An automated horizontal sawing machine for processing aluminum alloy workpieces

Abstract

The invention discloses an automated horizontal sawing machine for processing aluminum alloy workpieces. In order to solve the problem that the current sawing machine wastes a lot of time when the cutting saw disk moves up to the initial position and then pushes the workpiece when cutting the aluminum alloy workpiece in multiple sections, so that the multi-section cutting of the entire aluminum alloy workpiece takes a long time, the present invention first separates the fixing clamp from the aluminum alloy workpiece when the cutting saw disk first retracts, and the conveyor belt does not push the aluminum alloy, and stops tightly fixing the aluminum alloy workpiece, thereby preventing the conveyor belt from starting to convey the aluminum alloy workpiece before the cutting saw disk is retracted, thereby preventing the aluminum alloy workpiece from colliding with the cutting saw disk. When the cutting saw disk is completely moved out from the front end of the aluminum alloy workpiece, the conveyor belt starts to push the aluminum alloy workpiece, and the aluminum alloy workpiece is pushed while the cutting saw disk retracts. The retraction of the cutting saw disk and the pushing of the workpiece are performed synchronously, thereby saving the time required for fixing and pushing the aluminum alloy workpiece.

Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy workpiece processing, and in particular to an automatic horizontal sawing machine used for aluminum alloy workpiece processing. Background Art

[0002] The automated horizontal sawing machine is a mechanical equipment used for processing aluminum alloy workpieces. It uses a saw blade as a cutting tool and cuts the aluminum alloy workpiece through a rapidly rotating saw blade. It is an efficient, precise and automated aluminum alloy workpiece processing equipment, widely used in aviation, automobile, electronics, construction and other fields.

[0003] In this regard, China has applied for a patent number: CN211991216U, which discloses a stable sawing machine for processing aluminum alloy products, including: a machine frame, a workbench and a sawing device, the workbench is arranged on the machine frame, the sawing device is arranged above one side of the machine frame, the workbench is provided with a fixing device and a length detection device for fixing the product, and a position-adjustable limit plate is provided on one side of the workbench, and the sawing device, the fixing device, the length detection device and the position-adjustable limit plate are all connected to the control device of the sawing machine. The utility model fixes and limits the product to be sawed by setting a fixing device on the workbench, and then detects the length by the length detection device. When the length is detected to be the required length, the limit plate will move to the end of the profile to limit it, and then it can be sawed by the sawing device. The whole structure is simple and easy to operate, which effectively improves the stability and accuracy of its sawing.

[0004] When the existing automated horizontal sawing machine for processing aluminum alloy workpieces cuts the aluminum alloy workpiece into multiple sections, it is necessary to measure the length of the workpiece each time, and then use the cutting saw disk to move down to cut the aluminum alloy workpiece. After the cutting saw disk completes cutting, the cutting saw disk moves up and returns to the initial position, and then uses tools or manually pushes the workpiece to the bottom of the cutting saw disk so that the aluminum alloy workpiece can be cut again. However, when this type of cutting method is actually used, the process of measuring the workpiece and returning the cutting saw disk to the initial position will waste a lot of time, and when releasing the workpiece to push it and clamping the workpiece to prevent it from shaking during cutting, it will still waste a lot of time, which will make the cutting time of the entire multi-segment cutting process longer.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] 1. The present invention provides an automated horizontal sawing machine for processing aluminum alloy workpieces. When the cutting saw disc body moves down to cut the aluminum alloy workpiece, a fixed clamp is used to clamp and fix the aluminum alloy workpiece to keep it in a fixed state to ensure the cutting effect. After cutting, when the cutting saw disc body moves up and retreats to the initial position, the upward movement stage of the cutting saw disc body is divided into two parts. When the cutting saw disc body retreats first, the conveyor belt body does not push the aluminum alloy. The fixed clamp is first separated from the aluminum alloy workpiece to stop the tight fixation of the aluminum alloy workpiece, thereby preventing the conveyor belt body from starting to transport the aluminum alloy workpiece before the cutting saw disc body retreats to the conveyor belt body, thereby preventing the aluminum alloy workpiece from colliding with the cutting saw disc body. The air avoidance operation is realized.

