Description

Technical Field

[0001] This utility model relates to the technical field of cutting, and in particular to a cutting device for tractor parts. Background Technology

[0002] In the production and repair of tractor parts, the driveshaft, as a critical force-transmitting component, directly affects assembly accuracy and operational performance due to the precision of its length. Therefore, during the machining process, a cutting device is often used to precisely cut the driveshaft to the required length.

[0003] In the prior art, the utility model patent with patent application number 201820881487.2 discloses a workpiece cutting device, which mainly consists of a base, a saw blade, and a motor. When cutting a workpiece, the operator first measures the workpiece, then marks the parts of the workpiece that need to be cut with a marker, then places the workpiece on the base and moves it until the operator observes that the marked cutting parts on the workpiece are below the saw blade. Then, the motor rotates the saw blade, and then the saw blade descends to cut the workpiece.

[0004] However, it has the following problems when in use: it relies entirely on human judgment, making it difficult to ensure that the marked cutting part coincides precisely with the saw blade, and it is highly dependent on the experience of the operator, making it inconvenient to use. Its positioning accuracy is low, which can easily affect the accuracy of the cut dimensions, resulting in poor reliability and practicality. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a tractor parts cutting device that uses laser positioning to determine the overlap between the marked cutting part on the drive shaft and the cutting mechanism. This device has high positioning accuracy, is easy to use, has high reliability, reduces reliance on the experience of the operator, and is highly practical.

[0006] This utility model discloses a tractor parts cutting device, comprising a bracket and a support plate, with the support plate fixedly mounted on the upper end of the bracket; it also includes a support platform, a clamping mechanism, a pushing mechanism, a cutting mechanism, and a positioning mechanism. The support platform is fixedly mounted on the upper end of the support plate, and an arc-shaped groove is provided on the upper part of the support platform. The clamping mechanism is mounted on the upper end of the support plate and has a clamping function. The pushing mechanism is located on the left side of the support plate and has a pushing function. The cutting mechanism is located on the right side of the support plate and has a cutting function. The positioning mechanism has a laser positioning function. When cutting the drive shaft on a tractor, the operator first measures the drive shaft, and then marks the parts on the drive shaft that need to be cut according to the measurement results. The drive shaft is then placed on the upper part of the support platform. A pushing mechanism pushes the drive shaft to the right while a positioning mechanism positions it. The operator uses the positioning mechanism to determine if the marked cutting area coincides with the cutting mechanism. This process continues until the marked cutting area on the drive shaft is below the cutting mechanism. Then, a clamping mechanism presses and fixes the drive shaft to the upper part of the support platform. Finally, the cutting mechanism cuts the drive shaft, ensuring it aligns with the marked cutting area. This method uses laser positioning to ensure the marked cutting area on the drive shaft coincides with the cutting mechanism, resulting in high positioning accuracy, ease of use, high reliability, reduced reliance on operator experience, and high practicality.

[0007] Preferably, the cutting mechanism includes a chainsaw and a lifting mechanism. The chainsaw is mounted on the lifting mechanism, which is used to raise and lower the chainsaw. When cutting the drive shaft, when the marked cutting part on the drive shaft is below the chainsaw, the lifting mechanism is opened to lower the chainsaw. During the descent, the chainsaw contacts the marked cutting part on the drive shaft and cuts the drive shaft.

[0008] Preferably, the lifting mechanism includes a base plate, a linear module, and a lifting block. The linear module is fixedly installed on the upper end of the base plate, and the lifting block is provided on the linear module. The linear module is used to lift the lifting block, and the chainsaw is fixedly installed on the lifting block. When the cutting part on the drive shaft moves below the chainsaw, the linear module is opened, causing the lifting block to descend, which in turn causes the lifting block to drive the chainsaw to descend. During the descent, the chainsaw contacts the cutting part marked on the drive shaft and cuts the drive shaft through the chainsaw.

[0009] Preferably, the positioning mechanism includes a support plate and a linear laser positioning light. The linear laser positioning light is obliquely installed on the upper part of the front end of the support plate, with the oblique direction of the linear laser positioning light pointing downwards. The linear laser positioning light coincides with the chainsaw in the left-right direction. When the drive shaft is moved, the linear laser positioning light is turned on, causing it to emit a linear positioning laser line. When the marked cutting part on the drive shaft coincides with the linear positioning laser line emitted by the linear laser positioning light, it can be ensured that the marked cutting part on the drive shaft is below the chainsaw. Then, the drive shaft is pressed and fixed on the support platform by the clamping mechanism. After that, the chainsaw descends to cut the drive shaft, which facilitates the positioning of the drive shaft.

[0010] Preferably, the clamping mechanism includes a support frame, a hydraulic cylinder, a lifting rod, a sliding rod, a lifting plate, and an arc-shaped pressure block. The support frame is fixedly installed on the upper end of the support plate, the hydraulic cylinder is fixedly installed on the upper end of the support frame, the lifting rod and the sliding rod are both slidably installed on the upper part of the support frame, the power output end of the hydraulic cylinder is connected to the upper end of the lifting rod, the lifting plate is fixedly installed on the lower end of the lifting rod and the sliding rod, and the arc-shaped pressure block is fixedly installed on the lower end of the lifting plate, located above the support platform. Before the drive shaft is cut by the chainsaw, the hydraulic cylinder is opened, causing the lifting rod to drive the lifting plate and the arc-shaped pressure block to descend, so that the arc-shaped pressure block contacts the upper part of the drive shaft. The support platform and the arc-shaped pressure block press and fix the drive shaft, improving the stability of the drive shaft during the cutting process.

