Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of bushing installation, in particular to a floating pressure head device for installing a bushing. Background Art
[0002] In the field of automated production, the installation of bushings is a key link that has a significant impact on the accuracy, cost and production efficiency of the equipment.
[0003] Currently, there are many challenges in the automatic installation of bushings. Due to the extremely high requirements for bushing installation position and accuracy, existing installation equipment usually uses a high-precision positioning pressure head to ensure installation accuracy.
[0004] For example, Chinese patent document CN104339144A discloses an assembly system and an assembly method for press-fitting bushings. The assembly system includes a mounting platform fixed with an engine body and an assembly device fixed to the mounting platform. The assembly device includes an automatic press-fitting device, which includes a first servo press-fitting device equipped with a first ram guide and a second servo press-fitting device equipped with a second ram guide. The first ram guide and the second ram guide are arranged on opposite sides of the engine body. In the assembly method, bushings are first installed on the second ram guide and the first ram guide, and then the bushings on the second ram guide and the first ram guide are press-fitted into the engine body.
[0005] However, this high-precision positioning indenter has a number of drawbacks. First, maintenance costs are high. Over long-term use, even minor wear and tear or precision deviations can lead to performance degradation of the entire device, necessitating frequent maintenance and calibration, which consumes significant manpower, material, and financial resources. Second, high-precision positioning indenters have a short service life. Frequent replacement not only increases production costs but also compromises the continuity and stability of production.
[0006] Furthermore, traditional installation equipment requires stringent overall precision, significantly increasing manufacturing costs. Furthermore, when product changes or bushings of varying specifications are required during production, traditional equipment adjustments become extremely complex. This often requires comprehensive recalibration and commissioning, and may even require the replacement of key components. This not only complicates adjustments but can also lead to production halts, reduced efficiency, and increased costs.
[0007] Traditional installation equipment lacks sufficient flexibility and adaptability when faced with diverse workpiece shapes and installation requirements. When encountering workpieces with complex structures and unusual mounting hole locations, traditional equipment struggles to ensure accurate bushing installation, leading to installation deviations and negatively impacting product quality.

[0043] The existing automated equipment for installing bushings mainly adopts high-precision positioning pressure heads, which have high maintenance costs and short service life. The use of the floating pressure head device of the utility model can relax the requirements on equipment accuracy, while ensuring accuracy, reducing manufacturing and maintenance costs, and greatly reducing the difficulty of equipment adjustment.

For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0046] Example 1:
[0047] like Figures 1 to 7 As shown, a floating head device for installing a bushing:
[0048] It includes a guide sleeve 1, a bushing pressure rod 11, a bushing pressure head 2 and a floating adjustment mechanism 3;
[0049] The guide sleeve 1 is fixed on the supporting structure, and the bushing pressure rod 11 is movably arranged in the guide sleeve 1. There is a radial floating gap between the bushing pressure rod 11 and the guide sleeve 1. The rear end of the bushing pressure rod 11 is connected to the driving device, and the front end of the bushing pressure rod 11 extends to the front side of the guide sleeve 1 and is connected to the rear end of the bushing pressure head 2.
[0050] The floating adjustment mechanism 3 includes a base 31, a guide rod 32, a contact head 33 and an elastic connecting member 34. The floating adjustment mechanism 3 is sleeved on the outer side of the bushing pressure head 2 through the base 31. The base 31 is provided with base holes 311 distributed on the circumferential periphery of the bushing pressure head 2. The guide rod 32 is movably inserted into the base hole 311. The front end of the guide rod 32 extends to the front side of the base hole 311 and is connected to the rear end of the contact head 33. The elastic connecting member 34 is arranged between the contact head 33 and the base 31, so that the guide rod 32 and the contact head 33 can be compressed and reset through the elastic connecting member 34.
[0051] In practice, the guide sleeve 1 can be securely fixed to the support structure, providing a guide path for the bushing rod 11. The bushing rod 11 is movably inserted into the guide sleeve 1. The radial floating clearance between the bushing rod 11 and the guide sleeve 1 allows the bushing rod 11 to freely move radially within a certain range. A drive device connected to the rear end of the bushing rod 11 can drive the movement of the bushing rod 11 and the bushing head 2 at the front end.
