Abstract
The utility model relates to the field of workpiece clamping devices for machine tools, in particular to a clamp for eliminating clamping deformation in a hole machining procedure, which comprises a positioning plate (1), a left supporting leg (21) and a right supporting leg (22). The left supporting leg (21) and the right supporting leg (22) are respectively fixed on a left side and a right side below the positioning plate (1). The clamp is characterized by further comprising process blocks, a floating supporting block (41) and a spring (42); the number of the process blocks is four; the process blocks are respectively a process block I (31), a process block II (32), a process block III (33) and a process block IV (34); the process blocks are all perpendicularly fixed above the positioning plate (1); and the floating supporting block (41) is fixed at the top of the process block III (33) through the spring. The clamp has a simple structure, convenience in use, flexibility in regulation and high in machining precision.
Description
Technical field
The utility model relates to the Workpiece clamping device field that is used for lathe, is specially a kind of anchor clamps of clamping deformation when being used to eliminate hole processing.
Background technology
Often having various structures and shape in the automobile production all needs processing with complicated parts, and shown in Figure 1 is a kind of part to be processed, part 10 complex contour not only as can be seen, and need machined surface more, face processing, hole processing etc. are arranged.For guaranteeing precision, add and to implement clamping to part man-hour.Present clamping to this class part, anchor clamps such as many employing chucks, because the complex structure of part 10, there is more stressed weak spot, under the acting in conjunction of cutter, deformation taking place easily, thereby influences final machining accuracy when anchor clamps chucking power and machining, especially for the precision in hole, more difficult assurance.
The utility model content
In order to overcome the defective of prior art, provide a kind of, the utility model discloses a kind of anchor clamps of clamping deformation when being used to eliminate hole processing.
The utility model reaches goal of the invention by following technical solution:
A kind of anchor clamps of clamping deformation when being used to eliminate hole processing, comprise location-plate, left feet and right feet, left side feet and right feet are separately fixed at the left and right sides of location-plate below, it is characterized in that: also comprise technology piece, unsteady back-up block and spring, the quantity of technology piece is 4, be respectively technology piece one, technology piece two, technology piece three and technology piece four, the technology piece all is vertically fixed on the top of location-plate, and the back-up block that floats is fixed on the top of technology piece three by spring.
The described anchor clamps of clamping deformation when being used to eliminate hole processing, it is characterized in that: the Ra value of the upper surface surface roughness of the upper surface of location-plate and technology piece is all 0.4～0.8, and the technology piece all is vertically fixed on the top of location-plate by bolted mode.
When the utility model uses, part to be processed is leaned on last location-plate, technology piece and unsteady back-up block, and clamped, because the effect of unsteady back-up block is arranged, when chucking power is excessive when making that part to be processed might deformation take place, by the adjusting of spring, can the release portion chucking power, thereby avoid the deformation of part to be processed, guaranteed machining accuracy.The beneficial effects of the utility model are: simple in structure, easy to use, regulate flexibly the machining accuracy height.
Description of drawings
Fig. 1 is the structural representation of part to be processed;
Fig. 2 is a structural representation of the present utility model.
The specific embodiment
Below further specify the utility model by specific embodiment.
A kind of anchor clamps of clamping deformation when being used to eliminate hole processing, comprise location-plate 1, left feet 21 and right feet 22, technology piece, unsteady back-up block 41 and spring 42, as shown in Figure 2, concrete structure is: left feet 21 and right feet 22 are separately fixed at the left and right sides of location-plate 1 below, the quantity of technology piece is 4, be respectively technology piece 1, technology piece 2 32, technology piece 3 33 and technology piece 4 34, the technology piece all is vertically fixed on the top of location-plate 1 by bolted mode, the back-up block 41 that floats is fixed on the top of technology piece 3 33 by spring.
When present embodiment uses, part to be processed is leaned on last location-plate 1, technology piece and unsteady back-up block 41, and clamped, because the effect of unsteady back-up block is arranged, when chucking power is excessive when making that part to be processed might deformation take place, by the adjusting of spring 42, can the release portion chucking power, thereby avoid the deformation of part to be processed, guaranteed machining accuracy.
