[0003] In the prior art, including the aforementioned patents, tooling fixtures play a crucial role in the production of automotive parts. They are used to position and clamp parts to ensure their accuracy and stability during processing and assembly. However, existing tooling fixtures for automotive parts production are mostly functionally limited, making it difficult to meet the demands of multi-station and diversified production. Furthermore, the positioning and clamping of parts can easily damage their surfaces, affecting their quality and appearance. Therefore, there is a need to design a novel multi-station tooling fixture for automotive parts production to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a multi-station tooling fixture for the production of automotive parts, so as to solve the problems of existing tooling fixtures having single functions and being prone to damaging parts as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station tooling fixture for automotive parts production, comprising a base, a housing mounted on the top of the base, a spring clamping seat engaged with the top of the housing, an automotive parts body engaged with the inside of the spring clamping seat, a positioning component mounted on the top of the housing, a drive motor mounted inside the housing, a swirl fan blade fixedly connected to the output shaft of the drive motor via a coupling, and a guide shield mounted on the outside of the swirl fan blade.

[0006] Furthermore, the top platform of the housing has multiple sets of slots, and the bottom of the spring clamping seat is fitted into the slots. The top of the base is provided with a positioning pin for fixing the housing, and the bottom of the housing is provided with a positioning hole that matches the positioning pin.

[0007] Furthermore, the positioning component includes a drive cylinder, a limit frame, a movable plate, a positioning frame, a return spring, and a three-dimensional needle carving rod. The drive cylinder is installed inside the housing. The limit frame is fixedly connected to the top of the housing. The movable plate is fixedly connected to the output end of the drive cylinder. The positioning frame is fixedly connected to the bottom of the movable plate. The return spring is fixedly connected to the inner wall of the positioning frame. One end of the return spring is fixedly connected to the three-dimensional needle carving rod.

[0008] Furthermore, the support rod of the limiting frame passes through the movable plate, and the bottom of the positioning frame is provided with multiple sets of three-dimensional needle carving rods.

[0009] Furthermore, the positioning components are provided in multiple sets, and the multiple sets of positioning components are arranged along the circumference of the housing.

[0010] Furthermore, a rubber buffer head is provided at the end of the three-dimensional needle engraving rod that contacts the automotive part body, and multiple annular anti-slip grooves are formed on the surface of the rubber buffer head.

[0011] Furthermore, the clamping surface of the spring clamping seat is provided with a plurality of elastic buffer blocks, the elastic buffer blocks are detachably mounted on the spring clamping seat, the clamping surface of the spring clamping seat is provided with threaded holes, and the elastic buffer blocks are fixed in the threaded holes by bolts.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the multi-station tooling fixture for automobile parts production is reasonable and has the following advantages:

[0013] (1) This utility model constructs an efficient multi-station production system through modular design of multiple sets of spring clamping seats and positioning components. The spring clamping seats are made of high-strength spring steel and generate stable clamping force by utilizing elastic deformation. They can be adaptively adjusted according to different specifications of automotive parts. The positioning components are composed of high-precision positioning pins and positioning blocks. The positioning accuracy is achieved through cooperation. This structural design can simultaneously position and clamp multiple automotive parts in parallel. Compared with traditional single-station fixtures, the production efficiency is increased by more than several times, significantly shortening the product processing cycle and reducing the production cost of enterprises. The snap-fit ​​connection between the spring clamping seats and the housing and the detachable design of the elastic buffer block enable the tooling fixture to adapt to automotive parts of different specifications and shapes, improving versatility and flexibility.

[0014] (2) The high elasticity buffer block built into the spring clamping seat is made of polyurethane material. This material has good resilience and wear resistance. Its surface is specially sanded, which can effectively increase the friction with the surface of the parts. When the clamping force is applied, the pressure is dispersed through flexible contact to avoid stress concentration. The rubber buffer head assembled at the front end of the three-dimensional needle carving rod is made of natural rubber in one piece and has excellent shock absorption performance. When the tooling fixture is precisely positioned, the rubber buffer head can adaptively fit the complex curved surface of the parts and absorb the impact force in the positioning process through compression deformation. The two work together to provide all-round protection for the surface of automotive parts in the entire process of part positioning and clamping, from contact to fixation, effectively avoiding scratches, indentations and other damage.

[0015] (3) The heat dissipation structure is composed of a drive motor, a swirl fan blade and a guide shroud to form a high-efficiency heat dissipation system. The drive motor serves as the power source and drives the swirl fan blade to run at high speed with a stable speed, generating a strong airflow. The unique swirl fan blade design enhances the airflow guidance and flow rate through optimized blade angle and surface curvature, effectively improving heat dissipation efficiency. The guide shroud adopts a streamlined structure to accurately guide the airflow generated by the fan blade, so that it evenly covers the heat-generating area of ​​the tooling fixture, quickly removing the heat generated by mechanical operation, friction and electrical component operation. This heat dissipation structure can stably control the working temperature of the core components of the tooling fixture within a reasonable range, significantly reducing the risk of component deformation, aging and failure caused by high temperature, greatly improving the operational stability and service life of the tooling fixture, and ensuring its continuous and reliable operation in long-term, high-intensity working environments.

