[0036] The present application will be further described below in conjunction with the accompanying drawings and embodiments, so that those skilled in the art can implement the present application according to the description in the specification.

[0037] It should be understood that the terms such as "have", "contain" and "include" used herein do not exclude the presence or addition of one or more other elements or combinations thereof.

[0038] As Figures 1-6As shown, the present application provides a simple and quick fixing device for wire drawing wheel, which comprises a fixing device main body 100, the fixing device main body 100 comprises a pressure ring 1 and an extension rod 2, here the wire drawing wheel 3 is installed on the extension rod 2, in order to fix the wire drawing wheel 3, the pressure ring 1 is installed on the upper end of the extension rod 2, the two are convenient and quick to fix, and in order to cooperate with the use of the pressure ring 1, the bottom of the extension rod 2 is provided with a fixed platform 21, the bottom of the fixed platform 21 is provided with an upper groove 22, further, the upper end of the wire drawing wheel rod 4 is installed in the upper groove 22, so that the wire drawing wheel 3 is fixed by the joint action between the pressure ring 1 fixed on the upper end of the extension rod 2 and the fixed platform 21 at the bottom of the extension rod 2, preventing the wire drawing wheel 3 from loosening, thereby ensuring that the wire drawing wheel is completely locked.

[0039] Further, the middle part of the above-mentioned pressure ring 1 is provided with a first fixing hole 11, further, a transverse inner fixing plate 12 is installed in the first fixing hole 11, and the transverse inner fixing plate 12 is connected with the upper end of the extension rod 2 through a first fixing bolt 13, so as to realize the fixed installation of the pressure ring 1 and the extension rod 2.

[0040] Further, the above-mentioned transverse inner fixing plate 12 divides the first fixing hole 11 into two second fixing holes 14, two outer extension rods 23 are installed on the wire drawing wheel rod 4, the two outer extension rods 23 are through holes 20, and the two outer extension rods 23 and the two second fixing holes 14 are matched with each other, so that the outer extension rod 23 extends into the second fixing hole 14, the transverse inner fixing plate 12 is located between the two outer extension rods 23, and further, a fixed via hole 121 is arranged on the transverse inner fixing plate 12, a first threaded hole 40 is arranged on the wire drawing wheel rod 4, so that the first fixing bolt 13 can pass through the fixed via hole 121, the through hole 20 and extend to be screwed in the first threaded hole 40, so as to realize the further fixed connection between the pressure ring 1 and the extension rod 2, and the extension rod 2 and the wire drawing wheel rod 4, and increase the firmness.

[0041] Further, the outer extension rod 23 is provided with a fixed counterbore 24, two second threaded holes 41 are arranged on the wire drawing wheel rod 4, the second threaded holes 41 are located on both sides of the first threaded hole 40, and a second fixing bolt 25 is installed in the fixed counterbore 24, so that the lower end of the second fixing bolt 25 can be screwed in the second threaded hole 41, through the design of the above structure, the pressure ring 1 and the extension rod 2 are further fixed to the upper end of the wire drawing wheel rod 4, and the firmness is increased.

[0042] Further, in order to prevent the wire drawing wheel 3 from rotating on the extension rod 2, a non-slip pattern 5 is formed on the bottom of the pressure ring 1, the non-slip pattern 5 extrudes the surface of the wire drawing wheel 3 and cooperates with the extension rod 2 to limit the position, so as to increase the friction, thereby ensuring that the wire drawing wheel 3 is completely locked.

[0043] Further, the anti-skid lines 5 include a plurality of radial lines 51 and a middle ring line 52, wherein the plurality of radial lines 51 are distributed radially around the axis of the compression ring 1, and the middle ring line 52 is located in the middle of the plurality of radial lines 51, so that the anti-skid lines 5 have anti-skid blocks 53, which are pressed by the contact between the plurality of anti-skid blocks 53 and the drawing wheel 3, so as to prevent the drawing wheel 3 from rotating.

