Abstract
Description
Technical Field
[0001] The utility model relates to the field of detection auxiliary equipment, in particular to a hole center height detection device. Background Art
[0002] Currently, raw material inspection often involves checking the center height and spacing of part holes. Existing methods for these two measurements typically use center-to-center calipers or vernier calipers. However, due to structural limitations, center-to-center calipers cannot measure hole spacings smaller than the minimum distance between the two jaws, and measuring the center height of a single hole is extremely inconvenient. Vernier calipers cannot accurately locate reference points when measuring hole spacing or hole center height, resulting in large measurement errors. Utility Model Content
[0003] In response to the above-mentioned problem, the present utility model proposes a hole center height inspection device, in which a standard cylinder is set by a slider, and clamping countersunk holes are opened on the standard cylinder, the first side block and the second side block. It can be used to inspect whether the height of a single hole meets the requirements, and can also inspect whether the center distance of double holes meets the requirements.
[0004] The technical solutions adopted by this utility model are as follows:
[0005] A hole center height inspection device includes a base, a guide rod, a slider and a standard cylinder, wherein a first side stop and a second side stop are respectively provided at both ends of the base, the guide rod is arranged between the first side stop and the second side stop, the slider has two pieces, both of which are slidably arranged on the guide rod, and the two sliders are located between the first side stop and the second side stop, each slider is detachably provided with one of the standard cylinders, and the standard cylinder, the first side stop and the second side stop are all provided with clamping countersunk holes.
[0006] It should be noted in advance that this device is suitable for screening large quantities of parts and is not suitable for inspection of precise dimensions.
[0007] In this inspection device, clamping countersunk holes are provided on the standard cylinder, the first side stop and the second side stop. The bottom of the clamping countersunk hole is roughly conical. The clamping countersunk hole is used to cooperate with the center distance caliper. When the position of the slider on the base is temporarily locked, the center distance caliper can be used to measure the distance between the two standard cylinders, the distance between the standard cylinder and the first side stop, and the distance between the standard cylinder and the second side stop.
[0008] When using this device, for parts that need to detect the height of a single hole, you only need to put the hole on the standard cylinder, and then observe the distance between the edge of the part and the first side stop or the second side stop to determine whether the height of the hole on the part is qualified. The two holes are respectively fitted with the standard cylinders, and then the distance between the two standard cylinders is measured with a caliper to determine whether the distance between the two holes on the part meets the requirements.
[0009] To sum up, this device sets the standard cylinder through a slider, and provides clamping countersunk holes on the standard cylinder, the first side stop and the second side stop, which can be used to check whether the height of a single hole meets the requirements, and whether the center distance of the double holes meets the requirements.
[0010] Optionally, a locking screw is provided on the slider.
[0011] A locking screw is provided to hold the base in place, preventing the slider from sliding on the guide rod and locking the slider relative to the base. When the slider is locked, the standard cylinder is fixed relative to the first and second side blocks, and the two standard cylinders are fixed relative to each other, allowing for rapid part inspection.
[0012] Optionally, there are two guide rods, and the two guide rods are in parallel.
[0013] Two guide rods are provided, and each slider is slidably matched with the two guide rods, which can improve the stability of the slider when sliding on the guide rods.
[0014] Optionally, each standard cylinder is sleeved with an O-ring.
[0015] Optionally, each standard cylinder is sleeved with a plurality of O-rings, and the O-rings on the same standard cylinder are in a parallel and non-contact state.
[0016] The purpose of setting the O-ring on the standard cylinder is to prevent the side part from shaking after the side part is inserted into the standard cylinder through its own through-hole.
[0017] Optionally, an anti-slip pad is further included, and the anti-slip pad is arranged on the base.
[0018] The specific anti-slip pad includes but is not limited to a rubber pad or a silicone pad. The purpose of providing the anti-slip pad is to prevent the base itself from slipping during use.
[0019] Optionally, the guide rod is perpendicular to the first side stop and the second side stop.
[0020] Optionally, the first side stop and the second side stop are in parallel.
[0021] The beneficial effect of the present invention is that a standard cylinder is set by a slider, and clamping countersunk holes are opened on the standard cylinder, the first side block and the second side block, which can be used to check whether the height of a single hole meets the requirements, and whether the center distance of the double holes meets the requirements.

[0036] In this inspection device, a clamping countersunk hole 2 is provided on the standard cylinder 6, the first side stop and the second side stop. The bottom of the clamping countersunk hole 2 is roughly conical. The clamping countersunk hole 2 is used to cooperate with the center distance caliper.
