[0028] Example
[0029] like Figure 1-4 As shown, an embodiment of the present invention provides a fixture for processing an automobile motor housing, comprising a workbench 1 on which a clamping device is fixedly mounted;
[0030] The clamping device includes an L-shaped plate 2 fixedly mounted on the workbench 1, a pushing cylinder 3 fixedly mounted on the L-shaped plate 2, a fixed block 4 fixedly connected to the output end of the pushing cylinder 3, one end of the fixed block 4 fixedly connected to a connecting seat 5, a slider 6 fixedly connected to the bottom of the connecting seat 5, the slider 6 slidably engaged on the slide rail 7, a base 8 fixedly connected to the workbench 1, a bearing platform 9 rotatably connected to the base 8, a motor housing 10 is placed on the bearing platform 9, a connecting column 11 fixedly connected to one side of the connecting seat 5, a clamping block 12 rotatably connected to the connecting column 11, a hook 13 fixedly connected to the side walls of the two clamping blocks 12, and a tension spring 14 hung between the two hooks 13;
[0031] Workbench 1: Serves as the basic support platform for the entire fixture and provides an installation location for the clamping device.
[0032] L-shaped plate 2: fixedly installed on the workbench 1, providing a stable installation base for pushing components such as the cylinder 3.
[0033] Pushing cylinder 3: installed on the L-shaped plate 2, its output end is connected to the fixed block 4, and the fixed block 4 and subsequent connected components are pushed to move through the telescopic movement of the cylinder to achieve the clamping and loosening operations of the motor housing.
[0034] Fixed block 4: connects the pushing cylinder 3 and the connecting seat 5 to transmit power.
[0035] Connecting seat 5: The bottom is fixedly connected to the slider 6, and one side is fixedly connected to the connecting column 11. It is a connecting hub for multiple components.
[0036] Slider 6: Slidingly engaged on the slide rail 7, cooperating with the connecting seat 5, to ensure the stability and directionality of the connecting seat 5 during the movement.
[0037] Slide rail 7: fixedly installed on the L-shaped plate 2 to provide a sliding track for the slider 6.
[0038] Base 8: fixed on the workbench 1, used for rotationally connecting to the bearing platform 9.
[0039] The supporting platform 9 is used to place the motor housing 10 . The overall height of the supporting platform 9 is flush with the bottom height of the connecting seat 5 , so that the clamping device can fix the motor housing 10 .
[0040] Motor housing 10: The clamped object is placed on the carrier platform 9 for processing.
[0041] Connecting column 11 is fixed on one side of the connecting seat 5 and is connected to the clamping block 12 so that the clamping block 12 can rotate around the connecting column 11 .
[0042] The clamping block 12 is in the shape of an arc block and clamps the motor housing 10 through rotation and the action of the tension spring 14 .
[0043] Hook 13: fixed on the side wall of the clamping block 12, used for hanging the tension spring 14.
[0044] Working principle:
[0045] When it is necessary to process the motor housing of an automobile, the motor housing 10 is first placed on the bearing platform 9. The bearing platform 9 is rotatably connected to the base 8, and the angle of the motor housing 10 can be adjusted as needed.
[0046] Start the push cylinder 3, and the output end of the push cylinder 3 pushes the fixed block 4 to move. The fixed block 4 drives the connecting seat 5 to move, and the slider 6 under the connecting seat 5 slides on the slide rail 7 to ensure the stability and direction of the movement of the connecting seat 5.
[0047] As the connecting base 5 moves, the connecting post 11 on one side of the connecting base 5 drives the clamping block 12 toward the motor housing 10. The clamping block 12 rotates around the connecting post 11, gradually approaching the motor housing 10. Because hooks 13 are fixedly connected to the side walls of the two clamping blocks 12, and a tension spring 14 is placed between the two hooks 13, the tension spring 14 is stretched as the clamping block 12 approaches the motor housing 10, generating tension.
[0048] When the clamping block 12 contacts the motor housing 10 , the tension of the tension spring 14 causes the clamping block 12 to tightly clamp the motor housing 10 , thereby fixing the motor housing 10 .
[0049] When the processing is completed, the cylinder 3 is started in the reverse direction to push the output end of the cylinder 3 to retract, driving the connecting seat 5, the clamping block 12 and other components away from the motor housing 10, the tension spring 14 gradually returns to its original state, the clamping block 12 releases the motor housing 10, and the processed motor housing 10 can be removed from the supporting platform 9.
[0050] Since the clamping devices are distributed in a circle on the workbench 1 and three clamping devices are provided, the motor housing 10 can be evenly clamped from multiple directions, thereby improving the stability and reliability of the clamping and ensuring that the motor housing 10 will not be displaced or shaken during the processing, thereby ensuring the processing accuracy.
[0051] like Figure 1 As shown, in some embodiments, the slide rail 7 is fixedly mounted on the L-shaped plate 2; this can provide a stable guide for the slider 6, ensure that the connecting seat 5 moves accurately and stably, enhance the overall structural stability of the fixture, and facilitate installation and maintenance.
[0052] like Figure 2 As shown, in some embodiments, the overall height of the supporting platform 9 to which the base 8 is rotatably connected is flush with the bottom height of the connecting base 5, allowing the clamping device to secure the motor housing 10; this facilitates the clamping operation: when the height of the supporting platform 9 is flush with the bottom height of the connecting base 5, the clamping device can clamp the motor housing 10 more smoothly and accurately. The clamping block 12 on one side of the connecting base 5 can more easily contact the motor housing 10 and achieve stable clamping thanks to the action of the tension spring 14.
[0053] like Figure 4 As shown, in some embodiments, the clamping block 12 contacts the connecting seat 5 and is rotatably connected thereto, and the clamping block 12 is an arc block; in the process of clamping the motor housing 10, the clamping block 12 can be adaptively adjusted in angle according to the shape and position of the motor housing 10 to ensure that it can fit tightly to the surface of the motor housing 10 and provide a stable clamping force.
[0054] like Figure 3 As shown, in some embodiments, four tension springs 14 are connected between each two clamping blocks 12 to tighten the clamping blocks 12. This connection of multiple tension springs 14 can apply tension to the clamping blocks 12 from multiple directions, making the clamping blocks 12 more stable and reliable when clamping the motor housing 10. The distribution of the four tension springs 14 can evenly distribute the clamping force, preventing damage to a single tension spring 14 due to excessive force.
[0055] like Figure 1As shown, in some embodiments, the clamping devices are distributed circumferentially on the workbench 1, with three clamping devices provided. The three clamping devices work together to provide greater clamping force, ensuring that the motor housing 10 does not loosen during machining. Compared to a single or two clamping devices, three clamping devices can better cope with various machining situations.
[0056] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
