Description

Technical Field

[0001] This utility model relates to the field of screw processing technology, and in particular to a screw cutting device for automotive processing. Background Technology

[0002] In the automotive manufacturing industry, screws are crucial connecting components, and their machining quality directly impacts the overall safety and reliability of the vehicle. The screw cutting device, as a key piece of equipment in screw processing, needs to precisely and stably fix the screw shank to ensure cutting accuracy and quality.

[0003] A search revealed Chinese patent CN222725652U, which discloses a screw processing cutting device for automotive manufacturing. This device uses a hydraulic rod to drive a clamping block to clamp and fix screws of different specifications at multiple angles, resulting in good fixing effect. Activating a cylinder allows a top block to limit the position of the nuts of screws of different specifications. After the screw processing is completed, the top block can be ejected by activating the cylinder. It is applicable to various specifications of screws and has high practicality.

[0004] Based on the above research and existing technology, it was found that most existing screw cutting devices for automotive machining employ simple clamping structures to fix the screw rod. For example, some devices rely on only a few clamping points or a rigid, integral clamping component for fixation. Such structures are difficult to precisely adapt to screw rods of different thicknesses. When the screw rod is thin, the rigid clamping component may deform due to excessive clamping force; while when the screw rod is thick, the clamping may not be tight enough. Furthermore, a few clamping points cannot completely restrict the screw rod's movement during cutting. The vibration generated during cutting can cause the screw rod to shift, seriously affecting cutting accuracy and screw machining quality, making it difficult to meet the high precision requirements of automotive machining. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model proposes a screw cutting device for automotive machining. By inserting three sets of clamping plates into the threaded groove of the screw rod body, and cooperating with the support platform, the screw rod body is clamped and fixed at multiple points. The spacing can be adjusted by the nut and telescopic adjustment components, which can accommodate screw rod bodies of different thicknesses. This effectively prevents the screw rod body from shaking during cutting, achieving stable, reliable, and adjustable clamping and fixing of the screw rod body, providing a stable working foundation for cutting.

[0006] The technical solution to achieve the purpose of this utility model is: a screw cutting device for automobile processing, including a base platform, a screw rod body is provided on the base platform, a threaded groove is provided on the outer cylinder of the screw rod body, a support platform is provided on the top of the base platform, one end of the screw rod body is placed on the support platform, and further includes;

[0007] The limiting baffles are symmetrically arranged on the front two sides of the top of the base platform, and the screw rod body is located between the two sets of limiting baffles.

[0008] The limiting tool holder assembly has two symmetrically arranged sets. Each set of the limiting tool holder assembly includes three clamping plates disposed between the screw rod body and the limiting baffle. Both clamping plates are C-shaped and their openings face the screw rod body. Each set of clamping plates located on the same side of the screw rod body has a through-hole on its side. A threaded rod is connected through the through-holes of the three sets of clamping plates. The threaded rod is provided with multiple sets of nuts. The spacing between the three sets of clamping plates on the threaded rod is controlled by the corresponding nuts threaded on the threaded rod.

[0009] The telescopic adjustment assembly is detachably connected to two sets of limiting baffles on opposite sides of the wall. The adjacent ends of the two sets of telescopic adjustment assemblies are connected to clamping components. The telescopic adjustment assembly is connected to the corresponding limiting tool holder assembly through the clamping components.

[0010] In some embodiments, the limiting baffle includes two sets of rectangular protective plates, the telescopic adjustment assembly includes a cylinder disposed on the outside of the protective plate, a support plate for placing the cylinder is installed on the outer wall of the protective plate, and the output shaft of the cylinder passes through the protective plate and is connected to the corresponding clamping component.

[0011] In some embodiments, the clamping component includes a recessed block, one side of which is connected to the output shaft of the cylinder. The recessed block is engaged with the back of the clamping plate on the corresponding limiting tool holder assembly. Both sides of the recessed block are threaded with first fixing bolts, which thread the recessed block and the back of the corresponding clamping plate together.

[0012] In some embodiments, connecting blocks are fixedly connected to both ends of the cylinder housing, and a second fixing bolt is threaded to the top of the connecting blocks.

[0013] In some embodiments, the base platform is a trapezoidal metal platform.

