Description

Technical Field

[0001] This application relates to the field of automotive interior parts assembly equipment technology, and in particular to an automotive headliner pressing device. Background Technology

[0002] The published patent document CN220904155U discloses a pressing device for automotive headliner plastic parts, including a base and a limiting mechanism. A worktable is fixedly connected to one side surface of the base, and a lower template is fixedly connected to one side surface of the worktable. A column is connected through one end surface of the base, and a limiting mechanism is provided at one end of the base. This pressing device for automotive headliner plastic parts, through the arrangement of a fixed block, a first sliding groove, a fixed groove, a second sliding groove, a first slider, a limiting block, a threaded rod, and a nut, firstly, according to the size of the raw material, the threaded rod slides on the first sliding groove on one side surface of the fixed block, causing the threaded rod to drive the limiting block to slide. To prevent the limiting block from shifting during sliding, the limiting block is fixedly connected to the first slider, so the first slider also slides within the second sliding groove. When the position is determined, the threaded rod and the nut are threadedly connected, finally achieving a fixing effect.

[0003] In actual use, the above devices have a fixed upper mold base and lower mold base, which can only be adapted to the pressing requirements of the plastic parts of the roof of a single car model. They cannot meet the pressing requirements of the roof of different car models, and the production flexibility and economy are insufficient. Therefore, this application provides an automotive roof pressing device. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides an automotive roof pressing device that overcomes these deficiencies. The device addresses the problem that, in practical use, the upper and lower mold bases are fixed structures, which can only adapt to the pressing needs of roof plastic parts for a single vehicle model, failing to meet the pressing requirements of roofs for different models, resulting in insufficient production flexibility and economy.

[0005] To achieve the above objectives, this application provides the following technical solution: a car roof pressing device, comprising an upper beam and a base, both the upper beam and the base being equipped with a quick-release mechanism. An upper mold base is mounted on the upper beam via the quick-release mechanism, and a lower mold base is mounted on the base via the quick-release mechanism. The quick-release mechanism includes a mounting plate, which is fixedly mounted on the top of the upper mold base. Two sets of springs are mounted on both sides of the mounting plate, and a C-shaped frame is mounted on one end of each spring. A locking block is fixedly mounted inside the upper beam, and the top of the C-shaped frame is inserted into the locking block. A connecting rod is installed between the two sets of C-shaped frames, and an inverted L-shaped push rod is fixedly mounted on one side of the connecting rod. A limit mechanism is provided at one end of the inverted L-shaped push rod. A driving mechanism is mounted above the upper beam.

[0006] By adopting the above technical solution, the car roof material is placed above the lower mold base. The upper mold base is driven downward by the drive mechanism, so that the upper and lower mold bases press the material together. Depending on the pressing requirements of the car roof, appropriate upper and lower mold bases are selected. When removing them, the two sets of C-shaped frames are moved towards the upper mold base by pushing the inverted L-shaped push rod, causing the C-shaped frames to disengage from the locking blocks. After disengaging the C-shaped frames on both sides of the upper mold base from their connecting locking blocks, the upper mold base can be removed. The replacement of the lower mold base is similar. During installation, the operation is reversed: the two sets of C-shaped frames are moved towards the upper mold base by pushing the inverted L-shaped push rod, the mounting plate is inserted into the upper beam, and the inverted L-shaped push rod is released, allowing the C-shaped frames to move under the elastic action of the spring and insert into the corresponding locking blocks, completing the installation of the upper mold base. This method is beneficial for meeting the pressing requirements of different car roof models, improving production flexibility and economy.

[0007] As a preferred technical solution of this application, the limiting mechanism includes two sets of fixing plates. The limiting mechanism is provided on both sides of the upper mold base and the lower mold base. The two sets of fixing plates are fixedly installed on one side of the upper mold base. A rectangular block is fixedly installed on one side of the inverted L-shaped push rod. A fixing pin is inserted between the two sets of fixing plates and the rectangular block. A locking seat is fixedly installed on one side of one set of fixing pins. One end of the fixing pin is threadedly connected to the locking seat.

[0008] By adopting the above technical solution, after replacing the upper or lower mold base, the fixing pin is connected to the two sets of fixing plates and rectangular blocks, and the fixing pin is rotated to lock the locking seat thread, thereby completing the fixing of the inverted L-shaped push rod, improving the overall stability of the quick loading and unloading mechanism, and improving the stability of the upper and lower mold bases after installation.

[0009] As a preferred technical solution of this application, the mounting plate has storage slots on both sides, the spring is installed in the storage slot, and the size of the C-shaped frame is smaller than the size of the storage slot. The upper beam has two sets of mounting slots inside, and the two sets of mounting slots are correspondingly set with the two sets of storage slots.

