Description

Technical Field

[0001] This utility model belongs to the field of machining, and specifically relates to a drilling device. Background Technology

[0002] In fields such as machining, drilling is a core process for achieving workpiece drilling, tapping, and other machining requirements. Its machining accuracy and efficiency directly affect the final product quality and production schedule.

[0003] Currently, the drilling equipment commonly found on the market is mainly divided into two categories: one is large bench drills, and the other is handheld portable drills.

[0004] Bench-type drilling machines have the advantages of good rigidity and high machining accuracy, but they are bulky and fixed in position. Their machining range is limited by the size of the worktable and the spindle travel. When dealing with large workpieces, non-standard sized workpieces, or when multi-station drilling is required at different positions on the workpiece, their flexibility is seriously insufficient.

[0005] While handheld portable drills offer advantages such as flexible operation and no need for fixed installation, they rely entirely on the operator's hand stability during drilling. Deviation and vibration can easily occur when the drill bit enters the workpiece, especially at the moment of penetration, resulting in inaccurate drilling position, rough hole walls, and difficulty in guaranteeing drilling quality.

[0006] Therefore, we propose a drilling device to solve the above problems. Utility Model Content

[0007] In view of the problems of handheld portable drills, which rely entirely on the operator's hand stability during drilling, and are prone to deviation and vibration at the moment of drill bit entry and especially the moment of exiting the workpiece, resulting in inaccurate drilling position, rough hole wall, and difficulty in guaranteeing drilling quality, this utility model provides a drilling device.

[0008] The solution adopted by this utility model to solve its technical problem is: a drilling device, including a base, a sliding seat, a linear drive mechanism, a main cantilever, an auxiliary cantilever, a vertical arm, a drilling power head, a handle, and a connecting assembly. A column is vertically fixed on the top of the base, the sliding seat is disposed on the side of the column, and the linear drive mechanism is fixedly installed on the side of the column and connected to the sliding seat for driving the sliding seat to move vertically up and down. One end of the main cantilever is rotatably connected to the sliding seat, and the other end is rotatably connected to the auxiliary cantilever. The vertical arm is fixed to the end of the auxiliary cantilever, and its inner cavity is provided with an extension rod. The bottom end of the extension rod passes through the bottom opening of the vertical arm and is detachably connected to the drilling power head through a connecting assembly.

[0009] Preferably, a guide rail is vertically fixed to the side of the column.

[0010] Preferably, the linear drive mechanism includes a threaded rod, a drive motor, and a slider. The threaded rod is rotatably mounted on the side of the column and is set corresponding to the sliding seat. The drive motor is fixedly mounted on the top of the column through a base, and its output shaft is connected to the upper end of the threaded rod. The slider is threadedly engaged with the threaded rod and slidably engaged with the guide rail. The slider is fixedly connected to the sliding seat.

[0011] Preferably, a groove is provided on one side of the vertical arm, and a handle is provided in the groove. One end of the handle passes through the groove and is fixedly connected to the upper end of the extension rod.

[0012] Preferably, the connecting assembly includes a fixing seat and a clamp, the fixing seat is fixedly installed at the bottom end of the extension rod, and the clamp is fixedly installed on the side of the fixing seat for connecting the drilling power head.

[0013] Preferably, a spring is fitted on the outer side of the extension rod, and the spring is installed between the top of the fixed seat and the bottom end of the vertical arm.

[0014] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model provides a stable mounting carrier for the drilling power head through a rigid support structure composed of a column, sliding seat, main cantilever, auxiliary cantilever and vertical arm, replacing manual hand operation and reducing positional deviation caused by hand tremors at the source. In addition, the sliding cooperation structure between the extension rod and the vertical arm, through the control handle, ensures that the up and down feed action of the drilling power head is stably carried out along the axis of the vertical arm, ensuring that the drilling power head always cuts into the workpiece in the preset vertical direction, avoiding tilting and deviation during the feed process, and improving drilling accuracy and processing quality.

[0015] 2. This utility model designs the main cantilever and auxiliary cantilever as rotatable, and sets a sliding extension rod inside the vertical arm. Combined with the handle control, it allows the operator to flexibly adjust the position of the drilling power head within a certain range to adapt to the drilling needs of different positions, thus taking into account both the stability of the bench drill and the flexibility of the handheld drill.

[0016] 3. By incorporating a spring, this utility model assists the worker in resetting the extension rod, fixed seat, and drilling power head upwards after drilling is completed, effectively reducing the operator's workload. Attached Figure Description

Detailed Implementation

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0020] Please see Figure 1-2 This utility model provides a technical solution for drilling equipment: Example 1: according to Figure 1 and Figure 2 As shown, it includes a base 1, a sliding seat 51, a linear drive mechanism, a main cantilever 55, an auxiliary cantilever 58, a vertical arm 61, a drilling power head 67, a handle 62, and connecting components. A column 2 is vertically fixed to the top of the base 1, and the sliding seat 51 is disposed on the side of the column 2. A guide rail 3 is vertically fixed to the side of the column 2, and the guide rail 3 is disposed inside the sliding seat 51.

