Description

Technical Field

[0001] The invention relates to the technical field of tool grinding, in particular to a tool processing and grinding mechanism capable of self-collecting waste chips. Background Art

[0002] After the CNC tool is worn, it needs to go through a fine grinding process to restore its cutting performance. It is important to keep the fixed edge angle. When grinding the tool, it is crucial to keep the fixed edge angle of the blade. You can use a magic pen to paint the blade black so that you can observe the changes in the edge angle during the grinding process. After grinding, check whether the black is completely ground off. If not, adjust the angle until it reaches the correct angle. In the process of grinding the blade, it is also important to maintain the stability of the blade and avoid shaking. During the grinding process, check the sharpness of the blade and the changes in the edge angle regularly. When using the grindstone, apply force evenly to avoid excessive wear of the blade. Therefore, it is not an easy task to grind the tool. For novices, they need to hold the tool steadily and avoid shaking to ensure the grinding effect. In many cases, the grinding position is bound to change to a certain extent when the tool is removed for observation and polished again. In this case, it is generally necessary to use a tool holder to support the tool. However, even with a tool holder, manual control is still required. The tool holder only plays a supporting role. The tool is polished by changing the inclination angle of the tool supported on the tool holder and the force with which the tool pushes the polishing disc. For novices with unstable hands, it is easy to over-grind the tool or fail to sharpen the tool.

[0003] In addition, local waste chips generated during the tool grinding process adhere to the grinding disc, affecting the roughness of the grinding disc and easily causing outward splashing. The grinding process requires careful observation, so it is easy to cause harm to the human body. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] See also Figure 1-Figure 8 The present invention provides a technical solution: when grinding a tool, in order to observe the tool more carefully, it is necessary to get close to the tool, and then relatively close to the grinding disc 4, and the generated debris will be harmful to the human body to a certain extent. In addition, when a novice is grinding, it is difficult to control the grinding angle and the grinding force, which has a certain impact on the tool. Therefore, a tool processing and grinding mechanism with self-collecting waste chips is proposed, including a frame 1 and a motor 2 installed in the frame 1. A detachable limit cover 3 is fixed on the outer side of the frame 1. The limit cover 3 A grinding disc 4 for grinding the tool is arranged inside the cover 3, and a grinding opening 31 for contacting the tool with the grinding disc 4 is arranged on the outer side of the limit cover 3. An output shaft 5 is connected to the output end of the motor 2, and the output shaft 5 passes through the grinding disc 4 and is fixed to the grinding disc 4. The output shaft 5 is driven by the motor 2 to rotate, so that the grinding disc 4 rotates. The rotating grinding disc 4 can grind the tool through the grinding opening 31. When grinding the tool, it should be noted that the edge of the tool end is grinded through the corner of the grinding disc 4 to achieve the effect of sharpening.

[0034] A chip collecting portion 6 is installed near the lower end of the limit cover 3 for processing the chips on the grinding disc 4. The chip collecting portion 6 has a cleaning layer 63 in contact with the grinding disc 4. The generated chips are cleaned by the chip collecting portion 6, so that the grinding disc 4 is kept relatively clean. During grinding, the grinding situation can be observed in real time to prevent the chips from adhering to the grinding disc 4 and affecting the grinding effect.

[0035] A grinding unit 7 for adjusting the position is installed on the outer side of the frame 1. The grinding unit 7 includes a support end 71, a support frame 72 and a support portion 73. The support end 71 and the support frame 72 are both used for adjusting the position. The support portion 73 is used to limit the tool. After the tool is limited, the grinding unit 7 can still be deformed under manual operation force to change the state of the tool and minimize the problem caused by hand shaking.

[0036] The limit cover 3 is arranged in two halves, which are used to cover the grinding disc 4, so as to avoid the harm of the grinding disc 4 to the human body as much as possible, and achieve a protective effect. When grinding, it is prevented from contacting the grinding disc 4. The lower ends of the two halves of the limit cover 3 are penetrated outward, and a driving shaft 62 is horizontally penetrated near the lower end of the limit cover 3. A transmission belt 61 is transmitted between the driving shaft 62 and the output shaft 5. The cleaning layer 63 is fixedly sleeved on the driving shaft 62, and the output shaft 5 rotates to drive the cleaning layer 63 to clean the grinding disc 4. Under the action of the transmission belt 61, the driving shaft 62 and the output shaft 5 rotate in the same direction, and the cleaning layer 63 rotates in the same direction as the grinding disc 4. Due to the upper and lower contact, the contact surface of the cleaning layer 63 and the contact surface of the grinding disc 4 move in the opposite direction, so that the grinding disc 4 is cleaned.

[0037] The cleaning layer 63 is made of sponge material and is in a T shape. It is used to cover the corners of the grinding disc 4. The sponge can avoid excessive contact force and achieve the effect of cleaning the grinding disc 4. In addition, the T shape allows the corners of the grinding disc 4 to be processed and the grinding position of the grinding disc 4 to be cleaned.

[0038] The support end 71 includes two layers of plate layers 711, which are distributed up and down and are fixed to the frame 1. An arc-shaped opening 712 is penetrated on the plate layer 711, and a vertical shaft 713 is supported between the two layers of plate layers 711. The upper and lower ends of the vertical shaft 713 extend into the upper and lower arc-shaped openings 712 respectively, and a threaded rod is fixed to the upper end of the vertical shaft 713. The threaded rod is threadedly connected to a nut for tightening the vertical shaft 713, so that the vertical shaft 713 can move along the arc-shaped opening 712, thereby changing the position of the grinding unit 7 as a whole. However, the axis of the support frame 72 coincides with the axis of the arc-shaped opening 712. Even if it rotates along the arc-shaped opening 712, the axis position of the support frame 72 can still be kept unchanged. The axis of the arc-shaped opening 712 and the axis of the support frame 72 are both the corners of the grinding disk 4. Therefore, when the tool moves, the end of the tool is still facing the corner of the grinding disk 4, thereby avoiding changes in the end position of the tool.

