Abstract
The utility model discloses a worm gear and worm type permanent magnetic clamp, which comprises a clamp main frame, wherein a fixing arm and a mobile arm are arranged on the clamp main frame, and the worm gear and worm mechanism transmission is utilized for the mobile arm. Permanent magnets are arranged on the working surfaces of the fixing arm and the mobile arm. The clamp has the advantages of simple structure, reasonable design, and precision and labor saving in clamp assembly, and is provided with a self-lock function, relative displacement between a clamped workpiece and the clamp does not easy occur, the clamp can be widely popularized in mechanical industry, and has wide application prospect.
Description
Technical field
The utility model relates to a kind of anchor clamps, particularly relates to a kind of Worm-gear type permanent magnetism anchor clamps.
Background technology
At present, in the assembling of machined steel structure, employed anchor clamps all are common stainless steel anchor clamps, and the transfer arm of anchor clamps is loosening easily during use, and use quite effort.
The utility model content
The purpose of this utility model just provides a kind of auto-lock function that has, and clamping labour-saving Worm-gear type permanent magnetism anchor clamps, can solve the problems of the technologies described above fully.
The purpose of this utility model realizes by following technical proposals:
A kind of Worm-gear type permanent magnetism anchor clamps comprise the anchor clamps body frame, and fixed arm and transfer arm are arranged on the anchor clamps body frame, and described transfer arm adopts the worm-and-wheel gear transmission.
Further, described fixed arm and transfer arm working face are provided with permanent magnet.
Adopt this structure can guarantee that anchor clamps in use closely link to each other with caught workpiece, do not produce relative displacement.
Compared with prior art, the beneficial effects of the utility model are:
Simple in structure, reasonable in design, clamping is accurately laborsaving, has auto-lock function, and caught workpiece and anchor clamps are difficult for producing relative displacement, can extensively promote at machinery industry, are with a wide range of applications.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiments and the drawings the utility model is further described.
As shown in Figure 1, a kind of Worm-gear type permanent magnetism anchor clamps, comprise anchor clamps body frame 8, fixed arm 4 and transfer arm 5 are arranged on the anchor clamps body frame 8, described transfer arm 5 adopts the worm-and-wheel gear transmission, transfer arm 5 one ends are connected with worm gear 1, and worm gear 1 and worm screw 2 match mobile at tooth bar 3 under the driving that is incorporated in worm screw 2, and the end of worm screw 2 stretches out anchor clamps body frame 8 sides and is provided with rotation hand wheel 6.The working face of described fixed arm 4 and transfer arm 5 is provided with permanent magnet 7.
During use, rotate rotation hand wheel 6 and drive worm screw 2 rotations, worm gear 1 drives transfer arm 5 along tooth bar 3 move left and right, realizes the clamping of workpiece.And fixed arm 4 can be to the clamping face absorption of workpiece with the permanent magnet 7 on transfer arm 5 working faces, and the assurance anchor clamps in use closely link to each other with caught workpiece, do not produce relative displacement.
The above only is preferred embodiment of the present utility model; not in order to limit the utility model; all any modifications of within spirit of the present utility model and principle, doing, be equal to and replace and improvement etc., all should be included within the protection domain of the present utility model.
