Description

Technical Field

[0001] The invention relates to the technical field of band sawing machines, in particular to a servo feed sawing precision spindle motor sawing machine with a chip suction structure. Background Art

[0002] A sawing machine is a machine tool that uses saw belts, saw blades and other tools to cut the materials to be cut. Existing sawing machines include a workbench and a cutting device, wherein the workbench is used to place the materials to be cut, such as steel plates, steel pipes, etc., and the cutting device cuts the materials placed on the workbench. Among them, the cutting device using a saw belt as a tool is a widely used cutting device, which is mainly used to cut materials with a long length, so that the cutting can be completed by using a saw belt with a sufficiently long length to go down to a specified depth.

[0003] In the actual use of traditional horizontal band saws, a large amount of sawing debris will be generated. Although it will accumulate in the debris trough with the flow of cutting fluid, some of the debris will be scattered on the cutting table under the impact of the cutting fluid. In order to ensure that the debris does not affect the sawing of the saw band and reduce the debris adhering to the surface of the workpiece and affecting the surface quality of the workpiece, it is necessary to clean the debris in the cutting table and the debris trough from time to time. Manual cleaning is often used, which is inconvenient to clean. In addition, the sawing machine needs to be completely stopped during the cleaning process, which not only increases the cumbersomeness of chip cleaning, but also reduces the sawing efficiency of the band saw.

[0004] In view of the above technical defects, a solution is now proposed. Summary of the invention

[0040] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Embodiment 1: In view of the problem in the prior art that the chip cleaning is performed manually from time to time, which not only increases the complexity of chip cleaning but also reduces the sawing efficiency of the band saw, the following solution can be used to solve the problem:

[0042] See also Figure 1-Figure 7As shown, the servo-feed saw precision spindle motor sawing machine with a chip suction structure in this embodiment includes a saw frame 1, one side of the saw frame 1 is symmetrically rotatably connected with a rotating shaft 11, a saw wheel 12 is fixedly connected to the rotating shaft 11, a saw band 13 is sleeved between the saw wheels 12, and a spindle drive motor 14 for driving the corresponding rotating shaft 11 to rotate is bolted on the saw frame 1. The high-precision and high-stability spindle drive motor 14 drives the corresponding saw wheel 12 to rotate, and cooperates with another saw wheel 12 to drive the saw band 13 to rotate, which can ensure that the saw band 13 maintains stable cutting performance when rotating at high speed, thereby improving the sawing accuracy and efficiency, and two sets of lifting seats 15 are symmetrically welded on the saw frame 1;

[0043] A guide assembly 2 is provided on the lifting seat 15. The guide assembly 2 includes a guide frame 21 fixedly connected to the lifting seat 15, which is used to twist and deform the saw belt 13 below the saw wheel 12, forcing the saw teeth of the saw belt 13 to always be stably oriented downward during the rotation of the saw belt 13, thereby improving the sawing effect. A connecting plate 3 is fixedly connected between the tops of the guide frames 21, and auxiliary frames 1 31 and 2 32 with the same structure are symmetrically installed on both sides of the bottom of the connecting plate 3. A chip suction assembly 4 is provided on the auxiliary frame 1 31. The auxiliary frame 1 31 and the auxiliary frame 2 32 are used for the installation of the chip suction assembly 4, which effectively collects the debris generated by sawing, and can also support the saw belt 13 near the workpiece at a close distance, maintain stability during the sawing process, and prevent the sawing effect and the life of the saw belt 13 from being reduced due to the shaking of the saw belt 13.

[0044] The chip suction assembly 4 includes a collecting shell 41 fixedly connected to the bottom of the auxiliary frame 31 for collecting chips, and a chip guide filter hopper 42 is fixedly connected to one side of the collecting shell 41 for guiding the chips into the collecting shell 41 and filtering the cutting liquid in the chips. The auxiliary frame 1 31 and the auxiliary frame 2 32 move relative to or apart so that the two are located in a clamping state on both sides of the workpiece to be cut, so that one side of the chip guide filter hopper 42 contacts the outer wall of the workpiece to ensure effective collection of the chips. A chip conveyor barrel 43 adapted to the collecting shell 41 is rotatably installed inside the collecting shell 41, and a chip suction cover 44 matching the chip conveyor barrel 43 is fixedly connected to the side of the collecting shell 41 away from the chip guide filter hopper 42, and a chip suction pipe 45 is fixedly connected to the chip suction cover 44, which is used to discharge the collected chips in the collecting shell 41 through the chip suction cover 44 and the chip suction pipe 45.

