Description

Technical Field

[0001] The utility model relates to the technical field of mechanical dimension measurement, in particular to a measurement device for mechanical dimensions. Background Art

[0002] Mechanical dimension measurement devices are key equipment for accurately measuring and evaluating the dimensions, shapes, and positions of mechanical components, and are widely used in manufacturing, engineering fields, and scientific research. These devices are based on advanced sensor technologies and precise data processing capabilities, and can provide high-precision and reliable measurement results, which are crucial for ensuring product quality and engineering safety.

[0003] Existing measurement devices for mechanical dimensions can only measure one side. When measuring another side, it is necessary to adjust the angle of the bottom workpiece, which is rather cumbersome in operation and affects the detection efficiency. Therefore, a measurement device for mechanical dimensions is proposed.

[0004] A mechanical dimension measurement fixture disclosed in the publication number CN213917909U. Although this mechanical dimension measurement fixture relates to the technical field of mechanical dimension measurement and includes a base and a clamping device, the clamping device is arranged on the inner wall of the base. The clamping device includes a mounting rod, one side of the mounting rod close to the base is slidably connected to the inner wall of the base, a sliding rod is slidably connected to the inner wall of the mounting rod, the side of the sliding rod away from the mounting rod is slidably connected to the inner wall of the base, a slider is slidably connected to the side of the mounting rod away from the base, and the lower surface of the slider abuts against the inner wall of the base. In the present utility model, most measurement fixtures on the market currently clamp objects through bolts and pressing blocks, and local stress on the surface of the object is likely to be severe during the use of the device, causing damage to the surface of the measured object and affecting the accuracy of the device measurement, which is not conducive to the normal use of the device. The use of this device effectively avoids the above problems and improves the stability of the device.

[0017] (III) Beneficial effects

[0018] The utility model provides a measuring device for mechanical dimensions, which has the following beneficial effects:

[0019] 1. For the measuring device for mechanical dimensions, through the settings of the driving mechanism and the longitudinal detection mechanism, when measuring, the workpiece is placed on the placement plate, and then the servo motor on one side is started. The servo motor drives the lead screw at the end to rotate, so that the two transverse measuring rods on the surface of the lead screw move relative to the lead screw, thereby driving the transverse fixing plate at the bottom to clamp the workpiece. Secondly, the hydraulic rods on both sides are started, and the hydraulic rods drive the push plate and the longitudinal fixing plate at the bottom of the push plate to move, which can clamp the periphery of the workpiece. At the same time, by observing the scale lines on the measuring frame and the transverse measuring rods, the length and width of the workpiece can be intuitively observed, and the length and width can be measured simultaneously, and the operation is relatively simple.

[0020] 2. For the measuring device for mechanical dimensions, through the setting of the gravity detection mechanism, when measuring the dimensions of the workpiece, the workpiece is placed on the placement plate. Since a gravity sensor is arranged on the surface of the placement plate, the gravity sensor can detect the weight of the workpiece and transmit the signal to the gravity controller on one side for processing. The gravity controller uploads the processed data to the display screen for display. While measuring the dimensions of the workpiece, the weight of the workpiece can also be detected, improving the versatility of the device. Description of the drawings
