Abstract
A movable tightener comprises an L-shaped support. A rotary screw is arranged at one edge of the support, and a support cover matched with the support to form U shape is covered at the other edge of the support. The movable tightener is characterized in that the edge of the support matched with the support cover is provided with a groove, a slotted hole matched with the groove is arranged on the support cover, and a screw is arranged on the slotted hole. The movable tightener has the advantages of low cost, flexibility, convenience, high clamping efficiency and capability of protecting completeness of an objected to be clamped sufficiently.
Description
Technical field
The utility model relates to a kind of movable tightener.
Background technology
Anchor clamps commonly used are undamaged clampers in the present mechanical clamping processing occasion; as shown in Figure 1; clamp parts to be processed with two clampers; undamaged clamper comprise pressing plate 1 '; described pressing plate be provided with rotary screw 3 '; described rotary screw 3 ' the bottom by round pin be provided with protective sleeve 2 '; rotary screw 3 ' be used for clamping parts to be processed; though undamaged clamper can improve the efficient of parts clamping; and can prevent to destroy the globality and the object surfaces situation of object effectively; but the object height that is held (thickness) is subjected to certain restriction; when caught object exceeds the dimensions of undamaged clamper, just can not use the fixing undamaged clamper of of this sort dimensions.
Summary of the invention
The utility model will overcome existing undamaged clamper may face the problem that measurement category is restricted in clamping process, provide a kind of can be at any time according to the movable tightener of the actual size flexible modulation of object.
The technical solution of the utility model is:
Movable tightener, comprise L bracket, one side of described support is provided with rotary screw, the another side of described support is with and is mated the support casing that constitutes U-shaped, it is characterized in that: one side the groove that has that described support is cooperating with described support casing, described support casing is provided with the slotted eye with described groove fit, and described slotted eye is provided with screw.
Further, described screw is fixed on described support in the described support casing by pad and nut.
Further, the screw rod of described rotary screw bottom has cannelure, and the outside of described cannelure is provided with protective sleeve, and described protective sleeve passes through the round pin fixed cover on the screw rod of described rotary screw.
During use, cooperate as movable tightener use with two movable U-shaped supports, when the object that is held more, when thickness has exceeded original support specification, as long as nut and pad that releases clamp puts, support is shifted out and is adjusted to corresponding dimension of object in support casing, and with nut and pad lock-screw again, like this, movable tightener just can be at any time according to the specification size of the actual size flexible modulation U-shaped support of object, to meet the U-shaped support of corresponding dimension of object specification size.
Simultaneously; have cannelure in the screw rod of rotary screw; by round pin the screw rod of protective sleeve and rotary screw is linked together; when rotary screw when rotated; protective sleeve and round pin are motionless; and screw rod can rotate in round pin and cannelure; like this, in the clamping course of work, protective sleeve can only be along with the screw axial motion; and can not rotate; so just avoided the direct friction with contact-making surface, also just protected contact-making surface, and the contact area of protective sleeve head is bigger than the screw rod area of rotation screw; reduce the pressure of contact-making surface, can in contact-making surface, not produce the phenomenon in hole.Therefore the clamping efficient of its equipment is better, flexible.
The beneficial effects of the utility model: with low cost, flexible, clamping efficient height, and the integrality of the gripping object that adequately protected.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing:
With reference to Fig. 2-Figure 10, movable tightener described in the utility model, comprise L bracket 1, one side of described support 1 is provided with rotary screw 11, the another side of described support 1 is with and is mated the support casing 2 that constitutes U-shaped, described support 1 has groove 3 on the one side that cooperates with described support casing, and described support casing 2 is provided with the slotted eye 4 that cooperates with described groove 3, and described slotted eye 4 is provided with screw 21.
Described screw 21 is fixed on described support 1 in the described support casing 2 by pad 22 and nut 23.
The screw rod bottom of described rotary screw 11 has cannelure, and the outside of described cannelure is provided with protective sleeve 12, and described protective sleeve 12 passes through round pin 13 fixed covers on the screw rod of described rotary screw 11.
During use, cooperate as movable tightener use with two movable U-shaped supports, when the object that is held more, when thickness has exceeded original support specification, as long as nut 23 and pad 22 on the releases clamp cover 2, support 1 is shifted out and is adjusted to corresponding dimension of object in support casing 2, and with nut 23 and pad 22 lock-screw 21 again, like this, movable tightener just can be at any time according to the specification size of the actual size flexible modulation U-shaped support of object, to meet the U-shaped support of corresponding dimension of object specification size.
Simultaneously; have cannelure in the screw rod of rotary screw 11; by round pin 13 screw rod of protective sleeve 12 and rotary screw 11 is linked together; when rotary screw 11 when rotated; protective sleeve 12 and round pin 13 are motionless; and screw rod can rotate in round pin 13 and cannelure; like this, in the clamping course of work, protective sleeve 12 can only be along with the screw axial motion; and can not rotate; so just avoided the direct friction with contact-making surface, also just protected contact-making surface, and the contact area of protective sleeve 12 heads is bigger than the screw rod area of rotation screw 11; reduce the pressure of contact-making surface, can in contact-making surface, not produce the phenomenon in hole.Therefore the clamping efficient of its equipment is better, flexible.
The described content of this specification embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to the utility model design the equivalent technologies means that can expect.
