Description

Technical Field

[0001] The utility model relates to the technical field of wood processing equipment, in particular to a rolling pin drilling device. Background Art

[0002] There are several types of rolling pins, including single-hand rolling pins, double-hand rolling pins, olive rolling pins, flower rolling pins, walking hammers, etc. The double-hand rolling pin consists of a round rod and a shaft. A through hole is provided along the axial direction of the end face of the round rod. The shaft is passed through the hole, and both ends of the shaft are respectively located at both ends of the round rod. When the existing equipment drills holes in the round rod, it is necessary to manually hold the round rod, fix it on the fixture, and then use a drilling machine to drill holes from one end of the end face of the round rod, and then drill holes on the other side of the round rod until it communicates with the hole at one end of the round rod. In this way, not only is the efficiency low, but also the holes drilled on both end faces of the round rod may not have the same axial direction due to manual positioning, resulting in the shaft being unable to pass through the hole to form a rolling pin. Therefore, there is an urgent need for a rolling pin drilling device that can not only improve the drilling efficiency but also make the axial directions of the holes on both end faces coincide.

[0034] To describe in detail the technical content, achieved objectives and effects of the present utility model, the following is described in conjunction with the embodiments and with reference to the accompanying drawings.

[0035] Please refer to Figures 1 to 3 , a rolling pin drilling device, comprising:

[0036] A frame 1;

[0037] A feeding mechanism 2, the feeding mechanism 2 includes a first feeding channel 21 and a second feeding channel 22. The first feeding channel 21 and the second feeding channel 22 are arranged along the X direction and distributed on the frame 1. The first feeding channel 21 is inclined and connected to the frame 1, the second feeding channel 22 is parallel to the first feeding channel 21. The first feeding channel 21 is used to convey one end of a round bar, and the second feeding channel 22 is used to convey the other end of a round plate;

[0038] A material receiving device 3, the material receiving device 3 is connected to the frame 1 along the Y direction or the reverse Y direction. The material receiving device 3 is a limiting groove matching the round bar;

[0039] A first moving mechanism 4, the first moving mechanism 4 is used to drive the material receiving device 3 to move;

[0040] A drilling device, the drilling device is located on the reverse Y direction side of the material receiving device 3. The drilling device includes a first drilling machine 5 and a second drilling machine 6. The first drilling machine 5 moves along the X direction or the reverse X direction, the second drilling machine 6 moves along the X direction or the X direction. The drilling heads of the first drilling machine 5 and the second drilling machine 6 are axially coincident. The first drilling machine 5 and the second drilling machine 6 move towards each other. The height of the first drilling machine 5 and the second drilling machine 6 from the ground is the same as the height of the material receiving device 3 from the ground;

[0041] A second moving mechanism 7, the second moving mechanism 7 is used to drive the first drilling machine 5 and the second drilling machine 6 to move;

[0042] The first moving mechanism 4 and the second moving mechanism 7 drive the material receiving device 3 and the drilling device to switch between a first state and a second state;

[0043] The first state, the material receiving device 3 is located between the lower end of the first feeding channel 21 and the lower end of the second feeding channel 22;

[0044] The second state, the material receiving device 3 is located between the first drilling machine 5 and the second drilling machine 6.

[0045] In the above embodiments, in the first state, one end of the round bar is placed at the high end of the first feeding channel 21, and the other end of the round bar is placed at the high end of the second feeding channel 22. The round plate roller is placed on the limit groove. Then, the first moving mechanism 4 drives the material receiving device 3 to move in the reverse Y direction, so that the round bar of the material receiving device 3 is located between the first drilling machine 5 and the second drilling machine 6. Then, the second moving mechanism 7 drives the first drilling machine 5 and the second drilling machine 6 to move towards each other to drill the two end faces of the round bar until the first drilling machine 5 touches the second drilling machine 6, which indicates that the holes in the round bar have been penetrated. Then, the shaft is passed through the hole in the round plate to complete the assembly of the rolling pin. Compared with the prior art, it can not only improve the drilling efficiency, but also make the holes on the two end faces axially coincide.

