[0027] Embodiment 1:

[0028] The utility model provides a robot position accuracy detection device.

[0029] In one embodiment of the utility model, a robot position accuracy detection device includes a support frame 1, a base 2, an adjustment assembly and a clamping assembly. The base 2 is detachably mounted on the support frame 1. The adjustment assembly includes an adjustment block 3 and a movable seat 4. The adjustment block 3 is mounted in the base 2 for limited movement. A slope 5 is provided on the top surface of the adjustment block 3. The slope 5 is inclined along the moving direction of the adjustment block 3. A slide groove 6 for the adjustment block 3 to extend into is provided on the bottom surface of the movable seat 4. The bottom of the slide groove 6 abuts against the slope 5, and a locking member 7 is detachably mounted on the side wall of the slide groove 6. The clamping assembly is arranged on the movable seat 4, and the clamping assembly includes two clamping plates 8, which are respectively used to abut against the outer walls on both sides opposite to the detector 100.

[0030] Specifically, Figure 1 and Figure 2 As shown, in a robot position accuracy detection device of the utility model, the support frame 1 can be selected as a tripod in the prior art, and the base 2, the detector 100 and several components are supported by the tripod, so that the robot position accuracy detection can be realized, and the structural design is simple and reasonable. Furthermore, the adjustment block 3 in the adjustment component is installed in the base 2 with limited movement, and the limited movement of the adjustment block 3 can be driven by a hydraulic cylinder or a mechanism that can drive the adjustment block 3 to move linearly. When the adjustment block 3 moves, since a slope 5 is provided on the top surface of the adjustment block 3 along its moving direction, a slide groove 6 is provided on the bottom surface of the movable seat 4 for the adjustment block 3 to extend into, and the bottom of the slide groove 6 is in contact with the slope 5, so that the movable seat 4 can gradually move upward or downward under the action of the adjustment block 3, thereby realizing the detection. The lifting and lowering fine-tuning of the measuring instrument 100 is ingeniously and reasonably designed. At the same time, since a locking piece 7 is detachably installed on the side wall of the slide 6, the locking piece 7 can be selected as a screw or a handwheel with a stud in the prior art, and the locking piece 7 is detachably connected to the slide 6 by a threaded connection. By screwing the locking piece 7, the movable seat 4 is pressed against the adjusting block 3, and the movable seat 4 can move synchronously with the adjusting block 3, thereby realizing fine-tuning of the movement of the measuring instrument 100 in the horizontal plane, which not only facilitates the adjustment operation but also improves the flexibility of use.

[0031] It can be understood that when the detector 100 needs to be installed, since the clamping assembly is arranged on the movable seat 4, and the two clamping plates 8 in the clamping assembly are respectively used to abut against the opposite outer walls of the detector 100, at this time, the bottom surface of the detector 100 abuts against the top surface of the movable seat 4, and then the two clamping plates 8 are used to abut and limit the opposite outer walls of the detector 100, so as to clamp and fix the detector 100, so that the detector 100 can be firmly placed on the movable seat 4, thereby ensuring the placement stability of the detector 100, reducing the probability of the detector 100 falling and being damaged, extending the service life of the detector 100, and being simple to operate and easy to use.

[0032] In one embodiment, specifically, Figure 1 and Figure 2 As shown, a groove 9 is provided on the top surface of the movable seat 4, and the clamping assembly also includes a mounting seat 10 and a first adjusting screw 11. The mounting seat 10 is detachably mounted in the groove 9. A through groove 12 is provided on the mounting seat 10, and the first adjusting screw 11 is inserted in the through groove 12. The first adjusting screw 11 is formed with two sections of threaded segments with opposite rotation directions, and the two clamping plates 8 are respectively threadedly matched with the two sections of threaded segments through the through groove 12. When the detector 100 needs to be clamped and installed, the staff rotates the first adjusting screw 11 clockwise relative to the mounting seat 10 so that the two clamping plates 8 can be close to each other, so that the detector 100 can be firmly clamped and limited; similarly, when the detector 100 needs to be disassembled and repaired, the staff rotates the first adjusting screw 11 counterclockwise relative to the mounting seat 10 so that the two clamping plates 8 can be separated from each other, thereby making the two clamping plates 8 disengage from the abutment with the detector 100, and the staff can directly remove the detector 100 from the movable seat 4, which is simple to operate and convenient to use.

