Summary of the invention
The purpose of this utility model is to provide the device that a kind of sanding and polishing is easy to operate, be convenient to controlled working amount, high efficiency and raising hole type parts inner bore surface roughness simple in structure.
The purpose of this utility model is achieved through the following technical solutions: a kind of device that improves the hole type parts inner bore surface roughness, comprise mount pad, Compress Spring and polishing emery stick, described mount pad comprises installing handle and pedestal, described installing handle is positioned at an end of pedestal, on described pedestal, has installing hole, described Compress Spring is positioned at installing hole, one end loose fit ground of described polishing emery stick inserts in installing hole and offsets with an end of Compress Spring, the other end of polishing emery stick exposes outside installing hole, and the other end of described Compress Spring and the diapire of installing hole offset.
The exposed face of described polishing emery stick has the circular arc burnishing surface.
Described Compress Spring is two.
The installing hole bottom of described pedestal is provided with spring base hole, and the other end of described Compress Spring is inserted in spring base hole.
Described installing hole is mounting hole, and the polishing emery stick is the kidney-shaped bar.
The beneficial effects of the utility model are mainly reflected in:
1, can be by the extension elongation of adjusting installing handle and processing and the polishing that position adapts to the different-diameter hole surface;
2, clamped one time can complete processing and the polishing in hole, has saved process time;
3, the removal amount of hole surface is easy to control, and removal amount is even, improves the precision in hole;
4, simple in structure, easy to operate, practical, can realize mass automatic production.
After adopting said structure, the utility model is arranged on the boring axle of boring machine while using, the polishing that the utility model completes φ 200 * 150 circular holes only needs 4 minutes, with existing manual polishing grinding technology, compare, improved greatly operating efficiency, the utility model can by adjust installing handle in the boring axle diverse location and the pretightning force of spring realize the polishing in the hole of different-diameter, be particularly useful for the connecting rod equal aperture more than 150mm, the workpiece processing of surface roughness between 0.8 ~ 1.6.
The accompanying drawing explanation
The embodiment provided below in conjunction with accompanying drawing is described in further detail the utility model.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the right view of Fig. 1;
Fig. 3 is the A-A partial sectional view of Fig. 1;
Fig. 4 is that the utility model is arranged on the application state schematic diagram on the boring axle of boring machine.
The specific embodiment
As Fig. 1, shown in 2, a kind of device that improves the hole type parts inner bore surface roughness, comprise mount pad 1, Compress Spring 3 and polishing emery stick 2, described mount pad 1 comprises installing handle 1-1 and pedestal 1-2, described installing handle 1-1 is positioned at the end of pedestal 1-2, on described pedestal 1-2, has installing hole 1-3, described Compress Spring 3 is positioned at installing hole 1-3, one end loose fit ground of described polishing emery stick 2 inserts in installing hole 1-3 and offsets with an end of Compress Spring 3, the other end of polishing emery stick 2 exposes outside installing hole 1-3, the diapire of the other end of described Compress Spring 3 and installing hole 1-3 offsets.
As shown in Figure 1, 2, 3, the exposed face of described polishing emery stick 2 has circular arc burnishing surface 2-1.
As shown in Figure 1, 2, described Compress Spring 3 is two.
As shown in Figure 1, the installing hole 1-3 of described pedestal 1-2 bottom is provided with spring base hole 1-4, and the other end of described Compress Spring 3 is inserted in spring base hole 1-4.
As shown in Figure 2, described installing hole 1-3 is mounting hole, and polishing emery stick 2 is the kidney-shaped bar.
Compress Spring 3 in the utility model can adopt YA 1.0 * 10 * 15, GB/T2089-94 standard cylindroid helical-coil compression spring.Also can adopt other Compress Spring.
As shown in Figure 4, the installing hole of on the boring axle 4 of installing handle 1-1 of the present utility model and boring machine, boring cutter being installed matches, the size of installing handle 1-1 can be with reference to the boring cutter boring bar, the width of the installing hole 1-3 of pedestal 1-2 and length can be done corresponding the adjustment according to diameter and the thickness of the hole 5-1 of institute's workpiece 5, and the size of spring base hole 1-4 is slightly larger than the external diameter of Compress Spring 3.The circular arc burnishing surface 2-1 radius of polishing emery stick 2 is slightly less than the radius of the machining hole 5-1 of institute, and the length of polishing emery stick 2 and thickness can be adjusted accordingly according to diameter and the thickness of hole 5-1.