[0045] A base 16 is provided below the saw frame 1, and a vertical guide rod 17 slidably connected to the corresponding lifting seat 15 is welded on the top of the base 16 to increase the installation and lifting stability of the saw frame 1, and a fixing plate 18 is fixedly connected between the tops of the vertical guide rods 17, and a lifting screw 19 threadedly connected to the corresponding lifting seat 15 is rotatably connected between the fixing plate 18 and the base 16, and a servo lifting motor 110 for driving the corresponding lifting screw 19 to rotate is installed on the top bolt of the fixing plate 18;

[0046] First, the saw band 13 is driven to rotate by the spindle drive motor 14, and then the corresponding lifting screw 19 is driven to rotate by the servo lifting motor 110, and the saw frame 1 is driven to descend with the corresponding lifting seat 15. With the cooperation of the guide frame 21 and the auxiliary frame, the reverse force of the downward movement of the saw band 13 is offset, so as to perform the sawing operation of the workpiece. The sawing action of the saw band 13 is precisely controlled by the servo system through the rotation angle and speed of the servo lifting motor 110, so as to realize high-precision feeding action of the saw band 13. Compared with the traditional hydraulic feeding method, it can realize more precise control of the sawing feed speed according to the shape of the workpiece, which helps to increase the service life of the saw band 13.

[0047] The top of the base 16 is located between the vertical guide rods 17 and is fixedly connected to a cutting table 5 for placing the workpiece. When the saw frame 1 descends for sawing, the interference of the base 16 with its movement is effectively avoided. The top of the cutting table 5 is located directly below the guide frame 21 and is provided with a liquid collecting tank 51. Liquid guide buckets 52 are fixedly connected to the liquid collecting tank 51 on both sides of the cutting table 5 for collecting and discharging the cutting fluid.

[0048] A mounting plate 53 is symmetrically fixedly connected to one side of the top of the cutting table 5 away from the liquid collecting tank 51, a clamping hydraulic cylinder 54 is bolted to the mounting plate 53, and the piston rod head of the clamping hydraulic cylinder 54 is fixedly connected to a clamping plate 55. The workpiece to be cut is placed on the cutting table 5, and the piston rods of the clamping hydraulic cylinders 54 on both sides are extended to drive the corresponding clamping plates 55 to move relative to each other, thereby realizing the center clamping of the workpiece.

[0049] A clamping groove 1 is provided at the bottom of the guide frame 21 for clamping the saw band 13 therein and protecting the saw band 13 at this position. The inner walls of both sides of the clamping groove 1 are rotatably connected with clamping wheels 12 for clamping the saw band 13 to prevent the saw band 13 from shaking during sawing, thereby reducing the sawing effect and the life of the saw band 13. An abutment wheel 23 is rotatably connected to the top of the clamping groove 1 for supporting the back of the saw band 13 and offsetting the reverse force of the downward movement of the saw band 13 to achieve normal sawing operation of the workpiece. A deflection wheel 24 is symmetrically rotatably connected to one side of the guide frame 21 away from the connecting plate 3. The deflection wheels 24 on both sides are used to clamp the saw band 13 to achieve the twisting of the saw band 13, and cooperate with the clamping wheel 22 to ensure that the saw teeth of the saw band 13 are always and stably facing downward during the rotation of the saw band 13.

[0050] Chip guard plates 25 are symmetrically arranged between the guide frames 21 and on both sides of the connecting plate 3, and trapezoidal blocks 26 are symmetrically fixedly connected to the opposite side of the chip guard plates 25. Trapezoidal grooves 27 slidingly connected to the corresponding trapezoidal blocks 26 are provided on the guide frames 21. When the servo lifting motor 110 drives the saw frame 1 to descend, the bottoms of the two groups of chip guard plates 25 between the guide frames 21 first contact the workpiece, and as the saw frame 1 continues to descend, the chip guard plates 25 move upward relative to the guide frames 21, effectively preventing the cutting fluid from splashing everywhere during the spraying process. At the same time, it can further ensure the protection effect of the saw belt 13 during the sawing process, and when the guide frame 21 moves upward, the chip guard plates 25 move upward relative to the guide frame 21 and reset under the action of their own gravity.

[0051] The bottom of the connecting plate 3 is symmetrically provided with T-shaped slots 33, and the tops of the auxiliary frame 1 31 and the auxiliary frame 2 32 are fixedly connected with T-shaped blocks 34 that are slidably connected to the corresponding T-shaped slots 33. The connecting plate 3 is bolted with an adjusting motor 35, and the output shaft of the adjusting motor 35 is fixedly connected with a transmission gear 36. The opposite sides of the auxiliary frame 1 31 and the auxiliary frame 2 32 are fixedly connected with toothed plates 37 that mesh with the transmission gear 36.

