[0002] The chip-breaking alloy straight-flute drill is a type of alloy drill bit. The chip-breaking alloy straight-flute drill adopts an internal hole cooling method, which greatly improves its chip-breaking and chip evacuation performance during drilling. The chip-breaking alloy straight-flute drill has excellent self-centering ability, can be processed efficiently, and the machining accuracy of the holes processed can reach H7. The chip-breaking alloy straight-flute drill is widely used in the hole machining of various materials. When producing the chip-breaking alloy straight-flute drill, a fixture tooling is required to clamp and fix the chip-breaking alloy straight-flute drill, which can ensure that the chip-breaking alloy straight-flute drill will not shift or fall off during processing.

[0003] In the related art, although the fixture tooling for the production of chip-breaking alloy straight-flute drills can meet the basic requirements of clamping and fixing the chip-breaking alloy straight-flute drill, it is found that there are still at least the following deficiencies in actual operation: The fixture tooling for the production of chip-breaking alloy straight-flute drills can only clamp and fix one chip-breaking alloy straight-flute drill at a time. After the clamped chip-breaking alloy straight-flute drill is processed, it needs to be disassembled and removed before the next chip-breaking alloy straight-flute drill can be clamped and fixed for continued processing. When processing a large number of chip-breaking alloy straight-flute drills in sequence, the operation steps of clamping and fixing and disassembling and removing the chip-breaking alloy straight-flute drill need to be repeated several times. This operation process is relatively cumbersome, consumes a lot of working time, and has a relatively low working efficiency.

[0004] Therefore, we propose a fixture tooling for the production of chip-breaking alloy straight-flute drills to solve the above problems. Utility Model Content

[0023] The technical solutions of the present application will be clearly and completely described below in conjunction with specific embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present application without creative efforts shall fall within the scope of protection of the present application.

[0024] See Figure 1 、 Figure 2 and Figure 3 ,the present application provides a fixture tooling for the production of chip-breaking alloy straight-flute drills, including a U-shaped frame 1, a lower chuck 4 and an upper chuck 8, wherein:

[0025] A first shaft seat 2 is fixedly installed on the inner wall of the bottom of the U-shaped frame 1. A column 3 is rotatably installed on the top of the first shaft seat 2. The lower chuck 4 is fixedly installed at the top of the column 3. A plurality of lower arc-shaped clamping grooves 5 are formed on the top edge of the lower chuck 4. The plurality of lower arc-shaped clamping grooves 5 are distributed in an equidistant annular manner. An electric hydraulic cylinder 6 is fixedly installed on the inner wall of the top of the U-shaped frame 1. A second shaft seat 7 is rotatably installed at the output shaft end of the electric hydraulic cylinder 6. The upper chuck 8 is fixedly installed at the bottom of the second shaft seat 7. The upper chuck 8 is located directly above the lower chuck 4. By utilizing the retractable feature of the electric hydraulic cylinder 6, the vertical lifting of the second shaft seat 7 and the upper chuck 8 can be controlled. The diameter sizes of the lower chuck 4 and the upper chuck 8 are set to be the same. A plurality of upper arc-shaped clamping grooves 9 are formed on the bottom edge of the upper chuck 8. The plurality of upper arc-shaped clamping grooves 9 are distributed in an equidistant annular manner, and the plurality of upper arc-shaped clamping grooves 9 are respectively located directly above the corresponding lower arc-shaped clamping grooves 5. By the combined action of the upper arc-shaped clamping grooves 9 and the lower arc-shaped clamping grooves 5 directly below them, one end of the chip-breaking alloy straight-flute drill can be clamped and fixed. By providing a plurality of upper arc-shaped clamping grooves 9 and a plurality of lower arc-shaped clamping grooves 5, a plurality of chip-breaking alloy straight-flute drills can be clamped and fixed simultaneously. A connecting column 12 is fixedly installed at the center of the bottom of the upper chuck 8. A jack 13 is formed at the center of the top of the lower chuck 4. A slot 14 communicating with the jack 13 is formed at the top of the column 3. The bottom end of the connecting column 12 slides through the jack 13 and is slidably installed in the slot 14. The cross-sections of the connecting column 12, the jack 13 and the slot 14 are all rectangular, which can ensure that the lower chuck 4 and the upper chuck 8 can rotate synchronously. A driving mechanism for controlling the rotation of the column 3 is provided on the U-shaped frame 1, that is, the synchronous rotation of the lower chuck 4 and the upper chuck 8 can be controlled, so as to facilitate the horizontal rotation adjustment of the clamped and fixed plurality of chip-breaking alloy straight-flute drills and facilitate the processing of the chip-breaking alloy straight-flute drills one by one.

[0026] In this embodiment, in order to prevent damage to the clamping parts of the chip-breaking alloy straight-flute drills, lower protective pads 10 are fixedly installed on the inner walls at the bottoms of the multiple lower arc-shaped clamping grooves 5, and upper protective pads 11 are fixedly installed on the inner walls at the tops of the multiple upper arc-shaped clamping grooves 9. It should be noted that both the lower protective pads 10 and the upper protective pads 11 are made of rubber materials with good wear resistance.