[0039] A connecting shaft 715 is fixed to the outer side of the vertical shaft 713, and a connecting plate 714 is sleeved on the connecting shaft 715. The connecting plate 714 is squeezed with the vertical shaft 713 through the threaded connecting nut on the connecting shaft 715. The support frame 72 is fixed to the connecting plate 714. The axis of the support frame 72 coincides with the axis of the arc-shaped opening 712. The support portion 73 is slidably clamped on the support frame 72. In order to adjust the position of the tool, the vertical shaft 713 can move along the arc-shaped opening 712, and the connecting plate 714 can be twisted. When the fastening is not particularly tight, the tool can be clamped and the state of the vertical shaft 713 and the connecting plate 714 can be adjusted at any time during the grinding process, which is convenient for changing the cutting state of the tool. It has a supporting function and also has an adjustable function.

[0040] The support frame 72 is penetrated by a slit 721 from top to bottom, and the support portion 73 includes two arc-shaped plates 731, which are respectively clamped in the upper and lower slits 721, an outer support plate 732 is fixed between the two arc-shaped plates 731, and a connecting sleeve 734 is fixed on the outer side of the outer support plate 732, and the connecting sleeve 734 is used to limit the tool, and an adjustment port 735 for adjusting the tool is opened on the outer side of the connecting sleeve 734.

[0041] The two adjusting openings 735 on the outside of the connecting sleeve 734 are symmetrical, so that the sleeve 736 can rotate at a certain angle to grind different cutting edge ends of the tool. The tool can be adjusted by 90 degrees to facilitate grinding the other cutting edge end.

[0042] A sleeve 736 is sleeved inside the connecting sleeve 734, and an extension edge 737 extends outward from the outer side of the sleeve 736. A support spring 738 is fixed to one side of the extension edge 737. A support plate 739 is sleeved outside the connecting sleeve 734, and the support plate 739 is fixed to the end of the support spring 738. The sleeve 736 is used to limit the tool. When the sleeve 736 rotates, the support spring 738 and the support plate 739 both rotate to keep the support spring 738 in a straight line to avoid twisting and ensure resistance. In addition, the resistance of the support spring 738 is used to improve the hand feel, so that when the tool is pushed, it has a feedback effect to avoid excessive wear of the tool.

[0043] The outer side of the sleeve 736 is threadedly connected with a drill chuck 74, which is used to clamp the tool. The drill chuck 74 can clamp tools of various diameters, making it easy to grind different tools.

[0044] The outer side of the support frame 72 is provided with a plurality of limit holes 722 arranged in an array, wherein a position-adjustable fastening rod 733 is inserted into the limit hole 722. The fastening rod 733 passes through an arc plate 731 to limit the arc plate 731 to prevent the arc plate 731 from moving during the grinding process.

[0045] The working principle of the present invention is as follows: under the action of the motor 2, the grinding disc 4 is rotated, and a grinding port 31 is opened on the outer side of the limit cover 3. The end of the tool is extended inward through the grinding port 31 to contact the grinding disc 4 to grind the tool. The debris generated by the grinding moves with the grinding disc 4. Through the action of the transmission belt 61, the cleaning layer 63 rotates, so that the cleaning layer 63 processes the grinding disc 4 and cleans the debris on the grinding disc 4. Under the blocking action of the limit cover 3, it can move downward to collect the debris and avoid affecting the grinding of the tool.

[0046] In addition, during the grinding process, the tool needs to be kept stable. Instability can easily cause the grinding position of the tool to shift, affecting the cutting of the tool. To this end, the tool is limited to the support portion 73, and the support portion 73 can be adjusted along the support frame 72, so that the tool is facing the grinding disc 4 at different angles. The cutting groove at the end of the tool can be facing the grinding disc 4 at different angles, and the tool can be ground at different angles, making the tool relatively stable and easy to operate. In addition, grinding the tool requires changing the tool into an inclined shape so that the tool edge can be better processed. To this end, the connecting plate 714 can be rotated along the connecting shaft 715 to tilt the support frame 72 and adjust it during the grinding process.

[0047] When the support frame 72 rotates along the connecting shaft 715, the specific position of the support frame 72 can only be changed with the specific rotation through the vertical axis 713 through the arc-shaped opening 712, so that the overall position of the support frame 72 is changed, but the axis line is kept unchanged, so that the same position of the support frame 72 can be adjusted to multiple angles, which is convenient for real-time adjustment of the tool.

[0048] The tool is clamped in the drill chuck 74 and the drill chuck 74 is threadedly connected to the sleeve 736, so that the drill chuck 74 and the sleeve 736 are fixed, and the tool extends inward from the sleeve 736, and then the sleeve 736 is pushed to compress the support spring 738, so that the end of the tool contacts the grinding disk 4 to achieve grinding. The support spring 738 has a certain resistance, which is used to improve the hand feel and avoid hand shaking. In the case of resistance, it is easier to adjust the pressure applied to the tool for easy operation. In addition, the extended edge 737 on the outer side of the sleeve 736 can rotate along the adjustment port 735 to change the angle of the tool itself and grind different cutting edges. The support spring 738 rotates as it rotates, so as to avoid the support spring 738 from twisting and being difficult to bear force.
