Description

Technical Field

[0001] This invention relates to the field of chassis bushing assembly technology, and more specifically to a multi-station chassis bushing pressing equipment. Background Technology

[0002] In the manufacturing process of automobile frames, bushings need to be pressed into multiple pre-designed locations on the frame, which involves multi-station bushing press-fitting operations. The distribution of the holes for the bushings to be pressed into the frame is complex, and their specific positions and angles are determined by the specific frame design, without a uniform standard. This means that on the same frame, bushings may be arranged in multiple locations on one side or distributed on both sides, and the pressing axis of each hole may also form a certain angle with the frame reference plane. This diversity and uncertainty in hole layout places high demands on the adaptability and flexibility of the bushing press-fitting equipment.

[0003] Currently, the common bushing pressing methods are mainly divided into two categories: horizontal pressing and vertical pressing.

[0004] Horizontal press fitting uses a horizontally placed press, and the press head can only apply pressure in the horizontal direction, lacking posture adjustment capabilities. To accommodate holes at different positions and angles, a frame-type fixture must be specially designed for each type of frame, resulting in a complex structure and high manufacturing costs. During use, the entire fixture, equipped with the frame, must be repeatedly lifted, moved, and realigned manually or using lifting equipment to complete the press fitting of bushings at different positions one by one; or only the frame itself can be lifted and placed, but multiple sets of fixtures corresponding to different holes must be provided and changed as needed. The frames are large and heavy, and the repeated lifting and placing is labor-intensive. Each insertion requires strict alignment of the hole and the press head; even a slight deviation will cause the bushing to be misaligned or damaged, resulting in time-consuming and labor-intensive rework.

[0005] Vertical press-fitting uses a lifting device to lift and rotate the entire vehicle frame into an upright position, then a vertical press head applies downward force to press the bushing in. Compared to horizontal presses, vertical presses are more flexible in handling holes at different angles and positions. However, the height space required for erecting the vehicle frame is usually several times its own dimensions, making site requirements demanding. During the lifting process, the vehicle frame sways due to its own weight, leading to inaccurate positioning, requiring additional guiding and positioning mechanisms, further increasing equipment costs. Operators must complete bushing filling and position confirmation from a high position, making assembly difficult and precision hard to guarantee.

[0006] In summary, among the existing frame bushing pressing technologies, horizontal pressing is limited by the frame tooling design and repeated lifting and lowering operations. Multi-station pressing is inefficient, labor-intensive, difficult to center, and prone to pressing defects. Vertical pressing requires the entire frame to be lifted and flipped, which occupies a large space, and the positioning during the lifting process is inaccurate. It requires the addition of a high-cost guiding mechanism, and the high-level operation is difficult and the accuracy is hard to guarantee.

[0007] Therefore, to solve the above problems, a multi-station frame bushing pressing equipment is needed that can take into account the spatial convenience of horizontal layout and the flexible adaptability of multiple angles and positions, avoid repeated lifting or overall hoisting of the frame, reduce the intensity of operation and site requirements, and significantly improve pressing accuracy and yield. Summary of the Invention

[0008] In view of this, the purpose of the present invention is to overcome the defects in the prior art and provide a multi-station frame bushing pressing equipment that can take into account the spatial convenience of horizontal layout and the flexible adaptability of multiple angles and positions, avoid repeated lifting or overall hoisting of the frame, reduce the intensity of operation and site requirements, and significantly improve pressing accuracy and yield.

[0009] The multi-station frame bushing pressing equipment of the present invention includes a support mechanism and a pressing mechanism; the support mechanism includes a turntable that is driven to shift and adjust its posture, and the turntable is provided with a mounting position for detachably fixing the frame tooling; the pressing mechanism includes a pressing head that is driven to shift and is driven to perform single-degree-of-freedom extension and retraction.

[0010] In use, the frame fixture is fixed to the turntable via the mounting position. The turntable adjusts the position of the frame on the frame fixture by shifting and adjusting the posture. The pressure head is driven to move to the preset position so that the pressure head is aligned with the bushing mounting position on the frame to be pressed in. The pressure head presses the bushing in along its extension and retraction direction.

