The invention discloses a bearing ring production device and method for bearing production, and particularly relates to the technical field of bearing production.The bearing ring production device comprises a device base, a rotating and fixing device is fixedly installed on one side of the top end of the device base, and a machining mechanism is fixedly installed on the side, close to the rotating and fixing device, of the top end of the device base; a feeding mechanism is fixedly installed on the side, close to the rotating and fixing device, of the top end of the device base, and a conveying mechanism is arranged between the feeding mechanism and the rotating and fixing device. According to the bearing ring blank machining device, the rotating and fixing device is arranged and used in cooperation with the machining mechanism, a plurality of outer shrinkage fixing rods can be used for externally positioning a bearing ring blank so that the inner side of the bearing ring blank can be comprehensively machined, and a plurality of inner expansion fixing rods can be used for internally positioning the bearing ring blank so that the outer side of the bearing ring blank can be comprehensively machined; and the clamping part of the bearing ring blank does not need to be adjusted back and forth, so that the bearing ring blank can be comprehensively turned, and the machining efficiency of the bearing ring is improved.

This utility model discloses a turning table with easily adjustable height, including a base and first hydraulic cylinders. The first hydraulic cylinders are symmetrically arranged at the top of the base, and each first hydraulic cylinder has a first push arm mounted on its output end. Each push arm has a bearing block mounted on its top end. An adjusting plate is arranged above the base, and both ends of the adjusting plate are provided with connecting shafts. The adjusting plate is movably connected to the bearing blocks via the connecting shafts. A servo motor is arranged on the outer wall of a set of bearing blocks, and the output end of the servo motor is equipped with a first worm gear, which is movably connected to the bearing blocks. A first worm wheel is fitted onto the surface of the connecting shaft on one side of the first worm gear. This utility model not only achieves center clamping and fixing of the workpiece and flexible adjustment of the workpiece's position and angle in both horizontal and vertical directions, facilitating workpiece height adjustment and flexible machining operations, but also improves the flexibility of workpiece machining.

The application relates to the elevator technical field and discloses a detachable manual turning gear mechanism of a hoisting machine, the hoisting machine being provided with a machine base and a steel belt driving shaft protruding on the machine base, a plurality of mounting parts being arranged on the machine base, the manual turning gear mechanism comprising: a turning gear, provided with an insertion hole; a protection switch, comprising a switch socket and a switch plug, the switch plug being slidably arranged on the switch socket, the switch plug being provided with a baffle; when the switch plug is inserted on the switch socket, the baffle can block the turning gear outside the steel belt driving shaft; when the switch plug is slid outward to be separated from the switch socket, the turning gear can be detachably arranged on the steel belt driving shaft along the steel belt driving shaft; a turning handle shaft, comprising a rotating shaft and a handle, the rotating shaft being provided with a driving gear engaged with the turning gear. The application has the advantages that the turning gear can be quickly and conveniently detached and assembled, can be turned in multiple directions, one turning gear is suitable for multiple hoisting machines, and the safety performance is good.

The utility model discloses an orthopedics rehabilitation training walking protection device which comprises an annular frame and a fixing ring, the fixing ring is arranged in the annular frame, a plurality of groups of upper outer fixing buckles are installed on the inner wall of the fixing ring at equal intervals, lower outer fixing buckles are installed on the inner wall of the fixing ring below the upper outer fixing buckles, and the lower outer fixing buckles are connected with the annular frame. A fixing ring is arranged on the upper portion of the fixing base, a girdling fixator is arranged in the fixing ring, a plurality of upper inner fixing buckles are installed on the outer wall of the girdling fixator at equal intervals, lower inner fixing buckles are installed on the portions, below the upper inner fixing buckles, of the outer wall of the girdling fixator, and an upper elastic rope is arranged on the outer portion of the girdling fixator. According to the utility model, not only are convenient all-directional elastic support and fixation of a user and convenient height adjustment and adaptation of the user realized, but also circumferential rotation and reversing are convenient to carry out multi-position fixation and displacement prevention during use, and the flexibility and the stability of use are improved.

The automatic feeding numerical control lathe comprises a machine shell, a material box is fixed in the machine shell, evenly-distributed bars are arranged in the material box, an inclined plate is arranged on the inner wall of one side of the material box, an arc bottom is arranged at the bottom of the material box and matched with the bars, and a second cylinder body is fixed to one side of the bottom of the material box; a second sliding rod is movably inserted into the second cylinder body, a first cylinder body is fixed to the outer wall of one side of the material box, a first sliding rod is movably inserted into the first cylinder body, and pistons are fixed to one end of the first sliding rod and one end of the second sliding rod. A first sliding rod is extruded through a connecting arm of the manipulator, so that a second sliding rod can automatically push out bars in a material box, then the manipulator can clamp the extending bars and then automatically load the bars into a chuck, the bars do not need to be manually loaded into the chuck, and the working efficiency is improved. And therefore, the numerical control lathe is more convenient to turn the bar.

The present application relates to the field of medical devices, and provides an ablation catheter and an ablation system comprising the same, the ablation catheter comprising a penetrating part, an ablation main body, a catheter main body and a control handle connected in sequence; the penetrating part comprises a screwing-in member capable of screwing into and being fixed to a target tissue under the action of an external force; the ablation main body comprises an ablation electrode, a connecting member and a temperature sensor; the catheter main body comprises a non-ablation electrode and a perfusion channel; the non-ablation electrode is arranged in a spaced manner with the ablation electrode, and the non-ablation electrode is not in contact with the target tissue during ablation. By using the ablation catheter and the ablation system, the thickened interventricular septum is screwed and ablated, the screwing speed is easier to control, the depth can be stopped or adjusted in time before penetrating the myocardial wall, myocardial perforation can be prevented, and the damage to the myocardial tissue is reduced through temperature detection and perfusion function.
