[0011] Further, the double-claw hook pin mechanism comprises a first fixed seat fixed on the base plate, a first connecting rod movably arranged in the first fixed seat, and a first handle and a pair of first hook pin blocks rotatably connected to the two ends of the first connecting rod, arc-shaped sliding grooves are arranged on the two first hook pin blocks, the two arc-shaped sliding grooves are oppositely positioned, the ends of the two first hook pin blocks are L-shaped hooks, and the directions of the two L-shaped hooks are opposite.
[0012] The first rotating seat is fixed on the first fixed seat, and the first handle is rotatably connected to the first rotating seat.
[0013] The principle of the double-hook pin mechanism is that two first hook blocks are reversely positioned and coaxially rotate at one end, when the first handle rotates in the first rotating seat, the first connecting rod moves axially and reciprocally relative to the first fixed seat, the first connecting rod drives the two first hook blocks to move reciprocally, because the slide groove angles of the two reversely positioned arc-shaped slide grooves are opposite and are penetrated by the first limiting rod, the two arc-shaped slide grooves form a shears opening and closing movement when reciprocating, and the two L-shaped hooks at the ends of the two first hook blocks are opposite, so when the two L-shaped hooks move away from each other, the two L-shaped hooks are opened to a larger angle and are clamped and abut against the back of the reserved hole of the vehicle body, forming a clamping effect, when the two L-shaped hooks move towards each other, the two L-shaped hooks are overlapped, and at this time, the two L-shaped hooks can freely enter and exit the reserved hole of the vehicle body.

[0016] The second rotating seat is fixed on the second fixed seat, and the second handle is rotatably connected to the second rotating seat.
[0017] The principle of the single-hook pin mechanism is that when the second handle rotates in the second rotating seat, the second connecting rod moves axially and reciprocally relative to the second fixed seat, the second connecting rod drives the second hook block to move reciprocally, because the linear slide groove is penetrated by the second limiting rod, the axis of the linear slide groove and the axis of the second connecting rod form an angle, and the end of the second hook block is an L-shaped hook, so when the second connecting rod drives the second hook block to move away from the working surface, the end of the second hook block moves obliquely, the L-shaped hook is clamped and abut against the back of the reserved hole of the vehicle body, forming a clamping effect, when the second connecting rod drives the second hook block to move towards the working surface, the end of the second hook block returns to the original position, and at this time, the end of the second hook block can freely enter and exit the reserved hole of the vehicle body.

[0020] Further, the maximum width of the ends of the first hook pin block and the second hook pin block is less than 1 / 2 of the diameter of the reserved hole of the vehicle body. Since the end of the hook pin block needs to freely enter and exit the reserved hole of the vehicle body, when the maximum width of the ends of the first hook pin block and the second hook pin block is less than 1 / 2 of the diameter of the reserved hole of the vehicle body, the freedom of entering and exiting can be ensured even if the two hook pin blocks are overlapped and reversely positioned.

[0022] Further, the number of the suction accessories is at least two.
[0023] Further, the first positioning member comprises a first profiling block matched with the profile of the engine cover hinge, and a first positioning pin matched with the reserved hole of the engine cover hinge, and the first positioning pin is a round pin and / or a rhombic pin.
[0024] Further, the second positioning member comprises a second profiling block matched with the profile of the vehicle body, and a second positioning pin matched with the reserved hole of the vehicle body, and the second positioning pin is a round pin and / or a rhombic pin.
[0025] Further, the number of the first positioning pins is at least two.

