Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, but not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention. It should be noted that the embodiments and features of the embodiments in the present application may be arbitrarily combined with each other without conflict.
A hole digger with a waste material ejecting structure is disclosed, as shown in fig. 1, fig. 2 and fig. 3, comprising a positioning rod 1 with a drill bit at one end and a hole digger 2, wherein the hole digger 2 comprises a connecting plate 21 sleeved on the positioning rod 1, a cylinder 22 arranged on the connecting plate 21 and axially parallel to the positioning rod 1, and a tooth 221 arranged on the end of the cylinder 22 close to the drill bit. During the use, with the one end and the driving motor's of locating lever 1 non-be equipped with the drill bit output shaft for driving motor's output shaft drives locating lever 1 and trompil piece 2 and rotates, cuts out the hole with drill bit and tooth pressure 221.
Because the waste material is continuously generated and accumulated in the cylinder 22 in the process of cutting the hole, the waste material can influence the hole cutter to continuously and deeply open the hole when being accumulated to a certain degree. Therefore, when the operator needs to stop the machine and pour out the waste in the cylinder 22, the operator needs to continue working when the hole is opened to a certain extent, which has a great influence on the working efficiency.
Consequently, set up waste material pop-up structure in this application, be equipped with baffle 3 and plane spherical bearing 4 in the barrel 22 of this application, baffle 3 and plane spherical bearing 4 all offer the through-hole that the internal diameter is greater than 1 external diameter of locating lever to make baffle 3 and plane spherical bearing 4 all overlap and locate locating lever 1 but not rotate along with locating lever 1, also leave the gap between 3 tip of baffle and the barrel 22 inner wall simultaneously, avoid baffle 3 to be driven by trompil piece 2 and rotate. The plane spherical bearing 4 comprises a tightening ring 41, a loose ring 42 and balls 43 arranged between the tightening ring 41 and the loose ring 42, the loose ring 42 is connected with the baffle 3 through a spring 5, and the tightening ring 41 is connected with one surface of the connecting plate 21 close to the teeth 221. Of course, the inner diameter of the spring 5 is also larger than the outer diameter of the positioning rod 1, so that the spring 5 can not rotate along with the positioning rod 1.
The hole opening process is as follows:
1. after the machine is started, the positioning rod 1 and the hole-opening piece 2 rotate to drive the tightening ring 41 of the plane spherical bearing 4 to rotate, but under the action of the ball 43, the loose ring 42 of the plane spherical bearing 4 is connected with the spring 5 and the baffle 3 to keep still.
2. The drill bit of the positioning rod 1 drills out a positioning hole.
3. The teeth 221 of the punch 2 cut the plate.
4. The sheet waste abuts the baffle 3 and the spring 5 begins to contract.
5. After the plate is cut through, the baffle 3 pushes the waste out under the elastic force provided by the spring 5.
In order to make locating lever 1 can with driving motor's output shaft, locating lever 1 need set up longer, guarantee to have sufficient area of connection between locating lever 1 and the output shaft to improve connection stability, because locating lever 1 adopts the better material of quality to make usually, so this kind of mode can cause the higher problem of cost. Therefore, in the present embodiment, the present invention further includes a main body link 6, and the main body link 6 includes a driving portion 61 for connecting with a driving motor and a positioning rod connecting portion 62 for connecting with the positioning rod 1. The body link 6 may be made of a relatively poor material to reduce costs.
The main body connecting rod 6 can be fixedly connected with the positioning rod 1 or movably connected with the positioning rod. Since the positioning rod 1 is used to rotatably form the hole, the positioning rod 1 is worn after a long time use, and the positioning rod 1 needs to be replaced, so that the main body link 6 and the positioning rod 1 are movably connected to each other, that is, in the present embodiment, the positioning rod connecting portion 62 is provided with an axial through hole into which the positioning rod 1 can be inserted.
Under this condition, the hole digger is when using, and it is that the driving motor output shaft drives main part connecting rod 6 and rotates, main part connecting rod 6 drives locating lever 1 and rotates, so this moment, if take place smooth silk problem between locating lever connecting portion 62 and the locating lever 1, can influence trompil efficiency.
In order to improve the connection stability between the positioning rod connecting portion 62 and the positioning rod 1, the positioning rod connecting portion 62 is further provided with a radial through hole, the radial through hole is provided with an internal thread, and the fastening piece 7 is further provided with an external thread connected with the internal thread. After the positioning rod 1 is inserted into the axial through hole of the positioning rod coupling portion 62, the fastener 7 is inserted into the radial through hole, so that the end of the fastener 7 is tightly abutted against the surface of the positioning rod 1, and the slip is reduced by the friction force.
Furthermore, a fixing through hole with the same inner diameter as the radial through hole can be radially arranged on the positioning rod 1, and the fixing through hole is provided with an internal thread continuous with the internal thread of the radial through hole. Then, after the positioning rod 1 is inserted into the axial through hole of the positioning rod connecting part 62, the fastening piece 7 is in threaded connection with the radial through hole and the fixing through hole, so that the positioning rod connecting part 62 and the positioning rod 1 can be connected together in a radial connection mode, and the problem of thread slipping is completely avoided.
The positioning rod 1 and the hole-forming piece 2 can be fixedly connected, namely, the connecting plate 21 is fixedly sleeved on the positioning rod 1. But on the one hand, the integral structure is inconvenient to carry in consideration of the carrying problem. On the other hand, considering that the bit of the positioning rod 1 and the teeth 221 of the hole-forming member 2 may be worn to different degrees, the integral structure may cause one of the components to be worn more, and the entire hole-forming device may need to be replaced, which is costly. Therefore, in this embodiment, the positioning rod 1 is detachably connected to the hole forming member 2.
Since the positioning rod 1 needs to drive the hole forming member 2 to rotate, the connection stability between the positioning rod 1 and the hole forming member 2 is improved. The positioning rod connecting part 62 includes a fixing part 621 provided with a radial through hole and a connecting plate positioning part 622 having an outer diameter larger than that of the fixing part 621, and the fixing part 621 is close to the driving part 61 with respect to the connecting plate positioning part 622; a screw part 63 is arranged between the driving part 61 and the fixing part 621, and a nut 631 is sleeved on the screw part 63; the web 21 abuts on one surface of the web positioning portion 622 adjacent to the fixing portion 621, and abuts on the other surface of the end surface of the nut 631. Nut 631 is a hex nut. The clamp ring 41 is connected to the connecting plate positioning portion 622. In use, the coupling plate 21 is tightly pressed against the coupling plate positioning portion 622 by the nut 631 by rotation of the nut 631 on the threaded portion 63.
The above-described aspects may be implemented individually or in various combinations, and such variations are within the scope of the present invention.
