Description

Technical Field

[0001] This utility model relates to the field of edge grinding machine technology, and specifically to a screw linkage combination structure for an edge grinding machine. Background Technology

[0002] The double-sided glass edging machine can simultaneously grind and polish both edges of glass sheets. It is widely used in construction, furniture, home appliances, and automotive glass industries. The glass sheet is fed in by a conveyor system, and the double-sided grinding heads simultaneously chamfer, straighten, or shape the edges, ultimately outputting a smooth, chip-free finished product. During processing, the central support directly supports the glass to be edged, especially for large or heavy glass, ensuring its horizontal placement. The grinding heads and their motors are mounted on both the fixed and movable housings; the movable housing can be moved to accommodate different glass sizes.

[0003] The existing method for opening and closing the center bracket involves moving the movable housing and then dragging both sides of the center bracket using two synchronous belts or steel cables. Because the synchronous belts or steel cables have a certain degree of elasticity, they will elongate under stress, leading to inaccurate opening and closing positions of the center bracket, with an error of approximately 10mm. The center bracket may also sometimes collide with the movable housing or grinding head. Furthermore, when the two synchronous belts or steel cables drag the sides of the center bracket, the uneven force on both sides prevents synchronous movement, causing the ends of the center bracket to shift by about 5mm. During high-speed edge grinding, this can easily cause the glass to become misaligned, affecting the edge grinding quality. Utility Model Content

[0004] In order to overcome at least one of the technical problems existing in the prior art, this utility model provides a screw linkage combination structure, which can reduce the offset error of the central bracket during movement, and the central bracket can move synchronously with the two movable box seats, making the opening and closing position of the central bracket more precise.

[0005] A lead screw linkage assembly structure includes a base. Two fixed housing seats and a lead screw power assembly are arranged side-by-side at one end of the base. Guide rails are symmetrically mounted on both sides of the base. A central bracket and two side-by-side movable housing seats are slidably mounted on the guide rails. The central bracket is located between the two fixed housing seats and the two movable housing seats. The lead screw power assembly includes two side-by-side reducers, one of which is connected to a servo motor. A first connecting shaft connects the two reducers. A synchronous transmission device is installed on each side of the base, comprising components mounted side-by-side on the guide rails. The system includes a movable housing lead screw and a central support lead screw on one side; it also includes a gearbox containing three gears arranged side by side with the same number of teeth, with the middle gear acting as an idler gear to transmit motion and power; the movable housing lead screw is connected to the movable housing base via a nut seat, and one end of the movable housing lead screw is connected to the gear and reducer located on one side; the gear located on the other side is connected to the central support lead screw, and the central support lead screw is connected to the central support base via a nut seat; when the servo motor is working, it drives the movable housing lead screw and the central support lead screw to rotate synchronously, and the movable housing base and the central support move synchronously along the guide rail.

[0006] In some embodiments, the movable housing screw and the central bracket screw are mounted on the base via bearing seats, and the movable housing seat and the central bracket seat are slidably connected to the guide rail via sliders.

[0007] In some embodiments, one end of the movable box screw is connected to a second connecting shaft via a coupling, and one end of the second connecting shaft is fixedly engaged with a gear located on one side and is also connected to a reducer.

[0008] In some embodiments, the gearbox is mounted on a fixed housing base via a gearbox seat, a guide rail cover is installed above each guide rail, and a water receiving tray is installed in the middle of the base.

[0009] In some embodiments, the center bracket includes a crossbar with multiple rollers mounted side-by-side on the top of the crossbar, vertical bars symmetrically mounted on both sides of the crossbar, and a center bracket seat mounted on the lower end of the vertical bars.

[0010] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0011] When the servo motor is working, it drives two reducers to work synchronously, and the two drive moving box lead screws and the two center bracket lead screws also rotate synchronously. The moving box seat and the center bracket will move synchronously along the guide rail, which can avoid the center bracket from colliding with the moving box or grinding head.

[0012] During operation, the two central bracket lead screws rotate synchronously, thereby driving the two ends of the central bracket to move synchronously. This reduces the offset error of the central bracket during movement, makes the opening and closing position of the central bracket more precise, and makes it less likely to deviate the glass during high-speed edge grinding, thus improving the edge grinding quality.

