Description

Technical Field

[0001] This utility model relates to the field of measuring tool technology, specifically to a large-size outer diameter caliper clamping device. Background Technology

[0002] A caliper gauge is a measuring tool with two legs or jaws used for measuring distances, primarily in the field of machining. It is used to inspect the smoothness of shafts as limit gauges. They are generally divided into internal and external caliper gauges. They can be adjusted to measure thickness, diameter, bore, and distances between surfaces.

[0003] Publication number CN214390554U discloses a large-diameter caliper clamping device. This device, through a series of structural features, effectively prevents dust from flying during crushing and allows for multiple crushing operations to achieve more thorough pulverization of the ore. However, this device can only attract and extract dust and debris generated during ore crushing; some dust still falls below along with the ore fragments during use, affecting the overall quality of the crushed product and requiring further cleaning and filtration. Therefore, we propose a large-diameter caliper clamping device. Utility Model Content

[0004] To address the problems in the existing technology, this utility model provides a large-size outer diameter caliper clamping device.

[0005] The technical solution adopted by this utility model to solve its technical problem is a large-size outer diameter caliper clamping device, including an outer diameter caliper frame. An installation module is fixedly connected to the bottom of the inner walls on both sides of the outer diameter caliper frame. A calibration groove, a positioning groove and a connecting slot are opened in the center of the side of the installation module away from the outer diameter caliper frame. A plug-in card is detachably installed inside the connecting slot. The plug-in card is fixedly connected to the side wall of the fixing member. The fixing member is fixedly connected to the side wall of the fixing handle. A rotating connecting member is rotatably connected to the end of the fixing handle away from the fixing member. A rotating measuring handle is assembled on the side of the rotating connecting member away from the fixing handle.

[0006] The side wall of the fixed handle has a through hole, and a connecting plate is inserted through the through hole. A limiting sliding rod is fixedly connected to one side of the connecting plate, and the side of the limiting sliding rod away from the connecting plate is fixedly connected to a threaded connecting plate. A threaded hole is opened in the center of the threaded connecting plate, and the threaded hole is threaded to the outer periphery of the threaded rod.

[0007] By adopting the above technical solution, the part to be tested is first calibrated. The rotating measuring handle is rotated synchronously with the threaded rod, causing the threaded plate with the threaded hole on its outer periphery to move under the restriction of the fixed handle and the limiting sliding rod. The fixed handle is rotatably connected to the rotating measuring handle through the rotating connector, thereby pushing the through hole opened in the side wall of the fixed handle of the connecting plate to extend or retract, completing the calibration and adjustment of the part corresponding to the connecting plate, and controlling the spacing of the clamping arms. Then, the plug-in card, positioning plug and connecting plate are aligned with the connecting card slot, calibration slot and positioning slot respectively and inserted to connect the fixing part on the side wall of the fixed handle to the installation module. Then the outer diameter caliper frame is operated to control the clamping arms to detect the outer diameter of the part.

[0008] Specifically, the limiting sliding rod is slidably connected to the inner sliding groove of the fixed handle.

[0009] By adopting the above technical solution, the limiting sliding rod is used to move within the fixed handle as the measuring handle rotates.

[0010] Specifically, the screw hole plate and the connecting plate are slidably connected to the inside of the fixed handle via a limiting sliding rod.

[0011] By adopting the above technical solution, the screw hole plates and connecting plates on both sides are moved inside the fixed handle by the limiting sliding rod.

[0012] Specifically, the plug-in card is in an outwardly expanding shape and is interference-fitted with the connecting card slot.

[0013] By adopting the above technical solution, the fixing handle is installed in the middle of the installation module through an interference fit.

[0014] Specifically, a limiting plate for limiting the range of contraction or extension is fixedly connected to the side of the threaded rod away from the rotating measuring handle.

[0015] By adopting the above technical solution, the maximum displacement range of the screw hole plate is limited by the limiting plate.

[0016] Specifically, a positioning plug is fixedly connected to the center of one side of the connecting plate, and the positioning plug is inserted into the inside of the positioning groove.

[0017] By adopting the above technical solution, the connecting plate and the installation module are connected by inserting a positioning plug into the positioning slot.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] The technical solution of this application calibrates according to the part to be tested. Rotating the measuring handle synchronously with the threaded rod causes the threaded plate with the threaded hole on its outer periphery to move under the restriction of the fixed handle and the limiting sliding rod. The fixed handle is rotatably connected to the measuring handle through the rotating connector, thereby pushing the through hole opened in the side wall of the fixed handle of the connecting plate to extend or retract, completing the calibration and adjustment of the connecting plate corresponding to the part, controlling the spacing of the clamping arms. Then, the plug-in card, positioning plug and connecting plate are aligned with the connecting card slot, calibration slot and positioning slot respectively and inserted to connect the fixing part on the side wall of the fixed handle to the installation module. Then the outer diameter caliper frame is operated to control the clamping arms to detect the outer diameter of the part. Attached Figure Description
