Description

Technical Field

[0001] This utility model relates to the field of halogen lamp processing technology, and in particular to a deformation-resistant positioning tooling for processing filaments of automotive halogen lamps. Background Technology

[0002] The anti-deformation positioning fixture for automotive halogen lamp filaments is a positioning tool used in the production of automotive halogen lamps to prevent filament deformation during processing. After being cut and bent, the molybdenum wire is fixed to the lamp holder and then bridged with an aluminum sheet to connect the filament. During the bridging process, the molybdenum wire with the lamp holder is first placed in the groove of a support block, with the wire extending beyond the block. A pressure rod is then used to press the lamp holder firmly to prevent deformation during welding. Subsequently, a pressure welding device welds the extended molybdenum wire onto the aluminum sheet.

[0003] After the robotic arm places the lamp holder and molybdenum wire in the groove, the turntable will drive the support block to rotate and rotate it to the welding position. Because there is still a certain gap in the groove, the lamp holder will wobble during rotation, causing a slight deviation when the molybdenum wire is welded to the aluminum sheet, which affects the performance of the filament. Therefore, it is necessary to provide a deformation-resistant positioning fixture for processing filaments for automotive halogen lamps to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a deformation-resistant positioning fixture for processing filaments of automotive halogen lamps, in order to solve the problem mentioned in the background art, where after the robot arm places the lamp holder and molybdenum wire in the groove, the turntable will drive the support block to rotate and rotate it to the welding position. Because there is still a certain gap in the groove, the lamp holder will wobble during rotation, resulting in a slight deviation when welding the molybdenum wire and the aluminum sheet, which affects the performance of the filament.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model relates to an anti-deformation positioning fixture for processing filaments in automotive halogen lamps, comprising:

[0007] The positioning component includes a turntable, a support base, a support block, a groove, and a pressure rod. The support base is fixed to the side of the turntable and is symmetrically distributed. The support block is fixed to the side of the support base. The groove is formed on the support block. The pressure rod is movably connected to the upper end of the turntable.

[0008] The pushing assembly includes a support rod, a shaped block, and a guide block. The support rod is fixed inside the pressure rod and near its lowest end, the shaped block is fixed at the lower end of the support rod, and the guide block is fixed inside the groove and near one end.

[0009] Furthermore, the pushing assembly also includes a waist hole and a bolt. The waist hole is opened at one end of the pressure rod, and the lower end of the bolt is fixed to the support rod and inserted into the waist hole, and is tightened by a nut.

[0010] Furthermore, the pushing component also includes a first rubber pad, which is fixed to the side of the irregular block.

[0011] Furthermore, the irregular block is trapezoidal, with rounded corners at the bends of the inclined surface, and the first rubber pad is fixed to the inclined surface.

[0012] Furthermore, the positioning component also includes a device base, a rotating base, and an electric push rod. The lower end of the rotating base is rotatably connected to the upper end of the device base, and the upper end of the rotating base is fixed to the lower end of the turntable. The electric push rod passes through the turntable and the rotating base and is fixed on the device base.

[0013] Furthermore, it also includes a damage prevention component, which includes a first support plate, a threaded hole, a threaded rod, and a second support plate. The first support plate is fixed at one end below the support block, the threaded hole is opened in the middle of one end of the first support plate, the threaded rod is screwed into the threaded hole, and its upper end is rotatably connected to the middle of the lower end of the second support plate.

[0014] Furthermore, the damage prevention component also includes limiting holes and limiting rods. The limiting holes are formed at both ends of the first support plate, and the limiting rods are inserted into the limiting holes, with their upper ends fixed to the lower end of the second support plate.

[0015] Furthermore, the damage prevention component also includes a second rubber pad, which is fixed to the upper end of the second support plate.

[0016] Compared with existing technologies, the advantages of this utility model are:

[0017] I. This utility model, through the set push component, allows the robot to place the lamp holder in the groove. The lamp holder slides along the guide block and moves to the center of the groove. Then, the turntable drives the support block to rotate to the welding position. The electric push rod retracts, driving the pressure rod to move downward. The irregular block at the lower end of the support rod moves downward accordingly. The lower end of the first rubber pad contacts the side of the lamp holder. As the irregular block moves downward, it drives the lamp holder to move towards the end of the groove away from the support seat until it moves to the inner side of the groove. At this time, the pressure rod presses on the lamp holder, and the welding operation can begin. This setting can move the lamp holder to the optimal position, so that the welding position of the molybdenum wire and the aluminum sheet is optimal.

[0018] II. In this utility model, by setting the anti-damage component, the threaded rod in the threaded hole is rotated to drive the second support plate to move, and at the same time, the limiting rod is driven to move along the limiting hole to move the second rubber pad to the appropriate position. The robot arm places the lamp holder in the groove. At this time, the protruding molybdenum wire is close to the support block and fits with the second rubber pad. This setting can avoid the downward force during welding of the molybdenum wire, which would cause the connection between the molybdenum wire and the lamp holder to bend and be damaged.
