Description
Technical field:
The utility model relates to Transmission field of mechanical technique, refers in particular to a kind of screw conveying mechanism with detecting device.
Background technology:
In automated machine processing industry, need a large amount of use screws.As shown in Figure 1, in order to strengthen fastening force and the steadiness of screw, usually need a sheathed elastomeric pad 3 and flat pad 4 on screw 2.Due to screw 2 small volume, when sheathed pad, easily make a fault, cause sheathed pad quantity not right, such as occur disposable sheathed two elastomeric pads 3 or flat pad 4, or omit sheathed elastomeric pad 3 or flat pad 4, or the order of sheathed pad is not right.Cause like this going wrong in follow-up operation.And existing screw transport sector does not arrange detecting device, normally adopt the macroscopic mode of operating personal to detect pad quantity, whether order is correct, occur careless omission unavoidably.
Utility model content:
The purpose of this utility model is to overcome the deficiencies in the prior art, provides a kind of and can detect the whether correct screw conveying mechanism with detecting device of pad quantity.
In order to solve the problems of the technologies described above, the utility model have employed following technical proposals: this screw conveying mechanism with detecting device comprises: transmission path, this transmission path offers the transmission groove that can hold screw threaded shank and insert, the threaded shank of described screw is arranged with elastomeric pad and flat pad, described transmission path is provided with detecting device, and this detecting device comprises: pin and limiting groove; Described pin is horizontal above transmission groove, and the superposition thickness of the nut portion of screw, elastomeric pad, flat pad is suitable with the distance of pin Distance Transmission groove end face; The height of described limiting groove is suitable with the thickness of flat pad.
Furthermore, in technique scheme, described pin one end is fixed on one and is positioned on the column of transmission path side.
Furthermore, in technique scheme, described transmission path is fixed with a plane clamp, the limiting groove described in the gap between this plane clamp and transmission groove end face is formed.
Furthermore, in technique scheme, the side of described clamp is fixed on a pedestal, and this pedestal is fixed on transmission path side.
After adopting technique scheme, the utility model has following beneficial effect compared with prior art: with the thickness that superposes of pad, the utility model judges whether the sheathed quantity of pad, order be correct by detecting screw nut portion.When pad quantity sheathed on screw not pair time, whole screw just cannot pass through detecting device, and such operating personal just can identify easily, thus makes corresponding remedial measures.The utility model structure is simple, Be very effective.
Accompanying drawing illustrates:
Fig. 1 is the front view that screw coordinates with pad;
Fig. 2 is birds-eye view of the present utility model;
Fig. 3 is front view of the present utility model;
Fig. 4 be in Fig. 2 A-A to cutaway view.
Detailed description of the invention:
Below in conjunction with specific embodiments and the drawings, the utility model is further illustrated.
As shown in Figure 1, this is the screw assembly that the utility model transport sector needs transmission.It comprises: screw 2, and the elastomeric pad 3 be set in successively in screw threaded shank 21 and flat pad 4.The diameter in the nut portion 22 of screw is slightly larger than the diameter of elastomeric pad 3, and flat pad 4 is mainly played a supporting role, thus its diameter comparatively nut portion 22, elastomeric pad 3 are large, and thinner thickness.So these features can be utilized to arrange detecting device.
See Fig. 2 to Fig. 4, screw conveying mechanism of the present utility model mainly comprises a transmission path 1, this transmission path 1 offers the transmission groove 10 that can hold screw 2 threaded shank 21 and insert, the width of transmission groove 10 is greater than the diameter of screw screw rod 21, but be less than the diameter of flat pad 4, suitable with the diameter of elastomeric pad 3.Whole like this screw placement, when transmitting in groove 10, is suspended on transmission groove 10 by flat pad 4.Transmission path 1 can realize advancing of whole screw by the mode of vibration.
Described transmission path 1 is provided with detecting device, and this detecting device mainly detects two problems: how sheathed pad is; Pad is few sheathed.Because the thickness of nut portion 22, elastomeric pad 3 and flat pad 4 is certain, so the screw of each correct sheathed pad, the superposition thickness of its nut portion 22, elastomeric pad 3 and flat pad 4 is consistent substantially, and setting this superposition thickness is L.If any one pad how sheathed, this superposition thickness will change into L1, and can determine that L1 is greater than L.Same, if few any one pad sheathed, this superposition thickness will change into L2, and can determine that L2 is less than L.
The utility model detects by pin 5 situation that L1 is greater than L.Described pin 5 is horizontal above transmission groove 10, and the distance of the superposition thickness L1 of the nut portion 22 of screw 2, elastomeric pad 3, flat pad 4 and pin 5 Distance Transmission groove 10 end face is suitable, namely the distance of pin 5 Distance Transmission groove 10 end face just can be greater than L, when being greater than the situation of L like this if there is L1, this screw just cannot pass through pin 5, is limited by pin 5.
Described pin 5 one end is fixed on one and is positioned on the column 51 of transmission path 1 side, adjusts the distance of its Distance Transmission groove 10 end face by the height of adjustment pin 5 on column 51.
The utility model detects by limiting groove 6 situation that L2 is less than L.
Described transmission path 1 is fixed with a plane clamp 61, the limiting groove 6 described in the gap between this plane clamp 61 and transmission groove 10 end face is formed.And the thickness of the height of this limiting groove 6 and flat pad 4 is suitable.The side of described clamp 61 is fixed on pedestal 62, and this pedestal 62 is fixed on transmission path 1 side.
When the sheathed quantity of screw 2 Upper gasket, order are correct.When whole screw 2 is by limiting groove 6 region, flat pad 4 is just in time passed by limiting groove 6, and the thickness of plane clamp 61 thickness being construed as limiting groove 6 and elastomeric pad 3 quite, and the edge of plane clamp 61 just in time holds elastomeric pad 3 to be passed through.
If few any one pad sheathed on screw 2, this superposition thickness will change into L2, and can determine that L2 is less than L.If the sheathed sequence error of sheathed elastomeric pad 3 and flat pad 4, nut portion 22 will directly be superimposed upon in flat pad 4, and now flat pad 4 is by too high, and the edge with plane clamp 61 is formed by it interferes, and causing cannot by limiting groove 6 region.
If sheathed two flat pad 4, and forget sheathed elastomeric pad 3, although whole screw 2 can pass through pin 5, pass because limiting groove 6 only can hold a slice flat pad 4, so in this case, screw 2 still cannot by the region of limiting groove 6.
If sheathed two elastomeric pads 3, and forget sheathed flat pad 4, the superposition thickness of whole screw 2 increases, and cannot pass through pin 5.
If a sheathed elastomeric pad 3, and forget sheathed flat pad 4, now whole screw 2 loses the support of flat pad 4, will easily fall in transmission groove 10.
With the thickness that superposes of pad, the utility model judges whether the sheathed quantity of pad, order be correct by detecting screw nut portion.When pad quantity sheathed on screw, order not pair time, whole screw just cannot pass through detecting device, and such operating personal just can identify easily, thus makes corresponding remedial measures.The utility model structure is simple, Be very effective.
Certainly, the foregoing is only specific embodiment of the utility model, be not limit the utility model practical range, all equivalences done according to structure, feature and principle described in the utility model claim change or modify, and all should be included in the utility model claim.
