Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention will be described in detail with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention.

In the description of the present invention, it is to be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate orientations or positional relationships based on those shown in the drawings, and are only for convenience of description and simplicity of description, but do not indicate or imply that the device or element being referred to must have a particular orientation, be constructed and operated in a particular orientation, and thus, should not be considered as limiting the present invention.

As shown in fig. 1 and 2, a machine shell shaft hole machining and detecting clamp comprises a base 10, wherein a positioning pin 1 used for being inserted into a positioning hole at the bottom of a machine shell 8 and a limiting stop pin 5 used for abutting against the left end of the machine shell 8 are arranged on the base 10, and the machine shell 8 can be positioned through the combined action of the positioning pin 1 and the limiting stop pin 5. Because the positioning pin 1 is vertically inserted into the positioning hole at the bottom of the casing 8, only the positioning function is achieved, and the positioning hole at the bottom of the casing 8 is relatively suspended, a supporting step for supporting the casing 8 is further arranged on the side portion of the positioning pin 1, and the phenomenon that the suspended portion of the casing 8 sinks is avoided. Be equipped with three brace table nail 7 that are used for supporting casing 8 on the base 10, one side of every brace table nail 7 all is equipped with a holder, brace table nail 7 and holder mutually support to centre gripping casing 8. The clamping piece comprises a pressing plate 3, a spring 13, a positioning screw rod 6 and a supporting screw rod 4, the bottom end of the supporting screw rod 4 is abutted against the base 10, the top end of the supporting screw rod is connected with the tail end of the pressing plate 3, the pressing plate 3 can be supported, and the pressing plate 3 is matched to compress the machine shell 8. The bottom end of the positioning screw rod 6 is connected to the base 10, and the top end of the positioning screw rod upwards penetrates through the middle of the pressing plate 3, so that the pressing plate 3 can rotate around the positioning screw rod 6. The top end and the lower part of the positioning screw rod 6 are respectively connected with a locking nut 2 used for pressing the pressing plate 3 and fixing the positioning screw rod 6, and the front end of the pressing plate 3 can press the machine shell 8 downwards on the corresponding supporting table nail 7 by rotating each locking nut 2. Spring 13 suit is on positioning screw 6 and its upper and lower both ends lean on respectively in clamp plate 3 and the lock nut 2 of connecting positioning screw 6 lower part, and after lock nut 2 is not hard up, clamp plate 3 is supported by support screw 4, can avoid appearing the phenomenon that clamp plate 3 askew falls to casing 8 at the dismantlement in-process. The locking nut 2 comprises a first nut 2c and a second nut 2b which are abutted to each other from top to bottom and fixedly connected together, two sides of the second nut 2b are respectively connected with a first driving lever 2a, and the locking nut 2 is of an integrally formed structure. As another alternative structure, the first nut 2c, the second nut 2b and the first shift lever 2a of the lock nut 2 are connected to each other by welding. In the dismounting process of the clamp, because the first driving lever 2a can provide longer torque, the first driving lever 2a can be directly rotated by hands to lock or unscrew the locking nut 2, so that the dismounting of the positioning screw rod 6 and the pressing plate 3 is completed, the use of external tools such as a spanner is reduced, and the dismounting of the clamp is more convenient. When the clamp is used for processing, the first driving lever 2a can be turned by hand to lock the locking nut 2, and then the first nut 2c can be turned by a tool such as a wrench to continuously tighten the locking nut 2 because the locking degree is higher. Since the locking nut 2 is locked by rotating the first shift lever 2a, the locking nut 2 can be screwed to the locking degree required by processing without screwing too much when the first nut 2c is rotated by a tool such as a wrench. In the dismantlement in-process of this anchor clamps, behind lock nut 2 on the unscrewed clamp plate 3, clamp plate 3 can be supported by spring 13, avoid clamp plate 3 directly askew to fall on casing 8, stir clamp plate 3 a little and make its certain angle of deflection after, operating personnel can take off casing 8 fast, owing to do not have the hand of vacating to hold clamp plate 3 also can make clamp plate 3 keep the height of self under spring 13's effect this moment, so when installing casing 8 once more, directly on 3 rotatory casings 8 with clamp plate, just can lock clamp plate 3 very easily, compress tightly casing 8, the convenience of anchor clamps dismouting has further been improved.

In addition, a movable stop pin 9 for abutting against the right side end of the machine shell 8 is further arranged on the base 10, and the movable stop pin 9 is connected to the base 10 through a locking bolt 12. The movable leaning pin can be matched with the limit stop pin 5 leaning against the left end of the machine shell 8 by leaning against the right end of the machine shell 8, and the machine shell 8 is fixed. This locking bolt 12 includes the head and has the pole portion of external screw thread, and the both sides of head bottom are equipped with a second driving lever respectively, and at the dismouting in-process, only need to rotate the second driving lever can lock movable backing pin 9, and when this anchor clamps were used for the processing usage, then tools such as reusable spanner twist locking bolt 12 head upper ends and continue to lock, so not only can reduce the use of outside instrument to a great extent, also can improve the convenience that anchor clamps dismantled. The bottom of the base 10 is fixedly connected with a lathe connecting disc 11 so that the clamp can be easily installed on a lathe.

In conclusion, the clamp is simple in structure, the locking nut 2 can be directly and manually rotated to lock and loosen the pressing plate 3 by arranging the locking nut 2, so that the use of external tools can be reduced to a great extent, and the clamp can be more conveniently disassembled and assembled by stirring the first stirring rod 2a to rotate the locking nut 2; through set up spring 13 on positioning screw 6, can make clamp plate 3 also can be supported by spring 13 after not hard up, avoid clamp plate 3 directly askew to fall on casing 8, stir clamp plate 3 a little and make its certain angle back that deflects, operating personnel can take off casing 8 fast, owing to need not to vacate the hand and hold clamp plate 3 also can make clamp plate 3 keep the height of self under spring 13's effect this moment, so when installing casing 8 once more, directly with clamp plate 3 rotatory to casing 8 on, just can lock clamp plate 3 very easily, compress tightly casing 8, the convenience of anchor clamps dismouting has further been improved.

Although the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes may be made and equivalents may be substituted without departing from the scope of the invention.
