[0035] Therefore, the utility model provides a kind of gear press fitting tool 100, to solve the problems of press fitting deviation, unstable quality and low efficiency caused by not using gear center hole positioning in prior art.

[0036] Please refer to Figure 1 In an embodiment of the utility model, the gear press fitting tool 100 includes:

[0037] Lower die tooling 1 is provided with the first positioning part 121 for positioning the gear box 300;

[0038] Upper die tooling 2 is spaced apart and oppositely arranged with the lower die tooling 1, and the second positioning part 221 for positioning the gear 200 is arranged on the side of the upper die tooling 2 facing the lower die tooling 1, the second positioning part 221 is arranged towards the first positioning part 121, and the upper die tooling 2 is driven by a press to move towards the direction close to or away from the lower die tooling 1, so as to press the gear 200 into the gear box 300 or reset the upper die tooling 2;

[0039] Guiding assembly 3 is arranged between the lower die tooling 1 and the upper die tooling 2, and connects the lower die tooling 1 and the upper die tooling 2.

[0040] In this embodiment, the lower die tooling 1 serves as the base of the press-fitting tooling, which is provided with a first positioning part 121 for positioning the gear box 300. The first positioning part 121 can be a groove or a hole matched with the gear box 300, ensuring that the gear box 300 can be stably placed in the press-fitting position. It can also include fixing devices such as clamps, pins, etc., to further enhance the positioning accuracy. By positioning the gear box 300 through the first positioning part 121, assembly errors caused by inaccurate positioning can be avoided, improving the qualification rate of the product.

[0041] The upper die tooling 2 is spaced apart from and opposite to the lower die tooling 1, and the side facing the lower die tooling 1 is provided with a second positioning part 221 for positioning the gear 200.

The second positioning part 221 is arranged towards the first positioning part 121, i.e., the positions of the gear 200 and the gear box 300 are accurately aligned, which can reduce the problem of offset misalignment that may occur during the press-fitting process, ensuring that the center distance of the gear 200 meets the design requirements. The upper die tooling 2 is connected with the driving mechanism of the press machine, and the press machine drives the upper die tooling 2 to move in the vertical direction through hydraulic, pneumatic or mechanical means, realizing the press-in of the gear 200 or the resetting of the upper die tooling 2. The driving mode of the press machine can ensure the stability and controllability of the movement of the upper die tooling 2, accurately control the press-fitting force and press-fitting stroke, avoid damage to the gear 200 or press-fitting failure due to excessive or insufficient press-fitting force, and improve the production efficiency and product quality.

[0042] The guide assembly 3 is arranged between the lower die tooling 1 and the upper die tooling 2 and connects the two. The guide assembly 3 can be in the form of a guide column, guide rail, etc., ensuring that the upper and lower die tooling 1 moves smoothly along the preset path during work. By providing stable guiding function, unintended movement between the upper and lower die tooling 1 is prevented, enhancing the stability and reliability of the entire system, while also helping to improve the press-fitting accuracy.

[0043] The technical scheme of the utility model discloses a first positioning part 121 for positioning the gear box 300 is arranged on the lower die tool 1, and a second positioning part 221 for positioning the gear 200 is arranged on the upper die tool 2, and the second positioning part 221 is arranged towards the first positioning part 121, so that the gear 200 and the gear box 300 can be accurately aligned during the pressing process, and the situation that the center distance of the gear 200 does not meet the requirement due to deviation is avoided.

[0044] Please refer to Figure 1 and Figure 2 In an embodiment of the utility model, the lower die tool 1 comprises:

[0045] The lower die mounting plate 11;

[0046] The lower die body 12 is arranged on the side of the lower die mounting plate 11 towards the upper die tool 2, and the first positioning part 121 is a positioning column arranged on the lower die body 12.

[0047] In the embodiment, the lower die mounting plate 11 is the basic component of the whole lower die tool 1, which is a solid flat plate structure for fixing and supporting the lower die body 12. The lower die mounting plate 11 can provide a stable basic platform, so that the lower die body 12 can remain absolutely stationary during the pressing operation of the gear 200, preventing position deviation caused by external force.

