Abstract
The utility model relates to the rim machining and producing technology field, and provides a high-precision rim screw hole-machining frock clamp. A backer (6) and a base (4) are fixed on a workbench (7). A shaft hole of a rim (3) is sleeved onto the base (4). An upper positioning sleeve (2) is sleeved on the base (4) and in the shaft hole of the rim (3). An elastic rubber pad (5) is fixed on the backer (6). Two edges of the rim (3) are placed on the elastic rubber pad (5). A screw (1) presses the upper positioning sleeve (2), and is threadedly connected and fixed on the base (4). The high-precision rim screw hole-machining frock clamp eliminates up-down movement of the rim during the product processing process, increasing the precision of screw holes after the boring. Meanwhile, the contact area between the rim and the base is large, facilitating improvement of the screw hole machining precision.
Description
Technical field:
The utility model relates to the wheel rim production technical field, used frock clamp during more specifically to a kind of wheel rim processing.
Background technology:
As shown in Figure 1, existing wheel rim need be fixed tightly in wheel rim on the frock clamp and process when processing screw hole; Existing frock clamp is made up of backer A1, base A2, clamping bar A3, last positioning sleeve A4; Backer A1 is fixed on the workbench A5, is fixed with clamp mechanism on the backer A1, two limits that wheel rim in the clamping bar A3 difference clamping of clamp mechanism; The axis hole sleeve of wheel rim A6 is on base A2, and last positioning sleeve A4 sleeve is on base A2 and in the axis hole top of wheel rim A6.Its weak point is: 1, two limits of wheel rim directly contact with the backer, in process, to the wheel rim processing screw hole, certainly will cause the vibration of workbench, and wheel rim is subject to the vibration of workbench and beats, the precision of the screw that influence processes.2, base and wheel rim sleeve on base and the wheel rim contact-making surface, are unfavorable for centralized positioning together, also influence machining accuracy.
The utility model content:
The purpose of the utility model is exactly the deficiency to prior art; And a kind of high accuracy wheel rim screw machining tool fixture is provided; It has eliminated beating of wheel rim in the product processing; Improved the precision of boring rear bolt hole, wheel rim and base contact area are big simultaneously, also are beneficial to and improve the screw machining accuracy.
The technological solution of the utility model is following:
High accuracy wheel rim screw machining tool fixture; Comprise workbench, backer, base, go up positioning sleeve and wheel rim, backer and base are fixed on the workbench, and the axis hole sleeve of wheel rim is on base; Last positioning sleeve sleeve is on base and in the axis hole of wheel rim; The last resilient rubbber cushion that is fixed with of backer, two limits of wheel rim place on the resilient rubbber cushion, and screw rod is being pressed to go up positioning sleeve and be spirally connected and is being fixed on the base.
Form the plane on the said base, the axis hole lower surface compacting of wheel rim in the plane.
The beneficial effect of the utility model is:
1, after wheel rim was contained on the base, suppressed in the plane the axis hole lower surface of wheel rim, utilizes screw rod to fix, behind the assurance wheel rim location, and the axis coinciding of wheel rim axial line and drill center working head; Compared with prior art, the whole plane contact with base in the utility model wheel rim axis hole lower surface, the location degree is good.
2, wheel rim does not directly contact with the backer, beat to the influence of product orientation precision to prevent wheel rim, and the flexible rubber blanket of pad one deck band on the backer, the supplemental support product plays cushioning effect.Compare with routine processing, it has been eliminated the product wheel rim and has beated, and the influence to boring rear bolt hole position degree has improved machining accuracy.
Description of drawings:
Fig. 1 is the prior art constructions sketch map
Fig. 2 is the structural representation of the utility model
Among Fig. 2: 1, screw rod; 2, go up positioning sleeve; 3, wheel rim; 4, base; 5, resilient rubbber cushion; 6, backer; 7, workbench; 41, plane.
The specific embodiment:
Embodiment: see shown in Figure 2ly, high accuracy wheel rim screw machining tool fixture comprises workbench 7, backer 6, base 4, goes up positioning sleeve 2 and wheel rim 3; Backer 6 is fixed on the workbench 7 with base 4; The axis hole sleeve of wheel rim 3 is on base 4, and last positioning sleeve 2 sleeves are fixed with resilient rubbber cushion 5 on base 4 and in the axis hole of wheel rim 3 on the backer 6; Two limits of wheel rim 3 place on the resilient rubbber cushion 5, and screw rod 1 is being pressed to go up positioning sleeve 2 and be spirally connected and is being fixed on the base 4.
Operation principle: through screw rod 1 wheel rim 3 is fixed tightly on the base, on backer 6, adds resilient rubbber cushion 5, the supplemental support product plays cushioning effect, can eliminate the product wheel rim like this and beat, and the influence to boring rear bolt hole position degree has improved machining accuracy.
Contact with plane 41 on the base 4 through the axis hole lower surface of wheel rim 3, improve the registration of axis of axis and the wheel rim 3 of drill center working head, help improving machining accuracy.
Claims (2)
1. high accuracy wheel rim screw machining tool fixture; Comprise workbench (7), backer (6), base (4), go up positioning sleeve (2) and wheel rim (3); Backer (6) and base (4) are fixed on the workbench (7); The axis hole sleeve of wheel rim (3) is on base (4), and last positioning sleeve (2) sleeve is characterized in that: be fixed with resilient rubbber cushion (5) on the backer (6) on base (4) and in the axis hole of wheel rim (3); Two limits of wheel rim (3) place on the resilient rubbber cushion (5), and screw rod (1) is being pressed to go up positioning sleeve (2) and be spirally connected and is being fixed on the base (4).
