Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automatic grinding, in particular to a hydraulic transmission device for automatic grinding equipment. Background Art
[0002] Introduction to automatic grinding machine: Fully automatic grinding machine is a machine that grinds and removes burrs on the surface of workpieces through mechanical force and abrasives. Its main principle is to use a high-speed rotating grinding head to rub and wear the surface of the workpiece to achieve the purpose of grinding and finishing.
[0003] Currently, most of the automatic grinders on the market are hydraulically driven. When the grinding head rotates at high speed to rub and wear the workpiece surface, a large amount of dust is easily generated. This may make it difficult to observe the degree of grinding on the workpiece surface, easily leading to lower grinding fineness. In addition, a large amount of dust will pollute the environment and have an impact on the human body. Utility Model Content
[0004] The utility model aims to provide a hydraulic transmission device for automatic grinding equipment, which solves the existing problems.
[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0007] Furthermore, the rotating gear is an incomplete gear, and the teeth on the rotating gear are matched with the teeth on the gear rod. When the rotating gear rotates and meshes with the gear rod, it drives the gear rod to move rightward.
[0008] Furthermore, the one-way valve on the suction pipe is unidirectionally conductive toward the inside of the liquid tank, and the one-way valve on the spray pipe is unidirectionally conductive toward the outside of the liquid tank. When the piston rod moves to the right, negative pressure is formed in the liquid tank, thereby sucking water from the water tank through the suction pipe. When the piston rod subsequently moves to the left to restore, it squeezes the water in the liquid tank and sprays it out through the spray pipe.
[0009] Furthermore, a nozzle is provided at one end of the water spray pipe away from the liquid bin, and the other end of the water spray pipe away from the liquid bin is close to the grinder. The nozzle makes the water flow sprayed from the water spray pipe more stable and uniform, and the water sprayed from the water spray pipe can reduce dust near the grinder.
[0010] Furthermore, the anti-blocking stirring mechanism includes a rotating rod, a transmission belt and a filter screen. The rotating rod penetrates and is rotatably connected to the lifting plate and the water tank. A stirring paddle is fixedly connected to the top of the rotating rod. The rotating rod is connected to the rotating shaft through a transmission belt. The filter screen is fixedly connected to the end of the suction pipe away from the liquid bin.
[0011] Furthermore, the stirring paddle is located inside the water tank and is close to the filter screen. When the stirring paddle rotates, the water flow near the filter screen is accelerated to prevent clogging of the filter screen.
[0012] Furthermore, the filter screen is made of stainless steel, which has high strength and is not easily deformed, rusted or damaged.
[0013] The utility model has the following beneficial effects:
[0014] 1. The utility model is provided with a water spray dust reduction mechanism, so that the motor is turned on to drive the rotating shaft to rotate. The rotating shaft drives the grinding tool to rotate for grinding. The water in the water tank is sucked into the liquid bin by the cooperation of the rotating gear, the gear rod, the piston rod and other components, and then sprayed to the grinding tool through the water spray pipe, so as to achieve the effect of dust reduction, prevent dust from flying and polluting the environment and affecting the operator's sight.
[0015] 2. The utility model is provided with an anti-blocking stirring mechanism, so that the water in the water tank can be filtered through the filter when the water suction pipe draws water in the filter to prevent the entry of debris and blockage. At the same time, the stirring paddle is driven by the cooperation of the rotating rod and the conveyor belt to stir the water at the filter to prevent the filter from being blocked.
[0016] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0027] The rotating gear 81 is an incomplete gear, and the teeth on the rotating gear 81 match the teeth on the gear rod 85. When the rotating gear 81 rotates and meshes with the gear rod 85, the gear rod 85 is driven to move rightward.
[0028] The one-way valve on the suction pipe 86 is unidirectionally conductive toward the inside of the liquid tank 82, and the one-way valve on the spray pipe 87 is unidirectionally conductive toward the outside of the liquid tank 82. The movement of the piston rod 84 to the right will cause negative pressure to form in the liquid tank 82, thereby sucking water from the water tank 88 through the suction pipe 86. When the piston rod 84 subsequently moves to the left to restore, it will squeeze the water in the liquid tank 82 and spray it out through the spray pipe 87.
[0029] A nozzle is provided at one end of the water spray pipe 87 away from the liquid tank 82 , and the other end of the water spray pipe 87 away from the liquid tank 82 is close to the grinder 10 . The nozzle makes the water flow sprayed from the water spray pipe 87 more stable and uniform. The water sprayed from the water spray pipe 87 can reduce dust near the grinder 10 .
[0030] The anti-blocking stirring mechanism 9 includes a rotating rod 91, a transmission belt 93 and a filter screen 94. The rotating rod 91 penetrates and is rotatably connected to the lifting plate 5 and the water tank 88. A stirring paddle 92 is fixedly connected to the top of the rotating rod 91. The rotating rod 91 is transmission-connected to the rotating shaft 7 through the transmission belt 93. The filter screen 94 is fixedly connected to the end of the suction pipe 86 away from the liquid bin 82.
[0031] The stirring paddle 92 is located inside the water tank 88 , and the stirring paddle 92 is close to the filter screen 94 . When the stirring paddle 92 rotates, the water flow near the filter screen 94 is accelerated to prevent the filter screen 94 from being blocked.
[0032] The stirring paddle 92 is located inside the water tank 88 , and the stirring paddle 92 is close to the filter screen 94 . When the stirring paddle 92 rotates, the water flow near the filter screen 94 is accelerated to prevent the filter screen 94 from being blocked.
[0033] A specific application of this embodiment is: fix the workpiece to be polished on the polishing table 2 by a clamp, start the hydraulic cylinder 4 to drive the lifting plate 5 to move up and down to adjust the distance between the polishing tool 10 and the workpiece, start the motor 6 to drive the rotating shaft 7 to rotate, the rotation of the rotating shaft 7 drives the polishing tool 10 to rotate quickly to polish the surface of the workpiece, and at the same time, the rotation of the rotating shaft 7 will also drive the rotating gear 81 to rotate. At the beginning, when the rotating gear 81 rotates and meshes with the gear rod 85, it will drive the gear rod 85 to move right. The gear rod 85 moves right and drives the piston rod 84 to move right. The reset spring 83 is stretched, and the piston rod 84 moves right, which will form a negative pressure in the liquid bin 82, thereby sucking water in the water tank 88 through the suction pipe 86. When the rotating gear 81 rotates to the point where there is no negative pressure, the water in the water tank 88 is sucked through the suction pipe 86. When the tooth part is out of engagement with the gear rod 85, the return spring 83 rebounds and drives the piston rod 84 and the gear rod 85 to move to the left and restore. At this time, when the piston rod 84 moves to the left and restores, it will squeeze the water in the liquid tank 82 so that it will be sprayed out through the water spray pipe 87, thereby forming a circulation. Water is sprayed to the grinder 10 through the water spray pipe 87, which has the effect of reducing dust, preventing dust from flying and polluting the environment and affecting the operator's line of sight. The filter screen 94 can filter the water in the water tank 88 when the suction pipe 86 absorbs it. At the same time, the rotation of the shaft 7 will also drive the rotating rod 91 to rotate through the transmission belt 93. The rotation of the rotating rod 91 drives the stirring paddle 92 to rotate. The rotation of the stirring paddle 92 stirs the water at the filter screen 94 to prevent the filter screen 94 from being blocked.
