Description

Technical Field

[0001] The utility model relates to the technical field of workpiece connection, in particular to a multifunctional tensioning block. Background Art

[0002] In the production process of industrial furnaces, electric motors are often used as driving devices. At present, most traditional motors use a base made of cast iron or aluminum alloy to fix the motor. When the motor is in use, a pulley is installed at the motor output end, which is connected to the rotating shaft of the external machine through a belt drive. Therefore, during use, in order to prevent the motor from being forced to deviate and approach the external machine, a tension block is often used to abut the motor base to improve the stability of the motor.

[0003] Existing tensioning blocks mainly fix components by tightening nuts, but their fixing height and position are usually fixed, which makes it difficult to adapt to components with various base thicknesses. This limits the scope of application of existing tensioning blocks. It is necessary to develop tensioning blocks with various fixed heights according to the design of different bases. Therefore, there is an urgent need for a tensioning block that can be flexibly adjusted according to components with different base thicknesses to improve its functionality and scope of application. Utility Model Content

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a multifunctional tensioning block to solve the above problems.

[0005] The purpose of the present utility model is achieved as follows: a multifunctional tensioning block, comprising a rectangular tensioning block body, the tensioning block body is provided with a threaded hole, the threaded hole is located in an eccentric position of the tensioning block body, and a positioning bolt is threadedly connected to the threaded hole.

[0006] Preferably, a reinforcing component for improving the internal structural strength of the tension block is provided inside the tension block body.

[0007] Preferably, the reinforcing component includes a mounting groove, and the mounting groove includes a straight mounting portion and an arc-shaped mounting portion. A first short reinforcing rib is provided in the straight mounting portion, and a second short reinforcing rib is provided in the arc-shaped mounting portion.

[0008] Preferably, the second short reinforcing ribs are arranged at an angle, and the angle between the second short reinforcing ribs and the horizontal plane is 45°.

[0009] Preferably, a carburized layer is provided on the exterior of the front and rear side surfaces of the tension block body.

[0010] Preferably, a transition fillet is provided at the connection between the bolt head and the threaded hole of the positioning bolt.

[0011] The utility model has the following beneficial effects:

[0012] 1. The multifunctional tensioning block comprises a rectangular tensioning block body, which is provided with a threaded hole extending therethrough. The threaded hole is located at an eccentric position of the tensioning block body, and a positioning bolt is connected to the threaded hole. In actual use, the tensioning block can be adjusted according to the thickness of the base of the tightened component as needed, that is, the height or position of the threaded hole from the bottom surface is changed so that the positioning bolt is located at a suitable position at the tightening position, thereby improving the functionality and applicability of the tensioning block body.

[0013] 2. A reinforcement component for improving the internal structural strength of the tension block is provided inside the tension block body. The reinforcement component can improve the stability and bending toughness of the tension block body, thereby ensuring a longer service life and higher reliability. The reinforcement component includes a mounting groove, and the mounting groove includes a straight mounting portion and an arc-shaped mounting portion. The straight mounting portion is provided with a first reinforcing short rib, and the arc-shaped mounting portion is provided with a second reinforcing short rib. By cleverly superimposing the straight mounting portion and the arc-shaped mounting portion at the mounting groove, the design not only takes into account the vertical alignment and fixation requirements, but also optimizes the protection in the bending or stress concentration area, enhances the comprehensive tensile, compressive and fatigue resistance of the tension block body, and maximizes the durability and service life of the entire tension block body.

[0014] 3. The connection between the bolt head and the threaded hole of the positioning bolt is provided with a transition fillet. The transition fillet can effectively avoid the stress concentration caused by sharp edges, significantly improving the fatigue resistance and service life of the bolt structure. At the same time, it also reduces the risk of fracture when subjected to cyclic loads. This design makes the contact between the bolt and the threaded hole smoother and more fluent, and also improves the accuracy and stability of the bolt positioning, thereby improving the efficiency and reliability of the overall assembly.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the technical solutions in the specific implementation methods of the present invention are clearly and completely described below to further illustrate the present invention. Obviously, the specific implementation methods described are only part of the implementation methods of the present invention, rather than all styles.

[0022] The following is combined with Figure 1-3 The utility model is described in further detail.

[0023] Example 1:

[0024] A multifunctional tensioning block comprises a rectangular tensioning block body 1, the tensioning block body 1 having a length of 70 mm, a width of 55 mm, and a thickness of 25 mm. The tensioning block body 1 is provided with a threaded hole 2 which is located at an eccentric position of the tensioning block body 1. A positioning bolt 3 is connected to the inner thread of the threaded hole 2. The size of the positioning bolt 3 adapted to the threaded hole 2 is M20. In actual use, the tensioning block can be adjusted according to the thickness of the base of the tightened component as needed, that is, the fixing direction can be reversed, and the height or position of the threaded hole 2 from the bottom surface can be changed to adapt to the positioning of motors and reducers with different bases so that the positioning bolt 3 is located at a suitable position at the tightening position, thereby improving the functionality and applicability of the tensioning block body 1.

[0025] like Figure 1 The tensioning block body is used to adapt to our company's three different sizes of motors. When using the tensioning block body 1, when a small motor is selected, the lower side of the tensioning block body 1 abuts the upper surface of the operating table. When a medium-sized motor is selected, the fixing direction is reversed so that the left side of the tensioning block body 1 abuts the upper surface of the operating table. When a large motor is selected, the fixing direction is reversed again so that the upper side of the tensioning block body 1 abuts the upper surface of the operating table. According to the different models of each motor, the tensioning block body 1 is fixed and installed in different directions so that the positioning bolt 3 presses the middle force position of the motor base, so that each model of motor can maintain stability and adaptability during operation.

