Abstract

This utility model discloses a hot riveting fixture, comprising a base, a pressure seat, and a hot riveting assembly. The base is used to place the workpiece, and the pressure seat can slide relative to the base to move closer to or away from the base. The hot riveting assembly includes a sliding rod, an elastic element, and a hot pressing element. The sliding rod is slidably disposed on the pressure seat. The elastic element is connected to the sliding rod and the pressure seat at both ends, and has a spring force that brings the sliding rod closer to the base. The hot pressing element is installed at the end of the sliding rod close to the base, and the hot pressing element dissipates heat to melt the workpiece when it contacts it. First, the workpiece is placed on the base, and then the pressure seat is pushed closer to the base, thereby causing the hot pressing element to contact the workpiece. The heat dissipated by the hot pressing element melts the workpiece, causing the contacted part of the workpiece to be hot-melted and formed. Because the elastic element has a spring force that brings the sliding rod closer to the base, and because the spring force of the elastic element determines the pressure applied by the hot pressing element to the workpiece, the pressure applied by the hot pressing element to the workpiece is maintained within an appropriate range, ensuring the quality of the hot riveting of the workpiece.

Description

Technical Field

[0001] This utility model relates to the field of hot riveting technology, and specifically to a hot riveting tooling. Background Technology

[0002] Hot riveting is a joining process that connects two or more parts. Existing hot riveting equipment can be found in patent application number CN202223247232.6. This hot riveting fixture includes a pressure block, a connecting piece, and a support platform. The pressure block is connected to a heat source through the connecting piece. The heated pressure block contacts the workpiece, thereby melting the part to be riveted. However, the pressure between the pressure block and the workpiece affects the quality of the final hot riveting. If the pressure applied by the pressure block to the workpiece is too high, the part of the workpiece to be riveted will deform too much. If the pressure applied by the pressure block to the workpiece is too low, the part of the workpiece to be riveted will not melt sufficiently.

[0003] Therefore, how to keep the pressure applied to the workpiece by the hot pressing component stable is a technical problem that urgently needs to be solved. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned technical deficiencies and propose a hot riveting tooling to solve the technical problem that the pressure applied to the workpiece by the hot pressing component in the prior art is difficult to maintain stable.

[0005] To achieve the above-mentioned technical objectives, the present invention adopts the following technical solution: This utility model provides a hot riveting fixture, which includes: A base, used to hold the workpiece; A pressure seat, which can slide relative to the base to move closer to or away from the base; and A hot riveting assembly includes a slide rod, an elastic element, and a hot pressing element. The slide rod is slidably disposed on the pressure base. The elastic element is connected to the slide rod and the pressure base at both ends and has an elastic force that brings the slide rod closer to the base. The hot pressing element is installed at the end of the slide rod close to the base and dissipates heat to heat-melt the workpiece when it contacts the workpiece.

[0006] In some embodiments, the pressure seat has a guide hole, and the slide rod is slidably disposed in the guide hole.

[0007] In some embodiments, the end of the slide rod away from the base has a blocking portion, the outer diameter of which is larger than the inner diameter of the guide hole, to prevent the slide rod from disengaging from the guide hole.

[0008] In some embodiments, the elastic element includes a spring, one end of which is connected to the blocking portion and the other end of which is connected to the pressure seat.

[0009] In some embodiments, a forming groove is provided at one end of the hot-pressed component near the base.

[0010] In some embodiments, the forming groove is a concave spherical groove.

[0011] In some embodiments, a through hole is provided axially inside the slide rod.

[0012] In some embodiments, the pressure base has a storage groove that communicates with the threading hole.

[0013] In some embodiments, the base has a positioning groove.

[0014] In some embodiments, there are multiple sets of the hot riveting components, and an array of multiple sets of the hot riveting components is disposed on the pressure base.

[0015] Compared with the prior art, the hot riveting fixture provided by this utility model has the following advantages: First, the workpiece is placed on the base. Then, the pressure seat is pushed close to the base, causing the hot press component to contact the workpiece. The heat emitted by the hot press component melts the workpiece, forming the contact area. Because the elastic component has a spring force that pulls the slide bar closer to the base, and this spring force determines the pressure applied by the hot press component to the workpiece, the pressure is maintained within an appropriate range, ensuring the quality of the hot riveting process.

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0018] To address the technical problem of unstable pressure applied to the workpiece by the hot pressing component, this utility model provides a hot riveting fixture that can use an elastic component to regulate the pressure applied to the workpiece by the hot pressing component, so that the pressure applied to the workpiece by the hot pressing component is maintained within an appropriate range.

[0019] It should be noted that the hot riveting fixture of this utility model is used for hot riveting of workpieces. For ease of explanation, this utility model will only use the application of the hot riveting fixture to hot riveting of workpieces as an example for explanation.

