Description

Technical Field

[0001] The invention relates to the field of automobile component assembly, in particular to a bolt assembly device for a buffer block. Background Art

[0002] A car's tailgate is a safety device that protects the rear of the vehicle. It not only contributes to the aesthetics of the rear of the car, but also serves as a safety feature. First, during driving, bumpy roads can cause the tailgate to collide with the car body, requiring a buffer to reduce force and noise. Second, the gap between the tailgate and the car body requires an adjustable and waterproof buffer.

[0003] The present invention relates to assembling a bolt with a metal gasket on a car tailgate buffer block. The existing assembly method is to manually insert the metal gasket into the bolt and then insert the bolt into the semi-finished car tailgate buffer block to complete the assembly process. Figure 1 As shown, a mounting hole is provided on the surface of the buffer block 03, and the gasket 01 and the bolt 02 are assembled in the mounting hole. The current processing method has high labor costs, low assembly efficiency, and there are problems such as wrong assembly and missing assembly.

[0004] Designing a mechanical mechanism to assemble the buffer block bolt presents the following challenges: Before the bolt is assembled to the buffer block, a gasket structure must be pre-assembled, with the gasket's outer diameter matching the bolt's nut's. Therefore, when assembling the bolt and gasket through the mechanical structure, how can the gasket be pre-installed in place? Furthermore, the outer circumference of the bolt's screw shaft is smooth. Therefore, after the gasket is inserted into the bolt's screw shaft, there is no corresponding force between the gasket and the bolt to maintain the assembled state. Therefore, how can the bolt and gasket be moved and installed with the buffer block?

[0005] In view of the above problems, the designers of the present invention have finally developed the present invention's "bolt assembly device for buffer block" after long-term research and development to solve the problems existing in the prior art. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to provide a bolt assembly device for a buffer block, which can realize the pre-assembly of gaskets and bolts and press-fitting them to the buffer block, and the whole process is mechanized and automated.

[0007] The technical solution adopted by the present invention to solve the above technical problems is: a bolt assembly device for a buffer block, including a bolt clamping component, a fixing tool for installing the buffer block, and a pre-installed disk connected to a feeding device, wherein a plurality of mounting seats are provided on the pre-installed disk, the top surface of the mounting seat is provided with a groove adapted to the gasket structure, the bottom surface of the groove is provided with a placement hole for inserting the screw rod of the bolt, a first notch is provided on the outer side surface of the mounting seat to connect the groove and the placement hole, a second notch is provided horizontally at the lower part of the placement hole, the second notch passes through the front and rear sides of the mounting seat, a first signal transmitter and a second signal transmitter are provided above the pre-installed disk, a signal receiving component is provided correspondingly on the outer periphery of the pre-installed disk, the first signal transmitter transmits a light beam through the first notch from the bottom surface of the groove, the second signal transmitter transmits a light beam through the second notch, the gasket and the bolt are transported to the mounting seat through the feeding device to complete the assembly, and the clamping component clamps the assembled bolts and presses them into the buffer block of the fixing tool.

[0008] A further preferred embodiment of the present invention is as follows: the feeding device includes a gasket conveying assembly and a bolt conveying assembly.

[0009] A further preferred embodiment of the present invention is as follows: station one, station two and station three are spaced apart on the periphery of the pre-installed disk, and station one, station two and station three correspond to the gasket conveying assembly, the bolt conveying assembly and the fixing tooling respectively; the signal receiving assembly includes a first signal receiver and a second signal receiver, and the first signal receiver and the second signal receiver are located at station one and station two respectively.

[0010] A further preferred solution of the present invention is that a detection head is also provided on the workstation 1, and the detection head extends toward the mounting seat on the pre-installed disk. When the mounting seat moves to correspond to the workstation 1, the detection head is attached to the top surface of the mounting seat.

[0011] A further preferred embodiment of the present invention is as follows: the gasket conveying assembly conveys the gasket into the groove of the mounting seat corresponding to station one, the bolt conveying assembly inserts the bolt into the mounting seat corresponding to station two, and the pre-installed disk rotates to drive the mounting seat through station one, station two, station three and then back to station one.

