Description

Technical Field

[0001] This utility model relates to the field of cutting tool processing equipment technology, and in particular to a conveying device for a cutting tool edge grinding machine. Background Technology

[0002] A cutting tool face grinder is a grinding device specifically designed for grinding the cutting edge of cutting tools. The conveying device of the cutting tool face grinder is responsible for conveying the cutting tool to the grinding disc so that the grinding disc can grind the cutting edge of the cutting tool.

[0003] The existing tool edge grinding machine consists of a worktable, a grinding device mounted on the worktable, a transmission belt, a first robotic arm, and a second robotic arm. The transmission belt and the two robotic arms serve as the conveying devices for the existing tool edge grinding machine, and both robotic arms use suction cups to pick up the tool. In use, the tool is first placed at the beginning of the transmission belt, which then transports the tool to a predetermined position. The suction cup of the first robotic arm picks up the blade, and the grinding device grinds the front side of the blade. After grinding the front side, the first robotic arm transfers the tool to the suction cup of the second robotic arm, flipping it to the other side. The suction cup of the second robotic arm then picks up the back side of the blade, which is then ground by the grinding device. After grinding the back side, the second robotic arm returns the tool to the transmission belt for removal, thus completing the grinding of both sides of the tool edge.

[0004] However, if the tool is picked up and transported by the suction cup of the robotic arm, it is only suitable for single-sided grinding machines, i.e. grinding machines equipped with only one grinding disc, because the suction cup grasps the tool by adhering to one side of the blade. When the grinding machine has two grinding discs to grind both sides of the tool simultaneously, if the tool is transported by the robotic arm, the suction cup of the robotic arm will obstruct one of the blade's cutting sides, thus making it impossible to grind both sides of the tool's cutting side simultaneously. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a conveying device for a tool edge grinding machine, which can meet the conveying requirements for double-sided grinding of the tool edge.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows: a conveying device for a tool edge grinding machine, comprising a worktable, a slide seat disposed on the worktable and capable of sliding back and forth relative to the worktable, a tool fixing mechanism for fixing a tool, a first pushing mechanism disposed on the slide seat, and a second pushing mechanism for pushing the slide seat to slide back and forth. The tool fixing mechanism comprises a base disposed above the slide seat, a tool holder fixing assembly disposed on the base, and a blade support rod disposed on the base. The blade support rod is located in front of the tool holder fixing assembly, and a slot is provided on the top of the blade support rod. The first pushing mechanism can push the base to move up and down.

[0007] In the above scheme, during use, the shank of the tool is fixed to the shank fixing assembly, and the back of the blade is locked in the slot of the blade support rod. The slot prevents the blade from moving left and right, and the shank fixing assembly can fix the shank, thus securing the entire tool and ensuring the grinding effect on the blade. After the tool is fixed, the second pushing mechanism pushes the slide to move the tool back and forth, while the first pushing mechanism pushes the base to move the tool up and down. This satisfies the transmission requirements for grinding the tool. The back of the blade is supported in the slot of the blade support rod, so that there are no obstructions on both sides of the blade. This allows the two grinding discs to grind both sides of the blade simultaneously.

[0008] Furthermore, the aforementioned tool holder fixing assembly includes a fixing seat on the base and a baffle on the front side wall of the fixing seat. The baffle has a tool holder limiting mechanism on its side, which can prevent the tool holder from shifting and ensure the stability of the tool holder fixing.

[0009] Furthermore, the aforementioned tool holder limiting mechanism includes a positioning post and a positioning block located on the same side of the baffle. A positioning groove is formed under the positioning block, and the positioning post is located at the lower front of the positioning block. When it is necessary to fix the tool, the hole of the tool holder can be fitted onto the positioning post. At this time, the tool holder is located below the positioning block, and the tool blade is located above the blade support rod. Then, the tool holder is rotated upwards to insert into the positioning groove of the positioning block, while the tool blade rests against the corresponding slot on the blade support rod, thereby completing the tool fixing operation.

