[0002] A multi-angle length comparator is a type of measuring instrument. Its basic principle is based on the standard definition of an angle, which is the angle between two intersecting lines. Through high-precision sensors and mechanical structures, the instrument can accurately sense and quantify the size of the angle.

[0003] The clamping structure design of the existing comparator for clamping the workpiece is relatively simple, and the clamping effect is relatively stable for workpieces of conventional shapes. However, for special-shaped workpieces, due to its limited clamping angle, it cannot adapt to the distribution surface of the special-shaped workpiece, resulting in insufficient clamping. Therefore, a new clamping structure is needed to solve the above problem. Utility Model Content

[0009] Furthermore, the adaptive clamping assembly also includes a receiving groove and a receiving rod. The receiving grooves are formed on both sides of the first receiving plate, and the receiving rods are fixedly connected to both sides of the second receiving plate. The receiving rods are movably inserted into the receiving grooves.

[0010] Furthermore, the adaptive clamping assembly also includes a rectangular placement groove, an adjustment spring, a rectangular connecting column and a rectangular through groove. A rectangular placement groove is opened on the side of the receiving rod. One end of the adjustment spring is fixedly connected to the intersection of the rear side of the rectangular placement groove and the receiving rod, and the other end of the adjustment spring is fixedly connected to the rectangular connecting column. Rectangular through grooves are opened on both sides of the first receiving plate, and rectangular connecting columns are movably inserted into the rectangular through grooves.

[0030] Measurement comparator main body 101;

[0031] Adaptive clamping assembly, the adaptive clamping assembly includes a first receiving plate 201, a second receiving plate 202, a first circular adjustment groove 203, a second circular adjustment groove 204, a plastic sphere 205 and a clamping rod 206.

[0032] The measuring comparator body 101 is used to measure and compare workpieces. The setting of the first receiving plate 201 and the second receiving plate 202 provides a guarantee for the opening of the first circular adjustment groove 203 and the second circular adjustment groove 204. The setting of the plastic sphere 205 can drive the clamping rod 206 to rotate at multiple angles. The clamping rod 206 is used to clamp the workpiece to be measured.

[0033] The adaptive clamping assembly further includes a receiving groove 207 and a receiving rod 208. The receiving grooves 207 are formed on both sides of the first receiving plate 201. The receiving rods 208 are fixedly connected to both sides of the second receiving plate 202. The receiving rods 208 are movably inserted into the receiving grooves 207.

[0034] The receiving groove 207 and the receiving rod 208 cooperate with each other to realize the movable connection between the second receiving plate 202 and the first receiving plate 201 .

[0035] The adaptive clamping assembly also includes a rectangular placement slot 209, an adjustment spring 2010, a rectangular connecting column 2011, and a rectangular through-slot 2012. The rectangular placement slot 209 is provided on the side of the receiving rod 208. One end of the adjustment spring 2010 is fixedly connected to the intersection of the rear side of the rectangular placement slot 209 and the receiving rod 208. The other end of the adjustment spring 2010 is fixedly connected to the rectangular connecting column 2011. Rectangular through-slots 2012 are provided on both sides of the first receiving plate 201. The rectangular connecting column 2011 is movably inserted into the rectangular through-slot 2012.

[0036] The opening of the rectangular placement groove 209 provides a guarantee for the connection between the adjustment spring 2010 and the rectangular connecting column 2011. The setting of the adjustment spring 2010 provides a guarantee for the extension and contraction of the rectangular connecting column 2011. The rectangular connecting column 2011 and the rectangular through groove 2012 are used in conjunction to realize the adjustment and fixation between the first supporting plate 201 and the second supporting plate 202.

[0037] The sum of the lengths of the adjustment spring 2010 and the rectangular connecting column 2011 is greater than the depth of the rectangular placement groove 209;

[0038] The size setting between the above components can ensure that the rectangular connecting column 2011 protrudes and connects to the first receiving plate 201.

[0039] The anti-scratch assembly includes a receiving tube 301 and a buffer spring 302. The side of the plastic sphere 205 is fixedly connected to the receiving tube 301. The receiving tube 301 is movably connected to the buffer spring 302 and the clamping rod 206.

[0040] The arrangement of the receiving tube 301 provides a guarantee for the placement of the buffer spring 302 and the clamping rod 206 .

[0041] The anti-scratch assembly also includes a limit block 303 and a limit groove 304. The limit groove 304 is formed around the receiving tube 301. One end of the clamping rod 206 is fixedly connected to the limit block 303. The limit block 303 is movably inserted into the limit groove 304.

[0042] The limiting block 303 cooperates with the limiting groove 304 to limit the movement range of the clamping rod 206 and prevent the clamping rod 206 from separating from the receiving tube 301.

[0043] The length of the buffer spring 302 is smaller than the length of the receiving tube 301;

[0044] The size setting between the above components can prevent the clamping rod 206 from being subjected to excessive spring force.

[0045] The clamping end of the clamping rod 206 is arranged in a truncated cone shape;

[0046] The shape of the clamping rod 206 can reduce and concentrate the clamping force at the clamping end, thereby further improving the clamping effect.

[0047] Working principle: First, place the workpiece to be measured on top of the measuring comparator body 101, then adjust the angle of the clamping rod 206 according to the shape of the workpiece, rotate the clamping rod 206, and then drive the plastic ball 205 to rotate in the first circular adjustment groove 203 and the second circular adjustment groove 204. When it is rotated to the appropriate position, one end of the clamping rod 206 is firmly in contact with each surface of the workpiece, and the second receiving plate 202 is moved toward the first receiving plate 201. At this time, the receiving rod 208 drives the adjustment spring 2010 and the rectangular connecting column 2011 to be in the receiving groove 207. When the rectangular connecting column 2011 moves to the rectangular through groove 2012, the adjusting spring 2010 pushes the rectangular connecting column 2011 into the rectangular through groove 2012, and then moves the receiving component at the bottom of the first receiving plate 201 to drive the clamping rod 206 to be in close contact with the workpiece, and then uses the components on the measuring comparator body 101 to measure. This step can achieve a firm clamping of special-shaped workpieces, thereby improving the applicability of the measuring comparator body 101, and at the same time can protect the workpiece during the clamping process.

[0048] The above-described embodiments merely illustrate several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make numerous variations and improvements without departing from the spirit of the present invention, all of which fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