The aluminum alloy workpiece is pushed while the cutting saw disc body retreats, so that the retreat of the cutting saw disc body and the pushing of the workpiece are carried out synchronously, thereby saving the time required for fixing the aluminum alloy workpiece and pushing the aluminum alloy workpiece, thereby improving the cutting efficiency.

[0020] 2. The present invention proposes an automated horizontal sawing machine for processing aluminum alloy workpieces. By adjusting the position of the movable plate and the second rack, the entire movable plate and the second rack are offset downward, and the second rack will mesh with the second gear later. The later the meshing time of the second rack and the second gear is, the shorter the pushing time of the conveyor belt body will be, and the pushing distance will be shortened. By adjusting the pushing distance of the conveyor belt body, the cutting size of the aluminum alloy workpiece can be adjusted. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] In order to solve the technical problem that when the automatic horizontal sawing machine for processing aluminum alloy workpieces cuts the aluminum alloy workpiece in multiple sections, the cutting saw disc moves up to the initial position and then pushes the workpiece, wasting a lot of time, making the multi-section cutting of the entire aluminum alloy workpiece take a long time, such as Figure 1-Figure 18 As shown, the following preferred technical solutions are provided:

The inner rotating wheels 20 are located on both sides of the inside of the sawing machine body 1 and on one side of the first gear 14. A third gear 19 is arranged on the outside of the inner rotating wheel 20. The bottom of the third gear 19 is meshed with a second gear 18. The front end of the second gear 18 is meshed with a second rack 16. The second rack 16 runs through the inside of the sawing machine body 1 longitudinally. A movable plate 11 is fixed on the top of the second rack 16. When the cutting saw disc body 4 moves down to cut the aluminum alloy workpiece, the fixed clamping plate 9 is used to clamp and fix the aluminum alloy workpiece to keep it in a fixed state to ensure the cutting effect. When the cutting is completed, the cutting saw disc body 4 moves up and back to the initial position, and the upward movement stage of the cutting saw disc body 4 is divided into two parts. In detail, when the cutting saw disk body 4 retreats first, the conveyor belt body 7 does not push the aluminum alloy, and first separates the fixed clamping plate 9 from the aluminum alloy workpiece, stops tightly fixing the aluminum alloy workpiece, thereby preventing the cutting saw disk body 4 from retreating before the conveyor belt body 7 starts to convey the aluminum alloy workpiece, resulting in the problem of collision between the aluminum alloy workpiece and the cutting saw disk body 4, thereby realizing the air avoidance operation, and when the cutting saw disk body 4 is completely moved out from the front end of the aluminum alloy workpiece, the conveyor belt body 7 starts to push the aluminum alloy workpiece, and pushes the aluminum alloy workpiece while the cutting saw disk body 4 retreats, so that the retreat of the cutting saw disk body 4 and the pushing of the workpiece are carried out synchronously, thereby saving the time required for fixing and pushing the aluminum alloy workpiece, and improving the cutting efficiency.

[0044] Guide assemblies 6 are provided on both sides of the supporting cross frame 3, and the guide assemblies 6 include guide columns 61. The guide columns 61 are provided on both sides of the supporting cross frame 3. The outer parts of the guide columns 61 are provided with guide blocks 62. The guide blocks 62 are fixed on both sides of the supporting cross frame 3. The bottom of the guide block 62 is connected to the movable plate 11, and the rear end of the guide block 62 is connected to the first rack 13. The side wall of the guide block 62 is fixed with a first position block 63. Second position blocks 64 are provided on both sides of the inside of the supporting cross frame 3, and the position of the second position block 64 corresponds to that of the first position block 63.

[0045] The top of the outer side of the movable plate 11 is provided with an adjustment component 12, and the adjustment component 12 includes a support sleeve 121, and the support sleeve 121 is sleeved on the top of the outer side of the movable plate 11. Connecting rods 122 are fixed at the middle positions on both sides of the support sleeve 121. The top of the connecting rod 122 is fixedly connected to the bottom of the guide block 62.