[0010] Furthermore, the aforementioned tool holder fixing assembly also includes two vertical plates disposed opposite each other on the base, a horizontal plate connected to the two vertical plates, and a third lead screw rotatably connected to the base at a position corresponding to the two vertical plates. The third lead screw extends outward from the upper outer side of the horizontal plate. The fixing seat is located between the two vertical plates and can slide up and down relative to the two vertical plates. The fixing seat is threadedly connected to the third lead screw. Rotating the third lead screw will drive the fixing seat to move up and down along the third lead screw. When the third lead screw is rotated, the fixing seat will move up and down along the third lead screw. At the same time as the fixing seat moves, it will drive the baffle to move. It is equivalent to adjusting the height position of the baffle by rotating the third lead screw, so that the tool holder fixing assembly can adapt to fixing tool holders of different sizes.

[0011] Furthermore, the aforementioned vertical plate has a vertical groove on its side wall, and an adjusting nut passes through the groove. The adjusting nut is threadedly connected to the side wall of the fixed seat. When the adjusting nut is tightened, it locks the fixed seat, preventing the third lead screw from being rotated to adjust the height of the fixed seat. When the adjusting nut is loosened, it releases the lock, allowing the third lead screw to be rotated to adjust the height of the fixed seat.

[0012] Furthermore, the aforementioned base is equipped with a slide bar. The blade support rod slides in conjunction with the slide bar via a support, allowing the support to slide back and forth relative to the slide bar. The blade support rod is threadedly connected to the support, and rotating the blade support rod allows it to move up and down relative to the support. This allows the back-and-forth position of the blade support rod to be adjusted by sliding the support, while rotating the blade support rod adjusts its height, enabling it to support blades of different sizes.

[0013] Furthermore, the aforementioned first pushing mechanism includes a first motor mounted on a slide, a first lead screw threadedly connected to the slide, and a first driven gear connected to the outside of the first lead screw. The upper end of the first lead screw is rotatably connected to the lower part of the base. The axis of the first driven gear is coaxial with the axis of the first lead screw. The shaft of the first motor is driven by the first driven gear. The rotation of the first driven gear simultaneously drives the first lead screw to rotate, and the rotation of the first lead screw moves up and down relative to the slide, simultaneously driving the base to move up and down. In use, turning on the first motor drives the first driven gear to rotate, which in turn drives the first lead screw to rotate. The rotation of the first lead screw moves up and down relative to the slide, and the movement of the first lead screw simultaneously drives the base to move up and down, thereby realizing the structural function of the first pushing mechanism in driving the base to move up and down.

[0014] Furthermore, the shaft of the first motor is connected to a first driving gear, which is connected to the first driven gear via a first toothed belt. In use, when the shaft of the first motor rotates, it will drive the first driving gear to rotate. The rotation of the first driving gear will be transmitted to the first driven gear via the first toothed belt, thus ensuring the transmission stability between the shaft of the first motor and the first driven gear.

[0015] Furthermore, the aforementioned first pushing mechanism also includes several guide rods slidably mounted on the slide block, and a reinforcing plate located on the worktable below the slide block. All guide rods can slide up and down relative to the slide block. The guide rods are parallel to the first lead screw, with the upper ends of the guide rods connected to the bottom of the base. The lower ends of the first lead screw pass through the bottom of the slide block and are rotatably connected to the reinforcing plate. This design improves the base's balance by adding guide rods, while the reinforcing plate enhances the structural stability of the first lead screw and guide rods, ensuring the base can rise and fall smoothly.

[0016] Furthermore, the aforementioned second pushing mechanism includes a second lead screw threadedly connected to the slide and a second motor driven by the second lead screw. The second lead screw is rotatably connected to the worktable, and a second driven gear is connected to one end of the second lead screw. The shaft of the second motor is connected to a second driving gear, which is driven by a second toothed belt. Rotating the second lead screw will cause the slide to move back and forth along the lead screw. In use, when the shaft of the second motor rotates, it will drive the second driving gear to rotate. The rotation of the second driving gear will drive the second driven gear to rotate through the second toothed belt, thereby driving the second lead screw to rotate, which in turn drives the slide to move back and forth, thus realizing the structural function of the second pushing mechanism in moving the slide back and forth.

