Description

Technical Field

[0001] The utility model belongs to the technical field of automobile power assembly press-fitting equipment, and in particular relates to a floating centering device. Background Art

[0002] When press-fitting the parts of the automotive powertrain, a press machine is usually used to press-fit the parts, so as to assemble different parts together. However, the current press machine cannot return to the original center, which causes the parts to be easily worn or deformed during the press-fitting process, which not only affects the assembly efficiency and quality of the assembly, but also causes material waste and poor economy. Therefore, in view of the problem that the current press machine cannot return to the original center, resulting in low product press-fitting efficiency and poor press-fitting quality, it is necessary to provide a more reasonable technical solution to solve the technical problems existing in the prior art. Utility Model Content

[0003] The utility model aims to provide a floating centering device to solve the problem in the prior art that the press-fitting machine cannot return to the original center, resulting in low product press-fitting efficiency and poor press-fitting quality.

[0004] In order to achieve the above-mentioned purpose, the utility model provides a floating centering device, the upper and lower ends of which are respectively connected to a pressure head and a connecting piece; the floating centering device comprises:

[0005] An upper mounting plate, used for connecting the pressure head, a limiting member for limiting the position of the parts is provided at the lower end of the pressure head, and a through hole for avoiding the limiting member is provided on the upper mounting plate;

[0006] A lower mounting plate, used for placing parts to be press-fitted, the lower mounting plate is formed into a structure adapted to the upper mounting plate, and the lower mounting plate is connected to a connecting piece; and

[0007] A buffer with elasticity, which can be compressed when under pressure and restored when the pressure is released, the buffer is arranged in at least three groups and evenly spaced along the circumferential direction of the lower mounting plate, wherein the middle area of ​​the buffer forms a placement area for the press-fitted parts; the upper and lower ends of the buffer are respectively connected to the upper mounting plate and the lower mounting plate;

[0008] When the pressing head is connected to the upper mounting plate, the limiting member is inserted into the through hole and abuts against the part to be pressed, so as to maintain the position of the part to be pressed relative to the lower mounting plate.

[0009] Optionally, the buffer members are provided in four numbers and are symmetrically arranged.

[0010] Optionally, the buffer member is configured as a rubber member.

[0011] Optionally, threaded holes are respectively provided on the upper mounting plate and the lower mounting plate, locking screws are respectively provided at both ends of the buffer, and the locking screws are inserted into the threaded holes.

[0012] Optionally, the limiting member is equipped with a positioning screw.

[0013] The working process of the floating centering device can be summarized as follows: the parts to be pressed are placed on the lower mounting plate, and then the upper end of the buffer is connected to the upper pressing plate. After that, the pressure head approaches the upper pressing plate, and the limiting member is inserted into the through hole, and then the limiting member is abutted against the part to be pressed, thereby achieving the limitation of the part. After that, the pressure head continuously applies pressure toward the part to achieve the pressing of the part. Since the buffer is arranged around the part, during the pressing process, the buffer will deform and compress after being pressed, which can slow down the speed of pressing and convert the rigid force into flexible force, so that the parts can be pressed evenly and smoothly. This arrangement can produce floating during the pressing and material removal process, has a better flexible effect, can return to the original centering, and effectively avoid damage to the product during the hard connection pressing process.

[0014] Through the above technical solution, the floating centering device compresses and restores the buffer so that the upper mounting plate has a floating swing relative to the lower mounting plate, which can play a great advantage under conditions where the quality consistency of the pressed products is poor, avoiding damage to the products and equipment. At the same time, after the press-fitting is completed, the floating centering device can return to the original centering. Thereby, the problem of poor consistency of the current press-fitting machine when pressing parts is effectively solved. In addition, the floating centering device is low-cost, and the cost is greatly reduced compared to the Korean CM centering device. Compared with the commonly used structures in the industry, it saves three or even four times, thereby greatly reducing the equipment cost and manual debugging cost.

