[0016] Step 2: The movement of the C-shaped plate drives the hollow tube to move. When the hollow tube moves, the processing table provides support for the hollow tube through the slide groove. The hollow tube transfers the support force provided by the processing table to the C-shaped plate. The C-shaped plate affected by the support force moves more smoothly.

[0017] Step 3: The movement of the C-shaped plate drives the movement of the T-shaped rod, and the movement of the T-shaped rod drives the rubber plate to move. The No. 1 corrugated groove of the rubber plate contacts the auto parts during movement and stops moving;

[0019] The present invention provides a fastening and installation device for automobile accessories, which has the following beneficial effects:

[0020] (1) In the automobile parts fastening and installation device, when the hollow tube moves, the processing table provides support for the hollow tube through the slide groove, and provides necessary support for the C-shaped plate through the processing table, so as to ensure that the rubber plate always maintains a stable movement during the clamping process, and avoid the automobile parts from loosening due to unbalanced clamping force, thereby ensuring the stability of the automobile parts welding processing. At the same time, the L-shaped block is limited and stops moving. The L-shaped block contacts the limit groove, ensuring that the rubber plate stably clamps the automobile parts, while preventing the rubber plate from excessively squeezing the surface of the automobile parts, thereby improving the efficiency of fastening and installation.

[0021] (2) In the automobile parts fastening and installation device, the rotation of the rotating rod drives the baffle to rotate, so that the baffle releases the obstruction to the rectangular groove. The baffle automatically opens after the rubber plate stably clamps the automobile parts, which not only improves the work efficiency, but also effectively prevents the operator from operating the bottom of the automobile parts before they are stably clamped. At the same time, the second corrugated groove of the friction block is in close contact with the inner wall of the mounting plate. After the processing is completed, the baffle can automatically reset to the initial position, which effectively improves the efficiency of continuous processing. At the same time, the provision of the friction block can enhance the stability of the baffle in blocking the rectangular groove.

[0022] (3) In the automotive parts fastening and installation device, the bent elastic sheet quickly recovers and collides with the tooth block to generate vibration. The elastic sheet collides with multiple tooth blocks on the comb plate to generate continuous vibration, which helps to improve the smoothness of the overall movement and ensures that the L-shaped block can stably contact the limit groove to perform the limit work. At the same time, the grip rod is separated from the circular groove, so that the limit imposed by the grip rod on the comb plate is released. The position of the comb plate can be quickly changed through simple operation, which is convenient for the operator to choose whether to enable the comb plate according to actual operation needs, which helps to improve the applicability of the comb plate in different scenarios.

[0034] A slide groove is provided on one side of the processing table 2 close to the hollow tube 9, and the circumferential surface of the hollow tube 9 contacts the inner wall of the slide groove. A No. 1 corrugated groove is provided on one side of the rubber sheet 7 away from the T-shaped rod 6. The processing table 2 provides necessary support for the C-shaped plate 5 to ensure that the rubber sheet 7 always maintains a stable movement during the clamping process.

[0035] A method for installing an automobile accessory fastening and installation device, using the above-mentioned automobile accessory fastening and installation device, comprises the following steps:

[0036] Step 1: Place the auto parts on the top of the processing table 2, start the electric push rod 4, and the output end of the electric push rod 4 moves to drive the C-shaped plate 5 to move toward the rectangular groove;

[0037] Step 2: The C-shaped plate 5 moves to drive the hollow tube 9 to move. When the hollow tube 9 moves, the processing table 2 provides support for the hollow tube 9 through the slide groove. The hollow tube 9 transmits the support force provided by the processing table 2 to the C-shaped plate 5. The C-shaped plate 5 affected by the support force moves more smoothly.

