A front suspension bracket machining fixture

Abstract

This invention discloses a front suspension bracket processing fixture, relating to the technical field of processing fixture equipment. It includes a protective housing, a working panel fixedly mounted on the top of the protective housing, two extension plates welded to the top of the working panel, a load-bearing support plate fixedly mounted between the tops of the two extension plates, a clamping and pressing mechanism on the top of the working panel, and a numerical feedback mechanism between opposite sides of the two extension plates. The clamping and pressing mechanism includes a support column, with a first trajectory hole pre-set inside the support column. An installation sleeve is fixedly mounted on the inner wall of the first trajectory hole. The mechanism employs a double-sided pressing method to increase the contact area between the component and the bracket surface, while the area to be processed remains suspended. Consequently, when the bracket is subjected to force at a single point, the pressure generated is insufficient to exceed the supporting force applied by the mechanism, avoiding positional displacement of the bracket during processing.

Description

Technical Field

[0001] This invention relates to the field of machining fixture equipment technology, specifically a front suspension bracket machining fixture. Background Technology

[0002] The front suspension bracket of a car is used to connect the longitudinal beam, front shock absorber, and control arm, and is fixed to the cab. Its function is to prevent the cab from tilting and to absorb shocks. Vibrations generated during the car's movement are transmitted to the cab through the shock absorber, and the performance of the front suspension bracket directly affects the comfort and safety of the entire cab.

[0003] In the prior art, such as Chinese Patent Application No. CN 209125382 U, a front suspension bracket processing fixture is disclosed, relating to the field of mechanical equipment. This fixture allows the concave surface of the front suspension bracket to be clamped onto the upper and lower parts of the support tube and adjusting tube on the support frame. Then, by holding the handle and rotating the adjusting tube on the support tube, the end faces of the adjusting tube and the support tube tightly press against the front suspension bracket to fix it in place. Bolts, nuts, and clamps are used to fix the fixing plate to a drilling machine, ensuring the opening on the side of the front suspension bracket is perpendicular to the drill bit. The drilling machine is then started, allowing the drill bit to rotate and pass through the side of the front suspension bracket, the adjusting tube, and the support tube, simultaneously drilling two coaxial mounting holes on the side of the front suspension bracket. This front suspension bracket processing fixture has a simple design, is easy to install, and can support the inner wall of the front suspension bracket, preventing the front suspension bracket from concave deformation during drilling.

[0004] However, the aforementioned patents have the following shortcomings:

[0005] The front suspension bracket, with its longitudinal beams and swing arms mounted on both sides, is used to fix the shock absorber to the vehicle body. After casting, the bracket requires further processing, such as drilling and welding. Since the bracket is made of metal, it is relatively heavy and requires specific clamps to fix it during processing to ensure the accuracy of the bracket processing. The equipment involved in the aforementioned patent improves the clamping method of traditional technology. Based on the internal structure of the bracket, the working part of the clamp can fully contact the inner wall structure of the bracket, thus providing support for the shape of the bracket during processing and preventing the bracket from denting and deforming. However, there are still some shortcomings. For example, the equipment uses a single-arm hoisting clamping method. The bracket itself is heavy and has a large lateral area. During subsequent processing, its surface is mostly subjected to single-point force. Because the contact area between the working part of the equipment and the bracket is small, when the bracket is subjected to uneven force, it is very easy for the bracket to tilt towards the force-bearing point, causing deviations in the preset processing dimensions.

[0006] Therefore, we propose a front suspension bracket machining fixture to solve the problems mentioned above. Summary of the Invention

[0007] The purpose of this invention is to provide a front suspension bracket processing fixture. Through a clamping and pressing mechanism connected to the work panel, the mechanism adopts a two-stage clamping method. The first stage is used for the initial gripping and transfer of the bracket.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] This invention, by setting up a clamping and pressing mechanism, requires the use of a designated fixture for subsequent processing of the cast front suspension bracket. This fixture, possessing both transfer and positioning capabilities, employs a two-stage clamping method. The first stage is used for initial gripping and transfer of the bracket, utilizing an electromagnetic chuck to prevent the bracket from falling. Since both the gripping component and the bracket are made of metal with relatively smooth surfaces, slight misalignment during gripping can easily cause the bracket to detach during transfer. The second stage uses a double-sided pressing method to increase the contact area between the component and the bracket surface, while the area to be processed remains suspended. Therefore, when the bracket is subjected to force at a single point, the pressure generated is insufficient to exceed the supporting force applied by the mechanism, preventing positional displacement during bracket processing. This effectively solves the shortcomings of the aforementioned patent, reduces the probability of bracket falling, and improves the accuracy of subsequent bracket processing.

