DETAILED DESCRIPTION

[0021] Clearly, the described embodiments are merely a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] In the description of the present utility model, it is understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are merely for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the indicated device or element must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present utility model.

[0023] The main purpose of the present utility model is to fine-tune the lifting of the swing head assembly support 20 based on the A / C swing head geometry precision detection device designed, to meet the fine-tuning lifting requirement of the swing head assembly support 20 during the geometry precision detection of the A / C swing head 40 geometry precision detection device.

[0024] Specifically, in the present embodiment, reference is made to the accompanying drawings Figures 1-3 A fine-tuning structure for an A / C swing head geometry precision detection device is provided, which is suitable for the A / C swing head 40 geometry precision detection device, and is overall fitted on the bottom plate 201 of the swing head assembly support 20 of the A / C swing head geometry precision detection device, and is used for locally fine-tuning and lifting the swing head assembly support 20, wherein the swing head assembly support 20 can be used for mounting the A / C swing head 40.

[0025] In the present embodiment, the fine-tuning structure 10 includes an adjusting column 101 and a backing plate 102, the adjusting column 101 is provided with external threads, the adjusting column 101 is threadedly connected to the threaded hole 2011 of the bottom plate 201 of the swing head assembly support 20, the bottom of the bottom plate 201 is provided with a slot 2012 for inserting the backing plate 102, the threaded hole 2011 is also connected to the inner end of the slot 2012, the bottom of the adjusting column 101 abuts against the backing plate 102, and the top of the adjusting column 101 extends out of the threaded hole 2011 and is fastened together with the backing plate 102 through a connecting fastener 103.

[0026] Through the above-mentioned fine-tuning structure 10, under the premise that the bottom of the adjusting column 101 has abutted against the backing plate 102, continuing to rotate the adjusting column 101 can realize the fine-lifting of the bottom plate 201 at the adjusting column 101, thereby realizing the fine-tuning and lifting of the swing head assembly support 20.

[0027] It should be noted that in the present embodiment, the detection platform 30 of the A / C swing head geometric accuracy detection device is made of marble, which is thick and rectangular in shape and has a flat top surface 301. At this time, the swing head assembly bracket 20 is installed and connected to one end of the top of the detection platform 30 by screws (not labeled), which is equivalent to being offset to one end of the top of the detection platform 30. In this way, the other end of the detection platform 30 is left with enough detection space. It should be noted that in the present embodiment, the length direction of the swing head assembly bracket 20 is consistent with the width direction of the detection platform 30, which can avoid occupying the top surface area of the detection platform 30 along the length direction and leave enough space for detection.

[0028] In addition to the bottom plate 201, the swing head assembly bracket 20 also includes an installation vertical plate 202, which is basically constructed as a rectangular plate and is basically arranged in the middle of the top of the bottom plate 201. The length direction of the installation vertical plate 202 is consistent with the length direction of the bottom plate 201. At this time, the screws are basically arranged near the two sides of the installation vertical plate 202 to install and connect the bottom plate 201 to the top of the detection platform 30. As can be seen, the screws used to install and connect the bottom plate 201 are not arranged at the four corners of the bottom plate 201, and the fine adjustment structure 10 is arranged near the four corners of the bottom plate 201. In this way, the four corners of the bottom plate 201 are not tightly connected to the top of the detection platform 10 by the screws, so that the four corners can be locally lifted. The lifting here can be understood as lifting a small distance.

[0029] As for the fine adjustment structure 10, in the present embodiment, the top of the adjustment column 101 is also provided with a pressure cap 104, and the pressure cap 104, the adjustment column 101 and the pad plate 102 are connected by a connecting fastener 103. Specifically, the pressure cap 104 is constructed in the following style, which has a structure of a pressure plate 1041 and a surrounding plate 1042 arranged along the periphery of the pressure plate 1041, so that the pressure cap 104 is constructed as an open upward structure. Compared with ordinary gaskets, this structure of the pressure cap 104 has a surrounding plate 1042 structure, which improves the overall strength. In addition, the pressure cap 104 forms an upward opening, and its outer diameter can be larger than the outer diameter of the adjustment column 101. Therefore, the pressure cap 104 can protect the adjustment column 101 well during actual use or handling operation.

[0030] It should be noted that the connecting fastener 103 in the present embodiment can be a bolt. Specifically, after the pressure cap 104, the adjustment column 101 and the pad plate 102 are assembled, corresponding upper and lower connecting holes (not labeled) are arranged in sequence, which can be screwed into the bolt to sequentially connect the three into a whole.

[0031] Specifically, in the embodiment, the bottom of the base plate 201 is directly provided with the slot 2012, and the slot 2012 is configured as a rectangular slot, and the pad plate 201 is configured as a rectangular plate. After the slot 2012 is directly provided on the base plate 201, it is not necessary to be provided on the detection platform 30, so that the detection platform 30 can be prevented from being damaged.

