Description

Technical Field

[0001] The utility model relates to the technical field of sawing machines, in particular to a rotary multi-station sawing machine. Background Art

[0002] A multi-station sawing machine is a sawing machine with multiple processing positions and workpiece clamping devices. It can cut multiple workpieces simultaneously or sequentially. This equipment is usually equipped with an advanced control system and automatic feeding device, which can realize automated and high-precision cutting operations.

[0003] After searching, the patent with announcement number CN219746524U discloses a multi-station circular sawing band saw machine. Although the multi-station circular sawing band saw machine solves the problem that the circular sawing band saw machine can only saw at one station with a fixed spatial position, cannot load and unload at the same time, and has low efficiency, during use, only the rotating platform rotates and the station cannot rotate, resulting in the saw blade being able to only saw the partial outer wall of the circular workpiece as the rotating platform rotates. It is necessary to frequently adjust the placement position of the circular workpiece until the outer wall is completely sawed and formed.

[0004] In view of the above problems, the present utility model document proposes a rotary multi-station sawing machine. Utility Model Content

[0005] The utility model provides a rotary multi-station sawing machine, which solves the problem in the prior art that during use, only the rotating platform rotates and the stations cannot rotate, resulting in the sawing knife being able to saw only part of the outer wall of the annular workpiece as the rotating platform rotates, and the placement position of the annular workpiece needs to be frequently adjusted until the outer wall is completely sawed and formed.

[0006] The utility model provides the following technical solutions:

[0007] A rotary multi-station sawing machine, comprising:

[0008] A sawing machine body, wherein a vertically arranged saw blade is mounted on a tool holder of the sawing machine body, a rotating table is rotatably mounted on the sawing machine body, four bearing seats for carrying annular workpieces are rotatably mounted on the surface of the rotating table in an annular array, and an extension plate is fixedly mounted on one side of the tool holder on the sawing machine body;

[0009] The telescopic rotating component is arranged on the extension plate and is used for driving the butted annular workpiece to rotate so that the saw blade can cut its surface.

[0010] In one possible design, the rotating shaft of the rotating table passes through the inner wall of the sawing machine body and is fixedly provided with a first bevel gear, a first drive motor is fixedly installed on the side wall of the sawing machine body, the output shaft of the first drive motor passes through the inner wall of the sawing machine body and is fixedly provided with a second bevel gear, and the second bevel gear is engaged with the first bevel gear.

[0011] In one possible design, the telescopic rotating assembly includes a telescopic rod rotatably mounted on the bottom of an extension plate, a second drive motor for driving the telescopic rod to rotate is fixedly mounted on the top of the extension plate, and a pressure plate is fixedly provided at the bottom end of the telescopic rod to contact the top of the annular workpiece.

[0012] In one possible design, a hydraulic cylinder is fixedly installed on the top of the extension plate, the output end of the hydraulic cylinder passes through the bottom of the extension plate and is fixedly provided with a lifting plate, a rotating bearing is embedded and fixedly installed on the lifting plate, and the outer wall of the movable rod of the telescopic rod is welded to the inner ring of the rotating bearing.

[0013] In a possible design, a limiting ring is fixedly provided on the top of the bearing seat for fitting and fixing the inner wall of the annular workpiece.

[0014] In a possible design, a plurality of rubber ridges for increasing friction are fixedly provided on the bottom of the pressure plate in an annular array.

[0015] It should be understood that the above general description and the following detailed description are merely illustrative and do not limit the present invention.

[0016] The working principle and usage process of this technical solution are as follows:

[0017] When in use, the annular workpiece to be cut is placed in the bearing seat on the rotary table, and the inner wall of the annular workpiece is fixed by a limiting ring to ensure that the workpiece is stable and motionless. After starting the first drive motor, its output shaft drives the second bevel gear to rotate. Since the second bevel gear is meshed with the first bevel gear, the rotary table will rotate accordingly, thereby changing the positions of the four annular workpieces. When the annular workpiece reaches a suitable cutting position, the rotary table stops rotating. Then, according to the height of the workpiece, the height of the lifting plate is adjusted by the hydraulic cylinder so that the pressure plate at the bottom end of the telescopic rod can just contact the top of the annular workpiece. At the same time, the second drive motor is started, and its output shaft drives the pressure plate to rotate through the telescopic rod. Since the pressure plate contacts the top of the annular workpiece, the annular workpiece will also rotate under the drive of the pressure plate. Then the saw blade is started for cutting. The saw blade will cut the surface of the annular workpiece along the vertical direction. During the cutting process, the cutting speed, feed rate and other parameters of the saw blade can be adjusted as needed to ensure cutting quality and efficiency.

