Description

Technical Field

[0001] The utility model relates to an oblique hole processing device, in particular to an oblique hole processing device for a metal round tube. Background Art

[0002] At present, in order to perform inclined hole processing on metal round tubes in batches, it is inevitable to use the positioning tool for the metal round tubes. That is, during processing, the tool is first installed on the workbench of the existing punching equipment to position the metal round tube, and the punching drill is aligned with the eccentric position of the metal round tube. Therefore, when the punching drill is pressed down vertically to drill, an inclined hole can be formed. Since the punching equipment in the prior art generally presses down vertically to drill, if the inclined hole is processed for the metal round tube, the eccentric impact force is easy to cause the metal round tube to deviate to one side. Therefore, a more stable positioning support for the metal round tube is required. Utility Model Content

[0003] In order to solve the above technical problems, the purpose of the utility model is to provide a metal round tube inclined hole processing device, which can not only provide the metal round tube with stable positioning support, but also greatly shorten the loading and unloading transition time during drilling, improve production efficiency, and also ensure that the axial drilling position is always fixed, thereby improving the drilling accuracy.

After loading and before drilling, the positioning part and the pressing part can also limit the end axis of the two ends of the metal round tube. Therefore, it can be ensured that the axis position of each hole is constant. At the same time, due to the positioning of the clamping block on the pressing part for the side wall of the metal round tube, based on the clamping of the positioning part and the two ends of the pressing part, auxiliary side wall position fixing can be performed, thereby further preventing the metal round tube from shifting during drilling.

After loading, the pulling cylinder is started again to drive the positioning pressure block to be pressed onto the positioning bottom block, thereby realizing the initial positioning of the metal round tube.

[0013] The beneficial effect of the utility model is that when one group of positioning parts holds the metal round tube tightly and moves with the linear slide to the bottom of the drill bit, the other positioning parts can perform the loading and unloading operations of the metal round tube, thereby greatly saving the transition time required for loading and unloading, thereby improving production efficiency, and after loading and before drilling, the positioning parts and the top pressing parts can also limit the end axis of the two ends of the metal round tube, so that it can be ensured that the axis position of each hole is constant, and at the same time, due to the positioning of the clamping block on the top pressing part for the side wall of the metal round tube, based on the clamping of the two ends of the positioning part and the top pressing part, auxiliary side wall position fixing can be performed, thereby further preventing the metal round tube from deviating during drilling.

[0021] Example 1

[0022] like Figure 1-4As shown, a device for processing oblique holes in a metal round tube comprises, in this embodiment, a positioning base plate 1, a linear slide plate 2, a reciprocating drive member 3, a positioning portion 4, a pressing portion 5 and a clamping block 6. The positioning base plate 1 is installed on a workbench of a punching device, and a group of linear slide plates 2 are connected to the top of the positioning base plate 1 along a straight line for sliding movement. The linear slide plates 2 are driven by the reciprocating drive member 3 to perform a straight line reciprocating motion, and at least two groups of positioning portions 4 are sequentially arranged side by side along the sliding direction. The positioning portion 4 is used to embrace one end of the metal round tube, and has an abutment plate for abutting and limiting the end of the metal round tube. The pressing portion 5 is connected to one side of the positioning base plate 1, and a clamping block 6 is installed thereon. The clamping block 6 is used to hold the side wall of the metal round tube tightly when the pressing portion 5 presses the other end of the metal round tube to the positioning portion 4.

[0023] At this point, when one group of positioning parts 4 holds the metal round tube tightly and moves to the bottom of the drill bit with the linear slide 2, the other positioning parts 4 can perform loading and unloading operations on the metal round tube, thereby greatly saving the transition time required for loading and unloading, thereby improving production efficiency. After loading and before drilling, the positioning parts 4 and the pressing parts 5 can also limit the end axis of the two ends of the metal round tube, so that the axis position of each hole can be ensured to be constant. At the same time, due to the positioning of the side wall of the metal round tube by the clamping block 6 on the pressing part 5, auxiliary side wall position fixing can be performed on the basis of clamping the two ends of the positioning parts 4 and the pressing parts 5, thereby further preventing the metal round tube from shifting during drilling.

[0024] Example 2

[0025] A device for processing inclined holes in metal round tubes. In this embodiment, it is further defined based on embodiment 1. The positioning portion 4 includes a positioning bottom block 41 and a positioning pressure block 42. The positioning bottom block 41 and the positioning pressure block 42 are provided with arc holes. The two groups of arc holes are butted together to form a cylindrical hole for enclosing and limiting the outside of the metal round tube, and abutment blocks are also provided at the ends thereof. The abutment block on one side of the positioning bottom block 41 is abutment block 1 43, and the abutment block on one side of the positioning pressure block 42 is abutment block 2 44. Abutment block 1 43 and abutment block 2 44 are butted together to form an abutment plate for limiting the end of the metal round tube. The positioning bottom block 41 and the positioning pressure block 42 are connected by bolts, and the positioning pressure block 42 is also provided with a drill hole for a drilling drill to pass through to drill holes in the internal metal round tube.

