The utility model provides a kind of processing frock of marine high-power diesel engine cylinder cover inclined hole, it is related to marine diesel engine parts processing technical field, including base, backplate, positioning plate, cushion block, drill jig plate body, pin shaft and drill jig cover;The backplate and the cushion block are installed on the base top, the positioning plate is fixed on the backplate, the drill jig plate body is positioned fastening by the pin shaft, the drill jig cover is set on the drill jig plate body.The utility model solves the problem that different frock needs to be called when processing center processes cylinder cover inclined hole, there is the problem of repeated up and down activity, not only increase production cost, also reduce production efficiency, also difficult to guarantee the processing accuracy of inclined hole, it can lead to inclined hole drilling deviation due to angle problem, affect the cooling effect of cylinder cover.

The invention relates to the technical field of deep hole drilling machines, in particular to an ultrasonic numerical control deep hole drilling machine. The technical scheme comprises a machine body; the guide rail is mounted on the machine body; the workpiece fixing module and the drilling module are slidably mounted at two ends of the machine body through guide rails; the first limiting module is installed on the machine body and located between the machine body and a first limiting sleeve is embedded in the first limiting module. The vertical plate is installed at the end, close to the drilling module, of the machine body. The guide rod is mounted on the machine body through the first limiting module and the vertical plate; the second limiting module is slidably installed on the guide rod and locked and fixed through a bolt, and a second limiting sleeve is embedded in the second limiting module. The hydrodynamic force and cooling system is connected between the drilling module and the workpiece fixing module, and when the drilling module conducts feeding motion, the system drives the workpiece fixing module to move oppositely and conveys cooling liquid to a machining part. Accurate limiting is achieved through the double limiting modules, the fluid system synchronously drives workpieces to feed oppositely and convey cooling liquid, and the drilling precision and efficiency are effectively improved.

The utility model discloses a PVC tubular product outer wall drilling device, including an operation platform, be provided with the fixture mechanism for placing PVC tubular product and can be to PVC tubular product drilling place clamping fixed on the operation platform, can be to PVC pipe and carry out the trepanning of opening operation trepanning mechanism and can pull the traction mechanism of PVC pipe movement, the trepanning mechanism is across the top of fixture mechanism, and the traction mechanism is located downstream of fixture mechanism, the utility model has realized the alignment of fixing when the drilling of PVC tubular product, has effectively prevented the drilling deviation problem caused by the shaking of tubular product in the drilling process, has improved the precision and quality of drilling, has realized the automatic movement and rotation of PVC tubular product to the accuracy of drilling is ensured, and the labor intensity is reduced, and the processing efficiency is improved.

The invention discloses a drilling machine drilling deviation prevention device with a built-in steel bar detection function, and belongs to the technical field of drilling machines. The drilling mechanism is arranged at the bottom of the drill rod; and the drilling deviation prevention mechanism is arranged between the drilling rod and the drilling mechanism, and the drilling deviation prevention mechanism comprises a drilling deviation prevention module, a steel bar detection sensor, a signal processing module, a battery module and a wireless transmitting module. According to the drilling machine drilling deviation prevention device with the built-in steel bar detection function, the steel bar detection sensor, the signal processing module and the wireless transmitting module are highly integrated in the drilling deviation prevention module, the magnetic field change in the direction right opposite to a probe can be scanned in real time in the drilling process, the steel bar distance can be estimated, and once a steel bar cage is detected, an alarm is given out immediately; a drilling machine operator is guided to adjust the position of a drill bit, the situation that finding is carried out afterwards is changed into process avoiding, meanwhile, the steel bar detection sensor can judge the direction and distance of a steel bar cage relative to the drill bit, and the operator can carry out reverse adjustment according to alarm information.
