Description

Technical Field

[0001] The utility model relates to the technical field of grinding protective shell adjustment, in particular to an adjusting mechanism of a grinding device. Background Technique

[0002] A angle grinder is also a kind of grinding equipment. When in use, a semi-circular cover-shaped protective side cover will be arranged outside the grinding disc of the angle grinder to prevent sundries such as broken chips generated during grinding from splashing or hurting the staff. However, the protective side cover can only cover half of the grinding disc, and the position of the protective side cover is not convenient to adjust. Therefore, we propose an adjusting mechanism of a grinding device to solve the above problems. Content of the Utility Model

[0003] The purpose of the utility model is to solve the shortcomings existing in the prior art as put forward in the background technique, and to propose an adjusting mechanism of a grinding device.

[0004] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0005] An adjusting mechanism of a grinding device, including a protective shell connected to an angle grinder and a position adjusting mechanism for adjusting the position of the protective shell outside the grinding head of the angle grinder. The protective shell includes a protective top cover. The bottom of the protective top cover is connected to a protective side shell by bolts, and a plurality of positioning jacks are opened on the protective side shell. The position adjusting mechanism includes a connecting component and a positioning plug. The positioning plug is connected to the outer circle of the connecting component. The positioning plug includes a positioning rod. A top block is fixed at the top of the positioning rod. A spring is sleeved outside the positioning rod, and the bottom of the spring is connected to an annular connecting piece.

[0006] Preferably, the connecting component includes a clamping hoop A and a clamping hoop B. One end of the clamping hoop A and the clamping hoop B opposite to each other is movably hinged together. Locking blocks are fixed on the outer surface of the clamping hoop A and the clamping hoop B near the other end opposite to each other. During use, the clamping hoop A and the clamping hoop B are clamped at the position of the angle grinder near the grinding head, and then the two locking blocks are connected by bolts. A fixing block is connected to the outer wall of the clamping hoop B, and a through hole is opened through the top of the fixing block.

[0007] Preferably, a plurality of positioning jacks are distributed in a circumferential manner, and the plurality of positioning jacks are arranged at equal intervals. When the protective top cover is rotated and adjusted, the bottom end of the positioning rod can be inserted into the positioning jack only after the positioning jack corresponds to the through hole.

[0008] Preferably, the top of the spring is connected to the bottom of the top block, and the annular connecting piece at the bottom of the spring is connected to the top of the fixed block by bolts. The inner ring position of the annular connecting piece corresponds to and communicates with the through hole on the fixed block. The bottom end of the positioning insertion rod penetrates and is inserted into the annular connecting piece and the through hole. The spring can pull the top block downward, making the top block close to the top of the fixed block, and the bottom end of the positioning insertion rod is inserted into the corresponding positioning insertion hole.

[0009] Preferably, a lifting piece is provided at the top of the positioning plug-in. The lifting piece includes an arc-shaped lifting rod, and three connecting blocks are equidistantly fixed on the inner ring wall of the arc-shaped lifting rod. The connecting blocks correspond to the top block respectively, and the connecting blocks are connected to the top of the top block by bolts. In this way, when the arc-shaped lifting rod is lifted upward, the positioning insertion rod in the through hole can be driven to move upward through the connecting block and the top block. At this time, the spring is stretched, and the bottom end of the positioning insertion rod leaves the positioning insertion hole. Then, after the staff rotates the protective side shell to a suitable position, the positioning insertion hole corresponds to the through hole, and then the arc-shaped lifting rod is released. At this time, under the action of the spring, the bottom end of the positioning insertion rod is inserted into the positioning insertion hole again, completing the position adjustment of the protective side shell.

[0010] Preferably, a sleeve hole is penetrated through the top of the protective top cover, and a flange sleeve connected to the position of the angle grinder close to the grinding head is rotatably provided in the sleeve hole.

[0011] Preferably, the flange sleeve includes a ring part and a cylinder part. The ring part is integrally formed at the top end of the cylinder part. The outer diameter of the ring part is larger than the outer diameter of the cylinder part. The ring part is connected to the position of the angle grinder close to the grinding head by bolts. The protective top cover is rotatably sleeved outside the cylinder part. In this way, the protective top cover can be rotated to drive the protective top cover to rotate.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. In the present utility model, the protective top cover can completely cover and protect the upper part of the grinding disc, and at the same time, the protective side shell can protect half of the side part of the grinding disc. And by rotating the protective top cover, the position of the protective side shell can be conveniently adjusted. The protective top cover can be positioned by three positioning plug-ins, so that the protective side shell can prevent position deviation after adjusting the protection direction according to needs.

[0014] 2. In the present utility model, the positioning insertion rods in the positioning plug-ins can be lifted and moved upward simultaneously through the lifting piece, so that the bottom ends of the three positioning insertion rods leave the positioning insertion holes at the same time, which is convenient for releasing the positioning restriction on the protective top cover.
