Description

Technical Field

[0001] This invention relates to the field of automotive parts installation technology, and more specifically to a C-frame press-fitting device for vehicle frame bushings. Background Technology

[0002] Some car brackets have mounting sleeves at their ends, with bushings embedded inside. The bushings are usually pressed into the mounting sleeves by a press. After the bushings are placed, the bushings and the press head are not on the same axis. For example, although the bushings are upright, their axes are deviated from the axis of the press head, or the bushings are placed crookedly, and the bushing axes are not parallel to the axis of the press head. This will cause the bushings to bend, affecting the pressing effect and pressing efficiency.

[0003] To address this, we propose a C-frame press-fitting device for chassis bushings. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a C-frame pressing device for vehicle frame bushings. It overcomes the deficiencies of existing technologies, has a reasonable design, is easy to adjust, and solves the technical problem of bushing bending caused by the press head and bushing not being on the same axis in existing vehicle frame bushing installations.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution:

[0008] A C-frame pressing device for vehicle frame bushings, characterized in that it includes a base, a pressing mechanism, and a feeding mechanism;

[0009] The pressing mechanism includes a C-type press frame, an electric cylinder, and a pressing head. The C-type press frame is mounted on a base, the electric cylinder is mounted on the upper part of the C-type press frame, and the pressing head is mounted on the output end of the electric cylinder and can move vertically.

[0010] The feeding mechanism includes a feeding slide, a feeding drive unit, a lifting drive unit, and a positioning shaft. The feeding slide is driven by the feeding drive unit to move to the bottom of the pressure head and is driven by the lifting drive unit to perform lifting and lowering movements. The positioning shaft is installed on the press flange. The press flange includes a sleeve and a flange ring extending outward from the middle of the sleeve.

[0011] The feeding slide is equipped with a first cover plate at the mounting position of the press-fit flange. The first cover plate has a stepped hole that runs from top to bottom. The flange ring of the press-fit flange is slidably installed in the large-diameter end below the stepped hole. The upper end of the sleeve of the press-fit flange passes through the small-diameter end above the stepped hole, and the lower end of the sleeve passes through the feeding slide. There are gaps between the flange ring and the large-diameter end of the stepped hole, and between the sleeve and the small-diameter end of the stepped hole.

[0012] A leveling press plate is installed on the support plate at the bottom of the C-type press frame. A conical positioning protrusion is formed in the middle of the upper part of the leveling press plate. The plane around the positioning protrusion is a horizontal reference plane. The bottom of the sleeve abuts against the horizontal reference plane of the leveling press plate. The concave conical positioning groove in the bottom plate is positioned and matched with the positioning protrusion.

[0013] Furthermore, a second cover plate is provided between the first cover plate and the feeding slide. The first cover plate, the second cover plate, and the feeding slide are connected in sequence by bolts. A first adapter hole is formed on the second cover plate to fit the root of the sleeve with a clearance. A second adapter hole is formed on the feeding slide to fit the root of the sleeve with a clearance. The diameter of the second adapter hole is larger than the diameter of the first adapter hole.

[0014] Furthermore, the pressing mechanism includes a linear module and a straightening structure. The press is installed at the output end of the linear module and can move vertically up and down under the drive of the linear module. The straightening structure includes a connecting sleeve, straightening bars, guide bolts, and springs. The connecting sleeve is coaxially installed at the lower end of the cylinder body of the electric cylinder and extends downward. The connecting sleeve has several circumferentially distributed straightening bars. The upper part of the straightening bars extends inward to form a driving part. The inner side of the driving part has a guide slope. The guide bolt is installed on the connecting sleeve and guides the straightening bars. The spring is sleeved on the guide bolt and its two ends abut against the straightening bars and the connecting sleeve. When the press head cooperates with the guide slope of the driving part during the pressing process, the straightening bars are squeezed outward under the action of the press head to expand the opening between the straightening bars. When the press head disengages from the driving part during the pressing process, the straightening bars are squeezed inward under the action of the spring to reduce the opening between the straightening bars.