[0017] The tool holder fixing mechanism of this utility model's tool edge grinding machine can stably fix the tool, ensuring the grinding effect of the blade. The first and second pushing mechanisms can push the tool to move up and down and back and forth, thus meeting the conveying requirements for tool grinding. The back of the blade is supported in the slot of the blade support rod, so that there are no obstructions on both sides of the blade edge. This allows both grinding discs to grind both sides of the blade simultaneously, solving the technical problem that existing robotic arms would obstruct the grinding of one edge of the blade. In addition, both the tool holder fixing assembly and the blade support rod are adjustable, so that the tool fixing mechanism can be used to fix tools of different sizes. Attached Figure Description

[0024] The accompanying drawings are for illustrative purposes only and should not be construed as limiting this patent. To better illustrate this embodiment, some components in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product. It is understandable to those skilled in the art that some well-known structures and their descriptions may be omitted in the drawings. The positional relationships described in the drawings are for illustrative purposes only and should not be construed as limiting this patent.

[0025] In the accompanying drawings of this utility model, the same or similar reference numerals correspond to the same or similar components. In the description of this utility model, it should be understood that if terms such as "upper," "lower," "left," "right," "long," and "short" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, they are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the terms used to describe positional relationships in the drawings are only for illustrative purposes and should not be construed as limiting this patent. For those skilled in the art, the specific meaning of the above terms can be understood according to the specific circumstances.

[0026] The technical solution of this utility model will be further described in detail below through specific embodiments and with reference to the accompanying drawings: Example 1 like Figure 1 , 2As shown, this embodiment provides a conveying device for a tool edge grinding machine, including a worktable 1, a slide 11 disposed on the worktable 1 and capable of sliding back and forth relative to the worktable 1, a tool fixing mechanism for fixing a tool 4, a first pushing mechanism disposed on the slide 11, and a second pushing mechanism for pushing the slide 11 to slide back and forth. The tool fixing mechanism includes a base 31 disposed above the slide 11, a tool holder fixing assembly disposed on the base 31, and a blade support rod 32 disposed on the base 1. The blade support rod 32 is located in front of the tool holder fixing assembly, and a slot 320 is provided on the blade support rod 32. The first pushing mechanism can push the base 31 to move up and down.

[0027] Specifically, the aforementioned tool holder fixing assembly includes a fixing seat 33 on the base 31 and a baffle 34 on the front side of the fixing seat 33. A tool holder limiting mechanism is provided on the right side of the baffle 34. The tool holder limiting mechanism includes a positioning post 341 and a positioning block 342 on the right side of the baffle 34. A positioning groove 3420 is provided under the positioning block 342. The positioning post 341 is located in front of and below the positioning block 342.

[0028] When using the tool fixing mechanism in this embodiment, such as Figure 3 As shown, when it is necessary to fix the tool 4, first, fit the hole of the tool shank into the positioning post 341. At this time, the tool shank of the tool 4 is located below the positioning block 342, and the blade of the tool 4 is located above the blade support rod 32. Then, rotate the tool shank of the tool 4 upward to insert it into the positioning groove 3420 of the positioning block 342. At the same time, the back of the blade of the tool 4 abuts against the corresponding slot 320 on the blade support rod 32, thus completing the fixing operation of the tool 4. The positioning groove 3420 can prevent the tool shank of the tool 4 from moving left and right or rotating upward, while the slot 320 can prevent the blade from moving left and right or rotating downward, thus securing the tool 4 firmly. When it is necessary to remove the tool 4, rotate the tool shank of the tool 4 downward to disengage it from the positioning groove 3420. At the same time, the blade of the tool 4 disengages from the slot 320. Then, pull the hole of the tool shank of the tool 4 out of the positioning post 341 to complete the removal operation of the tool 4. The operation is convenient.

[0029] The conveying device in this embodiment fixes the blade with a blade holder fixing mechanism, and the first pushing mechanism and the second pushing mechanism push the blade up and down and back and forth to meet the conveying requirements for blade grinding. The blade back is supported on the slot of the blade support rod so that there are no obstructions on both sides of the blade edge. This allows the two grinding discs to grind both sides of the blade edge at the same time, solving the technical problem that existing robotic arms would obstruct the grinding of one side of the blade edge.