[0032] In order to facilitate the rotation of the adjusting column 101, the outer side wall of the adjusting column 101 extending out of the top of the threaded hole 2011 is configured as an outer hexagonal structure for wrench operation, so that when the adjusting column 101 is rotated, the rotation operation can be conveniently realized due to the presence of the outer hexagonal structure.

[0033] In actual operation, the adjusting column 101 needs to be screwed to the bottom in the threaded hole 2011, and the bottom of the adjusting column 101 needs to abut against the top surface of the pad plate 102. When fine adjustment of lifting is required, the connecting fastener 103 is in an unscrewed state at this time, and the adjusting column 101 can be further screwed in by a wrench, but the adjusting column 101 cannot be actually screwed in due to the blockage of the pad plate 102. At this time, the base plate 201 connected with the adjusting column 101 by screwing is locally lifted to realize local fine lifting of the swing head assembly support 20. When the fine lifting height is in place, the screwing action of the adjusting column 101 is stopped, and then the connecting fastener 103 is screwed in place to realize the fastening of the cap 104, the adjusting column 101 and the pad plate 102, so that the three are connected together.

[0034] In the embodiment, the fine adjustment structure 10 has a relatively easy-to-operate overall structure, and the pad plate 102 is specially provided to prevent the bottom of the adjusting column 101 from directly abutting against the top of the detection platform 30 to cause damage to the detection platform 30, thereby protecting the detection platform 30. After the cap 104 is provided, it can function as a gasket to facilitate the fastening and connection of the adjusting column 101 and the pad plate 102, and because the outer diameter of the cap 104 is greater than the outer diameter of the adjusting column 101, the cap 104 can also function as a top protection for the adjusting column 101.

[0035] Because the fine adjustment structure 10 is basically located at the four corners of the base plate 201 and needs to be away from the fastening and mounting position of the base plate 201, that is, the fastening and mounting position of the swing head assembly support 20 on the detection platform 30. Therefore, in the embodiment, the fine adjustment structure 10 is provided in four groups, two of which are located on one side of the mounting vertical plate 202, and the other two are located on the other side of the mounting vertical plate 202. The fine adjustment structures 10 on the two sides of the mounting vertical plate 202 are symmetrically distributed, and the fine adjustment structures 10 on the same side of the mounting vertical plate 202 are symmetrically distributed with respect to the mounting hole 2021 (a U-shaped hole with an upper opening) on the mounting vertical plate 202. Therefore, through the above arrangement, fine adjustment and lifting can be realized at the positions required for fine adjustment and lifting.

[0036] Considering that the bottom plate 201 has a certain thickness, although the local micro-lifting is carried out, it is also necessary to be convenient to realize, and in addition, the top of the bottom plate 201 cannot be excessively cut and damaged, therefore, in the embodiment, the bottom plate 201 is provided with an adjusting blind hole 50 extending downward from the top surface to the bottom of the bottom plate 201 at the inner side close to the micro-adjusting structure 10. The adjusting blind hole 50 is arranged close to the micro-adjusting structure 10, and when the micro-lifting is carried out, the adjusting blind hole 50 is equivalent to forming a local cutting, so that the bottom plate 201 obtains a certain elastic bending force at the adjusting blind hole 50 when the micro-adjusting structure 10 is operated, which is beneficial to the local micro-lifting. The opening of the above-mentioned adjusting blind hole 50 does not form a too large size damage on the bottom plate 201, and because it is a hole, it is also easy to process and form.

[0037] Considering the limitation of the function of the adjusting blind hole 50, in the embodiment, it is also particularly strengthened, specifically, the bottom plate 201 is also provided with a recess cavity 2013 extending upward from the bottom below the adjusting blind hole 50, one side of the recess cavity 2013 is arranged in vertical alignment with the adjusting blind hole 50, and the other side of the recess cavity 2013 extends to the inner side of the bottom plate 201 beyond the adjusting blind hole 50. It should be noted that the recess cavity 2013 is arranged at the bottom of the bottom plate 201, and does not damage the top of the bottom plate. And after the recess cavity 2013 is arranged, the bottom plate 201 forms an upper and lower cutting at the local micro-lifting, and the thickness of the middle connecting part is much thinner than the original thickness of the bottom plate 201, which can multiply the increase of the micro-adjusting value when the micro-adjusting structure 10 carries out the local micro-lifting. It can be seen that on the basis of the adjusting blind hole 50, the recess cavity 2013 is arranged, and the double cooperation of the two achieves a significant increase in effect.

[0038] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited thereto, any person skilled in the art within the technical range disclosed by the present application, according to the technical scheme and the inventive concept of the present application, can be equivalent to replace or change, which should be covered in the protection scope of the present application.
