Description

Technical Field

[0001] The utility model relates to the technical field of spreading devices, in particular to a spreading device for machining. Background Art

[0002] Machining is a very important processing method, which is widely used in the manufacturing industry. The key part of machining is the machine tool, which is a machine used to process raw materials. According to different machining methods, it can be divided into cutting, drilling, milling, turning, CNC machining, grinding and other types. When manufacturing thin-walled shell products, due to the low structural strength of the thin-walled shell, it is difficult to clamp it, resulting in difficulty in reliable fixation during grinding, milling and other processing, so the processing is more difficult.

[0003] In the prior art, a Chinese patent with authorization announcement number CN219004637U discloses an internal support tooling, which fixes the blank by means of internal support, and expands the internal support by squeezing the inner cone surface against the outer cone surface, thereby making the internal support deform evenly, so that the blank is evenly stressed, ensuring the reliability of blank processing, and the blank is easy to disassemble and assemble, and the blank can be disassembled and assembled by only loosening and tightening the locking screws.

[0004] The above-mentioned prior art solution has the following defects: the premise for disassembling and assembling the thin shell blank by loosening and tightening the locking screws is that the thin shell blank is a bottomless shell, otherwise the locking screws cannot be loosened and tightened. Therefore, the above solution cannot meet the requirements of the expansion and fixation of the thin shell with a bottom, and the expansion range of the inner support part by squeezing the inner conical surface by the outer conical surface is very limited, so the specifications of the thin shell parts that can be adapted are limited.

[0005] For this reason, a spreading device for machining is proposed. Utility Model Content

[0028] More specifically, the satellite bevel gear rotating assembly 7 meshingly arranged on its surface is driven to rotate by the active bevel gear rotating assembly 6, and then the several radial moving assemblies 8 uniformly distributed in an annular array are driven to work synchronously by the satellite bevel gear rotating assembly 7, and finally several support columns 9 fixedly installed on the surface of the radial moving assembly 8 are radially moved synchronously, so that the supporting space formed by the several support columns 9 distributed in an annular array is adjustable, and thus it can adapt to thin shell blanks of different specifications and prop up their sides, and by arranging the turnover assembly 2 and the pushing assembly 3 relatively to the left and right, the pushing assembly 3 and the support columns 9 are arranged left and right, and the pushing assembly 3 is moved to the side close to the support columns 9, so that the bottom of the thin shell blank can be squeezed, and the thin shell blank with a bottom can be strengthened and fixed, and the loading plate 4 is driven to rotate or stop by the start and stop of the turnover assembly 2, so as to realize the rotation and positioning of the thin shell blank, and facilitate various types of machining operations such as grinding and cutting on the thin shell blank.

[0029] The turnover assembly 2 includes a mounting plate 201, which is fixedly mounted on one side of the top surface of the base 1. A turnover motor 202 is fixedly mounted on the surface of the mounting plate 201 away from the push assembly 3. The output end of the turnover motor 202 is fixedly connected to a main shaft 203, which passes through the surface of the mounting plate 201 and is rotatably arranged. The surface of the main shaft 203 is fixedly connected to the surface of the loading plate 4.

[0030] Specifically, the output end of the rotary motor 202 drives the main shaft 203 to rotate or stop, so that the loading plate 4 fixedly mounted on the surface of the main shaft 203 rotates or stops, thereby controlling the motion state of the loading plate 4, and finally controlling the motion state of the thin shell blank mounted on the surface of the support column 9.

[0031] The pushing assembly 3 includes a limiting slide groove 301, which is opened on the top surface of the base 1, and an electric push rod 302 is fixedly installed on the inner wall of the limiting slide groove 301 close to the surface of the turnover assembly 2, and the telescopic end of the electric push rod 302 is fixedly connected to a moving plate 303, and the moving plate 303 is slidably installed on the inner wall surface of the limiting slide groove 301. The moving plate 303 and the mounting plate 201 are arranged opposite to each other on the left and right, and an extrusion column 304 is fixedly installed on the surface of the moving plate 303 close to the mounting plate 201, and a rotating block 305 is rotatably installed on the surface of one end of the extrusion column 304 close to the mounting plate 201.

[0032] Specifically, the telescopic end of the electric push rod 302 drives the moving plate 303 to move left and right, so that the moving plate 303 drives the extrusion column 304 and the rotating block 305 on its surface to move toward the direction close to the thin shell blank, so that the rotating block 305 squeezes the bottom of the thin shell blank. Since the rotating block 305 is rotatably installed on the surface of the extrusion column 304, under the action of friction, when the loading plate 4 rotates, the support column 9, the thin shell blank and the rotating block 305 rotate synchronously; when the loading plate 4 is stationary, the support column 9, the thin shell blank and the rotating block 305 are stationary synchronously.