When adjusting the position of the movable plate 11 and the second rack 16, the fixing pin 125 is rotated to move the protrusion 126 at its end out of the position hole 123, and the movable plate 11 is pushed down. The position holes 123 at different positions on both sides of the movable plate 11 are directly opposite to the protrusion 126 at the end of the fixing pin 125, and the position of the movable plate 11 and the second rack 16 will change. The longer the movable plate 11 moves downward, the later the meshing time of the second rack 16 and the second gear 18 will be, the shorter the pushing time of the conveyor belt body 7 will be, and the pushing distance will be shortened.

[0046] The inside of the insertion hole 124 is provided with an internal thread, the outside of the fixing pin 125 is provided with an external thread, and the insertion hole 124 and the fixing pin 125 are connected by threads.

The supporting cross frame 3 moves upward, driving the movable plate 11 and the second rack 16 at its bottom to move upward with it. The upward-moving movable plate 11 preferentially moves upward at the front end of the second gear 18. The continuously upward-moving second rack 16 moves to the front end of the second gear 18 and meshes with it to drive the second gear 18 to rotate clockwise.

[0050] A retraction assembly 15 is provided on the outside of the movable rack 8, and the retraction assembly 15 includes a supporting shell 151, which is sleeved on the outside of the movable rack 8. The bottom of the supporting shell 151 is fixedly connected to the sawing machine body 1 and is located on both sides of the top of the conveyor belt body 7. A built-in cavity 152 is provided inside the movable rack 8, and a telescopic spring 153 is provided inside the built-in cavity 152. A movable rod 154 is fixed to the front end of the telescopic spring 153. The movable rod 154 extends through the inner wall of the built-in cavity 152 to the front end of the movable rack 8, and the front end of the movable rod 154 is fixedly connected to the conveyor belt body 7.

[0051] The outer wall of the inner rotating wheel 20 is provided with a connecting component 21, and the connecting component 21 includes a groove 211. The groove 211 is opened on the outer wall of the inner rotating wheel 20. A return spring 212 is fixed inside the groove 211, and an insert block 213 is fixed on the return spring 212. The insert block 213 is inserted into a slot 214, and the slot 214 is opened on the inner wall of the third gear 19.

[0052] The third gear 19 rotates clockwise outside the inner rotating wheel 20, the insert block 213 disengages from the slot 214 and retracts into the groove 211, the third gear 19 is not connected to the inner rotating wheel 20, and the inner rotating wheel 20 does not rotate with the third gear 19, the third gear 19 rotates counterclockwise outside the inner rotating wheel 20, the insert block 213 is inserted into the slot 214, the third gear 19 is connected to the inner rotating wheel 20, and the inner rotating wheel 20 rotates counterclockwise with the third gear 19.

[0053] Specifically, when the sawing machine is used to perform multi-section cutting on an aluminum alloy workpiece, the aluminum alloy workpiece is first placed on the conveyor belt body 7, and the aluminum alloy workpiece is placed at a suitable position at the bottom of the cutting saw disc body 4, and the hydraulic telescopic rod 5 is started to drive the cutting saw disc body 4 to move downward toward the position of the aluminum alloy workpiece, and the aluminum alloy workpiece can be cut by gradually moving. After the cutting is completed, the cutting saw disc body 4 returns to the initial position, and the aluminum alloy workpiece is pushed forward, so that the remaining part of the aluminum alloy workpiece is moved again to the bottom of the cutting saw disc body 4 for the next cutting, and this can be repeated to perform multi-section cutting operations;