[0013] Additional aspects and advantages of this invention will continue to be set forth in the description which follows, and in part will be obvious from the description or may be learned by practice of this invention. Attached Figure Description

[0033] Reference Figures 1-6 A screw linkage assembly structure includes a base 1. Two fixed housing seats 2 and a screw power assembly 3 are arranged side by side at one end of the base 1. Guide rails 4 are symmetrically installed on both sides of the base 1. A central bracket 5 and two side by side movable housing seats 6 are slidably installed on the guide rails 4. The two guide rails 4 are symmetrically arranged along the length direction of the base 1. The two fixed housing seats 2 and the two movable housing seats 6 are symmetrically arranged along the width direction of the base 1. Fixed housings are installed on the fixed housing seats 2, and movable housings are installed on the movable housing seats 6. The central bracket 5 is located between the two fixed housing seats 2 and the two movable housing seats 6.

[0034] The lead screw power assembly 3 includes two reducers 300 arranged side by side. The two reducers 300 are symmetrically arranged along the width direction of the base 1. One reducer 300 is connected to the servo motor 301. A first connecting shaft 302 is connected between the two reducers 300. When the servo motor 301 is working, it drives the two reducers 300 to work synchronously.

[0035] A synchronous transmission device 7 is installed on each side of the base 1, which includes a movable box screw 700 and a central bracket screw 701 installed side by side on one side of the guide rail 4.

[0036] It also includes a gearbox 702, which comprises three gears 702a arranged side by side with the same number of teeth. The middle gear 702a acts as an idler gear to transmit motion and power. The gears 702a on both sides can achieve the same speed and synchronous rotation through the middle gear 702a. The movable gearbox lead screw 700 is connected to the bottom of the movable gearbox base 6 through a nut seat 703. One end of the movable gearbox lead screw 700 is connected to the gear 702a on one side and the reducer 300 in sequence. The gear 702a on the other side is connected to the central bracket lead screw 701. The central bracket lead screw 701 is connected to the bottom of the central bracket base 500 through a nut seat 703.

[0037] When the servo motor 301 is working, it drives the two reducers 300 to work synchronously. The two drive movable box lead screws 700 and the two center bracket lead screws 701 also rotate synchronously. The movable box seat 6 and the center bracket 5 will move synchronously along the guide rail 4. In addition, the movable box lead screws 700 and the center bracket lead screws 701 can be designed with different diameters and different leads (pitches), so that the center bracket 5 can move synchronously with the two movable box seats 6 but at different speeds. This application can reduce the offset error of the center bracket 5 during movement, make the opening and closing position of the center bracket 5 more accurate, reduce the failure rate, and simplify maintenance.

[0038] In some embodiments, the movable box screw 700 and the central bracket screw 701 are mounted on the base 1 via bearing seats 11. There are two bearing seats 11, which are symmetrically mounted at both ends. The above structure provides good support and low resistance during rotation. The movable box seat 6 and the central bracket seat 500 are slidably connected to the guide rail 4 via a slider 8. The above structure is simple and the sliding is smooth and stable.

[0039] In some embodiments, one end of the movable lead screw 700 is connected to the second connecting shaft 705 via a coupling 704. One end of the second connecting shaft 704 is sleeved and fixed to a gear 702a located on one side, and is also connected to the reducer 300. Mechanical installation is difficult to achieve zero deviation. The coupling 704 can absorb radial and angular errors. If the gear meshing vibration of the reducer 300 is directly transmitted to the lead screw, it will reduce the positioning accuracy. The torque limiting function of the coupling 704 can prevent the lead screw balls from being crushed.

[0040] In some embodiments, the gearbox 702 can be tightened onto the fixed housing base 2 with multiple screws via the gearbox base 702b, making installation and disassembly convenient. Each guide rail 4 is equipped with a guide rail cover 9 to reduce the entry of liquid and dust, and to protect the workers from being pinched. A water tray 10 is installed in the middle of the base 1 to hold the liquid and debris generated during processing, making it easy to clean.

[0041] In some embodiments, the center bracket 5 includes a crossbar 501, with multiple rollers 502 mounted side by side on the top of the crossbar 501 to support the glass and reduce damage to it; vertical bars 503 are symmetrically mounted on both sides of the crossbar 501, and the center bracket seat 500 is mounted on the lower end of the vertical bars 503. The above structure is simple, convenient, stable and durable.

[0042] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification. Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the claims and their equivalents.