[0011] Preferably, the pushing mechanism includes a vertical plate, a servo cylinder, a push rod, a guide rod, a push plate, and a push plate. The servo cylinder is fixedly installed on the left end of the vertical plate. The push rod and the guide rod are both slidably installed on the vertical plate. The power output end of the servo cylinder is connected to the left end of the push rod. The push plate is fixedly installed on the right end of the push rod and the guide rod, and the push plate is fixedly installed on the right end of the push plate. After the drive shaft is placed on the upper end of the support, the servo cylinder is turned on, causing the push rod to drive the push plate and the push plate to move to the right, thereby making the push plate contact the left end of the drive shaft, pushing the drive shaft to the right until the marked cutting part on the drive shaft coincides with the one-line positioning laser line emitted by the one-line laser positioning light; this facilitates the movement of the drive shaft.

[0012] Preferably, the support also includes a high-pressure blower, a gas supply pipe, an air supply pipe, and multiple air blowing pipes. The lower part of the support has multiple interconnected air holes. The output end of the high-pressure blower is connected to the air supply pipe via the gas supply pipe, which is installed on the upper part of the support. The lower ends of the multiple air blowing pipes are all connected to the air supply pipe, and the upper parts of the multiple air blowing pipes are respectively connected to multiple air holes on the support. When the drive shaft is pushed on the upper part of the support by the push plate, the high-pressure blower is turned on, allowing gas to be discharged through the gas supply pipe, air supply pipe, and multiple air blowing pipes. The gas is then blown upwards through the multiple air holes at the lower part of the support, thereby reducing the pressure of the drive shaft on the support, reducing the frictional force when the drive shaft moves on the support, reducing wear between the drive shaft and the support, and improving reliability.

[0013] Compared with the prior art, the advantages of this utility model are: by using laser positioning to determine that the marked cutting part on the transmission shaft coincides with the cutting mechanism, the positioning accuracy is high, it is convenient to use, has high reliability, reduces the dependence on the experience of the staff, and has high practicality.

Detailed Implementation

[0016] To facilitate understanding of this utility model, a more complete description will be given below with reference to the accompanying drawings. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of this utility model more thorough and complete. Example

[0017] like Figures 1 to 5The tractor parts cutting device of this utility model includes a bracket 1, a support plate 2, a support platform 3, a clamping mechanism, a pushing mechanism, a cutting mechanism, and a positioning mechanism. The support plate 2 is fixedly installed on the upper end of the bracket 1, and the support platform 3 is fixedly installed on the upper end of the support plate 2. An arc-shaped groove is provided on the upper part of the support platform 3. The clamping mechanism is installed on the upper end of the support plate 2 and has a clamping function. The pushing mechanism is located on the left side of the support plate 2 and has a pushing function. The cutting mechanism is located on the right side of the support plate 2 and has a cutting function. The positioning mechanism has a laser positioning function. When cutting the drive shaft 26 on the tractor, the operator first measures the drive shaft 26, and then marks the parts on the drive shaft 26 that need to be cut according to the measurement results. The drive shaft 26 is then placed on the upper end of the support 3. A pushing mechanism then pushes the drive shaft 26 to the right, while a positioning mechanism positions it. The operator uses the positioning mechanism to determine if the marked cutting area coincides with the cutting mechanism. This process continues until the marked cutting area on the drive shaft 26 is below the cutting mechanism. The drive shaft 26 is then pressed and fixed to the upper end of the support 3 using a clamping mechanism. Finally, the cutting mechanism cuts the drive shaft 26, ensuring that the marked cutting area on the drive shaft 26 is aligned with the cutting mechanism. This laser positioning method ensures high positioning accuracy, ease of use, high reliability, and reduces reliance on operator experience, making it highly practical.

[0018] like Figure 1 and Figure 2 The cutting mechanism includes a chainsaw 4 and a lifting mechanism. The chainsaw 4 is mounted on the lifting mechanism, which is used to raise and lower the chainsaw 4. When cutting the drive shaft 26, when the marked cutting part on the drive shaft 26 is below the chainsaw 4, the lifting mechanism is opened to lower the chainsaw 4. During the descent, the chainsaw 4 contacts the marked cutting part on the drive shaft 26 and cuts the drive shaft 26 through the chainsaw 4.

[0019] like Figure 1 The lifting mechanism includes a base plate 5, a linear module 6, and a lifting block 7. The linear module 6 is fixedly installed on the upper end of the base plate 5. The lifting block 7 is provided on the linear module 6. The linear module 6 is used to lift the lifting block 7. The chainsaw 4 is fixedly installed on the lifting block 7. When the cutting part on the drive shaft 26 moves below the chainsaw 4, the linear module 6 is opened, causing the lifting block 7 to descend. This causes the lifting block 7 to drive the chainsaw 4 to descend. During the descent, the chainsaw 4 contacts the cutting part marked on the drive shaft 26 and cuts the drive shaft 26.

