Description

Technical Field

[0001] The utility model belongs to the technical field of numerically controlled lathes, and in particular relates to a detection device for detecting the verticality of the moving directions of a Z-axis and an X-axis of a numerically controlled lathe. Background Art

[0002] The turret assembly of the CNC lathe is installed on the turret slide at the junction of the Z-axis guide and the X-axis guide. After the CNC lathe has been used for a period of time, it is necessary to regularly check the verticality of the turret assembly in the Z-axis and X-axis movement directions. This verticality is generally tested with a marble ruler. Due to the complex structure of the CNC lathe itself and the small internal space, it is often difficult to stably fix the marble ruler when testing the verticality. In order to obtain accurate data, the lathe protective cover must be removed before the marble ruler can be fixed and the data can be tested. Removing and installing the lathe protective cover generally takes more than two hours, which is time-consuming and labor-intensive, and is not suitable for on-site rapid testing in production. Therefore, it is necessary to design a detection device that avoids the removal and installation of the protective cover and can quickly measure the lathe accuracy, that is, the verticality of the lathe Z-axis and X-axis movement directions in a small space.

The transverse support plate 2312 is arranged in the same plane as the pair of longitudinal support plates 2311. The connecting cross bar 2313 is fixedly installed on the lower surface of the pair of longitudinal support plates 2311. The central axis of the hollow sleeve 232 is arranged parallel to the connecting cross bar 2313. The hollow sleeve 232 is fixedly installed on the lower surface of the connecting cross bar 2313. The hollow sleeve 232 is sleeved on the third connecting column 2233.

[0050] A pair of fastening screws 24 are installed on the side walls of the oblique sleeve 221, the connecting sleeve 2231 and the hollow sleeve 232;

[0051] The marble square ruler 1 is installed on the square ruler support frame 231 .

[0052] In this embodiment, the fixed base 211 is fixedly installed on the guard plate side wall 3 under the protective door of the CNC lathe, the mounting column 212 and the first connecting column 213 face the inside of the CNC machine tool, the inclined sleeve 221 is sleeved on the first connecting column 213, the direction of the connecting rod 222 is adjusted, and after the vertical plane where the connecting rod 222 is located is parallel to the vertical plane where the X-axis guide rail is located, the pair of fastening screws 24 on the inclined sleeve 221 are tightened to keep the direction of the connecting rod 222 fixed, and then the third connecting column 2233 is adjusted to make the vertical plane where the third connecting column 2233 is located parallel to the vertical plane where the Z-axis guide rail is located, the pair of fastening screws 24 on the connecting shaft sleeve 2231 are tightened to keep the direction of the third connecting column 2233 fixed, and then the hollow sleeve 232 is sleeved on the third connecting column 2233, and the angle of the square ruler support frame 231 is adjusted so that the plane where it is located is parallel to the vertical plane where the X-axis guide rail is located. After the planes where the axis guide rails and the Z-axis guide rails are parallel, tighten a pair of fastening screws 24 on the hollow sleeve 232 to keep the square ruler support frame 231 fixed, place the marble square ruler 1 on the square ruler support frame 231, and align the side wall of the marble square ruler 1 with the outer edge of the square ruler support frame 231, then adsorb the dial indicator or micrometer on the turret assembly, so that the contacts of the dial indicator or micrometer contact the X-axis (longitudinal) side wall or the Z-axis (transverse) side wall of the marble square ruler 1, and perform verticality detection. The fixed base assembly 21 is easy to install. Because the overall CNC lathe is not a regular cubic structure, the connection method of the various components of the connecting assembly 22 can ensure the six degrees of freedom of the square ruler frame assembly 23. The position of the square ruler frame assembly 23 can be quickly and accurately adjusted inside the small space of the CNC machine tool, so that it can be extended to the vicinity of the component to be measured, that is, the turret assembly.

[0053] As a preferred solution of this embodiment, the fixed base 211 in this embodiment includes a pair of U-shaped mounting frames connected to each other, and the U-shaped mounting frames include a pair of vertical rods 2111. The top ends of the pair of vertical rods 2111 are fixedly connected by a longitudinal cross bar 2112, and the pair of longitudinal cross bars 2112 are fixedly connected by a first cross bar 2113. A second cross bar 2114 is fixedly connected between the bottom ends of the vertical rods 2111 of the pair of U-shaped mounting frames arranged on the same side. The structure of the U-shaped mounting frame enables the fixed base 211 to be clamped on the guard plate side wall 3 under the protective door of the CNC lathe, and a plurality of vertical rods 2111 of each U-shaped mounting frame are provided in the longitudinal direction. There are symmetrically arranged through holes, each of which is welded with a nut 2115, and a fastening screw 2116 is installed in the nut 2115. The tightness of the fastening screw 2116 can be adjusted in both directions according to the thickness of the side wall 3 of the guard plate, so that the fixed base 211 is suitable for various types of CNC lathes and can be stably installed. The middle part of one of the second cross bars 2114 is fixedly connected to one end of a longitudinally arranged support rod 2117, and the bottom end of the mounting column 212 is fixedly installed on the other end of the support rod 2117. The mounting column 212 is arranged parallel to the fixed base 211, and the fixed base assembly 21 is a stable base for the entire device, which improves the stability of the overall device and the accuracy of measurement.

