Abstract
Description
Technical Field
[0001] The utility model relates to a tooling device for measuring the moment from a V-shaped ring groove to an end face, belonging to the technical field of machinery. Background Art
[0002] During the batch production of tool holders or parts with V-ring grooves, there are strict requirements on the size from the center of the V-ring groove to the end face or to the specified size, and it is necessary to measure it after each part is processed.
[0003] During the machining measurement process, using the pin gauge method requires first going to the inspection room, preparing gauge blocks, and superimposing the corresponding dimensions. The part is then placed on a taper shank fixture or a height block. Pin gauges are placed at both ends of the V-ring groove. A dial indicator is used to level the gauges. The gauge block dimensions are compared to the dial indicator values, and the radius of the pin gauge is subtracted to calculate the distance from the center of the V-ring groove to the specified end face or dimension. This method is time-consuming, subject to measurement errors, and inefficient. Furthermore, it is not possible to quickly measure and calculate allowances for each part in mass production. Summary of the Invention
[0004] In order to overcome the difficulties of existing measurement methods, the utility model provides a V-shaped ring groove to end face moment measurement fixture device, which solves the problem that timely measurement cannot be performed during mass production.
[0005] A V-shaped ring groove to end face moment measuring tool device, the guide shaft is connected to the lower part of the center hole of the gauge base body, the gauge rod fixing sleeve is connected to the upper center hole of the gauge base body, the gauge rod fixing sleeve and the gauge base body are fixed by a first fixed top screw, the shell rod of the dial indicator is connected to the center hole of the gauge rod fixing sleeve, the shell rod and the gauge rod fixing sleeve are fixed by a third fixed top screw, the lower end of the guide shaft is provided with a spring hole, the spring is connected in the spring hole, the cover is connected to the lower end of the gauge base body, one end of the spring contacts the cover, the cover is fixed to the gauge rod fixing sleeve by a second fixed top screw, the lower part of the gauge base body is provided with a through groove, the ball head measuring rod is connected to the through groove of the gauge base body, the lower part of the guide shaft is provided with a side hole, the side hole of the guide shaft is communicated with the spring hole of the guide shaft, one end of the ball head measuring rod is provided with a hole, the connecting top screw is connected to the hole of the ball head measuring rod, the other end of the connecting top screw contacts the spring, and the end of the ball head measuring rod contacts the groove of the test gauge.
[0006] During measurement, the standard gauge or workpiece and device are placed on a flat plate, and the ball head measuring rod contacts the workpiece and moves up and down, driving the guide shaft to move up and down, thereby driving the dial indicator rod in contact with the guide shaft to move and generate a numerical value.
[0007] The advantage of the present invention is that it can measure the V-ring groove to the end face or the specified size at any time. The main body has a fixed dial indicator rod device. The worker only needs to insert a dial indicator into the fixed shaft of the dial indicator rod until it contacts the guide shaft and fix it with the side screw. Place it on a flat plate, use a standard test gauge to zero it, remove the test gauge, put in the processed part to read the reading, and use the dial indicator reading to quickly measure whether the V-ring groove to the end face or the specified size is qualified; or use the dial indicator reading to calculate the V-ring groove allowance of the tool holder by the formula: V-ring groove inclined surface machining allowance = table reading / tan (V-ring groove single-side angle), or the machining allowance of the tapered shank: tapered shank single-side machining allowance = table reading × sin (single-side tapered shank angle), and then process it until it is qualified; the operation is simple during mass production. After the parts are machined, they do not need to be taken to the inspection room and can be measured near the machine tool. This realizes rapid measurement and numerical reading and calculation of each part at any time during mass production, which is convenient for workers to process and measure, ensuring the quality of parts while improving measurement speed and production efficiency.