[0020] like Figure 1 and Figure 5The positioning mechanism includes a support plate 8 and a linear laser positioning light 9. The linear laser positioning light 9 is installed at an angle on the upper part of the front end of the support plate 8, with the angle of the linear laser positioning light 9 pointing downwards. The linear laser positioning light 9 coincides with the chainsaw 4 in the left-right direction. When the drive shaft 26 is moved, the linear laser positioning light 9 is turned on, so that the linear laser positioning light 9 emits a linear positioning laser line. When the marked cutting part on the drive shaft 26 coincides with the linear positioning laser line emitted by the linear laser positioning light 9, it can be ensured that the marked cutting part on the drive shaft 26 is below the chainsaw 4. Then, the drive shaft 26 is pressed and fixed on the support 3 by the clamping mechanism. After that, the chainsaw 4 descends to cut the drive shaft 26, which facilitates the positioning of the drive shaft 26.

[0021] like Figure 1 and Figure 3 The clamping mechanism includes a support frame 10, a hydraulic cylinder 11, a lifting rod 12, a sliding rod 13, a lifting plate 14, and an arc-shaped pressure block 15. The support frame 10 is fixedly installed on the upper end of the support plate 2, and the hydraulic cylinder 11 is fixedly installed on the upper end of the support frame 10. The lifting rod 12 and the sliding rod 13 are both slidably installed on the upper part of the support frame 10. The power output end of the hydraulic cylinder 11 is connected to the upper end of the lifting rod 12. The lifting plate 14 is fixedly installed on the lower end of the lifting rod 12 and the sliding rod 13. The arc-shaped pressure block 15 is fixedly installed on the lower end of the lifting plate 14 and is located above the support platform 3. Before the drive shaft 26 is cut by the chainsaw 4, the hydraulic cylinder 11 is opened, causing the lifting rod 12 to drive the lifting plate 14 and the arc-shaped pressure block 15 to descend, so that the arc-shaped pressure block 15 contacts the upper part of the drive shaft 26. The support platform 3 and the arc-shaped pressure block 15 press and fix the drive shaft 26, improving the stability of the drive shaft 26 during the cutting process.

[0022] like Figure 1 and Figure 2 The pushing mechanism includes a vertical plate 16, a servo cylinder 17, a push rod 18, a guide rod 19, a push plate 20, and a push plate 21. The servo cylinder 17 is fixedly installed on the left end of the vertical plate 16. The push rod 18 and the guide rod 19 are both slidably installed on the vertical plate 16. The power output end of the servo cylinder 17 is connected to the left end of the push rod 18. The push plate 20 is fixedly installed on the right end of the push rod 18 and the guide rod 19. The push plate 21 is fixedly installed on the right end of the push plate 20. After the drive shaft 26 is placed on the upper end of the support 3, the servo cylinder 17 is turned on, causing the push rod 18 to drive the push plate 20 and the push plate 21 to move to the right, thereby making the push plate 21 contact the left end of the drive shaft 26 and pushing the drive shaft 26 to the right until the marked cutting part on the drive shaft 26 coincides with the line positioning laser line emitted by the line laser positioning light 9. This facilitates the movement of the drive shaft 26. Example

[0023] like Figure 1 and Figure 4Based on Embodiment 1, it also includes a high-pressure blower 22, an air supply pipe 23, an air supply pipe 24, and multiple air blowing pipes 25. The lower part of the support 3 is provided with multiple air holes that are connected vertically. The output end of the high-pressure blower 22 is connected to the air supply pipe 24 through the air supply pipe 23. The air supply pipe 24 is installed on the upper end of the support 1. The lower ends of the multiple air blowing pipes 25 are all connected to the air supply pipe 24, and the upper parts of the multiple air blowing pipes 25 are respectively connected to the multiple air holes of the support 3. When the drive shaft 26 is pushed on the upper end of the support 3 by the push plate 21, the high-pressure blower 22 is turned on, so that the gas is discharged through the air supply pipe 23, the air supply pipe 24, and the multiple air blowing pipes 25. Then the gas is blown upward through the multiple air holes at the lower part of the support 3, thereby reducing the pressure of the drive shaft 26 on the support 3, thereby reducing the friction of the drive shaft 26 when it moves on the support 3, reducing the wear between the drive shaft 26 and the support 3, and improving reliability.

[0024] It should be noted that the electrical equipment in this case, such as the linear module 6, chainsaw 4, linear laser positioning light 9, servo electric cylinder 17, and hydraulic cylinder 11, are all connected to an external controller, which coordinates and controls the operation of each electrical device.

[0025] The linear module 6, chainsaw 4, laser positioning light 9, servo electric cylinder 17, and hydraulic cylinder 11 of the tractor parts cutting device of this utility model are all purchased from the market. Technical personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring any creative work from those skilled in the art.

[0026] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
