Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a tooling fixture for automotive parts. Background Technology

[0002] During the machining of automotive parts, tooling fixtures are required to clamp and fix them for subsequent machining operations. However, existing tooling fixtures for automotive parts have poor versatility, and when using tooling fixtures to clamp and fix automotive parts (workpieces), the parts clamped by the clamping components cannot be machined. Therefore, it is usually necessary to process at least twice: first, the parts not clamped by the clamping components are machined; after machining, the clamping components are released, the angle of the automotive parts is manually adjusted, and then the clamping components are used to lock the automotive parts again before machining the previously unmachined parts. This operation is very cumbersome. Utility Model Content

[0046] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0047] Reference Figures 1 to 6 As shown, an embodiment of the present invention provides an automotive parts tooling fixture, comprising: a worktable 100, a rotary table 200, and multiple clamping components 300.

[0048] For example, the rotary table 200 is rotatably mounted on the worktable 100. The rotation axis of the rotary table 200 is coaxial with its own central axis and extends vertically. The upper surface of the rotary table 200 is horizontal to support the workpiece.

[0049] Multiple clamping assemblies 300 are arranged circumferentially along the rotary table 200. Each clamping assembly 300 includes a base frame 310, a mounting portion 320, and a locking portion 330. The base frame 310 is fixed to the worktable 100. The mounting portion 320 is disposed on the base frame 310 and can be vertically adjusted relative to the base frame 310. The mounting portion 320 can also be horizontally adjusted relative to the base frame 310, moving closer to or further away from the rotary table 200. The locking portion 330 is disposed at one end of the mounting portion 320 near the rotary table 200 and is used to abut against and limit the movement of the workpiece against its outer wall. Obviously, the locking portions 330 of the multiple clamping assemblies 300 can cooperate to clamp and fix the workpiece (automotive parts).

[0050] In this embodiment, when using the automotive parts, after placing the workpiece on the rotary table 200, the multiple clamping components 300 are adjusted sequentially. First, the adjusting mounting part 320 is moved vertically relative to the base frame 310 so that the locking part 330 is within the height range of the workpiece. Then, the adjusting mounting part 320 is moved horizontally closer to the rotary table 200, and the locking part 330 is brought into contact with the outer wall of the workpiece. After adjustment, each locking part 330 clamps and fixes the workpiece, and then the workpiece can be processed for the first time. After the first processing is completed, the locking part 330 is released from the workpiece, and the adjusting mounting part 320 is moved horizontally away from the rotary table 200 to leave room for the workpiece to rotate. Then, the rotary table 200 is rotated at a certain angle, and the clamping components 300 are readjusted so that each locking part 330 locks and fixes the workpiece again. Then, the workpiece surface that was not processed before can be processed.

[0051] Understandably, since the mounting part 320 can be vertically adjusted relative to the base frame 310, and the mounting part 320 can be horizontally adjusted to move closer to or further away from the rotary table 200 relative to the base frame 310, the locking part 330 can be placed in different positions by adjusting the position of the mounting part 320, thus enabling the clamping and positioning of workpieces of different sizes and models, which is highly versatile. In addition, this embodiment is provided with a rotatable rotary table 200 to support the workpiece. Therefore, after the workpiece is processed for the first time, the locking of the workpiece can be released first, and then the rotary table 200 can be rotated and adjusted to adjust the angle of the workpiece, so that the workpiece surface previously covered by the locking part 330 is exposed. Finally, the workpiece is re-locked, and the previously unprocessed workpiece surface can be processed. Compared with directly rotating the workpiece, the operation is more convenient.

[0052] Reference Figures 1 to 4 As shown, in some embodiments of this utility model, the automotive parts tooling fixture further includes multiple positioning blocks 400, with positioning pins 410 at their bottom ends; the upper surface of the rotary table 200 is provided with multiple positioning holes 201, and positioning holes 201 are distributed at multiple radial and multiple circumferential positions of the rotary table 200. The number of positioning holes 201 is greater than the number of positioning blocks 400. The positioning holes 201 are used for the insertion of positioning pins 410. Obviously, by inserting positioning pins 410 into positioning holes 201, positioning blocks 400 can be installed on the rotary table 200. Positioning blocks 400 can be used to abut against the outer wall of the bottom of the workpiece, while locking parts 330 can be used to abut against the outer wall of the middle or top of the workpiece. The locking parts 330, in conjunction with positioning blocks 400, can make the positioning of the workpiece more stable and reliable, and improve the quality of subsequent workpiece processing.

[0053] In a further embodiment, the inner wall of the positioning hole 201 is provided with an internal thread, and the outer wall of the positioning pin 410 is provided with an external thread, so that the positioning pin 410 can be threadedly installed in the positioning hole 201, thereby improving the connection stability between the positioning block 400 and the rotary table 200, and thus improving the stability of workpiece positioning.

[0054] Reference Figure 1 , Figure 5 and Figure 6As shown, in some embodiments of this utility model, the base frame 310 is provided with a vertically extending guide rail 311, and a first sliding seat 340 is vertically slidably fitted on the guide rail 311. A first screw 341 is threaded onto the first sliding seat 340, and the first screw 341 is used to lock and fix the first sliding seat 340 onto the guide rail 311. The mounting part 320 is provided on the first sliding seat 340, and the mounting part 320 can move and adjust relative to the first sliding seat 340 in the horizontal direction towards or away from the rotary table 200. When it is necessary to adjust the height of the mounting part 320, the first screw 341 can be loosened first, then the first sliding seat 340 can be vertically slid to the corresponding position, and then the first screw 341 can be tightened again to fix the first sliding seat 340. The operation is very convenient.

