Technical Field
[0001] The utility model relates to the technical field of surface grinders, in particular to a surface grinder with an early warning reminder function. Background Art
[0002] A surface grinder is a type of grinder that is mainly used to grind workpieces through the rotation of a grinding wheel to achieve the required flatness. It is a type of machine tool that grinds the plane or profiled surface of a workpiece. It is suitable for processing workpieces with high surface quality and high shape and dimensional accuracy. The wear of the grinding tool of a surface grinder needs to be measured regularly, and if the wear is too large, it needs to be replaced in time.
[0003] Existing surface grinders need to give early warning of the degree of wear of the mold during grinding to ensure that the mold can be replaced in time. The existing early warning method is to classify the degree of wear by the different colors of the mold, and the mold needs to be replaced in time when it is about to reach the color change point. However, this method of early warning cannot detect whether the color change point has been reached in time, resulting in the failure of timely warning, causing excessive wear of the mold and substandard parts at the production site.
[0004] Therefore, a surface grinder with early warning function is proposed. Utility Model Content
[0005] The purpose of the utility model is to provide a surface grinder with an early warning reminder function to solve the problem that the early warning method of naked eye observation proposed in the above background technology cannot timely detect whether the color change point has been reached, resulting in excessive wear of the mold and substandard parts at the production site due to the inability to provide early warning.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a fixed frame, a screw rod is rotatably connected inside the fixed frame, an optical detector is rotatably connected outside the screw rod, an engaging groove is provided on the outside of the screw rod near the top, an engaging block is engaged inside the engaging groove, a rotating sleeve is fixedly connected to the side of the engaging block away from the engaging groove, a push spring is fixedly connected to the outside of the screw rod near the engaging groove, a positioning block is fixedly connected to the end of the push spring away from the screw rod, a locking assembly is provided at the bottom of the screw rod, and the locking assembly is used to control the rotation of the screw rod.
[0007] Preferably, the engaging assembly includes a ratchet, which is fixedly connected to the bottom of the screw rod, a fixed block is engaged with the outside of the ratchet, a telescopic sleeve is fixedly connected to the outside of the fixed block, a pushing assembly is provided at the bottom of the telescopic sleeve, and the pushing assembly is used to control the lifting and lowering of the telescopic sleeve.
[0008] Preferably, the pushing assembly includes a telescopic spring, which is fixedly connected to the bottom of the telescopic sleeve. The inner side of the telescopic sleeve is smooth near the top. A sliding rod is provided inside the telescopic spring. The sliding rod is prismatic, fixedly connected to the bottom of the telescopic sleeve, and slidably connected to the bottom of the fixed frame.
[0009] Preferably, the bottom of the fixed frame is fixedly connected to a moving platform, the bottom of the sliding rod is fixedly connected to a limiting plate, the limiting plate abuts against the bottom of the screw rod, and the limiting plate is slidably connected inside the moving platform.
[0010] Preferably, the positioning block is arranged with a rounded corner at one end away from the push spring, and a shaft sleeve is rotatably connected to the outer side of the screw rod, and the shaft sleeve is fixedly connected to the top of the fixed frame.
[0011] Preferably, an alignment block is fixedly connected to one side of the optical detector, a size block is fixedly connected to one side of the fixed frame near the alignment block, a limit rod is slidably connected inside the optical detector, and the limit rod is fixedly connected inside the fixed frame.
[0012] Preferably, a grinding table is fixedly connected to the top of the movable table, a grinding wheel is arranged above the grinding table, and a fixed frame is arranged on one side of the grinding table and the grinding wheel.

[0014] Beneficial effects of the utility model:
[0015] 1. The utility model pulls the rotating sleeve to allow the engaging block to be embedded in the engaging groove and rotate, thereby driving the screw to rotate, allowing the optical detector to move along the outside of the screw and the limit rod, and adjusting the appropriate height by aligning the alignment block with the size mark block. When the optical detector detects excessive wear, it will transmit a warning signal, thereby replacing the grinding wheel in time, solving the problem of previous naked eye observation and inability to provide warning and replacement in time, and improving the accuracy of the warning.
[0016] 2. The utility model ensures that the screw rod will not reverse by engaging the ratchet inside the fixed block. When the screw rod needs to rotate in the opposite direction, it is only necessary to press the telescopic sleeve to disengage the ratchet from the fixed block. At this time, the screw rod can be rotated in the opposite direction to reset the optical detector. This solves the problem of vibration during grinding caused by using only a single rotating structure, which causes the optical detector to loosen on the surface of the screw rod, and improves the stability of the optical detector during detection.

