Description
Technical Field
The utility model relates to a spraying technical field, in particular to a strutting arrangement for be used for large-scale sleeve type part.
Background
When the large-scale sleeve type parts are subjected to spraying, repairing and remanufacturing on the surface wear positions, the large-scale sleeve needs to be clamped and rotated, and then a wear-resistant coating is prepared on the surface of the large-scale sleeve by adopting a supersonic flame spraying process. Manufacturers who provide thermal spraying technical services generally do not arrange large lathes in the thermal spraying workshop, so that the large sleeve parts cannot be repaired and remanufactured by adopting the thermal spraying technology. Some manufacturers clamp the workpiece by using a large lathe in a machining workshop, and then repair and remanufacture the workpiece by adopting a thermal spraying technology, but the large lathe is configured in the spraying workshop for realizing thermal spraying, so that the cost is too high, metal dust generated by a thermal spraying process can pollute the environment, and the precision of a lathe guide rail is reduced or even the lathe guide rail is scrapped when the metal dust enters a precision guide rail of the lathe.
SUMMERY OF THE UTILITY MODEL
For solving above-mentioned technical problem, make large-scale sleeve class part rotate under the condition that does not adopt large-scale lathe clamping, the utility model discloses the technical scheme who adopts as follows:
the utility model provides a strutting arrangement for be used for large-scale sleeve type part, it includes rotatable back shaft and installs two sets of at least supporting components on supporting the epaxial, and supporting component includes installation department, a plurality of supporting part and installs the piece of shoring at the supporting part tip, and the installation department suit is on supporting the shaft, and the tip at the supporting part that corresponds is installed through adjustable mode to the piece of shoring.
Furthermore, the support shaft further comprises two supports, and two ends of the support shaft are respectively installed with the two supports through rolling bearings.
Furthermore, the supporting shaft is rotated through a belt transmission mechanism, and the driven wheel is installed on the supporting shaft.
Furthermore, the end part of the top support part is formed with a contact part for supporting the inner wall of the large sleeve part.
Furthermore, the contact part is formed with an arc surface for contacting with the inner wall of the large sleeve part.
Further, each support portion is evenly distributed along the circumferential direction.
Further, the top support piece is installed at the end of the corresponding support part in a threaded connection mode.
Has the advantages that: the supporting component supports the inner wall of the large-scale sleeve part through the supporting pieces, the supporting shaft drives the large-scale sleeve part to rotate, the clamping mode of a large-scale lathe is replaced, and cost is saved. The utility model discloses it is rational in infrastructure, but wide application in spraying technical field.

Detailed Description
The present invention will be further described with reference to fig. 1 to 3.
The utility model relates to a strutting arrangement for large-scale sleeve type part, large-scale sleeve type part for example marine large-scale cylinder liner, strutting arrangement include rotatable back shaft 11 and install two sets of at least supporting components on back shaft 11, and back shaft 11 passes large-scale sleeve type part, and supporting components is used for supporting the inner wall of large-scale sleeve type part to realize the steady rotation of large-scale sleeve type part easily through back shaft 11. For example: the number of the supporting assemblies is three, and the distance between two adjacent groups of supporting assemblies is the same; or the number of the supporting components is two, and the positions of the two groups of supporting components are respectively close to the two ends of the large-scale sleeve part.
The supporting device further comprises two supports, and two ends of the supporting shaft 11 are respectively installed with the two supports through rolling bearings.
The support shaft 11 is rotated through a belt transmission mechanism, the driven wheel 15 is installed on the support shaft 11, the belt transmission mechanism comprises a motor 17 and a transmission belt 18, and a driving wheel is arranged at the output end of the motor 17. The belt transmission mechanism can be replaced by one of a chain transmission mechanism, a gear transmission mechanism and a worm and gear transmission mechanism, or the transmission is realized by adopting a mode of installing the supporting shaft 11 and a motor output shaft.
The supporting component comprises an installation part 12, a plurality of supporting parts 13 and a top support part 14 installed at the end part of the supporting part 13, the installation part 12 is sleeved on the supporting shaft 11, each supporting part 13 is arranged on the outer side of the installation part 12, and the top support part 14 supports against the inner wall of a large sleeve part. The top support 14 and the corresponding support portion 13 constitute a support arm, and the top support 14 is mounted at the end of the corresponding support portion 13 in an adjustable manner, where the length of the support arm is adjusted.
The support portions 13 are uniformly distributed in the circumferential direction, for example: the number of the supporting parts 13 is four, and an included angle between two adjacent supporting parts 13 is a right angle, which can be regarded as the first embodiment of the supporting device; the number of the supporting portions 13 is three, and the included angle between two adjacent supporting portions 13 is 120 °, which can be regarded as the second embodiment of the supporting device.
The top supporting pieces 14 are installed at the end portions of the corresponding supporting portions 13 in a threaded connection mode, the top supporting pieces 14 are adjusted through threads, the large-scale sleeve parts are supported and fixed by the top supporting pieces 14, the supporting shaft 11 is aligned with the large-scale sleeve parts, and the supporting shaft 11 drives the large-scale sleeve parts to rotate synchronously.