[0044] Further, the lower part of the drawing wheel rod 4 is arranged in the motor cover 6, and the bottom of the motor cover 6 is provided with a locking bottom cover 61, which is used to fix the drawing wheel rod 4 in the motor cover 6. Further, a shaft coupling 62 is arranged in the locking bottom cover 61, and the shaft coupling 62 is connected to the bottom of the drawing wheel rod 4, and the shaft coupling 62 can be fixed to the motor. Through the above structure, the drawing wheel simple and rapid fixing device can be fixed to the motor for work.

[0045] Further, the motor cover 6 is further provided with a bearing assembly 63, and the locking bottom cover 61 is further provided with a locking inner groove 64, wherein the locking inner groove 64 is provided with a locking pressing ring 65, the locking pressing ring 65 abuts against the bearing assembly 63, and the lower part of the drawing wheel rod 4 passes through the locking pressing ring 65. The locking pressing ring 65 provides abutting support for the bearing assembly 63 in the locking bottom cover 61, so that the drawing wheel rod 4 can rotate well in the bearing assembly 63, and the drawing wheel rod 4 works.

[0046] Further, the shaft coupling 62 is arranged at the bottom of the drawing wheel rod 4, and the drawing wheel rod 4 is connected to the output shaft of the motor through the shaft coupling 62, so as to facilitate the motor to drive the eccentric shaft 3 to drive the grinding disc 7 to process the workpiece. Since dust is generated during the grinding and polishing process of the workpiece, the motor needs to be protected. Therefore, the protection module 8 is arranged on the output shaft of the motor, and the protection module 8 is located below the shaft coupling 62. The protection module 8 can prevent dust from entering the rotating space between the output shaft of the motor and the motor shell, and can prevent the cooling liquid or polishing liquid sprayed during grinding and polishing from entering the motor, so as to increase the protection function of the motor.

[0047] As Figures 7-18As shown, further, the protective module 8 comprises an inner cap 81, an upper cap 82, a rotatable body 83, and an inner pulling mechanism 84. It can be understood that the inner cap 81 and the upper cap 82 are made of a material with a certain elasticity, such as rubber, silicone, plastic, etc. Here, the inner cap 81 is sleeved on the output shaft, and the upper cap 82 is rotatably connected to the rotatable body 83. The inner pulling mechanism 84 is installed on the inner wall of the rotatable body 83. The inner cap 81 has a first pulling ring 821, and the first pulling ring 821 has a vertical downward pull rod 822. The vertical downward pull rod 822 is slidably arranged in a second pulling ring 811 of the inner cap 81 and is connected to the inner pulling mechanism 84. Therefore, when installing the protective module 8, first, the protective module 8 is sleeved on the output shaft, and then the rotatable body 83 is rotated, and the rotatable body 83 drives the inner pulling mechanism 84 to act on the vertical downward pull rod 822, so that the vertical downward pull rod 822 pulls the first pulling ring 821 in the upper cap 82 downward, and then the first pulling ring 821 can be attached to the second pulling ring 811. In this way, the entire protective module 8 is in a closed state, and the protective module 8 cooperates with the shaft coupling 62 to shield the output shaft, achieving dustproof and liquid-proof effects. Especially in the production task of grinding and polishing a large number of workpieces, it improves the better use effect and reduces the production cost.

[0048] Further, the inner pulling mechanism 84 comprises an inner moving rod 841, a first guide ring 842, and a second guide ring 843. Here, the first guide ring 842 is installed on the inner wall of the rotatable body 83, so that the rotatable body 83 can drive the first guide ring 842 to rotate. Since the first guide ring 842 is installed with the inner moving rod 841, the inner moving rod 841 has an enlarged end 844, and the inner cap 81 has a special-shaped guide rail groove 812, so that the enlarged end 844 is slidably arranged in the special-shaped guide rail groove 812. When the inner moving rod 841 drives the enlarged end 844 to move along the special-shaped guide rail groove 812, on the one hand, the enlarged end 844 is pressed into the special-shaped guide rail groove 812, which also presses the inner cap 81, further increasing the firmness between the inner cap 81 and the output shaft, avoiding the inner cap 81 from moving on the output shaft. On the other hand, since the special-shaped guide rail groove 812 is roughly Z-shaped, as the enlarged end 844 moves in the special-shaped guide rail groove 812, the entire first guide ring 842 is driven to move downward. The second guide ring 843 is also driven downward by the transverse spring 845, so that the vertical support rod 846 on the second guide ring 843 drives the horizontal pull rod 847 to pull the vertical downward pull rod 822 downward. In this way, the vertical downward pull rod 822 pulls the first pulling ring 821 in the upper cap 82 downward, and then the first pulling ring 821 can be attached to the second pulling ring 811. In this way, the entire protective module 8 is in a closed state.

