Description

Technical Field

[0001] This utility model belongs to the field of parts inspection technology, specifically relating to a rapid positioning and inspection tooling for a pallet frame. Background Technology

[0002] In fields such as machinery manufacturing, aerospace, and automotive industries, dimensional accuracy inspection of large-mass components is a core link in ensuring product assembly quality and performance. Traditional inspection fixtures typically rely on fixed support platforms combined with manual adjustments or semi-automated equipment to complete part positioning and measurement. However, in practical applications, the following technical defects exist: High dependence on manual labor: Traditional fixtures often use screws, manual clamps, or simple brackets to fix parts, requiring repeated adjustments to meet the field of view or measurement range of the inspection equipment. Especially for large parts weighing over a ton, manual handling and alignment are time-consuming, labor-intensive, and pose safety hazards. Poor dynamic positioning capability: Existing devices lack a coordinated mechanism for rapid lifting and horizontal conveying, making it impossible to adapt to the production line rhythm, resulting in a disconnect between the inspection process and the production cycle. Limitations of hydraulic / pneumatic lifting: Some fixtures use hydraulic or pneumatic lifting mechanisms to adjust the inspection height, but these systems are bulky, have high maintenance costs, and slow response speeds, making it difficult to achieve millimeter-level fine adjustments. Insufficient rigidity of the mechanical structure: Traditional screw lifting mechanisms are prone to deformation due to stress concentration when bearing large-mass parts, affecting the levelness of the inspection platform and thus reducing measurement accuracy.

[0023] Please see Figure 1-4 The technical solution provided in this embodiment is as follows:

[0024] A rapid positioning and inspection fixture for a pallet rack includes,

[0025] Display rack 1, used to support large, heavy parts;

[0026] An auxiliary component is located on the outer wall of the placement frame 1. The auxiliary component includes a base frame 2, a rotating frame 3, a clamping claw 4, a lifting frame 6, a lifting block 7, a driving block 9, an auxiliary frame 10, a roller assembly 11, a housing 901, and a drag-reducing wheel 902. The base frame 2 is located directly below the placement frame 1. The rotating frame 3 is rotatably inserted into both sides of the outer wall of the placement frame 1. The clamping claw 4 is fixedly located on one end of the outer wall of the rotating frame 3. The lifting frame 6 is fixedly located at the bottom of the outer wall of the auxiliary frame 10. The roller assembly 11 is rotatably embedded in the inner wall of the auxiliary frame 10. The lifting block 7 is fixedly located on the outer wall of the lifting frame 6 and matches the driving block 9. The auxiliary frame 10 is slidably embedded in both sides of the inner wall of the placement frame 1. The housing 901 is fitted onto the outer wall of the driving block 9. The drag-reducing wheel 902 is rotatably embedded in the opening of the inner wall of the driving block 9 and matches the lifting block 7.

[0027] In a specific embodiment of this utility model, the base frame 2 is first deployed to the designated working position, then the placement frame 1 is hoisted and positioned directly above the base frame 2, ensuring that the base frame 2 is aligned with the openings of the reinforcing block 102 and the limiting platform 103. The placement frame 1 is then slowly lowered, and the installation is completed. When hoisting parts, the rotating frame 3 and the clamping claw 4 are used. Detection equipment and sensors are installed on the clamping claw 4. When the detection height of the part does not meet the requirements of the equipment, the drive cylinder 5 is activated, causing the drive block 9 to approach the lifting block 7. This causes the drag-reducing wheel 902 and the sleeve 901 to press against the lifting block 7, thus lifting the lifting block 7 and raising / lowering it. The frame 6 rises, driving the auxiliary frame 10 and roller assembly 11 to rise as well, causing the parts to rise at a uniform speed. This facilitates the inspection of the parts by different testing equipment. When large-mass parts need to be moved directly from the production line to the placement frame 1, additional rollers are installed on the inner wall of the mounting groove 101 to align the placement frame 1 with the production line. This allows the parts to be transported directly to the top of the placement frame 1 via the auxiliary frame 10 and roller assembly 11. Then, the drive cylinder 5 is activated, causing the drive block 9 to reset. This causes the auxiliary frame 10 and roller assembly 11 to descend slowly, bringing the parts closer to the placement frame 1 and placing them stably on the top of the outer wall of the placement frame 1.