[0030] like Figure 4As shown, when installing and using the conveying device of the tool edge grinding machine of this utility model, the two grinding devices 5 are first installed opposite each other on the worktable 1, and the two grinding devices 5 are respectively located on the left and right sides of the tool fixing mechanism, thereby assembling the conveying device and the two grinding devices 5 to form a tool edge grinding machine. The tool edge grinding machine can also be equipped with a control device 6, so that the control device 6 can automatically control the operation of the tool edge grinding machine, realizing automated operation of the tool edge grinding machine and saving labor costs.

[0031] In addition, the operating principle of the tool edge grinding machine is as follows: First, manually fix the tool 4 on the tool fixing mechanism, then turn on the control device 6. The control device 6 controls the second pushing mechanism to push the tool 4 forward to the position between the two grinding devices 5. Then, control the two grinding devices 5 to grind the edge 41 of the tool 4. While grinding the edge 41, the control device 6 also needs to control the second pushing mechanism and the first pushing mechanism to push the tool 4 forward and downward slowly and at a uniform speed according to the shape of the edge 41. In this way, the edge 41 of the tool 4 can be ground completely from its root to its tail. After the edge 41 is ground, control the first pushing mechanism and the second pushing mechanism to push the tool 4 to move and reset, and the grinding operation of the edge 41 of the tool 4 can be completed.

[0032] Example 2 This embodiment is a further improvement on the structure of the conveyor device of the tool face grinding machine in Embodiment 1. The improvement is as follows: Figure 2 As shown, the base 31 is equipped with a slide bar 311. The blade support rod 32 is slidably engaged with the slide bar 311 via a support 321. The support 32 can slide back and forth relative to the slide bar 311, and the blade support rod 32 is threadedly connected to the support 321. Rotating the blade support rod 32 allows it to move up and down relative to the support 321. Thus, the back-and-forth position of the blade support rod 32 can be adjusted by sliding the support 321, and the height of the blade support rod 32 can be adjusted by rotating it, allowing the blade support rod 32 to adapt to support blades of different sizes.

[0033] In addition, the aforementioned tool holder fixing assembly also includes two vertical plates 35 disposed opposite to each other on the base 31, a horizontal plate 36 connected to the two vertical plates 35, and a third lead screw 37 rotatably connected to the base 31 at a position corresponding to the position between the two vertical plates 35. The third lead screw 37 extends outward from the upper outer position of the horizontal plate 36. The fixing seat 33 is located between the two vertical plates 35 and can slide up and down relative to the two vertical plates 35. The fixing seat 33 is threadedly connected to the third lead screw 37. Rotating the third lead screw 37 will drive the fixing seat 33 to move up and down along the third lead screw 37. The side walls of the two vertical plates 35 are respectively provided with vertical grooves 350. An adjusting nut 38 is inserted in the vertical groove 350. The adjusting nut 38 is threadedly connected to the side wall of the fixing seat 33. In use, rotating the third lead screw 37 causes the fixed base 33 to move up and down along the third lead screw 37. Simultaneously, the movement of the fixed base 33 moves the baffle 34, effectively adjusting the height of the baffle 34 by rotating the third lead screw 33. This allows the tool holder fixing assembly to accommodate tool holders of different sizes. Combined with the front-to-back position adjustment and height adjustment functions of the blade support rod 32, the tool fixing mechanism can accommodate tools of various sizes, offering convenient and flexible adjustment and a wide range of applications.

[0034] In addition, during use, when the adjusting nut 38 is tightened, the fixed seat 33 can be locked, and the third lead screw 37 cannot be rotated to adjust the height of the fixed seat 33; when the adjusting nut 37 is loosened, the lock can be released, and the third lead screw 37 can be rotated to adjust the height of the fixed seat 33.

