Description

Technical Field

[0001] This application relates to the technical field of blade grinding, and particularly to an auxiliary knife grinder. Background Art

[0002] A pin refers to the wiring that leads from the internal circuit of an integrated circuit (chip) to the peripheral circuit. The pins constitute the interface of this chip. Generally, the pins of the produced components are relatively long. After being soldered to the circuit board, a pin cutter is needed to cut off the excess pins.

[0003] After the pin cutter has been used for a period of time, the cutting edge of the circular knife blade of the cutting device will be worn to varying degrees, resulting in poor cutting quality and high power consumption. At this time, it is necessary to grind the cutting edge of the circular knife blade to make the cutting edge of the circular knife blade sharper.

[0004] In the prior art, a micro motor is fixedly arranged on a frame. A grinding wheel is fixedly connected to the output shaft of the micro motor. A knife grinding seat for placing the circular knife blade is fixedly arranged on the frame. Before grinding the circular knife blade, the circular knife blade in the pin cutter is fixed to the knife grinding seat, so that the grinding wheel abuts against the cutting edge of the circular knife blade to grind the cutting edge of the circular knife blade at the abutting position.

[0005] In the above technology, the knife grinding seat is fixedly arranged on the frame, and at the same time, the circular knife blade abuts against the grinding wheel. It is difficult to install the circular knife blade on the knife grinding seat or take out the ground blade from the knife grinding seat. Therefore, improvement is still needed.

The dovetail block is fixedly connected to the bottom of the sliding table. A threaded hole is formed through the dovetail block. At the same time, the threaded hole can be threadedly connected to the lead screw, which can make the sliding table move with the rotation of the lead screw. Using the lead screw can save the manpower for pushing the sliding table. At the same time, when the lead screw stops rotating, the sliding table can be better fixed on the slide rail. The lead screw passes through the through rod hole, and the lead screw can be rotated outside the slide rail. Rotating the lead screw can drive the sliding table to move. The sliding table slides on the slide rail, further driving the mounting assembly to move and adjusting the position of the mounting assembly. Thereby, the position of the round knife blade to be ground in the mounting assembly can be moved, so that the round knife blade can be far away from the grinding member, which is convenient for replacing the round knife blade.

The slider can move on the moving frame in the direction perpendicular to the length of the sliding rail. The movement of the slider can drive the first motor to move. Adjusting the position of the slider can adjust the position of the first motor. At the same time, the mounting member is located above the moving frame, and the first motor can drive the mounting member to move, so as to adjust the position of the mounting assembly. This enables the circular knife blade to be away from the grinding member, facilitating the replacement of the circular knife blade.

[0016] Preferably, a fixing hole is formed through the side surface of the slider, internal threads are formed on the inner side wall of the fixing hole, and a bolt in the fixing hole abuts against the sliding column.

[0017] By adopting the above technical solution, by forming a fixing hole on the side surface of the slider and forming threads on the inner side wall of the fixing hole, a bolt can be threadedly connected to the fixing hole, so that the bottom of the bolt abuts against the sliding column. When grinding the circular knife blade, the slider can be fixed, and then the first motor can be fixed, thereby fixing the position of the mounting assembly.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] The following is combined with the attached Figures 1-4Further details of this application will be described below.

[0034] This application discloses an auxiliary knife grinder. Referring to Figure 1 , the auxiliary knife grinder includes a frame 1 and a grinding member 2. The frame 1 is provided with a grinding station and an installation station. The installation station is located on the side away from the grinding station. The grinding member 2 is located at the grinding station. The grinding member 2 is used to grind the round knife blade 5. A driving component for driving the grinding member 2 to grind the round knife blade 5 is fixedly arranged on the frame 1. A mounting component for placing the round knife blade 5 to be ground is slidably arranged on the frame 1, and the mounting component can move between the grinding station and the installation station.