[0015] Furthermore, the inner wall of the connecting sleeve has a pair of protruding ridges corresponding to each straightening bar, and an installation groove is formed between the pairs of protruding ridges. The straightening bar is installed in the installation groove, and each installation groove is provided with a pair of guide bolts arranged from top to bottom.

[0016] Furthermore, the base is provided with a pair of press-fitting mechanisms on each of its left and right sides, spaced apart along the front-to-back direction.

[0017] Furthermore, the feeding slide is slidably mounted on the feeding machine frame via the first slide rail assembly and slides along the front-back direction of the base under the action of the first drive unit. The crossbeam of the feeding machine frame is located above the middle of the base and extends along the front-back direction of the base.

[0018] The C-type press frame is slidably mounted on the base via the second slide rail assembly and slides along the left and right directions of the base under the action of the second drive unit;

[0019] The electric cylinder is slidably mounted on the upper part of the C-type press frame via the third slide rail assembly and slides along the front-to-back direction of the base under the action of the third drive unit;

[0020] Furthermore, the first drive unit, the second drive unit, and the third drive unit all include a servo motor, a lead screw and nut pair, and a lower slide plate. The output end of the servo motor is connected to the lead screw, the lead screw and nut are fixed to the lower part of the slide plate and cooperate with the lead screw, and slide rail assemblies are installed on both sides of the slide plate.

[0021] Furthermore, casters are installed on the lower parts of both sides of the base.

[0022] (III) Beneficial Effects

[0023] This invention provides a C-frame pressing device for vehicle frame bushings, which has the following advantages:

[0024] 1. After the frame is transferred from the feeding mechanism to the pressing mechanism, the lifting drive unit lowers the feeding slide. During the lowering process of the feeding slide, the tapered positioning groove at the bottom of the pressing flange and the tapered positioning protrusion at the top of the leveling pressing plate are positioned and engaged. The bottom plane of the pressing flange is in contact with the horizontal reference plane of the leveling pressing plate, so as to achieve effective positioning of the pressing flange, positioning flange, positioning shaft and bushing installed on the positioning shaft, and prevent the axis of the bushing and the pressing head from deviating.

[0025] 2. The setting of the straightening mechanism can straighten the misaligned bushing by squeezing inward through each straightening block, and prevent the bushing and the pressure head from being out of parallel axis.

[0026] The above operations can effectively prevent bushing bending, ensure pressing effect and pressing efficiency, and are especially suitable for synchronous pressing of multi-point bushings in automotive brackets. Attached Figure Description

[0071] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0072] Example 1

[0073] See attached document Figure 1-4 A C-frame pressing device for a vehicle frame bushing includes a base 1, a pressing mechanism 2, and a feeding mechanism;

[0074] The pressing mechanism 2 includes a C-type press frame 21, an electric cylinder 22, and a pressing head 23. The C-type press frame 21 is mounted on the base 1, the electric cylinder 22 is mounted on the upper part of the C-type press frame 21, and the pressing head 23 is mounted on the output end of the electric cylinder 22 and can move vertically. By using the C-type press frame 21, during the pressing process, pressure is applied on the press frame and weight is weighed on the bottom. The forces cancel each other out, which can reduce the stress on the platform.

[0075] The feeding mechanism includes a feeding slide 311, a feeding drive unit, a lifting drive unit, and a positioning shaft 321. The feeding slide 311 is driven by the feeding drive unit to move below the pressure head 23 and is driven by the lifting drive unit to perform lifting and lowering movements (in this embodiment, the feeding slide 311 is installed on the lower slide plate 343 through a set of guide post and guide sleeve assembly 332, and the lifting drive unit is a lifting cylinder 331. Under the drive of the lifting cylinder 331, the feeding slide 311 performs lifting and lowering movements along the guide post and guide sleeve). The positioning shaft 321 is installed on the press flange 323. The press flange 323 includes a sleeve 3231 and a flange ring 3232 extending outward from the middle of the sleeve 3231.

