Description

Technical Field

[0001] This utility model relates to the field of gear processing tooling fixtures, and in particular to a high-efficiency rotary shuttle transmission gear riveting fixture. Background Technology

[0002] In the production and assembly process of rotary shuttle gears, the riveting process is crucial. It is necessary to fix the gears to the bushings, connecting discs and other matching parts by pressure to ensure that the structure is stable and the coaxiality meets the production standards after assembly. However, the existing riveting fixtures have poor coordination between the pressing mechanism and the clamping mechanism. When pressing, the gears are prone to deformation due to uneven clamping force, especially for thin rotary shuttle transmission gears, which have a high damage rate. At the same time, most fixtures rely on manual adjustment of the clamping position, which not only increases the labor intensity of operators, but also makes it difficult to ensure the consistency of each clamping, further affecting the stability of product quality.

[0003] Therefore, we propose a high-efficiency rotary shuttle gear riveting fixture. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a high-efficiency rotary shuttle gear riveting clamp. Through the anti-slip design of the anti-slip clamping plate and the stable clamping effect brought by the cross-shaped slider, scratches or indentations on the gear surface can be avoided during clamping. At the same time, the controllable pressing speed and pressure of the electric push rod can prevent gear deformation and cracking caused by excessive pressing or excessive pressure. This significantly reduces the damage rate of thin and high-precision rotary shuttle gears, improves product yield, and reduces material waste in the production process.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: A high-efficiency rotary shuttle gear riveting fixture includes a pressurizing assembly, with a clamping assembly at its front end. The clamping assembly includes a housing, with a fixed ring fixedly connected inside the housing. A worm gear is rotatably connected to the inner ring of the fixed ring, and a rotating ring is fixedly connected to the top of the worm gear. The top of the rotating ring has multiple arc-shaped grooves, and a limiting ring fixedly connected to the housing is located above the rotating ring. Multiple equally spaced sliders are slidably connected to the top of the limiting ring, with an anti-slip clamping plate fixedly connected to the top of each slider. A sliding rod that slides through the arc-shaped grooves is fixedly connected to the bottom of each slider, and the sliding rod passes through the limiting ring.

[0006] Furthermore, a motor is fixedly connected inside the housing and below the fixing ring.

[0007] Furthermore, the transmission end of the motor is fixedly connected to a worm gear that meshes with the worm wheel, and the end of the worm gear away from the motor is rotatably connected to the inner wall of the housing.

[0008] Furthermore, the pressurizing assembly includes a base fixedly installed at the bottom of the housing, a bracket fixedly connected to the rear end of the base, an electric push rod fixedly connected to the top end of the bracket, the transmission end of the electric push rod passing through the bottom end of the bracket and fixedly connected to a pressurizing head, and the pressurizing head being adapted to the anti-slip clamping plate.

[0009] Furthermore, the top end of the limiting ring is provided with a groove adapted to the slider.

[0010] Furthermore, the bottom end of the limiting ring is provided with a slot adapted to the sliding rod, and the slot is connected to the sliding groove.

[0011] Furthermore, the slider is cross-shaped.

[0012] In summary, this utility model has the following beneficial effects: The anti-slip design of the anti-slip clamping plate and the stable clamping effect provided by the cross-shaped slider can prevent scratches or indentations on the gear surface during clamping. At the same time, the controllable pressing speed and pressure of the electric push rod can prevent gear deformation and cracking caused by excessive pressing or excessive pressure, significantly reducing the damage rate of thin and high-precision rotary shuttle gears, improving product yield, and reducing material waste in the production process.

Detailed Implementation

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0017] Reference Figures 1 to 5 As shown, a high-efficiency rotary shuttle transmission gear riveting fixture is provided in a preferred embodiment of the present invention. It includes a pressurizing component 1, and a clamping component 2 is provided at the front end of the pressurizing component 1. The clamping component 2 includes a housing 201, a fixing ring 202 is fixedly connected inside the housing 201, a worm gear 209 is rotatably connected to the inner ring of the fixing ring 202, a rotating ring 203 is fixedly connected to the top of the worm gear 209, a plurality of arc-shaped grooves 204 are provided at the top of the rotating ring 203, a limiting ring 205 is fixedly connected to the housing 201 above the rotating ring 203, a plurality of equally spaced sliders 206 are slidably connected to the top of the limiting ring 205, an anti-slip clamping plate 207 is fixedly connected to the top of the sliders 206, and a sliding rod 208 that slides with the arc-shaped grooves 204 is fixedly connected to the bottom of the sliders 206. The sliding rod 208 passes through the limiting ring 205. The worm gear 209 drives the rotating ring 203 to rotate, causing the arc groove 204 to push the sliding rod 208 to move along the limiting ring 205, which in turn drives the slider 206 and the anti-slip clamping plate 207 to move closer to or further away from the gear, so as to achieve uniform clamping of multiple claws, ensure clamping stability and coaxiality of the gear, and avoid gear deviation during riveting.

