[0019] Beneficial effects of the present invention:

[0020] 1. By setting the limiter, when the press-fitting equipment is installing the shock-absorbing rubber parts for the automobile steering system, an installation guide structure can be formed between the steering gear housing and the shock-absorbing rubber parts to avoid the dislocation and rebound of the shock-absorbing rubber parts during press-fitting, thereby improving the press-fitting effect;

[0021] During operation, the setting of the limit piece can be used to limit and connect the rubber sleeve and the metal sleeve when the shock-absorbing rubber piece is pressed and installed. The rubber sleeve is sleeved on the inner side of the limit piece, and the shock-absorbing rubber piece is squeezed from top to bottom by the press fitter, so that the rubber sleeve and the metal sleeve are pressed and installed into the steering gear housing installed with the limit base.

During installation, the lower end of the limit sleeve is aligned with the mounting hole of the steering gear housing, and the shock-absorbing rubber piece to be installed is placed inside the limit sleeve. The two sides of the shock-absorbing rubber piece are limited and fixed by the movable clamp block. The movable clamp block uses the V-shaped structure to make the movable clamp block When the movable clamp is in contact with the shock-absorbing rubber part, a two-point docking structure is formed. With the setting of the two groups of mobile clamps, the four-point limit fixation of the shock-absorbing rubber part is completed, and the fixing effect of the limit part on the shock-absorbing rubber part is improved. Secondly, the inclined top head of the inclined V-shaped structure can be used to guide the pressing head structure of the press to between the two groups of mobile clamps to avoid the pressing head of the press getting stuck on the outside of the mobile clamps. The setting of several groups of transverse rollers can reduce the friction between the rubber sleeve and the two groups of mobile clamps. When the press moves downward, the shock-absorbing rubber part is guided and fixed by the mobile clamp to avoid bending or rebound of the shock-absorbing rubber part during press-fitting, so that the shock-absorbing rubber part can be accurately press-fitted into the mounting groove of the steering gear housing.

[0022] 2. By setting a fixing clamp, when the press-fitting equipment is used to install the shock-absorbing rubber parts for the automobile steering system, the stability of the shock-absorbing rubber parts during press-fitting is improved, and the fixing operation of the steering gear housing with different structures is met;

[0023] When in use, when the user places the steering gear housing on the upper end of the limiting base, the two sides of the steering gear housing can be fixed by limiting the limiting clamps using two sets of fixing clamps. At the same time, several sets of limiting clamps can be adjusted arbitrarily according to the side structure of the steering gear housing, thereby improving its application range. The moving slider is driven to move by the lateral push rod. When several sets of limiting clamps on one side of the moving slider contact the side of the steering gear housing, the limiting clamps can be adjusted accordingly according to the side structure of the steering gear housing, so that the limiting clamps and the side of the steering gear housing are interlocked, and then the vertical push rod is used to drive the fixed pressure strip to move downward, so that The fixed pressure strip utilizes the tooth groove structure to clamp on the upper end of several groups of limit clamps, completes the fixing operation of several groups of limit clamps, and makes the steering gear housing be in a fixed state. When the lateral push rod drives the moving slider to reset, one end of the reset head will contact the side of the limit base, and the reset plate is driven to move by the reset head, so that the reset plate pushes several groups of limit clamps at the same time, so that several groups of limit clamps all extend outward, so that several groups of limit clamps maintain the same length, and completes the reset operation of several groups of limit clamps, avoiding the steering gear housing from tilting during the press-fitting operation of the shock-absorbing rubber parts, and improving its stability.

[0024] 3. By providing the first annular body, the second annular body and the third annular body, when the press-fitting equipment performs installation operation on the shock-absorbing rubber part for the automobile steering system, the structure of the shock-absorbing rubber part itself is optimized to avoid rebound during the press-fitting operation;

[0025] During operation, because the diameter of the first annular body is larger than that of the second annular body, and the diameter of the second annular body is larger than that of the third annular body, three groups of annular bodies are sequentially arranged on the surface of the rubber sleeve from large to small. After the rubber sleeve is pressed and installed, the annular bodies play a fixing role on it. Because the diameter of the third annular body is the smallest and the third annular body is the lowermost end of the rubber sleeve, during the press-fitting operation, the third annular body is first inserted into the notch of the steering gear housing, and the second annular body and the third annular body are sequentially pressed and installed into the notch of the steering gear housing. The small-diameter end is inserted first, so that the shock-absorbing rubber part will not rebound during press-fitting. BRIEF DESCRIPTION OF THE DRAWINGS