[0011] Furthermore, the mounting position is a universal mounting interface located on the turntable. Different specifications of frame fixtures share the same mounting position, and the frame fixtures are fixed to the mounting position by conventional detachable connections such as bolts and locating pins. Of course, multiple sets of this mounting position can be provided to correspond to different frame fixtures, which will not be elaborated here.

[0012] Furthermore, the pressing mechanism also includes a functional frame and a supporting member; the pressing head is located on the functional frame, the functional frame is driven to shift and is driven to perform single-degree-of-freedom extension and retraction to drive the pressing head; the supporting member is slidably disposed on the functional frame and is driven to move closer to or away from the pressing head along the extension and retraction direction of the functional frame.

[0013] Furthermore, the frame tooling is provided with a bushing pre-positioning assembly, which includes a pre-positioning seat and a pre-positioning head, and the pre-positioning seat and the pre-positioning head are arranged opposite to each other on both sides of the hole position on the frame where the bushing is to be pressed.

[0014] In use, the bushing is pre-assembled on the pre-positioning head, the pre-positioning seat abuts against one end of the corresponding hole, and the pre-positioning head is driven to pre-position the bushing within the hole.

[0015] During press-fitting, the supporting member is driven to support the prepositioning seat, the press head presses against the prepositioning head, and the functional frame is driven to move toward the bushing mounting position, thereby driving the press head to press the bushing into the bushing mounting position.

[0016] Furthermore, the bushing pre-positioning assembly also includes a first power source for driving the pre-positioning seat and a second power source for driving the pre-positioning head.

[0017] Furthermore, the pre-pressure applied by the prepositioning head is maintained continuously during the press-fitting process.

[0018] Furthermore, the supporting mechanism also includes a first base and a first moving frame slidably connected to the first base, the first moving frame being driven to reciprocate along a first direction;

[0019] The turntable is mounted on the first motion frame and is driven to rotate around the vertical axis to adjust its posture.

[0020] Furthermore, the pressing mechanism also includes a support frame and a first driving member. The support frame is provided with a slide rail arranged along a first direction. The functional frame is slidably disposed on the slide rail. The first driving member is disposed on the support frame and drives the functional frame to reciprocate along the slide rail.

[0021] Furthermore, the pressing mechanism also includes a second base and a second moving frame, the second moving frame being slidably connected to the second base and driven to reciprocate along a second direction;

[0022] The support frame is slidably connected to the second motion frame and is driven to reciprocate along a third direction;

[0023] The first direction, the second direction, and the third direction are perpendicular to each other.

[0024] Furthermore, the abutment is slidably disposed on the functional frame and is driven by the second driving member to move closer to or away from the pressure head along the first direction.

[0025] Furthermore, the driving end of the second driving member passes through the functional frame and is guided by the functional frame to form a driving abutment member.

[0026] Furthermore, the functional frame is in the shape of a U-shape with the opening facing downwards, and the two ends of the U-shaped functional frame are respectively provided with a pressure head and a supporting member.

[0027] Furthermore, the functional frame is located in the space above the turntable.

[0028] The beneficial effects of the present invention are as follows: The multi-station frame bushing pressing equipment disclosed in the present invention can complete the corresponding transformation of several bushing pressing positions in a horizontal layout by means of the displacement and posture adjustment capability of the turntable; and in general, the pressing head only needs to be moved to the corresponding set position for pressing, without the need to lift and place the frame, hoist and flip, or frequently change tooling, which greatly reduces the labor intensity and site space requirements of frame bushing pressing, and significantly improves pressing accuracy and yield.

[0041] Figure 12 This is a schematic diagram of the frame tooling of the present invention. Figure 2 . Detailed Implementation

[0042] Figures 1 to 12As shown in the figure, the multi-station frame bushing pressing equipment in this embodiment includes a support mechanism 1 and a pressing mechanism 2. The support mechanism 1 includes a turntable 101 that is driven to move and adjust its posture. The turntable 101 is provided with a mounting position for detachably fixing the frame tooling. The pressing mechanism 2 includes a pressing head 201 that is driven to move and is driven to perform single-degree-of-freedom extension and retraction.

