Description

Technical Field

[0001] The utility model belongs to the field of drilling machine processing and manufacturing, and specifically relates to a drill stopper installation tool. Background Art

[0002] A drilling machine is a general term for machines and equipment that use a tool that is harder and sharper than the target object to leave a cylindrical hole or hole on the target object by means of rotary cutting or rotary extrusion. In the process of installing the drill bit on the drilling machine, the length of the drill bit exposed outside the drilling machine needs to be precisely controlled to ensure that the depth of the holes drilled by different drill bits and different drilling machines when processing workpieces is the same. And if the length of the drill bit exposed outside the drilling machine is too long, the drilling machine will recognize that the drill bit is too long and is not suitable. If the length of the drill bit exposed outside the drilling machine is too short, the drilling machine will recognize that the drill is broken and cannot process the workpiece. How to accurately control the length of the drill bit exposed outside the drilling machine is still a technical problem that needs to be solved. Utility Model Content

[0003] In order to overcome the above-mentioned shortcomings, the purpose of the utility model is to provide a drill stopper installation tool, which limits the length of the drill bit exposed outside the drilling machine by installing a stopper on the drill bit, so as to ensure that the depth of holes drilled by different drilling machines and different drill bits when processing workpieces is the same.

The position of the limiting ring is limited by the setting of the fixing mechanism so that the drill bit passes through the limiting ring.

[0010] Furthermore, the dial indicator includes a measuring head and a dial, the diameter of the second through hole is larger than the diameter of the measuring head, at least a partial area of ​​the measuring head is accommodated in the second through hole, and during the downward pressing of the drill bit, one end of the drill bit can press down the measuring head, and then the downward pressing height is detected by the dial indicator. Since the position of the limit ring is fixed and the downward pressing height is accurately detected, the length of the drilling portion located below the limit ring can be accurately controlled.

[0011] Furthermore, the pressing mechanism includes a fixing seat, which is used to be detachably connected to the fixing plate. The fixing seat is an arch-shaped structure, one end of which is a hinged end hinged to the handle, and the other end is a limiting end.

[0012] Furthermore, a guide hole is provided on the limit end, and the pressing rod passes through the guide hole, and the pressing rod can move along the guide hole. By setting the guide hole, the movement track of the pressing rod is limited, so that the pressing rod can accurately press down the drill bit.

[0013] Furthermore, one end of the handle is hinged to the hinged end, and a bending portion is arranged in the middle of the handle, and the bending portion is arranged close to the hinged end, so that the handle is a labor-saving lever, which is convenient for pressing down operation, and the pressing path of the handle is expanded, making it easier to control the pressing accuracy.

[0014] Furthermore, the pressing mechanism further comprises a hinge, one end of which is hinged to the connecting end of the pressing rod, and the other end of which is hinged to the bending portion of the handle.

In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0028] See attached Figure 1-4 As shown, in the present application, a limit ring 5 is installed on the drill bit 6, and the drill bit 6 is divided into a connection part 61 and a drilling part 62 by the limit ring 5. The drill bit 6 on one side of the limit ring 5 is the connection part 61, and the connection part 61 is used to connect with the drilling machine, and the drilling machine can abut against the limit ring 5 when connected to the connection part 61; the drill bit 6 on the other side of the limit ring 5 is the drilling part 62, which is used to pin the workpiece. The length of the drilling part 62 is limited by the specific part where the limit ring 5 and the drill bit 6 are connected. The length of the drilling part is the length of the drill hole exposed outside the drilling machine, and the length of the drilling part is the depth of the drill hole. By accurately controlling the length of the drilling part 62, it is ensured that the drilling machine detects that the drill bit 6 is qualified and the depth of the hole drilled by the drilling part 62 is consistent.