[0046] As an alternative embodiment, the first moving mechanism 4 includes a first slider 42 and a first screw rod guide rail assembly 41. The first screw rod guide rail assembly 41 is connected to the frame 1. The axial direction of the first screw rod guide rail assembly 41 is the Y direction. The first slider 42 is slidably connected to the first screw rod guide rail assembly 41, and the material receiving device 3 is connected to the first slider 42.

[0047] In the above embodiments, by setting the first slider 42 and the first screw rod guide rail assembly 41, the material receiving device 3 can be stably switched between the first state and the second state, and then the round bar can be better drilled.

[0048] As an alternative embodiment, the second moving mechanism 7 includes a second screw rod shaft 71, a second slider 72, a third slider 73 and a driving motor. The second screw rod shaft 71 is connected to the frame 1. The second screw rod shaft 71 is divided into a first section 711 and a second section 712. The threads of the first section 711 and the second section 712 are opposite. The second slider 72 is slidably connected to the first section 711, and the second slider 72 is slidably connected to the second section 712. The driving motor is connected to the frame 1, and the driving motor is in transmission connection with the second screw rod shaft 71. The first drilling machine 5 is connected to the second slider 72, and the second drilling machine 6 is connected to the third slider 73.

[0049] In the above embodiments, when the first moving mechanism 4 drives the material receiving device 3 to move between the first drilling machine 5 and the second drilling machine 6, the driving motor is turned on to make the second slider 72 and the third slider 73 move in opposite directions, so that the first drilling machine 5 and the second drilling machine 6 move towards each other to drill the round plate.

[0050] As an alternative embodiment, the rolling pin drilling device further includes a first cylinder 8, a second cylinder 9, a first positioning plate 10 and a second positioning plate 11. The second slider 72 is provided with a through hole matching the first cylinder 8. The cylinder block of the first cylinder 8 is connected to the frame 1. The axial direction of the first cylinder 8 is the X direction. The first positioning plate 10 is connected to the piston rod of the first cylinder 8. The cylinder block of the second cylinder 9 is connected to the frame 1. The second cylinder 9 and the first cylinder 8 are symmetrically arranged with respect to the material receiving device 3. The second positioning plate 11 is connected to the piston rod of the second cylinder 9. The first positioning plate is provided with a first stepped hole 101. The diameter of the hole of the first stepped hole 101 facing the reverse direction of the X direction is smaller than the diameter of the first drilling machine 5. The diameter of the hole of the first stepped hole 101 facing the X direction has a clearance fit with one end of the round bar. The second positioning plate 11 is provided with a second stepped hole 102. The diameter of the hole of the second stepped hole 102 facing the X direction is smaller than the diameter of the second drilling machine 6. The diameter of the hole of the second stepped hole 102 facing the reverse direction of the X direction has a clearance fit with the other end of the round bar.

[0051] In the above embodiment, when the round bar is located between the first drilling machine 5 and the second drilling machine 6, the first cylinder 8 drives the first positioning plate 10 to match one end of the round bar with the first stepped hole 101. The second cylinder 9 drives the second positioning plate 11 to match the other end of the round plate with the second stepped hole 102, so that the round bar is fixed. Then, the second moving mechanism 7 drives the first drilling machine 5 and the second drilling machine 6 to move, so as to drill the round bar. By setting the first positioning plate 10 and the second positioning plate 11, during the drilling process, the round bar will not shake due to the vibration of the drilling machine, thus ensuring the axial coincidence of the holes at both ends of the round bar.

[0052] As an alternative embodiment, the height distance between the lower ends of the first feeding channel 21 and the second feeding channel 22 and the material receiving device 3 is 3 - 5 cm.

[0053] In the above embodiment, to avoid the height distance between the lower ends of the first feeding channel 21 and the second feeding channel 22 and the material receiving device 3 being too high, when the round bar falls into the limiting groove, there will be a resilience force, causing the round plate to be ejected from the limiting groove.

[0054] The above are only the embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. All equivalent transformations made by using the content of the specification and drawings of the present invention, or directly or indirectly applied in related technical fields, are equally included in the patent protection scope of the present invention.
