The utility model belongs to graphite tool fixture technical field especially is a graphite tool fixture, including base, the upper surface fixed connection of base has workstation, the both sides of workstation are all set up with the sliding slot, the upper surface middle part fixed connection of base has fixed base, the upper surface both sides of fixed base are all fixed connection with slide rail, both sides of two slide rails are all slidingly connected with the sliding block, the upper surface fixed connection of two groups of sliding blocks has the connecting plate, one side of two connecting plates is all fixed connection with the fixed frame. The utility model discloses through drive electric telescopic link drive fixed plate sliding, make it pull the connecting plate and make the sliding block slide on the slide rail, and two connecting plates cooperate with the meshing mode of bilateral rack one and central fixed gear, can drive two connecting plates to move inwards simultaneously, realize the symmetrical clamping to work piece, avoid the stress uneven problem that partial clamping brings, improve the positioning accuracy, improve the clamping stability in the processing process.

The present application provides a clothing treatment apparatus comprising: a drum which has a drum body providing a space for storing clothes, a front cover forming a front surface of the drum body, a rear cover forming a rear surface of the drum body, a drum inlet provided to pass through the front cover, and a rear cover through-hole provided to pass through the rear cover; a motor which has a stator forming a rotating magnetic field and a rotor rotating by means of the rotating magnetic field; a fixed panel positioned between the rear cover and the motor; a fixed panel through-hole provided to pass through the fixed panel; a power transmission part which has a housing fixed to the fixed panel and to which the stator is fixed, an input shaft having one end fixed to the rotor and the other end positioned inside the housing, an output shaft having one end inserted into the fixed panel through-hole and the other end positioned inside the housing, and a gear unit positioned inside the housing and transmitting the rotational motion of the input shaft to the output shaft; a shaft fastening part fixed to the rear cover and closing the rear cover through-hole; a fastening part through-hole provided to pass through the shaft fastening part and into which one end of the output shaft is inserted; and a nut coupled to the one end of the output shaft passing through the fastening part through-hole and fixing the output shaft to the shaft fastening part.

This utility model discloses a sliding quick positioning assembly for metal guide rails, relating to the field of guide rail technology. It includes a guide rail body with a positioning mechanism. The positioning mechanism comprises a mounting frame, several cylinders, a push plate, several moving frames, a fixing pad, several moving cylinders, a moving column, and a support plate. The mounting frame is fixed to the bottom of both sides of the guide rail body. Several cylinders are fixedly mounted on one side of the mounting frame, with the cylinder output ends extending into the mounting frame. The push plate is fixedly mounted on the corresponding cylinder output end. In the technical solution provided by this utility model, by setting the positioning mechanism, the cylinders control the push plate to move laterally. The push plate supports the support plate, causing the moving frames and the fixing pads on them to move upwards. When the slider on the guide rail body is positioned, the fixing pads support the bottom of the slider, increasing damping, reducing the small displacement of the slider due to vibration, reducing the reverse rebound of the slider, shortening the stabilization time, and making the slider positioning faster and more stable.

The present application relates to a clothing treatment apparatus comprising: a drum which is provided with a drum body providing a space for storing clothing, a front cover forming the front surface of the drum body, a rear cover forming the rear surface of the drum body, and a rear cover through-hole passing through the rear cover; a fixing panel provided at a position spaced apart from the rear cover; a power transmission unit which is provided with a housing fixed to the fixing panel, an input shaft of which one end is positioned outside the housing and the other end is positioned inside the housing, an output shaft of which one end passes through the fixing panel and is fixed to the rear cover and the other end is positioned inside the housing, and a gear unit positioned inside the housing and transmitting the rotational motion of the input shaft to the output shaft; a motor which is provided with a stator fixed to the fixing panel or the housing and forming a rotating field and a rotor fixed to the one end of the input shaft and rotated by the rotating field; a support panel provided at a position spaced apart from the front cover; an input hole passing through the support panel; a drum connection body which protrudes from the support panel toward the front cover and is inserted into the drum input hole, and which surrounds the input hole; and a displacement-limiting part which is provided in the drum connection body and limits the displacement of the drum input hole with respect to the radial direction of the input hole.

The utility model discloses a highly integrated four-axis machining clamp which comprises a machining clamp base, a fitting plate is installed on the machining clamp base, first clamp assemblies are arranged on the outer walls of the two sides of the machining clamp base, and second clamp assemblies are further arranged on the outer walls of the two sides of the machining clamp base. An integrated workpiece is placed on the machining clamp base and installed and fixed through an attaching plate, a first clamp assembly and a second clamp assembly. The two first clamp assemblies are symmetrically arranged on the two sides of the base, each first clamp assembly clamps the middle positions of the two sides of the workpiece and is matched with the bottom attaching plate to form a stable three-point positioning structure, clamping force evenly acts on the two sides of the gravity center of the workpiece through the design, and local stress concentration caused by torque deviation in traditional four-corner fixing is avoided.