[0043] In use, the frame fixture is fixed to the turntable 101 through the mounting position. The turntable 101 adjusts the position and orientation of the frame fixture to place the frame in a preset position with a set orientation. The pressure head 201 is driven to move to the preset position so that the pressure head 201 is aligned with the bushing mounting position on the frame to be pressed. The pressure head 201 presses the bushing in along its extension and retraction direction.

[0044] The support mechanism 1 integrates displacement and attitude adjustment functions, allowing adjustment of the vehicle frame attitude located on the support mechanism 1 at a single workstation, thus enabling individual adaptation of multiple bushing mounting positions distributed at different locations and angles on the vehicle frame. The support mechanism 1 can be composed of a turntable combined with a multi-degree-of-freedom displacement platform, or it can be constructed by combining a multi-degree-of-freedom attitude adjustment platform with a drive platform and other structural combinations, depending on the intended function, which will not be elaborated further here.

[0045] After the pressing mechanism 2 moves the pressing head 201 to the preset position, the pressing action can be completed simply by the pressing head 201 providing a single degree of freedom of extension and retraction. The overall structure is compact, eliminating the need for a separate press for each hole or repeated lifting and lowering of the chassis. The method of driving the pressing head 201 to move can include a multi-degree-of-freedom platform or a robotic arm with a set path, preferably coordinating with the movement and attitude adjustment of the turntable 101 to press the chassis bushing. Further details will not be provided here. The method of driving the extension and retraction of the pressing head 201 can be any existing motor or power cylinder, preferably achieving the intended purpose. Further details will not be provided here.

[0046] This solution differs from existing technologies where horizontal presses require repeated lifting and lowering of the chassis or tooling, and vertical presses require the entire chassis to be hoisted and rotated. Through the displacement and attitude adjustment capabilities of the turntable 101, several bushing pressing positions can be changed in a horizontal layout. Furthermore, the press head 201 only needs to be moved to the set position for pressing, eliminating the need for lifting and lowering the chassis, hoisting and rotating, and frequent tooling changes. This significantly reduces the labor intensity and space requirements for chassis bushing pressing, and significantly improves pressing accuracy and yield.

[0047] like Figure 11 and Figure 12 The diagram shows the structure of two types of frames and their corresponding tooling. When using them, you only need to replace the frame tooling on the turntable 101. For the bushing press-fitting of the bushing mounting position, you only need to adjust the frame position and posture accordingly. The overall operation is simple.

[0048] In this embodiment, the mounting position is a universal mounting interface 1011 located on the turntable 101. Different specifications of frame tooling share the same mounting position. The mounting position adopts a universal interface design, so when changing frame products, only the corresponding frame tooling needs to be disassembled and replaced; there is no need to replace the turntable 101 or recalibrate the reference. Only the frame support part needs to be adapted, resulting in high changeover efficiency and significantly reduced tooling costs. The frame tooling is fixed to the mounting position using conventional detachable connections such as bolts and locating pins. Of course, multiple sets of this mounting position can be provided to correspond to different frame tooling, which will not be elaborated further here.

[0049] In this embodiment, the pressing mechanism 2 further includes a functional frame 202 and a supporting member 203. The pressing head 201 is located on the functional frame 202. The functional frame 202 is driven to shift and is driven to extend and retract with a single degree of freedom to drive the pressing head 201. The supporting member 203 is slidably disposed on the functional frame 202 and is driven to move closer to or away from the pressing head 201 along the extension and retraction direction of the functional frame 202. The pressing head 201 and the supporting member 203 are integrated on the same functional frame 202. The overall extension and retraction of the functional frame 202 can drive the pressing head 201 to complete the pressing action. At the same time, the supporting member 203 can slide independently relative to the functional frame 202, flexibly adjusting the distance between itself and the pressing head 201 to adapt to the positional requirements of different workstations. Furthermore, through the cooperation of the two ends of the pressing head 201 and the supporting member 203, a synergistic effect can be formed on both sides of the hole during pressing, resulting in more stable force application and higher pressing accuracy.