[0039] To solve the misalignment problem when the shock-absorbing rubber parts are pressed, Figure 3As shown, the limit member 10 includes a limit sleeve 12, a driver 13 and a telescopic arm 14, the telescopic arm 14 is fixedly mounted on the outer surface of one end of the limit sleeve 12, the driver 13 is arranged on the outer surfaces of both sides of the limit sleeve 12, and two groups of movable clamping blocks 18 are movably installed on the inner side of the limit sleeve 12. In order to solve the rebound problem of the shock-absorbing rubber part during the press-fitting operation, the limit sleeve 12 is arranged between the shock-absorbing rubber part and the steering gear housing, the lower end of the limit sleeve 12 is aligned with the mounting hole of the steering gear housing, the shock-absorbing rubber part to be installed is placed inside the limit sleeve 12, and the two sides of the shock-absorbing rubber part are limited and fixed by the movable clamping blocks 18. When the press assembler 8 moves downward, the shock-absorbing rubber part is guided and fixed by the movable clamping blocks 18 to avoid bending or rebound of the shock-absorbing rubber part during press-fitting.

[0040] A telescopic sleeve 16 is sleeved on one end of the telescopic arm 14, and a motor 15 is installed on the side of the telescopic sleeve 16. The telescopic arm 14 and the motor 15 are driven by gears, and the outer surface of the side of the telescopic arm 14 is a toothed structure. When in use, the limit member 10 adopts a telescopic structure design and can be extended outward when the shock-absorbing rubber member is installed. The motor 15 is used to drive the gear, so that the gear uses the toothed structure on the side of the telescopic arm 14 to drive the telescopic arm 14, so that the telescopic arm 14 moves telescopically inside the telescopic sleeve 16, so that the telescopic sleeve 16 drives the limit sleeve 12 to move, and the use length of the limit sleeve 12 is adjusted. When the limit sleeve 12 is hidden and stored, any specification of shock-absorbing rubber members can be installed between the press 8 and the limit base 7.

The V-shaped structure is arranged so that when the movable clamping block 18 contacts with the shock-absorbing rubber part, a two-point docking structure is formed. With the arrangement of the two groups of movable clamping blocks 18, the four-point limiting fixation of the shock-absorbing rubber part is completed, thereby improving the fixing effect of the limiting member 10 on the shock-absorbing rubber part.

[0042] like Figure 5 As shown, the upper end of the movable clamping block 18 is spliced ​​and installed with a beveled top head 19, and the movable clamping block 18 and the beveled top head 19 are spliced ​​and fixed by a docking clamping strip 21. The side of the beveled top head 19 is an inclined V-shaped structure, and a plurality of groups of transverse rollers 20 are vertically distributed on the outer surface of one side of the movable clamping block 18. When the press 8 moves downward, when the pressing head at the bottom of the press 8 enters the interior of the limiting sleeve 12, the pressing head structure of the press 8 can be introduced between the two groups of movable clamping blocks 18 by utilizing the beveled top head 19 with an inclined V-shaped structure, so as to avoid the pressing head of the press 8 being stuck on the outside of the movable clamping block 18, and the provision of a plurality of groups of transverse rollers 20 can reduce the friction between the rubber sleeve 1 and the two groups of movable clamping blocks 18.

[0043] To solve the problem of fixing steering gear housings of different sizes, such as Figure 6 As shown, the fixed clamp 11 includes several groups of limit clamps 22 and a movable slider 28. The several groups of limit clamps 22 are movably installed on the inner side of the movable slider 28, and the interior of the movable slider 28 is a hollow structure. When the user places the steering gear housing on the upper end of the limit base 7, the two groups of fixed clamps 11 can be used to limit and fix the two sides of the steering gear housing through the limit clamps 22. At the same time, the several groups of limit clamps 22 can be adjusted arbitrarily according to the side structure of the steering gear housing to improve its scope of application.

[0044] A reset plate 24 for use with the limit clamp 22 is movably installed inside the movable slider 28. Two groups of reset pins 25 are provided at one end of the reset plate 24. Both groups of reset pins 25 are movably sleeved on the inner side of the movable slider 28. When the lateral push rod 26 drives the movable slider 28 to reset, one end of the reset pin 25 will contact the side of the limit base 7. The reset plate 24 is driven to move by the reset pin 25, so that the reset plate 24 pushes several groups of limit clamps 22 at the same time, so that several groups of limit clamps 22 are extended outward, so that several groups of limit clamps 22 maintain the same length, and the reset operation of several groups of limit clamps 22 is completed.

