DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4 The utility model provides a technical solution: a fixing mechanism for a drilling blade end grinding machine, comprising a base 1, a base 2, a stop rod 3, a spring 4, a limit mechanism 5, a pull rod 501, a limit clamp 502, a slot 6, a positioning plate 7, an exhaust bin 8, an upper airway 9, an exhaust duct 10, a pipe head 11, a retaining ring 12, a sealing ring 13, a vacuum pump 14 and a spiral air pipe 15, the base 2 is fixedly connected to the inner wall of the lower end of the base 1, and the stop rod 3 is movably connected to the inner wall of the base 2, and the upper end of the stop rod 3 is provided with a limit mechanism 5, and the upper surface of the base 1 is movably connected to The card slot 6 has positioning plates 7 fixed at both ends of the lower surface of the card slot 6, and an exhaust chamber 8 is provided inside the card slot 6, and an upper air duct 9 is provided inside the card slot 6 above the exhaust chamber 8, and an exhaust duct 10 is provided inside the card slot 6 on the side of the exhaust chamber 8, a pipe head 11 is movably connected to the inner wall of the exhaust duct 10, and a retaining ring 12 is fixedly installed on the outer wall of the pipe head 11, and a sealing ring 13 is bonded to the outer wall of the side of the retaining ring 12, and a vacuum pump 14 is fixedly provided on the outer wall of the base 1 below the pipe head 11, and the vacuum pump 14 is connected to the pipe head 11 through a spiral air pipe 15.

[0023] The base 2 and the stop rod 3 form a sliding structure, and the end face of the stop rod 3 is connected to the inner wall of the base 2 through the spring 4, so that when the pull rod 501 moves, the pull rod 501 drives the stop rod 3 to slide relative to the base 2, and the stop rod 3 is elastically supported by the spring 4, so that the stop rod 3 drives the pull rod 501 to allow the limit clamp 502 to be stably inserted in the positioning plate 7.

[0024] The limiting mechanism 5 includes a pull rod 501 and a limiting clamp 502, and the pull rod 501 is fixedly installed on the upper end of the stop rod 3, and the upper surface of the pull rod 501 is fixed parallel to the limiting clamp 502, so that the base 1 and the slot 6 are in a relatively stable state through the limiting mechanism 5.

[0025] The pull rod 501 is slidably connected to the base 1 and the base 2 respectively, the limit card 502 and the positioning plate 7 are slidably arranged, and the positive cross-section shape of the limit card 502 is set to an "L" shape, which is convenient for the user to pull the pull rod 501, so that the pull rod 501 drives the limit card 502, allowing the limit card 502 to separate from the positioning plate 7, thereby facilitating the user to replace the card slot 6.

[0026] The base 1 and the positioning plate 7 are slidably arranged, and the base 1 and the card slot 6 are in close contact with each other, so that when the user disassembles and assembles the card slot 6, the card slot 6 drives the positioning plate 7 to slide relative to the base 1.

[0027] The exhaust chamber 8 is connected to the upper airway 9 and the exhaust duct 10 respectively, so that when the vacuum pump 14 is evacuating air, the gas in the exhaust chamber 8, the upper airway 9 and the exhaust duct 10 is discharged from the device through the pipe head 11, the vacuum pump 14 and the spiral air pipe 15, thereby generating negative pressure in the upper airway 9, thereby allowing the drilling blade to be stably positioned in the slot 6.

[0028] The exhaust duct 10 and the pipe head 11 are threadedly connected, and the sealing ring 13 and the base 1 are fitted together, so that the user can rotate the pipe head 11 conveniently, so that the retaining ring 12 drives the sealing ring 13 to be close to the base 1, thereby improving the sealing performance of the pipe head 11.

[0029] Working principle: When using the drilling insert to process the end face grinding machine fixing mechanism, first Figure 1-4 As shown, the user fixes the base 1 on the end face grinder, and then the user puts the drilling blade into the slot 6. Next, the user starts the vacuum pump 14. At this time, the gas in the exhaust chamber 8, the upper airway 9 and the exhaust duct 10 is discharged from the device through the pipe head 11, the vacuum pump 14 and the spiral air pipe 15. Then, negative pressure is generated in the upper airway 9, so that the drilling blade is stably positioned in the slot 6, thereby completing the fixation of the drilling blade on the end face grinder. Then, when it is necessary to replace a different slot 6 according to the size of the drilling blade, the user turns off the vacuum pump 14, and then the user rotates the pipe head 11 to disengage from the exhaust duct 10. At this time, the retaining ring 12 drives the sealing ring 13 away from the base 1. Next, the user pulls the pull rod 501, and then the pull rod 501 drives the limit clamp 502 away from the positioning plate 7. As the pull rod 501 moves, the stop rod 3 moves relative to the base 2 and the compression spring 4 deforms. Then the user moves the slot 6 upward. At this time, the slot 6 drives the positioning plate 7 away from the base 1, and then the user moves the new slot 6. At this time, the new slot 6 drives the new positioning plate 7 to be inserted into the base 1. Then the user loosens the pull rod 501, and then the spring 4 resets and pushes the stop rod 3 to move, and then the stop rod 3 drives the limiting mechanism 5 to make the limiting card 502 inserted into the new positioning plate 7. Then the user inserts the pipe head 11 into the new exhaust duct 10 and tightens the pipe head 11. At this time, the pipe head 11 drives the spiral air pipe 15 to twist and deform, and at the same time, the retaining ring 12 drives the sealing ring 13 to fit tightly against the new slot 6, thereby completing the replacement of the slot 6. Next, as shown above, the new drilling blade is placed in the new slot 6 for fixing, which makes it convenient for the device to fix drilling blades of different sizes. Therefore, the device is convenient for replacing the slot 6 for positioning the drilling blade, thereby facilitating the fixing of drilling blades of different sizes on the device, thereby improving the practicality of the device.
