Description

Technical Field

[0001] The utility model belongs to the technical field of forklift drive axles, and in particular relates to a rotary tooling for a forklift drive axle. Background Art

[0002] A forklift drive axle is a component of a forklift. Its main structure consists of a drive axle housing and a reducer mounted within it. The drive axle allows for speed adjustment and changes in torque transmission direction during operation.

[0003] The shape of the drive axle housing is an irregular structure. The horizontal projection of the center part of the housing is a circular structure, and the two ends are integrally formed into a cylindrical structure. The transmission structure such as the rotating shaft passes through the cylindrical cavity of the cylindrical structure, while the transmission structure such as the gear is installed in the center part of the housing (that is, the drive axle housing part).

[0004] During the production of the drive axle housing, various processes are required, including welding, drilling mounting holes, and polishing. Therefore, the heavy drive axle housing needs to be locked during processing. Specifically, the housing blank must be locked after hoisting. However, current locking fixtures can only lock a fixed-size blank at a time. This is mainly due to the fixture's main structure consisting of a horizontal fixture base, on which a locking device such as a pressure plate is installed.

[0005] The above defects result in the following problems in the actual working process: firstly, the bulky drive axle housing needs to be repeatedly loaded, locked, and unloaded during the processing, so the working efficiency during the processing is too low and the working labor is too large; secondly, if the angle of the drive axle housing needs to be adjusted during welding during the processing, the locking structure can only be loosened, and then the housing needs to be hoisted and unloaded again and then locked again.

[0006] Therefore, the huge defects of the entire tooling are: low flexibility, low processing efficiency, and excessive workload. The above defects are the reasons for the low processing efficiency and excessive processing workload during the processing of the drive axle housing. Utility Model Content

[0007] Based on the above background, the purpose of the present invention is to provide a forklift drive axle rotating tooling.

[0008] In order to achieve the above objectives, the present invention adopts the following technical solutions:

[0009] A forklift drive axle rotary fixture comprises a rotary fixture shaft, wherein the rotary fixture shaft is equipped with a plurality of locking mechanisms for locking a drive axle housing, and the drive axle housing is locked on adjacent locking mechanisms;

[0010] The locking mechanism includes a locking seat that is adjustable on the rotating tooling shaft, a plurality of inner lap grooves are formed on the outer wall of the locking seat, and the locking mechanism also includes a plurality of outer arc-shaped clamping seats corresponding to the inner lap grooves, and the two ends of the drive axle housing are locked between the inner lap grooves and the outer arc-shaped clamping seats;

[0011] The forklift drive axle rotating tool also includes a plurality of pressing components for pressing against the lute holes on the drive axle housing;

[0012] The tightening assembly includes a butt head, which is installed on the rotating tooling shaft through a height adjustment structure and is arranged between adjacent locking mechanisms.

[0013] Preferably, both ends of the outer arc-shaped holder are respectively mounted on the locking seat through locking screws.

[0014] Preferably, both ends of the groove of the inner material groove are integrally formed with horizontal parts, the locking screw is fixedly connected to the horizontal part, the locking screw passes through the outer arc-shaped seat, and the locking screw is threadedly connected with a locking nut.

[0015] Preferably, a sliding adjustment opening is provided at the center of the lock mounting seat, and sliding adjustment structures are fixedly connected to both sides of the sliding adjustment opening, so that the position of the lock mounting seat on the rotating tooling shaft can be adjusted through the sliding adjustment structures.

[0016] Preferably, the sliding adjustment structure comprises a sliding sleeve welded on the opening of the sliding adjustment port, and the sliding sleeve is threadedly connected with a plurality of tightening screws for tightening against the rotating tooling shaft.

[0017] Preferably, the abutment head is hemispherical in shape, and a hemispherical cavity is provided on the abutment head.

[0018] Preferably, the height adjustment structure includes a threaded seat welded on the rotating tooling shaft, an adjusting screw is threadedly connected to the threaded seat, and the adjusting screw is fixedly connected to the inner cavity wall of the hemispherical cavity.

[0019] Preferably, a hexagonal convex ridge structure is integrally formed on the adjusting screw.

[0020] Preferably, both ends of the rotating tooling shaft are respectively provided with rotating shafts through flanges, the rotating shafts are rotatably connected to a frame, and a driving motor is installed on the rotating shafts.

[0021] The utility model has the following beneficial effects:

[0022] 1. During the working process, after completing one blank, the machine rotates and switches to another blank for processing again, repeating this process to process multiple blank shells at once. All blanks can then be unloaded at once. This method greatly increases processing efficiency and reduces labor during the processing process. The simple locking method and high locking stability further improve processing efficiency.

[0023] 2. The working process is realized by the above-mentioned adjustment structure, and the spacing can be adjusted according to the total length of the drive axle housing. On the one hand, it can meet the processing of workpieces of different specifications and sizes. On the other hand, during the adjustment process, it only needs to loosen the tightening screw to adjust. At the same time, it slides in the form of a sliding sleeve, and the sliding stability is higher.

[0024] 3. The abutment head contacts the center of the drive axle housing (i.e., the mouth of the drive axle housing). Since the shape of the abutment head is hemispherical, which corresponds to the shape of the mouth of the drive axle housing, the abutment head is supported on the mouth of the drive axle housing. In this way, the support is achieved at the center of the drive axle housing, thereby increasing the locking stability of the drive axle housing during rotation and the stability during rotation switching.

