Description

Technical Field

[0001] The utility model relates to the technical field of angle detection, in particular to a numerical control tool rest guide angle detector. Background Technique

[0002] The emergence of the inclined bed numerical control lathe is to solve the problems of the traditional numerical control lathe in terms of machining accuracy, machine rigidity and chip removal efficiency. The common inclination angles of the existing inclined bed numerical control lathes are 30 degrees and 45 degrees. Due to different angles, the focuses are also different. For example, when the bed is inclined at 30 degrees, the machine tool has a low center of gravity and high stability, which is beneficial to improving machining accuracy. When the bed inclination is 45 degrees, it is more conducive to chip removal, thereby reducing the influence of slag on the machined parts.

[0003] With the progress of the times, customers have more and more requirements for lathes. According to different customer situations, the design of the inclination angle of some lathes can be changed. For example, the inclination angle of the lathe bed is set to 60 degrees to machine a special-shaped part of the customer from a special angle. Such unconventional angles are gradually increasing, resulting in many difficulties for factories during assembly or for purchasers during maintenance. On the one hand, there is no suitable tool to measure the inclination angle of the bed, and on the other hand, during maintenance, the turret on the small carriage greatly limits the use of tools. Content of the Utility Model

[0004] In view of the above technical problems, the utility model proposes the following technical solutions:

[0005] A numerical control tool rest guide angle detector includes a bed body. A guide rail seat is fixedly installed on the bed body. Multiple guide rails are arranged in parallel on the guide rail seat. A large carriage is slidably installed on the guide rails on the guide rail seat. The surface of the large carriage away from the guide rail seat is an inclined surface. A guide rail frame is fixedly installed on the inclined surface of the guide rail seat. A small carriage is slidably installed on the guide rail frame. A main support is arranged on the guide rail seat. The main support is in close contact with the guide rail surface of the guide rail seat. The main support is composed of a horizontal plate and a column. A movable block is slidably installed on the column of the main support. A side angle plate is fixedly installed on the movable block. The side angle plate is fan-shaped. A scale is arranged at the arc end of the side angle plate. The fan angle of the main support is 160 degrees to 180 degrees. A central axis is also arranged at the center of the fan surface of the side angle plate.

[0006] Further, a central axis is rotatably installed on the movable block. One end of the central axis is rotatably connected to the side angle plate. An axial center roller is rotatably installed at the other end of the central axis. An angle pointer is fixedly installed on the central axis near the side angle plate. A pointing arrow is arranged on the angle pointer near the side where the side angle plate is provided with scales. The pointing arrow on the angle pointer cooperates with the scales on the side angle plate to help the user confirm the angle.

[0007] Further, a swing rod is fixedly installed on the central axis. An intermediate roller is rotatably installed on the swing rod. An adjusting screw rod is also rotatably installed on the swing rod. An adjusting handle is fixedly installed at the end of the adjusting screw rod far from the central axis.

When using this device, first place the main bracket 201 on the guide rail of the guide rail base 102, and then fix the main bracket 201 on the guide rail of the guide rail base 102 through the cross plate of the main bracket 201 in cooperation with the clamping block 211, and rotate the clamping handle 213 to make the clamping block 211 perform the work of clamping or releasing.

[0018] As Figures 1 to 5As shown, a movable block 214 is slidably mounted on the column of the main bracket 201. A side angle plate 202 is fixedly mounted on the movable block 214. The side angle plate 202 is fan-shaped. A scale is provided at the arc surface end of the side angle plate 202. The fan surface angle of the main bracket 201 is from 160 degrees to 180 degrees. A central axis is also provided at the center of the fan surface of the side angle plate 202. A central axis 215 is rotatably mounted on the movable block 214. One end of the central axis 215 is rotatably connected to the side angle plate 202. The other end of the central axis 215 is rotatably mounted with a central axis roller 204. An angle pointer 203 is fixedly mounted on the central axis 215 near the side angle plate 202. A pointing arrow is provided on the side of the angle pointer 203 near the scale on the side angle plate 202. The pointing arrow on the angle pointer 203 cooperates with the scale on the side angle plate 202 to help the user confirm the angle. A swing rod 206 is also fixedly mounted on the central axis 215. An intermediate roller 205 is rotatably mounted on the swing rod 206. An adjusting screw rod 209 is also rotatably mounted on the swing rod 206. An adjusting handle 210 is fixedly mounted at the end of the adjusting screw rod 209 away from the central axis 215. An adjusting slider 208 is slidably mounted on the swing rod 206. A measuring roller 207 is rotatably mounted on the adjusting slider 208. The measuring roller 207, the intermediate roller 205, and the central axis roller 204 have the same diameter. The central axis roller 204, the intermediate roller 205, and the measuring roller 207 can be in contact with the same plane of the guide rail frame 105 at the same time. By rotating the guide rail frame 105, the adjusting slider 208 and the measuring roller 207 can slide on the swing rod 206, so that the measuring roller 207 can avoid contacting the guide rail frame 105 with the small support plate 103.

[0019] Working principle: When this device is in use, it is used when installing the guide rail frame 105 and the small support plate 103. After installing the large support plate 104 on the guide rail of the guide rail seat 102, first confirm that the large support plate 104 is installed well, and then install the guide rail frame 105 on the large support plate 104. At this time, the cross plate of the main bracket 201 can be placed on the guide rail on the guide rail seat 102. Then, by rotating the clamping handle 213, the clamping screw rod 212 can drive the clamping block 211 to move, so that the clamping block 211 is in precise contact with the side surface of the guide rail on the guide rail seat 102, and thus the installation of the main bracket 201 is completed. It should be noted here that the cross plate of the main bracket 201 needs to be in close contact with the guide rail on the guide rail seat 102.

[0020] After manually pulling the movable block 214 and manually rotating the swing rod 206, the measuring roller 207, the intermediate roller 205 and the shaft center roller 204 on the swing rod 206 are brought into contact with the guide rail frame 105, so that the inclination angle of the guide rail frame 105 is confirmed through the three points of the three measuring rollers 207, the intermediate roller 205 and the shaft center roller 204. During the rotation of the swing rod 206, the swing rod 206 will drive the angle pointer 203 to rotate together through the central shaft 215. Furthermore, the angle pointer 203 passes through the scale on the auxiliary side angle plate 202 of the pointer arrow to display the inclination angle of the guide rail frame 105, which is convenient for the user to confirm the angle and the state of the guide rail frame 105 when installing the guide rail frame 105.

[0021] In addition, this device can also be used for maintenance detection of the device in use. The usage method is the same. First, fix the cross plate on the main bracket 201 on the guide rail of the guide rail seat 102. Then rotate the adjustment handle 210, so that the adjustment handle 210 drives the position of the measuring roller 207 through the adjustment screw rod 209, and then adjust the distance between the measuring roller 207 and the intermediate roller 205 to prevent the measuring roller 207 from contacting the small support plate 103. In this way, the turret on the small support plate 103 can be opened, and then the inclination angle of the guide rail frame 105 can be detected.

[0022] The above is only the preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