[0035] Specifically, when the round knife blade 5 needs to be ground, the mounting component is slid to the grinding station, and at the same time, the round knife blade 5 on the mounting component is abutted against the grinding member 2. By using the driving component to provide the power for the grinding member 2 to grind the round knife blade 5, the round knife blade 5 in the mounting component can be ground by the grinding member 2; when the round knife blade 5 needs to be replaced, the mounting component is slid away from the grinding station, so that there is enough space between the mounting component and the grinding member 2 for the staff to install or disassemble the round knife blade 5.

[0036] Referring to Figure 1 , the driving component includes a second motor 23. The grinding member 2 includes a grinding wheel. The second motor 23 is fixed on the frame 1. The second motor 23 is located at the grinding station. The output shaft of the second motor 23 faces the side of the mounting component. The output shaft of the second motor 23 is coaxially fixedly connected to the grinding wheel. The grinding wheel is used to abut against the edge of the round knife blade 5. Using the second motor 23 to provide the power for the grinding wheel to grind the edge of the round knife blade 5, the second motor 23 can make the power of grinding more continuous, and at the same time save manpower.

[0037] It is worth noting that in other embodiments, the grinding member 2 can use other structures. In this embodiment, the grinding member 2 is preferably a grinding wheel. Using a grinding wheel for grinding can improve the surface quality of the grinding process, improve the efficiency of grinding the round knife blade 5, achieve the effect of low-cost processing, and the grinding wheel has a long service life, low dressing frequency, high metal removal rate, and small grinding force and good cooling effect.

[0038] Referring to Figure 1 And Figure 2, on one side of the frame 1, a slide rail 3 is provided. A slide table 4 is arranged on the slide rail 3. The slide table 4 is slidably connected to the slide rail 3. The slide table 4 can move between a grinding station and an installation station. The length direction of the slide rail 3 is the same as the moving direction of the slide table 2. The installation component is movably arranged on the slide table 4 to realize the sliding connection between the installation component and the frame 1. Specifically, the slide rail 3 is a long strip. On the side of the slide rail 3 facing the slide table 4, a dovetail groove 6 is opened. The length direction of the dovetail groove 6 is the same as the length direction of the slide rail 3. At the bottom of the slide table 4, a dovetail block 7 is provided. The bottom of the slide table 4 is fixedly connected to the dovetail block 7. The dovetail block 7 can be slidably matched with the dovetail groove 6. The width of the opening of the dovetail groove 6 is smaller than the width of the bottom of the dovetail groove 6. Correspondingly, the width of the bottom of the dovetail block 7 is larger than the width of the top of the dovetail block 7, so that the dovetail block 7 can be stably slidably arranged in the dovetail groove 6. Thus, the slide table 4 can slide more stably on the slide rail 3, and the slide table 4 can move in the direction of approaching and departing from the grinding station.

[0039] Referring to Figure 1 With Figure 2 , a lead screw 8 is rotatably arranged on the slide rail 3 through the dovetail groove 6. The length direction of the lead screw 8 is the same as the length direction of the dovetail groove 6. A threaded hole 9 is opened on the side of the dovetail block 7. The dovetail block 7 is threadedly connected to the lead screw 8 through the threaded hole 9. At the same time, the side surface of the dovetail block 7 abuts against the groove wall of the dovetail groove 6, so that the dovetail groove 6 can play a guiding role for the dovetail block 7. Thus, the slide table 4 can move as the lead screw 8 rotates. Using the lead screw 8 can save the manpower for pushing the slide table 4. A through rod hole is opened on the side groove wall of the dovetail groove 6 far from the grinding part 2. One end of the lead screw 8 passes through the through rod hole. A rotary handle 10 is fixedly connected to the lead screw 8 passing through the through rod hole. The operator can rotate the lead screw 8 outside the slide rail 3 by rotating the rotary handle 10. Rotating the lead screw 8 can drive the slide table 4 to move. The slide table 4 slides on the slide rail 3, further driving the installation component to move and adjusting the position of the installation component. Thus, the position of the round knife blade 5 to be ground in the installation component can be moved, so that the round knife blade 5 can be far away from the grinding part 2, which is convenient for replacing the round knife blade 5.