[0048] The lower die body 12 directly participates in the positioning of the gear box 300, which can be fixed on the side of the lower die mounting plate 11 facing the upper die tool 2 through the first fixing part 13 (such as lower die fixing screw). The first positioning part 121 is a positioning column arranged on the lower die body 12. The positioning column is a protruding part matched with the hole or groove on the gear box 300, ensuring that the gear box 300 can be accurately aligned and fixed at the pressing position. The number, size and distribution of the positioning column depend on the specific gear box 300. By accurately positioning the gear box 300, assembly errors caused by inaccurate positioning can be avoided, ensuring that the gear 200 can be accurately and correctly pressed into the gear box 300, improving the quality consistency of the product.

[0049] Please refer to Figure 1 andFigure 2 In an embodiment of the present application, the upper die tooling 2 comprises:

[0050] The upper die mounting plate 21;

[0051] The upper die body 22 is arranged on the side of the upper die mounting plate 21 facing the lower die tooling 1, and the second positioning part 221 is a positioning groove arranged on the upper die body 22.

[0052] In this embodiment, the upper die mounting plate 21 is the base component of the entire upper die tooling 2, which is a solid flat plate structure used to fix and support the upper die body 22 and can be connected with the press machine, so that the upper die tooling 2 can move up and down under the action of pressure. The upper die mounting plate 21 can provide a stable base platform to ensure that the upper die body 22 can move accurately along the preset path when pressure is applied, thereby ensuring that the gear 200 can be accurately pressed into the gear box 300.

[0053] The upper die body 22 directly participates in the positioning and pressing process of the gear 200, and it can be fixed on the side of the upper die mounting plate 21 facing the lower die tooling 1 through the second fixing part 23 (such as upper die fixing screws). The second positioning part 221 is a positioning groove arranged on the upper die body 22. The positioning groove is a groove designed for positioning the gear 200, and its size and shape match the center hole of the gear 200. The function of the positioning groove is to firmly fix the gear 200 in the pressing position before pressing, so that the gear 200 will not shift during the pressing process. By using the positioning groove to accurately position the gear 200, the accuracy of the gear 200 pressing can be improved, and the center distance between the gears 200 can be ensured to meet the design requirements. This not only can improve the quality stability of the product, but also can reduce the rate of defective products caused by assembly errors, thereby improving the production efficiency.

[0054] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, the side of the upper die mounting plate 21 away from the lower die tooling 1 is provided with a pressure head 5, the pressure head 5 is arranged opposite to the second positioning part 221, and the pressure head 5 is used to connect the press machine.

[0055] In the embodiment, the pressure head 5 is a solid and shaped component, one end of which can be fixed to the side of the upper die mounting plate 21 away from the lower die tooling 1 through a third fixing member 24 (such as a pressure head fixing screw), and the other end of which can be connected with the press through screw threads, an embedded interface or other connection means. By arranging the pressure head 5 on the upper die mounting plate 21, the pressure output by the press can be directly and uniformly applied to the upper die body 22, thereby accurately controlling the process of pressing the gear 200 into the gear box 300. The pressure head 5 is also arranged opposite to the second positioning part 221, which means that the position of the pressure head 5 is aligned with the second positioning part 221 in the upper die body 22, so as to ensure that the pressure applied through the pressure head 5 can directly act on the gear 200 placed in the second positioning part 221, so that the gear 200 can be accurately pressed into the gear box 300. This layout can ensure that the transmission path of the pressure is optimized, reduce energy loss, and avoid the risk of gear 200 deviation or damage due to uneven force distribution.

[0056] Referring to Figure 1 and Figure 2 In an embodiment of the utility model, the lower die body 12 and / or the upper die body 22 are provided with a positioning member 4, which is used for positioning the positions of the lower die body 12 and the upper die body 22.

