Description

Technical Field

[0001] The utility model relates to the technical field of measuring devices, in particular to a device for checking the position and size of a hole. Background Art

[0002] Many existing workpieces often need to be punched during processing. After drilling, the hole position needs to be measured to ensure the accuracy of the hole position and thus ensure the quality of the workpiece. In this process, a hole position and dimension inspection device is needed. The hole position and dimension inspection device consists of a tooling plate and several mandrels. The mandrel is inserted into the socket of the workpiece. If it can be inserted, it is a qualified workpiece. If it cannot be inserted, the workpiece is unqualified.

[0003] When manufacturing a hole position and dimension inspection device, in order to ensure the quality of the workpiece as much as possible, the mandrel is usually set to fit the opening as closely as possible. This results in the mandrel being difficult to remove from the hole after being inserted into the opening, which is inconvenient for normal use of the hole position and dimension inspection device. Utility Model Content

[0006] The effect achieved by the above components is: by setting a threaded rod and rotating the threaded rod, the threaded rod will extend and retract on the inner wall of the screw hole plate, the threaded rod will drive the tooling plate to move in the vertical direction, the tooling plate will drive the round hole block to slide synchronously on the outer surface of the round rod, and at the same time the tooling plate will drive the first mandrel and the second mandrel to separate from the opening of the workpiece, thereby facilitating the separation of the first mandrel and the second mandrel from the opening of the workpiece, and facilitating the normal use of the hole position and size inspection device.

[0007] Preferably, one end of the threaded rod is fixedly connected to a bearing, and the outer surface of the bearing is fixedly connected to the inner wall of the tooling plate.

[0009] Preferably, the other end of the threaded rod is fixedly connected to an operating block, and a protrusion is provided on the outer surface of the operating block.

[0010] The effect achieved by the above components is: by setting the operating block, rotating the operating block can drive the threaded rod to rotate, and at the same time, the outer surface of the operating block is provided with a protrusion, which can effectively increase the friction force of the outer surface of the operating block, and has an anti-slip effect when rotating the operating block, thereby facilitating the rotation of the threaded rod through the operating block.

[0011] Preferably, one end of the two round rods is fixedly connected to the same auxiliary plate, and the outer surface of the threaded rod is inserted into the inner wall of the auxiliary plate.

[0012] The effect achieved by the above components is that by setting the auxiliary plate, the top ends of the two round rods can be blocked, which is helpful to prevent the problem of the round hole block being separated from one end of the round rod due to misoperation.

[0013] Preferably, a protective plate is fixedly connected to the bottom of the auxiliary plate, the protective plate is made of rubber, and the outer surface of the threaded rod is inserted into the inner wall of the protective plate.

[0014] The effect achieved by the above components is: by setting a protective plate made of rubber material, the auxiliary plate and the tooling plate can be blocked, which is helpful to prevent the problem of excessive adjustment causing direct collision between the auxiliary plate and the tooling plate, resulting in damage to both.

[0015] Preferably, the positioning device comprises a mounting plate, the mounting plate is arranged on the top of the supporting block, and suction cups are symmetrically fixedly connected to both sides of the bottom of the mounting plate.

[0016] The effect achieved by the above components is: by setting a mounting plate with a suction cup, when the bottom of the suction cup abuts against the operating platform, the suction cup can fix the support block connected to the mounting plate and the operating platform, thereby preventing the hole position and dimension inspection device from being easily displaced during use, making it more convenient to use.

[0017] Preferably, a threaded pin is inserted into the inner wall of the mounting plate, and one end of the threaded pin is fixedly connected to the top of the support block.

[0018] The effect achieved by the above components is: by setting the threaded pin and inserting the threaded pin into the inner wall of the mounting plate, the threaded pin can limit the mounting plate, which is helpful to prevent the mounting plate from separating from the support block.

[0019] Preferably, a nut is provided on the outer surface of the threaded pin, and the outer surface of the threaded pin is threadedly inserted into the inner wall of the nut.