[0052] like Figure 6 、 7 As shown, during specific operation, after the workpiece 7 is fixed, the bushing 6 is fixed on the bushing press head 2, and the driving device is started. The driving device drives the bushing press head 2 forward through the bushing pressure rod 11, and the bushing press head 2 pushes the bushing 6 close to the mounting hole of the workpiece 7. In this process, if there is a radial position deviation between the bushing press head 2 and the mounting hole, when the contact head 33 contacts the components outside the mounting hole (the components here can be the workpiece 7 itself, or auxiliary components or other device components for positioning the workpiece 7), the components outside the mounting hole will apply forces of different directions and magnitudes to the contact head 33. After the force is applied, the contact head 33 will drive the guide rod 32 to produce axial movement. The axial movement of the guide rod 32 will apply forces of different directions and magnitudes to the base 31 through the elastic connecting member 34. The direction of the resultant force of this force that is finally fed back to the bushing press head 2 through the base 31 will be opposite to the direction in which the bushing press head 2 deviates from the mounting hole. For example, when the bushing press head 2 deviates to the right side of the mounting hole, the abutment head 33 on the right side of the bushing press head 2 is subjected to greater pressure than the abutment head 33 on the left side of the bushing press head 2. Therefore, a leftward resultant force is eventually fed back to the bushing press head 2 through the base 31. This leftward resultant force causes the bushing pressing rod 11 to produce a leftward radial displacement within the guide sleeve 1, thereby driving the bushing press head 2 to move leftward, and ultimately causing the bushing press head 2 to accurately carry the bushing 6 and press it into the mounting hole of the workpiece 7. When the bushing press head 2 is withdrawn from the mounting hole of the workpiece 7, the elastic connector 34 resets the guide rod 32 and the abutment head 33.
[0053] More specifically, when the bushing press head 2 presses the bushing 6 into the mounting hole of the workpiece 7, the front end of the contact head 33 first contacts the components outside the mounting hole. If the bushing press head 2 is tilted, the components outside the mounting hole will generate different pressures on the contact heads 33 at different positions. For example, when the bushing press head 2 is tilted to the left, the pressure on the left contact head 33 is greater, and the axial movement distance of the guide rod 32 is greater; the pressure on the right contact head 33 is smaller, and the axial movement distance of the guide rod 32 is smaller. The elastic connector 34 applies different amounts of elastic force to each guide rod 32 according to the displacement difference of each guide rod 32. The multiple guide rods 32 work together to achieve floating support for the bushing press head 2.
[0054] The number and location of guide rods 32 can be determined based on the specific shape of the workpiece 7 and the installation requirements. For example, for circular mounting holes with evenly distributed holes, three or more guide rods 32 can be provided, evenly distributed along the circumference of the bushing head 2 to provide balanced support during operation. For irregularly shaped workpieces 7, additional guide rods 32 can be added to locations around the mounting holes where they are subject to greater forces or are prone to deviation, to enhance support and guidance.
[0055] Servo motors can be used as the drive unit due to their precise position control and stable power output. However, in applications where high thrust is required but less demanding precision, hydraulic cylinders can also be used as the drive unit. These cylinders utilize high-pressure oil to provide powerful thrust. In applications where speed and cost are paramount, pneumatic cylinders can be used as the drive unit. These cylinders utilize compressed air to provide thrust, offering the advantages of rapid operation and low cost.
[0056] The base 31 and the bushing press head 2 can be detachably connected, for example, by a flange connection, a threaded connection, a quick-change joint connection, a clamp connection, etc.
[0057] The existing high-precision pressure head structure is complex and expensive. Adjustment is difficult when the installation position deviates, making it difficult to strike a balance between precision and cost. However, the present invention, through the floating adjustment mechanism 3, can relax the requirements for the overall precision of the equipment and reduce manufacturing costs. In actual use, even if the equipment using the present invention has certain errors, it can ensure the accurate installation of the bushing 6, greatly improving installation precision and efficiency, while also significantly reducing maintenance costs.
[0058] Example 2:
[0059] like Figure 1 、 2 As shown in , 3, 6, and 7, further, the supporting structure is a supporting frame 4, and the guide sleeve 1 is detachably connected to the supporting frame 4.
[0060] In a specific implementation, the support structure may be a support frame 4, and the guide sleeve 1 and the support frame 4 may be connected in a detachable manner such as a flange connection, a threaded connection, or a snap connection. When it is necessary to replace the guide sleeve 1, the bushing pressure rod 11, the bushing pressure head 2, and the floating adjustment mechanism 3 with different specifications to adapt to different bushing 6 installation requirements, the old guide sleeve 1, bushing pressure rod 11, bushing pressure head 2, and floating adjustment mechanism 3 can be easily removed from the support frame 4 through the above-mentioned detachable connection method, and then a new guide sleeve 1, bushing pressure rod 11, bushing pressure head 2, and floating adjustment mechanism 3 can be installed.
[0061] In addition to being installed on the support frame 4, the guide sleeve 1 can also be installed on a robotic arm, a gantry or other special fixing devices according to different specific application scenarios.
