DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] This specific embodiment is a screw processing machine, and its structural schematic diagram is as follows Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5As shown, the workbench 1 comprises a workbench 1, a vertical plate 11 is installed on the side of the workbench 1, a motor 17 is installed on the side of the vertical plate 11, the motor 17 is connected to a connecting rod 15, the connecting rod 15 is connected to a connecting assembly 2, slide plates 10 are installed on both sides of the vertical plate 11, the slide plates 10 are provided with a slide groove 13, the slide groove 13 is slidably connected to a slider 9, the slider 9 is connected to a push plate 6, through holes 12 are provided at the vertical plate 11, the slide plate 10 and the push plate 6 on the upper surface of the workbench 1, a box body 3 is installed at the lower part of the workbench 1, a drawer 16 is movably connected to the side of the box body 3, and a drawer 16 is movably connected to the push plate 6. A circular hole 8 is provided at the center position, a second cylinder 14 is fixedly passed through the upper part of the push plate 6, a clamping plate 21 is connected to the lower end of the second cylinder 14, a plurality of groups of evenly distributed clamping teeth 20 are provided on the lower surface of the clamping plate 21, the clamping plate 21 is in the circular hole 8, a fixing plate 7 is installed at the lower part of the side of the push plate 6, the lowest part of the fixing plate 7 is adapted to the lowest part of the circular hole 8, a card slot 18 is provided on the fixing plate 7, a butt plate 19 is installed on the end of the upper surface of the fixing plate 7 away from the push plate 6, the butt plate 19 is adjacent to the card slot 18, a first cylinder 5 is connected to the lower part of the push plate 6, and the first cylinder 5 is connected to the side The plate 4 and the side plate 4 are fixedly mounted on the upper surface of the workbench 1. When the tapping machine is used to open the internal thread of the internal and external thread screws, the screw is placed at the circular hole 8, wherein the screw head is placed in the card slot 18. When the screw head is placed in the card slot 18, its head contacts the abutment plate 19. The abutment plate 19 provides a limit for the screw to prevent the screw from moving when the internal thread is opened. Then the second cylinder 14 is started, and the second cylinder 14 drives the clamping plate 21 to move downward. The clamping plate 21 moves downward and drives the clamping teeth 20 to abut against the screw to complete the fixing of the screw. Then the second cylinder 14 is started. The motor 17 drives the connecting rod 15 to rotate, and the rotation of the connecting rod 15 drives the tap 207 to rotate. When the motor 17 is started, the first cylinder 5 is started synchronously, and the first cylinder 5 starts to drive the push plate 6 to move horizontally. The push plate 6 moves horizontally and drives the slider 9 to slide horizontally along the slide groove 13. The push plate 6 moves horizontally and drives the fixed plate 7 to move horizontally. The fixed plate 7 moves horizontally and drives the abutment plate 19 and the screw to move horizontally. The screw moves horizontally and contacts with the tap 207, completing the opening of the internal thread on the screw, and the iron filings generated by tapping fall from the through hole 12 into the drawer 16.

[0030] Reference Figure 1 , Figure 3 , Figure 6As shown, the connecting assembly 2 includes a connecting seat 201, which is fixedly connected to the connecting rod 15. The connecting seat 201 is provided with a limiting groove 206, and the limiting groove 206 is slidably engaged with a clamping block 203. Both ends of the clamping block 203 are provided with symmetrically distributed limiting blocks 202, and the limiting blocks 202 are installed with taps 207. Threaded holes 205 are provided on the connecting seat 201 and the clamping block 203. The threaded holes 205 are threadedly adapted with bolts 204. The tap 207 needs to be replaced accordingly. A tool is used to release the fixing of the clamping block 203 by the bolts 204, and then the clamping block 203 and the tap 207 are taken out, and a new tap 207 is replaced, and the clamping block 203 is aligned with the limiting groove 206 and clamped, and then the bolts 204 are used to connect the clamping block 203 and the connecting seat 201 to complete the replacement.

[0031] Working principle: when using a tapping machine to open internal threads for internal and external thread screws (tapping is to use a certain torque to screw the tap 207 into the bottom hole to be drilled to process the internal threads), place the screw in the round hole 8, and place the screw head into the slot 18. When the screw head is placed in the slot 18, its head contacts the abutment plate 19. The abutment plate 19 provides a limit for the screw to prevent the screw from moving when the internal thread is opened. Then start the second cylinder 14, and the second cylinder 14 drives the clamping plate 21 to move downward. The downward movement of the clamping plate 21 drives the clamping teeth 20 to abut against the screw to complete the fixation of the screw. Then start the motor 17 to drive the connecting rod 15 to rotate, and the rotation of the connecting rod 15 drives the tap 207 to rotate. When starting the motor 17, the first cylinder 5 is started synchronously. The start of the first cylinder 5 drives the push plate 6 to move horizontally, and the horizontal movement of the push plate 6 drives the sliding The block 9 slides horizontally along the slide groove 13, the push plate 6 moves horizontally to drive the fixed plate 7 to move horizontally, the fixed plate 7 moves horizontally to drive the abutment plate 19 and the screw to move horizontally, the screw moves horizontally and contacts the tap 207, and the internal thread of the screw is completed (different screws correspond to different taps 207, and the center position of the same screw does not change after being fixed, that is, the distance between the center position and the lowest point of the circular hole 8 is certain, and the matching tap 207 is used to ensure that the center point of the tap 207 is adapted to the center position of the screw, so that there is no need to adjust the tap 207 to adapt to the center point of the screw), the iron filings generated by tapping fall from the through hole 12 into the drawer 16, and the mechanical components are installed in the place where the iron filings cannot fall through the arrangement of the through hole 12, the vertical plate 11, and the push plate 6, so as to avoid the iron filings affecting the normal use of the mechanical components.

[0032] When the screw needs to be replaced, the tap 207 needs to be replaced accordingly. Use a tool to release the bolt 204 from fixing the block 203, then take out the block 203 and the tap 207, replace the new tap 207, align the block 203 with the limiting groove 206 and insert it, then use the bolt 204 to connect the block 203 and the connecting seat 201 to complete the replacement. Through the setting of the connecting component 2, the tap 207 can be flexibly replaced, which is convenient for changing the tap 207 according to the different internal threads of the screws, thereby improving the practicality of the device.

[0033] Finally, it should be noted that the above is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present utility model shall be included in the protection scope of the present utility model.
