Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses parts processing technology, and relates to a grinding machine for micro metal parts for eyeglasses, particularly a quick-release mechanism for the material gate in an eyeglasses hinge grinding machine. Background Technology

[0002] Eyeglass hinges are one of the accessories for eyeglasses, usually made of stamped metal, and their surfaces have burrs that need to be deburred. Currently, the accessories are usually placed in a grinding machine for deburring. However, due to the small size and light weight of eyeglass hinges and other accessories, the accessories and abrasive mixture are not fully mixed when tumbling inside the grinding machine's drum, resulting in low grinding effect and efficiency.

[0003] Chinese patent (application number: CN202323150643.8) discloses a drum-type grinder that performs secondary grinding by setting a guide plate. Chinese patent (application number: CN201320401387.2) discloses a drum-type grinder with long strip-shaped ribs set on the inner wall of the drum. However, the width of the ribs is limited. They improve the mixing efficiency to a certain extent, but cannot solve the problem of the micro-parts needing to be fully mixed, and the improvement effect is not obvious.

[0004] In addition, the material gates of these traditional grinding mill drums are often closed by a latch, which often fails to seal well due to insufficient locking force. Some use locking screws to close and lock the material gate, but the closing speed is slow due to the time it takes for the screws to turn. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a quick-release mechanism for the material gate in an eyeglass hinge grinding machine, thereby improving the sealing effect of the roller material gate during closure and the efficiency of opening and closing.

[0006] The objective of this utility model can be achieved through the following technical solution: A quick-release mechanism for the material gate in a spectacle hinge grinding machine includes a frame, a housing fixed on the frame, a roller rotatably mounted on the frame, the roller being connected to a transmission mechanism that enables its rotation, a spiral impeller fixed inside the roller, a material inlet on the roller wall, and a material gate at the material inlet. The roller comprises a cylindrical body and end caps on both sides of the cylindrical body. The cylindrical body is hexagonal prism-shaped, and the end caps are hexagonal frustum-shaped. The cylindrical body and the two end caps form a sealed cylindrical cavity. The material gate is fixed to the material inlet by a quick-release mechanism. The quick-release mechanism includes two vertical plates, one and two, respectively fixed on both sides of the cylindrical body. The first vertical plate has a central hole, and the second vertical plate has a central hole. The central hole is fitted with... The quick-release mechanism includes an eccentric ring 1 with an eccentric hole 1. A locking screw 1 is provided at the end of the vertical plate 1 to lock the eccentric ring 1 within the central hole 1. An eccentric ring 2 with an eccentric hole 2 is assembled within the central hole 2. The vertical plate 2 is provided at the end to lock the eccentric ring 2 within the central hole 2. The quick-release mechanism also includes an eccentric push rod. The eccentric push rod includes a base shaft and eccentric shaft 1 and eccentric shaft 2 respectively fixed on both sides of the base shaft. Eccentric shaft 1 and eccentric shaft 2 are coaxial and eccentric to the axis of the base shaft. Eccentric shaft 1 is rotatably disposed within the eccentric hole 1, and eccentric shaft 2 is rotatably disposed within the eccentric hole 2. A lever is fixed to the base shaft. When the lever is rotated, the base shaft can be brought into close contact with or separated from the material gate, thereby fixing or separating the material gate from the material inlet.

[0007] A screw is fixed to the outside of the cylinder on the side opposite to the feed inlet, and a balance block is screwed onto the screw.

[0008] The aforementioned material gate is fixed with pad block one and pad block two.

[0009] The aforementioned material gate is fixed with a handle.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] In this invention, the material gate is fixed to the material inlet via a quick-release mechanism. By moving the lever, the eccentric push rod can be quickly brought close to the material gate, and a large pre-tightening force can be applied to the material gate to achieve a good sealing effect. At the same time, the lever can be rotated back to disassemble the material gate. It has the advantages of simple structure and convenient disassembly. Attached Figure Description

[0020] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0021] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a quick-release mechanism for the material gate in a glasses hinge grinding machine is disclosed. The grinding machine includes a frame 1, a housing 2 fixed on the frame 1, a roller 3 rotatably mounted on the frame 1, the roller 3 being connected to a transmission mechanism that enables it to rotate, a spiral impeller 4 fixed inside the roller 3, a material inlet 5 opened on the cylinder wall of the roller 3, a material gate 6 provided at the material inlet 5, a drain outlet 7 opened on the cylinder wall of the roller 3, a filter screen 8 provided at the drain outlet 7, and a gate 9 for sealing the drain outlet 7.

