DETAILED DESCRIPTION

[0024] See also Figure 1 The utility model provides a horizontal center hole drilling machine, including a material discharging rack 1, a positioning clamping disk 3, a drilling machine 4 and a first position adjustment mechanism 6; the drilling machine 4 and the positioning clamping disk 3 are fixedly arranged on the material discharging rack 1; the drilling axis of the drilling machine 4 is aligned with the center point of the positioning clamping disk 3; the first position adjustment mechanism 6 is arranged on the material discharging rack 1; the workpiece 7 to be drilled is placed on the material discharging rack 1 and rolled along the X direction of the material discharging rack 1 into the first position adjustment mechanism 6; the first position adjustment mechanism 6 drives the workpiece 7 to be drilled to move along the Y direction of the material discharging rack 1 and extends the workpiece 7 to be drilled toward the positioning clamping disk 3. The material discharging rack 1 can hang multiple workpieces 7 to be drilled at one time (such as Figure 5), reducing the need for auxiliary lifting for each piece; the positioning clamping disc 3 uses a self-centering three-jaw chuck for simultaneous positioning and clamping. The drilling machine 4 is equipped with a self-locking drill clamp to clamp the center drill bit for drilling. The workpiece 7 to be drilled is rolled so that it falls directly into the first position adjustment mechanism 6. The first position adjustment mechanism 6 moves the workpiece 7 along the Y direction of the material rack 1 and ultimately extends it into the positioning clamping disc 3. After the positioning clamping disc 3 is locked, the drilling axis of the drilling machine 4 is aligned with the center point of the positioning clamping disc 3. Therefore, the drilling machine 4 can be used to create a top hole at the end of the workpiece 7 to be drilled. During operation, the present invention directly rolls the workpiece 7 to be drilled and utilizes the first position adjustment mechanism 6 to move it in the Y direction, thereby reducing labor intensity. At the same time, after the drilling machine 4 completes the hole drilling, the drilled workpiece 8 is directly pushed out of the first position adjustment mechanism 6, and the end hole of the next workpiece 7 to be drilled can be drilled, thereby greatly shortening the processing time. The end hole drilling operation of batches of workpieces 7 to be drilled can be completed in a short time, thereby improving work efficiency.

[0025] Among them, see Figure 1 as well as Figure 4 The first position adjustment mechanism 6 employed in the present invention includes a linear movable shaft 61 and a support seat 63. The linear movable shaft 61 is movably mounted on the material rack 1 along the Y direction of the material rack 1. The support seat 63 is fixedly mounted on the linear movable shaft 61. The upper surface of the support seat 63 is coplanar with the upper surface of the material rack 1. The part to be drilled 7 rolls along the X direction of the material rack 1 into the support seat 63. The linear movable shaft 61 drives the part to be drilled 7 to move along the Y direction of the material rack 1 and extends the part to be drilled 7 toward the positioning clamping disk 3. There are at least two groups of support seats 63, and the two groups of support seats 63 are mounted on the linear movable shaft 61 along the axial direction of the linear movable shaft 61. The first position adjustment mechanism 6 also includes a pair of support claws 64 mounted on the support seats 63. The two support claws 64 are non-contact and parallel. The upper surfaces of the support claws 64 are coplanar with the upper surface of the material rack 1. The part to be drilled 7 rolls along the X direction of the material rack 1 into the support claws 64. The cross section of the supporting claw 64 can be circular, elliptical, etc. As long as it can lift the drilling member 7, the shape of the cross section can be arbitrary, and the present invention does not limit or restrict it.

[0026] See also Figure 4In order to conveniently push out the drilled part 8 on the supporting claw 64, the first position adjustment mechanism 6 provided by the utility model also includes a clamping mechanism; the clamping mechanism includes a chuck 65, a pin and a connecting rod; the chuck 65 is set on the material rack 1 through the pin and rotates along the axial direction of the pin; the chuck 65 is sickle-shaped as a whole; the connecting rod is connected to the chuck 65 and drives the chuck 65 to be suspended on the support seat 63 or detached from the support seat 63. When the hole at the end of the part to be drilled 7 is completed, the drilled part 8 has been formed. The connecting rod can be moved to drive the chuck 65 to disengage from the support seat 63. At this time, the support seat 63 is gently pushed to make the linear movable shaft 61 connected to the support seat 63 rotate around the axis of the linear movable shaft 61. At this time, the drilled part 8 on the support seat 63 slides directly out of the support seat 63 under the action of gravity. After that, the support seat 63 is reset, and the connecting rod is moved to drive the chuck 65 to be suspended on the support seat 63, completing the clamping effect of the first position adjustment mechanism 6, so that its position or posture is stable, which is convenient for drilling the end of the next part to be drilled 7.