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0027] like Figures 1 to 6 As shown, a specific embodiment of the utility model provides a surface grinder with an early warning reminder function, including a fixed frame 1, a screw rod 2 is rotatably connected inside the fixed frame 1, an optical detector 3 is rotatably connected outside the screw rod 2, an engaging groove 4 is opened on the outside of the screw rod 2 near the top, an engaging block 5 is engaged inside the engaging groove 4, a rotating sleeve 6 is fixedly connected to the engaging block 5 on the side away from the engaging groove 4, a pushing spring 16 is fixedly connected to the position of the outside of the screw rod 2 near the engaging groove 4, a positioning block 17 is fixedly connected to the end of the pushing spring 16 away from the screw rod 2, a clamping assembly is arranged at the bottom of the screw rod 2, the clamping assembly is used to control the rotation of the screw rod 2, the clamping assembly includes a ratchet 8 (the ratchet 8 is a tough material that can be deformed), the ratchet 8 is fixedly connected to the bottom of the screw rod 2, a fixed block 9 is engaged outside the ratchet 8, a telescopic sleeve 10 is fixedly connected to the outside of the fixed block 9, a pushing assembly is arranged at the bottom of the telescopic sleeve 10, and the pushing assembly is used to control the lifting and lowering of the telescopic sleeve 10.
[0028] By adopting the above technical scheme, the utility model first pulls up the rotating sleeve 6 to allow the engaging block 5 to engage into the engaging groove 4. At this time, the rotating sleeve 6 is rotated to drive the screw rod 2 to rotate, and the screw rod 2 drives the ratchet 8 to rotate along the surface of the fixed block 9, thereby controlling the optical detector 3 to adjust. When the optical detector 3 is adjusted to the specified position, the rotating sleeve 6 is pressed to allow the engaging block 5 to squeeze the positioning block 17. At this time, the pushing spring 16 will shorten. When the engaging block 5 arrives below the positioning block 17, the pushing spring 16 pushes the positioning block 17 to protrude, ensuring that the rotating sleeve 6 is positioned, thereby ensuring that the rotating sleeve 6 rotates outside the screw rod 2, ensuring that the rotating sleeve 6 will no longer drive the screw rod 2 to rotate, and vibration will be generated during grinding. The structure of the ratchet 8 engaged with the surface of the fixed block 9 also ensures that the screw rod 2 will not rotate during vibration, thereby ensuring the stability of the detection and warning of the optical detector 3.
[0029] Specifically, Figure 4 and Figure 6 The pushing component includes a telescopic spring 14, which is fixedly connected to the bottom of the telescopic sleeve 10. The inner side of the telescopic sleeve 10 is smooth near the top. A sliding rod 13 is arranged inside the telescopic spring 14. The sliding rod 13 is arranged in a prismatic shape. The sliding rod 13 is fixedly connected to the bottom of the telescopic sleeve 10. The sliding rod 13 is slidably connected to the bottom of the fixed frame 1. The bottom of the fixed frame 1 is fixedly connected to a moving platform 20. The bottom of the sliding rod 13 is fixedly connected to a limiting plate 15, which abuts against the bottom of the screw rod 2. The limiting plate 15 is slidably connected to the inside of the moving platform 20. The positioning block 17 is rounded away from one end of the pushing spring 16. The outer side of the screw rod 2 is rotatably connected to a shaft sleeve 18, and the shaft sleeve 18 is fixedly connected to the top of the fixed frame 1.
[0030] By adopting the above technical solution, the structure of the shaft sleeve 18 wrapping the outside of the screw rod 2 can ensure that the rotation of the screw rod 2 is more stable, and the shaft sleeve 18 can also cooperate with the rotating sleeve 6 to ensure that the particles under grinding will not splash into the inside of the interlocking groove 4 for accumulation. When the optical detector 3 needs to move upward, it is only necessary to press the telescopic sleeve 10, compress the telescopic spring 14, and let the ratchet 8 disengage from the surface of the fixed block 9, so that the screw rod 2 can rotate in the opposite direction. When the telescopic sleeve 10 is pressed, the sliding rod 13 and the limit plate 15 slide inside the fixed frame 1 and the movable platform 20. The limit plate 15 can limit the protruding height of the sliding rod 13, and the prismatic structure of the sliding rod 13 ensures that when the ratchet 8 rotates forward, the telescopic sleeve 10 will not rotate with the ratchet 8.
[0031] Specifically, Figure 1 and Figure 4 As shown, an alignment block 11 is fixedly connected to one side of the optical detector 3, a size block 12 is fixedly connected to one side of the fixed frame 1 near the alignment block 11, a limit rod 7 is slidably connected inside the optical detector 3, the limit rod 7 is fixedly connected inside the fixed frame 1, a grinding table 19 is fixedly connected to the top of the movable platform 20, a grinding wheel 23 is arranged above the grinding table 19, a fixed frame 1 is arranged on one side of the grinding table 19 and the grinding wheel 23, protective covers 21 are fixedly connected to both sides of the movable platform 20, a grinder control panel 22 is slidably connected to the bottom of the protective cover 21, and the grinding wheel 23 is fixedly connected to one side of the grinder control panel 22.
[0032] By adopting the above technical solution, the alignment block 11 and the size block 12 can determine the position of the optical detector 3 to ensure the accuracy of the optical detector 3 during detection. When the optical detector 3 is adjusted, the limit rod 7 can be used to limit the optical detector 3 to avoid the problem of large surface wear of the optical detector 3 caused by the sliding of the optical detector 3 inside the fixed frame 1. The protective cover 21 can protect the movable platform 20 from causing damage to the circuit that controls the movement of 20 during movement, so that the movable platform 20 can move on the surface of the grinder control console 22, so that the grinding wheel 23 can grind the components, thereby improving the stability of the equipment during use.
