DETAILED DESCRIPTION

[0045] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0046] Reference Figure 1-Figure 6 A surface polishing and grinding device for the production and processing of hardware pipe fittings includes a body 1, on which a first mounting frame 2, a second mounting frame 3, a mounting gear 4, a rotating disk 5, a clamping mechanism, a driving mechanism and a grinding mechanism are arranged. The components are arranged as follows:

[0047] The two first mounting frames 2 are symmetrically integrated on the machine body 1 , the second mounting frame 3 is symmetrically integrated on the machine body 1 , and the second mounting frame 3 is arranged at the inner end position of the first mounting frame 2 .

[0048] The mounting gear 4 is rotatably mounted on the first mounting frame 2 , and the rotating disk 5 is rotatably mounted on the second mounting frame 3 . The mounting gear 4 and the rotating disk 5 are concentrically arranged.

[0049] The clamping mechanism is arranged on the mounting gear 4 and the rotating disk 5, and the clamping mechanism is used to clamp and limit the inner wall of the hardware pipe fitting;

[0050] A further implementation method is that the clamping mechanism includes a clamping member 6, a first cylinder 7 and a traction rod 8, and each component is arranged as follows:

[0051] The clamping member 6 is slidably mounted on the rotating disk 5, and at least two clamping members 6 are provided. The rotating disk 5 is provided with a long guide hole for the slidably mounted clamping member 6. The outer end surface of the clamping member 6 is an arc-shaped structure. It should be noted that a rubber pad is fixedly mounted on the outer end of the clamping member 6. The friction coefficient between the clamping member 6 and the hardware pipe fitting can be enhanced by the rubber pad, and the flexibility of the rubber pad is utilized so that the clamping member 6 can flexibly clamp the hardware pipe fitting through the rubber pad.

[0052] The first cylinder 7 is fixedly mounted on the mounting gear 4;

[0053] The traction rod 8 is connected between the first cylinder 7 and the clamping member 6. Both ends of the traction rod 8 are pin-connected to the output end of the first cylinder 7 and the end of the clamping member 6 away from the grinding mechanism. When the first cylinder 7 moves, one end of the traction rod 8 performs horizontal linear motion. Since the clamping member 6 is restricted by the guide long hole, the clamping member 6 can only perform radial motion based on the center of the rotating disk 5. Therefore, the other end of the traction rod 8 is restricted by the clamping member 6 and can only perform radial motion.

[0054] The driving mechanism is arranged in the machine body 1, and the driving mechanism drives the clamping mechanism to rotate through the installation gear 4 and drives the hardware pipe fittings to rotate intermittently;

[0055] A further implementation method is that the driving mechanism includes a mounting slot 9, a motor 10, a rotating shaft 11, an incomplete gear 12 and a driven gear 13, and each component is arranged as follows:

[0056] The mounting slot 9 is provided on the body 1;

[0057] The motor 10 is fixedly installed in the installation slot 9, and the rotating shaft 11 is fixedly connected to the output end of the motor 10, providing installation space for the motor 10 and the rotating shaft 11;

[0058] The incomplete gear 12 is fixedly mounted on the rotating shaft 11, and the driven gear 13 is rotatably mounted on the first mounting frame 2. The incomplete gear 12 and the driven gear 13 are meshed and connected with each other, and the driven gear 13 is meshed and connected with the mounting gear 4. It should be noted that after the incomplete gear 12 rotates two circles, the driven gear 13 will be driven by the incomplete gear 12 to rotate one circle.

[0059] The grinding mechanism is arranged on the second mounting frame 3, and the grinding mechanism is used to grind the hardware pipe fittings at multiple angles;

[0060] A further implementation method is that the grinding mechanism includes a second cylinder 14, a mounting plate 15, an electric slide rail 16, a retractable grinding member 17 and a guide assembly, and each component is arranged as follows:

[0061] The second cylinder 14 is mounted on the second mounting frame 3, and both ends of the second cylinder 14 are pin-mounted on the second mounting frame 3 and the mounting plate 15, respectively. Four second cylinders 14 are provided, and two second cylinders 14 provided on the same second mounting frame 3 form a group. The two groups of second cylinders 14 work in opposite states. When the output end of one group of second cylinders 14 extends, the output end of the other group of second cylinders 14 contracts.

