Dimension measuring device for precision machining

Abstract

The invention relates to the technical field of dimension measuring equipment for machining, and discloses a dimension measuring device for precision machining, which comprises an equipment base, and the bottom of the equipment base is fixedly connected with a plurality of supporting legs. When a moving block is separated from a threaded groove in an auxiliary rotating shaft, a first telescopic rod at one end of a rotating rod shrinks, the shrinkage elasticity of a telescopic spring at one end of the first telescopic rod is increased, and in this way, the interaction force between a clamping piece at one end of the first telescopic rod and the inner wall of the seamless steel pipe body is increased; therefore, the fixing effect of the clamping pieces on the seamless steel pipe body is enhanced, and the seamless steel pipe body can be kept stable when the measuring position is adjusted. On the other hand, the multiple clamping pieces expand towards the outer side of the fixing cylinder, the axis of the seamless steel pipe body and the axis of the fixing cylinder can be adjusted to be kept on the same axis, and therefore size measurement of the seamless steel pipe body is more accurate.

Description

Technical Field

[0001] The invention relates to the technical field of dimension measuring equipment for mechanical processing, in particular to a dimension measuring device for precision mechanical processing. Background Art

[0002] At present, for the measurement of the inner diameter of seamless steel pipes, workers usually use an inner diameter caliper to insert a certain distance into the steel pipe and manually measure the inner diameter of a specified position. Seamless steel pipes have various specifications. For the measurement of the inner diameter of steel pipes of different specifications, the distance of the inner diameter of the steel pipe inserted is also different. It is not easy to ensure the accuracy of the inner size of the pipe by inserting a handheld inner diameter caliper into the steel pipe for measurement, and the selection of the measurement point position is prone to deviation.

[0003] Most of the seamless steel pipe size measuring devices under the existing technology require too much manual participation. When measuring seamless steel pipes, the size measuring devices under the existing technology need to fix and clamp the steel pipes through a clamping mechanism because the sizes of seamless steel pipes of different specifications are different.

[0018] The present invention has the following beneficial effects:

[0019] (1) The present invention provides an auxiliary fixing mechanism. When the push plate slides along the limiting groove 1, the push plate drives the fixed cylinder to move toward the inside of the seamless steel tube body, and the push plate drives several rotating shafts inside to slide. The sliding of the rotating shaft drives the transmission gear 1 to slide along the spur teeth. At this time, the spur teeth drive the rotating shaft on the transmission gear 1 to rotate, and the rotating shaft drives the bevel gear 1 to rotate. The rotation of the bevel gear 1 drives the auxiliary rotating shaft on the bevel gear 2 to rotate. The rotation of the auxiliary rotating shaft drives the moving block at the other end of the auxiliary rotating shaft to slide along the thread groove toward the end close to the bevel gear 1. At this time, the moving block drives the telescopic rod 1 at one end of the rotating rod to expand toward the outside of the fixed cylinder, and the telescopic rod 1 drives the clamping piece to move close to the seamless steel tube body. When the moving block slides, the moving block drives the extrusion spring to contract. When the moving block is disengaged from the thread groove on the auxiliary rotating shaft, the moving block stops on the auxiliary rotating shaft. When the auxiliary shaft rotates in the opposite direction, the elastic force of the extrusion spring will squeeze the moving block into the threaded groove again, thereby facilitating the resetting of the auxiliary fixing mechanism. When the moving block is disengaged from the threaded groove on the auxiliary shaft, the telescopic rod at one end of the rotating rod contracts, and the contraction elastic force of the telescopic spring at one end of the telescopic rod increases. This arrangement is conducive to increasing the interaction force between the clamping piece at one end of the telescopic rod and the inner wall of the seamless steel pipe body, thereby facilitating the fixing effect of the clamping piece on the seamless steel pipe body, so that the seamless steel pipe body can remain stable when adjusting the measuring position; on the other hand, through the expansion of a plurality of clamping pieces toward the outside of the fixed cylinder, it is conducive to adjusting the axis center of the seamless steel pipe body and the axis center of the fixed cylinder to remain on the same axis, thereby making the size measurement of the seamless steel pipe body more accurate.