[0010] By adopting the above technical solution, since the size of the C-shaped frame is smaller than the size of the storage slot, when the inverted L-shaped push rod pushes the C-shaped frame to retract into the storage slot, the C-shaped frame can be completely stored inside the storage slot, thereby allowing the mounting plate and the upper beam to be easily installed and removed.

[0011] As a preferred technical solution of this application, a magnetic absorbing sheet is fixedly installed inside the card block, and the magnetic absorbing sheet is attracted to the C-shaped frame.

[0012] By adopting the above technical solution, the magnetic absorbing piece is attracted to the end of the magnetic absorbing piece when the C-shaped frame is inserted into the card block, thereby improving the stability of the connection between the C-shaped frame and the card block.

[0013] As a preferred technical solution of this application, a pull ring is fixedly installed at the bottom end of the inverted L-shaped push rod, and a spring is installed between the bottom of the inverted L-shaped push rod and the upper mold base.

[0014] By adopting the above technical solution, a hand action point is provided when adjusting the inverted L-shaped push rod through the pull ring, and the spring can flexibly extend and retract to adapt to the position adjustment of the inverted L-shaped push rod, thus improving its practicality during use.

[0015] As a preferred technical solution of this application, the spring is provided with a telescopic guide rod inside.

[0016] By adopting the above technical solution, the telescopic guide rod plays a guiding role when the spring elastically expands and contracts, which helps to extend the service life of the spring.

[0017] As a preferred technical solution of this application, a fixing cylinder is fixedly installed at each of the four corners of the top of the base, and a spring is fixedly installed inside the fixing cylinder. A pressure rod is fixedly installed at each of the four corners of the bottom of the upper beam, and the bottom end of the pressure rod is connected to the corresponding spring.

[0018] By adopting the above technical solution, the pressing impact energy is absorbed through the cooperation of the fixed cylinder and the pressure rod, which helps to improve the pressing quality of the vehicle roof.

[0019] As a preferred technical solution of this application, the driving mechanism includes two sets of hydraulic cylinders, and the telescopic ends of the two sets of hydraulic cylinders are fixedly installed with the top of the upper beam.

[0020] By adopting the above technical solution, the synchronous pressure applied by two sets of hydraulic cylinders helps to provide uniform pressure and improves the pressing quality of the vehicle roof.

[0021] The beneficial effects of this application are:

[0022] 1. Place the car roof material above the lower mold base. Drive the upper mold base downwards via the drive mechanism, causing the upper and lower mold bases to press the material together. Select appropriate upper and lower mold bases according to the pressing requirements of the car roof model. To remove them, push the inverted L-shaped push rod to move the two sets of C-shaped frames towards the upper mold base, disengaging the C-shaped frames from the locking blocks. After disengaging the C-shaped frames on both sides of the upper mold base from their connecting locking blocks, the upper mold base can be removed. The replacement of the lower mold base is similar. During installation, simply reverse the operation: push the inverted L-shaped push rod to move the two sets of C-shaped frames towards the upper mold base, insert the mounting plate into the upper beam, and release the inverted L-shaped push rod to allow the C-shaped frames to move under the elastic action of the spring and insert into the corresponding locking blocks, completing the installation of the upper mold base. This method helps meet the pressing requirements of different car roof models, improving production flexibility and economy.

[0023] 2. After replacing the upper or lower mold base, connect the fixing pin to the two sets of fixing plates and rectangular blocks, and rotate the fixing pin to lock it with the locking seat thread, thereby completing the fixing of the inverted L-shaped push rod, improving the overall stability of the quick loading and unloading mechanism, and improving the stability of the upper and lower mold bases after installation.

Detailed Implementation

[0029] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0030] Reference Figure 1-4A car roof pressing device includes an upper beam 1 and a base 2. Both the upper beam 1 and the base 2 are equipped with a quick-release mechanism 6. An upper mold base 3 is mounted on the upper beam 1 via the quick-release mechanism 6, and a lower mold base 4 is mounted on the base 2 via the quick-release mechanism 6. The quick-release mechanism 6 includes a mounting plate 601, which is fixedly mounted on the top of the upper mold base 3. Two sets of springs 602 are mounted on both sides of the mounting plate 601. A C-shaped bracket 603 is mounted on one end of each spring 602. A locking block 604 is fixedly mounted inside the upper beam 1. The top of the C-shaped bracket 603... The connecting rod 605 is installed between the two sets of C-shaped frames 603 and inserted into the inside of the card block 604. An inverted L-shaped push rod 606 is fixedly installed on one side of the connecting rod 605. A limit mechanism 7 is provided at one end of the inverted L-shaped push rod 606. A drive mechanism 5 is installed above the upper beam 1. Storage slots 607 are opened on both sides of the mounting plate 601. A spring 602 is installed in the storage slot 607. The size of the C-shaped frame 603 is smaller than the size of the storage slot 607. Two sets of mounting slots 608 are opened inside the upper beam 1. The two sets of mounting slots 608 are correspondingly set with the two sets of storage slots 607.

