Description

Technical Field

[0001] This utility model relates to the field of flipping fixtures for flipping mechanisms, and in particular to a flipping fixture for a torsion bar flipping mechanism assembly. Background Technology

[0002] The torsion bar flipping mechanism uses several torsion bars in conjunction with a rotating shaft and a locking mechanism to move the moving parts in the overall structure. During this process, the end of the flipping mechanism will clamp the workpiece to be processed through a fixture.

[0003] To ensure that the workpiece can achieve more flipping angles, the connecting fixture bracket is usually connected to the motor so that the connecting fixture can rotate. The workpiece itself has a certain weight and generates a certain amount of kinetic potential energy during the movement of the workpiece. After the flipping is completed, the kinetic potential energy will cause the connecting rod between the connecting fixture bracket and the motor to twist. This twisting will cause certain damage to the connecting rod and affect the accuracy of the movement of the fixture during the flipping process. Long-term use will cause errors in the movement of the fixture. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a flipping fixture for a torsion bar flipping mechanism assembly, which solves the problem that the connecting rod that drives the fixture to rotate is damaged under torque during the flipping process of the fixture, resulting in errors.

[0005] The technical solution of this utility model is as follows: a flipping fixture for a torsion bar flipping mechanism assembly, comprising two worm gears arranged side by side with opposite tooth grooves, a surrounding plate bracket provided on the outside of the worm gears, a rotating rod coaxially provided on the two worm gears, the rotating rod passing through the surrounding plate bracket and fixedly connected to the fixture bracket, two parallel worms meshing at the bottom of the two worm gears, the two worms rotating in opposite directions, support plates connected to the surrounding plate bracket provided on both sides of the worms, a driven gear provided on the same side of the two worms, a driving gear meshing between the driven gears of the two worms, a coupling provided at the end of the driving gear, and a motor provided at the other end of the coupling.

[0006] Furthermore, a rotating shaft is provided between the worm and the support plate, and a driven gear is provided on the same side of the two worms passing through the support plate to ensure the stable installation of the worms.

[0007] Furthermore, the support plate is provided with a positioning gear that meshes with the driving gear on the side near the driven gear. There are two positioning gears in total, which are respectively located at the top and bottom of the support plate. The left and right sides of the driving gear mesh with the driven gear, and the top and bottom sides mesh with the positioning gear, thus restricting the position of the driving gear. The two positioning gears and the two driven gears form a cross-shaped structure to restrict the driving gear to the center position, thereby ensuring effective meshing between the driving gear and the driven gear.

[0008] Furthermore, a damper is provided on the surface of the support plate, and the positioning gear is connected to the support plate through the damper. The damper limits the maximum speed of the driving gear by the positioning gear, so as to prevent the driving gear from rotating too fast.

[0009] Furthermore, a limiting frame connected to the support plate is provided on the outside of the driving gear. The limiting frame consists of several horizontal support rods and a vertical plate at the end of the support rods. The driving gear extends outward through the vertical plate. A rotating shaft is keyed between the driving gear and the limiting frame. The limiting frame fixes the position of the driving gear and covers the meshing area of ​​the driving gear and the driven gear for protection.

[0010] Furthermore, a key connection is provided between the rotating rod and the worm gear to ensure a stable connection.

[0011] Furthermore, the coupling is a telescopic coupling assembly, with the end where the motor is located being a fixed end and the end of the coupling connected to the drive gear being a movable end. The motor can be placed outside the overall reversing mechanism. The telescopic coupling ensures that effective output can be maintained when the reversing mechanism is reversed to any angle.

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

[0013] 1. This utility model uses a worm gear to drive a worm wheel to rotate, and the rotating worm wheel can drive a rotating rod to rotate. The clamp bracket is set at the end of the rotating rod, which shortens the length of the rod that provides the rotation of the clamp bracket, reduces the influence of torque on the rotating rod, and the worm gear transmission is more precise than the method of directly connecting the motor to the rotating rod. The shorter rotating rod itself is less expensive than the long connecting rod, and can be directly replaced if it breaks.

