The application relates to the technical field of thread rolling machines, and particularly discloses a high-efficiency thread rolling machine which comprises a base and a mounting rack mounted on the base, a bearing frame is arranged on the mounting rack, a plurality of workpieces are mounted in the bearing frame, a conveying frame is slidably connected in the base, a power mechanism for driving the conveying frame to slide is arranged on the base, and a thread rolling assembly is further arranged on the side of the base away from the mounting rack. The automatic feeding, clamping and fixing and conveying integration operation of the workpieces can be realized, the time interval from the fixing to the thread rolling of the workpieces is effectively shortened, and the machining efficiency is improved. In the sliding stroke of the conveying frame, the clamping mechanism and the guide groove on the side plate are utilized to automatically clamp and fix the workpieces in the process that the conveying frame moves towards the thread rolling assembly, and the structure is compact and the action is reliable.

This invention belongs to the field of foundation filling, specifically an auxiliary device and its operating method for vibratory compaction of crushed stone piles. It includes a vehicle body, a fixed frame fixedly connected to one side of the vehicle body, a first motor fixedly connected to the bottom of the fixed frame, and an output end of the first motor extending into the interior of the fixed frame and fixedly connected to a lead screw. The lead screw is rotatably connected to the fixed frame, and a connecting block is connected to the outer wall of the lead screw via a lead screw nut pair. The connecting block is slidably connected to the fixed frame. This invention provides an auxiliary device and its operating method for vibratory compaction of crushed stone piles. The first motor controls the sleeve to intermittently compress downwards, which, in conjunction with the bottom of the partition, compacts the crushed stone entering the vibratory compaction hole. A compression ring further encloses the crushed stone entering the vibratory compaction hole. As the sleeve moves downwards, the concave surface formed by the discharge chute and the partition allows the crushed stone to concentrate inwards and accumulate upwards in a pagoda-like shape, preventing excessive compression of the hole wall and thus avoiding collapse of the hole wall.

The utility model belongs to cutting equipment technical field especially relates to a cutting equipment of granite, including receiving material box, the side of receiving material box is provided with side support, is provided with rotary drive mechanism above side support, receiving material box one end is provided with end support, the end away from end support of receiving material box is opened as open mouth and is provided with has the slot above the open mouth, is provided with pull -out board in the slot, is opened as open mouth in receiving material box top, is provided with bearing seat symmetrically above receiving material box, is provided with rotating shaft in bearing seat and rotating shaft is close to rotary drive mechanism one end of setting up rotating wheel, rotating wheel is connected with rotary drive mechanism rotation through belt, is provided with saw blade on rotating shaft, is provided with sliding mechanism above receiving material box, is provided with L shape's load plate above sliding mechanism. The utility model has solved the problem of dirty and disorderly environment in the work site, eliminated the security risk brought by wet and slippery, also through the mixture of mud and water convenient to collect, created favorable conditions for subsequent water resource recovery or solid waste treatment.

The utility model discloses a kind of inner snap spring mounting devices of motor output shaft, comprising: rack;Mounting plate, vertically mobilely be set on rack;Lifting drive mechanism, with mounting plate drive connection;Fixing mechanism;Inner snap spring feeding mechanism;Feeding channel, be below inner snap spring feeding mechanism, its thickness is configured to allow single-layer inner snap spring pass and limit multiple-layer inner snap spring pass simultaneously;Pushing mechanism, including the pushing piece of being able to extend into feeding channel;Guide channel, with the discharge end of feeding channel intercommunication, its inner wall is big taper of small from top to bottom;Pressing mechanism, including being located in the pressing head of guide channel just above and the pressing drive mechanism of driving pressing head along guide channel axial motion, pressing head is used to be located in the inner snap spring of guide channel along guide channel downward pressure and send. Advantage is: the present scheme will inner snap spring installation from "artificial experience dependence" upgrade "precise mechanical execution", realize overall breakthrough in efficiency, accuracy, cost, security and other dimensions.

The utility model discloses a cup lid stacking and conveying mechanism, and relates to the technical field of cup lid conveying devices, the cup lid stacking and conveying mechanism comprises a conveyor, the outer wall of the bottom of the conveyor is fixedly connected with a plurality of limiting rods, the outer walls of the limiting rods are slidably connected with a supporting plate, and the outer wall of the bottom of the supporting plate is fixedly connected with a gravity sensor. Due to the fact that the convex sliding blocks are arranged on the concave sliding rails, when equipment needs to be used, the electric telescopic rods can move to drive the push plates to move, due to the fact that the positions of the connecting rods are limited by the limiting shafts, the push plates can be driven to move, and the push plates can be driven to move by the electric telescopic rods. And the other end of the connecting rod is fixed by the limiting shaft II, so that the sliding block is driven to slide on the push plate when the push plate moves, and then the limiting shaft II is driven to move, so that a user can freely adjust the distance between the stacking frames according to the diameter of the cup cover, and the cup covers with different sizes can be conveniently stacked.
