Description

Technical Field

[0001] The present invention belongs to the technical field of processing auxiliary equipment, and particularly relates to an economic coaxiality detection and adjustment device for deep hole machining tooling. Background Art

[0002] In machining, after long-term use of the machining equipment, due to reasons such as equipment vibration, tooling deformation, and displacement, it is easy to cause the offset and non-coaxiality between the machining spindle axis and the clamping central axis of the tooling fixture, and the non-perpendicularity between the machining spindle axis and the vertical plane of the tooling, resulting in problems such as machining deviation, reduced accuracy, tooling and equipment damage, and in severe cases, it may cause the burnout of the spindle motor of the equipment. Moreover, due to machining errors in the bed spindle mounting holes and columns, it is difficult to detect with a dial indicator during equipment and tooling debugging, and it often relies on the experience of workers or multiple trial machinings for calibration, which poses potential risks to both the equipment and the tooling, and cannot ensure that the spindle axis of the machine tool completely coincides with the axis of the workpiece. As a result, after drilling, the deviation between the axis of the hole and the axis of the workpiece is large, and the requirements of the drawing cannot be met. Summary of the Invention

[0003] The purpose of the present invention is to provide an economic coaxiality detection and adjustment device for deep hole machining tooling in view of the above problems.

[0004] To achieve the above object, the present invention adopts the following technical solutions: An economic coaxiality detection and adjustment device for deep hole machining tooling includes a positioning block movably arranged on a square box base and located outside one end of the workpiece. The positioning block is connected with a clamping drive mechanism capable of driving the positioning block to vertically lift along the square box base. A thimble seat is provided at one end of the positioning block close to the workpiece. One end of the thimble seat close to the workpiece is movably connected with an adjustable thimble, and a multi-axis adjustment structure capable of adjusting the coaxiality between the adjustable thimble and the workpiece is provided between the adjustable thimble and the thimble seat. A multi-axis displacement display structure is provided on the circumferential outer side of the adjustable thimble. The lower end of the workpiece is fixed below the square box base, and the positioning block moves towards the upper end of the workpiece through the clamping drive mechanism. When the thimble seat on the positioning block approaches the upper end of the workpiece, it stops. At the same time, the adjustable thimble at the lower end of the thimble seat abuts against the upper end of the workpiece. Then, the multi-axis displacement display structure on the circumferential outer side of the adjustable thimble is checked, and then the multi-axis adjustment structure is adjusted to correct the coaxiality between the spindle axis and the workpiece axis.

[0005] In the above-described coaxiality detection and adjustment device for an economical deep-hole machining tooling, the positioning block is located directly above the workpiece, the upper end of the thimble seat penetrates through the mounting hole at the lower end of the positioning block, and the thimble seat is connected to the positioning block through a detachable connection assembly. The adjustable thimble is movably arranged at the lower end of the thimble seat and corresponds to the upper end of the workpiece. The upper end of the thimble seat is inserted into the mounting hole of the positioning block, ensuring the same coaxiality between the positioning block and the thimble seat, avoiding excessive deviation, and the thimble seat further improves the stability by using the detachable connection assembly.

[0006] In the above-described coaxiality detection and adjustment device for an economical deep-hole machining tooling, the detachable connection assembly includes a thimble seat fixing ring arranged on the circumferential outer side of the thimble seat. The upper end of the thimble seat fixing ring abuts against the lower end of the positioning block, and there are a number of fixing holes in the circumferential direction of the thimble seat fixing ring. The fixing holes are connected to the positioning holes at the lower end of the positioning block through fixing bolts. The thimble seat is connected to the lower end of the positioning block through the thimble seat fixing ring on the outside, increasing the contact area and improving the fixing property.

