Problems solved by technology

After traditional centerless grinding, the roughness of the alloy teeth cannot meet the requirements, and there is a risk of tooth loss if the alloy teeth are directly installed into the gear; Clean, it will form corrosion on the surface of alloy teeth, affecting the geometric strength of alloy teeth
[0003] The existing patent number is CN202110632088.9 A method for processing cemented carbide teeth of mining drill bits, including a base plate, a placing device, a grinding device and a polishing device, the upper end of the base plate is equipped with a placing device, and the upper end of the placing device is equipped with a grinding device. There is a polishing device behind the grinding device; it is disclosed that the surface and arc surface of the drill bit are polished and polished at the same time, the alloy teeth of the drill bit need to be positioned in the placement device one by one, the positioning structure is complicated, and the positioning processing of the alloy teeth for small pieces cannot be realized; And the grinding and polishing are processed at the same time, which cannot effectively remove the internal stress in the alloy teeth due to the grinding process, which affects the service life of the alloy teeth

Embodiment

[0029] refer to Figure 1-3 As shown, this embodiment is a drum-type cleaning alloy tooth polishing machine, including a support plate 1, a first drive device 2 that drives the support plate 1 to tilt and rotate relative to the horizontal direction, and a rotating device that is horizontally arranged on the support plate 1. The cleaning drum 3 and the drainage assembly 4 arranged on the outer wall of the cleaning drum 3; the cleaning drum 3 includes a first cylinder 31 close to the driving end, a second cylinder 32 connecting the first cylinder 31 and forming a washing chamber, and the cleaning drum 3 is coated with a resin coating in the inner wall.

[0030] The support plate 1 is a rectangular plate body, the bottom of the support plate 1 is provided with a bearing mandrel 11 arranged in the horizontal direction, the two sides below the support plate 1 are symmetrically provided with bearing sleeves 12 sleeved on the bearing mandrel 11, and the bearing sleeves 12 It can be ...

Embodiment 2

[0036] The present embodiment is a drum-type cleaning alloy tooth polishing method, comprising the following steps:

[0037] Grinding the alloy teeth by machining with a centerless grinder;

[0038] The polished batches of alloy teeth are put into the cleaning drum 3, an appropriate amount is located in the washing chamber, and the support plate 1 is in a horizontal state, so that the batches of alloy teeth can enter through the feeding port 33;

[0039] The control panel sets the operating parameters of the cleaning drum 3, starts the feeding mode, and the first driving device 2 controls the tilting state of the support plate 1, so that the feeding port 33 is set upward;

[0040] Clean water is injected into the cleaning drum 3, and the level of the clean water is lower than the feeding port 33;

[0041] The control panel starts the second driving device 5 according to the set parameters, starts the polishing mode, and the cleaning drum 3 rotates to perform stirring and poli...

Abstract

The invention discloses a drum-type cleaning alloy tooth polishing machine. The drum-type cleaning alloy tooth polishing machine comprises a supporting plate, a first driving device for driving the supporting plate to obliquely rotate relative to the horizontal direction, a cleaning drum horizontally arranged on the supporting plate and rotationally arranged, and a drainage assembly arranged on the outer wall of the cleaning drum. The cleaning roller comprises a first roller body close to the driving end and a second roller body which is connected with the first roller body and forms a material cleaning cavity with the first roller body, and the inner wall of the cleaning roller is coated with a resin coating. Polishing treatment is carried out on the ground alloy teeth, internal stress caused by grinding of the alloy teeth is removed in a throwing and stirring mode, the service life of the alloy teeth is prolonged, the requirement for the roughness of the alloy teeth is met, and the alloy teeth can be accurately assembled with cones.

Description

technical field [0001] The invention belongs to the technical field of alloy tooth polishing, and in particular relates to a drum type cleaning alloy tooth polishing machine and a polishing method thereof. Background technique [0002] The assembly structure of the roller cone drill usually includes a cone, and the surface of the cone is provided with a tooth hole, and the alloy teeth are pressed into the tooth holes of the cone through interference fit. Therefore, the surface roughness of the alloy teeth requires higher. After traditional centerless grinding, the roughness of the alloy teeth cannot meet the requirements, and there is a risk of tooth loss if the alloy teeth are directly installed into the gear; Cleaning will cause corrosion on the surface of the alloy teeth, affecting the geometric strength of the alloy teeth. [0003] The existing patent number is CN202110632088.9 A method for processing cemented carbide teeth of mining drill bits, including a base plate,...
