Abstract
Provided is a pressure plate for clamping. A pressure plate body is a rectangular plate structure. The pressure plate for clamping is characterized in that the front end of the pressure plate body is a step-shaped pressure plate head; a groove-shaped step holes are disposed in the pressure plate along the length direction. The pressure plate for clamping is advantageous in that the step-shaped pressure plate head can effectively reduce the height of a clamped part; fixing bolts can be embedded in the pressure plate body through the groove-shaped step holes, preventing the influence of the fixing bolts on a cutter.
Description
Technical field
The present invention relates to the anchor clamps field that the digital control processing clamping is used, particularly a kind of clamping to the digital control processing part is used pressure plate structure.
Background technology
In the digital control processing process, pressing plate is that a kind of clamping workpiece commonly used is used instrument, and it and screw rod, nut, jack etc. are combined to form the clamping to workpiece.Traditional pressure plate structure is simple; It is the elongated plates structure of a band center slotted eye; When using the pressing plate clamping; One endlap of pressing plate is added on the workpiece, and the other end of pressing plate is used the cushion block support with height such as workpiece grade, pressing plate is fixed on the clamping positioning action that realizes on the anchor clamps part with screw rod, nut through the center slotted eye of pressing plate in addition.But traditional pressing plate can increase the height of clamping structure greatly, like this, produces and interferes in order to guarantee cutter in the digital control processing, handle of a knife discord clamping structure, and the length of cutter must increase greatly.The thickness of general pressing plate is 20～30mm, and the nut height is generally 15～25mm, so the length of cutter generally need increase about 50mm.The increase of tool length can reduce the rigidity of cutter greatly, and working (machining) efficiency and surface quality also decrease.
Though can be through reserving fabrication hole on the part, the mode that adopts SOC.HD. cap screw to compress reduces the height of clamping.But in some cases because woollen size-constrained system (for example forging part) also can only adopt the form of pressing plate to carry out clamping.
Summary of the invention
The application has designed a kind of novel pressing plate of using to the digital control processing clamping; This novel pressing plate is through the particular design to pressure plate structure; The clamping height of digital control processing clamping is reduced greatly; Thereby shorten the length of process tool, increase the security of clamping, improve efficiency of NC machining and surface quality.
A kind of clamping is used pressing plate, and the pressing plate body is a rectangular plate shape structure, and the front end that it is characterized in that body is step-like pressing plate head, and the flute profile stepped hole is arranged on the body along its length.
The advantage of the utility model is the height after step-like pressing plate head can effectively reduce parts fixation, and the flute profile stepped hole on the pressing plate body also can be embedded in set bolt in the body of pressing plate, has avoided its influence to cutter.
Below in conjunction with the embodiment accompanying drawing the application is done and to describe in further detail.

Numbering explanation among the figure: 1 lathe platform, 2 workpiece, 3 pressing plates, 4 pressing plate heads, 5 steps, 6 flute profile stepped holes, 7 circular quick-release holes, 8 jack, 9 SOC.HD. cap screws
The specific embodiment
Referring to accompanying drawing, accompanying drawing provides the application's the concrete application of novel pressing plate when the digital control processing clamping.The body of pressing plate 3 is rectangular plate shape bodies, and pressing plate head 4 is slightly narrow, is positioned at the front end of pressing plate, and there is step 5 below of pressing plate head, and the thickness at step place is 5～10mm, and the width at step place is 5～10mm, and concrete size is by being confirmed by the clamping workpiece size; The middle part of pressing plate 3 bodies has flute profile stepped hole 6 along its length, and the width in hole is greater than the diameter of SOC.HD. cap screw 9 heads that cooperate with it, and the step degree of depth in hole is slightly larger than the height of the SOC.HD. cap screw head that cooperates with it; The surface that assurance SOC.HD. cap screw head does not exceed pressing plate gets final product, and the front end of grooved stepped hole 6 is communicated with the circular quick-release hole 7 of a diameter greater than grooved stepped hole width, is used for fast pressing plate being separated with fixture.The more common pressing plate of the thickness of this novel pressing plate is big, thereby increases the integral rigidity of pressing plate, improves its bending strength; Pressing plate is long more, and thickness is big more, but thickness mainly is increased to the bottom of pressing plate, the height in the time of therefore can not influencing the pressing plate clamping.
During application, pressing plate head 4 and step 5 are crimped on the workpiece 2; The afterbody of pressing plate supports with jack 8 or other cushion blocks; SOC.HD. cap screw is used at the middle part of pressing plate, sinks in the grooved stepped hole 6 of pressing plate, thereby pressing plate is fixed on fixation workpiece on the lathe platform 1.When needs dismountings pressing plate or when switching pressing plate, as long as suitably unclamp SOC.HD. cap screw, circular quick-release hole through pressing plate 7 is unloaded it and is got final product from SOC.HD. cap screw.
Because SOC.HD. cap screw 9 sinks in the grooved stepped hole of pressing plate; The head of pressing plate adopts the stepped ramp type design simultaneously, and the clamping maximum height is merely and is higher than about workpiece surface 10mm, greatly reduces the height of clamping structure; Thereby shortened the length of process tool, increased the security of clamping.
Claims (2)
1. a clamping is used pressing plate, and the pressing plate body is a rectangular plate shape structure, and the front end that it is characterized in that body is step-like pressing plate head, and the flute profile stepped hole is arranged on the body.
2. clamping as claimed in claim 1 is used pressing plate, it is characterized in that the front end of described flute profile stepped hole is communicated with the circular quick-release hole of a diameter greater than flute profile stepped hole width.
