UTILITY MODEL CONTENTS

[0005] In view of the defects of the prior art, the utility model provides a pipeline riveting equipment, which solves the problem of lack of structure for clamping and fixing the pipeline, and the riveting head will be bent or inclined due to the extrusion of the riveting head when riveting, which affects the riveting effect.

[0006] To achieve the above object, the utility model provides the following technical scheme: a pipeline riveting equipment, which comprises a base, the top surface of the base is fixedly connected with a positioning block, a through hole is formed in the side surface of the positioning block, a plurality of sleeve holes are uniformly distributed in the inner circumferential surface of the through hole, a spring is sleeved in each sleeve hole, and the end portion of the spring is fixedly connected with a clamping plate; a clamping assembly is arranged outside the through hole, an installation block is fixedly arranged on the other side of the top surface of the base, a telescopic rod is fixedly connected to the back surface of the installation block, and the movable end of the telescopic rod penetrates through the installation block and is connected with a push plate;

[0007] The clamping assembly comprises a circular ring fixed outside the through hole, a threaded hole is formed in the circumferential surface of the circular ring, a bolt is screw-connected in the threaded hole, a bearing is sleeved on the end portion of the bolt, and the outer side surface of the bearing is fixedly connected with an extrusion plate.

[0008] In one specific embodiment, the end of the bolt away from the extrusion plate is provided with an operating handle, and the surface of the operating handle is provided with anti-slip texture.

[0009] In one specific embodiment, the telescopic rod adopts a hydraulic cylinder structure, and the end of the piston rod of the hydraulic cylinder is fixedly connected to the push plate.

[0010] In one specific embodiment, the clamping surface of the clamping plate has an arc-shaped structure, and the arc-shaped surface is provided with anti-slip teeth.

[0011] In a specific embodiment, the push plate has an arc-shaped groove on its pushing end face that matches the outer diameter of the rivet head, and the surface of the arc-shaped groove is provided with knurled anti-slip texture.

[0012] In one specific embodiment, the bottom of the base is provided with an anti-slip rubber pad, and the surface of the anti-slip rubber pad is provided with staggered raised stripes.

[0013] Compared with the prior art, the present invention provides a pipe riveting device, which has the following beneficial effects:

[0014] In the technical solution disclosed in this utility model, the spring and clamping plate in the through hole of the positioning block constitute an adaptive elastic clamping structure, which can pre-tighten and fix workpieces of different diameters. Combined with the active locking mechanism of the bolt driving the extrusion plate to abut the pipe fitting in the clamping assembly, the bearing realizes rotational pressure and uniform force.

[0015] The positioning block and clamping assembly of this invention allow the pipe fitting to be inserted into the through hole of the positioning block. The arc-shaped clamping surface of the clamping plate is pressed tightly against the pipe wall under the push of the spring, and the anti-slip teeth are embedded in the surface of the pipe fitting to form an initial clamping force. At this time, the pipe fitting can be manually fine-tuned to adjust its centering position. Rotating the bolt of the clamping assembly causes the extrusion plate to advance radially along the pipe fitting, and its arc-shaped surface further presses the pipe fitting until the bolt reaches the preset torque value. At this time, the pipe fitting is completely locked, and the clamping force is significantly improved. Activating the telescopic rod causes the hydraulic cylinder to drive the arc-shaped groove of the push plate to move, sending the rivet head into the pipe fitting. The riveting force is evenly transmitted to the pipe fitting through the double clamping structure, achieving a high-precision riveting effect. This effectively increases the stability of the pipe clamping and prevents bending or displacement that would affect the riveting effect. Attached Figure Description

[0022] The following will describe in detail the implementation of this application with reference to the accompanying drawings and embodiments, so that the implementation process of how this application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0023] Figures 1-4 In one embodiment of this utility model, a pipe riveting device includes a base 1. A positioning block 2 is fixedly connected to one side of the top surface of the base 1. A through hole is opened on the side of the positioning block 2. Several sleeve holes are evenly distributed in the circumferential direction inside the through hole. A spring 3 is sleeved in each sleeve hole. A clamping plate 4 is fixedly connected to the end of the spring 3. A clamping component 5 is provided outside the through hole. An installation block 6 is fixedly provided on the other side of the top surface of the base 1. A telescopic rod 7 is fixedly connected to the back of the installation block 6. The movable end of the telescopic rod 7 passes through the installation block 6 and is connected to a push plate 8.

[0024] The specific problem addressed in this embodiment is the lack of a structure for clamping and fixing pipelines, which leads to bending or deflection due to the pressure of the rivet head during riveting, affecting the riveting effect. This invention utilizes a spring 3 within the through hole of the positioning block 2 and a clamping plate 4 to form an adaptive elastic clamping structure, enabling pre-tightening and fixing of workpieces of different diameters. Combined with the active locking mechanism of the bolt 52 driving the pressing plate 54 to abut against the pipe fitting in the clamping assembly 5, rotational pressure and uniform force are achieved through the bearing 53.

[0025] The clamping assembly 5 includes a ring 51 fixed to the outside of the through hole. The ring 51 has a threaded hole around its circumference. A bolt 52 is threaded into the threaded hole. A bearing 53 is sleeved on the end of the bolt 52. A pressing plate 54 is fixedly connected to the outer side of the bearing 53. A mounting block 6 is fixedly provided on the other side of the top surface of the base 1. A telescopic rod 7 is fixedly connected to the back of the mounting block 6. The movable end of the telescopic rod 7 passes through the mounting block 6 and is connected to a push plate 8. In this specific embodiment, the telescopic rod 7 adopts a hydraulic cylinder structure. The piston rod end of the hydraulic cylinder is fixedly connected to the push plate 8. Insert the pipe fitting into the through hole of the positioning block 2. The arc-shaped clamping surface of the clamping plate 4 is pressed tightly against the pipe wall under the push of the spring 3. The anti-slip teeth are embedded in the surface of the pipe fitting to form an initial clamping force. At this time, the pipe fitting can be manually fine-tuned to adjust the centering position. Rotate the bolt 52 of the clamping assembly 5. The extrusion plate 54 is pushed radially along the pipe fitting. Its arc-shaped surface further presses the pipe fitting until the bolt 52 reaches the preset torque value. At this time, the pipe fitting is completely locked and the clamping force is significantly improved. Start the telescopic rod 7. The hydraulic cylinder drives the arc-shaped groove of the push plate 8 to move and send the rivet head into the pipe fitting. The riveting force is evenly transmitted to the pipe fitting through the double clamping structure to achieve a high-precision riveting effect. This effectively increases the stability of the pipe clamping and avoids bending or displacement that would affect the riveting effect.

[0026] In this specific embodiment, the pushing end face of the push plate 8 is provided with an arc-shaped groove that matches the outer diameter of the rivet head, and the surface of the arc-shaped groove is provided with knurled anti-slip texture. The arc-shaped groove on the pushing end face of the push plate 8 fits completely with the outer wall of the rivet head, and the knurled anti-slip texture increases the coefficient of friction, ensuring that the riveting force transmitted by the hydraulic telescopic rod 7 is evenly applied to the pipe fitting, avoiding the slippage phenomenon of traditional flat push plates. At the same time, the arc-shaped clamping surface and anti-slip teeth of the clamping plate 4 further increase the radial clamping stability, forming a two-way anti-slip system.

The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