[0018] When the cutting of an annular workpiece is completed, the hydraulic cylinder drives the pressure plate to reset, and the first drive motor will continue to drive the rotary table to rotate, moving the next annular workpiece to be cut to the cutting position of the saw blade, and repeating the above steps until all annular workpieces are cut.

[0019] The utility model has the following beneficial effects:

[0020] The utility model realizes multi-station cutting of annular workpieces through the cooperation of the rotary table and the telescopic rotary assembly, greatly improving the cutting efficiency. At the same time, the stability of the equipment and the cutting quality are further improved through the arrangement of components such as the hydraulic cylinder, the limit ring and the rubber convex strip.

[0030] Example 1

[0031] Please refer to Figure 1-4 , a rotary multi-station sawing machine, which is used in the field of sawing machines, including:

[0032] The sawing machine body 1 serves as the supporting structure of the entire equipment. A saw blade 2 is vertically installed on the tool holder for cutting the workpiece. A rotary table 3 is rotatably installed on the sawing machine body 1. Four bearing seats 7 are rotatably installed on the surface of the rotary table 3 in a circular array. Each bearing seat 7 is used to carry an annular workpiece. A limiting ring 8 is fixedly set on the top of each bearing seat 7. The inner wall of the limiting ring 8 is used to fit and fix the annular workpiece, thereby increasing the stability of the annular workpiece on the bearing seat 7 and preventing it from shaking or shifting during the cutting process. In addition, an extension plate 9 is fixedly set on one side of the tool holder of the sawing machine body 1.

[0033] In order to realize the rotation of the turntable 3, the rotating shaft of the turntable 3 passes through the inner wall of the sawing machine body 1 and is fixedly provided with a first bevel gear 4. At the same time, a first drive motor 5 is fixedly installed on the side wall of the sawing machine body 1, and its output shaft also passes through the inner wall of the sawing machine body 1 and is fixedly provided with a second bevel gear 6. The second bevel gear 6 is engaged with the first bevel gear 4, thereby realizing the rotation of the turntable 3 by the drive of the first drive motor 5.

[0034] In order to realize the rotation of the butted annular workpiece so that the saw blade 2 can cut its surface, a telescopic rotation assembly is provided on the extension plate 9, which includes a telescopic rod 10 rotatably mounted on the bottom of the extension plate 9, and a second drive motor 11 for driving the telescopic rod 10 to rotate. A pressure plate 15 is fixedly provided at the bottom end of the telescopic rod 10, and the pressure plate 15 can contact the top of the annular workpiece and is driven by the second drive motor 11 to rotate;

[0035] A hydraulic cylinder 14 is fixedly installed on the top of the extension plate 9, and its output end passes through the bottom of the extension plate 9 and is fixedly provided with a lifting plate 13. On the lifting plate 13, a rotating bearing 12 is embedded and fixedly installed. The outer wall of the movable rod of the telescopic rod 10 is welded to the inner ring of the rotating bearing 12. In this way, the telescopic rod 10 and the pressure plate 15 at the bottom end can be raised and lowered by the drive of the hydraulic cylinder 14, so as to more flexibly adapt to annular workpieces of different heights.

[0036] Example 2

[0037] Improvements based on Example 1:

[0038] Please refer to Figure 5 In order to increase the friction between the pressure plate 15 and the annular workpiece and prevent slipping during rotation, this embodiment also has a plurality of rubber ridges 16 fixedly arranged in an annular array at the bottom of the pressure plate 15. These rubber ridges 16 not only increase the friction but also provide a certain degree of protection for the surface of the annular workpiece.

[0039] However, as is well known to those skilled in the art, the working principles and wiring methods of the sawing machine body 1, the first drive motor 5, the second drive motor 11 and the hydraulic cylinder 14 are commonplace, and are all conventional means or common knowledge, so they will not be elaborated here.
