Description

Technical Field

[0001] The utility model relates to the technical field of flatness measuring instruments, in particular to a flatness measuring instrument convenient for clamping. Background Technique

[0002] The glass curtain wall panel is the main part of the glass curtain wall, usually made of glass materials. The glass curtain wall is a beautiful and novel building wall. When the glass curtain wall panel is produced, a flatness measuring instrument is needed to measure the flatness of its surface, so as to prevent unqualified glass curtain wall panels from flowing into the market. There are still certain defects in the existing flatness measuring instruments when in use.

[0003] In the prior art, the flatness measuring instrument measures the flatness of the glass surface by irradiating the light on the glass surface through a laser measuring probe and reflecting it back. Since the glass surface is relatively smooth, when the glass is placed on the support block, it is easy to shift and slide in position due to the unstable placement and collision of the measuring frame body, thus affecting the efficiency of glass measurement. Content of the Utility Model

[0004] The purpose of the utility model is to provide a flatness measuring instrument convenient for clamping, so as to solve the problem that the glass on the existing flatness measuring instrument in the current market is easy to slide as put forward in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A flatness measuring instrument convenient for clamping, comprising: a measuring frame body, a display controller, a support block, a moving cross beam and a laser measuring probe. The outside of the measuring frame body is connected with a display controller. The surface of the measuring frame body is provided with a support block. The top of the measuring frame body is connected with a moving cross beam through a slide rail. The bottom of the moving cross beam is provided with a laser measuring probe. A motor is installed at the front of the measuring frame body. A connecting block is welded at the front of the measuring frame body close to the motor. A bidirectional lead screw is connected inside the connecting block through a bearing. A bevel gear set is sleeved between the outside of the bidirectional lead screw and the output end of the motor. A slider is threadedly connected to the outside of the bidirectional lead screw. A clamping plate is installed on the back of the slider. Rubber pads are bonded to the opposite sides of the two clamping plates. Wear-resistant cloth blocks are bonded to the surfaces of the rubber pads. A guide rod is welded inside the measuring frame body. A fixed seat is welded on the surface of the measuring frame body close to the support block. A telescopic spring is connected inside the fixed seat. One end of the telescopic spring is connected with a pressing block. A guide block is welded at the bottom of the pressing block.

[0006] Preferably, a sliding structure is formed between the clamping plate and the guide rod, and two groups of clamping plates are symmetrically arranged about the center of the measuring frame body.

[0007] Preferably, a semi-circular block is adhesively bonded to the top of the extrusion block, and the semi-circular block is made of rubber material.

[0008] Compared with the prior art, the beneficial effects of the present utility model are as follows: for this flatness measuring device that is convenient to clamp, when the motor rotates forward, it can drive the bevel gear set to engage and rotate. When the bevel gear set rotates, it can drive the bidirectional lead screw to rotate forward. When the bidirectional lead screw rotates forward, it can drive two groups of sliders to perform threaded sliding towards each other. The bottom of the glass can move to the top of the support block. At this time, the glass will not generate a large impact force. Through the semi-circular block and the telescopic spring, the glass can play a buffering effect during the placement process, thereby avoiding the glass directly colliding with the support block, reducing the impact force, and making the glass not easily broken.

[0009] 1. The flatness measuring device calculates the undulation of the glass surface by measuring the reflection angle of the light emitted by the laser measuring probe, so as to determine the flatness of the glass surface. However, the glass is placed on the support block relatively unstably. When the motor rotates forward, it can drive the bevel gear set to engage and rotate. When the bevel gear set rotates, it can drive the bidirectional lead screw to rotate forward. When the bidirectional lead screw rotates forward, it can drive two groups of sliders to perform threaded sliding towards each other. When the sliders perform threaded sliding, they can drive the clamping plates to move. When one side of the wear-resistant cloth block moves to the side surface of the glass, the two clamping plates can quickly clamp the glass, and the rubber pads and the wear-resistant cloth blocks can protect both sides of the glass, avoiding the clamping plates directly contacting both sides of the glass. Through the two clamping plates, the glass can be quickly clamped and limited, making the glass not easily slide and shift in position on the support block, and improving the stability of the flatness measuring device for placing the glass.

[0010] 2. During the placement process of the glass on the flatness measuring device, it directly contacts and collides with the top of the support block, and the impact force is relatively large. This method will cause the glass to break and be damaged. When the glass is moved to the upper part of the support block and placed down by mechanical equipment or manually, the bottom surface of the glass will first contact the top of the semi-circular block. At this time, the semi-circular block will be squeezed by the glass and move. At the same time, when the semi-circular block moves, it can drive the extrusion block to move. And when the extrusion block moves, it will squeeze the telescopic spring. When the telescopic spring is compressed to the maximum extent, the bottom of the glass can move to the top of the support block. At this time, the glass will not generate a large impact force. Through the semi-circular block and the telescopic spring, the glass can play a buffering effect during the placement process, thereby avoiding the glass directly colliding with the support block, reducing the impact force, and making the glass not easily broken.

