Description

Technical Field

[0001] The present application relates to the field of machine tool accessories, and in particular to an adjustable crankshaft lathe cyclone tool holder rod checking bracket. Background Art

[0002] The neck of the crankshaft of a large marine low-speed diesel engine is processed using a cyclone tool holder on a crankshaft lathe. The machining accuracy of the crankshaft neck is very high, with both roundness and straightness requirements, so the geometric accuracy of the cyclone tool holder itself is also very high. The cyclone tool holder should often use a check rod to detect its geometric accuracy and make adjustments. The check rod is hoisted to the bracket of the lathe center frame using a crane, and then the posture of the check rod is adjusted. Correspondingly, it is also necessary to install measuring instruments such as a micrometer on the cyclone tool holder. The micrometer is in contact with the check rod, and then the cyclone tool holder is started. The staff debugs the cyclone tool holder based on the feedback of the micrometer, etc.

[0003] With regard to the above-mentioned related technologies, the rod inspection needs to be parallel to the track of the lathe when in use. It is difficult to conveniently adjust the rod inspection posture with the existing mounting bracket or related accessories, and frequent lifting and adjustment by an overhead crane is required. Utility Model Content

[0004] In order to conveniently adjust the posture of the inspection rod so that the inspection rod is parallel to the lathe track, the present application provides an adjustable crankshaft lathe cyclone tool holder inspection rod bracket.

[0005] The present application provides an adjustable crankshaft lathe cyclone tool holder rod inspection bracket adopts the following technical solution:

[0006] An adjustable crankshaft lathe cyclone tool holder rod inspection bracket, comprising a base for connecting to a center frame, the base being fixedly connected to a vertical plate, the vertical plate being provided with an open placement groove at one end away from the center frame, the vertical plate being provided with two horizontal adjustment bolts and one vertical adjustment bolt, the two horizontal adjustment bolts being arranged opposite to each other, the horizontal adjustment bolt and the vertical adjustment bolt being jointly abutted against and supporting the inspection rod;

[0007] The vertical adjustment bolt is provided with a supporting portion and a force applying portion, wherein the supporting portion is located at the upper portion of the vertical adjustment bolt and is used to abut against the inspection rod, and the force applying portion is located at the screw position of the vertical adjustment bolt.

[0008] By adopting the above scheme, the base is first installed on the middle frame, the inspection rod is hoisted to the placement slot position of the vertical plate, the inspection rod is slowly lowered, and the posture of the inspection rod is adjusted by the horizontal adjustment bolt and the vertical adjustment bolt until the inspection rod is parallel to the track of the lathe. The supporting part increases the size of the top of the vertical adjustment bolt, improves the stability of the inspection rod placement, and reduces the probability of the inspection rod being skewed; the force-applying part makes it easy for the staff to use tools such as wrenches to adjust the vertical adjustment bolts, thereby improving the convenience of equipment debugging.

[0009] Preferably, the vertical plate is fixed with reinforcing ribs, and the reinforcing ribs are connected to the base.

[0010] By adopting the above solution, the reinforcing ribs enhance the connection strength between the vertical plate and the base, thereby improving the overall stability of the bracket.

[0011] Preferably, the vertical plate is provided with a reinforcement portion, and the reinforcement portion is located on a side of the placement slot away from the intermediate frame.

[0012] By adopting the above solution, the reinforcement part enhances the bearing capacity of the vertical plate at the position corresponding to the placement groove, thereby reducing the probability of deformation and cracking of the placement groove under the weight of the inspection rod.

[0013] Preferably, the base is provided with a mounting bolt, and a gasket is provided between the mounting bolt and the base.

[0014] By adopting the above solution, the base is quickly installed on the center frame by means of mounting bolts, which makes it easy for workers to quickly disassemble the bracket. The gasket improves the tightening capacity of the mounting bolts and reduces the probability of loosening of the mounting bolts.

[0015] Preferably, a positioning block is fixedly connected to one side of the base close to the center frame, and a positioning groove is provided on the center frame at a position corresponding to the positioning block.

[0016] By adopting the above solution, since the base is connected to the center frame by mounting bolts, the mounting bolts pass through the base and are threadedly connected to the center frame, and the through hole of the base corresponding to the mounting bolts is usually larger than the diameter of the mounting bolts. During the tightening process of the mounting bolts or when the mounting bolts are loose, the base is prone to slide, reducing the installation accuracy and stability of the bracket. Therefore, the positioning block is plugged into the positioning groove to limit the sliding of the base relative to the center frame, thereby improving the stability of the base installation.

[0017] Preferably, the vertical adjustment bolt sleeve is provided with an auxiliary spring, and the auxiliary spring applies a force to the vertical adjustment bolt vertically toward the axis of the inspection rod.

[0018] By adopting the above scheme, the auxiliary spring shares the axial force and radial force on the vertical adjusting bolt, which will reduce the probability of the vertical adjusting bolt being bent by the inspection rod during the lifting process, thereby improving the accuracy of equipment adjustment and extending its service life.

[0019] Preferably, a plurality of reference points are arranged at positions of the vertical plate corresponding to the placement grooves, and all of the reference points are arranged around the vertical adjustment bolts.

[0020] By adopting the above solution, before placing the inspection rod, the staff observes the positional relationship between the bolt head and the reference point along the axial direction of the vertical adjustment bolt. If the vertical adjustment bolt is not concentric with the reference point of the array, it means that the vertical adjustment bolt is skewed.

[0021] In summary, this application has the following beneficial effects:

[0022] 1. Adjust the posture of the inspection rod through the horizontal adjustment bolt and the vertical adjustment bolt until the inspection rod is parallel to the track of the lathe. The force-applying part is convenient for the staff to use tools such as wrenches to adjust the vertical adjustment bolts, thereby improving the convenience of equipment debugging;

[0023] 2. The reinforcement part enhances the bearing capacity of the vertical plate at the position corresponding to the placement slot, reducing the probability of deformation and cracking of the placement slot under the weight of the inspection rod;

[0024] 3. The base is quickly installed on the center frame by means of mounting bolts, which makes it easy for workers to quickly disassemble the bracket. The gasket improves the tightening capacity of the mounting bolts and reduces the probability of loosening of the mounting bolts. BRIEF DESCRIPTION OF THE DRAWINGS
