Description

Technical Field

[0002] Track links are the connecting parts of engineering machinery tracks and are an essential component of the track chain. Their design and manufacturing quality directly impact their service life and operational performance. The material selection for track links directly affects their strength and wear resistance. Generally speaking, track links are made of carbon steel, alloy steel, and stainless steel. Carbon steel offers excellent strength and wear resistance, making it suitable for tracks under general operating conditions. Alloy steel offers higher strength and wear resistance, making it suitable for tracks under heavy loads and high speeds. Stainless steel offers excellent corrosion resistance, making it suitable for tracks in humid and corrosive environments. The manufacturing process for track links includes forging, heat treatment, and machining. The raw material is forged into its initial shape through forging. Heat treatment then tempers the track link to enhance its strength and wear resistance. Finally, machining completes the track link to ensure dimensional accuracy and surface quality. Surface treatment is also required to improve its wear and corrosion resistance. During production, threaded holes are machined for the track link to facilitate installation.

The method comprises the step of: first, a plurality of machining centers 1 and a plurality of machining centers 2; second, a plurality of machining centers 1 and a plurality of machining centers 2; and third, a plurality of machining centers 1 and a plurality of machining centers 2. The method comprises the step of: first, a plurality of machining centers 1 and a plurality of machining centers 2; and

[0038] The personnel place the processing base 1 in a suitable area, and place the batches of chain track segments 7 inside each clamping component respectively. The clamping component clamps and fixes the chain track segment 7, and opens the drilling component to perform threaded hole processing on the chain track segment 7 on the clamping component. Then, the driving shaft 3 rotates with the two driving rings 4 until the next clamping component corresponds to the drilling component. At this time, the drilling component again performs synchronous thread processing on the multiple chain track segments 7 on the clamping component, and repeats the above steps to continue processing the chain track segments 7. Through the above operations, threaded holes can be processed on batches of chain track segments 7, which further improves production efficiency. Since the clamping component is set, it can meet the needs of chain track segments 7 of various specifications and has stronger adaptability.

Due to the force of the extrusion spring 10, every two clamping plates 8 will approach each other, and a plurality of dividing plates 11 are evenly fixed inside each of the built-in cavities 9, and a plurality of rectangular holes are provided on each clamping plate 8, and the dividing plate 11 is arranged inside the rectangular hole, so that the clamping plate 8 can slide freely along the dividing plate 11. Due to the provision of a plurality of dividing plates 11, a plurality of rectangular cavities will be formed on each positioning plate 6, and each chain track link 7 is placed inside the corresponding rectangular cavity;

[0040] The personnel drives the corresponding two clamping plates 8 away from each other and drives the extrusion spring 10 to compress, then places the chain track segment 7 into the corresponding rectangular cavity, loosens the clamping plates 8, and uses the elastic force of the extrusion spring 10 to drive the clamping plates 8 to clamp and fix the chain track segment 7 until each rectangular cavity is filled. In this way, batch thread processing of the chain track segment 7 can be realized, the stability of the chain track segment 7 is improved, the deviation phenomenon during thread processing is prevented, and the processing accuracy is improved.

[0041] like Figure 1 、 Figure 3 As shown, the drilling assembly includes a movable push plate 12, a sliding groove 13 is provided at the front end of the processing base 1, and the movable push plate 12 is connected to the interior of the sliding groove 13 for sliding back and forth. A load plate 14 is fixedly connected to the top of the movable push plate 12, and a threaded drill 15 is provided on the load plate 14. The threaded drill 15 can be selected from existing suitable components and is connected to the controller and power supply;

[0042] After the personnel places the chain track segment 7 into the corresponding rectangular cavity, they release the clamping plate 8, squeeze the elastic force of the spring 10, and drive the clamping plate 8 to clamp and fix the chain track segment 7 until each rectangular cavity is filled. At this time, the angle between the frontmost positioning plate 6 and the processing base 1 is 90 degrees, and each chain track segment 7 is set corresponding to the threaded drill 15. Turn on multiple threaded drills 15 and rotate synchronously, drive the movable push plate 12 to gradually slide backward, and each threaded drill 15 performs thread processing on the chain track segment 7. When the processing is completed, drive the movable push plate 12 to move forward and take out the threaded drill 15. Repeat the above operation, and batches of chain track segments 7 can be threaded, and the processed threaded holes are consistent without deviation.

