Description

Technical Field

[0001] This utility model relates to the technical field of glass edging devices, specifically a precision edging device for narrow strip glass edges. Background Technology

[0002] Glass edging equipment is a mechanical device used to cut, grind, and polish the edges of glass, aiming to improve edge safety, smoothness, and aesthetics. It is mainly divided into straight edge grinding machines (for processing straight edges and corners of flat glass) and irregular edge grinding machines (for processing irregular edges such as circles and ovals). Its core process usually includes multiple steps such as rough grinding, fine grinding, and polishing, which are achieved through diamond or resin grinding wheels.

[0003] Glass edging equipment is a key piece of equipment for improving the quality of glass products, but it still has certain problems: 1) Traditional single-stage adjustment mechanisms (such as manual lead screws or ordinary cylinders) cannot simultaneously meet the needs of large-stroke rapid positioning and precise adjustment, resulting in repeated and time-consuming adjustments during the edging process of narrow strip glass, and dimensional deviations are easily caused by cumulative errors; 2) Rigid clamps lack buffer design, and clamping force control depends on worker experience. Thin and brittle glass is prone to micro-cracks or edge chipping due to stress concentration during the clamping process; 3) Angle adjustment requires disassembly and reassembly or reliance on indexing plates, which is time-consuming and lacks a rigid locking mechanism. Angle drift is prone to occur during grinding, which cannot meet the standardized operation requirements of multi-angle precision edging. Therefore, in view of the above situation, it is urgent to develop a precision edging device for narrow strip glass edges to overcome the shortcomings in current practical applications and meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a precision edge grinding device for narrow strip glass to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision edge grinding device for narrow strip glass, comprising a cabinet, a grinding mechanism mounted on the cabinet for grinding the strip glass, a clamp located above the grinding mechanism for holding the strip glass, a fine adjustment mechanism for mounting the clamp and driving its lifting and lowering, a coarse adjustment mechanism for mounting the fine adjustment mechanism and driving its lifting and lowering, and a suspension for mounting the coarse adjustment mechanism.

[0006] In practical use, the top-mounted fixture layout and the coordinated design of the coarse / fine adjustment mechanisms ensure that narrow strip glass is stably clamped throughout the grinding process. The coarse adjustment mechanism uses a cylinder to drive the roller linear guide module for rapid lifting and positioning, while the fine adjustment mechanism uses an electric cylinder to control the ball linear guide module for precise micro-adjustment. Combined with the pneumatic angle adjustment of the rotating frame, the eccentric locking mechanism of the fixture for quick clamping, and the spring-buffered side clamping, the positioning accuracy, processing stability, and operating efficiency of narrow strip glass edge grinding are significantly improved, effectively solving the industry pain points of thin and brittle glass being prone to edge chipping and traditional adjustment being time-consuming.

[0007] The coarse adjustment mechanism includes: a lifting frame a, a roller linear guide module for connecting the lifting frame a and the suspension, and a first drive element for driving the lifting frame a to move up and down along the roller linear guide module.

[0008] The fine adjustment mechanism includes: a lifting frame b, a ball linear guide module for connecting the lifting frame b and the lifting frame a, a second drive element for driving the lifting frame b to move up and down along the ball linear guide module, a rotating frame rotatably mounted on the lifting frame b, and a rotary drive element mounted on the lifting frame b for driving the rotating frame to rotate; wherein, the lifting frame b is provided with a pneumatic positioning pin, and the rotating frame is provided with a positioning hole adapted to the pneumatic positioning pin;

[0009] In practical use, the lifting frame a of the coarse adjustment mechanism and the roller linear guide module achieve large-stroke rapid lifting and positioning, and the cylinder provides efficient initial adjustment; the lifting frame b of the fine adjustment mechanism and the ball linear guide module complete precise micro-adjustment under the drive of the electric cylinder, while the rotating frame realizes the grinding angle adjustment under the action of the rotating cylinder, and the rigid locking of the pneumatic positioning pin and the positioning hole ensures the stability of the angle.

[0010] The fixture includes: a base plate mounted on the bottom of the rotating frame, a panel fixed on the base plate, and a clamping plate located between the base plate and the panel for pressing the strip glass. The base plate is provided with a backing for glass positioning. The fixture also includes a limiting component for limiting the end of the strip glass and a side clamping component for clamping the side of the strip glass.

[0011] In practical use, the direct connection design between the base plate and the rotating frame ensures accurate transmission of the grinding angle, the backrest achieves glass reference positioning, and the clamping plate vertically presses the glass between the base plate and the panel to prevent displacement; together with the limiting component to limit the glass end and the side clamping component to clamp, it solves the problems of positioning drift, edge breakage and low clamping efficiency of narrow strip glass in the edge grinding process.