[0076] The feeding slide 311 is equipped with a first cover plate 324 at the mounting position of the press-fit flange 323. The first cover plate 324 has a stepped hole 3241 that runs from top to bottom. The flange ring 3232 of the press-fit flange 323 is slidably installed in the large-diameter end below the stepped hole 3241. The upper end of the sleeve 3231 of the press-fit flange 323 passes through the small-diameter end above the stepped hole 3241, and the lower end of the sleeve 3231 passes through the feeding slide 311. There are gaps between the flange ring 3232 and the large-diameter end of the stepped hole 3241, and between the sleeve 3231 and the small-diameter end of the stepped hole 3241.

[0077] A leveling press plate 312 is installed on the support plate 211 at the lower part of the C-type press frame 21. A conical positioning protrusion 3121 is formed in the middle of the upper part of the leveling press plate 312. The plane around the positioning protrusion 3121 is a horizontal reference plane. The bottom of the sleeve 3231 abuts against the horizontal reference plane of the leveling press plate 312. The concave conical positioning groove of its bottom plate 3233 is positioned and engaged with the positioning protrusion 3121.

[0078] In this embodiment, the positioning shaft 321 is specifically coaxially fixed to the positioning flange 322 (the main body of the positioning flange is cylindrical). The positioning flange 322 is vertically inserted into the press-fit flange and can elastically extend and retract vertically under the action of the built-in spring (not shown in the figure, the two ends of the built-in spring abut against the bottom plate of the positioning flange and the press-fit flange respectively). Each mounting sleeve of the frame is sleeved outside the positioning flange 322 and its bottom is supported on the upper end face of the press-fit flange 323 (i.e., the upper end face of the sleeve), realizing the positioning support of the frame. Contouring blocks and positioning pins can also be added as needed for support and positioning. The positioning shaft 321 extends out of the mounting sleeve and the bushing is inserted into the positioning shaft by the operator.

[0079] In this embodiment, a second cover plate 325 is provided between the first cover plate 324 and the feeding slide 311. The first cover plate 324, the second cover plate 325 and the feeding slide 311 are connected in sequence by bolts. A first adapter hole 3251 is formed on the second cover plate 325 to fit with the root of the sleeve 3231. A second adapter hole 3111 is formed on the feeding slide 311 to fit with the root of the sleeve 3231. The diameter of the second adapter hole 3111 is larger than the diameter of the first adapter hole 3251.

[0080] In this embodiment, a pair of pressing mechanisms 2 are provided on each of the left and right sides of the base 1, spaced apart along the front and rear direction, to adapt to the scenario where the four corners of the frame need to be fitted with bushings. When the frames are different, they can be adapted by the overall feeding slide 311 and the leveling pressing plate 312. If they are the same type of frame, that is, frames of different sizes, shapes and models but all four corners need to be fitted with bushings, the installation position of the pressing flange 323 can be adjusted by setting the above-mentioned adaptation holes. Of course, pressing flanges 323 and positioning flanges 322 of different heights and inner diameters can also be replaced for adaptation, and the leveling pressing plate 312 can be adjusted synchronously.

[0081] In this embodiment, the feeding slide 311 is slidably mounted on the feeding frame via the first slide rail assembly 341 and slides along the front-back direction of the base 1 under the action of the first drive unit. The crossbeam of the feeding frame is located above the middle part of the base 1 and extends along the front-back direction of the base 1.

[0082] The C-type press frame 21 is slidably mounted on the base 1 via the second slide rail assembly and slides along the left and right directions of the base 1 under the action of the second drive unit;

[0083] The electric cylinder 22 is slidably mounted on the upper part of the C-type press frame 21 via the third slide rail assembly and slides along the front and rear direction of the base 1 under the action of the third drive unit.

