Filter frame. Detailed Implementation

[0022] The above-mentioned and other technical features and advantages of this utility model will be described in more detail below with reference to the accompanying drawings.

[0023] This embodiment provides a technical solution: a high-efficiency magnetic pressing fixture for a gear shifting mechanism, such as... Figure 1-4 As shown, the device includes a pressing mechanism 100, which includes a support frame 110, a pressing fixture body 120 fixedly installed on the top of the support frame 110 for pressing magnets, and a support platform 130 fixedly installed on the top of the support frame 110 for limiting the magnet mounting housing.

[0024] The replacement mechanism 200 includes a magnetic suction component 210 for quick replacement of mounting housings of different sizes, and a heat dissipation component 220 for dissipating heat from the inside of the support platform 130 by using the pressing power of the pressing fixture body 120.

[0025] The magnetic suction component 210 is used to quickly attract and limit the installation of the magnet mounting shell, replacing the traditional mechanical clamping method of manually tightening screws, which greatly shortens the changeover time and improves the magnet pressing efficiency; the heat dissipation component 220 is used to assist the magnetic suction component 210 in heat dissipation, preventing overheating from affecting the equipment performance or causing adverse effects.

[0026] Specifically, the magnetic attraction component 210 includes several electromagnets 211 disposed inside the support platform 130 for attracting and limiting the mounting housing, and a battery 212 fixedly installed at the bottom of the support frame 110 for providing power to the electromagnets 211.

[0027] Furthermore, the surface of the battery 212 is electrically connected to a first wire 213 and a second wire 214, and a connection switch 215 is adapted to be installed on the surface of the second wire 214.

[0028] The connection switch 215 allows for convenient control of the energization and de-energization of the electromagnet 211, thereby controlling the magnetic attraction of the electromagnet 211 and facilitating the replacement of magnets of different specifications with the housing.

[0029] Preferably, the coils of several electromagnets 211 are connected in series, and the first wire 213 and the second wire 214 are electrically connected to the coils on the electromagnets 211 respectively.

[0030] Furthermore, the heat dissipation component 220 includes a rebound airbag 221 fixedly installed on the top of the support frame 110 and communicating with the interior of the support platform 130, a plurality of communicating grooves 222 formed on the surface of the support platform 130 for airflow, a bent rod 223 fixedly installed on the surface of the press fixture body 120, and a pressing plate 224 fixedly installed at the end of the bent rod 223 for compressing the rebound airbag 221.

[0031] Specifically, a filter frame 225 is fixedly installed on the surface of the support platform 130 and on the side near the connecting groove 222, and a filter screen is provided inside the filter frame 225.

[0032] The cooperation between the filter frame 225 and the filter screen prevents dust in the air from entering the interior of the support platform 130 when the connecting groove 222 is drawing in air, thus avoiding dust adhering to the surface of the electromagnet 211 and affecting its performance.

[0033] Furthermore, the electromagnets 211 are arranged in a linear array, and the top of the support platform 130 is provided with several reserved slots for use with the electromagnets 211.

[0034] In use: When pressing magnets of different sizes, different magnet mounting shells are required. Power off electromagnet 211 by connecting switch 215 to make electromagnet 211 non-magnetic. Remove the mounting shell located on top of support platform 130 and replace it with a matching mounting shell. Place this shell on the designated location on support platform 130. Power on electromagnet 211 again by connecting switch 215. At this time, electromagnet 211 will attract the mounting shell to the surface of support platform 130, thus limiting the mounting shell.

[0035] The bent rod 223 is fixedly installed on the lifting component of the pressing fixture body 120. When the pressing fixture body 120 presses in the magnet, the pressing fixture body 120 moves downward and drives the bent rod 223 to move. The bent rod 223 drives the pressing plate 224 to move downward, thereby pressing the pressing plate 224 against the rebound airbag 221, blowing the air inside the rebound airbag 221 into the support platform 130. The air inside the support platform 130 is then discharged through the connecting groove 222. When the pressing fixture... After the main body 120 presses the magnets, it will drive the bent rod 223 and the pressing plate 224 to move upward. When the pressing plate 224 disengages from the rebound airbag 221, the air inside the support platform 130 will be drawn back into the rebound airbag 221 under the rebound action of the rebound airbag 221. The external air will then enter the interior of the support platform 130 through the connecting groove 222, so as to achieve the purpose of air exchange inside the support platform 130, thereby playing a role in heat dissipation for the electromagnet 211.

[0036] The above description is merely a preferred embodiment of the present utility model and is illustrative rather than restrictive. Those skilled in the art will understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present utility model, all of which will fall within the protection scope of the present utility model.