[0062] The mounting plate 15 is mounted on the output end of the second cylinder 14;

[0063] The electric slide rail 16 is fixedly arranged on the mounting plate 15, and the retractable grinding member 17 is matched with the electric slide rail 16. The mounting plate 15 is driven by the second cylinder 14 to adjust the angle, so that the mounting plate 15 drives the retractable grinding member 17 to adjust the angle through the electric slide rail 16, which helps to improve the flexibility of the retractable grinding member 17 during operation;

[0064] The guide assembly is arranged on the second mounting frame 3 and the mounting plate 15, and the guide assembly is used to guide and support the mounting plate 15;

[0065] A further implementation method is that the guide assembly includes a first guide slider 18, a second guide slider 19 and a connecting rod 20, and each component is arranged as follows:

[0066] The first guide slider 18 is slidably mounted on the second mounting frame 3, and the second guide slider 19 is slidably mounted on the side wall of the mounting plate 15. The sliding mounting method can be a slide groove or a slide rail. The specific implementation method is as follows:

[0067] When a slide groove is used, the slide groove is opened on the second mounting frame 3 and the mounting plate 15, and the first guide slider 18 and the second guide slider 19 are slidably mounted through the slide groove, which can reduce the mass required to be added to the second mounting frame 3 and the mounting plate 15 when the first guide slider 18 and the second guide slider 19 are arranged, and helps to reduce the load generated by adding the second mounting frame 3 and the mounting plate 15;

[0068] When a slide rail is used, the slide rail is fixedly connected to the second mounting frame 3 and the mounting plate 15, and the first guide slider 18 and the second guide slider 19 are slidably mounted by the slide rail, so that the second mounting frame 3 and the mounting plate 15 can be prevented from causing damage to the original structure of the second mounting frame 3 and the mounting plate 15 when the first guide slider 18 and the second guide slider 19 are set, which helps to ensure that the original structure of the second mounting frame 3 and the mounting plate 15 is not affected by the structure driven by the addition of the first guide slider 18 and the second guide slider 19;

[0069] The pins at both ends of the connecting rod 20 are connected to the first guide slider 18 and the second guide slider 19. Through the setting of the connecting rod 20, when the first guide slider 18 moves, the second guide slider 19 also moves simultaneously, so that the mounting plate 15 is guided and supported by four groups of the first guide slider 18, the second guide slider 19 and the connecting rod 20, which helps to ensure the stability of the mounting plate 15 when the angle is adjusted.

[0070] It should be noted that the specific models and specifications of the first cylinder 7, the second cylinder 14, the electric slide rail 16 and the retractable grinding member 17 need to be selected and determined according to the actual specifications of the device, and the specific selection calculation method adopts the existing technology in the field, so it is not repeated here.

[0071] The present invention can be explained by the following operation mode:

[0072] Put two hardware pipe fittings on the clamping piece 6, and the staff manually aligns the middle ends of the two hardware pipe fittings, and starts the first cylinder 7 to drive one end of the traction rod 8 to move linearly, and the other end of the traction rod 8 drives the clamping piece 6 to move radially in the guide long hole, and the clamping piece 6 squeezes and fixes the inner wall of the hardware pipe fitting;

[0073] The second cylinder 14 is started to drive the mounting plate 15 to perform angular deflection. The mounting plate 15 drives one end of the connecting rod 20 to perform linear motion through the second guide slider 19. The other end of the connecting rod 20 drives the first guide slider 18 to perform vertical motion. The mounting plate 15 drives the retractable grinding member 17 to perform angular deflection through the electric slide rail 16.

[0074] When the retractable grinding piece 17 and the hardware pipe fittings are against each other, the electric slide rail 16 is started, and the electric slide rail 16 drives the retractable grinding piece 17 to move horizontally, and the retractable grinding piece 17 performs grinding operation on the hardware pipe fittings. At the same time, the motor 10 is started, and the motor 10 drives the rotating shaft 11 to rotate, and the rotating shaft 11 drives the incomplete gear 12 to rotate, and the incomplete gear 12 drives the driven gear 13 to rotate intermittently, and the driven gear 13 drives the installation gear 4 to rotate intermittently, and the installation gear 4 drives the first cylinder 7 to rotate circumferentially, and drives the hardware pipe fittings to rotate intermittently through the clamping mechanism, and when the retractable grinding piece 17 contacts the hardware pipe fittings, the incomplete gear 12 does not mesh with the driven gear 13.

[0075] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
