Detailed Description
The following describes the embodiments of the present invention further with reference to the drawings.
Fig. 1 and 2 show a mounting plate 1, a support pin 2, a spring 3, a work holder mounting plate 4, a centering plate 5, a connecting plate 6, a ball float shaft 7, a support pin 8, a spring 9, a spring seat 10, a support pin mounting plate 11, a spacer 12, and the like.
As shown in fig. 1 and 2, the invention relates to a variable cylinder reaming and honing hole floating tool, which comprises an installation plate 1, wherein a support pin installation plate 11 is vertically arranged on the upper surface of the installation plate 1, a first support pin 8 which can elastically stretch and retract is arranged on the support pin installation plate 11 in a penetrating manner, and a centering plate 5 is also fixed on the upper surface of the installation plate 1; a workpiece clamp mounting bottom plate 4 is arranged above the mounting plate 1 in parallel, a connecting plate 6 is fixed on the bottom surface of the workpiece clamp mounting bottom plate 4, and the working end of a first supporting pin 8 elastically abuts against the side surface of the connecting plate 6; the ball head floating shaft 7 is fixed at the middle part of the bottom surface of the connecting plate 6, the centering plate 5 is matched and arranged on the ball head floating shaft 7, the centering plate 5 is movably matched and connected with the ball head floating shaft 7, and the top angles of the connecting plate 6 are respectively provided with the elastically telescopic second supporting pins 2.
One side of the first supporting pin 8 corresponding to the supporting pin mounting plate 11 is limited by a gasket 12 and a nut, a spring seat 10 and a first spring 9 are sleeved on the other side of the first supporting pin 8 corresponding to the supporting pin mounting plate 11, one end of the first spring 9 is propped against a baffle plate formed on the first supporting pin 8, and the other end of the first spring 9 is propped against the spring seat 10. In specific use, two groups of first support pins 8 are arranged on the support pin mounting plate 11, and the corresponding cross-shaped support plates of the workpiece clamp mounting base plate 4 are arranged between the two groups of first support pins 8 in the vertical direction.
The work piece holder mounting plate 4 is the cross, and the outside of work piece holder mounting plate 4 is arranged in at four apex angles of connecting plate 6, and second supporting pin 2 runs through and sets up on connecting plate 6, and second spring 3 is established to the cover on the second supporting pin 2, and second spring 3 lower extreme top is tightly on the separation blade that forms on second supporting pin 2, and second spring 3 upper end top is tightly on connecting plate 6.
The surface of the bottom of the ball head floating shaft 7 is spherical, and the upper conical surface of the ball head floating shaft 7 is matched with the lower conical surface of the centering plate 5.
The working process of the product of the invention is as follows: during processing, the cutter is pressed down. The workpiece clamp mounting bottom plate 4, the connecting plate 6 and the ball head floating shaft 7 move downwards under the action of tool pressing, and the second spring 3 is compressed. Until the spherical surface of the ball head floating shaft 7 contacts with the mounting plate 1. The centering plate 5 is separated from the ball head floating shaft 7 to form a floating gap. At this time, the workpiece can move and rotate in the x-axis, the y-axis moves and rotates, and the z-axis rotates and floats. The tool moves up and down along the machining, and the workpiece swings along with the tool. Thus, the position size of the workpiece hole is not changed, and only the aperture size is changed. The contact part of the second supporting pin 2 and the mounting plate 1 is made into a ball head, so that friction resistance between the ball head and the mounting plate 1 is reduced, and the ball head is convenient to float.
After the machining is completed, the cutter moves upwards. The workpiece clamp mounting bottom plate 4, the connecting plate 6 and the ball head floating shaft 7 move upwards under the action of the second spring 3, and the centering plate 5 is meshed with the ball head floating shaft 7. Restoring to the original position under the action of the conical surface. The rotational float around the y-axis is reset under the action of the first spring 9.
The working principle of the product of the invention is as follows: the self-centering is realized through the conical surfaces of the ball head floating shaft 7 and the centering plate 5 which are matched with each other, and the reset is realized through a spring by utilizing the clearance floating between the conical surfaces.
