Description

Technical Field

[0001] The utility model relates to a bench drill, in particular to a lifting type laser positioning bench drill. Background Art

[0002] Existing bench drill structures with beam positioning functions, such as a Chinese invention patent with publication number CN106914649A, disclose a beam positioning device for a bench drill, whose main structure includes a main head and a drill bit. Laser lamp covers are respectively installed on both sides of the main head, a laser lamp holder is installed inside the laser lamp cover, and a laser lamp is installed in the laser lamp holder.

[0003] During actual use of the above-mentioned bench drill structure, two laser lamps are provided in the laser lamp holder. The two lasers are respectively arranged on both sides of the drill bit. The plane light beam emitted by the laser lamp forms an intersection point which falls on the center line of the drill bit. Accurate drilling can be achieved by simply placing the workpiece to be processed at the intersection point of the light beam.

[0004] However, due to the special use environment of the bench drill, when the drill bit drills a hole in the workpiece, the debris of the workpiece will splash. The splashing debris will hit the outer wall of the laser lamp cover. In severe cases, it will damage the laser lamp cover and affect the actual use of the laser lamp. Utility Model Content

[0008] Through the above technical solution, before processing the workpiece, the driving part drives the positioning frame to move downward, and the lasers emitted by the two laser lamps in the laser transmitter hit the workpiece mounting table. The workpiece is placed on the workpiece mounting table according to the position of the intersection marked by the laser. After the workpiece is installed, the driving part drives the positioning frame to move upward, and the distance between the laser transmitter in the positioning frame and the workpiece mounting table becomes larger; when the drill bit drills the workpiece on the workpiece mounting table, the possibility of the drilled debris on the workpiece contacting the laser positioning component can be minimized, and the laser positioning component can be protected to the greatest extent.

[0016] Preferably, a driving inclined block is provided at the lower end of the positioning frame;

[0017] When the positioning frame moves downward, the driving inclined block can press the blocking plate, and the blocking plate overcomes the elastic force of the elastic member and moves into the sliding groove.

DETAILED DESCRIPTION

[0032] The specific implementation modes of the present invention are further described below in conjunction with the accompanying drawings to make the technical solutions of the present invention easier to understand and grasp.

[0033] A lifting laser positioning bench drill, see Figure 1 , including a frame 1, on which a workpiece mounting table 2 and a machine head 3 are mounted, the workpiece mounting table 2 is located below the machine head 3, and a drill bit 4 is mounted on the machine head 3; the workpiece to be processed is mounted on the workpiece mounting table 2, and the drill bit 4 on the machine head 3 can perform drilling processing on the workpiece on the workpiece mounting table 2.

[0034] See also Figure 3 as well as Figure 4 A laser positioning component 6 is also provided on the machine head 3, and the laser positioning component 6 can emit corresponding lasers.

[0035] Regarding the laser positioning assembly, in this embodiment, the laser positioning assembly 6 includes a laser emitter 62, and the laser emitter 62 includes two laser lamps 621. The basic conditions of the installation of the two laser lamps 621 are as follows: Figure 5 As shown, the laser emission direction of each laser lamp 621 is oblique to the upper surface of the workpiece mounting table 2; Figure 6 As shown, the lower laser emitting ends of the two laser lamps 621 are tilted inward. With such a configuration, the light beams emitted by the two laser lamps 621 can form a cross, and the intersection formed by the intersection lines of the light beams is the location of the actual drilling of the drill bit. In addition, the intersection formed by the two laser lamps 621 is a common prior art and will not be described here. The laser is hit on the workpiece mounting table 2, and a laser marking point is formed on the workpiece mounting table 2. The operator only needs to mount the workpiece on the corresponding laser marking point on the workpiece mounting table 2, and the drill bit 4 on the machine head 3 can perform precise drilling processing on the workpiece on the workpiece mounting table 2.

[0036] See also Figure 3 as well as Figure 4 The machine head 3 is provided with a mounting groove 7 , and the laser positioning assembly 6 includes a positioning frame 61 , in which a laser emitter 62 is installed. The positioning frame 61 is vertically slidably connected in the mounting groove 7 .

