Description

Drilling machine lifting device

The invention relates to a processing machine, in particular to a lifting device for a drilling machine.

For example, the Republic of China Certificate No. M459043 patent application and the publication No. 201249570 patent application show that a general drilling machine includes a base, a guide post fixed to the base, a head mounted on the top of the guide post, and an adjustable height. And a sliding seat mounted between the head and the base, an adjusting unit mounted on the sliding seat, a locking unit mounted on the sliding seat, and a working platform connected to the sliding seat, the guiding column has a guiding column An axially extending row of teeth, the adjustment unit has a gear set that meshes with the row of teeth of the guide post and a handle that drives the rotation of the gear set.

When the use height of the table connected to the carriage is to be adjusted, the operator first loosens the lock unit. Then, the operator rotates the handle again, and by using the gear set to engage the tooth row of the guide post, the slider can be adjusted to move relative to the guide post, and after the positioning is adjusted, the locking unit is tightened.

In the above adjustment process, although the table can be supported by the tooth row to prevent the workbench from being dangerous due to the weight loss, It is cumbersome, time consuming and laborious to operate.

Accordingly, it is an object of the present invention to provide a lifting device for a drill press which is easy and labor-saving in ensuring adjustment of components.

Therefore, the lifting device of the drilling machine of the present invention comprises a base, a guiding rod, a working unit, an elastic member and a head unit. The guiding rod is disposed in the longitudinal direction and is connected to the base. The working unit has a working portion disposed above the base, a sleeve connected to the working portion and slidably sleeved on the guiding rod, and a sleeve a locking member for tensioning or releasing the sleeve relative to the guiding rod, the elastic member is sleeved on the guiding rod, and is disposed between the base and the sleeve member, and the elastic force thereof is constant The fitting is kept away from the base, and the head unit is disposed at the top of the guiding rod and disposed above the working portion.

The utility model has the advantages that the elastic member is sleeved on the guiding rod and is disposed between the base and the fitting member, so that the working portion can generate a safe lifting adjustment, and the adjusting operation is relatively easy, fast and labor-saving. .

The other features and advantages of the present invention will be apparent from the following detailed description of the embodiments of the present invention. FIG. 1 is a front perspective view of an embodiment of the lifting device of the drilling machine of the present invention; A rear view stereo combination diagram of one of the above embodiments of the present invention.

Referring to Figures 1 and 2, one of the lifting devices of the drilling machine of the present invention is The embodiment includes a base 10, a guide rod 20, a working unit 30, an elastic member 40, and a head unit 50 disposed on the top of the guide rod 20.

The base 10 has a base portion 11 and a stud 12 protruding from the base portion 11.

The guiding rod 20 is longitudinally disposed and fixed in the stud 12 of the base 10.

The work unit 30 has a working portion 31 disposed above the base 10, a sleeve portion 32 coupled to the working portion 31 and slidably sleeved on the guide rod 20, and a sleeve portion 32 opposite to the sleeve portion 32. The guide rod 20 produces a locking member 33 that is tightly positioned or released.

The elastic member 40 is sleeved on the guide rod 20 and disposed between the base 10 and the sleeve portion 32. The elastic force thereof keeps the sleeve portion 32 away from the base 10 . The elastic member 40 of the present embodiment adopts a compression spring and is sleeved on the outside of the guide rod 20 and has a bottom end 41 that abuts against the top end surface of the protrusion 12 and a bottom end surface of the sleeve member 32. Top 42.

The head unit 50 is disposed on the top of the guiding rod 20 and disposed above the working portion 31.

As shown in FIG. 1 , when the overall assembly of the drilling machine is completed, the head unit 50 is disposed above the working portion 31 of the working unit 30 , and the tool mounted by the head unit 50 can be fixed to the working portion 31 . The workpiece (not shown) is processed.

When the workpieces of different sizes are matched and the height of the working unit 30 is to be adjusted, the operator can first operate the locking member 33 and release the fitting member 32 relative to the guiding rod 20. At this time, the elastic member is utilized. 40 elastic The working unit 30 can be elastically biased upwards and can resist the self-weight of the working unit 30 to prevent the working unit 30 from falling down at random, and the operator can press the working portion 31 downward until the working portion 31 is adjusted to the desired height, and the fitting member 32 is slid relative to the guide rod 20 during adjustment. Finally, the locking member 33 is operated again, and the fitting member 32 is tightened and positioned relative to the guiding rod 20, so as to achieve the purpose of adjusting the working height of the working unit 30 without a step.

In the process of adjusting the working unit 30, the sleeve member 32 is slidably sleeved on the guiding rod 20, and the elastic force of the elastic member 40 makes the adjustment operation relatively stable. When the working unit 30 is performing the lifting and lowering adjustment, the working unit 30 can be biased upward by the elastic force of the elastic member 40, and the operator only needs to hold the working unit 30 by hand, and the working unit 30 can be avoided. It is dangerous because of its own weight loss, so it is safer and labor-saving during operation, and it is quite fast and time-saving.

Moreover, the slidable sleeve is generated by the sleeve member 32 and the guide rod 20. When the locking member 33 is operated and the sleeve member 32 is released from the guide rod 20, the working unit 30 can be operated. The guide rod 20 is pivoted to adjust the horizontal position of the working unit 30, and the relative position of the working unit 30 and the head unit 50 can be adjusted.

In summary, the constituent elements of the present invention are relatively simple, and the manufacturing assembly is relatively easy, and the lifting adjustment of the working unit 30 can be made safer and less laborious, so that the object of the present invention can be achieved.

However, the above is only an embodiment of the present invention, and the scope of the present invention cannot be limited thereto, that is, the application according to the present invention is The simple equivalent changes and modifications made by the scope of the patent and the contents of the patent specification are still within the scope of the invention.
