Description

Technical Field

[0001] This utility model relates to the technical field of tensile testing devices, specifically to a material pulling device that facilitates adjustment of clamping force. Background Technology

[0002] Currently, most clamping and pulling devices on the market are highly specific, often designed for a particular type of object to ensure that clamping requirements are met.

[0003] For example, Chinese patent CN110044691A discloses a new material tensile property testing device that is easy to clamp, which is equipped with a slide rail and a clamping box and can perform tensile tests on various new materials.

[0004] However, in order to ensure a stable and reliable clamping effect under different test conditions and meet the tensile testing requirements of various materials, the components for adjusting the clamping force are too complex and not suitable for industrial production.

[0005] Based on this, the present invention designs a material pulling device that facilitates adjustment of clamping force to solve the above problems. Utility Model Content

The support base is fixedly mounted on the base; the middle part of the connecting plate is rotatably mounted on the upper side of the support base; both sides of the connecting plate are rotatably connected to one end of a connecting rod, and the other end of the connecting rod is rotatably connected to the synchronization plate.

[0011] Furthermore, the moving drive assembly includes a cylinder, a guide rail, a slider, and an H-shaped guide rail support frame. The cylinder is fixedly installed on the lower side of the left synchronization plate, and the output end of the cylinder is fixedly connected to the support base. The H-shaped guide rail support frame is fixedly installed on the base. The support base is fixedly installed in the middle of the H-shaped guide rail support frame, and the support base is fixedly connected to the H-shaped guide rail support frame. A guide rail is fixedly installed on the H-shaped guide rail support frame, and the guide rail is located on the lower side of the synchronization plate. Two sets of sliders slide on the upper limit of the guide rail, and the two sets of sliders are fixedly connected to the synchronization plates on the left and right sides, respectively.

[0012] Furthermore, the clamping drive module includes a support frame, a clamping frame, a second cylinder, a connecting rod, a first sliding sleeve, and an auxiliary stabilizing rod. The support frame is fixedly installed on the upper side of the synchronous plate; the clamping frame is fixedly installed on the upper side of the support frame; the fixed end of the second cylinder is fixedly installed on the outer side of the clamping frame; the output end of the second cylinder is fixedly connected to the middle of the connecting rod, and two sets of first sliding sleeves are limited and slid at both ends of the connecting rod; the auxiliary stabilizing rod is located on both sides of the connecting rod, one end of the auxiliary stabilizing rod is rotatably connected to one side of the connecting rod, and the other end of the auxiliary stabilizing rod is rotatably connected to one side of the clamping frame on the same side as the connecting rod.

[0013] Furthermore, the adjustable clamping module includes an adjustment module and a clamping module, with the adjustment module mounted on the clamping module and the clamping module mounted on the moving end of the connecting rod.

[0014] Furthermore, the adjustment module includes a second sliding sleeve and a bolt, with the bolt threaded onto the right side of the second sliding sleeve.

[0015] Furthermore, the clamping module includes a transmission rod, support rods, and a clamping block. One end of the transmission rod is rotatably connected to a sliding sleeve one, and the other end of the transmission rod is rotatably connected to a sliding sleeve two. Two sets of support rods are symmetrically and slidably mounted on the clamping frame. The upper limit sliding of the support rods is provided by a sliding sleeve two, and the end of the bolt abuts against the support rods.

[0017] Compared with the prior art, the advantages of this utility model are as follows: The device can adjust the clamping force. The sliding sleeve two is threadedly connected to the bolt. Rotating the bolt can adjust the position of the sliding sleeve two on the support rod, thereby adjusting the clamping force of the clamping block. This device is designed with corresponding limiting fixtures and clamping devices for specific components, improving operational accuracy. The end face of the clamping block is designed with a groove that matches the end face, achieving radial tight fitting clamping. The workpiece to be processed is placed on the fixture table and transported by a belt conveyor. The central limiting plate fits into the annular groove, thereby limiting the workpiece to be processed. The end face is located within the limiting groove, facilitating the positioning and clamping of the clamping block. The auxiliary stabilizing rod follows the sliding sleeve... The movement enhances the overall stability of the clamping frame. Initially, the clamping blocks are in an open state. When the workpiece to be processed is confined on the tooling table and transported to the designated position by the belt conveyor, cylinder one drives the synchronous plate to move to the right. The synchronous plate drives the left connecting rod to rotate, the connecting rod drives the connecting plate to rotate, the connecting plate drives the right connecting rod to rotate, and the right connecting rod drives the right synchronous plate to rotate, thus realizing the synchronous movement of the two synchronous plates towards the middle. When clamping the workpiece to be processed, cylinder two on the left drives the connecting rod to move to the right, and the sliding sleeve one moves to both sides of the connecting rod. The sliding sleeve one drives the support rod to move towards the middle through the transmission rod, thereby causing the clamping block to close and engage with the end face to complete the clamping.
