The utility model provides a numerical control precision double-sided grinding machine, which comprises a feeding mechanism and two grinding mechanisms arranged oppositely, each grinding mechanism comprises a knife grinding wheel and a pushing mechanism connected with the knife grinding wheel, the circumferential surfaces of the knife grinding wheels are arranged oppositely, and the pushing mechanisms can push the knife grinding wheels to move oppositely. The feeding mechanism is arranged on one side of the end face of the knife grinding wheel and can move towards the grinding mechanism, and the pushing mechanism pushes the knife grinding wheel to oppositely move in the included angle direction with the horizontal direction as the reference. According to the cutter grinding device, when the cutter grinding wheel makes contact with a cutter, the cutter grinding wheel can make contact with the tip of a cutting edge more quickly, and therefore the situation that when the whole cutter is ground, grinding deformation occurs due to the fact that the cutter grinding wheel cannot make contact with the cutting edge of the cutter is avoided.

Description

Technical Field

[0001] The utility model relates to the field of automation equipment, in particular to a numerically controlled precision double-sided grinding machine. Background Art

[0002] Existing tool grinding equipment usually uses two opposing grinding wheels, and uses the circumferential surface of the grinding wheel to grind the blade of the tool when it rotates. However, the circumferential surface of the grinding wheel will be worn when grinding the blade, that is, the circumferential surface of the grinding wheel will gradually become thinner during the grinding process, thereby shortening the radius of the grinding wheel. This will make it impossible for the circumferential surface of the grinding wheel to contact the blade, resulting in grinding failure. In this case, it is necessary to push the grinding wheels to continue to move toward each other, so that the circumferential surface of the grinding wheel keeps in contact with the blade, so that the blade of the tool can continue to be ground.

[0003] However, in the above process, since the direction of pushing the grinding wheel is horizontal, the circumferential surface of the grinding wheel usually contacts the blade of the tool first. In order to solve the above problem, although the up and down lifting method is adopted to move the tool from bottom to top for grinding, due to the size of the grinding wheel itself, some blades still cannot be ground.

In the description of the present utility model, it should be noted that the use of words such as "first" and "second" to define components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above words have no special meaning, and therefore cannot be understood as limiting the scope of protection of the present utility model. In the description of the embodiments of the present application, the meaning of "multiple" is two or more, unless otherwise clearly and specifically defined.

[0029] Unless otherwise defined, all technical and scientific terms used in this specification have the same meanings as those commonly understood by technicians in the technical field of the utility model. The terms used in this specification are only for the purpose of describing specific embodiments and are not used to limit the utility model.

[0030] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0031] The preferred embodiments of the present invention are now further described in conjunction with the accompanying drawings. Figure 1 and Figure 2 As shown, a CNC precision double-sided grinder includes a feeding mechanism 100 and two relatively arranged grinding mechanisms 200, the grinding mechanism 200 includes a grinding wheel 210 and a pushing mechanism 220, the circumferential surfaces of the grinding wheels 210 are relatively arranged, the grinding wheels 210 are connected to the pushing mechanism 220, the pushing mechanism 220 can push the grinding wheels 210 to move toward each other, the feeding mechanism 100 is arranged on one side of the end surface of the grinding wheel 210 and can move toward the grinding mechanism 200, the tool to be ground is installed on the feeding mechanism 100, and the blade part of the tool faces the grinding wheel 210, and there is a suitable gap between the two grinding wheels 210.

[0032] When the feeding mechanism 100 moves toward the grinding mechanism 200, the blade portion of the tool can be inserted between the grinding wheels 210, and then the grinding wheel 210 is started to rotate to complete the grinding of the blade portion. Since the circumferential surface of the grinding wheel 210 will be worn when grinding the blade, that is, the circumferential surface of the grinding wheel 210 will gradually become thinner during the grinding process, thereby shortening the radius of the grinding wheel 210, which will make the circumferential surface of the grinding wheel 210 unable to contact the blade portion, resulting in grinding failure. In this case, it is necessary to start the pushing mechanism 220 to push the grinding wheel 210 to continue to move toward each other, so that the circumferential surface of the grinding wheel 210 keeps in contact with the blade portion, so that the blade can continue to be polished.