[0050] In this embodiment, the frame tooling is provided with a bushing pre-positioning assembly, which includes a pre-positioning seat 301 and a pre-positioning head 302. The pre-positioning seat 301 and the pre-positioning head 302 are arranged opposite to each other on both sides of the hole on the frame where the bushing is to be pressed. In use, the bushing is pre-assembled on the pre-positioning head 302, the pre-positioning seat 301 abuts against one end of the corresponding hole, and the pre-positioning head 302 is driven to pre-position the bushing within the hole. During pressing, the abutment member 203 is driven to abut the pre-positioning seat 301, the pressing head 201 presses against the pre-positioning head 302, and the functional frame 202 is driven to move toward the bushing mounting position, causing the pressing head 201 to press the bushing into the bushing mounting position. The bushing is first pre-positioned at the bushing mounting position on the frame by a pre-positioning component. Then, the final pressing is completed by the coordinated force applied by the holding member 203 and the two ends of the pressing head 201. Pre-positioning ensures the accurate initial position of the bushing in the hole, effectively avoiding problems such as skewing, jamming, and misalignment caused by direct pressing. The pre-positioning step significantly improves the first-pass yield of bushing pressing and reduces rework and material waste. The bushing pre-positioning component, including the pre-positioning seat 301 and the pre-positioning head 302, corresponds to existing components used in the prior art for bushing pre-pressing. It is advisable to select them in groups according to the bushing specifications to complete the intended function, which will not be elaborated further here.

[0051] In this embodiment, the bushing pre-positioning assembly further includes a first power source for driving the pre-positioning seat 301 and a second power source for driving the pre-positioning head 302. The pre-positioning seat 301 and the pre-positioning head 302 are mounted on the chassis tooling and are each driven by an independent power source. This allows for independent control of both sides of the bushing mounting position on the chassis, facilitating precise adjustment of the pre-positioning stroke and applied force according to the hole position and bushing size. This adapts to the pre-positioning requirements of bushings of different specifications and improves the accuracy of bushing assembly on the chassis. Specifically, both the first and second power sources are cylinders in this solution to meet preset power requirements. In actual applications, they can also be hydraulic cylinders or electric push rods, or other power drive components, which will not be elaborated further here.

[0052] In this embodiment, the pre-pressure applied by the pre-positioning head 302 is maintained continuously during the pressing process. The pre-pressure acts continuously throughout the pressing process, superimposing with the pressing force. This ensures the bushing is consistently and stably constrained throughout the pressing process, preventing it from retracting or tilting during the final pressing stage. This guarantees the bushing maintains the correct posture throughout its entire stroke from pre-positioning to full pressing, eliminating deviations caused by intermediate state changes and further improving pressing consistency and yield.

[0053] In this embodiment, the supporting mechanism 1 further includes a first base 102 and a first motion frame 103 slidably connected to the first base 102, the first motion frame 103 being driven to reciprocate along a first direction; as Figure 1 As shown, the first direction is the transverse direction. The first base 102 is fixed in a set position. The first moving frame 103 is driven by a lead screw motor to reciprocate along the first direction on the first base 102. The first base 102 has a first moving frame slide rail that supports and guides the first moving frame 103. The lead screw motor is hidden inside the first base 102 and located at the bottom of the first moving frame 103. The turntable 101 is located on the first moving frame 103 and is driven to rotate around the vertical axis to adjust its posture. The turntable 101 is driven by a motor and gear transmission system in the prior art, and can be locked at any angle in the horizontal direction to adapt to the assembly of frame bushings at different angles. The two work together to realize the position and angle adjustment of the frame in the horizontal plane, taking into account both the spatial convenience of the horizontal layout and the flexible adaptability to multiple angles and positions. The structure of the support mechanism 1 in this solution is simpler and has reliable transmission characteristics. Compared with the multi-degree-of-freedom turntable 101, it has better structural reliability and can reliably guarantee the accuracy of bushing pressing. The rotary table 101 can be driven by a direct motor drive or a chain drive, etc., which can achieve the intended purpose, and will not be elaborated here.

