Abstract
Description
Technical Field
[0001] This utility model relates to the field of tooth plate processing technology, specifically a tooth plate grinding device. Background Technology
[0002] A thread rolling die, also known as a thread rolling dies, is a special tool for machining taps and studs. It is widely used in the standard fastener industry for thread machining of screws and studs. During the manufacturing process, thread rolling dies will produce burrs, which need to be removed by a grinding device.
[0003] Because the tooth grooves formed between the teeth on the dental plate are inclined, when the dental plate is polished by the polishing roller brush, the teeth will block the polishing roller brush from polishing the tooth grooves. Therefore, the polishing roller brush is not very effective at removing burrs at the bottom of the tooth grooves and cannot meet the usage requirements. Utility Model Content

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.
[0023] like Figure 1-5 As shown, a toothed plate grinding device includes:
[0024] Mounting platform 2;
[0025] The clamping part is provided on the mounting platform 2 and is used to clamp and fix the toothed plate 1.
[0026] The deflection part is set on the mounting table 2 and is used to adjust the placement angle of the clamping jaw plate 1 on the clamping part.
[0027] The grinding section is set on the mounting table 2 and is used to grind the toothed plate 1 held on the clamping section.
[0028] Furthermore, the clamping part includes a base plate 5, which is mounted on the mounting platform 2. A fixing rod 6 is provided on the lower surface of the base plate 5. The fixing rod 6 is rotatably connected to the mounting platform 2. A limit plate 7, a limit plate 8, and a limit plate 9 are provided on the base plate 5. A stud 10 is threadedly connected to the limit plate 9. A handwheel 11 is provided at one end of the stud 10, and a circular groove 12 is rotatably connected to the other end of the stud 10.
[0029] Before grinding the toothed plate 1, it is necessary to place the toothed plate 1 first. Specifically, first place the toothed plate 1 on the base plate 5, then align the short side of the toothed plate 1 with the first limiting plate 7, and then align the long side of the toothed plate 1 with the second limiting plate 8. At this point, the position of the toothed plate 1 is completed. Then, by rotating the handwheel 11, the handwheel 11 will push the circular groove 12 towards the toothed plate 1 during the threaded connection with the third limiting plate 9. When the circular groove 12 contacts the short side of the toothed plate 1, by continuing to rotate the handwheel 11, the circular groove 12 will be brought into close contact with the toothed plate 1, thus completing the fixation of the toothed plate 1.
[0030] Furthermore, the base plate 5 and the limiting plate 8 are respectively provided with interconnected grooves 13, and also include a base frame 14, which is located inside the groove 13 and can move along the groove 13.
[0031] When the base frame 14 is completely located in the groove 13 on the base plate 5 and the second limiting plate 8, and when the toothed plate 1 is fixed on the base plate 5, the surface of the toothed plate 1 and the base frame 14 maintain a 2mm gap, that is, the toothed plate 1 does not contact the base frame 14. After the grinding of the toothed plate 1 is completed, the circular groove 12 is moved away from the toothed plate 1 by rotating the handwheel 11 in the opposite direction. At this time, the toothed plate 1 can be pulled away from the second limiting plate 8 by one end of the base frame 14. When the toothed plate 1 is not completely pressed on the base plate 5, there is space under the toothed plate 1, which makes it convenient for the staff to lift the toothed plate 1 from below and transfer the toothed plate 1 away.
[0032] Furthermore, the deflection part includes a vertical rod 15 disposed under the base plate 5, a ball screw 16 disposed on the mounting platform 2, a screw cap 17 disposed at one end of the ball screw 16, a guide rod 18 disposed on the mounting platform 2, and a slide 19 disposed on one end of the slide 19 threadedly connected to the ball screw 16, and the other end of the slide 19 slidably connected to the guide rod 18. A slot 20 is provided on the slide 19, and the guide rod 18 is located inside the slot 20. An arc-shaped groove 21 for moving the vertical rod 15 is provided on the mounting platform 2.