[0047] When in use, the latest developed shock-absorbing rubber structure is a counter-pressed structure, which does not have the drawback of unstable stiffness performance of the single inner sleeve L-shaped structure. However, the counter-pressed structure is prone to rebound during the press-fitting process, which is a very common problem in the industry. At the same time, the traditional press-fitting equipment does not have an auxiliary guide structure, which makes the shock-absorbing rubber parts prone to tilt, dislocation, and rebound during the press-fitting process, reducing its press-fitting effect;

[0048] To this end, by providing the stopper 10, when the press-fitting device is performing installation operation on the shock-absorbing rubber part for the automobile steering system, an installation guide structure can be formed between the steering gear housing and the shock-absorbing rubber part, thereby avoiding the dislocation and rebound of the shock-absorbing rubber part during press-fitting, thereby improving the press-fitting effect;

[0049] During operation, the setting of the limiting member 10 can be used to limit and connect the rubber sleeve 1 and the metal sleeve 2 when the shock-absorbing rubber part is pressed and installed. The rubber sleeve 1 is sleeved on the inner side of the limiting member 10, and the shock-absorbing rubber part is squeezed from top to bottom by the press-fitting device 8, so that the rubber sleeve 1 and the metal sleeve 2 are pressed and installed in the steering gear housing installed by the limiting base 7. The two sets of fixing clamps 11 can be adjusted arbitrarily according to the side structure of the steering gear housing, so as to meet the fixing operation of steering gear housings of different sizes. During installation, the lower end of the limiting sleeve 12 is aligned with the mounting hole of the steering gear housing, and the shock-absorbing rubber part to be installed is placed inside the limiting sleeve 12. The two sides of the shock-absorbing rubber part are limited and fixed by the moving clamp block 18. The moving clamp block 18 uses the V-shaped structure to make the moving When the clamping block 18 contacts the shock-absorbing rubber part, a two-point docking structure is formed. With the arrangement of the two groups of mobile clamping blocks 18, the four-point limit fixation of the shock-absorbing rubber part is completed, and the fixing effect of the limiter 10 on the shock-absorbing rubber part is improved. Secondly, the inclined V-shaped inclined top head 19 can be used to guide the pressure head structure of the press 8 between the two groups of mobile clamping blocks 18 to avoid the pressure head of the press 8 being stuck on the outside of the mobile clamping block 18. The arrangement of several groups of transverse rollers 20 can reduce the friction between the rubber sleeve 1 and the two groups of mobile clamping blocks 18. When the press 8 moves down, the shock-absorbing rubber part is guided and fixed by the mobile clamping block 18 to avoid bending or rebound of the shock-absorbing rubber part during press-fitting, so that the shock-absorbing rubber part can be accurately press-fitted into the mounting groove of the steering gear housing.

[0050] By providing the fixing clamp 11, when the press-fitting equipment is performing installation operation on the shock-absorbing rubber part for the automobile steering system, the stability of the shock-absorbing rubber part during press-fitting is improved, and the fixing operation of the steering housing with different structures is satisfied;

[0051] During use, when the user places the steering gear housing on the upper end of the limiting base 7, the two groups of fixing clamps 11 can be used to limit and fix the two sides of the steering gear housing through the limiting clamps 22. At the same time, several groups of limiting clamps 22 can be adjusted arbitrarily according to the side structure of the steering gear housing to improve its application range. The moving slider 28 is driven to move by the lateral push rod 26. When several groups of limiting clamps 22 on one side of the moving slider 28 contact the side of the steering gear housing, the limiting clamps 22 can be adjusted accordingly according to the side structure of the steering gear housing, so that the limiting clamps 22 and the side of the steering gear housing are interlocked, and then the vertical push rod 29 is used to drive the fixed pressure strip 23 to move downward, so that the fixed The pressure strip 23 is clamped on the upper ends of several groups of limit clamps 22 by means of the tooth groove structure, and the fixing operation of several groups of limit clamps 22 is completed, so that the steering gear housing is in a fixed state. When the lateral push rod 26 drives the movable slider 28 to reset, one end of the reset head 25 will contact the side of the limit base 7, and the reset plate 24 is driven to move by the reset head 25, so that the reset plate 24 pushes several groups of limit clamps 22 at the same time, so that several groups of limit clamps 22 are all extended outward, so that several groups of limit clamps 22 maintain the same length, and the reset operation of several groups of limit clamps 22 is completed, so as to avoid the steering gear housing from tilting when the shock-absorbing rubber parts are pressed and installed, and improve its stability;

[0052] By providing the first annular body 3, the second annular body 4 and the third annular body 5, when the press-fitting device performs installation operation on the shock-absorbing rubber part for the automobile steering system, the structure of the shock-absorbing rubber part itself is optimized to avoid rebounding during the press-fitting operation;

[0053] During operation, because the diameter of the first annular body 3 is larger than the diameter of the second annular body 4, and the diameter of the second annular body 4 is larger than the diameter of the third annular body 5, three groups of annular bodies are sequentially arranged on the surface of the rubber sleeve 1 from large to small. After the rubber sleeve 1 is pressed and installed, the annular bodies play a fixing role on it. Because the caliber of the third annular body 5 is the smallest, and because the third annular body 5 is the lowermost end of the rubber sleeve 1, during the press-fitting operation, the third annular body 5 is first inserted into the notch of the steering gear housing, and the second annular body 4 and the third annular body 5 are sequentially pressed and installed into the notch of the steering gear housing. The small-caliber end is inserted first, so that the shock-absorbing rubber part will not rebound during press-fitting.
