Description

Technical Field

[0001] This utility model relates to the field of safety protection technology for CNC machine tools, and in particular to a safety protection structure for hydraulic CNC machine tools. Background Technology

[0002] A CNC machine tool is a machine tool controlled using computer numerical control technology. It is a product of the combination of traditional machine tools and computer technology. Through a computer system, it controls the motion axes, cutting feed, and speed to achieve the machining operation of the workpiece. Compared with traditional manual operation or mechanical control methods, CNC machine tools have a higher degree of automation and precision.

[0003] A search revealed a CNC machine tool protective device with publication number CN221065531U. When the workpiece is finished and the protective door needs to be opened, the insert rod is pulled away from the insertion hole, compressing the retaining ring and the return spring, causing the insert rod to disengage from the insertion hole. The handle can then be pulled to slide the protective door within the groove, thus opening the protective door. After the protective door slides a short distance, the insert rod can be released, and under the return force of the return spring, the ball bearing at the end of the insert rod contacts the protective door. When the protective door continues to slide until the groove aligns with another insertion hole, under the return force of the return spring, the insert rod re-inserts into the insertion hole, thereby fixing the protective door in place.

[0004] When using the device disclosed in this patent, one hand needs to pull the plug rod to release the protective door limit, and then pull the corresponding protective door with the other handle. This results in only one protective door being able to be opened at a time, which is not only cumbersome to operate, but also inefficient to open two protective doors. Utility Model Content

[0005] In response to the technical problem in existing patents that require one hand to pull the plug rod to release the protective door limit and then pull the corresponding protective door with the other handle, resulting in only one protective door being able to be opened at a time, which is not only cumbersome to operate but also inefficient to open two protective doors, this utility model provides a safety protection structure for hydraulic CNC machine tools.

[0006] The technical solution adopted by this utility model is: a safety protection structure for a hydraulic CNC machine tool, comprising:

[0007] The body cover has two guide rails on its inner wall, and one side of each guide rail has multiple positioning grooves along its length.

[0008] Two protective mechanisms are provided, each including a protective door that slides between the two guide rails, a fixed handle on one side of the protective door, and a limiting handle that slides elastically on one side of the protective door. The limiting handle slides within the fixed handle and corresponds to the positioning groove.

[0009] Furthermore, both the fixed handle and the limiting handle are U-shaped plate structures. The limiting handle has Z-shaped protrusions at both the top and bottom, which correspond to the positioning groove. The protective door has a Z-shaped hole on one side that corresponds to the Z-shaped protrusion. The Z-shaped protrusion slides in the Z-shaped hole, and a first spring damper is provided between the Z-shaped protrusion and the inner wall of the Z-shaped hole.

[0010] Furthermore, the body cover has an opening on one side, and the guide rail is an L-shaped plate structure. The relative inner heights of the two guide rails are the same as the bottom and top surfaces of the inner wall of the opening, respectively.

[0011] Furthermore, a baffle is slidably fitted on one side of the protective door, and a plurality of second spring dampers are provided on one side of the baffle. A polygonal limiting groove is provided on one side of the protective door, and a polygonal guide post is provided in the polygonal limiting groove. A guide hole corresponding to the polygonal guide post is provided on one side of the baffle. The baffle is slidably fitted onto the polygonal guide post through the guide hole. One end of the polygonal guide post is provided with a limiting outward flange. A Torx handle screw is rotatably fitted on one side of the protective door. The threaded end of the Torx handle screw passes through the protective door and is threadedly engaged with the polygonal guide post. A groove corresponding to the handle end of the Torx handle screw is provided on one side of the protective door.

[0012] The beneficial effects of this utility model are:

[0013] By setting fixed handles and limit handles, the limit handles inside the two fixed handles are slid out, thereby simultaneously releasing the limit of the two protective doors. The two protective doors are slid towards each other by pulling the two fixed handles, which improves the convenience and efficiency of opening the two protective doors.

[0014] By setting up a baffle and a second spring damper, it is easy to block the processing debris that splashes towards the protective door during processing by the baffle, and the impact force generated by the processing debris is buffered by the second spring damper, which helps to improve the service life of the protective door. At the same time, the baffle improves the protective effect of the protective door. Attached Figure Description

[0023] The following is in conjunction with the appendix Figure 1-4 The present invention will be further described below.