[0040] It should be noted that the lead screw 8 has a self-locking function. In the embodiment of the present application, the self-locking function of the lead screw 8 makes the position of the slide table 4 fixed and unchanged, the position of the installation component remains unchanged, and at the same time, the position of the round knife blade 5 on the installation component is fixed and unchanged when the grinding part 2 grinds the round knife blade 5 on the installation component.

[0041] The installation component can not only move along the direction of the slide rail 3, but also move along the direction perpendicular to the slide rail 3 to be applicable to different grinding scenarios. Referring to Figure 3, a moving frame is provided at the upper end of the sliding table 4, and the mounting assembly is mounted on the moving frame. The mounting assembly faces the grinding member 2. The moving frame includes a front baffle 11, a rear baffle 12 and a bottom plate 13. The bottom plate 13 is fixed to the upper surface of the sliding table 4 by bolts. The bottom end of the front baffle 11 is fixedly connected to one end of the bottom plate 13, and the bottom end of the rear baffle 12 is fixedly connected to the other end of the bottom plate 13. The front baffle 11, the rear baffle 12 and the bottom plate 13 enclose an installation cavity. A sliding column 14 is arranged in the installation cavity of the moving frame. The sliding column 14 is above the upper surface of the bottom plate 13. The height of the sliding column 14 is less than the heights of the front baffle 11 and the rear baffle 12. The length direction of the sliding column 14 is perpendicular to the length direction of the slide rail 3. One end of the sliding column 14 is fixedly connected to the front baffle 11, and the other end of the sliding column 14 is fixedly connected to the rear baffle 12. A slider 15 is sleeved on the sliding column 14. The slider 15 is slidably connected to the sliding column 14. The mounting assembly is mounted on the upper surface of the slider 15. A fixing hole 16 is formed through the surface of the slider 15. Threads are provided on the inner side wall of the fixing hole 16. By passing a bolt through the fixing hole 16, the sliding column 14 can be abutted, so that when it is necessary to make the slider 15 stationary relative to the sliding column 14, the slider 15 can be fixed, so that the slider 15 can maintain its position unchanged, and further the position of the mounting assembly can be maintained unchanged. The circular knife blade 5 is fixed on the mounting assembly, so that the position of the circular knife blade 5 can be maintained unchanged.

[0042] In the embodiment of the present application, the sliding columns 14 are selected as two parallel sliding columns 14 to further improve the sliding stability of the slider 15.

[0043] Refer to Figure 1 And Figure 4, the installation component includes a first motor 17 and a mounting member. The mounting member includes a mounting ring 18 and a connecting ring 19. The first motor 17 is fixedly connected to the upper surface of the slider 15 by bolts. A straight rod 20 is fixedly connected to the output shaft of the first motor 17, and the straight rod 20 rotates as the output shaft of the first motor 17 rotates. The output shaft of the first motor 17 is welded to one end of the straight rod 20. The mounting ring 18 is fixedly sleeved on the straight rod 20. The mounting ring 18 is located at a position of the straight rod 20 close to the first motor 17. The connecting ring 19 is fixedly connected with a cylinder 21. The cylinder 21 is located between the mounting ring 18 and the connecting ring 19. The caliber of the cylinder 21 is larger than the bottom area of the straight rod 20. A ring of convex rings 22 is arranged on one side of the cylinder 21 facing the mounting ring 18. The convex rings 22 are located on the inner cylinder wall of the cylinder 21. The central position of the convex rings 22 is communicated with the inside of the cylinder 21. The cylinder 21 can be sleeved into the straight rod 20, and the inner side wall of the convex ring 22 abuts against the side wall of the straight rod 20 to further improve the connection stability between the connecting ring 22 and the straight rod 20. The caliber of the cylinder 21 is smaller than the caliber of the ring of the circular knife blade 5. The outer cylinder wall of the cylinder 21 abuts against the side wall of the ring of the circular knife blade 5 to limit the relative position offset of the circular knife blade 5 with respect to the straight rod 20, and can play a role in limiting the circular knife blade 5. The convex ring 22 is provided with a fastening hole. The inner side wall of the fastening hole is provided with internal threads. A connecting hole is opened at a position corresponding to the fastening hole on the mounting ring 18. The inner side wall of the connecting hole is provided with internal threads. The fastening hole and the connecting hole can be threadedly connected by a bolt. The other side of the cylinder 21 is welded to the surface of the connecting ring 19 and is communicated with the central position of the connecting ring 19. The caliber of the cylinder 21 is consistent with the area of the inner side wall of the connecting ring 19. A placement cavity for placing the circular knife blade 5 is provided between the mounting ring 18 and the connecting ring 19. The mounting ring 18 and the connecting ring 19 can abut against the circular knife blade 5, enabling the mounting member and the circular knife blade 5 to rotate as the output shaft of the first motor 17 rotates. The rotation of the circular knife blade 5 enables the grinding member 2 to grind different positions of the edge of the circular knife blade 5, further enhancing the applicability of grinding the circular knife blade 5.