[0022] Its working principle is as follows: Open the material gate 6, pour the hinge parts and abrasive mixture into the drum 3 through the material inlet 5, and then close the material gate 6. The transmission mechanism causes the drum 3 to rotate, and the parts and abrasive mixture inside the drum 3 tumbles at high speed. The tumbling and rising parts and mixture hit the spiral impeller 4, and the wheel blades of the spiral impeller improve the grinding efficiency and effect. After grinding, stop the rotation of the drum 3, open the gate 9, and then start the rotation of the drum 3 again to spin dry the abrasive mixture inside the drum 3. The water is discharged from the drain outlet 7. In this embodiment, the transmission mechanism includes a motor fixed on the frame 1. The drum 3 is rotatably mounted on the frame 1 via a shaft, and the motor drives the drum 3 to rotate through a belt and pulley transmission. The two ends of the shaft of the spiral impeller 4 are respectively fixed to the two side walls inside the drum 3.

[0023] The roller 3 includes a cylinder body 3a and end caps 3b on both sides of the cylinder body 3a. The cylinder body 3a is hexagonal prism-shaped, and the end caps 3b are hexagonal frustum-shaped. The cylinder body 3a and the two end caps 3b form a sealed cylinder cavity. The material gate 6 is fixed to the material inlet 5 by a quick-release mechanism. Figure 5 and Figure 6 As shown, the quick-release mechanism includes a first vertical plate 10 and a second vertical plate 11 fixed to both sides of the cylinder body 3a. The first vertical plate 10 has a central hole 10a, and the second vertical plate 11 has a central hole 11a. An eccentric ring 12 is fitted inside the central hole 10a. In this embodiment, a clearance fit is used. The eccentric ring 12 has an eccentric hole 12a. The end of the first vertical plate 10 is provided with a locking screw 13 to lock the eccentric ring 12 in the central hole 10a. An eccentric ring 14 is fitted inside the central hole 11a. In this embodiment, a clearance fit is used. The eccentric ring 14 has an eccentric hole 14a. The end of the second vertical plate 11 is provided with a locking screw 13 to lock the eccentric ring 14 in the central hole 10a. The locking screw 15 is locked in the center hole 11a. The quick release mechanism also includes an eccentric push rod 16. The eccentric push rod 16 includes a base shaft 16a and eccentric shafts 16b and 16c respectively fixed on both sides of the base shaft 16a. Eccentric shafts 16b and 16c are coaxial and eccentric to the axis of the base shaft 16a. Eccentric shaft 16b is rotatably disposed in eccentric hole 12a and eccentric shaft 16c is rotatably disposed in eccentric hole 14a. A lever 17 is fixed to the base shaft 16a. When the lever 17 is rotated, the base shaft 16a can be brought close to or separated from the material gate 6, thereby fixing or separating the material gate 6 from the material outlet 5.

[0024] After the material gate 6 closes the material inlet 5, the principle of the quick-release mechanism of the material gate 6 is as follows: because the eccentric shaft 16b and eccentric shaft 16c are eccentric to the base shaft 16a, rotating the lever 17 causes the bottom surface of the base shaft 16a to be locked against the top surface of the material gate 6, and is fixed by friction. To better achieve this function, the distance between the base shaft 16a and the material gate 6 can be adjusted by rotating the eccentric ring 12 and eccentric ring 14. Rotating the lever 17 makes the base shaft 16a tightly locked against the top surface of the material gate 6, achieving close fixation. After the eccentric ring 12 and eccentric ring 14 are adjusted by rotation, they are fixed by locking screw 13 and locking screw 15. When it is necessary to open the material gate 6, rotate the lever 17 to separate the base shaft 16a from the surface of the material gate 6. Move the eccentric push rod 16 axially to successively retract the eccentric shaft 16b and eccentric shaft 16c from the eccentric hole 12a and eccentric hole 14a, thus opening the material gate 6. In this embodiment, a number of levers are evenly distributed and fixed along the circumference of the inner wall of the drum 3 body 3a. The levers are rectangular and fixed along the axial direction of the drum 3. There are 6 levers in total, with one lever fixed on each hexagonal prism face, which improves the stirring effect of the grinding agent mixture on the accessories when the drum 3 rotates.

[0025] The drain outlet 7 has a stepped groove, and the filter screen 8 is fixed in the stepped groove. A first stop bar 18 and a second stop bar 19 are hinged to both sides of the drain outlet 7, and the gate 9 is enclosed in the stepped groove. The gate 9 is assembled in the stepped groove, and then fixed by rotating the first stop bar 18 and the second stop bar 19.

[0026] A support 20 is fixed on the housing 2, and an arc-shaped baffle 21 is hinged to the support 20. When dehydrating the mixture of parts after grinding, the baffle 21 is rotated so that it is above the drain outlet 7, which blocks the water that is thrown out and prevents splashing.

[0027] A screw 22 is fixed to the outside of the cylinder body 3a on the side opposite to the feed inlet 5. A balance block 23 is screwed onto the screw 22. Rotating the balance block 23 adjusts the dynamic balance, making the drum 3 run smoothly and reducing vibration.

[0028] The material gate 6 is fixed with pad 1 24 and pad 2 25 to prevent scratches on the material gate 6 and to provide protection.

[0029] The material gate 6 is fixed with a handle 26 for easy handling.

[0030] like Figure 7 As shown, the gate 9 is fixed with a handle 27 for easy handling.