[0026] The positioning part 4 also includes a group of positioning support plates 45 for supporting the bottom of the metal tube. The positioning support plates 45 are connected to the positioning bottom block 41 through a positioning plate 46 on one side, and the positioning plate 46 is against one side of the metal tube to more accurately determine the position of the metal tube.

[0027] The bottom of the positioning support plate 45 is inserted and positioned in the slot of the linear slide 2, and one side thereof is inserted and installed with the positioning plate 46, and the end of the positioning plate 46 facing away from the positioning support plate 45 is also inserted and installed on the positioning bottom block 41. At this point, the supporting position can be quickly adjusted by adjusting the insertion position of the positioning support plate 45 and replacing the positioning plates 46 of different lengths.

[0028] The pressing part 5 includes a pressing bottom plate 51, a pressing slide plate 52, a pressing plate 53 and a pressing driving member 54. The pressing bottom plate 51 is fixed to one side of the positioning part 4, and a group of pressing slide plates 52 are slidably mounted on the pressing bottom plate 51. The pressing slide plates 52 are driven by the pressing driving member 54 to perform linear reciprocating motion, and a pressing plate 53 is fixed on the pressing bottom plate 51. The clamping block 6 is provided with two groups located on the pressing plate 53. Each group of clamping blocks 6 includes two groups of claw body units 61 driven by a screw rod 62 to move in opposite directions. The screw rod 62 is driven by a screw rod 62 to move in opposite directions. Motor 1 drives the rotation, and two sets of clamping blocks 6 are clamped on the top and bottom ends of the metal round tube accordingly. Therefore, when drilling, the two sets of clamping blocks 6 clamp and fix the side walls of the metal round tube, which can better buffer the eccentric rotation pressure of the drill bit on the metal round tube. At this point, the positioning part 4 and the pressing part 5 can assist in pressing the two ends of the metal round tube for positioning, and the reciprocating drive part 3 and the pressing drive part 54 both use the corresponding screw rod 2 and the motor 2 for driving the screw rod 2 to drive the rotation to realize reciprocation.

[0029] A group of waste chip grooves 47 are also provided in the positioning bottom block 41, and a chip removal hole 48 is opened on the abutment block. The bottom end of the waste chip groove 47 is connected to the waste chip hole and tilted downward to one side of the chip removal hole 48. The outlet end of the chip removal hole 48 is connected to the exhaust fan through a hose. At this point, when drilling, the exhaust fan can also be started at the same time to discharge the waste chips.

[0030] Example 3

[0031] A device for processing inclined holes in metal round tubes. In this embodiment, relative to Embodiment 2, the positioning bottom block 41 and the positioning pressure block 42 are replaced by being locked and connected via a pulling cylinder. Therefore, there is no need to manually install the metal round tube in the hole. The positioning pressure block 42 can be lifted by starting the pulling cylinder to leave enough space for loading the metal round tube. After loading, the pulling cylinder can be started again to drive the positioning pressure block 42 to be pressed onto the positioning bottom block 41, thereby realizing the initial positioning of the metal round tube.

[0032] The working principle of the utility model is:

[0033] The positioning part 4 is used to hold the metal round tube tightly and move with the linear slide plate 2 to the bottom of the drill bit. At this time, since the positioning part 4 is provided with at least two groups, the other positioning parts 4 that have not entered the bottom of the drill bit can perform the loading and unloading operations of the metal round tube, thereby greatly saving the transition time required for loading and unloading, thereby improving production efficiency. After loading, the positioning part 4 performs preliminary positioning on the metal round tube, and when it is aligned with the top pressing part 5, it can be processed and positioned for the metal round tube by pressing and tightening at both ends. Since the position of the positioning part 4 is fixed, the positioning part 4 and the top pressing part 5 can also perform axial positioning on the two ends of the metal round tube, thereby ensuring that the axis position of each hole is constant. At the same time, since the clamping block 6 on the top pressing part 5 positions the side wall of the metal round tube, it can be based on the clamping of the two ends of the positioning part 4 and the top pressing part 5. The side wall position can also be auxiliary fixed, thereby further preventing the metal round tube from deviating during drilling.

[0034] Since the positioning part 4 also includes a positioning support plate 45 and a positioning plate 46, the position of the metal round tube can be more accurately determined by supporting the metal round tube and the laterally limiting the metal round tube. When drilling, the two sets of clamping blocks 6 clamp and fix the side walls of the metal round tube, which can better buffer the eccentric rotation pressure of the drill bit on the metal round tube. At this point, the positioning part 4 and the pressing part 5 can assist in pressing the two ends of the metal round tube for positioning. The reciprocating drive member 3 and the pressing drive member 54 both use the corresponding screw rod 2 and the motor 2 for driving the screw rod 2 to rotate to achieve reciprocation. The provision of the chip removal hole 48 and the waste chip groove 47 can ensure that there is no need to clean up the waste chips again during manual loading and unloading, which is also more time-saving and labor-saving.

Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents.
