Technical Field
[0001] This utility model relates to the field of lead screw support technology, specifically a quick-assembly lead screw support. Background Technology
[0002] The lead screw support is a key component in a mechanical transmission system used to fix and support ball screws or trapezoidal lead screws. Through its cooperation with the end of the lead screw, it achieves axial and radial positioning of the lead screw. During the transmission process, it must not only bear the radial load and axial thrust generated when the lead screw rotates, but also ensure the rotation accuracy of the lead screw and reduce transmission errors caused by vibration or offset. Its structural design needs to meet the requirements of high-precision assembly. The bearing housing is mostly made of cast iron or aluminum alloy. In some high-precision scenarios, steel is used and heat-treated to improve rigidity and wear resistance. Reasonable selection and installation of lead screw support can effectively extend the service life of the lead screw, ensure the stable operation and motion accuracy of the mechanical system, and is an indispensable supporting component in the precision transmission system. Currently, most lead screw support seats are integrated units. When it is necessary to replace the bearing or clean the inside, the entire lead screw must be pulled out or the entire support seat must be removed. This results in high maintenance costs and long maintenance time. Furthermore, due to its integrated structure, if any part is damaged, the entire unit must be replaced or returned to the factory for repair, which is costly. Therefore, a quick-assembly lead screw support seat is proposed to address the above problems. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0015] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0016] Please see Figures 1-7 This utility model provides a technical solution: A quick-assembly type lead screw support includes a fixed seat 1 and a movable seat 2. A bearing cover 3 is provided on the front side of the fixed seat 1 and the movable seat 2. A positioning component 4 is provided between the fixed seat 1 and the movable seat 2. An assembly component 5 is provided between the positioning component 4 and the rear wall of the fixed seat 1. The positioning component 4 includes a positioning groove 41 and a positioning slide 42. The positioning groove 41 is symmetrically opened on the top two sides of the fixed seat 1, and the rear end of the positioning groove 41 penetrates the rear wall of the fixed seat 1. The positioning slide 42 is fixedly connected to the bottom two sides of the movable seat 2, and the length of the positioning slide 42 is the same as that of the positioning groove 41.
[0017] As a further implementation of this solution, both the positioning slide 41 and the positioning slide 42 are T-shaped, and the positioning slide 41 and the positioning slide 42 are positioned correspondingly and matched in specifications. In the above configuration, the positioning slide 41 and the positioning slide 42 are both T-shaped, which not only facilitates the cooperation between the positioning slide 41 and the positioning slide 42, but also avoids vertical movement.
[0018] As a further implementation of this solution, the inner sidewall of the positioning groove 41 is provided with a plurality of sliding balls 43 arranged at equal intervals, and the two sidewalls of the positioning strip 42 are symmetrically provided with sliding grooves 44. The sliding grooves 44 are adapted to the sliding balls 43. In the above arrangement, the cooperation between the sliding balls 43 and the sliding grooves 44 can reduce the sliding friction between the positioning groove 41 and the positioning strip 42, so as to improve the smoothness between the positioning groove 41 and the positioning strip 42.
[0019] As a further implementation of this solution, the assembly component 5 includes an assembly support plate 51 fixedly connected to the rear end of the positioning slide bar 42. The front sides of the assembly support plate 51 are symmetrically and fixedly connected with positioning springs 52. The inner side of the positioning springs 52 is fixedly connected with a return spring 53. The rear wall of the fixed seat 1 is symmetrically provided with multiple positioning slots 54. The number of positioning slots 54 and the positioning springs 52 are equal, their positions are corresponding and their specifications are matched. An assembly bolt 55 passes through the center of the rear end of the assembly support plate 51. The rear end of the fixed seat 1 is provided with an assembly screw hole 56 that corresponds to the position of the assembly bolt 55 and matches its specifications. In the above configuration, after the initial combination between the fixed seat 1 and the movable seat 2, the combination strength between the fixed seat 1 and the movable seat 2 can be strengthened to ensure the overall connection strength of the complete support.
[0020] As a further implementation of this solution, mounting bolts 6 are inserted through the four corners of the bearing cover 3. Mounting screw holes 7 are provided on both sides of the front wall of the fixed seat 1 and both sides of the front wall of the movable seat 2. The mounting screw holes 7 and the mounting bolts 6 are positioned correspondingly and matched in specifications. In the above configuration, when the fixed seat 1 and the movable seat 2 are combined to form a complete support seat, the bearing cover 3 can be installed on the front side of the support seat by using the mounting bolts 6 and the mounting screw holes 7.
[0021] Workflow: First, the fixed seat 1 and the movable seat 2 need to be initially assembled using the positioning component 4. During the initial assembly, the movable seat 2 is first placed above and behind the fixed seat 1, and the front end of the positioning slide bar 42 at the bottom of the movable seat 2 slides into the rear end of the positioning groove 41 opened at the top of the fixed seat 1. Then, the movable seat 2 is moved forward. During this period, the sliding ball 43 will cooperate with the sliding groove 44 to reduce the sliding friction between the positioning groove 41 and the positioning slide bar 42, so as to improve the smoothness between the positioning groove 41 and the positioning slide bar 42. After the front end of the positioning slide bar 42 slides to the front end of the positioning groove 41, the movable seat 2 will be aligned with the corner of the fixed seat 1, and the initial assembly is completed. After the initial assembly, the assembly component 5 is used to strengthen the combination strength between the fixed seat 1 and the movable seat 2 to ensure the overall connection strength of the complete support. In the final stage of the positioning slide 42 moving forward in the positioning groove 41, the front end of the assembly support plate 51 will fit against the rear end of the fixed seat 1. At the same time, the positioning spring 52 will be inserted into the positioning slot 54 opened at the corresponding position at the rear end of the fixed seat 1. When inserted, the inner wall of the positioning slot 54 will squeeze the positioning spring 52. After being squeezed, the positioning spring 52 will retract inward and squeeze the return spring 53 at the same time. The return spring 53 will drive the positioning spring 52 to return and expand outward through its own rebound force, so that the positioning spring 52 will be stably locked in the positioning slot 54. At the same time, the hole of the mounting bolt 55 on the assembly support plate 51 corresponds to the mounting screw hole 56. Finally, the mounting bolt 55 is screwed into the mounting screw hole 56. After the fixed seat 1 and the movable seat 2 are combined by the positioning component 4 and the assembly component 5 to form a complete support seat, the bearing cover 3 is placed on the front side of the support seat, and the hole positions of the mounting bolts 6 correspond to the positions of the mounting screw holes 7. Finally, the mounting bolts 6 are screwed into the corresponding mounting screw holes 7 one by one, thereby installing the bearing cover 3 on the front side of the support seat.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