[0019] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the description of these embodiments is intended to help understand the present invention, but does not constitute a limitation on the present invention. The specific structural and functional details disclosed herein are only used to describe the embodiments of the present invention. However, the present invention can be embodied in many alternative forms, and it should not be understood that the present invention is limited to the embodiments described herein.

[0020] In the specific implementation of the utility model, a floating centering device is provided, the upper and lower ends of which are respectively connected to the pressure head and the connecting piece. When the pressure head applies force to the floating centering device, the force can be evenly applied to the parts to be press-fitted through the floating centering device, thereby completing the press-fitting work smoothly and gently, which can reduce damage to parts and equipment. Figure 1 and Figure 2 One embodiment thereof is shown.

[0021] See also Figure 1 and Figure 2 As shown, the floating centering device includes: an upper mounting plate 3, which is used to connect the pressure head 1, and the lower end of the pressure head 1 is provided with a limiter for limiting the part 7, and the upper mounting plate 3 is provided with a through hole for avoiding the limiter; a lower mounting plate 4, which is used to place the part 7 to be pressed, and the lower mounting plate 4 is formed into a structure adapted to the upper mounting plate 3, and the lower mounting plate 4 is connected to the connecting member 2; and an elastic buffer 5, which can be compressed when pressed and restored when the pressure is released, and the buffer 5 is configured as at least three groups and evenly spaced along the circumferential direction of the lower mounting plate 4, wherein the middle area of ​​the buffer 5 is formed as a placement area for the pressed part 7; the upper and lower ends of the buffer 5 are respectively connected to the upper mounting plate 3 and the lower mounting plate 4. When the pressure head 1 is connected to the upper mounting plate 3, the limiter is inserted into the through hole and abuts against the part 7 to be pressed, so as to maintain the position of the part 7 to be pressed relative to the lower mounting plate 4.

[0022] The working process of the floating centering device can be summarized as follows: the part 7 to be pressed is placed on the lower mounting plate 4, and then the upper end of the buffer 5 is connected to the upper press plate. Thereafter, the pressure head 1 approaches the upper press plate, and the limiting member is inserted into the through hole, and then the limiting member abuts against the part 7 to be pressed, thereby achieving the limitation of the part 7. Thereafter, the pressure head 1 continuously applies pressure toward the part 7 to achieve the part press-fitting work. Since the buffer 5 is arranged around the part, during the press-fitting process, the buffer 5 will deform and compress after being pressed, which can slow down the speed of pressing and convert the rigid force into a flexible force, thereby allowing the part to be pressed evenly and smoothly. This arrangement can produce floating during the press-fitting and material removal process, has a better flexible effect, can return to the original center, and effectively avoid damage to the product during the hard connection press-fitting process.

[0023] Through the above technical solution, the floating centering device compresses and restores the buffer 5, so that the upper mounting plate 3 has a floating swing relative to the lower mounting plate 4, which can play a great advantage under the working conditions where the quality consistency of the pressed product is poor, avoiding damage to the product and equipment. At the same time, after the press-fitting is completed, the floating centering device can return to the original centering, so as to prepare for the next press-fitting work. In this way, the problem of poor consistency of the current press-fitting machine when press-fitting parts can be effectively solved. In addition, the floating centering device is low-cost, and the cost has been greatly reduced compared to the Korean CM centering device. Compared with the currently commonly used structures in the industry, it saves three or even four times, thereby greatly reducing the equipment cost and manual debugging cost.

[0024] Compared with the existing press machines, the floating centering device has the following beneficial effects: 1. The buffer part 5 is used to make the force more uniform. After pressing, the returning to the original centering effect of the floating centering device is better than the centering effect of the press machines using plane bearings in the current market; 2. The floating centering device has a certain tolerance for its installation accuracy. During the debugging process of the floating centering device, the accuracy requirements are not high, which can reduce the cost of high-precision processing; 3. The cost is lower, which has the effect of reducing costs and increasing efficiency during use, which is beneficial for enterprises to promote and use it.

[0025] It should be noted that the pressure head 1 and the connecting piece 2 are both existing technologies.