[0012] Preferably, the first driving element includes a cylinder, the second driving element includes an electric cylinder, and the rotary driving element includes a rotary cylinder.

[0013] In practical use, the coarse adjustment mechanism driven by the cylinder achieves a large stroke and rapid response, improving the initial positioning efficiency; the electric cylinder controls the fine adjustment mechanism to complete the precision displacement, ensuring the stability of the grinding depth; the rotary cylinder, combined with the rigid locking of the pneumatic positioning pin and the positioning hole, achieves efficient switching and zero drift locking of the grinding angle. The air-electric hybrid drive system combines speed, accuracy and reliability, significantly reducing the adjustment time and operational intensity of narrow strip glass in complex grinding processes.

[0014] Preferably, a number of positioning holes are radially equidistantly distributed along the rotation axis of the rotating frame.

[0015] In practical use, the modular positioning of the rotation angle is achieved through radially equidistant positioning holes, allowing specific angles to be preset according to processing requirements. Combined with the rigid locking of the pneumatic positioning pins, the efficiency of angle switching is ensured while eliminating the cumulative error of traditional manual adjustment. The equidistant layout ensures uniform force on the positioning holes, avoids local wear, and improves system durability. The modular hole design has both standardization and customization expansion capabilities, and is fully compatible with the multi-angle precision edge grinding process of narrow strip glass.

[0016] Preferably, at least three connecting posts for connection are fixed at the four corners between the base plate and the panel, a backing is installed on the side of the base plate adjacent to the panel, and a clearance groove is provided on the bottom edge of the panel.

[0017] Preferably, the clamping plate includes an eccentric lock and a sliding shaft. The clamping plate is slidably connected to the panel through at least two parallel sliding shafts. The rotation shaft of the eccentric lock is fixed to the clamping plate, and the lock end can be engaged with the edge of the panel.

[0018] In practical use, the parallel sliding cooperation between the double sliding shaft and the panel ensures that the clamping plate moves horizontally without deviation, so that the glass is evenly pressed; the cam force amplification principle of the eccentric lock makes the locking end press down on the edge of the panel to form a self-lock when the rotating shaft is fixed to the clamping plate, so that the glass can be pressed / released by one hand, which solves the problem of low efficiency of manual clamping of narrow strip glass and edge micro-cracks caused by uneven force.

[0019] Preferably, the limiting component includes: two mounting brackets a fixed on one side of the base plate, a slide rod a fixed between the two mounting brackets a, a slider a slidably sleeved on the slide rod a, a screw rod rotatably mounted on the mounting bracket a parallel to the slide rod a, a limiting block slidably disposed on the other side of the mounting bracket a and fixedly connected to the slider a, a threaded sleeve sleeved on the screw rod and fixedly connected to the limiting block; and a handle a fixedly disposed at the end of the screw rod.

[0020] In practical use, the screw and sleeve drive, along with the rigid guiding design of the slide bar a and slider a, drive the limit block to achieve fine adjustment when the handle is turned. Combined with the self-locking of the screw sleeve and the interference fit of the slider a, the backlash is eliminated. The double-sided mounting bracket a supports the bending stability, fundamentally solving the drift problem of the positioning of the narrow strip glass end.

[0021] Preferably, the side clamping assembly includes: two mounting brackets b fixed on one side of the base plate, a slide rod b fixed between the two mounting brackets b, a slider c slidably sleeved on the slide rod b, a pull rod slidably passing through the middle position of the mounting bracket b, a slider b fixed at the end of the pull rod, a clamping block slidably disposed on the other side of the mounting bracket b, and a spring sleeved on the pull rod; the slider b and slider c are fixedly connected to the clamping block.

[0022] In practical use, the slider c is driven to slide along the slider b by the rigid linkage between slider b and the pull rod, so that the clamping block contacts the side of the glass; the spring provides a constant elastic clamping force on the pull rod. When the glass expands due to heat or fluctuates in thickness, the spring automatically compensates for the displacement, eliminates the micro-cracks caused by rigid compression of narrow strip glass, and reduces the breakage rate.

[0023] Preferably, the base plate is provided with at least two elongated first sliding grooves parallel to the backing mountain, and the limiting block is provided with a connecting boss extending towards the base plate on one side. At least two of the bosses pass through the first sliding grooves and are fixedly connected to the slider a and the screw sleeve. The base plate is provided with at least two rectangular second sliding grooves perpendicular to the backing mountain, and the clamping block is provided with a connecting boss extending towards the base plate on one side. At least two of the bosses pass through the second sliding grooves and are fixedly connected to the slider b and the slider c.

