Abstract
Description
Technical Field
[0001] This utility model belongs to the field of motor shaft processing technology, and in particular relates to motor shaft bracket. Background Technology
[0002] When grinding existing motor shafts (especially H180 and above models), due to the heavy weight of the shafts, a lifting device is required for loading and unloading. However, the lifting device is prone to shaking during use, causing misalignment between the shaft's center hole and the tailstock tip. When the tailstock tip extends, it can easily deviate and damage the shaft's center hole. Furthermore, the operator must simultaneously control the lifting device, the shaft, and the tailstock tip pedal, making the operation difficult and requiring a high degree of coordination.
[0003] During the material unloading stage, it is difficult to precisely control the force applied to the shaft by the lifting device: if the force is too great, the tailstock tip will retract, causing the shaft to lift upwards and scratch the center hole and cross-section of the shaft; if the force is too small, the shaft will sink downwards, easily impacting the tip, damaging both the center hole and the tailstock tip. Furthermore, traditional supports have poor adjustability, failing to flexibly adjust their position according to the shaft's outer diameter and length, making it difficult to adapt to different shaft models. This not only affects processing efficiency but also fails to effectively prevent component damage. Utility Model Content
[0004] This utility model addresses the problems in the prior art by proposing the following technical solution: A motor shaft bracket includes at least two bracket bases. A linearly adjustable support block 1 is installed on the top of the bracket base. A support block 2 is provided on the inner side of the support block 1. At least two guide blocks are fixedly connected to the side wall of the support block 1. A V-shaped groove for preventing the motor shaft from rotating is opened on the top of the support block 2. A guide opening for sliding cooperation with the guide blocks is opened on the support block 2. A height adjustment lifting component is installed on the support block 2.
[0005] As a preferred embodiment of the above technical solution, the top of the bracket base is provided with a dovetail groove, the side wall of the first support block is fixedly connected with a slider that slides in cooperation with the dovetail groove, and the first support block is threadedly connected with a positioning bolt, the tail end of the positioning bolt abutting against the side wall of the bracket base.
[0006] As a preferred embodiment of the above technical solution, an anti-collision sticker is affixed to the surface of the V-groove, and the anti-collision sticker is made of, but is not limited to, nylon material.
[0007] As a preferred embodiment of the above technical solution, the second support block has at least two through holes, and a lifting bolt is installed in the through holes. The lifting bolt is threaded with a nut and a nut, which are located on both sides of the second support block and abut against it.
[0008] The beneficial effects of this utility model are as follows: 1. This utility model, through the combination structure of "at least two support bases + linear adjustment of support block one + height adjustment of support block two", can stably support the motor shaft of H180 and above with heavy self-weight, and prevent the shaft from sinking or tilting due to weight. 2. The sliding fit between support block one and the bracket base, and the guiding fit between support block two and support block one, of this utility model can precisely adjust the position according to the outer diameter and length of the rotating shaft, so that the center hole of the rotating shaft is stably in a state of "slightly lower than the head and tailstock tips"—effectively solving the problem of "deviation between the center hole and tip of the rotating shaft caused by the shaking of the lifting device during loading" in document 2, preventing the tailstock tip from deviating and damaging the center hole when it extends. At the same time, it eliminates the need for the operator to control the lifting device, rotating shaft and tailstock tip pedals simultaneously as in traditional operations, greatly simplifying the operation process, reducing the difficulty of operation, and reducing damage to the center hole of the rotating shaft and tailstock tip caused by operational errors from the root.

[0011] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.
[0012] Example like Figure 1 , Figure 2 and Figure 3 As shown, the motor shaft bracket includes at least two bracket bases 10. A linearly adjustable support block 20 is installed on the top of the bracket base 10. A support block 30 is provided on the inner side of the support block 20. At least two guide blocks 22 are fixedly connected to the side wall of the support block 20. A V-groove 31 for preventing the motor shaft from rotating is opened on the top of the support block 30. A guide opening 32 for sliding cooperation with the guide block 22 is opened on the support block 30. A height adjustment lifting component is installed on the support block 30.
