and the second clamping plate to move accordingly through a long rod. When the first clamping plates and the second clamping plates on both sides move towards each other, the fitting to be processed can be clamped.

[0017] By setting up a variation component, it is possible to drive the second clamping plate to rotate to different angles. When the second clamping plate and the first clamping plate are in a perpendicular state, it is possible to clamp and position a cylindrical fitting. This can not only make the central axis of the fitting coincide with the central axis of the rectangular housing, but also lock the center position of the fitting to be on the same horizontal line as the center position of the first circular plate, as Figure 1 shown.

[0018] When a cylindrical fitting or other shaped fittings do not require the center position to be locked to the same horizontal line as the center of the first circular plate, the second clamping plate can be rotated into the movable groove on the surface of the first clamping plate so that the second clamping plate and the first clamping plate are in a coincident state, as Figure 4 shown.

[0019] When the second clamping plate and the first clamping plate are in an obtuse angle state, as Figure 5 shown, the four first clamping plates and the second clamping plates on the same horizontal plane can clamp and fix a disc-shaped fitting, making the disc-shaped fitting parallel to the ground. And the other four first clamping plates and the second clamping plates can also clamp and fix the disc-shaped fitting, making the disc-shaped fitting perpendicular to the ground. By setting up an adjustment mechanism, it is possible to drive the first clamping plate and the second clamping plate to move towards the center position of the first circular plate or away from the center position of the first circular plate.

Detailed implementation manners

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] As Figures 1 to 3 shown, the present invention provides a two-way centering processing device for optical lens injection molding accessories, including a rectangular outer shell 1 and two first circular plates 21 located outside the rectangular outer shell 1. Four linearly arranged grooves 22 that are equally spaced in a circular pattern are provided on one side of each of the two first circular plates 21 that are close to each other. A long rod 23 is slidably connected in each linear groove 22, and a first clamping plate 31 is fixedly connected to the free end of each long rod 23. A second clamping plate 32 is rotatably connected to one side of the first clamping plate 31.

[0024] A two-way centering mechanism for driving two first circular plates 21 to move horizontally is provided inside the rectangular housing 1.

[0025] By providing the two-way centering mechanism, the two first circular plates 21 can be driven to move towards each other or away from each other. The first circular plate 21 can drive the first clamping plate 31 and the second clamping plate 32 to move accordingly through the long rod 23. When the first clamping plates 31 and the second clamping plates 32 on both sides move towards each other, the fittings to be processed can be clamped.

[0026] A changing component for driving the second clamping plate 32 to rotate to different angles is provided on the first clamping plate 31.

[0027] By providing the changing component, the second clamping plate 32 can be driven to rotate to different angles. When the second clamping plate 32 and the first clamping plate 31 are in a vertical state, the cylindrical fittings can be clamped and positioned. Not only can the central axis of the fittings be on the same straight line as the central axis of the rectangular housing 1, but also the center position of the fittings can be locked to be on the same horizontal line as the center position of the first circular plate 21, as Figure 1 shown.

[0028] When cylindrical fittings or other shaped fittings do not need to lock the center position to be on the same horizontal line as the center of the first circular plate 21, the second clamping plate 32 can be rotated into the movable groove on the surface of the first clamping plate 31 to make the second clamping plate 32 and the first clamping plate 31 overlap, as Figure 4 shown.

[0029] When the second clamping plate 32 and the first clamping plate 31 are in an obtuse angle state, as Figure 5 shown, the four first clamping plates 31 and the second clamping plates 32 on the same horizontal plane can clamp and fix the circular sheet-shaped fittings, making the circular sheet-shaped fittings parallel to the ground, as Figure 12 shown; while the other four first clamping plates 31 and the second clamping plates 32 can also clamp and fix the circular sheet-shaped fittings, making the circular sheet-shaped fittings perpendicular to the ground, as Figure 11 shown; An adjusting mechanism for driving the first clamping plate 31 and the second clamping plate 32 to move along the straight groove 22 is provided inside the rectangular housing 1.

[0030] By providing the adjusting mechanism, the first clamping plate 31 and the second clamping plate 32 can be driven to move towards the center position of the first circular plate 21 or away from the center position of the first circular plate 21.

