Description

Technical Field

[0001] This utility model relates to the field of detection device technology, and in particular to a detection device for the relative positional accuracy of the swing shaft and the main shaft of an upper swing machine. Background Technology

[0002] An upper swing machine is a piece of equipment used in the production of optical lenses. Its characteristic is that it can achieve precise processing of optical lenses through specific mechanical structures and operating methods.

[0003] Reference to the utility model patent with authorization announcement number CN218097589U discloses a detection device for the relative position accuracy of the swing shaft and the main shaft of an upper swing machine. This detection device for the relative position accuracy of the swing shaft and the main shaft of an upper swing machine has a first moving device that moves along the length direction of the base plate on the first upright plate, a second moving device that moves along the width direction of the base plate on the movable end of the first moving device, a third moving device that moves along the height direction of the base plate on the movable end of the second moving device, a detection seat on the movable end of the third moving device, and a laser irradiation device that can emit lasers vertically toward the floor and the first upright plate on the detection seat.

[0004] The aforementioned patent uses a laser irradiation instrument for irradiation detection, but it cannot accurately locate the axis of the upper pendulum machine's pendulum shaft and the main shaft during the detection process, so its detection accuracy is difficult to guarantee. To solve the drawbacks of the above technology, we propose a detection device for the relative position accuracy of the upper pendulum machine's pendulum shaft and the main shaft. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a device for detecting the relative positional accuracy of the pendulum shaft and the main shaft of an upper pendulum machine.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A device for detecting the relative positional accuracy of the upper pendulum shaft and the main shaft of a pendulum machine includes two sleeves for fitting the upper pendulum shaft and the main shaft. Each sleeve is equipped with a positioning and locking assembly and a measuring assembly. The positioning and locking assembly includes an internally threaded cylinder with a protruding thread on its outer side. The internally threaded cylinder is screwed onto the outer side of the protruding thread. A tapered cylinder is fixedly connected to the side of the internally threaded cylinder. A sliding hole is provided on the sleeve, and a sliding rod is slidably installed inside the sliding hole. A spring is connected between the outer wall of the sliding rod and the outer wall of the sleeve. An inner abutment cylinder is slidably inserted inside the sleeve.

[0008] Furthermore, a positioning hole is provided on the inner abutment cylinder, and the inner force of the positioning hole is equal to that of the sliding hole.

[0009] By adopting the above technical solution, the inner force of the positioning hole is equal to that of the sliding hole, so that the inner end of the sliding rod can be inserted into the inner side of the positioning hole of the inner abutment cylinder, so that the inner abutment cylinder can be fixed on the inner wall of the sleeve. At the same time, this setting allows for the replacement of inner abutment cylinders with different inner diameters, so that the inside of the inner abutment cylinder can fit snugly on the outside of the upper swing shaft and the main shaft, giving this utility model the ability to detect the position of the upper swing shaft and the main shaft with different diameters, thus expanding the scope of application.

[0010] Furthermore, the spring is a durable tension spring.

[0011] Furthermore, an outer arc seat is fixedly installed on the outer end of the second slide rod, and an inner arc seat is fixedly installed on the inner end of the second slide rod. The inner arc seat is made of high-damping rubber.

[0012] By adopting the above technical solution, the inner arc seat is made of high-damping rubber material. When the inner arc seat at the inner end of the second drive slide rod abuts against the outer side of the upper swing shaft and the main shaft, the high friction limiting ability of the high-damping rubber material can be used to position the inner abutting cylinder on the outer side of the upper swing shaft and the main shaft.

[0013] Furthermore, an auxiliary rod is fixedly installed on the internal threaded cylinder.

[0014] Furthermore, a sleeve rod is provided on the left sleeve, and a sliding rod is provided on the right sleeve. The sleeve rod is slidably sleeved on the outside of the sliding rod. Both the sleeve rod and the sliding rod are provided with length scale marks.

[0015] By adopting the above technical solution, the sum of the scale marks on the sleeve rod and the scale marks at the intersection of the slide rod and the sleeve rod is the distance between the centers of the two sleeves. Since the sleeve is fitted on the outside of the upper swing machine's swing shaft and main shaft through the inner abutment cylinder, this distance is the distance between the center positions of the upper swing machine's swing shaft and main shaft.

[0016] Furthermore, the measuring component includes a support column, which is fixedly installed on the outer wall of the sleeve. An installation plate is rotatably installed on the upper side of the support column, and a turntable is rotatably installed on the upper side of the installation plate. A folding rod is fixedly installed on the turntable.

[0017] Furthermore, a stud is fixedly installed at the end of the folding rod, and the stud is screwed to the sleeve rod or slide rod.