[0014] 2. This utility model connects the motor and the worm gear through a retractable coupling, ensuring that the motor can provide power to the worm gear. The motor is set independently outside the overall structure and does not affect the normal transmission of the motor. This eliminates the need for the reversing mechanism to bear the weight of the motor, reducing the burden on the reversing mechanism during operation. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figure 1-3 As shown, a flipping fixture for a torsion bar flipping mechanism assembly includes two worm gears 1 arranged side by side with opposite tooth grooves. A surrounding plate bracket 2 is provided on the outside of the worm gears 1. A rotating rod 3 is coaxially arranged on the two worm gears 1. A key connection is provided between the rotating rod 3 and the worm gears 1 to ensure a stable connection. The rotating rod 3 passes through the surrounding plate bracket 2 and is fixedly connected to the fixture bracket 4. Two parallel worms 5 are meshed at the bottom of the two worm gears 1. The rotation directions of the two worms 5 are opposite. Support plates 6 connected to the surrounding plate bracket 2 are provided on both sides of the worms 5.

[0021] Driven gears 7 are provided on the same side of the two worm gears 5. A rotating shaft is provided between the worm gears 5 and the support plate 6. Driven gears 7 are provided through the support plate 6 on the same side of the two worm gears 5 to ensure the stable installation of the worm gears 5. A driving gear 8 is meshed between the driven gears 7 of the two worm gears 5. A positioning gear that meshes with the driving gear 8 is provided on the side of the support plate 6 near the driven gear 7. There are two positioning gears. The two positioning gears are respectively provided on the top and bottom of the support plate 6. The left and right sides of the driving gear 8 mesh with the driven gears 7 respectively, and the top and bottom sides mesh with the positioning gears respectively, restricting the position of the driving gear 8. The two positioning gears and the two driven gears 7 form a cross-shaped structure to restrict the driving gear 8 to the center position to ensure effective meshing between the driving gear 8 and the driven gear 7. A damper is provided on the surface of the support plate 6. The positioning gear is connected to the support plate 6 through the damper. The damper restricts the maximum speed of the driving gear 8 to prevent the driving gear 8 from rotating too fast.

[0022] A limiting frame connected to the support plate 6 is provided on the outside of the driving gear 8. The limiting frame consists of several horizontal support rods and a vertical plate at the end of the support rods. The driving gear 8 extends outward through the vertical plate. A rotating shaft is keyed between the driving gear 8 and the limiting frame. The limiting frame fixes the position of the driving gear 8 and covers the meshing area between the driving gear 8 and the driven gear 7 for protection. A coupling 9 is provided at the end of the driving gear 8. A motor is provided at the other end of the coupling 9. The coupling 9 is a telescopic coupling assembly. The end with the motor is the fixed end, and the end of the coupling 9 connected to the driving gear 8 is the movable end. The motor can be placed outside the overall reversing mechanism. The telescopic coupling 9 can ensure that effective output is maintained when the reversing mechanism is reversed to any angle.

[0023] The working principle of this utility model is as follows: First, during use, the torsion bar flipping mechanism flips to the required angle. During this process, the coupling 9 is open or closed to maintain the connection between the motor and the drive gear 8. After the torsion bar flipping mechanism moves to the required position, the motor starts and drives the coupling 9 to rotate. At the same time, the driven gear 7 meshing with the drive gear 8 rotates. When the driven gear 7 rotates, it drives the worm 5 to rotate relative to each other. The two worms 5 rotating relative to each other drive the worm wheel 1 to rotate in the same direction, thereby causing the rotating rod 3 inside the worm wheel 1 to rotate. Even if the workpiece held by the clamp on the surface of the clamp bracket 4 reacts and affects the rotating rod 3, it is difficult for it to directly act on the worm wheel 1 and the worm 5.

[0024] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
