Referring to fig. 1 to 3, the present application provides a hinge mounting fixture 1, which is suitable for delivering a hinge to a mounting surface of an object, and the following embodiment uses the object as a door of an automobile, and the mounting surface is a side surface of the door provided with a lock hole as an example, but not limited thereto. The hinge mounting fixture 1 includes a work platform 10, a delivery assembly 20, and a drive assembly 30. The working platform 10 comprises a storage area and an assembly area, wherein a plurality of bearing frames are arranged on the storage area at intervals for placing the vehicle door in the storage area, so that the vehicle door is supported from the working platform

A predetermined distance allows the locking position (or keyhole) on the door to be at the same level 5 as the object to be mounted (e.g., hinge). The assembly area is provided with linear rails 11, the linear rails 11 may be, but are not limited to, one or more

The plurality of sliding rails 111 are disposed in the assembly area, and two sliding rails 111 are disposed at intervals in the present embodiment for illustration, but not limited thereto, wherein the two sliding rails 111 are disposed in parallel and extend along the assembly area toward the storage area.

The delivery component 20 is movably arranged on the linear rail 11 and can move 0 towards the direction of the object placing area to be close to the mounting surface of the vehicle door, or move in the opposite direction to be far away from the mounting surface and return to be positioned on the assembly

The starting position of the zone. The delivery assembly 20 comprises a base 21 and a clamp 22, wherein the base 21 comprises a carrier plate 211 and a chute 212. The sliding groove 212 is disposed on the bottom surface of the carrier 211, so that the carrier 211 can be correspondingly sleeved on the linear rail 11 through the sliding groove 212, and movably disposed on the linear rail 11 and can be linearly displaced relative to the working platform 10. Therefore, the number of the sliding grooves 212 on the bottom surface of the carrier 211 is matched with the number of the linear rails 11 by 5, for example, two sliding grooves 212 are symmetrically arranged on the bottom surface of the carrier 211 and are sleeved on the two corresponding linear rails 11 on the working platform 10, so as to provide stability when the carrier 211 moves.

The clamp 22 of the delivery assembly 20 is disposed on the carrier 211 of the base 21, and the clamp 22 includes a body 221 and a cantilever 222. The body 221 is disposed on the top surface of the carrier 211. Cantilever 222 includes a fixed end and a free end

The fixed end is connected to the body 221, and the free end is bent relative to the fixed end and extends toward the first direction D1 to suspend 0 above the base 21 or the working platform 10. Wherein the free end is provided with a positioning portion 2220 at the end thereof for

To carry the hinge. The positioning portion 2220 has an abutment surface 2221 on a side facing the storage area, which corresponds to the mounting surface of the vehicle door and intersects with the extending direction of the linear rail 11, for example, the extending direction of the linear rail 11 is perpendicular to the abutment surface 2221, so that the hinge can be guided by the abutment surface to abut against the positioning portion 2220 at a correct mounting angle.

The 5-drive assembly 30 is disposed on the work platform 10 and interposed between the storage area and the delivery assembly 20.

The drive assembly 30 includes a power source 31 and a buffer 32. The power source 31 is connected to the delivery assembly 20, and is used for driving the delivery assembly 20 to move on the linear rail 11, so that the delivery assembly 20 is moved towards the placement area along the first direction D1 to be close to the mounting surface of the vehicle door, or is moved towards the assembly area along the second direction D2 from the placement area to be far away from the mounting surface of the vehicle door, and returns to the initial position. Thus, the power source 31 may be, but is not limited to, a pneumatic cylinder including a telescopic rod 311, and the telescopic rod 311 is pneumatically driven to extend toward the second direction D2 or retract toward the first direction D1, wherein one end of the telescopic rod 311 is connected to the carrier plate 211 of the base 21 between the two linear rails 11, so as to drive the base 21 to stably displace toward the first direction D1 and the second direction D2, so that the cantilever 222 may deliver the hinge toward the mounting surface of the vehicle door and further away from the mounting surface after the hinge is tightened.

The damper 32 of the driving assembly 30 is provided at one side of the power source 31 and corresponds to the linear rail 11 or the clamp 22. The damper 32 may be, but is not limited to, a spring damper or a hydraulic damper coupled to the delivery assembly 20 to apply a reverse force to the delivery assembly 20, i.e., a resistance force toward the second direction D2, when the delivery assembly 20 is displaced toward the first direction D1 to compress the damper 32, and adjust a gap between the hinge and the mounting surface by the resistance force so that the hinge may be as close to the mounting surface as possible and avoid collision with each other. In some embodiments of the present application, the buffer 32 may also be disposed on a moving path of the delivery assembly 20 toward the storage area, and spaced apart from the delivery assembly 20 by a predetermined distance without being connected to the delivery assembly 20. Thus, delivery assembly 20 is initially in contact with bumper 32 after being displaced a predetermined distance in first direction D1. Thereafter, as delivery assembly 20 continues to be displaced in first direction D1, bumper 32 creates a resistive force on delivery assembly 20 in second direction D2, thereby acting to adjust the size of the gap therebetween.

