[0004] The technical problem to be solved by this utility model is to provide a clamping device for processing medical device parts, which can facilitate the uniform clamping of thin-walled circular parts, avoid damage to them, and facilitate subsequent processing.

[0005] This utility model achieves its purpose through the following technical solution:

[0006] A clamping device for processing medical device parts is characterized by comprising: a clamping base, wherein a set of limiting rods are fixedly connected to the clamping base, and each limiting rod is fixedly connected to a center plate; a set of transmission gears, wherein the central shaft of each transmission gear is bearing-connected to the center plate, and the central shaft of each transmission gear is fixedly connected to a swing arm; and a set of symmetrical mounting plates, the central shafts of which are bearing-connected to the corresponding swing arms, and clamping posts are fixedly connected to the eccentric portion of each mounting plate. By employing clamping posts evenly distributed along the circumferential direction, uniform clamping of thin-walled ring parts can be easily achieved, avoiding damage to them.

[0007] As a further limitation of this technical solution, an external gear is fixedly connected to the central shaft of each of the outer mounting discs, and an internal gear is fixedly connected to the central shaft of each of the inner mounting discs. Each external gear meshes with a corresponding internal gear. By using external and internal gears, their meshing achieves reverse rotation, causing the inner and outer clamping columns to swing in opposite directions, thereby achieving contact with the thin-walled ring from both the inner and outer sides and clamping the thin-walled ring.

[0008] As a further limitation of this technical solution, the external gear and the internal gear are of the same model, which facilitates the reverse swinging of the inner and outer clamping columns with the same amplitude.

[0009] As a further limitation of this technical solution, a circular block is fixedly connected to the edge of each internal gear, and one end of each circular block is rotatably connected to a connecting rod. The other end of each connecting rod is rotatably connected to the corresponding limiting circular rod. By using the limiting circular rod and the connecting rod, the internal gear rotates when the swing arm swings, thereby realizing the rotation of the external gear and the swinging of the inner and outer clamping columns.

[0010] As a further limitation of this technical solution, the center plate bearing is connected to the power gear, and a set of transmission gears respectively mesh with the power gear. By using the method of transmission gears meshing with the power gear, the inner and outer clamping columns move synchronously when the power gear rotates.

[0011] As a further limitation of this technical solution, the clamp base is fixedly connected to a motor, the output shaft of the motor is fixedly connected to a turntable, a rocker arm is rotatably connected to the edge of the turntable, the rocker arm is fixedly connected to a power rod, and the power rod is rotatably connected to the edge of the power gear. By employing a motor, power is provided for the rotation of the power gear.

[0012] As a further limitation of this technical solution, the center plate is fixedly connected to a set of contact arms, which facilitates the placement of thin-walled circular parts.

[0013] As a further limitation of this technical solution, a set of contact arms are respectively fixedly connected to protective rings, and the protective rings are fixedly connected to the fixture base. By using protective rings, the gears are protected, preventing workers from contacting the gears and causing injury to workers or damage to the gears.

[0014] Compared with related technologies, the clamping device for processing medical device parts provided by this utility model has the following advantages:

[0015] (1) This device uses clamping columns that are evenly distributed along the circumference to facilitate the uniform clamping of thin-walled circular parts and avoid damage to them.

[0016] (2) This device uses a limiting round rod and a connecting rod to realize the rotation of the internal gear when the swing arm swings, thereby realizing the rotation of the external gear, realizing the swing of the inner and outer clamping columns, and realizing the uniform clamping of the thin-walled ring.

[0017] (3) This device uses a contact arm to facilitate the placement of thin-walled circular parts and uses a protective ring to protect the gears. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1: A clamping device for processing medical device parts includes: a clamping base 3, wherein a set of limiting rods 4 are fixedly connected to the clamping base 3, and each limiting rod 4 is fixedly connected to a center plate 5; a set of transmission gears 13, wherein the central shaft of each transmission gear 13 is bearing-connected to the center plate 5, and the central shaft of each transmission gear 13 is fixedly connected to a swing arm 12; and a set of symmetrical mounting discs 6, wherein the central shafts of the discs are bearing-connected to the corresponding swing arms 12, and a clamping post 7 is fixedly connected to the eccentric portion of each mounting disc 6. By using clamping posts 7 evenly distributed along the circumference, it is convenient to achieve uniform clamping of thin-walled ring parts and avoid damage to them.

