Embodiment

[0016] image 3 is the schematic diagram of the structure of the bolt to be measured in this example, by image 3 It can be seen that the bolt 4 to be measured is a hexagonal bolt, and the bolt head of the hexagonal bolt has a slot 6 symmetrical to the bolt, which is the object to be measured in this example. The method in this example is used to measure the symmetry of the slot relative to the shank of the bolt.

[0017] Figure 4 is a schematic diagram of the measurement method in the prior art, by Figure 4 It can be seen that the measuring method in the prior art is: first place the V-shaped iron 8 on the working platform 7, then place the rod portion of the bolt 4 to be tested in the V-shaped groove of the V-shaped iron, and rotate the bolt 4 to be measured to make a straight line. Tank 6 is in a horizontal state. Then insert the feeler gauge 9 into the slot 6 of the bolt 4 to be tested; set up a meter frame 10 next to the V-shaped iron, and install a dial indicator 1...

Abstract

The invention discloses a method for measuring the symmetry degree of a bolt slot and a tool clamp. The method comprises that the tool clamp which is specially used for measuring the symmetry degree of the bolt slot is processed, the tool clamp is cylindrical, and provided with a central hole whose one end includes a counterbore, during measurement, a bolt to be measured is inserted into the central hole through the end with the counterbore, the head of the bolt is sunk into the counterbore, a vernier caliper measures the vertical distance from one side of the slot to the highest point of the outer cylindrical surface of the tool clamp, the vertical distance from the other side of the slot to the highest point of the outer cylindrical surface of the tool clamp is measured in the same method, and the difference between measurement data is the symmetry degree of the slot relative to the rod portion of the bolt. Compared with a method in the prior art, the method is much simpler, the structure of the tool clamp is very simple, the measuring efficiency is greatly improved, and the measuring precision can be improved.

Description

technical field [0001] The invention relates to a method for measuring the symmetry of a slot of a bolt and a fixture, belonging to the technical field of mechanical part measurement. technical background [0002] At present, the following method is used to measure the symmetry of the bolt slot relative to the shaft: first place a V-shaped iron on the flat plate, then place the shaft of the slotted bolt in the V-groove of the V-shaped iron, and rotate the bolt to make the slot The slot is horizontal. Then insert the feeler gauge into the slot of the bolt; set up the meter frame next to the V-shaped iron, and install the dial indicator on the meter frame; measure the value on the upper surface of the feeler gauge through the dial indicator, and record the reading; then rotate the bolt 180 Measure the reading on the other side of the feeler gauge according to the above method, and the difference between the two readings is the symmetry based on the bolt shank. The existing m...
