Technical Field

[0001] The invention relates to the technical field of top hammer processing, in particular to a processing device for a spherical top hammer. Background Art

[0002] Chinese patent application number 202322656957.9 discloses an external cylindrical grinding device for a dome hammer, including a grinding machine table, on which a first linear guide extending in a linear direction is provided, a sliding plate is slidably fitted on the first linear guide, a table plate is rotatably connected to the sliding plate, a positioning and rotation mechanism is provided on the table plate for supporting both ends of a dome hammer blank and rotating the dome hammer, a fixed seat is provided on the side of the first linear guide, a second linear guide is rotatably connected to the fixed seat, the rotation axes of the first linear guide and the second linear guide are both vertical axes, and a grinding wheel mechanism is slidably provided on the second linear guide.

[0003] In the above technical scheme, the outer conical surface and the forming conical surface of the dome hammer blank are ground by a grinding wheel mechanism, and by adjusting the angle of the grinding wheel mechanism, the grinding wheel mechanism can be rotated to a corresponding grinding angle for grinding according to the angle requirements of the forming conical surfaces of different dome hammer blanks. However, in the above technical scheme, only the conical surface of the top hammer can be ground, and the spherical surface of the top hammer cannot be processed. Due to the material of the top hammer itself, it cannot be processed by a machining center for curved surface processing, and can only be processed by a grinding wheel. Therefore, a device that can process the spherical surface of the top hammer (for processing a curved surface diamond) is needed. Summary of the invention

[0004] The object of the present invention is to provide a top hammer processing device capable of processing the spherical surface of the top hammer (for processing a diamond with a curved surface).

[0005] To achieve the above-mentioned purpose, the present invention discloses a processing device for a spherical top hammer, comprising a frame, a first platform which can reciprocate along the horizontal X-axis direction of the frame is provided on the frame, a second platform which can reciprocate along the horizontal Y-axis direction of the frame is provided on the first platform, a positioning and rotation mechanism is provided on the second platform, the positioning and rotation mechanism is used to clamp the top hammer workpiece to fix the top hammer workpiece and drive the top hammer workpiece to rotate, a grinding mechanism is provided above the positioning and rotation mechanism, and the grinding mechanism is used to process a spherical surface at the center position of the top hammer workpiece.

[0006] When it is necessary to grind the spherical surface at the center of the top hammer, the top hammer is placed in the positioning and rotating mechanism, and the first platform drives the positioning and rotating mechanism on the second platform to move and feed along the horizontal X-axis direction of the frame, and the second platform frame drives the positioning and rotating mechanism to move and feed along the horizontal Y-axis direction until the positioning and rotating mechanism is located directly below the grinding mechanism, so that the axis of the top hammer coincides with the lower dead point of the power output end of the grinding mechanism; when it is necessary to grind the spherical surface of the convex spherical top hammer, the grinding mechanism is controlled to descend, and it is made to swing along the upper surface of the convex spherical top hammer while grinding, so as to grind out the convex spherical top hammer; when it is necessary to grind the spherical surface of the concave spherical top hammer, the grinding mechanism is controlled to descend, and it is made to maintain a vertical state while grinding (the axis of the top hammer coincides with the lower dead point of the power output end of the grinding mechanism) until the concave spherical top hammer is ground out.

[0007] The present invention arranges a grinding mechanism on the frame, and cooperates with a positioning and rotating mechanism capable of automatic feeding to position the center position of the top hammer, and then utilizes the positioning and rotating mechanism capable of driving the top hammer to rotate in cooperation with the grinding mechanism to grind out the spherical surface required for the top hammer. The grinding mechanism can adopt different processing schemes according to the different types of top hammers (including convex spherical top hammers and concave spherical top hammers), so as to improve the adaptability of the device. The present invention has the advantage of being able to perform spherical processing on different types of top hammers.

[0008] Preferably, the frame is provided with two symmetrically arranged vertical frames, the first platform is located between the two vertical frames, and the grinding mechanism is straddled on the two vertical frames.

[0009] By arranging the grinding mechanism on the stands on both sides, compared with the method of arranging the grinding mechanism on the frame through a single stand, the stability of the grinding mechanism during operation can be ensured.

[0010] Preferably, the grinding mechanism comprises lifting mechanisms respectively arranged on the two upright frames, and the power output ends of the two lifting mechanisms are commonly provided with a support beam, and the support beam is provided with a grinding wheel module.

[0014] Preferably, the grinding wheel module comprises a diamond grinding wheel and a first power motor for driving the diamond grinding wheel to rotate.

[0015] The diamond grinding wheel is driven to rotate by the first power motor to grind the spherical surface of the top hammer. Compared with the grinding method using a fixed grinding wheel, the grinding efficiency can be improved.

[0016] The diamond grinding wheel is perpendicular to the radial plane direction of the top hammer, and the diameter of the diamond grinding wheel coincides with the axis of the top hammer.

[0017] Preferably, the swing mechanism comprises a reduction belt pulley set and a second power motor for driving a driving wheel in the reduction belt pulley set, and the second power motor is fixed on the stand.

[0019] Preferably, the positioning and rotating mechanism includes an electric dividing plate fixed on the second platform, to which a tapered jacket is detachably connected, a fixed cavity with an opening toward the grinding mechanism is provided in the tapered jacket, and the tapered jacket coincides with the axis of the electric dividing plate.

[0020] The fixed cavity in the tapered jacket is used to carry the top hammer. When the top hammer performs spherical grinding, the friction between the tapered jacket and the top hammer is greater than the friction between the diamond grinding wheel and the top hammer.

[0025] Preferably, the driving wheel is a toothed pulley, the clip located on the upper side is provided with the same tooth grooves as the toothed pulley, and the belt is a toothed belt that can fit the toothed pulley and the clip.

[0026] The belt cooperates with the toothed pulley and the tooth groove of the clamping piece to drive the second platform to move along the horizontal Y-axis direction of the frame, thereby preventing slippage between the belt and the toothed pulley and between the belt and the clamping piece, resulting in deviation in feeding accuracy and seriously affecting the grinding effect of the ball surface of the top hammer.

[0027] Preferably, the upper end of the first platform is provided with two guide bars symmetrically arranged along the horizontal Y-axis direction of the first platform, and the lower end of the second platform is provided with two enclosures symmetrically arranged along the horizontal Y-axis direction of the first platform. A guide wheel is provided on one side of the two enclosures close to each other, and the guide wheel is used in conjunction with the guide bar to reduce the friction between the second platform and the first platform, and provide auxiliary support for the second platform to facilitate the relative movement of the second platform.

[0028] The present invention can process the spherical surface of the top hammer by adopting different processing schemes according to different types of top hammers (including convex spherical top hammers and concave spherical top hammers), thereby improving the adaptability of the device and having the advantage of being able to process the spherical surfaces of different types of top hammers.