[0052] The adjusting motor 35 drives the transmission gear 36 to rotate, and the transmission gear 36 drives the auxiliary frame 1 31 and the auxiliary frame 2 32 to move relative to or away from each other with the help of the tooth plates 37 meshing on both sides, thereby achieving a close-range support for the saw belt 13 near the workpiece according to the size of the workpiece, maintaining stability during the sawing process, and as the saw frame 1 continues to descend and cut, the adjusting motor 35 is continuously rotated forward and reverse according to the shape of the clamping side of the workpiece, forcing one side of the chip guide filter 42 to always be in contact with the outer wall of the workpiece, further ensuring the effective collection of debris. The bottom of the connecting plate 3 is located on both sides of the transmission gear 36 and is symmetrically fixedly connected with an L-shaped plate that is slidably connected to the corresponding tooth plates 37, which is used to ensure stable meshing of the tooth plates 37 with the transmission gear 36.

[0053] A clamping groove 2 is provided on both the auxiliary frame 1 31 and the auxiliary frame 2 32 for clamping the saw band 13 therein and protecting the saw band 13 on both sides of the workpiece. A clamping wheel 2 38 is rotatably connected to the inner walls on both sides of the clamping groove 2 for secondary clamping of the saw band 13, thereby further preventing the saw band 13 from shaking during sawing and reducing the sawing effect. An abutment wheel 2 39 is rotatably connected to the top of the clamping groove 2 for secondary support of the back of the saw band 13 near the workpiece, thereby further offsetting the reverse force of the downward movement of the saw band 13 and improving the service life of the saw band 13. An opening portion is provided on one side of the clamping groove 2 on the auxiliary frame, and a fixing seat is bolted to the opening portion. The clamping wheel 2 38 on one side of the clamping groove 2 is rotatably installed on the fixing seat, thereby realizing the installation and replacement of the saw band 13.

[0054] A liquid outlet pipe 310 is fixedly connected to the top of one side of the auxiliary frame 2 32 close to the auxiliary frame 1 31. The liquid outlet pipe 310 is connected to the external connecting pipe and injects cutting fluid into it. The bottom of the liquid outlet pipe 310 is equidistantly provided with a plurality of obliquely arranged liquid outlet holes 311 along its length direction. The cutting fluid sprayed from the liquid outlet holes 311 is sprayed in the direction of the auxiliary frame 1 31, i.e., the direction of rotation of the saw belt 13, and is sprayed onto the surface of the workpiece below the saw belt 13 in cooperation with the anti-splashing blocking of the chip guard plates 25 on both sides. The saw belt 13 rotates and contacts the workpiece for cutting. During the cutting process, the generated debris moves toward the collecting shell 41 under the impact of the oblique spraying of the cutting fluid, the rotation of the saw belt 13 and the blocking of the chip guard plates 25 on both sides, and enters the collecting shell 41 through the chip guide filter 42 for effective collection.

[0055] A limiting tube 312 is fixedly connected to the auxiliary frame 1 31 and is slidably connected to the liquid outlet pipe 310, and one end of the limiting tube 312 is a closed end. The auxiliary frame 1 31 and the auxiliary frame 2 32 move relative to or apart from each other, and the length of the liquid outlet pipe 310 in the limiting tube 312 is adjusted to partially block the liquid outlet hole 311, thereby automatically adjusting the spraying length of the chip liquid according to the cutting length to improve the lubrication and cooling effect of the longer cutting groove during the sawing process.

[0056] Embodiment 2: The problem that the debris continues to accumulate in the collection shell with a small space and the debris cannot be collected continuously can be solved by the following solution:

[0057] See also Figure 7-10 As shown, the chip suction assembly 4 in this embodiment includes a collecting shell 41 fixedly connected to the bottom of the auxiliary frame 31, and a chip guide filter bucket 42 is fixedly connected to one side of the collecting shell 41, which is used to guide the debris into the collecting shell 41 and filter the cutting liquid in the debris. A chip conveyor cylinder 43 adapted to the collecting shell 41 is rotatably installed inside the collecting shell 41, which is used to convey the debris entering the collecting shell 41 to the chip suction cover 44, so as to avoid the continuous accumulation of debris inside the collecting shell 41 with a smaller space. A chip suction cover 44 matching the chip conveyor cylinder 43 is fixedly connected to the side of the collecting shell 41 away from the chip guide filter bucket 42, and a chip suction pipe 45 is fixedly connected to the chip suction cover 44.

[0058] A plurality of chip collecting filter covers 46 are equidistantly fixedly connected to the annular outer wall of the chip conveying barrel 43. The chip conveying barrel 43 rotates to drive the plurality of chip collecting filter covers 46 to rotate, thereby achieving the effect of continuous chip conveying. A rotating rod 47 is rotatably connected to the inside of the collecting shell 41, and a driving gear 48 is symmetrically fixedly connected to the rotating rod 47. An inner gear ring 49 is fixedly connected to the outer side of the corresponding driving gear 48 on the chip conveying barrel 43. Three sets of planetary gears 410 meshing with the corresponding inner gear ring 49 and the driving gear 48 are rotatably connected to the inner side wall of the collecting shell 41. A chip conveying motor 411 for driving the rotating rod 47 to rotate is bolted to the outer side wall of the collecting shell 41.