[0029] In order to ensure that the length of the drilling portion 62 is accurately controlled when the drill bit 6 is installed with the limit ring 5, the present application discloses a drill stopper installation tool for limiting the length of the drilling portion 62. The installation tool includes a fixing plate 1, which is vertically arranged. A fixing mechanism 3 is arranged on the fixing plate 1 for fixing the limit ring 5 and the drill bit 6. A pressing mechanism 2 is arranged directly above the fixing mechanism 3. The pressing mechanism 2 is used to press down the drill bit 6. The drill bit 6 passes through the limit ring 5 so that the limit ring 5 is sleeved on the drill bit 6. A dial indicator 4 is arranged below the fixing mechanism 3 for detecting the pressing height of the drill bit 6.

[0030] In some embodiments, the fixing mechanism 3 includes a first through hole 31 and a second through hole 32 which are coaxially arranged. The first through hole 31 is located above the second through hole 32, and the diameter of the first through hole 31 is larger than the diameter of the first through hole 31. An annular boss 33 is formed at the connection between the first through hole 31 and the second through hole 32. The boss 33 is used to support the stop ring 5 in the vertical direction, and the inner wall of the first through hole 31 limits the horizontal position of the stop ring 5. During operation, the stop ring 5 is placed in the first through hole 31, the diameter of the first through hole 31 is not less than the diameter of the stop ring 5, the stop ring 5 is placed on the boss 33 along the first through hole 31, and then the drill bit 6 is placed in the through hole of the center part of the stop ring 5, and the drill bit 6 is pressed down by the pressing structure, and the drill bit 6 enters the second through hole 32 through the rear drilling part 62 of the stop ring 5, so that the stop ring 5 is sleeved on the drill bit 6, and the drill bit 6 is divided into a connecting part 61 and a drilling part 62 by the stop ring 5.

[0031] In some embodiments, the dial gauge 4 includes a measuring head 41 and a dial 42. The diameter of the second through hole 32 is larger than the diameter of the measuring head 41. At least a part of the measuring head 41 of the dial gauge 4 is accommodated in the second through hole 32. When the drill bit 6 is pressed down by the pressing mechanism 2, the drilling part 62 moves downward, the drilling part 62 abuts against the measuring head 41, and presses down the measuring head 41. The staff can read the pressing height from the dial 42. When the pressing height reaches the preset value, the pressing mechanism 2 is stopped, so as to ensure that the pressing height each time is the preset height value, which meets the height range of the drill bit 6 of the drilling machine.

[0032] In some embodiments, the pressing mechanism 2 includes a fixing seat 21, which is used to be detachably connected to the fixing plate 1. The fixing seat 21 is a vertically arranged arched structure, one end of which is a hinged end 212 hinged to the handle 23, and the other end is a limit end 211 for limiting the movement trajectory of the pressing rod 22. A guide hole is vertically arranged on the limit end 211, and the pressing rod 22 passes through the guide hole. During the pressing process, the pressing rod 22 moves downward along the guide hole to press down the drill bit 6 located in the first through hole 31.

[0033] In some embodiments, one end of the handle 23 is hinged to the hinge end 212, and the other end is used for pressing operation. A bending portion 231 is set in the middle of the handle 23 so that the handle 23 as a whole is not a straight line. The bending portion 231 is set close to the hinge end 212, so that the handle 23 is a labor-saving lever, which is convenient for pressing operation.

[0034] In some embodiments, the pressing mechanism 2 also includes a hinge 24, one end of the hinge 24 is hinged to the end of the connecting end 221 of the pressing rod 22, and the other end is hinged to the bending portion 231 of the handle 23. The handle 23 and the pressing member are connected by the hinge. When the handle 23 is pressed down, the pressing rod can be driven to press down the drill bit 6.

[0035] In some embodiments, an avoidance groove is provided on the hinge 24 to avoid the hinge end, so that the connection end 221, the hinge end 212, and the bending portion 231 connecting the pressing rod 22 and the hinge 24 are located on the same plane, which is convenient for the pressing operation.

[0036] In some embodiments, two hinges 24 are provided, which are symmetrically arranged at both ends of the hinge end 212 to make the pressing operation more stable.
