[0025] The present invention is further described below in conjunction with specific examples. It should be understood that the following examples are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0026] like Figure 1 to Figure 6 As shown, a flexible tooling for assembling automobile accessories is provided according to a preferred embodiment of the present invention, comprising: a base plate 1, a support leg 2, a flexible adaptive mechanism 3, a reset cylinder 4, a reset cylinder mounting plate 5, a reset mechanism 6, a reset mechanism mounting plate 7, a flexible support block 8, and a steel wire rope with a sheath 40.

Among them, the combination of the reset mechanism 6 and the steel wire rope 40 with a jacket transmits the power output by the reset cylinder 4 to the flexible adaptive mechanism 3, and the reset cylinder 4 is the power source for realizing the reset of the flexible adaptive mechanism 3; the flexible support block 8 is installed in the middle position of the upper part of the base plate through the second mounting hole 8-1. The flexible support block 8 is flexible and will not scratch the paint surface of the bumper. It can be compressed and deformed when subjected to force.

[0028] See 2~ Figure 4 The figure shows a schematic diagram of the structure of the flexible adaptive mechanism 3, which provides adaptive assembly support for products with different profiles, and is the core invention of the present invention. The flexible adaptive mechanism 3 includes: an L-shaped quick-release bolt 9, an L-shaped connecting block 10, a fifth connecting hole 10-1, a fifth mounting hole 10-2, a roller 11, a T-shaped connecting seat 12, a first connecting plate 13, a roller shaft 14, a stepped shaft 15, a third mounting hole 15-1, a linear bearing 16, a guide rod 17, a locking sleeve 18, a limiting sleeve 19, a nitrogen spring shaft 20, a locking assembly 21, a limiting shaft 22, a first support seat 23, a fourth mounting hole 23-1, an arc-shaped waist hole 23-2, a second support seat 24, a fixing plate 25, a first mounting hole 25-1, a connecting support plate 26, a first connecting support plate hole 26-1, a second connecting support plate hole 26-2, a third connecting support plate hole 26-3, and a fourth connecting support plate hole 26-4.

[0029] Among them, the first support seat 23, the second support seat 24 and the fixed plate 25 are fixed to each other to form a support frame, and the fixed plate 25 is provided with a first mounting hole 25-1 for connecting it with the base plate 1, and the first support seat 23 and the second support seat 24 are vertically fixed to the two ends of the fixed plate 25 through connecting holes (not shown) provided on the surface in contact with the fixed plate 25; the first support seat 23 is provided with a fourth mounting hole 23-1 and an arc-shaped waist-shaped hole 23-2, wherein the fourth mounting hole 23-1 is used to install the stepped shaft 15, and the arc-shaped waist-shaped hole 23-2 is the prerequisite for realizing the rotation of the connecting seat support plate 26 within a certain arc range, The second support seat 24 is provided with a mounting hole (not shown) which is the same as the fourth mounting hole 23-1; the stepped shaft 15 is a stepped shaft, and the smaller diameter end of the stepped shaft 15 is clearance-matched with the fourth mounting hole 23-1, and the cross-section of the larger diameter end of the stepped shaft 15 is provided with holes 15-1 and 15-2, and the hole 15-1 is a countersunk hole, and a bolt is passed through the hole 15-1 to be connected to the threaded hole set on the end face of the connecting support plate 26 to realize the consolidation of the stepped shaft 15 and the connecting support plate 26, and the larger diameter end is respectively fastened to the two ends of the connecting support plate 26 by bolts, and the smaller diameter end of the stepped shaft 15 is coaxially matched with the fourth mounting hole 23-1.