[0013] Specifically, at least two support bases 10 can stably support the rotating shaft (especially suitable for heavy rotating shafts such as H180 and above), preventing the rotating shaft from sinking or tilting due to its weight; The linear adjustment of support block 1 20 and the height adjustment and guiding cooperation of support block 2 30 (guide block 22 and guide opening 32) can accurately adjust the position according to the outer diameter and length of the shaft, so that the center hole of the shaft is slightly lower than the top of the head and tail seats. This effectively solves the problem of deviation between the center hole and the top of the shaft caused by shaking when the lifting device is loading, and prevents the top of the tail seat from deviating and damaging the center hole when it extends out. Meanwhile, the operator does not need to control the lifting device, the rotating shaft, and the tailstock center pedal at the same time, simplifying the operation process and reducing the difficulty of operation; the V-groove 31 can stably limit the rotating shaft, preventing the rotating shaft from shifting before loading, unloading, or processing, and further ensuring the alignment accuracy of the center hole and the center.
[0014] like Figure 1 , Figure 2 and Figure 3 As shown, a dovetail groove is provided on the top of the support base 10, and a slider that slides in cooperation with the dovetail groove is fixedly connected to the side wall of the support block 20. The support block 20 is threadedly connected with a positioning bolt 21, and the tail end of the positioning bolt 21 abuts against the side wall of the support base 10.
[0015] Specifically, the cooperation between the dovetail groove and the slider ensures the stability and trajectory accuracy of the support block 20 during linear adjustment, avoids deviation during adjustment, and ensures the positional accuracy of the support block 30 when it is adjusted with the support block 20, thereby stabilizing the relative position of the center hole of the rotating shaft and the tip. The positioning bolt 21 can be quickly locked after the support block 20 is adjusted into place, preventing the support block 20 from shifting during processing or loading / unloading, thus enabling "continuous processing of the same model of shaft after one adjustment". When changing models, it is only necessary to loosen the positioning bolt 21 and adjust the position of the support block 20, reducing adjustment time and improving processing efficiency.
[0016] like Figure 1 As shown, the surface of the V-groove 31 is covered with an anti-collision sticker, which is made of, but not limited to, nylon material.
[0017] Specifically, anti-collision pads made of materials such as nylon can form a buffer layer to prevent the outer surface of the pivot from making hard contact with the V-groove 31 and causing scratch damage. At the same time, it can increase the friction between the shaft and the V-groove 31, further preventing the shaft from sliding in the V-groove 31 (especially when the lifting device is removed or the tailstock tip extends or retracts), indirectly reducing the misalignment between the center hole and the tip caused by shaft displacement, and helping to reduce the risk of damage to the shaft center hole and the tailstock tip.
[0018] like Figure 1 , Figure 2 and Figure 3As shown, the second support block 30 has at least two through holes, and a lifting bolt 33 is installed in the through holes. The lifting bolt 33 is threadedly connected to a nut 34 and a nut 35. The nut 34 and the nut 35 are located on both sides of the second support block 30 and abut against it.
[0019] Specifically, the lifting assembly consisting of at least two lifting bolts 33 and double nuts (nut one 34 and nut two 35) can precisely adjust the height of the support block two 30, ensuring that the center hole of shafts with different outer diameters can be stably positioned "slightly lower than the head and tailstock tips" after placement; the locking structure of the double nuts can prevent the lifting bolts 33 from loosening due to processing vibration, and avoid the shaft position change caused by the height deviation of the support block two 30 - preventing the shaft from lifting upward when the tailstock tip retracts (avoiding the tip from scratching the center hole and cross-section), and also preventing the shaft from sinking downward (avoiding impact to the tip from damaging the center hole and tailstock tip); Meanwhile, the height adjustment stability eliminates the need for operators to control the force applied to the lifting device; they can simply place the shaft on the support to complete the alignment, further improving loading and unloading efficiency.
[0020] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
