Description

Technical Field

[0001] This utility model relates to the technical field of attaching annular metal sheets to plate-like parts, and in particular to a mounting fixture for accurately attaching annular metal sheets to plate-like parts. Background Technology

[0002] The structure of plate-type parts produced in a certain workshop is as follows: Figures 1-2 As shown, it includes a plate 1 with a through hole 2. A ring-shaped double-sided adhesive film 3 is pasted directly above the through hole 2. The ring-shaped double-sided adhesive film 3 is circular in shape and is coaxial with the through hole 2. The diameter of the central hole 4 of the ring-shaped double-sided adhesive film 3 is larger than the diameter of the through hole 2 of the plate 1.

[0003] After the workshop produces a batch of sheet metal parts, the process requires that a [material name] be pasted on the other adhesive side of the annular double-sided adhesive film 3. Figures 3-4 The structure of the plate-like part to which the annular metal sheet 5 is attached is as follows: Figure 5 As shown, the annular metal sheet 5 is coaxial with the annular double-sided adhesive film 3, and the diameter of the aperture 6 of the annular metal sheet 5 is smaller than the diameter of the central aperture 4 of the annular double-sided adhesive film 3.

[0004] The method by which workers in the workshop attach a ring-shaped metal piece 5 to each of the ring-shaped double-sided adhesive film 3 of a batch of sheet metal parts is as follows:

[0005] S1. The worker takes out a plate-type part and places the plate body 1 of the plate-type part flat on the workbench.

[0006] S2. The worker takes out a ring-shaped metal sheet 5 from the material basket and presses the ring-shaped metal sheet 5 from top to bottom onto the top surface of the ring-shaped double-sided adhesive film 3. At this time, the adhesive side of the ring-shaped double-sided adhesive film 3 will stick and fix the ring-shaped metal sheet 5, thus realizing the pasting of a ring-shaped metal sheet 5 on the first plate-type part.

[0007] S3. The worker repeats steps S1 to S2 multiple times to continuously attach a ring-shaped metal piece 5 to multiple plate-type parts.

[0008] However, although workers were able to attach a ring-shaped metal piece 5 to each sheet metal part, the following technical defects still existed:

[0009] I. Before each application of the ring-shaped metal sheet 5, a worker needs to take one ring-shaped metal sheet 5 from the material basket before proceeding with the subsequent operations. The process of taking the ring-shaped metal sheet 5 from the material basket wastes time, thereby increasing the time required to apply the ring-shaped metal sheet 5 to the plate-like parts and reducing the efficiency of applying the ring-shaped metal sheet 5.

[0010] II. In step S2, the worker relied solely on experience to attach the annular metal sheet 5 to the annular double-sided adhesive film 3, resulting in misalignment between the annular metal sheet 5 and the annular double-sided adhesive film 3 after attachment. Figure 6 As shown, the process requires that the annular metal sheet 5 and the annular double-sided adhesive film 3 be coaxial after bonding. Therefore, the bonding method used in the workshop has the technical defect of low precision in bonding the annular metal sheet 5.

[0011] Therefore, there is an urgent need for a mounting fixture that can greatly improve the efficiency and accuracy of bonding annular metal sheets. Utility Model Content

[0012] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mounting fixture for accurately bonding annular metal sheets to plate-like parts, which greatly improves the bonding efficiency and accuracy of annular metal sheets.

[0013] The purpose of this utility model is achieved through the following technical solution: a mounting fixture for accurately attaching annular metal sheets to plate-like parts, comprising a cylindrical base, with brackets detachably connected to the bottom surface of the cylindrical base and at its left and right ends; a guide hole is formed on the top surface of the cylindrical base along its axial direction; a square groove penetrating the bottom surface of the cylindrical base is formed at the bottom of the guide hole; a large rod is slidably installed in the guide hole, the diameter of the large rod being equal to the diameter of the aperture of the annular metal sheet; a square rod is fixed on the bottom surface of the large rod, the square rod penetrating downward through the square groove and slidingly engaging with the square groove; a vertical spring is sleeved on the square rod, the top end of the vertical spring is fixed on the bottom surface of the large rod, and the bottom end of the vertical spring is fixed at the bottom of the guide hole.

[0014] The upper end of the large rod extends outside the guide hole, and a small rod is fixed on the top surface of the extended end, which is coaxially arranged with it. The diameter of the small rod is equal to the diameter of the through hole of the plate-like part.

[0015] The bottom surface of the cylindrical base is provided with threaded holes at both its left and right ends, and the top of the two brackets is provided with mounting holes. The brackets are fixed to the cylindrical base by locking screws passing through the mounting holes and threadedly connected to the threaded holes.

[0016] The two supports are symmetrically arranged about the left and right sides of the cylindrical base.

[0017] The top of the small rod is fixed with a conical guide platform that is coaxial with it.

[0018] The square rod is coaxially arranged with the large rod.

