Description

Technical Field

[0001] This utility model relates to the technical field of transmission structures, and in particular to the angle conversion mechanism of the reciprocating motion conjugate cam of the clamp. Background Technology

[0002] Traditional technologies require the conversion of motor rotational motion into linear reciprocating motion, and also require changes in transmission direction. This often relies on the coordination of multiple planar gears, spiral bevel gears, and swing arms. However, gears and similar structures are not suitable for installation in some existing environments, and the existing technologies require a large amount of space and are costly. Therefore, existing transmission structures cannot meet current needs. Utility Model Content

[0003] The purpose of this invention is to solve the problems in the prior art by proposing an angle conversion mechanism for a reciprocating conjugate cam of a clamp. This mechanism can convert the rotational force of the conjugate cam into a force that drives the clamp seat to move back and forth. The direction of motion is changed through the cooperation of each swing arm and pull rod, resulting in stable transmission and meeting the needs of environments where gears cannot be installed.

[0004] To achieve the above objectives, this utility model proposes an angle conversion mechanism for a reciprocating conjugate cam of a clamp, comprising a conjugate cam and a transmission rocker arm cooperating with the conjugate cam. The middle part of the transmission rocker arm is hinged and fixed by a first rocker arm seat. A connecting rod is provided at one end of the transmission rocker arm away from the conjugate cam. The connecting rod is hinged to the transmission rocker arm. A conversion rocker arm is provided at the other end of the connecting rod. One end of the conversion rocker arm is hinged to the connecting rod, and the other end is hinged to the clamp seat. The conversion rocker arm is hinged and fixed by a second rocker arm seat. The transmission rocker arm and the conversion rocker arm are respectively arranged in different directions.

[0005] Preferably, the switching rocker arm is also provided with a return spring for driving it to flip to one side around the second rocker arm seat.

[0006] Preferably, a tension spring base plate for fixing the reset spring is provided next to the second rocker arm seat.

[0007] Preferably, the clamp seat is provided with a connecting slot, and the conversion rocker arm is provided with a connecting bearing for detachable connection with the connecting slot.

[0008] Preferably, the transmission rocker arm is vertically oriented, the connecting rod is horizontally oriented left and right, the conversion rocker arm is horizontally oriented front and back, and the orientation of the transmission rocker arm is perpendicular to the orientation of the conversion rocker arm.

[0009] Preferably, the transmission rocker arm includes a primary rocker arm and a secondary rocker arm disposed on one side of the primary rocker arm, the conjugate cam is disposed between the primary rocker arm and the secondary rocker arm, and the connecting rod is connected to the primary rocker arm.

[0010] Preferably, the connecting rod includes a rod body and joint bearings respectively disposed at both ends of the rod body. The joint bearings at both ends are respectively hinged to the transmission rocker arm and the conversion rocker arm. The rod body and the joint bearings are connected by threads.

[0011] The beneficial effects of this utility model's angle conversion mechanism for a reciprocating conjugate cam in a clamp are as follows: This utility model uses the rotation of the conjugate cam to drive the swing arm, which in turn drives the connecting rod to move laterally left and right. The connecting rod transmits force to the conversion rocker arm, which in turn drives the clamp seat to move forward and backward. This structure converts the rotational force of the conjugate cam into a force that drives the clamp seat to move forward and backward. The rotation of the conjugate cam enables the clamp seat to move continuously and stably forward and backward. The direction of motion is changed through the cooperation of the various swing arms and connecting rods. The transmission is stable, has a large transmission torque, low noise, saves equipment space and cost, and eliminates the need for spiral bevel gears, thus saving equipment space and cost. It also meets the needs of environments where gears cannot be installed.

[0012] The features and advantages of this utility model will be described in detail through embodiments and accompanying drawings. Attached Figure Description

[0023] See Figure 1 , Figure 2This utility model discloses an angle conversion mechanism for a reciprocating conjugate cam of a clamp, comprising a conjugate cam 1 and a transmission rocker arm 2 that is driven and fed by the conjugate cam 1. The middle part of the transmission rocker arm 2 is hinged and fixed by a first rocker arm seat 3. A connecting rod 4 is provided at one end of the transmission rocker arm 2 away from the conjugate cam 1. The connecting rod 4 is hinged to the transmission rocker arm 2. A conversion rocker arm 5 is provided at the other end of the connecting rod 4. One end of the conversion rocker arm 5 is hinged to the connecting rod 4, and the other end is hinged to the clamp seat 6. The conversion rocker arm 5 is hinged and fixed by a second rocker arm seat 7. The transmission rocker arm 2 is vertically arranged, the connecting rod 4 is horizontally arranged in the left-right direction, and the conversion rocker arm is horizontally arranged in the front-back direction. The direction of the transmission rocker arm 2 is perpendicular to the direction of the conversion rocker arm 5. In this embodiment, the rotation of the conjugate cam 1 drives the swing arm 2 to swing, thereby causing the connecting rod 4 to move laterally left and right. The connecting rod 4 transmits force to the conversion rocker arm 5, which in turn drives the clamp seat 6 to move back and forth. The structure of this application can convert the rotational force of the conjugate cam 1 into a force that drives the clamp seat 6 to move back and forth. The rotation of the conjugate cam 1 can drive the clamp seat 6 to move back and forth continuously and stably. The direction of motion is changed by the cooperation of each swing arm and the connecting rod. The transmission is stable, the transmission torque is large, the noise is low, and the equipment space and cost are saved. It does not require spiral bevel gears, thus saving equipment space and cost and meeting the needs of some environments where gears cannot be installed.

[0024] For details, please refer to Figure 1 , Figure 2 The conversion rocker arm 5 is also provided with a return spring 8 for driving it to rotate to one side around the second rocker arm seat 7.

The conjugate cam 1 is disposed between the active rocker arm 21 and the passive rocker arm 22. The connecting rod 4 is connected to the active rocker arm 21.

[0026] Example 2:

[0027] See Figure 3 , Figure 4 Based on Embodiment 1, the clamp seat 6 is provided with a connecting slot 61, and the conversion rocker arm 5 is provided with a connecting bearing 51 for detachable connection with the connecting slot 61. The connecting slot 61 is an open design, and the clamp seat 6 is connected to the conversion rocker arm 5 through the connecting slot 61. The detachable design makes it easier to connect and separate the two.

[0028] See Figure 1 , Figure 2 The connecting rod 4 includes a rod body 41 and spherical bearings 42 respectively located at both ends of the rod body 41. The spherical bearings 42 at both ends are hinged to the transmission rocker arm 2 and the conversion rocker arm 5, respectively. The rod body 41 and the spherical bearings 42 are connected by threads. This threaded connection allows for adjustment of the connection position between the rod body 41 and the spherical bearings 42, thereby enabling adjustment of the overall length of the connecting rod 4 to meet various usage requirements.
