Description

Technical Field

[0001] This utility model relates to the field of glass rod processing technology, and in particular to an adjustable glass rod arc surface scribing device. Background Technology

[0002] Glass rods are solid materials made from glass, mostly with a circular cross-section. They possess strong chemical stability, high temperature resistance, smooth surface, and can be processed into rod-shaped forms of various shapes. They are widely used in laboratories, industrial manufacturing, and special scenarios. Using a scribing device to scribing their curved surfaces is crucial for providing a precise benchmark for subsequent processing and use. This not only clarifies the location of the shaping process to avoid morphological deviations but also provides a reference for functional positioning to ensure performance.

[0003] However, in existing technologies, glass rod arc surface scribing devices only clamp and position the glass rod at one end, while the other end is completely free and cantilevered, lacking effective support and constraint. This fixing method firstly causes the glass rod to bend, deform, sway radially, or even move axially during the scribing process due to the pressure and friction of the scribing components. This is especially true for glass rods with a large length-to-diameter ratio, where the stability of the cantilevered end is even worse, and "fluttering" is likely to occur. Secondly, single-end fixing makes it difficult to ensure that the axis of the glass rod is precisely parallel or coaxial with the guide rail trajectory of the scribing device, resulting in unstable contact between the arc surface and the scribing components, making it impossible to form uniform contact. This leads to a significant decrease in scribing accuracy, and the lines are prone to bending, discontinuity, and positional deviation. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art by proposing an adjustable glass rod arc surface scribing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: It includes a base, the upper part of which is fixedly connected to an adjustment mechanism, a guide mechanism, and a marking mechanism. The upper part of the adjustment mechanism is fixedly connected to two clamping mechanisms. The adjustment mechanism includes a first servo motor, the output end of which is fixedly connected to a first lead screw. The surface of the first lead screw has two threads in opposite directions, and the surfaces of the two threads in opposite directions are respectively threaded with first thread blocks. The clamping mechanism includes a first fixing plate, which is installed on the upper part of the guide mechanism. An annular slide rail is fixedly connected to the upper part of the first fixing plate. An annular slider is slidably connected inside the annular slide rail. A mounting bracket is fixedly connected to the inner side of the annular slider, and a clamp is fixedly connected to the side of the mounting bracket.

[0006] Preferably, a second servo motor is fixedly connected to the upper part of the first fixing plate, and the output end of the second servo motor is fixedly connected to the surface of the mounting bracket.

[0007] Preferably, the guiding mechanism includes a strip slide rail, with a first strip slider slidably connected to the upper part of the strip slide rail, and the first strip slider being fixedly connected to the bottom of a first fixing plate.

[0008] Preferably, the marking mechanism includes a No. 3 servo motor, the output end of which is fixedly connected to a No. 2 lead screw, a No. 2 lead block is threaded onto the surface of the No. 2 lead screw, a No. 2 fixing plate is fixedly connected to the upper part of the No. 2 lead block, a mounting plate is fixedly connected to the upper part of the No. 2 fixing plate, an electric telescopic cylinder is mounted on the side of the mounting plate, and a cutter head is mounted on the end of the electric telescopic cylinder.

[0009] Preferably, the guiding mechanism further includes a second strip slider, which is slidably connected to the upper part of the strip rail and slidably connected to the bottom of the second fixing plate.

[0010] Preferably, lead screw No. 1 is rotatably connected to the upper part of the base, and lead screw No. 2 is rotatably connected to the upper part of the base.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] 1. In this utility model, the No. 1 servo motor in the adjustment mechanism drives the No. 1 lead screw with reverse thread to rotate, which can drive the two No. 1 lead blocks to move closer synchronously, thereby enabling the two clamping mechanisms to clamp the two ends of the glass rod respectively. This replaces the single-end fixing and avoids the bending deformation, radial swaying and axial movement of the glass rod caused by the cantilever. In particular, it improves the stability of glass rods with a large length-to-diameter ratio. The strip slide rail of the guide mechanism cooperates with the No. 1 strip slider to limit and guide the movement of the No. 1 fixing plate, ensuring the coaxiality of the two clamping mechanisms when they move and avoiding the deviation of the glass rod axis from the scribing trajectory. It can also provide support for the clamping mechanism during the scribing process, further improving the fit stability between the arc surface and the scribing mechanism. Ultimately, it significantly improves the scribing accuracy and reduces problems such as line bending, discontinuity and deviation.

[0013] 2. In this utility model, the accuracy, controllability, and stability of arc surface scribing are effectively improved through the coordinated cooperation of the scribing mechanism and related components of the guiding mechanism. In the scribing mechanism, the No. 3 servo motor drives the No. 2 lead screw to rotate precisely, which drives the No. 2 lead block and the No. 2 fixing plate to move stably, thereby achieving precise adjustment of the horizontal position of the mounting plate, electric telescopic cylinder, and cutter head, ensuring that the cutter head can be aligned with the target position of the glass rod to be scribed. The electric telescopic cylinder can be flexibly extended and retracted to control the degree of contact between the cutter head and the glass rod, which facilitates precise control of the scribing force and avoids glass breakage or scribing marks that are too shallow or intermittent due to improper force.