[0062] Example 3:
[0063] like Figure 1 、 4 As shown in , 6 and 7 , further, the front end of the bushing press head 2 is provided with an introduction angle 21 .
[0064] During specific implementation, the introduction angle 21 at the front end of the bushing press head 2 can be designed as a chamfered structure, such as a chamfer of 15°~45°. The introduction angle 21 not only helps the bushing press head 6 to smoothly enter the mounting hole of the workpiece 7, reducing the resistance and friction in the initial installation, but also plays a preliminary guiding role for the bushing 6. When the bushing press head 2 is close to the mounting hole, the introduction angle 21 can first contact the mounting hole, and its special shape can guide the bushing 6 to gradually align with the mounting hole. In addition to guiding the bushing 6 into the mounting hole and reducing resistance and friction, the introduction angle 21 can also disperse the pressure when the bushing 6 is pressed in. In addition to setting the introduction angle 21, the bushing press head 2 can also be set as a conical introduction portion with a gradually decreasing diameter, and the bushing 6 is guided into the mounting hole through the conical structure.
[0065] Example 4:
[0066] like Figure 4 、 6 As shown in FIG. 7 , further, there is a radial floating gap between the guide rod 32 and the base hole 311 .
[0067] During specific implementation, the radial floating clearance between the guide rod 32 and the base hole 311 allows the guide rod 32 to have a certain radial movement space in the base hole 311. The size of the clearance can be comprehensively considered based on the specific size of the bushing 6, the specific type of the workpiece 7, the guide accuracy, the floating adjustment range and the specific facilities of the structural stability. When the bushing press head 2 has a position deviation during the process of pressing the bushing 6, the contact head 33 is subjected to the force of the peripheral components of the mounting hole, which will generate a radial component force on the guide rod 32. The existence of the radial floating clearance can cause the guide rod 32 to produce radial displacement, so that the elastic connector 34 can adjust the elastic force according to the displacement of the guide rod 32, thereby adjusting the position of the bushing press head 2 and realizing automatic adjustment.
[0068] Example 5:
[0069] like Figure 4 As shown, further, the base hole 311 includes a base hole small diameter section 3111 and a base hole large diameter section 3112 from front to back, and the guide rod 32 is movably arranged in the base hole small diameter section 3111. The rear end of the guide rod 32 extends to the rear side of the base hole small diameter section 3111 and is connected to the limiting block 35. The outer diameter of the limiting block 35 is larger than the inner diameter of the base hole small diameter section 3111 and smaller than the inner diameter of the base hole large diameter section 3112.
[0070] During specific implementation, the design of the small diameter section 3111 of the base hole and the large diameter section 3112 of the base hole can limit the axial movement range of the guide rod 32 and prevent it from falling out of the base hole 311. The shape of the limit block 35 can be round, square, etc., and can be selected according to the actual installation space and force conditions. When the guide rod 32 is subjected to axial force, the guide rod 32 can move in the small diameter section 3111 of the base hole. When the contact head 33 moves away from the base 31, the limit block 35 will move with the guide rod 32. When the limit block 35 contacts the step surface of the small diameter section and the large diameter section, since the outer diameter of the limit block 35 is larger than the inner diameter of the small diameter section, it will prevent the guide rod 32 and the contact head 33 from continuing to move, thereby playing a limiting role.
[0071] If the base hole small diameter section 3111 and the base hole large diameter section 3112 are not provided, the limiting block 35 may be provided with an outer diameter greater than the base hole 311 and located outside the base hole 311. In this case, the limiting block 35 may be provided by the rear end face of the base 31.
[0072] The limit block 35 can be in the shape of a plate, connected to the rear end of the guide rod 32 by bolts, which is convenient for installation and disassembly; the limit block 35 can also be a circular ring piece, which is sleeved on the rear end of the guide rod 32 and fixed by welding or interference fit; the limit block 35 and the guide rod 32 can also be integrally formed to meet higher structural strength and reliability.
[0073] Example 6:
[0074] like Figure 4 、 6 As shown in Figures 7 and 8, further, the front end of the abutment head 33 is covered with a buffer layer.
[0075] During specific implementation, the cushion layer can not only enhance the cushioning effect, but also further improve the protection performance of the workpiece 7. The cushion layer can be made of rubber, polyurethane, plastic, felt or other flexible materials. In addition, the entire contact head 33 can also be made of the above-mentioned cushioning material.
[0076] Example 7:
[0077] like Figure 4 、 6 As shown in FIG. 7 , further, the front end of the abutting head 33 is provided with an arc chamfer.