[0038] Step 3: The C-shaped plate 5 moves to drive the T-shaped rod 6 to move, and the T-shaped rod 6 moves to drive the rubber plate 7 to move, and the No. 1 corrugated groove of the rubber plate 7 contacts the automobile accessory during movement and stops moving;

[0039] Step 4: The C-shaped plate 5 continues to move and squeeze the No. 1 spring 8. The deformed No. 1 spring 8 exerts a reaction force on the rubber plate 7. The rubber plate 7 affected by the reaction force exerts a gradually increasing clamping force on the auto parts, thereby achieving stable clamping of the auto parts by the rubber plates 7 on both sides of the processing table 2.

[0040] When the present embodiment is working, before the automobile parts are welded, the automobile parts are placed on the top of the processing table 2, and the bottom of the automobile parts contacts the inner wall of the rectangular groove during movement, and the electric push rod 4 is started. The output end of the electric push rod 4 moves to drive the C-shaped plate 5 to move in the direction of the rectangular groove, and the C-shaped plate 5 moves to drive the hollow tube 9 to move in the direction of the rectangular groove. When the hollow tube 9 moves, the processing table 2 provides support for the hollow tube 9 through the slide groove, and the hollow tube 9 transmits the supporting force provided by the processing table 2 to the C-shaped plate 5. The C-shaped plate 5 affected by the supporting force moves more smoothly, and at the same time, the C-shaped plate 5 moves more smoothly. The movement of the C-shaped plate 5 drives the T-shaped rod 6 to move away from the electric push rod 4, and the movement of the T-shaped rod 6 drives the rubber plate 7 to move away from the electric push rod 4. The No. 1 corrugated groove of the rubber plate 7 contacts the auto part during movement and stops moving, so that the C-shaped plate 5 continues to move to squeeze the No. 1 spring 8, and the No. 1 spring 8 is squeezed and deformed. The deformed No. 1 spring 8 exerts a reaction force on the rubber plate 7. The rubber plate 7 affected by the reaction force exerts a gradually increasing clamping force on the auto part, thereby realizing that the rubber plates 7 on both sides of the processing table 2 can stably clamp the auto part. The processing table 2 provides necessary support for the C-shaped plate 5 to ensure that the rubber plate 7 always maintains a stable movement during the clamping process to prevent the auto parts from loosening due to unbalanced clamping force. When the C-shaped plate 5 continues to move, it also drives the hollow tube 9 to move. The movement of the hollow tube 9 drives the telescopic rod 10 to move toward the rubber plate 7. The spherical surface of the telescopic rod 10 contacts the inclined surface of the rubber plate 7 during the movement. The inclined surface exerts a gradually increasing resistance on the moving spherical surface. The telescopic rod 10 moves downward under the influence of the resistance. The telescopic rod 10 squeezes the No. 2 spring 11 during the movement. , the No. 2 spring 11 is squeezed and deformed, and at the same time, the telescopic rod 10 moves to drive the L-shaped block 12 to move downward. The L-shaped block 12 contacts the inner wall of the limiting groove during movement, and the second inclined surface of the L-shaped block 12 continues to move and fits the inner wall of the limiting groove. The L-shaped block 12 stops moving due to the limit imposed by the processing table 2, causing the hollow tube 9 and the C-shaped plate 5 to stop moving. The L-shaped block 12 contacts the limiting groove to ensure that the rubber plate 7 stably clamps the automotive accessories while preventing the rubber plate 7 from excessively squeezing the surface of the automotive accessories, thereby improving the efficiency of fastening and installation.