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0021] Example 1: As Figure 1 - Figure 4As shown, this utility model provides an adjustable glass rod arc surface scribing device, including a base 1. An adjustment mechanism 2, a guide mechanism 4, and a scribing mechanism 5 are fixedly connected to the upper part of the base 1. Two clamping mechanisms 3 are fixedly connected to the upper part of the adjustment mechanism 2. The adjustment mechanism 2 includes a first servo motor 21, and a first lead screw 22 is fixedly connected to the output end of the first servo motor 21. The surface of the first lead screw 22 is provided with two threads in opposite directions, and first thread blocks 23 are threadedly connected to the surfaces of the two threads in opposite directions. The clamping mechanism 3 includes a first fixing plate 36, which is installed on the upper part of the guide mechanism 4. An annular slide rail 31 is fixedly connected to the upper part, and an annular slider 32 is slidably connected inside the annular slide rail 31. A mounting bracket 33 is fixedly connected to the inner side of the annular slider 32, and a clamp 34 is fixedly connected to the side of the mounting bracket 33. A second servo motor 35 is fixedly connected to the upper part of the first fixing plate 36, and the output end of the second servo motor 35 is fixedly connected to the surface of the mounting bracket 33. The guide mechanism 4 includes a strip slide rail 41, and a first strip slider 42 is slidably connected to the upper part of the strip slide rail 41. The first strip slider 42 is fixedly connected to the bottom of the first fixing plate 36. A first lead screw 22 is rotatably connected to the upper part of the base 1, and a second lead screw 52 is rotatably connected to the upper part of the base 1.

[0022] The specific settings and functions of this embodiment are described below: The first servo motor 21 in the adjusting mechanism 2 drives the first lead screw 22 with a reverse thread to rotate, which in turn drives the two first lead blocks 23 to move closer synchronously. This allows the two clamping mechanisms 3 to clamp both ends of the glass rod, replacing single-end fixing and avoiding bending deformation, radial swaying, and axial movement of the glass rod caused by cantilever, especially improving the stability of glass rods with a large length-to-diameter ratio. In the clamping mechanism 3, the second servo motor 35 drives the safety mechanism 32, which is slidably connected to the annular slider 32 along the annular slide rail 31. The rotation of the mounting bracket 33 allows the glass rod fixed by the clamp 34 to flexibly adjust its angle to adapt to the scribing requirements of different curved surfaces. The strip slide rail 41 of the guide mechanism 4 cooperates with the first strip slider 42 to limit and guide the movement of the first fixing plate 36, ensuring the coaxiality of the two clamping mechanisms 3 when they move, and preventing the glass rod axis from deviating from the scribing trajectory. It also provides support for the clamping mechanism 3 during the scribing process, further improving the fit stability between the curved surface and the scribing mechanism 5, and ultimately significantly improving the scribing accuracy and reducing problems such as line bending, discontinuity, and deviation.

[0023] Example 2: Figure 1 - Figure 4As shown, the marking mechanism 5 includes a third servo motor 51, the output end of which is fixedly connected to a second lead screw 52, ​​the surface of which is threaded with a second lead block 53, the upper part of which is fixedly connected to a second fixing plate 54, the upper part of which is fixedly connected to a mounting plate 55, the side of which is mounted with an electric telescopic cylinder 56, and the end of which is mounted with a cutter head 57. The guide mechanism 4 also includes a second strip slider 43, which is slidably connected to the upper part of a strip rail 41 and slidably connected to the bottom of the second fixing plate 54.

[0024] The overall effect of this embodiment is that, through the coordinated operation of the scribing mechanism 5 and the related components of the guiding mechanism 4, the accuracy, controllability, and stability of the arc surface scribing are effectively improved. In the scribing mechanism 5, the third servo motor 51 drives the second lead screw 52 to rotate precisely, which in turn drives the second lead block 53 and the second fixing plate 54 to move stably, thereby achieving precise adjustment of the horizontal position of the mounting plate 55, the electric telescopic cylinder 56, and the cutter head 57, ensuring that the cutter head 57 can be aligned with the target position of the glass rod to be scribed. The electric telescopic cylinder 56 can be flexibly extended and retracted to control the degree of contact between the cutter head 57 and the glass rod, which facilitates precise control of the scribing force and avoids glass breakage or shallow or intermittent scribing marks due to improper force. The second strip slider 43 of the guiding mechanism 4 slides along the strip slide rail 41, which plays a reliable limiting and guiding role in the movement of the second fixing plate 54, preventing it from deviating during horizontal movement, and further ensuring the stability of the movement trajectory of the cutter head 57, ultimately achieving accurate, stable, and force-controllable arc surface scribing operation.

[0025] The usage and working principle of this device are as follows: First, one end of the glass rod is clamped and fixed with the clamp 34 in a clamping mechanism 3. Then, the first servo motor 21 drives the first lead screw 22 to rotate, causing the two first lead blocks 23 to move closer to each other, thereby driving the two clamping mechanisms 3 to move closer to each other, and then causing the other clamp 34 to clamp and fix the other end of the glass rod, ensuring the stability of the glass rod when scribing. When the first lead block 23 drives the two first fixing plates 36 to move, the first strip slider 42 slides along the strip slide rail 41 to limit the movement of the first fixing plate 36, and at the same time, it limits the clamping mechanism 3 during the scribing process, improving the stability during scribing.

[0026] The No. 3 servo motor 51 drives the No. 2 lead screw 52 to rotate, thereby moving the No. 2 lead block 53 and the No. 2 fixing plate 54. The movement of the No. 2 fixing plate 54 adjusts the horizontal position of the cutting head 57 installed on the mounting plate 55 and the end of the electric telescopic cylinder 56, so that it can accurately perform the scribing operation on the glass rod. The extension and retraction of the electric telescopic cylinder 56 controls the contact between the cutting head 57 and the glass rod, which facilitates the control of the scribing force. When the No. 2 fixing plate 54 moves horizontally, the No. 2 strip slider 43 slides along the strip slide rail 41, thereby limiting the movement of the No. 2 fixing plate 54 and improving the stability of the scribing mechanism 5 during movement and scribing.

[0027] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
