Description

Technical Field

[0001] The utility model relates to the field of slot distance detection devices, in particular to an inverted slot distance detection device. Background Art

[0002] With the continuous advancement of science and technology, manufacturing technology is constantly being updated. In mechanical processing, due to the different structural requirements of parts, special equipment is needed to detect the slot distance.

[0003] Chinese patent application number CN201520452702.3 provides a handheld slot distance detection device. This solution calibrates the dial indicator to zero. Then, through the cooperation of the support surface, spring, and measuring head, the detection device can be extended into the inner hole slot of the workpiece for measurement. Finally, the difference is calculated to accurately obtain the dimension from the side surface of the inner hole slot to the outer end surface. This solves the problem that existing detection tools cannot measure or cannot perform accurate measurements due to their structure.

[0004] The existing slot pitch detection device has certain disadvantages when used. First, since the slot pitch detection device detects different specifications and sizes of slot pitches, when encountering a slot pitch that is difficult to fix, the slot pitch detection device is prone to falling off and loosening during use, affecting the accuracy of the detection. For this reason, we propose an inverted slot pitch detection device. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the purpose of the utility model is to provide an inverted slot spacing detection device. By setting a movable rod and a positioning ring, multiple positioning rings enter the inverted slot as they are adjusted, and the movable rod moves in position, which can drive the positioning ring at the outer end to adjust the position, so that the positioning ring can conveniently adjust the position of the slot spacing and lock it in place, making the detection device more stable when detecting the inverted slot spacing, and will not fall off or deviate, thereby improving the detection effect of the inverted slot spacing detection device.

[0006] The above technical objectives of the present invention are achieved through the following technical solutions:

[0007] An undercut type slot distance detection device comprises a connecting mechanism, a positioning mechanism is installed at the bottom end of the connecting mechanism, and a locking mechanism is slidably mounted on the inner end of the connecting mechanism;

[0008] The locking mechanism includes a movable rod, which is evenly distributed. The outer end of the movable rod is sleeved with an adjusting piece. The front side of the adjusting piece is movably connected with a guide ring. The guide ring is located at the outer end of the movable rod. The front end of the movable rod is installed with a positioning ring.

[0009] By installing the movable rod and the positioning ring, the detection effect of the undercut type slot distance detection device is improved.

[0010] Furthermore, a movable groove is provided on the outside of the movable rod, and an adjustment groove is provided at the rear end of the movable groove.

[0011] By installing the movable slot, the adjustable position of the movable rod can be made more stable and will not deviate or fall off.

[0012] Furthermore, the outer side of the positioning ring is movably connected to a measuring piece, and the inner end of the measuring piece is slidably connected to a connecting piece.

[0013] By installing the measuring piece, the device can be used for slot distance detection more conveniently.

[0014] Furthermore, an elastic member is installed at the rear end of the connecting member, a sliding block is installed at the outer end of the connecting member, and a sliding groove is provided at the inner end of the measuring member.

[0015] By installing the sliding block, the connection piece can be adjusted to different slot distances with the measuring piece, making detection more convenient and stable.

[0016] Furthermore, the connecting mechanism includes a connecting rod, a reinforcement rod is installed at the outer end of the connecting rod, an assembly groove is opened at the inner end of the reinforcement rod, and a threaded rod is threadedly connected to the inner end of the assembly groove.

[0017] By installing the threaded rod, the use effect of the detection device is further improved.

[0018] Furthermore, an adjustment frame is installed at the bottom end of the connecting rod, and a sliding rod is installed at the inner end of the adjustment frame.

[0019] By installing the adjustment frame, the adjustment frame can facilitate the connection between the positioning mechanism and the connecting mechanism.

[0020] Furthermore, the outer end of the slide rod is sleeved with evenly distributed reset components, the inner end of the reset component is slidably connected with symmetrically distributed sliders, and the bottom end of the slider is installed with a positioning plate.

[0021] The installation of the reset assembly and the positioning plate improves the convenience of operating the device.

[0022] Furthermore, anti-drop pads are installed on the outer ends of the positioning plates, and guide grooves are provided on the inner ends of the adjustment frames.

[0023] By installing the anti-slip pad, the anti-slip pad can increase the positioning effect of the positioning plate.

[0024] In summary, the present invention has the following beneficial effects:

[0025] 1. By setting up a movable rod and a positioning ring, multiple positioning rings are adjusted to enter the undercut groove. The movable rod moves, which can drive the outer positioning ring to adjust its position. This allows the positioning ring to be conveniently adjusted to the groove pitch and locked in place. This makes the detection device more stable when detecting the undercut groove pitch, and will not fall off or deviate, thereby improving the detection effect of the undercut groove pitch detection device.

[0026] 2. By setting a sliding block, the sliding block can be adjusted along with the movement of the connector. The sliding block slides at the inner end of the slide groove, which can make the connector length adjustment more stable and will not deviate. It also makes it more convenient and stable to adjust the connector to different slot distances with the measuring piece.

[0027] 3. By setting up a reset component and a positioning plate, when the device is used, a pair of positioning plates are positioned at both ends of a mounting platform, and the reset component can drive the positioning plates to adjust their positions, so that the positioning plates can be adjusted according to the installation position, which makes it easier for the slot distance detection device to be positioned during detection, thereby improving the convenience of the device's operation.