[0021] The linear drive mechanism includes a threaded rod 42, a drive motor 41, and a slider 43. Bearing seats are respectively fitted at the upper and lower ends of the threaded rod 42. The two bearing seats are respectively installed on the left side of the column 2. The threaded rod 42 is supported by the two bearing seats to ensure the stability of the threaded rod 42 during rotation. The threaded rod 42 is set with a corresponding sliding seat 51.

[0022] The drive motor 41 is fixedly mounted on the top of the column 2 via the base 44. Its output shaft is connected to the upper end of the threaded rod 42 and is used to drive the threaded rod 42 to rotate in both directions. The slider 43 is threadedly engaged with the threaded rod 42 and slidably engaged with the guide rail 3. The slider 43 is fixedly connected to the sliding seat 51. The drive motor 41 drives the threaded rod 42 to rotate, and the threaded rod 42 drives the sliding seat 51 to move vertically up and down via the slider 43.

[0023] A joint seat 53 is welded and fixed to the left side of the sliding seat 51. A rib 52 is welded and fixed between the joint seat 53 and the sliding seat 51. An ear plate 54 is welded and fixed to one end of the main cantilever 55. The ear plate 54 is hinged to the joint seat 53 via a pin, allowing the main cantilever 55 to rotate manually. A joint seat 56 is welded and fixed to the other end of the main cantilever 55. An ear plate 57 is welded and fixed to one end of the auxiliary cantilever 58. The ear plate 57 is hinged to the joint seat 56 via a pin, allowing the auxiliary cantilever 58 to rotate manually. This allows the operator to flexibly adjust the angles of the main cantilever 55 and the auxiliary cantilever 58 within a certain range.

[0024] The vertical arm 61 is fixed to the other end of the auxiliary cantilever 58. An extension rod 63 is provided in its inner cavity. A sliding groove is provided on one side of the vertical arm 61. A handle 62 is provided in the sliding groove. One end of the handle 62 passes through the sliding groove and is fixedly connected to the upper end of the extension rod 63. The bottom end of the extension rod 63 extends out through the bottom opening of the vertical arm 61. The length of the extension rod 63 extending out of the vertical arm 61 is controlled by operating the handle 62.

[0025] The connecting assembly includes a fixed base 65 and a clamp 66. The fixed base 65 is fixedly installed at the bottom end of the extension rod 63, and the clamp 66 is fixedly installed on the side of the fixed base 65 for connecting the drilling power head 67. The drilling power head 67 is detachably assembled in the clamp 66. By operating the handle 62, the up and down feed motion of the drilling power head 67 is stably performed along the axis of the vertical arm 61, ensuring that the drilling power head 67 always cuts into the workpiece in the preset vertical direction, avoiding tilting and deviation during the feed process, and improving drilling accuracy and machining quality.

[0026] A spring 64 is sleeved on the outside of the extension rod 63. The spring 64 is installed between the top of the fixed seat 65 and the bottom of the vertical arm 61. After drilling is completed, the elastic force of the spring 64 can assist the worker to reset the extension rod 63, the fixed seat 65 and the drilling power head 67 upward, effectively reducing the operating burden.

[0027] In practical use, the drilling equipment of this utility model first requires the operator to hold the handle 62 and adjust the drilling power head 67 to the workpiece processing area by rotating the main cantilever 55 and the auxiliary cantilever 58. Next, the drive motor 41 is started by the control switch. The drive motor 41 drives the threaded rod 42 to rotate in the forward direction. The threaded rod 42 drives the sliding seat 51 to move vertically up and down through the slider 43, thereby driving the sliding seat 51, the main cantilever 55, the auxiliary cantilever 58, the vertical arm 61 and the drilling power head 67 to move down synchronously. The drilling power head 67 is adjusted to a suitable height. The drive motor 41 is then turned off to prepare for subsequent feed drilling. The operator holds the handle 62 and applies pressure steadily downward along the axis of the vertical arm 61, causing the extension rod 63 to extend from the bottom of the vertical arm 61 and drive the drill bit of the drilling power head 67 to cut into the workpiece. When the drilling reaches the predetermined depth, the operator stops applying pressure to the handle 62. At this time, the spring 64 is released, pushing the fixed seat 65 and the extension rod 63 upward, thereby causing the drilling power head 67 to rise and disengage from the workpiece hole. After the drill bit is completely withdrawn, the drilling power head 67 can be moved away again by manually adjusting the angles of the main cantilever 55 and the auxiliary cantilever 58, in preparation for the next operation.
