Description

Technical Field

[0001] This utility model relates to the field of base positioning devices, and in particular to a base positioning device for chandelier processing. Background Technology

[0002] A chandelier is a high-end decorative lighting fixture suspended from the ceiling. Whether suspended by wires or metal rods, a chandelier should not be hung too low, as this can obstruct normal vision or cause glare. For example, in a dining room, the ideal height for a chandelier is to create a pool of light around the table without obstructing the view of people sitting at the table. Modern chandeliers are equipped with springs or height adjusters to suit different ceiling heights and needs.

[0003] When processing the base of a chandelier, it needs to be clamped and positioned first. Chandelier bases are mostly circular with a hole in the center. The hole is mainly for the wires to pass through to supply power to the chandelier. Existing chandelier base positioning devices first place the base on the processing table and clamp it using multiple movable clamping ends. When the base is placed in a different position, it may move during clamping. Therefore, positioning rods are usually installed on the processing table. However, positioning rods are relatively fixed, and when the hole in the chandelier base is large, it is easy for the base to be placed in an inaccurate position.

[0004] Therefore, it is necessary to provide a new base positioning device for chandelier manufacturing to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a base positioning device for chandelier processing.

[0006] The chandelier base positioning device provided by this utility model includes a processing table. A clamping device is installed at the bottom of the processing table, and the clamping device is provided with multiple clamping ends. The multiple clamping ends are arranged above the processing table through through holes. A placement cylinder is installed at the center of the multiple clamping ends on the top of the processing table. Multiple elastic telescopic devices are inserted through the side wall of the placement cylinder. A positioning block is installed at the end of the elastic telescopic device. The end of the positioning block away from the placement cylinder is an upward inclined surface. A driving device is installed at the top of the placement cylinder. The driving device can adjust the position of the multiple elastic telescopic devices simultaneously.

[0007] Preferably, the clamping device includes a driving component and multiple transmission components, the driving component is mounted on the bottom of the processing table, and the multiple transmission components are distributed around the driving component.

[0008] Preferably, the driving component includes a bracket, a motor, and a driving bevel gear. The bracket is installed on the bottom of the processing table, the motor is mounted on the bracket, and the output end of the motor is fixedly connected to the driving bevel gear.

[0009] Preferably, the transmission component includes a bearing plate, a threaded rod, and a driven bevel gear. The bearing plate is fixed to the bottom of the machining table, the threaded rod is rotatably connected to the bearing plate, and a clamping plate is threaded onto the threaded rod. The clamping plate is movably inserted into the through hole of the machining table, and the size of the clamping plate is adapted to the size of the through hole of the machining table. The driven bevel gear is fixed to the end of the threaded rod, and the driving bevel gear meshes with the driven bevel gear.

[0010] Preferably, the elastic telescopic device includes an elastic element, a sleeve, and a first spring. The sleeve is movably inserted into a through hole in the side wall of the placement cylinder. The positioning block is movably disposed inside the sleeve. The two ends of the first spring are respectively fixedly connected to the end of the positioning block and the bottom wall of the inner cavity of the sleeve. The elastic element is connected to the inner wall of the placement cylinder and the sleeve.

[0011] Preferably, the elastic element includes a side plate and a second spring, the side plate being fixedly installed on the sleeve, and the two ends of the second spring being fixed to the side plate and the inner wall of the sleeve, respectively.

[0012] Preferably, the driving device includes a rotating column, a pressing column, and a guide rod. The rotating column is threaded to the top wall of the placement cylinder, and the rotating column is rotatably connected to the pressing column. The guide rod is fixedly connected to the pressing column and is inserted into a through hole in the top wall of the placement cylinder. The bottom end of the pressing column is in the shape of an inverted frustum, and one end of the sleeve is an inclined surface adapted to the frustum-shaped structure of the pressing column.

[0013] Compared with related technologies, the chandelier base positioning device provided by this utility model has the following advantages: When using this device, the position of the positioning block is adjusted according to the hole in the center of the processed base. The rotating column is rotated, and the pressing column rises or falls under the action of the guide rod. When the pressing column falls, the bottom end of the pressing column presses against the end of the sleeve, causing the sleeve to move the positioning block to the outside of the placement cylinder. When the pressing column rises, the sleeve moves the positioning block to the inside of the placement cylinder under the action of the compressed second spring. After adjustment, the base is placed. When the base presses against the inclined surface of the positioning block, the positioning block moves to the inside of the sleeve, and the first spring is compressed, achieving the pre-positioning of the base. This device can meet the positioning work of chandelier bases of more than one size, improving flexibility. Attached Figure Description

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0017] Please refer to the following: Figures 1-4 ,in, Figure 1 A schematic diagram of the structure of the chandelier base positioning device provided by this utility model; Figure 2 for Figure 1 A bottom-view structural diagram of the structure shown; Figure 3 for Figure 1 A partial cross-sectional structural diagram of the structure shown. Figure 4 for Figure 1 The diagram shows the structure inside the placement cylinder.