[0012] A further preferred solution of the present invention is that the clamping assembly is installed on a track through a vertical cylinder, and the clamping assembly can move back and forth between the workstation three and the fixed tooling along the track.

[0013] A further preferred embodiment of the present invention is as follows: the clamping assembly includes a bracket, a chuck and a horizontal cylinder; the bracket is provided with an arc-shaped slot; the chuck can be movably mounted in the arc-shaped slot of the bracket; and the horizontal cylinder drives the chuck to move along the arc-shaped slot.

[0014] A further preferred embodiment of the present invention is that a groove is provided at the bottom of the chuck, an electromagnet is installed in the groove, a notch is provided on the left wall of the groove, and the electromagnet is conductive and can act on the bolt and the gasket to absorb the bolt and the gasket.

The pre-installed tray is equipped with multiple mounting seats, each with a groove on its top surface for receiving the gasket. A first notch connects the groove and the placement hole. A first signal transmitter transmits a light beam from the bottom surface of the groove into the first notch. This means that if a gasket is not installed or not properly seated within the mounting seat's groove, the light beam from the first signal transmitter will be received by the signal receiving assembly. If the receiving assembly cannot receive the light beam from the first signal transmitter, it indicates that the gasket is properly seated. A placement hole is provided on the bottom surface of the groove for the bolt's shank to be inserted. Below the placement hole, a second notch is provided horizontally, extending through the front and rear sides of the mounting seat. A second signal transmitter transmits a light beam through the second notch. This means that if a bolt is not properly seated, the light beam from the second signal transmitter will be received by the signal receiving assembly. If the receiving assembly cannot receive the light beam from the second signal transmitter, it indicates that the bolt is properly seated. This ensures that the bolt and gasket are properly seated within the pre-installed tray. The gasket and bolt are transported to the mounting seat by a feeding device to complete the assembly, and the clamping assembly clamps the assembled bolts and presses them into the buffer block of the fixing fixture. The present invention can realize the pre-assembly of gaskets and bolts and press-fitting them into the buffer block, and the whole process is mechanized and automated.

[0025] The present invention will be described in detail below with reference to the accompanying drawings.

[0026] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figures 2 to 6 As shown: the bolt assembly equipment of the buffer block includes a bolt clamping component 1, a fixing tool 2 for installing the buffer block, and a pre-loaded disk 3 connected to a feeding device. A plurality of mounting seats 4 are provided on the pre-loaded disk 3. The top surface of the mounting seat 4 is provided with a groove 5 adapted to the gasket structure. The bottom surface of the groove 5 is provided with a placement hole 6 for inserting the screw rod of the bolt. A first slot 10 is provided on the outer side surface of the mounting seat 4 to connect the groove 5 and the placement hole 6. A second slot 7 is horizontally provided at the lower part of the placement hole 6. The second slot 7 passes through the front and rear sides of the mounting seat 4. A first signal transmitter 8 and a second signal transmitter 9 are provided above the pre-loaded disk 3. A signal receiving component is correspondingly provided on the outer periphery of the pre-loaded disk 3. The first signal transmitter 8 transmits a light beam from the bottom surface of the groove 5 into the first slot 10, and the second signal transmitter 9 transmits a light beam through the second slot 7. The gasket and the bolt are transported to the mounting seat 4 through the feeding device to complete the assembly. The clamping component 1 clamps the assembled bolts and presses them into the buffer block of the fixing tool 2.

