Description

Technical Field

[0001] This utility model relates to the technical field of testing equipment, and in particular to a dental gauge testing machine. Background Technology

[0002] Go and no-go gauges are commonly used hole diameter measuring tools. The go gauge indicates the lower limit of the permissible deviation of the hole diameter. If a workpiece cannot pass through the go gauge, it indicates that its hole diameter is too small and does not meet the standard. The no-go gauge indicates the upper limit of the permissible deviation of the hole diameter. If a workpiece can pass through the no-go gauge, it indicates that its hole diameter is too large, and it is also unqualified. Therefore, only when a workpiece can pass through the go gauge but not the no-go gauge can it be judged as qualified. Conventional go and no-go gauges are inspected manually. To improve efficiency, it is necessary to design a mechanized method to inspect the hole diameter of the workpiece. Utility Model Content

[0003] This invention provides a tooth gauge inspection machine with a simple structure, which reduces manual intervention in inspecting whether the hole diameter of the workpiece is qualified, thereby improving efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a thread gauge inspection machine, comprising a feeding assembly, a go gauge inspection assembly, a no-go gauge inspection assembly, a transfer assembly, and an unloading assembly. The transfer assembly includes a conveying track, a transfer plate, and a driving mechanism for moving the transfer plate. The conveying track is provided with feeding positions, go gauge inspection positions, and no-go gauge inspection positions that are respectively connected to the feeding assembly, the go gauge inspection assembly, and the no-go gauge inspection assembly along a straight line. The conveying track is provided with a feeding notch at the feeding position. The conveying track is provided with clearance holes at both the go gauge inspection position and the no-go gauge inspection position. The transfer plate is provided with a plurality of locking blocks adapted to the workpiece to be inspected.

[0005] In the above scheme, the workpiece to be inspected is fed onto the conveyor track at the feeding position by the feeding assembly. The workpiece on the conveyor track sequentially passes through the go gauge detection position and the no-go gauge detection position, finally falling off the conveyor track into the unloading assembly for unloading. The workpiece undergoes go gauge inspection at the go gauge detection position and no-go gauge inspection at the no-go gauge detection position, thus reducing manual intervention and eliminating the need for manual go and no-go gauge inspection, thereby improving efficiency. The movement of the workpiece on the conveyor track is achieved through a transfer assembly.

[0006] In one embodiment, the feeding assembly includes a hopper, a vibratory feeder located below the outlet of the hopper, and a first lifting module located at the end of the conveying channel of the vibratory feeder and connected to the conveying channel. The first lifting module includes a first lifting cylinder and a first lifting block disposed on the output end of the first lifting cylinder and cooperating with the workpiece to be tested. The first lifting block can move up and down at the feeding notch. When the workpiece to be tested is lifted to the upper limit position by the first lifting block, the upper part of the first lifting block is aligned with the top of the conveying track.

[0007] In the above scheme, the vibratory feeder can neatly and continuously supply the workpiece to be inspected to the first lifting block, which lifts it to a position aligned with the top of the conveying track. Subsequently, the transfer plate moves to drive the locking block, thus enabling the workpiece to be inspected to move on the conveying track and move to the gauge inspection position.

[0008] In one embodiment, the go gauge detection assembly includes a first lifting seat, a first rotary motor disposed on the first lifting seat, and a first threaded plug gauge disposed on the output end of the first rotary motor, wherein the first threaded plug gauge is located directly above the clearance hole at the go gauge detection position.

The first slide rail is parallel to the conveying track. The second mounting plate is provided with a second slide rail that is adapted to the transfer plate. The second slide rail is perpendicular to the first slide rail.

[0014] In the above scheme, the drive mechanism allows the transfer plate to move forward, backward, left, and right, enabling the transfer plate to use multiple locking blocks to laterally move each workpiece to be inspected on the conveyor track. For example, one locking block first locks a workpiece to be inspected, and moving the transfer plate to the right drives the workpiece to be inspected to move to the right and enter another station. Then, the transfer plate moves forward, causing the locking block to disengage from the workpiece. After that, the transfer plate moves to the left and then backward to reset.

[0015] In one embodiment, the conveying track has defective product unloading positions on one side of the go gauge detection position and the stop gauge detection position. The conveying track is disconnected at the defective product unloading position to form a unloading gap. A second lifting module is provided below the unloading gap. The second lifting module includes a second lifting cylinder and a second lifting block disposed on the output end of the second lifting cylinder and cooperating with the workpiece to be inspected.