[0018] In the specific implementation process, such as Figures 1-4 As shown, the machine includes a processing table 1. A clamping device is installed at the bottom of the processing table 1. The clamping device has multiple clamping ends. The multiple clamping ends are located above the processing table 1 through through holes. A placement cylinder 2 is installed at the center of the multiple clamping ends on the top of the processing table 1. Multiple elastic telescopic devices are inserted through the side wall of the placement cylinder 2. A positioning block 3 is installed at the end of the elastic telescopic device. The end of the positioning block 3 away from the placement cylinder 2 is an upward inclined surface. A driving device is installed on the top of the placement cylinder 2. The driving device can adjust the position of the multiple elastic telescopic devices at the same time. The clamping device includes a driving component and multiple transmission components. The driving component is installed at the bottom of the processing table 1, and the multiple transmission components are distributed around the driving component. The driving component includes a bracket 4, a motor 5, and a driving bevel gear 6. The bracket 4 is installed at the bottom of the processing table 1, and the motor 5 is installed on the bracket 4. The output end of the motor 5 is fixedly connected to the driving bevel gear 6. The transmission components include a bearing plate 7, a threaded rod 8, and a driven bevel gear 9. The bearing plate 7 is fixed at the bottom of the processing table 1, and the threaded rod 8 is rotatably connected to the bearing plate 7. A clamping plate 10 is threadedly connected to the threaded rod 8. The clamping plate 10 is movably inserted into the through hole of the processing table 1, and the size of the clamping plate 10 is adapted to the size of the through hole of the processing table 1. The driven bevel gear 9 is fixed to the end of the threaded rod 8. The driving bevel gear 6 meshes with the driven bevel gear 9. The motor 5 drives the driving bevel gear 6 to rotate, which in turn causes the multiple driven bevel gears 9 to drive the threaded rod 8 to rotate. The multiple clamping plates 10 all move towards the placement cylinder 2 to clamp the base. The elastic telescopic device includes an elastic element, a sleeve 11, and a first spring 12. The sleeve 11 is movably inserted into the through hole in the side wall of the placement cylinder 2. The positioning block 3 is movably disposed in the sleeve 11. The two ends of the first spring 12 are respectively fixedly connected to the end of the positioning block 3 and the bottom wall of the inner cavity of the sleeve 11. The elastic element is connected to the inner wall of the placement cylinder 2 and the sleeve 11. The elastic element includes a side plate 14 and a second spring 15. The side plate 14 is fixedly installed on the sleeve 11. The two ends of the second spring 15 are respectively fixed to the side plate 14 and the inner wall of the placement cylinder 2. When the pressing column 17 descends, the bottom end of the pressing column 17 presses against the end of the sleeve 11, causing the sleeve 11 to drive the positioning block 3 to move outward from the placement cylinder 2. When the pressing column 17 rises, under the action of the compressed second spring 15, the sleeve 11 drives the positioning block 3 to move inward from the placement cylinder 2, thereby realizing the adjustment of the position of the positioning block 3. The driving device includes a rotating column 16, a pressing column 17, and a guide rod 13. The rotating column 16 is threaded to the top wall of the placement cylinder 2. The rotating column 16 and the pressing column 17 are rotatably connected. The guide rod 13 is fixedly connected to the pressing column 17 and is inserted into a through hole in the top wall of the placement cylinder 2. The bottom end of the pressing column 17 is in the shape of an inverted frustum. One end of the sleeve 11 is an inclined surface that adapts to the frustum-shaped structure of the pressing column 17. When the rotating column 16 is rotated, the pressing column 17 rises or falls under the action of the guide rod 13.

[0019] The working principle of this utility model is as follows: When using the device, the position of the positioning block 3 is adjusted according to the hole in the center of the processed base. The rotating column 16 is rotated, and the pressing column 17 rises or falls under the action of the guide rod 13. When the pressing column 17 falls, the bottom end of the pressing column 17 presses the end of the sleeve 11, causing the sleeve 11 to drive the positioning block 3 to move outward of the placement cylinder 2. When the pressing column 17 rises, under the action of the compressed second spring 15, the sleeve 11 drives the positioning block 3 to move inward of the placement cylinder 2. After the adjustment is completed, the base is placed. When the base presses against the inclined surface of the positioning block 3, the positioning block 3 moves inward of the sleeve 11, and the first spring 12 is compressed, realizing the pre-positioning of the base. The motor 5 drives the drive bevel gear 6 to rotate, which in turn causes multiple driven bevel gears 9 to drive the threaded rod 8 to rotate. Multiple clamping plates 10 move towards the placement cylinder 2 to clamp the base.

[0020] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.
