[0002] A boring machine is a machine tool mainly used for processing high-precision holes. It bores the workpiece by rotating and moving the boring cutter. There are various types of boring machines, including horizontal boring machines, floor-standing boring machines, diamond boring machines and jig boring machines, which are suitable for processing needs of different scales and precisions. Among them, the jig boring machine is equipped with a precise coordinate positioning device and can process holes with high requirements on shape, size and hole spacing. Boring machines occupy an important position in metal cutting processing and are widely used in machinery manufacturing, automobile manufacturing and other fields.

[0003] Some plate parts are thick and require deep holes. Traditional boring machines bore from one end of the hole, which is slow and makes the entire boring process inefficient. Therefore, we propose a CNC deep hole boring machine. Utility Model Content

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a CNC deep hole boring machine, comprising a base and a horizontal plate, first electric push rods are vertically installed on both sides of the surface of the base, a lower plate is transversely fixed to the end of the first electric push rod, a lower drill is installed on the surface of the lower plate, and the drill bit of the lower drill passes through the top of the lower plate, second electric push rods are vertically installed on both sides of the surface of the horizontal plate, an upper plate is transversely fixed to the end of the second electric push rod, an upper drill is installed on the surface of the upper plate, and the drill bit of the upper drill passes through the bottom of the upper plate, a support groove is opened in the middle position of the surface of the base, and the base surfaces on both sides of the support groove are locked with rotatable pressure plates by bolt connection, and the bolts pass through the pressure plates and are screwed into the screw holes on the base surface.

[0006] By adopting the above technical solution, after the plate is pressed and locked, the upper drill is driven to lower its height, while the lower drill is driven to raise its height, and the plate is bored synchronously from the top and bottom respectively, which can improve the efficiency of the boring process.

[0008] By adopting the above technical solution, when the upper drill bit and the lower drill bit are working towards each other, the trigger switch will be contacted by the resistance rod first to limit the further approach between the two, thereby protecting the drill bits.

[0009] Optionally, a rod opening is provided at a position where the base is aligned with the stop rod and the trigger switch, and the rod opening passes through the top and bottom of the base.

[0010] By adopting the above technical solution, the trigger switch or the resisting rod can pass through the base through the rod opening.

DETAILED DESCRIPTION

[0024] See also Figure 1-2 The utility model provides a technical solution: a CNC deep hole boring machine, comprising a base 1 and a cross plate 2, a support groove 11 is opened in the middle position of the surface of the base 1, and the plate to be bored can be placed in the support groove 11, and a rotatable pressing plate 5 is connected and locked by bolts 51 on the surface of the base 1 on both sides of the support groove 11. The bolts 51 pass through the pressing plate 5 and are screwed into the screw holes on the surface of the base 1. A convex portion is provided at the bottom of the pressing plate 5, and the convex portion is located below the side of the pressing plate 5 away from the bolt 51. When the bolt 51 is loosened, the pressing plate 5 can be rotated so that its convex portion is pressed on the top of the plate, and then the bolt 51 is tightened to press the locking pressing plate 5 downward, so that the pressing plate 5 presses the plate down and locks it.

[0025] Second electric push rods 21 are vertically installed on both sides of the surface of the horizontal plate 2. The protruding end of the second electric push rod 21 passes through the bottom of the horizontal plate 2. An upper plate 3 is horizontally fixed to the end of the protruding end of the second electric push rod 21. An upper drilling rig 31 is installed on the surface of the upper plate 3. The drill bit of the upper drilling rig 31 passes through the bottom of the upper plate 3. When the upper drilling rig 31 is started, it will drive the upper drill bit to rotate, and can be driven by the second electric push rod 21 to lower the height, so as to perform boring processing on the surface of the plate. A through-hole 111 is opened in the middle position of the surface of the branch groove 11, and the through-hole 111 is aligned with the drill bit of the upper drilling rig 31. The upper drill bit can pass through the through-hole 111 to the bottom of the base 1.