[0054] In this embodiment, the pressing mechanism 2 further includes a support frame 204 and a first driving member 205. The support frame 204 is provided with a slide rail arranged along a first direction. The functional frame 202 is slidably mounted on the slide rail. The first driving member 205 is mounted on the support frame 204 and drives the functional frame 202 to reciprocate along the slide rail. The slide rail and the first moving frame 103 are arranged in the same direction, so that the sliding direction of the functional frame 202 is consistent with the feed direction of the frame. The pressing action and the workpiece displacement are completed in the same straight line direction, resulting in the shortest movement path, a compact structure, and high force transmission efficiency as the pressing force is collinear with the movement direction. The advantage of the slide rail being arranged along the first direction is that when the supporting mechanism 1 moves along the first direction to change different pressing positions, the relative movement of the functional frame 202 and the frame is coordinated in the same straight line direction, eliminating the need for additional lateral offset compensation and improving the efficiency of multi-position switching.

[0055] In this embodiment, the support frame 204 is a horizontally placed "T" shape. Its top horizontal section is driven to shift, and its bottom vertical section is used to mount the functional frame 202. A triangular stiffening plate is also provided between the top horizontal section and the bottom vertical section to ensure the overall structural stability. A slide rail for guiding the functional frame 202 is arranged at the bottom of the support frame 204. The functional frame 202, located at the bottom of the support frame 204, is driven to reciprocate by a first driving member 205, which drives the pressure head 201. The first driving member 205 is a power cylinder, also a pneumatic cylinder, with its power end connected to a lug extending from the side of the functional frame 202. The first driving member 205 can also be a hydraulic cylinder or a motor, depending on the desired purpose, and will not be elaborated further here.

[0056] In this embodiment, the pressing mechanism 2 further includes a second base 206 and a second moving frame 207, the second moving frame 207 being slidably connected to the second base 206 and driven to reciprocate along a second direction; as Figure 1 As shown, the second direction is the longitudinal direction. The second base 206 is fixed in a set position. The second motion frame 207 is driven by a lead screw motor to reciprocate along the second direction on the second base 206. The second base 206 has a second motion frame 207 slide rail that supports and guides the second motion frame 207. The lead screw motor is located between the top of the second base 206 and the bottom of the second motion frame 207.

[0057] In this embodiment, the second motion frame 207 is generally a vertical rectangular frame, and the support frame 204 is slidably connected to the second motion frame 207 and is driven to reciprocate along a third direction; as shown Figure 1As shown, the third direction is the height direction. The support frame 204 is driven by a lead screw motor to reciprocate along the third direction on the second motion frame 207. The front side of the second motion frame 207 has a support frame slide rail for supporting and guiding the support frame 204. The lead screw motor is hidden inside the second motion frame 207 and located at the rear of the second motion frame 207. The first direction, the second direction, and the third direction are perpendicular to each other. The pressing mechanism 2 realizes independent movement in three orthogonal directions through the three-stage motion frame. Together with the translation and rotation of the supporting mechanism 1, the whole system constitutes a multi-degree-of-freedom positioning system, which can flexibly adapt to the spatial position changes of each hole on the frame and achieve precise alignment without manual adjustment. The movement in each direction is independently controlled and uncoupled, which simplifies the control logic and facilitates automated pressing through a CNC system.

[0058] In this embodiment, the abutment 203 is slidably disposed on the functional frame 202 and is driven by the second driving member 208 to move closer to or further away from the pressure head 201 along the first direction. The abutment 203 is controlled by an independent driving member, and the distance between it and the pressure head 201 can be precisely adjusted on the functional frame 202 along the pressing direction to adapt to changes in the distance between the two sides of different hole positions. The driving method is simple and the response speed is fast.

