Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, specifically a CNC tooling and fixture for processing automotive center console back panels. Background Technology

[0002] CNC tooling fixtures are specialized devices used in CNC machine tool machining for precise positioning, reliable clamping, and stable fixation of workpieces. In the field of new energy vehicles, the center console backplane is a core component of the central control system, playing a crucial role. It connects, controls, and monitors various devices, provides customized layouts and interface types, optimizes production processes, reduces production costs, and can integrate new technologies and innovative functions. If tapping of screw holes is required during manufacturing, a CNC tooling fixture is used to clamp and fix the automotive center console panel to ensure smooth tapping.

[0003] For example, patent CN215469747U discloses a CNC tooling fixture for processing automotive center console back panels. The fixture includes a base plate, a base, a pressure plate, and multiple cylinders. The base is symmetrically installed on the left and right sides below the base plate. The cylinders are fixedly installed on the base, with cylinder rods extending upwards from the base plate and their ends fixedly connected to the pressure plate. The upper surface of the base plate has positioning bosses that fit the inner wall of the automotive center console back panel. The pressure plate has through holes corresponding to each threaded hole on the automotive center console back panel for machining the threaded holes. The inner surface of the pressure plate has protrusions corresponding to grooves on the outer surface of the automotive center console back panel and strip grooves corresponding to ribs on the outer surface of the automotive center console back panel. The advantages of this CNC tooling fixture for processing automotive center console back panels are: the use of cylinders to drive the pressure plate for pneumatic pressing of the product ensures high stability during processing, is unaffected by external forces, and guarantees stable processing quality.

[0004] The aforementioned tooling fixture primarily relies on pressure plates and locating bosses to clamp and fix the automotive center console back panel. However, automotive center console back panels typically have customized layouts, and different models require different pressure plate models. Because the cylinder rod end is fixedly connected to the pressure plate, replacing the pressure plate with one suitable for a different center console back panel is extremely inconvenient, time-consuming, and impacts production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figure 1-5 A CNC tooling fixture for processing automotive center console back panels includes a base plate 1 and a cylinder 2. A U-shaped mounting frame 3 is provided above the base plate 1. The output end of the cylinder 2 is fixedly connected to the bottom of the mounting frame 3. A slot 4 is provided on the inner wall of the mounting frame 3. An insert plate 6 is slidably connected inside the slot 4. A pressure plate 5 is fixedly connected to the middle position of the insert plate 6. A baffle 9 is rotatably connected to the front end of the mounting frame 3.

[0023] The CNC tooling fixture for processing automotive center console back panels in this utility model allows for easy replacement of the pressure plate 5. Simply rotate the baffle 9 to displace it from the slot 4 of the mounting frame 3. Then, the insert plate 6, which is fixed to the pressure plate 5, can be pulled out of the slot 4. Next, the insert plate 6 of the new pressure plate 5 can be aligned with the slot 4, and then inserted into the slot 4. Finally, rotate the baffle 9 back to its original position (i.e., the baffle 9 covers the end of the slot 4 again). The replacement of the pressure plate 5 is relatively simple and convenient. Furthermore, the structure of the base plate 1, cylinder 2, and pressure plate 5 in this utility model is similar to that of the prior art, disclosed in patent patent CN215469747U, which discloses a CNC tooling fixture structure for processing automotive center console back panels; therefore, it will not be elaborated upon here.

[0024] like Figure 2 , Figure 3 and Figure 4As shown, guide blocks 7 are provided on both ends of the insert plate 6 near the baffle 9. The guide blocks 7 are fixedly connected to the mounting frame 3. Both ends of the baffle 9 are provided with receiving grooves 11 that match the guide blocks 7.

[0025] Specifically, the guide block 7 has a guiding function, making it easier for the insert plate 6 to align with the slot 4 and for the insert plate 6 to be inserted into the slot 4.

[0026] like Figure 4 and Figure 5 As shown, a rotating shaft 8 is fixedly connected to one end of the mounting frame 3, and a positioning groove 19 is provided on the inner side of the other end of the mounting frame 3. A rotating groove 10 is provided on the end of the baffle 9 near the rotating shaft 8, and a sliding groove 12 is provided on the end of the baffle 9 near the positioning groove 19. A slider 13 is slidably connected inside the sliding groove 12, and a positioning plate 14 matching the positioning groove 19 is fixedly connected to the bottom of the slider 13.

[0027] Specifically, when the baffle 9 is rotated to the state of being aligned with the slot 4 (e.g.) Figure 1 As shown, the sliding slider 13 allows the positioning plate 14 to be inserted into the positioning groove 19, thereby restricting the baffle 9 and making it less prone to shaking, thus improving the effect of the baffle 9 in restricting the insert plate 6 and the pressure plate 5.

[0028] like Figure 4 and Figure 5 As shown, a push plate 17 is provided on the side of the slider 13 away from the pressure plate 5, and the push plate 17 is fixedly connected to the slider 13.

[0029] Specifically, it is more labor-saving and convenient to move the slider 13 by pushing the plate 17.

[0030] like Figure 5 As shown, multiple anti-slip strips 18 are fixedly connected to the side of the push plate 17 away from the slider 13, and the multiple anti-slip strips 18 are distributed at equal intervals.

[0031] Specifically, since the automotive center console back panel is sprayed with cooling and lubricating solutions during the manufacturing process, the surface of the push plate 17 becomes slippery after being contaminated with the solution, making it difficult to push the push plate 17. The anti-slip strip 18 (preferably a rubber strip) can increase the coefficient of friction, making it easier and more convenient for operators to push the push plate 17.

[0032] like Figure 4 As shown, a slide rod 15 is slidably connected to the middle position of the slider 13. The two ends of the slide rod 15 are fixedly connected to the two ends of the slide groove 12 respectively. A compression spring 16 is sleeved on the end of the slide rod 15 near the rotating shaft 8. One end of the compression spring 16 is fixedly connected to the slide groove 12, and the other end of the compression spring 16 is fixedly connected to the slider 13.

[0033] Specifically, when the tooling fixture is working normally, the compression spring 16 will push the slider 13 towards the positioning groove 19, so that the positioning plate 14 can be firmly inserted into the positioning groove 19, thereby preventing the positioning plate 14 from falling out of the positioning groove 19 and causing the positioning plate 14 to be unable to restrict the baffle 9.

[0034] like Figure 5 As shown, the end of the positioning plate 14 away from the rotation axis 8 has a chamfer.

[0035] Specifically, the chamfer makes it easier to insert the positioning plate 14 into the positioning slot 19.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