[0027] In addition, the first position adjustment mechanism 6 provided by the present invention further includes a guide sleeve 62 provided on the unloading rack 1 ; the linear movable shaft 61 is placed in the guide sleeve 62 and moves freely along the axial direction of the guide sleeve 62 .

[0028] See also Figure 1 as well as Figure 2 The horizontal center hole drilling machine provided by the present invention also includes a second position adjustment mechanism 5 provided on the discharge rack 1; along the rolling direction of the workpiece 7 to be drilled, the second position adjustment mechanism 5 and the first position adjustment mechanism 6 are arranged in sequence from front to back; the second position adjustment mechanism 5 drives the workpiece 7 to be drilled to move along the Y direction of the discharge rack 1; the upper surface of the second position adjustment mechanism 5 and the upper surface of the discharge rack 1 are in the same plane. Generally speaking, when the workpiece 7 to be drilled rolls along the discharge rack 1, it may not move in the strict X direction, and there may be a certain amount of offset. Therefore, it is necessary to first position the workpiece 7 to be drilled by the second position adjustment mechanism 5, that is, when the workpiece 7 to be drilled falls into the second position adjustment mechanism 5, the second position adjustment mechanism 5 drives the workpiece 7 to be drilled to move along the Y direction of the discharge rack 1. At this time, it is equivalent to completing the position correction or rough adjustment of the workpiece 7 to be drilled, so that it can smoothly roll into the first position adjustment mechanism 6 and carry out subsequent work.

[0029] See also Figure 2 as well as Figure 3The second position adjustment mechanism 5 includes a trough 51 extending along the Y-axis of the unwinding frame 1. Multiple V-shaped pulleys 53 are arranged in parallel within the trough 51. The V-shaped pulleys 53 drive the workpiece 7 to be drilled along the Y-axis of the unwinding frame 1. The tops of the V-shaped pulleys 53 are flush with the upper surface of the unwinding frame 1. The second position adjustment mechanism 5 also includes rotating shafts 52. The number of rotating shafts 52 matches the number of V-shaped pulleys 53. The V-shaped pulleys 53 are movably mounted within the trough 51 via the rotating shafts 52. The V-shaped pulleys 53 rotate axially about the rotating shafts 52.

[0030] See also Figure 1 as well as Figure 5 To facilitate the collection of drilled parts 8, the horizontal center hole drilling machine provided by the present invention also includes a receiving rack 2 located at the bottom of the first position adjustment mechanism 6 and connected to the unloading rack 1. The receiving rack 2 can directly store multiple drilled parts 8 at a time. The receiving rack 2 is connected to the unloading rack 1 via a ramp, which allows the drilled parts 8 to slowly roll along the ramp into the receiving rack 2, preventing damage to the drilled parts 8 or accidental injury to workers due to the free fall of the drilled parts 8.

[0031] See also Figure 5 When the utility model is used, workers do not need to lift the workpieces to be drilled 7. They can use a lifting rope to hang multiple workpieces to be drilled 7 on the unloading rack 1 (a lot of workpieces to be drilled 7 can be placed at a time, depending on how much can be placed on the unloading rack 1). They can roll the workpieces to be drilled 7 onto the V-shaped pulley 53 of the second position adjustment mechanism 5 by hand, adjust the Y-direction position of the workpieces to be drilled 7 on the unloading rack 1 through the V-shaped pulley 53, and then roll the workpieces to be drilled 7 onto the supporting claw 64 of the first position adjustment mechanism 6. The linear moving shaft 61 is moved along the Y-direction of the unloading rack 1, and after being clamped by the positioning clamping disk 3, the top hole of the end of the workpiece to be drilled 7 is completed through the drilling machine 4. After the drilling operation is completed, the linkage rod is toggled to cause the linkage rod to drive the chuck 65 to disengage from the support seat 63. At this time, the support seat 63 is gently pushed, causing the linear movable shaft 61 connected to the support seat 63 to rotate about the axis of the linear movable shaft 61. At this time, the drilled part 8 on the support seat 63 slides directly off the support seat 63 under the action of gravity, completing the processing process. After the support seat 63 is reset, the linkage rod is toggled to cause the linkage rod to drive the chuck 65 to suspend on the support seat 63, completing the clamping function of the first position adjustment mechanism 6, stabilizing its position or posture, facilitating the drilling of the end of the next part 7 to be drilled, and achieving continuous processing.

[0032] In order to verify the practical effects of the horizontal center hole drilling machine provided by this utility model, a series of experiments were conducted. The experimental results show that after using the horizontal center hole drilling machine provided by this utility model, the time comparison is significantly improved, and the processing accuracy is also significantly improved. While saving production input costs, it greatly reduces the labor intensity of workers and significantly reduces machine tool wear, which fully demonstrates the effectiveness and superiority of this design.