[0037] See also Figure 3 as well as Figure 4 A driving member 5 is also provided in the machine head 3, and the driving member 5 is mainly used to drive the positioning frame 61 to move up and down. When the driving member 5 drives the positioning frame 61 to move upward, the lower end of the positioning frame 61 is preferably moved into the mounting groove 7.

[0038] Among them, see Figure 3 as well as Figure 4 The driving member 5 comprises a driving motor 51 mounted on the machine head 3, a driving gear 52 is mounted on the motor shaft of the driving motor 51, a driving rack 53 is mounted on the outer frame wall of the positioning frame 61, and the driving gear 52 and the driving rack 53 are meshed with each other, thereby driving the entire positioning frame 61 to move vertically up and down along the mounting groove 7. The driving motor 51 is preferably a stepping motor, so that the lifting height of the entire positioning frame 61 can be accurately controlled.

[0039] See also Figure 4 A sliding groove 8 is provided on the vertical groove wall of the installation groove 7, and a blocking plate 9 is slidably connected in the sliding groove 8. The sliding direction of the blocking plate 9 is perpendicular to the sliding direction of the positioning frame 61.

[0040] See also Figure 4 An elastic member 12 is also provided in the slide groove 8. The elastic member 12 is preferably a spring. The elastic force of the elastic member 12 is applied to the blocking plate 9. When the lower end of the positioning frame 61 moves into the mounting groove 7, the elastic member 12 drives the blocking plate 9 to block at the lower notch of the mounting groove 7.

[0041] See also Figure 2 as well as Figure 4 In order to realize automatic opening of the blocking plate 9, a protrusion 10 is provided at the end of the blocking plate 9 away from the elastic member 12. When the protrusion 10 abuts against the wall of the installation groove 7, a gap 15 is formed between the end of the blocking plate 9 away from the elastic member 12 and the wall of the installation groove 7.

[0042] See also Figure 2 as well as Figure 4A driving inclined block 13 is provided at the lower end of the positioning frame 61, and a driving inclined surface 14 is provided on the driving inclined block 13. When the positioning frame 61 moves downward, the driving inclined block 13 is inserted into the gap 15, and the driving inclined surface 14 on the driving inclined block 13 gradually abuts against the end of the blocking plate 9, so that the blocking plate 9 overcomes the elastic force of the elastic member 12 and moves into the slide groove 8.

[0043] See also Figure 4 A rubber block 11 is disposed on the protrusion 10 , and the rubber block 11 can abut against the groove wall of the installation groove 7 , thereby reducing the impact damage between the protrusion 10 and the groove wall of the installation groove 7 .

[0044] In actual use:

[0045] The driving member 5 drives the positioning frame 61 to move downward, and the end of the driving bevel block 13 is inserted into the interval 15. As the positioning frame 61 continues to move downward, the driving bevel 14 gradually acts on the blocking plate 9, and the blocking plate 9 overcomes the elastic force of the elastic member 12 and moves into the slide groove 8. The laser positioning component 6 protrudes from the outer position of the lower notch of the mounting groove 7. The laser emitted by the laser positioning component 6 will irradiate the workpiece mounting table 2. The positioning frame 61 moves downward to a specified height, and the laser marking point formed by the irradiation of the two laser lamps 621 can be formed on the workpiece mounting table 2. The operator can install the workpiece to be processed at the specified position of the workpiece mounting table 2 according to the position of the laser marking point.

[0046] After the workpiece to be processed is stably installed on the workpiece mounting table 2, the driving member 5 drives the positioning frame 61 to move upward in the reverse direction, driving the end of the inclined block 13 to gradually move out of the gap 15. As the driving frame continues to move upward, the elastic force of the elastic member 12 acts on the blocking plate 9, and the blocking plate 9 can be gradually moved out of the slide groove 8 until the positioning frame 61 is completely moved into the mounting groove 7. The blocking plate 9 acted upon by the elastic member 12 will be completely blocked at the notch position of the mounting groove 7.

[0047] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
