Description

Technical Field

[0001] The invention relates to the field of glass processing, and in particular to a linear drive mechanism and an opening and closing motion mechanism of a glass edge grinding machine. Background Art

[0002] In the field of glass processing, the edges of the glass need to be ground after cutting to meet the final size and other processing requirements. This processing requires relatively high precision, and since the impact force during the processing is very large, the technical requirements for the glass positioning and fixing mechanism are relatively high.

[0003] In the prior art, the base of the opening and closing motion mechanism is first slidably connected to the frame, a through screw hole is provided on the opening and closing motion mechanism and a screw is threadedly connected thereto, and then a motor is used to drive the screw to rotate, thereby driving the opening and closing motion mechanism to move in the horizontal direction. In actual use, due to the large impact force during the processing process, the screw is easily worn, and the entire screw needs to be replaced once replaced, thereby increasing the cost of use. Therefore, a linear drive mechanism with a simple structure, relatively low cost of use and relatively low maintenance cost after loss, and an opening and closing motion mechanism for a glass edge grinding machine are needed. Summary of the invention

[0004] The main purpose of the present invention is to provide a linear drive mechanism and a glass edge grinding machine opening and closing motion mechanism which have a simple structure, relatively low use cost and relatively low maintenance cost after loss.

[0005] The present invention proposes a linear drive mechanism, comprising a worm with helical teeth, a rack and a drive motor that drives the worm to rotate, wherein the drive shaft of the drive motor, the worm and the rack are arranged in parallel, the helical teeth are formed by a plurality of spiral threads arranged side by side and at equal intervals, the helical teeth are meshed with the rack teeth arranged on the rack, and when the worm rotates, the rack teeth cooperate with the helical teeth, so that the worm moves linearly along the length direction of the rack.

[0006] Preferably, it also includes a driving mechanism housing, a coupling and a gear box, the coupling is arranged in the driving mechanism housing, the gear box is arranged on the outside of the driving mechanism housing, the driving motor is connected to one end of the coupling through the gear box, and the other end of the coupling is connected to the worm.

[0007] Preferably, a driving mechanism housing inner cavity is provided inside the driving mechanism housing, an inner partition is provided in the middle of the driving mechanism housing inner cavity, and the driving mechanism housing inner cavity is divided into a first inner cavity and a second inner cavity by the inner partition; The coupling is arranged in the first inner cavity, and the worm is arranged in the second inner cavity.

[0008] Preferably, the worm comprises a rotating shaft and a worm body, and the worm body is fixedly connected to the outer side of the rotating shaft; One end of the rotating shaft extends out of the driving mechanism housing and the other end of the rotating shaft passes through the inner partition and extends into the first inner cavity, and both ends of the rotating shaft are rotatably connected to the driving mechanism housing through a first limiting member and a second limiting member respectively; The rotating shaft is fixedly connected to the coupling in the first inner cavity.

[0009] Preferably, it further comprises a first connecting bearing and a second connecting bearing, wherein the second connecting bearing is arranged between the rotating shaft and the driving mechanism housing, and the first connecting bearing is arranged between the rotating shaft and the inner partition.

[0010] Preferably, the rack is formed by splicing a plurality of rack bodies.

[0011] The present invention provides an opening and closing motion mechanism of a glass edge grinding machine, comprising a frame, a connecting seat and a linear drive mechanism; The frame is provided with a connecting rail, the connecting seat is slidably connected to the connecting rail, and the positioning mechanism is provided on the connecting seat and fixedly connected to the connecting seat; The frame is provided with a connecting boss, and the side of the connecting boss is provided with a rack. When the driving motor drives the worm to rotate, the rack teeth cooperate with the spiral teeth, so that the worm moves linearly along the length direction of the rack, thereby making the connecting seat move horizontally on the frame, thereby adjusting the relative position of the connecting seat on the frame to adapt to the size of the glass to be processed.

[0012] The beneficial effects of the linear drive mechanism and the opening and closing motion mechanism of the glass edge grinding machine of the present invention are as follows: By using the worm and the rack together, the linear drive mechanism can drive the connecting seat to move in the horizontal direction. Compared with the existing technology, the cost is relatively lower and the structure is relatively simpler.

[0013] The worm is arranged on the side of the rack and is connected with the rack teeth. Since the rack is relatively wide, the contact surface between the worm and the rack is only one-third under normal conditions. When in use, the relative height between the linear drive mechanism and the rack can be adjusted, thereby adjusting the relative height between the worm and the rack, so that racks of different heights can be used separately. In actual use, the rack can be divided into three layers: upper, middle and lower, thereby greatly reducing the cost of use.

