Description

Technical Field

[0001] The utility model relates to the technical field of positioning tooling, in particular to a positioning tooling for automobile parts. Background Art

[0002] The demand for auto parts is increasing day by day, and auto parts need to be fixed with positioning fixtures during processing. Usually, the positioning fixture is composed of a fixed perforated plate base, a bracket detachably connected to it, and a clamping mechanism set on the bracket; this type of fixture can provide good support for auto parts.

[0003] After the above-mentioned positioning fixtures process the automobile parts, the clamped automobile parts need to be replaced. However, when replacing, the automobile parts usually need to be removed from the positioning fixtures at the processing station before the automobile parts are loaded, clamped and fixed, which results in low overall replacement efficiency and reduced processing efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model adopts the following technical solutions:

[0006] The automobile parts positioning tool comprises two parallel linear displacement mechanisms, each of which is provided with a sliding table, and the sliding table is moved back and forth by the driving of the linear displacement mechanism; the sliding table is provided with a locking and fixing mechanism, and can be detachably connected with the positioning table through the locking and fixing mechanism; the positioning table is provided with a clamping and fixing mechanism for clamping and fixing automobile parts; the tail ends of the two linear displacement mechanisms are provided with a limiting and fixing mechanism for limiting and fixing the positioning table; the limiting and fixing mechanism is provided with a driving displacement mechanism for driving the positioning table to move from the feeding side to the discharging side. Among them, the clamping and fixing mechanism can adopt any one of the existing technologies, as long as it can realize the clamping of the corresponding automobile parts, and it can be selected according to the appearance of the automobile parts and installed on the positioning table. The linear displacement mechanism can adopt any one of the existing technologies, as long as it can realize its technical principle. When in use, the automobile part to be processed is clamped and fixed on the positioning table by the clamping and fixing mechanism, and then the positioning table is detachably connected to the sliding table by the locking and fixing mechanism, and the corresponding mechanism and automobile parts are driven to move to the processing station at the tail end by the linear displacement mechanism, and the positioning table is limited and fixed by the limiting fixing mechanism, and then the locking and fixing mechanism on the linear displacement mechanism on the feeding side is unlocked, so that the positioning table is fixed on the limiting fixing mechanism, and the sliding table is reset to the head end of the linear displacement mechanism on the feeding side, so that when the previous automobile part is processed, the next positioning table driving the automobile part can be detachably connected; when the previous automobile part is processed, it is driven by the driving displacement mechanism to move it to the sliding table on the linear displacement mechanism on the discharging side, and it is detachably connected by the locking and fixing mechanism on the sliding table, and then the limiting fixing mechanism is unlocked, so that the corresponding mechanism and automobile parts can be driven to their head end by the linear displacement mechanism on the discharging side, and the positioning table with the automobile parts is removed. The structure of the present application is adopted, and two parallel linear displacement mechanisms are provided and divided into a feeding side and a discharging side, so that the positioning table with the automobile parts fixed by the clamping and fixing mechanism is moved from the head end of the linear displacement mechanism on the feeding side to the processing station at the tail end for processing with the corresponding parts, and then the positioning table is moved to the linear displacement mechanism on the discharging side by the driving displacement mechanism, and is driven by it to move from the tail end to the head end, and the sliding table and positioning table are detachably connected in a manner that the positioning table can be conveniently disassembled and assembled, so that the next automobile part can be fixed on the sliding table through the positioning table while the previous automobile part is being processed, so as to realize preparation, shorten the replacement time and improve the production efficiency; at the same time, the positioning table can be detachably connected to the sliding table by the locking and fixing mechanism, and the positioning table can be limited and fixed by the limiting fixing mechanism, so that the driving displacement mechanism is used to drive the automobile parts and the positioning table to move from the feeding side to the sliding table on the discharging side, so as to carry out unloading.

[0007] Furthermore, the locking and fixing mechanism includes a lifting guide rod, a lifting screw rod, a connecting plate and a first motor; the first motor is arranged on the connecting plate, the lower end of the lifting screw rod is fixedly connected to the output end of the first motor, and the lower end of the lifting guide rod is fixedly connected to the connecting plate; the sliding platform is provided with a first lifting threaded through hole matching the lifting screw rod and a first lifting guide through hole matching the lifting guide rod, and the positioning platform is provided with a second lifting threaded through hole matching the lifting screw rod and a second lifting guide through hole matching the lifting guide rod. When in use, the lifting screw rod is driven to rotate by the first motor, so that under the limit of the lifting guide rod, the lifting screw rod can move from the first lifting threaded through hole to the second lifting threaded through hole, thereby realizing the connection and fixation between the positioning platform and the sliding platform; otherwise, the connection and fixation between the contact positioning platform and the sliding platform is realized, so that the sliding platform can be reset and connected and fixed with the next positioning platform.

[0008] Further, the position-limiting fixing mechanism comprises a linear slide rail with a moving direction perpendicular to the linear displacement mechanism, a slide seat is provided on the linear slide rail, a displacement platform is provided on the slide seat, the displacement platform is displaced by the drive of the slide seat, a symmetrically arranged transverse guide rod is provided on the displacement platform, a transverse plate is slidably connected to the transverse guide rod, a second motor is provided on the transverse plate, a transverse screw is provided at the output end of the second motor, an elastic member is provided between the transverse plate and the displacement platform, and an anti-slip member matching the displacement platform is provided on the transverse plate; a first transverse threaded through hole matching the transverse screw and a first transverse guide through hole matching the transverse guide rod are provided on the positioning platform; a positioning block is provided on the transverse guide rod. The elastic member can be a spring. When in use, when the sliding table and the positioning table move to the displacement table, the transverse guide rod is directly inserted into the first transverse guide through hole and reaches the positioning block on the transverse guide rod for positioning. At this time, the transverse screw has not rotated into the first transverse threaded through hole and is pressed by the positioning table to cooperate with the transverse plate to move on the transverse guide rod and compress the elastic member, and then the transverse screw is driven to rotate by the second motor, so that under the thrust provided by the elastic member outward, the end of the transverse screw can press against the first transverse threaded through hole to achieve preliminary connection, and then rotate in the first transverse threaded through hole. The threaded through hole is displaced, and the position of the positioning table on the displacement table is fixed. After the locking and fixing mechanism is released, the sliding table on the feed side can be moved and reset. After the processing is completed, the sliding mechanism is driven to move on the linear slide rail, moving from the feed side to the discharge side, and the locking and fixing mechanism on the sliding table on the discharge side is used to connect and fix the sliding table. Then the second motor is reversed to make the transverse screw disengage from the first transverse threaded through hole, so that the sliding table on the discharge side can cooperate with the corresponding linear displacement mechanism to drive the positioning table to move. The positioning block can realize the positioning of the positioning table and ensure the accuracy of the processing; the anti-slip component can prevent the transverse plate from disengaging from the transverse guide rod.

[0009] Furthermore, the driving displacement mechanism includes a cylinder seat arranged outside any of the linear displacement mechanisms, the cylinder seat is provided with a linear cylinder, and the output end of the linear cylinder is fixedly connected to the slide seat. With this structure, the slide seat can be driven to move on the linear slide rail by the linear cylinder.

[0010] Furthermore, the anti-dropping member is an L-shaped plate, and one side of the L-shaped plate cooperates with the displacement table to limit and prevent drop-off. With this structure, the displacement table can be hooked by one side of the L-shaped plate to prevent drop-off.