[0014] Compared with existing technologies, the significant advantages of this invention are:

[0015] Firstly, this utility model incorporates a limiting baffle, a limiting tool holder assembly, and a telescopic adjustment assembly. The limiting tool holder assembly includes multiple C-shaped clamping plates, a threaded rod, and a nut. The telescopic adjustment assembly uses a cylinder to drive the clamping components, controlling the lateral movement of the limiting tool holder assembly. By inserting three sets of clamping plates into the threaded grooves of the screw rod body, and cooperating with the support platform, the screw rod body is clamped and fixed at multiple points. The spacing can be adjusted via the nut and the telescopic adjustment assembly, adapting to screw rod bodies of different thicknesses. This effectively prevents the screw rod body from shaking during cutting, achieving stable, reliable, and adjustable clamping and fixing of the screw rod body, providing a stable working foundation for cutting.

[0016] Secondly, the limiting baffle of this utility model consists of two sets of rectangular protective plates. The cylinder of the telescopic adjustment component is installed on the outside of the protective plate through a support plate, and the cylinder output shaft passes through the protective plate to connect to the clamping component. This structure provides a stable power source for the telescopic adjustment component, making the adjustment of the limiting tool holder component more precise and convenient, and ensuring smooth clamping operation of the screw rod body.

[0017] Thirdly, the clamping component of this utility model uses a concave block to engage with the back of the clamping plate and is fixed by the first fixing bolt thread, which realizes the quick disassembly and replacement of the limit tool holder assembly. This makes it easy to replace the limit tool holder assembly of appropriate specifications according to different processing needs, and improves the flexibility and versatility of the device.

[0018] Fourthly, this utility model provides connecting blocks at both ends of the cylinder housing and fixes the telescopic adjustment component to the outside of the limit baffle through the second fixing bolt, ensuring the stability of the cylinder during operation, enabling the cylinder to stably drive the clamping component and the limit tool holder assembly to move, thereby ensuring a stable clamping effect on the screw rod body.

[0019] Fifthly, this utility model designs the base platform as a trapezoidal metal platform, which increases the stability of the base platform and makes the entire screw cutting device more stable during operation, avoiding the impact of base instability on the cutting quality and efficiency of the screw rod body.

[0020] This invention solves the problems of unstable screw rod fixation, difficulty in adapting to screw rods of different thicknesses, and difficulty in replacing the limit tool holder assembly in existing screw cutting devices, resulting in poor overall stability of the device.

[0028] The present invention will now be described in detail, and the technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0029] This utility model provides an improved screw cutting device for automotive machining. The technical solution of this utility model is as follows:

[0030] Figures 1-4 This is the preferred embodiment of the present invention, which is described below in conjunction with the appendix. Figures 1-4 The present invention will be further described below.

[0031] like Figures 1-4 As shown, a screw cutting device for automotive processing includes a base platform 1, on which a screw rod body 2 is disposed. A threaded groove 201 is formed on the outer cylinder of the screw rod body 2. A support platform 102 is disposed on the top of the base platform 1, and one end of the screw rod body 2 is placed on the support platform 102. The device also includes a limiting baffle, a limiting tool holder assembly, and a telescopic adjustment assembly.

[0032] like Figure 1 As shown, the limiting baffles are symmetrically arranged on both sides of the front edge of the top of the base platform 1, and the screw rod body 2 is located between the two sets of limiting baffles. The limiting baffles provide initial limiting for the screw rod body 2, preventing it from moving freely on the base platform 1, thus ensuring its stability during subsequent processing.

[0033] like Figure 2 and Figure 3 As shown, the limiting tool holder assembly is symmetrically arranged in two sets. Each set of the limiting tool holder assembly includes three clamping plates 3 disposed between the screw rod body 2 and the limiting baffle. Both clamping plates 3 are C-shaped with their openings facing the screw rod body 2. Each set of clamping plates 3 located on the same side of the screw rod body 2 has a through-hole 301, and a threaded rod 302 is connected through the through-holes 301 of the three sets of clamping plates 3. The threaded rod 302 is provided with multiple sets of nuts 303. The spacing between the three sets of clamping plates 3 on the threaded rod 302 is controlled by the threads of the corresponding nuts 303 on the threaded rod 302. With this setting of the limiting tool holder assembly, by inserting the three clamping plates 3 into the grooves of the threaded slide groove 201 of the screw rod body 2, multi-point clamping and fixing of the screw rod body 2 is achieved, which can effectively prevent the screw rod body 2 from shaking during cutting. Furthermore, by adjusting the spacing of the clamping plates 3 by the nuts 303, the limiting tool holder assembly can be adapted to screw rod bodies 2 of different sizes.

