Description
Technical Field
The invention belongs to the technical field of motor base bearing seat detection tools, and particularly relates to an elastic rod detection tool for detecting a bearing seat motor seat.
Background
In the installation and debugging process of equipment such as a numerical control lathe, a vertical machining center and the like, the coaxiality of an X \ Y \ Z-axis motor base and a bearing hole of a bearing seat needs to be aligned. The special inspection rods are respectively inserted into the motor base and the bearing seat in the assembly field, the central axis of the bearing hole is reflected to the inspection rods, the dial indicator is placed on the guide rail sliding block, the two inspection rods are aligned to be coaxial, and the alignment of the coaxiality of the motor base and the bearing seat bearing hole is realized.
However, this approach also has certain problems. Taking the bearing hole base size of 62 as an example, IT6 tolerance (0, + 0.019). In order to better derive the axis of the bearing hole of the motor seat and the bearing seat, the fit clearance between the detection rod and the bearing hole is 0.001mm to 0.002mm. There are two ways at the assembly site: 1. processing a motor base and a bearing seat part door to process the sizes of bearing holes to be consistent (the consistency of the hole sizes is within 0.003 mm), and matching a detection rod; 2. and (4) making three detection rods, namely uniformly taking three sizes in the IT 6-level tolerance zone range, and selecting proper detection rods according to the actual sizes of different workpieces.
The former method is highly demanding on the manufacturing side (high machine accuracy, good worker skill) and high manufacturing costs, and the latter method is more common at the assembly site. However, in the latter method, three test rods are required for each specification order, and fifteen test rods need to be ordered for the motor base or the bearing seat if five teams are assembled on site at the same time. Therefore, a great number of detection rods are needed for bearing seats and motor bases of different specifications and sizes of the whole series of numerical control machine tools. Resulting in increased picking tool management costs and fixture manufacturing costs. And if the contact part of the detection rod and the bearing hole is worn, the detection rod is wasted.
Disclosure of Invention
The invention designs an elastic detection rod according to the characteristic that the diameter of a part is adjusted within a tolerance range as required, and the diameter of the detection rod can be changed according to the actual size of an inner hole of the part, so that the detection rod and a bearing seat or a motor base are integrated. If the expansion sleeve at the contact part of the elastic detection rod and the bearing hole is abraded, the elastic detection rod can be continuously used only by replacing a new expansion sleeve, and the service life of the elastic detection rod is prolonged.
The invention adopts the following technical scheme: an elastic rod detection tool for detecting a bearing seat motor base is characterized in that a hollow expansion sleeve is arranged in a bearing hole of a bearing seat, a mandrel rod detection is arranged in the expansion sleeve, and the other end of the expansion sleeve is connected with a connecting sleeve; the connecting sleeve is connected with the pushing sleeve, and the pushing sleeve is fixedly connected with the pushing hoop; the mandrel detection rod sequentially passes through the connecting sleeve, the pushing sleeve and the pushing hoop; the push collar moves along the threads on the mandrel check rod.
Preferably, in the elastic rod detecting tool for detecting the bearing seat motor base, the expansion sleeve is fixedly connected with the connecting sleeve through a bolt.
Preferably, in the elastic rod detection tool for detecting the motor base of the bearing seat, the pushing sleeve is connected with the connecting sleeve through the groove and the flange, and the width of the groove of the pushing sleeve is larger than the thickness of the flange of the connecting sleeve.
Preferably, in the elastic rod detection tool for detecting the motor base of the bearing seat, the pushing sleeve is connected with the pushing hoop through a bolt.
Preferably, in the elastic rod detecting tool for detecting the bearing seat motor base, the expansion sleeve (5) is made of spring steel.
In the using process, the mandrel detection rod is firstly placed into the bearing hole, and the shaft shoulder end face of the mandrel detection rod is attached to the inner end face of the bearing hole. The expansion sleeve is attached to the 10-degree inclined plane of the mandrel detection rod, and the thickness of the expansion part of the expansion sleeve is required to be equal to 0.001mm. The push hoop is rotated to push the expansion sleeve to expand along the 10-degree inclined plane of the mandrel detection rod, and finally the expansion sleeve is completely attached to the bearing hole, so that the mandrel detection rod, the bearing seat and the motor base are integrated.
The invention is suitable for aligning the inspection rod required by the mutual coaxiality of the motor seat and the bearing hole of the bearing seat in the assembling process of equipment such as a numerical control lathe, a vertical machining center and the like.
The invention has the beneficial effects that:
1. the invention makes the expansion sleeve expand uniformly on the mandrel detection rod, and the expansion sleeve has expansion amount, so the diameter of the elastic detection rod can change according to the size change of the bearing hole, and the detection rod is completely jointed with the bearing hole.
2. The invention can reduce the number of the check rods needed to be stored in the tool room, is convenient to manage, and can reduce the purchasing cost of the check rods. If the expansion sleeve of the elastic detection rod is worn, only a new expansion sleeve needs to be replaced, and compared with the original detection rod, the elastic detection rod has longer service life.
