Description

Technical Field

[0001] The invention relates to the technical field of connecting devices, and in particular to a slide rail type riveting tool. Background Art

[0002] Riveting is a common mechanical connection method. It usually uses a punch, a mold and a rivet tool to insert the rivet into two or more workpieces and deform the two ends of the rivet through pressure to achieve a fixed connection between the workpieces.

[0003] In the existing riveting process, it is usually necessary to manually feed the product into the riveting mold, and then the mold is closed to rivet the product. If the operator does not take his hands out from between the upper and lower molds when closing the molds, it will cause squeezing and damage to the operator's hands, which poses certain safety hazards. In addition, some methods move the lower mold out from under the upper mold, and after placing the product, push the lower mold to the bottom of the lower mold for riveting. Although this method has certain safety, it requires manual pushing and pulling of the lower mold, which is time-consuming and inefficient. For this reason, we propose a slide rail riveting tool. Summary of the invention

[0004] The purpose of the present invention is to provide a slide rail type riveting tool to solve the problems raised in the above background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a slide rail type riveting tool, comprising:

[0006] A mounting base, wherein a guide rod is fixed on the mounting base, a fixing plate is slidably connected to the guide rod, and an upper mold is provided on the lower surface of the fixing plate;

[0007] At least two guide blocks are symmetrically arranged in the middle of the upper surface of the mounting base;

[0008] A movable plate is slidably mounted between the two guide blocks, and a sliding assembly is detachably connected to the lower surface of the movable plate;

[0009] The transmission mechanism is arranged on the guide block to pull the movable plate to automatically move out from under the upper mold when the upper mold rises.

[0010] Preferably, the transmission mechanism includes a wire rope, a pulley assembly, a connecting slider, a first adjusting slider, a spring, a second adjusting slider and a first adjusting screw. The connecting slider is slidably installed on the inner side of the guide block, and one end of the connecting slider is fixed to the movable plate, one side of the connecting slider is connected to the first adjusting slider through the first adjusting screw, a wire rope is fixed to one side of the first adjusting slider, and one end of the wire rope cooperates with the upper mold through the pulley assembly, and the other side of the connecting slider has a spring.

[0011] Preferably, the pulley assembly includes a first pulley, a wire rope, a guide pulley and a second pulley, the guide pulley and the second pulley are arranged side by side on the guide block, the side wall of the upper mold is provided with an ear plate, and the first pulley is rotatably installed on the lower surface of the ear plate, and the other end of the wire rope cooperates with the first pulley.

[0012] Preferably, a second adjusting slider is slidably provided at one end of the inner side of the guide block, and a side wall of the second adjusting slider is in contact with the spring, a second adjusting screw is rotatably provided at the other side of the second adjusting slider, and a threaded portion cooperating with the guide block is provided on the outer surface of the second adjusting screw.

[0013] Preferably, the guide block has an L-shaped cross section, and a wear-resistant plate is provided on one side of the guide block corresponding to the movable plate.

[0014] Preferably, a groove is formed on one side wall of the wear-resistant plate, and a ball bearing is arranged inside the groove.

[0015] Preferably, a positioning groove is provided on one side wall of the wear-resistant plate, a protrusion matching with the positioning groove is provided on one side wall of the guide block, and limiting bolts connected with the protrusions are provided at both ends of the inner side of the wear-resistant plate.

[0017] Preferably, the supporting sliding block is made of Teflon.

[0018] Preferably, a micro switch corresponding to one end of the movable plate is provided on the edge of the upper surface of the mounting base.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] The present invention provides a sliding movable plate, a guide block and a transmission mechanism, thereby avoiding the situation in which the conventional movable plate is directly fixed to the workbench of the punch press through a mounting base. When riveting to raise and lower products, the operator's hand needs to be inserted between the upper mold and the movable plate, which poses a risk of extrusion. The present invention is easy to operate and has high safety. During the process of raising and lowering products, the movable plate can be automatically moved out from under the upper mold, and then the products can be raised and lowered, thereby improving efficiency. In addition, the movable plate is contacted with the microswitch to detect whether the movable plate is in place. Only after the movable plate is in place can the punch press work. The present invention can also well prevent the upper and lower molds from being damaged due to improper closing, thereby improving the practicability of the device.