[0059] In this embodiment, the driving end of the second driving member 208 passes through the functional frame 202 and is guided by the driving support member 203. The driving end passes through the functional frame 202 and is guided by the functional frame 202 itself, eliminating the need for an additional guide support structure. It utilizes the existing structure of the functional frame 202 to achieve dual functions, resulting in high structural integration and reliable guiding accuracy. Specifically, the second driving member 208 consists of a conventional motor and a drive screw that drives the motor via a gear set. The motor housing is fixed at one end of the functional frame 202. The drive screw passes through the functional frame 202 and connects to the support member 203. The functional frame 202 has a support member 203 slide rail that guides the support member 203.

[0060] In this embodiment, the functional frame 202 is a U-shaped structure with its opening facing downwards. Each end of the U-shaped functional frame 202 is respectively equipped with a pressure head 201 and a supporting member 203. The downward-facing U-shaped opening, with the pressure head 201 and supporting member 203 at each end, forms a pressing space that spans the frame from above during use, facilitating the frame's entry and exit from below. The structure is symmetrical and the force is balanced. The side containing the pressure head 201 is closer to the frame tooling location, thus reducing the frame's travel distance. The supporting member 203 has a slide rail arranged on the opposite bottom surface of the U-shaped opening, working in conjunction with the drive screw passing through the functional frame 202 to provide dual guidance for the supporting member 203, ensuring pressing accuracy and reducing the frequency of bushing pressing defects due to deviations.

[0061] In this embodiment, the functional frame 202 is located above the turntable 101. The functional frame 202, arranged above the turntable 101, forms a layered layout with the supporting mechanism 1, allowing the pressing action to be completed above the vehicle frame. This does not occupy the operating space around the turntable 101, facilitating manual filling of bushings and observation of the pressing process. Unlike vertical presses that require the vehicle frame to be hoisted and erected, occupying several times the height of the frame, this solution features a horizontally layered layout, requiring only slightly more height than the vehicle frame itself, thus offering greater site adaptability.

[0062] In this embodiment, during the pressing operation, the corresponding specification of the frame fixture is first fixed to the turntable 101 through the universal installation interface 1011, and the frame is placed on the frame fixture. The bushing is manually pre-assembled onto the prepositioning head 302. The prepositioning seat 301 and the prepositioning head 302 are driven to move relative to each other. The prepositioning seat 301 abuts against one end of the hole, and the prepositioning head 302 prepositions the bushing within the hole. The pre-pressure is maintained throughout the pressing process. Subsequently, the turntable 101 adjusts the frame posture by shifting the first motion frame 103 and rotating itself around the vertical axis so that the bushing installation position to be pressed is in the preset position. At the same time, the second motion frame 207 of the pressing mechanism 2 shifts longitudinally, the support frame 204 shifts in the height direction, and the functional frame 202 slides in the first direction, driving the pressing head 201 to move to the preset position so that the pressing head 201 is aligned with the bushing installation position. The abutment 203 is driven to abut the prepositioning seat 301, and the functional frame 202 is driven to move toward the bushing mounting position, causing the pressure head 201 to fully press the bushing from the prepositioning position into the bushing mounting position. After the first bushing is pressed, the turntable 101 switches to the next bushing mounting position again by shifting and / or rotating, repeating the above alignment and pressing actions until all bushings on the frame are pressed.

[0063] Throughout the pressing process, the chassis remains fixed to the same fixture on the turntable 101, eliminating the need for lifting, hoisting, flipping, or frequent changes of fixtures or presses. The turntable 101's displacement and attitude adjustment capabilities, combined with the multi-degree-of-freedom motion of the pressing mechanism 2, enable the one-to-one adaptation and continuous pressing of bushing installation positions at multiple locations and angles on the chassis. The pre-positioning component ensures the accurate initial position of each bushing before final pressing, while the coordinated force applied at both ends guarantees the stability and precision of the pressing process. This solution, with its compact structure and horizontal layout, achieves efficient and high-precision pressing of multi-station bushings, significantly reducing labor intensity and space requirements, and substantially improving yield and production efficiency.

[0064] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
