Description

Technical Field

[0001] This utility model relates to the field of internal hole grinding technology, specifically to a device for polishing and grinding the internal holes of parts. Background Technology

[0002] Grooves are commonly used in machines and equipment to create internal holes in components. For example, grooves are often placed in the internal holes of bearing housings to house sealing rings for sealing lubricating oil. When the surface finish requirement for the grooves in the internal holes of components is not high, machining is usually employed. However, when a high surface finish is required, the surface of the groove at the assembly point needs to be carefully polished. Existing polishing devices lack a cooling function, and the polishing head is often used continuously, causing its temperature to rise rapidly over time, thus reducing its lifespan. Therefore, a polishing and grinding device for the internal holes of components is proposed. Utility Model Content

[0003] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows:

[0005] A polishing and grinding device for the inner hole of a component includes a grinding mechanism and a positioning mechanism. The grinding mechanism includes a fixed frame, a fixed plate connected to the bottom end of the fixed frame, a motor disposed in the middle of the fixed plate, a rotating shaft connected to the output end of the motor, a grinding head connected to the bottom end of the rotating shaft, and a grinding sleeve surrounding the middle of the grinding head. A stabilizing component is installed at the center of the bottom of the fixed plate, and an angle steel is installed on the side of the stabilizing component. Cooling pipes are inserted into both sides of the fixed plate, and the cooling pipes are located above the angle steel. The positioning mechanism includes a threaded rod threaded to the side of the fixed plate, a connecting rod inserted into the bottom end of the threaded rod, a positioning plate connected to the bottom end of the connecting rod, and a spring sleeved on the top end of the connecting rod.

[0006] Preferably, the number of angle steels is four, and each of the four angle steels has a slot.

[0007] Preferably, the number of cooling pipes is two sets, and the two sets of cooling pipes are symmetrically arranged on both sides of the stabilizer.

[0008] Preferably, a turntable is provided at the top end of the threaded rod, and the top end of the threaded rod is telescopically engaged with the top end of the connecting rod.

[0009] Preferably, the top end of the spring is connected to the bottom end of the threaded rod, and the bottom end of the spring abuts against the middle of the connecting rod.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0011] In this invention, an angle steel is used to press the top of the grinding head, thereby ensuring that the grinding head will not tilt when rotating, improving the reliability of the grinding and polishing process. At the same time, slots are made in the angle steel so that the coolant sprayed from the cooling pipe can quickly contact the grinding head, achieving rapid cooling of the grinding head. The angle steel also guides the coolant to the component body, thereby cooling the component and improving the practicality of the device. Attached Figure Description

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0018] The following describes, with reference to the accompanying drawings, some embodiments of a component inner hole polishing and grinding device provided by this utility model.

[0019] Example:

[0020] Combination Figure 1-2As shown, this utility model provides a polishing and grinding device for the inner hole of a component, including a grinding mechanism and a positioning mechanism. The grinding mechanism includes a fixed frame 110, a fixed plate 120 connected to the bottom end of the fixed frame 110, a motor 130 disposed in the middle of the fixed plate 120, a rotating shaft 150 connected to the output end of the motor 130, a grinding head 160 connected to the bottom end of the rotating shaft 150, and a grinding sleeve 170 surrounding the middle of the grinding head 160. A stabilizing component 140 is installed at the center of the bottom of the fixed plate 120, and four angle steels 180 are installed on the sides of the stabilizing component 140. Each of the four angle steels 180 has a slot, and slots are inserted into the two sides of the fixed plate 120. A cooling pipe 190 is connected, and the cooling pipe 190 is located above the angle steel 180. There are two sets of cooling pipes 190, which are symmetrically arranged on both sides of the stabilizer 140. The positioning mechanism includes a threaded rod 210 threaded to the side of the fixing plate 120, a connecting rod 220 inserted into the bottom end of the threaded rod 210, a positioning plate 240 connected to the bottom end of the connecting rod 220, and a spring 230 sleeved on the top end of the connecting rod 220. A turntable is provided at the top end of the threaded rod 210. The threaded rod 210 and the top end of the connecting rod 220 are telescopically engaged. The top end of the spring 230 is connected to the bottom end of the threaded rod 210, and the bottom end of the spring 230 abuts against the middle of the connecting rod 220.

[0021] Specifically, by utilizing the slots on the angle steel 180, the coolant sprayed from the cooling pipe 190 can be evenly sprayed onto the grinding head 160, achieving comprehensive cooling. At the same time, the position of the grinding head 160 can be limited to prevent it from tilting and affecting the grinding effect.

[0022] Additionally, a spring 230 is connected to the top of the connecting rod 220 so that when the positioning plate 240 contacts the component, once the lifting device continues to descend, the connecting rod 220 can retract into the threaded rod 210, preventing the positioning plate 240 from affecting the grinding of the grinding sleeve 170 and improving the reliability of the device.

[0023] The working principle and usage process of this utility model are as follows: First, the device is fixed on a lifting structure using the fixing frame 110. Then, the top end of the cooling pipe 190 is connected to the coolant. The device is started, and the lifting device is used to press down the fixing frame 110, so that the positioning plate 240 is pressed on the part, thus completing the fixation. At the same time, the grinding sleeve 170 contacts the inner hole of the part and begins grinding. During the grinding process, the cooling pipe 190 sprays coolant onto the angle steel 180, which spreads the coolant evenly on the part, achieving overall cooling. Finally, the processed part is taken out.

[0024] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