[0034] like Figures 1-4 As shown, the telescopic adjustment assembly is detachably connected to two sets of limiting baffles on opposite sides of the wall. Clamping components are connected to adjacent ends of the two sets of telescopic adjustment assemblies, and the telescopic adjustment assembly is connected to the corresponding limiting tool holder assembly via the clamping components. By setting the telescopic adjustment assembly, the two sets of limiting tool holder assemblies can be controlled to adjust laterally towards or opposite directions, thereby allowing the three sets of clamping plates 3 on the same side to insert into the grooves of the threaded sliding grooves 201 of the screw rod body 2. This, in conjunction with the support platform 102, provides stable clamping and fixation of the screw rod body 2. Simultaneously, the distance between the two sets of limiting tool holder assemblies can be adjusted according to the thickness of the screw rod body 2, facilitating cutting processing of screw rod bodies 2 of different thicknesses.

[0035] like Figure 2 As shown, the limiting baffle includes two sets of rectangular protective plates 101. The telescopic adjustment assembly includes a cylinder 5 disposed on the outside of the protective plate 101. A support plate 501 for placing the cylinder 5 is installed on the outer wall of the protective plate 101. The output shaft of the cylinder 5 passes through the protective plate 101 and is connected to the corresponding clamping component. The arrangement of the cylinder 5, the protective plate 101, and the support plate 501 provides a power source for the telescopic adjustment assembly, enabling the telescopic adjustment assembly to adjust the limiting tool holder assembly. The output shaft of the cylinder 5 drives the clamping component and the limiting tool holder assembly to move, thereby realizing operations such as clamping and releasing the screw rod body 2.

[0036] like Figures 1-4As shown, the clamping component includes a recessed block 4. One side of the recessed block 4 is connected to the output shaft of the cylinder 5. The recessed block 4 is recessed into the back of the corresponding limiting tool holder assembly. Both sides of the recessed block 4 are threaded with first fixing bolts 401, which thread the recessed block 4 to the back of the corresponding clamping plate 3. This clamping component design enables quick disassembly and replacement of the limiting tool holder assembly. When the limiting tool holder assembly needs to be replaced, simply loosen the first fixing bolts 401 to separate the recessed block 4 from the clamping plate 3. Conversely, tightening the first fixing bolts 401 securely connects the recessed block 4 to the clamping plate 3, facilitating the replacement of limiting tool holder assemblies of different specifications to meet different processing requirements.

[0037] like Figure 4 As shown, connecting blocks 502 are fixedly connected to both ends of the outer shell of the cylinder 5, and a second fixing bolt 503 is threadedly connected to the top of the connecting blocks 502. Through the cooperation of the fixed connecting blocks 502 and the second fixing bolt 503 on the outer shell of the cylinder 5, the telescopic adjustment assembly can be firmly fixed to the outer surface of the limiting baffle, ensuring the stability of the cylinder 5 during operation. This allows the cylinder 5 to stably drive the clamping component and the limiting tool holder assembly to move, thereby achieving stable clamping of the screw rod body 2.

[0038] like Figure 1 As shown, the base platform 1 is a trapezoidal metal platform. By setting the base platform 1 as a trapezoidal metal platform, the stability of the base platform 1 is increased, making the entire screw cutting device more stable during operation and avoiding the impact of the screw rod body 2 on the cutting process due to the instability of the base platform 1.

[0039] Working principle and usage process of this utility model:

[0040] First, the screw rod body 2 is placed on the support platform 102 of the base 1, and the screw rod body 2 is initially limited by the limiting baffle. Then, the two sets of limiting tool holder assemblies are adjusted laterally towards each other by the telescopic adjustment component, so that the three sets of clamping plates 3 on the same side are inserted into the grooves of the threaded slide groove 201 of the screw rod body 2. The spacing of the clamping plates 3 is adjusted by the nut 303 to achieve multi-point clamping and fixing of the screw rod body 2. Next, the cylinder 5 is used to drive the clamping component and the limiting tool holder assembly to move, further adjusting the position of the limiting tool holder assembly so that it can better clamp the screw rod body 2 stably. When it is necessary to replace the limiting tool holder assembly, the first fixing bolt 401 is loosened to separate the concave block 4 from the clamping plate 3. After replacing with a new limiting tool holder assembly, the concave block 4 is then tightened to firmly connect the new clamping plate 3. Throughout the entire cutting process, the trapezoidal structure of the base platform 1 ensures the stability of the device. The limiting baffle, the limiting tool holder assembly, and the telescopic adjustment assembly work together to achieve stable clamping and cutting of screw rod bodies 2 of different thicknesses.

[0041] The technical means disclosed in this utility model are not limited to those described above, but also include technical solutions composed of equivalent substitutions of the above technical features. Matters not covered in this utility model are common knowledge to those skilled in the art.
