DETAILED DESCRIPTION

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0022] according to Figure 1 - Figure 6 As shown, this embodiment provides a machine tool fixture installation mechanism, including a base plate 1, a plug-in seat, a plug-in rod 7 and a fixture body 10, the base plate 1 is provided with mounting holes 2 for plugging in the plug-in seat at equal intervals, the plug-in seat includes a middle frame 3, a front cover plate 4 and a rear cover plate 5, and the front and rear ends of the middle frame 3 are respectively installed with the front cover plate 4 and the rear cover plate 5 through fixing bolts;

[0023] A fixing hole 6 is provided in the middle of the middle frame 3 for the insertion rod 7 to pass through, and docking holes 9 are provided on both sides of the rod body of the insertion rod 7 for the inner insert block 8 to be inserted, and the top of the rod body is fixedly connected to the bottom of the clamp body 10;

[0024] Both sides of the middle frame 3 are provided with cavities 11 for installing the inner plug-in block 8 and the outer plug-in block 12, the lower end outer sides of the two cavities 11 are provided with first movable holes 13 for the extension and retraction of the outer plug-in block 12, and the middle end inner sides and middle end outer sides of the two cavities 11 are provided with second movable holes 14 for the extension and retraction of the inner plug-in block 8. Considering the existing installation mechanism, after a plurality of installation holes 2 are opened on the base plate 1, the installation worker fixes the clamp on the base plate 1 of the machine tool by tightening the screws and nuts. However, since the process of tightening the screws and nuts needs to be operated one by one, the whole installation process is particularly cumbersome. The utility model will use the outer plug-in block 12 and the limit plate 15 to cooperate with each other to quickly fix the plug-in seat in the installation hole 2 on the base plate 1, and the inner plug-in block 8 inside the plug-in seat will contact the inner wall of the installation hole 2 after it contacts the plug-in rod 7. At this time, the clamp body 10 fixed on the top of the plug-in rod 7 will be fixed. The structure makes it time-consuming to replace the clamp body 10 when fixing it to the base plate 1, and the installation efficiency is improved. During installation, the clamp with the plug-in rod 7 fixed on the bottom is first inserted into the fixing hole 6 in the middle of the middle frame 3, and then the inner block 8 and the outer block 12 are pressed inwardly, so that the first return spring 21 and the second return spring 23 are compressed. At this time, the surface of the middle frame 3 and the side walls of the inner block 8 and the outer block 12 are in the same plane, and then the plug-in seat is inserted into the mounting hole 2. After the lower end of the side of the middle frame 3 penetrates to the lower end of the mounting hole 2, the outer block 12 is no longer squeezed. At this time, the second return spring 23 is reset, driving the outer block 12 to move out of the first movable hole 13. At this time, the plug-in seat will be clamped on the base plate 1 through the limit block and the outer block 12, thereby completing the quick installation process. In this process, since the inner block 8 is resisted by the inner wall of the mounting hole 2 tube, the position of the plug-in rod 7 will be fixed by the inner blocks 8 on both sides.

[0025] Limiting plates 15 are fixed to the upper ends of both sides of the middle frame 3, and a first protective pad 16 is bonded to the bottom of the limiting plate 15, and the bottom of the first protective pad 16 is in contact with the upper surface of the base plate 1. Considering that the plug-in socket is fixed by the limiting plate 15 and the external plug-in block 12, the limiting plate 15 needs to frequently contact the surface of the base plate 1. In order to prevent the formation of wounds, the first protective pad 16 will be used to protect the contact surface.

[0026] The top of the side wall of each mounting hole 2 is designed as an arc-shaped structure, and a second protective pad 17 for resisting the external plug-in block 12 is fixed to the outside of the bottom end of each mounting hole 2. The second protective pad 17 and the first protective pad 16 are both made of rubber. By providing the second protective pad 17, the contact surface between the base plate 1 and the external plug-in block 12 is protected, and the presence of the first protective pad 16 and the second protective pad 17 will fill the gap and improve stability.

[0027] A guide column 18 is fixed inside each outer second movable hole 14. The guide column 18 passes through and is connected to a guide groove 19 provided inside the insert block 8. A groove for installing a ball 20 is provided on the end side wall surface of the insert block 8. The guide column 18 cooperates with the guide groove 19 to guide the extension and contraction of the insert block 8, thereby preventing the situation in which position deviation occurs during movement due to the lack of a guide structure. Position deviation will be detrimental to the installation of the insert block 8 and the docking hole 9.

[0028] A first return spring 21 is sleeved on the outside of the tail end of the insert block 8, and both ends of the second return spring 23 are in contact between the insert block 8 and the second movable hole 14. The internal shape of the second movable hole 14 is a rectangular structure design. The first return spring 21 is provided to reset the insert block 8. When the insert block 8 is no longer squeezed laterally, the first return spring 21 will be used to reset it.

[0029] A mounting seat 22 is fixedly installed inside the two cavities 11, and a second return spring 23 is abutted between the mounting seat 22 and the external plug-in block 12. The second return spring 23 is provided to reset the external plug-in block 12, so that after the second return spring 23 is detached from the mounting hole 2, the second return spring 23 will be used to complete the outward expansion return process.

[0030] The above shows and describes the basic principles, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only for explaining the principles of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
