A steering gear support frame is an auxiliary support device used to place the steering gear components. The steering gear column tube is an important component in the automotive steering system. When machining the steering gear column tube, the friction between the cutting tool and the workpiece converts some of the mechanical energy into heat energy, resulting in an increase in temperature.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1 to 7 This utility model provides a technical solution: a steering gear support frame with heat dissipation effect, including a placement box 1 and a support base 2. The placement box 1 is fixedly installed on the top of the support base 2. The placement box 1 is provided with a positioning placement mechanism 3 inside.

[0026] The positioning and placement mechanism 3 includes a support frame body 31, a through groove 32, a cylindrical groove 33, an abutment spring 34, a clamping plate 35, and a friction pad 36. The support frame body 31 is slidably installed inside the placement box 1. The outer side wall of the support frame body 31 is symmetrically provided with limiting T-blocks. The inner side wall of the placement box 1 is correspondingly provided with two sets of limiting T-grooves for sliding installation of the limiting T-blocks. Two through grooves 32 are provided through the top of the support frame body 31, and a cylindrical groove 33 is circumferentially provided through the inner side wall of the support frame body 31 located at the through groove 32. The bottom inner wall of the cylindrical groove 33 is connected to one end of the abutment spring 34.

The clamping plate 35 is set as an obtuse angle structure, and the side outer wall of the clamping plate 35 is set as an arc structure. The clamping plate 35 is set as an obtuse angle structure and its outer wall is set as an arc structure, so that the steering column tube can be more portable when placed in the clamping plate 35. The setting of the friction pad 36 here increases the contact friction between the device and the outer wall of the steering column tube, so that it can be more stably positioned inside the device.

[0027] The spacing adjustment mechanism 4 includes a positioning support frame 41, a drive motor 42, a reciprocating lead screw 43, and a positioning protrusion 44. A "U"-shaped positioning support frame 41 is fixedly installed on the top outer wall of the support base 2. A drive motor 42 is fixedly installed on the top outer wall of the positioning support frame 41. The output end of the drive motor 42 is connected to the top outer wall of the reciprocating lead screw 43. The bottom outer wall of the reciprocating lead screw 43 is rotatably mounted to the bottom inner wall of the positioning support frame 41. A positioning protrusion 44 is installed through the outside of the reciprocating lead screw 43, and the protruding end of the positioning protrusion 44 penetrates one side outer wall of the placement box 1 and connects to the side of the support frame body 31. The outer walls of the bracket are connected to each other. The positioning protrusion 44 is symmetrically provided with limit sliders on both sides of the outer wall near the support frame body 31. The inner side wall of the support frame body 31 is provided with a strip groove for the positioning protrusion 44 to slide. The support frame body 31 is located directly above the bracket 45. The outer side wall of the bracket 45 is connected to the inner side wall of the placement box 1. The top outer wall of the bracket 45 is provided with a cylindrical placement groove that aligns with the through groove 32. The bracket 45 here provides auxiliary support for the bottom of the steering column tube, while the cylindrical placement groove at its top provides limit support for the bottom of the steering column tube.

[0028] The heat dissipation control mechanism 5 includes an axial flow fan 51, a threaded mounting ring 52, a support tube 53, a protective net 54, a positioning T-block 55, a positioning T-slot 56, a support spring 57, a sliding button 58, and a baffle 59. An axial flow fan 51 is installed on the outer side wall of the placement box 1 near the bottom, with the outlet of the axial flow fan 51 facing the inside of the placement box 1. A threaded mounting ring 52 is fixedly installed on the outer wall of the housing of the axial flow fan 51 at the air inlet. A support tube 53 is rotatably installed on the outside of the threaded mounting ring 52, and a corresponding annular threaded groove is provided on the inner side wall of the support tube 53. A protective net 54 is slidably installed inside the support tube 53. A positioning T-block 55 is fixedly installed on one side of the outer wall of the protective net 54, and a corresponding positioning T-slot is provided on the inner side wall of the support tube 53. The positioning T-shaped block 55 is slidably installed in the positioning T-shaped groove 56. A support spring 57 is installed between the outer side wall of the positioning T-shaped block 55 and the inner bottom wall of the positioning T-shaped groove 56. A sliding button 58 is fixedly installed on the other outer wall of the protective net 54, and the sliding end of the sliding button 58 is located outside the support tube 53. A baffle 59 is fixedly installed on the outside of the sliding button 58, and the baffle 59 is slidably connected to the outer side wall of the support tube 53. A strip-shaped groove for sliding installation of the sliding button 58 is correspondingly opened on the outer side wall of the support tube 53. The length of the baffle 59 is greater than the groove length of the strip-shaped groove. This design, where the length of the baffle 59 is greater than the groove length of the strip-shaped groove, ensures that the protective net 54 can effectively block dust, and also prevents dust from outside the device from directly entering the device through the strip-shaped groove.

