Description

Technical Field

[0001] This utility model relates to the technical field of nut processing equipment, specifically a tapping machine for nut processing. Background Technology

[0002] A tapping machine is needed in the nut machining process. A tapping machine is a machining device that processes internal threads, screws, or threads on the inner surface of holes in various parts such as machine housings, equipment end faces, nuts, and flanges, using either through holes or blind holes of different specifications. Tapping machines are also called thread tapping machines, automatic tapping machines, etc., and are further divided into drilling tapping machines and reaming tapping machines.

[0003] A prior art tapping machine for nut processing, with application number 202421454986.5, includes a base plate. This tapping machine, through the extension of a second electric telescopic rod, moves a positioning pin above a receiving box. The operator can then place the nut to be processed onto the surface of the positioning pin, thus positioning the nut during placement and ensuring it is below the tapping mechanism, improving tapping efficiency and the quality of the finished nut. During the tapping process, the second electric telescopic rod retracts, causing the positioning pin to disengage from the nut, improving stability during tapping. However, this method is inconvenient for unloading, as unloading is time-consuming and labor-intensive, thus affecting tapping efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a tapping machine for nut processing, so as to solve the problem that the existing technology is inconvenient for unloading, and the unloading is time-consuming and laborious, thus affecting the efficiency of tapping processing.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a tapping machine for nut processing, comprising a base, a hydraulic cylinder mounted on the upper side of the base via an upper bracket, a lifting plate mounted on the lower end of the hydraulic cylinder, and a tapping head mounted on the lower center of the lifting plate via a tapping motor and a connecting seat; a fixed clamping seat mounted on the upper side of one end of the base, and a movable clamping seat mounted on the other upper side of the base via a second hydraulic cylinder and a transverse support; a nut positioning groove mounted on the middle of one side of both the fixed clamping seat and the movable clamping seat, and slag discharge holes mounted on the upper and lower walls of the nut positioning groove; a first unloading hole mounted inside the movable clamping seat; a first unloading rod fixedly mounted on the side wall of the upper bracket and transversely inserted into the first unloading hole; a second unloading hole mounted on the side wall of the nut positioning groove of the fixed clamping seat, and a second unloading rod transversely inserted into the second unloading hole; and an unloading bracket mounted on one side of the fixed clamping seat that cooperates with the transverse support for transverse movement.

[0006] Furthermore, half of the slag discharge hole is configured as a semi-circular hole, and the single nut positioning groove is configured as a semi-hexagonal prism groove.

[0007] Furthermore, a slag discharge trough is provided on the base below the slag discharge hole, and one end of the slag discharge trough is inclined downward.

[0008] Furthermore, the transverse support is configured as a U-shaped support, and the transverse support is laterally slidable with the side wall of the upper support.

[0009] Furthermore, a limiting seat is provided on one side of the fixed clamp, which is laterally slidably arranged with the unloading bracket. The unloading bracket is configured as a right-angle Z-shaped bracket, and the straight edges at both ends of the unloading bracket are vertically arranged.

[0010] Furthermore, a return spring is sleeved on the outer side of one end of the second unloading rod, and a limiting plate is also provided on one end of the second unloading rod.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] This utility model has a fixed clamp and a movable clamp on the upper side of one end of the base. The nut blank is inserted laterally into the half-nut positioning groove on one side of the fixed clamp. Then, the movable clamp is driven by the second hydraulic cylinder to move to the side of the fixed clamp to clamp and fix the nut blank laterally. Moreover, the clamping and fixing stability is high, which is beneficial to improving the tapping accuracy of the nut.

