Description

Technical Field

[0001] This utility model relates to the field of tooling technology for air supply unit production lines, and in particular to a component anti-leakage tooling. Background Technology

[0002] In the production process of air supply units, vibration damping pads are crucial components for ensuring the stable operation of the air supply unit. Currently, vibration damping pads are installed manually after being picked up and directly assembled. This method has the following significant drawbacks:

[0003] 1. High risk of missing installation: The vibration damping pads are small in size, and it is difficult to completely avoid the problem of missing installation by relying solely on manual inspection by workers. This can easily lead to unqualified products flowing into subsequent processes.

[0004] 2. Difficulty in re-inspection: The air supply unit has a complex external structure. After the vibration damping pads are installed, it is difficult to effectively re-inspect their installation through conventional means, and it is impossible to detect missing installation problems in time.

[0005] 3. High rework costs: If the vibration damping pad is found to be missing in subsequent processes, due to the complex structure of the air supply unit, it is necessary to disassemble part of the assembled structure to reinstall it. The rework operation is difficult, time-consuming, and may damage other parts, which will significantly increase production costs.

[0006] To address the shortcomings of the existing technologies, this invention proposes a solution, structure, and device for preventing missing parts during assembly, aiming to solve the problems of missing vibration damping pads, difficulty in re-inspection, and high rework costs. Utility Model Content

[0007] To address the technical problems existing in the background art, this utility model proposes a component anti-leakage assembly tooling.

[0008] This utility model proposes a component anti-leakage fixture, which includes fixture legs, fixture plane and workpiece arrangement bolts;

[0009] The tooling support leg is provided in two pieces, which are symmetrically arranged on the left and right sides of the tooling plane, so that the tooling plane is inclined.

[0010] The workpiece arrangement bolt is fixed to the tooling plane by a threaded connection, and the top of the workpiece arrangement bolt is set with a rounded corner structure.

[0011] The workpiece arrangement bolts are used to place vibration damping pads, and the number of vibration damping pads placed on each workpiece arrangement bolt is three sets.

[0012] Preferably, the tooling plane is fixedly connected to the two tooling legs by M6 mounting screws.

[0013] Preferably, the tooling plane forms a 30° angle with the horizontal plane;

[0014] Preferably, the diameter of the straight segment of the workpiece arrangement bolt extending out of the tooling plane is φ6mm, and the height of the straight segment extending out of the tooling plane is 6.5mm. The diameter of the straight segment of the workpiece arrangement bolt extending out of the tooling plane, φ6mm, is smaller than the diameter of the through hole of the vibration damping pad, φ6.2mm, and the difference between the two diameters is controlled within 0.2mm. This ensures that the vibration damping pad can be smoothly fitted into the workpiece arrangement bolt while avoiding excessive shaking of the vibration damping pad on the workpiece arrangement bolt.

[0015] Preferably, a total of 15 workpiece arrangement bolts are arranged on the tooling plane to form 15 sets of vibration damping pad placement units, which are adapted to the vibration damping pad installation requirements of 15 air supply units.

[0016] Preferably, the tooling support leg is a triangular structure, which supports the tooling plane to maintain a stable 30° angle with the horizontal plane, so as to facilitate the placement and removal of the vibration damping pad.

[0017] Preferably, the height of the straight section of the workpiece arrangement bolt extending out of the tooling plane is 6.5mm, which is greater than the sum of the thicknesses of the three damping pads (6mm) and less than the sum of the thicknesses of the four damping pads (8mm), so as to limit the number of damping pads placed on a single workpiece arrangement bolt to no more than 3.

[0018] Preferably, a component leak-proof assembly scheme for the device includes the following steps:

[0019] Step 1: Place the vibration damping pads in groups of 3, and insert them into the workpiece arrangement bolts through their through holes to complete the pre-placement of 15 sets of vibration damping pads;

[0020] Step 2: During the installation of the air supply unit, the production line worker takes 3 vibration damping pads from a workpiece arrangement bolt for each air supply unit and installs them.

[0021] Step 3: During installation, if vibration damping pads are left on the bolts of the workpiece arrangement, it is determined that the corresponding air supply unit has missing vibration damping pads, and the production line workers will immediately reinstall them on the air supply unit.

[0022] Step 4: After the installation of 15 air supply units is completed, replace the new anti-leakage device and check whether any vibration damping pads are left on the bolts of all workpiece arrangement on the replaced anti-leakage device. If any are left, re-inspect and rework the corresponding 15 air supply units.

[0023] In step 3, the real-time re-inspection of missing vibration damping pads is achieved by observing the retention status of the vibration damping pads on the workpiece arrangement bolts. No additional testing equipment is required, and the re-inspection operation can be directly completed by the production line workers.

[0024] In step 4, by matching the number of 15 sets of vibration damping pad placement units with the number of 15 air supply units, centralized re-inspection after batch installation is achieved, reducing the risk of missing workpieces flowing into the next work station.

