Glass milling device with position adjustment

Abstract

The application provides a glass milling device convenient for position adjustment, and relates to the technical field of glass milling, which comprises a base, a translation assembly, an adjusting mechanism and a rotating mechanism. The adjusting mechanism realizes local lifting and angle fine adjustment of the glass through cooperation of a fixing plate, an eccentric groove, a single-layer ring and a limiting disc. The rotating mechanism realizes stable support of the glass through cooperation of a four-corner sleeve and a rotating disc. The device uses a handle to pull a sliding sleeve to lift the eccentric wheel upward to lift the local area of the glass. By rotating the handle to drive the outer gear and the inner wheel to rotate the eccentric wheel, the glass is deflected in angle around the opposite rotating disc fulcrum. The traditional overall flat pushing coarse adjustment mode overcoming static friction is changed into low-resistance rotating fine adjustment after local lifting. The adjusting error caused by overcoming the maximum static friction force is effectively avoided, and the convenience and precision of glass positioning are significantly improved.

Description

Technical Field

[0001] This invention relates to the field of glass milling technology, and more specifically, to a glass milling apparatus that is easy to adjust in position. Background Technology

[0002] In existing technologies, when glass milling devices position glass, the glass is usually placed flat on the worktable first. Then, a horizontal pushing force is applied manually from the side to move the glass as a whole to achieve fine-tuning of its position. However, this method of pushing as a whole requires the operator to first overcome the maximum static friction between the glass and the worktable. Once the glass starts to slide, the pushing force needs to be reduced quickly to control the amount of movement. Since it is difficult for manual operation to accurately grasp the critical point of the transition of the pushing force from static friction to dynamic friction, the glass often displaces far more than expected at the moment of starting, or slips additionally due to inertia when stopping, resulting in a significant decrease in the accuracy of fine-tuning.

[0003] Even more challenging is that when the glass area is large or the surface is tightly attached to the tabletop, the maximum static friction increases dramatically. To push the glass, the operator has to apply a greater initial force, which makes the impact of overcoming friction more intense. The glass is prone to jumping or deflecting, which not only fails to achieve the expected micro-adjustment, but may also cause the glass edges to crack or scratch the tabletop due to excessive local force. At the same time, frequent push-pull also significantly reduces positioning efficiency and operational convenience. Therefore, the existing lateral push-adjustment method has obvious defects in terms of accuracy, safety and convenience. Summary of the Invention

[0005] To achieve the above objectives, the present invention provides the following technical solution: a glass milling device for easy position adjustment, comprising a fixed base, on which a translation component is mounted; and an adjustment mechanism mounted on the translation component, the adjustment mechanism comprising a fixed plate mounted on the translation component, wherein eccentric grooves are respectively formed on the four sides of the fixed plate, and a top rod is respectively provided in each eccentric groove, an inner wheel is fitted in the eccentric groove, and two coaxial inner rings are respectively provided on both sides of the inner wheel, the two inner rings are respectively fitted in contact with the outer wall of the top rod, an external gear is fixedly arranged between the two inner rings, the inner diameter of the external gear is larger than the diameter of the inner ring, the external gear meshes with two drive wheels, and a rotation mechanism is provided on the fixed plate.

[0006] Preferably, each of the eccentric grooves has a symmetrical sleeve at its lower end, each of the symmetrical sleeves has an embedded groove, each of the embedded grooves has a sliding sleeve slidably disposed therein, each of the sliding sleeves has a rotating shaft disposed therein, and the drive wheel is sleeved on the rotating shaft.

[0007] Preferably, a handle is coaxially provided on the side wall of the drive wheel, a through hole is provided in the handle, the shaft is inserted into the through hole, and multiple anti-slip grooves are provided on the circular outer wall of each handle.

[0008] Preferably, the width of the drive wheel is equal to the length between the adjacent surfaces of the two inner rings, and the two circular surfaces of the drive wheel are respectively attached to the inner walls of the two inner rings.