[0030] The connecting support plate 26 is respectively provided with a first connecting support plate hole 26-1, a second connecting support plate hole 26-2, a third connecting support plate hole 26-3, and a fourth connecting support plate hole 26-4. The guide rod 17 is respectively installed in the first connecting support plate holes 26-1 and 26-4 through a linear bearing 16. The function of the linear bearing 16 is to allow the guide rod 17 to slide freely along the first connecting support plate hole 26-1. The first connecting plate 13 is installed on the upper top surface of the two guide rods 17 through bolts. The lower side of each guide rod 17 is provided with a limit sleeve 19 for limiting the axial movement range of the guide rod 17. The nitrogen spring shaft 20 is arranged in the second connecting support plate hole 26-2 with clearance fit. The two locking sleeves 18 arranged along the nitrogen spring shaft 20 and distributed on both sides of the connecting support plate 26 lock the nitrogen spring shaft 20 on the connecting support plate 26; the upper end of the nitrogen spring shaft 20 is connected to the first connecting plate 13 through a T-shaped connecting seat. It should be understood that the nitrogen spring shaft 20 can also be replaced by another spring shaft, that is, a common spring can also achieve this function on a plain shaft. The limit shaft 22 is arranged in the third connecting support plate hole 26-3 with clearance fit, and the first connecting plate 13 is connected to the upper bottom surface of the limit shaft 22 by bolts. The locking assembly 21 is fixed to the side of the connecting support plate 26 by bolts.

[0031] The L-shaped connecting block 10 is provided with a fifth connecting hole 10-1 and a fifth mounting hole 10-2. The L-shaped connecting block 10 is fixed to the first connecting plate 13 via the fifth connecting hole 10-1. The L-shaped shape can make the roller shaft 14 closer to the product and thus make the roller 11 closer to the product, thereby avoiding the risk of the connecting support plate 26 contacting / touching the product due to the small diameter of the roller 11. The number of L-shaped connecting blocks 10 is at least two, and the more the number, the more it can prevent the roller shaft 14 from being deformed by force.

[0032] The roller shaft 14 is installed in the fifth mounting hole 10-2, and the roller 11 is installed on the roller shaft 14. The roller 11 can rotate freely on the roller shaft 14, so that when the bumper contacts the roller 11, there is rolling friction, which prevents the roller from scratching the paint of the bumper. The outer contour of the roller 11 is covered with a coating layer with lower hardness that can prevent the paint surface of the bumper from being scratched. Polyurethane material is preferred, and the number of rollers 11 can be arbitrary.

[0033] The L-shaped quick-release bolt 9 passes through the arc-shaped waist-shaped hole 23-2 set on the first support seat 23, and is threadedly connected with the third mounting hole 15-1 set on the stepped shaft 15 and provided with internal threads. The arc-shaped waist-shaped hole 23-2 is an arc-shaped hole set with the axis of the fourth mounting hole 23-1 as the axis and must be arc-shaped, because when the stepped shaft 15 connected to the connecting support plate 26 rotates along the fourth mounting hole 23-1, the L-shaped quick-release bolt 9 rotates along with it, and this arc-shaped movement space is required. The L-shaped quick-release bolt 9 can be adjusted by adjusting the matching depth with the threaded hole 15-1 set on the stepped shaft 15 to achieve the L-shaped quick-release bolt 9 and the side of the first support seat 23 (the stepped shaft 15 is tightened) or separated (the stepped shaft 15 can rotate). When working, it is tightened by the L-shaped quick-release bolt 9, and when necessary, the L-shaped quick-release bolt 9 can be loosened to achieve the rotation of the stepped shaft 15 to achieve the adjustment of the support angle of the bumper product by the flexible adaptive mechanism 3.

[0034] The axes of the limiting shaft 22 , the nitrogen spring shaft 20 and the guide rod 17 are parallel to each other and are in the same plane.

The connecting rod 21-4 passes through the connecting rod floating waist groove 21-3-1 set on the pulley bracket 21-3 and is bolted to the connecting rod connecting hole 21-6-2 set on the pawl 21-6; the connecting rod spring 21-5 is installed on the connecting rod 21-4, and the connecting rod spring 21-5 is respectively restricted by the pawl 21-6 and the pulley bracket 21-3 in the two directions of axial movement of the connecting rod 21-4 and is in a compressed state. In the natural state, the connecting rod spring 21-5 will give the pawl 21-6 a reaction force, so that the pawl 21-6 has a tendency to rotate clockwise along the pawl shaft 21-7 and engage with the ratchet 22-2 set on the limit shaft 22.