[0025] The component leak-proof fitting proposed in this utility model has the following beneficial effects:

[0026] 1. Simplified re-inspection process: Without the need for additional testing equipment, production line workers can directly complete real-time and batch re-inspection by observing the retention status of vibration damping pads on the workpiece arrangement bolts, greatly reducing the difficulty of re-inspection operations;

[0027] 2. Reduce the risk of missing installation: Through the pre-placement design of one set of gaskets corresponding to one product, and the dual prevention and control of real-time re-inspection and batch re-inspection, the problem of missing vibration damping gaskets is reduced from the source, and the missing installation rate can be reduced to below 0.1%;

[0028] 3. Reduced rework costs: Due to timely re-inspection (missing parts can be detected during installation), there is no need to disassemble other assembly structures of the air supply unit. Rework is simple, which can reduce rework time costs and the risk of damage to parts, resulting in an overall reduction of rework costs of more than 60%.

[0029] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0030] Figure 1 This is a schematic diagram of the structure of this utility model;

[0031] The labels in the diagram are as follows: 1. Tooling support leg; 2. M6 mounting screw; 3. Tooling plane; 4. Workpiece arrangement bolt; 5. Vibration damping pad. Detailed Implementation

[0032] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0033] like Figure 1The component anti-leakage fixture shown includes fixture legs 1, M6 mounting screws 2, fixture plane 3, and workpiece arrangement bolts 4. The connection and design of each component are as follows:

[0034] Tooling support leg 1: There are two pieces, which are triangular in structure and are symmetrically arranged on the left and right sides of the tooling plane 3. They are used to support the tooling plane 3 and make the tooling plane 3 form a 30° angle with the horizontal plane after installation, so as to facilitate the placement and removal of the vibration damping pad 5.

[0035] Tooling plane 3: Made of rigid plate, it is fixedly connected to two tooling legs 1 by M6 mounting screws 2 to form a stable mounting base; a total of 15 workpiece arrangement bolts 4 are arranged on tooling plane 3 to form 15 sets of vibration damping pads 5 placement units, which are adapted to the installation requirements of vibration damping pads 5 of 15 air supply units.

[0036] Workpiece arrangement bolt 4: It is fixed to the tooling plane 3 by threaded connection, and its structural design meets the following requirements:

[0037] The diameter of the straight section extending from the tooling plane 3 is φ6mm, which is smaller than the diameter of the through hole of the vibration damping pad 5, φ6.2mm (diameter difference 0.2mm). This ensures that the vibration damping pad 5 can be smoothly fitted in, while also preventing the vibration damping pad 5 from wobbling too much on the bolt.

[0038] The height of the straight section extending from the tooling plane 3 is 6.5mm, which is greater than the sum of the thicknesses of the three damping pads 5 (6mm) and less than the sum of the thicknesses of the four damping pads 5 (8mm), thus limiting the number of damping pads 5 placed on a single bolt to no more than 3.

[0039] The top is designed with rounded corners to reduce frictional resistance when the damping pad 5 is inserted, and to avoid scratching the damping pad 5.

[0040] Component leak prevention solution

[0041] Based on the above-mentioned device, this leak-proof installation solution includes the following steps:

[0042] Step 1: Pre-place 5 vibration damping pads

[0043] Place the vibration damping pads 5 in groups of 3, and insert them one by one into the workpiece arrangement bolts 4 through their central through holes, ensuring that each group of vibration damping pads 5 is tightly stacked and does not exceed 3 pieces, thus completing the pre-placement of 15 sets of vibration damping pads 5.

[0044] Step 2: Install vibration damping pad 5

[0045] During the installation of the air supply unit, the production line worker takes 3 vibration damping pads 5 from a workpiece arrangement bolt 4 for each air supply unit and assembles them into the designated position of the air supply unit.

[0046] Step 3: Real-time re-inspection and re-installation

[0047] During installation, workers need to simultaneously check the bolts 4 of the workpiece after it has been removed: if the damping pads 5 are left on the bolts, it is determined that the corresponding air supply unit has a missing damping pads 5, and the air supply unit must be reinstalled immediately to prevent unqualified products from flowing into the next work station.

[0048] Step 4: Batch re-inspection and rework

[0049] After the installation of 15 air supply units is completed, replace the new anti-leakage device and conduct a comprehensive inspection of all workpiece arrangement bolts 4 on the replaced device. If there are any leftover vibration damping pads 5, trace back to the corresponding 15 air supply units and re-inspect them one by one. If any missing installation problems are found, rework and reinstall them in time.

[0050] Production line workers place the assembled anti-leakage device next to the air supply unit assembly station, ensuring that the 30° angle of the tooling plane 3 faces the operating direction for easy access to the gasket.

[0051] When assembling each air supply unit, the worker takes 3 vibration damping pads 5 from a workpiece arrangement bolt 4 and assembles them into the vibration damping mounting position of the air supply unit.

[0052] After taking it, immediately check the bolt: if there is no washer left on the bolt, continue assembling the next product; if there is a washer left, immediately reinstall it on the air supply unit that was just assembled.

[0053] After all the washers on the 15 workpiece arrangement bolts 4 have been removed (i.e., the assembly of 15 air supply units is completed), replace the new anti-leakage device and check the bolts of the replaced device: if no washers are left on any bolts, it means that all 15 products are qualified; if there are washers left on bolts, trace the corresponding products according to the assembly sequence and re-inspect and rework them.

[0054] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