[0057] In the embodiment, the positioning member 4 can be in various forms, such as a pin, a guide block or other types of mechanical elements, which are installed on the lower die body 12 and / or the upper die body 22, that is, the positioning member 4 can be arranged on only one or both of the lower die body 12 and the upper die body 22. The lower die body 12 and the upper die body 22 of the embodiment are each provided with one positioning member 4, which can ensure that the upper and lower die bodies 12 can be accurately aligned each time of operation. By accurately aligning the positions of the upper and lower die bodies 12, the product quality problems caused by position deviation can be effectively reduced, such as deviation and misplacement of the gear 200 during pressing.

[0058] Referring to Figure 1 and Figure 2 In an embodiment of the utility model, the guide assembly 3 comprises:

[0059] a plurality of guide columns 31, which are arranged at intervals on the lower die tooling 1;

[0060] a plurality of limiting members 32, which are arranged one-to-one at the ends of the plurality of guide columns 31 away from the lower die tooling 1, the upper die tooling 2 is sleeved on the guide columns 31 and located between the limiting members 32 and the lower die tooling 1;

[0061] a plurality of elastic members 33, which are sleeved one-to-one on the plurality of guide columns 31.

[0062] In this embodiment, the guide columns 31 can be solid and straight metal rods or tubes that are evenly distributed and fixed on the lower mold tooling 1 to provide linear guiding function. The number and position of these guide columns 31 are designed according to actual needs to ensure that the upper mold tooling 2 can move smoothly. By providing a stable guiding path, it can be ensured that the upper mold tooling 2 can move accurately along the predetermined trajectory during the pressing operation, avoiding position deviation caused by irregular movement.

[0063] The limiting member 32 can be a nut, a check ring or other types of mechanical elements, which is installed at the end of the guide column 31 away from the lower mold mounting plate 11, i.e. the limiting member 32 is installed at the top end of the guide column 31. The limiting member 32 is used to limit the maximum stroke of the upper mold tooling 2 to prevent it from moving too much. The upper mold tooling 2 is provided with a corresponding hole or guide sleeve so that it can slide freely along the guide column 31. This design allows the upper mold tooling 2 to move up and down under the action of the press machine while maintaining accurate alignment with the lower mold tooling 1.

[0064] The elastic member 33 can be made of a spring or other elastic material, which is sleeved on the guide column 31 and located between the upper mold tooling 2 and the lower mold tooling 1. When the upper mold tooling 2 moves downward under the pressure applied by the press machine, the elastic member 33 will be compressed first. This process helps to absorb part of the impact force, reducing the direct impact on the upper and lower mold tooling 1 and the gear 200, thereby avoiding damage to the parts or surface defects caused by instantaneous high pressure. Once the pressing operation is completed, the elastic member 33 will try to restore its original shape due to its elastic properties after the press machine releases the pressure. This rebound force helps to push the upper mold tooling 2 to move upward, making it quickly and automatically return to the initial position, ready for the next pressing operation, at which time the operator can take out the gear box 300 with the pressed gear 200.

[0065] Please refer to Figure 1 and Figure 2 In an embodiment of the present application, a plurality of guide columns 31 are equally spaced on the lower mold tooling 1.

[0066] In the embodiment, the plurality of guide columns 31 are equidistantly arranged on the lower mold mounting plate 11, which means that the distribution of the guide columns 31 on the lower mold mounting plate 11 follows a certain rule, and the distance between them is equal. For example, if four guide columns 31 are used, they can be distributed on the four corners of a square or rectangle on the lower mold mounting plate 11, ensuring that the distance from each guide column 31 to the center is the same, or evenly distributed according to other geometric layouts. The equidistant arrangement can ensure that the force received by the upper mold tooling 2 during the lowering and raising process is more evenly distributed in all directions, reducing the phenomenon of deflection or jamming caused by uneven force, thereby improving the pressing precision. And through the uniform distribution of guide columns 31, the stability of the entire pressing tooling can be increased, so that the relative movement between the upper and lower mold toolings 1 is more stable, reducing vibration and shaking, which is beneficial to precise operation.

[0067] Referring to Figure 1 and Figure 2 In an embodiment of the utility model, the guide assembly 3 further comprises a plurality of bearing members 34; the upper mold tooling 2 is provided with a plurality of guide holes 211, and the plurality of bearing members 34 are one-to-one sleeved on the plurality of guide columns 31 and arranged in the plurality of guide holes 211.

