[0016] Figure 1 This is a schematic diagram of the structure of the part to be tested.
[0017] Reference Figure 1The part 5 to be measured in this invention has two planes, surface A and surface B, extending in different directions at both ends. In this embodiment, the middle part of the part 5 has an enamel disc. In other embodiments, the middle part of the part 5 may also have a disc-shaped body of different shapes. When using a projector to measure production errors, the structure of these middle parts may interfere with the measurement of the angle between surface A and surface B due to the effect of shadow covering.
[0018] Figure 2 This is a schematic diagram of an auxiliary protractor for irregularly shaped workpieces according to an embodiment of the present invention.
[0019] Reference Figure 2 An auxiliary protractor for irregularly shaped workpieces according to an embodiment of the present invention includes: a base 1, an elastic element 2, a positioning element 3, and a pressure block 4. The base 1 is generally block-shaped, and a recessed wide surface on one side of the base 1 forms a limiting groove 11 for accommodating the part 5 to be measured. A positioning hole 12 is provided on the first side wall of the limiting groove 11, and a limiting hole 13 is provided on the second side wall of the limiting groove 11. One end of the positioning element 3 passes through the positioning hole 12 and abuts against the third side wall of the limiting groove 11 opposite to the first side wall. One end of the positioning element 3 is connected to the positioning hole 12 by a thread. The pressure block 4 is movably disposed on the positioning element 3, and the elastic element 2 is sleeved on the positioning element 3, with the elastic element 2 located between the pressure block 4 and the positioning element 3. During the angle test of the part, the pressure block 4 clamps the part 5 to be measured in the limiting groove 11 through the action of the elastic element 2, thereby making the first surface of the part 5 to be measured parallel to the end face of the pressure block 4. The operator only needs to measure the angle between the projection of the pressure block 4 and the second surface of the part 5 to complete the angle detection of the first and second surfaces of the part 5.
[0020] Figure 3 This is an exploded structural diagram of an auxiliary protractor for irregularly shaped workpieces according to an embodiment of the present invention.
[0021] Reference Figure 3Specifically, the positioning component 3 includes a first part 31 and a second part 32 coaxially connected. The diameter of the first part 31 is larger than the diameter of the second part 32, and the elastic element 2 is sleeved on the outer periphery of the second part 32. The outer periphery of the first part 31 is threaded. After the connecting key passes through the limiting groove 11, the end face of the second part 32 abuts against the third side wall inside the limiting groove 11, wherein the first side wall and the third side wall are parallel to each other. The first part 31 is fixed in the positioning hole 12 by the thread, thereby making the second part 32 stably set in the limiting groove 11. The pressure block 4 can move using the second part 32 as a guide rail, thereby fixing the part 5 to be tested. The elastic element 2 is sleeved on the second part 32, and one end of the elastic element 2 abuts against the first side wall, and the other end of the elastic element 2 abuts against the wide surface of the pressure block 4. In this embodiment, the elastic element 2 is a spring or rubber and other elastic components.
[0022] Furthermore, the limiting hole 13 includes a first region 131 and a second region 132 that are connected to each other. On the end face of the base 1, the area of the first region 131 is larger than the area of the second region 132, and the maximum width of the first region 131 is greater than the width of the second region 132. In this embodiment, the first region 131 is generally circular, and the second region 132 is generally rectangular. Furthermore, one of the center lines of the first region 131 and one of the center lines of the second region 132 are collinear.
[0023] Furthermore, the wide surface of the pressure block 4 is provided with a connecting hole 41 that matches the second part 32, and the narrow sides of the pressure block 4 protrude outwards to form guide posts. Specifically, the thickness of the pressure block 4 is less than the width of the second region 132 on the end face of the base 1. When assembling the pressure block 4, the operator needs to rotate the pressure block 4 around the guide post axis to adjust the overall orientation of the pressure block 4. After the pressure block 4 passes through the limiting hole 13 into the limiting groove 11, the operator rotates it again around the guide post axis to adjust the wide surface of the pressure block 4 to be parallel to the first side wall, so as to clamp and fix the part 5 to be tested later. In addition, during the assembly of the pressure block 4, the side of the pressure block 4 near the guide post is located in the first region 131, and the side of the pressure block 4 away from the guide post is located in the second region 132. Furthermore, after the pressure block 4 enters the limiting groove 11, the pressure block 4 can only rotate around the guide post axis when the guide post is located in the first region 131.
[0024] After installation, the operator first sets up the projector, aligning the wide surface of base 1 with the baseline on the projector screen. Then, the base 1 is rotated so that the B-side of the part to be tested 5 is aligned with the baseline on the projector screen. The angle between the A-side and B-side of the part to be tested 5 can then be read from the projector stage. Because the wide surface of base 1 is parallel to the wide surface of pressure block 4, and the wide surface of pressure block 4 remains in contact with the A-side of the part to be tested 5 after clamping and fixing it, the light-blocking effect of the irregular shape in the middle of the part to be tested 5 can be avoided when aligning the wide surface of the base with the baseline on the projector screen.
[0025] In summary, this utility model uses a positioning hole and a positioning element on the first side wall of the limiting groove to cooperate, thereby installing a spring between the first side wall and the pressure block. Under the action of the elastic element, the pressure block clamps the part to be tested, thereby keeping the pressure block against the first surface of the part to be tested, thus assisting the operator in measuring the included angle between the first and second surfaces of the part to be tested.