It will be appreciated that in the general design of a vehicle door, a hinge is typically mounted on each of the upper and lower sides of the mounting surface to allow smooth pivoting of the door to open or close. Therefore, in the embodiment of the present application, the number of the clips 22 of the delivery assembly 20 may be matched with the number of the locking positions on the mounting surface, that is, two clips 22 are provided, and the two clips 22 may be disposed on the carrier 211 of the base 21 at intervals according to the mounting positions of the hinge. Meanwhile, the number of buffers 32 is matched with the number of jigs 22 (two in each case) to adjust or synchronize the gap between the jigs 22 and the mounting surface. In configuration, the buffers 32 are fixed on the working platform 10 through the fixing blocks 321, the setting positions of the two buffers 32 are in one-to-one correspondence with the setting positions of the clamps 22, and the power source 31 is arranged between the two buffers 32, so that the power source is connected between the two clamps 22 on the carrier plate 211 of the base 21. By this arrangement, when the hinges are carried by the cantilevers 222 of the jigs 22, the hinges on the different jigs 22 are provided with the same axiality, so that the problem of position deviation possibly occurring between the hinges carried by the different jigs 22 before assembly is eliminated, and by the action of the buffer 32, the gap between the jigs 22 and the mounting surface can be made uniform when the hinges are forced to be close to the mounting surface, or the gap between the different gaps can be reduced as much as possible.

Furthermore, in other embodiments of the present application, the hinge mounting fixture 1 further includes a linker 40, and a coupling portion 213 is further disposed on the base 21 of the delivery assembly 20, wherein the coupling portion 213 is disposed on the carrier 211 and between the two jigs 22. The linker 40 is detachably connected between the telescopic rod 311 of the power source 31 and the combining part 213 of the base 21, so that the power source 31 can drive the base 21 to move via the linker 40, and the hinge mounting fixture 1 is convenient to mount, dismount and maintain. The first concave-convex structure is disposed between the linker 40 and the coupling portion 213, for example, a bump 41A, for example, a T-shaped bump, is disposed on a side of the linker 40 facing the coupling portion 213, and a corresponding groove 213A is disposed on a side of the coupling portion 213 facing the linker 40, so that the coupling portion 213 and the linker 40 are engaged with each other by the T-shaped concave-convex structure.

Similarly, a mating second relief structure is provided between the linker 40 and the telescoping rod 311. The head end of the telescopic rod 311 is provided with a protruding part, and one side of the linker 40 facing the telescopic rod 311 is provided with a matched recessed part, so that the telescopic rod 311 and the linker 40 are mutually clamped and connected, and the linker 40 is used as a transmission path of force to drive the delivery assembly 20 to move on the working platform 10. Of course, the connection method is not limited to the concave-convex matching structure, and in other possible embodiments, the connection purpose can be achieved by means of clamping, buckling or screwing.

The embodiment of the application is suitable for an application scene of installing the hinge on the vehicle door. The door is placed in the storage area of the work platform 10 such that the locking mechanism of the door is supported in a predetermined horizontal position. And two hinges are provided at the positioning portions 2220 on the cantilevers 222 of the two jigs 22, respectively. Then, the power source 31 of the driving unit 30 drives the telescopic rod 311 to pull the base 21 of the delivery unit 20, thereby applying a force to the delivery unit 20 for displacing in the first direction D1. When the clamp is brought close to the mounting surface of the door and the hinge is brought into contact with the mounting surface of the door and gradually and completely fitted, the mounting surface of the door generates a reaction force in the second direction D2, i.e., a reaction force of the above-mentioned force, to the delivery assembly 20. At the same time, two bumpers 32 also create a resistance to the delivery assembly 20 in the second direction D2. At this time, the force applied by the power source 31 in the first direction D1 can be controlled to approach the sum of the reaction force and the resistance force in the second direction D2, so that the force balance can be achieved. Because the force applied during balancing is small, the gap between the clamp 22 and the mounting surface due to slight deviation can be eliminated, so that the locking surface of the hinge and the mounting surface of the vehicle door are attached as much as possible, and the reaction force or vibration generated during locking of an electric fixing tool (such as an electric gun) can be resisted, so that residual stress formed in the vehicle door due to deviation generated in the fixing process of the hinge can be avoided.

It should be noted that, since the abutment surface 2221 of the positioning portion 2220 provided on the cantilever of the fixture is perpendicular to the extending direction of the linear rail 11 and corresponds to the mounting surface of the vehicle door, the locking surface of the hinge is maintained as parallel as possible to the mounting surface of the vehicle door when the hinge is close to the vehicle door, so that the rotation axes of the two hinges are maintained in a coaxial line (i.e. not eccentric state), but the mounting surface of the hinge or the vehicle door may still have slight deviation due to the parts, so that the gap generated due to the slight deviation is eliminated by the design of the two buffers 32, the force caused during locking can be resisted, the deformation of the vehicle door due to the deviation of the parts is avoided, and the problems that the conventional fixture is easy to generate internal stress or lower in assembly qualification rate due to the deviation of the parts are solved.

From the above description, the present application can stably move on the linear track of the working platform through the delivery assembly, and the auxiliary adjustment of the buffers at both sides of the power source can be matched, so that the manufacturing deviation of the vehicle door and the hinge due to parts can be effectively eliminated, and the unpredictable deformation and residual stress caused by tightening the bolts can be avoided, thereby improving the stability of the assembly dimension. Meanwhile, in the delivering process of the hinge, the locking surface of the hinge and the mounting surface of the vehicle door can be kept to be attached as far as possible, so that the hinge can be accurately mounted on the mounting surface of the vehicle door, and the stability of the coaxiality of the upper hinge and the lower hinge of the vehicle door and the success rate of assembly of the vehicle door are improved.

In addition, it should be noted that when the assembly vehicle door is in a problem, unexpected deformation is easily generated between the hinge and the mounting surface of the vehicle door due to mounting deviation, so that problem analysis is relatively complex and difficult.

The foregoing is merely exemplary of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc. which are within the spirit and principles of the present application are intended to be included within the scope of the claims of the present application.