[0035] Example 3 This embodiment is a further improvement on the structure of the conveyor device of the tool face grinding machine in Embodiment 2. The improvement is as follows: Figure 1 , 5 As shown in Figure 6, the aforementioned first pushing mechanism includes a first motor 21 located on the rear side of the slide 11, a first lead screw 22 threadedly connected to the slide 11, and a first driven gear 221 connected to the outside of the first lead screw 22. The upper end of the first lead screw 22 is rotatably connected to the lower part of the base 31. The axis of the first driven gear 221 is colinear with the axis of the first lead screw 22. The rotating shaft of the first motor 21 is driven by the first driven gear 221. The rotating shaft of the first motor 21 is connected to a first driving gear 211, which is driven by the first driven gear 221 via a first toothed belt 23. This ensures the transmission stability between the rotating shaft of the first motor 21 and the first driven gear 211. The rotation of the first driven gear 221 simultaneously drives the first lead screw 22 to rotate, and the rotation of the first lead screw 22 moves it up and down relative to the slide 11, simultaneously causing the base 31 to move up and down.

[0036] When the conveying device of the tool edge grinding machine in this embodiment is used, when the shaft of the first motor 21 drives the first driving gear 211 to rotate in the forward direction, the first driving gear 211 will drive the first driven gear 221 to rotate in the forward direction through the first toothed belt 23, so that the first lead screw 22 moves upward along the slide 11 while rotating, and the first lead screw 22 will push the base 31 to move upward while moving. When the shaft of the first motor 21 rotates in the reverse direction, it will drive the first lead screw 22 to rotate in the reverse direction and push the base 31 to move downward, thereby realizing the structural function of the first pushing mechanism to push the base 31 to move up and down.

[0037] As an improvement to this embodiment, such as Figure 6 As shown, the aforementioned first pushing mechanism also includes four guide rods 24 slidably disposed on the slide block 11. The guide rods 24 can slide up and down relative to the slide block 11, and the guide rods 24 are parallel to the first lead screw 22. The upper end of the guide rods 24 is connected to the lower part of the base 31. This solution improves the movement balance of the base 31 by adding guide rods 24, and the support for the base 31 is more stable.

[0038] The aforementioned first pushing mechanism also includes a reinforcing plate 25 located on the workbench 1 below the slide 11. The lower end of the first lead screw 22 passes through the lower part of the slide 11 and is rotatably connected to the reinforcing plate 25. The lower end of the guide rod 24 passes through the lower part of the slide 11 and is fixedly connected to the reinforcing plate 25. The reinforcing plate 25 can improve the structural stability of the first lead screw 22 and the guide rod 24.

[0039] Example 4 This embodiment is a further improvement on the structure of the conveyor device of the tool face grinding machine in Embodiment 3. The improvement is as follows: Figure 1 As shown, the second pushing mechanism includes a second lead screw 71 threadedly connected to the slide 11 and a second motor 72 drivenly connected to the second lead screw 71. The second lead screw 71 is rotatably connected to the worktable 1, and a second driven gear 711 is connected to the rear end of the second lead screw 71. The second motor 72 is located on the rear side of the worktable 1, and a second driving gear 721 is connected to the rotating shaft of the second motor 72. The second driving gear 721 is drivenly connected to the second driven gear 711 through a second toothed belt 73. Rotating the second lead screw 71 will drive the slide 11 to move back and forth along the second lead screw 71.

[0040] In addition, two slide rods 12 are arranged opposite each other on the workbench 1. The slide block 11 is provided with a groove corresponding to the position of the slide rod 12. The groove of the slide block 11 slides in cooperation with the corresponding slide rod 12, so that the slide block 11 can slide back and forth along the two slide rods 12, which can improve the sliding stability of the slide block 11.

[0041] In this embodiment, when the conveying device of the tool edge grinding machine is in use, if the shaft of the second motor 72 rotates and drives the second drive gear 721 to rotate in the forward direction, the second drive gear 721 will drive the second driven gear 711 to rotate in the forward direction through the second toothed belt 73, so that the second lead screw 71 is threadedly driven to move the slide 11 forward. When the shaft of the second motor 72 drives the second lead screw 71 to rotate in the reverse direction, the second lead screw 71 will be threadedly driven to move the slide 11 backward, thereby realizing the structural function of the second pushing mechanism to push the slide 11 to move back and forth. Simultaneously, the movement of the slide 11 will drive the base 31 to move, so that when the tool 4 is fixed on the tool fixing mechanism, the second pushing mechanism can push the tool 4 to move back and forth.

[0042] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating this utility model, and are not intended to limit the implementation of this utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
