Description

Technical Field

[0001] The present application relates to the technical field of tool passivation, and in particular to a tool passivation processing device. Background Art

[0002] The tool plays a vital role in the process of mechanical processing. It is the most active factor in the cutting process system composed of tools, machine tools and workpieces. The quality of its cutting performance directly affects the cutting productivity, processing cost, processing accuracy and processing surface quality. Tool passivation technology is a subsequent processing technology for tool grinding. It can improve the roughness accuracy level of the blade grinding surface, eliminate the defects of sawtooth, chipping or cracks on the blade edge, and extend the service life of the tool.

[0003] The existing patent (publication number: CN208147497U) discloses a tool brush passivation device, including a brush, a brush control device and a tool control device, wherein the brush control device is used to drive the brush to rotate, and the tool control device is used to drive the tool to feed and rotate in an arc at the same time. Compared with the prior art, the present application has the following advantages: in view of the different passivation effects required for different tools, by setting at least one uniform brush and at least one non-uniform brush, alternate passivation can be performed according to actual conditions to ensure the passivation effect; a control motor is added to realize the arc rotation of the tool, so that the tool can be passivated in an arc.

[0004] The tool brush passivation device mentioned in the above patent can only grind and passivate the side of the tool close to the brush at a time when passivating the tool. After grinding one side, the tool needs to be removed from the tool fixing part, and then the tool needs to be rotated 180 degrees and then installed on the tool fixing part before the other side can be passivated, resulting in a long time spent in the passivation process and low processing efficiency. Utility Model Content

[0005] In view of the shortcomings of the prior art, the present application provides a tool passivation processing equipment with the advantages of easy disassembly, etc., which solves the problem that when a tool brush passivation device is passivating a tool, only one side of the tool close to the brush can be polished and passivated each time. After polishing one side is completed, the tool needs to be removed from the tool fixing part, and then the tool is rotated 180 degrees and then installed on the tool fixing part before the other side can be passivated, resulting in a long time spent in the passivation process and low processing efficiency.

[0006] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a tool passivation processing equipment, comprising a support frame, a fixed plate fixedly connected to the upper end of the support frame, a fixed frame fixedly connected to one side of the upper end of the fixed plate, a linear module fixedly connected to the surface of the fixed frame, a connecting frame fixedly connected to the surface of a slide that is slidably connected inside the linear module, an end of the connecting frame away from the linear module is fixedly connected to a connecting plate, and a third motor is fixedly connected to the upper end of the connecting plate.

[0007] The output end of the third motor passes through the connecting plate and is fixedly connected to a rotating plate, a plurality of mounting blocks distributed in a circular array are fixedly connected to the lower end of the rotating plate, and an electric chuck is fixedly connected to the lower ends of the plurality of mounting blocks distributed in a circular array.

[0008] Through the above scheme, a threaded rod is fixedly connected inside the rotating cylinder, a brush roller is sleeved on the outside of the threaded rod, and two groups of four brush wheels distributed in a circular array are fixedly connected to the outer wall of the rotating cylinder. When in use, the tool is fixed on the electric chuck, and then the second motor is started. The second motor cooperates with the linear module to drive the connecting frame and the connecting plate to move downward, thereby driving the rotating plate and the tool to move downward until the tool is between the brush roller and the brush wheel. Then the first motor is started to drive the rotating cylinder to rotate, and then the brush roller and the brush wheel will rotate synchronously with the rotating cylinder. At the same time, the third motor is started, and the third motor drives the rotating plate and multiple tools to rotate in the opposite direction of the rotating cylinder. During use, various surfaces of multiple tools can be polished at the same time, and the processing efficiency is relatively high.

[0009] Furthermore, a second motor is fixedly connected to the upper end of the linear module, and an output end of the second motor is fixedly connected to the upper end of a lead screw that is rotatably connected inside the linear module.

[0010] Through the above scheme, the lead screw is a key component in the linear module for realizing linear motion. It is usually connected to the slide of the module through a thread. When the lead screw rotates, the slide will move linearly along the guide rail. When the second motor rotates, the lead screw will also rotate synchronously.

[0011] Furthermore, a mounting plate is fixedly connected inside the support frame, and a first motor is fixedly connected to the lower end of the mounting plate.

[0012] Through the above solution, the mounting plate is used to mount and support the first motor to ensure that the first motor can work stably during use.

[0013] Furthermore, the output end of the first motor passes through the mounting plate and is fixedly connected to the rotating cylinder. The upper end of the mounting plate is fixedly connected to a circular slide rail. The surface of the circular slide rail is slidably connected to four sliders distributed in a circular array. The upper end of the slider is fixedly connected to the lower end of the rotating cylinder.

[0014] Through the above solution, when the rotating drum rotates, the slider moves along the circumference of the circular slide rail due to the fixed connection between the slider and the rotating drum.

[0015] Furthermore, a threaded column is fixedly connected inside the rotating cylinder, a brush roller is slidably sleeved outside the threaded column, a first nut is threadedly connected to one end of the threaded column, and a lower end of the first nut abuts against the surface of the brush roller.

[0016] According to the above solution, the first nut is screwed off, and because the brush roller is slidably connected to the threaded column, the brush roller can be removed from the threaded column to be replaced.

[0017] Furthermore, two groups of mounting frames are fixedly connected inside the rotating cylinder, wherein each group consists of four mounting frames distributed in a circular array, a threaded rod is slidably connected inside the mounting frame, one end of the threaded rod passes through the mounting frame and is fixedly connected to a brush wheel, and the end of the threaded rod away from the brush wheel is threadedly connected to a second nut.

[0018] According to the above solution, when the brush wheel needs to be replaced, the second nut is screwed off and then the threaded rod and the brush wheel can be taken out to replace the brush wheel.