[0043] like Figure 3 、 Figure 6 As shown, the fixed vertical plate 2 on the left is rotatably connected to a groove wheel plate 16, the drive shaft 3 is coaxially fixedly connected to the groove wheel plate 16, and four built-in holes 17 are evenly opened on the groove wheel plate 16. The built-in holes 17 are arranged corresponding to the middle of the adjacent positioning plate 6. The fixed vertical plate 2 on the left is rotatably connected to a drive disk 18, and the drive disk 18 is arranged on the lower side of the groove wheel plate 16. A toggle shaft 19 is fixedly connected to the drive disk 18. The toggle shaft 19 is away from the center side of the drive disk 18, and the inner diameter of the built-in hole 17 is larger than the outer diameter of the toggle shaft 19. diameter, a carrying plate 20 is fixedly connected to the left end of the processing base 1, and a first motor 21 is fixedly connected to the carrying plate 20. A sprocket group 22 is connected between the first motor 21 and the driving disk 18. The sprocket group 22 includes two sprockets and a chain, one of which is coaxially fixedly mounted on the driving disk 18, and the other sprocket is coaxially fixedly mounted on the rotating shaft of the first motor 21. The first chain is connected between the two sprockets. The first motor 21 is connected to a controller, and the controller is connected to a power supply. The personnel controller can set the speed of the first motor 21;

[0044] The first motor 21 rotates the driving disk 18 through the sprocket set 22, and the toggle shaft 19 gradually enters the corresponding built-in hole 17 to slide, thereby driving the groove wheel plate 16 to rotate with the driving shaft 3, and the corresponding structures rotate synchronously. When the toggle shaft 19 slides out from the complete interior of the built-in hole 17, the groove wheel plate 16 rotates synchronously by a quarter of a distance, and the frontmost chain track segment 7 is exactly corresponding to the thread drill 15. Then, after each thread drill 15 performs thread processing on the chain track segment 7, the movable push plate 12 is driven to reset with the thread drill 15, and the toggle shaft 19 just enters the corresponding built-in hole 17 to slide, and continues to rotate the groove wheel plate 16 by a quarter, and continues to process the chain track segment 7. By controlling the rotation of the groove wheel plate 16 by the first motor 21, intermittent rotation thread processing of the chain track segment 7 can be realized, thereby improving processing efficiency.

[0045] like Figure 10 、 Figure 13 As shown, a rectangular hole 23 is respectively opened at both ends of each of the positioning plates 6, and the rectangular hole 23 is arranged to be connected with the built-in cavity 9. The two ends of each of the clamping plates 8 are respectively slidably connected to the corresponding rectangular hole 23, and the two ends of each of the clamping plates 8 are respectively rotatably connected to the driving connecting rod 24. An extrusion block 25 is provided between the two driving connecting rods 24 on the same side, and the other end of each driving connecting rod 24 is rotatably connected to the corresponding extrusion block 25. A guide frame 26 is fixedly connected to the inside of each of the rectangular holes 23, and a guide rod 27 is fixedly connected to each of the extrusion blocks 25. Each of the guide rods 27 is slidably connected to the inside of the guide frame 26;

[0046] When a person squeezes the corresponding two squeezing blocks 25, the two squeezing blocks 25 will move closer to each other, thereby driving the guide rod 27 to slide along the guide frame 26. After each two clamping plates 8 move away from each other, the chain track segment 7 can be placed and the two squeezing blocks 25 can be released. Due to the elastic force of the squeezing spring 10, the two clamping plates 8 will quickly clamp the chain track segment 7, further improving the convenience of device operation, and the guide rod 27 can prevent the squeezing blocks 25 from shifting.

[0047] like Figure 1 、 Figure 5 As shown, the processing base 1 is fixedly connected to a fixed plate 28, which is arranged at the front side of the mobile push plate 12. The rear end of the fixed plate 28 is fixedly provided with a first telescopic rod 29. The first telescopic rod 29 is an electric telescopic rod and is connected to a power supply and a controller. The telescopic end of the first telescopic rod 29 is fixedly mounted on the mobile push plate 12. The outer end surface of the threaded drill 15 is fixedly mounted on the load plate 14. A first pulley 30 is coaxially fixedly mounted on the front end rotating shaft of each threaded drill 15. A first tensioning belt 31 is connected between the plurality of the first pulleys 30. (The installation method of the first tensioning belt 31 is as shown in FIG. Figure 5 As shown), the diameters of the first pulleys 30 on the left and right sides are larger than the diameter of the first pulley 30 in the middle, so as to avoid the mutual friction phenomenon that occurs during the rotation of the first tensioning belt 31. The mobile push plate 12 is fixedly provided with a second motor 32, and the second motor 32 is connected to the controller and the power supply. The second pulley group 33 includes two second pulleys and a second belt, wherein a second pulley is coaxially fixedly installed on one of the first pulleys 30, and another second pulley is coaxially fixedly installed on the rotating shaft of the second motor 32, and the second belt is connected between the two second pulleys;

[0048] Turn on the power, the controller starts the first telescopic rod 29 to push the movable push plate 12 to move, thereby driving the thread drill 15 to move, and the controller starts the second motor 32 to rotate the corresponding first pulley 30 through the second pulley group 33. The first tensioning belt 31 rotates multiple first pulleys 30 and the thread drill 15 synchronously, thereby realizing the thread processing of the chain track segment 7, and the device can select the installation method of the thread drill 15 according to needs.