[0031] The car roof material is placed above the lower mold base 4. The upper mold base 3 is driven downward by the drive mechanism 5, causing the upper mold base 3 and lower mold base 4 to press the material together. Depending on the pressing requirements of the car roof, appropriate upper mold base 3 and lower mold base 4 are selected. When removing them, the inverted L-shaped push rod 606 is pushed to move the two sets of C-shaped brackets 603 towards the upper mold base 3, disengaging the C-shaped brackets 603 from the locking blocks 604. After disengaging both C-shaped brackets 603 on both sides of the upper mold base 3 from their connecting locking blocks 604, the upper mold base 3 can be removed. The replacement of the lower mold base 4 is similar; during installation, the operation is reversed. Pushing the inverted L-shaped push rod 606 causes the two sets of C-shaped brackets 603 to move downward, disengaging the material together. The C-shaped frame 603 moves towards the upper mold base 3, inserting the mounting plate 601 into the upper beam 1. The inverted L-shaped push rod 606 is released, allowing the C-shaped frame 603 to move under the elastic action of the spring 602 and insert into the corresponding locking block 604, completing the installation of the upper mold base 3. This facilitates meeting the pressing requirements of roofs for different vehicle models and improves production flexibility and economy. Because the size of the C-shaped frame 603 is smaller than the size of the storage groove 607, when the inverted L-shaped push rod 606 pushes the C-shaped frame 603 to retract into the storage groove 607, the C-shaped frame 603 can be completely stored inside the storage groove 607, thus allowing the mounting plate 601 and the upper beam 1 to be easily installed and removed.

[0032] Reference Figure 1-3The limiting mechanism 7 includes two sets of fixing plates 701. The upper mold base 3 and the lower mold base 4 are both provided with the limiting mechanism 7. The two sets of fixing plates 701 are fixedly installed on one side of the upper mold base 3. A rectangular block 702 is fixedly installed on one side of the inverted L-shaped push rod 606. A fixing pin 704 is inserted between the two sets of fixing plates 701 and the rectangular block 702. A locking seat 703 is fixedly installed on one side of one set of fixing pins 704. One end of the fixing pin 704 is threadedly connected to the locking seat 703. A magnetic suction piece 8 is fixedly installed inside the locking block 604. The magnetic suction piece 8 is attracted to the C-shaped frame 603.

[0033] After replacing the upper mold base 3 or the lower mold base 4, the fixing pin 704 is connected to the two sets of fixing plates 701 and the rectangular block 702, and the fixing pin 704 is rotated to lock the locking seat 703, thereby completing the fixing of the inverted L-shaped push rod 606, improving the overall stability of the quick loading and unloading mechanism 6, and improving the stability of the upper mold base 3 and the lower mold base 4 after installation; when the magnetic suction piece 8 is inserted into the card block 604 by the C-shaped frame 603, the end of the magnetic suction piece 8 is attracted, which improves the stability of the connection between the C-shaped frame 603 and the card block 604.

[0035] Reference Figure 2-4 The spring 602 has a telescopic guide rod 12 inside; the drive mechanism 5 includes two sets of hydraulic cylinders 501, the telescopic ends of the two sets of hydraulic cylinders 501 are fixedly installed with the top of the upper beam 1; the telescopic guide rod 12 guides the spring 602 when it elastically expands and contracts, which helps to extend the service life of the spring 602; the synchronous pressure applied by the two sets of hydraulic cylinders 501 helps to provide uniform pressure and improve the pressing quality of the roof of the vehicle.

[0036] Working principle: The car roof material is placed above the lower mold base 4. The upper mold base 3 is driven downward by the drive mechanism 5, so that the upper mold base 3 and the lower mold base 4 press the material together. Depending on the pressing requirements of the car roof, appropriate upper mold base 3 and lower mold base 4 are selected. When removing them, the two sets of C-shaped brackets 603 are moved towards the upper mold base 3 by pushing the inverted L-shaped push rod 606, causing the C-shaped brackets 603 to disengage from the locking blocks 604. After disengaging the C-shaped brackets 603 on both sides of the upper mold base 3 from the connecting locking blocks 604, the upper mold base 3 can be removed. The replacement of the lower mold base 4 is the same. In principle, during installation, the operation is reversed. Push the inverted L-shaped push rod 606 to move the two sets of C-shaped frames 603 towards the upper mold base 3, insert the mounting plate 601 into the upper beam 1, release the inverted L-shaped push rod 606 to allow the C-shaped frame 603 to move under the elastic action of the spring 602 and insert into the corresponding locking block 604 to complete the installation of the upper mold base 3. After replacing the upper mold base 3 or the lower mold base 4, connect the fixing pin 704 to the two sets of fixing plates 701 and the rectangular block 702, and rotate the fixing pin 704 to lock it with the locking seat 703, thereby completing the fixing of the inverted L-shaped push rod 606.
