Technical Field

[0001] This utility model relates to the field of grinding wheel technology, specifically to a grinding wheel with a protective mechanism. Background Technology

[0002] A grinding wheel machine is a common piece of equipment used to sharpen various cutting tools and other tools. It is also used for grinding, deburring, and cleaning small parts. It mainly consists of a base, grinding wheel, electric motor or other power source, bracket, protective cover, and water supply. Grinding wheel machines can be categorized into handheld, vertical, suspended, and benchtop types. For example:

[0003] The grinding wheel machine described in application number CN201210463858.2 has an open structure in the grinding wheel part without protective components. As a result, during use, the friction between the grinding wheel and the workpiece generates a large amount of debris. When the grinding wheel rotates at high speed, the debris is accelerated and thrown away, posing a certain safety hazard to the surrounding operators. Utility Model Content

[0004] The purpose of this utility model is to provide a grinding wheel machine with a protective mechanism to solve the problem that the grinding wheel part of the existing equipment on the market does not have a protective component and the whole is an open structure, which causes a large amount of debris to be generated during use due to friction between the grinding wheel and the workpiece. When the grinding wheel rotates at high speed, the debris is accelerated and thrown away, which poses a certain safety hazard to the surrounding operators.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding wheel machine with a protective mechanism, comprising a support frame, a protective cover, a material rack, a drive module, and a fixing block;

[0006] The support frame is equipped with locking bolts on its side, and the locking bolts are equipped with drive rockers. The drive rockers are equipped with drive gear rings, synchronous gears, first connecting rods and second connecting rods on their left side, and a fixing block is provided on the left side of the drive rockers. The second connecting rods are equipped with second guide rods on their left side, and a guide bracket is installed above the second guide rods. The guide brackets are equipped with first guide rods at their bottom, and a drive module, a safety guard, a grinding wheel and a control switch are provided above the guide brackets. The drive module is equipped with a protective cover on its side.

[0007] As a preferred technical solution of this utility model, the bottom of the support frame is a trapezoidal structure, and the support frame as a whole is hollowed out. The right side of the support frame is rotatably connected to the drive rocker arm, and the left side of the drive rocker arm is a gear structure.

[0008] By adopting the above technical solution, the equipment can increase the contact area with the ground by making the bottom of the support frame trapezoidal, thus ensuring sufficient stability. The support frame is designed with a hollow structure, which can minimize the weight of the equipment. The right side of the support frame is connected to the drive rocker, which is more ergonomic and improves operating efficiency.

[0009] As a preferred technical solution of this utility model, the bottom of the drive rocker arm is engaged with a drive gear ring, the drive gear ring is fitted on the support frame, and a locking bolt is threadedly connected to the center position of the support frame. The locking bolt has a T-shaped structure, and the right side of the locking bolt has a threaded structure.

[0010] Using the above technical solution, the device uses a T-shaped locking bolt on the side of the drive gear ring to apply pressure and fix the drive gear ring, thereby achieving brake locking of the drive gear ring.

[0011] As a preferred technical solution of this utility model, the upper surface of the drive gear ring is meshed with a synchronous gear, and there are three synchronous gears in total, which are evenly distributed in a circle with the drive rocker arm. The inner side of the synchronous gear is rotatably connected to a fixed block, and the lower surface of the fixed block is fixedly connected to a support frame.

[0012] By adopting the above technical solution, the device uses three synchronous gears that are evenly distributed in a circle with the drive rocker arm. Under the action of the drive gear ring, the synchronous gears can be driven to rotate at a uniform speed simultaneously, which can maximize the guarantee of the device's operating accuracy.

[0013] As a preferred embodiment of this utility model, the inner side of the synchronous gear is fixedly connected to a first connecting rod, and a second connecting rod is rotatably connected above the first connecting rod, and the second connecting rod is rotatably connected to the first guide rod;

[0014] By adopting the above technical solution, the device can achieve up-and-down reciprocating operation by rotating the second link above the first link and rotating the first link in a cyclical manner.

[0015] As a preferred technical solution of this utility model, a guide bracket is fixedly connected to the upper surface of the first guide rod, the first guide rod is slidably connected to the side of the guide bracket, the first guide rod is vertically fixed at the diagonal position of the support frame, a guide cover is fixedly connected above the guide bracket, and a drive module and a control switch are fixedly connected above the center line of the guide cover, and the drive module has a built-in drive motor.

[0016] By adopting the above technical solution, the device can play a clamping and guiding role by vertically fixing the first guide rod at the diagonal position of the support frame, and fixing the guide cover above the guide bracket. This prevents the guide bracket and the support frame from shifting during lifting.

[0017] As a preferred technical solution of this utility model, the drive module is fixedly connected to both sides of the protective cover, the grinding wheel is rotatably connected inside the protective cover, and the protective cover is rotatably connected to the top of the protective cover. The material rack is bolted to the opening position on the side of the protective cover, and the material rack has a trapezoidal structure.

[0018] By adopting the above technical solution, the equipment can provide good protection for operators during use by rotating and connecting a safety guard above the protective cover. The trapezoidal structure of the material rack can provide sufficient space while ensuring support, and the threaded connection can ensure convenient replacement and improve the overall service life of the equipment.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] 1. The device features a trapezoidal bottom support frame, which increases the contact area with the ground to ensure sufficient stability. The hollow design of the support frame minimizes the weight of the device. The rotating drive rocker on the right side of the support frame is more ergonomic and improves operating efficiency.

[0021] 2. This device uses T-shaped locking bolts on the side of the drive gear ring to apply pressure and fix the drive gear ring in place, thus achieving brake locking of the drive gear ring.

[0022] 3. The device uses three synchronous gears that are evenly distributed in a circle with the drive rocker arm. Under the action of the drive gear ring, the synchronous gears can be driven to rotate at the same speed simultaneously, which can maximize the accuracy of the device operation.

[0023] 4. The device is connected to the second link by rotating above the first link, which allows the device to move up and down reciprocally during the cyclic rotation of the first link;