[0022] This invention incorporates a numerical feedback mechanism. Since the front suspension bracket is made of metal, if the pressure on its surface exceeds the material's maximum bearing capacity, it will cause deformation of the bracket body. This mechanism can detect the pressure applied to the bracket body by the clamping components in real time, and control the downward pressure intensity of the components through the mechanism system, thereby keeping the bracket within a relatively constant pressure range and preventing the bracket from being damaged and rendered unusable.

[0023] This invention utilizes a scrap screening mechanism. Because metal materials are recyclable, the scrap with larger mass and volume generated during the reprocessing of the bracket is easier to process later. The mechanism uses mechanical transmission to continuously release high-speed airflow in the discharge pipe, which separates the smaller scrap powder particles, thereby reducing the difficulty of processing the scrap later.

A cooperating sleeve 505 is fixedly fitted onto the output end of the first pneumatic push rod 504. A set of circular holes is opened inside the cooperating sleeve 505, and electric telescopic rods 506 are fixedly inserted into the inner walls of both circular holes.

An assembly rod 508 is fixedly inserted into the inner wall of the locking sleeve 507. A support plate 509 is fixedly fitted onto the outer wall of the assembly rod 508. Both sides of the outer wall of the support plate 509 are fixedly installed with… There is a set of U-shaped connectors 510. A first inner connecting rod is fixedly inserted between the two sides of the inner wall of each of the two sets of U-shaped connectors 510. A connecting block 511 is movably sleeved on the outer wall of each first inner connecting rod. A claw 512 is fixedly installed on the outer wall of each connecting block 511. A groove 513 is opened on the top of each claw 512. A second inner connecting rod is fixedly inserted between the two sides of the inner wall of each groove 513. A first hollow sleeve 514 is movably sleeved on the outer wall of each second inner connecting rod. Two sets of second pneumatic push rods 515 are fixedly installed on the top of the pallet 509. The number of the two sets of second pneumatic push rods 515 is equal to that of the claws 512. The output end of each second pneumatic push rod 515 is fixedly inserted into the inside of the first hollow sleeve 514. An electromagnetic chuck 518 is provided at the bottom of the pallet 509.

[0041] according to Figures 1-3 As shown, each of the two sets of grippers 512 has a rubber pad 517 on its inner surface. A set of metal rods 519 is fixedly inserted into the bottom of the protective shell 1. A connecting collar 520 is fixedly sleeved between the outer surfaces of the set of metal rods 519. A forward and reverse servo motor 521 is fixedly inserted into the inner surface of the connecting collar 520. By setting the forward and reverse servo motor 521, the power to steer multiple components on the support column 501 can be provided, providing conditions for the full clamping of the bracket.

[0042] according to Figures 1-3 As shown, the top of the work panel 2 is provided with an inner open-ring groove 523, and a turntable 524 is movably arranged inside the inner open-ring groove 523. The output end of the forward and reverse servo motor 521 is fixedly connected to a first transmission rod 522. The top of the first transmission rod 522 is fixedly inserted into the inside of the turntable 524. The bottom of the support column 501 is fixedly installed on the top of the turntable 524. Utilizing the movable connection between the inner open-ring groove 523 and the turntable 524, when the forward and reverse servo motor 521 is started, it can act on the support column 501 under the pull of the turntable 524, flexibly transferring the bracket in the tray 509 to the top of the work panel 2.