[0029] Working principle: According to Figures 1 to 7 When the freshly processed steering column tube needs to be placed inside the device, the distance between the support frame body 31 and the bracket 45 needs to be adjusted according to the height of different steering column tube models. During adjustment, the drive motor 42 needs to be turned on. When the drive motor 42 is turned on, it will automatically drive the reciprocating screw 43 to rotate. Due to the design of the limiting sliders on both sides of the positioning protrusion 44 sliding inside the strip groove, the reciprocating screw 43 will only drive the positioning protrusion 44 to achieve vertical sliding trajectory movement when rotating. When the positioning protrusion 44 moves, it will automatically drive the support frame body 31 to move. At this time, the two sets of limiting T-blocks on the side of the support frame body 31 slide inside the limiting T-groove. When the support frame body 31 moves to the appropriate support height, the drive motor 42 can be turned off. It should be noted that the drive motor 42 has a self-locking function. After it is turned off, the support frame body 31 can still maintain the position after the movement.

[0030] The steering column tube is then pushed vertically downwards to the middle position of the three clamping plates 35. The clamping plates 35 are then squeezed by the steering column tube and move to the side to provide a certain space for the placement of the steering column tube. At this time, the contact spring 34 is compressed by the clamping plate 35 and is in a contracted state. At the same time, the contact spring 34 will generate a reaction force when squeezed and push the clamping plate 35 to move in the opposite direction, making it closely contact the outer wall of the steering column tube. The friction pad 36 is designed to increase the contact friction between the device and the outer wall of the steering column tube, so that it can be more stably positioned inside the device. The bracket 45 is designed to provide auxiliary support for the bottom of the steering column tube.

[0031] When it is necessary to cool the steering column tube inside the device, simply turn on the axial fan 51. The axial fan 51 will then cool the steering column tube using air cooling. Refer to the instruction manual for details. Figure 2 As shown, multiple sets of through holes are opened inside the support frame body 31 and the bracket 45 to allow airflow to pass through. This provides a flow channel for the airflow of the axial flow fan 51 while ensuring the normal support and placement function of the support frame body 31 and the bracket 45, so that it can better cool the diverter column tube.

[0032] The protective netting 54 here ensures the normal operation of the axial flow fan 51 and also prevents external dust from entering the device.

[0033] When a lot of impurities accumulate on the outside of the protective net 54 and need to be cleaned, simply rotate the auxiliary support tube 53 to remove it from the outside of the threaded mounting ring 52. Then, move the slide button 58. When the slide button 58 moves, it will automatically drive the positioning T-block 55 to slide inside the positioning T-block 55. At this time, the support spring 57 is compressed by the positioning T-block 55 and is in a contracted state and stores energy accordingly. Then, release the slide button 58, and the reaction force generated by the compression of the support spring 57 will quickly drive the protective net 54 to reset. This vibration process will shake off the impurities accumulated on the outside of the protective net 54. By repeatedly moving the slide button 58 in this way, the cleaning process of the protective net 54 can be completed. The installation is the same after cleaning.

[0034] It should be noted that the aforementioned drive motor 42 and axial flow fan 51 can be powered by existing operating techniques, whether using power supply components or external wires. These are all conventional operating techniques and will not be described in detail here. The above is the working process of the entire device. Any content not described in detail in this specification belongs to the prior art known to those skilled in the art.

[0035] 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.
