Abstract
The utility model discloses a grinding head rotating device for a sander, which comprises a grinding head and a soleplate which are fixedly connected. The soleplate is provided with a convex step bore, the grinding head is provided with a tubular shaft which can be inserted into the convex step bore, and the end of the tubular shaft is at least provided with two barbs which are hooked on steps of the convex step bore. The is also provided with a downwards opened counter bore, a spring is arranged in the counter bore, a steel ball is arranged under the spring, and the steel ball is tightly pressed by the spring and is embedded into a position bore on the soleplate. The grinding head and the soleplate of the utility model can rotate and be fixed, and therefore, the utility model can make full use of abrasive paper for operation and is suitable for being used on a triangle sander.
Description
The utility model relates to a kind of sander.
Sander comprises body and bistrique two large divisions, and bistrique is fixed on the body by support, and the motor in the body makes bistrique do oscillating traverse motion by eccentric stiffener, thereby workpiece is carried out the sanding operation, bistrique has base plate, and base plate has sand paper, and sand paper contacts with workpiece.After sand paper work a period of time, local meeting is worn and torn and is lost the sanding effect, just can work on after needing to change sand paper, triangle sander particularly, when work, often only utilize the one angle, and two other angle of sand paper can also continue to use, and can cause waste so change sand paper, and it is cumbersome that sand paper is turned over an angle.
The purpose of this utility model is: a kind of bistrique whirligig of sander is provided, and the bistrique of this device and base plate can rotate and be fixing, and therefore can make full use of sand paper carries out operation, is particularly suitable for using at the triangle sander.
The technical solution of the utility model is: a kind of bistrique whirligig of sander, comprise the bistrique and the base plate that are connected and fixed, described base plate is provided with the type stepped hole, bistrique is provided with the tubular shafts that inserts in the type stepped hole, the termination of tubular shafts is provided with two barbs at least and is hooked on the step of type stepped hole, also is provided with the counterbore that Open Side Down on the described bistrique, is provided with spring in the counterbore, spring has steel ball, and steel ball is by spring compression and embed in the location depression on the base plate.
The further technical scheme of the utility model is: a kind of bistrique whirligig of sander, comprise the bistrique and the base plate that are connected and fixed, described base plate is provided with the type stepped hole, bistrique is provided with the tubular shafts that inserts in the type stepped hole, the termination of tubular shafts is provided with two barbs at least and is hooked on the step of type stepped hole, also is provided with the counterbore that Open Side Down on the described bistrique, is provided with spring in the counterbore, spring has steel ball, and steel ball is by spring compression and embed in the location depression on the base plate; Be provided with end cap in the following stomidium of described tubular shafts, with the barb tensioner.
The better technical scheme of the utility model is: a kind of bistrique whirligig of sander, comprise the bistrique and the base plate that are connected and fixed, described base plate is provided with the type stepped hole, bistrique is provided with the tubular shafts that inserts in the type stepped hole, the termination of tubular shafts is provided with two barbs at least and is hooked on the step of type stepped hole, also is provided with the counterbore that Open Side Down on the described bistrique, is provided with spring in the counterbore, spring has steel ball, and steel ball is by spring compression and embed in the location depression on the base plate; Be provided with end cap in the following stomidium of described tubular shafts, with the barb tensioner; The upper surface of described base plate is provided with circular friction teeth, and the lower surface of bistrique is provided with two sections arc friction teeth, and circular friction teeth contacts with the arc friction teeth and offsets.
The utility model has the advantages that:
1. bistrique of the present utility model utilizes stepped hole to be connected with tubular shafts with base plate, makes both both can be fastened to each other, can rotate relatively again, make the sand paper concentrated wear after, still can continue to use as long as turn over an angle.
2. the utility model also has end cap at the following stomidium inner cap of tubular shafts, and end cap can be with two or three barb tensioners, thereby make bistrique more reliable with being connected of base plate, guarantee in the course of work can not come off.
3. bistrique of the present utility model is provided with spring and steel ball, in the location depression on the steel ball embedding base plate, can make base plate that a definite position is arranged when rotated, also can play positioning action simultaneously.
4. be respectively equipped with the arc friction teeth and the circular friction teeth that cooperatively interact on bistrique of the present utility model and the base plate, make bistrique and base plate relative fixed and can not rotating in the course of the work.
The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the upward view of bistrique;
Fig. 3 is the vertical view of base plate;
Wherein: 1 bistrique; 2 base plates; 3 type stepped holes; 4 tubular shafts; 5 barbs; 6 counterbores; 7 springs; 8 steel balls; 9 location depressions; 10 end caps; 11 circular friction teeth; 12 arc friction teeth; 13 sand paper; 14 felt paper; 15 screws; 16 supports.
Embodiment: as shown in the figure, a kind of bistrique whirligig of sander, comprise the bistrique [1] and the base plate [2] that are connected and fixed, described base plate [2] is provided with type stepped hole [3], bistrique [1] is provided with the tubular shafts [4] that inserts in the type stepped hole [3], the termination of tubular shafts [4] is provided with three barbs [5] and is hooked on the step of type stepped hole [3], also be provided with three counterbores that Open Side Down [6] on the described bistrique [1], be provided with spring [7] in the counterbore [6], spring [7] has steel ball [8], and three steel balls [8] are compressed and embed respectively on the base plate [2] three the location depressions [9] by spring [7]; Be provided with end cap [10] in the following stomidium of described tubular shafts [4], with three barbs [5] tensioner; The upper surface of described base plate [2] is provided with circular friction teeth [11], and the lower surface of bistrique [1] is provided with two sections arc friction teeth [12], and circular friction teeth [11] contacts with arc friction teeth [12] and offsets.
The utility model is particularly suitable for the triangle sander and uses, because the triangle sander often has the sand paper wearing and tearing at an angle than very fast when work, after work a period of time, base plate [2] can be turned over 120 degree, with another angle work of sand paper, such sand paper just can use three times.