[0020] Please see Figure 1 , Figure 1 This is a schematic diagram of the structure of a hot riveting fixture in one embodiment of the present invention. The hot riveting fixture includes a base 100, a pressure seat 200, and a hot riveting assembly 300. The base 100 is used to place the workpiece. The pressure seat 200 can slide relative to the base 100 to move closer to or away from the base 100. The hot riveting assembly 300 includes a slide rod 310, an elastic element 320, and a hot pressing element 330. The slide rod 310 is slidably disposed on the pressure seat 200. The elastic element 320 is connected to the slide rod 310 and the pressure seat 200 at both ends, and has an elastic force that makes the slide rod 310 move closer to the base 100. The hot pressing element 330 is installed at the end of the slide rod 310 that is close to the base 100. The hot pressing element 330 dissipates heat to heat-melt the workpiece when it comes into contact with it.

[0021] In this embodiment, the workpiece is first placed on the base 100, and then the pressure seat 200 is pushed close to the base 100, thereby causing the hot pressing component 330 to contact the workpiece. The heat emitted by the hot pressing component 330 then heat-melts the workpiece, causing the contacted portion of the workpiece to be heat-melted and formed. Because the elastic component 320 has a spring force that brings the slide rod 310 close to the base 100, the spring force of the elastic component 320 determines the pressure applied by the hot pressing component 330 to the workpiece, ensuring that the pressure applied by the hot pressing component 330 to the workpiece is maintained within an appropriate range, thus guaranteeing the quality of the hot riveting of the workpiece.

[0022] In some embodiments, the pressure seat 200 has a guide hole 210, and the slide rod 310 is slidably disposed in the guide hole 210. Guided by the guide hole 210, the slide rod 310 can move along the axial direction of the guide hole 210, thereby allowing the slide rod 310 to slide relative to the pressure seat 200.

[0023] Based on the above embodiments, in some embodiments, the end of the slide rod 310 away from the base 100 has a blocking portion 311. The outer diameter of the blocking portion 311 is larger than the inner diameter of the guide hole 210 to prevent the slide rod 310 from disengaging from the guide hole 210. Since the outer diameter of the blocking portion 311 is larger than the inner diameter of the guide hole 210, the blocking portion 311 cannot pass through the guide hole 210, thereby preventing the slide rod 310 from disengaging entirely from the guide hole 210.

[0024] In some embodiments, the elastic element 320 includes a spring 321, one end of which is connected to the blocking part 311, and the other end is connected to the pressure seat 200. Since the two ends of the spring 321 are connected to the blocking part 311 and the pressure seat 200 respectively, when the hot pressing element 330 contacts the workpiece, it drives the sliding rod 310 to move relative to the pressure seat 200, thereby causing the sliding rod 310 to compress the spring 321. The reaction force of the spring 321 determines the pressure applied to the workpiece by the hot pressing element 330, thereby maintaining the pressure applied to the workpiece by the hot pressing element 330 within a suitable range.

[0025] In some embodiments, the hot press 330 has a forming groove 331 at one end near the base 100. After the hot press 330 melts the workpiece, the molten material accumulates in the forming groove 331, and the inner wall of the forming groove 331 can shape the molten material.

[0026] Based on the above embodiments, in some of the embodiments, the forming groove 331 is a concave spherical groove.

[0027] It is understood that the hot press component 330 is typically an electrothermal hot press component 330, and therefore requires power supply. In some embodiments, a through hole 312 is provided axially inside the slide rod 310, through which the power supply wire of the hot press component 330 can be passed through the through hole 312, so that the power supply wire of the hot press component 330 is connected to the power supply element of the pressure base 200.

[0028] Based on the above embodiments, in some embodiments, the pressure base 200 is provided with a storage groove 220 that connects to the wire threading hole 312, and the power supply components and part of the power supply wires can be stored in the storage groove 220.

[0029] In some embodiments, the base 100 has a positioning groove 110. The positioning groove 110 can limit the workpiece, thereby fixing the workpiece to be processed.

[0030] In some embodiments, there are multiple sets of hot riveting components 300, and the array of multiple sets of hot riveting components 300 is arranged on the pressure base 200, so that multiple parts can be hot riveted at the same time.

[0031] To better understand this utility model, the following is combined with... Figures 1 to 3 The technical solution of this utility model is described in detail below: First, the workpiece is placed in the positioning groove 110, which limits its movement and fixes it to the base 100. Then, the pressure seat 200 is pushed closer to the base 100, causing the hot press component 330 to contact the workpiece. The heat emitted by the hot press component 330 melts the workpiece, and the molten material accumulates in the forming groove 331. The inner wall of the forming groove 331 then shapes the molten material until the contacted part of the workpiece is hot-melted and formed. Because the elastic component 320 has a spring force that brings the slide rod 310 closer to the base 100, this spring force determines the pressure applied by the hot press component 330 to the workpiece, maintaining the pressure within an appropriate range and ensuring the quality of the hot riveting process.
