For example, Figure 1 shows the structure of a cutter head 1 of a drilling and tapping machine Drilling&Tapping Machine. The periphery of the cutter head 1 is sandwiched with multiple knives that are connected to each other. The handle 11 uses the motor as the power source 12 to output power, which is transmitted from the indexer 13 to the gear set 14, and is converted into the rotation angle of the rotating shaft 15 through the gear ratio, so that one of the plurality of handles 11 on the periphery of the cutter head 1 is rotated to a fixed point for attacking. teeth, grooving and other processing steps.

The gear set 14 on the back of the cutter head 1 is exposed in the working range of cutting. Metal chips are generated during the drilling, milling or grooving process of the workpiece, and the gear set 14 is easily splashed and interferes with the smoothness of the meshing transmission, and even affects the Whether the main shaft head socket handle 11 is firm or not.

In view of this, in order to solve the aforementioned problems, the applicant of the utility model hereby researches and creates a cutter head power source positioning structure suitable for drilling and tapping machines.

Contents of the invention

One of the purposes of the utility model is to provide a drilling and tapping machine that protects the transmission power components in the box, so that metal shavings are no longer splashed and mixed between the engaging components, and the processing accuracy is reduced to the minimum. Influence degree of cutter head power source positioning structure.

In order to achieve the aforementioned purpose, the utility model provides a positioning structure for the power source of the cutter head of the drilling and tapping machine, including: a cutter head arranged on the machine table, and a plurality of jacket seats are equidistantly arranged on the periphery of the cutter head, and each clamp The sleeve clamp has a handle for connecting the tool, and the center of the cutter head has a rotating shaft inserted into the indexing box. The indexing box is arranged between the cutter head and the machine table. The indexing plate in the indexing box is connected, and the side of the indexing plate different from the cutter head is equidistantly provided with multiple pulleys; two adjacent pulleys are engaged with a screw part, and the screw part is set on a driven shaft One end of the driven shaft is assembled with a roller bearing on the indexing box, and the port is sealed by a closure. The other end of the driven shaft is assembled with the roller bearing, and passes through the indexing box to connect with a gear. A driven wheel inside the box is connected, and the driven wheel is engaged with a main wheel, and the main wheel is connected to a transmission shaft of a power source, and the transmission shaft passes through a load seat for the aforementioned power source to be fixed, and the load seat is Covers the open end of the gearbox.

According to the positioning structure of the power source of the drilling and tapping machine cutter head, it has the following advantages:

a includes rotating shaft 24, pulley 33, screw part 34, driven wheel 42, main wheel 43 and transmission shaft 44, etc., which are all protected in the indexing box 3 and the gear box 41, and the metal shavings produced during the processing will not Re-splash is mixed between the elements in the meshing relationship, and the influence on the processing accuracy is minimized.

b. Under the condition of not interfering with the operation of each tool handle 23 of the cutter head 2, the distance between the transmission elements is smaller than that of the prior art. In terms of the transmission loss of mechanical energy, the utility model has a lower loss than the prior art advantage.

Detailed ways

Fig. 2 and Fig. 3 are the embodiments of the power source of the cutter head applicable to the drilling and tapping machine. The drawing shows a cutter head 2 installed on the machine table 21, and the periphery of the cutter head 2 is equidistantly provided with a plurality of jacket seats. 22. Each of the jacket seats 22 clamps a knife handle 23 that connects the cutter.

The center of the cutterhead 2 has a rotating shaft 24 inserted into the indexing box 3. The indexing box 3 is arranged between the cutterhead 2 and the machine table 21. The rotating shaft 24 passes through a case cover 31 and connects with a 3, the indexing plate 32 is connected, and the indexing plate 32 is provided with a plurality of pulleys 33 equidistantly from the side of the cutterhead 2.

Wherein, two adjacent pulleys 33 are engaged with a screw part 34, and the screw part 34 is arranged on a driven shaft 35, and one end of the driven shaft 35 is threaded with a roller bearing 36 and mounted on the indexing box 3, The port is sealed with a closure 37 . The driven shaft 35 assembles the other end of the roller bearing 36, passes through the indexing box 3 and connects with a driven wheel 42 inside a gear box 41, and the driven wheel 42 engages with a main wheel 43, and the main wheel 43 Connected to a transmission shaft 44 of a power source 4 , the transmission shaft 44 passes through a load seat 45 for fixing the power source 4 , and the load seat 45 covers the open end of the gear case 41 .

When the input information of the drilling and tapping machine is transmitted to the power source 4, the power is output from the transmission shaft 44 to rotate the main wheel 43, so that the driven wheel 42 in meshing relationship rotates according to the gear ratio, and the driven shaft 35 is synchronized. The screw part 34 is driven to rotate, and the screw part 34 makes the pulley 33 in the engaged state drive the index plate 32 to rotate by itself according to the pitch.

The rotation of the index plate 32 together with the rotating shaft 24 drives the cutter head 2 to rotate an angle, causing one of the plurality of jacket seats 22 on the periphery to be displaced to a fixed position, and the drilling and tapping machine can clamp the handle 23 of the jacket seat 22 Machining steps for a specific tool.
