Description

Technical Field

It includes a grinding workbench, and the four corner ends of the bottom surface of the grinding workbench are respectively fixedly connected to a base, and a controller is fixedly connected to the left wall of the grinding workbench. A collection box is provided at the rear of the grinding workbench, and a material feeding mechanism is provided on the top surface of the grinding workbench. The material feeding mechanism includes a guide pipe, a fixed seat, a screw, a first drive motor, a movable block and a pusher rod. The guide pipe is fixedly connected to the top surface of the grinding workbench through support plates on both sides, and the fixed seat is fixedly connected to the top surface of the grinding workbench and is located below the guide pipe. The screw is movably connected to the top surface of the fixed seat through rotating rods at both ends. By coordinating the use of the material feeding mechanism, the grinding mechanism and the clamping mechanism, compared with the manual grinder method, it not only saves time and effort and reduces labor intensity, but also greatly improves work efficiency.

[0004] The cylindrical grinding device for automotive parts disclosed in the above-mentioned existing patent saves time and effort and reduces labor intensity, but it still has obvious limitations in actual application scenarios.

Since the through hole inside the grinding drum is conical, the iron chips that fall into the grinding drum can fall to the lower left side. Then, under the guidance of the two guide ramps, the iron chips will eventually fall into the chip box and be automatically collected, thereby effectively improving the convenience of the grinding device during subsequent cleaning work.

[0026] A discharge port 401 is provided on the top right side of the guide tube 4, and a first notch 402 is provided on the left outer peripheral surface of the guide tube 4 in a front-to-back symmetrical shape. A strip-shaped opening 403 is provided on the bottom right side of the guide tube 4 to facilitate the passage of the T-shaped driving block 502.

[0028] The spring sleeved on the outside of the sliding rod 602 is located between the vertical fixed plate 601 and the clamping plate 603, and the outer end of the sliding rod 602 is fixedly connected to a circular limit block; the two vertical fixed plates 601 in the left group of clamping and orienting mechanisms 6 are respectively fixedly connected to the upper end surfaces of the two horizontal fixed plates 103, and the two vertical fixed plates 601 in the right group of clamping and orienting mechanisms 6 are both fixedly connected to the upper end surface of the grinding workbench 1.

[0030] When the clamping and orienting mechanism 6 is in the clamping state, the outer peripheral surface of the rubber roller 604 is in close contact with the outer peripheral surface of the pipe 9 passing through the guide tube 4 and the guide cylinder 7, so that the pipe 9 inside the guide tube 4 and the guide cylinder 7 can only move in the left and right directions, but cannot rotate circumferentially, ensuring that the arc-shaped grinding stone 305 can stably and efficiently grind the outer peripheral surface of the pipe 9, thereby improving the grinding effect.

[0031] A U-shaped fixing plate 701 is fixedly connected to the top of the guide barrel 7, and the U-shaped fixing plate 701 is fixedly installed on the upper ends of two vertical fixing plates 601 in a group of clamping and orienting mechanisms 6 on the left side.

[0032] Example 2, based on Example 1, Figure 1 and Figure 11 As shown, a discharge opening 801 is provided on the top rear side of the material guide shell 8, and the front side of the bottom end face of the material guide shell 8 is distributed in a downward inclined shape; a discharge port is provided on the bottom front side of the material guide shell 8, and the discharge port of the material guide shell 8 is located above the discharge port 401. At least ten pipe fittings 9 can be placed in the material guide shell 8 at a time. Since at least ten pipe fittings 9 can be placed in the material guide shell 8 at a time, batch continuous processing is realized, which effectively improves the processing efficiency of the pipe fittings 9.

[0033] The working principle of the present invention is as follows: when in use, first place the pipe fitting 9 into the guide housing 8, and then, under the action of the inclined guide housing 8, a pipe fitting 9 on the front side of the guide housing 8 rolls down into the guide tube 4, and then the control box 2 controls the telescopic rod of the electric cylinder 501 to retract, and drives the T-shaped driving block 502 and the pushing rod 503 to move linearly to the left, thereby driving the pipe fitting 9 inside the guide tube 4 to move to the left, so that the left end of the pipe fitting 9 is inserted between the four arc-shaped grinding stones 305, and at this time, the inner walls of the four arc-shaped grinding stones 305 are in close contact with the outer peripheral surface of the left end of the pipe fitting 9, and then the control box 2 is used to start the grinding motor 304, which drives the driving pulley, the driven pulley and the grinding drum 303 to rotate, and then the grinding drum 303 drives the guide block 307, the square slider 309, the clamping rod 306 and the arc-shaped grinding stone 305 to rotate, and the rotating arc-shaped grinding stone 305 grinds the outer peripheral surface of the pipe fitting 9 The grinding process is carried out, and during the grinding process, the telescopic rod of the electric cylinder 501 is controlled to continue to retract, driving the T-shaped driving block 502 and the pushing rod 503 to move straight to the left, thereby driving the pipe fitting 9 inside the guide tube 4 to continue to move to the left, and then when the pushing rod 503 moves to the left to the limit position, the telescopic rod of the electric cylinder 501 is controlled to extend, thereby driving the pushing rod 503 to move right and reset. When the pushing rod 503 moves to the right and resets, a pipe fitting 9 on the front side of the guide shell 8 loses its limiting effect and continues to roll into the guide tube 4, and then is pushed to the left by the pushing mechanism 5, and the operation is circulated to complete the grinding operation of a large number of pipe fittings 9. The ground pipe fittings 9 are finally discharged through the left end of the guide cylinder 7, and then under the action of gravity, the left end of the ground pipe fitting 9 will first hang down, and then fall into the collection box 10 for automatic collection.

[0034] When the pipe fitting 9 moves to the left, when the pipe fitting 9 passes through the guide tube 4 and the guide cylinder 7 from right to left in sequence, the outer peripheral surface of the pipe fitting 9 will be in close contact with the outer peripheral surface of the rubber roller 604, so that the pipe fitting 9 inside the guide tube 4 and the guide cylinder 7 can only move in the left and right directions, but cannot rotate circumferentially, thereby avoiding the phenomenon that the rotating arc grinding stone 305 rotates with the pipe fitting 9, so that the arc grinding stone 305 can effectively grind the outer peripheral surface of the pipe fitting 9, thereby greatly improving the grinding effect.

[0035] When the pipe 9 is ground by the arc-shaped grinding stone 305, the iron chips generated will fall into the grinding drum 303. Since the through hole inside the grinding drum 303 is conical, the iron chips that fall into the grinding drum 303 can fall to the lower left side, and then under the guidance of the two guide inclined plates 104, the iron chips will finally fall into the chip collection box 102 and be automatically collected.
