Abstract
Description
Technical Field
[0001] This utility model belongs to the field of positioning tooling technology, specifically relating to a filter grinding positioning tooling. Background Technology
[0002] A filter is a filtering circuit composed of capacitors, inductors, and resistors. A filter can effectively filter out a specific frequency point or frequencies other than that frequency point in a power line to obtain a power signal of a specific frequency, or eliminate a power signal after a specific frequency. In order to reduce costs and improve efficiency, electronic components such as filter circuits are assembled in a die-cast rectangular metal housing.
[0003] In the production and processing of filters, polishing the outer shell is a necessary step. First, positioning fixtures are used to position and fix the filter shell, and then polishing is performed by polishing equipment. Currently, most positioning fixtures clamp the filter shell from both sides, which can ensure stability, but there are blind spots in the polishing process.
[0004] A search revealed that Chinese utility model patent CN221716308U, authorized by the patent, discloses "a CNC machining positioning fixture for a filter," which includes a frame. Clamping components are detachably mounted at both ends of the frame. The clamping components include a cylinder, a platform, a single connecting rod, a double connecting rod, a clamping head, and a connecting column. Notch slots are provided at both ends of the frame. The platform is detachably connected to the notch slots. The cylinder is mounted below the platform, and the output end of the cylinder passes through the platform.
[0005] While existing positioning fixtures, including those mentioned above, solve the problem of blind spots in grinding and avoid affecting the operation of robotic arms during fine finishing grinding, in actual work, even when using multi-degree-of-freedom robotic arms to grind the filter housing, the bottom surface of the filter housing cannot be ground. The filter housing must be disassembled, flipped over, and re-clamped, resulting in low efficiency.
[0006] To address the aforementioned problems, this utility model proposes a filter grinding and positioning fixture. Utility Model Content

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments.

The flipping power mechanism 7 is drivably connected to the flipping beam 5 for driving the flipping beam 5 to rotate. With the above scheme, when using it, first fix the base 1 to the processing table of the grinding equipment with bolts, then place the filter housing to be ground on the placement platform 2, and then start the two A vertical cylinder 3 is used to adjust the height of the inner support clamping mechanism 6 so that the inner support clamping mechanism 6 corresponds to the cavity of the filter housing. Then, the horizontal cylinder 61 is activated, which drives the connecting plate 62 to move, so that the inner support clamping plate 63 moves into the cavity of the filter housing. Finally, the pitch adjustment power mechanism 65 is activated, which drives the two inner support clamping plates 63 to move away from each other, and the two inner support clamping plates 63 clamp the filter housing from the inside to ensure the stability of the filter housing. Finally, the filter housing is polished using a polishing device. When it is necessary to polish other sides of the filter housing, the flipping power mechanism 7 can be activated to drive the flipping beam 5 to rotate, so as to flip the filter housing, which facilitates polishing different sides of the filter housing without re-clamping, thus improving efficiency.
[0044] Optionally, by Figure 1 and Figure 2 As shown in this embodiment, the pitch adjustment power mechanism 65 includes: a fixed plate 651, a bidirectional threaded screw 652, and a first drive motor 653. The two fixed plates 651 are symmetrically fixed to the outer wall of the connecting plate 62. The bidirectional threaded screw 652 is rotatably installed between the two fixed plates 651 and passes through the inner support plate 63 and is connected to the inner support plate 63 by threaded engagement. The first drive motor 653 is fixed on the fixed plate 651 and is used to drive the bidirectional threaded screw 652 to rotate. With the above scheme, when in use, the first drive motor 653 is started to drive the bidirectional threaded screw 652 to rotate. Under the threaded engagement, the two inner support plates 63 move closer to the inward side or move further away from the outward side.
[0045] Preferably, by Figure 1 and Figure 2As shown, the adjustable torque power mechanism 65 also includes: guide rods 654. The two guide rods 654 are symmetrically fixed between the two fixed plates 651, and the guide rods 654 pass through the inner support plate 63. With the above scheme, in use, the two guide rods 654 are used to guide the inner support plate 63, which improves the stability of the inner support plate 63.

