Description

Technical Field

[0001] The utility model relates to a machining support tool for a rotary table. Background Art

[0002] As Figure 1 For the rotary table 100 as described above, upper and lower arm plates facing each other are provided at two corners on the front side thereof, namely the upper arm plate 101 and the lower arm plate 102 shown in the figure. A first through hole 1011 needs to be machined on the upper arm plate 101, and a second through hole 1021 needs to be machined on the arm plate two 102. After the machining is completed, the first through hole 1011 and the second through hole 1021 on the same side need to meet certain coaxial requirements, that is, the eccentricity between the upper and lower through holes needs to be controlled within a certain error range.

[0003] Since there is a spacing h between the opposite surfaces of the upper arm plate 101 and the lower arm plate 102, the upper arm plate 101 forms a cantilever structure. Therefore, when machining the first through hole 1011, the upper arm plate 101 will generate certain deformation under the action of the vertical direction, which will affect the machining quality of the through hole and easily cause the eccentricity range between the first through hole 1011 and the second through hole 2021 to exceed the standard. Content of the Utility Model

[0004] The utility model provides a machining support tool for a rotary table, which can be arranged between the upper and lower arm plates of the rotary table to form a reliable support for the upper arm plate of the rotary table. It not only helps to ensure the perpendicularity of the first through hole on the upper arm plate, but also can effectively prevent the eccentricity between the through holes machined on the upper and lower arm plates from exceeding the required range.

[0005] The technical solution adopted by the utility model to solve its technical problems is: a machining support tool for a rotary table, including a base and an annular member.

[0006] The base includes a top plate and a bottom plate arranged oppositely up and down, and a vertical spacing is formed between the opposite end faces of the top plate and the bottom plate. Axial holes are formed on both the top plate and the bottom plate, and the two axial holes are vertically aligned. The inner diameter of the axial hole formed on the bottom plate is not less than the inner diameter of the axial hole formed on the top plate.

[0007] An annular axial flange is formed on the upper end face of the top plate, and the inner diameter of the axial flange is not less than the inner diameter of the axial hole formed on the top plate.

[0008] External threads are formed on the outer peripheral surface of the axial flange. Correspondingly, internal threads are formed on the inner peripheral surface of the annular member. A handle portion extending radially outward is formed on the side wall of the annular member.

[0009] By means of the handle, the annular member can be driven to rotate relative to the axial flange, so as to adjust and control the length of the axial flange screwed into the axial hole of the annular member, achieving the purpose of adjusting the overall height after the base and the annular member are matched, so that the upper arm plate of the rotary table can be supported by the upper end surface of the annular member.

[0010] Optionally, a screw ring is further included. The inner diameter of the axial hole formed on the bottom plate is larger than the inner diameter of the axial hole formed on the top plate, and the upper part of the axial hole formed on the bottom plate is formed as a threaded hole. The screw ring is matched with the threaded hole, so that the upper end surface of the screw ring can move up and down relative to the upper end surface of the bottom plate. The inner diameter of the screw ring is not less than the inner diameter of the axial hole formed on the top plate.

[0011] Optionally, an annular prismatic flange is formed on the lower end surface of the screw ring.

[0012] Optionally, the axial extension length of the axial hole formed on the bottom plate is greater than the axial length of the screw ring.

[0013] Optionally, a handle rod is provided at the free end of the handle on the annular member. The handle rod extends upward in the vertical direction.

[0014] Optionally, a limiting screw rod part is further included, and the limiting screw rod part includes a plurality of limiting screw rods. A plurality of threaded through holes corresponding to and matched with the plurality of limiting screw rods are formed on the base.

[0015] The threaded through holes are distributed on an arc surface in the same circumferential direction.

[0016] The free end of the limiting screw rod can extend into the space formed between the opposite surfaces of the top plate and the bottom plate.

[0017] The beneficial effects of the present utility model are as follows: The support tooling involved in this patent can be arranged between the upper and lower arm plates of the rotary table to form a reliable support for the upper arm plate of the rotary table, which helps to ensure the perpendicularity of the first through hole machined on the upper arm plate, and can effectively prevent the first through hole from being machined into an inclined hole with a large perpendicularity. In addition, with the help of this support tooling, it is allowed to simultaneously machine the first through hole and the second through hole on the same side during the machining process, without the need to reposition, change tools, align tools, etc. steps, which not only improves the efficiency of the machining operation, but also can effectively prevent the eccentricity between the through holes machined on the upper and lower arm plates from exceeding the required range, significantly reducing the rejection rate.