[0014] A rack made of multiple rack bodies is used. Since most of the rack bodies are not used during use, when the rack body on the rear side is worn, the unworn rack body in the same machine can be replaced, thereby reducing the time and material costs of frequent replacement.

[0016] The realization of the purpose, functional features and advantages of the present invention will be further explained in conjunction with embodiments and with reference to the accompanying drawings. DETAILED DESCRIPTION

[0017] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0018] Reference Figures 1 to 6 , an embodiment of the linear drive mechanism and the opening and closing motion mechanism of the glass edge grinding machine of the present invention is proposed: A glass edge grinding machine opening and closing motion mechanism comprises a frame 1, a connecting seat 4 and two linear drive mechanisms 3.

[0019] Two connecting bosses 11 are arranged on the top of the frame 1, and a connecting track 12 is arranged on the top of the connecting bosses 11. A rack 6 is arranged on the opposite side of the two connecting bosses 11, and the rack 6 is spliced ​​by a plurality of rack bodies 61. The linear drive mechanism 3 is arranged at the bottom of the connecting seat 4 and is arranged close to the two connecting bosses 11, and the positioning mechanism 5 is arranged on the top of the connecting seat 4.

[0020] The linear drive mechanism 3 includes a drive mechanism housing 33, a drive motor 31, a worm 35, a coupling 34 and a gear box 32. A housing opening is provided on one side of the drive mechanism housing 33, and a drive mechanism housing inner cavity is provided on the inner side of the drive mechanism housing 33. An inner partition 331 is provided in the middle of the drive mechanism housing inner cavity, and the drive mechanism housing inner cavity is divided into a first inner cavity 332 and a second inner cavity 333 by the inner partition 331. The coupling 34 is provided in the first inner cavity 332, and the worm 35 is provided in the second inner cavity 333. The gear box 32 and the drive motor 31 are provided on the outer side of the drive mechanism housing 33. The drive motor 31 is connected to one end of the coupling 34 through the gear box 32, and the other end of the coupling 34 is connected to the worm 35. The drive shaft of the drive motor 31 and the worm 35 are arranged in parallel with the rack 6. The helical teeth on the worm 35 mesh with the rack teeth provided on the rack 6. And refer to Figure 5 The spiral teeth are composed of multiple spiral threads arranged side by side and at equal distances.

[0021] The worm 35 includes a rotating shaft 351 and a worm body 352. The worm body 352 is fixedly connected to the outer side of the rotating shaft 351 and can extend from the housing opening and engage with the side rack 6. Since the rack 6 is relatively wide, the contact surface between the worm 35 and the rack 6 is only one-third under normal conditions. When in use, the relative height between the linear drive mechanism 3 and the rack 6 can be adjusted, thereby adjusting the relative height between the worm 35 and the rack 6, so that the rack 6 can be used separately at different heights. In actual use, the rack 6 can be divided into three layers: upper, middle and lower, and each layer can be used separately, thereby greatly reducing the use cost caused by the wear of the rack 6.

[0022] In addition, the rack 6 is composed of multiple rack bodies 61. Since most of the rack bodies 61 are not used during use, when the rack body 61 on the rear side is completely worn out, the unworn rack body 61 in the same machine can be replaced, thereby reducing the time and material costs of frequent replacement.

[0023] One end of the rotating shaft 351 extends out of the driving mechanism housing 33, and the other end of the rotating shaft 351 passes through the inner partition 331 and extends into the first inner cavity 332. The two ends of the rotating shaft 351 are rotatably connected to the driving mechanism housing 33 through the first stopper 353 and the second stopper 354. The rotating shaft 351 is fixedly connected to the coupling 34 in the first inner cavity 332, and also includes a first connecting bearing 355 and a second connecting bearing 356. The second connecting bearing 356 is arranged between the rotating shaft 351 and the driving mechanism housing 33, and the first connecting bearing 355 is arranged between the rotating shaft 351 and the inner partition 331.

[0024] When the worm 35 is driven to rotate by the driving motor 31, the rack teeth cooperate with the spiral teeth, so that the worm 35 moves linearly along the length direction of the rack 6, so that the connecting seat 4 moves horizontally on the frame 1, thereby adjusting the relative position of the connecting seat 4 on the frame 1 to adapt to the size of the glass to be processed.