[0049] Further, the inner cap sleeve 81 is provided with an auxiliary mechanism 85, which includes an auxiliary plate 851 and an inner movable block 852. The auxiliary mechanism 85 is used to fix the horizontal pull rod 847 to prevent the horizontal pull rod 847 from moving horizontally during use, so that the inner pull mechanism 84 is loose. The auxiliary plate 851 is installed on the outer wall of the inner cap sleeve 81, and the auxiliary plate 851 is provided with a guide hole, and two vertical guide rods are installed in the guide hole. The inner movable block 852 is installed on the vertical guide rods and can move up and down on the vertical guide rods. Further, a plurality of first protruding tooth groove rods 853 are movably installed in the guide hole, and a second protruding tooth groove is provided on the side wall of the inner movable block 852. When the horizontal pull rod 847 is moved by the vertical support rod 846, the inner movable block 852 moves in the guide hole, and the first protruding tooth groove rod 853 can engage the second protruding tooth groove to fix the inner movable block 852, preventing the horizontal pull rod 847 from moving in the opposite direction.

[0050] Further, the bottom of the auxiliary plate 851 is rotatably installed with a linkage disc 854, and two C-shaped guide rails 855 are installed in the linkage disc 854. The lower part of the first protruding tooth groove rod 853 is arranged in the C-shaped guide rail 855. Correspondingly, a linkage rod 856 is installed on the vertical support rod 846, and the linkage rod 856 and the linkage disc 854 can be selectively connected. The linkage rod 856 is designed horizontally and located on one side of the horizontal pull rod 847. Further, a spring telescopic member 857 and an inverted T-shaped insertion rod 858 are installed on one side of the auxiliary plate 851. One end of the inverted T-shaped insertion rod 858 is connected with the spring telescopic member 857. A special-shaped lifting rod 831 is provided on the rotatable body 83. The special-shaped lifting rod 831 is approximately Z-shaped, so that the special-shaped lifting rod 831 can selectively abut against the other end of the inverted T-shaped insertion rod 858.

[0051] Therefore, when the rotatable body 83 is rotated, the horizontal pull rod 847 moves along the inner movable block 852 and drives the inner movable block 852 downward. At the same time, the linkage rod 856 also drives the linkage disc 854 to rotate. The two C-shaped guide rails 855 in the linkage disc 854 move the first protruding tooth groove rod 853 to the second protruding tooth groove. The second protruding tooth groove is engaged, so that the inner movable block 852 is fixed. At this time, the inner movable block 852 moves to the bottom of the guide hole. Correspondingly, the horizontal pull rod 847 drives the vertical pull rod 822 to pull the first pull ring body 821 in the upper cap sleeve 82 downward, so that the first pull ring body 821 can be attached to the second pull ring body 811. In this way, the entire protection module 8 is in a closed state. The protection module 8 cooperates with the coupling 62 to shield the output shaft, which has the effects of dustproof and liquid-proof. Especially in the production task of grinding and polishing a large number of workpieces, the use effect is improved, and the production cost is reduced.

[0052] At this time, the opposite lifting rod 831 is also separated from the other end of the inverted T-shaped insertion rod 858, so that the spring telescopic member 857 is selectively inserted into the insertion hole of the transverse pull rod member 847, and the transverse pull rod member 847 is further fixed, so as to prevent the transverse pull rod member 847 from moving transversely.
