Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of speed reducer box machining technology, specifically relates to a screw conveying guide rail structure. BACKGROUND

[0002] When machining the speed reducer box, the output shaft, flange and shell and other components need to be assembled and connected by screws to form the speed reducer box finished product. At present, screw conveying guide rail is mostly used for automatic feeding of screws to improve the degree of automation and processing efficiency in the processing process.

[0003] The existing screw conveying guide rail is a single groove structure, that is, it only contains a single guide rail groove, and the screw moves in the guide rail groove in the direction of the screw rod downward and the screw cap upward to realize automatic feeding. However, for such a screw conveying guide rail, when the feeding mechanism (such as a vibrating tray) feeds the screw to the guide rail groove, the screw is prone to jamming at the feeding end of the conveying guide rail due to the deviation of the screw direction, directly affecting the feeding efficiency of the screw and the processing efficiency of the speed reducer box. SUMMARY

[0004] The utility model aims at providing a screw conveying guide rail structure to solve the problem of easy jamming during screw conveying.

[0005] The screw conveying guide rail structure of the utility model is implemented as follows:

[0006] A screw conveying guide rail structure comprises

[0007] A conveying seat is provided with a horizontal through guide rail groove above;

[0008] A transition block is detachably installed in the guide rail groove and located at the feeding end of the guide rail groove, the upper surface of the transition block is provided with a concave arc-shaped groove, and the axial direction of the arc-shaped groove is parallel to the guide rail groove.

[0009] Further, the conveying seat comprises a bottom plate and two vertical plates arranged in parallel on the bottom plate to form the guide rail groove, and the inner walls of the two vertical plates are provided with transversely and oppositely arranged convex strips.

[0010] Further, one of the vertical plates is provided with an inner-high outer-low inclined surface at the feeding end of the guide rail groove, and the inner edge of the inclined surface is flush with the upper surface of the convex strip.

[0011] Further, the inclination angle of the inclined surface is 45°-60°.

[0012] Further, a vertical blocking rod is installed on the inclined surface.

[0013] Further, the upper surface height of the transition block is not higher than the upper surface height of the convex strip.

[0014] Further, the bottom of the transition block is provided with a limiting strip matched with the bottom of the convex strip.

[0015] Further, the transition block is fixed on the vertical plate on its two sides through screws.

[0016] Further, the vertical plate is provided with a weight-reducing hole arranged transversely.

[0017] Further, the bottom plate is provided with a mounting hole.

[0018] After the above technical scheme is adopted, the screw conveying guide rail structure has the beneficial effects that:

[0019] The transition block is arranged at the feeding end of the guide rail groove, so that the screw conveyed by the feeding mechanism is transferred to the conveying guide rail, thereby avoiding the problem that the screw is stuck at the feeding end of the conveying guide rail, effectively improving the conveying efficiency of the screw and the machining efficiency of the reducer box.

DETAILED DESCRIPTION

[0027] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but rather merely represents selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figure 1-5 As shown, a screw conveying guide rail structure includes a conveying seat 1 and a transition block 2. The conveying seat 1 is provided with a transversely penetrating guide rail groove 3; the transition block 2 is detachably installed in the guide rail groove 3 and is located at the feeding end of the guide rail groove 3. The upper surface of the transition block 2 is provided with a concave arc groove 4, and the axial direction of the arc groove 4 is parallel to the guide rail groove 3.

[0030] When the screw 14 is conveyed in the guide rail groove 3, it is conveyed with the screw rod facing downward and the screw 14 cap facing upward. When the screw 14 is conveyed from the feeding mechanism (such as a vibrating material tray), it is placed horizontally (that is, the axial direction is the same as the guide rail groove 3). Through the setting of the transition block 2, the screw 14 can be smoothly conveyed from the feeding mechanism to the conveying guide rail structure. After passing through the transition block 2, the screw 14 is rotated again so that the screw rod falls vertically into the track groove, and then continues to be conveyed backward.

[0031] The arc groove 4 on the upper surface of the transition block 2 can cooperate with the outer ring surface of the screw cap 14, so as to better receive the horizontally placed screw 14 and avoid the screw 14 from getting stuck at the feeding end of the guide rail groove 3.

[0032] In order to guide the screws 14, the conveying seat 1 includes a base plate 1-1 and two vertical plates 1-2 arranged parallel to the base plate 1-1 to form a guide groove 3. The inner walls of the two vertical plates 1-2 are provided with transverse and oppositely arranged convex strips 5.

