Description

Technical Field

[0001] This application relates to the field of CNC machine tool technology, specifically to a maintenance and testing device for CNC machine tools. Background Technology

[0002] A CNC machine tool is an automated machine tool equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, and thus enable the machine tool to move and process parts. CNC machine tools integrate mechanical, automation, computer, measurement, and microelectronic technologies, and are characterized by high precision, high efficiency, and high flexibility.

[0003] For example, Chinese utility model patent publication number "CN212918675U" discloses a maintenance and testing device for CNC machine tools. This utility model uses a handwheel to rotate forward and backward, driving a lead screw to rotate in both directions. The left and right ends of the lead screw's outer surface are fixedly connected with threads in opposite directions. The inner side of the slider has a threaded groove that matches the threads on the lead screw's outer surface. A limiting rod and a limiting groove restrict the slider's circumferential motion following the lead screw, causing the two sliders to drive two insert rods to move towards opposite or opposite sides. When the two insert rods move towards opposite sides, they move out of the sliding holes in the fixed rod. Then, the top cover moves upward, causing the limiting rod to disengage from the limiting groove, allowing maintenance of the internal parts of the maintenance and testing device. The rod moves to the opposite side, at which point the insertion rod is located inside the sliding hole, thus limiting and fixing the top cover. This device converts the rotational force of the lead screw into the left and right movement force of the insertion rod, allowing the insertion rod to move out or in through the sliding hole on the fixed rod, thereby enabling the disassembly of the top cover and facilitating maintenance of the internal components of the maintenance and testing device. No bolts are needed to fix the top cover; assembly and disassembly are simple and suitable for various situations. By incorporating a heat sink and heat dissipation fins, the heat sink and heat dissipation fins cool the internal electronic components of the maintenance and testing device. Simultaneously, a fan quickly exhausts the heat from inside the maintenance and testing device through the heat dissipation vents. Furthermore, the dust filter and dust cover ensure that dust does not enter the interior of the maintenance and testing device.

[0004] The aforementioned patent facilitates the maintenance of the internal structure of the inspection and testing device. However, the method for disassembling the dustproof net in the device is rather cumbersome. During the disassembly process, it is necessary to first turn the handwheel to move the insertion rod and then disassemble the top cover. The operation involves many steps, which consumes time and manpower. This affects the maintenance efficiency of the inspection and testing device to a certain extent, increases the downtime of the equipment, and is not conducive to production continuity.

[0032] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0033] Reference Figure 1 and Figure 2This application provides a maintenance and testing device for CNC machine tools, including a testing device body 1. A connecting support mechanism 2 for supporting the device is provided below the testing device body 1. Ventilation mechanisms 3 for ventilating and cooling the inside of the device are provided on both sides of the testing device body 1. The ventilation mechanism 3 includes a connecting plate 304 and a limiting block 307. The connecting plate 304 is fixedly installed on both sides of the testing device body 1, and the limiting block 307 is slidably connected to the inner wall surface of the connecting plate 304. By activating the connecting support mechanism 2, the hydraulic rod 204 can be activated to drive the support plate 205 to descend. The support plate 205 lifts the device to ensure the stability of the device during use. After unscrewing the bolt on one side of the positioning plate 203, the control panel 202 can be pulled upward to remove the control panel 202 and the connecting ring 201 from the device for maintenance. The ventilation mechanism 3 can draw in external air by starting the fan 309, allowing it to circulate inside the device and then be discharged from the other side to remove the heat generated during device use. As air enters and exits the device, the filter plate 303 filters the air to prevent dust from entering the device. When dust accumulates on the surface of the filter plate 303, the sliding rod 306 is pulled to move the limiting block 307 while squeezing the spring 308 to retract it. After the limiting block 307 is no longer in contact with the connecting plate 304, the connecting plate 304, the filter plate 303, and the sliding plate 302 can be pulled upwards to remove the connecting plate 304, the filter plate 303, and the sliding plate 302 from the inside of the connecting frame 301 for cleaning or replacement of the filter plate 303.

[0034] Reference Figure 3 , Figure 4 and Figure 5 In one aspect of this embodiment, mounting frames 301 are fixedly installed on both sides of the test device body 1, a sliding plate 302 is slidably connected to the inner wall surface of the mounting frame 301, and a filter plate 303 is fixedly installed on one side of the sliding plate 302.

[0035] The connecting plate 304 is fixedly installed on the upper surface of the filter plate 303. The two sides of the test device body 1 are fixedly installed with fixing blocks 305. The fixing block 305 is slidably connected to one side of the sliding rod 306. The limiting block 307 is fixedly installed at one end of the sliding rod 306.

[0036] A spring 308 is fixedly installed on one side of the limiting block 307, and the other end of the spring 308 is fixedly connected to one side of the inner wall of the fixing block 305. The spring 308 is movably wound around the surface of the slide rod 306. Fans 309 are fixedly installed on both sides of the inner wall of the test device body 1. By starting the fan 309, external air is drawn in and circulated inside the device before being discharged from the other side of the device to remove the heat generated during the use of the device. When air enters and exits the device, the filter plate 303 filters the air to prevent dust from entering the device. When dust accumulates on the surface of the filter plate 303, the slide rod 306 is pulled to move the limiting block 307 and squeeze the spring 308 to retract it. After the limiting block 307 is no longer in contact with the connecting plate 304, the connecting plate 304, the filter plate 303 and the slide plate 302 can be removed from the inside of the connecting frame 301 to clean or replace the filter plate 303.

[0037] Reference Figure 1 and Figure 2 In one aspect of this embodiment, a connecting ring 201 is slidably connected to the inner wall surface of the test device body 1, a control panel 202 is fixedly installed on the upper surface of the connecting ring 201, and positioning plates 203 are fixedly installed on both sides of the control panel 202.

[0038] A hydraulic rod 204 is fixedly installed on the lower surface of the test device body 1. A support plate 205 is fixedly installed on one end of the hydraulic rod 204. By activating the hydraulic rod 204, the support plate 205 is lowered. The support plate 205 lifts the device to ensure the stability of the device during use. After unscrewing the bolts on one side of the positioning plate 203, the control panel 202 can be pulled upward to remove the control panel 202 and the connecting ring 201 from the device for easy inspection of the device's internal parts.

[0039] All electrical devices in this plan are powered by an external power source.

[0040] Working Principle: When using this device, first move it to a suitable position, then activate the hydraulic rod 204 to lower the support plate 205. The support plate 205 then lifts the device to ensure its stability during use. During CNC machine tool maintenance and testing, activate the fan 309 to draw in external air, which circulates within the device and exits from the other side to remove heat generated during operation. The filter plate 303 filters the air as it enters and exits, preventing dust from entering. When internal maintenance is required, unscrew the bolts on one side of the positioning plate 203 and pull upwards to remove the control panel 202 and connecting ring 201 from the device for easy access. When dust accumulates on the surface of filter plate 303, pull slide rod 306 to move limit block 307 while squeezing spring 308 to retract it. After limit block 307 is no longer in contact with connecting plate 304, pull connecting plate 304 upward to remove connecting plate 304, filter plate 303 and slide plate 302 from inside connecting frame 301 for cleaning or replacement of filter plate 303.
