Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of fixing tooling, in particular to a fixing tooling for machining an engine tension wheel shell. Background Art
[0002] With the rapid development of automobiles, belt tensioner devices have become an indispensable part of automobile transmission systems. Belt tensioner devices are often composed of tensioner wheels, belts, etc. The tensioner housing is also an important component of the tensioner wheel. Considering the reliability and accuracy of the housing installed on the tensioner wheel, a tool that can fix the housing is needed to machine it. Existing fixing tools usually use cylinders to directly contact the housing, but this fixing method cannot control the clamping force well. A large clamping force can easily damage the housing, and a small clamping force can have a poor clamping effect on the housing. Therefore, we propose a fixing tool for machining the engine tensioner housing to solve the above-mentioned problems. Utility Model Content

[0021] Example
[0022] See also Figure 1-4 A fixing tool for machining an engine tension wheel housing comprises a workbench 1, a fixing plate 2 is fixedly installed on the top of the workbench 1, a through hole is opened in the middle area of the fixing plate 2, a screw 4 is arranged inside the through hole, a support plate 3 is fixedly installed on the top of the workbench 1, the support plate 3 and the screw 4 are screwed together, a slide bar 5 is rotatably installed on the other end of the screw 4, two connecting rods 6 are fixedly installed on the top of the slide bar 5, a clamping plate 7 is rotatably installed on the bottom end of each connecting rod 6, and the outer wall of each clamping plate 7 is fixedly connected to the outer wall of the fixing plate 2 through a spring 8. A plurality of through holes 9 are provided at the top of the workbench 1, and a plurality of fixing mechanisms are arranged on the through holes 9; a handle 12 is fixedly installed at one end of the screw rod 4, and by installing the handle 12, the screw rod 4 can be easily rotated; a guard plate 13 is fixedly installed at the top of the workbench 1, and by installing the guard plate 13, the outer shell processed at the top of the workbench 1 can be limited; a collecting cover 15 is fixedly installed at the bottom end of the workbench 1, and a door 16 is rotatably installed at the bottom end of the collecting cover 15, and by installing the collecting cover 15, the debris generated by the processing of the through hole 9 can be collected.
[0023] See also Figure 1-4 The fixing mechanism includes a fixing column 10, which is screwed with the through hole 9. A limiting plate 11 is fixedly installed at the bottom end of the fixing column 10. The engine tension wheel housing is machined and fixed with a tool. The sliding rod 5, the connecting rod 6 and the clamping plate 7 are synchronously driven to move laterally while rotating the screw 4, and then the housing is clamped and fixed by the two clamping plates 7 and the fixing column 10, and the clamping plate 7 is buffered by the spring 8. The two fixing columns 10 contact the outer wall of the clamping plate 7, and then the two clamping plates 7 are limited, and then the force of clamping the housing by the two clamping plates 7 is effectively buffered, so as to avoid certain damage to the housing when the two clamping plates 7 are clamped on the housing, thereby improving the stability effect of the device when clamping the housing, and improving practicality.

[0025] In summary, when the engine tension wheel housing machining fixing tool is in use, the fixing column 10 is screwed into one of the through holes 9, and one end of the housing is tightly fitted with the outer wall of the fixing column 10. The handle 12 is rotated while the screw 4 is synchronously driven to rotate. Since the screw 4 and the support plate 3 are screwed, the screw 4 is rotated while the sliding rod 5, the connecting rod 6 and the two clamping plates 7 are synchronously driven to move horizontally. The outer walls of the two clamping plates 7 are in contact with the housing, and the housing is clamped. The two clamping plates 7 are buffered by the spring 8. After the housing is fixed, the two fixing columns 10 are rotated to fit the outer walls of the two clamping plates 7, so that the housing is fixed by the two clamping plates 7 and one fixing column 10.
