Description

Technical Field

[0001] This utility model relates to the field of truck body processing technology, and in particular to a cutting mechanism for a truck body processing production line. Background Technology

[0002] like Figure 4 As shown, this is the previous generation of cutting mechanism installed on the truck body processing production line. Its main function is to cut the raw material of the truck body bottom beam frame into sections to facilitate the subsequent assembly and welding of the bottom beam frame. However, this type of cutting mechanism for truck body processing production lines has the following shortcomings in actual use: Because it adopts an integrated cutting structure, it is only suitable for flat-edge cutting. Since some batches of bottom beam frames require 45° bevel cutting, the entire cutting mechanism needs to be replaced before subsequent cutting processing can be carried out, which reduces the convenience and applicability of the cutting mechanism.

[0003] In view of this, it is particularly important to design and manufacture a cutting mechanism that can be used for both bevel and flat cutting, improve cutting convenience and applicability, and apply it to truck body processing production lines. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that the previous generation of cutting mechanisms for truck body processing production lines, which adopted an integrated structure, was difficult to adapt to different cutting operations, resulting in poor convenience and low efficiency in the pre-cutting debugging operation. Therefore, a cutting mechanism for truck body processing production lines is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cutting mechanism for a truck body processing production line includes a platform, multiple sliding rollers symmetrically and rotatably mounted on the left and right sides of the upper end of the platform, a top frame disposed in the middle of the upper end of the platform, a lifting slide movably mounted inside the top frame, an electric hydraulic cylinder mounted on the upper end of the top frame and pulsatorically connected to the lifting slide, a support frame symmetrically mounted on the lower end of the lifting slide, a cutting blade rotatably mounted between the lower ends of the two support frames, and a cutting machine mounted between the upper ends of the two support frames and pulsatorically connected to the cutting blade. The upper end of the platform is fixedly connected to the front and rear sides of the middle section with a support rotating frame rotatably connected to the lower end of the top frame. An angle adjustment mechanism for adjusting and fixing the cutting angle of the cutting blade is provided between the support rotating frame and the top frame.

[0007] As a further description of the above technical solution:

[0008] The angle adjustment mechanism includes vertical sliding grooves opened on the front and rear ends of the top frame and facing the supporting rotating frame, three U-shaped buckles fixed at 45° to the upper end of the supporting rotating frame and facing the vertical sliding grooves, a limiting sliding post movably installed between the vertical sliding grooves and the U-shaped buckles, and a rotary locking part set between the platform and the front and rear ends of the top frame.

[0009] As a further description of the above technical solution:

[0010] The rotary locking part includes a support arc frame fixed to the front and rear sides of the upper end of the platform and in contact with the outer wall of the top frame, a guide arc groove opened in the middle of the support arc frame, an inner thread seat fixed to the front and rear ends of the top frame and facing the guide arc groove, and an outer threaded stud installed between the guide arc groove and the inner thread seat by threaded engagement.

[0011] As a further description of the above technical solution:

[0012] A handle is integrally fixed to the outer end of the limiting slide.

[0013] As a further description of the above technical solution:

[0014] The outer end of the external stud is fixedly connected to a knob that can fit against the outer wall of the support arc frame, and an anti-slip rubber ring is sleeved on the outside of the external stud between the knob and the support arc frame.

[0015] As a further description of the above technical solution:

[0016] Mounting ribs are fixedly connected to the four corners at the lower end of the platform, and mounting holes are provided on the mounting ribs.

[0017] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0018] In this invention, the original integrated cutting mechanism has been scientifically and rationally improved. A supporting rotating frame, a U-shaped buckle, a limiting slide column, and a supporting arc frame have been added to the platform. Simultaneously, a vertical sliding groove, an inner threaded seat, an outer threaded stud, and a knob are installed on the top frame. Operating the knob to rotate the outer threaded stud away from the inner threaded seat releases the locking state between the top frame and the supporting arc frame. Then, grasping and sliding the limiting slide column upwards allows it to slide upwards within the vertical sliding groove away from the U-shaped buckle on the supporting rotating frame, releasing the locking state between the top frame and the supporting rotating frame. This allows the entire top frame to be rotated and adjusted between the two supporting rotating frames. This structure allows for tool-free, quick adjustment of the cutting operation to achieve flat or bevel cuts according to the actual cutting requirements of the bottom beam frame. It enables the cutting mechanism to be suitable for both flat and bevel cutting operations, effectively reducing the workload and difficulty of initial debugging in the production line, thereby improving the convenience and applicability of the cutting mechanism in actual use.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figure 1-4 This utility model provides a technical solution: a cutting mechanism for a truck body processing production line, including a platform 1, multiple sliding rollers 101 symmetrically and rotatably installed on the left and right sides of the upper end of the platform 1, a top frame 3 set in the middle of the upper end of the platform 1, a lifting slide 4 movably installed inside the top frame 3, an electric hydraulic cylinder 6 installed on the upper end of the top frame 3 and drivenly connected to the lifting slide 4, a support frame 401 symmetrically installed on the lower end of the lifting slide 4, a cutting blade 5 rotatably installed between the lower ends of the two support frames 401, and a cutting machine 501 installed between the upper ends of the two support frames 401 and drivenly connected to the cutting blade 5. The upper end of the platform 1 is fixedly connected to the front and rear sides of the middle section with a support rotating frame 2 rotatably connected to the lower end of the top frame 3. An angle adjustment mechanism for adjusting and fixing the cutting angle of the cutting blade 5 is provided between the support rotating frame 2 and the top frame 3.