[0033] The ridges 5 are provided to restrict the direction of screw 14 during transport. Specifically, the spacing between the two ridges 5 is greater than the outer diameter of the screw shaft 14 but less than the outer diameter of the screw cap 14. This allows screw 14 to be transported only with the shaft facing downward and the cap 14 facing upward. The upper surface of the ridges 5 also provides support for the cap 14, ensuring stable transport of the screw 14.

[0034] Preferably, the bottom plate 1-1 and the vertical plate 1-2 are integrally arranged, which can effectively increase the structural strength and stability of the entire screw conveying guide rail.

[0035] When the screws 14 placed horizontally on the transition block 2 are rotated to be placed vertically and fall into the track groove, it is inevitable that the caps of the screws 14 will face downwards. At this time, due to the large outer diameter of the caps of the screws 14, they cannot fall into the track groove. In order to be able to remove the screws 14 with improper directions and positions (i.e., misplaced screws 14) to avoid affecting the subsequent conveying efficiency of the screws 14, one of the vertical plates 1-2 is located at the feeding end of the guide rail groove 3 and is provided with a slope 6 with a high inside and a low outside, and the inner edge of the slope 6 is flush with the upper surface of the convex strip 5.

[0036] The inner edge of the inclined surface 6 is flush with the upper surface of the ridge 5, and the offset screw 14 will be supported on the ridge 5 and the inclined surface 6. Then, due to the inclination of the inclined surface 6, the screw 14 will slide down along the inclined surface 6 under the action of its gravity, thereby facilitating the continued transportation of the subsequent screw 14.

[0037] Preferably, the inclination angle of the inclined surface 6 is 45° to 60°.

[0038] The larger the inclination angle of the inclined surface 6 is within the above-mentioned angle range, the better. The larger the angle is, the more effective and efficient the sliding of the screw 14 can be.

[0039] In order to prevent the misplaced screws 14 from not sliding off the inclined surface 6 and affecting the continued delivery of the subsequent screws 14, a vertically arranged blocking rod is installed on the inclined surface 6.

[0040] In this embodiment, a plurality of bolt holes 7 are provided on the inclined surface 6, and the blocking rod adopts a bolt 8 assembled in the bolt hole 7. When the dislocation screw 14 moves to the blocking rod position, it can be blocked by the blocking rod and then slide down from the inclined surface 6.

[0041] In addition, since the inclined surface 6 does not extend to the discharge end of the side vertical plate 1-2 on which it is located, the end of the vertical plate 1-2 connected to the inclined surface 6 forms a vertical blocking surface 13. If the bolt 8 does not remove the misplaced screw 14, the blocking surface 13 can play a blocking role and block the misplaced screw 14 again, thereby ensuring that the misplaced screw 14 can be completely removed.

[0042] In order to achieve the transition of the screw 14 and ensure that it can subsequently rotate in the direction and fall into the guide rail groove 3, the upper surface height of the transition block 2 is not higher than the upper surface height of the protruding strip 5.

[0043] In order to facilitate the positioning of the height of the transition block 2 , limiting strips 9 that fit into the bottom of the convex strips 5 are provided on both sides of the bottom of the transition block 2 .

[0044] When assembling the transition block 2 , the limiting strip 9 at the bottom thereof is placed against the bottoms of the two convex strips 5 , so that the height of the transition block 2 can be positioned.

[0045] In order to achieve detachable installation of the transition block 2, the transition block 2 is fixed to the vertical plates 1-2 on both sides thereof by screws.

[0046] The vertical plate 1 - 2 without the inclined surface 6 is provided with a screw hole 10 , in which a screw for connecting the transition block 2 and the vertical plate 1 - 2 is installed.

[0047] In order to reduce the weight of the entire screw conveying guide rail, a horizontally arranged weight-reducing hole 11 is provided on the vertical plate 1 - 2 .

[0048] The weight-reducing holes 11 on the two vertical plates 1 - 2 are arranged opposite to each other. The arrangement of the weight-reducing holes 11 can also facilitate observation of the delivery status of the screws 14 .

[0049] In order to be able to install the screw conveying guide rail on the processing equipment, a mounting hole 12 is provided on the base plate 1 - 1 .

[0050] The utility model has a simple overall structure and can effectively avoid the problem of the screw 14 being stuck at the feeding end of the guide rail groove 3, thereby ensuring smooth feeding of the screw 14 and improving the feeding efficiency of the screw 14 and the processing efficiency of the reducer housing.

[0051] Based on the above-mentioned ideal embodiment of the present invention, and in accordance with the above description, relevant personnel can make various changes and modifications without departing from the technical scope of the present invention. The technical scope of the present invention is not limited to the content of the specification, but must be determined according to the scope of the claims.