[0068] In the embodiment, the bearing member 34 generally refers to a component such as a rolling bearing or a linear motion bearing, which is installed on the guide column 31 and used to reduce the frictional resistance between the guide column 31 and the upper mold tooling 2, so that the upper mold tooling 2 can move up and down along the guide column 31 more smoothly. By using the bearing member 34, the friction can be significantly reduced, thereby reducing wear and prolonging the service life of the equipment. The upper mold mounting plate 21 is provided with a plurality of guide holes 211, and the size of the guide hole 211 matches the guide column 31. Each guide column 31 is sleeved with a corresponding bearing member 34, so that when the upper mold mounting plate 21 moves along the guide column 31, it is actually achieved by the bearing member 34 to move smoothly. The existence of the bearing member 34 can reduce the error caused by direct metal contact, so that the upper mold mounting plate 21 can move under more precise control, improving the positioning accuracy of the entire pressing tooling.

[0069] Referring to Figure 1 and Figure 2 In an embodiment of the utility model, each bearing member 34 is interference fitted in the corresponding guide hole 211.

[0070] In the present embodiment, interference fit is a method of assembly that achieves a tight fit by pressing a part into a hole with a size slightly larger than its mating hole diameter. Specifically, this means that the outer diameter of the bearing piece 34 is slightly larger than the diameter of the guide hole 211, and when installed, a certain pressure needs to be applied to make the bearing piece 34 enter the guide hole 211, thereby forming a tight and gapless connection. Interference fit can effectively prevent the bearing piece 34 from loosening or shifting during operation, ensuring that the bearing piece 34 can maintain stable position and performance throughout the entire press fitting cycle. Because there is no gap, interference fit can reduce errors caused by the slight movement between moving parts, helping to maintain high positioning accuracy, which is particularly important for gear 200 press fitting that requires high precision positioning.

[0071] The utility model discloses still propose a kind of press fitting equipment, the press fitting equipment includes press machine and gear press fitting tool 100, the specific structure of the gear press fitting tool 100 refers to above-mentioned embodiment, since the present press fitting equipment has adopted all technical solutions of above-mentioned all embodiments, at least have all beneficial effects brought by the technical solutions of above-mentioned embodiment, here no longer repeat.

In addition, in order to facilitate the smooth up-and-down movement of the upper die tool 2 during operation and reduce friction, the bearing piece 34 is firmly assembled on the upper die mounting plate 21 in an interference fit manner.

[0074] In the lower die tool 1, the fourth fixing piece 35 is used to fixedly connect the plurality of guide columns 31 to the lower die mounting plate 11. Subsequently, the plurality of elastic pieces 33 are sleeved one by one into the plurality of guide columns 31, and the first fixing piece 13 is used to fixedly connect the lower die body 12 to the lower die mounting plate 11.

[0075] After the assembly of the upper die tool 2 is completed, it is sleeved into the lower die tool 1, and then the two are fixedly connected by using a plurality of fourth fixing members 35 and a corresponding number of limiting members 32. After the connection is completed, the upper die tool 2 is pressed to an appropriate height, the positions of the upper die body 22 and the lower die body 12 are accurately positioned by using the positioning member 4, and finally the second fixing member 23 is tightened to ensure the stability and accuracy of the overall structure. In this way, the assembly of the entire gear press-fitting tool 100 can be realized, and the accurate positioning and smooth operation of the upper die and the lower die during the operation process can be ensured.

Then, the start button of the press-fitting device is pressed, and the upper die mounting plate 21 starts to move downward under the driving of the press machine until the gear 200 is accurately and correctly pressed into the gear box 300. When the preset press machine setting height is reached, the press machine will automatically return to the original position, and at this time, the elastic member 33 will push the upper die mounting plate 21 back to the initial position. The operator takes out the gear box 300 in which the gear 200 has been press-fitted, and the operation is completed. During the entire press-fitting process, the press machine can monitor the pressing height and the press-in force in real time, thereby effectively ensuring the consistency of the product quality and improving the production yield.
