DETAILED DESCRIPTION

[0023] The utility model is further described below in conjunction with the accompanying drawings.

[0024] The orientations mentioned in this specification are based on the orientations of the valve cover drilling and tapping machine of the utility model during normal operation, and do not limit the orientations during storage and transportation. They only represent relative position relationships, not absolute position relationships.

[0025] like Figure 1 As shown, a valve cover drilling and tapping machine includes a turntable 1 and a turntable driving device. The turntable 1 is a disc structure with a rotating shaft fixed to the middle bottom. The rotating shaft is connected to the turntable driving device through the turntable driving device to drive the turntable 1 to rotate.

[0026] A fixture 2 is installed on the turntable 1 in an adjustable position, and the valve cover 3 is clamped on the fixture 2. A waist-shaped hole 11 is provided on the turntable 1, and the fixture 2 is slidably installed in the waist-shaped hole 11. Because of the clamping method of the valve cover 3, the waist-shaped hole 11 is arranged along the radial direction of the turntable 1 in this embodiment, so that when adjusting the position, the fixture 2 can be pushed in the waist-shaped hole 11. A drilling machine 41 and a tapping machine 42 are provided on the side of the turntable 1, and the turntable driving device drives the fixture 2 to switch between the drilling machine 41 and the tapping machine 42. The drilling machine 41 and the tapping machine 42 can be manual or automatic.

[0027] By clamping the valve cover 3 on the fixture 2, the turntable 1 is driven by the turntable driving device to first enter the drilling machine 41 for drilling, and then enter the tapping machine 42 for tapping, so that drilling and tapping can be completed in one clamping, thereby greatly improving work efficiency.

[0028] In order to achieve simultaneous drilling and tapping and improve work efficiency, at least two clamps 2 are provided. In this embodiment, five clamps 2 are provided, and the five clamps 2 are evenly arranged around the periphery of the turntable 1. The turntable 1 is provided with five working positions, and each working position corresponds to a clamp 2. Two drilling machines 41 and tapping machines 42 are provided respectively, and the five working positions are: disassembly position, first drilling position, first tapping position, second drilling position, and second tapping position. The two drilling machines 41 and tapping machines 42 are respectively located at different working positions. The drill bit of the drilling machine 41 at the first drilling position and the drill bit of the drilling machine 41 at the second drilling position correspond to different mounting holes 31 on the valve cover 3, but the drill bit of the drilling machine 41 at the first drilling position and the tapping machine 42 at the first tapping position correspond to the same mounting hole 31 on the valve cover 3; the tapping machine 42 at the first tapping position and the tapping machine 42 at the second tapping position correspond to different mounting holes 31 on the valve cover 3 respectively, but the drill bit of the drilling machine 41 at the second drilling position and the tapping machine 42 at the second tapping position correspond to the same mounting hole 31 on the valve cover 3.

[0029] The turntable driving device drives the turntable 1 to rotate at the same angle of 72°, thereby controlling the fixture 2 to switch between the five working positions and finally return to the disassembly position, so that the drilling and tapping of all the mounting holes 31 can be completed in one clamping, thereby greatly improving the work efficiency. The turntable driving device can use a stepping motor, and can be automatic, manual, or mixed.

[0030] like Figure 2 and Figure 3 As shown together, the clamp 2 includes a slide plate 21 slidably mounted on the turntable 1, and a fixing bolt 211 is provided between the slide plate 21 and the turntable 1, and the slide plate 21 is fixed to the turntable 1 by the fixing bolt 211. A positioning column 212 is fixedly mounted on the slide plate 21, and the positioning column 212 is inserted into the positioning hole 32 of the valve cover 3. In this embodiment, four positioning holes 32 are provided on the valve cover 3, so four corresponding positioning columns 212 are also provided. During installation, the valve cover 3 is inserted into the positioning column 212, thereby realizing the rapid positioning of the valve cover 3. A pressing plate 22 is also provided on the slide plate 21, and the pressing plate 22 is pressed on the top of the valve cover 3. A locking column 23 is provided between the pressing plate 22 and the slide plate 21, and the locking column 23 presses the valve cover 3 on the slide plate 21.

[0031] like Figure 3 and Figure 4 As shown together, a fixing seat 24 is provided on the side of the valve cover 3 on the slide plate 21, and one end of the slide plate 21 is hinged on the fixing seat 24. The bottom of the locking column 23 is rotatably mounted on the fixing seat 24, and a cam block 231 is fixed on the top of the locking column 23. A long hole 221 is provided on the pressure plate 22, and the locking column 23 passes through the long hole 221. The narrow side length of the cam block 231 is less than the width of the long hole 221, and the long side length of the cam block 231 is greater than the width of the long hole 221.

[0032] The slide plate 21 is flipped around the hinge point, the locking column 23 passes through the long hole 221, and then the locking column 23 is rotated, and the cam block 231 is clamped on the upper end of the long hole 221, so that the pressure plate 22 is pressed on the valve cover 3, and the valve cover 3 is quickly locked. When the pressure plate 22 needs to be loosened, the locking column 23 is rotated, and the cam block 231 passes through the long hole 221, so that the pressure plate 22 is flipped outward, and the valve cover 3 is loosened. In order to ensure stable locking, four pressure plates 22 are arranged around the valve cover 3.

[0033] In this embodiment, the cam block 231 is a diamond-shaped block, thereby reducing the difficulty of processing the cam block 231 .

[0034] like Figure 3 and Figure 5As shown together, in order to facilitate the discharge of iron chips after drilling and tapping, a leakage hole 25 is provided on the fixture 2 corresponding to the drilling position, and a discharge port 12 is provided on the turntable 1 corresponding to the leakage hole 25.

[0036] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown together, the working process of a valve cover drilling and tapping machine is as follows:

[0037] Adjust the relative positions of the two drilling machines 41 and the two tapping machines 42 and the fixture 2, and make the five fixtures 2 have the same distance from the center of the turntable 1, to ensure that the drill bit of the drilling machine 41 at the first drilling position and the tap of the tapping machine 42 at the first tapping position correspond to the same mounting hole 31 on the valve cover 3; the tap of the tapping machine 42 at the first tapping position and the tap of the tapping machine 42 at the second tapping position correspond to different mounting holes 31 on the valve cover 3, but the drill bit of the drilling machine 41 at the second drilling position and the tap of the tapping machine 42 at the second tapping position correspond to the same mounting hole 31 on the valve cover 3; clamp the valve cover 3 to the fixture 2, and perform processing in sequence according to the process flow.