[0019] This invention has the following advantages: it greatly improves the bonding efficiency of the annular metal sheet and greatly improves the bonding accuracy of the annular metal sheet. Attached Figure Description

[0040] The present invention will be further described below with reference to the accompanying drawings. The scope of protection of the present invention is not limited to the following description:

[0041] like Figures 7-12 As shown, a mounting fixture for accurately attaching annular metal sheets to plate-like parts includes a cylindrical base 7. Supports 8 are detachably connected to the bottom surface of the cylindrical base 7 and at its left and right ends. The two supports 8 are symmetrically arranged about the cylindrical base 7. A guide hole 9 is formed on the top surface of the cylindrical base 7 along its axial direction. A square groove 10 penetrating the bottom surface of the cylindrical base 7 is formed at the bottom of the guide hole 9. A large rod 11 is slidably installed inside the guide hole 9. The diameter of the large rod 11 is equal to the diameter of the aperture 6 of the annular metal sheet 5. A square rod 12 is fixed on the bottom surface of the large rod 11, penetrating downwards through the square groove 10 and slidingly engaging with it.

[0042] A vertical spring 13 is sleeved on the square rod 12. The top end of the vertical spring 13 is fixed to the bottom surface of the large rod 11, and the bottom end of the vertical spring 13 is fixed to the bottom of the guide hole 9. The upper end of the large rod 11 extends outside the guide hole 9, and a small rod 14 is fixed on the top surface of the extended end, which is coaxially arranged with it. The diameter of the small rod 14 is equal to the diameter of the through hole 2 of the plate body 1 of the plate-like part.

[0043] The cylindrical base 7 has threaded holes 15 on its bottom surface and at both its left and right ends. The tops of the two brackets 8 each have mounting holes. The brackets 8 are fixed to the cylindrical base 7 by locking screws passing through the mounting holes and threadedly connected to the threaded holes 15. The top of the small rod 14 is fixed with a conical guide platform 16 coaxially arranged with it. The square rod 12 is coaxially arranged with the large rod 11.

[0044] The working process of this utility model is as follows:

[0045] S1, Pre-installation of multiple annular metal pieces 5: Workers remove multiple such... Figures 3-4The annular metal sheet 5 shown is passed through the light holes 6 from top to bottom through the conical guide platform 16 and the small rod 14, and finally fitted onto the large rod 11. At this time, multiple neatly stacked annular metal sheets 5 are fitted onto the large rod 11, and the bottommost annular metal sheet 5 is supported on the top surface of the cylindrical base 7, thus finally realizing the pre-installation of multiple annular metal sheets 5, as shown. Figure 13 As shown;

[0046] S2. Attach the ring-shaped metal piece 5 to the first plate-type part. The specific steps are as follows:

[0047] S21, The worker takes out a... Figures 1-2 The plate-like part shown is positioned with its annular double-sided adhesive film 3 facing downwards. Then, the worker places the through hole 2 of the plate body 1 onto the small rod 14 from top to bottom. Since the diameter of the small rod 14 is equal to the diameter of the through hole 2 of the plate body 1, the plate body 1 of the plate-like part is positioned. Figure 14 As shown, at this time, the annular double-sided adhesive film 3 on the plate 1 is coaxial with the top annular metal sheet 5.

[0048] S22. The worker presses down on plate 1 with his hand, in the following direction: Figure 15 As indicated by the middle arrow, the bottom surface of plate 1 is brought into contact with the top surface of the large rod 11, as shown. Figure 15 As shown, the worker then continues to move the plate 1 downwards. The plate 1 moves the large rod 11 downwards, which in turn moves the square rod 12 downwards. The large rod 11 also compresses the vertical spring 13 downwards. When the adhesive surface of the annular double-sided adhesive film 3 presses against the topmost annular metal sheet 5, as shown... Figure 16 As shown, the topmost annular metal sheet 5 is just adhered to the adhesive surface of the annular double-sided adhesive film 3, thus finally realizing the adhesion of an annular metal sheet 5 to the first plate-like part.

[0049] S3. Removal of plate-like parts with the attached annular metal piece 5: The worker releases the hand pressing down on the plate 1. Under the elastic restoring force of the vertical spring 13, the large rod 11 drives the small rod 14 and the square rod 12 to move upward, thereby driving the plate 1 to move upward. After the small rod 14 returns to its original position, the worker removes the plate-like part with the attached annular metal piece 5 from the small rod 14, as follows: Figure 17 As shown;

[0050] S4. The worker repeats steps S1 to S3 multiple times to continuously attach a ring-shaped metal piece 5 to multiple plate-type parts.

[0051] In step S1, since multiple annular metal sheets 5 are already neatly stacked on the top surface of the cylindrical base 7, in step S2, the worker only needs to first fit the through hole 2 of the plate body 1 of the plate-like part onto the small rod 14, and then press the plate body 1 down so that the annular double-sided adhesive film 3 of the plate-like part is attached to the topmost annular metal sheet 5, thus attaching an annular metal sheet 5 to the first plate-like part. Therefore, during the entire pasting process, the worker does not need to retrieve the annular metal sheet 5 from the material basket, saving time spent retrieving the annular metal sheet 5, thereby shortening the time spent pasting the annular metal sheet 5 onto the plate-like parts, and greatly improving the efficiency of pasting annular metal sheets onto plate-like parts.

[0052] Furthermore, in step S21, after the plate body 1 and the small rod 14 of the plate-like part are positioned, since the small rod 14 and the large rod 11 are coaxial, and the large rod 11 is coaxial with the annular metal piece 5 fitted on it, it is ensured that the annular metal piece 5 can be accurately pasted on the annular double-sided adhesive film 3, that is, it is ensured that the annular metal piece 5 and the annular double-sided adhesive film 3 are coaxial. Compared with the method of pasting annular metal pieces by workers based on experience, this mounting fixture greatly improves the efficiency of pasting annular metal pieces on plate-like parts.