[0037] See also Figure 5, is a schematic diagram of the structure of the reset cylinder 4 and the reset mechanism 6, including: reset cylinder 4, cylinder piston rod 4-1, reset cylinder mounting plate 5, reset mechanism mounting plate fixing hole 5-1; reset mechanism mounting plate 7, reset mechanism mounting plate fixing hole 7-1, fixed plate 31, fixed plate locking hole 31-1, first wire rope threading hole 31-2, wire rope locking hole 31-3, fixed plate guide shaft 34, fixed plate guide shaft step 34-1, 30 fixed plate guide shaft bracket, second wire rope threading hole 30-1, fixed plate guide shaft bracket fixing hole 30-2, guide shaft hole 30-3, guide shaft spring 33. Among them, the cylinder piston rod 4-1 is not connected to any structure, and only when the cylinder piston rod 4-1 of the control cylinder is extended, it will give an axial force to the fixed plate guide shaft step 34-1 to make the fixed plate guide shaft 34 move axially.

[0038] The fixing plate guide shaft bracket 30 is provided with a second wire rope threading hole 30-1, a fixing plate guide shaft bracket fixing hole 30-2, and a guide shaft hole 30-3 whose diameter is smaller than the guide shaft spring 33; the reset mechanism mounting plate 7 for mounting the fixing plate guide shaft bracket 30 is bolted to the bottom plate 1 through the reset mechanism mounting plate fixing hole 7-1 provided on the reset mechanism mounting plate 7; the fixing plate guide shaft bracket 30 is bolted to the reset mechanism mounting plate 7 through the fixing plate guide shaft bracket fixing hole 30-2; the fixing plate guide shaft 34 is provided with a fixing plate guide shaft step 34-1 whose diameter is larger than the guide shaft spring 33, and the guide shaft spring 33 is threaded on the fixing plate guide shaft 34 The fixed disk guide shaft 34 is installed in the guide shaft hole 30-3 and can slide freely along the axial direction; the fixed disk 31 is installed on the fixed disk guide shaft 34 and locked by the fixed disk locking hole 31-1; in the natural state, the axial movement of the guide shaft spring 33 along the fixed disk guide shaft 34 is restricted by the step 34-1 of the fixed disk guide shaft and the fixed disk guide shaft bracket 30 and is in a compressed state, then the fixed disk 31 has a tendency to move downward along the axial direction of the fixed disk guide shaft 34, and in the natural state, the fixed disk 31 contacts the lower half of the fixed disk guide shaft bracket 30, and the guide shaft spring 33 makes the fixed disk guide shaft 34 have a tendency to move downward, and the fixed disk 31 limits the range of this axial movement.

[0039] The reset cylinder mounting plate 5 is L-shaped and is mounted on the support leg 2 through the reset mechanism mounting plate fixing hole 5 - 1 . The reset cylinder 4 is mounted on the reset cylinder mounting plate 5 through bolts.

[0040] refer to Figure 6The steel wire rope 40 with a jacket is a common steel wire rope combination consisting of a steel wire rope 40-1 and a steel wire rope jacket 40-2. The steel wire rope 4-1 is a steel wire rope with a circular cross-section made of a metal material with good tensile resistance and flexibility. The steel wire rope jacket 40-2 is a circular hollow metal tube that is resistant to extrusion force, flexible, and has a smooth inner wall. The steel wire rope 4-1 passes through the steel wire rope jacket 40-2. When the head end 40-2-1 of the steel wire rope jacket 40-2 is fixed, and then axial force is applied to the steel wire rope 4-1, the steel wire rope 4-1 can move relative to the steel wire rope jacket 40-2 along the force application direction. The function of the steel wire rope 40 with a jacket is to drive the rotation of the ratchet 21-6 after the output force of the reset cylinder 4 is converted by the reset mechanism 6 and transmitted by the steel wire rope 40 with a jacket. The function of the metal jacket is, on the one hand, to provide the steel wire rope 40-1 with a path that can be bent freely and smoothly, and on the other hand, to protect the steel wire rope 40-1 and prevent the steel wire rope 40-1 from being damaged by friction and the like.