[0041] See also Figure 1-Figure 7On the basis of the above embodiment, another embodiment of the present invention further includes a protective device and an auxiliary device; the protective device includes a carrying plate 131, a rotating rod 132, a baffle 133, a stop plate 134, a cylindrical rod 135, a third spring 136, a contact sheet 137, a long plate 138 and a friction block 139, the carrying plate 131 is fixedly passed through the inner and outer walls of the processing table 2, the rotating rod 132 rotates and passes through the inner and outer walls of the carrying plate 131, the baffle 133 is fixedly installed on the circumferential surface of the rotating rod 132, and the stop plate 134 is fixedly installed on the rotating rod 13 2, the cylindrical rod 135 slides through the side of the mounting plate 131 close to the hollow tube 9, the third spring 136 is arranged between the cylindrical rod 135 and the mounting plate 131, the contact piece 137 is fixedly mounted on the side of the cylindrical rod 135 away from the third spring 136, the long plate 138 is fixedly mounted on the circumferential surface of the cylindrical rod 135, the friction block 139 is fixedly mounted on the surface of the abutment plate 134, the shape of the contact piece 137 is set to be arc-shaped, and it automatically opens after the rubber plate 7 stably clamps the auto parts through the baffle 133, which effectively improves the work efficiency.

[0042] A spiral spring is arranged between the rotating rod 132 and the mounting plate 131, and an arc surface is provided at the bottom of the long plate 138. The friction block 139 itself is elastic. By arranging the spiral spring, it is also effectively prevented from the operator operating the bottom of the auto part before it is stably clamped.

[0043] The surface of the mounting plate 131 is provided with a plurality of circular grooves, and the side of the friction block 139 away from the abutment plate 134 is provided with a second corrugated groove, which contacts the inner wall of the mounting plate 131. The friction block 139 can enhance the stability of the baffle 133 in blocking the rectangular groove.

[0044] The auxiliary device includes a hollow plate 141, a convex rod 142, a No. 4 spring 143, a disc 144, an elastic sheet 145, a comb plate 146 and a gripping rod 147. The hollow plate 141 is fixedly passed through the inner and outer walls of the mounting plate 131, the convex rod 142 slides through the inner and outer walls of the hollow plate 141, the No. 4 spring 143 is arranged between the convex rod 142 and the hollow plate 141, the disc 144 is fixedly installed on the side of the convex rod 142 away from the hollow plate 141, the elastic sheet 145 is fixedly installed on the circumferential surface of the convex rod 142, the comb plate 146 slides through the side of the hollow plate 141 close to the circular groove, the gripping rod 147 slides through the top of the comb plate 146, and the bottom of the gripping rod 147 contacts the inner wall of the circular groove. The position of the comb plate 146 can be quickly changed through simple operation, so that the operator can choose whether to enable the comb plate 146 according to actual operation requirements.

[0045] The elastic sheet 145 is shaped like a "V", and a second arc surface is provided on one side of the elastic sheet 145 close to the comb plate 146. The elastic sheet 145 collides with the multiple teeth on the comb plate 146 to generate continuous vibration, which helps to improve the smoothness of the overall movement.