[0043] according to Figure 1-2 and Figure 5 As shown, the numerical feedback mechanism 6 includes two horizontal plates 601. The outer walls of the two horizontal plates 601 are respectively welded to the inner surface of the extension plate 3. A limiting sleeve 602 is fixedly sleeved between the outer walls of the two horizontal plates 601. A pressure sensor 603 is installed inside the limiting sleeve 602. By setting the pressure sensor 603, the pressure value is detected, so as to avoid the problem that the mechanism components apply too much pressure to the bracket, which may easily cause the bracket surface to deform.

[0044] according to Figure 1-2 and Figure 5 As shown, a second track hole 604 is provided at the center of the load-bearing plate 4. An alloy tray 605 is movably installed inside the second track hole 604. A set of L-shaped frames 606 is welded to the bottom of the load-bearing plate 4. A sliding rod 607 is movably inserted inside each set of L-shaped frames 606. By utilizing the movable connection between the L-shaped frames 606 and the sliding rods 607, the alloy tray 605 can move up and down inside the second track hole 604.

[0045] according to Figure 5 As shown, the top of a set of slide rods 607 is connected to the bottom of the alloy tray 605, and a rubber seat 608 is fixedly installed on the bottom of a set of slide rods 607. An active spring 609 is welded between the top of a set of L-shaped brackets 606 and the bottom of the alloy tray 605. By setting the active spring 609, when the alloy tray 605 is in a depressed state, the active spring 609 is in a compressed state. When the pressure on the top of the second track hole 604 is removed, the reaction force generated by the slide rod 607 will restore the alloy tray 605 to its original height, thereby preventing the rubber seat 608 from pressing on the surface of the pressure sensor 603 for a long time.

[0046] according to Figure 1-3 and Figure 9 As shown, a positioning frame 610 is welded to one side of the outer wall of the work panel 2. An extension rod 611 is fixedly inserted into the inner wall of the positioning frame 610. A rectangular connector 612 is fixedly sleeved on the outer wall of the extension rod 611. A controller 613 is fixedly installed on the outer wall of the rectangular connector 612. A display screen and a set of operation keys are respectively set on the front surface of the controller 613. A wiring socket 614 is set on the top of the work panel 2. A set of information lines 615 is fixedly connected inside the wiring socket 614. The output ends of the set of information lines 615 are all connected to the wiring terminals of the controller 613. By setting the controller 613, the pressure value is received, and the pressing strength of the working parts is set in time according to the strength of the bracket material.

[0047] according to Figure 1-3 and Figure 6As shown, the scrap screening mechanism 7 includes a U-shaped pipe 701. The outer wall of the U-shaped pipe 701 is fixedly installed inside the working panel 2. The bottom of the U-shaped pipe 701 is fixedly connected to a discharge pipe 702. The outer wall of the discharge pipe 702 is fixedly connected to a second hollow sleeve head 704 and a set of diversion pipes 703. By setting the U-shaped pipe 701, the scrap generated during the processing of the bracket is collected to prevent the scrap from falling randomly and increasing the difficulty of subsequent cleaning.

[0048] according to Figure 3 and Figure 6 As shown, two connecting blocks 705 are fixedly installed at the bottom of the working panel 2. A mounting cylinder 706 is fixedly installed between the bottoms of the two connecting blocks 705. A metal bracket 707 is fixedly installed on the inner wall of the mounting cylinder 706. A drive motor 708 is fixedly inserted into the inner wall of the metal bracket 707. A second transmission rod 709 is fixedly connected to the output end of the drive motor 708. A fan blade 710 is fixedly sleeved on the outer wall of the second transmission rod 709. A set of air hoses is fixedly connected to the outer wall of the fan blade 710. The air outlet of the set of air hoses all penetrates the outer wall of the second hollow sleeve 704 and is connected to the inside of the discharge pipe 702. By setting the fan blade 710, when the drive motor 708 is started, it can drive the fan blade 710 to rotate at high speed. The high-speed airflow generated is continuously introduced into the discharge pipe 702 by the air hose, providing conditions for the screening of iron filings.

