Abstract

PURPOSE:To relieve human bodies from fatigue and Raynaud's disease by absorbing vibration and shock upon grinding by a vibration cushioning member consisting of the combination of the soft cushioning member and the hard cushioning member. CONSTITUTION:The shaft 6 of the grindstone 1 is arranged with the vibration cushioning member A, consisting of the combination of the soft cushioning members 10, 10' and the hard cushioning member 11 at the side surface and the inner surface of the flange of grindstone side while these members are plied and pinched by the flange of the side of the shaft. According to this method, vibration and shock upon grinding may be absorbed effectively.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an auxiliary grindstone used in free grinding operations.

Grinders used for free grinding work are designated as vibrating tools and preventive measures are required, but due to the nature of the work, it is difficult to prevent vibrations appropriately, and the number of patients with white wax cancer could potentially increase. Currently, there are some cases in which legal issues have arisen regarding compensation. Therefore, in the past, it has been proposed to insert a soft cushioning material directly between the grinding wheel and the grinding wheel shaft for the purpose of preventing He. Because of the significant run-out, aliphatics have the opposite effect, and when the balance of the whetstone is unbalanced or when the whetstone is worn and its diameter becomes small, the whetstone may be damaged due to impact, and its installation is different for each model. Because the structure is specific, there is no compatibility, and there are many unused parts of the whetstone, making it uneconomical.

In view of these points, this invention prevents fatigue and white wax that adversely affect the human body by reliably absorbing and eliminating vibrations and shocks during grinding, and also prevents damage to the grindstone due to centrifugal force, stress, and other impacts. The aim is to make the system more reliable and effective than the incomplete countermeasures currently being implemented in the market, as well as to improve economical efficiency as well as compatibility that can be applied to different types of grinding machines. This provides a new whetstone for visiting the islands.

In other words, the gist of the structure is that the whetstone is attached to the whetstone shaft by arranging auxiliary cushioning members, which are a combination of soft and hard cushioning materials, on the side and inner surfaces of the whetstone-side flange, and sandwiching them together by the shaft-side flange. This invention relates to the invention of the Oshima whetstone, which is characterized by:

The following is an explanation of the embodiments based on the drawings.

Figures 1, 2, and 2 show an embodiment applied to an offset-type grindstone for use on the side, in which the tapered tightening part (2) of the grindstone (1) is connected to the fixed flange (3) on the grindstone side. It is clamped by a grinding wheel side flange consisting of a side movable tightening 7 lange (4), and the mounting protruding inside the grinding wheel side fixed 7 lange (3) is a convex part (5) f: connected to the grinding wheel shaft (6). The shaft side fixing flange (7) and the shaft side tightening flange (8) are formed on the shaft side flange, and the mounting is inserted into the fourth part (9). ), forming a cushioning member insertion gap W (a) above and below and inside the gap,
Provide a slight play gap fb between both l1iI constant flanges (3, (7)), and insert rubber or other soft cushioning material α0.00' above and below the cushioning member insertion gap M (a), and The grinding wheel (11) is tightened by interposing a hard cushioning material (11) such as a hard resin, and tightening with a screw.
) The auxiliary layer buffer member (5), which is a combination of soft buffer materials QO, QCI' and hard buffer materials (lυ), is attached to the side surfaces (upper and lower in the example diagram) and inner surface of the 7 rungs on the grindstone side for the entire grindstone shaft (6 points). The vibration and shock during grinding are effectively absorbed by mounting these by overlapping and pinching them with the flanges on the shaft side. α3) has 7 movable tightening langes (4
) is a rotating tool insertion hole. In the configuration,
To install the whetstone (1), attach it to the whetstone-side fixing flange (3) and the shaft-side flanges (7) and (8) via the seismic shock absorbing member (5) with cotton-tipped screws. The movable clamping is performed by clamping the tapered clamping portion (2) of the flange (4) between the grinding wheel side fixed flange (3).

Fig. 3 and Fig. 11 show an embodiment applied to a flat type whetstone using the outer circumferential surface. Fit and fix the side 7 flange (+4.)' and insert the two-piece shaft side flange (15) into the grindstone shaft (6) by inserting the grindstone side flange (]4) into the recess (9). For installation, insert the buffer material insertion gap (a) on the left and right and inside between the fourth part (9) and the grinding wheel side 7 lange 04).
1. Rubber or other soft cushioning materials o0.01' are interposed on the left and right sides of the cushioning member insertion gap (a), and a hard cushioning material such as hard resin (Ill f: interposed and tightened with a nut ( 16'', the soft cushioning materials QQ, QQ' and the hard cushioning materials (11 ) is arranged, and these are overlapped and sandwiched together by the shaft side flange to effectively absorb the movement and impact during grinding. The one in the picture has a convex part (5) attached to the tightening part (2) of the whetstone (1).
Split whetstone side flange (17)
18) is installed by inserting the convex part (5) into the fourth part (9) and the convex part (5) to attach the whetstone side 7 lange (17). Part charging gap (a)
K is formed, and both flanges (17), (
There is some play between Is1 [1! CD) K Motase,
Rubber or other soft cushioning material αq1←Ql is interposed on the left and right sides of the buffer member insertion gap Mf&), and a hard cushioning material such as hard resin υl) is completely interposed inside, and tightened with nuts α9). By tightening the grinding wheel (1), the entire grinding wheel shaft (6
), soft cushioning material α0. (10' and hard cushioning material (11
) is arranged, and these are overlapped and sandwiched by the shaft side flange to effectively absorb vibrations and shocks during grinding. In the embodiment shown in FIGS. 3 and 3, the two whetstone side 7 langes that are divided into two parts can be tightened together by a screw mechanism to form seven parts, but the implementation is free.

As explained above, in this invention, vibrations and impacts during grinding are reliably absorbed by the anti-static shock absorbing member made of a combination of soft shock absorbing material and hard shock absorbing material, thereby preventing fatigue and white wax that adversely affect the human body. In addition to preventing damage to the grinding wheel due to concentric force, stress, and other impacts, the anti-static shock absorbing material is combined with a hard shock absorbing material to prevent wear and center runout caused by metal-to-metal friction, increasing durability. The aliphatic effect is further enhanced. Also, is the whetstone side flange and shaft side flange relative to the whetstone shaft? Since it is installed through the machine, it is compatible and can be applied to all grinding machines from many machine manufacturers, and the structure is simple. Furthermore, since the whetstone can be used up to 7 lunges on the side of the whetstone, the economical efficiency is significantly improved along with the effect of preventing damage to the whetstone.