[0026] In this embodiment, a reinforcement component is provided within the tension block body 1 for increasing the internal structural strength of the tension block body 1. This reinforcement component can improve the stability and bending toughness of the tension block body 1, thereby ensuring a longer service life and higher reliability. The reinforcement component includes a mounting slot 41, which includes a linear mounting portion 411 and an arcuate mounting portion 412. A first reinforcing rib 42 is provided within the linear mounting portion 411, and a second reinforcing rib 43 is provided within the arcuate mounting portion. By cleverly superimposing the linear mounting portion 411 and the arcuate mounting portion 412 at the mounting slot 41, this design not only takes into account the requirements for vertical alignment and fixation, but also optimizes protection in areas of bending or stress concentration. The first reinforcing rib 42 installed within the linear mounting portion 411 serves as a foundation reinforcement, providing significant vertical reinforcement, ensuring uniformity and stability of load bearing, and reducing the possibility of deformation of the tension block body 1 when subjected to axial force. The design of the second reinforcing short ribs 43 of the arc-shaped mounting portion 412 focuses on optimizing the structural strength and flexibility of the curved surface contact point, resisting cracks or damage that may be caused by bending stress, enhancing the comprehensive tensile, compressive and fatigue resistance of the tension block body 1, and maximizing the durability and service life of the entire tension block body 1.

[0027] In this embodiment, the second short reinforcing ribs 43 are inclined at a 45° angle to the horizontal. This angle design significantly improves the stability and bearing capacity of the structure. The 45° inclination effectively disperses the external forces acting on the second short reinforcing ribs 43, distributing them more evenly, thereby reducing stress concentration, significantly enhancing the overall structural resistance, and preventing localized damage caused by stress concentration. This angle optimization not only enhances the structure's ability to withstand external vibration and impact, but also improves material utilization, reduces the amount of reinforcing ribs used, and saves costs.

[0028] In this embodiment, a carburized layer 5 is provided on the exterior of the front and rear side surfaces of the tension block body 1. Through the carburizing treatment, not only the interaction performance between the tension block body 1 and the contact surface is enhanced, but also the wear during long-term work is effectively resisted, thereby extending the service life of the tension block body 1.

[0029] In this embodiment, a transition fillet 6 is provided at the connection between the bolt head of the positioning bolt 3 and the threaded hole 2. The transition fillet 6 can effectively avoid the stress concentration phenomenon caused by sharp edges, significantly improve the fatigue resistance and service life of the bolt structure, and at the same time, reduce the risk of fracture when subjected to cyclic loads. This design makes the contact between the bolt and the threaded hole 2 smoother and more fluent, and also improves the accuracy and stability of the bolt positioning, thereby improving the efficiency and reliability of the overall assembly.

[0030] The working principle of the present utility model is as follows: the multifunctional tensioning block comprises a rectangular tensioning block body 1, the tensioning block body 1 is 70mm long, 55mm wide and 25mm thick, the tensioning block body 1 is provided with a threaded hole 2 which is located at an eccentric position of the tensioning block body 1, the threaded hole 2 is internally threadedly connected with a positioning bolt 3, the threaded hole 2 is adapted to the positioning bolt 3 with a size of M20, and in actual use, it can be adjusted according to the thickness of the base of the tightened parts as needed, that is, the fixing direction is reversed, the height or position of the threaded hole 2 from the bottom surface is changed, so as to adapt to the positioning of motors and reducers with different bases so that the positioning bolt 3 is located at a suitable position at the tightening position, thereby improving The functionality and scope of application of the tension block body 1; a reinforcement component for improving the internal structural strength of the tension block is provided inside the tension block body 1. The reinforcement component can improve the stability and bending toughness of the tension block body 1, thereby ensuring a longer service life and higher reliability. The reinforcement component includes a mounting groove 41, and the mounting groove 41 includes a straight mounting portion 411 and an arc-shaped mounting portion 412. A first reinforcing short rib 42 is provided in the straight mounting portion 411, and a second reinforcing short rib 43 is provided in the arc-shaped mounting portion. By cleverly superimposing the straight mounting portion 411 and the arc-shaped mounting portion 412 at the mounting groove 41, this design not only takes into account the requirements of vertical alignment and fixation, but also optimizes protection in bending or stress concentration areas. The first reinforcing short rib 42 installed in the straight mounting portion 411 plays a basic reinforcement role, providing significant vertical reinforcement, ensuring the uniformity and stability of the load, and reducing the possibility of deformation of the tension block body 1 when subjected to axial force. The design of the second reinforcing short rib 43 of the arc-shaped mounting portion 412 focuses on optimizing the structural strength and flexibility of the curved surface contact point, resisting cracks or damage that may be caused by bending stress, enhancing the comprehensive tensile, compressive and fatigue resistance of the tensioning block body 1, and maximizing the durability and service life of the entire tensioning block body 1; the connection between the bolt head of the positioning bolt 3 and the threaded hole 2 is provided with a transition fillet 6, which can effectively avoid the stress concentration caused by sharp edges, significantly improve the fatigue resistance and service life of the bolt structure, and at the same time, reduce the risk of fracture when subjected to cyclic loads. This design makes the contact between the bolt and the threaded hole 2 smoother and more fluent, and also improves the accuracy and stability of the bolt positioning, thereby improving the efficiency and reliability of the overall assembly.
