Description

Technical Field

[0001] The utility model relates to the field of door handle assembly, in particular to a riveting tool for a handle and a base. Background Art

[0002] The door handle is a common part in life. With the rapid development of the manufacturing industry, the demand for it is also increasing continuously. The traditional door handle assembly process mainly relies on manual operation. Since there are many parts in the base of the door handle and there are many spring parts inside, accidents often occur during the installation process, resulting in the unguaranteed qualified rate of product installation. For example, the Chinese invention patent with the publication number CN115302233A discloses an automatic assembly machine for handle slider springs. In this solution, an automated assembly structure is designed to assemble the handle base, reducing the consumption of human resources and improving the production efficiency of the handle base. However, after the slider spring of the handle base is installed, the handle still needs to be manually inserted into the handle base further. During this assembly process, the spring often spreads due to unstable force, resulting in low installation efficiency and unguaranteed product quality, and a large amount of labor costs need to be consumed.

[0003] Therefore, it is very necessary to develop a door handle assembly tooling that is convenient to assemble and has high production efficiency, which can not only guarantee the product quality but also improve the production efficiency. Summary of the Utility Model

[0004] Aiming at the deficiencies in the prior art, the utility model provides a riveting tooling that is convenient and efficient in assembly and saves labor costs.

[0005] To achieve the above object, a riveting tooling for a handle and a base is provided, which includes a frame, a driving device, a handle clamp, and a base jig. The driving device is arranged at the upper end of the frame, the handle clamp is arranged at the lower end of the frame, the base jig limits the base and is arranged at the output end of the driving device, the handle clamp clamps the handle, and a quick-release guide head is arranged on the handle. When assembling the workpiece, the output end of the driving device drives the base jig to press downwards, the quick-release guide head passes through the installation hole of the base, and the base is smoothly installed on the handle. After the installation is completed, the driving device drives the base jig to move upwards to return to the original position, and the quick-release guide head is removed from the handle.

[0006] Based on the above, the base fixture presses and positions the parts of the base to prevent the parts from scattering during the installation process, making the assembly process more stable and efficient. At the same time, a quick-release guide head is provided on the handle. The quick-release guide head will squeeze the parts in the base to the appropriate positions. Subsequently, the handle and the base are assembled. After the installation is completed, the quick-release guide head is removed. The quick-release guide head makes the assembly more convenient and concise, improves the assembly efficiency, and reduces the labor cost.

[0007] Furthermore, the base fixture includes a base mounting block and a limiting post. The base mounting block is made of metal and is provided with a groove that conforms to the outer contour of the base. The base mounting block is also provided with an embedded groove, and a magnetic suction cylindrical block is arranged in the embedded groove. The limiting post is fixedly fitted with a through hole provided at the upper end of the base mounting block. The top of the limiting post protrudes above the groove and positions the parts on the base.

[0008] Based on the above, the magnetic suction cylindrical block is embedded in the embedded groove, making the base mounting block magnetic. The base mounting block adsorbs the base in the groove by magnetic force, reducing the screw installation steps and making the installation more simple and fast. The limiting post presses and positions the parts in the base.

[0009] Furthermore, the driving device includes a cylinder and a guide plate. The guide plate is fixedly installed at the output end of the cylinder. Guide rods that are slidably fitted with the frame are arranged on the guide plate. The limiting post is fixedly installed at the lower end of the guide plate.

[0010] Based on the above, the cylinder is used to control the lifting of the base fixture. The guide rods and the guide plate make the movement of the cylinder more stable, improving the assembly efficiency and product quality.

[0011] Furthermore, the handle fixture includes a pressing plate. The pressing plate includes pressing plate a and pressing plate b. Pressing plate a is fixedly installed on the frame and is provided with a guiding through hole. A sliding rod is slidably fitted in the guiding through hole. A clamping cylinder is also fixedly installed on pressing plate a. A push plate is arranged at the output end of the clamping cylinder. The push plate and pressing plate b are fixedly connected through the sliding rod.

[0012] Based on the above, pressing plate a is fixedly installed on the frame, while pressing plate b presses the mold clamping plate, so that it is not necessary to readjust the position every time the handle is assembled, improving the work efficiency.

[0013] Further, the handle fixture further includes a mold clamping plate, the mold clamping plate is provided with a clamping groove matching the outer contour of the handle, the mold clamping plate clamps the handle in the clamping groove, and the mold clamping plate is respectively fixed on the pressing plate a and the pressing plate b by screws. The clamping cylinder is started to drive the pressing plate b by the sliding rod to clamp or loosen the mold clamping plate.

[0014] Based on the above, the mold clamping plate fixedly installs the handle on the clamping groove, enabling the handle to be stably assembled with the base and improving the stability of the assembly.

[0015] Further, a round hole is provided at the lower end of the limit post, and the quick-release guide head passes through the base and stays in the round hole.

[0016] Based on the above, the quick-release guide head passes through the base until it is inside the round hole, enabling the handle to be installed on the base.

[0017] Further, the guiding end of the quick-release guide head is conical, and the non-guiding end of the quick-release guide head has a clearance fit with the handle.

[0018] Based on the above, the guiding end being conical can better guide the handle. The quick-release guide head has a clearance fit with the handle, making it easier to remove the quick-release guide head from the handle after the product is assembled.

[0019] Further, the quick-release guide head can also be made of a magnetically-attractive metal material and is quickly installed on the handle through magnetic attraction.

[0020] Based on the above, the quick-release guide head can be magnetically adsorbed on the handle, and after the handle and the guide head are installed, it is convenient to disassemble the quick-release guide head from the handle.

[0021] To more clearly illustrate the above features of the present invention and the objectives to be achieved, the following further describes the present invention in conjunction with the accompanying drawings and specific embodiments. Description of the Drawings
