Detailed Description
The invention will be further described with reference to the accompanying drawings.
As shown in fig. 2, the tool clamp for thin-wall workpiece processing comprises a clamp disc 100, a clamp body 200 and a machine tool pull rod 300; the clamp body 200 is arranged on the clamp disc 100, and a clamp cavity and a working cavity corresponding to the clamp disc 100 are arranged in the clamp body; a baffle ring 210 is fixedly arranged in the clamping piece cavity, the baffle ring 210 divides the clamping piece cavity into a clamping piece hole and a sliding block cavity, a sliding block 220 is slidably arranged in the sliding block cavity, the clamping piece hole is conical, an elastic jacket 230 matched with the clamping piece hole is arranged in the clamping piece hole, the elastic jacket 230 is connected with the sliding block 220 through a connecting piece 240 penetrating through the baffle ring 210, and a spring 250 is arranged between the sliding block 220 and the baffle ring 210; one end of the machine tool pull rod 300 penetrates through the clamp disc 100 and extends into the working cavity, and corresponds to the sliding block 220; the machine tool pull rod 300 can drive the sliding block 220 to move towards the side far away from the clamp disc 100 in the sliding block cavity and compress the spring 250, and the spring 250 in the compressed state can drive the sliding block 220 to move towards the side close to the clamp disc 100 in the sliding block cavity when the machine tool pull rod 300 does not drive the sliding block 220; the elastic collet 230 can move along with the sliding block 220 to extend its cuff out of the clip hole and enlarge the inner diameter, or retract its cuff into the clip hole and reduce the inner diameter.
The tool clamp for processing the thin-wall workpiece is generally connected with a main shaft flange disc of a machine tool through a clamp disc 100 and is connected with a telescopic driving part on the machine tool through a machine tool pull rod 300; when the clamping device works, the sliding block 220 is driven to move towards one side far away from the clamp disc 100 by providing thrust to the sliding block 300 through the machine tool pull rod, the sliding block is pressed tightly by overcoming the elasticity of the spring 250, meanwhile, the elastic jacket 230 moves along with the sliding block 220, the sleeve opening of the elastic jacket 230 extends out of the clamp hole and enlarges the inner diameter, and the thin-wall workpiece 500 is convenient to load; and then the machine tool pull rod 300 is retracted, the spring 250 in the compressed state drives the sliding block 220 to move towards one side close to the clamp disc 100 in the sliding block cavity, the elastic jacket 230 moves along with the sliding block 220, and the sleeve opening of the elastic jacket 230 retracts into the clamp hole and reduces the inner diameter, so that the outer wall of the thin-wall workpiece 500 is wrapped and clamped.
The fixture disc 100 is mainly used for being connected with a spindle flange disc of a machine tool; the fixture body 200 is a main component of the tool fixture for processing the thin-wall workpiece and is mainly used for mounting other parts; the machine tool draw bar 300 is mainly used for connecting with a telescopic driving part on a machine tool so as to automatically clamp and control the thin-wall workpiece 500.
The retainer ring 210 is mainly used to separate the clamp cavity and provide support for the spring 250; the retainer ring 210 may be a ring-shaped member that is fixedly mounted in the clamp cavity, preferably a structure that is integral with the clamp body 200. The elastic jacket 230 is a conical cylindrical part made of elastic material, and is generally provided with a plurality of uniformly distributed through holes so as to expand outwards or contract inwards; the elastic collet 230 mainly plays a role of centering and clamping the thin-walled workpiece 500, and clamping is performed by the reset force of the spring 250. The spring 250 is mainly used for providing a retraction force for the elastic collet 230 so that the elastic collet 230 can automatically clamp the thin-wall workpiece 500 under the action of the conical clamp hole; that is, the force for clamping the thin-walled workpiece 500 is generated by the force of the spring 250, and has no relation with the machine tool drawbar 300, and the advantages of this are: the elastic force of the spring 250 can conveniently adjust the force, because the workpiece wall of the thin-wall workpiece 500 is very thin, generally below 3mm, the clamping force is large and easy to deform, and the force for clamping the outer circle of the thin-wall workpiece 500 cannot be too large but cannot be too small to keep the clamping effect to clamp the outer circle if the inner hole of the thin-wall workpiece is processed with roundness; because the driving force of the machine tool oil cylinder is usually larger and cannot be adjusted to a smaller pulling force, the elastic force of the spring 250 is adopted to enable the elastic jacket 230 to clamp the thin-wall workpiece 500, and the machine tool oil cylinder is not adopted to drive the elastic jacket 230; in practical production, the retraction force of the elastic collet 230 can be controlled according to the type and number of the selected springs 250, so as to control the clamping force of the elastic collet 230 on the thin-wall workpiece 500.
