[0002] A resin grinding wheel is made of resin, has high strength, and is applied to cutting discs, double-sided grinding wheels, heavy-load grinding wheels, polishing wheels, etc. It has a certain elasticity, low heat resistance, good self-sharpening property, is simple to manufacture, and has a short process cycle; it is widely used in rough grinding, snag grinding, cutting, and free grinding, such as grinding steel ingots and deburring castings.

[0003] For example, a resin grinding wheel with the application number 202223236736.8 has a reasonable structure. Through the setting of the limiting component, it is convenient to disassemble the resin grinding wheel body from the grinding wheel. After the replacement is completed, drag the grinding wheel to drive the fixing rod to insert into the through hole until the grinding wheel fits with the resin grinding wheel body. Release the pull block, and the slider drives the limiting rod to return to its original position under the action of the spring and engages with the clamping groove to limit and fix the fixing rod, which is convenient for the disassembly and installation of the resin grinding wheel body and the grinding wheel. However, after the grinding wheel reaches its service life, its thickness will become thinner, and it is difficult for the operator to timely adjust the appropriate alarm threshold according to the grinding wheels of different thicknesses.

[0004] Therefore, in view of this, research and improvement are carried out on the existing structural deficiencies, and a large-size high-speed resin heavy-load steel billet grinding wheel is proposed. Content of the Utility Model

[0006] To achieve the above purpose, the utility model provides the following technical solution: A large-size high-speed resin heavy-load steel billet grinding wheel, including a steel billet body and a resin grinding disc arranged on the front surface of the steel billet body. An installation hole is opened on the rear surface of the steel billet body extending into the interior, and an alarm mechanism is arranged on the inner circular surface of the steel billet body.

[0007] Preferably, the alarm mechanism includes a fixed seat fixedly connected to the inner circular surface of the steel billet body. A jack is penetrated through the outer surface of the fixed seat, an alarm rod is arranged inside the jack, and a locking screw is threadedly connected to the outer surface of the fixed seat extending into the jack.

[0008] Preferably, one end of the locking screw is fixedly connected with a knob, and an anti-slip pattern is arranged on the outer circular surface of the knob.

[0011] Preferably, ventilation holes are formed by extending from the inner surface to the outer surface of the steel billet body, and the number of the ventilation holes is six.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] 1. Through the settings of the steel billet body, the resin grinding disc, the mounting holes, the warning mechanism, the fixing seat, the jack, the warning rod and the locking screw, by inserting the warning rod into the jack, when the resin grinding disc is severely worn, the warning rod will contact the outer surface of the item to be ground, and noise will be generated through friction, reminding the operator that the resin grinding disc is severely worn and needs to be replaced;

[0014] 2. Through the settings of the hook block, the clamping groove and the ventilation holes, the stability of the grinding wheel during high-speed rotation can be ensured. When the grinding wheel rotates at a high speed, the ventilation holes can improve air circulation and the heat dissipation efficiency during grinding. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0021] Such as Figure 1 , Figure 2 and Figure 4As shown in the figure, a large-sized high-speed resin heavy-duty steel billet grinding wheel includes a steel billet body 1 and a resin grinding disc 2 provided on the front surface of the steel billet body 1. An installation hole 3 is provided by extending the rear surface of the steel billet body 1 into the interior. An alarm mechanism 4 is provided on the inner circular surface of the steel billet body 1. The steel billet body 1 is a large-sized steel billet grinding wheel. The alarm mechanism 4 includes a fixed seat 41 fixedly connected to the inner circular surface of the steel billet body 1. A jack 42 is penetrated through the outer surface of the fixed seat 41. An alarm rod 43 is provided inside the jack 42. A locking screw 44 is threadedly connected to the interior of the jack 42 by extending the outer surface of the fixed seat 41. The alarm rod 43 can be made of an aluminum rod.

[0022] By adopting the above technical solution, the steel billet body 1 can be installed on the grinding machine through the installation hole 3. The resin grinding disc 2 can meet heavy-duty operations. By inserting the alarm rod 43 into the jack 42 and adjusting the extended position of the alarm rod 43, after determining the position, tighten the locking screw 44 to lock and fix the alarm rod 43. When the resin grinding disc 2 is worn to a large extent, the alarm rod 43 will contact the outer surface of the item being ground, and noise will be generated through friction to remind the operator that the resin grinding disc 2 is worn to a large extent.

[0023] As Figure 2 - Figure 3 shown in the figure, one end of the locking screw 44 is fixedly connected with a knob 441, and an anti-slip pattern is provided on the outer circular surface of the knob 441. The anti-slip pattern on the knob 441 can increase friction and facilitate the rotation of the knob 441.

[0024] Furthermore, a hook block 5 is fixedly connected to the front surface of the steel billet body 1, and the number of hook blocks 5 is six. The extended length of the front end of the alarm rod 43 should protrude from the front surface of the hook block 5.

[0025] Furthermore, a card slot 6 is provided on the rear surface of the resin grinding disc 2, and the number of card slots 6 is six.

[0026] Furthermore, a ventilation hole 7 is provided by extending the inner surface of the steel billet body 1 to the outer surface, and the number of ventilation holes 7 is six. The inner surface of the ventilation hole 7 is designed to be inclined.

[0027] Working principle: When using this large-sized high-speed resin heavy-duty steel billet grinding wheel, first, the steel billet body 1 can be installed on the grinding machine through the mounting hole 3. The resin grinding disc 2 can meet heavy-duty operations. By inserting the warning rod 43 into the jack 42 and adjusting the extended position of the warning rod 43, after determining the position, tighten the locking screw 44 to lock and fix the warning rod 43. When the resin grinding disc 2 is worn to a large extent, the warning rod 43 will contact the outer surface of the item being ground, and noise will be generated through friction to play a warning role. When installing the resin grinding disc 2, insert the hook block 5 into the inside of the card slot 6 and rotate the resin grinding disc 2 to achieve the fixing effect. When disassembling, reverse rotation can achieve the disassembly function. This is the working principle of this large-sized high-speed resin heavy-duty steel billet grinding wheel.