[0033] To facilitate grinding of the tooth plate 1 by the grinding unit, the placement angle of the tooth plate 1 needs to be adjusted. Specifically, when the tooth inclination angle on the tooth plate 1 is 3°, rotating the screw cap 17 drives the ball screw 16 to rotate. Then, through the threaded connection between the slide 19 and the ball screw 16, and the sliding connection between the slide 19 and the guide rod 18, the slide 19 moves linearly along the guide rod 18. When the slide 19 moves linearly, the vertical rod 15 can move within the arc-shaped groove 21 through the retaining groove 20 on the slide 19. The width of the slot 20 is slightly larger than the diameter of the vertical rod 15. The width of the slot 20 is 10mm, and the diameter of the vertical rod 15 is 9.6mm. When the slide 19 moves, it can simultaneously drive the vertical rod 15 to move. The gap between the slot 20 and the vertical rod 15 is within the allowable error range of the toothed plate 1 angle adjustment. The mounting platform 2 is equipped with a scale 3, and the base plate 5 is equipped with an indicator plate 4. Through the indicator plate 4 and the scale 3, the rotation angle of the toothed plate 1 can be accurately controlled. As long as the error of the rotation angle of the toothed plate 1 is not greater than 1°, it meets the requirements of the rotation angle of the toothed plate 1.
[0034] Because the distance between the indicator plate 4 and the fixed rod 6 is relatively far, even if the base plate 5 needs to rotate at a small angle, the distance that the indicator plate 4 moves will be magnified, allowing the staff to intuitively observe the angle of rotation of the base plate 5.
[0035] Meanwhile, the angle of the toothed plate 1 can be adjusted by controlling the number of rotations of the knob, which is to adjust the pitch of the ball screw 16. Marking points are set on the knob and the mounting plate 2. When the knob is aligned with the marking points on the mounting plate 2, this is the initial state of the knob and the base plate 5. When it is necessary to control the toothed plate 1 to rotate 3° clockwise, it is only necessary to control the knob to rotate 3 times clockwise. When it is necessary to control the toothed plate 1 to rotate 3° counterclockwise, it is only necessary to control the knob to rotate 3 times counterclockwise.
[0036] Furthermore, the grinding section includes two support plates 22, on which copper wire rollers 23 are mounted. A motor 24 for driving the copper wire rollers 23 to rotate is mounted on one side of the support plate 22. Through slots are opened on both sides of the upper surface of the mounting platform 2, and lead screws 25 are respectively installed inside the two through slots. A base 26 threadedly connected to the lead screws 25 is installed at the lower end of the support plate 22. A housing 27 is installed on one side of the mounting platform 2. A rotating shaft 30 is installed inside the housing 27. A motor 28 is mounted on the housing 27. The two ends of the rotating shaft 30 are connected to the lead screws 25, and the output end of the motor 28 is connected to the rotating shaft 30 through bevel gear sets 29.
[0037] By starting the motor 24, the copper wire roller 23 can be driven to rotate. When the copper wire roller 23 rotates, it can polish the teeth on the tooth plate 1. Since the placement angle of the tooth plate 1 is adjusted, the copper wire on the copper wire roller 23 can enter the tooth groove on the tooth plate 1, which can facilitate the simultaneous polishing of the teeth on the tooth plate 1 and the burrs in the tooth groove.
[0038] When all the burrs on the teeth of the tooth plate 1 need to be polished, the motor 28 is started and the bevel gear set 29 is driven to rotate the shaft 30. Then, through the transmission of the bevel gear set 29 at both ends of the shaft 30, the two lead screws 25 are driven to rotate. Then, through the threaded connection between the base 26 and the lead screw 25, the two support plates 22 are driven to move in the same direction and at the same speed along the lead screw 25, which in turn drives the copper wire roller 23 to move. When the copper wire roller 23 moves, it can polish the tooth plate 1.
[0039] The two support plates 22 can be connected by a reinforcing plate 31 to improve the stability of the two support plates 22 when moving.
[0040] When the overall thickness of the toothed plate 1 is relatively thin, a shim with a thickness of 1mm can be evenly placed on the base plate 5 first, and then the toothed plate 1 can be placed on the shim to raise the height of the toothed plate 1 so as to facilitate the grinding of the toothed plate 1.
[0041] The hardness of the copper wire roller 23 is lower than that of the toothed plate 1, which can reduce the impact on the toothed plate 1 during the deburring process.
[0042] The starting, stopping, speed, and direction parameters of motor 1 (24) and motor 2 (28) are all controlled by the motor control module, which is existing technology and will not be described in detail here.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
