Abstract
An open-end resilient key assembling tool is characterized in that a central shaft and a handle are connected to form an integrated body, three clamping arms with triangular cross-sections are circumferentially and evenly distributed and fixed on the handle, a conical nut is engaged with the clamping arms with cone threads, a three-jaw clamping head is mounted on a free end of the clamping arm through a pin shaft, a spring ring is mounted in the inner side of the clamping arm for supporting, one end of a support shaft is mounted at the free end of the central shaft, the other end can be inserted into an internal hole of an open-end resilient key, an external circle of the support shaft has a taper, and the diameter of a small end is less than that of the internal hole of the open-end resilient key. When the conical nut rotates toward the free end of a support arm, three support arms bear force to contract toward the center, thereby driving the clamping head to clamp the open-end resilient key. Compared with the prior art, the open-end resilient key assembling tool has the advantages of convenient and quick assembling of the open-end resilient key, enhancing the working efficiency, reducing the labor intensity and ensuring the assembling quality of the open-end resilient key.
Description
Technical field
The utility model relates to a kind of opening resilient key dismantling device.
Background technology
The opening resilient key is widely used because of its accurate positioning, difficult drop-off, low cost and other advantages, often wants the fitting opening resilient key as uses such as location, splines in a lot of engineering goods.Be it directly to be knocked in mostly in the installation of product with hammer, this method promptly makes the distortion of opening resilient key dangerous again easily, and this method is an assemble method, for the not good method of the nondestructive demounting of opening resilient key, for the ease of the installation of opening resilient key, and realize nondestructive demounting.
Summary of the invention
The purpose of this utility model is to overcome weak point in the prior art and has designed a kind of opening resilient key dismantling device, its structure is: central shaft and handle are connected as a single entity, and three cross sections clamping limb triangular in shape is uniform in a circumferential direction and be fixed on the handle; The circular cone nut matches with the clamping limb that has the cone screw thread; Three-jaw chuck is installed in the free end of clamping limb by bearing pin; Installed inside at clamping limb has its passive turn; One end of back shaft can be installed in the free end of central shaft, and the other end can insert in the endoporus of opening resilient key.The back shaft cylindrical has tapering, and end diameter is less than opening resilient key diameter of bore.
During assembling the opening resilient key is put between chuck and the back shaft, by the rotating cone nut clamping limb is shunk, the opening resilient key is clamped, and the opening resilient key is packed in the pin-and-hole thereby drive chuck, finish and back rotating cone nut is installed is unclamped chuck and get final product, method of operating is identical during dismounting.Back shaft is positioned at opening elasticity pin-and-hole center, and the opening resilient key is played a supportive role, and prevents the distortion of compression process split shed resilient key, so will change different back shafts according to the difference of opening resilient key internal diameter.The effect of spring is to make clamping limb return to the origin-location after the circular cone nut unclamps.
Installed inside at clamping limb has turn, and clamping limb is played a supportive role, and makes clamping limb open up into maximum position; Back shaft is installed in the free end of central shaft, and the opening resilient key is played the support positioning action, prevents to be out of shape when the opening resilient key is stressed.
The circular cone nut has the circular cone internal thread, match with circular cone external screw thread on the support arm, when the circular cone nut when the support arm free end rotates, three support arms are stressed to be shunk to the center, thereby drive chuck the opening resilient key is clamped.Three-jaw chuck is connected in the free end of support arm respectively by bearing pin, three-jaw chuck can be the rotation that certain angle is made at the center with the bearing pin, the whole clamping face that has guaranteed chuck when clamping the opening resilient key all contacts with the opening resilient key, make the opening resilient key stressed evenly, avoid the situation of line contact to take place.
Back shaft is installed on the free end of central shaft, changes corresponding back shaft according to the difference of opening resilient key internal diameter size, makes this instrument be applicable to the opening resilient key of different model.The back shaft cylindrical has certain taper, and end diameter is convenient to the installation and removal of opening resilient key like this less than opening resilient key diameter of bore.
Compared with prior art the utlity model has following advantage, convenient to disassembly to the opening resilient key increased work efficiency, and reduces labor intensity, and guarantees the dismounting quality of opening resilient key.
Description of drawings
Fig. 1 is the utility model opening resilient key dismantling device structural representation.
The specific embodiment
Now 1 the utility model is further explained in conjunction with the accompanying drawings, and the structure of this opening resilient key dismantling device is: central shaft 6 is connected as a single entity with handle 9, and three cross sections clamping limb 7 triangular in shape is uniform in a circumferential direction and be fixed on the handle 9; Circular cone nut 8 matches with the clamping limb 7 that has the cone screw thread; Three-jaw chuck 2 is installed in the free end of clamping limb 7 by bearing pin 3; Installed inside at clamping limb 7 has its passive turn 5; One end of back shaft 4 can be installed in the free end of central shaft 6, and the other end can insert in the endoporus of opening resilient key 1.
Claims (2)