[0018] By adopting the above technical solution, different length sleeves or slides can be screwed onto the stud to achieve measurement work with different distance requirements.

[0019] Furthermore, the mounting plate has equidistant angle scales on its upper circumference, and a pointer is fixedly installed on the lower side of the folding rod.

[0020] Furthermore, the center lines of the support column, mounting plate, and turntable coincide, and the center lines of the support column, mounting plate, and turntable pass through the center of the sleeve.

[0021] By adopting the above technical solution, the center lines of the support column, mounting plate, and turntable pass through the center of the sleeve, ensuring that the position of the rotating rod at one end of the sleeve or slide rod corresponds to the center of the upper swing machine's swing axis and the main shaft. Then, the sum of the corresponding length scales on the slide rod and the sleeve rod during installation is the specific distance between the center of the upper swing machine's swing axis and the main shaft.

[0022] Compared with related technologies, the detection device for the relative positional accuracy of the pendulum shaft and the main shaft of the upper pendulum machine proposed in this utility model has the following beneficial effects:

[0023] In this invention, a device for detecting the relative positional accuracy of the upper pendulum shaft and the main shaft of a pendulum machine is described. Through a positioning and locking component, two sleeves are respectively fitted onto the outside of the upper pendulum shaft and the main shaft during testing. At this time, the center lines of the support column, mounting plate, and turntable pass through the center of the sleeve. Consequently, the position of the rotating point of the sliding rod or the end of the sleeve corresponds to the center of the upper pendulum shaft and the main shaft. The sum of the corresponding length scales on the sliding rod and the sleeve is the distance between the center positions of the pendulum shaft and the column shaft. The measuring component of this invention uses the positioning and locking component to accurately position itself, thereby ensuring the accuracy of the test results.

[0024] In addition, the positioning and locking assembly can be fitted with inner abutment cylinders of different inner diameters, so that the inside of the inner abutment cylinder can fit snugly on the outside of the upper swing shaft and the main shaft, giving this utility model the ability to detect the position of the upper swing shaft and the main shaft of different diameters, thus expanding its scope of application.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0033] Reference Figure 1-6 A device for detecting the relative positional accuracy of the upper swing shaft and the main shaft of a swing machine includes two sleeves 1 for fitting the upper swing shaft and the main shaft. The sleeves 1 are provided with a positioning and locking component 5 and a measuring component 6. The positioning and locking component 5 includes an internal threaded cylinder 51. The outer side of the sleeve 1 is provided with a protruding thread 53. The internal threaded cylinder 51 is screwed to the outer side of the protruding thread 53. A tapered cylinder 52 is fixedly connected to the side of the internal threaded cylinder 51. A sliding hole 54 is opened on the sleeve 1. A sliding rod 55 is slidably installed inside the sliding hole 54. A spring 56 is connected between the outer wall of the sliding rod 55 and the outer wall of the sleeve 1. An inner abutment cylinder 59 is slidably inserted inside the sleeve 1.

[0034] In this embodiment, a positioning hole 510 is provided on the inner abutment cylinder 59, and the inner force of the positioning hole 510 is equal to that of the sliding hole 54.

[0035] Through the above structure, the inner core of the positioning hole 510 and the sliding hole 54 are connected, and the internal threaded cylinder 51 is rotated. This causes the inner part of the lateral cone cylinder 52 to abut against the outer arc seat 57 at the outer end of the slide rod 55, which drives the slide rod 55 to slide inward. This allows the slide rod 55 to be inserted into the inner side of the sliding hole 54, thus fixing the inner abutting cylinder 59 inside the sleeve 1. Continuing to push the slide rod 55, the inner arc seat 58 at the inner end of the slide rod 55 abuts against the outer side of the upper swing shaft and the main shaft, thereby completing the positioning and fixing work on the outer side of the upper swing shaft and the main shaft. The slide rod 55 provided here not only has the function of fixing the inner abutting cylinder 59, but also has the function of positioning on the outer wall of the upper swing shaft and the main shaft during testing.

[0036] In this embodiment, spring 56 is a durable tension spring.

[0037] Through the above structure, spring 56 is a durable tension spring, which can provide the slide rod 55 with an outward pull force. When the internal threaded cylinder 51 is rotated to drive the tapered cylinder 52 to slide outward, the slide rod 55 will automatically slide outward under the pull force of spring 56. When the inner end of the slide rod 55 slides out of the positioning hole 510 of the inner abutment cylinder 59, the inner abutment cylinder 59 can be pulled out from the sleeve 1. This allows the device to replace the inner abutment cylinder 59 with different inner diameters, so that its inner side can fit and be sleeved on the outside of the swing shaft or main shaft of different diameters, thus improving the applicability.