Specific embodiments

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figure 1 , Figure 2 and Figure 3 It can be seen that the present utility model provides a technical solution: a flatness measuring device that is convenient to clamp, including: a measuring frame body 1, a display controller 2, a support block 3, a moving cross beam 4, and a laser measurement probe 5. The outside of the measuring frame body 1 is connected with a display controller 2. The surface of the measuring frame body 1 is provided with a support block 3. The top of the measuring frame body 1 is connected with a moving cross beam 4 through a slide rail. The bottom of the moving cross beam 4 is provided with a laser measurement probe 5. The front part of the measuring frame body 1 is provided with a motor 6. A connecting block 7 is welded to the front part of the measuring frame body 1 near the motor 6. A bidirectional lead screw 8 is connected inside the connecting block 7 through a bearing. A bevel gear set 9 is sleeved between the outside of the bidirectional lead screw 8 and the output end of the motor 6. The outside of the bidirectional lead screw 8 is threadedly connected with a slider 10. A clamping plate 11 is installed on the back of the slider 10. Rubber pads 12 are bonded to the opposite sides of the two clamping plates 11. Wear-resistant cloth blocks 13 are bonded to the surface of the rubber pads 12. A guide rod 14 is welded inside the measuring frame body 1. A sliding structure is formed between the clamping plate 11 and the guide rod 14. Two groups of clamping plates 11 are symmetrically arranged about the center of the measuring frame body 1.

[0018] During specific implementation, the flatness measuring device calculates the undulation of the glass surface by the reflection angle of the light emitted by the laser measuring probe 5, so as to determine the flatness of the glass surface. However, the glass placed on the support block 3 is relatively unstable. Therefore, the motor 6 can be started. When the motor 6 rotates forward, it can drive the bevel gear set 9 to engage and rotate. When the bevel gear set 9 rotates, it can drive the bidirectional lead screw 8 to rotate forward. When the bidirectional lead screw 8 rotates forward, it can drive the two groups of sliders 10 to perform threaded sliding towards each other. When the sliders 10 perform threaded sliding, they can drive the clamping plates 11 to move. When the clamping plates 11 move, they can slide through the guide rods 14. And when the clamping plates 11 move, they can drive the rubber pads 12 and the wear-resistant cloth blocks 13 to move. When one side of the wear-resistant cloth block 13 moves to the side surface of the glass, the two groups of clamping plates 11 can quickly clamp the glass, and the rubber pads 12 and the wear-resistant cloth blocks 13 can protect the two sides of the glass to prevent the clamping plates 11 from directly contacting the two sides of the glass.

[0019] Refer to Figure 1 、 Figure 2 and Figure 3 It can be seen that the glass can be quickly clamped and limited by the two groups of clamping plates 11, so that the glass is not likely to slide and shift in position on the support block 3, improving the stability of the glass placement by the flatness measuring device.

[0020] Refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 4 It can be seen that a fixed seat 15 is welded on the surface of the measuring frame body 1 close to the support block 3. An expansion spring 16 is connected inside the fixed seat 15. One end of the expansion spring 16 is connected with a pressing block 17. A guide block 18 is welded at the bottom of the pressing block 17. A semi-circular block 19 is adhered to the top of the pressing block 17. The semi-circular block 19 is made of rubber material. A sliding structure is formed between the guide block 18 and the fixed seat 15.

[0021] During specific implementation, when the glass on the flatness measuring device is being placed, it directly contacts and collides with the top of the support block 3, and the collision force is relatively large. This method will cause the glass to break and be damaged. When the glass is moved to the top of the support block 3 by mechanical equipment or manually and then placed down, the bottom surface of the glass will first contact the top of the semi-circular block 19. At this time, the semi-circular block 19 will be displaced due to the extrusion of the glass. And since the semi-circular block 19 is made of rubber material, when the semi-circular block 19 is extruded, it will deform to a certain extent. At the same time, when the semi-circular block 19 moves, it can drive the pressing block 17 to move. When the pressing block 17 moves, it can drive the guide block 18 to move. And when the pressing block 17 moves, it will squeeze the expansion spring 16, causing the expansion spring 16 to be squeezed and contracted. When the expansion spring 16 is compressed to the maximum extent, the bottom of the glass can move to the top of the support block 3. At this time, the glass will not generate a large collision force.

[0022] Referring to Figure 1 , Figure 2 , Figure 3 and Figure 4 it can be seen that through the semi-circular block 19 and the telescopic spring 16, the glass can have a buffering effect during the placement process, thereby avoiding direct collision between the glass and the support block 3, reducing the collision force, and making the glass not easily broken.

[0023] In summary, when using this easy-to-clamp flatness measuring device, place the glass on the top of the support block 3. The display controller 2 can control the moving crossbeam 4 to move above the glass. At the same time, the light emitted by the laser measurement probe 5 will be reflected back. The flatness measuring device calculates the undulation of the glass surface through the reflection angle of the light, thereby determining the flatness of the glass surface. The flatness measuring device is a prior art and will not be described in detail here. The two sets of clamping plates 11 can quickly clamp the glass, and the rubber pads 12 and the wear-resistant cloth blocks 13 can protect both sides of the glass, avoiding direct contact between the clamping plates 11 and both sides of the glass. The two sets of clamping plates 11 can quickly clamp and limit the glass, making the glass not easily slide or shift in position on the support block 3, improving the stability of the flatness measuring device for placing the glass. When the telescopic spring 16 is compressed to the maximum extent, the bottom of the glass can move to the top of the support block 3. At this time, the glass will not generate a large collision force. Through the semi-circular block 19 and the telescopic spring 16, the glass can have a buffering effect during the placement process, thereby avoiding direct collision between the glass and the support block 3, reducing the collision force, and making the glass not easily broken. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