Specifically, as shown in fig. 2 again, the sliding block 220 is generally provided with a spring hole corresponding to the retaining ring 210, and the spring 250 is disposed in the spring hole and has one end abutting against the side surface of the retaining ring 210.
To ensure the uniformity of the clamping force, it is preferable that the number of the springs 250 is at least three, and the springs are distributed in an annular array with the axis of the sliding block 220 as the center line of the annular array.
In order to avoid the relative rotation between the machine tool pull rod 300 and the clamp disc 100 during the working process, as shown in fig. 2, an anti-rotation block 310 is arranged on a rod section of the machine tool pull rod 300 corresponding to the clamp disc 100, and an anti-rotation opening 260 through which the anti-rotation block 310 can pass is arranged on the clamp disc 100.
As a preferred embodiment of the present invention, as shown in fig. 1, fig. 2 and fig. 3, the tool clamp for machining a thin-walled workpiece further includes a pressing mechanism, where the pressing mechanism includes a connecting plate 410 and a rotating column 420;
the connecting plate 410 is arranged in the working cavity and connected with the machine tool pull rod 300;
the rotating column 420 is slidably disposed on the clamp body 200, a shifting groove 421 is formed on a side wall of one end of the rotating column and extends into the working cavity, a pressing plate 422 is disposed on the other end of the rotating column, and a pressing portion of the pressing plate 422 is located on one side of the clamp hole away from the clamp plate 100; a spiral groove 423 is formed in the side wall of the rotating column 420, and a guide column embedded in the spiral groove is formed on the clamp body 200;
the edge of the connecting plate 410 is embedded into the shifting groove 421, and the machine tool pull rod 300 can drive the rotary column 420 to move and rotate towards the side far away from the clamp disc 100 through the connecting plate 410, so that the pressing part of the pressing plate 422 is axially far away from the clamp hole and deflects towards the direction far away from the central line of the clamp hole; the machine tool pull rod 300 can drive the rotary column 420 to move and rotate towards one side close to the clamp disc 100 through the connecting plate 410, so that the pressing part of the pressing plate 422 is axially close to the clamp hole and deflects towards the direction close to the central line of the clamp hole.
When the tool clamp for machining the thin-wall workpiece works, the machine tool pull rod 300 advances to drive the rotating column 420 to move towards one side far away from the clamp disc 100 through the connecting plate 410, and the rotating column 420 with the spiral groove 423 rotates under the guiding action of the guide column, so that the pressing part of the pressing plate 422 axially far away from the clamp hole deflects towards the direction far away from the central line of the clamp hole, the position of a workpiece is released, and the thin-wall workpiece 500 is conveniently loaded into the elastic jacket 230; after the elastic jacket 230 is installed, the machine tool pull rod 300 retracts to drive the rotary column 420 to move towards one side close to the clamp disc 100 through the connecting plate 410, and the rotary column 420 with the spiral groove 423 rotates under the guiding action of the guide column, so that the pressing part of the pressing plate 422 is axially close to the clamp hole and deflects towards the direction close to the central line of the clamp hole, and the end face or the flange of the thin-wall workpiece 500 is pressed through the pressing part of the pressing plate 422.
Because the thin-wall workpiece 500 has larger cutting force in the machining process, the thin-wall workpiece is easy to deform due to overlarge clamping force, and the thin-wall workpiece is likely to slip due to undersize clamping force, the pressing mechanism is designed to drive the pressing plate 422 to stretch and rotate through the machine tool pull rod 300 so as to press the end face or the flange of the thin-wall workpiece 500, provide reliable pressing force, ensure that the thin-wall workpiece 500 does not slip in the machining process, and do not influence the roundness of a machined inner hole.
In order to further improve the effect of compressing and fixing, at least two rotating columns 420 are arranged, and are distributed in an annular array by taking the axial lead of the fixture body 200 as the central line of the annular array.
Preferably, as further shown in fig. 1, the number of the rotating columns 420 is three.
Generally, a tool clamp for machining a thin-walled workpiece is further provided with an air detection air passage, after clamping and pressing the thin-walled workpiece 500, the machine tool performs air detection on the thin-walled workpiece, and after the detection is passed, the machine tool performs automatic cutting on the thin-walled workpiece 500. Specifically, a detection hole is formed in one side end face of the sliding block 220 close to the clamp disc 100, one end of the machine tool pull rod 300 extends into the detection hole and is in clearance sliding fit with the sliding block 220, a sealing element is arranged between the machine tool pull rod 300 and the sliding block 220, and an air passage communicated with the detection hole is formed in the machine tool pull rod 300. Compressed air is introduced into the detection hole from the air passage of the machine tool pull rod 300 and is guided to the end face positioning and supporting part contacted with the thin-wall workpiece 500, so that whether the thin-wall workpiece 500 is clamped in place or not can be detected.
