Abstract
The utility model discloses an inner cavity positioning and clamping mechanism. The inner cavity positioning and clamping mechanism comprises a mold plate, an support plate, a clamping plate, pressing plates, an adjustment screw, shaft pins and a support frame, wherein the support plate and the clamping plate are respectively installed at one side of the mold plate, the support frame is installed at the other side of the mold plate, the movable pressing plates are symmetrically installed at two sides of the support frame, a pressing plate inner cavity is formed in each pressing plate, each shaft pin is arranged in each pressing plate inner cavity, and the adjustment screw is connected with the pressing plates through the shaft pins in the pressing plate inner cavities. According to the inner cavity positioning and clamping mechanism, the pressing plates are used for positioning the inner wall of a workpiece which is thin in wall and easy to deform, and enables the machined workpiece to have the advantages of being even in wall thicknesses at two sides, good in symmetrical degree, and high in accuracy.
Description
Technical field
The utility model relates to a kind of clamp mechanism, particularly a kind of building-block machine inner chamber positioning and clamping mechanism.
Background technology
Building-block machine is as the basis take seriation and standardized universal component, be equipped with a small amount of special-purpose member carries out machining by predetermined operation to one or more workpiece lathe, can be simultaneously on the building-block machine on several direction adopt the much knives tool that one or plurality of workpieces are processed, can reduce like this carrying and the floor space of material, the realization operation is concentrated, has been improved production efficiency and reduces cost.
In the Modern Modular Machine Tool processing, part to be processed exists of all kinds, in addition, also has many irregular parts, such as bent axle, connecting rod, semiaxis, axle tube, back axle etc.; Its positioning datum that adopts separately is also of all kinds, the employing v block that has, have with the cylindrical self-centering, when the part part to be processed is the yielding workpiece of thin-walled, rear both sides wall thickness is even, symmetry good, required precision is higher because this workpiece requires to machine, and general outside clamping mode can not satisfy these requirements, therefore needs a kind of novel positioning and clamping mechanism of exploitation.
The utility model content
It is a kind of in building-block machine processing that the purpose of this utility model is to provide, to the inner chamber positioning and clamping mechanism of thin-walled, yielding workpiece location.
In order to solve the problem of above-mentioned proposition, the utility model provides following technical scheme:
A kind of inner chamber positioning and clamping mechanism, comprise template, gripper shoe, cramping plate, pressing plate, adjustment screw, pivot pin and support, described gripper shoe, cramping plate are installed on respectively the template one side, described support is installed on the template another side, be positioned on the template of described support two sides symmetry movably pressing plate is installed, also be provided with the pressing plate inner chamber in the described pressing plate, described bearing pin is installed in the pressing plate inner chamber, and the bearing pin of described adjustment screw in the pressing plate inner chamber is connected with pressing plate.
Above-mentioned inner chamber positioning and clamping mechanism, wherein: mounting screw is gone back in described gripper shoe inboard.
Above-mentioned inner chamber positioning and clamping mechanism, wherein: the end between described bearing pin and pressing plate inner chamber also is provided with pad.
Above-mentioned inner chamber positioning and clamping mechanism, wherein: the quantity of described pressing plate is 4, respectively symmetrical being installed on the template of support two sides.
The utlity model has following beneficial effect:
Use pressing plate that the inwall of thin-walled, yielding workpiece is positioned, so that workpiece has the advantage that the both sides wall thickness is even, symmetry good, precision is high after processing.

The specific embodiment
The utility model is described in more detail below in conjunction with the drawings and specific embodiments.
Specific embodiment, as Figure 1-3, the utility model provides a kind of inner chamber positioning and clamping mechanism, comprise template 1, gripper shoe 2, cramping plate 4, pressing plate 5, adjust screw 7, pivot pin 8 and support 9, described gripper shoe 2, cramping plate 4 are installed on respectively template 1 one side, described support 9 is installed on template 1 another side, be positioned on the template 1 of described support 9 two sides symmetry movably pressing plate 5 is installed, also be provided with pressing plate inner chamber 10 in the described pressing plate 5, described bearing pin 8 is installed in the pressing plate inner chamber 10, and the bearing pin 8 of described adjustment screw 7 in pressing plate inner chamber 10 is connected with pressing plate 5.
In the utility model: mounting screw 3 is gone back in described gripper shoe 2 inboards, and it is soket head cap screw; And the end between described bearing pin 8 and pressing plate inner chamber 10 also is provided with pad 6; The quantity of described pressing plate 5 is 4, respectively symmetrical being installed on the template 1 of support 9 two sides.
The below is further described the course of work of the present utility model:
Support 9 is fixed on the template 1, fix after soket head cap screw 3 finds the position with part to be processed by adjusting, above the inner chamber with pressing plate 5 alignment pieces, adjust simultaneously screw 7, make pivot pin 8 left rotation and right rotation that are arranged in pressing plate inner chamber 10, make pressing plate 5 realize left and right relatively simultaneously motion, thus top tight workpiece inner chamber location; And the setting of cramping plate 4 make template 1 relative with part to be processed fixing, can carry out processing parts; Use this method and structure that the inwall of thin-walled, yielding workpiece is positioned, so that workpiece has the advantage that the both sides wall thickness is even, symmetry good, precision is high after processing.
Above-described embodiment is the better embodiment of the utility model; but embodiment of the present utility model is not restricted to the described embodiments; and other any do not deviate from change, the modification done under Spirit Essence of the present utility model and the principle, substitutes, combination, simplify; all should be the substitute mode of equivalence, be included within the protection domain of the present utility model.