[0045] Embodiment 1
[0046] As Figures 1-2 shown in the figure, an engine cover hinge positioning tool includes a base plate 1, a first positioning member 2 provided on the base plate 1 for positioning an engine cover hinge 100, and a second positioning member 3 provided on the base plate 1 for positioning a vehicle body 200, and further includes a hook pin assembly provided on the base plate 1 and matched with a reserved hole of the vehicle body 200.
[0047] The working principle of the embodiment is as follows: an operator positions the engine cover hinge 100 on the engine cover hinge positioning tool of the embodiment through the first positioning member 2, moves the engine cover hinge positioning tool to a vehicle body 200 to be installed, positions the engine cover hinge positioning tool with the engine cover hinge 100 on the vehicle body 200 through the second positioning member 3, inserts the end of the hook pin assembly into the reserved hole of the vehicle body 200, and then operates the hook pin assembly to clamp the wall of the reserved hole to achieve fixation. After fixation and clamping, the operator tightens the engine cover hinge 100 on the vehicle body 200 through a manual or electric wrench to complete installation. The engine cover hinge positioning tool of the embodiment is designed in a split type, and a set of symmetrically structured engine cover hinge positioning tools can be used on the left and right sides of the vehicle body 200.
[0048] As Figures 1-2 shown in the figure, the hook pin assembly includes a double-claw hook pin mechanism 41 and a single-claw hook pin mechanism 42 provided on the left and right sides of the base plate 1 respectively.
[0049] As Figure 3 and Figure 4 shown in the figure, the double-claw hook pin mechanism 41 includes a first fixed seat 411 fixed on the base plate 1, a first connecting rod 412 movably provided in the first fixed seat 411, and a first handle 413 and a pair of first hook pin blocks 414 rotatably connected at the two ends of the first connecting rod 412 respectively. Arc-shaped sliding grooves 415 are formed on the two first hook pin blocks 414, the two arc-shaped sliding grooves 415 are oppositely positioned, the ends of the two first hook pin blocks 414 are L-shaped hooks, and the directions of the two L-shaped hooks are opposite.
[0050] The double-claw hook pin mechanism 41 further includes a first limiting rod 416 simultaneously penetrating the two arc-shaped sliding grooves 415, and the first limiting rod 416 is fixed on the first fixed seat 411.
[0051] The double-claw hook pin mechanism 41 further includes a first rotating seat 417 fixed on the first fixed seat 411, and the first handle 413 is rotatably connected to the first rotating seat 417.
[0052] The principle of the double-claw hooking mechanism 41 is that two first hooking blocks 414 are reversely positioned, and one end of the two first hooking blocks 414 rotates coaxially. When the first handle 413 rotates in the first rotating seat 417, the first connecting rod 412 moves axially and reciprocally relative to the first fixed seat 411, and the first connecting rod 412 drives the two first hooking blocks 414 to move reciprocally. Since the slide groove angles of the two reversely positioned arc-shaped slide grooves 415 are opposite, and the two arc-shaped slide grooves 415 are simultaneously limited by the first limiting rod 416, the two arc-shaped slide grooves 415 will form a shears opening and closing movement when reciprocating. Moreover, the two first hooking blocks 414 have L-shaped hooks at the ends, and the directions of the two L-shaped hooks are opposite. Therefore, when the two first hooking blocks 414 move away from each other, the two L-shaped hooks are opened to a larger angle to be clamped and abut against the back of the reserved hole of the vehicle body 200, thereby forming a clamping effect. When the two first hooking blocks 414 move towards each other, the two L-shaped hooks are overlapped with each other, and at this time, the two first hooking blocks 414 can freely enter and exit the reserved hole of the vehicle body 200.
[0053] As shown in Figure 5 The single-claw hooking mechanism 42 includes a second fixed seat 421 fixed on the base plate 1, a second connecting rod 422 movably arranged in the second fixed seat 421, and a second handle 423 and a second hooking block 424 rotatably connected at two ends of the second connecting rod 422, respectively. The second hooking block 424 is provided with a linear slide groove 425, the axis of the linear slide groove 425 and the axis of the second connecting rod 422 form an angle, and the end of the second hooking block 424 is an L-shaped hook.
[0054] The single-claw hooking mechanism 42 further includes a second limiting rod 426 penetrating the linear slide groove 425, and the second limiting rod 426 is fixed on the second fixed seat 421.
[0055] The single-claw hooking mechanism 42 further includes a second rotating seat 427 fixed on the second fixed seat 421, and the second handle 423 is rotatably connected to the second rotating seat 427.