[0024] To address the problems existing in the background art, this application proposes the following technical solution:

[0025] A safety protection structure for a hydraulic CNC machine tool includes:

[0026] The body cover 1 has two guide rails 101 on its inner wall, and multiple positioning grooves 102 are provided on one side of the guide rails 101 along the length direction.

[0027] Two protective mechanisms 2, each including a protective door 200 that slides between two guide rails 101, a fixed handle 201 located on one side of the protective door 200, and a limiting handle 202 that slides elastically on one side of the protective door 200. The limiting handle 202 slides within the fixed handle 201 and corresponds to the positioning groove 102.

[0028] Furthermore, both the fixed handle 201 and the limiting handle 202 are U-shaped plate structures. The limiting handle 202 has Z-shaped protrusions 203 at both the upper and lower ends. The Z-shaped protrusions 203 correspond to the positioning groove 102. The protective door 200 has a Z-shaped hole 204 on one side that corresponds to the Z-shaped protrusions 203. The Z-shaped protrusions 203 slide in the Z-shaped hole 204. A first spring damper 205 is provided between the Z-shaped protrusions 203 and the inner wall of the Z-shaped hole 204.

[0029] Furthermore, an opening 103 is provided on one side of the body cover 1, and the guide rail 101 is an L-shaped plate structure. The relative inner heights of the two guide rails 101 are the same as the bottom and top surfaces of the inner wall of the opening 103, respectively, so as to avoid the guide rails 101 from affecting the opening 103.

[0030] Furthermore, a baffle 206 is slidably fitted on one side of the protective door 200. Multiple second spring dampers 207 are provided on one side of the baffle 206. A polygonal limiting groove 213 is provided on one side of the protective door 200, and a polygonal guide post 208 is provided within the polygonal limiting groove 213 to improve the stability of the polygonal guide post 208 installed on one side of the protective door 200. A guide hole 209 corresponding to the polygonal guide post 208 is provided on one side of the baffle 206. The baffle 206 is slidably fitted onto the polygonal guide post 208 through the guide hole 209, facilitating the sliding of the baffle 206 by the polygonal guide post 208. One end of the polygonal guide post 208 has a limiting outward tilt. Side 210 is provided to limit the sliding range of baffle 206. A rotatable screw 211 is provided on one side of the protective door 200. The threaded end of the screw 211 passes through the protective door 200 and is threaded into the polygonal guide post 208. A groove 212 corresponding to the handle end of the screw 211 is provided on one side of the protective door 200, which facilitates the baffle 206 to improve the protective effect of the protective door 200. Rotating the screw 211 releases the limit of the polygonal guide post 208, which allows the polygonal guide post 208, baffle 206 and second spring damper 207 to be disassembled, thus improving the replacement efficiency of baffle 206 and second spring damper 207.

[0031] Working principle: When it is necessary to open the protective door 200, hold the two fixed handles 201, and slide the limiting handle 202 inside the fixed handle 201. This causes the Z-shaped protrusion 203 to slide, compressing the first spring damper 205 and sliding it out of the positioning groove 102. This simultaneously releases the limiting position of the two protective doors 200. By pulling the two fixed handles 201, the two protective doors 200 slide towards each other, making it easier to open the two protective doors 200 quickly and simultaneously. This improves the convenience and efficiency of opening the two protective doors 200. The baffle 206 facilitates the passage of the baffle 206. The 06 baffle plate 206 blocks machining debris that splashes onto the protective door 200 during processing. The second spring damper 207 buffers the impact force generated by the machining debris, which helps to improve the service life of the protective door 200. At the same time, the baffle plate 206 improves the protective effect of the protective door 200. When it is necessary to disassemble and replace the baffle plate 206 and the second spring damper 207, turn the Torx handle screw 211 to release the limit of the polygonal guide post 208, and the polygonal guide post 208, baffle plate 206 and second spring damper 207 can be disassembled, which improves the replacement efficiency of the baffle plate 206 and the second spring damper 207.