[0033] On the basis of the above, the pushing mechanism 220 pushes the grinding wheel 210 to move toward each other at an angle with respect to the horizontal direction, and the angle is less than 5 degrees, so that the entire blade portion can be kept from deforming while the grinding wheel 210 continues to grind the blade. The positive angle direction with respect to the horizontal direction as the reference here is to Figure 2 For example, the existing pushing mechanism 220 pushes the grinding wheel 210 to move in the horizontal direction A, while the pushing mechanism 220 of this embodiment pushes the grinding wheel 210 to move in the direction B, and there is an angle Z between the direction B and the direction A, and the angle Z is less than 5 degrees. The principle is that, compared with the existing pushing mechanism 220 which pushes the grinding wheel 210 to move in the horizontal direction, the pushing mechanism 220 pushes the grinding wheel 210 to move toward each other in the angle direction based on the horizontal direction, so that when the grinding wheel 210 contacts the tool, the grinding wheel 210 can contact the tip of the blade faster, thereby avoiding deformation caused by grinding due to the inability to contact the blade part of the tool when the entire tool is ground. Based on the above embodiment.

[0034] Preferably, the pushing mechanism 220 pushes the grinding wheel 210 to present an angle of 3 degrees with the horizontal direction as the reference. According to experiments, at 3 degrees, the grinding wheel 210 can be prevented from colliding when moving towards each other, thereby causing further wear of the grinding wheel 210. It can also ensure that when the grinding wheel 210 contacts the tool, it can preferentially contact the tip of the tool, thereby keeping the entire blade from being deformed.

[0035] On the basis of the above embodiments, Figure 3As shown, the feeding mechanism 100 includes a feeding base plate 110, on which a first sliding base 120 and two first guide rods 130 are installed. The first sliding base 120 can move along the first guide rods 130 toward the grinding mechanism 200. A lifting device 140 is installed on the top of the first sliding base 120, and a tool holder 150 is installed on the top of the lifting device 140. The lifting device 140 can drive the tool holder 150 to move up and down, and the tool to be ground is installed on the tool holder 150.

[0036] Further on the basis of the above embodiment, Figure 3 As shown, the lifting device 140 includes a lifting motor 141, which is installed on one side of the first sliding base 120 and located between the two first guide rods 130. A lifting platform 142 is installed on the driving end of the lifting motor 141, and the tool holder 150 is installed on the lifting platform 142.

[0037] On the basis of the above embodiments, Figure 3 As shown, a rotating table 160 is provided between the lifting platform 142 and the tool holder 150, and the rotating table 160 can drive the tool holder 150 to rotate. When installing the tool on the tool holder 150, the rotating table 160 can be operated first to rotate the tool holder 150 to a direction convenient for installing the tool, and then the tool is installed on the tool holder 150, and then the rotating table 160 is operated to reset, which can make the installation between the tool and the tool holder 150 more convenient.

[0038] On the basis of the above embodiments, Figure 4 and Figure 5 As shown, the pushing mechanism 220 also includes a guide rail 221 and a pushing motor 222. The guide rail 221 is set at an angle with respect to the horizontal direction. The pushing motor 222 is set on the guide rail 221 and is parallel to the guide rail 221. A second sliding base 230 is set on the driving end of the pushing motor 222. The second sliding base 230 is installed on the guide rail 221. When the pushing motor 222 is started, the pushing motor 222 can drive the second sliding base 230 to move along the guide rail 221. Preferably, a plurality of second guide rods 231 are set in the second sliding base 230. When the second sliding base 230 moves along the guide rail 221, the second guide rods 231 can guide the movement of the second sliding base 230.

[0039] On the basis of the above embodiments, Figure 4 and Figure 5As shown, a rotating device 240 is installed above the second sliding base 230, and the rotating device 240 can move synchronously with the second sliding base 230. The grinding wheel 210 is installed on the rotating device 240, and the rotating device 240 can drive the grinding wheel 210 to rotate.

[0040] On the basis of the above embodiments, Figure 4 and Figure 5 As shown, the rotating device 240 includes a rotating motor 241 and a driving shaft 242 . The grinding wheel 210 is installed on the driving shaft 242 . The rotating motor 241 drives the driving shaft 242 to rotate through a belt.

[0041] On the basis of the above embodiments, Figures 1 to 5 As shown, this embodiment also includes a control module device 300, and the control module device 300 is electrically connected to the two grinding mechanisms 200 respectively, so that corresponding parameters can be input into the control module device 300 according to the wear degree of the materials of different grinding mechanisms 200, so as to control the driving structure of the grinding mechanism 200 to drive the grinding wheel 210 to move at different speeds.

[0042] On the basis of the above embodiments, Figures 1 to 5 As shown, an exhaust pipe 410 is arranged above the grinding mechanism 200, and an exhaust fan 420 is installed at the tail end of the exhaust pipe 410. When the grinding wheel 210 grinds the tool, dust will be generated. Starting the exhaust fan 420 can use the exhaust pipe 410 to extract the dust from the top, so that the dust can affect the grinding tool.