[0054] like Fig.18As shown, it is the initial position of the supporting cross frame 3 and the cutting saw disc body 4. At this time, the first position blocks 63 on both sides of the supporting cross frame 3 are located above the second position blocks 64, and the second rack 16 is meshed with the second gear 18. When cutting, the hydraulic telescopic rod 5 is started, and the hydraulic telescopic rod 5 drives the cutting saw disc body 4 at the bottom thereof to move downward toward the position of the aluminum alloy workpiece by pushing the supporting cross frame 3 downward. Since the guide blocks 62 on both sides of the supporting cross frame 3 are connected to the first rack 13 and the movable plate 11, the downward guide blocks 62 drive the first rack 13 to follow and move downward, and the first gear 14 meshed with the first rack 13 moves counterclockwise under the action of the first rack 13. The needle rotates, and the counterclockwise rotating first gear 14 drives the movable rack 8 on its top to move toward the aluminum alloy workpiece placed on the top of the conveyor belt body 7. The fixed clamping plate 9 at the front end of the movable rack 8 is gradually moved toward the position of the aluminum alloy workpiece by the movable rack 8. The supporting cross frame 3 continues to move downward, and the fixed clamping plate 9 will continue to approach the aluminum alloy workpiece. After the fixed clamping plate 9 contacts the aluminum alloy workpiece, the fixed clamping plate 9 will continue to move forward under the action of the movable rack 8. At this time, the position of the fixed clamping plate 9 is inconvenient, and the movable rod 154 will retract into the built-in cavity 152 and squeeze the telescopic spring 153 to shrink it. The purpose of this design is to pre-fix the aluminum alloy workpiece;

[0055] At the same time, the movable plate 11 and the second rack 16 at the bottom thereof will also move with the supporting cross frame 3, and the downwardly moved second rack 16 will drive the meshing second gear 18 to rotate counterclockwise, and the third gear 19 meshing with the second gear 18 will rotate clockwise. When the third gear 19 rotates clockwise, the plug block 213 will disengage from the slot 214 and retract into the groove 211, and the third gear 19 will not be connected with the inner rotating wheel 20, and the inner rotating wheel 20 will not rotate with the third gear 19. Since the two sides of the rotating column at the front end of the conveyor belt body 7 are fixedly connected to the inner rotating wheel 20, the inner rotating wheel 20 will not rotate, and the conveyor belt body 7 will not start to push the aluminum alloy workpiece. The purpose of this design is to prevent the hydraulic telescopic rod 5 from driving the supporting cross frame 3 and the cutting saw disc body 4 at its bottom to move downward for cutting, and the conveyor belt body 7 will start to push the workpiece, causing the workpiece to move forward during cutting, affecting the cutting;

[0056] When the support cross frame 3 continues to move downward to the position where the first position mark block 63 and the second position mark block 64 on both sides thereof are opposite to each other, Fig. 9As shown, the position of the cutting saw disc body 4 is the middle position of the entire stroke, and the first position mark block 63 and the second position mark block 64 are opposite to each other to mark the position of the cutting saw disc body 4. This position is also the position where the cutting saw disc body 4 begins to contact and cut the workpiece, and the height of the selected aluminum alloy workpiece is lower than the height between the cutting saw disc body 4 and the sawing machine body 1 at this position. At the same time, the engagement between the second rack 16 and the second gear 18 that move downward begins to separate. Based on this, the hydraulic telescopic rod 5 is used to continuously push the supporting cross frame 3 and the cutting saw disc body 4 at its bottom to move downward, and the cutting saw disc The main body 4 gradually contacts the workpiece to perform the cutting operation, and after the movable rod 154 is completely retracted into the built-in cavity 152, the fixed clamp plate 9 and the front end of the movable rack 8 are pressed tightly, and when the fixed clamp plate 9 is continuously close to the position of the aluminum alloy workpiece under the action of the movable rack 8, the movable rack 8 cooperates with the fixed clamp plate 9 to form a fixed fixture to clamp and fix the aluminum alloy workpiece, and the second rack 16 is disengaged from the meshing with the second gear 18, and the movable plate 11 moves to the front end of the second gear 18, and the movable plate 11 is not meshed with the second gear 18, and the second gear 18 will not rotate under the action of the movable plate 11;

