Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, specifically to an adjustable square hole drilling machine. Background Technology

[0002] When processing wooden products, a tenon and groove connection structure, known as mortise and tenon joint, is often used. The tenon is relatively easy to machine, while the groove is typically machined using mortise and groove cutting tools. Currently, square hole machines are also commonly used for machining mortises and grooves.

[0003] Existing square hole drilling machines have a simple structure. For example, the feed motion of the cutter is mostly manually controlled, which seriously affects the efficiency of mortise and tenon machining. Furthermore, the cutter angle cannot be adjusted, and the cutter can only move vertically, which poses significant limitations in mortise and tenon machining. Therefore, there is an urgent need to design an adjustable square hole drilling machine to solve these problems. Utility Model Content

Detailed Implementation

[0029] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-5 As shown in the figure, an adjustable square hole machine provided by this utility model includes a base 1, a mounting frame 2 fixedly mounted on the rear side of the base 1, a lifting assembly 3 mounted on the top of the base 1, and a worktable 5 mounted on the top of the lifting assembly 3; a rotating mechanism 7 is mounted on the top of the mounting frame 2, and a rotating mechanism 8 located above the worktable 5 is mounted on one side of the rotating mechanism 7, the rotating mechanism 7 being at least used to drive the rotating mechanism 8 to rotate; a guide rail 9 is mounted on the front of the rotating mechanism 8, and a grooving mechanism 10 is slidably mounted on the rotating mechanism 8 via the guide rail 9, the grooving mechanism 10 being at least used to groove the product; a transmission box 12 is mounted on the top of the rotating mechanism 8, and a drive mechanism 11 is mounted on one side of the transmission box 12, the drive mechanism 11 being at least used to drive the grooving mechanism 10 to reciprocate on the rotating mechanism 8 via the transmission box 12.

[0031] In this embodiment, a base 1 is included. The base 1 serves as a support component. Four downward protrusions are formed on the bottom of the base 1 to facilitate the placement of the base 1 on the ground. A mounting bracket 2 is fixedly installed on the rear side of the base 1. The mounting bracket 2 is an H-shaped structure and is made of steel.

[0032] In this embodiment, a lifting assembly 3 is provided on the top of the base 1;

[0033] Specifically, the lifting assembly 3 includes a bushing 31 fixed to the top outer wall of the base 1, and a lead screw 32 is provided inside the top of the bushing 31. A lead screw sleeve 34 is threaded onto the top of the lead screw 32, and a positioning wheel 33 is threaded onto the external thread of the lead screw 32. The top of the lead screw sleeve 34 is installed at the bottom of the worktable 5. A transmission structure is provided below the worktable 5. The movement of the transmission structure drives the lead screw sleeve 34 to rotate. Under the action of the lead screw sleeve 34 and the lead screw 32, the relative length of the two is changed, so as to adjust the height of the worktable 5. After the height adjustment is completed, the positioning wheel 33 is rotated and abuts against the lower surface of the lead screw sleeve 35 to fix the lead screw sleeve 34 and the lead screw 32.

[0034] In this embodiment, a workbench 5 is installed on the top of the lifting assembly 3, and the workbench 5 serves as a platform for product installation.

[0035] In this embodiment, a follower component 4 is provided between the base 1 and the worktable 5;

[0036] Specifically, the follower component 4 includes a movable frame 41 fixedly connected to the worktable 5 and a fixed frame 42 fixedly connected to the base 1. A locking bolt 43 is provided between the movable frame 41 and the fixed frame 42. When the height of the worktable 5 is adjusted, the operator needs to loosen the locking bolt 43 first so that the movable frame 41 can slide along the fixed frame 42. After the worktable 5 is adjusted, the locking bolt 43 is used again to lock the movable frame 41 and the fixed frame 42.

[0037] In this embodiment, a clamping mechanism 6 is provided on the top of the workbench 5;

[0038] Specifically, the clamping mechanism 6 includes a cylinder 61 fixedly installed on the outer wall of one side of the top of the workbench 5, and an air valve 62 is provided on the outer wall of the top of the cylinder 61. A movable plate 63 is installed on the output rod of the cylinder 61. A fixed plate 64 is fixedly installed on the back side of the top of the workbench 5, and a protective sleeve 65 is provided on the fixed plate 64. The operator places the product on the workbench 5 between the fixed plate 64 and the movable plate 63. The air source enters the air valve 62, and the cylinder 61 is activated, which drives the movable plate 63 to move quickly toward the fixed plate 64, thereby achieving the fixed clamping of the product and the fixed installation of the product above the workbench 5.

