Background technology

For attractive in appearance or indicate explanation, usually print on the hard shell of industrial products and go up various patterns or literal, in order to test the wearing quality of these patterns or literal, need pattern on the hard shell of industrial products or literal are carried out friction test, to check its scuff resistance.For this reason, need design a kind of testing machine that detects scuff resistance.

The utility model content

The purpose of this utility model is to provide a kind of application of force equilibrium, frictional testing machine easy to operate, simple in structure.

For achieving the above object, technical solution of the present utility model is:

The utility model is a kind of frictional testing machine, and it comprises board, height adjustment mechanism, motor, gear train, grip slipper, sliding shoe, take-up housing, pole, wiping head, counterweight; Column in the described height adjustment mechanism is vertically fixed on the board, and motor is installed on the board; Described take-up housing is installed in the middle part of column, and sliding shoe is fixed on a side of take-up housing; The output shaft of described motor connects grip slipper and drives grip slipper reciprocating by gear train, a side of grip slipper is provided with chute, and this chute slips on sliding shoe and can move around along sliding shoe; Described pole gap is set in the mesopore of grip slipper, and counterweight is articulated in the top of pole, and affixed one wipes head in the lower end of pole.

Described pole be set in by linear bearing in the mesopore of grip slipper and can along in axially bored line freely move up and down.

Offer a draw-in groove around full week on the top of pole, the holding of jump ring sheet is in this draw-in groove; Described counterweight is socketed on the pole and by the jump ring sheet from the upper end of pole and withstands.

Described height adjustment mechanism is made up of two root posts, height control hand wheel, screw rod, crossbeam; The lower end of described two root posts is fixed on the board, and the two ends of crossbeam are connected across the top of two root posts; Described height control hand wheel is fixed in the top of screw rod, and through hole and its middle part that the crossbeam middle part is passed in the downward gap of screw rod are screwed onto in the screw at take-up housing middle part.

The utility model also comprises the product orientation clamping tool, and this product orientation clamping tool is installed on the board table top.

After adopting such scheme, be set in the mesopore of grip slipper because the utility model can add the pole gap of counterweight, the gravity that the wiping head of pole rod end is bestowed the product of detection remains constant, the friction force equilibrium that produces at product surface.Counterweight of the present utility model is that the mode with socket is socketed on the pole, can increase or reduce counterweight as required at any time, and convenience very operates.And parts of the present utility model are less, and structure is comparatively simple, and is with low cost.

Below in conjunction with the drawings and specific embodiments the utility model is further described.

Description of drawings

Fig. 2 is a front elevation of the present utility model;

Fig. 3 is a side view of the present utility model;

Fig. 4 is a vertical view of the present utility model.

Embodiment

As Fig. 1-shown in Figure 4, the utility model is a kind of frictional testing machine, and it comprises board 1, height adjustment mechanism 2, motor 3, gear train 4, grip slipper 5, sliding shoe 6, take-up housing 7, pole 8, wipe 9, counterweight 10, product orientation clamping tool 20.

Described height adjustment mechanism 2 is made up of two root posts 21, height control hand wheel 22, screw rod 23, crossbeam 24.The lower end of described two root posts 21 is fixed on the board 1, and the two ends of crossbeam 24 are connected across the top of two root posts 21; Described height control hand wheel 22 is fixed in the top of screw rod 23, and through hole and its middle part that crossbeam 24 middle parts are passed in screw rod 23 downward gaps are screwed onto in the screw at take-up housing 6 middle parts.

Described motor 3 is installed on the board 1; Described take-up housing 7 is installed in the middle part of column 21, and sliding shoe 6 is fixed on a side of take-up housing 7; The output shaft of described motor 3 connects grip slipper 5 and drives grip slipper 5 reciprocating by reciprocating type gear train 4, a side of grip slipper 5 is provided with chute 51, and this chute 51 slips on sliding shoe 6 and can move around along sliding shoe 6.

Described pole 8 be set in by linear bearing in the mesopore of grip slipper 5 and can along in axially bored line freely move up and down, offer a draw-in groove around full week on the top of

pole

8,30 holdings of jump ring sheet are in this draw-in groove; Described counterweight 10 is socketed on the pole 8 and by jump ring sheet 30 from the upper end of pole 8 and withstands, and can not fall.Affixed one wipes 9 in the lower end of pole 8.

Described product orientation clamping tool 20 is installed on board 1 table top, is used for fixing the product that needs detect.

Principle of work of the present utility model:

Motor 3 drives grip slipper 5 by gear train 4 and moves reciprocatingly along sliding shoe 6, and pole 8 freely moves up and down in the mesopore of grip slipper 5 with sliding shoe 6 to-and-fro movements simultaneously.When wiping 9 need add certain power and carry out the friction testing product surface time, can be by the counterweight 10 that superposes in pole 8 upper ends, counterweight 10 drops on the jump ring sheet 30, gravity is delivered to by jump ring sheet 30 and pole 8 and wipes 9, wipe 9 and contact with product surface, when product surface had the camber line variation, wiping 9 moved up and down with pole 8, guarantee to wipe 9 and contact all the time well with product surface, and the gravity that is added in wiping 9 to remain unchanged be that the friction force of product surface is constant.

Emphasis of the present utility model just is: the pole gap that can add counterweight is set in the mesopore of grip slipper.

The above, it only is the utility model preferred embodiment, the mounting means of counterweight on pole can have various, so can not limit the scope that the utility model is implemented with this, the i.e. equivalence of doing according to the utility model claim and description changes and modifies, and all should still belong in the scope that the utility model patent contains.
