Description

Technical Field

[0001] The utility model relates to the field of synchronous grinding tool structure, in particular to a multi-level synchronous grinding tool structure. Background Art

[0002] The filter cloth is used at the air inlet of the hair dryer to effectively filter particles, hair, etc., to prevent debris from entering the hair dryer motor and causing damage to the internal motor. Since the waterproof and oil-proof coating on the surface of the filter cloth is very smooth, the bonding rate with the plastic particles during the injection molding process is low, causing the filter to separate from the plastic part after injection molding, causing impurities to enter the motor through the detached gap. Therefore, the surface of the filter needs to be polished to increase the roughness of the filter surface, thereby increasing the bonding rate of the filter injection molding and ensuring sealing reliability.

[0003] However, on the one hand, due to the steps of the filter screen, the current grinding tool cannot grind to the upper and lower step surfaces at one time, so the grinding has to be divided into two steps, which increases the extra labor cost and the defective rate is relatively increased; on the other hand, after testing, the grinding particles of the existing conventional sandpaper have been ground flat after being used more than 4 times, resulting in a high frequency of sandpaper replacement, which increases the cost of grinding and needs improvement. Utility Model Content

[0004] The utility model aims to provide a multi-level synchronous grinding tool structure, which has the advantages of simple structure and high grinding efficiency.

[0005] The above-mentioned technical purpose of the utility model is achieved through the following technical solutions: a multi-level synchronous grinding tooling structure, including a fixed seat and a grinding seat fixedly connected to the fixed seat for placing a filter screen; a pressure plate is slidably connected to the grinding seat along the vertical direction based on a spring guide screw, and a toggle clamp is fixedly provided on the fixed seat for applying pressure to the pressure plate so as to press and fix the filter screen on the grinding seat; a horizontal sliding seat is slidably connected to the fixed seat based on a sliding assembly, and a horizontal adjustment platform is fixedly connected to the horizontal sliding seat based on an adjustment assembly, and at least one mounting seat is fixedly connected to the horizontal adjustment platform, and the mounting seat is provided with a grinding wheel shaft that is staggered front and back and up and down for grinding the stepped surface of the filter screen.

[0006] The utility model is further configured as follows: the adjustment component includes a plurality of adjustment screws that evenly penetrate the horizontal adjustment platform and are locked and fixedly connected to the horizontal sliding seat; a spring is sleeved and connected on the adjustment screw, and two ends of the spring are respectively abutted between the horizontal sliding seat and the horizontal adjustment platform.

[0007] The utility model is further configured as follows: the sliding assembly comprises a slide rail fixedly connected to the fixed seat along a direction parallel to the grinding seat and a sliding block fixedly connected to the horizontal sliding seat.

[0008] The utility model is further configured as follows: a sliding shaft is coaxially fixedly provided on the grinding wheel shaft, a sliding groove for sliding the sliding shaft is opened on the mounting seat, a clearance is fitted between the sliding shaft and the sliding groove, and a damping screw for pressurizing the sliding shaft in the sliding groove is provided on the mounting seat.

[0009] The utility model is further configured as follows: the mounting seat can be raised and lowered and adjusted on the horizontal adjustment platform based on locking of the limit screw.

[0010] The utility model is further configured as follows: two groups of mounting seats are fixedly connected to the horizontal adjustment platform.

[0011] The utility model is further configured as follows: a horizontal push handle is fixedly connected to the horizontal adjustment platform.

[0012] In summary, the utility model has the following beneficial effects:

[0013] 1. A grinding seat is set on the fixed seat, and a pressure plate is set on the grinding seat based on a spring guide screw. At the same time, a toggle clamp is set on the fixed seat. The filter to be polished is placed between the pressure plate and the grinding seat and positioned on one side. The toggle clamp applies pressure to the pressure plate to press and fix the filter on the grinding seat. After the polishing is completed, the toggle clamp is opened, and the spring guide screw drives the pressure plate to automatically lift up, so that the filter can be quickly pulled out and the filter can be turned and pressed again, so that the other sides of the filter can be polished. A horizontal sliding seat is set on the fixed seat based on the sliding assembly, and an adjustment assembly is set on the horizontal sliding seat. A horizontal adjustment table is fixedly arranged, and a push handle is fixedly connected to the horizontal adjustment table. A mounting seat is fixedly arranged on the horizontal adjustment table, and grinding wheel shafts are staggered front and back and up and down on the mounting seat. The horizontal sliding seat and the horizontal adjustment table are driven to slide by pushing the push handle, and the grinding wheel shaft grinds the step surface of the filter screen at the same time. The structure is simple, and the grinding efficiency is improved. In addition, due to the arrangement of the adjustment component, the friction between the grinding wheel shaft and the filter screen can be kept constant, which reduces the damage to the grinding wheel shaft caused by the difference in the thickness of the filter screen, reduces the grinding cost and improves the grinding efficiency.

[0014] 2. A sliding shaft is set on the grinding wheel shaft and a sliding groove is opened on the mounting seat, and a clearance fit is set between the sliding shaft and the sliding groove, and a damping screw for pressurizing the sliding shaft in the sliding groove is set on the mounting seat. Since there is a tolerance in the thickness of the filter mesh, when the thickness of the filter mesh is equal to or less than the set value, there is sliding friction between the grinding wheel group and the filter mesh. When the thickness of the filter mesh exceeds the set value, the gap between the grinding wheel group and the filter mesh becomes smaller and the sliding friction increases. At this time, the friction force will overcome the damping and change from sliding friction to rolling friction at a low speed, thereby reducing the possibility of cracking of the filter mesh and improving the grinding effect.

In this embodiment, two sets of mounting seats 10 are fixedly connected to the horizontal adjustment platform 9, and the grinding efficiency is further improved by the two sets of grinding wheel shafts 11.

[0022] refer to Figure 1 to Figure 2 Specifically, the adjustment component 8 includes a plurality of adjustment screws 81 that evenly penetrate the horizontal adjustment platform 9 and are locked and fixedly connected to the horizontal sliding seat 7. A spring 82 is sleeved and connected to the adjustment screw 81. The two ends of the spring 82 are respectively abutted between the horizontal sliding seat 7 and the horizontal adjustment platform 9.
