Description

Technical Field

[0001] This invention relates to the field of tooling technology, and in particular to a precision positioning and adjustment tooling for a speed reducer. Background Technology

[0002] Currently, during shipbuilding, when installing a speed reducer, the position of the speed reducer on the base is first roughly adjusted. After this adjustment, set screw plates are welded directly to the base in the forward, backward, left, and right directions of the speed reducer. The speed reducer is then moved using the set screws, and the installation position is repeatedly fine-tuned to ensure the coaxiality of the speed reducer's output shaft with the corresponding transmission components. However, the high temperature during the welding of the set screw plates can easily cause slight deformation of the base, rendering the rough adjustment ineffective and requiring a second rough adjustment, which affects work efficiency. Furthermore, after the set screw plates are removed, the damaged paint on the base needs to be repaired, increasing additional production costs. In addition, the set screws can also damage the external paint of the speed reducer. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the purpose of this invention is to provide a gearbox precision positioning and adjustment fixture that can improve work efficiency, avoid increasing additional production costs, and prevent damage to the paint on the outside of the gearbox.

[0004] To achieve the above objectives, the technical solution adopted by the precision positioning and adjustment tooling for the speed reducer of the present invention is as follows:

[0005] A precision positioning and adjustment fixture for a speed reducer includes a set screw plate. The bottom of the set screw plate has a slot for engaging with the edge of a base. Several locking bolts are threaded onto the side wall of the slot to temporarily fix the set screw plate to the edge of the base. A first set screw is threaded onto the middle of the set screw plate, and a second set screw is threaded onto the top of the set screw plate. The axes of the first and second set screws are perpendicular to each other, and protective heads are provided at the ends of the first and second set screws.

[0006] Preferably, both the first set screw and the second set screw are fully threaded bolts.

[0007] Preferably, the protective head includes a connecting seat, one end of which is fixed to a fully threaded bolt, and the other end is provided with a ball socket seat, a universal ball is provided inside the ball socket seat, and a top plate is provided at one end of the universal ball extending out of the ball socket seat.

[0008] Preferably, a damping silicone sleeve is provided between the inner wall of the ball socket and the outer wall of the universal ball, and a limiting plate is provided at the bottom of the ball socket to prevent the damping silicone sleeve from falling off.

[0009] Preferably, the top surface of the set screw plate has a notch, so that a boss is formed on one side of the top surface of the set screw plate, and the second set screw is threaded to the middle of the boss.

[0010] Preferably, the bottom surface of the notch is an inclined surface extending toward the closed end of the slot.

[0011] Preferably, a locking nut is threaded onto the locking bolt.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] 1. The set screw plate is attached to the edge of the base by a slot and then temporarily secured by a locking bolt. No welding is required, the base will not be slightly deformed, and it will not affect the previous coarse adjustment and positioning of the reducer. No secondary coarse adjustment is required, which improves work efficiency. The set screw plate can be removed by loosening the locking bolt. No fire cutting is required, and the paint on the base will not be damaged. This saves the work of grinding and repainting, and saves production costs.

[0014] 2. Both the first and second set screws are set on the same set screw plate, which has a two-way fine adjustment function, reducing the number of set screw plates required and improving work efficiency.

[0015] 3. The position of the set screw plate on the base can be flexibly adjusted as needed to facilitate quick alignment of the coaxiality between the reducer output shaft and the corresponding transmission components; if misalignment occurs during equipment operation, it can also be finely adjusted and corrected at any time using this tooling, making it convenient to use; it can also be used in similar equipment installation scenarios, and has a certain degree of versatility.

[0016] 4. Protective heads are installed at the ends of the first and second setter screws to prevent mutual wear between the first and second setter screws and the reducer, and to avoid damaging the external paint of the reducer. Attached Figure Description

[0025] The present invention will be further illustrated below with reference to the accompanying drawings and specific embodiments. It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of the invention. After reading this invention, any modifications of the invention in various equivalent forms by those skilled in the art will fall within the scope defined by the appended claims.

[0026] like Figure 1-7 As shown, a precision positioning and adjustment fixture for a speed reducer includes a set screw plate 1. The bottom of the set screw plate 1 has a slot 11 for engaging with the edge of a base 2. Two locking bolts 3 are threaded onto the side wall of the slot 11 to temporarily fix the set screw plate 1 to the edge of the base 2. Locking nuts 4 are threaded onto the locking bolts 3 to prevent loosening and improve the reliability of the temporary fixation of the set screw plate 1. A first set screw 5 is threaded onto the middle of the set screw plate 1. A notch 12 is formed on the top surface of the set screw plate 1, creating a relatively narrow boss 13 on the side of the top surface of the set screw plate 1 opposite to the closed end of the slot 11. A second set screw 6 is threaded onto the middle of the boss 13. The axes of the first set screw 5 and the second set screw 6 are perpendicular to each other, enabling bidirectional adjustment. The notch 12 is created to shorten the length of the second set screw 6. The bottom surface of the notch 12 faces the closed end of the slot 11. An extended bevel removes unnecessary parts of the set screw plate 1 to reduce its weight and facilitate handling. The first set screw 5 and the second set screw 6 are both fully threaded bolts. A protective head 7 is installed at the end of the fully threaded bolt. The protective head 7 includes a connecting seat 71. The rear end of the connecting seat 71 is fixed to the fully threaded bolt (the thread of the fully threaded bolt can be used for fixing). A ball socket seat 72 is installed at the front end of the connecting seat 71. A universal ball 73 is installed inside the ball socket seat 72. A top plate 74 is installed at the end of the universal ball 73 that extends out of the ball socket seat 72. A damping silicone sleeve 75 is installed between the inner wall of the ball socket seat 72 and the outer wall of the universal ball 73. A limiting plate 76 is installed at the bottom of the ball socket seat 72 to prevent the damping silicone sleeve 75 from falling off. The damping silicone sleeve 75 can keep the top plate 74 roughly aligned with the reducer. During operation, there is no need to manually adjust the orientation of the limiting plate 76, avoiding hand injuries.

[0027] The specific working process and principle of this invention: After the installation position of the reducer is roughly adjusted, the set screw plate 1 is snapped onto the edge of the base 2, and the locking bolts 3 and locking nuts 4 are tightened in sequence to ensure that the set screw plate 1 is firm and reliable. The top plate 74 at the end of the first set screw 5 is rotated so that it is roughly aligned with the mounting foot 8 of the reducer. The top plate 74 at the end of the second set screw 6 is rotated so that it is roughly aligned with the housing 9 of the reducer. At this time, the installation position of the reducer can be finely adjusted by turning the first set screw 5 or the second set screw 6. During the screwing process, the first set screw 5 or the second set screw 6 drives the connecting seat 71 and the ball socket seat 72 to rotate. The top plate 74 and the universal ball 73 are subjected to force and undergo slight deflection with the mounting foot 8 or the housing 9 of the reducer. This will not damage the paint on the outside of the reducer, and there is no need to touch up the paint.