[0027] Specifically, such as Figure 1-3As shown, the angle adjustment mechanism includes vertical sliding grooves 301 opened on the front and rear ends of the top frame 3 and facing the supporting rotating frame 2, three U-shaped buckles 201 fixed at 45° on the upper end of the supporting rotating frame 2 and facing the vertical sliding grooves 301, a limiting sliding post 7 movably installed between the vertical sliding grooves 301 and the U-shaped buckles 201, and a rotating locking part set between the platform 1 and the front and rear ends of the top frame 3. When the limiting sliding post 7 slides into the U-shaped buckles 201 at the corresponding position on the supporting rotating frame 2 in the vertical sliding groove 301, the initial fixing operation of the adjusted angle between the top frame 3 and the platform 1 can be realized.

[0028] The outer end of the limiting slide column 7 is integrally fixedly connected to a handle 701, which facilitates the operator's gripping and sliding adjustment of the limiting slide column 7.

[0029] Specifically, such as Figure 1-3 As shown, the rotary locking part includes a support arc frame 8 fixed to the front and rear sides of the upper end of the platform 1 and in contact with the outer wall of the top frame 3; a guide arc groove 801 opened in the middle of the support arc frame 8; an inner threaded seat 302 fixed to the front and rear ends of the top frame 3 and facing the guide arc groove 801; and an outer threaded stud 9 screwed between the guide arc groove 801 and the inner threaded seat 302. The outer end of the outer threaded stud 9 is fixedly connected to a knob 901 that can fit against the outer wall of the support arc frame 8, and can be gripped and rotated. When the knob 901 is turned inward to abut against the outer wall of the support arc frame 8, the top frame 3 can be further fixed on the platform 1. The outer stud 9 is fitted with an anti-slip rubber ring 10 between the knob 901 and the support arc frame 8. On the one hand, this can prevent the knob 901 from directly and rigidly abutting against the outer wall of the support arc frame 8, preventing contact scratches and pressure damage. On the other hand, it effectively improves the contact friction and locking force between the knob 901 and the support arc frame 8.

[0030] Specifically, such as Figure 1-4 As shown, mounting ribs 102 are fixedly connected to the four corners at the lower end of the platform 1. Mounting ribs 102 are provided with mounting holes. The mounting ribs 102 and mounting holes facilitate the installation and fixing of the platform 1 by fasteners.

[0031] Working principle: During use, the entire platform 1 can be fixedly installed on the cutting station of the truck body processing production line by installing the rib plate 102 and fasteners. Then, the control circuits of the cutting machine 501 and the electric cylinder 6 are connected to the control terminal of the truck body processing production line, thus completing the installation of the cutting mechanism. Before preparing for daily processing, the angle of the top frame 3 can be adjusted according to the actual processing needs to achieve flat or bevel cutting operations. When it is necessary to adjust the cutting mechanism from flat cutting to bevel cutting, the operator can hold and turn the knob 901 in advance to rotate the external stud 9 outward away from the support arc frame 8. At this time, the support arc frame 8 and the top frame 3 are locked. Then, grasp and slide the handle 701 upwards to release the lock. The limiting slide pin 7 will slide upwards within the vertical slide groove 301. When the limiting slide pin 7 slides upwards away from the U-shaped buckle 201, the locking state between the support frame 2 and the top frame 3 is released. The top frame 3 can then be rotated 45° to the left or right between the two support frames 2. Then, slide the limiting slide pin 7 downwards through the vertical slide groove 301 into the U-shaped buckle 201 on the side of the support frame 2. Grasp and rotate the knob 901 so that the knob 901 can tightly abut against the outer wall of the support arc frame 8. This completes the adjustment and fixing of the cutting angle of the cutting blade 5, and the subsequent beveling operation can then be performed.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