[0020] (2) According to the present invention, when the dimension measuring device for precision machining is used, the seamless steel tube body is first placed inside the feed trough on the top of the measuring platform. At this time, the driving motor is started, and the output end of the driving motor drives the output shaft to rotate. The output shaft drives a plurality of rotating shafts at one end of the transmission belt to rotate. The rotation of the rotating shaft drives the threaded rod to rotate. The rotation of the threaded rod drives the push plate to slide along the limit groove toward one end of the seamless steel tube body. The push plate slides to push the seamless steel tube body. This arrangement is conducive to adjusting the measuring position of the seamless steel tube body, thereby facilitating the measurement of the diameters of various positions of the seamless steel tube body.

[0021] (3) The present invention sets a measuring mechanism. When it is necessary to measure the outer wall diameter of a certain position of the seamless steel tube body, the driving motor is first stopped, and then the adjusting motor is started. The adjusting motor rotates to drive the rotating disk at one end of the adjusting shaft. The rotating disk rotates to drive the measuring rod inside the special-shaped groove to squeeze the reset spring one along the limit groove two. When the detection head at one end of the measuring rod contacts the outer wall of the seamless steel tube body, the adjusting motor stops rotating. This arrangement is conducive to several detection heads measuring the side wall of the seamless steel tube body at different positions. By setting an auxiliary pushing mechanism, when the pushing plate pushes the seamless steel tube body through the support body, the threaded rod one rotates to drive the threaded rod two to rotate. Since the pressure spring two is in a compressed state The second threaded rod is in a state of being pressed into the threaded groove on the second threaded rod by the elastic force of the second pressure spring. At this time, the second threaded rod drives the pushing rod at one end of the sliding block to slide toward the end close to the supporting body. The movement of the pushing rod drives the return spring 2 at one end of the pushing ring to contract. At this time, the pushing ring slides along the inner wall of the rotating cylinder. The pushing ring drives the extrusion base at one end of the extrusion rod to move toward the outer wall of the seamless steel pipe body, so that the cleaning sponge is squeezed against the outer surface of the seamless steel pipe body. This arrangement is conducive to the cleaning sponge on one side of the extrusion base clamping the outer surface of the seamless steel pipe body, thereby assisting in fixing the seamless steel pipe body, so that the seamless steel pipe body remains stable during size measurement, thereby reducing the measurement error of the device.

[0022] (4) The present invention sets a rotating cleaning mechanism. When the threaded rod 1 rotates and drives the threaded rod 2 to rotate, the threaded rod 2 drives the rotating rod to rotate. The rotation of the rotating rod drives the transmission gear 2 to rotate. The rotation of the transmission gear 2 drives the rotating cylinder on the gear ring to rotate. The rotation of the rotating cylinder drives several extrusion bases on the rotating cylinder to rotate. The rotation of the extrusion base drives the cleaning sponge to rub along the outer surface of the seamless steel pipe body. This arrangement is conducive to cleaning the outer surface of the seamless steel pipe body with the cleaning sponge, thereby avoiding the influence of impurities on the surface of the seamless steel pipe body on the measurement results.

[0023] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0049] A specific application of this embodiment is:

[0050] When using the dimension measuring device for precision machining, first place the seamless steel tube body 14 inside the feed trough 13 on the top of the measuring platform 12, then start the drive motor 201, the output end of the drive motor 201 drives the output shaft 202 to rotate, the output shaft 202 drives a number of rotating shafts 203 at one end of the transmission belt 204 to rotate, the rotating shaft 203 rotates and drives the threaded rod 206 to rotate, the threaded rod 206 rotates and drives the push plate 207 to slide along the limit groove 205 toward one end of the seamless steel tube body 14, the push plate 207 slides to push the seamless steel tube body 14, this arrangement is conducive to adjusting the measurement position of the seamless steel tube body 14, so as to facilitate the measurement of various positions of the seamless steel tube body 14 By setting the auxiliary fixing mechanism 3, when the push plate 207 slides along the limiting groove 1 205, the push plate 207 drives the fixing cylinder 301 to move toward the inside of the seamless steel pipe body 14, and the push plate 207 drives the internal plurality of rotating shafts 303 to slide, and the sliding of the rotating shaft 303 drives the transmission gear 1 304 to slide along the straight teeth 302, at this time, the straight teeth 302 drives the rotating shaft 303 on the transmission gear 1 304 to rotate, and the rotating shaft 303 drives the bevel gear 1 305 to rotate, and the rotation of the bevel gear 1 305 drives the auxiliary rotating shaft 306 on the bevel gear 2 307 to rotate, and the rotation of the auxiliary rotating shaft 306 drives the moving block 309 at the other end of the auxiliary rotating shaft 306 to move along the thread groove 308 toward one end close to the bevel gear 1 305 When the movable block 309 slides, the telescopic rod 402 at one end of the rotating rod 401 expands toward the outside of the fixed cylinder 301, and the telescopic rod 402 drives the clamping piece 404 to move closer to the seamless steel pipe body 14. When the movable block 309 slides, the movable block 309 drives the extrusion spring 310 to contract. When the movable block 309 is disengaged from the thread groove 308 on the auxiliary rotating shaft 306, the movable block 309 stops sliding on the auxiliary rotating shaft 306. At this time, the extrusion spring 310 is compressed and the elastic force increases. This arrangement is beneficial for the elastic force of the extrusion spring 310 to squeeze the movable block 309 into the thread groove 308 again when the auxiliary rotating shaft 306 rotates in the opposite direction, thereby facilitating the reset of the auxiliary fixing mechanism 3. When the movable block 309 is disengaged from the auxiliary rotating shaft 306, the movable block 309 stops sliding on the auxiliary rotating shaft 306. When the thread groove 308 on 06 is disengaged, the telescopic rod 402 at one end of the rotating rod 401 contracts, and the contraction elastic force of the telescopic spring 403 at one end of the telescopic rod 402 increases. This arrangement is conducive to increasing the interaction force between the clamping piece 404 at one end of the telescopic rod 402 and the inner wall of the seamless steel pipe body 14, thereby facilitating the clamping piece 404 to strengthen the fixing effect of the seamless steel pipe body 14, so that the seamless steel pipe body 14 can remain stable when adjusting the measuring position; on the other hand, by expanding a plurality of clamping pieces 404 toward the outside of the fixed cylinder 301, it is conducive to adjusting the axis of the seamless steel pipe body 14 and the axis of the fixed cylinder 301 to remain on the same axis, so that the size measurement of the seamless steel pipe body 14 is more accurate;

[0051] By setting the measuring mechanism 5, when it is necessary to measure the outer wall diameter of a certain position of the seamless steel pipe body 14, first stop the driving motor 201, then start the adjustment motor 502, the adjustment motor 502 rotates to drive the rotating disk 504 at one end of the adjustment shaft 503, the rotating disk 504 rotates to drive the measuring rod 508 inside the special-shaped groove 505 to squeeze the reset spring 1 507 along the limit groove 2 506, when the detection head 509 at one end of the measuring rod 508 contacts the outer wall of the seamless steel pipe body 14, the adjustment motor 502 stops rotating, and this setting is conducive to a plurality of detection heads 509 measuring seamless steel pipes at different positions The side wall of the seamless steel pipe body 14 is provided with an auxiliary pushing mechanism 6. When the pushing plate 207 pushes the seamless steel pipe body 14 through the support body 601, the threaded rod 1 206 rotates to drive the threaded rod 2 602 to rotate. Since the pressure spring 2 606 is in a compressed state, the elastic force of the pressure spring 2 606 is used to squeeze the sliding block 604 into the threaded groove on the threaded rod 2 602. At this time, the threaded rod 2 602 drives the pushing rod 607 at one end of the sliding block 604 to slide toward the end close to the support body 601. The pushing rod 607 moves to push the return spring 2 710 at one end of the pushing ring 708 to contract. When the cleaning sponge 711 is pressed against the outer surface of the seamless steel tube body 14, the cleaning sponge 711 on one side of the pressing base 707 is pressed against the outer surface of the seamless steel tube body 14, thereby assisting in fixing the seamless steel tube body 14, so that the seamless steel tube body 14 remains stable during the size measurement, thereby reducing the measurement error of the device; by setting the rotating cleaning mechanism 7, when the threaded rod 206 rotates to drive the threaded rod 209 to move toward the outer wall of the seamless steel tube body 14, the cleaning sponge 71 ... thereby assisting in fixing the seamless steel tube body 14, When the threaded rod 602 rotates, the threaded rod 602 drives the rotating rod 703 to rotate, the rotation of the rotating rod 703 drives the transmission gear 2 704 to rotate, the rotation of the transmission gear 704 drives the rotating cylinder 701 on the gear ring 702 to rotate, the rotation of the rotating cylinder 701 drives several extrusion bases 707 on the rotating cylinder 701 to rotate, the rotation of the extrusion base 707 drives the cleaning sponge 711 to rub along the outer surface of the seamless steel pipe body 14, such a configuration is conducive to the cleaning sponge 711 to clean the outer surface of the seamless steel pipe body 14, thereby avoiding the influence of impurities on the surface of the seamless steel pipe body 14 on the measurement results.
