Description

Technical Field

[0001] The utility model relates to a relatively large range, specifically a multi-type drill bit placement rack for cutting tool processing. Background Technique

[0002] A drill bit is a metal cutting tool, mainly including three parts: a cutting edge part, a core part, and a shank part. The cutting edge part is the main part of the drill bit for cutting the workpiece. It is usually a three-dimensional triangular pyramid structure, with cracks and cutting grooves on its face, and cuts the workpiece by rotating and advancing; the core part is usually cylindrical, and its function is to guide the chip discharge and strengthen the rigidity of the cutting edge part to avoid the cutting edge part from breaking; the shank part is used to fix on machine tools such as drill presses and lathes to enable it to rotate and advance.

[0003] During the production process of drill bits, it is usually necessary to fix the drill bits on a rotatable fixture to perform rough machining and finish machining on the cutting edge part and the core part of the drill bit during the rotation of the drill bit. At present, this step is mostly completed on a lathe, but the lathe can only clamp one drill bit at a time. After completing the processing of one drill bit, it takes a certain amount of time to load and unload on the fixture of the lathe before starting to process the next drill bit, which is not conducive to improving the production efficiency of drill bits and needs to be improved.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features.

[0021] Please refer to Figures 1 to 3 , in the embodiment of the present invention, a multi-type drill bit placement rack for cutting tool machining includes a base 1. A plurality of fixed ears 2 are fixedly installed on the outer wall of the base 1. The top of the base 1 is rotatably connected to a housing 4 through a rotary table bearing 3. A plurality of turntables 9 are rotatably installed on the top of the housing 4. Clamps 10 for clamping drill bits are fixedly installed on the top surfaces of the turntables 9. The clamps 10 can adopt clamping devices such as three-jaw chucks and drill chucks suitable for drill bits of different diameters, or can also be customized special tooling suitable for special drill bits. Motors 5 are fixedly installed at the corresponding positions of the outer wall of the housing 4 and each turntable 9. The motors 5 are used to drive the corresponding turntables 9 to rotate on the housing 4. A clamping mechanism is installed on the base 1.

[0022] By adopting the above solution, when in use, after fixedly installing the base 1 on the processing platform of the processing equipment, the housing 4 can be rotated on the base 1 to move the fixture 10 clamping the drill bit to the processing station. Then, use the clamping mechanism to fix the housing 4 on the base 1, and start the motor 5 to drive the fixture 10 to drive the drill bit to rotate. After that, the processing equipment can be started to process the drill bit. During this process, the staff can clamp the drill bit on other fixtures 10 that are not participating in the processing. After the processing equipment finishes processing the previous drill bit, only need to rotate the housing 4 on the base 1 to move the fixture 10 clamping the unprocessed drill bit to the processing station, and then the next processing can be started, thus effectively avoiding the occupation of processing time by the loading and unloading of the drill bit, improving the production efficiency of the drill bit, and having a good use effect.

[0023] Specifically combined with Figure 1 , in an embodiment of the present utility model, several of the turntables 9 are evenly distributed in a circumferential manner on the top of the housing 4. A partition 11 for separating each turntable 9 from each other is fixedly installed on the top of the housing 4. The number of turntables 9 can be 2 or 3. When 3 turntables 9 are adopted, this device can be used on a processing equipment with double processing heads. One processing head performs rough machining on the drill bit, and the other processing head performs finish machining on the drill bit, thereby further improving the processing efficiency of the drill bit. The setting of the partition 11 can block the iron filings generated during the processing and prevent the flying iron filings from causing harm to the operator.

[0024] Specifically combined with Figure 2 , in an embodiment of the present utility model, a rotating shaft 7 is rotatably installed at the corresponding position of each turntable 9 inside the housing 4. A second bevel gear 8 is fixedly sleeved on the outer wall of the rotating shaft 7. The top end of the rotating shaft 7 passes through the housing 4 and is fixedly connected to the bottom of the turntable 9. The output shaft of the motor 5 penetrates into the housing 4 and is fixedly connected to a first bevel gear 6. The first bevel gear 6 meshes with the corresponding second bevel gear 8.

[0025] Through the cooperation of the first bevel gear 6 and the second bevel gear 8, only by starting the motor 5, the rotating shaft 7 can be driven to drive the turntable 9 to rotate, thereby driving the drill bit to be processed to rotate by using the fixture 10.

[0026] Specifically combined with Figure 2 and Figure 3 , in an embodiment of the present utility model, a connecting shaft 16 is fixedly connected to the center of the bottom of the housing 4. A slip ring 17 is installed through the top of the base 1. The inner ring of the slip ring 17 is sleeved on the connecting shaft 16. A second wire groove 19 is opened at the bottom of the base 1. A first wire groove 18 is opened at the corresponding position of the bottom of the housing 4 and each motor 5.

[0027] Through the arrangement of the first wire groove 18, the slip ring 17 and the second wire groove 19, it is convenient to lay the power supply lines of the respective motors 5 and avoid interference of the power supply lines of the motors 5 with the rotation of the housing 4.

[0028] Specifically, in combination Figure 1 , in an embodiment of the present invention, the clamping mechanism includes two vertical plates 12 symmetrically and fixedly installed on the top of the base 1. The outer walls of the vertical plates 12 are fixedly installed with hydraulic cylinders 13. The push rod ends of the hydraulic cylinders 13 are fixedly installed with clamping plates 14. The two clamping plates 14 are symmetrically distributed on both sides of the housing 4. A plurality of guide rods 15 are slidably penetrated through the vertical plates 12. One end of the guide rod 15 is fixedly connected to the corresponding clamping plate 14.

[0029] Before processing the drill bit, start the two hydraulic cylinders 13 to push the clamping plates 14 to move towards the housing 4, so as to clamp the housing 4 on the base 1 by using the two clamping plates 14, which can ensure the stability of the housing 4 during the processing and avoid displacement of the housing 4 on the base 1.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
