Description

Technical Field

[0001] The present application relates to the technical field of guide column processing equipment, and in particular to a positioning fixture for processing an inclined guide column. Background Art

[0002] Our company currently processes and produces a kind of inclined guide column, which needs to be drilled with a threaded hole or a positioning hole for installation. The central axis of the threaded hole or the positioning hole is relatively inclined relative to the central axis of the inclined guide column, so that the inclined guide column is inclined after installation and fixation.

[0003] At present, the drilling machines used for processing are generally straight up and straight down, so it is necessary to deflect the inclined guide column so that when the drilling machine drills straight up and straight down, the drilled hole can be tilted relative to the inclined guide column. The positioning fixture currently used for deflecting the inclined guide column, such as the Chinese patent with announcement number CN206216537U, discloses a processing fixture, and particularly relates to a processing fixture for inclined guide column holes. It includes two fixed plates and a workpiece that are spaced apart, the lower ends of the fixed plates are positioned by low-end positioning pins, and the high ends of the fixed plates are provided with a plurality of angle adjustment holes, and high-end positioning pins are provided between the angle adjustment holes.

[0004] With respect to the above-mentioned related technologies, the inventors found that when positioning and adjusting are performed by means of positioning pins, the adjustable angle is fixed, which results in the inability to meet the positioning requirements of the inclined guide columns with partial tilt angles. Utility Model Content

[0005] In order to solve the above technical problems, the present application provides an inclined guide column processing positioning jig, which has the advantage of being able to achieve stepless adjustment of the inclination angle of the inclined guide column to meet the positioning requirements of the inclined guide column.

[0006] In order to achieve the above object, the technical solution of the utility model is as follows:

[0007] A positioning fixture for processing an inclined guide column, comprising a base plate, a positioning plate hinged on the base plate, an abutment groove for abutting the inclined guide column on the positioning plate, and a rotation driving member for driving the positioning plate to rotate on the base plate;

[0008] The rotating driving member comprises a driving block and a servo electric cylinder for driving the driving block to move back and forth in the direction of the rotating axis of the positioning plate, and the bottom of the positioning plate abuts against the driving block.

[0009] The above technical solution is implemented, that is, the positioning plate is driven to rotate by the rotating driving member, so that the inclination angle of the bottom plate of the abutment groove changes, so that after the inclined guide column is placed in the abutment groove, the inclined guide column follows the abutment groove to deflect, thereby meeting the needs of drilling holes with different inclination angles, and because the abutment groove directly follows the rotation of the positioning plate, its inclination angle can be adjusted steplessly at a certain angle following the positioning plate, thereby meeting different positioning requirements of the inclined guide column; when the servo electric cylinder drives the driving block to gradually insert between the positioning plate and the base plate, it will lift the positioning plate, thereby driving the positioning plate to rotate, thereby achieving the effect of adjusting the inclination angle to meet the processing requirements, and at the same time, the positioning plate is supported by the driving block and the hinge shaft to ensure the stability of the positioning plate during drilling; and the telescopic length of the servo motor is controllable.

[0010] As a preferred solution of the present application, the bottom wall of the abutment groove is inclined.

[0011] By implementing the above technical solution, when the positioning plate is in a horizontal state, the bottom wall of the abutment groove is still inclined, so that when the inclined guide column is placed in the abutment groove, the plane direction is restricted and will not deviate, thereby ensuring the processing accuracy.

[0012] As a preferred solution of the present application, an avoidance groove is provided at the connection between the bottom wall and the side wall of the abutment groove.

[0013] The above technical solution is implemented to prevent the edge of the bottom wall of the inclined guide column from hitting the bottom wall of the abutment groove and causing damage.

[0014] As a preferred solution of the present application, a slide plate is hinged on the driving block, and a slide groove for sliding the slide plate is arranged at the bottom of the positioning plate.

[0015] The above technical solution is implemented to reduce the point-line contact pressure wear between the positioning plate and the driving block, thereby ensuring the accuracy of the positioning plate angle control and thus ensuring the service life.

[0016] As a preferred solution of the present application, a bearing plate is arranged on the substrates on both sides of the positioning plate, and a supporting plate which is arranged in contact with the bearing plate is arranged on the positioning plate.

[0017] The above technical solution is implemented to prevent the telescopic rod connecting the servo electric cylinder and the driving block from bending due to the force applied to the driving block and thus being unable to normally extend and retract.

