[0025] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0026] The utility model provides Figure 1-5 A flange hole position accuracy detection device shown in the figure comprises a base 1, and columns 13 are fixedly installed at the four corners of the bottom of the base 1 by bolts, and the ends of the columns 13 are fixedly connected to the base 1 by bolts, so that the columns 13 provide a stable support foundation for the entire detection device, ensuring the stability and accuracy during the measurement process, and a motor 2 is arranged below the bottom center of the base 1, and a support rod 3 is arranged above the base 1, and a cross frame 4 is fixedly installed on the top of the support rod 3, and the structure of the measuring component is installed by the cross frame 4, and the cross frame 4 is supported by the support rod 3;
[0027] A guide groove 41 is provided at the bottom of the horizontal frame 4, a convex block 43 is installed in the guide groove 41, the convex block 43 is adapted to the guide groove 41, an extension rod 44 is fixedly installed at the bottom of the convex block 43, a pen core 45 is provided at the bottom end of the extension rod 44, and the pen core 45 is driven by the horizontal frame 4 to make a circular motion on the upper surface of the flange, so that a line can be drawn on the upper surface of the flange for easy observation;
[0028] A through slot is provided at the top of the horizontal frame 4, and the through slot is connected with the guide slot 41, the length of the guide slot 41 is equal to that of the through slot, and a pointer 46 is vertically fixedly installed on the top of the protrusion 43. Since the pointer 46 is vertically aligned with the pen core 45, the position of the pen core 45 can be conveniently determined by the correspondence between the position of the pointer 46 and the scale 42.
[0029] Furthermore, in the above technical solution, a scale 42 is fixedly installed on one side of the top of the cross frame 4, a pointer 46 passes through the through slot and is located on one side of the scale 42, and the starting point of the scale 42 is the center position of the end of the cross frame 4 at one end of the support rod 3. Through the coordinated design of the pointer 46 and the scale 42, the operator can read the measurement results intuitively, thereby improving the accuracy and efficiency of the measurement.
[0030] Furthermore, in the above technical solution, a flange groove 11 is opened on the top of the base 1, and the flange groove 11 is used to place the flange. A through hole 14 is opened in the center of the flange groove 11, and the output end of the motor 2 is located above the through hole 14. Notches 12 are opened on both sides of the base 1 and connected to both sides of the flange groove 11, and the flange can be easily removed from the flange groove 11 through the notch 12.
[0031] Furthermore, in the above technical solution, a connecting seat 21 is fixedly installed at the output end of the motor 2, a threaded hole 22 is opened at the top of the connecting seat 21, and the connecting seat 21 is located above the through hole 14. The lower end of the support rod 3 is threadedly connected to the threaded hole 22 of the connecting seat 21, and one side of the upper end of the support rod 3 is a planar structure. The connection between the support rod 3 and the threaded hole 22 sets the support rod 3 and the connecting seat 21 into a detachable structure, thereby enabling the support rod 3 and the connecting seat 21 to be quickly disassembled and assembled.
[0032] Furthermore, in the above technical solution, support members are fixedly installed around the bottom of the motor 2, and the motor 2 is fixedly installed under the base 1 by the support members. The connecting seat 21 and the output end of the motor 2 are detachable mounting structures. Since the middle hole of the flange is sleeved on the connecting seat 21 and is adapted to the connecting seat 21, when flanges of different sizes are placed in the flange groove 11, connecting seats 21 of different sizes are adjusted and replaced according to the flanges of different sizes.
[0033] Furthermore, in the above technical solution, a socket is provided at the lower end of the extension rod 44, and the refill 45 is inserted into the socket. A top screw is provided on the outer wall of one side of the lower end of the extension rod 44 and at a position corresponding to the socket. The top of the refill 45 is aligned with the top screw, and since the socket provided at the lower end of the extension rod 44 is of sufficient length, the height of the refill 45 in the socket can be adjusted according to flanges of different thicknesses.
[0034] The working process of the flange hole position accuracy detection device provided by the utility model when in use is as follows:
[0035] After the equipment is installed and placed, the flange is placed in the flange groove 11 of the base 1, ensuring that the flange is in a suitable position, and then the support rod 3 is installed above the connecting seat 21, and then the protrusion 43 with the extension rod 44 is installed into the guide groove 41 of the cross frame 4. Since the cross frame 4 is made of iron material and the protrusion 43 is a magnetic material, the protrusion 43 can be adsorbed in the guide groove 41 of the cross frame 4, and the position of the protrusion 43 in the guide groove 41 can also be adjusted at will.
[0036] After the cross frame 4, extension rod 44 and other structures are installed, the pen core 45 is installed at the bottom of the extension rod 44, and the lower end of the pen core 45 is fitted with the upper surface of the flange, and the position of the pen core 45 in the insertion hole at the lower end of the extension rod 44 is adjusted and fixed by a top screw, and then the center position of a hole on the flange is determined first, and then the position of the protrusion 43 in the guide groove 41 is adjusted, so that the pen core 45 at the lower end of the protrusion 43 is aligned with the center of the hole, and then the motor 2 is started to control the support rod 3, and the support rod 3 drives the rotation of the cross frame 4 and other structures, so that one end of the pen core 45 takes the center position of the flange as the center point and the center position of a hole as the end point, and makes a circular motion on the upper surface of the flange, and then the pen core 45 draws a circular mark on the upper surface of the flange, and then compares whether the center of each of the remaining holes is deviated from the circular mark, so as to determine whether there is a deviation in the position of other holes.
[0037] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