[0007] In the above-described coaxiality detection and adjustment device for an economical deep-hole machining tooling, the multi-axis adjustment structure includes a thimble adjustment part formed at the upper end of the adjustable thimble. The lower end of the thimble adjustment part is coaxially connected to a thimble part with a thimble groove corresponding to the upper end of the workpiece at the lower end. The thimble adjustment part is inserted into the adjustment hole at the lower end of the thimble seat, and a multi-axis adjustment assembly is arranged between the thimble adjustment part and the thimble seat. The adjustable thimble is arranged at the lower end of the thimble seat through the thimble adjustment part. The upper end of the workpiece abuts against the thimble groove at the lower end of the adjustable thimble. The thimble seat is fixedly connected to the positioning block, so the coaxiality of the adjustable thimble can be adjusted through the thimble seat.

[0008] In the above-described coaxiality detection and adjustment device for an economical deep-hole machining tooling, the multi-axis adjustment assembly includes an X-axis adjustment assembly and a Y-axis adjustment assembly. The diameter of the adjustment hole is larger than the diameter of the thimble adjustment part, and an annular adjustment gap is formed between the inner side of the circumferential direction of the adjustment hole and the outer side of the circumferential direction of the thimble adjustment part. The X-axis adjustment assembly and the Y-axis adjustment assembly respectively extend into the annular adjustment gap and act on the outer side of the circumferential direction of the thimble adjustment part. The X-axis adjustment assembly and the Y-axis adjustment assembly are adjusted through the annular adjustment gap, thereby realizing the correction of the deviation amount between the adjustable thimble and the workpiece, and at the same time solving the problem that the spindle axis does not coincide with the workpiece axis.

[0009] In the above-mentioned coaxiality detection and adjustment device for an economical deep-hole machining tooling, the X-axis adjustment assembly and the Y-axis adjustment assembly are arranged perpendicular to each other, and the X-axis adjustment assembly and the Y-axis adjustment assembly respectively include at least one set of bolt adjustment assemblies. Each bolt adjustment assembly includes at least one adjustable bolt threadedly connected to the outside of the thimble seat. The adjustable bolt radially penetrates the thimble seat and abuts against the circumferential outside of the thimble adjustment part. At least one locknut is also provided on the circumferential outside of the thimble seat. The locknut is internally threaded with a lock bolt radially passing through the thimble seat, and one end of the lock bolt radially inserts into the outside of the thimble adjustment part and is threadedly connected to the thimble adjustment part. The adjustable thimble is adjusted for deviation through the adjustable bolt and then fixed by the locknut and the lock bolt, which is simple and convenient and has high practicability.

[0010] In the above-mentioned coaxiality detection and adjustment device for an economical deep-hole machining tooling, the circumferential outside of the thimble adjustment part has four uniformly arranged planes, and the adjustable bolts respectively abut against the planes. Bolt connection holes connected to the lock bolts are also provided on the planes. The thimble adjustment part adopts a structure with planes around it to form the above-mentioned annular adjustment gap, which is beneficial to the use of the adjustable bolts and avoids the phenomenon of slipping and loosening.

[0011] In the above-mentioned coaxiality detection and adjustment device for an economical deep-hole machining tooling, the multi-axis displacement display structure includes a gauge base fixing frame coaxially sleeved on the circumferential outside of the thimble part. The upper end of the gauge base fixing frame has a fixing frame connection ring sleeved on the circumferential outside of the thimble seat, and a number of fixing frame anti-loosening holes for installing anti-loosening bolts are provided on the fixing frame connection ring. An X-axis displacement display component and a Y-axis displacement display component are provided on the gauge base fixing frame. The X-axis displacement display component and the X-axis adjustment assembly are arranged in the same direction, and the Y-axis displacement display component and the Y-axis adjustment assembly are arranged in the same direction. The X-axis displacement display component and the Y-axis displacement display component both include at least one digital display displacement micrometer. The contact part of the digital display displacement micrometer passes through the gauge base fixing frame and abuts against the circumferential outside of the thimble part. By installing the gauge base fixing frame on the circumferential outside of the thimble part and simultaneously using the X-axis displacement display component and the Y-axis displacement display component, two digital display displacement micrometers are added, which intuitively expresses the deviation amount that needs to be corrected and helps the debugging personnel to quickly correct.
