Description

Technical Field

[0001] The utility model relates to the technical field of machine tool front doors, in particular to a structure that facilitates the installation and fine adjustment of a lower pulley on a machine tool front door. Background Art

[0002] The front door of a CNC machine tool is a protective device that is used to protect external operators during machine tool processing and to facilitate observation by operators.

[0003] After the front door is assembled on site, it may be uneven. This problem can usually be solved by adjusting the position of the lower pulley on the front door. However, the lower pulley on the front door only has long holes on the side for up and down adjustment. When the lower pulley is adjusted to the specified position, the position of the lower pulley may be offset when the lower pulley is installed. After the lower pulley is installed, the lower pulley is out of the specified position and the position will still be uneven, which will cause the on-site assemblers to spend a long time debugging and installing, which is time-consuming and labor-intensive. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a structure that facilitates the installation and fine adjustment of the lower pulley of the front door of a machine tool. The specific technical solution is as follows:

[0005] A structure for facilitating fine-tuning the installation of a pulley under a front door of a machine tool, comprising a front door body, wherein sliding assemblies are arranged on both sides of the bottom end of the front door body, wherein the sliding assembly comprises a pulley frame and a pulley rotatably connected to the inner side of the pulley frame, wherein a fine-tuning assembly is arranged above the sliding assembly, wherein the fine-tuning assembly comprises a first nut arranged on both sides of the top of the pulley and a second nut arranged in the middle of the top of the pulley, wherein a first screw is connected to the inner thread of the first nut, and the bottom end of the first screw is connected to the top end of the pulley frame, wherein a second screw is connected to the inner thread of the second nut, and the bottom end of the second screw is fixedly connected to a limiting plate.

[0006] As an improvement of the above technical solution: two guide openings are opened on one side of the bottom end of the front door body close to the sliding assembly, a guide block is slidably connected in the guide opening, and one end of the guide block is fixedly connected to one side of the pulley frame.

[0007] As an improvement of the above technical solution: a buffer gasket is fixedly connected to one side of the limit plate close to the pulley frame.

[0008] As an improvement of the above technical solution: a second opening and two first openings are opened at the top of the front door body, each of the first screws is fixedly connected to the bottom end of the front door body and is coaxially arranged with one of the first openings, and the second screw is fixedly connected to the bottom end of the front door body and is coaxially arranged with the first openings.

[0009] Beneficial effects of the utility model:

[0010] During the on-site assembly of the front door, the position of the pulley is fine-tuned according to the height of the sliding component and the ground of the site. The specific fine-tuning process is that by turning the first screw above the pulley frame, it drives the upward or downward movement, so that the bottom end surface of the pulley contacts the ground of the site, so that the pulley is initially fixed to the specified position, and then the second screw is turned to drive the limit plate to move downward, so that the buffer gasket contacts the top end surface of the pulley frame, and then the pulley frame and the front door body are fixedly installed by bolts, so that the pulley is stably installed at the specified required position at the bottom end of the front door, avoiding the occurrence of unevenness after the pulley is installed, thereby greatly reducing the assembly and debugging time and saving the work intensity of the assemblers.

[0018] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0019] Example

[0020] A structure that facilitates the installation and fine adjustment of the lower pulley under the front door of the machine tool, please refer to Figure 1-Figure 6 , a structure for facilitating fine-tuning the installation of a lower pulley under a front door of a machine tool, comprising a front door body 1, the front door body 1 being arranged in an L shape, a sliding assembly 100 being arranged on both sides of the bottom end of the front door body 1, the sliding assembly 100 comprising a pulley frame 3 and a pulley 31 rotatably connected to the inner side of the pulley frame 3, a fine-tuning assembly being arranged above the sliding assembly 100, the fine-tuning assembly comprising a first nut 21 arranged on both sides of the top of the pulley 31 and a second nut 41 arranged in the middle of the top of the pulley 31, the first nut 21 being internally threadedly connected with a first screw 2, the bottom end of the first screw 2 being connected to the top of the pulley frame 3, the second nut 41 being internally threadedly connected with a second screw 4, the bottom end of the second screw 4 being fixedly connected with a limiting plate 42, further, the tops of the first screw 2 and the second screw 4 are both fixedly connected with a rotating block to facilitate their rotation.

[0021] In an alternative embodiment: refer to Figure 4 and Figure 6 Two guide openings 11 are provided at one side of the bottom end of the front door body 1 close to the sliding assembly 100, and the front door body 1 is opened in the vertical direction. A guide block 32 is slidably connected in the guide opening 11, and one end of the guide block 32 is fixedly connected to one side of the pulley frame 3. Specifically, when the first screw 2 is rotated, the guide block 32 on one side of the pulley frame 3 slides in the guide opening 11, thereby limiting the pulley frame 3, so that the pulley frame 3 can drive the pulley 31 to be stably adjusted up and down.

[0022] In an optional embodiment: a buffer gasket 43 is fixedly connected to one side of the limit plate 42 close to the pulley frame 3. Specifically, the buffer gasket 43 can be made of rubber material, and the buffer gasket 43 plays a buffering role on the pulley frame 3.

[0023] In an optional embodiment: a second through opening 12 and two first through openings 10 are opened at the top of the front door body 1, each of the first screws 2 is fixedly connected to the bottom end of the front door body 1 and is coaxially arranged with one of the first through openings 10, and the second screw 4 is fixedly connected to the bottom end of the front door body 1 and is coaxially arranged with the first through openings 10. Specifically, the first through opening 10 and the second through opening 12 both pass through one side of the bottom end of the front door body 1, and the first through opening 10 and the second through opening 12 facilitate the operation of the first screw 2 and the second screw 4.

[0024] The first screw 2 is rotated to move the limit plate 42 downward, so that the buffer gasket 43 is in conflict with the top surface of the pulley frame 3, and then the pulley frame 3 is fixedly installed with the front door body 1 by bolts, etc. In the process of fixing and installing the pulley frame 3 with the front door body 1, the pulley frame 3 is tightly contacted with the buffer gasket 43 to avoid the pulley frame 3 being shaken and causing the pulley frame 3 to be out of position when the pulley frame 3 is installed by electric means, so that the pulley 31 is stably installed at the specified required position at the bottom end of the front door, and the uneven situation after the pulley 31 is installed is avoided, thereby greatly reducing the assembly and debugging time and saving the work intensity of the assemblers.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