[0078] During specific implementation, the circular chamfer not only helps the contact head 33 to transition more smoothly when in contact with the workpiece 7, reduces stress concentration, and reduces the risk of damage to the surface of the workpiece 7, but also assists in automatic centering during the installation of the device. When the contact head 33 is close to the mounting hole, the shape of the circular chamfer makes it easier to slide along the edge of the mounting hole and automatically adjust its position to achieve automatic centering. At the moment the contact head 33 contacts the workpiece 7, the contact area between the curved surface of the circular chamfer and the surface of the workpiece 7 gradually increases, so that the impact force is dispersed over a larger area, thereby reducing local stress concentration. When the contact head 33 contacts the edge of the mounting hole at a certain angle, the circular chamfer will evenly disperse the impact force, avoiding the occurrence of stress concentration points that cause damage to the workpiece 7. At the same time, during the installation of the bushing 6, if there is a certain deviation in the bushing pressure head 2, the contact between the circular chamfer and the peripheral components of the mounting hole will generate a component force that moves toward the center of the mounting hole, helping the bushing pressure head 2 to achieve automatic centering.
[0079] In addition, the entire front end of the abutment head 33 can be designed into a spherical shape, with the sphere having the same curvature in all directions, which can achieve automatic centering in a larger range and more effectively disperse the impact force, and is suitable for situations where the mounting hole position deviation is large.
[0080] Example 8:
[0081] like Figure 4 As shown, further, the abutment head 33 is threadedly connected to the guide rod 32 .
[0082] In specific implementation, an external thread can be set at the rear of the contact head 33, and an internal threaded hole can be set at the front end of the guide rod 32. During installation, the external thread of the contact head 33 is screwed into the internal threaded hole of the guide rod 32, and a tight connection is achieved by rotation; or an internal threaded hole can be set at the rear of the contact head 33, and an external thread can be set at the front end of the guide rod 32, which can also achieve the connection purpose.
[0083] Example 9:
[0084] like Figure 4 As shown, further, the elastic connecting member 34 is a compression spring, which is sleeved on the outside of the guide rod 32, with the rear end of the compression spring abutting the front side of the base 31, and the front end of the compression spring abutting the rear side of the abutting head 33.
[0085] During specific implementation, the specifications and performance of the compression spring can be selected according to the actual working conditions. For situations where a larger elastic force is required, a compression spring with a thicker wire diameter and fewer turns can be selected; for situations where the elastic force requirement is not high but a larger deformation is required, a compression spring with a thinner wire diameter and more turns can be selected. When the guide rod 32 is displaced by an external force, the compression spring will be compressed or stretched accordingly. When the bushing pressure head 2 encounters resistance and causes the guide rod 32 to move backward, the compression spring will be compressed and store elastic potential energy; when the external force is removed, the compression spring relies on its own elastic restoring force to release the stored energy, pushing the guide rod 32 and the contact head 33 back to the initial position, thereby realizing the reset function.
[0086] Depending on the specific application scenario, the elastic connecting member 34 in the present invention may be made of, in addition to a compression spring, a rubber buffer, a pneumatic spring, a hydraulic rod, an elastic plastic part, etc.
[0087] Example 10:
[0088] like Figure 1 、 4 , 6, and 7, further, the guide sleeve 1 includes a first guide sleeve 101 and a second guide sleeve 102, the bushing pressure rod 11 includes a first bushing pressure rod and a second bushing pressure rod, the bushing pressure head 2 includes a first bushing pressure head 201 and a second bushing pressure head 202, and the floating adjustment mechanism 3 includes a first floating adjustment mechanism 301 and a second floating adjustment mechanism 302;
[0089] The first bushing pressure rod is movably inserted into the first guide sleeve 101 , the front end of the first bushing pressure rod is connected to the rear end of the first bushing pressure head 201 , and the first floating adjustment mechanism 301 is sleeved on the outside of the first bushing pressure head 201 ;
[0090] The second bushing pressure rod is movably inserted into the second guide sleeve 102 , the front end of the second bushing pressure rod is connected to the rear end of the second bushing pressure head 202 , and the second floating adjustment mechanism 302 is sleeved on the outside of the second bushing pressure head 202 ;
[0091] The first floating adjustment mechanism 301 and the second floating adjustment mechanism 302 are connected via a connecting mechanism 5 .
[0092] During implementation, depending on the specific workpiece 7, the guide sleeve 1, bushing pressure rod 11, bushing pressure head 2, and floating adjustment mechanism 3 can be provided in two or more sets to accommodate the simultaneous installation of multiple bushings 6. The connecting mechanism 5 can utilize either fixed-size connecting rods and connecting plates or adjustable-size connecting rods and connecting plates. The connecting rod mechanism connects the various sets of floating adjustment mechanisms 3 to achieve synchronized motion.

[0093] In summary, the present invention can reduce the production cost of installing the bushing 6 and has a high degree of automation and high installation accuracy.