[0038] In this embodiment, an outer arc seat 57 is fixedly installed on the outer end of the slide rod 55, and an inner arc seat 58 is fixedly installed on the inner end of the slide rod 55. The inner arc seat 58 is made of high-damping rubber.

[0039] Through the above structure, the inner arc seat 58 is made of high-damping rubber material, which improves the contact, limiting and sliding ability of the inner arc seat 58.

[0040] In this embodiment, an auxiliary rod 511 is fixedly installed on the internal threaded cylinder 51.

[0041] With the above structure, the auxiliary rod 511 is set up to facilitate the rotation of the internal threaded cylinder 51.

[0042] In this embodiment, a sleeve rod 2 is provided on the left sleeve 1, and a sliding rod 3 is provided on the right sleeve 1. The sleeve rod 2 is slidably sleeved on the outside of the sliding rod 3. Both the sleeve rod 2 and the sliding rod 3 are provided with length scale marks 4. The center lines of the support column 61, the mounting plate 62 and the turntable 64 coincide and the center lines of the support column 61, the mounting plate 62 and the turntable 64 pass through the center of the sleeve 1.

[0043] It should be noted that the length scale mark 4 represents the distance from the center of the turntable 64. The length of the folding rod 65 and the radius of the turntable 64 are taken into account. Since the folding rod 65 and the turntable 64 are fixed values, these fixed values ​​are constant in this testing device. The starting scale value of the slide rod 3 or the sleeve rod 2 has already taken this length value into account. Therefore, during the testing process, the scale value at the junction of the slide rod 3 and the sleeve rod 2 and the total length scale value on the sleeve rod 2 are added together to obtain the distance between the center points of the two turntables 64. Since the center lines of the support column 61, the mounting plate 62 and the turntable 64 pass through the center of the sleeve 1, this value is equal to the distance between the detection center points of the main shaft and the swing shaft.

[0044] In this embodiment, the measuring component 6 includes a support column 61, which is fixedly installed on the outer wall of the sleeve 1. A mounting plate 62 is rotatably installed on the upper side of the support column 61, and a turntable 64 is rotatably installed on the upper side of the mounting plate 62. A folding rod 65 is fixedly installed on the turntable 64, and a stud 66 is fixedly installed at the end of the folding rod 65. The stud 66 is screwed to the sleeve 2 or the slide rod 3. Angle scale marks 63 are equidistantly arranged on the upper circumference of the mounting plate 62, and a pointer 67 is fixedly installed on the lower side of the folding rod 65.

[0045] With the above structure, the angle scale mark 63 on the mounting plate 62 corresponding to pointer 67 is the angle between the line connecting slide rod 3 and sleeve rod 2 and the starting mark on turntable 64. The starting mark on turntable 64 is parallel to sleeve 1. Therefore, this angle is the angle between the line connecting slide rod 3 and sleeve rod 2 and the main shaft or swing shaft. The angle values ​​on both turntables 64 are recorded. Subsequently, using the principle that the sum of the interior angles of a triangle is a constant, the rotation angle value of the relative position between the upper swing shaft and the main shaft can be directly calculated. This setting enables the present invention to detect the relative rotation angle between the upper swing shaft and the main shaft.

[0046] In this invention, during use, two sleeves 1 are respectively fitted onto the outside of the swing shaft and main shaft of the upper swing machine to be tested. The inner abutment sleeve 59 is fitted onto the outside of the swing shaft and main shaft. Subsequently, the auxiliary rod 511 drives the internal threaded cylinder 51 to rotate, driving the cone cylinder 52 to slide inward. Under the abutment action of the inner side of the cone cylinder 52, the slide rod 2 55 is driven to slide inward, so that the inner arc seat 58 of the inner end of the slide rod 2 55 is stably abutted against the outside of the main shaft and the swing shaft. After fixing, the scale value at the junction of the slide rod 1 3 and the sleeve 2 is observed. The scale value at the junction of the slide rod 1 3 and the sleeve 2 and the total length scale value on the sleeve 2 are added together to obtain the distance between the detection center positions of the main shaft and the swing shaft. Subsequently, the angle scale indicated by the pointer 67 is observed and recorded. After the angles on both mounting plates 62 are recorded, the relative angle between the main shaft and the swing shaft can be directly calculated based on the fixed value that the sum of the inner angles is a straight angle.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects. The scope of this utility model is defined by the appended claims rather than the foregoing description, and thus all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0048] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