[0027] Each outer mounting plate 6 has an external gear 8 fixedly connected to its central axis, and each inner mounting plate 6 has an internal gear 9 fixedly connected to its central axis. Each external gear 8 meshes with its corresponding internal gear 9. By using external gears 8 and internal gears 9, their meshing achieves opposite rotation, causing the inner and outer clamping posts 7 to swing in opposite directions, thus enabling them to contact the thin-walled ring from both the inner and outer sides and clamp the thin-walled ring.

[0028] The external gear 8 and the internal gear 9 are of the same model, which facilitates the reverse swinging of the inner and outer clamping columns 7 with the same amplitude.

[0029] Each of the internal gears 9 is fixedly connected to a circular block 10 at its edge. Each circular block 10 is rotatably connected to one end of a connecting rod 11, and the other end of each connecting rod 11 is rotatably connected to a corresponding limiting circular rod 4. By using the limiting circular rod 4 and the connecting rod 11, the internal gear 9 is rotated when the swing arm 12 swings, thereby realizing the rotation of the external gear 8 and the swinging of the inner and outer clamping columns 7.

[0030] The center plate 5 is connected to the power gear 14 by a bearing, and a set of transmission gears 13 respectively mesh with the power gear 14. By using the transmission gears 13 to mesh with the power gear 14, the inner and outer clamping columns 7 move synchronously when the power gear 14 rotates.

[0031] The clamp base 3 is fixedly connected to a motor 18, the output shaft of the motor 18 is fixedly connected to a turntable 17, a rocker arm 16 is rotatably connected to the edge of the turntable 17, the rocker arm 16 is fixedly connected to a power rod 15, and the power rod 15 is rotatably connected to the edge of the power gear 14. The motor 18 provides power for the rotation of the power gear 14.

[0032] The motor 18 is model JGB37-520.

[0033] The working principle of the clamping device for processing medical device parts provided by this utility model is as follows:

[0034] In the initial state, such as Figure 1As shown, the thin-walled ring is placed between the inner and outer clamping posts 7. The motor 18 is controlled to rotate, which drives the turntable 17 to rotate. The turntable 17 drives the rocker arm 16 to swing, which in turn drives the power rod 15 to swing. The power rod 15 drives the power gear 14 to rotate, which in turn drives the transmission gear 13 to rotate. The transmission gear 13 drives the swing arm 12 to swing, which in turn drives the mounting plate 6, clamping posts 7, external gear 8, internal gear 9, and circular block 10 to swing. The circular block 10 drives the connecting rod 11 to swing under the limiting action of the limiting circular rod 4, causing the connecting rod 11 to drive the circular block 10 to swing. The circular block 10 drives the internal gear 9 to rotate, and the external gear 8 meshes with the internal gear 9 to rotate. The external gear 8 and internal gear 9 drive the mounting plate 6 to rotate, and the mounting plate 6 drives the clamping post 7 to swing, so that the clamping post 7 clamps the lower middle part of the thin-walled ring, which facilitates the machining of notches in the upper part and circular holes in the side wall (such as...). Figure 6 (As shown).

[0035] Example 2: This example is a further elaboration based on Example 1. The central plate 5 is fixedly connected to a set of contact arms 2. By using contact arms 2, it is convenient to place the thin-walled ring parts.

[0036] A set of contact arms 2 are respectively fixedly connected to protective rings 1, and the protective rings 1 are fixedly connected to the clamp base 3. By using the protective rings 1, the gears are protected, preventing workers from coming into contact with the gears and causing injury to the workers or damage to the gears.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
