Description

Technical Field

[0001] This utility model relates to the field of wheel and axle processing technology, and in particular to a straightening processing device for wheel and axle on a sawing machine. Background Technology

[0002] The saw wheel axle is the core component of the saw, playing a crucial role in supporting the saw wheel, transmitting power, and maintaining the stable operation of the saw blade. During actual sawing, sudden jamming, unexpected material hardness leading to instantaneous load exceeding the design value, long-term high-speed operation, or poor lubrication causing local overheating can all cause the shaft to undergo elastic or plastic bending, which will then require straightening devices to address the issue.

However, due to different factors that cause bending, the length, bending position, and degree of bending of the wheel axle are also different. The fixed auxiliary heating and hydraulic method cannot effectively control the heating position of the wheel axle, which can easily lead to the wheel axle still being bent, resulting in generally low overall processing efficiency.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0034] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0035] Example 1

[0036] Reference Figure 1 and Figure 2 This is the first embodiment of the present invention. This embodiment provides a straightening treatment device for axle on a sawing machine. The straightening treatment device for axle on a sawing machine includes a bearing component 1, a clamping component 2, a processing component 3, and axle body 4. By setting up the clamping component 2 and the processing component 3, the clamping component 2 can cooperate to position and clamp axle bodies 4 of different sizes, and heat up different positions of the axle body 4, which is beneficial to straightening different positions of the axle body 4. Moreover, the auxiliary heating component and the support component are designed as an integrated unit, and the overall operation is convenient.

[0037] Specifically, the load-bearing component 1 includes a base plate 11, a support frame 12 fixed to the top of the base plate 11, a positioning frame 13 fixed to the top of the support frame 12, and a hydraulic component 14 provided on the top of the base plate 11.

[0038] By setting up the hydraulic component 14, the hydraulic processing position can be flexibly adjusted to perform straightening processing at different positions for different situations of the wheel axle body 4.

[0039] Specifically, the clamping assembly 2 is mounted on the positioning frame 13 and includes a sleeve 21 movably connected to the inner ring of the positioning frame 13. A positioning cylinder 21-1 is fixed to the outer ring of the sleeve 21. A clamping groove 21-2 is opened on the outer ring of the sleeve 21. A screw 22 is provided on the top of the sleeve 21. A displacement seat 23 is threadedly connected to the screw 22. A movable rod 24 is rotatably connected to the bottom of the displacement seat 23. A pressing rod 25 is rotatably connected to the other end of the movable rod 24. A clamping rod 26 is provided in the clamping groove 21-2.

[0040] The bottom end of the screw 22 is designed to be smooth and is mounted on the top of the sleeve 21 via a bearing seat.

[0041] Specifically, the processing component 3 is located on the top of the base plate 11 and includes a stabilizing frame 31 fixed to the top of the support frame 12. A rotating disk 32 is rotatably connected inside the stabilizing frame 31. An induction coil 33 is embedded in the top of the rotating disk 32. A storage groove 34 is opened on the top of the rotating disk 32, and a support platform 35 is provided inside the storage groove 34.

[0042] Instruction manual illustrations Figure 7 This is only a schematic diagram of the shape of the induction coil 33. The actual shape and specifications of the induction coil 33 can be flexibly adjusted according to actual needs.

[0043] There are several induction coils 33, which are distributed in stages on the rotating disk 32. In actual application, the operator can control the induction coil 33 at the corresponding position to work individually, thereby heating different positions on the wheel axle body 4.

[0044] The induction coil 33 is an electromagnetic heater. It uses electromagnetic induction to generate eddy currents in the wheel axle body 4 to raise the temperature, converting electrical energy into electromagnetic energy, and then back into electrical energy. The electrical energy is converted into heat energy inside the metal to achieve the purpose of heating the metal, thereby eliminating the hazards and interference of open flames in the heating process. The working principle of this part is all existing technology, which can be clearly understood by those skilled in the art, and will not be elaborated here.

[0045] By setting up the storage slot 34, the storage space requirements of the support platform 35 can be met.

[0046] Specifically, the axle body 4 is set inside the sleeve 21, and a pin groove 41 is provided on the axle body 4.

[0047] By setting the pin groove 41, it can be used with a flat key, spline or wedge key to achieve circumferential fixation between the wheel and the wheel axle body 4, transmit torque and avoid slippage. The working principle of this part is all existing technology, which can be clearly understood by those skilled in the art, and will not be described in detail here.

[0048] Example 2

[0049] Reference Figures 2-9 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0050] Specifically, the hydraulic assembly 14 includes a fixed frame 14-1 fixed to the top of the base plate 11, a linear motor 14-2 fixed on the fixed frame 14-1, a hydraulic cylinder 14-3 provided at the moving end of the linear motor 14-2, and a hammer head 14-4 fixed at the output end of the hydraulic cylinder 14-3.

[0051] In practical applications, the moving end of the linear motor 14-2 is fixed with a stabilizing seat, and the hydraulic cylinder 14-3 is bolted to the stabilizing seat.

[0052] By setting the linear motor 14-2, the positions of the hydraulic cylinder 14-3 and the hammer head 14-4 can be flexibly adjusted. Thus, when the hydraulic cylinder 14-3 is continuously extending and retracting, the hammer head 14-4 can perform hydraulic straightening of different positions of the wheel axle body 4.

[0053] There are several mounting slots 21-2, which are distributed in a circumferential array on the sleeve 21. The inner wall of the mounting slots 21-2 and the outer ring of the locking rod 26 are both provided with threads 21-21.