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5 The present invention provides a technical solution as follows:

[0024] Example 1:

[0025] A multi-station tooling fixture for automotive parts production includes a base 1, a housing 2 mounted on the top of the base 1, a spring clamping seat 3 engaged with the top of the housing 2, an automotive parts body 4 engaged with the inside of the spring clamping seat 3, a positioning component 5 mounted on the top of the housing 2, a drive motor 6 mounted inside the housing 2, a swirl fan blade 7 fixedly connected to the output shaft of the drive motor 6 via a coupling, and a guide shroud 8 mounted on the outside of the swirl fan blade 7.

[0026] Furthermore, multiple slots are provided on the top platform of the housing 2, and the bottom of the spring clamp 3 is engaged with the slots. This engaging connection method facilitates the installation and disassembly of the spring clamp 3, and different specifications of spring clamp 3 can be replaced according to different production needs.

[0027] The above structure has a positioning pin on the top of the base 1 for fixing the housing 2, and a positioning hole on the bottom of the housing 2 that matches the positioning pin. The cooperation between the positioning pin and the positioning hole can ensure the installation accuracy of the housing 2 on the base 1 and improve the overall stability of the tooling fixture.

[0028] Furthermore, the positioning component 5 internally includes a drive cylinder 501, a limit frame 502, a movable plate 503, a positioning frame 504, a return spring 505, and a three-dimensional needle carving rod 506. The drive cylinder 501 is installed inside the housing 2. The limit frame 502 is fixedly connected to the top of the housing 2. The movable plate 503 is fixedly connected to the output end of the drive cylinder 501. The positioning frame 504 is fixedly connected to the bottom of the movable plate 503. The return spring 505 is fixedly connected to the inner wall of the positioning frame 504. One end of the return spring 505 is fixedly connected to the three-dimensional needle carving rod 506.

[0029] When the above structure is working, the drive cylinder 501 drives the movable plate 503 to move downward, which in turn drives the positioning frame 504 and the three-dimensional needle carving rod 506 to move downward synchronously. The three-dimensional needle carving rod 506 contacts the automotive part body 4 and positions it. The return spring 505 can provide a certain buffer force during the positioning process to avoid damage to the parts. The support rod of the limit frame 502 passes through the movable plate 503 and plays a guiding and limiting role in the movement of the movable plate 503, ensuring the stability of the movement of the movable plate 503. In addition, the bottom of the positioning frame 504 is provided with multiple sets of three-dimensional needle carving rods 506, which can position the automotive part body 4 from multiple directions and improve the positioning accuracy.

[0030] Furthermore, the positioning components 5 are provided in multiple sets, and the multiple sets of positioning components 5 are arranged along the circumference of the housing 2, which can simultaneously position multiple automotive parts 4, further improving production efficiency.

[0031] The structure described above has a rubber buffer head at one end of the three-dimensional needle engraving rod 506 that contacts the automotive part body 4. The surface of the rubber buffer head has multiple annular anti-slip grooves. The rubber buffer head can effectively buffer the pressure of the three-dimensional needle engraving rod 506 on the part and prevent damage to the surface of the part. The annular anti-slip grooves increase the friction between the part and the component, making the positioning more secure.

[0032] Furthermore, the clamping surface of the spring clamping seat 3 is provided with multiple elastic buffer blocks. These elastic buffer blocks are detachably mounted on the spring clamping seat 3. The clamping surface of the spring clamping seat 3 has threaded holes, and the elastic buffer blocks are fixed in these threaded holes with bolts. When clamping the automotive component body 4, the elastic buffer blocks provide cushioning and protection, preventing damage to the component surface. The detachable design also facilitates the replacement of elastic buffer blocks of different specifications according to the shape and size of different components, improving the versatility of the tooling fixture.

[0033] The above structure drives the swirl fan blades 7 to rotate when the drive motor 6 is working. The swirl fan blades 7 generate swirling air inside the guide shroud 8, which can quickly remove the heat generated inside the housing 2 by the drive motor 6 and other components, thus playing a heat dissipation role, ensuring the normal working temperature of each component of the tooling fixture, and extending its service life.

[0034] Working principle: When in use, first, according to the specifications and shape of the automotive parts to be processed, select a suitable spring clamping seat 3, fit its bottom into the slot on the top of the housing 2, and then place the automotive part body 4 inside the spring clamping seat 3. The elastic buffer block of the spring clamping seat 3 initially clamps the part.

[0035] Next, the drive cylinder 501 is activated, which pushes the movable plate 503 downward. The movable plate 503 drives the positioning frame 504 and the three-dimensional needle engraving rod 506 downward. The rubber buffer head of the three-dimensional needle engraving rod 506 contacts the automotive part body 4, accurately positioning the part from multiple directions. The return spring 505 provides buffering and reset functions during the positioning process. After positioning is completed, the automotive part can be processed, assembled, and other production operations. During the operation of the tooling fixture, the drive motor 6 drives the vortex fan blade 7 to rotate. The vortex fan blade 7 generates swirling air in the guide shroud 8, which quickly dissipates the heat inside the housing 2, achieving the heat dissipation function.

[0036] Finally, the support rod of the limiting frame 502 passes through the movable plate 503, which guides and limits the movement of the movable plate 503, ensuring the stability of the movement of the movable plate 503. In addition, the bottom of the positioning frame 504 is provided with multiple sets of three-dimensional needle engraving rods 506, which can position the automotive part body 4 from multiple directions and improve the positioning accuracy. When it is necessary to replace the spring clamp seat 3 or the elastic buffer block of different specifications, it is only necessary to remove the spring clamp seat 3 from the housing 2 or unscrew the bolts on the elastic buffer block for replacement.

[0037] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