[0009] Preferably, each of the sliding sleeves is provided with a spring, the other end of which is connected to the inside of the symmetrical sleeve, and the multiple springs are of the same size.

[0010] Preferably, the inner wheel has multiple eccentric springs on its annular outer wall, and the other end of each of the multiple eccentric springs is connected to an eccentric wheel. The inner wheel has two double-layer rings coaxially arranged on its circular outer wall, and the eccentric wheel has a single-layer ring coaxially arranged on its annular inner wall.

[0011] Preferably, the single-layer coil is located between the two double-layer coils, and the two double-layer coils are respectively located on the inner walls of the two sets of eccentric springs.

[0012] Preferably, a limiting disc is coaxially provided at the end of the top rod away from the eccentric groove, and the limiting disc is attached to the outer wall of the inner wheel.

[0013] Preferably, the rotating mechanism includes four corner sleeves installed on the four corners of the fixed plate, each corner sleeve having a turntable rotatably mounted thereon, and a glass body being fitted onto the multiple turntables, the glass body pressing against the multiple eccentric wheels.

[0014] Preferably, the base is provided with a movable component, and the movable component is provided with a milling tool.

[0015] Compared with the prior art, the present invention provides a glass milling device that is easy to adjust in position, and has the following beneficial effects: This invention achieves localized lifting and low-resistance rotational fine-tuning of the glass through the coordination of the eccentric wheel and eccentric spring in the adjustment mechanism and the transmission design of the handle and external gear. When the glass angle needs to be adjusted, the operator pulls the handle to move the sliding sleeve outward, the internal wheel lifts up and pushes the eccentric wheel to lift a local area of ​​the glass off the turntable surface, drastically reducing the contact area between the glass and the support surface. Then, the operator rotates the handle to drive the external gear and the internal wheel to rotate, and the eccentric wheel causes the glass to deflect at an angle around the fulcrum on the opposite side that has not been lifted. Since the glass only slides on a few small eccentric wheels rather than the entire bottom surface rubbing against the worktable, the required rotational torque is greatly reduced. The operator can easily achieve precise angle adjustments with small amplitudes, completely solving the problems of displacement overshoot, inertial slippage, and glass edge chipping caused by overcoming maximum static friction in the traditional lateral pushing method.

[0016] The local lifting adjustment structure constructed in this invention avoids deflection or jumping caused by uneven thrust during the overall translation of the glass. The independent adjustment units set on the four sides can lift and rotate each edge of the glass separately. The operator only needs to pull the handle and rotate the corresponding side that needs adjustment to complete the angle correction on that side without moving the entire glass. At the same time, multiple eccentric wheels always maintain elastic contact with the bottom surface of the glass under the action of the glass's own weight. The lifting height only needs to make the glass partially detach from the large area of ​​contact. After the adjustment is completed, the handle spring is released to allow the eccentric wheels to automatically reset, and the glass rests stably on the turntable again. The entire adjustment process is continuous and controllable and does not damage the glass surface.

[0017] This invention integrates glass support, local lifting, and angle fine-tuning into a single mechanical structure. The turntable acts as a stable fulcrum during glass adjustment and remains a milling support point after adjustment, eliminating the need for additional locking devices. A flexible pad can be added to the contact surface between the eccentric wheel and the glass to prevent scratches. The anti-slip groove on the handle ensures a comfortable operating feel. The spring stiffness can be selected according to the weight of the glass to accommodate workpieces of different specifications. At the same time, each adjustment unit works independently without interfering with each other, providing an efficient, safe, and easy-to-operate solution for precise positioning before glass milling, significantly improving the production efficiency and yield of deep glass processing.