[0044] It should be noted that the number of connecting holes of the mounting ring 18 is preferably two, and the number of fastening holes corresponding to the convex rings 22 of the same height of the cylinder 21 should also be two. Thus, the fixation between the mounting ring 18 and the connecting ring 19 is more stable, the circular knife blade 5 abutted by the mounting ring 18 and the connecting ring 19 is more fastened, and the circular knife blade 5 rotates more stably as the mounting ring 18 and the connecting ring 19 rotate.

[0045] Specifically, when replacing the circular knife blade 5, first turn off the first motor 17 to stop it from rotating. Then, by moving the sliding table 4 or the slider 15, move the first motor 17 away from the grinding station and synchronously drive the mounting member away from the grinding station, so that the circular knife blade 5 is separated from the grinding member 2. At this time, it is convenient for the staff to replace the circular knife blade 5. When grinding the circular knife blade 5, by moving the sliding table 4 or the slider 15, move the first motor 17 towards the grinding station, drive the mounting member to reach the grinding station, make the circular knife blade 5 abut against the grinding member 2, and then make the output shaft of the first motor 17 rotate to drive the straight rod 20 to rotate, thereby driving the circular knife blade 5 to rotate.

[0046] Referring to Figure 1 , a baffle assembly is provided on the frame 1. The baffle assembly includes a fixed plate 24 and a rotating cover. The bottom end of the fixed plate 24 is fixed on the frame 1. The fixed plate 24 is located behind the grinding wheel. The rotating cover includes a top plate, a left baffle 25, a right baffle 26 and a main baffle 27. The top end of the left baffle 25 is welded to one side of the top plate, the top end of the right baffle 26 is welded to one side of the top plate, and the top end of the main baffle 27 is welded to one side of the top plate. The top end of the fixed plate 24 is hinged to one side of the top plate. The left baffle 25, the right baffle 26, the top plate, the main baffle 27 and the fixed plate 24 form a space. The left baffle 25 and the right baffle 26 are provided with avoidance holes, and the avoidance holes can pass through the output shafts of the first motor 17 and the second motor 23. When the grinding wheel needs to grind the circular knife blade 5, due to the hinge relationship between the top plate of the baffle assembly and the fixed plate 24, the baffle assembly completely covers the grinding station, so as to better control the diffusion of iron filings and make the working environment cleaner. When the grinding wheel stops grinding the circular knife blade 5, when replacing the circular knife blade 5, or when the position of the circular knife blade 5 needs to be changed, rotate the rotating cover to the fixed plate 24 through the hinge relationship.

[0047] The implementation principle of the embodiment of the present application is as follows: Through the setting of the sliding table 4, the installation component can slide along the length direction of the slide rail 3. A moving frame is provided on the sliding table 4, which can enable the installation component to move along the direction perpendicular to the length direction of the slide rail 3, so that the installation component can move in the direction of approaching and departing from the grinding station, and the position of the installation component can be adjusted. The circular knife blade 5 is fixedly installed on the installation component, so that the position of the circular knife blade 5 can be adjusted.

[0048] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited by this.