[0026] In an embodiment provided in the present disclosure, four buffer members 5 are provided and arranged symmetrically. With this layout, the buffer members 5 can be used to absorb and disperse the pressing force, so that the parts are evenly stressed. This design helps to avoid deformation or damage of the parts 7 due to uneven force during the pressing process, thereby ensuring the pressing quality of the parts and reducing wear on the parts and equipment.

[0027] The four buffers 5 are symmetrically arranged to ensure that the press-fitting force is evenly distributed in all directions, thereby further reducing the wear of the parts 7 and the equipment. This layout helps to improve the stability of the press-fitting process, reduce the error caused by uneven force, and make the press-fitting result more accurate and reliable.

[0028] Of course, in other embodiments, the buffer members 5 may also be provided in any suitable number such as three, five, six, etc., and those skilled in the art may make an adaptive selection according to the specifications and shapes of the parts 7 to be press-fitted.

[0029] In the present disclosure, the buffer 5 is configured as a rubber part. The rubber part has good wear resistance, oil resistance and aging resistance, can maintain stable performance in harsh working environments, and extend the service life of the buffer part. In addition, the rubber part has low cost, simple manufacturing process, and good economy and practicality.

[0030] As an elastic material, rubber has excellent compression performance and recovery ability. During the press-fitting process, the presence of vibration and impact often causes certain damage to the equipment. The rubber buffer 5 can evenly bear the gravity from above, ensure uniform pressure distribution, and avoid damage to the part 7 due to uneven force. At the same time, when under pressure, the rubber part can compress smoothly, effectively absorb and disperse the impact force, and protect the part 7 from impact damage. When the pressure is released, the rubber buffer can slowly return to its original shape and performance, thereby ensuring the smooth progress of the next press-fitting process.

[0031] In other embodiments, the buffer member 5 can also be configured as a damper, a spring or any other suitable buffer-type part that can be compressed when under pressure and reset after the pressure is released. In this regard, technical personnel in this field can flexibly select it according to the application object and application scenario.

[0032] In an embodiment provided by the present disclosure, threaded holes are respectively provided on the upper mounting plate 3 and the lower mounting plate 4, and locking screws 6 are respectively provided at both ends of the buffer 5, and the locking screws 6 are inserted into the threaded holes. The buffer 5 is used to reduce vibration and impact, and it absorbs and disperses the pressure caused by external factors during the press-fitting process of the device. The locking screws 6 are designed at both ends of the buffer 5, which can not only tightly connect the buffer 5 with the upper mounting plate 3 and the lower mounting plate 4, but also control the buffering effect by adjusting the tightness of the screws.

[0033] In addition, through the combination of the threaded hole and the locking screw 6, it can be quickly installed and disassembled, which not only simplifies the installation process but also improves work efficiency. Secondly, due to the use of a threaded structure, the connection is more firm and reliable, and is not easy to loosen or fall off. In addition, by adjusting the tightness of the locking screw 6, the buffering effect can be flexibly controlled to meet different press-fitting requirements.

[0034] In the present disclosure, the limiter is equipped with a positioning screw. As a common fastener, the positioning screw has the advantages of simple structure, easy use, and low cost. By adjusting the tightening degree of the positioning screw, the part 7 to be pressed can be stably fixed, which not only simplifies the installation process and reduces the difficulty of operation, but also shows good stability and reliability in the actual working process. The limiter has a significant effect on the stable limiting of the parts during the working process, effectively avoiding quality problems caused by position deviation, and improving production efficiency and product quality.

[0035] It should be noted that in the present disclosure, both the positioning screw and the locking screw 6 are fastening parts in the prior art and can be purchased on the market.

[0036] Finally, it should be noted that the utility model is not limited to the above optional implementations, and anyone can derive other various forms of products under the inspiration of the utility model. The above specific implementations should not be understood as limiting the scope of protection of the utility model. The scope of protection of the utility model shall be based on the definition in the claims, and the description can be used to interpret the claims.
