Abstract

The invention provides a tensile test machine horizontal sliding hydraulic clamp and relates to a tensile test machine clamp. A base is provided with a left and right oil cylinders, a left clamping piston and a right clamping piston are separately arranged in the left and right oil cylinders, a left chuck base and a right chuck base are separately arranged on the left and right clamping pistons, a left piston rod and a right piston rod are separately arranged on the left and right clamping pistons, a left connection plate and a right connection plate are separately arranged on the left and right piston rods, a left synchronous spline and a right synchronous spline are separately arranged on the left and right connection plates, synchronous gears are arranged on the outside of the oil cylinders, and the left and right synchronous splines are engaged with the synchronous gears. When the left and right synchronous splines of the clamp workpiece are under stress, the linking section can not fracture so that the clamp is stable to use; in addition, the base and the oil cylinders are not needed to disassemble in maintenance so that the tensile test machine horizontal sliding hydraulic clamp simplifies the maintenance, saves time and labor and is applicable to the tensile test machine.

Description

Tensile test machine horizontal sliding hydraulic clamp

Technical field

The present invention relates to the tension test machine clamp, is a kind of tensile test machine horizontal sliding hydraulic clamp specifically.

Background technology

We know, existing tension test machine clamp, be on base, to be provided with left oil cylinder and right oil cylinder, be respectively equipped with left clamping piston and right clamping piston in left side oil cylinder and the right oil cylinder, left side clamping piston and right clamping piston below are respectively equipped with left pin and right pin, left side pin and right pin below are respectively equipped with a left side tooth bar and right tooth bar synchronously synchronously, base inside is provided with synchronizing channel, be provided with synchromesh gear in the synchronizing channel, a left side synchronous tooth bar of the tooth bar and the right side synchronously is meshed with synchromesh gear in synchronizing channel.This tension test machine clamp, because left clamping piston and right clamping piston below are respectively equipped with left pin and right pin, left side pin and right pin below are respectively equipped with a left side tooth bar and right tooth bar synchronously synchronously, when the synchronous tooth bar of the synchronous tooth bar in a cupping machine clamp workpiece left side and the right side is stressed, link left side pin and right pin easy fracture, dependability is poor; Because base inside is provided with synchronizing channel, is provided with synchromesh gear in the synchronizing channel, left side tooth bar synchronously is meshed with synchromesh gear in synchronizing channel with right tooth bar synchronously, need dismantle base and oil cylinder during maintenance, and the maintenance trouble wastes time and energy.

Summary of the invention

The technical matters that the present invention solves is, solves clamping work pieces left side tooth bar and right synchronously when tooth bar is stressed synchronously, the link easy fracture; Need dismantle base and oil cylinder during maintenance, maintenance bothers, the problem that wastes time and energy, and when providing synchronous tooth bar in a kind of clamping work pieces left side and right synchronous tooth bar stressed, connecting portion can not rupture, and uses reliably; Do not need to dismantle base and oil cylinder during maintenance, keep in repair easy, time saving and energy saving tensile test machine horizontal sliding hydraulic clamp.

Technical scheme of the present invention is, base is provided with left oil cylinder and right oil cylinder, be respectively equipped with left clamping piston and right clamping piston in left side oil cylinder and the right oil cylinder, correspondence is provided with left base of the carrier head and right base of the carrier head on left side clamping piston and the right clamping piston, be respectively equipped with left chuck piece and right chuck piece on left side base of the carrier head and the right base of the carrier head, the primary structure characteristics are, be respectively equipped with left piston bar and right piston rod on left side clamping piston and the right clamping piston, be respectively equipped with left web joint and right web joint on left piston bar and the right piston rod, be respectively equipped with a left side tooth bar and right tooth bar synchronously synchronously on left side web joint and the right web joint, the oil cylinder outside is provided with synchromesh gear, and left side tooth bar synchronously is meshed with synchromesh gear with right tooth bar synchronously.

The invention has the beneficial effects as follows, owing to be respectively equipped with left piston bar and right piston rod on left clamping piston and the right clamping piston, be respectively equipped with left web joint and right web joint on left piston bar and the right piston rod, be respectively equipped with a left side tooth bar and right tooth bar synchronously synchronously on left side web joint and the right web joint, when synchronous tooth bar in a clamping work pieces left side and right synchronous tooth bar are stressed, link can not rupture, and uses reliable; Because the oil cylinder outside is provided with synchromesh gear, left side tooth bar synchronously is meshed with synchromesh gear with right tooth bar synchronously, does not need to dismantle base and oil cylinder during maintenance, keeps in repair easy, time saving and energy saving.The present invention is applicable to cupping machine.