[0046] When the present embodiment is working, the circumferential surface of the hollow tube 9 contacts the inner concave surface of the contact piece 137 during movement, so that the movement of the hollow tube 9 drives the contact piece 137 to move in the direction of the No. 3 spring 136, and the movement of the contact piece 137 drives the cylindrical rod 135 to move in the direction of the No. 3 spring 136. The cylindrical rod 135 squeezes the No. 3 spring 136 during movement, and the No. 3 spring 136 is squeezed and deformed. At the same time, the movement of the cylindrical rod 135 drives the long plate 138 to move in the direction of the No. 3 spring 136. The arc surface of the long plate 138 contacts the surface of the abutment plate 134 during movement. The movement of the long plate 138 drives the abutment plate 134 to rotate in the direction away from the contact piece 137, and the abutment plate 134 rotates in the direction away from the contact piece 137. The rotation of the rotating rod 132 drives the deformed friction block 139 to rotate in the direction away from the contact piece 137. The deformed friction block 139 is separated from the contact surface of the mounting plate 131 during the movement, so that the deformed friction block 139 returns to its original state under the action of its own elasticity. At the same time, the rotation of the abutment plate 134 drives the rotating rod 132 to rotate in the direction away from the contact piece 137. The rotating rod 132 stretches the spiral spring during the rotation. The spiral spring is deformed by the stretching. At the same time, the rotation of the rotating rod 132 drives the baffle 133 to rotate in the direction away from the rectangular groove, so that the baffle 133 releases the obstruction of the rectangular groove and automatically opens after the rubber plate 7 stably clamps the automobile accessories. It not only improves work efficiency, but also effectively prevents operators from operating the bottom of the auto parts before they are stably clamped. After the auto parts are processed, the hollow tube 9 performs a reset operation, so that the deformed No. 3 spring 136 recovers and drives the cylindrical rod 135 to move toward the contact piece 137. The movement of the cylindrical rod 135 drives the long plate 138 to move toward the contact piece 137. The long plate 138 gradually reduces the pressure applied to the abutment plate 134 during the movement, so that the deformed volute spring recovers and drives the rotating rod 132 to rotate toward the contact piece 137. The rotation of the rotating rod 132 drives the baffle 133 to rotate upward. The baffle 133 exerts pressure on the rectangular groove during the rotation. The rotation of the rotating rod 132 drives the abutment plate 134 to rotate toward the contact sheet 137, and the rotation of the abutment plate 134 drives the friction block 139 to rotate toward the contact sheet 137. The second corrugated groove of the friction block 139 contacts the inner wall of the carrying plate 131 during movement, and the carrying plate 131 squeezes the moving friction block 139. The friction block 139 is squeezed and deformed, so that the second corrugated groove is in close contact with the inner wall of the carrying plate 131. The baffle plate 133 can automatically reset to the initial position after the processing is completed, which effectively improves the efficiency of continuous processing. At the same time, the friction block 139 can enhance the stability of the baffle plate 133 in blocking the rectangular groove.

[0047] When the long plate 138 moves toward the grip 147, it contacts the disc 144, so that the long plate 138 moves and drives the disc 144 to move toward the grip 147. The disc 144 moves and drives the convex rod 142 to move toward the grip 147. The convex rod 142 stretches the No. 4 spring 143 during the movement. The No. 4 spring 143 is stretched and deformed. At the same time, the convex rod 142 moves and drives the elastic sheet 145 to move toward the grip 147. The arc surface 2 of the elastic sheet 145 contacts the tooth block of the comb plate 146 during the movement, and the movement continues. The elastic sheet 145 is bent by the resistance exerted by the tooth block, and the elastic sheet 145 stores energy in the bending. When the arc surface 2 is separated from the tooth block, the bent elastic sheet 145 quickly recovers and collides with the second tooth block to generate vibration. Then the elastic sheet 145 repeats the above movement and collides with multiple tooth blocks to generate vibration. The comb plate 146 transmits the vibration generated by the continuous collision to the contact sheet 137, and the contact sheet 137 transmits the vibration to the hollow tube 9, so that the L-shaped block 12 fits the limit groove more smoothly. The collision of the multiple tooth blocks on the upper and lower parts produces continuous vibration, which helps to improve the smoothness of the overall movement and ensure that the L-shaped block 12 can stably contact the limiting groove to perform the limiting work. When the elastic sheet 145 does not need to contact and collide with the comb plate 146, the grip rod 147 is held and moved upward. The grip rod 147 is separated from the surface in contact with the circular groove during the movement, so that the limit imposed by the grip rod 147 on the comb plate 146 is released, and the grip rod 147 is pushed to move away from the hollow plate 141. The movement of the grip rod 147 drives the comb plate 146 to move away from the elastic sheet 145. 45. When the comb plate 146 moves to the specified position, the control handle 147 moves downward. The handle 147 contacts the inner wall of the circular groove during the movement, so that the handle 147 limits the comb plate 146 moved to the specified position. At the same time, the elastic sheet 145 does not contact the tooth blocks of the comb plate 146 during the movement. The position of the comb plate 146 can be quickly changed through simple operation, which is convenient for the operator to choose whether to enable the comb plate 146 according to the actual operation requirements, which helps to improve the applicability of the comb plate 146 in different scenarios.