[0026] In order to improve the efficiency of boring deep holes, the present application adopts a method of synchronous boring at both ends. A first electric push rod 12 is vertically installed on both sides of the surface of the base 1. The protruding end of the first electric push rod 12 passes through the bottom of the base 1, and the end of the first electric push rod 12 is horizontally fixed with a lower plate 4. A lower drill rig 41 is installed on the surface of the lower plate 4, and the drill bit of the lower drill rig 41 passes through the top of the lower plate 4. When the upper drill rig 31 is lowered to drill, the lower drill rig 41 can be synchronously driven to move upward through the through-opening 111, and the plate is synchronously bored from the bottom.

[0027] When the above method is used for bidirectional boring processing, the drill bit may be damaged by contact. In order to solve this problem, the present application connects a support rod 421 to the upper side of the lower plate 4 through a lower screw barrel 42, and the lower side of the support rod 421 is connected to the lower screw barrel 42 by a threaded connection. A trigger switch 422 is installed on the top of the support rod 421. At the same time, a push rod 321 is connected to the lower side of the upper plate 3 aligned with the trigger switch 422 through an upper screw barrel 32, and the upper side of the push rod 321 is connected to the upper screw barrel 32 by a threaded connection, and a rod opening 13 is opened at the position where the base 1 is aligned with the push rod 321 and the trigger switch 422. The rod opening 13 runs through the upper and lower sides of the base 1, so that no matter what length of drill bit is used, it can be turned before work by rotating the push rod 321. The height of the support rod 321 or the trigger switch 422 is adjusted by means of the rod 321 or the support rod 421. The support rod 321 will be lowered together with the upper drill bit, and the trigger switch 422 will be raised together with the lower drill bit. It is necessary to adjust the support rod 321 to contact the trigger switch 422 before the upper and lower drill bits contact, to ensure that the upper drill bit and the lower drill bit are as close as possible to avoid contact when contacting, and at the same time, the close position is made as close as possible to the middle position of the plate to be bored, thereby limiting the first electric push rod 12 from continuing to drive the lower drill rig 41 to rise, or limiting the second electric push rod 21 from continuing to drive the upper drill rig 31 to descend, to avoid damage to the drill bit, and then the upper drill rig 31 or the lower drill rig 41 whose movement is not restricted continues to drill the hole completely.

[0028] When in use, the upper drill rig, the first drill rig, the first electric push rod, the second electric push rod and the trigger switch are all connected to the industrial control computer. First, the upper drill rig 31 and the lower drill rig 41 are replaced with the drill bits of the required size, and then the support rod 321 is rotated to make it twisted upward or downward, and the height of the support rod 421 is adjusted in the same way to change the height of the trigger switch 422, ensuring that the upper drill rig 31 is lowered and the lower drill rig 41 is raised, so that the upper and lower drill bits are close to each other, and before the two contact, ensure that the support rod 321 can contact the trigger switch 422 at the top of the support rod 421, and then control the first electric push rod 12 and the second electric push rod 21 to reset the upper drill rig 31 and the lower drill rig 41, and place the plate to be bored in the support groove 11 for support, and align the hole to be bored with the drill bits of the upper drill rig 31 and the lower drill rig 41, and at the same time align it with the through-opening 111, and then rotate the pressure plates 5 on both sides so that the downward protruding part of the bottom moves and presses above the plate. , then tighten the bolt 51 to press the plate down and lock it, then start the upper drill rig 31 and the lower drill rig 41 to drive the upper and lower drill bits to rotate, and at the same time control the second electric push rod 21 and the first electric push rod 12 to synchronously drive the upper drill rig 31 to lower the height and the lower drill rig 41 to raise the height, and then use the upper and lower drill bits to synchronously bore the holes to be bored from the top and bottom, until the upper drill bit and the lower drill bit are about to touch, the push rod 321 will first resist and press the trigger Switch 422 is used to limit the position. At this time, the first electric push rod 12 drives the lower plate 4 and the lower drill rig 41 to move downward and reset, while the second electric push rod 21 continues to drive the upper plate 3 and the upper drill rig 31 to lower the height, ensuring that the upper drill bit continues to bore the hole downward and penetrates the hole processed by the lower drill bit. Then, the second electric push rod 21 drives the upper plate 3 and the upper drill rig 31 to reset, stops the work of the upper drill rig 31 and the lower drill rig 41, loosens the bolt 51 and removes the pressure plate 5, and the plate can be removed.
