Abstract
The utility model discloses a testing device for detecting the excircle of a commutator for a motor, which comprises a chassis (1) and a cradle (8), wherein an inclined slide track (6) is arranged between the chassis and the cradle, an under allowance positioning block (3) is mounted on the inclined slide track (6) near the chassis (1), an upper allowance positioning block (5) is mounted on the inclined slide track (6) near the cradle (8), and specification product channels (4) are arranged at the bottom of the inclined slide track (6) and between the upper allowance positioning block (5) and the under allowance positioning block (3). The utility model leads a commutator to roll on the inclined slide track according to a ramp theory, the excircle surface of the commutator totally contacts with a detecting surface, the excircle of an original product is avoided to line-to-line contact with the cylinder face of the testing device, thereby detecting various states of excircles of commutators. The testing device is directly applied in a production line of a commutator, which can effectively prevent bad quality of products, improves production efficiency, and lowers production cost.
Description
One, technical field
Whether qualified the utility model relate to a kind of commutator excircle dimension cylindrical detection tool that is used to detect.
Two, background technology
Existing commutator cylindrical detection tool is designed to vertical dimension (linear pattern) adjustable structure (as shown in Figure 1 and Figure 2).This cylindrical detection tool is used to detect certain size (being the commutator of a certain specification) of commutator after overregulating, at the outer bowlder that detects the commutator product, be that the bull wheel edge joint of cylinder of certain lateral side wire of product periphery and cubing touches.Like this, testing product is that line contacts with line, can not detect the periphery of whole commutator product, and test item is imperfect, can't detect bad phenomenon such as the cylindrical tapering of product, ellipses.
Three, utility model content
The purpose of this utility model is to overcome above-mentioned deficiency, and provide a kind of and can carry out comprehensively the commutator cylindrical, the correct cylindrical detection tool that detects.
The purpose of this utility model realizes by following technical solution: a kind of cylindrical detection tool, comprise base, supporting seat, between described base and supporting seat, be provided with oblique slideway, on oblique slideway, near base position, the allowance below nominal size locating piece is housed, on the oblique slideway, the difference locating piece is housed near the supporting seat place, the bottom of oblique slideway, on locate to be provided with the specification product passage between difference locating piece and the allowance below nominal size locating piece.
After adopting the utility model structure, according to the slope theory, commutator rolls on oblique slideway, the periphery of commutator and the surperficial comprehensive engagement of detection, avoided the original product cylindrical to contact with the line line on the face of cylinder of cubing, thereby can detect the various states of commutator product cylindrical, overproof or the like such as cylindrical tapering, cylindrical ellipse, excircle dimension.Therefore, the utility model compared with prior art can directly apply to the production line of commutator, can effectively prevent the quality problems that product occurs, and can reflect very soon, thereby improve production efficiency, has reduced production cost.Simultaneously, also can reflect the quality problems of commutator product comprehensively, make the user satisfied.

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.
Fig. 1 is the vertical view of known cylindrical detection tool.
Fig. 2 is the A-A cut-away view of Fig. 1.
Fig. 3 is the structural representation of the utility model cylindrical detection tool.
Fig. 4 bows to skeleton view (containing detected commutator product) for Fig. 3's.
Five, embodiment
With reference to Fig. 1, Fig. 2 as can be known, known commutator cylindrical detection tool is designed to vertical dimension (linear pattern) adjustable structure.This cylindrical detection tool is used to detect certain size (being the commutator of a certain specification) of commutator after overregulating, commutator 11 is placed between two cylinders 15 of cubing, at the outer bowlder that detects the commutator product, be that the bull wheel edge joint of cylinder of certain lateral side wire of product periphery and cubing touches.
With reference to Fig. 3, Fig. 4 as can be known, the utility model cylindrical detection tool, comprise base 1, supporting seat 8, between described base 1 and supporting seat 8, be provided with oblique slideway 6, allowance below nominal size locating piece 3 is equipped with at last, close base 1 place at oblique slideway 6 (side), go up at oblique slideway 6 (side), near poor locating piece 5 being housed supporting seat 8 places, the bottom of oblique slideway 6, on locate (close allowance below nominal size locating piece 3 places) between difference locating piece 5 and the allowance below nominal size locating piece 3 and be provided with specification product passage 4.
Wherein, the degree of tilt of this oblique slideway 6 should enough make tested commutator glide automatically; Base 1 is linked to each other by base screw 2 with oblique slideway 6; Supporting seat 8 is linked to each other by supporting seat screw 7 with oblique slideway 6; Go up poor locating piece 5, the high and low position of allowance below nominal size locating piece 3 on oblique slideway is adjustable, be movably connected by locating piece screw 9; (another) side of oblique slideway 6 also can be equipped with block 10, " runs out of " oblique slideway more effectively to prevent tested commutator.
Principle of work of the present utility model is: regulate the height and position of poor locating piece 5 on oblique slideway 6 earlier, maximum outside diameter as qualified commutator, regulate the height and position of allowance below nominal size locating piece 3 on oblique slideway 6 again, as the minimum outer diameter of qualified commutator, going up poor locating piece 5 promptly is the reasonable tolerance of qualified commutator with the difference in height of allowance below nominal size locating piece 3 on oblique slideway 6.Tested commutator is put on the oblique slideway, commutator rolling downwards automatically (as can not glide automatically, then tested commutator cylindrical circularity is defective): as not entering poor locating piece, then this tested commutator brush track diameter is excessive and defective; If can enter poor locating piece, and in the allowance below nominal size locating piece, continue again to glide, then this tested commutator brush track diameter is too small and defective; If can enter poor locating piece, but can not in the allowance below nominal size locating piece, continue to glide, then this tested commutator can be run into the allowance below nominal size locating piece, owing to be subjected to the bounce-back that stops of allowance below nominal size locating piece, then tested commutator 11 is promptly qualified by being judged to be from the specification product passage.
Claims (2)
1, a kind of cylindrical detection tool, comprise base (1), supporting seat (8), it is characterized in that: between described base (1) and supporting seat (8), be provided with oblique slideway (6), go up at oblique slideway (6), locate to be equipped with allowance below nominal size locating piece (3) near base (1), locate to be equipped with poor locating piece (5) at last, the close supporting seat (8) of oblique slideway (6), between the bottom of oblique slideway (6), last poor locating piece (5) and allowance below nominal size locating piece (3), locate to be provided with specification product passage (4).
2, cylindrical detection tool as claimed in claim 1 is characterized in that: the side of described oblique slideway (6) is equipped with block (10).