[0028] Specifically, drive cylinders 5 are fixedly installed on both sides of the top of the outer wall of the base frame 2, and the output end of the drive cylinder 5 is fixedly installed on one side of the outer wall of the drive block 9.

[0029] In a specific embodiment of this utility model, the output end of the drive cylinder 5 is fixedly disposed on one side of the outer wall of the drive block 9, which can ensure the stable transmission of torque.

[0030] Specifically, reinforcing blocks 102 and limiting platforms 103 are fixedly installed at the corners of the outer wall of the display rack 1, and holes are opened in both the reinforcing blocks 102 and the limiting platforms 103. Mounting grooves 101 are opened on both sides of the top of the outer wall of the display rack 1.

[0031] In a specific embodiment of this utility model, mounting grooves 101 are provided on both sides of the top of the outer wall of the display rack 1, which can facilitate the installation of additional rollers.

[0032] Specifically, one end of the base frame 2 is inserted into the opening between the reinforcing block 102 and the limiting platform 103.

[0033] In a specific embodiment of this utility model, one end of the base frame 2 is inserted into the opening between the reinforcing block 102 and the limiting platform 103, which can ensure the stability of the installation.

[0034] Specifically, the housing 901 is fitted onto the outer wall of the lifting block 7, and the contact surfaces of the lifting block 7 and the driving block 9 are both inclined.

[0035] In a specific embodiment of this utility model, the contact surfaces of the lifting block 7 and the driving block 9 are both inclined, which can realize the driving lifting function.

[0036] Specifically, a limiting frame 8 is fixedly installed at the bottom corner of the outer wall of the display rack 1, and the limiting frame 8 matches the auxiliary frame 10.

[0037] In a specific embodiment of this utility model, the limiting frame 8 and the auxiliary frame 10 are matched with each other, and the auxiliary frame 10 can be sewn to prevent it from falling off.

[0038] Working principle:

[0039] Fix the base frame 2 in the designated working position, ensuring its horizontal stability. Use the hoisting equipment to move the placement frame 1 directly above the base frame 2, aligning it with the openings of the reinforcing block 102 and the limiting platform 103. Slowly lower the placement frame 1 so that the top of the base frame 2 inserts into the holes of the reinforcing block 102 and the limiting platform 103, completing the rigid connection. Check the rotation flexibility of the rotating frame 3, ensuring that the clamping claw 4 can freely adjust its angle. Confirm that the sliding rails of the lifting frame 6 and the auxiliary frame 10 are unobstructed and that the roller assembly 11 rotates smoothly. Hoist the heavy part onto the top of the placement frame 1 and fix its position using the limiting frame 8. Install rollers in the mounting slot 101 of the placement frame 1, aligning it with the production line conveyor belt. The part is transported by the production line to the roller assembly 11 of the auxiliary frame 10, where it is rolled and transported to directly above the placement frame 1. Activate the drive cylinder 5 to push the drive block 9. The drive block 9 moves towards the lifting block 7. The inclined surface of the drive block 9 contacts the inclined surface of the lifting block 7 through the drag-reducing wheel 902, converting the horizontal thrust into vertical lift. The lifting block 7 drives the lifting frame 6 to rise. The auxiliary frame 10 and the roller group 11 simultaneously lift the part to the height required by the testing equipment. The rotating frame 3 drives the clamping claw 4 to adjust the orientation of the testing equipment (such as a laser rangefinder or vision sensor) to position and measure the size of the part. After the test is completed, the drive cylinder 5 resets, the drive block 9 retracts, and the auxiliary frame 10 slowly descends to make the part fall back to the placement frame 1. The drive cylinder 5 retracts, and the drive block 9 disengages from the lifting block 7. The lifting frame 6 drives the auxiliary frame 10 to descend to the initial position under the action of gravity. The part is hoisted and unloaded. The tested part is moved out of the placement frame 1 by the hoisting device. The production line outputs the part and starts the roller group 11 to transport the part back to the production line in the opposite direction.

[0040] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