[0034] Example 1

[0035] like Figure 1-4 As shown, a forklift drive axle rotating tooling includes a rotating tooling shaft 1. According to the conventional method disclosed in the prior art, a rotating shaft 31 is installed at both ends of the rotating tooling shaft 1 through a flange 3, and the rotating shaft 31 is rotatably connected to a frame (not shown in the figure). A driving motor is installed on the rotating shaft 31, such as being installed on the output shaft of the motor through a coupling (not shown in the figure). During operation, the rotating tooling shaft 1 rotates under the drive of the driving motor.

[0036] The rotary tooling shaft 1 is equipped with a plurality of locking mechanisms for locking the drive axle housing, and the drive axle housing is locked on adjacent locking mechanisms. That is, a pair of adjacent locking mechanisms locks and installs a plurality of drive axle housings.

[0037] The specific structure of the locking mechanism is as follows:

[0038] The locking mechanism includes a locking seat 21 with an adjustable position on the rotating tooling shaft 1, and a plurality of arc-shaped inner loading grooves 22 are provided on the outer wall of the locking seat 21. Correspondingly, the locking mechanism also includes a plurality of outer arc-shaped clamping seats 23 corresponding to the inner loading grooves 22, and the two ends of the drive axle housing are locked between the inner loading grooves 22 and the outer arc-shaped clamping seats 23.

[0039] Specifically, the two ends (horizontally protruding) of the outer arc-shaped holder 23 are respectively installed on the locking seat 21 through locking screws. Correspondingly, the two ends of the groove of the inner material groove 22 are integrally formed with horizontal parts A, and the locking screws are fixedly connected to the horizontal parts A. The locking screw passes through the outer arc-shaped holder 23, and the locking screw is threadedly connected to a locking nut.

[0040] During the work process, the operator uses a lifting hoist to lift the heavy drive axle housing. Before lifting, the distance between the adjacent locking seats 21 is adjusted, and the cylindrical parts at both ends of the drive axle housing are placed on the inner loading groove 22, and then locked through the outer arc-shaped clamping seat 23. The motor is turned on to drive the rotation to the idle inner loading groove 22 on the other side and flip it to the top position. After locking, repeat the operation to achieve the locking of multiple drive axle housing shells after loading.

[0041] So repeatedly, each pair of lock mounting seat 21 is loaded. In this way, a plurality of axle housings to be processed are loaded and locked in the working process at one time.

[0042] Processing after locking is completed, such as hole opening, grinding to remove burrs, welding, etc.

[0043] After one blank is processed, it is rotated and switched to another blank for processing again. This process is repeated to process multiple blank shells at one time. Then all blanks are cut at one time.

[0044] The above method greatly increases the processing efficiency and reduces the labor workload during the processing. In addition, the above locking method is simple and the locking stability is high, which further improves the processing efficiency.

[0045] Example 2

[0046] like Figure 1-4 As shown, based on the structure of Example 1, this embodiment has a sliding adjustment opening at the center of the lock mounting seat 21, and sliding adjustment structures are fixedly connected to both sides of the sliding adjustment opening. The position of the lock mounting seat 21 on the rotating tooling shaft 1 can be adjusted through the sliding adjustment structure.

[0047] The sliding adjustment structure includes a sliding sleeve 24 welded on the sliding adjustment opening. The sliding sleeve 24 is threadedly connected with a plurality of tightening screws 241 for tightening against the rotating tooling shaft 1.

[0048] The working process is realized by the above-mentioned adjustment structure, and the spacing can be adjusted according to the total length of the drive axle housing. On the one hand, it can meet the processing of workpieces of different specifications and sizes. On the other hand, during the adjustment process, it only needs to loosen the tightening screw to adjust. At the same time, sliding in the form of a sleeve 24 has higher sliding stability.

[0049] At the same time, after loosening the locking screw, the locking seat 21 can be flipped, and the workpiece positioned on the locking seat 21 can be flipped synchronously to adjust the angle of the shell blank. In addition, the angle adjustment method driven by the drive motor and the switching of the blank further reduce the processing difficulty. For example, during welding, it is necessary to switch a difficult welding position to a convenient spatial position by rotating the angle adjustment method.

[0050] Example 3

[0051] like Figure 1-4 As shown, based on the structure of Example 2, the forklift drive axle rotating fixture of this embodiment further includes a plurality of tightening components 4 for tightening in the pipa holes on the drive axle housing; the tightening components 4 include a butt 43, which is mounted on the rotating fixture shaft 1 through a height adjustment structure, and the butt 43 is arranged between adjacent locking mechanisms.

[0052] Specifically, the butt 43 is hemispherical in shape and has a hemispherical cavity formed therein. During operation, after the drive axle housing is loaded, the butt 43 abuts against the center of the drive axle housing (i.e., the mouth of the drive axle housing). Because the hemispherical shape of the butt 43 corresponds to the shape of the mouth of the drive axle housing, the butt 43 abuts against the mouth of the drive axle housing, thereby supporting the center of the drive axle housing. This increases the locking stability of the drive axle housing during rotation and the stability during rotation switching.

[0053] The height adjustment structure comprises a threaded seat 41 welded to the rotary tooling shaft 1, on which an adjustment screw 42 is threadedly connected. The adjustment screw 42 is fixedly connected to the inner wall of the hemispherical cavity. The adjustment screw 42 is integrally formed with a hexagonal convex structure.

[0054] During operation, the operator uses a tool such as a wrench to rotate the adjusting screw 42 until the abutment 43 extends outward and contacts the mouth of the axle housing to be driven. Because the abutment 43 is hemispherical, it can fit into the circular mouth of the axle housing (the abutment 43 partially penetrates into the mouth of the axle housing until the mouth of the axle housing contacts the inner end of the abutment 43). The projected shape of the abutment 43 is circular, with a radius greater than the radius of the projected circular shape of the mouth of the axle housing.

[0055] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the present invention should also fall within the scope of protection of the present invention.