[0054] As a preferred solution of this embodiment, the angle between the central axis of the inclined sleeve 221 and the central axis of the connecting rod 222 in this embodiment is 30°~60°. This angle setting makes the device suitable for CNC lathes in small spaces. Connecting components 22 with different angles can be selected according to CNC lathes of different space sizes, ultimately ensuring that the square frame assembly 23 is located near the turret assembly.

[0055] As a preferred solution of this embodiment, in this embodiment, the connecting cross bar 2313 is horizontally arranged in the middle of a pair of longitudinal support plates 2311, and the vertical plane where the connecting rod 222 is located is located in the middle of the connecting cross bar 2313. The hollow sleeve 232 is adjusted to the position of the third connecting column 2233 so that the supporting force of the connecting component 22 on the square ruler frame component 23 acts on the center of the square ruler frame component 23, so that the center of gravity of the overall device is stable. The cross section of the connecting cross bar 2313 is an L-shaped structure and the L-shaped opening is vertically downward. The outer wall of the hollow sleeve 232 is welded and fixed to the two inner walls of the connecting cross bar 2313. The L-shaped structure can disperse the pressure of the square ruler support frame 231 on which the marble square ruler 1 is installed on the hollow sleeve 232, thereby avoiding damage to the welding part of the hollow sleeve 232 and the connecting cross bar 2313 due to excessive force.

[0056] As a preferred solution of this embodiment, in this embodiment, the lateral outer sides of a pair of longitudinal support plates 2311 and the longitudinal outer sides of the lateral support plates 2312 are integrally provided with vertical anti-slip edges 2314. The square ruler support frame 231 is a U-shaped structure as a whole, and the U-shaped opening faces the Z-axis guide rail. The above structure is convenient for the installation of the marble square ruler 1 so that its side wall is aligned with the outer edge of the square ruler support frame 231, and can also prevent the marble square ruler 1 from falling due to improper operation, causing damage to the staff or the machine. The height of the vertical anti-slip edge 2314 is not more than 1 / 2 of the thickness of the marble square ruler 1, which can ensure that during the verticality detection process, the contacts of the dial indicator or micrometer are in contact with the side wall of the marble square ruler 1, and the vertical anti-slip edge 2314 does not directly contact the side wall of the marble square ruler 1, leaving room for fine-tuning the position of the marble square ruler 1 in the later stage.

[0057] As a preferred solution of the present embodiment, a pair of laterally symmetrically arranged vertical baffles 2315 are welded on the vertical anti-slip edge 2314 of the transverse support plate 2312 in the present embodiment, and longitudinally arranged fine-tuning screws 2316 are installed on the vertical baffles 2315. The ends of the fine-tuning screws 2316 are in contact with the side walls of the marble square ruler 1. When the lateral side walls of the marble square ruler 1 are not parallel to the Z-axis guide rail, the parallelism of the marble square ruler 1 with respect to the Z-axis guide rail can be fine-tuned by adjusting the tightness of the fine-tuning screws 2316 with respect to the side walls of the marble square ruler 1 according to actual conditions.

[0058] Furthermore, the fine-tuning screw 2316 is arranged at the same height as the middle cross section of the marble square ruler 1 , so that the fine-tuning screw 2316 can effectively apply force to the side wall of the marble square ruler 1 .

[0059] As a preferred solution of this embodiment, the distance between a pair of vertical rods 2111 of the U-shaped mounting frame in this embodiment is 60 mm, the length of the vertical rod 2111 is 600 mm, the length of the first cross bar 2113 and the second cross bar 2114 is 400 mm, the length of the mounting column 212 is 90 mm, and the length of the first connecting column 213 is 30 mm. The above data makes the fixed base assembly 21 suitable for small and medium-sized CNC machine tools.

[0060] The specific implementation of this device is:

[0061] 1. Preparation: Select the appropriate size of the device according to the type of CNC machine tool and the model of marble square ruler. Before installation, check whether all parts are complete, whether there are obvious defects or deformations on the surface of the device, and whether the connection parts are stuck.