[0026] 2.2 Rotating Mechanism 31 The rotating mechanism 31 is the core unit that supports the glass and allows it to rotate. It includes four corner sleeves 32 installed on the four corners of the fixed plate 22. Each corner sleeve 32 is rotatably mounted with a turntable 33. A glass body 34 is attached to the multiple turntables 33. The glass body 34 is pressed against the upper surface of multiple eccentric wheels 218. A moving component 35 is provided on the base 11, and a milling tool 36 for milling the glass is provided on the moving component 35.

[0027] 3. Working process and principle of the device The working process and principle of the glass milling device with adjustable position are as follows: Before milling the glass body 34, its position needs to be precisely adjusted. The four corners of the glass body 34 are supported on four turntables 33, while the middle area of ​​the glass body 34 is pressed against multiple eccentric wheels 218. Due to the large weight of the glass, it can remain stable on the turntables 33 without additional clamping. When it is necessary to adjust the angle of a certain side, the operator holds the handle 213 on the corresponding side with one hand and pulls the sliding sleeve 211 outward along the symmetrical sleeve 29, so that the drive wheel 28 and the external gear 27 are engaged. Simultaneously moving outwards, at this time, because the top rod 24 is attached to multiple inner rings 26 and the drive wheel 28 is engaged with the external gear 27, pulling one side handle 213 will drive the sliding sleeve 211 on the other side to slide towards the axis. The inner wheel 25 changes due to the positional relationship between the top rod 24 and the drive wheel 28. When the handle 213 is pulled outwards, the highest point of the inner wheel 25 moves upwards. When not pulled, the pressure of the glass body 34 has already caused the two double-layer rings 219 to press against the eccentric wheel 218. After pulling, the eccentric wheel 218 is pushed upwards synchronously by the eccentric spring 217, thereby making The glass body 34 on this side is partially raised, and at this time, the glass body 34 is in an eccentric support state. Two corners on this side are raised while the two corners on the other side are still pressed against the turntable 33. The operator then turns the handle 213, which drives the drive wheel 28 to rotate. The drive wheel 28 drives the inner wheel 25 and the eccentric wheel 218 to rotate around its axis through the external gear 27. Due to the eccentric structure of the eccentric wheel 218 and the fact that the glass body 34 has been partially raised, the glass body 34 will deflect at an angle with the farthest fulcrum (i.e., the turntable 33 on the opposite side that has not been raised) as the center when rotating, thereby realizing the glass body The glass body 34 can be adjusted in minute angles. Since the lifting height only requires the glass to be removed from the large area of ​​contact with the worktable, the friction is greatly reduced. The rotation process is easy and controllable. After the required angle is achieved, the handle 213 is released, the spring 216 resets the sliding sleeve 211, and the eccentric wheel 218 returns to its initial support state under the weight of the glass. The glass body 34 is then placed stably on the turntable 33 again, completing the angle fine adjustment. Subsequently, the glass is moved to the milling machine 36 for milling through the translation component 12. The same method can be used to adjust the glass independently on other sides, achieving multi-directional angle fine adjustment.

[0028] Working principle summary: This invention achieves partial lifting of the glass through the cooperation of the eccentric wheel 218 and the eccentric spring 217 in the adjustment mechanism 21. The meshing transmission of the drive wheel 28 and the external gear 27 drives the eccentric wheel 218 to rotate, causing the glass to deflect at an angle around the opposite fulcrum. This transforms the rough method of overall flat pushing to overcome static friction into low-resistance rotational fine adjustment after partial lifting, significantly improving the accuracy of glass positioning and the convenience of operation.

[0029] Example 2 In another optional embodiment, a flexible rubber pad can be provided on the contact surface between the eccentric wheel 218 and the glass body 34 to prevent scratches. The anti-slip groove 215 on the handle 213 can be designed with different depths to adapt to different operating habits. The stiffness of the spring 216 can be selected according to the weight of the glass. A vacuum suction cup can also be provided on the turntable 33 to enhance the stability during milling. A digital angle display instrument can be installed on the fixed plate 22 to facilitate accurate reading of the adjustment amount.
