Alternatively, the number being arranged on the described clamp for machining on described milling machine is 2.
Alternatively, the base of described each clamp for machining integration connection mutually.
Clamp for machining of the present utility model is due to after putting into L shape step at T-shaped block, pressing plate can be used to be clamped in the rear end of pressing plate and L shape step, now can process, complete plane roughing and fine finishining, the roughing of side both sides and fine finishining, upper plane Drilling operation and counterbore on T-shaped block to process, the dimensional accuracy processed all≤0.1mm, so once fixing can meet repeatedly process, but not process as prior art so once fixing once.It meets daily Production requirement, and improves production efficiency.This clamp for machining is easily manufactured, and cost is low, and positioning and clamping is convenient, and working (machining) efficiency is high, can meet daily tire-mold H380 to concentric mechanism T-shaped block processing request.
According to hereafter by reference to the accompanying drawings to the detailed description of the utility model specific embodiment, those skilled in the art will understand above-mentioned and other objects, advantage and feature of the present utility model more.
Accompanying drawing explanation
Hereinafter describe specific embodiments more of the present utility model with reference to the accompanying drawings by way of example, and not by way of limitation in detail.Reference numeral identical in accompanying drawing denotes same or similar parts or part.It should be appreciated by those skilled in the art that these accompanying drawings may not be drawn in proportion.In accompanying drawing:
Fig. 1 is the overall structure schematic diagram of the clamp for machining according to the utility model embodiment.
Detailed description of the invention
Fig. 1 is the overall structure schematic diagram of the clamp for machining according to the utility model embodiment.In the embodiment shown in fig. 1, disclose a kind of for the clamp for machining of tire-mold H380 to the T-shaped block 1 of concentric mechanism, described T-shaped block 1 comprises larger-size upper rectangular block and the less lower rectangular block of size, comprise: base 2, there is L shape step, for holding the lower rectangular block of described T-shaped block 1, the front end (one end near pressing plate 3) of described L shape step is less than the front surface (one side be close to pressing plate 3) of described T-shaped block 1 and the second distance of rear surface (one side reclined with the rear end of L shape step) with the first distance of rear end (with opposite end, front end), the upper end of described L shape step has the left support block and right support block that are oppositely arranged, after described lower rectangular block is placed into described L shape step, the lower surface of described upper rectangular block contacts with the upper surface of described right support block with described left support block (in stop, rectangular block enters L shape step), pressing plate 3, is removably fixed on described base 2, and the lower end of described pressing plate 3 has rectangular cam, and the difference of described second distance and described first distance equals the ultimate range of described rectangular cam to described pressing plate 3.Make when described pressing plate 3 is fixed on described base 2 like this, the vertical portion of pressing plate 3 can be parallel with the front surface of T-shaped block 1, and arrange the length of pressing plate 3, makes in such cases, the upper end of pressing plate 3 contacts with the front surface of described upper rectangular block, can play fixation better.
As seen from Figure 1, base 2 also comprises the first screwed hole, and be positioned at the position lower than the bottom surface of described L shape step on described base 2, described pressing plate 3 also comprises the second screwed hole; Described pressing plate 3 is fixed on described base 2 through described first screwed hole and described second screwed hole by described first set bolt.In addition, base 2 can also be fixed on milling machine (not shown) by the second set bolt (not shown).
In the embodiment shown in fig. 1, the bottom of described L shape step has boss, when described T-shaped block 1 is put into, described upper rectangular block is supported by described left support block and described right support block and the bottom surface of described lower rectangular block contacts with the upper surface of described boss just.Described boss has two counterbores, position and the T-shaped block 1 of described counterbore need the position being drilled with through hole corresponding, namely T-shaped block 1 put into L shape step and lower rectangular block just to boss time, each counterbore be positioned at T-shaped block 1 one of them need to be drilled with immediately below the position of through hole.
Following simple declaration operating process.Processing contacting with pressing plate 3 below T-shaped block 1 can be put on this clamp for machining after two sides dimensioned puts in place: to be placed on platen holder body after centering X-direction and Y-direction, T-shaped block 1 is put on fixture and can completes Set and Positioning with pressing plate 3 clamping is fixing, clamped one time can complete plane roughing and fine finishining, the roughing of side both sides and fine finishining, upper plain through holes on T-shaped block 1 and processes behind location/and counterbore processes and chamfering, the dimensional accuracy processed all≤0.1mm, meet daily Production requirement, and improve production efficiency.It achieves quick-clamping location, and positioning precision≤0.1mm, also achieve once mounting and locate multistep processing.In addition, because this jig Design has two clamping machine tool faces, so vertical knee-type milling machine and horizontal milling machine all can be general.
In another embodiment of the present utility model, the processing furniture in above-described embodiment can also be used for milling machine, and the clamp for machining that milling machine is installed is at least one (Fig. 1 is 2), and the base 2 of described each clamp for machining can connect mutually in integration.
So far, those skilled in the art will recognize that, although multiple exemplary embodiment of the present utility model is illustrate and described herein detailed, but, when not departing from the utility model spirit and scope, still can directly determine or derive other modification many or amendment of meeting the utility model principle according to content disclosed in the utility model.Therefore, scope of the present utility model should be understood and regard as and cover all these other modification or amendments.
