The machine head is arranged above the workbench through a lifting rod, the drill bit and the lifting motor are respectively arranged at the bottom of both sides of the machine head, the drill bit is arranged vertically to the workbench, and the punching tool includes a positioning slider and a slide rail, the positioning slider is slidably arranged on the slide rail, and the slide rail is movably arranged on the workbench. The multi-point punching machine for pipe fittings of the present invention can realize continuous multi-point punching of the same copper pipe by means of a punching tool arranged on a workbench, and the position and angle of the copper pipe can be adjusted during the punching process, without stopping the machine to replace the tool or adjusting the position and angle of the copper pipe, thereby ensuring the continuity of the punching and greatly improving the work efficiency; and the punching tool ensures the accuracy of each punching and improves the product quality, but when the pipe fitting punching machine is in use, the feeding mechanism of the pipe fitting punching machine can be accurately positioned, and the pipe fitting can be accurately fed into the punching position of the punching machine, and then the feeding mechanism can feed according to the setting, but in order to facilitate the feeding mechanism to feed, generally a pulling hole is opened at the pipe mouth of the pipe fitting, and then the feeding mechanism is buckled on the pulling hole, which can drive the pipe to move, but this will cause the pipe to need to be intercepted for a section during use, which will cause waste. Utility Model Content

[0003] The purpose of the utility model is to provide a pipe punching machine with a precise positioning mechanism. In order to facilitate the feeding of the feeding mechanism, a pulling hole is generally opened at the pipe mouth of the pipe fitting, and then the feeding mechanism is buckled on the pulling hole to drive the pipe to move. However, this will cause the pipe to be intercepted for a section during use, which will cause waste.

[0004] The above technical objectives of the utility model are achieved through the following technical solutions:

[0005] A pipe punching machine with a precise positioning mechanism comprises a feeding mechanism, one side of the feeding mechanism is fixedly connected to a fixing frame, one side of the fixing frame is fixedly connected to a U-shaped frame, a rotating hole is opened at the bottom of the U-shaped frame, and a bidirectional screw is rotatably connected between the inner walls of the rotating hole, both ends of the bidirectional screw are rotatably connected to the inner wall of the U-shaped frame, a bracket is provided with a threaded sleeve on the outer surface of the bidirectional screw, two sliding holes are opened on one side of the bracket, and a support rod is slidably connected to the inner wall of the sliding hole, a pressure plate is fixedly connected between one end of each of the support rods, a protective pad is fixedly connected to one side of the pressure plate, a limiting hole is opened on one side of the bracket, the inner wall of the limiting hole is slidably connected to the limiting rod, and both ends of the limiting rod are fixedly connected to the outer surface of the U-shaped frame.

[0006] By adopting the above technical scheme, the protective pad can provide a certain protection effect, which can effectively prevent the high pressure of the two pressure plates from causing extrusion, deformation and damage to the pipe fittings. At the same time, the bidirectional screw is used as an adjustment. The rotation of the bidirectional screw will drive the bracket mounted on the bidirectional screw to move up and down, and the action of the bidirectional screw will cause the two brackets to move in opposite directions, so that the pressure plate can be clamped to the wall of the pipe fitting, thereby fixing the pipe fitting and allowing the feeding mechanism to move with the pipe fitting. The limit rod can prevent the bracket from rotating under the action of the rotation of the bidirectional screw.

[0007] The utility model is further configured as follows: the other end of the support rod is fixedly connected with a fixing block, and the outer surface of the support rod is provided with a spring.

[0008] By adopting the above technical solution, the moving trajectory of the support rod can be limited to a certain extent by the fixing block.

[0009] The utility model is further configured as follows: one end of the spring is fixedly connected to one side of the bracket, and the other end of the spring is fixedly connected to one side of the fixing block.

[0010] By adopting the above technical solution, a force can be applied to the fixing block through the spring, so that the pressure plate can be kept at a certain distance from the bracket, and the pressure plate has a certain buffering effect when performing the clamping work.

[0011] The utility model is further configured as follows: a protective shell is fixedly connected to the top of one of the fixing frames, and a motor is installed inside the protective shell.

[0012] By adopting the above technical solution, the protective shell can protect the motor to a certain extent to prevent the motor from being damaged.

[0013] The utility model is further configured as follows: a first gear is fixedly sleeved on the outer surface of the bidirectional screw, and a chain is arranged on the outer surface of the first gear.

[0014] By adopting the above technical solution, the bidirectional screw can be driven to rotate by the first gear.

[0015] The utility model is further configured as follows: a second gear is fixedly sleeved on the output end of the motor, and the second gear is transmission-connected to the first gear through a chain.

[0016] By adopting the above technical solution, the second gear and the first gear are matched with each other through the chain, so that the motor can easily control the rotation of the bidirectional screw.

[0017] In summary, the beneficial technical effects of the utility model are:

[0018] (1) The protective pad can provide a certain degree of protection, which can effectively prevent the pressure of the two pressure plates from being too large, causing extrusion, deformation and damage to the pipe fittings. At the same time, the bidirectional screw acts as an adjustment. The rotation of the bidirectional screw will drive the bracket mounted on the bidirectional screw to move up and down, and the action of the bidirectional screw will cause the two brackets to move in opposite directions, so that the pressure plate can be clamped to the wall of the pipe fitting, thereby fixing the pipe fitting and allowing the feeding mechanism to move with the pipe fitting. The limit rod can prevent the bracket from rotating under the action of the rotation of the bidirectional screw. The fixed block can limit the moving trajectory of the support rod to a certain extent. The spring can give the fixed block a force, so that the pressure plate can be kept at a certain distance from the bracket. The pressure plate has a certain buffering effect when clamping.

[0019] (2) The protective shell can protect the motor to a certain extent to prevent damage to the motor. The first gear can easily drive the bidirectional screw to rotate. The chain makes the second gear and the first gear cooperate with each other, so that the motor can easily control the rotation of the bidirectional screw. BRIEF DESCRIPTION OF THE DRAWINGS