[0057] After the cutting saw disc body 4 moves down to cut the workpiece, the hydraulic telescopic rod 5 is used to drive the supporting cross frame 3 to move up, so that the cutting saw disc body 4 at the bottom is moved away from the position of the workpiece. At this time, the supporting cross frame 3 continues to move up, which will drive the first rack 13 to move up with it. The moved up first rack 13 will drive the meshed first gear 14 to rotate clockwise. The clockwise rotating first gear 14 drives the meshed movable rack 8 at its top to move toward the position of the aluminum alloy workpiece away from the top of the conveyor belt body 7, and the movable rack 8 and the fixed clamping plate 9 are gradually separated from the tight state. When the movable rack 8 gradually moves away from the position of the aluminum alloy workpiece on the top of the conveyor belt body 7, the movable rod 154 is pushed out from the built-in cavity 152 by the elastic force of the built-in cavity 152, so that the fixed clamping plate 9 still contacts the side wall of the aluminum alloy workpiece to maintain the pre-fixed state of the aluminum alloy workpiece. The pre-fixation of the aluminum alloy can ensure that the position of the aluminum alloy will not shake continuously when the conveyor belt body 7 is used to push the aluminum alloy. The supporting cross frame 3 continues to move upward, and the fixed clamping plate 9 will continue to move away from the aluminum alloy workpiece, separate from the aluminum alloy workpiece and lose its fixation.

[0058] At the same time, the movable plate 11 and the second rack 16 at its bottom will also move up with the supporting cross frame 3. Since the movable plate 11 is not engaged with the second gear 18, when the movable plate 11 is placed at the front end of the second gear 18, whether it moves up or down, it will not cause the second gear 18 to rotate. Fig. 9As shown, when the first position block 63 and the second position block 64 are facing each other, at this time, the second rack 16 at the bottom of the movable plate 11 begins to mesh with the second gear 18, and the supporting cross frame 3 continues to move upward on the basis of this position, and the fixed clamping plate 9 will be completely separated from the aluminum alloy workpiece and lose its fixation. At the same time, the upwardly moved second rack 16 will drive the second gear 18 to rotate clockwise, and the third gear 19 meshing with the second gear 18 will rotate counterclockwise. When the third gear 19 rotates counterclockwise, the insert block 213 is inserted into the slot 214, and the third gear 19 is connected with the inner rotating wheel 20, and the inner rotating wheel 20 rotates counterclockwise with the third gear 19. Since the two sides of the rotating column at the front end of the conveyor belt body 7 are fixedly connected with the inner rotating wheel 20, the inner rotating wheel 20 rotates, and the conveyor belt body 7 will start to push the aluminum alloy workpiece until the supporting cross frame 3 moves up to the position as shown. Fig.18 In the initial position shown, the conveyor belt body 7 stops conveying the aluminum alloy workpiece;

[0059] The workpiece is then moved back to its original position and the workpiece is moved back to its original position, so that the workpiece is not moved back to its original position, and the workpiece is not ...

[0060] When the supporting cross frame 3 moves upward and retreats to the initial position, so that the first position mark block 63 and the second position mark block 64 are directly opposite, the second rack 16 and the second gear 18 are just meshed. The second rack 16 continues to move upward at this position, and it will drive the conveyor belt body 7 to convey the aluminum alloy workpiece. The later the second rack 16 and the second gear 18 are meshed, the shorter the pushing time of the conveyor belt body 7 is, and the shorter the distance of the aluminum alloy workpiece is conveyed. By adjusting the position of the movable plate 11 and the second rack 16, the entire movable plate 11 and the second rack 16 are offset downward, and the second rack 16 will mesh with the second gear 18 later.

[0061] When adjusting the position of the movable plate 11 and the second rack 16, the fixing pin 125 is rotated to move the protrusion 126 at its end out of the position hole 123, and the movable plate 11 is pushed down. The position holes 123 at different positions on both sides of the movable plate 11 are directly opposite to the protrusion 126 at the end of the fixing pin 125, and the position of the movable plate 11 and the second rack 16 will change. The longer the movable plate 11 is moved down, the later the meshing time of the second rack 16 and the second gear 18 is, the shorter the pushing time of the conveyor belt body 7 will be, and the pushing distance will be shortened. The position of the movable plate 11 and the second rack 16 corresponding to the appropriate position hole 123 is selected, so that the position hole 123 is directly opposite to the protrusion 126 at the end of the fixing pin 125, and the fixing pin 125 is rotated to make the protrusion 126 screwed into the position hole 123, so as to complete the fixing of the movable plate 11, and at this time, the pushing distance of the conveyor belt body 7 can be adjusted.