Therefore, they do not have technical essence. Any modification of the structure, change of the proportional relationship or adjustment of the size, without affecting the effects that the present utility model can produce and the purposes that can be achieved, should still fall within the scope covered by the technical content disclosed in the present utility model. At the same time, the terms such as "upper", "lower", "front", "rear", "middle" and the like cited in this specification are only for the convenience of clear narration, and are not used to limit the implementation scope of the present utility model. The change or adjustment of their relative relationships, without substantial change of the technical content, should also be regarded as the implementable scope of the present utility model.

[0024] As Figures 2 to 4 shown, a rotary table processing support tooling includes a base 10, an annular part 20 and a screw ring 30.

[0025] The base 10 includes a top plate 11 and a bottom plate 12 which are arranged oppositely up and down, and a vertical distance H is formed between the opposite end faces of the top plate 11 and the bottom plate 12. The vertical distance H is greater than the thickness h of the lower arm plate 102 on the rotary table 100.

[0026] Axis holes are formed on both the top plate 11 and the bottom plate 12, and the two axis holes are vertically aligned. The inner diameter of the axis hole formed on the bottom plate 12 is greater than the inner diameter of the axis hole formed on the top plate 11. At the same time, a threaded hole 14 is formed in the upper part of the axis hole (which is a stepped through hole structure, and the inner diameter at the lower port of the stepped through hole structure is greater than the inner diameter at its upper port) formed on the bottom plate 12.

[0027] An annular axial flange 13 is formed on the upper end face of the top plate 11, and the inner diameter of the axial flange 13 is the same as the inner diameter of the axis hole formed on the top plate 11, forming a through hole that penetrates axially.

[0028] An external thread is formed on the outer peripheral surface of the axial flange 13. Correspondingly, an internal thread is formed on the inner peripheral surface of the annular member 20. A handle portion extending radially outward is formed on the side wall of the annular member 20. A handle rod 22 is provided at the free end of the handle portion, and the handle rod 11 extends vertically upward.

[0029] By means of the handle portion, the annular member 20 can be driven to rotate relative to the axial flange 13, so as to adjust and control the length of the axial flange 13 screwed into the central hole 21 of the annular member 20, achieving the purpose of adjusting the overall height after the base 10 is matched with the annular member 20, so that the upper arm plate 101 of the rotary table 100 can be supported by the upper end surface of the annular member 20.

[0030] The screw ring 30 is matched with the threaded hole 14, so that the upper end surface of the screw ring 30 can move up and down relative to the upper end surface of the bottom plate 12. The inner diameter of the screw ring 30 is larger than the inner diameter of the shaft hole formed on the top plate 11.

[0031] An annular prismatic flange is formed on the lower end surface of the screw ring 30. The axial extension length of the shaft hole formed on the bottom plate 12 is larger than the axial length of the screw ring 30 (including the prismatic flange part). By rotating the prismatic flange on the screw ring 30, the height position of the upper end surface of the screw ring 30 relative to the upper end surface of the bottom plate 12 can be adjusted, so that the vertical distance between the upper end surface of the screw ring 30 and the lower end surface of the top plate 11 is equivalent to / consistent with the thickness of the lower arm plate 102.

[0032] If the screw ring 30 is not provided, the vertical distance H formed between the opposite end faces of the top plate 11 and the bottom plate 12 should be consistent with the thickness h of the lower arm plate 102 on the rotary table 100, so as to ensure that the lower arm plate 102 can be inserted between the top plate 11 and the bottom plate 12.

[0033] A limit screw portion 15 is provided on the base 10, and the limit screw portion 15 includes a plurality of limit screws. A plurality of threaded through holes corresponding to and matched with the plurality of limit screws are formed on the base 10. The threaded through holes are distributed on an arc surface in the same circumferential direction. The free ends of the limit screws can extend into the distance formed between the opposite faces of the top plate 11 and the bottom plate 12 or the screw ring 30, so that the free end faces of the respective limit screws of the limit screw portion 15 can contact the arc surface at the end of the lower arm plate 102, to limit the depth of the lower arm plate 102 extending into the distance between the lower end surface of the top plate 11 and the upper end surface of the bottom plate 12 (or the screw ring 30), and quickly realize the vertical alignment of the central hole 21 of the annular member 20, the inner hole of the axial flange 13, the shaft hole on the top plate 11, the shaft hole on the bottom plate or the inner hole of the screw ring 30, etc. with the second through hole 1021 on the lower arm plate 102.

[0034] The above embodiments are only illustrative of the principles and effects of the present utility model, rather than limiting the present utility model. There are many aspects of the present utility model that can be improved without departing from the overall idea. Those who are familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present utility model. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present utility model should still be covered by the claims of the present utility model.
