Description

Technical Field

[0001] The invention relates to a surface treatment device for a bonded abrasive tool, in particular to a surface treatment device for a bonded abrasive tool applied in the field of surface treatment of a bonded abrasive tool. Background Art

[0002] Bonded abrasives are tools made of abrasives and binders with a certain shape and grinding ability. Bonded abrasives usually use four major types of binders: ceramics, resins, rubber, and magnesia. When processing bonded abrasives, in order to meet certain special processing requirements, certain fillers such as sulfur or paraffin are impregnated in the pores of the abrasives to improve the performance of the abrasives. During the processing of bonded abrasives, the abrasive particles on the surface need to be ground, and more debris will be generated in the process. The debris needs to be handled in time to ensure low dust in the processing environment, thereby protecting the health of the operators.

[0003] The specification of Chinese invention patent CN202410315781.7 discloses a surface processing device for a planetary reducer with a protective function. By opening multiple grooves under the grinding disc and cooperating with the airflow generated by the air pump, the generated debris can be collected in time. At the same time, the circular ring on the outside of the grinding disc is used to limit the movement range of the debris to ensure that most of the debris is collected.

[0004] During the grinding operation, the existing surface treatment device usually uses suction operation to absorb mobile phone debris. However, as the suction operation continues, the suction interception filter will become blocked, affecting the subsequent suction collection effect. An additional cleaning structure will be required to ensure the smoothness of the interception filter surface. Summary of the invention

[0008] An interception filter is installed inside the suction rack, an exhaust pipe with an L-shaped cross-section is installed through the bottom of the suction rack, and an aggregate frame is installed below the suction rack.

[0009] In the above-mentioned surface treatment equipment for fixed abrasive tools, the debris generated during the grinding process is treated in a targeted manner through the flip unit and the suction frame, and the debris on the surface of the interception filter is cleaned conveniently and efficiently while ensuring the suction capacity of the interception filter.

[0010] As a further improvement of the present application, the tail end of the exhaust pipe is upward, and the tail end of the exhaust pipe is located at the end of the follower plate away from the return spring.

[0011] As a further improvement of the present application, the reducing rod includes region No. 1, a bevel gear No. 1 is arranged on the surface of region No. 1, the end of region No. 1 away from the suction frame is connected to region No. 2 with decreasing diameter, and the end of region No. 2 away from the suction frame is connected to region No. 3 whose tail end is rotatably connected to the surface of the fixed disk.

[0031] Two implementation modes of the present application are described in detail below with reference to the accompanying drawings.

[0032] The first implementation method:

[0033] Figure 1-3 A surface treatment device for bonded abrasive tools is shown, comprising an operating table 1, a notch is provided on the top of the operating table 1, a cover frame is installed on the outer side of the top of the notch, a grinding retaining frame 2 with a plurality of circular holes on the bottom is embedded and installed inside the notch, a sleeve shaft 3 is rotatably connected to the center of the grinding retaining frame 2, a driving motor 4 is installed on the surface of the grinding retaining frame 2, and the output end of the driving motor 4 is connected to the bottom of the sleeve shaft 3 through a conveyor belt 41, and symmetrically arranged turning units 6 and a suction frame 7 with a circular cross section located between the two turning units 6 are installed below the operating table 1, and the suction frame 7 is located directly below the notch;

[0034] Figure 3-4 and Figure 6 As shown, the flip unit 6 includes a fixed plate 61 fixedly connected to the bottom surface of the operating table 1, a reset spring 62 is connected to the surface of the fixed plate 61, a follower plate 63 is connected to the tail end of the reset spring 62, a through hole is provided inside the follower plate 63, a reducing rod 64 which passes through the inside of the follower plate 63 is rotatably connected to the surface of the fixed plate 61, the tail end of the reducing rod 64 is connected to the surface of the suction frame 7, a first bevel gear 66 is sleeved on the surface of the reducing rod 64, a rack 65 is connected to the surface of the follower plate 63 on the side away from the reset spring 62, a second bevel gear 67 is meshedly connected to the bottom of the first bevel gear 66, a rotating gear 68 meshed with the rack 65 is arranged below the second bevel gear 67, and the rotating gear 68 is connected to the second bevel gear 67 through a connecting rod.

[0035] An interception filter screen 71 is installed inside the suction rack 7 , an exhaust pipe 72 with an L-shaped cross section is installed through the bottom of the suction rack 7 , and a collection frame 5 is installed below the suction rack 7 .

[0036] The suction rack 7 is in a downward position when not started, and the follower plate 63 moves in a direction close to the suction rack 7 when the suction rack 7 is started, and the diameter-changing rod 64 rotates 180 degrees when the follower plate 63 moves to the position of the second bevel gear 67 .

[0037] Specifically, when the present invention is used to perform surface treatment on a bonded abrasive tool, the abrasive tool to be treated needs to be sleeved onto the surface of the sleeve shaft 3, and then the drive motor 4 is started. Under the action of the conveyor belt 41, the sleeve shaft 3 and the abrasive tool on the surface are driven to rotate, and the corresponding grinding piece can be matched to perform the corresponding surface treatment operation;

