Problems solved by technology

[0004] When the workpiece is large, heavy or not suitable for manual clamping, use ordinary fixtures to locate and clamp the workpiece. Because there are machining errors in the positioning datum of the workpiece and the position of the machined hole, it is difficult for the central axis of the hole to align with the axis of the honing head. Overlapping, affected by the accuracy of the workpiece clamping position and gravity, the hole of the workpiece exerts a radial deflection force on the honing head, causing the axis of the honing head to bend and deform. During honing, the straightness and shape accuracy of the hole will be affected. Reduce the processing quality of the hole

Embodiment 1

[0026] Such as Figure 1 to Figure 4 , the elastic suspension honing device of the present invention comprises a base plate 7 fixedly installed on the honing equipment, a wire rail 9 screwed on the base plate 7, a slide block 8 and a wire rail 9 to form a linear guide rail pair, and the axis 90 of the wire rail is connected to the The axis 100 of the honing head is parallel, and the slider 8 flexibly reciprocates along the axis 90 of the line rail. Two limit stops 10 are distributed at both ends of the slider 8 and fixedly connected in the groove of the bottom plate 7. Adjust the limit stop 10 The position in the groove of the bottom plate 7 can control the stroke of the slider 8 . The mounting plate 5 and the slider 8 are fixedly connected together by screws, the elastic suspension mechanism 3 is arranged on the mounting plate 5, and the two baffle plates 4 are divided into the two ends of the hole of the workpiece and are screwed on the mounting plate 5. Two O-rings 40 are ...

Embodiment 2

[0036] Such as Figure 5 As shown, the elastic suspension mechanism uses a universal ball bearing 31 as the elastic supporting element, and the rest of the structure is the same as that of the first embodiment.

Embodiment 3

[0038] Such as Figure 6 As shown, the material of the baffle plate 4 is engineering plastics, no O-ring 40 is used, no universal ball bearing 31 is used, the upper end surface of the suspension sleeve 14 is a spherical surface, which is in point contact with the bottom of the workpiece 1, and the rest of the structure is the same as that of Embodiment 1. same.

Abstract

The invention belongs to the technical field of honing and particularly relates to an elastic suspension honing device for clamping workpieces in honing processing. The elastic suspension honing device comprises a baseboard fixedly connected onto a honing device, a linear rail fixedly connected with the baseboard, a sliding block slidingly matched with the linear rail, an installation board fixedly integrated with the sliding block, a limiting stop block installed on the baseboard, a driving rod fixedly connected with the installation board, blocking boards arranged on the installation board, an O-shaped ring installed on the blocking board, an elastic suspension mechanism arranged on the installation board and the like. The elastic suspension honing device is characterized in that the two blocking boards are distributed at two ends of a workpeice hole and are fixedly connected onto the installation board, movable gaps are reversed between the blocking boards and two ends of the workpiece hole, the workpieces are placed between the elastic suspension mechanism and the blocking boards, the weight of the workpieces are balanced under the elastic support of the elastic suspension mechanism, the axis of the workpiece hole coincides to the axis of a honing head, and the workpieces achieve reciprocate reversing and linear feeding along the axis of the honing head under dragging of the two blocking boards. The elastic suspension honing device is simple in structure and convenient to operate, can reduce influence of gravity of the workpieces and improves honing processing accuracy of the hole.

Description

technical field [0001] The invention belongs to the technical field of honing, and in particular relates to an elastic suspension honing device for clamping workpieces during honing processing. Background technique [0002] Honing process is mostly used for the finishing of round holes that require high dimensional accuracy, shape accuracy, and surface finish. [0003] When the volume and weight of the workpiece is small, the workpiece is generally manually clamped and moved back and forth along the axis of the honing head to realize the honing process of the workpiece. The gravity of the workpiece itself will affect the machining accuracy of the honed hole. [0004] When the workpiece is large, heavy or not suitable for manual clamping, use ordinary fixtures to locate and clamp the workpiece. Because there are machining errors in the positioning datum of the workpiece and the position of the machined hole, it is difficult for the central axis of the hole to align with the ...