[0049] like Figure 3 、 Figure 11 As shown, the two fixed vertical plates 2 are respectively threadedly connected with an adjusting screw 34, and the inner end of each adjusting screw 34 is rotatably connected with a semicircular block 35, and each semicircular block 35 is fixedly provided with a directional rod 36, which slides through the corresponding fixed vertical plate 2. When the adjusting screw 34 rotates, due to the setting of the directional rod 36, the semicircular block 35 can only slide left and right and will not rotate. A fixed horizontal plate 37 is respectively fixedly installed on the rear end of the two fixed vertical plates 2, and a second telescopic rod 38 is fixed on each fixed horizontal plate 37. The second telescopic rod 38 is connected to the controller and the power supply;

[0050] The first motor 21 rotates the driving disc 18 through the sprocket set 22, and the toggle shaft 19 gradually enters the corresponding built-in hole 17 to slide, thereby driving the groove wheel plate 16 to rotate with the driving shaft 3, and the corresponding structure rotates synchronously. When the toggle shaft 19 slides out completely from the inside of the built-in hole 17, the groove wheel plate 16 rotates exactly a quarter of the distance. At this time, the frontmost chain track segment 7 is correspondingly set with the thread drill 15. Then, after each thread drill 15 threads the chain track segment 7, it drives the movable push plate 12 to reset with the thread drill 15, and the toggle shaft 19 is The two extrusion blocks 25 are in contact with the circular surfaces of the corresponding semicircular blocks 35. Since the two semicircular blocks 35 remain stationary, the two extrusion blocks 25 are close to each other, thereby driving the guide rod 27 to slide along the guide frame 26. Each two clamping plates 8 are away from each other. The processed chain track segment 7 is no longer subjected to the clamping force and quickly falls into the placement groove of the processing base 1, which collects the chain track segment 7.

[0051] After the idle positioning plate 6 continues to rotate until it is aligned with the rear end of the processing base 1, the angle between the positioning plate 6 and the processing base 1 is 90 degrees. The personnel activates the second telescopic rod 38 through the controller to squeeze the two extrusion blocks 25, and the two clamping plates 8 move away from each other. The personnel holds the corresponding tools (such as suction cups or other suitable tools) to adsorb multiple chain track segments 7 and place them in the rectangular cavity. The controller then activates the second telescopic rod 38 to retract again. Due to the elastic force of the extrusion spring 10, the clamping plate 8 is driven to clamp and fix the chain track segment 7 again. Repeating the above steps can place and process the chain track segment 7, thereby realizing the simultaneous processing and loading and unloading, further improving production efficiency, and not requiring the participation of too many people throughout the process, thereby improving safety.

[0052] like Figure 6 、 Figure 9 、 Figure 12 As shown, the two fixed vertical plates 2 are respectively provided with sleeve holes, and a shaft sleeve 39 is fixedly installed inside each sleeve hole. The drive shaft 3 is rotatably installed inside the two shaft sleeves 39. The two fixed vertical plates 2 are respectively fixedly connected to the ends close to each other with a top pressure spring 40, and the top pressure spring 40 is sleeved on the drive shaft 3. The other end of each top pressure spring 40 is fixedly connected to an extrusion ring 41, and the extrusion ring 41 is sleeved on the drive shaft 3. Key grooves are respectively provided on both ends of the drive shaft 3. A positioning key is fixedly connected to each extrusion ring 41, and the positioning key can only slide left and right along the key groove. Four built-in grooves 42 are evenly provided on the other end of each extrusion ring 41, and a compression spring is fixedly connected to the inner wall of each built-in groove 42. 43, a positioning rod 44 is connected to the inside of each built-in groove 42 for sliding left and right, and the positioning rod 44 can slide left and right along the built-in groove 42, and the positioning rod 44 is fixedly connected to the compression spring 43, and a fixing ring 45 is fixedly installed on the ends away from each other of the two driving rings 4, and the fixing ring 45 is sleeved on the driving shaft 3, and four positioning holes 46 are evenly arranged on the other end surface of each fixing ring 45, and a circular hole is passed through between the four positioning holes 46, and the inner diameter of the positioning hole 46 is larger than the outer diameter of the positioning rod 44, and the outer end of the positioning rod 44 is a circular arc surface. Under normal circumstances, due to the elastic force of the top pressure spring 40 and the compression spring 43, each positioning rod 44 is inserted into the inside of the corresponding positioning hole 46, thereby realizing the positioning of the driving ring 4;

[0053] When the two driving rings 4 rotate synchronously, the arc surface of the positioning rod 44 will gradually move out along the edge of the positioning hole 46, and the driving ring 4 will slide along the circular hole. Since the fixing ring 45 remains stationary, the positioning rod 44 will drive the compression spring 43 to slide inside the fixing ring 45. When the groove wheel plate 16 rotates a quarter, the four positioning rods 44 are just inserted into the corresponding positioning holes 46 again, thereby achieving precise positioning. At the same time, it can also avoid the driving ring 4 from moving around, thereby improving the accuracy of thread processing.