[0013] This invention features a first unloading hole within a movable clamp, and a first unloading rod fixed to the side wall of an upper support, which is laterally inserted into the first unloading hole. This allows the second hydraulic cylinder to drive the transverse support and movable clamp to move away from the fixed clamp. Since the first unloading rod is welded to the inner side of the upper support, it can push the nut remaining in the movable clamp out of its nut positioning groove, facilitating the unloading of the processed nut. Furthermore, the fixed clamp has a first unloading hole on its nut positioning groove side wall, with the first unloading rod laterally inserted into it. A unloading bracket, which cooperates with the transverse support's lateral movement, is located on one side of the fixed clamp. When the second hydraulic cylinder drives the transverse support and movable clamp to move away from the fixed clamp and reset, one end of the transverse support hooks onto the unloading bracket and moves laterally, while the other end of the unloading bracket presses against the second unloading rod, pushing the nut remaining in the fixed clamp out of its nut positioning groove. This achieves unloading from both clamps, making unloading convenient and quick. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1 , Figure 2 , Figure 3 In this embodiment of the utility model, a tapping machine for nut processing includes a base 1. A first hydraulic cylinder 3 is provided on the upper side of the base 1 via an upper bracket 2. A lifting plate 4 is provided at the lower end of the first hydraulic cylinder 3. A tapping head 11 is provided in the middle of the lower side of the lifting plate 4 via a tapping motor 12 and a connecting seat. A fixed clamping seat 5 is also provided on the upper side of one end of the base 1. A movable clamping seat 6 is also provided on the other upper side of the base 1 via a second hydraulic cylinder 7 and a transverse support 8. The transverse support 8 is configured as a U-shaped support and is laterally slidably arranged with the side wall of the upper bracket 2. A nut positioning groove 15 is provided in the middle of one side of both the fixed clamping seat 5 and the movable clamping seat 6. A half slag discharge hole 13 is configured as a semi-circular hole, and a single nut positioning groove 15 is configured as a semi-hexagonal prism groove. The movable clamping seat 6 is driven by the second hydraulic cylinder 7 to move towards the fixed clamping seat 5 to laterally clamp and fix the nut blank, preventing the nut from moving during processing, which is beneficial to improving the tapping accuracy.

[0021] like Figure 1 and Figure 2 As shown, in order to discharge slag downwards, slag discharge holes 13 are provided on both the upper and lower walls of the nut positioning groove 15. A slag discharge trough 21 is provided on the base 1 below the slag discharge hole 13, and one end of the slag discharge trough 21 is inclined downwards to facilitate downward slag discharge.

[0022] like Figure 1 and Figure 3As shown, in order to unload the movable clamp 6, a first unloading hole 17 is provided in the movable clamp 6. A first unloading rod 9 is fixedly provided on the side wall of the upper bracket 2 and is horizontally inserted into the first unloading hole 17. This allows the second hydraulic cylinder 7 to drive the transverse support 8 and the movable clamp 6 to move away from the fixed clamp 5. Since the first unloading rod 9 is fixedly welded to the inside of the upper bracket 2, it can push the nut remaining in the movable clamp 6 out of its nut positioning groove 15, which is convenient for unloading the processed nut.

[0023] like Figure 1 and Figure 3 As shown, in order to unload the fixed clamp 5, a second unloading hole 18 is provided on the side wall of the nut positioning groove 15 of the fixed clamp 5, and a second unloading rod 16 is inserted into the second unloading hole 18 laterally. A return spring 20 is sleeved on the outer side of one end of the second unloading rod 16, and a limiting plate 19 is also provided on one end of the second unloading rod 16. An unloading bracket 10 is provided on one side of the fixed clamp 5 to cooperate with the transverse moving bracket 8 for transverse movement. A limiting seat 14 is also provided on one side of the fixed clamp 5 to slide laterally with the unloading bracket 10. The unloading bracket 10 is set as a right-angle Z-shaped bracket, and the straight edges of the two ends of the unloading bracket 10 are set vertically. When the transverse moving bracket 8 and the movable clamp 6 are driven by the second hydraulic cylinder 7 to move and reset away from the fixed clamp 5, one end of the transverse moving bracket 8 hooks the unloading bracket 10 and moves laterally, and the other end of the unloading bracket 10 squeezes the second unloading rod 16 to push the nut remaining in the fixed clamp 5 out of its nut positioning groove 15, thereby realizing the unloading process of the fixed clamp 5. The unloading is convenient and quick.

[0024] The working principle and usage process of this utility model are as follows: When in use, the nut blank is inserted horizontally into the half-nut positioning groove 15 on one side of the fixed clamp 5. Then, the movable clamp 6 is driven by the second hydraulic cylinder 7 to move to the side of the fixed clamp 5 to clamp and fix the nut blank horizontally. Then, the lifting plate 4 and the tapping motor 12 are driven by the first hydraulic cylinder 3 to move downward. The rotating tapping head 11 is used to tap the nut blank. After tapping is completed, the tapping motor 12 drives the tapping head 11 to rotate in the opposite direction to push out the nut. The clamp is used for limiting, so that the tapped nut can be removed from the tapping head 11, thus completing a single processing.

[0025] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
