[0016] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present utility model belongs. The terms used herein in the specification of the present utility model are only for the purpose of describing specific embodiments and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0017] As shown Figures 1 to 4 in the figure, a precision tool holder for glass processing includes a base plate 1, a base 2, a dovetail seat 3, a locking screw 4, an angle adjuster 5, a tool holder 6 and a micrometer head 7. The base 2 is arched and is detachably mounted on the base plate 1. The dovetail seat 3 is movably mounted between the base 2 and the base plate 1. The locking screw 4 penetrates through the base 2 and is in movable contact with the top of the dovetail seat 3. The micrometer head 7 is mounted on the back of the base 2. The output end of the micrometer head 7 penetrates through the base 2 and abuts against the rear end of the dovetail seat 3. The front end of the dovetail seat 3 protrudes outside the base 2 and is used to connect with the angle adjuster 5. The tool holder 6 is mounted on the output end of the angle adjuster 5. Specifically, during use, the tool holder 6 is used to clamp the tool bit, and different types and models of tool bits can be replaced according to the type of glass to be processed. The base 2 is hollow and is used to install the dovetail seat 3 inside. The micrometer head 7 is mounted on the outside of the rear end of the base 2 and is used to finely adjust the position of the dovetail seat 3 in the X direction, thereby playing a role in finely adjusting the height of the tool holder 6. It can be understood that during processing, the entire tool holder is mounted on the output end of the machine tool and is located above the workpiece. The micrometer head 7 drives the tool holder 6 that holds the tool bit to approach or move away from the surface of the workpiece. When the tool holder moves to the specified position, the locking screw 4 is used to clamp the dovetail seat 3. The angle adjuster 5 is used to adjust the angle of the tool holder 6, so that the inclination angle of the tool bit acting on the surface of the workpiece changes during processing, which is convenient for processing glass plates with different thicknesses and models as required.

[0018] As shown Figures 1 to 4 in the figure, the dovetail seat 3 includes a stop portion 31 and a wedge-shaped seat 32. The stop portion 31 is cube-shaped and is mounted on the wedge-shaped seat 32. The bottom opening of the base 2 is trumpet-shaped and is used to match the wedge-shaped seat 32. The locking screw 4 is in movable contact with the top of the stop portion 31. The rear end of the stop portion 31 is provided with a positioning hole 311, and the output end of the micrometer head 7 is inserted into the positioning hole 311. Specifically, by using the wedge-shaped seat 32 to cooperate with the trumpet-shaped opening of the base 2, the entire dovetail seat 3 can only displace along the X direction, positioning and preventing displacement skew. In the Z direction, the stop portion 31 is fixed by the cooperation of the locking screw 4 to prevent the dovetail seat 3 from moving in the Z direction due to vibration during processing. The structure is compact and stable, and the cooperation is more precise.

[0019] As shown Figures 1 to 4As shown, the dovetail base 3 further includes a disc-shaped cover 33 and a spring 34. The disc-shaped cover 33 is installed at the rear end of the stop portion 31. The spring 34 is arranged along the X direction and is clamped between the disc-shaped cover 33 and the front inner wall of the base 2. Specifically, when the micrometer head 7 drives the dovetail base 3 to displace along the X direction so that the tool head approaches the workpiece, at this time, under the influence of the disc-shaped cover 33, the spring 34 is compressed. After the dovetail base 3 moves to the specified position, the locking screw 4 is used to press against the dovetail base 3 to prevent it from displacing, and then the grinding operation can be carried out. When the height of the tool head needs to be adjusted during processing, the locking screw 4 is loosened, and the spring 34 resets, causing the dovetail base 3 to displace in the reverse direction along the X direction, and then the height position of the tool holder 6 can be adjusted again through the micrometer head 7.

[0020] As Figure 4 shown, a packing plug 312 is further arranged in the positioning hole 311. The packing plug 321 is between the stop portion 31 and the output end of the micrometer head 7, and has a buffering effect to avoid the vibration force generated during processing being rigidly transmitted to the output end of the micrometer head 7, which is likely to cause damage to the output end of the precision micrometer head 7.

[0021] As Figure 4 shown, the angle adjuster 5 is connected to the front end of the stop portion 31 through a connecting seat 51. A notch groove 313 is provided at the front end of the stop portion 31. A fitting block 511 is provided at the rear end of the connecting seat 51 and is inserted into the notch groove 313. The fitting block 511 is assembled with the notch groove 313 to prevent assembly misalignment and ensure that the initial positions of the angle adjuster 5 are consistent, which is convenient for adjusting the angle of the tool holder 6 that holds the tool head according to the initial position subsequently.

[0022] The above embodiments only represent several implementation manners of the present invention, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