[0062] 2. Installation and adjustment work: After checking that everything is correct, carry out installation and adjustment work. Install the device according to the stopped state of the CNC lathe, adjust each part to the appropriate angle and position and then fix it. Specifically, make the installation column 212 and the first connecting column 213 face the CNC machine tool, clamp the fixed base 211 on the guard plate side wall 3 under the protective door of the CNC lathe from above, and tighten the fastening screw 2116 from both sides. The top of the fastening screw 2116 is against the guard plate side wall 3, and the fixed base assembly 21 is fixed and installed, and then the connecting assembly 22 is set on the first connecting column 213, and the height of the inclined sleeve 221 on the first connecting column 213 and the direction of the connecting rod 222 are adjusted. After the vertical plane where the connecting rod 222 is located is parallel to the vertical plane where the X-axis guide rail is located, and the height of the direction transposition joint 223 is appropriate, tighten the pair of fastening screws 24 on the inclined sleeve 221 to keep the direction and height of the connecting rod 222 fixed, and then adjust the third connecting column 2 233, make the vertical plane where the third connecting column 2233 is located parallel to the vertical plane where the Z-axis guide rail is located, tighten the pair of fastening screws 24 on the connecting sleeve 2231 to keep the third connecting column 2233 fixed, make the U-shaped opening of the square ruler support frame 231 face the direction of the Z-circular guide rail, put the hollow sleeve 232 on the third connecting column 2233, adjust the position of the hollow sleeve 232 relative to the first connecting column 2233, and after the vertical plane where the connecting rod 222 is located is located in the middle of the connecting cross bar 2313, adjust the angle of the square ruler support frame 231 so that its plane is parallel to the plane where the X-axis guide rail and the Z-axis guide rail are located, the longitudinal support plate 2311 is parallel to the X-axis guide rail, and the transverse support plate 2312 is parallel to the Z-axis guide rail, tighten the pair of fastening screws 24 on the hollow sleeve 232 to keep the square ruler support frame 231 fixed, and then install the marble square ruler 1 on the square ruler support frame 231. After installation, check whether the connections of each component are secure.

[0063] 3. Fine-tuning detection work: After the device is fixed and installed, enter the fine-tuning detection work, install the dial indicator or micrometer on the turret assembly, make the contact of the dial indicator or micrometer vertically contact with the upper surface of the marble square ruler 1, start the turret base, and move it along the X-axis guide rail or the Z-axis guide rail. The contact of the dial indicator or micrometer moves on the upper surface of the marble square ruler 1. Use the dial indicator or micrometer to judge whether the upper surface of the marble square ruler 1 is parallel to the plane where the X-axis guide rail and the Z-axis guide rail are located. If the swing value of the dial indicator or micrometer needle is not within the allowable value range, the upper surface of the marble square ruler 1 is parallel to the X-axis guide rail and the Z-axis guide rail. The planes where the X-axis guide rails and the Z-axis guide rails are located are not parallel, and the axial angle of the square ruler support frame 231 relative to the third connecting column 2233 is finely adjusted until the needle of the dial indicator or micrometer does not swing or the swing value is within the allowable value range. At this time, the upper surface of the marble square ruler 1 is parallel to the planes where the X-axis guide rails and the Z-axis guide rails are located. Tighten the fastening screws 24 to fix the state that the upper surface of the marble square ruler 1 is parallel to the planes where the X-axis guide rails and the Z-axis guide rails are located. Next, the contact of the dial indicator or micrometer is vertically contacted with the side wall of the marble square ruler 1 facing the Z-axis guide rail, and the turret base is started to move along the Z-axis guide rail to start the Z-axis of the CNC lathe. The parallelism of the moving direction is measured. If the swing value of the dial indicator or micrometer needle is not within the allowable value range, the side wall of the marble square ruler 1 facing the Z-axis guide rail is not parallel to the Z-axis guide rail. It is necessary to adjust the tightness of one of the fine-tuning screws 2316 relative to the side wall of the marble square ruler 1 for fine-tuning. For example, the left end of the side wall of the marble square ruler 1 facing the Z-axis guide rail is closer to the Z-axis guide rail, and the fine-tuning screw 2316 corresponding to the right side needs to be fine-tuned forward until the pointer of the dial indicator or micrometer no longer swings. Then, the moving direction of the CNC lathe on the Z-axis guide rail is parallel to the lateral side wall of the marble square ruler 1. The next step is to adjust the dial indicator or micrometer. The contacts of the meter are in vertical contact with the side wall of the marble square 1 facing the X-axis guide rail, and the turret base is started to move it along the X-axis guide rail. The verticality of the movement directions of the Z axis and the X axis of the CNC lathe is detected by the dial indicator or micrometer. If the needle of the dial indicator or micrometer does not swing or the swing value is within the allowable range, the movement directions of the Z axis and the X axis of the CNC lathe are perpendicular, and the accuracy of the CNC machine tool meets the factory requirements and does not need to be repaired. If the swing value of the needle of the dial indicator or micrometer is greater than the allowable value, the movement directions of the Z axis and the X axis of the CNC lathe are not perpendicular, and the CNC lathe needs to be repaired and adjusted to the allowable range.
