Technical Field

[0001] The utility model relates to the technical field of operating mechanism maintenance tooling, in particular to a protective fixing tooling for a compression spring pressing device of an operating mechanism. Background Art

[0002] In the process of compressing the disc spring of the operating mechanism through the pressing device 40, the pressing device will vibrate during the continuous pressing process, so that the pressing device 40 placed on the workbench 50 will move, which will cause the risk of the pressing device 40 falling, and the control handle of the pressing device 40 will also automatically move during the vibration process. Therefore, every time the pressing device 40 is operated, one person is required to stabilize the pressing device 40 and hold the control handle of the pressing device 40 to prevent the pressing device 40 from falling and sudden pressure release, resulting in a safety accident caused by the instantaneous release of the disc spring elastic force. The existing method requires one person during the pressing process, so a protective fixing tool for the pressing device of the operating mechanism compression spring is designed.

[0021] See also Figure 1-3 A protective fixing tool for a pressure spring pressing device of an operating mechanism includes a fixing seat 10, a positioning device 20 and a switch limiting device 30. The fixing seat 10 includes a bottom plate 11, and the positioning devices 20 are respectively installed on the opposite sides of the bottom plate 11. A fixing column 13 and a switch limiting device 30 for limiting the position of a control handle of a pressing device 40 are installed on the upper side of the bottom plate 11. The fixing seat 10 is used to limit the pressing device 40, the positioning device 20 is used to position and fix the fixing seat 10 and the workbench 50, and the switch limiting device 30 is used to limit the control handle 42 of the pressing device 40, so that during the pressing process, there is no need to manually hold the pressing device.

[0022] For details, see Figure 1 , 2 The front and rear sides of the lower end of the pressing device 40 are respectively provided with limiting holes 41. When in use, the two fixing columns 13 on the bottom plate 11 are respectively inserted into the two limiting holes 41 for limiting.

[0023] Furthermore, longitudinal plates 12 are arranged around the bottom plate 11 so that the fixing seat 10 is disc-shaped. When oil leaks, it will be collected in the disc-shaped fixing seat 10.

[0024] In one solution, the positioning device 20 includes two hooks 21, one of which is screwed with a bolt 23. The two hooks 21 can be welded to the side or bottom of the fixing base 10 respectively. Figure 3 , push from one side of the workbench 50, insert the hook 21 into the table surface of the workbench 50, and then tighten the bolt 23, which abuts against the side or bottom of the workbench 50, so as to position the fixing seat 10. Figure 1 , 2 In the figure, it is shown that the bolt 23 is screwed on the hook 21 horizontally, so when installing, the bolt 23 abuts against the side of the workbench 50; when the bolt 23 is screwed on the hook 21 longitudinally and upwardly, when installing, the bolt 23 abuts against the top of the workbench 50. The bolt 23 is preferably a hand-tightened bolt.

[0025] For further information, see Figure 1 , 2 The two hooks 21 of the positioning device 20 are respectively mounted on the connecting rod 22, and the connecting rod 22 is connected to the fixing seat 10. Specifically, the connecting rod 22 adopts an angle steel structure, and the connecting rod 22 is welded to the longitudinal plate 12 of the fixing seat 10, so as to improve the structural strength of the fixing seat 10, and also make the fixing seat 10 directly fit and contact with the workbench 50, so as to improve the stability of the fixing seat 10.

[0026] In one solution, the switch limit device 30 includes a screw rod 31, a pressure plate 32 is mounted on the screw rod 31, and a nut 33 is screwed and mounted on the screw rod 31 at the upper side of the pressure plate 32. The height of the pressure plate 32 is controlled by the nut 33, so that the pressure plate 32 presses down the control handle 42, thereby limiting the position of the control handle 42. In this solution, the pressure plate 32 is sleeved on the screw rod 31 through a hole, and the pressure plate 32 can be a circular plate, so that there is no fear that the pressure plate 32 rotates under vibration and loosens the control handle 42. When the pressure plate 32 adopts Figure 1 In the structure shown in , nuts can also be installed on the screw rod 31 at the upper and lower sides of the pressing plate 32, and the nuts on both sides abut against the pressing plate 32 at the same time, thereby limiting the pressing plate 32.

[0027] It should be noted that the nut 33 is a locking nut, which has a plastic ring inside to prevent the nut from loosening under vibration.

[0028] Furthermore, the switch limit device 30 further includes a support rod 34, which is fixed on the bottom plate 11, and the screw rod 31 is arranged at the upper end of the support rod 34. Since the screw rod 31 is relatively long and has poor stability when in use, the support rod 34 is arranged, and the diameter of the support rod 34 is larger than the diameter of the screw rod 31. The support rod 34 and the screw rod 31 can be integrated, or the support rod 34 can be a tubular structure, and the screw rod 31 is threadedly fixed in the tubular structure of the support rod 34.

[0029] The working principle or action process of the utility model is as follows:

[0030] When using, see Figure 3 First, push the tooling from one side of the workbench 50, insert the hook 21 into the table surface of the workbench 50, and then tighten the bolt 23 to position the tooling.

[0031] The pressing device 40 is placed on the bottom plate 11 of the fixing seat 10 , and the two fixing columns 13 on the bottom plate 11 are respectively inserted into the two limiting holes 41 at the lower ends of the two pressing devices 40 .

[0032] The height of the pressing plate 32 is controlled by the nut 33 so that the pressing plate 32 presses down the control handle 42, thereby limiting the position of the control handle 42 to prevent the control handle 42 from automatically operating during pressing, thereby causing safety risks.