[0054] The locking lever 26 is threaded into the mounting slot 21-2 via threads 21-21, as shown in the attached diagram of the instruction manual. Figure 5 As shown, this design can effectively improve the installation stability of the clamp 26, so that the sleeve 21 can be prevented from rotating randomly when the clamp 26 is inserted, and the sleeve 21 is kept at a fixed angle.

[0055] The end of the pressure bar 25 away from the movable bar 24 passes through the positioning cylinder 21-1.

[0056] The outer ring of the sleeve 21 has a through hole 21-3. One end of the pressing rod 25 passes through the through hole 21-3 and extends into the sleeve 21. The pressing rod 25 cooperates with the pin groove 41.

[0057] The positioning cylinder 21-1 and the through hole 21-3 provide space for the displacement of the pressure rod 25 and play an auxiliary guiding role, ensuring the stability of the pressure rod 25's movement. Thus, when the pressure rod 25 is placed into the pin groove 41, the wheel axle body 4 is stably clamped.

[0058] The top of the stabilizer 31 is fixed with a positioning head 31-1, which rotates in conjunction with the outer ring of the rotating disk 32.

[0059] The positioning head 31-1 can position the rotating disk 32, thereby enabling the rotating disk 32 to be driven to rotate flexibly and stably.

[0060] The rotating disk 32 has a screw hole 32-1, and a stud 35-1 is fixed at the center of the bottom of the support platform 35. The stud 35-1 is threadedly connected to the rotating disk 32 through the screw hole 32-1.

[0061] The top of the outer ring of stud 35-1 is designed to be smooth. Its smooth surface is movably connected to the support platform 35 through a cylindrical roller bearing. The cylindrical roller bearing has extremely high radial load capacity and axial load adaptability, while also having low friction, high speed performance, convenient installation structure with separable inner and outer rings, and high rigidity and long service life achieved through optimized design.

[0062] By setting up stud 35-1 and threaded hole 32-1, when driving stud 35-1 to rotate, threaded hole 32-1 can cooperate to make stud 35-1 move up and down synchronously.

[0063] The stabilizer 31 is provided with an anti-slip component 36, including a plug rod 36-1 slidably connected to the stabilizer 31, an anti-slip head 36-2 fixed at one end of the plug rod 36-1, and a spring 36-3 sleeved on the plug rod 36-1.

[0064] One end of spring 36-3 is fixed to the stabilizer 31, and the other end of spring 36-3 is fixed to the plug rod 36-1.

[0065] The rotating disk 32 has anti-slip holes 32-2, which slide in conjunction with the anti-slip head 36-2.

[0066] Both the anti-slip head 36-2 and the anti-slip hole 32-2 are hemispherical. When the rotating disk 32 is actively driven to rotate, the anti-slip head 36-2 and the anti-slip hole 32-2 work together to squeeze the insertion rod 36-1 outward.

[0067] The spring 36-3 provides elastic support, preventing the insertion rod 36-1 from sliding or shifting arbitrarily without external force.

[0068] When in use, first adjust the angle of the axle body 4, and move one end of the axle body 4 into the sleeve 21 until one side of the axle body 4 contacts the inner wall of the sleeve 21.

[0069] The forward-rotating screw 22, under the threaded transmission, causes the displacement seat 23 to move steadily upward, changing the height of the top of the movable rod 24. Then, the bottom of the movable rod 24 is linked to the pressure rod 25 to move inward, passing through the through hole 21-3 and entering the pin groove 41, thus completing the locking of the wheel axle body 4.

[0070] Based on the bending position and degree of bending of the wheel axle body 4, the corresponding induction coil 33 is flexibly controlled to heat the wheel axle body 4, and then the rotating disk 32 is driven to rotate, so that the support platform 35 is placed at the bottom of the wheel axle body 4, and the stud 35-1 is driven to rotate, so that the top of the support platform 35 contacts the bottom of the wheel axle body 4.

[0071] Control the linear motor 14-2 to work, adjust the position of the hydraulic cylinder 14-3 and the hammer 14-4 so that the hammer 14-4 is placed on the wheel axle body 4 at the point to be straightened, and control the hydraulic cylinder 14-3 to extend and retract to complete the hydraulic straightening of the wheel axle body 4.

[0072] When it is necessary to rotate the axle body 4 to change the angle and perform hydraulic straightening at another angle, the locking rod 26 is rotated out of the locking groove 21-2, and the sleeve 21 is driven to rotate. The new locking groove 21-2 on the sleeve 21 is adjusted to align with the locking rod 26, changing the angle of the axle body 4. Then, the locking rod 26 is rotated down to engage with the thread 21-21, thus locking the sleeve 21, which better meets the actual processing requirements.

[0073] Example 3

[0074] Reference Figures 3-9 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0075] Specifically, a handwheel is fixed to the top of screw 22, as shown in the attached diagram of the instruction manual. Figure 5 As shown, it allows workers to easily drive the screw 22 to rotate.

[0076] A protrusion is fixed on one side of the positioning bracket 13, as shown in the attached diagram of the instruction manual. Figure 3 As shown, it is used to provide a sliding mounting position for the locking rod 26 so that when the locking rod 26 is installed, it cooperates with the locking groove 21-2 to prevent the sleeve 21 from rotating randomly.

[0077] Guide rods are fixed on both sides of the bottom of the support platform 35, and guide grooves are opened in the storage slot 34, as shown in the attached diagram of the instruction manual. Figure 7 and Figure 8 As shown, the guide rod and guide groove can effectively improve the stability of the support platform 35 in its up and down movement.

[0078] A rubber buffer layer is provided at the end of the hammer 14-4 to prevent damage to the surface of the wheel axle body 4 during straightening.

[0079] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