[0033] The active bevel gear rotating assembly 6 includes a driving motor 601, which is fixedly installed inside the loading plate 4. The output end of the driving motor 601 is fixedly connected to a driving shaft 602. The driving shaft 602 is rotatably installed on the left and right sides of the inner wall of the gear cavity 5. A main bevel gear 603 is fixedly sleeved on the surface of the active shaft 602. The satellite bevel gear rotating assembly 7 is meshed and arranged on the surface of the main bevel gear 603.

[0034] Specifically, the output end of the driving motor 601 drives the active rotating shaft 602 and the main bevel gear 603 to rotate, thereby causing the satellite bevel gear rotating assembly 7 meshing with the surface of the main bevel gear 603 to rotate.

[0035] The satellite bevel gear rotation assembly 7 includes a mounting cover 701, a slave bevel gear 702 and a driven shaft 703. The mounting cover 701 is fixedly mounted on a side surface of the inner wall of the gear cavity 5 away from the main bevel gear 603. A gap is provided between the mounting cover 701 and the main bevel gear 603. The driving shaft 602 is rotationally connected to the side wall of the mounting cover 701. The slave bevel gears 702 are meshed and arranged on the surface of the main bevel gear 603. The number of the slave bevel gears 702 is several and is evenly distributed in an annular array. The driven shaft 703 is fixedly inserted on the surface of the slave bevel gear 702 and is rotationally mounted between the side wall of the mounting cover 701 and the side wall of the gear cavity 5. The driven shaft 703 is fixedly connected to the local structure of the radial moving assembly 8.

[0036] Specifically, a gap is provided between the mounting cover 701 and the main bevel gear 603 to ensure that the mounting cover 701 does not interfere with the main bevel gear 603 when it rotates. When the main bevel gear 603 rotates, several slave bevel gears 702 meshingly arranged on its surface rotate synchronously, thereby driving the driven shaft 703 fixedly inserted on the surface of the slave bevel gear 702 to rotate synchronously. By rotatably installing the driven shaft 703 between the side wall of the mounting cover 701 and the side wall of the gear cavity 5, the rotation of the driven shaft 703 is more stable and reliable, and then the driven shaft 703 can stably drive several radial moving components 8 to work synchronously.

[0037] The radial moving component 8 includes a radial slide groove 801, which is opened on one side surface of the loading plate 4 close to the pushing component 3. The number of radial slide grooves 801 is the same as the number of the helical gears 702 and is evenly distributed in an annular array. A threaded rod 802 is radially rotatably installed on the inner wall surface of the radial slide groove 801. One end of the threaded rod 802 close to the gear cavity 5 is fixedly connected to the end of the driven shaft 703. A slider 803 is threadedly installed on the surface of the threaded rod 802. The slider 803 is slidably installed on the inner wall surface of the radial slide groove 801, and the support column 9 is fixedly installed on the surface of the slider 803.

[0038] Specifically, when several driven shafts 703 rotate synchronously, the threaded rod 802 fixedly connected to the driven shaft 703 rotates synchronously. When the threaded rod 802 rotates, the slider 803 threadedly installed on its surface and slidably installed on the inner wall surface of the radial groove 801 will slide along the inner wall surface of the radial groove 801. Since the radial groove 801 is radially arranged, the slider 803 will slide radially. The synchronous radial sliding of several sliders 803 distributed in an annular array will drive the synchronous radial sliding of several support columns 9 fixedly installed on the surface of the slider 803, so that the support space formed by the several support columns 9 distributed in an annular array can be quickly adjusted, so that thin shell blanks of different specifications can be supported and opened for machining.

[0039] In summary: the satellite bevel gear rotating assembly 7 meshingly arranged on its surface is driven to rotate by the active bevel gear rotating assembly 6, and then the several radial moving assemblies 8 evenly distributed in an annular array are driven to work synchronously by the satellite bevel gear rotating assembly 7, and finally several support columns 9 fixedly installed on the surface of the radial moving assembly 8 are radially moved synchronously, so that the supporting space formed by the several support columns 9 distributed in an annular array is adjustable, and thus can adapt to thin shell blanks of different specifications and prop up their sides; by arranging the turnover assembly 2 and the pushing assembly 3 relatively to the left and right, the pushing assembly 3 and the support columns 9 are arranged left and right, and by moving the pushing assembly 3 to the side close to the support columns 9, the bottom of the thin shell blank can be squeezed, so that the thin shell blank with a bottom can be strengthened and fixed, and the loading plate 4 is driven to rotate or stop by the start and stop of the turnover assembly 2, so as to realize the rotation and positioning of the thin shell blank, and facilitate various types of machining operations such as grinding and cutting on the thin shell blank.