[0031] As Figure 2As shown in the figure, the two-way centering mechanism includes two threaded rods 41 that are rotatably connected and coaxially fixed inside the rectangular housing 1. The two threaded rods 41 are symmetrically distributed and have opposite thread directions on their surfaces. Inner threaded sleeves 42 that are threadedly connected to the threaded rods 41 are sleeved on both threaded rods 41. Limiting grooves 43 that are parallel to the threaded rods 41 are provided on the surface of the rectangular housing 1. L-shaped rods 44 that extend to the outside of the rectangular housing 1 through the limiting grooves 43 are fixedly connected to the surfaces of the two inner threaded sleeves 42. A U-shaped seat 45 is fixedly connected to the end of the L-shaped rod 44 away from the inner threaded sleeve 42. Two first circular plates 21 are respectively fixed on the two U-shaped seats 45.

[0032] Among them, the threaded rod 41 is driven by an external motor.

[0033] As Figure 6 and Figure 7 shown in the figure, the adjusting mechanism includes a second circular plate 51 that is rotatably connected to the first circular plate 21, and a worm gear 53 that is coaxially fixed to the second circular plate 51. An arc-shaped groove 52 that is adapted to the long rod 23 is provided on the surface of the second circular plate 51. A first circular shaft 54 that penetrates through both side walls of the U-shaped seat 45 and is rotatably connected to the U-shaped seat 45 is provided. A worm 55 that meshes with the worm gear 53 is sleeved on the first circular shaft 54.

[0034] Among them, when the second circular plate 51 and the arc-shaped groove 52 rotate, the side wall of the arc-shaped groove 52 can push the long rod 23 to slide along the linear groove 22, so that the long rod 23, the first clamping plate 31, and the second clamping plate 32 move towards the position close to the center of the first circular plate 21, or move away from the position close to the center of the first circular plate 21.

[0035] By setting the worm 55 and the worm gear 53, a self-locking function can be achieved for the second circular plate 51.

[0036] As Figure 8 shown in the figure, two symmetrically distributed rectangular frames 56 are provided inside the rectangular housing 1. Outer spline shafts 57 that penetrate through and are rotatably connected to the two opposite side walls of the rectangular frame 56 are provided. A first bevel gear 58 that is fixedly connected to the outer spline shaft 57 and is located inside the rectangular frame 56 is sleeved on the outer spline shaft 57. An inner spline shaft 511 that is rotatably connected inside the rectangular housing 1 and is parallel to the threaded rod 41 is provided. The inner spline shaft 511 passes through the outer spline shaft 57 and is adapted to the outer spline shaft 57.

[0037] Among them, the inner spline shaft 511 is driven by an external motor.

[0038] As Figure 8As shown in the figure, a rectangular groove 59 parallel to the internal spline shaft 511 is provided on the surface of the rectangular housing 1. Both of the first circular shafts 54 extend into the rectangular housing 1 through the rectangular groove 59, and penetrate through the side walls of the two rectangular frames 56 and then extend into the rectangular frames 56. The first circular shaft 54 is rotatably connected to the rectangular frame 56. A second bevel gear 510 fixedly connected thereto is sleeved on one end of the first circular shaft 54 located inside the rectangular frame 56. The second bevel gear 510 meshes with the first bevel gear 58.

[0039] With the above solution, when the internal spline shaft 511 rotates, it can drive the external spline shaft 57 to rotate accordingly. The external spline shaft 57 can drive the first bevel gear 58 sleeved on its surface to rotate accordingly. The first bevel gear 58 can drive the second bevel gear 510 meshing with it to rotate accordingly. The second bevel gear 510 can drive the first circular shaft 54 to rotate accordingly. The first circular shaft 54 can drive the worm 55 to rotate accordingly. The worm 55 can drive the worm gear 53 meshing with it to rotate accordingly. The worm gear 53 can drive the second circular plate 51 coaxially fixed thereto to rotate accordingly. In this way, it can be ensured that the two second circular plates 51 rotate simultaneously and have the same rotation angle. When the first circular shaft 54 slides along the rectangular groove 59, the first circular shaft 54 can drive the rectangular frame 56 and the external spline shaft 57 to slide along the internal spline shaft 511. As Figure 10 shown in the figure, the changing component includes a second circular shaft 61 penetrating through the first clamping plate 31 and rotatably connected to the first clamping plate 31. The second clamping plate 32 is sleeved on the second circular shaft 61 and fixedly connected to the second circular shaft 61. An annular sleeve 62 fixedly connected thereto is sleeved on one end of the second circular shaft 61. Two symmetrically distributed rectangular seats 63 are fixedly connected to the surface of the annular sleeve 62. Spring rods 64 are fixedly connected to both of the rectangular seats 63. A ratchet tooth 65 is fixedly connected to the free end of the spring rod 64.

