Description

Technical Field

[0001] The utility model belongs to the technical field of diamond grinding wheels, and particularly relates to a protective cover shell capable of adjusting the grinding position of a diamond grinding wheel. Background Art

[0002] During the workpiece processing, a diamond grinding wheel is used to grind the side burrs of the workpiece. The diamond grinding wheel is shielded by a protective cover shell to avoid damage to the human body by the diamond grinding wheel. However, it is impossible to accurately adjust the alignment of the workpiece. During grinding, the workpiece is placed flat on the operation platform, and the worker pushes the workpiece to move relative to the diamond grinding wheel. However, when producing different workpieces, the distance between the burr position of the workpiece and the bottom surface of the workpiece is different. When the workpiece is placed on the operation platform, the position of the burr of the workpiece and the diamond grinding wheel is different. When the burr position corresponds to the oblique tangent position of the diamond grinding wheel, when the oblique tangent position of the diamond grinding wheel grinds the workpiece burr, the rest of the diamond grinding wheel will contact the rest of the workpiece, resulting in wear of the workpiece.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0016] Please refer to Figures 1 - 4 , the present utility model provides the following technical solutions: A protective housing capable of adjusting the grinding position of a diamond grinding wheel, including a diamond grinding wheel protective housing 1 and a connecting sleeve 11. A material loading positioning plate 2 is provided on one side of the diamond grinding wheel protective housing 1. The bottom end of the material loading positioning plate 2 is fixedly connected with a support rod 21. The bottom end of the support rod 21 is rotatably connected with an adjusting screw rod 22. The outer wall of the adjusting screw rod 22 is threadedly connected with an adjusting support plate 23. The adjusting support plate 23 is fixedly connected with the diamond grinding wheel protective housing 1. The bottom end of the material loading positioning plate 2 is fixedly connected with a transparent plastic plate 3. A reference scale 31 is provided on the outer wall of the transparent plastic plate 3.

[0017] In this implementation: The staff adjusts the position of the material loading and positioning plate 2 according to the distance between the burr position of the workpiece and the bottom surface of the workpiece. During the adjustment process, the staff uses a tool to rotate the adjustment screw 22. The adjustment screw 22 rotates threadedly with the adjustment support plate 23 to adjust the position of the support rod 21, so as to adjust the position of the material loading and positioning plate 2 until the top edge of the adjustment support plate 23 is horizontally aligned with the corresponding reference scale 31 on the transparent plastic plate 3. Subsequently, the staff places the workpiece flat on the top of the material loading and positioning plate 2 and uses the material loading and positioning plate 2 to support the workpiece, so that during the operation of the staff, the position of the workpiece to be polished can correspond to the vertical tangent position of the diamond grinding wheel, so that the diamond grinding wheel can polish the workpiece with a straight tangent, avoiding the diamond grinding wheel from wearing the surrounding position of the workpiece burr and improving the polishing effect of the diamond grinding wheel on the workpiece burr. The transparent plastic plate 3 is made of transparent plastic material, so that when the staff adjusts the position of the material loading and positioning plate 2, the staff can observe the adjustment support plate 23 through the transparent plastic plate 3. The support rod 21 is rotationally connected to the adjustment screw 22, which can prevent the material loading and positioning plate 2 from rotating with the adjustment screw 22. The support rod 21 is composed of a central main support rod and side strengthening support rods to support the material loading and positioning plate 2 at multiple points and improve the stability of the material loading and positioning plate 2 to prevent the material loading and positioning plate 2 from shifting and causing the position of the workpiece placed on the top of the material loading and positioning plate 2 to deviate from the position of the diamond.

[0018] A limit insertion rod 24 is fixedly connected to the bottom end of the material loading and positioning plate 2. The limit insertion rod 24 passes through the adjustment support plate 23. By setting the limit insertion rod 24, the material loading and positioning plate 2 can be limited by means of the adjustment support plate 23. A hole corresponding to the position of the limit insertion rod 24 is opened on the adjustment support plate 23. The limit insertion rod 24 is normally inserted into the hole in the adjustment support plate 23 to limit the rotation of the material loading and positioning plate 2, so that when the adjustment screw 22 rotates, the material loading and positioning plate 2 can move up and down.

[0019] An outer protective sleeve 32 is sleeved outside the transparent plastic plate 3. A magnetic adsorption fixing sleeve 33 is fixedly connected to the top end of the outer protective sleeve 32. The magnetic adsorption fixing sleeve 33 is magnetically connected to the material loading and positioning plate 2. When the position of the material loading and positioning plate 2 does not need to be adjusted, the staff sleeved the outer protective sleeve 32 and the magnetic adsorption fixing sleeve 33 outside the transparent plastic plate 3 and magnetically fixed the magnetic adsorption fixing sleeve 33 at the bottom end of the material loading and positioning plate 2. By setting the outer protective sleeve 32, the transparent plastic plate 3 and the reference scale 31 can be protected to prevent impurities during the operation from adhering to the transparent plastic plate 3 and affecting the light transmittance of the transparent plastic plate 3. The magnetic adsorption fixing sleeve 33 can position the outer protective sleeve 32.

[0020] A notch adjustment cover 4 is sleeved outside the diamond grinding wheel protection cover shell 1, and the notch adjustment cover 4 corresponds to the notch position of the diamond grinding wheel protection cover shell 1; by setting the notch adjustment cover 4, the diamond grinding wheel at the notch position of the diamond grinding wheel protection cover shell 1 can be shielded, avoiding excessive exposure of the diamond grinding wheel, so as to prevent the hand of the worker from directly contacting the diamond grinding wheel after making a mistake.

[0021] A connecting ring sleeve 41 is fixedly connected to one side of the notch adjustment cover 4. The connecting ring sleeve 41 is sleeved outside the connecting sleeve 11, and a damping washer 42 is installed between the connecting ring sleeve 41 and the connecting sleeve 11; by setting the connecting ring sleeve 41 and the damping washer 42, the worker can adjust the position of the notch adjustment cover 4 and adjust the shielding range of the notch adjustment cover 4 for the notch of the diamond grinding wheel protection cover shell 1 according to actual needs. The damping washer 42 can play a positioning role to prevent the notch adjustment cover 4 from rotating freely and affecting the grinding work of the worker.

[0022] The working principle and usage process of the present utility model: The worker measures the distance between the burr position of the workpiece and the bottom surface of the workpiece, and then adjusts the position of the loading and positioning plate 2 according to the measured position. During the adjustment process, the worker uses a tool to rotate the adjustment screw 22. The adjustment screw 22 rotates threadedly with the adjustment support plate 23 to adjust the position of the support rod 21 and thus adjust the position of the loading and positioning plate 2 until the top edge of the adjustment support plate 23 is horizontally aligned with the corresponding reference scale 31 on the transparent plastic plate 3. Then the worker places the workpiece flat on the top of the loading and positioning plate 2 and uses the loading and positioning plate 2 to support the workpiece. During the operation of the worker, the position to be ground of the workpiece corresponds to the vertical tangent position of the diamond grinding wheel, and the diamond grinding wheel grinds the workpiece with a straight tangent, and the diamond grinding wheel will not wear the surrounding position of the workpiece burr during the grinding process.
