DETAILED DESCRIPTION

[0023] In order to have a clearer understanding of the technical features, purposes and effects of the utility model, the specific implementation mode of the utility model will be described with reference to the drawings.

[0024] Embodiment 1: the preferred embodiment of the electric screw press hole expanding device provided by the utility model as shown in the figure Figures 1 to 6 An electric screw press hole expanding device, which comprises a machining rack 1;

[0025] The electric screw press body 2 is fixedly installed inside the machining rack 1;

[0026] The outer wall of the electric screw press body 2 is rotationally connected with the limiting frame 3;

[0027] The machining assembly 4 is arranged below the electric screw press body 2, and the machining assembly 4 comprises a reaming assembly 41 arranged below the electric screw press body 2. The reaming assembly 41 comprises a telescopic rod 411 fixedly installed at the bottom end of the electric screw press body 2. The outer wall of the telescopic rod 411 is fixedly installed with a fixed block 412. The outer wall of the fixed block 412 is fixedly installed with a sleeve 413. The inside of the sleeve 413 is slidably provided with a limiting block 414. The side wall of the limiting block 414 is fixedly installed with a sliding rod 415. The end of the sliding rod 415 away from the limiting block 414 is fixedly installed with a reaming plate 416. The outer wall of the reaming plate 416 is fixedly installed with an inclined frame 417. The inside of the inclined frame 417 is slidably provided with a sliding column 418. The end of the sliding column 418 is fixedly installed with a connecting frame 419. The end of the connecting frame 419 is fixedly installed with a movable block 420.

[0028] In this embodiment, when the workpiece needs to be reamed, it is clamped and fixed in the machining rack 1 through the fixing assembly 43. At this time, the electric screw press body 2 is started, and the end-fixed telescopic rod 411 is rotated and pushed downward, so that the outer wall of the reaming plate 416 is in contact with the inner hole of the workpiece. With the restriction of the downward and rotating reaming plate 416, the workpiece can be reamed. When the original hole of the workpiece is small, the position of the reaming plate 416 needs to be adjusted. At this time, the telescopic rod 411 is started, which pulls the movable block 420 to the fixed block 412. The outer wall of the movable block 420 is fixedly installed with the connecting frame 419, which drives the sliding column 418 to move. Since the inclined frame 417 is inclined, and the sliding column 418 is slidably arranged in the inside of the inclined frame 417, under the restriction thereof, the inclined frame 417 drives the sliding rod 415 fixedly installed on the outer wall of the reaming plate 416 to slide into the inside of the sleeve 413. The six reaming plates 416 move in a converging manner to adjust their diameters, so as to facilitate the setting of the workpiece with a smaller hole diameter. When the telescopic rod 411 pushes the movable block 420 away from the fixed block 412, the reaming plate 416 moves in an opening manner, so as to quickly contact the reaming plate 416 and improve the reaming efficiency.

[0029] Further, the end of the telescopic rod 411 away from the electric screw press body 2 is fixedly installed with the movable block 420. The outer wall of the reaming plate 416 is arranged in an arc surface. When the telescopic rod 411 pushes the movable block 420 downward, the reaming plate 416 moves in an opening manner to quickly contact the inner wall of the hole of the workpiece.

[0030] Further, the inclined frame 417 is arranged in an inclined manner. The outer wall of the limiting block 414 is slidably arranged in the inside of the sleeve 413. Under the sliding restriction of the limiting block 414 and the sliding rod 415 and the sleeve 413, when the sliding column 418 is extruded in the inside of the inclined frame 417, the six groups of reaming plates 416 can stably move.

[0031] The preferable embodiment of the reaming device for the electric screw press provided by the utility model based on example 1 is as follows Figures 1 to 6 As shown in the figure: the fixed assembly 43 comprises a limiting rod 431 fixedly installed inside the machining rack 1, a sleeve ring 432 slidingly arranged on the outer wall of the limiting rod 431, a moving plate 433 fixedly installed on the outer wall of the sleeve ring 432, a sleeve frame 434 slidingly arranged on the outer wall of the moving plate 433, a pressing plate 435 fixedly installed on the outer wall of the sleeve frame 434, and a screw rod 436 sleeved inside the moving plate 433.

[0032] In this embodiment, when the workpiece needs to be reamed, it is placed below the pressing plate 435, and the screw rod 436 is rotated. Since the sleeve ring 432 fixedly installed at the end of the moving plate 433 is slidingly arranged on the limiting rod 431, under the limitation thereof, the rotating screw rod 436 drives the moving plate 433 sleeved on the outer wall thereof to move downward, and the moving plate 433 drives the sleeve frame 434 and the pressing plate 435 sleeved on the outer wall thereof to move downward, so that the pressing plate 435 is pressed and fixed to the workpiece. When the size of the workpiece is small, the sleeve frame 434 is slid, so that it slides on the outer wall of the moving plate 433, and the position interval of the two pressing plates 435 is adjusted, so as to press and fix workpieces of different sizes. The structure can quickly fix the workpiece for reaming.

[0033] Furthermore, the number of the pressing plates 435 is two, which are distributed in parallel inside the machining rack 1, and under the pressing limitation of the two groups of pressing plates 435, the reaming plate 416 can stably ream the workpiece.

[0034] In addition, the end of the screw rod 436 is rotationally connected to the inside of the machining rack 1, and the outer wall of the screw rod 436 is threadedly sleeved inside the moving plate 433. Under the sliding limitation of the sleeve ring 432 and the limiting rod 431, the rotating screw rod 436 can drive the moving plate 433 to stably move downward, so that the pressing plate 435 can be pressed.

[0035] The above is only a specific embodiment of the utility model, and is not used to limit the scope of the utility model. Any person skilled in the art can make equivalent changes and modifications without departing from the concept and principles of the utility model, and the changes and modifications shall belong to the protection scope of the utility model.