[0033] In one embodiment, if Figure 2 As shown, both ends of the first adjusting screw 11 extend out of the mounting seat 10 and are detachably connected to the first hand wheel 13, so that the staff can turn the first adjusting screw 11 to move and adjust the two clamping plates 8 without the need for other disassembly and assembly tools, such as wrenches.

[0034] In one embodiment, the two clamping plates 8 are both L-shaped clamping plates, and the two clamping plates 8 are respectively provided with flexible blocks 14 on opposite sides thereof, and the two clamping plates 8 are provided with ribs 15 on the sides thereof facing away from each other. Figure 1 and Figure 2 As shown, after the two clamps 8 clamp and limit the detector 100, since the flexible blocks 14 are respectively provided on the opposite sides of the two clamps 8, the two flexible blocks 14 are respectively in contact with the outer walls of the two sides of the detector 100, and the flexible blocks 14 can be rubber blocks in the prior art, thereby preventing the two clamps 8 from clamping the surface of the detector 100, protecting the detector 100, and making it reliable to use.

[0035] In one embodiment, both ends of the base 2 along its extension direction are bent upward to form a limit plate 16 and a mounting plate 17, the limit plate 16 is used to abut against the detector 100, and a second adjusting screw 18 is passed through the mounting plate 17 along the extension direction of the base 2, one end of the second adjusting screw 18 is threadedly connected to the adjustment block 3, and the other end of the second adjusting screw 18 extends in a direction away from the mounting plate 17 and is detachably mounted with a second hand wheel 19.

[0036] Specifically, Figure 1 and Figure 2 As shown, when the detector 100 needs to be installed, the staff can place the detector 100 on the movable seat 4 and at the same time abut the detector 100 against the limit plate 16 to perform preliminary positioning of the detector 100 and limit the detector 100 along its extension direction, and then rotate the first hand wheel 13 so that the first adjusting screw 11 drives the two clamping plates 8 to clamp and limit the outer walls of the two sides of the detector 100, thereby completing the installation and fixing of the detector 100, and improving the installation stability of the detector 100. Further, since the second adjusting screw 18 is penetrated on the mounting plate 17 along the extension direction of the base 2, and one end of the second adjusting screw 18 is threadedly connected to the adjusting block 3, and the other end of the second adjusting screw 18 is detachably mounted with a second hand wheel 19, the staff can drive the adjusting block 3 to move along the extension direction of the base 2 by rotating the second hand wheel 19, and thereby realize the lifting and lowering fine adjustment and the movement fine adjustment in the horizontal plane of the detector 100, and the structural design is simple and reasonable.

[0037] In one embodiment, the outer walls of both sides of the adjusting block 3 are provided with limiting grooves 20 for the locking member 7 to extend into, and the extending direction of the limiting grooves 20 is consistent with the inclination direction of the slope 5. It can be understood that, if Figure 1 and Figure 2 As shown, the staff can realize the synchronous movement of the movable seat 4 and the adjustment block 3 by screwing the locking member 7 so that it can extend into the limiting groove 20 and abut against the groove bottom of the limiting groove 20, thereby realizing the movement and adjustment of the detector 100 in the horizontal plane. Furthermore, the staff can reversely screw the locking member 7 so that it can disengage from the groove bottom of the limiting groove 20 without withdrawing from the limiting groove 20, thereby not only ensuring that the movable seat 4 can be lifted and lowered with respect to the base 2, but also preventing the movable seat 4 from being loosened from the adjustment block 3, thereby improving the installation stability of the movable seat 4.

[0038] In one embodiment, specifically, Figure 1 and Figure 2 As shown, a guide groove is provided on the bottom surface of the adjusting block 3 along its extending direction, and the base 2 is in sliding contact with the guide groove, thereby ensuring the smoothness of the adjusting block 3 during movement.

[0039] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