[0039] In this embodiment, a rotating mechanism 7 is provided on the top of the mounting bracket 2;

[0040] Specifically, the rotating mechanism 7 includes fixed seats 71 fixedly mounted on both sides of the top of the mounting bracket 2, and a rotating seat 72 is provided between the two fixed seats 71. The rotating seat 72 is rotatably connected to the fixed seats 71 via a shaft. Both sides of the fixed seats 71 are provided with arc-shaped sliding grooves 75. The rotating seat 72 is provided with a locking screw 76 that passes through the sliding groove 75. When it is desired to adjust the pitch angle of the grooving mechanism 10, the operator can first loosen the locking screw 76, so that the rotating seat 72 rotates within the two fixed seats 71 via the shaft. At the same time, the locking screw 76 moves with the rotating seat 72 within the sliding groove 75. After the angle of the rotating seat 72 reaches the specified value, the locking screw 76 is used to lock the rotating seat 72 on the fixed seat 71.

[0041] Specifically, a pointer 74 is fixedly installed on the outer wall of the top of the fixed base 71, and a scale 73 that cooperates with the pointer 74 is installed on the top of the rotating base 72. When adjusting the pitch angle of the rotating base 72, the operator can refer to the indications on the pointer 74 and the scale 73. Since the scale 73 rotates synchronously with the rotating base 72, while the pointer 74 is stationary, the rotating disk 81, the slotting mechanism 10, the drive mechanism 11 and the transmission box 12 all move along with the rotating base 72.

[0042] In this embodiment, a rotating mechanism 8 is provided on one side of the rotating mechanism 7, located above the worktable 5. The rotating mechanism 7 is at least used to drive the rotating mechanism 8 to rotate.

[0043] Specifically, the rotating mechanism 2 8 includes a rotating disk 81 rotatably connected to the outer wall of the front of the rotating seat 72 via a shaft. Locking screws 2 82 penetrating the rotating disk 81 are provided on the outer walls of both sides of the front of the rotating seat 72. A mounting platform 83 slidably connected to the guide rail 9 is provided on the front of the rotating disk 81. The grooving mechanism 10 is mounted on the mounting platform 83. The adjustment method of the rotating mechanism 2 8 is similar to that of the rotating mechanism 1 7. The left and right angles of the grooving mechanism 10 are adjusted by the rotating mechanism 2 8. First, the locking screws 2 83 are loosened, and then the rotating disk 81 rotates along the rotating seat 71. After the adjustment is completed, the locking screws 2 82 are fixed. While the rotating disk 81 rotates, the grooving mechanism 10, the drive mechanism 11, and the transmission box 12 all move accordingly.

[0044] In this embodiment, a guide rail 9 is provided on the front side of the rotating mechanism 2 8, and a grooving mechanism 10 is slidably provided on the rotating mechanism 2 8 via the guide rail 9. The grooving mechanism 10 is at least used for grooving the product.

[0045] Specifically, the grooving mechanism 10 includes a drive motor 101, a tool holder 104 at the bottom of the drive motor 101, and a twist drill 105 connected to the drive motor 101 inside the tool holder 104. A grooving cutter 106 mounted on the bottom outer wall of the drive motor 101 is sleeved on the outside of the twist drill 105. The twist drill 105 and the grooving cutter 106 work together. The drive motor 101 can drive the twist drill 105 to rotate at high speed to drill holes in the product and remove chips. When the drive mechanism 11 drives the grooving mechanism 10 to move downward through the transmission box 12, the grooving cutter 106 can perform square hole processing on the product. The two work together to quickly achieve square hole processing on the product.

[0046] A vacuum cleaner 102 is installed on the top of the drive motor 101, and a suction pipe 103 is installed on the vacuum cleaner 102. The bottom end of the suction pipe 103 is located below the tool holder 104. When the product is grooved using the twist drill 105 and the grooving tool 106, the vacuum cleaner 102 is started, and the suction pipe 103 can absorb the debris in time, ensuring the cleanliness of the processing environment.

[0047] In this embodiment, a transmission box 12 is provided on the top of the rotating mechanism 2 8, and a driving mechanism 11 is provided on one side of the transmission box 12. The driving mechanism 11 is at least used to drive the slotting mechanism 10 to reciprocate on the rotating mechanism 2 8 through the transmission box 12.

[0048] In this embodiment, a foot switch 13 is also included, which enables the start and stop of the drive mechanism 11 and the slotting mechanism 10.

[0049] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
