Description

Technical Field

[0001] The utility model relates to the technical field of bolt processing, in particular to the technical field of a polishing device for bolt processing. Background Art

[0002] A bolt is a mechanical part, a cylindrical threaded fastener that is matched with a nut. It is a type of fastener consisting of a head and a screw (a cylinder with external threads). It needs to be matched with a nut to fasten and connect two parts with through holes.

[0003] After the bolts are produced, they need to be polished to remove burrs for easy use. However, the existing bolt polishing device does not have a fixing device for the bolts. During the polishing process, the bolts shake, resulting in an unsatisfactory polishing effect, and the height of the polishing machine cannot be adjusted.

[0004] To solve the problems raised in the background technology, for example, application number CN202020385660.7 discloses a bolt polishing device, including a supporting base, a polishing table, a fixed card seat, a cavity, a telescopic spring, a card block, a transmission rope, a pulley, a fixed sleeve rod, a telescopic rod, a connecting plate, a fixed rod, a polishing plate, a polishing motor, and a polishing sleeve head. A polishing table is fixed to the left end above the supporting base, and a fixed card seat is fixed to the upper end of the polishing table. The bolt is fixed by the fixed card seat to prevent shaking during the polishing of the bolt, resulting in an unsatisfactory polishing effect. The bolt is placed in the fixed card seat, and the bolt compresses the transmission rope in the fixed card seat toward the bottom of the fixed card seat. The transmission rope pulls the card block out of the cavity horizontally. The card blocks in the cavities at both ends are pulled close to each other under the pull of the transmission rope. When the bolt compresses the transmission rope to the bottom, the card blocks at both ends are closed to fix the bolt. The polishing position of the polishing sleeve head and the bolt is adjusted by adjusting the height of the telescopic rod. However, the structure still has the following defects:

[0005] During the polishing process, the polishing disc needs to constantly rub against the bolt, which will cause the polishing disc body to generate a certain temperature. The high temperature is transmitted to the bolt through the polishing disc, causing deformation and damage on the bolt surface, affecting the appearance integrity of the bolt, seriously affecting the bolt's factory rate, and low practicality.

[0006] To solve the problems raised in the above technologies, for example, Patent Application No. CN202023269161.0 discloses a bolt polishing machine, including an operating table. A movable seat is fixedly installed on the top of the operating table. One end of the movable seat is movably clamped with a mounting frame. A polishing machine cover is fixedly installed on the inner surface of the mounting frame. A polishing disc is movably clamped inside the polishing machine cover. A water-absorbing sponge is inlaid inside the polishing disc. At the same time, a coolant is sprayed onto the water-absorbing sponge through a spray head. When the polishing disc rotates, the coolant inside the water-absorbing sponge is thrown out by centrifugal force and evenly distributed on the outer surface of the polishing disc to cool the polishing disc, thereby preventing the bolt from being damaged due to high temperature during the processing and improving the passing rate of the bolts, with stronger practicability. However, this structure still has the following defects:

[0007] Although this structure sprays coolant onto the water-absorbing sponge through a spray head to reduce the surface temperature of the polishing disc, when the device grinds and polishes the surface of the bolt, the polishing disc cannot move. The polishing disc can only grind and polish a part of the bolt, and its degree of automation is not high. It is necessary to manually adjust the polishing direction of the polishing disc, thereby reducing the grinding and polishing efficiency of the bolt. Summary of the Invention

An L-shaped support plate is arranged on one side of the upper end surface of the base. A cooling mechanism for cooling the polishing wheel is arranged on the upper end surface of the L-shaped support plate.

[0010] Preferably, the clamping mechanism includes fixing blocks, rotating rods, rotating motors, moving blocks, L-shaped support rods, and clamping sleeves.

After the bolt to be processed is fixed by the clamping mechanism, the electric telescopic rod is controlled by an external power source, so that the electric telescopic rod extends forward, thereby driving the polishing wheel to move forward until the polishing wheel is attached to the outer surface of the bolt. Then the driving motor is started, and the driving motor drives the polishing wheel to rotate, so that the polishing wheel polishes the surface of the bolt. Then the electric slider is started, so that the electric slider can move annularly on the circular electric slide rail, thereby driving the polishing wheel to polish around the bolt, and further polishing different surfaces of the bolt, making the polishing of the bolt uniform, thus improving the processing quality and processing efficiency, and solving the problems that the polishing disc cannot move, the polishing disc can only polish a part of the bolt, and its automation degree is not high.

The clamping mechanism 11 includes a fixed block 111, a rotating rod 112, a rotating motor 113, a moving block 114, an L-shaped support rod 115, and a clamping sleeve 116. The fixed blocks 111 are symmetrically arranged. A rotating rod 112 is rotatably arranged between the fixed blocks 111. A rotating motor 113 is arranged on the outer side wall of the fixed block 111. The output end of the rotating motor 113 penetrates the side wall of the fixed block 111 and is connected to the rotating rod 112.

First, place the bottom of the bolt to be processed between the two clamping sleeves 116. Then start the rotating motor 113. The rotating motor 113 drives the rotating rod 112 to rotate. The rotating rod 112 drives the two moving blocks 114 to approach each other, and further drives the two clamping sleeves 116 to approach each other until the clamping sleeves 116 are attached to both sides of the outer wall of the bolt.

[0025] The working process of the present utility model:

[0026] During the working process of a polishing device for bolt processing according to the present utility model, first, the bottom of the bolt to be processed is placed between two clamping sleeves 116.

The rotation rod 112 drives two moving blocks 114 to approach each other, and further drives two clamping sleeves 116 to approach each other until the clamping sleeves 116 are attached to both sides of the outer wall of the bolt. Then, the clamping sleeves 116 are driven by the rotation of the rotation rod 112 to clamp the bolt. After the bolt is fixed, the electric telescopic rod 7 is controlled by an external power source, so that the electric telescopic rod 7 extends forward, and further drives the polishing wheel 10 to move forward until the polishing wheel 10 is attached to the outer surface of the bolt. Then, the driving motor 9 is started. The driving motor 9 drives the polishing wheel 10 to rotate, so that the polishing wheel 10 polishes the surface of the bolt. Then, the electric slider 4 is started, so that the electric slider 4 can move in a circular motion on the circular electric slide rail 3, and further drives the polishing wheel 10 to polish around the bolt, and then polishes different surfaces of the bolt, so that the polishing of the bolt is uniform, thereby improving the processing quality and processing efficiency. When the surface temperature of the polishing wheel 10 is relatively high after long-term work, the liquid extraction pump 134 is started. The liquid extraction pump 134 extracts the coolant in the cooling tank 133 and transports it to the liquid spraying head 135 through a pipeline. When the polishing wheel 10 passes under the liquid spraying head 135, the liquid spraying head 135 sprays the coolant outwards to cool the polishing wheel 10, avoiding damage to the surface of the bolt caused by excessive temperature.