With the above solution, the rubber pad 64 has flexibility and anti-slip effect during use. By using the rubber pad 64 to tighten the filter housing, the stability and safety of the filter housing can be effectively improved.
[0047] Optionally, by Figure 1 and Figure 3 As shown, in this embodiment, the tilting power mechanism 7 includes: a fixed shaft 71, a worm gear 72, a perforated mounting lug 73, a worm 74, and a second drive motor 75.

The two perforated mounting lugs 73 are symmetrically fixed to the outer wall of the lifting side plate 4. The worm 74 is rotatably mounted between the two perforated mounting lugs 73 and meshes with the worm gear 72. The second drive motor 75 is fixed on the perforated mounting lugs 73 and is used to drive the worm 74 to rotate. With the above scheme, when in use, the second drive motor 75 is started to drive the worm 74 to rotate. The worm 74 drives the worm gear 72 to rotate through the meshing action. The worm gear 72 drives the tilting beam 5 to rotate through the fixed shaft 71.
[0048] It should be noted that the above solution is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. The worm gear 72 and the worm 74 have reverse self-locking characteristics. Therefore, the flip beam 5 will not rotate without starting the second drive motor 75, and has high stability. In specific use, if the stability requirement is not high, the flip beam 5 can be directly driven by the motor to rotate, or the second drive motor 75 can be replaced by a handwheel, and the worm 74 can be manually rotated.
[0049] Preferably, by Figure 1 As shown, in this embodiment, it also includes a guide column 8, which is fixed to the top surface of the base 1. A guide hole 41 for the guide column 8 to be inserted is machined on the lifting side plate 4. After adopting the above solution, the guide column 8 is used to guide the lifting side plate 4 during use, thereby improving the stability of the lifting side plate 4.
[0050] Preferably, by Figure 1As shown, in this embodiment, the vertical cylinder 3 is a double-rod cylinder, which has high thrust and high balance. In actual use, the vertical cylinder 3 can also be a three-rod cylinder.
[0051] Preferably, by Figure 1 and Figure 2 As shown, in this embodiment, the horizontal cylinder 61 is a double-rod cylinder with high thrust and high balance. In actual use, the horizontal cylinder 61 can also be a triple-rod cylinder.
[0052] It should be noted that the vertical cylinder 3, the horizontal cylinder 61, the first drive motor 653, and the second drive motor 75 are all commercially available conventional equipment with built-in power switches. Those skilled in the art can make conventional selections according to their needs. Their working principles are common knowledge known to those skilled in the art and have been fully disclosed in the prior art, so they will not be elaborated on further in this article.
[0053] The circuit connection involved in this utility model is a common method used by those skilled in the art, and technical inspiration can be obtained through a limited number of experiments. It belongs to the widely used prior art.
[0054] Components not described in detail in this article are existing technologies.
[0055] The working principle and usage process of this utility model: When using the positioning fixture of this utility model, first fix the base 1 to the processing table of the grinding equipment with bolts, and then place the filter housing to be ground on the placement table 2.
[0056] Then, the two vertical cylinders 3 are activated to adjust the height of the inner support clamping mechanism 6 so that the inner support clamping mechanism 6 corresponds to the cavity of the filter housing. Then, the horizontal cylinder 61 is activated to drive the connecting plate 62 to move, so that the inner support clamping plate 63 moves into the cavity of the filter housing.
[0057] Finally, the pitch adjustment power mechanism 65 is activated, which drives the two inner support plates 63 to move away from each other. The two inner support plates 63 are used to tighten the filter housing from the inside to ensure the stability of the filter housing. Finally, the filter housing is polished using a polishing device.
[0058] When it is necessary to polish other sides of the filter housing, the flipping power mechanism 7 can be activated to drive the flipping beam 5 to rotate, so as to flip the filter housing over, making it convenient to polish different sides of the filter housing without re-clamping, which is highly efficient.
[0059] Additionally, it should be noted that this utility model incorporates a placement platform 2 and a vertical cylinder 3. The placement platform 2 supports the filter housing, preventing it from being suspended during polishing and further enhancing its safety and stability during the polishing process. Therefore, when the filter housing needs to be flipped, the vertical cylinder 3 is first activated to raise the filter housing to a suitable height away from the placement platform 2. After the flipping power mechanism 7 is activated to flip the filter housing, the vertical cylinder 3 is then activated again to lower the filter housing to its initial position, and the placement platform 2 is used to support the filter housing once more.
[0060] 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.
