Description

Technical Field

[0001] The utility model relates to the technical field of glass machinery, and particularly relates to a coaxiality detection device for a edge roller. Background Art

[0002] The edge roller is one of the key devices in the production of float glass, playing an important role in throttling, thinning, thickening and controlling the running direction of the original plate. The edge roller at the front end of the edge roller machine pulls the glass ribbon floating on the tin bath liquid surface forward, and by adjusting the linear speed of the edge roller and the horizontal swing angle, plane inclination angle, etc. of the edge roller, the purpose of controlling the thickness of the glass ribbon and stabilizing the width of the glass ribbon is achieved.

[0003] Therefore, the edge roller is one of the key parts on the edge roller machine. The teeth on the edge of the edge roller play a role in pulling the glass ribbon. If the coaxiality between these teeth and the mounting holes of the edge roller is not good, the edge roller will vibrate up and down during rotation, and at the same time cause fluctuations in the tin liquid surface, directly affecting the flatness of the glass ribbon, etc. For a thin glass production line, the impact on the quality of the glass plate is even worse.

[0004] At present, there is no suitable detection means to control the coaxiality between the teeth of the edge roller and the mounting holes, resulting in the fact that the tooth runout exceeds the tolerance can only be found during the test run after the edge roller is installed. Content of the Utility Model

[0005] The utility model aims to solve at least one of the technical problems existing in the prior art. For this reason, the utility model provides a coaxiality detection device for an edge roller. When the mandrel rotates, the edge roller body is synchronously driven to rotate. Through the rotation of the edge roller teeth on the detection mechanism, the coaxiality of the edge roller body is detected, and the detection efficiency and accuracy are improved.

[0006] To achieve the above object, according to an embodiment of the first aspect of the utility model, a coaxiality detection device for an edge roller is provided, which includes a detection platform, a mounting mechanism, a positioning mechanism and a detection mechanism. The detection platform is L-shaped. The mounting mechanism is arranged on the top of the detection platform, and the detection mechanism is arranged on the side wall of the detection platform. The mounting mechanism includes a bearing seat, a bearing, a mandrel and an edge roller body. The bearing seat is fixedly arranged on the top of the detection platform. The mandrel is rotatably arranged on the bearing seat through the bearing. The positioning mechanism positions the installation position of the mandrel. The front end of the mandrel is connected to the edge roller body. A thread is arranged at the front end of the mandrel, and a positioning journal is arranged at the end of the thread. A thread groove is arranged in the edge roller body, and a positioning hole is arranged on one side of the thread groove. The positioning journal is arranged at the positioning hole, and the thread is matched with the thread groove. Edge roller teeth are arranged on the outer side wall of the edge roller body. The detection mechanism is connected to the edge roller teeth to detect the coaxiality of the edge roller.

[0007] As a further solution of the utility model: the positioning mechanism includes a gland, a snap ring and an expansion sleeve. The gland is arranged on one side wall of the bearing seat to limit the front end of the mandrel. The snap ring is arranged on the other side wall of the bearing seat to elastically support the rear end of the mandrel. The expansion sleeve positions the snap ring.

[0008] As a further solution of the utility model: the detection mechanism includes a dial indicator and a flat detection head. The bottom of the flat detection head is connected to the dial indicator, and the flat detection head is arranged between the teeth of the edge pulling wheel.

[0009] As a further solution of the utility model: the dial indicator is fixedly arranged on the lifting platform, and the lifting platform is slidably arranged on the side wall of the detection platform.

[0010] As a further solution of the utility model: a flat tail is arranged on the side where the rear end of the mandrel extends out of the bearing seat.

[0011] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0012] 1. The utility model installs the edge pulling wheel body through the connection of the thread and the thread groove. At the same time, the positioning journal is inserted into the positioning hole to achieve double positioning, improving the stability and coaxiality of the connection of the edge pulling wheel body. The detection mechanism is connected to the teeth of the edge pulling wheel. When the mandrel rotates, it synchronously drives the edge pulling wheel body to rotate. By the rotation of the teeth of the edge pulling wheel on the detection mechanism, the coaxiality of the edge pulling wheel body is detected.

[0013] 2. The utility model, through the limitation of the front end of the mandrel by the gland, the elastic support of the rear end of the mandrel by the snap ring, and the stable positioning of the snap ring by the expansion sleeve, jointly constitutes a high-precision positioning mechanism, which can effectively reduce the axial offset and vibration of the mandrel during rotation, thereby improving the accuracy of the coaxiality detection of the edge pulling wheel.

[0014] 3. The utility model presses the flat detection head against the teeth of the edge pulling wheel. When the edge pulling wheel body rotates, the flat detection head measures parameters such as the radial runout and axial offset of the teeth of the edge pulling wheel, and reflects the coaxiality of the edge pulling wheel body through the parameter change of the dial indicator.

[0015] 4. The utility model is slidably arranged on the side wall of the detection platform through the lifting platform, and can adapt to edge pulling wheel bodies of different sizes and installation heights. This flexibility makes the detection device more versatile, can meet a variety of different detection requirements, and has a wider application range.