[0056] The principle of the single-claw hooking mechanism 42 is that when the second handle 423 rotates in the second rotating seat 427, the second connecting rod 422 moves axially and reciprocally relative to the second fixed seat 421, and the second connecting rod 422 drives the second hooking block 424 to move reciprocally. Since the linear slide groove 425 is limited by the second limiting rod 426, the axis of the linear slide groove 425 and the axis of the second connecting rod 422 form an angle, and the end of the second hooking block 424 is an L-shaped hook, when the second connecting rod 422 drives the second hooking block 424 to move away from the working surface, the end of the second hooking block 424 will move obliquely, and the L-shaped hook will be clamped and abut against the back of the reserved hole of the vehicle body 200, thereby forming a clamping effect. When the second connecting rod 422 drives the second hooking block 424 to move towards the working surface, the end of the second hooking block 424 returns to the original position, and at this time, the end of the second hooking block 424 can freely enter and exit the reserved hole of the vehicle body 200.
[0057] Such hooking clamping fixing mode only needs to realize the movement mechanism of axial reciprocating motion, and the hooking end is directly fixed with the reserved hole of the vehicle body 200, without the need to set an additional sheet metal imitation block for abutting the traditional pressing device, so the structure is more compact and does not need to occupy a large operation space.
[0058] In this embodiment, the double-claw hooking mechanism 41 and the single-claw hooking mechanism 42 are used in cooperation, one double-claw hooking mechanism 41 can realize the main clamping and fixing function, and the single-claw hooking mechanism 42 can realize the use purpose.
[0059] In this embodiment, the double-claw hooking mechanism 41 and the single-claw hooking mechanism 42 are respectively arranged on the left and right sides of the base plate.
[0060] In this embodiment, the maximum width of the ends of the first hooking block 414 and the second hooking block 424 is less than 1 / 2 of the diameter of the reserved hole of the vehicle body 200. Since the end of the hooking block needs to freely enter and exit the reserved hole of the vehicle body 200, when the maximum width of the end of the hooking block is less than 1 / 2 of the diameter of the reserved hole of the vehicle body 200, even if the two hooking blocks are overlapped and reversely positioned, the freedom of entering and exiting can be ensured.
[0061] The advantage of this embodiment is that the hooking assembly is used for fixing between the tooling and the vehicle body 200, which is different from the traditional flip pressing or opening and closing type clamping and fixing mode. The end of the hooking assembly can be inserted into the reserved hole of the vehicle body 200, the hooking assembly realizes the fixed clamping of the positioning tooling and the vehicle body 200, and then the operator can perform the screw tightening operation. In this embodiment, the hooking assembly is hooked in the reserved hole of the vehicle body 200 to realize hole wall clamping, without the need to adapt the traditional imitation block on the base plate 1 for clamping, so the structure is more compact and effective, and the fixing effect is more effective. Secondly, the hooking assembly does not need to flip space for operation, but reciprocates relative to the axis of the reserved hole of the vehicle body 200, so a large operation space is not needed in use, saving the operation space. The structure of this embodiment is compact, the volume is smaller, the operation occupies a small operation space, and the use is more flexible and convenient.
[0062] Embodiment 2
[0063] This embodiment is similar to embodiment 1, and the difference is that in this embodiment:
[0064] As Figure 2As shown, in this embodiment, the engine hood hinge positioning fixture also includes an adsorption member 5 disposed on the base plate 1. The adsorption member 5 includes a magnet for adsorbing the engine hood hinge 100. Since the adsorption member 5 is a planar adsorption, it does not require additional space, which can ensure the stable positioning of the engine hood hinge 100 on the fixture, and at the same time ensure the positioning accuracy of the engine hood hinge 100. When transferring the fixture to the vehicle body, the risk of the engine hood hinge 100 falling off is not easily detected.
[0065] like Figure 1 As shown, the first positioning component 2 includes a first profile block 21 that mates with the surface of the engine hood hinge 100, and a first positioning pin 22 that mates with the reserved hole of the engine hood hinge 100.

[0068] The number of second contour blocks 31 is not one; they can be adaptively designed according to the specific shape of the exterior of the vehicle body 200 and placed in appropriate positions.
[0069] It should be noted that the round pin is mainly used for positioning and can withstand a certain load, thus playing a role in shear resistance; the diamond pin can prevent axial movement and, during positioning, can prevent torsion during the positioning process in this embodiment, thus improving positioning. The contouring surface of the first contouring block 21 forms the positioning surface between the tooling and the engine hood hinge 100, ensuring the connection stability of the engine hood hinge 100 to the tooling. The contouring surface of the second contouring block 31 forms the positioning surface between the tooling and the vehicle body 200, ensuring the connection stability after the tooling is fixed to the vehicle body 200.
