Description

Technical Field

[0001] The utility model relates to a cutter, in particular to a cutter for cleaning overflowed rubber rings in a torch housing component. Background Art

[0002] like Figure 1 to Figure 4 As shown, an existing torch shell assembly includes an upper shell 1a, a lower shell 2a and a connecting sleeve 3a for connecting the upper shell 1a and the lower shell 2a. The upper shell 1a and the lower shell 2a are both hollow structures, and components such as gas cylinders, burners and air flow distributors can be arranged inside. The upper shell 1a is made of aluminum alloy, and the lower shell 2a is made of plastic. The two are bonded together by the connecting sleeve 3a. After bonding, glue 4a will overflow from the bonding place of the connecting sleeve 3a to form an overflow rubber ring 5a. The lower shell 2a is mainly used for holding the handle.

[0003] Since the torch itself has a weight requirement and must not be greater than the specified weight, and the overflow rubber ring is located just where the gas cylinder is placed, the existence of the overflow rubber ring affects the setting of the gas cylinder, so the overflow rubber ring needs to be scraped off. At present, the common treatment method is to clean it with saw blades and files, which has the following shortcomings: the overflow rubber ring is located in the middle of the torch shell assembly, and the hole depth cannot exert effective force, resulting in unclean cleaning and low efficiency. If you are not careful, it may even damage the torch shell assembly, causing irreparable problems. Utility Model Content

[0004] The technical problem to be solved by the utility model is to provide a rubber cutting tool for the overflow rubber ring of a torch housing component with accurate cutting and high cutting efficiency in view of the above technical status quo.

[0005] The utility model solves the above technical problems by adopting the following technical solution: a rubber tapping tool for the rubber ring of the torch housing assembly, characterized in that it includes

[0006] A guide sleeve having a hollow inner cavity formed in the axial direction;

[0007] A supply push rod is disposed in the hollow inner cavity of the guide cylinder and has an inclined surface formed at the front end;

[0008] A first spring is sleeved on the front end of the aforementioned feeding ejector rod and is located in the hollow inner cavity of the guide cylinder, and the first spring forces the feeding ejector rod to always keep a tendency to approach the hand wheel;

[0009] A hand wheel is axially movable on the port of the hollow inner cavity of the guide cylinder, and the inner end of the hand wheel has an ejection portion that can squeeze the supply ejector rod to move forward;

[0010] A tool holder is arranged at the front end of the guide tube and can move transversely perpendicular to the axial direction of the guide tube. The tool holder has an inclined block portion that cooperates with the inclined portion, and the inclined block portion extends into the hollow inner cavity of the guide tube;

[0011] A blade, disposed on the outer end surface of the aforementioned tool holder;

[0012] A spring seat, one end of which is connected to the front end of the guide cylinder, and the other end of which is provided with an abutment portion extending along the length direction of the guide cylinder, wherein a mounting gap is provided between the abutment portion and the tool holder;

[0013] The second spring is arranged in the installation gap between the aforementioned abutting portion and the tool holder.

[0014] The ejection portion of the hand wheel has an external thread, and correspondingly, the hollow inner cavity of the guide cylinder has an internal thread adapted to the external thread, so that the downward movement depth of the ejector rod can be accurately controlled.

[0015] Considering the convenience of operation, the outer wall of the guide cylinder has a handle for driving the guide cylinder to rotate.

[0016] To achieve maximum cutting completeness, the cutting edge of the blade is inclined to correspond to the inner wall of the torch housing assembly.

[0017] Considering the installation of the second spring, the abutting portion has a first groove, the front end face of the tool holder has a second groove, the inclined block portion is located at the rear end face of the tool holder, and the two ends of the second spring are respectively placed in the aforementioned first groove and second groove.

[0018] The knife clamp has two second grooves arranged longitudinally, the blade is arranged between the second grooves, the spring seats are two and are respectively located on both sides of the knife clamp, and correspondingly, the second springs are two and are respectively arranged corresponding to the second groove and the first groove. The knife clamp is acted upon by the two second springs, so that the lateral movement becomes stable and reliable. At the same time, the spring seat is arranged in the opposite direction relative to the knife clamp (the abutting part is located outside the knife clamp), which can well protect the exposed blade and avoid the occurrence of blade injury during operation.

[0019] Furthermore, the tool holders are two and are respectively arranged on both sides of the front end of the guide tube, and each tool holder is equipped with its own blade, spring seat and second spring.

[0020] The outer wall of the guide tube is provided with a support sleeve adapted to the inner wall of the torch housing assembly. Further, the support sleeves are two and are respectively located at the upper and lower ends of the guide tube. The support sleeve plays the role of axial positioning.

[0042] The supply ejector rod 3 is arranged in the hollow inner cavity of the guide cylinder 1 and has a bevel portion formed at the front end; the supply ejector rod 3 includes a main body 31 and an extension portion 32 extending forward from the front end of the main body 31, the front end of the extension portion 32 is a cone 33, and the bevel portion is the outer surface of the cone 33.

[0043] The first spring 34 is sleeved on the extension portion 32 and one end thereof abuts against the step portion 14 of the inner wall of the cylinder. The first spring 34 is located in the hollow inner cavity of the guide cylinder 1 , and the first spring 34 forces the supply ejector rod 3 to always keep a tendency to approach the hand wheel 2 .

[0044] The hand wheel 2 is axially movable on the port of the hollow inner cavity of the guide cylinder 1 , and the inner end of the hand wheel 2 has an ejection portion 21 that can squeeze and supply the ejector rod 3 to move forward; the ejection portion 21 has an external thread that matches the internal thread of the guide cylinder 1 .

[0045] The blade clamping mechanism consists of two groups which are respectively arranged at two sides of the front end of the guide tube 1 , and each group of the blade clamping mechanism comprises a blade clamp 5 , a blade 6 and a spring seat 7 .

[0046] The tool clamp 5 is arranged at the front end of the guide tube 1 and can move laterally perpendicular to the axial direction of the guide tube 1. The tool clamp 5 has an inclined block portion 51 that cooperates with the inclined portion, and the inclined block portion 51 extends into the hollow inner cavity of the guide tube 1; the blade 6 is arranged on the outer end surface of the tool clamp 5; the blade 6 has an inclined edge to correspond to the inner wall of the torch shell assembly.

[0047] One end of the spring seat 7 is connected to the front end of the guide cylinder 1 by a screw 72, and the other end has an abutment portion 74 extending along the length direction of the guide cylinder 1, and there is an installation gap between the abutment portion 74 and the tool clamp 5; the second spring 73 is arranged in the installation gap between the abutment portion 74 and the tool clamp 5.

[0048] Combination Figure 8 and Fig. 9As shown, the abutting portion 74 in this embodiment has a first groove 71, the front end surface of the tool holder 5 has a second groove 52, the inclined block portion 51 is located at the rear end surface of the tool holder 5, and the two ends of the second spring 73 are respectively placed in the first groove 71 and the second groove 52.