[0016] 5. The utility model is provided with a flat tail, which is convenient for fixing the mandrel when installing the edge pulling wheel body, preventing the mandrel from rotating, and improving the installation efficiency. Description of the Drawings

Specific embodiments

[0022] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all 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 4 shown, a coaxiality detection device for a pulling wheel includes a detection platform 1, an installation mechanism, a positioning mechanism and a detection mechanism. The detection platform 1 is L-shaped. The installation mechanism is arranged on the top of the detection platform 1, and the detection mechanism is arranged on the side wall of the detection platform 1. The installation mechanism includes a bearing seat 2, a bearing 21 and a mandrel 3. The bearing seat 2 is fixedly arranged on the top of the detection platform 1, and the mandrel 3 is rotatably arranged on the bearing seat 2 through the bearing 21. The positioning mechanism positions the installation position of the mandrel 3 to improve the rotation stability of the mandrel 3.

[0024] The front end of the mandrel 3 is connected to the pulling wheel body 4. A thread 31 is arranged at the front end of the mandrel 3, and a positioning journal 32 is arranged behind the thread 31. A thread groove 41 is arranged inside the pulling wheel body 4, and a positioning hole 42 is arranged on one side of the thread groove 41. The positioning journal 32 is arranged at the positioning hole 42. The thread 31 is threadedly connected to the thread groove 41. Pulling wheel teeth 43 are arranged on the outer side wall of the pulling wheel body 4. The detection mechanism is connected to the pulling wheel teeth 43 to detect the coaxiality of the pulling wheel.

[0025] The pulling wheel body 4 is installed by connecting the thread 31 and the thread groove 41. At the same time, the positioning journal 32 is inserted into the positioning hole 42 to achieve double positioning, improving the stability and coaxiality of the connection of the pulling wheel body 4. The detection mechanism is connected to the pulling wheel teeth 43. When the rotating mandrel 3 rotates, the pulling wheel body 4 is driven to rotate synchronously. The coaxiality of the pulling wheel body 4 is detected by the rotation of the pulling wheel teeth 43 on the detection mechanism.

[0026] The positioning mechanism includes a gland 22, a snap ring 23 and an expansion sleeve 24. The gland 22 is arranged on one side wall of the bearing seat 2 to limit the front end of the mandrel 3. The snap ring 23 is arranged on the other side wall of the bearing seat 2 to elastically support the rear end of the mandrel 3. The expansion sleeve 24 positions the snap ring 23.

[0027] The limit of the front end of the mandrel 3 by the gland 22, the elastic support of the rear end of the mandrel 3 by the snap ring 23, and the stable positioning of the snap ring 23 by the expansion sleeve 24 together constitute a high-precision positioning mechanism, which can effectively reduce the axial offset and vibration of the mandrel 3 during rotation, thereby improving the accuracy of the coaxiality detection of the pulling wheel.

[0028] The detection mechanism includes a dial indicator 5 and a flat detection head 51. The bottom of the flat detection head 51 is connected to the dial indicator 5, and the flat detection head 51 is arranged between the pulling wheel teeth 43.

[0029] When the flat detection head 51 is pressed against the pulling wheel teeth 43 and the pulling wheel body 4 rotates, the flat detection head 51 measures parameters such as the radial runout and axial offset of the pulling wheel teeth 43, and the coaxiality of the pulling wheel body 4 is reflected by the parameter change of the dial indicator 5.

[0030] The dial indicator 5 is fixedly arranged on the lifting table 6, and the lifting table 6 is slidably arranged on the side wall of the detection platform 1.

[0031] By slidably arranging the lifting table 6 on the side wall of the detection platform 1, it can adapt to the pulling wheel body 4 with different sizes and installation heights. This flexibility makes the detection device more versatile, capable of meeting various different detection requirements, and having a wider application range.

[0032] A flat tail 33 is arranged on the side where the rear end of the mandrel 3 extends out of the bearing seat 2.

[0033] By providing the flat tail 33, it is convenient to fix the mandrel 3 when installing the pulling wheel body 4, prevent the mandrel 3 from rotating, and improve the installation efficiency.

[0034] Working principle of the utility model: The draw-roller body 4 is installed on the mandrel 3 through the connection and cooperation of the thread 31 and the thread groove 41. At the same time, the positioning journal 32 of the mandrel 3 and the positioning hole 42 of the draw-roller body 4 are precisely matched. Place the dial indicator 5 on the lifting table 6, adjust the height of the lifting table 6 so that the plane detection head 51 of the dial indicator 5 presses tightly against the draw-roller tooth 43. Manually rotate the rear part of the mandrel 3 to drive the draw-roller body 4 to rotate. At this time, the runout of the draw-roller tooth 43 can be measured through the dynamic display of the dial indicator 5, indirectly reflecting the coaxiality between the draw-roller tooth 43 and the positioning hole 42 on the draw-roller body 4.

[0035] The above embodiments are only used to illustrate the technical method of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical method of the utility model can be modified or equivalently replaced without departing from the spirit and scope of the technical method of the utility model.