[0049] according to Figure 1-2 and Figure 7 As shown, the feed end of the U-shaped pipe 701 is fixedly connected to two material-collecting baffles 711. A rectangular groove 712 is provided on one side of the outer wall of the protective shell 1. A recycling box 713 is fixedly inserted into the inner surface of the rectangular groove 712. A partition 714 is inserted into the inside of the recycling box 713. An outer connecting plate 715 is fixedly installed on the outer surface of the recycling box 713. A handle 716 is welded to the outer surface of the outer connecting plate 715. By setting up the recycling box 713, it is used for the recycling of iron filings and powder particles. Furthermore, by installing the partition 714, the interior of the recycling box 713 can be divided into two areas, thereby preventing the two types of iron filings from mixing again after screening.

[0050] The overall mechanism achieves the following effect: first, the device is moved to the designated work area, and the bottom of the protective housing 1 is fully in contact with the ground. The device is then connected to a power source to provide energy support for multiple electrical components.

[0051] According to the placement position of the bracket, the electric telescopic rod 506 in the round hole is activated and acts on the base 516 to adjust the position of the working component of the lateral adjustment mechanism. This further opens the first pneumatic push rod 504 in the mounting sleeve 503 and acts on the cooperating sleeve 505 to adjust the height of the working component of the lateral adjustment mechanism until the tray 509 is placed on top of the bracket to be processed. Then, the electromagnetic chuck 518 is energized. Utilizing the magnetization effect of the magnetic field of the energized solenoid on the iron core inside the component, the bottom of the electromagnetic chuck 518 generates a strong adsorption force, quickly and tightly adsorbing the metal bracket onto the surface of the tray 509. Simultaneously, each second pneumatic push rod 515 on the tray 509 is activated. Through the movable connection between the first inner rod and the connecting block 511 and the second inner rod and the first hollow sleeve 514, the position gradually decreases. The angle between the gripper 512 and the pallet 509 fully grips both sides of the outer wall of the bracket. The first pneumatic push rod 504 retracts in the opposite direction, raising the height of the bracket in the pallet 509. The forward and reverse servo motors 521 in the connecting collar 520 are activated and act on the first transmission rod 522. Utilizing the movable connection between the inner open-ring groove 523 and the turntable 524, the bracket clamped at the bottom of the pallet 509 is transferred to the top of the work panel 2. The electric telescopic rod 506 is finely adjusted and aligned with the top of the load-bearing pallet 4. The first pneumatic push rod 504 is then activated to move the bracket downward. When the inner wall of the bracket is in full contact with the top of the load-bearing pallet 4, the second pneumatic push rod 515 retracts, restoring the gripper 512 to its original position and continuously pressing down on the pallet 509, finally clamping the bracket between the pallet 509 and the load-bearing pallet 4.

[0052] During the process, as the pressure on the top of the second track hole 604 increases, the height of the second track hole 604 is continuously lowered by utilizing the movable connection between the L-shaped frame 606 and the slide bar 607. Meanwhile, each rubber seat 608 gradually presses against the surface of the pressure sensor 603. The values ​​obtained are transmitted as electrical signals through the information line 615 and the internal wires of the device, and are quickly imported into the controller 613 and then displayed on the screen. At this time, the user can set the range of the pressure value according to the strength of the bracket material and control the pressing strength of the plate 509 on the top of the bracket by adjusting the extension length of the second track hole 604.

[0053] When the bracket is being drilled, as the drill bit continues to penetrate deeper into the bracket, the resulting iron filings will slide from the material collection baffle 711 into the U-shaped pipe 701 under their own gravity after the hole is formed. As the amount of iron filings inside gradually increases, they will gradually move towards the middle of the U-shaped pipe 701. At this time, the drive motor 708 in the metal bracket 707 is turned on and acts on the second transmission rod 709, driving the fan blade 710 to rotate at high speed. The high-speed airflow generated at its front end will be continuously delivered into the second hollow sleeve 704 through the hose and act on the inside of the discharge pipe 702. The iron filings that fall from the discharge pipe 702 are then screened out by the strong wind and discharged through the diversion pipe 703. Finally, both types of iron filings are collected by the recycling box 713 and separated by the partition 714.

[0054] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
