Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to a buffer mechanism for a machine tool door lock. Background Technique

[0002] A numerically controlled machine tool refers to a machine that manufactures machines, also known as a machine tool or a tool machine, and is commonly referred to as a machine tool for short. It is generally divided into metal cutting machine tools, forging machine tools, and woodworking machine tools, etc. In modern mechanical manufacturing, there are many methods for machining mechanical parts. In addition to cutting, there are also casting, forging, welding, stamping, extrusion, etc. However, for parts with relatively high precision requirements and relatively fine surface roughness requirements, they generally need to be finally processed by cutting on a machine tool. When machining on a machine tool, it is necessary to install a protective door to prevent chips and coolant from splashing out.

[0003] Chinese Patent Publication No. CN218110152U discloses a buffer door stopper for a machine tool safety door, including a card seat and an impact column. A groove is provided on the card seat, and a buffer device is provided on the groove. During use, the impact column is stuck into the buffer device. The buffer device includes a buffer block, a slider, and a first spring. The buffer block slides on the groove. A convex block is provided on the side wall of the buffer block. The first spring is provided between the side wall of the groove and the side wall of the convex block. The slider slides on the side wall of the groove. The slider is in sliding tangency with the convex block. Spring two is provided on the top wall and the bottom wall of the groove. Spring two is provided between the groove and the slider.

A damping rod 3 for buffering is fixedly connected to the inner wall of the storage box 2. A load-bearing plate 4 for receiving force is clamped on the side of the damping rod 3. After the staff closes the machine tool door, the impact force generated by the closing is absorbed by the damping rod 3, and a part of the impact force is dispersed by the spring 11 on the outer surface of the damping rod 3. At the same time, with the cooperation of the limit rod 15 and the nut 16, the storage box 2 can be more conveniently installed on the inner wall of the limit shell 1, and it can also be more conveniently disassembled after it is damaged;

[0032] Please refer to Figures 2 to 7 , in order to more conveniently adjust the position of its push block 9, a sound-absorbing cotton 5 for reducing noise is fixedly connected to the side of the load-bearing plate 4. A threaded rod 8 for adjustment is inserted into the side of the limit shell 1. One end of the threaded rod 8 is threadedly connected with a push block 9 for pressing. A pad 10 for increasing friction is fixedly connected to the side of the push block 9. Anti-slip lines are provided on the outer surface of the pad 10. A placement groove 13 for storage is provided on the side of the limit shell 1. A card hole 14 for positioning is provided on the side of the limit shell 1. With the setting of the threaded rod 8, when the staff uses it, the position of the push block 9 can be adjusted more conveniently, so that the limit shell 1 can be installed on different machine tools. At the same time, with the setting of the pad 10, the friction between the push block 9 and the machine tool can be increased, making its installation more firm and stable. With the setting of the placement groove 13, the rubber strip 6 can be placed;

[0033] Please refer to Figures 1 to 4 , in order to more conveniently install and disassemble its stress pad 17, a rubber strip 6 for sealing is clamped on the inner side wall of the limit shell 1.

A positioning column 19 for fixing is inserted into the side of the limit shell 1. The positioning column 19 penetrates through one side of the limit shell 1 and is inserted into the inside of the connecting plate 18. An expansion rod 7 for adjustment is inserted into the side of the rubber strip 6. After the staff places the limit shell 1 on the upper end of the machine tool, the limit shell 1 can be protected by the stress pad 17 to prevent it from being damaged. At the same time, with the cooperation of the connecting plate 18 and the positioning column 19, it is convenient for the staff to disassemble and replace the damaged stress pad 17.

[0034] In the present utility model, the working steps of the device are as follows:

[0035] First, the staff snaps the limit shell 1 on the side of the machine tool, and then adjusts the threaded rod 8 according to the actual situation so that the push block 9 at one end reaches a suitable position, and fixes the limit shell 1 on the side of the machine tool. When the staff closes the machine tool door, at the same time, with the cooperation of the damping rod 3 and the sound-absorbing cotton 5 inside the storage box 2, the impact force generated when it is closed can be absorbed to protect it.
