Description

Technical Field

[0001] The utility model relates to the field of processing tooling, in particular to a shaft gear part hanger. Background Art

[0002] For relatively heavy mechanical parts, processing or handling requires the design of suitable lifting equipment to assist with processing or handling at the production site and reduce the workload. However, the weight and unique structure of some mechanical parts present significant challenges in lifting equipment design. For example, a shaft weighing 20-30 kg has a spline in the middle, and immediately adjacent to the spline are splined oil grooves with radial oil holes on the outer diameter of the groove. During processing, the shaft must be adjusted between various positions, sometimes vertical, sometimes reversed, and sometimes horizontal. Furthermore, the gripping area of ​​the lifting equipment must not interfere with the machining fixtures, machine tools, the product cart (the container that holds the parts), or adjacent parts on the cart. Furthermore, the gripping efficiency must be high. Currently, no lifting equipment meets these requirements. Utility Model Content

[0023] 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, rather than all the embodiments.

[0024] Please also see Figure 1 and Figure 2 , are respectively a structural schematic diagram of the shaft gear parts hanger provided by the utility model, and a partial enlarged diagram thereof at the rotating shaft position.

[0025] The shaft gear parts lifting fixture includes a lifting lug 1, a bent rod 2, a sleeve 3, a rotating shaft 4, a posture positioning plate 5 and a clamp 6.

[0026] The bent rod 2 is an L-shaped rod. Figure 1 From the perspective shown, a lifting lug 1 is welded to the upper left end of the bent rod 2, and a sleeve 3 is welded to the lower end. Sleeve 3 is cylindrical and axially horizontal, with its upper left end welded to the bent rod 2. The inner wall of sleeve 3 is appropriately enlarged at both ends to form a stepped structure for mounting a bearing 31, which abuts the outer ring end of bearing 31.

[0027] The rotating shaft 4 is inserted into two bearings 31 and rotates on these bearings. The right end of the rotating shaft 4 is aligned with the right end of the sleeve 3, and the left end extends outside the sleeve 3. The left end of the rotating shaft 4 is thickened to form a stepped structure, which abuts the inner end of the left bearing 31. The right end of the rotating shaft 4 is grooved on the outer wall and equipped with a shaft circlip, which abuts the inner end of the right bearing 31.

[0028] Please also see Figures 2 to 4 , which are respectively a partial enlarged view at the shaft position and a stereoscopic view of the attitude positioning disk from the front and back perspectives.

[0029] A countersunk hole is provided at the center position of the right end of the rotating shaft 4. The head of the countersunk hole is a square hole, and the tail is a circular blind hole with a threaded inner wall.

[0030] The attitude positioning plate 5 includes a plate body 51 , a positioning lever 52 and a spring 53 .

[0031] The disc 51 is a circular disc with a diameter matching the outer diameter of the sleeve 3. Its left side, centered on a circle, features three stepped steps. Starting from the left end, the first step is a square platform with a thickness similar to that of the disc 51. The second step is a thinner circular platform. The third step is the disc 51. The first step of the disc 51 engages with the head of the countersunk hole on the shaft 4. The second step mates with the right end of the shaft 4 and aligns with its outer wall. The third step aligns with the outer wall of the sleeve 3.

[0032] The square head of the disc body 51 fits into the square hole of the rotating shaft 4 to achieve internal and external square matching, so that the disc body 51 can smoothly drive the rotating shaft 4 to rotate synchronously when rotating.

[0033] A countersunk hole is provided at the center of the right side of the disc body 51, which is aligned with the countersunk hole provided on the rotating shaft 4. The disc body 51 is fixedly connected to the rotating shaft 4 by inserting a hexagon socket screw into the countersunk hole of the disc body 51 and screwing it into the tail end of the countersunk hole of the rotating shaft 4.

[0034] The right side of the disk 51 has a thickened area extending radially from the center. A circular through-hole 511 is drilled in this thickened area, near the edge of the disk 51, extending left and right through the disk 51. A positioning lever 52 is inserted into through-hole 511. The middle of the positioning lever 52 is hinged to the right side of the through-hole, and a hinge hole 512 is provided at this hinged location.

[0035] Both ends of the positioning lever 52 extend out of the disc body 51. The left end of the positioning lever 52 is always located on the right side of the right bearing 31 and does not interfere with the bearing 31 and the shaft elastic retaining ring. The right end of the positioning lever 52 extends a long length and is used as a handle.

[0036] A spring hole 513, deeper than the aforementioned oval-shaped through hole, is drilled radially along the side of the disk body 51, near the left side. Spring 53 is mounted therein. Spring 53 is a compression spring. Spring hole 513 cuts through the left side of the disk body 51, but does not cut through the second step of the disk body 51.

[0037] Under the above structure, the left end of the positioning lever 52 is pushed by the spring 53 to rotate counterclockwise, and the limit position of rotation is when the upper side wall of the positioning lever 52 abuts against the disk body 51;

[0038] If force is applied to the right end of the positioning lever 52 to push the compression spring 53 and rotate clockwise, the limit position of rotation is when the left end of the positioning lever 52 abuts against the rotating shaft 4.

[0039] The right end of the sleeve 3 is provided with eight notches 32 at equal intervals along its circumference.

[0040] When the positioning lever 52 is pushed by the spring 53 and rotates counterclockwise:

[0041] If the positioning lever 52 is at any position of the notch 32 , the positioning lever 52 will reach the limit position in the notch 32 and abut against the plate 51 ;

[0042] If the positioning lever 52 is not at the position of the notch 32 , the positioning lever 52 will at most rotate until its left end abuts against the inner wall of the sleeve 3 .

[0043] In particular, by thickening the upper side wall of the positioning lever 52 , the positioning lever 52 is brought into contact with the disk 51 in advance, thereby preventing the left end of the positioning lever 52 from extending out of the sleeve 3 .

[0044] When the positioning lever 52 is in any notch 32 , it functions as a circumferential limiter, thereby keeping the rotating shaft 4 and the clamp 6 fixed.

[0045] When the angle of the clamp 6 needs to be changed, force is applied to the right end of the positioning lever 52 to push the left end thereof to compress the spring 53 and rotate clockwise until the left end completely leaves the notch 32 of the sleeve 3 .

[0046] Then push the positioning lever 52, which in turn drives the disc 51, the shaft 4, the clamp 6 and the parts clamped therein to rotate together. After reaching the required angle, release the positioning lever 52, and the left end of the positioning lever 52 is engaged in the notch 32 under the action of the spring 53 to achieve fixation.

[0047] The clamp 6 is a clamp structure, consisting of a primary half and a secondary half, hinged at the top and bolted together at the bottom. One end of the bolt is hinged to the bottom of the primary half, while the other end is connected to the bottom of the secondary half via a nut. The left end of the shaft 4 is extended into a flange structure, and the right outer wall of the primary half is fixed to the left end of the shaft 4 via multiple hexagon socket head cap screws.

[0048] During use, the lifting lug 1 is suspended from a lifting device, and the fixture 6 holds the shaft part to be processed. The lifting device transports the shaft part to the processing station. By operating the positioning lever 52, the fixture 6 and the shaft part clamped by it can be rotated to meet the processing requirements.

[0049] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
