Description

Technical Field

[0001] This utility model belongs to the field of machining equipment technology, specifically relating to a grinding device for variable angle machining. Background Technology

[0002] When processing hardware products, grinding machines are required. Grinding machines use grinding wheels as cutting tools to cut the workpiece and obtain the predetermined workpiece shape. However, the grinding wheels of existing grinding machines cannot change their angle; they can only achieve single vertical or horizontal position adjustment. For workpieces that need to be processed with complex grooves, existing grinding machines cannot meet their processing requirements and the workpiece clamping position needs to be changed. This places new demands on the clamping fixture and requires a change in the clamping position, affecting the final processing efficiency.

[0003] Therefore, how to provide a grinding device that can perform machining at a variable angle is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0004] In view of this, the present invention provides a grinding device for variable angle machining, which can adjust the working swing angle of the grinding wheel and complete the complex grooving machining of the workpiece without adjusting the workpiece clamping position or angle. It is convenient to use and improves the machining efficiency and flexibility of the workpiece.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a grinding device for variable angle machining, comprising:

[0006] Mounting bracket; A grinding wheel mechanism, wherein rotating supports are fixedly provided at the middle of both sides of the grinding wheel mechanism, the grinding wheel mechanism is mounted on the mounting bracket with the rotating supports as fulcrums and rotating at a certain angle, one end of the grinding wheel mechanism is the working end, and the other end is the tilting control end; A rocking motor is fixedly connected to the mounting bracket. The output shaft of the rocking motor meshes with the rocking control end to drive and change the working angle of the working end.

[0007] The beneficial technical effects of this utility model are as follows: The grinding wheel mechanism is the basis for grinding workpieces. The workpiece is ground through the working end of the grinding wheel mechanism. Since the grinding wheel mechanism can rotate around the rotating support, the overall tilting angle of the grinding wheel mechanism can be controlled by the tilting motor during later use, thereby changing the up and down tilting angle of the working end of the grinding wheel mechanism to complete the complex groove processing of the workpiece. There is no need to adjust the clamping position of the workpiece, the processing is efficient, and it can adapt to the grooving requirements of different workpieces.

[0008] Preferably, the grinding wheel mechanism includes a bearing, an electric spindle, a tool holder, and a grinding wheel. The rotating support has two sets and is fixedly located on the two outer side walls of the bearing. The electric spindle is connected to the bearing, and one end of the electric spindle is detachably connected to the tool holder. The tool holder is fixedly connected to the grinding wheel. The grinding wheel is the working end of the grinding wheel mechanism and is driven by the electric spindle. An arc-shaped rack is provided on the side of the bearing away from the grinding wheel. The arc-shaped rack is the wobbling control end. The output shaft of the wobbling motor is fixed with a gear, and the gear meshes with the arc-shaped rack for transmission.

[0009] The resulting technical effect is that the bearing seat is provided with a rotating support and provides a fulcrum for the rotation of the grinding wheel mechanism. The electric spindle is an electrically controlled spindle, which provides a direct power source for the high-speed rotation of the grinding wheel. The up-and-down movement of the grinding wheel mechanism is controlled by the meshing relationship between the arc rack and the output shaft gear of the electric spindle motor, and the working swing angle of the grinding wheel can be adjusted according to the processing needs.

[0010] Preferably, the end of the spindle away from the grinding wheel is fixed with a tool holder quick-release drive cylinder. The electric spindle is a hollow electric spindle, and a pull rod is slidably connected inside the electric spindle. A disc spring is connected to the pull rod and abuts against the stepped hole inside the electric spindle. The disc spring causes the pull rod to tend to move closer to the tool holder quick-release drive cylinder. A pull claw is provided at the end of the pull rod away from the tool holder quick-release drive cylinder. The pull claw is used to disassemble and connect the tool holder.

[0011] The resulting technical effect is that the axial displacement of the pull rod is changed by the quick-release drive cylinder of the tool holder, thereby realizing the displacement change of the pull claw, and thus realizing the loosening and loosening process of the tool holder, which facilitates the subsequent replacement of the tool holder and brush wheel and is suitable for different types of work.

[0012] Preferably, the mounting bracket is provided with a safety cylinder near the wobbling control end, and the bearing seat is provided with a hinge bracket near the wobbling control end. The telescopic end of the safety cylinder is hinged to the hinge bracket to prevent the bearing seat from accidentally swinging.

[0013] The resulting technical effect is that the safety cylinder is designed to prevent accidental failure when the wobbling motor adjusts the wobbling angle of the grinding wheel mechanism, ensuring the stability of the working end of the grinding wheel mechanism and providing safety protection when adjusting the wobbling angle of the grinding wheel mechanism.

[0014] Preferably, the bearing seat is provided with a support plate on the side away from the grinding wheel, and the support plate is provided with an arc groove. The arc of the arc groove is set based on the rotational support distance of the electric spindle. A positioning cylinder is fixed on the mounting bracket. The piston rod of the positioning cylinder slides in the arc groove. The end of the piston rod is provided with a limiting plate. The limiting plate abuts against the support plate and restricts the up and down swing position of the support plate and the bearing seat.

[0015] The resulting technical effect is that once the tilting angle of the grinding wheel mechanism is determined, the positioning cylinder can be used to drive the limit plate to limit the tilting angle of the shaft seat, thus playing a safety limiting role when the grinding wheel structure is working at the positioning angle.

[0016] Preferably, it also includes a workpiece probe, which is fixed to the side of the mounting bracket near the grinding wheel, and is used to measure the height position of the workpiece to be processed.

[0017] The resulting technical effect is that the workpiece probe can be used to obtain the position and height of the clamped workpiece, which can be used for height compensation of the working end of the subsequent grinding wheel mechanism.

[0018] Preferably, the workpiece probe is a high-precision contact digital sensor.

[0019] The resulting technical effect is that the workpiece probe uses a digital sensor, which has high measurement accuracy and facilitates subsequent workpiece position measurement, thereby improving the workpiece processing quality.

[0020] Preferably, it also includes a grinding fluid supply pipe, which is a flexible bamboo-joint hose, and the grinding fluid supply pipe is fixed on the mounting bracket and connected to an external grinding fluid supply source.

[0021] The resulting technical effect is that the flexible bamboo-joint hose can change the spray position as needed, thereby ensuring the supply of cutting fluid during grinding.

[0022] Preferably, it also includes a lifting mechanism, the lifting end of which is fixedly connected to the mounting bracket, and the fixed end of the lifting mechanism is provided with an anti-fall cylinder, the lifting end of which is connected to the mounting bracket and provides anti-fall insurance for the mounting bracket.

[0023] The resulting technical effect is that the lifting mechanism can adjust the overall height of the grinding wheel mechanism, which facilitates the adjustment of the grinding depth. The safety cylinder also provides a safety guarantee to prevent the mounting bracket from falling due to accidental failure of the lifting mechanism.

[0024] Preferably, it further includes a horizontal sliding mechanism, the sliding end of which is fixedly connected to the fixed end of the lifting mechanism, and the horizontal sliding mechanism causes the lifting mechanism and the grinding wheel mechanism to adjust their lateral working positions.

[0025] The resulting technical effect is that the horizontal sliding mechanism is used to adjust the horizontal working position of the grinding wheel mechanism, and also for adjusting the measurement position of the subsequent workpiece probe. Attached Figure Description