[0028] The feeding device includes a gasket conveying assembly and a bolt conveying assembly 11, which are not fully drawn in the figure. The gasket conveying assembly and the bolt conveying assembly 11 can be completed by using some existing structural equipment. Both of them are not the structures to be protected by the present invention and will not be expanded here. Station one, station two and station three are set at intervals on the periphery of the pre-installed disk 3. Station one, station two and station three correspond to the gasket conveying assembly, the bolt conveying assembly 11 and the fixed tooling 2 respectively. The signal receiving assembly includes a first signal receiver 12 and a second signal receiver 13. The first signal receiver 12 and the second signal receiver 13 are located at station one and station two respectively. The gasket conveying assembly conveys the gasket to the mounting seat 4 corresponding to station one, and the first signal transmitter 8 and the first signal receiver 12 check whether the bolt is installed in place. If it is installed in place, the mounting seat 4 will move to station two, and the bolt conveying assembly 11 will convey the bolt to the station, and the second signal transmitter 9 and the second signal receiver 13 will check whether the bolt is installed in place.

[0029] The gasket conveying assembly conveys the gasket to the groove 5 of the mounting seat 4 corresponding to station one, and the bolt conveying assembly 11 inserts the bolt into the mounting seat 4 corresponding to station two. The pre-installed disk 3 rotates and drives the mounting seat 4 through station one, station two, station three and then back to station one.

[0030] Station 1 is also equipped with a detection head 14, which extends toward the mounting seat 4 on the pre-loaded tray 3. When the mounting seat 4 moves to correspond with station 1, the detection head 14 contacts the top surface of the mounting seat 4. The detection head 14 is installed at station 1 to detect whether the bolts assembled in the previous round have been removed from the mounting seat 4 that has moved to this station, thus completing the entire bolt and gasket assembly and transportation cycle.

[0031] The gripping assembly 1 is mounted on a track 15 via a vertical cylinder, and the gripping assembly 1 can move back and forth between the workstation 3 and the fixed tooling 2 along the track 15 .

[0032] The clamping assembly 1 includes a bracket 21 , a chuck 16 and a horizontal cylinder 17 . The bracket 21 is provided with an arcuate slot 18 . The chuck 16 is movably mounted in the arcuate slot 18 of the bracket 21 . The horizontal cylinder 17 drives the chuck 16 to move along the arcuate slot 18 .

[0033] The bottom of the chuck 16 is provided with a groove 5, within which an electromagnet is mounted. A notch is provided on the left side wall of the groove 5. The electromagnet conducts electricity, acting on and attracting the bolt and gasket. The gasket and bolt involved in the present invention are made of materials that can be attracted by magnets, such as iron-containing materials. Therefore, the action of the chuck 16 ensures that the gasket is located on the outer periphery of the bolt's screw.

[0034] The fixed fixture 2 is provided with a directional movable pressure plate 19 that acts on the periphery of the buffer block mounting hole. The right side of the pressure plate 19 is connected to an upright pull plate 20. A roller structure is provided on the top of the pull plate 20. An inclined plate 22 is provided on the right bottom of the bracket 21. When the bracket 21 is pressed down, it will drive the inclined plate 22 to act on the roller structure of the pull plate 20. The downward pressing bracket 21 will drive the pressure plate 19 to the right. When the present invention is pressed down with the bolt aligned with the buffer block mounting hole, the downward pressing clamping assembly 1 will drive the pressure plate 19 to move to the right, fully exposing the buffer block mounting hole for bolt press installation. When the clamping assembly 1 is lifted up, the pressure plate 19 will also move to the left and return to its initial state, ensuring the stability of the buffer block.

[0035] A waist-shaped groove is vertically defined on the upper portion of the chuck 16. A horizontal cylinder 17 is connected to the waist-shaped groove of the chuck 16. Operation of the horizontal cylinder 17 drives the chuck 16 along the arc-shaped notch 18 of the bracket 21, away from the surface of the buffer block. The present invention uses an electromagnet to attract bolts and washers. After power is removed, the electromagnet retains residual magnetism. To ensure that the chuck 16 does not remove the bolts or washers when it recovers, the present invention incorporates a pre-recovery action: the horizontal cylinder 17 operates to drive the chuck 16 away from the surface of the buffer block in a gentle, close-to-the-surface motion.

[0036] The present invention realizes the pre-assembly of the gasket and the bolt and the press-fitting to the buffer block by ingenious structural design, and the whole process is mechanized and automated.
