Technical Field

[0001] This utility model relates to the field of cylindrical grinding machine technology, specifically a workpiece position adjustment structure for a cylindrical grinding machine. Background Technology

[0002] External cylindrical grinding machines are used to grind the outer surfaces of cylindrical, conical, or other rotating bodies. They are precision metalworking machine tools. However, existing external cylindrical grinding machines are not convenient for chamfering the edges of workpieces. If chamfering is required, the workpiece needs to be reinstalled and fixed, which affects the continuity and efficiency of the machining process. Utility Model Content

[0003] The purpose of this utility model is to provide a workpiece position adjustment structure for an external cylindrical grinding machine, which aims to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: the workpiece position adjustment structure of the external cylindrical grinding machine includes a base, a rotatable base platform on the base, a waist hole on the lower surface of the base platform, a mounting groove on the base, a ball screw inside the mounting groove, a slide block slidably connected inside the mounting groove, the slide block being threadedly connected to the ball screw, a rod on the slide block being located inside the waist hole, a motor on the base, and synchronous pulleys on the output end of the motor and one end of the ball screw, with the two synchronous pulleys being driven by a synchronous belt.

[0005] Preferably, a groove is provided at the center of the lower surface of the base, and a protrusion is provided on the upper surface of the base.

[0006] Preferably, the upper surface of the base is provided with limiting grooves on both sides of the base platform, and the two ends of the base platform are provided with extensions, which are located in the limiting grooves.

[0007] Preferably, the angle of the base platform deflection to the left or right on the base is no greater than 15°.

[0008] Preferably, one side of the base is provided with a cover for concealing the motor, synchronous pulley and synchronous belt.

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0018] like Figure 1-5 As shown, a workpiece position adjustment structure for an external cylindrical grinding machine includes a base 5, a rotatable base 6 on the base 5, a waist hole 7 on the lower surface of the base 6, a mounting groove on the base 5, a ball screw 8 inside the mounting groove, a slide seat 9 slidably connected inside the mounting groove, the slide seat 9 and the ball screw 8 are threadedly connected, a rod 10 is provided on the slide seat 9, the rod 10 is located inside the waist hole 7, a motor 11 is provided on the base 5, and a synchronous pulley 12 is provided at the output end of the motor 11 and at one end of the ball screw 8, and the two synchronous pulleys 12 are driven by a synchronous belt 13.

[0019] The position adjustment structure is installed inside the bed of the cylindrical grinding machine. The cylindrical grinding machine also includes a headstock module 1, a tailstock module 2, a grinding wheel module 3, and a system control module. The headstock module 1 and tailstock module 2 are both mounted on the base 6. The headstock module 1 and tailstock module 2 can be used to clamp and fix the workpiece 4. At the same time, the headstock module 1 can be used to drive the rotation of the clamped workpiece 4. The position of the headstock module 1 on the base 6 is fixed. The tailstock module 2 is connected to the base 6 through a linear guide rail. The tailstock module 2 has a locking mechanism. After the position of the tailstock module 2 is adjusted, it can be locked on the base 6. The grinding wheel module 3 is used to grind the workpiece 4. The grinding wheel module 3 is located inside the bed of the cylindrical grinding machine and on one side of the base 5. The grinding wheel module 3 can move in the X-axis direction and the Y-axis direction inside the cylindrical grinding machine. The system control module is used to control the actions of each module. Since the headstock module 1, tailstock module 2, grinding wheel module 3, and system control module in the cylindrical grinding machine are all existing technologies, they will not be described in detail here.

[0020] After the workpiece 4 is clamped and fixed by the headstock module 1 and tailstock module 2, the headstock module 1 can drive the workpiece 4 to rotate. At this time, the surface of the workpiece 4 can be polished by the movement of the grinding wheel module 3 in the X and Y axes. After polishing the surface of the workpiece 4, the grinding wheel module 3 begins to move away from the workpiece 4, and then the grinding wheel module 3 and the headstock module 1 stop moving. Then the motor 11 is started. Through the cooperation of the motor 11, the synchronous pulley 12 and the synchronous belt 13, the ball screw 8 is driven to rotate. When the ball screw 8 rotates, it can drive the slide 9 in the mounting groove to move. When the slide 9 moves, it can drive the rod 10 to move. Due to the existence of the waist hole 7, when the rod 10 moves linearly along the ball screw 8, it can drive the base 6 to rotate on the base 5. By controlling the number of rotations of the ball screw 8, the rotation angle of the base 6 on the base 5 is controlled. When the base 6 rotates to a certain angle, such as Figure 3 As shown, the motor 11 stops operating, then the headstock module 1 is started to drive the workpiece 4 to rotate, and the grinding wheel module 3 is started and moved to the edge of the workpiece 4 to perform chamfering.

[0021] Regardless of how the slide 9 moves on the ball screw 8, the base plate 6 can deflect instantly according to the movement of the slide 9 through the cooperation of the rod 10 and the waist hole 7, so as to ensure that the rotation angle of the base plate 6 meets the processing requirements.

[0022] By controlling the left and right deflection of the base 6 on the base 5, the two ends of the workpiece 4 can be chamfered.

[0023] Furthermore, a groove 14 is provided at the center of the lower surface of the base 6, and a protrusion 15 is provided on the upper surface of the base 5, so that the two ends of the base 6 maintain the same angle when deflected.

[0024] Furthermore, the upper surface of the base 5 and the two sides of the base platform 6 are respectively provided with limiting grooves 16, and the two ends of the base platform 6 are respectively provided with extensions 17, which are located in the limiting grooves 16, so as to improve the stability of the base platform 6 on the base 5.

[0025] Furthermore, the base platform 6 is deflected to the left or right by no more than 15° on the base 5 to avoid the rod 10 from contacting the end of the waist hole 7, thereby improving the safety of the equipment during use.

[0026] Furthermore, a cover 18 is provided on one side of the base 5 to cover the motor 11, the synchronous pulley 12 and the synchronous belt 13. The cover 18 can prevent the iron filings generated during grinding from accumulating in large quantities at the synchronous pulley 12 and the motor 11, so as to ensure the stability of the motor 11, the synchronous pulley 12 and the synchronous belt 13 during operation.

[0027] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
