Abstract
The utility model discloses a clamp, relating to the technical field of multipurpose instrument manufacture. The clamp comprises an arched clamp body and a threaded rod arranged on the clamp body in a penetrated mode through a screw thread, and is characterized in that a screw thread where the threaded rod is connected with the clamp body is a trapezoidal thread; a through hole where a force applying rod penetrates through is arranged in one end of the threaded rod, which is arranged on the external part of the arched clamp body, and the hardness of a cylinder on one end of the threaded rod, which is arranged on the inner side of the clamp body, is HRC (Rockwell hardness) 50-55. Compared with the prior art, the clamp has the advantages that the through hole where the force applying rod penetrates through is arranged on the head part of the clamp, and an exciter can be conveniently rigidly fastened on an excited part by only using one force applying rod without using a wrench.
Description
Technical field
The utility model relates to general utility tool manufacturing technology field, and especially a kind of being used for is fastened on the instrument on another object with an object.
Background technology
This instrument is used for vibrator and other part clamping in oscillating aging technology; Be the two to be clamped on the caliper part is carried out the subresonance vibration; Eliminate the specific purpose tool of residual stress, so anchor clamps are also bearing the effect of resonance power greatly in the process of parts processed.The technical scheme of existing a kind of anchor clamps is: an arc caliper is arranged; Be coated with the screw rod of regular screw threads at an end of caliper; This screw rod has one section to be that cross section is foursquare square toes in the termination of the caliper outside one end, and this screw rod is positioned at the inboard end of caliper has one section to be cylinder.
In use there is following deficiency in the technical scheme of this anchor clamps: must pull the square toes of screw rod when 1, being fastened on vibrator on the part rigidly with spanner repeatedly, and very inconvenient; 2, the screw rod of regular screw threads is in the oscillating aging process, and coupling mechanism force is not enough, and loosening easily, vibrator sometimes also can fall down from part, causes vibrator to damage; 3, the cylindrical compressing end of screw rod is fragile inadequately because of hardness, and also have only 250 hours the service life of anchor clamps.
Summary of the invention
The utility model technical problem to be solved provides more reliable, the easy to operate anchor clamps of a kind of clamping part.
The technical scheme that technical solution problem of the present invention is adopted is: a kind of anchor clamps, and include arc caliper and be installed on the screw rod on this caliper through screw thread, the screw thread that said screw rod is connected with said caliper is a trapezoidal thread; Said screw rod is positioned at the outside end of arc caliper and is provided with the through hole that installs boosting-rod.
In the above-mentioned clamp technology scheme, technical scheme can also be more specifically: the cylindrical hardness that said screw rod is positioned at the inboard end of caliper is HRC50-55.
Owing to adopted technique scheme; The utility model compared with prior art, the beneficial effect that has is: 1, the head of screw rod has the through hole that installs boosting-rod, without spanner; Need only a boosting-rod, just can be fastened on vibrator on the part rigidly easily; 2, the screw thread that is connected with caliper of screw rod is a trapezoidal thread, and coupling mechanism force is strong, and holding capacity is big, and vibrator can not become flexible in the resonance ag(e)ing process; 3, the hardness of the cylindrical compressing end of screw rod is high, and is also not fragile, and bring up to 5000 hour by 250 hours of prior art service life.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further to detail:
Anchor clamps as shown in Figure 1 have arc caliper 2 and are installed on the screw rod 1 on the caliper 2 through screw thread, and screw rod 1 is trapezoidal thread Tr32 * 6 with the connecting thread of caliper 2; Screw rod 1 is that head is that one section diameter is 50 millimeters of φ, and length is 50 millimeters cylinder, and there is the through hole of 24 millimeters of φ at this cylindrical middle part; The stage casing of screw rod 1 is the trapezoidal thread of one section Tr32 * 6, and length is 165 millimeters; Afterbody is that one section diameter is 18 millimeters of φ, and length is 20 millimeters cylinder, and this cylindrical hardness is HRC50-55.
The thickness of caliper 2 is 50 millimeters, and the cross section of caliper 2 is a square, and the arcuate openings height of caliper 2 is 165 millimeters, and the arcuate openings degree of depth of caliper 2 is 95 millimeters.
Anchor clamps as shown in Figure 1 use a boosting-rod, pass the through hole of screw rod 1 head, tighten screw rod 1 with regard to rotatable, thereby are fastened on vibrator rigidly on the part that shaken easily.
Claims (2)
1. anchor clamps include arc caliper (2) and are installed on the screw rod (1) on this caliper (2) through screw thread, and it is characterized in that: the screw thread that said screw rod (1) is connected with said caliper (2) is a trapezoidal thread; Said screw rod (1) is positioned at the outside end of arc caliper (2) and is provided with the through hole that installs boosting-rod.