[0059] After the debris enters the collection shell 41 through the chip guide filter hopper 42, it falls into the corresponding chip collection filter cover 46 on the chip conveyor barrel 43. The chip conveyor motor 411 drives the rotating rod 47 to rotate, and with the cooperation of the driving gear 48, the planetary gear 410 and the inner gear ring 49, drives the chip conveyor barrel 43 to rotate in the opposite direction, forcing multiple chip collection filter covers 46 to rotate, collect the debris one by one, and then transport the collected debris to the chip suction cover 44, and the debris is extracted and collected centrally through the external chip suction device and the chip suction pipe 45, so as to avoid the problem of continuous accumulation of debris in the collection shell 41 with a smaller space and the inability to collect the debris continuously.

[0060] The rotating rod 47 is fixedly connected with an elastic plate 412. During the rotation of the rotating rod 47, the plurality of elastic plates 412 are synchronously driven to rotate. On the one hand, the chip collecting filter cover 46 in the conveying process is knocked to achieve the knocking separation of a small amount of chip liquid contained in the chips, thereby avoiding the problem that the chips are adsorbed in the chip collecting filter cover 46 and the chip suction cover 44 due to a small amount of chip liquid, and thus being difficult to discharge. On the other hand, the chip collecting filter cover 46 is knocked during the chip removal process to improve the efficiency of chip discharge, and to assist in strengthening the effect of the chip suction pipe 45 on the extraction and discharge of chips.

[0061] A baffle plate 413 is fixedly connected to the rotating rod 47 and is rotatably connected to the corresponding inner gear ring 49 to prevent small debris from being filtered through the chip guide filter bucket 42 and the chip collection filter cover 46 into the chip conveying cylinder 43, and then contacting the driving gear 48, the planetary gear 410 and the inner gear ring 49 to cause rotation interference problems. A drainage groove 414 is opened through the bottom of the collection shell 41, and the cutting fluid entering the collection shell 41 is discharged through the chip guide filter bucket 42, the chip collection filter cover 46 and the drainage groove 414.

[0064] S2: The adjusting motor 35 drives the transmission gear 36 to rotate, and the transmission gear 36 drives the auxiliary frame 1 31 and the auxiliary frame 2 32 to move relative to or away from each other with the help of the toothed plates 37 meshing on both sides, so that the two are located at the positions of clamping the two sides of the workpiece to be cut. At the same time, one side of the chip guide filter 42 on the collecting shell 41 at the bottom of the auxiliary frame 1 31 can contact the outer wall of the workpiece;

[0065] S3: The spindle drive motor 14 drives the corresponding saw wheel 12 to rotate, and cooperates with another saw wheel 12 to drive the saw belt 13 to rotate. The servo lifting motor 110 drives the corresponding lifting screw 19 to rotate, and cooperates with the corresponding lifting seat 15 to drive the saw frame 1 to move downward. The bottoms of the two sets of chip guards 25 between the guide frame 21 first contact the workpiece, and the chip liquid is injected into the liquid outlet pipe 310 through the external connecting pipe, and then sprayed to the workpiece surface under the saw belt 13 through multiple liquid outlet holes 311 in cooperation with the anti-splash blocking of the chip guards 25 on both sides. After that, the rotating saw belt 13 contacts the workpiece and cuts. During the cutting process, the generated debris moves toward the collecting shell 41 under the impact of the spraying of the cutting liquid, the rotation of the saw belt 13 and the blocking of the chip guards 25 on both sides, and enters the collecting shell 41 through the chip guide filter 42;

[0067] S5: After the chips enter the collection shell 41 through the chip guide filter 42, they fall into the corresponding chip collection filter cover 46 on the chip conveying cylinder 43. The cutting fluid entering the collection shell 41 is discharged through the chip guide filter 42, the chip collection filter cover 46 and the drainage groove 414. The chip conveying motor 411 drives the rotating rod 47 to rotate, and drives the chip conveying cylinder 43 to rotate in the opposite direction under the cooperation of the driving gear 48, the planetary gear 410 and the inner gear ring 49, forcing the multiple chip collection filter covers 46 to rotate, collect the chips one by one, and then transport and discharge the collected chips into the chip suction cover 44, and the chips are extracted and collected by the external chip suction device in cooperation with the chip suction pipe 45;

[0068] S6: During the rotation of the rotating rod 47, the plurality of elastic plates 412 are driven to synchronously knock the chip collecting filter cover 46, which can not only knock and dehydrate the chip collecting filter cover 46 during the conveying process, but also knock and discharge the chip collecting filter cover 46 during the chip removal process.