[0038] Before grinding, the suction frame 7 is started, and the suction wind force generated is then discharged through the exhaust pipe 72. Since the exhaust pipe 72 is located on the side of the follower plate 63 close to the suction frame 7, the discharged wind force makes the gas flow rate on the side of the follower plate 63 close to the suction frame 7 greater than the other side, and then the air pressure force can drive the follower plate 63 to move on the surface of the reducing rod 64 and approach the suction frame 7. In this process, the rack 65 moves and drives the rotating gear 68 to rotate, and drives the second bevel gear 67 to rotate. Under the meshing action, the first bevel gear 66 drives the reducing rod 64 to rotate until the through hole in the follower plate 63 is engaged with the position of the second area 642 close to the first area 641, that is, the follower plate 63 moves to the position of the second bevel gear 67. Due to the interception of the through hole and the second area 642 and the interception effect of the second bevel gear 67, the reducing rod 64 and the suction frame 7 can be rotated 180 degrees, so that the suction frame 7, which is in a downward flipped state in the initial state, faces upward (such as Figure 7 As shown), and then the debris in the grinding baffle 2 is sucked and transferred to the surface of the interception filter 71 by means of suction wind;

[0039] After the surface treatment of a single mold is completed, the suction rack 7 is closed. At this time, due to the cessation of wind discharge, the follower plate 63 is driven to move away from the suction rack 7 under the action of the reset spring 62. At this time, the rack 65 moves in the opposite direction and indirectly drives the diameter-changing rod 64 to rotate in the opposite direction under the meshing action until it returns to the original downward flipping state, so that the debris intercepted and accumulated on the surface of the interception filter 71 can fall into the interior of the aggregate frame 5 (such as Figure 8 shown).

[0040] Through the above operation, the debris can be cleaned after the surface treatment of a single mold, so as to avoid the long-term accumulation of debris. The suction unobstructedness of the interception filter 71 can be ensured by the discharge of wind force during suction.

[0041] The tail end of the exhaust pipe 72 faces upward, and is located at an end of the follower plate 63 that is away from the return spring 62 .

[0042] Specifically, the exhaust pipe 72 is designed to discharge the wind force discharged from the suction frame 7 upward, so that when the wind force is discharged, the difference in gas flow rate can be used to provide power for the movement of the follower plate 63.

[0043] Figure 5 It is shown that the reducing rod 64 includes a No. 1 region 641, a No. 1 bevel gear 66 is arranged on the surface of the No. 1 region 641, the end of the No. 1 region 641 away from the suction frame 7 is connected to the No. 2 region 642 with decreasing diameter, and the end of the No. 2 region 642 away from the suction frame 7 is connected to the No. 3 region 643 with the tail end rotatably connected to the surface of the fixed plate 61.

[0044] The diameter of the through hole in the follower plate 63 is larger than the diameter of the third area 643 and smaller than the diameter of the first area 641 , and the diameter of the reducing rod 64 is smaller than the diameter of the return spring 62 .

[0045] Specifically, since the reducing rod 64 is composed of three parts, the No. 1 region 641 is mainly used to install and arrange the No. 1 bevel gear 66, the No. 2 region 642 mainly provides a rod body area with decreasing diameter so that the follower plate 63 can move closer and complete the effect of clamping and intercepting, and the No. 3 region 643 is mainly used to connect the No. 2 region 642 and the fixed plate 61.

[0046] The rack 65 is located below the suction frame 7 , and the rack 65 and the exhaust pipe 72 are staggered.

[0047] Specifically, the rack 65 will not be intercepted by the suction frame 7 when moving, thereby ensuring the smoothness of the rack 65 when moving.

[0048] The second implementation method:

[0049] Fig. 9 It is shown that a plurality of extrusion springs 73 are installed on the inner wall of the suction frame 7 , and a collision ball 74 is connected to the tail end of the extrusion spring 73 .

[0050] Fig.10 It is shown that when the suction rack 7 is in the started state, the interception filter 71 is located above the impact ball 74, and the diameter of the impact ball 74 is larger than the diameter of the exhaust pipe 72, and the interior of the impact ball 74 is provided with a plurality of penetrating channels.

[0051] Different from the first embodiment, this embodiment mainly performs a shaking process on the intercepting filter screen 71 in the unloading state after being turned over to promote the adequacy of unloading.

[0052] Specifically, Fig.11As shown, after the suction rack 7 is closed, the suction rack 7 flips downward, and under the action of gravity, the impact ball 74 impacts the interception filter 71 downward, so that the debris blocked in the interception filter 71 can be shaken out and cleaned, thereby enhancing the cleaning effect. In addition, when the suction rack 7 is started, the impact ball 74 may be blocked at the pipe mouth position of the exhaust pipe 72 under the action of the suction wind force, affecting the exhaust smoothness of the exhaust pipe 72. Therefore, a through channel is designed inside the impact ball 74, so that even if the impact ball 74 is blocked at the pipe mouth position, the exhaust purpose can be achieved.

[0053] In summary, when the present application is working, through the flip unit 6 and the suction frame 7, when suctioning and collecting dust, the air flow velocity on both sides of the follower plate 63 can be different by virtue of the suction wind force of the suction frame 7, and then under the Bernoulli phenomenon, the follower plate 63 can autonomously approach the suction frame 7 when the suction frame 7 is started, and when it moves to the position of the second bevel gear 67, the through hole in the follower plate 63 can be snapped onto the surface of the second area 642, and the reducing rod 64 is limited after the suction frame 7 is flipped 180 degrees, so that the suction frame 7 can perform suction processing in the positive direction, satisfying the normal suction operation of the suction frame 7, and after the suction frame 7 is closed, the suction frame 7 flips and resets to dump the debris on the surface of the interception filter 71 into the aggregate frame 5, and in this process, the impact ball 74 is used to promote the cleaning degree of the debris on the surface of the interception filter 71.

[0054] In view of current practical needs, the above-mentioned implementation mode adopted in this application is not limited to the scope of protection. Various changes made within the knowledge scope of technical personnel in this field without departing from the concept of this application still fall within the scope of protection of the present invention.