[0027] In this embodiment, a support ring 15 is arranged inside the U-shaped frame 1. The top of the lower chuck 4 penetrates through the inner ring of the support ring 15. Cross beams 16 are fixedly installed on both sides at the bottom end of the connecting column 12. Avoidance holes 17 are formed on the inner walls on both sides of the slot 14. One end of each of the two cross beams 16 away from each other penetrates through the corresponding avoidance holes 17 respectively. Vertical beams 18 are fixedly installed on both sides at the bottom of the support ring 15. The bottom ends of the two vertical beams 18 are fixedly connected to one end of each of the two cross beams 16 away from each other. When one ends of multiple chip-breaking alloy straight-flute drills are sequentially placed in the corresponding lower arc-shaped clamping grooves 5, the support ring 15 can be used to support the multiple chip-breaking alloy straight-flute drills, so as to facilitate subsequent simultaneous clamping and fixing of the multiple chip-breaking alloy straight-flute drills. By moving the connecting column 12 downward, the support ring 15 can be driven to move downward through the two cross beams 16 and the two vertical beams 18. Furthermore, when clamping and fixing the multiple chip-breaking alloy straight-flute drills, there is a certain distance between the support ring 15 and the chip-breaking alloy straight-flute drills, which will not affect the processing operation of the chip-breaking alloy straight-flute drills.

[0028] In this embodiment, in order to ensure that the support ring 15 can move vertically smoothly, the inner ring diameter of the support ring 15 is larger than the diameter of the lower chuck 4.

[0029] In this embodiment, in order to ensure the effective support of the support ring 15 for multiple chip-breaking alloy straight-flute drills, the middle part of the upper surface of the support ring 15 is flush with the upper surface of the lower protective pad 10.

[0030] In this embodiment, the above-mentioned driving mechanism includes a motor 19, a main gear 20 and a sub-gear 21. The motor 19 is fixedly installed on the inner wall at the bottom of the U-shaped frame 1. The main gear 20 is fixedly installed at the output shaft end of the motor 19. The sub-gear 21 is fixedly sleeved on the column 3. The main gear 20 meshes with the sub-gear 21. The motor 19 is used to control the rotation of the main gear 20. By using the meshing and transmission effect of the main gear 20 and the sub-gear 21, the rotation of the column 3 can be controlled, and thus the synchronous rotation of the lower chuck 4 and the upper chuck 8 can be realized.

[0031] In this embodiment, it should be noted that the electric hydraulic cylinder 6 and the motor 19 can be purchased in the market. The motor 19 is a low-speed motor. The electric hydraulic cylinder 6 and the motor 19 are configured with a power supply. Their circuit connection methods and control methods belong to the mature technologies in the field and are fully disclosed, so no further description will be given herein.

[0032] With the above structure, when the fixture tooling for producing the chip-breaking alloy straight flute drill provided by the present application is in use, it is convenient to clamp and fix multiple chip-breaking alloy straight flute drills simultaneously, and can horizontally rotate and adjust the multiple clamped and fixed chip-breaking alloy straight flute drills, so as to facilitate the processing of the chip-breaking alloy straight flute drills one by one. Moreover, it is convenient to simultaneously release the clamping and fixing of the multiple chip-breaking alloy straight flute drills, with simple and convenient operation, saving working time and improving work efficiency. During specific operation, one end of multiple chip-breaking alloy straight flute drills is sequentially placed on the lower protective pads 10 in the corresponding lower arc-shaped clamping grooves 5. At this time, a part of the multiple chip-breaking alloy straight flute drills located outside the corresponding lower arc-shaped clamping grooves 5 are all placed on the support ring 15. Then, control the electric hydraulic cylinder 6 to extend and operate. The output shaft end of the electric hydraulic cylinder 6 will quickly push the second shaft seat 7 and the upper chuck 8 to move vertically downward until the multiple upper protective pads 11 respectively press tightly on the chip-breaking alloy straight flute drills, and then stop the operation of the electric hydraulic cylinder 6. During the process of pressing tightly on the chip-breaking alloy straight flute drills, the upper chuck 8 will drive the connecting column 12, two cross beams 16, two vertical beams 18 and the support ring 15 to move downward. There is a certain distance between the support ring 15 and the chip-breaking alloy straight flute drills (since the time required for the upper chuck 8 to quickly move down to the position is relatively short, and the distance between the upper chuck 8 and the lower chuck 4 is also relatively small, so the multiple chip-breaking alloy straight flute drills will not fall out of the corresponding lower arc-shaped clamping grooves 5), that is, the operation of simultaneously clamping and fixing the multiple chip-breaking alloy straight flute drills is completed.

[0033] After simultaneously clamping and fixing the chip-breaking alloy straight flute drills, one of the chip-breaking alloy straight flute drills can be processed. After processing this chip-breaking alloy straight flute drill, by controlling the motor 19 to operate, the motor 19 drives the main gear 20 to rotate. The main gear 20 drives the driven gear 21, the column 3, the lower chuck 4, the connecting column 12, the upper chuck 8 and the multiple clamped and fixed chip-breaking alloy straight flute drills to rotate horizontally. When rotating another chip-breaking alloy straight flute drill to a suitable position, this chip-breaking alloy straight flute drill can be continued to be processed. According to the above operation steps, by controlling the motor 19 to operate multiple times, the multiple chip-breaking alloy straight flute drills can be horizontally rotated and adjusted to suitable positions in sequence, and the chip-breaking alloy straight flute drills can be processed one by one.

[0034] When all the multiple chip-breaking alloy straight flute drills are processed, by controlling the electric hydraulic cylinder 6 to contract and reset, the output shaft end of the electric hydraulic cylinder 6 will quickly drive the second shaft seat 7 and the upper chuck 8 to move vertically upward to return to the original position. The upper chuck 8 will drive the connecting column 12, two cross beams 16, two vertical beams 18 and the support ring 15 to move upward to return to the original position. At this time, the multiple support rings 15 will support the multiple chip-breaking alloy straight flute drills again, and the multiple processed chip-breaking alloy straight flute drills can be taken off in sequence.