[0055] Reference Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the mounting part 320 includes a mounting base 321 and a first mounting shaft 322; the mounting base 321 is used to mount the locking part 330; the first mounting shaft 322 is horizontally arranged at one end of the mounting base 321 away from the rotation center of the rotary table 200; wherein, the first sliding seat 340 is provided with a horizontally penetrating first mounting hole 342 for sliding cooperation with the first mounting shaft 322, and a second screw 343 is threaded on the first sliding seat 340. The second screw 343 is used to lock and fix the first mounting shaft 322 to the first sliding seat 340. When it is necessary to move the mounting part 320 closer to or further away from the rotary table 200 in the horizontal direction relative to the base frame 310, the second screw 343 is loosened first, and then the first mounting shaft 322 is slid relative to the first sliding seat 340 to the corresponding position, and then the second screw 343 is tightened again. The operation is very convenient.

[0056] In a further embodiment, refer to Figure 5 and Figure 6 As shown, the mounting part 320 also includes a second mounting shaft 323, which is disposed on the mounting base 321 and forms an angle with the first mounting shaft 322, that is, the second mounting shaft 323 extends obliquely, and the central axis of the first mounting shaft 322 and the central axis of the second mounting shaft 323 are located in the same vertical plane; wherein, a second sliding seat 350 is vertically slidably fitted on the guide rail 311, and a second mounting hole 351 is provided on the second sliding seat 350, and the second mounting shaft 323 is slidably fitted with the second mounting hole 351.

[0057] Understandably, since the second mounting shaft 323 needs to move and adjust in the horizontal direction, it needs to be long enough. This results in a long section of the second mounting shaft 323 not engaging with the first sliding seat 340. Consequently, when the locking part 330 abuts against the workpiece and processes the workpiece, the mounting part 320 is easily shaken by the reaction force of the workpiece, making it very unstable. Therefore, in this embodiment, in addition to the horizontally set first mounting shaft 322, an inclined extending second mounting shaft 323 is also provided. At the same time, a second sliding seat 350 that can slide and engage with the second mounting shaft 323 is provided on the guide rail 311, thereby forming a stable triangular support and improving the structural stability of the mounting part 320.

[0058] Obviously, when the horizontal adjustment mounting part 320 is moved, the second mounting shaft 323 will slide relative to the second mounting hole 351, and at the same time drive the second sliding seat 350 to move vertically.

[0059] In a further embodiment, refer to Figure 5 and Figure 6 As shown, a third screw 352 and a fourth screw 353 are threadedly installed on the second sliding seat 350. The third screw 352 is used to lock and fix the second sliding seat 350 to the guide rail 311, and the fourth screw 353 is used to lock and fix the second mounting shaft 323 to the second sliding seat 350. By setting the third screw 352 and the fourth screw 353, the installation stability of the mounting part 320 can be further improved. Of course, the third screw 352 and the fourth screw 353 can also be omitted. Since the sliding direction of the second sliding seat 350 is different from the sliding direction of the second mounting shaft 323, the second sliding seat 350 can also provide support for the second mounting shaft 323.

[0060] Based on the above embodiments, when the horizontal adjustment of the mounting part 320 is required, not only the second screw 343 needs to be loosened, but also the third screw 352 and the fourth screw 353 need to be loosened. The first screw 341 only needs to be loosened when the vertical adjustment of the mounting part 320 is required.

[0061] Reference Figure 1 , Figure 5 and Figure 6 As shown, in some embodiments of this utility model, the locking part 330 includes a locking screw 331, which is threadedly installed on the mounting part 320 and extends horizontally. Specifically, the locking screw 331 is threadedly installed on the mounting base 321, and the workpiece can be tightened by screwing the locking screw 331, which is very convenient to operate.

[0062] Understandably, in order to facilitate the tightening of the locking screw 331, a handle can be provided at the end of the locking screw 331 away from the rotation center of the rotary table 200.

[0063] In a further embodiment, the locking part 330 also includes a rubber pad 332, which is disposed at one end of the locking screw 331 near the rotation center of the rotary table 200. The rubber pad 332 is used to abut against the workpiece and limit its movement, thereby preventing damage to the workpiece.

[0064] Reference Figure 1 As shown, in some embodiments of this utility model, the rotary table 200 is provided with a vertically extending rotating shaft 210, which is rotatably mounted on the worktable 100. The automotive parts tooling fixture also includes multiple support parts 500, which are arranged circumferentially along the rotary table 200. Each support part 500 includes a base 510 and a roller 520. The base 510 is mounted on the worktable 100, and the roller 520 is rotatably mounted on the base 510. The rotation axis of the roller 520 extends radially along the rotary table 200, and the top of the roller 520 abuts against the lower surface of the rotary table 200. By providing multiple support parts 500 to support the rotary table 200, the stability of the rotary table 200 during rotation can be improved. Furthermore, by extending the rotation axis of the roller 520 radially along the rotary table 200, the roller 520 can rotate more smoothly, reducing the friction between the roller 520 and the rotary table 200.

[0065] It is conceivable that, in order to facilitate the rotation of the rotary table 200, in some embodiments of this utility model, the automotive parts tooling fixture also includes a drive motor 600, which is connected to the rotating shaft 210 to drive the rotary table 200 to rotate.
