Description

Technical Field

[0001] The utility model relates to the field of grinding devices, in particular to a multifunctional parts grinding platform. Background Art

[0002] In the chemical industry, during routine maintenance or overhaul of equipment, there will be some tools and tools that need to be polished, and the cutting burrs of various small plates. For example, plugs, screwdrivers, knives, small steel plates and other metal shell items have oxidized rust or burrs on their surfaces, which need to be polished. Using a single existing belt sander cannot effectively deal with such complex grinding conditions. The main reason is that when grinding the cutting burrs of the plate, the angle of the belt sander must be adjusted according to the needs at any time. The angle of the existing belt sander is not adjustable, which will cause inconvenience during grinding. At the same time, some parts have irregular surfaces, and ordinary belt sanders cannot grind them thoroughly, resulting in the need for workers to manually perform secondary grinding, which is not only inefficient but also labor-intensive. In addition, ordinary belt sanders do not have a polishing function and cannot polish some fine parts. If they rely solely on sandpaper grinding and polishing, their original structure is easily damaged. Utility Model Content

[0003] Therefore, in order to solve the above-mentioned shortcomings, the utility model provides a multifunctional parts grinding platform, which can not only quickly adjust the grinding angle, but also effectively grind parts with uneven surfaces, and at the same time can polish precision parts.

[0004] The technical solution adopted by the utility model is as follows:

DETAILED DESCRIPTION

[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0020] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a multifunctional parts grinding platform, including a frame 1 and a grinding device arranged on the frame 1, the grinding device includes a driving wheel 2, a limiting mechanism 3, a driven wheel 4, a grinding part 5 and a motor 6, the motor 6 is fixed on the frame 1, the driving wheel 2 is connected to the output shaft of the motor 6, the limiting mechanism 3 is arranged on the upper part of the frame 1, and can slide a certain angle in the circumferential direction with the driving wheel 2 as the axis, the driven wheel 4 is installed on the limiting mechanism 3, and the grinding part 5 includes a sanding belt 51 sleeved on the driving wheel 2 and the driven wheel 4 and a grinding drill bit 52 installed on the driven wheel 4.

[0021] The frame 1 is welded from stainless steel plates, including a bottom plate and a vertical plate perpendicular to the bottom plate. The motor 6 is fixed to the bottom plate of the frame 1 by fastening screws. The shaft of the driving wheel 2 is coaxially connected to the output shaft of the motor 6, and a ball bearing is provided on the vertical plate to support the shaft of the driving wheel 2 and increase the life of the motor 6. To facilitate the adjustment of the angle of the sanding belt 51, the limiting mechanism 3 needs to be able to slide a certain angle around the driving wheel 2 as the axis. The driven wheel 4 is installed on the shaft of the driven wheel 4 connected to the limiting mechanism 3, and the sanding belt 51 is sleeved between the two wheels. A drill bit mounting hole 41 is provided on the driven wheel 4 for mounting a grinding drill bit 52, which can rotate with the driven wheel 4 at the same time.

[0022] It should be noted that an arc-shaped support beam 12 with a through groove 11 is provided on the upper part of the frame 1. The plane in which the arc is located is the vertical plane of the axis of the driving wheel 2 and the center of the arc is on the axis of the driving wheel 2. The limiting mechanism 3 includes a stopper 31, an L-shaped clamping block 32 and an adjusting bolt 33. The stopper 31 is in an inverted convex shape and has a circular hole in the middle. It is downwardly installed in the through groove 11, and both sides fall on the top surface of the support beam 12. The inner side of the support end of the L-shaped clamping block 32 is tightly against the outer side of the support beam 12, and a hole with an internal thread on the connecting end that matches the adjusting bolt 33 is provided. The adjusting bolt 33 is a long bolt with a handle, which passes through the stopper 31 and the through groove 11 in turn and is connected to the connecting end of the L-shaped clamping block 32.

[0023] Among them, the block 31 is an inverted convex structure, which is inserted into the through groove 11. When in use, the L-shaped block 32 is displaced upward by rotating the adjusting bolt 33, which drives the driven wheel 4 to displace upward as a whole, so that the sanding belt 51 enters a tightened state. At this time, the sanding belt 51 will provide a pulling force, which will be converted to the entire limit mechanism 3 through the driven wheel 4 axis, so that the limit mechanism 3 will not be displaced after being fixed. When it is necessary to adjust the angle, the adjusting bolt 33 is rotated to move the L-shaped block 32 slightly downward, so that the limit structure 3 is not restricted by the tension of the sanding belt 51, so that it can slide freely in the through groove 11. After selecting a good position, tighten the adjusting bolt 33. The same applies when the sanding belt 51 needs to be replaced.

[0024] It should be noted that a row of mounting holes 13 are provided in the middle of the frame 1, and a placing plate 7 is detachably mounted in the mounting holes 13. Under the premise of not interfering with the sanding belt 51, the placing plate 7 is installed at a suitable hole position, and then a split pin is inserted into the pin hole of the placing plate 7 to fix it, which can play a role in supporting plates or placing parts to be polished.

[0025] It should be noted that the inner circle of the sanding belt 51 has anti-skid particles, so that the sanding belt 51 can effectively drive the driven wheel 4 to rotate, which is convenient for the use of the grinding drill bit 52.

[0026] It should be noted that the grinding drill bit 52 is installed in the drill bit installation hole 41 on the driven wheel 4, and can be replaced with grinding heads or polishing heads of different models, so as to facilitate people to perform grinding or polishing of fine parts.

[0027] The above are only preferred embodiments of the present invention.