[0040] As Figure 9 and Figure 10 shown in the figure, a hollow shaft 66 is rotatably connected to the side wall of the first clamping plate 31. A ratchet wheel 67 is fixedly connected to the inner wall of the hollow shaft 66. The ratchet wheel 67 meshes with the two ratchet teeth 65. A gear 68 fixedly connected thereto is sleeved on the surface of the hollow shaft 66. A bending rod 69 is fixedly connected to the side wall of the first circular plate 21. A rack 610 is fixedly connected to the free end of the bending rod 69.

[0041] The working principle of the present invention: The external motor drives the two coaxially fixed threaded rods 41 to rotate. The threaded rods 41 can drive the internal threaded sleeves 42 to move horizontally. Since the thread directions on the surfaces of the two threaded rods 41 are opposite, the two internal threaded sleeves 42 will move towards each other or move away from each other. The internal thread sleeve 42 can drive the first circular plate 21, the long rod 23, the first clamping plate 31, the second clamping plate 32 and the second circular plate 51 to move accordingly through the L-shaped rod 44 and the U-shaped seat 45; When the first clamping plates 31 on both sides of the rectangular housing 1 on both sides move towards each other, the fittings can be clamped and fixed; When the position of the first clamping plate 31 needs to be adjusted, when the internal spline shaft 511 is driven by the motor to rotate, it can drive the external spline shaft 57 to rotate accordingly. The external spline shaft 57 can drive the first bevel gear 58 sleeved on its surface to rotate accordingly. The first bevel gear 58 can drive the second bevel gear 510 meshing with it to rotate accordingly. The second bevel gear 510 can drive the first circular shaft 54 to rotate accordingly. The first circular shaft 54 can drive the worm 55 to rotate accordingly. The worm 55 can drive the worm gear 53 meshing with it to rotate accordingly. The worm gear 53 can drive the second circular plate 51 fixed coaxially with it to rotate accordingly. In this way, it can be ensured that the two second circular plates 51 rotate simultaneously and have the same rotation angle; When the second circular plate 51 and the arc-shaped groove 52 rotate, the side wall of the arc-shaped groove 52 can push the long rod 23 to slide along the linear groove 22, so that the long rod 23, the first clamping plate 31 and the second clamping plate 32 move towards the position close to the center of the first circular plate 21 or move away from the position close to the center of the first circular plate 21; When the angle of the second clamping plate 32 needs to be adjusted, drive the first clamping plate 31 and the second clamping plate 32 to move along the linear groove 22 towards the side close to the bending rod 69, so that the gear 68 and the rack 610 are in a meshing state. Then, when the gear 68 follows the first clamping plate 31 to reciprocate along the linear groove 22, a reciprocating rotation will be generated. The gear 68 can drive the ratchet wheel 67 to rotate reciprocally through the hollow shaft 66. The ratchet wheel 67 can drive the spring rod 64, the rectangular seat 63, the annular sleeve 62, the second circular shaft 61 and the second clamping plate 32 to rotate intermittently in the clockwise direction as shown in Figure 10 to change the working angle of the second clamping plate 32; Among them, the second clamping plate 32 can rotate a complete circle.

[0042] When the second clamping plate 32 and the first clamping plate 31 are in a vertical state, the cylindrical fittings can be clamped and positioned. It can not only make the central axis of the fittings and the central axis of the rectangular housing 1 on the same straight line, but also lock the center position of the fittings to be on the same horizontal line as the center position of the first circular plate 21, as shown in Figure 1 shown.

[0043] When a cylindrical fitting or a fitting of other shapes does not require locking the center position to be on the same horizontal line as the center of the first circular plate 21, the second clamping plate 32 can be rotated into the movable groove on the surface of the first clamping plate 31 to make the second clamping plate 32 and the first clamping plate 31 overlap, as Figure 4 shown.

[0044] When the second clamping plate 32 and the first clamping plate 31 are in an obtuse angle state, as Figure 5 shown, the four first clamping plates 31 and the second clamping plates 32 on the same horizontal plane can clamp and fix the disc-shaped fitting, making the disc-shaped fitting parallel to the ground; while the other four first clamping plates 31 and the second clamping plates 32 can also clamp and fix the disc-shaped fitting, making the disc-shaped fitting perpendicular to the ground.

[0045] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or elements inherent to such process, method, article or device.

[0046] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention.
