Description

Technical Field

[0001] This application belongs to the technical field of mechanical automation, and particularly relates to a spring piece assembly positioning fixture. Background Art

[0002] In mechanical automation processing, fixtures are often used to hold products to facilitate assembly, welding, riveting and other processes.

[0003] When processing connectors, there are assemblies of particularly precise small components such as spring pieces and moving contact pieces inside the connectors, and after being assembled, they are assembled onto the base. Traditional assembly is manual assembly. Due to the low efficiency of manual assembly, automated assembly has emerged. Automated assembly poses new requirements for the fixtures that hold products. Since spring pieces and moving contact pieces are precise small components and the installation actions are also relatively special, including assembly and pressing down and other actions, special fixtures are required for fixation to facilitate the assembly process. Therefore, a new technology is proposed. Content of the Utility Model

[0004] The technical problem to be solved by the present utility model is: to solve the deficiency that the existing fixtures cannot provide stable clamping support for spring pieces and moving contact pieces, and thus provide a spring piece assembly positioning fixture.

[0005] The technical solution adopted by the present utility model to solve its technical problems is:

[0006] A spring piece assembly positioning fixture includes a fixed seat, a clamping component, a pressing component, a central upper support component, and an upper cover. The product is placed on the central upper support component. The clamping component is located on the fixed seat to clamp the product on the central upper support component. The pressing component presses the top of the product clamped by the clamping component. The upper cover fixes the clamping component on the fixed seat to achieve the clamping action.

[0007] Further, the clamping component includes a left clamping component and a right clamping component. The left clamping component and the right clamping component are symmetrically arranged with the central upper support component as the center, and cooperate with each other to clamp the product. Both the left clamping component and the right clamping component include chutes opened at both sides on the fixed seat, push rods, push rod springs, fixed clips, and moving clips. The push rods slide in the chutes. Part of the push rods is located outside the fixed seat. The part of the push rods located outside the fixed seat is sleeved with push rod springs. One end of each push rod spring is fixed to the push rod and the fixed seat respectively. The moving clips are fixed on the fixed seat, and the moving clips are respectively fixed on the push rods. The fixed clips and the moving clips are symmetrically arranged with the central upper support component as the center.

[0008] Further, the pressing component includes a movable slot, a pulling slot, a pull rod, a pressing body, a connecting arm, and a pressing block. The movable slot is opened on the fixed seat and located on the central axis of the central upper supporting component. The pulling slot extends to the central upper supporting component and is opened along the central axis of the central upper supporting component. The pulling slot communicates with the movable slot. The pull rod slides in the pulling slot, and a part of the pull rod is located outside the fixed seat. The pull rod is rotatably connected to the pressing body through a pin shaft at the movable slot. The pressing body is provided with a downward-inclined braking surface near the central upper supporting component. The connecting arm is connected to the upper surface of the pressing body, and the other end of the connecting arm is connected to the pressing block. Pressing the pressing body downward drives the pressing block to press the product downward.

[0009] Further, one end of the push rod located outside the fixed seat is provided with a push handle, and the push rod spring is embedded in the push handle.

[0010] Further, one end of the pull rod located outside the fixed seat is provided with a handle.

[0011] Further, the virtual line graph formed by connecting the pressing body, the connecting arm, and the pressing block end to end is an isosceles trapezoid.

[0012] The beneficial effects of the present utility model are as follows:

[0013] When the product of the present utility model is used in cooperation with automated instruments, the spring force of the push rod spring ensures that the left clamping component and the right clamping component are in an open state. When the lower spring sheet is placed on the central upper supporting component, the push rod is pushed by an external linear driving component, driving the left clamping component and the right clamping component to clamp around the lower spring sheet. This facilitates the installation of the moving contact piece on the lower spring sheet. Then, after the upper spring sheet is installed at the corresponding positions of the lower spring sheet and the moving contact piece, the pressing component presses the assembly to complete the assembly. In summary, the product of the present utility model can achieve assembly actions such as clamping and pressing according to the assembly sequence, cooperate with automated equipment, and improve the assembly efficiency.

[0026] The clamping component 20 includes a left clamping component 21 and a right clamping component 22. The left clamping component 21 and the right clamping component 22 are symmetrically arranged with the central upper support component 40 as the center axis and cooperate to clamp the product. The left clamping component 21 or the right clamping component 22 includes sliding grooves 211 opened on both sides of the fixed seat 10, a push rod 212, a push rod spring 213, a fixed clamping piece 214, and a movable clamping piece 215. The push rod 212 slides in the sliding groove 211. Part of the push rod 212 is located outside the fixed seat 10. The part of the push rod 212 located outside the fixed seat 10 is sleeved with the push rod spring 213. One end of the push rod spring 213 is fixed to the push rod 212 and the fixed seat 10 respectively. The movable clamping piece 215 is fixed on the fixed seat 10. The movable clamping piece 215 is respectively fixed on the push rod 212. The fixed clamping piece 214 and the movable clamping piece 215 are symmetrically arranged with the central upper support component 40 as the center axis; a push handle 216 is provided at one end of the push rod 212 located outside the fixed seat 10, and the push rod spring 213 is embedded in the push handle 216.

[0027] The pressing component 30 includes a movable groove 31, a pulling groove 32, a pull rod 33, a lower pressing body 34, a connecting arm 35, and a pressing block 36 opened on the upper surface of the fixed seat 10 and located on the central axis of the central upper support component 40. The movable groove 31 extends to the central upper support component 40. The pulling groove 32 is opened along the central axis of the central upper support component 40. The pulling groove 32 communicates with the movable groove 31. The pull rod 33 slides in the pulling groove 32. Part of the pull rod 33 is located outside the fixed seat 10. The pull rod 33 is rotatably connected to the lower pressing body 34 through a pin shaft at the movable groove 31. The lower pressing body 34 is provided with a downwardly inclined braking surface 38 near the central upper support component 40. A connecting arm 35 is connected to the upper surface of the lower pressing body 34. The other end of the connecting arm 35 is connected to the pressing block 36. Pressing the braking surface 38 of the lower pressing body 34 downward drives the pressing block 36 to press the product downward; a handle 37 is provided at one end of the pull rod 33 located outside the fixed seat 10; the virtual line graph formed by connecting the lower pressing body 34, the connecting arm 35, and the pressing block 36 end to end is an isosceles trapezoid.

[0028] The upper cover 50 does not interfere with the actions of the clamping component 20 and the pressing component 30, but protects the clamping component 20 on the fixed seat 10.

[0029] When the product of the present utility model is in use:

[0030] Due to the elastic force of the push rod spring, the movable clamping piece moves away from the fixed clamping piece. At this time, the gap between the left clamping component and the right clamping component facilitates the manipulator to place the spring piece on the central upper supporting component in the middle. Then, an external driving component presses the push rod, driving the movable clamping piece to approach the fixed clamping piece. The left clamping component and the right clamping component clamp the spring piece. Then the manipulator can connect the movable contact piece to the lower spring piece according to the installation sequence. Then the manipulator installs the upper spring piece on the part between the lower spring piece and the movable contact piece. The driving component then pushes the pull rod, and the pull rod drives the lower pressing body to move towards the central upper supporting component. When the braking surface contacts the central upper supporting component, under the action of the lever, the pressing block at the other end is driven to press down on the top surface of the lower spring piece, realizing the buckling action of components such as the spring piece and the movable contact piece. Then, after the structure of the product of the present utility model is restored, the manipulator can take away the assembled product.