[0018] A motor 210 is fixedly connected inside the outer casing 201 and below the fixing ring 202; The motor 210 provides stable power to drive the movement of components such as the worm gear 209 and the rotating ring 203, replacing manual drive, reducing the labor intensity of operators, and ensuring the stability and consistency of power output, thereby improving the accuracy of clamping actions. Among them, the transmission end of the motor 210 is fixedly connected to a worm 211 that meshes with the worm wheel 209, and the end of the worm 211 away from the motor 210 is rotatably connected to the inner wall of the outer casing 201. The rotational motion of the motor 210 is converted into the rotational motion of the worm wheel 209 through the meshing transmission of the worm 211 and the worm gear 209. At the same time, the self-locking function of the worm gear 209 and the worm 211 can prevent the parts from moving in the opposite direction after clamping, ensuring the stability of the clamping state and avoiding loosening of the clamping due to the reaction force during the riveting process.

[0019] The pressurizing component 1 includes a base 101 fixedly installed at the bottom of the housing 201. A bracket 102 is fixedly connected to the rear end of the base 101. An electric push rod 103 is fixedly connected to the top end of the bracket 102. The transmission end of the electric push rod 103 passes through the bottom end of the bracket 102 and is fixedly connected to a pressurizing head 104. The pressurizing head 104 is adapted to the anti-slip clamping plate 207. The base 101 and bracket 102 provide stable support for the electric push rod 103 and the pressure head 104, ensuring the structural stability of the pressure mechanism. The electric push rod 103 drives the pressure head 104 to move up and down, achieving precise pressure on the gear. The pressure head 104 is adapted to the anti-slip clamping plate 207 to ensure that the pressure position corresponds to the clamping position, thus ensuring riveting accuracy. The top of the limiting ring 205 is provided with a groove that is adapted to the slider 206; By restricting the sliding direction of the slider 206 through the slide groove, the slider 206 can only slide radially along the slide groove, avoiding the slider 206 from deviating or getting stuck during the sliding process, ensuring the synchronization and consistency of the movement of multiple sliders 206, and improving the clamping effect. The bottom end of the limiting ring 205 is provided with a slot adapted to the sliding rod 208, and the slot is connected to the sliding groove; The slot provides movement space for the sliding rod 208, ensuring that the sliding rod 208 can move smoothly with the rotation of the rotating ring 203. At the same time, the slot is connected to the slide groove, so that the sliding rod 208 can stably drive the slider 206 to slide, ensuring the continuity of the clamping action and avoiding the impact on clamping efficiency due to obstruction of component movement. The slider 206 is cross-shaped; By adapting the cross-shaped slider 206 to the groove of the limiting ring 205, the contact area between the slider 206 and the groove is increased, the stability of the slider 206 during sliding is improved, the slider 206 is prevented from flipping or tilting during sliding, and the anti-slip clamping plate 207 is always in a horizontal state, further improving the clamping accuracy and gear stability. Specific implementation process: First, place the rotary gear to be riveted at the center between the anti-slip clamping plates 207, ensuring that the part of the gear to be riveted faces upward and corresponds to the position of the pressure head 104. Then, start the motor 210, which drives the worm gear 211 to rotate. The worm gear 211 drives the meshing worm wheel 209 to rotate, and the rotating ring 203 fixedly connected to the worm wheel 209 rotates synchronously. The arc groove 204 on the rotating ring 203 pushes the sliding rod 208 to slide along the slot of the limiting ring 205. The sliding rod 208 drives the slider 206 to move along the sliding groove at the top of the limiting ring 205 towards the gear until the anti-slip clamping plate 207 is tightly attached to the gear. The gear is clamped by the wall, and the motor 210 stops working. The self-locking function of the worm gear 209 and worm 211 is used to maintain the clamping state. Then, the electric push rod 103 is started. The transmission end of the electric push rod 103 pushes the pressure head 104 to move downward, applying the set pressure to the part of the gear to be riveted, and completing the riveting operation. After the riveting is completed, the electric push rod 103 drives the pressure head 104 to return to the top, the motor 210 rotates in the opposite direction, and drives the worm 211, worm gear 209 and rotating ring 203 to move in the opposite direction. The sliding rod 208 drives the slider 206 and anti-slip clamping plate 207 away from the gear. The operator takes out the riveted gear, completing one riveting operation.