[0024] Preferably, the polishing mechanism is a rotary glass polishing device.

[0025] Compared with the prior art, this utility model provides a precision edge grinding device for narrow strip glass, which has the following advantages:

[0026] The roller guide rail driven by a cylinder enables rapid coarse adjustment, while the ball guide rail controlled by an electric cylinder enables fine adjustment. Combined with the modular locking structure of the rotating frame angle, this significantly improves the positioning efficiency and grinding accuracy of narrow strip glass. The fixture uses an eccentric lock for quick clamping, and with the screw precision limit and spring buffer side clamping, it completely eliminates the problem of glass edge chipping while ensuring repeatability and positioning accuracy. The overall structure solves the problems of glass breakage during high-speed edge grinding, cumbersome angle adjustment, and poor edge uniformity, greatly reducing clamping time.

[0043] In practical use, the upper-mounted layout of the clamp 60 and the coordinated design of the coarse adjustment mechanism 40 / fine adjustment mechanism 50 ensure that the narrow strip glass 70 is stably clamped during the grinding process. The coarse adjustment mechanism 40 uses a cylinder 430 to drive the roller linear guide module 420 to achieve rapid lifting and positioning. The fine adjustment mechanism 50 uses an electric cylinder 530 to control the ball linear guide module 520 to complete precise micro-adjustment. Combined with the pneumatic angle adjustment of the rotating frame 540, the clamp's eccentric locking buckle 621 for quick clamping, and the spring buffer side clamping 657, the positioning accuracy, processing stability, and operation efficiency of the narrow strip glass edge grinding are significantly improved, effectively solving the industry pain points of thin and brittle glass being prone to edge breakage and traditional adjustment being time-consuming.

[0044] The coarse adjustment mechanism 40 includes: a lifting frame a410, a roller linear guide module 420 for connecting the lifting frame a410 and the suspension 30, and a first driving element for driving the lifting frame a410 to move up and down along the roller linear guide module 420.

[0046] In practical use, the lifting frame a410 of the coarse adjustment mechanism 40 and the roller linear guide module 420 achieve large-stroke rapid lifting and positioning, and the cylinder 430 provides efficient initial adjustment; the lifting frame b510 of the fine adjustment mechanism 50 and the ball linear guide module 520 complete precise micro-adjustment under the drive of the electric cylinder 530, while the rotating frame 540 achieves grinding angle adjustment under the action of the rotating cylinder 550, and the rigid locking of the pneumatic positioning pin 511 and the positioning hole 541 ensures the stability of the angle.

[0047] The clamp 60 includes: a base plate 630 mounted on the bottom of the rotating frame 540, a panel 610 fixed on the base plate 630, and a clamping plate 620 located between the base plate 630 and the panel 610 for pressing the strip glass. The base plate 630 is provided with a backing 631 for positioning the glass. The clamp 60 also includes a limiting component 640 for limiting the end of the strip glass and a side clamping component 650 for clamping the side of the strip glass.

[0048] In practical use, the direct connection design between the base plate 630 and the rotating frame 540 ensures accurate transmission of the grinding angle. The backrest 631 achieves glass reference positioning, and the clamping plate 620 vertically presses the glass between the base plate 630 and the panel 610 to prevent displacement. With the help of the limiting component 640 to limit the glass end and the side clamping component 650 to clamp, the problems of positioning drift, edge breakage and low clamping efficiency of narrow strip glass during the edge grinding process are solved.

[0049] Preferably, the first driving element includes a cylinder 430, the second driving element includes an electric cylinder 530, and the rotary driving element includes a rotary cylinder 550.

[0050] In practical use, the coarse adjustment mechanism 40 is driven by the cylinder 430 to achieve a large stroke and fast response, improving the initial positioning efficiency; the electric cylinder 530 controls the fine adjustment mechanism 50 to complete the precision displacement, ensuring the stability of the grinding depth; the rotary cylinder 550, combined with the rigid locking of the pneumatic positioning pin 511 and the positioning hole 541, realizes the efficient switching and zero drift locking of the grinding angle. The air-electric hybrid drive system combines speed, accuracy and reliability, significantly reducing the adjustment time and operation intensity of narrow strip glass in complex grinding processes.

[0051] Preferably, a plurality of positioning holes 541 are radially equidistantly distributed along the rotation axis of the rotating frame 540.

[0052] In practical use, the rotation angle is modularly positioned through radially equidistant positioning holes 541, allowing specific angles such as 30°, 45°, and 60° to be preset according to processing requirements. Combined with the rigid locking of the pneumatic positioning pin 511, the efficiency of angle switching is ensured while eliminating the cumulative error of traditional manual adjustment. The equidistant layout ensures uniform force on the positioning holes, avoids local wear, and improves system durability. The modular hole design has both standardization and customization expansion capabilities, and is fully compatible with the multi-angle precision edge grinding process of narrow strip glass.

