A workbench, a fixed frame and a processing frame are set up, and the screw blank is clamped and fixed by the fixed plate and the clamping plate on the fixed frame. Then the processing frame is driven by the drag chain to move close to the fixed frame, and the processing milling cutter is attached to the screw blank. At the same time, the reduction motor in the fixed frame drives the screw blank to rotate for cutting processing. This solves the problem that the traditional milling cutter needs to be manually pushed close to the blank, which has a high risk factor and is easy to cause injury to human personnel. It cannot be automatically milled, and a large amount of debris will be generated during milling. A large amount of metal debris will gather on the surface of the workbench. These debris will splash around, affecting the surrounding environment, and the subsequent cleaning is very cumbersome.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0023] Reference Figures 1-4 A kind of anti-falling screw processing equipment, including mounting ring seat 1, fixed base 11 is installed in the top middle part of mounting ring seat 1, clamping groove 111 is opened in the top middle part of fixed base 11, limit sliding groove is opened in the four around of fixed base 11 in clamping groove 111, limit sliding block 2 is slidably arranged in limit sliding groove, the top of limit sliding block 2 is connected with fixed block and is connected with clamping block 21 by penetrating fixed base 11 on the side close to clamping groove 111;

[0024] And, limit sliding block 2 is clamped with limit assembly 3 on the side away from clamping groove 111, and fixed recess 114 is opened in the two sides of limit sliding groove in fixed base 11 symmetrically, and a plurality of clamping assemblies 4 are installed at equal distances in fixed recess 114.

[0025] Meanwhile, clamping assembly 4 includes movable plate 42, fixed shaft 41 is arranged through one side in movable plate 42, both ends of fixed shaft 41 are fixedly connected with the inner wall of fixed recess 114, and movable plate 42 is eccentrically installed.

[0026] Meanwhile, spring 43 is installed on the side of fixed recess 114 and the longer side of corresponding movable plate 42 on the side of fixed shaft 41, one side of spring 43 is connected with movable plate 42, and the other side of spring 43 is connected with fixed recess 114.

[0027] Further, limit assembly 3 includes fixed rod 31, T-shaped fixed block 32 is fixedly installed on one side of fixed rod 31, and handle part is connected with fixed base 11 by penetrating fixed rod 31 on the other side.

[0028] And, clamping protrusion 33 is installed on both ends of the side close to T-shaped fixed block 32 of fixed rod 31, and clamping cavity is opened in limit sliding block 2 at T-shaped fixed block 32.

[0029] Furthermore, an arc-shaped groove is provided on one side of the clamping block 21 close to the clamping groove 111, and a rubber pad is provided on the inner wall of the arc-shaped groove. The rubber pad can increase the friction between the clamping surface and the screw, preventing the screw from sliding or rotating during the clamping process, thereby improving the stability of the screw clamping and reducing the direct friction and damage of the clamping block to the screw surface.

[0030] Furthermore, auxiliary slots 112 are provided above and below the limiting slot in the fixed base 11. The length of the auxiliary slots 112 is consistent with the length of the fixed groove 114. A movable cavity 113 is provided outside the limiting slot in the fixed base 11 and on the longer side of the movable plate. The diameter of the movable cavity 113 is greater than the diameter of the fixing rod 31 plus the length of the two clamping protrusions 33.

[0031] Furthermore, it is worth noting that the longer side of the movable plate 42 is located on the side close to the locking groove 111 .

[0032] In this embodiment, by configuring multiple limit components 3, limit sliders 2, clamping blocks 21 and multiple clamping components 4, screws within a certain range can be limited, clamped and fixed. At the same time, the four clamping block components are arranged in a ring shape. When clamping the screws, the clamping blocks 21 are evenly distributed around the screws, forming a stable clamping force, improving the stability of the screw clamping, and the entire operation process is convenient.

[0033] By placing one end of the screw in the locking groove 111, and then pushing the handle portion 34 into the fixed base 11, the limiting slider 2 and the corresponding clamping block 21 move toward the outer wall of the screw until the rubber pad layer of the arc-shaped groove of the clamping block 21 fits with the outer wall of the screw, and during the movement, the locking protrusion 33 slides in the corresponding fixing groove 114 and is limited by the action of the locking component 4. When the locking protrusion 33 moves toward the locking groove 111, the locking It is assumed that the protrusion 33 presses the movable plate 42, and the movable plate 42 moves into the fixed groove 114, and its spring is in a compressed state at this time. When the locking protrusion 33 leaves the movable plate 42, the spring 43 returns to its original state under its own action. When the spring 43 is in the original state, the longer side of the movable plate 42 is higher than the shorter side of the movable plate 42, so that the locking protrusion 33 is limited by the longer side of the movable plate 42, preventing the locking protrusion 33 from moving to the side away from the locking groove 111.

[0034] When there is no need to clamp the screw, the clamping protrusion 33 is pushed to the nearest active cavity and rotated in the active cavity until the clamping protrusion 33 is rotated to be located in the auxiliary slide groove 112 and moved along the auxiliary slide groove 112, thereby moving the clamping block 21 away from the outer wall of the screw, losing the clamping of the screw, and the entire operation process is convenient.

[0035] In the present invention, through the arrangement of multiple limit components 3, limit sliders 2, clamping blocks 21 and multiple clamping components 4, screws within a certain range can be limited, clamped and fixed. At the same time, the four clamping block components are arranged in a ring shape. When clamping the screws, the clamping blocks 21 are evenly distributed around the screws, forming a stable clamping force, improving the stability of the screw clamping, and the entire operation process is convenient.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