[0018] In summary, the present application includes at least one of the following beneficial technical effects:

[0019] 1. That is, the positioning plate is driven to rotate by the rotating driving member, so that the inclination angle of the bottom plate of the abutment groove changes, so that after the inclined guide column is placed in the abutment groove, the inclined guide column follows the abutment groove to deflect, thereby meeting the needs of drilling holes at different inclination angles, and because the abutment groove directly follows the rotation of the positioning plate, its inclination angle can be adjusted steplessly at a certain angle following the positioning plate, thereby meeting the different positioning needs of the inclined guide column; when the servo electric cylinder drives the driving block to gradually insert between the positioning plate and the base plate, it will lift the positioning plate, thereby driving the positioning plate to rotate, thereby achieving the effect of adjusting the inclination angle to meet the processing needs, and at the same time, the positioning plate is supported by the driving block and the hinge shaft to ensure the stability of the positioning plate during drilling; and the telescopic length of the servo motor is controllable.

[0025] The following is combined with Figure 1-3 This application is described in further detail.

[0026] The present application embodiment discloses a positioning fixture for processing an inclined guide column. Figure 1The oblique guide column processing positioning fixture includes a base plate 1, a positioning plate 2 is hinged on the base plate 1, an abutment groove 3 for the oblique guide column to abut is provided on the positioning plate 2, and a rotating driving member for driving the positioning plate 2 to rotate is provided on the base plate 1. That is, the positioning plate 2 is driven to rotate by the rotating driving member, so that the inclination angle of the bottom plate of the abutment groove 3 changes, so that after the oblique guide column is placed in the abutment groove 3, the oblique guide column follows the abutment groove 3 to deflect, thereby meeting the needs of drilling holes at different inclination angles, and because the abutment groove 3 directly follows the rotation of the positioning plate 2, its inclination angle can follow the positioning plate 2 to be adjusted steplessly at a certain angle, thereby meeting different positioning needs of the oblique guide column.

[0027] The bottom wall of the abutment groove 3 is tilted, so that when the positioning plate 2 is in a horizontal state, the bottom wall of the abutment groove 3 is still tilted, so that when the inclined guide column is placed in the abutment groove 3, the plane direction is restricted and will not be offset, thereby ensuring the processing accuracy.

[0028] An avoidance groove is provided at the connection between the bottom wall and the side wall of the abutment groove 3 to prevent the edge of the bottom wall of the inclined guide column from hitting the bottom wall of the abutment groove 3 and causing damage.

[0029] The rotating drive member includes a driving block 4 and a servo electric cylinder 5 for driving the driving block 4 to move back and forth in the direction of the rotation axis of the positioning plate 2. The bottom of the positioning plate 2 abuts against the driving block 4. As a result, when the servo electric cylinder 5 drives the driving block 4 to gradually insert between the positioning plate 2 and the base plate 1, it will lift up the positioning plate 2, thereby driving the positioning plate 2 to rotate, thereby achieving the effect of adjusting the tilt angle to meet the processing requirements. At the same time, the positioning plate 2 is supported by the driving block 4 and the hinge shaft to ensure the stability of the positioning plate 2 when drilling. And the telescopic length of the servo motor is controllable.

[0030] A slide plate 6 is hinged on the driving block 4, and a slide groove 7 for the slide plate 6 to slide is provided at the bottom of the positioning plate 2 to reduce the point-line contact pressure wear between the positioning plate 2 and the driving block 4, thereby ensuring the accuracy of the angle control of the positioning plate 2 and thus ensuring the service life.

[0031] A bearing plate 9 is arranged on the substrates on both sides of the positioning plate, and a support plate 8 is arranged on the positioning plate to fit the bearing plate 9 to prevent the telescopic rod connecting the telescopic electric cylinder and the driving block 4 from bending due to the force on the driving block 4 and being unable to retract normally.

[0032] The implementation principle of the inclined guide column processing positioning fixture of the embodiment of the present application is: that is, the positioning plate 2 is driven to rotate by a rotating driving member, so that the inclination angle of the bottom plate of the abutment groove 3 changes, so that after the inclined guide column is placed in the abutment groove 3, the inclined guide column follows the abutment groove 3 to deflect, thereby meeting the requirements of drilling holes at different inclination angles, and because the abutment groove 3 directly follows the rotation of the positioning plate 2, its inclination angle can be adjusted steplessly at a certain angle following the positioning plate 2, thereby meeting different positioning requirements of the inclined guide column; when the servo electric cylinder 5 drives the driving block 4 to gradually insert between the positioning plate 2 and the base plate 1, it will lift the positioning plate 2, thereby driving the positioning plate 2 to rotate, thereby achieving the effect of adjusting the inclination angle to meet the processing requirements, and at the same time, the positioning plate 2 is supported by the driving block 4 and the hinge shaft to ensure the stability of the positioning plate 2 during drilling; and the telescopic length of the servo motor is controllable.

[0033] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