The rotation shaft of the eccentric lock 621 is fixed to the clamping plate 620, and the lock end can be engaged with the edge of the panel 610.

[0055] In practical use, the parallel sliding cooperation between the double sliding shaft 622 and the panel 610 ensures that the clamping plate 620 moves horizontally without deviation, so that the glass is evenly pressed; the cam force amplification principle of the eccentric lock 621, when the rotating shaft is fixed to the clamping plate 620, forms a self-lock by pressing down on the edge of the panel 610 through the lock end, so as to realize the glass clamping / release by a single hand pressing action, which solves the problem of low efficiency of manual clamping of narrow strip glass and edge micro-cracks caused by uneven force.

[0056] Preferably, the limiting component 640 includes: two mounting brackets a642 fixed to one side of the base plate 630, a slide rod a644 fixed between the two mounting brackets a642, a slider a647 slidably sleeved on the slide rod a644, a screw 643 rotatably mounted on the mounting bracket a642 parallel to the slide rod a644, a limiting block 641 slidably disposed on the other side of the mounting bracket a642 and fixedly connected to the slider a647, a threaded sleeve 645 sleeved on the screw 643 and fixedly connected to the limiting block 641; and a handle 646a fixedly disposed at the end of the screw 643.

When the handle 646 is turned, the limit block 641 is driven to achieve fine adjustment. Combined with the self-locking of the screw sleeve 645 and the interference fit of the slider a647, the backlash is eliminated. The double-sided mounting bracket a642 supports and ensures bending stability, thus fundamentally solving the drift problem of the positioning of the narrow strip glass end.

[0058] Preferably, the side clamping assembly 650 includes: two mounting brackets b652 fixed on one side of the base plate 630, a slide rod b655 fixed between the two mounting brackets b652, a slider c654 slidably sleeved on the slide rod b655, a pull rod 656 slidably passing through the middle position of the mounting bracket b652, a slider b653 fixed at the end of the pull rod 656, a clamping block 651 slidably disposed on the other side of the mounting bracket b652, and a spring 657 sleeved on the pull rod 656; the slider b653 and slider c654 are fixedly connected to the clamping block 651.

[0059] In practical use, the slider c654 is driven to slide along the slider b655 by the rigid linkage between the slider b653 and the pull rod 656, so that the clamping block 651 contacts the side of the glass; the spring 657 provides a constant elastic clamping force on the pull rod 656. When the glass expands due to heat or fluctuates in thickness, the spring automatically compensates for the displacement, eliminates the micro-cracks caused by rigid compression of the narrow strip glass, and reduces the breakage rate.

[0060] Preferably, the base plate 630 is provided with at least two elongated first grooves parallel to the backrest 631, the limiting block 641 is provided with a connecting boss extending toward the base plate 630 on one side, and at least two of the bosses pass through the first grooves and are fixedly connected to the slider a647 and the threaded sleeve 645.

[0061] Preferably, the polishing mechanism 20 is a rotary glass polishing device.

[0062] It should be added here that, Figure 2 , Figure 5 , Figure 6 , Figure 8 In this context, A represents a strip of glass.

[0063] Working principle: First, rotate handle a646 to adjust the height of limit block 641. Then, pull rod 656 to move clamping block 651 away from backrest 631. Next, press the narrow strip of glass against base plate 630 and backrest 631 for initial positioning. Once the strip of glass is in place, release it. Finally, press down clamping plate 620 and lock eccentric lock 621 for fixation. At this point, clamping is complete. The coarse adjustment mechanism 40 and fine adjustment mechanism 50 drive clamping 60 and strip of glass to descend, bringing them close to and contacting the grinding disc of grinding mechanism 20 to achieve edge grinding. When coarse adjustment mechanism 40 and fine adjustment mechanism 50 are working, cylinder 430 first drives lifting frame A410 along roller linear guide module 42. 0. Quickly adjust to the initial height. At this time, the strip glass is close to the grinding disc of the grinding mechanism 20. Then, the electric cylinder 530 controls the lifting frame B510 to complete the fine adjustment distance along the ball linear guide module 520, thereby driving the strip glass to slowly contact the grinding disc of the grinding mechanism 20 to realize the edge grinding operation. When it is necessary to adjust the edge grinding angle, the rotary cylinder 550 drives the rotary frame 540 to rotate to the target angle, and then the pneumatic positioning pin 511 is inserted into the positioning hole 541 for rigid locking.