[0084] The first, second, and third drive units each include a servo motor 344, a lead screw and nut assembly, and a lower slide plate 343. The output end of the servo motor 344 is connected to the lead screw, and the lead screw and nut are fixed to the lower part of the slide plate and cooperate with the lead screw. Slide rail assemblies are installed on both sides of the slide plate. (See attached diagram.) Figure 1 , 3The feeding slide 311 is installed on the lower slide plate 343. The lower two sides of the lower slide plate 343 are respectively equipped with first sliders and the lower middle of the slide plate 343 is equipped with a lead screw nut. The lower slide plate 343 is slidably supported on the first slide rail by the first sliders (the first sliders and the first slide rails form the first slide rail assembly 341). The first lead screw 342 is provided between the pair of first slide rails. The first lead screw 342 cooperates with the lead screw nut and is connected to the servo motor 344. The support for rotating the first lead screw 342 and the first guide rail (both ends) are both supported on the support frame 345.

[0085] In this embodiment, casters are installed on the lower parts of both sides of the base 1 to facilitate the overall transfer of the equipment.

[0086] Example 2

[0087] See attached document Figure 5-8 In this embodiment, the C-frame pressing equipment specifically includes a linear module (not shown in the figure) and a straightening structure 4 in its pressing mechanism 2, compared to embodiment 1. The linear module is slidably mounted on the third slide rail assembly via a slide table. The press is mounted on the output end of the linear module and can move vertically up and down under the drive of the linear module. The straightening structure 4 includes a connecting sleeve 41, straightening bars 42, guide bolts 43, and springs 44. The connecting sleeve 41 is coaxially mounted on the lower end of the cylinder body of the electric cylinder 22 and extends downward. The connecting sleeve 41 has several circumferentially distributed straightening bars 42 inside. The upper part of the straightening bars 42 extends inward to form a driving part 421. The inner side of the driving part 421 has a guide slope 422. The guide bolts 43 are installed... The guide bolt 43 is threaded to the cylinder wall of the connecting sleeve 41 and guides the straightening bar 42 (specifically, the screw of the guide bolt 43 is threaded to the cylinder wall of the connecting sleeve 41, and its head slides and guides the guide hole of the straightening bar 42 and is limited by the limiting ring protruding inside the guide hole to prevent the straightening bar from coming out). The spring 44 is sleeved on the guide bolt 43 and its two ends abut against the straightening bar 42 and the connecting sleeve 41. When the pressure head 23 cooperates with the guide inclined surface 422 of the drive part 421 during the pressing process, the straightening bar 42 is squeezed outward under the action of the pressure head 23 to expand the opening between each straightening bar 42. When the pressure head 23 disengages from the drive part 421 during the pressing process, the straightening block is squeezed inward under the action of the spring 44 to reduce the opening between each straightening bar 42.

[0088] First, the electric cylinder 22 drives the pressure head 23 to press down. The cooperation between the pressure head 23 and the guide slope 422 of the drive unit 421 pushes each straightening bar 42 outward. Second, the linear module drives the electric cylinder 22, pressure head 23 and straightening structure 4 to move down as a whole, so that the straightening bars 42 surround the bushing. Then, the electric cylinder 22 continues to drive the pressure head 23 to move down. After the pressure head 23 disengages from the drive unit 421, each straightening bar 42 retracts inward. The pressing part 422 at the lower end of the straightening bar 42 presses and limits the bushing, keeping the bushing upright. Finally, the pressure head 23 presses the bushing upright into the mounting sleeve 3231 of the frame.

[0089] In this embodiment, the inner wall of the connecting sleeve 41 is provided with a pair of protruding ridges corresponding to each straightening strip 42, and an installation groove is formed between the pairs of protruding ridges. The straightening strip 42 is installed in the installation groove, and each installation groove is provided with a pair of guide bolts 43 arranged from top to bottom.

[0090] In this embodiment, the lower part of the straightening bar 42 is also provided with a pressing part 422. Both the pressing part 422 and the driving part 421 protrude from the main body of the straightening bar 42, and both have guide slopes 422 on their upper and lower sides to facilitate the downward pressing and upward retraction of the pressing head 23. The pressing part 422 can be integrally formed with the straightening bar 42, or it can be installed separately for easy replacement and maintenance.