[0041] refer to Figure 1 to Figure 6 After one end of the steel wire rope 40 with a sheath passes through the second steel wire rope lead-in hole 30-1 and the first steel wire rope lead-in hole 31-2 in sequence, a locking bolt (not shown) is screwed into the steel wire rope locking hole 31-3 with an internal thread radially arranged along the fixed plate 31 to lock the steel wire rope; the other end of the steel wire rope with a sheath passes through the pawl bracket hole 21-8-1 and the pulley 21-1 in sequence, and is locked in the connecting rod hole 21-4-1 arranged on the connecting rod 21-4 by a bolt (not shown); wherein, the metal sheath of the steel wire rope with a sheath starts from the connecting rod hole 21-4-1 and ends at the second steel wire rope lead-in hole 30-1.

[0042] refer to Figure 1 to Figure 7 The operation process of one embodiment of the flexible tooling is described as follows:

[0043] S1: Control the reset cylinder 4 so that the cylinder piston rod 4-1 is in a retracted state, and the first connecting plate 13 equipped with the L-shaped connecting block has a tendency to move along the axial direction of the limit shaft 22 toward the roller 11 side under the action of the nitrogen spring shaft 20. However, at this time, under the action of the guide shaft spring 33 and the connecting rod spring 21-5, the ratchet teeth 21-6-1 and the ratchet teeth 22-2 on the limit shaft 22 are in a meshing state, and the limit shaft 22 can move in one direction (the first connecting plate 13 moves to the side away from the installation roller 11) after receiving the force applied in the axial direction;

[0044] S2: According to the contour characteristics of the first automobile bumper 100 to be assembled, the depth of the threaded connection between the L-shaped quick-release bolt 9 and the third mounting hole 15-1 is adjusted to rotate the angle of the first connecting plate 13 relative to the bottom plate 1. After the angle adjustment is completed, the depth of the threaded connection between the L-shaped quick-release bolt 9 and the third mounting hole 15-1 is adjusted to lock the first connecting plate 13 so that it cannot rotate circumferentially along the fourth mounting hole 23-1; preferably, the limit axis 22 is required to be the normal line of the bumper curved surface;

[0045] S3: Place the first automobile bumper 100 (not shown) on the flexible tooling, and the two ends of the first automobile bumper 100 first contact the roller 11. The roller 11 is subjected to the gravity of the first automobile bumper 100 and transmits this force to the first connecting plate 13, so that the nitrogen spring shaft 20 is compressed, and the limit shaft 22 also moves axially therewith, until the entire flexible adaptive mechanism force reaches a balanced state, and the lowest point of the contour of the first automobile bumper 100 just reaches a preset state of contact with the flexible support block 8. At this time, the first automobile bumper 100 is fully supported by the flexible adaptive mechanism 3 and the flexible support block 8 arranged at both ends. At this time, the flexible adaptive mechanism 3 contacts the automobile bumper through the roller, and the relevant assembly tooling is performed;

[0046] S4: When the second automobile bumper needs to be assembled, according to the contour characteristics of the assembled second automobile bumper (not shown), the depth of the threaded connection between the L-shaped quick-release bolt 9 and the third mounting hole 15-1 is adjusted to rotate the angle of the first connecting plate 13 relative to the bottom plate 1. After the angle adjustment is completed, the depth of the threaded connection between the L-shaped quick-release bolt 9 and the third mounting hole 15-1 is adjusted to lock the first connecting plate 13 so that it cannot rotate circumferentially along the fourth mounting hole 23-1;

[0047] S5: Control the reset cylinder 4 so that the cylinder piston rod 4-1 is in an extended state and acts on the fixed disk guide shaft 34. The extension force of the reset cylinder 4 is large enough to make the fixed disk guide shaft 34 move upward along the axial direction with the wire rope. The wire rope will pull the connecting rod 21-4 to drive the pawl 21-6 to rotate counterclockwise around the pawl shaft 21-7 until the pawl tooth 21-6-1 is separated from the ratchet tooth 22-2; under the action of the nitrogen spring shaft 20, the first connecting plate 13 of the limit shaft 22 with the roller 11 moves upward to the highest point; after the reset is completed, the cylinder piston rod 4-1 of the reset cylinder 4 is retracted;

[0048] S6: Repeat the process of assembling the first automobile bumper to install the second automobile bumper.