[0019] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0020] The tool passivation processing equipment comprises a threaded rod fixedly connected inside a rotating cylinder, a brush roller sleeved outside the threaded rod, and two groups of four brush wheels distributed in a circular array fixedly connected to the outer wall of the rotating cylinder. When in use, the tool is fixed on an electric chuck, and then the second motor is started. The second motor cooperates with the linear module to drive the connecting frame and the connecting plate to move downward, thereby driving the rotating plate and the tool to move downward until the tool is between the brush roller and the brush wheel. Then the first motor is started to drive the rotating cylinder to rotate, and then the brush roller and the brush wheel will rotate synchronously with the rotating cylinder. At the same time, the third motor is started, and the third motor drives the rotating plate and multiple tools to rotate in the opposite direction of the rotating cylinder. During use, various surfaces of multiple tools can be polished at the same time, and the processing efficiency is relatively high. BRIEF DESCRIPTION OF THE DRAWINGS

The upper end of the linear module 16 is fixedly connected to a second motor 17, and the output end of the second motor 17 is fixedly connected to the upper end of a lead screw connected for rotation inside the linear module 16. The lead screw is a key component in the linear module 16 for realizing linear motion, and it is usually connected to the slide of the module through a thread. When the lead screw rotates, the slide will make a linear motion along the guide rail, and when the second motor 17 rotates, the lead screw will also rotate synchronously.

[0029] See also Figure 1A mounting plate 2 is fixedly connected inside the support frame 1, and a first motor 3 is fixedly connected to the lower end of the mounting plate 2. The mounting plate 2 is used to install and support the first motor 3 to ensure that the first motor 3 can work stably during use. The output end of the first motor 3 passes through the mounting plate 2 and is fixedly connected to a rotating cylinder 4. A circular slide rail 5 is fixedly connected to the upper end of the mounting plate 2. Four sliders 6 distributed in a circular array are slidably connected to the surface of the circular slide rail 5. The upper end of the slider 6 is fixedly connected to the lower end of the rotating cylinder 4. When the rotating cylinder 4 rotates, the slider 6 moves along the circumference of the circular slide rail 5 due to the fixed connection between the slider 6 and the rotating cylinder 4.

[0030] See also Figure 2 and Figure 4 , a threaded column 7 is fixedly connected inside the rotating cylinder 4, and a brush roller 8 is slidably sleeved outside the threaded column 7. A first nut 9 is threadedly connected to one end of the threaded column 7, and the lower end of the first nut 9 abuts against the surface of the brush roller 8. The first nut 9 is unscrewed. Because the brush roller 8 is slidably connected to the threaded column 7, the brush roller 8 can be removed from the threaded column 7 to replace the brush roller 8. Two groups of mounting frames 10 are fixedly connected inside the rotating cylinder 4, each group of which is composed of four mounting frames 10 distributed in a circular array. A threaded rod 11 is slidably connected inside the mounting frame 10, one end of the threaded rod 11 passes through the mounting frame 10 and is fixedly connected to a brush wheel 12, and a second nut 13 is threadedly connected to one end of the threaded rod 11 away from the brush wheel 12. When the brush wheel 12 needs to be replaced, the second nut 13 is unscrewed, and then the threaded rod 11 and the brush wheel 12 can be taken out to make the brush wheel 12 more slippery.

[0031] In this embodiment, a threaded column 7 is fixedly connected inside the rotating cylinder 4, a grinding brush roller 8 is sleeved outside the threaded column 7, and two groups of four grinding brush wheels 12 distributed in a circumferential array are fixedly connected to the outer wall of the rotating cylinder 4. When in use, the tool is fixed on the electric chuck 23, and then the second motor 17 is started. The second motor 17 cooperates with the linear module 16 to drive the connecting frame 18 and the connecting plate 19 to move downward, thereby driving the rotating plate 21 and the tool to move downward until the tool is between the grinding brush roller 8 and the grinding brush wheel 12. It can grind all surfaces of multiple tools at the same time, which greatly improves the processing efficiency. Compared with the traditional grinding method one by one, this parallel processing method significantly reduces the processing time.

[0032] The working principle of the above embodiment is:

[0033] The tool to be sharpened is fixed on the electric chuck 23. At this time, the tool should be located at the lower end of the rotating plate 21. Then the second motor 17 is started. The second motor 17 is connected to the linear module 16. When the second motor 17 is started, it will drive the screw inside the linear module 16 to rotate. Since the screw and the slide of the linear module 16 are connected by threads, the slide will move downward along the guide rail. The lower end of the slide is fixedly connected to the connecting frame 18. Therefore, the connecting frame 18, the connecting plate 19, the third motor 20, the rotating plate 21 and the tool fixed on the electric chuck 23 will move downward synchronously. This process will continue until the tool is completely between the grinding brush roller 8 and the grinding brush wheel 12. When the tool reaches the predetermined position, the first motor 3 is started. The output end of the first motor 3 is fixedly connected to the rotating cylinder 4, so the rotating cylinder 4 will start to rotate. Since the lower end of the rotating cylinder 4 is fixedly connected to the four sliders 6, and the four sliders 6 slide on the circular slide rail 5, the rotating cylinder 4 will move along a circular path. At the same time, the brush roller 8 on the threaded column 7 inside the rotating cylinder 4 and the brush wheel 12 on the outer wall of the rotating cylinder 4 will start to rotate. At this time, the third motor 20 is started, and the third motor 20 will drive the rotating plate 21 and the multiple tools thereon to rotate in the opposite direction to the rotating cylinder 4. In this way, all surfaces of the tools will be polished under the action of the brush roller 8 and the brush wheel 12.
